Abducens Nerve Diseases: Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and ESOTROPIA. Common conditions associated with nerve injury include INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; ISCHEMIA; and INFRATENTORIAL NEOPLASMS.Abducens Nerve: The 6th cranial nerve which originates in the ABDUCENS NUCLEUS of the PONS and sends motor fibers to the lateral rectus muscles of the EYE. Damage to the nerve or its nucleus disrupts horizontal eye movement control.Abducens Nerve Injury: Traumatic injury to the abducens, or sixth, cranial nerve. Injury to this nerve results in lateral rectus muscle weakness or paralysis. The nerve may be damaged by closed or penetrating CRANIOCEREBRAL TRAUMA or by facial trauma involving the orbit.Optic Nerve Diseases: Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.Horner Syndrome: A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)Olfactory Nerve Diseases: Diseases of the first cranial (olfactory) nerve, which usually feature anosmia or other alterations in the sense of smell and taste. Anosmia may be associated with NEOPLASMS; CENTRAL NERVOUS SYSTEM INFECTIONS; CRANIOCEREBRAL TRAUMA; inherited conditions; toxins; METABOLIC DISEASES; tobacco abuse; and other conditions. (Adams et al., Principles of Neurology, 6th ed, pp229-31)Cranial Nerve Diseases: Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.Vagus Nerve Diseases: Diseases of the tenth cranial nerve, including brain stem lesions involving its nuclei (solitary, ambiguus, and dorsal motor), nerve fascicles, and intracranial and extracranial course. Clinical manifestations may include dysphagia, vocal cord weakness, and alterations of parasympathetic tone in the thorax and abdomen.Cavernous Sinus: An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.Diplopia: A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.Petrous Bone: The dense rock-like part of temporal bone that contains the INNER EAR. Petrous bone is located at the base of the skull. Sometimes it is combined with the MASTOID PROCESS and called petromastoid part of temporal bone.Trochlear Nerve: The 4th cranial nerve. The trochlear nerve carries the motor innervation of the superior oblique muscles of the eye.Oculomotor Nerve Diseases: Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)Eye Pain: A dull or sharp painful sensation associated with the outer or inner structures of the eyeball, having different causes.Ophthalmoplegia: Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.Hypoglossal Nerve Diseases: Diseases of the twelfth cranial (hypoglossal) nerve or nuclei. The nuclei and fascicles of the nerve are located in the medulla, and the nerve exits the skull via the hypoglossal foramen and innervates the muscles of the tongue. Lower brain stem diseases, including ischemia and MOTOR NEURON DISEASES may affect the nuclei or nerve fascicles. The nerve may also be injured by diseases of the posterior fossa or skull base. Clinical manifestations include unilateral weakness of tongue musculature and lingual dysarthria, with deviation of the tongue towards the side of weakness upon attempted protrusion.Oculomotor Nerve: The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.Oculomotor Muscles: The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.Vestibulocochlear Nerve Diseases: Pathological processes of the VESTIBULOCOCHLEAR NERVE, including the branches of COCHLEAR NERVE and VESTIBULAR NERVE. Common examples are VESTIBULAR NEURITIS, cochlear neuritis, and ACOUSTIC NEUROMA. Clinical signs are varying degree of HEARING LOSS; VERTIGO; and TINNITUS.Glossopharyngeal Nerve Diseases: Diseases of the ninth cranial (glossopharyngeal) nerve or its nuclei in the medulla. The nerve may be injured by diseases affecting the lower brain stem, floor of the posterior fossa, jugular foramen, or the nerve's extracranial course. Clinical manifestations include loss of sensation from the pharynx, decreased salivation, and syncope. Glossopharyngeal neuralgia refers to a condition that features recurrent unilateral sharp pain in the tongue, angle of the jaw, external auditory meatus and throat that may be associated with SYNCOPE. Episodes may be triggered by cough, sneeze, swallowing, or pressure on the tragus of the ear. (Adams et al., Principles of Neurology, 6th ed, p1390)Cranial Nerve Neoplasms: Benign and malignant neoplasms that arise from one or more of the twelve cranial nerves.Onchocerciasis, Ocular: Filarial infection of the eyes transmitted from person to person by bites of Onchocerca volvulus-infected black flies. The microfilariae of Onchocerca are thus deposited beneath the skin. They migrate through various tissues including the eye. Those persons infected have impaired vision and up to 20% are blind. The incidence of eye lesions has been reported to be as high as 30% in Central America and parts of Africa.Trigeminal Nerve Diseases: Diseases of the trigeminal nerve or its nuclei, which are located in the pons and medulla. The nerve is composed of three divisions: ophthalmic, maxillary, and mandibular, which provide sensory innervation to structures of the face, sinuses, and portions of the cranial vault. The mandibular nerve also innervates muscles of mastication. Clinical features include loss of facial and intra-oral sensation and weakness of jaw closure. Common conditions affecting the nerve include brain stem ischemia, INFRATENTORIAL NEOPLASMS, and TRIGEMINAL NEURALGIA.Accessory Nerve Diseases: Diseases of the eleventh cranial (spinal accessory) nerve. This nerve originates from motor neurons in the lower medulla (accessory portion of nerve) and upper spinal cord (spinal portion of nerve). The two components of the nerve join and exit the skull via the jugular foramen, innervating the sternocleidomastoid and trapezius muscles, which become weak or paralyzed if the nerve is injured. The nerve is commonly involved in MOTOR NEURON DISEASE, and may be injured by trauma to the posterior triangle of the neck.Skull Fracture, Basilar: Fractures which extend through the base of the SKULL, usually involving the PETROUS BONE. Battle's sign (characterized by skin discoloration due to extravasation of blood into the subcutaneous tissue behind the ear and over the mastoid process), CRANIAL NEUROPATHIES, TRAUMATIC; CAROTID-CAVERNOUS SINUS FISTULA; and CEREBROSPINAL FLUID OTORRHEA are relatively frequent sequelae of this condition. (Adams et al., Principles of Neurology, 6th ed, p876)Facial Nerve Diseases: Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.Trigeminal Nerve: The 5th and largest cranial nerve. The trigeminal nerve is a mixed motor and sensory nerve. The larger sensory part forms the ophthalmic, mandibular, and maxillary nerves which carry afferents sensitive to external or internal stimuli from the skin, muscles, and joints of the face and mouth and from the teeth. Most of these fibers originate from cells of the TRIGEMINAL GANGLION and project to the TRIGEMINAL NUCLEUS of the brain stem. The smaller motor part arises from the brain stem trigeminal motor nucleus and innervates the muscles of mastication.Paralysis: A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function. (From Adams et al., Principles of Neurology, 6th ed, p45)Duane Retraction Syndrome: A syndrome characterized by marked limitation of abduction of the eye, variable limitation of adduction and retraction of the globe, and narrowing of the palpebral fissure on attempted adduction. The condition is caused by aberrant innervation of the lateral rectus by fibers of the OCULOMOTOR NERVE.Mucocele: A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)Trochlear Nerve Diseases: Diseases of the fourth cranial (trochlear) nerve or its nucleus in the midbrain. The nerve crosses as it exits the midbrain dorsally and may be injured along its course through the intracranial space, cavernous sinus, superior orbital fissure, or orbit. Clinical manifestations include weakness of the superior oblique muscle which causes vertical DIPLOPIA that is maximal when the affected eye is adducted and directed inferiorly. Head tilt may be seen as a compensatory mechanism for diplopia and rotation of the visual axis. Common etiologies include CRANIOCEREBRAL TRAUMA and INFRATENTORIAL NEOPLASMS.Eye Movements: Voluntary or reflex-controlled movements of the eye.Electronystagmography: Recording of nystagmus based on changes in the electrical field surrounding the eye produced by the difference in potential between the cornea and the retina.Nerve Compression Syndromes: Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.Dura Mater: The outermost of the three MENINGES, a fibrous membrane of connective tissue that covers the brain and the spinal cord.Cranial Fossa, Posterior: The infratentorial compartment that contains the CEREBELLUM and BRAIN STEM. It is formed by the posterior third of the superior surface of the body of the sphenoid (SPHENOID BONE), by the occipital, the petrous, and mastoid portions of the TEMPORAL BONE, and the posterior inferior angle of the PARIETAL BONE.Skull Base: The inferior region of the skull consisting of an internal (cerebral), and an external (basilar) surface.Optic Neuritis: Inflammation of the optic nerve. Commonly associated conditions include autoimmune disorders such as MULTIPLE SCLEROSIS, infections, and granulomatous diseases. Clinical features include retro-orbital pain that is aggravated by eye movement, loss of color vision, and contrast sensitivity that may progress to severe visual loss, an afferent pupillary defect (Marcus-Gunn pupil), and in some instances optic disc hyperemia and swelling. Inflammation may occur in the portion of the nerve within the globe (neuropapillitis or anterior optic neuritis) or the portion behind the globe (retrobulbar neuritis or posterior optic neuritis).TurtlesSciatic Nerve: A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.Neurilemmoma: A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance. (From DeVita Jr et al., Cancer: Principles and Practice of Oncology, 5th ed, pp964-5)Peripheral Nerves: The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.Paresis: A general term referring to a mild to moderate degree of muscular weakness, occasionally used as a synonym for PARALYSIS (severe or complete loss of motor function). In the older literature, paresis often referred specifically to paretic neurosyphilis (see NEUROSYPHILIS). "General paresis" and "general paralysis" may still carry that connotation. Bilateral lower extremity paresis is referred to as PARAPARESIS.Cranial Nerves: Twelve pairs of nerves that carry general afferent, visceral afferent, special afferent, somatic efferent, and autonomic efferent fibers.Brain Stem: The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.Optic Nerve: The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.Meningioma: A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2056-7)Nerve Fibers: Slender processes of NEURONS, including the AXONS and their glial envelopes (MYELIN SHEATH). Nerve fibers conduct nerve impulses to and from the CENTRAL NERVOUS SYSTEM.Neurology: A medical specialty concerned with the study of the structures, functions, and diseases of the nervous system.WashingtonTh2 Cells: Subset of helper-inducer T-lymphocytes which synthesize and secrete the interleukins IL-4, IL-5, IL-6, and IL-10. These cytokines influence B-cell development and antibody production as well as augmenting humoral responses.Th1 Cells: Subset of helper-inducer T-lymphocytes which synthesize and secrete interleukin-2, gamma-interferon, and interleukin-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, Th1 cells are associated with vigorous delayed-type hypersensitivity reactions.Withanolides: Ergostane derivatives of 28 carbons with oxygens at C1, C22, and C26 positions and the side chain cyclized. They are found in WITHANIA plant genus and have cytotoxic and other effects.Hospital Bed Capacity, 100 to 299Hospitals, Federal: Hospitals controlled by agencies and departments of the U.S. federal government.

Gradenigo's syndrome. (1/84)

Gradenigo's syndrome, which is characterised by the triad of suppurative otitis media, pain in the distribution of the trigeminal nerve, and abducens nerve palsy may give rise to potentially fatal complications. Knowledge of the aetiology and appropriate investigations can lead to early diagnosis. A case is reported which illustrates this.  (+info)

Transsphenoidal computer-navigation-assisted deflation of a balloon after endovascular occlusion of a direct carotid cavernous sinus fistula. (2/84)

SUMMARY: A 49-year-old woman with a direct posttraumatic carotid cavernous fistula (CCF) was treated with detachable balloons via a transcarotid route. After the procedure, her intracranial bruit, conjunctival injection, and orbital congestion were cured, but the preexistent sixth nerve palsy deteriorated. CT showed one balloon positioned in the posterior portion of the right cavernous sinus and was regarded to be responsible for nerve compression. After surgical exposure by use of a transnasal-transsphenoidal approach under 3D navigation control, this balloon was deflated by puncture with a 22-gauge needle. The previously described symptoms resolved after balloon deflation. This report presents a rare complication of endovascular treatment of direct CCF and a new microsurgical approach to a balloon in a case of nerve compression.  (+info)

Giant ocular nerve neurofibroma of the cavernous sinus: a series of 5 cases. (3/84)

Five cases of giant cavernous sinus neurofibroma arising from the ocular cranial nerves are reported. These patients collected over a period of 5 years consisted of 3 males and 2 females with an age range of 9 to 40 years and a mean of 20.6 years. Clinically, all patients presented with ocular palsies over a long period (mean 3.4 years). All of them underwent a frontotemporal craniotomy along with an orbito-zygomatic osteotomy and excision of the tumour. In patients with extension of the tumour into the orbit, the superior orbital fissure was drilled, the tenon's capsule was cut and the intraorbital portion was excised. The management of these tumours is discussed and the literature reviewed.  (+info)

Abduction paresis with rostral pontine and/or mesencephalic lesions: Pseudoabducens palsy and its relation to the so-called posterior internuclear ophthalmoplegia of Lutz. (4/84)

BACKGROUND: The existence of a prenuclear abduction paresis is still debated. METHODS: In a retrospective design, we identified 22 patients with isolated unilateral (n = 20) or bilateral (n = 2) abduction paresis and electrophysiologic abnormalities indicating rostral pontine and/or mesencephalic lesions. Another 11 patients had unilateral abduction paresis with additional ocular motor abnormalities indicating midbrain dysfunction. Eight of these 11 patients also had electrophysiological abnormalities supporting this location. Electrophysiological examinations in all patients included masseter and blink reflexes (MassR, BlinkR), brainstem auditory evoked potentials (BAEP), and direct current elctro-oculography (EOG). RESULTS: Unilateral MassR abnormalities in patients with unilateral abduction paresis were seen in 17 patients and were almost always (in 16 of 17 patients) on the side of the abduction paresis. Another 11 patients had bilateral MassR abnormalities. BlinkR was always normal. EOG disclosed slowed abduction saccades in the non-paretic eye in 6 patients and slowed saccades to the side opposite to the abduction paresis in another 5 patients. Re-examinations were done in 27 patients showing normalization or improvement of masseter reflex abnormalities in 18 of 20 patients and in all patients with EOG abnormalities. This was always associated with clinical improvement. CONCLUSIONS: Electrophysiologically documented or clinically evident rostral pontine and/or mesencephalic lesions in our patients exclude an infranuclear intrapontine 6th nerve lesion and indicate the existence of an abduction paresis of prenuclear origin. An increased tone of the antagonistic medial rectus muscle during lateral gaze either by abnormal convergence or impaired medial rectus inhibition seems most likely.  (+info)

Idiopathic giant cell granulomatous hypophysitis with hypopituitarism, right abducens nerve paresis and masked diabetes insipidus. (5/84)

A 38-year-old man presented with headache, fever, and double vision associated with right abducens nerve paresis. He had neither nuchal rigidity nor visual field defect. Laboratory data revealed elevated erythrocyte sedimentation rate (ESR), eosinophilia, and lymphocytic pleocytosis in the cerebrospinal fluid (CSF). Provocation tests of pituitary hormones showed partial hypopituitarism. Magnetic resonance imaging (MRI) revealed swelling of the hypophysis and a mass lesion expanding into the right cavernous sinus. The supplement dose of dexamethasone for hypothalamic hypocortisolism manifested diabetes insipidus. Biopsy, carried out through the transsphenoidal approach, revealed giant cell granuloma. Systemic granulomatous diseases were ruled out, and the lesion was considered to be idiopathic giant cell granulomatous hypophysitis. Right abducens nerve paresis, diabetes insipidus and dysfunction of the anterior lobe were amended by the treatment with prednisolone for 4 months, and findings of the pituitary gland and stalk were normalized. The present case shows that glucocorticoid has an effect on amendment of idiopathic giant cell granulomatous hypophysitis.  (+info)

Primitive trigeminal artery variant aneurysm treated with Guglielmi detachable coils--case report. (6/84)

A 69-year-old woman had suffered from diplopia on right lateral gaze for the last 4 months due to right abducens nerve paresis. Right carotid angiography showed a cavernous internal carotid artery (ICA) aneurysm of 17 x 16 x 14 mm size and a primitive trigeminal artery (PTA) variant supplying the territory of the posterior inferior cerebellar artery. Intraluminal occlusion of the aneurysm was performed with 15 Guglielmi detachable coils. The flow of the PTA variant and the ICA was preserved. Right abducens nerve paresis improved partially. PTA variant is a primitive artery originating from the cavernous ICA supplying the cerebellum without opacification of the basilar artery. Only four of the 67 cases of PTA variant were associated with an aneurysm of the PTA variant. The possibility of this rare association should be considered when treating cavernous portion aneurysm because of the risk of cerebellar ischemia.  (+info)

Isolated abducens nerve paresis associated with incomplete Horner's syndrome caused by petrous apex fracture--case report and anatomical study. (7/84)

A 17-year-old male presented with a wound on the right temporal region, oozing hemorrhagic necrotic brain tissue and cerebrospinal fluid, following a fall. Computed tomography showed temporoparietal and petrous apex fractures on the right. Neurological examination revealed abducens nerve paresis, ptosis, and myosis on the right side. The patient was treated surgically for the removal of the free bony fragments at the fracture site and to close the dural tear. The abducens nerve paresis, ptosis, and myosis persisted at the 3rd monthly postoperative follow-up examination. The anatomy of the abducens nerve at the petroclival region was studied in four cadaveric heads. Two silicone-injected heads were used for microsurgical dissections and two for histological sections. The abducens nerve has three different angulations in the petroclival region, located at the dural entrance porus, the petrous apex, and the lateral wall of the cavernous segment of the internal carotid artery. The abducens nerve had fine anastomoses with the trigeminal nerve and the periarterial sympathetic plexus. There were fibrous connections extending inside the venous space of the petroclival area. The abducens nerve seems to be vulnerable to damage in the petroclival region, either directly by trauma to its dural porus and petrous apex or indirectly by stretching of the nerve through the nervous and/or fibrous connections. Concurrent functional loss of the abducens nerve and the periarterial sympathetic plexus clinically manifested as incomplete Horner's syndrome in our patient.  (+info)

Adaptations and deficits in the vestibulo-ocular reflex after sixth nerve palsy. (8/84)

PURPOSE: The effects of paralytic strabismus on the vestibulo-ocular reflex (VOR) have not been systematically investigated in humans. The purpose of this study was to analyze the VOR in patients with unilateral peripheral sixth nerve palsy. METHODS: Twenty-one patients with unilateral peripheral sixth nerve palsy (6 severe, 7 moderate, 8 mild) and 15 normal subjects were studied. Subjects made sinusoidal +/-10 degrees head-on-body rotations in yaw and pitch at approximately 0.5 and 2 Hz, and in roll at approximately 0.5, 1, and 2 Hz. Eye movement recordings were obtained using magnetic scleral search coils in each eye in darkness and during monocular viewing in light. Static torsional VOR gains, defined as change in torsional eye position divided by change in head position during sustained head roll, were also measured. RESULTS: In all patients, horizontal VOR gains in darkness were decreased in the paretic eye in both abduction and adduction, but remained normal in the nonparetic eye in both directions. In light, horizontal visually enhanced VOR (VVOR) gains were normal in both eyes in moderate and mild palsy. In severe palsy, horizontal VVOR gains remained low in the paretic eye during viewing with either eye, whereas those in the nonparetic eye were higher than normal when the paretic eye viewed. Vertical VOR and VVOR were normal, but dynamic and static torsional VOR and VVOR gains were reduced in both eyes in all patients. CONCLUSIONS: In darkness, horizontal VOR gains were reduced during abduction of the paretic eye in all patients, as anticipated in sixth nerve palsy. Gains were also reduced during adduction of the paretic eye, suggesting that innervation to the medial rectus has changed. After severe palsy, vision did not increase abducting or adducting horizontal VVOR gains to normal in the paretic eye, but caused secondary increase in VVOR gains to values above unity in the nonparetic eye, when the paretic eye fixated. In mild and moderate palsy, vision enhanced the VOR in the paretic eye but caused no change in the nonparetic eye, suggesting a monocular readjustment of innervation selectively to the paretic eye. Vertical VOR and VVOR gains were normal, indicating that the lateral rectus did not have significant vertical actions through the excursions that we tested (+/-10 degrees ). Reduced torsional VOR gains in the paretic eye can be explained by the esotropia in sixth nerve palsy. Torsional VOR gain normally varies with vergence. We attribute the reduced torsional gains in the paretic eye to the mechanism that normally lowers it during convergence. The low torsional gains in the nonparetic eye may be an adaptation to reduce torsional disparity between the two eyes.  (+info)

Definition of abducens nerve diseases in the Definitions.net dictionary. Meaning of abducens nerve diseases. What does abducens nerve diseases mean? Information and translations of abducens nerve diseases in the most comprehensive dictionary definitions resource on the web.
Double vision (2 images seen side by side) is the most common symptom. If one eye is involved, the separation between the 2 images is greatest on gaze in the direction of the affected eye (for example, gaze to the left in a left sixth nerve palsy). There is usually less double vision on near fixation than on distance fixation. Children typically do not experience persistent double vision, but are prone to develop amblyopia depending on the severity and duration of the sixth nerve palsy.. ...
The sixth cranial nerve (CNVI) is also named the abducens nerve. It only controls eye movement from the lateral rectus muscle of the eye. The primary action is to help the eye move outward, towards the ear - this action is called ABDUCTION - hence, ABducens nerve. CNVI is unique in that it has a long path to its origin that takes sharp turns. The long pathway, location, and anatomical structures that this nerve courses over make it uniquely susceptible to damage from elevated intracranial pressure.
Case A 17 year old man presented with acute headache and bilateral abducens nerve palsies. CT scan revealed obstructive hydrocephalus caused by a third ventricular lesion. He was managed with a ventriculoperitoneal shunt and biopsies of the lesion were taken. Histologically, the lesion contained non-caseating epitheliod cell granulomas, suggestive of sarcoidosis. He was treated with high dose prednisolone and remained clinically well but follow up brain MRI revealed a significant increase in volume of the third ventricular lesion. Following unsuccessful investigations to find any evidence of systemic sarcoid, the patient underwent a second brain biopsy which confirmed the diagnosis of germinoma. Both the biopsies were done through a craniotomy and transcallosal dissection in order to have a good view of the abnormalities from within the ventricles and recover decent tissue samples that at least macroscopically were representative and large enough to try to prevent sampling error. The patient was ...

A 16-year-old male patient complained of right-sided tinnitus and mild deafness of one-month history. He also had a family history of neurofibromatosis type 2 and a history of a prior operation for left vestibular schwannoma a year ago. Otoneurologic examination revealed moderate sensorineural hearing loss. Magnetic resonance imaging demonstrated multiple extra-axial enhancing masses in the vicinity of both hypoglossal nerves, the right vestibular nerve, the left vestibular nerve, the right trigeminal, the left occulomotor and the right abducens nerves. These findings were evaluated as multiple cranial nerve schwannomas. The case was considered a rare manifestation of neurofibromatosis type 2 without any concomitant abnormality in the central nervous system. Symptomatic medical treatment was initiated and the patient was referred to the neurosurgery department. ...
Discussion In the present study, a retrospective review of cases with fourth and sixth nerve palsies was performed in a strabismus clinic. Many reports are available in the literature concerning etiology of cranial nerve palsies in different types of clinics. We aimed to describe the clinical profile in our clinic. Park et al. [1] analyzed clinical features of acquired third, fourth and sixth nerve palsies in their retrospective study [1]. They stated that sixth nerve was the most commonly affected nerve (52.4%) and vasculopathy was the leading cause (31.1%) [1]. The comparison of these numbers with those of the present study may cause misinterpretation because of the inclusion criteria. Congenital cases were excluded in Park s study [1] however congenital etiology was the most common cause of fourth nerve palsy in the present study. Berlit found the frequency of cranial nerve palsies as follows: 40.1% of sixth nerve palsy and 6.1% of fourth nerve palsy, and the leading cause as vascular causes ...
We opted to perform surgery, and we performed a microsurgical discectomy with minimally invasive left transthoracic access, with a partial posterior corpectomy of T6/7 and placement of an autologous bone graft. During the operation, we had difficulty removing the disc fragment due to its adherence in the posterior portion of the spinal cord and calcification of the local structures (vertebral disc and posterior longitudinal ligament). This caused a dural tear with visible spinal fluid leakage. Primary suturing of the dura mater was not possible; however, the fistula was promptly corrected with a synthetic patch of collagen and fibrinogen (Tachocomb®), without any visible residual fluid leakage during the surgery. A chest tube connected to a waterseal and an external lumbar drain were placed. It is important to emphasize that in cases of CSF leakage, the chest tube should only be placed to waterseal and no suction or negative pressure should be used, as was the case in this report. In the ...

We found the present case when retrospectively reviewing the files of patients with intracranial aneurysm in our institution. It concerns the coexistence of a rare developmental anomaly of the aortic arch vessels and a persistent carotid-vertebrobasilar communication variant. Since no common embryologic basis is known, this association was probably fortuitous. Each of these particular anomalies can pose unique diagnostic and therapeutic difficulties.. ...
The procedure chosen will depend upon the degree to which any function remains in the affected lateral rectus. Where there is complete paralysis, the preferred option is to perform vertical muscle transposition procedures such as Jensens, Hummelheims or whole muscle transposition, with the aim of using the functioning inferior and superior recti to gain some degree of abduction.[10][11][12] An alternative approach is to operate on both the lateral and medial rectii of the affected eye, with the aim of stabilising it at the midline, thus giving single vision straight ahead but potentially diplopia on both far left and right gaze. This procedure is often most appropriate for those with total paralysis who, because of other health problems, are at increased risk of the anterior segment ischaemia associated with complex multi-muscle transposition procedures. Where some function remains in the affected eye, the preferred procedure depends upon the degree of development of muscle sequlae. In a sixth ...
Thyroid eye disease The most common cause of chronic abducens nerve palsy. Graves eye disease, also known as thyroid eye disease, is an autoimmune condition in which immune cells attack the thyroid gland which responds by secreting an excess amount of thyroid hormone. As a result, the thyroid gland enlarges and excess hormones increase metabolism. The hypermetabolic state is characterized by fast pulse/heartbeat, palpitations, profuse sweating, high blood pressure, irritability, fatigue, weig…
Horner syndrome is a combination of signs and symptoms caused by the disruption of a nerve pathway from the brain to the face and eye on one side of the body.. Typically, Horner syndrome results in a decreased pupil size, a drooping eyelid and decreased sweating on the affected side of your face.. Horner syndrome is the result of another medical problem, such as a stroke, tumor or spinal cord injury. In some cases, no underlying cause can be found. Theres no specific treatment for Horner syndrome, but treatment for the underlying cause may restore normal nerve function.. Horner syndrome is also known as Horner-Bernard syndrome or oculosympathetic palsy.. Horner syndrome usually affects only one side of the face. Common signs and symptoms include:. ...
A 59-year-old man with a 1-month history of headache underwent consultation in an otolaryngological clinic of a general hospital. He was diagnosed with nasal septal abscess and was treated with incisional drainage and 1 month of an antibiotic drip; however, his symptoms persisted. The patient later complained of diplopia due to bilateral abducens nerve palsy, and was then referred to the department of Otolaryngology - Head and Neck Surgery, Kobe City Medical Center General Hospital. The septal lesion was biopsied under general anesthesia, and S. apiospermum was detected using polymerase chain reaction. The patient was treated with an antifungal drug and surgical resection of the lesion was performed. Although the patient survived, he lost his eyesight.. CONCLUSIONS ...

BACKGROUND: Transposition techniques alter the muscle paths thereby creating new directions of muscle force. Extraocular muscle transposition procedures have been used to treat abducens palsy, Duanes retraction syndrome, double-elevator palsy and other complex ocular motility abnormalities. The purpose of this study was to evaluate the surgical and functional results of rectus muscle transposition in patients with different aetiologies of severe ocular motility deficits. PATIENTS AND METHODS: Between 1992 and 2008 rectus muscle transposition surgery has been performed on 31 patients. In this retrospective case series one patient with an abducens nerve palsy is presented as an example. In addition, six patients with motility disorders of different aetiologies who had transposition manoeuvers were evaluated. Preoperative, surgical and postoperative data are reported. RESULTS: Rectus muscle transposition has been performed because of severe functional loss of the lateral rectus muscle, the ...

Central nervous system involvement is a rare but serious manifestation of brucellosis. We present an unusual case of neurobrucellosis with transient ischemic attack, intracerebral vasculopathy granulomas, seizures, and paralysis of sixth and seventh cranial nerves. A 17-year-old Caucasian man presented with nausea and vomiting, headache, double vision and he gave a history of weakness in the left arm, speech disturbance and imbalance. Physical examination revealed fever, doubtful neck stiffness and left abducens nerve paralysis. An analysis of his cerebrospinal fluid showed a pleocytosis (lymphocytes, 90%), high protein and low glucose levels. He developed generalized tonic-clonic seizures, facial paralysis and left hemiparesis. Cranial magnetic resonance imaging demonstrated intracerebral vasculitis, basal ganglia infarction and granulomas, mimicking the central nervous system involvement of tuberculosis. On the 31st day of his admission, neurobrucellosis was diagnosed with immunoglobulin M and
Purpose: Vergence movements are slow disconjugate eye movements which may be triggered by image disparity or accommodation. There exist numerous clinical contexts where image disparity may vary with the direction of gaze. A common example is a sixth cranial nerve palsy with increasing image disparity in gaze toward the affected muscle. Adaptive changes to such incomitant image disparity have been poorly investigated and are the scope of this study.. Methods: Vergence stimuli of gaze dependent magnitude were used to mimic the image disparity of an incomitant strabismus. In a first experiment prisms were placed such that stimuli were viewed through the prisms in one gaze direction but not in the other gaze directions. In a second experiment we used a haploscope to modify image disparity according to gaze. We measured vergence responses that were made after a saccade shifting gaze from left to right, with increased image disparity in right gaze. We analysed changes of rise time or slope, latency, ...

For the majority of patients, Duane syndrome does not require surgical treatment. Surgery for Duane syndrome is indicated for one of four reasons:. 1) To reduce a significant deviation in normal straight-ahead position. 2) To eliminate a significant abnormal head position. 3) To eliminate a significant upshoot or downshoot.. 4) To eliminate disfiguring abnormal eyelid position. The goal of treatment is to restore satisfactory eye alignment in the straight-ahead position, eliminate an abnormal head posture and to prevent amblyopia. Eye muscle surgery is not always required. Because the function of the affected nerve and muscle cannot be restored, the other eye muscles are adjusted to compensate and allow for better eye alignment.. ...
Direct CCFs are included among type A fistulas according to Barrows classification. Etiologically, most dissecting CCFs are traumatic, but less commonly they may be spontaneous. Spontaneous direct CCFs are usually caused by rupture of an intracavernous carotid aneurysm, and aneurysmal CCFs account for about 20% of direct CCFs (8).. Spontaneous or traumatic CCF from the persistent trigeminal artery to the cavernous sinus and its endovascular treatment has rarely been reported (2-7). To the best of our knowledge, however, CCF caused by a ruptured aneurysm of the anomalous cerebellar artery has not been reported.. The cerebellar artery originating from the internal carotid artery was first reported by Teal et al (9). The level of the internal carotid artery from which these vessels took origin led to the conclusion that they were persistent trigeminal artery variants (1, 11). Unlike the usual persistent trigeminal artery that has a direct communication with the basilar artery, the persistent ...

OKT3 is implicated as a cause of anterior uveitis in our patient because of onset of inflammation soon after initiating OKT3 therapy, accelerated resolution of inflammation following discontinuation of OKT3, and lack of identifiable infectious aetiologies. We did not further pursue a cause and effect relation through OKT3 rechallenge because renal status had improved. It is unclear whether OKT3 acted alone or in combination to induce uveitis. This type of synergistic drug interaction is reported for rifabutin induced uveitis, which may be potentiated by concurrent administration of fluconazole.3. Ocular side effects of OKT3 include optic neuritis, abducens nerve palsies, conjunctivitis, scleritis, and blindness presumed due to photoreceptor toxicity.4-6 Non-infectious uveitis in patients taking OKT3 is not reported or known to the manufacturer.. While efficacy of OKT3 against allograft rejection is based on suppression of CD3 T lymphocytes, OKT3 side effects may result from stimulation of ...

Error in grep([^[:blank][:cntrl]], \\n, perl = TRUE) : negative length vectors are not allowed As described above, this error occurs on ubuntu 10.04 when R is compiled without optimizations ( I typically use CFLAGS=-ggdb CXXFLAGS=-ggdb FFLAGS=-ggdb ./configure --enable-R-shlib), and the pcre_exec call executed from do_get overwrites the integer nmatches and sets it to -1. This has the effect of making do_grep try and allocate a results vector of length -1, which of course causes the error message above. Id be interested to know if this bug happens on other platforms.

There are several medical and therapeutic interventions for Horner syndrome. Initially, pharmacologic testing is used to determine the presence of Horner syndrome as well as the possible location of the lesion. The use of 4-10% cocaine eye drops versus 1% Hydroxyamphetamine can help to distinguish between second and third order Horner syndrome. In general, a sympathetically denervated pupil will not dilate to cocaine, regardless of the level of the sympathetic interruption because there is a decreased amount of norepinepherine. Hydroxyamphetamine stimulates the norepinepherine release, so an eye with Horner syndrome with damaged postganglionic fibers (third-order neuron lesions) does not dilate as well as the normal pupil after hydroxyamphetamine drops (Bardorf, Van Stavern, & Garcia-Valenzuela, 2001). Because of the sensitivity of using cocaine in a pediatric population, some authors have advanced the use of 1% apraclonidine for pharmacologic testing, but this does not distinguish pre- or post- ...
BACKGROUND AND PURPOSE: Isolated Horner syndrome without associated cranial nerve palsies or ischemic symptoms is an important presentation of spontaneous internal carotid artery dissection (sICAD). Ultrasound is often used as a screening method in these patients because cervical MRI is not always available on an emergency basis. Current knowledge on ultrasound findings in patients with sICAD presenting with isolated Horner syndrome is limited. METHODS: Patients were recruited from prospective cervical artery dissection databases of 3 tertiary care centers. Diagnosis of sICAD was confirmed by cervical MRI and MR angiography or digital subtraction angiography in all patients. Data on Doppler sonography and color duplex sonography examinations performed within 30 days of symptom onset were analyzed. RESULTS: We identified 88 patients with Horner syndrome as the only sign of sICAD. Initial ultrasound examination was performed in 72 patients after a mean time interval from symptom onset to ...
Both neuropathologic, neuroradiologic, and neurophysiologic studies support the hypothesis that Duane syndrome results from an absence of cranial nerve VI (abducens nerve). Neuropathologic evidence comes from postmortem examinations of individuals who had DS14,15. These studies have shown an absence of cranial nerve VI and its correponding alpha motor neurons in the pons, and aberrant innervation of the lateral rectus muscle (the muscle that moves the eye outward towards the ear) by a branch of cranial nerve III. Magnetic resonance imaging (MRI) studies of an individual with DS also revealed the absence of the abducens nerve (cranial nerve VI)16. Neurophysiological evidence for neuronal involvement in DS comes from electromyographic (EMG) studies which show that the medial and lateral recti muscles are electrically active in individuals with DS. When individuals with DS attempt to move their eyes inward (adduct), however, both of these muscles contract at the same time, resulting in the eyeball ...

Duane syndrome type 1 is the most common type of Duane syndrome, an eye movement disorder that is present at birth. People with Duane syndrome have restricted ability to move the affected eye(s) outward toward the ear (abduction) and/or inward toward the nose (adduction). The different types are distinguished by the eye movements that are most restricted. Duane syndrome type 1 is characterized by absent to very restricted abduction and normal to mildly restricted adduction. The eye opening (palpebral fissure) narrows and the eyeball retracts into the orbit with adduction. With abduction, the reverse occurs. One or both eyes may be affected. The majority of cases are sporadic (not inherited), while about 10% are familial. 70% of affected people do not have any other abnormalities at birth (isolated Duane syndrome ...

The Dirk Diggler Story is a 1988 mockumentary short film written and directed by Paul Thomas Anderson. It follows the rise and fall of Dirk Diggler, a well-endowed male porn star. The character was modeled on American porn actor John Holmes. The film was later expanded into Andersons successful 1997 breakout film Boogie Nights. Dirk Diggler (Michael Stein) was born as Steven Samuel Adams on April 15, 1961 outside of Saint Paul, Minnesota. His parents are a construction worker and a boutique shop owner who attend church every Sunday and believe in God. Looking for a career as a male model, Diggler drops out of school at age 16 and leaves home. Jack Horner (Robert Ridgely) discovers Diggler at a falafel stand. Diggler meets his friend, Reed Rothchild (Eddie Delcore), through Horner in 1979, while working on a film. Horner slowly introduces Diggler to the business until Diggler becomes noticeable within the industry. Diggler becomes a prominent model and begins appearing in pornographic films. ...

The reason this hit me like a ton of bricks? Duane Syndrome is caused when a specific cranial nerve does not develop. If this nerve didnt develop, what else didnt develop? What else is lurking behind the scenes? What else do we not know? This news truly was an equilibrium shift for me. I am more wary and concerned. Things I might otherwise write off (like, lack of consonant sounds, I wrote off as being due to the two older kids talking non-stop), I will not write off, I will worry about and focus on trying to identify if there is a bigger issue. Is that better? Maybe. Maybe getting speech therapy at a year is better than getting it at two years, when the problem is more obvious. Maybe not. Maybe being worried that every appointment is going to bring more shocking news is not good for our mental state. But, it is what it is. We dont know what we dont know. And eventually I will slip back into calmness (I hope). For now, I will continue to be wary and hope for the best ...
The trip out involved some peoples flying, some peoples driving, and on the way back it was mostly the reverse, so that every kid got a plane ride. Also, Jeff and I, who drove both ways, could have a rotating group of whiny kids in the not very big cab of the truck that Jeffs dad let us drive but that he thought maybe should be looked at before we go because there could be some sort of grumble, grumble, issue with it, grumble. But off we went (without having the truck looked at, which wasnt MY plan) pulling a Uhaul trailer full of my booth, and our big boys, 12 and just about to turn 11, nestled into the not very big cab of the truck. (I should interject the word cozy here because it should be included but I havent found a factual way to use it in the description of the trip or the truck yet, but doing such, albeit synthetically, might help my mental state, and eventually my market memories. Where was I?) I would say the trip was pretty smooth and uneventful the first evening of driving from ...

purpose. The genetic bases of Duanes retraction syndrome (DRS) were investigated to determine its molecular etiologies. In prior studies, the transcription factors SALL4 and HOXA1 were identified as the genes mutated in DRS with radial anomalies, and in DRS with deafness, vascular anomalies, and cognitive deficits, respectively. Less is known, however, about the genetic etiology of DRS when it occurs in isolation, and only one genetic locus for isolated DRS, the DURS2 locus on chromosome 2, has been mapped to date. Toward the goal of identifying the DURS2 gene, two pedigrees have been ascertained that segregate DRS as a dominant trait.. methods. Members of two large dominant DRS pedigrees were enrolled in an ongoing study of the genetic basis of the congenital cranial dysinnervation disorders, and linkage analysis was conducted to determine whether their DRS phenotype maps to the DURS2 locus.. results. By haplotype analysis, the DRS phenotype in each family cosegregates with markers spanning ...
Background: There are many surgical approaches to treat sixth nerve palsy depend on residual lateral rectus function, which the vertical rectus muscle transpositions (VRT) procedure is the surgical of choice in complete sixth palsy. VRT procedures, including full-tendon and partial tendon transpositions, often are combined with medial rectus muscle weakening. Partial tendon VRT procedure aimed to create success rate similar to full-tendon transposition with reduced risk of anterior segment ischemia when combined with simultaneous ipsilateral medial rectus muscle recession. ...

Abducent nerve is the sixth cranial nerve, which emerges from the skull to operate the lateral rectus muscle. This muscle draws the eye toward the side of the head. Paralysis of the abducent nerve causes inward turning of the eye.
Participants should be able to demonstrate familiarity with afferent neuro-ophthalmic disorders in children (including optic neuritis, optic disc edema and vision loss), be knowledgable concerning the common efferent neuro-ophthalmic disorders that affect children (including diplopia, third/fourth/sixth nerve palsies, and other eye movement abnormalities), and review the relevant neuro-ophthalmic manifestations of systemic disease in the pediatric population ...
Supratentorial epidermoids were 04 cases and infratemporal epidermoids were 19 cases. Clinical features and surgical strategy varies according to the location and extension of the tumors. Age range was 19-71 years (37.46 years). Common clinical features were headache, cerebellar features, seizure, vertigo, hearing impairment and features of raised intracranial pressure (ICP). Investigation was CT scan or/+ MRI of brain in all cases. Pre-operative complete excision was 20 cases, but post-operative images showed complete excision in 17 cases. Content of tumor was pearly white/white material in all cases except one, where content was putty material. Re-operation for residual/recurrent tumor was nil. Complications included pre-operative mortality one case, persisted sixth nerve palsy in one case, transient memory disturbance one case, and extra dural hematoma one case. One senior patient expired three months after the operation from spontaneous intracerebral hemorrhage. Rest of the patients were ...

N2 - We report the association of ipsilateral trigemino-autonomic headache to a case of right-sided nuclear facial and abducens palsy (Gasperini syndrome), ipsilateral hypacusis and right hemiataxia, caused by the occlusion of the right anterior inferior cerebellar artery. Short-lasting attacks of mild to moderate ipsilateral fronto-periorbital head pain, accompanied by lacrimation and mild conjunctival injection during more severe attacks, were present from the onset of symptoms, with a gradual worsening over the next few months and remitting during naproxen therapy. Magnetic resonance imaging showed an infarct in the right cerebellar peduncle, extending toward the pontine tegmentum, also involving the ipsilateral spinal trigeminal ...
Guillain-Barre syndrome (GBS) is an autoimmune disease of the nervous system and is the most common acute polyneuropathy. Both cellular and humoral immunity are believed to be involved in the pathogenesis of GBS, and various types of activated CD4+ T cells are thought to orchestrate the onset and progression of GBS. Lymphoplasma exchange (LPE) filtering out activated lymphocytes while exchanging plasma has been used for GBS treatment for years. However the treatment is still not yet optimal. In order to assess the efficacy of this treatment, we evaluate the effect of LPE and determine the appropriate frequency of LPE treatments for GBS patients through comparing the neurological deficit scores and the changes in related immunology indicators of GBS patients before and after LPE treatment ...

By Megan Bungeroth and Alissa Fleck Last week, State Sen. Tom Duane surprised both the political world and his constituents by announcing his intention to retire at the end of his current Senate term. The seven-term Democratic legislator, who represents parts of the Upper West Side as well as Clinton, Hells Kitchen, Chelsea, the West Village, NoHo and Peter Cooper Village and Stuyvesant Town, has been an accomplished advocate for gay rights as well as health care, and plans to focus on continuing his advocacy outside of Albany. "I wanted to do something else and realized its time to start the next chapter," Duane said in a recent interview. "I would say retire is not a completely accurate term; Im just not ready for re-election. I plan to continue working in my own small way to make the world a better place." Duane, who was elected in 1998 and was New Yorks first openly gay senator, was the first senator to introduce the Marriage Equality Act in 2001 and continued to push for its support ...
The top picture on the left shows a bipinnaria larva of the starfish Pisaster ochraceus. One interesting characteristic of this organism, and the starfish in general, is its ability to regenerate missing body parts both as a larva and as an adult. I read that bisected starfish larvae have been observed to regenerate to form complete larvae within 12-14 days (Vickery and McClintock, 1998). I wanted to see it myself, so on April 13, 2011 I surgically bisected several bipinnarias across the middle, separating the anterior from the posterior portion. The two bottom pictures show the divorced anterior and posterior portions of the bisected larva. I took these pictures within 5 minutes of the surgery. If you look closely you can already see that each fragment is closing the wound! Amazing ...
The 44-year-old songstress layered up in a thick winter coat and chunky scarf as she headed to her dental practice in Highgate in the pouring rain - with a huge umbrella in hand.
This past June just she and I went to Brooklyn to get a feel for it, and just enjoy some time together for four days. Really, the trip of a lifetime. We did nothing special, we didnt have to. On the last night, we took in a French film in a small theater in Soho. Leaving Manhattan into the wee hours of the morning, those cabbies fly. It is funny, how fast, and like a roller coaster. As we approached the Brooklyn Bridge, I thought, there it is: the bridge between where she is now and where she will be at the end of the summer. The summer: the bridge that will give us our last childhood days with her. We were so tired, barely spoke, but both obviously enjoyed the coolness that had cloaked the city after a hot day, windows down, our hair whipping everywhere. Then as we encountered the stretch across the water, I was flooded with memories of her as a baby, a toddler, her bubbly face, her beginnings, the she that almost wasnt mine, and I fought back tears. I couldnt believe we were about to reach ...
