Cervical Plexus: A network of nerve fibers originating in the upper four CERVICAL SPINAL CORD segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head. It also distributes motor fibers to muscles of the cervical SPINAL COLUMN, infrahyoid muscles, and the DIAPHRAGM.Nerve Block: Interruption of NEURAL CONDUCTION in peripheral nerves or nerve trunks by the injection of a local anesthetic agent (e.g., LIDOCAINE; PHENOL; BOTULINUM TOXINS) to manage or treat pain.Submandibular Gland DiseasesAnatomic Landmarks: Reference points located by visual inspection, palpation, or computer assistance, that are useful in localizing structures on or within the human body.Fascia: Layers of connective tissue of variable thickness. The superficial fascia is found immediately below the skin; the deep fascia invests MUSCLES, nerves, and other organs.Anesthetics, Local: Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.Choroid Plexus: A villous structure of tangled masses of BLOOD VESSELS contained within the third, lateral, and fourth ventricles of the BRAIN.

An unusual case of thoracic outlet syndrome associated with long distance running. (1/67)

An amateur marathon runner presented with symptoms of thoracic outlet syndrome after long distance running. He complained of numbness on the C8 and T1 dermatome bilaterally. There were also symptoms of heaviness and discomfort of both upper limbs and shoulder girdles. These symptoms could be relieved temporarily by supporting both upper limbs on a rail or shrugging his shoulders. The symptoms and signs would subside spontaneously on resting. An exercise provocative test and instant relief manoeuvre, which are the main diagnostic tests for this unusual case of "dynamic" thoracic outlet syndrome, were introduced.  (+info)

Ventricular rate control during atrial fibrillation by cardiac parasympathetic nerve stimulation: a transvenous approach. (2/67)

OBJECTIVES: To identify intravascular sites for continuous, stable parasympathetic stimulation (PS) in order to control the ventricular rate during atrial fibrillation (AF). BACKGROUND: Ventricular rate control during AF in patients with congestive heart failure is a significant clinical problem because many drugs that slow the ventricular rate may depress ventricular function and cause hypotension. Parasympathetic stimulation can exert negative dromotropic effects without significantly affecting the ventricles. METHODS: In 22 dogs, PS was performed using rectangular stimuli (0.05 ms duration, 20 Hz) delivered through a catheter with an expandable electrode-basket at its end. The catheter was positioned either in the superior vena cava (SVC, n = 6), coronary sinus (CS, n = 10) or right pulmonary artery (RPA, n = 6). The basket was then expanded to obtain long-term catheter stability. Atrial fibrillation was induced and maintained by rapid atrial pacing. RESULTS: Nonfluoroscopic (SVC) and fluoroscopic (CS/RPA) identification of effective intravascular PS sites was achieved within 3 to 10 min. The ventricular rate slowing effect during AF started and ceased immediately after on-offset of PS, respectively, and could be maintained over 20 h. In the SVC, at least a 50% increase of ventricular rate (R-R) intervals occurred at 22 +/- 11 V (331 +/- 139 ms to 653 +/- 286 ms, p < 0.001), in the CS at 16 +/- 10 V (312 +/- 102 ms vs. 561 +/- 172 ms, p < 0.001) and in the RPA at 18 +/- 7 V (307 +/- 62 ms to 681 +/- 151 ms, p < 0.001). Parasympathetic stimulation did not change ventricular refractory periods. CONCLUSIONS: Intravascular PS results in a significant ventricular rate slowing during AF in dogs. This may be beneficial in patients with AF and rapid ventricular response since many drugs that decrease atrioventricular conduction have negative inotropic effects which could worsen concomitant congestive heart failure.  (+info)

Fast (3 Hz and 10 Hz) and slow (respiratory) rhythms in cervical sympathetic nerve and unit discharges of the cat. (3/67)

1. In seven decerebrate cats, recordings were taken from the preganglionic cervical sympathetic (CSy) nerves and from 74 individual CSy fibres. Correlation and spectral analyses showed that nerve and fibre discharges had several types of rhythm that were coherent (correlated) between population and unit activity: respiratory, '3 Hz' (2-6 Hz, usually cardiac related), and '10 Hz' (7-13 Hz). 2. Almost all units (73/74) had respiratory modulation of their discharge, either phasic (firing during only one phase) or tonic (firing during both the inspiratory (I) and expiratory (E) phases). The most common pattern consisted of tonic I-modulated firing. When the vagi were intact, lung afferent input during I greatly reduced CSy unit and nerve discharge, as evaluated by the no-inflation test. 3. The incidence of unit-nerve coherent fast rhythms (3 Hz or 10 Hz ranges) depended on unit discharge pattern: they were present in an appreciable fraction (30/58 or 52 %) of tonic units, but in only a small fraction (2/15 or 13 %) of phasic units. 4. When baroreceptor innervation (aortic depressor amd carotid sinus nerves) was intact, rhythms correlated to the cardiac cycle frequency were found in 20/34 (59 %) of units. The cardiac origin of these rhythms was confirmed by residual autospectral and partial coherence analysis and by their absence after baroreceptor denervation. 4. The 10 Hz coherent rhythm was found in 7/34 units when baroreceptor innervation was intact, where it co-existed with the cardiac-locked rhythm; after barodenervation it was found in 9/50 neurones. Where both rhythms were present, the 10 Hz component was sometimes synchronized in a 3:1 ratio to the 3 Hz (cardiac-related) frequency component. 5. The tonic and phasic CSy units seem to form distinct populations, as indicated by the differential responses to cardiac-related afferent inputs when baroreceptor innervation is intact. The high incidence of cardiac-related correlation found among tonic units suggests that they are involved in vasomotor regulation. The high incidence of respiratory modulation of discharge suggests that the CSy units may be involved in regulation of the nasal vasculature and consequent ventilation-related control of nasal airway resistance.  (+info)

Cranial and cervical nerve injuries after repeat carotid endarterectomy. (5/67)

BACKGROUND AND PURPOSE: The incidence of cranial and/or cervical nerve injuries after primary carotid endarterectomy (CEA) ranges from 3% to 48%; however, the clinical outcome of these injuries after repeat CEA has not been thoroughly analyzed in the English-language medical literature. This prospective study analyzes the incidence and outcome of cranial nerve injuries after repeat CEA. PATIENTS AND METHODS: This study includes 89 consecutive patients who had repeat CEAs. Preoperative and postoperative cranial nerve evaluations were performed, including clinical examinations (neurologic) and direct laryngoscopy. Patients with vagal or glossopharyngeal nerve injuries also underwent comprehensive speech evaluations, video stroboscopy, fluoroscopy, and methylene blue testing for aspiration. Patients with postoperative cranial nerve injuries were followed up for a long time to assess their recovery. RESULTS: Twenty-five cranial and/or cervical nerve injuries were identified in 19 patients (21%). They included 8 hypoglossal nerves (9%), 11 vagal nerves or branches (12%) (6 recurrent laryngeal nerves [7%], 3 superior laryngeal nerves [3%], and 2 complex vagal nerves [2%]), 3 marginal mandibular nerves (3%), 2 greater auricular nerves (2%), and 1 glossopharyngeal nerve (1%). Twenty-two (88%) of these injuries were transient with a complete healing time ranging from 2 weeks to 28 months (18 of 22 injuries healed within 12 months). The remaining three injuries (12%) were permanent (1 recurrent laryngeal nerve, 1 glossopharyngeal nerve, and 1 complex vagal nerve injury). The recurrent laryngeal nerve injury had a longer healing time than the other cranial nerve injuries. CONCLUSIONS: Repeat CEA is associated with a high incidence of cranial and/or cervical nerve injuries, most of which are transient. However, some of these have a long healing time, and a few can be permanent with significant disability.  (+info)

Evaluation of a cerebral oximeter as a monitor of cerebral ischemia during carotid endarterectomy. (6/67)

BACKGROUND: Stroke is an important contributor to perioperative morbidity and mortality associated with carotid endarterectomy (CEA). This investigation was designed to compare the performance of the INVOS-3100 cerebral oximeter to neurologic function, as a means of detecting cerebral ischemia induced by carotid cross-clamping, in patients undergoing carotid endarterectomy with cervical plexus block. METHODS: Ninety-nine patients undergoing 100 CEAs with regional anesthesia (deep or superficial cervical plexus block) were studied. Bilateral regional cerebrovascular oxygen saturation (rSO2) was monitored using the INVOS-3100 cerebral oximeter. Patients were retrospectively assigned to one of two groups: those in whom a change in mental status or contralateral motor deficit was noted after internal carotid clamping (neurologic symptoms; n = 10) and those who did not show any neurologic change (no neurologic symptoms; n = 90). Data from 94 operations (neurologic symptoms = 10 and no neurologic symptoms = 84) were adequate for statistical analyses for group comparisons. A relative decrease in ipsilateral rSO2 after carotid occlusion (calculated as a percentage of preocclusion value) during all operations (n = 100) was also calculated to determine the critical level of rSO2 decrease associated with a change in neurologic function. RESULTS: The mean (+/- SD) decrease in rSO2 after carotid occlusion in the neurologic symptoms group (from 63.2 +/- 8.4% to 51.0 +/- 11.6%) was significantly greater (P = 0.0002) than in the no neurologic symptoms group (from 65.8 +/- 8.5% to 61.0 +/- 9.3%). Logistic regression analysis used to determine if a change in rSO2, calculated as a percentage of preclamp value, could be used to predict change in neurologic function was highly significant (likelihood ratio chi-square = 13.7; P = 0.0002). A 20% decrease in rSO2 reading from the preclamp baseline, as a predictor of neurologic compromise, resulted in a sensitivity of 80% and specificity of 82.2%. The false-positive rate using this cutoff point was 66.7%, and the false-negative rate was 2.6%, providing a positive predictive value of 33.3% and a negative predictive value of 97.4%. CONCLUSION: Monitoring rSO2 with INVOS-3100 to detect cerebral ischemia during CEA has a high negative predictive value, but the positive predictive value is low.  (+info)

Division of C8 nerve root for treatment of spastic cerebral palsy in the upper limbs: a preliminary report. (7/67)

OBJECTIVE: To investigate the effect of C8 nerve root division on the treatment of spastic cerebral palsy in the upper limbs. METHODS: Two patients were treated with division of the C8 never root. Supraclavicular incision was made to expose the C5-T1 nerve roots. The intraoperative electromyographic recording technique was used to monitor the responses from the flexor digitorum and flexor carpi ulnaris muscle groups simultaneously. The C5-T1 nerve roots were stimulated and the evoked muscle amplitude potentials (EMAP) were recorded from the muscle groups. The EMAP of the muscle groups obtained during electrical stimulation of the C8 nerve root was the largest, which was used as the basis for C8 nerve root division. RESULTS: Division of the C8 nerve root slightly affected the function of the upper limb, and reduced the muscle tone of the flexor wrist and digitorum. CONCLUSION: Division of the C8 nerve root can reduce the muscle tone of the flexor wrist and digitorum in a short time. The long-term effects need to be followed up further.  (+info)

Abnormalities in Schwann cell sheaths in spinal nerve roots of dystrophic mice. (8/67)

Dorsal and ventral spinal roots at cervical, thoracic, lumbar and sacral levels in dystrophic, dy/dy, mice of both 129/ReJ and C57Bl/6J phenotypes showed a complete lack of Schwann cell sheaths of any sort around the majority of their nerve fibres. This condition, termed amyelination, is more extensive (up to 1-5 cm in length) in the longer lumbar and sacral roots than in the shorter roots or in the proximal regions of the sciatic nerve which are also affected to some extent. Amyelination does not appear to be a consequence of myelin or Schwann cell degeneration, as debris is uncommon. Heterozygous carriers are not affected in any obvious way. Myelinated fibres, with Schwann cells of peripheral origin, occur immediately adjacent to the spinal cord in both dorsal and ventral roots, while in dorsal roots unmyelinated fibres also occur, as in normal animals. Amyelinated fibres begin to appear a few internodal lengths away from the cord and are present until near, or within, the dorsal root ganglion, where they become myelinated again. The portion of an axon which has no myelin begins at a normal appearing paranodal region (termed a half node of Ranvier) at the end of a myelin internode. Resumption of myelination likewise begins at a half node. A few myelinated axons may be seen in any given cross section of a root, but as a rule a given myelinated fibre does not remain myelinated throughout the whole length of the root. It is suggested that the nerve lesions develop where the nerves are lengthening rapidly as the animal grows and changes its shape. How these nerve changes release to those in muscle is conjectural.  (+info)

Carotid endarterectomy may be performed by using cervical plexus blockade with local anesthetic supplementation by the surgeon during surgery. Most practitioners use either a superficial cervical plexus block or a combined (superficial and deep) block, but it is unclear which offers the best operative conditions or greatest patient satisfaction. We compared the two techniques in patients undergoing carotid endarterectomy. Forty patients undergoing carotid endarterectomy were randomized to receive either a superficial or a combined cervical plexus block. Bupivacaine 0.375% to a total dose of 1.4 mg/kg was used. The main outcome measure was the amount of supplemental lidocaine 1% used by the surgeon. Subsidiary outcome measures were postoperative pain score, sedative and analgesic requirements before and during surgery, and postoperative analgesic requirements. Median supplemental lidocaine requirements were 100 mg (range 30-180 mg) in the superficial block group and 115 mg (range 30-250 mg) in the
The sternocleidomastoid muscle (SCM) forms a "roof" over the nerves of the superficial cervical plexus (C2-4). The roots combine to form the four terminal branches (lesser occipital, greater auricular, transverse cervical, and supraclavicular nerves) and emerge from behind the posterior border of the SCM (Figure 28-2). The plexus can be visualized as a small collection of hypoechoic nodules (honeycomb appearance or hypo-echoic [dark] oval structures) immediately deep or lateral to the posterior border of the SCM (Figure 28-3), but this is not always apparent. Occasionally, the greater auricular nerve is visualized (Figure 28-4) on the superficial surface of the SCM muscle as a small, round hypoechoic structure. The SCM is separated from the brachial plexus and the scalene muscles by the prevertebral fascia, which can be seen as a hyperechoic linear structure. The superficial cervical plexus lies posterior to the SCM muscle, and immediately underneath the prevertebral fascia overlying the ...

Anastomoses between the transverse cervical cutaneous nerve and the cervical branch of facial nerve are regularly present. The anatomic locations of these anastomoses were poorly documented in the literature. During regular dissection, we came across two of such anastomoses: one of the two anastomoses was identified posterior to submandibular gland, and the other was noted within the parenchyma of the parotid gland. Prior knowledge of anatomic locations of these anastomoses is clinically important as it allows a method for identification and preservation of the cervical branch of the facial nerve as well as a starting point for retrograde facial nerve dissections. In addition, few terminal nerve endings of transverse cervical cutaneous nerve were seen along the retromandibular vein, ducts and some were penetrating the interlobular septa of parotid gland. The functional significance of anatomic variations of its nerve terminal ends deep in the gland is yet to be evaluated.. ...
Carotid Endarterectomy. This site provides a concise visual overview of carotid endarterectomy. Here are the full US 2011 guidelines. The patient may seek advice about carotid stenting, a therapy that, despite initially mixed results avoids the risk of surgery. The CREST study found both to be similar in outcome. This detailed 2011 meta analysis from JAMA Neurology showed surgery to be associated with better results, but not by much.. Carotid endarterectomy may be performed under local or general anaesthesia. Overall perioperative stroke rates average 3% either way. One in three occur in the immediate peri-operative period and the remainder over the next three months. Several multi-centre studies have confirmed that carotid endarterectomy improves outcome for most patients with significant lesions (even if asymptomatic).. Local anaesthesia typically involves appropriate montoring, cervical plexus block, additional infiltration of local by the surgeon and a degree of sedation. The patient should ...
The fascia of the neck comprises the superficial and the deep layers. The deep layer of cervical fascia is further divided into three layers: superficial, middle, and deep. The superficial portion of the deep cervical fascia envelops the sternocleidomastoid and trapezius muscles. It extends superiorly to the hyoid bone where it surrounds the submandibular gland and the mandible. Inferiorly, it attaches to the clavicle and, medially, it forms the floor of the submandibular space as it covers the muscles of the floor of mouth. The middle layer of deep cervical fascia, also known as the visceral or pretracheal fascia, surrounds the infrahyoid strap muscles, the thyroid, the larynx, the trachea, and the esophagus. Below the hyoid, this layer continues inferiorly to fuse with the pericardium. Above the hyoid, this layer continues on the posterior pharyngeal wall as the buccopharyngeal fascia. Between the middle and deep layers of deep cervical fascia is the retropharyngeal space. ...

Objective: We have previously demonstrated a significant incidence of microemboli on diffusion weighted-MRI following CAS. The purpose of this study is to characterize the number, location, and 3-dimensional distribution of infarcts.. Methods: Fifty-three patients underwent CAS and were studied with pre- and post-procedure DW-MRI. Based upon the location and distribution of the ischemic lesions, patients were separated into groups by plotting images on a standard MR brain atlas. Clinical and imaging characteristics were compared between groups to determine associations between type of infarcts and patient demographics, anatomic features, and procedural characteristics.. Results: Twenty-nine patients (55%) were noted on post-procedure DW-MRI to have areas of restricted diffusion consistent with microemboli, although only three (5.7%) had transient neurologic changes resolving by 36 hours, and the 30-day stroke/death rate was 0%. Twelve patients (23%) developed hypotension during the procedure ...

Following a hair transplant surgery, hiccups may develop due to several factors. Some of the main factors to cause this are: the medication that patient takes, possible local irritation of some nerve endings in the donor area (especially in strip technique hair transplant) and lastly, a patients diet.. These three possible causes are each explained in depth below.. Medication: Some medications that are given to the patient after a hair transplant surgery (i.e. - steroids) may increase the chance of developing temporary hiccups.. Diet: In the case that a patient develops hiccups due to his/her eating or drinking habits, his/her diet needs to be controlled. Alcoholic beverages, carbonated beverages or taking in large volumes of food may also increase the chance of developing hiccups.. Local nerve irritation: The local irritation of some nerve endings, such as the posterior auricular nerve or other branches of the cervical plexus may stimulate the phrenic nerve thus also causing hiccups..

This section on the nerves of the neck discusses the anatomy of the cervical plexus and the phrenic nerves.. The cervical plexus is a network of nerves which forms from the anterior rami of C1-C4 within the prevertebral fascia in the posterior triangle of the neck. Its branches can loosely be described as sensory of motor components. Note that the plexus is found bilaterally.. The main sensory branches of the cervical plexus are the greater auricular nerve which innervates the external ear and skin over the parotid gland, the transverse cervical nerve which is responsible for sensation in the anterolateral neck and upper sternum, the lesser occipital nerve which innervates the posterosuperior scalp and the supraclavicular nerves which provide sensation to the skin over the supraclavicular fossa, sternoclavicular joint and part of the upper thorax. These sensory branches enter the skin at the posterior border of sternocleidomastoid (Erbs point).. The numerous motor components of the cervical ...
The phrenic nerve is a nerve that originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. It is important for breathing, as it passes motor information to the diaphragm and receives sensory information from it. There are two phrenic nerves, a left and a right one. The phrenic nerve originates mainly from the 4th cervical nerve, but also receives contributions from the 5th and 3rd cervical nerves (C3-C5) in humans. Thus, the phrenic nerve receives innervation from parts of both the cervical plexus and the brachial plexus of nerves. The phrenic nerves contain motor, sensory, and sympathetic nerve fibers. These nerves provide the only motor supply to the diaphragm as well as sensation to the central tendon. In the thorax, each phrenic nerve supplies the mediastinal pleura and pericardium. The phrenic nerve descends obliquely with the internal jugular vein across the anterior scalene, deep to the prevertebral layer of deep cervical fascia and the transverse ...
The nerve roots are also divided by their anatomic location. These areas are called plexuses and are kind of like bundles of nerves. The main four plexuses in the body are the cervical plexus in the neck area, brachial plexus in the shoulder, the lumbar plexus in the lower back and sacral plexus in the cossyx area. The brachial plexus manages the innervation in the upper extremity. The lumbar plexus deals with the innervation of the hip and knee and also the knee extensor muscles and the sacral plexus manages the rest of the innervation of the lower extremity.. Nerve tissue. Nerves consist mostly from fat. So remember to consume a lot of healthy fats and oils such as olive and coconut oil or avocados for a healthy nervous system. Back to the subject! The anatomical parts of the nerve cell are called the soma, axon and dendrite. The soma is the actual body of the nerve cell. The axon is a long band-like structure that extends from the nerves cell body (soma) to the target joint or muscle. There ...

Definition of ventral ramus of spinal nerve. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
Modern cross sectional imaging has deeply modified the perception of the anatomy of the head and neck because it permits direct identification of the main deep structures. A reappraisal of the anatomy has been proposed by H.R. Harnsberger (1) and has become common ground among head and neck radiologists (although other descriptions exist (2)). The concept of space is superimposed to the traditional presentation of areas (oropharynx, nasopharynx, oral cavity and pharyngo larynx…). French anatomists originally described these spaces in the nineteenth century (3); they are defined by the course of the three layers of the deep cervical fascia (not directly visualized): superficial layer (investing fascia), middle layer (buccopharyngeal fascia), deep layer (prevertebral fascia). The mucosal space is located on the airway side of the pharynx and therefore is not completely fascia-enclosed. The sublingual and submandibular spaces belong to the oral cavity. The advantage of using this terminology is ...
The second stripe has fat attenuation and represents the areolar and adipose connective tissues of the retropharyngeal and retroesophageal spaces.23 The retropharyngeal space is technically considered to extend from the base of the skull to the origin of the esophagus, where it continues inferiorly as the retroesophageal space. These 2 spaces are enclosed by the middle (visceral division) and deep (alar division) layers of the deep cervical fascia and contain a variable amount of lymph nodes superiorly.24 The fat stripe normally lies in close proximity to the anterior surface of the vertebral bodies and displacement can help detect and localize injuries to cervical spine.23 Variation in the thickness and conspicuity of this fat plane can be seen among individuals, but it is always present.25 This could be explained by differences in a patients body habitus, because patient weight has been shown to relate proportionally to the thickness of the PVST on radiographs.26,27 In some patients, this fat ...

Atherosclerosis has been linked directly to smoking and high cholesterol. In addition, diabetes and obesity are also associated with a high risk of developing atherosclerosis.How is it diagnosed?. Carotid stenosis can sometimes be detected by physical exam. When your physician holds the stethoscope against your neck, they may hear a "bruit" or sounds of turbulence in your artery. The diagnosis can be confirmed with an ultrasound of the blood vessels. If the results of the ultrasound are not conclusive a CT scan, MRA (magnetic resonance arteriography) or an arteriogram may be recommended by your physician.. How do I prepare for surgery?. Blood samples will be needed as well, as an EKG and chest X-ray. Depending on your health and medical history, your doctor may recommend a cardiac stress test to determine if your heart can withstand the stress of an operation. If you have lung disease, your doctor may also suggest tests of pulmonary function to help the anesthesiologist manage your lungs while ...

Local tissue damage (either by direct or indirect mechanisms) causes focal neurologic symptoms, which vary due to the location of the brain tumor. Hemiparesis, aphasia, difficulty speaking, ataxia, hemihypoesthesia (numbness and decreased sensation of touch on one side of the body) and localized headache are some of the symptoms occurring due to the local effects of the brain tumor. Increased pressure in the skull or brain edema cause more generalized symptoms like generalized headache, nausea and vomiting, loss of consciousness (stupor or coma) and intellectual decline. Seizures due to the local irritating effect of the brain tumor or metabolic changes caused by the cancer are also frequently observed. Since the development of the skull is incomplete during infancy, infants with brain tumor may have increased head perimeter, bulging fontanelles or separated sutures. Neurologic examination reveals local (specific to the location of the tumor) or generalized neurologic changes. Slowly progressive ...
Burning feet are a common complaint among many groups of people, most commonly those over 50 years of age and in diabetics. There are many causes. Heavy alcohol use may lead to the condition.

The JC virus, or John Cunningham virus, is a member of the polyomavirus family. When youre exposed to it as a kid or young adult, you might not even notice it, or you might notice cold-like symptoms which are self-limiting. Not a huge deal at all. You get infected, you make antibodies, life goes on. As long as youre immunocompetent. But thats not the case in patients with impaired cellular immunity, as in cases of Hodgkins lymphoma (HL).. Although the gold standard for diagnosis is brain biopsy, you dont need tissue to make the diagnosis of PML. In an immunocompromised patient with progressive neurologic changes, youll always need the MRI. This can exclude opportunistic processes like toxoplasmosis, cryptococcal meningitis, or CNS lymphoma, but will also be important to confirm the presence of white matter disease, which may or may not have enhancement 10-20% of the time, and may or may not have mass effect. Our patient had faint enhancement, as you can see from the images on the blog. Once ...
Purpose: Both conjunctivas are regarded as immunologically independent from each other, but there is anecdotal evidence that one ocular surface might condition its fellow. The purpose of this work was to evaluate the effect that a corneal lesion on one eye exerts over the conjunctival immune response of the opposite eye and the potential mechanisms involved.. Methods: An unilateral controlled chemical burn with NaOH was induced in the cornea of 8-week-old female Balb/c mice (day 1, 3 animals/group, n=4), which were then instilled ovalbumin (OVA) daily (days 2-5) either in the same or the fellow eye. Mice were then immunized with OVA in adjuvant (day 8) and their T cell responses were measured by delayed-type hypersensitivity (DTH) assays in the footpads (day 15). Some mice underwent unilateral superior cervical sympathectomy one week before corneal burn. To assess lymphatic drainage pathways, fluorescent OVA was injected in the subconjunctival space of one eye and 2 hours later each cervical ...

The only treatment available for reversing the effects of a stroke is a drug that breaks down blood clots called tPA. This drug can only be given within 4½ hours of the stroke onset, hence it is very important to get to hospital as soon as possible after stroke symptoms begin. Not all patients are suitable for this treatment. It can only be given after the patient has been assessed by an experienced neurologist and after CT scan is done.. Patients with stroke are best cared for in dedicated stroke units in a hospital setting. Supportive care for stroke includes giving antithrombotic medication to reduce the risk of recurrent stroke, treatment for lowering blood pressure and cholesterol, controlling glucose levels, managing complications of stroke, specialised nursing care and rehabilitation of the patients disabilities with physiotherapy, occupational therapy, and speech/ swallowing therapy. Some patients may also benefit from carotid artery surgery or stenting to reduce the risk of future ...

Metachromatic leukodystrophy (MLD) is a lysosomal storage disorder caused by a deficiency of the arylsulfatase A (ARSA) enzyme, which leads to the accumulation of galactosyl sulfatide (cerebroside sulfate) in the white matter of the central nervous system and in the peripheral nervous system. Galactosyl sulfatide and, to a smaller extent, lactosyl sulfatide, also accumulate within the kidney, gallbladder, and other visceral organs and are excreted in excessive amounts in the urine.. The 3 clinical forms of MLD are late-infantile, juvenile, and adult, depending on age of onset. All result in progressive neurologic changes and leukodystrophy demonstrated on magnetic resonance imaging. Late-infantile MLD is the most common (50%-60% of cases) and usually presents between age 1 to 2 years with hypotonia, clumsiness, diminished reflexes, and slurred speech. Progressive neurodegeneration occurs and most patients die within 5 years of the diagnosis. Juvenile MLD (20%-30% of cases) is characterized by ...

Pain began in hospital immediately after awakening from right carotid artery surgery. Nurses said pain was from intubation and would go away in a few days. That was 5 months ago.Dont even have to chew. Just introducing food or drink causes excruciating pain on right cheek, jaw. First two chews painful and then pain goes away until next meal. Dental surgeon said its not my salivary glands or TMJ.Digastric muscle was cut during surgery. Surgeon said he never heard of these symptoms after surgery.A dentist noted that I have 3 teeth in permanent bridges that havent had root canal and said its probably one of those but cannot tell which one. There is no infection.

PurposeTo assess the pelvic circulation during abdominal aortic aneurysm (AAA) repair by measuring the inferior mesenteric artery stump pressure (IMA-SP), penile blood flow, and gluteal blood flow.MethodsTwenty males were selected for this study. An aorto-bi-common iliac arteries (CIA) graft replacement was performed in ten patients (Group Bi-CIA). An aorto-right-CIA/left-external iliac artery (EIA) graft replacement was performed in five (Group Lt-EIA). The other five underwent an aorto-right-EIA/left-CIA anastomosis (Group Rt-EIA). The right graft limb was anastomosed first, followed by the left limb in all of the patients. Pelvic circulation was monitored during aortic reconstruction, including the IMA-SP index (IMA-SPI), penile brachial pressure index (PBI) by pulse-volume plethysmography, and gluteal tissue oxygenation metabolism with near-infrared spectroscopy by monitoring the gluteal tissue oxygenation index (TOI) bilaterally.ResultsThe PBI and bilateral gluteal TOI became depressed in all

You will then lie on your back on an exam table with your feet raised and supported by footrests (stirrups). Your doctor will insert a lubricated tool called a speculum into your vagina. The speculum gently spreads apart the vaginal walls, allowing the inside of the vagina and the cervix to be examined.. The procedure is usually done with a numbing medicine injected into the cervix (cervical block). If a cervical block is used, an oral pain medicine may be used along with the local anesthetic.. ...
The reported signs and symptoms of low pathogenic avian influenza (LPAI) A virus infections in humans range from conjunctivitis to influenza-like illness (e.g., fever, cough, sore throat, muscle aches) to lower respiratory disease (pneumonia) requiring hospitalization.. Highly pathogenic avian influenza (HPAI) A virus infections in people have been associated with a wide range of illness from conjunctivitis only, to influenza-like illness, to severe respiratory illness (e.g. shortness of breath, difficulty breathing, pneumonia, acute respiratory distress, viral pneumonia, respiratory failure) with multi-organ disease, sometimes accompanied by nausea, abdominal pain, diarrhea, vomiting and sometimes neurologic changes (altered mental status, seizures).. ...
Results show that anti-inflammatories may prevent many neuropathologic effects of lyme neuroborreliosis, according to study published in the American Journal of Pathology. Philadelphia, PA, April 16, 2015 - About 15% of patients with Lyme disease develop peripheral and central nervous system involvement, often accompanied by debilitating and painful symptoms. New research indicates that inflammation plays a causal role in the array of neurologic changes associated with Lyme disease, according to a study published in The American Journal of Pathology. The investigators at the Tulane National Primate Research Center and Louisiana State University Health Sciences Center also showed that the anti-inflammatory drug dexamethasone prevents many of these reactions.. "These results suggest that inflammation has a causal role in the pathogenesis of acute Lyme neuroborreliosis," explained Mario T. Philipp, PhD, Professor of Microbiology and Immunology and chair of the Division of Bacteriology and ...
The presentations of MBD are variable. In the acute stage, the patient often has nonspecific neurologic changes, such as confusion, coma, seizure, dysarthria, and hemiparesis.2,3 Classic interhemispheric disconnection syndrome is often obscure in patients with confusional state, and it has often been misdiagnosed as Wernicke encephalopathy, alcohol withdrawal syndrome, or encephalitis. The early diagnosis depends on MR imaging. Conditions with acute onset, impairment of consciousness, widespread lesions, and cortical involvement indicate an unfavorable prognosis.2,3. The characteristic MR imaging findings are symmetric lesions of the corpus callosum. Lesions may be also found in the hemispheric white matter, cortex, middle cerebellar peduncles, and internal capsules.3,4 During the acute phase, the affected areas demonstrate edematous change with or without demyelination, appearing hypointense on T1WI and hyperintense on T2WI. After the acute stage, edematous change may subside and the corpus ...
Neuroblastoma (NB) is a paediatric form of cancer derived from the sympathetic nervous system. Recent genome-wide sequencing data suggest that often NB does not have a clear genetic cause, leading the authors to hypothesize that NB results from aberrations of normal development. To test this hypothesis, Anna Philpotts group used a population of anteroventral noradrenergic (AVNA) cells from Xenopus embryos. These cells share several features with mammalian sympathetic neurons, including the expression of noradrenergic-associated genetic markers such as the achaete-scute complex-like 1 (Ascl1) gene, which encodes a transcriptional driver of neurogenesis. By comparing AVNA and NB cells, the authors found that, whereas Ascl1 is only transiently expressed in AVNA cells, it is aberrantly maintained in NB, where it is phosphorylated on multiple serine-proline sites. The authors then show that differentiation of AVNA cells is enhanced by dephosphorylated Ascl1. Moreover, this process is inhibited by ...

The patient had carbon monoxide poisoning, which caused respiratory insufficiency, neurologic changes (loss of consciousness and visual impairment) and cardiac dysfunction (elevated troponin I, creatine kinase-MB fraction and carboxyhaemoglobin levels, and left ventricular dysfunction). Visual field defect is a significant outcome of occipital lobe infarct,(4) and the diffusion restriction observed in the left occipital lobe of our patient is evidence that the vision loss resulted from an occipital lobe ischaemic infarct.. Carbon monoxide inhibits the mitochondrial electron transport system and activates polymorphonuclear leucocytes that cause brain lipid peroxidation. This process may explain the delayed outcomes of carbon monoxide intoxication such as late encephalopathy.(5) Acute brain injury in patients exposed to carbon monoxide is usually caused by hypoxia. Neurons normally require major amounts of oxygen and glucose, and they are the cells in the central nervous system that are most ...

The principal goal of monitoring during CEA is to identify possible causes of neurological impairment sufficiently early to allow prompt correction of the cause. Mental status evaluation during carotid cross-clamping while the patient is awake remains the gold standard with which other methods of monitoring should be compared. Under general anesthesia, monitoring with EEG remains the gold standard. In our study of 193 patients TCO was evaluated under general anesthesia, for detecting cerebral ischemia during cross-clamping of the carotid artery for CEA. TCO showed a decrease greater than 20% in 24 patients. In all these cases some maneuvers by anesthesiologists were made as hypertension and hypercapnia (40-45 mmHg) induction to restore the TCO normal range . In this case a shunt was never placed and no neurological problems occurred. We believe that under general anesthesia, TCO is a practical and non-invasive monitoring system with high sensitivity. ...
A contrast dye is injected to identify the area to be injected and then with the aid of a fluoroscope (a type of x-ray machine) to guide the needle, the medications are injected into the area around the plexus. Often a preliminary injection of local anesthetic will be used to determine if the patient will benefit from a superior hypogastric plexus block, if it is determined that the procedure will be effective a more permanent analgesic will be injected (such as phenol). After the procedure has been completed the patient will be placed in an observation area to watch for an allergic reaction to the medications. ...

Carotid Artery Surgery, also known as carotid endarterectomy, is a procedure in which blood vessel blockage is surgically removed from the carotid artery in your neck. Surgery is commonly done when there is blockage in the carotid artery, to improve blood flow to your brain and reduce the risk for a stroke.. Continue Reading → ...
EXPERT CONSENSUS for MANAGEMENT: Surgical morbi-mortality is higher than in the normal population and the risk of anesthetic complications is very high: these patients must therefore be managed in facilities where care of those complications can be taken.. It is why : - a full neurological examination is necessary before general or locoregional anesthesia. - imaging (MRI or CTscan) of the full spine is recommended - a flexion/extension MRI of the cervical spine is necessary if there is any concern about its stability. - polysomnography, respiratory functional tests (restrictive or obstructive syndrome) and cardiac evaluation (echocardiography) must be considered before an anesthesia. - morphological and functional anomalies of the upper airway, a decrease in mobility of the cervical spine and bronchial airway anomalies increase the morbidity and mortality of anesthesia. - a sedative premedication can be administered before anesthesia. - for intubation, a videolaryngoscope and a intubating ...
The facet of the tubercle of the rib forms an articulation with the adjacent transverse process of a thoracic vertebra. This is a plane type synovial joint called the costotransverse joint. This articulation is present in all but the eleventh and twelfth ribs. Ribs 1 to 10 have two joints in close proximity posteriorly; the costovertebral joints and the costotranseverse joints. This arrangement restrains the motion of the ribs allowing them to work in a parallel fashion during breathing. If a typical rib had only one joint posteriorly the resultant swivel action would allow a rib to be non-parallel with respect to the neighboring ribs making for a very inefficient respiratory mechanism. The ventral rami innervate the costotransverse joints. Therefore, therapeutic medial branch blocks are ineffectual. ...
Position of Head at Impact. The position of the patients head at the moment of impact was the "third and most relevant factor" in this study. The authors found:. A rotated head position led not only to severe muscular ligamental strain, but also to a greater risk of damage to cervical nerve roots. Suffering a rear-end collision with the head inclined leads to higher acceleration forces and more severe injury to cervical structures. Rotated or inclined head position was the only accident feature related to injury severity according to our grading system, which is based upon presenting symptoms and signs. The physiologically permitted range of extension is much smaller and reduced by 50% when the neck is rotated. Rupture of the anterior longitudinal ligament is more readily produced in experiments done with cadavers when the head is rotated before an extension strain is applied to the neck.. Research into acceleration-deceleration type injuries has helped to generate an understanding of the ...

Article abstract-The postoperative hyperperfusion syndrome describes an abrupt increase in blood flow with loss of autoregulation in surgically reperfused brain. Reports described a spectrum of findings, including severe headache, transient ischemia, seizures, and intracerebral hemorrhage. Hypertension is common after carotid artery surgery and often plays a role in the pathophysiology. We now report five patients with severe white matter edema after carotid surgery, a finding not previously included in the hyperperfusion syndrome. Five to 8 days after carotid surgery and after hospital discharge, each patient developed hypertension, headache, hemiparesis, seizures, and aphasia or neglect due to severe white matter edema ipsilateral to the carotid surgery. One patient had a small hemorrhage within the edematous area. Hypertension was severe in four patients and moderate in one. The carotid artery was patent by ultrasound or angiography in each patient after surgery. Transcranial Doppler showed ...
Objective To investigate the relationship between twirling reinforcement-reduction method and effect of reinforcement-reduction.Method Wistar male rats(n=50) were randomly divided into group A,B,C,D and E(each n=10).Besides group A the model of stress-induced hypertension was established by foot-shock and noise stimulation is other groups.Group A and B were assigned as the control group,group C was treated with acupuncture only,group D with twirling reinforcement method in left Taichong(LR3),and group E with twirling reduction method in left Taichong(LR3).The discharge of cervical sympathetic nerve in different groups was observed at a moment of needling.Result Before acupuncture the discharge frequency histograms and integrals in group B,C,D and E greatly increased compared with those in group A,which indicated that the discharge of cervical sympathetic nerve and blood pressure increased after the model establishment.After acupuncture there was a significant difference between group D and group B or

Each phrenic nerve controls the movement of the hemidiaphragm and provides the sensory innervation to the middle of the diaphragm, some parts of the pleura and pericardium. The phrenic nerve originates mainly from the 4th cervical nerve, but also receives contributions from the 3rd and 5th cervical nerves (C3-C5) in humans. The three nerves join at the upper lateral portion of the anterior scalene, forming the phrenic nerve. The nerve descends obliquely across the anterior scalene, through the gap between sternocleidomastoid and omohyoid muscles, and deep into the thorax. The right phrenic nerve follows the course of the vena cava to provide motor innervation to the right hemidiaphragm. The left phrenic nerve descends to provide motor innervation to the left hemidiaphragm in a course parallel to that of the vagus nerve.. The phrenic nerve is sonographically visualized as a solitary round hypoechoic structure of about 0.76 mm. However, visualization of the phrenic nerve can be considered as ...

to help ease your pain!. Remember if youre concerned about your pain or have experienced your pain for a few consecutive days make sure you consult your Physio or GP!. What is it?. Cervicogenic headache is a syndrome characterised by pain around the head or face that is referred from a source in the neck. Often this pain is referred from the soft tissue or bony structures.. The prevalence of this type of headache in the general population is only around 2-4%. They are most common around the age of 40 and are 4 times more likely in females than males. They can also affect quality of life to the same extent as migraines! The most common factors related to these headaches are mental stress and poor neck position (posture, weak or tight muscles).. The mechanism of this pain is thought to arise from a crossover of information from the nerves supplying the neck and those that supply the head and face. This occurs with a convergence between the sensory fibres from the upper cervical nerve roots and ...
HOW IS SEXUALITY AFFECTED?. A 2006 study by Demirkiran and colleagues showed that more than 80% of patients with MS experienced sexual dysfunction. Foley and colleagues developed a conceptual model of sexual difficulties in people with MS that comprises three levels. In this model, primary sexual dysfunction occurs as a result of neurologic changes directly affecting sexual response or feelings (or both). According to a study by McCabe and colleagues, women most commonly describe altered genital sensations, diminished vaginal lubrication, difficulty achieving orgasm, and a loss of desire. Men experience difficulty achieving and maintaining erections as well as ejaculatory problems (failing or taking too long to ejaculate; the rate of premature ejaculation in the study wasnt statistically different from that in the general population). Secondary sexual dysfunction is caused by MS-related physical changes that dont directly affect sexual functioning through nervous system pathways. Examples of ...
