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)

Complications from regional anaesthesia for carotid endarterectomy. (4/67)

The complications of carotid endarterectomy (CEA) under cervical plexus blockade have yet to be fully evaluated.

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 great auricular nerve is a cutaneous branch of the cervical plexus originating from the C2 and C3 spinal nerves. It innervates the skin over the external ear, the angle of the mandible and the par...
The developing auricle is first noticeable around the sixth week of gestation in the human fetus, developing from the auricular hillocks, which are derived from the first and second pharyngeal arches. These hillocks develop into the folds of the auricle and gradually shift upwards and backwards to their final position on the head. En route accessory auricles (also known as preauricular tags) may be left behind. The first three hillocks are derived from the 1st branchial arch and form the tragus, crus of the helix, and helix, respectively. Cutaneous sensation to these areas is via the trigeminal nerve, the attendant nerve of the 1st branchial arch. The final three hillocks are derived from the second branchial arch and form the antihelix, antitragus, and lobule, respectively. These portions of the ear are supplied by the cervical plexus and a small portion by the facial nerve. This explains why vesicles are classically seen on the auricle in herpes infections of the facial nerve (Ramsay Hunt ...

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 ...
A cone biopsy is usually done as an outpatient procedure. You do not have to spend a night in the hospital.. The hospital or surgery center may send you instructions on how to get ready for your surgery. Or a nurse may call you with instructions before your surgery.. You will need to take off your clothes below the waist and drape a paper or cloth covering around your waist. 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.. Medicine that makes you unconscious (general anesthesia) or that makes the entire genital area numb (regional anesthesia, such as a spinal or epidural) may be used.. A cone biopsy using LEEP may be done in your doctors office with an injected medicine that numbs the cervix (cervical block). If a cervical block is used, an ...

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 ...

A 39-year-old woman presented with neck and shoulder pain for 3 months. The MRI scan revealed a cystic-solid lesion located at C5 (figure 1, A-E). The patient received an operation and a small blood blister-like soft mass was detected. The tumor originated from proximal cervical nerve root and compressed the spinal medulla (figure 2, A-C). Pathologic diagnosis was hemangioblastoma (figure 2D). Postoperative gadolinium-enhanced MRI showed a gross total resection of the tumor (figure 1F). Spinal hemangioblastomas frequently originate from the medulla,1 and nerve root originated hemangioblastoma is scarce. Our case provides a direct-viewing description and pathologic confirmation of a new subset of classification for origin of spinal hemangioblastomas. ...
The LON may be easily vulnerable because of its superficial course.. The LON runs vertically upward along the posterior margin of the SCM as a single trunk after it pierced the deep cervical fascia23). Tahir et al.21) reported the use of a horseshoe-shaped headrest during beach-chair surgery caused a permanent injury to the LON, and Park and Kim18) reported three patients with neuropraxia of LON after shoulder arthroscopy. They believed the etiology of injury to LON was an entrapment effect from the headrest compression and recommended that the auricle be protected with cotton or gauze during surgery in the beach-chair position. Though irrelevant to compression injury in this study, LON exposed superficially may also easily be affected from indirect irritations, such as postoperative scar tissue or suture material. However, on cadaveric study, GON was found to emerge below to average 30 mm from the occipital protuberance17).. Group A has less complications related neuropathy because of its ...
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. Neuropathy and loss of sensation often are contributors as well. Other causes include thyroid dysfunction and gastric restriction in obesity. Some infectious diseases, such as leishmaniasis, a rarely reported neurologic change secondary to a bacteria, also may cause burning feet ...

HOW IS IT DONE?. It is typically done with you lying on your stomach for thoracic or lumbar and on your back for cervical blocks. Your vital signs will be monitored. In addition to your doctor and the x-ray technician, there will be a nurse in the room at all times if you have any questions or discomfort during the procedure. The skin on the back or neck is cleansed with antiseptic solution, and then the procedure is performed.. WHAT SHOULD I EXPECT AFTER THE INJECTION?. Immediately after the injection, you may feel your legs or arms, along that specific nerve root, becoming heavy, numb or weak. You may notice that your pain may be gone or considerably less. This is due to the effect of the local anesthetic. Your pain may return, and you may have some soreness at the injection site for a day or so. It is very important to be careful for several hours afterwards to avoid falling due to weakness if done on the lumbar or thoracic spine or dropping or mishandling things with your hand or arm if done ...
