1/1496. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis. Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits. ( info) |
2/1496. Injection injury of the radial nerve. Four cases of radial nerve palsy following intra-muscular injections into the arm are reported. Recovery occurred in all 4 cases--1 after neurolysis and 3 spontaneously. The mechanism of nerve damage and its treatment are discussed. ( info) |
3/1496. Combined peripheral facial and abducens nerve palsy caused by caudal tegmental pontine infarction. Isolated peripheral facial and abducens nerve palsy could theoretically be caused by a caudal pontine infarction, but as far as we know, there has been no published case history which has demonstrated this point. We describe the cases of two hypertensive patients who showed combined peripheral facial and abducens nerve palsy without other neurologic symptoms or signs. Other than hypertension, there was no identifiable etiology. magnetic resonance imaging demonstrated compatible isolated ipsilateral ischemic infarction of the caudal tegmental pons. The present cases indicate that a well-placed small pontine infarction can cause isolated peripheral facial and abducens nerve palsy. ( info) |
4/1496. Cinefluorography in the diagnosis of pharyngeal palsies. (1) The aetiology of dysphagia may be difficult to diagnose when it presents without clinical signs or an associated clinical syndrome. (2) Pharyngeal palsies present in acute and chronic forms. (3) Cinefluorographic techniques are helpful in making an objective diagnosis of pharyngeal palsy. (4) Advice may be given to the patient on head and neck positions during swallowing that is based on the findings of the cinefluorographic examination, in order to alleviate symptoms. (5) Good fluoroscopy, preferably with video-tape recording facilities may be perfectly adequate provided that the diagnosis is considered at that time. ( info) |
5/1496. Normokalemic thyrotoxic periodic paralysis: a new therapeutic strategy. An unusual presentation of periodic paralysis in a Mexican man with thyrotoxicosis is presented. The patient suffered paralysis of the lower extremities without apparent precipitating factors such as hypokalemia, exercise, carbohydrate or alcohol ingestion. hyperthyroidism was managed first with a thyroid suppressant (methimazole) and propranolol. prednisone was added after another episode of paralysis. Definitive treatment of hyperthyroidism was achieved with radioactive iodine, which subsequently required substitution therapy with thyroxine. A moderate dose of thyroxine (100 microg) caused muscular weakness. Treatment of thyrotoxicosis and flaccid paralysis as well as the effects of glucocorticoids on thyroid function are discussed.

| A case of combined abdominal wall paresis and incisional hernia after laparoscopic cholecystectomy is reported. The paresis possibly occurred by a lesion of the N. intercostalis when extending the incision for stone extraction. Possibly the paresis was a predisposing factor for the development of an incisional hernia. The causes of abdominal wall paresis are explored with a review of the literature. In spite of minimal trauma to the anterior abdominal wall in laparoscopic procedures, the risk of iatrogenic lesions remains. ( info) |
7/1496. peroneal nerve palsy caused by intraneural ganglion. A case of peroneal nerve palsy caused by an intraneural ganglion is presented. The cystic mass was located posterolateral to the lateral femoral condyle and extended along the common peroneal nerve distal to the origin of the peroneus longus muscle. The nerve was compressed in the narrow fibro-osseous tunnel against the fibula neck and the tight origin of the peroneus longus muscle. The nerve was decompressed by complete tumor excision and transection of the origin of the peroneus longus muscle. Full recovery of nerve function was obtained in 6 months. ( info) |
8/1496. Left leg paralysis in a renal transplant. The postoperative course of renal transplant patients is often complicated by opportunistic infection. Up to 4% of posttransplant infections are caused by nocardia species. We present an unusual case of a nocardial spinal cord abscess that caused left leg paralysis. ( info) |
9/1496. Progressive ponto-bulbar palsy with deafness. A clinico-pathological study. Progressive ponto-bulbar palsy with deafness is a rare disease. It seems to be an abiotrophic process with autosomal recessive inheritance in most instances. Only one autopsy case had been briefly described (Lelong et al., 1941). The clinical features and the pathological findings of a new case are reported. The structures primarily involved are the grey matter of the brain stem and the spinal cord, including to some extent the optic tracts and most of the fiber tracts in the brain stem with exception of the pyramidal tracts.

10/1496. An uncommon mechanism of brachial plexus injury. A case report. PURPOSE: To report a case of brachial plexus injury occurring on the contralateral side in a patient undergoing surgery for acoustic neuroma through translabrynthine approach. CLINICAL FEATURES: A 51-yr-old woman underwent surgery for acoustic neuroma through translabrynthine approach in the left retroauricular area. She had a short neck with a BMI of 32. Under anesthesia, she was placed in supine position with Sugita pins for head fixation. The head was turned 45 degrees to the right side and the neck was slightly flexed for access to the left retroauricular area, with both arms tucked by the side of the body. Postoperatively, she developed weakness in the right upper extremity comparable with palsy of the upper trunk of the brachial plexus. hematoma at the right internal jugular vein cannulation site was ruled out by CAT scan and MRI. The only remarkable finding was considerable swelling of the right sternocleidomastoid and scalene muscle group, with some retropharyngeal edema. An EMG confirmed neuropraxia of the upper trunk of brachial plexus. She made a complete recovery of sensory and motor power in the affected limb over the next three months with conservative treatment and physiotherapy. CONCLUSIONS: brachial plexus injury is still seen during anesthesia despite the awareness about its etiology. Malpositioning of the neck during prolonged surgery could lead to compression of scalene muscles and venous drainage impedance. The resultant swelling in the structures surrounding the brachial plexus may result in a severe compression. ( info) |
