This study presents a quantification of the impersistence in the EMG interference pattern (IP) produced during maximal effort by patients with chronic hemiparesis. Monopolar needles were used to record from the flexor carpi radialis (FCR) and extensor carpi radialis longus (ECR) muscles of both the paretic and non-paretic sides of 19 patients with a history of unilateral CVA and 10 healthy control subjects during maximal voluntary isometric wrist flexion or extension. We found more gaps in the IP and fewer total seconds of EMG activity in paretic than in non-paretic or control forearm muscles. The number of gaps was similar in paretic FCR and ECR, but the reduced active time in paretic ECR indicates proportionally more gaps per second of EMG activity. This method provides quantitative measures of both the lapses (gaps in the IP during maximal effort and the inability to sustain EMG activity (total seconds) during long contractions. The latter measure is sufficiently sensitive to distinguish the greater impairment of a paretic wrist extensor than a paretic wrist flexor muscle, and both may prove to be valuable for future comparisons of the severity of paresis and the progress of recovery. These results represent the first quantitative confirmation of previous qualitative descriptions of impersistent recruitment.

Recently a subset of chronic demyelinating inflammatory polyneuropathies with asymmetrical involvement limited to upper limbs, at least at the onset, resembling a multifocal mononeuropathy has been described. Electrodiagnostic testing disclosed multifocal CB outside the common entrapment sites has been described. We report a 55 years old man with a 4 years history of paresis, numbness, fasciculations, myokymia, cramps and mild amyotrophy. Electrophysiological evaluation showed proximal multifocal conduction block and abundant spontaneous activity as fasciculations, myokymia and scarce denervation activity. The importance of taking into account this entity in the differential diagnosis of patients with suspected mononeuritis multiplex or motoneuron disease is emphasized. The nosologic place of this entity is also discussed.

A 24-year-old female was admitted to our hospital on Aug. 20 in 1986 because of blurred vision and right pupillary dilatation. She had sometimes noticed headache later than 1976, and blurred vision without headache several times a year later than 1983. She had been told her right pupil dilated when she had complained of blurred vision. Neurological examination revealed abnormal findings as follows; diminished sense of smell in the right side, anisocoria (R 8 mm, L 5 mm), bilateral hippus, hypesthesioalgesia in her right face, left trunk and left arm. The pupils were round and contracted promptly to light. Accommodation reflex and ciliospinal reflexes were normal. Neither blepharoptosis nor external ocular muscle paresis were observed. Deep tendon reflexes were normal. Planter responses were flexor. There was no meningeal irritative sign. No abnormal findings were obtained in blood and urine, chest X-p, brain enhanced CT scan, EEG, and cerebral angiography except for slight degree of anemia. Serum TPHA was negative. However, the cell count of cerebrospinal fluid (CSF) was 18/mm3 (Ly 100%) and decreased to 9/mm3 (Ly 100%) in nine days. Protein content and glucose level of CSF were normal. Pupils were not constricted by 0.125% pilocarpine instillation. Loss of smell and sensory disturbance disappeared within three days and her pupils became isocoric by five days after admission. The patients of episodic unilateral mydriasis without apparent cause had relatively same clinical features as "unilateral springing pupil" proposed by Hallett et al. (1970). Except for mydriasis, they had no abnormal findings of neurological and laboratory examinations.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical charts and biopsies of 32 children with thyroid nodules were reviewed at the National Children's Hospital from 1970 to 1988. The classification between benign and malignant types was only possible by surgery and biopsy. Twenty three (72%) were found to be benign forms and nine (28%) were carcinomas (8 papillary and one follicular). Two of the carcinomas had been irradiated previously because of neuroblastoma, as well as one of the benign type who received radiation to the neck and mediastinum because of a Hodgkin's disease. No patients showed alteration in thyroid functional test (T4 and TSH). Twenty two per cent of the carcinomas and 16% of the benign forms presented higher retention in the gammagram test. Seventy eight per cent of the carcinomas and 70% of the benign types showed a normal gammagram test. Surgery in the benign cases included 10 hemithyroidectomy, 7 sub-total thyroidectomy, 3 total thyroidectomy and 3 node resection. Carcinoma cases included 6 patients with total thyroidectomy with ganglionar modified dissection in three patients; 2 hemithyroidectomy and one with sub-total thyroidectomy. Complications included 3 hypoparathyroidisms, one of them permanent, 3 transitory recurrent paresis and only one child died because of pulmonary metastasis. All carcinoma patients were treated with levothyroxine and three of them also received 1131 in order to control ganglionar metastasis. Total survival rate for carcinoma patients was 83% at 90 months. It is concluded that only with surgery it is possible to classify correctly the histological type of children with thyroid nodes. Clinical evaluation and laboratory tests are useless. However, it has not been defined how big the surgery must be.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient with a traumatic right third nerve paresis had a contralateral oculomotor synkinesis develop that involved the left upper eyelid. With infraduction in adduction of the nonparetic left globe, the left upper eyelid was elevated. Elevation of the right upper eyelid was present in adduction of the paretic eye but absent in downgaze. To our knowledge this is the first description of the pseudo-Graefe phenomenon developing contralateral to the regenerating paretic third nerve.

Clinical signs in dogs with pseudorabies (Aujeszky's disease) were tabulated from 25 confirmed cases. The duration of disease was short, ranging from 6 to 96 hours. Eight dogs were euthanatized. Of those not euthanatized, 12 (71%) died within 24 hours of onset, 16 (94%) died within 48 hours, and only 1 (6%) lived longer than 48 hours (96 hours) after the onset of clinical signs. All of the dogs had ptyalism, 84% were restless, 84% were anorectic, 76% were atactic, and 64% wandered aimlessly. Sixty-four percent of the dogs had tachypnea, 60% had dyspnea, 56% vocalized, 52% were pruritic, 48% held their necks rigidly, 36% vomited, 36% had muscle spasms, 36% were aggressive, 28% had trismus, and 24% had dysphagia. Five of 25 dogs (20%) had abnormal pupillary light responses. Two of the 25 dogs circled and 2 walked backwards. Each of the following were detected once: blindness, ptosis, facial paresis, excessive lacrimation, head-tilt, head-pressing, signs of abdominal pain, and photophobia. All dogs had been exposed to swine, although in some instances the farmer was unaware pseudorabies existed in the herd or believed it was not in the herd on the basis of negative results on serologic testing.

A 61-year-old woman with Addison's disease and malignant lymphoma for several years was admitted to hospital with a 2-month history of fatigue and a 7 kg weight loss. The erythrocyte sedimentation rate was 92 mm h-1 and a temporal biopsy was performed as a part of the clinical investigation. She suddenly suffered a paresis of the right arm, sudden blindness and her blood pressure fell to 100/60 mmHg. Hydrocortisone was given intravenously followed by betamethasone, and an Addison crisis as well as a giant cell arteritis (GCA) was suspected. Activity in the malignant lymphoma was also a possibility. The patient did not improve and died 8 d later. The temporal biopsy indicated GCA. The autopsy showed a pronounced intimal inflammatory reaction of the intracerebral arteries and an infarction in the left posterior hemisphere. A possible link between GCA and other autoimmune diseases is discussed.

A surgical method is proposed to treat patients with combined severe blepharoptosis and peripheral facial nerve paresis. The operation involves construction of a sling from the contralateral active frontalis muscle to the affected eyelid tarsal plate. The method has been applied in one patient, with satisfactory results. Re-education of the patient was relatively easy to achieve.

Daily doses of 6-aminonicotinamide (3-5 mg/kg) given by ip injection produced ataxia of the hind limbs progressing to an ascending paresis/paralysis, anorexia, diarrhoea and death in male and female New Zealand White and Dutch Belted rabbits. At autopsy, caecal and gastric distention were seen and the apex of the gall bladder had necrotic foci. Light microscopic lesions included atrophy and necrosis of the white lobe of Harder's gland and atrophy of seminiferous tubules with cellular necrosis, vacuolation and the presence of multinucleated giant cells. Cytoplasmic vacuolation was observed in epithelial cells from many tissues, usually in the basal portion of the cells. Vacuolation of the epithelium of the sacculus rotundus and vermiform appendix was found within the same time frame as histiocytic hyperplasia in these organs. Spongiosis and gliosis were seen in certain parts of the central nervous system. Ultrastructural alterations in the gall bladder epithelium consisted of distention of intercellular space, mild distention of perinuclear space and coalescing, intracytoplasmic, membrane-bound vacuoles, a few of which contained membranous debris. Some alterations of 6-aminonicotinamide toxicosis were prevented by simultaneous administration of nicotinamide with 6-aminonicotinamide.

A case of glioblastoma multiforme of spinal cord followed by intracranial dissemination was reported. A 20-year-old man was admitted on Sep. 22, 1981, with motor disturbance of both legs and loss of urinary control. Neurological examination showed spastic paraplegia with bilateral Babinski signs. Abdominal and cremaster reflexes were absent. There was no abnormalities in cranial nerves and upper limbs. Cerebral CT was normal at that time. Myelography showed complete block at the level of 8th thoracic vertebra. Spinal angiography revealed abnormal vascularity at the level of Th7 fed via anterior spinal artery. Intramedullary tumor was partially removed through 5th-8th thoracic laminectomy. Total 5600 rads of irradiation was administered after the operation. The postoperative course was deteriorating. Two months after the operation paresis of both upper extremities had been developed. State of consciousness had been disturbed due to increased intracranial pressure which was subsided for a time while by ventriculoperitoneal shunt. Repeated CT showed high density spots scattered in basal cisterns spreading to all ventricular systems. He expired Feb. 21, 1982. Autopsy revealed that the whole spinal cord was covered by tumor tissue. Basal cisterns were filled with tumor tissue. The tumor was infiltrated subependymally into ventricular systems with intramedullary invasions in some places. Histological diagnosis was glioblastoma multiforme.
