A case of hypertrophic interstitial neuropathy in a 32 years old man developed in the median nerve is reported. This is a rare disease characterized by thickened peripheral nerves which may be palpable and visible. This case was treated by excision of transverse carpal ligament and external and internal neurolysis.

PURPOSE: Nitric oxide(NO) is a highly reactive messenger molecule that is synthesized by nitric oxide synthase(NOS) in a number of tissues including the brain. Our aim was to examine the possible role of NO on pentylenetetrazole(PTZ)-induced seizure in rats as a proconvulsant or an anticonvulsant. METHODS: Male Sprague-Dawley rats weighing 200-300g were used. PTZ(40mg/kg) was used to induce seizure. In order to examine the role of NO in seizures, the neuronal nitric oxide synthase (nNOS) was blocked by a specific inhibitor, 50mg/kg 7-nitroindazole(7-NI), and a non-specific inhibitor, 50mg/kg L-nitroarginine(L-NA). Both 7-NI and L-NA were administered 30 min before the administration of PTZ. We evaluated the onset time of the first myoclonic jerk and the nature of seizures, such as the types and severity of the seizures in each group. Western blot and RT-PCR were used to examine the expression of nNOS mRNA and proteins in the hippocampus of each group. RESULTS: The onset time of the first rnyoclonic jerk was markedly delayed in the 7-NI and L-NA pretreated groups in comparison to the PTZ group. In addition, 7-NI and L-NA markedly sup- pressed the severity of PTZ-induced seizure. The expression of nNOS mRNA was higher in the PTZ and 7-NI pretreated groups than in the control group. The expression of nNOS protein was more suppressed in the 7-NI and L-NA pretreated groups than in the PTZ group. CONCLUSION: The expression of nNOS protein appears to increase in PTZ-induced seizures. Both specific and non-specific NOS inhibitors produce a reduction in seizure activity and nNOS protein expression. These results suggest that nNOS may be in a close relationship with seizures, and NO may play an important role as a proconvulsant in the PTZ-induced seizure in rats.

Atrial septal defect is one of the most common congenital heart diseases in adult, of which absolute causes is not confirmed, but explained by multifactorial inheritance. In Korea, there has been no case report of atrial septal defect in identical twins in spite of some reports of atrial septal defect in relatives and twins in other countries. We present a first case of atrial septal defect in identical twins whose mother had no infection or medication history during pregnancy.

A clinical trial was done to evaluate the antihypertensive efficacy and side effects of manidipine, a new calcium antagonist, in 30 patients with mild to moderate essential hypertension. 1) The study patients consisted of 19 men and 11 women, and the mean age was 51.8 years. 2) Blood pressure dropped significantly in 2 weeks and in 4 weeks, and well maintained throughout the study period. The mean-pressure drop was 26.2/14.9mmHg after 10 weeks. 3) Heart rate did not change significantly with manidipine therpy. 4) Optimal dose for effective pressure-drop was between 10 and 20 mg in 86% of patients. Overall good antihypertensive effect was achieved in 83% of patients. 5) All of the laboratory parameters including blood chemistry, glucose, lipid and electrolytes did not change, but serum calcium increased from 9.2% mg/dl (p=0.001) in 10 weeks. 6) Side effects were mild in nature(palpitation in 3, dry mouth in 1, weakness in 1 and impotence in 1 patient). In conclusion, manidipine monotherapy with 10 to 20 mg once a day regimen is effective and well tolerated in the patients with mild to moderate essential hypertension.

Tension pneumocephalus is rare complication is neurosurgical operation. But it should be treated promptly because of sudden neurological deterioration. Computed tomography permitted rapid diagnosis including localization of the air, thus facilitating prompt treatment. A case of subdural tension pneumocephalus after cranial operation under the impression of bifrontal subdural hygroma is presented.

Oligodendroglioma constitutes about 4% of all gliomas. The usual symptoms of oligodendrogliomas are seizures, focal neurologic deficits, and increased intracranial pressure. They usually present with a gradual onset of symptoms and slow progression. The apopletic symptom due to sudden tumor bleeding is rare. The author review literatures and present a case of oligodendroglioma initially manifested as ventricular hemorrhage after head injury.

This is a report of 13 cases of surgically corrected ruptured aneurysm of the aortic sinus of Valsaha. The simultaneous trans-venous and trans-arterial catheterization and cineangiogram are the best diagnostic procedures. In 12 cases, the aneurysm originated from the right coronary sinus and only one from the noncoronary sinus. Eleven aneurysms ruptured into the right ventricle and 2 into the right atrium. Eight cases were associated with ventricular septa1 defect and 5 with aortic regurgitation. In three cases the Hancock porcine valve replacement was done. There was no surgical mortality.

To clarify the exact role of endomyocardial biopsy in the diagnosis and monitoring of adriamycin-induced cardiotoxicity and to observe the actual relationship between pathologic changes and cardiac dysfunction, a cross-sectional clinical study was conducted. Echocardiography was used to evaluate cardiac dysfunction in 18 patients who had received chemotherapy including adriamycin(mean dose : 410mg/m2 of B.S.A.) without clinical evidence of congestive heart failure, and in 19 normal controls. Six patients receiving adriamycin underwent 7 transfemoral endomyocardial biopsy procedures, and the specimens were evaluated by light and electron microscopy for evidence of drug-related cardiotoxicity. Indexes of cardiac systolic function obtained by M-mode echocardiography(left ventricular dimension, excursion of interventricular septum and left ventricular posterior wall, shortening fraction and ejection fracton) did not show any statistically significant difference between patients who received adriamycin and normal controls. In transmitral flow-velocity curves recorded by Doppler echocardiography with a 2.25MHz probe, the patients showed less E peak velocity and decreased E/A ratio compared with normal controls, which suggests left ventricular diastolic dysfunction in the patients who received adriamycin. All the specimens of the endomyocardial biopsy showed significant pathologic changes of adriamycin indnced cardiotoxicity which was characterized by myofibrillar loss and vacuolization of the cytoplasm. In 2 specimens, pathologic grade was II, while 5 specimens showed pathologic changes of grade III and further chemotherapy with adriamycine was not done in thse 5 cases. From these results it is suggested that pathologic changes precede the clinical onset of congestive cardiomyopathy in the patients receiving adriamycin and left ventricular diastolic dysfunction occurrs before ejection fraction falls to subnormal levels. We conclude that sequential endomyocardial biopsy is absolutely indicated for exact diagnosis and monitoring of adrinamycin-induced cardiotoxicity to prevent the development of irreversible and often fatal cardiomyopathy.
