Authors have quantitated the T cell and T subsets(T and T cell) in the per- ipheral blood of 16 patients with alopecia areata and 16 normal healthy controls. The results are as follows: 1. The mean values of the T cell in total patient group(54,6+7.9g) and AAP group(5,3. 1+8. 1%) showed staticstially significant decrease when it compared with the mean value of the control group(64.6+3.6%) respectively(p<0.005). In ATU group the mean value of the T cell(53. 1+8. 1%) also showed decreasing tendency in comparison with that of control. The mean values of the T cell in total patient group(30.9+8. 9%) RIld AAP group(3'l. 5+8. %) showed statistically significant decrease when it compared with the mean value of the control group(42,6+8.9%) respectively(p<0. 005). In ATU group the mean value of the T< cell(28. 7+10. 9%) also showed decreasing tende- ncy in comparison with that of control. 3. The mean values of the Tr, cell in total patient group(6. 1+2. 2%) and AAP group(5.9+2.4%) showed staticstially significant decrease when it compared with the mean value of the control group(7.9+1.3%) respectively(p(p pl, pgp p25) In ATU group the mean value of the T cell(6. 7+0. 9%) also showed decreasing tendency in comparison with that of control. 4. The mean values of the T/T ratio showed no significant difference between the patient groups(total, AAP, ATU) and control group, respectively. Above data showed that defect of T cell and T subsets may be associated with the pathogenesis of alopecia areata.

The role of the immune system in pathogenesis of skin cancer has been attracted increasing attention in recent years. Some limited studies and observations suggest that altered immune status may be a factor in the initiation and growth of cutaneous malignancies. Authors experienced a typical case of xeroderma pigmentosum in a 6 year-old girl, who has been suffered from hyper and hypopigmented macules on sun-exposed area, photophobia and also noted eroded lesion on the lower lip. The biopsy finding of the hyperpigmented macule showed that of freckle and the finding of actinic cheilitis was observed from the specimen of eroded 1esion on the lower lip. We performed immunologic test and obtained some evidences of immunologic defect; such as decreased numbers of total T cells, T-suppressor cell and B cell in our patient.

Epidermolysis bullosa dystrophica(EBD) is a rare, hereditary and chronic mechanobullous disease characterized by blistering and erosions of the skin in response to even minor trauma. A 5-year old girl visited with a complaint of continuous vesicobullous skin eruptions since birth. On examination, bullae, vesicles, atrophic scars, crusts and ero:ions were scattered on whole body. Loss of finger and toe nails, partial syndactyly of all toe webs and milia on dorsa of feet were noticed. We present a case of EBD that seems to be a recessive type considering the absence of family history with histopathologic and electron microscopic findings.

BACKGROUND: A retrospective study was performed to evaluate postoperative mortality within 30 days following surgery. METHODS: The records of 31,806 patients who received operation under general anesthesia were reviewed. RESULTS: 1) Postoperative deaths were 184 cases, the ratio of which was comprising 0.57% of all surgical operative cases. 2) The highest ratio of the mortality in age group was 51~60 years group which was 24.5%, and in physical status it was ASA class III which was 36.4%. The highest ratio to the mortality rate in postoperative days was 8~30 days which was 45.1%. 3) The most common causes of death was low cardiac output due to heart failure on operating theater, and hypovolemic shock within postoperative 2 days, and intracranial problem within postoperative 7 days, and pulmonary complication within postoperative 30 days. CONCLUSION: We conclude that fatality rate could be decreased by intensive and multidisciplinary care for postoperaive complications as respiratory and renal failure.

This study was performed to evaluate the effects of acute withdrawal of antiepileptic drugs in epileptic patients during continuous BEG monitoring. One hundred sixty-five withdrawals in 134 patients who were candidates for epileptic surgery were included for this study. Clinical features and frequency of seizure were observed after drug withdrawal with daily monitoring of serum drug level. The phases after withdrawal of antiepileptics were divided into phase of therapeutic drug level, phase of falling drug level, and phase of subtherapeutic or undetectable(zero) drug level. There were significant increase in frequency of seizure and seizure of secondary generalization after acute withdrawal of antiepileptic drugs. Number of seizure during the period of drugs withdrawals was not correlated with onset age of epilepsy, duration of epilepsy, duration of medication, and number of administrated antiepiteptic drugs. The number of frequency of seizure before drug withdrawal was correlated with the number of frequency of withdrawal seizure. The number of seizure frequency after carbamazepine withdrawal was significantly higher during the phase of subtherapeutic or zero drug level, and not during phase of rapid falling antiepileptic drug level.

This study was performed to evaluate the usefulness of dermatomal somatosensory evoked potentials(D-SSEP) and segrnental somatosensory evoked potentials(S-SSEP) for the diagnosis of lurnbosacral radiculopathy. D-SSEP and S-SSEP were recorded from 30 healthy controls and 16 patients with lumbosacral radiculopathy(LA radiculopathy: 10 cases, L5: 13 cases, SI: 4 cases) who was diagnosed by clinical findings CT and/or MRI. D-SSEP were abnormal in 40%, 30.7% and 25% of the patients with IA, L5 and Sl radiculopathy respectively and S-SSEP were abnormal in 20%, 38% and 50% of the patients with IA, L5 and Sl radiculopathy respectively. The proportion of abnormal findings in the' patients with L4, L5 and Sl radiculopathy was increased to 50%, 46. 1% and 50% respectively by administering both of D-SSEP and S-SSEP. In conclusion, D-SSEP and S-SSEP are simple and noninvasive test but insensitive studies for diagnosis of lumbosacral radiculopathy. The diagnostic sensitivity could be increased by usmg both of these two studies.

A 66 year old male with a suprarenal pheochromocytoma on the left side was treated preoperatively with oral phenoxybenzamine 20 mg, b. i. d. for 2 weeks. The night before surgery, phenobarbital 100 mg & diazepam 5 mg were given orally. One hour before induction, diazepam 10 mg i. m. was given. Preinduction BP was 210/140 and HR was 130/min. After diazepam 20 mg i. v, BP lowered to 200/130 and HR lowered to 126/min. With commencement of sodium nitroprusside i. v. dripping, a BP of 160/100 and HR of 118 were maintained. Following Thiopental sodium 250 mg i. v., mask induction was started with N2O-O2-Enflurane and pancuronium 4 mg i. v., after 5 minutes, a #8.5 tube was intubated and pindolol 0.16 mg was injected to prevent tachycardia. We maintained a tolerable BP and pulse by repeatedly adding a bolus i. v. injection of phenoxybenzamine 1 to 2 mg during tumor manipulation and removal. No arrhythmia was noted throughout the procedure, except tachycardia. After removal of the tumor, with rapid blood transfusion and fluid infusion plus dopamine i. v. dripping, a tolerable BP and pulse was maintained.

BACKGROUND & OBJECTIVES: It was well known that benign paroxysmal positional vertigo(BPPV) was caused by the involvement of the posterior semicircular canal, but there were a few reports about horizontal canal variant of BPPV. We studied the clinical features electronystagmographic (ENG) findings and the possible mechanism of BPPV of the horizontal canal(HBPPV). METHODS: We examined 10 cases of HBPPV with episodic vertigo and intense horizontal geotropic nystagmus provoked by rotation of the head in a supine position. Six patients underwent ENG and we recorded four patients' nystagmus, provoked by rotating head from extreme lateral, mid and nose-up position to extreme contralateral direction in supine position. RESULTS: All observed horizontal nystagmus beated towards the ground on both sides and were more pronounced when head was rotated to pathological side. In rotating to pathological side, nystagmus had mean latency of 2.6+/-1.8 seconds, peak velocity of slow phase of 66,8+/-19.7 degree/second and mean duration of 24.7+/-3.4 seconds. In rotating to healthy side the nystagmus had 3. 7+/- 2.9, 38.0+/-11.5 and 22.5+/-4. Secondary phase nystagmus occurred in 2 patients and fatigue was observed in 4 patients. The slow phase velocity of nystagmus was relative to the distance of head rotation. The duration of attack is 3 to 17 days(6.9+/-5.2days). Liberatory manuever had relatively a good effect. CONCLUSION: HBPPV represents the origin of horizontal semicircular canal and has a good prognosis Above findings support that mechanism of horizontal BPPV is canalolithiasis.

The previous studies had shown that our society had stigma about epilepsy. These studies were not enough to establish practical and concrete educational program for the general population. This study was carried out to evaluate the knowledge of and attitude toward epilepsy in general population. The subjects consist of the population of 1722 apparently healthy persons who reside in Taegu city and Kyungpook province. The questionnaire consists of 39 items concerning knowledge of epilepsy and 20 items of attitude toward epilepsy and epileptic patients. Seventy percent of respondents answered that epileptics have grand mal seizure as their unique type of seizure. Sixty-eight percent were not confident of drug therapy for epilepsy, and 53% considered that epilepsy is a genetic disorder. The score of negative attitude toward car driving and marriage in epileptics was high. The score of knowledge of epilepsy and of attitude toward epilepsy and epileptics show a significant correlation with age and level of education. Although the group of public servant, teacher and professor had relatively high score in knowledge of epilepsy, they had much more negative attitude toward driving and marriage of epileptics. The group of nurse-teacher had higher knowledge and much more affirmative attitude. It is suggested that an educational program to epilepsy should have special emphasis on the etiology, type of epilepsy and efficacy of medical treatment in epilepsy.
