Clinical observations were made on a total 104 cases of spontaneous pneumothorax during the period of 5 years from MAR. 1971 to MAR. 1976 at the Dept. of Chest Surgery, Korea University Medical College. The ratio of male to female cases was 7.4 : 1 in male predominance, and age distribution was 73% of the total cases within the 15-40 age range. There were 56 patients (53.8%) of right sided pneumothorax and 44 patients (42.3%) of left sided pneumothorax, 8 patients presented bilateral spontaneous pneumothorax. The etiologic factors were tuberculous origin in 42.3%, rupture of bullae or blebs in 15.4%, acute pulmonary infection in 3.8%, pulmonary paragonimiasis in 2.9%, cysticercosis 1%, Marfan's syndrome in 1.9%, unknown causes in 32.7%. In all 104 cases, closed chest tube thoracostomy were performed for reexpansion of collapsed lung. In 50 cases of 104 cases, intrapleural instillation of Quinacrine HCl (Atabrine, Winthrop Laboratories, New York, N.Y.) thru the chest tube was used to control of recurrent pneumothorax, and compared observation with 54 cases control group of closed chest tube thoracostomy only. In both groups, 1) cure rates were 63% in control group and 88% in Atabrine group. 2) average duration of inserted chest tube were 5.6 days in control group and 5.7 days in Atabrine group.

A 16-month old boy was referred to our hospital for evaluation of recurrent generalized tonic clonic seizures. Metabolic evaluation revealed significant hyperammonemia ($1,112\;{\mu}g/dl$). Amino acid/acylcarnitine screening using tandem mass spectrometry showed markedly increased plasma levels of citrulline ($1,350\;{\mu}M/l$) with undetectable levels of arginine and arginosuccinic acid. Urinary excretion of citrulline was markedly increased ($38,617\;{\mu}M/g$ creatinine). Brain MRI findings showed diffuse high-signal intensity lesions, that involved gray and white matter in both frontal lobes and insula with edematous changes; these findings were consistent with the acute stage of citrullinemia (CTLN). Mutation analysis of the argininosuccinate synthetase (ASS) gene, in this patient, showed a Gly324Ser mutation in exon 13, and a 67-bp duplication mutation in exon 15 (c.1128-6_1188dup67). The patient was confirmed as having late-onset CTLN1 and treated with anticonvulsants, lactulose enema, protein restricted diet and arginine. Here we describe a case of late-onset CTLN1 in a patient by biochemical analyses and ASS gene mutation confirmation. This is the first report of a Korean patient with late-onset CTLN1 confirmed by ASS gene mutation identification.

Migraine is a neurological disorder characterized by recurrent and disabling severe headaches. Although several anticonvulsant drugs that block voltagedependent $Na^+$ channels are widely used for migraine, far less is known about the therapeutic actions of carbamazepine on migraine. In the present study, therefore, we characterized the effects of carbamazepine on tetrodotoxin-resistant (TTX-R) $Na^+$ channels in acutely isolated rat dural afferent neurons, which were identified by the fluorescent dye DiI. The TTX-R $Na^+$ currents were measured in medium-sized DiIpositive neurons using the whole-cell patch clamp technique in the voltage-clamp mode. While carbamazepine had little effect on the peak amplitude of transient $Na^+$ currents, it strongly inhibited steady-state currents of transient as well as persistent $Na^+$ currents in a concentration-dependent manner. Carbamazepine had only minor effects on the voltage-activation relationship, the voltage-inactivation relationship, and the use-dependent inhibition of TTX-R $Na^+$ channels. However, carbamazepine changed the inactivation kinetics of TTX-R $Na^+$ channels, significantly accelerating the development of inactivation and delaying the recovery from inactivation. In the current-clamp mode, carbamazepine decreased the number of action potentials without changing the action potential threshold. Given that the sensitization of dural afferent neurons by inflammatory mediators triggers acute migraine headaches and that inflammatory mediators potentiate TTX-R $Na^+$ currents, the present results suggest that carbamazepine may be useful for the treatment of migraine headaches.

Peritoneal dialysis (PD) is associated with the development of various complications, such as exit site infection or peritonitis, and rarely, intestinal obstruction in prolonged PD patients with recurrent peritonitis. However, post-colonoscopy acute intestinal obstruction has not been reported in PD patients to date. Herein, we report a case of severe ileus after a colonoscopy without previous episodes of peritonitis in a PD patient. A 51-year-old man undergoing PD for 7 years visited our emergency department due to severe abdominal pain and vomiting after colonoscopic polypectomy. A simple abdominal radiography and abdominal computed tomography showed ileus with collapsed distal ileal loop. A peritoneal dialysate study revealed no evidence of peritonitis. The patient was treated with decompression therapy, and ileus was successfully treated without complications. This case suggests that it is not only necessary to prevent peritonitis, but also important to monitor the development of ileus after colonoscopy in PD patients.

턱관절의 탈구는 과두가 관절와를 벗어나 환자 스스로 원래 위치로 정복하지 못할 때 발생한다. 양측성 전방 탈구가 가장 흔하며 탈구의 빈도와 발생 기간에 따라 급성, 만성, 재발성으로 분류하기도 한다. 턱관절 탈구의 치료법으로 수조작 같은 보존적 방법부터 수술적 접근법까지 다양한 방법들이 있으며 치료법의 선택은 주로 탈구가 발생한 기간에 따라 달라진다. 본 증례를 통해서 수조작을 시행하여 턱관절의 탈구를 성공적으로 치료한 증례와 과두의 정복에 실패했으나 만성적으로 적응된 환자에서 수술적 치료 대신 보철 치료로 교합을 회복시켜준 사례를 소개하고 그 의의에 대해 고찰해보고자 한다.

Purpose: Abdominal cysts of gastrointestinal origin are rare. Their rarity and varied clinical presentations make their pre-operative diagnosis difficult. Methods: Fourteen patients with histological diagnosis of cysts of gastrointestinal origin admitted between 2009 and 2015 were retrospectively analyzed with respect to age, sex, clinical presentation, diagnostic modality, site and type of cyst, management, outcome and follow-up. Results: The mean age at presentation was 4 years and there were six males and eight females. Abdominal pain was the most common presenting symptom. Five patients had an acute presentation-three had distal ileal mesenteric cysts and two had ileal duplication cyst sharing a common wall with ileum. Six patients presented with chronic abdominal pain and lump-three patients had omental cysts and three had mesenteric cysts-two of these in distal ileum and one in sigmoid colon. Two patients presented with antenatally diagnosed palpable abdominal lump. One had a mesenteric cyst of the ileum and the other had a distal ileal duplication cyst which required excision with resection and anastomosis. One patient had an atypical presentation. He was a known case of sickle cell trait and had presented with vague abdominal pain, recurrent cough and multiple episodes of haemoptysis over a period of one year. At laparotomy, gastric duplication cyst was found which was excised completely. Histopathology confirmed the diagnosis. Conclusion: Cysts of gastrointestinal origin are rare and have varied presentation. Surgical excision is the mainstay of treatment. The results and prognosis are good.

Background: Treatment failure in leukemia is due to either pharmacokinetic resistance or cell resistance to drugs. Materials and Methods: Gene expression of multiple drug resistance protein (MDR-1), multidrug resistance-related protein (MRP) and low resistance protein (LRP) was assessed in 45 pediatric ALL cases and 7 healthy controls by real time PCR. The expression was scored as negative, weak, moderate and strong. Results: The male female ratio of cases was 2.75:1 and the mean age was 5.2 years. Some 26/45 (58%) were in standard risk, 17/45(38%) intermediate and 2/45 (4%) in high risk categorie, 42/45 (93%) being B-ALL and recurrent translocations being noted in 5/45 (11.0%). Rapid early response (RER) at day 14 was seen in 37/45 (82.3%) and slow early response (SER) in 8/45 (17.7%) cases. Positive expression of MDR-1, LRP and MRP was noted in 14/45 (31%), 15/45 (33%) and 27/45 (60%) cases and strong expression in 3/14 (21%), 11/27 (40.7%) and 8/15 (53.3%) cases respectively. Dual or more gene positivity was noted in 17/45 (38%) cases. 46.5 % (7/15) of LRP positive cases at day 14 were in RER as compared to 100% (30/30) of LRP negative cases (p<0.05). All 8 (100%) LRP positive cases in SER had strong LRP expression (p=<0.05). Moreover, only 53.3% of LRP positive cases were in haematological remission at day 30 as compared to 100% of LRP negative cases (p=<0.05). Conclusions: Our study indicated that increased LRP expression at diagnosis in pediatric ALL predicts poor response to early treatment and hence can be used as a prognostic marker. However, larger prospective studies with longer follow up are needed, to understand the clinical relevance of drug resistance proteins.
