Background: We investigated surgical outcomes after the surgical repair of cor triatriatum sinister (CTS). Methods: Thirty-two consecutive patients who underwent surgical repair of CTS from 1993 through 2020 were included in this study. The morphological characteristics, clinical features, and surgical outcomes were described and analyzed. Results: The median age and body weight at operation were 9 months (interquartile range [IQR], 3–238 months) and 7.5 kg (IQR, 5.8–49.6 kg), respectively. There were 16 males (50%). According to the modified Lucas classification, type IA (classical CTS) was most common (n=20, 62.5%). Atrial septal defect was associated in 22 patients (68.8%) and anomalous pulmonary venous return in 8 patients (25%). Pulmonary hypertension was preoperatively suspected with a high probability in 18 patients (56.3%). There was 1 early death (3.1%) after emergent membrane excision and hybrid palliation in a high-risk hypoplastic left heart syndrome patient. There were no late deaths. The overall survival rate was 96.9% at 15 years post-repair. No early survivors required reoperation during follow-up. Most survivors (31 of 32 patients, 96.9%) were in New York Heart Association functional class I at a median follow-up of 74 months (IQR, 39–195 months). At the latest echocardiography performed at a median of 42 months (IQR, 6–112 months) after repair, no residual lesion was observed except in 1 patient who had moderate pulmonary hypertension (mean pulmonary arterial pressure of 36 mm Hg). Conclusion: Surgical repair of cor triatriatum could be performed safely and effectively with an extremely low risk of recurrence.

Spinal ependymomas originate in the ependymal lining and grow rather slowly which allows them to reach considerable size and length. The great majority of primary tumors of the cauda equina are ependymomas and show a rather marked predilection for the male. Histologically ependymomas are benign but metastasis and anaplasia have been reported. The basic architectural structures of the ependymoma are the ependymal rosettes and pseudo-rosettes. Intradural spinal arteriovenous malformations are relatively rare lesions and found only at autopsy or incidentally during surgical operations before the advent of investigative procedure. Development of myelography and spinal angiography have shown that vascular malformations of the spinal cord are not rare. Male is more predominant than female. The etiology and pathophysiological mechanisms are uncertain but many authors have believed that congenital, trauma, inflammations, tumoral processes, vasculitis and abnormal posture are influenced on A-V malformations of the spinal cord. No reports have been noticed about giant ependymomas of the cauda equina combined with spinal A-V malformations. We have experienced a case of giant ependymomas of the cauda equina associated with thoracic intradural spinal A-V malformations in forty-two year-old male and reviewed the literatures.

Facial psoriasis is a chronic condition, which has considerable resistance to the usual topical or systemic therapies. To date, previous studies have demonstrated the efficacy of pulsed dye laser (PDL) for the treatment of psoriasis, except facial psoriasis. A 38-year-old man who had 4-year history of psoriasis has visited our clinic for his resistant facial psoriasis. He was treated with total 2 PDL sessions at 2-week intervals on his forehead. The lesion showed clinical improvement in its size, erythema and scales. Herein, we report a case of facial psoriasis treated with pulsed dye laser.

In this paper we consider the sample size problem in linear regression model. The results in simple linear regression depend on the correlation between the variables. More generally we show that the sample size can be solved in multiple regression using standard technique and that the sample size depends on the significance level. Using joint confidence interval for regression coefficients we get the solution of the sample size problem.

Pseudoaneurysms of the cystic artery and cholecystoduodenal fistula formation are rare complications of cholecystitis and either may result from an inflammatory process in the abdomen. A 68-year-old man admitted with acute cholecystitis subsequently developed massive upper gastrointestinal (GI) bleeding. Abdominal computed tomography showed acute calculous cholecystitis and hemobilia secondary to bleeding from the cystic artery. Angiography suggested a ruptured pseudoaneurysm of the cystic artery. Upper GI endoscopy showed a deep active ulcer with an opening that was suspected to be that of a fistula at the duodenal bulb. The patient was managed successfully with multimodality treatment that included embolization followed by elective laparoscopic cholecystectomy. Presently, there is no clear consensus regarding the clinical management of this disease. We have been able to confirm various clinical features, diagnoses, and treatments of this disease through a literature review. A multidisciplinary approach through interagency/interdepartmental collaboration is necessary for better management of this disease. (Korean J Helicobacte r Up Gastrointest Res 2018;18:135-140)
회귀직선에서 우산형 대립가설에 대한 평행성의 점근 분포무관 검정법

우산형 대립가설에 대한 회귀직선의 평행성을 검정하는 점근 분포무관 검정법을 제안하고, 제안된 검정통계량의 점근 분포를 포함한 점근적 성질들을 연구하고자 한다. 기존의 Kim과 Lim(1994)의 검정법과의 비교 연구를 통하여 제안된 검정법이 우수함을 보였다. An asymptotically distribution-free procedure is proposed for paralelism of krefression lines aganist umbrella alternatives. Asympototic properties arediscussed, and comparative results relative to Kim and Lim(1994)'s tests show that our precedure os generally more powerful.
