With the widespread use of fertility medications and techniques of in vitro fertilization, multiple gestation has become epidemic in modern obstetric practice. Delivery of the initial fetus in a multiple gestation usually is followed by delivery of the subsequent fetus or fetuses shortly thereafter. However in rare circumstances, the delivery is delayed for days due to disappearance of uterine contraction after delivery of the first fetus. When uterine activity ceases after the delivery of the first neonate, a policy of nonintervention may be considered in case of an immature or very premature delivery, in order to achieve a gestational age for the remaining fetus(es) more compatible with neonatal survival. We report a case of twin gestation with prolongation of the delivery interval between the twins for 46 days.

Aims: CT hepatic volumetry is currently accepted as the most reliable method for preoperative assumption of the graft weight for living donor liver transplantation. However, the estimated value from CT volumetry can be deviated from real graft weight due to several factors including the difference between the preoperative assumptive and the actual hepatectomy planes. It may be worthwhile to determine how much each factor contributes to the error of CT volumetry. Thus, the purpose of this study was to determine the resection plane-dependent error of CT volumetry for right hepatic lobe in live liver donors. Methods: Forty-six live liver donors underwent CT scans ≤2 months before the liver procurement and within postoperative day 7. CT volumetry was performed by two radiologists in consensus using a computer-aided liver volumetry software. Prospective CT volumetry (VP) was measured with assumptive hepatectomy plane. Retrospective liver volume (VR) was measured using actual plane determined by comparing preoperative and postoperative CT scans. Compared with intraoperatively measured weight (W), errors of percentage (%) VP and VR were evaluated. Plane-dependent error of VP was defined as absolute difference between VP and VR. % plane-dependent error was defined as follow:|VP-VR|/W·100. Results: Mean VP, VR, and W were 761.9 mL, 755.0 mL, and 696.9g. Mean and % errors of VP were 73.3 mL and 10.7%. Mean error and % error of VR were 64.4 mL and 9.3%. Mean plane-dependent error of VP was 32.4 mL. Mean % plane-dependent error was 4.7%. The plane-dependent error of VP exceeded 10% of W in approximately 10% of the subjects in our study. Conclusions: There is approximately 5% plane-dependent error for VP at CT volumetry. However, even with correction of plane-dependent error, error of VR is still approximately 9% compared with W.

Background/Aims: Computed tomography (CT) hepatic volumetry is currently accepted as the most reliable method for preoperative estimation of graft weight in living donor liver transplantation (LDLT). However, several factors can cause inaccuracies in CT volumetry compared to real graft weight. The purpose of this study was to determine the frequency and degree of resection plane-dependent error in CT volumetry of the right hepatic lobe in LDLT. Methods: Forty-six living liver donors underwent CT before donor surgery and on postoperative day 7. Prospective CT volumetry (V< SUB >P< /SUB >) was measured via the assumptive hepatectomy plane. Retrospective liver volume (V< SUB >R< /SUB >) was measured using the actual plane by comparing preoperative and postoperative CT. Compared with intraoperatively measured weight (W), errors in percentage (%) V< SUB >P< /SUB > and V< SUB >R< /SUB > were evaluated. Plane-dependent error in V< SUB >P< /SUB > was defined as the absolute difference between V< SUB >P< /SUB > and V< SUB >R< /SUB >. % plane-dependent error was defined as follows: |V< SUB >P< /SUB >-V< SUB >R< /SUB >|/W·100. Results: Mean V< SUB >P< /SUB >, V< SUB >R< /SUB >, and W were 761.9 mL, 755.0 mL, and 696.9 g. Mean and % errors in V< SUB >P< /SUB > were 73.3 mL and 10.7%. Mean error and % error in V< SUB >R< /SUB > were 64.4 mL and 9.3%. Mean plane-dependent error in V< SUB >P< /SUB > was 32.4 mL. Mean % planedependent error was 4.7%. Plane-dependent error in V< SUB >P< /SUB > exceeded 10% of W in approximately 10% of the subjects in our study. Conclusions: There was approximately 5% plane-dependent error in liver V< SUB >P< /SUB > on CT volumetry. Plane-dependent error in V< SUB >P< /SUB > exceeded 10% of W in approximately 10% of LDLT donors in our study. This error should be considered, especially when CT volumetry is performed by a less experienced operator who is not well acquainted with the donor hepatectomy plane. (Clin Mol Hepatol 2018;24:54-60)
CASE REPORT : A Case of Langerhans Cell Histiocytosis Manifested as a Suprasellar Mass
( Ju Young Yoon ),( Byung Kiu Park ),( Heon Yoo ),( Sang Hyun Lee ),( Eun Kyung Hong ),( Weon Seo Park ),( Young Joo Kwon ),( Jong Hyung Yoon ),( Hyeon Jin Park ) 대한뇌종양학회 대한신경종양학회 2016 Brain Tumor Research and Treatment Vol.4 No.1
Langerhans cell histiocytosis (LCH) has diverse clinical manifestations, including intracranial mass lesions. We report a case of LCH that manifested as a suprasellar mass, and initially misdiagnosed as a germ cell tumor. A 29-year-old woman presented with polyuria, polydipsia and amenorrhea. Laboratory findings revealed hypopituitarism with central diabetes insipidus, and a suprasellar mass and a pineal mass were observed on magnetic resonance imaging. Under the clinical impression of a germ cell tumor, the patient was treated with germ cell tumor chemotherapy (cisplatin and etoposide) and radiation therapy without biopsy. After initial shrinkage of the lesions, further growth of the tumor was observed and a biopsy was performed. The histopathology revealed LCH. After chemotherapy according to the LCH III protocol, the tumor disappeared. She is on regular follow up for 5 years without relapse. The present findings indicate that LCH should be included in the differential diagnosis of a suprasellar mass, even in adults, especially when it manifests with diabetes insipidus. This case also underscores the importance of a histopathologic diagnosis in patients with suprasellar tumors before the initiation of a specific therapy, even if the clinical findings are highly suggestive of a specific diagnosis.

위암발증의 원인을 밝히기 위하여 설문조사를 통하여 강원도 화천군에 거주하는 주민들의 일반사항, 생활습관 및 영양섭취실태와, ELISA법으로 Helicobacter pylori 감염률을 조사하였다. 조사 대상자는 40∼69세까지의 지역주민 169명으로 남자 79명, 여자 90명이었으며 그 결과는 다음과 같다. 조사 대상자의 학력은 65.7%가 초등학교 이하였으며, 월수입은 60%가 50만원 이하였다. 대상자의 62.7%가 농업에 종사하였고 자녀수는 64.3%가 3∼5명이었으며 대상자의 34.5%가 흡연을 하고 있었고 68.4%가 음주를 한다고 대답하였다. 대상자의 전체 평균신장은 156.7㎝로 여자는 150.1㎝, 남자는 164.4㎝ 이었다. 평균체중은 61.1㎏으로 여자의 체중은 57㎏, 남자는 65.7㎏이었으며 BMI는 전체 평균 25.5%로 여자는 24.8%, 남자는 20.1%이었다. Helicobacter pylori의 감염률은 전체 조사대상자의 66.3%이었으며, 여자의 67.7%, 남자의 64.6%가 감염되었고 연령별로는 40대의 70%, 50대의 62.2%, 60대의 69.4%가 각각 감염된 것으로 나타났다. 일상 생활 요인에 따른 Helicobacter pylori의 감염률은 흡연의 정도가 심하고 학력이 낮으며 월수입이 낮을수록 높은 경향을 보였다. Helicobacter pylori의 감염여부에 따라 감염자와 비감염자의 영양섭취량을 조사해 본 결과 비감염자는 감염자와 비교해서 에너지, 총단백질, 동물성 단백질, 칼슘, 비타민 C 섭취량이 높은 경향을 보였으며 철분과 niacin의 섭취량은 낮은 경향을 보였다. To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status, we surveyed 169 persons, 90 females and 79 males, aged 40∼69 years from June 7 to June 14, 1997, in Whachon area, Kang-Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation, life-style and food intake on Helicobacter pylori infection. Helicobacter pylori status was evaluated using an enzyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 66.3% of total subjects, namely, 67.7% of female and 64.6% of male and its prevalence increased with smoking, low education level and low monthly income. Energy, total protein, calcium and vitamin C intakes in the negative Helicobacter pylori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the Helicobacter pylori negative group than in the positive group.
