Chronic kidney disease (CKD)-mineral and bone disorder (CKD-MBD) is a common complication of CKD, often accompanied by extra-skeletal calcification in adult patients. As increased vascular calcification is predicted to increase cardiovascular mortality and morbidity, the revised Kidney Disease: Improving Global Outcomes guidelines recommend avoiding calcium-containing phosphate chelators. However, extra-skeletal calcification is less commonly noticed in pediatric patients. Here, we report our experience of such a complication in pediatric patients receiving maintenance peritoneal dialysis. Extra-skeletal calcification was noticed at the corneas, pelvic cavity, and soft tissues of the lower leg in 4 out of 32 patients on maintenance peritoneal dialysis. These patients experienced the aggravation of extra-skeletal calcifications during peritoneal dialysis, and 2 of them underwent excisional operations. It is required to monitor extra-skeletal calcifications in children on kidney replacement therapy.

Rectal injury is seen in 1-2% of all pelvic fractures, and lower urinary tract injury occurs in up to 7%. These injuries are rare, but if missed, can lead to a severe septic response. Rectal injury may be suspected by the presence of gross blood on digital rectal examination. However, this classic sign is not always present on physical examination. If an Antero-Posterior Compression type pelvic fracture is seen, we should consider the possibility of rectal and lower urinary tract injury. It is important to define the anatomic location of the rectal injury as it relates to the peritoneal reflection. Trauma to the intraperitoneal rectum should be managed as a colonic injury. Extraperitoneal rectal injury should be managed with fecal diversion regardless of primary repair. We present the case of a 46-year-old man who was referred to our hospital following a major trauma to the pelvis in a pedestrian accident.

만성폐쇄성 폐질환을 동반한 노인환자에서 척추마취하에서 치골상부 전립선 절제술을 시행하는 도중 척추마취와는 무관한 것으로 사료되는 원인 불명의 경련 발작 및 혈압강하가 초래된 환자가 발생하였기에 그 원인을 규명하고 문헌적 고찰과 함께 보고하는 바이다.

Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

Regulatory B cells, also well-known as IL-10-producing B cells, play a role in the suppression of inflammatory responses. However, the epigenetic modulation of regulatory B cells is largely unknown. Recent studies showed that the bromodomain and extra-terminal domain (BET) protein inhibitor JQ1 controls the expression of various genes involving cell proliferation and cell cycle. However, the role of BET proteins on development of regulatory B cells is not reported. In this study, JQ1 potently suppressed IL-10 expression and secretion in murine splenic and peritoneal B cells. While bromodomain-containing protein 4 (BRD4) was associated with $NF-{\kappa}B$ on IL-10 promoter region by LPS stimulation, JQ1 interfered the interaction of BRD4 with $NF-{\kappa}B$ on IL-10 promoter. In summary, BRD4 is essential for toll like receptor 4 (TLR4)-mediated IL-10 expression, suggesting JQ1 could be a potential candidate in regulating IL-10-producing regulatory B cells in cancer.

Background: There are limited data in the literature related to concomitant genital or extra-genital organ pathologies in patients with borderline ovarian tumors (BOTs). The aim of this study was to evaluate our experience with 183 patients to draw attention to the accompanying organ pathologies with BOTs. Materials and Methods: One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013 were evaluated retrospectively. Data related to age, tumor histology, lesion side, disease stage, accompanying incidental ipsilateral and/or contralateral ovarian pathologies, treatment approaches, and follow-up periods were investigated. Incidental gynecologic and non-gynecologic concomitant organ pathologies were also recorded. Results: The mean age at diagnosis was 40.6 years (range: 17-78). Ninety-five patients (51%) were ${\leq}40$ years. A hundred and forty-seven patients (80%) were at stage IA of the disease. The most common type of BOT was serous in histology. Non-invasive tumor implants were diagnosed in 4% and uterine involvement was found 2% among patients who underwent hysterectomies. There were 12 patients with positive peritoneal washings. Only 17 and 84 patients respectively had concomitant ipsilateral and concomitant contralateral incidental ovarian pathologies. The most common type of uterine, appendicular and omental pathologies were chronic cervicitis, lymphoid hyperplasia and chronic inflammatory reaction. Conclusions: According to our findings most of accompanying pathologies for BOT are benign in nature. Nevertheless, there were additional malignant diseases necessitating further therapy. We emphasize the importance of the evaluation of all abdominal organs during surgery.

목 적 : 본 연구에서는 정량적 자가방사선사진법을 이용하여 비정형 항정신병 약물의 하나인 risperidone 이 백서 뇌의 신경수용체에 어떻게 작용하는지를 알아보고자 하였다. 대상 및 방법 : 급성투여군은 백서 30마리를 6군으로 나누어 0, 0.1, 0.25, 0.5, 1, 2mg/kg의 risperidone을 복강내 투여하고 2시간후에 단두하였고, 만성투여군은 0, 0.1, 1mg/kg의 risperidone을 21일간 복강내 투여후 단두하여 정량적자가 방사선사진법으로 $5-HT_2$과 $D_2$ 수용체에 대한 [$^3H$]spiperone 결합을 측정함으로써, 선조체, 측좌핵, 전두엽피질 각각의 $5-HT_2$과 $D_2$ 수용체의 분포변화를 측정하고 투여량에 따른 수용체의 영향을 ANOVA 검정으로 분석하였다. 결 과 : 급성투여군에서 $5-HT_2$ 수용체는 전두엽 피질에서 risperidone 투여후 0.1-2mg/kg의 투여 범위전체에서 [$^3H$]spiperone 결합이 대조군에 비하여 32% 이하로 감소하여 통계적으로 유의한 차이를 보였으며, 선조체와 측좌핵의 피질하 수용체에서는 거의 결합을 보이지 않았다. $D_2$ 수용체는 risperidone 투여량의 증가에 따라 선조체와 측좌핵의 [$^3H$]spiperone 결합이 감소하였으며, 1-2mg/kg의 투여량을 준 경우에는 대조군에 비해 57% 이하로 감소하여 통계적으로 유의한 차이를 보였다. 만성투여군에서는 피질의 $5-HT_2$ 수용체가 대조군에 비하여 저용량투여군과 고용량투여군에서 각각 51%와 46%로 감소하였다. 결론 : Risperidone은 $D_2$ 수용체를 약하게 차단하며 $D_2$ 수용체에 영향을 주는 양보다 적은 양을 투여해도 $5-HT_2$ 수용체를 차단하는 효과를 보임으로써 $5-HT_2$ 수용체에 강력히 작용하는 비정형 항정신병 약물임을 알 수 있었다.
