Objective To analyze the preoperative diagnostic clues to ovarian pregnancy (OP). Methods This study conducted a retrospective chart review of 23 patients with OP and 46 patients with tubal pregnancy (TP) from October 1, 2003 to September 31, 2016 in Hanyang University Hospital. Results There were no significant differences in demographic and clinical characteristics between the two groups. The presence of an ectopic gestational sac and hemoperitoneum was significantly higher in the TP group (13.0% vs. 95.7%, P=0.000; 13.0% vs. 54.3%, P=0.001, respectively) in preoperative ultrasonogram. The OP group had more ruptured ectopic gestational sacs than the TP group (73.9% vs. 45.7%, P=0.039) in surgical findings. Conclusion For the patients in whom a gestational sac is not detected in the uterus or the fallopian tubes, it is important to be aware of the possibility of OP and rupture of an ovarian gestational sac to promote early diagnosis and surgical intervention.

The hypopharyngeal gland (HPG) of the honeybee worker produces royal jelly (RJ) and has a developmental cycle closely related to the division of labor. In this study, we investigated to compare the HPG acini diameter of differently aged worker bees with high royal jelly producing colony (HRC) or less producing colony (LRC). Additionally, we also evaluated whether the fresh weight of the head is a reliable indicator of the developmental status of HPG. The HRC showed a significantly higher RJ production about two-times as compared with those of the LRC. We measured the HG-diameters on days 1, 3, 6, 9, 12, 15. The microscopic analysis revealed that the acini size of the HRC was significantly larger than the LRC. In addition, the acini diameter of HRC was 15% longer than the LRC on the first day after emerging. It was shown that the fastest development during 3 days which is preparing for nurse the brood. The HPG acini diameters increased in both colonies in a similar fashion until day 12 and then decreased. We also compared the fresh head weight of the experimental colonies, differences were similar to the development of HPG. Therefore, high royal jelly production may have a positive correlation between HPG acini size and the fresh head weight.

Retroperitoneal inclusion cysts are uncommon mesothelium-lined cysts seen in the pelvis of reproductive-age women. It presents as a pelvic mass or with pelvic pain and may be misdiagnosed as an ovarian malignancy. Although benign, local recurrences are common, often requiring repeated surgeries. We report a case of retroperitoneal inclusion cysts, which was diagnosed clinically as benign multilocular cyst of ovary; however, it turned out to be retroperitoneal mesothelial inclusion cyst on histopathology. A 55-year-old postmenopausal woman referred to our outpatient department with intermittent lower abdominal pain. Results of routine blood investigation and CA-125 were within normal limits. A pelvic MRI showed a cystic ovarian tumor, approximately 7 cm in diameter with numerous septated small cysts. We performed a laparoscopic surgery on April 19, 2016. First, we removed extensive adhesions on pelvic wall. After confirming no abnormalities in both ovaries, we opened the peritoneum to investigate retroperitoneal space. There was a cystic multiloculted mass firmly attached to the right ureter and the pouch of Douglas. The lesion was friable and to avoid rupture of the cyst and spillage of the cystic fluid, meticulous care was taken. Complete resection of the lesion was performed. Postoperative recovery was good and the histopathology showed benign cystic mesothelial lesion. We present this case along with a video clip.

Objective : Retrospective analysis to compare the effect and complication of epidural patient-controlled analgesia (epidural PCA) with intravenous patient-controlled analgesia (IV PCA) for the treatment of the post-operative pain after posterior lumbar instrumented fusion. Methods : Sixty patients who underwent posterior lumbar instrumented fusion for degenerative lumbar disease at our institution from September 2007 to January 2008 were enrolled in this study. Out of sixty patients, thirty patients received IV PCA group and thirty patients received epidural PCA group. The pain scale was measured by the visual analogue scale (VAS) score. Results : There were no significant difference between IV PCA group and epidural PCA group on the PCA related complications (p=0.7168). Ten patients in IV PCA group and six patients in epidural PCA group showed PCA related complications. Also, there were no significant differences in reduction of VAS score between two groups on postoperative 2 hours (p=0.9618) and 6 hours (p=0.0744). However, postoperative 12 hours, 24 hours and 48 hours showed the significant differences as mean of reduction of VAS score (p=0.0069, 0.0165, 0.0058 respectively). Conclusion : The epidural PCA is more effective method to control the post-operative pain than IV PCA after 12 hours of spinal fusion operation. However, during the first twelve hours after operation, there were no differences between IV PCA and epidural PCA.
The Effects of Legal and Extra-legal Factors on Sentencing among Korean Marijuana Offenders

본 연구는 마리화나 관련 마약 범죄자들을 대상으로 양형에 영향을 미치는 요인들을 검토한 것으로서, 범죄의 심각성, 범죄경력과 같은 법적 요인(legal factor)과 범죄사회적 맥락(criminal social context), 사회통합(community integration), 인구학적 특성과 같은 법률 외적 요인(extra-legal factor)이 마약범죄자들의 양형에 어떠한 영향을 주는지 경험적으로 분석하였다. 자료의 출처는 1997년부터 2001년까지 전국의 10개 지방검찰청에서 처리한 987명의 마리화나사범에 대한 수사 및 재판기록 조사이다. 마리화나 범죄자의 양형에 영향을 미치는 요인들은 문헌연구에 근거하여 법적 요인과 법률 외적 요인으로 분류되었으며, 다변량 회귀분석을 통해 그 효과가 검증되었다. 분석결과, 법적 요인으로는 공범수, 범죄의 유형, 범행의 지속성, 마약동종전과여부가 유의미한 영향을 미치는 것으로 확인되었고, 법률 외적 요인으로는 법정에서의 태도와 사회계층이 양형에 실질적 영향력을 갖는 것으로 나타났다. 요컨대, 마리화나 사범의 양형에 있어서는 법적인 요소가 법외적 요소에 비하여 상대적으로 더 많은 영향력을 행사하고 있는 것으로 보인다. 이러한 결과의 배경에는 한국의 대마약 범죄정책이 갖는 무관용 원칙(zero tolerance)이 반영된 것으로도 해석된다. 이와 관련한 정책적 함의는 본문에서 더욱 자세히 논해진다. Unlike active researches on marijuana offense in the U.S., there is no research that have developed characteristics of marijuana offenders or examined the predictive factors on sentencing decision. The purpose of this study is to draw the general characteristics of marijuana offenders and to investigate significant factors on sentencing outcomes in Korea. The present study empirically tested the effect of legal factor such as crime severity and prior criminal history and extra-legal factors such as the criminal social context, possibility of the community integration and demographic factors on the decision. Using the 987 official records of marijuana offenders disposed by ten district public prosecutors' offices in six large cities from 1997 to 2001, we examined the effect of legal and extra-legal factors on marijuana sentencing throughout the OLS regression. The results is showing that legal variables have more powerful impact on the marijuana sentence than extra-legal variables. However, an attitude in the courtroom and social class showed the significant effect on the decision as extra-legal variables. The reason of the strong power of extra-legal variables could be found in the zero tolerance policy for drug related offenses in Korea. Additional implications for research and policy are discussed.
