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.

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.

<P>Terminal differentiation of skin keratinocytes is a vertically directed multi-step process that is tightly controlled by the sequential expression of a variety of genes. To examine the gene expression profile in calcium-induced keratinocyte differentiation, we constructed a normalized cDNA library using mRNA isolated from these calcium-treated keratinocytes. After sequencing about 10,000 clones, we were able to obtain 4,104 independent genes. They consisted of 3,699 annotated genes and 405 expressed sequence tags (ESTs). Some were the genes involved in constituting epidermal structures and others were unknown genes that are probably associated with keratinocytes. In particular, we were able to identify genes located at the chromosome 1q21, the locus for the epidermal differentiation complex, and 19q13.1, another probable locus for epidermal differentiation-related gene clusters. One EST located at the chromosome 19q13.1 showed increased expression by calcium treatment, suggesting a novel candidate gene relevant to keratinocyte differentiation. These results demonstrate the complexity of the transcriptional profile of keratinocytes, providing important clues on which to base further investigations of the molecular events underlying keratinocyte differentiation.</P>
