Spinal epidural emphysema is rare and has been described secondary to following medical intervention, such as lumbar puncture and epidural analgesia, pneumothorax or pneumomediastinum, degenerative disk disease, epidural abscess, and trauma. Rarely, it occurs after chest tube placement. We report a case of spinal epidural emphysema incidentally noted on HRCT after chest tube placement.

OBJECTIVE: Invasive cancer cells penetrate the extracellular matrix(ECM), including basement membrane during the metastatic cascades. Matrix metalloproteinases(MMPs) play a critical role in tumor invasion and metastasis and their activities are regulated by specific tissue inhibitors of metalloproteinase(TIMPs). Aberrant ECM degradation in tumor biology is attributed to an imbalance in local MMP and TIMP activity, resulting in the overexpression or enhanced activation of MMPs or reduced TIMP expression. The aim of this study was to compare the MMP-2 & -9, TIMP-1 & -2 mRNA expression in cervical cancer with those in normal cervix and to investigate that their expression is related to cancer stages and other prognostic factors. METHODS: The normal cervix and cervical cancer tissues were obtained from healthy women(n=14), and the patients with cervical cancer(n=31), respectively. Total RNA was extracted and reverse transcribed into cDNA. The expression of MMP-2 & -9, TIMP-1 & -2 mRNA was examined by quantative competitive PCR(QC PCR) and each results were analyzed by t-test and univariate analysis. RESULTS: The expression of MMP-2, TIMP-1 mRNA in cervical cancer was higher than that in nomal cervix(p<0.05). The TIMP-2 mRNA expression was elevated in cervical cancer while that was not shown in normal cervix. The MMP-9 mRNA expression was not statistically different between normal cervix and cervical cancer(p>0.05). CONCLUSIONS: These results suggested that increased MMP-2, TIMP-1 & -2 mRNA expression is an early event during malignant transformation of cervical cancer.

A pregnane steroid, 3α-hydroxy-pregn-7-ene-6,20-dione (1), was isolated from a Hydractinia-associated Cladosporium sphaerospermum SW67 by repetitive column chromatographic separation and highperformance liquid chromatography (HPLC) purification. The planar structure of 1 was elucidated from the analysis of the spectroscopic data (1D and 2D NMR spectra) and LC-MS data. The absolute configuration of 1 was determined by interpretation of ROESY spectrum of 1, together with the comparison of reported spectroscopic values in previous studies. To the best of our knowledge, this is the first report of the identification of the pregnane scaffold from C. sphaerospermum, a natural source. Compound 1 was evaluated for its effects on lipid metabolism and adipogenesis during adipocyte maturation and showed that compound 1 substantially inhibited lipid accumulation compared to the control. Consistently, the expression of the adipocyte marker gene (Adipsin) was reduced upon incubation with 1. Further, we evaluated the effects of 1 on lipid metabolism by measuring the transcription of lipolytic and lipogenic genes. The expression of the lipolytic gene ATGL was significantly elevated upon exposure to 1 during adipogenesis, whereas the expression of lipogenic genes FASN and SREBP1 was significantly reduced upon treatment with 1. Thus, our findings provide experimental evidence that the steroid derived from Hydractinia-associated C. sphaerospermum SW67 is a potential therapeutic agent for obesity.

Background: Postoperative nausea and vomiting (PONV) refers to nausea and vomiting that occurs within 24-h after surgery or in the post-anesthesia care unit (PACU). Previous studies have reported that the use of remimazolam, a newer benzodiazepine (BDZ) hypnotic, for anesthesia results in less PONV. In this study, we compared the rate of PONV between sevoflurane and remimazolam after general anesthesia. Methods: In this prospective randomized controlled trial, participants aged 20–80 years who underwent elective laparoscopic cholecystectomy or hemicolectomy were randomized to either the remimazolam or sevoflurane group. The primary outcome was PONV incidence for 24-h after surgery. Secondary outcomes comprised of PONV at 30-min post-surgery, postoperative additional antiemetic use, and Quality of Recovery-15 (QOR-15) score at 24-h postoperatively. Results: Forty patients were enrolled in the study. The remimazolam group exhibited significantly lower rates of PONV for 24-h after surgery than did the sevoflurane group (remimazolam group vs. sevoflurane group; 5% vs. 45%, P = 0.003, respectively). The use of dexamethasone, a rescue antiemetic administered within 24 h of surgery, was substantially lower in the remimazolam group than in the sevoflurane group (0% in remimazolam vs. 30% in sevoflurane, P = 0.020). The QOR-15 score at 24-h after surgery showed no significant difference between the two groups. Conclusions Compared to sevoflurane, opting for remimazolam as an intraoperative hypnotic may decrease the incidence of PONV and reduce antiemetic use for 24 h after laparoscopic surgery.

Clearance of a difficult biliary stone can be obtained using various interventional techniques such as endoscopic sphincterotomy followed by endoscopic papillary large balloon dilation, mechanical lithotripsy, peroral cholangioscopy-assisted intraductal electrohydraulic/laser lithotripsy, temporary plastic stent insertion, percutaneous transhepatic cholangioscopy-guided lithotripsy, and extracorporeal shock wave lithotripsy. We hereby describe the successful endoscopic treatment using various currently available interventional techniques in a case with multiple difficult common bile duct stones. Furthermore, we discuss the countermeasures to overcome the hurdles of each procedure.

Peritonitis is one of the major complications of CAPD (continuous ambulatory peritoneal dialysis). Among its causative organisms, vancomycin-resistant enterococcus (VRE) is rare, but serious causative organism, because it is refractory to antibiotics commonly used for CAPD peritonitis. Some drugs such as linezolid and dalfopristin have been introduced for VRE infections nowadays, but reports about usefulness of those drugs in VRE peritonitis are rare. We experienced a case of CAPD peritonitis caused by VRE, which was treated successfully with removal of CAPD catheter and use of linezolid. We report our experience with review of the literature.
