Orbital neuroblastoma is the most common childhood metastatic malignant tumor almost always originating from the adrenal medulla; orbital primary origin is very rare. The authors experenced a case of orbital neuroblastoma. The patient was 3 year old Korean female child who was in apparently good health and no abnormalities noted of physical examminations when she developed ecchymosis of right lower lid. About two week later, she quickly developed a growing mass in the right lower orbital soft tissue. The mass was removed and his topathologically diagnosed as neuroblastoma. Radiotherapy was recommended. About 4 months bter, the patient was readmitted because of recurrence of orbital mass 3t the same site. At surgery, tumor was found invading inner and flooe wall of the orbital bone. The patient died of poor course of the disease, about one year after the onset of symptoms. It was suggested that this case was represented metastatic orbital neuroblastoma on histopathological base, but authors were unable to determine the primary site. A brief review of the related literatures is present.

PURPOSE: The genetic polymorphism and intracellular activity of methylenetetrahydrofolate reductase (MTHFR) and thymidylate synthase (TS) is clinically associated with carcinogenesis and biological therapeutic effect in gastrointestinal malignancies. We aimed to elucidate the susceptibility of gastric cancer according to MTHFR and TS gene polymorphism. METHODS: This study was designed as a hospital-based case-control study in a single institute. The gastric cancer group (n=300) for the study was diagnosed at first time as tubular adenocarcinoma, and the control group (n=100) was diagnosed as no malignancy in the endoscopic biopsy. The genetic polymorphism of TS and MTHFR were confirmed by PCR. RESULTS: The MTHFR mutant type had a more than 2-fold increased risk of developing gastric cancer (RR: 2.341). But, only heterozygote type (677CT) revealed significantly higher susceptibility compared to wild type (RR: 2.581). In TS gene genotype, the mutant genotype rate (2R/3R and 3R/3R) was significantly higher in gastric cancer group compared to control group (P=0.008), and the mutant type had a more than 3-fold increased risk of developing gastric cancer (RR: 3.222). In combined MTHFR and TS, 677CT+2R/3R and 677CT+3R/3R there was more than a 3-fold increased risk rate of developing gastric cancer compared with other combinations (RR, 3.474 in 677CT with 2R/3R; RR, 3.895 in 677CT with 3R/3R). CONCLUSION: This study shows a significant association between the MTHFR and TS polymorphisms and susceptibility to gastric cancer, providing a genetic basis. The polymorphisms study of two genes could be applied as susceptibility markers, clinically, for gastric cancer.

It is generally accepted that 1-3% of all inguinal hernias involve the bladder. However herniation of the bladder deep into the scrotum is rare. We report a case of massive bladder hernia of paraperitoneal type in a 58-year-old male with scrotal pain and palpable scrotal mass. Treatment consisted of partial cystectomy and herniorrhaphy. The postoperative result was good without complications.

PURPOSE: Open adhesiolysis has been the favored approach regarding surgical management of intestinal obstruction. Following the development of laparoscopic devices and necessary surgical techniques, laparoscopic treatment of intestinal obstruction and adhesion has been tried in highly selected cases. Our study was designed to investigate laparoscopic adhesiolysis to treat intestinal obstruction. METHODS: The clinicopathologic data and surgical outcomes of 14 patients who underwent emergency laparoscopy between January 2007 and April 2015 were retrospectively reviewed. RESULTS: Five patients had a history of abdominal surgery, and twelve patients had adhesive intestinal obstruction. The causes of adhesive intestinal obstruction included tuberculous peritonitis, periappendiceal abscess, serosal fibrosis and chronic inflammation of intestine, gastric volvulus by fibrotic band. Two patients had non-adhesive intestinal obstruction, caused by intussusception and small bowel ulcer with stricture. The mean surgical time was 98.5 minutes, with mean blood loss of 35 ml. One case was converted to open surgery (7.1%). The mean postoperative hospital stay was 6.5 days. The mean time to oral intake was 3.4 days. There were no postoperative complications or deaths. CONCLUSION: When the patients are selected carefully in accordance with the guidelines, in our experience laparoscopic adhesiolysis is safe and feasible.

We aimed to identify predictive markers of peri- and postpartum disorders in dairy cows. Data regarding peri- and postpartum disorders, serum metabolites, body condition score (BCS), and rectal temperature, were collected from 227 dairy cows, which were allocated to healthy (n = 57) and diseased (n = 170) groups. Serum non-esterified fatty acid (NEFA) concentration was higher in diseased than healthy cows 4 weeks before (p < 0.01) and immediately after (p = 0.05) calving. Serum alanine aminotransferase (AST) activity was higher (p < 0.05) in diseased than healthy cows 1 and 2 weeks after calving, whereas total cholesterol (TCH) concentration was lower (p < 0.05–0.0001) in diseased cows 4 weeks before, and after calving. BCS was higher (p < 0.05) in diseased than healthy cows 4 weeks before calving, but lower (p < 0.01) in diseased cows 8 weeks after calving. Rectal temperature was higher (p < 0.05–0.01) in diseased than healthy cows between 2 and 14 days postpartum. In conclusion, high serum NEFA and AST concentrations and lower TCH concentration during the peripartum period, and high prepartum BCS and postpartum rectal temperature, could be used as biomarkers to predict the subsequent development of peri- and postpartum disorders.

With advances in target therapy, molecular analysis of tumors is routinely required for treatment decisions in patients with advanced non-small cell lung cancer (NSCLC). Liquid biopsy refers to the sampling and analysis of circulating cell-free tumor DNA (ctDNA) in various body fluids, primarily blood. Because the technique is minimally invasive, liquid biopsies are the future in cancer management. Epidermal growth factor receptor (EGFR) ctDNA tests have been performed in routine clinical practice in advanced NSCLC patients to guide tyrosine kinase inhibitor treatment. In the near future, liquid biopsy will be a crucial prognostic, predictive, and diagnostic method in NSCLC. Here we present the current status and future perspectives of liquid biopsy in NSCLC.

Objective: This study aimed to determine the safety and efficacy of the RKP00156 vaginal tablet, a CDK9 inhibitor, in healthy women and patients with cervical intraepithelial neoplasia grade 2 (CIN2). Methods: We conducted a phase 1/2a clinical trial of RKP00156. In step 1, RKP00156 at a dose of 10, 25, or 50 mg or a placebo tablet was administered transvaginally to 24 healthy women.In step 2, RKP00156 at a dose of 10, 25, or 50 mg or a placebo tablet was administered once daily for 4 weeks in 62 patients with CIN2. The primary endpoints of this trial were the safety of RKP00156 and the change in the human papillomavirus (HPV) viral load. Results: A total of 86 patients were enrolled and randomized. RKP00156 administration did not cause serious drug-associated adverse events (AEs). Although no significant difference in the HPV viral load was found between the experimental and placebo groups, a reduction in the HPV viral load was observed in the 25 mg-dose group (−98.61%; 95% confidence interval=−99.83%, 4.52%; p=0.046) after treatment completion in patients with a high HPV viral load, despite a lack of statistical power. No differences in histologic regression and HPV clearance were observed. Conclusion The safety of RKP00156 was proved with no serious AEs. Although the study did not show any significance in histologic regression and HPV clearance, our findings indicate that RKP00156 may have a possibility of short-term inhibitory effect on HPV replication in patients with higher viral loads.
