A 67-year-old man with a history of chronic obstructive pulmonary disease (COPD) underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for staging of gastric cancer. The projection images of F-18 FDG PET/CT showed intensely increased F-18 FDG uptake in the anterior neck, chest wall, and upper abdomen. We suspected distant metastases of cervical lymph nodes, ribs, and peritoneum in gastric canter. However, the transaxial images of F-18 FDG PET/CT showed abnormal F-18 FDG uptake in scalene muscles of anterior neck, intercostal muscles of chest wall, and diaphragm of upper abdomen. Patients with COPD use respiratory muscles extensively on the resting condition. These excessive physiologic use of respiratory muscles causes increased F-18 FDG uptake as a result of increased glucose metabolism. The F-18 FDG uptake in respiratory muscles of gastric cancer patient with COPD mimicked distant metastases in cervical lymph nodes, ribs, and peritoneum.

Purpose: Peritoneal carcinomatosis (PC) has a dismal prognosis and is occasionally encountered during initial exploration in patients with gastric cancer. The clinicopathological characteristics and survival were analyzed in patients with gastric cancer and PC. Materials and Methods: Among 2,083 gastric cancer patients who received surgery at the department of surgery, Hanyang University Hospital from 1992 to 2009, 130 patients revealed PC. Ten patients who were lost during follow-up were excluded. The remaining 120 patients were divided into three groups according to the type of surgery. The degree of PC was classified into P1(to the adjacent peritoneum) and P2 (to the distant peritoneum). Various other clinicopathological factors were analyzed using univariate and multivariatec survival analyses. Results: Systemic chemotherapy (SC), type of surgery, lymph node dissection, degree of PC, and presence of ascites were significant prognostic factors. However, age, gender, resection of PC, and Borrmann type were not significant prognostic factors. In a multivariate analysis, SC and the degree of PC were independent prognostic factors. The survival benefit of SC was significant without reference to the type of surgery or degree of PC. Conclusions: A gastrectomy should be considered feasible in patients with gastric cancer and PC. The independent favorable prognostic factors were SC and a low degree of PC. SC improved the prognosis regardless of operation type and degree of PC.

BACKGROUND/OBJECTIVES: Abundant consumption of seaweeds in the diet is epidemiologically linked to the reduction in risk of developing cancer. In larger cases, however, identification of particular seaweeds that are accountable for these effects is still lacking, hindering the recognition of competent dietary-based chemo preventive approaches. The aim of this research was to establish the antiproliferative potency and angiosuppressive mode of action of Stoechospermum marginatum seaweed methanolic extract using various experimental models. MATERIALS/METHODS: Among the 15 seaweeds screened for antiproliferative activity against Ehrlich ascites tumor (EAT) cell line, Stoechospermum marginatum extract (SME) was found to be the most promising. Therefore, it was further investigated for its anti-proliferative activity in-vitro against choriocarcinoma (BeWo) and non-transformed Human embryonic kidney (HEK 293) cells, and for its anti-migratory/tube formation activity against HUVEC cells in-vitro. Subsequently, the angiosuppressive activity of S. marginatum was established by inhibition of angiogenesis in in-vivo (peritoneal angiogenesis and chorioallantoic membrane assay) and ex-vivo (rat cornea assay) models. RESULTS: Most brown seaweed extracts inhibited the proliferation of EAT cells, while green and red seaweed extracts were much less effective. According to the results, SME selectively inhibited proliferation of BeWo cells in-vitro in a dose-dependent manner, but had a lesser effect on HEK 293 cells. SME also suppressed the migration and tube formation of HUVEC cells in-vitro. In addition, SME was able to suppress VEGF-induced angiogenesis in the chorio allantoic membrane, rat cornea, and tumor induced angiogenesis in the peritoneum of EAT bearing mice. A decrease in the microvessel density count and CD31 antigen staining of treated mice peritoneum provided further evidence of its angiosuppressive activity. CONCLUSIONS: Altogether, the data underline that VEGF mediated angiogenesis is the target for the angiosuppressive action of SME and could potentially be useful in cancer prevention or treatment involving stimulated angiogenesis.

Objective : In vitro proapoptotic effect of Hangbaek-Tang (HBT) has been documented by one of us. In the present study, we aimed to demonstrate in vivo effect of HBT on tumor growth. Methods : In vitro selective cytotoxicity of HBT was examined by enumeration of viable cell numbers using BC3A mouse leukemic cells and normal spleen cells. In vivo effect of HBT (25 and 50 mg/mouse) on tumor growth was assayed using BC3A cells innoculated subcutaneously in the flank. Annexin-V apoptosis assay and PI staining was performed to determine the effective serum factor in HBT-treated mice. Leukocyte recruitment into peritoneum were analyzed by microscopy with a stained cytosmear of peritoneal lavage fluid. Results : HBT exhibited in vitro selective cytotoxicity to leukemic cells and did not show any toxicity on immune organs. In vivo i.p. administration of HBT induced significant reduction in tumor growth but not complete regression. Sera obtained from HBT-treated mice strongly inhibited BC3A cell growth in vitro and were revealed to markedly enhance apoptosis and accompanying cell death, when compared to those from PBS-treated mice. Abundant extravasation of leukocytes, especially neutrophils, into peritoneum was observed in HBT-treated mice. Conclusions : HBT causes leukemic, BC3A cell death in vivo via apoptosis as well as in vitro, for which functional involvement of leukocytes is suggested.

Endometriosis is a disease characterized by implants of endometrial tissue outside the uterine cavity and is strongly associated with infertility. Focal adhesion of endometrial tissue to the peritoneum is an indication of incipient endometriosis. In this study, we examined the effect of various cytokines that are known to be involved in the pathology of endometriosis on endometrial cell adhesion. Among the investigated cytokines, transforming growth factor-${\beta}1$ ($TGF-{\beta}1$) increased adhesion of endometrial cells to the mesothelium through induction of ${\alpha}2-6$ sialylation. The expression levels of ${\beta}$-galactoside ${\alpha}2-6$ sialyltransferase (ST6Gal) 1 and ST6Gal2 were increased through activation of $TGF-{\beta}RI/SMAD2/3$ signaling in endometrial cells. In addition, we discovered that terminal sialic acid glycan epitopes of endometrial cells engage with sialic acid-binding immunoglobulin-like lectin-9 expressed on mesothelial cell surfaces. Interestingly, in an in vivo mouse endometriosis model, inhibition of endogenous sialic acid binding by a $NeuAc{\alpha}2-6Gal{\beta}1$-4GlcNAc injection diminished $TGF-{\beta}1$-induced formation of endometriosis lesions. Based on these results, we suggest that increased sialylation of endometrial cells by $TGF-{\beta}1$ promotes the attachment of endometrium to the peritoneum, encouraging endometriosis outbreaks.

In conventional percutaneous disc surgery, introducing instruments into disc space starts by inserting a guide needle into the triangular working zone. However, landing the guide needle tip on the annular window is a challenging step in endoscopic discectomy. Surgeons tend to repeat the needling procedure to reach an optimal position on the annular target. Obturator guiding technique is a modification of standard endoscopic lumbar discectomy, in which, obturator is used to access triangular working zone instead of a guide needle. Obturator guiding technique provides more vivid feedback and easy manipulation. This technique decreases the steps of inserting instruments and takes safer route from the peritoneum.

Traumatic abdominal wall hernia is a rare condition that can follow any blunt trauma to the abdomen. Generally there has been an increase in the incidence of blunt abdominal trauma, although the case of traumatic abdominal wall hernias are rare. Probably due to the elasticity of the abdominal wall for resisting the shear forces generated by a traumatic impacts. In this case, we are reporting 1 rare case, diagnosed as an abdominal wall hernia associated with herniation of bowel loops due to blunt trauma without intra-abdominal injury including peritoneum.

This study was carried out to compare the efficacy of carboxymethyl chitosan fabric (CMCF) with that of the combination of low molecular weight heparin (LMWH) and CMCF for the prevention of postoperative adhesions in the rat. Adhesions were induced by suturing both the ileal serosa and peritoneum scraped until petechial bleeding occurred. CMCF were sutured between two surfaces, and LMWH were instilled intraperitoneally immediately before closure of the peritoneomuscular layer. The adhesions were blindly assessed 2 weeks later by using a tensiometer. The mean tensile strength(Newton) of formed adhesions was $2.59{\pm}0.85$ in control group, $2.10{\pm}0.75$ in the CMCF group and $1.53{\pm}0.44$ in the CMCF+LMWH group. The most favorable prevention against adhesion was achieved in the CMCF+LMWH group. Therefore, we could conclude that CMCF+LMWH were effective in prevention against postoperative adhesion in the rat.

Torsion of the wandering spleen is a rare condition especially in children. Unfortunately, splenectomy was the advocated treatment of choice for wandering spleen in many children up to 1985 in spite of the well-known possibility of overwhelming postsplenectomy sepsis. Because of the conclusive evidence of the vital function of the spleen in infection, indication of splenectomy have been revised and more attention has been paid to preserving the spleen where possible. We are presented a girl with splenic torsion, seen as a migratory abdominal mass and intermittent vague abdominal pain. Splenopexy by fixation of the spleen to the diaphragm and posterolateral peritoneum and the use of Avitene in the splenic bed was successfully performed. Complete fixation of the spleen was confirmed by ultrasound a year after this procedure was carried out. The clinical presentation, etiology, diagnostic procedures and management are discussed also.
