Recently the use of hydrochloric acid as a toilet disinfectant has become more common, and the risk of its ingestion is though to be increasing. We experienced a case of 67 year-old man who accidentally ingested hydrochloric acid and as a result developed a postprandial epigastric fullness end pain 3 weeks thereafter, The patient underwent an UGI series, fiberoptic gastroscope and abdominal ultrasonography and was found to have a gastric midbody stricture. A total gastreetomy and Roux-en- Y esophagojejunostomy was performed. We report this case with brief review of the literature.

PURPOSE: To evaluate the accuracy of X-ray evaluation in classification, displacement and size of posterior malleolar fragment, comparing with three dimensional computed tomography (3D CT) in trimallelar ankle fractures. MATERIALS AND METHODS: 20 cases of trimalleolar ankle fractures evaluated with preoperative 3D CT, and followed up periods were at least 2 years. All cases were classified according to the Danis-Weber and Lauge-Hansen classification. Displacement and size of posterior malleolar fragment were measured using PACS. The reliability between simple X-ray and 3D CT was evaluated in the Danis-Weber and Lauge-Hansen classification (kappa analysis). The correlation between simple X-ray and 3D CT was evaluated in displacement and size of posterior malleolar fragment (correlation analysis). RESULTS: Degree of agreement of Danis-Weber classification in simple X-ray and 3D CT was 0.700 kappa value, and that of Lauge-Hansen was 0.605 kappa value. Measurement of simple X-ray and 3D CT about displaced status of posterior malleolar fragment showed statistically significant positive linear correlation (p= 0.000), but correlation of measurement of size in simple X-ray and CT was not statistically significant (p=0.102). CONCLUSION: CT or operative field will be more accurate than simple X-ray to select the method of treatment and operation, especially when the displacement and size of posterior malleolar fragment are important to decide.

Embryonic stem cells (ESCs) can be propagated in vitro on feeder layers of mouse STO fibroblast cells. The STO cells secrete several cytokines that are essential for ESCs to maintain their undifferentiated state. In this study, we found significant growth inhibition of mouse ESCs (mESCs) cultured on STO cells infected with adenovirus containing a dominant-negative mutant form of IkappaB (rAd-dnIkappaB). This blockage of the NF-kappaB signal pathway in STO cells led to a significant decrease in [3H]thymidine incorporation and colony formation of mESCs. Expression profile of cytokines secreted from the STO cells revealed an increase in the bone morphogenetic protein4 (BMP4) transcript level in the STO cells infected with adenoviral vector encoding dominant negative IkappaB (rAd-dnIkappaB). These results suggested that the NF-kappaB signaling pathway represses expression of BMP4 in STO feeder cells. Conditioned medium from the rAd-dnIkappaB-infected STO cells also significantly reduced the colony size of mESCs. Addition of BMP4 prevented colony formation of mESCs cultured in the conditioned medium. Our finding suggested that an excess of BMP4 in the conditioned medium also inhibits proliferation of mESCs.

A neurofibroma of the gastrointestinal tract is frequently associated with type 1 neurofibromatosis. A solitary neurofibroma, which refers to a localized neurofibroma occurring in patients without stigmata of neurofibromatosis, can rarely occur in the stomach. The majority of neurofibromas of the stomach remain small and asymptomatic, and are usually found incidentally. Surgical resection is required for symptomatic relief and for confirmation of the diagnosis. Herein, the case of a 68-year-old woman found to have a solitary neurofibroma in the angle of stomach is reported. The patient underwent a laparoscopy assisted distal gastrectomy, with a gastroduodenostomy. The gross, microscopic and immunohistochemical findings were consistent with the diagnosis of a neurofibroma of the stomach.

BACKGROUND: Patients with end-stage renal diseases (ESRD) have an increased risk of sleep problems such as daytime sleepiness, insomnia, restless legs syndrome (RLS), and obstructive sleep apnea syndrome (OSAS). However, presently there is limited data available, particularly in Asia. METHODS: To investigate the prevalence of sleep complaints in ESRD patients, 100 patients at the maintenance hemodialysis (HD) and 100 patients at the continuous ambulatory peritoneal dialysis (CAPD) were surveyed using a specific questionnaire. RESULTS: Patients had a mean age of 50.58+/- 14.03 years, with a mean body mass index (BMI) of 21.8+/-3.5 kg/m2. The mean duration of dialysis was 44.56 +/-49.74 months. Fifty-six percent of the dialysis patients were poor sleepers. Daytime sleepiness occurred in 24% to 34% of the patients, and insomnia occurred in 35% of the patients, while restless legs syndrome was reported in 44% of the patients. The higher BMI group had a lower risk for insomnia when compared to the lower BMI group (OR=0.11, 95% CI=0.03-0.46). The OR of depression for insomnia was 2.8 (95% CI=1.02-7.69). There was no difference in the prevalence of sleep disturbances between the HD and CAPD patients groups. CONCLUSIONS: Complaints of sleep disturbance and daytime somnolence are very common in dialysis patients and likely contribute to the impaired quality of life experienced by many of these patients. Identifying and treating the sleep complaints in dialysis patients could contribute significantly to their quality of life and avoid potential side effects of nonspecific sedatives.

The prevalence of right-sided infective endocarditis is increasing with a growing number of intravenous drug abusers. A case of right-sided endocarditis is reported in a 18-year-old female heroin addict. Tricuspid valve vegetation, septic pulmonary emboli and staphyloccus aureus in blood cultures are noted. During antimicrobial therapy, she developed remittent fever and skin rash due to vancomycin. After a change of the antibiotic to teicoplanin, she was freed from fever and discharged in an improved condition.

BACKGROUND: Leptin has been found to be involved in the regulation of hematopoiesis processes and angiogenesis. Therefore, we investigated the effect of leptin in the proliferation and angiogenesis of peripheral blood (PB)-derived endothelial progenitor cells (EPCs). METHODS: Mononuclear cells were isolated from PB of healthy male volunteers and were cultured in endothelial cell growth medium-2 (EGM-2). After 6 days of culture, cells were treated with 50 ng/mL vascular endothelial growth factor (VEGF) and/or with various concentrations of leptin (10 ng/mL, 100 ng/mL, 1microgram/mL, and 10 microgram/mL) and were further cultured for one week. Proliferation of EPCs was examined by an assay measuring the uptake of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbo cyanine-labeled acetylated LDL (Dil-ac-LDL) and tubule formation on a matrigel. The control group of cells was not treated with VEGF and/or leptin. RESULTS: The number of Dil-ac-LDL labeled-EPCs, tubule formation on matrigel and the number of cells present along tubules were significantly increased in the leptin-treated groups of cells as compared to the control group or VEGF treated group of cells (P<.05). The effect was synergistically increased in the group of cells co-treated with leptin and VEGF. The number of EPCs was increased in a leptin dose-dependent manner that was maximal at a concentration of 1microgram/mL leptin. CONCLUSION: This study shows that leptin increased in vitro proliferation and angiogenesis of EPCs derived from peripheral blood.
