Nonsurgical endoscopic or percutaneous dilatation and insertion of an endoprosthesis is the treatment of choice in the majority of patiens with incurabie malignant biliary obsturction. But these palliative treatment of extrahepatic cholestasis with an endoscopic or percutaneous biliary endoprosthesis is limited by clogging. One of the factors thought to be of importance is the diameter of the stent. So in order to avoid being limited by the size of the instrumentation channel of the endoscope, expandable stents have been developed. Wallstent is braided in the form of a tubular mesh from surgical grade stainless alloy. This prosthesis is geometrically stable, pliable and self expanding. Its elastic properties are such that its diameter can be substantially reduced by moderate elongation. The stent is constrainded on a small diameter delivery catheter(total outside diameter: 9 French). During the implantation procedure the final position of the partially released endoprosthesis can be adjusted by gradual removal of the delivery catheter. If full expansion to 30 French occurs, the stent will be shortened by approximately 30% to their normal length range between 34-102mm. Now in this article we report a new method for endoscopic retrograde placement of biliary Wallstent in a patient with obsturctive jaundice due to periampullary choangiocacrcinoma.

BACKGROUND: EMLA cream is a eutectic mixture of lidocaine and prilocaine and has excellent anesthetic effect on tympanic membrane but histologic influence on tympanic membrane is uncertain. OBJECTIVE: To investigate its histologic effects on tympanic membrane. MATERIALS AND METHODS: 18 Sprague-Dawly rats were divided into 6 groups. Each group was treated with application of EMLA cream into external ear canal and then were sacrificed at 4 hours, 24 hours, 3 days, 7 days, and 14 days after application of the agents. RESULTS: 1) Transmission electron microscopy revealed partial loss of epithelial cell at 4 hours after application of the agents. 2) The specimen showed damaged cells in the epidermal layer and partial loss of basement membrane at 24 hours after application of the agents. 3) At 1 week after application of the agents epidermal layer and inner epithelium with connective tissue predominated. Thus the fibrous layer represent only 1/3 of total drum thickness. In the basal layers widened intercellular spaces were noted. 4) At 2 weeks after application of the agents newly formed connective tissue was found at fibrous layer and numerous fibroblasts were noted at inner epithelial layer. but overall histologic changes of the drum were not significant and healing processes was noted. CONCLUSION: EMLA cream has less histopathologic effects on tympanic membrane, and early recovery process occurred.

The purpose of the study is to minimize the incidence of glaucoma and ocular hypertension caused by using corticosteroids during induction chemotherapy for acute lymphoblastic leukemia in children. We have periodically observed the intraocular pressure and the variation of C / D ratio of two 7 years old boys with chemotherapy in our pediatric department. We observed the increase in intraocular pressure using applanation tonometer, and we managed by beta- blockers, carbonic anhydrase inhibitor and etc. Increased intraocular pressure has been normalized after chemotherapy. The frequency of occurrence of the ocular hypertension and glaucoma can be controlled with the quantity of corticosteroids used.

Intratesticular varicocele is a rare entity and refers to a dilated intratesticular vein radiating from the mediastinum testis into the testicular parenchyma. A 22-year-old man was admitted to our hospital with left testicular pain. On physical examination, a grade III varicocele was noted on the left side. Gray-scale ultrasound and color Doppler ultrasound examinations revealed intratesticular and extratesticular varicocele. The patient underwent spermatic vein ligation by open modified Palomo varicocelectomy.

In vitro ethylene-diamine-tetra-acetic acid (EDTA) dependent satellitism and phagocytosis of platelets by neutrophils have been considered to be rare phenomena. It is associated with pseudothrombocytopenia, abnormal histogram of platelets and pseudoleukocytosis on complete blood cell count (CBC) by automated blood cell counter, but these findings are not found in heparinized or sodium citrated blood. It has no clinical significance such as bleeding tendency or abnormal platelet function. EDTA dependent platelet satellitosis and phagocytosis must be differentiated from true thrombocytopenia. We report a case of EDTA dependent platelet phagocytosis by neutrophils in a 68 year-old male patient who was diagnosed as mycosis fungoides. His EDTA blood smear showed frequent phagocytosis of platelets by neutrophils and occasional platelet satellitism. The bood cell counts were within normal limits without pseudothrombocytopenia. Phagocytized platelets were confirmed by immunohistochemistry using GpIIb/IIIa antibody and transmission electron micrographs.

PURPOSE: Colon cancer shows various genetic alterations in its development and progression. Recently, microsatellite instability (MSI) has been related to a novel mechanism of carcinogenesis, and might be a useful prognostic factor in several gastrointestinal malignancies. The loss of heterozygosity (LOH) is known to be related with the allelic loss of various tumor suppressor genes, however, MSI, which has been found to result from an erroneous DNA mismatch repair system, has been known to be involved in the carcinogenesis of hereditary non-polyposis colon cancers and some aspects of sporadic colorectal cancers. In this study, the status of MSI was examined in sporadic colon cancers, and its correlation with various clinico-pathological parameters investigated. METHODS: Fifty sporadic colorectal cancers, treated by surgery alone, were analyzed for the presence of MSI using microsatellite markers, and tumor and normal DNA, obtained from formalin-fixed paraffin-embedded archival tissues. MSIs were examined at the BAT25, BAT26, D2S123, D5S346 and D17S250 loci, as recommended in the 1997 NIH International Workshop on Microsatellite Instabilities and RER phenotypes. RESULTS: MSI was detected in 11 cases (22%), and was more frequently detected in the non-metastatic adenocarcinoma and Astler-Coller stages A+B1+C1 groups than in the metastatic and B2+C2+D groups. Also, there were no metastatic cases in the MSI-high group, where more than 3 loci had MSI. LOH was detected in three of the recommended markers, and was observed in 17 cases (34%). LOH was more highly detected in the metastatic and B2+C2+D groups, but there was no correlation with the clinico-pathological parameters. However, no LOH-positive cases were found in the MSI-positive group. CONCLUSION: These results suggest that MSI may be partially involved in colorectal carcinogenesis and the metastasis mechanism. Also, the clinical use of the MSI status may help in determining the prognosis of colorectal cancer patients.

von Gierke disease (type Ia glycogen storage disease) is an inherited disease associated with accumulation of glycogen in the liver, kidney, intestine and erythrocytes due to the defect of glucose-6-phosphatase activity. Hepatomegaly, doll face, anemia, bleeding tendency and increased susceptability to infection are common features observed during infancy. Hypoglycemia especially fasting hypoglycemia is typical metabolic derangement in this disease, followed by metabolic acidosis, lactic acidemia, hyperlipidemia, hyperuricemia, and platelets dysfunction. We experienced a case of von Gierke disease in 6 month-old boy with doll face, hepatomegaly, fasting hypoglycemia, acidosis, anemia, hyperlipidemia, hyperuricemia, and acetonuria. Diagnosis was confirmed by light- and electron microscopic examination of liver biopsy specimen, which revealed hepatocytes filled with dense pools of glycogen and many lipid droplets. Cornstarch dietary therapy for him had favorable responses showing improvement of hypoglycemia, other metabolic derangements, and regression of hepatomegaly.

Background: Prevailing insulin regimens for glycemic control in hospitalized patients have changed over time. We aimed to determine whether the current basal-bolus insulin (BBI) regimen is superior to the previous insulin regimen, mainly comprising split-mixed insulin therapy. Methods: This was a single tertiary center, retrospective observational study that included non-critically ill patients with type 2 diabetes mellitus who were treated with split-mixed insulin regimens from 2004 to 2007 (period 1) and with BBI from 2008 to 2018 (period 2). Patients from each period were analyzed after propensity score matching. The mean difference in glucose levels and the achievement of fasting and preprandial glycemic targets by day 6 of admission were assessed. The total daily insulin dose, incidence of hypoglycemia, and length of hospital stay were also evaluated. Results: Among 244 patients from each period, both fasting glucose (estimated mean±standard error, 147.4±3.1 mg/dL vs. 129.4±3.2 mg/dL, P<0.001, day 6) and preprandial glucose (177.7±2.8 mg/dL vs. 152.8±2.8 mg/dL, P<0.001, day 6) were lower in period 2 than in period 1. By day 6 of hospital admission, 42.6% and 67.2% of patients achieved a preprandial glycemic target of <140 mg/dL in periods 1 and 2, respectively (relative risk, 2.00; 95% confidence interval, 1.54 to 2.59), without an increased incidence of hypoglycemia. Length of stay was shorter in period 2 (10.23±0.26 days vs. 8.70±0.26 days, P<0.001). Conclusion BBI improved glycemic control in a more efficacious manner than a split-mixed insulin regimen without increasing the risk of hypoglycemia in a hospital setting.
