Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Dignosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

Peptic ulcer disease involves breakdown of the epithelial lining of the stomach or duodenum. Stenosis and associated gastric outlet obstruction is the least frequent complication of peptic ulcer disease. Most cases of stenosis occur because of duodenal or pyloric cannel ulceration. Although etiologies of peptic ulcer disease and the affected patient populations have changed, the most common etiologic factors remain Helicobacter pylori infection and use of non-steroidal anti-inflammatory drugs. In recent years, eradication of H. pylori and the use of proton pump inhibitors have reduced the incidence of complications. Because the predominant cause of gastric outlet obstruction has increasingly been attributed to malignant cancer in recent years, endoscopic examination is important to differentiate benign peptic stenosis from malignant stenosis. Medical treatment such as acid-reducing drugs or H. pylori eradication is the mainstay of treatment. Endoscopic dilation or surgical management may be considered in cases of refractory or recurrent stenosis despite medical treatment. Among the major complications of peptic ulcer disease, this report will provide an overview of peptic ulcer-related stenosis.

Indefinite-for-neoplasia is an expression used to describe lesions in which carcinoma or dysplasia cannot be clearly and conclusively established via biopsy. Gastric indefinite-for-neoplasia may represent a reactive change secondary to inflammation in some patients; however, some lesions are eventually diagnosed as dysplasia or carcinoma. Follow-up endoscopic biopsy is commonly performed in patients with gastric indefinite-for-neoplasia lesions. Nonetheless, patients may undergo resection based on a high index of clinical suspicion for dysplasia or carcinoma based on endoscopic findings. Accurate target biopsies of the lesion and effective communication with pathologists are required to improve diagnostic accuracy and avoid unnecessary re-examinations. It is important to establish endoscopic findings useful in differentiating lesions that require resection. In this review, we describe the approach for the management of indefinite-for-neoplasia lesions detected on gastric mucosal biopsy and the characteristics of lesions that require resection.

Nonpalpable breast abnormalities which require excision and biopsy usually require marker localization. Many of these abnormalities are visible on ultrasound and this imaging technique can be used to guide fine needle aspiration and the placement of a wire marker prior to surgical excision. A non-invasive technique which does not require placement of a wire marker would offer significant advantages, being more pleasant for the patient and less demanding on resources. We attempted to localize 36 nonpalpable breast masses with non-invasive ultrasound marker technique at the department of general surgery, Soon Chun Hyang University Hospital, between January 1994 and February 1995. Cases clearly visible on ultrasound, whether on mammography(15 patients) or not(17 patients), underwent non-invasive ultrasound localization. In all cases the abnormality was easily identified and removed during surgery. The surgical biopsies contained fibroadenoma(19 cases), fibrocystic disease(12 cases), epithelial hyperplasia(1 case), intraductal papilloma(1 case), parasitic disease(1 case) and infiltrating ductal carcinoma(2 cases). The average age was 43 years old.. This non-invasive technique is a simple and accurate method for localizing small ultrasonically visible nonpalpable breast abnormalities, especially in younger female patient with dense breast, though further trials and studies will be attempted.

From 1985 to 1991, we analyzed experiences in the treatment of 37 children with neurogenic bladder who were closely followed up for averaging 25 months. Initial urodynamic study revealed hyperreflexic bladder in 17 patients: 12 with detrusor sphincter dyssynergia. Areflexic bladder was round in 20 patients: 11 with high leak pressure. Among the 17 patients with hyperreflexic bladder. intermittent catheterization had been well performed in 13 patients and in 11 cages of which oral or topical anticholinergics were added Renal function was well preserved and urinary incontinence was improved in 10 of 13 patients and urinary diversion was done in 1 case. In 4 patients that were not treated by intermittent catheterization owing to poor compliances augmentation cystoplasty was performed or to be considered. Four cases of areflexic bladder with high leak pressure had good results with treatment, whereas 4 cases had deterioration of renal function because of poor complianes to treatment. Among 9 cases of areflexic bladder with low leak pressure, 6 cases were treated by intermittent catheterization. In all of which voidine symptoms were improved. The other 3 cases are under observation without any problems except urinary incontinence. As above, we can conclude that preservation of renal function and improvement of urinary incontinence can be achieved with intermittent catheterization and oral or topical anticholinergics in pediatric neurogenic bladder patients and that noninvasive treatment including Crede maneuver may be used in the treatment of patients with areflexic bladder with low leak pressure.

Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. The diagnostic criteria for EoE have changed with our growing knowledge over the past two decades. Esophageal eosinophilia, which responds histologically to a proton pump inhibitor (PPI) is not a distinct disease but a subset of EoE. An endoscopic scoring system that relies on the assessment of exudates, rings, edema, furrows, and strictures is a useful tool for assessing endoscopic severity. PPIs are regarded as safe and effective first-line treatments for EoE. Oral topical corticosteroids or dietary therapy are also options for first-line treatment. Endoscopic dilation is effective for relieving the dysphagia symptoms of a patient with an esophageal stricture.

BACKGROUND: Quality control is important for accurate diagnosis of human immunodeficiency virus (HIV) infection, and proficiency testing with external quality controls is an important part of quality control. This study intended to develop and supply customized external quality controls for HIV antigen/antibody testing fitted with currently used reagents for standardization of HIV infection diagnosis and evaluation of HIV testing competency of laboratories in Korea. METHODS: Serological tests and inactivation were performed on the obtained HIV antibody positive plasma. To manufacture quality controls having the required antibody titers, dilution ratio was searched using VIDAS (bioMérieux, France), Architect (Abbott Laboratories, USA), and Cobas 8000 (Roche Diagnostics, Germany) analyzers. Diluted source plasma was divided into aliquots after filtering. Homogeneity and stability of the produced external quality controls were evaluated. RESULTS: The collected HIV antibody positive plasma was confirmed by Western blot. Dilution ratios for source plasma were produced for each analyzer showing signal-to-cut-off 2–3, 5–7, and 15–16 reactivity. Diluted plasma was made to 1 mL aliquots and total set of 1,500 external quality controls for HIV antigen/antibody were manufactured. Produced controls satisfied the required criteria of homogeneity and showed less than 10% coefficient of variation for stability except negative controls. CONCLUSIONS: Customized external quality controls were developed and qualified for HIV testing reagents used in Korea. Continuous external quality control assessment for HIV tests with controls would be required.

Extramedullary plasmacytoma involves organs outside the bone marrow, but involvement of the pancreas is very rare. We present the imaging findings of extramedullary plasmacytoma of the pancreas in a patient with multiple myeloma. Mixed echogenecity was noted at US, and marked enhancement at CT and MR.
