Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnet-attached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

Cystic mesothelioma of the peritoneum is a rare benign neoplasm that occurs predominantly in young to middle-aged women and tends to recur locally. Pelvic viscera is the most common predilection site of cystic mesothelioma. Authors report a case of multicystic mesothelioma of the pelvic pelvic peritoneum. The pelvic ultrasonography showed a large, confluent, and thin-walled multilocular cystic mass occupying the pelvic cavity and lower abdomen. The cystic mass was flattened and elongated. Each cyst of variable size was separated by thin septa and filled with translucent fluid. Cystic mesothelioma should be included in the differential diagnosis of the cystic peritoneal masses, especially in reproductive-aged women.

Computed tomography (CT) seems to be the best imaging modality to diagnose an enterovesical fistula, but is not always able to demonstrate enterovesical fistula itself. In this case report, we present Tc-99m HMPAO white blood cell (WBC) scintigraphic findings of an enterovesical fistula complicating Crohn's disease. A 22 year-old male presented with a one-month history of urinary symptoms such as dysuria, hematuria, and frequency. The patient had intermittent right lower quadrant pain, diarrhea and hematochezia. Enterovesical fistula was highly suggestive in pelvic CT which showed air density in the urinary bladder, but cystoscopy failed to find an opening of the fistula. Tc-99m HMPAO WBC scintigraphy for evaluation of inflammatory bowel disease incidentally demonstrated enterovesical fistular tract. Crohn's disease was later confirmed by histologic examination of the surgical specimen. In our patient, Tc-99m HMPAO WBC imaging was helpful in determining the location of the fistula as well as assessing the disease activity and extent of the Crohn's disease.

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.

A computer program using automatic coding of the diagnosis has been used for report printing as well as data storage and retrieval system at the Department of Pathology, Seoul National University Hospital. Previous surgical pathology files were also computerized by the automatic coding system using personal computer, and 100,000 cases of surgical pathology data during 7 years were computerized at present. The cpmputerized surgical files were counted and listed according to topograph and morphologic diagnosis. It is available to print out the list of a specific diagnosis or to copy the records to a floppy diskette. Collection of cases in surgical pathology files using cpmputerized automatic coding system becomes much convenient and accurate than using stored file cards or log books. In addition, previous biopsy records of the patient are automatically searched during the routine work so that understanding of a patient as a whole is possible through the informations about previous pathologic diagnosis. We confirm that automatic coding methods is the most practical and economic method for computerization of the surgical pathology records.

PURPOSE: Leptin is the product of the ob gene secreted by adipocyte. This study investigated whether leptin concentrations were elevated in obese children and the relationship between leptin concentrations and gender, and age in Korean children. METHODS: We measured serum concentrations of leptin in 124 subjects (10 to 18 years, 62 girls and 62 boys). Height, weight, obesity index, and body mass index were measured in 124 subjects. Radioimmunoassay for serum leptin was performed using Human Leptin RIA Kit. Data analysis was done according to the gender, age and obesity. RESULTS: The mean serum concentration of leptin was 5.3 +/- 4.9 ng/ml. The mean leptin level in girls was 7.6 +/- 5.2ng/ml compared with 2.9 +/- 3.3ng/ml in boys (P<0.001). Leptin concentrations were highly increased during the period of 14 to 17 years in girls. The mean serum concentration of leptin in obese group (obesity index>120%) was 8.7 +/- 6.0 ng/ml compared with 4.8 +/- 4.6ng/ml in non-obese group (P<0.01). Serum leptin concentrations were correlated with the body mass index (Pearsons coefficient r=0.42, P<0.001). When boys and girls with equivalent values of body mass index were compared, there was significant difference between the sexes (P<0.001). CONCLUSION: Serum leptin concentrations were significantly higher in girls and obese children. Increased adipose tissue in children was associated directly with serum leptin concentration. Because leptin concentrations were highly increased during the period of 14 to 17 years in girls, it was speculated that central leptin resistance in developing girls may be necessary for the accumulation of the adipose tissue stores.
