Behcets disease is a chronic systemic disease of unknown etiology, which is characterized by the recurrent orogenital ulcers, eye involvement and skin manifestations. In addition to the major symptoms, it includes arthritis, vasculitis, neurologic manifestations and gastrointestinal lesions. We report a case of Behcets disease associated with intestinal ulcers. The patient, a 45-year-old female, who had been treated under the diagnosis of Behcets disease for 4 years, presented with swallowing difficulty, vaginal discharge and persistent right lower abdominal pain. Colonoscopic examination showed multiple ulcers on the ileocecal region which is reported as the most common site of gastrointestinal Behcets disease. Gastrointestinal evaluation can be useful in diagnosis of Behcets disease, especially in a patient with gastrointestinal symptoms.

PURPOSE: To evaluate the diagnostic efficacy and complications of ultrasound-guided percutaneous renal biopsy using automatic biopsy gun in patients with pediatric diffuse renal disease. MATERIALS and METHODS: Using an 18G automatic biopsy gun, biopsies were performed on 97 pediatric patients with clinically suspicious diffuse renal disease. The acquired tissue specimens were analyzed by photomicroscopy, immunofluorescence, and electron microscopy to support the diagnosis. In the 97 biopsies, the success of the histologic diagnosis, number of glomeruli, and complication rates were retrospectively evaluated by analyzing the variable exams and clinical records. RESULTS: Adequate tissue for histologic diagnosis was obtained in 91 of 97 biopsies (94%) and the mean number of glomeruli was 9.6. Complications such as minute pain, gross hematuria, and small perirenal hematoma presented in 22 of the 97 biopsies (23%), all of which either improved within 5-72 hours or did not need specific treatment. CONCLUSION: Ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun is an effective and safe method for the histologic diagnosis of pediatric diffuse renal disease without any major complication.

OBJECTIVE: The purpose of this study was to evaluate the MR spectrum and MR cholangiographic imaging findings of clonorchiasis. MATERIALS AND METHODS: We reviewed 26 patients with confirmed clonorchiasis by either stool tests (n=24) or surgery (n=2). MR imaging was performed on a 1.5 T system (GE Medical Systems, Milwaukee, WI) with a torso coil. Axial T1-and T2-weighted, gadolinium-enhanced dynamic images and MR cholangiography were obtained. Image analyses were used to identify abnormalities of the intrahepatic and extrahepatic bile ducts and the presence of hepatobiliary malignancy. All MR examinations were reviewed by the consensus of two abdominal radiologists. RESULT: Intrahepatic bile duct abnormalities were seen in 23 (89%) of the 26 patients. The most common finding was mild dilatation of the intrahepatic bile duct which was found in 21 (81%). "Too many intrahepatic ducts" were found in 16 (62%), wall enhancement and thickening in 21 (81%) and filling defects and ductal stricture in the intrahepatic bile duct in 6 (24%) and 3 (12%) patients, respectively. Extrahepatic ductal dilation was found in 5 (19%) and 9 (35%) revealed hepatobiliary malignancy. CONCLUSION: MR imaging revealed various findings of clonorchiasis, including dilatation, wall enhancement, stricture of the intrahepatic ducts and filling defect within the intrahepatic bile duct.

There are a number of published reports aimed at clarifying the effect of hormonal contracept -ives upon the quantity and quality of breast milk during postpartum and lactation periods. As to the volume of milk produced by breast feeding mothers, many authors seem to have agreed on a decrease as an established pattern in the periods following regular administration of oral contraceptives containing estrogen in varying dosage. The quality of milk following administration of hormonal contraceptives, however, remsins a controversial issue. Korea's experience in oral contraceptive is rather a brief one, but use of Eugynon has been widespread and frequent since this hormonal contraceptive was introduced into the national program in 1967. The authors have reviewed the potential significance of data concerning regular use of an oral contraceptive as affecting lactation, and have sought to clarify the interrelationship between the administration of Eugynon and quantity and quality of breast milk from mothers contracepting. with Eugynon in different periods following confinement. A total of 85 women, who were at different periods following deliveries, have been divided into, two groups, one comprising 28 women regularly taking oral pills and the other (57 women) not resorting to hormonal contraceptives if they were contracepting at all. 1. Milk Volume. In view of the possible influence of suckling on the amount of milk produced, efforts were made in this study to standardize the technique by extracting breastmilk by applying manual pressures on one side of the maw-nae, While the nipple on the other side was being sucked by the mother's own baby. The effetct of an exogenic ovarian hormone on the quantity as well as quality of breastmilk is generally understood to be inapparent until the drug is administered to women whose milk secreting function has been normalized. ") In the present study, it was observed that the decrease in the ammount of milk obtained from mothers in the periods following the 4th cycle of oral contraceptives or thereafter has turned out to be statistically insignificant. This result conforms i.u the findings by Tubari and others. It is assumed that it takes at lest 2 to 3 cycles of use before mammary glands are functionally adjusted to the use of exogenic hormonal contraceptives. 2. Specific Gravity and Composition of Milk There was no noticeable change in the protein and chloride content following continuous administration of ore.l contraceptives, while meaningful changes were observed in fat (increase) and calcium (decrease up to the 5th cycle use) contents. Also, there was a rather significant decrease in the specific gravity in the period following administration of the first cycle of the oral contraceptive. The findings from the present study partially conforms the results published by Ramadan and others, who reported that little change was noticed in the contents of total solids. ash, chlorides and lactose in the breast milk of women who had taken 4 cycles of ovosiston, although in our study lactose was not measured. Ramaden, however, reported that fat content did increase in the same milk, as in our study. A definitive conclusion, however, could not be made unless measures are taken to rule out the physiological changes of the maternal body affecting the composition of milks.

Intentional delay of aftercoming siblings in multiple gestation is an infrequent occurrence in obstetrics. After delivery of an immature twin, conventional treatment calls for induction and delivery of the aftercoming sibling. However, several case reports have documented the feasibility of an expectant management. And also, as in our case, an aggressive treatment consisting of cerclage, tocolysis, and broad-spectrum antibiotics has been shown to prolong pregnancy. We experienced an unavoidable delivery of a nonviable first twin after premature rupture of membranes at 16 weeks' of gestation. The placenta was left undisturbed. Twin B was confirmed to be alive within the intact second sac. Tocolysis was started and cervical cerclage was done directly after delivery of twin A. Pregnancy was successfully prolonged, which enabled the second fetus to remain in utero and grow for another 145 days. To our knowledge, this was the longest interval between deliveries in a twin pregnancy reported in the literature. A healthy 3,050 gm male was delivered by cesarean section at 37 weeks' of gestation. Below we present this case in detail and discussed with respect to the aggressive approach undertaken to prolong gestation.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.

PURPOSE: The purpose of this study was to evaluate the usefulness of diffusion tensor imaging (DTI) in the grading of gliomas. MATERIALS AND METHODS: DTI was performed in 24 patients with histologically confirmed brain gliomas. After placing the regions of interest (ROI) in the tumor center, tumor border, white matter adjacent to tumor, and normal-appearing white matter (NAWM) of the contralateral hemisphere, the FA values were measured. The size of the ROI was found to be 61 ml. In addition, the FA ratios were calculated for the ROIs in relation to the NAWM of the contralateral hemisphere. RESULTS: The mean FA ratios in patients with grade II gliomas were 0.348 for the tumor center, 0.564 for the tumor border, and 0.897 for the white matter adjacent to the tumor. For patients with grade III gliomas, the mean FA values were 0.247, 0.346, 0.782, respectively. Further, for patients with grade IV gliomas, the mean FA values were 0.204, 0.226, 0.336, respectively. The differences in the FA ratios between the grade II and III tumors were significant in the tumor center and tumor border (p = 0.005, p = 0.002, respectively). Moreover, the differences in the FA ratios between the grade III and IV tumors were significant in the tumor border and white matter adjacent to the tumor (p = 0.004, p = 0.004, respectively). CONCLUSION: DTI is a non-invasive imaging modality that may provide valuable information for the pre-operative grading of gliomas.

Neonatal Hemangioendothelioma (HE) is the most common type of hepatic vascular tumor that presents in infancy. HE generally undergo spontaneous regression within a year, but it may become symptomatic and be associated with life-threatening complications including congestive heart failure, consumptive coagulopathy and hepatic rupture. We report five cases of neonatal hepatic HE with brief review of the literatures. The report include a case of HE associated with AV malformation complicated by congestive heart failure who was successfully treated by hepatic artery embolization, a case of HE associated with transposition of great artery (TGA), and three cases of asymptomatic HE with spontaneous involution.
