Alveolar echinococcosis of the liver: correlative color Doppler US, CT, and MRI study.

PURPOSE: To determine and compare the imaging features of hepatic alveolar Echinococcosis using color Doppler US, CT, and MRI. MATERIAL AND METHODS: Abdominal CT and MRI with and without contrast agents and color Doppler US were performed on seven patients with hepatic alveolar Echinococcosis. The lesions were evaluated for location, features of echogenicity, intensity and density, calcification, and vascular, hilar, and perihepatic involvement. The diagnosis was confirmed histopathologically in all patients. RESULTS: Six patients had solitary lesions, and one displayed multiple lesions. The lesions were generally seen as heterogeneous and hyper- or hypoechoic when imaged with color Doppler US, hypodense with CT, and hypointense with MRI, in comparison with the liver parenchyma. Calcification, central necrosis, and small peripheral cysts were observed in six, seven, and four patients, respectively. Vascular flow or contrast enhancement was not observed in any of the cases. A look at the respective advantages of each method reveals that calcification was best rendered visible via CT, small peripheral cysts with T2-weighted MRI, central necrosis with CT and MRI, and perihepatic invasion with multiplanar MRI. Vascular involvement was revealed by all methods. CONCLUSION: Color Doppler US, CT, and MR imaging function extremely well as complementary methods in the diagnosis of HAE. Color Doppler US should be performed in these patients owing to its ability to efficiently detect the disease. Knowledge of imaging characteristics makes it possible to radiologically ascertain an early diagnosis.

Continuous ambulatory peritoneal dialysis.

PURPOSE: To assess complications of continuous ambulatory peritoneal dialysis (CAPD) in uremic patients with and without clinical symptoms by CT peritoneography. MATERIAL AND METHODS: A total of 64 patients with end-stage renal disease and on continuous CAPD were investigated. Twenty-eight had some clinical symptoms, which might be related to the complications of CAPD. Thirty-six patients had no complaints or symptoms due to the dialysis treatment. RESULTS: CT peritoneography revealed various complications including hernias (50%), dialysate leakage (46%), localized fluid collection (4%) and peritoneal adhesions (4%) in the patients who had clinical symptoms that might be related to the dialysis treatment. Moreover, similar complications were found in the asymptomatic patients at a lower rate: hernia (3%), dialysate leakage (17%), peritoneal adhesions (3%) and abdominal wall laxity (3%). Complication detection rate by CT peritoneography was 68% (n=19) in the symptomatic patients and 22% (n=8) in the asymptomatic patients. The number of complications found in each group was significant. CONCLUSION: CT peritoneography was an effective modality in detecting complications from CAPD in patients with and without clinical symptoms.

Imaging of an atypical case of congenital toxoplasmosis.

In this article we describe the cranial computerized tomography findings of an infant with congenital toxoplasmosis, which was performed because she showed an atypical clinical course consisting of meningitis and multiple cerebral abscesses. In this case the cranial computerized tomography allowed the diagnosis of hydrocephalus and multiple cerebral abscesses, and guided the therapeutic approach.

A study of the prevalence of having fractures and the affecting factors in young male adults throughout childhood and adolescence.

Injuries due to accidents in children and adolescents, who are more sensitive to different risk factors in their social and physical environments, play an important part in mortality and morbidity. Fractures are the most commonly seen problems among these injuries. This cross-sectional study was carried out in a two-year vocational military school in Ankara between 1-10 May 2000. All, 2720 students in the school were included and data were collected via a questionnaire distributed to the students. It was found that 418 (17%) out of 2,461 students we could interview had had a fracture. No statistically meaningful relationship was found between the frequency of having fractures and the educational status of the parents or employment status of the mother. However, it was seen that the frequency of fractures increased as the economical status of the parents increased. The high frequency of fractures in childhood and adolescence in young males, and the traditional practice of going to unlicensed and medically untrained adults, and "bonesetters" (27% of those surveyed) are two important findings that should be taken into consideration.
