ABSTRACT
The liver is the most commonly involved organ in the body by cystic echinococcosis [CE] secondary to infection with Echinococcus granulosus. In this article, the authors discuss the classification, recent advances in magnetic resonance [MR] imaging for the diagnosis of hepatic CE, and approaches for management of hepatic CE using five therapeutic options that include: antihelminthic chemotherapy, surgery, percutaneous treatment, endoscopic approach, and the "watch and wait" approach
ABSTRACT
This paper attempts to identify some factors associated with extramarital sex by men in the Mbeya region of Tanzania using data from a survey conducted in 2003/2004. The choice of Mbeya region was prompted by the fact that it has been found by previous studies to be one of the regions with the highest HIV prevalence rate in Tanzania. Correlates of extramarital sex that were considered include current age; education; residence; age at first sexual intercourse; age at first marriage and sex before marriage. A bivariate analysis of the survey data; which comprised a sample size of 568 married men aged between 15 and 62 years revealed statistically significant association between extramarital sex with current age; education; age at first intercourse and sex before marriage. The effect of these variables was tested through a multivariate logistic regression analysis and all the four independent variables were found to be statistically significant predictors of extramarital sex in Mbeya region

We present a 76-year-old woman known to have a large right hepatic lobe hydatid cyst which recurred twice after surgical excision. CT-guided percutaneous alcohol ablation was conducted to scleroses the cyst, but the procedure was complicated by parenchyma liver laceration and active arterial hemorrhage from a branch of the right hepatic artery. Bleeding was controlled by both endovascular and surgical interventions. Liver laceration with arterial hemorrhage is a rare not previously reported serious complication of percutaneous treatment of hepatic hydatid cyst that may be potentially life-threatening

Dans les pays developpes; au debut de l'epidemie du VIH; l'incidence des complications decrites comme des urgences etait tres elev e e. Mais l'avenement de nouvelles strategies therapeutiques; a fait considerablement reduire la frequence de ces complications et des consultations qu'elles imposaient en urgence. Par contre; dans les pays en developpement ou les moyens de prise en charge sont encore limites; on constate avec amertume; que les patients continuent d'etre exposes a ces complications graves. Mais a defaut d'etudes; on ignore la place du VIH/SIDA parmi les problemes rencontres chez les patients en situation d'urgence dans ces hopitaux. L'objectif de notre etude etait de decri re les urgences medicales liees a l'infection a VIH chez l'adulte au CHU de Treichville. Il s'agit d'une etude pro s p e c t ive sous fo rme d'enquete de prevalence realisee entre mai 1999 et janvier 2000; dans les unites d'urgences d'infectiologie et de medecine. Ont ete inclus dans l'etude les sujets admis aux urgences ages de plus de 15 ans et ayant accepte de participer a l'enquete en se soumettant au pre-test et a la serologie du VIH. Nous avons recrute 400 patients parmi lesquels 312 etaient infectes par le VIH (78). L' age moyen des patients etait de 35 ans. Le sex - ratio H/F etait de 1. Les motifs de consultation les plus frequents :l'alteration de l'etat general (62); la diarrhee (39;1) et la toux (20;5) ; 54des pathologies avaient une evolution chronique. Les signes physiques etaient l'amaigrissement important (83;6); la fievre (50); la paleur des conjonctives (29); les signes respiratoires (19;2) et la deshydratation (19). Les atteintes organiques les plus frequentes etaient digestives (39;7); neurologiques (24;4) et pulmonaires (20;5) et ont necessite plus d'hospitalisation. Aucun cas de deces n'a ete observe. Les urgences medicales liees a l'infection par le VIH chez l'adulte concernent essentiellement les affe ctions opportunistes. Elles posent le pro bleme de leur prise en charge therapeutique.).

ABSTRACT
More than 40% of solid renal masses are incidentally discovered by ultrasound examinations. Computed tomography [CT] remains the cornerstone investigation for characterization and assessment of the extent of renal tumors, it is complementary to ultrasound. MR imaging is an adjunctive method reserved as a problem-solving technique for indeterminate masses by ultrasound and CT. PET-CT has a great potential role in the staging of renal cancer

In this report the authors describe the imaging features of subacute and chronic radiation enteritis in two patients. Although surgery remains the definitive treatment of complicated chronic radiation enteritis, the potential role of interventional techniques that can be used for management of poor surgical candidates is discussed

The imaging modalities currently used for radiologic detection and characterization of hepatic neoplasms include color Doppler sonography. helical computed tomography [plain. Diphasic enhanced CT], magnetic resonance imaging [plain, gadolinium enhanced MR] radionuclide scintigraphy [Technetium RBC, sulfur-colloid, IDA scan], angiography, and image-guided percutaneous needle biopsy. MR imaging is probably better at characterizing lesions than CT scan, but the latter remains the modality of choice at many institutions due to the speed of acquisition and good contrast resolution inherent in the technique. Each of these modalities is useful, but accurate lesion detection and specific radiologic diagnosis is most often made in many patients with typical imaging features using a combination of examinations rather than with a single modality. In the remaining patients with atypical features, a definitive diagnosis is usually obtained by a needle biopsy. Table I summarizes the typical clinical and imaging Findings of common benign solid liver tumors, with suggested further work-up and management. Future developments will focus on the use of special contrast agents in sonography and MRI for further evaluation and characterization of focal hepatic lesions. Emerging clinical applications of these special contrast agents have shown a promising future role for contrast in hanced sonography and MRI as problem-solving examinations after inconclusive ultrasound and helical CT

Hepatobiliary parasitic diseases are rare in Lebanon. We recently encountered biliary fascioliasis in a Lebanese native. The clinical and laboratory findings were nonspecific. The biliary parasite [Fasciola hepatica] was identified by sonography and confirmed at ERCP that has retrieved the parasite from the common bile duct
