Free radicals are highly cytotoxic to the heart and are involved in ischemia/reperfusion injury. In this study, we tested the ability of taurine to neutralize the deleterious effects of free radicals generated ex vivo and in vitro. Taurine was added at a concentration of 0.1 mM to the drinking water of experimental rats during 6 months. The animal hearts(More)
A retrospective study of 27 cases of umbilical pilonidal sinus (UPNS) was conducted at the Central Military Hospital of Beirut between 1987 and 1991. In this study a simple conservative surgical technique is described by removing the dead hair and the cotton like dirt as an outpatient procedure without need for anaesthesia or hospitalization. There were 26(More)
Incidence of various Hodgkin (HL) and non-Hodgkin lymphoma (NHL) subtypes and association with viruses in Lebanon are not known. We undertook a nationwide study of 272 patients diagnosed with lymphoma in 2007. HL comprised 32.7 % (n = 89) of cases while NHL represented 67.3 % (n = 183). Consistent with the literature, nodular sclerosis was the most(More)
BACKGROUND Radiofrequency energy is being used more and more frequently in orthopaedics, mainly in the treatment of bone tumors. We postulated that radiofrequency ablation may produce growth plate lesions similar to those observed in the bone and conducted this study to see whether radiofrequency may be used as a technique for producing epiphysiodesis.

The cardiovascular effects of mild and overt thyroid disease include a vast array of pathological changes. As well, thyroid replacement therapy has been suggested for preserving cardiac function. However, the influence of thyroid hormones on cardiac remodeling has not been thoroughly investigated at the molecular and cellular levels. The purpose of this(More)
Malignant struma ovarii is an extremely rare tumor. Two new cases are described and current perspectives provided. Both cases are examples of the mixed form of the disease, and both were treated by surgery alone. One patient underwent total hysterectomy and bilateral salpingooophorectomy; the other had unilateral salpingo-oophorectomy. Both patients(More)
BACKGROUND Differences in epidemiology of kidney disease across the Middle East may arise from variations in indication for biopsy, environmental exposure and socio-economic status. The Lebanese population is composed of different ethnicities, with distinct ancestry and religion, enabling comparison of their effect on the prevalence of kidney disease within(More)
Brain natriuretic peptide (BNP) binds to three types of natriuretic peptide receptors, NPR-A, -B and -C (NPRs). The expression shape of BNP and NPRs seems to be an important modulator factor in the pathogenesis of cardiac hypertrophy. The aim of this study was to evaluate the expression of NPRs in an animal model of pressure overload hypertrophy. Left(More)
Two cases of eosinophilic gastroenteritis (EGE) are reported. One recovered spontaneously, the other relapsed after bowel resection. Comments outline the immunological processes. They relate EGE to the hypereosinophilic syndrome (HES) and other collagenous diseases. Bowel resection is discouraged in favor of more conservative treatment.
