Schistosomiasis in patients in the Sultanate of Oman.

Background: Following an intensive public health eradication program, the focus of schistosomiasis mansoni at Salalah in Southern Oman (the only focus of schistosomiasis in Oman), appeared to have been eradicated in 1994. Since the vector snails for Schistosoma mansoni (and also for S. haematobium) were widely endemic in freshwater springs at Salalah, and reintroduction of infection (or introduction in the case of S.

Human immunodeficiency virus type 1 infection in Oman: antiretroviral therapy and frequencies of drug resistance mutations.

Highly active antiretroviral therapy (HAART), consisting mainly of two nucleoside reverse transcriptase inhibitors (NRTIs) and one protease inhibitor (PI), is offered to < 10% of HIV-infected subjects in Oman. The aims of the present study were to determine the frequency of resistance-associated mutations in these patients, and to assess the contribution of drug resistance to treatment outcome. Among 29 patients on HAART for > or =6 months, virological, failure was observed in 27 (93%).

Subclinical pulmonary haemorrhage causing a restrictive lung defect in three siblings with a unique urticarial vasculitis syndrome.

Three siblings with urticarial vasculitis syndrome (UVS) are described. All had restrictive lung function abnormalities caused by subclinical pulmonary haemorrhage. The latter was suspected after finding haemosiderin-laden macrophages and a friable bronchial mucosa during elective bronchopulmonary alveolar lavage (BAL).

Q Fever in human and livestock populations in Oman.

In 2000, Q fever was documented for the first time in the Sultanate of Oman in two patients, one with chronic pericarditis and the other with acute pneumonia. In 2001, a study of a randomly selected group of 102 adult patients from different provinces in northern Oman, presenting to the University Hospital in Muscat with unrelated conditions (e.g.

First report of Q fever in Oman.

Although serologic evidence suggests the presence of Q fever in humans and animals in Saudi Arabia and the United Arab Emirates, acute Q fever has not been reported on the Arabian Peninsula. We report the first two cases of acute Q fever in Oman.
