Human African trypanosomiasis or sleeping sickness is one of the most important but equally most neglected tropical infections. It is caused by a protozoan, Trypanosoma brucei, which is transmitted to humans through the bite of a tsetse fly (Glossina spp). Patchy distribution of the various vector species confines the disease to some 200 microfoci in sub-Saharan Africa (fig 1). The disease had ...

Research in diagnostic radiology often aims to establish the safety and the accuracy of a new procedure or to compare it with other procedures. Frequently, the diagnostic performance of a test can be summarized by proportions such as accuracy, sensitivity, and specificity. Safety may be reflected by the proportion of patients experiencing unpleasant or adverse effects. The confidence interval i...

We report the case of a heart transplant in which the recipient patient had a total congenital absence of the pericardium. Associated with this, we found a major disproportion between the size of the recipient's mediastinal cavity and the size of the donor's heart. To prevent twisting of the great arteries, we placed the graft on the left diaphragm muscle and beneath the left lung, which result...

To the Editor: Marfan syndrome (MFS) (MIM 154700) is a heritable disorder of connective tissue characterised by excessive height and limb length disproportion, together with ocular, cardiovascular and skeletal manifestations. The condition is an autosomal dominant trait, and can be transmitted from generation to generation with variable severity. The determinant gene FBN1 is situated at the chr...

Mullerian duct anomalies are the most common congenital anomalies of the reproductive system and septate uterus is the most frequently diagnosed Müllerian anomaly. The true incidence of Mullerian duct anomalies is difficult to state because some cases may be asymptomatic and there are pitfalls associated with various diagnostic methods. This is a case report of a 17-year-old primigravida with s...

In this paper, R&D results for the proposed Intermediate Fiber Tracker detector for the CDF upgrade are presented. We show a detailed study of the performance of the tracker under the high radiation levels expected during the Tevatron Run II operation. The system is proved to be highly eecient even after the expected 2 fb ?1 of delivered luminosity. A rate capability study has also been conduct...
