The effect of pentoxifylline on sperm movement characteristics and zona pellucida binding potential of teratozoospermic men
This study investigates the effect of pentoxifylline on sperm movement and zona pellucida binding. Spermatozoa from nine teratozoospermic patients (10.2 ± 6% normal forms) were included in the study. Test samples were ...
Preparation and clinical evaluation of a high viscosity saliva substitute.
Twenty-five xerostomic patients were given an artificial saliva substitute we had prepared. In this study we evaluated its effect, period of relief, frequency of use, taste, smell, colour, aftertaste, consistency and desire ...
Infective endocarditis in children

Cervical aortic arch
A cervical aortic arch was diagnosed in an 8-year-old girl. The role of digital subtraction imaging as an ideal diagnostic tool for this condition is emphasised.
Single photon emission computed tomography v. planar imaging in recent myocardial infarction using technetium-99m pyrophosphate
Radionuclide imaging of the myocardium with technetium-99m-labelled pyrophosphate (PYP) is a sensitive method for the diagnosis of a recent (2-7 days old) myocardial infarct. Although the sensitivity of planar imaging with ...
A comparison of heart rate variability in affected and unaffected members of families with progressive familial heart block type I
The presence of sinus bradycardia (less than 60/min) in patients affected by progressive familial heart block type I (PFHB1) and their inability to reach a target heart rate during exercise testing, prompted an investigation ...
The extent of progressive familial heart block type 1 - A new perspective
New data on the inheritance of progressive familial heart block type I (PFHB1) does not favour the theory that the original immigrant (founder of PFHB1 families) introduced the genetic abnormality into South Africa and ...
Favorable neonatal outcome after fetal entrapment and partially successful Zavanelli maneuver in a case of breech presentation
A 16-year-old primigravida woman presented in advanced labor with a singleton breech presentation. Vaginal delivery was considered to be possible, but entrapment at the level of the fetal thorax occurred. The Zavanelli ...
