We examined the incidence, aetiological factors and outcome in 40 cases of nonimmune hydrops fetalis (NIH) and suggest a rational approach to management. The incidence of NIH was 1 in 830 deliveries during the last 10-year period. In spite of extensive antenatal and postnatal investigation no cause could be established in 14 (35%) cases. A probable aetiological factor was found in 65% of cases. These included viral infection (7), cardiovascular (6), twin-to-twin transfusion (3), chromosomal abnormality (3), other malformation syndromes (4), renal dysplasia (1), laryngeal atresia (1) and severe fetomaternal haemorrhage (1). Five of the 40 fetuses survived, 2 treated antenatally for tachyarrhythmia, 2 had spontaneous resolution and the fifth fetus had repeated intrauterine transfusions because of human parvovirus B19-induced anaemia. After diagnosis of nonimmune hydrops fetalis, early referral to a tertiary centre is to be encouraged for investigation and provision of intensive perinatal care. Investigation allows parents to be counselled appropriately that the mortality is no longer 100% and a steadily growing number may be amenable to some form of fetal therapy.

During pregnancy BMV is feasible, safe and effective. Maternal and fetal outcomes are excellent. Growth and milestone of development are not affected.

Tinnitus is a phantom auditory perception that occurs in humans. Tinnitus, which is a distressing problem affecting many people around the world, is commonly referred to as ringing in the ears. No effective drug therapy is available for this elusive disease, although much research work into mechanism and possible treatment is underway. As yet, there are no Food and Drug Administration approved drugs available and the quest for a new treatment option for tinnitus focus on important challenges in tinnitus management. A number of options have been used to treat patients with tinnitus, but outcomes have been limited. A new, curative modality will provide a turning point in the management of tinnitus. The purpose of this review article is to discuss the pathophysiology, global burden, current treatment, and prevention of tinnitus, with future prospective studies in new drug therapy for this elusive condition.
