Cytomegalovirus (CMV) is responsible for the most common opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for these infections in patients positive for human immunodeficiency virus. CMV rarely presents as an intraluminal inflammatory mass in the colon. Here we report the case of a CMV infection presenting as a mass-like lesion in an...

In acquired immunodeficiency syndrome (AIDS) the pulmonary opportunistic infections are due to the depression of cellular immunity and they are found in more than 50% of patients. Most frequently the infection is due to Pneumocystis carinii, Cytomegalovirus, Cryptococcus neoformans and Mycobacterium avium-intracellulare. Non-opportunistic infections in AIDS are mostly due to the Mycobacterium t...

This article provides the author's perspective on the development of digital hearing aids and how digital signal processing approaches have led to changes in hearing aid design. Major landmarks in the evolution of digital technology are identified, and their impact on the development of digital hearing aids is discussed. Differences between analog and digital approaches to signal processing in ...

Acquired immuno deficiency syndrome (AIDS) is a lethal epidemic which alarmingly decreases the body’s ability to combat disease resulting in susceptibility infection. Human Immunodeficiency Virus (HIV)/ AIDS have now moved from being viewed solely as public health issue human rights issue. The goal this regard strengthen anti-discrimination and other protective laws that safeguard vulnerable gr...

Evidence of simian immunodeficiency virus (SIV) infection has been reported for 26 different species of African nonhuman primates. Two of these viruses, SIVcpz from chimpanzees and SIVsm from sooty mangabeys, are the cause of acquired immunodeficiency syndrome (AIDS) in humans. Together, they have been transmitted to humans on at least seven occasions. The implications of human infection by a d...

According to the joint United Nations Programme on HIV and/or AIDS (UNAIDS) report (2010) on the global acquired immune deficiency syndrome (AIDS) epidemic, 33.3 million people were living with the human immunodeficiency virus (HIV) and AIDS by the end of 2009 worldwide (UNAIDS 2010:23). Unfortunately sub-Saharan Africa still seems to bear an ‘... inordinate share of the global HIV burden’ (UNA...

The incidence of suicide in patients with the diagnosis of acquired immunodeficiency syndrome (AIDS) in the state of Texas during the period between January 1986 and August 1987 was determined. AIDS patients were found to have a rate of suicide higher than expected when compared to the general population. The results of this study document this trend which has important implications in the care...

Thirty-two patients with AIDS related complex (ARC) or acquired immunodeficiency syndrome (AIDS) underwent 67Ga scans as part of their evaluation. Three patterns of 67Ga biodistribution were found: lymph node uptake alone; diffuse pulmonary uptake; normal scan. Gallium-67 scans were useful in identifying clinically occult Pneumocystis carinii pneumonia in seven of 15 patients with ARC who were ...

Opportunistic infections such as Pneumocystis carinii pneumonia are well-recognised in patients with the acquired immune deficiency syndrome (AIDS). Anaemia due to a variety of causes also occurs in AIDS. Persistent infection with parvovirus (B19) causing severe anaemia has been reported in patients with leukaemia and congenital immunodeficiency. A case is now reported of parvovirus infection a...
