Resistance of bacteria to antibiotics is an increasing problem in many countries. Accurate locally relevant information is essential for detection and control of emerging resistance and to facilitate choice of empirical antibiotic therapy in the immediate management of seriously ill patients. We have determined the minimum inhibitory concentration of piperacillin/tazobactam for 97 strains of bacteria (55 Enterobacteriaceae, 13 non-fermentative Gram-negative bacilli, 22 Staphylococcus aureus, 6 Enterococcus faecalis and 1 Bacillus cereus) isolated from blood cultures and compared its activity to that of amoxycillin, co-amoxiclav, cephalothin, cefotaxime, ceftazidime, ciprofloxacin, gentamicin, piperacillin, cefotaxime. ⋯ Of all isolates 75 per cent were sensitive to piperacillin/tazobactam, compared with amoxycillin 22 per cent, cephalothin 35 per cent, piperacillin 41 per cent, co-amoxiclav 52 per cent, cefotaxime 59 per cent, ceftazidime 60 per cent, gentamicin 74 per cent and ciprofloxacin 77 per cent. Two isolates (1 E. coli and 1 Klebsiella pneumoniae) with antibiograms consistent with the relatively new resistance phenomenon of extended spectrum beta-lactamase production were identified. The spectrum of activity of piperacillin-tazobactam for empirical antibiotic therapy is significantly greater than that of piperacillin alone and is similar to that of ciprofloxacin and gentamicin.

To our knowledge, only a few epidemiological reports on the prevalence of hepatitis E antibodies in Saudi blood donors have been published. Men of several nationalities, donating blood at King Khalid National Guard Hospital (Jeddah, Saudi Arabia) were selected (n = 593) for this study examining the seroprevalence of hepatitis E virus (HEV) in the local male donor population and testing the relationship of the antibody to HEV (anti-HEV) to donor characteristics using Odds Ratio (OR) and Chi-square statistic. The prevalence of anti-HEV in the group examined was 16.9 per cent (100/593). ⋯ Donors who were 40 yr and over had significantly higher seroprevalence than those donors who were 30 yr or younger (OR = 2.5, p = 0.006). There was a significant association between anti-HEV and anti-HCV with donors who were positive to anti-HCV having about 5 times the risk of HEV than those who were anti-HCV negative (p = 0.02). These findings demonstrate the high seroprevalence rate of anti-HEV among male blood donors in Saudi Arabia.

Paediatric HIV infection has become a major burden on families, communities and health services worldwide. The vast majority of children now acquire HIV as a result of mother to infant (vertical) transmission. Recent major advances have occurred following the greater understanding of the risk factors for perinatal transmission and the role of antiretroviral therapy in preventing transmission. ⋯ Definitive diagnosis of HIV infection in infancy has been difficult in the past. Direct viral detection methods now allow the reliable diagnosis of HIV infection in the first few months of life. The most effective intervention to reduce perinatal HIV infection will be the better identification of HIV positive pregnant women with the subsequent introduction of measures to interrupt vertical transmission of HIV.

Perianal hidradenoma papilliferum occurring in a male: a case report.
Hidradenoma papilliferum is a rare apocrine gland tumour, described only once previously in a male. We present the second such case.
