Alterations in the apoptotic process in lymphoid tissues is a common condition which is encountered in the severely septic animal and critically ill patient. Here we attempt to delineate the pathological significance of these apoptotic changes and the role of Fas-FasL mediated contribution to this process.

Risk of infantile hypertrophic pyloric stenosis after maternal postnatal use of macrolides.
A case report has suggested that exposure to erythromycin through breast milk might cause infantile hypertrophic pyloric stenosis. This study therefore examined whether macrolides, transmitted via breast milk, increase the risk of infantile hypertrophic pyloric stenosis in neonates. ⋯ The odds ratios for infantile hypertrophic pyloric stenosis varied between 2.3 and 3.0 according to different periods of postnatal exposure, and after stratification for gender they were 10.3 [95% confidence interval (95% CI) 1.2-92.3] for girls and 2.0 (95% CI 0.5-8.4) for boys. The use of macrolides during breast-feeding increases the risk of infantile hypertrophic pyloric stenosis.

Comparative StudyNatural history of hyperlactataemia in human immunodeficiency virus-1-infected patients during highly active antiretroviral therapy.
A study on the course of hyperlactataemia during highly active antiretroviral therapy (HAART) and the association between hyperlactataemia and antiretroviral drugs was conducted at the outpatient department, Rigshopitalet, Copenhagen. Lactate levels were monitored in 848 patients during a study period of 1 y. Longitudinal analysis was performed on all human immunodeficiency virus-1-infected patients who had plasma lactate > 2.1 mM. ⋯ In conclusion, symptomatic hyperlactataemia is uncommon, while asymptomatic hyperlactataemia is a frequent and apparently benign condition unlikely to progress to lactic acidosis. A significant association between stavudine and hyperlactataemia was confirmed. The unexpected association between ritonavir and hyperlactataemia will need confirmation in future studies.

ReviewImpact of antibiotic resistance on the treatment of sepsis.
Antibiotics are essential to the treatment of bacterial sepsis as they reduce the bacterial burden. The impact of bacterial resistance has recently been studied and found to be important in a range of conditions. Resistance to antibiotics can be defined genotypically, phenotypically and clinically through pharmacokinetic/pharmacodynamic studies and their correlations with clinical outcomes. ⋯ In the latter case, dosage regimens have to date been adequate to overcome laboratory-defined resistance. Early indications are that de-escalating therapy from broad-spectrum initial coverage after results of cultures and susceptibility tests become available does not jeopardize outcomes, and further prospective studies are warranted. There is now convincing evidence that broad-spectrum initial therapy to cover the likely pathogens and their resistances pending culture results is mandatory in sepsis to minimize adverse outcomes.

Development of antibodies against cytomegalovirus, varicella-zoster virus and herpes simplex virus in Finland during the first eight years of life: a prospective study.
To clarify when antibodies against cytomegalovirus (CMV), varicella-zoster virus (VZV) and herpes simplex virus (HSV) develop among young children, 1206 serum samples collected prospectively from 199 children born in 1989 and 1990 were studied. The samples were drawn at the ages of 7 and 13 months, then yearly until the age of 5 y and then at 7 and 8 y. In each age group at least 106 samples were collected. ⋯ The proportion of children with HSV antibodies remained low throughout the study, as only 17% of children had HSV antibodies at the age of 8 y. The data show that HSV infection is becoming acquired later in life and the proportion of uninfected children is increasing. The proportion of CMV infections during the perinatal period and early infancy remains high, in one-third of the children, and most children also have VZV infection during the early years of life.
