Selective IgA Deficiency in Rh-Negative Women

Abstract. Sera obtained from 15,500 Rh-negative pregnant women were screened for presence of serum IgA. 12 out of 15,500 or 0.08% of the women were deficient in serum IgA, and only one of these 12 women had anti-IgA antibody of broad specificity. Nine women with IgA deficiency received anti-Rh_o γ-globulin within 72 h after delivery. None of them developed anti-IgA antibodies 3–6 months following injection of anti-Rh_o γ-globulin. Administration of Rh immune globulin to one subject (case No. 5) in this group who has class-specific anti-IgA was not associated with any untoward reactions, and there was no significant change in the antibody level.     

Pantoea peritonitis in a patient receiving chronic ambulatory peritoneal dialysis

Pantoea agglomerans is usually the most common organism transmitted through plant thorn injuries. This report is of a female patient maintained on chronic ambulatory peritoneal dialysis (CAPD) who developed peritonitis attributed to P. agglomerans. Peritonitis is an uncommon complication of P. agglomerans and there is no previous report of peritonitis associated with this organism in a CAPD patient. The source of infection was thought to be due to rose-thorn injury. Antibiotic therapy with ceftazidime and amikacin i.p. led to a clinical improvement, with disappearance of the organism in the peritoneal fluid.     

Optimizing antimicrobial therapy for gram-positive bloodstream infections in patients on hemodialysis

Infections with gram-positive organisms are highly prevalent in hemodialysis patients and are a major cause of morbidity and mortality in this population. Antimicrobial therapy is widely used to treat these infections, and prolonged therapy with these agents is often necessary. Extensive use of antimicrobials in hemodialysis patients has resulted in a growing threat of resistance, especially among gram-positive bacteria such as Enterococcus spp and Staphylococcus aureus. Vancomycin-resistant enterococci and S. aureus isolates with reduced susceptibility to vancomycin are increasingly being reported in hemodialysis patients. Additionally, resistance of these organisms to newer agents, such as linezolid and daptomycin, has been documented. Appropriate utilization of antimicrobial therapy to treat these organisms requires an understanding of the pharmacokinetic and pharmacodynamic principles to optimize therapy and avoid adverse drug events. The pharmacokinetic and pharmacodynamic profile of antimicrobial agents can be significantly altered in patients with chronic kidney disease. This review will describe mechanisms of antimicrobial resistance among common gram-positive organisms. The pharmacokinetic and pharmacodynamic principles of cephalosporins, vancomycin, aminoglycosides, linezolid, and daptomycin and applications for use of these agents in the treatment of patients with bloodstream infections on hemodialysis are discussed.     

Topical phenytoin in diabetic ulcers: a double blind controlled trial

Data of 57 patients who completed the trial and 13 who did not, were analysed. With phenytoin, there was a marginal: increase in the reduction of mean ulcer area and acceleration of effect 3rd on 4th week. With control: the number completing the trial was larger: response to treatment was better in grade II ulcers, Table IV. This study has the hall marks of a real clinical trial, has raised the possibility of wound healing properties of phenytoin and confirms the results of others.     

Gerbode's defect--a rare type of ventricular septal defect

We report on an elderly lady in the sixth decade of life with congenital Gerbode's defect who refused surgery. She has atrial fibrillation, massive cardiomegaly and repeated episodes of lower respiratory tract infection.
