Rectal histopathology was evaluated in 34 cases (2 months-12 yrs old) of endemic "invasive diarrhea" [> 20 WBCs per high-power field on stool microscopy with (RBC positive) or without (RBC negative) associated RBCs] where S. dysenteriae (n = 9), S. flexneri (n = 11), and nontyphoidal Salmonella were isolated as the sole identifiable enteropathogens. Persistent diarrhea (> 14 days duration) was more common with Salmonella infection whereas RBC-positive "invasive diarrhea" was more frequent with Shigella, particularly S. dysenteriae (all cases) infection. The histopathological profile was comparable to the earlier descriptions of infective colitis to a large extent and the nature of the infecting organism could not be determined on the basis of rectal histology alone. The other noteworthy features were as follows: (i) mild crypt distortion (26%) and branching (21%) in both Shigella and Salmonella infection; in Salmonella infection, dilation of the glands was significantly greater with persistent diarrhea; (ii) presence of chronic inflammatory cells either alone or in combination with neutrophils in 62%; a predominant neutrophilic response was significantly higher with S. dysenteriae infection and an acute presentation; (iii) pseudomembrane formation (six subjects; 18%) especially in S. dysenteriae (four cases); and (iv) a significant association of neutrophilic response, edema, and neutrophils within the vessels in the lamina propria and mucin depletion in the glands with RBC-positive "invasive diarrhea."

A set of plasmids conferring resistance to several antibiotics, including the combination of trimethoprim and sulfamethoxazole, has been isolated from Escherichia coli following conjugative cotransfer from a clinical isolate of Shigella flexneri 2a. One of the plasmids, pCN1, was shown by subcloning and DNA sequencing to carry a gene encoding a trimethoprim-insensitive dihydrofolate reductase identical to that found in E. coli transposon 7. This plasmid was also shown to confer resistance to both streptomycin and spectinomycin by production of an adenylyltransferase that inactivated the drugs and the gene encoding this enzyme has also been sequenced. A second plasmid from the set, pCN2, was shown to inactivate streptomycin by a phosphotransferase mechanism and also to confer resistance to sulfonamides. The third plasmid from the set could not be correlated with a drug-resistance phenotype, but does appear to play a crucial role in plasmid mobilization.
It is important to target antibiotic therapy for acute exacerbation of chronic bronchitis specifically for patients who will truly benefit, adapting the prescribed compound to the bacterial target.

A quasi-experimental study was performed in 177 patients with a confirmed or probable diagnosis of paracoccidioidomycosis. Treatment was divided into two stages: 1) initial, which was continued until clinical cure was achieved and the erythrocyte sedimentation rate decreased to normal values; 2) complementary, which was continued until serologic cure was achieved. Medians were compared via the Mann-Whitney test, and frequencies were compared via the chi-squared test. The assessment of variables as a function of time was performed using Kaplan-Meier curves and Cox regression. The significance level was established as p≤0.05.

Three hematopoietic stimulants have been used in patients with HIV infection and a variety of AIDS-related complications. Both G-CSF and GM-CSF have demonstrated the ability to correct leukopenia related to HIV infection and ameliorate the drug-related myelosuppressive effects of zidovudine, trimethoprim/sulfamethoxazole, ganciclovir, and, in the case of GM-CSF, alpha-interferon, and cancer chemotherapies. Erythropoietin has been successfully used to ameliorate the anemia associated with HIV infection and zidovudine therapy. Treatment with these hematopoietic stimulants is very well tolerated with minimal toxicity. Of the granulocyte stimulants, G-CSF appears to induce fewer side effects than GM-CSF in trials conducted to date. Future trials demonstrating that the amelioration of hematopoietic suppression by the colony-stimulating factors results in increased clinical response rates and improved survival are necessary to fully assess the value of this approach in the care of HIV-infected patients.
Of the 48 evaluable patients, 37 (77%) tolerated sulfamethoxazole-trimethoprim desensitization without toxic effects and continued to take sulfamethoxazole-trimethoprim daily. Desensitization failed in 11 cases (5 on day 1, 3 on day 2, and 1 each on days 9, 11, and 90). Acute hypotension and a nonfatal myocardial infarction developed in 1 of these patients. The factors that were predictive of failure were a relatively high CD4+ cell percentage (11% vs 8%; P = .008) and a relatively high CD4+/CD8+ ratio (0.27 vs 0.12; P = .02).

Qualitative research on existing knowledge and practices of parents and providers using key informant interviews, focus groups, clinic observation, and home visits. A workshop of local stakeholders produced messages and job aids for health care workers and parents that included counseling cards and posters for providers, and medication envelopes with educational messages for mothers. Draft mock-ups were tested, modified, and re-tested before final production and distribution.
