the total diagnosed TB co-infection patients, 29 had active disease and were put on ATT. Nine patients had already been treated with ATT after being diagnosed with HIV infection. Patients with HBV were treated with 2NRTIs (Zidovudine + Lamivudine) + 1NNRTI (Efavirenz) and patients with syphilis were treated with Benzathine penicillin G, 2.4 MU IM in a single dose. The patients are on regular fo...

An uncommon variant in the pre-AIDS era, lues maligna is a nodular-ulcerative form of secondary syphilis. We present a case of a 41-year-old man with HIV infection who developed fever, chills, nausea, vomiting, right upper quadrant abdominal pain, weight loss, watery diarrhea, and a painless, nonpruritic rash. He had diffuse nodular-ulcerative lesions in various stages of development. He was fo...

A 30-yr-old man was referred for suspicious rectal cancer because of ulcerated lesions in the rectum and a palpable mass in left inguinal area. Sigmoidoscopy showed two indurated masses and histologic evaluation of biopsy revealed obliterative endarteritis with heavy plasma cell infiltration. Both venereal disease research laboratories (VDRL) and fluorescent treponemal antibody absorption (FTA-...

Penicillin acylases (PA) are widely used for the production of semi-synthetic β-lactam antibiotics and chiral compounds. In this review, the latest achievements in the production of recombinant enzymes are discussed, as well as the results of PA type G protein engineering.

Combinations of penicillin plus tobramycin have been compared with penicillin plus gentamicin against 27 strains of enterococci isolated from blood cultures. Penicillin plus gentamicin was synergistic against all strains. The combination of penicillin plus tobramycin was equally effective against strains of Streptococcus facalis, but was ineffective against all four strains of S. faecium tested.

The use of the quantitative nasal culture was investigated as a means of evaluation of new antimicrobial drugs in man. Cyclacillin was somewhat more active in vitro than penicillin G against penicillin G-resistant organisms. Cyclacillin was highly effective in suppressing staphylococci susceptible to penicillin G in nasal carriers but did not suppress staphylococci resistant to penicillin G. Al...

Hair loss is not a common feature of secondary syphilis. There are two types of syphilitic alopecia: “symptomatic” type where hair loss is associated with other symptoms of secondary syphilis, and “essential” alopecia that is either patchy (“moth-eaten” type), diffuse pattern with a generalized thinning of the scalp hair, or a combination of both without any other mucocutaneous signs of syphili...

BACKGROUND Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain significant causes of morbidity and mortality in resource-limited settings. In Zimbabwe ARF/RHD characteristics have not been systematically documented. OBJECTIVES To document cases of ARF/RHD among children presenting at referral hospitals in Harare, Zimbabwe, determine their clinical and echocardiographic charac...

BACKGROUND Syphilis infection during pregnancy leads to avoidable morbidity and mortality and remains a significant problem in sub-Saharan Africa. Despite global initiatives to increase the proportion of pregnant women screened, implementation has been slow. We sought to investigate the feasibility of adding syphilis screening within an integrated antenatal HIV clinic. METHODS Pregnant women ...
