In a study of 2,682 selected attenders at a sexually transmitted diseases (STD) clinic for blacks in Durban, antibodies to human immunodeficiency virus type 1 (HIV-1) were detected in 63 (2.4%)--30 of 937 women (3.2%) and 33 of 1,745 men (1.9%). Women aged 15-19 years (P = 0.002) were at greater risk of HIV-1 infection than women of other age groups. Among men, HIV-1 seropositivity was associated with genital ulcer disease (GUD) (P = 0.007) and donovanosis (granuloma inguinale) (P = 0.02). Among seropositive men with donovanosis the probability of HIV-1 infection increased as the duration of lesions increased. When HIV-1 seropositive women were compared with a subgroup of 73 seronegative women with GUD, inflammatory cytological changes were associated with antibodies to HIV-1 (P = 0.02). Among women overall, HIV-1 seropositivity was associated with previous syphilis (P = 0.03). In men herpes zoster (P = 0.04) and in women lymphadenopathy (P = 0.002) accounted for HIV-1 seropositivity in patients with medical complaints. HIV-1 seropositivity in men with gonorrhoea and genital warts was less than in men without gonorrhoea (P = 0.001) and genital warts (P = 0.03). These results support the causal hypothesis of HIV transmission whereby mucosal discontinuity acts as a portal of entry for the virus. GUD and cervical inflammation secondary to STDs in seronegative subjects may facilitate HIV transmission. The relative risk of various STDs are probably dependent upon the duration of epithelial damage and exposure to HIV-1.

Survival data in the last decade for sexually transmitted diseases (STDs) other than human immunodeficiency virus (HIV) are uneven across the states/territories. The incidence of gonorrhoea decreased by more than 80%, but at different times in different patient groups, different states, and different anatomical sites. There was a resurgence of rectal gonorrhoea in homosexual men in 1989-1991. Resistance to penicillin steadily increased, and partial resistance to quinolones has emerged. There was a marked decline in syphilis in most states. Lymphogranuloma venereum is rare, and chancroid seen mostly in returning travellers from Southeast Asia; however, hundreds of cases of donovanosis are seen annually among rural Aborigines. The prevalence of genital infections with Chlamydia trachomatis remained stable at 2.5%-14% in STD clinics, and 5% in family planning clinics. The numbers of cases of clinical genital herpes and warts are mostly unavailable. However, specific serology for herpes simplex virus type 2 (HSV-2) indicates that 14% of antenatal clinic patients, and 40%-60% of STD patients have been exposed. Pap smears have detected the presence of human papilloma virus (HPV) in 14%-40% of various clinic populations. Exposure to hepatitis B in the non-Aboriginal population decreased markedly. Hepatitis C infection occurred in a high percentage of injecting drug users; the evidence for sexual transmission is not strong. An epidemic of hepatitis A infection occurred in male homosexuals in 1989-1991. Changes in the Australian sex industry resulted in marked improvements in the sexual health of local (but not international) sex workers. The high levels of STDs in Aboriginal communities continues to cause concern.

A case of extragenital donovanosis in a patient with AIDS is reported from Zimbabwe. Despite the rarity of donovanosis in Zimbabwe it is important that health workers are familiar with this disease since donovanosis increases the risk of HIV transmission and appropriate treatment is often successful even in patients with severe immunodeficiency.

Individuals presenting consecutively with genital ulcers in Kingston, Jamaica, underwent serological testing for human immunodeficiency virus (HIV) infection, chlamydial infection, and syphilis. Ulcer material was analyzed by multiplex polymerase chain reaction (M-PCR) analysis. DNA from herpes simplex virus (HSV), Haemophilus ducreyi, and Treponema pallidum was detected in 158 (52.0%), 72 (23.7%), and 31 (10.2%) of 304 ulcer specimens. Of the 304 subjects, 67 (22%) were HIV-seropositive and 64 (21%) were T. pallidum-seroreactive. Granuloma inguinale was clinically diagnosed in nine (13.4%) of 67 ulcers negative by M-PCR analysis and in 12 (5.1%) of 237 ulcers positive by M-PCR analysis (P = .03). Lymphogranuloma venereum was clinically diagnosed in eight patients. Compared with M-PCR analysis, the sensitivity and specificity of a clinical diagnosis of syphilis, herpes, and chancroid were 67.7%, 53.8%, and 75% and 91.2%, 83.6%, and 75.4%, respectively. Reactive syphilis serology was 74% sensitive and 85% specific compared with M-PCR analysis. Reported contact with a prostitute in the preceding 3 months was associated with chancroid (P = .009), reactive syphilis serology (P = .011), and HIV infection (P = .007). The relatively poor accuracy of clinical and locally available laboratory diagnoses pleads for syndromic management of genital ulcers in Jamaica. Prevention efforts should be intensified.

Donovanosis is a slowly progressive, granulomatous ulcerative disease , caused by Klebsiella (Calymmatobacterium) granulomatis. The disease is known to persist for years together, leading to complications. A male patient aged 30 years with underlying HIV-2 infection presented to the department of STD with painful ulceration over the genital region of 5 months duration, with absence of penis. Tissue smear from the ulcer and histopathological examination revealed large histiocytes with intracellular Donovan bodies (Pund cell). A final diagnosis of donovanosis with auto-amputation of penis with HIV-2 infection was made. The old conventional medicines, viz. streptomycin, doxycycline and amoxycillin, were effective. Though HIV-2 infections are milder than HIV-1 infections in all aspects, donovanosis in this HIV-2 infected case presented with complications. However, since the CD4 count was 748 cells/cmm, the severity is attributed to the long standing nature and negligence by the patient, and not to possible immunodeficiency.

Donovanosis is endemic in various parts of the world. Although donovanosis has been reported to co-exist with the human immunodeficiency virus (HIV) infection, to our knowledge there have been no reports of co-existent squamous cell carcinoma (SCC) in an HIV positive patient. In our case the patient did not respond to treatment for donovanosis and on biopsy we realized that the patient had coexistent SCC, which is hitherto unreported with granuloma inguinale.

Two infants, 6 months and 4 months of age, presented with bilateral or unilateral external auditory canal polyps and otorrhea, respectively. Additional findings on examination included otitis media and mastoiditis. Tympanic membrane perforation was noted in one patient and a postauricular abscess in the other. Incisional biopsies of the polyps and abscess were reported as nonspecific mixed inflammation and abscess wall, respectively. There was a limited response to an empirical 5-day course of trimethoprim sulfamethoxazole. The children were referred to the academic hospital, and excision of the polyps and biopsies of the middle ear, mastoid, and postauricular abscess was undertaken. All the biopsies demonstrated donovanosis. Reappraisal of the initial incisional biopsies also confirmed donovanosis. Trimethoprim sulfamethoxazole was administered to both patients for 3 weeks, with resolution of the lesions. Subsequent investigations confirmed genital tract donovanosis, human immunodeficiency virus seropositivity, acquired immunodeficiency syndrome, and pulmonary tuberculosis in both mothers. Heightened awareness of the occurrence of donovanosis at unusual sites and improved recognition of the histomorphological features of the disease, especially in small and superficial biopsies, are pivotal not only for its correct diagnosis in extragenital cutaneous and extracutaneous locations but also for timely and adequate therapy and an improved infant and maternal outcome.
