Extragenital donovanosis of the foot

Donovanosis

Donovanosis is a chronic, progressive, and indolent bacterial disease that affects the skin and mucous membranes of the genital and perigenital regions, often associated with sexual transmission, and with low infectivity. The malignant transformation of donovanosis lesions occurs exceptionally, as is usually seen in long-term ulcerations.

Chancroid, lymphogranuloma venereum, granuloma inguinale, genital herpes simplex infection, and molluscum contagiosum

Chancroid, lymphogranuloma venereum, and granuloma inguinale may be considered as tropical venereal diseases. These diseases were a major diagnostic and therapeutic challenge in past centuries. Currently, patients with these bacterial infections that are endemic to the tropics occasionally consult with dermatologists in temperate climates. Due to the increasing frequency of travel to the tropics for tourism and work, as well as the increasing number of immigrants from these areas, it is important for dermatologists practicing in temperate climates to be familiar with the dermatologic manifestations of such infections, to be prepared to diagnose these diseases, and to treat these patients. All three "tropical" infections respond well to prompt and appropriate antimicrobial treatment, although herpes progenitalis still cannot be cured, and the number of people infected keeps growing; moreover, genital herpes can be transmitted by viral shedding before and after the visual signs or symptoms. Acyclovir, valacyclovir, and famciclovir can shorten outbreaks and make them less severe or even stop them from happening. There is currently no etiologic treatment for molluscum contagiosum, and the majority of treatment options are mechanical, causing a certain degree of discomfort. The molluscum contagiosum virus, unlike the other infectious agents mentioned, does not invade the skin.

Partner notification for sexually transmitted infections in developing countries: a systematic review

BACKGROUND

The feasibility and acceptability of partner notification (PN) for sexually transmitted infections (STIs) in developing countries was assessed through a comprehensive literature review, to help identify future intervention needs.

METHODS

The Medline, Embase, and Google Scholar databases were searched to identify studies published between January 1995 and December 2007 on STI PN in developing countries. A systematic review of the research extracted information on: (1) willingness of index patients to notify partners; (2) the proportion of partners notified or referred; (3) client-reported barriers in notifying partners; (4) infrastructure barriers in notifying partners; and (5) PN approaches that were evaluated in developing countries.

RESULTS

Out of 609 screened articles, 39 met our criteria. PN outcome varied widely and was implemented more often for spousal partners than for casual or commercial partners. Reported barriers included sociocultural factors such as stigma, fear of abuse for having an STI, and infrastructural factors related to the limited number of STD clinics, and trained providers and reliable diagnostic methods. Client-oriented counselling was found to be effective in improving partner referral outcomes.

CONCLUSIONS

STD clinics can improve PN with client-oriented counselling, which should help clients to overcome perceived barriers. The authors speculate that well-designed PN interventions to evaluate the impact on STI prevalence and incidence along with cost-effectiveness components will motivate policy makers in developing countries to allocate more resources towards STI management.

Prevalence of gonococcal and chlamydial infections and sexual risk behavior among youth in Addis Ababa, Ethiopia

BACKGROUND

No community-based study on the magnitude of sexually transmitted diseases (STDs) has ever been conducted among young people in Ethiopia.

GOAL

To assess the magnitude of Chlamydia trachomatis and Neisseria gonorrhoeae infections and status of sexual risk behavior among youths (15-24 years old) in Addis Ababa, Ethiopia.

STUDY DESIGN

Youths in or out of school residing in two (of the six) administrative zones in Addis Ababa served as the study population. Participants filled out a self-administered questionnaire related to sexuality and its sociocultural determinants. First-void urine (FVU) was analyzed for gonorrhea and chlamydial infection by polymerase chain reaction (PCR).

RESULTS

A total of 561 youths took part in the study. Urine PCR was performed for 522 of them. Nine subjects (1.7%) were found to have and N gonorrhoeae and C trachomatis infections. There were five cases (1.0%) involving each agent. Double infection was noted in one female subject. All but one of the infections were detected among the out-of-school youths (chi-square = 4.5; < 0.05). None of these subjects complained of symptoms suggestive of an active STD. One-third (188/561) reported having had sexual intercourse. The prevalence among sexually active youths was thus 4.8% (9/188) for both infections combined (2.7% for each agent). While 7/52 (13.5%) of the sexually active females were found to also have STDs, only 2/136 (1.5%) of the males had an STD (chi-square = 8.0; < 0.01). Report of sexual activity was significantly associated with being male, an age of >/=20 years, out-of-school status, and report of alcohol/khat (amphetamine-like substance) consumption. Females reported less condom use, whether they were in or out of school and independent of age.

CONCLUSIONS

Out-of-school youths, especially females, took more sexual risk and were exceedingly susceptible to STDs. This calls for alternative group-targeted strategies for sex education, disease prevention, and STD screening and management.

An uncommon cause of a destructive vulval lesion

We present a case of a 39-year-old woman with a vulval lesion, which macroscopically looked consistent with a fungating squamous cell carcinoma of the vulva. However, further investigations demonstrated a less common cause for this presentation.

Health sector reform and STD/AIDS control in resource poor settings--the case of Tanzania

Integration in health sector reform tends to mean horizontal interaction between vertical programmes. This can result in a larger more complex system than a set of individual vertical programmes. This article looks at the HIV/AIDS programme in Tanzania and the possible impact of system-wide health sector reform involving 'decentralization' and horizontal integration. It implies that the build-up to reform is likely to be costly, at least initially (although eventually the system may become more cost-effective). Integration can thus save resources, but it will also demand additional inputs, and may lead to reduced service output if operations depend on horizontal functions that fail to deliver. The objective of reform must be to create a reasonably sized, well-balanced, system which aims to maximize the output of quality services, both preventive and curative, and to facilitate community efforts to improve health. It is doubtful whether present reform efforts in Tanzania will contribute to more effective services, if not based on a more thorough analysis adapted to the local situation and given considerably more resources, both human and financial. There is also a risk that key preventive programmes, such as those aimed at the control of STD/AIDS, will be further weakened because of both integration with subsequent dependence on poorly functioning horizontal units and reduction in allocated resources.

The use of epidemiologic mass treatment and syndrome management for sexually transmitted disease control

BACKGROUND

Epidemiologic mass treatment and syndrome management are two sexually transmitted disease (STD) control strategies that are receiving increased attention internationally. The former is a population-based intervention, whereas the latter attempts to improve the quality and efficiency of clinic-based STD case management.

METHODS

The published literature on these subjects was reviewed.

RESULTS

Epidemiologic mass treatment refers to treatment of whole communities (mass treatment) or high-risk subgroups within communities (targeted presumptive treatment) based on high STD prevalence rates. Syndrome management overcomes many obstacles to provision of quality STD case management by basing treatment decisions on recognition of easily identifiable syndromes. Experience with application of these strategies is summarized, and their possible use as STD control measures in communities with similar conditions is discussed.

CONCLUSIONS

Epidemiologic mass treatment may be an effective approach to rapidly reduce STD transmission in high prevalence communities, especially when high-risk core groups are effectively reached. Once high prevalence rates are brought down, however, longer term strategies, including improved STD case management, are essential to maintain reduced rates.
