Passive sentinel surveillance system for sexually transmitted diseases in primary healthcare sites in Ethiopia, 1991-3.

BACKGROUND: In 1989 the ministry of health of Ethiopia launched an STD control programme to strengthen the STD case management capabilities at public health centres and hospitals. The programme included the introduction of a syndrome based system for notification of STD cases. We here report the data originated by the syndromic case reporting system under programme conditions. METHODS: 35 (17%) of the total 225 hospitals and public health centres of Ethiopia were included in the programme. Information relevant to the years 1991 to 1993 was analysed at mid 1994. RESULTS: 32 clinical sites (91% of the total) provided at least one monthly report. The proportion of monthly reports received was 65% of those due, ranging from 51% in 1991 to 73% in 1992 and 42% in 1993. A total of 77,294 consultations for STD related symptoms were recorded, including 70,200 new cases, 6588 repeated consultations, and 506 partners of STD patients. Among first attendant patients 38,459 (52.7%) were males with a male to female ratio of 1:1. Urethral discharge and vaginal discharge were the leading cause of consultation among males (58%) and females (64%) respectively. The frequency of genital ulcer diseases was 26% among males and 15% among females. Inguinal adenopathy in the absence of genital ulcers was also frequent, accounting for 10% of consulting males and 5% of females. Based on Gram stain, gonorrhoea was identified in 64% of the cases of urethral discharge, while trichomoniasis and candidiasis were identified by wet mount in 28% and 16% of the cases of vaginal discharge respectively. CONCLUSIONS: STDs are a common cause of consultation at public health centre sites in Ethiopia. A syndromic case reporting system proved to be efficient and produced valuable information to initiate assessment of the problem and to set up bases for monitoring trends of STD morbidity.

Neurocysticercosis in an Italian traveler to Latin America.

Neurocysticercosis is rarely reported in short-term travelers, although the disease remains a major public health problem in tropical regions. We present a case of neurocysticercosis that was probably acquired by ingestion of Taenia solium eggs contained in the stomach of a pig butchered by the traveler. Complete clinical resolution was obtained by medical treatment, underlying the importance of early suspicion and diagnosis of the disease.

Short report: Diagnosis of tick-borne relapsing fever by the quantitative buffy coat fluorescence method.

The quantitative buffy coat (QBC) parasite detection method is a sensitive and specific tool for the diagnosis of malaria parasites. It is also useful for the diagnoses of other hemoparasites, including Trypanosoma, Babesia, and Leptospira. We report a case of relapsing fever diagnosed by this technique in a short-term traveler from Senegal. The diagnosis was confirmed by the standard Giemsa hemoscopy and by the identification of significant titers of antibodies to Borrelia spp. of tick-borne relapsing fevers by specific immunofluorescence and Western blot tests. The QBC technique seems to be useful in the diagnosis of tick-borne relapsing fever in blood samples and should be included in the management of fever in the traveler returning from tropical regions.

Malaria in migrants.

An increasing proportion of malaria cases in Italy is observed in immigrants revisiting their country of origin, but little specific research work has been carried out in this field. All malaria cases occurring from 1990 to 1998 at the Reference Clinic for Infectious and Tropical Diseases in Brescia were prospectically evaluated to compare clinical outcome in migrant and non-immune cases. No difference was observed between parasitaemia at diagnosis and time to clearance of peripheral parasitaemia. Clinical presentation was milder in migrants than in non-immunes, with an OR for severe malaria of 0.27 (c.i. = 0.09-0.84) (p = 0.01). Fever clearance time was significantly shorter in migrants (3.0 days, SD = 1.2) than in non-immunes (4.3 days, SD = 1.7) (p < 0.001). Among immigrants, the proportion of severe cases was higher in residents since 2 years or less (12.5%) compared to residents since 2 to 5 years (3.3%) and residents since more than 5 years (0.9%) (p = 0.02). The proportion of malaria cases who had used chemoprophylaxis was significantly lower among immigrants (30/272, 11.0%) compared to non-immunes (41/74, 55.4%) (p < 0.001). In a population based malaria KAP analysis among 504 migrants from malaria endemic countries, correct knowledge of malaria risk was reported by 351 (69.5%). Of 170 subjects who reported at least one visit back to the home country, 30 (17.6%) had sought pre-travel advice, 24 (14.1%) had started chemoprophylaxis and 7 (4.1%) had completed it during the last visit. Of 140 migrants who failed to seek pre-travel advice, 73 (52%) were unaware of malaria risk, 56 (40%) did not know how to protect themselves, and 11 (8%) refused to use protective measures. Migrants account for a significant proportion of imported malaria cases in industrialised countries. Clinical presentation is milder compared to non-immune subjects. The proportion of migrants who adopt malaria protective measure while returning home is very low, due to both unawareness of risk and inappropriateness of medical advice.

Long term treatment with clarithromycin for cryptosporidiosis and emergence of drug resistant disseminated infection due to Mycobacterium avium: case report.

Macrolide resistance in disseminated Mycobacterium avium infection is of major concern in AIDS patients as these drugs represent the main component of combination therapy. Clarithromycin and azithromycin should not be used alone for the treatment and prophylaxis of the disease because of the risk of selecting resistant strains. We report the case of a clarithromycin resistant disseminated M. avium infection in an AIDS patient, acquired after long term monotherapy with clarithromycin for the treatment of cryptosporidiosis.
