RESUMEN
Children in developing tropical countries are frequently undernourished. In rural areas, they are also often affected by Buruli ulcers. The treatment of this mutilating disease is sometime long and difficult for malnourished patients. Moreover, the eating behavior of patients with Buruli ulcers does not promote its quick healing, with numerous foods prohibited. They eat fewer fruits and legumes, which are rich in vitamins and minerals. Our survey in two health centers showed that only 8% ate fruits and legumes, and 29% leafy greens. This food deprivation increases their nutritional deficiencies. We conducted a nutritional intervention among Buruli ulcer patients (30 patients) in one center, and compared their healing with that of Buruli patients without nutritional care (n = 21). Those patients who received the intervention spent less time at the hospital (less than six months). Our study shows the association between the healing of Buruli ulcers in Côte d'Ivoire and good nutritional status: those with the intervention healed faster and presented fewer disabilities than the control patients.

In industrialized countries, the emergence of potentially pandemic influenza virus has invited reactions consistent with the potential threat represented by these infectious agents. However, with globalization, controlling epidemics depends as much on an effective global coordination of control methods as on preparedness of northern and southern national health care systems, at the core of which are health care workers. Our study was conducted in the National Hospital of Niamey, the main Nigerian hospital. Its objective was to evaluate the knowledge of health care professionals regarding flu pandemic and control of infection. We interviewed 178 nursing staff, doctors and paramedics on the basis of a survey. This study - the first to our knowledge to explore these issues in the African context-revealed that caregivers have a rather good mastery of theoretical knowledge. Nevertheless, beyond theoretical knowledge, miscellaneous factors compromise the effectiveness of the health care structure. Some of them seem to occupy a critical position, particularly the absence of shared references among sanitary authorities and health care professionals, and the weaknesses of global coordination of preventive activities and case management.

PURPOSE: Haiphong is the second city of Vietnam most affected by HIV infection. Penicilliosis represents the third leading cause of opportunistic infection. However, this systemic fungal infection remains poorly knew by practitioners. This study aimed to clarify the clinical, diagnostic and therapeutic aspects of penicilliosis. METHODS: It is a descriptive study, prospective and retrospective, conducted over a 3-year period in Viet Tiep hospital, Haiphong. RESULTS: With 94 cases, penicilliosis represented 11% of opportunistic infections. The patients were young (mean: 33 years) and male (87%). The main symptoms were persistent fever (99%), weight loss (88%), skin lesions (86%), hepatomegaly (69%) and lymphadenopathy (68%). Anemia was noted in 77% of cases. The average CD4 count was 29/µL. The culture of skin biopsies and blood culture were positive for Penicillium marneffei in 94% and 90% of cases, respectively. Despite antiretroviral and antifungal therapy, the mortality rate was 18%. Itraconazole monotherapy, administered in 53 patients due to the unavailability of amphotericin B, did not significantly affect the survival compared to the recommended treatment received by the 41 other patients. CONCLUSION: In Haiphong, penicilliosis is one of the most frequent and severe opportunistic infections of AIDS. The diagnosis should be considered in all febrile and immunocompromised patients having spent time in Vietnam. The prognosis can be improved by early diagnosis through the blood culture and a good adherence to an appropriate antifungal therapy.

A prospective epidemiological study was conducted to evaluate the incidence of febrile cough episodes among adult Muslims travelling from Marseille to Saudi Arabia during the Hajj pilgrimage and to assess if use of statin had an influence on this incidence. In total, 580 individuals were presented with a questionnaire. A significant proportion of individuals had chronic medical disorders, e.g. diabetes mellitus (132, 22.8%) and hypertension (147, 25.3%). Pilgrims had a low level of education and a low employment rate. Sixty (10.3%) were treated with statins for hypercholesterolemia. Four hundred and fourty-seven pilgrims were presented a questionnaire on returning home. A total of 74 travellers (16.6%) experienced fever during their stay in Saudi Arabia (67 attended a doctor) and 271 (60.6%) had cough (259 attended a doctor); 70 travellers with cough were febrile (25.9%). Seventy per cent of the travellers who suffered cough episodes developed their first symptoms within 3 days, suggesting a human to human transmission of the responsible pathogen, with short incubation time as evidenced by a bimodal distribution of cough in two peaks at a 24 h interval. None of demographical and socioeconomic characteristics, underlying diseases or vaccination against influenza significantly affected the occurrence of cough. Diabetes correlated with an increased risk of febrile cough (OR = 2.02 (1.05-3.89)) as well as unemployment (OR = 2.22 (0.91-5.53)). Use of statins had no significant influence on the occurrence of cough and/or fever during the pilgrimage. This result suggests that while treatment with a statin has been demonstrated to reduce the mortality from severe sepsis associated with respiratory tract infections, it probably does not play a role in the outcome of regular febrile cough episodes as observed in the cohort studied here.

Hyperreactive malarial splenomegaly (HMS) is the chronic stage of a long-term stimulation of the immune system secondary to plasmodial infections, more frequently in genetically predisposed patients. HMS is a leading cause of large tropical splenomegaly in endemic zones but has been described in immigrants from Africa and in some European expatriates living in endemic countries. Diagnostic criteria include: long-term stay in a endemic zone, often large splenomegaly, high IgM titer, high antiplasmodial antibody titer, regression by at least 40% of splenomegaly six months after curative antimalarial treatment. In tropical settings, B-cell lymphoma and splenic lymphoma are the main differential diagnoses, which may be identified by a clonality analysis. Recent studies suggest that HMS can be treated by a short-term antimalarial therapy as long as the patient resides out of a malarial endemic country.

Many great discoveries have been made by chance but some have been the result of human perseverance and ingenuity. A sterling example of the second case is quinquina that was discovered in Peru and is now produced in Java. Quinquina has gone through centuries without losing its medical efficacy that efficacy allowed the exploration and colonization of Africa and played a key role in the ability to conduct overseas military campaigns. Because of its strategic importance, it was a coveted resource. It led to the discovery of homeopathy and dyes, allowed the development of organic chemistry, and has been used to make alcoholic bitters and soft drinks.

In a rural area of intense and permanent malaria transmission in Southwest Côte-d'lvoire, traditional midwifes of the Yacouba ethnic group, with also an important function for the children health and care, were interviewed in 2002 about their knowledge of the infantile pathologies. Their nosology is greatly based on symptoms and etiologic explanations of the disorder of secretions. The accumulation of a viscous liquid in different parts of the body, especially in the chest, the throat or the head, explains numerous febrile or afebrile diseases, including malnutrition. Some pathologies, particularly convulsions, are described by analogy with animals behaviour Relations between these entities and the biomedical ones are difficult to establish. The traditional care and treatments result from these concepts. A vomiting child or a child suffering from diarrhoea is subject to devices to evacuate his excess of liquid. Yellow brews are used against jaundice. Furthermore, an important mistrust remains towards medical treatments particularly for all parenteral therapies. Health facilities are only used as a the last resort. Their bad reputation is confirmed by the high rate of mortality of patients coming often too late. To improve malaria care management, health-care workers have to take into consideration these concepts and also prove their abilities to ensure good medical practices.

OBJECTIVE: The authors had for aim to study epidemiological, clinical, and parasitological characteristics, as well as regimen received, of imported malaria cases hospitalised at the North University Hospital, in Marseilles, France. DESIGN: The patients presenting with imported malaria included in this study were hospitalised in the infectious and tropical diseases unit and in the pediatrics unit at the North University Hospital, from January 1, 2001 to December 31, 2003. Variables were prospectively collected and recorded. RESULTS: 352 patients including 240 adults and 112 children were included. Most of them (67% of the adults and 92% of the children) were contaminated during a trip to the Comoros Islands. Plasmodium falciparum was the most common species identified. 97.5% of adult and 98% of child patients back from Comoros did not take any chemoprophylaxis against malaria or took inadequate regimens. Halofantrin was the most commonly used drug for children to treat uncomplicated P. falciparum malaria. In adults, atovaquone-proguanil was used as a first line drug in the absence of vomiting, and a 3-day intravenous regimen of quinine-clindamycin in case of vomiting. CONCLUSION: The specificity of imported malaria in Marseilles is the high proportion of Comorian patients who go back home periodically to visit friends and relatives. A better education of the Comorian population in Marseilles, regarding malaria risks and prophylaxis, needs to be implemented.

BACKGROUND: Data about anti-malarial drugs prescription practices in Europe and the safety of imported malaria treatments are scanty. In 1999, a French consensus development conference published guidelines for the prevention and treatment of imported P. falciparum malaria. The impact of these guidelines has not been evaluated. AIM: To investigate the impact of these guidelines on the prescription of anti-malarials, and to evaluate the incidence of acute drug events (ADEs) leading to discontinuation of treatment. DESIGN: Cross-sectional survey. METHODS: Members of the medical staff in 14 French infectious and tropical disease wards completed a standardized form for each patient treated for imported malaria in 2001. A propensity score matching technique was used to estimate the risk of ADEs leading to discontinuation of the regimen. RESULTS: In the 474 patients studied, quinine was the first-line anti-malarial most often prescribed. Only 3% of patients received halofantrine. Mefloquine was associated with a RR of 4.9 (95%CI 3.2-7.4, p < 0.00001) risk of discontinuation of treatment due to ADEs. DISCUSSION: The very limited use of halofantrine indicates that the main practice recommendations of the guidelines have been taken into account. Mefloquine was associated with a substantial risk of discontinuing the treatment because of ADEs. This is a serious limitation for the use of mefloquine in the treatment of out-patients with imported malaria.

INTRODUCTION: Pulmonary dirofilariasis is an uncommon entity. Known as a zoonotic disease it can affect humans as a secondary host. A pseudo-tumor of the lung called "coin" lesion is usually detected while performing a chest X-ray for another reason. OBSERVATION: We present a case of pulmonary dirofilariasis due to Dirofilaria sp. in a 72 year old immunocompetent patient who underwent surgery for suspicion of a neoplasm. DISCUSSION: Human pulmonary dirofilariasis should be evoked in asymptomatic patient from endemic area of canine dirofilariasis presenting with a pseudo tumor of the lung.

Millions of people originating from tropical areas now live outside the country of their birth. As a consequence, the number of cases of diseases imported from the tropics and being seen by European physicians in immigrants is growing. As an example of such diseases, schistosomal appendicitis is a specific trait of infection with Schistosoma haematobium and is an uncommon cause of appendicitis in non-endemic areas. Treatment requires anti-schistomal medication in addition to surgery. Physicians, including surgeons, need to be aware of the possibility of seeing atypical presentations of parasitic diseases in immigrant patients.

Gnathostomiasis has rarely been described outside endemic countries. We report on a series of 5 patients (4 females, 1 male, mean age 42.2 years) who returned to France from South-East Asia and presented with cutaneous gnathostomiasis. The cutaneous lesions appeared within a mean period of 62 d (range 10-150 d) after return. They consisted of creeping eruptions in 3 patients (in addition one also had papules, one had nodules and hepatitis, and one had hepatitis; all 3 had profound asthenia) and recurring migratory swellings in 2 patients. The mean eosinophil count was 1546/mm3 (range 398-3245/mm3). Diagnosis was based on positive serological tests in 3 patients and seroconversion in 2 patients, and was confirmed by identification of Gnathostoma hispidum in a biopsy specimen from one of the seropositive patients. Albandazole (1-4 courses) was given as treatment. Recurrences may occur up to 24 months after apparent cure without reinfection. Gnathostomiasis should be considered when patients return from tropical countries and present with migratory swellings or creeping eruption that does not respond to the usual treatment for cutaneous larva migrans. Serological tests may be negative initially and thus need to be repeated to check for seroconversion. Treatment may require multiple courses of albendazole and a prolonged period of follow-up is necessary before cure can be confirmed.

The efficacy of oral chloroquine was assessed in 268 children aged from 6 to 59 months attending pediatric services in regional hospitals between September 1997 and December 1998, located in the five county towns of the sanitary regions of the Central African Republic. Chloroquine was prescribed at 25 mg per kg body weight, and administered over 3 days to patients suffering from uncomplicated malaria. Body temperature and blood smears including parasitaemia were recorded on days 0, 3, 7 and 14. The main objective of the present study was to evaluate the therapeutic efficacy of chloroquine in the treatment of uncomplicated malaria using in vivo tests according to the WHO protocol (1996). The secondary objective was to identify the predictive factors of chloroquine relapses. Early relapses rates were under 15% except in Bangui (40%). A recurrence of parasitaemia with fever, sign of late relapse, was noted in 9% of children in Bambari, 9% in Bangassou, 8% in Bangui, 5% in Bossangoa and 4% in Berberati. The rate of successfully treated patients was between 66% and 75% except in Bangui (36%). Only the places of study and anaemia in days 0 were significant predictive factors of therapeutic relapses. Since the emergence of chloroquine resistance cases to P. falciparum in 1983 in Central African Republic, the phenomenon has increased. According to our results, a strong chloroquine resistance appears in the capital Bangui. Therefore, chloroquine should be replaced there for the first line treatment of uncomplicated P. falciparum malaria. In the provinces, it doesn't seem necessary to change the current chloroquine-based first line treatment.

Malarone (atovaquone-proguanil) is a new option now available to French clinicians for prophylaxis and treatment of malaria. Administered by the oral route, malarone is almost 100% effective with few side effects. It is indicated for chemoprophylaxis in travelers entering areas with chloraquine-resistant Plasmodium falciparum. Compliance with prophylactic treatment is enhanced by the low frequency of adverse effects and the need to continue chemoprophylaxis for only 7 days after leaving the endemic area. For curative treatment of malaria, malarone is especially useful in patients with uncomplicated forms of Plasmodium falciparum malaria. This drug combination is also suitable as a stand-by treatment.
