Associated factors of the co-occurrence of trachoma and soil-transmitted helminthiases in children 1 to 9 years old in rural communities of the Amazon basin in Loreto Department, Peru: Results from a population-based survey.

BACKGROUND: There is evidence of the occurrence of trachoma in Peru, and studies have shown that soil-transmitted helminthiases (STH) are affecting rural communities in the Amazon basin in Loreto Department. This study was done to estimate trachoma prevalence, STH prevalence, and the associated factors for both diseases in children aged 1-9 years in rural communities of Peru. METHODOLOGY: A population-based cross-sectional survey was carried out in rural communities of Loreto. A standardized survey questionnaire with individual and household risk factors related to both diseases was used. Ocular examination was done for all participants aged one year and above, and eye swab samples were collected from children with follicular trachoma (TF). Anthropometric measurements, stool samples for STH, and blood samples for hemoglobin measurement were taken from children. PRINCIPAL FINDINGS: TF prevalence was 7.74% (95% CI 5.08-11.63%), STH prevalence was 49.49% (95% CI 25.00-52.43%), and prevalence of co-occurrence of both diseases was 5.06% (95% CI 2.80-8.98%) in children aged 1-9 years. Being at age 3-8 years old (AOR = 6.76; 95% CI 1.346-33.947), have an unclean face (AOR = 24.64; 95% CI 6.787-89.444), and having been dewormed in the last six months (AOR = 2.47; 95% CI 1.106-5.514), were risk factors of TF. Being a female (AOR = 0.22; 95% CI 0.103-0.457) was associated with decreased odds of TF. Having been dewormed in the last six months (AOR = 0.30; 95% CI 0.139-0.628) was a preventative factor for STH. Risk factors for children with both diseases mirrored the findings for risk factors for individual diseases. CONCLUSIONS: Neglected tropical diseases and associated risk factors overlap in communities living in vulnerable conditions in the Amazon basin of Peru. These findings support the need to implement integrated interventions, including mass drug administration, water, sanitation, and hygiene for both diseases in the study area.

[Efficacy and tolerance of pentamidine for treatment of cutaneous leishmaniasis caused by por L. (V) panamensis in Colombia]. / Eficacia y tolerancia de la pentamidina en el tratamiento de la leishmaniasis cutánea producida por Leishmania (V.) panamensis en Colombia.

INTRODUCTION: Current treatment for human cutaneous leishmaniasis (CL) relies on pentavalent antimonials. Although efficacy of these drugs is high (around 85%), their widely documented toxicity and increasing resistance makes the search for therapeutic alternatives a priority for endemic countries. OBJECTIVE: To evaluate the efficacy and tolerability of the pentamidine isethionate for the treatment of cutaneous leishmaniasis caused by L. (V) panamensis in a pilot clinical trial. MATERIALS AND METHODS: Sixty three individuals suffering CL were enrolled. Patients received four intramuscular injections of pentamidine (4 mg/Kg/injection) administered every other day, and both clinical efficacy and side effects were documented during the following 6 months. RESULTS: Of the 63 patients enrolled, 43 could be followed for 6 months. 86% (37/43) of treated patients healed all their lesions by 1.5 months after therapy. Treatment failure was observed in only five patients (11.6%; 5/43). One patient showed relapse. Overall tolerance of treatment was good, with adverse events such as local pain and swelling at the site of injection, dizziness and fever, varying from mild to moderate. Hypoglycemia, hypotension or diabetes were not observed. DISCUSSION: These results confirm the previously reported efficacy of pentamidine for the treatment of CL in Colombia and Brazil, and, additionally, highlight the low intensity and frequency of side effects in a civilian population. No serious adverse events were recorded.

Ebola in West Africa.

Ebola viral disease (EVD) is a severe and life-threatening disease. The current Ebola outbreak in West Africa entered its second year and is unprecedented because it is the largest one in history, involved urban centers and affected a large number of health care workers. It quickly escalated from medical into a humanitarian, social, economic, and security crisis. The primary pillars to prevent EVD are: early diagnosis, isolation of patients, contact tracing and monitoring, safe burials, infection prevention and control and social mobilization. The implementation of all these components was challenged in the field. Key lessons from this Ebola outbreak are that countries with weak health care systems can't withstand the major outbreaks; preparedness to treat the first confirmed cases is a national emergency; all control measures must be coordinated together and community engagement is the great factor to combat this disease.
