Randomized Controlled Trial Clinical TrialHuman loiasis in a Cameroonian village: a double-blind, placebo-controlled, crossover clinical trial of a three-day albendazole regimen.
Because of the life-threatening, post-treatment reactions that have occurred in patients with loiasis treated with ivermectin, evaluation of a short-course albendazole regimen was undertaken in a Loa-endemic region of Cameroon. In a placebo-controlled, double-blinded, crossover study, 99 subjects with microfilaremia (100-3,3837/mL) were assigned to receive albendazole (400 mg; n = 48) or placebo (n = 51) for three days and were followed for 180 days; at day 180, the groups were crossed over and followed for an additional six months. ⋯ Blood eosinophil and antifilarial IgG levels did not change significantly for either group, although antifilarial IgG4 levels did in the ALB/PLAC group at day 180. Most subjects continued to have elevations in microfilaremia, suggesting that more intensive regimens of albendazole will be necessary to reduce Loa microfilaremia to levels safe enough to allow for ivermectin use.

Historical ArticleAre multilateral malaria research and control programs the most successful? Lessons from the past 100 years in Africa.
Multilateral malaria research and control programs in Africa have regained prominence recently as bilateral assistance has diminished. The transnational nature of the threat and the need for inspired leadership, good coordination, and new discoveries to decrease the impact of the disease has led to the founding of the Multilateral Initiative on Malaria, the Roll Back Malaria Project, Global Fund for HIV, Tuberculosis and Malaria (Global Fund), the Medicines for Malaria Venture, and the Malaria Vaccine Initiative, among other groups. Historically, the most striking feature of malaria control and elimination activities was the connectedness and balance between malaria research and control especially, from 1892 to 1949. ⋯ However, excessive funding competition and failure of different programs to collaborate has resulted in poor communication and duplication of activities. The capacities of the African nations to conduct high-quality research and to coordinate control efforts are in great jeopardy. There is an urgent need for a non-partisan umbrella organ to coordinate and facilitate the network of alliances and programs in malaria research and control in Africa.

Case ReportsMyiasis in Kuwait: nosocomial infections caused by lucilia sericata and Megaselia scalaris.
Myiasis, the invasion of live human tissue by larvae of Diptera, is reported in the nasopharynx and a leg wound in two patients who were hospitalized for more than 72 hours in Mubarak Al-Kabeer Teaching Hospital in Kuwait City, Kuwait. On the fourth and fifth days after a 10-year-old Kuwaiti boy was admitted to the hospital intensive care unit in a bloodied and comatose state following a traffic accident, 'worms' that came out of his nostrils were fixed, cleared, and identified as second and third instar of Lucilia sericata (Diptera: Calliphoridae). ⋯ The larvae, in various stages of development, were identified as those of Megaselia scalaris (Diptera: Phoridae). Since the presence of larvae in both patients was recorded after a stay of at least 3-4 days in the hospital, by definition, these infestations are considered nosocomial.

Case ReportsFuniculitis due to Schistosoma haematobium: uncommon diagnosis using parasitologic analysis of semen.
Schistosomal funiculitis is one of the rare localizations of longstanding chronic infection with schistosomiasis. We report a case of a 24-year-old-man who experienced iliac fossa pain and weight loss eight years after his last trip to Mali. Clinical diagnosis of lesions in the genitourinary tract due to schistosomiasis and biologic analysis are required to diagnose this uncommon localization of schistosomiasis.
