Cost-effectiveness of triple drug administration (TDA) with praziquantel, ivermectin and albendazole for the prevention of neglected tropical diseases in Nigeria.

Onchocerciasis, lymphatic filariasis (LF), schistosomiasis and soil transmitted, helminthiasis (STH) are all co-endemic in Nigeria. Annual mass drug administration (MDA) with ivermectin (for onchocerciasis), albendazole (for STH and with ivermectin for LF) and praziquantel (for schistosomiasis) is the WHO-recommended treatment strategy for preventive chemotherapy. Separate delivery rounds for distribution of these drugs have been the usual approach to MDA. All three drugs, however, have now been shown to be clinically and programmatically safe for co-administration with what has come to be known as triple drug administration (TDA). We examined the cost savings of converting from separate delivery rounds to TDA in two states in Nigeria. In 2008, eight local government areas received a single round of ivermectin with albendazole followed at least 1 week later by a single round of praziquantel to school-aged children. The following year, a single round was administered with TDA. The number of treated individuals was essentially unchanged during both years (1,301,864 in 2008 and 1,297,509 in 2009) and no change in adverse events was reported. The total programmatic costs for the MDA, not including drug and overhead costs, reduced by 41% from $123,624 to $72,870. Cost savings were limited in larger populations due to economies of scale. TDA is recommended for mature MDA.

Protein S deficiency. Description of a case associated with chronic inflammatory bowel disease.

Thrombotic disease is one of the most relevant clinical problems for morbility and mortality. We can differentiate congenital and acquired forms. In this short communication we describe 1 case observed by us that seems interesting for the association of a congenital and acquired form [Protein S deficiency and inflammatory bowel disease (IBD)] and for the dramatic events suffered before receiving a complete diagnosis and therapy, indicating the importance of recollection of information from the patients, starting from anamnestic data.

[Eosinophilia and Strongyloides stercoralis infestation: case report] / Eosinofilia e infestazione da Strongyloides stercoralis: caso clinico.

Authors report about a case of Strongyloides stercoralis infestation. The patient, a 65-year old man, presented with a clinical history of eosinophilia but without symptomatology. Several stool specimen showed the presence of rhabditiform larvae of S. stercoralis and after therapy the patient had a normalization of the white blood ceIls count. The authors wish to point out the importance of the diagnosis because a change in immune status may convert a previously asymptomatic infection to hyperinfection.

Regional cerebral mode transit time and the derivative of the regional cerebral function recorded for intravenous administration of a non-diffusible tracer.

The meaning of the time from origin to first peak and from peak to peak of the derivative of the regional cerebral functions recorded after intravenous administration of a non-diffusible tracer is analyzed. Data obtained by cerebral and cardiac monitoring and evaluation of both times in patients with carotid thrombosis, indicates that the time from origin to first peak may be a better estimate of regional cerebral mode transit time than the time from peak to peak.
