Abstract

This study consists of a broad review on what is known and what should be improved regarding knowledge of Chagas disease, not only through analysis on the main studies published on the topics discussed, but to a large extent based on experience of this subject, acquired over the past 50 years (1961-2011). Among the subjects covered, we highlight the pathogenesis and evolution of infection by Trypanosoma cruzi, drugs in use and new strategies for treating Chagas disease; the serological tests for the diagnosis and the controls of cure the infection; the regional variations in prevalence, morbidity and response to treatment of the disease; the importance of metacyclogenesis of T. cruzi in different species of triatomines and its capacity to transmit Chagas infection; the risks of adaptation of wild triatomines to human dwellings; the morbidity and need for a surveillance and control program for Chagas disease in the Amazon region and the need to prioritize initiatives for controlling Chagas disease in Latin America and Mexico and in non-endemic countries, which is today a major international dilemma. Finally, we raise the need for to create a new initiative for controlling Chagas disease in the Gran Chaco, which involves parts of Argentina, Bolivia and Paraguay.

Abstract

INTRODUCTION:

Tularemia is an uncommon but potentially fatal zoonosis. А second outbreak of tularemia in Bulgaria, about 40 years after the first, occurred in 1997 in two western regions, near the Serbian border. In 2003 tularemia reemerged in the same foci. This retrospective study aimed to evaluate the clinical characteristics and the efficacy of antibiotic therapy in a tularemia resurgence in the Slivnitza region in 2003-2004.

METHODOLOGY:

A total of 26 cases were evaluated. Using medical records, the following data were collected for all patients: symptoms, physical signs, and microbiology results of agglutination tests, cultures and PCR assays.

RESULTS:

Twenty-four of 26 suspected tularemia patients were laboratory confirmed by agglutination test and/or culture. Fifteen (57.7%) patients had clinical presentation compatible with oropharyngeal, 8 (30.8%) with glandular, and 3 (11.5%) with oculoglandular tularemia. The most frequent symptoms were swollen neck (84.6%) and sore throat (76.9%). Lymphadenopathy (100%) was the most common finding. Francisella tularensis (F. tularensis) was detected by PCR, providing a definitive diagnosis in 82.3% of the cases. All the patients were treated with antibiotics considered effective against F. tularensis; however, therapeutic failure was observed in 23.1% of the cases, which was related to a delay in the initiation of antibiotics.

CONCLUSION:

The tularemia outbreak in west Bulgaria near the Serbian border was probably food-borne, associated with a surge in the rodent population. The oropharyngeal form was the most common. Although the disease runs a benign course, late initiation of antimicrobial therapy might delay complete recovery.

Gastritis sifilítica: una etiología a tener en cuenta

Enf Inf & Microbiol. Clin Feb. 2012 V.30 N.2 P.105-107

Carta

Sr. Editor:

En la última década se observa cómo la incidencia de sífilis está en aumento y en la actualidad constituye un importante problema de salud pública en nuestro medio. La tasa de incidencia en España pasó de 2,57 en 1995 a 5,33 por 100.000 habitantes en el año 2009 y desde el año 2004 los casos de sífilis superan, por primera vez, a los de infección gonocócica. Al igual que en otros países, este aumento de casos afecta en particular a hombres que mantienen relaciones sexuales con hombres (HSH) y en este colectivo, va de la mano de la infección por el virus de la inmunodeficiencia humana (VIH) en muchos casos…
