En 1997, se desarrolló un proyecto nacional de adiestramiento integral para el diagnóstico de las parasitosis intestinales, el que incluyó 4 cursos; uno com carácter nacional, y otros 3 en las provincias centrales, orientales y occidentales. Al comparar los errores diagnósticos, vimos que Cryptosporidium parvum, Cyclospora cayetanensis y los leucocitos mostraron un porcentaje significativamente menor de fallas después del curso que al comienzo (p < 0,01), al igual que con Entamoeba histolytica/E. dispar y Chilomastix mesnilii (p < 0,05). Entre los helmintos, Taenia sp., Fasciola hepatica y los ancylostomídeos redujeron significativamente el número de fallas (p < 0,01). En el resto de las especies se encontraron muy pocos errores, y los porcentajes de fallas no variaron al finalizar los cursos (p > 0,05). Por otra parte, al comparar las medias de las puntuaciones antes y después de los cursos, se encontró un aumento significativo en el curso de las provincias centrales (p

The article presents the author's views on a study conducted by them which was related to the diagnosis of neurocysticercosis. As mentioned, NCC occurs when a cyst starts developing in the brain. He further states that the study was conducted on a group of patients suffering from epilepsy. He also mentions that the study was conducted by two methods including by detection of antibodies and by detection of circulating cysticercal antigen.

Introduction: the infection caused by Paracapillaria philippinensis (Capillaria philippinensis) is clinically characterized as a progressive enteric illness with massive loss of proteins and a malabsorption syndrome that may become fatal. OBJECTlVE: the first report in Cuba of human infection with P. philippinensis., Methods: the case of a Cuban male patient aged 21 years from the City of Havana, who had never been abroad, was described. This young man was admitted to the hospital because after having eaten one breadcrumb-covered fish, he started having diarrheic episodes that progressively increased up to more than 15 abundant diarrheas per day, without phlegm or blood, and a clinical picture of severe malnutrition and general symptoms of intensive asthenia and anorexia., Results: the lab diagnosis confirmed the presence of P. philippinensis eggs in feces., Conclusions: the clinical features of the patient and the finding of moderate eosinophilia in the hematological study agreed with published information. As far as we know, this is the first finding of a human infection caused by P. philippinensis in Cuba, and in the American continent as well. The epidemiological alert on the possible emergence of new cases of this parasitic infection in our geographic zone is important, mainly in those places where the habit of eating raw or undercooked fish is part of the local culture.

First case report of Mammomonogamus (Syngamus) laryngeus human infection in Colombia Parasitic nematodes of the genus Mammomonogamus affect the respiratory tract of domestic mammals. The male and female of M. laryngeus remain in permanent copula so that the pair appears as a "Y'. To date, a few more than 100 cases of human infections by this parasite have been reported in the biomedical literature. This report describes the first infected patient in Colombia. He had a persistent and productive cough and after an episode of coughing a pair of worms were expelled in sputum with total clinical recovery. Since there is scant clinical information about this parasite, this report includes a description of the adult worms, a summary of the epidemiology and the clinical manifestations in humans. Photographs are presented to facilitate future identification by morphological characteristics.

A study of 456 children aged 1-5 from 4 day care centers of San Miguel del Padron municipality was conducted in 1998, to evaluate the diagnosis of Giardia lamblia and other intestinal protozoa by using comparatively the coproparasitological diagnostic methods of direct examination and Ritchie's concentration technique or formol-ether. Besides, a therapeutical trial was developed with tinidazole and albendazole for treating the infection caused by G lamblia. Ritchie's concentration technique was more effective than the microscopic direct examination for diagnosing Giardia lamblia, Entamoeba histolytical/Entamoeba dispar and Cyclospora cayetanensis. It was demonstratyed that the serial examination was more sensitive than the analysis of just one sample (p< 0.01). On the other hand, tinidazole proved to be more efficient than albendazole to treat the infection produced by G. lamblia, with a greater cure percentage (72 % vs. 334.6%), (p < 0.01).

We conducted a longitudinal study on giardiasis in three daycare centers in Havana City for a period of 18 months and described a group of children with a "predisposition" or tendency towards re-infection with Giardia lamblia. This group was found to be more frequently associated with clinical symptoms such as diarrhea. A case-control study was designed to determine whether socioeconomic factors and hygiene were associated with this phenomenon. We found no differences between the groups with regard to overcrowding rates, number of persons per bed, absence of certain electric appliances, mother's schooling, or mean family income. However, there were proportionally more fathers with less than complete secondary education among cases as compared to controls. In addition, we found no differences in lack of hand-washing before eating and after defecation; however, we found a higher percentage of families who washed vegetables insufficiently among predisposed children. Finally, a lower percentage of families with predisposed children boiled their water. Our results demonstrate the important role of water as a vehicle for transmission of giardiasis and the importance of various epidemiologic factors.
