Revista Cubana de Medicina , 2002,
Abstract: 6 cases of a family from a rural area with history of ingestion of wild watercress were studied to explain our clinical and therapeutic observations on this infection. symptoms of astenia, pain on the right hypochondrium, fever and hepatomegaly were observed some weeks after the ingestion. white blood cell count, global count of eosinophils, aminotranspherasa, alkaline phosphatasa, surface antigen, anti hvc, serodiagnosis for fasciola (indirect elisa), serial stools, biliary drainage, laparoscopy, liver biopsy and transduodenal cholangiopancreatography were performed. only the case of a child was studied by laboratory tests. an elevated global account of eosinophils was found in all cases. eggs of fasciola were detected in 2 cases: one in stools and the other in bilis. the presence of lesions of larva migrans visceral on the liver surface that behaved histologically as granulomas was demonstrated by laparoscopy. transduodenal cholangiopancreatography proved to be a useful method in the diagnosis and treatment of some cases. treatment with emetine and prazicuantel was indistinctly indicated.

Abstract: Se estudiaron 6 casos de una familia procedente del área rural, con antecedentes de ingestión de berro silvestre, para exponer nuestras observaciones clínicas y terapéuticas sobre esta infección. Se observó que unas semanas más tarde a la ingestión se presentaron síntomas de astenia, dolor en hipocondrio derecho, fiebre, hepatomegalia. Se realizó leucograma, recuento global de eosinófilos, aminotransferasas, fosfatasa alcalina, antígeno de superficie, anti HVC, serodiagnóstico para fasciola (ELISA indirecto), heces fecales seriadas, drenaje biliar, laparoscopia y biopsia hepática y colangiopancreatografía transduodenal. Se estudió solamente mediante exámenes de laboratorio el caso de un ni o. Se halló un recuento global de eosinófilos elevado en todos los casos. Se detectaron huevos de fasciola en 2 casos: uno en heces fecales y otro, en bilis. Se demostró, mediante laparoscopia, la presencia de lesiones de larva migrans visceral en la superficie hepática, que se comportaron histológicamente como granulomas. La colangiopancreatografía transduodenal resultó un método útil en el diagnóstico y tratamiento de algunos casos. Se indicó tratamiento con emetina y prazicuantel indistintamente. 6 cases of a family from a rural area with history of ingestion of wild watercress were studied to explain our clinical and therapeutic observations on this infection.

Revista Cubana de Medicina Tropical , 2011,
Abstract: Introducción: las variantes polimórficas del receptor FcgR IIa han sido asociadas con la susceptibilidad a padecer diferentes enfermedades infecciosas. Recientemente se reportó la asociación entre el polimorfismo de este receptor y la susceptibilidad a padecer la fiebre hemorrágica por dengue. Objetivos: explorar si la asociación a la susceptibilidad o protección de las variantes homocigóticas del receptor, pudieran estar relacionadas además, con los títulos de IgG y la exposición a diferente número de infecciones. Métodos: se hizo un estudio de tipo analítico retrospectivo a individuos infectados por virus dengue 4 en Ciudad de La Habana durante la epidemia de 2006, que se contactaron en 2008. Se reclutó un total de 97 individuos, de los cuales 68 habían padecido fiebre dengue y 29 fiebre hemorrágica de dengue.Se les extrajo una muestra de 10 mL de sangre total en anticoagulante que se empleó en el aislamiento de ADN. Se determinó el polimorfismo genético del receptor FcgRIIa, los títulos de anticuerpos totales IgG anti-dengue y el antecedente de infección por dengue. Resultados: se evidenció, de modo interesante, una relación directamente proporcional y muy significativa (p< 0,0001) entre los altos títulos de IgG anti-dengue con el número de infecciones padecidas. Este comportamiento fue característico en los individuos con la variante homocigótica HH. Conclusiones: al parecer, en aquellos individuos con polimorfismo para el receptor FcgRIIa-H/H podría haber una tendencia a la no eliminación de los anticuerpos IgG a través del FcgRIIa, la cual está asociada con el número de infecciones. Introduction: polymorphic variants of FcgRIIa receptor have been associated to susceptibility to develop several infectious diseases. The relationship between the polymorphism of this receptor and the susceptibility to dengue hemorrhagic fever was recently reported. Objectives: to explore whether the association of the homocygotic variants of the receptor to susceptibility to or protection from a disease could be also related with the IgG antibody titters and the exposure to a number of infections. Methods: a retrospective analytical study was performed on individuals who had been infected with the dengue virus 4 during the 2006 epidemic in the City of Havana and were tracked down in 2008. A total number of 97 individuals were recruited of whom 68 had suffered dengue fever and 29 had had dengue hemorrhagic fever. A 10 mL blood sample was taken from each of them and then placed in EDTA anticoagulant for DNA isolation and 5ml placed in dry tubes to obtain serum. The gene

Abstract: cutaneous metastasis of the digestive tract are infrequent lesions appearing in patients with advanced disease. most of these patients have been already operated of their primary tumour. lesions are variable in aspect, arising de novo and evolving with rapid growth. they usually lie in the trunk or lower extremities thus facilitating an early diagnosis and management with simple extirpation and direct closure. a case-report of a patient with advanced colonic cancer is here presented. at admission he presented a cutaneous matastasic lesion in the right cheek; it was a 6 cm ulcerated, bad -smelling lesion which needed daily dressings affecting patient's normal life. the lesion was removed using successfully a submental flap as coverage. the submental flap provides a very similar tissue to facial defects, leaving no donor area sequelae which is in addition well hidden, being consequently a good tool for midsize facial defects.

Abstract: the behaviour of the oviposition of pregnant females of aedes aegypti in the presence of biological agents: macrocyclops albidus (copepoda: cyclopoidea) or bacillus thuringiensis var. israelensis (bti) was evaluated under lab conditions. recipients containing 225 ml of dechlorinated water were placed for oviposition with three variants: water with copepods, water with bti, and water. the average of eggs layed in the recipients with copepods and bti were 1 227.9 and 1 200.8, respectively, a figure higher than the 887.4 eggs of the recipient containing only water, although the differences observed were not statistically significant (p >0.05). the oviposotion activity index (oai) estimated showed values over 0 for copepods and for bti, which indicated that females did not avoid to deposit their eggs in these recipients. the results suggested that in nature, these recipients with biological controllers may be oviposition sites for pregnant females of aedes aegypti, which may have positive implications on its effectiveness to control this vector.

Abstract: se evaluó el efecto patogénico de 3 nematodos parásitos romanomermis culicivorax ross y smith, 1976, romanomermis iyengari welch, 1964 y strelkovimermis spiculatus poinar y camino, 1986, a diferentes dosis de aplicación, en larvas de aedes aegypti linnaeus, 1762. para cada unidad experimental se utilizaron 100 larvas de ii estadio de este mosquito y se infestaron con nematodos preparasíticos de las 3 especies, en proporciones de 3:1, 5:1, 10:1, 15:1 y 20:1. las medias de infestación y las tasas de parasitismo aumentaron en la medida en que se incrementaron las dosis. a bajas densidades de nematodos (3 y 5 nematodos/larva) r. culicivorax resultó ser más efectivo al compararla con las otras especies, sin embargo con una proporción de 10:1 todos los nematodos provocaron 100 % de mortalidad, siendo s. spiculatus el nematodo que provocó las medias de infestación más altas. por esta razón, una proporción de 10:1 pudiera ser recomendada para que estos nematodos sean evaluados en condiciones naturales en recipientes artificiales no útiles como una alternativa biológica para el control de aedes aegypti.

Abstract: there are significant differences between the war and the disasters. despite the broad diversity of criteria son disasters, many authors include the war within the category of disaster. the same occurs with its classification, based on supposing that consequences for human communities suffering it be equivalent. we present a series of features to distinguishing between a war and a disaster. among them are included the purpose of a war that is to cause the greater damage possible in a determined population or community, and the impact differences on physical and mental health, where in the war is aggravated by obstacles imposed by the contending parts to make the health care tasks. in war the appropriate conditions to extend violence and to perpetuate it are created. we conclude that differences between a war and a disaster in relation with causes and consequences for health are greater than similarities presented by both phenomena, being two situations that must to be separately studied to avoid errors and confusion.
