Ultrastructural description of Ceratomyxa microlepis sp. nov. (Phylum Myxozoa): a parasite infecting the gall bladder of Hemiodus microlepis, a freshwater teleost from the Amazon River

A new ceratomyxid parasite was examined for taxonomic identification, upon being found infecting the gall bladder of Hemiodus microlepis (Teleostei: Hemiodontidae), a freshwater teleost collected from the Amazon River, Brazil. Light and transmission electron microscopy revealed elongated crescent-shaped spores constituted by two asymmetrical shell valves united along a straight sutural line, each possessing a lateral projection. The spores body measured 5.2 ± 0.4 µm (n = 25) in length and 35.5 ± 0.9 µm (n = 25) in total thickness. The lateral projections were asymmetric, one measuring 18.1 ± 0.5 µm (n = 25) in thickness and the other measuring 17.5 ± 0.5 µm (n = 25) in thickness. Two equal-sized subspherical polar capsules measuring 2.2 ± 0.3 µm in diameter were located at the same level, each possessing a polar filament with 5-6 coils. The sporoplasm was binucleate. Considering the morphometric data analyzed from the microscopic observations, as well as the host species and its geographical location, this paper describes a new myxosporean species, herein named Ceratomyxa microlepis sp. nov.; therefore representing the first description of a freshwater ceratomyxid from the South American region.

Myxidium volitans sp. nov., a parasite of the gallbladder of the fish, Dactylopterus volitans (Teleostei: Triglidae) from the Brazilian Atlantic coast: morphology and pathology

Myxidium volitans sp. nov. (Myxozoa: Myxidiidae) parasitizing the hypertrophied green-brownish gallbladder of the teleost Dactylopterus volitans, collected in the Atlantic coast near Niterói, Brazil was described based on ultrastructural studies. The spores were fusiform, sometimes slightly crescent-shaped on average 21.7 ± 0.3 µm (mean ± standard deviation) (n = 50) long and 5.6 ± 0.4 µm (n = 30) wide. The spore wall was thin and smooth, comprising two equally-sized valves joined by a hardly visible sutural ridge. Spores containing two pyriform polar capsules (PC) (5.0 ± 0.4 × 2.3 ± 0.3 µm) (n = 30) are situated in each extremity of the spore. The PC wall was composed of hyaline layer (0.20-0.29 µm thick) and by a thin external granular layer. Each PC contains a polar filament (PF) with irregular arrangements that was projected from its apical region to the bases of PC and coiled laterally from bases to the tip of PC. Some regular striations and S-like structures in the periphery of the PFs with four-five irregular sections were observed. Based on the spore morphology, ultrastructural differences and the specificity of the host we describe this parasite as a new myxosporidian, named M. volitans sp. nov.

Variação da ecogenicidade difusa em parênquima hepático homogêneo relacionada aos achados bioquímicos e hematológicos em cães

The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.

Perfil epidemiológico de la colelitiasis aguda en pacientes de 0 a 18 años en el Hospital Nacional de Niños Benjamín Bloom durante el período de Enero 2010 a Diciembre 2014

La Colelitiasis biliar se define como la presencia de material sólido, cálculos o lodo, en el tracto biliar, generalmente en la vesícula biliar. El concepto de enfermedad vesicular indica cambios funcionales y/o morfológicos (inflamación o fibrosis) en la vía biliar, secundarios al desarrollo de bilis con capacidad para formar cálculos o asociados a la litiasis vesicular. En el caso de nuestro estudio, definimos como cuadro agudo, el cuadro que se acompaña de dolor de inicio súbito, vómito, diarrea, y / o síntomas dispépticos, así como ictericia, que obligan a consultar de forma inmediata en un centro asistencial. El interés del pediatra por determinar la causa específica del dolor abdominal en niños, ha obligado a ampliar los conocimientos teóricos, a mejorar la sospecha clínica, a la identificación temprana de factores de riesgo, y la mejora en los manejos para la mayor supervivencia de niños con patología que predisponen a la colelitiasis biliar. Con el avance en las exploraciones ultrasonográficas, se ha descrito con mayor frecuencia casos de colelitiasis biliar en la edad pediátrica, con una incidencia mayor a la esperada hasta hace algunos años, para los diferentes grupos poblacionales.

Identificación bacteriana en pacientes con colecistitis aguda del servicio de cirugía Hospital Vicente Corral Moscoso, Cuenca 2001

Se realizó un estudio de tipo prospectivo descriptivo, con el objeto de identificar la presencia o no de gérmenes en la bilis de pacientes que presentaron colicistitis aguda, que acudieron al servicio de emergencia y consulta externa de Hospital Vicente Corral Moscoso. Durante el período de Enero a Mayo del 2001. Determinándose que esta patología al ser de inicio súbito, fue tratada en su mayoría antes de las 72 horas, siendo más frecuente en el sexo femenino, y con mayor incidencia entre la tercera y quinta década de la vida, de quienes se obtuvo bilis mediante punción de la vesícula biliar durante la colecistectomía. Luego se procedió a realizar Tinción de Gram y cultivos, los gérmenes encontrados en la tinción en fresco, fueron en su gran mayoría Gram negativos. Siendo además la E. Coli el gérmen más frecuente en medio de cultivo

Antibióticos profilácticos en colecistectomía electiva

Se estudian de manera randomizada tres grupos de veinte pacientes cada uno, sometidos a colecistectomía electiva y que no tuvieron ninguno de los factores asociados con bactibilia. El primer grupo no recibió antibióticos profilácticos, el segundo y tercer grupos recibieron 3 dosis intravenosas de 1 gr. De ampicilina y Cefazolina respectivamente. Se controló la presencia de infección de la herida quirúrgica hasta el momento de retirar los puntos. Se obtuvo la vesícula biliar, obteniéndose 23,3de cultivos positivos, siendo el germen más frecuentemente encontrado el E. Coli
