RESUMO

La atrofodermia idiopática de Pasini y Pierini es una entidad poco frecuente y de etiología aún no esclarecida, se presenta con una frecuencia hasta seis veces mayor en mujeres que en hombres y una posible asociación con la esclerodermia localizada (morfea). Paciente femenina de 30 años, quien consultó por una lesión asintomática de dos años de evolución en el glúteo izquierdo. En el examen físico se evidenció una placa ovalada, deprimida y acrómica en su centro, que mide cinco por diez centímetros. La paciente había sido tratada previamente con múltiples terapias tópicas sin obtener mejoría clínica. Se realizó la biopsia de piel que demostraba cambios mínimos en epidermis, homogenización y adelgazamiento de colágeno sin afección de anexos. Se hizo correlación con los hallazgos clínicos y se decidió iniciar tratamiento con esteroides intralesionales de alta potencia (acetónido de triamcinolona). Posterior a la administración de dos aplicaciones del medicamento, con cuatro semanas de diferencia entre ellas, se evidenció la resolución completa de la dermatosis. Un mes después de la última dosis la paciente no mostró recidivas


diopathic atrophoderma of Pasini and Pierini is a rare entity of unclear etiology, occurring as much as six times more frequently in women than in men, with a possible association with localized scleroderma (morphea). It is about a 30 years old woman who consulted with an asymptomatic lesion of two years of evolution on the left gluteal region. Physical examination revealed an oval plaque, depressed and acromic in its center, measuring five by ten centimeters. A 30 years old female patient who consulted about an asymptomatic lesion of two years of evolution on the left gluteal region. Physical examination revealed an oval plaque, depressed and acromic in its center, measuring five by ten centimeters. The patient was previously treated with multiple topical therapies without clinical improvement.Skin biopsy showed minimal changes in the epidermis, homogenization, and thinning of the collagen without adnexal involvement. After a correlation was made with the clinical findings, starting treatment with high-potency intralesional steroids (triamcinolone acetonide) was recommended. After administering two applications of the drug, four weeks apart, the complete resolution of the dermatosis was evidenced. One month after the last dose, the patient showed no recurrence

RESUMO

Resumen Balantidium coli es el único miembro de la familia Balantidiidae capaz de producir infección en seres humanos. Presentamos un caso en un hombre de 43 años que ingresa para corrección quirúrgica de hernia ventral durante la cual se realizó apendicetomía profiláctica. En el estudio histopatológico se observó apéndice cecal con arquitectura conservada, sin la presencia de apendicitis ni periapendicitis. En la luz se reconocieron estructuras grandes (aproximado de 50 μm) redondas con citoplasma amplio con vacuolas grandes, cilias periféricas y núcleos densos, los cuales correspondieron a trofozoitos de Balantidium coli.


Abstract Balantidium coli is the only member of the Balantidiiae family capable of infecting human beings. We present one in a 43 years-old male admitted for a surgical co rrection of an incisional hernia with prophylactic appendicectomy. Histopathological findings reported the cecal appendix within normal architecture, appendicitis and peri-appendicitis free. At the lumen big, rounded shape structures (aprox. 50 mm) were visible with broad cytoplasm, big vacuoles, peripheral cilia and dense nucleus, corresponding to Balantidium coli trophozoites.

RESUMO

The use of probiotics has gained acceptance in aquaculture, particularly in maintaining water quality and enhancing growth in organisms. This study analyzed the effect of the commercial (EM TM, Japan) natural product composed by (Rhodopseudomonas palustris, Lactobacillus plantarum, Lactobacillus casei and Saccharomyces cerevisiae) added to the water, in order to determine its effect in water quality, sediment and growth of L. vannamei under intensive culture. The evaluation included three treatments with a weekly addition of EM: i) tanks without probiotics (C), ii) tanks with a dose of 4L/ha (EM1) and iii) tanks with a dose of 10L/ha (EM2). The treatment C was carried out three times, while treatments EM1 and EM2 were carried out four times. A total of 4 350 shrimps were measured for total length and weight, to calculate total and porcentual weight gain, daily weight gain, specific growth rate (TCE), and food conversion factor (FCA); besides, the survival rate was estimated. The use of probiotics allowed a shorter harvest time in treatments EM1 (90d) and EM2 (105d) with relation to the treatment C (120d). Treatments EM1 and EM2 were within the recommended intervals for culture, with respect to treatment C. The use of probiotic bacteria significantly regulated pH (EM1, 8.03±0.33; EM2, 7.77±0.22; C, 9.08±0.35) and reduced nitrate concentration (EM1, 0.64±0.25mg/L; EM2, 0.39±0.26mg/L; C, 0.71mg/L). Water pH mostly explained the variance with respect to the treatments. Treatment EM2 presented the greatest removal of organic matter (1.77±0.45%), whereas the contents of extractable phosphorus increased significantly in treatment EM1 with 21.6±7.99mg/kg and in treatment EM2 with 21.6±8.45mg/kg with control relation (14.3±5.47). The shrimp growth was influenced by dissolved oxygen, salinity and pH in the sediment, establishing that salinity was the most important variable in the weight with a negative association. Treatment EM1 recorded an improved TCE (2.69±0.35%/d) and FCA (1.46±0.20) with relation to the control treatment (TCE, 1.88±0.25%/d; FCA, 2.13±0.48). Survival was significantly greater in treatments containing probiotics with 61±8.76% and 60±10.5% for EM1 and EM2, respectively. This study indicated the positive effect obtained with the use of this commercial probiotic, to improve culture conditions and growth parameters in an intensive culture of L. vannamei.


Los probióticos han ganado aceptación en la acuicultura para mantener la calidad del agua y aumentar el crecimiento de los organismos. En este estudio se analizó el efecto de una mezcla comercial de microorganismos eficientes (EM) (Rhodopseudomonas palustris, Lactobacillus plantarum, Lactobacillus casei y Saccharomyces cerevisiae) sobre la calidad del agua, sedimento y el crecimiento en un cultivo intensivo de camarón L. vannamei. La evaluación consistió en tres tratamientos: i) estanques sin EM (C), ii) estanques con dosis de 4L/ha (EM1) y iii) estanques con dosis de 10L/ha (EM2). Los resultados demostraron menor tiempo de cosecha en los tratamientos EM1 (90d) y EM2 (105d). Los tratamientos EM1 y EM2 mantuvieron significativamente regulados los valores del pH (EM1, 8.03±0.33; EM2, 7.77±0.22) y redujeron las concentraciones de nitrato (EM1, 0.64±0.25mg/L; EM2, 0.39±0.26mg/L). El tratamiento EM2 presentó la mayor remoción de materia orgánica (1.77±0.45%). El tratamiento EM1 mejoró la TCE (2.69±0.35%/d) y FCA (1.46±0.20). Los tratamientos EM1 y EM2 presentaron mayor supervivencia con 61±8.76% y 60±10.5%, respectivamente. Este estudio demostró el efecto benéfico del uso de la mezcla comercial en los parámetros ambientales y de crecimiento en un cultivo intensivo de L. vannamei.

RESUMO

Human abdominal angiostrongyliasis is a zoonotic disease caused by ingestion of the L3 larvae of Angiostrongylus costaricensis. The human infection gives rise to a pathological condition characterized by acute abdominal pain, secondary to an inflammatory granulomatous reaction, marked eosinophilia and eosinophilic vasculitis. Most commonly this disease is limited to intestinal location, primary ileocecal, affecting the mesenteric arterial branches and intestinal walls. We present one of the few cases reported around the world with simultaneous involvement of the intestines and liver, including proved presence of nematodes inside the hepatic arteriole.


La enfermedad conocida como angiostrongiliasis abdominal humana es una zoonosis causada por la ingestión del estadio larval L3 de Angiostrongylus costaricensis. En el ser humano, esta infección provoca un estado patológico caracterizado por dolor abdominal agudo, secundario a una reacción inflamatoria granulomatosa; eosinofilia marcada y vasculitis eosinofílica. Comúnmente el cuadro se encuentra limitado a una localización intestinal, predominantemente ileocecal, que compromete las ramas de la arteria mesentérica y la pared intestinal. Presentamos uno de los pocos casos reportados alrededor del mundo con hallazgos simultáneos en intestino e hígado; se incluye la demostración histológica del nemátodo dentro de la arteriola hepática.

RESUMO

Estudio filogenético de los géneros de Lithinini de Sudamérica Austral (Lepidoptera, Geometridae): una nueva clasificación. Se evalúa la taxonomía de la tribu Lithinini de Sudamérica Austral sobre la base de un análisis filogenético. Para el análisis se utilizó a Catophoenissa como grupo externo. Se usaron dos aproximaciones filogenéticas para evaluar las relaciones de parentesco: 1) criterio de parsimonia; e 2) inferencia bayesiana. El análisis de parsimonia se realizó a través del programa PAUP y el análisis bayesiano con cadenas de Markov y Monte Carlo a través del programa BayesPhylogenies. Los resultados generados a partir de la hipótesis filogenética permiten proponer una nueva taxonomía para los Lithinini de Sudamérica Austral. Los géneros validos son: Asestra Warren, Acauro Rindge, Calta Rindge, Euclidiodes Warren, Franciscoia Orfila y Schajovskoy, Incalvertia Bartlett-Calvert, Lacaria Orfila y Schajovskoy, Laneco Rindge, Maeandrogonaria Butler, Martindoelloia Orfila y Schajovskoy, Nucara Rindge, Odontothera Butler, Proteopharmacis Warren, Psilaspilates Butler, Rhinoligia Warren, Tanagridia Butler. Los principales cambios respecto de ordenamientos taxonómicos previos son: 1) Yalpa Rindge, es tratado como sinónimo junior de Odontothera. 2) El género Rhinoligia Warren es incorporado a los Lithinini; 3) Se reafirma que Siopla Rindge es sinónimo junior de Asestra, Yapoma Rindge y Duraglia Rindge son sinónimos de Euclidiodes Warren, mientras que Callemo Rindge y Guara Rindge son sinónimos de Tanagridia; 4) Los géneros Calta Rindge, Incalvertia Rindge, Odontothera Butler y Proteopharmacis Warren, sinonimizados por Pitkin, son redefinidos, revalidados e incorporados a la tribu Lithinini. Se describe una nueva especie para el género Franciscoia, F. ediliae Parra. Se incluye un catálogo con los géneros y especies de la tribu de la región, más las figuras de los adultos y genitalias de las principales especies.


In this work we evaluate the taxonomy of the Lithinini of Austral South America based on a phylogenetic analysis. In our analysis we used outgroup Catophoenissa. Two approaches were used to evaluate phylogenetic relationships: 1) parsimony criterion, and 2) Bayesian inference. Parsimony analysis was conducted in PAUP software, and Bayesian analysis with Markov chains Monte Carlo using the BayesPhylogenies software. Our results based on the phylogenetic hypothesis suggest a new taxonomic order for Austral American Lithinini. The valid genera are: Asestra Warren, Acauro Rindge, Calta Rindge, Euclidiodes Warren, Franciscoia Orfila and Schajovskoy, Incalvertia Bartlett-Calvert, Lacaria Orfila and Schajovskoy, Laneco Rindge, Maeandrogonaria Butler, Martindoelloia Orfila and Schajovskoy, Nucara Rindge, Odontothera Butler, Proteopharmacis Warren, Psilaspilates Butler, Rhinoligia Warren and Tanagridia Butler. The main changes with respect to the previous taxonomic order are: 1) Yalpa Rindge is the synonymous junior of Odontothera; 2) the genus Rhinoligia Warren is incorporated into the Lithinini; 3) while our analysis reaffirms that Siopla Rindge is junior synonym of Asestra, Yapoma Rindge and Duraglia Rindge are synonymous of Euclidiodes Warren, while Callemo Rindge and Guara Rindge are synonymous of Tanagridia; 4) the genus Calta Rindge, Incalvertia Rindge, Odontothera Butler and Proteopharmacis Warren, synonymized by Pitkin, are redefined, revalidated and incorporated into the Lithinini tribe. A new species for the genus Franciscoia, F. ediliae Parra is described. A catalogue of the genera and species of the tribe in the region, and the figures of adults and genitalia of some species are included.

RESUMO

Environmental changes caused by logging in a mangrove swamp were studied in Barra de Tecoanapa, Guerrero, Mexico. Original forest included Rhizophora mangle, Laguncularia racemosa, Avicennia germinans and halophytic vegetation, and produced wood (164.03 m3/ha) and organic matter (3.9 g/m2/day). A total of 3.5 tons of wood per year were harvested from this area. Later, an average of 2,555 kg of maize per planting cycle were obtained (market value of 88 USD). Succession when the area was abandoned included strictly facultative and glycophyte halophytes (16 families, Cyperaceae and Poaceae were the best represented). After logging, temperatures increased 13 degrees C in the soil and 11 degrees C in the air, whereas salinity reached 52 psu in the dry season. These modified soil color and sand content increased from 42.6 to 63.4. Logging was deleterious to species, habitat, biogeochemical and biological cycles, organic matter production, seeds, young plants, genetic exchange conservation of soil and its fertility, coastal protection, and aesthetic value; 3,000 m2 had eroded as the river advanced towards the deforested area (the cost/benefit analysis showed a ratio of 246:1). There was long-term economic loss for the community and only 30 of the site has recovered after five years.
