Report of a bite by the South American colubrid snake Philodryas olfersii latirostris (Squamata: Colubridae)

Acta Herpetologica , 2007,
Abstract: Following the bite of Philodryas olfersii latirostris Cope, 1862, a 29-year-old male herpetologist developed localized and burning pain, and minimal bleeding from the puncture marks of posterior maxillary teeth, which subsided rapidly. The victim developed no other local signs or symptoms. After few days the victim presented persistent severe rotatory dizziness, nausea, and vomiting. On examination his hearing was normal. Neurological exam was otherwise normal. The patient had acute vertiginous symptoms but had no associated neurological signs. Computed tomography did not show abnormality. A diagnosis of labyrinthine syndrome was made. It was treated conservatively, and the patient recovered uneventfully. It was assumed as an effect of ophitoxemia. This case may be regarded as an unusual presentation of systemic envenoming following a human bite by Philodryas olfersii latirostris.

Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2010, DOI: 10.1590/S0102-09352010000600010
Abstract: the therapeutic effects of argentine propolis ear drop formulation on canine otitis externa were evaluated. forty-eight dogs with symptoms of otitis externa were randomly assigned to double-blinded, controlled clinical trial to evaluate the efficacy of topical formulation with propolis versus a topical placebo in the treatment of otitis externa. the propolis preparation and placebo were administrated into both external ear canals, twice daily for 14 days. throughout the study, clinical examination and microbiological analysis of dogs ear exudates were made. the most frequent microorganisms isolated in culture media were: malassezia pachydermatis (54.2%), staphylococcus aureus (43.8%), coagulase-negative staphylococcus (25.0%), pseudomonas aeruginosa (20.8%), candida albicans (18.8%), proteus mirabilis (16.7%), streptococcus spp. (16.7%), enteroccocus faecalis (12.5%), escherichia coli (12.5%), staphylococcus intermedius (6.3%), klebsiella spp. (4.2%), andcandida glabrata (2.1%). whereas the control group did not recover from the infectious ear disease, the propolis preparation exhibited antimicrobial activity against most of the microorganisms isolated from samples of the treated group. in addition, no propolis-adverse effects were observed. this allowed propolis-treated patients to show a significant improvement of the clinical parameters. thus, this new argentine propolis ear drop formulation may be used for topical treatment of otitis externa in dogs.

Myriam Campbell B,Myriam Ferreiro C.,Juan Tordecilla C.,Pilar Joannon S.
Revista chilena de pediatría , 1999,
Abstract: Resumen Objetivo: El objetivo es comunicar los hallazgos al diagnóstico en ni os con LLA, describiendo las formas de presentación que permiten sospechar esta entidad. Pacientes y método: revisión retrospectiva de las fichas clínicas de 100 ni os tratados en el Hospital Roberto del Río entre enero 1992 y junio 1998. Resultados: 62% varones, incidencia peak entre 1-6 a os (60%). El tiempo medio antes del diagnóstico fue 2,5 semanas. Los síntomas más frecuentes son compromiso del estado general (81%), palidez (66%), fiebre (60%), dolor óseo (30%) y púrpura (24%). Los hallazgos más comunes en el examen físico: hepatomegalia (71%), adenomegalia (71%), esplenomegalia (24%). El hemograma es siempre anormal con anemia (90%), trombocitopenia (72%), neutropenia (62%) y/o linfoblastos (67%). Muchos pacientes debutan con una mezcla de síndromes (anémico, febril, tumoral, dolor óseo) y sólo 23 fueron monosintomáticos (todos con neutropenia). Conclusión: Una anamnesis y examen físico detallados, junto a una adecuada interpretación del hemograma, permiten al pediatra sospechar esta enfermedad, la que actualmente tiene alta probabilidad de curación. Acute lymphoblastic leukaemia (ALL). Characteristics at diagnosis in 100 patients The objective is to report the features at diagnosis in children with ALL, describing the different presentations that allows the clinician to suspect this entity. Patients and methods: retrospective analysis of the clinical records of patients treated at the Roberto del Río Hospital between january 1992 and june 1998. Results: 62% male, peak age incidence was between 1-6 years (60%). The median time before diagnosis of ALL was 2.5 weeks. The most frequent symptoms were weakness (81%), pallor (66%), fever (60%), bone pain (30%) and purpura (24%). The most common physical findings were hepatomegaly (71%), lymphadenopathy (71%) and splenomegaly (24%). The blood analysis was always abnormal: anaemia (90%), thrombocytopenia (72%), neutropenia (62%) and circulating lymphoblasts (67%). Most patients presented with a mixture of syndromes (anaemic, fever, tumoral, bone pain), only 23 were momosymptomatic (all had neutropenia). Conclusion: a careful history and physical examination with a detailed interpretation of the peripheral blood count allows paediatricians to suspect this disease that today has a high probability of cure.

Revista chilena de pediatría , 1999,
Abstract: Objetivo. Describir las características clínicas de ni os con tumor abdominal. Pacientes y Método. Se revisaron las fichas de 50 pacientes tratados en el Hospital Roberto del Río entre diciembre 1988 y abril de 1999. Resultados: 52% fueron varones, 46% con edad 1 a 5 a os, el motivo de consulta fue dolor (40%) y hallazgo de tumor (32%). El examen físico mostró distensión abdominal (36%), abdomen sensible (44%) y tumor palpable (82%). La ecografía abdominal en 44 pacientes reveló tumor sólido 36, sólido/quístico 6 e infiltración de asas en 2. La cirugía realizada fue resección total 28, parcial 5 y biopsia 17. Los diagnósticos fueron tumor de Wilms 19, linfoma tipo Burkitt 14, tumores germinales 7, neuroblastoma 6, hepatoblastoma 2, sarcoma de partes blandas 1, adenocarcinoma suprarrenal 1. En varones hubo mayor frecuencia de linfoma tipo Burkitt y neuroblastoma. Los tumores más frecuentes en < de 5 a os: T. Wilms y neuroblastoma, y en de 5 a os Tu germinales. Se observó evolución prediagnóstico 4 semanas en 50% de las etapas avanzadas y en 12% de las localizadas. Conclusión. Los tumores abdominales se presentan con mayor frecuencia por dolor abdominal y tumoración; el más frecuente fue el tumor de Wilms, existiendo distintas frecuencias según edad y sexo. La ecografía abdominal detectó el tumor en todos, siendo el examen de elección en primera etapa de estudio. La rápida progresión de los tumores malignos en pediatría obliga a considerar la palpación de una masa abdominal como una urgencia pediátrica The objective is to describe the clinical features in children with abdominal tumors. Patients and Method: 50 patients, admitted to Hospital Roberto del Río from december 1998 to april 1999, were reviewed. Results: 52% male; age 1-5 years: 46%. Initial symptoms: pain 40%, abdominal mass 32%. Physical examination: abdominal distension 36%, tenderness 44%, palpable mass 82%. Abdominal ultrasonography (n: 44): solid mass 36, cystic/solid 6, bowel infiltration 2. Surgery: total resection 28, parcial 5, biopsy 17. Diagnosis: Wilms tumor 19, Burkitt like lymphoma 14, germ cell tumor 7, neuroblastoma 6, hepatoblastoma 2, soft tissue sarcoma 1, adrenal carcinoma 1. Main tumors under 5 year-old: Wilms tumor, neuroblastoma; older than 5 year-old: germ cell tumor. Time pre-diagnosis: more than 4 weeks in 50% of advanced stages, and in 12% of localized disease. Conclusion: The principal symptoms were pain and tumor. Wilms tumor was the most frequent, otherwise age and sex give orientation. Ultrasonography detect all cases. Retarding diagnosis 4 weeks was associated wit

Blindness and Fungi Kingdom: a New Approach for Teaching a Biological Theme for Students with Special Visual Needs  [PDF]

Abstract: Teaching students that have visual disabilities differ from others as they need other senses to unveil our extremely visual world. Therefore it is necessary to use specific didactical resources for properly teaching these students. In this work we described a tactical didactical material to teach the Fungi Kingdom topic, an important biological theme that involves diseases and biotechnological contents. The material was constructed with parchment paper and others simple materials that can be produced at school or even home. Its main advantage is the simple preparation and low cost, which allows the construction by anyone about any theme. To identify the effectiveness of this didactical material, we performed an evaluation with blind students, which confirmed its potentiality for using on teaching not only this complex topic but other regarding mycology or other biological themes.
