Método de Stades para a correção da triquíase-entrópio da pálpebra superior : resultados e acompanhamento de 21 casos

Triquíase é a condição na qual os cílios e os cabelos faciais crescem em direção à córnea ou conjuntiva. Os pêlos que surgem de locais normais estão apontados em uma direção anormal. Essa condição pode ser causada por dobras nasais proeminentes, entrópio, blefarospasmo, pele facial redundante e dennóides. A triquíase-entrópio da pálpebra superior associada ao entrópio-ectrópio da pálpebra inferior, frequentemente, ocorre em English Cocker Spaniels idosos. Os sinais oculares são frequentemente epífora, blefarospasmo, conjuntivite, ceratite e ulceração comeana. O tratamento depende da severidade da condição e deve eliminar o contato dos cílios com o globo ocular. Este trabalho apresenta um estudo retrospectivo de 21 pacientes com triquíase difusa bilateral (15 English Cocker Spaniels; 2 Basset hounds; l Bloodhound; l Fila Brasileiro e 2 coes sem raça definida). Empregou-se o procedimento descrito por Stades em todos os casos. No pós-operatório, aplicou-se pomada à base de cloranfenicol (qid) no saco conjuntival e na ferida aberta durante duas semanas. Removeram-se as suturas 10 dias após a cirurgia. Obteve-se êxito na correção do posicionamento da pálpebra superior e observou-se sua justaposição normal em relação à córnea. Ocorreu reepiteliwção completa da ferida um mês após a cirurgia. Não houve sinais de recidiva ou perda da função da pálpebra nos 21 cães avaliados por 36 meses. __________________________________________________________________________________________ ABSTRACTTrichiasis is a condition in which lhe cuia and facial hairs grow toward lhe córnea or the conjunctiva. The hairs arising from normal sites are pointed aí an abnormal direction. This condition may be caused by prominent nasal folds, entropion, blepharospasm, slipped facial mask and dermoids. The upper eyelid trichiasis-entropion with lower eyelid entropionectropion frequentiy occurs in oíder English Cocker Spaniels. The ocular signs often are epiphora, blepharospasm, conjunctivitis, keratitis and comeal ulceratíon. Treatment depenas on the severity ofthe condition and must eliminate the ocular contact by misdirected cuia that irritate the eyeball. This report presents a retrospective study of21 patients with bilateral diffüse trichiasis (15 English Cocker Spaniels; 2 Basset hounds; l Bloodhound; l Fila Brasileiro and 2 mongrel dogs). The procedure described by Stades was employed m ali cases. Postoperatively, topical chioramphenicol oiníment (qid) was appiied in the conjunctival soe and on the open woundfor 2 weeks. Sutures were removed 10 days after surgery. Correction ofpositioning ofthe upper eyelid was successfúl and its apposition to córnea was normal. In most of the cases the reepithelialiwtion was complete one month after surgery. No signs ofrecurrence werefound and there appeared to be no loss of normal fünction of the eyelid in the 21 dogs available for follow-up examination in a maximum period of 36 months

Resultado a longo prazo de tratamento conservador de rabdomiossarcoma vesical infantil: relato de caso/Long term result of conservative treatment of bladder rhabdomyosarcoma in children: case report

Os tumores vesicais ocorrem mais frequentemente entre a quinta e sétima décadas de vida, sendo raros antes dos 40 anos de idade. O rabdomiossarcoma é um tumor embrionário raro originado do tecido muscular esquelético, que, quando localizado no trato geniturinário, se manifesta com hematúria e sintomas urinários obstrutivos. É um tumor que acomete principalmente a faixa etária infantil. Por se tratar de um tumor muito agressivo geralmente necessita de tratamento cirúrgico, com ressecções parciais e até mesmo remoção completa de grande parte do trato geniturinário baixo. Será relatado um caso de rabdomiossarcoma vesical em criança de 5 anos, cujo tratamento sem cirurgia foi curativo e que com acompanhamento a longo prazo não houve recorrência tumoral.   Palavras chaves: Bexiga, rabdomiossarcoma, tratamento conservador     ABSTRACT The bladder tumors occur most often between the fifth and seventh decades of life, being rare before forty. The embryonal rhabdomyosarcoma is a rare tumor originating from the skeletal muscle tissue, which, when located in the genitourinary tract, manifested with haematuria and urinary obstruction. This tumor is more common in the childhood. It’s a very aggressive tumor and usually requires surgical treatment which partial resection and even the complete removal of much of the lower urinary tract. This is a report of one case of bladder rhabdomyosarcoma in a 5 years old child, whose treatment was curative without surgery, and in the long-term following there was no tumor recurrence.   Keywords: Bladder, rhabdomyosarcoma, conservative treatmen

Lectotype designation and redescription of four commonly collected Neotropical species of Strumigenys (Hymenoptera: Formicidae)

In 1887, Mayr described four species of the ant genus Strumigenys collected in the Brazilian state of Santa Catarina: Strumigenys unidentata, Strumigenys subedentata, Strumigenys denticulata, and Strumigenys crassicornis. All of them were described based on a series of one to several specimens, without designation of a holotype, as usual at that time. The same can be said about Strumigenys eggersi, described by Emery in 1890 based on specimens collected in Saint Thomas (U.S. Virgin Islands), without designation of a holotype. In 1961, Brown designated a lectotype for S. unidentata and synonymized it under Strumigenys louisianae. However, the specimens belonging to the type series of the other four species remain as syntypes. Considering that these are four of the most frequently collected species of Strumigenys in the Neotropical region, in this work we provide lectotype designations and complete redescriptions for S. crassicornis, S. denticulata, S. eggersi, and S. subedentata to ensure the taxonomic stability of these names

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
