Abstract Objective To verify the performance of the Net Promoter Score (NPS) as a tool to assess parental satisfaction in pediatric intensive care units (PICUs). Methods The authors conducted an observational cross-sectional multicenter study in the PICUs of 5 hospitals in Brazil. Eligible participants were all parents or legal guardians of PICU-admitted children, aged 18 years or over. The NPS was administered together with the EMpowerment of PArents in THe Intensive Care (EMPATHIC-30), used as the gold standard, and a sociodemographic questionnaire. For analysis, the results were dichotomized into values greater than or equal to the median of the tests. The associations between the 2 tools were evaluated and the distribution of their results was compared. Results The parents or legal guardians of 78 PICU-admitted children were interviewed. Of the respondents, 85% were women and 62% were in a private hospital. The median NPS was 10 (IQR, 10-10), and the median EMPATHIC-30 score was 5.7 (IQR, 5.4-5.9). Compared with the gold standard, the NPS had a sensitivity of 100% at all cutoff points, except at cutoff 10, where the sensitivity was slightly lower (97.5%). As for specificity, NPS performance was poorer, with values ranging from 0% (NPS ≥ 5) to 47.4% (NPS = 10). Conclusions NPS proved to be a sensitive tool to assess parental satisfaction, but with poor ability to identify dissatisfied users in the sample.

ABSTRACT: Canine atopic dermatitis (cAD) is a worldwide allergic skin disease. The affected dog population can show different clinical patterns according to geographic region, and a lack of studies in Brazil is observed. Therefore, the aim of the present study was to assess the clinical and epidemiological data of cAD in dogs treated in a private clinical practice in Fortaleza, a city located in the Northeast Region of Brazil. cAD was diagnosed in 35% of dogs, being Shih-tzu and Poodle the most affected breeds. Paws and ears were frequently injured sites. Almost 50% of atopic dogs were diagnosed with superficial pyoderma and 36% with cutaneous malasseziosis. Atopic dogs with outdoor habits were less likely to develop cutaneous malassezial infection, and with routine ear, cleaning habits were less likely to develop bacterial otitis externa. In conclusion, canine atopic dermatitis is a prevalent disease in private clinical practice in Fortaleza, and lifestyle habits can be considered a risk factor for cutaneous malasseziosis infection and bacterial otitis externa in atopic dogs.

RESUMO: A dermatite atópica canina (DAC) é uma doença alérgica cutânea de ocorrência mundial. A população canina acometida pode apresentar diferentes padrões clínicos de acordo com a região geográfica e observa-se uma carência de estudos no Brasil. Portanto, o objetivo do presente estudo é avaliar os dados clínicos e epidemiológicos da DAC em cães atendidos em uma clínica privada em Fortaleza, cidade localizada na Região Nordeste do Brasil. A DAC foi diagnosticada em 35% dos cães, sendo Shih-tzu e Poodle as raças mais acometidas. As patas e as orelhas foram locais frequentemente afetados. Quase 50% dos cães atópicos foram diagnosticados com piodermite superficial e 36% com malasseziose cutânea. Cães atópicos com hábitos ao ar livre foram menos propensos a desenvolver malasseziose cutânea e com hábitos rotineiros de limpeza auricular foram menos propensos a desenvolver otite externa bacteriana. Em conclusão, a dermatite atópica canina é uma doença prevalente na prática clínica privada em Fortaleza e os hábitos de vida podem ser considerados como um fator de risco para infecção por malasseziose cutânea e otite externa bacteriana em cães atópicos.

Abstract Anurans are considered one of the most threatened animal groups in the world. Agricultural activities are related to water pollution and contamination, which affects biphasic organisms such as amphibians. Brazilian soybean cultivation covers about 36 million hectares and encompasses many remaining ponds used as breeding sites for amphibians. In this study, we evaluated richness, abundance and composition of the anuran communities in ponds with different levels of association with soybean cultivation. A total of 18 anuran species were recorded with an abundance of 421 collected tadpoles and 1230 adult males on average. Ponds presented in soybean plantations were distinct from those adjacent to plantations regarding water properties and tadpole richness and abundance, as well as composition of tadpoles and adults. Ponds inserted in plantations had communities with lower diversity and abundance. One explanation for these results is likely the detrimental effect of soybean management, which suggests that this decrease is a result of community changes. This serves as an alert about the importance of buffer areas around plantations and the use of adequate techniques for pesticide application.

RESUMO: Uma das formas de se estudar a laminite bovina é sua indução experimental por meio do fornecimento de grande quantidade de carboidrato de alta fermentação. O protocolo mais eficaz até o momento foi o uso de oligofrutose. Objetivou-se avaliar aspectos clínicos e histológicos dos dígitos de bovinos na indução experimental de acidose ruminal e laminite usando oligofrutose. Utilizaram-se seis bezerros mestiços (Bos taurus x Bos indicus) de um ano, divididos em Grupo I (GI) e Grupo II (GII). Os animais em GI e GII receberam oligofrutose por via intrarruminal nas doses de 13 e 17g/kg respectivamente. Os bovinos foram avaliados clinicamente por 28 horas e fragmentos de coroa e muralha abaxial dos dígitos foram colhidos para histologia 30 horas após a indução. Foram identificados sinais de acidose ruminal e metabólica como distensão ruminal com líquido, diarreia e baixo pH ruminal. Os resultados de hemogasometria indicaram baixos pH e nível plasmático de bicarbonato. Os animais não apresentaram claudicação, entretanto, observaram-se apatia e marcha mais lenta, atribuídas à acidose metabólica. Histologicamente foram observadas lesões indicativas de laminite como alterações circulatórias e infiltrado inflamatório na derme, irregularidades e áreas de destacamento da membrana basal e alterações morfológicas de células da epiderme basal. O protocolo induziu, nas primeiras 30 horas, sinais de acidose ruminal e metabólica e lesões histológicas de baixa intensidade nos dígitos. Não foi observada claudicação ou sensibilidade nos dígitos, caracterizando a fase prodrômica da enfermidade.

ABSTRACT: One of the ways to study cattle laminitis is its experimental induction by supplying a large amount of high fermentation carbohydrate. The most effective protocol until now has been the use of oligofructose. The objective of this study was to evaluate clinical and histological aspects of the hoof in experimental induction of ruminal acidosis and laminitis in calves using oligofructose. Six crossbred (Bos taurus x Bos indicus) yearling calves divided into Group I (GI) and Group II (GII) were used. Animals in GI and GII received intraruminal oligofructose in doses of 13 and 17g/kg, respectively. During 28 hours the calves were clinically evaluated and 30 hours after induction, samples were taken from coronary and abaxial wall of the hoof for histologic evaluation. Were noticed signs of ruminal and metabolic acidosis like rumen distension with fluid, diarrhea, ruminal pH reduction and, at blood gas analysis, pH and bicarbonate below reference range. Lameness was not observed however, some animals had a slower gait and apathy, possibly due to metabolic acidosis, though. Histologically, typical lesions of laminitis like circulatory changes and inflammatory infiltrate in the dermis, irregularities and areas of detachment at basement membrane and morphologic changes in cells from basal epidermis were found. The protocol induced, in the first 30 hours, clinical signs of ruminal and metabolic acidosis and low grade histologic lesions in the digits. Lameness and digit pain were not observed, characterizing the prodromic phase of the disease.

Abstract: Twig girdlers have a short adult life and a long larval stage (up to one year in some species). This fact, together with lack of morphological traits to identify the species from the larval stage, poses obstacles for the taxonomic identification and characterization of the many twig girdlers found in the wild. To solve this matter, Random Amplified Polymorphic DNA (RAPD) molecular markers have been applied to identify some insect species and to determine species boundaries. The aim of this study was to identify three species of Oncideres using the RAPD technique. Adults and larvae of O. saga, O. ocularis and O. ulcerosa were collected in Minas Gerais, Brazil. Two RAPD primers were used (OPA-05 and OPB-13), which produced different electrophoretic profiles that were used to construct a UPGMA phenogram. Three groups identified in the analyses accurately separated the three species, based on individuals in two different stages of development (adults and larvae): I: O. saga, II: O. ulcerosa, and III: O. ocularis. Molecular markers, such as RAPD, are valuable tools that help taxonomists in species identification.

An undergraduate organic chemistry experiment for oil extraction and biodiesel production using alternative biomass was developed, whereby oils of avocado, coconut and spent coffee grounds were obtained and submitted to transesterification reaction with CH3OH under NaOH catalysis. Avocado and coffee oils were obtained by typical extraction and coconut oil was obtained through water evaporation of coconut milk in a domestic microwave oven. The commercial oil of licuri (Syagrus coronate), a Brazilian native biomass, was also converted to biodiesel. All four oils and four biodiesels were characterized by 1H-NMR and FTIR, and a comparative study of these spectra reveled that FTIR analyses alone provides enough information to discriminate between oil and biodiesel and confirm transesterification reaction. Besides, the unsaturation degree of all oils was determined by 1H-NMR. A mechanistic proposal concerning the role of NaOH catalysis is presented, excluding the sodium methoxide formation.

O objetivo deste experimento foi isolar a musculatura epaxial da medula espinhal de cães submetidos à laminectomia dorsal modificada (LDM) e averiguar se os músculos influenciaram na formação da fibrose epidural, na compressão medular e no aparecimento dos sinais neurológicos. Para isso, dez cães hígidos foram submetidos à LDM entre as vértebras T13 e L1 e distribuídos aleatoriamente em dois grupos denominados controle (I) onde a medula espinhal permaneceu exposta sem a presença de implante, e tratado (II)onde foi colocado um im-plante a base de alumínio entre a musculatura epaxial adjacente e a medula espinhal exposta pela LDM. As avaliações constaram de exames neurológicos diários até 180 dias de pós-operatório (PO); mielografia, decorridos 15, 30 e 60 dias de PO; e avaliação macroscópica mediante a reintervenção cirúrgica. Não houve diferença durante as avaliações neurológicas. Aos 15 dias de PO, foi verificado na mielografia, que o grau de compressão da linha de contraste foi maior no grupo tratado (P<0,05) quando comparado ao grupo controle, não havendo diferença dos demais tempos estudados. Na avaliação macroscópica, pode-se observar que no Grupo II, a musculatura epaxial adjacente à medula espinhal não estava em contato com a fibrose epidural, diferentemente do grupo controle. O implante pôde ser removido facilmente e apresentava discreto grau de deformidade crânio-dorsal. Pode-se concluir que a musculatura epaxial adjacente é isolada da medula espinhal pelo implante à base de alumínio em cães submetidos à LDM, e esta não influencia na formação da fibrose epidural, compressão medular e no aparecimento dos sinais neurológicos.

The purpose of this study was to isolate the adjacent epaxial musculature from exposed spinal cord by modified dorsal laminectomy in dogs with aluminum implant and to verify whether the muscles contribute to form epidural fibrosis, spinal cord compression, and development of neurological signs. Ten dogs were submitted to modified dorsal laminectomy between T13 and L1 and then distributed along two groups. Dogs in the group 1 remained with the spinal cord exposed without the implant; dogs in the group 2 had an aluminum implant inserted between the epaxial muscles and the exposed spinal cord. Neurological examination was daily performed until 180 days post surgery. Additionally, myelography at 15, 30, and 60 days post surgery and macroscopic evaluation of the implant at six months post surgery were done. There was no difference between groups in the neurological examination. A statistical difference in the degree of spinal compression was observed at day 15 post surgery in the group 2. In this group, the epaxial musculature adjacent to the spinal cord was not in contact with the epidural fibrosis, differently to what was observed in the control group. The implant was removed easily with some degree of deformity. The results showed that the adjacent musculature of the spinal cord submitted to a modified dorsal laminectomy in dogs can be isolated by aluminum implant, without any contact with epidural fibrosis or influence in the development of neurological signs.

Carcinoma triquilemal é uma lesão maligna de baixo grau, pouco freqüente, que se origina de célula do folículo piloso, sendo necessário o diagnóstico diferencial com outros carcinomas de pele. O objetivo do trabalho é relatar um caso de carcinoma triquilemal atendido no ambulatório de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço da Universidade Regional de Blumenau, em um paciente feminino de 86 anos que apresentou lesão em região supraclavicular esquerda, com um ano de evolução e crescimento progressivo, medindo 75x45mm, vegetante, endurecida, avermelhada, friável, com ulceração central, secreção sanguinolenta e dor local. Foi realizada excisão do tumor com margens cirúrgicas livres. Devido ao curso da lesão geralmente não desenvolver metástases, nem recorrência local, optou-se por não realizar terapia adjuvante, apenas acompanhamento periódico da lesão.

Trichilemmal carcinoma is an uncommon low-grade malignant lesion of the outer hair sheath, originating from a hair follicle cell. The differential diagnosis includes other skin carcinomas. This study aims at reporting a case of trichilemmal carcinoma admitted at the Otorhinolaryngology and Head & Neck Surgical Ambulatory, Universidade Regional de Blumenau. The patient was an 86-year-old woman complaining of a reddish lesion on the left supraclavicular region, with one year of evolution and progressive growth, presenting a hardened vegetative mass with central ulceration, blood secretion and local pain. The tumor size was 75x45 mm, which was removed surgically with free margins. Considering that this type of lesion seldom develops metastases or local recurrences, adjuvant therapy was not adopted. The patient has been periodically followed up.

In the absence of the queen, a few workers of F. s. languida developed their ovaries forming nevertheless, only one follicle with a single oocyte which was unable to form yolk spheres. They never showed signals of degeneration or resorption. The corpora allata were homogeneous during all the 5 months of orphanage studied. Its activity might be low but constant, able to maintain the follicle entire, but unable to promote the yolk spheres assembly.
