MS-222 and Propofol Sedation during and after the Simulated Transport of Nile tilapia (Oreochromis niloticus).

The use of anesthetics has been suggested as a strategy to hamper live fish transport-induced stress. Still, there is insufficient data available on the use of alternative anesthetics to MS-222. This study investigated the use of propofol to mitigate stress in Nile tilapia (Oreochromis niloticus, 143.8 ± 20.9 g and 20.4 ± 0.9 cm) during a 6 h simulated transport. Individuals (n = 7) were divided into three groups: control, 40 mg L-1 MS-222, and 0.8 mg L-1 propofol. A naïve group non-transported was also considered. During the 6 h transport and 24 h after, the response to external stimuli, opercular movements, water quality parameters, behavior, blood hematology and other physiological values, the histopathology of the gills, the quality of the fillet, and oxidative-stress changes in gills, muscle, brain, and liver were evaluated. Propofol increased swimming activity of fish but decreased opercular movements and responses to external stimuli, indicating oscillations of the sedation depth. Water pH and glucose levels increased, while hematocrit (HCT) and lactate decreased in propofol groups at 6 h. At this time-point, MS-222 also induced a decrease in the HCT and lactate levels while increasing cortisol levels. Despite these effects, the stress-related behaviors lessened with anesthetics compared to the control group. After the recovery period, physiological responses normalized in animals from both anesthetic groups, but the control still had high cortisol levels. Overall, propofol is a good alternative for the transportation of this species, showing efficient sedation without compromising health or fillet quality. However, further pharmacodynamics and pharmacokinetics knowledge is required to support its use in aquaculture settings.

Prevalence of depression and anxiety disorders in hospitalized patients at the dermatology clinical ward of a university hospital.

BACKGROUND: The objective of this study was to estimate the prevalence of depression and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in São Paulo, Brazil. OBJECTIVE: To assess the prevalence of mood and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in São Paulo. METHOD: A total of 75 patients, men and women, aged between 18 and 76 years, took part in the research. The study employed a descriptive, cross sectional and correlational method. The data was collected by means of a social demographic questionnaire and the PRIME-MD. RESULTS: It was found that 45.3 percent of the subjects presented with depressive symptoms, and 52 percent presented with symptoms of anxiety and that this survey showed moderate and high significant correlations (p<0,01; r= 0,616) for depression and anxiety. CONCLUSION: These facts could evidence the relationship between physical and psyche, just as the literature presents.

FUNDAMENTOS: O presente estudo teve como objetivo verificar a freqüência de depressão e ansiedade em pacientes internados na Divisão da Clínica de Dermatologia de um hospital universitário de São Paulo. OBJETIVO: Avaliar a prevalência de depressão e ansiedade em pacientes hospitalizados na enfermaria da clínica de dermatologia de um hospital universitário em São Paulo. MÉTODO: Participaram da pesquisa 75 sujeitos, homens e mulheres, entre 18 e 76 anos. O delineamento do estudo foi transversal e descritivo. Os instrumentos utilizados foram Entrevista Sócio Demográfica e PRIME-MD. RESULTADOS: Identificou-se a presença de depressão em 45,3% e de ansiedade em 52% dos pacientes avaliados. CONCLUSÃO: Verificou-se correlação moderada e altamente significativa (p<0,01; r =0,616) para os índices de depressão e ansiedade, que pode evidenciar a relação entre adoecimento físico e psíquico muito encontrada na literatura.

Volkmann ischemic contracture in a newborn.

Congenital Volkmann ischemic contracture is a very rare condition in which a neonate presents skin, muscular and nerve lesions due to increased intracompartment pressure and subsequent ischemia, probably due to extrinsic intrauterine compression. In this age group, there are only about 50 reported cases and a specific cause is unknown. The authors describe the case of a newborn who presented with bullous and ulcerated skin lesions and nerve palsy of his forearm at birth, evolving to subcutaneous and muscular necrosis and contracture. Two surgeries were performed and the baby began a daily physiotherapy program that resulted in aesthetical improvement and recovery of his hand and forearm mobility. Early recognition of this rare entity and subsequent emergency fasciotomy are the best ways to improve prognosis.

Estudo introdutório sobre transtorno de humor e a autoestima de mulheres com doenças dermatológicas / Introductory study about humor disorders and self-esteem on women with skin diseases

A pele é o primeiro órgão de contato com o exterior e o meio estruturante na formação da autoimagem, podendo, as afecções, comprometer a forma como o sujeito se vê e se relaciona com os outros, desencadeando ou intensificando perturbações no estado de humor. Assim, este trabalho teve como objetivo estudar a presença de Transtorno de Humor (ansiedade e depressão) em uma amostra de 47 mulheres internadas em uma Enfermaria de Dermatologia de um Hospital Universitário, bem como avaliar o impacto das doenças dermatológicas na autoestima e autopercepção. Foram utilizados três instrumentos: Mini Mental, Questionário Sócio-demográfico e PRIME-MD. Foi observada a frequência 53,2% de depressão e 59,6% de ansiedade e que as desordens na pele influenciam na saúde mental e física das pacientes, estando presentes sentimentos de inadequação e atitudes de isolamento e apatia(AU)

The skin is the first contact organ with the external ambient and the structuring element on self-image construction and can compromise the way the person deals with herself and the others, causing or intensifying humor disturbances. Therefore, this article studies the presence of Humor Disorders (anxiety and depression) on 47 women interned on Dermatologic Nursery of a University Hospital, evaluating the impact of skin diseases on their self-esteem and self-perception. Three instruments were used: Mini Mental, Social Demographic Questionnaire and PRIME-MD. It was possible to observe the frequency of 53,2% Depression and 59,6% Anxiety and that skin diseases have influence on mental and physical health of the patients, wich have feelings of discomfort and isolation attitudes(AU)

G2P[4] the most prevalent rotavirus genotype in 2007 winter season in an European non-vaccinated population.

BACKGROUND: Recently, a high prevalence of G2P[4] rotavirus (RV) infection was reported from Brazil, and linked with the universal RV vaccination programme that used the G1P[8] live oral RV vaccine. OBJECTIVE: To determine the genotypes of RV co-circulating in a non-vaccinated population, in northern Portugal in the winter season of 2007. STUDY DESIGN: Prospective multicenter study of the genotypes circulating in the northwest region of Portugal during January to March 2007. Children with acute gastroenteritis, who attended the Pediatric Emergency Services of five Hospitals, were included in the study. The parents of the children completed a clinical and epidemiological data questionnaire and stool samples were collected. Stool samples positive in a RV enzyme immunoassay (EIA) were genotyped by reverse transcriptase-polymerase chain reaction. RESULTS: Stool samples were collected from 424 children. Two hundred and thirty-four (55.2%) stool samples were RV-positive. G2P[4] was the predominant RV type (68.6%), followed by G9P[8] (14.0%). CONCLUSIONS: Because our population was naïve for RV vaccine, the G2P[4] predominance cannot be explained by vaccination. Rather, this high prevalence of G2P[4] may be within the normal fluctuation of RV genotypes. RV strain surveillance programmes are important for informing RV vaccination programmes.
