Quantification of multi-oocyte follicles in ovaries of bitches / [Quantificação de folículos multiócitos em ovários de cadelas]

The objective of this study was to quantify the number and frequency of monocyte (MnOF) and multi-oocyte (MtOF) follicles in ovaries of bitches subjected to ovary salpingohysterectomy (OSH). Right and left ovaries of 38 bitches were collected after OSH, prepared, and a histological analysis was carried out. The ovaries were subjected to surface and deep histological cuts; the follicles were classified, and the number of follicles and cumulus oophorus complexes (COC) per follicle were quantified for each histological cut. MnOF and MtOF were found in all ovaries, at different developmental stages; primary follicles were grouped in the ovarian cortex, and follicles at other follicular stages presented a random distribution. MtOF containing two, three, four, or more COC were found in the ovaries of bitches, with a decreasing frequency trend, according to the number of COC in the MtOF. The effect of the age, number of estrus, estrus interval, and number of progenies per delivery was not significant for the number and frequency of MtOF in the ovaries of the bitches, whereas the size, number of pregnancies, use and number of contraceptive applications had some effect on the number and frequency of MtOF in the ovaries of the bitches.(AU)

Objetivou-se, com este estudo, quantificar o número e a frequência de folículos monocitários (MOF) e polioocitários (POF) provenientes de ovários de cadelas submetidas à ovariossalpingo-histerectomia (OSH). Para tanto, coletaram-se os ovários (direito e esquerdo) de 38 cadelas após OSH, com posterior preparação e análise histológica. Cada ovário foi submetido a dois cortes histológicos (superficial e profundo) onde se quantificou o número e a classificação dos folículos, bem como o número de complexos cumulus oophorus (COCs) por folículo em cada corte histológico. Observaram-se MOF e POF em todos os ovários estudados, em diferentes estádios de desenvolvimento, sendo os folículos primários agrupados no córtex ovariano, frente a uma distribuição aleatória dos outros estádios foliculares. FOPs contendo dois, três, quatro ou mais COCs foram observados nos ovários de todas as fêmeas estudadas, e sua frequência tendeu a diminuir de acordo com o número de COC presente no POF. Não se observou influência da idade, do número e do intervalo de estros, assim como do número de filhotes por gestação sobre o número/frequência de FOP nos ovários das cadelas estudadas, enquanto o porte, o número de gestações, o uso e o número de contraceptivo apresentaram algum grau de influência sobre o número/frequência de FOP nos ovários das cadelas estudadas.(AU)

Evaluación objetiva de competencias técnicas en cirugía / [Evaluation of technical skills in surgical training].

INTRODUCTION: technical skills acquisition is considered to be of paramount importance in surgical training. Yet, formal assessment of technical skills is the weakest and less developed area. Currently available resources to evaluate technical skills are largely subjective, and lack of validity and reliability. Direct observation, one of the most frequently used methods, is largely biased by interpersonal subjectivity and personality traits. We propose the creation and use of a new procedure-specific tool for objective assessment of technical skills in surgery to evaluate validity and reliability. MATERIALS AND METHODS: laparoscopic cholecystectomy and Lichstenstein’s inguinal hernia repair were the chosen procedures. Three groups of comparison were defined according to surgical expertise: initial, intermediate, and experts. Surgeries were videorecorded in real time without identification of the patient or the surgeon. Tapes without any posterior edition were assigned to two expert surgeons in a blind and randomized sequence. A newly proposed procedure-specific rating scale was used for evaluation, as well as Reznick’s OSATS global scale. Kruskal-Wallis non-parametric test was used to assess validity. p 0.8 granted reliability. RESULTS: from April 2010 to December 2012 36 laparoscopic cholecystectomies and 31 inguinal hernia repairs were recorded. Significant difference was found among groups of comparison for every item (p<0.05). Crhonbach’s ? was largely over 0,80 for both procedures. There was no significant difference between the assessments of the two raters. There was no significant difference between our newly proposed procedure-specific instrument and Reznick’s OSTATS. DISCUSSION: the objective assessment of technical skills in surgery is feasible and useful. The tool we proposed showed construct validity and reliability. Video recording of surgical procedures grants durability over time to an ephemeral phenomenon. The objectivity is based on the explicit statements and quantification of every step to be evaluated, and the blind randomization and anonymous treatment of the sample. Sharing the same quality criteria between evaluators is of paramount importance to reach satisfactory results. The process of evaluation always implies a shortened view of the reality.

Qualidade microbiológica de queijo-coalho comercializado em Aracaju, SE / Microbial quality of “coalho” cheese commercialized in Aracaju, SE

Determinou-se a ocorrência de Staphylococcus aureus, Salmonella spp. e de microrganismos indicadores de contaminação fecal em queijos-coalho comercializados em 15 pontos de venda do Mercado Central de Aracaju, SE, durante quatro meses. Dezesseis amostras (26,7 por cento) foram positivas para Salmonella spp. e 28 (46,7 por cento) positivas para estafilococos coagulase positiva. Quanto à contaminação por coliformes totais, 56 (93,3 por cento) das amostras apresentaram valores entre 8,0 x10² e 1,23 x10(4)NMP/g, e de 2,72 x10² a 1,12 x10³NMP/g para coliformes termotolerantes. Estes valores não atenderam à legislação brasileira para queijo-coalho e as amostras analizadas podem ser classificadas como impróprios ao consumo humano.

The occurrence of Staphylococcus aureus, Salmonella spp., and microorganisms indicators of fecal contamination in "coalho"cheese commercialized in 15 retail store at the Central Market of Aracaju, SE during four months was determined. Sixteen samples (26.7 percent) were positive for Salmonella spp. and 28 (46.7 percent) for coagulase positive staphylococci. In relation to contamination by total coliforms, 56 samples (93.3 percent) presented values from 8.0 x10² to 1.23 x10(4)NMP/g; and for thermal tolerant coliforms, from 2.72 x10² to 1.12 x10³NMP/g. These values are not acceptable for the Brazilian legislation for "coalho" cheese. This indicates that the analyzed products were inappropriate to the human consumption.
