Comportamento dos músculos estabilizadores da escápula durante rotação de ombro em indivíduos com síndrome do impacto

Devido à grande diversidade de problemas no ombro e da alta incidência da Síndrome do Impacto (SI) torna-se de grande interesse e importância para a reabilitação o comportamento dos músculos da cintura escapular. O objetivo deste estudo foi analisar a ação simultânea dos músculos serrátil anterior e trapézio durante o movimento de rotação do braço na SI. Participaram do estudo 8 indivíduos com SI unilateral, e 8 indivíduos saudáveis, de ambos os sexos, constituindo 3 grupos: Grupo saúdavel (G1-S), Grupo com SI lado acometido (G2-LA) e Grupo com SI lado não acometido (G2-LNA). Este estudo comparou a atividade eletromiográfica dos músculos estabilizadores da escápula durante os movimentos de rotação interna (RI) e rotação externa (RE), por meio de parâmetros que quantificam a co-contração dos pares de músculos TA/TT, TA/TD, TA/SA, TT/TD, TT/SA, TD/SA, normalizados pela CIVM do movimento de RI e RE dos músculos trapézio ascendente (TA), trapézio transverso (TT), trapézio descendente (TD) e serrátil anterior (SA) entre os voluntários com SI unilateral grau I ou II e indivíduos assintomáticos. Os resultados encontrados para a co-contração dos pares de músculos TA/TT, TA/SA, TT/SA e TD/SA do grupo G2 – LA é maior que dos grupos G1 e G2 - LNA no movimento de RE. No movimento de RI não foi observada diferença que fosse decorrente da SI entre os pares musculares. Como os ombros acometidos pela SI apresentaram co-contração dos pares de músculos significativamente maior durante todo o movimento de RE, o exame da cintura escapular na prescrição de tratamento para SI parece ser aspecto importante para ser considerado, tanto na abordagem desses indivíduos quanto no estudo dos fatores etiológicos e de evolução da SI grau I ou II

Efeito protetor após sessões de exercício excêntrico: comparação entre membros superiores e inferiores

The objective of the present study was to compare in which part (lower limb or upper limb) the repeated bout effect has the greatest magnitude. Twelve males individuals with no recent (6 months) experience with resisted training participated in this study. The subjects were randomly divided into two groups (legs and arms) and came to the laboratory 5 times. 1st) adaptation to the dynamometer. 2nd) to perform one bout of eccentric exercise (EE) and provide markers such as isometric peak torque (IPT), delayed onset muscle soreness (DOMS) (both collected before and after the bout) and concentration of the creatine kinase (CK) enzyme in the blood (only before the bout). 3rd) 48 after the first bout the same markers were collected again. After 14 days, the methodologies used in the 2nd and 3rd visits to the laboratory were repeated respectively to determine the repeated bout effect. A significant decrease of IPT and a significant increase of CK and DOMS were found immediately after and 48 hours after the first bout of EE for the arms group. The legs group showed a significant increase in CK (48 hours after the EE) and DOMS (immediately after the EE) resulting from the first bout. In the arms group, the second bout did not cause significant increase in CK or DOMS on any of the situations, however, it provoked a decrease in force production immediately after the EE. The legs group showed a significant increase of DOMS immediately after the second bout of EE, which caused no significant increase in CK. The only marker in which the repeated bout effect happened for both groups was CK. No significant difference was found between the protections for both groups. Taking into account the results, it’s been discussed whether there is a relation between the susceptibility to muscle damage and the repeated bout effect, and also...(Complete abstract click electronic access below)

Correlação entre aneuploidia cromossômica em espermatozóides e taxa de implantação embrionária: subtitulo

Infertility is directly related to chromosomal abnormalities in germ cells. Among them, the aneuploidies are the most frequent chromosomal abnormalities and responsible for embryo implantation failures, miscarriages, fetal losses and newborns with congenital malformations, mental disability and neuropsychomotor developmental delay. Male patients with normal somatic karyotype may present different rates of aneuploidies in sperm, resulting in abnormal embryos. This study aimed to correlate the frequency of chromosomal aneuploidies in spermatozoa with embryo implantation rate in couples undergoing assisted reproductive techniques. The methodology has included chromosomal analysis by GTG banding and molecular cytogenetic study using Fluorescent In Situ Hybridization technique for evaluation of chromosomes 9, X and Y in germ cells of 22 patients referred to the Human Reproduction Service of the Clinical Hospital FMRP-USP. Embryo implantation rates were determined by hormonal evaluation in maternal peripheral blood and ultrasound confirmation. Two patients presented abnormal karyotype, characterized by polymorphism of the heterochromatic region of the long arm of chromosome 9 and a satellite in the short arm of chromosome 22. Both alterations, usually considered variants of normality, have been related to infertility phenotype and miscarriages. Significant differences were detected between couples who presented pregnancy (group 1) and couples with embryo implantation failure (group 2), with higher frequency of aneusomy and diploidy of chromosome 9, as well as total aneuploidy in sperm of group 2 patients. Our results suggest a correlation between aneuploidy and embryo implantation rates, since the infertile group with reproductive failure has showed higher frequency of aneuploidy. Screening for aneuploidies detection in male germ cells should be included in order to decrease embryo implantation failures, miscarriages and fetuses with chromosomal ...

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.

Avaliação da Taxa de Exposição em Exames Radiológicos Realizados em Procedimentos Cirúrgicos - Minimização dos Riscos em Indivíduos Ocupacionalmente Expostos

This paper consists in the evaluation of the exposure rate to ionizing radiation to which professionals working in surgical procedures which require radiological examinations are subjected. Were initially performed real-time readings of exposure rate within four distinct operating rooms during the execution of four surgical procedures that made use of fluoroscopy equipment (including three orthopedic surgeries, one in the shoulder, one in the arm, another for deployment of metal pin in the leg region, and a fourth for vascular procedure); in these surgeries were used ionization chamber detector and an electrometer. In order to check the values achieved, was made a re-evaluation of the distribution of the rate of exposure to radiation, from the surgical procedures, now with thermoluminescent dosimeters (TLDs). For this, thirty TLDs were distributed in the operating rooms, arranged in points of interest as occupation by professionals. The TLDs were prepared for thirty consecutive days, after which they were removed and replaced with new dosimeters not exposed yet. The dosimeters were subjected to reading of the rate of exposure; this procedure was repeated for four months without interruption. The quantification of the results sought primarily to convert the rate of exposure for equivalent dose rate, both in measurements with ionization chamber as in measurements with TLDs, in order to highlight the presence of the biological effect of ionizing radiation for comparisons within scientific context. Then, the results were plotted to establish the relationship between the values of equivalent dose and the distance to the central axis of the x -ray source, confirming the inverse square law for distance. Finally, the values were associated with the maximum limit recommended by the legislation for occupationally exposed individuals. The methodology for the analysis and quantification of the data in this work aims at implementing a work plan that meets ...

Avaliação dos componentes de óleos essenciais 1,8-cineol, β-cariofileno e α-humuleno como possíveis repelentes para Aedes (Stegomyia) aegypti (Diptera: Culicidae)

Aedes aegypti, mosquito da família Culicidae responsável pela transmissão dos vírus da dengue, da febre amarela urbana e da febre chikungunya, apresenta grande proliferação em áreas urbanas das regiões tropicais e subtropicais, além de representar um fator de incômodo por causar alergias devido à inoculação dos componentes salivares durante o processo do repasto sanguíneo. Como forma de evitar os problemas causados por eles, o repelente mais usado e registrado comercialmente desde 1957 é o DEET (N,N-dietil-3-metilbenzamida ou N,N-dietil-meta-toluamida), que apesar de apresentar eficácia comprovada possui determinada toxicidade quando utilizado por crianças e por mulheres grávidas ou lactantes. Atualmente, grande parte dos estudos sobre novas substâncias repelentes envolvem óleos essenciais de plantas, principalmente por serem atóxicos, biodegradáveis, possuírem um preço mais acessível e uma ampla atividade contra diferentes espécies de mosquitos. Os terpenos 1,8-cineol, β-cariofileno e α-humuleno podem ser encontrados em óleos essenciais de uma grande variedade de plantas e apesar de dados da literatura mostrarem uma eficácia dessas substâncias como repelentes para outras espécies de insetos, até o presente momento não existem estudos que relacionam porcentagem de repelência ao longo do tempo para avaliar o potencial de repelência das mesmas para culicídeos.O presente estudo avaliou tais substâncias como possíveis repelentes para A. aegypti, utilizando o DEET como controle positivo. Para avaliar a eficácia do β-cariofileno foi utilizada a BG-cage, uma gaiola desenvolvida especificamente para testes de repelência onde o voluntário expõe um braço sob uma abertura coberta por uma tela onde os mosquitos pousam, mas não picam. Os testes foram repetidos a cada 30 minutos após a aplicação do produto por um tempo máximo de duas horas (seguindo a recomendação de reaplicação do produto comercial ...

Integração ortodontia e dermatologia na busca da excelência na estética bucal

In recent years the number of adult Patients who seek esthetic treatments has increased. Among the patients main concern, lip augmentation has increased, and this procedure has been very well performed and studied by dermatologists and plastic surgeons. Although Orthodontics can achieve good esthetic results through teeth and jaw proper positioning it is a time consuming approach and it discloses some anatomical and biological limitations. Dermatology may be an excellent alternative to enhance orthodontic results through lip augmentation. The aim of this paper is to discuss some dermatology techniques currently available to augment the lips as well as describe a case report highlighting the need for interdisciplinary approach to enhance facial esthetics goals.

Reabilitação oral de paciente com sequela cirúrgica utilizando a técnica da zona neutra: relato de caso clínico

Objective and Case report: The purpose of this paper is to describe the neutral zone technique in a patient with oral deformity on the right labial commissure due to the resection of an oral cancer, enhancing the difficulty resulting from mouth limited opening and the use of tissue conditioner material to determine the neutral zone. Complete denture was obtained through this technique, providing good retention and stability which made functional rehabilitation feasible to patient of his or her masticatory function. Final considerations: The neutral zone technique in complete dentures will determine a specific intraoral area for tooth position and denture base contour where the forces generated by lips, cheeks and tongue are neutralized. The objective of this technique is to provide an alternative approach for patients who presented an historic instability of lower complete denture: atrophic ridge, oral deformities and also with disorder problems. An oral rehabilitation using this technique improves comfort to the patient providing retention and stability of mandibular complete dentures.

A caricatura política na concepção libertária do periódico A Plebe (1947-1949)

This article discusses the meanings of imagistic representations (drawings, cartoons) published in A Plebe (The Plebs), from May 1947 to May 1949, the last period of the Edgard Leuenroth’s headship. Created in 1917, the newspaper, supported by libertarian principles, set up as a public sphere suited for the proletarian world because of discussing the problems that workers were facing in their daily lives. The paper printed whipping criticisms against the country's elites and fought, without respite, the capitalist system – qualified as parasitic, violent and expropriator –, supported by mystifying and equally violent enactments from its religious arm, expressed in the actions of the Catholic Church and whose struggle against was also systematic.
