Lymphangioma of the oral cavity: Case report

The lymphangiomas are hamarthomatous lesions of the limphatic vases. There are benign proliferations that envolve the lymphatic system has a predilection for the head, neck and oral cavity. They represent benign proliferations that involve the lymphatic system, has a predilection for the head, neck and oral cavity. The prognostic for the linfangiomas located in the tongue is good for the most of the patients, although the voluminous lesions can cause obstruction of the aerial ways and consequently the death. The purpose of this study is to report two clinical cases of the lymphangioma located on the tongue, as well as to revise the pertinent literature focusing the clinical aspects and therapeutic possibilities

Handgrip strength

The basic function of the human hand is the manipulation and grasping of various objects in all daily activities, including work activities. This is greatly influenced by strength and manual dexterity. However age, gender and other contexts such as work or leisure activities could influence strength. Handgrip strength, a measure of maximum voluntary force of the hand, has proved to be reliable and valid as an objective parameter to evaluate the functional integrity of the hand as part of the musculoskeletal system. It correlates highly with strength in other muscular groups and is therefore considered as a good indicator of overall muscular strength and functional stress and could be used as a predictor of physical disability. Handgrip strength assessment is simple and reliable and used commonly by several investigators and health professionals, in different contexts (medical, nutritional, rehabilitation, professional settings, engineering, etc.) and with different purposes (research, diagnostic, assessment, etc.). In clinical and rehabilitation settings is of vital importance in the determination of effectiveness of several interventions and for monitoring evolution of diseases. Various ways (methods, techniques and equipments) of collecting information on grip strength have been reported. This chapter will review basic concepts on handgrip function, methodologies of assessment, contexts of application and correlates, such as physical activity, health or nutritional status. Several populations and reference values as also the relationships between handgrip and clinical status, aging, risk of disability and diseases, will be discussed

Morning versus Evening Aerobic Training Effects on Blood Pressure in Treated Hypertension

Introduction The acute blood pressure (BP) decrease is greater after evening than morning exercise, suggesting that evening training (ET) may have a greater hypotensive effect. Objective This study aimed to compare the hypotensive effect of aerobic training performed in the morning versus evening in treated hypertensives. Methods Fifty treated hypertensive men were randomly allocated to three groups: morning training (MT), ET, and control (C). Training groups cycled for 45 min at moderate intensity (progressing from the heart rate of the anaerobic threshold to 10% below the heart rate of the respiratory compensation point), while C stretched for 30 min. Interventions were conducted 3 times per week for 10 wk. Clinic and ambulatory BP and hemodynamic and autonomic mechanisms were evaluated before and after the interventions. Clinic assessments were performed in the morning (7:00-9:00 am) and evening (6:00-8:00 pm). Between-within ANOVA was used (P ≤ 0.05). Results Only ET decreased clinic systolic BP differently from C and MT (morning assessment -5 ± 6 mm Hg and evening assessment -8 ± 7 mm Hg, P < 0.05). Only ET reduced 24 h and asleep diastolic BP differently from C and MT (-3 ± 5 and -3 ± 4 mm Hg, respectively, P < 0.05). Systemic vascular resistance decreased from C only in ET (P = 0.03). Vasomotor sympathetic modulation decreased (P = 0.001) and baroreflex sensitivity (P < 0.02) increased from C in both training groups with greater changes in ET than MT. Conclusions In treated hypertensive men, aerobic training performed in the evening decreased clinic and ambulatory BP due to reductions in systemic vascular resistance and vasomotor sympathetic modulation. Aerobic training conducted at both times of day increases baroreflex sensitivity, but with greater after ET

Prevalência e fatores associados às lesões esportivas em jovens jogadores de futebol

Introdução: O futebol é a modalidade esportiva mais praticada no mundo com milhões de adeptos, incluindo-se crianças e adolescentes. Objetivo: Analisar a ocorrência de lesões esportivas (LEs) e sua relação com fatores associados às lesões em jovens jogadores de futebol. Método: A casuística foi constituída por 102 jogadores (de 12 a 18 anos de idade) procedentes de dois clubes de futebol. Foram registradas informações sobre treinamento e antropometria e os dados de LEs foram obtidos por meio de inquérito de morbidade referida. Considerando-se a taxa de LEs por participante (2,4 LEs/ indivíduo), foram estabelecidos dois grupos: Grupo 1 (G1, n=61), constituído por voluntários com histórico de até dois casos de LEs, e Grupo 2 (G2, n=41), com participantes com pelo menos três casos de LEs. Resultados: Foram registrados 245 casos de LEs em 81 participantes (prevalência de 79,4%). Trauma foi a principal causa de lesões musculoesqueléticas (56,8%); 74,7% envolveram membros inferiores. Composição corporal e exposição foram diretamente associadas à recorrência de LEs. O G2 mostrou maior massa corporal (G1, 56,7±9,5; G2, 61,6±12,5kg) e maior histórico de prática esportiva (G1, 4,8±2,6; G2, 6,2±2,7 anos) do que o G1. Conclusão: A maioria das LEs teve instalação em membros inferiores devido a trauma. Quanto maior o índice de massa corporal e a exposição a treinos, maior a chance de apresentar três ou mais lesões
