ABSTRACT
INTRODUÇÃO: A atividade de preensão é uma ação diária essencial em casa e no local de trabalho, onde muitas vezes é necessário levantar e segurar cargas com uma preensão relativamente estática usando contração isométrica. A força e resistência muscular no aspecto proximal das extremidades superiores influenciam na função da mão, e indivíduos com força e resistência reduzidas são mais propensos a desenvolver distúrbios musculoesqueléticos relacionados ao trabalho. Uma boa resistência de preensão pode ser influenciada pela estabilização fornecida pelos músculos do ombro. Este estudo tem como objetivo determinar a extensão da correlação entre resistência de preensão manual e resistência muscular da escápula em jovens assintomáticos. MÉTODO: O tamanho da amostra para este estudo foi n = 62, com base em estudos anteriores. Indivíduos saudáveis, com idade entre 18 e 25 anos, de ambos os sexos, foram incluídos. Uma avaliação objetiva da resistência da preensão foi realizada usando um dinamômetro manual hidráulico, e a resistência escapular foi avaliada usando o teste muscular escapular. RESULTADOS: A análise de dados foi realizada usando o SPSS versão 20. Houve correlações positivas significativas entre as medidas de resistência escapular e a resistência de preensão palmar para ambos os lados (teste de correlação de Pearson, r = 0,612 (p < 0,001) e r = 0,524 (p < 0,001), respectivamente, para resistência de preensão da mão não dominante e dominante). CONSIDERAÇÕES FINAIS: Os achados preliminares deste estudo sustentam que a resistência do músculo escapular exibe uma relação com a resistência da preensão palmar, sugerindo que o treinamento de resistência escapular pode ser um complemento eficaz no processo de reabilitação das funções da extremidade superior.
INTRODUCTION: Gripping activity is an essential daily activity at home and at the workplace, where lifting and holding loads with a relatively static grip using isometric contraction is often required. Muscle strength and endurance in the proximal aspect of the upper extremities influence hand function, and individuals with reduced strength and endurance are more prone to developing work-related musculoskeletal disorders. Good grip endurance might be influenced by the stabilization provided by shoulder muscles. This study aims to determine the correlation between hand grip endurance and scapula muscle endurance among young asymptomatic individuals. METHOD: The sample size for this study is n = 62, based on previous studies. Healthy individuals of both genders, aged between 18 and 25 years, were included. An objective assessment of grip endurance was performed using a hydraulic hand dynamometer, while scapular endurance was evaluated using the scapular muscle test. RESULTS: Data analysis was performed using SPSS version 20. There were significant positive correlations between scapular endurance measures and the hand grip endurance on both sides (Pearson correlation test, r = 0.612 (p < 0.001) and r = 0.524 (p < 0.001), respectively, for non-dominant and dominant hand grip endurance). FINAL CONSIDERATIONS: The preliminary findings of this study support the notion that scapular muscle endurance is related to hand grip endurance, suggesting that scapular endurance training may be an effective adjunct in the rehabilitation process for upper extremity functions.

Background: Medical laboratories are an integral and essential component of the healthcare system. Information about costing and resource management is of paramount importance for providing services at a reasonable price and without quality compromise. Awareness of a scientific method of cost accountingActivity Based Costing (ABC), may contribute significantly to enhance the laboratories capacity to manage its resources efficiently. Objective: This study was done to know the awareness of Activity based costing. Materials & Methods: A preformed validated questionnaire was sent to various laboratory professionals affiliated to private and teaching hospital laboratories. 121 responses were recorded, percentages of which were entered in EXCEL sheets, graphically represented and analysed. Results: Majority of our participants were from medium sized laboratories (40%), working in private sectors, using a combination of automated & semi-automated technologies & not being accredited by regulating bodies. Activity based costing was being implemented in only 14 labs, with more than 70% of respondents not having an adequate knowledge about the same. Inadequate training (44.6%), not being involved in costing (46.3%) and assumed practical difficulties in implementing (9.1%) were some of the reasons cited. Conclusion: Healthcare providers from the laboratory had limited awareness on costing methods like ABC. Efforts to implement and create awareness about the same if made can upscale quality, and sustainable service delivery in lab services at reasonable costs especially in developing country like ours.
ABSTRACT
Hemangiopericytomas of the Central Nervous system present as a distinct clinicopathologic entity, having been categorized as a “mesenchymal-meningothelial tumour”, according to the current WHO classification. Not only is the lesion rare, but it also bears imaging, macro-micro and immunohistochemical similarities to the commoner tumour-meningioma and to the solitary fibrous tumour and has an indolent biological behaviour unlike the other two. We present a case of a 48 year old lady, diagnosed on imaging as meningioma, which turned out to be a dural hemangiopericytoma after complete histological and immunohistochemical work up. Excluding hemangiopericytoma in lesions presenting as intra-cranial tumours is critical, as the tumour is known for recurrence and metastasis, thereby warranting more aggressive treatment by the neurosurgeons, aiding in better patient care. We report this case not only because of its rarity, but also to show the xanthomatous change the tumour showed, not documented in literature so far.
