Article: Muscle tissue changes with aging[show abstract] [hide abstract]
ABSTRACT: Sarcopenia is characterized by a progressive generalized decrease of skeletal muscle mass, strength and function with aging. Recently, the genetic determination has been associated with muscle mass and muscle strength in elderly. These two phenotypes of risk are the most commonly recognized and studied for sarcopenia, with heritability ranging from 30 to 85% for muscle strength and 45-90% for muscle mass. It is well known that the development and maintenance of muscle mass in early adulthood reduces the risk of developing sarcopenia and leads to a healthy aging. For that reason it seems important to identify which genetic factors interact with aging and in particular with the musculoskeletal response to exercise in such individuals. This review is designed to summarize the most important and representative studies about the possible association between certain genetic polymorphisms and muscle phenotypes in older populations. Also we will focuses on nutrition and some concerns associated with aging, including the role that exercise can have on reducing the negative effects of this phenomenon. Some results are inconsistent between studies and more replication studies underlying sarcopenia are needed, with larger samples and with different life cycles, particularly in the type and level of physical activity throughout life. In future we believe that further progress in understanding the genetic etiology and the metabolic pathways will provide valuable information on important biological mechanisms underlying the muscle physiology. This will enable better recognition of individuals at higher risk and the ability to more adequately address this debilitating condition.Acta médica portuguesa 01/2013; (in press).

ABSTRACT: Doente do sexo masculino de 86 anos de idade, minei-ro reformado, com história conhecida de doença pulmonar obstrutiva crónica (DPOC), com enfisema pulmonar, car-diopatia isquémica, hipertensão arterial e dislipidémia. Internado por agudização infecciosa da sua DPOC (Figura 1), tendo iniciado antibioterapia empírica. Ao 4º dia de inter-namento, na sequência de acesso de tosse, dor retroester-nal e episódio de hemoptise, repetiu telerradiografia (Figura 2), que revelou imagem cavitada no terço médio do pulmão direito com nível hidroaéreo. Realizou TC torácico (Figura 3), que a par de instalação aguda de imagem cavitada e de estar em continuidade com a cisura interlobar (Figura 4), foi diagnóstica de hemopneu-motórax. O hemopneumotórax espontâneo decorre da ruptura de um pequeno vaso localizado nas aderências entre a pleu-ra visceral e parietal ou de folhetos adjacentes da pleura visceral, como no presente caso. É uma rara complicação do pneumotórax espontâneo (1) e pode resultar de vários me-canismos(2). Tendo em conta as comorbilidades e a estabilidade clínica do doente, optou-se por manter terapêutica conservadora. REFERÊNCIAS 1.

ABSTRACT: Antibiomania, or mania induced by antibiotics, is a rare, but important side effect of clarithromycin and others antibiotics. Although underestimated due to low clinical incidence, this phenomenon is being reported in a growing number of cases of mania associated with administration of antibiotics, in patients without a previous diagnosis of Bipolar Affective Disorder. The importance of Antibiomania in current clinical practice is associated with the increasing introduction and prescription of new antibiotics, and to the need for awareness of the phenomenon as a possible differential diagnosis of secondary mania. There are several theories that may explain Antibiomania, one of the most studied is related to the interaction of antibiotics with neurotransmitters, including the gamma butyric acid (GABA). However, the mechanism is still unknown. The authors present a case of a manic episode triggered by clarithromycin in a patient with no clinical history of disturbance of mood, followed by a brief literature review of the subject, including treatment strategiesActa médica portuguesa 01/2011; 24(5-24 (5)):827-83.

ABSTRACT: Chronic Myeloid Leukemia (CML) is a clonal stem cell disease characterized by the expression of the fusion protein bcr-abl1, which has deregulated tirosine-kinase activity. Tyrosine kinase inhibitors (TKIs), and in particular imatinib, introduced fundamental changes in the treatment of CML, becoming, in most cases, the first-line treatment of choice in the chronic phase of this disease. Compared to other available therapies imatinib results in a marked increase in overall survival, tolerability and quality of life. The introduction of second generation TKI, with increased potency against bcr-abl1, expanded the number of therapeutic options for this disease and offers an alternative for patients resistant or intolerant to imatinib or who have progressed to the accelerated phase under this therapy. In order to achieve optimal outcomes, TKI therapy must be managed rigorously, requiring a careful monitoring of treatment response in pre-established time periods, thus permitting disease evaluation and safe decision of the most adequate option. Despite the definition of the criteria for imatinib treatment response, the therapeutic strategies to adopt according to the responses obtained are less clear. The objective of this paper is to review the criteria for CML diagnosis, treatment and monitoring, with recommendations as to the most adequate therapeutic choice according to the response to TKI therapy. The paper also focuses the current lines of investigation and debate areas that in the short term can significantly change the therapeutic scenario in this disease. These recommendations, supported by published scientific evidence and by the clinical practice of the expert panel involved in their elaboration, may constitute an important instrument for a better understanding and standardisation of the treatment and monitoring of CML in Portugal.Acta médica portuguesa 09/2009; 22:537-544.
