A Recusa Alimentar na Pessoa Idosa

A ingestão de alimentos é uma necessidade humana básica, para a manutenção da vida e da saúde. Uma alimentação equilibrada permite satisfazer as necessidades qualitativas e quantitativas em nutrientes essenciais, de forma a que cada pessoa possa manter a sua actividade física, social e afectiva. Com o envelhecimento dão-se alterações a nível biológico, fisiológico, social e económico que podem alterar os hábitos alimentares do indivíduo idoso. A recusa alimentar pode ser de etiologia multifactorial, motivando frequentemente a recorrer ao serviço de urgência e internamento da pessoa idosa. Esta problemática preocupa-nos, como enfermeiros, pois muitas vezes persiste a dúvida da intervenção mais adequada a tomar. Será a alimentação por sonda nasogástrica a primeira e única opção?

Origem Anómala da Artéria Coronária Esquerda a Partir da Artéria Pulmonar

OBJECTIVE: To assess the frequency and severity of the anomalous origin of the left coronary artery (ALCA) from the pulmonary artery (PA). DESIGN OF THE STUDY: Prospective study of case series between March 1991 and December 1994. SETTING: Referral-based Paediatric Cardiology Department of a Tertiary Care Center. PATIENTS AND METHODS: Five consecutive patients (pts) with anomalous origin of the LCA from the PA; there were three infants aged 4 months and two children one 8 year and one 9 year old. There were three girls and two boys. All pts had clinical and 2D-echo and Doppler investigation prior to cardiac catheterization (CC). Indication for CC was based in the association of symptoms and signs of myocarditis or dilated cardiomyopathy of acute or subacute onset and electrocardiographic (ECG) signs of ischemia in infants. In older patients (pts) diagnosis was suspected mainly from ECG. During CC in all pts, aortograms and when necessary selective coronary angiograms were performed. Surgical correction was performed in all children. In two pts stress exercise ECG and stress Thallium studies before and after surgery were performed. RESULTS: two pts had "adult" an three had "infantile" type of ALCA from the PA. CC was performed and diagnosis was confirmed at surgery in all cases. In one child, correct diagnosis was made by ECO prior to CC and in one case LCA to PA fistula was suspected on Colour-Doppler study. No complications were attributed to CC. Several types of surgery were performed: reimplantation of the ALCA from the PA to the aorta (three pts); tunnel connection of the aorta to the ALCA via the PA (one pt) and left internal mammary to LCA anastomosis (one pt). Two infants died intraoperatively due to extensive myocardial infarction and poor left ventricular function. All the three survivors are asymptomatic after a mean follow up of 34 months. Two oldest pts are currently in New York Heart Association functional class I with normal ECG and improved myocardial perfusion on Thallium scan despite almost total occlusion of LCA at the site of implantation in the aorta as diagnosed on coronary angiogram. CONCLUSIONS: ALCA from PA is associated with major morbidity and mortality. Diagnosis should be suspected in pts with unexplained myocardial ischemia on ECG and even more if it is associated to clinical signs of dilated cardiomyopathy or myocarditis. Careful assessment on ECO and pulsed Doppler and colour flow mapping should make the diagnosis in most cases. Although surgery can be performed based only on ECO diagnosis, we strongly advise for angiography in all cases as in our experience there are false negative diagnosis by ECO. Preoperative Thallium studies can be useful for the selection of the type of surgery as pts with very little viable myocardium will not survive the establishment of a direct systemic to coronary blood flow and may be candidates for heart transplantation.

De Novo Hypertension and Decline of Renal Function in a Young Woman with Systemic Lupus Erythematosus and Antiphospholipid Syndrome

Antiphospholipid syndrome nephropathy and lupus nephritis have similar clinical and laboratory manifestations and achieving the accuracy of diagnosis required for correct treatment frequently necessitates a kidney biopsy. We report the case of a 29-year-old woman referred to the nephrology service for de novo hypertension, decline of renal function and proteinuria. She had had systemic lupus erythematosus and antiphospholipid syndrome since the age of 21 and was taking oral anticoagulation. Two weeks later, after treatment of hypertension and achievement of adequate coagulation parameters, a percutaneous renal biopsy was performed. The biopsy revealed chronic lesions of focal cortical atrophy, arterial fibrous intimal hyperplasia and arterial thromboses, which are typical features of antiphospholipid syndrome nephropathy. We describe the clinical manifestations and histopathology of antiphospholipid syndrome nephropathy and review the literature on renal biopsy in patients receiving anticoagulation.

Angioplastia Primária na Mulher: Realidade Nacional

Objetivos: A mortalidade na mulher após angioplastia primária (ICP-P) é superior à do homem. Contudo, permanece contraditório o papel do sexo poder ser fator de risco independente para mortalidade no contexto de enfarte agudo do miocárdio com supradesnivelamento de ST (EAMST). Com base no Registo Nacional de Cardiologia de Intervenção (RNCI),pretendemos avaliar como é que o género feminino influencia o prognóstico a curto prazo nos doentes com EAMST submetidos a ICP-P a nível nacional. Métodos: De 60 158 doentes incluídos prospetivamente no RNCI de 2002-2012, incluímos na análise 7544 doentes com EAMST tratados por ICP-P, dos quais 25% foram mulheres. Utilizámos modelos de regressão logística e ajustamento por propensity score para avaliar o impacto do sexo na mortalidade hospitalar. Resultados: As mulheres foram mais idosas (68 ± 14 versus 61 ± 13, p < 0,001), mais diabéticas(30 versus 21%, p < 0,001) e hipertensas (69 versus 55%, p < 0,001). Os homens foram revascularizados mais cedo (71 versus 63% nas primeiras 6 horas, p < 0,001). Choque cardiogénico foi mais frequente nas mulheres (7,1 versus 5,7%, p = 0,032). Estas apresentaram um pior prognóstico a curto prazo, com 1,7 x maior risco de morte intra-hospitalar (4,3 versus 2,5%; IC 95% 1,30-2,27; p < 0,001). Utilizando um modelo de regressão ajustado através de um propensity score, o sexo deixa de ser preditor de mortalidade hospitalar (OR 1,00; IC 95% 0,68-1,48; p = 1,00). Conclusões: No RNCI as mulheres com EAMST tratadas com ICP-P apresentaram maior risco cardiovascular, um acesso menos atempado a ICP-P e um pior prognóstico. Contudo, após ajustamento do risco, o género feminino deixa de ser preditor independente de mortalidade hospitalar.

Syndrome In Question

Multiple autoimmune syndrome is a rare condition, described by Humbert and Dupond in 1988. It is defined by the association of at least 3 autoimmune diseases in the same patient. Vitiligo is the most common skin condition in this syndrome. This article presents the case of a 31-year-old male with vitiligo, alopecia areata, Crohn's disease, psoriasis vulgaris and oral lichen planus. The rarity of this case is highlighted by the coexistence of four autoimmune skin diseases in association with Crohn's disease, never described in the literature.

Defeitos da β-Oxidação Mitocondrial: Um Caso Fatal de Deficiência em 3-Hidroxi-Acil-CoA Desidrogenase de Cadeia Longa. (LCHAD)

Descreve-se um caso fatal de deficiência em 3-hidroxi-acil-CoA desidrogenase de cadeia longa (LCHAD) diagnosticado numa criança de 8 meses de idade, segunda filha de um casal jovem, saudável e consanguíneo. Os primeiros sintomas manifestaram-se aos 6,5 meses de idade ao entrar em coma hipoglicémico não cetótico do qual recupera após infusão i.v. de glucose. Detectou-se hepatomegália e posteriormente cardiomegália. A presença de acidúria 3-hidroxi-dicarboxílica foi confirmada após teste de jejum prolongado de 13th e o estudo enzimático efectuado em cultura de fibroblastos de biópsia de pele confirmou o déficit em LCHAD.
