Planear a Alta do Doente Neurocirúrgico em Situação Crónica: o Retrato de uma Realidade

Cuidar de um doente crónico do foro neurocirúrgico é uma arte que requer da parte do enfermeiro o desenvolvimento de competências específicas, dado que é um processo longo e complexo. Esta complexidade, está relacionada não só com a dependência que o doente apresenta, mas também com a forte carga emocional que se reflecte na família/prestador de cuidados. A elaboração de um procedimento orientador de preparação para a alta emergiu como uma necessidade sentida pela equipa de enfermagem. Este procedimento sugere as etapas do ensino a efectuar, permitindo sinalizar o caminho percorrido, inventariar as actividades mais difíceis para o cuidador informal e ser ainda um instrumento de continuidade, para a equipa hospitalar e de comunidade. Esperamos que o desenvolvimento de competências na família, possa diminuir a ansiedade e o stress promovendo estratégias de coping no cuidado ao doente em estado vegetativo.

Routine Transthoracic Echocardiography in a General Intensive Care Unit: an 18 Month Survey in 704 Patients

The authors analyzed 704 transthoracic echocardiographic (TTE) examinations, performed routinely to all admitted patients to a general 16-bed Intensive Care Unit (ICU) during an 18-month period. Data acquisition and prevalence of abnormalities of cardiac structures and function were assessed, as well as the new, previously unknown severe diagnoses. A TTE was performed within the first 24 h of admission on 704 consecutive patients, with a mean age of 61.5+/-17.5 years, ICU stay of 10.6+/-17.1 days, APACHE II 22.6+/-8.9, and SAPS II 52.7+/-20.4. In four patients, TTE could not be performed. Left ventricular (LV) dimensions were quantified in 689 (97.8%) patients, and LV function in 670 (95.2%) patients. Cardiac output (CO) was determined in 610 (86.7%), and mitral E/A in 399 (85.9% of patients in sinus rhythm). Echocardiographic abnormalities were detected in 234 (33%) patients, the most common being left atrial (LA) enlargement (n=163), and LV dysfunction (n=132). Patients with these alterations were older (66+/-16.5 vs 58.1+/-17.4, p<0.001), presented a higher APACHE II score (24.4+/-8.7 vs 21.1+/-8.9, p<0.001), and had a higher mortality rate (40.1% vs 25.4%, p<0.001). Severe, previously unknown echocardiographic diagnoses were detected in 53 (7.5%) patients; the most frequent condition was severe LV dysfunction. Through a multivariate logistic regression analysis, it was determined that mortality was affected by tricuspid regurgitation (p=0.016, CI 1.007-1.016) and ICU stay (p<0.001, CI 1-1.019). We conclude that TTE can detect most cardiac structures in a general ICU. One-third of the patients studied presented cardiac structural or functional alterations and 7.5% severe previously unknown diagnoses.

Prognostic Factors in Adult Patients with Idiopathic IgA Nephropathy

Introduction. IgA nephropathy is the dominant primary glomerular disease found throughout the majority of the world’s developed countries. Accurately identifying patients who are at risk of progressive disease is challenging. We aimed to characterise clinical and histological features that predict poor prognosis in adults. Patients and Methods. We performed a single-centre retrospective observational study of biopsy-proven IgA nephropathy. The primary outcome was renal survival and death from any cause, and the secondary outcome was proteinuria remission. Results. Data from 49 cases were available for analysis with a median follow-up of 4 years. There were no deaths. Univariable analyses identified acute renal failure, low estimated glomerular filtration rate for ≥3 months (low eGFR), arterial hypertension, baseline proteinuria, glomerular sclerosis >50% and interstitial fibrosis >50% as poor prognostic markers. Low eGFR persisted significant by multivariable model that used only clinical parameters. Multivariable models with histopathologic parameters observed that tubular atrophy/interstitial fibrosis >50% was independently associated with the primary outcome. Proteinuria remission throughout follow-up had no prognostic value in our revision. Conclusions. Two independent predictors of poor renal survival at time of biopsy were found: low eGFR and tubular atrophy/interstitial fibrosis >50%.

Saúde Sexual e Reprodutiva das Adolescentes - a Nossa Realidade

Overview and Aims: Several behavioral and biological factors can make adolescents particularly vulnerable to unwanted pregnancies and sexually transmitted diseases. The aim of this study was to evaluate sexual behavior and contraceptive use patterns of a population of adolescents. Study Design: Retrospective study. Population: 163 female adolescents attending an Adolescence Unit for the first time, during 2010. Methods: Analysis of clinical charts and assessment of demographic data, smoking and drinking habits, drug use, gynecologic and obstetric history, sexual behavior and contraceptive use. Results: The mean age was 16.04 years (±1.32). 71.7% were students (of these, 70% had failed one or more years and were behind in their studies), 2.5% were working and 23.9% were neither studying or working. 95.1% had already had sexual intercourse and the mean age of first coitus was 14.53 years (±1.24). There was a history of at least one previous pregnancy in 77.3% of the cases. Before the first appointment at the AU, the contraceptive methods used were: the pill (33.2%, but 41.3% of these reported inconsistent use), and the condom (23.9%, with inconsistent use in 28.3% of these cases). 19.6% did not use any contraceptive method.. After counseling at the AU, 54% of the teenagers chose the contraceptive implant and 35% preferred the pill. Adolescents who had already been pregnant preferred a long acting method (namely, the contraceptive implant)in 61.9% of cases; those who had never been pregnant decided to use an oral contraceptive in 67.6% of cases (p<0.001). Conclusions: After counseling the number of teenagers using contraception increased. In this population there were a high number of adolescents with a previous pregnancy. This factor seems to have influenced the choice of the contraceptive method, with most of these adolescents choosing a long-acting method.

Neurofibromatose de Von Recklinghausen

A neurofibromatose é uma doença multissistémica na qual as possíveis múltiplas manifestações clínicas podem ter importantes implicações diagnósticas e prognósticas: se coexiste hipertensão arterial, vários mecanismos patogénicos justificam que se considere a possibilidade da etiologia secundária. Neste trabalho, revemos mecanismos patogénicos e manifestações clínicas, e apontamos estratégias diagnósticas para anomalias e doenças, que embora presentes, podem estar ocultas.
