Non-Tuberculous Mycobacteria: Seven-Year Experience of a Tertiary Hospital.

INTRODUCTION: Non-tuberculous mycobacteria are ubiquitous organisms. Precise determination of infection numbers is difficult, since reporting them to public health departments is frequently not mandatory; furthermore, isolating a non-tuberculous mycobacteria does not necessarily translate into disease. The aims of this study were to ascertain non-tuberculous mycobacteria data of a tertiary hospital, determine the incidence and approach to colonization versus disease, and the incidence of predisposing comorbidities. MATERIAL AND METHODS: Retrospective study in a tertiary hospital, involving patients with positive cultural exam for non-tuberculous mycobacteria in any biological sample, from 2010 to 2017. RESULTS: A total of 125 non-tuberculous mycobacteria isolates was identified, corresponding to 96 patients. Of these, 57.4% were male (n = 54); median age was 65 years (interquartile range = [50 - 82]). From these, 60.7% (n = 57) had some degree of immunosuppression, most frequently due to malignant tumour (49.0%) or HIV infection (39.2%). It was found that 29 patients (31.0%) had structural respiratory tract changes. Colonization was defined in 65.6% of patients (n = 63). While 71.0% of non-tuberculous mycobacteria infections were pulmonary, the remaining 29.0% presented as disseminated. According to available clinical records, 60.6% (n = 20) of the presumably infected patients fulfilled American Thoracic Society diagnostic criteria for non-tuberculous mycobacteria disease. DISCUSSION: Several cases of non-tuberculous mycobacteria infection in this study presented as life-threatening, multi-systemic disease, highlighting the importance of accurate diagnosis and timely treatment. Other cases of presumed infection might instead have corresponded to colonization, possibly resulting in futile therapy. CONCLUSION: While there are diagnostic criteria for treatment of non-tuberculous mycobacteria infections, no such guidelines exist to assess colonization. One of the most challenging aspects remains the correct differentiation between colonization and early-stage infection.

Introdução: Micobactérias não-tuberculosas são organismos ubiquitários. A determinação precisa de incidência e prevalência de infecções por estes agentes é difícil, uma vez que na maioria dos países não são de declaração obrigatória e o isolamento de micobactérias não-tuberculosas não traduz obrigatoriamente a presença de doença. Os objectivos do estudo foram a avaliação dos dados epidemiológicos e abordagem de micobactérias não-tuberculosas num hospital terciário, determinar a incidência de colonização versus infecção, e a presença de comorbilidades. Material e Métodos: Estudo retrospetivo num hospital terciário envolvendo doentes com exame cultural positivo para micobactérias não-tuberculosas em qualquer amostra biológica, de 2010 a 2017. Resultados: Foram isoladas 125 micobactérias não-tuberculosas, correspondendo a 96 doentes. Destes, 57,4% era do sexo masculino (n = 54); a mediana de idade era 65 anos [50 - 82], 60,7% encontrava-se imunossuprimidos, mais frequente tumor maligno (49,0%) ou infeção por vírus da imunodeficiência humana (39,2%). Vinte e nove doentes (31,0%) apresentavam alterações estruturais crónicas da árvore traqueo-brônquica. Colonização assintomática foi identificada em 65,6% dos doentes (n = 63). Do total da amostra, 71,0% das infeções por micobactérias não-tuberculosas era pulmonar, e os restantes 29,0% disseminada. De acordo com os registos clínicos disponíveis, 60,6% (n = 20) das infeções presumidas preenchia critérios de diagnóstico da American Thoracic Society. Discussão: Foram identificados vários casos de infeção multi-sistémica grave, sublinhando a importância do diagnóstico e tratamento adequados e atempados. Paralelamente, foram também descritos casos de infeção presumida que poderão ter correspondido apenas a colonizações assintomáticas. Conclusão: Enquanto se encontram publicados critérios de diagnóstico de infeção por micobactérias não-tuberculosas, tal não acontece até à data para avaliar colonizações. Assim, um dos aspectos mais desafiantes da gestão destes casos é a correcta diferenciação entre colonização assintomática e infeção em fase inicial.

Do-not-resuscitate and treatment limitation decisions - Six years of experience from a Portuguese General Intensive Care Unit.

OBJECTIVE: Treatment limitation, as well as do-not-resuscitate (DNR) directives, are difficult but important to improve patients' quality of life and minimize dysthanasia. We aimed to study the approach to withholding, withdrawal, and DNR decisions, patients' characteristics, and process documentation in a general Intensive Care Unit (ICU) in Portugal. METHODS: A retrospective analysis of data regarding the limitation of treatment decisions collected from previously-designed forms and complemented by medical record consultation. RESULTS: A total of 1602 patients were admitted to the ICU between 2011 and 2016. DNR decisions were documented in 127 cases (7.9%). Patients with treatment limitations were older and had higher Simplified Acute Physiology Score II. The most frequent diagnosis preceding these decisions was sepsis (52.0%, n = 66); the most common main reason for limiting treatment was a poor prognosis of acute illness. Of the patients to whom a DNR was implemented, 117 (92.1%) died in the ICU (40.1% of the total number of ICU deaths), and hospital mortality was 100%. Participants in these decisions, as well as types of treatment withdrawn and their respective timings, were not registered in medical records. CONCLUSION: Treatment limitation and DNR decisions were relatively common, in line with other Southern European studies, but behind Northern European and North American centers. Patients with these limitations were older and more severely ill than patients without such decisions. Documentation of these processes should be clear and detailed, either in specific forms or computerized clinical records; there is room for improvement in this area.

Palliative approach in acute neurological events: a five-year study.

INTRODUCTION: Acute neurological illness often results in severe disability. Five-year life expectancy is around 40%; half the survivors become completely dependent on outside help. OBJECTIVE: Evaluate the symptoms of patients admitted to a Hospital ward with a diagnosis of stroke, subarachnoid hemorrhage or subdural hematoma, and analyze the role of an In-Hospital Palliative Care Support Team. MATERIAL AND METHODS: Retrospective, observational study with a sample consisting of all patients admitted with acute neurological illness and with a guidance request made to the In-Hospital Palliative Care Support Team of a tertiary Hospital, over 5 years (2012-2016). RESULTS: A total of 66 patients were evaluated, with an age median of 83 years old. Amongst them, there were 41 ischaemic strokes, 12 intracranial bleedings, 12 subdural hematomas, and 5 subarachnoid hemorrhages. The median of delay between admission and guidance request was 14 days. On the first evaluation by the team, the GCS score median was 6/15 and the Palliative Performance Scale (PPS) median 10%. Dysphagia (96.8%) and bronchorrhea (48.4%) were the most prevalent symptoms. A total of 56 patients had a feeding tube (84.8%), 33 had vital sign monitoring (50.0%), 24 were hypocoagulated (36.3%), 25 lacked opioid or anti-muscarinic therapy for symptom control (37,9%); 6 patients retained orotracheal intubation, which was removed. In-hospital mortality was 72.7% (n=48). DISCUSSION AND CONCLUSION: Patients were severely debilitated, in many cases futile interventions persisted, yet several were under-medicated for symptom control. The delay between admission and collaboration request was high. Due to the high morbidity associated with acute neurological illness, palliative care should always be timely provided.

Large Morgagni Hernia in an Adult Patient.

A 70-year-old woman presented to the emergency department with symptoms of a lower respiratory infection. A chest x-ray showed enlargement of the mediastinal space. The patient was admitted with a respiratory tract infection and started on antibiotic treatment. A computed tomography (CT) scan of the thorax revealed a large diaphragmatic hernia with stomach, large intestine and caudal pancreas lodged in the thoracic cavity. After the antibiotic treatment, the patient became asymptomatic and surgery repair was declined. Morgagni hernia is an uncommon type of congenital diaphragmatic hernia, which may be asymptomatic until late in life or may be present acutely with life threatening conditions. LEARNING POINTS: Morgagni hernia is the most rare form of congenital hernia, representing 2 to 3% of all cases.Chronic respiratory symptoms or gastrointestinal disturbances can be the only manifestation.Most asymptomatic cases in adults are found after doing chest x-ray for unrelated problems.

Yellow Nail Syndrome: Report of Two Cases and a Brief Review of the Current Literature.

Yellow Nail Syndrome (YNS) is a rare, and probably misdiagnosed, condition. It must be considered in middle-aged patients with unexplained chronic respiratory manifestations, lymphedema and nail abnormalities. We present two cases of undiagnosed YNS until the current admissions, despite several years of investigation. The authors wish to draw attention to this syndrome, of which diagnosis is clinical and of exclusion. LEARNING POINTS: Yellow nail syndrome is characterized by abnormal nails, lymphedema and respiratory manifestation.Diagnosis is clinical and should raise the suspicion of underlying medical conditions. The treatment is symptomatic.

RESUMO OBJETIVO Decisões de limitação terapêutica (DLT) e de não reanimação (DNR) são difíceis, mas importantes, visando melhorar a qualidade de vida dos doentes e minimizar distanásia. O objetivo deste estudo foi avaliar a abordagem das DNR e DLT, as características dos doentes e a documentação dessas decisões numa Unidade de Cuidados Intensivos Polivalente (Ucip) em Portugal. MÉTODOS Análise retrospectiva dos dados referentes a DLT e DNR, recolhidos a partir de formulários previamente elaborados e complementados por consulta de processo clínico. RESULTADOS Um total de 1.602 doentes foi internado na Ucip entre 2011 e 2016. DNR foi documentada em 127 casos (7,9%). Doentes com DLT eram mais velhos e tinham um Simplified Acute Physiology Score II mais elevado. O diagnóstico mais frequente que precedeu essas decisões foi sepse (52,0%, n=66); A razão mais comum para limitar o tratamento foi mau prognóstico da doença aguda. Dos doentes nos quais a DNR foi implementada, 117 (92,1%) morreram na Ucip (40,1% do total de óbitos na Ucip) e a mortalidade hospitalar foi de 100%. Os intervenientes nessas decisões, bem como os tipos de tratamento retirados, não foram rotineiramente registrados. CONCLUSÃO As DLT e DNR foram relativamente comuns, em consonância com outros estudos do sul da Europa, mas atrás dos centros do norte da Europa e da América do Norte. Os doentes com essas limitações eram mais velhos e mais gravemente doentes. A documentação dessas decisões deve ser clara e detalhada, seja em formulários específicos, seja em registros clínicos informatizados. Há espaço para melhorias nessa área.

RESUMO INTRODUÇÃO Eventos neurológicos agudos resultam frequentemente em incapacidade grave que impede o doente de participar ativamente nas decisões do seu próprio tratamento. A sobrevida a cinco anos ronda os 40%; metade dos sobreviventes fica dependente de terceiros. Objetivo Avaliar a sintomatologia de doentes internados com acidente vascular cerebral (AVC), hemorragia subarcnoideia (HSA) ou subdural (HSD) e analisar a intervenção de uma Equipe Intra-Hospitalar de Suporte em Cuidados Paliativos (EIHSCP). MATERIAL E MÉTODOS Estudo retrospetivo observacional dos doentes com diagnóstico principal de evento neurológico agudo com pedido de colaboração à EIHSCP, num hospital terciário, durante cinco anos (2012-2016). RESULTADOS Avaliados 66 doentes, com média de idade de 83 anos. Destacam-se 41 AVC isquêmicos, 12 hemorrágicos, 12 HSD e 5 HSA. A média da demora entre internamento e pedido de colaboração à EIHSCP foi de 14 dias. Na primeira observação, a média na escala de coma de Glasgow foi de 6/15 e na Palliative Performance Scale (PPS) foi de 10%. Disfagia (96,8%) e broncorreia (48,4%) foram os sintomas mais frequentes. A maioria dos doentes (56/66) mantinha sonda nasogástrica (84,8%); 33 encontravam-se em monitorização cardiorrespiratória (50,0%); 24 estavam sob hipocoagulação (36,3%); 25 necessitavam de opioide e antimuscarínico que não estavam prescritos (37,9%); seis tinham tubo orotraqueal, que foi retirado. A mortalidade intra-hospitalar foi de 72,7% (n=48). DISCUSSÃO E CONCLUSÃO Destaca-se o estado debilitado dos doentes; em muitos casos, intervenções fúteis persistiam, mas várias foram submedicadas para o controle dos sintomas. Verificou-se um tempo de espera elevado até o pedido de colaboração. Pela elevada morbilidade associada a esses eventos, cuidados paliativos diferenciados deveriam ser oferecidos no tempo adequado.
