The Impact of the Lisbon Football Derby on the Profile of Emergency Department Admissions

BACKGROUND: Variations in emergency department admissions have been reported to happen as a result of major sports events. The work presented assessed changes in volume and urgency level of visits to a major Emergency Department in Lisbon during and after the city's football derby. MATERIAL AND METHODS: Volume of attendances and patient urgency level, according to the Manchester Triage System, were retrospectively analyzed for the 2008-2011 period. Data regarding 24-hour periods starting 45 minutes before kick-off was collected, along with data from similar periods on the corresponding weekdays in the previous years, to be used as controls. Data samples were organized according to time frame (during and after the match), urgency level, and paired accordingly. RESULTS: A total of 14 relevant periods (7 match and 7 non-match) were analyzed, corresponding to a total of 5861 admissions. During the match time frame, a 20.6% reduction (p = 0.06) in the total number of attendances was found when compared to non-match days. MTS urgency level sub-analysis only showed a statistically significant reduction (26.5%; p = 0.05) in less urgent admissions (triage levels green-blue). Compared to controls, post-match time frames showed a global increase in admissions (5.6%; p = 0.45), significant only when considering less urgent ones (18.9%; p = 0.05). DISCUSSION: A decrease in the total number of emergency department attendances occurred during the matches, followed by a subsequent increase in the following hours. These variations only reached significance among visits triaged green-blue. CONCLUSION: During major sports events an overall decrease in emergency department admissions seems to take place, especially due to a drop in visits associated with less severe conditions.

Lesão Medular Iatrogénica - Realidade no Centro do Alcoitão

Objectivos: A etiologia da lesão medular (LM) é diversa, incluindo, para além da iatrogenia, causas traumáticas,vasculares, neoplásicas, infecciosas, degenerativas, metabólicas e congénitas. Não se conhece a verdadeiracontribuição relativa de cada grupo etiológico na incidência desta patologia no mundo. Numa investigação daliteratura existente foi encontrado apenas um estudo retrospectivo (Bacher et al.) que estudou a incidência da LMiatrogénica num Centro de Reabilitação e caracterizou essa iatrogenia. O objectivo deste trabalho foi o deestudar a incidência e caracterizar a LM iatrogénica numa população de doentes internados no Centro de Medicina de Reabilitação do Alcoitão (CMRA), assim como comparar os resultados com o trabalho atrás referido. Materiais e Métodos: Estudo longitudinal retrospectivo dos doentes com LM admitidos em primeirointernamento no Serviço de Lesões Vértebro-Medulares do CMRA, num período de 5 anos. Procedemos à colheitade elementos demográficos e clínicos do processo destes doentes. A amostra compreendeu 16 doentes. Aincidência de lesão medular iatrogénica foi determinada no período de tempo decorrido entre 1-1-2005 e 31-12-2008 (n=11). Para a caracterização da lesão medular iatrogénica aceitaram-se os doentes internados pela primeiravez entre 1-7-2004 e 30-6-2009 (n=16). Resultados: Obtivemos uma incidência de lesão iatrogénica de 2,7%. A idade média foi de 58 anos, com ligeiropredomínio do sexo feminino. O diagnóstico pré-iatrogenia mais frequente foi a espondilopatia degenerativa(53,3%). Em 50% dos casos, o acto médico iatrogénico foi a cirurgia da coluna vertebral (62,5% da colunalombar), sendo a laminectomia o procedimento mais frequente. Os quadros neuromotores de paraplegia ASIA B(31,2%) e C (37,5%) foram os mais encontrados, com nível neurológico dorsal em 56,2% dos doentes. Em 54,5%dos doentes, o quadro neurológico surgiu no pós-operatório imediato. O estudo de Bacher et al. revelou umaincidência inferior (0,69%) e um quadro neuromotor mais frequente de paraplegia ASIA A. Conclusões: A incidência da lesão medular iatrogénica é um dado epidemiológico mal estudado. A comparaçãoentre os dois estudos revela diferenças importantes de incidência, mas uma caracterização clínica relativamentesobreponível. São necessários mais estudos, nomeadamente multicêntricos, para uma melhor caracterização dalesão medular iatrogénica.

Pneumatose Cólica Tratada com Metronidazol e Oxigenoterapia Hiperbárica: um Caso de Sucesso

A pneumatose intestinal, caracterizada pela presença de gás na parede do cólon, é uma condição incomum com um espectro de apresentação variável. Pode ser idiopática ou secundária a outras doenças. A tomografia computorizada é o método de diagnóstico com maior sensibilidade. Na ausência de sinais e sintomas sugestivos de complicações, como a perfuração e a peritonite, a pneumatose intestinal pode ser tratada de forma conservadora. Apresenta-se o caso de uma mulher de 59 anos com pneumatose cólica secundária a teratoma ovárico benigno. Após a cirurgia, manteve-se sintomática e foi tratada com sucesso com metronidazol e oxigenoterapia hiperbárica.

Use of CPAP to Reduce Arterial Stiffness in Moderate-to-Severe Obstructive Sleep Apnoea, Without Excessive Daytime Sleepiness (STIFFSLEEP): an Observational Cohort Study Protocol

INTRODUCTION: Sleepiness is a cardinal symptom in obstructive sleep apnoea (OSA) but most patients have unspecific symptoms. Arterial stiffness, evaluated by pulse wave velocity (PWV), is related to atherosclerosis and cardiovascular (CV) risk. Arterial stiffness was reported to be higher in patients with OSA, improving after treatment with continuous positive airway pressure (CPAP). This study aims to assess whether the same effect occurs in patients with OSA and without sleepiness. METHODS AND ANALYSIS: This observational study assesses the CV effect of CPAP therapy on a cohort of patients with moderate-to-severe OSA; the effect on the subcohorts of sleepy and non-sleepy patients will be compared. A systematic and consecutive sample of patients advised CPAP therapy will be recruited from a single outpatient sleep clinic (Centro Hospitalar de Lisboa Central-CHLC, Portugal). Eligible patients are male, younger than 65 years, with confirmed moderate-to-severe OSA and apnoea-hypopnea index (AHI) above 15/hour. Other sleep disorders, diabetes or any CV disease other than hypertension are exclusion criteria. Clinical evaluation at baseline includes Epworth Sleepiness Scale (ESS), and sleepiness is defined as ESS above 10. OSA will be confirmed by polygraphic study (cardiorespiratory, level 3). Participants are advised to undertake an assessment of carotid-femoral PWV (cf-PWV) and 24 hours evaluation of ambulatory blood pressure monitoring (ABPM), at baseline and after 4 months of CPAP therapy. Compliance and effectiveness of CPAP will be assessed. The main outcome is the variation of cf-PWV over time.

Symptom Clusters and Survival in Portuguese Patients with Advanced Cancer

This study aimed to identify clusters of symptoms, to determine the patient characteristics associated with identified, and determine their strength of association with survival in patients with advanced cancer (ACPs). Consecutively eligible ACPs not receiving cancer-specific treatment, and referred to a Tertiary Palliative Care Clinic, were enrolled in a prospective cohort study. At first consultation, patients rated 9 symptoms through the Edmonton Symptom Assessment System (0-10 scale) and 10 others using a Likert scale (1-5). Principal component analysis was used in an exploratory factor analysis to identify. Of 318 ACPs, 301 met eligibility criteria with a median (range) age of 69 (37-94) years. Three SCs were identified: neuro-psycho-metabolic (NPM) (tiredness, lack of appetite, lack of well-being, dyspnea, depression, and anxiety); gastrointestinal (nausea, vomiting, constipation, hiccups, and dry mouth) and sleep impairment (insomnia and sleep disturbance). Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter survival was observed for patients with the NPM cluster (58 vs. 23, P < 0.001), as well as for patients with two or more SCs (45 vs. 21, P = 0.005). In a multivariable model for survival at 30-days, age (HR: 0.98; 95% CI: 0.97-0.99; P = 0.008), hospitalization at inclusion (HR: 2.27; 95% CI: 1.47-3.51; P < 0.001), poorer performance status (HR: 1.90, 95% CI: 1.24-2.89; P = 0.003), and NPM (HR: 1.64; 95% CI: 1.17-2.31; P = 0.005), were associated with worse survival. Three clinically meaningful SC in patients with advanced cancer were identifiable. The NPM cluster and the presence of two or more SCs, had prognostic value in relation to survival.
