An unexpected cause of a swollen pacemaker pocket: a case report.

Background: A complication originating from the pacemaker pocket after device implantation can most often be explained by a post-operative pocket haematoma, or, less frequently, by a pocket infection. Both conditions need immediate assessment, dedicated treatment, and specialized follow-up. In rare cases, however, a swollen pacemaker pocket has an alternative diagnosis, which is exemplified by the following case. Case summary: A 70-year-old male patient had a-specific symptoms of fatigue, dyspnoea, and coughing for some weeks. He also noted an evident, new swelling of his pacemaker pocket several months after pacemaker implantation, a procedure that was performed in a high-volume center and without any complication. Ultrasound imaging of the pocket suggested the presence of a soft tissue mass with increased vascularity, rather than a fluid collection or a late organized haematoma. Ultrasound-guided biopsy of the mass was obtained for histopathology analysis and revealed a well-differentiated invasive squamous cell carcinoma. Additional PET-CT imaging demonstrated multiple fluorodeoxyglucose-avid hotspots: a voluminous lesion in the left lung hilum, smaller lesions in the liver, some mediastinal lymph nodes, several bone lesions, and a large mass surrounding the pacemaker. The multidisciplinary oncologic specialty team concluded that the patient had an aggressive metastatic lung carcinoma. The patient refused to undergo further treatment and died 1.5 months after diagnosis. Discussion: To the best of our knowledge, we did not find any earlier reports of a squamous cell carcinoma of the lung spreading to a pacemaker pocket. Presentation of a primary tumour or a metastasis in a pacemaker pocket is extremely rare. Ultrasound imaging with ultrasound-guided biopsy is a fast and reliable method to sample the tissue and to obtain a reliable diagnosis.

The role of cardiac rehabilitation in vocational reintegration Belgian working group of cardiovascular prevention and rehabilitation position paper.

Cardiovascular disease is one of the main causes of morbidity and sick leave in Belgium, imposing a great socio-economic burden on the contemporary healthcare system and society. Cardiac rehabilitation is an evidence-based treatment strategy that not only improves the cardiac patients' health state but also holds promise so as to facilitate vocational reintegration in the society. This position paper was developed and endorsed by the Belgian Working Group of Cardiovascular Prevention and Rehabilitation. It provides an overview of the currently available Belgian data with regard to the role of cardiac rehabilitation in return to work after an initial cardiac event. It identifies the relevant barriers and facilitators of vocational integration of cardiac patients and summarises the contemporary Belgian legal and medical framework in this regard. Cardiac rehabilitation remains a primordial component of the post-acute event management of the cardiac patient, facilitating vocational reintegrating and thereby decreasing the pressure on social security. Despite the availability of a relevant legislative framework, there is a need for well-defined algorithms to assess readiness for return to work that can be used in daily clinical practice.

ACE inhibitor-induced angioedema of the small intestine: a case report.

Angiotensin-converting enzyme (ACE) inhibitors are standard medication in treating hypertension, heart failure and diabetic nephropathy. The most common side effects are cough and angioneurotic oedema of the upper airways. A less familiar side effect is the ACE inhibition-induced visceral angioedema. We report the case of a young female patient with recent diagnosis of heart failure (dilated cardiomyopathy due to viral myocarditis), who developed angioedema of the small intestine three weeks after initiating treatment with lisinopril. Symptoms resolved within days once administration of the drug was stopped.

Plasma N-terminal pro-brain natriuretic peptide concentration predicts coronary events in men at work: a report from the BELSTRESS study.

AIMS: Increased levels of neurohormonal markers, including the N-terminal fragment of pro-brain natriuretic peptide (NT-pro-BNP), have been shown to be of prognostic significance in patients with heart failure or coronary heart disease (CHD). The aim of this study was to study the predictive value of NT-pro-BNP for coronary events in a middle-aged population of men at work. METHODS AND RESULTS: A nested case-control study was performed in a large cohort of over 10 000 men at work (aged 35-59) after a median follow-up of 2.66 years. In total, 66 individuals who developed coronary events were matched on a 3-to-1 basis to 198 controls free of coronary events during follow-up. Besides clinical characteristics and conventional cardiac risk factors, NT-pro-BNP (electrochemiluminiscence assay, Roche diagnostics) and serum creatinine levels were determined. In univariable analysis, cases were more frequently current smokers and diabetics, had more frequently a history of CHD, and had higher levels of total cholesterol and systolic blood pressure (SBP), and lower levels of HDL cholesterol. A highly significant difference (P < 0.0001) was noted for NT-pro-BNP levels between cases (median 48.5 pg/mL, interquartile range 26.4-116.6 pg/mL) and controls (30.0 pg/mL, 19.5-47.6 pg/mL). In multivariable conditional logistic regression analysis, NT-pro-BNP remained strongly associated with risk for coronary events [third vs. first tertile, odds ratio (95% CI) 3.24 (1.18-8.85)], independent of body mass index, smoking, diabetes, SBP, total and HDL cholesterol, creatinine, and previous CHD. CONCLUSION: NT-pro-BNP is a strong predictor of coronary events in men at work after a relatively short period, even after adjustment for conventional risk factors.
