Cough is probably the most frequent symptom in chest diseases. Hence, a rational and economical diagnostic procedure is essential to prevent unnecessary costs to the health services, i.e. acute bronchitis, a self-limiting disease, which is the most frequent cause for cough should not involve extensive per case costs. History, physical examination, chest X-ray and lung function testing--which constitute both the first and second, i.e. the basic level of a stepwise approach--allows to diagnose causes in most patients with cough. Without evidence of the cause after completing this basic diagnostic procedure patients with acute cough may require blood gases analysis, electrocardiography, echocardiography, lung perfusion study, spiral CT angiography, bronchoscopy or laboratory examinations for diagnosis of pulmonary embolism, aspiration or (seldom) pleuritis sicca. Chronic persistent cough (CPC) is diagnosed if the basic standard approach to chronic cough fails to lead to final diagnosis. Patients will then need further subtle diagnostic management, i.e. bronchial provocation testing, 24 hour pH probe, ENT- or neurological examination, high resolution CT of the thorax and bronchoscopy. We present two algorithms for the rational diagnostic approach to acute (figure 1) and chronic (figure 2) cough. Each algorithm considers spectrum and frequency of causes on the one hand, the positive predictive value, costs and patient discomfort due to the examination on the other. Nonetheless, despite extensive examination up to 20% of patients suffering from CPC the cause remains unclear [11]. Frequently, the capsaicin cough challenge test can reveal an idiopathic upregulation of the cough reflex as the hypothesised underlying condition. Psychogenic cough however, a rare condition in adults should not coincide with hypersensitivity of the cough reflex. Inconsistency and low reproducibility of results of the capsaicin challenge in patients with psychogenic cough preclude his routine clinical use. In conclusion, the very common acute bronchitis and the ACE inhibitor-induced cough do not require any other diagnostic procedure except patient history and physical examination. A simple basic diagnostic approach will usually allow to evaluate acute and chronic cough. In the remaining cases the proposed algorithm should be used for best results and to prevent excessive costs.

Venous thromboembolic disease (deep vein thrombosis and pulmonary embolism) is a frequent and dangerous complication of surgical procedures. Guidelines considering prophylaxis in patients who have a risk of this complication exist in most surgical specialties. In otolaryngology it is a rare illness but a lack of Polish literature and quite few world publications on this subject made the authors check through the literature referring to venous thromboembolic disease in otolaryngology and maxillofacial surgery and indexed in the EMBASE and MEDLINE data bases up till 2003. Incidence of the disease, risk factors with regard to the kind of surgery and prophylaxis methods were presented, all with the aim of creating a kind of a guide useful in clinical practice in ENT.

The prevalence and characteristics of right heart endocarditis in Africa are not well known. The aim of this study was to describe the epidemiological, clinical and laboratory profiles of patients with right-heart infective endocarditis. This was a 10-year retrospective study conducted in 2 cardiology departments in Dakar, Senegal. All patients who met the diagnosis of right heart infective endocarditis according to the Duke's criteria were included. We studied the epidemiological, clinical as well as their laboratory profiles. There were 10 cases of right-heart infective endocarditis representing 3.04% of cases of infective endocarditis. There was a valvulopathy in 3 patients, an atrial septal defect in 1 patient, parturiency in 2 patients and the presence of a pacemaker in one patient. Anaemia was present in 9 patients whilst leukocytosis in 6 patients. The port of entry was found to be oral in three cases, ENT in one case and urogenital in two cases. Apart from one patient with vegetations in the tricuspid and pulmonary valves, the rest had localized vegetation only at the tricuspid valve. However, blood culture was positive in only three patients. There was a favorable outcome after antibiotic treatment in 4 patients with others having complications; three cases of renal impairment, two cases of heart failure and one case of pulmonary embolism. There was one mortality. Right heart infective endocarditis is rare but associated with potentially fatal complications.
