Only patients undergoing diagnostic thoracentesis were included&#46; This could mean that some PE etiologies are poorly represented&#44; such as heart failure &#40;many patients presenting with characteristic symptoms are diagnosed with pericardial effusion and do not undergo thoracentesis&#41; or pulmonary embolism &#40;effusion is generally insignificant and the patient is usually given anticoagulants while awaiting confirmatory lab results&#41;&#46; In addition&#44; the lack of cardiothoracic surgery services in our hospital could explain the paucity of PE cases associated with these procedures&#46;</p><p id="par0140" class="elsevierStylePara elsevierViewall">In conclusion&#44; cancer&#44; pneumonia and tuberculosis are the causes of most pleural exudates&#44; while heart failure is the main cause of transudates&#46; Pericardial and hepatic hydrothorax conditions are also relatively frequent causes of PE&#46; Pleural tuberculosis predominates in young adults&#44; while in octogenarians the main etiology is heart failure&#46; The bacterial yield from infectious pleural effusion culture is low&#44; except in the case of purulent PF&#46; Likewise&#44; solid medium culture identifies very few cases of tuberculous PE&#46; PF cytology is a simple method for diagnosing malignancies&#44; although it can yield false negatives in at least 40&#37; of cases&#46;</p></span><span id="sec0065" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0125">Funding</span><p id="par0145" class="elsevierStylePara elsevierViewall">No funding was received for this study&#46;</p></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0130">Conflicts of Interest</span><p id="par0150" class="elsevierStylePara elsevierViewall">The authors have no conflicts of interest&#46;</p></span></span>"
