Background In order to better define the clinical characterization of pulmonary embolism (PE) in the elderly, the clinical and laboratory findings were compared in older (≥65 years old) and younger (<65 years old) patients. Methods and Results The study group comprised 149 patients (58 older and 91 younger) who received a final diagnosis of PE and were retrospectively evaluated. The severity of PE was assessed by calculating the pulmonary vascular obstruction scores (PVOs) scintigraphically: PVOs ≥50% was defined as severe disease. Dyspnea was the most frequent symptom in both groups. Chest pain and hemoptysis were less frequent in older patients (48.3% vs 79.1%, p=0.001; 6.9% vs 20.9%, p=0.021, respectively) whereas syncope occurred more often in the older group (27.6% vs 9.9%, p=0.005). PVOs ≥50% occurred in 55.1% of older and 32.9% of younger patients (odds ratio: 1.67, 95%confidence interval: 1.118-2.507, p=0.013). Conclusions The clinical presentation of PE can be subtle or atypical in elderly patients and hence they may have more severe disease. Therefore, a high clinical suspicion is required in order to prevent delays in diagnostic work-up and initiation of appropriate treatment. (Circ J 2005; 69: 981 - 986)

Introduction: Little is known about whether there is any sex effect on chronic obstructive lung disease (COPD) exacerbations. This study is intended to describe the possible sex-associated differences in exacerbation profile in COPD patients. Methods: A total of 384 COPD patients who were hospitalized due to exacerbation were evaluated retrospectively for their demographics and previous and current exacerbation characteristics. Results: The study was conducted on 109 (28%) female patients and 275 (72%) male patients. The mean age was 68.30±10.46 years. Although females had better forced expiratory volume in 1 second and near-normal forced vital capacity, they had much impaired arterial blood gas levels (partial oxygen pressure [PO₂] was 36.28 mmHg vs 57.93 mmHg; partial carbon dioxide pressure [PCO₂] was 45.97 mmHg vs 42.49 mmHg; P=0.001), indicating severe exacerbation with respiratory failure. More females had two exacerbations and two hospitalizations, while more men had one exacerbation and one hospitalization. Low adherence to treatment and pulmonary embolism were more frequent in females. Females had longer time from the onset of symptoms till the admission and longer hospitalization duration than males. Comorbidities were less in number and different in women (P<0.05). Women were undertreated and using more oral corticosteroids. Conclusion: Current data showed that female COPD patients might be more prone to have severe exacerbations, a higher number of hospitalizations, and prolonged length of stay for hospitalization. They have a different comorbidity profile and might be undertreated for COPD.

Chronic obstructive pulmonary disease (COPD) is an important public health problem that manifests with exacerbations and causes serious mortality and morbidity in both developed and developing countries. COPD exacerbations usually present to emergency departments, where these patients are diagnosed and treated. Therefore, the Emergency Medicine Association of Turkey and the Turkish Thoracic Society jointly wanted to implement a guideline that evaluates the management of COPD exacerbations according to the current literature and provides evidence-based recommendations. In the management of COPD exacerbations, we aim to support the decision-making process of clinicians dealing with these patients in the emergency setting.
