The present paper describes eight patients (two teenagers and six adults) who had chronic symptoms (haemoptysis, cough, recurrent pneumonia) caused by foreign body (FB) inhalation which went undetected for 3 months to 25 yr. None of the patients had the usual predisposing conditions like mental retardation, seizures or brain tumour. The diagnosis of FB was made by radiography in one patient only. Computerized tomography visualized one FB (a beef bone), and bronchoscopy identified FB in another two patients. The remaining four cases were diagnosed at thoracotomy. Removal of FB was curative in three of five cases who required surgical resection for irreversible bronchiectatic changes. The severity of pulmonary changes correlated with duration of symptoms. It is concluded that chronic, unexplained respiratory symptoms should warrant further investigation to exclude FB despite negative history and normal chest radiography. Finding of granulation tissue or cicatricial stenosis of the bronchus could be the only clue to the presence of a FB. Early diagnosis would avoid irreversible parenchymal changes which necessitate lung resection.

To our knowledge, no study has examined the persistence of sleep disordered breathing in acute coronary syndrome (ACS) patients. We examined the time course of SDB in ACS patients by assessing them within days of the acute event and again after 6 months. Consecutive patients with ACS were asked to voluntarily participate in the study. Patients underwent an overnight polysomnography (PSG) approximately 3 days after the acute event. Patients with an apnea hypopnea index (AHI) > 10/h then underwent another PSG after they were stable (approximately 6 months). Fifty patients were studied. First PSG showed an AHI was 23.1 +/- 3.6/h. A second PSG was performed 6.1 +/- 0.3 months later on 21 patients and showed an AHI > 10/h in the first assessment. The AHI and the obstructive apnea index did not change over the 6 months. However, the central apnea index all was lower at the second assessment.

Allergic bronchopulmonary mycosis (ABPM) is a known complication of asthma and can result in progressive lung damage, respiratory failure and death. Asthma is a common disease in Saudi Arabia and until now the prevalence of ABPM has not been investigated. The aim of this study was to estimate the period prevalence of ABPM due to Aspergillus and Candida in patients with asthma. The setting was an outpatient pulmonary clinic at a university hospital in the central region of Saudi Arabia. Two hundred and sixty-four consecutive patients with asthma (150 or 57% females) were evaluated. All patients were screened for ABPM with skin prick test (SPT) using a panel of fungal antigens. Those with positive skin reactions had further clinical, immunological, respiratory and radiological assessment. ABPM was diagnosed by the presence of a minimum of five of the major criteria suggested by Rosenberg in 1977. Of the 264 patients, 62 (23%) had a positive SPT for at least one fungal allergen, of whom 44 (71%) were females (P=0.01). Seven patients (six females) were diagnosed with ABPM due to Aspergillus and (or) Candida species. Therefore, we estimate the period prevalence of ABPM to be 2.7% (95% confidence interval 1.3-5.4%). A. niger was the commonest fungal species isolated in our group. In conclusion, ABPM is not uncommon in Saudi Arabia and females seem to be more at risk. Because asthma is common, physicians need to have high index of suspicion for this disease and pursue the diagnosis with the appropriate tests.
