Primary nodular amyloidosis of the lung is an uncommon manifestation. The disease runs a benign course, but offers diagnostic problems due to non-specific radiological features entering the big field of the solitary nodule. We describe the case of a 60 year old man with multiple nodules on the left lung operated on diagnostic and therapeutic video-assisted thoracoscopy and discuss the possibilities, if any, of suspecting such a disease through radiologic characteristics along with findings from the patient's history, physical examination and laboratory tests.

Case ReportsSuccessful management of ARDS with bronchopleural fistula secondary to miliary tuberculosis using a conventional ventilator.
Most institutions in India and other developing countries do not have facilities for high frequency ventilation in adults. We report the successful management of a case of ARDS with bronchopleural fistula secondary to miliary tuberculosis using a conventional ventilator and early empiric anti-tubercular therapy.

Extrapleural haematoma (EH) is a rare clinical condition of which four cases are presented. Different etiologies were encountered. ⋯ Surgical exploration was necessary in one patient following pleural biopsy. Medical treatment and clinical observation were the treatment of choice in the remaining three stable patients.

In many societies, marijuana is the second most commonly smoked substance after tobacco. While delta9-tetrahydrocannabinol (THC) is unique to marijuana and nicotine to tobacco, the smoke of marijuana, like that of tobacco, consists of a toxic mixture of gases and particulates, many of which are known to be harmful to the lung. Although far fewer marijuana than tobacco cigarettes are generally smoked on a daily basis, the pulmonary consequences of marijuana smoking may be magnified by the greater deposition of smoke particulates in the lung due to the differing manner in which marijuana is smoked. ⋯ On the other hand, physiologic, clinical or epidemiologic evidence that marijuana smoking may lead to chronic obstructive pulmonary disease or respiratory cancer is limited and inconsistent. Habitual use of marijuana is also associated with abnormalities in the structure and function of alveolar macrophages, including impairment in microbial phagocytosis and killing that is associated with defective production of immunostimulatory cytokines and nitric oxide, thereby potentially predisposing to pulmonary infection. In view of the growing interest in medicinal marijuana, further epidemiologic studies are needed to clarify the true risks of regular marijuana smoking on respiratory health.

Multicenter StudyAsthma is not a common cause of severe chronic respiratory failure in non-smokers: ALOT study.
Little is known about the long-term natural history of asthma and the long-term clinical and functional consequences in non-smoking patients. From a functional point of view, non-smoking asthmatic patients may have a significantly greater decline in forced expiratory volume in one second (FEV1) compared with non-asthmatic subjects and may develop chronic irreversible (fixed) airflow limitation. This has been related to the physiological consequences of chronic airway inflammation causing airway remodeling. However these lesions are all potentially reversible and there is little radiological evidence indicating lung destruction (pulmonary emphysema), which is potentially irreversible, in non-smoking asthmatics. Severe chronic respiratory failure is the major cause of mortality in patients with severe chronic lung diseases. Domiciliary long-term oxygen therapy (LTOT) is an accepted treatment for patients with severe chronic respiratory failure. Our reasoning, therefore, was that if asthma is a cause of severe chronic respiratory failure in non-smokers we should be able to find non-smoking asthmatics within a large population of patients on LTOT. The aim of our study (Asthma and Long-term Oxygen Therapy, "ALOT") was to investigate the prevalence of non-smoking asthmatics in patients on LTOT in a multi-centre, cross-sectional study. ⋯ This data suggests that asthma is an uncommon cause of severe chronic respiratory failure necessitating long-term domiciliary oxygen therapy in non-smokers and supports the current consensus that asthma and COPD are different diseases with differing stages of severity and the concept that long-term avoidance of active smoking is fundamental for the prevention of severe chronic respiratory failure.
