Spontaneous secondary pneumothorax due to cannabis-induced bullous lung disease: a case report.

Marijuana use has grown rapidly in the last decade with a prevalence greater than that of cocaine and opioids. With its increasing recreational and medical use, potential adverse outcomes from heavy use may be associated with bullous lung disease and spontaneous pneumothorax. This case report has been reported in line with the SCARE Criteria. Case presentation: The authors describe a case of an adult male with a past medical history of spontaneous pneumothorax and long-standing marijuana use presenting with dyspnoea who was found to have a secondary spontaneous pneumothorax requiring invasive treatment. Clinical discussion: The aetiology of lung injury due to heavy marijuana smoke may be from direct tissue injury from inhaled irritants and the method of which marijuana smoke is inhaled compared with tobacco smoke. Conclusion: Chronic marijuana use should be considered when evaluating structural lung disease and pneumothorax in the setting of minimal tobacco use.

Excision of a giant lung bulla in a child: Repair of bronchial leaks using redundant bullous wall/membrane.

Large lung bullae are rare in children. We report a rare case of a large bulla in the right lung causing compression of the underlying lung with a shift of the mediastinum to the contralateral side. Excision of the bulla was done and a novel technique was used in the repair of bronchial air leakage sites with part of the bullous wall/membrane. The patient recovered well with re-expansion of the underlying collapsed lung.

Infected lung bulla caused by Neisseria elongata: A case report.

Neisseria elongata is a rod-shaped, Gram-negative, aerobic bacterium that is part of the normal oral bacterial flora. Although previously considered a non- or low-pathogenic organism, the development of bacterial detection methods has resulted in increased reports of N. elongata infections such that it has recently been recognized as a causative agent of serious infections even in non-immune-compromised patients. A 77-year-old man with rheumatoid arthritis-associated interstitial lung disease, chronic obstructive pulmonary disease, and diabetes mellitus was diagnosed with a nodule in the left lower lobe of his lung. Thoracoscopic wedge resection was performed, and pus was discharged from the specimen. Mass spectrometry of the swab culture revealed N. elongata. The patient's postoperative course was uneventful, and he was doing well without recurrence at 13 months after surgery. Since N. elongata is an oral bacterial flora, the patient consulted a local dentist, and decayed teeth were extracted. Most of the reported cases of serious N. elongata infections have described infective endocarditis. This is the first report of infected lung bulla due to N. elongata infection, which demonstrates a new pathogenicity.

A Refractory, Infected Lung Bulla and an Abscess Treated Using Percutaneous Drainage in a Patient With Human T-Lymphotropic Virus Type 1-Associated Myelopathy.

We present a case of a 54-year-old Japanese woman with established human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy who developed a refractory infected lung bulla and lung abscess caused by Pseudomonas aeruginosa, Methicillin-resistant Staphylococcus aureus, and Aspergillusspecies. Since antibiotic treatment alone failed to resolve the infection, percutaneous drainage of the infected bulla was performed. Although a prolonged treatment period was necessary, the infected lung bulla and the lung abscess were eventually resolved. During her illness, the patient also developed arthritis, possibly related to the HTLV-1 infection. Thus, persons infected with HTLV-1 can develop refractory infections, myelopathy, and arthritis. Percutaneous drainage is an option to treat refractory infected lung bullae.

Loss of consciousness during air travel: A case of lung bullae.

A giant lung bulla occupies at least a third of the lung space. We present a middle-aged man who lost consciousness during an air flight for 30 minutes, without any respiratory symptoms. An incidental finding on chest x-ray revealed a giant bulla and a chest computed tomography imaging confirmed the diagnosis and ruled out a tension pneumothorax. A giant lung bulla is an uncommon cause of loss of consciousness and may be suspected if it occurs during air travel.

Multiple infected lung bullae associated with Mycobacterium intracellulare in a Japanese man.

Mycobacterium avium complex (MAC)-infected lung bulla was a rare type of pulmonary non-tuberculous mycobacterial (NTM) infection. A 29-year-old man with a history of tetralogy of Fallot was admitted to our hospital because of a high fever and left chest pain. Chest computed tomography showed two bullae with intrabullous fluid in both the lower lobes and centrilobular small nodular shadow in the right upper lobe and the left lower lobe. Culture of bronchoscopic washing specimen from the right upper lobe bronchus and left lower lobe one and purulent fluid drained from the bulla in the left lower lobe revealed Mycobacterium intracellulare. Percutaneous drainage from the left bulla and anti-NTM treatment were performed. Afterwards, symptoms improved and two intrabullous fluid disappeared. Therefore, a diagnosis of multiple infected lung bullae associated with M. intracellulare was made. This is the first documented case of multiple infected lung bullae associated with MAC.

Hemoptysis and a Newly Formed Lung Bulla in a Case of Convalescent COVID-19 Pneumonia.

Coronavirus disease 2019 (COVID-19) is a novel infectious disease affecting the general population worldwide. A fever and cough are the common clinical presentations of COVID-19. In most of these patients, computed tomography (CT) shows bilateral peripheral ground-glass opacities. We herein report a case of hemoptysis and lung bulla in the convalescent phase of COVID-19. Based on the clinical observations, alveolar destruction was likely associated with hemoptysis and bulla formation. Therefore, we suggest the follow-up of COVID-19 patients whose clinical parameters indicate alveolar damage, even after their symptoms improve.

Neumotórax espontáneo debido a bulas subpleurales: presentacion de un caso / Spontaneous pneumothorax and subpleural bulla: case report

Pneumothorax is defined as the presence of air within the pleural cavity. It may be traumatic, iatrogenic, spontaneous secondary or primary. In the latter cause, the most frequent are subpleural and apical bulla in longiline patients, with connective tissue diseases and smokers. Treatment should be conservative in patients who present a small pneumothorax. Instead, a probe should be installed if it is greater. In the presence of frequent recurrences or persistent air leakage, pleurodesis should be considered, or resection of the bullous should be practiced. In this article we review a patient with Elhers Danlos syndrome, who presents a primary spontaneous pneumothorax due to subpleural bulla

El neumotórax se define como la presencia de aire dentro de la cavidad pleural. Puede ser traumático, iatrogénico, espontáneo secundario o primario, dentro de esta última causa la más frecuente son las bulas subpleurales y apicales, en pacientes longilíneos, portadores de enfermedades del tejido conectivo y fumadores. En neumotórax pequeños el tratamiento debe ser conservador, en cambio en los de mayor cuantía se debe proceder a la instalación de una sonda pleural. Frente a recidivas frecuentes o persistencia del escape aéreo, se debe considerar la pleurodesis o bien practicar la resección de las bulas.En el presente artículo se reporta a un paciente con síndrome de Elhers Danlos que presenta un neumotórax espontáneo primario debido a bulas subpleurales.

Doenças pulmonares císticas adquiridas: [revisão] / Acquired cystic pulmonary diseases: [review]

As lesões pulmonares císticas adquiridas fazem parte do contexto de sinais e sintomas de várias morbidades, podem ser sintomáticas ou assintomáticas e, às vezes, desaparecem espontaneamente. Realizou-se uma revisão bibliográfica com o objetivo de abordar as principais causas de lesões pulmonares císticas adquiridas e fornecer uma visão simples e objetiva das doenças relacionadas às lesões aeradas, na tentativa de dirimir as dificuldades com relação ao diagnóstico etiológico.

Acquired cystic lung lesions are part of the set of signs and symptoms of various conditions, and they may be symptomatic or asymptomatic and sometimes they disappear spontaneously. A literature review was carried out aiming at approaching the main causes of acquired cystic lung lesions, thus providing a simple and objective vision of diseases related to aerial lesions, in an attempt of overcome difficulties concerning the etiologic diagnosis.
