1/371. subcutaneous emphysema with spontaneous pneumomediastinum and pneumothorax in adult dermatomyositis.We describe a 32-year-old patient with adult dermatomyositis who developed dyspnea and worsening of pre-existing infarcted skin lesions of the fingers. Chest radiographs showed diffuse hazy reticulonodular infiltration in both lungs, subcutaneous emphysema, pneumomediastinum, and pneumothorax. The pulmonary symptoms and cutaneous lesions gradually improved with a high dose of prednisolone. Although subcutaneous emphysema and pneumomediastinum occur frequently in association with traumatic disruption of cutaneous and mucosal barriers and assisted ventilation, it has rarely been observed in patients with interstitial pneumonitis in connective tissue diseases. Although dermatomyositis and subcutaneous emphysema are all relatively well-known diseases to dermatologists, the occurrence of spontaneous pneumomediastinum and pneumothorax and subsequent subcutaneous emphysema in connective tissue diseases such as dermatomyositis is unfamiliar. We discuss the possible mechanisms of this condition.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
2/371. Fragile lung in the marfan syndrome.Two cases of the marfan syndrome presented with spontaneous pneumothorax. Both had chest radiographs showing bilateral bullae in the upper lung zones and pulmonary function tests consistent with mild emphysema. There were dereases in forced expiratory flow rates at low lung volumes, carbon monoxide transfer factor, and lung elastic recoil. It is suggested that pneumothorax and bullous emphysema in this syndrome are caused by a weakness in the pulmonary connective tissue framework.- - - - - - - - - - ranking = 7keywords = lung (Clic here for more details about this article) |
3/371. Bilateral pneumothoraces with multiple bullae in a patient with asymptomatic bronchiolitis obliterans 10 years after bone marrow transplantation.A 16-year-old boy developed bronchiolitis obliterans (BO) 10 years after BMT for myelodysplastic syndrome. Although the patient complained of almost no dyspnea on exertion, he had mild hypercapnea with a markedly reduced forced expiratory volume of 0.32 l. Chest x-rays showed occasional bilateral minimal pneumothoraces, which is in accordance with the existence of multiple small bullae found on the pleural surface at video-assisted thoracic surgery. Histologic examination of the biopsied lung revealed BO. This case indicates that BO in adolescence following BMT and possible chronic GVHD may be masked because of lung immaturity at BMT, and BO after BMT may be associated with multiple pleural bullae.- - - - - - - - - - ranking = 2keywords = lung (Clic here for more details about this article) |
4/371. Pectoral myoplasty for recurrent pneumothorax: an extrathoracic solution to an intrathoracic problem.The recurrence rate of spontaneous pneumothorax in patients with underlying lung disease can be as high as 50%. We present a novel method of treatment for recurrent pneumothorax based on the intrathoracic transfer of an extrathoracic muscle flap.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
5/371. Tension pneumothorax.The diagnosis of tension pneumothorax has typically been taught as the presence of hemodynamic compromise with an expanding intrapleural space air mass. This may occur quickly or gradually, depending on the degree of lung injury and respiratory state of the patient. Experimentally, tension pneumothorax is a multifactorial event that manifests a state of central hypoxemia, compensatory mechanisms, and mechanical compression on intrathoracic structures. Studies using animal models suggest that over hypotension is a delayed finding that immediately precedes cardiorespiratory collapse. Recognition of early signs and symptoms associated with tension pneumothorax, e.g., progressive hypoxemia, tachycardia, and respiratory distress, can alert medical personnel to the need for rapid decompression before physiologic decompensation.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
6/371. Catamenial pneumothorax--3 case reports and view of literature.INTRODUCTION: The unusual correlation between chronic recurring spontaneous pneumothorax and the menstrual cycle, was first presented by Maurer in 1958. In our clinic we had 3 cases in 5 years. The anamnesis shows that this syndrome is unknown to many of our colleagues. Not mentioned in several standard textbooks, warrants our attention. methods: In 5 years we had 3 cases of C.P., all of them had already on admission, at least one recurrence; all of them had right sided thoracic pain and dyspnoea. They undergone video-assisted thoracoscopy, with histological examination of diaphragm specimen. Gynaecological consultations was followed by hormonal therapy and follow up. RESULTS: In all 3 cases we found no signs of lung defects or bullae, instead, we identified diaphragm defects of different extension, even a liver prolapse in one of the cases. endometriosis extra genitalis could be diagnosed in only one case which undergone a hysterectomy 8 years before. CONCLUSION: A spontaneous pneumothorax which recurs in correlation with menses has a pathogenesis which concern only women, that is why is referred to as catamenial. Our experience supports the hypothesis, that air in the pleural cavity originates from the peritoneal one, arriving here via uterus and tuba. Beside the symptomatic therapy ther is an etiological one, by inhibition the menstrual cycle. Thoracosurgical intervention could help preventing recurrence, and contributes in clarifying the pathogenesis.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
7/371. Pulmonary lymphangioleiomyomatosis. A study of 69 patients. Groupe d'Etudes et de Recherche sur les Maladies "Orphelines" Pulmonaires (GERM"O"P).Pulmonary lymphangioleiomyomatosis (LAM) is a rare disorder of unknown cause characterized by peribronchial, perivascular, and perilymphatic proliferation of abnormal smooth muscle cells leading to cystic lesions. The hypothesis of hormonal dependence and the effectiveness of hormonal therapy have not yet been demonstrated conclusively, and the prevalence of extrathoracic manifestations and the survival of patients with LAM are somewhat contradictory. A multicentric retrospective study was conducted in an attempt to describe better the initial features, the diagnostic procedures, the associated lesions, and, above all, the management and course of LAM in a large homogeneous series of 69 stringently selected patients, with a majority of cases diagnosed since 1990. The aim of the study, based on a review of the literature, also was to provide a comprehensive view of this uncommon disease. The clinical features were in keeping with previous studies, but we found that exertional dyspnea and pneumothorax were the most common features, and chylous involvement was less frequent. LAM was diagnosed after menopause in about 10% of cases. The onset of LAM occurred during pregnancy in 20% of cases, and a clear exacerbation of LAM was observed in 14% of cases during pregnancy. Pulmonary LAM was diagnosed on lung histopathology in 83% of cases, but renal angiomyolipoma, observed in 32% of our patients, may be a useful diagnostic criterion when associated with typical multiple cysts on chest CT scan or with chylous effusion. Chest CT scan was more informative than chest X-ray (normal in 9% of cases), and may be indicated in spontaneous pneumothorax or renal angiomyolipoma in women of childbearing age. About 40% of the patients had a normal initial spirometry, while an obstructive ventilatory defect (44%), a restrictive ventilatory defect (23%), was observed in other patients. Initial diffusing capacity for carbon monoxide was frequently decreased (82%). Hormonal therapy was administered in 57 patients, but a clear > or = 15% improvement of FEV1 was observed in only 4 evaluable patients, treated with tamoxifen and progestogens (n = 2), progestogen (n = 1), and oophorectomy (n = 1). Probably 1 of the most urgent needs for clinical research in LAM is to test the currently available hormonal treatments in the context of international multicenter prospective controlled studies. pleurodesis was performed in 40 patients. Lung transplantation was performed in 13 patients, 7.8 /- 5.2 years after onset of LAM, in whom the mean FEV1 was 0.57 /- 0.15 L. After a follow-up of 2.3 /- 2.2 years, 9 patients were alive. Mean follow-up from onset of disease to either death or closing date was 8.2 /- 6.3 years. overall survival was better than usually reported in LAM, and Kaplan-Meier plot showed survival probabilities of 91% after 5 years, 79% after 10 years, and 71% after 15 years of disease duration.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
8/371. Contralateral tension pneumothorax following unilateral chest tube drainage of bilateral pneumothoraces in a heart-lung transplant patient.Bilateral pneumothoraces can result from unilateral air leak after heart-lung transplantation. The recommended initial management of such patients is insertion of a unilateral chest tube. We report a patient who developed bilateral pneumothoraces after undergoing transbronchial biopsies 2 years after a heart-lung transplant. The unilateral chest tube failed to drain the contralateral pneumothorax and a tension pneumothorax developed. The advocated approach should be used with caution.- - - - - - - - - - ranking = 6keywords = lung (Clic here for more details about this article) |
9/371. Delayed pneumothorax and hydrothorax with central venous catheter migration.We report a case of delayed pneumothorax, central venous catheter migration and iatrogenic hydrothorax in a 22-year-old female. The left subclavian central venous catheter initially transfixed the lung apex; pneumothorax occurred 24 h later following initiation of positive pressure ventilation. Lung collapse as a result of the pneumothorax caused catheter migration and hydrothorax. Catheter removal and chest drainage led to an uneventful recovery.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
10/371. Late pleuropulmonary aspergillosis after the treatment of pneumothorax: report of three cases.A bullectomy for spontaneous pneumothorax is often combined with pleurodesis to prevent recurrence. A recurrent or progressive residual bullous lung beneath adhesive pleura neovascularized from the chest wall may be affected by aspergillosis. Of the 12 patients with pulmonary aspergillosis secondary to bullous lung disease treated surgically at our hospital since 1974, 3 underwent a bullectomy with pleurodesis for spontaneous pneumothorax. The presenting symptoms in all cases were hemosputum. aspergillus lesions affected the patients in the right upper lobe, the left apical segment, and both apical segments at 16, 9, and 13 years, respectively, after a bullectomy. Angiograms demonstrated hypervascularization in the intercostal and internal thoracic arteries, as well as in the bronchial branches. Catheter embolization for airway bleeding was not effective in 1 patient. Four operations, including an emergency procedure for massive intrapulmonary bleeding, were performed. These included a right upper lobectomy followed by a left upper segmentectomy at second-look operation in 1 patient who required bilateral chest wall resections. All patients survived the operations. Intraoperative bleeding ranged between 700 and 3 500 ml (1 543 ml on average), and bleeding foci were mainly from the chest wall, with hypervascularization stemming from the ipsilateral chest wall. postoperative complications included pleural space hemorrhaging and a bronchopleural fistula, both of which required additional chest wall resections. patients with bullous lung disease late after a bullectomy with pleurodesis may thus be associated with complex pleuropulmonary aspergillosis, which requires surgical therapy concomitant with a chest wall resection.- - - - - - - - - - ranking = 3keywords = lung (Clic here for more details about this article) |
