Bronchogenic cysts (BCs) are uncommon congenital anomalies. Due to the inherent complications, the mere presence of a BC should warrant surgical therapy. Partial excision of these structures leads to recurrence. Complete surgical excision using a thoracotomy or video-assisted thoracic surgery is the goal. We report a case of recurrent bronchogenic pseudocyst 24 years after initial excision. This case supports the argument for complete surgical excision of BCs at the time of diagnosis.

Fibrotic process affecting the lung and other tissues is characterized by stimulation of fibroblast proliferation and connective tissue deposition. Conventional therapy consisting of glucocorticoids or cytotoxic agents is usually ineffective in blocking progression of disease. Potential new therapies have emerged from the use of animal models of pulmonary fibrosis and recent advances in the cellular and molecular biology of inflammatory reactions. Such therapies involve the use of substances directed against the action of certain growth factors, cytokines, or oxidants that are elaborated during the fibrotic reaction. In this article, we review possible therapeutic applications of these advances.

We describe five patients with severe nocturnal cough and daytime somnolence in whom the coughing attacks are triggered by assuming the supine body position. Quantity and quality of the nocturnal cough were evaluated in the sleep laboratory with and without nasal continuous positive airway pressure (N-CPAP). Air flow characteristics were assessed using flow volume and airway resistance loops. Airway anatomy was evaluated bronchoscopically. In all five patients, the cough had a barking quality. Flow-volume loops showed an expiratory collapse phenomenon in two of the patients. Endoscopically, all five patients had signs of airway collapse. All patients had difficulty falling asleep because of coughing and were awakened by it frequently. Sleep times ranged from 2.5 to 4.5 h per night. With N-CPAP pressures ranging from 5 to 13 cm H2O, all five patients had clinically significant improvement in their symptoms. Their sleep times increased to a range of 5 to 7.5 h per night and the daytime somnolence markedly improved or resolved. All five patients requested a N-CPAP unit for home use. We conclude that a cough that is predominantly associated with or exacerbated by the supine body position may be treated effectively with N-CPAP.

A 54-year-old woman developed signs and symptoms consistent with reflex sympathetic dystrophy in her left upper extremity following arterial puncture. Diagnosis was confirmed by bone scan, and sympathetic blockade with intravenous regional bretylium completely relieved her severe, intractable pain.

We report a case of complete torsion of the right lung induced by transthoracic needle biopsy. While a delay in diagnosis occurred, viability of the torsed lung was maintained, thereby allowing for effective surgical repair.

A case of mediastinal malignant epithelioid schwannoma (MES) is reported. The tumor probably arose in the vagal nerve, and the trachea was involved. A few months after excision of the primary tumor, multiple metastases appeared in lung, cervical spine, and neck lymph nodes. Microscopically, the tumor showed a highly cellular area resembling melanoma or carcinoma. Immunolabeling was done for S-100 protein, keratin, and melanoma-associated antigen. Examination of the entire lesion and in situ characteristics of the tumor involving the vagal nerve were helpful in making the correct diagnosis. Mediastinal MES, to our knowledge, has not been reported to date in the English-language medical literature.

We report an 18-year-old patient with severe mitral stenosis complicated by right lower lobe pneumonia, sepsis, and shock. Intractable low cardiac output led to an emergency percutaneous balloon mitral valvotomy in a patient, resulting in immediately improved hemodynamic parameters. We are unaware of another report of percutaneous balloon mitral valvotomy performed in a patient with sepsis and shock. This case supports previous isolated reports of the benefit from emergency percutaneous balloon mitral valvotomy in critical situations where thoracotomy is not possible due to coexisting medical problems.
