Catamenial pneumothorax (CP) is a rare entity of spontaneous, recurring pneumothorax in women. We aim to discuss the etiology, clinical course, and surgical treatment of a 42-year-old woman with CP. This patient had a right-sided spontaneous pneumothoraces occurred one week after menses. She had under-gone video-assisted thoracoscopic surgery (VATS) because of a persistent air leak under chest tube. VATS revealed multiple diaphragmatic fenestrations with an upper right nodule. Defects were removed and a large part of the diaphragm was resected...

This paper describes the utilization of vacuum to fill complex microchannels with liquid metal. Microchannels filled with liquid metal are useful as conductors for soft and stretchable electronics, as well as for microfluidic components such as electrodes, antennas, pumps, or heaters. Liquid metals are often injected manually into the inlet of a microchannel using a syringe. Injection can only occur if displaced air in the channels has a pathway to escape, which is usually accomplished using outlets. The positive pressure (relative to atmosphere) needed to inject fluids can also cause leaks or delamination of the channels during injection...

BACKGROUND: In chemical pleurodesis for managing pulmonary air leak, tetracycline derivatives are commonly used, and their effectiveness has been established in many studies. Recently, a Viscum album extract was used in chemical pleurodesis. We compared the effects of V. album with those of a tetracycline derivative (doxycycline) to demonstrate the therapeutic effectiveness of the V. album extract in chemical pleurodesis for managing pulmonary air leak. METHODS: Between October 2010 and October 2016, chemical pleurodesis was performed using doxycycline in 40 patients and the V...

A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchoscopic examination, proper tube location was confirmed. Bronchodilator nebulization and steroid injection were attempted with no effect...

BACKGROUND: This study aimed to retrospectively evaluate the use of sugammadex in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy. METHODS: Data were obtained from medical record review of patients who underwent VATS lobectomy from January 2013 to November 2014. Fifty patients were divided into two groups: the sugammadex group (group S, n = 19) was administered sugammadex 2 mg/kg, while the pyridostigmine group (group P, n = 31) received pyridostigmine 20 mg with glycopyrrolate 0...

Reginald M Penner
Hydrogen gas (H2) is odorless and flammable at concentrations above 4% (v/v) in air. Sensors capable of detecting it rapidly at lower concentrations are needed to "sniff" for leaked H2 wherever it is used. Electrical H2 sensors are attractive because of their simplicity and low cost: Such sensors consist of a metal (usually palladium, Pd) resistor. Exposure to H2 causes a resistance increase, as Pd metal is converted into more resistive palladium hydride (PdHx). Sensors based upon Pd alloy films, developed in the early 1990s, were both too slow and too insensitive to meet the requirements of H2 safety sensing...

BACKGROUND: Traditionally chest tubes are set to -20 cm H2O wall suctioning until removal to facilitate drainage of blood, fluid, and air from the pleural or mediastinal space in patients after open heart surgery. However, no clear evidence supports using wall suction in these patients. Some studies in patients after pulmonary surgery indicate that using chest tubes with a water seal is safer, because this practice decreases duration of chest tube placement and eliminates air leaks. OBJECTIVE: To show that changing chest tubes to a water seal after 12 hours of wall suction (intervention) is a safe alternative to using chest tubes with wall suction until removal of the tubes (usual care) in patients after open heart surgery...

Secondary spontaneous pneumothorax can be difficult to manage especially in patients with advanced lung disease and respiratory failure. Such patients are unfit for surgery and may endure prolonged hospital stays with chest drains in situ. We describe two such cases where the air leak was persistent despite conventional management. Ambulatory devices which we ordinarily use to manage pneumothoraces in patients with a good lung reserve, were employed as a palliative measure. The strategy not only allowed the patients to return home, but also resulted in healing of the air leak which had persisted with conventional management...

Patients with severe cystic lung disease are considered to be at risk for cyst rupture during air travel because of the possibility of increase in cyst size and impaired equilibration of pressure between the cysts and other parts of the lung. This may have clinically devastating consequences for the patient but may also result in significant costs for emergency alteration of flight schedule. We report the use of a hypobaric chamber to simulate cabin pressure changes encountered on a commercial flight to assess the safety to fly of a child with severe cystic lung disease secondary to Langerhans cell histiocytosis...

Tracheobronchomegaly (also called Mounier-Kuhn syndrome) is a rare disease characterized by flaccid and markedly dilated trachea and main bronchi on inspiration with narrowing or collapse on expiration or cough. It is associated with recurrent lower respiratory tract infection. A 75-year-old man with unexpected giant tracheomegaly had a significant peritubal air leak which impeded an operation. Lumbar epidural anesthesia was performed for a subsequent operation without any sequela. Careful evaluation with chest radiography is basic to exclude a large airway...

We report a 21-month-old child with spontaneous pneumomediastinum (PM), emphysema, and pulmonary bullae caused by Mycoplasma pneumonia (M. pneumoniae) pneumonia. The patient presented with stubborn dyspnea and wheezing although received integrated treatment, including anti-infection, anti-inflammation, and intravenous immunoglobulin. This case was unique in that pulmonary bullae kept increasing. PM and emphysema were refractory in our patient, which have been reported as benign and limited. Surgical intervention was implemented to ultimately cure the case...

A 59-year-old man with bilateral apical emphysema underwent a double lung transplant for end-stagechronic obstructive pulmonary disease leaving remnant right apical native tissue due to pleural adhesions. Initial postoperative course was uneventful until the chest drains were removed. This revealed a small pneumomediastinum, which progressively increased in size causing gross surgical emphysema. Re-insertion of the chest drain stabilised the patient so that the cause could be identified and corrected. Two bronchoscopies excluded anastomotic dehiscence as a cause...

The clinical presentation of pneumothorax is highly variable. Spontaneous pneumothoraces may present with subtle symptoms when a small air leak is present, but can progress to hemodynamic instability in the setting of tension physiology. The etiologies are broad and the severity can vary greatly. A trauma patient with a pneumothorax may also have the added complexity of other potentially life-threatening injuries. While there is a wealth of evidence-based guidelines for the management of pneumothoraces in the adult literature, the approach to pediatric patients is largely extrapolated from that literature without a significant evidence base...

Pulmonary Langerhans cell histiocytosis (LCH) is a rare disease, affecting usually young people. The course of the disease is variable. In some pulmonary LCH patients a severe lung destruction and progression in spite of chemotherapy is observed, but in others just a cessation of smoking induces a regression of the disease. In the present study we seek to determine the influence of pregnancy on pulmonary function in LCH patients, an unchartered area of research. We addressed the issue by investigating eight pregnant women out of the 45 women hospitalized with the diagnosis of pulmonary LCH in the period from 2000 to 2015...

BACKGROUND: Prolonged air leak and high-volume pleural drainage are the most common causes for delays in chest tube removal following lung resection. While digital pleural drainage systems have been successfully used in the management of post-operative air leak, their effect on pleural drainage and inflammation has not been studied before. We hypothesized that digital drainage systems (as compared to traditional analog continuous suction), using intermittent balanced suction, are associated with decreased pleural inflammation and postoperative drainage volumes, thus leading to earlier chest tube removal...

Robotic-assisted pulmonary lobectomy can be considered for patients fit for conventional lobectomy. Contraindications include prohibitive lung function or medical comorbidities, multistation N2, gross N2 disease, or evidence of N3 disease. Team training, familiarity with equipment, troubleshooting, and preparation are critical for successful robotic lobectomy. Similar to video-assisted thoracoscopic surgery (VATS) lobectomy, robotic lobectomy is associated with decreased blood loss, blood transfusion, air leak, chest tube duration, duration of stay, and mortality compared with thoracotomy...
