“…Pneumothorax is a common thoracic disorder involving an abnormal collection of air in the space between the lungs and the chest wall 1 . A large volume of air in the pleural cavity can lead to tension pneumothorax, which compress the lungs and heart, causing shock and often death 2 . Therefore, it is important to check for the presence or absence of pneumothorax by taking a chest X-ray when a patient complains of chest pain and dyspnea.…”

The purpose of this study was to evaluate the diagnostic performance achieved by using fully-connected small artificial neural networks (ANNs) and a simple training process, the Kim-Monte Carlo algorithm, to detect the location of pneumothorax in chest X-rays. A total of 1,000 chest X-ray images with pneumothorax were taken randomly from NIH (the National Institutes of Health) public image database and used as the training and test sets. Each X-ray image with pneumothorax was divided into 49 boxes for pneumothorax localization. For each of the boxes in the chest X-ray images contained in the test set, the area under the receiver operating characteristic (ROC) curve (AUC) was 0.882, and the sensitivity and specificity were 80.6% and 83.0%, respectively. In addition, a common currently used deep-learning method for image recognition, the convolution neural network (CNN), was also applied to the same dataset for comparison purposes. The performance of the fully-connected small ANN was better than that of the CNN. Regarding the diagnostic performances of the CNN with different activation functions, the CNN with a sigmoid activation function for fully-connected hidden nodes was better than the CNN with the rectified linear unit (RELU) activation function. This study showed that our approach can accurately detect the location of pneumothorax in chest X-rays, significantly reduce the time delay incurred when diagnosing urgent diseases such as pneumothorax, and increase the effectiveness of clinical practice and patient care.

“…Studies have shown numerous approaches offered by different guidelines and associations. According to the American College of Chest Physicians (ACCP), the British Thoracic Society (BTS), and the Spanish Society of Pulmonology and Thoracic Surgery, the initial management of the primary spontaneous pneumothorax is directed to remove air from the pleural space and prevent recurrences [1,38]. Treatment options for primary spontaneous pneumothorax go from simple observation, aspiration with a catheter, insertion of a chest tube, pleurodesis, thoracoscopy, video-assisted thoracoscopic surgery (which is one of the most studied approaches) to thoracotomy.…”

“…Pneumothorax is defined as an abnormal collection of air in the pleural cavity, which is a potential space between the two pleurae (visceral and parietal) of the lungs [1]. Itard, a student of Laennec, first coined pneumothorax in 1803, but it was not until 1932 that it was realized that spontaneous pneumothorax was not always caused by tuberculosis.…”

Primary spontaneous pneumothorax (PSP) is a common disease in medical practice that affects young healthy people with a significant recurrence rate. PSP is the presence of air in the pleural space not caused by injury or medical intervention. Some risk factors include male gender, age, and smoking. Classic clinical presentation starts with acute-onset chest pain and shortness of breath. Physical examination can be normal in small pneumothoraces, but in larger pneumothoraces, breath sounds and tactile fremitus are typically decreased or absent, and percussion is hyperresonant. Chest X-ray can help confirm the diagnosis. Evacuation of air from the pleural cavity and prevention of future recurrences are the primary goals of treatment and depend on the patient's presentation. Initial deciding factors to direct the management are first-time or recurrent spontaneous pneumothorax and size of the pneumothorax. Treatment may include conventional chest tube drainage, video-assisted thoracoscopic surgery (VATS), or open surgery.

“…The approach to managing of catamenial pneumothorax is multi-faceted often involving a respiratory physician, thoracic surgeon, gynaecologist, radiologist and histopathologist 3,6,10,13,14 . In the first instance of spontaneous pneumothorax in clinically stable patients with small catamenial pneumothorax (<2-3cm on CXR), patients should be observed over ≥ 6 hours period, given high flow oxygen to aid resorption of pleural air, have a repeat CXR prior to discharge, as well as an outpatient appointment in 2-4 weeks 25 . Moderate-large catamenial pneumothorax requires needle aspiration or chest tube insertion and longer duration of hospital stay 15 .…”

Primary spontaneous pneumothorax is defined as the presence of air in the pleural space with no precipitating cause and is four times less likely to occur in women than in men1,2. Common causes for spontaneous pneumothorax in females include: interstitial pneumonia, primary lung cancer and lung metastasis, and asthma3. An uncommon cause for secondary spontaneous pneumothorax is catamenial pneumothorax, which is associated with thoracic endometriosis. The word “catamenial” is derived from the greek word “katamenios” meaning monthly recurrence.4 Catamenial pneumothorax refers to recurrent spontaneous pneumothorax during menstruation in the absence of concomitant respiratory disease5.
