On physical examination, crepitus (subcutaneous emphysema) is commonly present in the chest wall or neck.[clinicaladvisor.com]
An X ray of the chest is the test that absolutely confirms that a pneumothorax or pneumomediastinum is present. It can also provide some information as to how much air and compression on the lungs has occurred.[mybabies1.blogspot.com]

The patient may remain asymptomatic or may have symptoms such as chest pain, dyspnea, dysphagia, dysphonia, coughing, and/or neckswelling. Our patient had neckswelling and dysphagia after coughing.[mjdrdypu.org]
Furthermore, it has been shown experimentally that exposure to cigarette smoke produces marked changes in the vascular system of the lungs of rats. 3 This led us to suspect that the lung parenchyma of human beings might be directly affected by chronic irritation[nejm.org]
Irritating microbubbles can then cause vasospasm, with resulting neurological damage or myocardial infarction .[alpfmedical.info]
Therefore, we cannot rule out the possibility of spontaneous rupture due to increased intra-thoracic pressure caused by irritation during the postoperative recovery.[e-aps.org]
Chemical pleurodesis is the instillation of either sterile talc or erythromycin to produce irritation or inflammation of the pleura.[thoracics.org]
Someone who has upper airway irritation as a result of post-nasal drainage (which I often have for WEEKS after an upper respiratory infection) is at higher risk for reverse block and sinus damage than from pulmonary overexpansion injury.[scubaboard.com]

Thus, patients without (1) fever 38 C; (2) oxygen desaturation Thus, a better understanding of this condition would have avoided unnecessary irradiation of this young woman (the only workup the patient needed was a simple Chest X-ray Study).[link.springer.com]

Effective secretion clearance, treatment of infection, and, most importantly, reduction of airway pressure are fundamental to management.[alpfmedical.info]
The prognosis is much better for babies weighing over 1500 g. Prevention Antenatal corticosteroids (dexamethasone) accelerate fetal surfactant production and lung maturation.[patient.info]
Prognosis If an infant born with RDS is not promptly treated, lack of an adequate oxygen supply will damage the body's organs and eventually cause them to stop functioning altogether. Death is the result.[healthofchildren.com]
Prognosis Up to 50% of patients who suffer from a pneumothorax will have another or a recurring pneumothorax. However, there are no long-term complications after successful treatment.[physio-pedia.com]
What is the prognosis for patients managed in the recommended ways? The majority of cases of pneumomediastinum are self-limited and resolve without invasive therapeutic measures.[clinicaladvisor.com]
Patients with secondary causes of pneumomediastinum usually present with a history that readily suggests an etiology of prior trauma or procedural instrumentation.[clinicaladvisor.com]

Epidemiology The incidence and severity are related inversely to the gestational age of the infant. It affects approximately one half of infants born at 28-32 weeks of gestation. It may (rarely) occur at term.[patient.info]

The results confirm the intimate relationship of pulmonary barotrauma, as reflected by the occurrence of alveolar rupture during positive pressure inflation of the lungs, to the subsequent development of bronchopulmonary dysplasia and that prevention[ncbi.nlm.nih.gov]

The amount of atelectasis, pulmonary congestion or obstruction that prevents expansion of lung is clinically not quantitatively measurable, so that no exact rule for time and pressures can be established that will be completely safe.[pediatrics.aappublications.org]
Prevention of injury to the cervical fascia during facial bone contouring surgery should be the first priority.[e-aps.org]
Prevention The best way of preventing RDS is to delay delivery until the fetal lungs have matured and are producing enough surfactant, generally at about 37 weeks of pregnancy.[healthofchildren.com]
