The lack of a clear cause means that diagnosis and treatment is difficult. The disease is believed to be largely undiagnosed or misdiagnosed, leaving the true frequency unknown in the general population. Catamenial pneumothorax is defined as at least two episodes of recurrent pneumothorax corresponding with menstruation.
In a survey of 318 patients who indicated that they had had at least one pregnancy, 163 responded to a second survey focusing on lung collapse. [145] A total of 38 patients reported a pneumothorax with pregnancy, consistent with an incidence of pneumothorax in pregnancy of at least 10% (38 of 318).
Thoracic endometriosis is characterised by onset of the following clinical symptoms within 24 hours prior to and 72 hours after onset of menses. Catamenial pneumothorax: this is the most common clinical manifestation, present in 80% of cases. Catamenial pneumothorax is defined as a recurrent pneumothorax that occurs within the first 72 hours ...
It is rare for a PSP to cause a tension pneumothorax. [12] Secondary spontaneous pneumothoraces (SSPs), by definition, occur in individuals with significant underlying lung disease. Symptoms in SSPs tend to be more severe than in PSPs, as the unaffected lungs are generally unable to replace the loss of function in the affected lungs.
The underlying cause for CPAM is unknown. It occurs in approximately 1 in every 30,000 pregnancies. [1] In most cases the outcome of a fetus with CPAM is very good. In rare cases, the cystic mass grows so large as to limit the growth of the surrounding lung and cause pressure against the heart.
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.

It is the most common cause of respiratory distress in term neonates. [2] [3] It consists of a period of tachypnea (rapid breathing, higher than the normal range of 30–60 times per minute). Usually, this condition resolves over 24–72 hours. Treatment is supportive and may include supplemental oxygen and antibiotics.
The condition only causes symptoms if the visceral pleura is affected. [5] Although fibrothorax may not cause any symptoms, people affected by the disorder may report shortness of breath . [ 6 ] Persistent, recurrent pleural effusions are a possible symptom, caused by the persistent cavity formed by the hardening pleura around the original ...
