Negative-pressure ventilation (NPV) is a form of noninvasive ventilation that has been recently utilized in pediatric acute respiratory failure. Negative-pressure ventilators apply negative pressure onto the chest wall via a cuirass to recruit areas of atelectasis. Continuous negative extrathoracic pressure, the most common mode, is similar to CPAP, where negative pressure is maintained at a constant level throughout the respiratory cycle while patients initiate their own breaths and continue to breathe spontaneously throughout.

Spontaneous pneumothorax is a classical medical condition encountered in emergency centers, and by primary care and respiratory physicians. The traditional distinction between primary and secondary pneumothorax, although old and increasingly blurred, still allows to guide initial management and to determine whether pleurodesis is indicated. In case of spontaneous pneumothorax, a targeted family history is essential because it can suggest the presence of a genetic syndrome as the underlying cause of the pneumothorax, a condition often associated with a high risk of pneumothorax recurrence, and the occurrence of extrathoracic manifestations which may be serious if recognized late.

Lymphangioleiomyomatosis (LAM) is an ultra-rare, slowly progressive neoplastic cystic disease, belonging to the group of PEComas. It can occur sporadically or associated to tuberous sclerosis complex disease and affects mainly women in child-birth age. Dyspnoea is the most frequent symptom referred to the time of diagnosis, however spontaneous pneumothorax may be a typical presentation associated to extrathoracic manifestations, such as renal angiomyolipomas.

Lung herniation is a rare clinical entity defined by extrathoracic protrusion of the lung or lung tissue due to a weakness in the thoracic wall. We present here a case of a 72-year-old male who presented with a spontaneous lung herniation, which occurred as a result of a ventral luxation of the third rib from the sternocostal joint due to vigorous coughing. The defect was repaired through anterolateral thoracotomy, reposition of the lung and approximating the ribs using heavy sutures.

Article Synopsis
- The study investigates the effectiveness of Effort of Breathing (EOB) calculations as an alternative to Work of Breathing (WOB) measurements in nonhuman primates during increased inspiratory resistance, mimicking upper airway obstruction.
- Through the use of Respiratory Inductance Plethysmography (RIP) and other measurements, researchers found that EOB and WOB showed strong correlations, indicating similar responses to higher resistive loads.
- The findings suggest that EOB could serve as a reliable substitute for WOB, especially in scenarios where spirometry is unavailable, offering new monitoring opportunities for non-invasive ventilation.
