Subcutaneous emphysema is a type of air leak in which air accumulates within the subcutaneous layer of the skin underneath the dermal layers. The accumulation of air can be seen on imaging in relevant body areas such as the abdomen, chest, face, or neck. During physical examination, crepitus, the sensation or sound of crackling upon palpation, is the most common associated finding. Various causes for subcutaneous emphysema exist, with one such cause being thoracostomy or chest tube placement. The trocar technique, in particular, has been associated with greater complications when compared to other techniques. Here, we present a case of subcutaneous emphysema in a neonate occurring after placement of a chest tube using the trocar technique. At this time, much of the knowledge regarding subcutaneous emphysema related to chest tube placement is in the adult population. Clinicians should be aware of this complication in neonates as the body of knowledge regarding this topic continues to grow.

Stress cardiomyopathy (SCM) is a clinical phenomenon presenting symptoms suggestive of acute coronary syndrome and defined by acute, but transient, electrocardiogram (ECG) changes and left ventricular wall motion abnormalities. However, no obstructive coronary lesion is identified on catheterization, and pathognomic echocardiogram findings are typically encountered. Multiple causes have been posited in the literature (e.g., severe stress, anxiety, pain, comorbid illness, trauma). We present the case of a 46-year-old female who presented to the emergency department (ED) for delayed left-sided hemothorax (six weeks following a high-speed motor vehicle collision) and developed an acute SCM following large-bore chest tube placement. To our knowledge, no prior cases have been reported immediately following thoracostomy tube placement and hemothorax drainage in the ED setting. We explore possible mechanistic explanations related to our case, which adds to the existing literature on the subject.

A 34-year-old female smoker, with a history of pelvic endometriosis, presented with initial symptoms of shortness of breath and a choking sensation. She was found to have a right pneumothorax on chest x-ray. Over the next eight months, she ultimately underwent three tube thoracostomies, two video-assisted thoracoscopic surgeries (VATS), wedge resection, and repeated pleurodesis due to pneumothorax recurrence. She was seen multiple times post-surgically with the focus of treatment being smoking cessation rather than contraceptive therapy, despite an early follow-up visit noting that the initial symptoms coincided with her menstruation. The purpose of this article is to bring attention to this rarely diagnosed condition. With added awareness and understanding of the underlying causes and available treatments, medical providers could likely spare many women from similar experiences and dramatically improve the quality of their lives.

A 45-year-old male presented to the emergency department after being found unresponsive. Vitals, laboratory findings, and chest X-ray revealed concern for tension empyema. Thoracostomy was performed, and hemodynamics subsequently improved. Later, Prevotella denticola was cultured. This is the first known reported case of tension Prevotella denticola empyema.
