Use of pembrolizumab in MSI-high uterine leiomyosarcoma; a case report and review of the literature.

•Overall prognosis of uterine leiomyosarcoma (ULMS) is poor with a low 5-year survival rate.•Microsatellite instability (MSI)-high ULMS is not well documented in current literature.•Immune checkpoint inhibitors such as pembrolizumab have been shown to have good efficacy in treating MSI-high solid tumors.•Targeting MSI-high ULMS with pembrolizumab can potentially maintain a patient's quality of life and extend overall survival.

Interdigitated microelectronic bandage augments hemostasis and clot formation at low applied voltage in vitro and in vivo.

Hemorrhage or uncontrolled bleeding can arise either due to a medical condition or from a traumatic injury and are typically controlled with the application of a hemostatic agent. Hemostatic agents are currently derived from animal or human products, which carry risks of blood borne infections and immune dysregulation. Therefore, the need exists for novel biomedical therapies not derived from animal or human products to achieve hemostasis. Accordingly, we created an interdigitated microelectronic bandage that applies low voltage electrical stimulation to an injury site, resulting in faster clot formation without excessive heating, accelerated fibrin formation, and hemostasis overall. Our interdigitated microelectronic bandage found fibrin formed 1.5× faster in vitro. In vivo, total cessation of bleeding was 2.5× faster, resulting in 2× less blood loss. Electricity has been used in medical applications such as defibrillation, cauterization, and electrosurgery, but scant research has focused on hemostasis. Here we report a novel surface treatment using an interdigitated microelectronic device that creates rapid hemostasis in both in vitro and in vivo bleeding models with low applied voltages, representing a new and novel class of hemostatic agents that are electrically-based.

Primary spontaneous pneumothorax in conjunction with Marfan syndrome.

A 25-year-old man with a history of Marfan syndrome, asthma and smoking presented with worsening dyspnoea and right-sided chest pain worsened with deep breathing after a fall 2 days prior. Diagnostic imaging revealed a spontaneous right-sided pneumothorax due to ruptured subpleural bullae in the apex of the right lung. Smaller subpleural bullae were also noted in the apex of the left lung. A chest tube was placed to reduce the right pneumothorax successfully.
