Recurrent Brain Metastasis Versus Radiation-Induced Necrosis: A Case Report and Literature Review.

Radiotherapy is the cornerstone of brain metastasis management. With the advancement of therapies, patients are living longer, exposing them to the long-term effects of radiotherapy. Using concurrent or sequential chemotherapy, targeted agents, and immune checkpoint inhibitors may increase the incidence and severity of radiation-induced toxicity.

Asymptomatic benzocaine spray-induced methaemoglobinaemia in preoperative sedation for oesophagogastroduodenoscopy.

Methaemoglobinaemia is defined as elevated methaemoglobin in the blood which is characterised by conversion of some of the reduced ferrous iron elements [Fe2+] to the oxidised ferric [Fe3+] form which does not have capacity to bind and transport oxygen resulting in functional anaemia. Causes can be genetic mutations or acquired by medications such as dapsone, nitrates or benzocaine. Benzocaine is currently being used as a topical anaesthetic agent before certain procedures.

Left Ventricular Thrombus Formation in a Structurally and Functionally Normal Heart: A Case Report and Literature Review.

Left ventricular (LV) thrombosis usually occurs as a complication of acute anterior myocardial infarction (MI) and dilated cardiomyopathy. It also occurs in patients with a hypercoagulable state. However, in the setting of normal systolic function, LV thrombi are extremely rare.

Extracorporeal Membrane Oxygenation (ECMO): A Life Saver in Near-Fatal Asthma.

Near-fatal asthma (NFA) is a life-threatening condition that represents the most severe clinical phenotype of asthma and can progress to fatal asthma. Patients with NFA do not respond adequately to conventional medical therapy and urgent intervention is needed to provide adequate oxygenation by invasive mechanical ventilation. While mechanical ventilation is a potentially life-saving intervention, it could cause lung injury, barotrauma, and dynamic hyperinflation due to high ventilator settings resulting in hemodynamic instability.

A Paraneoplastic Leukemoid Reaction in Primary Lung Sarcoma.

Pulmonary malignancies are known to have high prevalence and mortality. They are associated with different paraneoplastic syndromes, especially pulmonary carcinomas, because they are more common than pulmonary sarcomas. We present a case of a 56-year-old African American male who was admitted to our institution with a three-month history of a dry cough, progressive shortness of breath, and two to three days of right arm swelling.

Emphysematous endometritis in stage III endometrial cancer.

We report a case of emphysematous endometritis in a 65-year-old patient who has stage III, high-grade, poorly differentiated endometrial cancer; she was on chemotherapy. The patient developed pyogenic emphysematous endometritis complicated by hypovolemic shock and sepsis. She was admitted to the intensive care unit for treatment with vasopressors and antibiotics.

Recurrent Spontaneous Pneumothorax Associated With Marijuana Abuse: Case Report and Literature Review.

Marijuana is the most commonly used illicit recreational drug in the United States. Growing public support for marijuana law reform has resulted in a significant increase in its use. The harmful pulmonary consequences of chronic marijuana smoking are less researched and discussed than those of tobacco smoking.
