Although sarcoidosis is an established cause of multiorgan dysfunction, acute presentation with thrombotic microangiopathy resulting in severe renal and hematological sequelae has not been reported. We describe the case of a patient presenting with hypercalcemia, pancreatitis, and acute renal failure, followed by microangiopathic hemolytic anemia. ⋯ Corticosteroids were commenced with clinical and biochemical improvement. This novel case highlights the need to consider sarcoidosis as part of the differential diagnosis for unusual multiorgan presentations and for early multidisciplinary involvement in such cases to permit optimal treatment.

Ambient air pollution may affect the severity of untreated OSA, but it is unknown whether air pollution adversely impacts the effectiveness of positive airway pressure (PAP) therapy. ⋯ We demonstrated a modest but statistically significant increase in residual respiratory events during PAP therapy associated with an increase in air pollution concentrations.

A 13-year-old male patient with intermittent asthma and joint hypermobility presented to the ED in acute hypoxemic respiratory distress. He reported experiencing cough, increased work of breathing, and worsening chest pain for 3 days before presentation. He also reported fatigue and decreased appetite for 2 weeks. ⋯ His lifestyle was described as sedentary; he did not play any sports or have any unusual hobbies. He did not take any daily medications and no environmental exposures were reported. There was no family history of pulmonary, autoimmune, or connective tissue disease.

A 17-year-old girl received lung transplantation after chronic respiratory failure. She developed a fever (> 38 °C) once or twice weekly starting 2 months after surgery, and multiple papulopustules on the skin waxed and waned for 4 months. She then developed blood-tinged sputum. She had been treated with triple immunosuppressants, including prednisolone, tacrolimus, and mycophenolate mofetil after lung transplantation, and her symptoms appeared during prednisolone dose reduction.
