A 64-year-old Asian man, with past medical history of hypertension, hypothyroidism, and hyperlipidemia, presented with 3 days history of fever associated with cough and worsening shortness of breath. Subsequent clinical course was complicated by acute lung injury leading to acute respiratory distress syndrome requiring positive pressure ventilation, septic shock requiring inotropic support, and acute kidney injury requiring continuous renal replacement therapy (CRRT). On day 3 of CRRT, the patient developed significant hypothermia (temporal temperature 27.58C), which was successfully managed. Continuous renal replacement therapy was subsequently discontinued as renal function recovered and the patient was discharged home after a prolonged hospital stay. He currently remains off dialysis and is being followed as an outpatient for chronic kidney disease. In this article, we examine various aspects of pathophysiology and management of hypothermia on CRRT and review relevant literature in this field.

Hypertension and proteinuria in pregnant women are most commonly signs of preeclampsia which develops after 20 weeks of gestation. There are rare incidences of uncontrolled hypertension and nephrotic range proteinuria even in the first trimester of pregnancy which can be indicators of severe underlying fetal and placental abnormalities rather than preeclampsia. A G2P0 30-year-old Caucasian woman was admitted to University Hospital for the incidental finding of severe hypertension and proteinuria during her regular prenatal checkup at 14 weeks. She had complaints of mild bifrontal headache, facial and lower extremity edema. Her admission blood pressure was 193/108 mmHg, she had 8 g proteinuria, normal creatinine, and negative immunological and infectious workup. Further evaluation with dedicated obstetric ultrasonography showed hydropic placenta and fetus with aneuploidy. These findings strengthened the suspicion for a rare disease process called mirror syndrome, and emergent delivery was done to treat maternal disease process. Mirror syndrome is a rare disease that occurs basically due to fetal/placental pathology. It can present at any gestational period, and the clinical features include edema, proteinuria, and hypertension, mimicking preeclampsia. Prompt diagnosis and treatment is very crucial to prevent maternal complications.
