Pheochromocytoma and intestinal ganglioneuromatosis are rare entities, associated with Multiple Endocrine Neoplasia Type 2B (MEN2B), but rarely colonic pseudo-obstruction ischemia. We report a 52-year-old patient who presented perforation was later found to have all 3 pathologies concurrently. An exploratory laparotomy revealed toxic megacolon rectosigmoid requiring total abdominal colectomy. Diffuse no malignancy reported by histopathology. Perioperative challenges included severe acidosis...
Background Heart rate variability (HRV) is used to assess cardiac health and autonomic nervous system capabilities. With the growing popularity of commercially available wearable technologies, opportunity unobtrusively measure HRV via photoplethysmography (PPG) an attractive alternative electrocardiogram (ECG), which serves as gold standard. PPG measures blood flow within vasculature using color intensity. However, does not directly HRV; it pulse (PRV). Previous studies comparing...
