RESUMEN
Acquired tracheoesophageal fistula (TEF) is a rare complication of esophageal or lung cancer. A 57-year-old male presented with complaints of vomiting, cough, 20 lb weight loss, and progressive dysphagia. Early laryngoscopy and CT chest showed a normal pharynx with an irregular thickness of the thoracic esophagus. The upper gastrointestinal endoscopy (UGIE) and upper endoscopic ultrasound (EUS) revealed a hypoechoic mass evolving as complete obstruction. During the procedure, minimal CO2 was used for insufflation; however, when attempts were made to traverse the obstruction, capnography revealed an end-tidal CO2 (EtCO2) estimating 90 mmHg indicating possible TEF. This case depicts the use of capnography during UGIE in diagnosing an acquired TEF.
RESUMEN
Tuberculosis, while rare, is a disease that can have several extrapulmonary manifestations. One such known extrapulmonary manifestation of disseminated TB is vertebral osteomyelitis, often referred to as "Pott's Disease." We present the case of a patient who underwent back surgery with allogenic bone graft who developed vertebral osteomyelitis and subsequently had disseminated tuberculosis, from an infected bone graft. We review current guidelines for allograft tissue screening and discuss the possible need for standardizing tuberculosis screening for bone allografts.
RESUMEN
Immune thrombocytopenic purpura is a disorder characterized by decreased platelet count that may be secondary to infectious or autoimmune etiologies. We present a patient with upper gastrointestinal bleeding complicated by severe thrombocytopenia. Endoscopy revealed gastritis with pathology positive for Helicobacter pylori. Platelet count normalized after triple antibiotic therapy. The precise mechanism by which H. pylori causes immune thrombocytopenic purpura remains unclear; however, there are several plausible mechanisms. This case highlights the importance of keeping H. pylori in the differential in patients presenting with thrombocytopenia.
