Successful treatment of vesicoureteral reflux by ureteroureterostomy in renal transplant recipients / 대한내과학회지

Recurrent urinary tract infection due to vesicoureteral reflux is one of the important medical complications in renal transplant recipients. Injection of macroplastique is recommended to reduce the vesicoureteral reflux, but it can result in poor responses. Ureteroureterostomy is an invasive method, but it is advisable in patients with higher grades of vesicoureteral reflux that do not respond to medical or macroplastique injection. We here report on two cases of successful treatment of vesicoureteral reflux by ureteroureterostomy. These patients experienced repeated episodes of acute pyelonephritis in spite of long-term antibiotic treatment and repeated macroplastique injection. No more urinary tract infection was observed after ureteroureterostomy. We recommend ureteroureterostomy in renal transplant recipients who suffer with repeated acute pyelonephritis due to vesicoureteral refulx.

Four cases of chloroma treated with hematopoietic stem cell transplantation / 대한내과학회지

Chloroma is an invasive extramedullary tumor composed of immature myeloid cells, which complicates the clinical course in a minority of patients with acute myeloid leukemia (AML). The presence of myeloid sarcoma is known to be a poor prognostic indicator in patients with AML. However, the optimal treatment of AML with concurrent chloroma has not been determined. We report four patients with AML accompanied by concurrent chloroma from the time of initial diagnosis. All of the patients underwent hematopoietic stem cell transplantation after complete remission. We also present a review of the literature.

A Case of Reversal of Takotsubo Cardiomyopathy in Patient with Pheochromocytoma

'Takotsubo cardiomyopathy' or 'stress-induced cardiomyopathy' is a newly described clinical entity characterized by transient left ventricular apical ballooning and left ventricular apical dyskinesis in the absence of angiographic feature of significant coronary artery disease. The cause of takotsubo cardiomyopathy is unclear, but catecholamines probably play a role in the takotsubo cardiomyopathy. We report a case of pheochromocytoma-induced takotsubo cardiomyopathy that showed atypical pattern of reversed takotsubo cardiomyopathy with transient significant mitral regurgitation. This is the first case showing the reversal of takotsubo cardiomyopathy due to pheochromocytoma in Korea.
