Mitral Valve Replacement with a Pulmonary Autograft in an Infant

A 76-day-old infant weighing 3.4 kg was referred for surgical intervention for severe mitral valve stenoinsufficiency caused by leaflet fibrosis and calcification. He had experienced a cerebral infarction in the left middle cerebral artery territory, which was deemed attributable to an embolism of a calcified particle from the dysmorphic mitral valve. Because mitral valve replacement using a prosthetic valve was not feasible in this small baby, mitral valve replacement with a pulmonary autograft was performed. After a brief period of extracorporeal membrane oxygenation (ECMO) support, he was weaned from ECMO and was discharged home without further cardiovascular complications.

Clinical Outcomes of Lung Transplantation: Experience at Asan Medical Center

BACKGROUND@#Lung transplantation is a life-saving procedure in patients with end-stage lung disease, and is increasingly performed in Korea.@*METHODS@#We retrospectively evaluated the outcomes of patients who received a lung transplant at Asan Medical Center between January 2008 and December 2016. Thirteen of 54 patients experienced multiorgan transplantation; the remaining 41 who received only lung grafts were included.@*RESULTS@#The mean age of the lung transplant recipients was 44.6 years; 27 were men and 14 were women. The most frequent reasons were idiopathic interstitial pneumonia (21 of 41 patients, 51.2%), interstitial lung disease (9 of 41, 22.0%), and bronchiolitis obliterans after bone marrow transplantation (7 of 41, 17.1%). The median waiting time was 47 days, and many patients received preoperative intensive care (27 of 41, 65.9%), ventilator support (26 of 41, 63.4%), or extracorporeal life support (19 of 41, 46.3%). All 41 patients received bilateral lung grafts. Ten deaths occurred (24.3%), including 5 cases of early mortality (12.2%) and 5 cases of late mortality (12.2%). The 1-, 3-, and 5-year survival rates were 78.9%, 74.2%, and 69.3%, respectively.@*CONCLUSION@#Despite a high percentage of patients who required preoperative intensive care, the transplantation outcomes were acceptable.

A Case of Pseudovaginal Perineoscrotal Hypospadias with 5alpha-reductase Deficiency / 대한비뇨기과학회지

Male pseudohermaphroditism can be caused by absent m llerian regression, inadequate synthesis of testosterone, inadequate synthesis of dihydrotestosterone, or androgen receptor deficiency. Defects in either the production or the action of androgenic steroids have been demonstrated to cause pseudovaginal perineoscrotal hypospadias, a syndrome of male pseudohermaphroditism. This is mostly caused by a deficiency of 5alpha-reductase, which controls the conversion of testosterone to 5alpha-dihydrotestosterone. We report a case of male pseudohermaphroditism due to 5alpha-reductase deficiency who was born with ambiguous genitalia and was reared as female.
