BACKGROUND/AIMS: Primary thyroid disease is prevalent in chronic renal disease, especially in patients requiring chronic dialysis. However, the relationship between kidney function and the prevalence of primary thyroid disease has not been studied in Korea, a nation where the dietary iodine intake is excessive. METHODS: Retrospective data from 2201 consecutive adult patients who visited a health promotion center over the last 5 years were analyzed; specifically, 54 patients with chronic kidney disease not requiring hemodialysis and 64 adults treated with hemodialysis. The glomerular filtration rate (GFR) was estimated using the abbreviated Modification of Diet in Renal Disease equation. Multivariable logistic regression was used to evaluate the independent association between the prevalence of primary hypothyroidism and estimated GFR. RESULTS: The prevalence of overt hypothyroidism increased from 0.5% at an estimated GFR > 90 mL/min/1.73 m2 to 6.3% in end-stage renal disease requiring chronic dialysis (p < 0.001 for trend). Compared with participants with an estimated GFR > 60 mL/min/1.73 m2, those with an estimated GFR < 60 mL/min per 1.73 m2 had an increased odds of overt hypothyroidism after adjusting for age, gender, fasting blood glucose (FBS), and the total cholesterol (TC) and triglyceride (TG) concentrations. CONCLUSIONS: These findings suggest that overt primary hypothyroidism is relatively common (6.3%) among persons with chronic kidney disease requiring chronic dialysis, and it is independently associated with a progressively lower estimated GFR.

BACKGROUND: Cardiac computed tomography (CT) has emerged as an alternative to magnetic resonance imaging (MRI) for ventricular volumetry. However, the clinical use of cardiac CT requires external validation. METHODS: Both cardiac CT and MRI were performed prior to pulmonary valve implantation (PVI) in 11 patients (median age, 19 years) who had undergone total correction of tetralogy of Fallot during infancy. The simplified contouring method (MRI) and semiautomatic 3-dimensional region-growing method (CT) were used to measure ventricular volumes. RESULTS: All volumetric indices measured by CT and MRI generally correlated well with each other, except for the left ventricular end-systolic volume index (LV-ESVI), which showed the following correlations with the other indices: the right ventricular end-diastolic volume index (RV-EDVI) (r=0.88, p<0.001), the right ventricular end-systolic volume index (RV-ESVI) (r=0.84, p=0.001), the left ventricular end-diastolic volume index (LV-EDVI) (r=0.90, p=0.001), and the LV-ESVI (r=0.55, p=0.079). While the EDVIs measured by CT were significantly larger than those measured by MRI (median RV-EDVI: 197 mL/m² vs. 175 mL/m², p=0.008; median LV-EDVI: 94 mL/m² vs. 92 mL/m², p=0.026), no significant differences were found for the RV-ESVI or LV-ESVI. CONCLUSION: The EDVIs measured by cardiac CT were greater than those measured by MRI, whereas the ESVIs measured by CT and MRI were comparable. The volumetric characteristics of these 2 diagnostic modalities should be taken into account when indications for late PVI after tetralogy of Fallot repair are assessed.

Congenital adrenal hyperplasia (CAH) during pregnancy is a rare condition. Only a few cases have been reported in the literature. CAH patients has lower pregnancy rate compared to normal women. A 27-year-old nulliparous woman, a diagnosed case of 21-hydroxylase deficient simple virilising form of classic CAH visited. She got pregnant spontaneously without any trial of assisted reproductive technology. At the age of 12, she underwent clitoral resection and vaginoplasty. She took dexamethasone or prednisolone after operation. She delivered healthy singleton female baby by cesarean section. Four years later, she delivered healthy singleton female baby by repeat cesarean section. Two female babies have shown normal external genitalia. Here, we report a case of successful pregnancy and delivery in a patient with CAH.

A multistage plan and multidisciplinary approach are the keys to successful repair in patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCAs). In this article, we present a multidisciplinary approach adopted to treat a patient with PA with VSD and MAPCAs associated with left pulmonary artery interruption.
