- Primary aldosteronism is a syndrome characterized by various clinical features that are due to excessive autonomous aldosterone secretion not sustained by the activation of the renin-angiotensin system. Aldosterone-producing adrenal adenoma is found in approximately 35% of the patients who suffer with primary aldosteronism. Laparoscopic adrenalectomy is the standard treatment for aldosterone-producing adrenal adenoma, and the result of this operation is normalization of the serum potassium and plasma aldosterone concentrations, as well as correcting the plasma renin activity in most cases. However, it is known that some of the patients with aldosterone-producing adrenal adenoma show transient hyperkalemia postoperatively due to the reversible suppression of the renin-aldosterone axis. We recently experienced the case of a 54-year-old woman with an aldosterone-producing adrenal adenoma, and she presented with severe hyperkalemia after unilateral adrenalectomy. Compared with the previously reported cases that showed transient suppression of the rennin-aldosterone axis for less than 7 months, our patient revealed a prolonged episode of hyperkalemia for 8 months postoperatively, and this required continuous mineralocorticoid replacement.

- A functioning paraganglioma is a rare catecholamine-producing tumor that arises from the extra-adrenal chromaffin tissue. Recently we experienced a case in which a 42 year-old male patient with a functioning extra-adrenal paraganglioma mimicked an acute coronary syndrome. A functioning extra-adrenal paraganglioma was diagnosed by means of a biochemical study and a radiological imaging study. After stabilizing his blood pressure, using alpha adrenergic blocker, we successfully removed a 6?cm sized paraganglioma from between the aorta and the IVC in the retroperitoneal space.

- BACKGROUND
Bone mineral density(BMD) is thought to be under genetic control. Polymorphisms at the vitamin D receptor(VDR) gene have recently been shown to contribute to the genetic variability in bone mineral density in Caucasians. However, the relationship between VDR-RFLP(restriction fragment length polymorphisms) and bone mineral density is controversial. METHODS: The VDR-RFLP by BsmI, ApaI, and TaqI were studied in 250(77 premenopausal, 173 postmenopausal) Korean women. Bone mineral densities at the lumbar spine(L2-L4), femoral neck, greater trochanter, and Wards triangle were measured by DEXA(Dual Energy X-ray Absorptiometry; Lunar DPX-L, U.S.A.). RESULTS: There were significant differences in VDR gene allele frequency when compared with those in Caucasians. The BsmI polymorphism was consisted of 0.8% BB homozygotes, 12.4% Bb heterozygotes, and 86.8% bb homozygotes. The ApaI polymorphism was 6.8% AA homozygotes, 42.0% Aa heterozygotes, and 51.2% aa homozygotes, and the TaqI polymorphism was 83.2% TT homozygotes, 16.8% Tt heterozygotes, and 0% tt homozygotes. When these three VDR-RFLP were combined, bbaaTT(51.2%), bbAaTT(29.6%), and BbAaTt(10.0%) were found to be most frequent types. There were no significant relationship between VDR-RFLP and BMD measured at the 2nd to 4th lumbar spine in all subjects. But there were significant relationship between VDR-RFLP and BMD at the proxmial femur in all subjects. Compared with bb or bbaaTT(or bbAaTT), women with the Bb or BbAaTt genotypes had significantly lower bone mineral densities at the proximal femur in all subjects. When we restricted the analysis to early postmenopausal women less than 10 years since menopause, these findings were more pronounced. CONCLUSION: These results suggest that VDR-RFLP may affect on BMD at the proximal femur in Korean women. However, the frequencies of B, A, and t alleles are very low in Korean women compared to those of Caucasians, further studies will be needed, with larger sample sizes.
