Hyperparathyroidism due to parathyroid cancer is rare. It is difficult to diagnose preoperatively but there should be an increased index of suspicion in those parathyroid Patient with palpable neck masses, profound hypercalcemia(greater than 14mg/dl), made increase of the parathyroid hormone level to greater than twice normal, and significant metabolic complications. In parathyroid cancer, systemic calcinosis is an extremely rare manifestation. The most common metastatic calcification site is lung and the other involved site is stomach, liver, skin and heart. After resection of parathyroid tumor, this systemic calcinosis is self-limiting. We experienced a patient with primary hyperparathyroidsm, presented with metastatic calcification in the lung and stomach disappeared by successful parathyroidectomy.

Abstract PDF: Many previously described nuclear medicine procedures to assess glomerular filtration rate have some problems because numerous blood sample is to be taken and they don't measure each separate renal function. Gates described isotopic method for the measurement of global and unilateral GFR based on the fractional renal uptake of (99m)Tc-DTPA 2 to 3 minutes after its intravenous injection. We evaluated GFR using (99m)Tc-DTPA in 57 people according to Gates method and compared with creatinine clearance. A good correlation was observed between creatinine clearance and GRF calculated by Gates' formula with an r value of 0.9(P<0.05). And also the relationship between parameters of (99m)Tc-DTPA renal scan images and GFR was taken. They were significantly correlated with GFR calculated by Gates' formula : r value 0.66 between relative intensity of peak renal to peak aortic activity(pK/pA) and GFR, -0.42 between time between aortic and kidney peak(A-K) and GFR and -0.48 between parenchymal renal activity at 25 min compared to peak kidney activity(25K/pK) and GRF. In conclusion, the determination of GFR according to Gates' formula shows good and reproducible of GRF with rapidity and simplicity. And the parameters from the renal scan images can use to estimate the renal function.

Abstract PDF: Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

Abstract PDF: The syndrome of inappropriate ADH secretion is a disorder characterized by hyponatremia which results from water retention attributable to ADH release. The hallmark of SIADH is hyponatremia due to water retention, in the presence of urinary osmolality above plasma osmolality. The SIADH was initially described by Schwartz et al (1957). This syndrome, first recognized in patients with bronchogenic carcinoma, has now been observed in a variety of other illnesses. Recently, we encountered a 59 year-old female with small cell lung cancer, also she had SIADH. Thus, we present a case and review the literature on the subject.

Correlation between Microalbuminuria Checked by RIA & Micral-Test®.: Chan Woo Lee, Kyu Chang Won, Soo Bong Choi; Yeungnam Univ J Med. 1991;8(2):158-163. Published online December 31, 1991; DOI: https://doi.org/10.12701/yujm.1991.8.2.158

Abstract PDF: It is evident that an elevation of airway albumin excreation rate without clinical proteinuria strongly predicts a later progression on diabetic renal disease. So we studied the correlation between Microalbumin checkly RIA & Micral-Test®. We collected urine between 08:00 h and 08:00 h next day and then checked microalbuminuria by radioimmunoassay method and Micral-Test® The results are as follows: 1. There was significant correlation between microalbuminuria checked by RIA & Micral-Test® 2. There was poor correlation between diabetes duration or HV-A1c and maximal change in albumin excreation rate. 3. So we concluded that Micral-Test® can be used in laboratory instead of RIA.
