It is important to maintain normal calcium concentration especially ionized calcium concentration in chronic renal failure patients on hemodialysis. The direct measurement of ionized calcium is less commonly used due to a lack of automated equipment as well as the cost of laboratory equipment. Numerous formulas for adjusted total calcium and calculated ionized calcium are used in clinical practice. We examined the relationship between direct measured ionized calcium and total calcium, corrected total calcium, calculated ionized calcium (formula of Nordin et al) in 53 chronic renal failure patients on hemodialysis. The results were as follows; 1) In predialysis group, plasma total and ionized calcium levels were 2.36+/-0.26, 1.04+/-0.21mmol/L respectively, and higher than normal controls. The correlations between plasma ionized calcium and total calcium, calculated ionized calcium, corrected total calcium were r=0.72 (P=0.0001), r=0.81 (P=0.0001), r=0.65 (P=0.0001) respectively. The plasma ionized calcium level was not correlated with the level of albumin, pH, phosphate, parathyroid hormone. 2) The plasma total and ionized calcium levels were significantly increased with hemodialysis and values were 2.49+/-0.14mmol, 1.14+/-0.14mmol/L respectively. The correlation between ionized and total calcium was r=0.41 (P=0.0021). These results suggested that the calculated ionized calcium (formula of Nordin et al) and total calcium can be used to predict the plasma ionized calcium level in chronic renal patients on hemodialysis.

BACKGROUND: Though immunotherapy(IT) has become an effective rnethod in extrinsic allergic patients who didn't respond to pharmacologic therapy or couldn't avoid allergen, the mechanism, termination index and prognostic index of IT have not been clarified yet. METHOD: We selected 81 asthmatic children on immunotherapy with house dust mite (Dermatophagoides pteronyssinus and Dermatophagoides farinae). We measured the hematologic findings, the levels of serum IgG and IgE, allergen(house dust, Dermatophagoides pteronyssinus and Dermatophagoides farinae)-specific IgE concentrations, lymphocyte subsets and methacholine challenge test yearly during IT, and checked the radiographs of chest and paranasal sinus. RESULTS: Peripheral white blood cell count, the percentage of eosinophil and total eosinophil count decreased significantly after 2 years of IT. Serum IgG level increased significantly after 3 years of IT. Serum total and specific IgE levels decreased significantly after 3 years of IT, but they were still higher than the normal values. CD4+, CD8+, and B lymphocytes did not change with the IT, but CD3+ lymphocytes increased significantly after 2 years of IT. PC20-methacholine increased significantly after 1 year of IT, but no correlation was found between the duration of IT and bronchial hyperreactivity. Twenty-eight patients(34.6%) had abnormal findings on chest radiographs: 15 patients(53.6%) as bronchitis, 10 patients(35.7%) as bronchopneumonia, 2 patients(7.1%) as hyperinflation and 1 patient(3.6%) as atelectasis. Sixty-three patients(77.8%) had abnormal findings on paranasal sinus radiographs. In the follow-up radiographs of 49 patients, 28 patients(57.1%) showed improvement of paranasal sinusitis after 1 year of IT. CONCLUSION: This study showed some changes of the immunologic findings such as eosinophil count, IgG, IgE, allergen-specific IgE and CD3+ lymphocytes, and improvement of bronchial hyperreactivity and paranasal sinusitis' in asthmatic children during IT. These findings were closely related to clinical improvement.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

OBJECTIVES: Subacute thyroiditis is a nonsuppurative inflammation of thyroid gland and is probably caused by a cytopathic virus. Typical clinical symptoms and features of subacute thyroiditis vary widely during the course of illness. It has a clinical course, evolving from hyperthyroidism through a temporary hypothyroidism to recovery. However, the final outcome of this disease remains unpredictive in some patients. Permanet hypothyroidism occurs infrequently. METHODS: Thirty-three patients proven to have subacute thyroiditis at the Ewha Womans University Hospital from September 1993 to November 1995 were studied. We analyzed their clinical features, laboratory findings, and duration of recovery to cha- racterize the course of the disease. RESULTS: 1) Total 33 patients were studied: 31 patients were female and 2 patients were male. Their mean age was 42.6+/-8.3 years old. The peak months were August through October in this study. 2) Initial mean ESR was 73.0+/-35.2mm/hr, mean T3 was 217.3+/-73.9ng/dl, mean T4 was 15.2+/-8.5microgram/ dl, and TSH was 0.06+/-0.09microIU/ml. The positive rates of antithyroglobulin and anitmicrosomal antibodies were 31% and 6% respectively, and TSH receptor antibody was elevated in one patient. 3) In the thyroid scan, 91% showed both lobes nonvisualisation, and 9% showed one lobe nonvisualization. Radioactive iodine uptake(RAIU) at 24 hour was 2.4+/-3.3%. 4) With the predisolone therapy, 90% of patients completely recovered, 57% of these patients had no hypothyroid phase and remaining 33% of them had hypothyroid phase during course of the disease. Three of the patients had permanent hypothyroidim. 5) The average duration of recovery was 3.2+/-1.4 months and it has no correlation with initial thyroid hormone levels, antithyroid antibodies and duration of steroid administration. CONCLUSION: There was no historical, physical, laboratory findings that help us predict those patients likely to have an exacerbation of the disease.
