Diabetes mellitus, obstructive uropathy and urinary infection were considered to be most important in the etiology of renal papillary necrosis in the past literature. However, since 1953, Spuhler and Zollinger reported an association between phenacetin abuse and renal papillary necrosis, the most frequent cause of renal papillary necrosis has been diabetes mellitus, while analgesic abuse (contained phenacetin) has been the second most common factor in recent reports. In the more recent literature, most of the patient have had neither obstructive uropathy nor urinary infection, and it is quite possible that there two condition are of no direct etiological significance. But in this case, we can not suggest definite etiological factor except urinary infection clinically. Only one case is reported showing clinical manifestations laboratory findings, pyelographic findings and pathological changes compare with previous papers.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

BACKGROUND: Circardian variation in the onset of cardiovascular events includig sudden cardiac death, myocardial infarction and ventricular arrhythmias has been discribed. The frequency of ventricular premature complexes has also been reported to demonstrate a pattern consisting of a daytime peak and nightime nadir. We tried to see if the same circardian pattern is found in dilated cardiomyopathy patients. We have also studed how various modifying factors such as left ventricular ejection fration and ACE inhibitor use may affect the circardian pattern. METHOD: 24-hour ambulatory electrocaridiographic monitorings were performed in 50 dilated cardiomyopathy patients and 20 control subjects. Patients were prospectively divided in 2 groups based on LVEF and ACE inhibitor use. RESULTS: In dilated cardiomyopathy patients, the expected morning increase in VPC frequency is absent and show a peak in evening. This pattern is not correlated with heart rate. Evening peak is more prominent in low LVEF group and ACE inhibitor non-user group. CONCLUSION: In dilated cardiomyopathy patients, VPC frequency show a peak in the evening.

Aortic root diameter by two dimensional and M-mode echocardiography in predicting prosthetic aortic valve size preoperatively was measured in 10 adult patients undergoing aortic valve replacement. Correlation of aortic root diameter measured by two dimensional echocardiography and actual prosthetic valve size implanted by aortic valve replacement was excellent. Correlation coefficient was statistically significant (r=0.91, P<0.001). Correlation of aortic root diameter measured by M-mode echocardiography and actual prosthetic valve size was also excellent. Correlation coefficient was statistically significant (r=0.86, P<0.001). This study demonstrates that aortic root diameter by two dimensional and M-mode echocardiography can accurately predict prosthetic aortic valve size in patient undergoing aortic valve replacement.

OBJECTIVE : To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in recurrent spontaneous abortion associated with hyperhomocysteinemia. MATERIAL AND METHOD: The blood Sample of habitual aborter with high fasting homocysteine level was tested by PCR-RFLP method. RESULTS: The patient was found to be a homozygosity for MTHFR gene mutation that was confirmed by the finding which is consistent with the mutation at the nucleotide 677 C to T, Corresponding to Ala to Val. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the MTHFR mutation should be examined in the workup of recurrent spontaneous abortion showing hyperhomocysteinemia.

It is generally accepted that in acute pancreatitis, the enzymes normally excreted by the pancreas are released from the disrupted parenchyma into the extraductal space and taken up by way of the lymphatics and capillaries. The enzymes in the blood stream may appear in high concentration in the serum. Therefore, serum amylase and lipase determinations has long been a mainstay in the diagnosis of acute pancreatitis and other pancreatic diseases. However, many investigators have claimed that the urinary output of amylase may be elevated more consistently in acute pancreatitis than in the serum concentration of either amylase or lipase, and urinary amylase measurement is a more sensitive reflection of the presence of pancreatitis and of its clinical course than is the measurement of serum amylase or lipase. Clinically, one of the ominous signs which may develop during the early course of acute pancreatitis is severe hypotension. But, no agreement has been reached among investigators as to the cause of the hypotension, although several investigators have implicated a blood volume deficiency resulting form inflammatory process, and hypercalcemia. Perhaps, the majority have attributed the hypotension to systemic effect of some of the pancreatic enzymes, especially trypsin. Nevertheless, the correction of these factors sometimes fail to restore a normal blood pressure clinically. The purpose of the present investigation was to observe the relationships between serum concentration and urinary output of pancreatic enzymes, and to determine the degree of hypotension resulting from the systemic administration of pancreatic enzymes. These experimental procedures, consisted of heteroinfusion of human pancreatic juice and homoinfusion of canine pancreatic emulsion intravenously, and pancreatic ductal ligation in dogs. Blood and urine samples for the enzyme analysis were collected serially thorough the femoral vein and ureteral catheter before and after the procedure. Blood pressure was measured consistently by the kymograph before and after infusion of pancreatic juice. Activities of amylase and lipase were determined by methods of Nelson and, Cherry and Crandall, respectively. The results obtained are summarized as follows; 1. Following intravenous infusions of pancreatic juice exogenously. serum and urine concentrations of amylase and lipase increased rapidly, but these enzymes decreased rapidly in urinary excretion and gradually in serum concentration. Urinary recovery of amylase was approximately 10% of the total infused amount of pancreatic juice at the end of 4 hours. 2. Following ligation of the pancreatic duct, the amylase and lipase levels of serum rose gradually and reached the maximum at 24-48 hours after ligation and then gradually fell. The output of these enzymes in the urine were relatively constant while serum enzymes were increased. 3. When the human pancreatic juice was infused, hypotension was pronounced, and it was deeper and more prolonged in hypotensive effect with infusion of highly concentrated juice in the enzyme activities. With human pancreatic juice, a more sustained hypotension occurred than was observed after infusion of canine pancreatic emulsion. As a result of this investigation, it is felt that the hypotension in acute pancreatitis is probably the result of pancreatic enzymes itself. 4. In postinfusion period, the urine volume was markedly decreased following hypotension, and the urine volume was increased following blood pressure to normal level. This suggests that urine volume may diminish resulting from transient acute renal failure due to hypotensive effect by pancreatic enzymes.
