Background/Aims: The occurrence of gout attacks at the start of uric acid lowering treatment worsens compliance. We aimed to determine the appropriate dose of febuxostat to reduce the occurrence of gout attacks during the initial treatment period. Methods: We retrospectively analyzed the data of patients diagnosed with gout who underwent treatment at Jeju National University Hospital between May 2018 and May 2020. Results: Two-hundred and twenty-seven patients were included, with a mean age of 53.2 ± 16.4 years, and 219 (96.5%) were male. The patients were divided into two groups according to the starting dose of febuxostat (20 mg vs. 40 mg). There were no significant differences in mean age, disease duration, colchicine, estimated glomerular filtration rate (eGFR), initial uric acid levels, and presence of subcutaneous tophi between the two groups. Gout attacks occurred more frequently in the 20 mg group than in the 40 mg group during the first 3 months of treatment (32.0% vs. 14.3%, p = 0.002), particularly during the first month (21.3% vs. 7.5%, p = 0.005). Multivariate logistic regression analysis was conducted adjusting for the effects of disease duration, the presence of subcutaneous tophi, eGFR, and initial uric acid levels. A febuxostat starting dose of 40 mg (odds ratio, 0.464; 95% confidence interval [CI], 0.246 to 0.862; p = 0.015) and anti-inflammatory prophylaxis (odds ratio, 0.359; 95% CI, 0.158 to 0.813; p = 0.014) were found to be independent factors associated with a gout attack. Conclusions Starting uric acid lowering treatment with febuxostat 40 mg rather than 20 mg may reduce the incidence of gout attacks in the early period of treatment in Korean patients with gout.

Accelerated atherosclerosis is not only a frequent complication but also the most common cause of death in patients with chronic renal failure (CRF). Although mechanisms are unclear, disorder of lipid metabolism may be a major factor. Since apolipo-protein (apo) E is known to play a major regulatory role in lipid metabolism, we evaluated apo E genotype in 72 male patients with CRF and compared with that in 194 rnale normal controls. In addition, we measured plasma lipid and apolipoprotein concentrations and evaluated them according to apo E genotype in patients and controls. Apo E genotype was determined with the INNO-LiPA Apo E kit (Innogenetics, Belgium), which is based on reverse hybridization. The results are as follows ; 1) The distribution of the three major apo E alleles in patients with CRF ( e 2: 6.2%, e 3: 80.6%, e 4: 13.2%) was not different from that in controls ( e 2: 4.1%, e 3: 87.6%, e 4: 8.3%). 2) In patients with CRF, total cholesterol, lowdensity lipoprotein (LDL) and high-density lipoprotein (HDL) levels were significantly lower and the triglyceride and lipoprotein (a) levels were significantly higher than those in controls. 3) In controls, E 4/3 group had significantly lower levels of HDL than E 3/3 and E 3/2 groups. In patients with CRF, E 4/3 group had significantly higher levels of total cholesterol and apo B lipoprotein than E3/2 group. In conclusion, although there was no significant difference in the apo E genotype frequencies between male patients with CRF and controls, apo E polymorphism may play an important role in the determination of individual differences in plasma lipids in male patients with CRF.

PURPOSE: The use of thyroidectomy has increased as a diagnostic technique for thyroid disease. However, performance of a, thyroidectomy is accompanied with complications. Post-thyroidectomy complications include recurrent laryngeal nerve palsy, hypocalcemia, hematoma, infection, and thyroid storm. The aim of this study was to determine the clinical incidence and to evaluate complications after a thyroidectomy, including recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and scaring, following a retrospective review of cases. METHODS: From July 2004 to May 2006, 661 consecutive patients that had undergone a thyroidectomy were identified. Through a retrospective review, we evaluated the incidence and type of complications, including recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and postoperative scaring. RESULTS: 1) Recurrent laryngeal nerve palsy was a very serious complication, but had a very low incidence. Eight cases out of 661 cases developed and most of the cases developed after a total thyroidectomy. 2) Hypocalcemia was the most common complication. Each incidence of hypocalcemia of methods of thyroid surgery was significant (P= 0.019) but, thyroid disease did not have significant difference (P=0.071). 3) The incidence of postoperative hematoma was 2.74% (18/655). Graves’ disease was more predominant than other diseases. CONCLUSION: Post-thyroidectomy complications and cosmetic problems include recurrent laryngeal nerve palsy, hypocalcemia, hematoma, and postoperative scar. An understanding of the incidence and review of complications after a thyroidectomy may reduce their incidence.

Milwaukee shoulder syndrome (MSS) is a rare disease in which joints are destroyed and occurs mainly in elderly women. We describe rapidly progressive MSS with complete destruction of the shoulder joint within 2 months. An 80-year-old woman visited the outpatient clinic with shoulder pain for 2 weeks. rotator cuff tear arthropathy was diagnosed, and nonsteroidal anti-inflammatory drugs were prescribed. Two months later, her shoulder pain worsened without trauma. Shoulder swelling and tenderness, and arm lifting inability were observed. Complete humeral head disruption was observed by radiography. We diagnosed MSS based on the presence of serohematic and noninflammatory joint effusion, periarticular calcific deposits, and rapid joint destruction, and initiated conservative treatment. When initially treating elderly patients with shoulder arthropathy, it is advisable to perform short-term follow-up and to consider the possibility of crystal-induced arthropathy.

Diarrea-associated hemolytic uremic syndrome (HUS) is very rare in adults. Few reports are available on clinical features and plasma exchange in adult patients with diarrhea-associated HUS in Korea. We retrospectively examined the records of five adult patients with diarrhea-associated HUS admitted to Samsung Seoul Hospital between January 1995 and December 1997. If the patient had neurologic abnormalities, or there was rapid clinical deterioration, with the hematocrit decreasing below 20%, the platelet count falling below 10,000/mm3, the creatinine concentration increasing above 5.0 mg/dl, plasma exchange was begun. There were 4 females and 1 male. Patients ranged in age from 16 to 61 years. All patients presented with diarrhea and abdominal pain, and 3 patients had bloody diarrhea. The mean time between the onset of diarrhea and thrombocytopenia was 4.4+/-1.9 days (range, 1 to 6). All patients received 7 to 24 plasma exchanges. The mean exchanged plasma volume was 1.1+/-0.2 times of patients own plasma volume. The pattern of clinical response to plasma exchange was initial normalization of platelet count (8.0+/-3.8 days), followed by normalization of LDH level (20.2+/-14.5 days) and creatinine concentration (25.8+/-13.8 days). Metabolic alkalosis developed in two patients undergoing daily plasma exchange. We successfully managed the metabolic alkalosis with continuous venovenous hemofiltration. The mean duration of hospitalization was 28.8+/-11.2days (range, 20 to 42). All patients successfully recovered without any sequale. Although this study is based on small case series, we suggested that plasma exchange may improve the outcome in adult diarrhea-associated HUS.

The simultaneous occurrence of primary glomerulonephritis in identical twins has been rarely reported previously. It has suggested that genetic factors may play an important role in the pathogenesis of primary glomerulonephritis. We describe a pair of 17-year-old identical twin brothers with asymptomatic proteinuria, one with histologically proven minimal change disease and the other with focal segmental glomerulosclerosis. HLA typing in twin brothers revealed an identical phenotype consisting of A25, A33, B44, B54, Cwl, Cw7, DR7 and DRB1. To our knowledge, this is the first case of glomerulonephritis in identical twins in Korea.

BACKGROUND: The urinary protein to creatinine ratio in a single voided random urine sample has been widely used as an estimation of 24 hour urine protein excretion because of inconvenience and frequent collection errors during timed collection of 24 hour urine. But the protein to creatinine ratio also showed frequent estimating error, overestimation or underestimation. We thought that protein to creatinine ratio adjusted by daily creatinine excretion estimated by Cockroft-Gault equation can be more accurate than protein to creatinine ratio and compared them as follows. METHODS: This study consisted of 81 patients whose 24 hour urine protein excretion and random spot urine protein to creatinine ratio were measured concomitantly. There was no significant change of body weight or serum creatinine change around the study day. The modified protein to creatinine ratio could be estimated from the measured protein to creatinine ratio in a random spot urine sample by multiplying the ratio by the expected daily creatinine excretion estimated by Cockroft-Gault equation. These results were compared with well collected 24 hour urine protein. RESULTS: The difference between protein to creatinine ratio and 24 hour urine protein was 0.87+/-1.13, on the other hand, the difference between modified protein to creatinine ratio and 24 hour urine protein was 0.52+/-0.65 (p<0.05). Correlation coefficients between protein to creatinine ratio, modified protein to creatinine ratio and 24 hour urine protein were 0.877, 0.957 respectively. CONCLUSION: The protein to creatinine ratio modified by the expected daily creatinine excreation rate calculated by Cockfort-Gault equation was more accurate than simple protein to creatinine ratio.

We evaluated gastric emptying time (GET) by using Tc99m-sulfur colloid gastric emptying scintigraphy in 11 patients with CAPD (6 male, 5 female) and 14 healthy volunteers. We investigated the effect of dialysate dwelling on GET by studying twice, once without dialysate in the abdomen (drained) and once with 2 L of dialysate in the abdomen (full), and the relationship between body surface area (BSA) and delayed gastric emptying. 1) The mean of gastric emptying rate in 120 minute in patients with CAPD when drained (67.8+/-13.4%) was not different from that in healthy volunteers (65.4+/-8.6%) 2) The mean of gastric emptying rate in 120 minute when full (55.6+/-14.6%) was significantly lower than that when drained (67.8+/-13.4%) (P<0.05). In four of the 11 patients (36.4%), gastric emptying was extremely delayed from normal to abnormal range when full. 3) The BSA (1.5+/-0.11m2)of patients who had extremely delayed GET from normal to abnormal range was smaller than that (1.74+/-0.22m2) of patients who had minimal delayed or unchanged GET when full. This study showed the patient with CAPD had normal gastric emptying when drained, and that gastric emptying was delayed by dialysate dwelling, especially in the patients who has less than 1.5m2 of body surface area. Therefore, we suggest that intermittent nocturnal peritoneal dialysis or a small volume of dialysate may be considered for the patient with small body surface area based on the adequacy.
