PURPOSE: We checked the levels of serum 25-hydroxyvitmain D (25OHD) in the patients with chronic kidney disease (CKD) to survey the status of vitamin D levels, to see the seasonal variations of 25OHD, and to evaluate the relationships among the levels of intact PTH, corrected calcium, and phosphorus. METHODS: We defined vitamin D insufficiency and vitamin D deficiency as serum 25-hydroxyvitamin D levels between 20 and 30 ng/mL and below 20 ng/mL, respectively. 185 patients in a single center were enlisted who categorized into 3 groups, CKD2-3, CKD4, and CKD5 by eGFR using MDRD7 equation. To see the seasonal differences of the levels of 25OHD, we collected laboratory data two times per each patient during summer division (April to September) and winter division (October to March). RESULTS: Prevalences of hypovitaminosis D were 42.8% (CKD2-3), 66.1% (CKD4), 92.8% (CKD5) in summer division and 48.7% (CKD2-3), 73.1% (CKD4), 92.8% (CKD5) in winter division. Seasonal difference of the levels of 25OHD was evident only in CKD stage 2-3 (p=0.018). Negative correlations were recognized between 25OHD and intact PTH (r=-0.2048, p<0.001), phosphorus (r=-0.1711, p=0.0011). CONCLUSION: Hypovitaminosis D is prevalent even in patients with early stages of CKD. The levels of 25OHD decreased significantly in winter division in patients with CKD stages 2-3. The levels of 25OHD were inversely correlated with those of intact PTH, phosphorus, respectively.

Aspergillus peritonitis is a rare but serious cause of peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. We report 2 cases of peritonitis caused by Aspergillus niger in CAPD which were treated successfully with voriconazole and caspofungin, respectively, and catheter removal. Both patients initially received amphotericin B; however, they were not cured with the agent. We briefly discuss the proper selection of antifungal agent and the treatment duration. Previously reported cases of the CAPD peritonitis caused by A. Niger are also reviewed in this article.

We report a case of a 25-year old man with chronic kidney disease with secondary hyperparathyroidism who had persistent elevation of serum parathyroid hormone level after the immediate total parathyroidectomy and autotransplantation. To localize supernumerary (ectopic) parathyroid gland, we checked Tc-99m MIBI scintigraphy, MDCT and PET-CT. Contrast-enhanced MDCT showed a small strong enhancing lesion over left bracheocephalic vein, and PET-CT showed multiple brown tumors. We removed the supernumerary parathyroid gland and got a rapid drop of parathyroid hormone level.

OBJECTIVES AND BACKGROUND: In head and neck cancer including hypopharyngeal carcinoma, cisplatin and 5-fluorouracil usually have been used as neoadjuvant chemotherapeutic agents. We investigated the difference in the influences of cisplatin and 5-fluorouracil (5-FU) on the p53 protein expression and cell responses (cell cycle arrest and apoptosis) in the hypopharyngeal cell line (PHUH-12). METHOD: PNUH-12 with a mutant type p53 (one point mutation at the 78th base, C to G, in exon 7) was treated with cisplatin and 5-FU. Changes in the cell line were assessed by MTT assay, Western blotting (p53 and p21 protein), DNA fragmentation, PI stain, and DNA flow cytometry. RESULTS: The p53 protein expression was increased after the treatment with cisplatin and 5-FU. The expression of p21 protein was increased after the treatment with 5-FU, not cisplatin. With cisplatin, we observed apoptosis by DNA fragmentation and PI stain and the increased S phase on DNA flow cytometry. But, with 5-FU, we couldn't observe apoptosis by DNA fragmentation, PI, and flow cytometry and only the increased G1 phase on DNA flow cytometry. CONCLUSION: In hypopharyngeal cell line (PNUH-12), cisplatin induced p53 dependent apoptosis and 5-FU induced p53 and p21 dependent G0/G1 cell cycle arrest, but not apoptosis.

Anemia is a common complication of hemodialysis. It reduces the quality of life and is recognized as adverse risk factor. The cause of anemia in CKD (chronic kidney disease) include lack of erythropoietin, gastrointestinal (GI) bleeding, hypothyroidism, hidden infection, and blood loss in hemodialysis. GI bleeding is not unusual complication in patient on maintenance hemodialysis, caused by uremia, medicine (NSAIDS, antiplatelet agents, anticoagulants), angiodysplasia, and ulcer. In CKD patients, GI bleeding is found in various sites over the whole bowel. Small bowel bleeding is one of the most common causes of obscure GI bleeding and constitutes 2-10% of all GI bleeding. Regarding the small bowel bleeding, diagnosis and treatment are much improved recently with the help of wireless capsule endoscopy and double or single balloon enteroscopy. We report a case of GI bleeding due to erosion of small bowel, which was diagnosed and treated with the single-balloon enteroscopy in patients on maintenance hemodialysis.

Secondary hyperparathyroidism is one of the most common complications of patients with chronic kidney disease (CKD). Mandibular enlargement, metastatic pulmonary calcification, and gastric mucosal calcinosis are rare complications in these patients. The defect of calcium and phosphorus metabolism may precipitate pathologic calcification at diverse organs and soft tissue, and change bone architecture. In case of involving periarticular area, patients usually present with localized swelling, pain, and reduced mobility in affected sites. However, in case of organ involvement, except in an advanced stage of disease, there are no specific symptoms. Among these patients, treatment strategies include tight control of calcium and phosphate levels, parathyroidectomy for hyperparathyroidism, renal transplantation, and local excision of calcific lesions. We report a case of mandibular enlargement, metastatic pulmonary calcification, and gastric mucosal calcinosis due to CKD with improvement 3 months after medical and surgical treatment.

BACKGROUND: Anemia is a major risk factor that contributes to mortality in patients with chronic kidney disease. There is controversy over the optimal hemoglobin (Hb) target in these patients. This study investigated the association between Hb level and mortality in a cohort of hemodialysis (HD) patients in Korea. METHODS: This study was a multicenter prospective observational study of maintenance HD patients that was performed for 5 years in western Seoul, Korea. Three hundred and sixty-two participants were enrolled. Laboratory values and mortality were accessed every 6 months. Repeated measures of laboratory values in each interval were averaged to obtain one semiannual mean value. The Hb values were divided into six groups: (1) Hb<9 g/dL; (2) 9 g/dL< or =Hb<10 g/dL; (3) 10 g/dL< or =Hb<11 g/dL; (4) 11 g/dL< or =Hb<12 g/dL; (5) 12 g/dL< or =Hb<13 g/dL; and (6) Hb> or =13 g/dL. We analyzed the odds ratio for all-cause mortality, based on the Hb group, and adjusted for demographics and various laboratory values. Statistics were performed with SAS, version 9.1 software (SAS Institute Inc., Cary, NC, USA). RESULTS: Mortality odds ratios relative to the reference group (10-11 g/dL) in the fully adjusted model were 3.61 for<9 g/dL; 3.17 for 9-10 g/dL*; 4.65 for 11-12 g/dL*; 5.50 for 12-13 g/dL*; and 2.05 for> or =13 g/dL (* indicates P<0.05). CONCLUSION: In this study, a Hb level of 10-11 g/dL was associated with the lowest mortality among the groups with Hb level<13 g/dL. Larger interventional trials are warranted to determine the optimal Hb target for Korean HD patients.

Maxillary enlargement is a rare complication of secondary hyperparathyroidism (SHPT). A 35-year-old Korean man undergoing chronic hemodialysis presented with a painless enlargement involving the maxilla and mandible. Plain radiography and CT scan showed bony expansion at the maxilla and mandible with multiple radiolucency. Serum intact parathyroid hormone (iPTH) was >1,600 pg/mL. Tc-99m sestamibi (MIBI) parathyroid scan and neck sonogram were compatible with SHPT. He underwent limited parathyroidectomy and commenced a course of paricalcitol. Fifteen months after surgery, maxillary enlargement and bony resorptions involving both hands markedly improved. Thirty-six months after the surgery, the serum iPTH level was 109.3 pg/mL. This is the first report in Korea documenting a patient with maxillary enlargement in SHPT who was successfully treated with limited parathyroidectomy and paricalcitol.

Objective To explore the effects of Valpar Component Work Sample on Parkinson's disease (PD). Methods From June, 2015 to June, 2017, 40 patients with PD were randomly divided into control group (n=20) and observation group (n=20). Both groups received routine treatment and occupational therapy, while the observation group accepted rehabilitation with Valpar Component Work Sample in addition, for eight weeks. They were assessed with Unified Parkinson's Disease Rating Score II and III (UPDRSII and UPDRSIII), Mini-Mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and the Parkinson's Disease Questionnaire-39 (PDQ-39) before and after treatment. Results The scores of UPDRSII, UPDRSIII, MMSE, HAMD, and HAMA, and Summary Index of PDQ-39 improved in both groups (t>2.864, P<0.05) after treatment, and improved more in the observation group than in the control group (t>2.237, P<0.05). Conclusion Combined with Valpar Component Work Sample may further improve the activities of daily living, motor, cognitive function, depression and anxiety, and then quality of life in patients with PD.
