BACKGROUND: Rifampin reduces the blood levels of cyclosporin (CsA) and steroids by increasing the activity of hepatic cytochrome P450 system and the inclusion of rifampin in the anti-tuberculosis treatment protocol increases the risk of acute allograft rejection and mortality due to its interaction with cyclosporine. We report the successful treatment outcome of post-renal transplant tuberculosis patients who were treated with quinolone substituted for rifampin in anti-tuberculosis regimen. METHODS: This was a retrospective study of 14 patients with tuberculosis diagnosed among 218 transplant recipients from Feb. 1988 through Dec. 2003 at Daejeon St. Mary's hospital of catholic university of Korea and 6 patients with tuberculosis who underwent transplantation in other hospital and followed up in our hospital. RESULTS: The incidence of post-renal transplant tuberculosis was 6.4%. The mean time to diagnosis of tuberculosis after transplantation was 58.6 months (3.3~180.7). 9 were pulmonary and 11 were extrapulmonary tuberculosis. The graft failure was not occurred in quinolone group (0/15) and 2 of 3 in rifampin group. The serum creatinine levels before tuberculosis were not different to that of post-treatment in quinolone group. (P=0.58) The CsA levels before tuberculosis were not also different to that of posttreatment in quinolone group (P=0.68). CONCLUSIONS: The treatment of post-renal transplant tuberculosis with rifampin sparing anti-tuberculosis regimen was successful. Rifampin, although a mainstay drug in the treatment of tuberculosis, can be avoided in patients receiving cyclosporine, thus avoiding the risk of precipitating allograft rejection.

PURPOSE:Preconditioning due to activation of AMPK might reduce ischemia-reperfusion (I/R) injury in the kidney, based on the key role of AMPK in preserving ATP. To evaluate this possibility, the effect of preconditioning with 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), AMPK activator, before sustained ischemia was investigated. METHODS:Adult male Sprague-Dawley rats weighing approximately 220-250 g were used. To induce renal ischemia, a laparotomy was performed under ketamine and xylazine hydrochloride, and the blood supply to both kidneys was interrupted by placement of vessel clamps at the level of the renal pedicles. Reflow was initiated by removing the clamps. The following experimental groups were defined 1. Acute renal ischemia 0 sec, 10 min, 15 min, 2. AICAR treatment, 3. Sham group (S), 4. Ischemia/ Reperfusion group (I/R), 5. AICAR+I/R group (A+I/R), 6. AraA (Adenine-9-b-D-arabinofuranoside, an AMPK) inhibitor+AICAR+I/R group (AraA+A+I/R) RESULTS:There was only faint AMPK phosphorylation in the sham group. After 10 minutes of ischemia, or AICAR preconditioning however, Thr172 phosphorylation of AMPK was increased (p<0.05). The serum levels of BUN and creatinine were significantly decreased in AICAR preconditioning group (A+I/R). (128.0+/-7.33 mg/dL, 4.18+/-0.27 mg/dL vs. 90.2+/-11.13 mg/dL, 2.58+/-0.7 mg/dL, p<0.05), but these effects were attenuated by AMPK inhibitor, AraA (AraA+A+I/R group). In quantitative analysis of tubular injury, tubular injury score in AICAR preconditioning group significantly decreased (p<0.05). CONCLUSION:The AMPK activator AICAR has a protective effect against renal I/R injury.

BACKGROUND: Medical skin care is essential for the treatment of skin diseases all over the world. Medical skin care is also part of medical practice and this must be differentiated from the simple skin care that is given for normal healthy skin. OBJECTIVE: We wanted to discuss medical skin care and the related medical devices and legal issues. METHODS: We reviewed the related laws and regulations, we consulted experts and associations and we analyzed the result of the survey. RESULTS: Legally, medical skin care and simple skin care are well classified. However, many illegal procedures are still performed by non-medical personnel and many adverse effects have been reported as a result. Furthermore, there are no legal restrictions for the performer based on the grade of each medical skin care procedure. CONCLUSION: For the best results and safe procedures, medical skin care must be performed by approved medical equipment under the supervision of a physician or medical personnel. Continuous control and guidance by the government is strongly needed.

PURPOSE: Cardiovascular disease is one of the leading causes of mortality and morbidity in hemodialysis patients. Arterial stiffness is known to be associated with vascular calcification in HD patients. Post-dialysis hypotension is a risk factor for cardiovascular mortality. We evaluated the relation between arterial stiffness and post-dialysis blood pressure in maintained HD patients. METHODS: 72 HD patients were enrolled in this study. They had been under maintenance HD for more than 3 months. We checked the biochemical data, including the troponin T, CRP and OPG (osteoprotegerin) levels before their dialysis session and the baPWV (brachio-ankle pulse wave velocity) after the session. We defined post-dialysis BP decrease as a drop of BP of more than 5% of the average MAP for 2 weeks (6 sessions). RESULTS: There were 34 and 38 patients with and without post-dialysis BP decrease, respectively. The BP decrease group had higher CRP, troponin T and OPG levels (p<0.05, 0.01 and 0.01, respectively). The PWV was higher in the BP decrease group (p<0.001). The CRP and troponin T levels were positively correlated with the PWV (r=0.26, p<0.05; r=0.31, p<0.01, respectively). The OPG level was positively correlated with the PWV (r=0.44, p<0.001). Age, pre-dialysis pulse pressure and drops in the patients MAP were correlated with the PWV (r=0.33, p<0.05; r=0.31, p<0.05; r=0.30, p<0.05, respectively). On multivariate analysis, PWV was the independent factor related to the drops in the MAP of the patients (beta=0.311, p=0.021). CONCLUSION: Arterial stiffness is associated with post-dialysis blood pressure decrease.

Severe hypercalcemia due to persistent hyperparathyroidism after kidney transplantation causes serious medical complications. Medical or surgical treatment is recommended to decrease serum calcium level, but percutaneous ethanol injection therapy (PEIT) is an also useful method for patients who are refractory to medical treatment and under poor condition for parathyroidectomy. Here, we report a case of successful PEIT of refractory hypercalcemia in a 62-year old patient after kidney transplantation. This patient underwent PEIT because of poor general condition. Just after PEIT, serum calcium level was normalized and biointact PTH level was markedly decreased without serious complications. He has been followed up for 6 months without recur so far. PEIT may be recommended for treatment of sustained hypercalcemia in kidney-transplant patients who are refractory to medical treatment or in poor condition for surgical treatment.

Recurrent urinary tract infection due to vesicoureteral reflux is one of the important medical complications in renal transplant recipients. Injection of macroplastique is recommended to reduce the vesicoureteral reflux, but it can result in poor responses. Ureteroureterostomy is an invasive method, but it is advisable in patients with higher grades of vesicoureteral reflux that do not respond to medical or macroplastique injection. We here report on two cases of successful treatment of vesicoureteral reflux by ureteroureterostomy. These patients experienced repeated episodes of acute pyelonephritis in spite of long-term antibiotic treatment and repeated macroplastique injection. No more urinary tract infection was observed after ureteroureterostomy. We recommend ureteroureterostomy in renal transplant recipients who suffer with repeated acute pyelonephritis due to vesicoureteral refulx.

A 51-year old man presented with generalized edema for 10 days. He was admitted to the hospital for a renal biopsy, and a pancreatic mass was incidentally detected by ultrasonography. The renal biopsy was consistent with membranous glomerulonephritis and the pancreas biopsy revealed chronic granulomatous inflammation with multinucleated giant cells, which was suggestive of tuberculosis of the pancreas. The patient was initially treated with a steroid and anti-tuberculosis drugs, but the proteinuria in the nephrotic range persisted throughout the 3-month follow-up. With the presumed diagnosis of tuberculosis-induced membranous nephropathy, immunosuppressant therapy was stopped and anti-tuberculosis drugs were administered for 31 months. With anti-tuberculous treatment, the proteinuria was reduced from 22 g/day to 0.57 g/day. A follow-up abdominal CT revealed a marked reduction in the size of the pancreatic mass. This finding suggests that the membranous nephropathy in our case was related to the pancreatic tuberculosis rather than it being related to primary nephrotic syndrome.

PURPOSE: Kidney size (KS) is used to diagnose the patients with renal disease. When the length of a kidney is measured under 9 cm, it is considered to indicate an irreversible disease. Because glomerular filtration rate (GFR) decreases with age, the normal range of KS in the elderly is indefinite. Therefore, we measured KS in adults older than 80 years old and investigated correlated factors. METHODS: One hundreds six adults (51 men, 55 women: mean age 83+/-0.3) without renal disease were included. Their serum creatinine (Scr) levels did not exceed 1.3 mg/dL, and the calculated GFR were over 60 mL/min/1.73m2. Abdominal ultrasonography were performed to all of them and their body indexes (BI) were measured. RESULTS: 1) The mean length of kidney was 9.9+/-0.07 cm. 2) KS in the early eighties was larger than that of adults over ninety. 3) KS showed negative correlations with age and Scr, but a positive correlation with body surface area . 4) The calculated GFR showed correlations with the surface areas of both kidney (BK) by C-G equation and with the size of BK by MDRD equation. 4) The GFR calculated by MDRD and C-G equation presented inverse correlations with Scr, but only MDRD equation showed a statistic significance. CONCLUSION:In the elderly, KS may be smaller than that of younger adults. Other factors such as either surface area or volume of BK and BI should be considered to estimate the individual KS to decide whether the size is within normal range.

The development of anuria after appendectomy is usually related to complications associated with appendicitis or with the surgical sequelae of appendectomy. We report an unusual case of anuria after appendectomy in a 20-year-old woman. The patient was transferred to our hospital due to a sudden cessation of urine output just after appendectomy. We initially suspected that the anuria was caused by a complication of surgery. However, a review of her medical history and an abdominal computed tomography (CT) scan revealed that a distal ureteral stone in a single kidney had caused the anuria. There are few cases in the literature regarding a distal ureteral stone in a single kidney. This case indicates the importance of radiological evaluation in the differential diagnosis of acute appendicitis, especially in patients with unilateral renal agenesis.
