Abstract
The pharmacokinetics, efficacy and safety of once-daily tacrolimus formulation (Tac-OD) were assessed in 34 stable pediatric kidney transplant recipients. Enrolled patients received their dose of twice-daily tacrolimus formulation (Tac-BID) on study Days 0 through 7. On the morning of study Day 8, the total daily doses for patients were converted to Tac-OD on a 1:1 basis and maintained on a once-daily morning dosing regimen. Tacrolimus pharmacokinetic profiles were obtained on study Days 7, 14 and 28 (after dose adjustment). Although the mean C0 concentrations (4.10 ± 1.16-3.53 ± 1.10 ng/mL, p = 0.004), and AUC0-24 (151.8 ± 41.6-129.8 ± 39.3 ng h/mL, p < 0.001) were decreased significantly after a 1:1 based conversion, there was high interindividual variability. The dose of Tac-OD was decreased in 26.5% and increased in 44.1% of patients. The resultant tacrolimus dose and pharmacokinetic profiles on study Day 28 were comparable to those on Day 7. There were no serious adverse events. In conclusion, Tac-BID can be safely converted to Tac-OD in stable pediatric kidney transplant patients with the heightened therapeutic drug monitoring. Effects of drug conversion on the cardiovascular risk factors, neurological side effects and adherence should be further evaluated.

Abstract
INTRODUCTION Abnormalities of calcium and phosphorus metabolism in end-stage renal disease patients can persist after transplantation. We investigated their natural courses after transplantation, their risk factors for posttransplantation hypercalcemia and hypophosphatemia, and their impacts on allograft outcomes. METHODS We retrospectively analyzed a total of 490 adult patients who underwent kidney transplantations between 2000 and 2009. RESULTS The serum calcium continued to increase, and reaching a plateau at around 3 months after transplantation. Thereafter it decreased, reaching a stable level by 2 years. Forty-four patients (9.0%) displayed hypercalcemia within 1 year; it persisted longer than that in 23 subjects (4.7%). Both longer dialysis duration (odds ratio [OR] 1.423; 95% confidence interval [CI], 1.192-1.699) and high intact serum parathyroid hormone (iPTH) level before transplantation (OR 1.002; 95% CI, 1.000-1.003) increased the risk for posttransplantation hypercalcemia. After a significant decrease during the first week, the serum phosphorus level increased, becoming stable between 1 and 6 months after transplantation. Hypophsphatemia occurred in 379 patients (77.3%) with 336 patients displaying hypophosphatemia without hypercalcemia. However, neither hypercalcemia nor hypophosphatemia influenced graft outcomes. Eight patients underwent pretransplantation parathyroidectomy, whereas 4 patients underwent posttransplantation parathyroidectomy. Neither group of patients experienced posttransplantation hypercalcemia. CONCLUSIONS Both hypercalcemia and hypophosphatemia are common after renal transplantation, especially among patients with a long history of dialysis before transplantation. Strict control of hyperparathyroidism including parathyroidectomy before transplantation may be the appropriate approach to these abnormalities.

Abstract
BACKGROUND We initially performed a study to evaluate the safety and efficacy of modified-release tacrolimus (FK506E) in a phase 3, 2-arm, 6-month, randomized, open-label, multicenter trial in Korean living donor de novo kidney transplant recipients. We then performed an extended study to evaluate the long-term safety and efficacy of a FK506E-based regimen up to 45 months posttransplantation in recipients already treated with FK506E. METHODS Initial study was designed as a randomized, open-label, comparative, multicenter study in de novo living donor kidney transplant recipients. The patients were randomized to an FK506E versus a control (FK506) group (1:1). Recipients who completed a 6-month FK506E treatment study were enrolled in the 39-month follow-up study. Primary end-points were patient and graft survivals at posttransplantation 45 months. Secondary end-point was the incidence of a clinical or biopsy-proven acute rejection episode between 6 and 45 months posttransplantation. RESULTS In the initial 6-month de novo study 124 enrolled patients were randomized into either the FK506E (n = 62) or the control group (n = 62). The incidence of an acute rejection episode was 19.4% (n = 12) in the FK506E versus 16.1% (n = 10) in the control group (P = .638). There was no mortality or graft failure among the 44 recipients enrolled in this additional 39-month follow-up study. There was 1 patient with biopsy-proven acute cellular rejection episode (2.3%) who underwent steroid pulse therapy with renal function recovery. At the time of study completion 40/44 recipients (90.9%) maintained FK506E treatment. CONCLUSION This 39-month study following the initial 6-month FK506E study period showed an FK506E-based immunosuppressive regimen in living donor kidney transplantation recipients to be safe and effective.

Abstract
BACKGROUND Melasma is characterized by increased pigmentation and photodamaged features, which include solar elastosis. Recently, we detected the downregulation of the genes most associated with lipid metabolism using microarray analysis in melasma. These findings suggested that lesional skin may have different biophysical characteristics, and, in particular, an altered skin barrier function. OBJECTIVE To determine the cutaneous biophysical characteristics of melasma. METHODS The melanin index, erythema index, stratum corneum hydration, sebum content and transepidermal water loss (TEWL) were measured for lesional and perilesional normal skin of 16 melasma patients and then compared. In addition, a skin biopsy was performed on 11 of the 16 study subjects to measure stratum corneum thickness and to study the protein expressions of PPAR-α and ALOX15B. RESULTS Melanin index, erythema index and stratum corneum hydration were significantly higher in lesional skin than in perilesional normal skin. No significant difference was found between lesional and normal skin in terms of basal TEWL level or sebum content. However, the rate of TEWL after barrier perturbation was significantly higher for lesional skin, and the barrier recovery rate was significantly delayed. Furthermore, a trend towards thinned stratum corneum was observed for lesional skin, and this was correlated with barrier recovery rate. The expressions of PPAR-α and ALOX15B were variable in the samples. CONCLUSIONS Melasma skin is characterized by impaired stratum corneum integrity and a delayed barrier recovery rate.

Abstract
Objective To define the anatomical variations of small saphenous vein (SSV) for varicose vein (VV) surgery by three-dimensional computed tomography venography (3D-CTV) and to analyse the impact of this preoperative evaluation on surgical outcomes. Methods A total of 120 consecutive limbs with SSV insufficiency having undergone VV surgery from January 2005 until December 2007 were enrolled. The medical records and images were analysed retrospectively. Results The relationship between SSV and gastrocnemial vein (GNV) were categorized into two: (a) SSV and GNV drained to popliteal vein (PV) separately (100 limbs, 87%) and (b) SSV and GNV made common channel which drained to PV (15 limbs, 13%). Saphenopopliteal junction morphology was normal (75 limbs), severe tortuosity near PV (19 limbs), ampullary ectasia (4 limbs) and duplicated drainage to PV (2 limbs). No recurrence of VV was noted. Conclusions CTV can provide thorough preoperative anatomic information of the SSV variations and reduce the recurrence of VV.

Abstract
SYNOPSIS Although skin pigmentation, which results from the production and distribution of melanin in the epidermis, is the major physiological defence against solar irradiation, hyperpigmentation is a common and distressing problem caused by various inflammatory skin disorders, such as eczema, allergic contact dermatitis and irritant contact dermatitis. We evaluated the effects of a preparation containing alpha-bisabolol on pigmented skin of a group of subjects. The effectiveness of the active compound, alpha-bisabolol, in a base-cream preparation for the treatment of pigmented skin was tested on 28 female subjects as follows: the cream was applied once a day to the back for 8 weeks. These same women also applied a vehicle control cream to the pigmented skin. The results were evaluated by clinical and biophysical test methods. After 8 weeks of treatment of the alpha-bisabolol-containing cream, there was significant lightening effect in the pigmented skin for the majority of the subjects who tested the cream.

Abstract
Candidemia in the pediatric burn population poses a management dilemma due to the paucity of good clinical data to guide treatment decisions. Whilst candidemia is less common than bacteremia in pediatric burns patients, it is associated with significant morbidity and mortality. We report a case of candidemia in an infant with 40% burns with ophthalmic complications secondary to nappy rash. We review the investigation and management of ocular candidemia.
