Abstract
Purpose To evaluate the effect of horizontal muscle surgery (recession or recession plus resection) on the anterior chamber parameters in patients after strabismus surgery. Patients and Methods. The Scheimpflug of 18 eyes of 12 patients with horizontal deviations were recorded just before surgery and 1 month after surgery. The power of anterior surface of cornea in horizontal and vertical axis, thinnest corneal thickness, anterior chamber depth, anterior chamber volume, and cornea volume were analyzed. The clinical characteristics of patients, the size of the deviations, the surgical doses, and observed responses to surgery were reviewed. Results There were six male and six female patients with an average age of 11.4 years (range, 4 to 22 years). Mean preoperative deviation was 47.91 PD (range, 20 to 75 PD), eight patients had esotropia with 57.5 PD average deviation (range, 40 to 75 PD), and four patients had exotropia with 28.75 PD average deviation (range, 20 to 35 PD). Of these 18 eyes, 12 eyes had horizontal muscle recession and 6 eyes had recession plus resection surgery. At the end of 1 month, three patients were orthophoric and eight patients had residual deviations varying between 16 and 35 PD. Preoperative and postoperative comparison of the whole study group documented insignificant changes in anterior chamber parameters and in keratometer readings. However, after dividing patients into two groups–recession or recession plus resection group–only one parameter, anterior chamber volume, was significantly reduced in recession plus resection group. Conclusions Patients with strabismus who undergo recession plus resection procedure are prone to change in anterior chamber volume. Study with larger groups and long follow-up is necessary for clearer documentation of alterations at anterior chamber parameters.

Abstract
BACKGROUND Behçet's disease (BD) is an idiopathic, multisystemic, progressive disease. The purpose of this study is to compare the knee flexor and extensor isokinetic muscle strengths of Behcet's patients with that of healthy subjects. METHODS Twenty-five (13 male and 12 female) patients with BD and 25 (15 male and 10 female) healthy individuals were included in the study. Velocities of 90°/sec, 120°/sec, and 150°/sec were used for the isokinetic muscle strength testing. Patients with active inflammatory knee arthritis were excluded. Peak torque (Nm) and peak torque adjusted to body weight (%) were taken into consideration for comparison between study groups. RESULTS Compared to healthy controls, there was a statistically significant decrease in both the bilateral knee extensor and flexor muscle isokinetic peak torques(Nm) as well as the peak torques adjusted to body weight (%) at velocities of 90°/sec, 120°/sec and 150°/sec in patients with BD (p < 0.05). However, there was no significant difference in the agonist-antagonist ratio of the isokinetic peak torques of knee muscles between the two groups. CONCLUSION In light of these findings, we have concluded that both knee flexor and extensor isokinetic muscle strengths are lower in BD. We therefore recommend careful monitoring of patients with BD in terms of muscle strength.

Abstract
BACKGROUND Vitiligo is an acquired depigmentation disorder, and oxidative stress is suggested to have a major role in its aetiopathogenesis. AIM To assess whether oxidative stress has a greater role in generalized than in localized vitiligo. METHODS We assessed 31 patients with active vitiligo (17 localized, 14 generalized) and 38 healthy controls. Serum total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) were determined. RESULTS Patients with vitiligo had significantly lower TAS and higher TOS and OSI values than controls. Both localized and generalized vitiligo were associated with lower TAS and higher TOS and OSI values, compared with controls, and all three did not differ with vitiligo type. CONCLUSIONS A systemic oxidative stress exists in patients with vitiligo. These results indicate that the global antioxidant capacity of patients might have been exhausted through a defence mechanism against oxidative processes. The imbalance in TOS/TAS status may have an important role in the aetiopathogenesis of vitiligo, regardless of the clinical variant of the disease.

Abstract
Rapid allograft infection complicates liver transplantation (LT) in patients with hepatitis C virus (HCV). Pegylated interferon-α and ribavirin therapy after LT has significant toxicity and limited efficacy. The effect of a human monoclonal antibody targeting the HCV E2 glycoprotein (MBL-HCV1) on viral clearance was examined in a randomized, double-blind, placebo-controlled pilot study in patients infected with HCV genotype 1a undergoing LT. Subjects received 11 infusions of 50 mg/kg MBL-HCV1 (n=6) or placebo (n=5) intravenously with three infusions on day of transplant, a single infusion on days 1 through 7 and one infusion on day 14 after LT. MBL-HCV1 was well-tolerated and reduced viral load for a period ranging from 7 to 28 days. Median change in viral load (log10 IU/mL) from baseline was significantly greater (p=0.02) for the antibody-treated group (range -3.07 to -3.34) compared to placebo group (range -0.331 to -1.01) on days 3 through 6 posttransplant. MBL-HCV1 treatment significantly delayed median time to viral rebound compared to placebo treatment (18.7 days vs. 2.4 days, p<0.001). As with other HCV monotherapies, antibody-treated subjects had resistance-associated variants at the time of viral rebound. A combination study of MBL-HCV1 with a direct-acting antiviral is underway.

Abstract
BACKGROUND Recent studies suggested that increased oxidant products and decreased antioxidant system functions may be involved in the pathogenesis of psoriasis. In this study, we investigated total oxidative status, Paraoxonase (PON)1/arylesterase enzyme activities and severity of the disease in smoker and non-smoker psoriatic patients. METHODS Fifty-four patients with plaque type psoriasis (28 smokers and 26 non-smokers) and 62 healthy volunteers (16 smokers and 46 non-smokers) were enrolled in the study. Serum total oxidant status (TOS), total antioxidant capacity (TAC) and arylesterase levels were measured, and oxidative stress index (OSI) was calculated in all participants. RESULTS Psoriasis Area and Severity Index scores were significantly higher in smoker patients than in non-smoker patients (P = 0.014). Both smoker and non-smoker patients had significantly increased TOS levels and OSI values and decreased TAC levels than healthy subjects (all P values = 0.000). The TAC and TOS levels, OSI values and arylesterase activities were similar between smoker and non-smoker patients. The levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL) and high-density lipoprotein (HDL) were not significantly different between smoker and non-smoker psoriasis patients. When compared with non-smoking controls, only smoking psoriasis patients had significantly higher TG (P = 0.005), lower HDL (P = 0.022) and lower arylesterase levels (P = 0.015). There were no significant correlations with Psoriasis Area and Severity Index (PASI) scores and TAC, TOS, OSI, TG, TC, HDL and LDL levels in all psoriasis patients. CONCLUSIONS Oxidative stress is increased in psoriasis patients regardless of their smoking status. The decreased arylesterase activity in smoker psoriasis patients suggested that smoking may be a considerable risk factor that increases the severity of psoriasis by increasing oxidative stress in these patients.

Abstract
Brucellosis is considered the most widespread zoonosis in the world. It has been reported that the prevalence of seropositivity among the Turkish population varies from 3% to 14%. We present a case of brucellosis after pediatric liver transplantation. A 15-year-old boy with the diagnosis of neuro Wilson's disease underwent deceased-donor liver transplantation. The postoperative immunosuppressive protocol consisted of steroids and tacrolimus. Two months after the operation the patient experienced fever to 40°C. The patient complained of poor appetite, headache, and diarrhea. He had had pancytopenia. Despite administration of appropriate antibiotics, antiviral and antifungal agents, fever persisted for > 1 month. Multiple blood, urine, stool, and sputum cultures were negative. Bone marrow aspirate revealed hypocellularity. Liver biopsy was performed, but rejection was not observed on biopsy specimen. Brucella serology was positive and Brucella agglutination titer was 1:320. Bone marrow culture was positive for Brucella but blood culture was negative. The patient was then treated with oral doxycycline and rifampin for 8 weeks. No previous case report about Brucella infection after liver transplantation has appeared in the literature, to our knowledge; our case is presented as the first. Bone marrow hypoplasia is a rare feature of Brucella infection. Our patient with brucellosis and pancytopenia had had hypocellular bone marrow. The clinical and hematologic findings resolved with treatment of the infection. Brucella infection should be suspected in liver transplanted recipients with fever of unknown origin, especially in a recipient who has lived in an endemic area. Brucella also should be considered as a possible diagnosis in patients with pancytopenia.

Abstract
Rejection is independently associated with liver graft loss in children. We report the successful rescue of grafts using ATG+/-OKT3 in late rejection associated with cholestasis. Retrospective chart review was performed after IRB approval. Between 2003 and 2010, 14 pediatric liver transplant recipients received anti-lymphocyte treatment for "cholestatic" rejection. Median age at transplantation was 12.7 yr (range 0.9-23.4), eight were boys, and immunosuppression was tacrolimus based. Median time from transplantation to rejection was five yr (range 1.1-10.5). Median peak total bilirubin was 11.1 mg/dL (range 1.4-18). All showed moderate to severe acute rejection and hepatocellular cholestasis on histology. ATG/OKT3 was started as first-line therapy in six and in the remaining eight as second-line therapy after failure of pulse steroids. Thirteen responded with normalization of aminotransferases and bilirubin, median time 16 wk (range 7-112); one non-adherent recipient has still not achieved normal graft function at last follow-up. Patient survival is 100%, with no re-transplantation and no post-transplant lymphoproliferative disease, median follow-up 2.9 yr (range 1.1-7.2). Cholestasis associated with acute rejection occurring late after liver transplantation may herald steroid resistance. First-line therapy with anti-lymphocyte preparations, prophylactic anti-microbial therapy, and close monitoring allow excellent rates of patient and graft survival.

Abstract
Combined liver kidney transplantation (LKT) can be successfully performed on patients with liver and renal failure; however, outcomes are inferior to liver transplantation alone (OLT). Our aim was to determine the indications for and outcome of LKT and whether patients with longer wait times required more frequent LKT versus OLT alone. We included 18/93 adults who underwent LKT from August 2007 to August 2010 for hepatitis C virus (HCV, n = 7), alcohol (n = 5), nonalcoholic steatohepatitis (n = 2), primary biliary sclerosis, polycystic kidney disease with liver involvement, hepatic adenomatosis, and ischemic hepatitis. Eleven were originally listed for LKT and 7 required listing for-kidney transplantation while awaiting OLT. Eight were on dialysis when first listed and 10 had a low glomerular filtration rate or known kidney disease. The mean calculated Model for End-Stage Liver Disease (MELD) score for LKT was 31.2 ± 3.54. Seven had hepatocellular carcinoma in explants. Two patients had acute cellular kidney rejection that responded to treatment. Recurrence of HCV was documented in 5 patients within 6 months of LKT; 2/5 received HCV therapy (interferon and ribavirin) without renal allograft rejection. One-year liver graft/patient survival was 94% after LKT. One patient died at 6 months post LKT due to severe HCV recurrence. Last mean serum creatinine level was 1.35 ± 0.28 mg/dL for LKT patients. LKT is a safe procedure with favorable outcomes even in patients with a high MELD score. Transplantation of patients with a high MELD score due to regional variations in organ allocation results in additional use of kidneys by OLT patients. Improved organ allocation algorithms in OLT would help to reduce combined transplants, sparing more kidneys.

Abstract
Liver transplantation (OLT) has become the only treatment modality for patients with end-stage liver diseases. Establishment of standard liver transplantation technique, development of better immunosuppressive medications and accumulated experience using them safely, and improvement of intensive care and anesthesia played major role to have current 88%-90% 1-year survival after liver transplantation. As liver transplantations became more successful with the growing experience and development in the field, the increased demand for liver allografts could not match the available supply of donor organs. As a result of this imbalance, each year nearly 3000 patients die in the United States awaiting liver transplantation on the national waiting list. Split liver transplantation (SLT) has been perceived as an important strategy to increase the supply of liver grafts by creating 2 transplants from 1 allograft. The bipartition of a whole liver also carries utmost importance by increasing the available grafts for the pediatric patients, where size-matched whole liver allografts are scarce, leading increased incidence of waiting list mortality in this group. In the common approach of the split liver procedure, liver is divided into a left lateral segment graft (LLS) to be transplanted to a child and a right extended liver lobe graft for an adult recipient. In a technically more challenging variant of this procedure, the principle is to split the liver into 2 hemigrafts and use the left side for a small adult or a teenager and the right for a medium-sized adult patient. Donor selection for splitting, technical expertise in both OLT and hepatobiliary surgery, logistics to decrease total ischemia time, and manpower of the transplantation team are important factors for successful outcomes after SLT. The liver can be split on the back table (ex situ) or in the donor hospital before the donor cross-clamp using in situ splitting technique, which was developed directly from living donor liver transplantation. The most important advantage of in situ splitting is to decrease the total ischemia time and increased the possibility of inter-center sharing. The in situ technique of splitting has other advantages, including evaluation of the viability of segment IV in case of LLS splitting and better control of bleeding from cut surface upon reperfusion on the recipient. Recipient selection for split liver grafts is also crucial for success after SLT. In this review, we aim to summarize the advances that have occurred in SLT. We also discuss anatomic and technical aspects, including both approaches to SLT, which is now considered by many centers to be a routine operation.

Abstract
OBJECTIVES Vision plays an important role in postural stability. It has also been shown that visual information from the environment and visual cues significantly contribute to balance skills. The aim of this study was to investigate the effects of visual acuity on postural stability and mobility before and after cataract surgery. METHODS The study group was composed of 25 male and 11 female patients (age 57-84, mean 66.6 +/- 4.7) who had been operated for age-related cataract. Postural stability and mobility were assessed before and four weeks after the surgery by means of Biodex stability system (BSS), Tinetti, Time up and go (TUG) and Functional reach (FR) tests, as well as by gait analysis (gait velocity, step length, step width, cadence, stride length). RESULTS Postoperative visual acuity was significantly improved. Gait velocity and cadence increased significantly but step length, stride length, and step width did not change significantly. Postoperative improvement of Tinetti balance, TUG and FR tests were significant. Similarly, antero-posterior stability index (APSI), mediolateral stability index (MLSI) and overall stability index (OSI) that were examined with BSS improved significantly after the cataract surgery. CONCLUSION These results demonstrated that gain in visual acuity after cataract surgery improves the postural stability and mobility of patients (Tab. 2, Fig. 1, Ref. 29).

Abstract
BACKGROUND Because of a critical shortage of deceased donor (DD) livers, more extended criteria allografts are being utilized; these allografts are at increased risk for ischemia-reperfusion injury (IRI). We assessed whether, in a large cohort of patients transplanted for hepatitis C virus (HCV) either via a DD or live donor (LD), there was a relationship between the degree of IRI and the frequency and timing of acute cellular rejection (ACR) and histologic HCV recurrence. METHODS During an 8-year study, patients were separated into four groups based on peak alanine aminotransferase (ALT) levels and three groups based on severity of IRI on postreperfusion liver biopsy. RESULTS The mean follow-up time of 433 DD and 44 LD recipients was 1212 days. We noted a strong correlation in DD between peak ALT and the histologic degree of IRI (P = .01). There was no difference in the incidence or grade of ACR among the four groups. There was no correlation between the severity of IRI and the incidence or time to histologic recurrence of HCV. CONCLUSIONS The magnitude of peak ALT correlated with the severity of IRI on postreperfusion liver biopsy. Among this large HCV cohort, there was no correlation between the severity of IRI and the incidence or timing of histologic HCV recurrence or incidence of ACR.

Abstract
We describe results from a clinical program, which aimed at improving adherence to medications in children who had a liver transplant. We followed the medical outcomes of 23 children and adolescents who participated in a clinical adherence-improvement protocol during the years 2001-2002. The protocol included identification of non-adherent patients by examining tacrolimus blood levels and intervention by increasing the frequency of clinic visits for non-adherent patients. In the two-yr preintervention (1999-2000), there was no improvement in any of the outcomes. After the intervention, the number of patients with high alanine aminotransferase levels (100 and above) decreased significantly, from eight before the intervention to four afterwards. Other outcomes, including the number of rejection episodes (three before, none after) and the degree of adherence to tacrolimus, also improved, but the improvement did not reach statistical significance. Although non-adherent patients were called to clinic more often under the protocol, the intervention did not lead to increased outpatient costs. This adherence--improvement intervention appears to be promising in improving outcomes in pediatric liver transplant recipients. Larger, controlled studies are needed to establish the efficacy of this or other approaches.

Abstract
The pharmacokinetics, safety and tolerability of a once-daily formulation of tacrolimus (tacrolimus extended-release formulation; XL formerly referred to as MR or MR4) were assessed in 18 stable pediatric liver transplant recipients who were converted from the twice-a-day formulation of tacrolimus (TAC) to XL. Patients received their twice-a-day dose of TAC on study days 1 through 7. Beginning on the morning of study day 8, patients were converted to XL on a 1:1 (mg:mg) basis for their total daily dose, and were maintained on a once-daily AM dosing regimen using the same therapeutic monitoring and patient care techniques employed with TAC. Based on pharmacokinetic profiles obtained on study days 7 (TAC) and 14 (XL), steady state exposure (AUC(0-24)) was equivalent between XL and TAC; the mean XL/TAC ratio for lnAUC(0-24) was 100.9% (90% CI: 90.8%, 112.1%). AUC(0-24) and C(min) were strongly correlated at steady state (correlation coefficient: XL 0.90, TAC 0.94). During the first year post-conversion, there were no cases of acute rejection, discontinuation of XL, graft loss or death. The safety profile of XL was consistent with that known for TAC. These results support the safe and convenient conversion of pediatric liver transplant recipients from twice-a-day TAC to once-daily XL.

Abstract
INTRODUCTION Prior to transplantation of segmental liver grafts to adult recipients, it is crucial to confirm that the graft size is safe for the donor, yet adequate for the recipient's metabolic needs. Computed tomography (CT) and magnetic resonance imaging (MRI) are the current best standards. We applied a new formula to estimate right liver lobe weight in living donors and compared our results with CT and MRI. METHODS Between August 1998 and December 20, 91 adults received right lobes from living donors. Donor liver volumes were assessed by CT or MRI. Actual weights of right lobe grafts were determined after back table flushing. We estimated whole liver weights using the formula: 772 x body surface area (BSA). Right lobe liver weight was calculated as 57% of the estimated whole liver weight (R-57). RESULTS Mean actual right lobe weight (n = 90) was 855.83 +/- 183.4 g. Estimated right lobe weight was 858.08 +/- 90.80 (R-57, P = NS); 1077.35 +/- 263.07 mL for CT (P = .0001), and 1185.07 +/- 350.10 mL for MRI (P = .0001). Mean graft-recipient weight ratio (GRWR) was 1.23%; there was no significant difference with R-57 GRWR but there was a difference from CT and MRI-GRWR (P = .001). The proportion of cases of estimated right lobe weight and GRWR within 20% of the corresponding actual value were 80% and 90%, respectively, for R-57 versus 36% and 43% for the imaging studies (P = .0001). CONCLUSION With readily available software to calculate BSA, physicians can predict right lobe weight knowing only the donor's height and weight. CT and MRI will only be necessary for anatomic liver mapping.

Abstract
Granuloma annulare occurs as an idiopathic and benign condition, although it may be associated with some neoplasms. We describe a 60-year-old man with granuloma annulare on dorsal hands who developed prostate carcinoma. To the best of our knowledge, this is the first case report of granuloma annulare with prostate carcinoma. Granuloma annulare, especially in older age groups, may be classified as a sign of various carcinomas.

Abstract
INTRODUCTION In cadaveric or segmental liver transplantation, accurate assessment of graft volume is desirable but not always easy to achieve based on donor morphometric data. We sought to establish a simple, reliable formula for accurate prediction of liver volume. METHODS Data from 1,413 cadaveric adult and pediatric liver donors were analyzed using simple and multiple regression analysis. Liver weight (LW) was plotted against age, height, body weight (BW), body surface area (BSA) or body mass index (BMI); a formula was developed using simple regression: LW (g) = 772 (g/m(2)) x BSA, r = 0.73, P <.01. For donors with BSA </=1.0, a pediatric factor (PF) of 1.0 was included, resulting in the formula: LW (g) = 772 (g/m(2)) x BSA - 38PF, r = 0.73, P <.01. We then applied our formula on 5 published formulae to estimate LW of our donors. RESULTS Among donors with BSA >1.0, there was no significant difference between the actual and the estimated mean LW as calculated by the new formula. For pediatric donors, there was no significant difference between estimated and actual mean liver weight with any formula. When the new formula was applied, the difference between the actual and the estimated liver weight was acceptable (<20%) in 1040 (73.6%) cases. In all races, there was no significant difference between actual and estimated mean liver weight as calculated by this formula. CONCLUSIONS A simple formula to calculate liver weight in donors with BSA >1.0 is: LW = 772 x BSA, and for donors with BSA </=1.0: Liver Weight = 772 x BSA - 38.

Abstract
We reviewed the results of 50 magnetic resonance (MR) cholangiograms to evaluate their usefulness in directing clinical management in young patients after liver transplantation (LTx). Thirty-two patients underwent 50 MR cholangiograms on a 1.5-T unit. Studies were performed from 1 week to 16 yr after LTx. Indications included biochemical abnormalities with (n = 19) or without (n = 16) biopsy evidence for chronic rejection, sepsis (n = 14), and intractable ascites (n = 1). Original interpretations were compared to laboratory and ultrasound findings, and clinical outcome. Of 19 studies performed on 14 patients with biopsy evidence of chronic rejection, 16 were abnormal on MR (but only one was abnormal on ultrasound), resulting in corrective surgery (n = 1), re-Tx (n = 1), and endoscopic dilatation (n = 1). Of 16 studies on 16 patients with biochemical abnormalities without evidence of chronic rejection on biopsy, 14 were abnormal on MR (but only five of 13 on ultrasound), leading to corrective surgery (n = 3) and re-listing for Tx (n = 3). Thirteen of 14 studies on six patients with sepsis were abnormal on MR (five of nine were abnormal on ultrasound), identifying surgically correctable strictures (n = 2), and leading to re-Tx (n = 1) and percutaneous biliary drainage procedures (n = 2). The one patient with ascites had a normal study. We advocate usage of MR cholangiography for the detection of biliary complications after LTx, particularly in those patients who present with biochemical abnormalities that are not easily explained by acute cellular rejection or viral infection and in those with biliary sepsis.

Abstract
INTRODUCTION Acute leukemia is rare after solid organ transplantation. METHODS Review of data on 3 patients with acute leukemia identified among 1365 who underwent liver transplantation at our center, and a review of the literature. RESULTS In patient 1, AML-M4 developed 19 months after transplant for cryptogenic cirrhosis. In patient 2, B cell acute lymphoid leukemia was diagnosed 10 months after liver transplant for fulminant hepatitis. Both patients had normal cytogenetics, and achieved complete remission with chemotherapy. In patient 3, acute monocytic leukemia-M3 with t(15;17) arose 18 months after transplant for hepatitis C cirrhosis. This patient received treatment with retinoic acid and chemotherapy, but developed a disseminated intravascular coagulation and died before completing therapy. No patient presented with chromosomal abnormalities commonly seen in secondary leukemia. The latency period to diagnosis after transplant was 10-19 months. CONCLUSIONS Acute leukemia, although rare after liver transplantation, should be considered in the differential diagnosis of hematological complications.

Abstract
The aim of this study is to analyze the impact of the recipient's disease severity on graft size requirements and outcome in adult-to-adult living donor liver transplantation. A limiting factor in adult-to-adult living donor liver transplantation has been adequacy of graft size. A minimal graft-recipient weight ratio (GRWR) of 0.8% to 1% has been suggested, without taking the recipient's disease into account. Forty adults underwent liver transplantation using left (n = 10; mean weight, 481 +/- 83 g) or right lobes (n = 30; mean weight, 845 +/- 182 g). We recorded graft survival, Child-Turcotte-Pugh score, and occurrence of small-for-size syndrome (poor bile production, prolonged postoperative prothrombin time, and cholestasis without ischemia markers). Small grafts were defined as GRWR of < or =0.85%. Large grafts were defined as GRWR greater than 0.85%. Six patients died within 6 months of transplantation (early patient survival rate, 85%); two patients died late of tumor recurrence. Among transplant recipients with normal liver function or Child's class A, there was no significant difference with the use of small (n = 6) or large (n = 9) grafts (graft survival rates, 83% v 88%, respectively; P =.65). Among patients with Child's class B or C, graft survival rates were 74% in recipients of large grafts (n = 19) and 33% in recipients of small grafts (n = 6; P =.023). Five of 6 patients with Child's class B or C who received small grafts developed small-for-size syndrome; 2 patients died (1 patient after retransplantation) and 3 patients survived (2 patients after retransplantation). Graft function and survival are influenced not only by graft size, but also by pretransplantation disease severity. GRWR as low as 0.6% can be used safely in patients without cirrhosis or in patients with Child's class A. Transplant recipients with Child's class B or C require a GRWR greater than 0.85% to avoid small-for-size syndrome and related complications.

Abstract
BACKGROUND Wilson's disease is an inherited disorder of copper metabolism characterized by reduced biliary copper excretion, which results in copper accumulation in tissues with liver injury and failure. Orthotopic liver transplantation (OLT) can be lifesaving for patients with Wilson's disease who present with fulminant liver failure and for patients unresponsive to medical therapy. The aim of this study is to review our experience with OLT for patients with Wilson's disease. METHODS Between 1988 and 2000, 21 OLTs were performed in 17 patients with Wilson's disease. Patient demographics, pre-OLT laboratory data, operative data, and early and late postoperative complications were reviewed retrospectively. One-year patient and graft survival was calculated. RESULTS Eleven patients had fulminant Wilson's disease; in six patients the presentation was chronic. Mean patient age at presentation was 28 years (range 4-51 years); mean follow-up was 5.27 years (range 0.4-11.4 years). Neurologic features of Wilson's disease were not prominent preoperatively and did not develop post-OLT except in one patient who developed acute neuropsychiatric illness and seizure. Renal failure, present in 45% of patients with fulminant Wilson's disease, resolved post-OLT with supportive care. One-year patient and graft survivals were 87.5% and 62.5%, respectively. Fifteen survivors have remained well with normal liver function and no disease recurrence. CONCLUSION Liver transplantation for hepatic complications of Wilson's disease cures and corrects the underlying metabolic defect and leads to long-term survival in patients who present with either acute or chronic liver disease. Acute renal failure develops frequently in patients with fulminant Wilsonian hepatitis and typically resolves postoperatively.

Abstract
BACKGROUND Risk factors for the development of posttransplant lymphoproliferative disease (PTLD), a major cause of morbidity and mortality after pediatric liver transplantation, are primary Epstein-Barr virus (EBV) infection and intensity of immunosuppression. The authors assessed monitoring of EBV replication and preemptive immunosuppression reduction in pediatric liver transplant recipients. METHODS The authors prospectively followed monthly EBV-quantitative competitive polymerase chain reaction to measure EBV replication in 23 patients who underwent liver transplant between July 1997 and November 1998. Preemptive immunosuppression reduction was instituted for significant EBV replication. Patients were followed up for at least 1 year and divided in two groups for analysis (group 1, pretransplant seronegative for EBV [13 patients]; group 2, seropositive for EBV [10 patients]). RESULTS In group 1, 9 of 13 patients had positive polymerase chain reaction results at a mean time of 22.4 weeks after transplantation. All but one of these patients were asymptomatic. In seven of nine patients, preemptive immunosuppression reduction was undertaken without development of PTLD or rejection. In two of nine patients, immunosuppression could not be continuously reduced, and both patients experienced low-grade and medically responsive PTLD. In no patient in group 2 did an EBV-positive viral load or PTLD develop. CONCLUSIONS Prospective longitudinal measurement of EBV by quantitative competitive polymerase chain reaction permits early detection of asymptomatic viral replication. Subsequent preemptive reduction of immunosuppression may prevent the progression to PTLD.

Abstract
BACKGROUND The relationship between primary renal disease and arterial wall changes in paediatric haemodialysis patients has been little studied. The aim of the present work was to determine the influence of primary renal disease on arterial wall pathology in uraemic paediatric patients. METHODS Twelve paediatric haemodialysis patients (seven girls, five boys) aged 11-17 years were included in the study. The primary renal diseases were urinary malformations in six patients (uropathy group) and acquired glomerular diseases (glomerulopathy group) in six patients. Age, sex distribution, duration of chronic renal failure, duration of haemodialysis, blood pressure, serum glucose, triglycerides, cholesterol, fibrinogen, calcium, phosphorus and parathyroid hormone levels were compared. Internal iliac artery samples were obtained at the time of related-donor renal transplantation. Artery samples were fixed in formaldehyde and sections were stained separately with haematoxylin and eosin, Orcein, Verhoef-van Gieson, and Masson trichrome. RESULTS Five arteries had fibrous or fibroelastic intimal thickening, medial mucoid ground substance and disruption of the internal elastic lamella. Two of these had microcalcification in the intimal layer; another two demonstrated atheromatous plaques; the remaining five were normal. These pathological changes were found in the arteries of all six patients with uropathy, whereas of the six patients with glomerulopathy only one had arterial changes (P<0.001). The duration of chronic renal failure was 4.8+/-1.9 years in the uropathy group and 2.2+/-1.2 in the glomerulopathy group (P<0.05). The two groups were comparable in terms of serum glucose, triglycerides, cholesterol, fibrinogen, calcium, and parathyroid hormone levels, presence of hypertension, sex distribution, and duration of haemodialysis. Plasma phosphorus and the calcium x phosphate product were higher in the uropathy group than in the glomerulopathy group (P<0.05). CONCLUSIONS This study demonstrated that pathological changes are common in the arteries of uraemic paediatric patients, and that calcification and atherosclerosis are integral to this disease process. In our study, these alterations were more common in the patients with uropathy. We speculate that the patients with uropathy are more prone to these alterations due to slower progression and a longer duration of renal insufficiency.

Abstract
Nearly 2000 liver transplants have been performed over the past 12 years at Mount Sinai, with a recent exponential growth in living donor surgeries. Living-donor liver transplantation has emerged as an important option for our patients with end-stage liver disease. We are only beginning to recognize fully the advantages that 'scheduled' liver transplantation can offer. In this era of severe cadaver organ shortages, living donation offers patients the option of liver replacement in a timely fashion, before life-threatening complications of hepatic failure and/or carcinoma progression prohibit transplantation. The next era of transplantation at Mount Sinai will bring significant increases in the number of transplants performed with living donors, with projections of over 50% of the total transplants each year expected to involve living donations. We are committed to offering this option while recognizing that donor safety remains paramount and cannot be overemphasized. Proper donor and recipient selection, as well as surgical experience are imperative to success with this technically demanding procedure. Recurrent disease after transplantation, particularly with hepatitis C, remains a challenge clinically. Further investigations into the pathogenesis of the rapid progression of recurrent hepatitis C need to be addressed. Living donor transplantation could be an important option for these patients and would allow timely transplantation and the potential for improved survival in patients with hepatocellular carcinoma.

Abstract
OBJECTIVE To summarize the evolution of a living donor liver transplant program and the authors' experience with 109 cases. SUMMARY BACKGROUND DATA The authors' institution began to offer living donor liver transplants to children in 1993 and to adults in 1998. METHODS Donors were healthy, ages 18 to 60 years, related or unrelated, and ABO-compatible (except in one case). Donor evaluation was thorough. Liver biopsy was performed for abnormal lipid profiles or a history of significant alcohol use, a body mass index more than 28, or suspected steatosis. Imaging studies included angiography, computed tomography, endoscopic retrograde cholangiopancreatography, and magnetic resonance imaging. Recipient evaluation and management were the same as for cadaveric transplant. RESULTS After ABO screening, 136 potential donors were evaluated for 113 recipients; 23 donors withdrew for medical or personal reasons. Four donor surgeries were aborted; 109 transplants were performed. Fifty children (18 years or younger) received 47 left lateral segments and 3 left lobes; 59 adults received 50 right lobes and 9 left lobes. The average donor hospital stay was 6 days. Two donors each required one unit of banked blood. Right lobe donors had three bile leaks from the cut surface of the liver; all resolved. Another right lobe donor had prolonged hyperbilirubinemia. Three donors had small bowel obstructions; two required operation. All donors are alive and well. The most common indications for transplant were biliary atresia in children (56%) and hepatitis C in adults (40%); 35.6% of adults had hepatocellular carcinoma. Biliary reconstructions in all children and 44 adults were with a Roux-en-Y hepaticojejunostomy; 15 adults had duct-to-duct anastomoses. The incidence of major vascular complications was 12% in children and 11.8% in adult recipients. Children had three bile leaks (6%) and six (12%) biliary strictures. Adult patients had 14 (23.7%) bile leaks and 4 (6.8%) biliary strictures. Patient and graft survival rates were 87.6% and 81%, respectively, at 1 year and 75.1% and 69.6% at 5 years. In children, patient and graft survival rates were 89.9% and 85.8%, respectively, at 1 year and 80.9% and 78% at 5 years. In adults, patient and graft survival rates were 85.6% and 77%, respectively, at 1 year. CONCLUSION Living donor liver transplantation has become an important option for our patients and has dramatically changed our approach to patients with liver failure. The donor surgery is safe and can be done with minimal complications. We expect that living donor liver transplants will represent more than 50% of our transplants within 3 years.

Abstract
Long-term renal function was compared in 49 liver recipients [25 patients received cyclosporin (CyA) and 24 patients received FK 506] followed for a period of 1 year. Creatinine (CR) and glomerular filtration rate (GFR) pretransplantation (pre-Tx) and at 1, 3, 5, and 12 months post-Tx were recorded, as well as incidences of hyperkalemia, post-Tx hypertension, and insulin-dependent diabetes mellitus (IDDM) in the two groups. At 1 year post-Tx, the mean Cr had risen from baseline by 56% and 60% in the FK and CyA groups, respectively; the mean GFR had dropped by 32% in FK patients and by 27% in CyA patients. Acute nephrotoxicity occurred in 7/25 CyA patients (2/7 required dialysis) and 9/26 FK patients (7/9 required dialysis; 2/7 were switched to CyA). None remained on dialysis at 3 months. Renal insufficiency persisted at 1 year in 7/16 patients with early toxicity (CyA, 4; FK, 3) and in 3 of the remaining 36 pts (P < 0.001). Hyperkalemia occurred in 4/25 CyA, and in 12/24 FK patients (P < 0.025), post-Tx hypertension occurred in 15 CyA, and 7 FK patients (P < 0.05), and IDDM occurred in 4 CyA and 7 FK patients (P = ns). FK 506 and CyA, thus, exerted similar chronic renal effects. Although acute renal insufficiency improved upon dose reduction, renal impairment was permanent in some cases.

Abstract
A 55-year-old Turkish man with a history of chronic hepatitis B for 35 years, presented with incapacitating fatigue and worsening shortness of breath. He was hospitalized several times because of hepatic encephalopathy. He underwent liver transplantation for a clinical diagnosis of Child's C cirrhosis complicated by hepatopulmonary syndrome. The explanted liver, however, was not cirrhotic and demonstrated features of hepatoportal sclerosis. Although treatment for hepatoportal sclerosis is relief of portal hypertension; in rare cases such as in this patient with liver failure, liver transplantation is indicated.

Abstract
The addition of daclizumab (a human immunoglobulin G1 monoclonal antibody that blocks interleukin-2 receptors on T lymphocytes) to mycophenolate mofetil (MMF) and steroids is a new option for initial immunosuppression in patients undergoing liver transplantation (LT) with impaired renal function. We evaluated the efficacy and safety of daclizumab in preventing rejection in 25 patients with impaired kidney function undergoing LT. Patients with serum creatinine (Cr) levels greater than 2 mg/dL immediately before LT were administered initial immunosuppression with daclizumab, 1 mg/kg, in addition to MMF, 2 g/d, and methylprednisolone. Tacrolimus was added after kidney function improved (when Cr levels improved by >25% of initial value). Daclizumab-treated patients were compared retrospectively with 2 other groups of patients who underwent LT with kidney impairment (Cr > 2 mg/dL): 56 patients were administered OKT3 induction, and 48 patients were administered low-dose tacrolimus. The incidence of rejection and infection (bacterial, fungal, and viral), need for preoperative and postoperative dialysis, Cr level immediately post-LT and at 3 months, and graft and patient survival were analyzed. There was no difference among the groups in 3-month Cr levels or the incidence of rejection or fungal or viral infection. The daclizumab group had fewer bacterial infections (n = 13) than the tacrolimus group (n = 28) and significantly fewer than the OKT3 group (n = 58; P =.006). Only 1 patient (4%) in the daclizumab group required dialysis post-LT versus 13 patients in each of the other groups (OKT3, 23.21%; P <.05; tacrolimus, 27%). In the daclizumab group, 2-year patient and graft survival rates were statistically significant compared with the low-dose tacrolimus group (89% and 81% v 73% and 69%, respectively; P =.06). There were no side effects related to daclizumab use, and all patients tolerated the drug well. In patients with impaired renal function before LT, daclizumab-based initial immunosuppression can be used safely to reduce the risk for infection and need for dialysis post-LT, with improved long-term graft and patient survival.

Abstract
BACKGROUND We aimed to review our experience with childhood lupus nephritis (LN) in respect to the analysis of the clinical and histopathological presentation of LN and prognostic factors affecting the kidney and patient outcomes. METHOD Forty-three children (39 girls, 4 boys) with biopsy-proven LN were included in the study. The mean age of the children was 12.0 +/- 2.8 years. Based on the renal histopathology and clinical presentation, patients were treated with oral prednisone, intravenous pulses of methylprednisolone or intravenous cyclophosphamide. The final clinical status was classified as follows: (1) renal and extrarenal remission; (2) clinically active renal disease, or (3) adverse outcome, i.e., end-stage renal failure (ESRF) or death. RESULTS The mean duration of follow-up was 7.2 +/- 2.8 years (1 month to 14.2 years). All 43 children had hematuria and 53.5% had proteinuria at admission. Fourteen children were in nephrotic status at the onset of disease. Class IV (diffuse proliferative) nephritis was observed in 29 patients as the most frequent histopathology (67.4%). The patients with class IV nephritis had a tendency to develop nephrotic syndrome, heavy proteinuria, increased Cr levels and persistent hypertension at initial evaluation. Thirty-two of 43 children (74.4%) were in renal remission at the last visit. Five-year kidney and patient survival rates from the time of diagnosis to the endpoints of ESRF or death were 83.7 and 90.7% respectively in the whole group while it was 75.9 and 86.2% respectively in the class IV group. Adverse outcome was significantly associated with the persistent hypertension, anemia, high serum Cr level, heavy proteinuria, nephrotic syndrome and class IV nephritis at presentation. CONCLUSION We can conclude that the prognosis of LN in children is primarily dependent on the histopathological lesions. Severity of the clinical renal disease at admission and presence of persistent hypertension are the main poor prognostic factors rather than age, gender, low C3 and C4 levels, ANA positivity and the treatment modalities in Turkish children.

Abstract
BACKGROUND Recurrence of hepatitis C after liver transplantation is an almost universal occurrence. T-cell derived cytokines have an important role in the development of liver damage associated with chronic hepatitis C, their post-transplant levels, however, have not been correlated with histologic recurrence of the disease. AIMS We sought to analyze levels of TNF-alpha, soluble IL-2 receptor, IL-4 and IL-10 at 1 month, 6 months and 1 year after transplantation in 27 patients undergoing transplantation for hepatitis C related end-stage liver disease. METHODS HCV RNA levels were monitored by a branched-chain DNA signal amplification assay. Diagnosis of recurrent hepatitis was based on 1-year protocol biopsies and on biopsies performed for liver enzyme elevations. RESULTS Recurrent hepatitis C was detected in 52% (n=14) of the 27 patients. HCV RNA levels rose over time in all patients regardless of histologic recurrence. TNF-alpha, and IL-4 levels, although elevated, did not show specific patterns over time or in correlation with recurrence. Similarly, the early elevation followed by a gradual decrease over the first year in the amount of soluble IL-2 receptor was not related to histologic recurrence. We observed a significant increase in circulating IL-10 levels over the first year in patients with biopsy-proven recurrence, while patients with no signs of histologic recurrence displayed increased, but steady levels. CONCLUSIONS These results suggest that while these cytokines are associated with post-transplant recurrence of hepatitis C, their production may be altered by additional factors.
