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.
