Abstract
Hepatic myelopathy (HM) is a rare neurological complication in the end stage of many liver diseases and is characterized by bilateral spastic paraparesis without sensory and sphincter dysfunction. It occurs owing to metabolic disorders and central nervous system dysfunction associated with cirrhosis. Without timely and effective clinical intervention, the prognosis of these patients is devastating. Although liver transplantation (LT) is an effective treatment for HM, the prognosis of these patients remains unsatisfactory. Early recognition and diagnosis of this disease are essential for improving patient prognosis. Here, we report a case of hepatitis B virus-associated decompensated cirrhosis with HM. The patient recovered well after LT. We also summarize the clinical characteristics and post-transplant outcomes of 25 patients with HM treated by LT through 2023, including this case.

Abstract
OBJECTIVES Chronic disorders may negatively affect people's learning status, marital status, occupational life, and social life. Liver transplant is the only curative treatment for chronic liver diseases. This study was undertaken to evaluate the psychosocial effects of liver transplant in adult patients who had undergone liver transplant during the pediatric period compared with psychosocial facts in the general population. MATERIALS AND METHODS We retrospectively reviewed adult patients (>18 years of age) who had received liver transplant as children. We compared sex, age at the time of transplant, current age, type of donor, graft survival status, marital status, age at first delivery, number of children, educational status, and occupational status in the study population versus the general (normal) population. To compare the liver transplant patients included in the study with the general population correctly, we used data from the Turkish Statistical Institute. RESULTS Among 77 liver transplant patients included in our study, the mean age at transplant was 10.9 years (range, 0.5-16 y) and the mean age at the time of the study was 25.2 years (range, 18-42 y). Of the patients, 61 (79.2%) were single and 16 (20.8%) were married. Patients in the study population married at a younger age than the general population (25.5 vs 28.1 y for men, 24.3 vs 25.4 y for women). Of 16 married patients, 9 (56.2%) had a healthy child or children. The percentage of patients who graduated from higher education or were continuing their higher education process was higher in our study population than in the general population (36.3% vs 22.8%). Among our study population, 37 patients (48%) were workers. CONCLUSIONS Liver transplant had no negative effects on the social, educational, and professional lives among adults in our study who received transplants in the pediatric period.

Abstract
INTRODUCTION There is paucity of data on neurological complications (NCs) and its predisposing factors, in pediatric liver transplant (PLT) recipients. METHODS Records of seventy-one children who underwent LT between October 2018 and November 2019 were reviewed. Patients were categorized into group A: with NC and group B: without NC in the post-LT period. Various risk factors contributing to NC were studied. RESULTS In total, 15 (21.1%) had NC (group A) and 56 (78.9%) had no NC in the post-LT period. NC included cerebrovascular accident (n = 1), seizures (n = 5; 4 generalized, 1 focal), central pontine myelolysis (CPM) (n = 1), diaphragmatic palsy (n = 2), peripheral neuropathy (n = 1), extrapyramidal movements (n = 3), and encephalopathy beyond 96 h (n = 2). The median onset of NC was at 8.5 days post-LT (1-58 days). Ten (66.7%) patients in group A had grades 2-4 hepatic encephalopathy (HE) prior to LT. Eight (14.3%) patients in group B also had pre-LT neurological issues including HE in six, epilepsy and spastic diplegia in one each. On univariate analysis, pre-existing HE, high PELD/MELD score, pre-LT ventilation, pre-LT infection, higher day 1 post-operative bilirubin (all p < .05), and higher tacrolimus were found to predict post-operative NC whereas on multivariate analysis, pre-LT HE was the only predictive factor. Median follow-up was 15.5 months. Four patients died in each group (survival log-rank p = .369). All the surviving patients in group A (n = 11) fully recovered from the NC. CONCLUSION Pre-transplant HE was the single most significant predisposing factor for post-LT neurological complications.

Abstract
pLT is a highly standardized therapy for children with end-stage liver disease and liver-based metabolic diseases. However, NCs after transplantation occur and especially younger children are considered as more vulnerable and susceptible to NCs. Up to now, detailed data particularly for the very young age group do not exist. We therefore retrospectively studied NCs in children after pLT under age of 24 months. Forty children aged between 19 days and 22 months were evaluated according to type of NC and potential risk factors. NCs occurred in 8/40 patients (20%). All experienced new-onset seizures and in 1/6 surviving patients, seizures evolved into epilepsy. Other NCs were intracerebral abscess (1/8 patients) and subdural hemorrhage (1/8 patients). The overall 3-year mortality rate was 10% (4/40 patients). Significant risk factors for NCs and therefore seizures were HAT (P = 0.020), total surgery time (P = 0.009), retransplantation (P < 0.001), period of catecholamine therapy (P = 0.024), period of mechanical ventilation (P = 0.014), and period of sedation (P = 0.010). Our study is the first to provide detailed information on NCs after pLT in children under 24 months of age. The incidence of NCs in this particular group of very young patients was not increased compared to previously published data of children of all ages. Main NC was new-onset seizure. In the surviving infants, prognosis of seizure was excellent and the risk of developing epilepsy was low. Even more, the occurrence of NCs did not significantly affect mortality or survival in this particular age group.

Abstract
NCs occur commonly after solid organ transplantation and affect 15%-30% of liver transplant recipients. The aim of this retrospective study was to evaluate the type and incidence of neurologic events in pediatric patients following LT. Between May 2006 and June 2015, 242 patients (118 females, 124 males) requiring LT for different etiologies at the İnönü University Liver Transplantation Institute were included. The incidence, types, and risk factors of NCs that occurred following LT were evaluated retrospectively. Neurologic events occurred in 57 (23.5%) of the patients. Early NCs were encephalopathy (12.4%), seizures (11.5%), and PRES (7%). Of 57 patients, five (8.7%) experienced NCs at least 1 month after LT; these late NCs included tremor, headaches, encephalopathy, ataxia, and neuropathy. The psychiatric symptoms after LT were noted in 42 patients (17.4%). The mortality rate after LT in those with or without neurological events was not significantly different (P=.73). There was a high incidence of serious neurologic events after LT. The major neurologic manifestation in our patients was encephalopathy followed by seizures.

Abstract
The cause of post-transplant CNI-NCs is multifactorial and not ascribed solely to CNI toxicity. A total of 90 children (aged <20 years) who underwent LDLT were evaluated to investigate the predictive factors associated with CNI-NCs. Twelve patients (13.3%) developed CNI-NCs after LDLT (age range, 2-15 years). The symptoms of CNI-NCs were seizures, VD, and stupor. The median onset of CNI-NCs was 10 days (range, 5-30 days) post-transplant. In the univariate analysis, higher recipient age at LDLT, donor age and recipient's BW, lower actual GV/SLV and TAC dosage/BW, and higher mean T-Bil and sodium level for 7 days after transplantation were independently significantly associated with TAC-NCs. Multivariate analysis showed that the T-Bil level in the first week after LDLT was the only significant independent predictive factor for TAC-NCs (HR, 1.588; 95% CI, 1.042-2.358; P=.031). In conclusion, CNI-NCs occurred most frequently in children over 5 years and were associated with hyperbilirubinemia for 7 days post-transplant, regardless of TAC levels. The transplant team should refer to a neurologist to define the diagnosis and to collaborate to resolve the neurological problems.

Abstract
Despite the improved outcomes of LT, post-operative NCs remain a significant cause of morbidity and mortality. The aim of the study was to identify the incidence of and risk factors for NCs in children who underwent LT. The medical records of pediatric patients who underwent LT at Asan Medical Center Children's Hospital between January 1994 and December 2010 were retrospectively analyzed. The onset and types of NC and pretransplant variables associated with NC were evaluated. We identified 190 children (85 boys [44.7%], 105 girls [55.3%]) of mean age 4.1 ± 4.7 yr, who underwent LT. Forty-six NCs occurred in 41 (21.6%) patients after LT, the most common being seizures (n = 13, 28.3%) and encephalopathy (n = 10, 21.7%). Of the 46 NCs, 24 (52.2%) occurred within three months after LT. Multivariate analysis showed that primary liver disease, preoperative neurological problems, preoperatively higher serum creatinine concentration, and graft failure were significant risk factors for NCs. The survival rate was significantly lower for patients with NCs than for those without (p < 0.001). NCs after pediatric LTs were common and associated with a higher mortality rate in our study. Close monitoring and appropriate risk management may improve the long-term outcomes of pediatric patients who undergo LT.

Abstract
OBJECTIVE We studied neurological complications (NCs) after liver transplantation (LT) in children. METHODS We performed an institutional review board-approved retrospective review of patients with LT ≤21 years during a period of 30 years (1980-2010). NCs were classified as early (within 3 months post-LT) and delayed (beyond 3 months post-LT). RESULTS Of 65 children with LT, 20 (30.7%) had NCs; 16 were girls. Mean age was 11.8±5.9 years. Early NCs were found in 13.8% (9/65) of the patients: seizures in 7 and encephalopathy in 2. Abnormal neuroimaging findings were posterior reversible leukoencephalopathy syndrome (1), intracranial hemorrhage (1), mild cerebral edema (1), and bilateral basal ganglia T1W hyperintensities in magnetic resonance imaging (1). On follow-up, there were 3 deaths (unrelated to NCs). One with intracranial hemorrhage had residual hemiparesis and was taking a long-term antiepileptic drug. Late NCs are found in 16.9% (11/65) of the patients: seizures in 4, headache in 4, encephalopathy in 3 (1 had seizures in addition), and paresthesias caused by possible small-fiber neuropathy in 1. Abnormal neuroimaging findings were hypoxic-ischemic encephalopathy (1), encephalomalacia caused by old hemorrhage (1), and hyperintensity of the posterior periventricular white matter in magnetic resonance imaging (1). On follow-up, all of the patients survived; 1 had papilledema with secondary optic atrophy requiring optic nerve sheath fenestration and 1 needed long-term antiepileptic drug. CONCLUSIONS NCs are common in children after LT, seizures being the most common. In contrary to the previous studies, we found delayed complications more often than early complications. Early detection and appropriate management of NCs is important.

Abstract
With the aim of guiding choice of the best imaging modality for specific clinical conditions, we retrospectively evaluated neuroradiological findings in pediatric liver transplant recipients with neurological complications. Computed tomography (CT) was used to examine 31 patients with acute neurological symptoms after liver transplantation, and magnetic resonance imaging (MRI) was used for 35 such patients. A total of 16 patients belonged to both groups. Headache was the most common symptom in patients with computed tomography; seizure was most common among patients with magnetic resonance imaging. Magnetic resonance imaging detected additional abnormalities in 5 patients presenting with seizures whose computed tomography results were normal or insufficient to explain the clinical picture. In conclusion, liver transplant recipients with seizure should undergo magnetic resonance imaging emergently when possible; omitting computed tomography. Choice of imaging modality should be directed by nature of symptoms and time interval between transplantation and symptom onset.

Abstract
The literature contains very little documentation on neurologic complications in liver transplant recipients for Wilson's disease. We retrospectively reviewed 17 consecutive cases of pediatric liver transplantation for the hepatic form of Wilson's disease to assess the types of neurologic complications that occurred, the incidence of those problems, and associated factors in this patient group. The patients were 12 boys and 5 girls; indications for liver transplantation were fulminant hepatic failure in 3 patients and chronic hepatic failure in 14 patients. Neurologic complications were observed in 10 of the 17 patients as 16 episodes. The most common neurologic complications were seizure (7 episodes in 6 patients) and sudden-onset headache (5 episodes in 4 patients). Tacrolimus was identified as the only possible cause of headache in 3 episodes. Encephalitis was the cause in 1 and intracranial hemorrhage was the cause in the other headache episode. We also noted 1 episode of tremor, 1 episode of acute dystonic reaction, 1 episode of diffuse encephalopathy, and 1 episode of common peroneal nerve palsy. Immunosuppressive agents were the primary cause of 12 of the 16 episodes of neurologic complications. Uremia with hypertension, compression of the right common peroneal nerve, encephalitis, and intracranial hemorrhages attributable to coagulopathy caused 1 neurologic episode each. Neurologic complications in patients with the hepatic form of Wilson's disease were frequent during the first 30 days after pediatric liver transplantation but did not affect survival. Transplantation teams should be aware of the high incidence of neurologic complications in pediatric patients with the hepatic form of Wilson's disease.

Abstract
Neurologic complications (NCs) are a significant cause of morbidity and mortality in patients who undergo liver transplantation (LT). The aim of this study was to evaluate the incidence and type of NCs and associated factors in pediatric LT patients. We retrospectively reviewed NCs in the medical records of 40 consecutive infants, children, and adolescents who underwent LT at our institution. The subjects consisted of 23 boys and 17 girls (median age, 8.5 +/- 0.85 yr; range, 11 months to 17 yr). The indications for LT were Wilson's disease in 10 patients, fulminant hepatic failure (FHF) in nine, and other types of chronic liver disease in 21. NCs were found in 14 patients (35%). Those 14 individuals experienced a total of 16 episodes of NCs (two separate episodes in two of the patients). The most common NCs were seizure (seven episodes in six patients) and posterior leukoencephalopathy syndrome (PLES; five episodes in four patients). Seizure was the presenting symptom in three episodes of PLES. Two episodes of diffuse encephalopathy were observed in two patients, and two episodes of psychiatric symptoms occurred in two patients. We also noted one episode of tremor in one patient, one episode of acute dystonic reaction in one patient, and one episode of headache in one patient. Patients with Wilson's disease had a higher incidence of NCs (60%) than did patients without Wilson's disease (26.7%); however, this difference was not significant. The incidence of NCs was 44% in patients with FHF and 35% in those without FHF. That difference also was not significant. Immunosuppressive agents were the primary cause of 13 of the 16 episodes of NC. Uremia with hypertension, hypoxia, and hypomagnesemia caused one neurologic episode each. NCs, which are frequent in the first 30 days after pediatric LT, did not affect survival in this group. NCs were reversed by the discontinuation or reduction of immunosuppressive agents in 12 episodes, correction of hypomagnesemia and the reduction of immunosuppressive agents in one episode, and the correction of uremia and hypertension in one episode. Refractory epilepsy developed in one patient, and death unrelated to NCs occurred in one. The mortality rate was 7.1% (n = 1) in patients with NCs and 15.4% (n = 4) in those without NCs (p = 0.64). NCs are an important complication after LT. It is essential that each transplantation team collaborate with pediatric neurologists to ensure the rapid and accurate diagnosis of NCs in infants, children, and adolescents after LT and to prevent the delay of appropriate treatment.

Abstract
Children with end-stage liver disease have been found to have cognitive deficits. The aim of this study was to examine whether cholestatic jaundice causes spatial deficits in rats and if these cognitive deficits are reversed by biliary drainage. Rats were randomly divided into three groups. In the first group, the bile duct was ligated for 3 weeks (BDL group); in the second group, the proximal bile duct was ligated with a Broviac CV catheter for 2 weeks followed by a tube bilioduodenostomy (TBD group); in the third group, a sham operation was performed (SHAM group). All the surviving rats were assessed for spatial learning and memory (a major cognitive function in rats) by the Morris water maze task about 3 weeks after the first operation. Blood was aspirated by cardiocentesis and assayed for total bilirubin, albumin, ammonia, and hemoglobin levels on the day following the water maze task. During the four consecutive acquisition trial days of the Morris water maze, jaundiced rats (BDL group) had a significant longer latency to escape than the SHAM group ( p < 0.05). Rats that underwent biliary decompression for 1 week (TBD group) showed improved status of the spatial deficit, as they required less time to reach the escape platform, approaching the performance of the SHAM group. The BDL group had a significantly higher serum ammonia level, higher bilirubin level, and lower hemoglobin level than the other two groups. After biliary decompression for 1 week, the serum albumin concentration in the TBD group still did not return to the level of the SHAM group. The results of this study suggest that long-term cholestasis results in spatial memory deficits in rats that correlate with anemia and hyperbilirubinemia encephalopathy. Early biliary decompression of obstructive jaundice improves spatial memory deficits, possibly related to the recovery of the serum ammonia and hemoglobin levels.

Abstract
Many liver transplant recipients are now reaching survival beyond 5 years from the liver transplant procedure, and many others are alive more than a decade from acquiring their new liver. Orthotopic liver transplant recipients enjoy the benefits of normal liver function, but a variety of metabolic and other medical problems often develop that require diagnosis and adequate management. These problems include hyperlipidemia, obesity, diabetes mellitus, renal disfunction, arterial hypertension, bone disease and neuropsychiatric syndromes. The gastroenterologist, internist, or local family physician is frequently called on to identify and treat these postoperative complications in conjunction with physicians at the transplant center.

Abstract
Ischemic stroke is an uncommon, but significant cause of disability in childhood. Children with strokes present with predictable deficits as adults do; however, fever and seizures at stroke onset are more common in children than in adults. Strokes in children have diverse etiologies and require extensive evaluation. Etiology remains obscure in up to half of the patients. Prognosis in childhood stroke is not benign and up to 50% of pediatric stroke patients have chronic sequelae. Emerging therapies may alter prognosis in certain populations of children at risk for stroke, but more research is necessary.
