Objective To assess the efficacy and safety of ketogenic diet(KD) on refractory epilepsy in children.Methods KD treatment was designed to observe the effects for 12 weeks.Totally 22 children with 16 boys and 6 girls were enrolled in the study.The epileptic syndromes included infantile spasms(13 cases),Lennox-Gastaut syndrome(4 cases),Dravet syndrome(2 cases),and the unclassified(3 cases).The KD was prepared according to the modified Johns Hopkins regimen.Urinary ketones were measured every day to ensure that ketosis state and parents′ diaries were kept to find out when it started to work and the change of seizure frequency.Effects of KD was evaluated by Engel standard.Blood chemistry was done at baseline,4 weeks and 12 weeks to analyze the effects of KD on metabolism.Side effects were monitored and treated.Results All cases completed the KD regimen for at least 2 weeks,19 cases for at least 4 weeks,and 10 cases for at least 12 weeks.Sixteen out of 22 children experienced the seizure reduction within 3 weeks(1-15 d),especially in the first week,and seizure free appeared within 5 weeks(1-32 d) in 8 cases.Overall,the diet achieved the seizure-free in 36.4%(8/22 cases) and an over 90% of seizure frequency reduction in 22.7%(5/22 cases).The efficacy of KD seemed not correlated with the sex,age,etiopathogenisis,and syndromes and so on.Blood chemistry suggested a normal range of glucose level at 4 weeks,though higher than that at the baseline.The blood triglyceride and total cholesterol level at 12 weeks increased strikingly,even beyond the normal range compared with the baseline.The side effects mainly including transient gastrointestinal symptoms and metabolic disturbances were mostly tolerable.Conclusions KD is probably a feasible therapy on refractory epilepsy in children,with quick and high efficacy and few side effects.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

OBJECTIVEClinical manifestations of opsoclonus-myoclonus syndrome (OMS) in children were summarized and analyzed and the clinical features and therapeutic approaches to OMS were investigated in order to improve its diagnosis and management.

METHODSClinical information on features and management of 6 cases with OMS inpatients being followed up from 2006 to 2007 were collected and analyzed.

RESULTSAmong the 6 cases, one was male and the other five were female. The age at the onset ranged from 12 to 26 months (average 21.0 months). Four of them had history of prior infection. The symptoms were opsoclonus, myoclonus, ataxia, sleep disturbances and behavioural problems in the 6 cases. Urinary DL-3-methoxy-4-hydroxy-acid amygdalin (VMA) was positive in 1 case. Abdominal B-mode ultrasound showed a mild hepatomegaly in 4 cases. The EEG showed abnormal findings such as slow background activity in 3 cases. Epileptiform discharges were found in none of the patients. MRI showed a high signal in medial longitudinal fasciculus and tectospinal tract on T2-weighted image in 1 case. Computerized tomography found L3-4 arachnoid cysts in 1 case and was normal in the others. Adrenocorticotropic hormone (ACTH) was given to all these patients and was effective in all during acute stage. In 2 cases the disease relapsed during follow-up stage.

CONCLUSIONOMS is a rare neurological condition with opsoclonus, myoclonus, ataxia, sleep disturbances and behavioral problems, which might relapse easily and is associated with adverse neurological outcome. ACTH therapy is effective in management of OMS.

A(p.G888S)were detected in POLG1 gene.Sequence analysis of parental blood DNA revealed that her father carried L83P and her mother carried G888S.Conclusions The characteristics of clinical manifestation,electrophysiology,pathology and POLG1 gene mutation of the patient were highly consistent with Alpers syndrome.The prominent white matter change and increased immunological factors in CSF were first reported in Alpers syndrome.Alpers syndrome should be considered for those patients whose liver function were severely impaired after exposure to valproic acid.

OBJECTIVETo analyze the indication and choice of operation technique for duodenum-preserving resection of pancreatic head.

METHODSThe Clinical material of the 22 patients who received duodenum-preserving resection of pancreatic head (DPPHR) from January 2001 to January 2006 was analyzed. Of the 22 cases, 8 cases presented with mucinous cystadenoma, 2 cases with mucinous cystadenocarcinoma, 4 cases with solid-pseudopapillary tumors, 2 cases with pancreatic endocrine tumors, 4 cases with chronic pancreatitis, 1 case with lymph epidermis cyst, 1 case with serous cystadenoma. The indication, choice of operation technique of DPPHR and the prevention and management of the post-operative complications were investigated.

RESULTSNo patient died of the operation. Three cases (13.6%) developed pancreatic fistula after the operation, 1 case (4.5%) developed biliary fistula, 1 case (4.5%) developed abdominal infection and 2 cases of duodenal fistula occurred (9.1%).

CONCLUSIONSDPPHR retains the continuity of stomach, duodenum and biliary ducts. The operation is safe and it reduces wounds and excision scope. This procedure can be used in benign and low malignant lesions in the head and neck of the pancreas.

OBJECTIVETo explore the expression and clinical significance of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients.

METHODSThe expression of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients were detected with reverse transcription realtime PCR.

RESULTSExpression of MUC4 mRNA was not detected in the peripheral blood mononuclear cells of chronic pancreatitis patients and normal healthy people, but was observed in those of pancreatic cancer patients. The positive expression rate of MUC4 mRNA in pancreatic cancer patients was 60%, which was significantly higher than those of chronic pancreatitis patients and normal healthy people (P < 0.01). The positive expression rate of MUC4 mRNA increased with the development of clinical stage, and the positive expression rate in stage of II - IV (TNM system) was 76.92%, which was significantly higher than that of I - II stage (P < 0.01).

CONCLUSIONSExpression of MUC4 mRNA is highly correlated with the clinical stage in pancreatic cancer patients. Detecting the expression of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients may be helpful for the early diagnosis and differential diagnosis.

?? [Abstract]? Objective? To deeply explore the care needs in parents of children with congenital pseudarthrosis of the tibia (CPT) during Ilizarov fixation. Methods? Totally 10 parents of CPT children during Ilizarov fixation hospitalized in the Department of Orthopedics, Hu'nan Children's Hospital between March and December 2017 were selected using purposive sampling and received semi-structural interview. Colaizzi phenomenological methods were used to analyze the data. Results? Totally 4 themes were refined, including informational support needs (needle way care, functional exercise and feeding), psychological support needs, economic support needs, and children's educational support needs. Conclusions? The parents of CPT children during Ilizarov fixation have many care needs. Nursing workers should pay attention to their needs and take targeted measures to accelerate the postoperative recovery of children.

OBJECTIVETo investigate the clinical, neurophysiologic characteristics and therapeutic considerations of epileptic negative myoclonus (ENM) in atypical benign partial epilepsy of childhood (ABPE).

METHODSVideo-EEG monitoring with outstretched arm tests were carried out in 17 patients, and 9 of them were examined with simultaneous electromyography (EMG). The ENM manifestations, electrophysiologic features and responses to antiepileptic drugs (AED) were analyzed.

RESULTSSeventeen patients were diagnosed as having benign childhood epilepsy with centrotemporal spikes (BECT) during the early course of the disease and were treated with AED. During the course of the disease, hand trembling, objects dropping, head nodding and instability during standing might be clues for ENM occurrence. ENM had been confirmed in our patients by outstretched arm tests during video-EEG recording. The ictal EEG showed that high-amplitude spikes followed by a slow wave over the contralateral motor areas. This was further confirmed by time-locked silent EMG in 9 patients. During ENM occurrence or recurrence, the habitual seizures and interictal discharges were exaggerated. Atypical absence seizures also occurred in 6 patients. The alteration of therapeutic options of AED relating to ENM appearance in some patients included the add-on therapy with carbamazepine (CBZ), oxcarbazepine, phenobarbital, or withdrawal of valproate (VPA). ENM was controlled in most cases by using VPA, clonazepam (CZP) and corticosteroid with different combination.

CONCLUSIONENM could occur during the course of ABPE. Outstretching arm tests during video-EEG monitoring in combination with EMG was essential to confirm ENM. The ENM occurrence was always associated with the frequency increasing of habitual seizures and the aggravation of interictal discharges. Some AED such as CBZ might induce ENM. VPA, benzodiazepines and corticosteroid with different combination were relatively effective in treatment of ENM.

OBJECTIVEX-linked adrenoleukodystrophy (X-ALD) is the most common inherited disorder of peroxisomal metabolism which is characterized by demyelination of central nervous system, impaired adrenal cortex and abnormal accumulation of very long chain fatty acids in body fluid and tissues. In this study, the clinical features and the genotype-phenotype relationship were investigated so as to help early diagnosis.

METHODSClinical data of 89 Chinese patients with X-ALD were analyzed and mutation spectrums in 53 of the patients were investigated by polymerase chain reaction and DNA sequencing.

RESULTSOf the 89 cases, 60 (67.4%) had childhood cerebral ALD (CCALD, mean age of onset was 6.5 years, range 2 - 10 years), 18 (20.2%) had adolescent cerebral ALD (ACALD, mean age of onset 12.1 years, range 11 - 19 years), 7 (7.9%) had adrenomyeloneuropathy (AMN, mean age of onset 23 years, range 6 - 39.5 years), and two cases were asymptomatic and another 2 had simple Addison's disease only. CCALD was the most common and severe phenotype, visual impairment was the most common initial symptom in CCALD and ACALD patients. Twenty four cases (63%) in whom hydrocortisone and ACTH were measured showed adrenal insufficiency. Forty five different mutations were identified in 53 patients. Missense mutations were the most common. No hotspot mutation was found in these patients and 1415delAG, the most frequent mutation found worldwide seemed not to be the real "hotspot" in these Chinese patients. The same phenotype may be due to diverse genomic mutations. A single mutation may result in different phenotypes even within a family.

CONCLUSIONThe phenotype distribution, initial symptom and gene mutation spectrum of Chinese patients may not be completely consistent with those in other countries. The clinical phenotype of the disease had no definite relationship with the nature of gene mutations.

OBJECTIVEThe congenital muscular dystrophies (CMD) are a clinically and genetically heterogeneous group of neuromuscular disorders with progressive muscle wasting and weakness that begin during neonatal or early infantile period. To study the clinical diagnosis, immunohistochemical feature and follow-up information of CMD, data of 8 cases with CMD were analyzed.

METHODSImmunohistochemical features of biopsied muscle specimens were summarized and analyzed by using anti-laminin alpha2 (merosin), anti alpha-dystroglycan (alpha-DG) and anti beta-dystroglycan (beta-DG) antibodies.

RESULTSThese patients mostly presented at birth or during the first six months of life with muscle weakness, hypotonia, contractures, and feeding difficulty or respiratory dysfunction. Hematoxylin-eosin staining of skeletal muscle specimens from these patients showed typical characteristics of CMD. Differences in fiber size, with predominantly small and round fibers, and dense connective tissue infiltration were seen. Four of the 8 patients were merosin-stain negative, which might be due to primary merosin deficiency. T2-weighted magnetic resonance imaging of the brain shows abnormalities of the white matter. Four cases were merosin-stain positive, and two of them also had hypoglycosylation of alpha-dystroglycan. Two patients had mental retardation. One of them had optic nerve atrophy and abnormal brain structure.

CONCLUSIONSTwo types of CMD were present in our group. Merosin-deficient congenital muscular dystrophy (congenital muscular dystrophy 1A, MDC1A) was more common, accompanied by abnormalities of the white matter. "Alpha-dystroglycanopathy" could be seen in merosin-positive cases.
