Objective To investigate the current status of treatment for patients with convulsive epilepsy in rural areas of Heilongjiang Province， China and the efficacy of phenobarbital in the treatment of epilepsy， and to evaluate the effect of the epilepsy prevention and management project in rural areas. Methods EpiData， EXCEL， and SPSS 19.0 were used for data entry， processing， and statistical description to analyze the current status of epilepsy treatment in rural areas， the dose of phenobarbital， and the frequency of seizures. In the epilepsy prevention and management project of Heilongjiang Province in 2015—2020， a total of 908 patients with convulsive epilepsy were enrolled in the phenobarbital treatment group， and after standardized treatment and follow-up management， 698 patients were followed up for at least 12 months. Results The gap rate of rural epilepsy treatment in Heilongjiang Province was 56.39%. After one year of standardized treatment， the frequency of seizures decreased from 23.86 times/year before enrollment to 3.11 times/year， showing a significant reduction. The response rate of epilepsy treatment was 68.19%， and the patients without previous standard treatment tended to have a better outcome than those who received standard treatment. Conclusion The current status of epilepsy treatment is not optimistic in rural areas of Heilongjiang Province， and there remains a large gap in epilepsy treatment. It is necessary to strengthen the training on the diagnosis and treatment of epilepsy among primary care physicians and implement the public education on the prevention and treatment of epilepsy， and since phenobarbital has a marked clinical effect in the treatment of epilepsy， it holds promise for further application in rural areas.
Phenobarbital

OBJECTIVE

Phenobarbital is an inductor of microsomal hepatic enzyme and used as choleretic for cholestatic liver disease to enhance bile flow. It is also used as a premedication for hepatobiliary scintigraphy (HIDA) scan to improve diagnostic accuracy for an obstructive liver disease. We reviewed the available literature on the use of Phenobarbital for treatment of cholestasis and its utility as a premedication for HIDA scan.

All published studies before June 30, 2023 that investigated the efficacy, effectiveness or safety of Phenobarbital in cholestatic jaundice and its effect on the accuracy of hepatobiliary scintigraphy in diagnosis of obstructive jaundice were included. Electronic databases were searched including MEDLINE via PubMed, Cochrane Library, medRxIV, BioRxIV, as well as the following registries for ongoing and completed trials: ClinicalTrials.gov (USA); ChiCTR.org. (China); and the WHO International Clinical Trials Registry Platform. We screened abstracts, reviewed full texts, and extracted relevant information on study design, settings, population and outcomes. There was no age and language restriction. Two reviewers independently rated the quality of included studies using: Joanna Briggs Institute critical appraisal tool for case reports, case series, and diagnostic accuracy; Newcastle – Ottawa Quality Assessment Scale for cohort studies, and Cochrane Risk of Bias for Randomized Trials. Risk of bias was appraised and GRADE certainty of evidence was judged. Pooled analysis was done using Stata 14 and reported as sensitivity and specificity.

Included were nine reports on Phenobarbital as treatment for cholestasis (one case report, five case series, one cohort and two randomized studies) and seven studies (four diagnostics, two cohorts, one randomized trial) on its use as a premedication for HIDA scan. The quality of case report and case series were considered fair; cohort studies as good; and diagnostic studies were included based on overall assessment. The randomized studies had some or high risk for bias due to concerns in randomization process, measurement of outcome, and risk in the selection of reported results.

There were 31 patients (16 adults and 15 children) from case reports and case series. Of the 16 adults, serum total bilirubin concentrations declined from 4 to 70% from baseline in 13 of 15 (87%) patients after Phenobarbital was given at 120 to 250 mg per day from 22 days to f ive months. Eleven of 14 with pruritus at onset also had improvement in intensity of itching. Of the 15 pediatric patients, ten (67%) showed a decrease from 10 to 60% of the baseline total bilirubin but not a normalization with Phenobarbital intake at a dose of 3 to 12 mg/kg/day from one to 21 months. Five of 14 children also had relief of itching after treatment.

Phenobarbital compared to Ursodeoxycholic acid had limited efficacy in reducing the bilirubin levels in neonates and young infants with cholestasis.

Phenobarbital compared to Ursodeoxycholic acid had limited efficacy in reducing the bilirubin levels in neonates and young infants with cholestasis.

Moderate certainty evidence showed that with Phenobarbital pretreatment, the hepatobiliary scan done on patients with neonatal cholestasis had 100% (CI 99.2, 100; I2 = 0.0%) sensitivity and 80.2% (CI 65.4, 92.1; I2 = 76.6%) specificity while no Phenobarbital pretreatment had 100% (94.9, 100; I2 = 0.0%) sensitivity and 89.5% (CI 77.0, 98.1; I2 = 11.4%) specificity. Adverse effects of Phenobarbital were drowsiness, lethargy, poor feeding, and irritability.

There was limited effectiveness of Phenobarbital in decreasing bilirubin levels in cholestatic liver disease. Moderate certainty evidence demonstrated that premedication with Phenobarbital did not improve the specificity of HIDA scan in the diagnosis of obstructive jaundice of infancy. Neurologic symptoms were observed with Phenobarbital intake.

PURPOSE: To determine the long-term efficacy of the anti-tumor necrosis factor (TNF) agents, infliximab (IFX) and adalimumab (ADA), in pediatric luminal Crohn's disease (CD) by performing a systematic literature review.METHODS: An electronic search was performed in Medline, Embase, and the Cochrane Library from inception to September 26, 2019. Eligible studies were cohort studies with observation periods that exceeded 1 year. Studies that reported time-to-event analyses were included. Events were defined as discontinuation of anti-TNF therapy for secondary loss of response. We extracted the probabilities of continuing anti-TNF therapy 1, 2, and 3 years after initiation.RESULTS: In total, 2,464 papers were screened, 94 were selected for full text review, and 13 studies (11 on IFX, 2 on ADA) met our eligibility criteria for inclusion. After 1 year, 83–97% of patients were still receiving IFX therapy. After 2 and 3 years the probability of continuing IFX therapy decreased to 67–91% and 61–85%, respectively. In total, 5 of the 11 studies subgrouped by concomitant medication consistently showed that the probabilities of continuing IFX therapy in patients with prolonged immunomodulator use were higher than those in patients on IFX monotherapy.CONCLUSION: This review of real-world evidence studies confirms the long-term therapeutic benefit of IFX therapy in diverse cohorts of children with luminal CD. Moreover, it supports the view that combination therapy with an immunomodulator prolongs the durability of IFX therapy in patients who previously failed to recover following first-line therapy. The limited number of time-to-event studies in patients on ADA prevented us from drawing definite conclusions about its long-term efficacy.

Gastroesophageal reflux disease (GERD) is a very common disease, and the prevalence in the general population has recently increased. GERD is a chronic relapsing disease associated with motility disorders of the upper gastrointestinal tract. Several factors are implicated in GERD, including hypotensive lower esophageal sphincter, frequent transient lower esophageal sphincter relaxation, esophageal hypersensitivity, reduced resistance of the esophageal mucosa against the refluxed contents, ineffective esophageal motility, abnormal bolus transport, deficits initiating secondary peristalsis, abnormal response to multiple rapid swallowing, and hiatal hernia. One or more of these mechanisms result in the reflux of stomach contents into the esophagus, delayed clearance of the refluxate, and the development of symptoms and/or complications. New techniques, such as 24-hour pH and multichannel intraluminal impedance monitoring, multichannel intraluminal impedance and esophageal manometry, high-resolution manometry, 3-dimensional high-resolution manometry, enoscopic functional luminal imaging probe, and 24-hour dynamic esophageal manometry, provide more information on esophageal motility and have clarified the pathophysiology of GERD. Proton pump inhibitors remain the preferred pharmaceutical option to treat GERD. The ideal target of GERD treatment is to restore esophageal motility and reconstruct the anti-reflux mechanism. This review focuses on current advances in esophageal motor dysfunction in patients with GERD and the influence of these developments on GERD treatment.

OBJECTIVE: To investigate the efficacy of motion-correction algorithm (MCA) in improving coronary artery image quality and measurement accuracy using an anthropomorphic dynamic heart phantom and 256-detector row computed tomography (CT) scanner. MATERIALS AND METHODS: An anthropomorphic dynamic heart phantom was scanned under a static condition and under heart rate (HR) simulation of 50–120 beats per minute (bpm), and the obtained images were reconstructed using conventional algorithm (CA) and MCA. We compared the subjective image quality of coronary arteries using a four-point scale (1, excellent; 2, good; 3, fair; 4, poor) and measurement accuracy using measurement errors of the minimal luminal diameter (MLD) and minimal luminal area (MLA). RESULTS: Compared with CA, MCA significantly improved the subjective image quality at HRs of 110 bpm (1.3 ± 0.3 vs. 1.9 ± 0.8, p = 0.003) and 120 bpm (1.7 ± 0.7 vs. 2.3 ± 0.6, p = 0.006). The measurement error of MLD significantly decreased on using MCA at 110 bpm (11.7 ± 5.9% vs. 18.4 ± 9.4%, p = 0.013) and 120 bpm (10.0 ± 7.3% vs. 25.0 ± 16.5%, p = 0.013). The measurement error of the MLA was also reduced using MCA at 110 bpm (19.2 ± 28.1% vs. 26.4 ± 21.6%, p = 0.028) and 120 bpm (17.9 ± 17.7% vs. 34.8 ± 19.6%, p = 0.018). CONCLUSION: Motion-correction algorithm can improve the coronary artery image quality and measurement accuracy at a high HR using an anthropomorphic dynamic heart phantom and 256-detector row CT scanner.

Canine MDR1 gene mutations produce translated P-glycoprotein, an active drug efflux transporter, resulting in dysfunction or over-expression. The 4-base deletion at exon 4 of MDR1 at nucleotide position 230 (nt230[del4]) in exon 4 makes P-glycoprotein lose function, leading to drug accumulation and toxicity. The G allele of the c.-6-180T>G variation in intron 1 of MDR1 (single nucleotide polymorphism [SNP] 180) causes P-glycoprotein over-expression, making epileptic dogs resistant to phenobarbital treatment. Both of these mutations are reported to be common in collies. This study develops a more efficient method to detect these two mutations simultaneously, and clarifies the genotype association with the side effects of chemotherapy. Genotype distribution in Taiwan was also investigated. An oligonucleotide microarray was successfully developed for the detection of both genotypes and was applied to clinical samples. No 4-base deletion mutant allele was detected in dogs in Taiwan. However, the G allele variation of SNP 180 was spread across all dog breeds, not only in collies. The chemotherapy adverse effect percentages of the SNP 180 T/T, T/G, and G/G genotypes were 16.7%, 6.3%, and 0%, respectively. This study describes an efficient way for MDR1 gene mutation detection, clarifying genotype distribution, and the association with chemotherapy.
