1.Current status of epilepsy treatment and efficacy of phenobarbital in rural areas of Heilongjiang Province, China
Journal of Apoplexy and Nervous Diseases 2025;42(1):52-55
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.

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.
METHODSAll 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.
RESULTSIncluded 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.
CONCLUSIONThere 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.

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.

9.Interpretation of the Results of Arterial Stiffness Tests
Korean Journal of Medicine 2019;94(6):500-510
Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Early detection of subclinical atherosclerosis is important for reduction of cardiovascular risk. However, the current diagnostic strategy, which focuses on traditional risk factors or the use of risk scoring, is unsatisfactory. Arterial walls thicken and stiffen with age, a process known as arteriosclerosis. There is a close interaction between arterial stiffness and atherosclerosis. Increased luminal pressure and shear stress caused by arterial stiffening result in endothelial dysfunction, accelerate the formation of atheromas, and stimulate excessive collagen production and deposition in the arterial wall. Carotid intima-media thickness (CIMT) has been shown to predict cardiovascular risk in many large studies. However, there is controversy regarding the value of CIMT for prediction of cardiovascular risk because of differences in study design, specifically with respect to CIMT measurements. Pulse wave velocity (PWV) is the most widely used measure of arterial stiffness; measurement of PWV is simple, non-invasive, and reproducible. Many clinical studies and meta-analyses have shown that PWV has predictive value in cardiovascular disease beyond traditional risk factors, both in the general population and in patients with various diseases. Brachial pressure has been a poor surrogate for aortic pressure for more than 50 years. However, recent studies have shown a closer relationship between central blood pressure and intermediate cardiovascular phenotypes or cardiovascular target organ damage, compared to the respective relationships with brachial blood pressure. Considering the non-invasiveness and ability to collect multiple types of clinical data, measurement of CIMT, PWV, and central blood pressure may be useful to identify patients at high risk for development of cardiovascular disease.

10.Aortoiliac Occlusive Disease as a Cause of Allograft Kidney Dysfunction and Refractory Hypertension
Kosin Medical Journal 2019;34(2):168-172
Aortoiliac occlusive disease (AIOD), especially proximal to the transplant artery, in kidney transplant patient activates the renin-angiotensin-aldosterone system by limiting graft renal perfusion and causes symptoms that can occur with transplant renal artery stenosis (TRAS) such as refractory hypertension, water retention, and graft renal dysfunction. Immediate clinical suspicion is difficult due to the nature of the progressive disease unlike TRAS. Herein, we present an interesting case of bilateral common iliac artery occlusion (AIOD, TASC II, type C) that manifested as uncontrolled blood pressure and decreased allograft function in a patient who had kidney transplant 17 years ago. The patient was successfully diagnosed with duplex scan, ankle-brachial index (ABI) and computed tomography angiography and treated with percutaneous luminal angioplasty and stent graft insertion.
