1Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered.Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López 2014World Journal of Radiology2014,6,6:30
2Pathogenesis of occult chronic hepatitis B virus infection显示文摘Occult hepatitis B infection(OBI) is characterized by hepatitis B virus(HBV) DNA in serum in the absence of hepatitis B surface antigen(HBsAg) presenting HBsAg-negative and anti-HBc positive serological patterns.Occult HBV status is associated in some cases with mutant viruses undetectable by HBsAg assays;but more frequently it is due to a strong suppression of viral replication and gene expression.OBI is an entity with world-wide diffusion.The failure to detect HBsAg,despite the persistence of the viral DNA,is due in most cases to the strong suppression of viral replication and gene expression that characterizes this'occult'HBV infection;although the mechanisms responsible for suppression of HBV are not well understood.The majority of OBI cases are secondary to overt HBV infection and represent a residual low viremia level suppressed by a strong immune response together with histological derangements which occurred during acute or chronic HBV infection.Much evidence suggests that it can favour the progression of liver fibrosis and the development of hepatocellular carcinoma.Rocio Aller de la Fuente María L Gutiérrez Javier Garcia-Samaniego Conrado Fernández-Rodriguez Jose Luis Lledó Gregorio Castellano 2011World Journal of Gastroenterology2011,17,12:12
3Review of the treatment of liver hydatid cysts显示文摘A review was carried out in Medline,LILACS and the Cochrane Library.Our database search strategy included the following terms: 'hydatid cyst','liver','management','meta-analysis' and 'randomized controlled trial'.No language limits were used in the literature search.The latest electronic search date was the 7th of January 2014.Inclusion and exclusion criteria: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for analysis.Information from editorials,letters to publishers,low quality review articles and studies done on animals were excluded from analysis.Additionally,well-structured abstracts from relevant articles were selected and accepted for analysis.Standardized forms were designed for data extraction; two investigators entered the data on patient demographics,methodology,recurrence of HC,mean cyst size and number of cysts per group.Four hundred and fourteen articles were identified using the previously described search strategy.After applying the inclusion and exclusion criteria detailed above,57 articles were selected for final analysis: one meta-analysis,9 randomized clinical trials,5 non-randomized comparative prospective studies,7 non-comparative prospective studies,and 34 retrospective studies(12 comparative and 22 noncomparative).Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid cysts.More studies in the literature support the effectiveness of radical treatment compared with conservative treatment.Conservative surgery with omentoplasty is effective in preventing postoperative complications.A laparoscopic approach is safe in some situations.Percutaneous drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the liver.Radical surgery with preand post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates.Concepción Gomez i Gavara Rafael López-Andújar Tatiana Belda Ibáez José M Ramia ngel ngel Moya Herraiz Francisco Orbis Castellanos Eugenia Pareja Ibars Fernando San Juan Rodríguez 2015World Journal of Gastroenterology2015,21,1:8
4同步构绘学龄儿童脑模版和生长曲线显示文摘大脑的生长发育曲线和各年龄的标准脑模版是研究个体发育异常的必要工具.本研究构建了以一岁为间隔的儿科脑模版及相应的脑发育轨线,探究了年龄和民族在儿科脑影像研究中的影响.本研究使用了来自中美共四个站点且实验设计相同的两组纵向加速儿童脑影像队列数据,对正常发育的学龄儿童间隔五个季节进行了三次磁共振扫描.我们分别构建并比较了不同民族和年龄阶段的脑模版及发育轨线.对457名和133名正常发育的中美儿童青少年进行了总计674次和190次磁共振扫描.我们评估了使用不同民族和年龄阶段的脑模版进行配准产生的形变量,并建模大脑皮层400个不同区域体积的生长曲线.分析结果表明:构建各年龄阶段和民族特异性的脑模版对于脑生长发育曲线的绘制是必要的.脑体积在不同民族间的发育差异主要体现在结构和功能上个体差异较为明显的外侧额叶和顶叶区域,使用年龄和民族相对应的脑模版可以避免在构绘脑生长曲线时由此产生的系统偏差.本研究的所有结果及分析代码均已公开.董昊铭 F.Xavier Castellanos 杨宁 张喆 周荃 何叶 张蕾 徐婷 Avram J.Holmes B.T.Thomas Yeo 陈飞燕 王滨 Christian Beckmann Tonya White Olaf Sporns 邱江 冯廷勇 陈安涛 刘勋 陈旭 翁旭初 Michael P.Milham 左西年 2020Science Bulletin2020,65,22:4

7Second-look surgery plus hyperthermic intraperitoneal chemotherapy for patients with colorectal cancer at high risk of peritoneal carcinomatosis:Does it really save lives?显示文摘The treatment of peritoneal carcinomatosis (PC) of colorectal origin with cytoreductive surgery(CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has a 5-year recurrence-free or cure rate of at least 16%, so it is no longer labeled as a fatal disease, and offers prolonged survival for patients with a low peritoneal carcinomatosis index. Metachronous PC of colorectal origin is so predictable that there is a model which has been used to successfully determine the individual risk of each patient. Patients at risk are clearly identified; those with the highest risk have small peritoneal nodules present in the first surgery (70% probability of developing PC), ovarian metastases(60%), perforated tumor onset or intraoperative tumor rupture(50%). Current clinical, biological and imaging techniques still lack sufficient sensitivity to diagnose PC in its initial stages, when CRS plus HIPEC has a greater impact and a higher cure rate. Second-look surgery with HIPEC or prophylactic HIPEC at the time of the first intervention have been proposed as means of preventing and/or anticipating clinical or radiological relapse in at-risk patients. Both techniques have shown a significant decrease in peritoneal relapses and should be considered essential weapons in the management of colorectal cancer.Delia Cortes-Guiral Dominique Elias Pedro Antonio Cascales-Campos Alfredo Badía Yébenes Ismael Guijo Castellano Ana Isabel León Carbonero JoséIgnacio Martín Valadés Jesus Garcia-Foncillas Damian Garcia-Olmo 2017World Journal of Gastroenterology2017,23,3:3

11Factors associated with early virological response to peginterferon-α-2a/ribavirin in chronic hepatitis C显示文摘AIM: To evaluate the impact of sociodemographic/clinical factors on early virological response (EVR) to pegin-terferon/ribavirin for chronic hepatitis C (CHC) in clinical practice. METHODS: We conducted a multicenter, cross-sectional, observational study in Hepatology Units of 91 Spanish hospitals. CHC patients treated with peginterferon α-2a plus ribavirin were included. EVR was defined as undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or ≥ 2 log HCV-RNA decrease after 12 wk of treatment. A bivariate analysis of sociodemographic and clinical variables associated with EVR was carried out. Independent factors associated with an EVR were analyzed using a multiple regression analysis that included the following baseline demographic and clinical variables: age (≤ 40 years vs > 40 years), gender, race, educational level, marital status and family status, weight, alcohol and tobacco consumption, source of HCV infection, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and gamma glutamyl transpeptidase (GGT) (≤ 85 IU/mL vs > 85 IU/mL), serum ferritin, serum HCV-RNA concentration (< 400 000 vs ≥ 400 000), genotype (1/4 vs 3/4), cirrhotic status and ribavirin dose (800/1000/1200 mg/d).RESULTS: A total of 1014 patients were included in the study. Mean age of the patients was 44.3 ± 9.8 years, 70% were male, and 97% were Caucasian. The main sources of HCV infection were intravenous drug abuse (25%) and blood transfusion (23%). Seventyeight percent were infected with HCV genotype 1/4 (68% had genotype 1) and 22% with genotypes 2/3. The HCV-RNA level was > 400 000 IU/mL in 74% of patients. The mean ALT and AST levels were 88.4 ± 69.7 IU/mL and 73.9 ± 64.4 IU/mL, respectively, and mean GGT level was 82 ± 91.6 IU/mL. The mean ferritin level was 266 ± 284.8 μg/L. Only 6.2% of patients presented with cirrhosis. All patients received 180 mg of peginterferon α-2a. The most frequently used ribavirin doses were 1000 mg/d (41%) and 1200 mg/d (41%). The planned treatment duration was 48 wk for 92% of patients with genotype 2/3 and 24 wk for 97% of those with genotype 1/4 (P < 0.001). Seven percent of patients experienced at least one reduction in ribavirin or peginterferon α-2a dose, respectively. Only 2% of patients required a dose reduction of both drugs. Treatment was continued until week 12 in 99% of patients. Treatment compliance was ≥ 80% in 98% of patients. EVR was achieved in 87% of cases (96% vs 83% of patients with genotype 2/3 and 1/4, respectively; P < 0.001). The bivariate analysis showed that patients who failed to achieve EVR were older (P < 0.005), had higher ALT (P < 0.05), AST (P < 0.05), GGT (P < 0.001) and ferritin levels (P < 0.001), a diagnosis of cirrhosis (P < 0.001), and a higher baseline viral load (P < 0.05) than patients reaching an EVR. Age < 40 years [odds ratios (OR): 0.543, 95%CI: 0.373-0.790, P < 0.01], GGT < 85 IU/mL (OR: 3.301, 95%CI: 0.192-0.471, P < 0.001), low ferritin levels (OR: 0.999, 95%CI: 0.998-0.999, P < 0.01) and genotype other than 1/4 (OR: 4.716, 95%CI: 2.010-11.063, P < 0.001) were identified as independent predictors for EVR in the multivariate analysis. CONCLUSION: CHC patients treated with peginterferon-α-2a/ribavirin in clinical practice show high EVR. Older age, genotype 1/4, and high GGT were associated with lack of EVR.Javier García-Samaniego Miriam Romero Rafael Granados Remedios Alemán Miguel Jorge Juan Dolores Suárez Ramón Pérez Gregorio Castellano Carlos González-Portela 2013World Journal of Gastroenterology2013,19,12:2

18Synthetic cannabinoids 2015: An update for pediatricians in clinical practice显示文摘Synthetic cannabinoids are a group of substances in the world of designer drugs that have become increasingly popular over the past few years. Synthetic cannabinoids are a chemically diverse group of compounds functionally similar to THC. Since first appearing on the world market a few years ago these compounds have evolved rapidly. Newer more potent analogues have been developed. Identifying youth who abuse these substances can be difficult. Newer forms of consumption have also evolved. These products are now manufactured in products that look like natural cannabis resin and in liquid cartridges used in electronic cigarettes. Synthetic cannabinoids appear to be associated with potentially dangerous health effects that are more severe than that of marijuana. Some synthetic cannabinoid compounds have been associated with serious physical consequences, such as, seizures, myocardial infarction and renal damage. In addition, psychoactive effects, such as aggression, confusion, anxiety and psychosis have also been reported. The diagnosis remains primarily clinical with toxicological confirmation difficult due to manufacturers constantly developing new analogues to avoid detection. Pediatricians are urged to familiarize themselves with these drugs and the typical presentations of patients who use them.Daniel Castellanos Leonard M Gralnik 2016World Journal of Clinical Pediatrics2016,5,1:2
