Aging and Comorbidities in Acute Pancreatitis I: A Meta-Analysis and Systematic Review Based on 194,702 Patients

Background: Acute pancreatitis (AP) is one of the most common cause of hospitalization among gastrointestinal diseases worldwide. Although most of the cases are mild, approximately 10-20% of patients develop a severe course of disease with higher mortality rate. Scoring systems consider age as a risk factor of mortality and severity (BISAP; >60 years, JPN>70 years, RANSON; >55 years, APACHE II >45 years). If there is a correlation between aging and the clinical features of AP, how does age influence mortality and severity? Aim: This study aimed to systematically review the effects of aging on AP. Methods: A comprehensive systematic literature search was conducted in the Embase, Cochrane, and Pubmed databases. A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis statement (PRISMA). A total of 1,100 articles were found. After removing duplicates and articles containing insufficient or irrelevant data, 33 publications involving 194,702 AP patients were analyzed. Seven age categories were determined and several mathematical models, including conventional mathematical methods (linear regression), meta-analyses (random effect model and heterogeneity tests), meta-regression, funnel plot and Egger's test for publication bias were performed. Quality assessment was conducted using the modified Newcastle-Ottawa scale. The meta-analysis was registered in the PROSPERO database (CRD42017079253). Results: Aging greatly influences the outcome of AP. There was a low severe AP incidence in patients under 30 (1.6%); however, the incidence of severe AP showed a continuous, linear increase between 20 and 70 (0.193%/year) of up to 9.6%. The mortality rate was 0.9% in patients under 20 and demonstrated a continuous linear elevation until 59, however from this age the mortality rate started elevating with 9 times higher rate until the age of 70. The mortality rate between 20 and 59 grew 0.086%/year and 0.765%/year between 59 and 70. Overall, patients above 70 had a 19 times higher mortality rate than patients under 20. The mortality rate rising with age was confirmed by meta-regression (coefficient: 0.037 CI: 0.006-0.068, p = 0.022; adjusted r2: 13.8%), and severity also (coefficient: 0.035 CI: 0.019-0.052, p < 0.001; adjusted r2: 31.6%). Conclusion: Our analysis shows a likelihood of severe pancreatitis, as well as, pancreatitis-associated mortality is more common with advanced age. Importantly, the rapid elevation of mortality above the age of 59 suggests the involvement of additional deteriorating factors such as co-morbidity in elderly.

Haemorheological and haemostatic alterations in coeliac disease and inflammatory bowel disease in comparison with non-coeliac, non-IBD subjects (HERMES): a case-control study protocol

INTRODUCTION

Haemorheological and haemostatic changes predispose to the development of arterial and venous thrombotic events; however, limited information is available on the status of these changes in coeliac disease (CeD) and inflammatory bowel disease (IBD). In this study, we aim to describe the haemorheological and haemostatic profiles of CeD and IBD patients in a Hungarian cohort of patients to investigate whether any alterations contribute to elevated thrombotic risk.

METHODS AND ANALYSIS

This is a case-control study involving newly diagnosed and followed CeD and IBD patients with age-matched and sex-matched non-CeD, non-IBD subjects with an allocation ratio of 1:1:1.After informed consent is obtained, a detailed medical history will be collected, including venous and arterial thrombotic risk factors and medications. Symptoms in CeD patients will be assessed with the Gastrointestinal Symptoms Rating Scale, and disease activity in IBD patients will be determined by disease-specific scores. Dietary adherence will be assessed among CeD patients with a thorough interview together with a measurement of self-reported adherence, dietary knowledge and urine analysis (detection of gluten immunogenic peptides). In addition to routine laboratory parameters, haemorheological (ie, erythrocyte deformability and aggregation, viscosity of whole blood and plasma) and haemostatic parameters (eg, protein C, protein S and antithrombin) with immunological indicators (ie, coeliac-specific serology and antiphospholipid antibodies) will be measured from venous blood for every participant.Primary and secondary outcomes will be haemorheological and haemostatic parameters, respectively. Univariate and multivariate statistics will be used to compare CeD and IBD patients to control subjects. Subgroup analysis will be performed by disease type in IBD, (Crohn's disease and ulcerose colitis), dietary adherence in CeD, and disease activity in IBD and CeD.

ETHICS AND DISSEMINATION

The study was approved by the Regional and Local Research Ethics Committee, University of Pécs (Ref. No. 6917). Findings will be disseminated at research conferences and in peer-reviewed journals.

Planned Transition of Adolescent Patients with Inflammatory Bowel Disease Results in Higher Remission Rates

PURPOSE

To evaluate the effect of our current transition process on clinical outcomes in adolescent patients with inflammatory bowel diseases (IBD).

DESIGN AND METHODS

Two groups of patients with IBD diagnosed in pediatric care were compared retrospectively: Group A patients did not attend the transition process, while Group B patients entered the planned transition service. Outcomes at 1-year after transfer to adult care were evaluated.

RESULTS

Forty-five patients with IBD diagnosed under the age of 18 years were identified of whom 35 had Crohn's disease and 10 had ulcerative colitis. Twenty-four patients were in Group A (without transition), and 21 patients in Group B (with at least one planned transition visit). Mean age at diagnosis was 15.1 ± 2.2 and 13.7 ± 3.0 years (p = 0.086), respectively. There were no significant differences in disease duration before transfer, Montreal classification at diagnosis, body mass index, anti-TNF therapy usage, and disease status at transfer between the two groups. A significantly higher number of Group B patients were in remission at 12 months after transfer when compared to patients in Group A (11 vs. 18, respectively, p = 0.037). There was a significant difference between groups regarding the number of scheduled visits within the examined period (9 vs. 16, p = 0.011, respectively).

CONCLUSIONS

Planned transition visits resulted in higher disease remission rate at 1-year follow-up after transfer from pediatric to adult health care system in adolescent patients with IBD.

PRACTICE IMPLICATION

Well-established transition programs in IBD are needed.

HLA-DQ2 homozygosis increases tTGA levels at diagnosis but does not influence the clinical phenotype of coeliac disease: A multicentre study

BACKGROUND AND PURPOSE

Magnitude of gluten-specific T-cell responses in coeliac disease (CD) might be dependent on HLA-DQ2 gene dose. We aimed to investigate the effects of HLA-DQB1*02 allele dose on clinical outcomes.

METHODS

We reviewed the charts of all coeliac patients attending to three Hungarian university clinics after 1997 and included those patients, who (a) were diagnosed with CD, (b) underwent high-resolution HLA typing and (c) were ≥18 years at the time of data collection. HLA typing was performed to determine DQB1*02 allele dose. Patients were divided into risk groups by DQB1*02 allele dose, as follows: high-, intermediate- and low-risk groups corresponded to a double, single and zero doses, respectively. We used ANOVA and Pearson's chi-squared test to explore association between HLA risk and clinical variables.

RESULTS

A total of 727 coeliac patients attended the clinics but only 105 (14.4%) patients were eligible for inclusion. High, intermediate and low HLA risk patients comprised 35.3%, 52.3% and 12.3% of the study population, respectively. Double dose of HLA-DQB1*02 was more frequent in patient with high tTGA level (>10 times the upper limit of normal; p = 0.045). Gene dose was not associated with younger age at diagnosis (p = 0.549), gender (p = 0.739), more severe diagnostic histology (p = 0.318), more frequent classical presentation (p = 0.846), anaemia (p = 0.611), metabolic bone disease (p = 0.374), dermatitis herpetiformis (p = 0.381) and autoimmune diseases (p = 0.837).

CONCLUSIONS

Our study shows a significant gene dose effect in terms of tTGA level at diagnosis, but no significant association between HLA-DQB1*02 allele dose and the clinical outcomes in CD.

Classical celiac disease is more frequent with a double dose of HLA-DQB1*02: A systematic review with meta-analysis

Background and aims

Experimental data suggest that the HLA-DQ2 gene dose has a strong quantitative effect on clinical outcomes and severity of celiac disease (CD). We aimed to conduct a meta-analysis with systematic review to investigate the association between HLA-DQB1*02 gene doses and the characteristics of CD.

Methods

We searched seven medical databases for studies discussing HLA-DQB1 gene dose in CD and various disease characteristics, such as clinical presentation, histology, age at diagnosis, and comorbidities. Odds ratios (OR, for categorical variables) and weighted mean differences (for age) were calculated to compare patients with a double dose of HLA-DQB1*02 versus those with single and zero doses. Heterogeneity was tested with I²-statistics and explored by study subgroups (children and adults).

Results

Twenty-four publications were eligible for meta-analysis. Classical CD was more frequent with a double versus single dose of the HLA-DQB1*02 allele (OR = 1.758, 95%CI: 1.148–2.692, I² = 0.0%). In pediatric studies, gene dose effect was more prominent (OR = 2.082, 95%CI: 1.189–3.646, I² = 0.0% and OR = 3.139, 95%CI: 1.142–8.630, I² = 0.0% for the comparisons of double versus single and double versus zero dose, respectively). Atrophic histology was more prevalent with a double versus zero dose (OR = 2.626, CI: 1.060–6.505, I² = 21.3%). We observed no gene dose effect regarding diarrhea, age at diagnosis, the severity of villous atrophy, and the association with type 1 diabetes mellitus.

Conclusion

A double dose of HLA-DQB1*02 gene seems to predispose patients to developing classical CD and villous atrophy. Risk stratification by HLA-DQB1*02 gene dose requires further clarification due to the limited available evidence.

[The evaluation of paroxysmal events in neonates and infants]

Background and purpose

Differential diagnosis of neonatal and infantile seizures based only on inspection poses a challenge even for specialists. Aims - To investigate the evaluations of neonatal and infantile paroxysmal events based only on inspection. Research question - Is there any difference in the opinion of neonatologists, paediatric neurologists and neurologists about the assessment of common paroxysmal events in infancy?

Methods

Video recordings about paroxysmal movements of 15 neonates or infants (aged 2 days- 5 months) were displayed for 47 paediatric neurologists, 35 neonatologists and nurses working in Neonatal or Perinatal Intensive Care Units and 43 neurologists. They had to decide without knowing the past medical history or EEG results whether events presented were epileptic or nonepileptic in nature.

Results

Answers of neonatologists and paediatric neurologists were correct in 67% of cases (824/1230), no significant difference was found between their results. The largest uncertainty was in the judgement of discrete hand movements and very rapid clonus with epileptic origin, they were judged correctly by only one third of participants. The result of neurologists was only slightly, but not significantly different from that of paediatric neurologists.

Conclusion

In most cases, the correct diagnosis of neonatal and infantile paroxysmal events requires video-EEG recording. No significant difference was revealed between the evaluation of neonatologists and paediatric neurologists about the differential diagnosis of movements. The ongoing cooperation of paediatric neurologists and neurologists going back to several decades facilitates the shaping of a common perspective.

Helicobacter pylori infection reduces the risk of Barrett's esophagus: A meta-analysis and systematic review

INTRODUCTION

The prevalence of Helicobacter pylori infection (HPI) has been decreasing in developed countries, with an increasing prevalence of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) at the same time. The aim of our meta-analysis was to quantify the risk of BE in the context of HPI.

METHODS

A systematic search was conducted in 3 databases for studies on BE with data on prevalence of HPI from inception until December 2016. Odds ratios for BE in HPI were calculated by the random effects model with subgroup analyses for geographical location, presence of dysplasia in BE, and length of the BE segment.

RESULTS

Seventy-two studies were included in the meta-analysis, including 84 717 BE cases and 390 749 controls. The overall analysis showed that HPI reduces the risk of BE; OR = 0.68 (95% CI: 0.58-0.79, P < .001). Subgroup analyses revealed risk reduction in Asia OR = 0.53 (95% CI: 0.33-0.84, P = .007), Australia OR = 0.56 (95% CI: 0.39-0.80, P = .002), Europe OR = 0.77 (95% CI: 0.60-0.98, P = .035), and North-America OR = 0.59 (95% CI: 0.47-0.74, P < .001). The risk was significantly reduced for dysplastic BE, OR = 0.37 (95% CI: 0.26-0.51, P < .001) for non-dysplastic BE, OR = 0.51 (95% CI: 0.35-0.75, P = .001), and for long segment BE, OR = 0.25 (95% CI: 0.11-0.59, P = .001) in case of HPI.

CONCLUSIONS

This extensive meta-analysis provides additional evidence that HPI is associated with reduced risk of BE. Subgroup analyses confirmed that this risk reduction is independent of geographical location. HPI is associated with significantly lower risk of dysplastic, non-dysplastic, and long segment BE.

Centralized Care For Acute Pancreatitis Significantly Improves Outcomes

Aims: In this observational study, we investigated whether specialized care improves outcomes for acute pancreatitis (AP).Methods: Consecutive patients admitted to two university hospitals with AP were enrolled in this study between 1 January 2016 and 31 December 2016 (Center A: specialized center; Center B: general hospital). Data on demographic characteristics and AP etiology, severity, mortality and quality of care (enteral nutrition and antibiotic use) were extracted from the Hungarian Acute Pancreatitis Registry. An independent sample t-test, Mann–Whitney test, chi-squared test or Fisher’s test were used for statistical analyses. Costs of care were calculated and compared in the two models of care.Results: There were 355 patients enrolled, 195 patients in the specialized center (Center A) and 160 patients in the general hospital (Center B). There was no difference in mean age (57.02 ±17.16 vs. 57.31 ±16.50 P=0.872) and sex ratio (56% males vs. 57% males, P=0.837) between centres, allowing a comparison without selection bias. Center A had lower mortality (n=2, 1.03% vs. n=16, 6.25%, p=0.007), more patients received enteral feeding (n=179, 91.8%, vs. n=36, 22.5%, p<0.001) and fewer patients were treated with antibiotics (n=85, 43.6% vs. n=123, 76.9%, p=0.001). In Center A the median length of hospitalization was shorter (Me 6, IQR 5–9 vs. Me 8, IQR 6–11, p=0.02) and the costs of care were by 25% lower.Conclusion: Our data suggests that treatment of AP in specialized centers reduces mortality, length of hospitalization and thus might reduce the costs.

Intralesional steroid is beneficial in benign refractory esophageal strictures: A meta-analysis

AIM

To analyze the effect of intralesional steroid injections in addition to endoscopic dilation of benign refractory esophageal strictures.

METHODS

A comprehensive search was performed in three databases from inception to 10 April 2017 to identify trials, comparing the efficacy of endoscopic dilation to dilation combined with intralesional steroid injections. Following the data extraction, meta-analytical calculations were performed on measures of outcome by the random-effects method of DerSimonian and Laird. Heterogeneity of the studies was tested by Cochrane's Q and I2 statistics. Risk of quality and bias was assessed by the Newcastle Ottawa Scale and JADAD assessment tools.

RESULTS

Eleven articles were identified suitable for analyses, involving 343 patients, 235 cases and 229 controls in total. Four studies used crossover design with 121 subjects enrolled. The periodic dilation index (PDI) was comparable in 4 studies, where the pooled result showed a significant improvement of PDI in the steroid group (MD: -1.12 dilation/month, 95%CI: -1.99 to -0.25 P = 0.012; I2 = 74.4%). The total number of repeat dilations (TNRD) was comparable in 5 studies and showed a non-significant decrease (MD: -1.17, 95%CI: -0.24-0.05, P = 0.057; I2 = 0), while the dysphagia score (DS) was comparable in 5 studies and did not improve (SMD: 0.35, 95%CI: -0.38, 1.08, P = 0.351; I2 = 83.98%) after intralesional steroid injection.

CONCLUSION

Intralesional steroid injection increases the time between endoscopic dilations of benign refractory esophageal strictures. However, its potential role needs further research.

Steroid but not Biological Therapy Elevates the risk of Venous Thromboembolic Events in Inflammatory Bowel Disease: A Meta-Analysis

BACKGROUND AND AIMS

Inflammatory bowel disease [IBD] is associated with a 1.5- to 3-fold increased risk of venous thromboembolism [VTE] events. The aim of this study was to determine the risk of VTE in IBD as a complication of systemic corticosteroids and anti-tumour necrosis factor alpha [TNFα] therapies.

METHODS

A systematic review and meta-analysis was conducted, which conforms to the Preferred Reporting Items for Systematic Reviews and Meta-analyses [PRISMA] statement. PubMed, EMBASE, Cochrane Library and Web of Science were searched for English-language studies published from inception inclusive of 15 April 2017. The population-intervention-comparison-outcome [PICO] format and statistically the random-effects and fixed-effect models were used to compare VTE risk during steroid and anti-TNFα treatment. Quality of the included studies was assessed using the Newcastle-Ottawa scale. The PROSPERO registration number is 42017070084.

RESULTS

We identified 817 records, of which eight observational studies, involving 58518 IBD patients, were eligible for quantitative synthesis. In total, 3260 thromboembolic events occurred. Systemic corticosteroids were associated with a significantly higher rate of VTE complication in IBD patients as compared to IBD patients without steroid medication (odds ratio [OR]: 2.202; 95% confidence interval [CI]: 1.698-2.856, p < 0.001). In contrast, treatment with anti-TNFα agents resulted in a 5-fold decreased risk of VTE compared to steroid medication [OR: 0.267; 95% CI: 0.106-0.674, p = 0.005].

CONCLUSION

VTE risk should be carefully assessed and considered when deciding between anti-TNFα and steroids in the management of severe flare-ups. Thromboprophylaxis guidelines should be followed, no matter the therapy choice.

Chronic kidney disease severely deteriorates the outcome of gastrointestinal bleeding: A meta-analysis

AIM

To understand the influence of chronic kidney disease (CKD) on mortality, need for transfusion and rebleeding in gastrointestinal (GI) bleeding patients.

METHODS

A systematic search was conducted in three databases for studies on GI bleeding patients with CKD or end-stage renal disease (ESRD) with data on outcomes of mortality, transfusion requirement, rebleeding rate and length of hospitalization (LOH). Calculations were performed with Comprehensive Meta-Analysis software using the random effects model. Heterogeneity was tested by using Cochrane's Q and I2 statistics. Mean difference (MD) and OR (odds ratio) were calculated.

RESULTS

1063 articles (EMBASE: 589; PubMed: 459; Cochrane: 15) were found in total. 5 retrospective articles and 1 prospective study were available for analysis. These 6 articles contained data on 406035 patients, of whom 51315 had impaired renal function. The analysis showed a higher mortality in the CKD group (OR = 1.786, 95%CI: 1.689-1.888, P < 0.001) and the ESRD group (OR = 2.530, 95%CI: 1.386-4.616, P = 0.002), and a rebleeding rate (OR = 2.510, 95%CI: 1.521-4.144, P < 0.001) in patients with impaired renal function. CKD patients required more unit red blood cell transfusion (MD = 1.863, 95%CI: 0.812-2.915, P < 0.001) and spent more time in hospital (MD = 13.245, 95%CI: 6.886-19.623, P < 0.001) than the controls.

CONCLUSION

ESRD increases mortality, need for transfusion, rebleeding rate and LOH among GI bleeding patients. Prospective patient registries and observational clinical trials are crucially needed.

Deficiency of innate-like T lymphocytes in chronic obstructive pulmonary disease

Background

Based on the phenotypic and functional characteristics unconventional T-lymphocytes such as invariant natural killer T (iNKT) cells and mucosal-associated invariant T (MAIT) cells link the innate and adaptive immune responses. Up to now data are scarce about their involvement in pulmonary disorders including chronic obstructive pulmonary disease (COPD). This study explores simultaneously the frequencies of iNKT and MAIT cells in the peripheral blood and sputum of stable and exacerbating COPD patients.

Methods

By means of multicolor flow cytometry frequencies of total iNKT and MAIT cells and their subsets were enumerated in peripheral blood and sputum samples of healthy controls, and COPD patients. In addition, gene expression of TCR for iNKT, MAIT cells, and CD1d, MR1 were assessed by qPCR in the study cohorts.

Results

Percentages of total iNKT and MAIT cells were dramatically dropped in blood, and reduced numbers of iNKT cells were observed in the sputum of COPD patients. Furthermore decreased DN and increased CD4+ iNKT subsets, while increased DN and decreased CD8+ MAIT subpopulations were measured in the blood of COPD patients. Reduced invariant TCR mRNA levels in COPD patients had confirmed these previous findings. The mRNA expression of CD1d and MR1 were increased in stable and exacerbating COPD patients; however both molecules were decreased upon antibiotic and systemic steroid treatments.

Conclusions

Our results support the notion that both invariant T-cell populations are affected in COPD. Further detailed analysis of invariant T cells could shed more light into the complex interactions of these lymphocyte groups in COPD pathogenesis.

Association between AIRE gene polymorphism and rheumatoid arthritis: a systematic review and meta-analysis of case-control studies

Autoimmune regulator (AIRE) is a transcription factor that functions as a novel player in immunological investigations. In the thymus, it has a pivotal role in the negative selection of naive T-cells during central tolerance. Experimental studies have shown that single nucleotide polymorphism (SNP) alters transcription of the AIRE gene. SNPs thereby provide a less efficient negative selection, propagate higher survival of autoimmune T-cells, and elevate susceptibility to autoimmune diseases. To date, only rheumatoid arthritis (RA) has been analysed by epidemiological investigations in relation to SNPs in AIRE. In our meta-analysis, we sought to encompass case-control studies and confirm that the association between SNP occurrence and RA. After robust searches of Embase, PubMed, Cochrane Library, and Web of Science databases, we found 19 articles that included five independent studies. Out of 11 polymorphisms, two (rs2075876, rs760426) were common in the five case-control studies. Thus, we performed a meta-analysis for rs2075876 (7145 cases and 8579 controls) and rs760426 (6696 cases and 8164 controls). Our results prove that rs2075876 and rs760426 are significantly associated with an increased risk of RA in allelic, dominant, recessive, codominant heterozygous, and codominant homozygous genetic models. These findings are primarily based on data from Asian populations.

Down-regulation of Toll-like Receptor TLR4 Is Associated with HPV DNA Integration in Penile Carcinoma

BACKGROUND/AIM

Development of penile cancers is attributed to HPV-related carcinogenesis. Our aim was to analyze HPV positivity and TLR4, p16^ink4a and p53 expression.

MATERIALS AND METHODS

HPV presence was assessed with virus-specific TaqMan PCR and HPV Genotyping Test in 31 penile cancers. Immunohistochemistry was carried out on tissue microarray.

RESULTS

TLR4 expression was detected in 4 of the 16 HPV positive and 13 of the 15 HPV negative tumors. We found a significant inverse correlation between HPV positivity and TLR4 expression (p=0.0006). Ten of the 16 HPV-positive but none of the 15 HPV-negative tumors expressed p16INK4a. A significant correlation was seen between p53 expression and lack of HPV DNA (p=0.0191) as well as between TLR4 and p53 expression (p=0.0198) in penile cancers.

CONCLUSION

Our findings suggest a protective role of TLR4 expression against HPV DNA integration and the viral and non-viral carcinogenesis of penile cancer.

Epileptic seizure or not? Proportion of correct judgement based only on a video recording of a paroxysmal event

PURPOSE

Our study was intended to measure the proportion of correct seizure recognition among different medical and non-medical groups based on only a video recording.

METHODS

Video recordings about paroxysmal movements of 15 very young infants (2days - 5 months of age) were displayed for six groups: 159 1st-year medical students, 65 4-5th-year medical students, 52 paediatric residents, 18 paediatric neurologists from different European countries, 43 adult neurologists and 37 parents whose children were treated at our Department. All participants were asked to decide which recording they considered as of epileptic origin or a non-epileptic event. Correct answer rate (CAR) was calculated in each group for every video.

RESULTS

The average CAR was the lowest in the group of 1st-year medical students (36.6%), the best results were reached by paediatric neurologists (67.4%). The CAR was significantly different between the groups of 1st-year medical students and paediatric neurologists (p=0.02), and between the groups of 1st-year medical students and residents (p=0.045). The CAR of the most deceptive epileptic seizure was only 18.2%. The judgement of parents proved to be better than that of the 1st-year medical students.

CONCLUSIONS

Recognising epileptic seizures in very young infants without EEG is extremely inaccurate. Even trained paediatric neurologists were able to judge correctly the different movement types in only 67.4% of the cases. The role of education and experience is clearly indicated by the increase in CAR from 1st-year medical students through well-trained paediatric neurologists.

Efficacy of intensive hand physical therapy in patients with systemic sclerosis

OBJECTIVES

To evaluate the efficacy of a three-week period of complex and intensive hand physical therapy on hand function in patients with systemic sclerosis (SSc).

METHODS

Thirty-one patients with SSc were treated. Hand stretching exercises, ergotherapy supplemented with thermal and mud baths, whirlpool therapy and soft tissue massage were daily used during a three-week period. The control SSc group (n=22) received similar management for their large joints leaving out their hands. The primary outcomes of this study were the Health Assessment Questionnaire (HAQ) and the Disabilities of the Arm, Shoulder and Hand (DASH). Hand Anatomic Index (HAI), Cochin Hand Function (CHFT) and clinical characteristics were also assessed before starting the therapy and six months afterwards.

RESULTS

Six months after the investigation period, only the group receiving hand physical therapy showed improvement in HAQ and DASH scores compared to the baseline values (p<0.05). The improvement in median HAQ value (25%-75% quartiles) reached the clinical meaningful rate (baseline 1.125/0.625-1.625/ versus 0.75/0.25-1.5/ at six months). Visual analogue scales of global pain (p<0.01) and Raynaud's phenomenon (p<0.05) also had better results than at baseline. HAI, gripping strength and CHFT also showed some improvement, but did not reach the significance level of change by the end of the six-month observation period.

CONCLUSIONS

The complex physical therapy caused favourable changes in both the HAQ and the DASH indicating that this particular program had some long-term beneficial effect on hand function in patients with SSc.

Transpancreatic sphincterotomy has a higher cannulation success rate than needle-knife precut papillotomy - a meta-analysis

Background and aim While many studies have discussed the different cannulation techniques used in patients with difficult biliary access, no previous meta-analyses have compared transpancreatic sphincterotomy (TPS) to other advanced techniques. Therefore, we aimed to identify all studies comparing the efficacy and adverse event rates of TPS with needle-knife precut papillotomy (NKPP), the most commonly used technique, and to perform a meta-analysis. Methods The Embase, PubMed, and Cochrane databases were searched for trials comparing the outcomes of TPS with NKPP up till December 2016. A meta-analysis focusing on outcome (cannulation success, post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), post-procedural bleeding, and total adverse events) was performed. The population, intervention, comparison, outcome (PICO) format was used to compare these cannulation approaches. Five prospective and eight retrospective studies were included in our meta-analysis. Results NKPP has a significantly lower success rate (odds ratio [OR] 0.50, P = 0.046; relative risk [RR] 0.92, P = 0.03) and a higher rate of bleeding complications (OR 2.24, P = 0.02; RR 2.18, P = 0.02) than TPS. However, no significant differences were found in PEP (OR 0.79, P = 0.24; RR 0.80, P = 0.19), perforation (risk difference [RD] 0.01, P = 0.23), or total complication rates (OR 1.22, P = 0.44; RR 1.17, P = 0.47). Conclusion While TPS has a higher success rate in difficult biliary access and causes less bleeding than NKPP, there are no differences in PEP, perforation, or total complication rates between the two approaches. We conclude that TPS, in the hands of expert endoscopists, is a safe procedure, which should be used more widely in patients with difficult biliary access.
