Published: June 2011

Abstract

Background
The aim of the study was to evaluate recurrent biliary events as a consequence of delay in cholecystectomy following mild biliary pancreatitis.

Methods
Between 2004 and 2007, patients with acute pancreatitis were registered prospectively in 15 Dutch hospitals. Patients with mild biliary pancreatitis were candidates for cholecystectomy. Recurrent biliary events requiring admission before and after cholecystectomy, and after endoscopic sphincterotomy (ES), were evaluated.

Results
Of 308 patients with mild biliary pancreatitis, 267 were candidates for cholecystectomy. Eighteen patients underwent cholecystectomy during the initial admission, leaving 249 potential candidates for cholecystectomy after discharge. Cholecystectomy was performed after a median of 6 weeks in 188 patients (75·5 per cent). Before cholecystectomy, 34 patients (13·7 per cent) were readmitted for biliary events, including 24 with recurrent biliary pancreatitis. ES was performed in 108 patients during the initial admission. Eight (7·4 per cent) of these patients suffered from biliary events after ES and before cholecystectomy, compared with 26 (18·4 per cent) of 141 patients who did not have ES (risk ratio 0·51, 95 per cent confidence interval 0·27 to 0·94; P = 0·015). Following cholecystectomy, eight (3·9 per cent) of 206 patients developed biliary events after a median of 31 weeks. Only 142 (53·2 per cent) of 267 patients were treated in accordance with the Dutch guideline, which recommends cholecystectomy or ES during the index admission or within 3 weeks thereafter.

Conclusion
A delay in cholecystectomy after mild biliary pancreatitis carries a substantial risk of recurrent biliary events. ES reduces the risk of recurrent pancreatitis but not of other biliary events.
Incidence, nature and impact of error in surgery
Authors: Bosma E , Veen E J , Roukema J A 
Published: June 2011

Abstract

Background
Adverse events occur in 3·8–17 per cent of hospital admissions. The purpose of this study was to analyse the incidence of medical errors and assess the feasibility of an error registry for quality improvement programmes.

Methods
Errors were recorded prospectively in a complication registry between 1 June 2005 and 31 December 2007. Events were coded according to the Trauma Registry of the American College of Surgeons; the nature of events was recorded and the severity graded using the 1992 Clavien system. Recorded events were discussed by the medical staff on a daily basis and, if by consensus judged to be errors, were saved to the registry database.

Results
Of 12 121 patients admitted to the surgical ward during the study interval, 2033 (16·8 per cent) had a complication and 735 (6·1 per cent) had an error documented in the registry. Of 873 recorded errors, 607 (69·5 per cent) were of little or no consequence (Clavien grade I) and 220 (25·2 per cent) required therapeutic intervention (Clavien grade IIa and IIb). Errors leading to permanent injury (Clavien grade III) occurred in 41 instances (4·7 per cent) and five patients (0·6 per cent) died (Clavien grade IV).

Conclusion
This study shows that errors are common in surgery, and that near misses are more frequent than errors with serious consequences. It is hypothesized that registration of near misses might prevent errors with serious consequences and thus improve quality of care.

Published: June 2011

Abstract

Background
Variations in surgical technique of temporal artery biopsy (TAB) performed for diagnosis of giant cell arteritis (GCA) may contribute to high false-negative rates. This was a retrospective analysis of a large database that explored potential associations between specimen length and diagnostic sensitivity of TAB.

Methods
Histopathological reports and medical records of patients who underwent TAB in six hospitals between 2004 and 2009 were reviewed.

Results
A total of 966 biopsies were analysed. The median postfixation specimen length was 1 (range 0·1–8·5) cm and 207 biopsies (21·4 per cent) were positive for GCA. Significant variation in prebiopsy erythrocyte sedimentation rate (ESR), arterial specimen length and positive results was noted amongst hospitals. Multivariable analysis revealed that patient age, ESR value and specimen length were independent predictors of GCA. Positive biopsies had significantly longer median specimen length compared with negative biopsies: 1·2 (range 0·3–8·5) versus 1·0 (0·2–8·0) cm respectively (P = 0·001). Receiver operating characteristic (ROC) analysis identified postfixation specimen length of at least 0·7 cm as the cut-off length with highest positive predictive value for a positive biopsy (area under ROC curve 0·574). Biopsies with specimen length of 0·7 cm or more had a significantly higher rate of positive results than smaller specimens (24·8 versus 12·9 per cent respectively; odds ratio 2·17, P = 0·001).

Conclusion
Specimen length and ESR were independent prognostic factors of a positive TAB result. A uniform referral practice and standard specimen length of approximately 1 cm could help eliminate discrepancies in the results of TAB.

Published: June 2011

Abstract

Background
Chronic pain may be a long-term problem related to mesh fixation and operative trauma after Lichtenstein hernioplasty. The aim of this study was to compare the feasibility and safety of tissue cyanoacrylate glue versus absorbable sutures for mesh fixation in Lichtenstein hernioplasty.

Methods
Lichtenstein hernioplasty was performed under local anaesthesia as a day-case operation in one of three hospitals. The patients were randomized to receive either absorbable polyglycolic acid 3/0 sutures (Dexon®; 151 hernias) or 1 ml butyl-2-cyanoacrylate tissue glue (Glubran®; 151 hernias) for fixation of lightweight mesh (Optilene®). Wound complications, pain, discomfort and recurrence were identified at 1 and 7 days, 1 month and 1 year after surgery.

Results
A total of 302 patients were included in the study. The mean(s.d.) duration of operation was 34(12) min in the glue group and 36(13) min in the suture group (P = 0·113). The need for analgesics was similar during the first 24 h after surgery. Five wound infections (3·4 per cent) were detected in the glue group and two (1·4 per cent) in the suture group (P = 0·448). The recurrence rate at 1 year was 1·4 per cent in each group (P = 1·000). The rates of foreign body sensation, acute and chronic pain were similar in the two groups. Logistic regression analysis showed that the type of mesh fixation did not predict chronic pain 1 year after surgery.

Conclusion
Mesh fixation without sutures in Lichtenstein hernioplasty was feasible without compromising postoperative outcome. Registration number: NCT00659542 (http://www.clinicaltrials.gov).
Secondary Transfer Effect of Intergroup Contact: The Role of Intergroup Attitudes, Intergroup Anxiety and Perspective Taking
Authors: Vezzali Loris , Giovannini Dino 
Published: July 2011

ABSTRACTWe conducted a field study to investigate the secondary transfer effect of intergroup contact, consisting in the generalisation of the positive effects of intergroup contact to outgroups uninvolved in the contact situation. Italian secondary school students (N = 175) filled out a questionnaire; the effects of prior contact were statistically controlled. Results showed that contact with immigrants improved attitudes toward them. In turn, these attitudes generalised to attitudes toward two dissimilar outgroups not directly involved in contact: disabled and homosexuals. Notably, we found evidence for a secondary transfer effect of intergroup anxiety and perspective taking, which generalised from immigrants to the disabled and homosexuals. Evidence was found for the mediating role of intergroup attitudes, intergroup anxiety and perspective taking. The theoretical and practical implications of findings are discussed.

ABSTRACTBackgroundThe prevalence of mental disorders among prisoners has been researched in a few countries worldwide but never previously in Spain.AimOur aim was to estimate the lifetime and last month prevalence of mental disorders in a Spanish prison population.MethodsThis is a descriptive, cross‐sectional, epidemiological study of 707 male prisoners. Sociodemographic, clinical and offending data were collected by interviewers. Offending data were confirmed using penitentiary records. Mental disorders were assessed with the clinical version of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders—Fourth Edition Axis I Disorders, and personality disorders were assessed through the Spanish version of the International Personality Disorders Examination.ResultsThe lifetime prevalence of mental disorder was 84.4%. Substance use disorder (abuse and dependence) was the most frequent disorder (76.2%) followed by anxiety disorder (45.3%), mood disorder (41%) and psychotic disorder (10.7%). The period (last month) prevalence of any mental disorder was 41.2%. Anxiety disorder was the most prevalent (23.3%) followed by substance use disorder (abuse and dependence; 17.5%), mood disorder (14.9%) and psychotic disorder (4.2%).ConclusionAlthough period prevalence figures, which are those generally provided in research into rates of mental disorder among prisoners, are useful for planning improvements to services within prisons, the fact that almost all of these men had a lifetime prevalence of at least one mental disorder suggests a much wider need for improving services, including community services, for this group.

Lewis Base Assisted Brønsted Base Catalysis: Direct Regioselective Asymmetric Vinylogous Alkylation of Allylic Sulfones
Authors: Jiang Lin , Lei Qian , Huang Xin , Cui Hai‐Lei , Zhou Xue , Chen Ying‐Chun 
Published: June 2011

AbstractA Lewis base assisted Brønsted base catalysis (LBABB) strategy is applied for direct asymmetric vinylogous alkylation of allylic sulfones with Morita–Baylis–Hillman (MBH) carbonates, in which a strong Brønsted base, tert‐butoxy anion, generated in situ from a tertiary amine catalyst and MBH carbonate, is crucial in activating unstabilized nucleophiles. The γ‐regioselective alkylation products were obtained with good to excellent enantiomeric excess values when catalyzed by a modified cinchona alkaloid.
