Prognostic scoring system for peripheral nerve repair in the upper extremity

So far, predictive models with individualized estimates of prognosis for patients with peripheral nerve injuries are lacking. Our group has previously shown the prognostic value of a standardized scoring system by examining the functional outcome after acute, sharp complete laceration and repair of median and/or ulnar nerves at various levels in the forearm. In the present study, we further explore the potential mathematical model in order to devise an effective prognostic scoring system. We retrospectively collected medical record data of 73 cases with a peripheral nerve injury in the upper extremity in order to estimate which patients would return to work, and what time was necessary to return to the pre‐injury work. Postoperative assessment followed the protocol described by Rosén and Lundborg. We found that return to pre‐injury work can be predicted with high sensitivity (100%) and specificity (95%) using the total numerical score of the Rosén and Lundborg protocol at the third follow‐up interval (TS3) as well as the difference between the TS3 and the total score at second follow‐up interval (TS2). In addition, the factors age and type of injured nerve (median, ulnar, or combined) can determine the time of return to work based on a mathematical model. This prognostic protocol can be a useful tool to provide information about the functional and social prospects of the patients with these types of injuries. © 2012 Wiley Periodicals, Inc.

Giant extra gastrointestinal stromal tumor of lesser omentum obscuring the diagnosis of a choloperitoneum

INTRODUCTIONHerein we present an extremely rare case of a giant extra gastrointestinal stromal tumor (EGIST) of the lesser omentum obscuring the diagnosis of a choloperitoneum.PRESENTATION OF CASEA 79 years old female was admitted to our hospital with symptoms of vomiting and epigastric pain. Abdominal computer tomography revealed a sizable formation that was diagnosed as a tumor of the pancreas. In laparotomy, a choloperitoneum was diagnosed as the cause of patient's symptoms. A tumor adherent firmly to the lesser curvature of stomach was also discovered. Cholecystectomy and subtotal gastrectomy were performed. Histologically, the tumor was diagnosed as a EGIST of the lesser omentum. The patient did not receive any adjuvant therapy and after two years of follow up she is without any recurrence.DISCUSSIONOmental EGISTs may remain clinically silent despite the large tumor's size. It is difficult to differentiate a EGIST in the lesser omentum from a GIST of the lesser curvature of the stomach, despite the use of advanced radiological imaging techniques. Our case of a giant EGIST of lesser omentum obscuring the diagnosis of acute choloperitoneum is the only one reported in literature.CONCLUSIONEGISTs that arise from the omentum are very rare and complete surgical resection is the only effective treatment approach. Adjuvant therapy following resection of localized disease has become standard of care in high risk cases.     

Anti-stigma training and positive changes in mental illness stigma outcomes in medical students in ten countries: a mediation analysis on pathways via empathy development and anxiety reduction

Purpose

Studies of mental illness stigma reduction interventions have been criticised for failing to evaluate behavioural outcomes and mechanisms of action. This project evaluates training for medical students entitled ‘Responding to Experienced and Anticipated Discrimination’ (READ), developed to focus on skills in addition to attitudes and knowledge. We aimed to (i) evaluate the effectiveness of READ with respect to knowledge, attitudes, and clinical communication skills in responding to mental illness-related discrimination, and (ii) investigate whether its potential effectiveness was mediated via empathy or/and intergroup anxiety.

Methods

This is an international multisite non-randomised pre- vs post-controlled study. Eligible medical students were currently undertaking their rotational training in psychiatry. Thirteen sites across ten countries (n = 570) were included in the final analysis.

Results

READ was associated with positive changes in knowledge (mean difference 1.35; 95% CI 0.87 to 1.82), attitudes (mean difference − 2.50; 95% CI − 3.54 to − 1.46), skills (odds ratio 2.98; 95% CI 1.90 to 4.67), and simulated patient perceived empathy (mean difference 3.05; 95% CI 1.90 to 4.21). The associations of READ with knowledge, attitudes, and communication skills but not with simulated patient perceived empathy were partly mediated through student reported empathy and intergroup anxiety.

Conclusion

This is the first study to identify mediating effects of reduced intergroup anxiety and increased empathy in an evaluation of anti-stigma training that includes behavioural measures in the form of communication skills and perceived empathy. It shows the importance of both mediators for all of knowledge, skills, and attitudes, and hence of targeting both in future interventions.
