Systematic review of endoscopic ultrasonography versus endoscopic retrograde cholangiopancreatography for suspected choledocholithiasis
Authors: Petrov M S , Savides T J 
Published: July 2009

Abstract

Background
Endoscopic ultrasonography (EUS) has emerged as an accurate diagnostic alternative to endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to perform a systematic review of all randomized controlled trials of EUS-guided ERCP versus ERCP alone in patients with suspected choledocholithiasis.

Methods
The search for eligible studies was carried out using the MEDLINE, Cochrane Central Register of Controlled Trials, and Science Citation Index electronic databases. Meta-analysis was conducted using a random-effects model.

Results
Four trials containing 213 patients randomized to EUS-guided ERCP and 210 to ERCP alone were selected. In the EUS-guided ERCP group, ERCP was avoided in 143 patients (67·1 per cent) when EUS did not detect choledocholithiasis. The use of EUS significantly reduced the risk of overall complications (relative risk 0·35 (95 per cent confidence interval (c.i.) 0·20 to 0·62); P &lt; 0·001) and post-ERCP acute pancreatitis (relative risk 0·21 (95 per cent c.i. 0·06 to 0·83); P = 0·030).

Conclusion
By performing EUS first, ERCP may be safely avoided in two-thirds of patients with common bile duct stones. Application of EUS in the selection of patients for therapeutic ERCP significantly reduces the complication rate.
Childhood risk factors for offending before first psychiatric admission for people with schizophrenia: a case–control study of high security hospital admissions
Authors: Jones Roland M. , Van den Bree Marianne , Ferriter Michael , Taylor Pamela J. 
Published: July 2009

AbstractBackground People with schizophrenia who offend do not constitute a homogenous population. Pre‐illness characteristics may distinguish groups.Aims To test for differences in prevalence of childhood risk factors for offending between serious offenders with schizophrenia who had started offending before their first ever psychiatric admission (pre‐admission offenders) and those who had started after it (post‐admission offenders). Our hypothesis was that such adverse childhood factors would be more prevalent in the pre‐admission offenders.Method Retrospective interview and records case–control study of all first high security hospital admissions diagnosed with schizophrenia in England 1972–2000. Risk factors were identified by multivariate logistic regression.Results 853 patients were pre‐ and 741 post‐admission offenders. Our hypothesis was confirmed in that factors associated with pre‐admission offending were paternal criminal convictions, larger family size, and younger age at first use of illicit drugs, on first smoking cigarettes, and at maternal separation. There were differences too in pre‐high security hospital treatment: pre‐admission offenders had been younger at first court appearance and had more criminal justice system disposals, post‐admission offenders were younger at first ever psychiatric hospital admission and more often hospitalized.Conclusions While early offending among people with schizophrenia may delay treatment, making the distinction between pre‐admission and post‐admission offending may be useful in understanding the aetiology of the offending, and establishment of such a history may help in targeting interventions supplementary to treatment specific for the psychosis.

Consideration of the blood supply of the ileocecal segment in valve preserving right hemicolectomy
Authors: Fernando E.D.P.S. , Deen K.I. 
Published: July 2009

AbstractThe ileocecal valve (ICV) is known to control the flow of chyme and to prevent bacterial colonization of the small intestine. Preservation of this segment during right hemicolectomy is likely to prevent loss of its function. This study aimed at evaluating the arterial supply of the ICV to help preserve the valve during right hemicolectomy. Fifty‐four fresh human cadavers (37 male, 17female; median age: 54 years, range: 18–90 years) were studied after relatives gave written, informed consent. At postmortem, 20 cm of terminal ileum with the ileocecal segment and up to 20 cm of ascending colon were removed en bloc with its mesentery and blood supply. The ileocolic artery was cannulated and injected with 10 ml of water‐soluble red dye under pressure. The arterial supply was dissected to demonstrate a pattern. In all, the ICV was supplied by the ileocolic artery, a branch of the superior mesenteric, which divided into an anterior and a posterior cecal artery. A marginal branch of the right colic was noted to contribute to ICV blood supply in only two (4%). Furthermore, study of the anastomosis at the ICV showed that the anterior cecal artery was present in all (100%), posterior cecal in 48 (89%), and recurrent ileal artery in 53 (98%). A rich anastomosis between vessels at the ICV; small “windows,” short tributaries, were seen in 38 (70%), whereas a poor anastomotic network at the ICV; large “windows,” long tributaries, between these vessels were seen in 12 (22%). In four (8%), we were unable to clearly determine between rich and poor anastomotic networks. Other variants included, absent posterior cecal artery in six (11%) and absent recurrent ileal artery in one (2%). The ICV has a predictable blood supply in the majority of patients. Preservation of the anterior cecal artery would ensure a vascularized ICV in right hemicolectomy. Clin. Anat. 22:712–715, 2009. © 2009 Wiley‐Liss, Inc.
Protective mechanisms of the common fibular nerve in and around the fibular tunnel: A new concept
Authors: El Gharbawy Ramadan M. , Skandalakis Lee J. , Skandalakis John E. 
Published: July 2009

AbstractThe most frequent site at which the common fibular nerve is affected by compression, trauma, traction, masses, and surgery is within and around the fibular tunnel. The aim of this study was to determine whether there were protective mechanisms at this site that guard against compression of the nerve. Twenty‐six lower limbs of 13 preserved adult cadavers (11 males and two females) were used. Proximal to the entrance of the tunnel, three anatomical configurations seemed to afford the required protection for the nerve: reinforcement of the deep fascia; tethering of the common fibular nerve to both the tendon of the biceps femoris and the reinforced fascia; and the particular arrangement of the deep fascia, fibular head, and soleus and gastrocnemius muscles. At the entrance of the tunnel, contraction of the first segment of fibularis longus muscle could afford the required protection. In the tunnel, contraction of the second and third segments of fibularis longus muscle could guard against compression of the nerve. The tough fascia on the surface of fibularis longus muscle and the fascial band within it, which have long been accused of compression of the nerve, may actually be elements of the protective mechanisms. We conclude that there are innate, anatomical protective mechanisms which should be taken into consideration when decompressing the common fibular nerve. To preserve these mechanisms whenever possible, the technique should be planned and varied according to the underlying etiology. Clin. Anat. 22:738–746, 2009. © 2009 Wiley‐Liss, Inc.

Enantioselective Nitroso‐Diels–Alder Reaction and Its Application for the Synthesis of (−)‐Peracetylated Conduramine A‐1
Authors: Jana Chandan Kumar , Grimme Stefan , Studer Armido 
Published: July 2009

AbstractCuI‐catalyzed enantioselective nitroso‐Diels–Alder reactions (NDA reactions) of 2‐nitrosopyridine with various dienes are presented. The [CuPF6(MeCN)4]/Walphos‐CF3 catalyst system is best suited to catalyze the NDA reaction of various dienes by using 2‐nitrosopyridine as a dienophile. In most of the cases studied, cycloadducts are obtained in quantitative yield with very good to excellent enantioselectivities. Based on DFT calculations, a model to explain the stereochemical outcome of the NDA reaction is presented. Finally, an efficient short synthesis of (−)‐peracetylated conduramine A‐1 by applying the enantioselective NDA reaction as a key step is described.
