Endoscopic bougienage of benign anastomotic strictures in patients after esophageal resection: the effect of the extent of stricture on bougienage results

DISEASES OF THE ESOPHAGUS, Issue 6 2008
G. Marjanovic
SUMMARY., The aim of our retrospective study was to determine the incidence of benign anastomotic strictures (BAS) in patients after esophageal resection and to examine the influence of the extent of BAS on the results of bougienage therapy. From January 2001 to July 2006, 79 patients at risk of BAS development were included in the study. BAS was diagnosed with a median delay of 8 weeks (4,26) postoperative in 23 patients (29%). A median of 4 bougienage sessions (2,20) was needed for success (success rate 100%). The mean follow-up time was 22 months [range 3,47]. There were no late recurrences of BAS. Five patients had an anastomosis diameter <5.5 mm and 14 patients >5.5 mm. There was no difference in median number of bougienage procedures in these subgroups (4.5 [2,9] vs. 4 [2,20]). Patients who presented with BAS earlier than 6 weeks postoperative had more procedures (median 8 [2,20] vs. 4 [2,9]) than those presenting later. Patients in whom first bougienage was possible to only 16 mm diameter needed more procedures than patients in whom first dilation was possible to more than 16 mm (median 5.5 [3,20] vs. 3 [2,9]). In conclusion, both early BAS development and the diameter of bougienage at first endoscopy, but not the extent of stricture, seem to be predictive factors for longer bougienage therapy. In order to influence the BAS formation early, we now routinely examine every patient after esophageal resection endoscopically in the 6th postoperative week. [source]


Paediatric lap-belt injury: A 7 year experience

EMERGENCY MEDICINE AUSTRALASIA, Issue 1 2006
Michael Shepherd
Abstract Objective:, To highlight the injuries that result from lap-belt use and make recommendations for prevention, the recent experience of a regional paediatric trauma centre was reviewed. Methods:, Retrospective review of admissions to Starship Children's Hospital from 1996 to 2003, with significant injury following involvement in a motor vehicle crash, while wearing a lap-belt. Patients were identified from two prospectively collected databases and discharge coding data. Results:, In total, 19 patients were identified over the 7 year period. The morbidity sustained includes 15 patients with hollow viscus injury, 13 laparotomies, 7 spinal fractures, 2 paraplegia and 1 fatality. A total of 11 patients required laparotomy with a median delay of 24 h. Of patients in the present series, 58% were aged less than 8 years and thus were inappropriately restrained. Conclusions:, Lap-belt use can result in a range of life-threatening injuries or permanent disability in the paediatric population. The incidence of serious lap-belt injury does not appear to be decreasing. Morbidity and mortality could be reduced by the use of three-point restraints, age appropriate restraints and booster seats.

Early treatment after a symptomatic event is not associated with an increased risk of stroke in patients undergoing carotid stenting

EUROPEAN JOURNAL OF NEUROLOGY, Issue 1 2008
K. Gröschel
A recently symptomatic carotid artery stenosis carries a high risk of subsequent ischaemic events and thus requires rapid treatment. We investigated the influence of the time delay between the last symptomatic event of a carotid stenosis and subsequent carotid artery stenting (CAS) with respect to the combined 30-day outcome of stroke and death. In a group of 320 patients undergoing CAS the median delay before the intervention was 19 days (interquartile range 10,36) and the combined 30-day complication rate was 8.4%. Time delay was not significantly associated with peri-procedural complications, regardless of whether this variable was dichotomized (<14 days and ,14 days), separated into interquartile ranges or analysed as a continuous variable. Our results indicate that early CAS is not associated with an increased complication rate in patients with a recently symptomatic carotid stenosis. Thus, if CAS has been selected as the treatment modality for a patient, it should be performed as soon as possible to maximize the benefit of the intervention in reducing the risk of stroke.

Incidence and odds ratio of appendicitis as first manifestation of colon cancer: A retrospective analysis of 1873 patients

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 11 2006
Hung-Wen Lai
Abstract Background and Aim:, Obstruction of the lumen of the appendix is the major cause of appendicitis. Tumors could obstruct this lumen and cause appendicitis in the elderly. The association between appendicitis and colon cancer has not been sufficiently investigated, and this study was designed to clarify this association. Methods:, This was a retrospective study. Patients diagnosed with acute appendicitis from January 1998 to December 2003 at the Taipei Veterans General Hospital were surveyed. Patients found to have colon cancers immediately or subsequently after appendectomy were included and analyzed. Results:, A total of 1873 patients were diagnosed as having appendicitis of whom 16 were found to have colon cancer. The incidence of appendicitis associated with colon cancer was 0.85%. The time from appendectomy to the recognition of colonic cancer was at a median delay of 5.8 months. From the Taiwan Cancer Research Annual Report, the incidence of colon cancer was 31.91/100 000 in the year 2000. The odds ratio of colon cancer incidence had a 38.5-fold increase among patients older than 40 with acute appendicitis. Conclusions:, In patients over 40 years who present with symptoms of acute appendicitis the possibility of a coexistent colonic neoplasm should always be kept in mind. These patients should undergo colonoscopy 6 weeks after surgery to exclude the possibility of a coexistent colorectal cancer. [source]


Chronic hepatitis: Role of diffusion-weighted imaging and diffusion tensor imaging for the diagnosis of liver fibrosis and inflammation

JOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 1 2008
Bachir Taouli MD
Abstract Purpose To determine the diagnostic performance of liver apparent diffusion coefficient (ADC) measured with conventional diffusion-weighted imaging (CDI) and diffusion tensor imaging (DTI) for the diagnosis of liver fibrosis and inflammation. Materials and Methods Breathhold single-shot echo-planar imaging CDI and DTI with b-values of 0 and 500 second/mm2 was performed in 31 patients with chronic liver disease and 13 normal volunteers. Liver biopsy was performed in all patients with liver disease with a median delay of two days from MRI. Fibrosis and inflammation were scored on a 5-point scale (0,4). Liver ADCs obtained with CDI and DTI were compared between patients stratified by fibrosis stage and inflammation grade. Receiver operating characteristic (ROC) curve analyses were conducted to evaluate the utility of the ADC measures for prediction of fibrosis and inflammation. Results Patients with liver fibrosis and inflammation had significantly lower liver ADC than subjects without fibrosis or inflammation with CDI and DTI. For prediction of fibrosis stage , 1 and stage , 2, area under the ROC curve (AUC) of 0.848 and 0.783, sensitivity of 88.5% to 73.7%, and specificity of 73.3% to 72.7% were obtained, for ADC ,1.40 × 10,3 mm2/second and ,1.30 × 10,3 mm2/second (using CDI), respectively. For prediction of inflammation grade , 1, AUC of 0.825, sensitivity of 75.0%, and specificity of 78.6% were obtained using ADC , 1.30 × 10,3 mm2/second (using CDI). CDI performed better than DTI for diagnosis of fibrosis and inflammation. Conclusion Liver ADC can be used to predict liver fibrosis and inflammation with acceptable sensitivity and specificity. J.

Conversion to sirolimus-based immunosuppression in maintenance liver transplantation patients

LIVER TRANSPLANTATION, Issue 5 2007
Isabelle Morard
Sirolimus (SRL) has been proposed to replace calcineurin inhibitors (CNI) in case of CNI-induced toxicity. The aim of this study was to evaluate the efficacy and safety of conversion from CNI to SRL in maintenance liver transplantation (LT) patients. Between 2002 and 2006, conversion was performed in 48 patients (17 female, 31 male; mean age 57 ± 10 yr) after a median delay of 19.4 months (range 0.2,173 months) after LT. Indication for conversion was renal impairment (RI) (78%), CNI neurotoxicity (13%), or post-LT cancer (9%). Median follow-up was 22.6 ± 11 months. Median SRL dosage and trough levels were 2.4 ± 1.3 mg and 8.1 ± 2.7 ,g/L. Immunosuppression consisted of SRL alone (33%), or SRL + mycophenolate mofetil (MMF) (39%), SRL + prednisone (15%), SRL + CNI (4%), or SRL + MMF + prednisone (8%). Mean glomerular filtration rate (GFR) improved from 33 to 48 mL/minute in patients with severe RI (P = 0.022) and from 56 to 74 mL/minute in patients with moderate RI (P = 0.0001). After conversion, main complications were albuminuria (36%), hyperlipidemia (49%), dermatitis (14%), edema (14%), oral ulcers (12%), joint pain (4%), infection (2%), and pneumonia (2%). Acute rejection (AR) occurred in 17% of the patients. SRL was withdrawn in 17% of the patients. In conclusion, conversion from CNI to SRL is safe and is associated with significant renal function improvement. Liver Transpl 13:658,664, 2007. © 2007 AASLD. [source]


Conversion from mycophenolate mofetil to enteric-coated mycophenolate sodium in liver transplant patients presenting gastrointestinal disorders: A pilot study

LIVER TRANSPLANTATION, Issue 9 2006
Jérôme Dumortier
Gastrointestinal (GI) disorders are one of the main adverse events in patients treated by mycophenolic acid (MPA). The aim of this prospective study was to evaluate the effect of conversion from mycophenolate mofetil (MMF) to enteric-coated mycophenolate sodium (EC-MPS) in liver transplant patients presenting GI side-effects Since January 2003, stable liver transplant patients receiving MMF and presenting GI disorders, without evidence of other origin than MMF were enrolled. Conversion was performed without a washout period at an equimolar daily dosage. Thirty-six patients were included after a median delay of 45 months after liver transplantation (LT) (16 women and 20 men, median age of 47 years). Diarrhoea was the main clinical symptom (n = 28, 77.7%). At the time of inclusion, patients were treated with MMF since 18 months (range 3-28) and GI disorders were known for 9 months (range 3-12). After a median follow-up of 12 months after conversion, GI disorders were resolved in 20 patients (55%), improved in 6 patients (17%) and not modified or worsened in 10 patients (28%). Our results strongly suggest that conversion from MMF to EC-MPS in liver transplant patients can improve gastrointestinal disorders in a majority of the patients, and therefore might be considered as the best therapeutic option.

Efficacy and tolerability of rituximab with or without PEGylated interferon alfa-2b plus ribavirin in severe hepatitis C virus,related vasculitis: A long-term followup study of thirty-two patients

ARTHRITIS & RHEUMATISM, Issue 8 2009
Benjamin Terrier
Objective To report on the long-term followup of a cohort of patients with hepatitis C virus (HCV),related vasculitis treated with rituximab with or without PEGylated interferon alfa-2b (PEG,IFN alfa-2b) plus ribavirin. Methods The study group comprised 32 HCV RNA,positive patients with HCV-related vasculitis: 20 patients were treated with rituximab and PEG,IFN alfa-2b (9 of whom had not previously received antiviral treatment and 11 of whom had experienced disease resistance to or relapse with antiviral treatment), and 12 antiviral-intolerant patients were treated with rituximab alone. Results Treatment with rituximab and PEG,IFN alfa-2b plus ribavirin induced a complete clinical response and a partial clinical response in 80% and 15% of patients, respectively, a complete immunologic response and a partial immunologic response in 67% and 33% of patients, respectively, and a sustained virologic response in 55% of patients. Treatment with rituximab alone induced a complete clinical response and a partial clinical response in 58% and 9% of patients, respectively, and a complete immunologic response and a partial immunologic response in 46% and 36% of patients, respectively. B cell depletion was achieved in 96% of patients, and B cell recovery began after a median delay of 12 months. After a mean ± SD followup period of 23 ± 12 months, 22% of patients experienced a clinical relapse, and 34% of patients experienced an immunologic relapse. All relapses were associated with the absence of virologic control, and 78% of relapses were associated with B cell recovery. Six patients were re-treated with rituximab. All 6 of these patients had a complete clinical response, 50% had a complete immunologic response, and 50% had a partial immunologic response. Rituximab was well tolerated overall. Conclusion Rituximab is an effective treatment of severe and/or refractory HCV-related vasculitis. Relapses were consistently associated with the absence of virologic control. The clinical and immunologic efficacy of rituximab after repeated infusion appeared to be the same as that observed after induction therapy. [source]


Practices for prevention, diagnosis and management of postpartum haemorrhage: impact of a regional multifaceted intervention

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2009
E Audureau
Objective, To evaluate the effectiveness of a multifaceted intervention on practices for prevention, diagnosis and management of postpartum haemorrhage (PPH) and on the prevalence of major PPH in a French perinatal network. Design, Quasi-experimental before-and-after survey. Setting, All maternity units (n = 19) of a French administrative region, operating as a perinatal network. Sample, One representative sample of all women delivering in the network, one representative sample of women with PPH deliveries and an exhaustive sample of women with major PPH. Methods, The multifaceted intervention took place between February 2003 and March 2004. Information was retrospectively collected for two periods, 2002 (before the intervention) and 2005 (after). Main outcome measures, Practices for prevention, diagnosis and management of PPH and prevalence of major PPH. Results, After the intervention, the pharmacological prevention of PPH increased from 58.8% to 75.9% of vaginal deliveries (P < 10,4), and the use of blood collecting bags from 3.9% to 76.3% (P < 10,4), but initial PPH management did not change significantly. However, the median delay for second-line pharmacological treatment was significantly shortened [from 80 min (35,130) in 2002 to 32.5 min (20,75) in 2005]. An increase was observed in the use of surgery for PPH (0.06% versus 0.12% of deliveries; P = 0.03) and in blood transfusions (0.18% versus 0.33%; P = 0.01). The prevalence of major PPH did not change (0.80% versus 0.86% of deliveries; P = 0.62). Conclusions, The intervention was effective at improving PPH-related preventive and diagnostic practices in a perinatal network. Improving management practices and reducing the prevalence of major PPH might require a different intervention design. [source]


Trends in melanoma epidemiology suggest three different types of melanoma

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2007
D. Lipsker
Summary Background It has been suggested that the incidence of thin melanomas but not of thick tumours is rising in fair-skinned populations, although the reason for this discrepancy is not understood. Objectives To describe temporal trends in melanoma epidemiology in a limited part of France in order to confirm this observation and to provide an explanation. Methods This is a retrospective population- and academic centre-based study in which all melanomas diagnosed in the department of the Bas-Rhin, France between January 1980 and December 2004 were included. Results The study included 2094 melanomas diagnosed in 2020 patients. There was a steady increase in incidence of thin (< 1 mm) melanomas, mainly located on the trunk, and to a lesser extent in the head and neck region, in both sexes, and of intermediate (1,2 mm) melanomas in men. The incidence of intermediate melanomas in women and of thick (> 2 mm) melanomas, as well as mortality related to melanoma, remained stable. There was a steady decline of mean and median Breslow thickness. The 12 months median delay to diagnosis of thick tumours was significantly shorter than the 24 months delay to diagnosis of thin tumours. Conclusions Temporal trends suggest the existence of three unrelated types of melanoma: type I, thick melanomas, with stable incidence; type II, thin melanoma with a steady and important increase in incidence, mainly located on the trunk; and type III, melanoma with a slower increase in incidence, mainly located on the head and neck region.
