Abstract
Epidermoid cysts are rare lesions that can occur anywhere in the body. They are associated with elevated serum levels of CA 19-9. The spleen represents the most common site of intra-abdominal localisation. Only two cases of diaphragmatic epidermoid cyst are reported in the literature. We present the case of a 61-year-old woman with a small suprasplenic subdiaphragmatic cyst discovered during the investigation of left flank pain. The establishment of an adequate diagnosis was challenging due to the difficulty in specifying the exact localisation of the cyst, the extremely elevated CA 19-9 level of 19,000 and the high uptake on 18-fluoro-2-deoxy-D-glucose positron emission tomography. The definitive diagnosis followed complete surgical excision. Intra-abdominal epidermoid cysts are usually discovered incidentally on imaging for another reason. The cyst is lined by squamous epithelium responsible for the secretion of CA 19-9. The elevation of serum CA 19-9 is due to small rupture or increased intraluminal pressure followed by diffusion to the bloodstream. Surgery with en-bloc resection represents the optimal treatment to avoid any risk of recurrence. The definitive diagnosis is established by demonstrating positive immunohistopathological staining of epithelial cell to CA 19.9.

Abstract
PURPOSE To retrospectively assess the clinical utility in ureteroscopy (URS) planning of radiological parameters as predictor of stone-free status after a single flexible ureteroscopy. MATERIAL Sixty-seven patients with renal stones treated by flexible URS were retrospectively evaluated. To assess the clinical utility of radiological parameters, relationships between stone-free (SF) status and stone burden (maximal diameter, calculated area, calculated volume, cumulative diameter, and tridimentionnal volume [V3D]) were analyzed using the area under the receiver operating characteristics curve and logistic regression. RESULTS Maximal diameter (AUC=0.75), calculated area (AUC 0.79), calculated volume (AUC=0.79), cumulative diameter (AUC=0.80) and tridimensional volume (AUC=0.82) revealed ability to predict SF status after URS. CONCLUSION Stone burden evaluation is critical in predicting SF status after a single URS. Planar and volumetric measurements showed equal ability to predict SF status. V3D is more accurate but diameter measurement remains easier in clinical practice. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVE This study investigates the prevalence of different types of childhood adversities (CA) and posttraumatic stress disorder (PTSD) in female patients with Fibromyalgia or Chronic Widespread Pain (FM/CWP) compared to patients with Functional Dyspepsia (FD) and achalasia. In FM/CWP, we also investigated the association between CA and PTSD on the one hand and pain severity on the other. METHODS Patient samples consisted of 154 female FM/CWP, 83 female FD and 53 female achalasia patients consecutively recruited from a tertiary care hospital. Well-validated self-report questionnaires were used to investigate CA and PTSD. RESULTS Forty-nine per cent of FM/CWP patients reported at least 1 type of CA, compared to 39.7% of FD patients and 23.4% of achalasia patients (p < 0.01). The prevalence of CA did not differ significantly between FM/CWP and FD, but both groups had a higher prevalence of CA compared to both achalasia and healthy controls (p < 0.01). FM/CWP patients were six times more likely to report PTSD than both FD (p < 0.001) and achalasia (p < 0.001) patients. CONCLUSION In FM/CWP, PTSD comorbidity, but not CA, was associated with self-reported pain severity and PTSD severity mediated the relationship between CA and pain severity. In summary, the prevalence of CA is higher in FM/CWP compared to achalasia, but similar to FD. However, PTSD is more prevalent in FM/CWP compared to FD and associated with higher pain intensity in FM/CWP. SIGNIFICANCE As expected and has been shown in other functional disorders, we found elevated levels of childhood adversity in FM/CWP patients. Results of this study however suggest that the impact of childhood adversity (i.e. whether such events have led to the development of PTSD symptoms), rather than the mere presence of such adversity, is of crucial importance in FM/CWP patients. Screening for PTSD symptoms should be an essential part of the assessment process in patients suffering from FM/CWP, and both prevention and intervention efforts should take into account PTSD symptoms and their impact on pain severity and general functioning.

Abstract
The role of diagnostic imaging in chronic and inflammatory pancreatitis is to detect structural changes of the ducts and pancreatic parenchyma, to assess the functional integrity of the gland, to detect associated complications, and to assist in management. These goals may be achieved using helical CT and MR imaging with secretin stimulation. In this review, the advantages of each technique are discussed and illustrated.

Abstract
AIM The aim of this study was to evaluate the role of the 18F-FDG-PET in the preoperative evaluation of patients with oesophageal or gastro-oesophageal junction (GEJ) cancer and to define its impact on therapeutic management. PATIENTS AND METHODS This study included 58 patients with biopsy proven oesophageal or GEJ cancer who underwent PET in addition to the conventional diagnostic work-up. The sensitivity, specificity and accuracy of CT and PET were calculated for detection of tumour and distant metastases. RESULTS The sensitivity, specificity and accuracy of tumour detection were, respectively, 84, 100 and 84% for CT and 87, 100 and 87% for PET (p=ns). PET permitted detection of distant metastases, which were not seen on CT in seven patients. In two patients, a second primary tumour was detected on PET. CONCLUSIONS The sensitivity of PET for loco regional lymph nodes detection is low. The major clinical impact is the detection of distant metastases.

Abstract
BACKGROUND We investigated the feasibility, safety, and efficacy of laparoscopic antireflux surgery (LARS) after failure of Enteryx injection in the lower esophageal sphincter for the treatment of gastroesophageal reflux disease (GERD). METHODS Four patients underwent LARS after failure of Enteryx injection. Particular care was taken during the procedure to identify unusual material or fibrosis. RESULTS All patients underwent LARS successfully. In three patients, tight adhesions with fibrous tissues and black foreign material were observed around the esophagus. No complications occurred during the procedures. The postoperative period was uneventful and functional results were excellent. CONCLUSION LARS following Enteryx injection is feasible. Careful dissection is mandatory to avoid operative complications. Both techniques may be considered as options for treating GERD.

Abstract
Radiofrequency ablation (RFA) recently emerged as an efficient and safe local ablative method to treat unresecable liver tumours. Currently however, the full spectrum of potential complications of RFA remains undetermined. We report a case of severe biliary complication, associating main bile duct stricture and biliary pleural fistula, arising after extensive RFA for unresectable liver metastasis of central location. Treatment consisted of external drainage of the pleural effusion and internal endoscopic drainage via a biliary stenting. This description of a life-threatening complication emphazises the need to better knowledge of the contraindications of RFA, particularly for the treatment of large tumours at proximity of main bile ducts.

Abstract
BACKGROUND The purpose of this report is to describe the radiologic appearances of laparoscopic adjustable silicone gastric banding (LASGB), a new surgical treatment for morbid obesity. In this procedure, a silicone band is fastened around the fundus, delimitating a small proximal gastric pouch and stoma. The inner surface of the band is inflatable and connected by a thin silicone tube to an access port. This allows postoperative stoma size adjustment by puncturing the port and injecting or withdrawing saline solution. METHODS One hundred eighty patients underwent LASGB. A radiologic study protocol was established and performed in all patients, including preoperative double-contrast upper gastrointestinal (GI) series and single-contrast upper GI series on the first postoperative day and 1 month after surgery. Radiologic evaluation was also performed at each band adjustment and in case of persistent vomiting or inadequate weight loss. RESULTS Postoperative stoma adjustment was performed in all patients. The optimal volume of saline was 1-4.5 mL. Percutaneous puncture of the port was impossible in three patients because of an inverted port. We observed 15 cases of pouch dilatation with stomal obstruction requiring reoperation. There were also nine cases of spontaneous band deflation caused by leaking reservoir in five cases and by disconnection between the connecting tube and the port in the other four cases. CONCLUSIONS Because radiologic evaluation is necessary after surgery and for band adjustments, radiologists are involved in the postoperative follow-up and may be asked to perform those adjustments themselves.

Abstract
OBJECTIVE A randomised, controlled clinical trial was performed to study the long-term effect of gradual withdrawal from benzodiazepines on the daily functioning of residents of homes for the elderly. The planned sample size was not achieved due to recruitment and follow-up problems. RESULTS The results in this small sample nevertheless suggest that gradual withdrawal from benzodiazepines is possible in residents of homes for the elderly, and that it can have a positive effect on their daily functioning. No major withdrawal symptoms were observed, although there was a decrease in sleep quality during withdrawal. CONCLUSION The findings are promising for further research, but researchers should anticipate the problems inherent in executing a trial with institutionalised elderly subjects.

Abstract
A fusion protein between beta-galactosidase and the amino-terminal domain of amyloid precursor protein (APP) was used as an immunogen for the production of monoclonal antibodies. One of these antibodies, the 5D12 monoclonal antibody, labeled the neurofibrillary tangles (NFT) by immunohistochemistry, as well as isolated paired helical filaments (PHF) in electron microscopy. In immunoassay, the ascitic fluid produced by the 5D12 clone was demonstrated to contain a high titer of antibodies to heat-stable microtubule associated proteins (MAPs). By immunoblotting, the proteins recognized in heat-stable MAPs were found to correspond to tau proteins. The 5D12 antibody recognized normal tau isolated from rat and human brain homogenates, and PHF-tau isolated from the brain of patients with Alzheimer's disease (AD). By immunoblotting, the 5D12 antibody also recognized the full-length recombinant tau protein but not the fusion protein used as an immunogen. The immunoreactivity of the 5D12 antibody with tau was completely abolished when the half-carboxy domain of tau, containing the tubulin-binding repeats, was removed. This study demonstrates that the use of the amino-terminal domain of APP as an immunogen led to the generation of a monoclonal antibody to the half-carboxy domain of tau.
