Objective The purpose of this study was to asses the value of intraoperative cone-beam CT (O-arm) and stereotactic navigation for the insertion of anterior odontoid screws.Materials and methods this was a retrospective review of patients receiving surgical treatment for traumatic odontoid fractures during a period of 18 months. Procedures were guided with O-arm assistance in all cases. The screw position was verified with an intraoperative CT scan. Intraoperative and clinical parameters were evaluated. Odontoid fracture fusion was assessed on postoperative CT scans obtained at 3 and 6 months' follow-upResults Five patients were included in this series; 4 patients (80%) were male. Mean age was 63.6 years (range 35-83 years). All fractures were acute type ii odontoid fractures. The mean operative time was 116 minutes (range 60-160 minutes). Successful screw placement, judged by intraoperative computed tomography, was attained in all 5 patients (100%). The average preoperative and postoperative times were 8.6 (range 2-22 days) and 4.2 days (range 3-7 days) respectively. No neurological deterioration occurred after surgery. The rate of bone fusion was 80% (4/5).Conclusion Although this initial study evaluated a small number of patients, anterior odontoid screw fixation utilizing the O-arm appears to be safe and accurate. This system allows immediate CT imaging in the operating room to verify screw position. © 2014 Sociedad Española de Neurocirugía. © 2014 Sociedad Española de Neurocirugía.

Home enteral nutrition (HEN) is the choice for patients who can not mantain oral intake but have a functioning gastrointestinal tract when it isn't justify keeping the patient in the hospital. The results of the HEN registry of the NADYA group in 2010 shows information related to the enteral acces route: 51% of the cases used nasogastric tubes, 27% gastrostomies, 10% oral route and 3% jejunostomies. Placement of a needle catheter jejunostomy is recommended for candidates for enteral nutrition undergoing major abdominal surgery, but publications about long-term use of this acces are scarce. We report same cases of patients whom the selected enteral acces was surgical jejunostomy. They represents the 1,14% of our patients with HEN at this moment, with a mean dwelling time of 210 ± 222 days. There has been frequent complications, but they were sligh.

Background: The development of specific screening programs for individuals with a family history of colorectal cancer (CRC) is a priority. This study evaluates the diagnostic performance of serum soluble CD26 (sCD26) in family-risk individuals and compares this marker with the faecal immunochemical test for the detection of advanced neoplasia (AN) (CRC or advanced adenomas; AA). Methods: Five hundred and sixteen asymptomatic individuals with at least one first-degree relative with CRC were included. Serum sCD26 was measured in all the individuals who also underwent a colonoscopy (53 AA and four cancer cases were found) and a faecal immunochemical test. Results: Setting specificity to 90% and 95%, respectively, sCD26 showed a sensitivity of 39.6% and 28.3% for AA, and of 42.1% and 28.1% for AN. The combination of sCD26 and the faecal test detected AA and AN with a 52.8% and 56.1% sensitivity, corresponding to 93.5% specificity. Conclusions: The combination of serum sCD26 and the faecal blood test could result a valuable strategy for detecting AN in familial-risk CRC screening. © 2015 Cancer Research UK.

The levonorgestrel (LNG)-releasing intrauterine device (IUD) is a long-acting, progestin-only contraceptive method. The effect of this method is mainly local but systemic side effects sometimes occur because of the androgenic activity of LNG. We report the case of a woman who developed hidrosadenitis suppurativa after insertion of an LNG-IUD, which was resolved by removal of the device. Dermatologists should inquire about the use of LNG as a contraceptive method in women with this cutaneous disease. © 2012 SEGO.

Background/objectives Cachexia affects ∼80% of pancreatic cancer patients. An international consensus defines cachexia as an ongoing loss of skeletal muscle mass (sarcopenia) with or without loss of fat, which impairs body functioning and cannot be reversed by conventional nutritional measures. Weight loss percentage and elevated inflammation markers have been employed to define this condition earlier. This review aimed to assess the prevalence and consequences of cachexia and sarcopenia on survival in patients with pancreatic ductal adenocarcinoma. Methods The systematic review was performed by searching the articles with preset terms published in PubMed and Cochrane Database until December 2013. After identifying relevant titles, abstracts were read and eligible articles data retrieved on preformatted sheets. The prevalence and impact of sarcopenia/cachexia on survival was evaluated. Results In total 1145 articles were retrieved, only 10 were eligible. Definitions of cachexia and sarcopenia were heterogeneous. In patients with normal weight (BMI 18.5-24.9 kg/m2) the prevalence of sarcopenia ranged from 29.7 to 65%. In overweight or obese patients (BMI >25 kg/m2) were 16.2%-67%. Sarcopenia alone was not demonstrated to be an independent factor of decreased survival, although obese sarcopenic patients were shown to have significantly worse survival in two studies. Conclusions Impact of cachexia and sarcopenia on survival in pancreatic ductal adenocarcinoma is currently understudied in the available literature. Definitive association between cachexia and survival cannot be drawn from available studies, although weight loss and sarcopenic obesity might be considered as poor prognostic factors. Further prospective trials utilizing the consensus definition of cachexia and including other confounding factors are needed to investigate the impact of cachexia and sarcopenia on survival in pancreatic adenocarcinoma. © 2014 IAP and EPC.
