RESUMO
BACKGROUND: Although Mirizzi syndrome is widely reported in literature, little is known about acute acalcholous cholecystitis determinig the findings of a Mirizzi syndrome. CASE PRESENTATION: We report a case of MRCP-confirmed Mirizzi syndrome in acute acalculous cholecystitis resolved by surgery. CONCLUSION: Acute acalcholosus cholecystitis determinig a Mirizzi Syndrome should be included in the Mirizzi classification as a type 1. Thus it could be useful to divide the type 1 in two entity (compression by stone and compression by enlarged gallbladder). Magnetic Resonance should be considered the preferred diagnostic tool in any case of Mirizzi syndrome suspicious.

The use of weight loss surgery is progressively increasing, and in recent years, restrictive bariatric surgery procedures have been more often used. Although thought to be associated with a lower incidence of post-operative side effects than malabsorpitive surgery, some cases of micronutrients deficiency have been reported because of an acquired thiamine deficiency; in this clinical setting, some cases of Wernicke encephalopathy (WE) have been described. Major determinants and predictors of this major neurological complication are currently unknown. The aim of this systematic review was to analyse literature data in order to address this issue. The main result of our systematic review was that persistent vomiting is the major determinant of WE in patients undergoing restrictive weight loss surgery. In addition, early thiamine supplementation can rapidly improve the clinical conditions, avoiding permanent deficiencies. On the other hand, given the wide variability of clinical and demographic characteristics, definite prognostic factors of WE occurrence and of clinical outcome cannot be identified. In conclusion, although our results are suggestive, further ad hoc prospective studies evaluating changes in micronutrients levels according to different types of surgery are needed.

Specific, sensitive, and rapid detection of quarantine and regulated plant pathogens is pivotal for the control of the diseases they cause. Here, we describe the PCR-based methods which have been developed for Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), quarantine plant pathogenic bacterium for EU and causal agent of bacterial wilt of Leguminous plants. These methods include an end-point and a real-time PCR test, and a LAMP assay. Their threshold analytical limits range from 100 to 10 fg of DNA template per reaction and are currently used worldwide for routine testing for Cff from laboratory to field scale.

INTRODUCTION: Glucose storage disease type IXa (GSD IXa) is an uncommon condition presenting with childhood onset hepatomegaly, growth retardation, and often, fasting ketosis and hypoglycemia. Despite its benign course, the lack of dietary counseling may favor uncontrolled weight gain. We investigated the efficacy of bariatric surgery in one 17 years old female suffering from GSD IXa and morbid obesity. PRESENTATION OF CASE: The diagnosis was GSD type IXa in a patient with a body mass index (BMI) of 45.5kg/m(2). Onset of hypoglycemia was reported twice each month. She was treated her implanting an adjustable gastric banding through laparoscopy. Three years after surgery the patient presents a BMI of 30.1kg/m(2) and an excess of weight loss (EWL) of 71.1%. Only once, following surgery, she had to deflate her band to allow a faster transit of food through her stomach, thus reaching a prompt euglycemic condition, due to an incoming hypoglycemic crisis. DISCUSSION: Laparoscopic adjustable gastric banding (LAGB) is one of the most used approaches to treat morbid obesity. It is a restrictive procedure unable to affect the absorption of any nutrient, presenting a very low intra and perioperative complication rate. In our GSD IXa patient, it offered a prompt modification of food intake restriction whenever requested, thus avoiding hypoglycemia. CONCLUSION: LAGB is effective in determining weight loss without inducing significant side effects or worsening hypoglycemia, in this morbid obese patient, suffering from GSD type IXa.
RESUMO
INTRODUCTION: The prevalence of obesity is rising progressively, even among elderly patients. Many studies investigated about safety and efficacy of bariatric surgery among aged obese patients. The objective of this review is to assess the benefits relative to risks of weight loss that may be obtained by performing two common bariatric procedures in obese elderly patient. MATERIALS AND METHODS: We retrospectively evaluated 10 morbid obese patients older than 60 years reaching 5 years of follow up who respectively underwent Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Adjustable Gastric Banding (LAGB). Eventual changes in comorbidities, weight loss, EWL% were investigated. RESULTS: Although LSG patients required a longer postoperative hospital stay than LAGB patients (p < 0.001), both procedures have shown to be safe and equally effective for weight loss achievement in elderly patients. Whereas all patients showed comorbidities resolution, no significant difference in weight loss between LAGB group and LSG group was found at 1 year (EWL% p = 0.87; BMI p = 0.32), 3 years (EWL% p = 0.62; BMI p = 0.79) and 5 years (EWL% p = 0.52; BMI p = 0.46) of follow up. CONCLUSIONS: Bariatric surgery is safe and effective to reach obesity related comorbidities resolution among elderly obese patients. Both LAGB and LSG determine a weight loss lesser than observed in a standard bariatric population. In this study LSG is significantly less cost effective than LAGB. Larger studies with longer follow up are however needed to evaluate the real impact of bariatric surgery on weight loss, resolution of comorbidities and improvement of quality of life in elderly obese patients.

Staple line leakage and bleeding are worrisome complications of laparoscopic sleeve gastrectomy (LSG). Solutions such as buttressing, oversewing or roofing the staple line with gelatin matrix have been proposed with controversial results. Because the use of fibrin sealant has shown a possible benefit in reducing the reoperation rate due to early complication in patients (pts) undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP), this solution has been tested in 100 consecutive pts undergoing LSG. A clinical trial has been performed on 100 consecutive pts. Exclusion criteria from the study were considered ASA IV pts, treated or untreated malignancies at any stage, steroids or FANS assumption, previous sovramesocolic surgery and conversion to open surgery. All pts were randomized to receive (group A, 50 pts) or to not receive (group B, 50 pts) 4 ml of human fibrin sealant (Tisseel™, Baxter(®) Deerfield, IL, USA) sprayed along the suture line. Primary endpoint was the incidence of postoperative complications: leaks, bleeding of the staple line or stenosis of the gastric remnant. Significance was assigned at a p level <0.05. By considering pts in group A vs. pts in group B our results shown no significant difference in fistulas or strictures occurrence (p = 0.2). Bleeding was significantly higher in patients not sprayed with sealant (group A vs. group B, 1/7, p = 0.03). This randomized trial has so far shown the use of fibrin sealant in LSG to significantly reduce postoperative bleeding. Although a trend in reducing leak occurrence emerges, it does not reach statistical significance.

AIM: To investigate the weight loss and glycemic control status [blood glucose, hemoglobin A1c (HbA1c) and hypoglycaemic treatment]. METHODS: The primary risk factor for type 2 diabetes is obesity, and 90% of all patients with type 2 diabetes are overweight or obese. Although a remarkable effect of bariatric surgery is the profound and durable resolution of type 2 diabetes clinical manifestations, little is known about the difference among various weight loss surgical procedures on diabetes remission. Data from patients referred during a 3-year period (from January 2009 to December 2011) to the University of Naples "Federico II" diagnosed with obesity and diabetes were retrieved from a prospective database. The patients were split into two groups according to the surgical intervention performed [sleeve gastrectomy (SG) and mini-gastric bypass (MGB)]. Weight loss and glycemic control status (blood glucose, HbA1c and hypoglycaemic treatment) were evaluated. RESULTS: A total of 53 subjects who underwent sleeve gastrectomy or mini-gastric bypass for obesity and diabetes were screened for the inclusion in this study. Of these, 4 subjects were excluded because of surgical complications, 7 subjects were omitted because young surgeons conducted the operations and 11 subjects were removed because of the lack of follow-up. Thirty-one obese patients were recruited for this study. A total of 15 subjects underwent SG (48.4%), and 16 underwent MGB (51.6%). After adjusting for various clinical and demographic characteristics in a multivariate logistic regression analysis, high hemoglobin A1c was determined to be a negative predictor of diabetes remission at 12 mo (OR = 0.366, 95%CI: 0.152-0.884). Using the same regression model, MGB showed a clear trend toward higher diabetes remission rates relative to SG (OR = 3.780, 95%CI: 0.961-14.872). CONCLUSION: Although our results are encouraging regarding the effectiveness of mini-gastric bypass on diabetes remission, further studies are needed to provide definitive conclusions in selecting the ideal procedure for diabetes remission.
