Is proliferative colonic disease presentation changing?

AIM: To compare the site, age and gender of cases of colorectal cancer (CRC) and polyps in a single referral center in Rome, Italy, during two periods.METHODS: CRC data were collected from surgery/pathology registers, and polyp data from colonoscopy reports. Patients who met the criteria for familial adenomatous polyposis, hereditary non-polyposis colorectal cancer syndrome or inflammatory bowel disease were excluded from the study. Overlap of patients between the two groups (cancers and polyps) was carefully avoided. The χ² statistical test and a regression analysis were performed.RESULTS: Data from a total of 768 patients (352 and 416 patients, respectively, in periods A and B) who underwent surgery for cancer were collected. During the same time periods, a total of 1693 polyps were analyzed from 978 patients with complete colonoscopies (428 polyps from 273 patients during period A and 1265 polyps from 705 patients during period B). A proximal shift in cancer occurred during the latter years for both sexes, but particularly in males. Proximal cancer increased > 3-fold in period B compared to period A in males [odds ratio (OR) 3.31, 95%CI: 2.00-5.47; P < 0.0001). A similar proximal shift was observed for polyps, particularly in males (OR 1.87, 95%CI: 1.23-2.87; P < 0.0038), but also in females (OR 1.62, 95%CI: 0.96-2.73; P < 0.07).CONCLUSION: The prevalence of proximal proliferative colonic lesions seems to have increased over the last decade, particularly in males.     

Effectiveness of Nutritional Supplementation on Muscle Mass in Treatment of Sarcopenia in Old Age: A Systematic Review

BackgroundMuch interest has been focused on nutritional treatment of sarcopenia, loss of muscle mass and performance associated to aging; however, its benefits are unclear.ObjectiveTo analyze the relevance of nutritional treatment of sarcopenia and assess the effects of supplementation on muscle mass and function within the aged population.MethodsWe searched Medline and the Cochrane Library for controlled trials published between 1991 and 2012. We have assessed the quality, type of intervention, the cohort used, the way muscle mass was measured, and the outcomes of the various studies.ResultsWe have included 17 studies, with a total of 1287 patients, aged between 65 and 85 on average. An improvement in muscle mass was proven, whether measured with bioelectrical impedance analysis or dual energy x-ray absorptiometry, and an improvement in strength was also proven.ConclusionNutritional supplementation is effective in the treatment of sarcopenia in old age, and its positive effects increase when associated with physical exercise. The main limitation of this treatment is lack of long-term adherence. A healthy diet associated with a physically active lifestyle and possibly with aerobic exercise are the basis of healthy aging, which is the aim of all doctors treating aged people must seek.     

Achilles tendon problems: Not just an orthopaedic issue

Purpose. To review the current concepts on Achilles tendon involvement in various pathological conditions.

Method. A literature search was conducted to trace relevant literature on Achilles tendon problems in general pathologies.

Results. The Achilles tendon can be involved in inflammatory and autoimmune conditions, genetically determined collagen abnormalities, infectious diseases, tumours, and neurological conditions which are not of a primary surgical nature.

Conclusions. Although Achilles tendon problems are classically considered frequent in active individuals from overuse or a single acute episode, problems in the Achilles tendon can be a consequence of several conditions.     

Omentopexy with Glubran®2 for reducing complications after laparoscopic sleeve gastrectomy: results of a randomized controlled study

Background

Gastric fistulas, bleeding, and strictures are commonly reported after laparoscopic sleeve gastrectomy (LSG), that increase morbidity and hospital stay and may put the patient’s life at risk. We report our prospective evaluation of application of synthetic sealant, a modified cyanoacrylate (Glubran®2), on suture rime, associated with omentopexy, to identify results on LSG-related complications.

Methods

Patients were enrolled for LSG by two Bariatric Centers, with high-level activity volume. Intraoperative recorded parameters were: operative time, estimated intraoperative bleeding, conversion rate. We prospectively evaluated the presence of early complications after LSG during the follow up period. Overall complications were analyzed. Perioperative data and weight loss were also evaluated. A control group was identified for the study.

Results

Group A (treated with omentopexy with Glubran®2) included 96 cases. Control group included 90 consecutive patients. There were no differences among group in terms of age, sex and Body Mass Index (BMI). No patient was lost to follow-up for both groups. Overall complication rate was significantly reduced in Group A. Mean operative time and estimated bleeding did not differ from control group. We observed three postoperative leaks in Group B, while no case in Group A (not statistical significancy). We did not observe any mortality, neither reoperation. Weight loss of the cohort was similar among groups. In our series, no leaks occurred applying omentopexy with Glubran®2.

Conclusion

Our experience of omentopexy with a modified cyanoacrylate sealant may lead to a standardized and reproducible approach that can be safeguard for long LSG-suture rime.

Relationship between plasma insulin and left ventricular mass in normotensive participants of the Gubbio Study

BACKGROUND: There is substantial but not conclusive evidence that insulin resistance is related to left ventricular mass (LVM) in hypertensive individuals. To what extent this association is mediated by the relationship between plasma insulin and body size and build is still debated, and is poorly explored in nonhypertensive people. OBJECTIVE: To explore the relationship between insulin or insulin resistance and LVM in a population-based sample of nonhypertensive participants of the Gubbio Study. METHOD: Echocardiographic LVM was determined in 91 nondiabetic, nonhypertensive individuals aged 45-54 years, participating in a population-based screening. LVM normalized for height2.7 was used in the analyses; LV hypertrophy was defined as a value of > or = 50 g/m2.7 in men or > or = 47 g/m2.7 in women. Fasting plasma insulin and glucose were measured and the Homeostasis Model Assessment (HOMA) index was used as a measure of insulin resistance. RESULTS: LVM was positively and significantly correlated with body mass index (BMI) (P < 0.01), waist circumference (P < 0.01) and HOMA index (P < 0.05), whereas correlations with plasma glucose and triglycerides did not reach statistical significance (P = 0.07 for both); all correlations were offset after adjusting for BMI. Fasting plasma insulin and HOMA index were not significantly different in subjects with or without LV hypertrophy (70.8 +/- 27.8 vs. 77.7 +/- 29.6 pmol/l and 2.2 +/- 1.0 vs. 2.6 +/- 1.4, respectively). Bivariate analysis performed stratifying participants above or below the 75th percentile of the sex-specific distribution for BMI (29.1 and 29.4 kg/m2 for males and females, respectively) and plasma insulin (84 pmol/l for either gender), did not result in appreciable differences in LVM due to insulin levels. Similar results were obtained replacing the HOMA index for insulin in the analysis. CONCLUSION: In nonhypertensive individuals left ventricular mass is not associated with plasma insulin independently of body mass index.     

Large periampullary villous tumor of the duodenum

A 67-year-old woman, who had symptoms of epigastric pain and abdominal distension, was found, on endoscopy, to have a large sessile villous adenoma of the periampullary duodenum. Despite the lack of evidence of malignancy, a pancreaticoduodenectomy procedure was performed, mainly because of the tumor size and site, involving the ampulla of Vater. The presence of the carcinoma was diagnosed only in the resected specimen by definitive histology. Because there is no general consensus on the optimal surgical procedure for the treatment of villous tumors of the duodenum, especially for the early stages, the indications for the operative procedure are discussed, based on a review of the literature.     

Transcatheter arterial chemoembolization (TACE) in treatment of hepatocellular carcinoma

BACKGROUND/AIMS: Substantial differences about the efficacy of transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma are reported in literature. This probably depends on the fact that in each single study, different patient selection criteria, type of epidemiological approach, end points adopted and kind of technical approach were used. This study aims to evaluate the efficacy of segmental transcatheter arterial chemoembolization in amelioring patient survival and to determine which patients might really benefit from this treatment. METHODOLOGY: To achieve our goals 193 consecutive patients (110 treated and 83 untreated) were studied. They were selected in the same period of time and matched as far as their demographic and clinical characteristics. RESULTS: Our results demonstrate that both in treated and control patients, Child class, alpha-fetoprotein and tumor diameter significantly influenced survival, resulting important prognostic factors. Transcatheter arterial chemoembolization significantly ameliorated survival in treated patients compared to controls (p < 0.0001). CONCLUSIONS: Transcatheter arterial chemoembolization significantly ameliorates survival in patients with hepatocellular carcinoma. However, the presence of large tumors producing high alpha-fetoprotein levels in patients with advanced Child class should discourage treatment.
