Young-onset dementia, defined as dementia occurring under the age of 65, is an increasingly recognized
cause of morbidity and disability. There are few reports of the clinical profile of young-onset dementia
from India. The objective of this study was to determine the clinical profile of patients attending a
specialist cognitive disorders clinic in West Bengal, an eastern state of India. Almost one-fourth (94/379,
24.5%) of all the patients with dementia were of young onset. Women constituted about one-third of
these cases. There was a gradual increase in the number of cases with rising age. The most common
etiologies were Alzheimer disease (33%), frontotemporal dementia (27%), and vascular dementia
(20%). In contrast to other published studies of young-onset dementia, frontotemporal dementia
was commoner than vascular dementia. This could be due to referral bias. A positive family history
was found in close to one-fifth of the patients. Close to 10% of the patients had reversible causes of
dementia. Community based study is required to confirm the findings of this study.

OBJECTIVETo analyze the learning curve of gastric bypass procedure on rats model by a single operator.
METHODSFrom June 2013 to September 2013, two groups (group A and group B) of rats model were performed gastric bypass surgery, 60 rats for each group. Each group was divided into 3 stages according to sequence. The operative time and postoperative survival rate were compared between A group and B group at first, then among stages of each group.
RESULTSThere were no significant differences between A and B group in operative time and postoperative survival rate. However, the operative time significantly decreased in group AII( and AIII( compared with AI(, [(78.5±2.5) and (73.3±1.4) with (127.3±3.2) min, P<0.01]. The postoperative survival rate was increased in group AII( and AIII( than in the group AI(, [75%(15/20) and 85%(17/20) with 30%(6/20), P<0.05]. All results of 3 stages in group B was similar to group A.
CONCLUSIONFor an efficient and stable rate of successful model establishment, the researcher needs to operate about 20 rats to pass the learning curve of gastric bypass procedure.

PURPOSE: Based in a hospital serving one of the most deprived areas in the United Kingdom (UK), we aimed to investigate, using the Indices of Deprivation 2010, the hypothesis that deprivation affects the stage and mode of presentation of colorectal cancer. METHODS: All newly diagnosed patients with colorectal cancer presenting to a District General Hospital in the UK between January 2010 and December 2014 were included. Data were collected from the Somerset National Cancer Database. The effect of social deprivation, measured using the Index of Multiple Deprivation Score, on the stage and mode of presentation was evaluated utilizing Microsoft Excel and IBM SPSS ver. 22.0. RESULTS: A total of 701 patients (54.5% male; mean age, 76 years) were included; 534 (76.2%) underwent a surgical procedure, and 497 (70.9%) underwent a colorectal resection. Of the patients undergoing a colorectal resection, 86 (17.3%) had an emergency surgical resection. Social deprivation was associated with Duke staging (P = 0.09). The 90-day mortality in patients undergoing emergency surgery was 12.8% compared to 6.8% in patients undergoing elective surgery (P = 0.06). No association was found between deprivation and emergency presentation (P = 0.97). A logistic regression analysis showed no increase in the probability of metastasis amongst deprived patients. CONCLUSION: This study suggests an association between deprivation and the stage of presentation of colorectal cancer. Patients undergoing emergency surgery tend to have a higher 90-day mortality rate, although this was not related to deprivation. This study highlights the need to develop an individual measure to assess social deprivation.

Carcinoembryonic antigen (CEA) is not normally produced in significant quantities after birth but is elevated in colorectal cancer. The aim of this review was to define the current role of CEA and how best to investigate patients with elevated CEA levels. A systematic review of CEA was performed, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were identified from PubMed, Cochrane library, and controlled trials registers. We identified 2,712 papers of which 34 were relevant. Analysis of these papers found higher preoperative CEA levels were associated with advanced or metastatic disease and thus poorer prognosis. Postoperatively, failure of CEA to return to normal was found to be indicative of residual or recurrent disease. However, measurement of CEA levels alone was not sufficient to improve survival rates. Two algorithms are proposed to guide investigation of patients with elevated CEA: one for patients with elevated CEA after CRC resection, and another for patients with de novo elevated CEA. CEA measurement has an important role in the investigation, management and follow-up of patients with colorectal cancer.

Purpose:
Malignant large bowel obstruction is a surgical emergency that requires urgent decompression. Stents are increasingly being used, though reported outcomes are variable. We describe our multidisciplinary experience in using stents to manage malignant large bowel obstruction.
Methods:
All patients undergoing colorectal stent insertion for acute large bowel obstruction in a teaching hospital were included. Outcomes, complications, and length of stay (LOS) were recorded.
Results:
Over a 7-year period, 73 procedures were performed on 67 patients (37 male, mean age of 76 years). Interventional radiology was involved in all cases. Endoscopic guidance was required in 24 cases (32.9%). In 18 patients (26.9%), treatment intent was to bridge to elective surgery; 16 had successful stent placement; all had subsequent curative resection (laparoscopic resection, 8 of 18; primary anastomosis, 14 of 18). Overall LOS, including both index admission and elective admission, was 16.4 days. Treatment intent was palliative in 49 patients (73.1%). In this group, stents were successfully placed in 41 of 49 (83.7%). Complication rate within 30 days was 20%, including perforation (2 patients), per rectal bleeding (2), stent migration (1), and stent passage (5). Nineteen patients (38.8%) required subsequent stoma formation (6, during same admission; 13, during subsequent admission). Overall LOS was 16.9 days.
Conclusion
In our experience colorectal stents can be used effectively to manage malignant large bowel obstruction, with only selective endoscopic input. As a bridge to surgery, most patients can avoid emergency surgery and have a primary anastomosis. In the palliative setting, the complication rate is acceptable and two-thirds avoid a permanent stoma.
