Changing patterns of Vibrio cholerae in sevagram between 1990 and 2005
Purpose: A retrospective analysis was done to note changes in
prevalence, distribution of biotypes, serotypes, antibiotic
susceptibility patterns and phage types of Vibrio cholerae isolated
in Mahatma Gandhi Institute of Medical Sciences, Sevagram over a period
of 16 years. Methods: A total of 535 strains of V. cholerae were
isolated from 10,406 stool samples and rectal swabs from January 1990
to December 2005. These comprised of serogroups O1 - 427 (79.89%), O139
- 86 (16.07%) and non O1, non O139 - 22 (4.11%). No classical V.
cholerae was isolated. Results: Vibrio cholerae serogroup O1 serotype
Ogawa was the predominant isolate till 1992. During 1993, serogroup
O139 became the main isolate; however, it completely disappeared during
1995-1996 only to reappear in 1997. Serotype Inaba in our area was
conspicuous by its absence with only two strains being isolated till
June 1999, but during July-December 1999, 11 out of 15 V. cholerae O1
isolates were El Tor Inaba. T4 was the predominant phage type till
1990, T2 during 1991-1994 and T27 (as per the new scheme) thereafter.
Resistance to tetracycline varied between 2 and 17% for V. cholerae
O1. Conclusions: The paper reports on the changing epidemiological
markers of V. cholerae isolated from a rural hospital over a period of
16 years

An Overall Aspect of Electroless Ni-P DepositionsâA Review Article
Literature on electroless Ni-P deposition, in recent decades, has dwelled primarily on surface
engineering and corrosion-resistant applications. By contrast, we have many research articles devoted
to the engineering aspects of the electroless Ni-P depositions and their technology. The present article
deals with the development of electroless Ni-P bath, advantages and mechanisms of deposition, and
applications of the Ni-P deposits. We also present a comparison of the properties of electroless Ni-P
and Ni-B as well as the recent developments in nickel-phosphorous research. We attempt to review
these in a detailed manner. We also briefly discuss the future developments of electroless Ni-P

Predictors for anastomotic leak, postoperative complications, and mortality after right colectomy for cancer: Results from an international snapshot audit
Background: A right hemicolectomy is among the most commonly performed operations for colon cancer, but modern high-quality, multination data addressing the morbidity and mortality rates are lacking. Objective: This study reports the morbidity and mortality rates for right-sided colon cancer and identifies predictors for unfavorable short-term outcome after right hemicolectomy. Design: This was a snapshot observational prospective study. Setting: The study was conducted as a multicenter international study. Patients: The 2015 European Society of Coloproctology snapshot study was a prospective multicenter international series that included all patients undergoing elective or emergency right hemicolectomy or ileocecal resection over a 2-month period in early 2015. This is a subanalysis of the colon cancer cohort of patients. Main Outcome Measures: Predictors for anastomotic leak and 30-day postoperative morbidity and mortality were assessed using multivariable mixed-effect logistic regression models after variables selection with the Lasso method. Results: Of the 2515 included patients, an anastomosis was performed in 97.2% (n = 2444), handsewn in 38.5% (n = 940) and stapled in 61.5% (n = 1504) cases. The overall anastomotic leak rate was 7.4% (180/2444), 30-day morbidity was 38.0% (n = 956), and mortality was 2.6% (n = 66). Patients with anastomotic leak had a significantly increased mortality rate (10.6% vs 1.6% no-leak patients; p 65 0.001). At multivariable analysis the following variables were associated with anastomotic leak: longer duration of surgery (OR = 1.007 per min; p = 0.0037), open approach (OR = 1.9; p = 0.0037), and stapled anastomosis (OR = 1.5; p = 0.041). Limitations: This is an observational study, and therefore selection bias could be present. For this reason, a multivariable logistic regression model was performed, trying to correct possible confounding factors. Conclusions: Anastomotic leak after oncologic right hemicolectomy is a frequent complication, and it is associated with increased mortality. The key contributing surgical factors for anastomotic leak were anastomotic technique, surgical approach, and duration of surgery
