Does Body Mass Index Reduction by Bariatric Surgery Affect Laryngoscopy Difficulty During Subsequent Anesthesia?

Background: The effect of body mass index (BMI) reduction following bariatric surgery on subsequent airway management has not been investigated. This study aimed to investigate the association between BMI reduction and airway assessment and management measured by Mallampati class (MC) and laryngoscopy grade (LG).

Methods: We conducted a retrospective study over 6 years to compare the BMI changes, MC and LG in patients having weight reduction bariatric surgery followed by subsequent surgery.

Effects of nanocrystalline silver (NPI 32101) in a rat model of ulcerative colitis.

Nanocrystalline silver (NPI 32101) has been demonstrated to have antimicrobial and anti-inflammatory properties. The purpose of this study was to assess the effect of NPI 32101 in a rat model of ulcerative colitis and the possible mechanisms of action of the effects observed. NPI 32101, 4 mg/kg intracolonically or 40 mg/kg orally, significantly reduced colonic inflammation compared to the placebo and no-treatment groups.

The importance of blood sampling site for determination of hemoglobin and biochemistry values in major abdominal and orthopedic surgery.

Study Objective: To determine whether sampling of blood from different sites influences laboratory results.

Design: Prospective, double-blind study.

Setting: University-affiliated hospital in Israel.

Topical nanocrystalline silver cream suppresses inflammatory cytokines and induces apoptosis of inflammatory cells in a murine model of allergic contact dermatitis.

Background: Nanocrystalline silver has both antimicrobial and anti-inflammatory properties. However, the exact mechanisms underlying these activities are not known.

Objectives: The objectives of this study were to assess the anti-inflammatory effects of nanocrystalline silver using a murine model of allergic contact dermatitis, compare the effects with those of tacrolimus and a high potency steroid, and to relate the effects to modulation of pro-inflammatory cytokines and apoptosis of inflammatory cells.

Anti-inflammatory effect of topical nanocrystalline silver cream on allergic contact dermatitis in a guinea pig model.

The anti-inflammatory activity of topical nanocrystalline silver cream was assessed and compared with the effects of topical steroids and currently available immunosuppressants using a guinea pig model of allergic contact dermatitis. Dermatitis was induced with dinitrochlorobenzene and treated with different concentrations of nanocrystalline silver, medium and high potency steroids, tacrolimus and pimecrolimus, or appropriate vehicles once daily for 5 days. Erythema was evaluated daily (on a score of 0 to 4, from absent to very severe) and histopathology of the skin biopsies was evaluated after 5 days of treatment.
