Introduction: Esophagus injuries secondary to caustic ingestion occurs frequently in children. Oral damages cannot give us a clear image of what has happened in upper GI. Therefore endoscopy is only diagnostic way to evaluate upper GI injuries. In this study, we found out the endoscopic results in children admitted with caustic ingestion in Qaem(A. S.) hospital between 2011 to 2013 , and comp...

The rate of decomposition of hydrogen peroxide has been measured in aqueous, concentrated (0.1–1M) reagent-grade sodium carbonate liquors and compared with that in sodium hydroxide liquors at the same pH, temperature, and ionic strength. Over the ranges of temperature (303–323 K), pH (10.0–10.6), and ionic strength (1.5–3.0M), and without peroxide-stabilizing additives, hydrogen peroxide decomp...

Objective To evaluate factors associated with rising trends of intentional ingestion caustic agents for suicidal attempts in Pakistan. Study Design: Cross Sectional, Observational study. Setting: Tertiary Health Care Center Islamabad. Period: January 2019 to December 2020. Material & Methods: One hundred subjects treated Gastroenterology unit were interviewed on a written questioner after t...

The secant caustic of a planar curve M is the image singular set map . We analyze geometrical properties curve, i.e. number branches caustic, parity cusps and inflexion points in each branch this set. In particular, we investigate detail some rosette, smooth regular oriented closed with non-vanishing curvature.

It is shown that the caustic formed by the reflection of a plane wave off the inside of a cylinder is independent of the angle of incidence of the wave with the axis of the cylinder. Moreover, the caustic formed by the reflection of a point source off a cylinder is proven to be translation symmetric. This is done by constructing explicitly the focal sets of the reflected line congruences (2-par...

Bleach solutions containing the active ingredient hypochlorite (OCl-) serve as powerful biological disinfectants but are highly caustic and present a significant compatibility issue when applied to contaminated equipment or terrain. A neutral, bicarbonate-buffered aqueous solution of Oxone (2K2HSO5.KHSO4.K2SO4) and sodium chloride that rapidly generates hypochlorite and hypochlorous acid (HOCl)...
