Invited Speakers : Abstracts & Introduction
Abstract:
Non-woven medical disposable products have been well
established over the past many years in providing advanced
infection control and combating critical medical
infections such as MRSA, HIV, CJD and Hepatitis B as it
provides the highest levels of liquid and microbial
protection to both patients and operation theatre staff.
Many research studies in infection control also continues
to praise the benefits of single use products as each item
is only used in one procedure and it offers the important
advantages over re-usable products like no contagious
agents left by previous patient / environment, no wear and
tear due to numerous laundering cycles, no compulsory
rigorous re-testing before every re-use and no complex
division of responsibility boundaries between supplier and
end user.
Apart from this there are also certain
misconceptions about disposal of single use non-woven
products. Advanced technologies like Plasma Pyrolysis can
help for disposal of medical waste. It integrates the
thermo-chemical properties of plasma with the pyrolysis
process. The intense and versatile heat generation
capabilities of plasma pyrolysis technology enables it to
dispose of all types of medical waste including plastics
waste, biomedical waste and hazardous waste in a safe and
reliable manner.

Abstract:
A polyurethane stent is a narrow and hollow plastic tube
that runs inside the ureter between the kidney and urinary
bladder. These stents find wide application in treatment
of patients with urological disorder where there is any
obstruction to flow of the urine. Majority of patients
(about 50%) with such stents are at a risk of urinary
tract infection. Encrustation upon implanted ureteric
stent and the ensuing complications lead to morbidity. The
present study is aimed at understanding the kinetics of in
vitro encrustation of Calcium oxalate the predominant
salt, in the presence of various other salts (sodium
hydrogen phosphate, magnesium sulphate hepta hydrate,
ammonium chloride and mixture of ammonium chloride-
magnesium sulphate hepta hydrate) and E.coli, a
uropathogens. Calcium oxalate is formed by the combination
calcium chloride and di-sodium oxalate. In the absence of
E. Coli sodium ions favours Ca adsorption whereas
magnesium ions greatly depress it. Presence of ammonia
favours Ca adhesion by increasing the alkalinity of the
solution. The stent surface becomes more hydrophilic upon
salt deposition. In the presence of E.Coli, Mg ions
enhance the encrustation of Calcium oxalate, whereas other
salts decrease its deposition. This necessitates newer
strategies to design stents that are more inert and resist
encrustation and biofilm formation.
