Tobacco and Intra Ocular Pressure |
Abstract:
Glaucoma is an optic nerve disorder caused by raised intraocular
pressure. Among many drugs and agents causing glaucoma, tobacco has been
found to be one of the important agents. It is important for the clinical
practitioners as well as the general population to be aware of the ill
effects of tobacco on ocular circulation and intra ocular pressure.
Key words: Tobacco; intra ocular pressure; glaucoma |

Iyamu, Edgar Ekure, Eki Oghre. The Effect of Smokeless Tobacco on Intra-Ocular Pressure in a
Nigerian Population. |
Abstract:
The study was
conducted to find out the effect of smokeless tobacco (ST) on the intraocular pressure
(IOP) among non-smokers and smokers. Thirty-seven healthy volunteers of between 19–30
years age, classified into two groups, non-smokers (n=22) and- smokers (n=15), were used.
The IOPs of the right eyes were measured before (0min) and 1, 3 and 5mins after sniffing
40mg ST with Pulsair 2000 tonometer. Among non-smokers and smokers, the difference in mean
IOP at different times (0min, 1min, 3mins and 5mins) was statistically significant by
one-way ANOVA (p<0.05). Post hoc analysis using Duncan multiple range (DMR) test
showed that the peak IOP was at 1min after sniffing ST. The difference in IOP before
sniffing ST between smokers and non-smokers was statistically significant by Mann-Whitney
test (p<0.05). Also the difference in the peak time of 1min between smokers and
non-smokers was statistically significant (p<0.05). It was concluded that ST stimulates
aqueous humour formation thereby tending to raise IOP and this could enhance the chances
of developing ocular hypertension in patients that are predisposed to glaucoma.
Key words: Smokeless Tobacco, Intra Ocular Pressure |

Study on waste from hospital and clinics in Phitsanulok. |
Abstract:
Waste generation depends on numerous
factors such as established waste management methods, type of hospital establishment,
hospital specialization, proportion of reusable items employed in hospital, and proportion
of patients treated on a day-care basis. This study surveyed the waste from hospital and
clinics in Phitsanulok and found the average daily waste generated as general, medical and
hazardous waste from all hospitals in Phitsanulok Province at 1.751, 0.284 and 0.013
kg/bed respectively and at 0.323, 0.041 and 0.002 kg/bed respectively from all clinics in
Phitsanulok Province. Medical waste from all hospitals consisted of needles, gloves, drain
tubes, cottons and gauze, napkins, plastic syringes, swap and body parts with total daily
generation at 0.452, 0.480, 0.390, 0.404, 0.018, 0.355, 0.004 and 0.382 kg/bed
respectively. Information about proper waste management process is needed to improve
hospital waste management. Hospital waste management is an important and necessary
component of environmental health protection.

Ananth N. Laboratory Generated Artifacts in
Plasma Amino acid Quantitation |
Abstract:
The pace of physicians’
involvement in amino acid metabolism has been enormous in the last five decades. With
further development of technology to identify and quantitate upto picomoles of amino
acids, their metabolites and related peptides, diagnosis and effective medical
intervention in cases of inherited metabolic disorders have been well within the reach of
the clinician. Automatic amino acid analyzers have become an essential part of major
medical and research centers around the world. The technology has come indeed as a boon to
physicians who in particular deal with inherited defects of amino acid metabolism.
However, the technology comes with the risk of major deviations from the actual results
when a few minor variations are not looked into. Trivial variations in basic steps of
obtaining the sample, the choice of anticoagulant, hemolysis etc. can cause significant
variations in the resulting values, particularly while dealing with inherited defects of
amino acid metabolism and their treatment/management. Effects of such factors are
revisited here for the benefit of the modern day laboratory personnel.
Key words: Amino acid quantitation; artifacts; inherited metabolic disorders |
