Background: Gonorrhea since the ancient times is causing significant morbidity. Though a number of methods are
available for diagnosis in men, culture still remains the gold standard. Gonococci are delicate and fastidious bacteria
but its remarkable ability to develop resistance to a variety of antibiotics makes it a major threat to public health. Objectives: To detect the incidence in symptomatic men and in vitro antimicrobial susceptibility pattern of the
gonococcal isolates. Materials & Methods: - 100 urethral swabs from men with urethritis were screened for presence of gonococci by
gram stain and culture on Chocolate Agar and Modified Thayer-Martin medium. The isolated gonococci were screened for Penicillinase production and susceptibility to antibiotics was subsequently carried out by standard disc diffusion method. Results: - Gonorrhoea was detected in 56 of the urethral swabs giving a incidence of 56%. The difference of
detection in gram stain and culture was insignificant (P>0.05). Of all the isolated gonococci considerable resistance was seen to ciprofloxacin(46.4%), tetracycline(23.2%) and Penicillin(17%) with Incidence of PPNG being 12.5%. All strains were uniformly sensitive to Spectinomycin and Cephalosporins. Conclusions: - Neisseria gonorrhoeae is main etiological agent in urethritis in sexually active men and culture
though time consuming, costly and demands expertise is still better method for diagnosis as gives high isolation rate and observe changing patterns in antibiotic susceptibility to commonly used antimicrobials. Keywords: Gonorrhoea, Men, Antibiotic susceptibility
culture was regarded as difficult and uncertain, but many decades ago the problems were overcome, and Gonorrhea is one of the oldest known bacterial diseases culture became the method of first choice for diagnosis, that was recognized as sexually transmitted infection by and remains the "gold standard" against which other 13th century but still causes significant morbidity among methods are measured. However, culture is by no means sexually active individuals1. Global estimates of disease the only method available for diagnosis of are difficult to obtain but WHO suggests that gonorrhoea.3,4,5. worldwide, 62 million new cases occur annually. The greatest burden of disease falls upon less developed Alternative methods have been evaluated exclusively for countries so the highest incidence and prevalence is the detection of gonococci in clinical specimen such as found in Africa and South-East asia. In India, the ELISA, immunofluorescence, DNA probes, genetic prevalence rate of gonorrhea is 3-19%2. Gonorrhoea transformation, polymerase chain reaction (PCR). caused by Neisseria gonorrhoeae, is diagnosed Though rapid, sensitive and specific, PCR has several presumptively by the presence of intracellular and limitations; it needs costly equipment and reagents, extracellular Gram negative cocci on a Gram stain. experienced technician, and the organism cannot be Culture for the causative organism is considered isolated in this method for further investigation.5,6 On necessary, however, as it dies rapidly if exposed to the other hand, culture, though more time consuming, desiccating or oxidising conditions, so isolation of needs to maintain viable organism till culture is done gonococci requires good specimen collection and and having less sensitivity in some samples, is the bedside inoculation or suitable transport, a moist carbon method of choice for identification of gonococci, dioxide enriched atmosphere and enriched and or particularly in developing countries because is cost selective medium3,4,5.

As for choice of culture media whether positivity of smear in diagnosis of gonorrhea is not enriched (CA) or selective (MTM), we recommend statistically significant (P>0.05) (Table 2). Similar results both, because MTM have higher isolation rate but some were reported by Sherrard et al8 94% positivity of smear strains of gonococci are sensitive to Vancomycin and in symptomatic men. These results further confirm that are inhibited on MTM are isolated only on CA. Due to Microscopy of a gram-stained urethral sample is a highly high prevalence PPNG and resistance in gonococci to sensitive examination in diagnosis of gonorrhoea when Penicillin, Ciprofloxacin and Tetracycline it is compared to culture in symptomatic men, although its mandatory to perform antibiotic sensitivity testing and sensitivity is much reduced in asymptomatic men, even observe the changing pattern in antibiotic susceptibility when most of these are presenting as known contacts of pattern.

Jae-Min Jung and Ho-Yeon Kim: Third-person Effects in the Stock Market:Perception of Experts & Non-experts and Impacts on Attitude Third-person Effects in the Stock Market: Perception of Experts & Non-experts and Impacts on Attitude Jae-Min Jung* and Ho-Yeon Kim** Abstract: The third-person effect was tested by examining whether people perceive a greater influence of unidentified information recommending stocks in the Internet on others than on themselves. Findings confirm the third-person effect but also show subjects with stock market experience perceive a greater influence on others than did subjects with no stock market experience. Additionally, subjects demonstrated a larger third-person effect when "others" are specified as novice investors who have little knowledge or experience in stock trading than when "others" are identified as experienced traders. After controlling for SES and interest and experience in stock trading, the third-person perception remained.

Autism is treatable: hope that is real, treatments that heal. Townsend Letter for Doctors and Patients; 10/1/2004; Reagan, Lisa "My name is Michael Augerson. I'm autistic. Basically when you're autistic, you feel urges to do things that you really need to do. You can't stop yourself. Like you have taken a drug. You have no idea what others are talking about, because it doesn't make any sense to you. Others think of you as a freak, loon, or a retard.
