BACKGROUND: Human papillomavirus is a well-established cause of the development of a variety of epithelial lesions in the cervix. However, as yet, incorporation of HPV testing into cervical cancer screening either as an adjunct or stand alone test is limited due to its cost. We therefore here ascertained the presence and type specificity of human papilloma virus (HPV) DNA in routine cervical scrapings.
MATERIALS AND METHODS: Cervical scrapings were collected from women attending clinics for routine Pap smear screening. HPV-DNA was detected by PCR using MY09/11 and GP5+/GP6+ primer sets and genotyping was accomplished by cycle-sequencing.
RESULTS: A total of 635 women were recruited into the study with mean ± SD age of 43 ± 10.5 years. Of these 92.6% (588/635) were reported as within normal limits (WNL) on cytology. The presence of HPV infection detected by nested MY/GP+-PCR was 4.4% (28/635). The overall prevalence of high-risk HPV (HR-HPV) in abnormal Pap smears was 53.8% (7/13). HPVs were also seen in 3.1% (18/588) of smears reported as WNL by cytology and 5.9% (2/34) in smears unsatisfactory for evaluation.
CONCLUSIONS: The overall percentage of HPV positivity in routine cervical screening samples is comparable with abnormal findings in cytology. Conventional Pap smear 'missed' a few samples. Since HPV testing is expensive, our results may provide valuable information for strategising implementation of effective cervical cancer screening in a country with limited resources like Malaysia. If Pap smear coverage could be improved, HPV testing could be used as an adjunct method on cases with ambiguous diagnoses.

Objective: Assess and analyse the awareness, knowledge, and attitudes of university students regarding HPV and its vaccine. Methods: A cross-sectional study was designed with questionnaire serving as the research instrument. A total of 425 university students were recruited voluntarily. Thirteen assessable questions were analysed to reveal the mean total knowledge score of HPV and its vaccine. Both descriptive and statistical approach were employed to analyse the research outcomes. Results: Students were moderately aware as 59.8% and 49.6% have heard about HPV and its vaccine, respectively. The mean total knowledge score was 5.26 ± 3.10 out of 13 which was found to be moderately knowledgeable. Female (N= 235) have a significantly higher mean knowledge score in comparison to male (N= 190) at 5.58 ± 2.80 versus 4.87 ± 3.40, respectively (p<0.05), likely due to the disease profiles favouring female. As hypothesised, health-related school students (N= 171) outperformed other schools (N= 254) at 7.00 ± 2.95 versus 4.10 ± 2.62, respectively (p<0.001). In general, the score depends on participant’s gender and educational background (χ2= 25.426, p<0.01 and χ2= 105.337, p<0.001, respectively). Despite low vaccination uptakes (28.5%), students accept the vaccine following physician’s recommendation and reject due to its cost. A positive attitude was seen as majority (88.7%) wished to know more about HPV. Conclusion: Moderation in awareness, knowledge and attitudes reflect the lifestyle of an urbanised population where information is accessible. Healthcare professionals, media campaign, and educational talk refinement are therefore essential in controlling the disease by spreading awareness.
