Annual report of the National Influenza Surveillance Scheme, 2004.

The National Influenza Surveillance Scheme includes data on influenza-like illness from sentinel general practitioner practices, laboratory reports of influenza from National Notifiable Diseases Surveillance Scheme and absenteeism data from a national employer. In 2004, 2,116 cases of laboratory-confirmed influenza-like illness were reported, which was 41 per cent lower than the previous year. Peak activity was recorded in September, a month later than in 2003. Influenza A was again predominant while influenza B had an increased activity compared to the previous season. Four hundred and fifty-four isolates were antigenically analysed: 342 were A (H3N2 strain), 4 were A(H1N1 strain) strains and 108 were influenza B viruses. Further antigenic drift was seen in the A(H3N2) subtype with approximately one third of all isolates antigenically distinguishable from the A/Fujian/411/2002 reference strain. Vaccination coverage indicated that 79 per cent of Australians aged over 65 years received the 2004 influenza vaccine.

Tuberculosis notifications in Australia, 2003.

The National Notifiable Disease Surveillance System (NNDSS) received 982 tuberculosis (TB) notifications in 2003, of which 947 were new cases, 33 were relapses and two were cases with unknown history. The incidence of TB in Australia has remained at a stable rate since 1985 and was 4.9 cases per 100,000 population in 2003. The high-incidence groups remain people born overseas and Indigenous Australians at 19.9 and 8.7 cases per 100,000 population, respectively. By contrast the incidence in non-Indigenous Australians was 0.9 per 100,000. Comparison of the 2003 TB notification data against the performance indicators set by National Tuberculosis Advisory Committee highlights that enhanced TB control measures should be considered among these high-risk groups.

Is colposcopy warranted in women with external anogenital warts?

OBJECTIVES.: To determine the prevalence of cervical dysplasia, diagnosed cytologically (squamous intraepithelial lesion [SIL]) or histologically (cervical intraepithelial neoplasia [CIN]), in women with external anogenital warts, and to determine the discriminating risk factors between those with and without cervical dysplasia. MATERIALS AND METHODS.: Chart review of women referred to colposcopy for external anogenital warts from 1990 to 1999. Human papillomavirus risk factors predictive for cervical dysplasia were assessed by logistic and Cox regression models. RESULTS.: There were 496 patients in this study. The prevalence of SIL by cytology was 20%: 18% low-grade squamous intraepithelial lesion and 2% high-grade squamous intraepithelial lesion. The combination of Pap smear and colposcopically directed biopsy identified dysplasia (SIL or CIN) in 30%, 4% of which were high-risk lesions (high-grade squamous intraepithelial lesion or CIN 2,3). Colposcopy performed much better than the Pap test alone in detecting CIN 2,3 lesions; 16 of 18 cases of CIN 2,3 diagnosed on biopsy had Pap smear results of low-grade squamous intraepithelial lesion or less, 7 of which were normal. Two thirds of those diagnosed with CIN 2,3 were aged 25 years and older. No differences in human papillomavirus infection risk factors were found between women with and without cervical dysplasia. CONCLUSIONS.: The high prevalence of CIN 2,3 in women with external anogenital warts warrants evaluation with colposcopy, particularly in women aged 25 years and older.
