Characteristics of speech following cervical spinal cord injury

The present study examined 24 individuals with either complete or incomplete injuries to the cervical spinal cord through the use of standardized assessments of dysarthria and a perceptual rating scale. Perceptual assessment revealed predominantly prosodic and phonatory disturbances, while physical impairments were common in the respiratory and laryngeal subsystems of speech production. A reduction in intelligibility and speaking rate resulted in a diminished communicative effectiveness ratio for most participants. Individuals showed a high degree of variation, with no clear relationship between lesion type and impairments present. Further investigation is required to verify the physiological nature of the respiratory and laryngeal impairments found in the present investigation and to determine the relative contributions of these to the overall presentation of speech and voice post cervical spinal cord injury (CSI).

Serologic response to human papillomavirus 16 among Australian women with high-grade cervical intraepithelial neoplasia

This study evaluated the detection of human papillomavirus (HPV) 16 antibody in HPV 16-associated cervical intraepithelial neoplasia (CIN) in Australian women. Seroreactivity to HPV 16 L1 virus-like particles was assessed in patients with CIN 2 (n = 169) and CIN 3 (n = 229) lesions previously tested for the presence of HPV DNA. Seropositivity was significantly commoner in women with HPV 16 DNA-positive lesions (98/184) than in women with no HPV DNA in the lesion (15/47) or with HPV of types other than 16 in the lesion (43/167) (P = 0.0004). In addition, seropositivity was observed in 33% (55/169) of women with CIN 2 and 46% (106/229) of women with CIN 3, in keeping with the lower fraction of CIN 2 (57/169) than CIN 3 (127/229) biopsies positive for HPV 16 DNA. HPV 16 seropositivity is most common in women with HPV 16-associated CIN, but many patients with HPV-associated CIN 3 are seronegative, and HPV 16 seropositivity is common in women with CIN associated with other HPV types. Overall, HPV 16 serology is a poor predictor of presence of HPV 16-associated CIN 3 in patient population studied.
