Outcome of three consecutive inadequate cervical smears.

A retrospective audit of women with three consecutive inadequate cervical smears during 1998-99 was conducted at Birmingham Heartlands Hospital. The commonest reasons were obscured by polymorphs (34.5%) and sparse cellularity (28.9%). Seventy-three per cent (73%) were followed up at colposcopy and 22.1% had histological assessment; 15.9% of women had an abnormality detected, 10.6% with abnormal histology and 5.3% with a cytological abnormality only. Cytological abnormalities were seen in 11.1% of the screening population. This study did not identify a cytological criterion to differentiate those that would or would not have an abnormality on follow-up. It is suggested that all women with three consecutive inadequate smears should have adequate follow-up, although this may place increased demands on colposcopy services.

Changes in stimulation levels over time in nucleus 22 cochlear implant users.

The purpose of this study was to evaluate changes that occur over time in the electrical stimulation levels of cochlear implant users. A retrospective review of program summaries for 26 postlingually deafened adult Nucleus cochlear implant users was completed. Program summaries were used to assess changes in electrical stimulation at threshold (T) and maximum comfort (C) levels. Comparisons were made at intervals including the subject's initial stimulation and 2-week, 3-month, 6-month, 1-year, and most recent programming sessions. Five patients had 5 years or more of implant use; 8 patients had 3 to 5 years or more of implant use; and the remainder had been using their implant for 2 to 3 years. No patient with less than 2 years of implant use was included. Results indicated that changes in stimulation levels occur gradually over time. Although the changes in stimulation levels from one programming session to the next were not significant, the changes in current requirements for both T and C levels were found to be significant when we compared the 6-month and most recent programming intervals.

Speech perception results in children with cochlear implants: contributing factors.

Speech perception test results were obtained from a group of 40 pediatric cochlear implant users. Half of the children participated in oral-only habilitation programs, which included both traditional oral and auditory-verbal approaches, and half participated in programs that used a combination of oral and manual communication referred to as total communication (TC). Analysis of the scores showed that children enrolled in oral-only habilitation programs scored significantly higher on the speech perception measures than did children who were enrolled in total communication based programs. These results were inconsistent with those of other reports, which suggested that communication methods had little effect on implant outcomes. To further examine the reasons for the differences in performance, we analyzed 7 additional factors, including length of implant use, age at surgery, device type, socioeconomic status, bilingualism, school setting, and participation in private therapy, which may affect implant performance. Multiple-regression analysis again showed communication mode to be the factor most highly correlated with speech perception abilities among this group of children.
