Work assignments, delegation of tasks and job satisfaction among Danish dental hygienists.

INTRODUCTION: Recent legislation in Denmark has made it possible for dentists to delegate their tasks to dental hygienists. Previous studies have shown that Danish dental hygienists primarily were performing assignments within their own work field. These assignments include prophylaxis or instructing patients in oral health care. However, studies have also shown that Danish dental hygienists performed dental nurse assignments such as chair-side assistance, unit cleaning and disinfection of instruments. OBJECTIVES: The objectives of this study were to investigate (i) the range of work assignments performed by Danish dental hygienists, (ii) the types of dentist tasks performed by Danish dental hygienists and (iii) job satisfaction among Danish dental hygienists. DESIGN: Dental hygienists graduating in 2004-2007 were invited to participate in this study. METHODS: Participants answered an email-distributed questionnaire. The questionnaire consisted of questions regarding job satisfaction, assignments performed, postgraduate course attendance, receiving assistance from a dental nurse and which work assignments Danish dental hygienists wish to perform in the future. RESULTS: The results of this study showed that 90% of Danish dental hygienists were satisfied with their job and 52% were performing dentists' tasks. Among dentists' tasks performed by Danish dental hygienists, invasive caries therapy was the most frequently performed task. CONCLUSION: The type of assignments performed by Danish dental hygienists today appears to be changing compared to previous studies. From initially performing prophylaxis and chair-side assistance for the dentist, Danish dental hygienists today are performing a wider range of tasks which includes dentists' tasks.

Surgical resection versus watchful waiting in low-grade gliomas.

BACKGROUND: Infiltrating low-grade gliomas (LGG; WHO grade 2) typically present with seizures in young adults. LGGs grow continuously and usually transform to higher grade of malignancy, eventually causing progressive disability and premature death. The effect of up-front surgery has been controversial and the impact of molecular biology on the effect of surgery is unknown. We now present long-term results of upfront surgical resection compared with watchful waiting in light of recently established molecular markers. MATERIALS AND METHODS: Population-based parallel cohorts were followed from two Norwegian university hospitals with different surgical treatment strategies and defined geographical catchment regions. In region A watchful waiting was favored while early resection was favored in region B. Thus, the treatment strategy in individual patients depended on their residential address. The inclusion criteria were histopathological diagnosis of supratentorial LGG from 1998 through 2009 in patients 18 years or older. Follow-up ended 1 January 2016. Making regional comparisons, the primary end-point was overall survival. RESULTS: A total of 153 patients (66 from region A, 87 from region B) were included. Early resection was carried out in 19 (29%) patients in region A compared with 75 (86%) patients in region B. Overall survival was 5.8 years (95% CI 4.5-7.2) in region A compared with 14.4 years (95% CI 10.4-18.5) in region B (P < 0.01). The effect of surgical strategy remained after adjustment for molecular markers (P = 0.001). CONCLUSION: In parallel population-based cohorts of LGGs, early surgical resection resulted in a clinical relevant survival benefit. The effect on survival persisted after adjustment for molecular markers.

Cognitive and outcome measures seem suboptimal in children with cochlear implants - a cross-sectional study.

OBJECTIVE: This study investigates whether cognition as a single variable significantly influences the hearing and speech outcomes of children with cochlear implants (CIs). More specifically, it identifies various types of cognitive disorders among children with CI, comparing these children's cognitive abilities to the outcomes of CI in terms of hearing and speech performance. STUDY DESIGN: Cross-sectional cognitive testing of children with CIs. SETTING: West Danish CI Centre, Aarhus University Hospital, Denmark. MATERIALS AND METHODS: Fifty-eight CI children underwent postoperative cognitive evaluation. Cognitive tests included Bayley Scales of Infant Development (Bayley-III), Snijders-Oomen Nonverbal Intelligence Test Revised (SON-R) and Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV), depending on the age of the child. Outcome measures of hearing and speech capacity after CI consisted of Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR) and Peabody Picture Vocabulary Test-4 (PPVT-4). RESULTS: Only PPVT-4 correlated significantly with cognition scores. Over time, the value of CAP and SIR seems limited by a pronounced ceiling effect. CONCLUSION: The most widely used outcome tests after CI, that is CAP and SIR, may not reflect cognitive disabilities sufficiently due to pronounced ceiling effects. International guidelines suggesting a panel of robust age-matched tests are warranted to optimise rehabilitation programmes as well as the counselling of parents.

Long-term outcome of resective epilepsy surgery in Norwegian children.

AIM: The aim of this study was to evaluate the long-term results of resective surgery on children with difficult-to-treat epilepsy in Norway. METHODS: In the period 1995-2004, 64 surgical procedures (54 resections and 10 functional hemispherotomies) were performed in 54 children. The children's medical records were retrospectively reviewed at a minimum of 2 years after surgery. We sent a questionnaire regarding their epilepsy (seizures, usage of antiepileptic drugs) and general functioning (social situation, motor, language, cognition, behavioural or emotional problems, any remedial action) to the children/parents after a mean follow-up period of 7 years. RESULTS: 55.5% of the children were seizure-free. The success rate varied according to the type of surgery. Best results were found after functional hemispherotomies and temporal lobe resections, as nine of 10 (90%) and 10 of 19 (53%) of these patients, respectively, became seizure-free. In addition to a better seizure control, 71% of the children/parents reported of a better cognitive and psychosocial functioning. CONCLUSION: The results of epilepsy surgery in this paediatric cohort are very edifying, and it is our impression that this treatment option is underused in Norway.
