- Twenty-one males underwent an interview, clinical investigation, and measurement of urine flow and residual volume 15-25 years after surgery. Although surgical techniques have been improved during recent decades, the results of hypospadias repair made 20 years ago are nethertheless acceptable and most patients regard the outcome as satisfactory.

Growth of one-dimensional nanostructures in MOVPE

- The use of metal organic vapor-phase epitaxy (MOVPE) for growth of one-dimensional nanostructures in the material systems GaAs, GaP, InAs and InP is investigated. Some kinetic effects are discussed, especially the general finding that in MOVPE thinner whiskers grow faster than thicker whiskers. Effects of growth temperature on growth rate and shape of the whiskers, the effects of different growth directions on the perfection of the materials and the possibilities to grow heterostructures in axial and lateral directions are reported. Ways to overcome the randomness in whisker growth by controlled seeding of the Au particles and by using lithography for site control are demonstrated.

Why do parents hesitate to vaccinate their children against measles, mumps and rubella?
- 2004

Ingår i: Acta Paediatr. - 0803-5253. ; 93:9, s. 1232-7

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Thanks to a successful voluntary vaccination programme, measles, mumps and rubella are rare diseases in Sweden. Coverage among children 18 mo of age has been 99%, but the measles, mumps and rubella vaccination (MMR) has increasingly been questioned among parents. AIM: To study reasons why parents choose not to vaccinate their child against measles, mumps and rubella, and their opinions on vaccines and the diseases themselves. A secondary objective was to compare coverage at 18 mo of age based on parental report with the national statistics based on patient charts. METHODS: The official statistics were compared with patient charts for two birth cohorts in the city of Goteborg, Sweden. Out of these children born in 1995 and 1996, 300 unvaccinated and vaccinated children were identified. Their parents received a postal questionnaire assessing the parent's views on vaccines and childhood diseases. RESULTS: The documented vaccine coverage in this study was higher in 1995 and 1996 than official statistics indicated. The major reason, for both groups, for accepting respectively declining vaccination was strengthening the child's immune system. Parents with children unvaccinated against MMR were also more likely to have declined vaccination against diphtheria, polio, tetanus, Haemophilus influenzae and pertussis. One-third of the parents with a child unvaccinated against MMR had not yet made their final decision 3 y after the vaccine offer. Few parents, both with vaccinated and unvaccinated children, had acquired vaccine information from the Internet. Both groups believed that insufficient time was allocated for vaccine information and discussion at the Child Health Centre. CONCLUSION: Our study indicates that official statistics on MMR vaccination uptake underestimate the number of vaccinated children. Vaccine safety is a major concern for many parents and needs to be addressed by healthcare professionals at institutions offering paediatric vaccinations.

- An organic electronic paper display technology (see Figure and also inside front cover) is presented. The electrochromic display cell together with the addressing electrochemical transistor form simple smart pixels that are included in matrix displays, which are achieved on coated cellulose-based paper using printing techniques. The ion-electronic technology presented offers an opportunity to extend existing use of ordinary paper.

Adult skeletal profile in isolated cleft palate: a comparison of the von Langenbeck and Wardill procedures for primary repair of the palate
- 2001
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 35:4, s. 387-397

Tidskriftsartikel (refereegranskat)abstract
- Sixty-four adult patients operated on for isolated cleft palate were evaluated with regard to facial skeletal morphology using conventional radio-cephalometry. Dental occlusion was assessed clinically. Forty-two had had a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at 18 months. The mean error of the method was 0.7 degree for angular, and 0.9 mm for linear, measurements. The group with clefts had less maxillary prognathism (s-n-ss), more maxillary inclination (NSL/NL), more retroclined lower incisors (ILI/ML), and shorter total and upper facial heights (n-gn, n-sp) compared with the reference group. Multiple regression analysis was used to evaluate differences between the two treatment regimens. Explanatory variables in addition to surgical technique were sex, severity of cleft, and presence of a velopharyngeal flap. Only one variable, lower incisor inclination (ILI/ML), was different for the two regimens. Ten (24%) in the von Langenbeck group had a lateral cross-bite compared with one (5%) in the Wardill group. Other variables in a multivariate regression analysis were affected by sex and severity of cleft to various degrees. This study showed no obvious differences in facial skeletal morphology that could be attributed to surgical technique. Factors other than technique, including sex, age, and severity of cleft merit attention.

Von Langenbeck or Wardill procedures for primary palatal repair in patients with isolated cleft palate--speech results
- 2000
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 34:1, s. 27-32

Tidskriftsartikel (refereegranskat)abstract
- Sixty-six patients operated on for isolated cleft palate were evaluated as adults, and their speech was assessed clinically. Forty-four had undergone a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at the age of 18 months. Speech was judged subjectively by the patients themselves, and perceptual assessment was made by three speech pathologists. The remaining speech problems, mainly hypernasality, were moderate or severe in 7 (16%) of the patients in the von Langenbeck group, and in 7 (32%) in the Wardill group. On the other hand, the patients in the Wardill group had fewer fistulas closed, and fewer velopharyngoplasties. There were no significant differences between the two methods regarding speech in adulthood. The Wardill method produced significantly more scar tissue clinically, which carries the potential risk of inhibition of facial growth. The present speech results will therefore be weighed against the outcome of maxillofacial growth for these patients.
