Prediction of orthognathic surgery need in children with unilateral cleft lip palate : Dental arch relationships and 5-year-olds' index

Objective To evaluate whether dental arch relationships at 6 years of age can categorize treatment outcome and predict later need for orthognathic surgery in children with unilateral cleft lip and palate (UCLP). Setting and sample population A retrospective longitudinal single-centre study. The study sample comprised 70 consecutive non-syndromic children (47 boys) with complete UCLP operated on by pushback techniques during 1981-1989 and followed until early adulthood in the same cleft centre. Materials and methods Dental casts and maxillomandibular relationships were assessed before orthodontic treatment and secondary alveolar bone grafting at mean age 6.1 years (range 5.6-6.8) using the 5-year-olds' index and lateral cephalograms. The need for orthognathic surgery was retrieved from patient files. Student's t test, Pearson's correlation, and Kappa statistics were used in statistical analyses. Results Orthognathic surgery frequency was 41% (29/70). Those needing orthognathic surgery comprised all 3 patients with an index score of 5 (very poor), 14 of 17 (82%) scoring 4 (poor), 10 of 26 (38%) scoring 3 (fair), and 2 of 19 (11%) scoring 2 (good). Of the five patients with index score 1 (excellent), none needed osteotomies. The mean index score was 2.9. The score was significantly better in those without orthognathic surgery (2.4 versus 3.6). A significant negative correlation existed between the 5-year-olds' index and cephalometric angles ANB and anb. Conclusion The use of 5-year-olds' index may help to predict treatment outcome and the clinical need for orthognathic surgery especially in patients with the lowest and highest index scores.Peer reviewe

Melanophila formaneki (Jakobson) (Coleoptera, Buprestidae) new to Finland

The buprestid Melanophila formaneki (Jakobson) (= Phaenops aerea Formanek) is reported for the first time from Finland. The beetles (5 adults and 32 larvae) were reared from three stems of recently dead approx. 4-m-high Scots pines (Pinus sylvestris L.). The pines had been cut in a heavily polluted industrial arca at Harjavalta, southwestern Finland, in 1989. A specimen collected in 1929 from Sakkola, on the Karelian Isthmus, was redetermined in museum material. M.formaneki is compared with M. cyanea, and the la¡va is described

Wing variation of Maculinea arion (Linnaeus) in Finland (Lepidoptera, Lycaenidae)

Wing variation in the large blue butterfly, Maculinea arion (Linnaeus, 1758), was studied using 22 measurements of the wing shape, venation and coloration in males and females of Finnish and Karelian populations. The results showed that the spots were fewer and smaller in the western populations than in the eastern ones, whereas the black marginal stripe was wider in the west. The samples from the western populations (Lohja, Kangasala, Hattula, Asikkala, etc.) formed a distinctive group differing from the eastern populations (Taipalsaari, Liperi, Isthmus of Karelia). The temporal within-population variation in Asikkala was relatively high compared to the between-population variation within both the western and eastern population groups

Gynandromorphic individuals of Neodiprion sertifer (Hymenoptera, Diprionidae)

Six gynandromorphic individuals of Neodiprion sertifer (Geoffrey) are described from Finland. They were bilaterally gynandromorphic, mosaic-like gynandromorphic or only showed such characters in their head or abdomen
