- Traumatic injuries to the primary dentition present special problems and the management is often different as compared with the permanent dentition. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialities were included in the task group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care for management of primary teeth injuries. The IADT cannot and does not guarantee favorable outcomes from strict adherence to the guidelines, but believe that their application can maximize the chances of a positive outcome.

- Despite the high heritability of autism spectrum disorders (ASD), characterized by persistent deficits in social communication and interaction and restricted, repetitive patterns of behavior, interests or activities(1), a genetic diagnosis can be established in only a minority of patients. Known genetic causes include chromosomal aberrations, such as the duplication of the 15q11-13 region, and monogenic causes, as in Rett and fragile- X syndromes. The genetic heterogeneity within ASD is striking, with even the most frequent causes responsible for only 1% of cases at the most. Even with the recent developments in nextgeneration sequencing, for the large majority of cases no molecular diagnosis can be established(2-7). Here, we report ten patients with ASD and other shared clinical characteristics, including intellectual disability and facial dysmorphisms caused by a mutation in ADNP, a transcription factor involved in the SWI/ SNF remodeling complex. We estimate this gene to be mutated in at least 0.17% of ASD cases, making it one of the most frequent ASD- associated genes known to date.

- Objective: Osteogenesis imperfecta (OI) is a rare heterogeneous disease of connective tissue leading to varying degrees of bone fragility. The worst form (type II) is peri-natally lethal whereas the mildest form (type I) is compatible with a normal life span. Over 1000 mutations causing OI have been described in the genes encoding collagen type I. As COL1A1 and COL1A2 are large genes, there are still many codon positions where no mutations have been reported and only a fraction of theoretically possible glycine substitutions have been described. In this study the spectrum of mutations causing OI in Sweden will be investigated and genotype–phenotype correlations as well as pharmacogenetics will be studied. Method: All patients with OI cared for at the Uppsala Osteoporosis Unit (Uppsala University Hospital) or Astrid Lindgren's Paediatric Hospital (Karolinska Institutet, Stockholm) were offered to enter the study. Patients from 140 unrelated families with OI accepted participation; 77 type I, 34 type IV, 20 type III, 5 without previous diagnosis and 4 with unclear OI type. Extensive clinical data is currently being collected on enrolled patients. Exons and flanking intron sequences of COL1A1 and COL1A2 are being sequenced in these families. Results: So far 133/140 families have been completely analyzed and in 27 no mutation was found. A total of 120 mutations have been detected, of which 104 are of a typical OI-type. In COL1A1 73 mutations were found and in COL1A2 31 mutations were noted. In 7 families 2 mutations were present, but only one of these was a typical OI-causing mutation. To date 16 amino acid changing mutations that were not of a typical OI-causing type have been noted and the majority of these have an unclear significance. Calculations of delta BMD Z-score response to bisphosphonate treatment did not show a difference in treatment response between groups with different types of OI or between patients with OI type I due to a qualitative vs. a quantitative collagen type I defect. Conclusion: The spectrum of mutations causing OI described in this Swedish cohort is of the expected type, with the exception of the amino acid changing mutations. It is notable that in seven families two separate mutations were identified. Calculations do not support a mutation dependent response to bisphosphonate treatment.
