The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase.Electronic supplementary materialThe online version of this article (10.1186/s13052-018-0525-6) contains supplementary material, which is available to authorized users.
The aim of the study was to investigate the use of a hyaluronic acid/polycaprolactone material for meniscal tissue engineering and to evaluate the tissue regeneration after the augmentation of the implant with expanded autologous chondrocytes. Eighteen skeletally mature sheep were treated. The animals were divided into three groups: cell-free scaffold, scaffold seeded with autologous chondrocytes, and meniscectomy alone. The implant was sutured to the capsule and to the meniscal ligament. At a 12-month gross assessment, histology and histomorphometry were used to assess the meniscus implant, knee joint, and osteoarthritis development. All implants showed excellent capsular ingrowth at the periphery. The implant gross assessment showed significant differences between cell-seeded and cell-free groups (p=0.011). The histological analysis indicated a cellular colonization throughout the implanted constructs. Avascular cartilaginous tissue formation was significantly more frequent in the cell-seeded constructs. Joint gross assessment showed that sheep treated with scaffold implantation achieved a significant higher score than those underwent meniscectomy (p<0.0005), and the Osteoarthritis Research Society International score showed that osteoarthritic changes were significantly less in the cell-seeded group than in the meniscectomy group (p=0.047), even though results were not significantly superior to those of the cell-free scaffold. Seeding of the scaffold with autologous chondrocytes increases its tissue regeneration capacity, providing a better fibrocartilaginous tissue formation. The study suggests the potential of the novel hyaluronic acid/polycaprolactone scaffold for total meniscal substitution, although this approach has to be further improved before being applied into clinical practice.
The purpose of the present study was to make a histological analysis of the remodelling process of hamstring tendon graft used as Anterior Cruciate Ligament (ACL). The hamstring graft of eight patients was biopsied at different follow-up times from 1 to 10 years. The specimens were analysed with transmission electron microscopy (TEM) at ultrastructural level comparing them with a native ACL and a native hamstring graft. The hamstring graft was found to undergo ultrastructural changes in terms of number and diameter of fibrils with the major changes occurring in the first 2 years. At longer times after surgery (48 and 120 months) no important further changes were evident and the ultrastructure did not vary substantially from 2 to 10 years. In conclusion, the hamstring tendon used as ACL graft undergoes a transformation process but does not match the ultrastructure pattern of a normal ACL up to 10 years.
This study confirmed that dynamics of correction in clinical setting correspond essentially to theoretical principles of Ponseti method. Muscle abnormalities are not uncommon in clubfeet and have great influence on the progression of correction. If abnormalities are recorded, their evolution along the treatment should be monitored. A more objective evaluation would be required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
