Overweight and obesity in children: known facts and new trends

The prevalence of overweight and obesity in children is increasing. A growing number of children are thus suffering from complications of obesity. Contributing factors can be found on an individual level as well as in the familial and social environment of affected children. Currently there is no single evidence-based treatment strategy available. Studies from family practice are scarce. Multimodal, long-term, easily accessible treatments as offered in family practice are promising and likely to be cost-effective. The sustainability of these changes in behavior still needs to be demonstrated.

Efficacy and safety of certolizumab pegol in an unselected crohn's disease population: 26-week data of the FACTS II survey

Certolizumab pegol (Cimzia, CZP) was approved for the treatment of Crohn's disease (CD) patients in 2007 in Switzerland as the first country worldwide. This prospective phase IV study aimed to evaluate the efficacy and safety of CZP over 26 weeks in a multicenter cohort of practice-based patients.

Acute Encephalopathy with Unilateral Cortical-Subcortical Lesions in Two Unrelated Kindreds Treated with Glucocorticoids Prenatally for Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency: Established Facts and Novel Insight

Background: Prenatal glucocorticoid (GC) treatment of the female fetus with 21-hydroxylase deficiency (21-OHD) may prevent genital virilization and androgen effects on the brain, but prenatal GC therapy is controversial because of possible adverse effects on fetal programming, the cardiovascular system and the brain. Case Reports: We report 2 patients with congenital adrenal hyperplasia (CAH) due to 21-OHD who were treated prenatally with dexamethasone, suffered from an acute encephalopathy and showed focal and multifocal cortical and subcortical diffusion restrictions in early MRI and signs of permanent alterations in the follow-up neuroimaging studies. Both patients recovered from the acute episode. Whereas the first patient recovered without neurological sequelae the second patient showed hemianopsia and spastic hemiplegia in the neurological follow-up examination. Conclusion: These are 2 children with CAH, both treated prenatally with high doses of dexamethasone to prevent virilization. The question arises whether prenatal high-dose GC treatment in patients with CAH might represent a risk factor for brain lesions in later life. Adverse effects/events should be reported systematically in patients undergoing prenatal GC treatment and long-term follow-up studies involving risk factors for cerebrovascular disease should be performed.

Ankyloglossia: facts and myths in diagnosis and treatment

BACKGROUND: The objective of this study was to systematically review the diagnostic criteria, indications, and need for treatment of ankyloglossia (tongue-tie), as well as the various treatment options for patients in different age groups. METHODS: The MEDLINE databases and the Cochrane Library were searched according to well-defined criteria, resulting in 64 included articles. The evidence regarding the classifications of tongue-tie, epidemiologic data, inheritance, breastfeeding problems, impaired tongue mobility, speech disorders, malocclusion, gingival recessions, therapy, and complications due to surgery was analyzed in detail. RESULTS: Different classifications for ankyloglossia have been proposed but not uniformly accepted. Breastfeeding problems in neonates could be associated with a tongue-tie, but not enough controlled trials have been performed to identify an ideal treatment option. In children and adults with ankyloglossia, limitations in tongue mobility are present, but the individual degree of discomfort, as well as the severity of an associated speech problem, are subjective and difficult to categorize. There is no evidence supporting the development of gingival recessions because of ankyloglossia. Frenotomy, frenectomy, and frenuloplasty are the main surgical treatment options to release/remove an ankyloglossia. Because of the limited evidence available, no specific surgical method can be favored. CONCLUSIONS: The lack of an accepted definition and classification of ankyloglossia makes comparisons between studies almost impossible. Because almost no controlled prospective trials for surgical interventions in patients with tongue-ties are present in the literature, no conclusive suggestions regarding the method of choice can be made. It also remains controversial which tongue-ties need to be surgically removed and which can be left to observation.

Facts and myths regarding the maxillary midline frenum and its treatment: a systematic review of the literature

OBJECTIVE To systematically review the current literature on the maxillary midline frenum and associated conditions and complications, as well as the recommended treatment options. METHOD AND MATERIALS A detailed MEDLINE database search was carried out to provide evidence about the epidemiology, associated pathologies, and treatment options regarding the maxillary frenum. Of the 206 initially identified articles, 48 met the inclusion criteria. RESULTS The maxillary frenum is highly associated with a number of syndromes and developmental abnormalities. A hypertrophic frenum may be involved in the etiology of the midline diastema. There is also a tendency by orthodontists to suggest posttreatment removal of the frenum (frenectomy). Studies on the cause of gingival recession due to the maxillary frenum are inconclusive. An injured frenum in combination with other traumas and doubtful history might point to child abuse. The involvement of hyperplastic frena in the pathogenesis of peri-implant diseases remains uncertain. There seems to be a clinical interest regarding lasers for surgery for treatment of maxillary frena. The superiority of laser treatment in relation to conventional surgical methods has not yet been demonstrated in the literature. CONCLUSION A maxillary frenum is a clinical symptom in numerous syndromic conditions and plays a role in the development of the median midline diastema. Nevertheless, the contribution to gingival recession and peri-implant diseases in the region of the maxillary incisors is rather controversial. Laser techniques are reported as the method of choice for the surgical removal of frena; however, this needs to be substantiated by appropriate prospective controlled studies.

Weeds and endangered herbs have unforeseen dispersal helpers in the agri-environment: gastropods and earthworms

Agri-environmental schemes involving organic farming or set-aside management aim at promoting biodiversity and restoring ecosystem functioning in agrarian landscapes. Application of pesticides in these crop fields is strongly regulated facilitating the spread of weeds but also allowing for the establishment of endangered herbs and a variety of animals.Recent studies found gastropods and earthworms to be legitimate dispersers of seeds of wild plants. We assumed that both groups also playa significant role in the spread and establishment of wild plants within crop fields. Therefore, we are conducting a series of experiments in three different study systems on (1) the role of earthworms and gastropods as dispersers of rare herbs and weeds in an organic rye field in Germany, (2) the seed feeding behavior of gastropods of plants sown in fallow ground in Switzerland, and (3) weed dispersal in irrigated rice fields by golden apple snails in the Philippines.
