Unicystic ameloblastoma of the mandible - an unusual case report and review of literature

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is the second most common odontogenic neoplasm, and only odontoma outnumbers it in reported frequency of occurrence. Its incidence, combined with its clinical behavior, makes ameloblastoma the most significant odontogenic neoplasm. Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. It accounts for 5-15% of all intraosseous ameloblastomas. We report a case of unicystic ameloblastoma in a 30-year-old female, and review the literature

A Comparison of Interventions for Children with Cerebral Palsy to Improve Sitting Postural Control: A Clinical Trial

Background The ability to sit independently is fundamental for function but delayed in infants with cerebral palsy (CP). Studies of interventions directed specifically toward sitting in infants with CP have not been reported. Objective The purpose of this study was to compare 2 interventions for improving sitting postural control in infants with CP. Design For this randomized longitudinal study, infants under 2 years of age and at risk for CP were recruited for intervention directed toward sitting independence. Setting The intervention was conducted at home or at an outpatient facility. Patients and Intervention Fifteen infants with typical development (mean age at entry=5 months, SD=0.5) were followed longitudinally as a comparison for postural variables. Thirty-five infants with delays in achieving sitting were recruited. Infants with delays were randomly assigned to receive a home program (1 time per week for 8 weeks; mean age=15.5 months, SD=7) or a perceptual-motor intervention (2 times per week for 8 weeks; mean age=14.3 months, SD=3). Measurements The primary outcome measure was center-of-pressure (COP) data, from which linear and nonlinear variables were extracted. The Gross Motor Function Measure (GMFM) sitting subsection was the clinical outcome measure. Results There was a main effect of time for the GMFM sitting subscale and for 2 of the COP variables. Interaction of group × time factors indicated significant differences between intervention groups on 2 COP measures, in favor of the group with perceptual-motor intervention. Limitations The small number of infants limits the ability to generalize the findings. Conclusions Although both groups made progress on the GMFM, the COP measures indicated an advantage for the group with perceptual-motor intervention. The COP measures appear sensitive for assessment of infant posture control and quantifying intervention response

Study protocol: an early intervention program to improve motor outcome in preterm infants: a randomized controlled trial and a qualitative study of physiotherapy performance and parental experiences

Background Knowledge about early physiotherapy to preterm infants is sparse, given the risk of delayed motor development and cerebral palsy. Methods/Design A pragmatic randomized controlled study has been designed to assess the effect of a preventative physiotherapy program carried out in the neonatal intensive care unit. Moreover, a qualitative study is carried out to assess the physiotherapy performance and parents' experiences with the intervention. The aim of the physiotherapy program is to improve motor development i.e. postural control and selective movements in these infants. 150 infants will be included and randomized to either intervention or standard follow-up. The infants in the intervention group will be given specific stimulation to facilitate movements based on the individual infant's development, behavior and needs. The physiotherapist teaches the parents how to do the intervention and the parents receive a booklet with photos and descriptions of the intervention. Intervention is carried out twice a day for three weeks (week 34, 35, 36 postmenstrual age). Standardized tests are carried out at baseline, term age and at three, six, 12 and 24 months corrected age. In addition eight triads (infant, parent and physiotherapist) are observed and videotaped in four clinical encounters each to assess the process of physiotherapy performance. The parents are also interviewed on their experiences with the intervention and how it influences on the parent-child relationship. Eight parents from the follow up group are interviewed about their experience. The interviews are performed according to the same schedule as the standardized measurements. Primary outcome is at two years corrected age. Discussion The paper presents the protocol for a randomized controlled trial designed to study the effect of physiotherapy to preterm infants at neonatal intensive care units. It also studies physiotherapy performance and the parent's experiences with the intervention

Russian Public Diplomacy: Questioning Certainties in Uncertain Times

In this chapter, we first outline Russia’s strategic thinking on public diplomacy and information security, then go on to examine the relationships between the ways in which Russian politicians, and the two public diplomacy outlets, RT and Sputnik, responded to three key junctures in this recent disruptive media event – the 2018 poisoning of the Skripals in Salisbury. The evidence suggests that although cases pertaining to security provide fertile ground for Russian public diplomacy to thrive by mobilising their inherent uncertainty and channelling scepticism towards mainstream sources of information, the realities of the global media environment make the process of managing uncertainty far from simple

Mounting media pressure: Push and pull forces influencing agendas, resource allocation and decision-making in public bureaucracies

Decision-making in public bureaucracies should be guided by rules and formal procedures, securing predictability, impartiality and fair decisions. Studies show that public bureaucracies are highly mediatised – but knowledge about media impact on political outcomes is scarce. In this article, we study if, how and why media affect agendas, resource allocation and case decisions within public bureaucracies. Empirically, we apply a mixed method approach to the case of Norway, utilising a comprehensive survey among civil servants in ministries and agencies, as well as in-depth interviews with civil servants and political leaders. The results clearly support the notion that media can influence agendas, resource allocation and decision-making in ministries and agencies. When media pressure and broad public support build up, action is particularly taken when the issues are deemed important by political actors, suggesting that both push and pull forces are involved when media influence public bureaucracies

Long-term motor outcomes of very preterm and/or very low birth weight individuals without cerebral palsy:a review of the current evidence

Abstract We reviewed literature on long-term motor outcomes of individuals aged five years or older born very preterm (VP: ≤32 weeks of gestation) or with very low birth weight (VLBW: ≤1500g), without cerebral palsy (CP). PubMed produced 2827 articles, whereof 38 were eligible. Assessed by standardised and norm-based motor tests, the Movement Assessment Battery for Children being the most widely used, VP/VLBW individuals showed poorer motor skills compared with term-born controls with differences of approximately 1 SD in magnitude. Some studies assessed subdomains and differences were present in fine motor/manual dexterity, ball skills and gross motor/balance. Prevalence of motor problems varied largely from 8–37% in studies with cut-off at the 5th percentile or −1.5 SD to 12–71% in studies with cut-off at the 15th percentile or −1 SD. This review shows that the degree of motor impairments continues to be substantial among VP/VLBW individuals who do not develop CP

Maternal alcohol and drug use during pregnancy affects the motor behaviour and general movements of infants aged 3–4 months

Background Exposure of alcohol and/or other addictive drugs in pregnancy is a documented risk factor for later neurological impairment. Aims The aim of the study was to determine whether infants suffering from prenatal exposure to addictive drugs and alcohol develop an abnormal motor behaviour at three to four months of age. Study design Controlled cohort study of infants exposed to alcohol and/or other addictive drugs in pregnancy who were recruited from a hospital follow-up programme. The control group consisted of healthy, unexposed infants. Subjects The study group of 108 infants exposed to alcohol and/or addictive drugs in pregnancy were enrolled based on referrals from primary health care. The control group included 106 infants who had not been exposed to the aforementioned substances. Outcome measures We assessed the general movements (Prechtl’s General-Movement-Assessment, GMA), the motor repertoire (Assessment-of-Motor-Repertoire, AMR), and the Alberta-Infant Motor-Scale (AIMS) in all infants at three to four months of age. Results None of the infants in either group had absent fidgety movements (FMs). In the study group 5(5%) had exaggerated FMs and 5(5%) had sporadic FMs; and 68(63%) infants in the study group displayed an abnormal movement character, compared to 23(22%) in the control group (p<0.001). On the AIMS, 46(44%) infants in the study group scored below the 10th percentile, compared to 2(3%) controls (p< 0.001). Conclusion The study describes an abnormal movement character of infants exposed to alcohol and/or addictive drugs in pregnancy when their motor repertoire was assessed at three to four months of age. The AIMS also showed negative effects on their motor behaviour
