A tangled web: parental contact with children in kinship care
Authors: Kiraly Meredith , Humphreys Cathy 
Published: January 2013

AbstractContact between parents and children in care is a contested area. Parental contact is recognized to be important, yet may present protective issues; in the kinship care environment, it brings the particular challenges of complex family relationships. Seeking the parents' perspective in a child protection context is difficult and therefore under‐researched. This paper describes a nested study within an Australian research project on family contact in kinship care in which the perspectives of 18 mothers and 2 fathers were sought via in‐depth interviews. Mothers and fathers described strong feelings of disempowerment in the context both of their family and the child protection system. The relationship between parent and caregiver emerged as a significant issue. All of the parents wished to remain in contact with their children in a meaningful way, whether or not they were likely to resume their children's care; however, contact arrangements presented many difficulties for them. Mothers articulated the need for services that are more empowering and respectful, rather than oriented towards them as failed parents. In order to build appropriate models of support and intervention, we argue for a more inclusive conceptual frame for family life that gives greater recognition to the role of non‐custodial parents in the lives of their children.

Published: January 2013

AbstractBackgroundClinical studies on immediate loading of implants in the posterior atrophic maxilla are rare.PurposeThe study aims to evaluate immediate loading of implants placed with sinus membrane elevation without additional grafting material for bone augmentation of the maxillary sinus floor.Materials and MethodsThe study group comprised of 10 patients in whom a total of 10 maxillary sinus floor augmentations were performed. A total of 21 dental implants (1 to 4) were inserted through the residual bone to protrude into the maxillary sinus under the elevated sinus membrane. The implant site was underprepared to improve primary stability. All the implants were inserted with a torque insertion no less than 20 Ncm. Implants were loaded immediately after surgery with a screw‐retained temporary acrylic restoration. Intraoral X‐rays were taken at implant insertion, after 6 months loading, and after 1st and 2nd year of loading. Resonance frequency analysis (RFA) was performed at the time of initial placement and after 6 months of functional loading.ResultsRFA after implant insertion gave an implant stability quotient (ISQ) level with a range from 62 to 72. All implants remained clinically stable during the follow‐up period of 2 years. Radiography demonstrated on average 5.7 ± 3.4 mm of intrasinus new bone formation after 6 months of implant loading. RFA measurements showed ISQ mean values of 67 (range: 62–72) and 68 (range: 62–71) at placement and after 6 months of loading, respectively.ConclusionWithin the limits of this case series report, it is concluded that maxillary sinus membrane elevation with simultaneous placement and immediate loading of implants without the use of any additional grafting material shows predictable results after 2 years of functional loading. Moreover, evidence of intrasinus bone formation around the implants was found in all patients. Further studies are needed to study the influence of immediate loading on the mineralization of bone forming at dental implant sites.

AbstractBackgroundThe treatment of mandibular edentulism with implant fixed complete dental prostheses (IFCDPs) is a routinely used treatment option.PurposeThe study aims to report the implant and prosthodontic survival rates associated withIFCDPsfor the edentulous mandible after an observation period of a minimum 5 years.Materials and MethodsAn electronicMEDLINE/PubMEDsearch was conducted to identify randomized controlled clinical trials and prospective studies withIFCDPsfor the edentulous mandible. Clinical studies with at least 5‐year follow‐up were selected. Pooled data were statistically analyzed and cumulative implant‐ and prosthesis survival rates were calculated by meta‐analysis, regression, and chi‐square statistics. Implant‐related and prosthesis‐related factors were identified and their impact on survival rates was assessed.ResultsSeventeen prospective studies, including 501 patients and 2,827 implants, were selected for meta‐analysis. The majority of the implants (88.5% of all placed implants) had been placed in the interforaminal area. Cumulative implant survival rates for rough surface ranged from 98.42% (95% confidence interval [CI]: 97.98–98.86) (5 years) to 96.86% (95%CI: 96.00–97.73) (10 years); smooth surface implant survival rates ranged from 98.93% (95%CI: 98.38–99.49) (5 years) to 97.88% (95%CI: 96.78–98.98) (10 years). The prosthodontic survival rates for 1‐pieceIFCDPsranged from 98.61% (95%CI: 97.80–99.43) (5 years) to 97.25% (95%CI: 95.66–98.86) (10 years).ConclusionTreatment with mandibularIFCDPsyields high implant and prosthodontic survival rates (more than 96% after 10 years). Rough surface implants exhibited cumulative survival rates similar to the smooth surface ones (p > .05) in the edentulous mandible. The number of supporting implants and the antero‐posterior implant distribution had no influence (p > .05) on the implant survival rate. The prosthetic design and veneering material, the retention type, and the loading protocol (delayed, early, and immediate) had no influence (p > .05) on the prosthodontic survival rates.
Reflections on Communicating Science through Art
Authors: Friedman Alan J. 
Published: January 2013

AbstractIf science can inspire art, can art inspire interest and learning about science? There is widespread experimentation in using the arts as tools for communicating science in science museums and other settings. When the arts work well in communicating important aspects of science, they can be powerful tools. Three artworks are discussed: Particle Fever, a film in development about particle physicists and the hunt for the mysterious Higgs Boson; The Great Immensity, a National Science Foundation‐supported musical about climate change: and Guardians, a ballet co‐produced by and performed in an aquarium. These three art‐and‐science hybrids have given this writer some understanding of at least one way to sift the successful from the unsuccessful ventures.

BackgroundSickle cell anemia (SCA) is the most common inherited anemia. Although heart involvement in SCA is well‐established, there is no data about changes of contraction synchrony in SCA. Therefore, we aimed to study the left ventricular contraction synchrony in SCA patients with narrow QRS and normal ejection fraction (EF).MethodsThirty‐six patients with SCA and 37 age‐ and gender‐matched control subjects were included in the study. Left ventricular dyssynchrony was investigated by color‐coded tissue Doppler imaging.ResultsThe SCA patients had lower hemoglobin (Hb) and higher ferritin, left ventricular end‐diastolic diameter, left ventricular end‐systolic diameter, left ventricular mass index (LVMI), and pulmonary artery pressure. Peak A velocity, Dt, and E/E′ values were higher in the SCA group however, E/A ratio and average Em were higher in the control group. LV systolic dyssynchrony parameters including Ts‐SD‐12, Ts‐12, Ts‐SD‐6, and Ts‐6 were found to be higher in SCA group when compared with controls. In addition to that, the patients with ventricular dyssynchrony (a Ts‐SD‐12 > 34.4 msec) were higher in the SCA group than the control group (55.6% vs. 8.1%, P < 0.001). In the correlation analysis, systolic dyssynchrony parameters were found to be correlated with Hb, ferritin, LVMI, E/A, Dt, Em.ConclusionOur results revealed that in SCA patients with normal EF and narrow QRS, left ventricular systolic dyssynchrony was an early manifestation of heart involvement and might be coexisted with or preceding diastolic dysfunction.

Objectives/BackgroundCongenital aortic stenosis (AS) is the most common obstructive left heart lesion in the young adult population and often complicated by aortic dilatation. Our objective was to evaluate accuracy of aortic imaging with transthoracic echocardiography (TTE) compared with cardiac magnetic resonance (CMR).MethodsAortic diameters were measured at 4 levels by CMR and TTE. Agreement and concordance were assessed by Pearson's correlation and Bland–Altman analysis.ResultsFifty‐nine patients (age 33 ± 8 years; 66% male) with congenital AS and a bicuspid aortic valve (BAV) were included. Aortic diameters were generally smaller with TTE than with CMR. The best correlation was found at the level of the sinotubular junction (R2 = 0.78) with a bias of 1.46 mm (limits of agreement: −5.47 to +8.39 mm). In patients with an aortic aneurysm >40 mm (n = 29) the correlation and agreement between TTE and CMR were found to be less good when compared with patients with normal aortic diameters, especially at the level of the proximal ascending aorta. The correlation and agreement between both imaging modalities were better in patients with type 1 BAV compared with type 2 BAV. Intra‐ and interobserver variability was smaller with CMR (1.8–5.9%) compared with TTE (6.9–15.0%).ConclusionsCMR was found to be superior to TTE for imaging of the aorta in patients with congenital AS, especially at the level of the proximal ascending aorta when an aortic aneurysm is present. Therefore, ideally CMR should be performed at least once to ensure an ascending aortic aneurysm is not missed.

We report an elderly patient presenting with a stroke and also hemolytic anemia secondary to mitral and tricuspid valve repair 3 years earlier, in whom two‐dimensional transesophageal echocardiography (2DTEE) suspected a fistula into the pulmonary artery (APAF) from the posterior wall of the aortic arch. For further assessment, two‐dimensional transthoracic echocardiography (2DTTE) and live/real time three‐dimensional transthoracic echocardiography (3DTTE) were performed. 2DTTE showed findings similar to 2DTEE. Color Doppler guided continuous‐wave Doppler showed continuous flow throughout the cardiac cycle with systolic preponderance across the fistula with a small peak pressure gradient of 22 mmHg. Sequential systematic cropping of the 3D datasets obtained from 3DTTE confirmed that the flow signals originated from the posterior wall of the aortic arch and not the lumen. Thus, 3DTTE served to increase the confidence level that the fistula most likely originated from a vasum vasi in the wall of the aortic arch. To our knowledge, this type of fistula has not been reported previously. Fistulas from the aortic lumen to the pulmonary artery are also rare and so far only 24 cases have been reported in the literature. These are also reviewed by us.

Mini‐AbstractWe present echocardiographic images of a patient with platypnea‐orthodeoxia syndrome associated with the patent foramen ovale that was successfully diagnosed by transesophageal echocardiogram in the sitting position. The postural changes of the patent foramen ovale, which is difficult to detect with transthoracic echocardiography, were dynamically detected by real time three‐dimensional transesophageal echocardiography. Because patients with interatrial communication are not rare, this syndrome might be overlooked in patients with unexplained dyspnea. Therefore, it is necessary to enter this entity in differential diagnosis when one sees alteration of oxygen saturation by posture change.

Mini‐AbstractWe present a case of a 57‐year‐old man with hypertrophic cardiomyopathy and an incidental finding of a left atrial mass. The case highlights the use of multimodality imaging to help characterize the mass. These included cardiac MRI, transthoracic echocardiography, and transesophageal echocardiography (TEE) with three‐dimensional imaging. The use of three‐dimensional TEE best defined the morphologic appearance and attachment of the mass.

Mini‐AbstractA 26‐year‐old woman was referred to our department due to cardiac tumor. She was asymptomatic, and transthoracic echocardiography showed accessory mitral valve tissue (AMVT) associated with cleft mitral valve. There was no left ventricular outflow obstruction, but we could identify the three‐dimensional movement of AMVT and cleft mitral valve. Four‐dimensional transthoracic echocardiography enabled us to reveal the real time movement of these structures precisely. In particular, en face visualization of cleft mitral valve and accessory mitral valve cannot be obtained by two‐dimensional echocardiography.

AbstractAimTo evaluate the influence of different types of mouthguard (MG) on physical performance of female soccer players.Material and methodsThe sample was composed of 25 female soccer players from ‘Guarani Futebol Clube’, age range 18–22 years. For data collection, two tests were performed: agility test (shuttle run) and aerobic capacity and VO2 (Cooper test), in addition to application of a perception questionnaire after wearing mouthguards during the tests.ResultsData analysis showed that mouthguard type III presented better results in the VO2 and aerobic capacity tests (P < 0.05). In relation to difficulties experienced when wearing MGs, there were no reports of pain, discomfort, or nausea. However, 100% of athletes affirmed that it was not possible to speak with MG type I, 80% (n = 20) with type II, and no athlete found difficulty in speaking when wearing MG type III. Distractions were reported by 35% (n = 6) only when athletes wore MG types I and II.ConclusionsAmong the three types evaluated, the customized MG (type III) presented better results in the athletes' physical performance evaluation, even taking into account physical tests performed without the use of mouthguards.
A report of an impacted primary maxillary central incisor tooth

Abstract– Primary tooth impaction is a rare phenomenon when compared to permanent teeth impaction. The purpose of this report is to present a 5‐year‐old Chinese girl who exhibited impaction of tooth 51, its unusual consequence on the permanent successor tooth and its comprehensive management. Her parents revealed that at 6 months of age, the patient had fallen from her bed and struck her face on the floor; however, there were no teeth present in the oral cavity. The intraoral examinations identified a bony‐like projection on the buccal aspect of the alveolus in the 51 region. Radiographic examination revealed that tooth 51 exhibited an unfavourable orientation, with the crown directed towards the palate. Therefore, the impacted tooth 51 was surgically removed, and two years later tooth 11 erupted into the oral cavity with an indentation on its incisal aspect, which resembled the crown of the primary teeth, thus giving the appearance of a tooth within a tooth or ‘dens in dente’. Subsequently, enameloplasty and composite resin build‐up was performed on tooth 11 for aesthetic reasons. It is very unusual to have the clinical crowns of both primary and permanent teeth in such close proximity within the alveolar bone, and the present case is a good example to emphasize that trauma to the primary teeth is of considerable importance due to the close proximity of the primary teeth to permanent tooth germs.

Background and purposePolymorphic paraoxonase (PON1) variants can variably prevent low‐ and high‐density lipoprotein oxidation, but their role in provoking atherosclerosis remained unclear. We addressed this issue by profiling PON1 polymorphisms and enzymatic activities, and assessing atherosclerosis and cerebral arteriosclerosis severity in post‐stroke patients.MethodsCarotid artery intima‐media‐thickness (IMT), cerebral white matter lesions (WML), serum PON1 ‐108C/T, Q192R and L55M polymorphisms, and PON and acetylcholinesterase (AChE) enzyme activities were determined in 237 patients.ResultsGenetic variation at the PON1 locus showed a strong influence on PON1 activity in ischaemic stroke patients, but lacked direct influence on IMT. Stroke patients with PON1 QQ192 or MM55 genotypes demonstrated lower PON and arylesterase activities at both Day 1 and 12 months post‐stroke than patients with either RQ/RR192 or LM/LL55 genotypes (P < 0.001). Furthermore, patients with carotid atherosclerosis and/or cerebral arteriosclerosis expressed as IMT, carotid plaques and WML had lower 12 months PON1 activity than patients without (P = 0.02, P = 0.027 and P = 0.001, respectively), and PON and AChE hydrolysis rates were more tightly correlated in patients carrying the PON1 192R compared with the 192QQ allele, in a gene dose‐dependent manner (P < 0.001).ConclusionOur findings show inverse PON1 activity–carotid atherosclerosis and –cerebral arteriosclerosis association in stroke patients: the lower the PON1 activity the more progressed is the atherosclerotic process and the weaker is the association with AChE activity. Extending previous PON1 genetic studies in stroke populations, our study emphasizes the PON1 activity as a potential anti‐atherogenic element and proposes involvement of cholinesterase activities in its effects.

Background and purposeEpileptic seizures account for 24–40% of all clinical onsets in patients with brain arteriovenous malformations (AVMs).MethodsWe retrospectively reviewed the angioarchitectural features of AVMs associated with seizures in 168 patients admitted to our Department from 1997 to 2012. Patients were dichotomized according to demographic characteristics, type of treatment, bleeding occurrence, and morphological and topographic features. Clinical status at admission and discharge was also recorded. The association of each one of these variables with seizures occurrence was statistically tested. Continuous variables and outcome were compared with Student's t‐test, whereas categorical ones were compared using Fisher's exact test. The independent contribution of some seizures predictors was assessed with a logistic regression model. Associations were considered significant for P < 0.05.ResultsAbout 29% patients showed seizures and 47% bleeding. No significant difference in age and sex was observed between patients with and without seizures. AVMs > 4 cm (P = 0.001) and those fed by dilated arterial feeders (P = 0.02) were associated with increased risk of seizures. A higher risk of seizures occurrence was also observed in cortical AVMs compared with deeper ones (75.5% vs. 55.4%; P = 0.01), and in AVMs fed by middle and posterior cerebral arteries branches compared with the other vessels (81.6% vs. 45.3%; P < 0.001 and 48.9% vs. 23.5%; P = 0.002, respectively). No lobar predisposition was observed. A nidus > 4 cm also appeared as an independent risk factor of seizures occurrence (OR 2.82; 95% CI, 1.26–6.31; P = 0.009) at logistic regression analysis.ConclusionsAVM morphology, especially nidus dimension, appeared to more significantly influence seizures occurrence than their topography.

SummaryReasons for performing studyA previous systematic review highlighted a lack of good evidence regarding the frequency of equine laminitis inGreatBritain.ObjectivesTo estimate the frequency of veterinary‐diagnosed active laminitis in the general horse population ofGreatBritain and to describe the clinical signs present in cases.Study designProspective cohort study.MethodsData on active episodes of equine laminitis were collected from veterinary practitioners.ResultsThe prevalence of veterinary‐diagnosed active laminitis was 0.47% (95% confidence interval [CI] 0.42–0.52%) for the veterinary‐attended population and 0.49% (95%CI0.43–0.55%) for the veterinary‐registered population, suggesting that active episodes of laminitis accounted for nearly one in 200 equine visits and occurred in nearly one in 200 horses registered with veterinary practices. The incidence of veterinary‐diagnosed active laminitis was 0.5 cases per 100 horse‐years at risk (95%CI0.44–0.57). Laminitis occurred in all limbs, but most commonly affected the forelimbs bilaterally (53.5%, 95% CI 49.4–57.7%) and was most severe in the front feet. The most common clinical signs were increased digital pulses, difficulty turning and a short, stilted gait at walk.Conclusions and potential relevanceThe frequency of veterinary‐diagnosed active laminitis was considerably lower than previously published estimates, which is probably due to differences in geographical setting, study period, case definition, study design and study populations.
