Altered cardiovascular rhythmicity in children with white coat and ambulatory hypertension

Adults with ambulatory hypertension or white coat hypertension (WCH) display abnormal cardiovascular rhythms. We studied cardiovascular rhythms by Fourier analysis of 24-h ambulatory blood pressure (BP) measurement profiles in 129 hypertensive children, 54 children with WCH, and 146 age-, height-, and gender-matched healthy subjects. The day/night mean arterial pressure ratio was lower in hypertensive and patients with WCH compared with controls (1.13 versus 1.16 versus 1.21, respectively; p < 0.0001). Eighty-five percent of controls were dippers compared with 74% of WCH (n.s.) and 64% of patients with ambulatory hypertension (p < 0.0001). The prevalence of 24-h rhythms was similar among the groups, but prevalence of 12-h BP rhythms was increased in hypertensive (67%) and WCH (72%) compared with controls (51%, p < 0.0001). The amplitudes of the 24-, 8-, and 6-h BP rhythms were reduced in hypertensive and WCH compared with controls (p < 0.05). Hypertensive and patients with WCH displayed delayed 24-, 12-, 8-, 6-h acrophases in comparison with controls (p < 0.05). In conclusion, hypertensive children exhibit abnormal cardiovascular rhythmicity compared with controls, especially a higher prevalence of nondipping compared with normotensive children. Abnormalities in patients with WCH are intermediate between healthy children and patients with ambulatory hypertension.

Dental arch relationship in children with complete unilateral cleft lip and palate following one-stage and three-stage surgical protocols

The objective of this study is to compare dental arch relationship following one-stage and three-stage surgical protocols of unilateral cleft lip and palate. Dental casts of 61 children (mean age, 11.2 years; SD, 1.7), consecutively treated in one center with one-stage closure of the complete cleft at 9.2 months (SD, 2.0), were compared with a sample of 97 patients (mean age, 8.7 years; SD, 0.9), consecutively treated with a three-stage protocol including delayed hard palate closure in another center. The dental casts were assigned random numbers to blind their origin. Four raters graded dental arch relationship and palatal morphology using the EUROCRAN index. The strength of agreement of rating was assessed with kappa statistics. Independent t tests were run to compare the EUROCRAN scores between one-stage and three-stage samples, and Fisher's exact tests were performed to evaluate differences of distribution of the EUROCRAN grades. The intra- and inter-rater agreement was moderate to very good. Dental arch relationship in the one-stage sample was less favorable than in three-stage group (mean scores, 2.58 and 1.97 for one-stage and three-stage samples, respectively; p?in the one-stage sample was more favorable than in the three-stage group (mean scores, 1.79 and 1.96 for one-stage and three-stage samples, respectively; p?=?0.047). The dental arch relationship following one-stage repair was less favorable than the outcome of three-stage repair. The palatal morphology following one-stage repair, however, was more favorable than the outcome of three-stage repair.

Trauma mechanisms, patterns of injury, and outcomes in a retrospective study of 71 burns from civil gas explosions

Although explosion injuries caused by terror attacks or in war are evaluated in many studies, limited information about civil explosion injuries can be found in the literature.

The association between extra-curricular sport participation and social anxiety symptoms in children

Social anxiety is a common psychological complaint that can have a significant and long-term negative impact on a child’s social and cognitive development. In the current study, the relationship between sport participation and social anxiety symptoms was investigated. Swiss primary school children (N = 201), parents, and teachers provided information about the children’s social anxiety symptoms, classroom behavior, and sport involvement. Gender differences were observed on social anxiety scores, where girls tended to report higher social anxiety symptoms, as well as on sport activity, where boys engaged in more sport involvement. MANCOVAs with gender as covariant showed no differences in social anxiety symptoms between children involved in an extracurricular sport and those not engaged in sport participation. Nevertheless, children engaged in team sports displayed fewer physical social anxiety symptoms than children involved in individual sports.

Cavernous malformations of the central nervous system in children: presentation, treatment and outcome of 20 cases

Cavernous malformations (CM) of the central nervous system are vascular malformations responsible for symptoms such as seizures, headache, and neurological deficits: 25% of cases already present in childhood.

Effect of selective dorsal rhizotomy on gait in children with bilateral spastic paresis: kinematic and EMG-pattern changes

Selective dorsal rhizotomy (SDR) is an effective treatment for reducing spasticity and improving gait in children with spastic cerebral palsy. Data concerning muscle activity changes after SDR treatment are limited.

Patterns of frontobasal and frontosinal fractures in children and teenagers relative to developmental stage of the facial skeleton

To clarify the patterns of frontobasal and frontosinal fractures in children and teenagers and to analyze whether the patterns relate to developmental stage of the facial skeleton.

Morphological integration between the cranial base and the face in children and adults

The primary aim of the present study was to assess morphological covariation between the face and the basicranium (midline and lateral), and to evaluate patterns of integration at two specific developmental stages. A group of 71 children (6-10 years) was compared with a group of 71 adults (20-35 years). Lateral cephalometric radiographs were digitized and a total of 28 landmarks were placed on three areas; the midline cranial base, the lateral cranial base and the face. Geometric morphometric methods were applied and partial least squares analysis was used to evaluate correlation between the three shape blocks. Morphological integration was tested both with and without removing the effect of allometry. In children, mainly the midline and, to a lesser extent, the lateral cranial base were moderately correlated to the face. In adults, the correlation between the face and the midline cranial base, which ceases development earlier than the lateral base, was reduced. However, the lateral cranial base retained and even strengthened its correlation to the face. This suggests that the duration of common developmental timing is an important factor that influences integration between craniofacial structures. However, despite the apparent switch of primary roles between the cranial bases during development, the patterns of integration remained stable, thereby supporting the role of genetics over function in the establishment and development of craniofacial shape.

Occurrence and severity of concomitant injuries in other areas than the face in children with mandibular and midfacial fractures

To clarify the occurrence, causes, severity, and predictors of concomitant injuries in pediatric patients with facial fractures.

Systemic therapy of atopic dermatitis in children and adults

Systemic therapy is required in patients with severe atopic dermatitis (AD) refractory to adequate topical therapy. The aim of a systemic therapy is the rapid and efficient improvement of skin symptoms and pruritus in acute exacerbation and/or the long-term control of severe chronic disease. A number of immunosuppressive and immunomodulating substances are available that may efficiently reduce skin inflammation and thus lead to a relief of symptoms including pruritus. The excellent effects of cyclosporine as short-term as well as maintenance therapy have been documented in several studies in children and adults. Furthermore, other immunosuppressive substances such as azathioprine, mycophenolate mofetil and methotrexate are effective in patients with moderate to severe AD. Intravenous immunoglobulins and γ-interferon exert immunomodulatory effects and thus may improve severe AD. Biological agents are a new approach in AD therapy since they may specifically target cells, cytokines or mediators involved in the pathogenesis of AD.

Reproducibility of acute mountain sickness in children and adults: a prospective study

Although a history of previous acute mountain sickness (AMS) is commonly used for providing advice and recommending its prophylaxis during subsequent exposure, the intraindividual reproducibility of AMS during repeated high-altitude exposure has never been examined in a prospective controlled study.
