Comparative Prevalence, Correlates of Impairment, and Service Utilization for Eating Disorders Across US Ethnic Groups: Implications for Reducing Ethnic Disparities in Health Care Access for Eating Disorders

Objective: The study compared the prevalence, correlates of functional impairment, and service utilization for eating disorders across Latinos, Asians, and African Americans living in the United States to non-Latino Whites. Method: Pooled data from the NIMH Collaborative Psychiatric Epidemiological Studies (CPES; NIMH, 2007) were used. Results: The prevalence of anorexia nervosa (AN) and binge-eating disorder (BED) were similar across all groups examined, but bulimia nervosa (BN) was more prevalent among Latinos and African Americans than non-Latino Whites. Despite similar prevalence of BED among ethnic groups examined, lifetime prevalence of any binge eating (ABE) was greater among each of the ethnic minority groups in comparison to non-Latino Whites. Lifetime prevalence of mental health service utilization was lower among ethnic minority groups studied than for non-Latino Whites for respondents with a lifetime history of any eating disorder. Discussion: These findings suggest the need for clinician training and health policy interventions to achieve optimal and equitable care for eating disorders across all ethnic groups in the United States.

A randomized, comparative study of formoterol and terbutaline dry powder inhalers in the treatment of mild to moderate asthma exacerbations in the pediatric acute care setting

Background: Formoterol is a fast-acting, long-acting beta-agonist. Its on-demand use by outpatients has been beneficial in controlling asthma. Objective: To evaluate the efficacy of formoterol as rescue medication for pediatric asthma exacerbation. Methods: A randomized, double-blind study was conducted on parallel groups involving 79 pediatric patients (mean [SD] age, 9.92 [2.5] years) with mild to moderate asthma exacerbations. They were treated with up to 3 doses of formoterol aerolizer, 12 mu g, or terbutaline Turbuhaler, 0.5 mg (dry powder inhalers). Respiratory rate, clinical score, pulse oximetry, and spirometry were analyzed at baseline and 15 minutes after administration of each bronchodilator dose. All the patients received oral prednisolone, 1 mg/kg, at study entry, followed by a single daily dose for 4 days. Forty-one patients were treated with formoterol and 38 with terbutaline. The groups were comparable in age and in severity of asthma exacerbation. Results: Both treatments resulted in similar clinical and functional improvement; 37 patients (47%) required 1 bronchodilator dose. Increases of 19.5% and 1.5.3% occurred in forced expiratory volume in 1 second in the formoterol and terbutaline groups, respectively. Therapeutic failures occurred in 2 patients. No adverse effects were observed. At 1-week follow-up, patients were stable, with pulmonary function close to normal. Conclusion: Formoterol therapy was at least as effective as terbutaline therapy in children and adolescents with mild and moderate asthma exacerbations.

Comparative Study of the Standard Fluorescent Antibody to Membrane Antigen (FAMA) Assay and a Flow Cytometry-Adapted FAMA Assay To Assess Immunity to Varicella-Zoster Virus

A flow cytometry-adapted fluorescent antibody to membrane antigen (FAMA) assay to detect IgG antibodies against varicella-zoster virus (VZV) was developed and tested in 62 serum samples, showing 90.32% accuracy obtained from a receiver operating characteristic (ROC) curve with a 0.9125 (95% confidence interval [CI], 0.829 to 1.00) area below the curve compared to the result with standard FAMA.

Comparative study of Botox (R) injection treatment for upper eyelid retraction with 6-month follow-up in patients with thyroid eye disease in the congestive or fibrotic stage

Aim To compare morphometric data of the eyelid fissure and the levator muscle function (LF) before and up to 6 months after transcutaneous injection with five units of Botox (R) in patients with upper lid retraction (ULR) from congestive or fibrotic thyroid eye disease (TED). Methods Twenty-four patients with ULR from TED were submitted to transcutaneous injection of 5 units (0.1 ml) of Botox in one eye only. Patients were divided into two groups: 12 with congestive-stage TED (CG), and 12 with fibrotic-stage TED (FG). Bilateral lid fissure measurements using digital imaging and computer-aided analysis were taken at baseline and at regular intervals 2 weeks, 1 month, 3 months and 6 months after unilateral Botox injection. Mean values taken at different follow-up points were compared for the two groups. Results Most patients experienced marked improvement in ULR, with a mean reduction of 3.81 mm in FG and 3.05 mm in CG. The upper eyelid margin reflex distance, fissure height and total area of exposed interpalpebral fissure were significantly smaller during 1 month in CG and during 3 months in FG. Reduction in LF and in the difference between lateral and medial lid fissure measurements was observed in both groups. The treatment lasted significantly longer in FG than in CG. Conclusions A single 5-unit Botox injection improved ULR, reduced LF and produced an adequate lid contour in patients with congestive or fibrotic TED. The effect lasts longer in patients with fibrotic orbitopathy than in patients with congestive orbitopathy.

Gingival juvenile xanthogranuloma in an adult patient: case report with immunohistochemical analysis and literature review

Juvenile xanthogranuloma (JXG) is a non-Langerhans cell histiocytosis (nonLCH). It is a benign and self-healing disorder that generally affects infants and children. Oral lesions in adult patients are rare, although the microscopic findings are similar to those observed in other locations. A 56-year-old white man presented with a chief complaint of a gingival mass that had appeared 6 months before and had grown slowly. An intraoral examination revealed the presence of a solitary, softened gingival mass affecting the mandibular lingual gingiva at the right central incisor area. A biopsy of the lesion showed multiple large macrophages and numerous giant cells of Touton type. The immunohistochemistry positivity for CD68, fascin, factor XIIIa, alpha-antitrypsin and negativity for S-100, beta-actin, CD1a, and desmin confirmed the diagnosis of JXG. The occurrence of adult oral JXG is extremely rare. It is a nonLCH that may present variable clinical and microscopic aspects, which leads to a diversity of clinical misdiagnoses. A precise diagnosis of these lesions requires an accurate evaluation of clinical, microscopic, and immunohistochemical features.

Hemorrhagic vesicle-bullous lesions in Henoch-Schonlein purpura and review of literature

Introduction: The characteristic feature of Henoch-Schonlein purpura (HSP) is palpable purpura, however hemorrhagic vesicles and blisters have been rarely reported. Case reports: From January 1983 to December 2007, 5079 patients were followed in our Pediatric Rheumatology Unit, 232 (4.6%) of them with the diagnosis of HSP. Three female patients (1.3%) presented hemorrhagic vesicles and bullous lesions associated with palpable purpura. In one case the lesions were severe and widespread, and in another they preceded the typical purpuric lesions. In both cases, skin biopsy disclosed leukocytoclastic vasculitis with IgA and C3 deposits. Two patients healed with residual lesions: ulcers in one case and skin hyperpigmentation in two of them. Discussion: Hemorrhagic vesicle-bullous lesions are rare in HSP This manifestation may represent a more severe and prolonged disease course with scars or may precede typical skin lesions.

High frequency of submicroscopic chromosomal imbalances in patients with syndromic craniosynostosis detected by a combined approach of microsatellite segregation analysis, multiplex ligation-dependent probe amplification and array-based comparative genome hybridisation

We present the first comprehensive study, to our knowledge, on genomic chromosomal analysis in syndromic craniosynostosis. In total, 45 patients with craniosynostotic disorders were screened with a variety of methods including conventional karyotype, microsatellite segregation analysis, subtelomeric multiplex ligation-dependent probe amplification) and whole-genome array-based comparative genome hybridisation. Causative abnormalities were present in 42.2% (19/45) of the samples, and 27.8% (10/36) of the patients with normal conventional karyotype carried submicroscopic imbalances. Our results include a wide variety of imbalances and point to novel chromosomal regions associated with craniosynostosis. The high incidence of pure duplications or trisomies suggests that these are important mechanisms in craniosynostosis, particularly in cases involving the metopic suture.

Comparative effects of wavelengths of low-power laser in regeneration of sciatic nerve in rats following crushing lesion

Peripheral nerves are structures that, when damaged, can result in significant motor and sensory disabilities. Several studies have used therapeutic resources with the aim of promoting early nerve regeneration, such as the use of low-power laser. However, this laser therapy does not represent a consensus regarding the methodology, thus yielding controversial conclusions. The objective of our study was to investigate, by functional evaluation, the comparative effects of low-power laser (660 nm and 830 nm) on sciatic nerve regeneration following crushing injuries. Twenty-seven Wistar rats subjected to sciatic nerve injury were divided into three groups: group sham, consisting of rats undergoing simulated irradiation; a group consisting of rats subjected to gallium-aluminum-arsenide (GaAlAs) laser at 660 nm (10 J/cm(2), 30 mW and 0.06 cm(2) beam), and another one consisting of rats subjected to GaAlAs laser at 830 nm (10 J/cm(2), 30 mW and 0.116 cm(2)). Laser was applied to the lesion for 21 days. A sciatic functional index (SFI) was used for functional evaluation prior to surgery and on days 7, 14, and 21 after surgery. Differences in SFI were found between group 660 nm and the other ones at the 14th day. One can observe that laser application at 660 nm with the parameters and methods utilised was effective in promoting early functional recovery, as indicated by the SFI, over the period evaluated.

Debaryomyces hansenii UFV-1 Intracellular alpha-Galactosidase Characterization and Comparative Studies with the Extracellular Enzyme

Debaryomyces hansenii cells cultivated on galactose produced extracellular and intracellular alpha-galactosidases, which showed 54.5 and 54.8 kDa molecular mass (MALDI-TOF), 60 and 61 kDa (SDS-PAGE) and 5.15 and 4.15 pI values, respectively. The extracellular and intracellular deglycosylated forms presented 36 and 40 kDa molecular mass, with 40 and 34% carbohydrate content, respectively. The N-terminal sequences of the alpha-galactosidases were identical. Intracellular alpha-galactosidase showed smaller thermostability when compared to the extracellular enzyme. D. hansenii UFV-1 extracellular alpha-galactosidase presented higher k(cat) than the intracellular enzyme (7.16 vs 3.29 s(-1), respectively) for the p-nitrophenyl-alpha-D-galactopyranoside substrate. The K(m) for hydrolysis of pNP alpha Gal, melibiose, stachyose, and raffinose were 0.32, 2.12, 10.8, and 32.8 mM, respectively. The intracellular enzyme was acompetitively inhibited by galactose (K(i) = 0.70 mM), and it was inactivated by Cu(II) and Ag(I). Enzyme incubation with soy milk for 6 h at 55 degrees C reduced stachyose and raffinose amounts by 100 and 73%, respectively.

Childhood radiation-associated atypical meningioma with novel complex rearrangements involving chromosomes 1 and 12

Meningiomas are recognized as the most common late complication following radiotherapy. However, cytogenetic studies in childhood atypical radiation-induced meningioma are sporadic, mainly because this condition generally occurs after a long latent period. In the present study we show the results of conventional and molecular cytogenetics in a 14-year-old boy with a secondary atypical meningioma. Apart from numerical changes, we found complex aberrations with the participation of chromosomes 1, 6 and 12. The invariable presence of loss of 1p was demonstrated by fluorescent in situ hybridization (FISH) analysis with probes directed to telomeric regions and by comparative genome hybridization (CGH). Previous cytogenetic studies on adult spontaneous and radiation-associated meningiomas showed loss of chromosome 22 as the most frequent change, followed by loss of the short arm of chromosome 1. To the best of our knowledge this is the first report of highly complex chromosome aberrations in the pediatric setting of meningioma.

Comparative role of neuropsychological testing in the presurgical evaluation of children with medically intractable epilepsies

In the present study, we evaluated the preoperative demographic, clinical, and neuropsychological variables that could predict postoperative seizure outcome in a group of pediatric epileptic patients. We studied 40 consecutive pediatric patients, ages ranging from 6 to 16 years, that underwent resective surgery for the treatment of medically intractable epilepsy at the Clinical Hospital of RibeirA o pound Preto School of Medicine. We performed ictal electroencephalography (EEG), interictal EEG, magnetic resonance imaging (MRI), and a preoperative neuropsychological assessment in the presurgical workup. The following factors were correlated with seizure outcome: (1) duration of epilepsy, (2) surgery localization, (3) localized Neuropsychological (NPS) Evaluation, (4) ictal EEG, (5) interictal EEG, and (6) MRI. Mental retardation, NPS tests, and the other demographic variables failed to correlate with seizure reduction. The identification of predictor variables of epilepsy surgery outcome could improve the epileptic prognosis and guarantee the children`s full potential development.
