Crossbite associated with open bite in primary dentition: case report

Posterior crossbites and anterior open bites can alter a patient's esthetics and function, and affect the balance of the stomatognathic system. Pediatric dentists and orthodontists play an important role in preventing, intercepting, and correcting these problems. This article describes a clinical case that corrected malocclusion that had resulted in simultaneous posterior crossbite and anterior open bite. The article also defends the importance of early treatment for children with this condition and discusses the diverse clinical aspects involved.     

Genotype distribution of clinical isolates of Trichosporon asahii based on sequencing of intergenic spacer 1

The sequence polymorphisms of intergenic transcribed spacer and the antifungal susceptibility profile of 18 Trichosporon asahii isolates from Spain, Argentina, and Brazil together with 43 intergenic transcribed spacer 1 sequences deposited in the GenBank were analyzed. Six genotypes were detected instead of 5 genotypes described previously. Genotype 1 was the most common found comprising 57.3% of all strains, followed by genotype 3 (14.7%) and genotype 5 (13.1%). Spanish strains had members in all genotypes except 2, whereas South American isolates were grouped with genotypes 1, 3, and 6. Our results indicate that all genotypes are present in at least 2 countries suggesting a worldwide distribution. On the other hand, genotype 6 was not previously described but was only composed of 2 South American strains isolated from a subcutaneous abscess and skin. All isolates showed amphotericin B MICs>or=2 mg/L supporting the in vitro resistance of this species to this antifungal. Three isolates from South America showed high MICs to all antifungals analyzed. The true epidemiologic usefulness of classifying T. asahii in genotypes should be ascertaining analyzing a high number of isolates from many countries.     

The effects of photobiomodulation using LED on the repair process of skin graft donor sites

Lasers in Medical Science - The benefits of photobiomodulation (PBM) applied to wounds are well-described in the literature; however, its effects in skin graft donor sites have been poorly studied....     

Growth velocity and interleukin 6 concentrations in juvenile idiopathic arthritis

OBJECTIVE: .To evaluate associations of growth velocity with inflammatory markers and cumulative dose of glucocorticoid in a cohort of patients with juvenile idiopathic arthritis (JIA) followed during 1 year. METHODS: Seventy-nine patients were evaluated. Disease activity was evaluated by a pediatric rheumatologist. Anthropometric data were classified according to the World Health Organization standards. Tanner growth velocity curves were used; values below the Z-score < or = -2 were considered low growth velocity. Serum concentrations of interleukin 6 (IL-6) were measured by ELISA, and values > 1 pg/ml were considered elevated. RESULTS: The prevalence of low growth velocity was 25.3%, and it was associated with active disease on followup visit, elevated IL-6, erythrocyte sedimentation rate and C-reactive protein, and higher cumulative glucocorticoid doses. In the multiple linear regression with growth velocity as the dependent variable, only elevated IL-6 level was independently and negatively associated with growth velocity. CONCLUSION: Low growth velocity is highly prevalent in children with JIA. Elevated IL-6 levels seem to have an important negative influence on growth in these children, while total glucocorticoid exposure appears to be a secondary factor.     

Does age influence the success of intra-tympanic steroid treatment in idiopathic sudden deafness?

Conclusions: The present study shows that AGE, DELAY, and PTA_PRE may be considered factors influencing therapeutic success in intra-tympanic steroid therapy. Objective: The aim of the study is to evaluate the relationship between the therapeutic success of intra-tympanic prednisolone therapy and age, in patients affected by idiopathic sudden sensorineural hearing loss (ISSNHL), considering the influence of factors such as delay, gender, and pure tone average (PTA) pre-therapy. Method: This retrospective study involved 402 consecutive patients, affected by unilateral ISSNHL between January 2009 and January 2014. Patients were divided into two groups based on age: group one with 94 patients aged over 65 years and group two with all 402 patients enrolled in the study, including those over 65. Results: PTA recorded before the beginning of the therapy (PTA_PRE) in group one was worse than for group two. In both groups the therapy was significantly effective in improving hearing thresholds, even if PTA_PRE was significant and negatively correlated with success rate. This effect disappeared within the population over 65. On average, each day of DELAY from the onset of hearing loss to the beginning of therapy cuts almost 2% of the possibility to recover. AGE was negative and significant when specified continuously for group two.     

Negative affect in systemic sclerosis

Negative affect appears frequently in rheumatic diseases, but studies about their importance and prevalence in systemic sclerosis patients are scarce, and the results are inconclusive separately. We conducted a comprehensive search on April 2013 of PubMed, Medline, and PsycINFO databases to identify original research studies published. A total of 48 studies were included in this systematic review. We found negative emotions have very high levels in these patients, compared to both healthy population other chronic rheumatic patients assessed with the same instruments and cutoffs. Depression has been, of the three negative emotions that we approach to in this review, the most widely studied in systemic sclerosis, followed by anxiety. Despite the fact that anger is a common emotion in these diseases is poorly studied. Methodologic issues limited the ability to draw strong conclusions from studies of predictors. Disease-specific symptoms (swollen joints, gastrointestinal and respiratory symptoms and digital ulcers) and factors related to physical appearance were associated with negative emotions. Interdisciplinary care and biopsychosocial approach would have a great benefit in the clinical management of these patients.
