RESUMO

PURPOSE: Body dysmorphic disorder (BDD) is a distressing condition involving preoccupation with an imagined or exaggerated deformity. The purpose of our study was to investigate the presence of BDD and its comorbidity with anxiety, depression, and obsessive-compulsive disorder (OCD) in patients undergoing orthognathic surgery (OS). MATERIALS AND METHODS: The present prospective study included 99 patients from the outpatient oral and maxillofacial surgery clinic at Stanford University who requested OS. The incidence of BDD, depression, anxiety, and OCD was assessed preoperatively using validated self-report measures. To determine the prevalence of Axis I psychological symptoms among patients, the descriptive and bivariate statistics were computed. P < .05 was considered significant. RESULTS: In our sample, 13 patients (13%) screened positive for BDD. We did not find any significant correlations between the presence of BDD and gender, race, age, or marital status. Depressive symptoms were reported by 42% of the patients, OCD symptoms by 29%, and mild, moderate, and severe anxiety by 14%, 5%, and 4%, respectively. Using Spearman correlations, we found significant correlations between BDD and anxiety, depression, and OCD (P < .01). CONCLUSIONS: The results of the present study suggest that the rates of BDD, depression, anxiety, and OCD are high in patients undergoing OS. Furthermore, we found a strong correlation between BDD and anxiety, OCD, and depression in these patients. Future studies are necessary to determine the postoperative changes in these psychological disorders and whether these changes are affected by having positive BDD screening results at baseline.

RESUMO

Patients with craniofacial anomalies have an increased incidence of dental caries. The prevention program "Caries Management By Risk Assessment" (CAMBRA) has been previously validated but has not yet been introduced at a widespread level in a medical setting, particularly for this high-risk population.In this cross-sectional study, we aimed to evaluate the feasibility of implementing CAMBRA during the medical visit at an institutional tertiary care center, which treats children with craniofacial anomalies. The study included 161 participants aged 1 to 18 years. Patients and parents received a personalized educational session, toothbrushing tutorial, and fluoride varnish application. We assessed the prevalence of dental caries, caries risk factors, and knowledge of oral hygiene in this patient population.The overall caries prevalence in this group was higher than average (57% compared with 42%, according to the Centers for Disease Control and Prevention). The most prevalent risk factors were developmental delay, deep pits/fissures, low socioeconomic status, orthodontic appliances, and carbohydrate snacks. The greatest predictors of dental caries were having 1 or more risk factors and having low socioeconomic status. In summary, children with craniofacial anomalies were at high risk for dental caries, with high rates of risk factors and low rates of preventive factors.Our findings revealed that basic oral hygiene standards are not being met in this high-risk population, highlighting the need for implementation of protocols such as CAMBRA. The results of this study can aid healthcare workers in craniofacial centers and children's hospitals to improve the understanding of oral hygiene and dental care of their patients.

RESUMO

Cellular sulfation pathways rely on the activated sulfate 3'-phosphoadenosine-5'-phosphosulfate (PAPS). In humans, PAPS is exclusively provided by the two PAPS synthases PAPSS1 and PAPSS2. Mutations found in the PAPSS2 gene result in severe disease states such as bone dysplasia, androgen excess and polycystic ovary syndrome. The APS kinase domain of PAPSS2 catalyzes the rate-limiting step in PAPS biosynthesis. In this study, we show that clinically described disease mutations located in the naturally fragile APS kinase domain are associated either with its destabilization and aggregation or its deactivation. Our findings provide novel insights into possible molecular mechanisms that could give rise to disease phenotypes associated with sulfation pathway genes.

RESUMO

The energy currency of the cell ATP, is used by kinases to drive key cellular processes. However, the connection of cellular ATP abundance and protein stability is still under investigation. Using Fast Relaxation Imaging paired with alanine scanning and ATP depletion experiments, we study the nucleotide kinase (APSK) domain of 3'-phosphoadenosine-5'-phosphosulfate (PAPS) synthase, a marginally stable protein. Here, we show that the in-cell stability of the APSK is determined by ligand binding and directly connected to cellular ATP levels. The observed protein stability change for different ligand-bound states or under ATP-depleted conditions ranges from ΔGf 0 = -10.7 to +13.8 kJ/mol, which is remarkable since it exceeds changes measured previously, for example upon osmotic pressure, cellular stress or differentiation. The results have implications for protein stability during the catalytic cycle of APS kinase and suggest that the cellular ATP level functions as a global regulator of kinase activity.
