Temporomandibular Disorders in Burning Mouth Syndrome Patients: An Observational Study

BACKGROUND: Burning Mouth Syndrome (BMS) is a chronic disease characterized by absence of any lesions and burning of the oral mucosa associated to a sensation of dry mouth and/or taste alterations. The purpose of our study is to estimate signs and symptoms of Temporomandibular Disorders (TMD) in patients with BMS and to investigate for the existence of an association between BMS and TMD.MATERIALS AND METHODS: Forty-four BMS patients were enrolled; BMS subtype was established according to the classification of Lamey. After a gnathological evaluation, according to the protocol of the European Academy of Craniomandibular Disorders, patients were classified by RDC/TMD criteria. The data were compared and analyzed using a chi-square test to describe the existence of an association between BMS and TMD.RESULTS: 65.9% the BMS patients showed disorders classified as primary signs and symptoms of TMD according to RDC / TMD criteria, and 72.7% showed parafunctional habits. The chi-square test revealed a statistically significant association (p = 0.035) between BMS and TMD.CONCLUSION: The data suggest that there is a possible relationship not yet well understood between BMS and TMD, may be for neurophatic alterations assumed for BMS that could be also engaged in TMD pathogenesis.     

Profiling celiac disease antibody repertoire

The aim of this study was to dissect the autoantibody response in celiac disease (CD) that remains largely unknown, with the goal of identifying the disease-specific autoantigenic protein pattern or the so called epitome. Sera from CD patients were used to select immunoreactive antigens from a cDNA phage-display library. Candidate genes were identified, the corresponding proteins produced and their immunoreactivity validated with sera from CD patients and controls. Thirteen CD-specific antigens were identified and further validated by protein microarray. The specificity for 6 of these antigens was confirmed by ELISA. Furthermore we showed that this antibody response was not abolished on a gluten free diet and was not shared with other autoimmune diseases. These antigens appear to be CD specific and independent of gluten induction. The utility of this panel extends beyond its diagnostic value and it may drive the attention to new targets for unbiased screens in autoimmunity research.     

Linear β-amino alcohol catalyst anchored on functionalized magnetite nanoparticles for enantioselective addition of dialkylzinc to aromatic aldehydes

A linear β-amino alcohol ligand, previously found to be a very efficient catalyst for enantioselective addition of dialkylzinc to aromatic aldehydes, has been anchored on differently functionalized superparamagnetic core–shell magnetite–silica nanoparticles (1a and 1b). Its catalytic activity in the addition of dialkylzinc to aldehydes has been evaluated, leading to promising results, especially in the case of 1b for which the recovery by simple magnetic decantation and reuse was successfully verified.

Spontaneous regression of cystic dysplasia of the rete testis in an 18-month-old boy: the key role of ultrasonography

Cystic dysplasia of the rete testis (CDT) is a rare cause of scrotal swelling in children. It is a congenital disorder and it can be associated with other genitourinary abnormalities. At present, there is no clear consensus on treatment. Surgical approach has traditionally been the treatment of choice, while, more recently, conservative approach has been applied, justified by the benign nature of the lesion and after few cases of spontaneous regression have been documented. Ultrasonography, supported by negative tumor markers, plays a key role in the diagnostic work up and during observational follow-up. We report a further case of spontaneous regression of suspected CDT in an 18-month-old boy, who has been followed with clinic and ultrasonographic checks.     

Allergen immunotherapy for respiratory allergy: Quality appraisal of observational comparative effectiveness studies using the REal Life Evidence AssessmeNt Tool. An EAACI methodology committee analysis

BackgroundObservational comparative effectiveness studies in allergen immunotherapy (AIT) represent an important evidence source answering research questions that can be challenging to obtain from randomized controlled trials (RCTs), such as long‐term benefits of AIT, the effects on asthma prevention and the onset of new allergen sensitizations. However, observational studies are prone to several sources of bias, which limit their reliability.The REal Life Evidence AssessmeNt Tool (RELEVANT) was recently developed to assist in quality appraisal of observational comparative research to enable identification of useful nonrandomized studies to be considered within guideline development.ObjectiveTo systematically appraise the quality of published observational comparative AIT studies using RELEVANT.MethodsObservational studies comparing AIT to pharmacotherapy for respiratory allergies, assessing as outcome measures reduction of symptoms and/or medication use reduction, were retrieved by computerized bibliographic searches. According to RELEVANT, a failure to meet any one of primary items (background, design, measures, analysis, results, discussion/interpretation, and conflict of interest) represents a critical flaw, significantly undermining the validity of the study results.ResultsThe 14 studies identified supported the benefit of AIT in real‐life, which persists after treatment discontinuation. However, none of them met all the 7 primary RELEVANT criteria. The main defects were reported in the design (28.6% of studies), measures and analysis (64.3% of studies), and results (78.6% of studies) items, due to selection bias and lack of methods for adjusting controls. Half of the studies did not report on conflict of interest.ConclusionThere is a need for more robust observational research in AIT. RELEVANT appears as an easy‐to‐use and sensitive tool for quality appraisal in AIT studies.     

A Project to Implement Use of 40% Dextrose Gel for Transient Neonatal Hypoglycemia

ObjectiveTo examine the effect of oral dextrose gel and oral feedings on newborns’ blood sugar homeostasis in the first day of life in an effort to decrease transfers to the NICU.DesignEvidence-based practice project.Setting/Local ProblemObstetric service at a large hospital in northeast Ohio with approximately 5,300 births annually. Neonates who experienced hypoglycemia were often transferred to the NICU for management if treatment measures failed, thereby increasing the cost of care and separating mothers from their newborns. During 2018, there were 54 neonates transferred to the NICU for hypoglycemia.ParticipantsPediatricians, neonatologists, neonatal nurse practitioners, clinical nurse specialists, managers, educators, and registered nurses.Intervention/MeasurementsAn interdisciplinary task force created a nurse-driven protocol and associated order set and also created and provided interdisciplinary education to all involved caregivers using a multimodal approach. Neonates’ charts were audited for the time period of April 2019 to April 2020 to evaluate participants’ compliance with the prescribed practice changes.ResultsThe number of neonates who qualified for blood glucose testing per the new protocol totaled 1,369. Of these, 188 (14%) met criteria for and were treated with 40% dextrose gel. Treatment with 40% dextrose gel was unsuccessful for 25 neonates, who were then transferred to the NICU. This is 29 fewer than were transferred in 2018.ConclusionThe use of oral dextrose gel and oral feedings was associated with a decrease in the number of newborns transferred to a higher level of care for treatment of hypoglycemia.
