Salivary biomarkers for diagnosis of systemic diseases and malignant tumors. A systematic review
Saliva evaluation could be a possible alternative to blood and/or tissue analyses, for researching specific molecules associated to the presence of systemic diseases and malignancies. The present systematic review has been designed in order to answer to the question ?are there significant associations between specific salivary biomarkers and diagnosis of systemic diseases or malignancies??. The Preferred Reporting Item for Systematic Reviews and Meta-analysis (PRISMA) statement was used to guide the review. The combinations of ?saliva? and ?systemic diseases? or ?diagnosis? or ?biomarkers? or ?cancers? or ?carcinoma? or ?tumors?, were used to search Medline, Scopus and Web of Science databases. Endpoint of research has been set at May 2019. Studies were classified into 3 groups according to the type of disease investigated for diagnosis: 1) malignant tumors; 2) neurologic diseases and 3) inflammatory/metabolic/cardiovascular diseases. Assessment of quality has been assigned according to a series of questions proposed by the National Institute of Health. Level of evidence was assessed using the categories proposed in the Oxford Center for Evidence-Based medicine (CEMB) levels for diagnosis (2011). Seventy-nine studies met the inclusion and exclusion criteria. Fifty-one (64%) investigated malignant tumors, 14 (17.5%) neurologic and 14 (18.5%) inflammatory/cardiovascular/metabolic diseases. Among studies investigating malignant tumors, 12 (23.5%) were scored as ?good? and 11 of these reported statistically significant associations between salivary molecules and pathology. Two and 5 studies were found to have a good quality, among those evaluating the association between salivary biomarkers and neurologic and inflammatory/metabolic/cardiovascular diseases, respectively. The present systematic review confirms the existence of some ?good? quality evidence to support the role of peculiar salivary biomarkers for diagnosis of systemic diseases (e.g. lung cancer and EGFR)
Does Head Orientation Influence 3D Facial Imaging? A Study on Accuracy and Precision of Stereophotogrammetric Acquisition
This study investigates the reliability and precision of anthropometric measurements
collected from 3D images and acquired under different conditions of head rotation. Various sources
of error were examined, and the equivalence between craniofacial data generated from alternative
head positions was assessed. 3D captures of a mannequin head were obtained with a stereophotogrammetric
system (Face Shape 3D MaxiLine). Image acquisition was performed with no rotations
and with various pitch, roll, and yaw angulations. On 3D images, 14 linear distances were measured.
Various indices were used to quantify error magnitude, among them the acquisition error, the mean
and the maximum intra- and inter-operator measurement error, repeatability and reproducibility
error, the standard deviation, and the standard error of errors. Two one-sided tests (TOST) were
performed to assess the equivalence between measurements recorded in different head angulations.
The maximum intra-operator error was very low (0.336 mm), closely followed by the acquisition
error (0.496 mm). The maximum inter-operator error was 0.532 mm, and the highest degree of error
was found in reproducibility (0.890 mm). Anthropometric measurements from alternative acquisition
conditions resulted in significantly equivalent TOST, with the exception of Zygion (l)–Tragion (l) and
Cheek (l)–Tragion (l) distances measured with pitch angulation compared to no rotation position.
Face Shape 3D Maxiline has sufficient accuracy for orthodontic and surgical use. Precision was not
altered by head orientation, making the acquisition simpler and not constrained to a critical precision
as in 2D photographs
Are the Reasons Why Patients Are Referred for an Orthodontic Visit Correct?
Abstract: Who does refer patients for an orthodontic consultation? Which are the main reasons for
the referral? Does the visit of the orthodontic specialist confirm these reasons or reveal undiagnosed
problems? Is there the risk that only evident dental problems are addressed, while craniofacial
malformations remain underdiagnosed? This cross-sectional epidemiologic study aims to answer
these questions, analysing the clinical data collected during the orthodontic visits of 500 Caucasian
young patients referred to a public health structure of northern Italy. All patients were visited by
the same expert specialist in orthodontics. Clinical data were collected, analysing both dental and
skeletal features. The reasons for the referral of the visit were analysed and compared with the
specialistic diagnoses. In our sample, dentists, relatives/friends and paediatricians were the major
source of the referrals, followed by family doctors and other facial specialists. In most cases, the
reasons for the referral were dental irregularities, but approximately 80% of dental irregularities were
associated with undiagnosed facial dysmorphism. Skeletal facial anomalies need an early diagnosis
to prevent the development of severe facial malformations that would require invasive and expensive
treatments. These findings reveal poor diagnostic skills regarding skeletal anomalies in dentists and
paediatricians and the need for better specific training
Salivary microRNA for diagnosis of cancer and systemic diseases: A systematic review
Background: The aberrant expression of microRNAs (miRNAs) has been associated with several diseases, including cancer, inflammatory, and autoimmune conditions. Interest in salivary miRNAs as non-invasive tools for the diagnosis of malignancies and systemic diseases is rapidly increasing. The present systematic review was developed for answering the question: \u201cAre salivary microRNAs reliable biomarkers for diagnosis of cancer and systemic diseases?\u201d Methods: The application of inclusion and exclusion criteria led to the selection of 11 papers. Critical appraisals and quality assessments of the selected studies were performed through the National Institute of Health \u201cStudy Quality Assessment Tool\u201d and the classification of the Oxford Center for Evidence-Based Medicine. Results: Seven studies reported statistically significant correlations between one or more salivary miRNAs and the investigated disease. The critical analysis allowed us to classify only two studies (18.2%) as having \u201cgood\u201d quality, the rest being scored as \u201cintermediate\u201d (8; 73%) and \u201cpoor\u201d (1; 9%). Evidence exists that salivary miR-940 and miR-3679-5p are reliable markers for pancreatic cancer and that miR140-5p and miR301a are promising molecules for the salivary diagnosis of gastric cancer. Conclusions: Further studies, possibly avoiding the risk of bias highlighted here, are necessary to consolidate these findings and to identify new reliable salivary biomarkers
Pre- and Postsurgical Orthodontics in Patients with Moebius Syndrome
The authors report a combined orthodontic-surgical correction of an adult patient’s malocclusion affected by Moebius Syndrome (MS). The treatment was conducted at the Dentistry Unit and the Maxillofacial Surgery Unit of the University Hospital of Parma. Treatment of malocclusion was performed after the correction of facial mimic mobility with smile surgery. The postoperative stability and orthodontic results were good and the correction of the morphological problems related to the syndrome was very satisfactory
Biological Role and Clinical Implications of microRNAs in BRCA Mutation Carriers
Women with pathogenic germline mutations in BRCA1 and BRCA2 genes have an increased risk to develop breast and ovarian cancer. There is, however, a high interpersonal variability in the modality and timing of tumor onset in those subjects, thus suggesting a potential role of other individual’s genetic, epigenetic, and environmental risk factors in modulating the penetrance of BRCA mutations. MicroRNAs (miRNAs) are small noncoding RNAs that can modulate the expression of several genes involved in cancer initiation and progression. MiRNAs are dysregulated at all stages of breast cancer and although they are accessible and evaluable, a standardized method for miRNA assessment is needed to ensure comparable data analysis and accuracy of results. The aim of this review was to highlight the role of miRNAs as potential biological markers for BRCA mutation carriers. In particular, biological and clinical implications of a link between lifestyle and nutritional modifiable factors, miRNA expression and germline BRCA1 and BRCA2 mutations are discussed with the knowledge of the best available scientific evidence
