To explore the prevalence of temporomandibular disorders (TMD) in patients affected by multiple sclerosis (MS) and whether there is a correlation between TMD prevalence and MS severity.PubMed, Web of Science, and Lilacs were systematically searched until July 30 2022, to identify studies presenting patients affected by MS and whether there is a correlation between TMD prevalence and MS severity.Out of 292 papers, 8 studies were included with 1312 study participants. Among the 8 studies, 5 had a control group; 5 used the RDC/TMD criteria, 1 used the NOT-S instrument, and 2 did not define a standardized method to define TMD symptoms. Meta-analysis revealed that the MS group had a higher rate than the control group, showing an association between MS and TMD (RR 2.10; 95% CI: 1.21-3.65).These findings show an association between TMD and MS.Australian Longitudinal Study of MS (AMSLS); Computed Tomography (CT); Community Periodontal Index of Treatment Needs (CPITN); Central Nervous System (CNS); Decayed, Missing, and Filled (DMF); Decayed, Missing, or Filled Teeth Index (DMFT); Expanded Disability Status Scale (EDSS); European Academy of Craniomandibular Disorders (EACD); Healthy Controls (HC); International Prospective Register of Systematic Reviews (PROSPERO); Multiple Sclerosis (MS); Nordic Orofacial Test-Screening (NOT-S); Participants, model of Intervention, Comparison and Outcome (PICO); Preferred Reporting Items for Systematic Reviews (PRISMA); Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD); Temporomandibular Joint (TMJ); Temporomandibular Disorders (TMD); World Health Organization (WHO).

Simple Summary Prognostic models to choose the right treatment schedule are needed in order to translate into practice a personalized approach. None of these models have been still entered into the clinical practice for what concern oral squamous cell carcinoma (OSCC). In this manuscript we performed a systematic review and subsequent quality assessment of already development prognostic model for OSCC with the aim to take stock of the situation on their possible clinical use. Abstract (1) Background: An accurate prediction of cancer survival is very important for counseling, treatment planning, follow-up, and postoperative risk assessment in patients with Oral Squamous Cell Carcinoma (OSCC). There has been an increased interest in the development of clinical prognostic models and nomograms which are their graphic representation. The study aimed to revise the prognostic performance of clinical-pathological prognostic models with internal validation for OSCC. (2) Methods: This systematic review was performed according to the Cochrane Handbook for Diagnostic Test Accuracy Reviews chapter on searching, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, and the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). (3) Results: Six studies evaluating overall survival in patients with OSCC were identified. All studies performed internal validation, while only four models were externally validated. (4) Conclusions: Based on the results of this systematic review, it is possible to state that it is necessary to carry out internal validation and shrinkage to correct overfitting and provide an adequate performance for optimism. Moreover, calibration, discrimination and nonlinearity of continuous predictors should always be examined. To reduce the risk of bias the study design used should be prospective and imputation techniques should always be applied to handle missing data. In addition, the complete equation of the prognostic model must be reported to allow updating, external validation in a new context and the subsequent evaluation of the impact on health outcomes and on the cost-effectiveness of care.

Ectopic lower third molar is an uncommon condition, and its etiology remains unclear. The main approach used for its surgical removal is the intraoral one, but there are cases in which this may not be the best option. When the lower third molar is located below the lower alveolar canal or when it is close to the lower edge of the jaw, the most recommended approach is the extraoral one. The critical issues related to the extraoral approach are the possibility of damaging anatomical structures such as marginal mandibular branch of the facial nerve (craniofacial nerve VII), facial artery and vein, and submental artery. This complication can occur during incision and dissection of the superficial layers or during osteotomy with rotating instruments.This paper reports a case of extraction of ectopic lower third molar using a minimally invasive extraoral approach combined with piezoelectric surgery in order to prevent intraoperative injury of anatomical structures.

The aim of this trial was to study the concentration of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), selenium (Se), cobalt (Co) and iodine (I) in milk and blood serum of lactating donkeys, taking into account the effects of lactation stage and dietary supplementation with trace elements. During a 3-month period, 16 clinically healthy lactating donkeys (Martina-Franca-derived population), randomly divided into two homogeneous groups (control (CTL) and trace elements (TE)), were used to provide milk and blood samples at 2-week intervals. Donkeys in both groups had continuous access to meadow hay and were fed 2.5 kg of mixed feed daily, divided into two meals. The mixed feed for the TE group had the same ingredients as the CTL, but was supplemented with a commercial premix providing 163 mg Zn, 185 mg Fe, 36 mg Cu, 216 mg Mn, 0.67 mg Se, 2.78 mg Co and 3.20 mg I/kg mixed feed. The concentrations of Zn, Fe, Cu, Mn, Se, Co and I were measured in feeds, milk and blood serum by inductively coupled plasma-MS. Data were processed by ANOVA for repeated measures. The milk concentrations of all the investigated elements were not significantly affected by the dietary supplementation with TE. Serum concentrations of Zn, Fe, Cu Mn and Se were not affected by dietary treatment, but TE-supplemented donkeys showed significantly higher concentrations of serum Co (1.34 v. 0.69 μg/l) and I (24.42 v. 21.43 μg/l) than unsupplemented donkeys. The effect of lactation stage was significant for all the investigated elements in milk and blood serum, except for serum manganese. A clear negative trend during lactation was observed for milk Cu and Se concentrations (-38%), whereas that of Mn tended to increase. The serum Cu concentration was generally constant and that of Co tended to increase. If compared with data reported in the literature for human milk, donkey milk showed similarities for Zn, Mn, Co and I. Furthermore, this study indicated that, in the current experimental conditions, the mineral profile of donkey milk was not dependent on dietary TE supply.

The aim of this trial was to study the concentration of Ti, V, As, Rb, Sr, Mo, Cd, Cs, and Pb in donkey milk and blood serum. One hundred twelve individual milk and blood serum samples were collected from 16 lactating donkeys (Martina-Franca-derived population; 6 to 12 yr old; 3 to 7 parities; average live weight 205.4kg; 32 to 58 d after foaling at the beginning of the trial) during a 3-mo-long experiment. The samples were analyzed for the aforementioned elements by inductively coupled plasma-mass spectrometry. Feedstuff and drinking water were also analyzed for the investigated elements. Data were processed by ANOVA for repeated measures. Average milk concentrations (±SD) of Ti, Rb, Sr, Mo, Cs, and Pb were 77.3 (±7.7), 339.1 (±82.1), 881.7 (±270.4), 4.5 (±1.6), 0.49 (±0.09), and 3.2 (±2.7) μg/L, respectively. More than 80% of samples were below the limit of detection for V, As, and Cd in milk and for Cd, and Pb in blood serum. The lower bound calculated for milk V, As, and Cd was 0.03μg/L for the 3 elements, the upper bound was calculated at 0.23, 0.10, and 0.31μg/L and the maximum value was observed at 0.54, 0.15, and 0.51μg/L, respectively. The average milk concentrations of Ti, Rb, Sr, Mo, and Cs were 600, 458, 346, 16, and 294%, respectively, than those of blood serum. Yet, Cs concentrations were in the same order of magnitude in milk and serum. Moderate to strong positive and significant correlation coefficients were observed between milk and blood serum concentrations for Ti, Rb, Sr, and Cs. The effect of the stage of lactation was significant for all the investigated elements in milk and blood serum, but most of the elements showed only small changes or inconsistent trends, and only the concentrations of Rb and Sr showed decreasing trends both in milk and blood serum. The relationship between milk and blood serum element concentrations indicates that the mammary gland plays a role in determining the milk concentrations of Mo, Ti, Rb, Sr, Mo, and Cs. In the current experimental conditions, in agreement with the low levels in drinking water and feedstuff, donkey milk concentration of potentially toxic elements was very low and did not raise health concerns for human consumption.

The aim of this trial was to study the content of calcium, phosphorus, potassium, sodium and magnesium in donkey milk. Individual milk samples obtained from 16 lactating jennies during a 3 month experiment were analyzed for Ca, P, K, Na and Mg by inductively coupled plasma-mass spectrometry. Average milk concentrations of Ca, P, K, Na and Mg were 807.09 mg L −1 , 638.42 mg L −1 , 746.61 mg L −1 , 140.94 mg L −1 , 81.69 mg L −1 , respectively. The Ca/P and Na/K ratios averaged 1.26 and 0.19, respectively. The concentration of the studied minerals was affected by the stage of lactation showing a decreasing trend for Ca, P and Mg. The correlation coefficients among all studied minerals were positive and significant except between Ca and Na. Results indicated that generally the concentration of macro elements in donkey milk is lower compared with milk from conventional dairy species and higher than human milk.

In the recent years the interest around donkey’s milk had a marked increase since it has been demonstrated that this milk can be used for feeding of infants affected by dairy cow’s milk protein intolerance (Businco et al., 2000; Iacono et al., 1992).

Cytidine deaminase (CDA) purified from human placenta revealed the presence of five isoenzymatic forms that differ only in their isoelectric point. Since human cytidine deaminase exists in two variants (CDA 1 and CDA 2) with a non-conservative amino acid substitution at codon 27, in this work we demonstrate that these two variants may combine together in vitro, giving five CDA isoforms as observed in vivo from human placenta. For this purpose, each of the two forms of CDA was purified close to homogeneity and dissociated into monomers in the presence of a small amount of sodium dodecyl sulfate as a dissociating agent. The monomers were mixed together and subjected to anion-exchange chromatography and to chromatofocusing analysis in order to visualize the formation of the five isoforms. Furthermore, for both CDA 1 and CDA 2 some substrates and inhibitors of CDA were assayed, with the aim of demonstrating different kinetic behavior between the two natural variants.
