Background: Recombinant human thyrotropin (rhTSH) is now currently used for the follow-up of patients with differentiated thyroid carcinoma (DTC) after total thyroid ablation. Side effects after rhTSH could involve the autonomic system and TSH receptors are possibly expressed in the heart and coronary arteries. Methods:Heart rate variability (HRV), studied by power spectral analysis of low (LF) and high frequency (HF) powers, blood pressure (BP) and their responses to orthostatism were investigated before and 3, 6, 9 days after the first of two administrations of rhTSH on alternate days in 11 patients on chronic l-thyroxine (l-T4) suppressive therapy for DTC and in 31 healthy controls. Results: A transient asymptomatic decrease in systolic and mean BP was observed during the rhTSH test, but rhTSH did not modify sympathovagal control of HRV and the lying to standing responses. Decreased LF power and LF/(LF + HF) and LF/HF ratios in DTC patients versus healthy controls indicated a sympathetic failure ascribed to the TSH-suppressive therapy with l-T4 rather than to direct effects of rhTSH. Conclusions: These findings allowed us to confirm the cardiovascular safety of rhTSH and the absence of its effects on sympathovagal control of HRV when used in the follow-up of patients with normal heart function after thyroid ablation for DTC.

Objectives: To evaluate the diagnostic performance of ClinCheck, Dolphin Imaging orthodontic software, and 3D Slicer for the analysis of Bolton discrepancy (BD)., Materials and Methods: Fifty-five pairs of early-stage digital models of patients treated with Invisalign were printed to measure the BD by manual method with a digital caliper (gold standard). The discrepancy values calculated by ClinCheck were obtained. In addition, the sample STL files were measured using Dolphin Imaging and 3D Slicer software to obtain BD values. To assess reliability, precision, and accuracy of the methods, intraclass correlation coefficients (ICCs), Dahlberg's formula, paired t-tests, and the Bland-Altman method were used, respectively. Repeated-measures analysis of variance with Bonferroni post hoc test was used to assess the difference between groups., Results: The three methods showed reliable measurements (ICC ≥ 0.7), with the values of anterior Bolton slightly higher than overall Bolton. Measurements for the anterior Bolton showed higher precision (Dahlberg's formula 0.65, 0.70, and 0.55) than those for the overall Bolton. For anterior Bolton, only the measurements obtained by ClinCheck and Dolphin Imaging were accurate (P > .05, no proportion bias), while for overall Bolton, all groups had a significant difference. The Bland-Altman plots demonstrated no consistency for anterior Bolton measurements when 3D Slicer was used and for the overall Bolton., Conclusions: ClinCheck and Dolphin Imaging showed accuracy to quantify anterior BD. For the overall Bolton measurements, ClinCheck showed a statistical difference from the manual assessment but without relevant clinical significance., (© 0000 by The EH Angle Education and Research Foundation, Inc.)

Introduction: In digital dentistry, virtual attachment removal (VAR) optimizes clear aligner therapy by enhancing efficiency for refinements and enabling prefabricated retainer production through the removal of attachments from a digital scan before the clinical removal of clear aligner attachments. This prospective clinical study aimed to evaluate the accuracy of VAR in the maxillary arch., Methods: A total of 110 teeth were analyzed from a sample of 54 maxillary scans from 25 subjects. Models with attachments were virtually debonded using Meshmixer (Autodesk, San Rafael, Calif) and superimposed over the control group in MeshLab. Vector Analysis Module (Canfield Scientific, Fairfield, NJ) was used to calculate and analyze 3-dimensional Euclidean distances on the buccal surfaces between the superimposed models. Statistical analysis was performed using SPSS (version 23.0, IBM, Armonk, NY). The Shapiro-Wilkes (α = 0.05) test determined a nonnormal distribution of results. The Kruskal-Wallis (α = 0.05) was used to determine differences between different tooth types and the number of attachments., Results: The VAR protocol showed no statistical differences in the root mean square between different tooth segments with an overall tendency for inadequate attachment removal. No difference between the groups was found regarding the number of attachments when used as a main factor., Conclusions: The VAR technique is precise enough for the fabrication of retainers from printed dental models in a clinical setting and is not affected by the number of attachments on the tooth., (Copyright © 2024 American Association of Orthodontists.

Introduction: This study aimed to quantify the outcomes of adolescent patients with Class II malocclusion treated with the Carriere Motion 3D Appliance (CMA) combined with full fixed appliances., Methods: Cone-beam computed tomography scans of 22 patients were available before orthodontic treatment (T1), at removal of the CMA (T2), and posttreatment (T3). The average age of the patients was 13.5 ± 1.6 years at T1, 14.1 ± 0.2 years at T2, and 15.6 ± 0.5 years at T3. The 3-dimensional image analysis procedures were performed using ITK-SNAP (version 3.6.0; www.itksnap.org, Hatfield, Pa) and SlicerCMF (version 4.11.0; http://www.slicer.org, Cambridge, Mass); skeletal and dentoalveolar changes relative to cranial base, maxillary, and mandibular regional superimpositions were evaluated., Results: Changes were analyzed with 1 sample t tests using the mean differences during the CMA phase (T1 to T2) and total treatment time (T1 to T3). Significant skeletal changes included a slight reduction of ANB from T1 to T3, mandibular growth (Co-Gn increment of 1.2 mm and 3.3 mm from T1 to T2 and T1 to T3, respectively), inferior displacement of point A, and anterior and inferior displacement of point B. The mandibular plane did not change significantly during treatment. During the CMA treatment, posterior tipping and distal rotation of the maxillary molars, tip back and inferior displacement of the maxillary canines, significant mesial rotation, and superior displacement of the mandibular molars were observed. These movements rebounded during the full fixed appliance phase except for the molar and canine vertical displacements. Clinically significant dental changes during treatment included a reduction in overjet and overbite, Class II correction of the molar and canine relationship, and proclination of the mandibular incisors., Conclusions: The CMA is an effective treatment modality for Class II correction in growing patients because of a combination of mesial movement of the mandibular molar, distal rotation of the maxillary molar, and anterior displacement of the mandible., (Copyright © 2023 American Association of Orthodontists.

Background: Malnutrition, in patients with solid tumors, is associated with a worse clinical outcome and about 40% of patients affected by head and neck cancers (HNC) are malnourished at the time of cancer diagnosis. We investigated the potential benefit of a standardized immunonutritional protocol (INP) to patients with HNC receiving major ablative surgery., Methods: An observational study was conducted enrolling 199 patients: 50 treated with the INP and 149 with standard enteral nutrition. Complication rates, need for medications, and costs were considered as outcomes., Results: INP played a protective role in development of major surgical complications (OR 0.23, p = 0.023), albumin administration (RR 0.38, p = 0.018), and antibiotic duration (p < 0.001) and is cost-effective in patients with moderate or severe malnutrition (-6083€ and -11 988€, p < 0.05)., Conclusions: Our study supports the utility of INP, and accurate nutritional screening can help to identify malnourished patients who would receive the most benefits from this protocol., (© 2022 Wiley Periodicals LLC.)

Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. In women with genital infection, the virus can be transmitted by sex to the oral cavity of their partners and then to their own oral cavity. The aim of the present study was to establish the prevalence of cervical/anal/oral HPV infection in women attending the Dermatology Unit of the Policlinico San Martino of Genoa, the regional reference hospital in Liguria, Italy., Methods: Between January 2016 and December 2018, the female patients attending the STI center (cases) and those requiring a full body skin examination for skin cancer screening ("supposed" healthy population: controls) were recruited. Cervical/anal/oral samples were collected with ThinPrep liquid based cytology preparation system: polymerase chain reaction for HPV and cytological evaluation were performed. Overall, 85 cases and 31 controls were recruited., Results: Cervical HPV infection was detected in 60% of the cases and 48% of the controls; anal HPV infection in 44% of the cases and 26% of the controls. Cervical and anal HPV infection resulted associated, especially in the control group. Moreover, 32% of the cases and 29% of the controls proved HPV positive in the oral cavity. In the cases of our series, prevalence of cervical, anal and oral HPV infection was higher compared with the controls., Conclusions: The high prevalence of anal-oral infections and the frequent association between anal and cervical infections, provide reason to suggest HPV screening also in the anal and oral regions, which may represent HPV reservoirs and grounds for cancer development., (©2022 Pacini Editore SRL, Pisa, Italy.)

Background: Sexually transmitted infections (STIs) may impact on the patient's physical, psychological and sexual health and negatively influence their Quality of Life (QOL). Studies on this topic are scarce. This study aimed to assess the impact of STIs different from HIV on QOL, mood and sexual functioning in the patients attending our STIs center in comparison with patients affected by chronic inflammatory bowel diseases (IBD)., Methods: An anonymous questionnaire was provided. It included 3 validated questionnaires: the European Quality of Life 5 dimensions 5 levels; the Beck Depression Inventory-II for depressive symptoms; the Changes in Sexual Functioning Questionnaire (CSFQ) for sexual functioning., Results: Seventy-three STIs patients and 51 IBD patients participated in the study. The mean EQ-5D-5L questionnaire scores were 86.72 in STIs and 89.21 in IBD patients, without statistically significant difference between the two groups. Symptoms of depression were more common and severe in STIs patients compared to IBD patients. Sexual functioning was slightly worse in STIs patients than in IBD patients., Conclusions: This is one the very few studies focused on the impact of STIs on patient's physical, psychological and sexual health. Physicians dealing with STIs should consider the possible psychological consequences of the disease.

The Coronavirus-19 (COVID-19) pandemic has many psychological consequences for the population, ranging from anxious-depressive symptoms and insomnia to complex post-traumatic syndromes. This study aimed to evaluate the impact of the Covid-19 pandemic on the mental well-being of healthcare workers, focusing on the association between hopelessness, death anxiety, and post-traumatic symptomatology. Eight hundred forty-two healthcare workers were recruited between 21 March 2020 and 15 May 2020. A specific questionnaire was administered to assess socio-demographic and clinical characteristics, together with psychometric scales: Beck Hopelessness Scale, Death Anxiety Scale (DAS), and Davidson Trauma Scale (DTS). Respondents with hopelessness scored higher in the DAS and DTS than respondents without hopelessness. Furthermore, death anxiety was identified as a potential mediator of the significant association between hopelessness and post-traumatic symptomatology. The impact of death anxiety should be recognized in vulnerable populations, such as frontline healthcare workers. Therefore, pharmacological and non-pharmacological strategies could be useful to attenuate the negative psychological consequences and reduce the burden worldwide.

Human papillomavirus (HPV) is a well-established carcinogenic agent. This study aimed to assess prevalence and persistence rate of genital HPV infection in sexually transmitted infections (STIs) patients and healthy subjects. The risk factors influencing the persistence of genital HPV infection were also investigated. The samples were collected with the ThinPrep liquid-based cytology system. Among the HPV-positive patients, those consenting were retested after 12 months. Overall, 145/292 subjects proved HPV positive with a higher prevalence (51%) in STI than in healthy population (43%). The persistence of genital HPV infection was statistically associated with female gender, HR-HPV infection, smoking, and Ureaplasma parvum infection.

Abstract: Distraction osteogenesis (DO) is a highly effective technique for correction of severe maxillary hypoplasia, especially in patients with orofacial clefts and craniofacial syndromes. The purpose of this retrospective, longitudinal study was to assess long-term airway alterations after maxillary advancement using a rigid external distraction system (RED) in non growing cleft patients. Fifteen cleft patients (8 males and 7 females) aged from 14 to 25 years were included in this study. All of them were treated with a rigid external distraction system for maxillary advancement after a high Le Fort I osteotomy. To analyse airway changes lateral cephalograms were obteined before distraction (T0), immediately after distraction (T1) and 1 to 3 years and 3 months after distraction (T2). All the measurements were describled by means of median, minimum and maximum. In order to evaluate differences between each time interval, a Wilcoxon test associated to a Delta Cliff test was used to evaluate the effect size (level of significance adopted was 5%). A significant maxillary advancement and increased upper airway antero-posterior dimensions were observed after the distraction osteogeness process, as demonstrated by the difference between T1 and T0. No significant relapse at T2 was found. Lower airway and the airway at tip of uvula region did not display significant alterations. A significant maxillary advancement and increased antero-posterior upper airway dimension was measured immediately after maxillary distraction with rigid external distraction in non growing cleft patients. The findings were stable three years after distraction., Competing Interests: AAF reports reciept of royalties from KLS Martin; the remaining authors report no conflicts of interest., (Copyright © 2020 by Mutaz B.

Since 2013 in Emilia-Romagna, Italy, surveillance information generated in the public health and in the animal health sectors has been shared and used to guide public health interventions to mitigate the risk of West Nile virus (WNV) transmission via blood transfusion. The objective of the current study was to identify and estimate the costs and benefits associated with this One Health surveillance approach, and to compare it to an approach that does not integrate animal health information in blood donations safety policy (uni-sectoral scenario). Costs of human, animal, and entomological surveillance, sharing of information, and triggered interventions were estimated. Benefits were quantified as the averted costs of potential human cases of WNV neuroinvasive disease associated to infected blood transfusion. In the 2009-2015 period, the One Health approach was estimated to represent a cost saving of €160,921 compared to the uni-sectoral scenario. Blood donation screening was the main cost for both scenarios. The One Health approach further allowed savings of €1.21 million in terms of avoided tests on blood units. Benefits of the One Health approach due to short-term costs of hospitalization and compensation for transfusion-associated disease potentially avoided, were estimated to range from €0 to €2.98 million according to the probability of developing WNV neuroinvasive disease after receiving an infected blood transfusion.

Background: Bloodstream infections (BSI) due to carbapenem-resistant (C-R) Klebsiella pneumoniae (Kp) are of global concern from both clinical and public health standpoints. This retrospective study aimed to describe C-R Kp BSI epidemiology in a large teaching hospital in northern Italy., Methods: Between 1 January 2007 and 31 December 2014, annual incidences both of C-R Kp BSI and of carbapenem-susceptible (C-S) Kp BSI were calculated as the number of events per 10,000 patient-days. A Chi square test for linear trend was used to assess the change in the incidence of C-R Kp BSI and C-S Kp BSI over the study period. Crude 30-day mortality rates were provided both for C-R Kp BSI and for C-S Kp BSI., Results: From 2007 to 2014, we observed 511 episodes of Kp BSI, 349 of which were caused by C-R Kp (68.3 %). The incidence of C-R Kp BSI considerably increased from 0.04/10,000 patient-days in 2007 to 1.77/10,000 patient-days in 2014 (Chi square for trend p < 0.001). The highest incidence of C-R Kp BSI was observed in intensive care units (ICUs), with a peak of 22.01 C-R Kp BSI/10,000 patient-days in 2012. A less marked but significant increase of C-S Kp BSI was also observed (Chi square for trend p = 0.004). Crude 30-day mortality was 36.1 % in patients with C-R Kp BSI and 23.5 % in those with C-S Kp BSI., Conclusions: During the study period, we observed a dramatic increase in the incidence of C-R Kp BSI in our hospital. More concerted infection-control efforts are needed to contain this alarming C-R Kp diffusion.

The goal of Occupational Medicine and Hygiene is that of ensuring safety, health and well-being at workplaces, mainly assessing and preventing existing occupational risks. Scientific research in this field can provide useful arguments and further evidence upon which effective, efficient and sustainable policies and preventive measures have to be chosen and applied by the occupational physician in work-life. This paper summarizes four original studies, conducted in different professional settings across Italy, focusing on critical items, such as stress and violence, biological risks and sleep hygiene. The knowledge obtained can be useful to orientate proper preventive programs aimed at improving workplace health., (© Copyright by Pacini Editore SpA, Pisa, Italy.)
