Abstract
Radial nerve entrapment is an uncommon diagnosis. The entrapment can occur at any location within the course of the nerve distribution, but the most frequent location of entrapment occurs around the elbow and involves the posterior interosseous nerve. Several potential sites of radial nerve entrapment around the elbow are identified: the capsular tissue of the radiocapitellar joint; hypertrophic crossing branches of leash of henry; the leading proximal tendinous and medial edge of extensor carpi radialis brevis; the arcade of Frohse and distal border of the supinator between its two heads. The arcade of Frohse is the most common site of compression. The aim of this manuscript is to describe the common surgical methods to approach the radial nerve entrapments around the elbow and define the preferred surgical approach based on the site of compression.

Abstract
BACKGROUND Limited information exists on postoperative hypocortisolism and hypothalamus-pituitary-adrenal axis recovery in patients with adrenal incidentaloma following unilateral adrenalectomy. We evaluated frequency of postoperative hypocortisolism and predictors for recovery in non-aldosterone-producing adrenocortical adenoma patients after unilateral adrenalectomy. METHODS A retrospective analysis of 32 adrenal incidentaloma patients originally included in the ITACA trial (NCT04127552) with confirmed non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy from September 2019 to April 2023 was conducted. Preoperative assessments included adrenal MRI, anthropometrics, evaluation of comorbidities, adrenal function assessed via ACTH, urinary free cortisol, and 1 mg dexamethasone suppression test. ACTH and serum cortisol or Short Synacthen test were performed within 6 days, 6 weeks, 6 months, and a year after surgery. RESULTS Six days postoperative, 18.8% of patients had normal adrenal function. Among those with postoperative hypocortisolism, 53.8% recovered by 6 weeks. Patients with earlier adrenal recovery (6 weeks) had lower preoperative 1 mg dexamethasone suppression test (median 1 mg dexamethasone suppression test 76.2 [61.8-111.0] nmol/L vs 260.0 [113.0-288.5] nmol/L, p < 0.001). Univariate analysis showed preoperative 1 mg dexamethasone suppression test negatively related with baseline ACTH levels (r = - 0.376; p = 0.041) and negatively associated with the 6-week baseline (r = - 0.395, p = 0.034) and 30-min cortisol levels during Short Synacthen test (r = - 0.534, p = 0.023). Logistic regression analysis demonstrated preoperative 1 mg dexamethasone suppression test as the only biochemical predictor for 6-week adrenal recovery: ROC curve identified a 1 mg dexamethasone suppression test threshold of 131 nmol/L predicting 6-week recovery with 89.5% sensitivity and 72.7% specificity (AUC 0.87; 95% CI 66.9-98.7, p < 0.001). Other preoperative assessments (tumor size, ACTH levels and anthropometrics) were not associated with postoperative hypothalamus-pituitary-adrenal axis function, but the presence of diabetes was associated with a lower probability of recovery (OR = 24.55, p = 0.036). ACTH levels increased postoperatively in all patients but did not predict hypothalamus-pituitary-adrenal axis recovery. CONCLUSIONS The preoperative 1 mg dexamethasone suppression test cortisol value and presence of diabetes are the only relevant predictor of hypothalamus-pituitary-adrenal axis recovery in patients with non-aldosterone- producing adrenocortical adenoma undergoing surgery, regardless other clinical and biochemical variables. Notably, pre- and postoperative ACTH levels did not predict hypothalamus-pituitary-adrenal axis recovery. These findings point towards the potential for saving resources by optimizing their allocation during follow-up assessments for patients with non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy.

Abstract
Background We reviewed the shoulder arthroplasty (SA) literature to correlate citations, methodological characteristics and quality of most-cited articles in this field. We hypothesized that a greater number of citations would be found for high-quality clinical studies. Methods We searched the Web of Knowledge database for the 50 most-cited articles about SA and collected author name, publication year, country of origin, journal, article type, level of evidence (LoE), subject of paper, type of arthroplasty and metrics (number of citations and citation rate). Coleman Methodology Score (CMS) was computed for clinical articles. Statistical analysis of variance and correlation coefficients were used to investigate the relationship between different variables. Results Out of the selected 50 studies on SA, 26% were nonclinical. There were 15,393 citations overall (mean 307.8), with a mean 19.5 citations per year (range 48.3-6.7). Thirty or 60% of all articles were LoE IV. All studies were published between 1984 and 2011 in 8 journals. Reverse SA (RSA) was the most common subject (36% of studies). The United States was the country responsible for most contributions (50% of studies). CMS ranged from 81 to 38 (mean 59.6). RSA received the highest number of citations (P < .001), independently from country of origin (P = .137) and LoE (P = .723). CMS correlated with citation rate (r = 0.397; P = .013) and publication year (tau = 0.397; P = .013), but not with LoE (P = .204). Conclusion In SA literature, citation rate positively correlates with methodological quality of a study, independently from publication country and LoE. Among most-cited papers, RSA is the most common standalone subject.

Abstract
PURPOSE The management of isolated SLAP lesions is still debated especially in athletes. Aims of the study were: 1. to analyse our algorithm to treat SLAP lesions starting from the selection of patients for surgery and 2. to correlate the familiarity for diabetes and hypothyroid disorders with post-operative results. METHODS Seventy-eight patients with isolated SLAP lesion were arthroscopically treated using knotless anchors and microfractures. All patients had a pre-operative and post-operative clinical examination according to Walch-Duplay, Constant, Rowe and Dash scores and interviewed for familiarity to diabetes and hypothyroid disorders. RESULTS About 68.8% of patients solved pain with rehabilitation. About 29% of patients returned to the sports activities. About 32% of patients were no responder to physiotherapy and were arthroscopically treated. About 53.9% of patients responded excellent, 34.7% good, 3.8% medium and 7.6% poor results according to Walch-Duplay score. The Constant score increased from 64 to 95, the Rowe score from 48 to 96. The outcomes were significantly worse in patients with familiarity for diabetes. CONCLUSIONS Microfractures and knotless anchor give long-term good results for the treatment of SLAP lesions in athletes. The familiarity for diabetes is an important risk factor that can lead to decreased outcomes.

Abstract
Background The aim of this study was to investigate the impact of computed tomography on the reliability of Boileau classification for proximal humerus fracture sequelae. Methods A prospective study was designed using STARD guidelines. We included all patients diagnosed with proximal humerus fracture sequelae who underwent surgery at our institution between 2017 and 2021. Preoperative radiographs and computed tomography scans were reviewed by three independent observers. Intra- and inter-observer reliability and the diagnostic accuracy of radiographs and computed tomography scans in detecting chronic dislocation, nonunion, and severe greater tuberosity dislocation were assessed. Results Fifty-two patients were included in the study. The overall interobserver agreement was low on both radiographs and computed tomography scans. On radiographic images, we found a sensitivity of 97%, 88.9%, and 84.1%, and a specificity of 58.3%, 40%, and 53.3% to detect chronic dislocation, nonunion, and greater tuberosity dislocation, respectively. On computed tomography scans we reported a sensitivity of 100%, 96.8%, and 93.7%, and a specificity of 91.7%, 86.7%, and 93.3% to detect chronic dislocation, nonunion, and greater tuberosity dislocation, respectively. Discussion Computed tomography scan was more specific than radiographs in the assessment of proximal humerus fracture sequelae. However, even using a three-dimensional evaluation of the deformity, the Boileau classification had a poor interobserver reliability. Level of Evidence I. Testing previously developed diagnostic criteria in a consecutive series of patients and a universally applied "gold standard."

Abstract
BACKGROUND The gold standard anesthesiologic procedure for urgent femur fracture surgery is Spinal Anesthesia. It is not always feasible because of patients' severe comorbidities and difficulties in optimizing drug therapy in the appropriate time frame such as discontinuation of anticoagulant drugs. The use of four peripheral nerve blocks (tetra-block) can be a winning weapon when all seems lost. CASE PRESENTATION We present, in this case series, three Caucasian adult femur fractures (an 83-year-old woman, a 73-year-old man, and a 68-year-old woman) with different and major comorbidities (cardiac or circulatory disorders on anticoagulants therapy that were not discontinued on time; breast cancer and others) underwent the same anesthesiologic approach in the urgent setting. Ultrasound peripheral nerve blocks, that is femoral, lateral femoral cutaneous, obturator, and sciatic with parasacral approach were successfully performed in all patients who underwent intramedullary nailing for intertrochanteric fracture. We evaluated the adequacy of the anesthesia plane, postoperative pain control with the VAS scale, and the incidence of postoperative side effects. CONCLUSIONS Four peripheral nerve blocks (Tetra-block) can be alternative anesthesiologic management in urgent settings, in patients where drug therapy cannot be optimized, as in antiplatelet and anticoagulant therapy.

Abstract
BACKGROUND It is unclear whether lateral soft tissue release (LSTR) is required as part of percutaneous hallux valgus (PHV) surgery. The primary aim of this systematic review was to assess whether LSTR reduces the risk of recurrence of hallux valgus deformity. The secondary aims were to assess if LSTR increases the risk of complications, improves the clinical outcome and leads to a greater radiographic correction. METHODS We performed a PRISMA-compliant PROSPERO-registered systematic review, pooling clinical papers reporting results after PHV surgery into two categories (PHV with (Group 1, G1) and without LSTR (Group 2, G2)) and comparing them. Data regarding the study design, demographics, the surgical procedure and the clinical and radiological outcome were extracted and compared. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS Sixteen studies were selected (G1:594 feet; G2:553 feet). The pooled proportion of recurrence at a minimum 21-month follow-up (2%, 95%CI 0-3 vs 2%, 95%CI 0-5; p = 0.70) did not differ in the two groups. Similarly, the pooled proportion of complications (27%, 95%CI 17-38 vs 25%, 95%CI 12-37; p = 0.79) was similar. The pre- (p = 0.23) and post-operative AOFAS scores (p = 0.16), the pre-(HVA: p = 0.23) (IMA: p = 0.94) and post-operative radiological angles (HVA: p = 0.47) (IMA: p = 0.2) and the methodological quality of studies (p = 0.2) did not differ either between G1 and G2. CONCLUSION There is no evidence that LSTR performed during percutaneous HV surgery reduces the risk of recurrence of the deformity at a mean 4-year follow-up nor improves the clinical and radiological outcome. LEVEL OF EVIDENCE Level IV systematic review of Level I to IV studies.

Abstract
OBJECTIVE High tibial valgus osteotomy (HTO) is a widely accepted procedure indicated for varus knee with symptomatic osteoarthritis of the medial compartment. However, there is a lack of studies evaluating long term results of this procedure. The primary aim of this study was to evaluate the long-term survival of opening wedge high tibial osteotomy (HTO) for isolated osteoarthritis in the medial compartment of the knee. The secondary objective was to identify independent predictors of conversion to total knee arthroplasty (TKA). METHODS This is a long term retrospective study of 296 cases of open wedge HTOs performed at a single center (level of evidence IV) between January 2005 and August 2015. Opening wedge medial HTO was always performed after diagnostic arthroscopy. Eighty-three percent of the population (233 patients, 247 procedures) was followed up at a mean 11.6 years (6-17) by telephone interview, to evaluate the possible conversion to TKA. Mean age at the index operation was 42.8 years (range 15-70) and most patients were male (70%). Associated procedures (e.g., platelet rich plasma supplementation, microfractures, meniscectomy, etc.) were carried out at the time of the HTO in 80 (32%) cases. Survival of HTO and its association with age, sex, body mass index, smoking habit, preoperative severity of varus deformity, cartilage status at surgery, and associated procedures were evaluated. Kaplan-Meier and Cox regression analyses were performed. RESULTS Thirty-three of the 247 HTOs (13.4%) were converted to knee replacement, with 86.6% of the original procedures surviving at a mean 12-year follow-up. Kaplan-Meier survival estimates at 17 years for HTO were 75.5% (95% confidence interval [CI] 66.7-84.3). There was significant difference (P < 0.001) in the 17-year survival rate between obese (55.5%; 95% CI 35.3-75.6) and non-obese (79.7%; 95% CI 70.1-89.2) patients. The determinants of conversion to knee arthroplasty detected at multivariate Cox regression analysis were body mass index, severity of cartilage degeneration in the medial compartment (Outerbridge grade), and age. CONCLUSION The long-term survival of open wedge HTO for osteoarthritis in the medial compartment of the knee is satisfactory. The risk of conversion to TKA is significantly increased in obese patients. Advanced age and severity of pre-existing cartilage damage may also contribute to the risk of conversion to TKA.

Abstract
Objectives This study aims to report our experience with Clostridium Histolyticum collagenase (CCH) to support the importance of its clinical use and assess its clinical efficacy, complications, and recurrences. Methods This prospective observational study of 66 patients with a 2-year follow-up. Patients with an extension lag major of 20° at the metacarpophalangeal joint (MPJ) and/or proximal interphalangeal joint (PIPJ) were included. We collected data on demographic and anamnestic details, MPJ and PIPJ contracture degrees, DASH score, complications, and recurrences. Results The mean pre-injection contracture was 34° for MPJ and 31° for PIPJ. At the 2-year follow-up, the mean contracture for the MPJ and PIPJ were respectively 3° and 14.5°. The mean DASH score decreased from 21.8 before injection to 10,4 after 2 years. The disease recurrence occurred in 34.8% of the patients, all with PIPJ contracture. The main complication was skin breakage (25.7%). Conclusion The CCH injections remain a consistent option in treating DD; withdrawal from the European market deprives surgeons and patients of low invasiveness and safe tool for treating DD. Level of evidence IV, Therapeutic study investigating treatment results, Case series .

Abstract
Programmed Death Ligand 1 (PD-L1) is crucial in regulating the immunological tolerance in non-small cell lung cancer (NSCLC). Alveolar macrophage (AM)-derived PD-L1 binds to its receptor, PD-1, on surveilling lymphocytes, leading to lymphocyte exhaustion. Increased PD-L1 expression is associated with cigarette smoke (CS)-exposure. However, the PD-L1 role in CS-associated lung diseases associated with NSCLC, such as chronic obstructive pulmonary disease (COPD), is still unclear. In two different cohorts of ever smokers with COPD or NSCLC, and ever and never smoker controls, we evaluated PD-L1 expression: (1) via cutting-edge digital spatial proteomic and transcriptomic profiling (Geomx) of formalin-fixed paraffin-embedded (FFPE) lung tissue sections (n = 19); and (2) via triple immunofluorescence staining of bronchoalveolar lavage (BAL) AMs (n = 83). PD-L1 mRNA expression was also quantified in BAL AMs exposed to CS extract. PD-L1 expression was increased in the bronchiolar wall, parenchyma, and vascular wall from mild-moderate (GOLD 1-2) COPD patients compared to severe-very severe (GOLD 3-4) COPD patients and controls. Within all the COPD patients, PD-L1 protein expression was associated with upregulation of genes involved in tumor progression and downregulation of oncosuppressive genes, and strongly directly correlated with the FEV1% predicted, indicating higher PD-L1 expression in the milder vs. more severe COPD stages. In bronchioles, PD-L1 levels were strongly directly correlated with the number of functionally active AMs. In BAL, we confirmed that AMs from patients with both GOLD 1-2 COPD and NSCLC had the highest and similar, PD-L1 expression levels versus all the other groups, independently from active cigarette smoking. Intriguingly, AMs from patients with more severe COPD had reduced AM PD-L1 expression compared to patients with mild COPD. Acute CS extract stimulation increased PD-L1 mRNA expression only in never-and not in ever-smoker AMs. Lungs from patients with mild COPD and NSCLC are characterized by a similar strong PD-L1 expression signature in bronchioles and functionally active AMs compared to patients with severe COPD and controls. Active smoking does not affect PD-L1 levels. These observations represent a new resource in understanding the innate immune mechanisms underlying the link between COPD and lung cancer onset and progression and pave the way to future studies focused on the mechanisms by which CS promotes tumorigenesis and COPD.

Abstract
PURPOSE To compare functional outcomes, complication rates, and survival in patients with intertrochanteric fracture treated with percutaneous compression plate (PCCP) or gamma nail (GN). METHODS A retrospective study of prospectively collected data of patients treated with PCCP or GN for AO/OTA 31.A1 or AO/OTA 31.A2 fractures was conducted. Sixty-eight consecutive patients treated with PCCP between 2018 and 2020 were enrolled and matched with 68 patients with comparable characteristics treated with GN. The activities of daily living (ADL) index and specific scales for walking ability and need for walking aids at 4 months and 1 year after fracture fixation were chosen as primary outcomes. Postoperative complications and one-year survival were recorded and compared between the two groups. RESULTS Walking ability and ADLs index decreased and the need for walking aids increased in both groups compared to the prefracture state at both follow-up intervals (p < 0.001), regardless of the treatment received. There was no difference between the two implants in the rate of implant-related complications. One-year survival rate was 78.9% (95% CI 67.0-86.9) and 82.4% (95% CI 71.0-89.5) in patients undergoing PCCP or GN, respectively, with no significant difference between the two groups. CONCLUSIONS Walking ability, ADLs, complication rate, and 1-year survival are not significantly different when patients undergoing PCCP or GN are compared. The choice of implant may not be decisive for the outcome of treatment of intertrochanteric fractures, provided that stable fixation is ensured.

Abstract
OBJECTIVE Although the two-stage technique is a validated strategy in periprosthetic joint infections, there is a lack of data on the patients' clinical outcomes after the spacer placement. This study aims at evaluating the quality of life, joint function, and pain in patients over 70 years affected by periprosthetic joint infection treated with a two-stage exchange using metal on polyethylene spacers. PATIENTS AND METHODS We conducted a follow-up study to evaluate the quality of life and functionality of consecutive patients over 70 years treated for PJI at our institution using a validated assessment set including the Western Ontario and Mac Master University (WOMAC) score, Knee Society Score (KSS), numerical rating scale (NRS). Knee Range of Movement (ROM) before and after the surgery was also analyzed. RESULTS Forty-five patients with a mean age of 76 ± 5.3 years were included. Coagulase-negative staphylococci were the most isolated microorganisms. In the preoperative study group, the WOMAC score was 48.4 ± 18.9, and the KSS objective and functional scores were 37.6 ± 17.3 and 27.6 ± 22.3, respectively. NRS was 7.3 ± 1.8. After three months of follow-up, we found better results than preoperative clinical evaluation. We retrieved similar results comparing our post-operative PROMS (WOMAC and KSS scores) with published thresholds for treatment success two months after primary total knee arthroplasty. The infection eradication rate was 87%. CONCLUSIONS The two-stage technique confirmed its efficacy in the treatment of PJI. Patients over 70 years who had undergone the first stage of the two-stage technique for PJI showed a good quality of life and knee function.

Abstract
Background Symptomatic proximal humeral fracture sequelae (PHFS) represent a surgical challenge due to the altered bone and soft tissue morphology. The purpose of this study was to report the outcome of Multiplanar Corrective Humeral Osteotomies (MCHOs) in combination with reverse total shoulder arthroplasty (rTSA) performed following a three-dimensional (3D) preoperative planning and using a 3D-printed patient-specific surgical instrumentation (PSI) in type 1C, 1D, and 4 PHFS. Methods In this prospective monocentric study, we enrolled patients affected by symptomatic PHFS type 1C, 1D, or 4 of Boileau's classification, treated between 2018 and 2019 with rTSA associated to MCHO and followed-up at 12 and 24 mo. The preoperative and postoperative Constant Score (CS), visual analog scale, and Disabilities of the Arm, Shoulder and Hand (DASH) score were recorded. All patients underwent a preoperative computed tomography, then a dedicated software was used to run a segmentation algorithm on computed tomography images. Metaphyseal bone cuts were virtually performed before surgery in all patients, and a 3D-printed PSI was used to reproduce the planned osteotomies in vivo. Results Twenty patients completed a 2-y follow-up. The mean (± standard deviation) CS, visual analog scale, and DASH values improve from 24.3 (± 8.8), 6.5 (± 1.3), 60.7 (± 9.6) preoperatively, to 67.7 (± 11.4), 1.6 (± 0.8), 24.1 (± 13.1) points after surgery, respectively. The minimally clinical important difference for CS and DASH score was achieved in 95% of patients. No major complication was observed. One patient showed an unexplained worsening of clinical scores between the 12 and the 24-mo follow-up, while in one patient bone resorption of the greater tuberosity was observed on radiographs at 2 y, with no clinical impact. Conclusion The combination of preoperative 3D planning and intraoperative use of 3D-printed PSI to perform MCHO as concurrent procedure in the context of rTSA in the treatment of Boileau type 1C, 1D, and 4 PHFS may lead to a satisfactory clinical outcome at 2 y of follow-up.

Abstract
Background The treatment of proximal humerus fracture complicated by bone fragility is still controversial. The aim of this study is to compare the Neer classification and the Control Volume severity grade for the accuracy in the selection of the type of treatment and for prognostic evaluation. Materials and methods We retrospectively collected the records of all patients admitted at the Emergency Department of our Institute, from 2013 to 2020, for a closed displaced proximal humerus fracture further investigated with a CT scan before treatment decision. We selected all patients with a minimum age of 65 years. The included fractures were retrospectively classified according to Neer, and Control Volume severity grade. The included patients were evaluated with Simple Shoulder Test (SST). A statistical analysis was performed to correlate the type of treatment and the clinical results to the Neer classification and the Control Volume severity grade. Results Sixty-four patients (80%), were available for the telephonically interview at a mean follow up of 4 years and were included. According to the Control Volume model, we identified fracture with a low, medium and high severity grade, in 23 (36%), 13 (20%), and, 28 (44%) cases, respectively. Fifteen patients (23,5%) were conservatively treated, whether fourty-nine patients (76,5%) were operated. We find a statistical correlation between control volume severity grade and type of treatment. No Therapeutic correlation was detected for the Neer classification. A statistical correlation between the severity grade and clinical outcome could be observed only for patients with the same type of treatment. Conclusions The use of Control Volume severity grade is associated with better therapeutic and prognostic informations in confront to the Neer classification.

Abstract
Background Osteoporosis is responsible for fragility fractures, which are associated with impaired quality of life (QoL) and disability. Objective The aim of the study was to evaluate the QoL in patients affected by osteoporosis and possible determinants. Methods One-hundred thirty-four subjects followed at the osteoprosis outpatient clinic at our institution completed the QUALEFFO-41 questionnaire for quality of life. All subjects had undergone bone densitometry measurement and the FRAX index, summarizing the risk of fragility fracture, was calculated for each of them. The QoL in these subjects and its possible determinants were investigated with univariate and multiple linear regression analysis. Results Subjects with osteoporosis had lower scores in the domains of physical and social function of the QUALEFFO questionnaire in comparison with subjects with normal bome mineral density. Main factors associated with impairment in QoL were high FRAX score and body mass index (BMI). Conclusion Physical and social function is reduced in osteoporotic subjects. High BMI and an increased risk of fragility fracture were main determinants of impairment in the QoL in this study.

Abstract
BACKGROUND Pyrocardan® (Wright Medical-Tornier) is a pyrocarbon implant proposed in the treatment of trapeziometacarpal joint (TMCJ) osteoarthritis. Our aim was to assess the clinical and radiographic results after Pyrocardan® arthroplasty at midterm follow-up. METHODS In this prospective monocentric study, we enrolled 119 patients treated with Pyrocardan® for TMCJ osteoarthritis and followed up at a minimum of four years. The clinical outcome was assessed through the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, the Visual Analog Score (VAS) for pain and the Kapandji score collected pre-operatively, at three, six and 12 months, then yearly. Hand radiographs were taken before surgery, at three months and every year. Complications and re-operations were also recorded. RESULTS The mean follow-up was 5.2 years (range, 4-9). DASH, VAS and Kapandji scores significantly improved at three (p < 0.001 in all cases) and six months (p < 0.001, p = 0.01 and p < 0.001, respectively), remaining stable over time. The dislocation and subluxation rates were 3.3% (4 cases) and 16.8% (20 patients), respectively. The two year, four year and seven year survivorship of the implant was 99%, 98% and 95%, respectively. CONCLUSION Pyrocardan® arthroplasty provides a satisfactory clinical and radiographic outcome for treating TMCJ osteoarthritis, with a 97% survival rate at four years. We advocate comparative studies with more common techniques (i.e., trapeziectomy) to verify its cost-effectiveness.

Abstract
Humeral stem prosthesis implantation in case of proximal humerus varus malunion (type 1D fracture sequelae) is often complicated by greater tuberosity fracture and by posterosuperior rotator cuff iatrogenic damage. Moreover, the varus malunited humeral head could lead to scapular impingement and reduce the range of motion. To address this problem, we introduced a new surgical procedure consisting in a proximal humerus osteotomy, planned with three-dimensional (3D) preoperative virtual surgery, and performed with patient-specific surgical guides, to correct humerus deformity before the implantation of the prosthetic humeral stem. A 3D evaluation of the deformity, based on the comparison to the healthy contralateral side or to anatomical standard values, is firstly performed. The metaphyseal osteotomy is then planned and virtually performed. To faithfully reproduce the planned correction, 3D printed surgical guides are prepared. Before the surgery, it is advisable to perform a simulation of the planned osteotomies to verify their real feasibility and to find any critical issues. Preliminary outcomes of this surgical technique are encouraging, but formal studies are warranted to validate its clinical utility and longevity of results.

Abstract
PURPOSE The classification of indeterminate cytopathology at thyroid fine-needle-aspiration (FNA) has been updated to reduce the number of unnecessary surgery; the 2014 Italian classification introduced the low-risk (TIR3A) and high-risk (TIR3B) subcategories. Aim of this study was to identify the ultrasonographic (US), clinical and cytological predictors of malignancy among TIR3B nodules from a single institution. METHODS A prospective observational study including 1844 patients who underwent thyroid FNA from June 2014 to January 2019. Ultrasonographic, clinical and cytological features were recorded. All TIR3B diagnoses were referred to surgery. According to final histology, patients were divided into thyroid cancer (TC) or benign nodules. Chi-square test, or Fisher exact test when appropriate, were used to compare groups and logistic regression analyses were used to determine independent predictors of malignancy. RESULTS Of 1844 FNAs, 96 (5.2%) were TIR3B. Histology report was available in 65. Among them, 25 (38.5%) were TC. Predictors of TC were nodule size < 20 mm [Odds Ratio (OR) = 5.88, 95% CI 1.91-18.11, p = 0.002], absence or weak intralesional flow [OR = 0.3, 95% CI 0.09-0.77, p = 0.015], microcalcifications [OR = 6.5, 95% CI 1.90-21.93, p = 0.003] at US; nuclear inclusions [OR = 25.3, 95% CI 1.34-476.07, p = 0.031] and chromatin clearing [OR = 3.7, 95% CI 1.27-10.99, p = 0.017] at cytopathology. Patients aged < 55 years had a significantly higher risk of TC [OR = 9.7, 95% CI 2.79-34.07, p < 0.001]. In multivariate analysis, age < 55 and nodule size < 20 mm resulted as independent risk factors. CONCLUSIONS Patients < 55 years receiving a diagnosis TIR3B on nodules < 20 mm, with microcalcifications, showing specific nuclear atypia at cytopathology are more likely to have TC. Combining US, cytological and clinical features could help determining which patients with a TIR3B diagnosis should be referred to surgery.

Abstract
PURPOSE Capoeira is a Brazilian martial art that requires extreme movements of the hip to perform jumps and kicks. This study evaluated a group of capoeira players to assess the prevalence of femoroacetabular impingement (FAI) in athletes practicing this martial art. METHODS Twenty-four experienced capoeira players (14 men, 10 women) underwent a diagnostic assessment, including clinical examination and standard radiographs of the pelvis and hips. The α-angle, head-neck offset, crossover sign, acetabular index, lateral centre-edge angle, and the Tönnis grade were assessed using the radiographs. Clinical relationships for any radiographic abnormalities indicating FAI were also evaluated. RESULTS Four subjects (17 %) reported pain in their hips. Forty-four hips (91.7 %) had at least one radiographic sign of CAM impingement, and 22 (45.8 %) had an α-angle of more than 60°. Eighteen hips (37.5 %) had at least one sign of pincer impingement and 16 (33.3 %) a positive crossover sign. Sixteen hips (33.3 %) had mixed impingement. There was a significant positive association between having an α-angle of more than 60° and the presence of groin pain (P = 0.002). A reduced femoral head-neck offset (P < 0.001) and an increased α-angle on the anteroposterior radiograph (P = 0.008) were independently associated with a higher Tönnis grade. CONCLUSION High prevalence of radiographic CAM-type FAI among these skilled capoeira players was found. In these subjects, a negative clinical correlation for an increased α-angle was also detected. Additional caution should be exercised whenever subjects with past or present hip pain engage in capoeira.

Abstract
Epidermoid cysts comprise less than 1% of intraspinal tumors. They can be congenital, frequently associated with other spinal malformations, or iatrogenic, resulting from the implantation of epidermal cells within the spinal canal during the execution of a variety of procedures such as spinal puncture. At MR imaging epidermoid tumors can mimic cystic lesions with fluid content such as arachnoid cysts. DWI can help obtain a correct diagnosis. We describe a case of iatrogenic lumbar epidermoid cyst with DWI findings in a young woman who had undergone epidural anesthesia for Cesarean section three years before the onset of symptoms.

Abstract
BACKGROUND Rotator cuff repairs in patients aged older than 65 years are reported to have a high failure rate. Furthermore, asymptomatic cuff tearing is frequent in this age group, so the value of tendon repair has been questioned. Our aim was to review the results of cuff repair in these patients and to identify factors predicting outcome. METHODS In this study, 58 patients aged older than 65 years with reparable supraspinatus tears underwent primary open (22 patients) or arthroscopic (36 patients) repair. The leading symptom was pain despite nonoperative treatment for at least 6 months. Tendon healing was assessed on ultrasonography. RESULTS Forty-four shoulders could be reviewed at a mean follow-up of 57 months (range, 24-112 months). Tendon healing was complete in 31 shoulders (70%). The mean Constant score (CS) improved from 49 points (range, 5-74 points) preoperatively to 78 points (range, 23-100 points) at follow-up (P < .05). The respective values for the relative CS were 64% (range, 7%-97%) and 95% (range, 33%-100%) (P < .05). The mean CS was better for healed repairs (82 points [range, 57-100 points]) than for nonhealed repairs (61 points [range, 23-88 points]) (P < .05). In 41 of 44 cases (93%), patients were satisfied or very satisfied with the operation. Though not statistically significant, dominance, cortisone injection, smoking, and tendon retraction appeared to favor nonhealing. CONCLUSIONS Isolated supraspinatus tendon repairs in patients aged older than 65 years have a high healing potential and yield good clinical results with even better outcome if the repairs heal. Repair of symptomatic single-tendon rotator cuff tears in patients aged older than 65 years who do not respond to conservative treatment appears justified.

Abstract
GH and PRL, although not considered as 'classi cal' sexual hormones, could play a role in the endocrine control of sexual function both in men and women. Physiologically, PRL seems to be involved in the central control of sexual behavior and activity, by modulating mainly the effects of dopaminergic and serotoninergic systems on sexual function. Indeed, circulating PRL levels increase after orgasm and may potentially play a role in the acute regulation of further sexual arousal following orgasm both in men and women. On the other hand, either short-term or long-term PRL in crease can modulate central nervous system areas involved in the control of sexual function and, peripherally, can directly influence mechanisms of penile erection in men, and presently only as an hypothesis, mechanisms related to the sexual response of genitalia in women. Furthermore, chronic hyperprolactinemia is classically associated with hypogonadotropic hypogonadism and sexual dysfunction in both sexes. Successful treatment of chronic hyperprolactinemia generally restores normal sexual function both in men and women although this effect is not only related to relapse of gonadal function. Hypoprolactinemia is recently recognised as a possible risk factor of arteriogenic erectile dysfunction while a possible role on female sexual function is not known. The physiological role of GH on sexual function is not fully elucidated. GH is an important regulator of hypothalamus-pituitary-gonadal axis and seems to participate in the regulation of the sexual response of genitalia in men, and potentially also in women. Sexual function in men and women with GH deficiency (GHD) and GH excess, particularly in acromegaly, is scantily studied and GH- or IGF-I-dependent effects are difficult to quantify. Nevertheless, a decrease of desire and arousability both in men and women, together with an impairment of erectile function in men, have been described both in patients with GHD and acromegaly, although it is not clear whether they are dependent directly on the hormone defect or excess or they are consequence of the hypogonadism or the different clinical complications or the physical disfigurement and psychological imbalance, which are associated with the diseases, and are potentially affecting sexual function. Data on beneficial effects of GH replacement therapy and specific surgical or pharmacological approach for acromegaly are far to be fully elucidated although restoring normal GH/IGF-I levels have been associated to improvement of sexual function.

Abstract
Some studies have suggested an overlap of clinical and genetic findings between essential tremor (ET) and Parkinson's disease (PD). The first genome-wide association study in ET showed a significant association with the rs9652490 SNP of the leucine-rich repeat and Ig domain containing 1 (LINGO1) gene. Since patients with PD have higher LINGO1 expression levels compared to healthy controls, and animal models of PD show elevated LINGO1 protein levels after experimentally induced damage in the striatum, it can be inferred that LINGO1 is probably involved in PD pathophysiology. In this study, we performed a genetic association analysis of the rs9652490 and rs11856808 SNPs in Italian PD patients and controls to assess the role of these variants in our population. A total of 567 patients with PD and 468 control subjects were enrolled in five Movement Disorder centers located in Central-Southern Italy. Both variants were significantly associated with PD under a recessive model of inheritance before applying the Bonferroni correction. The GG genotype of rs9652490 and the TT genotype of rs11856808 were less frequent in patients than in controls, suggesting a protective effect against the disease. However, after stringent correction, only the P-values obtained from allele and genotype comparisons of the rs11856808 SNP remained significant. Our findings suggest that LINGO1 plays a certain role in the development of PD in the Italian population and represents an interesting candidate gene responsible for PD, due to its involvement in neurological processes.

Abstract
We describe the brain MR imaging findings of a woman who developed neurologic symptoms due to an acute hyperammonemic encephalopathy resulting from late onset ornithine transcarbamylase deficiency (OCTD). MR images revealed injury (hyperintense foci on long TR images) to the subcortical white matter of the left precentral and supramarginal gyrus and in the left frontal lobe. These findings presumably reflect the distribution of brain injury from hypoperfusion secondary to severe hyperammonemia. If MR findings suggesting hypoperfusion are detected in a patient with hyperammonemia, the diagnosis of OCTD should be considered. Knowledge of the physiopathological mechanisms of OTCD and of MR imaging of hyperammonemic injury may help expedite diagnosis and treatment and prevent the exitus of patients with this genetic disorder.

Abstract
The amount and quality of information and awareness in cancer patients' is a topic frequently debated, but few studies have focussed on terminal patients. This is the objective of the present study that involved two different palliative home-care units in Italy, which recruited 550 terminal cancer patients. Data from patients and their caregivers was prospectively collected with special attention to information patients were provided with when their cancer was diagnosed and patients' awareness of their current health condition. In the case of the information, 67.0% of patients reported they were previously informed about their diagnosis, but only 58.0% seemed to be aware of their terminal condition. The comparison between the caregivers opinions about the level of information provided to the patients and their present awareness and what the patients really know about their own disease shows a high degree of correspondence. Some variables such as age and education level of patients were associated with patient's awareness.

Abstract
We have studied 180 patients (128 men and 52 women) who had undergone lumbar discectomy at a mean of 25.4 years (20 to 32) after operation. Pre-operatively, most patients (70 patients; 38.9%) had abnormal reflexes and/or muscle weakness in the leg (96 patients; 53.3%). At follow-up 42 patients (60%) with abnormal reflexes pre-operatively had fully recovered and 72 (75%) with pre-operative muscle impairment had normal muscle strength. When we looked at patient-reported outcomes, we found that the Short form-36 summary scores were similar to the aged-matched normative values. No disability or minimum disability on the Oswestry disability index was reported by 136 patients (75.6%), and 162 (90%) were satisfied with their operation. The most important predictors of patients' self-reported positive outcome were male gender and higher educational level. No association was detected between muscle recovery and outcome. Most patients who had undergone lumbar discectomy had long-lasting neurological recovery. If the motor deficit persists after operation, patients can still expect a long-term satisfactory outcome, provided that they have relief from pain immediately after surgery.

Abstract
BACKGROUND Celiac disease (CD) is a chronic intolerance to gluten, which induces intestinal mucosal lesions in genetically predisposed individuals. Transabdominal bowel sonography (TABS) is a safe and noninvasive procedure that allows to detect intestinal abnormalities in many conditions, but actually is not routinely part of the diagnostic management of CD. AIM To evaluate the diagnostic accuracy of TABS in CD patients. PATIENTS AND METHODS Fifty CD patients and 50 dyspeptic subjects (control group) underwent TABS. The presence of fluid-distended small bowel loops with thickened valvulae conniventes and increased peristalsis was considered a TABS sign of CD. All clinical, biochemical, and TABS features were assessed at the diagnosis and revaluated after 1 year of gluten-free diet. RESULTS TABS signs were present in 66% of CD patients. Sensitivity, specificity, positive and negative predictive value were 66%, 96%, 94%, and 74%, respectively. TABS findings were recorded in 82% of patients with endoscopical markers of CD, in 87.5% of symptomatic patients, and in 61% of patients without symptoms. After 1 year of gluten-free diet TABS was still abnormal in 20% patients, with no correlation with laboratory tests e/o symptoms. CONCLUSIONS Patients with CD frequently present TABS signs of the disease and operators performing sonography every day have to consider the possibility to suggest CD diagnosis and aTTG determination in these subjects.

Abstract
The giant cell tumor of the jaws is a rare benign lesion, it has a slow and progressive evolution and it is locally aggressive. Its etiopathogenesis is unknown, it is most common in the mandible and it is often asymptomatic but pain arises from palpation of the area. Diagnosis is made by radiological and histological examination and surgical treatment is necessary. The clinical case of a 28-year-old man affected by a giant cell tumor of the mandible with an aggressive clinical and radiographical behaviour is reported. The patient showed a jaw swelling covered by hyperemic fibro-mucous tissue from tooth 4.6 to 3.4, absence of cortical bone and mobility of teeth. He also reported lip anesthesia. The giant cell tumor diagnosis was made with orthopantomography (OPT), computed tomography (CT) and needle biopsy. The lesion was surgically removed and histological examination confirmed the diagnosis. In spite of the wide loss of bony substance after surgery, the patient was provided with an implant supported fixed prosthesis without previous bone graft. In this case short implants allowed the prosthetic rehabilitation of a mandible with severe ''resorption'' due to surgical removal of a tumor. Implants were placed in the residual bone volume and successfully used to support a fixed prosthesis. The final result is optimal as is the quality of life of the young patient.

Abstract
BACKGROUND Crohn's disease (CD) is frequently associated with extra-intestinal manifestations (EIMs) and infliximab has been recently proposed for the treatment of CD with EIMs. Our aim was to evaluate the short-term efficacy of infliximab in this treatment. PATIENTS AND METHODS Thirty CD patients were treated with infliximab. Fifteen patients (50%) showed EIMs before starting therapy. Ten patients presented an arthritis (five sacroiliitis, five spondylitis), with six also reporting peripheral arthralgias. Four patients presented cutaneous EIMs while three patients had an ocular EIM. RESULTS At week 10, all patients reported an improvement in EIMs. Regarding arthritis, ASAS20 and ASAS40 improvement was observed in 80% and 60% of patients, respectively. In the four patients with cutaneous EIMs and in the three with ocular EIMs, complete healing was observed. Recurrence was observed in 10 out of 15 patients (66%) and a second course of treatment with infliximab was required. This proved to be effective in all cases except for one patient who stopped treatment because of a severe adverse reaction. CONCLUSIONS Infliximab is an effective drug in the short-term treatment of EIMs complicating CD. Although relapse of EIMs occurs frequently, retreatment ensures effective control of the symptoms.

Abstract
BACKGROUND Oral squamous cell carcinoma is one of the most common cancers in the world. Reactive oxygen species are postulated to be involved in neoplastic transformation. The antioxidant defence system limits cell injury induced by reactive oxygen species. Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species and a cell's oxidant capacity or when there is a decrease in this capacity. This stress may cause mutagenesis, cytotoxicity and changes in gene expression that initiate or promote carcinogenesis. OBJECTIVES The present study was conducted to investigate whether tumor tissue and blood of patients with oral squamous cell carcinoma have altered antioxidants levels. METHODS Levels of antioxidants such as reduced glutathione (GSH) and ascorbic acid (AA) and the activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), glutatione reductase (GR), were estimated in the tumor tissue and blood of 18 oral squamous cell carcinoma patients and in 20 healthy subjects as control. RESULTS Significantly increased levels of GSH, GPx, GR and AA and significantly decreased activity of SOD were observed in tumor tissue (p < 0.001) and in tumor-free tissue of oral cancer patients as compared with healthy subjects. In contrast, decrease in antioxidants (GSH, GPx, GR and AA p < 0.001, SOD p < 0.05 respectively) was observed in the blood of oral cancer patients, as compared with healthy subjects. CONCLUSION The low levels of antioxidants in the blood of oral cancer patients may be due to their increased utilization to scavenge lipid peroxides as well as their sequestration by tumor cells. The enhanced antioxidant capacities in tumor tissues can make them less susceptible to oxidative stress, conferring a selective growth advantage on tumor cells. These finding suggest that normalization of the levels of these antioxidants might be used to reduce oral tumor malignancy.

Abstract
BACKGROUND Crohn's disease (CD) frequently involves the small bowel. Actually, the diagnosis of CD is made by ileocolonoscopy (IC) and small bowel enteroclysis (SBE), while trans-abdominal bowel sonography (BS) and Tc-99m-HMPAO leukocyte scintigraphy (LS) are only partially used in spite of their minimal invasiveness. AIM to compare the diagnostic accuracy of these procedures for the diagnosis of small bowel CD. PATIENTS AND METHODS in about two years a series of consecutive subjects underwent IC, SBE, BS and LS for either suspected or known small bowel CD. RESULTS Sensitivity, specificity, positive and negative predictive value for CD diagnosis of the studied procedures were respectively: 98%, 97%, 98% and 97% for SBE; 92%, 97%, 98%, and 88% for BS; 90%, 93%, 96% and 85% for LS. In addition, the parallel combined use of BS and LS led to overall sensitivity, specificity, positive and negative predictive value of 100%, 93%, 96%, 100%, respectively. CONCLUSION SBE, BS and LS are accurate procedures for the diagnosis of small bowel Crohn's disease. The use of BS and LS, particularly in combination, can be proposed as early diagnostic approach to subjects with a suspicion of disease.

Abstract
BACKGROUND Small bowel bacterial overgrowth is common in Crohn's disease but its treatment is not clearly defined. Metronidazole and ciprofloxacin are effective antibiotics in active Crohn's disease. AIM To investigate the efficacy of metronidazole and ciprofloxacin in the treatment of bacterial overgrowth in patients with Crohn's disease. PATIENTS AND METHODS We performed the lactulose breath test in 145 consecutive patients affected by Crohn's disease. Patients positive to the lactulose breath test underwent a glucose breath test to confirm the overgrowth. These patients were randomized in two treatment groups: metronidazole 250 mg t.d.s. (Group A) and ciprofloxacin 500 mg b.d. (Group B), both orally for 10 days. The glucose breath test was repeated at the end of treatment. The clinical outcome after therapy was also recorded. RESULTS Bacterial overgrowth was present in 29 patients (20%). Breath test normalization occurred in 13 out of 15 patients treated by metronidazole and in all 14 patients treated by ciprofloxacin (P = ns). In both groups antibiotic treatment induced an improvement of intestinal symptoms: bloating (Group A 85% and Group B 83%), stool softness (44% and 50%), and abdominal pain (50% and 43%). CONCLUSIONS Small bowel bacterial overgrowth is a frequent condition in Crohn's disease which can be effectively treated by metronidazole or ciprofloxacin.

Abstract
A novel system of body water elimination to be used for the treatment of edemas, based on superabsorbent cellulose derivatives able to absorb large amounts of water and water solutions, has been investigated. Hydrogels have been synthesized starting from water solutions of carboxymethylcellulose sodium salt and hydroxyethylcellulose, chemically crosslinked with divinylsulphone. Polyelectrolyte hydrogels displayed high sensitivity in sorption capacity to variations of the ionic strength and pH of the external solution, which is a key parameter for the application under investigation. Further, swelling properties have been modulated acting on the degree of crosslinking of the macromolecular network, and a direct method for the measurement of this parameter based on NMR solid-state analysis has been provided. The hydrogel biocompatibility has been studied in terms of its capacity either to induce nitric oxide and lactate dehydrogenase release by macrophages or influence their viability. The eventual release of toxic substances from the hydrogel was also investigated using Swiss 3T3 fibroblasts. The results obtained from the biocompatibility studies carried out in this work are consistent with the hypothesis that this gel may represent an alternative to diuretic therapies in those pathologic conditions in which edemas occur.

Abstract
A panel of fourteen different monoclonal antibodies was used for detection and analysis of antigenic determinants located on the outer surface protein A (OspA) of the spirochete Borrelia burgdorferi, which is a causative agent of tick-borne borreliosis (Lyme disease). Two main and several minor partially overlapping antigenic determinants have been found on the surface of the OspA protein of Borrelia burgdorferi sensu stricto (strain 297) by lanthanide competition fluoroimmunoassay. One of the main antigenic determinants is located in the N- and the other in the C-half of the OspA molecule. The involvement of the OspA protein in intact Borrelia burgdorferi sensu stricto (four bacterial strains have been analyzed: 297, B31, FR90-594, and CA90-742) is associated with retention of the above-mentioned two major antigenic determinants, but unlike the case of the isolated OspA they are partially overlapping with each other and with other antigenic determinants. The protein of the spirochete Borrelia afzelii (two bacterial strains have been analyzed: Ip-21 and Pko) contains only one antigenic determinant, which is the same as the main determinant of the OspA protein of Borrelia burgdorferi sensu stricto located in the N-half of the OspA molecule.

Abstract
BACKGROUND Because the orbital-malar complex has a peculiar anatomic constitution and position, it is at the third place for frequency of the fractures especially if we compare it with another skeleton's parts. Till now have been tested numerous materials with advantages but also some disadvantages used to rebuild the orbital floor. We thought it right to test a material with biocompatibility, easy handiness, chemical stability and elasticit, as PTFE membrane. METHODS We studied 40 cases of both sexes (age between 19 and 70 years) of orbital-malar complex fractures: 14 with isolated fractures, 20 with complexes fractures and 6 politraumatized. They show various degree prolapse of the orbital contents in the maxillary sinus. We make clinic examination and orthoptic analysis by Hess's screen, test of forced traction, axial and coronal TC. In all patients, surgery approach and methodology of plate application were the same. RESULTS All the floors had a optimal and immediate functional renewal; there wasn't any inflammatory reaction neither immediately nor after a two years follow-up. CONCLUSIONS In conclusion, the results show a lot of clinical and practical advantages of the PTFE membrane: the extreme biocompatibility and the easy handiness, the ductility and the low cost.

Abstract
Tissue transglutaminase (tTGase) is a GTP-binding Ca(2+)-dependent enzyme which catalyses the post-translational modification via epsilon(gamma-glutamyl)lysine bridges. The physiological role of tTGase is not fully understood. It has been shown that in cartilage the expression of tTGase correlates with terminal differentiation of chondrocytes. Recent evidence suggests that the GTP-binding activity of tTGase may play a role in the control of cell cycle progression thus explaining some of the suggested roles for the enzyme.tTGase activity is present in primary cultures of epiphyseal chondrocytes and increases transiently upon retinoic acid (RA) treatment. Increase in enzyme activity occurs upon RA addition and is accompanied by a parallel increase in protein and mRNA levels. Stimulation of tTGase expression by RA correlates with suppression of cell growth and occurs independently of cell adhesion and cell differentiation.tTGase expression is not observed in MC2, a permanent chondrocyte cell line derived from retrovirus infected chondrocytes. RA treatment fails to activate tTGase expression in MC2 cells and to completely suppress cell proliferation. Our findings lend support to the idea that tTGase might play a role in non-dividing cultured chondrocytes.

Abstract
Predisposition to Crohn disease (CD) seems to be genetically determined but, though several reports on the matter, the association between HLA antigens and the disease is still controversial. PCR-SSP high resolution typing in 107 CD patients, and in subgroups selected according to clinical features, showed a positive association with the rare haplotype DRB1*07, DQB1*0303 both in the overall patients (p = 0.002; pc = ns) and in the subgroup of nonfistulized patients (p = 0.0008; pc = 0.032). Moreover, the protective role of the haplotype DRB1*03, DQB1*0201 (p = 0.029) was confirmed also in Italian patients, whereas no strong association with HLA class I alleles has been found. In addition, variability of the HLA alleles frequency in CD subgroups was observed, supporting the hypothesis of a genetic heterogeneity of the disease and suggesting that HLA alleles distribution in selected groups may allow to identify patients with probably different prognosis or associated complications.

Abstract
The goal of this study is to analyze the importance of circulating biomarkers association in the management of patients affected by oral cancer. In this study a survey is made of the international experience from 1980 to 1990 based on the presence of CEA, LASA, SCC Ag, TPA, ferritina, CA-50 and others in patients affected by oral cancer and the sensitivity and specificity of these circulating biomarkers association are assessed. In patients with active disease, the results obtained at the time of diagnosis of oral cancer are not satisfactory due to poor specificity of these circulating biomarkers association. The conclusions is drawn that the circulating biomarkers association (especially CEA, SCC Ag, LASA, ferritin, TPA and CA-50) appears to be useful in the prognosis and staging of oral cancer, while their presence is not significative for the diagnosis.

Abstract
The authors carry out a review of the international literature on an alternative methodology to surgical therapy of lithiasis of the salivary glands, indicating information, limitations and possible complications. More than fifty papers by international authors were analysed regarding their experience on the use of electro-magnetic waves in the treatment of salivary gland lithiasis. It was observed that extracorporeal lithotripsy is an alternative and valid method to surgery, considering that the complications are negligible. Considering the expectations and the relationship between cost and advantage, extracorporeal lithotripsy can be considered as first treatment with surgery as second therapeutic choice.

Abstract
By a proteomic approach, we demonstrated in rat coagulating gland secretion the presence of a 120 kDa protein which shares at least 80% identity at the amino acid level with the most closely related kinesin heavy chain codified by the kinesin superfamily protein Kif5c gene. In addition, we identified 30 and 66 kDa proteolytic fragments of such a kinesin heavy chain-like protein, corresponding to the 73-299 N-terminal and 300-860 C-terminal regions, respectively. Finally, we demonstrated the occurrence in coagulating gland secretion of a 200 kDa protein probably derived by cross-linking reaction of the kinesin heavy chain-like protein with type IV transglutaminase. In fact, kinesin heavy chain-like protein and its 66 kDa proteolytic fragment were also found to act as effective acyl donor substrates for the enzyme in vitro.

Abstract
In adult rats bearing unilateral 6-hydroxydopamine (6-OHDA) lesions of the ascending dopaminergic neurons, a single administration of a dopamine (DA) receptor agonist results in strong sensitization ("priming") of contralateral turning in response to D2 and particularly D1 receptor agonists. In order to investigate the role of distinct environmental cues associated with the effect of the agonist during exposure to the primer, rats bearing 15-day-old unilateral 6-OHDA lesions were primed in their home cage with L-dopa or with saline. L-Dopa but not saline induced medium to low but steady contralateral turning. Three days later, challenge with the D1 agonist SKF 38393 in the home cage also resulted in contralateral turning in the rats previously primed with L-dopa, but not in those primed with saline. In a second experiment rats lesioned with 6-OHDA were primed in two different contexts (hemispheres versus cylinders) with a single administration of the D2/D3 agonist quinpirole (LY 171555: 0.2mg/kg s.c.) or saline. Three days later the rats were placed in hemispheres and tested for contraversive turning in response to saline or to SKF 38393. SKF 38393 elicited high rate contraversive turning independently of the environment where priming with quinpirole took place; on the other hand no conditioned contraversive turning was observed after saline. In a third experiment, the possibility of priming SKF 38393-induced turning by stimulation of nigral or striatal DA receptors was investigated. Rats lesioned unilaterally with 6-OHDA were locally infused on the lesioned side in the substantia nigra with SKF 38393 or in the striatum with quinpirole. Both these treatments elicited contralateral turning, the intranigral injection of SKF 38393 eliciting a stronger and longer lasting contraversive turning than intrastriatal quinpirole. Challenge with SKF 38393 (3mg/kg s.c.) 3 days later induced contralateral turning only in rats previously primed with intrastriatal quinpirole. The results of these studies are consistent with the idea that "priming" is an example of non-associative sensitization induced by stimulation of denervated striatal DA receptors and expressed as an increased efficiency of post-synaptic dopaminergic transduction in the striatum.

Abstract
Phenoxyalkanoic acids are a widely used class of herbicides. This work employed high-resolution 13C NMR to study the structural changes induced by humic substances and horseradish perodixase on 2,4-dichlorophenoxyacetic acid (2,4-D) 13C-labelled in the side chain. NMR spectra showed that humic substances chemically catalyze abiotic splitting of [13C]2,4-D into 2,4-dichlorophenol and [13C]acetic acid at pH 7 but not at pH 4.7. Peroxidase did not catalyze the oxidative degradation of [13C]2,4-D at any pH tested and inhibited the effect of humic substances. Catalytic degradation by humic substances was attributed to free-radical reactions enhanced by the stereochemical contribution of large conformational structures formed by heterogeneous humic molecules at neutral pH. Inhibition of 2,4-D degradation when humic substances were combined with peroxidase was explained by modification of both chemical and conformational humic structure due to peroxidase-promoted oxidative cross-coupling among humic molecules. Our findings show for the first time that the abiotic degradation of 2,4-D is catalyzed by dissolved humic substances at neutral pH.
