Abstract
To evaluate the expression, location and role of progesterone receptors (PRs) A and B in human chondrocytic cell lines, Western blotting, real time PCR analyses, transmission electron microscopy and immunogold assays were performed. By transfection and co-transfection assays, the influence of progesterone (OHPg) on estrogen receptor alpha (ERα) promoter activity was investigated. MTT and pAKT documented OHPg effects on chondrocytes survival. The PR-B and PR-A were both observed in human chondrocytes. The PR-B was evidenced both in the nucleus and in the cytosol of the cells. OHPg, through PR-B, induced ERα expression by acting at the ER promoter level affecting chondrocytes survival. We reported for the first time the expression of PRs in human chondrocytes. Interestingly, we described a novel mechanism via progesterone induction of ERα, which may explain, at least in part, the dramatic rise in OA prevalence among postmenopausal women.

Abstract
OBJECTIVE Postoperative urine retention (POUR) is a well-known complication after total joint arthroplasty (TJA). POUR is most commonly managed with an indwelling catheter. However, indwelling catheters have been associated with a substantial risk of urinary tract infection (UTI). The purpose of this study was to (1) evaluate the incidence of UTI and POUR in patient with indwelling urinary catheter after TJA, (2) identify the microorganisms responsible for catheter colonization, and (3) assess preoperative risk factors (gender, body mass index, hypertension, diabetes mellitus, smoking) associated with catheter colonization. PATIENTS AND METHODS Patients undergoing primary TJA with no preoperative bacteriuria were enrolled. Prior to the draping of the surgical site, each patient received an indwelling catheter that was inserted under sterile conditions and remained in place for 24 hours. Urine and tip catheter cultures were performed after catheter removal. RESULTS 55 patients (38 females and 17 males) were recruited (26 total knee and 29 total hip arthroplasties). POUR was not reported in any patient, and only 1 patient (1.8%) had UTI. Cultures of catheter tips were positive in 16 patients (29.1%). Only 1 of these patients had a positive urine culture. Enterococcus faecalis was the most common pathogen isolated. None of the preoperative variables was associated with the risk of catheter colonization. CONCLUSIONS Data from this study support early catheter removal after TJA. Predominant catheter-isolated bacteria are enteric species. The culture of a catheter tip specimen should be discouraged for the diagnosis of UTI within the firsts 24 hours after surgery.

Abstract
BACKGROUND Scientific information about the effects of implant therapy following a precise workflow and patient and operators' preferences should be considered to choose which implant treatment protocol to use, and to achieve patient's satisfaction and functional results. The aim of this study was to analyze implant rehabilitations with a fully digital workflow and compare this approach with a conventional one. METHODS This study comprises 64 patients treated with a fully digital approach and 58 patients treated using a conventional protocol. Patient and operator centered outcomes were assessed through two visual analogue scale (VAS) questionnaires. RESULTS The VAS questionnaire demonstrated better results for the digital workflow concerning anxiety, convenience, taste, nausea sensation, pain and breathing difficulties (p < 0.0001). The VAS questionnaire administered to the operators showed better scores for the digital approach in relation to anxiety, convenience, difficulties of the impression procedure and the workflow (p < 0.0001). A significant reduced mean time for the digital workflow as well as a reduced number of required visits were recorded. CONCLUSION The analysis of a fully digital and a conventional protocol showed better results according to patient and operators' preferences when a fully digital approach was used.

Abstract
Perfume encapsulates are widely used in commercial products to control the kinetic release of odorant molecules, increase storage stability and/or improve deposition on different substrates. In most of the cases, they consist of core-shell polymeric microcapsules that contain fragrance molecules. A current challenge is to design and produce polymeric materials for encapsulation that are both resistant and non-persistent. The selection of such eco-friendly formulations is linked to a deep understanding of the polymeric material used for encapsulation and its biodegradation profile. To collect this information, pure samples of capsule shells are needed. In this article we present an innovative quantification method for residual volatiles based on pyrolysis-GC-MS to enable validation of sample quality prior to further testing. The presented analytical method also led to the development of a robust and comprehensive purification protocol for polymers from commercial samples. Standard techniques are not suited for this kind of measurement due to the non-covalent embedding of volatiles in the 3D structure of the polymers. We demonstrated the confounding impact of residual volatiles on the estimated biodegradability of fragrance encapsulates.

Abstract
PURPOSE Facially malformed patients often present a variable degree of facial imbalance even after basal bone correction, and resolution of the residual hard- and soft-tissue deficiencies and asymmetries of the face are of great importance for achieving a satisfactory post-implant procedure result. The use of polyether ether ketone (PEEK) implants for maxillofacial reconstruction has been documented in the literature, but the number of patients who have received them is limited. The aim of this study was to evaluate the overall volumetric results in patients with facial imbalance after onlay custom implant positioning for mandible and fronto-orbital reconstructions. Analysis was performed by confronting volumes with the use of three-dimensional (3D) photogrammetry. METHODS Fifteen patients were eligible for PEEK implant placements, eight for mandibular angle reconstruction, and seven for fronto-orbital reconstruction. Pre- and post-surgical 3D images of each patient's face were acquired. Facial asymmetry was analyzed by comparing each face with its mirrored copy. RESULTS Three-dimensional analyses have shown that some degree of volume imbalance was still present in the patients with only 1.32 ± 1.02 mm residual discrepancy after treatment. CONCLUSION Results of the study were found to fall within clinically acceptable limits since an asymmetry rate of < 3 mm is considered to fall into the norm.

Abstract
STATEMENT OF PROBLEM Dentistry has evolved significantly with the introduction of digital technologies and materials; however, clinical evidence for the performance of the complete digital workflow for single implant-supported posterior crowns is lacking. PURPOSE The purpose of this cross-sectional retrospective clinical study was to compare the clinical outcomes of 2 types of implant-supported crown used to replace a single missing posterior tooth in a completely digital workflow: transocclusal screw-retained monolithic lithium disilicate crowns versus transocclusal screw-retained monolithic zirconia crowns. MATERIAL AND METHODS A total of 38 participants who had been provided with dental implants and transocclusal screw-retained monolithic lithium disilicate or zirconia single crowns were evaluated in the study. Clinical and esthetic outcomes were recorded after a 3-year follow-up. RESULTS Both groups had comparable clinical outcomes with a survival rate of 100%. In the lithium disilicate group, 89% of the participants were free of technical complications, and 95%, in the zirconia group. Only 1 patient experienced minor chipping affecting a lithium disilicate crown. All complications were considered minor and were easily resolved, and none of the participants required replacement of a crown. No biological complications were recorded in either group. CONCLUSIONS Within the limitations of this cross-sectional retrospective clinical study, monolithic lithium disilicate and zirconia screw-retained single crowns fabricated using computer-aided design and computer-aided manufacturing (CAD-CAM) and a fully digital workflow were found to be reliable and suitable clinical options for restoring a posterior missing tooth on a dental implant.

Abstract
INTRODUCTION The leading cause of pyogenic vertebral osteomyelitis is Staphylococcus aureus, and its incidence is rising, particularly in the elderly. We report an unusual case of cervical spondylodiscitis and epidural abscess mimicking Pott's disease. CASE REPORT A 67-year-old man was admitted to our institution with a 15-day history of neck pain radiating to the head, shoulders and left arm that was associated with weakness and paresthesia. Laboratory tests showed a mild leucocytosis and high levels of inflammatory markers. The MRI showed contrast enhancement of C6-C7 with an abscess infiltration extending to the intervertebral disc, the anterior epidural space, and the medullary cord. The patient had a medical history of a positive Mantoux tuberculin skin test 25 years prior, and the interferon-gamma release assay (IGRA) was positive for the identification of latent tuberculosis infection. All other examinations for diagnosis of spinal tuberculosis were inconclusive. Intravenous antibiotic therapy was initiated with teicoplanin 800 mg and levofloxacin 750 mg daily with a fast recovery of symptoms. CONCLUSIONS Cervical spondylodiscitis can be an unusual cause of severe neck pain with a challenging differential diagnosis. Conservative treatment should always be considered for patients without neurological symptoms as long as close follow-up evaluations are performed.

Abstract
This study aims to evaluate the effect of postoperative blood recovery with reinfusion drains on hematologic parameters and blood transfusion rate in patients undergoing total joint arthroplasty. Three-hundred-and-forty-four patient records were reviewed and 271 patients were included in the study; 56.8% of patients were treated with postoperative cell salvage procedure using reinfusion drains (PCS) and 43.2% had closed-suction drain (CSD) postoperatively. In comparison to the CSD group, the PCS group showed higher hemoglobin (Hb) levels on the first and second days postoperatively but no statistical differences were noted at the day of discharge. 75.2% and 37.7% of patients required blood transfusions in the CSD and PCS groups, respectively. The PCS group had a lower number of blood transfusions than the CSD group. At multivariate analysis, Hb loss rate was related to preoperative Hb values, total amount of drained blood and chronic antiplatelet therapy. The number of blood transfusions was related to preoperative Hb values, closed-suction drains, preoperative platelet count, TKA surgery and BMI. This study supports the use of PCS with reinfusion drains after THA and TKA at least for the short-term.

Abstract
This study aims to report the minimum 2-year follow-up results of the tantalum monoblock cup in primary THA and to identify possible outcome predictors. Eighty-eight porous tantalum monoblock acetabular cup in primary THA were reviewed. The Harris Hip Score (HHS) and the Short Form-36 Health Survey (SF-36) were used for the evaluation of outcomes. Radiographic evaluation included acetabular component orientation, presence of bone gaps, radiolucent lines, new bone formation and heterotopic ossifications. After a mean follow-up of 55.4±19.5 months, no component revision was noted. The HHS improved from 43.6±14.6 to 88.3±8.4 (P less than 0.001). The mean physical domain of the SF-36 did not significantly differ from that of age-matched, healthy subjects (P=0.072); the mean mental component of the SF-36 was significantly higher than that of age-matched, healthy subjects (P less than 0.001). Negative determinants of postoperative HHS (total adjusted R2=0.328) using tantalum monoblock cups were age at surgery (R2=0.164, P less than 0.001), female sex (R2=0.103, P less than 0.001), and acetabular inclination (R2=0.084, P equals 0.003).

Abstract
BACKGROUND It is debated whether percutaneous revascularization (PCI) of total coronary chronic occlusion (CTO) is superior to optimal medical therapy (OMT) in improving symptoms, left ventricular (LV) function and major adverse cardiac/cerebrovascular events (MACCE). Furthermore, CTO-PCI is a challenging technique, with lower success rate than in other settings. A systematic analysis of baseline LV function, infarction extent and ischaemic burden to predict response to revascularization has never been performed. PURPOSES To establish a CMR protocol to identify patients (pts) who can benefit most from CTO-PCI. Myocardial viability/ischaemia retains high biological plausibility as predictors of response to revascularization. Therefore, baseline viability (necrotic tissue extent, response to inotropic stimulation) and ischaemia (perfusion defect, wall motion abnormality during stress) will be studied as potential predictors of mechanical LV segmental improvement and ischaemic burden reduction in CTO territory (primary endpoint), LV remodelling and global function, Seattle Angina Questionnaire, and MACCE improvement (secondary endpoints) in the follow-up. METHODS Pts with CTO suitable for PCI undergo stress-CMR for viability/ischaemia assessment. Pts with normal LV function undergo adenosine, those with moderately-reduced ejection fraction (EF) and wall motion abnormalities high-dose dobutamine, pts with EF <35% low-dose dobutamine. All pts undergo late gadolinium enhancement and repeat the same scan at 12 ± 3 months, regardless of PCI success or decision for OMT. CONCLUSIONS A multi-parameter CMR protocol tailored on pts characteristics to study viability/ischaemia could help in identifying responders in terms of LV function, ischaemic burden and clinical outcome among pts suitable for CTO-PCI, improving selection of best candidates to percutaneous revascularization.

Abstract
The purpose of this study was to evaluate the clinical and radiological outcomes of 2 piezosurgical split techniques performed in conjunction with the sinus lift.The present retrospective study included 20 patients with edentulism of the posterior maxilla who had undergone the sinus lift and alveolar ridge split treatment separately or the sinus lift combined with the monoblock alveolar ridge split. Differences between these 2 techniques were analyzed.All the surrounding areas successfully produced an adequate bone volume for the insertion of implants. A clinical evaluation showed a mean vertical augmentation of 3.6 ± 0.4 mm in Group A and 3.2 ± 0.7 mm in Group B. With regards to the lateral augmentation, the clinical evaluation gives a mean gain of 5.2 ± 0.3 mm in Group A and 4.9 ± 0.5 mm in Group B. The mean vertical and horizontal bone augmentation recorded for both types of surgical procedures were comparable.The proposed surgical procedures enabled the tridimensional volume of the alveolar ridge to be recreated. This resulted in the creation of a natural contour of hard and soft tissues which enabled a functional and aesthetic rehabilitation of the edentulous posterior maxilla to be obtained.

Abstract
Phosphaturic mesenchymal tumor (PMT) is a rare mesenchymal neoplasm associated with tumor-induced osteomalacia involving bone and soft tissue that produces paraneoplastic hypophosphatemic osteomalacia. The common physiologic defect in this conditions involves an impairment in renal tubular phosphate reabsorption with a downregulation of renal 1α-hydroxylase activity, while calcium metabolism remains essentially unaffected. Microscopic features consist of spindle cells, multinucleated giant cells and calcifications embedded in a chondromyxoid matrix with variable cellularity and prominent vascularity. Approximately 95% of PMTs involve the extremities and appendicular skeleton, with only 5% occurring in the head and neck region. Localization in the head and neck is pretty uncommon, nose and paranasal sinuses are preferentially affected. Due to its rarity, the purpose of the study was to report a new case of PMT whose locations in temporomandibular joint was never reported in literature.

Abstract
Primary soft tissue sarcoma of the retroperitoneum is a rare disease. A series of 11 evaluable adult patients with retroperitoneal soft tissue sarcomas is reported. These patients were treated with complete surgery and adjuvant radiation therapy (total dose from 50 to 64 Gy) using an 18 MeV linear accelerator. After a median follow-up of 48 months (range, 6-84), 4 patients had a local-regional recurrence, 3 had distant metastases, and 4 died of progressive disease. Four-year estimated disease-free survival was 54.5% and overall survival was 70%. Treatment was well tolerated by most patients: 7 patients experienced moderate gastrointestinal toxicity, mainly nausea and diarrhea, during radiotherapy; 2 cases had weight loss > 15% at the end of the therapy; and chronic ileitis was observed in 2 cases. We conclude that adjuvant radiotherapy seems to reduce the incidence of local-regional recurrences in these patients. No radiation-induced irreversible injury was observed, but one young woman had amenorrhea after radiotherapy. Controlled clinical trials are warrented to define the role and effiectiveness of adjuvant radiotherapy and/or chemotherapy in retroperitoneal soft tissue sarcomas.

Abstract
Cardiotoxicity is rarely observed during cisplatin chemotherapy. A possible synergistic toxic effect of cisplatin with etoposide on cardiac electrical activity is discussed. A case of a 60-year-old woman with squamous cell lung carcinoma who developed paroxysmal supraventricular tachycardia during cisplatin chemotherapy is reported. The potential cardiotoxicity should be considered when cisplatin is combined with other cardiotoxic agents or used in patients with cardiac disease.

Abstract
Apocrine carcinoma of the skin is a rare tumor. Wide surgical excision with complete removal of the neoplasm is the standard therapy and this appears to offer the best chance of cure. Radiotherapy may be used in case of local relapse or regional lymph node involvement. Systemic chemotherapy has not proved to be effective in the treatment of this tumor. We report on a 46-year-old woman with a recurrent apocrine carcinoma of the scalp that had previously been treated with surgery, radiotherapy and chemotherapy (Al-Saraff schedule). The patient was responsive to a second-line systemic chemotherapy regimen consisting of a weekly combination of methotrexate and bleomycin, and achieved long-term progression-free survival.

Abstract
A series of 14 eyes (11 patients) with choroidal metastases from breast cancer were reported. The lesions were classified into three grades according to the severity and extent of involvement. Eleven eyes (9 patients) were treated by radiotherapy with two opposed lateral fields using a 4 MeV linear accelerator. The contralateral eye received a prophylactic irradiation. An average dose of 42 Gy was delivered (range, 30-50). Results of radiotherapy were the following: 5 CR and 2 PR in grade II (9 eyes) and 2 PR in grade III (2 eyes). We conclude that radiotherapy is useful to control choroidal metastases of breast cancer. No contralateral metachronous involvement was found. Quality of life of responders showed a marked improvement. Radiation-induced injury was not seen.

Abstract
The activity of some alkylating agents widely used in clinical practice was studied by an in vitro antimetabolic assay, which evaluates the interference of drugs on the incorporation of 3H-thymidine and 3H-uridine in short-term cultures of human tumors. The effect of CCNU, chlorambucil, cisplatin, melphalan, prednimustine, procarbazine and the pro-active derivatives of cyclophosphamide and ifosfamide, 4-hydroperoxycyclophosphamide and 4-hydroperoxyifosfamide, was tested on non-Hodgkin lymphomas, germ cell testicular tumors, breast and ovarian cancers. Similar effects were generally produced by the drugs on both DNA and RNA precursor incorporation, and the in vitro response rates were similar to those clinically obtained for the same tumor types by using the same drugs in monochemotherapy. The effects of different alkylating agents on the individual tumors were not significantly associated, except for the analogues 4-hydroperoxycyclophosphamide and 4-hydroperoxyifosfamide, for which a significant agreement rate was observed. No evidence of acquired resistance to 4-hydroperoxycyclophosphamide and cisplatin after clinical treatment with the same drug was found in samples from ovarian cancer and non-Hodgkin lymphoma, but there was a definite trend in germ cell testicular tumors to lower sensitivity to cisplatin in previously treated patients.

Abstract
Pseudoaneurysms are an uncommon complication of mandibular condylar-subcondylar fractures; however, if present, their recognition and management is mandatory to avoid life-threatening situations. The authors report a case of internal maxillary artery pseudoaneurysm rupture that occurred after an open reduction and internal fixation of a mandibular subcondylar fracture, along with a review of the literature.

Abstract
A number of antiangiogenic agents have been developed as pharmaceuticals and are currently being tested in clinical studies. Potential strategies to enhance the activity of angiogenesis inhibitors could be to combine them, or better still, to administer them either sequentially or concurrently with cytotoxic drugs. Chemotherapy would be a more appropriate initial choice for patients with advanced disease since cytostatic agents can induce a fast regression of the tumor and cancer-related symptoms. Antiangiogenic treatment could be used after chemotherapy in patients who achieve disease remission to prolong the time to progression, the symptom-free interval and the overall survival. Antiangiogenic treatment is likely to attain an important role in the adjuvant setting. In fact, it could be used for prolonged periods after radical surgery to maintain dormancy of residual tumor cells. In spite of these promising preclinical data, several points need to be clarified before the initiation of clinical trials. In fact, certain misconceptions may interfere with their optimum design and result analysis.

Abstract
Aims of the study. Studies on circulating VEGF have reported mixed results, possibly due to a lack of standardization of the pre-analytical phase. The aim of our investigation was to standardize the sampling procedure for the determination of VEGF in different blood fractions. Basic procedures. We evaluated various clotting times for obtaining serum in 30 subjects, as well as different procedures for the preparation of plasma Edinburgh anticoagulant mixture (EDTA, PGE1, theophylline) and CTAD. VEGF was also assayed in lysed whole blood. In vitro platelet activation was monitored by measuring the levels of PF4. VEGF and PF4 were measured using commercially available enzyme-linked immunoassays. Main findings. Clotting time increased the release of VEGF, which reached a plateau between 2 and 4 hours. The percent increase of VEGF at 2 hours ranged from 118% to 4515% (median 327%) compared to samples centrifuged within 10 min from withdrawal. VEGF was not different and PF4 was very low or undetectable in Edinburgh plasma and CTAD plasma, while it was significantly higher in sodium citrate plasma. VEGF in CTAD plasma was not correlated with platelet count or leukocytes. Serum VEGF did not correlate with the leukocyte number, but it correlated significantly with the platelet count. Principal conclusions. The procedures for sample collection described above are highly standardized and easy to perform in a routine setting. We therefore suggest systematic evaluation of VEGF in CTAD plasma, in serum (clotting for 2 hours at room temperature) and in whole blood, until prospective controlled clinical studies will have clarified in which blood compartment(s) VEGF provides clinically relevant information.
