Abstract
PURPOSE To introduce a digitally assisted technique to achieve the ideal soft and bone tissue interface for anatomic-driven pink free implant supported fixed prosthesis, and prefabricate an interim prosthesis to be used the day of the surgery as a prosthetic scaffold to condition the healing. METHODS The digital assisted soft tissue sculpturing (DASS) technique allows the previsualization of the ideal soft and bone tissue interface and fabricate a computer aided design computer aided manufacturing (CAD-CAM) anatomic-driven pink free complete arch interim prosthesis for the immediate loading. Bone and soft tissue interface as well as the interim prosthesis design are performed in a segmented multiple standard tessellation language (STL) file embedding the bone anatomy, the intraoral surface anatomy (dental and soft tissue), the digital wax-up and the implant positioning. The interim prosthesis is used as a prosthetic scaffold to guide the soft and bone tissue surgical sculpturing and regeneration. CONCLUSIONS The DASS technique is a predictable integrated digital workflow that simplifies the achievement of a scalloped tissue interface for pink free fixed implant prosthesis, reestablishing the mucosal dimension required for the protection of underlying bone while maintaining tissue health. The surgical sculpturing and maturation of the soft and bone tissue is driven and enhanced by the xenogeneic collagen matrix grafting and prosthetic scaffold effect of the digitally prefabricated interim prosthesis delivered the day of the surgery.

Abstract
A hyperinflammatory syndrome (HIS) may cause a life-threatening acute respiratory distress syndrome (ARDS) in patients with COVID-19 pneumonia. A prospective series of 100 consecutive patients admitted to the Spedali Civili University Hospital in Brescia (Italy) between March 9th and March 20th with confirmed COVID-19 pneumonia and ARDS requiring ventilatory support was analyzed to determine whether intravenous administration of tocilizumab (TCZ), a monoclonal antibody that targets the interleukin 6 (IL-6) receptor, was associated with improved outcome. Tocilizumab was administered at a dosage of 8 mg/kg by two consecutive intravenous infusions 12 h apart. A third infusion was optional based on clinical response. The outcome measure was an improvement in acute respiratory failure assessed by means of the Brescia COVID Respiratory Severity Score (BCRSS 0 to 8, with higher scores indicating higher severity) at 24-72 h and 10 days after tocilizumab administration. Out of 100 treated patients (88 M, 12 F; median age: 62 years), 43 received TCZ in the intensive care unit (ICU), while 57 in the general ward as no ICU beds were available. Of these 57 patients, 37 (65%) improved and suspended noninvasive ventilation (NIV) (median BCRSS: 1 [IQR 0-2]), 7 (12%) patients remained stable in NIV, and 13 (23%) patients worsened (10 died, 3 were admitted to ICU). Of the 43 patients treated in the ICU, 32 (74%) improved (17 of them were taken off the ventilator and were discharged to the ward), 1 (2%) remained stable (BCRSS: 5) and 10 (24%) died (all of them had BCRSS≥7 before TCZ). Overall at 10 days, the respiratory condition was improved or stabilized in 77 (77%) patients, of whom 61 showed a significant clearing of diffuse bilateral opacities on chest x-ray and 15 were discharged from the hospital. Respiratory condition worsened in 23 (23%) patients, of whom 20 (20%) died. All the patients presented with lymphopenia and high levels of C-reactive protein (CRP), fibrinogen, ferritin and IL-6 indicating a HIS. During the 10-day follow-up, three cases of severe adverse events were recorded: two patients developed septic shock and died, one had gastrointestinal perforation requiring urgent surgery and was alive at day 10. In conclusion, our series showed that COVID-19 pneumonia with ARDS was characterized by HIS. The response to TCZ was rapid, sustained, and associated with significant clinical improvement.

Abstract
Degenerative lumbosacral stenosis in dogs frequently involves L7-S1 foraminal stenosis and L7 nerve root compression. Surgical techniques to decompress the L7 nerve root include foraminotomy and intervertebral distraction. The objective of this study was to compare the effect of foraminotomy and intervertebral distraction on the total, cranial, and caudal compartmental volumes of the L7-S1 intervertebral neurovascular foramen (NF). CT images were obtained from eight canine lumbosacral (L5-CD1) specimens in the following sequential conditions: native spine (1), after dorsal laminectomy and partial discectomy of L7-S1 (2), after L7-S1 foraminotomy (3), after distraction with an interbody cage between L7 and S1 (4), after cage distraction stabilized with pedicle screw-rod fixation in neutral (5) and flexed position (6). The volume of the complete NF and its cranial and caudal subcompartments were calculated using the CT images and statistically compared between conditions. P < 0.05 was considered statistically significant. The volume of the complete NF was significantly increased after foraminotomy (mean ± standard deviation (146.8 ± 26.5%, P < 0.01) and after distraction (Condition 4, 121.0 ± 19.1%; Condition 5, 116.6 ± 29.3 %; Condition 6, 119.0 ± 21.8 %; P = 0.01) with no difference between the distraction conditions. Foraminotomy induced a significantly larger increase in total NF volume compared to distraction. Foraminotomy, but not distraction, induced a significant increase in volume of the cranial subcompartment (158.2 ± 33.2 %; P < 0.01). Foraminotomy is more effective in increasing the foraminal volume and especially the cranial subcompartment, which is where the L7 nerve root traverses the NF. Hence, foraminotomy may be more effective in decompressing the L7 nerve root.

Abstract
Ischaemic colitis (IC) is the most frequent form of ischaemia of the digestive tract. Due to the worldwide increasing use of medications, there is a growing interest in drug-induced IC. This study reports a rare case of IC directly due to amoxicillin-clavulanate intake. The objective of the study was to describe the evolution of this novel manifestation. An 18-year-old man, non-smoker, with an insignificant medical history, presented with diarrhoea and cramping abdominal pain that started the day following the end of a 10-day amoxicillin-clavulanate course for recent upper respiratory tract infection. Stool cultures including Clostridium difficile toxin testing were negative. Colonoscopy documented an erosive-ulcerative colitis of the sigmoid and the descending colon. Histological examination of the colon biopsies revealed an IC with focal pseudomembranous areas in the descending-sigmoid colon. Thrombophilia screening tests were negative. The patient was discharged from the hospital without symptoms, and another colonoscopy was performed 3 weeks after the previous one, which documented normal endoscopic and histological findings. Amoxicillin-clavulanate IC is a very rare condition and should be suspected once infectious diseases, vascular/haemodynamic causes and a prothrombotic/hypercoagulable state have been excluded. Immediate discontinuation of the antibiotic leads to rapid disease remission.

Abstract
The dog has been used extensively as an experimental model to study meniscal treatments such as meniscectomy, meniscal repair and regeneration. Accurate quantification of meniscal size and morphology are a crucial step for developing models of the meniscus. 3.0T magnetic resonance imaging (MRI) has been found to be highly accurate in analyzing the meniscus in both clinical and research fields. However, 3.0T MRI systems are still uncommonly used in veterinary medicine. The goal of the study was to compare meniscal volume measurements from 1.5T MRI system with 3.0T MRI system using proton density sequence, a clinically relevant protocol. The MR images were segmented to reconstruct 3D surface representations of both medial and lateral menisci to compare the meniscal volumes measurements. Average volume differences were 8.8% (P=0.42) and 8.9% (P=0.535) for medial and lateral meniscus, respectively. No significant volume differences were found between 1.5T and 3.0T magnetic resonance (MR) measurements, with high Pearson's correlation coefficient of r > 0.8 and the intraclass correlation coefficient (ICC) of 0.899. For inter- and intra-observer reproducibility, high correlation (ICC = 0.942 and 0.814) was observed, but with high variability for intra-observer reproducibility (lower bound 0.478, upper bound 0.949). We have shown that common clinical MR scanners and pulse sequences can be used to quantify dogs' meniscal volumes with good reproducibility. We believe that repeatable measurements of meniscal volumes using MR may provide a useful capability for assessment of postoperative results following meniscal treatments such as meniscectomy and meniscal regeneration.

Abstract
INTRODUCTION The present case report describes the surgical treatment of a traumatic craniodorsal luxation of the hip and a concomitant medial congenital luxation of the patella (3rd grade) in an 11-year-old Yorkshire Terrier. First the hip luxation was corrected with a cemented hip prosthesis. The femoral stem was inserted in slight anteversion (15°) with respect to the preoperative condition (5°), this contributed contrasting the medial traction of the femoral quadriceps on the patella, improving patellar luxation from 3rd to 2nd grade. However, the persistent patellar luxation and intermittent lameness reduced limb function and made a second intervention necessary. Four weeks after prosthetic surgery, a femoral trocleoplasty and lateral transposition of the tibial crest were performed to definitively re-establish a correct replacement of the patella in the femoral trochlea. No perioperative complications were found. At the final examination the patient did not show any lameness or pain that could be evoked when manipulating the surgically corrected limb. The surgical treatment allowed a restoration of the hip function and the alignment of the extensor mechanism of the femoral quadriceps and ensured a complete return to normal motor activities.

Abstract
INTRODUCTION We describe patient-specific surgical guide prototyping and surgical treatment of a complex antebrachial deformity in two skeletally mature dogs presented with chronic lameness. Computer-assisted surgery was elected to increase accuracy in the correction of the complex deformity. Radiographs and computed tomography (CT) scans revealed a biplane deformity with valgus, procurvatum and external torsion of the right radius in both cases. The pre-surgical planning started from the quantification of the angular deformity, followed by computer simulated correction and to end up with a rehearsal surgery on 3D printed bone models. During the surgery, the custom-made osteotomy guides closely fitted the bone, allowing for a precise corrective osteotomy, that was stabilized with two locking plates. Postoperative radiographs showed the successful correction of the deformity. Eight and 12 weeks postoperative follow up examinations showed improved lameness, weight-bearing and progression of bone healing in both dogs. Patient-specific surgical guides allowed for a satisfactory correction of the antebrachial deformity. Additional benefits of using customized surgical devices include standardization and reduced surgical time.

Abstract
PURPOSE To evaluate the influence of implant scanbody (ISB) material, position and operator on the accuracy of a confocal microscopy intraoral scanning (IOS) for complete-arch implant impression. METHODS An edentulous maxillary model with 6 internal hexagonal connection analogues was scanned with an extraoral optical scanner to achieve a reference file. Three ISBs made of different materials (polyetheretherketone (Pk), titanium (T) and Pk with a titanium base (Pkt)) were scanned with IOS by 3 operators. The resulting 45 test files were aligned to the reference file with a best fit algorithm. Linear (ΔX, ΔY and ΔZ-axis) and angular deviations (ΔANGLE) were assessed. Absolute values of the linear discrepancies were summed up to obtain a global measure of linear absolute error (ΔASS). Influence of ISB material, position and operator was statistically assessed using the mixed general linear model. RESULTS At multivariate analysis, whenΔASS was considered as response variable, it was identified a significant influence of material (p<0.0001) and position (p=0.0009) while no significant operator effect was detected. When ΔANGLE was considered as response variable, material and position significantly influenced the expected ΔANGLE (p=0.0232 and p<0.0001) and no operator effect was identified. CONCLUSIONS The investigated IOS for complete-arch digital impression was influenced by the ISB material with peek reporting the best results on both linear and angular measurements followed by titanium, peek-titanium resulting as the less accurate. Implant angulation affected significantly the linear deviations while implant position the angular deviations. Operator did not show any significant effect on the IOS accuracy.

Abstract
BACKGROUND The rehabilitation after wrist surgery is extremely important. An instructed therapy in hospital is widely practiced. However, a dependent aging society and rush life style in younger generation have precluded patients to access to the frequent formal therapy. With the advancement in telecommunication technology, we have invented an application for smartphone for home-based wrist motion rehabilitation. METHODS Twenty participants were included in four-week wrist motion rehabilitation programme after wrist surgery. Participants were instructed to use the application by physical therapist and informed details of home-based wrist rehabilitation. The feasibility of application was evaluated by satisfaction level in various aspects and the adherence to the therapy was monitored by function provided in the application. The degrees of motion were compared at the end of prescribed programme. RESULTS Patient satisfaction was consistently high in every aspects. Also, the adherence to the therapy was high (90.42%). Ranges of motion significantly gained in every plane of wrist motion ([Formula: see text]). CONCLUSIONS This novel smartphone application seems to be a promising and convenient alternative for patients who need to gain wrist motion without formal rehabilitation in the hospital. Adherence to the therapy is also easily traced with this application.

Abstract
BACKGROUND Chronic exertional compartment syndrome of the forearm is an uncommon condition, occurring in some populations such as athletes. The standard surgical treatment for professional athletes who cannot avoid trigger activity is an open forearm fasciotomy, which may require a long recovery time. The aim of this study is to present a new endoscopic single approach forearm fasciotomy technique and outcomes of at least 3 years follow up. METHODS We performed the endoscopic single approach forearm fasciotomy in 4 forearms in 3 men with the mean age of 25 years. All of the patients were evaluated at a mean follow up of 46 months using the Visual Analog Scale (VAS) for pain and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS DASH improved from 21.71 to 5.39, VAS score improved too All the patients referred pain absence after the stress test performed at 20 kilos and 40 kilos. In our series no post-operative complications were observed. CONCLUSIONS The new mini-invasive technique has proved to be safe, reliable in a long-term follow-up. The main advantage is the shortening of the recovering time, that leads to a faster return to the professional activity.

Abstract
OBJECTIVES This multicenter prospective clinical trial investigated immediately provisionalized, anodized, conical connection, tapered implants with platform shifting in maxillary anterior and premolar sites. MATERIALS AND METHODS Patients requiring single-tooth implant-supported restorations in maxillary anterior and premolar sites were enrolled. Implants were immediately provisionalized and evaluated at insertion, 6 months, and annually thereafter. Outcome measures were marginal bone level change (ΔMBL), cumulative survival rate (CSR), and success rate, soft-tissue parameters, and oral health impact profile (OHIP). ΔMBL and Pink Esthetic Score were analyzed using Wilcoxon signed-rank tests. CSR was calculated using life table analysis. Other soft-tissue parameters were analyzed using sign tests. RESULTS Of 94 enrolled patients (99 implants), 84 (88 implants) attended the 3-year follow-up. After an initial bone loss between implant insertion and 6 months (- 0.92 ± 1.23 mm), bone levels stabilized from 6 months to 3 years (0.13 ± 0.94 mm) with no significant change. The 3-year CSR was 98.9%, and the cumulative success rate was 96.9%. Papilla index scores of 2 or 3 were observed at 88.6% of sites at the 3-year visit compared with 32.8% at implant insertion. Improvements were observed for all other outcomes, including bleeding on probing, esthetics, plaque, and OHIP. CONCLUSIONS This restorative protocol was associated with high primary stability, patient satisfaction, stable bone levels, and an overall improvement of the soft tissue outcomes over a 3-year period. CLINICAL RELEVANCE The presented treatment is a viable option for single-tooth restorations of maxillary anterior teeth and premolars with successful short- to mid-long-term clinical outcomes.

Abstract
INTRODUCTION A 12-year old female miniature Poodle was presented because of a 4/4 right fore-limb lameness. The orthopedic examination demonstrated pain at palpation of the right shoulder and an abduction angle of 55 °. MRI examination confirmed injuries consistent with a traumatic medial shoulder instability with no evidence of shoulder dysplasia. A partial rupture of the subscapularis tendon and complete detachment of the cranial gleno- humeral ligament were confirmed with arthroscopy. The joint was successfully stabilized using an arthroscopic assisted prosthetic suture.

Abstract
This report shows a multi-compartmental lipoma that occupied a vast area of the hand volar compartment, the distal aspect of the Parona's space and infiltrated the dorsal compartment between the IV and V metacarpal bones. The mass was entirely removed through a dorsal approach, minimizing risks of neurovascular and tendinous lesions.

Abstract
We evaluated the frequency of serum antineuronal antibodies in a cohort of 39 neuroblastoma patients and related their presence to clinical features. Twelve patients displayed antineuronal antibodies at immunocytochemistry. Only one of these 12 patients suffered from a clinically overt paraneoplastic syndrome. No significant differences emerged between autoantibody-positive and autoantibody-negative patients in terms of progression-free and overall survival, although when only patients evolving to disease progression were considered, the time interval between diagnosis and progression was slightly longer in autoantibody-positive patients.

Abstract
The growing interest in minimally invasive implant placement and delivery of a prefabricated provisional prosthesis immediately, thus minimizing "time to teeth," has led to the development of numerous 3-dimensional (3D) planning software programs. Given the enhancements associated with fully digital workflows, such as better 3D soft-tissue visualization and virtual tooth rendering, computer-guided implant surgery and immediate function has become an effective and reliable procedure. This article describes how modern implant planning software programs provide a comprehensive digital platform that enables efficient interplay between the surgical and restorative aspects of implant treatment. These new technologies that streamline the overall digital workflow allow transformation of the digital wax-up into a personalized, CAD/CAM-milled provisional restoration. Thus, collaborative digital workflows provide a novel approach for time-efficient delivery of a customized, screw-retained provisional restoration on the day of implant surgery, resulting in improved predictability for immediate function in the partially edentate patient.

Abstract
SummarySurgical procedures such as total hip arthroplasty (THA) or femoral head and neck excision may be indicated as a treatment for traumatic coxo-femoral luxation that is complicated by pre-existing joint disease, concurrent fractures or recurrent luxation. The purpose of our study was to evaluate outcome after treatment of traumatic coxo-femoral luxation by THA. Medical records of dogs undergoing cemented THA from 1996 to 2002 were reviewed. Inclusion criteria were coxofemoral luxation resulting from severe external trauma and radiographic follow-up of at least 3 months. Ten dogs (12 THA) met the criteria for inclusion. Complications included THA luxation (n = 1) and a non-displaced peri-prosthetic femoral fracture (n = 1) that healed without further surgery. Median cumulative function scores from client questionnaires after THA were not significantly different in dogs with previously normal (8, range: 7-10), (n = 5) and dysplastic (9, range: 7–16), (n = 5) hips (P = 0.410). Six dogs were available for re-examination and force plate analysis at greater than 6 months post-THA, and none of these dogs had any visible lameness. Peak vertical force (% BWt) showed a trend towards being less in THA (60.8±5.1) than non-operated (68.1±6.1) hindlimbs (P = 0.057), whereas vertical impulse (% BWt x sec) was similar in THA (9.1±1.6) and non-operated (9.8±1.2) hindlimbs (P = 0.286). Our findings indicate that THA can be a successful treatment for traumatic coxo-femoral luxation, irrespective of the dysplastic status of the joint prior to injury.
