Abstract
BACKGROUND Transcranial magnetic stimulation (TMS) combined with electromyography (EMG) has widely been used as a non-invasive brain stimulation tool to assess excitation/inhibition (E/I) balance. E/I imbalance is a putative mechanism underlying symptoms in patients with schizophrenia. Combined TMS-electroencephalography (TMS-EEG) provides a detailed examination of cortical excitability to assess the pathophysiology of schizophrenia. This study aimed to investigate differences in TMS-evoked potentials (TEPs), TMS-related spectral perturbations (TRSP) and intertrial coherence (ITC) between patients with schizophrenia and healthy controls. MATERIALS AND METHODS TMS was applied over the motor cortex during EEG recording. Differences in TEPs, TRSP and ITC between the patient and healthy subjects were analysed for all electrodes at each time point, by applying multiple independent sample t-tests with a cluster-based permutation analysis to correct for multiple comparisons. RESULTS Patients demonstrated significantly reduced amplitudes of early and late TEP components compared to healthy controls. Patients also showed a significant reduction of early delta (50-160 ms) and theta TRSP (30-250ms),followed by a reduction in alpha and beta suppression (220-560 ms; 190-420 ms). Patients showed a reduction of both early (50-110 ms) gamma increase and later (180-230 ms) gamma suppression. Finally, the ITC was significantly lower in patients in the alpha band, from 30 to 260 ms. CONCLUSION Our findings support the putative role of impaired GABA-receptor mediated inhibition in schizophrenia impacting excitatory neurotransmission. Further studies can usefully elucidate mechanisms underlying specific symptoms clusters using TMS-EEG biometrics.

Abstract
The transcranial evoked potential (TEP) is a powerful technique to investigate brain dynamics, but some methodological issues limit its interpretation. A possible contamination of the TEP by electroencephalographic (EEG) responses evoked by the somatosensory input generated by transcranial magnetic stimulation (TMS) has been postulated; nonetheless, a characterization of these responses is lacking. The aim of this work was to review current evidence about possible somatosensory evoked potentials (SEP) induced by sources of somatosensory input in the craniofacial region. Among these, only contraction of craniofacial muscle and stimulation of free cutaneous nerve endings may be able to induce EEG responses, but direct evidence is lacking due to experimental difficulties in isolating these inputs. Notably, EEG evoked activity in this context is represented by a N100/P200 complex, reflecting a saliency-related multimodal response, rather than specific activation of the primary somatosensory cortex. Strategies to minimize or remove these responses by EEG processing still yield uncertain results; therefore, data inspection is of paramount importance to judge a possible contamination of the TEP by multimodal potentials caused by somatosensory input.

Abstract
OBJECTIVE Advanced forms of wrist osteoarthritis in the elderly are quite common and often under-treated, preferring a conservative management of the condition due to the age of the patient. However, in elderly people who are still active, sporty and physically demanding, surgical management of wrist osteoarthritis should be considered. Proximal Row Carpectomy associated with a Resurfacing Capitate Pyrocarbon Implant (RCPI), allows the management of a wide range of wrist arthrosis, involving both the radio-carpal and the mid-carpal joints. This treatment has been already reported as a solution in younger people affected by degenerative pathologies of the wrist, giving overall good results. Authors aimed at verifying how this technique could be useful in elderly patients, resolving the severe pain often related to this pathology and letting them recover strength and motion. PATIENTS AND METHODS This is a retrospective analysis involving 7 cases of elderly men (mean age = 68 y.o.), suffering from severe wrist arthritis and treated with RCPI between 2016 and 2021. RESULTS All patients reported a return to manual activities between 6 and 12 months after surgery, significantly improving pain. Two patients complained moderate pain under strain at follow-up, with residual difficulty in performing manual tasks. In all cases, an increase of strength and improvement in terms of stiffness was registered. No cases of infections or implant mobilization were reported. CONCLUSIONS RCPI combined with proximal row carpectomy shows satisfying results in all published studies and it has been confirmed in our series as well. Indications for this procedure should be widened to elderly people, as useful alternatives to more aggressive salvage procedures, such as total prosthesis or arthrodesis.

Abstract
Background During the pandemic, restrictions set by the Italian Government were primarily based on the regional level of key parameters including hospitalization and incidence rates. We aimed to build a specific plot to monitor trends and trigger early alerts, with daily updates publicly available on a National Portal. Methods A multidisciplinary team conceived and implemented a new composite plot, developing ad hoc R scripts on top of a specialised database, built in collaboration with the Ministry of Health. We calculated the doubling time Td as log(2)/log(1+r/100), where r is the daily change of target parameters and Td ranges between (0,+-infinity), and not determined for constant or missing values. We calculated Td daily, as either doubling (growth) or halving (decrease) time. To visualize trends, we assembled two different types of graphs: a bivariate plot showing the path of each point (Td, target parameter) over time, and a line plot of Td over time. The Y axis was inverted for doubling times, as lower Td indicate higher alert in this case. The two graphs were arranged in lines, using cutoffs for excessive high values for doubling times and low values for halving times. A third line was included to display trends of the target parameter over time. Results The plot was successfully realized and published on the Portal for all regions in February 2021 (https://www.agenas.gov.it/covid19/web/index.php?r=english%2Fdoubling&q=ITA&t=0). Since July 2021, we used the doubling plot to monitor the three main parameters adopted to set restrictions for Covid-19: a) occupancy rates in intensive care; b) occupancy rates in medical wards; c) weekly incidence rates. The plot highlighted growth trends and early alerts, particularly in the initial phases of growth. Conclusions The doubling plot can provide useful information to trigger early responses for pandemic control in decentralised governance. R code is available open source from AGENAS for free use. Key messages • The doubling plot was conceived and implemented on a National Portal to trigger early alerts of Covid-19 progression in Italian Regions and Autonomous Provinces. • The plot could be rapidly adapted to legislative parameters and can be useful in different situations to monitor epidemic growth and support public health policies.

Abstract
Issue/problem AGENAS supports the implementation of health policies in direct collaboration with Italian Regions and Autonomous Provinces. To improve public reporting, we aimed to complement the production of technical reports with new forms of timely communication, using National Portals. Description of the problem Between October-December 2020, we designed and implemented the Covid-19 National Portal, including a suite of targeted indicators, fully automated via ad hoc scripts written in php and R on top of a relational database using internal and external data sources. Targeted information was widely communicated and continuously updated. Dedicated sections on forecasting and resilience were delivered in collaboration with specialised academic institutions. In 2021, we deployed the Portal for the Transparency of Health Services, broadly oriented towards health issues, the location of services and performance indicators. Results Pre-post comparisons of web analytics for Jan-Apr 2020-2022 showed clear advantages of Covid-19 Portal. By Apr 2020, Italy had introduced national lockdown, while AGENAS covered the topic traditionally, recording 48,122 users overall, with daily peaks below 5,000 sessions. In 2021-2022, the number of users skyrocketed at 436,280, with daily peaks of 100,000 sessions, and 421,123 respectively, with daily peaks of 150,000 sessions. Visits to the Transparency Portal were considerably more limited. Lessons To be widely used, public health information needs to be relevant (responding to personal need close to home), understandable, accurate and timely. National Portals can gain efficiency through the mediation of search engines, enhanced by: targeted naming (url), coherent semantic perimeter (third level domain in a highly referenced institutional website), continuous updating, and impact factor (linked by authoritative websites). The Transparency Portal will take stock of these lessons to succeed in a new funded program of NextGenerationEU. Key messages • Relevant, understandable, accurate and timely dissemination for different types of audience may be effectively organised through National Portals. • Productive collaboration between health specialists and communication experts can enhance usability and actionability of National Portals for public health.

Abstract
Short rotation woody crops (SRWCs) can be a sustainable solution for producing biomass for bioenergy and, at the same time, mitigating CO2 emissions. Although the contribution SRWCs can give to the transition to a low-carbon energy economy, farmers are hesitant to introduce them, as they have a low added value and there are uncertain economic prospects for cultivating SRWCs. Therefore, this study aims to analyze the economic sustainability of poplar woodchip production in Central Italy. Thus, the work compares three plantations, characterized by different durations (one year, two years, and five years) and harvesting systems, to identify the solution with the optimal duration. The results show that the quinquennial harvesting system is the most advantageous according to all the indicators, whereas the biennial performs the worst.

Abstract
Trapeziometacarpal joint osteoarthritis is a common degenerative disease. Arthrodesis is a widespread historical surgical technique to treat this pathology, providing pain relief and stability and strength of the thumb. Nevertheless, pantrapezial arthritis and non-union are not uncommon complications, leading in some cases to revision surgery. No gold-standard procedure has been described for revision of trapeziometacarpal arthrodesis failure. We describe two cases of failed arthrodesis treated with trapeziectomy and suspension ligamentoplasty, a well-known, biological, low-cost, successful, and easy-to-perform procedure.

Abstract
Robust biomarkers for anti-epileptic drugs (AEDs) activity in the human brain are essential to increase the probability of successful drug development. The frequency analysis of electroencephalographic (EEG) activity, either spontaneous or evoked by transcranial magnetic stimulation (TMS-EEG) can provide cortical readouts for AEDs. However, a systematic evaluation of the effect of AEDs on spontaneous oscillations and TMS-related spectral perturbation (TRSP) has not yet been provided. We studied the effects of Lamotrigine, Levetiracetam, and of a novel potassium channel opener (XEN1101) in two groups of healthy volunteers. Levetiracetam suppressed TRSP theta, alpha and beta power, whereas Lamotrigine decreased delta and theta but increased the alpha power. Finally, XEN1101 decreased TRSP delta, theta, alpha and beta power. Resting-state EEG showed a decrease of theta band power after Lamotrigine intake. Levetiracetam increased theta, beta and gamma power, while XEN1101 produced an increase of delta, theta, beta and gamma power. Spontaneous and TMS-related cortical oscillations represent a powerful tool to characterize the effect of AEDs on in vivo brain activity. Spectral fingerprints of specific AEDs should be further investigated to provide robust and objective biomarkers of biological effect in human clinical trials.

Abstract
To achieve the UN 2030 Agenda Goals, and considering their complexity and multidisciplinary, Multi-criteria analysis appears to be a suitable approach to give a true support to public decision makers in defining policy lines. This study focuses on the application of the Multiple Reference Point Weak-Strong Composite Indicators (MRP-WSCI) and its partially compensatory version (MRP-PCI), to assess, in the framework of the UN 2030 Agenda, the sustainability of the 28 members of the European Union (pre-Brexit). Countries were analyzed and compared according to their conditions and progress against the 17 Sustainable Development Goals, considering three reference years: 2007, 2012 and 2017. The analysis shows that Nordic countries reach a good level of global sustainability, with values of the indicators, W-W-W and S-W-W, between 2 and 3; while the States of east Europe, in particular Romania, Bulgaria and Greece, stay at the worst levels, having overall indicators values less than 1.5. Furthermore, the results highlight how countries in the lower group have difficulties especially in social and economic sustainability. On the other hand, states with a good overall condition record the worst results in the environmental dimension, such as the Netherlands, which shows, for the year 2017, a value for this sphere less than 2, while in the other two show a good value (over 2.5).

Abstract
INTRODUCTION In carpal scaphoid fractures, the surgical treatment with screw is considered the gold standard; shape memory staple however presents substantial advantages. The authors report a study on unstable fractures of the scaphoid waist (type B1, B2, B5, according to Herbert classification) treated with shape memory staple on a large sample of patients, with the aim to confirm the usefulness of this method, the quality of reduction and fixation, the functional results, the time of union and the possible complications. MATERIALS AND METHODS A retrospective analysis of 131 patients with scaphoid waist fractures with minimum follow-up 1 year was performed. Staples were used in all cases; technical details are discussed. Outcome measures were: postoperative pain, flexion-extension wrist range, hand grip strength, radiographic consolidation, work absence. Herbert and Fisher Grading System was used to assess subjective, objective and radiographic results. RESULTS Consolidation was achieved in all cases of primary fractures (0-30 days) within three months after surgery, and within eight months in all but two cases of delayed unions (operated within 6 months of the injury). Pain was absent at follow-up in 79% of cases, never severe or unbearable, the average flexion-extension range achieved was 112°. Handgrip strength values were comparable to those of contralateral wrist in 75% of cases. Mean time lost at work was 7.4 weeks. No algo-distrophy or malunion were observed. Discussion CONCLUSIONS: Scaphoid waist fractures' treatment with shape memory staple should be considered as an excellent alternative to screw fixation.

Abstract
Abstract
In reaction time (RT) tasks corticospinal excitability (CSE) rises just prior to movement. This is preceded by a paradoxical reduction in CSE, when the time of the imperative (“GO”) stimulus is relatively predictable. Because RT tasks emphasise speed of response, it is impossible to distinguish whether reduced CSE reflects a mechanism for withholding prepared actions, or whether it is an inherent part of movement preparation. To address this question, we used transcranial magnetic stimulation (TMS) to estimate CSE changes preceding 1) RT movements; 2) movements synchronized with a predictable signal (predictive timing or PT movements); and 3) self-paced movements. Results show that CSE decreases with a similar temporal profile in all three cases, suggesting that it reflects a previously unrecognised state in the transition between rest and movement. Although TMS revealed reduced CSE in all movements, the TMS pulse itself had different effects on movement times. TMS given ~200 ms before the times to move speeded the onset of RT and self-paced movements, suggesting that their initiation depends on a form of trigger that can be conditioned by external events. On the contrary, PT movements did not show this effect, suggesting the use of a different triggering strategy prioritizing internal events.

Abstract
Background: Chronic, post-traumatic, avulsion of the proximal interphalangeal (PIP) joint volar plate represents a disabling lesion. The purpose of this report is to describe a flexor digitorum superficialis (FDS) tenodesis using a mini-bone anchor inserted into the proximal phalanx, and its clinical outcome. Methods: 15 patients with chronic post-traumatic hyperextension instability of the PIP joint were treated surgically. From the first post-operative day patients were invited to start an early gradual joint active motion, wearing an extension block splint. Forty days after surgery, clinical evaluations were carried out, including: joint stability, pain and range of motion (ROM). The use of a circumferential splint was recommended for two further months, avoiding strenuous manual activities. The range of motion, time lost at work and the functional results were recorded six months after surgery. Results: At last follow up, 7 of the 13 reviewed patients presented an excellent functional recovery, with complete resolution of pain and stability with attainment of ROM comparable to the contralateral finger. The others 6 patients obtained good results, with remission of the functional impairment and pain, with either residual hyperextension or flexion contracture. There was one case of recurrence consecutively to a premature traumatic work-related activity. Conclusions: The FDS tenodesis via a bone anchor, combined with early active PIP joint protected motion, was shown in this study to be effective and reliable.

Abstract
BACKGROUND AND PURPOSE Motor neuron disease (MND) refers to a spectrum of degenerative diseases affecting motor neurons. Recent clinical and post-mortem observations have revealed considerable variability in the phenotype. Rhythmic involuntary oscillations of the hands during action, resembling tremor, can occur in MND, but their pathophysiology has not yet been investigated. METHODS A total of 120 consecutive patients with MND were screened for tremor. Twelve patients with action tremor and no other movement disorders were found. Ten took part in the study. Tremor was recorded bilaterally using surface electromyography (EMG) and triaxial accelerometer, with and without a variable weight load. Power spectra of rectified EMG and accelerometric signal were calculated. To investigate a possible cerebellar involvement, eyeblink classic conditioning was performed in five patients. RESULTS Action tremor was present in about 10% of our population. All patients showed distal postural tremor of low amplitude and constant frequency, bilateral with a small degree of asymmetry. Two also showed simple kinetic tremor. A peak at the EMG and accelerometric recordings ranging from 4 to 12 Hz was found in all patients. Loading did not change peak frequency in either the electromyographic or accelerometric power spectra. Compared with healthy volunteers, patients had a smaller number of conditioned responses during eyeblink classic conditioning. CONCLUSIONS Our data suggest that patients with MND can present with action tremor of a central origin, possibly due to a cerebellar dysfunction. This evidence supports the novel idea of MND as a multisystem neurodegenerative disease and that action tremor can be part of this condition.

Abstract
Over a period of 8 years, 48 fingers with mallet fractures of Wehbé and Schneider Types 1 and 2, subtypes B and C, were treated in 31 men and 17 women of mean age 42 (range 17–61) years. The fractures included 5 Type 1 subtype B, 2 Type 1 subtype C, 23 Type 2 subtype B and 18 Type 2 subtype C fractures. The technique used consisted in passing a K-wire percutaneously from dorsal to volar and pinning the fracture fragment while leaving the distal interphalangeal joint free to allow immediate postoperative mobilisation. Fracture splintage was removed at 6 weeks. The results at 8 weeks, which remained unchanged at 12 months in 46 fingers, were assessed as excellent in 11, good in 35 and fair in two cases by the Crawford rating system. One case of pin track infection required early removal of the pin.

Abstract
In healthy subjects (HS), transcranial magnetic stimulation (TMS) applied during 'linguistic' tasks discloses excitability changes in the dominant hemisphere primary motor cortex (M1). We investigated 'linguistic' task-related cortical excitability modulation in patients with adductor-type spasmodic dysphonia (ASD), a speech-related focal dystonia. We studied 10 ASD patients and 10 HS. Speech examination included voice cepstral analysis. We investigated the dominant/non-dominant M1 excitability at baseline, during 'linguistic' (reading aloud/silent reading/producing simple phonation) and 'non-linguistic' tasks (looking at non-letter strings/producing oral movements). Motor evoked potentials (MEPs) were recorded from the contralateral hand muscles. We measured the cortical silent period (CSP) length and tested MEPs in HS and patients performing the 'linguistic' tasks with different voice intensities. We also examined MEPs in HS and ASD during hand-related 'action-verb' observation. Patients were studied under and not-under botulinum neurotoxin-type A (BoNT-A). In HS, TMS over the dominant M1 elicited larger MEPs during 'reading aloud' than during the other 'linguistic'/'non-linguistic' tasks. Conversely, in ASD, TMS over the dominant M1 elicited increased-amplitude MEPs during 'reading aloud' and 'syllabic phonation' tasks. CSP length was shorter in ASD than in HS and remained unchanged in both groups performing 'linguistic'/'non-linguistic' tasks. In HS and ASD, 'linguistic' task-related excitability changes were present regardless of the different voice intensities. During hand-related 'action-verb' observation, MEPs decreased in HS, whereas in ASD they increased. In ASD, BoNT-A improved speech, as demonstrated by cepstral analysis and restored the TMS abnormalities. ASD reflects dominant hemisphere excitability changes related to 'linguistic' tasks; BoNT-A returns these excitability changes to normal.

Abstract
BACKGROUND Eczema is one of the most common chronic inflammatory skin diseases, affecting about 20% of children. The pathogenic mechanisms of eczema are still not fully understood, and current treatment of moderate-severe eczema is often difficult. Recently, it has been suggested that Vitamin D plays a key role in this disease, even if mechanisms are only partially known. OBJECTIVE The purpose of our study was to assess the 25-Hydroxyvitamin D serum levels in a pediatric population suffering from chronic eczema (IgE-mediated and non-IgE-mediated), and to correlate these phenotypes with the SCORAD severity and selected clinical and biological parameters. Moreover, we aimed to evaluate whether a supplementation of Vitamin D3 could affect the same clinical and laboratory parameters. METHODS 89 children with chronic eczema were enrolled in the study. Severity of eczema was assessed with the SCORAD index. Past and present history was taken, and patients were divided into two groups according to the state of sensitization. According to a randomization schedule, the enrolled children were assigned to the following groups: supplementation group, which received a daily oral Vitamin D3 supplementation (2000 IUs) for 3 months; control group which received no supplementation. RESULTS Vitamin D concentrations in patients with moderate and severe eczema were not statistically different from Vitamin D concentration detected in the serum of patients with mild eczema. Furthermore, we did not find any correlation between Vitamin D levels, total IgEs and SCORAD index, both in the Sensitized and in the Not-Sensitized group. The Vitamin D3 supplementation did not influence the SCORAD severity or the total IgEs concentration. CONCLUSION To our knowledge, our study is the first one that shows no correlation between serum levels of Vitamin D, eczema severity and IgE sensitization in a pediatric population suffering from chronic eczema.

Abstract
OBJECTIVE Paracetamol /codeine has shown a strong analgesic activity in several studies conducted among different kind of subjects, including those with trauma. Nevertheless, its efficacy in patients accessing the Emergency Department (ED) for different kind of pain has never been tested. PATIENTS AND METHODS This is a cross-sectional, observational, prospective, cohort study. Inclusion criteria were patients > 18 year old presenting to the ED for localized traumatic or inflammatory pain involving only extremities. Numeric scale (NRS) was recorded thirty minutes and two hours after the administration of the analgesic therapy, consisting of 15 mg of ketorolac or 1000 mg/60 mg of paracetamol/ codeine, both orally. RESULTS Two-hundred patients were consecutively enrolled; 87 were treated with paracetamol/codeine and 113 with ketorolac. The combination paracetamol/codeine resulted to be not inferior to ketorolac in non-traumatic pain group and trauma group (p = 0.635 and p = 0.482, respectively). Compared to ketorolac, the combination paracetamol/codeine exerted a significantly higher analgesic activity in patients with fractures and muscular pain (p = 0.044) and was more effective in acute pain (p = 0.002), with a significant effect two hours after the administration (p = 0.029). CONCLUSIONS Paracetamol/codeine is equivalent to ketorolac in non-traumatic pain and post-traumatic pain, but is superior in acute pain and in patients with fractures and muscular pain. Those results play in favor of the use of the combination paracetamol/codeine in patients accessing the ED for non-traumatic or traumatic pain of the extremities.

Abstract
BACKGROUND Rupture of ulnar collateral ligament of the thumb (UCL) represents a frequent injury of the hand. Surgical repair is considered the gold standard but postoperative immobilization causes partial stiffness in a percentage of cases. AIM The aim of this paper was to assess the effectiveness of a postoperative functional hand-based splint for the thumb which allows immediate postoperative motion. DESIGN Randomized prospective clinical trial. SETTING The study was carried out at the Orthopedics and Hand Surgery Unit of The Catholic University School of Medicine, Rome, Italy. POPULATION Thirty consecutive patients, with a diagnosis of acute complete tear of the UCL, were selected to be treated surgically (predominantly men, mean age 39). Cases presenting associated injuries were not included. METHODS Patients were randomized postoperatively into 2 groups of 15 (one using the new splint and the other using a standard spica splint). After four weeks of splinting, clinical outpatient evaluations were carried on (at one, two, six, twelve months) on both groups to evaluate: joint stability; pain; pinch strength; range of motion; time lost from work; sessions of physiotherapy. RESULTS Immediate postoperative motion of the operated joint produced faster and better functional results. No cases of recurrence were recorded. CONCLUSIONS Surgical repair, combined with active metacarpophalangeal motion allowed by the new functional splint, was effective, safe and well tolerated. CLINICAL REHABILITATION IMPACT Enhancing the patients' function and reducing the time of functional recovery, the reported treatment presents potential advantages in the management of this frequent acute hand injury.

Abstract
The authors present the procedure and results of five years of arthroscopic treatment of wrist radiocarpal and midcarpal ganglia. Thirty cases of dorsal ganglia and seventeen cases of volar ganglia were operated on arthroscopically. The technique was easy to perform in all the radiocarpal ganglia, not easy in midcarpal dorsal ganglia and very difficult in midcarpal volar ganglia. The results were recorded with a mean follow-up of 15 months. Twenty-seven cases of dorsal ganglia and twelve cases of volar ganglia had excellent results with active motion recovery, no complications, absence of scars and no recurrence. Two cases had a recurrence. There were four complications: a case of injury of a radial artery branch, a case of extensive haematoma, and two cases of neuropraxia. In three cases the procedure was converted into open surgery: they had a longer time of healing and a residual scar. The arthroscopic resection has been in our experience effective and safe for the treatment of all radiocarpal ganglia. Good results have been obtained also in the treatment of dorsal midcarpal ganglia. Concerning the uncommon cases of volar midcarpal (STT) ganglia, an open approach seems still indicated.

Abstract
BACKGROUND Trapeziectomy and ligament reconstructions are favoured by surgeons concerned that telescoping of the thumb may reduce its function. However, theoretically ligamentoplasties are at risk to develop tendinosis or tendon rupture or trigger a complex regional pain syndrome type 1. HYPOTHESIS Authors tested the looping of a slip from the abductor pollicis longus (APL) tendon around the first intermetacarpal ligament. They intended to use a surgical treatment which does not require bone tunnelling or looping around a tendon. Their results support the hypothesis that this new technique is a valid addition among treatments for carpometacarpal arthritis. PATIENTS AND METHODS Forty-two patients were followed up to one year. Each patient had subjective assessment for: pain; function (DASH score); overall satisfaction. An objective assessment was used for: first web span angle; abduction and opposition; key pinch; grip strength. Tests were performed prior to surgery, then at three, six and 12 months. X-ray films were taken to monitor thumb height. RESULTS A substantial improvement in all these parameters was measured in all patients. X-ray films showed the mantainance of a physiological heigth after one year. We recorded one complication of keloid and two of temporary dysesthesia but no case of tendinosis, delayed rupture, or CRPS 1. Mean operative time was 27 minutes. DISCUSSION Simplification and search for a technique which avoids the looping around a tendon is why the authors undertook this study. Advantages are the small number of required steps, short time of surgery and comfortable postoperative rehab regimen for the patient. The technique provides a distal anchoring point (without bone tunnelling). It is quite respectful of anatomy and physiology, in minimizing the re-routing of functioning tendons. We propose it as an effective procedure both to expand the armamentarium for treating the thumb carpometacarpal joint osteoarthritis and/or to simplify the ligamentoplasties already in use.

Abstract
Stitch suture is still the most recommended method to hold a nerve-guide in place but stitch suture is a well known cause of local inflammatory response. Glues of several kinds have been proposed as an alternative but they are not easy to apply in a real surgical setting. In 2006 authors developed a new concept of nerve-guide termed "NeuroBox" which is double-halved, not-degradable and rigid, and allows the use of cyanoacrylic glues. In this study, Authors analyzed histologically the nerve-glue interface. Wistar rats were used as animal model. In group 1, animals were implanted a NeuroBox to promote the regeneration of an experimentally produced 4 mm gap in the sciatic nerve. In group 2, the gap was left without repair ("sham-operated" group). Group 3 was assembled by harvesting 10 contralateral intact nerves to document the normal anatomy. Semi-thin sections for visible light microscopy and ultra-thin sections for Transmission Electron Microscopy were analyzed. Results showed that application of ethyl-2-cyanoacrylate directly to the epineurium produced no significative insult to the underlining nerve fibers nor impaired nerve regeneration. No regeneration occurred in the "sham-operated" group.

Abstract
The Epibloc system of percutaneous endomedullary internal fixation is best indicated for AO type A2-3 extra-articular fractures of the distal radius and AO type C1 slightly comminuted articular fractures. This system includes pins that can be inserted into the medullary canal and advanced without breaking through the second cortex. This fixation is stabilised by an external plate and rendered dynamic by the pins' elasticity which compresses the fractured surfaces. Moreover, this system results in transversal ligamentotaxis which helps prevent secondary reduction losses. The result of a preliminary series of 326 cases is evaluated.

Abstract
PURPOSE The study of the in-vivo regeneration of a nerve, made by purely histological methods, requires a high number of animals: this poses serious problems of technique, ethics and funding. A cheaper analysis, performed on the same animal along the duration of a study, is seeked with favour and Authors wanted to evaluate gait recovery after sciatic nerve transection as a non-invasive method to evaluate the performance of an artificial nerve-guide in rats. METHODS Male Wistar rats (n=16) were divided into three groups: in group A (n=5) the experimental gap produced was bridged by a custom-made guide; in group B (n=7) animals were "sham-operated"; in group C (n=4) a PMMA cap sealed the proximal nerve stump. RESULTS In group A a regenerated nerve was retrieved after 8 weeks, in all animals. In group B it was possible to retrieve mostly bulbous neuromatous stumps. In group C all the animals presented a voluminous neuroma. Signs of auto-mutilation had the following distribution: 1/5 in group A; 4/7 in group B; 3/4 in group C. A clear difference in gait recovery exists only between group C (no recovery) and the two other groups (early recovery in both). CONCLUSIONS The present study highlights that in the male Wistar rat sciatic model a spontaneous recovery in gait pattern occurs very early (within the first or second week); with this animal model, a recovery in gait is likely to ensue irrespective of the kind of device eventually tested since it may happen even without a device.

Abstract
This study reports the outcome of a series of ten microsurgical fingertip reconstructions with partial toe transfers in which the vascular pedicle was exteriorised and subsequently excised after the transfer had become established. The aim of this technique was to provide better aesthetic and functional outcomes. The technique was successful and without complication in nine of the ten patients who had excellent functional and aesthetic outcomes. Arterial thrombosis resulted in partial necrosis of the fingertip in the other case.

Abstract
Body lean response to bilateral vibrations of soleus muscles were investigated in order to understand the influence of proprioceptive input from lower leg in human stance control. Proprioceptive stimulation was applied to 17 healthy subjects by two vibrators placed on the soleus muscles. Frequency and amplitude of vibration were 60 Hz and 1 mm, respectively. Vibration was applied after a 30 s of baseline. The vibration duration of 10, 20, 30 s respectively was used with following 30 s rest. Subjects stood on the force platform with eyes closed. Postural responses were characterized by center of pressure (CoP) displacements in the anterior-posterior (AP) direction. The CoP-AP shifts as well as their amplitudes and velocities were analyzed before, during and after vibration. Vibration of soleus muscles gradually increased backward body tilts. There was a clear dependence of the magnitude of final CoP shift on the duration of vibration. The amplitude and velocity of body sway increased during vibration and amplitude was significantly modulated by duration of vibration as well. Comparison of amplitude and velocity of body sway before and after vibration showed significant post-effects. Presented findings showed that somatosensory stimulation has a long-term, direction-specific influence on the control of postural orientation during stance. Further, the proprioceptive input altered by soleus muscles vibration showed significant changes in postural equilibrium during period of vibration with interesting post-effects also.

Abstract
OBJECTIVES Arthroscopy represents a new and promising technique for the diagnosis and treatment of disorders of the wrist. Causes predis posing to clinical failure can arise during any phase of the approach to a patient who is a candidate for arthroscopic treatment. The author examine the causes of failure during pre-operative diagnostic workup, operative procedure and post-operative rehabilitation program and discus how to prevent them. MATERIALS AND METHODS Three hundred fifty outpatients who had wrist arthroscopy were reviewed to determine type of procedure, type of anaesthetic, portals used and incidence and nature of preoperative, operative, and postoperative complications. Complications were divided in two groups: major and minor. The first group consists of isolated or combined vascular, nerve and/or tendon injuries, compartment syndrome joint infection and RSD, wrist rigidity. The second group includes transient superficial dorsal ulnar sensory neurapraxia, superficial portal sit infection, skin burns, tendonitis, instrumentation breaking inside the wrist joint, ganglion formation, haematomas. In a separate group othe causes of failure, especially those due to surgical or rehabilitation failures, are considered. RESULTS Ten cases of surgical and post-surgical complications (2,9%) and 8 other cases of failure considered separately (2,3%) were identified, making a total of 18 cases of clinical failure (5,1%). Among these complications 4 cases were classified as "major" [sensory nerve branch lesions of ulnar nerve (3 cases) and of radial nerve (1 case)] and 6 cases were classified as "minor" [sensory neurapraxia (3 cases), instrumentation breakage (1 case), ganglion formation (1 case), a large subcutaneous haematoma (1 case)]. CONCLUSIONS Wrist arthroscopy is a sophisticated procedure, requiring dedicated surgical training and a thorough knowledge of joint disorders in order to lower the risks of complications and surgical failures.
