Abstract
We used high-resolution ultrasound to examine 35 median nerves (35 patients) with failed carpal tunnel decompression to identify the cause of failure. The carpal tunnel was examined before revision surgery, and the results were correlated with surgical findings. The cross-sectional area was measured, and nerve morphology was analysed at the sites of compression. We found persistent median nerve compression in 30 out of 35 patients. In 20 patients, the compression was caused by a residual transverse carpal ligament, in four by perineural fibrosis, in five by both of these causes and in one by tenosynovitis. In four patients, evidence of median nerve injury with an epineural/fascicular lesion was detected; and in one, no abnormalities were found. Surgical findings were consistent with the ultrasound findings except in one patient where tenosynovitis was associated with a giant cell tumour, which was missed by ultrasound. High-resolution ultrasound can provide helpful information in preoperative diagnosis of failed carpal tunnel decompression with good correlation between the ultrasound and surgical findings.Level of evidence: IV.

Abstract
The AAOMS in 2014 changed from BRONJ to the term Medication-Related Osteonecrosis of the Jaw (MRONJ), because of the growing number of osteonecrosis cases associated with other antiresorptive and antiangiogenic therapies. Even if the drugs involved are different, the histopathological findings are the same. Colonies of Actinomyces are encountered in most cases. The aim of the present study is to report on Actinomyces prevalence among the cases of MRONJ, taking into consideration also antiresorptive and antiangiogenic therapies in the literature and in our sample between 2005 and 2020. The review was performed using the database Medline the linkage between Actinomyces infection and MRONJ. The retrospective study was conducted on patients between with clinical and radiological manifestations of MRONJ May 2005 and February 2020. A total of 42 articles were found, 30 publications have been taken into consideration for the review. A total of 114 patients have been examined at the Padua Hospital. A total of 101 oncological patients presented the histological confirmation of MRONJ. 83 specimens revealed the presence of Actinomyces infection (82.18%). Actinomyces-associated lesions are frequent and present a wide spectrum of clinical manifestation.

Abstract
BACKGROUND AND AIM The objective of this cross-sectional study was to evaluate the degree of glycaemic control and the frequency of diabetic complications in Italian people with diabetes who were treated with continuous subcutaneous insulin infusion (CSII). METHODS AND RESULTS Questionnaires investigating the organisation of diabetes care centres, individuals' clinical and metabolic features and pump technology and its management were sent to adult and paediatric diabetes centres that use CSII for treatment in Italy. Information on standard clinical variables, demographic data and acute and chronic diabetic complications was derived from local clinical management systems. The sample consisted of 6623 people with diabetes, which was obtained from 93 centres. Of them, 98.8% had type 1 diabetes mellitus, 57.2% were female, 64% used a conventional insulin pump and 36% used a sensor-augmented insulin pump. The median glycated haemoglobin (HbA1c) level was 60 mmol/mol (7.6%). The HbA1c target (i.e. <58 mmol/mol for age <18 years and <53 mmol/mol for age >18 years) was achieved in 43.4% of paediatric and 23% of adult participants. Factors such as advanced pump functions, higher rate of sensor use, pregnancy in the year before the study and longer duration of diabetes were associated with lower HbA1c levels. The most common chronic complications occurring in diabetes were retinopathy, microalbuminuria and hypertension. In the year before the study, 5% of participants reported ≥1 episode of severe hypoglycaemic (SH) episodes (SH) and 2.6% reported ≥1 episode of ketoacidosis. CONCLUSIONS Advanced personal skills and use of sensor-based pump are associated with better metabolic control outcomes in Italian people with diabetes who were treated with CSII. The reduction in SH episodes confirms the positive effect of CSII on hypoglycaemia. CLINICAL TRIAL REGISTRATION NUMBER NCT 02620917 (ClinicalTrials.gov).

Abstract
AIM Anxiety is a relevant problem in dental practice. The Modified Dental Anxiety Scale (MDAS) is a brief, simple questionnaire consisting of five questions with a total score ranging from 5 to 25, the Italian version of which is not available yet. The aim of the study was to provide an Italian version of the MDAS and check its reliability in oral surgery, which is a major cause of dental anxiety due to the expected perception of pain and suffering. METHODS The Italian version of the test was administered to 230 patients (98 male and 132 female patients, ages 14-88 years) undergoing oral surgery. Further recorded data were: American Society of Anaesthesiologists physical status classification (ASA-PS), frequency of visiting the dentist and any previous distressing experiences in dental or medical setting. RESULTS The internal consistency of the test was high, with a Cronbach's alpha=0.92. The MDAS score was significantly higher in females (P<0.0001) and in patients with previous distressing experiences in medical and/or dental settings (P<0.0001); the correlation with age (P=0.01) and frequency on visiting the dentist (P=0.02) were also significant. CONCLUSIONS The patients' selection (oral surgery only) may be a limit of the study, which might not provide an estimation of anxiety prevalence in the general dental population; however our result agree with those of studies performed in other Countries in the generic population, suggesting the absence of major differences with respect to the surgical setting and show the reliability and manageability of the Italian version of MDAS.

Abstract
This clinical report describes a case of rhinorrhea that arose after surgical intervention of partial maxillary resection and obturator prosthesis positioning. Ultimately, the diagnosis was that rhinorrhea was induced by mechanical irritation of the nasal mucosa determined by the nasal part of the obturator prosthesis. The differential diagnosis of nasal irritation, vasomotor rhinitis, gustatory rhinorrhea are presented and discussed, as well as the technical notes and measures taken to reach the final diagnosis and a satisfactory functional and aesthetic result for the patient.

Abstract
BACKGROUND Anxiety is a relevant but still underscored perioperative problem. The Visual Analogue Scale for Anxiety (VAS-A) seems to be effective, fast and manageable, but has not been fully validated yet. The aim of this study is to validate VAS-A comparing it to, Corah's Dental Anxiety Scale (CDAS) Spielberger's State Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI). METHODS One hundred consecutive patients (38 males and 62 females, median age 49 years) submitted to oral surgery filled out the VAS-A, CDAS, STAI forms Y1 and Y2, and BDI at preoperative examination; the order of administration of tests was randomized. RESULTS VAS-A score was significantly correlated to CDAS (P<0.0001), STAI-Y1 (P<0.0001), STAI-Y2 (P<0.002) but not to BDI (P=0.18). ROC curve analysis suggested VAS-A equal to 46 mm as threshold for anxiety when using STAI Y1 equal to 40 as reference cutoff. CONCLUSION Our study confirms that VAS-A is a reliable indicator of preoperative anxiety and may detect patients with depressive symptoms also. Values of VAS-A around 50 mm are a reliable threshold for a clinically meaningful level of preoperative anxiety.

Abstract
AIM The aim of this paper was to determine whether the use of midazolam is a better technique than the use of diazepam, in relation with the definition of conscious sedation in dentistry. METHODS Eighty-eight patients undergoing oral surgery were divided into 2 groups in which the sedation was randomly achieved with equipotent cumulative doses of diazepam and midazolam, up to a maximum dose of 8 and 4 mg respectively. Patient's tranquillity was assessed after every dose, using a visual analogue score to ten points and the sedation was evaluated as mild, moderate or deep. Blood pressure, heart rate and SpO2 were also recorded. Psychomotor conditions, by Newman test, and the incidence of amnesia and the patient's satisfaction, by telephone interview, were both evaluated. RESULTS The number of patients who reached maximum subjective tranquillity was greater already after the third dose of diazepam. The average scores of tranquillity were higher after diazepam. Patients treated with diazepam experienced a higher incidence of mild sedation, patients treated with midazolam a higher incidence of moderate and deep sedation. In patients treated with midazolam blood pressure, heart rate and SpO2 were lower. Postoperative recovery was similar in the 2 groups. After midazolam patients experienced greater amnesia for local anesthesia and drowsiness. Satisfaction was high with both treatments. CONCLUSION The study shows that sedation with diazepam is more in line with the definition of conscious sedation in dentistry. Diazepam guarantees the persistence of consciousness and maximum subjective tranquillity levels. The recovery and satisfaction were comparable in the 2 groups.

Abstract
BACKGROUND The pharmacologic treatment of migraine still remains below the expectations. The aim of this study is to compare the effectiveness of traditional acupuncture and valproic acid in migraine prophylaxis. METHODS A prospective, controlled study was performed in 100 patients affected by migraine without aura lasting for over one year. The patients were stratified for sex and randomly divided into two groups of 50 patients each. Patients belonging to Group A (acupuncture) were submitted to 20 sessions of acupuncture, while patients belonging to Group V valproate) were administered Valproic acid (Depakin Chrono®) at a dose of 600 mg/day; 10 mg Rizatriptan wafers were allowed as needed to treat the attacks. The Midas Index (MI) and pain intensity (PI, by VAS) were recorded before treatment (T0), at three (T1) and six (T2) months; a six-point scale Pain Relief score (PRS), the Rizatriptan intake and adverse events were recorded at T1 and T2. RESULTS Eighty-two out of 100 patients completed the study (9 dropouts in each group). In both groups the MI improved at T1 and T2 (P<0.0001). Pain intensity was better at T1 in group V (P<0.0001), but PI and PRS (P=0.02) as well as rizatriptan intake (P=0.001) were better in group A at T2. The rate of adverse events was 47.8% in group V and 0% in group A. CONCLUSION Our data show a lower pain intensity and lower Rizatriptan intake at six-months follow-up with no adverse events in acupuncture patients compared to those treated with valproic acid.

Abstract
AIM Bispectral Index Score (BIS) is an objective tool to assess sedation depth. Benzodiazepines have different pharmacological profiles and diazepam may be safer than midazolam in this setting. The aim of this study was to compare BIS values observed during anxiolysis after diazepam versus sedation after midazolam. METHODS Thirty-six patients were randomly assigned to 3 groups: group 1 was treated with i.v. diazepam, groups 2 and 3 with iv midazolam 1 and 3 mg, respectively. Sedation was monitored clinically and by means of BIS. BIS values were evaluated as area under the curve (AUC) and compared by variance analysis. The statistical comparison of other data was performed by variance analysis or, alternatively, the χ2 according to Yates. The statistical significance was indicated by P values <0.05. RESULTS AUC values were significantly lower after midazolam when compared to AUC values registered in diazepam treated patients; 22.6% of the group 3 patients showed BIS values <80, versus 0.4% of group 1 patients. CONCLUSION Diazepam has a safer profile, with BIS values and clinical conditions according to the definition of minimal and/or moderate sedation. Diazepam represents the safer drug for anxiety management in dentistry, because regularly produces a state of sedation during which verbal contact with the patient is maintained and carry a margin of safety wide enough to render loss of consciousness unlikely.

Abstract
Anxiety is a relevant problem in dental practice. The Visual Analogue Scale for Anxiety (VAS-A), introduced in dentistry in 1988, has not yet been validated in large series. The aim of this study is to check VAS-A effectiveness in more than 1000 patients submitted to implantology. The VAS-A and the Dental Anxiety Scale (DAS) were administered preoperatively to 1114 patients (459 males and 655 females, age 54.7 ± 13.1 years). Statistical analysis was conducted with Pearson correlation coefficient, the receiver operating characteristic (ROC) curve, and McNemar tests. A close correlation between DAS and VAS-A was found (r = 0.57, P < .0001); the VAS-A thresholds of dental anxiety and phobia were 5.1 and 7.0 cm, respectively. Despite a significant concordance of tests in 800 cases (72%), disagreement was found in the remaining 314 cases (28%), and low DAS was associated with high VAS-A (230 cases) or vice versa (84 cases). Our study confirms that VAS-A is a simple, sensitive, fast, and reliable tool in dental anxiety assessment. The rate of disagreement between VAS-A and DAS is probably due to different test sensitivities to different components of dental anxiety. VAS-A can be used effectively in the assessment of dental patients, using the values of 5.1 cm and 7.0 cm as cutoff values for anxiety and phobia, respectively.

Abstract
AIM The aim was to compare the efficacy of Kenneth Reed and Gow-Gates inferior alveolar nerve blocks when performed by an inexperienced operator. METHODS A group of 60 patients was randomised into two groups. One group had the Kenneth Reed technique used to administer an inferior alveolar nerve block whilst the other received the Gow-Gates technique. The efficacy of nerve block produced was evaluated both clinically and by electric pulp tester. MRI examination was undertaken to determine the spread of local anaesthetic. RESULTS There were no significant differences in success rate of anaesthesia between groups. The failure rate for the Gow-Gates technique was 16.6%, whilst the failure rate for the Kenneth Reed technique was 23.3%. Time to onset was less with the Kenneth Reed technique. MRI examination showed the solution was more widely distributed after the Kenneth Reed block had been used. CONCLUSIONS Our research has demonstrated that the Kenneth Reed technique is equally effective at producing anaesthesia of the inferior alveolar nerve. Compared with conventional techniques there is a lower incidence of positive aspiration and potential for lower morbidity as the local anaesthetic is deposited further from the neurovascular bundle than when deposited near the mandibular foramen as in most conventional Inferior Alveolar Nerve Block techniques.

Abstract
AIM The research regards information on anesthesia to patients undergoing oral surgery. Every patient evaluated the information received at the end of the preoperative visit and in the postoperative period. METHODS One hundred-fifty dental patients were asked about the most appreciated information received in the preoperative visit on the anxiolytic technique, local anesthesia and treatment of the perioperative pain. Afterwards the patients had to report on their reaction to the content of the preoperative visit and information quality. On a phone interview they had to evaluate their appreciation of the anxiolytic technique, their perception during loco-regional anesthesia and incidence of pain and edema. RESULTS The most appreciated details were those on the intervention, pharmacologic treatment, postoperative complicances, postoperative pain and operative competence; less appreciated were those on loco-regional anesthesia, duration of the intervention, anxiolytic techniques, hospital reception and permanence in the hospital. Ninety-eight percent of the patients considered to have been adequately informed on a context judged to be extraordinary (99.3%), 96.6% indicated the information as necessary, 98.6% appreciated the treatment of the intraoperative and postoperative (99.3%) pain and 99.3% the anxiolytic treatment. On the telephone interview, 100% of patients expressed satisfaction for the experienced intraoperative tranquillity, 91.3% complained for not having received in the past a similar preoperative visit, 99.3% wished a diffused application of the information. The loco-regional anesthesia was associated to psychological detachment in 84% of the cases and the incidence of postoperative pain was of 36%. CONCLUSION The information on the anxiolytic techniques, loco-regional anesthesia, treatment of perioperative pain and postoperative distress was enthusiastically accepted and albeit initially induced feelings of astonishment resulted to be appreciated and preferred in the whole of the patients.

Abstract
OBJECTIVE Patients with carpal tunnel syndrome (CTS) complain of motor symptoms. The study is aimed to understand which features are associated with the presence of motor symptoms in CTS. METHODS We recruited 282 consecutive CTS patients. After selection, 129 patients (203 hands) were included. Patients were asked about the presence and severity of hand weakness (HW) and hand clumsiness (HC). They underwent a self-administered questionnaire on symptoms, clinical evaluation and neurographic study. Quantitative sensory testing (QST) was performed on the patients with unilateral right CTS. RESULTS HW and HC may be found in 56 % and 48 % of CTS hands, respectively. HW was related to the severity of sensory symptoms (pain, numbness and tingling) but not to clinical-neurographic measures of median nerve involvement. HC was related to the severity of sensory symptoms and to the clinical-neurographic signs of motor but not sensory nerve damage. Motor symptoms were significantly more frequent in right hands. QST showed a relationship between the presence and severity of HW and HC and the warm threshold. CONCLUSIONS Motor symptoms may be found in approximately half of CTS hands. Clinical and neurographic signs of median nerve motor damage appear to be poorly correlated to motor symptoms. The factor that can help reconcile the discrepancy between motor symptoms and motor signs is pain. Pain modulation on motor function may take place at various anatomical levels in CTS. Nociceptive C-fibers may be involved in pain-motor interactions finally leading to motor symptoms.

Abstract
Myotonia congenita is a rare disorder caused by a defect in the skeletal muscle chloride channel function, which may cause sustained membrane depolarisation. We report a case regarding a 52-year-old man affected by this muscular pathology and scheduled for shoulder surgery that was performed under sedation and peripheral nerve block. The international literature does not elucidate clear preference toward a particular anaesthesia technique, but we believe that in this setting, regional anaesthesia and complete monitoring should be preferentially utilized when possible. In any case, the anaesthesia plan should be prudent and avoid exposure to known dangerous anaesthetics.

Abstract
AIM The aim of this study was to evaluate the efficacy of Electronic Dental Anaesthesia (EDA) for third molar surgery. METHODS Third molar extraction under regional anaesthesia (inferior alveolar and buccal nerve blocks) was performed in 2 groups of 30 patients each: group 1 = controls, group 2 = EDA treatment. Anxiety and pain level were reported by means of Visual Analogue Scale, postoperative pain description with the McGill Pain Questionnaire. A postoperative phone interview to all patients was made. Computerized randomization was performed; values expressed as mean+/-SD, data comparison evaluated by means of ANOVA and chi squared, statistical significance indicated by P values <0.05. RESULTS Features of the patients and surgical interventions were similar. EDA has determined lower pain level; moreover, the control patients has shown higher values of blood pressure and heart frequency. Phone interview has reported no amnesia about the perioperative events. A smaller number of EDA treated patients has reported pain during needle prick and/or intraoperatively; 80% of the EDA treated patients has reported a good opinion about the treatment, 93% of the patients would repeat the treatment, if needed. CONCLUSION EDA is a complementary analgesic technique for dental surgery. Cardiovascular changes, frequently observed during third molar extraction, were not present in the EDA treated patients. These data confirm that EDA is able to modify the physiologic responses to stressful events, blunting the adrenergic upset, maybe by means of an analgesic action on A, fiber and an increase of endorphins' central level. These results underline that the complementary use of EDA in the third molar extraction may be better than regional anaesthesia alone.

Abstract
A 1-year-old child was scheduled for two stage bilateral clubfoot surgery. Preoperative evaluation was normal and total intravenous anesthesia with a continuous sciatic nerve block was performed. Two months later, before the second clubfoot correction, a hip subluxation was evident suggesting a provisional diagnosis of neuromuscular disease. Anesthesia was identical, except that a femoral nerve block, necessary to permit a diagnostic muscle biopsy was performed. The perioperative course was uneventful but result of the muscular biopsy was surprising in that central core disease was diagnosed. Although congenital myopathies of all grades and severity exist, they are often mild and underestimated. Patients affected by central core disease are considered susceptible to malignant hyperthermia. Because a high prevalence of myopathic changes is reported in children undergoing clubfoot surgery, anesthesiologists must take precautions including a hightened awareness of these events and a high index of suspicion.

Abstract
AIM Despite routine postoperative pain management improves recovery and reduces postoperative morbidity and overall costs, and the availability of a large armamentarium of analgesic techniques and drugs, a significant portion of patients do not receive adequate postoperative pain control. We describe a recovery room (RR) based acute pain service model. METHODS Guidelines on postoperative pain and therapeutic protocols were instituted in January 1999. The analgesic endpoint was a visual analogic scale (VAS) below 4 for all surgical patients for the first 48-72 h. The RR, run by one anesthesiologist and 2 nurses and one assistant, acted as a coordination centre. Discharge from the RR was subject to achieving effective analgesia. Nurses of each ward monitored VAS along with vital signs, administered rescue doses if necessary, and reported to the RR nurse when needed. RR nurses monitored the patient at least twice daily and reported to the anesthesiologist. We have distributed an anonymous questionnaire, within surgical wards, to both surgeons and nurses to evaluate their perception of pain management and of this acute pain service (APS) model. RESULTS VAS was maintained significantly <4. Analgesic drug consumption increased between 1997, 2000 (first year of APS) and 2004. The auditing process confirmed the desire of all professional figures to be informed and involved in acute pain management as part of a coordinated and systematic approach to the surgical patient. CONCLUSION A RR-based APS can effectively act as coordinating centre for acute pain treatment without adjunctive personnel.

Abstract
AIM Aim of this study was to assess by clinical evaluation and by Bispectral Index (BIS) the tranquillizing properties of diazepam injected intravenously, and midazolam by intranasal route according to the body weight in dental patients. METHODS A group of 34 patients undergoing implantology were divided at random into 2 groups of 17. They were evaluated physically, clinically and psychologically. The psychomotor activity was measured by the Newman's test. Preoperative anxiety was treated with chlordemethyldiazepam (CHDDZ) per os, administered before induction of conscious sedation. In the first group, conscious sedation was accomplished by induction with titrated doses of i.v. diazepam, and in the second group with 0.1 mg/kg of intranasal midazolam. BIS values were analysed as Area Under the Curve (AUC). RESULTS The AUC BIS values after CHDDZ presedation were overlapping in both groups. AUC after midazolam decreased after induction of the conscious sedation (P<0.05), during anesthesia (P<0.01) and during intervention (P<0.01) compared to the diazepam treatment. In the midazolam group the BIS values were on average lower than 90, while in the diazepam group they were on average higher than 95 (P<0.01). The psychomotor recovery was more impaired after midazolam. CONCLUSIONS The study shows that nasal route ensures the quick absorption of midazolam as revealed during the first 3 min from drug administration. The depressant effect of midazolam increased as a function of time, reaching the highest levels during intervention. The results suggest that midazolam is endowed with sedative effects which may compromise the state of consciousness of the patient and be incompatible with the definition of conscious sedation in dentistry.

Abstract
BACKGROUND The classic laryngeal mask airway (cLMA) has been demonstrated to be effective for airway management during neonatal resuscitation. However, high airway pressures, when required, cannot be achieved with this device. A neonatal prototype of the LMA-ProSeal (PLMA), which might improve the oropharyngeal leak pressure, has recently been produced. The airway sealing pressures of the cLMA and the PLMA were compared in a neonatal manikin. METHODS A neonatal PLMA and a neonatal cLMA were positioned at random in a neonatal intubation manikin (Neonate Airway Trainer; Laerdal, Norway). A Dräeger pressure controlled ventilator (Dräeger 8000; Dräegerwerk AG, Germany) was connected to the airway tubes and increasing inspiratory pressures (from 10 to 40 cm H2O) of positive pressure ventilation applied. The peak and the mean airway pressures obtained with each device were recorded. RESULTS The airway pressures obtained with PLMA were significantly higher than those obtained with cLMA (p < 0.01) at levels of positive pressure ventilation of 25, 30, 35 and 40 cm H2O. CONCLUSIONS The neonatal PLMA allows higher airway pressure ventilation than the cLMA, in a neonatal intubation manikin. If confirmed clinically, this may have important implications during neonatal resuscitation when high airway pressures are required.

Abstract
OBJECTIVE To investigate the effect of sleep deprivation on corticospinal excitability in patients affected by juvenile myoclonic epilepsy (JME) using different transcranial magnetic stimulation (TMS) parameters. METHODS Ten patients with JME and 10 normal subjects underwent partial sleep deprivation. Motor threshold (MT), motor evoked potential amplitude (MEP), and silent period (SP) were recorded from the thenar eminence (TE) muscles. Short latency intracortical inhibition (SICI) and short latency intracortical facilitation (SICF) were studied using paired magnetic stimulation. TMS was performed before and after sleep deprivation; EEG and TMS were performed simultaneously. RESULTS In patients with JME, sleep deprivation induced a significant decrease in SICI and an increase in SICF, which was associated with increased paroxysmal activity. A significant decrease in the MT was observed. No significant changes in any TMS parameters were noted in normal subjects after sleep deprivation. The F wave was unchanged by sleep deprivation in both control subjects and in patients with JME. CONCLUSIONS In patients with JME, sleep deprivation produces increases in corticospinal excitability in motor areas as measured by different TMS parameters.

Abstract
AIM The aim of this study was to evaluate the effects of sedation with benzodiazepines in a large population of patients undergoing oral surgery and age-related implications. METHODS A group of 1 179 consecutive patients undergoing oral surgery in the Dental Clinic of the University of Padua between 2001 and 2003 was evaluated by analysing their anaesthesiological records. The patients were divided into 5 age groups. All were pre-sedated with chlordemethyldiazepam per os, while induction of maximum subjective tranquillity was obtained with fractionated doses of intravenous diazepam. Arterial pressure (AP), heart rate (HR), anxiety level, pathologies, drugs taken, types of intervention, techniques of loco-regional anaesthesia, immediately preoperative AP and HR and tranquillity, intraoperative AP and HR, data regarding postoperative psychomotor recovery, complications and drugs used for the treatment of perioperative pain, were evaluated in each group. RESULTS Most of the patients (679) were in the 45-64 year-old group. Cardiovascular, respiratory and digestive pathologies proved to be age-dependent. Control AP and HR respectively increased and decreased with age. The doses of chlordemethyldiazepam used induced age-dependent preoperative tranquillity levels. The doses of i.v. diazepam necessary to obtain maximal preoperative subjective tranquillity fell as a function of age. The AP and HR values respectively increased during intervention and decreased in the first hour of intervention. Normal psychomotor recovery was less evident in older patients. The most significant corrective intraoperative interventions consisted of the administration of sublingual hypotensive drugs and in the immediate treatment of some cases of orthostatic hypotension and vaso-vagal syncope. CONCLUSIONS The sedation technique and the antistress procedures employed proved safe and the intra- or postoperative complications almost non-existent. The variations observed in the parameters considered are compatible with the greater age of the treated subjects.

Abstract
Cranial dural arteriovenous fistulas (DAVFs) usually present with non-aggressive symptoms. We here report two patients who presented a peculiar clinical picture related to DAVFs, with focal neurological signs and haemorrhagic (case 1) or ischaemic lesions (case 2) respectively. The clinical and angiographic findings and putative pathophysiological mechanisms are discussed.

Abstract
BACKGROUND The number of children requiring sedation for radiological procedures is increasing. Anaesthesiologists are increasingly involved in giving sedation or general anaesthesia in the rooms of the Radiology Department. This activity is not easy, and can be dangerous. The procedure is often performed on an ambulatory basis, so the child must be alert and discharged rapidly after the procedure. METHODS We reviewed the medical charts of 488 patients in order to evaluate the incidence of complications during deep sedation for diagnostic radiological procedures. The patients were sedated with intravenous thiopental or propofol, or with oral chloral hydrate. All the patients were breathing spontaneously and received only supplemental O(2). RESULTS We found only a few cases of complications, immediately treated without any recourse to tracheal intubation: respiratory failure with arterial desaturation to 94%, regurgitation, vomiting and persistent cough. CONCLUSIONS On the basis of our experience, we believe that deep sedation with endovenous drugs guarantees safety and rapid discharge after the procedure.

Abstract
BACKGROUND AND AIMS In patients with non-insulin dependent diabetes mellitus (T2DM) and associated chronic liver disease, plasma levels of glucose, insulin and triglycerides are high, lipid peroxidation is increased and natural antioxidant reserves are reduced. Thus, we hypothesised that the re-balancing of cell redox levels and amelioration of liver function could result in a better glucose and lipid metabolism. To study this, we assessed the effect of a new oral formulation of an antioxidant agent - silybin-beta-cyclodextrin (named IBI/S) - in patients with chronic alcoholic liver disease and concomitant T2DM. METHODS Sixty outpatients were enrolled in a three-centre, double blind, randomised, IBI/S vs placebo study. Forty-two (21 in the group IBI/S - 135 mg/d silybin per os - and 21 in the placebo group) concluded the 6-month treatment period. The efficacy parameters included fasting and mean daily plasma glucose levels, glycosylated hemoglobin (HbA1c), basal, stimulated C-peptide and insulin levels, total-, HDL-cholesterol and triglycerides levels in addition to conventional liver function tests. Insulin sensitivity was estimated by HOMA-IR. Malondialdehyde (MDA) was also measured before and after treatment as an index of oxidative stress. RESULTS Fasting blood glucose levels, which were similar at baseline in IBI/S group and in the placebo group (173.9 mg/dl and 177.1 mg/dl, respectively), decreased to 148.4 mg/dl (-14.7% vs baseline; p = 0.03) in the IBI/S group while they were virtually unchanged in the placebo group. The comparison between the groups at mo 6 (T6) also showed a significant reduction of glucose levels in the IBI/S group (p = 0.03). The same trend was observed in mean daily blood glucose levels, HbA1c and HOMA-IR, although differences were not significant. Basal and stimulated C-peptide values showed that only a few changes had occured in both groups. Such results indicate that insulin secretion was virtually unaffected, as confirmed also by the insulinemia data. Plasma triglycerides concentrations dropped from a baseline value of 186 mg/dl to 111 mg/dl (T6) in the IBI/S group, with significant differences at all instances with respect to baseline values. By contrast, triglycerides increased from 159 mg/dl at entry to 185 mg/dl (T6) in the placebo group. The difference between the groups at T6 was highly significant (p < 0.01). Total and HDL cholesterol as well as liver function tests did not change significantly during the study in both groups. MDA decreased significantly only in the group receiving IBI/S. No clinically relevant side effects were observed in either group. CONCLUSIONS Oral administration silybin-beta-cyclodextrin in patients with T2DM and compensated chronic alcoholic liver disease causes a significant decrease in both glucose and triglyceride plasma levels. These effects may be due to the recovery of energy substrates, consistent with a reduced lipid peroxidation and an improved insulin activity.

Abstract
OBJECTIVE Transcranial magnetic stimulation (TMS) has allowed investigators to study intracortical inhibition and facilitation and sensorimotor integration in motor disorders and epilepsy. The authors used TMS to elucidate the pathophysiology of reflex myoclonus with giant somatosensory evoked potentials (SEP). METHODS The authors studied four patients with progressive myoclonic epilepsy. All patients had giant SEP elicited by mixed and digital nerve stimulation. They studied the response to paired-pulse TMS at interstimulus intervals (ISI) ranging from 1 to 15 ms and the conditioning effect of digital electrical stimulation at ISI ranging from 10 to 100 ms on the motor evoked potential amplitude to TMS. RESULTS Digital stimulation markedly facilitated conditioned motor evoked potentials at ISI ranging from 25 to 40 ms in all patients. This pattern was significantly different from the inhibition observed in controls (n = 12) at the same ISI. In the patients, paired-pulse TMS showed a decrease in intracortical inhibition in the motor cortex in comparison with controls. CONCLUSIONS These findings suggest cortical and subcortical components of abnormal sensorimotor integration in addition to hyperexcitability of the sensory and motor cortex in our myoclonic patients.

Abstract
The aim of this study was to elucidate sensorimotor integration in human hand motor areas, its time course, somatotopy and the interaction of sensory fields arising from two different fingers. We studied the influence of different intensities of electrical digital stimulation of two different fingers on motor-evoked potentials elicited in hand muscles by transcranial magnetic stimulation (TMS). Single conditioning electrical stimuli were applied to the right second (D2) and fifth fingers (D5) individually and also to both fingers (D2+D5) simultaneously in six normal volunteers. Magnetic tests, adjusted to produce a response in the abductor digiti minimi muscle of the right hand, were delivered using a circular and a focal coil. The digital stimuli were delivered to the finger at the sensory threshold (ST), at 3 and 5 times the ST, and over the pain threshold at interstimulus intervals (ISIs) ranging from 10 to 100 ms. In order to define the anatomical level of the sensorimotor interactions, the effect of the digital stimulation on TMS was compared to the effect on transcranial electrical stimulation. When the peripheral stimulation was delivered at the ST a small inhibitory effect was found only when stimulating both fingers. At 3 times the ST we detected a topographic distribution of motor-evoked potential inhibition, which partially disappeared at higher intensity (5 times the ST); two types of convergence effects took place at different ISIs. When conditioning stimuli were painful, somatotopy and convergence were lost. Sensorimotor integration shows somatotopy and interaction of afferents at different sites. The intensity of the conditioning stimulus plays an important role in topography and sensory convergence. The importance of these mechanisms in physiology and physiopathology is discussed.

Abstract
The effect of sleep deprivation on human motor cortical excitability was investigated by evaluating the changes in motor evoked potentials from the thenar eminence muscles of the right hand in seven subjects. Motor threshold, motor evoked potential amplitude, silent period, intracortical inhibition, intracortical facilitation and F wave were studied. Recordings were performed every 6 h during the day-time (from 09.00 to 21.00 h) and every 3 h during the night-time (from 21.00 to 09.00 h). Significant increases in motor threshold, intracortical inhibition and silent period were noted in the recordings during the night associated with a return to baseline values in the morning. No significant changes were observed in any of the other parameters. Enhancement of intracortical motor inhibition is suggested to explain the effect of sleep deprivation.

Abstract
Although non-insulin-dependent diabetes mellitus (NIDDM) is considered a major cause of death, the role of some independent risk factors in diabetic patients is under debate. In fact the prognosis of NIDDM diabetes varies considerably in relation to the individual risk pattern, and the different studies are not directly comparable because of differences in size, age and geography of the samples, and type of statistical analysis. The aim of the study is to identify the independent predictors of mortality in a cohort of subjects with NIDDM, and to verify whether the relative risk (RR) of cardiovascular mortality is different in comparison to that of coeval non-diabetic subjects from a general population. The study includes 683 patients with NIDDM from the Northern Italian town of Pordenone, followed up for 6 years and age- and sex-matched to 683 non-diabetic subjects from a Northern Italian general population. When the two cohorts were compared, NIDDM turned out to be a strong risk factor for cardiovascular mortality (RR: 2.67). Age, coronary artery disease (RR: 1.78), arterial hypertension (RR: 1.39), macro- (RR: 2.97) and microalbuminuria (RR: 2.01) were independent predictors of cardiovascular mortality in the diabetics. In conclusion, survival of diabetic patients is worse than that of non-diabetic coeval subjects. Only few items are able to predict cardiovascular mortality in the diabetics, namely age, hypertension, CAD, macro- and microalbuminuria.

Abstract
Several recent reports suggest the possibility of monitoring pharmacological effects on brain excitability through transcranial magnetic stimulation (TMS). In these studies, paired magnetic stimulation has been used in normal subjects and on patients who were taking different antiepileptic drugs. The aim of our study was to investigate motor area excitability on depressed patients after intravenous administration of a single dose of clomipramine, a tricyclic antidepressant. Motor cortex excitability was studied by single and paired transcranial magnetic stimulation (TMS) before and after 4, 8 and 24 h from intravenous administration of 25 mg of clomipramine. Cortical excitability was measured using different TMS parameters: motor threshold (MT), motor evoked potential (MEP) amplitude, duration of cortical silent period (CSP), intracortical inhibition (ICI) and intracortical facilitation (ICF). Spinal excitability and peripheral nerve conduction was measured by F response and M wave. A temporary but significant increase of motor threshold and intracortical inhibition and a decrease of intracortical facilitation were observed 4 h following drug administration. MEP amplitude, cortical silent period, F response and M wave were not significantly affected by drug injection. Our findings suggest that a single intravenous dose of clomipramine can exert a significant but transitory suppression of motor cortex excitability in depressed patients. TMS represents a useful research tool in assessing the effects of motor cortical excitability of neuropsychiatric drugs used in psychiatric disease.

Abstract
PURPOSE We investigated 15 patients with juvenile myoclonic epilepsy (JME) by subjecting them to single and paired transcranial magnetic stimulation to test the hypothesis that motor cortical inhibition may be abnormal in this form of benign epilepsy. METHODS Different conditioning paradigms of paired transcranial magnetic stimulation were used with interstimulus intervals (ISIs) of varying lengths (1 to 400 milliseconds) to investigate changes in balance between excitatory and inhibitory intracortical circuits. RESULTS Motor evoked potential (MEP) inhibition at ISIs of 1 to 4 milliseconds was significantly lower in JME patients than in age-matched healthy controls (p < 0.001), whereas no significant differences in MEP inhibition were noted at long ISIs (100 to 150 milliseconds). This pattern was observed in both hemispheres in seven of seven patients studied bilaterally and was present in both treated and untreated patients. There were no group differences between JME patients and controls in intracortical facilitation, motor threshold, MEP amplitude, and cortical silent period. CONCLUSIONS We documented a different pattern of MEP inhibition in JME patients, suggesting impaired functioning of inhibitory interneuronal circuits, which may account for the hyperexcitability of the motor system in this form of epilepsy.

Abstract
OBJECTIVES Among the different kinds of rolandic epilepsy there is a form of benign epilepsy with centrotemporal spikes (BECT) presenting the peculiar characteristic of evoking rolandic paroxysmal activity, characterized by a spike followed by a slow wave, using electrical stimulation of the fingers. METHODS We evaluated 7 patients suffering from BECT presenting evoked scalp activity by electrical stimulation of the fingers of the hand. Electrical stimulation was performed using a pair of ring electrodes applied to the thumb. The motor evoked potentials (MEPs) were elicited in hand muscles by transcranial magnetic stimulation (TMS) and were conditioned by the same electrical digital stimulation producing the evoked spikes at interstimulus intervals ranging from 10 to 200 ms. RESULTS Digital stimulation in epileptic patients produced an increase in MEP amplitude substantially above the normal ranges. MEP facilitation showed a time course overlapping the ascending phase and peak of the evoked spike, whereas no significant MEP changes were found during the early positive peak and the descending phase of the spike, or during the following slow wave. CONCLUSIONS Several considerations support the hypothesis that the short-lasting M1 facilitation is related to the spread of an abnormal hypersynchronous discharge of the S1 neurones to functionally related motor areas via cortico-cortical connections.

Abstract
OBJECTIVE To assess the efficacy and diagnostic value of GnRH agonist (GnRH-a) therapy in cases of hidden sciatic nerve endometriosis. DESIGN Case report. SETTING Academic tertiary referral center for endometriosis treatment. PATIENT(S) Three patients with cyclic, catamenial sciatica associated with pelvic endometriosis who had electromyographic evidence of sciatic nerve damage but negative computed tomography and magnetic resonance imaging findings. INTERVENTION(S) Monthly administration of the GnRH-a leuprolide acetate plus daily transdermal E2 (25 microg). MAIN OUTCOME MEASURE(S) Relief of pain symptoms and improvement in motor function. RESULT(S) All three patients had clear decreases in pain and partial amelioration of claudication. CONCLUSION(S) Endometriosis of the sciatic nerve may be hard to diagnose with the use of current imaging techniques but may be proved by clinical response to GnRH analogue treatment and may be more frequent than previously thought.
