Abstract
BACKGROUND Temporomandibular disorders (TMDs) represent a common chronic complaint, which includes myofascial pain (MP). Although several therapeutical options have been proposed to control bruxism-related muscle hyperactivity, there is not enough evidence to define a standard approach. The present article describes the case of a 14-year old male patient with a history of painful mandibular close lock. CASE REPORT The patient was diagnosed with persistent myofascial pain in the left masseter, bilateral disc displacement with reduction, and retrodiscitis and capsulitis in the left temporomandibular joint. Awake and sleep bruxism were also present. Since first line treatments failed in managing the disorders, injections of onabotulinum toxin (BoNT-A ) were performed. After one month the pain decreased significantly and the jaw movements were restored. The patient was recommended to avoid hard and/or rubbery food, wide movements of the jaws and teeth clenching and to wear orthodontic appliance during the night since the joint damage was moderate. We report the 7-year follow-up demonstrating the long-term efficacy of a single injection of onabotulinum toxin in masseters and temporalis muscles in order to treat masticatory pain and dysfunctions. CONCLUSION The authors suggest that BoNT-A could be an optimum treatment for persistent MP and bruxism in young adolescents when first-line therapies fail.

Abstract
Abstract
Introduction
Life–threatening ventricular arrhythmias secondary to chest trauma without structural cardiac damage (i.e. commotio cordis [CC]) are a rare but dramatic cause of sudden cardiac death. We present a case of fast ventricular tachycardia (VT) induced by blunt chest trauma in a healthy man during sports activity.
Case Presentation
A 22–year–old man, competitive soccer player, was admitted to our hospital for VT. A few hours before admission, after a heavy ball impact in the chest during a soccer match, he suddenly reported fast and regular palpitation with lightheadedness and dyspnea, without loss of consciousness. The emergency medical service was activated, and the evaluation revealed a hemodynamically tolerated monomorphic VT with a rate of almost 285 bpm (Fig.A). Amiodaron infusion was ineffective and sinus rhythm (SR) was restored by electrical cardioversion. At the time of admission, he was asymptomatic. Familiar history, past medical history and physical examination were unremarkable. ECG revealed regular SR, with minimal right bundle branch conduction delay (Fig.B). Blood samples showed normal blood cells count, electrolyte concentrations and liver, kidney, and thyroid function; seriate high sensitivity troponin I determinations were negative. Echocardiography and cardiac magnetic resonance showed normal findings. Computed tomography angiography excluded coronary anomalies. Exercise test revealed no signs of cardiac ischemia and no effort–induced arrhythmias. The fluoroscopy–free unipolar and bipolar voltage maps showed normal electrograms throughout the right ventricle (Fig.C). No sustained arrhythmias were induced by programmed ventricular stimulation. The patient was then discharged with the indication to cardiology follow–up and the advice to avoid contact sports activities.
Discussion
VT is a rare presentation of CC. It has been proposed that CC occurs when a chest strike timed at the upstroke of the T–wave causes both ventricular depolarization trigger and altered dispersion of repolarization, mainly via activation of KATP channels. In the absence of structural heart disease (SHD), the usual presenting rhythm is ventricular fibrillation and there are no accepted mechanisms to explain monomorphic VT in this context. Some authors reported monomorphic VT after chest trauma as the first manifestation of arrhythmogenic cardiomyopathy. Therefore, a careful follow–up will be needed to exclude future development of SHD in this patient.

Abstract
Abstract
Introduction
Percutaneous left stellate ganglion block (PLSGB) has been reported as a safety and effective procedure for the management of refractory arrhythmic storm (AS). In this report we present a case of a man with refractory AS effectively treated with PLSGB, subsequently candidate for an invasive procedure potentially associated with adrenergic stimulation and propose the use of this technique as pre–treatment strategy in this clinical setting.
Case presentation
A 57–year–old man was admitted to our hospital for AS. Past medical history revealed that two years earlier he had been treated with primary percutaneous coronary intervention for ST–segment elevation myocardial infarction. Four months before admission he underwent coronary artery bypass graft surgery with concomitant mechanical mitral valve replacement, closure of an interventricular defect and, considering the severe left ventricular disfunction, he was implanted with an automatic defibrillator in primary prevention. At the time of admission, he was treated with lidocaine infusion with remission of arrhythmic events. Comprehensive diagnostic workup revealed no overt triggers for AS. Five days after admission, the patient experienced recurrence of ventricular arrhythmias (VA), refractory to amiodarone, lidocaine, and magnesium infusion, increased pacing rate, and sedation with dexmedetomidine. PLSGB was then attempted with the injection of lidocaine and ropivacaine using an anatomical approach with complete remission of arrhythmic events. After a week free from VAs, a new AS was observed and PLSGB was repeated using the same modality with complete arrhythmic resolution. Considering the advanced heart failure, the patient was candidate to heart transplantation (HT) and, before undergoing gastro– and colonoscopy required for inclusion in the HT program, with the aim to reduce the risk of VA recurrences triggered by potential adrenergic stimulation, we pre–treated the patient with PLSGB using only ropivacaine, with successful induction of temporary Horner syndrome (Fig. A). The endoscopy procedures were performed successfully with no VA events and the patient was then discharged waiting for HT.
Conclusion
We propose the use of PLSGB as a pre–treatment strategy for patients at high–risk of VAs who are candidates for invasive procedures potentially associated with adrenergic stimulation. This report could be hypotheses–generating for further studies on this topic.

Abstract
PURPOSE A large proportion of patients with cancer suffer from breakthrough cancer pain (BTcP). Several unmet clinical needs concerning BTcP treatment, such as optimal opioid dosages, are being investigated. In this analysis the hypothesis, we explore with an unsupervised learning algorithm whether distinct subtypes of BTcP exist and whether they can provide new insights into clinical practice. METHODS Partitioning around a k-medoids algorithm on a large data set of patients with BTcP, previously collected by the Italian Oncologic Pain Survey group, was used to identify possible subgroups of BTcP. Resulting clusters were analyzed in terms of BTcP therapy satisfaction, clinical features, and use of basal pain and rapid-onset opioids. Opioid dosages were converted to a unique scale and the BTcP opioids-to-basal pain opioids ratio was calculated for each patient. We used polynomial logistic regression to catch nonlinear relationships between therapy satisfaction and opioid use. RESULTS Our algorithm identified 12 distinct BTcP clusters. Optimal BTcP opioids-to-basal pain opioids ratios differed across the clusters, ranging from 15% to 50%. The majority of clusters were linked to a peculiar association of certain drugs with therapy satisfaction or dissatisfaction. A free online tool was created for new patients’ cluster computation to validate these clusters in future studies and provide handy indications for personalized BTcP therapy. CONCLUSION This work proposes a classification for BTcP and identifies subgroups of patients with unique efficacy of different pain medications. This work supports the theory that the optimal dose of BTcP opioids depends on the dose of basal opioids and identifies novel values that are possibly useful for future trials. These results will allow us to target BTcP therapy on the basis of patient characteristics and to define a precision medicine strategy also for supportive care.

Abstract
To improve patient care and help clinical research, the Neuropathic Pain Special Interest Group of the Italian Neurological Society appointed a task force to elaborate a consensus statement on pharmacoresistant neuropathic pain. The task force included 19 experts in neuropathic pain. These experts participated in a Delphi survey consisting of three consecutive rounds of questions and a face-to-face meeting, designed to achieve a consensus definition of pharmacoresistant neuropathic pain. In the three rounds of questions, the participants identified and described the main distinguishing features of pharmacoresistance. In the face-to-face meeting the participants discussed the clinical features determining pharmacoresistance. They finally agreed that neuropathic pain is pharmacoresistant when "the patient does not reach the 50% reduction of pain or an improvement of at least 2 points in the Patient Global Impression of Change, having used all drug classes indicated as first, second, or third line in the most recent and widely agreed international guidelines, for at least 1 month after titration to the highest tolerable dose." Our consensus statement might be useful for identifying eligible patients for invasive treatments, and selecting patients in pharmacological trials, thus improving patient care and helping clinical research.

Abstract
Preclinical Research Δ9 -Tetrahydrocannabinol (THC) is a hydrophobic compound that has a potent antinociceptive effect in animals after intrathecal (IT) or intracerebroventricular (ICV) administration. The lack of a suitable solvent precludes its IT administration in humans. 2-Hydroxypropyl-β-cyclodextrin (HPβCD) increases the water solubility of hydrophobic drugs and is approved for IT administration in humans. To investigate whether HPβCD might be a suitable carrier for ICV administration of THC in rats, two formulations containing THC complexed with HPβCD (30 and 135 μg of THC per animal) and vehicle were administered to Wistar rats. The antinociceptive effect (using the tail flick test), locomotor activity, and body temperature were evaluated. ICV injection of 135 μg of THC/HPβCD complex increased tail flick latency, reduced locomotor activity, and had a dual effect on body temperature. The 30 μg THC/HPβCD formulation only produced a hyperthermic effect. All animals appeared healthy, with no difference between the groups. These results were similar to those obtained in other preclinical studies in which THC was administered centrally using solvents that are unsuitable for IT administration in humans because of their toxicity. Our findings suggest that HPβCD may be a useful carrier for IT administration of THC in humans. Drug Dev Res 78 : 411-419, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
Introduction An ongoing national multicenter survey [Italian Oncologic Pain multiSetting Multicentric Survey (IOPS-MS)] is evaluating the characteristics of breakthrough cancer pain (BTP) in different clinical settings. Preliminary data from the first 1500 cancer patients with BTP enrolled in this study are presented here. Methods Thirty-two clinical centers are involved in the survey. A diagnosis of BTP was performed by a standard algorithm. Epidemiological data, Karnofsky index, stage of disease, presence and sites of metastases, ongoing oncologic treatment, and characteristics of background pain and BTP and their treatments were recorded. Background pain and BTP intensity were measured. Patients were also questioned about BTP predictability, BTP onset (≤10 or >10 min), BTP duration, background and BTP medications and their doses, time to meaningful pain relief after BTP medication, and satisfaction with BTP medication. The occurrence of adverse reactions was also assessed, as well as mucosal toxicity. Results Background pain was well controlled with opioid treatment (numerical rating scale 3.0 ± 1.1). Patients reported 2.5 ± 1.6 BTP episodes/day with a mean intensity of 7.5 ± 1.4 and duration of 43 ± 40 min; 977 patients (65.1%) reported non-predictable BTP, and 1076 patients (71.7%) reported a rapid onset of BTP (≤10 min). Higher patient satisfaction was reported by patients treated with fast onset opioids. Conclusions These preliminary data underline that the standard algorithm used is a valid tool for a proper diagnosis of BTP in cancer patients. Moreover, rapid relief of pain is crucial for patients’ satisfaction. The final IOPS-MS data are necessary to understand relationships between BTP characteristics and other clinical variables in oncologic patients. Funding Molteni Farmaceutici, Italy.

Abstract
Clinical management of breakthrough cancer
pain (BTcP) is still not satisfactory despite the availability of effective pharmacological agents. This is in part linked to the lack of clarity regarding certain essential aspects of BTcP, including terminology, definition, epidemiology and assessment. Other barriers to effective management include a widespread prejudice among doctors and patients concerning the use of opioids, and inadequate assessment of pain severity, resulting in the prescription of ineffective drugs or doses. This review presents an overview of the appropriate and inappropriate actions to take in the diagnosis and treatment of BTcP, as determined by a panel of experts in the field. The ultimate aim is to provide a practical contribution to the unresolved issues in the management of BTcP. Five ‘things to do’ and five ‘things not to do’ in the diagnosis and treatment of BTcP are proposed, and evidence supporting said recommendations are described. It is the duty of all healthcare workers involved in managing cancer patients to be mindful of the possibility of BTcP occurrence and not to underestimate its severity. It is vital that all the necessary steps are carried out to establish an accurate and timely diagnosis, principally by establishing effective communication with the patient, the main information source. It is crucial that BTcP is treated with an effective pharmacological regimen and drug(s), dose and administration route prescribed are designed to suit the particular type of pain and importantly the individual needs of the patient.

Abstract
Until 2010 pain management in Italy was only partially covered and no structural and qualitative mapping had ever been realized. The VEDUTA project was designed to provide a tool to unite pain therapists in national cooperation. Quantitative questionnaires and narrative plots were sent to 350 Italian specialists; 184 therapists completed the first section and 87 also wrote their stories. Narratives were analyzed through transactional analysis and emotional intelligence. Overall, results show that a patient-centered approach is common in daily practice, but that bureaucracy is endangering quality of care. This cultural analysis, through both the application of quantitative assessment and narrative plots, provides a useful tool to improve those aspects of the system detrimental to the appropriate management of pain in Italy.

Abstract
Fibromyalgia is a pain disorder associated with frequent comorbid mood, anxiety, and sleep disorders. Despite the frequent use of a complex, poly-drug pharmacotherapy, treatment for fibromyalgia is of limited efficacy. Oxytocin has been reported to reduce the severity of pain, anxiety, and depression, and improve the quality of sleep, suggesting that it may be useful to treat fibromyalgia. To evaluate this hypothesis, 14 women affected by fibromyalgia and comorbid disorders, assuming a complex pharmacotherapy, were enrolled in a double-blind, crossover, randomized trial to receive oxytocin and placebo nasal spray daily for 3 weeks for each treatment. Order of treatment (placebo-oxytocin or oxytocin-placebo) was randomly assigned. Patients were visited once a week. At each visit, the following instruments were administered: an adverse drug reaction record card, Visual Analog Scale of Pain Intensity, Spielberger State Anxiety Inventory, Zung Self-rating Depression Scale, and SF-12. Women self-registered painkiller assumption, pain severity, and quality of sleep in a diary. Unlikely, oxytocin nasal spray (80 IU a day) did not induce positive therapeutic effects but resulted to be safe, devoid of toxicity, and easy to handle.

Abstract
BACKGROUND In male patients suffering from chronic pain, opioid administration induces severe hypogonadism, leading to impaired physical and psychological conditions such as fatigue, anaemia and depression. Hormone replacement therapy is rarely considered for these hypogonadic patients, notwithstanding the various pharmacological solutions available. METHODS To treat hypogonadism and to evaluate the consequent endocrine, physical and psychological changes in male chronic pain patients treated with morphine (epidural route), we tested the administration of testosterone via a gel formulation for one year. Hormonal (total testosterone, estradiol, free testosterone, DHT, cortisol), pain (VAS and other pain questionnaires), andrological (Ageing Males' Symptoms Scale-AMS) and psychological (POMS, CES-D and SF-36) parameters were evaluated at baseline (T0) and after 3, 6 and 12 months (T3, T6, T12 respectively). RESULTS The daily administration of testosterone increased total and free testosterone and DHT at T3, and the levels remained high until T12. Pain rating indexes (QUID) progressively improved from T3 to T12 while the other pain parameters (VAS, Area%) remained unchanged. The AMS sexual dimension and SF-36 Mental Index displayed a significant improvement over time. CONCLUSIONS In conclusion, our results suggest that a constant, long-term supply of testosterone can induce a general improvement of the male chronic pain patient's quality of life, an important clinical aspect of pain management.

Abstract
Although many patients with multiple sclerosis (MS) complain of trigeminal neuralgia (TN), its cause and mechanisms are still debatable. In a multicentre controlled study, we collected 130 patients with MS: 50 patients with TN, 30 patients with trigeminal sensory disturbances other than TN (ongoing pain, dysaesthesia, or hypoesthesia), and 50 control patients. All patients underwent pain assessment, trigeminal reflex testing, and dedicated MRI scans. The MRI scans were imported and normalised into a voxel-based, 3D brainstem model that allows spatial statistical analysis. The onset ages of MS and trigeminal symptoms were significantly older in the TN group. The frequency histogram of onset age for the TN group showed that many patients fell in the age range of classic TN. Most patients in TN and non-TN groups had abnormal trigeminal reflexes. In the TN group, 3D brainstem analysis showed an area of strong probability of lesion (P<0.0001) centred on the intrapontine trigeminal primary afferents. In the non-TN group, brainstem lesions were more scattered, with the highest probability for lesions (P<0.001) in a region involving the subnucleus oralis of the spinal trigeminal complex. We conclude that the most likely cause of MS-related TN is a pontine plaque damaging the primary afferents. Nevertheless, in some patients a neurovascular contact may act as a concurring mechanism. The other sensory disturbances, including ongoing pain and dysaesthesia, may arise from damage to the second-order neurons in the spinal trigeminal complex.

Abstract
INTRODUCTION The physiopathogenetic mechanisms possibly involved in sudden unexplained epileptic death (SUDEP), were investigated in the hemispherectomized rat. METHODS For this purpose, paroxysmal activity, vagal nerve firing, systemic blood pressure (BP), pulmonary artery pressure, and ECG were simultaneously recorded in an experimental animal model of epilepsy. Recordings were performed in basal conditions and during paroxysmal activity induced by topical application of penicillin-G at hypothalamic and mesencephalic level. During the experiment were also performed hemogas analysis and at end, samples of lung tissue were processed for histology. RESULTS Activation of hypothalamic (HEF) and mesencephalic (MEF) epileptic foci induced a significant increase of spontaneous vagal nerve firing that was strictly correlated to ECG impairments and hypotension. When paroxysmal activity extinguished, vagal nerve activity and cardiovascular parameters returned to basal conditions. However, in 25% of the animals, co-activation of HEF and MEF always triggered a vagal hypertone which was temporally correlated to cardiac arrhythmias, but also to hyperkalemia, acidosis, pulmonary hypertension and to animal death. Histological control in lungs of deceased animals showed an alveolar and perivessel oedema with an oedematous infiltration in the alveolar and bronchial spaces and mucous secretion. During ictal activity, comparison between survived and deceased animals showed significant differences in the incidence of ECG impairment of pulmonary artery pressures, pO2, and pCO2 pressures, and [K+], [HCO3-], and [pH], concentrations. DISCUSSION A possible explanation of the above observations is discussed in relationship to SUDEP physiopathogenesis.

Abstract
To verify the effectiveness and the incidence of complication in the transcutaneal celiac plexus block with CT-guided in the patient with intractable upper abdominal cancer, using alcoholic solutions to different concentrations (50% and 96%), previous insertion of the peridural catheter. From December 1997 to June 2002, studies were carried out on 24 patients with CT-guided percutaneous coeliac plexus neurolysis including 17 men and 7 women with inoperable abdominal malignancy and two with chronic pancreatitis. The patients were affected by very intense pain controllable only with high doses of analgesic narcotics. Before the procedure a catheter was installed in the peridurale space between L1-T12. To avoid general anesthesia, 40 mL of marcaine 0.5% was injected to relieve the back pain sometimes reported after the neurolysis, caused by the diffusion of alcohol in the coeliac plexus. This technique requires a posterior percutaneous procedural transaortic approach CT scan guided, to determine the correct position of the needle tips and the spread of neurolytic solution (40 mL of 96% + 3 mL of contrast medium) around the origin of the coeliac trunk's anatomical center of the plexus. The first 10 patients have received 40 mL of 50% ethyl alcohol + 3 mL of contrast medium. To evaluate the rate of the analgesia relief, a visual analogue pain score (VAS) was used before and 48 hours after the neurolysis. The percutaneous neurolysis of the celiac plexus is useful to relieve the pain in patients affected by cancer developing in upper abdomen. The CT-scan guide of the needle allows an omogeneous distribution of the contrast medium. The insertion of the peridural catheter made a complete analgesia and reduced the incidence of complications. Our method provided an excellent control of the pain in all patients. In our experience the pain relief was almost complete in patients treated with 96% ethyl alcohol solution (VAS from 8 before the treatment to 1, 48 hours after the treatment). The alcohol administered in elevated concentrations (96%), does not increase the incidence of complications.

Abstract
BACKGROUND Incident pain does not respond to opioid treatment and it is not easily relieved with other therapeutic strategies (local intrapleural or spinal analgesia, phenol blocks etc.). For this reason cervical percutaneous cordotomy at C(1)-C(2) interspace is the only effective antalgic therapy in patients whose life expectancy is more than three to six months. METHODS This study is a rectrospective review of 22 patients with cancer and incident pain from brachial, lumbar-sacral plexus injury and gluteal ulcer. RESULTS Cordotomy provided excellent contralateral side pain relief in 21 patients; pain relief was maintained up to death and to the moment of last observation in living patients. In one deaf patient it was impossible to carry out the procedure due to incomplete co-operation and pain returned after 48 hours. Ventilatory depression caused death in one patient. Other complications recorded included ataxia, headache, motor deficit, dysesthesia and orthostatic hypotension. CONCLUSIONS The conclusion is drawn that percutaneous cordotomy should, in carefully selected cases, be considered the only technique to relieve incident pain.

Abstract
Acute myocardial infarction in pregnancy is a rare condition with substantial risk of maternal and fetal death. There is very little information about the use in this setting of percutaneous coronary interventional therapy. Together with literature review on this topic, we present the case of a 33-year-old 39-week pregnant woman who sustained during labor an acute transmural anterior myocardial infarction. Immediately after successful cesarean section, she was treated by primary percutaneous coronary angioplasty and direct stenting of the left anterior descending coronary artery with maternal and fetal excellent outcome.

Abstract
In the present study the possible derangement of the autonomic system and its influence in life threatening arrhythmias were analysed during paroxysmal activity. In hemispherectomized rats a paroxysmal activation of the hypothalamic and mesencephalic cardioarrhythmogenic triggers was performed by topical application of penicillin-G. Blood gas parameters and electrical activity of the thalamus, hypothalamus, vagal nerve fibre, ECG and arterial blood pressure were simultaneously monitored in basal conditions and repeated after the appearance of paroxysmal activity. Temporal correlation analysis was carried out. Results showed that during activation of these triggers, the spontaneous vagal nerve fibre activity significantly increased and triggered the appearance of cardiac arrhythmias which could become life threatening and induce animal death when blood gas and electrolytic parameters were simultaneously impaired. These experiments suggest that fatal evolution of the heart impairment is related not only to an autonomic cardiac trigger, but also to a concomitant metabolic derangement, which most likely shares the same autonomic origin.

Abstract
The aim of this pilot study was to evaluate the safety and efficacy of the BiodivYsio phosphorylcholine-coated stent in the primary treatment of acute myocardial infarction. The BiodivYsio stent (Biocompatible) is a balloon-expandable stent, laser etched from a 316 L stainless steel tube. This device is coated with phosphorylcholine, a synthetic, hemocompatible phospholipid polymer that has been shown in experimental studies to reduce platelet and protein adhesion to the surface of the metal. One hundred consecutive patients within 24 hr of symptoms of onset of acute MI, treated with primary PTCA, were enrolled. After PTCA, stenting was attempted in all eligible lesions (reference diameter > or = 2.5 mm; no bend lesion > 45 degrees ). Poststenting regimens contained ticlopidine (500 mg/day) and aspirin (325 mg/day) and 6-12 hr of heparin infusion. Procedural success (TIMI > or = II and residual stenosis < 30%) was obtained in 70/74 cases (95%). TIMI grade III was restored in 90% of cases. In the patient group with procedural success (70 cases), 70 BiodivYsio stents were placed. After stenting, diameter stenosis decreased from 96% +/- 11% to 22% +/- 12% (P < 0.01) and minimal luminal diameter increased from 0.13 +/- 0.29 to 2.47 +/- 0.43 (P < 0.01). Nominal stent diameter was between 3.0 and 4.0 mm (mean, 3.5 +/- 0.4 mm). Stent length was between 11 and 28 mm (mean, 17 +/- 4.5 mm). Clinical follow-up was obtained in all patients; angiographic follow-up was performed in 65/70 (93%). No acute or subacute thrombosis was reported. Two in-hospital major adverse cardiac events (MACE) were reported due to a nontreated left main disease that required coronary artery bypass graft (CABG) surgery. At follow-up, MACE were found in 9 of 68 patients (13%), target lesion revascularization (TLR) in 6%, and CABG in the remaining 6%. Primary stenting with phosphorylcholine-coated stent leads to excellent short- and mid-term clinical outcomes and is associated with a restenosis rate of 12%.

Abstract
BACKGROUND Percutaneous transluminal myocardial revascularization (PTMR) is a new procedure to improve perfusion of the ventricular wall for patients with intractable angina and untreatable by surgery or conventional catheter-based intervention. Actually PTMR requires femoral approach to utilize 8F-9F system device. We now report the feasibility study of PTMR using a laser delivered through a novel Eclipse system and new 6F and 7F guiding catheters that allow to perform PTMR even in patients with peripheral vascular disease and particularly suitable for alternative small vascular access. METHODS Percutaneous vascular access for PTMR treatment was obtained via the femoral or radial artery. A 6F or 7F mono-directional catheter carrying flexible fiber optics was used with a Holmium laser (Eclipse system) and was placed across the aortic valve into the left ventricular cavity to create channels of 5 mm in depth from the endocardial surface into the myocardial tissue. From June 1999 to September 2000, 39 patients (28 males, 11 females, mean age 72 +/- 8 years, range 58-86 years) underwent PTMR with the Eclipse system. Preoperative mean Canadian Cardiovascular Society (CCS) angina class was 3.5 +/- 0.5 and previous myocardial procedures had been performed in 39 patients (18 coronary artery bypass graft and 31 coronary angioplasty). RESULTS The procedure was well tolerated and a procedural success was obtained in all patients (100%). We performed a mean of 19 +/- 7 channels in a mean fluoroscopy time of 21 +/- 9 min. We report only one procedural complication: one embolic stroke (2.4%). No hospital major adverse cardiac events were observed. The average length of hospital stay was 3.1 days. The mean CCS angina class at entry was 3.5 and it declined from 3.5 +/- 0.5 to 1.25 +/- 0.8 at discharge. At the follow-up of 8.2 +/- 3.9 months the mean CCS was 1.5 +/- 0.7. CONCLUSIONS This experience confirmed the safety and technical feasibility of PTMR with this mini-invasive approach with a reduction in operative and fluoroscopy time. The PTMR with the 6F or 7F guiding catheter is feasible in high risk patients even when the femoral approach is contraindicated. Immediate and short-term results confirm that a clinical improvement is obtained in most patients.

Abstract
The disposition of propofol in the blood and brain of New Zealand rabbits was studied in three groups of six rabbits. One group received a single anaesthetic dose; a second group received a 1-h infusion; and a third group was studied after the rabbits were judged to have recovered from a 1-h infusion. There was a high concentration of propofol in the red blood cell fraction and in the brain, however, the red blood cell concentration largely exceeded the one found in the brain in all groups of animals. This is consistent with the high fat solubility of diisopropylphenol. The possible effects of propofol sequestered in red blood cells is discussed.

Abstract
The sensitivity and electrophysiological patterns of paroxysmal activity induced in different brain structures by topical application of penicillin-G were evaluated in the rat. Recordings were carried out in five groups of animals, in telencephalon, diencephalon, mesencephalon, rombencephalon and spinal cords. The following analysis were carried out: frequency distribution histograms, latency and time course duration of paroxysmal activity, duration and amplitude of epileptic bursts. The results obtained showed that the nervous structures tested with penicillin-G had a different epileptogenic sensitivity and response pattern which significantly changed along the cerebral cortex-spinal cord axis. The highest epileptic sensitivity was observed in somatosensory cortex (SI) at 500-600 microns depth; in the other cortical layers, a significant lenghtening in latency was observed. Among the other structures, the spinal cord seemed to be the most sensitive target to the epileptogenic action of penicillin-G, whereas in the remaining structures, sensitivity significantly decreased in rostro-caudal direction. As far as the features of the paroxysmal activity are concerned, significant differences among tested structures were observed. In particular, within the SI cortex, the main differences were represented by the gradual increase in burst frequency and voltage from the surface to the IVth layer and by their subsequent decrease in deeper layers (V-VI). In the diencephalon, the paroxysmal activity was similar to that observed in more superficial and deeper cortical layers even though epileptic bursts showed a lower amplitude. Mesencephalon and rombencephalon displayed a paroxysmal activity with a distinctive feature, characterized by long lasting bursts of low amplitude, although bulbar outbursts showed a shorter duration than the mesencephalic ones. In the spinal cord, the epileptiform activity displayed a different paroxysmal pattern, characterized by the longest duration and the highest amplitude. The different sensitivities of the investigated brain structures to penicillin-G and the characteristics of the induced paroxysmal activity have been extensively discussed.

Abstract
The cardiovascular effects of simultaneous activation of hypothalamic and mesencephalic cardioarrhythmogenic triggers were studied in hemispherectomized rats. Paroxysmal activity of hypothalamic neurons (HEF), elicited by topical application of penicillin G on the thalamus, triggered short-lasting bradyarrhythmic episodes, up to a maximum of 6 s, and alterations in repolarization. In the hypothalamic neurons, an additional penicillin G epileptic focus at mesencephalic level (MEF) induced the enhancement of paroxysmal activity by a recruitment of new units and potentiation of their background activity. HEF+MEF triggered second-degree 2:1-8:1 atrioventricular (A-V) blocks, impairment of the A-V conduction, alterations in the recovery phase and bundle branch blocks. After HEF, the arterial blood pressure decreased by 4-6%. HEF+MEF induced a further reduction of 17% in systolic pressure only. It is possible that the enhancement of the HEF following MEF could depend on MEF spreading upward. The HEF, in turn, by spreading downward could influence the MEF and so activate, between HEF and MEF, a circuitry with reciprocal co-excitation that could explain the more serious cardiovascular alterations observed during HEF+MEF compared with those observed during HEF only or during MEF only. However, this cardiovascular impairment, which must be neurogenic in origin as it was observed in animals with normal acid-base and blood parameter values, did not induce heart death. Thus, additional concomitances must be considered, such as metabolic derangement which can occur during seizures, to explain sudden death in epileptic patients. Some aspects of metabolic complications in cardiac activity during epilepsy are also discussed.
