Care strategies and therapeutic pathways for chronic pain patients in Abruzzo Region, Italy.

BACKGROUND: Chronic pain is considered to be among the most disabling and costly diseases in North America, Europe and Australia. A large survey was conducted on chronic pain in Europe, called Pain in Europe. Italy ranks third in Europe in terms of prevalence, with 26% of the population suffering from chronic pain at some point. In 2010 Italy passed Law 38/2010, to ensure treatment for pain control in patients with oncological diseases as well as in patients with chronic non-cancer pain through a network of care services. This study aims to provide preliminary information regarding the application of L.38/2010 in the Abruzzo region of Italy. METHODS: A descriptive study was conducted on a non-probabilistic sample of people who attended pain therapy centres of the local health service in 2014. The patients (129) were interviewed by centre staff using a validated questionnaire. Recruitment was carried out by enrolling consecutive cases over a three-month period (February to April). RESULTS: Almost two-thirds of the patients had visited several physicians before requesting help. The initial visit to the pain therapy centre was made after some months in 37.2% of cases, and in 38% of patients it was made years after the onset of pain. The reasons given for this long wait before seeking specialist medical treatment for chronic pain reveal a wait-and-see attitude on the part of patients, who controlled their pain by taking painkillers. Responsibility for this delay in requesting assistance can however also be attributed 'externally' to the fact that patients were not aware that this kind of centre was available. CONCLUSION: The results of the study describe, in a regional context, a situation in which L.38/2010 is hard to apply. The study showed how the care pathway for these patients is still characterised by difficulty in accessing the network of local services. Clearly, more effort needs to be directed towards an effective application of L.38/2010, with increased availability of resources to develop and strengthen the network of services at regional level.

Opioids in the Elderly Patients with Cognitive Impairment: A Narrative Review.

INTRODUCTION: Assessment and management of pain in elderly people with cognitive impairment is particularly challenging. Physiological changes due to aging as well as comorbidities and polypharmacy are responsible for a complex clinical approach. Concomitantly, in cognitive impairment, including advanced dementia, changes in the central nervous system along with changes in the peripheral nervous system due to aging have a significant impact on pain perception. Sometimes clinicians decide to prescribe opioids to relieve pain, also without a clear indication. This review aims to investigate the effect of opioids in elderly patients with cognitive impairment. METHODS: A literature search of PubMed/Medline, Scopus, and Cochrane databases was conducted using keyword searches to generate lists of articles that were screened for relevance by title and abstract to give a final list of articles for full-text review. Further articles were identified by scanning the reference lists of the full-text articles. DISCUSSION: This review discusses the complex physiological and pharmacological changes in the elderly as well as the neurological changes that affect pain perception in this population. Additionally, it focuses on cognitive impairment and pain in Alzheimer's disease and other dementias, the pain assessment in the elderly with cognitive impairment as well as the safety of opioid use in the elderly. Information regarding opioid prescription in nursing homes and recorded indications for opioid use, type and dosing of opioids, and compliance of treatment in advanced dementia are also provided. CONCLUSIONS: Opioid prescription in the elderly population with cognitive impairment is particularly complex. All healthcare professionals involved in the care of such patients need to be aware of the challenges and strive to ensure analgesic use is guided by appropriate and accurate pain assessment.

Influence of sex and gender on the management of late-stage knee osteoarthritis.

PURPOSE: The exact nature of sex and gender differences in knee osteoarthritis (OA) among patient candidates for total knee arthroplasty (TKA) remains unclear and requires better elucidation to guide clinical practice. The purpose of this investigation was to survey physician practices and perceptions about the influence of sex and gender on knee OA presentation, care, and outcomes after TKA. METHODS: The survey questions were elaborated by a multidisciplinary scientific board composed of 1 pain specialist, 4 orthopedic specialists, 2 physiatrists, and 1 expert in gender medicine. The survey included 5 demographic questions and 20 topic questions. Eligible physician respondents were those who treat patients during all phases of care (pain specialists, orthopedic specialists, and physiatrists). All survey responses were anonymized and handled via remote dispersed geographic participation. RESULTS: Fifty-six physicians (71% male) accepted the invitation to complete the survey. In general, healthcare professionals expressed that women presented worse symptomology, higher pain intensity, and lower pain tolerance and necessitated a different pharmacological approach compared to men. Pain and orthopedic specialists were more likely to indicate sex and gender differences in knee OA than physiatrists. Physicians expressed that the absence of sex and gender-specific instruments and indications is an important limitation on available studies. CONCLUSIONS: Healthcare professionals perceive multiple sex and gender-related differences in patients with knee OA, especially in the pre- and perioperative phases of TKA. Sex and gender bias sensitivity training for physicians can potentially improve the objectivity of care for knee OA among TKA candidates.

European Pain Federation position paper on appropriate opioid use in chronic pain management.

Poorly controlled pain is a global public health issue. The personal, familial and societal costs are immeasurable. Only a minority of European patients have access to a comprehensive specialist pain clinic. More commonly the responsibility for chronic pain management and initiating opioid therapy rests with the primary care physician and other non-specialist opioid prescribers. There is much confusing and conflicting information available to non-specialist prescribers regarding opioid therapy and a great deal of unjustified fear is generated. Opioid therapy should only be initiated by competent clinicians as part of a multi-faceted treatment programme in circumstances where more simple measures have failed. Throughout, all patients must be kept under close clinical surveillance. As with any other medical therapy, if the treatment fails to yield the desired results and/or the patient is additionally burdened by an unacceptable level of adverse effects, the overall management strategy must be reviewed and revised. No responsible clinician will wish to pursue a failed treatment strategy or persist with an ineffective and burdensome treatment. In a considered attempt to empower and inform non-specialist opioid prescribers, EFIC convened a European group of experts, drawn from a diverse range of basic science and relevant clinical disciplines, to prepare a position paper on appropriate opioid use in chronic pain. The expert panel reviewed the available literature and harnessed the experience of many years of clinical practice to produce these series of recommendations. Its success will be judged on the extent to which it contributes to an improved pain management experience for chronic pain patients across Europe. SIGNIFICANCE: This position paper provides expert recommendations for primary care physicians and other non- specialist healthcare professionals in Europe, particularly those who do not have ready access to specialists in pain medicine, on the safe and appropriate use of opioid medications as part of a multi-faceted approach to pain management, in properly selected and supervised patients.

Hemodynamic variations during thoracic and abdominal stop-flow regional chemotherapy.

AIMS: The aim of this study was to study hemodynamic modifications during thoracic and abdominal stop-flow regional chemotherapy and to evaluate the need for routine hemodynamic monitoring during such kind of procedures. METHODS: Thirty patients, aged 17-67 years, ASA physical status II-III, scheduled for thoracic (group A, n = 15), and abdominal (group B, n = 15) stop-flow regional chemotherapy were enrolled. Heart rate (HR), electrocardiogram lead I and V(5), end tidal carbon dioxide (ETCO(2)), arterial oxygen saturation (SaO(2)), systolic, diastolic and mean arterial pressure (SBP, DBP, MAP), mean pulmonary arterial pressure (MPAP), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), cardiac output (CO), stroke volume (SV), stroke index (SI), systemic vascular resistance (SVR), pulmonary vascular resistance (PVR), left cardiac work (LCW), right cardiac work (RCW), left cardiac work index (LCWI), right cardiac work index (RCWI), cardiac index (CI), and body O(2) consumption (VO(2)) were recorded. RESULTS: After aortic and inferior vena cava endovascular occlusion (T(1)), a significant reduction of CO and SV, associated with an increase of CVP, MAP, PAPM and PCWP were observed. A concomitant reduction of CI and increase of SVR and PVR were registered. The VO(2) was significantly reduced compared to basal values in both groups. After deflating aortic and vena cava balloons (T(2)), CO, SV and CI increased with respect to basal value p < 0.05) whereas MAP, CVP, PAPM, PCWP and calculated parameters (SVR, PVR) showed a significant reduction compared to T(1). The oxygen consumption was significantly higher than that of basal values p < 0.05. After hemofiltration (T(3)), all hemodynamic variables were comparable with the basal values. Modifications of direct and calculated parameters, during the stop-flow period, showed a similar trend in both study groups, without any statistically significant difference. No ST modifications at ECG were noted during all perioperative period. CONCLUSIONS: The results of this study have confirmed in both groups, the safety of stop-flow regional chemotherapy procedure, despite endovascular occlusion of the aorta and inferior cava vein. The hemodynamic and oxygenation changes are reversible and did not produce any ST modifications at ECG during all perioperative period. Routine pulmonary artery catheterization is thus unnecessary, except in high cardiac risk patients.

Epidural morphine pretreatment for postepisiotomy pain.

OBJECTIVE/DESIGN: A randomized double-blind controlled study was conducted on two groups of 45 parturients to evaluate the importance of the timing of epidural morphine administration for the relief of postepisiotomy pain. Both groups had preemptive analgesia by continuous lumbar epidural bupivacaine blockade. Upon completion of the episiotomy repair and before the onset of pain, the patients received epidural injections of 3 ml saline with or without 2 mg morphine in groups A and B respectively. When pain appeared, group A patients received an epidural injection of 3 ml saline while group B patients received 2 mg morphine in 3 ml saline. Postepisiotomy pain level was evaluated by a visual analogue scale. RESULTS: The incidence of pain in group B women following epidural morphine administration was 68.6%. This was significantly higher than that of group A at 15.6% (p < 0.01). Furthermore, group B showed that the rate of effective pain relief after 2 mg epidural morphine significantly decreases as the level of pain intensity rises (p < 0.01). CONCLUSION: Epidural morphine for postepisiotomy pain is much more effective if administered before the onset of pain.

Nutrition support after total laryngectomy.

This study was performed to evaluate the influence of different nutrition supports (enteral vs parenteral) on nutritional status, postoperative complications, and length of hospitalization in patients undergoing total laryngectomy. Forty-eight patients were divided at random into two groups and received enteral nutrition support by percutaneous endoscopic gastrostomy with a casein and soy-based polymeric formula blended with a modular protein (group A) or a balanced formula in total parenteral nutrition given through a subclavian venous catheter (group B). The results show a satisfactory preservation of nutritional status after total laryngectomy and no significant differences in the nutritional parameters between groups fed enterally or parenterally; however, percutaneous endoscopic gastrostomy could avoid many problems related to enteral nutrition support for patients undergoing laryngectomy. This route of administration was well tolerated by all the patients and, moreover, the percutaneous endoscopic gastrostomy-related complications were clinically less significant than those associated with total parenteral nutrition; this fact could explain the longer hospitalization for group B (34 +/- 11 vs 26 +/- 11 days) (p < .05).

[Continuous peridural analgesia-anesthesia during labor. Experiences and considerations]. / Analgo-anestesia peridurale continua in travaglio di parto. Nostre esperienze e considerazioni.

Fifty pregnant women attending the Obstetrics Department of the University of Aquila were included in the study. Patients were matched for age, weight, height, parity, Bishop index, temperature, arterial pressure, and cardiotopography. Twenty-five patients were assigned to the control group, the remaining twenty-five received peridural analgo-anesthesia during labour and birth so as to create a continuous lumbar epidural block. The results confirmed that this method of anesthesia is an aid against psycho-physical stress and pain in pregnant women.

Propofol and thiopentone for caesarean section revisited: maternal effects and neonatal outcome.

In 56 women undergoing elective caesarean section, general anaesthesia was induced with either propofol 1% or thiopentone 2.5% followed by 50% nitrous oxide in oxygen and isoflurane 0.75% until delivery. In the thiopentone group the arterial pressure rose following tracheal intubation and skin incision, while in the propofol group there was a significant tendency to hypotension immediately following induction of anaesthesia. There were differences in electroencephalogram (EEG) between the groups, while laryngoscopy, intubation and surgical stimulation had no effect on EEG pattern. Recovery after anaesthesia did not differ between groups. None of the patients had recall of the intraoperative period, but 53% of patients induced with propofol showed signs of light anaesthesia between induction and delivery. Neonates in the propofol group had lower Apgar scores 1 min after birth than those in the thiopentone group, but these differences were no longer significant at 5 min. No differences were noted in neurobehavioural status at 1, 4 and 24 h.

Epidural mepivacaine for cesarean section: effects of a pH-adjusted solution.

STUDY OBJECTIVE: To determine the clinical effects of the alkalinization of 2% mepivacaine with epinephrine used for epidural block during cesarean section. DESIGN: Randomized, double-blind, placebo-controlled (standard commercial preparation of 2% mepivacaine with epinephrine) study. SETTING: Inpatient obstetric department at a general hospital. PATIENTS: Seventy patients scheduled for elective cesarean section under epidural anesthesia. INTERVENTIONS: Two groups of 35 patients each receiving either the standard commercial preparation of mepivacaine or the pH-adjusted solution (prepared with the addition of 0.1 meq/ml of sodium bicarbonate to the standard commercial solution). MEASUREMENTS AND MAIN RESULTS: Measurements of sensory (pinprick) and motor (Bromage's criteria) block were taken at 1- to 2-minute intervals beginning after the completion of the epidural injection. Increasing the pH of the mepivacaine resulted in a significant shortening of the time of analgesia onset (9.3 minutes compared with 16.01 minutes, p less than 0.01) and of peak effect (11.1 minutes compared with 21.2 minutes, p less than 0.01). The alkalinization did not affect duration of the block, intensity of motor block, or mean dose of local anesthetic used. CONCLUSION: The alkalinization allowed the surgery to proceed more rapidly, significantly decreasing the time interval between epidural block and delivery of the infant.

Which induction drug for cesarean section? A comparison of thiopental sodium, propofol, and midazolam.

STUDY OBJECTIVE: To determine maternal and neonatal effects of three different induction drugs (thiopental sodium, propofol, and midazolam) for cesarean section. DESIGN: Randomized, double-blind study. SETTING: Inpatient obstetric department at a general hospital. PATIENTS: 90 healthy patients undergoing elective cesarean section with general anesthesia. INTERVENTIONS: 3 groups of 30 patients each receiving thiopental 5 mg/kg, propofol 2.4 mg/kg, or midazolam 0.3 mg/kg for induction of anesthesia. MEASUREMENTS AND MAIN RESULTS: Time to induce anesthesia, hemodynamic changes, depth of anesthesia, recovery after anesthesia, placental transfer, and neonatal outcome (Apgar and neurobehavioral examinations) were studied. In the thiopental and midazolam groups, systolic blood pressure and heart rate rose following endotracheal intubation and skin incision (p < 0.001 and p < 0.0025, respectively), while in the propofol group, there was significant hypotension after induction (p < 0.005). Electroencephalographic patterns showed a light depth of anesthesia with propofol and midazolam between anesthesia induction and delivery, confirmed by the presence of clinical signs of light anesthesia in 50% of propofol patients and 43% of midazolam patients. Time to induce anesthesia was longer with midazolam (p < 0.0001). Neonates in the midazolam and propofol groups had lower Apgar and neurobehavioral scores than those in the thiopental group. Umbilical artery to umbilical vein ratios were above 1 in the propofol and midazolam groups. CONCLUSION: Thiopental still remains the first-choice induction drug for cesarean section. The slow induction time with midazolam may put the mother at risk for pulmonary inhalation. A plane of anesthesia that may risk awareness and potential neonatal depression is the main drawback of the two newer induction drugs.

Bio-electrical brain relations of pain and acupuncture effects on EEG spectral analysis in healthy volunteers.

Pain description and objective evaluation is difficult. In the last few years, a number of neuro-physiological methods have been used in the study of pain and acupuncture analgesia. EEG spectral analysis allows the description and objective quantification of brain bio-electrical activity changes. The present study aims at evaluating ischemic experimental pain, electroacupuncture (EA) and ischemic pain following EA on EEG spectral analysis in healthy volunteers.

The international CHANGE PAIN physician survey: does specialism influence the perception of pain and its treatment?

OBJECTIVES: This survey explores how physicians perceive chronic non-cancer pain, and examines their opinions on current treatment options. METHODOLOGY: The computer-based survey comprises a questionnaire that is completed by physicians, mostly at professional conferences and congresses, but also online. The focus is on pain specialists, primary care physicians and other specialists (such as neurologists and rheumatologists), to discover any differences in their approach to treating chronic non-cancer pain. RESULTS: No common understanding existed of where severe pain starts on an 11-point Numeric Rating Scale. Overall, two-thirds of respondents aim for treatment to reduce pain intensity to an NRS score of 2-4, with primary care physicians tending to aim for lower scores. All three groups considered reduction of pain to be the most important treatment goal, followed by quality of life. Asked to rank the most important factors when choosing an analgesic agent to treat severe, chronic non-cancer pain, respondents ranked efficacy first, tolerability second, and quality of life third. In each rank, more primary care physicians chose these options than in the specialist groups. More pain specialists used classical strong opioids often or very often - and for longer - than did physicians in the other two groups. Nausea/vomiting, bowel dysfunction and somnolence were ranked the first, second and third main reasons, respectively, for treatment failure with these agents. Over 90% of respondents used combination treatment rather than monotherapy to treat severe, chronic pain, but no fewer than 176 different combinations were cited. CONCLUSIONS: Pain reduction and improvement in quality of life are the most important treatment goals. Wide variation in treatment indicates that no single drug is particularly good for managing chronic pain, and suggests that current treatment is not evidence-based. Differences between the groups imply that first-line treatment is more cautious and conventional. The key limitations of this survey include its small sample size, informal implementation and lack of detail regarding the respondents surveyed.

ITalian Observational Study of the management of mild-to-moderate Post-Operative Pain (ITOSPOP).

BACKGROUND: The multicenter observational ITalian Observational Study on the management of mild-to-moderate PostOperative Pain (ITOSPOP) was carried out in 24 hospitals to describe current postoperative pain management in Italy and the intensity of pain experienced by patients during the first 48 hours after surgery. METHODS: Adult patients, after surgery expected to result in mild-moderate postoperative pain, underwent six evaluations. The primary endpoint was the level of organization and standardization of postoperative pain management. Secondary objectives included the intensity of postoperative pain, and an assessment of incident pain, postoperative analgesic and concomitant treatment administration. RESULTS: Only 16.7% hospitals had an acute pain service and 41.7% hospitals applied a standardized protocol for postoperative pain management. The majority (>60%) of the 1952 patients monitored underwent all six assessments, >70% of which were performed by a physician. The proportion of patients with moderate pain decreased during the study period, but almost 10% of patients still experienced moderate pain at study end. Mild pain was reported by 50% of the patients for the entire study duration. At the final assessment, 5% of patients still presented with incident pain frequently interfering with daily activities. Most patients were treated with analgesics, but 20% of patients did not receive any pain medications despite experiencing pain. CONCLUSION: The level of organization and standardization of postoperative pain management in Italian hospitals remains low. Postoperative analgesic treatment remained suboptimal and almost two-thirds of patients continued to experience pain.

Pharmacological treatment of chronic pain - the need for CHANGE.

BACKGROUND: Although chronic pain affects around 20% of adults in Europe and the USA, there is substantial evidence that it is inadequately treated. In June 2009, an international group of pain specialists met in Brussels to identify the reasons for this and to achieve consensus on strategies for improving pain management. SCOPE: Literature on chronic pain management was reviewed, and information presented to and discussed by a panel of experts. FINDINGS: It was agreed that guidelines are not universally accepted by those involved in pain management, and pain treatment seems to be driven mainly by tradition and personal experience. Other factors include poor communication between patients and physicians, the side effects of analgesic drugs, and limited individualisation of therapy. Difficulty in maintaining the balance between adequate pain relief and acceptable tolerability, particularly with strong opioids, can lead to the establishment of a 'vicious circle' that alternates between lack of efficacy and unpleasant side effects, prompting discontinuation of treatment. The medical community's understanding of the physiological differences between nociceptive pain and neuropathic pain, which is often more severe and difficult to treat, could be improved. Increasing physicians' knowledge of the pharmacological options available to manage these different pain mechanisms offers the promise of better treatment decisions and more widespread adoption of a multi-mechanistic approach; this could involve loosely combining two substances from different drug classes, or administering an analgesic with two different mechanisms of action. In some circumstances, a single compound capable of addressing both nociceptive and neuropathic pain is desirable. CONCLUSIONS: To improve patient outcomes, a thorough understanding of pain mechanisms, sensitisation and multi-mechanistic management is required. Universal, user-friendly educational tools are therefore required to familiarise physicians with these topics, and also to improve communication between physicians and their pain patients, so that realistic expectations of treatment can be established.

Anxiolysis and postoperative pain in patients undergoing spinal anesthesia for abdominal hysterectomy.

AIM: The relationship between pain and psychological factors is well known. The aim of the study was to evaluate the influence of lorazepam, given before total abdominal hysterectomy, on postoperative pain control. METHODS: Sixty patients, enrolled in the study, were defined as either anxious or not anxious when the State/Trait Anxiety Inventory (STAI) score was =/>51 or =/< 50, respectively. The anxious patients were randomly assigned to receive oral lorazepam 0.035 mg/kg the night and 2 h before surgery (Group A), or placebo at the same time (Group B). The not anxious patients were assigned to receive oral lorazepam 0.035 mg/kg the night and 2 h before surgery (Group C), or placebo at the same time (Group D). Anesthesia was performed with subarachnoidal block. Ketorolac was used for postoperative pain. As rescue drug, tramadol was administered using a patient controlled analgesia (PCA) modality. Postoperative pain was assessed during the 24 h after surgery by tramadol consumption. RESULTS: Tramadol consumption was significantly greater in Group B (216.3+/-58.9 mg) than in Groups A, C and D respectively (150.9+/-28.9 mg; 153.6+/-39.9 mg; 154.4+/-39.9 mg). Group B showed a significantly higher pain score compared to the other groups during the first 8 h. No difference in patient satisfaction with perioperative treatment was noted. CONCLUSION: Preoperative lorazepam reduced perioperative anxiety. This could explain the better postoperative pain control in patients undergoing hysterectomy, a very stressful surgical procedure.

Parenteral nutrition in ventilated patients with chronic obstructive pulmonary disease: long chain vs medium chain triglycerides.

AIM: The aim of this study was to assess the usefulness of a lipid formulation containing a physical mixture of medium (MCT) and long chain triglycerides (LCT) compared with a long chain triglycerides emulsion in patients affected by chronic obstructive pulmonary disease with acute respiratory failure. METHODS: Twenty-four patients requiring mechanical ventilation were randomly selected in 2 groups and received total parenteral nutrition. Twelve patients received a MCT/LCT emulsion (50:50), the others used a 100% LCT emulsion. Nutritional status, metabolic rate, time of ventilatory support and weaning were evaluated. RESULTS: Both groups showed an improvement of all nutritional parameters evaluated; oxygen uptake, carbon dioxide output and respiratory gas exchange ratio were similar in both groups. The duration of mechanical ventilation was not significantly different; however, the time of weaning in the MCT/LCT group was significantly shorter. The longer weaning time in the LCT group patients could be related to vasoactive intermediates deriving from long chain fatty acids. The T-cell subsets, which were evaluated for both groups, showed a significant decrease of T helper-T suppressor ratio in the LCT group. CONCLUSION: MCT/LCT emulsion is an effective lipid supplementation and should be considered the therapy of choice in COPD patients; however, the relationship between lipid emulsions administered and length of weaning requires further investigations.

Cervical pain and headache in patients with facial asymmetries: the effect of orthognathic surgical correction.

AIM: Facial asymmetries are often associated with cervicobrachial pain and headache. The aim of the study was to evaluate the influence of surgical orthognathic correction of facial asymmetries on the intensity of cervicobrachial pain and headache in the short and long term. METHODS: Thirty-two patients affected by maxillomandibular asymmetries associated with pain referred to occipital, cervical, dorsal and scapulohumeral areas who were undergoing orthodontic surgical correction were enrolled in the study. The pain intensity at rest and on fibromyalgia trigger points was assessed using a 0-10 Visual Analogue Scale (VAS) preoperatively (T(0)) and 5 days (T(1)), 6 months (T(2)) and 12 months (T(3)) after surgery. Functional limitation was evaluated by the same method at T(0),T(2) and T(3). RESULTS: VAS scores at rest were significantly lower at T(1), T(2) and T(3) compared to T0 in every area to which pain was referred. After 12 months (T(3)), pain at rest was completely absent in 23 patients (71.8%) in the occipital region, in 23 patients (71.8%) in the cervical area, in 22 patients (68.7%) in the dorsal area, and in 28 patients (87.5%) in the scapulohumeral area. In the other patients, the pain scores in all areas were < 1 (0.77, 0.83, 0.95, 0.5 in the occipital, cervical, dorsal, and scapulohumeral areas respectively). The VAS at neck fibromyalgia points were significantly reduced at T(1), T(2), T(3) and functional limitation was improved at T(3) and T(4) (P=0.00). CONCLUSION: This study appears to demonstrate the utility of orthognathic surgery when facial asymmetry is associated with cranial-cervicobrachial pain syndrome, presumably through a new musculoskeletal rearrangement of stomatognathic apparatus. Indeed, the surgical correction has resulted in morphological, functional and symptomatic effects.
