Pain Study in X-Linked Adrenoleukodystrophy in Males and Females.

Introduction: X-linked adrenoleukodystrophy (ALD) is a metabolic disorder in which very long chain fatty acids (VLCFAs) are accumulated in the nervous system and adrenal cortex, impairing their functions. Three main variants are described in males: adrenomyeloneuropathy (AMN), a cerebral form (cALD or cAMN) and Addison's disease only (AD), while for females no classification is used. To evaluate pain and the functional state of afferent fibers, a series of tests was carried out in male and female patients.

Cardiocirculatory intraoperative assessment during single-shot caudal anaesthesia in children: comparison between levobupivacaine and ropivacaine.

Background: Caudal block with levobupivacaine or ropivacaine is the most commonly used regional anaesthesia in children.

Methods: The aim of study was to compare the cardiocirculatory profile induced in two matched groups of young patients, submitted to caudal anaesthesia with levobupivacaine or ropivacaine for an elective subumbilical surgery. Sixty children were enrolled: thirty received levopubivacaine 0.

Menopause affects pain depending on pain type and characteristics.

Objective: Women are more affected than men by many chronic pain conditions, suggesting the effect of sex-related mechanisms in their occurrence. The role of gonadal hormones has been studied but with contrasting results depending on the pain syndrome, reproductive status, and hormone considered. The aim of the present study was to evaluate the pain changes related to the menopausal transition period.

Lymphocyte TRPV 1-4 gene expression and MIF blood levels in a young girl clinically diagnosed with HSAN IV.

Objective: Patients with congenital insensitivity to pain are unable to sense pain and temperature. They undergo many injuries, inflammatory state, and infections. Various mutations in the neurotrophic tyrosine kinase receptor gene have been implicated in this disorder.

Hormone replacement therapy in morphine-induced hypogonadic male chronic pain patients.

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.

Julia's placebo effect.

Placebo analgesia is the occurrence of an analgesic drug effect without drugs. The response is learned through conditioning and mediated by expectancy. It lies on the up-regulation of the pain-modulating areas and the down-regulation of the pain-encoding regions.

Endocrine consequences of opioid therapy.

Gonadal hormones are known to be affected by morphine and other opioids. In this paper, we summarize data collected in recent years which clearly indicate that the opioid-induced effects on steroid hormones depend on the opioid used and in some cases on the sex of the subject. Indeed morphine is able to reduce hormones like testosterone and cortisol in both male and female subjects in just a few hours, probably acting directly on peripheral glands.

Quantitative Real-Time PCR detection of TRPV1-4 gene expression in human leukocytes from healthy and hyposensitive subjects.

Background: Besides functioning as chemosensors for a broad range of endogenous and synthetic ligands, transient receptor potential vanilloid (TRPV) 1-4 channels have also been related to capsaicin (TRPV1), pain, and thermal stimuli perception, and itching sensation (TRPV1-4). While the expression of the TRPV1-4 genes has been adequately proved in skin, sensory fibres and keratinocytes, less is known about TRPV3 and TRPV4 expression in human blood cells.

Results: To study the gene expression of TRPV1-4 genes in human leukocytes, a quantitative Real-Time PCR (qRT-PCR) method, based on the calculation of their relative expression, has been developed and validated.

Increase of plasmatic beta-endorphin immunoreactive material in children in the perioperative period: the influence of the site of surgery.

Background: The primary aim of the study was to confirm the increase of plasmatic IR beta-endorphin material during the perioperative period in children. The second was to search for the factors responsible for this increment.

Methods: Seventy-two consecutive children undergoing a surgical procedure were recruited.

Sensory phenotype assessment in a young girl affected by congenital insensitivity to pain (CIPA).

Sensory phenotype was assessed in a young girl affected by congenital insensitivity to pain (CIPA) scheduled for an open surgical drainage. The sensory profile showed that only the Abeta fibers were functioning normally, whereas Adelta and C fibers did not respond to nociceptive stimuli. On the basis of these findings and the results of cardiovascular reflexes, she was submitted to abscess incision and debridement under midazolam sedation alone.

Protocols to manage postoperative pain in neonates and children hospitalized in a surgical ward. Methodological issues and cultural background.

The authors describe the cultural background and methods they adopted to construct protocols for analgesia in newborns and children hospitalized in a surgical ward. Drugs and dosages are reported in the Appendix, whereas scales for pain measurement and cut off ratings for rescue doses (or otherwise relevant) are described respectively in Tables 2 and 3. Genetics and cognitive structures play a crucial role in pain and analgesia.

Cross-sex hormone administration changes pain in transsexual women and men.

Chronic pain is gender-related, since there is a clear predominance of one sex with respect to the other in most pain syndromes. Gonadal hormones are known to affect the occurrence and incidence of pain. Transsexuals receive cross-sex hormones to develop and maintain somatic characteristics of the opposite sex: male to female transsexuals (MtF) are administered estrogens and anti-androgens, while female to male transsexuals (FtM) are administered androgens.

Severe withdrawal syndrome in three newborns subjected to continuous opioid infusion and seizure activity dependent on brain hypoxia--ischemia. A possible link.

Background: The aim of this investigation was to verify whether brain hypoxia represented a risk factor for the occurrence and severity of opioid abstinence syndrome.

Methods: Three newborns who manifested seizure activity as a result of hypoxia, focal brain ischemia, and hypoxia and sepsis, respectively, were compared with 17 neonates who suffered from hypoxia without developing seizure activity.

Results: The first three neonates suffered a severe withdrawal syndrome (a rating on the neonatal abstinence score>17), the others did not.

A pain educational program for pediatric nurses: topics and key points.

The undertreatment of pain in children may lead to severe consequences. Basic knowledge about pain in this category of patients may improve pain assessment and its management. In line with the Project established by the Italian Ministry of Health, authors planned an educational program devoted to the pediatric nurses.

Removal of an unexpected tracheal foreign body after five months.

Foreign body aspiration can produce serious pulmonary diseases. Timely diagnosis and appropriate treatment is important to prevent long-term complications in affected children. We report the case of a 15-month-old child with a 5-month history of regurgitation, vomiting, recurrent tracheobronchitis, and pneumonia.

Exposure of personnel to sevoflurane during paediatric anaesthesia: influence of professional role and anaesthetic procedure.

Background And Objective: This study was performed to determine the individual exposure of paediatric operating theatre personnel to sevoflurane and to evaluate the impact of inhalation induction and various airway approaches on exposure to airborne sevoflurane.

Methods: Mean individual environmental (workplace air) exposure to sevoflurane and a biomarker of exposure (urinary sevoflurane) were monitored in 36 subjects (10 anaesthetists, 10 surgeons, 12 nurses and 4 auxiliary personnel) working in two paediatric operating rooms.

Results: Environmental and urinary values were significantly greater in anaesthetists compared with other groups, with median values of 0.

[In-hospital pediatric cardiopulmonary resuscitation].

Between 0,7-3% of pediatric patients may require resuscitation during hospital stay. The physicians of the Pediatric Intensive Care Unit of the C.O.

Peripherally inserted central venous catheters in preterm newborns: two unusual complications.

This report describes the case of two newborns who suffered unusual complications after peripheral insertion of a central venous catheter. In one baby a fragment of the catheter tip became embolized in a peripheral branch of the left pulmonary artery. In the other baby, the catheter perforated a peripheral branch of the pulmonary artery, giving rise to chemical pneumonitis with extensive pleural effusion.

The pain locus of control orientation in a healthy sample of the Italian population: sociodemographic modulating factors.

We studied the pain locus of control orientation of the Italian population and the possible influence of the ethnocultural background and sociodemographic characteristics on this attributional style. An Italian version of the Pain Locus of Control (PLOC-It) scale was administered to 144 healthy subjects, divided into two ethnocultural areas (North vs South) and stratified by age (per decade 21-60), gender (female and male) and educational level (3). The Powerful Other subscale had the highest mean score, followed by the Internality and Chance subscales.

[Inhalation of foreign bodies].

Accidental aspiration of a foreign body (FB) is an event which is reasonably frequent and dramatic in children and is still today one of the main causes of death due to accidents at home in children up to three-four years of age. The severity of the clinical picture varies according to the size, shape, type and site of arrest of the material aspirated and can be associated with both severe asphyxial forms and forms with insidious and vague symptoms which are difficult to diagnose correctly. A late diagnosis is however a fairly common event in literature.

Individual pain history and familial pain tolerance models: relationships to post-surgical pain.

Objectives: (a) To investigate the influence of previous pain experience and familial pain tolerance models on postsurgical pain; (b) to investigate the effect of personality traits on vicarious learning.

Design: Before surgery, the patients completed the Minnesota Multiphasic Personality Inventory (MMPI), Eysenck Personality Inventory (EPI), and State-Trait Anxiety Inventory (STAI) personality tests. They also underwent a semi-structured interview to collect information on familial pain tolerance models and their own pain history.

Self-control expectancy and postsurgical pain: relationships to previous pain, behavior in past pain, familial pain tolerance models, and personality.

The importance of self-control expectancy on postsurgical pain was studied in 126 patients enrolled in a particular clinical setting. The contribution of previous pain experiences, past behaviors, vicarious experiences, and personality traits to self-control expectancy reported by patients was also investigated. To collect this information, a specific questionnaire and a semistructured interview were given before surgery.
