There is growing interest in the role that physical illness and pain might play in exacerbating problem behavior in individuals with developmental disabilities. Assessment of these factors, however, is often difficult since many individuals have minimal verbal communication skills. In response to this difficulty, we developed a sequential method of assessment involving retrospective and prospective measurement strategies. We found that the frequency and intensity of problem behavior was greater on "sick" days than on "well" days. Further, the higher the level of pain, the greater was the frequency and intensity of problem behavior. We discuss the concept of pain as a setting event for problem behavior and the intervention strategies that follow from this conceptualization.

Previous studies have found beneficial effects of aromatherapy massage for agitation in people with dementia, for pain relief and for poor sleep. Children with autism often have sleep difficulties, and it was thought that aromatherapy massage might enable more rapid sleep onset, less sleep disruption and longer sleep duration. Twelve children with autism and learning difficulties (2 girls and 10 boys aged between 12 years 2 months to 15 years 7 months) in a residential school participated in a within subjects repeated measures design: 3 nights when the children were given aromatherapy massage with lavender oil were compared with 14 nights when it was not given. The children were checked every 30 min throughout the night to determine the time taken for the children to settle to sleep, the number of awakenings and the sleep duration. One boy's data were not analyzed owing to lengthy absence. Repeated measures analysis revealed no differences in any of the sleep measures between the nights when the children were given aromatherapy massage and nights when the children were not given aromatherapy massage. The results suggest that the use of aromatherapy massage with lavender oil has no beneficial effect on the sleep patterns of children with autism attending a residential school. It is possible that there are greater effects in the home environment or with longer-term interventions.

The pathogenesis of idiopathic chronic pancreatitis remains poorly understood despite the high expectations for ascribing the pancreatic damage in affected patients to genetic defects. Neither mutations in the cationic trypsinogen gene nor mutations of the cystic fibrosis conductance regulator gene account for the chronic pancreatitis noted in most patients with idiopathic chronic pancreatitis. Attempts to find an autoimmune basis for the pancreatitis in these patients have not been very successful. The diagnosis of small duct idiopathic chronic pancreatitis remains a great source of frustration for clinicians. Such patients with negative results of radiographic studies often cannot be diagnosed unless a hormone stimulation test such as a secretin test is performed. Although the porcine biologic form of secretin, which has been used to diagnose chronic pancreatitis, became unavailable because of widespread use in the treatment of children with autism, a synthetic form of porcine secretin has now been approved by the US Food and Drug Administration and is available. The true value of endoscopic ultrasonography in diagnosing small duct chronic pancreatitis remains to be fully defined. Endoscopic ultrasonography is becoming the test of choice in detecting radiographic abnormalities in both the parenchyma and ducts of the pancreas. Endoscopic ultrasonography-guided celiac plexus block can be performed relatively easily and very safely. It can provide excellent short-term pain relief in some patients, but reliable predictors of which patients will be successful with this therapy are not yet available. Because long-term follow-up data on the use of endoscopic ultrasonography in this respect are not available, and because the pain of chronic pancreatitis is, indeed, chronic, the role of endoscopic ultrasonography-guided celiac plexus block should be limited to treating those patients with chronic pancreatitis whose pain has not responded to other modalities.

High incidences of Small Cell Carcinoma & Adenocarcinoma of the lung, Astrocytoma & Glioblastoma Multiforme of the brain and Mesothelioma of the lung were found in those who had a high accumulation of Asbestos in the eyes and upper respiratory system (nose, larynx, trachea, etc.). When measured non-invasively using the Bi-Digital O-Ring Test (BDORT), brain tumors had the highest concentration of Asbestos (0.2 approximately 2.1 mg BDORT units). Relatively high levels of Asbestos (0.2 approximately 0.6 mg BDORT units) were found in: Squamous Cell Carcinoma of the lungs & esophagus, Adenocarcinoma of the larynx & breast, myelogenic leukemia, arteries of these cancers, left ventricle of failing heart, myocardial infarction, some of the narrowed arteries, varicose veins, cataracts, balding heads, hot flashes, Alzheimer's Disease and Autism. A small, round or ellipsoidal area, with diameter of 5 mm or less, was found near the center of every cancer tissue with a higher level of Asbestos (1 approximately 3 mg), As, Zn, Cr and Se, than in the rest of the tumor; this small area may be where the cancer initiated. Among areas of intractable pain with frequent recurrence and gradual worsening, about 0.2 approximately 0.5 mg BDORT units (or higher) of Asbestos were found. The author found that in the Astrocytoma and many other cancer patients, the optimal dose of DHEA produced very significant reductions of cancer cell telomere from over 1400 ng in the brain tumors (and over 900 ng in other cancers) to close to or less than 1 yg (=10(-24) g), with circulatory improvement by reduction of TXB2. Unlike the standard, widely used treatment with DHEA 25 approximately 50 mg daily, which is an overdose; we only gave one optimal dose (1.5 approximately 12.5 mg) and the beneficial effects usually lasted anywhere between 3-6 months, unless inhibiting factors were introduced. In addition, once one optimal dose of DHEA was given, the amount of Asbestos from these tumors decreased very significantly (30 approximately 99% reduction) with marked increase in urine Asbestos. One optimal dose of special Cilantro tablet reduced more Asbestos than DHEA or (+) Qi Gong Energy Stored Paper. In addition, the application of (+) Solar Energy Stored Paper often reduces 70 approximately 99% of the Asbestos, while (+) Qi Gong Energy Stored Paper reduces 50 approximately 99% of the Asbestos.

Children with infantile autism sometimes show hyperesthesia or hypoesthesia to touch, pain, and/or temperature. To clarify the pathophysiology, we examined short-latency somatosensory evoked potentials (S-SEPs), elicited by median nerve stimulation, in 24 children with infantile autism (17 males, seven females; age range 2y 2mo-9y; mean age 4y 2mo [SD 1y 7mo]). We also evaluated relationships between S-SEP findings and clinical manifestations. Of the 24 children, 10 showed abnormal S-SEPs as follows: prolonged peak latency of N20 (n=2), extended interpeak latency of P13/14-N20 (n=7), appearance of a giant SEP (n=1), and a more than twofold right hemispheric peak-to-peak amplitude predominance of N20-P25 (n=5). In addition, a peak-to-peak amplitude of N20-P25 elicited by left median nerve stimuli was significantly higher than that obtained with right median nerve stimuli, which indicated right hemispheric hyperactivity relative to the left (p=0.008). Infantile autism is frequently associated with somatosensory abnormalities and right hemispheric hyperactivity relative to the left, especially in the primary somatosensory area. This is believed to contribute to the pathophysiology of infantile autism, especially the idiopathic form.

Although sensory problems, including unusual tactile sensitivity, are heavily associated with autism, there is a dearth of rigorous psychophysical research. We compared tactile sensation in adults with autism to controls on the palm and forearm, the latter innervated by low-threshold unmyelinated afferents subserving a social/affiliative submodality of somatosensation. At both sites, the groups displayed similar thresholds for detecting light touch and innocuous sensations of warmth and cool, and provided similar hedonic ratings of the pleasantness of textures. In contrast, increased sensitivity to vibration was seen in the autism group on the forearm, along with increased sensitivity to thermal pain at both sites. These findings suggest normal perception along with certain areas of enhanced perception in autism, consistent with previous studies.

The recent development of genetic databases and biobanks in a number of countries reflects scientist's beliefs in the future health benefits to be derived from genetic research. The NEPSYBANK is a national program of the Hungarian Clinical Neurogenetic Society with comprehensive participation of the Neurology and Psychiatry Departments of Medical Universities and the National Institute of Psychiatry and Neurology. The NEPSYBANK forms a part of the national biobank project (www.biobank.hu). The goal is to establish nationwide collaboration and common biobanking standards on quality, access, and protection of integrity in the field of neurology and psychiatry. Biological materials and databases are already collected in stroke, epilepsy, multiple sclerosis, motoneuron diseases, dementia, movement disorders, schizophrenia, and alcohol addiction. In peripheral neuropathies, neuropathic pain syndromes, muscle diseases, migraine, myasthenia gravis, depression, panic disease, anxiety, autism, and software development is in progress. The resources have been expanded by continued prospective collection of samples and data and important bottlenecks in sample purification, sample retrieval, in protection of the integrity of the research participants, as well as in guaranteeing the security and confidentiality of the participant's information have been harmonized. The development of uniform consent management, comprehensive sample overview and quality standards for health care-related biobanking may provide a unique opportunity for Hungary in molecular clinically oriented research. The program is a diseased-based research biobank with comprehensive collection of phenotypic and environmental information as well as biobanking of DNA, RNA or buffy coat, plasma, and erythrocytes stored at -80 degrees C. The biobank has a neuropathological part as well: storing conventional pathology and biopsy specimens. The analytical and informational demands being created by biobanking requires a "connectivity of community" that has not traditionally been present in the life sciences. As you put more resources into something, your silos tend to become taller, and we need to avoid this. The life science and healthcare community should be ignored working in individual "silos."

The biasing effect of pain sensitivity information and the impact of facial activity on observers' judgements of pain intensity of children with autism were examined. Observers received information that pain experience in children with autism is either the same as, more intense than, or less intense than children without autism. After viewing six video clips of children with autism undergoing venepuncture, observers estimated pain intensity using a visual analogue scale. Facial activity as coded by Chambers et al. (Child Facial Action Coding System Revised Manual, 1996) had a significant impact on observers' estimates of pain intensity; pain sensitivity information did not. These results have important implications for the assessment and management of pain in children with autism.

Rett Syndrome, an X-linked dominant neurodevelopmental disorder characterized by regression of language and hand use, is primarily caused by mutations in methyl-CpG-binding protein 2 (MECP2). Loss of function mutations in MECP2 are also found in other neurodevelopmental disorders such as autism, Angelman-like syndrome and non-specific mental retardation. Furthermore, duplication of the MECP2 genomic region results in mental retardation with speech and social problems. The common features of human neurodevelopmental disorders caused by the loss or increase of MeCP2 function suggest that even modest alterations of MeCP2 protein levels result in neurodevelopmental problems. To determine whether a small reduction in MeCP2 level has phenotypic consequences, we characterized a conditional mouse allele of Mecp2 that expresses 50% of the wild-type level of MeCP2. Upon careful behavioral analysis, mice that harbor this allele display a spectrum of abnormalities such as learning and motor deficits, decreased anxiety, altered social behavior and nest building, decreased pain recognition and disrupted breathing patterns. These results indicate that precise control of MeCP2 is critical for normal behavior and predict that human neurodevelopmental disorders will result from a subtle reduction in MeCP2 expression.

Autism is a severe behavioral disorder characterized by pervasive impairments in social interactions, deficits in verbal and non-verbal communication, and stereotyped behaviors, with a four times higher incidence in boys than in girls. The core symptoms are frequently accompanied by a spectrum of neurobehavioral and immunological derangements, including: aberrant sensitivity to sensory stimulation, anxiety, and decreased cellular immune capacity. Recently, a new potential rodent model of autism induced by prenatal exposure to valproic acid (VPA rats) has been proposed. In order to determine if gender has an influence on alterations observed in VPA rats, male and female rats have been evaluated in a battery of behavioral, immunological, and endocrinological tests. A plethora of aberrations has been found in male VPA rats: lower sensitivity to pain, increased repetitive/stereotypic-like activity, higher anxiety, decreased level of social interaction, increased basal level of corticosterone, decreased weight of the thymus, decreased splenocytes proliferative response to concanavaline A, lower IFN-gamma/IL-10 ratio, and increased production of NO by peritoneal macrophages. Female VPA rats exhibited only increased repetitive/stereotypic-like activity and decreased IFN-gamma/IL-10 ratio. Sexual dimorphism characteristics for measured parameters have been observed in both groups of animals, except social interaction in VPA rats. Our results confirm existence of similarities between the observed pattern of aberrations in VPA rats and features of disturbed behavior and immune function in autistic patients, and suggest that they are gender-specific, which is intriguing in light of disproportion in boys to girls ratio in autism.
