Data are reviewed on the effects of massage therapy on infants and children with various medical conditions. The infants include: premature infants, cocaine-exposed infants, HIV-exposed infants, infants parented by depressed mothers, and full-term infants without medical problems. The childhood conditions include: abuse (sexual and physical), asthma, autism, burns, cancer, developmental delays, dermatitis (psoriasis), diabetes, eating disorders (bulimia), juvenile rheumatoid arthritis, posttraumatic stress disorder, and psychiatric problems. Generally, the massage therapy has resulted in lower anxiety and stress hormones and improved clinical course. Having grandparent volunteers and parents give the therapy enhances their own wellness and provides a cost-effective treatment for the children.

Gene duplications alter the genetic constitution of organisms and can be a driving force of molecular evolution in humans and the great apes. In this context, the study of genomic disorders has uncovered the essential role played by the genomic architecture, especially low copy repeats (LCRs) or segmental duplications (SDs). In fact, regardless of the mechanism, LCRs can mediate or stimulate rearrangements, inciting genomic instability and generating dynamic and unstable regions prone to rapid molecular evolution. In humans, copy-number variation (CNV) has been implicated in common traits such as neuropathy, hypertension, color blindness, infertility, and behavioral traits including autism and schizophrenia, as well as disease susceptibility to HIV, lupus nephritis, and psoriasis among many other clinical phenotypes. The same mechanisms implicated in the origin of genomic disorders may also play a role in the emergence of segmental duplications and the evolution of new genes by means of genomic and gene duplication and triplication, exon shuffling, exon accretion, and fusion/fission events.

Killer-cell immunoglobulin-like receptor (KIR) proteins are expressed on natural killer (NK) cells and appear important in innate and adaptive immunity. There are about 14 KIR genes on chromosome 19q13.4, composed of those that inhibit and those that activate NK cell killing. Haplotypes have different combinations of these genes meaning that not all genes are present in a subject. There are two main classes of cognate human leukocyte antigen (HLA) ligands (HLA-Bw4 and HLA-C1/C2) that bind to the inhibitory/activating receptors. As a general rule, the inhibitory state is maintained except when virally infected or tumor cells are encountered; however, both increased activation and inhibition states have been associated with susceptibility and protection against numerous disease states including cancer, arthritis, and psoriasis. Utilizing DNA from 158 Caucasian subjects with autism and 176 KIR control subjects we show for the first time a highly significant increase in four activating KIR genes (2DS5, 3DS1, 2DS1 and 2DS4) as measured by chi square values and odds ratios. In addition, our data suggests a highly significant increase in the activating KIR gene 2DS1 and its cognate HLA-C2 ligand (2DS1+C2; p = 0.00003 [Odds ratio = 2.87]). This information ties together two major immune gene complexes, the human leukocyte complex and the leukocyte receptor complex, and may partially explain immune abnormalities observed in many subjects with autism.

The scope of the present research was to study parvovirus circulation in Tbilisi population and its role in etiology of somatic pathologies. Parvovirus circulation in persons with autism and disorder of the nervous system was examined. Blood of 110 patients was examined. Among them 35 were children (up to 15 years old) and 75 adults, mainly with different somatic pathologies such as mineral metabolism disorder, allergic reactions, cystic fibrosis, cerebral palsy and autism. Almost all the children came from the so called frequently ill category and suffered from disbacteriosis. Among adults, 16 were parents of the ill children, while the rest came with hepatitis, mineral metabolism disorder of different type and psoriasis. Blood serum of 30 adults was taken as an adult control group. Their age varied from 18 to 25 years. 10 children aged 2-15 constituted a children control group. Preventive examination was made and there were practically, absolutely healthy persons. A total of 150 persons were involved in the research. Frequency of parvoviral antibody detection in the ill children and adults is much higher than in healthy individuals. Consequently, positive results for the presence of M and G immunoglobulins in children equals to 54% and 85% respectively. In adults these indicator stand at 24% and 60% respectively. At the same time in 25% and 70% of parents of positive children were found to be positive for M immunoglobulin and G immunoglobulin respectively. Thus our investigation made it clear that parvoviral infection actively circulates in Georgia. The present research did not study manifested parvoviral infection, i.e. 5th disease. If it had than the number of positive results probably would have been much higher. In autistic children presence of parvoviral infection is consistent with the literature data.

Deworming is rightly advocated to prevent helminth-induced morbidity. Nevertheless, in affluent countries, the deliberate infection of patients with worms is being explored as a possible treatment for inflammatory diseases. Several clinical trials are currently registered, for example, to assess the safety or efficacy of Trichuris suis ova in allergies, inflammatory bowel diseases, multiple sclerosis, rheumatoid arthritis, psoriasis, and autism, and the Necator americanus larvae for allergic rhinitis, asthma, coeliac disease, and multiple sclerosis. Studies in animals provide strong evidence that helminths can not only downregulate parasite-specific immune responses, but also modulate autoimmune and allergic inflammatory responses and improve metabolic homoeostasis. This finding suggests that deworming could lead to the emergence of inflammatory and metabolic conditions in countries that are not prepared for these new epidemics. Further studies in endemic countries are needed to assess this risk and to enhance understanding of how helminths modulate inflammatory and metabolic pathways. Studies are similarly needed in non-endemic countries to move helminth-related interventions that show promise in animals, and in phase 1 and 2 studies in human beings, into the therapeutic development pipeline.

We conducted a case-control study among members of Kaiser Permanente Northern California (KPNC) born between 1980 and 2003 to determine the prevalence of immune-mediated conditions in individuals with autism, investigate whether these conditions occur more often than expected, and explore the timing of onset relative to autism diagnosis. Cases were children and young adults with at least two autism diagnoses recorded in outpatient records (n=5565). Controls were children without autism randomly sampled at a ratio of 5 to 1, matched to cases on birth year, sex, and length of KPNC membership (n=27,825). The main outcomes - asthma, allergies, and autoimmune diseases - were identified from KPNC inpatient and outpatient databases. Chi-square tests were used to evaluate case-control differences. Allergies and autoimmune diseases were diagnosed significantly more often among children with autism than among controls (allergy: 20.6% vs. 17.7%, Crude odds ratio (OR)=1.22, 95% confidence interval (CI) 1.13-1.31; autoimmune disease: 1% vs. 0.76%, OR=1.36, 95% CI 1.01-1.83), and asthma was diagnosed significantly less often (13.7% vs. 15.9%; OR=0.83, 95% CI 0.76-0.90). Psoriasis occurred more than twice as often in cases than in controls (0.34% vs. 0.15%; OR=2.35, 95% CI 1.36-4.08). Our results support previous observations that children with autism have elevated prevalence of specific immune-related comorbidities.

The microorganisms that inhabit humans are very diverse on different body sites and tracts. Each specific niche contains a unique composition of the microorganisms that are important for a balanced human physiology. Microbial cells outnumber human cells by tenfold and they function as an invisible organ that is called the microbiome. Excessive use of antibiotics and unhealthy diets pose a serious danger to the composition of the microbiome. An imbalance in the microbial community may cause pathological conditions of the digestive system such as obesity, cancer and inflammatory bowel disease; of the skin such as atopic dermatitis, psoriasis and acne and of the cardiovascular system such as atherosclerosis. An unbalanced microbiome has also been associated with neurodevelopmental disorders such as autism and multiple sclerosis. While the microbiome has a strong impact on the development of the host immune system, it is suspected that it can also be the cause of certain autoimmune diseases, including diabetes or rheumatoid arthritis. Despite the enormous progress in the field, the interactions between the human body and its microbiome still remain largely unknown. A better characterization of the interactions may allow for a deeper understanding of human disease states and help to elucidate a possible association between the composition of the microbiome and certain pathologies. This review focuses on general findings that are related to the area and provides no detailed information about the case of study. The aim is to give some initial insight on the studies of the microbiome and its connection with human health.

Millions of microorganisms inhabit the human body and affect its homeostasis in multiple ways. Alterations in this microbial community have implications for the health and survival of the human hosts. It is believed that these microorganisms should be included as part of the human genome because of their influence on human physiology hence the term "microbiome" is commonly used to refer to these microbes along with their genetic make-up and their environmental interactions. In this article we attempt to provide an insight into this recently discovered vital organ of the human body which is yet to be fully explored. We herein discuss the composition and role of microbiome in human health and disease with a special emphasis in children and culture-independent techniques employed in mapping of the microbiome. Alteration in the gut microbiome has been associated with causation of several paediatric diseases like infantile colic, necrotizing enterocolitis, asthma, atopy, obesity, type -1 diabetes, and autism. Atopic dermatitis and psoriasis have also been associated with changes in the cutaneous microbiome. Respiratory microbial imbalances during infancy have been linked with wheezing and bronchial asthma. Dysbiosis in the regional microbiome has been linked with caries, periodontitis, and chronic rhinosinusitis. The future therapeutic implications of this rapidly evolving area of research are also highlighted.

The human body is colonized by millions of microorganisms named microbiota that interact with our tissues in a cooperative and non-pathogenic manner. These microorganisms are present in the skin, gut, nasal, oral cavities, and genital tract. In fact, it has been described that the microbiota contributes to balancing the immune system to maintain host homeostasis. The gut is a vital organ where microbiota can influence and determine the function of cells of the immune system and contributes to preserve the wellbeing of the individual. Several articles have emphasized the connection between intestinal autoimmune diseases, such as Crohn's disease with dysbiosis or an imbalance in the microbiota composition in the gut. However, little is known about the role of the microbiota in autoimmune pathologies affecting other tissues than the intestine. This article focuses on what is known about the role that gut microbiota can play in the pathogenesis of non-intestinal autoimmune diseases, such as Grave's diseases, multiple sclerosis, type-1 diabetes, systemic lupus erythematosus, psoriasis, schizophrenia, and autism spectrum disorders. Furthermore, we discuss as to how metabolites derived from bacteria could be used as potential therapies for non-intestinal autoimmune diseases.

With increasing numbers of children being diagnosed with neurodevelopmental disorders (NDDs) attention has been drawn to these children's physical health. We aimed to identify the prevalence of defined physical problems (epilepsy, migraine, asthma, cancer, diabetes, psoriasis, lactose intolerance, celiac disease, diarrhea, constipation, daytime enuresis, encopresis) in a nationwide population of 9- and 12-year-old twins subdivided into those with and without indications of NDDs. Parents of 28,058 twins participated in a well-validated telephone interview regarding their children's mental health and answered questions about their physical problems. The results indicate a high rate of physical problems in children with NDDs, particularly in those with indications of the presence of combinations of several NDDs.
