A total of 600 handicapped patients had dental rehabilitation under general anesthesia during an eight-year period. Handicaps included mental retardation, cerebral palsy, Down syndrome, seizure disorders, autism, cystic fibrosis, osteogenesis imperfecta, and muscular dystrophy. No significant complications developed in the majority of patients. This is attributed to thorough preoperative evaluation, appropriate anesthetic management, and vigilant postoperative observation.

The study compared the different patterns of stress reported by mothers of children with either a chronic physical illness (cystic fibrosis), a chronic psychological disorder (autism), and children without a physical or psychological disorder. Twenty-four mothers from each of these three groups completed the Questionnaire on Resources and Stress Short Form (Holroyd & Guthrie, 1986). Each clinical group exhibited different patterns of stressful response consistent with the nature of the disorder and the requirements of care imposed on the families. Autism was found to contribute significantly more to family stress than did cystic fibrosis. The number of children in the family was not a significant variable. Implications for the development of family intervention programs are discussed.

During the last 30 years the Frambu Health Centre has evolved from a summer-camp site for children with poliomyelitis to a modern information and treatment Centre for families with disabled members. Since 1976, fortnightly courses have been held for an increasing number of patients with rare, often congenital and/or hereditary disorders (anorectal anomalies, bladder extrophy, congenital heart defects, cystic fibrosis, severe diabetes, hemophilia, hip joint defects, juvenile rheumatoid arthritis, minimal brain dysfunction, muscular dystrophy, phenylketonuria, psychosis/autism, spina bifida, Huntington's chorea, osteogenesis imperfecta, retitinitis pigmentosa, a. o.). This article describes the facilities, operation, financing and staff at Frambu. An outline of the course programme is given. The contents of two research projects carried out at Frambu are described. When families with rare disorders meet for the first time, new perspectives open up. Exchange of experience and feelings, establishing lay organizations, collating and distributing information to professionals and families are some of the important results of the Frambu courses.

An 8-year-old boy with cystic fibrosis (CF), mental retardation, and autism exhibited noncompliance with respiratory treatments that were essential for the management of his CF. A treatment involving shaping cooperation while still allowing escape for aggression and avoidance behavior resulted in increases compliance with respiratory treatments and decreases in problem behavior. Treatment gains were maintained over 3 months.

As patients and parents seek more information and the threat of litigation increases, the process of informed consent has assumed greater importance. Data from large adult experiences indicate that the risk of bile duct injury, although small, is greater with laparoscopic cholecystectomy (LC) than open cholecystectomy. This complication has not yet been documented in pediatric practice, where cholecystectomy is relatively uncommon. What method do parents and patients choose if consent is truly informed? Of 57 consecutive children undergoing cholecystectomy, an open procedure was specifically indicated in 20 (previous major gastrointestinal surgery in 11, concomitant major abdominal operation in four, and complex biliary tract disease in five) and LC in two (cystic fibrosis, severe autism). The remaining 35 patients were counseled in a standard manner about the relative merits of LC versus mini-cholecystectomy (MC) and allowed to choose. Specifically, they were informed that LC offers better cosmesis, less postoperative discomfort, and a shorter hospital stay, but in adults is associated with a slightly increased rate of bile duct injury (0.3-0.5% vs. 0.2%). All MCs were performed through a 4-cm incision. Parents chose LC in 23 cases and MC in 12. The median age of both groups was similar. No surgical complications occurred, and there were no conversions in the LC group. No patient had retained stones. LC patients were discharged home after a mean of 1.7 days and MC patients after 2.3 days (0.1 > p > 0.05). If an open or laparoscopic technique is not specifically indicated and if parents/patients are fully informed, a significant minority may opt for mini-cholecystectomy.

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.

The health care needs of children with spina bifida are complex. They need specialists, generalists, and an integrated system to deliver this complex care and to align and inform all the providers. Most research in spina bifida has been focused on narrow medical outcomes; it has been noncollaborative, based on small samples of convenience, with no comparison groups, and without consistent standards of measurement. Models of health, like the World Health Organization International Classification of Functioning, Disability, and Health Model can help to broaden the scope of future research. Using methods from other pediatric conditions like the patient registry (cystic fibrosis), gene bank (autism), and collaborative research (leukemia), researchers can improve the quality of future studies. Research questions related to the process of care and to specific nonsurgical conditions associated with spina bifida are reviewed in this article.

Normal functioning of the human body requires a balance between nutritional intake and metabolism, and imbalances manifest as nutritional deficiencies or excess. Nutritional deficiency states are associated with social factors (war, poverty, famine, and food fads), medical illnesses with malabsorption (such as Crohn disease, cystic fibrosis, and after bariatric surgery), psychiatric illnesses (eating disorders, autism, alcoholism), and medications. Nutritional excess states result from inadvertent or intentional excessive intake. Cutaneous manifestations of nutritional imbalance can herald other systemic manifestations. This contribution discusses nutritional deficiency and excess syndromes with cutaneous manifestations of particular interest to clinical dermatologists.

Microarray technology, in its simplest form, allows one to gather abundance data for target DNA molecules, associated with genomes or gene-expressions, and relies on hybridizing the target to many short probe oligonucleotides arrayed on a surface. While for such multiplexed reactions conditions are optimized to make the most of each individual probe-target interaction, subsequent analysis of these experiments is based on the implicit assumption that a given experiment yields the same result regardless of whether it was conducted in isolation or in parallel with many others. It has been discussed in the literature that this assumption is frequently false, and its validity depends on the types of probes and their interactions with each other. We present a detailed physical model of hybridization as a means of understanding probe interactions in a multiplexed reaction. Ultimately, the model can be derived from a system of ordinary differential equations (ODE's) describing kinetic mass action with conservation-of-mass equations completing the system. We examine pairwise probe interactions in detail and present a model of "competition" between the probes for the target--especially, when the target is effectively in short supply. These effects are shown to be predictable from the affinity constants for each of the four probe sequences involved, namely, the match and mismatch sequences for both probes. These affinity constants are calculated from the thermodynamic parameters such as the free energy of hybridization, which are in turn computed according to the nearest neighbor (NN) model for each probe and target sequence. Simulations based on the competitive hybridization model explain the observed variability in the signal of a given probe when measured in parallel with different groupings of other probes or individually. The results of the simulations can be used for experiment design and pooling strategies, based on which probes have been shown to have a strong effect on each other's signal in the in silico experiment. These results are aimed at better design of multiplexed reactions on arrays used in genotyping (e.g., HLA typing, SNP, or CNV detection, etc.) and mutation analysis (e.g., cystic fibrosis, cancer, autism, etc.).

Ethicists contend that researchers are obliged to report genetic research findings to individual study participants when they are clinically significant, that is, when they are clinically useful or personally meaningful to participants. Yet whether such standards are well understood and can be consistently applied remains unknown. We conducted an international, cross-sectional survey of cystic fibrosis (CF) and autism genetics researchers using a quasi-experimental design to explore factors influencing researchers' judgments. Eighty percent of researchers agreed, in principle, that clinically significant findings should be reported to individual participants. Yet judgments about when a specific finding was considered clinically significant or warranted reporting varied by scientific factors (replication, robustness, intentionality, and disease context), capacity of the research team to explain the results, and type of research ethics guidance. Further, judgments were influenced by the researchers' disease community (autism or CF), their primary role (clinical, molecular, statistical) and their beliefs regarding a general reporting obligation. In sum, judgments about the clinical significance of genetic research results, and about whether they should be reported, are influenced by scientific parameters as well as contextual factors related to the specific research project and the individual researcher. These findings call into question the assumption that the conditions under which an obligation to disclose arises are uniformly understood and actionable. Adjudicating the clinical readiness of provisional data may be a responsibility better suited to evaluative experts at arms' length of the provisional data in question, rather than a responsibility imposed upon researchers themselves.
