Autoimmune polyglandular syndrome is characterized by a failure of multiple endocrine organs and the presence of circulating organ-specific autoantibodies targeted against the failing organs. Here we describe a patient with autoimmune polyglandular syndrome type I with the endocrine manifestations of hypoparathyroidism, adrenocortical insufficiency, and insulin-dependent diabetes mellitus. Long-standing hypoparathyroidism led to extensive calcification of the basal ganglia which resulted in the clinical presentation of an extrapyramidal movement disorder (choreoathetotic and hemiballistic hyperkinesia of the left extremities). Interestingly, parallel to rehydration and the initiation of cortisol replacement therapy a complete reversion of the hyperkinetic signs was achieved. This case shows a rare multiendocrine organ failure with complex metabolic interactions resulting in marked neurological signs. Furthermore, this case demonstrates for the first time that a hyperkinetic syndrome--most likely due to hypoparathyroidism-induced basal ganglia calcification--can be reversed solely by adequate treatment of the concomitant endocrine failures.

Peer relationships, social skills, self-esteem, parental psychopathology, and family functioning of children with Tourette's disorder and a chronic disease control group of children with diabetes mellitus were compared. Children with Tourette's disorder had poorer peer relationships than their classmates and were more likely to have extreme scores reflecting increased risk for peer relationship problems than children with diabetes mellitus, but did not report self-esteem problems or social skills deficits. Measures of peer relationships were not related to severity or duration of tics. Children with Tourette's disorder and Attention Deficit Hyperactivity Disorder were at increased risk for poor peer relationships. The psychosocial problems of children with Tourette's disorder do not appear to be the generic result of having a chronic disease.

Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability, whereas deficiencies of DHA are associated with deficits in learning. DHA is taken up by the brain in preference to other fatty acids. The turnover of DHA in the brain is very fast, more so than is generally realized. The visual acuity of healthy, full-term, formula-fed infants is increased when their formula includes DHA. During the last 50 years, many infants have been fed formula diets lacking DHA and other omega-3 fatty acids. DHA deficiencies are associated with foetal alcohol syndrome, attention deficit hyperactivity disorder, cystic fibrosis, phenylketonuria, unipolar depression, aggressive hostility, and adrenoleukodystrophy. Decreases in DHA in the brain are associated with cognitive decline during aging and with onset of sporadic Alzheimer disease. The leading cause of death in western nations is cardiovascular disease. Epidemiological studies have shown a strong correlation between fish consumption and reduction in sudden death from myocardial infarction. The reduction is approximately 50% with 200 mg day(-1)of DHA from fish. DHA is the active component in fish. Not only does fish oil reduce triglycerides in the blood and decrease thrombosis, but it also prevents cardiac arrhythmias. The association of DHA deficiency with depression is the reason for the robust positive correlation between depression and myocardial infarction. Patients with cardiovascular disease or Type II diabetes are often advised to adopt a low-fat diet with a high proportion of carbohydrate. A study with women shows that this type of diet increases plasma triglycerides and the severity of Type II diabetes and coronary heart disease. DHA is present in fatty fish (salmon, tuna, mackerel) and mother's milk. DHA is present at low levels in meat and eggs, but is not usually present in infant formulas. EPA, another long-chain n-3 fatty acid, is also present in fatty fish. The shorter chain n-3 fatty acid, alpha-linolenic acid, is not converted very well to DHA in man. These longchain n-3 fatty acids (also known as omega-3 fatty acids) are now becoming available in some foods, especially infant formula and eggs in Europe and Japan. Fish oil decreases the proliferation of tumour cells, whereas arachidonic acid, a longchain n-6 fatty acid, increases their proliferation. These opposite effects are also seen with inflammation, particularly with rheumatoid arthritis, and with asthma. DHA has a positive effect on diseases such as hypertension, arthritis, atherosclerosis, depression, adult-onset diabetes mellitus, myocardial infarction, thrombosis, and some cancers.

Cardiovascular morbidity and mortality are increased in acromegaly. In fact, GH and IGF-I excess induces a specific cardiomyopathy. The early stage of acromegaly is characterized by the hyperkinetic syndrome (high heart rate and increased systolic output). Frequently, concentric biventricular hypertrophy and diastolic dysfunction occur in acromegaly, leading to an impaired systolic function ending in heart failure if the disease is untreated or unsuccessfully untreated. Besides, abnormalities of cardiac rhythm and of valves have been also described in acromegaly. The coexistence of other complications, such as arterial hypertension and diabetes, aggravates the acromegalic cardiomyopathy. The suppression of GH/IGF-I following an efficacious therapy could decrease left ventricular mass and improve cardiac function. In conclusion, a careful evaluation of cardiac function, morphology and activity seems to be mandatory in acromegaly.

Cardiovascular disease is claimed to be one of the most severe complications of acromegaly, contributing significantly to mortality in this disease. In fact, an excess of growth hormone (GH) and insulin-like growth factor 1 (IGF-I) causes a specific derangement of cardiomyocytes, leading to abnormalities in cardiac muscle structure and function, inducing a specific cardiomyopathy. In the early phase of acromegaly the excess of GH and IGF-I induces a hyperkinetic syndrome, characterized by increased heart rate and increased systolic output. Concentric hypertrophy is the most common feature of cardiac involvement in acromegaly, found in more than two thirds of patients at diagnosis. This abnormality is commonly associated with diastolic dysfunction and eventually with impaired systolic function ending in heart failure, if the GH/IGF-I excess is left untreated. In addition, abnormalities of cardiac rhythm and of heart valves have also been described in acromegaly. The coexistence of other complications, such as arterial hypertension and diabetes mellitus, aggravates acromegalic cardiomyopathy. Successful control of acromegaly induces a decrease in left ventricular mass and an improvement in diastolic function, while the effects of GH/IGF-I suppression on systolic function are more variable. However, since cardiovascular alterations in young patients with short disease duration are milder than in those with longer disease duration, it is likely to be easier to reverse and/or arrest acromegalic cardiomyopathy in young patients with early-onset disease. In conclusion, careful assessments of cardiac function, morphology, and activity are required in patients with acromegaly. An early diagnosis and prompt effective treatment are important in order to reverse acromegalic cardiomyopathy.

Aggression is a common symptom of many psychiatric disorders including attention deficit hyperactivity disorder, oppositional defiant disorder, conduct disorder, Tourette's disorder, mood disorders (including bipolar disorder), substance-related disorders, alcohol-related disorders, mental retardation, pervasive developmental disorders, intermittent explosive disorder and personality disorders (particularly antisocial personality disorder). Many forms of organic brain disorders may present with aggressive behavior. Aggression is common in some epileptic patients and some endocrinological diseases (e.g., diabetes and hyperthyroidism) may be associated with aggressive behavior. Physicians need to rule out many medical and psychiatric disorders before diagnosing aggressive behavior. A thorough diagnostic work up is the most important step in determining the nature of comorbid disorders associated with the behavioral problem. Structured interviews and rating scales completed by patients, parents, teachers and clinicians may aid the diagnosis and provide quantification for the change process related to treatment. The integration of medication, individual and family counseling, educational and psychosocial interventions including the school and community, may increase the effectiveness of interventions. Due to the common association of aggression and disruptive behaviors with attention deficit hyperactivity disorder, psychostimulants including new generation long-acting medications and other nonstimulant medications are considered the drug of choice for managing aggressive behavior and disruptive behavior disorders. Severe aggressive behavior not responding to these medications may require the single or combined use of mood regulators including lithium and/or antispychotic medications. Drugs such as risperidone (Risperdal, Janssen-Cilag) have documented effectiveness and safety in children and adolescents, and can be used in treatment.

Attentional impairments in children occur in the context of both developmental and acquired disorders involving the central nervous system (CNS) and may have implications for ongoing development, potentially impeding cognitive, educational, and behavioral functions. Using a continuous performance paradigm (CPT), this study compared attentional profiles of children with developmental and acquired conditions impacting on the CNS: (i) attention deficit-hyperactivity disorder (ADHD: n=27); (ii) moderate traumatic brain injury (TBI: n=41); (iii) acute lymphoblastic leukemia (n=31); and (iv) insulin-dependent diabetes mellitus (n=39). A healthy control group (n=46) was also examined. Groups were compared on measures of sustained attention, selective attention, and response inhibition. In addition, measures of performance variability and deterioration and processing speed were examined. Results showed that children with ADHD exhibited global and severe attentional impairments in contrast to all other groups. Children with moderate TBI displayed mild attentional difficulties, restricted to selective and sustained attention domains. In conclusion, although CPT parameters differentiated the ADHD group from all others, a disorder-specific profile was not observed.

Acromegaly is characterized by an increased cardiovascular morbidity and mortality. In fact, growth hormone and insulin-like growth factor-I excess induces a specific cardiomyopathy. The heart is involved from the very early stages of the disease in which the hyperkinetic syndrome (high heart rate and increased systolic output) takes place. Frequently, if the disease is untreated for many years or unsuccessfully treated, concentric biventricular hypertrophy and diastolic dysfunction can develop and, at least, lead to diastolic congestive heart failure. Rhythm disturbances and valve dysfunction are also frequently described in acromegaly. The coexistence of other complications, such as diabetes and arterial hypertension, can induce the worsening of acromegalic cardiomyopathy. Control of acromegaly by surgery or pharmacotherapy could improve cardiovascular morbidity thanks to decreasing left ventricular mass and reducing cardiac dysfunction. In conclusion, an early diagnosis and a careful evaluation of cardiac function, morphology and activity seem to be mandatory in acromegaly.

Dirty electricity is a ubiquitous pollutant. It flows along wires and radiates from them and involves both extremely low frequency electromagnetic fields and radio frequency radiation. Until recently, dirty electricity has been largely ignored by the scientific community. Recent inventions of metering and filter equipment provide scientists with the tools to measure and reduce dirty electricity on electrical wires. Several case studies and anecdotal reports are presented. Graham/Stetzer (GS) filters have been installed in schools with sick building syndrome and both staff and students reported improved health and more energy. The number of students needing inhalers for asthma was reduced in one school and student behavior associated with ADD/ADHD improved in another school. Blood sugar levels for some diabetics respond to the amount of dirty electricity in their environment. Type 1 diabetics require less insulin and Type 2 diabetics have lower blood sugar levels in an electromagnetically clean environment. Individuals diagnosed with multiple sclerosis have better balance and fewer tremors. Those requiring a cane walked unassisted within a few days to weeks after GS filters were installed in their home. Several disorders, including asthma, ADD/ADHD, diabetes, multiple sclerosis, chronic fatigue, fibromyalgia, are increasing at an alarming rate, as is electromagnetic pollution in the form of dirty electricity, ground current, and radio frequency radiation from wireless devices. The connection between electromagnetic pollution and these disorders needs to be investigated and the percentage of people sensitive to this form of energy needs to be determined.

Medications are administered every day in schools across the country. Researchers and clinicians have studied school nurses' and educators' experiences with medication administration, but not the experiences of children or their parents. This study examined medication administration from the child and parent perspectives to (a) determine problems children experience with medicines at school, (b) clarify risk factors for medication errors, and (c) examine the perceived impact of medication errors on school performance and social relationships. Participants included children ages 8 to 18 years (n=157) being treated at a large Midwestern Children's Hospital in diabetes, asthma, and Attention Deficit Hyperactivity Disorder (ADHD) clinics. Findings suggest that forgetting a dose and running out of medication were the most common problems. Missing a dose was more frequent in students with ADHD than in students with diabetes or asthma. Medication nonadherence at school, which includes medication administration errors such as missing a dose, may potentially lead to a variety of educational, social/emotional, and physical consequences. These results indicate that the impact of missing medication on children with ADHD appeared to have a greater effect on schoolwork and friendships, while the physical consequences appeared to vary widely based on health condition. Interestingly, children with more self-responsibility for medications were less likely to report medication errors. School nurses will want to include students when planning for medication management at school.
