We report for the first time from the Arabian Gulf area 3 patients with arthrogryposis multiplex congenita, cholestasis and renal tubular dysfunction from a Saudi family with 2 other siblings and 3 cousins who possibly died with a similar clinical picture. We also document for the second time in literature other findings in this syndrome including cerebral abnormalities (hypoplastic corpus callosum), congenital heart disease and nerve deafness. We suggest that some of these cases might benefit from ursodeoxycholic acid therapy. We believe that this autosomal recessive disorder is possibly under-diagnosed in this region with a high consanguineous marriage rate.

CHARGE association is a non-random occurrence of congenital malformations including coloboma, heart disease, choanal atresia, retarded growth and/or retarded development, genital hypoplasia, ear anomalies and/or deafness. The cause of this association remains unknown. Various genetic mechanisms have been proposed, including a contiguous gene syndrome but, so far, no recurrent locus has been identified. To address this question, we decided to perform a comparative genomic hybridization (CGH) study on a cohort of 27 patients with CHARGE association and a normal standard karyotype. We found two chromosomal anomalies: a der(9)t(9;13) derived from a paternal translocation and a der(6)t(4;6) of unknown origin. This suggests that chromosome imbalances may well mimic CHARGE association. Therefore patients with CHARGE association must be carefully tested with classical and molecular cytogenetic techniques to detect a potential chromosome imbalance. It is expected that more stringent diagnostic criteria of CHARGE association could define a more homogeneous group of patients where a single genetic cause might be identified.

Rubella during pregnancy can lead to miscarriages and stillbirths, while Congenital Rubella Syndrome results in children with severe birth defects such as congenital heart disease, cataracts, deafness, mental retardation, and microcephaly. Cost-benefit studies in several Caribbean countries indicate that investing in the eradication of rubella will bring tangible benefits within 5 years, given the high cost of care and rehabilitating children with Congenital Rubella Syndrome. If a rubella eradication program is not implemented, a large number of Congenital Rubella Syndrome cases could develop over the next 15 years. An eradication program would cost only an estimated 7% of the cost of providing care and rehabilitating rubella cases. The Council for Human and Social Development will make every possible effort to eliminate rubella and prevent the occurrence of new cases of Congenital Rubella Syndrome in the Caribbean community by the end of 2000. Furthermore, the council urges the Pan American Health Organization (PAHO) to coordinate the mobilization of resources and technical support toward eradicating rubella.

LEOPARD syndrome is a neuroectodermal disorder presumed to result from an abnormality in neural crest cells. The acronym 'LEOPARD' is derived from the clinical features which include multiple lentigines, electrocardiographic abnormalities, ocular hypertelorism, pulmonary stenosis, abnormal genitalia, retarded growth, and deafness. Given the multisystem nature of the disease process, several issues may affect the perioperative care of these patients. Of primary importance are associated conditions of the cardiovascular system including congenital heart disease, conduction disturbances, and progressive hypertrophic obstructive cardiomyopathy. The authors present a 4-year old boy who presented for anaesthetic care for repair of a ventricular septal defect and pulmonary valvotomy for congenital pulmonary stenosis. The potential perioperative implications of LEOPARD syndrome are discussed.

Between 25,000 and 75,000 new cases of angina refractory to maximal medical therapy and standard coronary revascularization procedures are diagnosed each year. In addition, heart failure also places an enormous burden on the U.S. health care system, with an estimated economic impact ranging from $20 billion to more than $50 billion per year. The technique of counterpulsation, studied for almost one-half century now, is considered a safe, highly beneficial, low-cost, noninvasive treatment for these angina patients, and now for heart failure patients as well. Recent evidence suggests that enhanced external counterpulsation (EECP) therapy may improve symptoms and decrease long-term morbidity via more than 1 mechanism, including improvement in endothelial function, promotion of collateralization, enhancement of ventricular function, improvement in oxygen consumption (VO2), regression of atherosclerosis, and peripheral training effects similar to exercise. Numerous clinical trials in the last 2 decades have shown EECP therapy to be safe and effective for patients with refractory angina with a clinical response rate averaging 70% to 80%, which is sustained up to 5 years. It is not only safe in patients with coexisting heart failure, but also is shown to improve quality of life and exercise capacity and to improve left ventricular function long-term. Interestingly, EECP therapy has been studied for various potential uses other than heart disease, such as restless leg syndrome, sudden deafness, hepatorenal syndrome, erectile dysfunction, and so on. This review summarizes the current evidence for its use in stable angina and heart failure and its future directions.

As our knowledge and abilities in molecular genetics continues to expand, so does our ability to detect certain conditions/traits prenatally; however, it is unknown if this increase in scientific ability will be utilized by the consumers of genetic services. Our study gauges the consumers' opinion towards reproductive testing for diseases and enhancements. Prior to their initial visit with a genetic counselor, patients were asked to participate in a survey. These consumers were asked to indicate traits and conditions for which they would choose reproductive genetic testing. The majority of respondents would elect to have prenatal genetic testing for mental retardation (75%), deafness (54%), blindness (56%), heart disease (52%), and cancer (51%). Our results indicated that 49.3% would choose testing for a condition that resulted in death by 5 years of age, whereas only 41.1%, 24.9%, and 19% would choose testing for conditions that results in death by 20, 40, and 50 years of age, respectively. Most respondents did not desire testing for enhancements (e.g. 13% would choose testing for superior intelligence). Our study suggests that consumers desire more reproductive genetic testing than what is currently offered; however, their selection of tests suggests self-imposed limits on testing.

Townes-Brocks syndrome (TBS) is an autosomal dominant disorder characterized by external ear anomalies with sensorineural hearing loss, limb anomalies, renal and anorectal malformations. TBS is caused by mutations in SALL1, a gene mapped to chromosome 16q12.1. We report three generations of a family with SALL1 c.1326delC (p.Ser442fs) mutation, showing increased clinical severity over generations. The members of the first generation demonstrated polydactyly and deafness. In the second generation, the mother and uncle of the proband additionally had renal and/or anal anomalies. The proband in the third generation showed the most severe symptoms including congenital heart disease. Increase in clinical severity in successive generations in TBS cannot be explained genetically. There is wide clinical variation in TBS; however, most affected parents are usually mildly affected and may have similarly or more severely affected children. Social and/or physical bias at reproduction may contribute to an apparent increase in clinical severity over generations in TBS.

Within endocrinology, the long-term management of Turner syndrome (TS) in adults is fast becoming a specialist subject in its own right. The complications of TS can affect every system in the body, and the main reason why it falls to endocrinologists to coordinate health care is that many features are clearly within the endocrine remit: hypothyroidism, diabetes, hypertension, osteoporosis, hypogonadism. Endocrinologists as general physicians can often cover surveillance of problems in other areas such as congenital heart disease, inflammatory bowel disease and deafness, calling upon specialist input only if the need arises. In this way, a simple 'one stop shop' can offer a well-woman service for women with TS in a cost-effective manner. Such a service requires a multidisciplinary approach.

The association between diabetes mellitus and hypokinetic cardiomyopathy is frequent. We report a case of diabetes and hypokinetic cardiopathy in a 40-year-old man which led to the hypothesis of maternally inherited diabetes and deafness (MIDD) due to a mitochondrial disease. This diagnosis was confirmed by genetic testing which showed a DNA A3243G mutation in the mitochondria, the prevalence of which is 1-2% in diabetes mellitus. Cardiac abnormalities are frequent (18-34% of patients depending on the series) and the co-existence of left ventricular hypertrophy and systolic dysfunction is suggestive of this disease. Some authors have proposed co-enzyme Q as a treatment to improve the left ventricular ejection fraction and insulin secretion.

We report the case of a 15-year-old girl who presented to a pediatric endocrinology clinic for delayed puberty with no signs of secondary sexual development. Her past medical history was significant for bilateral colobomas, inner-ear anomalies, hearing loss, and anosmia. Genetic testing revealed a novel de novo mutation in the CHD7 gene, one of the causative genes in CHARGE syndrome (coloboma, heart disease, choanal atresia, retarded growth and development and/or central nervous system anomalies, genital anomalies and/or hypogonadism, and ear anomalies and/or deafness). We review the distinction between hypogonadotrophic hypogonadism and hypergonadotrophic hypogonadism and discuss the availability of molecular genetic testing for idiopathic hypogonadotrophic hypogonadism. CHD7 mutations have also been found in some patients with Kallmann syndrome, hypogonadotrophic hypogonadism, and anosmia, and we discuss the overlap between this syndrome and CHARGE syndrome. With the increased availability of genetic testing for a variety of disorders, it is important for pediatricians to become familiar with interpreting genetic test results. Finally, we illustrate that Bayes' theorem is a useful statistical tool for interpreting novel missense mutations of unknown significance.
