The Holt-Oram syndrome, first described in 1960, consists of non-cyanotic congenital heart disease, usually an atrial septal defect, arrhythmias and malformations of the upper limbs affecting the radial segment. The transmission of the syndrome is autosomal dominant with almost complete penetrance. The authors report the localisation of a genetic abnormality of the Holt-Oram syndrome on the long arm of chromosome 12 (12q21-q3) by analysis of linkage in 9 multiplex families (Zmax = 8.19 at locus D12S354). Multipoint analysis showed a genetic interval of 7 centimorgans containing a gene of the Holt-Oram syndrome between loci D12S84 and D12S79 (multipoint lod score, 10 g base 10 = 8.96). In situ hybridization of artificial yeast chromosomes containing the surrounding markers showed that a gene of the Holt-Oram syndrome is located in 12q23-q24. The genetic heterogeneity was demonstrated in 3 families of the Holt-Oram syndrome with polydactyly or without cardiac disease (homog-test: chi 2 = 13.28; p = 0.0001). The localisation of a gene of the Holt-Oram syndrome is, to the authors' knowledge, the first chromosomal localisation of a cardiac malformation with septal defects in man. The identification of this gene should open wide perspectives for genetic research of cardiac morphogenesis and clarify the molecular mechanisms which govern cardiac septation during embryogenesis.

Ellis-van Creveld syndrome (EVC) is an autosomal recessive disorder characterized by disproportionate dwarfism, polydactyly, and congenital heart disease. This rare disorder is found with increased frequency among the Old Order Amish community in Lancaster County, Pennsylvania. We have used linkage analysis to localize the gene responsible for the EVC phenotype in nine interrelated Amish pedigrees and three unrelated families from Mexico, Ecuador, and Brazil. We now report the linkage for the Ellis-van Creveld syndrome gene to markers on the distal short arm of human chromosome 4, with Zmax = 6.91 at theta = 0.02 for marker HOX7, in a region proximal to the FGFR3 gene responsible for the achondroplasia phenotype.

This report describes three elderly patients with mucosal form of American tegumentary leishmaniasis associated with chronic cardiopathy. Due to the known toxicity of classical drugs with activity against Leishmania sp., the patients received three oral courses of azithromycin therapy in single 500 mg daily dose during ten days, every other month. All lesions healed after the third series. One of the patients relapsed and a new series of azithromycin was prescribed. Azithromycin may be an alternative drug for the treatment of leishmaniasis in special situations due to its optimal mucosal and intraphagocyte concentration, single daily posology, high tolerance and oral administration. The mechanism of this drug on Leishmania sp. is unknown at present.

Comorbidities, dietary supplement use, and prescription drug use may negatively (or positively) affect mental health in cardiovascular patients. Although the significance of mental illnesses, such as depression, anxiety, and schizophrenia, on cardiovascular disease is well documented, mental illnesses resulting from heart disease are not well studied. In this paper, we introduce the risk factors of mental illnesses as an exploratory study and develop a prediction framework for mental illness that uses comorbidities, dietary supplements, and drug usage in heart disease patients. Particularly, the data used in this study consist of the records of 68,647 patients with heart disease, including the patient's mental illness information and the patient's intake of dietary supplements, antibiotics, and comorbidities. Patients in age groups <61, gender differences, and drug intakes, such as Azithromycin, Clarithromycin, Vitamin B6, and Coenzyme Q10, were associated with mental illness. For predictive modeling, we consider applying various state-of-the-art machine learning techniques with tuned parameters and finally obtain the following: Depression: 78.01% accuracy, 79.13% sensitivity, 72.65% specificity, and 86.26% Area Under the Curve (AUC). Anxiety: 82.93% accuracy, 82.86% sensitivity, 83.35% specificity, and 88.45% AUC. Schizophrenia: 87.59% accuracy, 87.70% sensitivity, 85.14% specificity, and 92.73% AUC. Disease: 86.63% accuracy, 95.50% sensitivity, 77.76% specificity, and 91.59% AUC. From the results, we conclude that using heart disease information, comorbidities, dietary supplement use, and antibiotics enables us to accurately predict the mental health outcome.
