SDD surgery decisions to be shared by physicians and parentsA shared process of decision making can be beneficial in assisting doctors and parents who face the extraordinarily complex and controversial choice when infants are born with born with genetic or anatomical anomalies in sexual development and selected for elective corrective surgery.

Difficult Decisions: Disorders of Sex Development and Surgical Intervention” is published online in the August issue of the Journal of Pediatric Endocrinology and Metabolism.

The big issue to be addressed is the absence of standard approach for infants born with sex development disorder (SDD) or with atypical sexual development.

Parents and physicians share decisions in SDD surgeryA new research paper has suggested that a shared process of decision making could assist parents and doctors who face the extraordinarily complex and controversial choice when infants are born with born with genetic or anatomical anomalies in sexual development and considered for elective corrective surgery.

Alexander Kon, senior author of the study and associate professor of pediatrics and bioethics at the UC Davis School of Medicine, said the big issue that is addressed is that there is lack of standard approach for infants born with sex development disorder (SDD) or with atypical sexual development.

Airway constriction in asthmatic women patients reduces with estrogenAccording to new bench research from the Mayo Clinic, female sex hormones could work with beta-agonists in minimizing airway constriction.

Lead student researcher, Elizabeth A. Townsend, of the Mayo Clinic Department of Physiology and Biomedical Engineering, said that it will be of interest to ascertain whether sex steroids such as estrogen and progesterone play a role in modulation of airway tone.

The findings are being presented at the ATS 2010 International Conference in New Orleans.

Gene causing puberty complications identified by researchersResearchers from the Medical College of Georgia have been able to discover chromodomain helicase DNA binding protein 7 or CHD7, a gene, which is responsible for many of the puberty-related complications.

The research team discovered that the gene is able to get mutated in a multi-system complication characterized by complications such as mental retardation and loss of hearing, which is known as the CHARGE syndrome.

The syndrome has an impairment effect on the sense of smell and can prevent production of hormones and sex steroids.

Gene responsible for triggering puberty complications discoveredA gene, chromodomain helicase DNA binding protein 7 or CHD7, has been discovered by researchers from the Medical College of Georgia. This gene is responsible for many of the known complications related with puberty.

It was found by the researchers that this gene gets mutated in CHARGE syndrome, which is a multi-system complication characterized by complications such as mental retardation and loss of hearing; the two disorders are idiopathic hypogonadotropic hypogonadism (IHH) and Kallmann syndrome.

The CHARGE syndrome was found to have an impairment effect on the smell sense and inhibits sex steroids and hormone production.

Sugar, sex steroids, and metabolic complicationsOverweight children and adults have low levels of SHGB, a protein, in their blood. This protein transports sex steroids besides regulating their entry into tissues.

Geoffrey Hammond and colleagues at the University of British Columbia, Vancouver, recently provided an explanation as to why low levels of SHGB are such a good marker of the metabolic syndrome.

This study is expected to offer implications to aid medical practitioners all over the world for understand medical disorders that increase an individual’s risk of developing type 2 diabetes and heart disease in a better manner.

Sex steroids and irritability associated with menopauseThere is a possible link between irritability and perimenopausal and postmenopausal women but there are not any study results or evidence suggesting an association.

A study examining association between menopause with sex steroids, gonadotrophins, prolactin and thyroid hormones and with samples including of 163 women, with a mean age of 55.1 years (SD = 5.7) in relation to 124 postmenopausal and 26 perimenopausal women, suggested that a high score is visible on inward and outward irritability scales in women with chronic disease.

Though not linked directly with menopause, it could have been partially influenced by the growing age of menopausal women.

The results of this study are seen by many as evidence that suggests a possible link between menopause and outward irritability.

Immune systems of mice and humans rejuvenated using a common hormoneMonash University scientists have been able to rejuvenate the immune systems of mice and humans using a common hormone.

The scientists were led by Associate Professor Richard Boyd and Dr Jayne Sutherland from the Monash Immunology and Stem Cell Laboratories. The involved scientists revitalized the thymus, which is responsible for producing the T cells needed for fighting infection but which shuts down from early childhood age.

The achievement was published in an issue of the Journal of Immunology and is expected to offer a new hope to patients with cancer, AIDS and other immunodeficiencies and for transplant patients.
