Retinoblastoma

Retinoblastoma (Rb) is a malignant tumor of the developing retina that occurs in children, usually before age five years. Rb develops from cells that have cancer-predisposing variants in both copies of RB1. Rb may be unifocal or multifocal. About 60% of affected individuals have unilateral Rb with a mean age of diagnosis of 24 months; about 40% have bilateral Rb with a mean age of diagnosis of 15 months. Heritable retinoblastoma is an autosomal dominant susceptibility for Rb. Individuals with heritable retinoblastoma are also at increased risk of developing non-ocular tumors. [from GeneReviews]

Disorder of endocrine system

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include. -Growth and development. -Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature . -Sexual function. -Reproduction. -Mood. If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels. In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.  [from MedlinePlus]

Disorder of adrenal gland

The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones. In Cushing's syndrome, there's too much cortisol, while with Addison's disease, there is too little. Some people are born unable to make enough cortisol. Causes of adrenal gland disorders include. -Genetic mutations. -Tumors including pheochromocytomas. -Infections. -A problem in another gland, such as the pituitary, which helps to regulate the adrenal gland. -Certain medicines. Treatment depends on which problem you have. Surgery or medicines can treat many adrenal gland disorders. NIH: National Institute of Child Health and Human Development.  [from MedlinePlus]
