Radioulnar Synostosis is the abnormal development of the radio-ulnar joint.

Radioulnar Synostosis is the abnormal development of the radio-ulnar joint. In this rare condition there is congenital fusion of the proximal ends of the radius and ulna, which severely restricts supination of the forearm and, consequently, puts unusual strain on the elbow and shoulder. In about 60 percent of cases, involvement is bilateral.

Severely restricted supination means that one cannot take change — the palm cannot be made flat, so the coins fall. It is impossible to touch the shoulders with the thumbs or to hold silverware the way other people do. It is also impossible to play bar chords on a guitar or throw a football properly. Club foot often occurs with this genetic anomaly and sufferers should be checked for heart and kidney problems.

Surgical intervention is possible but rarely successful. The bones usually re-fuse and the best that can generally be done is to reset the arms so that when the bones fuse back together the neutral position is more supinated. Blood supply in the arm is often jeopardized by surgery.

ROHHAD Syndrome (Rapid-onset Obesity with Hypothalamic dysfunction, Hypoventilation and Autonomic Dysregulation) is a rare disorder in which affects the governace of proper breathing.

Rapid-onset Obesity with Hypothalamic dysfunction, Hypoventilation and Autonomic Dysregulation (ROHHAD syndrome) is a very rare disease affecting approximately only 35 cases worldwide. Patients with ROHHAD,as well as patients with Congenital Central Hypoventilation Syndrome, CCHS, have damaged the mechanism governing the proper breathing. ROHHAD syndrome is a disease that is potentially lethal and incurable.

Hypothalamic Dysfunction Failed Growth Hormone Stimulation Polydipsia Hypernatremia Hyperprolactinemia Hyperphagia Diabetes Insipidus Respiratory Manifestations Alveolar Hypoventilation Cardiorespiratory Arrest Reduced Carbon Dioxide Ventilatory Response Obstructive sleep apnea Autonomic Dysregulation Ophthalmologic Manifestations Thermal Dysregulation Gastrointestinal Dysmotility Altered Perception of Pain Altered Sweating Cold Hands and Feet Tumor of Neural Crest Origin Abnormal Brain MRI Scans Seizure Enuresis Hypotonia

There are no tests for ROHHAD at this time. Usually child exhibits multiple symptoms that may go undiagnosed until respiratory arrest occurs.

There are no treatments or cures for ROHHAD.

Raynaud’s Disease is a disorder characterized by some areas of the body, including fingers, toes, the nose, and ears to feel numb and cool in response to cold temperatures or stress.

Raynaud’s Disease is a disorder characterized by some areas of the body (fingers, toes, nose, ears, etc.) feeling numb and cool in response to cold temperatures or stress. This is caused by limited blood circulation to the affected areas due to the narrowing of arteries that supply blood to your skin.

Retroperitoneal Fibrosis is an ideopathic auto-immune disorder that causes scar tissue to form in the the abdomen and wrap itself around the abdominal aorta. It can grow in thickness and length, and extend to vital organs, compromising their functions and causing pain.

Prendisone is among the few drugs that have been shown to slow progression of the disease.
