Background: Lung disease in patients with famHiat dys-autonomia is caused mainly by recurrent aspiration of gastric contents, food and liquids swallowed incorrectly.

Objective: To describe chest computed tomography findings in patients with familial dyautonomia.

Methods: A retrospective analysis of chest CT findings was performed for 34 FD patients (15 females, 19 males) with a mean age of 18± 12.8 years.

Results: The CT revealed bronchial wall thickening (in 94% of the patients), atelectasis (in 73%), ground glass opacities (in 53%), focal hyperinflation (in 44%), fibrosis (in 29%) and bronchiectasis (in 26%). The extrapulmonary abnormalities were scoliosis (79%) and esophageal dilatation (35%). Silent fractures were noted in two vertebral bodies and one rib.

Conclusions: Pulmonary changes were consistent with chronic inflammation in the bronchi and interstitial tissues. Ground  glass opacities and fibrosis support the theory that these changes could be due to gastric aspiration. Bronchiectasis is less frequent. Esophageal dilatation with fluid overflow adds to aspiration. Fractures can be asymptomaflc and are often missed.

Background: Familial dysautonomia is a genetic disease in which there is a defect in the autonomic and sensory nervous systems. These systems have a major role in the reproductive system.

Objective: To study the inter-relationship of autonomic and sensory dysfunction and gynecological function.

Methods: The gynecological histories of 48 women with familial dysautonomia were analyzed retrospectively. Their mean age was 22.25 years (range 12-47). Thirty-three women (65%) were available for further questioning and investigation of hormonal status.

Results: Menarche had occurred in 32 of the 48 (66.7%). Their average age of menarche was significantly delayed as compared to their unaffected mothers (15.5 vs. 13.6 years respectively, P=0.002). The most prominent finding was the very high prevalence, 81.2%, of premenstrual symptoms. Seven of 26 had premenstrual syndrome symptoms of dysautonomic crisis. Blood sex hormone levels were normal in 27 of the 33 patients studied. None reached natural menopause. One patient had adenomyosis, and another, dysgerminoma. Three patients became pregnant and delivered healthy infants.

Conclusion: Menarche is delayed in women with FD, and the physiological monthly hormonal fluctuations may disturb autonomic homeostasis sufficiently to precipitate dysautonomic crisis.
