Primary pulmonary lymphangiectasia in Noonan syndrome: apropos of an extremely rare manifestation and a brief literature review.

Noonan syndrome (NS) is a genetic multisystem disorder characterised by distinctive facial features, developmental delay, learning difficulties, short stature, congenital heart disease, renal anomalies, bleeding difficulties and lymphatic malformations. Although lymphatic dysplasias are present in 20% of patients with NS, however pulmonary lymphangiectasia has rarely been described. In this present paper, we report a 24-year-old male who was diagnosed with Noonan syndrome and primary pulmonary lymphangiectasia by using chest imaging modalities.

Vitamin D deficiency in the elderly in Athens, Greece.

Vitamin D deficiency characterized by low 25-hydroxyvitamin D [25(OH)D] levels has been found to be prevalent among the elderly in many regions of the world. To investigate the vitamin status in elderly community-living persons in Athens, we measured 25(OH)D and parathyroid hormone (PTH) in elderly persons and young blood donors during the winter and summer. The changes in these parameters in a subgroup of the elderly were studied longitudinally.
