Unusual manifestations of type 1 autoimmune polyendocrinopathy.

We present a family with five members affected by Type 1 autoimmune polyendocrinopathy. All patients had chronic mucocutaneous candidiasis and dental abnormalities. Four patients had ocular abnormalities, four had hypoparathyroidism, and three had Addison's disease. The family was unusual in that all four affected females had premature ovarian failure. The ocular abnormalities included two patients with subcapsular lens opacities, one patient with asymptomatic corneal opacities, and one patient with severe bilateral iridocyclitis with cataract formation. One patient had pernicious anaemia and one had insulin dependent diabetes mellitus. All patients were negative on repeated occasions for organ specific and non-organ specific autoantibodies. Lymphocyte studies were performed in four patients. A deficiency of T suppressor cells was found in three and low normal levels were present in the fourth suggesting that the syndrome may be due to a defect in suppressor T cells.

The kinematic patterns of toe-walkers.

Children who toe-walk can pose a diagnostic problem. The differential diagnosis includes mild spastic diplegia and idiopathic toe-walking. Clinical differentiation between these two patient groups can be particularly difficult, and there are no objective diagnostic tests to assist the clinician. We assessed 50 children who toe-walk to define the kinematic patterns of lower-limb joint motion in the sagittal plane. There were 23 children with mild spastic diplegia. 22 idiopathic toe-walkers, and five normal children who were asked to toe-walk. We found characteristic patterns of knee and ankle motion that differentiated spastic diplegia from idiopathic toe-walking. Normal children asked to toe-walk had the same pattern as the idiopathic group. Gait analysis is a diagnostic tool that enables the clinician objectively to differentiate mild spastic diplegia from idiopathic toe-walking.
