RESUMEN
We report on a patient carrying a 17q21.31 microdeletion and exhibiting many common syndrome features, together with other clinical signs which have rarely or never been described to date. The detected 695-kb 17q21.31 deletion is larger than in most previously reported cases but is still probably the result of recombination between flanking low-copy repeats. Due to the complexity of the patient's clinical condition, together with the presence of 3 previously unreported symptoms, namely chronic anemia, cervical vertebrae arthrosis and vertebrae fusion, this case is an important addition to the existing knowledge about the 17q21.31 microdeletion syndrome.
RESUMEN
We report on clinical evaluations of Brazilian patients with misoprostol-induced arthrogryposis. All 15 patients had growth retardation, underdeveloped bones, short feet with equinovarus, rigidity of several joints with skin dimples and webs, decreased movement of legs stemming from neurologic impairment, bilateral symmetrical hypoplasia or atrophy of limb muscles, and absent tendon reflexes. Of the 15 patients, five had upper limb deformities in addition to lower limb involvement, and one had spinal cord disruption leading secondarily to segmental sensory loss and neurogenic bladder and bowel. Electroneuromyography of five patients indicated that the abnormalities were of neurogenic origin and suggestive of anterior horn cell defects. All of their mothers took 400-4,800 mcg of misoprostol orally or vaginally at 8 to 12 weeks of pregnancy. Our observations support a previously stated caution with regard to the embryotoxicity of misoprostol.
