The occurrence of signs and symptoms in the Rett syndrome (RS) was analyzed in a series of females born 1945-87 (median age 17 1/2 years) and fulfilling the diagnostic criteria for classic RS. For general information, data from 91 girls and women were used (group A), while the more detailed analyses were based on three age related subgroups: the youngest 20, born 1980-87 (group B); the 34 girls born 1970-79 (group C); and the oldest 37, born 1945-69 (group D). Data from group A indicated a developmental stagnation (stage I) at median age 11 (5-24) months and loss of ability to use acquired skills (stage II) at 19 (12-36) months. Group B displayed subtle prodromes in the first months of life, and later in infancy gross motor delay with insufficient equilibrium control. Development invariably came to a definite break at a crucial stage of maturation and was followed by a remarkable "awakening" and return of interest to act and interact (stage III). Loss of skills belonged to the triad contact/communication, hand use/skill, and babble/words. By age 2 1/2 years, apraxia and involuntary and stereotyped movements, were found in all. Seizures, hyperventilation and spells of screams and laughter were more frequent in group C (94%, 65% and 71%, respectively), and breathholding, bloating and drooling in group D (73%, 43% and 81%, respectively). Plantar flexion and abiotrophy of feet, as well as peroneal weakness and scoliosis, increased with age and was found in 89%, 86%, and 89%, respectively. The sequence of events described, emerged as subtle insufficiency and more or less abruptly turned into loss. Conversely to known progressive encephalopathies, the deterioration was followed by excess of activity, only years later to turn into restriction.

We report on 4 generations in a family with 3 living males, 3 males who died in infancy, and 3 females with neurologic impairment and agenesis of the corpus callosum (ACC). Manifestations in the surviving males include severe acquired micrencephaly, mental retardation, limb contractures, scoliosis, tapered digits with hyperconvex nails, a characteristic face with large eyes, prominent supraorbital ridges, synophris, optic atrophy, broad alveolar ridges and seizures. Urologic anomalies include renal dysplasia, cryptorchidism, and hypospadias. Two affected females were less severely impaired and continued to be socially responsive as adults, but had spastic quadriplegia and seizures. One obligate heterozygote was retarded with emotional problems while another obligate carrier female and her daughter were clinically normal. Pedigree analysis suggested X-linked inheritance with variable expression in females. These findings are inconsistent with the well-described X-linked conditions with ACC including FG syndrome and Aicairdi syndrome. ACC has not been described in Coffin-Lowry syndrome, a condition with similar clinical findings, which also demonstrates marked variability of expression in carrier females. In order to assist in carrier determination, brain imaging studies and DNA linkage analysis of the affected relatives was performed. We found a spectrum of agenesis of the corpus callosum with the most severe manifestations in the most severely affected males. DNA analysis using a series of X-linked probes suggests linkage with a LOD score of 1.26 at theta = 0 to a region between p 11.3 and p 21.3.

We described a 5-month-old girl with Aicardi syndrome accompanied by auditory disturbance and multiple brain tumors. She was admitted to our hospital because she suffered from intractable flexor spasms. Physical examination revealed craniofacial asymmetry, left auricular deformity, scoliosis, and remarkable hypotonia with psychomotor retardation. Abnormal ophthalmological findings included chorioretinopathy with pale and round-shaped peripapillary lacunae, and there was modified hypsarrhythmia in her EEG. MRI revealed multiple brain tumors in the 3rd and the lateral ventricles which are considered to be choroid plexus papilloma with agenesis of the corpus callosum. ACTH therapy was administered because of the intractable seizures. After ACTH therapy, the thresholds of waves I and V were much improved. The interpeak latency of waves I-V of the left ear and the peak latency of wave I of the right ear had been lengthened. Acoustic reflex with contralateral stimulation showed no response in the left ear. These findings indicate that the auditory system is also involved in the Aicardi syndrome and that ACTH is effective for its dysfunction.

We report the clinical, laboratory, and magnetic resonance imaging results of 4 adult patients (ages 25, 26, 29, and 35 years) with stage IV Rett syndrome. The patients were diagnosed at an institution for the handicapped. Two of them had been previously diagnosed as having cerebral palsy. All were microcephalic and had seizures, although the frequency of seizures decreased with advancing age. Three patients had scoliosis. Magnetic resonance imaging demonstrated marked craniofacial disproportion in 2 patients, bilateral atrophy of the frontotemporal lobes in 3, and cerebellar atrophy in 1. The cerebrospinal fluid concentrations of biopterin and homovanillic acid did not differ significantly in these Rett syndrome patients from age-matched controls.

Diagnostic criteria for Rett syndrome (RS) were developed by representatives of the International Rett Syndrome Association and the Centers for Disease Control for use in future clinical and epidemiological studies. Necessary criteria are: normal prenatal and perinatal period; normal psychomotor development through the first 6 months of life; normal head circumference at birth, with subsequent deceleration of head growth; loss of purposeful hand skills; severely impaired expressive and receptive language; apparent severe mental retardation; and gait apraxia and truncal apraxia/ataxia. Supportive criteria include breathing dysfunction, seizures, spasticity, scoliosis, and growth retardation. The diagnosis of RS is considered tentative until 2 to 5 years of age. The differential diagnosis includes other disorders associated with mental retardation, cerebral palsy, and seizure disorders. These diagnostic criteria for RS should foster reliable communication among investigators and enhance the epidemiological and clinical research of this important disorder.

Thirty-four nonambulatory patients with progressive neuromuscular spinal deformity were surgically managed using a 1/4" U-shaped double rod construct with segmental instrumentation from T2 to the pelvis accompanied by posterior spinal fusion. Diagnoses included 17 patients with cerebral palsy, six with spinal bifida, and 11 with other diseases (spinal muscular atrophy, Friedreich's ataxia, polyneuropathy, nemaline myopathy, and polio). Twenty-three patients had single uncompensated thoracolumbar curves, and 11 had a double curve pattern. The mean preoperative major curve was 66 degrees (range, 22-132 degrees), the secondary curve 58 degrees (range, 23-84 degrees). No postoperative spinal support was used. Mean curve correction was 36 degrees or 54.6%. There were four major complications, including two implant failures requiring revision and two patients sustaining excessive intraoperative blood loss necessitating completion of the procedure in a second stage. There were two neurologic complications including one case of postoperative seizures and an L4 monoradicular neuropathy in a spina bifida patient. Four patients had temporary postoperative ileus, one gastroesophageal reflex, and four had urinary tract infections. There were no significant postoperative pulmonary complications. Excluding the patients with rod failure, mean loss of correction at mean follow-up of 21.3 months was 6.5%. The stability and curve correction obtained using this system supports its continued use in patients with progressive neuromuscular scoliosis.

Nineteen children with hypomelanosis of Ito are described. Fourteen were developmentally delayed and nine had a history of seizures. Hemihypertrophy was present in four patients, syndactyly in three, and scoliosis in one. Twelve of the children had abnormal electroencephalograms and nine had abnormal brain scans, four with appearances suggestive of abnormal neuronal migration. There is very little evidence, either from the literature or from our patients, that the disease is inherited. The pattern of the cutaneous lesions suggests that the condition may result from the presence of two different cell populations as a result of mosaicism.

Eighteen girls with Aicardi syndrome were identified through a survey of neurologists, geneticists, and ophthalmologists. All had infantile seizures, developmental delay, agenesis of the corpus callosum (complete: 72%, partial: 28%), and characteristic chorioretinal lacunar lesions. Costovertebral defects including hemivertebrae, scoliosis, and absent or malformed ribs were present in 39%, cortical heterotopias were present in 50%, and microphthalmia was identified in a third. Cytogenetic investigation was carried out in all families. An unbalanced X;3 translocation, 46,X,der(X)t(X;3)(p22.3;p23)mat, was discovered in a girl with chorioretinal lacunar lesions characteristic of Aicardi syndrome, developmental delay, and infantile seizures. However, this child had a normal appearing corpus callosum on CT and magnetic resonance imaging scans and therefore did not meet the criteria for inclusion in the study. Chromosomes of all other patients and parents were normal. Findings at birth, age of seizure onset, treatment, and prognosis are discussed. The pedigree data from these 18 families demonstrated an unaffected male:female sib ratio of 1:1.7 and a 14% spontaneous abortion rate. The findings of this study support the contention that Aicardi syndrome is an X-linked dominant disorder with early embryonic lethality in hemizygous males and that all cases represent new mutations.

In a 23 year old female patient, hospitalized at the internal ward for precollapse condition in tachyarrhythmia seizure with signs of the Turner's syndrome and a corresponding chromosomal finding, a radiographic examination of thorax revealed, beside a spine deformity with a marked scoliosis, a spindle-like aneurysmatic dilatation of aortic arc. The duplication of its contour indicated suspected beginning dissection. The further course did not confirm it, though. The possibility of excluding atherosclerotic and luetic etiology of the aneurysm makes it possible to consider the Erdheim's cystic medionecrosis of aorta, which accompanies more frequently the Marfan's syndrome, whereas in the Turner's syndrome it has been reported exceptionally.

A case of hemihypertrophy associated with multiple anomalies of the skin, bone and visceral organs is presented. A 31-year-old female was admitted for evaluation of her skin conditions. Her family history is noncontributory, while her past history discloses operations for syndactyly of the right foot, tonsillar hypertrophy, anal prolapse and ovarial cyst. Erythemas of the face and the left upper extremity were noticed during the neonatal period and hypertrophy of the right side of the body started at age 2 months. On admission, hemihypertrophy was observed in the face, trunk and extremities. Multiple faint nevi flammei were seen on the right half of the face and on the left side of the trunk and extremities. Telangiectasis and nevus anemicus were seen in the upper chest. The left upper extremity showed diffuse brown patches that was histologically basal pigmentation with some giant melanosomes. Visceral anomalies consisted of fibromatous tumors of the tip of the tongue and mitral prolapse. Angiography and computed tomography revealed a possible arteriovenous malformation of the right occipital region, small hemangiomas around the patella, dilation of the lateral ventricle, and calcification of the choroid plexus. Tortuous superficial veins were noted in the right leg. She had no seizure, but her IQ was 68. The bone disorders consisted of scoliosis, short forth metacarpus, hypoplastic mandible and peroneal exostosis. Examination revealed a slight diminution of urinary corticosteroid, but no other endocrinological disorders were found. The hemihypertrophy in this case is at least partially due to an arteriovenous shunt, suggested by elevated oxygen saturation of the blood obtained from the internal saphenous vein.(ABSTRACT TRUNCATED AT 250 WORDS)
