During the planning stages of deinstitutionalization, the importance of nursing services must be recognized and given priority consideration in the community placement of persons with serious developmental disabilities. The objective of this study was to survey the medical and nursing profile of a group of nonambulatory, institutionalized individuals with profound mental retardation in anticipation of their nursing and medical needs in the community. Data were collected from the Individual Habilitation Plans of 55 individuals who had resided in a residential facility for individuals with mental retardation and were scheduled for community placement Serious medical problems in decreasing frequency were constipation (96%), seizure disorder (70%), poor dental hygiene (67%), cerebral palsy (62%), scoliosis (61%), contractions (41%), aspiration (44%), skin lesions (40%), and dysphagia (22%). Considering the complexity of health issues encountered in this population, adequate nursing and medical planning are critical to the wellness and successful community placement of a population with special needs.

Mutations in the MECP2 (methyl-CpG-binding protein 2) gene are known to cause Rett syndrome, a well-known and clinically defined neurodevelopmental disorder. Rett syndrome occurs almost exclusively in females and for a long time was thought to be an X-linked dominant condition lethal in hemizygous males. Since the discovery of the MECP2 gene as the cause of Rett syndrome in 1999, MECP2 mutations have, however, also been reported in males. These males phenotypically have classical Rett syndrome when the mutation arises as somatic mosaicism or when they have an extra X chromosome. In all other cases, males with MECP2 mutations show diverse phenotypes different from classical Rett syndrome. The spectrum ranges from severe congenital encephalopathy, mental retardation with various neurological symptoms, occasionally in association with psychiatric illness, to mild mental retardation only. We present a 21-year-old male with severe mental retardation, spastic tetraplegia, dystonia, apraxia and neurogenic scoliosis. A history of early hypotonia evolving into severe spasticity, slowing of head growth, breathing irregularities and good visual interactive behaviour were highly suggestive of Rett syndrome. He has a de novo missense mutation in exon 3 of the MECP2 gene (P225L). The clinical spectrum and molecular findings in males with MECP2 mutations are reviewed.

Dubowitz syndrome is a disorder involving craniofacial abnormalities, growth retardation and mental retardation. Approximately 142 cases have been reported, with various associated other anomalies. These include cardiovascular, urogenital and endocrine abnormalities, as well as a predisposition to infections and hematological malignancies. Scoliosis has been described in association with this syndrome, as have isolated vertebral abnormalities. There has, however, been no description of craniocervical abnormalities. We describe three Dubowitz patients with significant craniocervical abnormalities.

The term "cutis tricolor" describes the combination of congenital hyper- and hypo-pigmented lesions, in close proximity to each other with a background of normal skin. Cutis tricolor represents twin spotting and has been reported as an isolated skin disorder or as part of a neurocutaneous malformation syndrome. We report on an 11-year-old girl with diffuse pigmentary changes of the cutis tricolor type, facial anomalies, mental retardation, epileptic seizures, EEG anomalies, small skull, progressive double-curved thoracolumbar/lumbar scoliosis with vertebral scalloping and dysplastic vertebral pedicles and ribs, and tibial bowing. These abnormalities are similar to those observed in cases reported by Happle et al. [1997: J Med Genet 34:676-678] and Ruggieri [2000: Eur J Pediatr 159:745-749]. Additionally, our patient had altered behavior and hypoplasia of the corpus callosum. This constellation of abnormalities represents a newly recognized neurocutaneous malformation syndrome. The phenotype could be explained by somatic mutation. Loss of heterozygosity at an early developmental stage would give rise to one single mosaic skin disorder (e.g., generalized skin manifestations of the cutis tricolor type in association to extracutaneous anomalies). Postzygotic recombination occurring later during embryogenesis would give rise to solitary lesions confined to the skin.

We describe two brothers with a unique pattern of malformations that includes coloboma (iris, optic nerve), high forehead, severe retrognathia, mental retardation, and agenesis of the corpus callosum (ACC). Both boys have low-set cupped ears with sensorineural hearing loss, normal phallus, pectus excavatum, scoliosis, and short stature. One brother had choanal atresia and cardiac defects consisting of ventricular septal defect (VSD) and patent ductus arteriosus (PDA) which resolved spontaneously. Differential diagnosis between a number of clinical entities was considered, however, because ACC and the distinctive facial features were reminiscent of FG syndrome, DNA was analyzed for markers linked to the FGS1 locus at Xq13-q21. Notably, the brothers were concordant for markers spanning this presumed FG region, and in both we have identified adjacent alterations (-57delT and T-55A) in the Alpha 4 gene located within this interval. Alpha 4 is a regulatory subunit of the major cellular phosphatase, PP2A, that has recently been shown to interact with MID1, the product of the gene mutated in X-linked Opitz GBBB syndrome. The double nucleotide change identified in this family was not observed in 410 control chromosomes, suggesting that it may be a pathogenetic change. Altered expression of Alpha 4, through either a change in translational efficiency, mRNA stability or splicing, could explain the clinical phenotype in these boys and the phenotypic overlap with Opitz GBBB syndrome.

Desbuquois dysplasia is a rare chondrodysplasia characterized by short stature, joint laxity, and specific radiographic findings. We report the natural history of four patients (three boys and one girl) with Desbuquois dysplasia ages 16-22 years. The mean height in adulthood was 114 cm (-8.5 SD) with progressive deceleration of the growth curve from birth (-4 SD) to adulthood. Obesity was noted consistently and facial abnormalities were still present but less obvious than in childhood. Three of four patients had mental retardation of varying degree. Hyperlaxity was persistent but limited motion of various joints was also noted. Orthopedic complications included coxa vara or valga (3/4), scoliosis (3/4), marked lordosis (3/4), and ambulatory difficulties (3/4). Surgical treatment was necessary for all four patients, involving large joints, spine and hands. Other complications included acute open-angle glaucoma secondary to a congenital malformation of the angle in one case. In addition to consistent radiological findings, elevated greater trochanter, generalized osteoporosis especially of the spine, scoliosis and/or lordosis, wide metaphyses, flat epiphyses, and coxa vara or valga were part of the natural history of the disorder. Our study emphasizes the care of older patients with Desbuquois dysplasia.

Brachmann-de Lange syndrome (BDLS) is a disorder of unknown cause that is recognized on the basis of characteristic facies in association with growth retardation, mental retardation and, in many cases, upper limb anomalies. Because of its association with skeletal anomalies, patients with the syndrome are often referred to the paediatric orthopaedic surgeon. Thirty-four patients with Brachmann-de Lange syndrome were evaluated for the prevalence and pattern of musculoskeletal involvement. The average age of the patients was 10.2 years (range, 1 month to 44 years). Both sexes were affected equally. The common orthopaedic manifestation affected the hand (100%), elbow (47%), and the heel cord (26%). Severe bony anomalies included complete absence of the hand in one case, and ulna hemimelia in two cases. In two patients bilateral Legg-Perthes-like changes were noted. Scoliosis presented in four cases, all before the age of 10 years. Surgery was performed in two patients with severe bilateral equinovarus feet. Despite the constellation of musculoskeletal findings, most of the patients did not have surgical intervention for their deformities.

Prader-Willi syndrome (PWS) is characterized by hypotonia, obesity, hypogonadism, small hands and feet, and mental deficiency. Obesity and hypogonadism are also frequently associated with slipped capital femoral epiphysis (SCFE), suggesting that children with PWS might be at increased risk of developing SCFE. Members of the Prader-Willi Syndrome Association (U.S.A.) were surveyed regarding the history of orthopaedic problems in general and of SCFE in particular. A total of 565 (63%) responses were received. The prevalence of orthopaedic conditions included 47% with flat feet, 41% with scoliosis, 19% with knock knees, 10% with hip dysplasia, 9% with osteoporosis, 7% with patellofemoral instability, 3% with bowlegs, 2% each with clubfeet, nursemaid's elbow, or leg-length inequality, and one patient (0.2%) with SCFE. The results of the survey indicate that SCFE is uncommon in patients with PWS, but the prevalence of hip dysplasia is increased approximately 10-fold compared with the general population.

To date, more than seven families have been reported who carry a mutation in the X-linked creatine-transporter (CrT) gene. The resulting lack of creatine in the brain is associated with mental retardation, severe expressive language disorder, mild epilepsy, and a complete absence of Cr in the brain (measured using MRS). Conversely, these patients had no observable cardiac or musculo-skeletal deficits. In this case study, a 22-year-old patient underwent surgical repair for scoliosis. Proton MRS of this patient's brain demonstrated the near-absence of creatine and phosphocreatine within the cerebral white and deep gray matter structures. Cerebral atrophy was noted with serial MRI examinations. Subsequent genetic and metabolic analysis showed some biochemical anomalies consistent with a CrT deficiency. The mutation in this patient was identified as a deletion at phenylalanine 107 (delF107). Control muscle biopsies were obtained from archived samples, which had been taken with informed consent during routine muscle biopsies for diagnostic purposes. We determined that the total Cr concentration in the skeletal muscle biopsy was 39.3 +/- 2.94 mmol/kg wet wt., which is not significantly different from non-CrT controls, n = 3 (43.3 +/- 3.57 mmol/kg wet wt.). We conclude that the brain appears to lack the ability to transport creatine when there is a mutation in the CrT gene. However, the muscle utilizes another mechanism for maintaining normal creatine levels. Identifying this alternative creatine-transport mechanism may be useful in treating the neurologic and cognitive impairments of patients with creatine-transporter deficiency.
