Angelman syndrome (AS) is characterized by severe psychomotor retardation, speech impairment, happy disposition with bursts of laughter, ataxia, convulsions, and some distinct physical anomalies. Correct diagnosis of AS is important because of its clinical implications, and once the disease is confirmed, familial genetic counseling becomes crucial. We evaluated 22 patients with a putative diagnosis of AS by both clinical and molecular cytogenetic analysis. A deletion of the region 15q11-13 could be identified cytogenetically in 11 cases by high-resolution technique (group I). Four additional cases were confirmed by fluorescence in situ hybridization (FISH) study with D15S11, SNRPN, D15S10, and GABRB 3 [Prader-Willi syndrome (PWS)/AS region probes] (group II). The common deletion of GABRB 3 was documented in those AS cases (n = 15) by FISH. The other 7 cases exhibited no deletion over 15q11-13 at either the cytogenetic or molecular level (group III). We compared the following associated neurological disorders: convulsions and abnormal EEG, microcephaly, sleep and behavior problems, brain anomalies proved by image studies, sexual precocity with pineal tumor among the three groups, as well as other clinical conditions including congenital heart disease, obesity, scoliosis, and hypopigmentation. In the present study, the differences in neurological and facial characteristics were not distinct among these groups. However, the associated conditions were more frequently observed in the patients with deletion than in those without deletion. The EEG features of AS appear to be less sufficient in helping identify patients at an early age before the clinical features become obvious. Therefore, a region involved in the major As phenotypes may contain only one or more tightly contiguous genes around the GABRB 3 locus, which may explain the clinical heterogeneity in AS.

Osteopathia striata with cranial sclerosis (OS-CS) is a bone dysplasia characterized by hypertelorism, macrocephaly, frontal bossing, broad nasal bridge, palate anomalies, hearing deficits, and mental retardation. The radiographic findings include cranial sclerosis, linear striations in the long bones and iliac wings, small poorly aerated sinuses, scoliosis, and increased bone density. The sensory deficits are disabling, but the condition generally is not life threatening. We describe 4 brothers with the characteristics of OS-CS, 3 of whom have died from more serious complications of the disorder. The mother of these children, and her only daughter, have the mildest phenotype with the typical linear striations in the long bones and macrocephaly. OS-CS is thought to be autosomal dominant with complete penetrance and variable expressivity. Our observations could be consistent with X-linkage, since there is milder expression in the female relatives. In addition, we recognize absent fibulae, malrotation, and omphalocele as new manifestations as well as congenital heart disease.

The strong association between congenital heart disease and spinal deformity is well established, but data on the risks and outcome of spinal fusion surgery in patients with congenital heart disease are scarce. The purpose of this study was to identify predictors of perioperative risk and outcome in a large series of children and adolescents with congenital heart disease who underwent spinal fusion for scoliosis or kyphosis. In the authors' retrospective analysis of 74 consecutive patients with congenital heart disease undergoing spinal fusion, there were two deaths (2.7%) and 18 significant complications (24.3%) in the perioperative period. Preoperative cyanosis (arterial oxygen saturation < 90% at rest) with uncorrected or incompletely corrected congenital heart disease was associated with both deaths. Complications occurred in nine of 18 (50%) patients with cyanosis and in 11 of 56 (20%) patients without cyanosis. As judged by multivariate analysis the best predictors of perioperative outcome were the overall physical status of the patient as represented by the American Society of Anesthesiologists' preoperative score and a higher rate of intraoperative blood loss. Seventeen of 43 patients (40%) with an American Society of Anesthesiologists score of 3 or higher experienced complications including two perioperative deaths. Successful spinal fusion and correction were achieved in 97% of patients. Children and adolescents with congenital heart disease can undergo elective spinal fusion with risks that relate to overall cardiac status. Careful assessment of preoperative status by pediatric cardiologists and cardiac anesthesiologists familiar with surgical treatment of patients with congenital heart disease will assist the orthopaedic surgeon in providing the most realistic estimate of risk.

Advances in the treatment of congenital heart disease have led to a new group of adolescents or adults patients with cardiac anomalies. The anaesthetic management of these patients can be challenging especially when they are scheduled for major noncardiac surgery inducing haemodynamic instability. We report the case of a 14-year-old boy scheduled for posterior spinal fusion for idiopathic scoliosis who underwent a Fontan operation in infancy for pulmonary atresia with right ventricle hypoplasia. The preoperative investigations and the anaesthetic management are described.

Cardiac transplant surgery is being performed with increasing frequency as a treatment for end-stage heart disease. In addition to the well-known post-surgical problems of rejection and infection, these patients may present at a future date with other medical problems which require surgical treatment, including orthopaedic pathology. Severe idiopathic scoliosis has been described in association with congenital heart disease, and its surgical treatment poses considerable risks because of heart disease. Spinal fusion in heart transplant recipients involves similar risks due to the particular physiology and pharmacological reactions of the denervated heart. Several cases of cholecystectomy performed in heart transplant recipients have been described, but to our knowledge no orthopaedic procedures have been reported in such patients. We report on a 15-year-old patient who underwent successful corrective surgery for idiopathic scoliosis 14 months after heart transplant.

The association is well established between congenital heart disease and spinal deformities such as scoliosis or kyphosis, but data are not available for risks and the outcome of heart surgery in patients with spinal deformities. We report a case of successful orthotopic heart lung transplantation in a patient with complex congenital heart disease and severe chest deformity who had undergone previous spinal fusion surgery for progressive right convex thoracic kyphoscoliosis.

The Marshall-Smith syndrome (MSS) is rare congenital disorder, characterized by a triad of orofacial dysmorphism, failure to thrive, and accelerated osseous maturation. An 8-year-old boy with MSS associated with congenital glaucoma, corneal erosion, laryngomalacia, glossoptosis, choanal stenoses, bilateral peripheral hearing defect, ventriculomegaly, congenital heart disease (atrial septal defect), chronic pulmonary disease, and scoliosis was reported. A tracheostomy with endotracheal tube insertion was performed for his difficult airway. He has longer survival time than those MSS patients hitherto reported. High-resolution chromosome banding and extensive metabolic investigation did not detect any abnormality, except for low blood levels of zinc and thyroxine. Besides, brain atrophy with hypoplastic cerebellum and brainstem, and bilateral hydronephrosis with hydroureter were detected by image studies.

The clinical presentation of right ventricular (RV) dysfunction due to congenital heart disease (CHD) is similar to that of cor pulmonale. RV volume and pressure loads, and primary RV myocardial dysfunction are mechanisms by which CHD affects right heart function. RV volume load may arise from pre-tricuspid left to right shunts (e.g., atrial septal defect) or regurgitant lesions in the right heart (e.g., Ebstein's anomaly of the tricuspid valve and pulmonary insufficiency after repair of tetralogy of Fallot). RV pressure load may be caused by anatomic obstruction to RV outflow and by pulmonary arteriolar hypertension. The latter can result from Eisenmenger syndrome secondary to congenital and postoperative left to right shunts or from defects that cause pulmonary venous hypertension (e.g., pulmonary vein stenosis, cor triatriatum, or mitral stenosis). The RV myocardium may be affected by a primary cardiomyopathy or by congenital abnormalities of the coronary vessels. Finally, CHD may be associated with airway obstruction, scoliosis, or pulmonary emboli, which, in turn, may lead to the development of cor pulmonale. Congenital heart disease, therefore, must be included in the differential diagnosis of patients who present with right ventricular dysfunction.

Children with early onset scoliosis typically present before age 5 years. Radiographic criteria help to distinguish progressive cases from those that will spontaneously resolve. Severe cardiopulmonary problems may occur in untreated progressive cases. A comprehensive evaluation should be performed to identify commonly associated conditions, such as plagiocephaly, congenital heart disease, inguinal hernia, and hip dysplasia. For curves >20 degrees , magnetic resonance imaging of the neural axis is indicated to rule out occult central nervous system lesions. Surgical management should be considered when nonsurgical measures, including bracing and casting, fail to arrest progression. Surgical methods continue to evolve and are primarily directed at obtaining and maintaining curve correction while simultaneously preserving spinal and trunk growth.

We report the development and spontaneous resolution of annular erythematous skin lesions consistent with sarcoid dermatitis in a child with DiGeorge syndrome (DGS) carrying the 22q11.2 microdeletion. The skin lesion developed after she was treated with isoniazid (INH) following exposure to active tuberculosis (TB). After resolution of the skin lesions, this child developed sterile hyperplastic osteomyelitis consistent with SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) osteomyelitis in her right mandible triggered by an odontogenic infection. This child had congenital heart disease, dysmorphic facies, recurrent sinopulmonary infection, gastroesophageal reflux disease, scoliosis, reactive periostitis, and developmental delay. She had a low CD4 and CD8 T cell count with a normal 4/8 ratio, but normal cell proliferation and T cell cytokine production in response to mitogens. When she was presented with sterile osteomyelitis of right mandible, she revealed polyclonal hypergammaglobulinemia with elevated erythrocyte sedimentation rate (ESR)/angiotensin converting enzyme (ACE) levels, but negative CRP. Autoimmune and sarcoidosis workup was negative. Inflammatory parameters gradually normalized following resolution of odontogenic infection and with the use of non-steroidal anti-inflammatory drugs (NSAIDs). The broad clinical spectrum of DGS is further expanded with the development of autoimmune and inflammatory complications later in life. This case suggests that patients with the DGS can present with unusual sterile inflammatory lesions triggered by environmental factors, further broadening the clinical spectrum of this syndrome.
