Background: The worldwide incidence of congenital anomalies (CAs) is estimated at 3–7%, but actual numbers vary widely among countries. Birth defects are the most common causes of infantile mortality, accounting for ~25% of all neonatal deaths. Aims: To determine the prevalence of congenital anomalies in neonates in Fayoum Governorate; to classify malformations; and to clarify the association between congenital anomalies and possible risk factors. Methods: A cross-sectional study was conducted on 1000 infants in the neonatal intensive care unit and outpatient clinics of Fayoum University Hospital and Fayoum General Hospital during August 2017 to April 2018. Detailed history, clinical examination and relevant investigations were performed. Results: The prevalence of CAs was 7.4%. Major malformations accounted for 78.4% and minor malformations 21.6%. The most common CAs involved the cardiovascular system (32.4%), followed by musculoskeletal anomalies (18.9%), chromosomal anomalies (10.8%), anomalies of the central nervous system (9.5%), gastrointestinal tract (6.8%), genital system (5.4%), eyes, head and neck (5.4%), respiratory system (4.1%), multisystems (2 or more) (4.1%), and renal and urinary systems (2.7%). 82.4% of cases were from rural areas, 62.1% were male, 36.5% were female and 1.4% were ambiguous. 85.1% of neonates with malformations were full term. Conclusion: Cardiovascular, musculoskeletal and chromosomal anomalies were the most common CAs in our study. Positive consanguinity, poor attendance at antenatal clinics, rural residence and multiparty were the most common risk factors associated with CAs.

Background Wolf–Hirschhorn syndrome (WHS) (OMIM 194190) is a multiple congenital anomalies/intellectual disability syndrome. It is caused by partial loss of genetic material from the distal portion of the short arm of chromosome. Methods We studied the phenotype–genotype correlation. Results We present the clinical manifestations and cytogenetic results of 10 unrelated Egyptian patients with 4p deletions. Karyotyping, FISH and MLPA was performed for screening for microdeletion syndromes. Array CGH was done for two patients. All patients exhibited the cardinal clinical manifestation of WHS. FISH proved deletion of the specific WHS locus in all patients. MLPA detected microdeletion of the specific locus in two patients with normal karyotypes, while array CGH, performed for two patients, has delineated the extent of the deleted segments and the involved genes. LETM1, the main candidate gene for the seizure phenotype, was found deleted in the two patients tested by array CGH; nevertheless, one of them did not manifest seizures. The study emphasized the previous. Conclusion WHS is a contiguous gene syndrome resulting from hemizygosity of the terminal 2 Mb of 4p16.3 region. The Branchial fistula, detected in one of our patients is a new finding that, to our knowledge, was not reported.

Opsoclonous myoclonous ataxia syndrome (OMAS) is a rare primarily immune-mediated disease in children. The current study aim was to find out the patterns and outcome of OMAS associated with neuroblastoma (NBL) among Children’s Cancer Hospital—Egypt patients. Data was reviewed for 15 eligible patients enrolled between 2007 and 2016. OMAS treatment included prednisolone and cyclophosphamide with/without intravenous immunoglobulin; NBL treatment was given according to risk-corresponding protocol. Patients’ age ranged from 0.75 to 12 years at presentation with male/female: 1.1/1. Concurrent diagnosis of OMAS and NBL occurred in 6 patients (40%). OMAS preceded NBL within 0.25 to 2 years in 33%, while NBL preceded OMAS within 0.5 to 1.5 years in 27%. Full OMAS picture was present in 10/15 patients, while 20% presented with truncal ataxia and myoclonus, 1 with truncal ataxia and opsoclonus, and 1 had opsoclonus and myoclonus. Median time till improvement of manifestations was 5 months. The 5-year OMAS progression-free survival was 33.3%, where 10 patients needed second-line therapy due to relapse/progression of OMAS. The median time to progression was 28 months measured from OMAS diagnosis. All patients remained alive with NBL 5-year overall survival of 100% and event-free survival of 85.7% for. However, 73% of the patients showed late sequelae ranging from ocular to cognitive, behavioral and motor disorders; rarely seizures and hemolytic anemia.

Background: Hemihypertrophy is a condition in which one side or part of the body is larger than the other. The asymmetry can range from mild to severe. It is important to establish a diagnosis because hemihypertrophy is associated with an increased risk for embryonal tumors, mainly Wilms tumor and hepatoblastoma.

Introduction: Congenital heart disease (CHD) is the leading cause of mortality and morbidity during the first two years of the Down Syndrome (DS) patient's life. Studies showed that 40-63.5% of DS patients had CHD. The defects can involve the heart walls, valves, veins, and arteries. They might develop congestive heart failure, pulmonary vascular disease, pneumonia, or failure to thrive. Aim of the study:The current study aimed to define the prevalence and patterns of congenital heart disease (CHD) among children with Down syndrome (DS) in Fayoum Governorate. Subjects and Methods:The study recruited 150 pediatric DS patients from the cardiology and genetic
