Wolf-Hirschhorn syndrome is a multiple malformation syndrome associated with mental and developmental retardation, resulting from a deletion at the short arm of chromosome 4(4p16.3). We report a 11-year-old girl with Wolf-Hirschhorn syndrome, who was presented with severe growth and mental retardation along with characteristic features-frontal bossing, hypertelorism, downslanting of the palpebral fissures and fishlike lips. The diagnosis was confirmed by... |
The Prader-Willi syndrome(PWS) and Angelman syndrome(AS) are clinically distinct syndromes with a shared cytogenetic deletion of chromosome 15q11q13 in most patients. Currently the diagnosis of PWS/AS is clinically suspected and can be confirmed by genetic laboratory tests. However, their diagnosis remains difficult in neonates and early infants because many features of the syndromes change with age and the typical features... |
Purpose : To detect microdeletion of 15q11-13 region, high resolution cytogenetic analysis or FISH with probe at Prader-Willi syndrome region can be used. We tried to evaluate whether FISH with SNRPN is a more effective method than G-banding microscope in the diagnosis of Prader-Willi syndrome. Methods : Peripheral blood sampling was done on five patients who we suspected of Prader-Willi syndrome... |
We experienced two cases of congenital localized skin defect and neonatal onset of relapsing subepidermal blisters associated with minor trauma in a female newborn infant and her mother. The mother of index case showed toe nail dystrophy at delivery of her daughter, but the index case did not reveal nail dystrophy until 14 months of age. The congenital skin defects... |
Megacystis Microcolon Intestinal Hypoperistalsis(MMIH) Syndrome is a rare cause of functional neonatal bowel obstruction, characterized by hypoperistalsis, narrow distal ileum and colon, and bladder distension. We report a case of MMIH syndrome and review the literature. The patient was born after 34 weeks of gestation with marked abdominal distension. Her birth weight was 2,830g with 276ml of urine drained by... |
Since Pallister first described 12p tetrasomy syndrome in 1977, approximately 50 patients have been described. Chromosomal study of lymphocyte is normal in most cases, but fibroblasts usually reveal 12p tetrasomy in chromosomal study. We report on a 17-month-old male infant with Pallister-Killian syndrome. He was admitted in our hospital for investigation of developmental delay and myoclonic seizure. He was diagnosed... |
Greig cephalopolysyndactyly syndrome(GCPS) is a disorder characterized by postaxial polydactyly of the hand, broad or occasionally bifid thumbs, preaxial polydactyly of the feet, broad halluces, syndactyly of the fingers or toes, macrocephaly, frontal bossing, hypertelorism and a broad nasal bridge. Intelligence is usually normal, although borderline IQ has been reported. Advanced bone age, mild hydrocephalus, craniosynostosis and agenesis of the corpus callosum are occasionally associated... |
OTC deficiency is an X-linked disorder in which the synthesis of urea is impaired. OTC catalyzes the synthesis of citrulline from carbamyl phosphate and ornithine. Complete or partial deficiencies of this enzyme may lead to Reye syndrome like picture such as encephalopathy, hepatic dysfunction, hyperammonemia, etc. We recently had a case that was presented as recurrent Reye syndrome, and was... |
Purpose : Antenatal dexamethasone administration is associated with a significant lowering respiratory distress syndrome(RDS) incidence, but can increase neonatal infection. Ambroxol has been accepted as an alternative treatment to dexamethasone and is of at least equal efficacy but without adverse reaction. The aim of this study was to evaluate the effectiveness of ambroxol versus dexamethasone in RDS incidence and neonatal... |
Purpose : To examine the clinical effects of two bronchodilator agents, salbutamol and ipratropium bromide, administered by metered-dose inhaler(MDIS) to preterm infants with respiratory distress syndrome(RDS) during mechanical ventilation. Methods : This study included 8 ventilated preterm infants with RDS, at a postnatal age of 1 week. The effects of single doses of salbutamol(2puffs, 200mcg) and ipratropium bromide(2 puffs, 36mcg) and... |
Toxic epidermal necrolysis(TEN) is a bullous disorder affecting mainly basal layers of epidermis by hypersensitive reaction. It is rarely reported in infants under six months of age. It can be developed by drug, infection, and vaccination, which makes it difficult to differentiate from staphylococcal scalded skin syndrome(SSSS) especially in early infancy. We report a case of TEN in a 6-week-old... |
Parry-Romberg syndrome(Progressive hemifacial atrophy), described in the last century by Parry(1825) and Romberg(1846), is a very rare disorder characterized by a slowly progressive and self-limited unilateral(rarely bilateral) atrophy of the faces affecting variably the skin, subcutaneous fat tissues, musculature, connective tissue, cartilage and bones. And this disorder is usually accompanied by contralateral Jacksonian epilepsy, trigerminal neuralgia, and changes in the... |
Marfan syndrome is infrequently diagnosed early in infancy. The morphologic characteristics and prognosis in infantile Marfan syndrome may be quite different from those in older patients. Characteristic cardiac findings in early life include mitral valve prolapse, valvular regurgitation, and aortic root dilation. Morbidity and mortality may be high for infants diagnosed with Marfan syndrome. Cardiac surgery for cardiovascular complication in... |
Purpose : Menstrual disorders are very common problems in adolescence. Most of them are minor, including mild dysmenorrhea, premenstrual syndrome(PMS) and minor variations in cycle, length, or amount of flow.
