We encountered seven children with symptomatic congenital cytomegalovirus (CMV) infection from 1988 to 1995, of whom two (28.6%) developed typical autistic disorder. Case 1: A boy born at 38 weeks' gestation with a birth weight of 3164 g showed generalized petechiae, hepatosplenomegaly, and positive serum CMV-specific IgM antibodies. He was profoundly deaf, mentally retarded, and exhibited a lack of eye contact, stereotyped repetitive play, and hyperactivity. Case 2: A boy delivered at 39 weeks gestation with a birthweight of 2912 g showed non-progressive dilatation of the lateral ventricles observed postnatally. CMV-specific IgM antibodies were positive and CMV-DNA in the urine was confirmed by PCR. The boy was mentally retarded but not deaf. He showed no interest in people and delayed speech development. Subependymal cysts were detected by cranial ultrasound after birth in both patients. This is the first report describing subependymal cysts and the later development of AD. Cranial magnetic resonance imaging revealed an abnormal intensity area in the periventricular white matter suggestive of disturbed myelination; however, no migration disorders were found in our patients. These findings suggest that the timing of injury to the developing brain by CMV may be in the third trimester in some patients with autistic disorder.

Objectives Sanfilippo syndrome (Mucopolysaccharidosis III, MPS III) is a rare autosomal recessive hereditary disease, which is caused by lysosomal enzyme deficiency. This study was operated to investigate clinical and molecular characteristics of patients with MPS III, which will improve the diagnosis and treatment of MPS III. Method Thirty four patients with MPS III were assessed using clinical evaluation, questionnaire, and scoring system. Results Among the 34 patients, 14 had MPS IIIA, 19 had MPS III B, and one had MPS III C. Speech delay (100%) and intellectual disability (100%) were the most prevalent clinical manifestations in this cohort, followed by hyperactivity (94.12%), hirsutism (91.18%), enlarged head circumference (73.52%), repeated diarrhea (67.64%), sparse teeth (67.64%), and Mongolian spots (64.71%). There were two clinical manifestations that were significantly different between IIIA and IIIB: Hepatosplenomegaly and serrated teeth. The most common initial symptoms at diagnosis were speech delay (52.94%), hyperactivity (35.29%), and mental retardation (29.41%). Genetic analysis of 25 patients was conducted, which identified 12 novel mutations. Conclusion When language retardation, mental retardation, and rough facial features occurred, MPS III should be considered. At same time, more examination should be operated, such as examination of changes in cranial magnetic resonance imaging of cerebral cortex atrophy. Hepatosplenomegaly and serrated teeth could be used clinically to preliminarily distinguish IIIA from IIIB.
