Natural history and parental experience of children with trisomy 18 based on a questionnaire given to a Japanese trisomy 18 parental support group.

We conducted a questionnaire-based study in collaboration with a Japanese trisomy 18 parental support group. Sixty-five children (female, 68%) with full trisomy 18 were evaluated. Diagnosis was made prenatally in 17% (11/65) and 57% (37/65) were born following a cesarean.

Lack of an association between E-selectin gene polymorphisms and risk of Kawasaki disease.

Background: Coronary artery lesions (CAL) are a serious complication of Kawasaki disease (KD). The increased serum E-selectin level during the acute phase of KD and the association of E-selectin gene (SELE) polymorphisms with the prevalence of coronary artery disease in adults suggest a possible association between SELE polymorphisms and the development of CAL in KD patients.

Methods: The subjects consisted of 177 KD patients, including 59 with and 118 without CAL, and 305 healthy controls.

[Case of drug-induced hypersensitivity syndrome due to lamotrigine: demonstration of sequential reactivation of herpesviruses].

Drug-induced hypersensitivity syndrome (DIHS) is a rare but severe multiorgan disorder. The reactivation of human herpesvirus-6 (HHV-6) and other human herpesviruses has been reported to be associated with its pathogenesis. We herein report a case of 14-year-old female who developed DIHS during the treatment with lamotrigine, a novel antiepileptic drug.

Familial brain arteriovenous malformation maps to 5p13-q14, 15q11-q13 or 18p11: linkage analysis with clipped fingernail DNA on high-density SNP array.

Familial arteriovenous malformations (AVM) in the brain is a very rare disease. It is defined as its occurrence in two or more relatives (up to third-degree relatives) in a family without any associated disorders, such as hereditary hemorrhagic telangiectasia. We encountered a Japanese family with brain AVM in which four affected members in four successive generations were observed.

Molecular karyotyping in 17 patients and mutation screening in 41 patients with Kabuki syndrome.

The Kabuki syndrome (KS, OMIM 147920), also known as the Niikawa-Kuroki syndrome, is a multiple congenital anomaly/mental retardation syndrome characterized by a distinct facial appearance. The cause of KS has been unidentified, even by whole-genome scan with array comparative genomic hybridization (CGH). In recent years, high-resolution oligonucleotide array technologies have enabled us to detect fine copy number alterations.
