Background: The number of adolescent patients with anorexia nervosa is increasing. In addition, an increase in pre-adolescent patients with premenarchal onset has also been recognized. Detection of the disease in childhood and adolescence, however, is not always easy because the symptoms are not characteristic during this period.

Method: We analysed the nucleotide sequences of the IGF1R gene of the family.
Mutation in the orphan nuclear receptor DAX-1 gene causes X-linked adrenal hypoplasia congenita (AHC). Affected male children classically suffer a salt-losing crisis and adrenal insufficiency in their early infancy or, in some rare exceptions, with late-onset subtype. We report here a patient manifesting late-onset adrenal hypoplasia congenita caused by the premature truncation of the C-terminus of the DAX-1 molecule, which is essential for its function as a transcriptional repressor.

Initial neuroimaging revealed the presence of brain edema with high signal changes in the fronto-parietal cortex on diffusion-weighted MRI. The brain edema worsened four days into admission, and by day 14 low-density areas were seen over the frontal lobes bilaterally using computed tomography (CT).

In the present study, genotypes of beta(3)-adrenergic receptor (beta(3)AR) and of melanocortin-4 receptor (MC4R), both of which are believed to have a close link to the cause of obesity, were analyzed and compared with phenotypes of childhood obesity.
Methods: Thirty-five obese children with moderate to severe obesity were enrolled.
A 6-month-old boy with persistent primitive trigeminal artery (PPTA) presented with stridor, dysphagia, delayed motor development and postural neck and shoulder dystonia. Magnetic resonance imaging/angiography and ultrasonography revealed PPTA, with flow from the dilated basilar artery to the right internal carotid artery, lower brainstem compression by the dilated basilar artery, and cerebellar vermis hypoplasia. Evoked potentials showed lower pons and medulla oblongata functional disruption.

When an object was moved towards her mouth, or when the corner of her mouth was stroked with a tongue depressor, she would immediately open her mouth fully and hold it open. This reaction appeared transiently during the course of her illness in association with other frontal release signs including the rooting, groping and palmomental reflexes.

Objective: We hypothesized that mutations of IGF-IR gene might predispose to short stature in children born with intrauterine growth retardation (IUGR).
Patients: Twenty-four children with unexplained IUGR (birth weight < -1.
We present a 3-yr-old girl with a virilizing adrenocortical carcinoma invading into the right atrium with histological high-grade malignancy and p53 mutation. Development of facial acne and pubic hair were noted at 3 yr and 2 mo. The levels of androgens were high.

Fat areas at the ulnar, triceps, thigh, and calf regions were measured in normal weight prepubertal children (P) and adolescents (N), and overweight adolescents (O). There were significant differences in fat areas at the four sites between N and O of both sexes, especially in the proximal extremities (triceps, thigh) in boys.

Means and standard deviation (SD) were calculated after logarithmic transformation of the original skinfold readings to demonstrate stature-based standards of SFT in Japanese children. The means of SFT exhibited nadirs (boys/ girls: ulnar 5.
