It is well known that fat children tend to be taller than their peers and to present a slight acceleration of skeletal and pubertal maturation. To verify this tendency and to examine some of the points that are still controversial, auxological data were studied concerning 303 subjects (141 males and 162 females, aged 6-16 years) affected by simple obesity. Subjects were seen to be taller than average by about 1 SD from 6 to 9 years of age, becoming close to or shorter than average at later ages. Height below the 10th percentile was common in 17% of males and 8% of females, due to hereditary shortness, growth delay or late puberty. Girls had early puberty and menarche; the rate of sexual maturation was variable in boys.

The data obtained showed that the sequence of development of sacral region ossification was related to gestational age. This observation allows clinicians to accurately exclude isolated sacral agenesis at 16 to 17 weeks of gestation, when the S1-S2 ossification nuclei are visualized. This opportunity may be of particular value in the offspring of diabetic mothers.

We describe a girl with Niikawa-Kuroki (Kabuki) syndrome (NKS) with conical incisors, hypodontia, hypoplastic nails, and brittle hair. Abnormal teeth are common in NKS and support a hypothesis of autosomal dominant inheritance of the syndrome [Halal et al., 1989; Silengo et al., 1996]. Hair abnormalities have never been investigated in NKS. The ectodermal involvement in NKS could represent an important clue for the understanding of the pathogenesis of this syndrome.

Objective: Aim of this study is to examine the 5-year follow-up results of MI PIACE PIACERMI (I like to like and please myself), a cognitive-behavioural programme intended to obtain a weight growth regulation over an extended period. Design: Longitudinal observational clinical study. Setting: Hospital-based programme, through outpatient activities. Subjects: Thirty-one simple obese children, 13 boys and 18 girls, 6-12 years of age on admission. Intervention: The intervention was carried out by a multidisciplinary team (paediatrician, cognitive-behavioural psychologist, physical therapist). It employed cognitive-behavioural techniques, nutrition education, promotion of physical activity, setting a high value on free play in motion. The programme actively involves parents. The following measurements were taken on admission and at 5-year follow-up: height, weight, waist circumference, body mass index (BMI), BMI standardized (BMI-SDS), and adjusted BMI (a-BMI) as actual BMI/BMI (50th percentile) * 100. Dietary habits were investigated by interview and 24-h recall. Parents completed the Family Habit Inventory and the Child Behaviour Checklist (CBCL). Motor skills were assessed by using Frostig's test. Results: The dropout rate was 35.5 %. In subjects who completed the 5-year follow-up, the mean and s.d. of BMI-SDS and a-BMI were, respectively, 4.2370.71 and 54.7%79.0 at baseline and 2.7470.85 and 43.2%717.3 at the last visit. Waist circumference decreased. Family habits improved significantly. Total energy intake was significantly reduced. Emotional and social aspects of obesity-related behaviours showed positive changes. Motor skills globally improved. Conclusions: The study provides further evidence that positive persistent results may be obtained in obese children with treatment programmes combining a lifestyle centred approach, parental involvement, nutrition education and cognitivebehavioural strategies.

Skeletal status by phalangeal quantitative osteosonography (DBM Sonic BP-IGEA) was examined in 1227 healthy children (641 boys and 586 girls) aged 3-16 years. Aims of the study were to evaluate some physical parameters pertaining to the ultrasound transmission crossing the phalanx in a school-age population and to relate these values to age, sex, and growth variables. A correlation was found between AD-SoS (amplitude-dependent speed of sound) and BTT (bone transmission time) and, age, height, weight, and pubertal stage, respectively. No correlation existed between FWA (fast wave amplitude) and SDy (dynamics of the ultrasound signal) and age, height, weight, pubertal stage, and BMI, respectively. AD-SoS increased in boys until 7-8 years of age. Thereafter a plateau was reached up to age 12-13 years, when a rapid increase was observed corresponding to pubertal growth rate acceleration. In girls, AD-SoS increased with age up to 10-11 years with a steeper increase at the time of puberty starting about 2 years earlier than in boys. BTT presented a similar trend. Mean AD-SoS values increased from Tanner pubertal stages 1 to 2 and from stage 3 to 4 in both sexes. Significantly higher mean AD-SoS values in stages 2, 3, and 4 were observed in girls as compared to boys. Mean BTT values increased significantly from stage 1 to 5 in girls and from 1 to 4 in boys. QUS technology showed the ability to assess bone changes in the growing bone.

Modified Greulich-Pyle (GP), Tanner et al. 2, radius, ulna and short bones (TW2-RUS), TW2-20-bone and Roche-Wainer-Thissen RWT (knee) skeletal age assessments were made in an Italian population sample of 128 males and 93 females aged 4.1-16.9 years. All the scales appear to be well-suited to the Italian population despite minor differences. A very high correlation was found between the assessment of knee skeletal ages by the RWT method and that of the hand-wrist by the GP and TW2 systems in the same subject without sex and age-associated variations.
