RESUMEN

PURPOSE: To analyze the effects of clinical and laboratory factors, including insulin-like growth factor (IGF) levels, on the height velocity of normal prepubertal children. METHODS: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age was 6.3±1.4 years, with a height standard deviation score (SDS) of -0.88±0.70. IGF-1, IGF binding protein-3 (IGFBP-3), SDS for anthropometric measurements, and changes in SDS for anthropometric measurements were analyzed for 1 year, and their associations with 1-year height velocity were investigated. RESULTS: The group of children with a 1-year height velocity of ≥6 cm were chronologically younger than the group with a 1-year height velocity of < 6 cm (5.9±1.3 years vs. 6.7±1.3 years, P=0.004), with a lesser increase of SDS for body mass index (BMI) over 1 year (-0.18±0.68 vs. 0.13±0.53, P=0.014). There were no differences between the 2 groups in IGF-1 SDS and IGFBP-3 SDS. Multiple linear regression showed that baseline chronological age (r=0.243, P=0.026) and height SDS (r=0.236, P=0.030) were positively associated with IGF-1 SDS. Binomial logistic regression showed that an older chronologic age at referral (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.47–0.99) and an increase of BMI SDS over 1 year (OR, 0.41; 95% CI, 0.18–0.89) were associated with a decreased growth possibility of an above-average height velocity (≥6 cm/yr). CONCLUSIONS: Height velocity of normal prepubertal children is affected by an increase of BMI SDS and chronological age. Prepubertal IGF-1 SDS reflects height SDS at the time of measurement but is not associated with subsequent height velocity.

RESUMEN

Familial adenomatous polyposis (FAP) is a precancerous clinical entity, which is characterized by the development of numerous adenomatous polyps throughout the colon and rectum. The majority of FAP are associated with mutations of the adenomatous polyposis coli (APC) gene. Until now, more than 1,000 different APC mutations have been reported and some mutations express attenuated phenotypes which are milder forms with 10~100 colorectal polyps. We identified a novel mutation of APC gene which expressed an attenuated FAP but caused large gastroduodenal tubular adenomas requiring repeated endoscopic resections. A 16-year-old girl was referred to Incheon St. Mary's Hospital for evaluation of gastric polyposis. Initial esophagogastroduodenoscopy (EGD) showed numerous gastric polyps in the fundus and upper body and a few polyps in the duodenum. Pathologic examination confirmed gastric polyps as fundic gland polyps and duodenal polyps as tubular adenomas. Only a few colonic polyps of 2 to 5 mm in size were found on colonoscopy. Genetic analysis using polymerase chain reaction and direct sequencing revealed a novel stop codon mutation at codon 1522 in exon 16 of APC gene. At 12-month, 18-month, and 35-month follow-up EGD, large duodenal polyp and gastric polyps were removed endoscopically.
