Résumé

McCune Albright Syndrome (MCAS) is an association of, Café-au-lait macules, polyostotic fibrous dysplasia and autonomous hyperfunctioning endocrinopathy. This is a rare disorder seen more commonly in females. We evaluated 7 (6F & 1M) cases under six years of age (4 months to 5.5 yrs) presenting with Café-au-lait spots, polyostotic fibrous dysplasia and/or sexual precocity. All the 7 cases had large Café-au-lait spots, radiologic features of polyostotic fibrous dysplasia were seen in 5 cases. Six girls had precocious puberty with large ovarian follicles and elevated S. Estradiol levels (14-65 pg/dl) with prepubertal gonadotropin levels in 5 of them. Medroxy-progrestrone acetate was used to treat the sexual precocity. Five girls on follow up for 6 months (6mo-16mo) showed cessation of menstrual episodes and regression of ovarian follicles in three, regression in breast size in one, and three girls continued to grow at a height velocity >95th centile for age. Skeletal lesions and skin features did not show any change. No other endocrinopathy was noted. Gonadotropin independent precocious puberty was the only endocrine affection seen in this series.

Résumé

OBJECTIVE: To study the clinical, biochemical, hormonal, radiological and histopathological profile of adrenocortical tumors in children; to assess the clinicopathological correlations and note the future outcome. DESIGN: Retrospective and prospective study. SETTING: Hospital based; Endocrine Service of our institution and other institution based services. SUBJECTS: 14 children (Females = 11, Males = 3) with adrenocortical tumor, aged 8 months to 13 years (mean age 5.1 +/- 3.42 years), seen over a period of 9 years. RESULTS: Females predominated (F:M = 3.7:1). Majority (64%) had a mixed picture with cushingoid features and virilization, whereas 36% presented only for virilization. Elevated serum cortisol levels with loss of diurnal variation was noted only in those with mixed clinical presentation. Adrenal androgen elevation was noted in majority of cases as virilization was common to all. CT confirmed the diagnosis of tumor, 7 on either side. Thirteen cases were operated. Histopathologic diagnosis was carcinoma in 7 and adenoma in 6 cases. Three of the seven with carcinoma died within 3 months to 2 years but two of these with small tumours (weight 60-65 g and diameter < 6 cm) were well at 2 and 5 years, while as one of the six with a large adenoma had recurrence and metastasis after three years. CONCLUSION: Female preponderance was marked (4 times), 43% of tumors had occurred by 3 years of age and 64% by 6 years. Neither the hormonal parameters nor the histopathology correlated well with the biological behavior and outcome. Prolonged and vigilant follow up is essential.

Résumé

A total of 25,244 full term consecutive newborns were screened for hypothyroidism at 24 to 96 h of birth using the filter paper technique for thyroxine. The screening protocol based on our pilot study considered filter paper thyroxine (FP-T4) values of 51 to 80 ng/ml (-1 SD) as borderline and < 50 ng/ml (-2 SD) as high risk for congenital hypothyroidism. FP-T4 and/or serum T4 and TSH were reestimated in all neonates with FP-T4 < 80 ng/ml. A total of 4775 (18.9%) newborns (FP-T4, 51 to 80 ng/ml in 4435 and < 50 ng/ml in 340) needed the recall; 2237 (50.4%) with FP-T4 51 to 80 ng/ml recalled by letters and 283 (83.3%) of the 340 subjects with FP-T4 < 50 ng/ml recalled by home visit, responded by 6 wk of age. Congenital hypothyroidism was confirmed in 6 newborns. FP-T4 in one persisted at 55 ng/ml on follow up and in the remainder both initial and repeat values were < 50 ng/ml. Follow up serum T4 values were subnormal (7.8-50.2 ng/ml) and serum TSH elevated (80-1233 IU/ml). Technetium thyroid scan showed agenesis in 3, ectopia in 2 and normal gland with probable dyshormonogenesis in one. Three other newborns (FP-T4 93 to 143 ng/ml) escaped primary detection and were referred later for congenital hypothyroidism. The incidence of congenital hypothyroidism by primary screening was 1:4207 (6 of 25,244) but with these 3 missed cases, probably 1:2804. Congenital hypothyroidism was reconfirmed in all 9 infants between the ages of 2 1/2 to 4 yr.(ABSTRACT TRUNCATED AT 250 WORDS)

Résumé

Eighty children (58 girls and 22 boys) with isosexual precocity seen in the past eight years were evaluated clinically and investigated to identify the underlying cause. Of these, 50% (29 girls and 11 boys) had centrally mediated true precocious puberty (TPP). The girls could be classified into five major groups (I) Central precocious puberty 29-subclassified into idiopathic (ITPP, 15) and organic or neurogenic (NTTP, 14), (II) Premature thelarche (PT, 20), (III) Premature menarche (PM, 2), (IV) Premature adrenarche (PA, 5), and, (V) Others: hypothyroid (n = 1), and McCune Albright Syndrome (n = 1). ITPP as a cause of precocity in girls was seen less often (52%) and NTPP more often (48%) compared to most Western series, with tubercular meningitis as the cause in 31% and hypothalamic hamartomas in 10%. Though the LH and estradiol levels were significantly higher (p < 0.05) in TPP, compared to PT, these were not helpful in differentiating because of considerable overlap. LH-predominant-response (LH/FSH ratio > 1) to LHRH testing was seen in TPP. Amongst the 22 boys, 11 (50%) had TPP, ITPP in 27% and NTPP in 73%. Hamartomas (n = 4) and TBM (n = 3) contributed equally to NTPP; pineal tumor was seen in one. The adrenal (n = 7) and testicular (n = 2) causes together involved 41% of the boys with precocity, congenital adrenal hyperplasia (CAH) CAH, 11-beta hydroxylase being the commonest cause. Of the 6 boys witdeficiency was found in four and nonsalt losing form of 21-hydroxylase deficiency in 2. Testicular and adrenal tumors and testotoxicosis were noted in one case each. The etiologic factors were more varied in boys.

Résumé

Ten children, five boys and five girls with true precocious puberty at an early age were found to have hypothalamic hamartomas on brain imaging. Very early onset of puberty, varying from a few weeks to three years of age, and rapid progression were characteristic. Accelerated growth velocity and markedly advanced bone age were evident in all. Gonadotropin and gonadal hormone levels were elevated above the prepubertal range. Six children had associated developmental delay or hyperactivity.

Résumé

This study prospective without any selection bias included 80 of the 152 hypothyroid infants and children seen over the past six years. The clinical diagnosis was confirmed by TSH and thyroid hormone (T3, T4) studies. Scanning for thyroid with TC99m pertechnetate was carried out in all except seven older children with grade II and III goiters where 131I uptake studies were done. Serum thyroglobulin (RIA) was estimated and antithyroglobulin and antimicrosomal antibodies were tested. Based on thyroid 131I scan or 131I uptake, 52.5% had no demonstrable thyroid tissue except one with hypoplasia (Group I, n = 42), 25% had ectopic thyroid (Group II, n = 20), and 22.5% had normal or enlarged thyroid gland (Group III, n = 18). One hypothyroid patient of Group III had thyroiditis with high antibody titre and one was proved to have iodine deficiency). The mean age at time of diagnosis was lowest in Group I (age in months--30.3 +/- 36.2; 60.6 +/- 53.9; 106.2 +/- 69.3 in Groups I, II and III respectively. The intergroup differences in age were significant. The mean serum Tg levels increased progressively from Groups I to III. In the present series thyroid dysgenesis led to hypothyroidism in 77.5%, with athyreosis in 52.5% and ectopia in 25%. Dyshormonogenesis was noted in 20% and thyroiditis in 1.5%.
