Postnatal Assessment of Minipuberty in Indian Preterm and Full-term Male Infants.

OBJECTIVES: To study the differences in the timing and magnitude of postnatal urinary gonadotropins and testosterone secretion during minipuberty in Indian preterm (PT) and full-term (FT) male infants. METHODS: This prospective observational study included 30 PT and 60 FT male infants. Urinary luteinizing hormone (LH), follicular stimulating hormone (FSH), and testosterone, and stretched penile length (SPL) and testicular volume (TV) were measured on day 7, first month, second month, fourth month and at six months of age. RESULTS: The highest elevation of mean (SD) urinary LH was observed in PT infants in comparison to FT infants [12.6 (1.4) vs 4.9 (0.6) µIU/mg, respectively; P < 0.001] in the first month. FSH levels were lower in PT than FT infants on day 7 (P < 0.001). Testosterone was significantly elevated in PT than FT infants [70.8 (5.6) vs 44.6 (3.2) ng/mg; P < 0.001] with a greater mean percentage increase in SPL (P < 0.001) and TV (P < 0.001) by the first month. CONCLUSIONS: Indian PT male infants showed a greater increase in urinary LH and testosterone, with a faster increase in SPL and TV.

Bloom's syndrome with growth hormone deficiency: a rare association.

We report a case of a 5-year-old boy presenting to us with short stature. He was born of consanguineous parentage and was small for gestational age. He had severe short stature, with height Z score of -6.2 SD Score, markedly delayed skeletal age, low level of insulin-like growth factor 1, unstimulated growth hormone and hypoplastic anterior pituitary gland on MRI. He was advised growth hormone (GH) replacement at 2 years of age, but he did not receive it . Later on, he developed photosensitive telangiectatic lesions over face and required multiple hospital admissions for recurrent systemic infections. Genetic analysis confirmed the diagnosis of Bloom's syndrome. The present case report illustrates the need for high vigilance for conditions like Bloom's syndrome in growth hormone deficiency (GHD), in whom GH treatment could potentially be harmful. Bloom's syndrome with GHD is an exceedingly rare association.
