Third-Generation Thyrotropin Receptor Antibody (TRAb) assay for predicting neonatal thyroid dysfunction in pregnant women with Graves' disease.

PURPOSE: The aim is to validate the third generation Thyrotropin receptor antibody (TRAb) assay for predicting neonatal thyroid dysfunction and adverse pregnancy outcomes in pregnant women with Graves' disease. METHODS: This prospective cohort study was conducted in TRAb positive pregnant women with Graves' disease and their off springs. The primary outcome was to assess different forms of neonatal thyroid dysfunction in relation to maternal and neonatal TRAb levels. The secondary outcome was to predict adverse pregnancy outcomes by using maternal TRAb levels. Serum T3, FT4, TSH, TRAb levels were measured using electrochemiluminescence immunoassay. RESULTS: 51 pregnant women were included. Five women had adverse pregnancy outcomes, TRAb levels of > 19.06 IU/L (10.9 times the upper limit of normal (ULN)) predicted adverse pregnancy outcomes with 100% sensitivity and 93.5% specificity. Among the 46 successful live births, 13 (28.3%) had neonatal thyroid dysfunction. Out of 13 neonates, 7 (32%) had neonatal thyrotoxicosis, 4 (18%) had primary hypothyroidism, and 2 (9%) had central hypothyroidism. Third trimester maternal TRAb levels of > 7.99 IU/L (4.6 times the ULN)and day three neonatal TRAb levels of > 5.03 IU/L (2.9 times the ULN), predicted the neonatal thyrotoxicosis with 100% sensitivity and 97.4% specificity. CONCLUSION: Very high maternal third generation TRAb levels strongly predicted the adverse pregnancy outcomes and neonatal thyroid dysfunction in pregnant women with Graves' disease. Neonatal thyroid function test along with the TRAb levels strongly correlated with different forms of neonatal thyroid dysfunction and is very useful in avoiding inadvertent treatment to neonates.

Clinico-radiological correlation of pituitary stalk interruption syndrome in children with growth hormone deficiency.

PURPOSE: To analyze the clinical, hormonal, and radiological characteristics of Pituitary stalk interruption syndrome (PSIS) in children with growth hormone deficiency (GHD). METHODS: This is a prospective cross-sectional study, conducted over a period of three years in a short stature clinic of tertiary care referral hospital. 57 severe short stature children with proven GHD were included in the study. RESULTS: Among 57 children with GHD, 14 (24%) were diagnosed as PSIS. The mean age at diagnosis was 11.8 ± 2.6years. The male to female ratio was 2.5:1. Nine (64%) children had multiple pituitary hormone deficiency (MPHD) and 5 (36%) had isolated growth hormone deficiency (IGHD). In spite of absent or ectopic posterior pituitary (EPP)in Magnetic Resonance Imaging (MRI) of PSIS cohorts, only one had Arginine vasopressin (AVP) deficiency. EPP was seen near median eminence in 6 (44%), elsewhere in 4 (28%), and absent in 4 (28%)children. The height gain following growth hormone therapy was better in PSIS cohorts as compared to non-PSIS. CONCLUSION: Male gender, breech presentation, external congenital anomalies like cryptorchidism, midline defects and nystagmus were more common in children with PSIS. MPHD were more frequently seen in PSIS whereas IGHD in non-PSIS cohort. AVP deficiency is very rare in PSIS despite of absent or ectopic posterior pituitary in MRI. High index of clinical suspicion in all severe short stature may lead to early diagnosis and prompt initiation of growth hormone treatment for better outcome.

A randomized controlled trial comparing myoinositol with metformin versus metformin monotherapy in polycystic ovary syndrome.

OBJECTIVE: Insulin resistance and hyperinsulinemia plays an important role in pathogenesis of polycystic ovary syndrome (PCOS). Metformin, Myoinositol and d-chiro-inositol acts as insulin sensitizers and exerts a beneficial effects in PCOS. The objective is to compare the effect of metformin monotherapy versus a combination of metformin with Myoinositol and d-chiro-inositol in PCOS. DESIGN: This study is a randomized controlled trial conducted over a period of 6 months. All overweight and obese women with PCOS with the age group between 18 and 35 were included and randomized into two groups, 27 in the metformin monotherapy arm and 26 in the myoinositol combination arm. PATIENTS AND MEASUREMENTS: The variables assessed were duration of menstrual cycle, anthropometric parameters, modified Ferriman Gallwey score, global acne score, Fasting insulin, HOMA-IR, fasting lipid profile, serum testosterone, sex hormone binding globulin, luteinizing hormone, follicle stimulating hormone, anti-Mullerian hormone, and pelvic ultrasound to assess ovarian volume, PCOS Questionnaire score. Changes in the parameters from baseline at the end of 6 months of treatment were assessed and compared between the groups. RESULTS: Menstrual cycle regularity improved in both groups with significantly greater improvement in the group receiving myoinositol-based therapy (p < .001). Pregnancy rate was equal in both the arms. There was a significant improvement in PCOSQ score in myoinositol-based therapy group (p < .001). However, there was no statistically significant difference in other hormonal, metabolic parameters between two groups in spite of symptomatic benefits. CONCLUSIONS: The addition of myoinositol to metformin exerts additional benefits in improving menstrual cycle regularity, and quality of life in women with PCOS.

"Congruency the ART of Being Real" - 46XY DSD Due to 5 α Reductase Deficiency - Challenges in Decision Making.

Disorders of sexual development (DSDs) are heterogenous group of disorders characterized by discrepancy in chromosomal, gonadal, and phenotypic sex. DSD is a Medico-Social Emergency. 5 α reductase type 2 deficiency is one of the rare causes of 46 XY DSD. The degree of under virilization varies from clinically female to a near male phenotype. Müllerian structures were absent. At puberty, there might be features of virilization. Gender incongruence or dysphoria occurs frequently during puberty. An important marker for diagnosis is an elevated testosterone to dihydrotestosterone ratio in the basal state or following HCG stimulation. All 46 XY DSD require an appropriate molecular diagnosis prior to gender assignment and gender reassignment surgery. Gender reassignment surgery and/or Gonadectomy should be performed only after 18 years if there are compelling indications like suspicion of malignancy or presence of gender dysphoria or gender incongruence.
