Background: A recent study suggested that sexual dimorphism affects initial thyroid function in congenital hypothyroidism (CH) but differs according to aetiology of CH. Aims: To determine if sexual dimorphism was associated with biochemical severity of CH and its aetiology in our large British population. Methods: We examined retrospectively the initial thyroid function tests of 140 infants diagnosed with CH from screening. All infants underwent Tc-pertechnetate radionuclide scans at diagnosis to establish the aetiology of CH prior to commencement of treatment. Patients were classified into athyreosis, ectopia and presumed dyshormonogenesis on the basis of thyroid scans. A comparison of males and females were made within the three aetiological groups for gestational age, birth weight, initial dose of levothyroxine (LT4), screening TSH, confirmatory plasma thyroxine (T4), confirmatory plasma TSH and age of TSH suppression. Results: There was no significant difference between sexes for gestation, birth weight and initial treatment dose in all aetiological subgroups. In thyroid ectopia, screening TSH and confirmatory plasma TSH were significantly higher in females compared with males (P < 0.01), while confirmatory plasma T4 were significantly lower in females (P < 0.05). No difference was detected between males and females in athyreosis and dyshormonogenesis subgroups for screening TSH, confirmatory plasma TSH and total T4. Conclusion: Sexual dimorphism influenced the biochemical severity of thyroid ectopia in congenital hypothyroidism in our British population. However, this effect was not apparent in patients with athyreosis or dyshormonogenesis. Further advances in the molecular genetics of CH are essential to evaluate this phenomenon further.

Objectives: Congenital hypothyroidism (CHT) is one of the major endocrine and metabolic disorders in neonates. Delayed diagnosis and treatment of CHT may lead to certain neuro-developmental disorders. Study Design: Prospective study. Setting: NICU of Children Hospital, Institute of Child Health Multan, Pakistan. Period: September 2018 to November 2019. Material & Methods: A total of 142 neonates of both gender having birth weight of less than 1500 grams were enrolled in this study. Thyroid function tests, like TSH, free T4 and T4 levels were performed in all these neonates between 1- 5th day, 2nd week and 4th week of life by radioimmunoassay. Results: Out of 142 neonates, 76 (53.5%) were male and 66 (46.5%) female. Mean gestational age was 31.41+1.93 weeks while mean birth weight was found to be 1261.53 + 170.36 grams. Gestational age of < 28 weeks was noted in 9 (6.3%) neonates, 28 to <30 weeks in 59 (40.4%), 30 to 32 weeks in 33 (23.2%) and 41 (28.9%) were above 32 weeks. Thyroid function disorders were noted in 89 (62.7%) neonates while transient hypothyroxinemia was the most common one, found in 65 (45.7%) neonates, transient hyperthyroxinemia in 12 (8.4%) and Congenital hypothyroidism (CHT) in 12 (8.4%). Nasal continuous positive airway pressure (NCPAP) was used for treating respiratory distress syndrome (RDS) in 107 (75.4%) neonates. Surfactant administration was done in 69 (48.6%). Patent ductus arteriosis (PDA) was noted in 27 (19.0%), intraventricular hemorrhage (IVH) in 8 (5.6%) and culture proven sepsis was seen in 18 (12.7%). Conclusion: In low birth weight / preterm neonates, thyroid function disorders are quite common. Transient Hypothyroxinemia was noted to be the most common disorder and congenital hypothyroidism was present in 8.4% of neonates.

Abstract Objectives To investigate the association of calcium supplementation during the pregnancy with the birth weight of single-born neonates. Methods The survey employed a multistage, stratified and random sampling to investigate 15–49 aged pregnant women in 2010 to 2013 in Shaanxi province. A self - designed questionnaire was utilized. Birth weight between the 10(th) and 90(th) percentile was classified as appropriate for gestational age(AGA) infants. Chi-square test and logistic regression models were conducted to evaluate the association of calcium supplementation with single-born neonatal birth weight. Results A total of 28,490 women was enrolled in this study, 17 349 (60.9%) of participants had calcium supplementation during pregnancy. The incidence rates of small and large gestational age infants were 13.5% and 8.3%, respectively. The study conducted that calcium supplementation had a statistically significant difference in SGA (birth weight percentile &lt;10) (P &lt; 0.01). After adjusting the regression models by confounding factors, we found that calcium supplementation was still protective towards SGA birth, the difference was statistically significant (OR = 0.89, 95% CI: 0.82–0.96, P &lt; 0.05), but there was no significant difference in the birth to LGA (birth weight percentile &lt;10). Conclusions Calcium supplementation during pregnancy reduced the risk of SGA, but was not associated with the birth of LGA. Funding Sources

Abstract Objective To assess the effect of fetal gender in small-for-gestational age (SGA) neonates with birth weight less than the fifth percentile by gestational age. Methods We compared male and female SGA neonates for maternal and neonatal outcomes in the following gestational age subgroups: at <32 + 6, 33 + 0–36 + 6 and at ≥37 + 0 weeks of gestation. Results We examined 159, 154 and 2363 SGA neonates born at <32 + 6, 33 + 0 to 36 + 6 and ≥37 weeks of pregnancy, respectively, whose birth weight was below the fifth percentile for gestational age and who met our inclusion criteria. Overall, there were no significant differences between the mothers of males and females, except that there were more males at term and the incidence of nulliparas was greater among the mothers of males. In terms of outcomes, males had a similar incidence of respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH) and admissions to intensive care. Interestingly, low Apgar scores were more common in preterm females born at 33–37 weeks and vice versa in births over 37 weeks. Conclusion Our data do not support an advantage of either gender in preterm birth of infants who are most likely growth restricted.

Abstract Background: Intrauterine growth patterns are influenced by maternal thyroid function during gestation and by fetal sex. It is unknown, however, whether the relationships between maternal thyrotropin (TSH) and free thyroxine (fT4) levels in early pregnancy and fetal growth outcomes are modified by fetal sex. Design: Data were obtained from a community-based cohort study of pregnant women living in Amsterdam (Amsterdam Born Children and Their Development study). TSH and fT4 levels were determined during the first prenatal screening at median 13 weeks (interquartile range, 12 to 14). Women with live-born singletons and no overt thyroid dysfunction were included (N = 3988). Associations between these maternal hormones and birth weight, small for gestational age (SGA), and large for gestational age (LGA) were analyzed separately for each sex. Results: After adjustments, 1 pmol/L increase in maternal fT4 levels was associated with a reduction in birth weight of 33.7 g (P &lt; 0.001) in male newborns and 16.1 g (P &lt; 0.05) in female newborns. Increased maternal fT4 was not associated with increased odds for SGA, but was associated with a decreased odds for LGA in boys [per 1 pmol/L; odds ratio (OR), 0.79; 95% confidence interval (CI), 0.69 to 0.90]. Maternal subclinical hypothyroidism in early pregnancy (TSH &gt; 2.5 mU/L, 7.3%) was associated with increased odds for LGA in male newborns (OR, 1.95; 95% CI, 1.22 to 3.11). Conclusion: Maternal fT4 in early pregnancy was observed to be inversely associated with birth weight, with a stronger relationship in males. Male infants also had increased odds for LGA in mothers with subclinical hypothyroidism. Sexual dimorphism appears to be present in the relationship between maternal thyroid metabolism and fetal intrauterine growth, with stronger associations in male infants.

Objective: To compare the mean hemoglobin levels and frequency of polycythemia in full term neonates after early and delayed cord clamping. Study Design: Randomized Controlled Trial. Setting: KRL General Hospital Islamabad (Labor Room/ Neonatology). Periods: December 2017 to June 2018. Material & Methods: 190 full term neonates were selected and divided into 2 equal groups randomly: Early cord clamping group after delivery and late cord clamping group. Two hours after clamping the venous blood samples were taken for the hemoglobin and hematocrit levels. Mean and standard deviation were calculated for gestational age, birth weight, hemoglobin and hematocrit. Frequency and proportions were calculated for gender and polycythemia. Results: Mean gestational age of the mothers was 39.27 ± 1.50 weeks. Of 190 neonates, 91 (47.9%) were males, 99 (52.1%) were females. Mean birth weight was 3.64 ± 0.72 kg while mean Hb and HCT levels were 16.07 ± 2.30 g/dl and 63.26 ± 5.32% respectively. Keeping cut off value of 13.5 g/dl of Hb to label anemia or no, 35 (18.4%) neonates were anemic in this study. The polycythemia (HCT >65%) was present in 72 (37.9%) of neonates. There was no difference between groups in terms of gender, anemia, gestational age and birth weight (p values 0.663, 0.852, 0.700 and 0.491 respectively). The distribution of polycythemia was different among groups (p value 0.007). The mean hemoglobin level in group A was 15.52 ± 1.90 g/dl while in group B it was 16.62 ± 2.53 g/dl (p value 0.001). Mean Hb levels were statistically not different among some of the groups (gestational age <40 weeks, birth weight <4 kg) while HCT levels are significantly different among male group and category of birth weight >4 kg. Rest of the stratification groups showed significant difference. Conclusion: The delayed cord clamping in neonates results in increased mean hemoglobin and hematocrit levels with increased frequency of polycythemia as compared to early cord clamping.

According to national neonatal perinatal data (NNPD) the survival of ELBW babies has improved from 37% in 2000 to 45% in 2002-3 reports. In our neonatal unit in PGIMER the survival of ELBW babies has been 54-56% in last 5 years, however unfortunately there is very scanty reports of long term outcome of ELBW babies from India. There is very scanty report of long term growth outcome of VLBW and ELBW Babies in our country, we reported VLBW and ELBW babies in our follow up had poor catch up growth, though some catch-up was observed at 6 month but subsequent lag in growth probably reflects poor weaning at 1 year.  Infants with extremely low birth weights (ELBWs) are more susceptible to all of the possible complications of premature birth, both in the immediate neonatal period and after discharge from the nursery. These babies are at risk of poor growth and developmental. in the present study a total of 39 cases of ELBW Babies were enrolled during one year study period from July 2011- June2012 attending the neonatal follow up clinic attained 2year±3month of corrected age. Their detail birth data and postnatal illnesses retrieved from their initial hospital files and unit discharge record. A similar number of babies enrolled at 2yrs±3months of age in the control group. In the presence study, we assessed the growth, and neurological out come in extremely low birth baby attained 2yrs±3 months of corrected age. The study population consisted of 39 children of ELBW baby born during 2009 -10 at PGIMER & same number of normal birth weight children at 2yr±3 months of corrected age who satisfied the inclusion and exclusion criteria. These children were enrolled from neonatal follow up clinic who were already undergoing long term follow up. For growth outcome, we used weight, height & head circumference measurement of child, for neurological and developmental outcome used clinical neurological examination and DP-III .Base line demographic characteristics of our ELBW babies (Cases) where as follows.   Mean (S.D) gestational age of  ELBW babies was 29.87±2.3 week. Mean (S.D) birth weight 867±71.1 grams, Mean (S.D) lenght35±2.1cm & head circumference was 25.76±1.9 cm. Mean hospital stay in the ELBW babies was 48.6±19.9 days. Mean birth weight and gestational age of control group where 2684±166.2grm and 39.03±0.9 weeks. At 2year of corrected age we found  - Weight was similar in both in case group & control group. (10.04±1.4 Vs 10.75±1.1). Height and head circumference were smaller in cases than control group. (81.4±4.3 Vs 84.4±3.3 and 45.9±1.6 Vs 46.8±1.5. 5% Babies had cerebral palsy in case group (N=2/39) and none in control group. Gross development score(GDS) in Development profile-III in both study group (cases & controls) was  similar  (72.49±8.08 Vs 73.54±9.3,p=0.596). Significant difference in domains physical (84.5±7.8 Vs.90±3.5, p=0.000) and domains adaptive (81±6.7 Vs. 85.3±5.4,p= 0.003) in cases as compared to controls. There was no difference between SGA and AGA among cases in growth and neurological development. There was no difference between male and female in case group in any parameter .There is very scanty data from our country on longterm follow up of ELBW babies. Our data shows that our ELBW cohort remained small in height and had smaller head circumference though weight was similar as compared to normal control babies.  Key words: ELBW, VLBW, birth weight, neurological examination.

Objective. The aim of this study was to investigate the relationship between different psoriasis types and thyroid dysfunction. Methods. The data of patients diagnosed with psoriasis between January 2013 and October 2018 who underwent thyroid function tests were collected. Free triiodothyronine (FT3), free thyroxine (FT4), total triiodothyronine (TT3), total thyroxine (TT4), thyroid-stimulating hormone (TSH), thyroglobulin antibody (TGAb), and thyroid peroxidase antibody (TPOAb) were measured. The thyroid function of patients with psoriasis vulgaris, pustular psoriasis, erythrodermic psoriasis, and psoriatic arthritis was evaluated, and the differences in hormone levels and antibodies in the pituitary-thyroid axis with psoriasis type were analyzed. Results. The data of a total of 468 patients were analyzed in this study. The proportion of normal hormone levels was higher among vulgaris patients ( P < 0.001 ), while the erythrodermic patients were more likely to have decreased FT3 or FT4 but normal TSH ( P < 0.001 ). FT3 levels were lower in pustular patients ( P < 0.05 ), FT4 levels were lower in erythrodermic patients ( P < 0.05 ), and TSH levels were higher in patients with psoriatic arthritis ( P < 0.05 ). TPOAb levels were higher than normal in all patients, but there was no significant difference in the levels of TPOAb and TGAb among 4 types of the patients. Conclusion. Psoriasis is related to thyroid dysfunction, especially in patients with atypical psoriasis types. The possibility of complications should be considered in erythrodermic patients.
