Preliminary evaluation of thyroid function, utilizing total serum thyroxine (T4) and triiodothyronine (T3) resin uptake, was assessed following delivery in three groups of babies and their respective mothers; 40 premature new-borns with respiratory distress syndrome (RDS), 39 prematures comparable by gestational age who failed to develop RDS, and 22 full-term normal babies. The group of premature newborn infants in whom RDS occurred, as compared to the other two groups, had significantly lower mean total serum thyroxine levels and "free thyroxine index" (T4 x %T3 uptake/100). When matched by gestational age, the differences were also significant. Two days following delivery, the total serum T4 in the surviving prematures with RDS as compared to prematures without RDS was also significantly lower. The mean values for total T4 and "free thyroxine index" in the respective mothers of the three groups were not significantly different. Since L-thyroxine has been shown to increase the production of lung surfactant, widely accepted as deficient in RDS newborn infants, an association between lung immaturity and fetal thyroid function is postulated.

Idiopathic Respiratory Distress Syndrome

We read with interest the recent paper by Papegeorgiou et al.1 We have studied the incidence of the idiopathic respiratory distress syndrome (IRDS) in 132 newborn infants, with gestational ages between 26 and 36 weeks, whose mothers had a urinary estriol (E3) assay during the week prior to delivery. Of the 132, 101 did not receive either antenatal steroid nor any other drug that might have interfered with estrogen synthesis. The urinary E3 excretion was defined as low (< tenth percentile for gestational age) or normal (> tenth percentile).2 The sex incidence is shown in the Table.

Abstract Reports on thyroid function in newborns with respiratory distress syndrome (RDS) are controversial, the significance of obtained results is not clear. Therefore we conducted a longitudinal study of thyroid function in 35 infants with RDS (gestational age 24-36 weeks, birth weights 65o-277o g). 43 well prematures, matched for gestational age, served as controls. No significant differences were observed in cord blood TSH, T3, T4, TBG values and T4:TBG ratios between infants with and without RDS. Prematures with RDS showed lower levels of T3, T4, TBG and T4:TBG at 24 hours of age and increases of TSH values at 72 hours. Subsequently these prematures exhibited a spontaneous rise in thyroid hormone levels. Even non-surviving RDS-infants had initial T3, T4, T4:TBG and TSH values within the normal range. Thyroid hormone concentrations correlated significantly with the severity of pulmonary disease. Depressed thyroid hormone levels were found to be the result and not the cause of RDS. T4 or T3 therapy is not warranted in this condition.

BACKGROUND: Preterm birth remains a major health issue worldwide. Preterm delivery affects over 7–12% of births in India and is responsible for up to 75% of neonatal deaths. Despite advances in medical technology, the prevalence of preterm birth is increasing. Discovery of antenatal corticosteroid for fetal maturation and its adoption into clinical practice highlights several fascinating and universal truths about science and medicine. The challenge in human studies is to demonstrate antenatal corticosteroid administration in pregnancy contributes to developmental programming and how this is manifested in later life. The World Health Organization recommends the use of one course of antenatal steroids for all pregnant women between 26 and 35 weeks of gestation who are at risk of preterm delivery within 7 days. Both, the American College of Obstetricians and Gynaecologists and the Royal College of Obstetricians and Gynaecologists recommend their use between 24 and 34 weeks of gestation (1). The use of antenatal steroids after 34 or 35 weeks of gestation is not recommended unless there is evidence of fetal pulmonary immaturity. Despite this, antenatal steroids are widely used globally across all gestational periods. In a diverse country like India, diversity in clinical practice is a reality. Hence, the present research study intends to study the maternal and perinatal outcomes with antenatal corticosteroid administration in preterm deliveries at Government district hospital, Nandyal in South India. AIMS AND OBJECTIVES Ÿ To determine the incidence of RDS at District hospital, Nandyal among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS and in those whose mothers did not receive ACS. Ÿ To determine the severity of RDS at District hospital, Nandyal among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS and in those whose mothers did not receive ACS. Ÿ To compare the neonatal mortality among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS with those whose mothers did not receive ACS. Ÿ To determine the effectiveness of antenatal corticosteroid administration in preventing early neonatal respiratory distress syndrome in early preterm labour versus late preterm labour. Ÿ To determine the effectiveness of ACS administration in preventing neonatal complications with respect to the mode of delivery. METHODOLOGY: Study was conducted at Government District Hospital, Nandyal from 01/01/2019 to 30/10/2019. A structured questionnaire was prepared under guidance of thesis guide. All pregnant women with gestational age between 28 completed weeks to 37 completed weeks, presenting in OPD either in labour or getting admitted due to any other maternal medical complication, are initially assessed thoroughly to estimate the gestational age by history, LMP, early USG, and clinical examination. They are given a course of ACS if they were not expecting delivery within next 1 hour, after explaining the benets and risks of ACS as per recommendations of Federation of International st Gynecology and Obstetrics. Those who did not receive ACS or those who delivered within 24hrs of administration of 1 dose of ACS were considered as subjects in NACS group. Those who received ACS were considered as subjects in ACS group. After delivery, the neonate is followed up in NICU until discharged or until 7 days whichever is shorter. Mother is followed up for any clinical signs of infection, until she is discharged. Data is analyzed scientically. RESULTS: In Antenatal corticosteroids group (ACS), there were 36 subjects within 20 years, 43 subjects between 20-25 years, 29 subjects between 25-30 years, 25 subjects between 30-35 years. In No Antenatal corticosteroids group (NACS), there were 32 subjects within 20 years, 49 subjects between 20-25 years, 25 subjects between 25-30 years, 10 subjects between 30-35 years. Study observed that Antenatal corticosteroids group had lower incidence of Respiratory distress syndrome compared to No Antenatal corticosteroids group (12.07% versus 23.28%). Antenatal corticosteroids group had lower incidence of severe Respiratory distress syndrome compared to No Antenatal corticosteroids group (21.3 % versus 33.33%) among those who had Respiratory Distress Syndrome. Antenatal corticosteroids group had fewer admissions to NICU than No Antenatal corticosteroids group (20.69% versus 33.62%). Antenatal corticosteroids group had lower mortality than No Antenatal corticosteroids group (12.07 % versus 22.41%). Antenatal corticosteroids group had 35 % less chances of Respiratory distress syndrome compared to No Antenatal corticosteroids group. In No Antenatal corticosteroids group, subjects who underwent vaginal delivery had 10% less risk compared to those who underwent LSCS for their neonates to have Respiratory distress syndrome. In Antenatal corticosteroids group, subjects who underwent vaginal delivery had 14.29 % less risk compared to those who underwent LSCS for their neonates to have Respiratory distress syndrome. Antenatal corticosteroids group had maternal infection rate comparable to No Antenatal Corticosteroids group. CONCLUSION: Use of antenatal corticosteroids was found to be benecial in pregnant women with Gestational age of 28 completed weeks to less than 37 completed weeks at Government District hospital, Nandyal. Antenatal corticosteroids did not have statistically signicant adverse effects (i.e. increased rate of infection) in mothers.

Background. Currently, the development of medicine in the field of perinatology is aimed at improving the quality of medical care for newborns, especially those born prematurely. Premature newborns are most likely to develop hemorrhagic disorders, which often aggravates their condition and determines high morbidity and mortality. On modern hematological analyzers, it has become possible to evaluate a larger number of blood parameters, including platelet parameters, however, there are a small number of studies devoted to the study of platelet parameters in premature newborns. The aim was to study the morphofunctional features of platelets in premature newborns with very low and extremely low body weight. Materials and methods. The study included 78 newborns born at 2534 weeks of gestation, with a body weight of less than 1500 grams. On the 3rd5th day of life, a clinical blood test was performed on the Advia 2120i hematological analyzer (Siemens), with the determination of platelet parameters: PLT, 103 cells/l, PCT, %, PDW, %, Large Plt, 103 cells/l, MPC, g/dl, MRM, pg. Results. In newborns with ELBW, a decrease in the number and granularity of platelets in the blood, an increase in the average dry mass of platelets was found. Newborns with intrauterine growth retardation have a reduced platelet count and reduced thrombocrit. In premature newborns with a gestational age of 2527 weeks, blood circulation of platelets with a reduced volume was established, and in newborns who were born at a gestational age of 3234 weeks with increased granularity. In the absence of antenatal prevention of respiratory distress syndrome in newborns, there is a decrease in thrombocrit, the number of platelets, including large forms in the blood. In premature newborns born in a state of severe asphyxia, a decrease in platelet granularity was noted. The use of high concentrations of O2 in the oxygen-air mixture during respiratory therapy leads to a decrease in the number of platelets in the blood. Conclusions. Factors determining the morphofunctional state of platelets in premature newborns were established: the presence of a full course of antenatal prevention of respiratory distress syndrome of newborns, gestational age, the severity of asphyxia at birth, as well as the concentration of O2 in the oxygen-air mixture used in respiratory therapy. Newborns with ELBW have a reduced platelet count, low-granulated platelets, and an increased average dry platelet mass. Newborns with intrauterine growth retardation have a reduced number of platelets and thrombocrit in the blood. The revealed morphofunctional features of platelets allow us to clarify the nature of changes in the platelet link of hemostasis in premature newborns for the timely prevention of complications during the underlying disease.

To improve our understanding of the respiratory distress syndrome, the importance of early examination of the infant, preferably at delivery, cannot be overemphasized. An attempt should be made to estimate clinically the degree of birth asphyxiation by a method such as the Apgar Score. The nature of respirations as well as the rate should be noted, particularly retractions and grunting. Decreased response to stimuli or poor tone, and a low blood pressure are significant signs. In this review, a number of comparisons have been drawn, including evidence from adult medicine or animal experiments. While these may appear unrelated, irrelevant or unduly speculative, they have been introduced for several purposes: to draw attention to aspects of the syndrome other than respiratory distress; to acquaint the general reader with more recent physiology which is deemed pertinent; and to emphasize the importance of relating one system to another, especially respiration to circulation. Many of the studies of respiratory function point to cardiac as well as pulmonary failure, notably the need for oxygen in the presence of a normal tidal and increased minute volume. Other circumstantial evidence of cardiac failure is abundant. Asphyxia appears to play a central role, affecting almost every system in the body and every phase of metabolism. It is probably responsible for the normal or low venous pressures occurring with a failing myocardium. It also accounts for the higher incidence of respiratory distress in the smaller prematures who are unable to achieve and maintain normal lung expansion. The syndrome is uncommon in larger full-term infants and in these instances is associated with obstetrical complications causing more severe degrees of birth asphyxia. The clinical picture includes a number of variations depending upon whether respiratory depression or symptoms relating to the central nervous or gastrointestinal systems predominate. Nevertheless, diagnosis of the respiratory distress syndrome should rely not on the presence or absence of membranes at necropsy, but rather on the history, symptoms and clinical signs. Inasmuch as asphyxia is not a disease, it would seem more logical to regard the syndrome as a failure in adaptation to extrauterine life. Failure to comprehend the many adaptations which newborn infants must make, both cardiopulmonary and biochemical, together with a narrow view centering only around the hyaline membranes, have for so many years cloaked this syndrome with mystery. Physiologic measurements in sick infants are difficult, and many of the determinations and calculations arduous. Some of the studies require confirmation, and others remain to be done, employing new or improved technics which are free from disadvantages of older methods. Because of many variables, caution should be exercised in drawing conclusions from a small number of cases. Early pioneering work has contributed greatly and has paved the way for future investigations. The value of serial studies correlated with careful clinical observations in order that the precise nature of a dynamic process may be more fully revealed has been clearly shown.
