Abstract
OBJECTIVES This study aimed to evaluate the results of congenital hypothyroidism screening (CHS) in neonates born to women with subclinical hypothyroidism (SHT) during pregnancy and to identify maternal and neonatal characteristics associated with recall rate in CHS. STUDY DESIGN This retrospective cohort study included nonrefugee pregnant women and newborn pairs who underwent thyroid function tests during prenatal follow-up between 2014 and 2017 and had neonatal CHS records. The women were evaluated overall and divided into euthyroidism (ET) and SHT groups according to their thyroid function tests. The groups were compared in terms of CHS results. Neonates with thyroid-stimulating hormone (TSH) levels <5.5 mIU/L were considered "normal," while those with values ≥5.5 mIU/L were "recall." RESULTS The antenatal thyroid function data of a total of 22,383 pregnant women were analyzed. Of these, 71.6% were ET and 16.3% were diagnosed as SHT. Overall, the recall rate accounted for 5.34% of all CHS results and the recall rate was higher in the SHT group (7.10%) compared with the ET group (5.54%; p = 0.001). Being low birth weight (LBW) or large for gestation age (LGA), maternal TSH above the 97.5th percentile, and cesarean delivery increased the risk of recall in CHS (p ˂ 0.05). CONCLUSION The recall rate was higher among the neonates of mothers with SHT. Being LBW or LGA, maternal TSH above the 97.5th percentile and cesarean delivery increased the risk of recall in CHS. KEY POINTS · SHT is the most common form of hypothyroidism in pregnancy.. · TSH elevation is higher among the neonates of mothers with SHT.. · Being LBW or LGA, and cesarean delivery also increase the risk of TSH elevation in infants..

Abstract
Background: Infants fed breast milk are known to have lower rates of childhood obesity. However, there is evidence suggesting an increased risk of obesity in infants who receive milk from a diabetic mother. The aim of this study was to investigate the calorie and macronutrient content of colostrum in mothers with gestational diabetes mellitus (GDM). Methods: This prospective, controlled study included mothers who had diagnosis of GDM and a control group of mothers without GDM who delivered at term. Colostrum samples were analyzed for macronutrients (fat, protein, and carbohydrate) and calorie content using a human milk analyzer (Miris, Uppsala, Sweden). Results: A total of 92 colostrum samples were analyzed, 31 in the GDM group and 61 in the non-GDM group. The carbohydrate content of colostrum in the GDM group was higher compared with the non-GDM group (p = 0.004). The calorie, fat, and protein contents of colostrum were similar between the groups (p > 0.05). Multiple regression analysis indicated that having GDM was significantly related to carbohydrate content. Conclusion: The colostrum of GDM mothers had higher carbohydrate content. This might be one of the factors explaining the relationship between diabetic breast milk and infantile obesity.

Abstract
OBJECTIVE This study aimed to compare the lung ultrasonography (LUS) scores after two different natural surfactant administration as a parameter reflecting lung inflation. STUDY DESIGN Preterm infants of 32 gestational weeks and below who were diagnosed with respiratory distress syndrome (RDS) were randomly assigned to be administered either poractant alfa or beractant, prospectively. Serial LUS scans were obtained by an experienced neonatologist in a standardized manner before and after (2 and 6 hours) surfactant administration. The LUS scans were evaluated by protocols based on scores and lung profiles. RESULTS Thirty-seven infants received poractant alfa and 36 received beractant. The baseline characteristics and presurfactant LUS scores were similar in groups. The scores were significantly decreased after surfactant administration in both groups (2 hours, p = < 0.001; 6 hours, p = < 0.001). LUS scores in poractant group were significantly lower than beractant group when compared at each time point. At the end of 6 hours, the number of infants with the normal profile was significantly higher in the poractant group (∼65%) than the beractant group (22%). CONCLUSION LUS is beneficial for evaluating lung aeration after surfactant treatment in preterm infants with RDS. A better lung aeration can be achieved in the early period with the use of poractant alfa.

Abstract
OBJECTIVE This study aimed to investigate the effect of delayed cord clamping (DCC) in infants of diabetic mothers. STUDY DESIGN Women who had diabetes throughout their pregnancy and gave birth at 37 weeks of gestation or later were included in the study along with their babies. Early cord clamping was performed as soon as possible after birth, while DCC was performed by clamping 60 second after birth. The two groups were compared in terms of venous hematocrit (htc) levels and rates of hypoglycemia, jaundice requiring phototherapy, and respiratory distress. RESULTS Venous htc levels at postnatal 6 and 24 hours were significantly higher in the DCC group (p = 0.0001). Polycythemia rates were higher in the DCC group at both 6 and 24 hours, but partial exchange transfusion (PET) was not needed in either group. There were no differences between the groups with regard to the rates of hypoglycemia or jaundice requiring phototherapy. Rate of admission to the neonatal intensive care unit (NICU) was lower in the DCC group. CONCLUSION Although DCC increased the rate of polycythemia, it did not result in PET requirement. Moreover, DCC reduced the severity of respiratory distress and the rate of admission to NICU due to respiratory distress.

Abstract
OBJECTIVE To investigate the effect of pretreatment with obestatin (OB), an endogenous hormone also found in mother's milk, in experimental necrotizing enterocolitis (NEC). STUDY DESIGN Pups were randomized into four groups: control, OB-control, NEC, and OB-NEC. NEC was induced by asphyxia and hypothermia in the NEC and OB-NEC groups. OB was administered to the OB-control and OB-NEC groups. Macroscopic scoring of the intestinal tract was evaluated and tissue samples were obtained for histopathological and biochemical examination on the fourth day. RESULTS OB improved the macroscopic appearance of the gut and the clinical score during the experiment (p < 0.05). The rate of occurrence of NEC in the OB-NEC group was lower than the NEC group (p = 0.001). OB prevented necrosis and reduced the number of apoptotic cells in the OB-NEC group compared with the NEC group (p = 0.006). Furthermore, interleukin-6 and malondialdehyde levels in the OB-NEC group were lower than the NEC group (p < 0.05). CONCLUSION OB reduced intestinal damage and prevented necrosis through anti-inflammatory and antiapoptotic effects in experimental NEC. This effect of OB should be confirmed in clinical studies. Furthermore, future research should investigate whether OB plays a role in NEC pathogenesis or NEC is associated with OB levels in the serum and in breast milk.

Abstract
OBJECTIVE Intraventricular hemorrhage (IVH) is an important problem in neonatal units not only in terms of its consequences but also its follow-up and the prediction of its emergence in newborns. In this study, we have compared platelet parameters such as platelet count (PC), mean platelet volume (MPV), and platelet mass index (PMI) in terms of IHV in very-low-birth-weight (VLBW) newborns. Thus, we have tried to determine platelet values to guide clinicians in both the prediction and follow-up of IVH. STUDY DESIGN This is a retrospective, multicenter, and case-controlled study. In this study, 386 cases of VLBW newborns (below 1,500 g) and gestational age below 32 weeks, hospitalized and monitored between August 8, 2012, and April 7, 2018, were included. The platelet values of the cases on their 12th hour postpartum (PC1, MPV1, and PMI1) and the platelet values on days 5 to 7 (PC2, MPV2, and PMI2) were recorded in their study cards. A p-value of <0.05 was accepted as statistically significant. RESULTS While there was no difference of PC1, MPV1, PMI1, PC2, or MPV2 values (p > 0.05), PMI2 values in the severe stage IVH group cases were found to be significantly lower compared with other platelet parameters (p < 0.05). CONCLUSION PMI2 values can provide clinicians with important knowledge that may aid them in recognizing important pathologies such as IVH.

Abstract
OBJECTIVES In addition to protecting cells against free radical harm thanks to its anti-oxidant nature, lycopene strengthens the bonds among cells and improves cell metabolism. This study focuses on analyzing therapeutic effects of lycopene in hyperoxia-induced neurodegenerative disorders in newborn rats. METHODS Term newborn rats were divided into four groups as the normoxia control group (group-1), normoxia+lycopene group (group-2), hyperoxia control group (group-3) and hyperoxia+lycopene group (group-4). Group-1 and group-2 were monitored in room air while the group-3 and group-4 were monitored at > 85% O2. The group-2 and group-4 were injected with lycopene intrapertioneally (i.p. ) at 50mg/kg/day while the other groups were injected with corn oil i.p. at the same volume. The rats we sacrificed on the 11th day following the 10-day hyperoxia. The brains were removed and oxidant system parameters were assessed. RESULTS Injury resulting from hyperoxia was detected in the white matter, cortical regions, and thalamus of the brains. It was observed that the number of apoptotic cells increased and the number of proliferating cell nuclear antigen (PCNA) positive cells decreased in the groups-3 and 4 compared to the group-1. No significant improvement in the number of apoptotic cells and PCNA positive cells was observed in the groups-3 and 4, and apoptosis increased as well. CONCLUSIONS This study found that lycopene, did not show any therapeutic effects for brain damage treatment in newborn rats. In addition, this study demonstrated that lycopene might lead to toxic effects.

Abstract
The aim of this study was to evaluate the therapeutic effect of lycopene on a hyperoxia-induced lung injury model in rat pups. Full-term rat pups were included in the study 12-24 h after delivery. The pups were separated into 4 groups: normoxia control (NC), hyperoxia control (HC), hyperoxia + lycopene (HL), and normoxia lycopene (NL). The normoxia groups were housed in ambient air, and the hyperoxia groups in > 85% O2. HL and NL groups received 50 mg lycopene in oil/kg body weight/day delivered intraperitoneally (i.p.), the other groups received oil alone. On day 11, the rat pups were sacrificed and their lungs removed. Statistically significant injury was observed in all histological parameters measured (MLI, proliferating cell nuclear antigen (PCNA), and apoptosis) in the HC group (HC vs NC, p = 0.001). This injury could not be reversed with lycopene treatment (HC vs HL, 0.05; NC vs HL, p = 0.001). With hyperoxia, statistically significant decreases were observed in biochemical parameters in terms of SOD, MDA, and IL-6 values (HC vs NC: SOD, p = 0.02; MDA, p = 0.043; IL-6, p = 0.001). The use of lycopene did not provide any improvement in these values (HC vs HL, p > 0.05). Hyperoxia or lycopene had no effect on IL-1β and GPx (p > 0.05). When comparing NC and NL groups, negative effects were observed in the group given lycopene in terms of MLI, PCNA, apoptosis, and IL-6 (all parameters, p = 0.001). We observed that 50 mg lycopene in oil/kg body weight/day given via i.p. had no curative effect on the hyperoxia-induced lung injury in newborn rats and may even induce adverse effects.

Abstract
Patients who have secondary pseudohypoaldosteronism (PHA) in addition to hyponatraemia, hyperpotassaemia and high serum aldosterone levels for the age were included in this retrospective study.Among eight patients, seven patients were diagnosed with PHA secondary to obstructive uropathy (OUP), whereas one patient had PHA secondary to ileostomy. Six patients with OUP had simultaneous urinary tract infection (UTI) and in all except one patient, secondary PHA recovered with only UTI treatment before applying surgical correction. All the patients were younger than 3 months age. In three patients with PUV diagnosis, salt wasting recurred in an UTI episode under 3 months of age.

Abstract
OBJECTIVE Cystatin C (CysC) is commonly used as a marker of renal failure in premature infants. The aim of this study was to investigate serum CysC levels in osteopenia of prematurity (OP) and determine whether CysC could be safely used as a marker of renal insufficiency in infants with OP. METHODS Subjects were 50 preterm infants (≤32 gestational weeks). Calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) serum levels were measured in postnatal week nine, and bone density was measured concurrently by quantitative ultrasonography. Patients with a Z score of <-2 were considered to have OP. RESULTS The mean serum CysC levels in preterm infants in postnatal week nine were 1.50±0.19 mg/L. Serum CysC levels were not correlated with speed of sound values, Z scores, serum Ca, P or ALP levels. Serum CysC levels were not significantly different between infants with OP [1.50 (1.35-1.61) mg/L] and in infants without OP [1.58 (1.28-1.70) mg/L]. CONCLUSION The presence of OP does not affect the safety of CysC as a marker of renal insufficiency in preterm infants.

Abstract
BACKGROUND Iodine deficiency (ID) during the fetal and neonatal periods can lead to neonatal hypothyroidism. This study was conducted to evaluate the effect of ID on the thyroid hormone level of newborns living in Turkey. METHODS Between 1998 and 2013, 71 newborns with a urinary iodine concentration <100 μg/L were recruited into the study. Data on thyroid volume, free triiodothyronine (fT3), free thyroxine (fT4), thyroid stimulating hormone (TSH), and thyroglobulin (Tg) were collected from all newborns, and on breast milk iodine from their mothers. Infants who were classified as having congenital hypothyroidism (TSH >40 mU/L and fT4 <8.5 pmol/L) were treated with levothyroxine (n=26, T group), while the remaining infants remained untreated (n=45, UT group). Thyroid hormones were subsequently measured 7-14 days later in a sub-sample of both treated and untreated infants. RESULTS The average values at the time of admission were as follows [median (min-max)]. fT3: 5.0 (2.8-7.1) pmol/L, fT4: 7.7 (0.13-19.1) pmol/L, TSH: 75 (14-426) mU/L, Tg: 464 (226-1100) ng/mL, urinary iodine concentration (UIC): 30 (0-61) μg/L, breast milk iodine levels: 21 (10-150) μg/L, thyroid ultrasound (USG): 1.10 (0.24-1.95) mL for the T group; and fT3: 5.7 (1.7-12.7) pmol/L, fT4: 16.2 (9.9-33.5) pmol/L, TSH: 5.4 (0.63-41.8) mU/L, Tg: 171 (15-2124) ng/mL, UIC: 39 (0-90) μg/L, breast milk iodine levels: 47 (10-120) μg/L, thyroid USG: 0.75 (0.35-1.72) mL for the UT group. A significant difference was found between groups in respect to fT3, fT4, TSH and Tg levels. No significant difference in thyroid ultrasonography, UIC, and breast milk iodine levels was found between the two groups. The Tg levels of 50 out of 71 patients were measured, 40 (80%) of whom had Tg levels above the normal range (101 ng/mL). CONCLUSIONS In our country, despite the use of iodized salt, congenital hypothyroidism due to ID remains a problem. The Tg level of newborns can be used as a good indicator of ID.

Abstract
OBJECTIVES To identify endocrinologic problems, particularly those concerning growth, in collodion babies (CBs). METHODS Clinically identified newborn CBs were included in the study group (group 1). Because CBs are generally born premature, small for gestational age (SGA), or both, a control group matched to the study group in terms of gestational age and birthweight (group 2) was also established. Blood specimens were collected from both groups for thyroid function tests and to measure serum growth hormone (GH), insulinlike growth factor 1 (IGF-1) and IGF binding protein-3 (IGFBP-3) levels. RESULTS Group 1 consisted of 42 CBs (25 male, 17 female) with gestational ages of 32 to 42 weeks and birthweights of 1,400 to 4,000 g. Twelve were assessed as premature and 17 as SGA. Serum IGF-1 and IGFBP-3 levels were lower and serum GH levels higher than in controls. Primary hypothyroidism was diagnosed in 10 patients in the study group, subclinical hypothyroidism in 2, and central hypothyroidism in 1. A statistically significant difference was determined between the groups in terms of primary hypothyroidism (p = 0.01). Serum GH levels were weakly negatively correlated with birthweight (correlation coefficient [r] = -0.32, p = 0.04) and serum IGF-1 (r = -0.38, p = 0.001) and IGFBP-3 (r = -0.36, p = 0.002) levels. CONCLUSION Premature birth and SGA are common in CBs. GH levels are high and IGF-1 and IGFBP-3 levels low at birth as a sign of GH resistance in these patients. The greater prevalence of hypothyroidism in these children is also significant.

Abstract
OBJECTIVES To assess whether TSH and fT4 have a role in the angiogenesis of vaso-obliteration and neovascularization which are the basic pathophysiology of ROP. METHODS In this retrospective case-control study, the control group (n = 56) included preterm newborns with risk for ROP while the laser group (n = 63) was recruited from cases who developed severe neovascularization and needed laser photocoagulation therapy. Considering the first (vaso-obliteration) and second (neovascularization) phases of the disease, in this study we researched the distribution of thyroid function tests between groups. RESULTS With regard to the first phase of the disease, TSH and fT4 showed no significant differences between the control and laser groups accordingly (P > 0.05). Likewise, in the second phase of ROP, there was no significant difference between the control and laser groups with respect to TSH and fT4 levels (P > 0.05). CONCLUSION We found that between the study groups, the levels of thyroid function tests did not have any significant differences, either in the first or the second phases of ROP which are the principal pathophysiology of the disease. Therefore, it was concluded that thyroid hormone values were not informative markers in the course of the disease in preterm babies at risk of developing ROP.

Abstract
Branding refers to a traditional practice of creating 'therapeutic' burns with hot iron rods over the skin in order to treat various diseases. Although branding is a harmful practice for the body, it has been used for various illnesses including physiologic jaundice in newborns, pneumonia, and convulsions. It causes serious morbidity and delays seeking proper medical care in neonates. Innovations of modern medicine and the use of evidence-based medicine should be preferred instead of these traditional practices. We present a branded mature newborn baby who was diagnosed as having adrenocorticotropic hormone resistance syndrome. This problem is very rare in Turkey; however, it is a very important health issue and has social aspects. Therefore, this case is presented to increase awareness.

Abstract
Contiguous gene deletions of chromosome Xp21 can lead to glycerol kinase deficiency and severe adrenocortical insufficiency (AI) in a male newborn among other problems. We describe our experience with two such patients who presented with dysmorphic facies, AI, and pseudo-hypertriglyceridemia. Both infants had normal serum 17-hidroxyprogesterone levels, and adrenal glands could not be observed with ultrasonography. Creatine kinase and triglyceride levels were measured to elucidate the etiology of adrenal hypoplasia and were above normal limits in both cases. Both patients required steroid and salt supplementation. They were both found to have Xp21.2 deletions (DMD, NR0B1, GK, IL1RAPL1). We conclude that AI in the context of other genetic abnormalities should prompt chromosomal investigations in the absence of another unifying explanation.

Abstract
In spite of advances in neonatal care and the new generation of antibiotics, neonatal sepsis is still a major cause of morbidity and mortality. Early diagnosis of neonatal sepsis is difficult because clinical signs are non-specific. Thus, new biomarkers are still needed for diagnosis. Gelsolin is an actin-binding plasma protein. Furthermore, extracellular gelsolin binds lipopolysaccharide and lipoteichoic acid, which are major virulence factors of Gram-negative and Gram-positive bacteria. The result of this binding is the inhibition of gelsolin's F-actin depolymerizing activity. Thus, gelsolin inhibits the release of IL-8 from human neutrophils subjected to lipoteichoic acid, lipopolysaccharide and heat-inactivated bacteria treatment. Our hypothesis is that pGSN levels decrease in neonatal infants with sepsis and this decrease might be used as a reliable biological marker. Forty patients who were diagnosed with severe sepsis at a neonatal intensive care unit were enrolled in the sepsis group. Twenty patients who were followed for prematurity were enrolled in the control group. The pGSN level at the time of diagnosis in the sepsis group was 33.98±11.44μg/ml, which was significantly lower than that of control group (60.05±11.3μg/ml, P<0.001) and after treatment (53.38±31.26μg/ml, P=0.003). Area under ROC curve was 0.96 (p: 0.0001, 95% CI; 0.90-0.99). Sensitivity was 90.32 (95% CI; 74.2-97.8), specificity was 95 (95% CI; 75.1-99.2). Plasma gelsolin significantly decreased in septic patient and recovery of decreased gelsolin levels correlated with clinical improvement. Thus, plasma gelsolin may be a usable marker for severe sepsis.

Abstract
PURPOSE Retinopathy of Prematurity (ROP) is a proliferative vitreoretinopathy which is one of the most frequent causes of blindness in children. In an attempt to find a solution to this important problem in preterm children, the search for new, effective treatment modalities with fewer side effects is underway. In our study, which was planned for this reason, we aimed to investigate the effects of propranolol treatment applied to cases of ROP in various stages during the second phase (known as the neovascularization-hypoxia phase) and to determine the correlation of these effects with the platelet mass index (PMI). METHOD A total of 171 preterm infants at risk of ROP were selected randomly for inclusion in the study. All of the patients were classified according to their stage of ROP and were divided into control and treatment groups. While the cases in the control group were administered physiological saline solution, those in the treatment group were administered propranolol in the period that corresponded to the second stage of the disease. The thrombocyte and PMI values in the first and second stages of each study group were recorded. RESULTS A significant difference was found between the control and treatment groups of the stage 2 ROP study subjects. In the stage 2 ROP study group, no significant difference was detected between the control and treatment cases in terms of platelet counts in phase 1 or in the PMI values and the thrombolytic counts in phase 2. On the other hand, in phase 2 of the stage 2 ROP study subjects significant differences were detected between the control and treatment group in terms of PMI values. CONCLUSION In the study, it was found in the stage 2 ROP study group that propranolol reduced the need for laser photocoagulation significantly. Also, in parallel to the efficacy of propranolol in this study group, a decrease was observed in PMI values.

Abstract
Hair-thread tourniquet syndrome is a rare disorder characterized by the encircling of an appendage by a hair or thread. It usually occurs in children under the age of one year. The tourniquet syndrome may occur in different parts of the body, particularly in toes, fingers, penis, clitoris, labia, neck and uvula. It is an emergency condition that induces progressive edema, ischaemia and tissue necrosis and can lead to autoamputation of digits or other strangulated structures. Emergency treatment is careful removal of the constricting fiber. We report a preterm newborn with hair-thread tourniquet syndrome affecting multiple toes born at the 28th gestational week with the aim of preventing potential complications by increasesing awareness of the condition.

Abstract
Early onset Marfan Syndrome (eoMFS) is a rare, severe form of Marfan Syndrome (MFS). The disease has a poor prognosis and most patients present with resistance to heart failure treatment during the newborn period. This report presents two cases of eoMFS with similar clinical features diagnosed in the newborn period and who died at an early age due to the complications related to the involvement of the cardiovascular system.

Abstract
Pseudohypoaldosteronism (PHA) is defined as a state of resistance to aldosterone, a hormone crucial for electrolyte equilibrium. The genetically transmitted type of PHA is primary hypoaldosteronism. Secondary hypoaldosteronism develops as a result of hydronephrosis or hydroureter. PHA patients suffer from severe hyponatremia and a severe clinical condition due to severe loss of salt can be encountered in the neonatal period. Dermal findings in the form of miliaria rubra can also develop in these patients. With the loss of salt, abnormal accumulation of sebum in the eye due to a defect in the sodium channels can also occur. In this paper, a case of PHA in a newborn showing typical dermatological and ophthalmological findings is presented.

Abstract
Hydatid cyst, a common disease in the world, is usually transmitted to humans through dog feces. Hydatid cyst is caused by Echinococcus granulosus. Diagnostic interventions for hydatid cyst include physical examination and chest x-ray tomography. Although the treatment options of hydatid cyst vary according to the clinical findings of the patients, the primary treatment may be considered as surgery. We herein reported the case of a child hospitalized due to pneumonia who developed anaphylaxis as a result of the rupture of a pulmonary hydatid cyst.

Abstract
INTRODUCTION Excessive iodine exposure during the fetal and neonatal periods can lead to neonatal hypothyroidism. This study was conducted to evaluate the level of iodine loading among newborns living in Kayseri province. A total of 59 newborns, who were admitted due to disorders in thyroid hormone levels, were included in the study. Materials and METHODS Among the patients who applied with thyroid hormone dysfunction, newborns with a spot urine iodine level ≥ 20 μg/dL were included in the study between the years 2003 and 2013. Free T3 (fT3), free T4 (fT4), thyroid stimulating hormone (TSH), thyroglobulin (Tg), breast milk iodine, thyroid ultrasonography, and control measurements of fT3, fT4, TSH, and Tg levels were obtained accordingly from both groups of patients who received or did not receive treatment. RESULTS The average age of the patients was 15 days with a 36/23 girl to boy ratio. Statistically, no significant difference was noticed between all the girls and boys with respect to all the measured values. The etiologic search showed that out of 59 cases, in 18 cases (30.5%) only the mother and in 19 cases only the newborns (32.2%) had a history of povidone iodine exposure; in 8 cases both mothers and their babies had exposure to povidone iodine (13.6%). In 14 cases (23.7%), the source of iodine loading could not be determined. Levothyroxine (L-thyroxine) treatment was initiated in 56% of the patients (n = 33). Out of 33 patients who were under treatment with L-thyroxine, in 13 cases only the mother had history of povidone iodine exposure; in 12 cases, only the baby had a history of povidone iodine exposure; in 1 case, both mother and her baby had a history of povidone iodine exposure, but the etiology could not be found in 7 cases. CONCLUSION The use of antiseptics-containing iodine for mothers before and after birth and for newborns, especially for umbilical cleansing, can lead to iodine loading and hypothyroidism. If transient hypothyroidism develops within this period, then it may not be detected promptly. This can later lead to retardation in psychomotor development and disorder in learning skills during the childhood period.
