Evaluation of clinical outcomes of neonates born to mothers with coronavirus (COVID-19) in Shahid Beheshti Hospitals.

BACKGROUND: The coronavirus, which is caused by acute respiratory syndrome, appeared in Wuhan, China, in December 2019 and gradually spread around the world until almost all countries became infected with the coronavirus. In Iran, the outbreak of coronavirus began on February 21, 2020, with the report of infection of two people in the city of Qom. The aim of this study is to evaluate the clinical findings of neonates born to pregnant women with corona disease. MATERIALS AND METHODS: During this case study (February 21 to November 30, 2020), out of 88 pregnant mothers who referred to the hospitals of Shahid Beheshti University of Medical Sciences, 44 live neonates were born from 42 pregnant women with COVID-19, who were evaluated for clinical signs by studying their files and reported as a case series, due to limited samples, No statistical analysis of the study was performed. RESULTS: In studies of clinical records of hospitalized mothers and infants, among the polymerase chain reactions (PCRs) provided for all infants, one PCR was reported positive 2 days after birth, whereas this infant 10 min after birth, immediately after routine procedures, due to positive mother's PCR was isolated from the operating room. However, all of the infant's clinical symptoms were normal during the 3-day hospital stay for routine postpartum care. Twenty-eight days after birth, the baby was reevaluated for clinical, laboratory, and chest X-ray symptoms, all of which were normal. The PCR of other neonates was negative, and five intubated neonates, two twin, and two single died, and the other neonates were discharged. In evaluating the clinical records of mothers of these infants, the mean age is 30 years, and the average gestational age is 35 weeks, 32 cases of caesarean section, and 10 cases of normal delivery. CONCLUSION: We describe epidemiological data, demographics, signs and symptoms on admission, laboratory results, comorbidities, infection COVID-19 in the mothers and neonates, chest radiography and computed tomography findings, treatment received for COVID-19, and clinical maternal, fetal, and neonatal outcomes. Due to the fact that the study population is small consist of 42 mothers with COVID-19 infection, among all PCR samples from infants born to COVID-19 positive mothers, the PCR result of one case was positive, and the rest of was negative. Therefore, vertical transmission of COVID-19 through the placenta to the fetus cannot be confirmed or denied, nor can the COVID-19 confirmed or denied the baby's postnatal complication during pregnancy.

Predictors of Success Rate in Different Initial Respiratory Supports in Very Low Birthweight Infants with Respiratory Distress.

BACKGROUND: Ideal respiratory support for very low birth weight infants (VLBW) can be selected based on demographic and clinical status at birth. METHODS: In this prospective cohort study, we included 163 VLBW neonates treated with either invasive or non-invasive respiratory support in their first 72 hours of life in the neonatal intensive care unit of Mahdiyeh hospital, Tehran, Iran. We used descriptive statistics to describe the data, and multiple logistic regression to determine the factors associated with the success rate of different strategies and the choice of strategy for primary respiratory support. All analyses were done using SPSS version 20 and STATA version 12 at a significance level of 0.05. RESULTS: The success rates of initial respiratory supports with nasal continuous positive airway pressure (NCPAP), noninvasive positive pressure ventilation (NIPPV), and INSURE (intubation surfactant extubation) were 63.20%, 42.10% and 61.90%, respectively. The results of multiple logistic regression analysis showed patent arterial duct (PDA) (yes vs. no: OR = 0.42) had a significant effect on initial respiratory support success (P<0.05). Also, gestational age (>28 vs. ≤28 weeks: OR = 0.26) and 5-min APGAR (≤6 vs. >6: OR = 9.69) had a significant effect on the choice of initial respiratory support in VLBW infants (P<0.05). CONCLUSION: The neonatal clinical condition may be a predictor of success for initial respiratory support at birth. Since the arterial duct may be open during the first hours of life, more study is needed to verify if early closure of the arterial duct may help increase the success rate of non-invasive respiratory support.

Bilirubin Induced Encephalopathy.

Hyperbilirubinemia is one of the most common neonatal disorders. Delayed diagnosis and treatment of the pathologic and progressive indirect hyperbilirubinemia lead to neurological deficits, defined as bilirubin induced encephalopathy (BIE) (2). The incidence of this disorder in underdeveloped countries is much more than developed areas. All neonates with the risk factors for increased the blood level of indirect bilirubin are at risk for BIE, especially preterm neonates which are prone to low bilirubin kernicterus . BIE can be transient and acute (with early, intermediate and advanced phases)or be permanent, chronic and lifelong ( with tetrad of symptoms including visual (upward gaze palsy), auditory (sensory neural hearing loss), dental dysplasia abnormalities, and extrapyramidal disturbances (choreoathetosis cerebral palsy).Beside the abnormal neurologic manifestations of the jaundiced neonates ,brain MRI is the best imaging modality for the confirmation of the diagnosis. Although early treatment of extreme hyperbilirubinemia by phototherapy and exchange transfusion can prevent the BIE, unfortunately the chronic bilirubin encephalopathy does not have definitive treatment.

Incidence and risk factors of retinopathy of prematurity and utility of the national screening criteria in a tertiary center in Iran.

AIM: To determine the incidence and risk factors of retinopathy of prematurity (ROP) and the sensitivity of current screening criteria in a tertiary eye center in Tehran, Iran. METHODS: In a cross-sectional observational study, neonates weighing ≤2000 grams at birth or born <34wk gestational age (GA) and all other infants at risk of ROP admitted to the neonatal intensive care unit (NICU) or referred to our ROP clinic were investigated. The incidence of ROP and severe ROP (i.e. patients needing treatment) were determined. The associations between risk factors and the development and severity of ROP were assessed. We also examined the sensitivity of the current national screening guideline in Iran. RESULTS: Among 207 infants, the incidence of ROP and severe ROP was 33.3% and 11.1%, respectively. Mean GA and birth weight (BW) were significantly lower in ROP vs non-ROP infants (29±2wk vs 33±3wk, P<0.001; 1274±489 g vs 1916±550 g, P<0.001, respectively). Univariate analysis displayed significant association between ROP incidence and GA, BW, NICU admission period, blood transfusion, surfactant usage, sepsis, intraventricular hemorrhage and patent ductus arteriosus (P<0.05 for all). BW [relative risk (RR): 0.857 (0.711-0.873), P<0.001], GA [RR: 0.788 (0.711-0.873), P<0.001] and blood transfusion [RR: 1.888 (0.995-3.583), P=0.052] were independent ROP risk factors. The sensitivity of country-specific screening guidelines was 95.7% and 100% for overall and severe ROP detection, respectively. CONCLUSION: ROP incidence is relatively high in Iran. Identifying ROP risk factors results in more accurate screening and reduces the risk of irreversible vision loss. The ROP screening criteria utilized in Iran are efficient at the present time.

Meeting the Challenges of International Crises: The Experience of the Iranian Blood Transfusion Organization.

ABSTRACTCrises require a timely and well-prepared response by health services, especially those that are directly engaged with the lives of the patients such as blood services. The Iranian Blood Transfusion Organization as a single national authority of blood transfusion has left many crises behind. In this study, we examined the main international crises that the blood transfusion organization has faced during its 44-year history and objectively evaluated the methods for crisis risk reduction, both administrative and operational, all of which have led to fundamental advances in the organization. By proper planning and effective strategy setting, the Iranian Blood Transfusion Organization has managed to cope with international threats and in some cases has turned threats into opportunities to implement new, permanent administrative and operational strategies. It is not prudent for blood transfusion centers to develop their disaster risk reduction strategies on an individual-country basis in a world where global risk and crisis factors are rapidly increasing. Reduction of risk for blood transfusion centers must become a strategic priority nationally and globally. (Disaster Med Public Health Preparedness. 2019;13:410-413).

Incontinentia Pigmenti Misdiagnosed as Neonatal Herpes Simplex Virus Infection.

Incontinentia pigmenti (IP) is an X-linked dominant neurocutaneous syndrome with ophthalmologic, neurologic, cutaneous, and dental manifestations and in most cases antenatally lethal in boys. Occasionally, typical IP may occur in boys due to Klinefelter syndrome or a genomic mosaicism. Skin lesions are observed in 4 stages: blistering, verrucous linear plaques, swirling macular hyperpigmentation, followed by linear hypopigmentation that develop during adolescence and early adulthood. Neonatal herpes simplex virus (HSV) infection can be manifested in 3 forms: localized, disseminated, and central nervous system (CNS) involvement. Timely diagnosis and treatment of neonatal HSV infection is critical. In this case report, we present a 12-day female newborn with a history of maternal genital HSV in second trimester and vesicular lesions on the upper and lower limbs that was appeared at first hours of life. She was admitted in the maternity hospital that was born and was treated by antibiotic and acyclovir for 11 days. Then, she readmitted for her distributed vesicular lesions. The results of blood and CSF for HSV PCR were negative. Eventually the diagnosis for incontinentia pigmenti was made by consultation with a dermatologist, and skin biopsy confirmed the diagnosis.

Utilization of SNAP II and SNAPPE II Scores for Predicting the Mortality Rate Among a Cohort of Iranian Newborns.

BACKGROUND: The present study was conducted to determine the utility of Score for Neonatal Acute Physiology II (SNAP II) and Score for Neonatal Acute Physiology with Perinatal Extension II (SNAPPE II) scoring systems as predictors of neonatal mortality rate, and to compare the predictive value of these two methods. METHODS: In this prospective study data were gathered from infants admitted to the neonatal intensive care unit (NICU) of Imam Hossein Medical Center, Tehran, Iran, from March 2015 to December 2015. In addition to demographic data, Apgar score at 5 minutes after birth, initial and final diagnosis, SNAP II, and SNAPPE II were recorded within 24 hours after admission to the NICU. RESULTS: One hundred ninety-one newborn infants entered into the study. Birth weight (2555 ± 722 g in survival group versus 1588 ± 860 g in expired group, P<0.001), and Apgar score more than 7 at 5 minutes after birth (99.4% in survival group versus 57.1% in expired group, P<0.001) were significantly related to the mortality rate. By analyzing the data using logistic regression, it was found that SNAP II (area under the curve [AUC] = 0.992; 95% CI: 0.98-1) and SNAPPE II (AUC = 0.994; 95% CI: 0.984-1)had better value for predicting the patients' survival compared to Apgar score at 5 minutes after birth (AUC = 0.711; 95% CI: 0.568-0.855). There was no statistically significant difference in predictive value of SNAP II and SNAPPE II methods (P>0.99). CONCLUSION: According to our findings SNAP II and SNAPPE II are useful tools in predicting the mortality rate among Iranian neonates admitted to NICU. Although there was no significant difference between SNAP II and SNAPPE II, both methods had a much better predictive value compared to Apgar score at 5 minutes after birth.

Renal Hemosiderosis among Iranian Transfusion Dependent ß-Thalassemia Major Patients.

Background: In recent years, the success in management of thalassemic patients, has allowed for some previously unrecognized complications including renal abnormalities to emerge. This prospective study aimed to investigate kidney iron overload by means of MRI T2* and also renal function based on laboratory tests for early markers of glomerular and tubular dysfunction among adult Iranian transfusion-dependent thalassemia major patients. Subjects and Methods: Two-hundred and two patients with transfusion-dependent ß-thalassemia major were included in this study in Zafar Adult Thalassemia Center, Tehran, Iran. For all patients, kidney MRI T2* as well as evaluation of BUN, creatinine, uric acid, calcium, phosphorus, sodium (Na), potassium (K), total protein, albumin, cystatin C, serum ferritin ß2-microglobulin, NAG (N-acetyl-beta-D-Glucosaminidase), and urine protein were performed. Results: One-hundred and fourteen female and 88 male transfusion-dependent ß-thalassemia major patients with mean age of 30.1 ± 9.4 participated in the present study. We found that 77.7% of our patients had kidney hemosiderosis based on MRI T2*. Also, 67 patients (33.2%) had elevation of serum cystatin C, and 104 patients (51.5%) had reduced estimated glomerular filtration rate (e-GFR). Increased urinary excretion of NAG and hypercalciuria were found in 50% and 79.2% of participants, respectively. Conclusion: Renal hemosiderosis and asymptomatic renal dysfunction are prevalent among transfusion- dependent ß-thalassemia major patients which necessitate regular screening with early markers of glomerular and tubular dysfunction. Further studies in order to investigate the correlation between renal hemosiderosis and early markers of kidney dysfunction among these patients are recommended.

T2* Magnetic Resonance Imaging Study of Pancreatic Iron Overload and its Relation With the Diabetic State in Thalassemic Patients.

The present study was performed to evaluate pancreatic hemosiderosis by means of magnetic resonance imaging (MRI) T2* and its relation to the diabetic state in thalassemic patients. One hundred thirty transfusion-dependent thalassemic patients from Zafar adult thalassemia clinic, Tehran, Iran, were enrolled in the study. Data such as age, type of thalassemia, age at diagnosis, transfusion duration, ferritin level, and fasting blood sugar results were gathered. Pancreatic MRI T2* was performed for all patients. One hundred four thalassemic patients with no sign of diabetes mellitus and 26 thalassemic patients with diabetes mellitus entered the study. Out of a total of 130 patients, 102 had pancreatic hemosiderosis. Among them, 23 of 26 diabetic patients (88.5%) and 79 of 104 nondiabetic patients (76%) showed pancreatic hemosiderosis, indicating no statistically significant difference between the 2 groups. The mean pancreatic MRI T2* relaxation time for all patients was 13.99±12.43 ms. The mean relaxation was 13.62±8.38 and 14.08±13.28 ms for diabetic and nondiabetic patients, respectively, showing no statistical difference (P=0.202). In conclusion, we did not find a significant difference between diabetic and nondiabetic thalassemic patients regarding the MRI T2* relaxation time readings or the rate of pancreatic hemosiderosis. We recommend performing studies with a higher sample size and including patients from different age groups to further evaluate the role of T2* MRI of pancreatic iron overload and its relation with the diabetic state in thalassemic patients.

Transcutaneous Bilirubinometry in Preterm and Term Newborn Infants before and during Phototherapy.

INTRODUCTION: To evaluate the accuracy of transcutaneous bilirubin measurement in a large population of newborn infants, before and during the phototherapy. PATIENTS AND METHODS: A single Bilicheck instrument was used for transcutaneous measurements. A photo-opaque patch was positioned over the measurement site prior to starting phototherapy. Transcutaneous bilirubinometry was conducted on an unpatched area of the forehead skin and on the nearby site covered by the photo-opaque patch. Readings were obtained from patched and unpatched areas and simultaneous total serum bilirubin concentrations were compared. RESULTS: We studied 134 term and 36 preterm newborns. Pre-phototherapy measurements showed a strong correlation (r: 0.929, P < 0.001, Limit of agreement: -1.8 to 3.1) between Bilicheck and serum bilirubin readings. Post-phototherapy correlation between Bilicheck and serum bilirubin readings was (r: 0.921, P < 0.001, LOA: -1.8 to 2.8) among term and (r: 0.887, P = 0.001, LOA: -1.4 to 2.7) among preterm neonates in patched areas. These correlations were (r: 0.666, P < 0.001, LOA: -1.7 to 7.3) among term and (r: 0.756, P < 0.001, LOA: -0.5 to 5.3) preterm neonates post-phototherapy in unpatched areas. CONCLUSION: BiliCheck can be safely used for the evaluation of bilirubin levels in preterm and term newborn infants under phototherapy. BiliCheck is slightly less reliable among preterm newborns.

Effect of timing of umbilical cord clamp on newborns' iron status and its relation to delivery type.

OBJECTIVE: This study was conducted to evaluate the hematological effects of umbilical cord clamp timing and delivery type in term infants 48 hours after birth in Imam Hossein Hospital, Tehran, Iran. METHOD: From Oct 2007 - March 2008, 100 mother-infant eligible pairs were selected and divided by cord clamp timing (< or =15 s and >15 s) for hematologic value determination between the two groups. Data analysis was performed with SPSS for Windows statistical package (version 13). RESULTS: Maternal hematological status was assessed upon admission to the delivery room. A total of 100 mother-infant pairs were divided into two groups: delayed cord clamp time within 15 s (n=70) or early cord clamp time [15 s after delivery (n=30)]. The groups had similar demographic and biomedical characteristics at baseline. Forty-eight hours after delivery the mean infant hemoglobin (Hgb; 16.08 gm/dL vs. 14.5 gm/dL; P<0.001) and hematocrit (Hct 47.6 vs. 42.8; P<0.001) levels were significantly higher in the delayed clamping group. There was no significant difference in ferritin levels (214.7 vs. 173.6 ng/dL; P=0.08). Fifty infants were born vaginally and 50 were delivered by cesarean section. Infants delivered vaginally had significantly more delayed cord clamp times (>15 s; P<0.001). CONCLUSION: Delaying cord clamping increases the red cell mass in term infants. It is a safe, simple and low cost delivery procedure that should be incorporated in integrated programs that are aimed at reducing iron deficiency anemia in infants in developing countries. Vaginal delivery facilitates this action.
