Management of twin reversed arterial perfusion sequence: eight cases over 13 years.

BACKGROUND: Twin reversed arterial perfusion (TRAP) sequence is a rare condition that affects primarily monozygotic monochorionic twin pregnancies in which a normal twin acts as a pump (donor) for an acardiac recipient (perfuse) twin. OBJECTIVE: We report our experience over the last 13 years at a tertiary health care center. DESIGN: Descriptive, retrospective case series SETTING: Tertiary health care center PATIENTS AND METHODS: All TRAP cases managed between the years 2009 and 2022 at our Fetal Diagnosis and Therapy Center were included. Data recorded included demographic and clinical information which was used to generate descriptive data. Patients were managed by a multidisciplinary team with variable interventions. MAIN OUTCOME MEASURE: Survival of normal twin SAMPLE SIZE: Eight RESULTS: Eight pregnant women with TRAP syndrome were managed at our center during that period. One was monozygotic monochorionic and the others were monochorionic diamniotic. Median maternal age at presentation was 27 years and median gestational age at diagnosis was 23 weeks. All were diagnosed with ultrasound (US) imaging. Three were managed with bipolar ligation of the cord of the acardiac twin under general anesthesia, one US-guided (single port) and 2 fetoscopic (2 ports) with a median operative time of 39 minutes. The last five cases were managed with US-guided radiofrequency ablation (RFA) under local anesthesia, one needed 2 sessions, 1 week apart. The median duration of the RFA procedure was 23 minutes. There were no complications and all had viable normal babies born at a median of 32 weeks of gestation (6 C-section, 2 spontaneous membrane rupture). CONCLUSIONS: Acardiac twin cord ligation and RFA are feasible and safe options with excellent outcome for TRAP syndrome. RFA may be preferable owing to its less invasiveness under local anesthesia. LIMITATIONS: None, given the rarity of the disease and the study design. CONFLICT OF INTEREST: None.

Significance of Intermittent Hypoxic Episodes in Premature Infants Prior to Discharge.

Objective The aim of this study was to determine the rate and severity of intermittent hypoxic episodes in premature infants who underwent overnight pulse oximetry prior to discharge. Methods Preterm infants with a birth weight of 1500 grams or less and who underwent overnight pulse oximetry prior to discharge were included. Maternal and neonatal demographic data and complications of prematurity were recorded. All infants underwent overnight pulse oximetry prior to discharge and the McGill score was used to categorize the degree of desaturations (categories 1-4; normal, mildly, moderately, and severely abnormal). Results Fifty infants underwent the overnight pulse oximetry The McGill score showed that 2% had no hypoxia, 50% had mild hypoxia, 20% had moderate hypoxia, and 28% had severe hypoxia. The frequency of desaturations (62.5%) was found more in infants with a birth weight of 1000 grams or less. The results showed that the O2 requirement at discharge was significant (p = 0.0341), and increased values of O2 at discharge were associated with more severe hypoxia. As a result of these findings, 40% of infants were discharged home on oxygen and 26% were discharged on caffeine. Fifty-two percent of infants were initially diagnosed to have stages 1 & 2 retinopathy of prematurity (ROP), 14% had stage 3, and 2% had stage 4 ROP. Eight percent of infants required surgical intervention for ROP. Conclusions Clinically inapparent significant episodes of intermittent hypoxia (IH) are frequent in preterm infants in the early postnatal age, and they may persist post-discharge. Knowledge of the association between IH and morbidity among all neonatal intensive care unit (NICU) caregivers would be of great benefit. Indications for screening preterm infants at risk of severe IH should be reconsidered.

Fetal malformations associated with exposure to mycophenolic acid during the first trimester.

Mycophenolic acid [MPA] is a powerful inhibitor of lymphocyte proliferation. Although this drug has been used across the globe for various maternal comorbidities, multiple concerns have been raised regarding its teratogenic effects. The Food and Drug Administration has changed its category to drug category D (evidence of fetal risk) in 2007. A wide range of congenital malformations in infants born to a mother using this medication have been described in the literature, but there is no specific set pattern of these malformations. We report a case of a female infant who had exposure to mycophenolate by maternal use during the initial phase of 1st trimester of her pregnancy and ended up having multiple congenital malformations. She was managed with multidisciplinary approach and was finally discharged home on respiratory support, after two months of hospital stay. The fact that our patient shared a pattern of congenital malformations with other reported cases who were exposed to mycophenolate in utero strongly suggests that mycophenolate had a causal role and that there might be an emerging fetal mycophenolate mofetil syndrome (FMMS).

Effects of Probiotics and Lactoferrin on Necrotizing Enterocolitis in Preterm Infants.

Background Necrotizing enterocolitis (NEC) is a leading cause of morbidity and mortality in neonates. Despite intensive research, the etiology and pathophysiology of NEC is still obscure. Evidence from recent studies and meta-analyses showed a significant role of probiotics as a prophylactic measure in reducing NEC, sepsis, and mortality. However, obstacles against the generalization of the results still remain. The aim of the study was to evaluate the role of prophylactic administration of probiotics and lactoferrin in reducing the rate of NEC in preterm infants. Methods In this retrospective cohort study, all medical records of infants born with a birth weight of 1,500 g and less who were born between 2012 and 2017 were reviewed. The enrolled infants were divided into two groups: group 1 included infants born between January 2012 and August 2014, a period before probiotics were started in our unit, and group 2 included infants born between January 2014 and December 2017 after starting probiotics and lactoferrin. Multiple variables were collected including maternal data, neonatal data, and risk factors for NEC. Results Medical records of 284 infants who met our inclusion criteria were reviewed. Of the 284 infants, 134 were in group 1 and 150 infants were in group 2. There were no significant statistical differences between group 1 and group 2 in neonatal and maternal demographic data and clinical data. Of 134 infants who received probiotics and lactoferrin, 11 developed NEC, while 26 of the 150 infants in group 2 developed NEC, and the difference was statistically significant (p = 0.023). Conclusion Probiotics and lactoferrin given orally to very low birth weight preterm infants were associated with a decreased rate of NEC.

Decisions and outcome for infants born near the limit of viability.

BACKGROUND: Initiation or withholding life support at birth on infants born prematurely near the limit of viability is not an easy decision, with wide variation in practice around the world. Our aim was to review the outcome of preterm infants born near the limit of viability at 23-25 weeks gestation in our institution, with regard to resuscitation decision, survival, and major outcome measures. METHODS: We included all live newborn infants born prematurely at 23-25 weeks gestation at King Faisal Specialist Hospital and Research Centre from January 2006 to December 2015. We collected data on resuscitation decisions, survival, and major neonatal morbidities such as severe brain injury, severe retinopathy of prematurity, and bronchopulmonary dysplasia. RESULTS: Between January 1, 2006 and December 31, 2015, 97 infants with a gestational age (GA) of 23-25 weeks gestation were admitted; 23, 42, and 32 infants were born at 23, 24, and 25 weeks gestation, respectively. At 23 weeks gestation, full support was initiated in 87% of patients and later on support was withheld in 17.4% of patients, finally 13% of patients survived to discharge. At 24 weeks, full support was initiated in 97.6% of patients, then withheld in 7.1% of patients, and ultimately 59.5% survived. At 25 weeks, full support was initiated in 93.8% of patients, then withheld in 15.6% of patients, and ultimately 62.5% survived. In terms of survival with and without the three major neonatal morbidities, at 23 weeks gestation, no infant survived without any morbidity as compared to 7.1% and 28.1% at 24 and 25 weeks, respectively. The incidence of survival with 1 major morbidity was 8.7%, 30.9%, and 34.4% at 23, 24, and 25 weeks, respectively, the incidence of survival with 2 major morbidities was 0%, 19%, and 0% at 23, 24, and 25 weeks, respectively, and the incidence of survival with 3 major morbidities was 4.3%, 2.4%, and 0% at 23, 24, and 25 weeks, respectively. CONCLUSION: In our patient cohort, survival and survival without major neonatal morbidity were very low at 23 weeks gestation, but it improved gradually as gestational age advanced.

Short-term outcome of very low-birth-weight infants in a tertiary care hospital in Saudi Arabia.

BACKGROUND AND OBJECTIVE: Published data on short-term outcomes of very low birth weight infants from Saudi Arabia are limited. In the present study, our objective was to describe and analyze the outcomes of very low birth weight infants admitted to our neonatal intensive care unit and to compare the results with data published by the National Institute of Child Health and Development. DESIGN AND SETTING: This study was a retrospective analysis of prospectively collected data from a single tertiary care center over a three years period. PATIENTS AND METHODS: Biodemographic data and data regarding multiple outcome measures were analyzed for infants with birth weight of 1500 g or less. Data were obtained from our neonatal intensive care unit database. RESULTS: Our results included a total of 186 infants with birth weights of 1500 g or less. Of these infants, 154 (82.8%) survived to discharge. Seventy-six (40.9%) were male, and mean (SD) gestational age (GA) was 29 (2.9) weeks with a range of 21 weeks, 6 days to 36 weeks, 2 days. Mean (SD) birth weight was 1062 (302) g with a range of 420 to 1495 g. Fifty-seven (30.6%) infants were characterized as small for gestational age. Antenatal steroids were given to 74.2% of mothers. Eighty-five percent of infants were born by cesarean section. The rate of bronchopulmonary dysplasia was 17.7%, patent ductus arteriosus 31.2%, intraventricular hemorrhage 12.9%, periventricular leukomalacia 3.8%, necrotizing enterocolitis 7.5%, retinopathy of prematurity 28.3%, and late-onset sepsis was 21.9%. CONCLUSION: In this population of very low birth weight infants, survival rates and complications of prematurity were comparable to international data.

The need for hospital-based neonatal palliative care programs in Saudi Arabia.

The terms palliative care, supportive care, and comfort care are used to describe individualized care that can provide a dying person the best quality of life until the end. The term "end-of-life care" is also used in a general sense to refer to all aspects of care of a patient with a potentially fatal condition. While the concept of palliative care is not new, it has only recently been applied to the neonatal population. To the best of our knowledge, none of the neonatal intensive care units (NICUs) in Saudi Arabia have adopted a neonatal program for palliative care. We believe the main reason is lack of knowledge of such programs and the fear of being accused of being heartless and cruel by providing comfort care for dying babies. Comfort care begins with the diagnosis of a life-threatening/terminal condition, and continues throughout the course of illness regardless of the outcome. In this perspective, our aim is to introduce these programs for caregivers in the NICUs in Saudi Arabia. For this purpose, we have reviewed the current recommendations in establishing neonatal palliative care programs and discussed some of the social and religious aspects pertaining to this issue.
