Early neonatal outcomes in infants of mothers with organ transplantation under immunosuppressive treatment.

BACKGROUND: This study aimed to examine early clinical and laboratory findings in infants born to mothers who had organ transplants and received immunosuppressive treatment. METHODS: Between 2016 and 2023, the study examined infants of mothers who underwent organ transplantation and were receiving immunosuppressive treatment, and followed at the Department of Neonatology at Akdeniz University. Demographic, clinical, and laboratory characteristics of mothers and infants were recorded. On the first day of life, complete blood count values were examined, as well as potassium levels on the first, third, and seventh days, and creatinine levels on the third and seventh days. The tacrolimus blood level was calculated by taking the average of the tacrolimus blood values of the mother measured during the pregnancy. The infants were evaluated for any potential morbidities caused by intrauterine immunosuppressive drug exposure. RESULTS: The study included 21 mothers (some with multiple pregnancies) and 27 infants. According to the findings of this study, 74% of these infants were born premature, 67% had low birth weight, and all were delivered via cesarean section. Prematurity was associated with the morbidities found in the infants. In the early period, lymphopenia was detected in 37%, neutropenia in 25.9%, thrombocytopenia in 11.1%, hyperkalemia in 18.5%, and creatinine elevation in 7.4%, all of which returned to normal within a few days. There was no significant relationship between maternal tacrolimus blood levels and infant potassium and creatinine levels. CONCLUSION: Apart from an increased risk of prematurity, low birth weight, and cesarean delivery, no effects were observed in these infants during the early period. However, long-term follow-up is necessary to monitor for any potential morbidities.

Miracles of science: Birth after uterus transplantation.

AIM: The concept of regaining childbearing ability via uterus transplantation (UTx) motivates many infertile women to pursue giving birth to their own children. This article provides insight into maternal and neonatal outcomes of the procedure globally and facilitates quality of care in related medical fields. METHODS: The authors searched ISI Web of Science, MEDLINE, non-PubMed-indexed journals, and common search engines to identify peer-review publications and unpublished sources in scientific reference databases. RESULTS: The feasibility of the procedure has been proven with 46 healthy children in 88 procedures so far. Success relies upon dedicated teamwork involving transplantation surgery, obstetrics and reproductive medicine, neonatology, pediatrics, psychology, and bioethics. However, challenges exist owing to donor, recipient, and fetus. Fetal growth in genetically foreign uterine allograft with altered feto-maternal interface and vascular anatomy, immunosuppressive exposure, lack of graft innervation leading to "unable-to-feel" uterine contractions and conception via assisted reproductive technology create notable risks during pregnancy. Significant portion of women are complicated by at least one or more obstetric problems. Preeclampsia, gestational hypertension and diabetes mellitus, elevated kidney indices, and preterm delivery are common complications. CONCLUSIONS: UTx has short- and long-term satisfying outcome. Advancements in the post-transplant management would undoubtedly lead this experimental procedure into mainstream clinical practice in the near future. However, both women and children of UTx need special consideration due to prematurity-related neonatal problems and the long-term effects of transplant pregnancy. Notable health risks for the recipient and fetus should be discussed with potential candidates for UTx.

An observational, multicenter, registry-based cohort study of Turkish Neonatal Society in neonates with Hypoxic ischemic encephalopathy.

BACKGROUND: Hypoxic ischemic encephalopathy (HIE) is a significant cause of mortality and short- and long-term morbidities. Therapeutic hypothermia (TH) has been shown to be the standard care for HIE of infants ≥36 weeks gestational age (GA), as it has been demonstrated to reduce the rates of mortality, and adverse neurodevelopmental outcomes. This study aims to determine the incidence of HIE in our country, to assess the TH management in infants with HIE, and present short-term outcomes of these infants. METHODS: The Turkish Hypoxic Ischemic Encephalopathy Online Registry database was established for this multicenter, prospective, observational, nationally-based cohort study to evaluate the data of infants born at ≥34 weeks GA who displayed evidence of neonatal encephalopathy (NE) between March, 2020 and April 2022. RESULTS: The incidence of HIE among infants born at ≥36 weeks GA (n = 965) was 2.13 per 1000 live births (517:242440), and accounting for 1.55% (965:62062) of all neonatal intensive care unit admissions. The rates of mild, moderate and severe HIE were 25.5% (n = 246), 58.9% (n = 568), and 15.6% (n = 151), respectively. Infants with severe HIE had higher rates of abnormal magnetic resonance imaging (MRI) findings, and mortality (p<0.001). No significant difference in mortality and abnormal MRI results was found according to the time of TH initiation (<3 h, 3-6 h and >6 h) (p>0.05). TH was administered to 85 (34.5%) infants with mild HIE, and of those born of 34-35 weeks of GA, 67.4% (n = 31) received TH. A total of 58 (6%) deaths were reported with a higher mortality rate in infants born at 34-35 weeks of GA (OR 3.941, 95% Cl 1.446-10.7422, p = 0.007). CONCLUSION: The incidence of HIE remained similar over time with a reduction in mortality rate. The timing of TH initiation, whether <3 or 3-6 h, did not result in lower occurrences of brain lesions on MRI or mortality. An increasing number of infants with mild HIE and late preterm infants with HIE are receiving TH; however, the indications for TH require further clarification. Longer follow-up studies are necessary for this vulnerable population.

Evaluation and management of neonatal onset hyperinsulinemic hypoglycemia: a single neonatal center experience.

OBJECTIVES: To evaluate the clinical characteristics and treatment options of neonates requiring prolonged hospitalization due to persistent hyperinsulinemic hypoglycemia (HH). METHODS: This retrospective cohort study included infants >34 weeks of gestation at birth who were born in our hospital between 2018 and 2021, diagnosed with HH, and required diazoxide within the first 28 days of life. The baseline clinical characteristics, age at the time of diagnosis and treatment options in diazoxide resistance cases were recorded. Genetic mutation analysis, if performed, was also included. RESULTS: A total of 32 infants diagnosed with neonatal HH were followed up. Among the cohort, 25 infants were classified as having transient form of HH and seven infants were classified as having congenital hyperinsulinemic hypoglycemia (CHI). Thirty-one percent of the infants had no risk factors. The median birth weight was significantly higher in the CHI group, whereas no differences were found in other baseline characteristics. Patients diagnosed with CHI required higher glucose infusion rate, higher doses, and longer duration of diazoxide treatment than those in the transient HH group. Eight patients were resistant to diazoxide, and six of them required treatment with octreotide and finally sirolimus. Sirolimus prevented the need of pancreatectomy in five of six patients without causing major side effects. Homozygous mutations in the ABCC8 gene were found in four patients with CHI. CONCLUSIONS: The risk of persistent neonatal hyperinsulinism should be considered in hypoglycemic neonates particularly located in regions with high rates of consanguinity. Our study demonstrated sirolimus as an effective treatment option in avoiding pancreatectomy in severe cases.

Neonatal Resuscitation Practices in Turkey: A Survey of the Turkish Neonatal Society and the Union of European Neonatal and Perinatal Societies.

OBJECTIVE: Optimal care in the delivery room is important to decrease neonatal morbidity and mortality. We aimed to evaluate neonatal resuscitation practices in Turkish centers. MATERIALS AND METHODS: A cross-sectional survey consisted of a 91-item questionnaire focused on delivery room practices in neonatal resuscitation and was sent to 50 Turkish centers. Hospitals with <2500 and those with ≥2500 births/year were compared. RESULTS: In 2018, approximately 240 000 births occurred at participating hospitals with a median of 2630 births/year. Participating hospitals were able to provide nasal continuous-positiveairway-pressure/high-flow nasal cannula, mechanical ventilation, high-frequency oscillatory ventilation, inhaled nitric oxide, and therapeutic hypothermia similarly. Antenatal counseling was routinely performed on parents at 56% of all centers. A resuscitation team was present at 72% of deliveries. Umbilical cord management for both term and preterm infants was similar between centers. The rate of delayed cord clamping was approximately 60% in term and late preterm infants. Thermal management for preterm infants (<32 weeks) was similar. Hospitals had appropriate equipment with similar rates of interventions and management, except conti nuous-positive-airway-pressure and positive-end-expiratory-pressure levels (cmH2O) used in preterm infants (P = .021, and P = .032). Ethical and educational aspects were also similar. CONCLUSIONS: This survey provided information on neonatal resuscitation practices in a sample of hospitals from all regions of Turkey and allowed us to see weaknesses in some fields. Although adherence to the guidelines was high among centers, further implementations are required in the areas of antenatal counseling, cord management, and circulation assessment in the delivery room.

Specific Granule Deficiency Due To Novel Homozygote SMARCD2 Variant.

Background: Specific granule deficiency (SGD) is a rare immunodeficiency associated with CCAT/enhancer-binding protein epsilon (CEBPE) gene variants. It can cause severe recurrent infections and is lethal without successful stem cell transplantation. Few cases with SGD of both type 1 and type 2 have been described in the literature. In this study, we present the first report of a case with a novel homozygous c.511 C > T (p.Gln171Ter) mutation in the SMARCD2 gene of SGD type 2, which was successfully treated with bone marrow transplantation. Case: A male infant presented to our neonatal intensive care unit on the second day of life with an icteric appearance and mild hypotonia. He was evaluated for immunodeficiency as the cause of delayed cord separation and refractory neutropenia. At 6 weeks of age, SGD type 2 with a new variant was diagnosed and successfully treated by bone marrow transplantation. Conclusion: SGD is an immunodeficiency disease that is quite rare. However, we believe that SGD diagnosis and associated new variants can be detected more frequently with the widespread use of all whole-exome sequencing techniques.

Birth of a Healthy Baby 9 Years After a Surgically Successful Deceased Donor Uterus Transplant.

OBJECTIVE: To describe surgical procedures, previous failed pregnancies, methods for overcoming pregnancy failure and, most importantly, birth of a healthy infant, in a uterus transplantation from a deceased donor. BACKGROUND: Majority of uterus transplants have involved live donors, but several advantages make deceased donor transplantation a practicable option, principally by eliminating surgical risks to the live donor. METHODS: Uterus transplantation from a deceased donor was performed in September 2011 in Turkey. After 5 miscarriages, perfusion computed tomography revealed an obstructed blood-outflow. To overcome this blood flow obstruction, a saphenous vein graft was anastomosed between utero-ovarian and left ovarian vein with laparotomy. Follow-up computed tomography confirmed resolution of venous congestion and a decrease in uterine volume. RESULTS: Following vascular augmentation surgery, fetal cardiac activity were observed 28 days after the first embryo transfer attempt. Preterm premature rupture of the membranes was diagnosed at 19 weeks' gestation. Cesarean section was planned at 28 weeks' gestation due to intrauterine growth restriction and suspected preeclampsia. A healthy 760 g male baby was delivered. The baby was discharged from the neonatal intensive care unit 79 days after delivery in good condition weighing 2475 g. CONCLUSIONS: Deceased donor uterus transplantation is a reasonable approach for treating uterine factor-related infertility. In case of recurrent miscarriages, regional vascular augmentation by arterial or venous supercharging may be required to overcome regional misperfused regions determined by imaging studies.

Hypernatremic Dehydration Risk Factors in Newborns: Prospective Case-Controlled Study.

BACKGROUND: The prevalence of hypernatremic dehydration (HND) has increased in recent years most likely due to insufficient intake of breast milk as the most important factor. This study aimed to investigate risk factors of HND. METHODS: In this study, 47 neonates whom were diagnosed to have HND were included in the study group and 96 healty neonates whom were included in the control group. While demographic data of the patients were recorded, mothers were asked to fill out the sociodemographic/ psychosocial data form, Edinburgh Postpartum Depression Scale(EPDS) and STAI I and II State and Trait Anxiety Scale. Breast milk sodium concentrations were studied from mothers of all infants. The relationship between the development of neonatal HND and risk factors affecting this condition were evaluated. RESULTS: Being the first-born baby of the family was found to be a significant risk factor for HND. Breast milk sodium concentration was 25.8±7.9 mmol/L in the HND group which was significantly higher than the control group. Median depression score was similar in both groups and there was no statistical difference in terms of groups. The anxiety score was higher in the control group compared to the study group. There was no difference in terms of other sociodemographic / psychosocial data of mothers. CONCLUSION: Primiparity or insufficient breastfeeding may result in elevated breast milk sodium levels and related neonatal HND. Breastfeeding support should principally target primiparous women to improve breastfeeding outcomes like as especially HND.

Vitamin D Deficiency Prevalence in Late Neonatal Hypocalcemia: A Multicenter Study

Objective: Late neonatal hypocalcemia (LNH) is a common metabolic problem associated with hypoparathyroidism, high phosphate intake and vitamin D deficiency, often presenting with seizures. In this cross-sectional study, we aimed to evaluate the role of vitamin D deficiency in LNH in Turkey and to describe the characteristics of affected newborns. Methods: Conducted with a cross-sectional design and with the participation of 61 neonatal centers from December 2015 to December 2016, the study included term neonates with LNH (n=96) and their mothers (n=93). Data were registered on the FAVOR Web Registry System. Serum samples of newborns and mothers were analyzed for calcium, phosphate, magnesium, albumin, alkaline phosphatase, intact parathyroid hormone (iPTH) and 25 hydroxyvitamin D [25(OH)D] levels. Results: The median (range) onset time of hypocalcemia was 5.0 (4.0-8.0) days of age, with a male preponderance (60.4%). The median (range) serum 25(OH)D levels of the neonates and their mothers were 6.3 (4.1-9.05) and 5.2 (4.7-8.8) ng/mL, respectively. The prevalence of vitamin D deficiency (<12 ng/mL) was high in both the neonates (86.5%) and mothers (93%). Serum 25(OH)D levels of the infants and mothers showed a strong correlation (p<0.001). While the majority (93.7%) of the neonates had normal/high phosphorus levels, iPTH levels were low or inappropriately normal in 54.2% of the patients. Conclusion: Vitamin D deficiency prevalence was found to be high in LNH. Efforts to provide vitamin D supplementation during pregnancy should be encouraged. Evaluation of vitamin D status should be included in the workup of LNH.

Is Nasal Septum-Tragus Length Measurement Appropriate for Endotracheal Tube Intubation Depth in Neonates? A Randomized Controlled Study.

OBJECTIVE: Endotracheal intubation is a frequent procedure performed in neonates with respiratory distress. Clinicians use different methods to estimate the intubation insertion depth, but, unfortunately, the improper insertion results are very high. In this study, we aimed to compare the two different methods (Tochen's formula = weight in kilograms + 6 cm; and nasal septum-tragus length [NTL] + 1 cm) used to determine the endotracheal tube (ETT) insertion depth. STUDY DESIGN: Infants who had intubation indications were enrolled in this study. The intubation tube was fixed using the Tochen formula (Tochen group) or the NTL + 1 cm formula (NTL group). After intubation, the chest radiograph was evaluated (above T1, proper place, and below T2). RESULTS: A total of 167 infants (22-42 weeks of gestational age) were included in the study. The proper tube placement rate in both groups was similar (32.4 vs. 30.4% for infants < 34 weeks of gestational age and 56.8 vs. 45.0% in infants > 34 weeks of gestational age). The ETT was frequently placed below T2 at a higher rate in infants with a gestational age of <34 weeks, especially in the NTL group (46% in the Tochen group and 60.7% in the NTL group). CONCLUSION: The NTL + 1 cm formula led to a higher rate of ETT placement below T2, especially in infants with a birth weight of <1,500 g. Therefore, more studies are needed to determine the optimal ETT insertion depth.

Explanatory variables and nomogram of a clinical prediction model to estimate the risk of caesarean section after term induction.

The aims of this study were to identify the explanatory variables associated with failure of induction of labour (IOL) and to designate nomograms that predict probability. This retrospective study included 1328 singleton term pregnant women (37-42 weeks). The penalised maximum likelihood estimation (PMLE) method was used instead of traditional logistic regression. Of the 25,678 deliveries that occurred during the study period, 1328 (5.1%) women underwent term delivery. Of those, 1125 (84.7%) had successful vaginal deliveries and 203 (15.3%) had failed vaginal deliveries following use of a dinoprostone slow-release vaginal insert. Explanatory variables were discovered that were associated with delivery failure in term pregnancy undergoing induction of labour with an unfavourable cervix, and a nomogram that predicted probability was developed.IMPACT STATEMENTWhat is already known on this subject? The caesarean rate has continued to climb worldwide over the past decade. Most caesarean sections are performed because of suspected foetal distress or failure to progress. In absolute numbers, most caesarean deliveries are performed in women with a term pregnancy with a foetus in cephalic presentation. Despite these numbers, predicting the mode of delivery by which these women will deliver remains a challenge.What do the results of this study add? Five explanatory variables were strongly associated with failure of dinoprostone delivery of term pregnancies: nulliparity, induction time, premature rupture of membranes, Bishop score and foetal genderWhat are the implications of these findings for clinical practice and further research? The developed nomograms enable fast and easy implementation in clinical practice. After external validation and proof of generalisability, the present model could be used in obstetric clinical management.

Can Hematological Parameters be a Indicator Risk Factor in the Development of Retinopathy of Prematurity?

BACKGROUND: Hematological parameters have been investigated as being indicative of increased inflammatory response in morbidity of very preterm infants. This study aims to determine whether the hematologic parameters and ratios of preterms can be an indicative risk factor for the development of retinopathy of prematurity (ROP). MATERIALS-METHODS: This retrospective cohort study examined newborns born before 32 weeks. Twenty-three patients treated with the diagnosis of ROP were included in the patient group. The control group included 23 patients who did not have ROP (no-ROP). Medical records of eligible preterm infants were retrospectively reviewed. Hemogram samples obtained from all patients during the first 24 h of life and samples of their mothers obtained before delivery were evaluated. The hemogram parameters of white blood cell (WBC) count, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, lymphocyte/monocyte ratio, and platelet mass index were calculated. RESULTS: No difference was observed between the groups in terms of demographic data. In terms of hematological parameters, maternal WBC counts of ROP patients were significantly higher than those of no-ROP patients and WBC counts of ROP patients were significantly lower than those of no-ROP patients. CONCLUSIONS: This study found that high WBC counts in mothers before delivery and/or low WBC counts in preterms during the first postnatal day were higher in developed ROP. These results could lead to the development of prospective studies to assess the real prognostic value of WBC in ROP.

An Observational, Prospective, Multicenter, Registry-Based Cohort Study Comparing Conservative and Medical Management for Patent Ductus Arteriosus.

No consensus has been reached on which patent ductus arteriosus (PDAs) in preterm infants require treatment and if so, how, and when they should be treated. A prospective, multicenter, cohort study was conducted to compare the effects of conservative approaches and medical treatment options on ductal closure at discharge, surgical ligation, prematurity-related morbidities, and mortality. Infants between 240/7 and 286/7 weeks of gestation from 24 neonatal intensive care units were enrolled. Data on PDA management and patients' clinical characteristics were recorded prospectively. Patients with moderate-to-large PDA were compared. Among the 1,193 enrolled infants (26.7 ± 1.4 weeks and 926 ± 243 g), 649 (54%) had no or small PDA, whereas 544 (46%) had moderate-to-large PDA. One hundred thirty (24%) infants with moderate-to-large PDA were managed conservatively, in contrast to 414 (76%) who received medical treatment. Eighty (62%) of 130 infants who were managed conservatively did not receive any rescue treatment and the PDA closure rate was 53% at discharge. There were no differences in the rates of late-onset sepsis, necrotizing enterocolitis (NEC), retinopathy of prematurity, intraventricular hemorrhage (≥Grade 3), surgical ligation, and presence of PDA at discharge between conservatively-managed and medically-treated infants (p > 0.05). Multivariate analysis including perinatal factors showed that medical treatment was associated with increased risk for mortality (OR 1.68, 95% Cl 1.01-2.80, p = 0.046), but decreased risk for BPD or death (BPD/death) (OR 0.59, 95%Cl 0.37-0.92, p = 0.022). The preferred treatment options were ibuprofen (intravenous 36%, oral 31%), and paracetamol (intravenous 26%, oral 7%). Infants who were treated with oral paracetamol had higher rates of NEC and mortality in comparison to other treatment options. Infants treated before postnatal day 7 had higher rates of mortality and BPD/death than infants who were conservatively managed or treated beyond day 7 (p = 0.009 and 0.007, respectively). In preterm infants born at <29 weeks of gestation with moderate-to-large PDA, medical treatment did not show any reduction in the rates of open PDA at discharge, surgical or prematurity-related secondary outcomes. In addition to the high incidence of spontaneous closure of PDA in the first week of life, early treatment (<7 days) was associated with higher rates of mortality and BPD/death.

Neonatal diabetes due to homozygous INS gene promoter mutations: Highly variable phenotype, remission and early relapse during the first 3 years of life.

Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes presenting within the first 6 months of life. INS gene promoter mutations have been shown to cause both remitting/relapsing and permanent NDM. We, herein, present three interesting patients with INS gene promoter mutations. Two cousins with an identical homozygous c.-331C > G mutation presented with NDM. The first cousin had nonremitting diabetes and still requires multidose insulin injections at the current age of 6.1 years. However, the other cousin's diabetes remitted at the age of 9 months, and she is still in remission at the age of 3 years with no medication or dietary intervention required (latest HbA1c was 4.9%). The third patient had NDM also due to a homozygous INS promoter c.-331C>A mutation. Her diabetes remitted at the age of 2 months and relapsed at the age of 2.6 years with severe diabetic ketoacidosis (DKA). Distinct clinical phenotype and relapse with severe DKA in one of the three cases suggest that INS promotor mutations can cause a heterogeneous phenotype and even cases exhibiting remission can relapse unpredictably. Therefore, as the age of relapse is unpredictable, close follow-up and family education on diabetes symptoms are essential for cases with remitting/relapsing diabetes due to INS gene mutations.

The trends in the usage of breast milk in neonatal intensive care setting.

BACKGROUND: Many interventions have been designed to increase breast milk (BM) consumption among preterm and critical-term infants in neonatal units. The aim of this study was to determine the trends in the usage of BM in a neonatal unit and the risk factors for insufficient breast-milk feeding at discharge. METHODS: This retrospective study included newborn infants who hospitalized in the neonatal unit during two periods in different years, a 15-month period in 2012-2013 and in 2017-2018. The primary outcomes were the availability of BM within 24 h after delivery and the status of infant feeding at discharge. RESULTS: During two periods of the study, a total of 3,018 infants were included in the study. The rate of BM expression within the first 24 h after delivery was 92.9%, and it was found that the first period of the study, caesarean section delivery, very low birth weight, being first-time mother, and young maternal age were each independently associated with the delayed initiation of BM expression (P < 0.05). At discharge, 87.6% of the infants had been feeding with BM. Multiple births, the delayed initiation of BM expression, and the length of hospital stay were associated with inadequate BM feeding at discharge (P < 0.001). CONCLUSION: This study showed that interventions supporting BM feeding, which have recently been carried out, made improvements to the initiation of BM expression among mothers whose babies were admitted to the neonatal unit, and in the rate of BM feeding among infants at discharge.

Comparison of the Efficacy Between Intravitreal Aflibercept and Laser Photocoagulation in the Treatment of Retinopathy of Prematurity.

PURPOSE: To compare the efficacy of intravitreal aflibercept and laser photocoagulation in the treatment of retinopathy of prematurity (ROP). METHODS: The files of patients who were diagnosed as having type 1 ROP or aggressive posterior ROP (APROP) and treated with laser photocoagulation and 1 mg/0.025 mL of intravitreal aflibercept were retrospectively analyzed. The patients' birth weight, gestational age, detection week of the disease, zone, stage, presence of plus disease and rubeosis, regression of ROP, re-treatments administered during the follow-up, and spherical equivalent values obtained at the corrected sixth month were recorded. RESULTS: The study included 27 eyes of 15 patients who underwent laser photocoagulation and 24 eyes of 12 patients who received intravitreal aflibercept. Retinal vascularization was in zone II in all eyes in the laser photocoagulation group and zone 1 in 22 eyes (91.7%) in the intravitreal aflibercept group (P < .05). In the laser photocoagulation group, 25 eyes (92.6%) had stage 3 ROP and 2 eyes (7.4%) had stage 2 ROP. In the intravitreal aflibercept group, 14 eyes (58.3%) had stage 3 ROP and 10 eyes (41.7%) had APROP (P < .05). Treatment was established at a postmenstrual age of 37.6 ± 2.5 weeks in the laser photocoagulation group and 34.2 ± 2.4 weeks in the intravitreal aflibercept group (P < .05). The regression rates after treatment were 92.6% and 100%, respectively (P > .05). In the intravitreal aflibercept group, laser photocoagulation was performed on 10 eyes (41.6%) during follow-up visits. Spherical equivalents were measured as +1.10 ± 2.30 and +1.50 ± 2.41 diopters, respectively (P < .05) at the corrected sixth month. CONCLUSIONS: Intravitreal aflibercept is an effective treatment for ROP. However, it requires more additional treatments than laser photocoagulation during the follow-up visits.

Colonización e infección por un microorganismo poco frecuente en una unidad de cuidados intensivos neonatales: tres recién nacidos prematuros con Elizabethkingia meningoseptica / Colonization and infection with a rare microorganism in a neonatal intensive care unit: three preterm infants with Elizabethkingia meningoseptica

Elizabethkingia meningoseptica es un bacilo gramnegativo ampliamente distribuido en la naturaleza pero poco frecuente en humanos que se presenta en infecciones intrahospitalarias. Los avances en las instalaciones de cuidados intensivos neonatales y el uso de dispositivos médicos sofisticados fortalecen la capacidad infecciosa invasiva del microorganismo. Las manifestaciones clínicas suelen incluir bacteriemia primaria, meningitis, neumonía intrahospitalaria, bacteriemia relacionada con el uso de catéteres intravasculares e infecciones gastrointestinales y de las vías biliares. Es posible que, en entornos con recursos limitados, la falta de sistemas de diagnóstico mejorados sea una de las causas por las que no se notifican todas esas infecciones. Resulta bastante difícil distinguir entre colonización e infección, y el patrón de sensibilidad a los antibióticos es diferente. Por consiguiente, los médicos deben realizar el diagnóstico preciso para así evitar el tratamiento incorrecto. En este artículo, describimos tres casos de recién nacidos con diagnóstico de infección y colonización por E. meningoseptica con el objetivo de destacar la importancia del diagnóstico y el tratamiento oportunos de esta bacteria poco frecuente pero letal que ya está presente en las unidades de cuidados intensivos

Elizabethkingia meningoseptica is a widespread gram-negative bacillus in the environment, but a arely reported human pathogen presenting mostly as nosocomial infections. Advances in neonatal intensive care facilities and usage of sophisticated medical devices strengthen the invasive infectious potential of the microorganism. Clinical manifestations usually include primary bacteremia, meningitis, nosocomial pneumoniae, intravascular catheter-related bacteremia and gastrointestinal and biliary tract infections. Lack of improved diagnostic systems in resource constrained settings, might be a cause of underreporting of such infections. Discrimination between colonization and infection is quite difficult, and it has an unusual antibiotic susceptibility pattern. Therefore clinicians should pay special attention to accurate diagnosis in order to prevent mistreatment. Here we report three newborn cases with the diagnosis of E. meningoseptica infection and colopnization, with the aim of drawing attention to the diagnosis and management of this rare but lethal bacteria that is already present in the intensive care unit environment

A rare vascular lesion of newborn: cutis marmorata telangiectatica congenital.

Cutis marmorata telangiectatica congenita is a rare, benign, sporadic and cutaneous vascular disease. A newborn female baby whose mother was aged 29 years and used propylthiouracil during pregnancy was hospitalized because of varicose lesions on the skin of the lower extremity and on the back, which were present at birth. It was observed that the lesions did not disappear, although appropriate room temperature was provided. The patient was diagnosed as having cutis marmorata telangiectatica congenita and screened for additional anomalies. She had no additional anomalies, and she was discharged and monitored. At the postnatal sixth month, the cutaneous vascular lesions disappeared spontaneously. Cutis marmorata telangiectatica congenita, which is a rare condition, should be kept in mind in the differential diagnosis of physiologic cutis marmoratus, which occurs frequently in the neonatal period.

Kutis marmorata telenjiektatika konjenita; nadir görülen, selim, sporadik, deriyi tutan vasküler bir hastaliktir. Yirmi dokuz yasinda hipertroidi nedeni ile propiltiyourasil kullanan anneden dogan kiz bebek, her iki alt ekstremitede ve sirtta yerlesim gösteren renk degisikliginin eslik ettigi variköz lezyonlar nedeniyle yatirildi, lezyonlarin uygun ortam sicakligi saglanmasina ragmen düzelmedigi saptandi. Kutis marmorata telenjiektatika konjenita tanisi konan olgu; eslik edebilecek ek anomaliler açisindan tarandi; ek anomali saptanmayan olgu taburcu edilerek izleme alindi, postnatal altinci ayda kutanöz vasküler lezyonlarin kendiliginden kayboldugu görüldü. Yenidogan döneminde sik olarak karsimiza çikan fizyolojik kutis marmoratus ayirici tanisinda, ender görülen bir durum olan kutis marmorata telenjiektatika konjenita da akilda tutulmalidir.

Prevalencia de microorganismos patógenos respiratorios durante dos temporadas consecutivas de virus sincicial respiratorio en un centro de atención de alta complejidad / Prevalence of respiratory pathogens during two consecutive respiratory syncytial virus seasons at a tertiary medical care center

Objetivo. Determinar el perfil etiológico de la infección de vías respiratorias bajas (IVRB) en los neonatos durante la temporada de virus sincicial respiratorio (VSR) y definir las características de esta y otras infecciones. Métodos. Estudio retrospectivo con neonatos hospitalizados por IVRB durante dos temporadas de VSR, con reacción múltiple en cadena de la polimerasa en tiempo real. Se revisaron los datos relevantes y se compararon las características de la infección por VSR con las de otros microorganismos. Resultados. Entre 224 pacientes, 160 (71 %) fueron positivos para, al menos, un agente causal potencial. Entre ellos, el 65 % tenía VSR y el 15 %, más de un agente (coinfección). En el grupo con VSR, hubo más dificultad respiratoria (p < 0,01), radiografías de tórax anormales (p < 0,01), requerimiento de atención en terapia intensiva (p < 0,01) y más días de oxigenoterapia (p < 0,01). No obstante, hubo menos casos de fiebre al ingreso y menos días de antibioticoterapia (en ambos, p < 0,01), y la duración de la hospitalización no fue más prolongada. Los pacientes con coinfección requirieron atención en terapia intensiva en mayor medida que los demás (25 % contra 6,5 %, p < 0,01). Conclusión. Este estudio demostró que el VSR fue más frecuente en los neonatos hospitalizados por IVRB durante la temporada y condujo a una evolución más grave que otros microorganismos patógenos detectados. Posiblemente la gravedad de la infección por VSR se viera aumentada por la presencia de una coinfección y radiografía de tórax anormal.

Aim: To determine the etiological profiles of lower respiratory tract infection (LRI) in neonates during respiratory syncytial virus(RSV) season, and to define the clinical features of RSV-related infection and others. Methods: The retrospective study included newborn infants who were hospitalized for LRI during the two consecutive RSV seasons, and then tested for possible etiological agent by multiplex real-time polymerase chain reaction. All relevant data were reviewed, and the clinical characteristics of RSV-related infection were compared to those of others. Results: Of 224 patients, 160 (71 %) were positive for at least one potentially causative agent. Of them, 65 % had RSV, and 15 % had more than on ecausative agent (co-infection). The RSV group had more the findings of respiratory distress (p< 0.01), abnormal chest radiography (p< 0.01), need for intensive care (p< 0.01), and duration of oxygen requirement (p< 0.01) but less fever on admission and duration of antibiotic use (for both, p< 0.01), and no longer hospital stay. Need of intensive care nursery was more common in patients with co-infection than others (25 % vs. 6.5 %, p< 0.01). Conclusion: This study highlighted that RSV was the most frequent agent in neonates hospitalized for LRI during the season, with a more severe clinical course than other detected pathogens. The disease severity of RSV infection may have seemed to be increased by the presence of coinfection and abnormal chest radiography.
