RESUMEN
Neonatal osteomyelitis (OM), although exceptionally rare, has been linked to detrimental sequel, as diagnosis in the early stages is challenging and any delay in treatment can lead to disturbance in skeletal growth. In pediatric OM the most commonly grown bacteria is Staphylococcus aureus followed by group A Streptococcus (GAS). Notwithstanding, sepsis-induced coagulopathy is a well-known entity in children and adults, still sepsis-associated thrombosis is sparsely observed. we present a case of a newborn with GAS associated OM and thrombosis. A term neonate on the 11th day of life was referred to our NICU due to right (R) lower limb edema, cyanosis and core temperature up to 39 °C. Late onset sepsis was suspected and started on vancomycin and amikacin. A colour Doppler scan showed thrombosis of the R common femoral vein. The neonate started on iv unfractionated heparin. Ampicillin was added given positive for GAS blood culture. An MRI on the 5th day of admission, showed evidence of thrombosis resolution. On the 14th day of admission, a bone Tc99 scan showed evidence of OM of R femur. Antibiotic treatment switched to amoxicillin per os. The management was restricted to anticoagulant therapy with low molecular weight heparin for 3 months and antibiotic therapy for 6 months without surgery intervention and the patient recovered and discharged at 42 days of age. Early diagnosis and treatment of neonatal osteomyelitis can prevent bone destruction. Sepsis-associated thrombosis is barely observed during osteomyelitis, yet it should be considered as an emerged case requiring prompt treatment.

To assess the potential benefit from the implementation of the Kaiser Permanente early-onset sepsis calculator (EOS-C), in terms of antibiotic use and requested laboratory tests, in a network of neonatal intensive care units (NICUs) in Greece, and to determine the incidence of early-onset sepsis (EOS) in Greek NICUs, a prospective surveillance study was conducted in 7 NICUs between April 2018 and June 2019. Data were collected for all newborns ≥ 34 weeks' gestation receiving empiric antibiotic therapy within the first 3 days of life. The number of live births and positive blood or cerebrospinal fluid cultures within the first 3 days of life were used for calculation of EOS incidence. Evaluation of possible impact of implementing the calculator was done by comparing the clinicians' recorded management to the calculator's suggested course of action. The unit-specific incidence of culture-proven EOS ranged between 0 and 2.99/1000 live births. The weighted incidence rate for all 7 units was 1.8/1000 live births. Management of EOS guided by the calculator could lead to a reduction of empiric antibiotic initiation up to 100% for the group of "well-appearing" neonates and 86% for "equivocal," lowering exposure to antibiotics by 4.2 and 3.8 days per neonate, respectively. Laboratory tests for blood cultures drawn could be reduced by up to 100% and 68%, respectively. Sensitivity of the EOS-C in identifying neonates with positive blood cultures was high.Conclusion: Management strategies based on the Kaiser Permanente neonatal sepsis calculator may significantly reduce antibiotic exposure, invasive diagnostic procedures, and hospitalizations in late preterm and term neonates. What is Known: ⢠Neonates are frequently exposed to antibiotics for presumed EOS. ⢠The Kaiser Permanente sepsis calculator can reduce antibiotic exposure in neonates.. What is New: ⢠EOS calculator can be an effective antibiotic stewardship tool in a high prescribing country and can reduce invasive diagnostic procedures and mother-baby separation. ⢠Incidence of EOS in Greece is higher compared to other European countries.

AIM: The aim of this review was to compile existing evidence on the role of platelets in the development of severe retinopathy of prematurity (ROP), highlight the strengths and weaknesses of the available studies and critically discuss the reported data. METHODS: A comprehensive literature search was conducted on PubMed from January 2000 to January 2022, and the reference lists of the included studies were screened manually. RESULTS: There were 19 primary studies that fulfilled the eligibility criteria. Experimental research indicated lower platelet count in mice oxygen-induced retinopathy model compared with normoxia controls, while platelet transfusions suppressed neovascularisation. The latter finding was not consistently confirmed in clinical research, where a low platelet count, an increased number of thrombopenic episodes and of platelet transfusions have all been implicated in the development of ROP requiring treatment, either type I or aggressive posterior or both. However, existing studies exhibit significant clinical heterogeneity and present methodological limitations that imperil their reliability and validity. CONCLUSION: Platelet deficiency has been associated with severe ROP. However, critical thresholds of platelet parameters are still unrecognised. Future research is required to determine whether platelet parameters can be predictive biomarkers for ROP requiring treatment and at what thresholds.

Objective To examine cerebral oxygenation and perfusion in small for gestational age (SGA) compared with appropriate for gestational age (AGA) neonates during the first postnatal week, and to investigate any association with neurodevelopmental outcomes at 24-36 months of age. Methods A prospective matched case-control study was conducted evaluating cerebral oxygenation and perfusion, using near-infrared spectroscopy (NIRS), between SGA and AGA neonates, during the first postnatal week. A neurodevelopmental assessment with Bayley-III was performed at 24-36 months of age. Results Forty-eight SGA and 48 AGA neonates of similar gestation (32.8 ± 2.1 vs. 32.5 ± 1.9) were enrolled. On the first postnatal day, the cerebral oxygenation was equal between SGA and AGA neonates (71 ± 7% vs. 72 ± 8%); however, in the subgroup analysis, males had higher oxygenation compared to female SGA neonates (73 ± 7% vs. 69 ± 7%, P = 0.04). Cerebral perfusion was significantly higher in SGA neonates on the first postnatal day (1.4 ± 0.6 vs. 1.1 ± 0.5, P = 0.04), but this difference was diminished on subsequent measurements. There were no significant differences between the SGA and AGA infants regarding the composite cognitive, communication and motor index scores. The length of mechanical ventilation and late-onset sepsis were significant risk factors affecting the cognitive and communication composite index scores, respectively. Conclusion Cerebral oxygenation was equal between SGA and AGA neonates, while cerebral perfusion was transiently increased in SGA neonates during the first postnatal day. There was no significant association of cerebral oxygenation and perfusion with neurodevelopmental outcomes.

PURPOSE: There is a large variation in mydriatic regimens used in screening for retinopathy in preterm infants. Except for the standard instillation of mydriatic drops in their commercial formulation, other techniques for pupil dilation have also been described. This study aimed to review all techniques that have been used for mydriasis in retinopathy of prematurity eye examination (ROPEE) screening. METHODS: A comprehensive literature search was performed in PubMed, Cochrane library, Trip database, and Scopus, using the key words: "mydriasis", "techniques", "mydriatics", "dilating drops", "retinopathy of prematurity", "ROP", "phenylephrine", "cyclopentolate", "tropicamide", "smaller mydriatic drops", "reduction in drop size" to February 2019. RESULTS: Five primary studies were included, assessing the techniques of microdrops, lower conjunctival fornix (LCF) packing and Mydriasert® ophthalmic insert. Reported efficacy was similar to commercial eyedrops instillation. Microdrops appeared to have a superior safety profile. LCF packing and Mydriasert lead to increased blood pressure, without serious complications, necessitating further safety studies. CONCLUSIONS: Of all alternative mydriasis techniques for ROPEE screening that have been described, microdrops appear to be the safest yet still effective technique in the fragile population of premature infants in risk of ROP.

PURPOSE: To compile real-time data on the preferred mydriasis practice patterns for retinopathy of prematurity (ROP) screening in Europe. METHODS: A cross-sectional online survey was conducted from December 2022 to January 2023, using a self-report online questionnaire which was distributed via email to the members of the European Pediatric Ophthalmological Society and the Greek National ROP Task Force. A six-week period of recruitment was determined, and a reminder email was sent after two weeks. Descriptive statistics were used to explore the data, which was summarized with frequencies and percentages. RESULTS: Sixty-six responses were recorded (response rate: 29.5%), representing practices in 55 Neonatal Intensive Care Units from 21 European countries. In 94.5%, the applied mydriatic regimen consists of phenylephrine with at least one muscarinic antagonist, either tropicamide or cyclopentolate. The concentration of phenylephrine ranges from 0.5% to 5%, of tropicamide from 0.25% to 1%, and of cyclopentolate from 0.2% to 1%. The most commonly used regimen (43.6%) contains phenylephrine 2.5% and tropicamide 0.5%, administered either combined or separately. About 54.5% of the reported mydriatic solutions are non-commercial, in-house preparations. Systemic adverse events, including oxygen desaturation, bradycardia and cardiopulmonary arrest were reported in 14.5%. CONCLUSION: There is considerable heterogeneity in the applied mydriatic regimens for ROP screening in Europe, reflecting the absence of universal guidelines. The wide use of in-house preparations underlines the gap in the pharmaceutical industry. Concern should be raised against the wide use of undiluted commercial drugs, that reach adult dose, in the fragile population of preterm infants.
RESUMEN
Preeclampsia is a human-specific hypertensive disorder of gestation. It is associated with short-term adverse effects in the fetus and long-term complications in the neonate, mainly due to disrupted blood flow during critical periods of intrauterine development. An ischemic event in the uterus can affect many systems of the fetus, including a small bowel involvement. We present a case of a preterm, small for gestational age neonate with severe intrauterine growth restriction, small bowel stenosis, and volvulus without malrotation, born to a mother with severe preeclampsia.
RESUMEN
PURPOSE: The purpose of the study was to investigate the association of platelet parameters and postnatal weight gain with treatment-requiring ROP (TR-ROP). METHODS: In this retrospective matched case-control study, infants with TR-ROP were individually matched, according to gestational age and birth weight, with one or two untreated infants who developed no or spontaneously regressed ROP. Longitudinal data on platelet count (PLT), mean platelet volume (MPV), daily weight and platelet transfusions were collected. Platelet mass index (PMI) and weight standard deviation score (WSDS) were also calculated. Conditional logistic regression analysis was performed to adjust for matching. RESULTS: Fourteen cases, presenting type I ROP, and 25 matched controls were included. The odds of developing TR-ROP decreased as PLT increased during 31st week of postmenstrual age (PMA) or during 1st and 2nd week of postnatal age (PNA). The odds of developing TR-ROP were 16.7 times higher in infants receiving at least one platelet transfusion compared with those who were not transfused. The odds of developing TR-ROP increased by 31.2% as the mean volume of platelet transfusion per infant increased by 1 ml. The odds of developing TR-ROP decreased as PMI increased during 1st week PNA, and as weight and WSDS increased during 4th -6th week PNA. Analysis of MPV, number of thrombopenic episodes per infant, number of platelet transfusions per infant and days with WSDS < -2 showed no association with TR-ROP. CONCLUSION: To our knowledge, this is the first study ascertaining an association of platelet transfusions with type I ROP. Prospective cohort studies are required to confirm our findings.

BACKGROUND: Atopic dermatitis (AD) at a young age often precedes the development of food allergies. Although AD affects millions of infants worldwide, prenatal and postnatal risk factors, and their association with the development of food allergies later on, are not fully elucidated. This study seeks to investigate AD epidemiology in infancy and its risk factors, examining early-life factors (both prenatal and postnatal) that could contribute to the later development of food allergies. METHODS: Between January 2019 and December 2019, 501 infants were included in this prospective cohort study. Longitudinal data collection was performed through maternal interviews, the first one conducted within three days after the delivery and the second within 24 to 36 months after the delivery, encompassing variables such as demographics, family history of atopy, maternal smoking, antibiotic use during pregnancy, the mode of delivery, breastfeeding history, food practices, and greenness exposure within 3 days from delivery, while they were still in the hospital. RESULTS: Maternal smoking during pregnancy (p = 0.001) and an older sibling atopy history (p = 0.03) was significantly linked to AD incidence. Cesarean section delivery (p = 0.04) was associated with a higher risk of food allergies in infants with AD. Having a garden at home correlated with a higher likelihood of AD (p = 0.01), and food elimination without medical guidance (p = 0.02) due to AD correlated with an elevated risk of food allergies. CONCLUSIONS: Encouraging timely allergenic food introduction while promoting dietary diversity, rich in plant-based foods, maternal smoking cessation, and professional dietary guidance may help minimize AD and food allergy risk. Future studies should address the role of greenness in the development of AD and food allergies.

OBJECTIVE: Chorioamnionitis and fetal inflammatory response syndrome (FIRS) are significant risk factors for early onset sepsis (EOS). Recently, the use "Intrauterine Inflammation or Infection or both" or triple I has been proposed, classifying cases into an isolated maternal fever, suspected triple I, or confirmed chorioamnionitis. Evidence suggests that the association between suspected chorioamnionitis and confirmed histological chorioamnionitis (HCA) is not consistent, as well as the impact of HCA on the development of EOS.We aimed to evaluate the association between suspected chorioamnionitis and HCA, the impact of HCA on EOS, and the effect of antepartum antibiotic prophylaxis on EOS. METHODS: We retrospectively reviewed the medical records of all infants admitted to our institution, between 2017 and 2018, with a diagnosis of chorioamnionitis. We recorded the clinical evidence of chorioamnionitis, the histologic report of the placenta, the maternal and neonatal data, the neonatal inflammatory markers including C-reactive protein (CRP), and the incidence of EOS. The impact of antepartum antibiotic prophylaxis on the infants' CRP and EOS was calculated, and the logistic regression model was performed to estimate the association of confirmed HCA with EOS, while controlling for FIRS stage, gestation age, birth weight, maternal fever, foul-smelling amniotic fluid, and prolonged rupture of membranes. RESULTS: During the study period, a total of 266 infants were identified; 81 (30%) infants had a confirmed HCA (HCA-present cases), and 185 (70%) infants were diagnosed with suspected triple I (HCA-absent cases). Antepartum antibiotics had been commenced in a significantly higher proportion in HCA-present cases (46%) in comparison to 14% of HCA-absent cases (p < .001). HCA-present infants were of significantly lower gestation (31.6 ± 4weeks versus 33.3 ± 4weeks, p = .004), and birth weight (1826 ± 840 g versus 2092 ± 849 g, p = .019), they had a significantly higher rate of clinical symptoms (31% versus 6%, p < .001), and a higher CRP at birth and 24 h (1.4 ± 1.5 mg/dL versus 0.3 ± 0.2 mg/dL, p < .001, and 2.1 ± 2.3 mg/dL versus 0.4 ± 0.6 mg/dL, p < .001, respectively). All HCA-present cases had evidence of FIRS; 43% were stage I, 25% stage II, and 32% were FIRS stage III. A significantly higher proportion of HCA-present infants were diagnosed with EOS (46% as compared to 6%, p < .001). The antepartum antibiotic administration was related to a significantly lower CRP at birth and 24 h only in HCA-present cases, albeit not with any reduction ιn EOS incidence. HCA was significantly associated with EOS (RR 3.18, 95% CI 2.81-5.18, p < .001). After adjusting for perinatal factors, the presence of HCA (OR 7.89, 95% CI 1.19-23.34, p = .032) and an advanced FIRS stage (OR 10.35, 95% CI 4.23-25.32, p < .001) were significantly associated with EOS. CONCLUSIONS: Amongst infants with suspected chorioamnionitis, the diagnosis is partially supported by histological confirmation, and that is more prominent in pregnancies of a lower gestation. The presence of HCA and an advanced FIRS stage predispose to an increased risk of EOS after adjusting for other perinatal and neonatal factors. The antepartum prophylaxis against intra-amniotic infection was related to a significantly lower CRP in HCA-present cases.

PURPOSE: To study the safety and efficacy of indirect ophthalmoscopy with (Sp) or without (speculum free, SpF) the use of lid speculum and scleral indentation for retinopathy of prematurity (ROP) screening. METHODS: In this crossover randomized controlled trial, preterm infants received either the Sp on their first and the SpF technique on their second examination a week later or vice versa. Video recordings of the infants' reactions were assessed by two observers, using Premature Infant Pain Profile-Revised score and the crying score of the Bernese Pain Scale for Neonates. Fundoscopy adequacy, its duration and adverse events within the first 24 hr postscreening were also recorded. RESULTS: Thirty-seven infants with median (interquartile range) gestational age of 28.7 (28.0, 30.2) weeks and mean (standard deviation, SD) birth weight 1225 (377) grams were enrolled. The mydriasis-induced stress was similar between the Sp and SpF exam (mean difference [MD]: 0.78, 95% confidence interval [CI]: -0.83, 2.38; p = 0.33). The stress induced by fundoscopy (MD: 4.98, 95% CI: 3.58, 6.37; p < 0.001) and examination overall (MD: 2.32, 95% CI: 0.96, 3.67; p = 0.001) were higher in the Sp than in the SpF exam, and so was the crying score during fundoscopy (MD: 1.31, 95% CI: 1.06, 1.56; p < 0.001). Adverse events in the two groups were similar (p = 0.13). Fundoscopy was adequate in identifying the absence of treatment-requiring ROP in all cases, and lasted longer in the Sp than in the SpF exam (p < 0.001). CONCLUSION: Our study suggests that the use of speculum and indentation should be reserved for the few cases where fundus visualization is insufficient for excluding the presence of severe ROP.

OBJECTIVE: To study the efficacy and safety of mydriatic microdrops compared with standard drops for retinopathy of prematurity (ROP) screening. STUDY DESIGN: Preterm infants undergoing ROP screening received microdrops and standard drops of phenylephrine 1.67% and tropicamide 0.33% in a random allocation sequence at two consecutive weekly examinations. Primary outcome was pupil diameter measured by two masked observers at 45 (T45) and 90 (T90) minutes after instillation. RESULTS: Twenty-five infants were randomized. No differences observed in mean pupil diameter after either administration technique at all time points (T45 Mean Difference: -0.14; 95% Confidence Interval: -0.38, 0.09; p = 0.23). Heart rate values at T120 were lower after microdrop instillation (p = 0.046). Otherwise, adverse events did not differ after either administration technique. CONCLUSION: This pilot study provides evidence of microdrops mydriasis efficacy, while justifying a full-scale trial to confirm their non-inferiority compared with standard drops and provide more data about safety.

BACKGROUND: Retinopathy of prematurity (ROP) eye examination screening presupposes adequate mydriasis for an informative fundoscopy of preterm infants at risk, on a weekly basis. Systemic absorption of the instilled mydriatic regimens has been associated with various adverse events in this fragile population. This report aims to present the fully developed protocol of a full-scale trial for testing the hypothesis that the reduced mydriatic drop volume achieves adequate mydriasis while minimizing systemic adverse events. METHODS: A non-inferiority crossover randomized controlled trial will be performed to study the efficacy and safety of combined phenylephrine 1.67% and tropicamide 0.33% microdrops compared with standard drops in a total of 93 preterm infants requiring ROP screening. Primary outcome will be the pupil diameter at 45 (T45) min after instillation. Pupil diameter at T90 and T120 will constitute secondary efficacy endpoints. Mixed-effects linear regression models will be developed, and the 95% confidence interval approach will be used for assessing non-inferiority. Whole blood samples will be analyzed using hydrophilic liquid chromatography-tandem mass spectrometry method (HILIC-MS/MS), for gathering pharmacokinetic (PK) data on the instilled phenylephrine, at nine specific time points within 3 h from mydriasis. Pooled PK data will be used due to ethical restrictions on having a full PK profile per infant. Heart rate, oxygen saturation, blood pressure measurements, and 48-h adverse events will also be recorded. DISCUSSION: This protocol is designed for a study powered to assess non-inferiority of microdrops compared with standard dilating drops. If our hypothesis is confirmed, microdrops may become a useful tool in ROP screening. TRIAL REGISTRATION: ClinicalTrials.gov NCT05043077 . Registered on 2 September 2021.

Antibiotics are commonly prescribed in Neonatal Intensive Care Units (NICU), where stewardship interventions are challenging. Lowering antibiotic consumption is desperately needed in Greece, a country with high antibiotic resistance rates. We sought to assess the effectiveness of a low-cost and -resource intervention to reduce antibiotic use in Greek NICUs implementing a "low-hanging fruit" approach. A prospective quasi-experimental study was conducted in 15/17 public NICUs in Greece (9/2016-06/2019). The intervention selected was discontinuation of antibiotics within 5 days for neonates with gestational age ≥ 37 weeks, no documented signs or symptoms of sepsis, CRP ≤ 10 mg/L and negative cultures within 3 days of antibiotic initiation. Impact was evaluated by the percentage of discontinued regimens by day 5, length of therapy (LOT) and stay. Trends of antibiotic consumption were assessed with days of therapy (DOT) per 1000 patient-days. Overall, there was a 9% increase (p = 0.003) of antibiotic discontinuation in ≤5 days. In total, 7/13 (53.8%) units showed a ≥10% increase. Overall, 615 days on antibiotics per 1000 patients were saved. Interrupted time-series analysis established a declining trend in DOT/1000 patient-days relative to the pre-intervention trend (p = 0.002); a monthly decrease rate of 28.96 DOT/1000 patient-days (p = 0.001, 95%CI [-45.33, -12.60]). The intervention had no impact on antibiotic choice. Antibiotic use was successfully reduced in Greek NICUs using a "low-hanging fruit" approach. In resource-limited settings, similar targeted stewardship interventions can be applied.
RESUMEN
Maternal diet before and during pregnancy plays an important role for the developing fetus. Any eating disorder in this period can cause transient or/and permanent negative effects on the mother and her offspring.
RESUMEN
BACKGROUND: Adequate nutrition is essential for optimal neurodevelopment to preterm infants. Our aim was to evaluate the impact of caloric deprivation on Bayley-III scales performance at 18-24 months of corrected age, in a cohort of preterm infants. METHODS: We prospectively enrolled infants with gestational age <30 weeks and birth weight <1500â¯g. Apart from a whole cohort analysis, we performed a subgroup analysis between infants received inadequate calories (<85 Kcal/kg/day) during the first two weeks of age, compared to a standard nutrition group. All infants underwent a Bayley-III assessment at 18-24 months of corrected age. RESULTS: From the 63 preterm infants analysed, 25% had caloric deprivation compared to 75% with adequate nutrition. Caloric deprived infants were of lower gestational age and birth weight, and received a lower amount of enteral feeding during the first 14 days of age. There were no differences between the two groups regarding the common neonatal co-morbidities. Caloric deprived infants had significantly lower composite index scores at 18-24 months of corrected age. Caloric deprivation, late onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia were significant risk factors of neurodevelopmental impairment. CONCLUSIONS: Several neonatal factors affect the neurodevelopmental outcome of preterm infants, and nutrition may pose an important role.
