Integrating Clinical and Neuroimaging Markers to Predict the Onset of Posthemorrhagic Ventricular Dilatation in Preterm Neonates.

BACKGROUND: Posthemorrhagic ventricular dilatation (PHVD) is a major complication of intraventricular hemorrhage (IVH); it is associated with high risks of cerebral palsy and cognitive deficits compared with infants without PHVD. This study aims to explore the early perinatal risk factors-associated with the risk of progressive PHVD. METHODS: Neonates ≤29 weeks gestational age (GA) with Grade II-III IVH and periventricular hemorrhagic infarct (PVHI) between 2015 and 2021 were retrospectively reviewed. All cranial ultrasounds done within 14 days postnatal age (PNA) were assessed for grade of IVH, anterior horn width (AHW), ventricular index (VI), and thalamo-occipital index (TOD). The outcome was defined as death of any cause or VI and/or AHW and/or TOD ≥ moderate-risk zone based on an ultrasound done beyond two weeks PNA. RESULTS: A total of 146 infants with a mean GA of 26 ± 1.8 weeks, birth weight 900 ± 234 g were included, 46% were females. The primary outcome occurred in 56 (39%) infants; among them 17 (30%) and 11 (20%) needed ventricular reservoir and shunt insertion, respectively. The risk factors present within 14 days PNA that significantly increased the odds of developing PHVD were hemodynamically significant patent ductus arteriosus (odds ratio [OR] 6.1, 95% confidence interval [CI] 1.9 to 22), culture-proven sepsis (OR 5.4, 95% CI 1.8 to 18), Grade III IVH (OR 4.6, 95% CI 1.1 to 22), PVHI (OR 3.0, 95% CI 0.9 to 10), and VI (OR 2.1, 95% CI 1.6 to 2.9). CONCLUSIONS: Clinical predictors such as significant ductus arteriosus and bacterial septicemia, along with risk levels of AHW and VI measured with early cranial ultrasounds, are potential predictors of subsequent onset of PHVD.

Premature newborns with intraventricular hemorrhage do not have vasospasm pattern by cranial Doppler ultrasound: A pilot study.

Preterm neonates are at risk for neurodevelopmental impairment, especially those with intraventricular hemorrhage (IVH). Cerebral vasospasm (VSP) is a common complication after subarachnoid hemorrhage (SAH) in adult population, but it is unknown if preterm neonates with IVH may develop it. We prospectively enrolled premature newborns < 32 weeks with IVH and without IVH. All patients received serial transcranial sonography through the temporal window of the middle cerebral artery, anterior cerebral artery, posterior cerebral artery, and the internal carotid artery with transcranial Doppler sonography days 2, 4, and 10 of life. Cerebral blood velocities (CBFVs) were measured including median velocity flow (MV), peak systolic velocity (PSV), and maximum end-diastolic velocity (EDV). Resistance index and pulsatility index were calculated. VSP was defined as an increase of 50% in the baseline velocity per day and/or a Lindegaard ratio higher than 3. Fifty subjects were enrolled. None of the patients with IVH showed elevation of MV or a Lindegaard ratio > 3. There were no differences between IVH and without IVH groups regarding resistance index and pulsatility index.    Conclusion: Preterm infants with IVH do not present a pattern of VSP analyzed by Doppler transcranial ultrasound in this pilot study. What is Known: • In adult population with subarachnoid hemorrhage the most treatable cause of cerebral ischemia is due cerebral vasospasm but is unknown if premature newborn may have vasospasm due the extravasation of blood in the context of intraventricular hemorrhage What is New: •In this pilot study we did not find in premature newborn with intraventricular hemorrhage signs of vasoespam measured by transcranial color doppler ultrasound.

Early skin-to-skin contact and the risk of intraventricular haemorrhage and sepsis in preterm infants.

AIM: This study aimed to investigate the risks of intraventricular haemorrhage (IVH) or sepsis in extremely and very preterm infants exposed to early skin-to-skin contact (SSC). METHODS: Data from the Swedish Neonatal Quality Register from 2015 to 2021 were extracted to compare the proportions of infants exposed and not exposed to SSC on day 0 and/or 1 in life that developed IVH or sepsis. RESULTS: A total of 2514 infants, 1005 extremely preterm and 1509 very preterm, were included. This amounted to 69% of all extremely and very preterm infants born during the study period. The proportion of infants with IVH exposed and not exposed to early SSC was 11% and 27%, an adjusted odds ratio (aOR) of 0.67 (95%CI 0.52-0.86, p = 0.002). The proportion of infants with sepsis exposed and not exposed to early SSC was 16% and 30%, an aOR of 0.94 (95%CI 0.75-1.2, p = 0.60). For extremely preterm infants, the proportion with sepsis when exposed and not exposed to early SSC was 29% and 44%, an aOR of 0.65 (95%CI 0.46-0.92, p = 0.015). CONCLUSION: In the current setting, the risk of IVH or sepsis is not increased when an extremely or very preterm infant is exposed to early SSC.

Risk factors associated with intraventricular hemorrhage in very-low-birth-weight premature infants.

PURPOSE: To analyze the association between risk factors and severe intraventricular hemorrhage (grade II-IV) in PNB under 1500 g. METHODS: Multicenter, retrospective, analytical, case-control study in PNB under 34 weeks and under 1500 g admitted to the NICU. CASE: PNB with severe intraventricular hemorrhage (grade II-IV). Logistic regression analysis was used to adjust for IVH-associated variables and odds ratios (OR). RESULTS: A total of 90 PNB files were analyzed, 45 cases and 45 controls. The highest risk factors for severe IVH were lower gestational age (OR 1.3, p < 0.001), perinatal asphyxia (OR 12, p < 0.001), Apgar < 6 at minute 1 and 5 (OR 6.3, p < 0.001). CONCLUSION: Lower gestational age, birth asphyxia, Apgar score lower of 6, and respiratory-type factors are associated with increased risk for severe IVH.

The Frequency of Intraventricular Hemorrhage and its Risk Factors.

BACKGROUND: Intraventricular hemorrhage (IVH) (is the most prevalent type of cerebrovascular accident in premature infants, which can result in lasting neurological complications. The aim of this study was to ascertain the frequency of IVH and its associated risk factors within our particular context. MATERIALS AND METHODS: This cross-sectional study was carried out in a tertiary neonatal intensive care unit of a maternal and neonatal hospital from September 2018 to August 2019. Premature infants under 34 weeks of age and with birth weight < 1500 grams who did not have significant congenital anomalies participated in the study. A brain ultrasound was performed by a sonologist during the first week. The infants were subsequently categorized into two groups: those with and without IVH. A comparative analysis was conducted using the chi-square test and logistic regression. A significance level of p<0.05 was considered statistically significant. RESULTS: Of the 205 premature infants who completed the study, IVH was reported in 107 cases (52.1%), of which 97.3% of ventricular hemorrhages were grade I and II and 2.7% accounted for severe bleeding (grade III and IV). Gestational age less than 28 weeks, weight less than 1000 g, vaginal delivery, asphyxia and resuscitation, history of intubation and mechanical ventilation, cord blood acidity, dopamine infusion, and history of fever and chorioamnionitis in the mother have been found to be significantly associated with increased risk of IVH (p<0.001). Antenatal corticosteroids decreased the risk (OR=10.63). CONCLUSION: In this study, IVH has been found to be common in infants under 1500 g of weight, but the severe form was low in frequency and was observed significantly in high-risk pregnancies.

The role of the brain-sparing effect of growth-restricted fetuses in newborn germinal matrix/intraventricular hemorrhage.

OBJECTIVES: The aim of the study was to evaluate the effect of the brain-sparing effect (BSE) of fetal growth restriction (FGR) in newborn germinal matrix/intraventricular hemorrhage (GM/IVH). METHODS: A total of 320 patients who delivered prior to the 34th gestational week were analyzed from data records. 201 patients were divided into two groups according to cerebro-placental ratio (CPR): early fetal growth restriction (FGR) with abnormal CPR group (n=104) and appropriate for gestational age with normal Doppler group (control) (n=97). Using the normal middle cerebral artery (MCA) Doppler as a reference, multivariate logistic regression analysis was used to assess the association between the BSE and the primary outcome. RESULTS: The rate of Grade I-II germinal matrix/intraventricular hemorrhage (GM/IVH) was 31(29.8%) in the group possessing early FGR with abnormal CPR and 7(7.2%) in the control group, showing a statistically significant difference. The rate of grade III-IV GM/IVH was 7(6.7%) in the group possessing early FGR with abnormal CPR and 2 (2.1%) in the control group, showing no statistically significant difference. We found that gestational age at delivery <32 weeks was an independent risk factor for GM/IVH. In addition, we found that other variables such as the presence of preeclampsia, fetal weight percentile <10, emergency CS delivery, 48-h completion after the first steroid administration and 24-h completion rate after MgSO4 administration were not independently associated with the primary outcome. CONCLUSIONS: Our results indicate that the rate of GM-IVH was increased in the group possessing early FGR with abnormal CPR; however, multivariate logistic regression analysis showed that BSE was not an independent risk factor for GM/IVH.

Mode of delivery and adverse short- and long-term outcomes in vertex-presenting very preterm born infants: a European population-based prospective cohort study.

OBJECTIVES: To compare mortality, morbidity and neurodevelopment by mode of delivery (MOD) for very preterm births with low prelabour risk of caesarean section (CS). METHODS: The study was a population-based prospective cohort study in 19 regions in 11 European countries. Multivariable mixed effects models and weighted propensity score models were used to estimate adjusted odds ratios (aOR) by observed MOD and the unit's policy regarding MOD. Population: Singleton vertex-presenting live births at 24 + 0 to 31 + 6 weeks of gestation without serious congenital anomalies, preeclampsia, HELLP or eclampsia, antenatal detection of growth restriction and prelabour CS for fetal or maternal indications. RESULTS: Main outcome measures: A composite of in-hospital mortality and intraventricular haemorrhage (grade III/IV) or periventricular leukomalacia. Secondary outcomes were components of the primary outcome, 5 min Apgar score <7 and moderate to severe neurodevelopmental impairment at two years of corrected age. The rate of CS was 29.6% but varied greatly between countries (8.0-52.6%). MOD was not associated with the primary outcome (aOR for CS 0.99; 95% confidence interval [CI] 0.65-1.50) when comparing units with a systematic policy of CS or no policy of MOD to units with a policy of vaginal delivery (aOR 0.88; 95% CI 0.59-1.32). No association was observed for two-year neurodevelopment impairment for CS (aOR 1.15; 95% CI 0.66-2.01) or unit policies (aOR 1.04; 95% CI 0.63-1.70). CONCLUSIONS: Among singleton vertex-presenting live births without medical complications requiring a CS at 24 + 0 to 31 + 6 weeks of gestation, CS was not associated with improved neonatal or long-term outcomes.

Severity of Bronchopulmonary Dysplasia Among Very Preterm Infants in the United States.

BACKGROUND AND OBJECTIVES: The Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network recently proposed new, severity-based diagnostic criteria for bronchopulmonary dysplasia (BPD). This study provides the first benchmark epidemiological data applying this definition. METHODS: Retrospective cohort study of infants born from 22 to 29 weeks' gestation in 2018 at 715 US hospitals in the Vermont Oxford Network. Rates of BPD, major neonatal morbidities, and common respiratory therapies, stratified by BPD severity, were determined. RESULTS: Among 24 896 infants, 2574 (10.3%) died before 36 weeks' postmenstrual age (PMA), 12 198 (49.0%) did not develop BPD, 9192 (36.9%) developed grade 1 or 2 BPD, and 932 (3.7%) developed grade 3 BPD. Rates of mortality before 36 weeks' PMA and grade 3 BPD decreased from 52.7% and 9.9%, respectively, among infants born at 22 weeks' gestation to 17.3% and 0.8% among infants born at 29 weeks' gestation. Grade 1 or 2 BPD peaked in incidence (51.8%) among infants born at 25 weeks' gestation. The frequency of severe intraventricular hemorrhage or cystic periventricular leukomalacia increased from 4.8% among survivors without BPD to 23.4% among survivors with grade 3 BPD. Similar ranges were observed for late onset sepsis (4.8%-31.4%), surgically treated necrotizing enterocolitis (1.4%-17.1%), severe retinopathy of prematurity (1.2%-23.0%), and home oxygen therapy (2.0%-67.5%). CONCLUSIONS: More than one-half of very preterm infants born in the United States died before 36 weeks' PMA or developed BPD. Greater BPD severity was associated with more frequent development of major neonatal morbidities, in-hospital mortality, and use of supplemental respiratory support at discharge.

Treatment of a self-inflicted intracranial nail gun injury.

A 30-year-old man walked into the emergency department after a suicide attempt by firing a nail from a pneumatic nail gun directed at his left temple. He was haemodynamically stable and neurologically intact, able to recall all events and moving all extremities with a Glascow Coma Scale of 15. CT of the brain showed a 6.3 cm nail in the right frontal region without major intracerebral vessel disruption. He was taken to the operating room for left temporal wound washout, debridement of gross contamination and closure with titanium cranial fixation plate. The foreign body was not accessible on initial surgical intervention and was left in place to define anatomy and plan for subsequent removal. Thin slice CT images were used to create 3D reconstructions to facilitate stereotactic navigation and foreign body removal via right craniotomy the following day. The patient tolerated the procedures well and recovered with full neurological function.

An Evaluation to Establish the Acceptable Serum Triglyceride Levels in Neonates Receiving Intravenous Fat Emulsion Infusion in a Multicenter Retrospective Study.

OBJECTIVE: This study aimed to establish neonatal serum triglyceride (TG) level reference ranges during lipid infusion and correlate peak TG with neonatal outcomes. STUDY DESIGN: This is a retrospective review of 356 neonates with 696 TG measures obtained in four neonatal intensive care units between 2015 and 2017. TG was evaluated collectively to establish a reference range and a threshold limit. To analyze the effects of a higher TG threshold, neonates were categorized by their peak TG: <180 (TG<180), 180 to 400 (TG180-400), and > 400 mg/dL (TG>400). Univariable and multivariable regression models were constructed to compare peak TG to patient characteristic and clinical outcomes. RESULTS: The frequency of TG > 400 mg/dL was 5% and found only in neonates weighing < 1.5 kg. Neonates in the TG180-400 (n = 91) group were significantly lower in birth weight and gestational age, had lower 5-minute APGAR scores, and had increased ventilatory requirement when compared with neonates in the TG<180 (n = 240) group (all p < 0.001). The TG180-400 group had increased risk of severe intraventricular hemorrhage (p = 0.02) and bronchopulmonary dysplasia (p = 0.03). Elevated TG was associated with mortality (odds ratio [OR]: 14.4, p < 0.001) in univariable analysis, but the relationship weakened (OR: 4.4, p = 0.05) after adjusting for comorbidities in multivariable logistic regression. CONCLUSION: It is unclear if the adverse outcomes seen in neonates with higher peak TG were due to elevated TG alone, or whether illness severity predicted the increased TG. More prospective studies are needed to further delineate the relationships.

Assessing haemorrhage-critical values of cerebral blood flow by modelling biomechanical stresses on capillaries in the immature brain.

The development of intraventricular haemorrhages (IVH) in preterm newborns is triggered by a disruption of the vessels responsible for cerebral microcirculation. Analysis of the stresses exerted on vessel walls enables the identification of the critical values of cerebral blood flow (CBF) associated with the development of IVH in preterm infants. The purpose of the present study is the estimation of these critical CBF values using the biomechanical stresses obtained by the finite element modelling of immature brain capillaries. The properties of the endothelial cells and basement membranes employed were selected on the basis of published nanoindentation measurements using atomic force microscopes. The forces acting on individual capillaries were derived with a mathematical model that accounts for the peculiarities of microvascularity in the immature brain. Calculations were based on clinical measurements obtained from 254 preterm infants with the gestational age ranging from 23 to 30 weeks, with and without diagnosis of IVH. No distinction between the affected and control groups with the gestational age of 23 to 26 weeks was possible. For infants with the gestational age of 27 to 30 weeks, the CBF value of 17.03 ml/100 g/min was determined as the critical upper value, above which the likelihood of IVH increases.

Head midline position for preventing the occurrence or extension of germinal matrix-intraventricular haemorrhage in preterm infants.

BACKGROUND: Head position during care may affect cerebral haemodynamics and contribute to the development of germinal matrix-intraventricular haemorrhage (GM-IVH) in very preterm infants. Turning the head toward one side may occlude jugular venous drainage while increasing intracranial pressure and cerebral blood volume. It is suggested that cerebral venous pressure is reduced and hydrostatic brain drainage improved if the infant is cared for in the supine 'head midline' position. OBJECTIVES: To assess whether head midline position is more effective than other head positions for preventing (or preventing extension) of GM-IVH in very preterm infants (< 32 weeks' gestation at birth). SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 9), MEDLINE via PubMed (1966 to 12 September 2019), Embase (1980 to 12 September 2019), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 12 September 2019). We searched clinical trials databases, conference proceedings, and reference lists of retrieved articles. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing caring for very preterm infants in a supine head midline position versus a prone or lateral decubitus position, or undertaking a strategy of regular position change, or having no prespecified position. We included trials enrolling infants with existing GM-IVH and planned to assess extension of haemorrhage in a subgroup of infants. We planned to analyse horizontal (flat) versus head elevated positions separately for all body positions. DATA COLLECTION AND ANALYSIS: We used standard methods of Cochrane Neonatal. For each of the included trials, two review authors independently extracted data and assessed risk of bias. The primary outcomes were GM-IVH, severe IVH, and neonatal death. We evaluated treatment effects using a fixed-effect model with risk ratio (RR) for categorical data; and mean, standard deviation (SD), and mean difference (MD) for continuous data. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: Three RCTs, with a total of 290 infants (either < 30 weeks' gestational age or < 1000 g body weight), met the inclusion criteria. Two trials compared supine midline head position versus head rotated 90° with the cot flat. One trial compared supine midline head position versus head rotated 90° with the bed tilted at 30°. We found no trials that compared supine versus prone midline head position. Meta-analysis of three trials (290 infants) did not show an effect on rates of GM-IVH (RR 1.11, 95% confidence interval (CI) 0.78 to 1.56; I² = 0%) and severe IVH (RR 0.71, 95% CI 0.37 to 1.33; I² = 0%). Neonatal mortality (RR 0.49, 95% CI 0.25 to 0.93; I² = 0%; RD -0.09, 95% CI -0.16 to -0.01) and mortality until hospital discharge (typical RR 0.50, 95% CI 0.28 to 0.90; I² = 0%; RD -0.10, 95% CI -0.18 to -0.02) were lower in the supine midline head position. The certainty of the evidence was very low for all outcomes because of limitations in study design and imprecision of estimates. We identified one ongoing study. AUTHORS' CONCLUSIONS: We found few trial data on the effects of head midline position on GM-IVH in very preterm infants. Although meta-analyses suggest that mortality might be reduced, the certainty of the evidence is very low and it is unclear whether any effect is due to cot tilting (a co-intervention in one trial). Further high-quality RCTs would be needed to resolve this uncertainty.

Unusual Periventricular Hemorrhage as the Initial Manifestation of Central Nervous System Tuberculosis.

BACKGROUND: Intracranial hemorrhage (ICH) is a rare complication of central nervous system (CNS) tuberculosis, and intratuberculoma hemorrhage is even more rare. To the best of our knowledge, periventricular hemorrhage caused by CNS tuberculosis has not yet been reported. In the present report, we have described the peculiar neuroradiological manifestations of periventricular hemorrhage secondary to CNS tuberculosis and discussed the possible mechanisms of intratuberculoma hemorrhage supported by the neuroradiological findings. CASE DESCRIPTION: We have reported the case of a 50-year-old man who had presented with headache. The initial computed tomography (CT) scan had shown periventricular hematoma with intraventricular hemorrhage. Despite conventional treatment of ICH, his headache deteriorated and repeated CT scan revealed expansion of the hematoma. Further investigation demonstrated CNS tuberculosis and tuberculomas lying within the periventricular hematoma. CONCLUSIONS: ICH can present as the initial manifestation of CNS tuberculosis, and CNS tuberculosis should be suspected when hemorrhage has occurred at an unusual site or the hematoma has expanded despite conventional treatment.

The slice score: A novel scale measuring intraventricular hemorrhage severity and predicting poor outcome following intracerebral hemorrhage.

OBJECTIVES: To quantify extent of intraventricular hemorrhage (IVH) following intracerebral hemorrhage (ICH) with a novel, simple IVH severity score, and to explore and compare its performance in predicting worse outcomes. PATIENTS AND METHODS: A new scoring system for IVH severity was proposed and termed Slice score. The Slice score features non-septum pellucidum section, internal capsule section, third ventricle occipital horn section, three standardized scans for scoring the lateral ventricles. 652 scans from 326 subjects were retrospectively analyzed. The correlations between measured IVH volume and Slice score, original Graeb, LeRoux, and IVH score (IVHS) were compared. The association between these scores and clinical outcomes were evaluated using logistic regression. We then identified clinical thresholds of Slice score by balancing the probability of prediction and accuracy. Primary outcome was defined as 90-day poor outcome (modified Rankin Scale score ≥ 4) and secondary outcome was 90-day mortality. RESULTS: Of 326 ICH patients, 122 (37.4%) had poor outcome and 59 (18.1%) died at 3 months. The Slice score showed the highest correlation with measured IVH volume (R = 0.73, R2 = 0.54, p < 0.001). The observed area under the curve were similar among the Slice, original Graeb, LeRoux score, and IVH score for poor outcome (0.633, 0.633, 0.632, 0.634, respectively), and for mortality (0.660, 0.660, 0.660, 0.656, respectively). All IVH scales were independently associated with 90-day poor outcome and mortality with close odds ratio in adjusted models (all odds ratio > 1.07, all p < 0.05). Multivariable Analyses of categorized Slice score revealed optimal thresholds of 6 and 12 for primary and secondary outcomes (odds ratio 4.20, 95% confidence interval 1.82-10.02, p = 0.001; odds ratio 5.41, 95% confidence interval 1.66-17.43, p = 0.005, respectively). CONCLUSIONS: The Slice score correlated highly with the IVH volume, was a reliable volumetric scale for measuring IVH severity, and could be an easy-to-use tool for predicting 90-day poor outcome and mortality in ICH.

Early Cardiac and Cerebral Hemodynamics with Umbilical Cord Milking Compared with Delayed Cord Clamping in Infants Born Preterm.

OBJECTIVE: To evaluate changes in cerebral oxygenation, peripheral arterial oxygenation, respiratory status, and administered fraction of inspired oxygen during the first 10 minutes of life in premature infants receiving umbilical cord milking compared with delayed cord clamping (DCC). STUDY DESIGN: Premature infants born at 230/7 to 276/7 weeks of gestation were randomized to umbilical cord milking or DCC. A near infrared spectroscopy sensor, pulse oximeter, and electrocardiogram electrodes were placed. Pulse rate, cerebral tissue oxygenation, peripheral oxygen saturation, airway pressure, and fraction of inspired oxygen were collected for 10 minutes in the delivery room. Longitudinal models were used to compare effects of umbilical cord milking and DCC. RESULTS: Fifty-six infants had cerebral oximetry and advanced monitoring at birth. There was an increased incidence of severe intraventricular hemorrhage in infants who received umbilical cord milking compared with DCC (P = .0211). Longitudinal models suggested that peripheral oxygen saturation was higher in the umbilical cord milking group in the first 4 minutes (P = .0221) and that mean airway pressures were lower in the umbilical cord milking group after the first 7 minutes (P = .0072). No statistical differences were observed for fraction of inspired oxygen, cerebral tissue oxygenation, or heart rates. CONCLUSIONS: The data suggest that the rapid transfer of blood during umbilical cord milking may facilitate lung expansion with improved pulmonary blood flow, but may also increase cerebral blood flow, resulting in severe intraventricular hemorrhage. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03145142.

Antenatal corticosteroids and preterm offspring outcomes in hypertensive disorders of pregnancy: A Japanese cohort study.

To estimate whether antenatal corticosteroids (ACS) improve short- and long-term preterm offspring outcomes in singleton pregnancies complicated by hypertensive disorders of pregnancy (HDP) similar to pregnancies without HDP. This population-based retrospective study was conducted based on an analysis of data collected by the Neonatal Research Network of Japan on 21,014 singleton neonates weighing ≤1,500 g between 24 and 31 weeks' gestation during 2003-2016. Logistic regression analyses were performed to compare short- and long-term offspring outcomes between mothers receiving ACS treatment and those who did not among pregnancies with HDP and without HDP. Of 21,014 neonates, 4,806 (22.9%) were born to mothers with HDP. ACS treatment was associated with significant decreases in short-term adverse outcomes in the both HDP and non-HDP groups, with similar reduced odds of neonatal death, respiratory distress syndrome, and intraventricular haemorrhage (IVH). However, ACS treatment did not significantly decrease severe IVH (aOR 0.76; 95% CI 0.51-1.13) and periventricular leukomalacia (1.14; 0.78-1.66) in the HDP group. In addition, ACS treatment in mothers without HDP significantly decreased cerebral palsy (aOR 0.70; 95% CI 0.58-084), developmental quotient scores <85 (0.79; 0.69-0.90), and composite adverse outcomes (0.85; 0.75-0.96) at 3 years of age, whereas ACS treatment in mothers with HDP did not significantly improve these outcomes (1.04; 0.69-1.57, 1.11; 0.88-1.39, 0.96; 0.75-1.22, respectively). ACS treatment was associated with significantly decreased major short-term morbidities and mortality among extremely and very preterm neonates of mothers with HDP, with ACS treatment having a decreased effect compared to that observed in neonates of mothers without HDP. Although ACS treatment has no additional effects on offspring outcomes at 3 years of age, our results did not suggest that ACS treatment should be withheld from mothers with HDP.

Granular Cell Tumor of the Pituitary Presenting with Major Intraventricular Hemorrhage.

Granular cell tumors of the pituitary gland are rare, slow-growing lesions arising from the neurohypophysis or pituitary stalk. We describe an extremely rare presentation of a pituitary granular cell tumor mimicking an anterior communicating artery aneurysmal rupture with ventricular hemorrhage. The patient was admitted in a comatose state and underwent urgent bilateral external ventricular drainage. Further diagnostic investigation revealed a sellar tumoral mass with suprasellar extension. No vascular anomalies, hormonal abnormalities, or visual disturbances were observed. Macroscopic complete resection without neurologic impairment was obtained via a right pterional approach. Posthemorrhagic hydrocephalus necessitated ventriculoperitoneal shunt placement, and hormonal substitution for panhypopituitarism was provided. The 5-year follow-up examination showed no tumor recurrence. The clinical course of these benign World Health Organization grade I lesions will normally correspond to nonsecreting pituitary adenomas with an insidious development of visual disturbances, hypopituitarism, or hydrocephalus. Sudden onset with potential catastrophic intratumoral and intraventricular hemorrhage is very uncommon.
