The atypical hemolytic uremic syndrome (aHUS) in the newborn is a rare disease, with high morbidity. Eculizumab, considered a first-line drug in older children, is not approved in neonates and in children weighing less than 5 kg. We present a 5-day-old female newborn, born at 36 weeks' twin gestation, by emergency cesarean section due to cord prolapse, with birth weight of 2,035 g and Apgar score of 7/7/7, who develops microangiopathic hemolytic anemia, thrombocytopenia, and progressive acute renal failure. In day 5, after diagnosis of aHUS, a daily infusion of fresh frozen plasma begins, with improvement of thrombocytopenia and very slight improvement in renal function. The etiologic study (congenital infection, Shiga toxin, ADAMTS13 activity, directed metabolic study) was normal. C3c was slightly decreased. On day 16 for maintenance of anemia and severe renal failure, she started 300 mg/dose eculizumab. Anemia resolves in 10 weeks and creatinine has normal values after 13 weeks of treatment. The genetic study was normal. In this case, eculizumab is effective in controlling microangiopathy and in the recovery of renal function. Diagnosis of neonatal aHUS can be challenging because of phenotypic heterogeneity and potential overlap with other manifestations that may confound it, such as perinatal asphyxia or sepsis/disseminated intravascular coagulation.

OBJECTIVE
Minimally invasive spine surgery is rapidly gaining popularity because of its versatile nature. Traditionally, prolapsed disc has been the most common disease targeted using this technique. However, its usefulness for various other diseases has also been shown in studies. We present our experience of using this technique for various spinal diseases apart from prolapsed discs.
METHODS
This is a retrospective study in which patients operated on by a single surgeon from January 2019 to April 2023 were included. Cases that required conversion to open technique were excluded. Intraoperative findings and postoperative courses were obtained from patient records.
RESULTS
A total of 47 patients were included in the study, of whom 29 were male and 18 were female. The various diseases treated comprised intradural extramedullary (IDEM) tumors (n = 23), hypertrophied/ossified ligamentum flavum (n = 9), arachnoid cysts (n = 6), dermoid/epidermoid cysts (n = 4), detethering of cord (n = 3), and posterior cervical decompression for an ossified posterior longitudinal ligament (n = 2). The average duration of surgery was 2.1 ± 1.2 hours and the mean intraoperative blood loss was 138.4 ± 59.1 mL. The mean length of hospital stay was 2.3 ± 0.9 days. Two patients had superficial wound infection and none of the operated patients had cerebrospinal fluid leakage. Re-exploration was not required in any of the operated patients.
CONCLUSIONS
Minimally invasive techniques for dealing with multiple diseases involving the spine are as good as traditional open techniques, with some additional advantages of lesser tissue trauma, early return to work, and so on. However, one must overcome the steep learning curve before adopting them in day-to-day practice.

Global Spine Journal Sep 2020Retrospective observational study.
STUDY DESIGN
Retrospective observational study.
OBJECTIVES
Thoracic disc prolapse (TDP) surgeries have reported complications ranging from paraplegia to approach related complications. This study is to present a series of TDP patients surgically treated with transforaminal thoracic interbody fusion (TTIF). Emphasis on surgical technique and strategies to avoid complications are analyzed.
METHODS
Eighteen patients with TDP were included. Imagings were analyzed for end-plate changes and calcification. Type of disc prolapse (central/para-central) and percentage of canal occupancy were noted. Objective outcome was quantified with Visual Analogue Scale (VAS), modified Nurick's grade, and ASIA (American Spinal Injury Association) score. All complications were noted.
RESULTS
Eighteen patients (average age 43.65 years) having total 22 levels operated, that included double level (n = 2) and missed level (n = 2) are reported. All patients had myelopathy. Calcification of disc (n = 13), central disc prolapses (n = 9), para-central (n = 11) and more than 50% canal occupancy (n = 8) were noted. VAS back pain, modified Nurick's grade and ASIA grade improved significantly in all patients. One patient had postoperative transient deficit. The functional score achieved its maximum at 1 year follow-up and remained static at final follow-up of 65.05 months. Union was achieved in all patients.
CONCLUSIONS
The most important factor for outcome in TDP is the technical aspect of avoiding cord manhandling and avoiding wrong level surgeries. TTIF is not devoid of complications but can give good results to posterior approach trained surgeons.

BACKGROUND
Despite recent advances in perinatal care, neonatal hypoxic-ischemic encephalopathy remains one of the most common causes of neonatal morbidity and mortality. The trends for prevalence and mortality of neonatal hypoxic-ischemic encephalopathy have not been examined in the era of therapeutic hypothermia in the United States.
OBJECTIVE
This study aimed to determine (1) the overall and gestational age-specific (35-36, ≥37, and >42 weeks) trends of hypoxic-ischemic encephalopathy prevalence and use of therapeutic hypothermia, (2) the trends of mortality in association with hypoxic-ischemic encephalopathy, (3) the confounding variables associated with hypoxic-ischemic encephalopathy, and (4) the clinical outcomes of neonates with hypoxic-ischemic encephalopathy.
STUDY DESIGN
This study used National Inpatient Sample datasets from 2010 to 2018. Moreover, the study included infants with a gestational age of ≥35 weeks with a documented hypoxic-ischemic encephalopathy diagnosis (mild, moderate, severe, or unspecified). We calculated trends in hypoxic-ischemic encephalopathy prevalence and the use of therapeutic hypothermia using chi-squared testing. Furthermore, this study used logistic regression models to control for confounders.
RESULTS
A total of 32,180,617 infants were included, of which 31,249,100 were term (gestational age of ≥37 weeks) and 931,517 were late preterm (gestational age of 35-36 weeks). Hypoxic-ischemic encephalopathy prevalence slightly increased from 0.093% in 2010-2012 to 0.097% in 2016-2018 (P=.01) in term infants and did not significantly change in late preterm infants (P=.20). There were 6235 term infants (20.8%) and 449 late preterm infants (21.1%) with hypoxic-ischemic encephalopathy who were managed with therapeutic hypothermia. The use of therapeutic hypothermia in both term and late preterm infants has increased over the years (P<.01). The mortality rate with hypoxic-ischemic encephalopathy decreased over time from 11.5% to 12.3% between 2010 to 2012, and from 8.3% to 10.6% betweenn 2016 to 2018 (P<.01). The factors with the strongest association with hypoxic-ischemic encephalopathy were placental infarction or insufficiency (odds ratio, 144; 95% confidence interval, 134-157), placental abruption (odds ratio, 101; 95% confidence interval, 91-112), cord prolapse (odds ratio, 74; 95% confidence interval, 65-84), and maternal anemia (odds ratio, 26; 95% confidence interval, 20-37).
CONCLUSION
Hypoxic-ischemic encephalopathy prevalence in neonates essentially remained the same at 1 per 1000 live births. The use of therapeutic hypothermia increased, and the mortality rate decreased in infants with hypoxic-ischemic encephalopathy. The identification of hypoxic-ischemic encephalopathy-associated factors should promote increased vigilance to optimize newborn outcomes.

BACKGROUND
To this date, there are 4 systematic reviews and meta-analyses studies about the burden and associated factors of birth asphyxia in Ethiopia. However, findings of these studies are inconsistent which is difficult to make use of the findings for preventing birth asphyxia in the country. Therefore, umbrella review of these studies is required to pool the inconsistent findings into a single summary estimate that can be easily referred by the information users in Ethiopia.
METHODS
PubMed, Science direct, web of science, data bases specific to systematic reviews such as the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects were searched for systematic reviews and meta-analyses (SRM) studies on the magnitude and risk factors of perinatal asphyxia in Ethiopia. The methodological quality of the included studies was assessed using the Assessment of Multiple Systematic Reviews (AMSTAR) tool. The estimates of the included SRM studies on the prevalence and predictors of perinatal asphyxia were pooled and summarized with random-effects meta-analysis models. From checking PROSPERO, this umbrella review wasn't registered.
RESULTS
We included four SRM studies with a total of 49,417 neonates. The summary estimate for prevalence of birth asphyxia was 22.52% (95% CI = 17.01%-28.02%; I = 0.00). From the umbrella review, the reported factors of statistical significance include: maternal illiteracy [AOR = 1.96; 95% CI: 1.44-2.67], primiparity [AOR = 1.29; 95% CI: 1.03-1.62], antepartum hemorrhage [AOR = 3.43; 95% CI: 1.74-6.77], pregnancy induced hypertension [AOR = 4.35; 95% CI: 2.98-6.36], premature rupture of membrane [AOR = 12.27; 95% CI: 2.41, 62.38], prolonged labor [AOR = 3.18; 95% CI: 2.75, 3.60], meconium-stained amniotic fluid [AOR = 5.94; 95% CI: 4.86, 7.03], instrumental delivery [AOR = 3.39; 95% CI: 2.46, 4.32], non-cephalic presentation [AOR = 3.39; 95% CI: 1.53, 5.26], cord prolapse [AOR = 2.95; 95% CI: 1.64, 5.30], labor induction [AOR = 3.69; 95% CI: 2.26-6.01], cesarean section delivery [AOR = 3.62; 95% CI: 3.36, 3.88], low birth weight [AOR = 6.06; 95% CI: 5.13, 6.98] and prematurity [AOR = 3.94; 95% CI: 3.67, 4.21] at 95% CI.
CONCLUSION
This umbrella review revealed high burden of birth asphyxia in Ethiopia. The study also indicated significant risk of birth asphyxia among mothers who were unable to read and write, primiparous mothers, those mothers having antepartum hemorrhage, pregnancy induced hypertension, premature rupture of membrane, prolonged labor, meconium-stained amniotic fluid, instrumental delivery, cesarean section delivery, non-cephalic presentation, cord prolapse and labor induction. Moreover, low birth weight and premature neonates were more vulnerable to birth asphyxia compared to their normal birth weight and term counterparts. Therefore, burden of birth asphyxia should be mitigated through special consideration of these risk mothers and neonates during antenatal care, labor and delivery. Mitigation of the problem demands the collaborative efforts of national, regional and local stakeholders of maternal and neonatal health.

Saccular limited dorsal myeloschisis (LDM) is characterized by a fibroneural stalk linking the saccular skin lesion to the underlying spinal cord. Since untethering surgery during the early postnatal period is often indicated to prevent sac rupture, saccular LDM should be distinguished from myelomeningocele (MMC) during the perinatal period. We treated two patients with the spinal cord deviation from the spinal canal to the sac, which mimicked a prolapse of the neural placode into the MMC sac. In patient 1, pre- and postnatal magnetic resonance imaging (MRI) revealed that the spinal cord was strongly tethered to the thick stalk. During surgery, the dorsally bent cord and stalk were united, and the border between these two was determined with intraoperative neurophysiological mapping (IONM). In patient 2, the spinal cord was tethered to two slender stalks close to each other, which was visible with the combined use of sagittal and axial postnatal three-dimensional heavily T2-weighted imaging (3D-hT2WI). The preoperative MRI hallmark of saccular LDM is the visualization of a stalk that links the bending cord and sac. Complete untethering surgery to return the cord into the spinal canal and correct its dorsal bending is recommended.

Comparative Study
INTRODUCTION
Fetal bradycardia due to sentinel events such as placental abruption, cord prolapse or uterine rupture is associated with an increased risk of acidemia at birth. In the absence of a sentinel event, data regarding neonatal prognosis are scarce, and it seems plausible that the depth of bradycardia might be associated with an increased risk of acidosis at birth. The objective was to determine whether the depth of bradycardia is associated with a higher risk of umbilical artery acidemia at birth in term singleton pregnancies requiring cesarean delivery during labor.
MATERIAL AND METHODS
A retrospective comparative study of all cesarean deliveries for bradycardia in an academic tertiary center in the 6-year period of 2013-2018, among term singleton pregnancies. Bradycardia associated with a sentinel event such as placental abruption, cord prolapse or uterine rupture, were excluded. The nadir of the bradycardia was defined as the lowest fetal heart rate baseline lasting at least 3 minutes during bradycardia. Women who delivered an infant with an umbilical pH at birth <7.00 (acidosis group) were compared with women who delivered an infant with an umbilical pH at birth ≥7.00 (non-acidosis group).
RESULTS
Among 111 eligible cases, 32 women in the acidosis group were compared with 79 in the non-acidosis group. The median nadir of the bradycardia was lower in the acidosis than in the non-acidosis group (60 bpm, interquartile range [56-65] vs 70 [60-76], P < .01). A bradycardia nadir <60 bpm emerged as the optimal threshold for predicting acidemia and was more frequently observed in the acidosis than in the non-acidosis group (10 [31%] vs 10 [13%], P = .02). In the multivariable analysis, a nadir <60 bpm was independently associated with an umbilical artery pH <7.00 (adjusted OR 3.16, 95% CI 1.10-9.04).
CONCLUSIONS
A bradycardia nadir <60 bpm was associated with a tripled risk of umbilical artery acidemia at birth.

Randomized Controlled Trial
OBJECTIVES
To identify the perinatal risk factors for the occurrence of singleton apparently stillborn infants.
METHODS
This was a case-control study. A total of 154 singleton neonates with gestational age ≥28 weeks and Apgar score of 0-1 who were subsequently successfully resuscitated in the Obstetrics and Gynecology Hospital of Fudan University from January 2006 to December 2015 were enrolled as the case group (apparently stillborn group). A total of 616 singleton infants born from January 2006 to December 2015 (1-minute Apgar score >1) were randomly selected in a 1:4 ratio as the control group. Univariate analysis and multivariate logistic regression were used to analyze the perinatal risk factors for the occurrence of apparently stillborn infants.
RESULTS
The gestational age and birth weight in the apparently stillborn group were significantly lower than those in the control group (<0.05). The incidences of fetal hydrops, cord prolapse, grade III meconium-stained amniotic fluid, placental abruption, breech presentation, severe pre-eclampsia, maternal general anesthesia at delivery, abnormal antenatal fetal heart monitoring and decreased fetal movement were significantly higher in the apparently stillborn group than those in the control group (<0.05). The multivariate logistic analysis showed that the mother had general anesthesia at delivery (=34.520), decreased antenatal fetal movement (=28.168),placental abruption (=15.641), grade III meconium-stained amniotic fluid (=6.365), abnormal antenatal fetal heart monitoring (=5.739), and breech presentation (=2.614) were risk factors for the occurrence of apparently stillborn infants (<0.05), while higher gestational age was a protective factor (=0.686, <0.05).
CONCLUSIONS
Attention needs to be paid to mothers with abnormal prenatal fetal heart monitoring, decreased fetal movement, preterm labor, placental abruption, breech presentation, grade III meconium-stained amniotic fluid, and general anesthesia. Preparations for resuscitation should be done to rescue apparently stillborn infants.
