BACKGROUND
Rapid delivery is important in cases of umbilical cord prolapse to prevent hypoxic injury to the fetus/neonate. However, the optimal decision-to-delivery interval remains controversial.
OBJECTIVE
The aim of the study was to investigate the association between the decision-to-delivery interval in women with umbilical cord prolapse, stratified by fetal heart rate pattern at diagnosis, and neonatal outcome.
STUDY DESIGN
The database of a tertiary medical center was retrospectively searched for all cases of intrapartum cord prolapse between 2008 and 2021. The cohort was divided into three groups according to findings on the fetal heart tracing at diagnosis: 1) bradycardia; 2) decelerations without bradycardia; and 3) reassuring heart rate. The primary outcome measure was fetal acidosis. The correlation between cord blood indices and decision-to-delivery interval was analyzed using Spearman's rank correlation coefficient.
RESULTS
Of the total 103,917 deliveries performed during the study period, 130 (0.13%) were complicated by intrapartum umbilical cord prolapse. Division by fetal heart tracing yielded 22 women (16.92%) in group 1, 41 (31.53%) in group 2, and 67 (51.53%) in group 3. The median decision-to-delivery interval was 11.0 min (IQR 9.0-15.0); the interval was more than 20 min in 4 cases. The median cord arterial blood pH was 7.28 (IQR 7.24-7.32); pH was less than 7.2 in 4 neonates. There was no correlation of cord arterial pH with decision-to-delivery interval (Spearman's Ρ = - 0.113; Ρ = 0.368) or with fetal heart rate pattern (Spearman's Ρ = .425; Ρ = .079, Ρ = - .205; Ρ = .336, Ρ = - .324; Ρ = .122 for groups 1-3, respectively).
CONCLUSION
Intrapartum umbilical cord prolapse is a relatively rare obstetric emergency with an overall favorable neonatal outcome if managed in a timely manner, regardless of the immediately preceding fetal heart rate. In a clinical setting which includes a high obstetric volume and a rapid, protocol-based, response, there is apparently no significant correlation between decision-to-delivery interval and cord arterial cord pH.

Review
Any acute and profound reduction in fetal oxygenation increases the risk of anaerobic metabolism in the fetal myocardium and, hence, the risk of lactic acidosis. On the contrary, in a gradually evolving hypoxic stress, there is sufficient time to mount a catecholamine-mediated increase in the fetal heart rate to increase the cardiac output and redistribute oxygenated blood to maintain an aerobic metabolism in the fetal central organs. When the hypoxic stress is sudden, profound, and sustained, it is not possible to continue to maintain central organ perfusion by peripheral vasoconstriction and centralization. In case of acute deprivation of oxygen, the immediate chemoreflex response via the vagus nerve helps reduce fetal myocardial workload by a sudden drop of the baseline fetal heart rate. If this drop in the fetal heart rate continues for >2 minutes (American College of Obstetricians and Gynecologists' guideline) or 3 minutes (National Institute for Health and Care Excellence or physiological guideline), it is termed a prolonged deceleration, which occurs because of myocardial hypoxia, after the initial chemoreflex. The revised International Federation of Gynecology and Obstetrics guideline (2015) considers the prolonged deceleration to be a "pathologic" feature after 5 minutes. Acute intrapartum accidents (placental abruption, umbilical cord prolapse, and uterine rupture) should be excluded immediately, and if they are present, an urgent birth should be accomplished. If a reversible cause is found (maternal hypotension, uterine hypertonus or hyperstimulation, and sustained umbilical cord compression), immediate conservative measures (also called intrauterine fetal resuscitation) should be undertaken to reverse the underlying cause. In reversible causes of acute hypoxia, if the fetal heart rate variability is normal before the onset of deceleration, and normal within the first 3 minutes of the prolonged deceleration, then there is an increased likelihood of recovery of the fetal heart rate to its antecedent baseline within 9 minutes with the reversal of the underlying cause of acute and profound reduction in fetal oxygenation. The continuation of the prolonged deceleration for >10 minutes is termed "terminal bradycardia," and this increases the risk of hypoxic-ischemic injury to the deep gray matter of the brain (the thalami and the basal ganglia), predisposing to dyskinetic cerebral palsy. Therefore, any acute fetal hypoxia, which manifests as a prolonged deceleration on the fetal heart rate tracing, should be considered an intrapartum emergency requiring an immediate intervention to optimize perinatal outcome. In uterine hypertonus or hyperstimulation, if the prolonged deceleration persists despite stopping the uterotonic agent, then acute tocolysis is recommended to rapidly restore fetal oxygenation. Regular clinical audit of the management of acute hypoxia, including the "the onset of bradycardia to delivery interval," may help identify organizational and system issues, which may contribute to poor perinatal outcomes.

BACKGROUND
Anorectal malformations (ARM) are associated with neurogenic bladder. The traditional surgical ARM repair is a posterior sagittal anorectoplasty (PSARP), which is believed to have a minimal effect on bladder dynamics. However, little is known about the effects of reoperative PSARP (rPSARP) on bladder function. We hypothesized that a high rate of bladder dysfunction existed in this cohort.
METHODS
We performed a retrospective review of ARM patients undergoing rPSARP at a single institution from 2008 to 2015. Only patients with Urology follow-up were included in our analysis. Data was collected regarding original level of ARM, coexisting spinal anomalies and indications for reoperation. We assessed urodynamic variables and bladder management (voiding, CIC or diverted) before and after rPSARP.
RESULTS
A total of 172 patients were identified, of which 85 met inclusion criteria with a median follow-up of 23.9 months (IQR, 5.9-43.8 months). Thirty-six patients had spinal cord anomalies. Indications for rPSARP included mislocation (n = 42), posterior urethral diverticulum (PUD; n = 16), stricture (n = 19) and rectal prolapse (n = 8). Within 1 year following rPSARP, 11 patients (12.9%) had a negative change in bladder management, defined as need for beginning intermittent catheterization or undergoing urinary diversion, which increased to 16 patients (18.8%) at last follow-up. Postoperative bladder management changed in rPSARP patients with mislocation (p < 0.0001) and stricture (p 0.005) but not for rectal prolapse (p 0.143).
CONCLUSIONS
Patients who undergo rPSARP warrant especially close attention for bladder dysfunction as we observed a negative postoperative change in bladder management in 18.8% of our series.

Observational Study
Background Intrauterine fetal death (IUFD) is a demise occurring at 20 or more weeks of gestation and weight 500 gram or more. Intrauterine fetal death at any point during gestation is a traumatic event not only to the patient but also to the care giver. The purpose of this study is to know the risk factors associated with intrauterine fetal death. Objective To determine the factors associated with intrauterine fetal death. Method Prospective observational study was conducted at Paropkar maternity women's hospital, Thapathali, Kathmandu. All the cases with intrauterine fetal death were admitted and delivered in the hospital with period of gestation 20 weeks to term pregnancy. All the relevant data were recorded in pre-designed proforma. The collected data were entered in SPSS 25 version for analysis. Result There was a total 5153 deliveries in three months, with prevalence of 1.2% and intrauterine rate of 12.03 per 1000 births. Out of 50 enrolled cases, 78% (n=50) of patient had not attended antenatal checkup. Majority (n=50; 74%), belonged to age group 21-35 years, 48% of intrauterine fetal death were term pregnancies of 37 to 42 weeks of gestation. Maximum 20% of IUFD, weighed between (1-1.5 kg) (1.5-2 kg) and (2.5-3 kg). Thirty-nine babies were macerated and eleven non-macerated. Pregnancy induced hypertension was most common (26%), followed by ante-partum hemorrhage (8%), hypothyroidism and anemia (6%), meconium stained liquor and cord prolapse (6%), gestational diabetes mellitus, congenital anomalies, chronic hypertension (4%), intrauterine growth restriction and urinary tract infection (2%). Twelve cases underwent cesarean section. Postpartum complications were found in 10 cases; 4 cases had postpartum hemorrhage, 4 had prolonged hospital stay and 2 cases developed hemolysis, elevated liver enzyme, low platelet count (HELLP) syndrome. Conclusion This study concluded that maximum no. of intrauterine fetal death were seen antenatally, as 78% of cases were found macerated. The commonest identified risk factor was pregnancy induced hypertension, followed by ante-partum hemorrhage, anemia, hypothyroidism, which seem to be preventable risk factors of intrauterine fetal death, but still unidentified risk factors are of great challenges for the obstetricians.

INTRODUCTION
In this case report, we question the safety associated with high velocity manipulations of the cervical spine. These procedures do not frequently cause catastrophic adverse effects but few and rare case reports like this make us aware about the possible complications of the maneuvers.
CASE REPORT
This case report presents an uncommon presentation of acute neurodeficit to a 57-year-old male following a neck manipulation by a barber in the saloon which recovered partially with Intravenous steroid therapy but required active intervention surgically to treat his complete symptomatology. The magnetic resonance imaging (T2-weighted) showed a high signal intensity within the spinal cord at the C4C5 level (cord edema). Here, we discuss the possible mechanism of injury and the need to educate the lesser common risks of performing such sudden and forceful maneuvers.
CONCLUSION
This case report is a reminder that people should be careful while trying alterative types of therapy which use forceful neck manipulations to relieve pain as this maneuver could cause injuries to the disc complex especially when the patient already has a disc prolapse which is asymptomatic, causing the disc to fail again making it symptomatic.

Mucopolysaccharidosis (MPS) is a hereditary disorder arising from lysosomal enzymes deficiency, with glycosaminoglycans (GAGs) storage in connective tissues and bones, which may compromise the airway. This retrospective study evaluated patients with MPS type IVA with airway obstruction detected via endoscopy and imaging modalities and the effects of surgical interventions based on symptoms. The data of 15 MPS type IVA patients (10 males, 5 females, mean age 17.8 years) were reviewed in detail. Fiberoptic bronchoscopy (FB) was used to distinguish adenotonsillar hypertrophy, prolapsed soft palate, secondary laryngomalacia, vocal cord granulation, cricoid thickness, tracheal stenosis, shape of tracheal lumen, nodular deposition, tracheal kinking, tracheomalacia with rigid tracheal wall, and bronchial collapse. Computed tomography (CT) helped to measure the deformed sternal angle, the cross-sectional area of the trachea, and its narrowest/widest ratio (NW ratio), while angiography with 3D reconstruction delineated tracheal torsion, kinking, or framework damage and external vascular compression of the trachea. The NW ratio correlated negatively with age ( < 0.01), showing that airway obstruction progressed gradually. Various types of airway surgery were performed to correct the respiratory dysfunction. MPS type IVA challenges the management of multifactorial airway obstruction. Preoperative airway evaluation with both FB and CT is strongly suggested to assess both intraluminal and extraluminal factors causing airway obstruction.

Review
BACKGROUND
Robert's uterus is a rare congenital anomaly, characterized as an asymmetric septate uterus that has a blind hemicavity with unilateral menstrual fluid retention and a unicornuate hemicavity connecting to the cervix unimpededly. Patients with Robert's uterus generally present with menstrual disorders and dysmenorrhea, and some may have reproductive problems as well, including infertility, recurrent miscarriage, preterm labor and obstetric complications. In this case, we describe a successful pregnancy implanted on the obstructed hemicavity and delivered a liveborn girl. Meanwhile, we highlight diagnostic and therapeutic difficulties in patients with atypical symptoms of Robert's uterus.
CASE PRESENTATION
A 30-year-old Chinese primigravida sought for emergency treatment at 26 weeks and 2 days of gestation because of preterm premature rupture of membranes (PPROM). At the age of 19, the patient was misdiagnosed with hyperprolactinemia and pituitary microadenoma for showing symptom of hypomenorrhea and was suspected to have a uterine septum in the first trimester. She was diagnosed with Robert's uterus at 22 weeks of gestation by repetitious prenatal transvaginal ultrasonography, which was subsequently confirmed by magnetic resonance imaging. At 26 weeks and 3 days of gestation, the patient was suspected to have oligohydramnion, irregular uterine contraction, and umbilical cord prolapse, and she expressed a strong will of saving the baby. Emergency cesarean delivery was performed and a small hole, together with several weak spots, was found at the lower and back wall of the septum of the patient. The treatment was effective and both the mother and the infant, who had an extremely low birth weight, were discharged in good health conditions.
CONCLUSIONS
Pregnancy in the blind cavity of Robert's uterus with living neonates is incredibly rare. In our case, the favorable outcome may result from the unusual hole found at the septum, which may play a role in communicating amniotic fluid between the two hemicavities so to keep the neonate alive. we highlight the importance of early diagnosis and pre-pregnancy treatment of this uterine malformation, and the timely termination of pregnancy, for improving birth quality and reducing mortality.

BACKGROUND
Neonatal hypoxic ischaemic encephalopathy (HIE) is the most common cause of encephalopathy in the neonatal period and carries a high risk of mortality and long-term morbidity.
AIM
The aim of this study was to investigate key antecedents of moderate and severe HIE in a large contemporary birth cohort.
METHODS
A retrospective cohort study of births meeting criteria was conducted between 2016 and 2020 at the Mater Mothers' Hospital, Brisbane, Australia. This is a quaternary perinatal centre and Australia's largest maternity hospital. Univariate and multivariate Firth logistic regression were used to account for imbalanced frequency classes between non-HIE and HIE groups. Maternal variables and intrapartum factors were investigated for associations with neonatal moderate and severe HIE.
RESULTS
Overall, 133 of 46 041 (0.29%) infants were diagnosed with HIE: 77 (0.17%) with mild HIE and 56 (0.12%) with moderate/severe HIE. Nulliparity, type 1 diabetes mellitus and maternal intensive care unit admission were associated with increased odds of moderate/severe HIE. Intrapartum risk factors included emergency caesarean birth, emergency caesarean for non-reassuring fetal status or failure to process, intrapartum haemorrhage and an intrapartum sentinel event (shoulder dystocia, cord prolapse, uterine rupture and placental abruption). Neonatal risk factors included male sex, late preterm gestation (35 -36 weeks), Apgar score less than four at 5 min, severe respiratory distress requiring ventilatory support and severe acidosis at birth.
CONCLUSIONS
This cohort study identified a series of potentially modifiable maternal and obstetric risk factors for HIE. Risk factors for HIE do not appear to have changed significantly with evolution in modern obstetric care.

Lumbar disc herniation (LDH) is prevalent among adults aged 25-55 years who spend a considerable proportion of their time sitting or standing with heavy workloads. We report the case of a 33-year-old male waiter with severe LDH, causing compression of the nerve roots and spinal cord with neurological dysfunction, who presented to a chiropractic clinic. Magnetic resonance imaging (MRI) revealed a radiological differential diagnosis comprising LDH and an epidural mass lesion. To rule out serious pathology, a second MRI with contrast was ordered, which confirmed the diagnosis of severe LDH. Diagnosing large LDH may be challenging, and severe disc herniation often mimics spinal tumors. This study offers insights into the differential diagnosis of LDH and spinal tumors, as well as the design of a treatment strategy for severe LDH in the chiropractic clinic.
