The effect of surgery time on prognosis in newborns with meningomyelocele

Clinical presentation and outcomes of neonates born with neural tube defects- an experience from a level III B NICU in Western India

PURPOSE

Neural tube defects (NTDs) are one of the most common congenital anomalies and a cause of chronic disability. The study was done to study outcomes of neural tube defects admitted at a tertiary level neonatal intensive care unit (NICU) from 2018 to 2022, a period of 4 years that also coincided with the COVID pandemic. The secondary outcome was to study the clinical presentation, associated anomalies and epidemiological features.

METHODS

It was a retrospective observational study; data of infants was obtained from medical records and analysis was done.

RESULTS

Thirty-four neonates were enrolled, of which there were 16 (47%) males and 18 (53%) females. History of pre-pregnancy maternal folate intake was present in 4 (11.7%) cases. 33 (97%) babies were diagnosed with meningomyelocele (MMC) and one each had anencephaly, iniencephaly and encephalocele, of which one had frontal and two had occipital encephalocele. The median age of surgery was 16 days of life with primary repair being the most common procedure followed by MMC repair with VP shunt. Twenty babies (58.8%) were discharged successfully, while 9 (26.5%) expired and 5 (14.7%) were discharged against medical advice; which can be attributed to the financial problems of the patients in a developing country. The overall deaths in our series were four (26.5%) which is slightly higher than other studies which may be due to the fact that this study was conducted during the COVID era with lesser rates of folate supplementation, reduced access to prenatal diagnosis coupled with poor follow-up and compliance of patients post-surgical repair.

CONCLUSION

This study emphasizes the importance of periconceptional folic acid supplementation, prenatal diagnosis, early surgery and meticulous follow-up as being pivotal to improving outcomes in children with NTDs.

Retrospective Examination of Infants With Congenital Neural Tube Defect

INTRODUCTION

In the present study, neonates presenting with neural tube defects (NTDs) and undergoing observation within the confines of the neonatal intensive care unit (NICU) were subjected to a comprehensive assessment encompassing concurrent morbidities, clinical manifestations, laboratory parameters, and instituted interventions.

MATERIALS AND METHODS

A retrospective examination was conducted on the medical records of 135 neonates diagnosed with congenital NTD within the temporal span from 2008 to 2018. The study cohort was drawn from the NICU of the Health Sciences University Erzurum Regional and Research Hospital Health Practice and Research Center.

DISCUSSION

The current investigation encompasses a retrospective analysis of 135 patients diagnosed with NTD who received treatment at the NICU between the years 2008 and 2018. Among these, 74 individuals (54.2%) were male, while 61 (45.8%) were female. Maternal ages ranged from 17 to 46 years, with variations in the number of pregnancies, ranging from 1 to 10. Notably, 71 cases (52.6%) were delivered through normal spontaneous delivery, whereas 64 cases (47.4%) underwent cesarean section. The familial context revealed that five patients (3.6%) had siblings with a history of NTD, while no instances were noted where mothers had received antenatal folic acid support. Birth weights of the neonates ranged from 1425 to 4500 grams. Consanguinity was identified in the parental relationships of 17 cases (12.6%). The average diameter of the neural tube sac was determined to be 4.83 ± 1.94 cm (1-12 cm). Predominantly, the lumbosacral region emerged as the most common site of NTD, with meningomyelocele being the prevailing NTD type. Hydrocephalus coexisted in 67 cases, and notably, 44 instances exhibited the development of hydrocephalus post-sac operation. Eight patients were deemed inoperable, and the initial surgery transpired at an average age of 4.3 ± 2.6 (0-17) days. Flap closure constituted 32 of the surgical interventions, while primary closure was implemented in 95 cases. Neurogenic bladder antedated the operation in 14 patients, and 12 individuals developed neurogenic bladder postoperatively. Ventriculoperitoneal shunt placement was warranted in 47 patients. The average duration of hospitalization was 22.5 ± 14.4 days. Regrettably, three patients died due to complications and infections during their hospital stay.

RESULT

NTD represents a significant cohort of pathologies necessitating a comprehensive and interdisciplinary management strategy. These anomalies are characterized by elevated morbidity and mortality rates, not only exerting substantial financial strains on societal, familial, and state healthcare resources but also inflicting profound emotional distress upon affected families. Crucially, periconceptional strategies emphasizing balanced nutrition coupled with targeted multivitamin and mineral supplementation, particularly the inclusion of folic acid, assume paramount importance in the prophylaxis of this debilitating condition.

Neural Tube Defects from Antenatal Diagnosis to Discharge - a Tertiary Academic Centre Experience

Background

Bleeding Worldwide, approximately 300,000 infants are born annually with neural tube defects (NTDs), which carry a high risk of morbidity and mortality.

Objective

The aim of the study was to describe the experience with NTD patients born at a tertiary academic center.

Methods

A retrospective record review of all neonates with NTD admitted to the neonatal intensive care unit over six years.

Results

Out of the 39 patients identified, 32 (82.1%) were diagnosed antenatally. Most NTD cases were of the myelomeningocele 26 (66.7%) type. The most common site of the myelomeningocele was lumbar, and the thoracolumbar site had the worst prognosis.

Conclusion

Early detection of the disease allows better planning of delivery and treatment decisions. Nevertheless, understanding the magnitude of the problem necessitates adopting public health prevention strategies for better outcomes.

Postnatal Surgical Correction of Myelomeningoceles: Preoperative and Intraoperative Risk Factors Associated with Postoperative Neurologic Outcomes

OBJECTIVE

Open spina bifida or myelomeningocele (MMC) is a congenital defect that results from failure of caudal neurulation. We present a case series of patients who were treated with postnatal surgical correction for MMC, evaluating the possible preoperative and intraoperative risk factors associated with neurologic outcomes.

METHODS

A retrospective chart review of patients who underwent postnatal surgical correction for MMCs over 11 years at our institution was performed. MMCs were classified based on their morphologic configuration into 3 types. Type I includes defects without a sac and there is cerebrospinal fluid (CSF) leak. Type II includes where there is a sac ≤4 cm, with or without CSF leak. Type III includes defects with a sac that are greater than 4 cm.

RESULTS

Fifty patients were included. The median age of gestation at surgery was 37.4 weeks. There were 30 females (60%). All mothers received adequate folate supplementation. All patients underwent surgical correction in the first 48 hours. Lower extremity motor function at the last clinical follow-up was normal in 34 patients (68%). CSF leak, infection, and mortality were 8%, 2%, and 0%, respectively. Twenty-one patients (42%) underwent ventriculoperitoneal shunt for hydrocephalus.

CONCLUSIONS

Despite there being no statistically significant associations with a timely closure, all cases were treated within the first 48 hours and this could influence the low complication rate. Individuals of Hispanic background who received appropriate folate supplementation still had high rates of MMC and we posit that this may be caused in part by a genetic/molecular predisposition.

Postnatal surgery for myelomeningocele in neonates: neurodevelopmental outcomes

BACKGROUND

The study aims to evaluate the neurodevelopmental outcomes of neonates with myelomeningocele (MMC) operated in the postnatal period.

METHODS

This is a prospective follow-up study in a tertiary neonatal intensive care unit. Neurodevelopmental outcomes of term neonates operated for MMC and healthy term newborns were compared with the Bayley Scales of Infant and Toddler Development -Third Edition (BSID III) at 12-18 months.

RESULTS

A total of 57 cases were included in the study (patient group = 27; control group = 30). Demographic data between the groups were similar. Cognitive, linguistic, and motor composite scores of the patient group were lower than those of the control group (p < 0.001). In the patient group, those who underwent ventriculoperitoneal shunt had lower cognitive, language and motor scores than those without shunt (p < 0.05). The cognitive, linguistic, and motor composite scores in the patient group who underwent surgery before 72 h were better than those who underwent surgery after 72 h.

DISCUSSION

In our study, it was found that the neurodevelopmental prognosis of MMC cases requiring ventriculoperitoneal shunt in the postnatal period was significantly worse than those without shunt. It is the first study in which the neurodevelopment of patients with MMC who were operated in the postnatal period was evaluated with BSID III evaluated and delays in all areas were shown in cases with MMC compared to normal cases. Better neurodevelopmental outcomes in patients operated in the first 72 h suggest that early surgery will improve neurodevelopmental outcomes in patients with MMC.

The Quality of Life of Children with Myelomeningocele: A Cross-Sectional Preliminary Study

Objectives: To investigate the relationship between the defects and symptoms caused by myelomeningocele (MMC) and quality of life. Design: A cross-sectional questionnaire survey. Methods: The subjects were 52 parents of children with MMC. Structured questionnaires were used: the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL^TM 4.0) and a Study-Specific Questionnaire (SSQ). Results: The overall PedsQL^TM 4.0 score was 56.4 (SD ± 14.7). A strong, significant negative correlation was found between the children’s age and emotional functioning. Functioning in this area deteriorated with age by a mean of 1.5 points per year of age. Children with no hydrocephalus functioned significantly better than those with this defect in the physical, social, and school areas (p < 0.05). Foot deformities significantly (p = 0.033) adversely affected the children’s physical functioning. Living in a single-parent family had no statistically significant impact on functioning in any of the areas analyzed (p > 0.05). Conclusion: Understanding the QoL of children with MMC and identifying its determinants may help in planning interventions to minimize the adverse impact of the illness.

Duration of In-hospital Stay for Elective Neurosurgical Procedures in a Tertiary Care Hospital

Objective: Public hospitals have fixed days with allotted time slots during which to perform neurosurgical elective cases. If emergency operations or other events preempt these scheduled time slots, the patient remains hospitalized, waiting in queue for a new time slot. We conducted this study to determine the number of days patients remained admitted waiting for elective cases in a tertiary care public hospital, which operates on fixed days.

Materials and methods: This cross-sectional study was conducted in the Department of Neurosurgery Unit B, Medical Teaching Institution (MTI) - Lady Reading Hospital (LRH), Peshawar. We reviewed the admission charts and discharge slips of all patients who were admitted and underwent operations between September 2018 and August 2019. A form was made and was completed with each patients' records like age, gender, number of days spent preoperatively and postoperatively and the total duration of stay, indication for surgery (spinal, cranial, peripheral nerve), etc. Patients who had undergone elective neurosurgical procedures were included while those who had undergone emergency surgeries or had expired during the hospital stay, had been discharged or referred to other centers were excluded from the study. All the data were entered into the statistical software SPSS version 22 (IBM Corp., Armonk, NY) and were converted into tables and charts.

Results: A total of 1818 patients were admitted/discharged during the study period, and of them, 823 patients were admitted for elective neurosurgical procedures. There were 601 (73.7%) males and 222 (26.3%) females with a male to female ratio of approximately 3:1. The age range was from 09 days to 72 years and was further subdivided into six groups. The procedures were broadly divided into cranial, spinal, related to hydrocephalus (HCP)-related, and miscellaneous. Cranial procedures comprised of surgeries for brain tumors, transsphenoidal operations, vascular procedures for aneurysms, and nerve decompressions, and they comprised about 29.43% (n=244) while spinal procedures accounted for 317 (36.63%) procedures, the rest were related to HCP and miscellaneous. Preoperative and postoperative stay durations were calculated and then added to determine the total stay durations and were further stratified for the specific procedures and categorized into days and weeks. About 58.26% (n=143) of cranial cases, and 156 (49.36%) of spinal cases, 37.57% (n=65) of HCP-related cases, and 36.66% (n=41) of cases in the miscellaneous group had a duration of stay between eight days to more than three weeks.

Clinico-epidemiological profile and outcomes of babies with neural tube defects in a tertiary care center in Northern India

INTRODUCTION

Neural tube defects constitute a major source of disability among children. Proper management requires accurate diagnosis, an assessment of the severity of the lesion, a decision whether intervention is warranted, the nature of the intervention, and educating the family of the need for lifelong medical care. But to do so, reliable data regarding presentation and outcome is very crucial.

AIM OF THE STUDY

To discuss the clinical epidemiological profile and outcome of babies admitted with neural tube defects (NTDs).

MATERIAL AND METHODS

Retrospective observational study was done by extracting data from case notes and follow-up files in Department of Neonatology, PGIMER and Dr. RML Hospital, New Delhi over a period from March 2015 to July 2020.

RESULTS

A total of 25 babies were included in the study. Majority of babies were born to mother at a median age group of 24 (19-36) yrs and nearly one-third of them were illiterate. The history of maternal periconceptional folic acid intake was seen in only five babies (21%). Two third of babies were male (64%) and the median age at admission was at 9 (1-27) days of life. Majority of the cases were open types of NTDs with most common type being meningomyelocele (88%) followed by occipital encephalocele (12%) and there was one case of closed type of neural tube defect having lipomeningomyelocele (4%). The most common associated anomaly was hydrocephalus (76%) followed by Arnold chiari malformation (56%). Motor weakness in form of paraparesis or paraplegia was present in 21 (84%) babies and sensory deficit was present in 44% babies. Bowel and bladder dysfuntion was present in 48% of cases. Ventriculitis was the most common associated morbidity (38%). Meningomyelocele (MMC) repair was the most commonly performed primary surgery (33%) followed by Ventriculo-peritoneal (VP) shunt repair (24%). Twelve babies (48%) were discharged while 2 (8%) expired and 11 (44%) babies left against medical advice.

CONCLUSION

Neural tube defect is a congenital disorder with significant morbidity. The clinical severity of the NTDs and the uncertainty in their cause makes this a priority for further research. National policies for prevention, in utero diagnosis, and early surgical intervention are required for a better prognosis.

Risk factors, presentation and outcome of meningomyelocele repair

Objective:

To determine the risk factors, presentation and outcome of meningomyelocele repair

Methods:

We reviewed 150 cases operated for meningomyelocele (MMC) at Jinnah Postgraduate Medical Centre Karachi between May 2015 and May 2018. Data of infants operated for MMC repair was extracted including socioeconomic status, maternal folate intake during pregnancy, head circumference, location and width of the defect, accompanying bladder and limb anomalies and treatments administered. Patients were followed up for a mean period of six months.

Results:

A total of 150 children were evaluated, out of which there were 83(55.3%) males and 67(44.7%) females. All belonged to low socio economic group and prenatal maternal folate intake as risk factor was positive in 103(68.7%) cases. Mean head circumference was 37.4 cm (range, 30.7 to 50 cm). Based on their location, 83(55%) of the defects were lumbosacral, 38(25.4%) were lumbar, 16(10.7%) were thoraco lumbar, 10(6.7%) were thoracic and three (2%) were cervical. Mean size of the meningomyelocele sac was 4.3 cm×5.6 cm (range, 1cm×2 cm to 11cm×8.4cm) and 21(14%) of the babies had a skin defect requiring flap. According to accompanying anomalies, 98(65.3%) of the babies had hydrocephalus, 13(9%) had club foot, four (2.7%) had diastematomyelia and three (2%) had tethered cord. Eighty seven (58%) patients had neurological deficit pre operatively and eight (5.4%) patients with normal power deteriorated after surgery out of which five (3.3%) developed paraplegia and three (2%) developed paraparesis. CSF leak was the major complication encountered in 16(11%) followed by meningitis in seven (5%), while the overall mortality was four (2.6%).

Conclusion:

The practice of periconceptional folic acid supplementation is essential to reduce the prevalence of neural tube defects (NTDs) in the developing world. Improved maternal nutrition with access to quality antenatal care is vital to decrease the prevalence and health burden.

Geographic Analysis of Neurosurgery Workforce in Korea

Objective

In respect of the health and safety of the public, universal access to health care is an issue of the greatest importance. The geographic distribution of doctors is one of the important factors contributing to access to health care. The aim of this study is to assess the imbalances in the geographic distribution of neurosurgeons across Korea.

Methods

Population data was obtained from the National Statistical Office. We classified geographic groups into 7 metropolitan cities, 78 non-metropolitan cities, and 77 rural areas. The number of doctors and neurosurgeons per 100000 populations in each county unit was calculated using the total number of doctors and neurosurgeons at the country level from 2009 to 2015. The density levels of neurosurgeon and doctor were calculated and depicted in maps.

Results

Between 2009 and 2015, the number of neurosurgeons increased from 2002 to 2557, and the ratio of neurosurgeons per 100000 populations increased from 4.02 to 4.96. The number of neurosurgeons per 100000 populations was highest in metropolitan cities and lowest in rural areas from 2009 to 2015. A comparison of the geographic distribution of neurosurgeons in 2009 and 2015 showed an increase in the regional gap. The neurosurgeon density was affected by country unit characteristics (p=0.000).

Conclusion

Distribution of neurosurgeons throughout Korea is uneven. Neurosurgeons are being increasingly concentrated in a limited number of metropolitan cities. This phenomenon will need to be accounted when planning for a supply of neurosurgeons, allocation of resources and manpower, and the provision of regional neurosurgical services.

Infection rate correlated with time to repair of open neural tube defects (myelomeningoceles): an institutional and national study

BACKGROUND

The optimal time to closure of a newborn with an open neural tube defect (NTD-myelomeningocele) has been the subject of a number of investigations. One aspect of timing that has received attention is its relationship to repair site and central nervous system (CNS) infection that can lead to irreversible deficits and prolonged hospital stays. No studies have evaluated infection as a function of surgical timing at a national level. We hypothesized an increase in wound infection in those patients with delays in myelomeningocele repair when evaluated in both a single-center and national database.

METHODS

Treatment outcomes following documented times to transfer and closure were evaluated at Children's Hospital of Los Angeles (CHLA) for the years 2004 to 2014. Data of newborns with a myelomeningocele with varying time to repair were also obtained from non-overlapping abstracts of the 2000-2010 Kids' Inpatient Database (KID) and Nationwide Inpatient Sample (NIS). Poisson multivariable regression analyses were used to assess the effect of time to repair on infection and time to discharge.

RESULTS

At CHLA, 95 neonates who underwent myelomeningocele repair were identified, with a median time from birth to treatment of 1 day. Six (6 %) patients were noted to have postrepair complications. CHLA data was not sufficiently powered to detect a difference in infection following delay in closure. In the NIS, we identified 3775 neonates with repaired myelomeningocele of whom infection was reported in 681 (18 %) patients. There was no significant difference in rates of infection between same-day and 1-day wait times (p = 0.22). Wait times of two (RR = 1.65 [1.23, 2.22], p < 0.01) or more days (RR = 1.88 [1.39, 2.54], p < 0.01), respectively, experienced a 65 % and 88 increase in rates of infection compared to same-day procedures. Prolonged wait time was 32 % less likely at facilities with increased myelomeningocele repair volume (RR = 0.68 [0.56 0.83], p < 0.01). The presence of infection was associated with a 54 % (RR = 1.54 [1.36, 1.74], p < 0.01) increase in the length of stay when compared to neonates without infection.

CONCLUSION

Myelomeningocele closure, when delayed more than 1 day after birth, is associated with an increased rate of infection and length of stay in the national cohort. High-volume centers are associated with fewer delays to repair. Though constrained by limitations of a national coded database, these results suggest that early myelomeningocele repair decreases the rate of infection.
