Perinatal brachial plexus palsy

Brachial Plexus Birth Injury: A Single-Center Study

Infants can sustain traction injury to brachial plexus nerves during birth, called brachial plexus birth injury (BPBI). While spontaneous recovery is possible, upper extremity weakness can linger. We report our experience at a brachial plexus clinic from a retrospective chart review of infants with BPBI from September 2017 to September 2019. We determined Narakas Classification (NC) and Active Movement Scale (AMS) at predetermined follow-up points. Of 15 patients, 8 presented with NC-I, 5 with NC-II, and 2 with NC-III without Horner's syndrome. By 7 months, 3 had spontaneous recovery, and 4 achieved all and another 4 achieved most AMS5-7 scores. Eleven patients undergoing surgery had little-to-no improvement of shoulder abduction and shoulder external rotation AMS categories by 6 months. Our small sample size prevents us from making definitive conclusions but gave beneficial insight into our clinic barriers to follow-up, data collection, and collaboration with physical and occupational therapy.

In vivo biomechanical responses of neonatal brachial plexus when subjected to stretch

Neonatal brachial plexus palsy (NBPP) results from over-stretching of the neonatal brachial plexus during complicated birthing scenarios. The lack of information on the biomechanical response of the neonatal brachial plexus complex when subjected to stretch limits our understanding of the NBPP injury mechanism. This study aims to fill that critical gap by using a neonatal piglet animal model and providing the in vivo biomechanical properties of the neonatal brachial plexus complex when subjected to stretch. Forty-seven brachial plexus levels (identified by the four brachial plexus terminal nerve branches namely musculocutaneous, median, ulnar, and radial), obtained from 16 neonatal Yorkshire piglets (3-5 days old), were subjected to stretch-induced failure. The average maximum load and corresponding strain were reported to be 16.6 ± 1.3 N and 36.1 ± 1.6%, respectively. Maximum loads reported at the musculocutaneous level were significantly lower than the median and radial levels. No differences in strains at failure were reported at all four tested levels. Proximal or distal failure locations were reported in 83% of the tests with 17% mid-length ruptures that were primarily reported at the bifurcation of the median and ulnar brachial plexus levels. Histological studies reported an overall loss of wavy pattern of the nerve fibers, an increase in nerve spacing, fiber disruptions, and blood vessel ruptures in the stretched tissue. This in vivo piglet animal study offers insight into the NBPP mechanism by reporting biomechanical, injury location, and structural damage responses in neonatal brachial plexus when subjected to stretch.

Personalized Use of an Adjustable Movement-Controlled Video Game in Obstetric Brachial Plexus Palsy during Physiotherapy Sessions at School: A Case Report

This case study explores the use of a personalized, adjustable Kinect exergame in 10 physiotherapy sessions for a 10-year-old girl with incomplete right-sided obstetric brachial plexus palsy (OBPP). The aim was to observe the impact on the patient's upper limb mobility that could be achieved through maximization of the player's motivation, possibly due to continuous game parameter adjustments. It had been achieved that the patient was playing 87% of the total gaming time with a personally challenging setting that increased her arm speed from one to four movements. Strength in abduction and flexion were increased by 8 N and 7 N, respectively. Furthermore, the patient showed better muscular balance and an increase of 50% in speed of the Jebsen-Taylor hand function test (JTHFT). The patient reported high levels of motivation, low perception of fatigue, and just slight discomfort. The study found that the use of personalized video games as a complement to conventional physiotherapy can be successful in OBPP patients when the game allows for the adjustment of the difficulty level as a response to personal performance. Predefined difficulty levels and automatic performance analysis can be helpful. Results are promising; however, further research is needed to confirm the results.

A systematic review of brachial plexus injuries after caesarean birth: challenging delivery?

BACKGROUND

Caesarean section (CS) is widely perceived as protective against obstetric brachial plexus injury (BPI), but few studies acknowledge the factors associated with such injury. The objectives of this study were therefore to aggregate cases of BPI after CS, and to illuminate risk factors for BPI.

METHODS

Pubmed Central, EMBASE and MEDLINE databases were searched using free text: ("brachial plexus injury" or "brachial plexus injuries" or "brachial plexus palsy" or "brachial plexus palsies" or "Erb's palsy" or "Erb's palsies" or "brachial plexus birth injury" or "brachial plexus birth palsy") and ("caesarean" or "cesarean" or "Zavanelli" or "cesarian" or "caesarian" or "shoulder dystocia"). Studies with clinical details of BPI after CS were included. Studies were assessed using the National Institutes for Healthy Study Quality Assessment Tool for Case Series, Cohort and Case-Control Studies.

MAIN RESULTS

39 studies were eligible. 299 infants sustained BPI after CS. 53% of cases with BPI after CS had risk factors for likely challenging handling/manipulation of the fetus prior to delivery, in the presence of considerable maternal or fetal concerns, and/or in the presence of poor access due to obesity or adhesions.

CONCLUSIONS

In the presence of factors that would predispose to a challenging delivery, it is difficult to justify that BPI could occur due to in-utero, antepartum events alone. Surgeons should exercise care when operating on women with these risk factors.

Neonatal Iatrogenic Calcinosis Cutis and Heterotopic Calcification Causing Peripheral Brachial Palsy: Case Report and Review of Literature

CASE

Iatrogenic heterotopic calcification and calcinosis cutis secondary to extravasations of intravenous calcium is very rare. We report a case of a neonate treated with intravenous calcium resulting in extravasations causing heterotrophic calcification and calcinosis cutis with subcutaneous mass causing perinatal peripheral brachial palsy.

CONCLUSION

We highlight these rare potential complications of calcium extravasations and recommend conservative treatment and the avoidance of the temptation of surgical excision of any bony lumps as they resolve spontaneously in time. These complications should not be confused as a fracture with callus formation and periosteal reaction.

Differences in the surgical treatment of adult and pediatric brachial plexus injuries among peripheral nerve surgeons

OBJECTIVES

Peripheral nerve surgeons disagree on the optimal timing and treatment of brachial plexus injuries (BPI). This study aims to survey peripheral nerve surgeons on their management of BPI, including disagreement.

METHODS

Surgeons responded to a case-based survey involving traumatic and birth injuries leading to BPI involving the upper and lower trunks, and pre- and post-ganglionic injuries.

RESULTS

Out of 255 invited surgeons, 154 participated, with specialties of Neurosurgery (33.7%), Plastic surgery (32.5%), and Orthopedics (32.5%). For the adult C5-6 avulsion injury, 97.4% agreed they would operate. There was 46.2% disagreement regarding the pediatric upper trunk neuroma-in-continuity case, and similar disagreement (50.0%) was recorded on exploring the brachial plexus for a pediatric lower trunk injury case. High percentages of surgeons were more likely to explore the plexus, such as at upper BPI. Also, most participants reported nerve transfer for the upper and lower trunk avulsion injuries, but there was 55.6% disagreement regarding nerve transfer for the infant with the upper trunk neuroma-in-continuity. Among those elected to perform nerve transfer, most (70.0%-84.5%) would perform an accessory-to-suprascapular nerve transfer for upper BPI, while brachialis-to-anterior interosseous and supinator branch of the radial nerve-to-posterior interosseous were preferred for lower BPI (30.0%-55.9%).

CONCLUSIONS

Substantial disagreement exists among peripheral nerve surgeons in managing adult and pediatric BPI. In adult BPI, most prefer to operate at the time of the presentation and perform extensive nerve transfers. The accessory-suprascapular transfer was recommended for upper BPI, while brachialis and radial nerves were preferred for lower BPI. The most significant disagreements exist in operation and nerve transfer for pediatric upper BPI and brachial plexus explorations. Geography, specialty, and operative volume contribute to the differences seen.

Descriptive Study of Obstetric Brachial Plexus Palsy (OBPP) at a Tertiary Care Hospital

Objective

To study the incidence and risk factors for obstetric brachial plexus palsy and assess the functional outcome.

Material and Methods

Five-year data of infants with OBPP were reviewed. Case-control study was performed using matched controls to identify the risk factors. Infants with OBPP were followed up to assess functional outcome.

Results

Of the 14,184 live births over a period of 5 years from 2013 to 2017, 23 (11 males, 12 females) had OBPP. Incidence of OBPP was 1.6 per 1000 live births. Higher birth weight (p-value 0.002) and instrumental delivery (p-value 0.02) were independent risk factors for obstetric brachial plexus palsy by multivariate logistic regression analysis. No cases of obstetric brachial plexus palsy were seen in babies born by cesarean section. 95% of the infants with obstetric brachial plexus palsy had complete recovery by 4 months of age.

Conclusion

Higher birth weight and instrumental vaginal delivery are independent risk factors for obstetric brachial plexus palsy. Cesarean section may have a protective effect against OBPP. Most infants with obstetric brachial plexus palsy have complete recovery.

Diagnostic accuracy of magnetic resonance imaging for nerve injury in obstetric brachial plexus injury: protocol for systematic review and meta-analysis

BACKGROUND

Early and accurate clinical diagnosis of the extent of obstetric brachial plexus injury (OBPI) is challenging. The current gold standard for delineating the nerve injury is surgical exploration, and synchronous reconstruction is performed if indicated. Magnetic resonance imaging (MRI) is a non-invasive method of assessing the anatomy and severity of nerve injury in OBPI but the diagnostic accuracy is unclear. The primary objective of this review is to determine the diagnostic accuracy of MRI in comparison to surgical brachial plexus exploration for detecting root avulsion in children under 5 with OBPI. The secondary objectives are to determine its' diagnostic accuracy for detecting nerve abnormality and detecting pseudomeningocele(s) in this group.

METHODS

This review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).We will include studies reporting the accuracy of MRI (index test) compared to surgical exploration (reference standard) in detecting any of the three target conditions (root avulsion, any nerve abnormality and pseudomeningocele) in children under five with OBPI. Case reports and studies where the number of true positives, false positives, true negatives and false negatives cannot be derived will be excluded. We plan to search PubMed, Embase and CENTRAL for relevant studies from database inception to 15 June 2022. We will also search grey literature (medRxiv, bioRxiv and Google Scholar) and perform forward and backward citation chasing. Screening and full-text assessment of eligibility will be conducted by two independent reviewers, who will then both extract the relevant data. The QUADAS-2 tool will be used to assess methodological quality and risk of bias of included studies by two reviewers independently. The following test characteristics for the target conditions will be extracted: true positives, false positives, true negatives and false negatives. Estimates of sensitivity and specificity with 95% confidence intervals will be shown in forest plots for each study. If appropriate, summary sensitivities and specificities for target conditions will be obtained via meta-analyses using a bivariate model.

DISCUSSION

This study will aim to clarify the diagnostic accuracy of MRI for detecting nerve injury in OBPI and define its clinical role.

Radiographic imaging modalities for perinatal brachial plexus palsy: a systematic review

PURPOSE

Perinatal brachial plexus palsy (PBPP) has a wide spectrum of clinical symptoms that can range from incomplete paresis of the affected extremity to flaccid arm paralysis. Although there is a high rate of spontaneous recovery within the first two years of life, it remains challenging to determine which patients will benefit most from surgical intervention. The diagnostic and predictive use of various imaging modalities has been described in the literature, but there is little consensus on approach or algorithm. The anatomic, pathophysiological, and neurodevelopmental characteristics of the neonatal and infant patient population affected by PBPP necessitate thoughtful consideration prior to selecting an imaging modality.

METHODS

A systematic review was conducted using six databases. Two reviewers independently screened articles published through October 2021.

RESULTS

Literature search produced 10,329 publications, and 22 articles were included in the final analysis. These studies included 479 patients. Mean age at time of imaging ranged from 2.1 to 12.8 months and investigated imaging modalities included MRI (18 studies), ultrasound (4 studies), CT myelography (4 studies), and X-ray myelography (1 study). Imaging outcomes were compared against surgical findings (16 studies) or clinical examination (6 studies), and 87.5% of patients underwent surgery.

CONCLUSION

This systematic review addresses the relative strengths and challenges of common radiologic imaging options. MRI is the most sensitive and specific for identifying preganglionic nerve injuries such as pseudomeningoceles and rootlet avulsion, the latter of which has the poorest prognosis in this patient population and often dictates the need for surgical intervention.

"How Well" and "How Often" questions for birth brachial plexus injury: a validity and reliability of the pediatric upper extremity motor activity log-revised

PURPOSE

The pediatric upper extremity motor activity log-revised (PMAL-R) is a structured interview that measures use of the affected arm in daily life in children with unilateral pathologies like hemiparetic cerebral palsy (CP) or birth brachial plexus injury (BBPI). This study investigated validity and test-retest reliability of the PMAL-R in children with BBPI.

MATERIALS AND METHODS

The PMAL-R was administered to parents of 132 children with BBPI between 5 and 9 years for validity, also 98 parents were re-interviewed after 3 weeks to establish test-retest reliability. Its concurrent validity was examined by correlating scores on the PMAL-R How Well (HW) and How Often (HO) scales with Brachial Plexus Outcome Measure (BPOM) and Pediatric Outcomes Data Collection Instrument (PODCI) scores.

RESULTS

PMAL-R scores were strongly correlated with BPOM scores (HW, r = 0.943, p < 0.001; HO, r = 0.897, p < 0.001), also strongly correlated with PODCI (HW, r = 0.799, p < 0.001; HO, r = 0.797, p < 0.001). PMAL-R test-retest reliability (intraclass correlation; HO = 0.997, HW = 0.998) and internal consistency (Cronbach's a; HO = 0.99, HW = 0.99) were high.

CONCLUSIONS

The PMAL-R has good reliability and validity for measuring everyday use of the affected arm with "how often" and "how well" questions in children with BBPI. Implications for rehabilitationThe pediatric upper extremity motor activity log-revised (PMAL-R) is the first tool to assess both "how often" and "how well" the affected arm is used in unimanual activities in children with BBPI.PMAL-R is a real-world measure providing valuable information about "how often" and "how well" the affected arm is used to guide treatment.PMAL-R is valid in both concurrent and discriminative validity in children with BBPI.PMAL-R is reliable in children with BBPI.

Neuromuscular electrical stimulation for motor recovery in pediatric neurological conditions: a scoping review

AIM

To explore the breadth of pediatric neurological conditions for which neuromuscular electrical stimulation (NMES) has been studied.

METHOD

Databases (PubMed, Google Scholar, Scopus, and Embase) were searched from 2000 to 2020, using the search terms 'neuromuscular electrical stimulation' OR 'functional electrical stimulation' with at least one of the words 'pediatric OR child OR children OR adolescent', and without the words 'dysphagia OR implanted OR enuresis OR constipation'. Articles focused on adults or individuals with cerebral palsy (CP) were excluded.

RESULTS

Thirty-five studies met the inclusion criteria, with a total of 353 pediatric participants (293 unique participants; mean age 7y 4mo, range 1wk-38y). NMES was applied in a range of pediatric conditions other than CP, including stroke, spinal cord injury, myelomeningocele, scoliosis, congenital clubfoot, obstetric brachial plexus injury, genetic neuromuscular diseases, and other neuromuscular conditions causing weakness.

INTERPRETATION

All 35 studies concluded that NMES was well-tolerated and most studies suggested that NMES could augment traditional therapy methods to improve strength. Outcome measurements were heterogeneous. Further research on NMES with larger, randomized studies will help clarify its potential to improve physiology and mobility in pediatric patients with neuromuscular conditions. What this paper adds Neuromuscular electrical stimulation (NMES) appears to be tolerated by pediatric patients. NMES shows potential for augmenting recovery in pediatric patients with a range of rehabilitation needs.

A Systematic Review of the Tensile Biomechanical Properties of the Neonatal Brachial Plexus

Brachial plexus (BP) birth injury has a reported incidence of 1 to 4 per 1000 live births. During complicated deliveries, neonatal, maternal, and other birth-related factors can cause over-stretching or avulsion of the neonatal brachial plexus leading to injury. Understanding biomechanical responses of the neonate brachial plexus when subjected to stretch can offer insight into the injury outcomes while guiding the development of preventative maneuvers that can help reduce the occurrence of neonatal brachial plexus injuries. This review article aims to offer a comprehensive overview of existing literature reporting biomechanical responses of the brachial plexus, in both adults and neonates, when subjected to stretch. Despite the discrepancies in the reported biomechanical properties of the brachial plexus, available studies confirm the loading rate and loading direction dependency of the brachial plexus tissue. Future studies, possibly in vivo, that utilize clinically relevant neonatal large animal models can provide translational failure values of the biomechanical parameters for the neonatal brachial plexus when subjected to stretch.

Requirements for tele-health in children with obstetric brachial plexus palsy during Covid-19-like situations

The purpose of the study was to investigate families’ concerns and service requirements during the Covid-19 lockdown. In case of tele-consultation, we also aimed to assess the effects of this service on coping and the family’s worries. At end of lockdown, we contacted the parents of 67 obstetric brachial plexus palsy patients (0–10 years age) by e-mail. During lockdown, 42 of the families had had a tele-consultation with our team, while 25 reported that not receiving any service. A questionnaire consisting of 6 questions was sent to the families, and data were analyzed according to 4 age-groups. Parents' concerns varied according to the children’s age group (p = 0.001). All families replied that their children should receive remote services during Covid-19-like situations (p = 0.173). Parents of the 42 children who had tele-consultations reported that this had alleviated their worries, independently of age-group (p = 0.160). The usefulness of tele-consultation to manage the lockdown situation differed according to age-group (p = 0.002). The parents of under-3-year-olds experienced more worry during lockdown, but all respondents reported needing remote services. Although the tele-consultation alleviated the worries of almost all families, it was most useful in managing lockdown in families with under-3-year-olds.

The outcome of soft-tissue release and tendon transfer in shoulders with brachial plexus birth palsy

Background

Shoulder involvement in brachial plexus birth palsy is common, and the adduction, internal rotation contracture deformity often requires some form of surgical treatment. There are very few long-term reports on release of contracted muscles and tendon transfers, especially in older children. We are reporting the single-center results of such a surgery with detailed outcome analysis.

Methods

The prospectively collected data from brachial plexus birth palsy cases who had undergone contracture release and tendon transfer were retrospectively studied and examined. The new Mallet and functional scores were compared with the original data forms and then analyzed. The radiographic evidence of glenoid dysplasia and its correlation with age and functional outcome was assessed.

Results

A total of 82 cases with surgery at mean age of 9.5 ± 5.09 years and a follow-up of 8 ± 3.8 (3-20) years entered the study. Of these, 56% of cases had 7 to 20 years of age at surgery. Fifty-four (66%) patients had only shoulder surgery, and 28 (34%) required additional reconstructive surgeries for hand and wrist. Moderate to severe glenohumeral dysplasia was present in 38%. The preoperative Mallet score of 10.6 ± 2.97 improved to 19.3 ± 3.39 (P < .001). Eighty-one percent of patients showed improvement in “reaching face” functions, 71% in “above head” functions, and 74% in “midline functions.” The cases with lack of improvement in midline function mostly belonged to pan-plexus injuries. Noticeable subjective and objective improvement was also observed in cases with glenohumeral dysplasia in their Mallet and functional scores (P < .001). The improvement in function and subjective satisfaction of 92% was observed irrespective of age at surgery.

Conclusion

Soft-tissue release and tendon transfer for brachial plexus birth palsy shoulder can improve function and limb appearance even in older children and young adults and even in the presence of glenohumeral dysplasia.

Recommendations for management of neonatal brachial plexus palsy: Based on clinical review

STUDY DESIGN

Descriptive report.

INTRODUCTION

Neonatal brachial plexus palsy (NBPP) involves a partial or total injury of the nerves that originate from spinal roots C5-C8 and T1. The reported incidence of NBPP is between 0.38 and 5.1 in 1000 births.

PURPOSE OF THE STUDY

This study describes the management NBPP in the first 3 years of life and to develop an assessment framework for infants with NBPP and postoperative guidelines for those undergoing primary surgery.

METHODS

Retrospective medical record audit from 2012 to 2017.

RESULTS

Of 187 children referred to brachial plexus clinic (BPC), 138 were new referrals and included in the audit. The average number of new referrals per annum was 37; average age at referral was 6.61 week; average age at first appointment was 16.9 weeks. Of the 138 infants, 104 were initially assessed by a physiotherapist before attending BPC. The most common comorbidity was plagiocephaly.

DISCUSSION

From 2012 to 2017, birth location, birth facility, referral source, and time between referral and initial assessment have remained stable. The age at referral, age at which the child was first assessed, and the number of children who received services externally before attending the hospital all decreased. The number of children seen by a physiotherapist before attending BPC increased. An NBPP assessment framework, including critical time points for assessment, and postoperative guidelines for infants and children undergoing primary surgery were created.

CONCLUSIONS

Early referral is essential for effective management of NBPP and ideally infants should be assessed and management implemented before 3 months of age.

Could Subtle Obstetrical Brachial Plexus Palsy Be Related to Unilateral B Glenoid Osteoarthritis?

Background: Several factors associated with B glenoid are also linked with obstetrical brachial plexus palsy (OBPP). The purpose of this observational study was to determine the incidence of OBPP risk factors in type B patients. Methods: A cohort of 154 patients (68% men, 187 shoulders) aged 63 ± 17 years with type B glenoids completed a questionnaire comprising history of perinatal characteristics related to OBPP. A literature review was performed following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) to estimate the incidence of OBPP risk factors in the general population. Results: Twenty-seven patients (18%) reported one or more perinatal OBPP risk factors, including shoulder dystocia (n = 4, 2.6%), macrosomia >4 kg (n = 5, 3.2%), breech delivery (n = 6, 3.9%), fetal distress (n = 8, 5.2%), maternal diabetes (n = 2, 1.3%), clavicular fracture (n = 2, 1.3%), and forceps delivery (n = 4, 2.6%). The comparison with the recent literature suggested that most perinatal OBPP risk factors were within the normal range, although the incidence of shoulder dystocia, forceps and vaginal breech deliveries exceeded the average rates. Conclusion: Perinatal factors related to OBPP did not occur in a higher frequency in patients with Walch type B OA compared to the general population, although some of them were in the high normal range.

The Effects of Virtual Reality on Upper Extremity in Patients with Obstetric Brachial Plexus Injury

The present study aimed to examine the effects of playing Nintendo Wii games on upper extremity functions compared with conventional physiotherapy, in children with obstetric brachial plexus injury (OBPI). Twenty-two patients with brachial plexus injuries were enrolled. The patients were divided into two groups by simple randomization. The control group (conventional physiotherapy group [CTG]: n = 11) received conventional physiotherapy for 6 weeks (40 minutes per day, for 4 days per week). The study group, called Nintendo Wii group (NWG; n = 11), received conventional physiotherapy as well as tennis, baseball, and boxing games with Nintendo Wii on days when there was no physical therapy. The upper extremity range of motion (ROM) was evaluated using a digital goniometer, motor function was assessed using the Active Movement Scale (AMS), and shoulder functions were assessed with the Mallet Scoring System (MSS). Virtual reality treatment had a positive effect on shoulder flexion, forearm pronation, wrist flexion, ROM, and functionality (p < 0.05). There was a significant improvement in shoulder abduction and shoulder external rotation in the CTG (p < 0.05). There was no significant difference in the MSS values of either groups (p > 0.05). As per the AMS, in the NWG, the shoulder internal rotation increased significantly (p < 0.05). Nintendo Wii treatment used in addition to conventional physiotherapy may be effective in increasing upper extremity functions in children with OBPI.

A Rare Case of Contralateral Diaphragm Paralysis following Birth Injury with Brachial Plexus Palsy: A Case Report and Review of the Literature

Clinical History. A 4.4 kg male was born to a 25-year-old, G2P1, nondiabetic woman at 39 and 5/7 weeks. Delivery was complicated by shoulder dystocia requiring forceps-assisted vaginal delivery, resulting in left arm Erb's palsy secondary to left brachial plexus injury. He was born with low muscle tone and bradycardia and subsequently required intubation for poor respiratory effort. He was extubated on day one of life but continued to be tachypneic and have borderline oxygen saturation, requiring intensive care. Chest radiographs demonstrated a progressive clearing of his lung fields, consistent with presumptively diagnosed meconium aspiration. However, a persistent elevation of the right hemidiaphragm was noted, and his tachypnea and increased work of breathing continued. Focused ultrasound of the diaphragm was performed, confirming decreased motion of the right hemidiaphragm. Following a multidisciplinary discussion, thoracoscopic right diaphragm plication was performed on the 33rd day of life. He was extubated postoperatively and subsequently weaned to room air with a notable decrease in tachypnea over 48 hours. He was discharged on postoperative day 12 and continues to thrive at 6 months of age without respiratory embarrassment. Purpose. Ipsilateral phrenic nerve injury with diaphragm paralysis from shoulder dystocia during vaginal delivery is a recognized phenomenon. Herein, we present a case of contralateral diaphragm paralysis in order to draw attention to the clinician that this discordance is possible. Key Points. According to Raimbault et al., clinical management of newborns who experience birth injury is a multidisciplinary effort. According to Fitting and Grassino, though most cases of phrenic nerve injuries are ipsilateral to shoulder dystocia brachial plexus palsy, contralateral occurrence is possible and should be considered. According to Waters, diaphragm plication is a safe and effective operation.

A Systematic Review of the Electrodiagnostic Assessment of Neonatal Brachial Plexus

Despite improvements in obstetric care, neonatal brachial plexus palsy continues to significantly impact infants’ lives worldwide, with an incidence of 1 to 4 per 1000 live births. While a majority of affected infants recover spontaneously by three months, 20-30% suffer permanent functional deficits that significantly impair their quality of life. Anatomical complexity of the brachial plexus results in varying degrees of injury and pathological changes at multiple levels within the plexus. Current clinical diagnosis relies on electrodiagnostic techniques such as nerve conduction (i.e., motor and sensory) and electromyography studies. These techniques not only aid clinicians to differentiate between axonal and demyelinating lesions, evident by changes in signal shape and conduction, but also provide prognostic information in cases of brachial plexus injuries. The presented study offers a comprehensive review of existing literature on electrodiagnostic techniques employed for assessing neonatal brachial plexus injuries.

Obstetric Brachial Plexus Palsy: Can a Unilateral Birth Onset Peripheral Injury Significantly Affect Brain Development?

Purpose: Examine brain structure and function in OBPP and relate to clinical outcomes to better understand the effects of decreased motor activity on early brain development. Methods: 9 OBPP, 7 controls underwent structural MRI scans. OBPP group completed evaluations of upper-limb function and functional near-infrared spectroscopy (fNIRS) during motor tasks. Results: Mean primary motor area volume was lower in both OBPP hemispheres. No volume differences across sides seen within groups; however, Asymmetry Ratio in supplementary motor area differed between groups. Greater asymmetry in primary somatosensory area correlated with lower ABILHAND-Kids scores. fNIRS revealed more cortical activity in both hemispheres during affected arm reach. Conclusion: Cortical volume differences or asymmetry were found in motor and sensory regions in OBPP that related to clinical outcomes. Widespread cortical activity in fNIRS during affected arm reach suggests reorganization in both hemispheres and is relevant to rehabilitation of those with developmental peripheral and brain injuries.

Integrated Electromyography: Discriminant Analysis and Prediction of Recovery 3 to 6 Years After Brachial Plexus Birth Injury

PURPOSE

To assess the recovery likelihood, 3 to 6 years after brachial plexus birth injury (BPBI), and predict the functional recovery from integrated electromyography (IEMG).

METHODS

Thirty children with BPBI limited to C5-C6 lesion participated. Maximal electromyography activity of deltoid and biceps brachii was measured at entry. Shoulder and elbow functions were assessed at the baseline and at 4 intervals across 2 years.

RESULTS

Shoulder and elbow function significantly changed across the follow-up period. Shoulder and elbow functions were significantly dependent on deltoid and biceps brachii muscles' IEMG level, respectively, with the groups showing higher IEMG achieving better recovery. The deltoid and biceps IEMG explained a portion of the improvement in shoulder and elbow function over 2 years.

CONCLUSION

Recovery of the shoulder and elbow function continues 3 to 6 years after BPBI. IEMG may partially explain variation in the prognosis for children with BPBI.

Pseudo paralysis of the shoulder and increased C-reactive protein are predictive factors for septic shoulder in children superior to other clinical symptoms: a retrospective case series of 25 patients

PURPOSE

The aim of the study was to evaluate predictable parameters with the highest sensitivity used in the diagnosis of children septic shoulder arthritis.

METHODS

All children treated in our paediatric orthopaedic hospital between 2000 and 2017 with intraoperative verified septic arthritis of the shoulder were included in this retrospective study. Diagnostic procedures e.g. ultrasound, MRI, radiograph or blood samples as well as typical clinical symptoms were evaluated as predictable parameters for septic shoulder arthritis in paediatric patients. Descriptive statistics as well as sensitivity analysis were performed.

RESULTS

In all, 25 children, 20 boys and five girls, aged from eight days to 15 years, were included for further statistical analysis. All parameters included were tested for sensitivity with binomial confidence intervals (Cis) of 95%. Predictive parameters with highest sensitivity were pseudo paralysis (100%, CI 0.86 to 1.00) and C-reactive protein (CRP) (96%, CI 0.79 to 0.99) superior to temperature (52%, CI 0.3 to 0.73), white blood count (11%, CI 0.01 to 0.34), radiograph (21%, CI 0.04 to 0.50), ultrasound (71%, CI 0.47 to 0.88) or MRI (100%, CI 0.78 to 1.00).

CONCLUSION

The diagnosis of a septic arthritis of the shoulder in children can be challenging for the clinician and especially for the resident doctor. Clinical symptoms such as pseudo paralysis and increased CRP level must be considered as predictive markers not to delay further diagnostics and treatment.

Prevalence and predisposing factors of brachial plexus birth palsy in a regional hospital in Ghana: a five year retrospective study

Introduction

Brachial plexus birth injury is one of the challenges associated with maternal delivery, with varying prevalence between countries. Brachial plexus birth injury poses negative health implications to children and also has socio-economic implications on families and the community as a whole. To treat brachial plexus birth injury, a multi-disciplinary treatment approach is recommended. Brachial plexus birth palsy (BPBP) is categorised into two-upper plexus injury (Erb's palsy) and lower plexus injury (Klumpke's palsy). These categories present with various degrees of injuries, with less severe injuries responding well to treatment and in most instances may resolve on their own, but serious and complicated injuries will require a multi-disciplinary treatment approach to treat and/or manage. Effective treatment and management depends on adequate knowledge of the disease condition. These include the risk factors and prevalence of brachial plexus birth palsy within a particular population at a specific period in time. The aim of this study was to determine the risk factors and the prevalence of a hospital based brachial plexus birth palsy within a five-year period (2013-2017).

Methods

A five-year retrospective study design was used. The study involved selection of all clients' diagnosed with brachial plexus birth palsy, where their gender, birth weight, complications at birth, type of brachial plexus suffered, mothers' diabetes status, mother's age, birth attendant, side of affectation, presentation at birth and mode of delivery were recorded.

Results

The prevalence rate of brachial plexus birth palsy was 14.7% out of a total of three hundred and twenty (320) cases reviewed over the study period in the Volta Regional Hospital. Erb's palsy was found to be the modal type of BPBP in this population (93.6%).

Conclusion

There is the need to provide a nationwide education on the risk factors that predispose babies to brachial plexus birth palsy. There is also the need for frequent antenatal visit by pregnant women; this will help in the provision of best antenatal history, diagnostic investigation in determining the birth weight and safe mode of delivery.

Obstetric brachial plexus palsy - A prospective, population-based study of incidence, recovery and long-term residual impairment at 10 to 12 years of age

AIM

To assess the long-term outcome and evaluate prognostic factors in obstetric brachial plexus palsy (OBPP).

METHODS

Of all 114 children with OBPP born in western Sweden in 1999-2001, 98 (61 males, 37 females) were invited to participate. A questionnaire on the symptoms of the OBPP was sent out and those with persisting symptoms were examined in terms of muscle strength, range of motion (ROM), activities of daily living (ADL), pain and sensibility at the age of 10-12 years. Contact was made by 87 children.

RESULTS

The incidence of persisting OBPP at 10-12 years of age was calculated as 19 per 38,749 live births or 0.49 per 1000. Symptoms were reduced muscle strength and ROM in the arm. Eight children reported pain, four had impaired sensibility and ten children described some difficulties in ADL. Muscle strength in forearm supination, shoulder external rotation and elbow flexion at three months of age can be used to predict outcome.

INTERPRETATION

Most children with an OBPP recover completely, but one in five has symptoms of the injury at 10-12 years of age. Muscle strength in the arm at three months of age can be used to predict outcome.

Rare case of a newborn baby with left-sided Erb's palsy and a contralateral/right-sided paralysis of the diaphragm

Brachial plexus birth injury (BPBI) and phrenic nerve injury can sometimes occur concurrently in neonates following difficult deliveries like breech presentation, shoulder dystocia, forceps or vacuum extraction. Phrenic nerve palsy should be suspected in a newborn with respiratory distress and an elevated hemidiaphragm on the imaging studies in presence of the associated risk factors. The right side is affected more often than the left side and most of it is associated with BPBI. We present here a rare case of a newborn baby with a left-sided Erb's palsy and a contralateral/right-sided diaphragmatic paralysis who recovered from the persistent respiratory distress and feeding difficulties following plication of the diaphragm. The left-sided Erb's palsy also fully recovered at follow-up examination.

Effect of virtual reality versus conventional physiotherapy on upper extremity function in children with obstetric brachial plexus injury

OBJECTIVES

The objective was to evaluate the effects of virtual reality versus conventional physiotherapy on upper extremity function in children with obstetric brachial plexus injury.

METHODS

Forty children with Erb's palsy were selected for this randomized controlled study. They were assigned randomly to either group A (conventional physiotherapy program) or group B (virtual reality program using Armeo® spring for 45 min three times/week for 12 successive weeks). Mallet system scores for shoulder function and shoulder abduction, and external rotation range of motion (ROM) were obtained; shoulder abductor, and external rotators isometric strength were evaluated pre-and post-treatment using Mallet scoring system, standard universal goniometer, and handheld dynamometer.

RESULTS

The results of this study indicate that the children in both groups showed improvement in shoulder functions post-treatment with greater improvements in group B. The abduction muscle strength after treatment was 8.53 and 11.3 Nm for group A and group B, respectively. The external rotation muscle strength after treatment was 5.88 and 7.45 Nm for group A and group B, respectively.

CONCLUSIONS

The virtual reality program is a significantly more effective than conventional physiotherapy program in improving the upper extremity functions in children with obstetric brachial plexus injury.

Glenoid morphology in obstetrical brachial plexus lesion: a three-dimensional computed tomography study

BACKGROUND

Obstetric brachial plexus lesion (OBPL) frequently leads to glenohumeral dysplasia, and excessive retroversion of the glenoid is among the best known developmental disturbances. Most analyses of the glenoid are based on 2-dimensional (D) imaging and do not address glenoid inclination or provide information on the glenoid in the sagittal plane. We aim to describe the 3-D deformity of the glenoid in children with OBPL.

METHODS

Preoperative computed tomography (CT) scans of the nonaffected and the affected scapula of 24 children (aged 5 to 12 years) with developmental disturbances after OBPL years were analyzed. The dimensions of the scapula and the deformation of the glenoid were visualized in 3-D.

RESULTS

The retroversion of the glenoid fossa was greater in all affected shoulders, and 2-D measurements significantly overestimated retroversion compared with angles measured in 3-D. The inclination of the glenoid fossa was altered, and a distal bony edge loss was observed on 3-D reformations in the sagittal plane. The reliability of the measured angles was excellent, and the κ agreement for the description of the glenoid form was substantial. Furthermore, the dimensions of the scapula were significantly smaller on the affected shoulders.

CONCLUSION

OBPL is indeed a 3-D disorder. Our measurements revealed excessive retroversion of the glenoid fossa, and the reliability of the 3-D CT measurements was superior to their 2-D counterparts. 3-D CT reformations of the glenoid in the coronal and the sagittal plane added further to 3-D understanding of glenoid morphology in OBPL. These new findings legitimatize a 3-D CT-based description of the glenoid deformities connected with OPBL.

Obstetrical brachial plexus injury (OBPI): Canada's national clinical practice guideline

OBJECTIVE

The objective of this study was to establish an evidence-based clinical practice guideline for the primary management of obstetrical brachial plexus injury (OBPI). This clinical practice guideline addresses 4 existing gaps: (1) historic poor use of evidence, (2) timing of referral to multidisciplinary care, (3) Indications and timing of operative nerve repair and (4) distribution of expertise.

SETTING

The guideline is intended for all healthcare providers treating infants and children, and all specialists treating upper extremity injuries.

PARTICIPANTS

The evidence interpretation and recommendation consensus team (Canadian OBPI Working Group) was composed of clinicians representing each of Canada's 10 multidisciplinary centres.

OUTCOME MEASURES

An electronic modified Delphi approach was used for consensus, with agreement criteria defined a priori. Quality indicators for referral to a multidisciplinary centre were established by consensus. An original meta-analysis of primary nerve repair and review of Canadian epidemiology and burden were previously completed.

RESULTS

7 recommendations address clinical gaps and guide identification, referral, treatment and outcome assessment: (1) physically examine for OBPI in newborns with arm asymmetry or risk factors; (2) refer newborns with OBPI to a multidisciplinary centre by 1 month; (3) provide pregnancy/birth history and physical examination findings at birth; (4) multidisciplinary centres should include a therapist and peripheral nerve surgeon experienced with OBPI; (5) physical therapy should be advised by a multidisciplinary team; (6) microsurgical nerve repair is indicated in root avulsion and other OBPI meeting centre operative criteria; (7) the common data set includes the Narakas classification, limb length, Active Movement Scale (AMS) and Brachial Plexus Outcome Measure (BPOM) 2 years after birth/surgery.

CONCLUSIONS

The process established a new network of opinion leaders and researchers for further guideline development and multicentre research. A structured referral form is available for primary care, including referral recommendations.

Cerebral Reorganization in Patients with Brachial Plexus Birth Injury and Residual Shoulder Problems

The functional outcome after a brachial plexus birth injury (BPBI) is based on changes in the peripheral nerve and in the central nervous system. Most patients with a BPBI recover, but residual deficits in shoulder function are not uncommon. The aim of this study was to determine cerebral activation patterns in patients with BPBI and also residual symptoms from the shoulder. In seven patients (six females and one male, aged 17–23 years) with a BPBI and residual shoulder problems (Mallet score IV or lower), the cerebral response to active movement of the shoulder and elbow of the injured and healthy arm was monitored using functional magnetic resonance imaging at 3 T. Movements, i.e., shoulder rotation or elbow flexion and extension, of the injured side resulted in a more pronounced and more extended activation of the contralateral primary sensorimotor cortex compared to the activation seen after moving the healthy shoulder and elbow. In addition, moving the shoulder or elbow on the injured side resulted in increased activation in ipsilateral primary sensorimotor areas an also increased activation in associated sensorimotor areas, in both hemispheres, located further posterior in the parietal lobe, which are known to be important for integration of motor tasks and spatial aspects of motor control. Thus, in this preliminary study based on a small cohort, patients with BPBI and residual shoulder problems show reorganization in sensorimotor areas in both hemispheres of the brain. The increased activation in ipsilateral sensorimotor areas and in areas that deal with both integration of motor tasks and spatial aspects of motor control in both hemispheres indicates altered dynamics between the hemispheres, which may be a cerebral compensation for the injury.

High prevalence of cranial asymmetry exists in infants with neonatal brachial plexus palsy

PURPOSE

This study aimed to: 1) evaluate the prevalence of cranial asymmetry (positional plagiocephaly) in infants with neonatal brachial plexus palsy (NBPP); 2) examine the association of patient demographics, arm function, and NBPP-related factors to positional plagiocephaly; and 3) determine percentage of spontaneous recovery from positional plagiocephaly and its association with arm function.

METHODS

Infants < 1 year of age with NBPP and no previous exposure to plagiocephaly cranial remolding therapy or surgical intervention were recruited for this prospective cross-sectional study. Positional plagiocephaly (diagonal difference) measurements were captured using a fiberglass circumferential mold of the cranium. Included infants were divided into 2 groups: 1) those with positional plagiocephaly at most recent evaluation (plagio group), including infants with resolved positional plagiocephaly (plagio-resolved subgroup); and 2) those who never had positional plagiocephaly (non-plagio group). Standard statistics were applied.

RESULTS

Eighteen of 28 infants (64%) had positional plagiocephaly. Delivery type might be predictive for plagiocephaly. Infants in the non-plagio group exhibited more active range of motion than infants in the plagio group. All other factors had no significant correlations.

CONCLUSIONS

A high prevalence of positional plagiocephaly exists among the NBPP population examined. Parents and physicians should encourage infants to use their upper extremities to change position and reduce chance of cranial asymmetry.

Transient neonatal radial nerve palsy. A case series and review of the literature

Transient neonatal radial nerve palsy manifests at birth by wrist drop and intact elbow and shoulder function. Spontaneous resolution is universal. We present a case series, including two bilateral cases, and a review of the cases found in the English literature, hypothesizing how this condition is probably misdiagnosed as brachial plexus injury.

Obstetrical brachial plexus injury: burden in a publicly funded, universal healthcare system

OBJECT The aim of this study was to determine the volume and timing of referrals for obstetrical brachial plexus injury (OBPI) to multidisciplinary centers in a national demographic sample. Secondarily, we aimed to measure the incidence and risk factors for OBPI in the sample. The burden of OBPI has not been investigated in a publicly funded system, and the timing and volume of referrals to multidisciplinary centers are unknown. The incidence and risk factors for OBPI have not been established in Canada. METHODS This is a retrospective cohort study. The authors used a demographic sample of all infants born in Canada, capturing all children born in a publicly funded, universal healthcare system. OBPI diagnoses and corresponding risk factors from 2004 to 2012 were identified and correlated with referrals to Canada's 10 multidisciplinary OBPI centers. Quality indicators were approved by the Canadian OBPI Working Group's guideline consensus group. The primary outcome was the timing of initial assessment at a multidisciplinary center, "good" if assessed by the time the patient was 1 month of age, "satisfactory" if by 3 months of age, and "poor" if thereafter. Joinpoint regression analysis was used to determine the OBPI incidence over the study period. Odds ratios were calculated to determine the strength of association for risk factors. RESULTS OBPI incidence was 1.24 per 1000 live births, and was consistent from 2004 to 2012. Potential biases underestimate the level of injury identification. The factors associated with a very strong risk for OBPI were humerus fracture, shoulder dystocia, and clavicle fracture. The majority (55%-60%) of OBPI patients identified at birth were not referred. Among those who were referred, the timing of assessment was "good" in 28%, "satisfactory" in 66%, and "poor" in 34%. CONCLUSIONS Shoulder dystocia was the strongest modifiable risk factor for OBPI. Most children with OBPI were not referred to multidisciplinary care. Of those who were referred, 72% were assessed later than the target quality indicator of 1 month that was established by the national guideline consensus group. A referral gap has been identified using quality indicators at clinically relevant time points; this gap should be addressed with the use of knowledge tools (e.g., a clinical practice guideline) to target variations in referral rates and clinical practice. Interventions should guide the referral process.

NOSOLOGY OF HAND DISEASES IN CHILDREN AND ADOLESCENTS OPERATED IN PROVISIONAL FACILITIES IN A MODEL HOSPITAL - PERNAMBUCO STATE, BRAZIL

To report the frequencies of congenital hand diseases in patients who underwent surgery on a collective mobilization basis at SOS Hand, Recife, Pernambuco, between 2005 and 2009. Methods: Information was collected from 833 children and adolescents who were examined in eight missions. Results: Among the patients, 306 (36.7%) underwent surgery: 240 (78.4%) because of congenital malformation and 66 (21.6%) because of acquired lesions. The most frequent congenital malformations were: syndactyly, 72 cases (30.0%); polydactyly, 30 cases (12.5%); bifid thumb, 19 cases (7.9%); complex hand malformation, 14 cases (5.8%); cleft hand, 13 cases (5.4%); trigger finger, 12 cases (5.0%); camptodactyly, 11 cases (4.6%); and brachysyndactyly, 9 cases (3.7%). The most frequently acquired injuries were: obstetric traumatic lesions, 26 cases (39.4%); hand trauma sequelae, 18 cases (27.3%); cerebral paralysis sequelae, 7 cases (10.6%); electric shock sequelae, 5 cases (7.6%); and burn sequelae, 4 cases (6.1%). Conclusion: The nosology of hand diseases is similar to that of large series of elective surgery, especially regarding congenital deformities. The frequency of acquired hand lesions seems to be higher than the frequency in international series. The collective mobilization system for hand surgery is important for decreasing the need for this activity in public institutions, and it has been shown to be very efficient. The success of the project may provide support for the Brazilian National Health System to enroll hand surgeons in the on-call system, in emergency units.

Late neonatal presentation of reduced arm movement due to painful infective lymphadenopathy

We report two cases of 21-day-old male infants, Baloo and Bagheera, both admitted with unilateral reduced arm movement secondary to painful lymphadenopathy, which is a presentation previously unreported in the paediatric literature. The only abnormal finding following investigations in both neonates was infective lymphadenopathy; we hypothesise that the inflamed lymph nodes were tender when the surrounding muscles, fascia or skin were moved, so that the infants learnt to reduce arm movement to minimise pain. This report explores the differential diagnoses for reduced arm movement in neonates, and highlights the importance of sepsis with painful lymphadenopathy as a differential diagnosis in neonates presenting with reduced arm movement.

Bone age in children with obstetrical brachial plexus palsy: effect of peripheral nerve injury on skeletal maturation

The purpose of this retrospective study was to analyze the effect of peripheral nerve injury on the skeletal maturation process. The bone ages of the affected and unaffected hand-wrists of 42 children with obstetrical brachial palsy were determined according to the Greulich and Pyle atlas. In 23 patients, the bone ages of the both sides were identical (bone-age-symmetrical group), in 19 patients the bone age of the affected side was delayed (bone-age-delayed group). The mean bone age of the affected side was delayed 0.48 ± 0.25 years that of the unaffected side (P = .000), and the delay of bone age was inversely correlated with chronological age (R (2) = .45, P < .02) in the bone-age-delayed group. Skeletal retardation can be recognized after appearance of ossification centers by plain radiography, dating from the third month of life, in early infancy. Thus, bone age determination method might be helpful for predicting potential future limb shortness.

[Acute osteomyelitis of the clavicle in the newborn infant: a case report]

Acute osteomyelitis of the clavicle accounts for less than 3% of osteomyelitis cases, with its usual location in the middle third. It may be hematogenous, due to contiguity, or secondary to catheterization of the subclavian vein or neck surgery. The diagnosis is often delayed, and clinical symptoms may simulate obstetric brachial plexus palsy in young children. We report a new case of osteomyelitis of the clavicle in a 30-day-old newborn.

Neonatal brachial plexus palsy with vaginal birth after cesarean delivery: a case-control study

OBJECTIVE

The objective was to determine the rate of neonatal brachial plexus palsy (NBPP) among women with vaginal birth after cesarean delivery (VBAC) and to compare the peripartum characteristics with control subjects.

STUDY DESIGN

The Maternal-Fetal Medicine Unit cesarean registry data were used to identify nonanomalous singleton pregnancies with VBAC and NBPP at gestational age of ≥37 weeks (term) and 4 control subjects (matched for gestational age and diabetes mellitus status but without brachial injury). Odds ratio (OR) and 95% confidence intervals (CIs) were calculated.

RESULTS

Among 11,313 VBACs at term, there were 23 women with NBPP (rate of 2.0/1000 women). Newborn infants with NBPP, compared with control infants, were significantly more likely to weigh ≥4000 g (48% vs 10%, respectively; OR, 8.45; 95% CI, 2.58-28.44) and to require admission to the neonatal intensive care unit (30% vs 13%; OR, 12.98; 95% CI, 2.61-72.18).

CONCLUSION

Women who desire VBAC should be informed about the low rate of NBPP and, if eligible, encouraged to have a trial of labor after cesarean delivery.

Kinesio arm taping as prophylaxis against the development of Erb's Engram

An Erb’s Engram is a common debility that develops in recovering children with Erb’s palsy. The purpose of this study was to investigate the effect of kinesiotaping over the deltoid and the forearm on the development of proper upper extremity function in children recovering from Erb’s palsy. Thirty patients with Erb’s palsy participated for 3 months in this study and were equally divided into two groups; control group A and study group B. The two groups received the same designed physical therapy program, while group B along the program, received kinesiotaping over the deltoid and the forearm. The subjects were evaluated, pre and post-treatment, and scored functionally, using the Toronto Active Motion Scale, and objectively, using an EMG device utilized to obtain the percentages of degeneration of the deltoid and the biceps muscles. Post-treatment values of six out of nine measured variables, between the two groups, revealed significant difference in favor of group B. The obtained results strongly support the introduction of kinesiotaping of the deltoid and the forearm as an adjunct to the treatment program of Erb’s palsied children.

[Management of post-term neonates]

OBJECTIVE

To estimate the modalities of management of post-term neonates.

METHODS

This study is based on PubMed search, Cochrane library and HAS recommendations.

RESULTS

Medical team should be able to provide neonatal resuscitation in delivery room in case of meconium-stained fluid or perinatal asphyxia according to the international guidelines ILCOR 2010. The glycaemia of the post-term newborn with macrosomia should be evaluated. The initial clinical examination should search complications such as shoulder dystocia or clavicular fracture. Full blood count should be performed in symptomatic newborn post-term. Developmental assessment should be performed in post-term newborn in case of associated pathology.

CONCLUSIONS

The risk of perinatal complications is increased in newborn post-term in delivery room and during hospitalization. Medical team should be able to manage these complications.

Reducing the risk of shoulder dystocia and associated brachial plexus injury

Despite persisting controversy over shoulder dystocia prediction, prevention, and injury causation, the authors find considerable evidence in recent research in the field to recommend additional guidelines beyond the current American College of Obstetricians and Gynecologists and Royal College of Obstetricians and Gynecologists guidelines to improve clinical practice in managing patients at risk for experiencing shoulder dystocia. In this article, the authors offer health care providers information, practical direction, and advice on how to limit shoulder dystocia risk and, more importantly, to reduce adverse outcome risk.

Evaluation of bone mineral density in children with perinatal brachial plexus palsy: effectiveness of weight bearing and traditional exercises

PURPOSE

(1) To investigate any evidence of bone mineral density (BMD) changes in children with Perinatal Brachial Plexus Palsy (PBPP). (2) To detect any relationship between these changes and the child age, weight, height, BMI, power index, gender, ethnicity, and the side affected. (3) To determine any possible effects of a designed weight bearing exercise program and the traditional one upon BMD of those children.

STUDY DESIGN

Randomized single blind controlled trial.

METHOD

A convenience sampling strategy was used to obtain 45 children with unilateral PBPP. Their ages ranged from 3 to 10 years. They were randomly divided to three equal groups. Groups were, then, randomly assigned to either interventions [Weight Bearing Exercises Program (WBEP) or Traditional Exercises Program (TEP)] or to the control treatment. Dual Energy X-Ray Absorptiometry (DXA) was used to evaluate BMD for all children at entry and approximately after six months treatment period.

RESULTS

We detected significant low entry level measurements of all BMD parameters of the affected side when compared to that of the unaffected sides (p=0.000). The mean value of the entry level calculated Z score for the affected side of all study children was equal to -1.12 ± 0.327 being in the osteopenic risk range. Furthermore, thirty children (66.7%) recorded less than (-1) Z score being in this risky range. Also, we recorded a significant improvement of all BMD parameters of the affected side after treatment in favor of the WBEP group when compared to that of the control and TEP groups (p=0.02, p=0.03 respectively for the affected both bones BMD parameter).

CONCLUSIONS

BMD is significantly reduced in PBPP children. The retardation of bone accrual increases as the child height and weight decreases and the degree of paralysis increases. WBEP significantly promoted BMD improvement when compared to the TEP.

Delivery after previous cesarean: long-term outcomes in the child

In subsequent pregnancies after a cesarean delivery, women must choose between attempting to deliver vaginally or undergoing another cesarean delivery. Information relevant to this choice includes the long-term benefits and harms to the baby. In this article we discuss the relationship of mode of delivery (planned trial of labor, either with or without vaginal delivery, or elective repeat cesarean delivery) and long-term outcomes, including brachial plexus palsy, neurodevelopmental impairment, and asthma. No randomized trials are available that relate directly to the choice of delivery method after previous cesarean. Observational studies suggest that cesarean delivery might be associated with a greater risk of asthma, caused perhaps by altered gut colonization, increased risk of neonatal respiratory disease, decreased gestational age at birth or decreased likelihood of breastfeeding. By contrast, vaginal delivery after a previous cesarean delivery is associated with greater risks of neurodevelopmental impairment and upper-extremity motor impairment, caused, respectively, by greater risks of perinatal hypoxic-ischemic encephalopathy and brachial plexus injury. Available information does not provide a precise estimate of the relative risks for infants delivered after a trial of labor versus elective cesarean delivery.
