Periprocedural antibiotics for urodynamic studies of pediatric neurogenic bladder, empiric or culture-guided? A retrospective cohort study.

INTRODUCTION: Urodynamic studies are fundamental in the care of children with neurogenic bladder. Children with neurogenic bladder who perform clean intermittent catheterization (CIC) are considered a high-risk group for infection after urodynamic studies. Current guidelines are not uniform regarding the duration, type, the need of prophylactic antibiotic treatment or performance of urine culture before urodynamic studies. OBJECTIVE: To assess whether antibiotic prophylactic therapy before urodynamic studies should be empiric or culture-guided in children with neurogenic bladder who perform CIC. STUDY DESIGN: Urine samples were collected from children with neurogenic bladder who require CIC before undergoing a urodynamic study. Urine cultures were collected via sterile urethral catheterization one week before urodynamic studies between 2010 and 2018. Children with signs of urinary tract infection (UTI) or children with bladder augmentation were excluded. Resistance to commonly prescribed periprocedural antibiotic treatments was documented. The probability of antibiotic resistance according to sex, vesicoureteral reflux (VUR) status, consumption of prophylactic antibiotics, and self/caregiver performed CIC was determined by a χ2-test. RESULTS: A total of 278 urine cultures were collected from 185 children with neurogenic bladder. The median age was 8 years (IQR 5-12). The most common etiology for neurogenic bladder was spinal dysraphism (n = 146, 77%). Bacterial growth was detected in 216 (78%) cultures, and the most commonly detected bacterial species was Escherichia. coli (n = 155, 72%). Thirty-six (19%) children had VUR, and 14 of them received continuous prophylactic antibiotics. The probability of resistance to oral antibiotics was amoxicillin (22%), cephalexin (21%), cefuroxime (14%), ciprofloxacin (10%), nitrofurantoin (21%), and sulfamethoxazole/trimethoprim (SMX/TMP) (23%) (See "summary table") No significant differences were found by χ2-test in the probability of resistance to antibiotics according to sex, VUR status, continuous antibiotic prophylaxis or self/caregiver performed CIC. DISCUSSION: The study reveals high resistance level to commonly prescribed oral antibiotic treatments (20-30%). Several studies have challenged the need of routine urine cultures before urodynamic studies due to low risk of post-procedural infection. However, it should be mentioned that not all the patients participating in those studies were with neurogenic bladder or routinely performed CIC. Hence, in this specific group of children, routine urine cultures should not be abandoned. The limitations of the study are: Single-center, retrospective study with no data availability regarding the development of UTI after the urodynamic studies. CONCLUSIONS: Urine cultures of children with neurogenic bladder who require CIC demonstrate significant levels of resistance to commonly prescribed oral antibiotics. These findings support culture-guided periprocedural antibiotic prophylaxis.

Asymptomatic bacteriuria and antibiotic resistance profile in children with neurogenic bladder who require clean intermittent catheterization.

STUDY DESIGN: A retrospective cohort study. OBJECTIVES: To document the prevalence of asymptomatic bacteriuria and to characterize the resistance patterns to antibiotics among children with neurogenic bladder who require clean intermittent catheterization, with an emphasis on multidrug resistance. SETTING: A national referral pediatric and adolescent rehabilitation facility in Jerusalem, Israel. METHODS: Routine urine cultures were collected before urodynamic studies in suitable individuals during 2010-2018. None of them had symptoms of urinary tract infection at the time of specimen collection. Cultures were defined as being positive if a single bacterial species was isolated together with a growth of over 105 colony-forming units/ml. Resistance patterns were defined as extended-spectrum beta-lactamase (ESBL) and resistant to 3 antimicrobial groups (multi-drug resistant, MDR). RESULTS: In total, 281 urine cultures were available for 186 participants (median age 7 years, range 0.5-18). Etiologies for CIC included myelomeningocele (n = 137, 74%), spinal cord injury (n = 16, 9%) and caudal regression syndrome (n = 9, 5%). Vesicoureteral reflux was diagnosed in 36 participants (19%), 14 of whom were treated with prophylactic antibiotics. Asymptomatic bacteriuria was present in 217 specimens (77%, 95%CI [0.72-0.82]). The bacteria species were E. coli (71%), Klebsiella (13%), and Proteus (10%). ESBL was found in 11% of the positive cultures and MDR in 9%, yielding a total of 34 (16% of positive cultures) positive for ESBL and/or MDR bacteria. CONCLUSIONS: Asymptomatic bacteriuria and resistance to antimicrobials are common in pediatric individuals who require CIC.

Exploring hand dexterity in children with myelomeningocele.

PURPOSE: To assess hand dexterity in children with myelomeningocele (MMC) and to explore factors related to hand dexterity in these children. METHODS: Ninety-four children with myelomeningocele, aged 4 to 18 years, were assessed. Demographic characteristics, disease factors, visual perception (Beery test of Visual Motor Integration), cognition (WeeFunctional Independence Measure), and self-care (Pediatric Evaluation of Disability Inventory) were assessed in relation to the Nine-Hole Peg Test (9HPT) for hand dexterity using Spearmen correlations and linear regressions. RESULTS: The children's performance on the 9HPT in both hands was significantly slower than the norms for their age groups. Children without a shunt showed significantly better function in both hands (p = .005) than those with a shunt. Factors most related to hand dexterity were neurological spinal level of MMC, presence of shunt, age, cognitive ability, and years of mother's education. CONCLUSION: Children with MMC appear to have poorer hand skills than typically developed children, which was related to pathology as well as functional and environmental factors. When addressing hand dexterity in children with MMC, it is important that rehabilitation professionals continue to work with these children as they get older, and put greater emphasis on parent education using materials that are adapted to varying educational levels.

Independence in self-care activities in children with myelomeningocele: exploring factors based on the International Classification of Function model.

PURPOSE: To investigate the relationship between disease factors, body functions and structures, activities, personal and environmental factors with independence in self-care activities in children with myelomeningocele (MMC), utilizing the International Classification of Function model. METHOD: 113 children with MMC, aged 3-18 years were assessed during an annual MMC-clinic visit. Data on the personal and environmental factors, disease factors, hand function, mobility, visual perception, cognition, and communication were assessed in relation to the Pediatric Evaluation of Disability Inventory (PEDI) self-care domain. RESULTS: The mean PEDI caregiver assistance score was 22.1 (ranged between <10 and 62) well below the norms. The most significant determinant of dependence in self-care activities was the presence of hydrocephalus, a child with hydrocephalus scored a mean of 9.2 points less on the PEDI caregiver scale (p = 0.02). By using a linear regression, the most significant factors associated with the PEDI scores among children with hydrocephalus were the age of the child, function of the non-dominant hand, ambulation, and cognitive function. CONCLUSION: In children with MMC the presence of hydrocephalus appears to be more significantly associated with functional independence than the neurological level. The International Classification of Function model provides an in-depth multidisciplinary model that facilitates in investigating independence in self-care activities in children with MMC. It is important to take personal factors and various functional impairments into account when working with these children to promote independence. Implications for Rehabilitation When working with children with myelomeningocele on independence in daily living activities, it is necessary that health professionals demonstrate a holistic view of the child and his/her disability. Health professionals should take into account information on all factors of the International Classification of Function, in order to help the children, achieve maximal independence. It is important for health professionals to consider presence or lack of hydrocephalus when working with children with myelomeningocele to achieve functional gains. Improving upper extremity function and cognitive ability in children with myelomeningocele may help promote independence in activities of daily living. It is necessary for health professionals to continue to work with children with myelomeningocele on maximizing independence as they get older, for it is possible for them to achieve independence at a later age. While this study did not explore participation, this is an essential part of the International Classification of Function and is generally related to function. Participation allows a child to be involved in life situations, contributes to life satisfaction and prepares children for critical adult roles. It is therefore important to assess and monitor this measure. Further studies should examine associations between independence in self-care activities and participation.
