Spina Bifida What is Spina Bifida: Spina Bifida literally means “split spine.” Spina Bifida happens when a baby is in the womb and the spinal column does not close all of the way3 Types of SB:• Occult Spinal Dysraphism• Spina Bifida Occulta• Myelomeningocele

Epidemiology Of Spina Bifida
• 1 out of 1,000 infants in us born with Spina Bifida
• 90-95% of babies born with Spina Bifida are born to parents with no family history of Spina Bifida
• Most common in girls than boys
• Most common neural tube defect

Spinal Cord Injury
What is Spinal Cord Injury A spinal cord injury begins with a sudden, traumatic blow to the spine that fractures or dislocates vertebrae.
Types of SCI
• Complete
• Incomplete

Epidemiology Of Spinal Cord Injury• It is estimated that the annual incidence of spinal cord
injury is approximately 40 cases per million population in the U. S. or approximately 12,000 new cases each year
-the average age at injury was 28.7 years-most injuries occur between the ages of 16 and 30-80.6% of spinal cord injuries occur among males-most common cause of SCI is falls, followed by acts of violence

Urinary Tract Infection(UTI)What is UTI:
• UTI occurs when organisms in bladder cause infection
▫ >10,000 CFU in a catheterized sample▫ >100,000 CFU in clean catch
AND Fever Dysuria (painful urination) Frequency Back pain White blood cells in the urine
• Bacteria are the most common cause of UTIs.

Organisms Associated With UTI• E coli (is the most common causing 75-90% of
UTI)• Klebsiella species• Proteus species• Enterococcus species• Staphylococcus saprophyticus• Staph aureus• Fungal in immune compromised patients

Risk Factors1. Bacterial virulence
2. Host factors :Anatomical:• Abnormal insertion of ureters in the bladder.• Urinary tract obstruction caused by phimosis, meatal
stenosis • Indwelling catheter
Functional: • *Neurogenic bladder in spina bifida patients and spinal
cord injuryImmunologic • Immune deficiency

Antibiotic Sensitivity Antibiotic sensitivity is the susceptibility of bacteria to antibiotics. The AST test is usually carried out to determine which antibiotic will be most successful in treating a bacterial infection in vivo. Testing for antibiotic sensitivity is often done by the Kirby-Bauer method. The ranges include:• Susceptible: organisms exposed to antibiotic with a high
likelihood of therapeutic success.• Intermediate : organisms exposed to antibiotic with an
uncertain therapeutic effect.• Resistant: organisms are able to survive after exposure to one or
more antibiotics

MedicationThese are the common Antibiotics used to treat UTI, they prevent complications of infections such as kidney damage. Most antibiotics come in pill or liquid form

Purpose and Objectives
• The purpose of the study was to examine organisms associated with UTI in the population of children with SB and SCI who were treated in out-patient and in-patient settings
• Public health significance: Knowledge of the causative organisms associated with UTI in patients with SB and SCI is of public health significance to promote appropriate use of antibiotics and reduce kidney damage

Hypothesis•Children with spinal cord injury and spina
bifida have a larger variety of organisms causing UTI than in the general population
•Organisms causing UTI in Children with spinal cord injury and spina bifida will have more resistance
![Page 20: Urinary Tract Infection In Children With Spina Bifida And Spinal Cord Injury](https://reader036.vdocuments.us/reader036/viewer/2022062412/5899dcd61a28ab4a0b8b6e3d/html5/thumbnails/20.jpg)
Method• A retrospective record review was conducted to extract data
from medical records and a pre-existing data base of in-patients and out-patients with SB and SCI who were diagnosed with UTI.
• Medical records from 2010-2013 were reviewed
• Data on demographics (e.g., gender, age, and race/ethnicity), medical condition, medication, and organism responsible for UTI, organism antibiotic resistance, hospital status input & output will be obtained.
• Chi square analysis was done to determine if there were statistically significant differences in the organisms infecting children with SCI versus SB.

There were no statistically significant differences in the organisms infecting children with SCI compared to SB (Pearson chi2 (5) =7.1803; P = 0.0208).

Conclusion And Public Health Significance
• E. coli is the leading cause of UTI in our study. • Contrary to the study’s of hypothesis, the susceptibility of the
bacteria to commonly used antibiotics is good.• It is also recommended that proper sensitivity testing of Urinary
tract infection causing organisms should be undertaken to guide the management of UTIs until the development of conclusive local guidelines to therapy.
• Using antibiotic susceptibility data assists pediatric providers in using appropriate first line antibiotics when children present with symptoms of urinary tract infection.
