This document outlines diagnostic tests for different age groups to assess auditory function in children. It describes behavioral observation for infants 0-6 months, visual reinforcement audiometry for children 6-30 months to estimate hearing sensitivity, and conditioned play audiometry for children 30 months to 4 years to determine frequency-specific hearing thresholds. Speech audiometry is recommended for children 6 months and older to assess speech perception abilities. Physiologic tests like immittance testing, otoacoustic emissions, and auditory brainstem response are also described. The appropriate test battery is individualized for each child based on their age and development.
Auditory brainstem response (ABR)
Approximately 1 of every 1000 children is born deaf. Many more are born with less severe degrees of hearing impairment, while others may acquire hearing loss during early childhood.

Overview of Behavioural and Objective Techniques in Screening.pptxAmbuj Kushawaha
Hearing loss, being an invisible disability, can remain unnoticed, particularly since typically developing children might not start speaking until around the age of two. Consequently, if hearing loss isn't identified through newborn hearing screening initiatives, it frequently remains undetected beyond 18 months of age, especially among children without any medical conditions or additional disabilities.
Assessing Hearing Loss in Infants and Young ChildrenValue Hearing
Although it’s often difficult to tell if your child is suffering from some hearing conditions or problems as it usually occurs gradually when the child is developing, there are screening and evaluation tests carried out to asses hearing in newborns and young children.

How do you test for auditory processing disorder?clearlyhearing73
Testing for auditory processing disorder typically involves a series of assessments conducted by audiologists or speech-language pathologists. These assessments may include behavioral tests, speech-in-noise tests, auditory memory tests, and other specialized evaluations to measure how the brain processes auditory information. Additionally, comprehensive evaluations of listening skills, language abilities, and cognitive function may be conducted. These tests help identify specific areas of difficulty and guide the development of individualized intervention plans to address auditory processing challenges.
This sildes shows the basic objective tests of pediatric audiological assessment.

CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

2. Introduction
◦ The American Academy of Audiology supports early identification, assessment, and
intervention for all types of hearing loss in infants and young children to minimize
deleterious effects on speech, language, education, and social/psychological development.
◦ These Clinical Practice Guidelines describe recommended practices for the assessment of
auditory function in children.
◦ The most appropriate protocol will be individualized for each child based on his or her
developmental and/or chronological age and other relevant factors. Thus, test procedures
needed to address this population are diverse.
◦ The scope-of-practice and responsibility of the audiologist is to determine the
appropriate test procedures to use for each child.
3. ◦ The Pediatric Hearing Assessment Task Force has delineated the following areas that make up the pediatric
audiologic assessment test battery:
◦ • Behavioral observation
◦ • Visual Reinforcement Audiometry (VRA)
◦ • Conditioned Play Audiometry (CPA)
Frequency-specific stimuli
Speech Audiometry
◦ Physiologic Assessments,
Acoustic Immittance, including tympanometry and acoustic reflex testing
Otoacoustic Emission (OAE) testing
◦ Electrophysiologic Audiometry including
Auditory Brainstem Response (ABR)
Auditory Steady State Response (ASSR) audiometry
4. Behavioral Observation
◦ Test Name:The term “audiometry” should be reserved for tests of hearing ability. Because this procedure does not
result in the determination of hearing thresholds, the term Behavioral Observation Audiometry or BOA is not
appropriate, and the preferred term is Behavioral Observation.
◦ Purposes:To assist in the determination of global auditory skill development. This method is inappropriate for
hearing screening or estimating auditory thresholds, or for selecting, modifying or verifying amplification.
◦ Populations Intended: 0-6 months
5. Visual Reinforcement Audiometry
◦ Test Name:Visual Reinforcement Audiometry (VRA)
◦ Purposes: Used to estimate frequency- and ear-specific hearing sensitivity and hearing loss type using a
conditioned response procedure.
◦ Populations Intended: 6-30 months
6. Conditioned Play Audiometry
◦ Test Name: Conditioned Play Audiometry (CPA)
◦ Purposes:To determine ear-specific and frequency-specific hearing sensitivity.
◦ Populations Intended: 30months – 4 years
7. Speech Audiometry
◦ Test names: Speech perception, speech audiometry
◦ Purpose:To determine ability to perceive speech or speech-like stimuli;
to aid in determination of pure tone threshold reliability;
includes speech awareness, speech discrimination, and speech recognition determinations
◦ Population Intended: children at and above approximately 6 months developmental age
8. Pediatric Immittance Testing
◦ Test names: Tympanometry and Acoustic Reflex Measures
◦ Purpose:To assess middle ear function and auditory pathway integrity; to evaluate for otitis media and other
middle ear abnormalities.
◦ Population intended: Infants and young children. Immittance assessment should occur routinely as a component of
the hearing evaluation, and more frequently for children at increased risk for middle ear disease or for those with
known sensorineural hearing loss, or at risk for auditory neuropathy

11. Otoacoustic Emissions
◦ Test name: Otoacoustic Emissions (OAEs). Currently, two types of evoked OAEs are used for clinical assessment:
transient-evoked OAEs (TEOAEs), elicited using an acoustic click or other short transient, and distortion product
OAEs (DPOAEs), elicited by the simultaneous presentation of two pure tones.
◦ 2. Purpose:To assess cochlear/outer hair cell function. Although not a direct measure of hearing, OAEs provide
information about the status of the auditory periphery and, in the absence of middle ear disorder, the likelihood of
sensory hearing loss. OAEs can be used as a screening procedure for hearing loss in neonates and infants, a cross-
check verification of behavioral testing when indicated, and/or to establish some aspects of cochlear function in
children with neural hearing loss. OAEs can also be used to monitor cochlear function in children undergoing
potentially ototoxic treatments (e.g., chemotherapy, aminoglycoside antibiotic therapy), although currently there
are no universally established criteria for the degree of change in OAEs considered to be clinically significant.
◦ 3. Population intended: Infants and children of all ages.
12. Electrophysiologic (EP) Evaluation
◦ Test names: Tone-burst (TB)-Auditory Brainstem Response (ABR) and Auditory Steady-State Response (ASSR).
◦ Purpose:To determine presence and type of hearing loss, and to estimate hearing levels for individual frequencies
in each ear.
◦ Population intended: Newborns and infants; a child of any age who is incapable of providing accurate information
for behavioral tests or who has yielded behavioral test results that are not reliable or are incomplete.
