CaseBites: Pediatrics | Neonatal Jaundice

Host: Ahmad SabbahVoice Actor: Ibrahim Alodhaibi
This is CaseBites from PodBites—where we break down complex medical topics into bite-sized pieces.
In this episode, we explore neonatal jaundice, from normal physiologic bilirubin elevation to dangerous conditions like hemolysis, hepatobiliary disease, and kernicterus risk.
Learn how to evaluate bilirubin levels, distinguish conjugated vs unconjugated jaundice, and apply evidence-based management to protect the developing brain.
Because recognizing jaundice early prevents lifelong consequences.

CaseBites: Pediatrics | Endocrine Challenges in the Newborn

Host: Ahmad SabbahVoice Actor: Ibrahim Alodhaibi
Welcome to CaseBites from PodBites—where we break down complex medical topics into bite-sized pieces.
In this episode, we explore the Infant of a Diabetic Mother, focusing on complications such as macrosomia, hypoglycemia, congenital anomalies, and metabolic instability.
Understand how maternal physiology directly shapes neonatal outcomes, and how early recognition and management prevent serious complications.
High-yield knowledge for pediatric exams, OSCEs, and real clinical practice.

CaseBites: Pediatrics | Neurology & Catastrophic Neonatal Events

Host: Ahmad SabbahVoice Actor: Ibrahim Alodhaibi
This is CaseBites from PodBites—where we break down complex medical topics into bite-sized pieces.
In this episode, we tackle catastrophic neonatal emergencies, including Hypoxic-Ischemic Encephalopathy (HIE), Sudden Infant Death Syndrome (SIDS), and Neonatal Sepsis and Shock.
Learn how oxygen deprivation injures the neonatal brain, why therapeutic hypothermia is time-sensitive and lifesaving, and how early intervention prevents devastating outcomes.
Because in neonatal medicine, early recognition changes everything.

CaseBites: Pediatrics | Neonatal Respiratory Disorders

Host: Ahmad SabbahVoice Actor: Ibrahim Alodhaibi
Welcome back to CaseBites from PodBites—where we break down complex medical topics into bite-sized pieces.
In this episode, we explore respiratory disorders affecting full-term newborns, including Transient Tachypnea of the Newborn (TTN), Meconium Aspiration Syndrome (MAS), and Persistent Pulmonary Hypertension of the Newborn (PPHN).
Understand how these conditions develop, how to distinguish physiologic adaptation from life-threatening pathology, and how early recognition guides lifesaving management.
Essential listening for pediatric OSCEs, exams, and clinical rotations.

CaseBites: Pediatrics | Complications of Prematurity

Host: Ahmad SabbahVoice Actor: Ibrahim Alodhaibi
Welcome to CaseBites, the clinical case-based series from PodBites—where we break down complex medical topics into bite-sized pieces.
