Pain01:20

Pain

2.1K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Nociception01:44

Nociception

28.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

773
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Chronic Pancreatitis I: Introduction

918
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Summary

Gallbladder agenesis, a rare condition, can cause biliary pain and aerobilia without prior surgery. This case highlights the importance of considering congenital anomalies in diagnosing abdominal pain.

Area of Science:

  • Gastroenterology
  • Abdominal Imaging
  • Biliary System Anatomy

Background:

  • Right upper quadrant abdominal pain is a common clinical presentation with diverse etiologies.
  • Diagnostic challenges arise when symptoms are atypical or suggest uncommon pathologies.
  • Biliary tract abnormalities can manifest with varied clinical signs and symptoms.

Purpose of the Study:

  • To report a rare case of gallbladder agenesis presenting with biliary-type pain and aerobilia.
  • To emphasize the diagnostic considerations for congenital gallbladder anomalies.
  • To highlight aerobilia as a potential sign in the absence of biliary intervention.

Main Methods:

  • Case report of a young female patient with right upper quadrant pain.
  • Clinical evaluation including history, physical examination, and diagnostic imaging.
Keywords:
AgenesisBiliary painGall bladder

  • Review of relevant literature on gallbladder agenesis and aerobilia.

    • Main Results:

    • The patient presented with symptoms suggestive of biliary colic.
    • Imaging revealed the absence of the gallbladder (gallbladder agenesis).
    • Presence of aerobilia (air in the biliary tree) was noted without prior biliary procedures.

    Conclusions:

    • Gallbladder agenesis is a rare congenital anomaly that can mimic common biliary pathologies.
    • Aerobilia in the absence of prior intervention warrants investigation for underlying anomalies like agenesis.
    • This case underscores the importance of comprehensive diagnostic evaluation for challenging abdominal pain presentations.
