Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

136
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Diseases of the Liver and Gallbladder

334
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.7K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Cystic Fibrosis: Management01:24

Cystic Fibrosis: Management

94
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

52
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...

Sex-linked Disorders01:43

Sex-linked Disorders

98.0K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Area of Science:

  • Pediatric Neurology
  • Neurodevelopmental Disorders
  • Medical Imaging

Background:

  • A 10-month-old infant presented with progressive macrocephaly, axial hypotonia, developmental delay, and limb stiffness.
  • Clinical presentation included delayed motor milestones (head control, sitting) and lack of babbling.
  • Neurological examination indicated poor visual contact, spastic diplegia features, but no swallowing difficulties or seizures.

Purpose of the Study:

  • To investigate the underlying cause of severe neurodevelopmental delay and macrocephaly in an infant.
  • To utilize advanced neuroimaging techniques for diagnostic assessment.

Main Methods:

  • A 10-month-old female infant underwent a comprehensive neurological examination.
  • Brain magnetic resonance imaging (MRI) was performed using a 3-Tesla scanner.
  • Morphologic sequences and spectroscopy were acquired, with and without gadolinium contrast.

Main Results:

  • The infant exhibited significant developmental delays and progressive macrocephaly.
  • Neurological findings were suggestive of spastic diplegia.
  • Electroencephalographic monitoring showed no abnormalities.

Conclusions:

  • Advanced brain MRI, including spectroscopy, is crucial for diagnosing complex pediatric neurological conditions.
  • Further investigation is warranted to determine the specific etiology of the observed symptoms.
