Summary
Primary ciliary dyskinesia (PCD) is a rare genetic disorder affecting cilia function. Early diagnosis of PCD is crucial for managing symptoms like chronic cough and preventing lung damage.
Area of Science:
- Genetics
- Respiratory Medicine
- Cell Biology
Background:
- Primary ciliary dyskinesia (PCD) is an autosomal recessive genetic disorder affecting motile cilia.
- Affecting approximately 1 in 20,000 live births, PCD can lead to situs inversus in 50% of cases (Kartagener's syndrome).
- Symptoms include chronic rhinosinusitis, otitis media, bronchiectasis, infertility, and a persistent chronic cough.
Purpose of the Study:
- To highlight the diagnostic challenges of PCD, particularly in cases without situs inversus.
- To emphasize the importance of early diagnosis for preventing disease progression.
- To outline current diagnostic criteria and potential screening methods for PCD.
Main Methods:
- Diagnosis relies on characteristic clinical phenotypes combined with specific ciliary ultrastructural defects (via transmission electron microscopy) or genetic mutation identification.
- Nasal nitric oxide concentration measurement is a potential screening tool due to extremely low levels in PCD patients.
- Review of clinical presentations and diagnostic approaches for PCD.
Main Results:
- PCD diagnosis is complex, especially in individuals without situs inversus, leading to potential underdiagnosis.
- Chronic cough is a significant and common symptom across most PCD patients.
- Low nasal nitric oxide levels show promise as a screening biomarker for PCD.
Conclusions:
- Early diagnosis of PCD is vital to prevent irreversible lung damage like bronchiectasis and preserve lung function.
- Management strategies include lifestyle guidance, vaccinations, smoking cessation, and prompt infection treatment.
- Genetic counseling is recommended for families affected by this autosomal recessive condition.

5.8K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

1.1K
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,...

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.

2.0K
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

01:22Microtubules in Signaling
2.3K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
