Summary
This case highlights hereditary ciliary dyskinesia in an adult with bronchiectasis, deafness, and sinusitis. Nasal biopsies are crucial for diagnosing this condition by examining ciliary structure.
Area of Science:
- Pulmonology
- Genetics
- Otolaryngology
Background:
- Bronchiectasis in adults can stem from various causes, including genetic conditions.
- Hereditary ciliary dyskinesia (HCD) is a rare genetic disorder affecting cilia function.
- Early diagnosis of HCD is essential for managing associated respiratory and other symptoms.
Observation:
- A 26-year-old man presented with bronchiectasis, congenital deafness, purulent bronchorrhea, nasal polyps, dysmorphic features, and chronic sinusitis.
- The patient's brother exhibited similar symptoms, including congenital bronchiectasis, deafness, mental deficiency, and sinusitis, suggesting a familial pattern.
- Nasal biopsies revealed structural ciliary abnormalities, specifically a deficiency of the inner dynein arm.
Findings:
- The patient's clinical presentation and ciliary defect are consistent with Young's syndrome, a form of hereditary ciliary dyskinesia.
- The absence of situs inversus in this case differentiates it from primary ciliary dyskinesia (PCD).
- Hereditary ciliary dyskinesia should be considered in adults presenting with bronchiectasis and concurrent rhinologic or gastrointestinal issues.
Implications:
- Nasal biopsies are a safe and effective diagnostic tool for identifying ciliary abnormalities in suspected cases of HCD.
- Recognizing HCD in adults with bronchiectasis and related disorders can lead to timely diagnosis and management.
- This case underscores the importance of a comprehensive diagnostic approach for complex respiratory conditions in young adults.

01:23Cystic Fibrosis: Pathogenesis
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, but...

01:24Cystic Fibrosis: Management
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.

01:23The Bronchial Tree
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

01:23Chronic Obstructive Pulmonary Disease I: Introduction
Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
