Summary
Pulmonary alveolar microlithiasis (PAM) is a rare lung disease that can be difficult to diagnose. This case report highlights key diagnostic findings and management strategies for PAM.
Area of Science:
- Pulmonology
- Radiology
- Pathology
Background:
- Pulmonary alveolar microlithiasis (PAM) is an uncommon interstitial lung disease.
- Diagnostic challenges are frequently encountered in clinical practice.
- Early and accurate diagnosis is crucial for effective patient management.
Observation:
- A 45-year-old female presented with a two-year history of worsening dyspnea and dry cough.
- Previous diagnosis of pulmonary tuberculosis was ineffective.
- Referred to a tertiary care center for further evaluation.
Findings:
- High-resolution computed tomography (HRCT) revealed characteristic findings of PAM.
- Bronchoalveolar lavage (BAL) demonstrated abundant lamellar microliths.
- Diagnosis of PAM was confirmed based on imaging and pathological findings.
Implications:
- This case underscores the importance of considering PAM in patients with unexplained respiratory symptoms.
- HRCT and BAL are valuable tools for diagnosing PAM.
- Symptomatic management and pulmonary rehabilitation are key components of care for PAM patients.

03:24Common Ion Effect
46.8K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

01:26Alveoli and Alveolar Ducts
5.8K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

01:31Common Respiratory Disorders
1.4K
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

01:19Mass Analyzers: Common Types
1.6K
The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...

01:11Common Names of Aldehydes and Ketones
5.0K
Some common aldehydes and ketones are popularly known by their common names used historically and predate the IUPAC nomenclature.
Common names of aldehydes are derived from the names of their corresponding acid. For instance, the two-carbon aldehyde–acetaldehyde derives its name from the corresponding acid–acetic acid. Similarly, formaldehyde derives its name from formic acid and benzaldehyde from benzoic acid.
Aliphatic ketones are named by suffixing the word “ketone” to the...
