Summary
Pediatric pulmonary blastomycosis commonly presents as consolidation with nodules and reticulonodular opacities. Radiography and CT show excellent concordance in identifying key imaging features.
Area of Science:
- Medical Imaging
- Pediatric Pulmonology
- Infectious Diseases
Background:
- Pulmonary blastomycosis is a fungal infection affecting the lungs.
- Pediatric cases present unique radiologic challenges.
- Updated characterization of imaging patterns is crucial for diagnosis.
Purpose of the Study:
- To characterize and update radiologic patterns of pediatric pulmonary blastomycosis.
- To correlate these patterns with patient age.
- To assess concordance between radiography and CT findings.
Main Methods:
- Retrospective analysis of chest imaging in 36 pediatric patients (0-18 years) with pulmonary blastomycosis (2005-2016).
- Data collected included age, sex, clinical information, and imaging findings.
- Concordance between radiography and CT was analyzed.
Main Results:
- Consolidation was the most common finding (94.4%), often unilateral.
- Associated findings included nodules (50%), reticulonodular patterns (41.2%), and pleural effusion (20.6%).
- Younger children (<5 years) showed multi-lobar consolidations; excellent concordance between radiography and CT was observed.
Conclusions:
- The most frequent pattern is consolidation with bilateral lung nodules and reticulonodular opacification.
- Radiologic findings vary with age, with younger children exhibiting more diffuse disease.
- Imaging plays a vital role in diagnosing and monitoring pediatric pulmonary blastomycosis.

01:06Fixed Action Patterns
17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

01:26Pharmacokinetics in Pediatric Patients: Drug Excretion
261
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

01:17Pharmacokinetics in Pediatric Patients: Drug Distribution
304
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

01:24Pharmacokinetics in Pediatric Patients: Drug Metabolism
223
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

01:29Pulmonary Tuberculosis I
953
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
