Absorption of Nasal and Bronchial Fluids: Precision Sampling of the Human Respiratory Mucosa and Laboratory Processing of Samples
Published on: January 21, 2018
Abstract:
Aspergillosis is becoming an increasingly recognized pathogen in the sinonasal tract. The courses of two patients, one seemingly healthy and one with a terminal malignancy, are reviewed. These patients illustrate the clinical course, difficulties in diagnosis, and management of patients with aspergillosis of the sinonasal tract. Aspergillus is a common endogenous contaminant of the upper respiratory tract; however, bacterial sinusitis may trigger its growth and proliferation. Aspergillus fumigatus is the most common species implicated in paranasal sinus disease in the United States. The maxillary antrum is the most commonly involved site in the paranasal sinuses. Originally, aspergillosis was described in healthy patients, but it has become increasingly recognized in the immunocompromised and the chronically debilitated. Paranasal sinus Aspergillus infections are classified as non-invasive and fulminant. The treatment is primarily surgical. Antifungal chemotherapeutic agents are used in the treatment of central nervous system involvement and in the fulminant form of the disease.
Insights
Aspergillosis, a fungal infection, is increasingly seen in the sinonasal tract. Management involves surgical treatment, with antifungals used for severe cases.
Area of Science:
- Otorhinolaryngology
- Mycology
- Infectious Diseases
Background:
- Aspergillosis is an emerging pathogen in the sinonasal tract.
- Bacterial sinusitis can promote the growth of Aspergillus, a common contaminant.
- Aspergillus fumigatus is the most frequent species causing paranasal sinus issues in the U.S.
Observation:
- Two patient cases, one healthy and one with malignancy, highlight diagnostic and management challenges.
- The maxillary antrum is the most commonly affected sinus site.
- Infections are categorized as non-invasive or fulminant.
Findings:
- Aspergillosis is increasingly identified in immunocompromised and debilitated individuals.
- Surgical intervention is the primary treatment modality.
- Antifungal agents are reserved for central nervous system involvement and fulminant disease.
Implications:
- Understanding the varied clinical presentations of sinonasal aspergillosis is crucial for timely diagnosis.
- Effective management strategies require a combination of surgical and medical approaches.
- Further research into risk factors and preventative measures for sinonasal aspergillosis is warranted.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
