    Insights

    Iron therapy improved ozena patients with low serum iron. Electron microscopy revealed connective tissue damage and ferruginous micelles in mitochondria, suggesting disrupted iron metabolism at the subcellular level.

    Area of Science:

    • Pathology
    • Biochemistry
    • Electron Microscopy

    Background:

    • Ozena (atrophic rhinitis) is a chronic nasal condition.
    • Patients often exhibit significantly lowered serum iron levels.
    • Iron therapy has shown positive outcomes in managing ozena symptoms.

    Purpose of the Study:

    • To investigate the pathogenesis of ozena.
    • To examine the effects of iron deficiency on nasal mucosa at a subcellular level.
    • To explore potential mechanisms of disturbed iron metabolism in ozena.

    Main Methods:

    • Electron microscopic examination of nasal mucosa from ozena patients.
    • Analysis of connective-tissue stroma and cellular structures.
    • Identification of intracellular deposits, specifically ferruginous micelles.

    Main Results:

    • Significant disintegration of the connective-tissue stroma in the nasal mucosa was observed.
    • Ferruginous micelles were identified within the mitochondrial matrix of connective-tissue cells.
    • These findings indicate structural changes at the subcellular level associated with the disease.

    Conclusions:

    • Subcellular mitochondrial deposits (ferruginous micelles) may represent a morphological manifestation of disturbed iron metabolism in ozena.
    • The observed tissue disintegration highlights the impact of iron dysregulation on nasal mucosa structure.
    • Further research into iron metabolism at the subcellular level is warranted for understanding ozena pathogenesis.

    Microbes and Other Elemental Cycles

    Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...
