Abstract

Insights

Actinomycosis of the paranasal sinus, often presenting as unilateral maxillary sinusitis with calcified densities, typically responds well to surgical intervention and antibiotics, with no recurrence observed in this study.

Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Radiology

Background:

  • Actinomycosis is a rare bacterial infection that can affect various parts of the head and neck, including the paranasal sinuses.
  • Clinical presentation and optimal treatment strategies for paranasal sinus actinomycosis require further elucidation.

Purpose of the Study:

  • To describe the clinical features and treatment outcomes of patients diagnosed with actinomycosis affecting the paranasal sinus.

Main Methods:

  • A retrospective review of medical records was conducted.
  • Data from six patients with paranasal sinus actinomycosis diagnosed between 1998 and 2006 were analyzed.

Main Results:

  • All six patients were immunocompetent, and the lesions were unilateral.
  • CT scans revealed unilateral maxillary sinus opacification with focal calcified densities in all cases.
  • Endoscopic sinus surgery followed by short-term antibiotic therapy resulted in no recurrence.

Conclusions:

  • Key indicators of actinomycotic sinusitis include chronic unilateral maxillary sinusitis, calcified densities on imaging, and resistance to antibiotic therapy.
  • Surgical debridement of infected tissues and restoration of sinus drainage are crucial for successful treatment.

Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Nose and Nasal Cavity01:24

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
