[Persistent, therapy-resistant conjunctivitis: consider infection with Chlamydia trachomatis]
Nederlands Tijdschrift Voor Geneeskunde
|April 27, 2017
Summary
Persistent conjunctivitis in older adults can be a sign of chlamydia infection. Early diagnosis and treatment with azithromycin are crucial, even in elderly patients, to prevent complications.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Conjunctivitis is common, often viral, but chlamydial infections can be overlooked.
- Chlamydial conjunctivitis in the elderly may present atypically, leading to delayed diagnosis.
Observation:
- Two elderly patients presented with persistent, therapy-resistant conjunctivitis.
- One patient exhibited conjunctival follicles, a potential indicator of chlamydial infection.
Findings:
- Polymerase chain reaction (PCR) tests confirmed chlamydia in conjunctival samples from both patients.
- Both patients and their sexual partners responded to oral azithromycin treatment.
Implications:
- Chlamydial conjunctivitis should be considered in persistent, therapy-resistant cases, regardless of patient age.
- Prompt diagnosis and treatment are essential to avoid complications associated with chlamydial infections.

01:29Bacterial Phylum Chlamydiae
674
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:28Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

13.5K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
