Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
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,...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Brain Abscess l: Introduction01:26

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,...

Area of Science:

  • Parasitology
  • Ophthalmology
  • Surgical Pathology

Background:

  • Dirofilariasis is a parasitic infection typically affecting animals, with human cases being uncommon.
  • Deep tissue dirofilariasis is exceptionally rare, with limited documentation in medical literature.
  • Orbital abscesses can arise from various infectious sources, including sinusitis.

Purpose of the Study:

  • To report a rare case of deep tissue dirofilariasis presenting as an orbital abscess.
  • To highlight the diagnostic and therapeutic approach for this unusual presentation.
  • To emphasize the importance of considering parasitic infections in complex orbital pathologies.

Main Methods:

  • A 58-year-old female patient presented with symptoms of right orbital abscess and ethmoid sinusitis.
  • Diagnostic evaluation included clinical examination and imaging (details not provided in abstract).
  • Surgical intervention involved endoscopic ethmoidectomy with abscess drainage for worm extraction.

Main Results:

  • A Dirofilaria worm was successfully extracted during the endoscopic ethmoidectomy procedure.
  • The patient's orbital abscess was treated effectively through surgical removal of the parasite.
  • No anti-parasitic medications were required for successful treatment.

Conclusions:

  • Surgical excision of the Dirofilaria worm is the primary treatment for deep tissue dirofilariasis.
  • This case underscores the importance of considering zoonotic parasitic infections in orbital diseases.
  • Endoscopic sinus surgery can be a valuable approach for diagnosing and treating such rare conditions.
