American Trypanosomiasis01:22

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
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...
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...
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...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Summary
This summary is machine-generated.

Tropical pyomyositis, a bacterial muscle infection, predominantly affects males and children, with lower limb abscesses being most common. Patient demographics remained consistent between 1980-1989 and 1995-2005 in rural Ecuador.

Area of Science:

  • Infectious Diseases
  • Tropical Medicine
  • Musculoskeletal Infections

Background:

  • Pyomyositis is a bacterial infection characterized by abscess formation within skeletal muscle.
  • Tropical pyomyositis is a distinct clinical entity often seen in tropical regions, with varying epidemiological patterns.
  • Understanding the demographics and clinical features of pyomyositis is crucial for effective public health strategies.

Purpose of the Study:

  • To analyze the epidemiological and clinical characteristics of tropical pyomyositis in a rural Amazonian Ecuadorian population.
  • To compare patient profiles and clinical presentations between two distinct time periods (1980-1989 and 1995-2005).
  • To identify any significant changes in the disease's affected demographics or common sites over time.

Main Methods:

  • Retrospective analysis of 165 patients diagnosed with tropical pyomyositis.
  • Data collected from a hospital in rural Amazonian Ecuador.
  • Comparison of patient data from two decades: 1980-1989 and 1995-2005.

Main Results:

  • Pyomyositis was more prevalent in males than females.
  • Children were more frequently affected than adults.
  • The most common site for abscesses was the lower extremity.
  • No significant demographic shifts were observed between the two study periods.

Conclusions:

  • Tropical pyomyositis in this Ecuadorian cohort primarily affects young males, with a predilection for lower limb involvement.
  • The disease's epidemiological profile remained stable over a 25-year period in this specific region.
  • Continued surveillance is important for understanding and managing pyomyositis in tropical settings.
