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...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Hepatitis01:25

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Hyperosmolar Hyperglycemic State01:21

Hyperosmolar Hyperglycemic State

Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...

    Area of Science:

    • Medical Parasitology
    • Infectious Diseases
    • Public Health

    Background:

    • Echinococcus granulosus infection, or hydatid disease, presents a significant parasitic challenge.
    • Understanding its epidemiology and clinical manifestations is crucial for effective management.

    Purpose of the Study:

    • To present detailed case reports of Echinococcus granulosus disease.
    • To survey and analyze cases encountered in Toronto hospitals.
    • To describe the epidemiological and clinical features of the disease in this population.

    Main Methods:

    • Review of two detailed case reports.
    • Survey of 35 Echinococcus granulosus disease cases from Toronto hospitals (1932-present).
    • Analysis of patient origin, affected organs, lesion multiplicity, diagnostic test results, and allergic manifestations.

    Main Results:

    • 35 cases of Echinococcus granulosus disease identified, with a surge since 1949.
    • Liver (20/35) and lung (16/35) were the most common sites of infection.
    • Diagnostic tests showed variable positivity: Casoni skin test (14/21), complement fixation test (13/16), and eosinophilia (9/26).

    Conclusions:

    • Echinococcus granulosus disease presents with varied clinical and epidemiological patterns.
    • Diagnostic tools like skin and serological tests, alongside eosinophilia, aid in diagnosis.
    • The study underscores the importance of considering this parasitic infection in relevant patient populations.
