Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
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.
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...
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...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

Area of Science:

  • Dermatology
  • Epidemiology
  • Clinical Research

Background:

  • Rosacea is a common chronic facial skin condition with unknown causes.
  • Limited epidemiological data exists for rosacea in North Africa, particularly Tunisia.
  • Understanding rosacea's prevalence and characteristics in diverse populations is crucial.

Purpose of the Study:

  • To determine the epidemiological and clinical features of rosacea in Tunisia.
  • To analyze treatment outcomes and histological findings for rosacea patients.
  • To address the scarcity of North African data on this dermatosis.

Main Methods:

  • A retrospective analysis of 244 rosacea cases diagnosed between 1990 and 2003.
  • Data collected from the Dermatology Department of Charles Nicolle hospital in Tunis.
  • Diagnosis based on clinical presentation and histological examination.

Main Results:

  • Hospital prevalence of rosacea was 0.2%, predominantly affecting middle-aged women (M/F ratio 0.4).
  • Papulopustular rosacea (69%) was the most frequent subtype, with sun exposure as a common trigger.
  • Ocular rosacea occurred in 41 cases; granulomatous and steroid-induced rosacea were also noted.

Conclusions:

  • Rosacea appears prevalent in Tunisia, particularly among individuals with skin types IV-V.
  • Papulopustular rosacea is the dominant subtype in this Tunisian cohort.
  • Further epidemiological and clinical studies in North Africa are recommended to validate these findings.
