Rocky Mountain Spotted Fever

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.

Leishmaniasis

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis I

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.
Mode of...

Summary

Sarcoidosis is rarely reported in Senegal, unlike other populations. This study characterized sarcoidosis cases in Dakar, revealing predominantly systemic disease with polymorphous clinical features.

Area of Science:

Pulmonology
Dermatology
Rheumatology

Context:

Sarcoidosis is a multisystem granulomatous disease with variable prevalence globally.
Rare cases of sarcoidosis have been documented in Senegal, despite its high incidence in individuals of African descent.
Understanding sarcoidosis epidemiology in West Africa is crucial for diagnosis and management.

Purpose:

To determine the epidemiological, clinical, and evaluative profile of sarcoidosis in Dakar, Senegal.
To investigate the characteristics of sarcoidosis cases in a region with limited reported data.

Summary:

A retrospective study analyzed 20 sarcoidosis cases (21 female, 9 male) in Dakar from 1968 to 2004.
The average age was 40, with a median delay of one year for diagnosis.
Sarcoidosis presented as systemic disease in 76% of cases, with pulmonary (73.33%) and lymphadenopathy (66.66%) as common extra-cutaneous manifestations. Cutaneous lesions were observed in 66.66% of patients.
Pulmonary tuberculosis was a co-morbidity in 4 cases, highlighting the need for differential diagnosis.

Impact:

This study highlights the rarity of sarcoidosis in Senegal compared to other populations of African descent.
The findings underscore the polymorphous clinical presentation and predominant systemic nature of sarcoidosis in this region.
Emphasizes the importance of ruling out tuberculosis to prevent misdiagnosis in sarcoidosis patients.
