Summary
Tubercular sternal osteomyelitis, a rare form of tuberculosis, can mimic other serious conditions. This case highlights the importance of considering tuberculosis in chest wall masses, even with initial misdiagnoses.
Area of Science:
- Medicine
- Infectious Diseases
- Orthopedics
Background:
- Tubercular sternal osteomyelitis is an uncommon presentation of tuberculosis.
- It can present with symptoms mimicking other sternal pathologies, leading to diagnostic challenges.
Purpose of the Study:
- To report a case of tubercular sternal osteomyelitis.
- To emphasize the differential diagnosis in sternal masses.
Main Methods:
- Case report of a 51-year-old male patient.
- Clinical presentation of central chest wall pain and swelling.
- Initial misdiagnosis as chondrosarcoma of the sternum.
Main Results:
- The patient presented with a three-month history of chest wall pain and swelling.
- The initial clinical diagnosis was chondrosarcoma of the sternum.
Conclusions:
- Tubercular sternal osteomyelitis should be considered in the differential diagnosis of sternal lesions.
- Accurate diagnosis is crucial for appropriate management and treatment of tuberculosis affecting the sternum.

Lytic Cycle of Bacteriophages
78.2K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

Viral Replication: Lytic Cycle
1.7K
Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...

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.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

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:
