Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

6.6K
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...

Pharynx01:20

Pharynx

8.3K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Suctioning the Oropharyngeal Airway

1.3K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Oral Cavity01:11

Oral Cavity

3.6K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Esophagus01:24

Esophagus

4.4K
The esophagus, a muscular conduit linking the pharynx and stomach, measures roughly 10 inches (25.4 cm) and sits behind the trachea. It remains collapsed when not swallowing. The esophagus follows a predominantly straight path through the thoracic mediastinum and enters the abdominal cavity through a diaphragmatic opening known as the esophageal hiatus.
The movement of edibles from the pharynx into the esophagus is facilitated by the upper esophageal sphincter, which is formed primarily by the...

    Summary
    This summary is machine-generated.

    Positron emission tomography-CT scans are not typically used for initial Diffuse Large B-Cell Lymphoma staging. However, recent evidence supports their value in assessing treatment response and guiding risk-adapted therapy.

    Area of Science:

    • Oncology
    • Nuclear Medicine
    • Radiology

    Context:

    • Diffuse Large B-Cell Lymphoma (DLBCL) is the most common non-Hodgkin lymphoma.
    • The utility of CT/PET scans in initial DLBCL staging remains debated.
    • Current evidence suggests limited impact on initial patient management.

    Purpose:

    • To evaluate the evolving role of CT/PET in DLBCL management.
    • To explore the application of CT/PET in assessing treatment response.
    • To investigate the potential for CT/PET in risk-adapted therapy strategies.

    Summary:

    • CT/PET scans have a controversial role in the initial staging of Diffuse Large B-Cell Lymphoma.
    • Recent publications and expert consensus highlight the utility of CT/PET for evaluating end-of-treatment response.
    • There is growing interest in using CT/PET during treatment for risk-adapted therapy.

    Impact:

    • This research informs the clinical application of CT/PET in DLBCL.
    • It supports a shift towards using CT/PET for response assessment rather than initial staging.
    • Findings contribute to the development of personalized treatment strategies for DLBCL patients.
