Summary
This study details the rare otopathology of temporal bone angiosarcoma, revealing cancer persistence post-treatment and pathways for meningitis development from chronic otitis media.
Area of Science:
- Otopathology
- Oncology
- Neuro-oncology
Background:
- Angiosarcoma of the temporal bone is a rare malignancy with poorly understood otopathology.
- Chronic otitis media may be a predisposing factor for temporal bone angiosarcoma.
Observation:
- A 50-year-old male with chronic otitis media developed progressive hearing loss and facial paresis due to a temporal bone angiosarcoma.
- Despite chemotherapy and radiation, postmortem examination revealed persistent angiosarcoma in the internal auditory canal.
Findings:
- Histological analysis demonstrated angiosarcoma within the temporal bone, extending into the internal auditory canal.
- Inflammatory infiltrates were observed extending from the mastoid into the cochlea and cranial cavity, indicating a pathway for meningitis.
Implications:
- This case highlights the aggressive nature of temporal bone angiosarcoma and the challenges in its treatment.
- Understanding these pathways is crucial for managing complications like meningitis in patients with temporal bone malignancies.

01:10¹H NMR of Labile Protons: Temporal Resolution
1.7K
Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum.

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:40Bone Remodeling
40.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:29Bone Disorders
5.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
