Two cases of pulsatile tinnitus: Key points for the clinician
Summary
Pulsatile tinnitus can stem from serious underlying conditions like carotid artery dissection or hydrocephalus, even with normal ear exams. Prompt ENT evaluation is crucial for diagnosing and managing these potentially severe causes.
Area of Science:
- Otolaryngology
- Neurology
- Vascular Surgery
Background:
- Pulsatile tinnitus is an internal body sound perceived by the patient.
- It necessitates a thorough diagnostic approach beyond standard ENT evaluations.
Observation:
- Two cases of pulsatile tinnitus with normal otolaryngology (ENT) examinations are presented.
- Case 1 involved cervical internal carotid artery dissection.
- Case 2 involved hydrocephalus secondary to a craniopharyngioma compressing the foramina of Monro.
Findings:
- Pulsatile tinnitus can originate from significant vascular or neurological pathologies.
- These conditions may present insidiously despite normal initial ENT assessments.
Implications:
- Highlights the importance of a systematic management strategy for pulsatile tinnitus.
- Emphasizes the critical role of ENT clinicians in identifying potentially severe underlying conditions and complications.

Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

DNA in a human cell is almost 2m long and it is packed inside a tiny nucleus that is only a few microns in diameter. The level of compaction of DNA inside the nucleus is astonishing. It is organized into several sequentially higher levels of compaction to fit into such a tiny space. The most compact form of DNA is a chromosome that can be seen under a microscope in a dividing cell.

Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
