KembaraXtra - Medical Terms - actinomycin D
Actinomycin D is another name for the chemotherapy drug dactinomycin. It is an antibiotic substance that interferes with DNA-dependent RNA synthesis, thereby inhibiting cell growth and replication.
Because of this ability to block genetic activity within cells, actinomycin D is used in cancer treatment to slow or stop the growth of rapidly dividing tumour cells. It is used particularly in certain childhood cancers and other specific malignancies. The drug must be administered carefully due to its potent biological effects and potential side effects.

KembaraXtra - Medical Terms - Actinomyces Actinomyces is a genus of Gram-positive bacteria that resemble fungi in appearance, although they are true bacteria. These organisms are nonmotile and typically grow in branching filamentous forms. They are normally present in the human mouth and other body sites but can sometimes cause disease.
One important species, Actinomyces israelii, is responsible for the infection known as actinomycosis. When these bacteria invade deeper tissues, usually following dental infections or injury, they can produce chronic infections characterized by swelling and abscess formation. Their fungus-like appearance historically led to confusion regarding their classification.

KembaraXtra - Medical Terms - acoustic shock Acoustic shock is a reaction that occurs after exposure to a sudden unexpected loud noise, often referred to as an acoustic incident. It most commonly affects individuals who use headsets or telephones for prolonged periods, such as call centre operators or communication staff. The sudden noise can trigger a reflexive response in the auditory system and surrounding muscles.
Symptoms of acoustic shock may include ear pain, dizziness, ringing in the ears (tinnitus), anxiety, and sometimes emotional distress such as depression. Unlike noise-induced hearing loss, acoustic shock does not usually cause permanent damage to hearing. However, the condition can still significantly affect a person’s comfort and ability to work, making prevention and early management important.

KembaraXtra - Medical Terms - acoustic neuroma Acoustic neuroma is another name for vestibular schwannoma, a benign tumour that develops from Schwann cells covering the vestibular portion of the vestibulocochlear nerve. This tumour usually grows slowly and arises near the inner ear, affecting structures responsible for hearing and balance.
As the tumour enlarges, it may press on nearby nerves and brain structures. Symptoms commonly include hearing loss in one ear, tinnitus (ringing in the ears), dizziness, and problems with balance. In some cases, facial numbness or weakness may also occur if nearby nerves are compressed. Treatment options may include monitoring, surgical removal, or radiation therapy depending on the tumour’s size and symptoms.

KembaraXtra - Medical Terms - acoustic nerve
The acoustic nerve is another name for the cochlear nerve, which is a component of the vestibulocochlear nerve (cranial nerve VIII). This nerve plays a vital role in the auditory system by transmitting sound information from the inner ear to the brain, allowing the brain to interpret and recognize sounds.
The cochlear portion of this nerve carries electrical signals generated by the hair cells within the cochlea, which respond to sound vibrations. Damage or dysfunction of the acoustic nerve can lead to hearing impairment or complete hearing loss. Because of its essential role in hearing, it is an important structure studied in audiology and neurology.
