Symptomatology and examination of ear
This document provides information on examining patients presenting with ear-related symptoms. It discusses taking a thorough history including details on the chief complaints of hard of hearing, ear discharge, ear ache, tinnitus, and vertigo. Examination of the external ear canal, tympanic membrane, and assessment of hearing loss, speech discrimination, and other auditory functions are described. Causes, characteristics, aggravating/relieving factors of various ear conditions are outlined to help determine the underlying pathology.
Wheeze
Wheeze is a high-pitched whistling sound caused by airflow moving through partially obstructed airways. It is produced when air passes through narrowed portions of the airways at high velocity, causing the airway walls to vibrate and alternately flatten and reopen. This vibration creates a continuous musical sound. Wheeze can be caused by conditions that narrow the airways such as asthma, bronchitis, pneumonia, and foreign body obstruction.

Otitis media with effusion, also known as glue ear, is a condition where fluid builds up behind the eardrum without signs of infection. It is commonly seen in school-aged children and is caused by malfunction of the Eustachian tube which connects the middle ear to the throat. This tube opens to equalize pressure and ventilate the middle ear. When blocked, negative pressure develops in the middle ear leading to fluid accumulation. Glue ear may cause hearing loss, speech delays, and ear fullness or plugging but earaches are usually mild or absent. Diagnosis involves examining the eardrum for opacification or fluid levels behind it using pneumatic otoscopy. Treatment options include medical
Hoarseness
Hoarseness lasting more than two weeks requires an otolaryngologic examination to evaluate for potential chronic laryngitis, benign vocal fold lesions, polyps, nodules, malignancy or neurological issues. The mediastinum is divided into the anterior, middle and posterior compartments, with the anterior containing thymic tumors, cysts and lymphomas, the middle containing thyroid tumors and lymphomas, and the posterior mostly containing neurogenic tumors and esophageal lesions.
STRIDOR
Stridor is a noisy, high-pitched breathing sound caused by upper airway obstruction. It is common in infants due to their small larynx size and loose tissues. The relationship of stridor to inspiration and expiration can provide clues to its cause. Acute stridor is usually due to inflammation and edema causing supraglottic or subglottic obstruction. Common causes include croup, epiglottitis, and infections. Chronic stridor may be due to congenital abnormalities, neurogenic issues, or tumors. Evaluation involves history, examination, and endoscopy. Management depends on the specific cause but may include antibiotics, steroids, intubation, or surgery.

25 Important Cases In Ear Nose Throat | SurgicoMed.com
Case 1: A 10 year old child was having a right mucopurulent otorrhea for the last 4 years. A
week ago he became dizzy with a whirling sensation, nausea, vomiting and nystagmus to the
opposite side; his deafness became complete and his temperature was normal. Three days later
he became feverish, irritable and continuously crying apparently from severe headache. Also he
had some neck retraction. The child was not managed properly and died by the end of the week.
Special senses
The ear is divided into three parts - the outer, middle, and inner ear. The outer ear collects sound waves and funnels them through the ear canal to the middle ear, which contains three small bones that vibrate the inner ear. The inner ear contains the cochlea, which has tiny hair cells that change the vibrations into electrical signals sent to the brain. Ear tubes are small tubes inserted into the eardrum to drain fluid and prevent infections by allowing air into the middle ear. The document also defines several eye and ear-related medical terms.

This document discusses acute suppurative otitis media (ASOM), beginning with the stages of the condition:
1) Hyperaemia stage characterized by hyperemia and a "cartwheel" appearance of blood vessels on the tympanic membrane.
2) Exudation stage with high fever, severe earache, deafness, and bulging of the tympanic membrane due to pus buildup.
3) Suppuration stage where ear discharge becomes purulent and mastoid tenderness decreases.
Treatment involves systemic antibiotics, nasal decongestants, analgesics, and ear cleaning. A myringotomy may be performed to drain pus if the tympanic membrane is

Vaccinations pp
Vaccinations induce active acquired immunity by exposing the body to a modified version of a pathogen to stimulate an immune response without causing disease. A vaccine contains an antigen, either a live weakened pathogen, killed pathogen, or protein version, that is recognized by the body as foreign and stimulates antibody production. Antibodies are proteins that bind to antigens to neutralize or mark them for destruction by white blood cells, conferring future immunity against the pathogen.
Development and birth
Pregnancy normally takes 40 weeks, during which time the embryo develops into a fetus and all organs develop and begin functioning. The uterus, where the baby grows, increases in size and ascends in the abdomen during pregnancy. Delivery involves three stages: the dilation stage where the cervix softens and dilates; the expulsion or pushing stage when the mother is fully dilated; and the placental stage where the placenta is delivered after birth to separate from the uterus.

The uterus, where the baby grows, increases in size and ascends into the abdomen. Delivery involves three stages: dilation of the cervix, expulsion or pushing of the baby, and delivery of the placenta after birth to ensure the mother's health.
Diabetes insipidus
Diabetes insipidus is a disorder caused by inadequate secretion of antidiuretic hormone (ADH) from the pituitary gland. It is characterized by excessive thirst and urination. ADH tells the kidneys to reabsorb water instead of excreting it, but in diabetes insipidus the kidneys do not respond to ADH properly. There are three main types - central diabetes insipidus caused by pituitary or hypothalamus damage; nephrogenic diabetes insipidus from kidney defects; and gestational diabetes insipidus during pregnancy. Treatment depends on the type but may include synthetic ADH, managing water intake, or diuretics.
Placental development
The placenta develops from small projections called chorionic villi on the blastocyst that proliferate and erode into the walls of maternal blood vessels by the 17th day of gestation. By 10 weeks of gestation, the placenta has fully developed and each villus and its branches form cotyledons that allow for respiratory, nutritive, excretory, and endocrine functions by mechanisms like diffusion, active transport, and phagocytosis. The mature placenta is a discoid structure weighing around 500g that is the site of gas, nutrient, waste, and antibody exchange between mother and fetus.
Placenta development
The document summarizes the development and anatomy of the human placenta. It begins by defining the placenta and outlining its objectives. It then describes the development of the placenta from the chorion and decidua, the structures of the mature placenta including the chorionic plate, basal plate, intervillous space and villi, and the maternal and fetal circulations that occur through it. Finally, it discusses placental aging and the degenerative changes that occur over the course of a pregnancy.

Presentation #13
Pressure equalizing tubes (PE tubes) are small tubes placed in the eardrum to treat frequent ear infections, hearing loss due to ear infections, or poor response to antibiotic treatment for ear infections, which commonly occurs in children. An EENT (eyes, ears, nose, throat) physician specializes in treating diseases of the eyes, ears, nose and throat. Bone conduction is the process of sound waves vibrating the bones of the skull within the inner ear.

PE tubes are small tubes surgically placed in the ear drum to drain fluid and relieve pressure, commonly used to treat chronic ear infections in children. Otolaryngologists are ear, nose, and throat specialists who undergo extensive medical training and may specialize in specific areas like ENT surgery. Bone conduction tests like Rinne and Weber use tuning forks to help diagnose conductive versus sensorineural hearing loss.

The document summarizes key information about the eye and ear. It discusses that the eye contains sensory receptor cells for vision and transmits images to the brain via the optic nerve. The study of the eye is called ophthalmology. Abbreviations like EENT, EM, OS, and VA are related to the eye. The ear contains sensory receptors for hearing and equilibrium and transmits information to the brain via cranial nerve VIII. The study of the ear is called otology and hearing disorders audiology. Abbreviations like EENT, AU, BC, OM, and PE tube are related to the ear. A PE tube is used to equalize pressure behind the eardrum and drain fluid from the middle ear.
Chapter 13
A pressure equalizing tube (PE tube) is a small tube surgically placed in a child's eardrum to drain fluid and equalize pressure in the middle ear cavity. PE tubes are placed in children who experience frequent ear infections. The tubes may fall out on their own or remain in the ear. Otitis media is a middle ear infection commonly seen in children where fluid accumulates in the middle ear cavity. The six extraocular muscles control eye movement through the superior rectus, inferior rectus, lateral rectus, medial rectus, superior oblique, and inferior oblique muscles.

A PET tube is a small tube surgically placed in a child's eardrum to drain fluid and equalize pressure between the middle ear and atmosphere. The eye, ear, nose and throat refer to the organs of sight, hearing/equilibrium, smell, and passage to the stomach/lungs respectively. Bone conduction is the transmission of sound to the inner ear through skull bones, explaining why one's recorded voice sounds different. Otitis media refers to middle ear infections often preceded by upper respiratory infections spreading via the Eustachian tube. Emmetropia describes proper eye refractive correlation to axial length bringing light parallel to the optic nerve into focus on the retina. Exotropia is an outward turning eye occurring during
Chapter 13_ Abbreviations
This document defines common medical abbreviations pertaining to the ear and eye. It explains abbreviations such as PE tube, which is a pressure equalizing tube inserted in the ear drum; EENT, which refers to the ear, eye, nose and throat; BC, which stands for bone conduction; AU, which translates to "both ears" in Latin; OM, which is an infection of the middle ear; EM, which means normal vision; XT, which is exotropia or eyes deviated outward; OS, which translates to "left eye" in Latin; EOM, which refers to extraocular movement of the eye muscles; and VA, which is visual acuity or clarity of vision.
K jackson medical terminology chapter 13
PE tube placement is a common ear surgery where a small plastic or metal tube is placed in the eardrum to equalize pressure and drain fluid from the middle ear. PE tubes have been shown to decrease ear infections while not affecting hearing. The tubes usually fall out on their own within 6-12 months. If infections return after the tubes fall out, replacement may be considered.
