Study Notes

Bronchopneumonia

Inflammation affecting bronchioles and adjacent alveoli
Often spreads throughout the lungs
Patchy inflammation

Interstitial Pneumonia

Inflammation primarily in the interstitial spaces of the lung
Affects alveolar walls
Commonly associated with viral infections or atypical bacteria

Asthma

Chronic inflammatory disease of airways
Triggered by allergens or irritants
Symptoms: wheezing, shortness of breath, chest tightness, coughing

Emphysema

Progressive lung disease
Often caused by smoking
Leads to destruction of alveoli
Symptoms: chronic cough, difficulty breathing, decreased ability to exercise

Histoplasmosis

Fungal infection caused by inhaling spores
Spores from soil or bird droppings
Symptoms: fever, cough, fatigue, chest pain

Tuberculosis (TB)

Bacterial infection
Primarily affects the lungs
Symptoms: persistent cough, weight loss, night sweats, fever

Legionnaire's Disease

Severe form of pneumonia
Caused by Legionella bacteria
Bacteria often found in water systems
Symptoms: cough, shortness of breath, fever, muscle aches

Severe Acute Respiratory Syndrome (SARS)

Viral respiratory illness
Caused by the coronavirus SARS-CoV
Symptoms: fever, chills, cough, difficulty breathing

Anthrax

Bacterial infection
Caused by Bacillus anthracis
Often linked to exposure to infected animals or contaminated products
Symptoms vary by type
Pulmonary anthrax symptoms: fever, sore throat, respiratory distress

Bronchogenic Carcinoma

Type of lung cancer originating in the bronchial tubes
Often linked to smoking and exposure to carcinogens

Cystic Fibrosis (CF)

Genetic disorder affecting lungs and digestive system
Causes thick, sticky mucus production
Leads to respiratory infections and digestive issues

Bronchiectasis

Condition where bronchial tubes are permanently widened and damaged
Leads to mucus buildup, chronic infections, and difficulty clearing airways

Pulmonary Embolus

Blockage in a pulmonary artery
Usually caused by blood clots
Clots travel from legs or other parts of the body (deep vein thrombosis)

Adult Respiratory Distress Syndrome (ARDS)

Severe inflammatory response in the lungs
Leads to impaired gas exchange
Often caused by trauma, pneumonia, or sepsis

Flail Chest

Condition where a segment of the rib cage breaks and becomes detached
Detachment from the rest of the chest wall
Leads to abnormal movement during breathing

Pneumothorax

Presence of air in the pleural space
Causes the lung on that side to collapse
Results in difficulty breathing and chest pain

Pleural Effusion

Accumulation of excess fluid in the pleural space
Can compress the lung
Causes breathing difficulties

Atelectasis

Collapse or incomplete expansion of a lung or part of a lung
Leads to reduced gas exchange
Often due to blockage of airways or pressure from outside the lung

Infant Respiratory Distress Syndrome (IRDS)

Primarily affects premature infants
Characterized by difficulty breathing due to insufficient surfactant in the lungs
Causes: prematurity, surfactant deficiency, maternal diabetes, cesarean delivery
Signs/Symptoms: rapid shallow breathing, grunting sounds during breathing, nasal flaring, retracting of the chest muscles, cyanosis
Age Group: most commonly affects premature infants, especially those born before 34 weeks of gestation

Supratentorial Lesion

Lesion located above the tentorium cerebelli
Typically involves the cerebral hemispheres

Noncommunicating Hydrocephalus

Type of hydrocephalus where the flow of cerebrospinal fluid (CSF) is blocked
Prevents CSF from reaching the ventricles or being absorbed properly
Often caused by obstructions like tumors or congenital malformations

Communicating Hydrocephalus

CSF can flow between ventricles but is not being absorbed adequately into the bloodstream
Factors like infection, bleeding, or other conditions affecting CSF absorption can cause it
Leads to increased intracranial pressure

Spina Bifida

Congenital condition where the spinal column does not close completely around the spinal cord
Leads to potential nerve damage and physical disabilities

Spina Bifida Occulta

Mild form
Spinal column is not fully closed, but there is no protrusion of the spinal cord or nerves
Usually asymptomatic, may present with back pain, hair tufts, or pigmented lesions over the affected area

Meningocele

Protective membranes around the spinal cord protrude through the vertebrae
Forms a sac
May have minor neurological impairment
Sac may be visible, but the spinal cord remains intact

Myelomeningocele

Most severe form
Spinal cord and nerves protrude through the opening in the spine, forming a sac
Significant neurological impairment, paralysis, loss of sensation, bladder and bowel control issues, and hydrocephalus

Common Causes Across Types of Spina Bifida

Genetic predisposition
- Environmental factors (e.g., lack of folic acid during pregnancy)
- Maternal health issues (e.g., diabetes, obesity)

Astigmatism

Refractive error caused by an irregular shape of the cornea or lens
Leads to blurred vision at various distances

Conjunctivitis

Inflammation of the conjunctiva
Often referred to as "pink eye"
Can be caused by infection, allergies, or irritation

Strabismus

Condition where the eyes do not properly align with each other
Leads to issues with depth perception and double vision

Diplopia

Medical term for double vision
A person sees two images of one object

Presbyopia

Age-related difficulty in focusing on close objects
Caused by loss of lens elasticity

Cataracts

Clouding of the lens in the eye,
Can lead to decreased vision

Glaucoma

Group of eye conditions that damage the optic nerve
Often associated with high intraocular pressure
Potentially leading to vision loss

Macular Degeneration

Degenerative condition affecting the macula
Macula is the central part of the retina
Leads to loss of central vision

Myopia

Also known as nearsightedness
Refractive error where distant objects appear blurry while close objects are clear

Hyperopia

Also known as farsightedness
Refractive error where close objects appear blurry while distant objects may be clearer

Otitis Media

Inflammation or infection of the middle ear
Often causing pain and fluid buildup

Otitis Externa

Infection or inflammation of the outer ear canal
Commonly known as "swimmer's ear"

Otosclerosis

Condition characterized by abnormal bone growth in the middle ear
Leads to hearing loss

Meniere's Syndrome

Disorder of the inner ear causing episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear

Diabetes Mellitus Type I

Autoimmune destruction of insulin-producing beta cells in the pancreas
Typically occurs in childhood/adolescence
Treatments: Insulin therapy, lifestyle management, monitoring blood glucose levels
Complications: Diabetic ketoacidosis

Diabetes Mellitus Type II

Insulin resistance and eventual pancreatic beta-cell dysfunction
Often associated with obesity and lifestyle factors
Treatments: Lifestyle changes (diet, exercise), oral hypoglycemics, and possibly insulin
Complications: Hyperglycemic hyperosmolar state, neuropathy, nephropathy, retinopathy, cardiovascular disease

Diabetes Insipidus

Inability to concentrate urine due to a deficiency of antidiuretic hormone (ADH) or resistance to its effects
Leads to excessive urination and thirst

Goiter Conditions

Conditions leading to a goiter (enlarged thyroid) include: Iodine deficiency, Hashimoto's thyroiditis, Graves' disease, thyroid nodules, Certain medications

Graves' Disease

Autoimmune hyperthyroidism characterized by overproduction of thyroid hormones

Cushing's Syndrome

Excess cortisol production, often due to adrenal tumors or prolonged corticosteroid use
Symptoms include obesity, hypertension, and skin changes

Addison's Disease

Adrenal insufficiency leading to low cortisol and aldosterone
Symptoms include fatigue, weight loss, and hyperpigmentation

Anorexia

Eating disorder marked by loss of appetite or severe restriction of food intake

Nausea

Sensation of unease and discomfort in the stomach often preceding vomiting

Vomiting

Forceful expulsion of the contents of the stomach through the mouth

Bulimia

Eating disorder characterized by binge eating followed by purging

Diarrhea

Frequent, loose, watery stools
Can result from infections, dietary changes, or gastrointestinal disorders

Constipation

Infrequent or difficult bowel movements
Often related to diet, dehydration, or sedentary lifestyle

Herpes Simplex Type 1

Viral infection causing cold sores
Signs include painful blisters

Gingivitis

Inflammation of the gums due to plaque buildup
