CHAPTER 17 Flashcards
Inflammation of the skin
Dermatitis
Inflammation of a hair follicle, the sac that contains a hair shaft.
Folliculitis
Inflammation of a sebaceous gland that opens into a follicle of an eyelash.
Sty
A localized pyogenic (pus-producing) infection of the skin, usually resulting from folliculitis; also known as a boil.
Furuncle
A deep-seated pyogenic infection of the skin, usually arising from a coalescence of furuncles.
Carbuncle
surface lesion that is neither raised nor depressed, such as the lesions of measles
Macule
A surface lesion that is firm and raised, such as
the lesions of chickenpox
Papule
A blister or small fluid-filled sac, such as is
seen in chickenpox and shingles
Vesicle
A pus-filled surface lesion.
Pustule
three pathways for pathogens to enter the ear
eustachian (auditory) tube ; from throat & nasopharynx
external ear
via the blood or lymph
An infection or inflammation of the cornea the domed covering over the iris and lens.
Keratitis
infection that involves both
the cornea and conjunctiva
Keratoconjunctivitis
which respiratory tract
infections are the most
common cause of
death from infectious
diseases
lower
Inflammation of the mucous membrane lining of the bronchial tubes; most commonly caused
by respiratory viruses
Bronchitis
Inflammation of the epiglottis (the mouth of the windpipe); may cause respiratory obstruction,
Epiglottitis
Inflammation
of the mucous membrane
and underlying tissue commonly referred
to as sore throat
Pharyngitis
Inflammation of one or both lungs. Alveolar sacs become filled with exudate, inflammatory
cells, and fibrin
Pneumonia
causes of pneumonia
bacteria or viruses
fungi
protozoa.
cause of pharyngitis
S. pyogenes
Viruses
cause of epiglottitis
Haemophilus
influenzae type b (Hib).
cause of sinusitis
Streptococcus pneumoniae
H. influenzae
they start when the external surface (the enamel) of a tooth is dissolved by organic acids produced by masses of microorganisms attached to the tooth (dental plaque).
- Dental caries. (tooth decay/ cavities)
the most common
cause of tooth decay, which produces lactic acid as an
end product in the fermentation of glucose
S. mutans.
Oral diseases such as gingivitis, periodontitis,
and trench mouth are collectively known as
periodontal
diseases
microbial activities in the mouth
- formation of dextran (sugar by streptopcocci
- acid production by lactic
acid–producing bacteria - deposition of calculus
- secretion of inflammatory substances
frequent discharge of semisolid or fluid fecal matter. defined as diarrheal specimens as “stool specimens that conform to the shape of the container.”
Diarrhea
Frequent watery stools, accompanied by abdominal pain, fever, and dehydration. The stool specimens may contain blood or mucus.
Dysentery
Inflammation of the intestines, usually referring to the small intestine
Enteritis
Inflammation of the mucosal lining of the
stomach.
Gastritis
