Type of infection that is characterized by 'severe local inflammation & pus formation'.
(Pus=accumulation of dead phagocytes (neutrophils) & Tissue debris)
What 2 species are 'highly toxigenic' regarding Pyogenic Infections?
This is a 'localized pyoderma' on hair follicle and confined to the Epidermis most commonly caused by Staph Aureus
(RARELY requires systemic Abx, just better hygiene)
Localized pyoderma that is essentially a 'Deep Folliculitis' that extends in Dermis. Most commonly Staph Aureus.
(RARELY requires systemic Abx, I&D if larger than 5cm)
Localized Pyoderma that is an 'accumulation of Furuncles (boils)'.
(more likely to require systemic Abx, ALWAYS requires I&D)
This superficial pyoderma has discrete borders, is commonly seen in Children, and has 'thick, honey-colored crust'
(Causes=Staph Aureus OR Streptococcus Pyogenes)
What 'Topical Treatments' are used for Impetigo?
(1. Protein synthesis inhibitor to 'de-colonize' patients, 2. Protein Synthesis inhibitor for Oral & Topical use)
This is a 'superficial form of Cellulitis', most common on the Face & Legs, Spreads in hours (rapidly), with well demarcated and raised borders.
Due to a 'zoonotic disease spread by contact with FISH, pigs, and fowl (common in farmers). Similar to Eryisepala due to raised, clearly demarcated border.
(Cause by Erysipelothrix rhusiopathiae, Gram (+) non-spore forming Rod)
A 'deeper & poorly demarcated and flat bordered version of Erysipelas', feels hot & tender, may spread Rapidly.
(More likely S.pyogenes than S. aureus)
This infection 'occurs @ depp Subcutaneous tissue & spreads along Fascial planes', pain out of proportion to appearance, more common to Strep Pyogenes.
(Surgical emergency)
An infection that has spread to the Muscle that is more commonly associated with C.perfrinigens, but S. aureus & S. pyrogenes may cause.
(Gaseous gangrene, requires surgical intervention)
Staphylococcal Scalded Skin Syndrome (Ritter's Dz) involves burned blistered-like lesions. Where must you culture for S.aureus?
(NOT able to culture lesions)
This is a 'localized form' of Staphylococcal Scalded Skin Syndrome that CAN culture S.aureus from lesions.
Toxic Shock Syndrome is caused by TSST in S.aureus and may cause what if not controlled?
(Fever, 'strawberry tongue', sunburn-like rash with petechiae, desquamation of hands & feet)
What is the most common cause of infection caused Osteomyelitis?
(cause Brodie's abscess in bone)
This form of Osteomyelitis is most common in Children & involves Circulatory Architecture.
This form of Osteomyelitis is most common in Adults, in Spine & Long bones.
What is an example of Osteomyelitis secondary to vascular insufficiency?
Which stage of Osteomyelitis is 1. Early with medical management possible, and which stage is 2. Late with presence of Dead bone & Poor vascularization (needing Sx debridement)
Septic arthritis (inflammation of joints due to infection) is most commonly caused by Staph Aureus, but can also be caused by __________ in 'sexually active persons'.
At what point of infection should Systemic Antibiotics be used?
(Epidermis-Dermis-Fascia-Muscle-Bone & Joint)
