Bacterial Skin Infections Very normal Range from irritating to savage diseases Mostly brought about by Staph aureus and Strep

Slide 5

Bacterial Skin Infections Folliculitis Infection of hair follicle Usually recuperates without scarring Caused by Staph aureus Tx : Warm saline packs. In the event that does not resolve suddenly in 1-2 weeks, topical mupirocin . Oral dicloxacillin ( exceptionally uncommon)

Slide 6

Young male giving pruritic erythematous macules that advanced to papules and pustules. 3 days back he has been to a spin pool. Hot tub folliculitis

Slide 7

Hot tub Folliculits Caused by Pseudomonas aeruginosa , regularly found in defiled waterpools , hot tubs, water slides or physiotherapy pools Rash can eject anyplace on the body that has been in contact with tainted water Most cases resolve all alone, tx : silvadene cream, cipro (for broad cases) Prevention: visit changing of water, continous water filtration, observing of disinfectant levels( chlorination) in pools. Giving after contact does not counteract disease

Slide 8

Furuncle Carbuncle

Slide 9

Staph Skin Infections Furuncle/Boil Infection of pilosebaceous unit(hair follicle and encompassing tissue) Usually should deplete before they recuperate – takes under 2 wks Complicated bubbles – over center of face/spine or fever Carbuncle Several furuncles that are densly stuffed together basic in diabetics Tx : serious cases, first I&D Oral abx ( dicloxacillin or cephalexin ) if fever

Slide 10

Slide 11

Acute Paronychia Infection of horizontal and back nail overlap Most normal pathogen Staph aureus Results from nail gnawing, finger sucking, exorbitant manicuring or infiltrating injury Conservative tx : Warm douses/oral anti-microbials ( clindamycin , augmentin ) If sore or fluctuance is available, unconstrained waste/cut and seepage.

Slide 13

Impetigo ( Bullous frame)

Slide 14

Impetigo Nonbullous (MC shape) – main pathogen is Staph aureus . Assemble A beta hemolytic strep minority of cases. Bullous shape is almost brought on by Staph aureus ( regular in babies and youngsters <2yrs) Honey crusted injuries/huge vesicles Tx : topical mupirocin as powerful as oral abx Oral abx for nonlocalized cases - dicloxacillin , 1 st gen cephalosporin, augmentin . Macrolides not satisfactory given expanding resistance. Confusion: Strep glomerulonephritis Nasal carriage, hotspot for recc , tx w/topical mupirocin x 5 d Very infectious, suitable cleanliness for anticipation

Slide 15

Denoting the erythema edges w/ink is useful in taking after the movement or relapse of cellulitis . I&D if fluctuant May transform into necrotizing fascitis – medicinal crisis

Slide 17

MRSA Infections – on the ascent Community related – MRSA in youngsters in childcare Athletes Military enlisted people Healthcare related –MRSA Resistant to numerous abx , send for C&S Tx : CA-MRSA : Clindamycin , Doxycycline , Bactrim , Vancomycin HA-MRSA : Vanc , Linezolid Recurrence extremely basic Prevention: individual cleanliness is the key Wash hands !! Try not to share individual things Cover every open injury

Slide 18

Coral pink brilliance Erythrasma

Slide 19
