Block 1 Flashcards
Explain about the asepsis and the method of asepsis
Asepsis refers to absence of infectious material or infection
Method :
I) Sterilization : technique necessary for the complete destruction or remove, of all microorganism that could contaminate any area , equipment or surface during an invasive procedure and constitute a health hazard.
II) Disinfection : processs of killing all,microorganism except spores on an inanimate object
Ex:
physical agents : sunlights , drying , heat-dry and moist , filtration , radiation
Chemical agents : alcohol , aldehyde , dye , halogens , gases
State the classification of ulcers
Specific ulcers
1) TB ulcer
2) Syphillis
3) Actinomycosis
4) Malignancies
- squamous cell carcinoma
- basal cell carcinoma
- malignant melanoma
- Marjolin’s ulcer
Non specific ulcers
- Infective
- Traumatic
- Trophic
-Tropical
- Diabetic
- Cryopathic
- Bazin’s ulcer
- Martorell ulcer
Describe the types of edges an ulcer might have with an example of each
1) Undermined edge
- subcutaneous tissue destroyed faster than skin
- overhanging skin is thin , friable , reddish-blue and unhealthy
- ex: TB ulcer
2) Punched out edge
- edge of ulcer drops at right angles to the skin surface
- ex: deep trophic ulcer ( DM , arterial ulcer , syphillis )
3) Sloping edge
- ex: healing traumatic ulcers , venous ulcers
4) Raised and pearly white , beaded edge
- ex : BCC
5) Rolled Out / everted edge
-due to fast growing cellular disease , edge of ulcer heaps up and spills over the normal skin
- ex : SCC , ulcerated adenocarcinoma
State the 5 aspects of patient treatment in case of diabetic foot ulcer
1) Strict glycaemic control
- diet ( low GI food )
- OADA , insulin use
2) Wound management
- cleaning and dressing everyday
3) Microbiological management
- antibiotics for infections
4) Vascular management
-sympathectomy to cause perpetual vasodilation — prevent ischemia
- arterial grafts to increase blood supply to ulcer area
5) education ( life-style modifications , awareness )
- exercise , diet , increased 3-6 monthly medical checkups , special footwear
- check feet often , moisturise
- wear shoe with clean dry socks
- stop smoking and alcohol

( Rodent ulcers ) is commonly found on the upper part of face , above a line joining the angle of the mouth to the lobule of the ear
( TB ) ulcers are common in the region of lymphadenopathy — neck , axils and groin
( Diabetic ) ulcers are found at the heel , ball of toes
( Marjolin ) ulcers are found over old scars , burns
( Arterial ) ulcers are usually located in the anterior and outer aspects of the leg ( above lateral malleolus ) , dorsum of foot , toes or the heel
( Syphilitic ) ulcers present on the genitals and groin
Which type of tumor shows positive slipping sign ?
Lipomas
Diabetic foot ulcer arises as a results of ( ……………………………. )
Diabetic foot ulcer arises as a results of ( microvasculopathy , peripheral neuropathy and localised infection)
Atherosclerosis of small arteries of toe leads to peripheral neuropathy —> loss of sensation —> inability to feel pain —> ulceration & infections
Neuropathy also cause loss of sweating —> develops dry skin & cracks —> portal of entry of bacteria , motor function of foot also affected
