Wound healing
3

Healing or is tow types :

1-Primary healing ;- in clean simple wound like simple surgical wounds , the scar formation will be minimum.
2-Secondary healing;- large wounds like car accident or bullet injury , it will take longer healing time and will produce large scar
*Inordinate deposition of extracellular matrix, mostly excessive collagen, at the wound site results in a hypertrophic scar.

Granulation tissue

It is part of the healing process of wounds and is consist of newly formed blood vessels (angiogenesis) and recruitment of fibroblast to the sight of injury and collagen fibers deposition that lead to make a mesh , it start from bottom and sides of the wound

ACTINOMYCES

what is Actinomycosis?

Actinomycosis is a slowly progressive rare bacterial chronic infection involving the jaw, thorax, or abdomen.
The disease is caused by a number of anaerobic bacteria termed Actinomyces, and the most common is Actinomyces israelii.
These organisms are branching, filamentous, gram-positive , non acid fast bacilli

31

causes

Actinomyces is from opportunistic normal flora of mouth ,

1-if there was any breakage or injury in the tissue like in accidental conditions or because of dental procedures
2- if there was severe immunity depression and if there was another infection , Actinomyces will act as
opportunistic organism and will cause the disease
يعني اذا كان هناك التهاب معين و نزل بسببه المناعة فان هذا البكتريا راح يستغل الفرصة و يسوي هو هم التهابات
** 70% of the pathology happen in mouth
3- bad oral hygiene like in surgical conditions in mouth where the patient cannot maintain good oral hygiene

32

clinical signs

abcess formation in mandible or maxilla and they usually break through the skin and discharge through one or more openings (sinus formation). And lumpy jaw , and most important thing is presence of yellow granules of sulfur in the culture media of
Actinomyces and tuberculosis are similar in some signs like abscess (sinus) opened to outside in cervicofacial surface

33

Very impotent note

sinus formation is from cardinal signs of T.B

** main difference between the actinomycosis and T.B , is that there is no necrosis in actinomycosis

neck, chest ,arms, shoulders

What is lipoma?

They feel soft and "doughy" to touch and range from the size of a pea to a few centimeters across. They grow very slowly and don't usually cause any other problems.
Occasionally, lipomas can develop deeper inside the body, so you won't be able to see or feel them

_ nasal polyp in histology: is lose connective tissue and inflammatory cells surrounded by psedostratified columner epithelium , but if it happened in the back of the nose will be ciliated epithelium

55

signs and symptoms

if the flu persist more than one month may indicate nasal polyp that present in sinuses and presented like rhinosinusitis
Sometimes presented with facial pain

56

Causes are

1- one of the complications of plastic surgeries is nasal polyp because it will cause destruction of tissue of nose
2- Hay fever which is seasonal may cause nasal polyp
nasal polyp can cause obstruction of the nose so the patient will breath from his mouth , not from the nose and this will cause dry mouth which will lead to dental caries
