السلام عليكم ورحمه الله وبركاته
كلكم شفتوا منشورات #شرح_روبنز
وكذلك شرح الباثو عملي سنة اولى ايوه سنة الله لا رده من سنة اوووف ...

لذلك ما دام سنة اتعبتكم وجعجتكم كثير💔 ...!
قررنا أعضاء اللجنة العلمية #قسم_الباثو
تنزيل شرح لروبن في منشورات وبعدين يتم الجمع في ملف واحد!😁👌🏼

#اللجنة_العلمية_للدفعة_الخامسة
#شرح_روبنز

1- Focus on this patient and answer the following:

A) Diagnosis: sinus

B)Causes: due to rupture of the periosteum wich leads to a soft tissue abscess ➱ channel to the skin ➱ creating a draining sinus.

C) More common in: in children

1)Diagnosis: acute osteomyelitis.

2)Causes: caused by bacteria and rarely by fungi.

3)Common features: there are ➱1)Dead bone tissue (sequestrum), which contain dead lacunae ( without osteocyte)
2) Inflammatory cells
3) ⇩fibrosis

4)Identify each arrow:
*Yellow🟡➱ colonies of gram positive bacteria.
*Green🟢➱ clusters of neutrophils admixed with fibrin.
*Blue🔵➱ trabeculae of dead bone

5)Complications:
1-Toxemia and septicemia.
2- Septic thrombophlebitis.
3- Direct spread to muscles (common) and joint
(rare).
4-chronic osteomylitis.
5- malignancy in sinus

6)Treatment:
Acute osteomyelitis must be treated surgically to drain pus and prevent bone necrosis. Antibiotics suitable to the patient's age and the organism are given to control hematogenous spread and to treat the local infection. In other words, antibiotics save life, and surgery helps save bone.

1) Diagnosis: acute osteomyelitis

2)Type of cells in this in flammation: inflammatory cells.

1) Diagnosis: acute osteomyelitis

2) Type of cells in this slide: neutrophils

1) Diagnosis: acute osteomyelitis

2)Identify each arrow:
Yellow🟡➱ bone tissue
Blue🔵➱ haemorrhage

1) Diagnosis: chronic osteomyelitis

2) Common features: 1) granuloma (aggregation of lymphocytes)
2) Active new bone formation(involucrum)
3)⇧ fibrosis

3) Identify each arrow:
*Yellow🟡➱ fibrosis
*Red🔴➱ granuloma( lymphocytes)
*Blue🔵➱ active lacunae

4)Complications: 1) pathologic fracture.
2) secondary amyloidosis.
3)endocarditis.
4) sepsis.
5) development of squamous cell carcinoma in the draining sinus tract and sarcoma in the infected bone.

5) Treatment: the combination of antibiotics and surgical drainage.

1) Diagnosis: chronic osteomyelitis

2)Identify the yellow area: gaint cell ( granuloma)

1) Diagnosis: mycobacterial( tuberculous) osteomyelitis.

2)Causes: mycobacterium
1%_3% of individuals with pulmonary or extrapulmonary tuberculosis exhibit osseous infection.

3)Identify the yellow area and the arrows:
*Yellow area🟡➱ caseous necrosis
*Blue arrows🔵➱ gaint cells

4) Treatment: surgically and with antibiotics.
