31
Q

Temperature in General Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

release of pressure by the hand or coughing

35
Q

Rovsing’s sign in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Crossed tenderness

  • Pressure on left iliac fossa causes pain felt in right iliac fossa (due to displacement of the gas inside the colon to caecum distending it & appendix, exaggerating the pain).

38
Q

Baldwing’s sign in Local Examination in Clinical picture of typical ( classic ) appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Straight leg raising sign

Raising straight the Rt. L.L causes pain due to pressure on the Rt. Iliac fossa.

39
Q

Muscle guarding or rigidity over right iliac fossa denotes

A

Appendicular mass or abscess or perforation is about to occur, or has occurred.

40
Q

Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

(1) Long retrocaecal appendix :
(2) Pelvic appendicitis:
(3) Subhepatic appendicitis :
(4) Postileal appendicitis :

41
Q

Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Tenderness over the right iliac fossa

If the appendix is in relation to ureter

If appendix is in contact with the psoas muscle (Psoas sign)

42
Q

Tenderness over the right iliac fossa in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

may be minimal and elicited on deep palpation.

43
Q

If the appendix is in relation to ureter in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

pain simulating ureteric colic will be misleading.

44
Q

Psoas sign in Long retrocaecal appendix in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A
  • If appendix is in contact with the psoas muscle, psoas spasm may be sufficient to cause flexion of the hip joint.
  • Extension of the hip causes abdominal pain.
45
Q

Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Symptoms related to the rectum or to the bladder

Tenderness

Zachary Cope sign :

46
Q

Symptoms related to the rectum or to the bladder in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

symptoms related to the rectum as tenesmus & diarrhea

symptoms related to the bladder as frequency of micturation

47
Q

Tenderness in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Absence of tenderness over McBurney’s point.

Tenderness can be elicited on P.R. & P.V.

48
Q

Zachary Cope sign in Pelvic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A
  • If the appendix is in relation to the obturator internus muscle, spasm of the muscle causes flexion & external rotation of the hip.
  • So internal rotation of the flexed thigh will cause
    abdominal pain.
49
Q

Subhepatic appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Picture of acute cholecystitis

50
Q

Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A
  • Diarrhea.

* Portal pyaemia.

51
Q

Pathogenesis of Diarrhea in Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Due to irritation ~~ mucus secretion

52
Q

Pathogenesis of Portal pyaemia in Postileal appendicitis in Atypical presentations of acute appendicitis in CLINICAL PICTURE of ACUTE APPENDICITIS

A

Thrombophlebitis of iliocolic vein of the ileocolic vein leading to portal pyaemia.

53
Q

Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS

A

  3. Acute appendicitis in pregnancy
54
Q

Pathogenesis of Acute appendicitis in children in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS

A

* Misdiagnosed as gastroenteritis.

55
Q

Pathogenesis of Rapid perforation in Acute appendicitis in children in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS

Cancer caecum should be suspected Due to obstruction not infiltration

57
Q

Pathogenesis of Gangrene & perforation in Pathogenesis of Acute appendicitis in old age in Acute appendicitis in certain circumstances in CLINICAL PICTURE of ACUTE APPENDICITIS
