Caput medusae

Portal hypertension

Rovsing’s sign.
It’s a clinical sign of appendicitis. It is positive when the patient feels pain in the right lower abdomen after the examiner presses and releases the left lower abdomen. This is because the pressure causes the inflamed appendix to move and irritate the peritoneum, the lining of the abdominal cavity.

Furuncles (boils) are skin abscesses caused by staphylococcal infection, which involve a hair follicle and surrounding tissue. Carbuncles are clusters of furuncles connected subcutaneously, causing deeper suppuration and scarring. They are smaller and more superficial than subcutaneous abscesses. Diagnosis is by appearance. Treatment is warm compresses and often oral antistaphylococcal antibiotics.

Suspect a furuncle if a nodule or pustule involves a hair follicle and discharges necrotic tissue and sanguineous pus, particularly if on the neck, breasts, face, or buttocks.

Culture furuncles and carbuncles.

Drain lesions.

Prescribe antibiotics effective against methicillin-resistant Staphylococcus aureus (MRSA) for patients who are immunocompromised, febrile, or at risk of endocarditis; for lesions < 5 mm that do not resolve with drainage; and for lesions that are > 5 mm, multiple, or expanding.
