Dermatology - Sepsis
Sepsis is a systemic reaction to infection that can lead to the failure of several organs. Patients typically exhibit elevated body temperature or abnormally low body temperature, rapid breathing, and accelerated heart rate. Abnormalities Erythroderma is indicative of staphylococcal or streptococcal toxic shock syndrome. Typically, people who experience this condition are young and in good overall health. Pustules, especially in newborns or individuals with weakened immune systems, indicate a fungal infection, specifically caused by Candida spp. Pustules resulting from disseminated gonococcemia are found on the extremities, usually causing pain and appearing as gray, hemorrhagic, or black. These pustules are most frequently observed in young individuals who are otherwise in good health. Pustules can also occur as a result of local introduction of bacteria, such as in the case of staphylococcal sepsis. Purpura can result from vasculitis and is often noticeable in the small capillaries of the nail fold, particularly in individuals with thrombocytopenia, which is most typically observed in patients undergoing bone marrow transplantation. Immunocompromised individuals frequently experience opportunistic fungal infections, which typically manifest as red raised skin lesions, small red or purple spots, or pus-filled bumps that develop into purple discoloration. Purpura fulminans can also be caused by severe meningococcemia. Cellulitis is a highly concentrated inflammation in a specific area. Blood cultures seldom yield positive results, and the normal cause of infection is bacterial. Necrotizing fasciitis may result in positive blood cultures at a later stage of the disease as a result of the spread of bacteria through the bloodstream. Ecthyma gangrenosum is characterized by the initial formation of a red papule that later develops into a necrotic bulla. This typically occurs in the area between the umbilicus and the knees. The condition is usually caused by the spread of bacteria on the skin, although other organisms have also been observed. Ecthyma gangrenosum is most commonly seen in patients with a weakened immune system, particularly those with low levels of neutrophils. It often occurs in conjunction with an underlying malignancy. The diagnosis is determined through clinical examination. There is a possibility of increased levels of white blood cells, C-reactive protein (CRP), and procalcitonin. The differential diagnosis comprises cutaneous infections, medication hypersensitivity reactions, cutaneous lymphoma, psoriasis, contact dermatitis, trauma, thrombocytopenic purpura, cryoglobulinemia, and stasis dermatitis. If the patient is not already in the Intensive Care Unit (ICU), they should be admitted immediately. Additionally, administer suitable antimicrobial medications within one hour of diagnosis, either based on empirical selection or guided by the results of a culture. Reassess the selection of antimicrobial agents on a daily basis in order to limit toxicity and optimize effectiveness. The administration of activated drotrecogin has demonstrated a reduction in fatality rates in cases of severe sepsis. Administer appropriate measures to maintain organ function.
