Skin and soft tissue infections (ISTIs) are clinical units with varying presentation, etiology, and severity that involve microbial invasion of the skin layers and underlying soft tissues. ISTS range from mild infections such as pyoderma to serious, life-threatening infections such as necrotizing fasciitis. The minimum diagnostic criteria are erythema, edema, heat and pain or sensitivity. The affected area may also become dysfunctional (e.g., hands and legs), depending on the severity of the infection. A patient`s comorbidities (e.g., diabetes mellitus and AIDS) can easily turn a normally mild infection into a rapidly progressing life-threatening (1). ITIs present clinically diverse challenges that require management strategies that effectively identify cases that require immediate attention and intervention, whether medical or surgical, of these less severe cases. Your doctor will determine if you have a skin infection by asking for symptoms and performing a physical exam. Due to its delicate and complicated anatomy and physiology, the skin is very sensitive to irritation, abrasions or trauma, as well as to the development of lesions produced by its own structures (for example, folliculitis). Erythematous skin lesions do not always represent infections.
There is a wide range of differential diagnoses that can occur similar to impetigo, erysipelas or even cellulite. Falagas and Vergidis (26) discussed various common and rare diseases that can mimic HES (Table 3). Skin infection caused by streptococcal or staphylococcal infection. Symptoms include blisters or pustules filled with pus. Blisters can vary in size from peas to large rings. There is often a honey-colored liquid that seeps in and a yellowish crust. Impetigo tends to appear on the face, arms or legs. It is more common in children. It is very contagious. But the symptoms often do not affect the whole body. Some bacteria penetrate normal skin, skin broken by eczema/dermatitis or sores (cause wound infection).
Bacteria, such as viruses, can also sometimes lead to exanthema (rashes). In the case of isti below size, special attention should be paid to the change in flora. As already described, in addition to the typical Gram-positive species, one should also consider enteric-coated species – the so-called « fecal veneer ». Risk factors for increased gram-negative or anaerobic colonization include bedridden patients, severe and chronic infections that require multiple treatments, and extensive necrosis. Treatment recommendations are presented in Table 5 (1-3,36,37). Chronic diabetic peptic infections, especially with extensive necrosis, warrant anaerobic coverage. When it comes to beta-lactam or fluoroquinolones, there is evidence that these two agents have similar efficacy in empirical therapy (38). Given the increasing side effect profile of fluoroquinolones, beta-lactams should be the preferred empirical agents in immunocompetent patients. Skin and soft tissue infections (TPDs) are caused by microbial invasion of the skin and underlying soft tissues. Their presentation, etiology and severity vary. The challenge for urinary tract infections is to effectively distinguish between cases that require immediate treatment and warrant medical or surgical intervention and those that are less severe. Between 7% and 10% of hospitalized patients suffer from UN IPTM, and they are very often seen in emergency care.
The skin is endowed with a very diverse ecology of organisms that can cause infections. The clinical manifestations of IPTM are the culmination of a two-stage process involving the invasion and interaction of bacteria with host disease. Cardinal signs of IPTM are the features of the inflammatory response, accompanied by other manifestations such as fever, rapid progression of lesions and blisters. Diagnosing IPTM is difficult because these infections often mimic other clinical syndromes. To improve the management of iNTD, it is beneficial to develop a gravity stratification approach to determine the appropriate nursing home and empirical treatment.
