Two types of Klebsiella pneumoniae (KP) strains are currently emerging: hypervirulent (hvKP) strains and carbapenem-resistant (CR-KP) strains. To date, these two strain types rarely overlap. Recent reports, however, suggest that CR-KP strains are increasing in virulence. hvKP strains frequently present as highly invasive infections, such as necrotizing skin and soft tissue infections (NSSTI). To examine whether CR-KP strains with features of hvKP were present in our U.S. hospital, we retrospectively identified four cases of CR-KP NSSTI diagnosed between January 2012 and January 2016...

BACKGROUND: Managing cutaneous substance loss after debridement is challenging, especially if it is secondary to necrotizing soft tissue infection, such as necrotizing fasciitis and Fournier gangrene. After skin graft reconstruction, the healing process is longer and may be difficult, depending on the wound site, skin defect size, and patient comorbidities. OBJECTIVE: The aim of this study was to investigate whether autologous platelet-rich plasma (A-PRP) could accelerate and improve wound healing after cutaneous reconstruction for tissue loss secondary to soft tissue infection...

Necrotizing Fasciitis (NF) is a rare, rapidly progressive severe bacterial soft tissue infection with a high mortality rate. NF classically involves the trunk, groin/perineum, lower limbs, and postoperative wound sites. NF secondary to spinal anaesthesia in a young postpartum female is extremely rare. Here we are describing a young postpartum female who underwent cesarean section for the delivery of child but developed NF of the back starting from the site of spinal needle insertion. She was referred to our center after 21 days of surgery with extensive NF...

RATIONALE: Among the nontuberculous mycobacteria, Mycobacterium abscessus is a common cause of skin, soft tissue, and bone infections. However, disseminated M. abscessus infection that mimics cancer metastasis with an underlying relatively immunocompetent condition has rarely been reported. PATIENT CONCERNS: A nonsmoking 73-year-old man with an underlying relatively immunocompetent condition reported a 2-month history of a mass in the region of his right parotid gland that had been steadily increasing in size...

Sweet syndrome, or acute febrile neutrophilic dermatosis, is a systemic disease process mainly characterized by hyperpyrexia and skin lesions. A newly described entity, necrotizing Sweet syndrome, is a severe and locally aggressive dermatological condition that clinically and histopathologically resembles a necrotizing soft tissue infection. It is characterized by pathergy, a nonspecific inflammatory response to cutaneous trauma resulting in a propagation of the disease. In contrast to a necrotizing infection, this condition responds to systemic steroids...

Cellulitis is a frequent soft tissue and skin infection. The lower limbs are affected in 70 to 80% of cases. Cellulitis in aged persons is not yet well described in literature. A retrospective descriptive study conducted in the Internal Medicine Department of Sahloul hospital in Sousse in Tunisia. It included patients whose age was up to 65 years old admitted into hospital for cellulitis of the legs, the arms or the face. One hundred fifty eight patients with a mean age of 73 years old (range: 65 to 94 years old) were included...

Staphylococcus aureus, although generally identified as a commensal, is also a common cause of human bacterial infections, including of the skin and other soft tissues, bones, bloodstream, and respiratory tract. The history of S. aureus treatment is marked by the development of resistance to each new class of antistaphylococcal antimicrobial drugs, including the penicillins, sulfonamides, tetracyclines, glycopeptides, and others, complicating therapy. S. aureus isolates identified in the 1960s were sometimes resistant to methicillin, a ß-lactam antimicrobial active initially against a majority S...

Strangulation of groin hernia can result in significant morbidity and mortality. Spontaneous external fistulation following strangulation is rare and typically occurs with Richter's hernia. Spreading Necrotizing Soft Tissue Infection (NSTI) secondary to Enterocutaneous Fistula (ECF) is an ominous sign, further worsening its prognosis. Early diagnosis and prompt surgical treatment is crucial to improve outcome. Herewith the authors are presenting a case of neglected inguinal hernia. It was complicated with ECF formation and rapidly spreading NSTI of flank...

Monitoring of perfusion is a cornerstone in surgery, phlebology and basic science to proof wound healing by interventions. In chronic wound management it is of utmost importance to realize and parametrize wound bed perfusion to verify actual, and plan further treatment by noninvasive diagnostics. Up to now monitoring is based on visual inspection of wounds as conventionally practiced over more than decades. The main problems of visual inspection are the lack of standardization and comparability because of interindividual variations...

REVIEW
Frank Hanses
Bacterial skin and soft tissue infections are frequent and represent one of the most important differential diagnoses in patients presenting with reddened and swollen skin and soft tissue. Among these infections, cellulitis (phlegmon), erysipelas and abscesses are the most frequent. Whereas erysipelas is almost exclusively caused by streptococci and can be successfully treated with penicillin, an effective antibiotic therapy targeted at Staphylococcus aureus should be empirically considered for abscesses and phlegmon; other pathogens, such as gram negative and anaerobic bacteria can be found in patients with the corresponding underlying disease and certain risk factors...

BACKGROUND: HIV-infected patients pose a high risk of contracting skin and soft tissue infections caused by Staphylococcus aureus. Those who are colonized with methicillin-resistant S. aureus (MRSA) that carry Panton-Valentine leukocidin (PVL) are predisposed to severe infections that could lead to necrotic skin infections. However the association of S. aureus specifically methicillin sensitive S. aureus carrying PVL gene in HIV patients has not been widely reported. Here, we study the prevalence and the molecular epidemiology of PVL-producing S...

Musculoskeletal trauma and infections are commonly encountered in the emergency department. Magnetic resonance imaging (MRI) is rarely employed in true emergencies and most musculoskeletal studies can be deferred to the outpatient setting. This article seeks to address the urgent conditions in which MRI can play a role in diagnosis, management, and treatment. This article outlines MRI's role in the evaluation of posterolateral corner injuries and other soft-tissue pathologies such as rhabdomyolysis, diabetic myonecrosis, septic arthritis, cellulitis, necrotizing fasciitis, and compartment syndrome...

BACKGROUND: The nitric oxide system could play an important role in the pathophysiology related to necrotizing soft tissue infection (NSTI). Accordingly, we investigated the association between plasma nitrite level at admission and the presence of septic shock in patients with NSTI. We also evaluated the association between nitrite, asymmetric dimethylarginine (ADMA), L-arginine, L-arginine/ADMA-ratio and outcome. METHODS: We analyzed plasma from 141 NSTI patients taken upon hospital admission...

Necrotizing fasciitis (NF) is an infection of the soft tissues pathology with high mortality that spreads through the fascial planes and rarely seen in head and neck region. The cause of infection is often odontogenic problems. Broad-spectrum antibiotics, surgical debridement, and hyperbaric oxygen therapy (HBO) are important for the treatment of disease. We report a case of cervical NF in a 33-year-old woman who was treated with rapid surgical debridement and simultaneous HBO.

BACKGROUND: Naja atra snakebite is uncommon in Taiwan and causes distinct effects on its victims. Although the Taiwan government produces its own specific antivenom, little information on the management of N. atra snakebite is available. MATERIALS AND METHODS: We retrospectively evaluated 183 patients admitted to two medical centers. Of these, 45 were identified as definite cases of N. atra snakebite, 86 as suspected cases, and 52 as clinical cases. Demographic data, symptomatology, and management were compared between these case groups...

BACKGROUND: Staphylococcus aureus strains that are Panton-Valentine leukocidin (PVL) positive cause severe skin and soft tissue infections as well as necrotizing pneumonia. The presence of PVL gene is a marker for methicillin-resistant S. aureus; therefore, survey on prevalence and phylogenetic distribution of PVL is of great importance for public health. The aim of this research was molecular epidemiology survey of S. aureus PVL positive, isolated from two tertiary hospitals of Sanandaj...

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are aggressive infections associated with significant morbidity, including amputation and organ failure, and high mortality. The rapid progression and significant risk of morbidity and mortality associated with NSTIs makes quick diagnosis and treatment critical. The objective of this study was to determine the presentation of patients diagnosed with NSTIs and their in-hospital outcomes. METHODS: This was a retrospective review of adult (>17 years) patients with a discharge diagnosis of necrotizing fasciitis at London Health Sciences Centre (annual census 125,000) over a 5-year period (April 2008-March 2013)...

Jeffrey A Freiberg
The presence of pus is one of the most easily recognizable signs of an infection. However, for several centuries suppuration, known as 'laudable pus,' was believed to be a sign of a healthy, healing wound. This historical misconception can be explained by the difference in the presentation of a necrotizing soft tissue infection versus other more common skin and soft tissue infections. Chronic wound infections, due to pyogenic bacteria, typically produce large amounts of thick, whitish-yellow pus. On the other hand, necrotizing soft tissue infections, despite their severe mortality and morbidity, are devoid of pus in the traditional sense...

BACKGROUND: Necrotizing myositis is a rare but life-threatening soft-tissue infection characterized by rapidly spreading inflammation and subsequent necrosis of the affected tissue. The myositis is often caused by toxin-producing, virulent bacteria such as group A β-hemolytic streptococcus and associated with severe systemic toxicity. It is rapidly fatal unless diagnosed promptly and treated aggressively. However, necrotizing myositis is often initially misdiagnosed as a more benign soft-tissue infection as such fulminant, invasive muscle infections are rare with no more than 30 cases reported over the last century...
