A 49-year-old black man with hypertension-induced chronic renal failure requiring hemodialysis and a history of arteriovenous access graft infection was admitted with Staphylococcus aureus sepsis, dyspnea, and peri-incisional erythema over his arteriovenous graft fistula. Results of a transthoracic echo demonstrated aortic sclerosis and concentric left ventricular hypertrophy. Results of a whole-body In-111 white cell (WBC) scan were negative over the arteriovenous graft site; however, an intense abnormal focus of labeled WBCs was evident to the left of the sternum. A subsequent transesophageal echocardiogram showed a mixed cystic-solid calcified mass adjacent the left aortic cusp. Surgery confirmed a perivalvular abscess. As a whole-body imaging modality, the In-111 WBC scintigram indicated the true location of the infectious process responsible for the patient's sepsis. The combination of echocardiography and radiolabeled WBC imaging increases sensitivity for detection of endocarditis/perivalvular abscess. Radiolabeled WBC imaging is more efficacious for monitoring therapy because the echocardiogram often does not change with treatment of endocarditis/perivalvular abscess.

A case of neonatal Pseudomonas putida sepsis presenting as staphylococcal scalded skin syndrome is described. Staphylococcal scalded skin syndrome is a clinical term used for a spectrum of primarily neonatal blistering skin disorders caused by the exfoliative toxins of Staphylococcus aureus. The disease typically begins with general erythema and fever, followed by the formation of large fluid-filled bullae that coalesce and rupture on slightest pressure to leave extensive areas of denuded skin. The 9-day-old male infant described presented with a generalised non-tender, macular, erythematous rash that later developed into large, flaccid, clear fluid-filled bullae to leave extensive erythematous, weeping, and denuded areas covering over 90% of the total body surface. Despite aggressive antibiotic and symptomatic treatment, he died 11 days after admission. While Pseudomonas infections may present with vesico-bullous eruptions, this is believed to be the first case of neonatal Pseudomonas putida sepsis presenting as staphylococcal scalded skin syndrome.

Acute gangrenous dermo-hypodermitis and necrotizing fasciitis are potentially life-threatening infections of skin and soft tissues, which may be difficult to recognize at an early stage. A combination of local signs (erythema, mottling, bullous formation) and of symptoms suggestive of sepsis should prompt early suspicion and therapeutic intervention. Group A streptococci remain the major pathogen involved in necrotizing fasciitis involving extremities, following minor trauma or surgery, and sometimes apparently spontaneously. The most severe form is streptococcal toxic shock syndrome, where production of exotoxins (superantigens) is a major factor contributing to the severity of the syndrome. A number of other pathogens, often combined in mixed aerobic-anaerobic infections may be involved, especially in post-surgical and perineal gangrene. Surgery remains the mainstay of therapy, and should be considered as soon as the clinical suspicion arises. Antibiotic therapy is based on penicillins (penicillin G for streptococcal gangrene, or beta-lactamases penicillins in polymicrobial infections). New therapeutic approaches (clindamycin and immunoglobulins) may be useful in streptococcal toxic shock. The prognosis appears to have improved in recent years with early therapeutic intervention, but remains largely dependent on the severity of the septic response and underlying diseases.

Gout, although relatively rare in joint replacements, can present as an acute or chronic painful knee or hip arthroplasty. Gout and acute infection of a joint replacement can be difficult to differentiate, with the physical examination and laboratory study results frequently being similar. Both conditions can present with a rapid onset of joint pain, swelling, erythema, and constitutional symptoms, including fevers and malaise. Laboratory findings in both conditions often include an elevated leukocyte count, erythrocyte sedimentation rate, and C-reactive protein level. Negatively birefringent, needle-shaped crystals in the synovial fluid confirm the diagnosis of gout. The mistaken diagnosis of septic arthritis in a joint replacement with crystal-induced synovitis can lead to inappropriate open debridement or component removal. The current study includes a review of the literature and presents two cases of gout after total knee arthroplasty. These cases suggest that in situations of suspected sepsis without synovial fluid crystals, operative intervention is indicated with a presumed diagnosis of septic arthritis. The identification of chalky white or yellow deposits in the synovium or bone is highly suggestive of gout. The definitive diagnosis is made by polarized light histologic evaluation of these tissues. If these deposits are present in the absence of a positive preoperative culture, positive Gram stain for bacteria, or component loosening, component retention is indicated.

Infection of penile prostheses, estimated to occur in 3% of cases, represent the major complication of this type of prosthesis. Early sepsis occurs during the first week and presents in the form of frank clinical features (pain, erythema, penile discharge); highly virulent bacteria are isolated, such as Staphylococcus aureus. Late sepsis occurs after an interval of several weeks to several months with less specific clinical features; Staphylococcus epidermidis is isolated in more than 50% of cases. Conventional treatment of these infections consists of antibiotics adapted to the local flora and removal of the prosthesis, sometimes followed by deferred reimplantation. Prosthetic material salvage procedures are now proposed. Patient-related risk factors for infection include diabetes, urinary tract infection and immunodepression, while procedure-related risk factors include the length of hospital stay, poor operative technique, prolonged operating time and iatrogenic urethral injuries. Prevention of sepsis of penile prostheses is based on prevention of these risk factors and prophylactic antibiotics or prolonged antibiotic therapy.

Findings of diminished or absent pulses, pallor on elevation, redness of the foot on lowering of the leg, sluggish refilling of the toe capillaries, and thickened nails or absence of toe hair are consistent with impaired arterial perfusion to the foot. When ischemia is recognized as contributing to pedal ulceration and infection in the diabetic foot, quantitation of its severity may be difficult. Standard clinical evaluation of trophic changes is limited in an infected foot with its accompanying swelling, edema, and erythema. A palpable pedal pulse does not preclude the possibility of the presence of limb-threatening ischemia. Additional non-invasive vascular studies should be undertaken for these patients. Management of the diabetic foot is often a complex clinical problem. However, the principles of care are simple, including correction of systemic factors, such as blood glucose control, cardiovascular risk factor management, and smoking, as well as local factor correction, such as debridement, pressure relief, infection control, and revascularization when indicated. When a patient presents with evidence of infection, adequate drainage and antibiotic therapy are mandatory. The next step should be performed to differentiate the more common neuropathic ulcerations from the truly ischemic ulceration. Symptoms of rest pain or claudication are not often helpful because many of these patients are asymptomatic as a result of the presence of their neuropathy and inactivity. If an infected foot requires debridement or open partial forefoot amputation, observing the wound on a daily base is also important. Once infection is eradicated, there should be prompt signs of healing, including the development of wound granulation within several days. If wounds are not showing signs of prompt healing, arteriography is necessary. Early aggressive drainage, debridement, and local foot amputations combined with liberal use of revascularization results in cumulative limb salvage of 74% at 5 years in high-risk groups. Others report that pedal bypass to the ischemic infected foot is effective and safe as long as infection adequately controlled. These studies strongly suggest that early recognition and aggressive surgical drainage of pedal sepsis followed by surgical revascularization is critical to achieving maximal limb salvage in the high-risk population. Patients who have diabetes present a unique challenge in lower extremity revascularization because of the distal origination of many bypasses, distal distribution of the occlusive disease, and the frequently calcified arterial wall. An aggressive multidisciplinary approach to foot disease associated with diabetes involving the primary care provider, medical specialists, interventional radiology, and podiatric, plastic, and vascular surgeons will provide optimal medical and surgical care. Peripheral vascular disease is highly treatable if intervention is instituted in a timely and collegial fashion.

We describe a rare case of sinonasal T-cell lymphoma in an 11-year-old boy who presented with a right acute orbit characterized by proptosis, eyelid edema and erythema, limitation of eye movements, and excruciating pain on the right side of his face. Orbital computed tomography showed progressive right extraocular muscle enlargement. One biopsy specimen showed extensive tissue necrosis and an infiltrate of atypical cells with pleomorphic nuclei within the walls of blood vessels. Immunohistochemical studies demonstrated that these cells were positive for leucocyte common antigen (CD45), CD3 cytoplasmic, CD45RO, and terminal deoxynucleotidyl transferase and negative for CD20, CD57, CD56, CD99 and Epstein-Barr virus. Chemotherapy for T-cell non-Hodgkin lymphoma was initiated, but the patient's status deteriorated and the child died of respiratory insufficiency, sepsis, and central nervous system infection.

Epidermolytic hyperkeratosis is an unusual type of ichthyosis. This inherited keratinization disorder is characterized clinically by erythema, blistering, and peeling shortly after birth. It may resolve and be replaced with thick scaling. It can lead to life-threatening complications, such as sepsis. Histologically, there is a hyperkeratosis and vacuolar degeneration. Genetically, this is an autosomal dominant disease with complete penetrance; however, 50% are spontaneous mutations. The clinical phenotype is a result of alterations in the gene(s) for keratin 1 and/or 10. We review this disorder and its therapy, which is mainly symptomatic with emollients and retinoids.

A 38-year-old male farm worker with relapsing acute lymphoblastic leukemia spontaneously developed an ulcerating ulcer on his anterior thigh which was surrounded by a non-tender area of erythema. Bacillus cereus was isolated from the ulcer and blood, and the patient received intravenous penicillin and vancomycin for one week. When sensitivity studies were returned he was treated with gatifloxacin orally. After two weeks of combined antimicrobial therapy and negative blood cultures, the patient received combination chemotherapy with vincristine, prednisone, doxorubicin and cyclophosphamide. He was hospitalized a day after completing chemotherapy with neutropenic sepsis due to B. cereus. He received similar antimicrobial therapy as previously, but died three days later. At autopsy, the patient was found to have acute mitral valve endocarditis and bilateral brain abscesses. This was the first case of B. cereus endocarditis reported in a patient with acute lymphoblastic leukemia.

Glucagonoma is a very rare endocrine pancreatic tumor. At diagnosis, most glucagonomas are malignant and often metastatic. Suspicion of glucagonoma is based on characteristic presentations known as "glucagonoma syndrome". Glucagonoma is often found in the pancreatic body and/or tail and is usually large enough to be localized by computed tomography. We report a case of diffuse glucagonoma necrolytic migratory erythema (NME) in a 45-year-old man with mild diabetes mellitus, mild anemia, and weight loss over 1.5 years. Diffused enlarged pancreas was noted on abdominal ultrasonography incidentally during a routine health check-up. The levels of carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal limits. No enlarged lymph node or extrapancreatic tumor mass was found by several imaging studies. Total pancreatectomy was performed, and the pathology revealed glucagon-producing islet cells and intrapancreatic vascular emboli of tumor cells. He died due to internal bleeding and sepsis after surgery. Presentation of diffuse malignant glucagonoma with tumor emboli but no metastasis or NME is unusual.
