BACKGROUND Uremic pruritus is one of the most common disabling problems in patients with chronic renal failure. Few studies have evaluated itching and cutaneous manifestations in hemodialysis-dependent patients. OBJECTIVES The aim of this prospective study was to identify the prevalence of pruritus and cutaneous changes affecting patients undergoing(More)
Chronic myelomonocytic leukemia (CMML) is a clonal disorder of hematopoetic stem cells with myelodysplastic and myeloproliferative features. Skin infiltration by leukemic cells is rare in CMML. A case is presented with severe dermatological involvement and concomitant testicular infiltration. An unusual feature was the evidence that the skin was the primary(More)
Cat scratch disease (CSD) is typically a self-limited regional lymphadenopathy in children and young adults that is caused by Bartonella henselae. The majority of CSD cases resolve spontaneously; however, many systemic complications have been described. We report an unusual case of CSD presenting as an epitrochlear arm mass and complicated by(More)
BACKGROUND Absence of a pathognomonic clinical picture and variable histologic findings often delay diagnosis of nontuberculous mycobacteria (NTM)-induced cutaneous infections, and antimicrobial therapy varies. OBJECTIVE We sought to investigate the clinical, microbiologic, and pathological findings of cutaneous NTM infections and response to different(More)
BACKGROUND Few controlled studies have compared nail disorders in patients with chronic renal failure (CRF) and haemodialysis (HD)-dependent individuals with a healthy population. OBJECTIVE The aim of this study was to compare the prevalence of nail disorders in patients with CRF and patients undergoing HD treatment with a healthy population, and evaluate(More)
BACKGROUND Necrotic arachnidism represents a common health problem and standard treatments are usually safe and effective. OBJECTIVE The aim of this study was to review documented Loxosceles species spider envenomations and identify the natural history of affected patients. METHODS A retrospective single-centre study included 52 patients with necrotic(More)
BACKGROUND Understanding what determines the prognosis of community-acquired pneumonia (CAP) is especially important for decisions on hospitalization and antimicrobial therapy. The objective of the present study was to compare the predictability of mortality in our patients to that of the pneumonia patient outcomes research team (PORT) study. PATIENTS AND(More)

There has been proposed a new approach to a neurocontrol synthesis under conditions of uncertainty. It does not directly use an optimization procedure. In terms of a synthesis technique, the proposed solution is close to inverse neurocontrol, but regarding its functions, the system has properties of a fast predictive control. There have been presented the(More)
