Calciphylaxis: a rare but potentially fatal event of chronic kidney disease. Case report

Calciphylaxis or calcific uremic arteriolopathy is a rare cutaneous-systemic disease occurring in patients with advanced chronic kidney disease. The classical clinical picture is that of a necrotic and progressive skin ulcer of reticular pattern, mostly in the lower legs and susceptible to local infection. It is a product of mural calcification and occlusion of cutaneous and sub-cutaneous arteries and arterioles. The authors report the case of a 73-year-old male patient in his late stage of renal disease presenting severe necrotic cutaneous ulcers on lower legs followed by local and systemic infection and death due to sepse after parathyroidectomy.

Exames laboratoriais importantes no diagnóstico da Piometra canina

Canine Pyometra is a uterine disease that occurs in sexually mature bitches, with higher incidence in nulliparous and animals over 4 years and is characterized by presenting an accumulation of pus in the uterine lumen, usually occurring in diestrus. Laboratory tests are important tools for the detection of metabolic abnormalities associated with sepsis and renal function, which are serious consequences of pyometra. In blood the main findings are normochromic non-regenerative anemia, presence of dehydration, and sometimes thrombocytopenia. The WBC count may be normal but most often occurs a neutrophilic leukocytosis with a left shift, monocytosis and the presence of toxic neutrophils. In less than 1 / 3 of the animals the presence of azotemia is present and a density lower than 1035 is detected in the urine of almost 90% of bitches which may be in normal range at the onset of the desease. Urinary protein loss is rare but the protein may be elevated in the reagent strip due to urinary contamination by uterine secretion. The increase of gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and creatine kinase (CK) may be present, indicating disorders in the liver. Currently, additional laboratory tests are being studied for the diagnosis of pyometra and its prognosis, such as the measurement of C-reactive protein and fibrinogen for monitoring the recovery of the inflammatory process and the urine electrophoresis to characterize the origin of proteinuria in these animals . The aim of this work is to review the literature on the main laboratory tests that aid the diagnosis of Pyometra

Família Enterobacteriaceae, Acinetobacter baumannii e Pseudomonados na microbiota bucal de pacientes mantidos em unidades de terapia intensiva

Enteric organisms, pseudomonads and other opportunistic microorganisms in the oral microbiota have been linked to serious infections in patients hospitalized in intensive care units (ICU). The present study evaluated the presence of family Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii in the mouth of patients in ICU, correlating it with oral and systemic conditions. Data on health, socioeconomic status, medication use, drug addiction, medical and family histories of patients held for more than 72 hours in the ICU with a diagnosis of severe infection or that developed this condition after entry in said unit were obtained. Fifty patients provided clinical samples of supragingival and subgingival biofilms, saliva and oral mucous membranes were collected, as well as respiratory secretions from patients with pneumonia, blood and urine for sepsis. The presence of target microorganisms was carried out by polymerase chain reaction (PCR) and by culture using selective media. The Chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients were poor. The family Enterobacteriaceae was the most prevalent, affecting 39.5% of the supragingival biofilm samples of patients attended in ICU and 18.6% of patients in the control group, besides the rods were the only group found in extraoral samples.

Changes in tissue perfusion parameters in dogs with severe sepsis/septic shock in response to goal-directed hemodynamic optimization at admission to ICU and the relation to outcome

Objective To evaluate the changes in tissue perfusion parameters in dogs with severe sepsis/septic shock in response to goal-directed hemodynamic optimization in the ICU and their relation to outcome. Design Prospective observational study. Setting ICU of a veterinary university medical center. Animals Thirty dogs with severe sepsis or septic shock caused by pyometra who underwent surgery and were admitted to the ICU. Measurements and Main Results Severe sepsis was defined as the presence of sepsis and sepsis-induced dysfunction of one or more organs. Septic shock was defined as the presence of severe sepsis plus hypotension not reversed with fluid resuscitation. After the presumptive diagnosis of sepsis secondary to pyometra, blood samples were collected and clinical findings were recorded. Volume resuscitation with 0.9% saline solution and antimicrobial therapy were initiated. Following abdominal ultrasonography and confirmation of increased uterine volume, dogs underwent corrective surgery. After surgery, the animals were admitted to the ICU, where resuscitation was guided by the clinical parameters, central venous oxygen saturation (ScvO2), lactate, and base deficit. Between survivors and nonsurvivors it was observed that the ScvO2, lactate, and base deficit on ICU admission were each related independently to death (P = 0.001, P = 0.030, and P < 0.001, respectively). ScvO2 and base deficit were found to be the best discriminators between survivors and nonsurvivors as assessed via receiver operator characteristic curve analysis. Conclusion Our study suggests that ScvO2 and base deficit are useful in predicting the prognosis of dogs with severe sepsis and septic shock; animals with a higher ScvO2 and lower base deficit at admission to the ICU have a lower probability of death.

Dermatomiosite em adulto: experiência de um centro terciário brasileiro

OBJETIVOS: Relatamos os resultados de um estudo de coorte retrospectivo envolvendo 139 pacientes com dermatomiosite, conduzido de 1991 a 2011. MÉTODOS: Todos os pacientes preenchiam pelo menos quatro dos cinco critérios de Bohan and Peter (1975). RESULTADOS: A média de idade dos pacientes no início da doença foi de 41,7 ± 14,1 anos, e a duração da doença foi de 7,2 ± 5,2 anos. A amostragem constitui-se de 90,2% de indivíduos brancos, 79,9% do gênero feminino. Sintomas constitucionais foram detectados em menos da metade dos casos. Envolvimentos cutâneo e articular ocorreram em 95,7% e 41,7% dos pacientes, respectivamente. Em 48,2% dos pacientes foram apresentadas pneumopatia incipiente, opacidades em "vidro fosco" e/ou fibrose pulmonar. Todos os pacientes receberam prednisona (1 mg/kg/dia) e 51,1% receberam também metilprednisolona intravenosa (1 g/dia por três dias). Vários imunossupressores foram usados como poupadores de corticosteroide de acordo com tolerância, efeitos colaterais e/ou refratariedade. Houve recidiva de doença (clínica e/ou laboratorial) em 53,2% dos casos; 76,3% permaneceram em remissão no momento do estudo. A taxa de infecção grave foi de 35,3%, com o predomínio de herpes zoster. Houve 15 (10,8%) casos de câncer, dos quais 12 foram confirmados em um período de um ano após o diagnóstico da doença. Houve ainda 16 óbitos (11,5%) cujas causas principais foram sepse/choque séptico (27,5%), pneumopatia atribuída à doença (31,3%), neoplasias (31,3%) e eventos cardiovasculares (12,5%). CONCLUSÕES: No presente trabalho, os dados clínico-laboratoriais foram semelhantes aos de outros grupos populacionais descritos na literatura, com diferenças mínimas quanto à frequência e às características das manifestações extramusculares.
