Cat Scratch Disease in kidney transplant receptors: is it a rare or underdiagnosed pathology?

Cat Scratch Disease (CSD) is an infectious disorder which appears after cat scratching particularly in children and adolescents. Bartonella henselae is the etiologic agent more frequently involved. There are only a few recent reports demonstrating the disease after transplantation, although the illness is not infrequent in immunologically competent people. Indeed CSD in transplant receptors has only been recently emphasized in the literature and it was concluded that fever and lymphadenopathy in patients who had been exposed to cats should prompt clinicians to maintain a suspicion for the infection. In this report CSD infecting a renal transplanted adolescent complaining of headache, blurred vision and fever, presenting a cat scratching lesion in the right arm, with a bilateral painful cervical lymphadenopathy was related. He also presented indirect immunofluorescency identifying that the two subtype's titles of Bartonella--henselae and quintana--were elevated. Treatment with doxicicline e rifampicin was introduced and the patient became asymptomatic in about 3 weeks.

In this report CSD infecting a renal transplanted adolescent complaining of headache, blurred vision and fever, presenting a cat scratching lesion in the right arm, with a bilateral painful cervical lymphadenopathy was related.

Treatment with doxicicline e rifampicin was introduced and the patient became asymptomatic in about 3 weeks.

A Doença da Arranhadura do Gato (DAG) é uma desordem infecciosa que surge após a arranhadela do animal, especialmente em crianças e adolescentes. Bartonella hanselae é o agente etiológico mais frequentemente envolvido. Há somente poucos relatos recentes demonstrando a doença após transplante renal, embora a mesma não seja infrequente em pessoas imunologicamente competentes. Na verdade, DAG em receptores de transplantes tem sido somente recentemente enfatizada na literatura e concluiu-se que a presença de febre e linfadenopatias em pacientes que estiveram expostos a contato com o animal deveriam sinalizar os clínicos a manter suspeita da infecção. Neste relato de DAG, é exposto o caso de um adolescente transplantado de rim queixando-se de cefaleia, visão borrosa e febre, apresentando cicatriz de arranhadura no braço direito, com linfadenopatia cervical bilateral dolorosa. Também apresentava imunoflorescência indireta identificando que os dois subtipos de Bartonella- a henselae e a quintana- estavam elevadas. Tratamento com doxiciclina e rifampicina foi iniciado e o paciente tornou-se assintomático em cerca de três semanas.

Entendendo os distúrbios hidroeletrolíticos e o equilíbrio ácido-básico / Understanding hydroeletrolytic disturbances and acid-basic balance

Os distúrbios hidroeletrolíticos e o equilíbrio ácido-básico são frequentes no dia a dia de especialidades clínicas e cirúrgicas. O entendimento da sua fisiopatologia é essencial para o seu tratamento adequado. Este artigo discursa sobre os distúrbios hidroeletrolíticos e os do equilíbrio ácido-básico mais comuns.

Electrolyte disorders and acid-base balance occur on a daily basis in both clinical and surgical specialties. The pathophysiological understanding of these disorders is essential for their appropriate treatment. This article addresses the most common electrolyte and acid-base disorders.

Cardiovascular risk factors and carotid intima-media thickness in asymptomatic children.

Atherosclerosis, beginning in childhood, is dependent on several risk factors and may be predictive of coronary artery disease in adulthood. The risk factors for subclinical atherosclerosis are similar to those for clinical disease. Carotid intima-media thickness is a measure of subclinical atherosclerosis and a predictor of subsequent vascular events. This study aimed to examine the relationships of carotid intima-media thickness with known risk factors in asymptomatic children. Family history of cardiovascular disease was collected, together with anthropometric, demographic, and clinical data. Body mass index z-scores were calculated. Serum glucose, lipid fractions, fibrinogen, and C-reactive protein were determined. High-resolution ultrasonography was used to assess intima-media thickness. Associations and relationships of risk factors with composite intima-media thickness were explored. The study enrolled 93 children (44 girls) ranging in age from 49 to 169 months. The boys had a thicker intima-media (0.46 +/- 0.06 mm) than the girls (0.43 +/- 0.06 mm; p = 0.028). The unadjusted triglyceride levels were significantly higher in the overweight and obese children (p = 0.010). Body mass index and overweight/obesity were positively related to intima-media thickness (r = 0.259; p = 0.012 and r (s) = 0.230; p = 0.027, respectively), whereas family history of cardiovascular disease was unrelated. Only gender and overweight/obesity were related to intima-media thickness in a multiple linear regression model (R (2) = 0.125; p = 0.002). Male gender and overweight/obesity were associated with increased intima-media thickness, whereas family history of cardiovascular disease was unrelated.
