Cat-scratch disease (CSD) is a clinical syndrome that usually presents as a self-limiting lymphadenopathy associated with a cat scratch or bite. Commonly affecting children and young adults, it has a worldwide distribution. In temperate climates, higher rates are reported in the autumn and winter, which can be attributed to the seasonal breeding of the domestic cat. The organism responsible was...

There are few epidemiological and clinical studies about the presence of cat scratch disease (CSD) on the island of Crete. The objective of this study was to analyze a large number of patients with suspected CSD to define the frequency of Bartonella infections in Crete. From January 2005 to October 2008, we studied patients with suspected CSD from hospitals in Crete. Sera of the referred patien...

Cat scratch disease (CSD) is the most common zoonosis transmitted by household animals. There is limited data on the epidemiology and clinical presentation of this disease in Colombia. The typical presentation includes subacute or chronic lymph node infection following inoculation of Bartonella henselae bacilli through a cat scratch. Cats have a B. henselae seroprevalence as high as 90%. Here, ...

Cat scratch disease (CSD) is a world-wide, diffuse, non-epidemic infection caused by the Gram-negative bacillus Bartonella henselae. The occurrence of encephalopathy represents an infrequent and atypical complication, whose manifestations include ischemic strokes, transverse myelitis and epileptic seizures. Status epilepticus has been described as the most frequent emergency in CSD encephalopat...

learning objectives: ! List the risk factors for Bartonella infections. ! Explain how and where humans and animals can become infected. ! Explain how to diagnose, treat and prevent cat-scratch disease. ! List recommendations you can provide to pet owners about treatment and prevention. ! List the contraindications when prescribing medications for cat-scratch disease. ! List the risk factors for...

We present the case of a 13-year-old immunosuppressed patient with unrelenting cat scratch disease despite 9 months of antibiotic therapy. The patient was being treated with mycophenolate and prednisone for membranoproliferative glomerulonephritis (type 1) diagnosed 13 months before the onset of cat scratch disease. Cat scratch disease was suspected due to epitrochlear lymphadenitis and an inoc...

Visual receptive fields have been mapped with moving patterns in the cat's retinal ganglion cells. A small, general-purpose computer was used to collect a matrix of 2500 data points covering a 25 degrees -by-25 degrees region of space. The analysis of 40 units reveals the existence of many nonconcentric receptive fields and also the presence of line and edge detectors.

Benign lymphoreticulosis (cat scratch disease, CSD) may have a clinical course that varies from the most common lymphadenitis localized in the site of inoculation, preceded by the typical "primary lesion," to a context of severe systemic involvement. Among these uncommon clinical aspects, there is mammarian granulomatous lymphadenitis which may appear as a mastitis or a solitary intraparenchyma...
