[Chronic inflammatory bowel diseases in cats].

The aetiology of chronic idiopathic intestinal inflammation is unknown. It is characterized by a diffuse infiltration with inflammatory cells into the intestinal mucosa and sometimes submucosa. Cats with chronic intermittent vomiting and diarrhoea, later on accompanied by anorexia and weight loss, are presented. Definitive diagnosis can be obtained by intestinal biopsy only. An immune pathogenesis is suspected, which is supported by the fact, that chronic inflammatory bowel disease responds to steroid therapy.

[Benign inoculation lymphoreticulosis or cat-scratch disease].

Discovered in 1950-51 by two great parisian medical teams, inoculation lymphoreticulosis, also called cat's scratch disease, is locoregional adenitis whose aetiology is imperfectly determined. Following, often bu not always, cat's scratch, it may evolve to suppuration. Pus is always aseptic. Attributed to Bedsonia's family micro-organism, no cultivation was possible up to date. Evolution is as a rule favourable, but disease is poorly accessible to tetracycline family's antibiotics. Diagnosis is possible by intradermoreaction. The antigen used is tyndallised pus of homologous infection. The role of the cat, still healthy, has not yet been explained.

Cat-scratch disease skin test. Studies of specificity and histopathologic features.

Microscopical examination of biopsy specimens from cat-scratch skin test sites, performed in patients with cat-scratch disease (CSD), sarcoidosis, tuberculosis, and other granulomatous diseases, showed noncaseating granulomatous dermal inflammation in 11 of 12 patients with CSD and in some patients with sarcoidosis or tuberculosis. Biopsy of cat-scratch skin test sites may be a useful ancillary procedure in diagnosing CSD if other granulomatous diseases are excluded.

Cat-scratch disease. Subtle vertebral bone marrow abnormalities demonstrated by MR imaging and radionuclide bone scan.

Cat-scratch disease (CSD) is a benign, self-limited cause of lymphadenitis occurring mainly in children and young adults. Its etiology is a delicate, small gram-negative pleomorphic bacillus. Less common manifestations of CSD are seen in 5% of patients and include Parinaud's oculoglandular syndrome (with enlargement of the preauricular nodes), parotid gland enlargement, encephalitis, radiculopathy, pneumonitis, erythema nodosum, thrombocytopenia, and lytic bone lesions. We describe a patient in whom magnetic resonance imaging initially detected subtle vertebral bone marrow abnormalities that correlated with the site of abnormality on a subsequent radionuclide bone scan.

Serological study of Bartonella henselae in cat scratch disease in Japan.

It has become clear that Bartonella henselae is a common cause of cat scratch disease (CSD). The indirect fluorescence antibody (IFA) test for detection of IgG and IgM antibodies to B. henselae concerning CSD showed that 5 (50%) of 10 patients with CSD had a serum IgG antibody titer of 1:128 or more and that 2 (20%) patients had a serum IgM antibody titer of 1:20 or more. One of 7 asymptomatic members of patients' families (14%) had IgG antibody to B. henselae at a titer of 1:256. IgM antibody to B. henselae was not detected in sera from the patients' families. Both IgG and IgM antibodies to B. henselae were not detected in sera from the healthy control group. These data suggest that B. henselae may be a cause of CSD in Japan.

Epithelioid angiomatosis or cat scratch disease with splenic and hepatic abnormalities in AIDS: case report and review of the literature.

Cat scratch disease (CSD) in the setting of HIV infection is associated with lesions of epithelioid angiomatosis but not with granulomatous lesions seen in the normal host. We report a case of CSD in a patient with AIDS and Kaposi's sarcoma with epithelioid angioma of skin, thrombocytopenia, and abnormalities of liver, spleen, lymph node, and pleura that responded to antimicrobial therapy. We also review reported cases of epithelioid angiomatosis in HIV infections. 12 of these resolved, including 3 without antimicrobial therapy; 18 demonstrated pleomorphic organisms with Warthin-Starry silver stain. Six involved visceral or bony as well as skin lesions. CSD should be considered in the setting of HIV infection with skin nodules even in the presence of biopsy-proven Kaposi's sarcoma. CSD may in these patients be responsible for a variety of disseminated lesions which respond to antimicrobial therapy.

Fine-needle aspirate cytology suggesting hepatic lipidosis in four cats with infiltrative hepatic disease.

Four cats are reported in which cytology smears obtained by ultrasound-guided fine needle aspiration of the liver were interpreted as indicative of hepatic lipidosis. However, histopathology of hepatic tissue samples obtained with Tru-Cut-like needles or wedge biopsy revealed that the cats had inflammatory or neoplastic hepatic disease causing their clinical signs. Fine needle aspiration and cytology may not detect infiltrative lesions, particularly those that are nodular, multifocal, or localised around the portal regions. Fine needle aspirate cytology is a useful diagnostic procedure with many advantages, but care must be taken to avoid diagnosing hepatic lipidosis as the cause of illness when an infiltrative lesion is responsible.

An analysis of lymph node DNA for possible bacterial agents of cat-scratch disease.

Recent investigations have implicated Afipia felis and Rochalimaea henselae as possible agents of cat-scratch disease (CSD). We studied lymph nodes with necrotizing granulomas characteristic of CSD for A. felis and R. henselae DNA so that the relationship of these organisms to lymph nodes with necrotizing granulomas of unknown etiology might be better defined. We examined formalin-fixed, paraffin-embedded lymph node biopsies with necrotizing granulomas suggestive of CSD from 28 children obtained over the last 10 years. None had identifiable bacteria, fungi, or acid-fast organisms on routine staining. Pleomorphic bacillary structures consistent with the CSD bacillus were seen with the Steiner stain in 17 cases. We performed the polymerase chain reaction (PCR) on the extracted lymph node DNA with DNA primers for these organisms after demonstrating the presence of amplifiable DNA with c-K-Ras primers. R. henselae was identified in two samples. A. felis DNA was found in just one specimen. These putative CSD bacteria are infrequently associated with necrotizing granulomas using standard PCR techniques. It is possible that some of the patients did not have clinical CSD. The preservation of DNA or numbers of bacteria in the extracted sections may be inadequate for demonstration by DNA amplification methods. These bacilli may be responsible for a small proportion of these characteristic lesions of unknown etiology, or the typical CSD histology, including the presence of pleomorphic bacillary structures, may be nonspecific.
