Cat scratch disease: an infection beyond the lymph node.

Cat scratch disease is a cause of regional lymphadenitis that usually pursues a benign course. Most patients with cat scratch disease are children or adolescents. We report an adult patient with cat scratch disease complicated by osteomyelitis of the thoracic spine.

Multiple scattered granulomatous skin lesions in cat scratch disease.

We report a patient with cat scratch disease who presented with multiple scattered nodular lesions on the legs. Examination of skin biopsy specimens revealed a granulomatous pattern. In our opinion, this is a previously undescribed secondary cutaneous reaction of cat scratch disease. The pathogenesis of this reaction is unclear but some data suggest that the eruption might be caused by a hematogenous spread of cat scratch disease bacteria to the skin. Pathogenetic relationships with so-called bacillary angiomatosis, recently described in patients with acquired immunodeficiency syndrome, are reviewed here.

Nutritional and herbal therapies in the treatment of heart disease in cats and dogs.

Nutritional supplements such as L-carnitine and taurine have been found to be beneficial in dogs and cats with certain cardiac diseases. However, not all animals with cardiac disease respond to nutritional supplementation, which means that further work must be done to identify causes of cardiac disease. Herbal therapies have been used in dogs and cats based on information available from their use in humans. This paper reviews the possible benefits and side effects of L-carnitine, taurine, and herbal supplements.

Myocardial taurine concentrations in cats with cardiac disease and in healthy cats fed taurine-modified diets.

Myocardial taurine concentrations were measured in cats with cardiac disease and in healthy cats fed diets with various concentrations of taurine. Group 1 was composed of 26 cats with 3 categories of naturally developing cardiac disease: dilatative cardiomyopathy (group 1A), 10 cats; hypertrophic cardiomyopathy (group 1B), 9 cats; and volume overload (group 1C), 7 cats. These cats had been fed various commercial diets. Group 2 was composed of 40 healthy cats that had been fed diets varying in taurine concentration (0 to 1% taurine) for at least 2 years. Mean myocardial taurine concentrations did not differ significantly between group-1 cats with dilatative cardiomyopathy and those with hypertrophic cardiomyopathy or volume overload. Cats in group 1A had a mean myocardial taurine concentration 3 times higher than healthy cats fed a taurine-free diet (P less than 0.002). Mean myocardial taurine concentrations did not differ significantly between group-1A cats and healthy cats fed a diet containing 0.02% taurine; group-1A cats had significantly lower mean myocardial taurine concentrations than did healthy cats fed a synthetic diet containing 0.05 or 1.0% taurine (P less than 0.001). Acute oral administration of taurine in 5 group-1A cats appeared to increase mean myocardial taurine concentrations, compared with similar cats not given taurine during treatment for cardiac failure. In group-2 cats, mean myocardial taurine concentrations increased directly with percentage of dietary taurine.

Staggering disease in cats: isolation and characterization of the feline Borna disease virus.

A Borna disease virus (BDV)-like agent was isolated from the central nervous system (CNS) of cats with a spontaneous non-suppurative encephalomyelitis ('staggering disease'). In contrast to the rabbit-adapted BDV strain V, which can be propagated in several primary and permanent cell cultures, the cat virus grew only in embryonic mink brain cells. Infection of adult Wistar rats with feline brain tissue material did not result in clinical disease during a period of 5 months, nor in growth of infectious virus in the brain. However, using the brain suspension of a newborn rat inoculated with feline brain tissue material, it was possible to induce typical Borna disease (BD) in four adult rats. This indicates a possible adaptation of the cat virus during passages in rats. By the use of an RT-PCR technique, BDV-specific RNA could be detected in a majority of brain samples from diseased cats. BDV-specific antigen was demonstrated in feline CNS samples both by immunohistochemistry and ELISA. However, the amount of BDV RNA and BDV antigen was less in the cats as compared to horses with BD, providing further support for the notion that a distinct feline BDV strain exists.

Cat scratch disease: no longer a diagnostic dilemma.

Cat scratch disease is a relatively common cause of localized lymphadenopathy with about 80% of cases occurring in children. This self-limited infection is caused by a small pleomorphic gram-negative bacillus that has been identified in ocular granulomas, skin and lymph node specimens. Unusual manifestations of the disease, such as the oculoglandular disease of Parinaud, encephalopathy, or severe systemic disease, occur in about 12% of patients. Management consists of symptomatic treatment, occasionally aspiration of a node or selected antibiotic therapy in moderate to severely ill patients. Persistence of adenopathy for several months in a generally healthy patient with gradual, spontaneous resolution of the enlarged node is the natural course.

Cat-scratch disease: epidemiology, aetiology and treatment.

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 identified in 1983, having eluded detection for 50 years. Initially, Afipia felis was thought to be the cause; however, subsequent study failed to confirm a link. During the 1990s, it was demonstrated conclusively that Rochalimaea henselae, later reclassified as Bartonella henselae, was the cause of CSD. B. henselae has been isolated from bacteraemic cats, with transmission among cats thought to be via the cat flea. Although other Bartonella species are transmitted by arthropod vectors, it is unlikely that the cat flea is involved directly in human infection, but plays a role in amplifying the reservoir. B. henselae is difficult to culture, and either serology or the polymerase chain reaction are considered to be the best methods of detection. Genetic variation occurs amongst B. henselae strains, perhaps explaining the inconsistency of some diagnostic techniques. A separate serogroup (Marseilles) has been reported in a seronegative patient with CSD, and B. clarridgeiae has the potential to cause the disease. Atypical presentation is seen in up to 25% of cases, and manifests itself as ocular involvement, encephalopathy, granulomatous hepatitis, hepatosplenic infection, endocarditis and osteomyelitis. The majority of CSD cases resolve spontaneously and do not require antibiotic treatment. In complicated CSD, treatment with trimethoprim-sulphamethoxazole, ciprofloxacin or azithromycin is recommended, with gentamicin being reserved for the severely ill patient.

Cytologic features of necrotizing granulomatous inflammation consistent with cat-scratch disease.

Approximately 2,000 cases of cat-scratch disease are reported annually. It is an uncommon cause of unilateral lymphadenopathy in children and adults. We present the cytologic features of necrotizing granulomatous lesions consistent with cat-scratch disease from various sites. Eleven cases from 10 patients with a mean age of 16 yr (range, 2-33 yr) were biopsied by fine-needle aspiration. All gave a history of previous exposure to cats. Two children had atypical presentations; one with multiple hypodense areas within the liver and spleen, and the other with features of encephalitis. Other locations included lymph nodes from axilla, inguinal, preauricular, and cervical areas, and other body sites such as the scapula and the parotid gland. Histologic staging of the inflammatory process was correlated with cytologic features. There were 5 cases of early features, 3 cases in the middle phase, and 3 cases in late stage. The differential diagnosis of each stage is discussed. The 2 children with atypical presentations are described in detail.

[Cat-scratch disease as cause of Lymphadenitis colli].

Cat-scratch Disease as Cause of Lymphadenitis colli. Cat-scratch disease is a frequent cause of lymphadenitis colli. It mainly affects children and adolescents younger than 21 years. Since the clinical picture is not characteristic, a history of contact to cats or kittens is highly valuable for diagnosing the disease. Major aspects of the disease concerning epidemiology, diagnostic procedures, clinical presentation and therapy are discussed.

Fine needle aspiration cytology of cat scratch disease.

The cytologic features of cat scratch disease diagnosed by fine needle aspiration cytology of a right inguinal lymph node in a 23-year-old woman are reported. Characteristic granulomas, with peripherally palisading epithelioid histiocytes and centrally located neutrophils, and an associated polymorphic cell population were observed. The cytologic pattern closely parallels the expected histopathologic findings and therefore can suggest the diagnosis in unsuspected cases or can confirm the clinical impression. The cytologic differential diagnosis and a discussion of other granulomatous lymphadenitis are presented.

Use of silver staining (dieterlé's stain) in the diagnosis of cat scratch disease.

Lymph node involvement in cat scratch disease is characterized by a granulomatous lymphadenitis with micro-abscesses. Recently, it has been shown that the possible aetiological agent is a micro-organism which stains with some silver stains. In this study 60 lymph nodes were studied from 60 patients, using a modified Dieterlé's stain. In 40 cases (66%) rod-shaped bacilli with rounded extremities were observed. They were negative both with the Gram and Ziehl-Neelsen stains. Since such micro-organisms were demonstrated in the majority of the nodes examined, it can be concluded that silver stains are appropriate for the diagnosis of this condition.
