Cat scratch disease with involvement of intra-parotid lymph nodes. Case report.
A case of cat scratch disease, presenting as a parotid tumor, is described. In its oculo-glandular form, this disease may be associated with swelling of the intraparotid lymph nodes, and the possibility should be considered in the differential diagnosis of parotid tumors in children. A careful history, and skin testing with cat scratch antigen, may aid in the diagnosis of this condition.
First isolation of Bartonella henselae type I from a cat-scratch disease patient in Japan and its molecular analysis.
We isolated Bartonella henselae from an inguinal lymph node of a 36-year-old male patient with cat-scratch disease. The patient had many areas of erythema on his body, swelling of the left inguinal lymph nodes with pain and slight fever. The diagnosis was made on the basis of polymerase chain reaction for B. henselae DNA from the lymph node biopsies and blood sample, and isolation of the organism, histology of the lymph node and serology with an indirect immunofluorescent antibody test. We also analyzed the genome profiles for five strains of 90 isolates from the lymph node by pulsed-field gel electrophoresis after Not I endonuclease digestion. We found two different genomic profiles. These results suggest that the patient had been either co-infected or re-infected with two genetically different strains of B. henselae.

[Kinetics of Bartonella spp. IgG antibodies in cat-scratch disease and in asymptomatic HIV-infected patients].
BACKGROUND AND OBJECTIVE: Our goal was to investigate the kinetics of serum IgG antibodies against Bartonella spp. in patients with cat-scratch disease and in HIV-infected indiviuals. PATIENTS AND METHOD: Sequential determinations were made in seven patients with cat scratch disease and in seven HIV-infected individuals who were seropositive for this bacteria. RESULTS: In five patients from each group, serum antibodies fell under the positivity threshold within two years. Two HIV coinfected patients harbored Bartonella spp. DNA in bone marrow. CONCLUSIONS: These results suggest that the finding of a positive titer of serum IgG against Bartonella spp. is a marker of acute or recent infection.
Transient paresis associated with cat-scratch disease: case report and literature review of vertebral osteomyelitis caused by Bartonella henselae.
Cat-scratch disease (CSD) rarely presents as vertebral osteomyelitis. We describe a case with paresis of the arm with total recovery after antibiotic and neurosurgical therapy. We reviewed 20 other cases of CSD vertebral osteomyelitis in the literature. This diagnosis should be considered in patients with systemic symptoms, back pain, and cat contact. The prognosis is generally good.
Cat scratch disease and bacillary angiomatosis: aetiological agents and the link with AIDS.
The recent characterisation of a new species of the genus Rochalimaea is the culmination of a ten year search for the identity of the agent of bacillary angiomatosis, a condition that is increasingly recognised in association with AIDS. This work has also implicated Rochalimaea henselae in the aetiology of cat scratch disease contact with cats is a risk factor for both conditions. This report describes both diseases and reviews progress toward understanding their microbiology. R. quintana is also implicated as an agent of bacillary angiomatosis and was recognised much earlier as the cause of trench fever.
Cat-scratch disease of the parotid gland: an often-misdiagnosed entity.
A case of cat-scratch disease involving the parotid area in a young adult is presented. Thanks to meticulous history-taking, the correct diagnosis was suggested and later established, thus preventing unnecessary surgery. The pertinent literature is discussed.
Cluster of five children with acute encephalopathy associated with cat-scratch disease in south Florida.
Between August 12 and September 27, 1994, five children in South Florida were hospitalized at a single hospital because of encephalopathy, presenting as status epilepticus, associated with cat-scratch disease (CSD). Diagnoses were confirmed by using an indirect fluorescent antibody test to detect antibody to Bartonella henselae, the causative agent of CSD. These cases represent the first cluster of CSD encephalopathy cases to be recognized in the United States. The patients lived within 7 miles of each other and all reported contact with pet or stray cats before developing regional lymphadenopathy and encephalopathy. All recovered fully. A high proportion of 124 cats from the local area were seropositive (62%) or bacteremic (22%). This study suggests that B. henselae can be associated with geographically focal clusters of CSD encephalitis and should be considered in the evaluation of children with acute encephalopathy.
[Three cases of bartonellosis (cat scratch disease)].
In the last years the number of Bartonella species has conspicuously increased, with better clinical and diagnostic definitions of the different related illnesses. We report, in the present article, 3 cases of cat-scratch disease, a particular bartonellosis mainly caused by Bartonella henselae which is transmitted by the cat. After an incubation period, cat-scratch disease clinically manifests as a regional lymphoadenitis, with the appearance of a small cutaneous lesion at the site of inoculation of the germ. The pathogenetic agent is susceptible to a number of antibacterial agents, such as penicillin, cephalosporins, aminoglycosides, tetracyclines, macrolides, quinolones, trimethoprim combined with sulphamethoxazole and rifampicin. The prognosis is usually favorable.

[2 patients with atypical manifestations of cat-scratch disease].
In 2 boys aged 8 years and 10 months, respectively, uncommon manifestations of cat scratch disease were seen. The first patient had acute encephalopathy: coma and generalized tonic-clinic convulsions. The second patient was presented with fever and peripheral lymphadenopathy in combination with hypodense lesions in the liver on ultrasound. Diagnosis was established on the clinical picture and the positive results of serological testing of antibody titres for Bartonella henselae. Both patients recovered completely within 2 months.
