Bartonella (Rochalimaea) henselae is a common cause of cat-scratch disease. This newly identified bacterium is also the cause of several other clinical syndromes, including bacillary angiomatosis, bacillary peliosis hepatitis and splenitis, and acute and relapsing bacteremia. A high percentage of young cats carry B. henselae. Fortunately, serious complications of B. henselae infections are rare in immunocompetent patients. Cat-scratch disease is usually a self-limited illness that does not necessarily require antibiotic therapy. Severe or persistent cases respond well to several antibiotics, including erythromycin and doxycycline. Cat-scratch disease should be included in the differential diagnosis of serious neurologic disease, particularly when regional lymphadenopathy develops suddenly in a previously healthy patient who owns a cat. Treatment of uncomplicated central nervous system disease is generally supportive. Antibiotic therapy is reserved for patients with atypical or severe involvement, including encephalopathy and retinitis. Other internal and cutaneous manifestations of B. henselae infection have recently been described. These potentially life-threatening infections respond well to antibiotic therapy, even in immunocompromised patients.

An indirect fluorescent antibody test for Bartonella henselae, B quintana, and B elizabethae was performed in all 18 children who presented to our paediatric outpatient clinic with cat scratch disease over a six year period. Serum samples were taken on admission, after 15 days, and after six months. Diagnosis was confirmed in 15 patients (83%) and was based on seroconversion or a fourfold change of the antibody titre to B henselae in 12 patients and on a single high titre (> 128) in three patients. Lymphadenopathy was present in all patients, erythema nodosum in one, osteomyelitis in one, hepatitis in one, transverse myelitis in one, and liver or spleen granulomata, or both, in three patients. Cat scratch disease developed in autumn or winter in 12 patients. All had a history of physical contact with a cat. Our study shows that our clinical suspicion was accurate in the diagnosis of cat scratch disease in a high percentage of patients presenting to a hospital and that indirect fluorescent antibody testing for B henselae is a useful diagnostic tool.

Cat-scratch disease is a subacute, regional lymphadenitis syndrome that occurs mainly in children. The causative agent is Bartonella henselae. After an incubation period ranging usually between 1 and 2 weeks, red papules develop at the site of cutaneous inoculation and persist until the development of lymphadenopathy with some malaise. Cases with complications have been observed including Parinaud oculoglandular syndrome, encephalopathy, a variety of exanthems and granumatous hepatitis. Diagnosis is based on serologic tests and, when necessary, antimicrobial treatment can be considered. Incision and drainage should not be done.

Cat Scratch Disease (CSD) is a benign disease characterized by regional lymphadenopathy affecting most frequently the head and neck region in children and young adults. In the present paper, the authors describe four cases of CSD focusing on clinical history, diagnostic management and therapy. The main germ responsible for this lymph node disease is Bartonella henselae. Diagnosis is based on history, serology and histological findings. Clinical evolution is generally favorable despite the fact that complications occur in about 5% to 13% of patients including encephalitis, hepatitis and Parinaud's oculoglandular syndrome. Antibiotic treatment is only considered for highly symptomatic patients. Surgical excision of the lymphadenopathy is useful to establish the diagnosis when serology is not available and/or when the adenopathy become fluctuating. The authors emphasize the increasing incidence of patients with CSD in the ENT population and the algorithm for CSD disease affecting the cervical lymph nodes.

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.

Cat-scratch disease (CSD) is usually a self-limited illness, though atypical presentations of infection with Bartonella henselae can occur, including osteomyelitis, oculoglandular syndrome, and granulomatous hepatitis. We describe a 6-year-old boy who had atypical CSD osteomyelitis of the left proximal femoral metaphysis due to a cat scratch. This is the second paper to report serial serology of B henselae, and the second paper to identify plasma cells on histologic examination, compatible with chronic osteomyelitis. The diagnosis was made by clinical, serologic, and histologic examination. Sixteen cases of atypical CSD osteomyelitis have been reported in the English literature and are reviewed in this paper.
