Cat-scratch disease in children at a medical center.

BACKGROUND: Cat-scratch disease (CSD) is a well-recognized, benign, self-limited regional lymphadenopathy occurring in immunocompetent patients. Several retrospective studies have demonstrated that CSD occurs at all ages, however, the disease appears to be more common in children. We conducted a retrospective case study of CSD in children presenting at our hospital, and reviewed the relevant literature. METHODS: The medical records for eight children (age range 4-13 years) diagnosed with cat-scratch disease at the Tri-service General Hospital in Taipei from September 1, 1986 to September 1, 2002 were retrospectively reviewed. Clinical manifestations, diagnostic methods, and treatment types were assessed. RESULTS: The male gender predominated (75%); the median age was 8.6 years. The latency period ranged from 7 days to 1 month, with a median diagnostic interval of 8.5 days. There were no deaths. All patients had lymphadenopathy, and the axillary node was the most prevalent site (62.5%). The most common locations for the scratch or inoculation lesions were the hands and/or fingers (62.5%). Three patients were diagnosed from clinical symptoms and history (37.5%), three from serological study (37.5 %), and two using biopsy or aspiration (25%). All patients were given antibiotic treatment. The most commonly used antibiotic was gentamicin (75%), with the average duration of treatment 8.7 days. The average hospital stay was 8 days, with the lymph-node size reduced relative to pretreatment baseline in all except one case. CONCLUSION: In our experience, the long-term prognosis for children with typical CSD is favorable, and gentamicin may be a good antibiotic option.

[Cat-scratch disease].

We report a case of fourteen years old boy with cat scratch disease. He was treated at Pediatric Clinic in January and February 2000. Cat scratch disease is benign infectious chronic disease which appears in all ages. It begins after contact with cat and its scratch. Yearly incidence of this disease for whole population is 0.77-0.86/100.000. The cause is bacillus Bartonella which is also called genus Rochalimaea. It is Gram negative, mobile, aerobe bacillus with ten flagellas on one pole. Our patient was admitted at hospital because of high temperature, paleness, fatigue, bad appetite and pains in his joint. Ultrasound and magnet resonance scans of liver and spleen showed enlarged but regulary contured liver and two focal changes with diameter 16 mm, 12 mm and 7 mm in spleen. All those focal changes were described as abscesses. Diagnose was set up according increasing titre of IF-Bartonella hensalae IgG 1:256 (positive). This diagnostic test was performed at Institute for microbiology and Immunology at Medical Faculty in Ljubljana. Disease had long lasting course, and was cured by antibiotics without surgical intervention.

Cat scratch disease in the United States: an analysis of three national databases.

OBJECTIVES: Current knowledge of the epidemiology of cat scratch disease is based primarily on information from case series. We used three national databases to obtain more representative data to determine the incidence and demographics of cat scratch disease. METHODS: Records coded with the diagnosis of cat scratch disease from two hospital discharge databases and an ambulatory care database were analyzed. Costs of diagnostic tests and hospitalization were obtained from a sample of providers and published data. RESULTS: The incidence of patients discharged from hospitals with a diagnosis of cat scratch disease was between 0.77 and 0.86 per 100,000 population per year. Fifty-five percent of the case patients were 18 years of age or younger. Males accounted for 60% of cases. Incidence varied by season; approximately 60% of case patients were discharged in the months September through January. The estimated incidence of disease in ambulatory patients was 9.3 per 100,000 population per year. On the basis of these rates, we estimated the annual health care cost of the disease to be more than $12 million. CONCLUSIONS: The rates and seasonality of cat scratch disease found in this study were consistent with previous reports. Adults represented a higher percentage of the total than reported in previous case series, suggesting that the disease may affect more adults than previously recognized.

Cytologic diagnosis of cat scratch disease (CSD) by fine-needle aspiration.

Cat scratch disease (CSD) is usually a benign, self-limited lymphadenitis, characterized by suppurative granulomas. It can, however, produce a wide spectrum of clinical symptoms and cytologic changes and be the source of diagnostic dilemmas. Identification of pleomorphic bacilli (PB) with silver impregnation stains aids in the diagnosis, but this has not been well documented in cytologic preparations or in cases without the classic morphologic changes. We reviewed 13 aspirations from eight patients (aged 13-36 yr) occurring over a 15 mo time period, all clinically or cytologically suspicious for CSD. Sites included: axilla (6), parotid (3), epitrochlear (1), neck (1), submental (1), and intraclavicular (1) nodes. Neoplasia was initially suspected clinically in 38% of the cases. All but two patients had cat exposure on subsequent interview. The cytologic differential included bacterial abscess and lymphoproliferative disorders in 31%. Neither granulomas nor suppurative inflammation were seen in all cases. Changes included: granulomas (77%), PMNs (62%), dispersed epithelioid histiocytes (46%), and suppurative granulomas (38%). A modified silver stain (Modified Steiner, Sigma Diagnostics, St. Louis, MO) was performed on all specimens. Silver positive organisms were seen in 69% of cases and were not limited to those preparations with suppurative granulomas. Fine-needle aspiration biopsy (FNAB) is an effective method for diagnosing CSD despite its heterogeneous appearance; and, when combined with clinical information and silver staining, may obviate the need for excision.

[Mediastinal form of cat-scratch disease].

The authors reported a case of Cat--Scratch Disease (CSD) in a 14-year-old boy; it was an unusual CSD by its mediastinal mass location. Histopathological lesions which appeared as pseudo-tubercular folliculi mislead us. Disease was finally diagnosed by biological exams: a strongly positive Hanger-Rose reaction and serological assays used for the diagnosis of psittacosis, ornithosis, lymphagranuloma venereum and trachoma. CSD is a common cause of chronic lymphadenopathy in children. In the majority of patients, CSD is a mild illness. Some unusual forms as Parinaud's oculoglandular syndrome, neurological lesions, osteomyelitis and exceptionaly mediastinal lymphadenopathy have been reported. 2 cases of the latest ones were already described.

Imprint cytology of cat scratch disease. A report of eight cases.

The cytologic features of cat scratch disease (CSD) from eight cases in imprint smears are presented. All patients were clinicopathologically diagnosed with CSD as follows: 1) a history of animal exposure was recorded 2 to 4 weeks before lymphadenopathy; 2) the disease occurred in the autumn and winter months; 3) a characteristic histopathology in the biopsied lymph node specimens was observed; and 4) Warthin-Starry silver stain-positive bacteria were detected in four of the seven cases examined. The characteristic cytologic finding was the presence of confluent epithelioid cells with nearby and central scattering of neutrophils against a background of polymorphic inflammatory cells. Furthermore, a varying number of medium-sized to large lymphoid cells with an appearance suggestive of monocytoid B lymphocytes (MBLs) were noted to be associated with the epithelioid cells. These cytologic findings closely paralleled the histologic patterns of epithelioid cell granulomas, with and without MBLs, which we have previously reported are probably associated with the disease.

Retinal and choroidal manifestations of cat-scratch disease.

OBJECTIVE: The ability to diagnose cat-scratch disease (CSD) has been facilitated greatly by the recent isolation and characterization of Bartonella henselae (formerly genus Rochalimaea) and Afipia felis and by the subsequent development of specific enzyme-linked immunosorbent assay (ELISA) serologic tests. This study will help define the patterns of posterior segment ocular involvement in patients with confirmed CSD. DESIGN: The study design is a retrospective case study and literature review. PARTICIPANTS: Two consecutive patients with acute visual loss from retinal manifestations of CSD participated. INTERVENTIONS: The diagnosis was confirmed by B. henselae ELISA testing. Patients underwent extensive medical and ophthalmic investigations to exclude other causes of retinal and choroidal disease. Ophthalmic investigation included fluorescein angiography and visual field testing. One patient received antibiotic therapy with cefotaxime, then with ciprofloxacin, and was treated with oral prednisone. The other patient was improving for several weeks before oral doxycycline was given. MAIN OUTCOME MEASURES: The clinical syndromes observed were studied over time using visual acuity, visual field, and clinical findings. Data were collated with cases from the literature. RESULTS: Unilateral neuroretinitis and an unusual macular retinitis developed in patient 1, as did bilateral small intraretinal white spots and a unilateral choroidal infiltrate that continued to develop while the patient received antibiotic treatment. Patient 2 had a branch arteriolar occlusion in relation to a perivascular retinal infiltrate and a few small, bilateral, intraretinal white spots. There was gradual resolution with visual improvement while the patient received the antibiotic treatment, although therapeutic efficacy could not be determined. Patient 1 also received oral corticosteroids. A detailed analysis of the literature placed these findings in context. CONCLUSIONS: An unusual, well-defined retinal opacification with features of both multiple retinal arteriolar occlusions and a low-grade retinitis was described. Several features also may occur in posterior segment CSD, including neuroretinitis, a retinal white spot syndrome, and focal choroiditis.

Cat-scratch disease and related clinical syndromes.

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.
