During 24 months in an uncontrolled, retrospective study of 268 patients with cat-scratch disease (CSD), 202 were treated with 18 different antimicrobial agents. Criteria for antibiotic effectiveness were established. One or two antibiotics were taken separately for at least 3 to 5 days by 202 patients with CSD. Outcome was determined by follow-up examinations and telephone. Effectiveness of antibiotic therapy was based upon 3 or more days of therapy and clinical improvement of the patient with absence of and/or a decrease in malaise, fatigue, fever, headache, anorexia, lymphadenopathy and, in 90 patients, a declining or normal sedimentation rate. Of 18 different antimicrobials prescribed, 14 commonly used antibiotics were judged to be of little or no value in treatment of CSD. Four antimicrobials were efficacious. Efficacy of the three oral drugs in decreasing order was: rifampin 87%, ciprofloxacin 84%, trimethoprim-sulfamethoxazole 58%. Gentamicin sulfate intramuscular was 73% effective. Antibiotic therapy can be considered for patients with severe cat scratch disease. Conservative, symptomatic treatment is recommended for the majority of patients with mild or moderate CSD.

We describe a renal allograft recipient with cat-scratch disease in whom refractory hypotension, severe metabolic acidosis, pulmonary infiltrates, and encephalopathy developed. The patient first presented with a history of cat bites and scratches, fever, headache, and arthralgias. Four weeks later, the clinical presentation of septic shock suddenly developed in the patient. Cat-scratch disease was documented clinically and by finding delicate pleomorphic bacilli in Warthin-Starry silver stains of biopsy specimens taken from the primary inoculation site and regional lymph node. The administration of intravenous sulfamethoxazole and trimethoprim, erythromycin lactobionate, and tobramycin sulfate therapy correlated with recovery. Although cat-scratch disease is usually a benign, self-limited illness, this article illustrates its systemic nature, its potential for devastating complications in the immunocompromised host, and its possible response to vigorous antibiotic therapy.

A psychiatric service had to be set up from scratch for a population of about 3 million people in Transkei when it became independent. This unusual requirement taught us certain lessons concerning the early diagnosis, management and after-care of patients admitted to Umzimkulu Hospital. Special mention is made of the alcohol-related mental disorders, depressive disorders and those associated with headache and convulsive seizures which were encountered, and the management and prevention thereof are commented upon.

We report a case of a 9-year-old girl scratched on the right side of her neck by a kitten about one month prior to admission. She was well until three weeks later when she developed enlarged right neck masses, a pustula on the scratch site, right injected conjunctiva, headache, general malaise and fever, thus fulfilling the clinical criteria for CSD. Initially, she was treated by a practicing physician but the manifestations persisted for one week. After admission, leukocytosis and a mildly elevated erythrocyte sedimentary rate were noted. The serum IgG titer to Bartonella henselae was performed by means of indirect fluorescent antibody (IFA) test at the National Institute of Preventive Medicine. The serum titer of anti-B, henselae Ig G was 1:256 and greater (> or = 1:256). The positive serum titer(negative titer being < 1:64) to B, henselae, the organism thought to be responsible for CSD, also supports this diagnosis. She was treated with a 7-day course of intravenous gentamicin and the fever subsided within 24 hours. Following this, she improved clinically and was discharged one week later. One month after discharge, she remained well with no palpable neck masses.

Shortly after adopting a 6-week-old cat, a veterinarian was bitten on the left index finger. Within 3 weeks, he developed headache, fever, and left axillary lymphadenopathy. Initial blood cultures from the cat and veterinarian were sterile. Repeat cultures from the cat grew Bartonella-like organisms with lophotrichous flagella. Sera from the veterinarian were not reactive against Bartonella henselae, B. quintana, or B. elizabethae antigens but were seroreactive (reciprocal titer, 1,024) against the feline isolate. Sequential serum samples from the cat were reactive against antigens of B. henselae (titer, 1,024), B. quintana (titer, 128), and the feline isolate (titer, 2,048). Phenotypic and genotypic characterization of this and six additional feline isolates, including microscopic evaluation, biochemical analysis, 16S rRNA gene sequencing, DNA-DNA hybridization, and PCR-restriction fragment length polymorphism of the 16S gene, 16S-23S intergenic spacer region, and citrate synthase gene identified the isolates as B. clarridgeiae. This is the first report of cat scratch disease associated with B. clarridgeiae.

To clarify the clinical manifestations of cat scratch disease (CSD), we evaluated a total of 130 seropositive patients with CSD. The patients' ages ranged from 1 to 68 years; 103 (79.2%) were under 18 years of age. CSD occurred predominantly in the fall and winter months. Regional lymphadenopathy was noted in 110 (84.6%) of the cases, and the most common sites were the neck (33%), axillary (27%), and inguinal (18%) regions. One hundred of the patients (77%) had general symptoms, such as fever, headache, and malaise. The clinical manifestations of CSD showed a wide spectrum from typical or classical CSD, with regional lymphadenopathy, to atypical or systemic CSD. Of the 130 cases, 103 (79.2%) were typical CSD and 27 (20.8%) were atypical CSD. Atypical cases of CSD were commonly reported as fever of unknown origin (37.0%), neuroretinitis (22.2%), encephalopathy (14.8%), hepatosplenic granuloma (11.1%), and Parinaud's oculoglandular syndrome (7.4%). Fever of unknown origin or prolonged fever lasting more than 14 days was evident in 27 (20.8%) of the 130 cases in this study. Eleven of the 27 cases lacked lymphadenopathy. Our findings suggest that CSD is not a rare disease in Japan. The indirect fluorescent antibody (IFA) test to detect Bartonella species may provide a prompt diagnosis of CSD and facilitate appropriate therapy.

Rat-bite fever (RBF) is a rare, systemic illness caused by infection with Streptobacillus moniliformis. RBF has a case-fatality rate of 7%-10% among untreated patients. S. moniliformis is commonly found in the nasal and oropharyngeal flora of rats. Human infection can result from a bite or scratch from an infected or colonized rat, handling of an infected rat, or ingestion of food or water contaminated with infected rat excreta. An abrupt onset of fever, myalgias, arthralgias, vomiting, and headache typically occurs within 2-10 days of exposure and is usually followed by a maculopapular rash on the extremities. This report summarizes the clinical course and exposure history of two rapidly fatal cases of RBF identified by the CDC Unexplained Deaths and Critical Illnesses (UNEX) Project in 2003. These cases underscore the importance of 1) including RBF in the differential diagnoses of acutely ill patients with reported rat exposures and 2) preventing zoonotic infections among persons with occupational or recreational exposure to rats.

Systemic cat scratch disease (CSD) is often associated with prolonged fever and microabscesses in the liver and/or spleen. We report a case of systemic CSD with hepatic, splenic and renal involvement in an aboriginal child in Taiwan. A previously healthy 9-year-old girl had an intermittent fever for about 17 days, and complained of abdominal pain, headache and weight loss. Abdominal computed tomography showed multiple tiny hypodense nodular lesions in the spleen and both kidneys. Laparotomy revealed multiple soft, whitish-tan lesions on the surface of the liver and spleen. Histopathologic examination of a biopsy specimen of the spleen showed necrotizing granulomatous inflammation with central necrosis surrounded by epithelioid cells and occasional Langhans' giant cells, strongly suggestive of Bartonella henselae infection. History revealed close contact with a cat. B. henselae DNA was detected by polymerase chain reaction in the tissue specimen, and the single antibody titer against B. henselae was greater than 1:2048. These results confirmed the diagnosis of visceral CSD caused by B. henselae. The patient's symptoms resolved after treatment with rifampin and tetracycline. This case illustrates the need for inclusion of systemic CSD in patients with fever of unknown origin and abdominal pain.

Cat scratch disease (CSD), caused by Bartonella henselae, is a zoonosis and characterized by self-limited lymphadenopathy. It is transmitted commonly by scratch or bite from cats or kitten. We report an unusual case of CSD caused by a domestic dog scratch that we believe is the first report in Taiwan. A 23-year-old healthy woman developed cervical lymphadenopathy, mild fever, headache, and malaise 3 days after dog scratch. Her symptoms improved after azithromycin treatment. Serology proved B. henselae infection. The owners of a domestic dog might be at risk of "cat" scratch disease.

Cat-scratch disease is one of several diseases known to be caused by Bartonella species. Some infections due to Bartonella resolve spontaneously without treatment with antibiotics, but in other cases the disease can be fatal without treatment. This case study reports a 7-year-old male who presented with an unexplained encephalopathy and unusual retinal findings associated with evidence supporting infection by B. henselae. The 7-year-old male presented with a 2-week history of general malaise and cervical lymphadenopathy progressing onto fever, headache, vomiting, and confusion associated with meningism. Lumbar puncture revealed a raised cerebrospinal fluid protein, low glucose, and raised white cell count. Abnormal retinal findings and raised antibodies titres to B. quintana indicated a diagnosis of cat-scratch disease. He was treated with azithromycin orally for 3 weeks and made a complete recovery.
