From Gary Weiss, MD, Hawaii: 8 yo girl with a left medial elbow mass for 2 weeks. She had been treated with antibiotics for 2 weeks, with no response. Additional w/u revealed very elevated titers c/w BH, per orthopod she had been around cat. They ended up doing an open resection/drainage were concerned about extent of fluid/abscess potential.

Disease Injury Nutrition Poison ... Prevention Cat scratch disease Definition: Cat scratch disease is an infectious illness caused by the bacteria Bartonella , believed to be transmitted by cat scratches, bites, or exposure to cat saliva. This leads to swelling of the lymph nodes ( lymphadenopathy ) near the site of the scratch or bite. Alternative Names: CSD; Cat Scratch Fever; Bartonellosis; Bacillary angiomatotis (similar to CSD); Oroya fever - "Carrion's disease" (similar to CSD) Causes, incidence, and risk factors: Cat scratch disease is caused by Bartonella henselae . The disease is spread through contact with an infected cat, as a result of a cat bite or scratch, or contact with cat saliva on broken skin or the conjunctiva of the eye. Lymph node swelling begins about 2 to 3 weeks after exposure and may persist for months. Swelling may occur at the site of the initial infection followed by enlarged lymph nodes along the lymph drainage route from the injury site. Occasionally, nodes may form a fistula through the skin and drain. Cat scratch disease is one of the common causes of

Harrington, and Joseph Taboada Cat scratch disease (CSD) is caused by Bartonella henselae, a gram-negative bacterium. As the name suggests, it is carried by cats and is usually associated with catinflicted trauma, e.g., a scratch (in most cases) or a bite. Some 22,000 people reportedly have this disease each year, but its incidence is probably much higher because most cases are asymptomatic. Clinical CSD in humans typically is characterized by swollen, painful lymph nodes, usually those immediately proximal to the site of inoculation; lowgrade fever, muscle aches, and general malaise are common. In more than 90 per cent of cases the disease is mild and self-limited, and symptoms resolve without treatment within a few weeks to a few months. More severe disease that requires hospitalization does occur. Rarely, B. henselae

Cat Scratch Disease What is cat scratch disease? Cat scratches and bites can cause cat scratch disease, a bacterial infection carried in cat saliva. The bacteria are passed from a cat to a human after the cat licks its paws then scratches human skin. Rubbing the eyes after petting a cat's fur can also spread cat scratch disease. Young kittens younger than 1 year of age are more likely to scratch, increasing the likelihood of infection. What are the symptoms of cat scratch disease? The following are the most common symptoms of cat scratch disease. However, each individual may experience symptoms differently. Symptoms may include: a cat bite or scratch that does not heal or worsens over time painful or swollen glands, especially under the arms flu-like symptoms including headache, lethargy, decreased appetite, fatigue, joint pain, or fever body rash The symptoms of cat scratch disease may resemble other conditions or medical problems. Always consult your physician for a diagnosis.

Cat Scratch Disease in Humans By Dr. Margaret Muns, DVM In humans, cat scratch disease causes only mild illness. The symptoms include skin lesions, painful inflammation of the lymph nodes, fever, malaise, and generalized aching. Most cases of cat scratch disease do not require any treatment beyond supportive care. Cat scratch does not recur, so multiple infections within a household is rare. If a kitten is the suspected source animal, the likelihood of transmission lessens as the cat matures. Cat scratch disease typically begins after a scratch by a cat to the hand or forearm. The organism that causes the disease can also enter the skin through a pre-existing cut or sore. If the disease becomes severe, it can progress to a systemic or relapsing infection. A diagnostic test is not available to determine whether a particular cat is a carrier of cat scratch disease. Because the involved cat is healthy otherwise, euthanasia of the cat is not justified. Declawing the cat is also not recommended because infection can be transmitted through contact with open wounds that are unrelated to scratching. You should always wash any cuts, bites or scratches promptly with soap and water, and should also not allow a cat to lick any open wounds. Cat owners should discourage rough play with their cats, and children should be taught not to harass a cat to the point of scratching or biting.

87. CAT SCRATCH DISEASE CAT SCRATCH disease Bartonellosis, also known as Cat Scratch diseaseor Cat Scratch Fever, is an infectious disease of humans. Evidence http://www.pethealthcare.net/html/body_cat_scratch_disease.html

CAT SCRATCH DISEASE Bartonellosis, also known as Cat Scratch Disease or Cat Scratch Fever, is an infectious disease of humans. Evidence is increasing that perhaps the cat becomes infected with the causative organism, but it does not appear to produce any disease in the cat. Very little is known or understood about the role of the cat as a reservoir for this disease. What are the risk factors? A cat scratch is sometimes, but not always, associated with this disease. In one study, 99% of patients with CSD had exposure to cats. An increased risk of transmission is present when a kitten is involved, as opposed to adult cats. Most cases are reported in the fall and winter, but the reason for its apparent seasonality remains unknown. What are the clinical signs? Antibodies are proteins which are produced by the immune system in response to some stimulus. About 5% of the United States population is known to have antibodies to CSD. Interestingly, about 20% of U.S. veterinarians will test positive for CSD antibodies. Very few of those testing positive have actually had the disease. The majority have had inapparent infections or have been exposed to the CSD organism without any disease occurring. This is generally a mild disease in humans. Many people experience fever, chills, and lethargy which last only a few days. Unless the skin test is performed or the organism is cultured, it may be diagnosed as influenza. However, the more severe forms of the disease will produce very high fevers, marked lethargy, anorexia, and swollen lymph nodes, usually in the axillae (armpit) or groin. The lymph nodes may enlarge to the point of rupturing or they may need to be opened surgically to establish drainage and relieve pain.

Related Stories Next Story Source: American Society For Microbiology Date: Ticks Have Potential To Transmit Cat Scratch Disease WASHINGTON, DC - April 12, 2001 Cat scratch disease may no longer be the appropriate name for the malady caused by the bacterium Bartonella henselae. Researchers at the University of California, Davis, have discovered evidence of the organism in ticks, suggesting that the arthropod has the potential to transmit the disease. They report their results in the April 2001 issue of the Journal of Clinical Microbiology. "We cannot say for certain that ticks are vectors of these diseases, but at the least we can say they carry Bartonella DNA and could be potential vectors," says Dr. Bruno Chomel, Professor of Zoonoses at UC Davis and one of the investigators on the study. Working on the hypothesis that ticks may serve as a transmission vector for Bartonella bacteria, Dr. Chomel and his associates tested Ixodes pacificus ticks from the coastal range area of California (which includes the San Francisco area) for the presence of Bartonella DNA. "We found that almost 20% of the ticks were positive, a percentage that's even higher than for known tick-borne diseases like Borrelia burgdorferi (the cause of Lyme disease) or ehrlichia," says Dr. Chomel.

Cat scratch disease bacteria may be transmitted to cats by fleas While a cat scratch may be the most common vehicle for transmitting CSD to people, the common cat flea is probably the vector for cats. September 1996 The cat flea is a competent vector for Bartonella henselae, the organism that causes CSD, according to Jane Koehler, MD, of the University of California at San Francisco. Koehler and her colleagues at UCSF and the University of California at Davis performed two controlled studies that demonstrated that direct cat-to-cat transmission could not be demonstrated in the absence of fleas. "These data suggest that control of flea infestation may reduce the number of insects capable of transmitting B. henselae from cat to cat, and that in turn will reduce the feline reservoir from which humans can become infected via a cat scratch," Koehler said. Bacterium recently identified Cat scratch disease has been recognized since the 1950s but the bacterium that causes it, B. henselae has only recently been identified.
