As a Failure to Follow Basic Medical Rules for a Sample, Has a Costly Diagnosis of a Zoonosis

Cat-scratch disease can be transmitted from cats and dogs in winter. It is usually self-limited and caused by Bartonella henselae. It may cause serious symptoms, including neurological findings, especially in immune-deficient patients. A female patient was referred to our outpatient clinic at the age of 3 years and 10 months with a preliminary diagnosis of neurodegenerative metabolic disease. Her complaints began after a stray cat scratched her. We found out that the hospital to which she was admitted provided only local wound care due to her history of contact with a cat and that she was vaccinated against rabies. Her body temperature increased, her neck lymph nodes became swollen, and she developed otitis and mastoiditis after 1 month. Additionally, we discovered that she had deteriorated in her walking ability after 6 weeks and developed hand tremors after 10 weeks. It was discovered that previous centers to which the patient applied did not question cat contact. All metabolic tests performed for the differential diagnosis of last admission findings were considered nonspecific. Considering cat-scratch disease due to her clinical history, she was referred to the pediatric infection unit for a Bartonella henselae test, and the test result was 1/256 positive. Failure to follow basic medical rules might be costly in diagnosis and treatment. Cat scratch disease is a zoonosis and a major public health problem. In differential diagnosis, these medical procedures should always be considered before rare metabolic diseases.
