Case Study #3b Scenario Karly is an emergency medical technician who is called to the home of Kevin, a 13-week-old boy who is having trouble breathing. Karly asked when Kevin had been last fed, and his mom reported that she had just switched him over to formula that she was making herself, from organic pasteurized cow’s milk, nonfat dry milk, and raw honey obtained from a local beekeeper. Kevin was transported by ambulance to the hospital and immediately placed on a ventilator.   Signs and Symptoms When Karly and the other first responders arrived at Kevin’s house, Karly immediately noticed that the boy did not seem to have any facial expression and that although his eyes were open, his eyelids were droopy and he did not seem to be focusing. The baby was also unable to grasp Karly’s finger and was very limp when she tried to pick him up. The medical term used to describe Kevin’s collective symptoms of lack of motion, no facial expression, and overall limpness is flaccid paralysis. This is commonly found in patients who have come in contact with a neurotoxin known as botulinum.  Question: This neurotoxin is most likely produced by:

Case Study #3a   Scenario Doug was a young single guy who on occasion had casual sexual encounters with women he met while out in bars. A few months after one such encounter, during a dentist’s appointment, the hygienist noted what looked like a series of small bumps on the back and side of Doug’s tongue, which had not been noted in his chart before.   Signs and Symptoms At his next visit, the bumps had expanded into lesions and Doug mentioned them as a concern. The dentist noticed that his tonsil on the side of the tongue lesions was swollen, as were the lymph nodes. He prescribed an antibiotic, which Doug took. The lesions didn’t get better but they also got no worse. A few weeks later Doug developed a stubborn sore throat, so he went to see his family physician.   Testing When Doug’s doctor saw the lesion at the back of his tongue, he sent Doug for an oral brush biopsy procedure. When the biopsied tissue was stained with hematoxylin and eosin stain, the pathologist noted a well-differentiated squamous cell carcinoma. A second sample was obtained by scalpel biopsy and tested for human papillomavirus (HPV) DNA, specifically HPV-16 and HPV-18. The results were returned as positive for viral DNA.   Question: Why did the antibiotics not improve Doug’s condition?
