Chapter 6, Problem 1CCS
Cavities Gone Wild
Five-year-old Daniel appears to be shy. He always looks at the floor, has no friends, never plays with the other children, and will rarely speak to adults. When he does speak, it is difficult to understand his broken enunciation. His skinny frame and the dark circles under his eyes make him appear malnourished. Daniel cries frequently and misses many days of school.
A speech specialist at school finds that only two of Daniel’s teeth are healthy; all the others have rotted away to the gum line. The little guy is in constant pain, and it hurts to chew. A doctor later determines that bacteria from the cavities in his mouth have entered his bloodstream and infected his heart, causing an irregular heartbeat and poor blood circulation.
- 1. How does knowledge of biofilms help explain the bulk of Daniel’s problems?
- 2. What can Daniel, his parents, and health care professionals do to cure his diseases?
- 3. What is the scientific name of the nutrient that Daniel’s parents should eliminate from his diet to help prevent a repeat of this condition?
- 4. A recent study has shown that brushing does more than clean plaque from the teeth; it also disrupts associations between oral bacteria. How does this simple act help prevent the formation of biofilms?

The Human Touch
“OK, guys, we’re late again.” Shaylene Boulay calls out to her two oldest sons, Nathan Jr., 10, and Carl, 12. Grabbing the lunches Nate Sr. packed, she walks out the back door. “Come on, Michael, school time!” Shaylene peers under the porch for her 5-year-old. Their house is only a mile from the waterfront, and he loves to race cars between their dog Bubba’s big paws in the cool sand underneath the porch. “Look at you!” As Shaylene dusts him off and heads to the truck, she notices that the rash of blisters on his leg is still bright red. “Must be ant bites,” she thinks.
“Have a good day!” Shaylene hands Nathan and Carl their lunches as they hop out of the truck at the middle school. Next stop, Oak Creek Elementary. As Michael starts to get out, clutching his brown lunch bag tightly, his kindergarten teacher comes rushing over. “Michael, what are you doing here today? Didn’t you give your mother the note from the nurse?”
“What note? Michael, honey, did you forget…
Kate Bradley, age 22, is an avid swimmer. She swims year-round at least 2 days per week. Kate has an extensive history as a young child of repeated ear infections. She even had surgical placement of polyethylene tubes (PE) twice in her younger years to help decrease her frequent ear infections. Lately, Kate has developed left ear pain. She does not have an increased body temperature but notices an increase in left ear pain upon movement of the pinna. She thinks the outer ear looks a bit swollen but doesn’t notice any drainage coming from the ear. Kate also has noted a couple of instances where her balance has been impaired. She calls her practitioner and makes an appointment to have her ear checked.
Describe the part of the ear that is most probably affected given the symptoms that Kate is experiencing.

- A 33 y/o male, owner of a strip club, shut the club down early on July 4th and brought his 11 y/o daughter down to the club. They were standing in the parking lot setting off firecrackers when a yellow sports car drove slowly by. A shot was fired from the car, striking the club owner in the left anterior shoulder. He collapsed into the street, his daughter screaming and crying. A passerby called 911. Upon arrival of paramedics, he was noted to take 2 gasping, irregular breaths, and then suffered cardiorespiratory arrest. CPR was initiated, IVs were placed, the patient was intubated, and rapidly transported to the hospital. No cardiac monitor was placed on the patient until arrival at the hospital, at which time he was noted to be in ventricular fibrillation. A Resuscitative Thoracotomy was performed and internal heart massage initiated. A bullet wound to the Descending Thoracic Aorta was found and emergently closed in the Emergency Department. The patient was defibrillated multiple…arrow_forwardElla is an attorney who has worked in private practice for 25 years. She estimates she works 70 hours/week between the office and the courtroom.

- A 61-year-old gentleman was well-know to his neighbors as a friendly man who liked to drink too much. Over the course of 4-6 weeks, the neighbors noticed a change in the man's personality. He was less friendly, seemed not to remember their names, when he did talk he complained of headaches (of which he had not complained before), and they even talked among themselves as to the unsteady gait and dragging foot they saw when he would leave his apartment. Speculation ranged from drinking yet more, to his excessive alcohol consumption just catching up with him, to a simple function of premature aging. When the neighbors didn't see the man for several days, they called the police. Unable to get any response, officers made entry, finding the man in bed, lying on his side, with his face hanging down toward the floor. He was dead. An open wound was noted just above the eyebrow, approximately 2 inches long, with undermining of its superior edge; tissue bridges were seen, as were areas of…arrow_forwardYvonne is a 13-year-old eighth grader who is a new student in an urban middle school. She recently moved into the area with her mother and her three siblings. The family moved to be nearer to Yvonne s grandparents after the breakup of her parents relationship. Yvonne is tall for her age and is bothered by the looks and sexual comments about her breasts from boys in her school. She has made few friends at the new school, because she needs to spend most of her free time taking care of her younger siblings while her mother waits tables to support the family. Her eighth grade academic work is a little more advanced than what she is usedto. She is having a hard time keeping up, particularly in science, which is her first period course. The teacher moves very fast, despite the fact that most of the students look glassy-eyed from too little sleep. What does this example illustrate about the ease of the adolescent transition for early-maturing girls like Yvonne?

Her cries and screams greatly concern him. When she scrunches up her legs, she is even hard to hold. This father seems particularly uncomfortable with the situation, but has a really strong desire to know what to do to make his daughter more at ease. It is a particularly busy day in the practice, and after the doctor has determined the problem is colic alone, she asks you to take some time with the father to demonstrate some techniques that might be helpful. What will you do? What will you suggest? How can you help put the father at ease? Explain. ***INCLUDE CITATIONS IN MLA 9TH EDITION PERDUE OWL***arrow_forward
