HATS Off to MRSA
They had toyed with the idea for years, and now, Jacob, Tony, and Tom had finally made their dream of a family business a reality. With Jacob’s computer expertise, Tom’s experience from his marketing internship, and Tony’s apprenticeship with a master painter, the three brothers were confident that “Color Your World Painters, Inc.” would be a successful business venture. After only six months, their Internet and local TV advertising had made them a household name in their community. Tony had to hire additional painters to handle their burgeoning workload. The brothers moved to a larger office, purchased improved equipment, and issued all employees uniforms and painter’s caps with their flashy new logo.
Business that summer was booming. The hot, sweaty paint crew worked from sun up to sun down every day. Upon returning to headquarters, they hung their caps on the wall, changed out their uniforms for street clothes, and collected nice fat paychecks. Jacob boasted smugly that things couldn’t be better…until one morning Tony didn’t show up for work. Annoyed, Jacob grabbed a uniform and Tony’s hat, got the painters organized, and took his brother’s place on the work crew while Tom tried to track down Tony. Tom’s second phone call reached his five-year-old niece, who was answering her mother’s cell phone. In a small and tearful voice, she told her uncle that they were at the hospital and daddy was very sick because he had slime leaking out of his head. Confident that his niece’s imagination had run
away with her, Tom reassured the little girl and told her he would be right there. Tom left a voicemail message on Jacob’s cell phone and headed to the hospital. When he met his sister-in-law, Julia, Tom was shocked to find his brother was in surgery. Stunned, Tom listened to Julia describe the events of the last few days. Out of embarrassment, Tony never mentioned to his brothers that he periodically suffered from boils around his hairline when working under hot, humid conditions. Two days ago, when Tony noticed the first few boils appear, he assumed it was just a recurrence of his seasonal problem. But, after 24 hours, Tony was becoming concerned. This was the worst case he had ever experienced. He had at least a dozen boils on the back of his neck and into his hairline. Despite his discomfort, Tony continued work without complaint, although he secretly blamed his problem on wearing the new company cap that made him sweat more around his hairline.
That evening, Tony showed Julia his neck and asked her to help him disinfect and bandage the area. His frightened wife pleaded with him to go to the emergency room, but Tony flatly refused. Number one, they didn’t have health insurance and he certainly did want to run up a bill. But number two, Tony was not about to be humiliated by going to the hospital for something so simple. In his mind, boils could hardly be considered life-threatening. Julia gently cleansed the area for her husband, counting 13 boils the size of a dime or larger. Tony winced in pain.
1. What microbes commonly cause boils?
1. Staphylococcus aureus
2. What is another name for a boil?
1. Furuncle, Carbuncle
3. What is the incubation time for boil development?
1. 1 to 10 days
4. What factors are facilitating Tony’s problem?
5. What at-home cleansing and treatment options would you have recommended Julia try?
line. Tony found it humorous that his “gooey zits” got quick attention at an ED known for its long wait times. Dr. Bergmann, an infectious disease physician, examined Tony, noting heat, extreme erythema, folliculitis, 15 boils ~1–2 cm in diameter, some draining copious amounts of pus, and numerous seeping ulcerations. Dr. Bergmann applied a topical anesthetic before lancing several boils for culture. He ordered four sets of blood cultures drawn, started broad spectrum IV antibiotics, and immediately scheduled Tony for surgical debridement of his infection.
8. Why did the doctor lance boil to collect a specimen for culture when many others were already draining pus?
9. Why did Dr. Bergmann start Tony on antibiotics even though he didn’t know the microbe involved or its drug sensitivity?
10. Why were blood cultures ordered?
11. Why was Tony a candidate for immediate surgery?
Tom and Julia sat for about an hour in the waiting room before Dr. Bergmann arrived with an update on Tony’s condition. Preliminary Gram stain results from the lab confirmed Gram-positive clusters of cocci in Tony’s boils. Due to the extensive tissue damage, Dr. Bergmann confided to the family that he suspected community acquired-MRSA. Although Tony was “resting uncomfortably,” the surgical debridement of a 3.5 cm 10 cm area was a success. Tony would receive a three-week course of IV vancomycin before being permitted to return to work.
12. What common skin microbes demonstrate this Gram morphology and staining?
13. What does MRSA stand for?
14. What is the difference between community acquired-MRSA and hospital acquired-MRSA?
15. How does the resistance demonstrated by this organism differ from the resistance it typically shows to penicillin?
16. Why is vancomycin a good treatment choice when penicillin and methicillin are ineffective? 17. What complications are associated with IV vancomycin treatment?
18. Tony’s infection progressed rapidly and resulted in substantial soft tissue damage. Why is MRSA able to cause this problem?
