Which of the following statements regarding MRSA is true? MRSA is strictly a nosocomial pathogen confined to hospitals and other long-term care facilities B buy 5 mg prinivil with mastercard. MRSA is more virulent than methicillin-susceptible S. Vancomycin is less effective than nafcillin for isolates sensitive to both agents D. There is no reported resistance to vancomycin for S. The vir- ulence and clinical manifestations of MRSA are no different from those of methicillin- susceptible S. With the increase in use of vancomycin, strains of S. Daptomycin and linezolid have excellent activity against van- comycin-intermediate and vancomycin-resistant Staphylococcus. A 34-year-old African-American woman presents to the emergency department complaining of fever, chills, pain in the right upper quadrant, and productive cough with blood-tinged sputum. She reports that she recently had a cold and that about 2 days ago she had a severe chill lasting about 20 minutes. Subsequently, she developed a temperature of 105° F (40. She reports that initially she was able to control the fever with antipyretics, but now the fever will not sub- side with medications. She reports that she has sickle cell anemia and that she smokes two packs of cig- arettes daily. On examination, she appears toxic; her temperature is 104. Chest x-ray shows a bronchopneumonic pat- tern in the right lower lung field. Sputum Gram stain reveals many polymorphonuclear leukocytes and abundant lancet-shaped gram-positive diplococci. For this patient, which of the following statements is false? The virulence of this infectious agent is related to surface protein A and penicillinase production B. The case-fatality rate for this infection is 5% to 12%; bacteremia is the most common extrathoracic complication, increasing the case-fatality rate to 20% D. This patient should be treated with ceftriaxone or cefotaxime until the results of susceptibility testing are available E. The capsule allows the bacteria to resist phagocytosis by leukocytes. Although the polysaccharide capsule is the critical factor in determining the virulence of the pneumococci, several proteins, including surface protein A, contribute to the pathogenesis of pneumococcal infections. Pneumococcal infections typically occur after a viral respiratory infection. Patients present with severe rigor or chill and pleurisy. Chest x-rays display findings of lobar consolidation or bronchopneumonic involvement. The key to diagnosis is Gram stain of a sputum smear, which typically reveals many polymorphonuclear leukocytes and abundant lancet-shaped gram-positive diplococci. Pneumococci display penicillin resistance, the mechanism of which is chromosomal mutation, not penicillinase pro- duction. Cigarette smoking is the strongest independent risk factor for invasive pneu- mococcal disease in immunocompetent adults who are not elderly.

Hard Tissue–Biomaterial Interactions 11 Figure 6 Allogenic bone chips. Dense connective tissue (CT) can be observed in close contact with the new bone trabecules. Figure 7 Hydroxyapatite particles in the periosteum elaborate significant osteoclastic activity. Hard Tissue–Biomaterial Interactions 13 Blood cells and osteoblasts are among the first cells to react to the implanted ceramic [105]. Ceramic particles do also interact with monocytes [106,107], and they are capable of stimulating the expression and secretion of cytokines and proteases that enhance bone formation and/or resorption [108]. Macrophages are presented to be the major infiltrating cells when HA and TCP are implanted [109]. These cells secrete H and degrade the ceramics [109]. Aluminum- containing ceramics, furthermore, significantly increase catalase activity and lipid peroxides in Figure 9 (A) Nonspecific inflammation after 1 week following implantation of porous HA particles into the bone marrow. Interleukin-1, IL-6, and TNF- secretion increases in human fibroblasts with HA particles. The action of HA particles was found to be at the level of transcription of such mediators. Gelatinolytic activity of the fibroblasts also increased with HA particles [108]. Hydroxyapatite sintered at low temperatures was found to cause more toxicity than that of HA sintered at higher temperatures [107]. Thus, new production methods of bioactive ceramics are under investigation [110] to overcome the toxicity problems. Toxicity of ceramics also depends on their solubility [111]. Natural ceramics are presented to be more effective in attracting cells and favoring their proliferation than synthetic ones [112]. Large amounts of mineral powder may also down-regulate osteogenic markers such as alkaline phosphatase activity and osteocalcin release (Fig. Bone mineral density gradually increases after HA implantation [114,115]. Thus, the me- chanical properties of HA-implanted bone differ from those of a normal bone. Stiffness properties of HA-implanted bone in compression do not change significantly throughout the healing pro- cess. The pattern of fracture in a defect-created control and HA-implanted bone differ from each other. The HA-implanted bone fractures from its end plates revealing a stiffer area at the implantation site that prevents the propagation of a longitudinal fracture. Control bone with the defect created, however, fractures longitudinally as the defect itself creates a weak point that allows the fracture to pass through it.

For this patient, which of the following statements regarding the treatment of prostate cancer is true? The only clear mortality benefit for radical prostatectomy is in patients with metastatic prostate cancer B. External-beam radiation therapy may be preferable to radical prostate- ctomy for patients with localized prostate cancer because of the signifi- cantly decreased incidence of erectile dysfunction in patients treated with radiation C. The standard treatment for patients with advanced prostate cancer is androgen ablation D. Chemotherapy for hormone-resistant prostate cancer typically includes docetaxel plus prednisone; this treatment has been shown to improve quality of life but not decrease mortality Key Concept/Objective: To understand the treatment of prostate cancer In the United States, radical prostatectomy has been the standard treatment for prostate cancer and may offer the greatest chance of cancer control for patients with organ-con- fined prostate cancer. Radical prostatectomy is associated with urinary incontinence and erectile dysfunction; the frequency and severity of these side effects are a source of debate. In comparisons between radical prostatectomy and external-beam radiation therapy, men who undergo radical prostatectomy are more likely to have urinary incontinence or impo- tence, although significant decreases in sexual function are seen with both treatments; men who receive external-beam radiation therapy are more likely to suffer changes in bowel function. For patients with advanced prostate cancer, the standard initial treatment is androgen ablation, a therapeutic strategy that involves either lowering the production of testosterone or blocking its binding to the androgen receptor. Androgen ablation is achieved by a variety of strategies. Castration or diminishing testosterone production can be achieved surgically with orchiectomy or chemically with luteinizing hormone–releas- ing hormone agonists. Chemotherapy has a clear role in patients with hormone-refracto- ry prostate cancer. Docetaxel plus prednisone is now the standard chemotherapy for men with metastatic prostate cancer. A 65-year-old man attended a community-based health fair, where it was discovered that his PSA level was elevated; he was referred to your clinic. The patient states that he has always been healthy and that he has not seen a physician for years. On review of systems, he does note some frequency, hesitancy, and urgency of urination, which he has been experiencing for the past few years. DRE reveals a smooth, sym- metrically enlarged prostate gland and brown guaiac-negative stool. Which of the following is NOT associated with elevated PSA levels? Prostatitis 12 ONCOLOGY 23 Key Concept/Objective: To know those conditions associated with elevated PSA levels Screening for prostate cancer by use of PSA has led to an increase in the number of cases of prostate cancer diagnosed in recent years and has enhanced the ability to detect organ- confined prostate cancer. However, some prostate cancers do not produce sufficient amounts of PSA to result in elevations in PSA serum levels, and there are several other con- ditions that can lead to elevations in PSA levels. These conditions include BPH, prostatitis, seminal ejaculation, and genitourinary instrumentation. Uncomplicated urethritis cannot lead to an elevation in PSA level. A 58-year-old patient of yours is diagnosed with prostate cancer after PSA levels were found to be ele- vated. Transrectal ultrasonography-guided biopsy is performed, and it is determined that the patient has adenocarcinoma of the prostate, with a Gleason score of 8. He asks you about his prognosis and the like- lihood that he will die of his prostate cancer. Which of the following patients is most likely to die of prostate cancer? A 75-year-old man with a Gleason score of 4 Key Concept/Objective: To know the key prognostic factors for patients with prostate cancer The Gleason grading system is the most commonly used method of classifying prostate can- cers. Tumors are graded from 1 (least malignant) to 5 (most malignant) on the basis of his- tologic findings.
