Antimicrobial Selection in the Face of Nasal Methicillin-Resistant Staphylococcus aureus-Polymerase Chain Recombination Testing in Thermal Injury Patients.

Emergence of resistance to vancomycin and the increasing incidence of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) warrant careful initiation of antimicrobial agents after nasal swab polymerase chain recombination (PCR) MRSA positive screen. Current MRSA PCR nasal swab (PCR) screening does not distinguish non-hospital-acquired strains. A retrospective, institutional review board-approved study of collected PCR screenings among 826 burn center admissions over a 23-month period assessed culture results, antimicrobial agents chosen, and patient demographics.

Evaluation of Aquacel Ag for Autogenous Skin Donor Sites.

An ongoing objective of burn research is to evaluate wound dressings and develop new treatments to expedite wound healing. This was a single-center, prospective, randomized, controlled study to evaluate the effectiveness of Aquacel Ag as a dressing for autogenous skin donor sites compared with Xeroform. We hypothesized that donor sites treated with Aquacel Ag would heal faster.

Pyoderma gangrenosum: a difficult diagnosis best managed in a burn treatment center.

Pyoderma gangrenosum (PG) is a rare immunological disorder with inexplicable white blood cell infiltration into the epidermis with necrosis and excruciating pain. Diagnosis is by exclusion which delays proper treatment. Surgical intervention often exacerbates wounds.

Evaluation of the relationship between elevated vancomycin trough concentrations and increased efficacy and/or toxicity.

Isolation of Staphylococcus aureus with minimum inhibitory concentrations, 1 to 2 mg/L, suggests increasing vancomycin trough ranges, from 10 to 20 mg/L or even higher. Vancomycin troughs from 604 treatment courses from 560 patients with suspected or actual Gram-positive infection were analyzed with focus on potential toxicity/efficacy. Trough concentrations were required to be drawn within 15 to 45 minutes before the administration of at least the third vancomycin dose.

Trimethoprim-induced hyperkalemia in burn patients treated with intravenous or oral trimethoprim sulfamethoxazole for methicillin-resistant Staphylococcus aureus and other infections: nature or nurture?

Trimethoprim is well known to cause rashes; however, what is not commonly known is that it causes sudden and profound hyperkalemia in 10 to 20% of treated patients. The uniqueness of burn patients begs the question whether changes known to occur in these patients might also increase this trimethoprim effect. After institutional review board approval, a retrospective study evaluated 224 patients with thermal injury who had been treated with trimethoprim sulfamethoxazole (TMP-SMX), 24 of whom had underlying renal impairment (creatinine clearances <50 ml/min) and were excluded, leaving 200 patients for analysis.

A comparison of clinical and microbiological efficacy of antibiotic regimens against Acinetobacter baumannii.

Acinetobacter baumannii represents a cunning pathogen with multiple resistance genes. The authors report their experience with the treatment of two multiple drug-resistant A. baumannii clones.

Use of nebulized antimicrobial agents in burned and mechanically ventilated patients with persistent Acinetobacter baumannii, Pseudomonas aeruginosa, or Enterobacteriacea.

Background: Nebulized antibiotics are used to locally treat colonizations of multi-resistant organisms. Prior systemic nephrotoxic antibiotic use with serum creatinine rises warranted an alternative therapy in 69 ventilator-dependent patients with persisting sputum cultures and need for ventilatory support.

Materials And Methods: Following IRB approval, retrospective patient data were reviewed.

Burn center management of operating room fire injuries.

Approximately 100 operating room (OR) fires occur per year in the United States, with 15% resulting in serious injuries. Intraoperative cautery was frequently associated with OR fires before 1994; however, use of supplemental oxygen (O(2)), ethanol-based products, and disposable drapes have been more frequently associated with OR fires. Fires resulting from cosmetic and other small procedures involving use of nasal canula O(2) and electrocautery have been described in six published reports.

Amlodipine-induced toxic epidermal necrolysis.

The objective of this study is to report a case of amlodipine-induced dermatotoxicity following treatment for diabetic nephropathy. Although other members of the dihydropyridine calcium channel blockers have been reported to cause dermatotoxic reactions, this is the first report attributing this effect to amlodipine. A 71-year-old diabetic and hypertensive woman had been noted to have worsened renal dysfunction and hyperkalemia attributed to enalapril, thus a trial of amlodipine was begun.

Quality assurance assessment of the use of linezolid in the treatment of thermal injury patients at a community teaching hospital.

We sought to evaluate the adverse effect profile of linezolid among thermal injury patients requiring treatment for Enterococcus species or other Gram-positive infection warranting treatment with linezolid. Seventy-six inhalation injury and/or thermal injury patients experiencing 94 exposures to linezolid for 48 hours or longer (range, 2-83 days) were included. We evaluated leukocyte count and platelet count for the time period preceding, during, and after therapy with linezolid based on specified time periods of exposure for evaluation of specific adverse effects.

Lamotrigine-induced toxic epidermal necrolysis in three patients treated for bipolar disorder.

Exfoliative dermatitis, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), is a mild-to-life-threatening process that has been described after exposure to many antiepileptic drugs. The increased use of antiepileptic drugs for treatment of bipolar disorder and neurologic disorders has extended the risk of exfoliative disorder to this population of patients, and these patients and their health care providers may not be familiar with the risks involved with these drugs. We describe the cases of a 28-year-old woman with bipolar 1 disorder initially treated with lamotrigine, and two adolescent girls with bipolar 2 disorder treated with lamotrigine after poor responses to other drug regimens.

Propofol withdrawal syndrome in an adult patient with thermal injury.

A 48-year-old man with a history of ethanol abuse and bipolar disease fell asleep while smoking in an intoxicated state. The patient received a 30% total body surface area burn involving his face and upper torso that resulted in an inhalation injury. Several attempts at weaning from mechanical ventilation failed due to his extreme agitation, which was unresponsive to benzodiazepines, opiates, and antipsychotic agents.

Emergence of resistance of vancomycin-resistant Enterococcus faecium in a thermal injury patient treated with quinupristin-dalfopristin and cultured epithelial autografts for wound closure.

Vancomycin-resistant Enterococcus faecium and faecalis (VRE) remains a major complication among critically ill patients. A 26-year-old patient with 65% total body surface area burns (TBSA) was infected with several E. faecium strains during his admission that were resistant to vancomycin.

Levofloxacin-induced toxic epidermal necrolysis in an elderly patient.

Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN) are mild-to-life-threatening adverse reactions that have been described after exposure to fluoroquinolones. No published reports, however, exist of exfoliative disease after treatment with levofloxacin. A 78-year-old woman with many medical problems, including chronic obstructive pulmonary disease, was treated with parenteral levofloxacin for community-acquired pneumonia.

Nontraditional dosing of ampicillin-sulbactam for multidrug-resistant Acinetobacter baumannii meningitis.

A 52-year-old man was admitted to a local hospital with headache, nausea, vomiting, dizziness, photophobia, and confusion after a sudden fall. Progressive changes in neurologic function were noted despite neurosurgical intervention and broad-spectrum antimicrobial coverage. Cerebral spinal fluid (CSF) culture identified Acinetobacter baumannii that was resistant to traditionally recommended therapies of amikacin and imipenem-cilastatin.
