RESUMO
The clinical efficacy of polymyxins in severe infection caused by carbapenem resistant organism (CRO) has gradually been recognized, and the course of treatment is generally 2 to 4 weeks. The most common complications after intravenous injection are nephrotoxicity and neurotoxicity, however, there are few reports on the efficacy and safety of the long course use of polymyxins. A patient with carbapenem resistant Acinetobacter baumannii (CRAB) infection after neurosurgery was admitted to the department of neurosurgical intensive care unit (NICU) of Lanzhou University Second Hospital. As the family refused the excision of brain abscess and Ommaya reservoir placement, polymyxin B was given intravenous (3.0 mg·kg -1·d -1) combined with intrathecal (5 mg once daily) injection, and high-dose sulbactam (8 g/d) was intravenously injected for anti-infection therapy. Finally, the brain abscess was absorbed and the patient was successfully cured. The total course of polymyxin B was 69 days with a cumulative dosage of 7 500 mg. There were no complications such as polymyxin-related nephrotoxicity and neurotoxicity during the period, and no symptoms of respiratory inhibition or neuromuscular blockage were observed, but polymyxin-related skin pigmentation appeared about 1 month after intravenous administration of polymyxins B, which subsided after drug withdrawal. It is suggested that long course of polymyxins B is safe and effective for intracranial infection caused by CRAB.
RESUMO
Background: The advent of antimicrobial therapy has offered an important adjuvant to the prevention of surgical infection. In spite of vast accumulation of research and review published there are still conflicting views. Some study shows multiple doses require for the eradication of microorganisms in the wound. While numerous authors have reported that single dose of an appropriate antibiotic is effective, but there has been no direct comparison of one dose against three doses regimens. Objective was to study about effect and safety of single dose of antibiotic against routine multiple dose regimens in clean and clean-contaminated abdominal surgeries.Methods: Patients recruited in the study according to specific inclusion and exclusion criteria. The participants were divided in two groups: group I and group II. Group I was given single dose of injection cefotaxime. While another group was given 5 days course of injection cefotaxime and injection amikacin or injection ciprofloxacin and injection metronidazole. Postoperative wound was assessed by Southampton wound grading system.Results: The rate of wound infection on 3rd day was for 16.30% for group I and 13.82% for group II. The infection rate decrease on 7th post-operative day and it was 13.04% for group I and 11.7% for group II.Conclusions: Long course of antibiotic as prophylaxis has no added advantage. Good operative technique plays a major role in preventing infections. Single dose antibiotic regimen has comparable infection rate for clean surgical cases and it saves lot of money in this era of cost containment.
RESUMO
Background: Brain metastases are the most common intracranial malignancy in adults and their management poses a significant healthcare problem. Of the various options available, whole brain radiotherapy (WBRT) remains the mainstay of treatment. Nonetheless, there is a need to develop fractionation schedules for best symptom palliation and prolonged survival. This prospective study aims to compare treatment outcome in terms of overall survival in two different WBRT schedules and determine the prognostic factors affecting this outcome.Methods: Sixty previously untreated patients with symptomatic brain metastases were randomized in two arms of 30 patients each to receive WBRT. Arm A patients received 30Gy in 10 fractions (long-course) and arm B received 20Gy in 5 fractions (short-course). All patients were assessed during and after completion of WBRT at 1, 3, 6, 9 and 12 months.Results: At 12 months post WBRT, the objective response rate i.e. complete and partial response (CR+PR) was 6.67% in arm A and 13.34% in arm B (p=0.96). Both WBRT regimens showed similar survival (p=0.65). On multivariate linear regression analysis, age ≤65 years, Karnofsky performance score (KPS) ≥70 and lack of extra-cranial metastases were significantly associated with improved survival at the end of 12 months post WBRT. EORTC QLQ-C30 showed similar improvement in quality of life in both the arms (p=0.86).Conclusions: This study suggests comparable results in the two fractionation schedules. Therefore, short-course WBRT may be used as a more convenient option in favour of shorter hospital stay and lesser burden on RT machines.
