Background:Results from previous trials suggest that daptomycin may result in faster clinical improvement than penicillinase-resistant penicillins or vancomycin for patients with complicated skin and skin structure infections.Objective:The objective was to evaluate whether daptomycin treatment of cellulitis or erysipelas would result in faster resolution compared with vancomycin.Design:The study was a prospective, evaluator-blinded, multi-centre trial. Patients were randomised to receive daptomycin 4 mg/kg once daily or vancomycin according to standard of care for 7–14 days.Patients:Adults diagnosed with cellulitis or erysipelas requiring hospitalisation and intravenous antibiotic therapy were eligible for enrolment.Results:The clinical success rates were 94.0% for daptomycin and 90.2% for vancomycin (95% confidence interval for the difference, −6.7%, 14.3%). There were no statistically significant differences between treatment arms in the time to resolution or improvement in any of the predefined clinical end-points. Both daptomycin and vancomycin were well tolerated.Conclusions:There was no difference in the rate of resolution of cellulitis or erysipelas among patients treated with daptomycin or vancomycin. Daptomycin 4 mg/kg once daily appeared to be effective and safe for treating cellulitis or erysipelas.
Background/Aims: Compared to all other complications, literature data about vascular access aneurysm (VAA) are the scarcest. The aim of this cross-sectional study was to evaluate the prevalence of arteriovenous fistula (AVF) aneurysms and to confirm the risk factors for their appearance. Methods: The presence, number and morphological characteristics of AVF aneurysms were confirmed, and according to the score of AVF aneurysm (the sum of the length and width in cm), patients were classified into group 1 (score ≤12) and group 2 (score >12). Analysis included the last data from the medical records including vascular calcifications score. Results: Out of 181 patients, 150 with native fistula were included in this study. Aneurysmatic changes were detected in 90 (60%) patients, and the majority had two or more aneurysms. VAA were more frequent in patients with adult polycystic kidney disease (ADPKD) than in other diagnostic categories. By using forward stepwise logistic regression, we confirmed that patients on high-flux hemodialysis (HD) had 5.3-fold higher risk, and patients with diabetes mellitus had 5.8-fold less risk for developing AVF aneurysm. While vascular calcification score did not influence the incidence of VAA, higher PWV had significant negative influence on formation of AVF aneurysm (OR 1.25, 95% CI 1.003-1.56, p = 0.047). By ROC curve analysis, it was determined that patients who were longer than 5.7 years on HD had greater risk for developing VAA (area = 0.741, p = 0.000). Conclusion: This single-center study confirmed the very high prevalence of VAA (60%). Aneurysms were more frequent in patients with ADPKD and in those who had longer dialysis vintage on high-flux membranes with higher blood flow rate.
A group of 72 patients with 111 asymptomatic carotid stenoses (ACS), mean age 65.42 ± 9.21, and a group of 36 patients with 58 symptomatic carotid stenoses (SCS), mean age 67.63 ± 8.79, were analyzed prospectively during a 3-year follow-up period. All patients underwent color duplex scan sonography (CDS), carotid arteriography, computed tomography (CT) scan, and neurological examination. The aim of the study was to analyze the correlation between echo plaque morphology (degree and plaque quality), local hemodynamic plaque characteristics, ischemic CT findings, and onset of new neurological events and deaths. The results analysis showed significantly more ACS in the group of 30–49% stenosis (p < 0.001), but significantly more SCS in the group of 70–89% (p < 0.0001) and ≥90% stenosis (p < 0.05). Fibrous plaque was more frequent in the ACS group (p < 0.001), while ulcerated and mixed plaques were more frequent in the SCS group (both p < 0.0001). In the SCS group, a significantly higher frequency of increased peak systolic and end diastolic velocities was noted at the beginning and end of the study (both p < 0.01), as well as for contralateral common (CCA) or internal carotid artery (ICA) occlusion (p < 0.05 and p < 0.01, respectively), but reduced carotid blood flow volume (p < 0.05) only at the end of the study. In the ACS group, the best correlation with new neurological events and deaths was shown with positive CT findings, peak systolic flow velocity over 210 cm/sec, end diastolic flow velocity over 110 cm/sec, plaque stenosis ≥70%, plaque ulceration, mixed plaque (all p < 0.0001); stenosis ≥50% (p < 0.001); and reduced carotid blood flow volume (p < 0.05).
Background/Aim. Diabetic foot is the term for the pathological changes on foot in patients with diabetes. It is caused by diabetic angiopathy, polyneuropathy and osteoarthropathy. The treatment is complex and long-term and often leads to the loss of the extremity. The appliance of hyperbaric oxygen therapy (HBOT) has a lot more important place in adjuvant treatment of this disease. The aim of this study was to determine the influence of HBOT on the wound healing in comparison with the conventional treatment, the possibility of shortening the time of the treatment in patients with diabetic foot. Methods. In a fiveyear period a retrospective-prospective multicentric study, involving 60 patients with diabetic foot divided into two groups, was performed. The first group (group A) consisted of 30 patients treated by combined therapy (with medications, surgical therapy and HBOT). All the patients were receiving HBOT in the Special Hospital for Hyperbaric Medicine, CHM Hollywell-Neopren in Belgrade. The control group (group B) also consisted of 30 patients treated with medications and surgical therapy, but without HBOT. Results. The demographic data, the types of diabetes, as well as the Wagner classification stage of diabetic ulcers and radiography scans of changes in bones were equal in both groups. The median healing time of the Wagner grade III ulcer in the group A was 37.36 days [mean ? standard deviation (SD) = 65.6 ? 45.8 days], and in the group B 99.78 days (mean ? SD = 134.8 ? 105.96 days) and it was statistically significant (p = 0.074). The median time of recovery in patients of the group A with the Wagner grade IV was 48.18 days (mean ? SD = 49.7 ? 33.8 days), and in the group B 85.05 days (mean ? SD = 86.7 ? 71.6 days) and that was statistically significant (p = 0.121). The foot amputations were performed in both groups in 3 (10%) patients. In the group A there were no high amputations, whereas in the group B there were 4 (13.33%) below-knee amputations and 4 (13.33%) above-knee amputations which was highly statistically significant (p < 0.0001). Conclusion. In this study, HBOT definitely showed positive adjuvant role in the treatment of diabetic foot. For the good treatment result it is essential the timely and successful surgical treatment of the ulcer and the use of bandage with the healing dressings. In case of the clear signs of local infection, the antibiotic therapy according to the antibiogram is necessary.
Polymethylmetacrylate (PMMA) is an artificial resin that has a wide application in a number of medical disciplines, surgery included. The use of acrylate is limited due to its modest mechanical features. Hence in this study, as an 'in vivo' experiment on dogs, the usefulness of 'reinforced acrylate' in the form of armored acrylate plates in the surgery of fractured ribs in flail chest has been valued. In earlier studies we have shown that polymethylmetacrylate, when reinforced with non-alkaline glass fibers, has improved mechanical characteristics (bending, stretching and crash resistance) compared with not reinforced, or in any other way strengthened acrylate. In this study the value of armored acrylate plates (AAP) in the sanation of flail chest in dogs has been verified, as well as its good biological tolerability as a new implant material in dogs. An original approach to surgical reposition and osteosynthesis of fractured ribs in dogs has been determined. An innovative approach to rib osteosynthesis with acrylate plates can be an adequate model for its application in human patients with unstable flail chest, which is often the result of injury or tumor excision
