Wound antisepsis has undergone a renaissance due to the introduction of highly effective wound-compatible antimicrobial agents and the spread of multidrug-resistant organisms (MDROs). However, a strict indication must be set for the application of these agents. An infected or critically colonized wound must be treated antiseptically. In addition, systemic antibiotic therapy is required in case the infection spreads. If applied preventively, the Wounds-at-Risk Score allows an assessment of the risk for infection and thus appropriateness of the indication. The content of this updated consensus recommendation still largely consists of discussing properties of octenidine dihydrochloride (OCT), polihexanide, and iodophores. The evaluations of hypochlorite, taurolidine, and silver ions have been updated. For critically colonized and infected chronic wounds as well as for burns, polihexanide is classified as the active agent of choice. The combination 0.1% OCT/phenoxyethanol (PE) solution is suitable for acute, contaminated, and traumatic wounds, including MRSA-colonized wounds due to its deep action. For chronic wounds, preparations with 0.05% OCT are preferable. For bite, stab/puncture, and gunshot wounds, polyvinylpyrrolidone (PVP)-iodine is the first choice, while polihexanide and hypochlorite are superior to PVP-iodine for the treatment of contaminated acute and chronic wounds. For the decolonization of wounds colonized or infected with MDROs, the combination of OCT/PE is preferred. For peritoneal rinsing or rinsing of other cavities with a lack of drainage potential as well as the risk of central nervous system exposure, hypochlorite is the superior active agent. Silver-sulfadiazine is classified as dispensable, while dyes, organic mercury compounds, and hydrogen peroxide alone are classified as obsolete. As promising prospects, acetic acid, the combination of negative pressure wound therapy with the instillation of antiseptics (NPWTi), and cold atmospheric plasma are also subjects of this assessment.

Drug resistant patients undergoing epilepsy surgery have a good chance to become sensitive to anticonvulsant medication, suggesting that the resected brain tissue is responsible for drug resistance. Here, we address the question whether P-glycoprotein (Pgp) and multidrug resistance associated proteins (MRPs) expressed in the resected tissue contribute to drug resistance in vitro. Effects of anti-epileptic drugs (carbamazepine, sodium valproate, phenytoin) and two unspecific inhibitors of Pgp and MRPs (verapamil and probenecid) on seizure-like events induced in slices from 35 hippocampal and 35 temporal cortex specimens of altogether 51 patients (161 slices) were studied. Although in slice preparations the blood brain barrier is not functional, we found that seizure-like events predominantly persisted in the presence of anticonvulsant drugs (90%) and also in the presence of verapamil and probenecid (86%). Following subsequent co-administration of antiepileptic drugs and drug transport inhibitors, seizure-like events continued in 63% of 143 slices. Drug sensitivity in slices was recognized either as transition to recurrent epileptiform transients (30%) or as suppression (7%), particularly by perfusion with carbamazepine in probenecid containing solutions (43%, 9%). Summarizing responses to co-administration from more than one slice per patient revealed that suppression of seizure-like activity in all slices was only observed in 7 % of patients. Patients whose tissue was completely or partially sensitive (65 %) presented with higher seizure frequencies than those with resistant tissue (35 %). However, corresponding subgroups of patients don’t differ with respect to expression rates of drug transporters. Our results imply that parenchymal MRPs and Pgp are not responsible for drug resistance in resected tissue.

Arthrodesis of the proximal interphalangeal (PIP) joint of the finger is an established procedure for advanced osteoarthritis. As there are different techniques of fusion, it seems necessary to evaluate the results. Primary outcome of this review was to evaluate different arthrodesis methods of the PIP joint and describe different numbers of non-unions. Secondary outcome was to evaluate time to consolidation. Respective complications, if mentioned, were listed additionally. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The selected databases were PubMed, Medline, Embase, Google Scholar and Cochrane Library. Studies reporting outcomes of the arthrodesis with a defined technique and radiological consolidation were included. Complication rates and types were recorded. In total, 6162 articles could be identified, 159 full-texts were assessed and 64 studies were included. Methodological quality was assessed using Methodological Index for Non-Randomized Studies. A total of 1923 arthrodeses of the PIP joint could be identified. Twelve different surgical techniques were described, four of these techniques with compression at the arthrodesis site. The most frequently used techniques were K-wires (n = 743, 14 studies), tension-band (n = 313, 15 studies) and compression screws (n = 233, 12 studies). The lowest rate of described non-unions in compression techniques was 3.9% with the compression screw. The highest non-union rate of 8.6% was achieved by interosseous wiring. All the described techniques can achieve the goal of fusing an osteoarthritic joint. There is a tendency in the more recent literature for the use of compression techniques.

Objective: To describe the extent of use and in‐hospital outcomes of open and laparoscopic pyeloplasty for paediatric pelvi‐ureteric junction ( PUJ ) obstruction in the USA . Patients and Methods: Using the 2004–2008 N ationwide I npatient S ample, we identified 4590 paediatric patients (≤18 years old) who underwent open or laparoscopic pyeloplasty for PUJ obstruction at 195 hospitals. Multivariable regression models were used to test the associations between hospital and patient covariates (age, gender, race, primary health insurance), type of admission (emergent vs elective), and hospital characteristics (teaching vs non‐teaching status; rural vs urban location) with complications, length of stay ( LOS ), and total hospitalization costs. Results: During the 5‐year study interval, 4426 (96.4%) and 164 (3.6%) paediatric patients diagnosed with PUJ obstruction underwent open and laparoscopic pyeloplasty, respectively. The proportion of patients undergoing laparoscopic pyeloplasty gradually increased from 2.4% in 2004 to 4.4% in 2008, but this increase was not significant ( P = 0.22 for trend). On multivariable analysis, laparoscopic pyeloplasty was observed to have rates of postoperative complications (2.51 vs 5.00; P = 0.67), LOS (2.42 vs 2.75; P = 0.33) and total hospitalization cost ($9755 vs $8537; P = 0.24) similar to those of open pyeloplasty. Conclusions: While laparoscopic pyeloplasty was generally an infrequent operation performed for paediatric PUJ obstruction during the period studied, this minimally invasive surgery provided similar outcomes in terms of in‐hospital complications, LOS and total hospitalization costs. The results of this study inform policymakers about the comparative effectiveness of laparoscopic and open pyeloplasty.
