- Atrial fibrillation (AF) is a common arrhythmia among patients scheduled for open heart surgery and is associated with increased morbidity and mortality. According to international guidelines, symptomatic and selected asymptomatic patients should be offered concomitant surgical AF ablation in conjunction with valvular or coronary surgery. The gold standard in AF surgery is the Cox Maze III ("cut-and-sew") procedure, with surgical incisions in both atria according to a specified pattern, in order to prevent AF reentry circuits from developing. Over 90% of patients treated with the Cox Maze III procedure are free of AF after 1 year. Recent developments in ablation technology have introduced several energy sources capable of creating nonconducting atrial wall lesions. In addition, simplified lesion patterns have been suggested, but results with these techniques have been unsatisfactory. There is a clear need for standardization in AF surgery. The Swedish Arrhythmia Surgery Group, represented by surgeons from all Swedish units for cardiothoracic surgery, has therefore reached a consensus on surgical treatment of concomitant AF. This consensus emphasizes adherence to the lesion pattern in the Cox Maze III procedure and the use of biatrial lesions in nonparoxysmal AF.

- BACKGROUND AND AIMS: After resection and repair of the intestines, tissue degradation leads to weakening of the repair site and risk of postoperative leakage. Matrix metalloproteinases (MMPs) are thought to be responsible for collagenolysis in the direct vicinity of surgical sutures in many tissues. Several experimental studies show that MMP inhibitors administered systemically alleviate postoperative weakening of intestinal anastomoses. We hypothesised that local delivery of MMP inhibitors would achieve a similar effect. MATERIALS AND METHODS: Implementing a novel method for the coating of biomaterials, we coated sutures with a cross-linked fibrinogen film and bound the MMP inhibitor doxycycline into this film. The sutures were then used in a standard rat model for evaluating mechanical properties of colonic anastomoses 3 days after surgery. RESULTS: The breaking strength of the anastomoses on the critical third day after operation was 17% higher with doxycycline-coated sutures compared to controls (P = 0.026). Energy uptake at failure was enhanced by 20% (P = 0.047). CONCLUSION: Drug delivery by means of MMP-inhibitor-coated sutures appears to improve tissue integrity during anastomotic repair and may reduce postoperative complications.

- Introduction and hypothesis: Urinary incontinence (UI) is common among the elderly, but the literature is sparse on the surgical treatment of UI among the elderly. This systematic review aims to assess the effectiveness of surgical interventions as treatment for urinary incontinence in the elderly population ≥65 years of age.Methods: Randomized controlled trials (RCT) and prospective nonrandomized studies (NRS) were included. The databases PubMed (NLM), EMBASE (Elsevier), Cochrane Library (Wiley), and Cinahl (EBSCO) were searched for the period 1966 up to October 2013. The population had to be ≥65 years of age and had to have undergone urethral sling procedures, periurethral injection of bulking agents, artificial urinary sphincter surgery, bladder injection treatment with onabotulinumtoxin A or sacral neuromodulation treatment. Eligible outcomes were episodes of incontinence/urine leakage, adverse events, and quality of life.The studies included had to be at a moderate or low risk of bias. Mean difference (MD) or standard mean difference (SMD)as well as risk difference (RD) and the 95 % CI were calculated.Results: Five studies-all on the suburethral sling procedure in women- that fulfilled the inclusion criteria were identified. The proportion of patients reporting persistent SUI after surgery ranged from 5.2 to 17.6 %. One study evaluating quality of life (QoL) showed a significant improvement after surgery. The complication rates varied between 1 and 26 %, mainly bladder perforation, bladder emptying disturbances, and de novo urge.Conclusion: The suburethral sling procedure improves continence as well as QoL among elderly women with SUI; however, evidence is limited.

- Background: Neonatal Brachial plexus palsy is an injury during delivery that can lead to loss of motor function and limited range of motion in patients due to damage of nerves in the brachial plexus. This scoping review aims to explore types of procedures performed and assess outcomes of forearm and elbow secondary surgery in pediatric patients.Methods: Searches of PubMed, Cochrane, Cumulative Index to Nursing and Allied Health Literature, Web of Sciences, and Scopus were completed to obtain studies describing surgical treatment of elbow and forearm in pediatric patients with neonatal Brachial plexus palsy. 865 abstracts and titles were screened by two independent reviewers resulting in 295 full text papers; after applying of inclusion and exclusion criteria 18 articles were included. The level of evidence of this study is level IV.Results: Ten main procedures were performed to regain function of the forearm and elbow in neonatal brachial plexus birth palsy patients. Procedures had different aims, with supination contracture (6) and elbow flexion restoration (5) being the most prevalent. The variance between preoperative and postoperative soft tissue and bony procedures outcomes decreased and showed improvement with respect to the aim of each procedure category. For soft tissue procedures, a statistically significant increase was found between preoperative and postoperative values for active elbow flexion, passive supination, and active supination. For bony procedures, there was a statistically significant decrease between preoperative and postoperative values of passive and active supination.Conclusion: Overall, all procedures completed in the assessed articles of this study were successful in their aim. Bony procedures, specifically osteotomies, were found to have a wider range of results, whereas soft tissue procedures were found to be more consistent and reproducible with respect to their outcomes. Bony and soft tissue procedures were found vary in their aims and outcomes. This study indicates the need for further research to augment knowledge about indications and long-term benefits to each procedure.

- AIM: The aim of this paper was to review the literature on the clinical importance of monitoring intra-abdominal pressure (IAP) after ruptured abdominal aortic aneurysm (rAAA) repair. METHOD: The literature was searched for abdominal compartment syndrome (ACS) or intra-abdominal pressure and aortic aneurysm. Original articles were studied. Personal experiences were reported. RESULTS: The Consensus Documents of the World Society on the Abdominal Compartment Syndrome (wsacs.org), with their definitions and guidelines, constitute an important step forward for the possibilities to study this clinical entity. Few papers were published describing the problem specifically in the patient population operated on for ruptured abdominal aortic aneurysm (rAAA). The incidence was approximately 5% when the patients were not monitored with IAP, and above 10% when IAP was monitored. The incidence seems to be similar irrespective if open or endovascular repair is performed, though comparative prospective studies were not published. Patients with intra-abdominal hypertension (IAH) or ACS have higher mortality and more complications. If IAH is recognized early conservative treatment may be effective to prevent development of ACS. After ACS has developed, surgical decompression is usually required. A proposed algorithm on how to act on different levels of IAH is presented. CONCLUSIONS: IAH/ACS is an important complication after operation on patients with rAAA. Monitoring IAP may be associated with improved outcomes.

- The present knowledge on endovascular repair of ruptured abdominal aortic aneurysms (rAAA) prevents firm conclusions when to use this method in comparison to open repair. This review article briefly summarizes results from case series, and discusses how to achieve reliable information despite the absence of randomized controlled trials. At present a careful conclusion might be that dedicated centers with an adequate organization and reasonably high volume of abdominal aortic aneurysm (AAA) should use detailed registry protocols to achieve experience and data to create an as reliable basis as possible for future recommendations.

- PURPOSE: The aim of this investigation was to evaluate the clinical outcome of two different surgical protocols in the edentulous mandible: submerged and nonsubmerged. Further, the Paragon dental implant with a titanium plasma-sprayed surface was evaluated. MATERIALS AND METHODS: Twenty-nine consecutively treated patients with 168 implants supporting fixed prostheses were included. All but 3 patients were provided 6 implants, placed via nonsubmerged healing on one side and submerged healing on the other. Data were collected from patient records and radiographs. Twenty-four patients participated in the 5-year clinical follow-up examination. RESULTS: After 5 years, all patients still had their mandibular fixed prostheses in function. Cumulative survival rates were 100% for prostheses and 99.4% for implants. However, 3 implants fractured in 1 patient. One submerged implant was lost before loading but no further implants were lost during follow-up. The radiographic bone loss was small for all implants with a mean of 0.14 mm (standard deviation [SD]: 0.37) at 1 year and 0.42 mm (SD: 0.48) at 5 years for nonsubmerged implants and 0.17 mm (SD: 0.32) at 1 year and 0.51 mm (SD: 0.33) at 5 years for submerged implants. Nineteen implants (including the 3 that fractured) presented annual bone loss exceeding 0.2 mm after the first year, yielding a cumulative success rate of 86.2% after 5 years. CONCLUSION: Single-stage surgery was shown to have the same predictability as two-stage surgery in the anterior edentulous mandible. Paragon implants with a titanium plasma-sprayed surface showed a fracture rate of 2.2% and a success rate of 86.2% after 5 years.

Forskningsöversikt (refereegranskat)abstract
- The main objective of this review was to describe and quantify the association between Fusobacterium necrophorum (FN) and acute sore throat in primary healthcare (PHC).In this systematic review and meta-analysis, we searched Scopus and PubMed for case-control studies reporting the prevalence of FN in patients attending primary care for an uncomplicated acute sore throat as well as in healthy controls. Only studies published in English were considered. Publications were not included if they were case studies, or if they included patients prescribed antibiotics before the throat swab, patients with a concurrent malignant disease, on immunosuppression, having an HIV infection, or patients having another acute infection in addition to a sore throat. Inclusion criteria and methods were specified in advance and published in PROSPERO. The primary outcome was positive etiologic predictive value (P-EPV), quantifying the probability for an association between acute sore throat and findings of FN in the pharynx. For comparison, our secondary outcome was the corresponding P-EPV for group A Streptococcus (GAS).PubMed and Scopus yielded 258 and 232 studies, respectively. Removing duplicates and screening the abstracts resulted in 53 studies subsequently read in full text. For the four studies of medium to high quality included in the meta-analysis, the cumulative P-EPV regarding FN was 64% (95% CI 33% to 83%). GAS, based on data from the same publications and patients, yielded a positive EPV of 93% (95% CI 83% to 99%).The results indicate that FN may play a role in PHC patients with an acute sore throat, but the association is much weaker compared with GAS.

Vertebroplasty and kyphoplasty--a systematic review of cement augmentation techniques for osteoporotic vertebral compression fractures compared to standard medical therapy.

Forskningsöversikt (refereegranskat)abstract
- After more than two decades the treatment effect of cement augmentation of osteoporotic vertebral compression fractures (VCF) has now been questioned by two blinded randomised placebo-controlled trials. Thus many practitioners are uncertain on the recommendation for cement augmentation techniques in elderly patients with osteoporotic VCF. This systematic review analyses randomised controlled trials on vertebroplasty and kyphoplasty to provide an overview on the current evidence. From an electronic database research 8 studies could be identified meeting our inclusion criteria of osteoporotic VCF in elderly (age>60 years), treatment with vertebroplasty or kyphoplasty, controlled with placebo or standard medical therapy, quality of life, function, or pain as primary parameter, and randomisation. Only two studies were properly blinded using a sham-operation as control. The other studies were using a non-surgical treatment control group. Further possible bias may be caused by manufacturer involvement in financing of three published RCT. There is level Ib evidence that vertebroplasty is no better than placebo, which is conflicting with the available level IIb evidence that there is a positive short-term effect of cement augmentation compared to standard medical therapy with regard to QoL, function and pain. Kyphoplasty is not superior to vertebroplasty with regard to pain, but with regard to VCF reduction (evidence level IIb). Kyphoplasty is probably not cost-effective (evidence level IIb), and vertebroplasty has not more than short-term cost-effectiveness (evidence level IV). Vertebroplasty and kyphoplasty cannot be recommended as standard treatment for osteoporotic VCF. Ongoing sham-controlled trials may provide further evidence in this regard.
