Background: Diabetic and ischemic foot ulcers are difficult to heal, and the mastering of numerous treatment methods is imperative to achieve healing. One of these methods is the fillet toe flap used to cover specific diabetic wounds of the forefoot associated with toe osteomyelitis. Instead of amputating the infected toe, phalanges are removed while keeping the viable surrounding soft tissue. Methods: A systematic review was performed searching electronic databases up to October 2019 to identify relevant articles reporting the outcomes of the fillet flap in forefoot ulcers of patients with diabetes or peripheral artery disease. All study designs were included. The healing rate was the primary outcome. Secondary outcomes were the time to heal, ulcer recurrence, and complication rates of such infection, partial necrosis, and total necrosis. Results: The 8 studies that met the inclusion criteria were all case series or case reports, with a total of 28 patients including 29 flaps. The mean healing rate was 92.8% (2/29); in both cases, total necrosis was due to infection (7.2%). No ulcer recurrence or partial necrosis was noted. Conclusions: Though having limited indications, the fillet flap illustrates the full optimization of the available resources for wound coverage. The consistent presence of an axial vessel makes the fillet flap a reliable local flap to be used in specific circumstances where the loss of a toe is unavoidable. Further research is needed with large prospective controlled trials to support the findings of the review.

Background: The use of tissue plasminogen activator (tPA) for the treatment of frostbite has been reported and advocated, but its efficacy has not been well established. We conducted a systematic review to guide physicians on the role of tPA in the treatment of frostbite. Our hypothesis was that the use of tPA improves clinical outcomes, as measured by amputation rate. Methods: We searched MEDLINE (PubMed) and EMBASE for primary research articles on the use of tPA for the treatment of extremity frostbite. Information related to study design, outcomes, and complications was extracted. A total of 204 citations were screened, and then 35 abstracts and 24 reports were reviewed. Fifteen studies met the standard for final review. Results: One randomized, prospective study; 3 cohort studies; 8 case series; and 3 case reports were found. A total of 208 patients were treated. Differences in protocols, inclusion criteria, and outcomes measures prevented combining the study results. In all the studies, the authors reported that the use of tPA was or may have been useful in reducing amputation rates or increasing tissue salvage. Complication rates ranged from 0% to 100%, with a combined rate of 13%. The quality of the evidence was low. Conclusions: Due to the low scientific quality of the studies, the efficacy of tPA in reducing amputation rates cannot currently be established. Randomized, prospective trials or well-controlled cohort studies are needed to better assess the role of tPA. Consideration should be given to limiting its use to research protocols.

Takotsubo cardiomyopathy (TCM) is a condition that is characterized as a transient ventricular dysfunction in the absence of obstructive coronary artery disease (CAD) and is usually triggered by an acute medical illness or intense physical or emotional stress. Multiple cases of perioperative TCM (pTCM) have been reported from around the world, but a qualitative analysis of these cases has not yet been done. For this systematic review, we searched PubMed for case reports and case series of pTCM published from 1966 to April 2015 with the objective being to evaluate whether differences in demographics, clinical features and outcomes exist between pTCM and nonperioperative (npTCM), as well as to attempt to identify any predictors of the severe form of pTCM, which requires mechanical circulatory support (MCS) devices or leads to death. A total of 93 articles describing 102 cases were retrieved and reviewed. The findings were compared with the analysis of the International Takotsubo Registry by Templin et al and a systematic review of mainly non-perioperative TCM (npTCM) by Gianni et al. Although we were unable to identify definitive risk factors for pTCM, our review suggests that pTCM appears to occur in younger patients and with a lower likelihood of ST segment elevations and T-wave abnormalities than in npTCM. No demographic or clinical factors were identified that were predictive of more severe outcomes. As TCM in general can be a life-threatening event, it would therefore be prudent to consider pTCM within a differential diagnosis in any patient who decompensates in the perioperative period.

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term “cannabis arteritis” should be avoided until or unless more convincing scientific support is forthcoming.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

IntroductionAcute diverticulitis of the sigmoid colon is increasingly treated by a non-operative approach. The need for colectomy after recovery from a flare of acute diverticulitis of the left colon, complicated diverticular abscess is still controversial. The primary aim of this study is to assess the risk of interval emergency surgery by systematic review and meta-analysis.Methods and analysisThe systematic review and meta-analysis will be conducted in accordance to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement. PubMed/MEDLINE, Cochrane Central Register of Controlled Trials and EMBASE will be screened for the predefined searching term: (Diverticulitis OR Diverticulum) AND (Abscess OR pelvic abscess OR pericolic abscess OR intraabdominal abscess) AND (surgery OR operation OR sigmoidectomy OR drainage OR percutaneous drainage OR conservative therapy OR watchful waiting). All studies published in an English or German-speaking peer-reviewed journal will be suitable for this analysis. Case reports, case series of less than five patients, studies without follow-up information, systematic and non-systematic reviews and meta-analyses will be excluded. Primary endpoint is the rate of interval emergency surgery. Using the Review Manager Software (Review Manager/RevMan, V.5.3, Copenhagen, The Nordic Cochrane Centre, The Cochrane Collaboration, 2012) meta-analysis will be pooled using the Mantel-Haenszel method for random effects. The Risk of Bias in Non-randomized Studies of Interventions tool will be used to assess methodological quality of non-randomised studies. Risk of bias in randomised studies will be assessed using the Cochrane developed RoB 2-tool.Ethics and disseminationAs no new data are being collected, ethical approval is exempt for this study. This systematic review is to provide a new insight on the need for surgical treatment after a first attack of acute diverticulitis, complicated by intra-abdominal or pelvic abscesses. The results of this study will be presented at national and international meetings and published in a peer-reviewed journal.PROSPERO registration numberCRD42020164813.

Abstract Purpose Villoglandular adenocarcinoma (VGA) of the uterine cervix has been classified as a rare subtype of cervical adenocarcinoma with good prognosis. A conservative surgical approach is considered feasible. The main risk factor is the presence of other histologic types of cancer. In this largest systematic review to date, we assess oncological outcomes associated with conservative therapy compared to those associated with invasive management in the treatment of stage Ia and Ib1 VGA. Methods Case series and case reports identified by searching the PubMed database were eligible for inclusion in this review (stage Ia–Ib1). Results A total of 271 patients were included in our literature review. 54 (20%) patients were treated by “conservative management” (conization, simple hysterectomy, and trachelectomy) and 217 (80%) by “invasive management” (radical hysterectomy ± radiation, hysterectomy, and radiation). Recurrences of disease (RODs) were found in the conservative group in two (4%) cases and in the invasive group in nine (4%) cases. There was no significant difference in disease-free survival (DFS) according to conservative or invasive treatment (p = 0.75). The histology of VGA may be complex with underlying usual adenocarcinoma (UAC) combined with VGA. Conclusion The excellent prognosis of pure VGA and the young age of the patients may justify the management of this tumor using a less radical procedure. The histological diagnosis of VGA is a challenge, and pretreatment should not be based solely on a simple punch biopsy but rather a conization with wide tumor-free margins.

Abstract Cardiac troponins (cTn) are the preferred biomarkers for the evaluation of myocardial injury and play a key role in the diagnosis of acute myocardial infarction (MI). Pre-analytical or analytical issues and interferences affecting troponin T and I assays are therefore of major concern given the risk of misdiagnosis. False positive troponin results have been related to various interferences including anti-troponin antibodies, heterophilic antibodies, or elevated alkaline phosphatase level. On the other hand, false negative results have been reported in the case of a large biotin intake. These interferences are characterized with erroneous but reproducible troponin results. Of interest, non-reproducible results have also been reported in the literature. In other words, if the sample is reanalyzed a second time, a significant difference in troponin results will be observed. These interferences have been named “fliers” or “outliers”. Compared to the biotin interference that received major attention in the literature, troponin outliers are also able to induce harmful clinical consequences for the patient. Moreover, the prevalence of outliers in recent studies was found to be higher (0.28–0.57%) compared to the biotin interference. The aim of this systematic review is to warn clinicians about these non-reproducible results that may alter their clinical judgment. Four case reports that occurred in the Clinique of Saint-Luc Bouge are presented to attest this point. Moreover, we aimed at identifying the nature of these non-reproducible troponin results, determining their occurrence, and describing the best way for their identification.

Background: The current ongoing COVID-19 pandemic has compelled us to scrutinize major outbreaks in the past two decades, severe acute respiratory syndrome (SARS), in 2002, and Middle East respiratory syndrome (MERS), in 2012. We aimed to assess the associated neurological manifestations with SARS CoV-2 infection. Methods: In this systematic review, a search was carried out by key-electronic databases, controlled vocabulary, and indexing of trials to evaluate the available pertinent studies which included both medical subject headings (MeSH) and advance electronic databases comprising of PubMed, Embase, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL). Peer-reviewed studies published in English and Spanish were considered which reported data on the neurological associations of individuals with suspected or laboratory-confirmed SARS-CoV-2 infection. Outcomes were nervous signs or symptoms; symptom severity; and diagnoses. Findings: Our search identified 45 relevant studies, with 21 case reports, 3 case series, 9 observational studies, 1 retrospective study, 9 retrospective reviews, and 2 prospective reviews. This systematic review revealed that most commonly reported neuronal presentations involved headache, nausea, vomiting and muscular symptoms like fibromyalgia. Anosmia and ageusia, defects in clarity or sharpness of vision (error in visual acuity), and pain may occur in parallel. Notable afflictions in the form of anxiety, anger, confusion, post-traumatic stress symptoms, and post-intensive care syndrome were observed in individuals who were kept in quarantine and those with long-stay admissions in healthcare settings. SARS CoV-2 infection may result in cognitive impairment. Patients with more severe infection exhibited uncommon manifestations, such as acute cerebrovascular diseases (intracerebral haemorrhage, stroke), rhabdomyolysis, encephalopathy, Guillain-Barré syndrome. Interpretation: SARS-CoV-2 patients experience neuronal presentations varying with the progression of the infection. Healthcare professionals should be acquainted with the divergent neurological symptoms and to curb misdiagnosis and limit long term sequelae. Health-care planners and policymakers must prepare for this eventuality, while the ongoing studies increase our knowledge base on acute and chronic neurological associations of this pathogen.

Aims Local antibiotics are used in the surgical management of foot infection in diabetic patients. This systematic review analyzes the available evidence of the use of local antibiotic delivery systems as an adjunct to surgery. Materials and Methods Databases were searched to identify eligible studies and 13 were identified for inclusion. Results Overall, the quality of the studies was poor. A single trial suggested that wound healing is quicker when a gentamicin-impregnated collagen sponge was implanted at time of surgery, with no difference in length of stay or rate of amputation. Results from studies with high risk of bias indicated no change in wound healing when a gentamicin-impregnated sponge was implanted during transmetatarsal amputation, but a reduction in the incidence of wound breakdown (8% vs 25%, not statistically significant) was identified. A significant cost reduction was identified when using an antimicrobial gel to deliver antibiotics and anti-biofilm agents (quorum-sensing inhibitors) compared with routine dressings and systemic antibiotics. Analyses of case series identified 485 patients who were treated using local antibiotic delivery devices. The rates of wound healing, re-operation, and mortality were comparable to those that have been previously reported for the routine management of these infections. Conclusion There is a lack of good-quality evidence to support the use of local antibiotic delivery devices in the treatment of foot infections in patients with diabetes.
