Aims The Exeter V40 cemented polished tapered stem system has demonstrated excellent long-term outcomes. This paper presents a systematic review of the existing literature and reports on a large case series comparing implant fractures between the Exeter V40 series; 125 mm and conventional length stem systems. Methods A systematic literature search was performed adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. In parallel, we performed a retrospective single centre study of Exeter V40 femoral stem prosthetic fractures between April 2003 and June 2020. Results There are 25 reported cases of such prosthetic fractures confined to small case series and case reports within the literature. We report an additional 19 cases to the literature (mean age 66.3 years (SD 11.7); 12 (63%) females; BMI 32.9 kg/m2 (SD 5.9)). The mean time from index procedure to fracture was 7.8 years (SD 3.6; 2.5 to 16.3). Exeter V40 stem fracture incidence was 0.15% and 1.21% for primary and revision arthroplasty, respectively. Incidence was significantly higher in revision arthroplasty (p < 0.001) and 125 mm length stems compared to ≥ 150 mm length stems (1.25% vs 0.13%, respectively; p < 0.001). When comparing different stem length cohorts, 125 mm short-stems were associated with stem-body fractures (92% vs 29%; p = 0.0095), earlier time to fracture (6.2 years vs 11.0 years; p = 0.0018), younger patient age at time of fracture (62.7 years vs 72.6 years; p = 0.037), and female sex (75% vs 43%; p = 0.326). Conclusion This complication remains rare, although we report a significantly higher incidence at up to 17 years follow-up than in the literature. Short 125 mm length Exeter V40 stems undoubtedly have a role in restoring anatomy and biomechanics in smaller femoral geometries, although the surgeon has to appreciate the higher risk of stem fracture and the associated predisposing factors which may necessitate particular attention to surgical technique and planning.

Repeated positivity and reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is a significant concern. Our study aimed to evaluate the clinical significance of repeatedly positive testing after coronavirus disease 2019 (COVID-19) recovery. We performed a systematic literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. With available individual patient data reporting on repeatedly SARS-CoV-2 positive (RSP) patients, case reports, and case series were included in this analysis. We performed a descriptive analysis of baseline characteristics of repeatedly positive cases. We assessed the cases according to the length of their polymerase chain reaction (PCR) negative interval between the two episodes. Risk factors for the severity of second episodes were evaluated. Overall, we included 123 patients with repeated positivity from 56 publications, with a mean repeated positivity length of 47.8 ± 29.9 days. Younger patients were predominant in the delayed (>90 days) recurrent positive group. Furthermore, comparing patients with RSP intervals of below 60 and above 60 days, we found that a more severe disease course can be expected if the repeated positivity interval is shorter. Severe and critical disease courses might predict future repeatedly positive severe and critical COVID-19 episodes. In conclusion, our results show that the second episode of SARS-CoV-2 positivity is more severe if it happens within 60 days after the first positive PCR. On the other hand, the second episode’s severity correlates with the first.

Background: COVID-19 has been shown to induce a hypercoagulable state thereby increasing the risk of arterial thrombosis resulting in Large Vessel Occlusion Stroke (LVOs) Objective: We performed a systematic review of published reports to study the clinical characteristics, and outcomes of COVID-19 acute ischemic stroke (AIS) patients with LVO treated with mechanical thrombectomy (MT) and compared them with historical controls. Methods: We conducted a systematic literature search from December 2019 to July 2020 using multiple combinations of keywords from PubMed and Ovid databases according to the PRISMA meta-analyses and systemic reviews guidelines and then pooled data from individual case series. We included studies where COVID -19 associated LVO cases were treated with MT and their clinical outcomes were reported. We then compared these findings with the historic patient data from the five landmark randomized MT trials, the Hermes collaborators (HC). Results: An initial search generated 12 studies but after excluding case reports and multiple reports comprising of the same series of patients, a total of five reports consisting of 51 patients were analyzed. The mean age of patients was 59 years (IQR 36-75), and 40 (78 %) were men. Median NIHSS on presentation was 20 (IQR 10-29). AIS with LVO was the presenting manifestation of COVID-19 in 16 (20%) of patients. Intracranial ICA was the most common site of occlusion found in 27 (53%) of patients with multi-territory occlusion in 10 (20 %). Final recanalization TICI ≥ 2b was achieved in 33 (64%) of patients but reocclusion was noted in 7 (14 %). Modified Rankin score (mRS) 0-2 was reported in 12 (23 %) of patients with 40 % in-hospital mortality. When compared to historic data from HC, COVID -19 patients were younger (59 vs 69 years), presented with a higher median NIHSS score (20 vs 17), and had a higher prevalence of ICA terminus occlusion (53% vs 21% ). Similarly, patient outcomes were poor in the COVID -19 group with mRs 0-2 in (23 % versus 46 %) and mortality (40 % vs 15 %) compared to Hermes group. Conclusion: COVID -19 AIS patients with LVO who underwent MT were younger, had multiple territory occlusions with a propensity for ICA terminus location, and had poor angiographic and clinical outcomes as compared to historic data.

Diagnosis of oral white lesions might be quite challenging. This review article aimed to introduce a decision tree for oral white lesions according to their clinical features. General search engines and specialized databases including PubMed, PubMed Central, EBSCO, Science Direct, Scopus, Embase, and authenticated textbooks were used to find relevant topics by means of MeSH keywords such as “mouth disease”, “oral keratosis”, “oral leukokeratosis”, and “oral leukoplakia”. Related English-language articles published since 2000 to 2017, including reviews, meta-analyses, and original papers (randomized or nonrandomized clinical trials; prospective or retrospective cohort studies), case reports, and case series about oral diseases were appraised. Upon compilation of data, oral white lesions were categorized into two major groups according to their nature of development: Congenital or acquired lesions and four subgroups: Lesions which can be scraped off or not and lesions with the special pattern or not. In total, more than 20 entities were organized in the form of a decision tree in order to help clinicians establish a logical diagnosis by a stepwise progression method.

AbstractAcupuncture has become increasingly popular in veterinary medicine. Within the scientific literature there is debate regarding its efficacy. Due to the complex nature of acupuncture, a scoping review was undertaken to identify and categorize the evidence related to acupuncture in companion animals (dogs, cats, and horses). Our search identified 843 relevant citations. Narrative reviews represented the largest proportion of studies (43%). We identified 179 experimental studies and 175 case reports/case series that examined the efficacy of acupuncture. Dogs were the most common subjects in the experimental trials. The most common indication for use was musculoskeletal conditions, and the most commonly evaluated outcome categories among experimental trials were pain and cardiovascular parameters. The limited number of controlled trials and the breadth of indications for use, outcome categories, and types of acupuncture evaluated present challenges for future systematic reviews or meta-analyses. There is a need for high-quality randomized controlled trials addressing the most common clinical uses of acupuncture, and using consistent and clinically relevant outcomes, to inform conclusions regarding the efficacy of acupuncture in companion animals.

Objectives: Biological medications have been used with an increasing frequency to treat rheumatological diseases. Autoimmune events can be induced by these drugs, such as psoriasiform lesions, alopecia, lupus and, vasculitis, which more often affects the skin (small-sized vessels) and eventually other organs. In this review, we describe the clinical profile of patients with vasculitis induced by the main biological agents used in rheumatology. Patients and methods: We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The PubMed database was used for searching eligible articles. We included case reports, case series, and letter to the editor of patients on anti-tumor necrosis factor-alpha (anti-TNF-a) molecules, as well as tocilizumab, ustekinumab, secukinumab, rituximab, and abatacept, who had vasculitis induced by these agents. Results: Eighty-one articles were included for final analysis (n=89). Twenty-seven patients were using infliximab, 20 adalimumab, 18 etanercept, seven secukinumab, four certolizumab, four rituximab, three golimumab, three ustekinumab, two abatacept, and one tocilizumab. Unspecific leukocytoclastic vasculitis (LCV) was the most common type of vasculitis (n=37), followed by anti-neutrophil cytoplasmic antibody (ANCA)- associated vasculitis (n=16). The medication was replaced with another biological molecule in 23 cases, with only four relapses. In six cases, the biological was maintained, but vasculitis worsened/persisted in one case, being necessary drug removal. Conclusion: Infections, infusion reaction, cancer, and autoimmune events are well-known side effects of biological therapy. This review demonstrates that vasculitis is another adverse effect of this type of therapy, particularly the anti-TNF-a molecules, and LCV the most reported type of vasculitis.

Objective: The objective of this article is to conduct a contemporary literature review on Wunderlich syndrome, or spontaneous renal haemorrhage (SRH), among pregnant women to describe contemporary aetiology, investigations and management patterns. Methods: A systematic review of MEDLINE and CENTRAL in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. All articles, including case reports and case series on SRH published from 2000 to 2016, were included. Full-text manuscripts describing SRH among pregnant women were reviewed for clinical parameters, which were collated and analysed. Results: Twenty cases of SRH in pregnant women were identified. The median age and gestation were 32.1 years and 26.5 weeks, respectively, with SRH most commonly occurring in the third trimester (nine patients; 45%) and due to renal neoplasm, specifically angiomyolipoma (AML; 12 patients; 60%), followed by renal artery aneurysm (RAA; five patients; 25%). Surgical intervention (55%) was most commonly used for acute SRH. Foetal demise was not uncommon (15%). Conclusions: SRH in pregnant women is an uncommon but complex urological and obstetric emergency with potentially catastrophic consequences. A multidisciplinary approach is key to timely diagnosis and appropriate management considering the well-being both of mother and foetus. Pre-emptive diagnosis and intervention may reduce complications. Level of evidence: 4

Objective: Both true and false extracranial carotid artery aneurysms (ECAA) are a potential source of morbidity and mortality. While ECAA have historically been treated surgically, endovascular reconstruction with stenting is an emerging treatment option. The aim of our study was to report clinical/radiologic outcomes following endovascular repair of ECAAs. Methods: A comprehensive systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: A total of 68 case reports and case series, comprising 162 patients, were included. Most patients presented with at least one symptom or sign related to the ECAA (89.5%; N = 145/162). In 42.6% (N = 69/162) and 46.3% (N = 75/162) of the cases polytetrafluoroethylene covered and uncovered stents were deployed respectively. Immediate post-procedural imaging demonstrated complete aneurysm exclusion in 86.4% (N = 140/162) of the cases and minimal filling of the aneurysm sack in 10.5% (N = 17/162) of all cases. Perioperative adverse event rates were 3.1% for stroke, 1.2% for transient ischemic attack (TIA) and 4.3% for mortality. During a mean follow-up of 21.8months, there were additionally observed one stroke, two TIAs and three deaths. Overall 88.6 % of the patients (N = 117/132) remained asymptomatic, partially recovered or at least did not suffer from new neurologic deficits during follow up, with no signs of stenosis or occlusion of the carotid artery. Conclusions: Endovascular stenting for the treatment of ECAAs is feasible with acceptable short- and long-term clinical and radiologic outcomes. Prospective real-world studies are needed to further validate the safety and the long-term patency of endovascular repair.

Background: Meta-analyses of case reports and case series of mechanical thrombectomy in childhood arterial ischemic stroke (AIS) suggest that mechanical thrombectomy is associated with good short-term outcomes in approximately three-quarters of children. Methods: Retrospective data on 38 children treated between 2010-2019 with mechanical thrombectomy for stroke were collected from former Thrombolysis in Pediatric Stroke (TIPS) sites. To minimize reporting bias, sites were required to report all patients ≤ 17 years treated with mechanical thrombectomy either at the study site or at an outside hospital prior to transfer. Short-term outcomes, defined as change in NIHSS prior to and following mechanical thrombectomy (MT), were compared with 85 children from case reports/case series published between 2010-2019. Results: The mean age of children from former TIPS sites was 11.9 years, 50% male, 34% treated with IV tPA prior to thrombectomy. The mean age of published cases was 10.4 years, 65% males, 19% treated with IV tPA prior to thrombectomy. Case reports had a wider distribution of before-MT NIHSS scores, and a steeper decrease in distributions of after-MT NIHSS scores than those from study sites within 24 hours of MT (Figure 1A; medians: 15 to 4 in published cases, 12 to 8 in cases from sites) and at discharge (Figure 1B; medians: 15 to 3 in published cases, 12 to 5 in cases from sites). Conclusion: Patients reported to former TIPS sites had discernably lower rates of good short-term outcomes compared with published case reports and case series, suggesting publication bias. Capturing key metrics of safety and effectiveness of MT in children with AIS, including variations in care delivery in actual practice, will be critical in the creation of evidence-based guidelines for acute management of pediatric AIS.

Abstract Introduction Suicidality and self-injurious behavior afflict patients with a wide variety of psychiatric illnesses. Currently, there are few pharmacologic treatments for suicidality and self-injurious behavior and none that treat these conditions emergently. Recently, ketamine has demonstrated efficacy in treating both depression and acute suicidal ideation. An increasing usage of ketamine, of a variety of formulations, has been studied for these indications. This article reviews the evidence for use of ketamine in self-injurious behavior and suicidality. Methods A review of the MEDLINE database for articles relating to ketamine, self-injurious behavior, suicidality, and self-harm was conducted. Additional articles were assessed via cross-reference. Results A total of 24 articles that included clinical trials, meta-analyses, case series, and case reports were analyzed. The majority of studies of ketamine for suicidal ideation include the intravenous route using a dose of 0.5 mg/kg over 40 minutes. These studies suggest that intravenous ketamine may be effective at reducing suicidal ideation acutely. Data on use of ketamine in the intramuscular, intranasal, and oral forms are limited and of poorer quality. Studies on these formulations contain greater variability of positive and negative results of ketamine for reducing suicidality and self-injurious behavior. The durability of the antisuicidal effects across all formulations is limited. Discussion Ketamine may be an effective option for the treatment of suicidal ideation in patients across inpatient, outpatient, or emergent settings. At this time, more research is needed on the efficacy of ketamine across all formulations being used in clinical practice.

Purpose. This study is aimed at synthesizing the available evidence regarding effectiveness of various modalities (combinations of LRS tasks) and comparison between each two modalities in terms of gingival display reduction, success rate, stability of the results, patient’s satisfaction, and postoperative morbidity. Materials and Methods. The electronic databases including PubMed, Scopus, Web of Science Cochrane Library, Google Scholar databases, ClinicalTrials.gov, and WHO International Clinical Trial Registry Platform were searched up to 27th June 2020 regarding lip repositioning surgery. The modalities were defined as the combinations of the following tasks: frenectomy (yes/no), flap thickness (full/partial), and myotomy (yes/no). Meta-analyses were performed on gingival display change from baseline to months 3, 6, and 12 in each modalities using Stata (v.16). Results. 38 studies (including three clinical trials, two quasiexperimental studies, seven case series, and 26 case reports) met the criteria for final inclusion. The mean gingival display reduced from baseline to 6 months ( WMD = − 2.90 , 95% CI: -4.85 to -0.95) in the patients undergoing the “frenectomy + full-thickness flap + myotomy” modality. This parameter decreased from baseline to 6 and 12 months, respectively ( WMD = − 2.68 , 95% CI: -3.49 to -1.86; WMD = − 2.52 , 95% CI: -4.40 to -0.64), in patients undergoing the “frenectomy + partial-thickness flap + without myotomy” modality. In patients who undergone the “without frenectomy + partial-thickness flap + without myotomy” modality, gingival display reduced from baseline to 6 months ( WMD = − 3.22 , 95% CI: -5.61 to -0.84). Almost 83% of patients with modality 1 had satisfaction. Conclusions. Gingival display within the 6 months after LRS could be reduced with all modalities. Descriptively, the greatest reduction was observed in patients with the modality not including the frenulum.
