Abstract
Haemorrhagic pericardial cysts are rare and may be complicated by encasement of the heart, right heart failure and, rarely, cardiac cirrhosis. Surgical management of complicated cysts is challenging and has poor outcomes. We report a case of successful surgical management of a complicated pericardial cyst presenting with cardiac cirrhosis and the challenges associated with this condition.

Yong CW, Tan SHX, Teo GN, Tan TS, Ng WH. Should we stop dual anti-platelet therapy for dental extractions? An umbrella review for this dental dilemma. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2022; 123:e708-e716. [PMID: 35691560 DOI: 10.1016/j.jormas.2022.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 05/28/2022] [Accepted: 06/08/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Dual Anti-platelet Therapy (DAPT) are prescribed to patients who had or are at risk of cerebrovascular or cardiovascular ischemic events. This umbrella review appraises existing systematic reviews on the risk of bleeding related complications during and after dental extractions for patients on DAPT. STUDY DATA AND SOURCES This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered to the PROSPERO (International prospective register of systematic reviews) database. A systematic electronic literature search was conducted according to the PRISMA guidelines, via PubMed, Ovid, Cochrane and Embase. STUDY SELECTION Four systematic reviews met the inclusion criteria and were included the analysis. They show DAPT increases the risk of bleeding related complications after dental extractions, but the differences may not be clinically significant as local haemostatic measures were adequate in controlling bleeding. CONCLUSION Despite the increased risk of bleeding after dental extractions in patients on DAPT, it may not be necessary to interrupt the anti-platelet therapy. Local haemostatic agents may be sufficient in controlling both the primary or secondary bleeding. On the other hand, the complications of discontinuing DAPT may be more severe and fatal.

Abstract
Background Placenta accreta spectrum (PAS) describes the abnormal adherence of the placenta trophoblast to the myometrium and is associated with high foeto-maternal morbidity and mortality. This study was aimed at determining the prevalence, and trend of placenta accreta spectrum (PAS), as well as its association with sociodemographic/obstetrics factors at the Rivers State University Teaching Hospital (RSUTH). Methodology An analytical cross-sectional study of all recorded cases of placenta accreta spectrum managed at RSUTH from 1st January 2016 to 31st December 2021. Descriptive and inferential statistics were derived using IBM, Statistical Product and Service Solution (SPSS) version 25.0 Armonk, NY. Results There were 14195 deliveries, 137 cases of placenta praevia and 39 cases of placenta accreta spectrum. The prevalence of PAS at the RSUTH was 0.27% or 2.7 /1000 deliveries or 1in 370 deliveries. The rate of PAS among cases of placenta praevia was 28.5% or 1 in 4 cases. More than half of the variants of PAS were accreta 23 (59.0%) while 13(33.3%) and 3(7.7%) were increta and percreta respectively. The mean (SD) age and gestational age of the participants were 32.28 (± 5.13), [95% Confidence Interval (CI): 30.63, 33.92] and 36.43(±2.01), (95%CI: 35.18, 37.07) respectively. The modal age group was 35-39 years. The median blood loss was 650mls range of 450-2000mls. The majority of the study participants were booked 34(87.2%) and had secondary level education 17(43.6%). History of a previous caesarean section was statistically significantly associated with PAS P<0.001 while other factors did not attain significance. Conclusion Placenta accreta spectrum is not uncommon among women with pregnancies complicated by placenta praevia at the RSUTH. PAS occurred more among booked multiparous women with secondary level education and with an increasing trend. History of previous caesarean section is strongly associated with PAS.

Abstract
PURPOSE The aim of this study was to describe the utilization of the RAPTOR suite (hybrid theatre) for trauma patients. Ideally, this is used to achieve haemorrhage control in time-critical patients that may require damage control surgery (DCS) and/or interventional radiological (IR) procedures concurrently. METHODS A single-centre, retrospective study identifying all trauma patients that were treated at the level I trauma centre during 2011-2016 was performed. Patients that underwent treatment in the RAPTOR suite were described. Subgroup analyses were performed for trauma patients that underwent interventions within 60 min and patients who underwent a combination of DCS + angioembolization in the RAPTOR suite or in other locations (OR, radiology). RESULTS Since its introduction in 2011, 1% of all procedures performed in the RAPTOR suite were trauma related. From 2011 until 2016, 43 trauma patients underwent treatment in the RAPTOR suite. The majority of patients (81%) suffered blunt injury. Most patients were male (70%), with a mean age of 43 years. The mean ISS was 38. In 56% (n = 24) the MTP was activated and in 40% (n = 17) a CT scan was performed prior to treatment. Damage control surgery alone, angioembolization alone and a combination of DCS and angioembolization were performed in 37% (n = 16), 23% (n = 10) and 40% (n = 17) of patients, respectively. Median time to the hybrid suite, procedure time and total time were 56 min (15-704), 160 min (42-404), and 251 min (93-788), respectively. CONCLUSION In the first 5 years following introduction of a hybrid theatre in an urban level I trauma centre, only 1% of patients using the resource has injury-related pathology. Earlier identification of patients requiring this facility may improve timely access and management for this select group of patients needing urgent control of bleeding.

Abstract
PURPOSE Severe haemorrhage is a leading cause of early mortality following major trauma. By early identification of patients at risk, blood transfusion could already be initiated in the prehospital period. Aim of the study was to evaluate the extent to which prehospital lactate and base excess, which are known to be associated with trauma-induced coagulopathy, and additional clinical parameters are associated with the need for early transfusion. METHODS In this prospective, single-centre observational study, trauma patients treated by a helicopter emergency medical service were included, regardless of the injury severity. Patients with coagulation-influencing drugs in long-term therapy were excluded. Blood samples obtained at the beginning of the prehospital treatment were analysed. Primary outcome was the association of lactate and base excess with the need for early transfusion (resuscitation room or immediate surgery). Receiver operating characteristic curves were created, and the area under the curve (AUROC) was calculated. RESULTS Between 2015 and 2018, 21 out of 130 adult trauma patients received blood products during the early in-hospital treatment. Both prehospital lactate and base excess were associated with the transfusion (AUROC 0.731 and 0.798, respectively). The optimal calculated cut-off values were 4 mmol/l (lactate) and - 2.5 mmol/l (base excess). When circulatory instability and suspected relevant bleeding were included, the association further improved (AUROC 0.871 and 0.866, respectively). CONCLUSION Prehospital lactate and base excess could be used in combination with other clinical parameters as indicators of the need for early transfusion. This relationship has yet to be confirmed in the current validation study. TRIAL REGISTRATION German Clinical Trials Register, www.drks.de (No. DRKS 00009559).

Abstract
Major trauma networks reduce mortality in critically injured patients. Trauma patients should be appropriately triaged straight from the scene of injury, avoiding secondary transfer from a trauma unit. Selection criteria in regionally agreed triage tools are designed to identify which patients should be taken directly to the major trauma centre. Patients with life-threatening injuries still arrive at 'trauma units' in circumstances such as self-presentation, under triage, physiological instability or long journey time to the major trauma centre. This article presents a theoretical case of a haemodynamically unstable patient with penetrating injuries, and discusses the management of chest trauma, including diagnosis of life-threatening injuries, resuscitation strategies and definitive surgical management. Secondary transfer to the major trauma centre should be considered after instituting the minimal life-saving interventions. What constitutes a life-saving intervention requires an individual dynamic risk assessment and an understanding of major trauma networks.

Abstract
INTRODUCTION The management of patients with inherited bleeding disorders in oral surgery requires the systematic evaluation of bleeding risk and the setting up of an adequate treatment protocol by the referring haematologist, defining a replacement therapy and a recommended length of hospital stay. The purpose of this study was to determine the bleeding risk associated with oral surgery for each type of inherited bleeding disorder and to evaluate the efficacy of the treatment protocols set up in our tertiary care center. MATERIALS AND METHODS We included all patients with an inherited bleeding disorder, managed in our oral and maxillofacial surgery department with a treatment protocol set up by our local Haemophilia Treatment Centre for an oral surgical procedure. RESULTS Between January 2006 and December 2018, 295 treatment protocols were set up for the management of patients with haemorrhagic risk in oral surgical procedures. Of these, 203 were scheduled to take place in our department. A total of 180 oral surgical procedures for 147 patients were included. The incidence of bleeding complications in our study was 4.44% (8 out of 180) with a significantly higher risk in patients with haemophilia, the mean time to onset of bleeding was 11 days. DISCUSSION The use of a treatment protocol for the management of patients with inherited bleeding disorders in oral surgery seems effective. Our rate of bleeding complications was comparable to data in the literature, and often lower.

Abstract
BACKGROUND Early identification of bleeding at the scene of an injury is important for triage and timely treatment of injured patients and transport to an appropriate facility. The aim of the study is to compare the performance of different bleeding scores. METHODS We examined data from the Swiss Trauma Registry for the years 2015-2019. The Swiss Trauma Registry includes patients with major trauma (injury severity score (ISS) ≥ 16 and/or abbreviated injury scale (AIS) head ≥ 3) admitted to any level-one trauma centre in Switzerland. We evaluated ABC, TASH and Shock index (SI) scores, used to predict massive transfusion (MT) and the BATT score and used to predict death from bleeding. We evaluated the scores when used prehospital and in-hospital in terms of discrimination (C-Statistic) and calibration (calibration slope). The outcomes were early death within 24 h and the receipt of massive transfusion (≥ 10 Red Blood cells (RBC) units in the first 24 h or ≥ 3 RBC units in the first hour). RESULTS We examined data from 13,222 major trauma patients. There were 1,533 (12%) deaths from any cause, 530 (4%) early deaths within 24 h, and 523 (4%) patients who received a MT (≥ 3 RBC within the first hour). In the prehospital setting, the BATT score had the highest discrimination for early death (C-statistic: 0.86, 95% CI 0.84-0.87) compared to the ABC score (0.63, 95% CI 0.60-0.65) and SI (0.53, 95% CI 0.50-0.56), P < 0.001. At hospital admission, the TASH score had the highest discrimination for MT (0.80, 95% CI 0.78-0.82). The positive likelihood ratio for early death were superior to 5 for BATT, ABC and TASH. The negative likelihood ratio for early death was below 0.1 only for the BATT score. CONCLUSIONS The BATT score accurately estimates the risk of early death with excellent performance, low undertriage, and can be used for prehospital treatment decision-making. Scores predicting MT presented a high undertriage rate. The outcome MT seems not appropriate to stratify the risk of life-threatening bleeding. TRIAL REGISTRATION Clinicaltrials.gov, NCT04561050 .

Abstract
BACKGROUND Reducing maternal and perinatal mortality is a global objective. Hong Kong is a city with low maternal and perinatal mortality but little is known about the trend and causes of these deaths in this high-income city. We analyzed the maternal death, stillbirth and neonatal death since 1946 in Hong Kong. METHODS Data were extracted from vital statistics, based on the number of registered deaths and births, provided by the Department of Health, the Government of the HKSAR. The annual change rate of mortality was evaluated by regression analysis. Contextual factors were collected to assess the association with mortality. FINDINGS Between 1946 and 2017, the stillbirth rate (per 1,000 total births) reduced from 21·5 to 2·4; early and late neonatal deaths (per 1,000 live births) reduced from 14·1 and 18·1 to 0·7 and 0·4 in 2017, respectively. The maternal mortality ratio (per 100,000 live births) declined from 125 to 1·8.The causes of maternal and perinatal deaths were available since 1981 and 1980 respectively. The leading causes of death were thromboembolism (37·0%) and obstetric haemorrhage (30·4%) for maternal death; congenital problem (30·1%) and prematurity (29·0%) for neonatal death. No data on causes of stillbirth were available. No specific shift of pattern was observed in the causes of maternal and neonatal death with time. There were no cases of maternal death due to sepsis and only 2 cases (2·2%) of maternal deaths due to indirect cause. INTERPRETATION The maternal and perinatal death have reduced significantly in Hong Kong and maintained at the lowest level globally. Indirect maternal death and sepsis were unusual causes of maternal deaths. Use of ICD-PM stillbirth classification, setting up a maternal death confidential enquiry and adding pregnancy checkbox could be the next step to identify and categorize hidden burden. FUNDING Nil.

Abstract
PURPOSE Asians have a low venous thromboembolism (VTE) incidence following total knee arthroplasty (TKA). This systematic review and network meta-analysis was conducted to evaluate the best prophylaxis against VTE in Asians following total knee arthroplasty in current literature. MATERIALS AND METHODS A systematic search of PubMed, Embase and CINAHL was conducted in adherence with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Prophylaxis types were separated into low-molecular-weight heparin (LMWH), novel oral anti-coagulants (NOAC), mechanical-only prophylaxis (MOP) and no prophylaxis (NP). The primary outcome was VTE incidence, grouped according to diagnosis modality (ultrasound, venography, clinical). The secondary outcome was bleeding incidence, grouped into minor and major bleeding. RESULTS Fourteen eligible articles, totalling 4259 patients, were pooled with the following significant results: NOACs had lower venography-diagnosed VTE incidence than LMWH (12.77%, p = 0.02) and NP (20.64, p < 0.001). MOP had lower venography-diagnosed VTE incidence than LMWH (23.72%, p < 0.001), NOACs (10.95%, p < 0.001) and NP (31.59%, p < 0.001) but, interestingly, a statistically higher ultrasound-diagnosed VTE incidence than LMWH (6.56%, p = 0.024) and NP (4.88%, p = 0.026). No significant differences were observed between prophylaxis types for symptomatic VTE, pulmonary embolism (PE) or death. LMWH and NOACs had a higher minor bleeding incidence than NP (11.71%, p < 0.001 and 6.33%, p < 0.02, respectively). No significant differences were observed between prophylaxis types for major bleeding incidence. CONCLUSION NOACs are a superior form of chemoprophylaxis, compared with LMWH, in reducing venography-diagnosed VTE incidence with no added bleeding incidence. However, routine chemoprophylaxis may not be required as LMWH and NOACs do not appear to reduce symptomatic VTE incidence compared with MOP and NP with an increased minor bleeding incidence. Mechanical prophylaxis in the form of graduated compression stockings or intermittent pneumatic compression should be routinely considered with significantly lower rates of venography-diagnosed VTE compared with NP. On the basis of current evidence, we recommend an individualised approach to select the most appropriate prophylaxis type.

Abstract
Hyperemesis gravidarum (HG), severe nausea and vomiting in pregnancy, can lead to vitamin deficiencies. Little is known about HG-related vitamin K deficiency. We aimed to summarise available evidence on the occurrence of HG-related vitamin K deficiency and corresponding maternal and neonatal complications. A systematic review was conducted, searching Medline and EMBASE from inception to 12 November 2020. We identified 1564 articles, of which we included fifteen in this study: fourteen case reports (n 21 women) and one retrospective cohort study (n 109 women). Nine out of twenty-one women reported in case reports had a prolonged prothrombin time (PT). The cohort study measured PT in 39/109 women with HG, of whom 10/39 women (26 %) had prolonged PT. In total, 30-50 % women received vitamin K supplementation after vitamin K deficiency had been diagnosed. Four case reports (n 4 women) reported corresponding maternal complications, all consisting of coagulopathy-related haemorrhage. Nine case reports (n 16 neonates) reported corresponding neonatal complications including intracranial haemorrhage (n 2 neonates) and embryopathy (n 14 neonates), which consisted of Binder phenotype (n 14 neonates), chondrodysplasia punctata (n 9 neonates) and grey matter heterotopia (n 3 neonates). In conclusion, vitamin K deficiency and related complications occur among women with HG. In our systematic review, we were unable to assess the incidence rate.

Abstract
BACKGROUND It was not yet fully established whether the use of antiplatelet agents (APAs) is associated with an increased risk of colorectal post-polypectomy bleeding (PPB). Temporarily, discontinuation of APAs could reduce the risk of PPB, but at the same time, it could increase the risk of cardiovascular disease recurrence. This study aimed to assess the PPB risk in patients using APAs compared to patients without APAs or anticoagulant therapy who had undergone colonoscopy with polypectomy. METHODS A systematic electronic search of the literature was performed using PubMed/MEDLINE, Scopus, and CENTRAL, to assess the risk of bleeding in patients who do not interrupt single antiplatelet therapy (P2Y12 inhibitors or aspirin) and undergone colonoscopy with polypectomy. RESULTS Of 2417 identified articles, 8 articles (all of them were non-randomized studies of interventions (NRSI); no randomized controlled trials (RCT) were available on this topic) were selected for the meta-analysis, including 1620 patients on antiplatelet therapy and 13,321 controls. Uninterrupted APAs single therapy was associated with an increased risk of PPB compared to the control group (OR 2.31; CI 1.37-3.91). Patients on P2Y12i single therapy had a higher risk of both immediate (OR 4.43; CI 1.40-14.00) and delayed PPB (OR 10.80; CI 4.63-25.16) compared to the control group, while patients on aspirin single therapy may have a little to no difference increase in the number of both immediate and delayed PPB events. CONCLUSIONS Uninterrupted single antiplatelet therapy may increase the risk of PPB, but the evidence is very uncertain. The risk may be higher in delayed PPB. However, in deciding to discontinue APAs before colonoscopy with polypectomy, the potential higher risk of major adverse cardiovascular events should always be assessed.

Abstract
There is a growing concern nowadays over the exposure of nanomaterials and their effects in aquatic life. In spite of reporting the changes in physiology, reproduction and behaviour in fish by different nanoparticles, the molecular events underlying in the aquatic bodies due to the toxicity of zinc oxide nanoparticles (ZnO NPs) are mainly unexplored. Therefore, the present study carried out an ex vivo exposure of ZnO NPs at various concentrations (0.382, 0.573 and 1.146 mg L-1) in freshwater fish Cyprinus carpio to investigate the potential adverse effects. The results revealed that ZnO NPs exposure altered the haematological parameter and induces the reactive oxygen species (ROS) that leads to elevation of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidise (GPx), glutathione S-transferase (GST) and reduced glutathione (GSH) activity in C. carpio. Furthermore, histopathological analysis exhibited that the ZnO NPs caused lamellar fusion, aneurism, cytoplasmic vacuolation, nuclear alteration, necrotic muscle fiber and pyknotic nuclei in the gills, liver and muscles of C. carpio. ZnO NPs exposure significantly up-regulated the overlapping expressions of SOD1, CAT, GPx1a, GST-α, CYP1A, and Nrf-2 genes. A higher level of Zn bioaccumulation was observed in the following order: gill (35.03 ± 2.50 μg g-1), liver (5.33 ± 0.73 μg g-1) and muscle (2.30 ± 0.20 μg g-1) at 1.146 mg L-1 exposure of ZnO NPs. Hence, the current study indicated that the biogenic ZnO NPs generate toxicity in fishes by modifying the antioxidant defense mechanisms, histomorphology, and oxidative stress encoding genes.

[PMID: 35172841 PMCID: PMC8848629 DOI: 10.1186/s12959-022-00367-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 01/26/2022] [Indexed: 11/15/2022] Open
Abstract
Introduction The summary of product characteristics of vaccines administered intramuscularly, including the vaccine for coronavirus SARS-CoV-2 (COVID-19) and Influenza, warned for risks of bleeding in patients treated with oral anticoagulants. We aimed to estimate the incidence of major bleeding events in this setting and to compare these risks against other vaccination routes. Methods This systematic review included all prospective and retrospective studies enrolling anticoagulated patients that received intramuscular vaccination, published until December 2020 in CENTRAL, MEDLINE and EMBASE. The outcomes of interest were major bleeding and haematoma related with vaccination. The incidence of the outcomes was estimated through a random-effects meta-analysis using the Freeman-Turkey transformation. The results are expressed in percentages, with 95%-confidence intervals (95%CI), limited between 0 and 100%. When studies compared intramuscular vaccination vs. other route, the data were compared and pooled using random-effects meta-analysis. Risk ratios (RR) with 95%CI were reported. Results Overall 16 studies with 642 patients were included. No major bleeding event was reported. The pooled incidence of haematomas following vaccination (mostly against Influenza) in patients treated with oral anticoagulants (mostly warfarin; no data with DOACs / NOACs) was 0.46% (95%CI 0-1.53%). Three studies evaluated the intramuscular vs. subcutaneous route of vaccination. Intramuscular vaccines did not increase the risk of haematoma (RR 0.53, 95%CI 0.10-2.82) compared with subcutaneous route. Conclusions Intramuscular vaccination in anticoagulated patients is safe with very low incidence of haematomas and the best available evidence suggests that using the intramuscular route does not increase the risk of haematomas compared with the subcutaneous route.

Abstract
PURPOSE In the past decade blast injuries have become more prevalent. Blast trauma may cause extensive injuries requiring improved early resuscitation and prevention of haemorrhage. Randomized prospective trials are logistically and ethically challenging, and large animal models are important for further research efforts. Few severe blast trauma models have been described, which is why we aimed to establish a comprehensive polytrauma model in accordance with the criteria of the Berlin definition of polytrauma and with a survival time of > 2 h. Multiple blast injuries to the groin and abdomen were combined with hypoperfusion, respiratory and metabolic acidosis, hypoventilation, hypothermia and inflammatory response. The model was compared to lung contusion and haemorrhage. METHODS 16 landrace swine (mean weight 60.5 kg) were randomized to "control" (n = 5), "chest trauma/hem" by lung contusion and class II haemorrhage (n = 5), and "blast polytrauma" caused by multiple blast injuries to the groin and abdomen, class II haemorrhage, lipopolysaccharide (LPS) infusion and hypothermia 32 °C (n = 6). RESULTS The blast polytrauma group had an Injury Severity Score of 57 which resulted in haemodynamic shock, hypothermia, respiratory and metabolic acidosis and inflammatory response. The chest trauma/hem group had an Injury Severity Score of 9 and less profound physiologic effects. Physiologic parameters presented a dose-response relationship corresponding to the trauma levels. CONCLUSION A comprehensive blast polytrauma model fulfilling the Berlin polytrauma criteria, with a high trauma load and a survival time of > 2 h was established. A severe, but consistent, injury profile was accomplished enabling the addition of experimental interventions in future studies, particularly of immediate resuscitation efforts including whole blood administration, trauma packing and haemostasis.

Abstract
Purpose Severe haemorrhage in percutaneous nephrolithotomy (PCNL) is an alarming event, and preventing injury to renal major vessels is a challenge. We evaluated the efficiency of a blunt needle in renal puncture procedures. Methods We first retrospectively reviewed the embolization images of post-PCNL patients to analyse the types of arteries injured, which were considered target arteries. Then, either a blunt needle or a conventional needle was used to directly puncture target arteries in ex vivo porcine kidneys and to establish renal access ex vivo and in vivo. The primary outcome was the incidence of target artery injuries, which were observed by digital subtraction angiography, nephroscopy and 3-dimensional endocasts. The secondary outcome was the rate of excreted fluid per access. Results The segmental and interlobar arteries were the most common types of injured arteries that needed to be embolized after PCNL. When these arteries were punctured directly, blunt needles reduced injury (1/20 vs. 16/20; OR 4.750; 95% CI 1.966–11.478; P < .001) by 76% compared to injuries induced by conventional needles. Moreover, the blunt needle group also had a significantly lower incidence of these arteries’ injuries ex vivo due to renal puncture and yielded a lower rate of excreted fluid in ex vivo and in vivo renal puncture procedures. Conclusion A blunt needle for renal puncture can be effective in reducing injury to renal major arteries and the accompanying haemorrhage. We propose the concept of blunt puncture, which may be a promising method for achieving safe renal access in PCNL.

Abstract
PURPOSE Tonsillectomies are among the most common surgeries in otorhinolaryngology. A novel electrosurgical temperature-controlled instrument (device) promises rapid tonsillectomies and might reduce postoperative pain, but comparative studies to assess performance are warranted. METHODS This randomized self-controlled clinical trial was conducted from October 2019 to October 2020 at the Department of Otorhinolaryngology, Head and Neck Surgery of the Medical University of Vienna. Forty-eight patients underwent a tonsillectomy with the device on one side and using cold-steel with localized bipolar cauterization on the other side (control). Main outcomes were the time for tonsil removal (per side) and the time to stop bleeding (per side). Secondary measurements were postoperative pain, assessed once on day 0 and five times on days 1, 3, 5, 7, and 10. Postoperative bleeding episodes and consequences were recorded. RESULTS Device tonsillectomies were performed significantly faster than controls; the mean surgical time difference was 209 s (p < 0.001, 95% CI 129; 288). Intraoperative blood loss was significantly lower on the device side (all p < 0.05). Postoperative measurements of pain and bleeding were similar for both sides. Two return-to-theatre secondary bleeding events were recorded for the control side. CONCLUSION The novel electrosurgical temperature-controlled divider reduced the tonsillectomy surgical time and intraoperative blood loss, with no apparent negative effects on postoperative pain or bleeding, compared to a cold-steel tonsillectomy with localized bipolar cauterization. In time-restricted settings, the device could be beneficial, particularly after familiarization with device handling. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03793816.

Abstract
INTRODUCTION Transfusion strategy for trauma patients with massive haemorrhage is often incorporated in massive transfusion protocols (MTP). Albeit correct MTP use results in better patient outcome, research regarding the state of MTP knowledge is scarce. The objective of this study is therefore to assess knowledge of local MTP and massive transfusion strategy in the level 1 trauma centres in the Netherlands. Our hypothesis is that actual MTP knowledge is low and transfusion strategy differs. MATERIALS AND METHODS Surveys were sent out in January 2020 to all trauma and vascular surgeons, anaesthesiologists, emergency department physicians of the largest level 1 trauma centre (locally, n = 113) and to one trauma surgeon, emergency physician and anaesthesiologist in each of the nine other governmentally assigned level 1 trauma centres in the Netherlands (nationally, n = 27). The respondents were subdivided into a frequent user group (MTP usage ≥ 4 times in 2019) and a non-frequent user group (MTP usage < 4 in 2019). Data are expressed as numbers and percentages. RESULTS Response rate was (n = 48; 42%) for the local survey and (n = 14; 52%) for the national survey. Locally, (n = 23; 48%) and (n = 25; 52%) respondents were defined frequent and non-frequent users respectively and national respondents all as frequent users. In total, (n = 13; 27%) of local respondents were aware of the current local composition of the MTP. Respondents indicated to transfuse erythrocytes first, followed by plasma and platelets (local non-frequent users n = 23; 92%, local frequent users n = 21; 91% and national frequent users n = 13; 93%). The indication for platelet transfusion was units erythrocytes transfused (local non-frequent users n = 10; 40% frequent users locally n = 11; 48% and nationally n = 5; 36%) and clinical view (local non-frequent users n = 9; 36%, frequent users locally n = 8; 35% and n<5 nationally. Whereas few respondents claimed (n = 5; 21% non-frequent users locally and n <5 nationally) to transfuse platelets based on platelet counts. Viscoelastic haemostatic assays were performed during MTP, but only by frequent users. CONCLUSION The majority of physicians dealing with massive transfusion in trauma patients were not aware of the exact composition of the MTP and consensus regarding transfusion strategy and indication for platelet transfusion was low.

Abstract
BACKGROUND The incidence of early complications after stoma formation (within 30 days of surgery) is difficult to determine and has been reported to be in a range of 3%-82%. AIM The aim of this study was to analyse the onset of stomal, peristomal and skin complications one month (30 days) after ostomy creation. METHOD This review analysed enteral stoma therapy nurse reports on patients who had an ostomy created between January 2016 and December 2020. FINDINGS Complications were analysed according to ostomy type: colostomy, ileostomy and urostomy. There were 1292 incidences of complications: skin complications were the most common (26%), and abscess the least common (0%). CONCLUSION A majority (63%) of patients experienced at least one or more complications within 30 days of surgery. Haemorrhage was reported as a complication (2%) but the authors found no data on its incidence in the literature. In addition to early complications, late complications were detected.

Abstract
Soft tissue sarcomas containing a dominant component of haemorrhage are known to be aggressive tumours associated with a poor prognosis. Importantly, the clinical behaviour and imaging characteristics of extensively haemorrhagic soft tissue sarcomas (also termed telangiectatic soft tissue sarcomas) can resemble those of benign haematomas, particularly those that continue to expand over a prolonged period, so-called chronic expanding haematomas (CEH). The following review evaluates the current literature to identify the clinical, imaging and pathological characteristics of telangiectatic soft tissue sarcomas and to determine features that may help distinguish them from CEH. Ultimately, we suggest that lesions with sizeable regions of internal haemorrhage should be regarded with a high degree of suspicion for underlying malignancy and require referral to a tertiary sarcoma centre, where a carefully planned approach to biopsy and follow-up is needed to avoid errors in diagnosis.

Abstract
Case summary A 14-year-old male castrated Cornish Rex cat was referred for lethargy progressing rapidly to collapse in the hours following a subcutaneous injection of a product containing 100 mg/ml pentosan polysulfate sodium and 168 mg/ml glucosamine. Physical examination revealed the cat to be in hypotensive shock with swelling and interstitial oedema around the cranial thorax and caudal cervical regions without cutaneous haemorrhage. Initial diagnostics revealed a severe anaemia (packed cell volume 11%) which later deteriorated further, necessitating a blood transfusion and aggressive fluid therapy. Post-transfusion, the patient remained dyspnoeic and subsequent diagnostics found evidence of pre-existing cardiomyopathy and congestive heart failure. The cat was euthanased 24 h following presentation due to increasing dyspnoea. Post-mortem findings were of severe subcutaneous and intermuscular haemorrhage over the neck and thorax, among other changes. There were no detectable levels of coumarin anticoagulants in the liver. Relevance and novel information This is the first reported case of acute subcutaneous and intermuscular haemorrhage of this severity suspected to be related to the off-label use of an injectable product containing pentosan polysulfate in a cat. Given the popularity of its use for feline arthritis, there is a need for large-scale clinical trials to evaluate the safety and efficacy of products containing pentosan polysulfate for cats, and any side effects to be reported.

Abstract
INTRODUCTION Despite considerable advances in the last decade, major adverse events remain a concern after transcatheter aortic valve implantation (TAVI). The aim of this study was to provide a detailed overview of their underlying causes and contributing factors in order to identify key domains for quality improvement. METHODS This observational, prospective registry included all patients undergoing TAVI between 31 December 2015 and 1 January 2020 at the St. Antonius Hospital in Nieuwegein and the University Medical Centre in Utrecht. Outcomes of interest were all-cause mortality, stroke, major bleeding, life-threatening or disabling bleeding, major vascular complications, myocardial infarction, severe acute kidney injury and conduction disturbances requiring permanent pacemaker implantation within 30 days after TAVI, according to the Valve Academic Research Consortium‑2 criteria. RESULTS Of the 1250 patients who underwent TAVI in the evaluated period, 146 (11.7%) developed a major complication. In 54 (4.3%) patients a thromboembolic event occurred, leading to stroke in 36 (2.9%), myocardial infarction in 13 (1.0%) and lower limb ischaemia in 11 (0.9%). Major bleeding occurred in 65 (5.2%) patients, most frequently consisting of acute cardiac tamponade (n = 25; 2.0%) and major access-site bleeding (n = 21; 1.7%). Most complications occurred within 1 day of the procedure. Within 30 days a total of 54 (4.3%) patients died, the cause being directly TAVI-related in 30 (2.4%). Of the patients who died from causes that were not directly TAVI-related, 14 (1.1%) had multiple hospital-acquired complications. CONCLUSION A variety of underlying mechanisms and causes form a wide spectrum of major threats affecting early safety in 11.7% of patients undergoing TAVI in a contemporary cohort of real-world patients.

Abstract
Background Hysterectomy in the peripartum period is a life-saving emergency procedure that is associated with both intra-operative and post-operative morbidities. This study aims to determine the prevalence of emergency obstetric hysterectomy (EOH), the indications, and the pattern of post-emergency obstetric hysterectomy complications and their outcome in our setting. Methodology This was a retrospective study of parturients that had an emergency obstetric hysterectomy (EOH) over a five (5)-year period from 1st January 2008 - 31st December 2012. The case records of these patients were retrieved from the medical record library and information relating to age, parity, booking status, indications, type of hysterectomy, and complications of the procedure were extracted. The data obtained were analysed using the statistical product and service solutions (SPSS) 15.0. Results There were 16,720 deliveries during the five-year period of the study. Emergency obstetric hysterectomies were performed in sixty-nine patients giving a prevalence of 0.4% or 1:242 (4.1 per 1,000) deliveries. Uterine rupture, 33(47.8%) was the leading indication, while the subtotal hysterectomy was the commonest surgery performed 42 (60.9%). The commonest post-hysterectomy morbidities were anaemia, 60 (86.9%) and wound sepsis, 16 (23.2%). Maternal mortality occurred in 7 patients giving a case fatality rate of 10.1%. Conclusions The prevalence of EOH in this study was high with uterine rupture as the leading indication. Wound sepsis and anaemia were the most common post-EOH complications and the case fatality rate was high. Measures must be put in place to prevent uterine rupture and obstetric haemorrhage in our setting.
