Wang et al identifiedseveral significant risk factors of SSIs, including age ≥ 60 years, diabetesmellitus, and surgical complications such as insufficient cystic duct stump closure,gallbladder perforation, empyema, and postoperative hematoma. Their findingssuggest that prophylactic antibiotics can serve as a protective factor against SSIs.However, other reported risk factors and preventive strategies warrant considerationto further reduce the incidence of SSIs, lower healthcare costs, and enhancepatient outcomes. Additionally, the judicious use of prophylactic antibioticsis crucial in light of the growing global challenge of antibiotic resistance caused bythe misuse and overuse of antibiotics. Effective management strategies forprophylactic antibiotic use should be prioritized to balance infection control withthe need to combat antimicrobial resistance.展开更多

文摘Middle meningeal artery embolization(MMAE)has revolutionized chronic subdural hematoma management,yet procedural risks persist due to anatomical variability.We analyze a case report by Zhao et al describing transient diplopia caused by inadvertent embolization of the lacrimal artery via a dynamic middle meningeal–ophthalmic anastomosis.This correspondence advances three critical innovations in MMAE safety.First,intraoperative anastomotic unmasking—exposing occult middle meningeal-ophthalmic collaterals during particle injection—reveals dynamic vascular behavior missed by preoperative angiography,underscoring the need for adaptive imaging protocols.Second,hybrid embolization(liquid agents for proximal occlusion+particles for distal control)balances precision and safety,reducing reflux risks compared to monotherapy.Third,a 108-day follow-up establishes a benchmark for functional recovery,challenging assumptions about irreversible cranial nerve injuries and emphasizing structured postprocedural care.Collectively,these findings advocate for procedural agility,multimodal embolic strategies,and sustained rehabilitation to optimize MMAE outcomes while minimizing iatrogenic harm.
文摘The Kakinuma et al’s case report shows that non-pregnancy-related arterial pseudoaneurysm is a relatively rare,little known by some gynecologists,endo-scopists,surgeons or radiologists,which can cause massive bleeding.Arterial pseudoaneurysm is a condition in which the wall of a blood vessel collapses due to some invasive event,and the resulting leaked blood is engulfed by soft tissues,forming a cavity that is in communication with the vessel.It is a potentially life-threatening complication that could occurs after some deliveries and some gynecological invasive procedures.Remarkably,an undetermined percentage of pseudoaneurysms are asymptomatic,and in an asymptomatic patient it is difficult to predict the risk of haemorrhage and the attitude to follow,which depends on several factors,such as,the size and location of the vessel involved,changes in the size of the pseudoaneurysm,or the available therapeutic resources to be offered to patients,among others circumstances.The management of abdominal arterial pseudoaneurysm does not have consistent scientific evidence,but it seems that,regardless of the associated circumstances,the pseudoaneurysm could be treated at least initially,and mainly,through endovascular procedures,as done by Kakinuma et al.
文摘Portal vein embolization(PVE)is currently considered the standard of care to improve the volume of an inadequate future remnant liver(FRL)and decrease the risk of post-hepatectomy liver failure(PHLF).PHLF remains a significant limitation in performing major liver surgery and is the main cause of mortality after resection.The degree of hypertrophy obtained after PVE is variable and depends on multiple factors.Up to 20%of patients fail to undergo the planned surgery because of either an inadequate FRL growth or tumor progression after the PVE procedure(usually 6-8 wk are needed before surgery).The management of PVE failure is still debated,with a lack of consensus regarding the best clinical strategy.Different additional techniques have been proposed,such as sequential transarterial chemoembolization followed by PVE,segment 4 PVE,intra-portal administration of stem cells,dietary supplementation,and hepatic vein embolization.The aim of this review is to summarize the up-to-date strategies to overcome such difficult situations and discuss future perspectives on improving FRL hypertrophy.
文摘BACKGROUND Middle meningeal artery embolization(MMAE)is emerging as a promising treatment for chronic subdural hematoma(CSDH),serving both as an adjunct to surgery and as a primary therapeutic option depending on patient presentation.Due to its low recurrence rate and minimal complications,MMAE has gained increasing acceptance among clinicians in recent years.This report presents a case of diplopia following MMAE due to the presence of a potential anastomotic artery,aiming to enhance awareness of this complication.CASE SUMMARY A 60-year-old male patient presented with a headache following head trauma,and cranial computed tomography revealed a left-sided CSDH.The patient underwent left MMAE;however,polyvinyl alcohol particles inadvertently flowed into the lacrimal artery through an anastomotic artery,resulting in diplopia due to impaired abduction of the left eye.The diplopia resolved by postoperative day 40.The patient’s headache resolved by postoperative day 7,and the hematoma completely resolved by postoperative day 108.CONCLUSION Potential anastomotic arteries in the middle meningeal artery(MMA)can lead to serious complications.Superselective angiography of the MMA or its branches prior to embolization is essential.Performing embolization distal to potential anastomotic sites can reduce risks,and the presence of an anastomosis may warrant coil embolization or termination of the procedure.
文摘BACKGROUND Acute respiratory infections(ARI)and diarrhoea are among the leading causes of infant and under-five mortality worldwide.Zinc,the second most abundant trace element in the human body,is widely used in the treatment of both conditions.It mitigates diarrhoea by restoring mucosal integrity and enhancing enterocyte brush border enzyme activity.In ARI,zinc boosts immune function,promotes epithelial regeneration,and inhibits the replication of respiratory viruses.AIM To assess the effectiveness of prophylactic intermittent zinc supplementation in preventing acute diarrhoea and ARI in infants.METHODS This open-label,randomized controlled trial with a 1:1 allocation ratio was conducted over 15 months(October 2022 to December 2023)at a tertiary care hospital in Eastern India.A total of 320 infants attending the outpatient department for routine vaccinations were enrolled and randomly assigned to intervention and control groups.The intervention group received zinc drops for two weeks,with the regimen repeated one month later and again at six months during subsequent vaccination visits.The control group received no placebo or alternative treatment.Outcomes were assessed after the final follow-up at nine months.RESULTS The mean annual incidence of ARI and diarrhoea was significantly lower in the zinc group than in the control group[ARI:0.25±0.61 vs 0.92±1.22;mean difference=-0.67(95%CI:-0.88 to-0.45),P<0.001,Cohen’s d=-0.69]and[diarrhoea:1.04±1.30 vs 2.07±2.09;mean difference=-1.03(95%CI:-1.42 to-0.65),P<0.001,Cohen's d=-0.59],respectively.Additionally,the zinc group showed significantly greater gains in length[10±0.6 cm vs 8.6±0.4 cm;mean difference=1.4(95%CI:1.3-1.5),P<0.001,Cohen’s d=2.74]and weight[3150±108 g vs 2818±76 g;mean difference=332(95%CI:310-352),P<0.001,Cohen's d=3.56].CONCLUSION Prophylactic intermittent zinc supplementation administered alongside routine immunization substantially reduces the incidence of ARI and diarrhoea in infants and promotes improved growth.This affordable strategy holds promise for reducing infant morbidity and mortality without increasing healthcare burdens.

文摘In this article, we have addressed the recent published article by Wang et al whichexamines risk factors associated with surgical site infections (SSIs) and evaluatesthe effectiveness of prophylactic antibiotics in their prevention. Wang et al identifiedseveral significant risk factors of SSIs, including age ≥ 60 years, diabetesmellitus, and surgical complications such as insufficient cystic duct stump closure,gallbladder perforation, empyema, and postoperative hematoma. Their findingssuggest that prophylactic antibiotics can serve as a protective factor against SSIs.However, other reported risk factors and preventive strategies warrant considerationto further reduce the incidence of SSIs, lower healthcare costs, and enhancepatient outcomes. Additionally, the judicious use of prophylactic antibioticsis crucial in light of the growing global challenge of antibiotic resistance caused bythe misuse and overuse of antibiotics. Effective management strategies forprophylactic antibiotic use should be prioritized to balance infection control withthe need to combat antimicrobial resistance.
文摘Objective:To analyze the value of prophylactic antibiotic use in reducing the incidence of pancreatic necrosis in patients with emergency acute pancreatitis(AP).Methods:A total of 70 AP patients who sought medical attention from January 2024 to January 2025 were randomly divided into groups by drawing lots.Group A received prophylactic antibiotic intervention,while Group B received conventional intervention.Results:Group A demonstrated superior outcomes compared to Group B in terms of therapeutic efficacy,duration of symptoms,inflammatory factors,symptom scores,and complication rates,with p<0.05.Conclusion:Prophylactic antibiotic treatment in emergency AP patients leads to a decrease in inflammatory factor levels,alleviation of symptoms,a reduction in the incidence of infectious pancreatic necrosis,and is safe and effective.
文摘BACKGROUND Surgical site infections(SSIs)are a significant complication in laparoscopic cholecystectomy(LC),affecting patient outcomes and healthcare costs.AIM To identify risk factors associated with SSIs and evaluate the effectiveness of prophylactic antibiotics in reducing these infections.METHODS A comprehensive retrospective evaluation was conducted on 400 patients who underwent LC from January 2022 to January 2024.Patients were divided into infected(n=36)and non-infected(n=364)groups based on the occurrence of SSIs.Data collected included age,diabetes mellitus status,use of prophylactic antibiotics,and specific surgical complications.Statistical analyses using SPSS(Version 27.0)involved univariate and multivariate logistic regression to determine factors influencing the risk of SSIs.RESULTS The use of prophylactic antibiotics significantly reduced the incidence of SSIs(χ²=68.34,P<0.01).Older age(≥60 years)and comorbidities such as diabetes mellitus were identified as significant risk factors.Surgical complications like insufficient cystic duct stump,gallbladder perforation,and empyema also increased SSI risk.Notably,factors such as intraoperative blood loss and operation time did not significantly impact SSI occurrence.CONCLUSION Prophylactic antibiotics are effective in reducing the risk of SSIs in patients undergoing LC.Age,diabetes mellitus,and certain surgical complications significantly contribute to the risk.Effective management of these risk factors is essential to improve surgical outcomes and reduce the incidence of SSIs.
文摘Transarterial chemoembolization(TACE)is the first line treatment for patients with intermediate stage hepatocellular carcinoma but is also increasingly being used for patients on the transplant waiting list to prevent further tumor growth.Despite its widespread use,TACE remains an unstandardized procedure,with variation in type and size of embolizing particles,type and dose of chemotherapy and interval between therapies.Existing evidence from randomized controlled trials suggest that bland transarterial embolization(TAE)has the same efficacy with TACE.In the current article,we review the use of TACE and TAE for hepatocellular carcinoma and we focus on the evidence for their use.
文摘Inappropriate use of antibiotics leads to microbial resistance.Single-dose antibio-tic prophylaxis prior to laparoscopic cholecystectomy is well known for reducing the risk of postoperative infection in high-risk patients despite some conflicting aspects.High-risk patients are those who are older than 70 years,have diabetes mellitus,whose operation time exceeded 120 minutes,have acute cholecystitis,experienced iatrogenic intraoperative gallbladder perforation resulting in bile or gallstone spillage,suffered from obstructive jaundice,or were deemed immuno-compromised.For gallbladder perforation,one dose of antibiotic prophylaxis is sufficient.Therefore,guidelines are needed and must be strictly followed.Prophy-lactic treatment is not needed for patients at low risk of developing sepsis fo-llowing elective laparoscopic cholecystectomy,although the opposite is suppor-ted.Similarly,superficial surgical infections are related to low morbidity.Patients without risk factors have a very low risk of infection.Thus,the routine use of anti-biotic prophylaxis in elective laparoscopic cholecystectomy is not recommended.

文摘BACKGROUND Acute cholecystitis due to unintended cystic artery embolism is an uncommon and mostly self-limiting complication after transarterial chemoembolization procedure for treatment of hepatocellular carcinoma.Usually,conservative management is sufficient for complete recovery of patients who develop this complication.If conservative treatment is ineffective,urgent surgical inter-vention may be required to prevent the progression of complications.CASE SUMMARY This article reports a rare and serious case of acute cholecystitis complicated by gallbladder necrosis and biliary peritonitis,which was initially treated conservatively but eventually necessitated emergency laparotomy.The patient initially presented with equivocal symptoms of fever and upper abdominal pain and distention,which worsened at the two weeks mark along with emergence of signs of peritonitis.This was managed by emergency laparotomy and cholecystostomy,allowing rapid symptom relief.The patient ultimately discharged and succumbed to advanced liver cancer 11 months after diagnosis.CONCLUSION After cholecystostomy,the patient showed symptom relief and was discharged,surviving 11 months post-stage IIIB liver cancer diagnosis.
文摘Prophylactic fixation(ProFix)of the proximal femur in elderly patients with osteoporosis presents a forward-thinking approach to preventing debilitating fractures and their associated complications.By addressing fracture risk before an injury occurs,ProFix has the potential to enhance patient outcomes,promote long-term mobility,and reduce healthcare costs.Early intervention in individuals at high risk can significantly lower hospital admissions,shorten recovery periods,and preserve independence,mitigating challenges such as chronic pain and reduced life expectancy.Given the high prevalence of undiagnosed osteoporosis,prioritising early risk assessment and targeted prevention is essential.Advancements in minimally invasive surgical techniques and safer anaesthesia methods further support ProFix as a feasible and effective strategy to decrease fracturerelated morbidity,improve overall patient well-being,and optimise the use of healthcare resources.This opinion review details the evidence supporting this concept,its efficacy,the challenges in its implementation,and a strategic plan for future implementation.

文摘Transcatheter arterial embolization(TAE)is the mainstay for treating advanced hepatocellular carcinoma(HCC),and the performance of the embolization material is crucial in TAE.With the development of medical imaging and the birth of“X-ray-free”technologies,we designed a new dual-mode imaging material of dimethoxy tetraphenyl ethylene(DMTPE)via emulsification by mixing poly(N-isopropylacrylamide-co-acrylic acid)(PNA)with lipiodol and fluorocarbons,which was evaluated for temperature sensitivity,stability,and dual-mode visualization in vitro.Additionally,blood vessel casting embolization and renal artery imaging were assessed in healthy rabbits.In a rabbit model with a VX2 tumor,the effectiveness of TAE for treating HCC was examined,with an emphasis on evaluating long-term outcomes of embolization and its effects on tumor growth,necrosis,and proliferation through imaging techniques.In vitro experiments confirmed that the temperature-sensitive dual-oil-phase Pickering emulsion had good flow,stable contrast,and embolism when the oil-to-oil ratio and water-to-oil ratio were both 7:3(v/v)and stabilized with 8%PNA.Similarly,in vivo,arterial embolization confirmed the excellent properties of DMTPE prepared at the abovementioned ratios.It was observed that DMTPE not only has an antitumor effect but can also achieve dual imaging using X-rays and ultrasound,making it a promising excellent vascular embolization material for TAE in tumor treatment.

文摘Fear memory,a predictive and protective mechanism in potentially hostile environments,elicits defensive behavioral responses that have evolved to help organisms avoid harm and ensure survival.However,excessive fear memories may contribute to the onset of various psychological disorders,such as panic disorder,phobias,and post-traumatic stress disorder(PTSD).
文摘Endoscopic ultrasound(EUS)guided vascular interventions have expanded the reach of therapeutic endoscopy to include vascular pathology previously inaccessible by endoscopists.Gastric variceal bleeding comprises 20%of all variceal bleeding and is associated with high morbidity and mortality.Historically,endoscopic injection of thrombosis-inducing agents such as glue has been used.However,glue injection carries potential risks including systemic embolization,damage to the endoscope,and recurrent bleeding.The introduction of hemostatic coils has revolutionized the endoscopic approach,with EUS-guided coil embolization emerging as an effective and safe modality for the management of gastric varices(GVs).When compared with conventional glue injection,EUSguided embolization is associated with improved visualization,higher efficacy,and better safety profile.Despite its expanding adoption,the standardization of EUS guided embolization remains a challenge.High-quality studies are needed to standardize this promising technique and define its role in clinical practice.In this review,we will discuss the indications,efficacy,techniques,and various approaches for EUS-guided embolization of GVs.
文摘Traumatic carotid-cavernous arteriovenous fistula(TCCAVF)is a rare but severe cerebrovascular disorder,often resulting from head trauma with temporal bone fractures.The pathogenesis involves vessel wall injury due to traction,frequently associated with fractures near the middle meningeal artery.This case highlights the typical clinical presentation,diagnostic approaches,and therapeutic management of TCCAVF,emphasizing the challenges in treating this condition.Transcatheter embolization proved effective in occluding the fistula,underscoring its role as a key intervention for traumatic meningeal arteriovenous fistulas.
文摘BACKGROUND Post-operative infection is a common and serious complication following drugeluting trans arterial chemo embolization(D-TACE)in patients with hepatocellular carcinoma(HCC),potentially compromising treatment efficacy and increasing morbidity.AIM To investigate the risk factors associated with post-operative infection in HCC patients undergoing D-TACE,and to provide evidence for clinical prevention and targeted intervention strategies.METHODS Clinical data of 77 primary HCC patients who underwent D-TACE in our hospital from January 2022 to December 2023 were retrospectively analyzed.Patient demographics,laboratory test results,tumor characteristics,and surgery-related parameters were collected.Univariate and multivariate logistic regression analyses were performed to identify risk factors for post-operative infection.RESULTS Post-operative infection occurred in 20 cases(25.97%)among the 77 patients.Univariate analysis showed that age≥65 years,Child-Pugh grade B,tumor diameter≥5 cm,operation time≥120 minutes,preoperative albumin<35 g/L,and comorbid diabetes were significantly associated with post-operative infection(P<0.05).Multivariate logistic regression analysis identified Child-Pugh grade B(OR=2.851,95%CI:1.426-5.698),operation time≥120 minutes(OR=2.367,95%CI:1.238-4.523),and preoperative albumin<35 g/L(OR=2.156,95%CI:1.147-4.052)as independent risk factors for post-operative infection.CONCLUSION Liver function status,operation time,and preoperative albumin level are significant factors affecting post-operative infection in HCC patients undergoing D-TACE.For high-risk patients,enhanced perioperative management,appropriate timing of surgery,and active improvement of nutritional status should be implemented to reduce the risk of post-operative infection.
