文摘Background:Collision medullary and papillary thyroid carcinoma(MTC/PTC)is a rare entity,constituting less than 1%of all thyroid malignancies.The concurrent presence of these malignancies in patients with autoimmune thyroid disease,such as Graves’disease,is even more uncommon.Calcitonin(Ctn)is considered one of the key MTC biomarkers.Mixed tumors may alter this relationship.Case Description:We report the case of a 55-year-old female with a history of Graves’disease,who underwent total thyroidectomy for persistent dysthyroid orbitopathy.Histopathological analysis revealed a 9-mm collision MTC/PTC tumor in the left thyroid lobe,confirmed through immunohistochemical staining.Postoperative evaluation demonstrated lymph node metastases,necessitating central and left lateral neck dissection.Postoperative serum markers(calcitonin,carcinoembryonic antigen,thyroglobulin)declined significantly following surgery and radioiodine therapy.Conclusion:Subcentimeter collision MTC-PTC tumors can be aggressive,challenging size-based management thresholds.Treatment should integrate MTC and PTC protocols,with Ctn,carcinoembryonic antigen(CEA),and thyroglobulin monitored in tandem.Larger datasets are needed to refine Ctn prognostic thresholds in mixed tumors.
文摘BACKGROUND Sorafenib has been the conventional treatment for advanced hepatocellular carcinoma(HCC)since 2008.While radiological complete responses are extremely rare,improved supportive care and multidisciplinary approaches in clinical practice may explain the recent increase in case reports and retrospective series documenting such responses.CASE SUMMARY This case series describes 3 patients with advanced HCC who achieved durable complete responses using first-line sorafenib therapy,even in the presence of portal vein thrombosis or extrahepatic spread,and highlights the potential for sustained remission in selected patients.Dermatologic toxicity and non-viral etiology may correlate with favorable outcomes;however,reliable predictive biomarkers for sorafenib response are lacking.CONCLUSION Future research into the etiology and molecular differences in HCC is necessary to develop more personalized therapy options.
文摘Objective:Artemether is a semi-synthetic derivative of artemisinin and is widely used in the treatment of Plasmodium(P.)falciparum malaria.This study aimed to characterize the safety profile of artemether based on 15-year data retrived from FDA adverse event reporting system(FAERS).Methods:This is a retrospective analysis on 15-year data of artemether-related adverse effects(AEs)retrieved from the FAERS.AEs were classified according to System Organ Class(SOC)and Preferred Terms(PT).Signal detection was performed using Reporting Odds Ratios(ROR),Proportional Reporting Ratios(PRR),and Empirical Bayes Geometric Mean(EBGM).Stratified analyses examined the impact of demographic factors such as sex,age,and time-to-onset.Temporal patterns and associated risk factors were also investigated.Results:Haemolytic anaemia and haemolysis emerged as the most frequently reported AEs,exhibiting significantly elevated RORs(males:ROR 381.36,95%CI 247.06-588.60;females:ROR 455.11,95%CI 286.43-723.12).Sex-specific differences were evident,with females showing a higher incidence of reproductive-related AEs,including spontaneous abortion and premature labour.Temporal trend analysis revealed that the majority of AEs occurred within the first 30 days after the initiation of artemether administration,indicating a rapid onset.The most affected SOCs were blood and lymphatic system disorders and hepatobiliary disorders.Conclusions:Artemether is associated with a notable frequency of early-onset AEs,particularly hematological and hepatobiliary disorders.The observed sex-specific vulnerability to reproductive AEs highlights the need for sex-conscious clinical approaches.Enhanced post-treatment monitoring and further investigations into the drug’s pharmacokinetics and mechanistic pathways are recommended.
文摘BACKGROUND Ankle fractures are well-documented in snow sports,but concomitant Achilles tendon and peroneal tendon ruptures are rare.This case report presents a previously unreported combination of Achilles tendon rupture,peroneal tendon rupture,and fibular fracture in a snowboarder,highlighting the complex nature of diagnosis,management,and rehabilitation.CASE SUMMARY A 50-year-old male snowboarder presented with severe right ankle pain following a high speed tumbling crash.Initial evaluation revealed an Achilles tendon rupture and a non-displaced distal lateral malleolus fracture.Subsequent magnetic resonance imaging confirmed complete tears of the Achilles tendon and both peroneus longus and brevis tendons,along with a Weber A lateral malleolus fracture.Surgical intervention included a 4-suture core Kraków repair of the Achilles tendon with calcaneal docking,open reduction and internal fixation of the distal fibula fracture,and primary repair of both peroneal tendons.Postoperatively,a modified Achilles repair protocol was implemented.At 16 weeks post-surgery,radiographs showed a well-healed fibular fracture,and physical examination confirmed intact Achilles and peroneal tendon repairs.By 6 months,the patient had regained full daily and work activities,including recreational pursuits.CONCLUSION This case underscores the importance of maintaining a high index of suspicion for concomitant injuries in high-energy ankle trauma during snow sports.Timely advanced imaging and a comprehensive surgical approach are crucial for optimal outcomes in such complex cases.
文摘Background:Penile augmentation through injectable substances is becoming increasingly common.A growing number of aesthetic clinics are developing penile enlargement procedures using various injectable materials.Although these procedures are now performed in more controlled and medically supervised environments,their long-term outcomes remain poorly understood.The promotion of such medical treatments contributes to an increasing interest among adult males in self-injection as a method to alleviate psychological distress associated with penile size concerns.At the same time,access to injectable substances through unofficial or unregulated sources has become increasingly easy.Tor our knowledge,we report the first documented case of self-injection with Garamycin®(gentamicin)cream,contributing to the literature on the often multidisciplinary management of penile enlargement injections,a field still lacking well-established guidelines.Case Description:This case report describes a young patient who self-injected Garamycin®into the penis for the purpose of enlargement.He presented to our urology department with worsening symptoms,including severe and poorly tolerated pain.His primary request was prompt relief of pain while preserving,as much as possible,the aesthetic appearance and functional integrity of his penis.This case required a multi-stage surgical approach to salvage the penis and preserve both its structural integrity and functional outcome.Conclusions:To our knowledge,this case report documents the first reported instance of Garamycin®injection performed for the purpose of penile enlargement.It provides insight into the clinical course of such penile cream injections,demonstrates that a two-stage scrotal flap can achieve both functional and aesthetic outcomes,and highlights the importance of comprehensive management particularly addressing the traumatic impact of penile deformity secondary to inflammation and/or infection,as well as the body dysmorphic concerns often associated with these cases.
文摘BACKGROUND SMARCB1/INI1-deficient pancreatic undifferentiated rhabdoid carcinoma is a highly aggressive tumor,and spontaneous splenic rupture(SSR)as its presenting manifestation is rarely reported among pancreatic malignancies.CASE SUMMARY We herein report a rare case of a 59-year-old female who presented with acute left upper quadrant abdominal pain without any history of trauma.Abdominal imaging demonstrated a heterogeneous splenic lesion with hemoperitoneum,raising clinical suspicion of SSR.Emergency laparotomy revealed a pancreatic tumor invading the spleen and left kidney,with associated splenic rupture and dense adhesions,necessitating en bloc resection of the distal pancreas,spleen,and left kidney.Histopathology revealed a biphasic malignancy composed of moderately differentiated pancreatic ductal adenocarcinoma and an undifferentiated carcinoma with rhabdoid morphology and loss of SMARCB1 expression.Immunohistochemical analysis confirmed complete loss of SMARCB1/INI1 in the undifferentiated component,along with a high Ki-67 index(approximately 80%)and CD10 positivity.The ductal adenocarcinoma component retained SMARCB1/INI1 expression and was positive for CK7 and CK-pan.Transitional zones between the two tumor components suggested progressive dedifferentiation and underlying genomic instability.The patient received adjuvant chemotherapy with gemcitabine and nab-paclitaxel and maintained a satisfactory quality of life at the 6-month follow-up.CONCLUSION This study reports a rare case of SMARCB1/INI1-deficient undifferentiated rhabdoid carcinoma of the pancreas combined with ductal adenocarcinoma,presenting as SSR-an exceptionally uncommon initial manifestation of pancreatic malignancy.
文摘BACKGROUND Salvage of the infected long stem revision total knee arthroplasty is challenging due to the presence of well-fixed ingrown or cemented stems.Reconstructive options are limited.Above knee amputation(AKA)is often recommended.We present a surgical technique that was successfully used on four such patients to convert them to a knee fusion(KF)using a cephalomedullary nail.CASE SUMMARY Four patients with infected long stem revision knee replacements that refused AKA had a single stage removal of their infected revision total knee followed by a KF.They were all treated with a statically locked antegrade cephalomedullary fusion nail,augmented with antibiotic impregnated bone cement.All patients had successful limb salvage and were ambulatory with assistive devices at the time of last follow-up.All were infection free at an average follow-up of 25.5 months(range 16-31).CONCLUSION Single stage cephalomedullary nailing can result in a successful KF in patients with infected long stem revision total knees.

文摘Background:In clinical practice,approximately 80%of prostate cancer(PC)cases are localized and can achieve favorable outcomes with appropriate treatment.Conversely,some remaining cases exhibit an aggressive phenotype or develop resistance to therapeutic interventions,leading to tumor metastasis and a poorer prognosis.When PC metastasizes to distant sites,the bone remains the predominant location,and brain metastases are regarded as exceedingly rare.Case Description:The current study focused on a rare clinical PC case that presented multiple brain metastases after prostate surgery.The patient was initially diagnosed with PC through prostate biopsy and subsequently underwent prostate debulking surgery while continuing androgen deprivation therapy,which maintained low prostatespecific antigen(PSA)levels for 4 years.However,a sudden PSA surge to 7.858 ng/mL led to the emergence of two brain metastatic tumors,which were confirmed to have originated from the prostate.Conclusions:Patients with advanced PC require comprehensive evaluations to detect rare metastatic sites,such as the brain,to avoid missed diagnoses.For patients with brain metastases,a multimodal approach combining surgical resection,postoperative radiotherapy,and endocrine therapy can effectively alleviate symptoms and enhance survival.
文摘BACKGROUND Well-differentiated small bowel mesenteric liposarcoma(LPS)is rare,with high malignancy,poor prognosis,and high preponderance to local recurrence.CASE SUMMARY Here we described a 71-year-old male,who complains of persistent abdominal distension for a month.The clinical manifestation is a huge abdominal mass occupying almost the entire abdomen.Physical examination indicated palpable massive mass in the abdomen,hard texture,indefinable boundary,poor mobility.The abdominal enhanced computed tomography at another hospital scan showed multiple abdominal masses originating from the small bowel mesentery.Abdominal and pelvic magnetic resonance imaging at our hospital showed multiple masses in the abdominal and pelvic cavities,indicating that the tumor originated from the mesentery or peritoneum.Results of exploratory laparotomy indicated that the tremendous mass primarily results from the mesentery of the small intestine,occupying the entire abdominal cavity in a polymorphic and lobulated shape.The patient underwent complete surgical resection of the tumor,and the weight of the tumor was approximately 11 kg.The histopathological examination of the resected specimens confirmed the diagnosis of well-differentiated LPS of the small bowel mesentery.CONCLUSION Completed surgical resection was cornerstone,and histopathological and molecular confirmations were crucial.The necessity of adjuvant therapy should be phrased as a potential consideration to improve patient’s survival time.

文摘Online Public Opinion Reports consolidate news and social media for timely crisis management by governments and enterprises.While large language models(LLMs)enable automated report generation,this specific domain lacks formal task definitions and corresponding benchmarks.To bridge this gap,we define the Automated Online Public Opinion Report Generation(OPOR-Gen)task and construct OPOR-Bench,an event-centric dataset with 463 crisis events across 108 countries(comprising 8.8 K news articles and 185 K tweets).To evaluate report quality,we propose OPOR-Eval,a novel agent-based framework that simulates human expert evaluation.Validation experiments show OPOR-Eval achieves a high Spearman’s correlation(ρ=0.70)with human judgments,though challenges in temporal reasoning persist.This work establishes an initial foundation for advancing automated public opinion reporting research.
文摘BACKGROUND Hepatocellular carcinoma(HCC)is a major type of liver cancer worldwide.In advanced stages,portal vein tumor thrombosis(PVTT)and jaundice are common,whereas obstructive jaundice(OJ)is relatively rare.Both conditions markedly reduce survival and increase therapeutic complexity.Recently,hepatic artery infusion chemotherapy(HAIC)in combination with targeted immunotherapy has shown promise for advanced HCC.CASE SUMMARY We report a 47-year-old male with advanced HCC complicated by PVTT and OJ,who was admitted with marked jaundice of the skin and sclera.Imaging revealed a large hepatic mass(14.5 cm×11.3 cm)in the right lobe with associated portal vein tumor thrombus.The tertiary bile duct was only mildly dilated,making percutaneous transhepatic cholangiography drainage infeasible.The patient underwent reduced-dose HAIC,which resulted in significant tumor shrinkage and marked reduction in serum bilirubin.This improvement enabled sequential treatment with lenvatinib and camrelizumab.After six cycles,both liver function and alphafetoprotein levels improved.The patient achieved a progression-free survival of 20 months and an overall survival of 29 months.CONCLUSION HAIC can treat high-bilirubin HCC with PVTT and OJ,allowing for subsequent targeted immunotherapy.
文摘BACKGROUND While varices and variceal bleeds are well-known and feared complications of advanced cirrhosis and portal hypertension,omental variceal bleed are a rare sequala even in patients with known esophageal or gastric varices.While rare,omental varices pose a risk for hemoperitoneum if ruptured,which is a lifethreatening complication with high mortality rates despite surgical intervention.CASE SUMMARY This report reviews the case of a patient 36-year-old female with alcohol related cirrhosis decompensated by ascites,but no history of varices admitted for hemorrhagic shock from spontaneous rupture of omental varices requiring emergency surgery.She underwent the first documented successful orthotopic liver transplantation the same admission.CONCLUSION This case report and literature review stresses the importance of early consideration and identification of intraabdominal variceal sources in cirrhotic patients with refractory shock.
文摘It is challenging to diagnose isolated hyperbilirubinemia with rare and complex etiologies under the constraints of traditional testing conditions.Herein,we present a rare case of coexisting Gilbert syndrome(GS)and erythropoietic protoporphyria(EPP),which has not been previously documented.CASE SUMMARY We present a rare case of coexisting GS and EPP in a 23-year-old Chinese male with a long history of jaundice and recently found splenomegaly.Serial nonspecific hemolysis screening tests yielded inconsistent results,and investigations for common hemolytic etiologies were negative.However,Levitt’s carbon monoxide breath test,which measures erythrocyte lifespan(the gold-standard marker of hemolysis),demonstrated significant hemolysis,revealing a markedly shortened erythrocyte lifespan of 11 days(normal average 120 days).Genetic testing subsequently confirmed EPP with a homozygous ferrochelatase gene mutation and GS with a heterozygous uridine diphosphate glucuronosyl trans-ferase 1A1 gene mutation.CONCLUSION The rapid,non-invasive Levitt’s carbon monoxide breath test resolved the diagnostic challenge posed by a rare and complex cause of hyperbilirubinemia.
文摘BACKGROUND With the increasing use of laparoscopic techniques in living-donor kidney transplantation,limitations in donor vessel length,particularly of the right renal vein,pose significant challenges for vascular anastomosis to the recipient’s external iliac vein.These anatomical constraints can complicate graft implantation and increase the risk of postoperative complications.CASE SUMMARY To address the issue of short right renal veins,several surgical strategies have been proposed.In this report,we describe our experience with three cases in which venous extension was successfully achieved using a venous cuff interposition technique during back-table reconstruction.This approach was used to facilitate secure vascular anastomosis and improve graft positioning in anatomically complex transplant scenarios.CONCLUSION Venous cuff interposition represents an effective technique for managing short renal veins in living-donor kidney transplantation.It provides additional length and flexibility,easing anastomotic tension and supporting successful transplantation.
文摘BACKGROUND Ulcerative colitis(UC)is a chronic and debilitating inflammatory bowel disease.Cumulative evidence indicates that excess hydrogen peroxide,a potent neutrophilic chemotactic agent,produced by colonic epithelial cells has a causal role leading to infiltration of neutrophils into the colonic mucosa and subsequent development of UC.This evidence-based mechanism identifies hydrogen peroxide as a therapeutic target for reducing agents in the treatment of UC.CASE SUMMARY Presented is a 41-year-old female with a 26-year history of refractory UC.Having developed steroid dependence and never achieving complete remission on treatment by conventional and advanced therapies,she began treatment with oral R-dihydrolipoic acid(RDLA),a lipid-soluble reducing agent with intracellular site of action.Within a week,rectal bleeding ceased.She was asymptomatic for three years until a highly stressful experience,when she noticed blood in her stool.RDLA was discontinued,and she began treatment with oral sodium thiosulfate pentahydrate(STS),a reducing agent with extracellular site of action.After a week,rectal bleeding ceased,and she resumed oral RDLA and discontinued STS.To date,she remains asymptomatic with normal stool calprotectin while on RDLA.CONCLUSION STS and RDLA are reducing agents that serve as highly effective and safe therapy for the induction and maintenance of remission in UC,even in patients refractory or poorly controlled by conventional and advanced therapies.Should preliminary findings be validated by subsequent clinical trials,the use of reducing agents could potentially prevent thousands of colectomies and represent a paradigm shift in the treatment of UC.
文摘BACKGROUND Early renal artery thrombosis after kidney transplantation is rare but often leads to graft loss.Prompt diagnosis and intervention are essential,particularly in patients with inherited thrombophilias such as factor V Leiden(FVL)mutation.CASE SUMMARY A kidney transplant recipient with FVL mutation developed an acute transplant renal artery thrombosis.The immediate post-operative Doppler ultrasonography revealed thrombosis of the main and inferior polar renal arteries.Emergent thrombectomy and separate arterial re-anastomoses were performed after cold perfusion with heparinized saline and vasodilator solution.Reperfusion was successful with immediate urine output and gradual improvement in renal function.The patient was discharged on direct oral anticoagulation therapy.CONCLUSION Early detection and surgical intervention can preserve graft function in posttransplant renal artery thrombosis even in patients at high risk.
