Implement Constitutional Principles to Uncover Tort Cases——An interview with Wang Zhenchuan, deputy chief procurator of the Supreme People's Procuratorate

EDITOR'S NOTE: Since May 2004, the people's procuratorates in China have concentrated their efforts on uncovering cases of encroaching upon human rights by government functionaries by abusing their power. The move has aroused extensive attention. On this, our staff reporter interviewed Deputy Chief Procurator Wang Zhenchuan, who is in charge of the campaign against human rights violations.

Effectiveness of lorazepam-assisted interviews in an adolescent with dissociative amnesia A case report

To facilitate gathering information during a psychiatric interview, some psychiatrists advocate augmenting the interview using drugs. Rather than barbiturates, benzodiazepines have been used for drug-assisted interviews. Dissociative amnesia is one of the indications for these interviews. Herein, we present the case of a 15-year-old female who was diagnosed as having dissociative amnesia because of conflicts with her friends. She was administered a Iorazepam-assisted interview to aid recovery of her memories. In this case, a small dose of Iorazepam was sufficient to recover her memories without any adverse effects.

The Interpretation of the Choice of Deixis in Teacher's Speech—A Case Study in a Thesis Defense Interview

It is known to all that distinct choices of deixis can reflect various meanings underlying the surface level. In addition to conveying a specific reference and inference, it can reflect the people's mental activities. From the perspective of psychological distance, this thesis tends to interpret the connotation underlying the the deixis chosen by those teachers in a thesis defense interview so as to help them better understand their self-identity and psychological. Besides, through this study, the students, who attend the thesis defense interview, are able to improve their capability dealing with those teachers' questions.

Are case reports valuable?Exploring their role in evidence based medicine and patient care

Case reports,often overlooked in evidence-based medicine(EBM),play a pivotal role in healthcare research.They provide unique insights into rare conditions,novel treatments,and adverse effects,serving as valuable educational tools and generating new hypothesis.Despite their limitations in generalizability,case reports contribute significantly to evidence-based practice by offering detailed clinical information and fostering critical thinking among healthcare professionals.By acknowledging their limitations and adhering to reporting guidelines,case reports can contribute significantly to medical knowledge and patient care within the evolving landscape of EBM.This editorial explores the intrinsic value of case reports in EBM and patient care.

Using clinical cases to guide healthcare

Evidence-based practice(EBP)has been the gold standard in healthcare for nearly three centuries and aims to assist physicians in providing the safest and most effective healthcare for their patients.The well-established hierarchy of evidence lists systematic reviews and meta-analyses at the top however these methodologies are not always appropriate or possible and in these instances case-control studies,case series and case reports are utilised to support EBP.Case-control studies allow simultaneous study of multiple risk factors and can be performed rapidly and relatively cheaply.A recent example was during the Coronavirus pandemic where case-control studies were used to assess the efficacy of personal protective equipment for healthcare workers.Case series and case reports also play a role in EBP and are particularly useful to study rare diseases such as inflammatory bowel disease in transgender and gender non-conforming individuals.They are also vital in generating and disseminating early signals and encouraging further research.Whilst these methodologies have weaknesses,particularly with regards to bias and loss of patient confidentiality for rare pathologies,they have an important part to play in EBP and when appropriately utilised can significantly impact upon clinical practice.

Metastatic clear cell sarcoma of the pancreas:A rare case report

BACKGROUND Clear cell sarcoma(CCS)is a rare soft-tissue sarcoma.The most common metastatic sites for CCS are the lungs,bones and brain.CCS is highly invasive and mainly metastasizes to the lung,followed by the bone and brain;however,pancreatic metastasis is relatively rare.CASE SUMMARY We report on a rare case of CCS with pancreatic metastasis in a 47-year-old man.The patient had a relevant medical history 3 years ago,with abdominal pain as the main clinical manifestation.No abnormalities were observed on physical examination and the tumor was found on abdominal computed tomography.Based on the medical history and postoperative pathology,the patient was diagnosed with CCS with pancreatic metastasis.The patient was successfully treated with surgical interventions,including distal pancreatectomy and sple-nectomy.CONCLUSION This report summarizes the available treatment modalities for CCS and the importance of regular postoperative follow-up for patients with CCS.

Primary gastroduodenal tuberculosis presenting as gastric outlet obstruction:A case report and review of literature

BACKGROUND Mycobacterium tuberculosis(TB)is the causative agent of TB,a chronic granulo-matous illness.This disease is prevalent in low-income countries,posing a significant global health challenge.Gastrointestinal TB is one of the three forms.The disease can mimic other intra-abdominal conditions,leading to delayed diagnosis owing to the absence of specific symptoms.While gastric outlet obs-truction(GOO)remains a frequent complication,its incidence has declined with the advent of proton pump inhibitors and Helicobacter pylori eradication therapy.Gastroduodenal TB can cause upper gastrointestinal hemorrhage,obstruction,and malignancy-like tumors.CASE SUMMARY A 23-year-old male presented with recurrent epigastric pain,distension,nausea,vomiting,and weight loss,prompting a referral to a gastroenterologist clinic.Endoscopic examination revealed distorted gastric mucosa and signs of chronic inflammation.However,treatment was interrupted,possibly owing to vomiting or comorbidities such as human immunodeficiency virus infection or diabetes.Subsequent surgical intervention revealed a dilated stomach and diffuse thickening of the duodenal wall.Resection revealed gastric wall effacement with TB.CONCLUSION Primary gastric TB is rare,frequently leading to GOO.Given its rarity,suspicions should be promptly raised when encountering relevant symptoms,often requiring surgical intervention for diagnosis and treatment.

Appendiceal intussusception complicated by adenocarcinoma of the cecum:A case report

BACKGROUND Appendiceal intussusception is a pathological condition in which the appendix is inverted into the cecum,which may cause symptoms that resemble those of other gastrointestinal disorders and may induce intestinal obstruction.The rarity of this case presentation is the co-occurrence of appendiceal intussusception and cecal adenocarcinoma,a combination that to our knowledge has not previously been reported in the medical literature.This case provides new insights into the complexities of diagnosing and managing overlapping pathologies.CASE SUMMARY A 25-year-old woman presented with persistent periumbilical pain and bloody stools.An initial biopsy showed cecal cancer;however,subsequent colonoscopy and computed tomography findings raised the suspicion of appendiceal intussus-ception,which was later confirmed postoperatively.This unique case was charac-terized by a combination of intussusception and adenocarcinoma of the cecum.The intervention included a laparoscopic right hemicolectomy,which led to the histopathological diagnosis of mucinous adenocarcinoma with appendiceal intussusception.The patient recovered well postoperatively and was advised to initiate adjuvant chemotherapy.This case highlights not only the importance of considering appendiceal intussusception in the differential diagnosis,but also the possibility of appendicitis and the atypical presentation of neoplastic lesions.CONCLUSIONS Physicians should consider the possibility of appendiceal intussusception in cases of atypical appendicitis,particularly when associated with neoplastic presentation.

Multilocular thymic cysts can be easily misdiagnosed as malignant tumor on computer tomography:A case report

BACKGROUND Multilocular thymic cyst(MTC)is a rare mediastinal lesion which is considered to occur in the process of acquired inflammation.It is usually characterized by well-defined cystic density and is filled with transparent liquid.CASE SUMMARY We report on a 39-year-old male with a cystic-solid mass in the anterior mediastinum.Computer tomography(CT)imaging showed that the mass was irregular with unclear boundaries.After injection of contrast agent,there was a slight enhancement of stripes and nodules.According to CT findings,it was diagnosed as thymic cancer.CONCLUSION After surgery,MTC accompanied by bleeding and infection was confirmed by pathological examination.The main lesson of this case was that malignant thymic tumor and MTC of the anterior mediastinum sometimes exhibit similar CT findings.Caution is necessary in clinical work to avoid misdiagnosis.

Tricuspid mass-curious case of Li-Fraumeni syndrome: A case report

BACKGROUND Li-Fraumeni syndrome(LFS)is a rare autosomal dominant cancer-predisposing syndrome,which can manifest as a polymorphic spectrum of malignancies.LFS is associated with an early onset in life,with the majority of cases occurring prior to the age of 46.Notwithstanding the infrequency of primary cardiac tumors,it behooves clinicians to remain vigilant in considering the differential diagnosis of such tumors in LFS patients who present with a cardiac mass.This is due to the markedly elevated risk for malignancy in this particular population,far surpassing that of the general populace.CASE SUMMARY Herein,we present a case of a 30-year-old female with LFS who was found to have a tricuspid valve leaflet mass.CONCLUSION This case exemplifies valuable learning points in the diagnostic approach for this exceptionally rare patient population.

Patient satisfaction and follow-up adherence to glaucoma case management clinic in China

AIM:To assess glaucoma patient satisfaction and follow-up adherence in case management and identify associated predictors to improve healthcare quality and patient outcomes.METHODS:In this cross-sectional study,a total of 119 patients completed a Patient Satisfaction Questionnaire-18 and a sociodemographic questionnaire.Clinical data was obtained from the case management system.Follow-up adherence was defined as completing each follow-up within±30d of the scheduled time set by ophthalmologists during the study period.RESULTS:Average satisfaction scored 78.65±7,with an average of 4.39±0.58 across the seven dimensions.Age negatively correlated with satisfaction(P=0.008),whilst patients with follow-up duration of 2 or more years reported higher satisfaction(P=0.045).Multivariate logistics regression analysis revealed that longer follow-up durations were associated with lower follow-up adherence(OR=0.97,95%CI,0.95-1.00,P=0.044).Additionally,patients with suspected glaucoma(OR=2.72,95%CI,1.03-7.20,P=0.044)and those with an annual income over 100000 Chinese yuan demonstrated higher adherence(OR=5.57,95%CI,1.00-30.89,P=0.049).CONCLUSION:The case management model proves effective for glaucoma patients,with positive adherence rates.The implementation of this model can be optimized in the future based on the identified factors and extended to glaucoma patients in more hospitals.

Analysis of the causes of primary revision after unicompartmental knee arthroplasty: A case series

BACKGROUND Unicompartmental knee arthroplasty(UKA)has great advantages in the treatment of unicompartmental knee osteoarthritis,but its revision rate is higher than that of total knee arthroplasty.AIM To summarize and analyse the causes of revision after UKA.METHODS This is a retrospective case series study in which the reasons for the first revision after UKA are summarized.We analysed the clinical symptoms,medical histories,laboratory test results,imaging examination results and treatment processes of the patients who underwent revision and summarized the reasons for primary revision after UKA.RESULTS A total of 13 patients,including 3 males and 10 females,underwent revision surgery after UKA.The average age of the included patients was 67.62 years.The prosthesis was used for 3 d to 72 months.The main reasons for revision after UKA were improper suturing of the surgical opening(1 patient),osteophytes(2 patients),intra-articular loose bodies(2 patients),tibial prosthesis loosening(2 patients),rheumatoid arthritis(1 patient),gasket dislocation(3 patients),anterior cruciate ligament injury(1 patient),and medial collateral ligament injury with residual bone cement(1 patient).CONCLUSION The causes of primary revision after UKA were gasket dislocation,osteophytes,intra-articular loose bodies and tibial prosthesis loosening.Avoidance of these factors may greatly reduce the rate of revision after UKA,improve patient satisfaction and reduce medical burden.

Multi-systemic melioidosis in a patient with type 2 diabetes in nonendemic areas:A case report and review of literature

BACKGROUND Melioidosis,an infectious disease caused by Burkholderia pseudomallei(B.pseudomallei),occurs endemically in Southeast Asia and Northern Australia and is a serious opportunistic infection associated with a high mortality rate.CASE SUMMARY A 58-year-old woman presented with scattered erythema on the skin of her limbs,followed by fever and seizures.B.pseudomallei was isolated successively from the patient’s urine,blood,and pus.Magnetic resonance imaging showed abscess formation involving the right forehead and the right frontal region.Subsequently,abscess resection and drainage were performed.The patient showed no signs of relapse after 4 months of follow-up visits post-treatment.CONCLUSION We present here a unique case of multi-systemic melioidosis that occurs in nonendemic regions in a patient who had no recent travel history.Hence,it is critical to enhance awareness of melioidosis in non-endemic regions.

Perforated gastric ulcer causing mediastinal emphysema: A case report

BACKGROUND Mediastinal emphysema is a condition in which air enters the mediastinum between the connective tissue spaces within the pleura for a variety of reasons.It can be spontaneous or secondary to chest trauma,esophageal perforation,medi-cally induced factors,etc.Its common symptoms are chest pain,tightness in the chest,and respiratory distress.Most mediastinal emphysema patients have mild symptoms,but severe mediastinal emphysema can cause respiratory and circulatory failure,resulting in serious consequences.CASE SUMMARY A 75-year-old man,living alone,presented with sudden onset of severe epigastric pain with chest tightness after drinking alcohol.Due to the remoteness of his residence and lack of neighbors,the patient was found by his nephew and brought to the hospital the next morning after the disease onset.Computed tomography(CT)showed free gas in the abdominal cavity,mediastinal emph-ysema,and subcutaneous pneumothorax.Upper gastrointestinal angiography showed that the esophageal mucosa was intact and the gastric antrum was perforated.Therefore,we chose to perform open gastric perforation repair on the patient under thoracic epidural anesthesia combined with intravenous anesthesia.An operative incision of the muscle layer of the patient's abdominal wall was made,and a large amount of subperitoneal gas was revealed.And a continued incision of the peritoneum revealed the presence of a perforation of approx-imately 0.5 cm in the gastric antrum,which we repaired after pathological examination.Postoperatively,the patient received high-flow oxygen and cough exercises.Chest CT was performed on the first and sixth postoperative days,and the mediastinal and subcutaneous gas was gradually reduced.CONCLUSION After gastric perforation,a large amount of free gas in the abdominal cavity can reach the mediastinum through the loose connective tissue at the esophageal hiatus of the diaphragm,and upper gastrointestinal angiography can clarify the site of perforation.In patients with mediastinal emphysema,open surgery avoids the elevation of the diaphragm caused by pneumoperitoneum compared to laparoscopic surgery and avoids increasing the mediastinal pressure.In addition,thoracic epidural anesthesia combined with intravenous anesthesia also avoids pressure on the mediastinum from mechanical ventilation.

Mechanical upper bowel obstruction caused by a large trichobezoar in a young woman: A very unusual case report

BACKGROUND Bezoars usually compile human fibers and debris.A special form of bezoar in case of psychologically altered individuals is the trichobezoar.It consists of voluntarily swallowed hair bulks and is normally removed via gastroscopy.Trichobezoars leading to ileus have rarely been reported.CASE SUMMARY A 24-year-old female patient presented to the emergency room with abdominal pain,nausea,and vomiting for 3 d.Her previous medical and psychiatric history was unremarkable.Laboratory analysis showed iron deficiency anemia,leukocytosis,and elevated liver enzymes.An abdominal CT scan revealed a dense structure in the patients’stomach which turned out to be a huge trichobezoar completely obstructing the pylorus.The trichobezoar had to be removed surgi-cally.During her postoperative course,a subcutaneous seroma formed.After a single puncture,the rest of the recovery process was unremarkable,and the patient recovered fully.CONCLUSION A mechanical bowel obstruction is a potentially life-threatening event for every patient.In our case a young female was suffering from severe symptoms of an obstruction which might have resulted in serious harm without successful surgical management.

Diagnosis of poorly differentiated adenocarcinoma of the stomach by confocal laser endomicroscopy:A case report

BACKGROUND In recent years,confocal laser endomicroscopy(CLE)has become a new endoscopic imaging technology at the microscopic level,which is extensively performed for real-time in vivo histological examination.CLE can be performed to distinguish benign from malignant lesions.In this study,we diagnosed using CLE an asymptomatic patient with poorly differentiated gastric adenocarcinoma.CASE SUMMARY A 63-year-old woman was diagnosed with gastric mucosal lesions,which may be gastric cancer,in the small curvature of the stomach by gastroscopy.She consented to undergo CLE for morphological observation of the gastric mucosa.Through the combination of CLE diagnosis and postoperative pathology,the intraoperative CLE diagnosis was considered to be reliable.According to our experience,CLE can be performed as the first choice for the diagnosis of gastric cancer.CONCLUSION CLE has several advantages over pathological diagnosis.We believe that CLE has great potential in the diagnosis of benign and malignant gastric lesions.

Diagnostic challenges and individualized treatment of cervical adenocarcinoma metastases to the breast:A case report

BACKGROUND Cervical cancer is a rare primary tumor resulting in metastases to the breast with few cases reported in literature.Breast metastases are associated with poor prognosis.The following case highlights the diagnostic challenges associated with metastatic cervical cancer to the breast along with individualized treatment.CASE SUMMARY A 44-year-old G7P5025 with no significant past medical or surgical history presented with heavy vaginal to an outside emergency department where an exam and a pelvic magnetic resonance imaging showed a 4.5 cm heterogenous lobulated cervical mass involving upper two thirds of vagina,parametria and lymph node metastases.Cervical biopsies confirmed high grade adenocarcinoma with mucinous features.A positron emission tomography/computed tomography(PET/CT)did not show evidence of metastatic disease.She received concurrent cisplatin with external beam radiation therapy.Follow up PET/CT scan three months later showed no suspicious fluorodeoxyglucose uptake in the cervix and no evidence of metastatic disease.Patient was lost to follow up for six months.She was re-imaged on re-presentation and found to have widely metastatic disease including breast disease.Breast biopsy confirmed programmed death-ligand 1 positive metastatic cervical cancer.The patient received six cycles of carboplatin and paclitaxel with pembrolizumab.Restaging imaging demonstrated response.Patient continued on pembrolizumab with disease control.CONCLUSION Metastatic cervical cancer to the breast is uncommon with nonspecific clinical findings that can make diagnosis challenging.Clinical history and immunohistochemical evaluation of breast lesion,and comparison to primary tumor can support diagnosis of metastatic cervical cancer to the breast.Overall,the prognosis is poor,but immunotherapy can be considered in select patients and may result in good disease response.

Early adenocarcinoma mixed with a neuroendocrine carcinoma component arising in the gastroesophageal junction: A case report

BACKGROUND Early adenocarcinoma mixed with a neuroendocrine carcinoma(NEC)component arising in the gastroesophageal junctional(GEJ)region is rare and even rarer in young patients.Here,we report such a case in a 29-year-old Chinese man.CASE SUMMARY This patient presented to our hospital with a 3-mo history of dysphagia and regurgitation.Upper endoscopy revealed an elevated nodule in the distal esophagus 1.6 cm above the GEJ line,without Barrett’s esophagus or involvement of the gastric cardia.The nodule was completely resected by endoscopic submu-cosal dissection(ESD).Pathological examination confirmed diagnosis of intra-mucosal adenocarcinoma mixed with an NEC component,measuring 1.5 cm.Immunohistochemically,both adenocarcinoma and NEC components were positive for P53 with a Ki67 index of 90%;NEC was positive for synaptophysin and chromogranin.Next-generation sequencing of 196 genes demonstrated a novel germline mutation of the ERCC3 gene in the DNA repair pathway and a germline mutation of the RNF43 gene,a common gastric cancer driver gene,in addition to pathogenic somatic mutations in P53 and CHEK2 genes.The patient was alive without evidence of the disease 36 mo after ESD.CONCLUSION Early adenocarcinoma with an NEC component arising in the distal esophageal side of the GEJ region showed evidence of gastric origin.

Ipsilateral retroperitoneal papillary renal cell carcinoma 27 years after simple nephrectomy for a renal abscess:A case report

BACKGROUND Cases of severe inflammatory renal disease and renal cell carcinoma(RCC)that occur simultaneously in the same kidney have been occasionally reported.However,extrarenal RCC that does not originate from the native kidney has rarely been reported.To our knowledge,this is the first reported case of RCC developing in the ipsilateral retroperitoneal space after a simple nephrectomy(SN)for inflammatory renal disease.CASE SUMMARY A 63-year-old woman was referred to our hospital following the incidental discovery of a left retroperitoneal mass without specific symptoms.Her medical history revealed a left SN 27 years ago due to a renal abscess.Magnetic resonance imaging of the abdomen revealed three oval masses in the left retroperitoneum.The masses were successfully excised,and subsequent pathology confirmed papillary RCC.After surgery,the patient remained disease-free for 11 years without adjuvant therapy.CONCLUSION Clinicians should be vigilant of RCC in patients with retroperitoneal masses,especially after SN for inflammatory renal disease.

Upadacitinib for refractory ulcerative colitis with primary nonresponse to infliximab and vedolizumab:A case report

BACKGROUND Many patients with ulcerative colitis(UC)do not respond well to,or tolerate conventional and biological therapies.There is currently no consensus on the treatment of refractory UC.Studies have demonstrated that the selective Janus kinase 1 inhibitor upadacitinib,a small-molecule drug,is effective and safe for treating UC.However,no studies have revealed that upadacitinib is effective in treating refractory UC with primary nonresponse to infliximab and vedolizumab.CASE SUMMARY We report the case of a 44-year-old male patient with a chief complaint of bloody diarrhoea with mucus and pus,in addition to dizziness.The patient had recurrent disease after receiving mesalazine,prednisone,azathioprine,infliximab and vedolizumab over four years.Based on the endoscopic findings and pathological biopsy,the patient was diagnosed with refractory UC.In particular,the patient showed primary nonresponse to infliximab and vedolizumab.Based on the patient’s history and recurrent disease,we decided to administer upadacitinib.During hospitalisation,the patient was received upadacitinib under our guidance.Eight weeks after the initiation of upadacitinib treatment,the patient’s symptoms and endoscopic findings improved significantly.No notable adverse reactions have been reported to date.CONCLUSION Our case report suggests that upadacitinib may represent a valuable strategy for treating refractory UC with primary nonresponse.
