Currently, AIP should be diagnosed based on combination of clinical, serological, morphological, and histopathological features. When diagnosing AIP, it is most important to differentiate it from pancreatic cancer. Diagnostic criteria for AIP, proposed by the Japan Pancreas Society in 2002 first in the world, were revised in 2006. The criteria are based on the minimum consensus of AIP and aim to avoid misdiagnosing pancreatic cancer as far as possible, but not for screening AIR The criteria consist of the following radiological, serological, and histopathological items： （1） radiological imaging showing narrowing of the main pancreatic duct and enlargement of the pancreas, which are characteristic of the disease; （2） laboratory data showing abnormally elevated levels of serum y-globulin, IgG or IgG4, or the presence of autoantibodies; （3） histopathological examination of the pancreas demonstrating marked fibrosis and prominent infiltration of lymphocytes and plasma cells, which is called lymphoplasmacytic sclerosing pancreatitis （LPSP）. For a diagnosis of AIP, criterion 1 must be present, together with criterion 2 and/ or criterion 3. However, it is necessary to exclude malignant diseases such as pancreatic or biliary cancer.展开更多

Above all, AIP is a very attractive disease to clinicians in terms of its dramatic response to the oral steroid therapy in contrast to ordinary chronic pancreatitis. Although many characteristic findings of AIP have been described, definite diagnostic criteria have not been fully established. In the year 2002, the Japan Pancreas Society published the diagnostic criteria of AIP and many clinicians around the world use these criteria for the diagnosis of AIP. The diagnostic criteria proposed by the Japan Pancreas Society, however, are not completely satisfactory and some groups use their own criteria in reporting AIP. This review discusses several potential limitations of current diagnostic criteria for this increasingly recognized condition. The manuscript is organized to emphasize the need for convening a consensus to develop improved diagnostic criteria.展开更多

The results were as follows: (1)95.2% of researchers considered the comprehensibility of the CCMD-2 diagnstic criteria good. Within the ten major categories, comprehensibility ranged from 85.7% to 100%. (2) Of those surveyed concerning the acceptibility of the CCCMD-2 diagnostic criteria, 85.9% considered them acceptable. In individual classifications, the rate ranged from 74.1% to 95.2%. (3) 1498 cases were tested. The overall applicability rate which indicated the consistency between the CCMD-2 result and the actual clinical diagnoses was found to be 87.6%, (averaging Kappa = 0.82,P<0.01), better than those obtained from non-Chinese systems of diagnosis.展开更多

文摘Objective:Elderly atopic dermatitis(AD)is a newly identified subtype of AD.Whether specific diagnostic criteria are needed for elderly AD has been debated.This study aimed to propose diagnostic criteria for elderly AD and evaluate the sensitivity.Methods:A hospital-based study was conducted.We screened the clinical features of 1,312 patients with AD of different ages in 1 cohort and proposed a set of diagnostic criteria for elderly AD.The criteria were then validated in another cohort of 223 patients clinically diagnosed with elderly AD by dermatologists specialized in AD to examine the diagnostic sensitivity compared with other criteria by chi-square test.Results:Based on the patients’clinical features,a set of diagnostic criteria for elderly AD were proposed.The new diagnostic criteria showed significantly higher sensitivity than the classical diagnostic criteria(P<0.001),especially for mild and moderate AD(P<0.001).Of all 223 patients with elderly AD,93.3%fulfilled our criteria,while only 43.5%,65.5%,and 52.0%fulfilled the Hanifin and Rajka criteria,the Japanese Dermatology Academy criteria,and the United Kingdom Working Party criteria,respectively.Conclusion:The newly proposed criteria for elderly AD yielded high diagnostic sensitivity,particularly for mild and moderate AD.
文摘In the last decade,many investigators including us have reported the negative impact of preoperative sarcopenia or low skeletal muscle mass on outcomes after surgery including hepato-biliary-pancreatic(HBP)surgery such as liver transplantation,liver surgery,biliary surgery,and pancreatic surgery(1-5).In addition to low skeletal muscle mass,the abnormality of body compositions,decreased muscle quality and visceral obesity,has been clarified to be also negatively associated with poor outcomes after HBP surgery(2-5).Consequently,it was easily supposed that co-existence of sarcopenia and obesity,called sarcopenic obesity(SO),had more strong negative impact on outcomes.Actually,not a few studies have demonstrated negative clinical impact of SO on outcomes after HBP surgery using various definitions for SO(6-10).We reported that patients with SO,defined by low skeletal muscle mass with high visceral fat to subcutaneous fat ratio evaluated by preoperative computed tomography(CT)image,had significant worse survival than non-sarcopenia patients and patients with sarcopenia only after liver transplantation,hepatic resection,and pancreatic resection(6-9).

文摘Background and Aims:Metabolic dysfunction-associ-ated fatty liver disease(MAFLD)is a new concept,pro-posed in 2020;however,its applicability in Asia populations has yet to be evaluated.Therefore,we aimed to compare the difference in epidemiological and clinical characteris-tics between MAFLD and non-alcoholic fatty liver disease(NAFLD)among Asian populations.Methods:Based on the Jinchang cohort,30,633 participants were collected.The prevalence and incidence of MAFLD and NAFLD were used to analyze the epidemic characteristics and its overlapping effects.In addition,the corresponding clinical character-istics of the two diagnostic criteria populations were com-pared.Results:The prevalence rates of MAFLD and NAFLD were 21.03%and 18.83%,respectively.After an average 2.28-year follow-up,the incidence densities of MAFLD and NAFLD were 41.58 per 1,000 person-years and 37.69 per 1,000 person-years,respectively.With the increase of baseline age,body mass index(BMI),and waist circumfer-ence(WC)levels,the prevalence and incidence of MAFLD and NAFLD were on the rise(all ptrend<0.05).Among the total patients diagnosed at baseline or follow-up,most pa-tients had both MAFLD and NAFLD,accounting for 78.84%and 82.88%,respectively.Compared with NAFLD,MAFLD patients had greater proportions of males and metabolic diseases(diabetes,dyslipidemia),and had higher BMI,WC,liver enzymes,blood glucose,and lipid levels in the base-line diagnosis patients(p<0.05).Additionally,lean MAFLD patients had higher metabolic disorders than lean NAFLD patients(p<0.05).Conclusions:Compared with NAFLD,the newly proposed definition of MAFLD is more practical and accurate,and it can help identify more fatty liver pa-tients with high-risk diseases.
文摘Until a few years ago,celiac disease(CD)was thought to be a rare food intolerance that was confined to childhood and characterized by severe malabsorption and flat intestinal mucosa.Currently,CD is regarded as an autoimmune disorder that is common in the general population(affecting 1 in 100 individuals),with possible onset at any age and with many possible presentations.The identification of CD is challenging because it can begin not only with diarrhea and weight loss but also with atypical gastrointestinal(constipation and recurrent abdominal pain)and extra-intestinal symptoms(anemia,raised transaminases,osteoporosis,recurrent miscarriages,aphthous stomatitis and associated autoimmune disorders),or it could be completely symptomless.Over the last 20 years,the diagnostic accuracy of serology for CD has progressively increased with the development of highly reliable tests,such as the detection of IgA tissue transglutaminase and antiendomysial and IgG antideamidated gliadin peptide antibodies.The routine use of antibody markers has allowed researchers to discover a very high number of‘borderline’cases,characterized by positive serology and mild intestinal lesions or normal small intestine architecture,which can be classified as potential CD.Therefore,it is evident that the‘old celiac disease’with flat mucosa is only a part of the spectrum of CD.It is possible that serology could identify CD in its early stages,before the appearance of severe intestinal damage.In cases with a positive serology but with mild or absent intestinal lesions,the detection of HLA-DQ2 and HLA-DQ8 can help reinforce or exclude the diagnosis of gluten sensitivity.

文摘Diabetes has become a major public health problem in China nowadays.There are almost 97 million diabetic patients nationwide.Latent autoimmune diabetes in adults(LADA)is a subtype of autoimmune diabetes.Although it has been reported for about 20 years,the diagnostic criteria of this disease remain controversial.The discussion mainly focused on serum autoantibodies,period of insulin need and age of diagnosis.Besides,β cell function,metabolic parameters,genetic factors and cell immunity may also contribute to the formulation of the criteria.Here,we aim to review and discuss the diagnostic criteria of latent autoimmune diabetes in adults.
文摘The Chinese Neurology and Psychiatry Association conducted a national field trial of its Chinese Classification and Diagnostic Criteria of Mental Disorders (CCMD-2) involov-ing 26 provinces and municipalities, 80 psychiatric institutes, and 224 professionals. The results were as follows: (1)95.2% of researchers considered the comprehensibility of the CCMD-2 diagnstic criteria good. Within the ten major categories, comprehensibility ranged from 85.7% to 100%. (2) Of those surveyed concerning the acceptibility of the CCCMD-2 diagnostic criteria, 85.9% considered them acceptable. In individual classifications, the rate ranged from 74.1% to 95.2%. (3) 1498 cases were tested. The overall applicability rate which indicated the consistency between the CCMD-2 result and the actual clinical diagnoses was found to be 87.6%, (averaging Kappa = 0.82,P<0.01), better than those obtained from non-Chinese systems of diagnosis.
文摘Acute pancreatitis(AP)is an inflammatory disease of the pancreas,which can progress to severe AP,with a high risk of death.It is one of the most complicated and clinically challenging of all disorders affecting the abdomen.The main causes of AP are gallstone migration and alcohol abuse.Other causes are uncommon,controversial and insufficiently explained.The disease is primarily characterized by inappropriate activation of trypsinogen,infiltration of inflammatory cells,and destruction of secretory cells.According to the revised Atlanta classification,severity of the disease is categorized into three levels:Mild,moderately severe and severe,depending upon organ failure and local as well as systemic complications.Various methods have been used for predicting the severity of AP and its outcome,such as clinical evaluation,imaging evaluation and testing of various biochemical markers.However,AP is a very complex disease and despite the fact that there are of several clinical,biochemical and imaging criteria for assessment of severity of AP,it is not an easy task to predict its subsequent course.Therefore,there are existing controversies regarding diagnostic and therapeutic modalities,their effectiveness and complications in the treatment of AP.The main reason being the fact,that the pathophysiologic mechanisms of AP have not been fully elucidated and need to be studied further.In this editorial article,we discuss the efficacy of the existing diagnostic and therapeutic modalities,complications and treatment failure in the management of AP.

文摘BACKGROUND Autoimmune enteropathy(AIE)is a rare disease whose diagnosis and long-term prognosis remain challenging,especially for adult AIE patients.AIM To improve overall understanding of this disease’s diagnosis and prognosis.METHODS We retrospectively analyzed the clinical,endoscopic and histopathological characteristics and prognoses of 16 adult AIE patients in our tertiary medical center between 2011 and 2023,whose diagnosis was based on the 2007 diagnostic criteria.RESULTS Diarrhea in AIE patients was characterized by secretory diarrhea.The common endoscopic manifestations were edema,villous blunting and mucosal hyperemia in the duodenum and ileum.Villous blunting(100%),deep crypt lymphocytic infiltration(67%),apoptotic bodies(50%),and mild intraepithelial lymphocytosis(69%)were observed in the duodenal biopsies.Moreover,there were other remarkable abnormalities,including reduced or absent goblet cells(duodenum 94%,ileum 62%),reduced or absent Paneth cells(duodenum 94%,ileum 69%)and neutrophil infiltration(duodenum 100%,ileum 69%).Our patients also fulfilled the 2018 diagnostic criteria but did not match the 2022 diagnostic criteria due to undetectable anti-enterocyte antibodies.All patients received glucocorticoid therapy as the initial medication,of which 14/16 patients achieved a clinical response in 5(IQR:3-20)days.Immunosuppressants were administered to 9 patients with indications of steroid dependence(6/9),steroid refractory status(2/9),or intensified maintenance medication(1/9).During the median of 20.5 months of followup,2 patients died from multiple organ failure,and 1 was diagnosed with non-Hodgkin’s lymphoma.The cumulative relapse-free survival rates were 62.5%,55.6%and 37.0%at 6 months,12 months and 48 months,respectively.CONCLUSION Certain histopathological findings,including a decrease or disappearance of goblet and Paneth cells in intestinal biopsies,might be potential diagnostic criteria for adult AIE.The long-term prognosis is still unsatisfactory despite corticosteroid and immunosuppressant medications,which highlights the need for early diagnosis and novel medications.

文摘Recent findings by Yamashita et al report a Kawasaki disease(KD)case with normal biomarker levels,challenging traditional diagnostic paradigms.This editorial explores the implications of such atypical KD presentations,emphasizing the need for novel biomarkers and revised diagnostic guidelines.The case underscores the limitations of current biomarkers,the importance of clinical judgment,and the necessity for comprehensive research to identify new diagnostic tools.Emerging technologies in proteomics and genomics offer potential avenues for discovering reliable biomarkers.Revisiting clinical guidelines to incorporate flexibility for atypical presentations is crucial.Ensuring timely and accurate KD diagnosis,even without elevated traditional biomarkers,prevents severe complications.Future advancements should focus on novel biomarkers to improve patient outcomes.
文摘BACKGROUND Septic arthritis,whether native or prosthetic,poses a significant challenge in clinical practice due to its potentially devastating consequences.Despite its clinical importance,there remains a dearth of comprehensive studies and standardized diagnostic criteria,particularly in the Kingdom of Saudi Arabia.AIM To investigate the epidemiology,microbiological profiles,and clinical characteristics of native and prosthetic septic joints in the Saudi Arabian population.METHODS Medical records of patients diagnosed with septic arthritis between January 1,2015,and December 31,2022,were retrospectively reviewed.Data regarding patient demographics,clinical presentation,microbiological cultures,treatment modalities,and outcomes were analyzed.RESULTS In a retrospective review of 52 cases of septic arthritis,a balanced gender distribution was observed(1:1 ratio),with the knee being the most commonly affected joint(80.8%).Methicillin-resistant Staphylococcus aureus predominated in native joints(24.2%),while Brucella spp.was more prevalent in prosthetic joints(21.1%).Joint preservation was achieved in most cases(84.6%),with no significant difference in clinical features between native and prosthetic joints.However,certain comorbidities were more common in native joint cases,including renal impairment(P=0.002),hemodialysis(P=0.004),heart disease(P=0.013),and chronic liver disease(P=0.048).At the same time,osteoarthritis was more prevalent in prosthetic joint cases(P=0.013).Vancomycin was the most frequently used antibiotic(26.9%),and most patients received antibiotics before joint aspiration(57.7%).Surgical intervention,predominantly arthrotomy,was required in most cases(32.7%).Notably,a significant association was found between joint type and mortality(odds ratio=0.587,P=0.048),as well as the Charlson comorbidity index and mortality(P=0.001).CONCLUSION This study highlighted distinctive microbiological profiles and etiological factors in septic arthritis cases in the Saudi Arabian population.
文摘Significant controversies exist with regards to the optimal management of lateral pelvic lymph nodes metastases(mLLN)in patients with low rectal cancer.The differing views held by Japanese and Western clinicians on the management of mLLN have been well documented.However,the adequacy of pelvic lymph node dissection(PLND)or neoadjuvant chemoradiation(NACRT)alone in addition to total mesorectal excision(TME)have recently come into question,due to the relatively high incidence of lateral local recurrences following PLND and TME,or NACRT and TME alone.Recently,a more selective approach to PLND has been suggested,involving a combination of neoadjuvant therapy,followed by PLND only to patients in whom the oncological benefit is likely to outweigh the risk of potential adverse events.A number of studies have attempted to retrospectively identify certain nodal characteristics on preoperative imaging,such as nodal size,appearance,and size reduction following neoadjuvant therapy.However,no consensus has been reached regarding the optimal criteria for a selective approach to PLND,partly due to the heterogeneity and retrospective nature of most of these studies.This review aims to provide an overview of recent evidence with regards to the diagnostic challenges,considerations for,and outcomes of the current management strategies for mLLN in rectal cancer patients.
文摘Autoimmune pancreatitis(AIP)is a rare disease clinically characterized by obstructive jaundice,unintentional weight loss,acute pancreatitis,focal pancreatic mass,and diabetes.AIP is classified into two subtypes-type 1 and type 2-according to pathological findings,clinical features,and serology test results,but some cases may be defined as type not otherwise in the absence of pathological findings and inflammatory bowel disease.To address the differences in diagnostic criteria by country,standard diagnostic criteria for AIP were proposed in 2011 by an international consensus of expert opinions.Differential diagnosis of AIP from pancreatic ductal adenocarcinoma is important but remains challenging for clinicians.Fortunately,all subtypes of AIP show dramatic response to steroid treatment.This review discusses the current perspectives on the diagnosis and management of AIP in clinical practice.
