In this editorial,we discuss a recently published manuscript by Blüthner et al in the World Journal of Gastroenterology,with a specific focus on the delayed diagnosis of inflammatory bowel disease(IBD).IBD,which includes Crohn's disease and ulcerative colitis,is a chronic intestinal disorder.A time lag may exist between the onset of inflammation and the appearance of signs and symptoms,potentially leading to an incorrect or delayed diagnosis,a situation referred to as the delayed diagnosis of IBD.Early diagnosis is crucial for effective patient treatment and prognosis,yet delayed diagnosis remains common.The reasons for delayed diagnosis of IBD are numerous and not yet fully understood.One key factor is the nonspecific nature of IBD symptoms,which can easily be mistaken for other conditions.Additionally,the lack of specific diagnostic methods for IBD contributes to these delays.Delayed diagnosis of IBD can result in numerous adverse consequences,including increased intestinal damage,fibrosis,a higher risk of colorectal cancer,and a decrease in the quality of life of the patient.Therefore,it is essential to diagnose IBD promptly by raising physician awareness,enhancing patient education,and developing new diagnostic methods. 展开更多

AIM:To assess the clinical presentations and outcomes of idiopathic orbital inflammatory pseudotumor(IOIP)patients with orbital wall bone destruction(OWBD)and to propose an expanded classification system that includes bone destruction.METHODS:The study retrospectively reviewed clinical presentations,imaging findings,treatment modalities,and outcomes of six patients diagnosed histopathologically with IOIP and OWBD at the Beijing Tongren Hospital,Capital Medical University between October 2018 and June 2021.RESULTS:Over two years,6(10%)of 60 IOIP patients at our hospital exhibited OWBD,but this may overrepresent severe cases.The cohort consisted of three men and three women,aged 17 to 60y(mean 35.5±16.1y).Presenting symptoms included proptosis,eyelid swelling,decreased visual acuity with pain,and palpable mass.Imaging revealed multiple anatomical structures involved with the medial wall being the most common site of bone destruction.Histopathological examination showed classic type in five patients and sclerosing type in one patient.All patients underwent surgical resection followed by methylprednisolone treatment.Follow-up(mean 30.3±3.1mo)indicated three patients had no recurrence,while others had varying degrees of symptom persistence or recurrence.CONCLUSION:IOIP with bone destruction is a rare but significant subtype that mimics malignancy,leading to potential diagnostic and therapeutic challenges.Our findings suggest that complete surgical resection combined with adjunctive glucocorticoid therapy can yield favorable outcomes.However,larger-scale studies are needed to further optimize therapeutic approaches. 展开更多

The challenge of diagnosis delay in inflammatory bowel disease(IBD)has emerged as a significant concern for both patients and healthcare professionals.The widely accepted notion that there is an extended time frame from the onset of symptoms to the definitive diagnosis is often attributed to the heterogeneity of IBD and the non-specificity of clinical manifestations.Specific to patients with Crohn’s disease,the issue of delayed diagnosis appears to be more pronounced across different regions globally.The intricate interplay of real-world factors has led to debates regarding the primary contributors to these diagnostic delays.Drawing a comparison solely between patients and physicians and implicating the latter as the predominant influence factor may fall into a simplistic either-or logical trap that may obscure the truth.This letter,grounded in published evidence,explores areas for improvement in a forthcoming paper within the field,hoping to pinpoint the culprit behind the diagnosis delay issue for IBD patients rather than simply attributing it to so-called“physician-dependent factors”.Our objective is to motivate healthcare providers and policymakers in relevant fields to reflect on strategies for addressing this problem to reduce diagnostic delays and enhance patient outcomes. 展开更多

BACKGROUND Crohn’s disease(CD)is often misdiagnosed as intestinal tuberculosis(ITB).However,the treatment and prognosis of these two diseases are dramatically different.Therefore,it is important to develop a method to identify CD and ITB with high accuracy,specificity,and speed.AIM To develop a method to identify CD and ITB with high accuracy,specificity,and speed.METHODS A total of 72 paraffin wax-embedded tissue sections were pathologically and clinically diagnosed as CD or ITB.Paraffin wax-embedded tissue sections were attached to a metal coating and measured using attenuated total reflectance fourier transform infrared spectroscopy at mid-infrared wavelengths combined with XGBoost for differential diagnosis.RESULTS The results showed that the paraffin wax-embedded specimens of CD and ITB were significantly different in their spectral signals at 1074 cm^(-1) and 1234 cm^(-1) bands,and the differential diagnosis model based on spectral characteristics combined with machine learning showed accuracy,specificity,and sensitivity of 91.84%,92.59%,and 90.90%,respectively,for the differential diagnosis of CD and ITB.CONCLUSION Information on the mid-infrared region can reveal the different histological components of CD and ITB at the molecular level,and spectral analysis combined with machine learning to establish a diagnostic model is expected to become a new method for the differential diagnosis of CD and ITB. 展开更多

Hepatic inflammatory pseudotumor(IPT)is a benign lesion characterized by chronic infiltration of inflammatory cells and fibrosis that clinically,radiologically,and pathologically mimics malignancy.However,the epidemiology of IPTs remains unclear.IPTs are often misdiagnosed as malignant lesions because of the lack of characteristic features.We present the case of a 32-year-old man that was misdiagnosed as intrahepatic cholangiocarcinoma by CECT,CEMRI,and CEUS,which was finally confirmed as IPT by fine-needle liver biopsy.In this report,the key factor in the diagnosis of liver inflammatory masses was the presence of hepatic perfusion disorder. 展开更多

Orbital inflammatory disease(OID) represents a collec tion of inflammatory conditions affecting the orbit. OID is a diagnosis of exclusion, with the differential diagno sis including infection, systemic inflammatory conditions and neoplasms, among other conditions. Inflammatory conditions in OID include dacryoadenitis, myositis, cel lulitis, optic perineuritis, periscleritis, orbital apicitis, and a focal mass. Sclerosing orbital inflammation is a rare condition with a chronic, indolent course involving dense fibrosis and lymphocytic infiltrate. Previously though to be along the spectrum of OID, it is now considered a distinct pathologic entity. Imaging plays an importan role in elucidating any underlying etiology behind orbita inflammation and is critical for ruling out other condi tions prior to a definitive diagnosis of OID. In this re view, we will explore the common sites of involvemen by OID and discuss differential diagnosis by site and key imaging findings for each condition. 展开更多

Pneumonia and acute respiratory distress syndrome are common and important causes of respiratory failure in the intensive care unit with a significant impact on morbidity, mortality and health care utilization despite early antimicrobial therapy and lung protective mechanical ventilation. Both clinical entities are characterized by acute pulmonary inflammation in response to direct or indirect lung injury. Adjunct anti-inflammatory treatment with corticosteroids is increasingly used, although the evidence for benefit is limited. The treatment decisions are based on radiographic, clinical and physiological variables without regards to inflammatory state. Current evidence suggests a role of biomarkers for the assessment of severity, and distinguishing sub-phenotypes (hyperinflammatory versus hypo-inflammatory) with important prognostic and therapeutic implications. Although many inflammatory biomarkers have been studied the most common and of interest are C-reactive protein, procalcitonin, and pro-inflammatory cytokines including interleukin 6. While extensively studied as prognostic tools (prognostic enrichment), limited data are available for the role of biomarkers in determining appropriate initiation, timing and dosing of adjunct anti-inflammatory treatment (predictive enrichment) 展开更多

BACKGROUND This report describes a case of intracranial multiple inflammatory pseudotumors(IP)after endoscopic resection of a craniopharyngioma,which is relatively rarely reported in the literature,and neurosurgeons should be aware of its existence.CASE SUMMARY Herein,we report the case of a 56-year-old man who developed decreased visual acuity and blurred vision without obvious cause or inducement on April 27,2020.To seek further treatment,he went to the Department of Neurosurgery,Clinical Medical College,Yangzhou University.After falling ill,there was no nausea,vomiting,limb convulsions,obvious disturbance of consciousness,speech disorders,cough,or persistent fever.The neurological examination findings were normal,and pituitary magnetic resonance imaging(MRI)revealed multiple nodules with abnormal signals in the sellar region.The diagnosis was craniopharyngioma.We performed total resection of the tumor via transnasal endoscopy,and the postoperative pathology suggested that the type of tumor was craniopharyngioma.Six months after the operation,the patient experienced sudden hearing loss in the right ear,tinnitus in both ears,and numbness on the right side of the face and head.Meanwhile,cranial MRI showed multiple IP.After steroid hormone and anti-inflammatory therapy,the above symptoms did not significantly improve.Finally,the patient's symptoms were well improved by surgery,and the postoperative pathological diagnosis was multiple IP.CONCLUSION Intracranial inflammatory pseudotumor is a benign disease with slow progression,but the clinical symptoms and imaging findings are not typical,there are no pathological findings,and the diagnosis is relatively difficult.Most of the cases are treated by surgical resection,and the prognosis is good after surgery. 展开更多

Following the international guidelines criteria an adequate"diagnostic conclusion"of inflammatory bowel disease(IBD)can be achieved only if clinical,endoscopic and laboratory findings,together with sample technical adequacy and unequivocal histomorphological signs of the disease are available.Thus,a conclusive diagnosis requires a complex combination of clinical, endoscopic and histological data.A considerable number of endoscopic biopsies obtained from IBD patients do not meet the above-mentioned requirements.The aim of the present proposal is to introduce a binary system of evaluation in the"diagnostic conclusion"of the histopathological report that will help to simplify the clinical decisions and consequent patient management.In patients with no history of disease,the pathologist should classify the biopsies in"Diagnostic",when the criteria established by the international guidelines are satisfied and"not diagnostic"when one or more of the above-mentioned criteria are not met. The term"not diagnostic"should replace"highly suggestive"and"probable".This new terminology could avoid ambiguous expressions that encourage the clinician to classify the patient as affected by IBD without fulfilling all of the requirements for an accurate diagnostic approach. 展开更多

Accurate diagnosis of predominantly colonic inflammatory bowel disease(IBD) is not possible in 30% of patients. For decades, scientists have worked to find a solution to improve diagnostic accuracy for IBD, encompassing Crohn's colitis and ulcerative colitis. Evaluating protein patterns in surgical pathology colectomy specimens of colonic mucosal and submucosal compartments, individually, has potential for diagnostic medicine by identifying integrally independent, phenotype-specific cellular and molecular characteristics. Mass spectrometry(MS) and imaging(I) MS are analytical technologies that directly measure molecular species in clinical specimens, contributing to the in-depth understanding of biological molecules. The biometric-system complexity and functional diversity is well suited to proteomic and diagnostic studies. The direct analysis of cells and tissues by Matrix-Assisted-Laser Desorption/Ionization (MALDI) MS/IMS has relevant medical diagnostic potential. MALDI-MS/IMS detection generates molecular signatures obtained from specific cell types within tissue sections. Herein discussed is a perspective on the use of MALDI-MS/IMS and bioinformatics technologies for detection of molecular-biometric patterns and identification of differentiating proteins. I also discuss a perspective on the global challenge of transferring technologies to clinical laboratories dealing with IBD issues. The significance of serologic-immunometric advances is also discussed. 展开更多

An inflammatory pseudotumor (IPT) is a relatively rare lesion characterized by chronic inf iltration of inflammatory cells and areas of f ibrosis. IPTs are diff icult to diagnose because of the absence of specif ic symptoms or of characteristic hematological or radiological f indings. In this study, a case of a woman aged over 70 years was reported, who presented with a general malaise lasting more than two months. A computed tomography scan demonstrated a diffusely spread lesion of the liver with a portal vein occlusion and a splenic lesion surrounded by a soft density layer. Since the percutaneous liver biopsy showed f indings that suggested an IPT, although the radiological f indings did not exclude the possibility of a malignancy, we performed a percutaneous spleen biopsy to enable a more defi nitive diagnosis. The microscopic f indings from the spleen specimen lead us to a diagnosis of IPT involving the liver and spleen. Sub-sequent steroid pulse therapy was effective, and rapid resolution of the disease was observed. 展开更多

Hepatic inflammatory pseudotumors are uncommon benign lesions.Accurately diagnosing hepatic inflammatory pseudotumor can be very challenging because the clinical presentation and radiological appearances are nonspecific and cannot be certainly distinguished from malignant neoplastic processes.Herein,we present a case of hepatic IPT in an 8-yearold boy who presented to clinic with a 3-mo history of a tender hepatic mass,fever of unknown origin,and9-kg weight loss.The physical examination was notable for tender hepatomegaly.Laboratory investigations were notable for a normal hepatic profile and elevated erythrocyte sedimentation rate and C-reactive protein.A T2-attenuated magnetic resonance imaging scan of the abdomen showed a 4.7 cm x 4.7 cm x 6.6cm,contrast-enhancing,hyper-intense,well-defined lesion involving the right hepatic lobe.In view of the unremitting symptoms,tender hepatomegaly,thrombosed right hepatic vein,nonspecific radiological findings,and high suspicion of a deep-seated underlying infection or malignancy,a right hepatic lobectomy was recommended.Microscopically,the hepatic lesion exhibited a mixture of inflammatory cells(histiocytes,plasma cells,mature lymphocytes,and occasional multinucleated giant cells) in a background of dense fibrous tissue.Immunohistochemically,the cells stained negative for SMA,ALK-1,CD-21 and CD-23,diffusely positive for CD-68,and focally positive for lgG4.The final histopathological diagnosis was consistent with hepatic IPT.At the postoperative 4-mo follow-up,the patient was asymptomatic without radiological evidence of recurrence. 展开更多

AIM:To determine the clinical features of the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor and its relationship with paranasal sinusitis.· METHODS:A retrospective analysis of 46 patients who received surgical treatment at the Department of Ophthalmology,Beijing Tongren Hospital,Capital Medical University for the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor from October 2010 to December 2012.Each patient underwent magnetic resonance imaging(MRI) of the orbits and the 4paranasal sinuses.Disease status and the level of serum immunoglobulin G4(IgG4) was measured before and6 mo after surgery.· RESULTS:The initial clinical feature of the idiopathic dacryoadenitis type of orbital inflammatory pseudotumor was redness or swelling of the eyelids.Masses were palpated in the area of the lacrimal gland in some patients.Of the 46 patients,16 also suffered from sinusitis(34.8%),with 14 cases of ethmoid sinusitis,8cases of maxillary sinusitis,9 cases of sphenoid sinusitis,and 8 cases of frontal sinusitis.Of the 16 patients with sinusitis,4 patients had a medical history of rhinitis(range:10mo to 15 y previously),10 patients had occasional nasal congestion,and 2 patients had no nasal congestion.Thirteen of the 46 patients had elevated serum IgG4 levels.Nine of these 13 patients had MRI signs of sinusitis.All patients(n=46) received oral glucocorticoid treatment for approximately 3mo after surgery.No sign of recurrence was found in the orbital MRI 6mo after surgery.Of the 16 patients with sinusitis,9cases of elevated serum IgG4 levels improved after treatment with decreased serum IgG4 level and 7 cases of normal serum IgG4 levels remained unchanged.· CONCLUSION:Some patients with the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor may also suffer from paranasal sinusitis.The incidence of paranasal sinusitis was much higher in patients with IgG4-elevated dacryoadenitis subtype orbital inflammatory pseudotumor than in those with normal IgG4 levels.Dacryoadenitis subtype orbital inflammatory pseudotumor and paranasal sinusitis may both the clinical manifestations of IgG4-related disease involved in different locations. 展开更多

BACKGROUND:Hepatic inflammatory pseudotumor(IPT)is classified into 2 types based on IgG 4 stain:IgG 4-related and non-IgG4-related; the two types differ not only in their pathological characteristics, but also in the clinical features. This study aimed to investigate the MR character of hepatic IPT,and differentiate the IgG4-related IPT from the non-IgG4-related IPT.METHODS:Twenty-five patients with 27 histologically proven hepatic IPTs were retrospectively analyzed. Ten lesions were diagnosed as IgG4-related IPT, and the other 17 as non-IgG4-related IPT. The MR signal features on T1,T2-weighted, dynamic-enhanced, and diffusion-weighted imaging were evaluated and compared. RESULTS:The dominant lesions were subcapsularly distributed(n=17, 63.0%) with clear boundary(n=20, 74.1%), and showed progressive enhancement pattern(n=21, 77.8%) with diffuse homogeneous(n=12, 44.4%) or heterogeneous(n=8,29.6%) hyperintensity, accompanied by delayed capsule-like enhancement(n=17, 63.0%) and central nonenhanced areas(n=18, 66.7%). Morphological features(P>0.05) were not sufficient to differentiate IgG4-related IPT from non-IgG4-related IPT; the wash-out pattern was only found in 2 IgG 4-related IPT, while the progressive enhancement pattern was more common in the non-IgG4-related lesions(n=16)(P=0.022).During portal and delayed phases, iso-/hypoenhanced lesions were only seen in 3 IgG4-related IPT, and circular-enhanced lesions(n=5) existed exceptionally in the non-IgG4-related group with significant differences(P=0.029 and 0.027). Most IgG4-related IPTs had lower apparent diffusion coefficient compared with the liver parenchyma(n=6), while most non-IgG4-related IPTs had higher apparent diffusion coefficient value(n=13)(P=0.046).CONCLUSIONS:Although MR images of hepatic IPT have certain characteristics, they are not enough to differentiate IgG4-related IPT from non-IgG4-related IPT. The enhancement pattern, signal features on portal and delayed phases, and the apparent diffusion coefficient value of the lesion may be helpful for the diagnosis. 展开更多

Hepatic inflammatory pseudotumor (IPT) is a rare benign non-neoplastic lesion characterized by proliferating fibrous tissue infiltrated by inflammatory cells. The exact etiology of IPT remains unclear. Although the association of IPT with systemic inflammatory disorders has been well established, a specific relationship with cholangitis is distinctly rare. We report a case of spontaneous regression of hepatic IPT with primary biliary cirrhosis (PBC). To date, only two cases of IPT with PBC have been reported. In our case, however, IPT developed during the course of improvement of cholangitis of PBC induced by effective treatment, differing from two previously reported cases. Our case indicates that the development of IPT does not also relate to the activity of cholangitis and/or hyper gamma-globulinemia, since our case was confirmed radiologically to be free of IPT when biliary enzymes and immunoglobulins were much higher than the corresponding values on admission. Comparison of our case with the two previously reported cases suggests that IPT occurring with PBC does not represent the same disease entity or be a bystander for PBC. 展开更多
