Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multi-system disease that presents significant diagnostic challenges due to its complexity and low incidence (White and Dubey, 2023). It affects males and females equally, though males may exhibit more active disease at diagnosis and often require more aggressive treatment (Liu et al., 2023). The hallmark features of EGPA include delayed-onset asthma, eosinophilia in tissues and blood, and vasculitis affecting small to medium-sized arteries (White and Dubey, 2023). EGPA falls under the category of antineutrophil cytoplasmic antibody (ANCA)‍-associated vasculitis (AAV), whereas only about half of EGPA patients test positive for ANCA (Khoury et al., 2023).

OBJECTIVE: To investigate the independent risk factors for short-term mortality in patients with spontaneous cerebellar hemorrhage (SCH) based on Mimics software of medical image control system. METHODS: The clinical data of SCH patients treated at Shengjing Hospital of China Medical University from January, 2010 to December, 2021 was retrospectively analyzed and compared, including gender, age, underlyin g diseases, Glasgow coma scale (GCS) and blood pressure at admission, laboratory indicators, imaging data, and short-term (3 weeks after onset) survival status. The imaging examination parameters were accurately calculated using Mimics software, including hematoma volume, longest diameter, and maximum cross-sectional area of cerebellar hemorrhage. Multivariate Logistic regression analysis was used to evaluate the independent risk factors for short-term death in SCH patients. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of the four significant factors on short-term mortality in SCH patients. RESULTS: A total of 202 patients with SCH were included, of which 42 patients (20.8%) died within 3 weeks of onset and 160 patients (79.2%) survived. Univariate analysis showed that, compared with the survival group, the death group had significantly higher blood glucose, hematoma volume, hematoma longest diameter, hematoma maximum cross-sectional area, the ratio of hematoma maximum cross-section area and the corresponding posterior cranial fossa area, while GCS score was significantly lower, the distance from hematoma edge to the cerebral aqueduct center, and the distance from hematoma edge to the edge of brainstem were significantly shorter, the differences were statistically significant. Multivariate Logistic regression analysis showed that GCS score at admission [odds ratio (OR) = 0.875, 95% confidence interval (95%CI) was 0.767-0.998], hematoma volume (OR = 1.068, 95%CI was 1.022-1.115), the longest diameter of hematoma (OR = 1.086, 95%CI was 1.049-1.124), and the ratio of hematoma maximum cross-section area and the corresponding posterior cranial fossa area (OR = 1.119, 95%CI was 1.060-1.181) were independent risk factors for short-term mortality in SCH patients (all P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) for predicting short-term death of patients with SCH were 0.738, 0.839, 0.728 and 0.727, respectively. When the GCS score was 12 at admission, the sensitivity was 85.0% and the specificity was 57.1%. When the hematoma volume was 8.40 mL, the sensitivity was 95.2% and the specificity was 65.0%. When the longest diameter of the hematoma was 47.10 mm, the sensitivity was 57.1% and the specificity was 80.6%. When the ratio of hematoma maximum cross-section area and the corresponding posterior cranial fossa area was 0.11, the sensitivity was 88.1% and the specificity was 48.7%. CONCLUSIONS GCS score < 12 on admission, hematoma volume > 8.40 mL, hematoma longest diameter > 47.10 mm, the ratio of hematoma maximum cross-section area and the corresponding posterior cranial fossa area > 0.11 suggest a higher risk of short-term mortality in SCH patients.

Objective To evaluate the clinical characteristics and prognostic predictors of patients with diffuse alveolar hemorrhage (DAH) and/or interstitial lung disease (ILD) secondary to microscopic polyangiitis (MPA) in a Chinese general hospital. Methods We retrospectively reviewed the medical records of MPA patients admitted to internal medicine departments between the year 2002 and 2012. The patients were divided into the ILD, DAH, DAH combined with ILD (DAHILD), and no pulmonary involvement (NPI) groups according to pulmonary involvement patterns. The clinical characteristics at diagnosis were analyzed. The risk factors associated with short-term death and long-term death were identified with Logistic regression and Cox analysis.Results Of 193 newly diagnosed MPA patients, 181 patients were enrolled in the research, of which 19 had DAH alone, 96 had ILD alone, 18 had DAH and DAH concurrently, and 48 had NPI. The median of serum creatine level in the DAH group was 449 μmol/L, significantly higher than that in the ILD group (123 μmol/L, Nemenyi = -35.215, P = 0.045) and DAHILD group (359 μmol/L, Nemenyi = -43.609, P = 0.007). The median follow-up time was 67 (range: 1-199) months. Patients in the ILD group were older than those in the DAH group (median: 69 years vs. 57 years, Nemenyi = 43.853, P= 0.005). The patients with both DAH and ILD had combined features of the two subtypes, and the highest mortality (72.2% at the end of follow-up). The elevated white blood cell count was a risk factor for short-term death (OR = 1.103, 95%CI: 1.008-1.207, P = 0.032 for one month; OR = 1.103, 95%CI: 1.026-1.186, P = 0.008 for one year). Old age (HR= 1.044, 95%CI: 1.023-1.066, P < 0.001), cardiovascular system involvement (HR = 2.093, 95%CI: 1.195-3.665, P = 0.010), poor renal function (HR = 1.001, 95%CI: 1.000-1.002, P = 0.032) were risk factors for long-term death. Pulmonary infections (38/54) were the leading causes of death, especially for the patients with ILD. Besides, 49 patients suffered from pulmonary infections in the first year after diagnosis. Conclusions MPA patients who presented with different pulmonary involvement patterns have completely different clinical features. These subtypes probably have different pathogenesis and should be studied separately.

Objective: To explore the clinical value of von Willebrand Factor (vWF) and VITRO score (vWF:Ag/platelet count) in assessing disease progression in patients with HBV infection. Methods: Randomly collect relevant clinical data of 308 patients with HBV infection (including 154 cases of chronic hepatitis B, 66 cases of hepatitis B cirrhosis in compensatory period, 88 cases of hepatitis B cirrhosis in decompensated period) from December 1, 2018 to January 5, 2021 in the Second Affiliated Hospital of Chongqing Medical University. The vWF values are measured by a uniform optical method, and all data are included using a uniform standard. Analyze the difference and significance of plasma vWF level and VITRO score in chronic hepatitis B, hepatitis B cirrhosis in the compensatory phase and decompensated phase. Results: The plasma vWF level and VITRO score of the chronic hepatitis B group were (139.47±76.44) and (0.86±0.8), respectively, and the hepatitis B cirrhosis compensated group was (164.95±67.12 and 1.44±1.14), respectively. Hepatitis cirrhosis decompensated group were (317.48±103.32 and 6.81±4.98), respectively; plasma vWF level and VITRO score increased with the progression of HBV infection, and the difference was statistically significant (F=133.669,P=0.000F=137.598,P=0.000).The plasma vWF level and VITRO score in patients with hepatitis B cirrhosis were (185.65±85.07 and 2.3±2.37) in the Child-Pugh A group, (304.74±105.81 and 6.37±5.19) in the B grade group, and (369.48±73.238.28±5.38) in the C grade group; plasma vWF level and VITRO score in patients with hepatitis B cirrhosis increased with the increase of Child-Pugh grade, and the difference was statistically significant (F=60.236, P=0.000F=32.854, P=0.000). The area under the curve (AUC) of plasma vWF level and VITRO score for diagnosing the decompensated stage of hepatitis B cirrhosis were 0.897 [95% confidence interval (CI): 0.855-0.940, P＜0.01], 0.949 [95% CI: 0.916-0.982, P＜0.01). When the vWF level and VITRO score were taken as cut-off values of 238.5% and 1.65, respectively, the sensitivity of diagnosing the decompensated stage of hepatitis B cirrhosis was 79.5% and 94.3%, the specificity was 92.3% and 87.7%, and the positive predictive value was 80.5% and 94.3%, the negative predictive value was 91.9% and 97.5%, and the diagnostic accuracy was 88.6% and 89.3%. Among the patients with decompensated hepatitis B cirrhosis, the level of vWF in the group with gastrointestinal bleeding (367.24±68.29)% was significantly higher than that in the group without gastrointestinal bleeding (286.15±109.69)%, and the difference was statistically significant (P＜0.001) The VITRO score of the group with gastrointestinal bleeding (9.12±5.4) was significantly higher than that of the group without gastrointestinal bleeding (5.36±4.13), and the difference was statistically significant (P＜0.01). The vWF level in the spontaneous peritonitis group was (341.73±87.92)% higher than that in the non-spontaneous peritonitis group (296.32±111.74)%, and the difference was statistically significant (P＜0.05). There was no statistical difference in VITRO score between the two groups. significance. Conclusion: Plasma vWF level and VITRO score can evaluate the progression of liver disease and the degree of decompensation of liver cirrhosis in patients with HBV infection, and have a predictive effect on various complications after decompensation of liver cirrhosis, and have certain guiding significance for early intervention measures.

Duodenal leiomyosarcoma is a rare condition with a poor prognosis. Early diagnosis of duodenal leiomyosarcoma is challenging because it presents with nonspecific symptoms and endoscopic biopsies usually do not enable a definitive diagnosis. Duodenal leiomyosarcomas are diagnosed on the basis of the histopathological identification of a mesenchymal lesion composed of malignant tumor cells that on immunohistochemical examination is positive for smooth muscle actin and desmin. We report the case of a 38-year-old man who presented with gastrointestinal bleeding and obstruction who was diagnosed with duodenal leiomyosarcoma after surgical resection.

Ischemic colitis primarily affects the elderly with underlying disease, but it rarely occurs in young adults with risk factors, such as coagulopathy or vascular disorder. Moreover, it is extremely rare in the very young without risk factors. This paper presents a patient with ischemic colitis associated with heat stroke and rhabdomyolysis after intense exercise under high-temperature conditions. A 20-year-old man presented with mental deterioration after a vigorous soccer game for more than 30 minutes in sweltering weather. He also presented with hematochezia with abdominal pain. The laboratory tests revealed the following: AST 515 U/L, ALT 269 U/L, creatine kinase 23,181 U/L, BUN 29.1 mg/dL, creatinine 1.55 mg/dL, and red blood cell >50/high-power field in urine analysis. Sigmoidoscopy showed ischemic changes at the rectum and rectosigmoid junction. A diagnosis of ischemic colitis and rhabdomyolysis was made, and the patient recovered after conservative and fluid therapy. This case showed that a diagnosis of ischemic colitis should be considered in patients who present with abdominal pain and bloody diarrhea after intense exercise, and appropriate treatment should be initiated immediately.

Aortoesophageal fistula (AEF) is a rare and potentially fatal disease that causes massive gastrointestinal bleeding. Therefore, early diagnosis and treatment are essential to prevent mortality. Controlling the massive bleeding is the most important aspect of treating AEF. The traditional surgical treatment was emergent thoracotomy, but intraoperative or perioperative mortality was high. We report a case of a patient presenting with hematemesis who was successfully treated by a staged treatment, in which bridging thoracic endovascular aortic repair was followed by delayed surgical repair of the esophagus and aorta.

Acquired hemophilia is a rare, potentially life-threatening disease that usually remains under-recognized especially in a primary setting; thus, diagnosing this disease is very challenging. Given its prevalence in elderly patients, awareness and diagnosis of this condition in the aging population (particularly those with unexplained bleeding or prolonged activated partial thromboplastin time) should be improved and better managed by the clinicians. Early diagnosis and prompt treatment are usually effective in preventing the adverse outcomes of this disease. In this report, we discuss a case of an elderly patient with acquired hemophilia who initially presented with swelling of his lower left limb. The diagnosis of acquired hemophilia was made a month after the appearance of symptoms. Early diagnosis with proper treatment could have been provided to this patient, if the initial assessment had been thoroughly conducted.
