ABSTRACT
Objective:To evaluate the risk factors of acute kidney injury (AKI) in patients with multiple wasp stings.Methods:Patients with multiple wasp stings were retrospectively enrolled in Hanzhong Central Hospital from September 2010 to November 2020. Based on whether the patients developed AKI, the patients were divided into AKI group and non-AKI group. The general characteristics and laboratory examinations between the two groups were compared. The logistic regression model was used to analyze the risk factors of AKI.Results:A total of 356 patients with multiple wasp stings were recruited in this study, with 196 males (55.1%). The age was 56.0(45.0, 64.0) years old. There were 59 patients (16.6%) with hypertension and 13 patients (3.6%) with diabetes. There were 51 patients (14.3%) in the AKI group and 305 patients (85.7%) in the non-AKI group. Baseline data and biochemical examinations indicated that the two groups showed significant differences in gender, age, sting sites (systemic or local), sting needles, proportions of gross hematuria, leukocyte count, hemoglobin, creatine kinase, alanine transaminase, aspartate aminotransferase, total bilirubin, proportions of urinary protein, and proportions of urine occult blood (all P<0.05). The multivariate logistic regression analysis results showed that the increasing number of sting needles (every 10 needles increase, OR=1.866, 95% CI 1.289-2.071, P=0.001), gross hematuria ( OR=9.770, 95% CI 2.586-36.910, P=0.001), decreasing hemoglobin (every 1 g/L increase, OR=0.016, 95% CI 0.001-0.355, P=0.009), increasing aspartate aminotransferase (every 100 U/L increase, OR=1.311, 95% CI 1.144-1.502, P<0.001), and increasing total bilirubin (every 10 μmol/L increase, OR=1.200, 95% CI 1.008-1.430, P=0.041) were independent influencing factors of AKI. Conclusions:The increasing number of sting needles, gross hematuria, decreasing hemoglobin, increasing aspartate aminotransferase, and increasing total bilirubin are independent risk factors of AKI in patients with multiple wasp stings.
ABSTRACT
Objective To explore the diagnostic value of 18F-FDG PET/CT in primary peritoneal papillary serous carcinoma (PPPSC).Methods Ten postmenopausal female cases of pathologically diagnosed PPPSC from March 2009 to October 2011 were retrospectively reviewed (age range:61-81 years,mean:(69.4±6.2) years).All cases underwent 18F-FDG PET/CT.The CT characteristics and SUVmax of lesions on PET images were analyzed.Serum CA125 levels were measured before or after PET/CT within one week.The patterns of PPPSC on PET/CT were compared with histopathological results.Linear correlation analysis was used to evaluate the correlation between the CA125 and the maximum SUVmax of lesions presented in parietal peritoneum,greater omentum or mesentery.Results The PET/CT uptake pattern of the 10 PPPSC cases was described as floccus,multi-nodular or cake-like in greater omentum (SUVmax =6.32±2.87),and as diffuse or localized nodules,or non-uniform strip-like thickening in 9 parietal peritoneum and 8 mesentery cases (SUVmax =5.96±2.14 and 5.70± 1.69,respectively).The most commonly involved sites were pelvic wall of peritoneum and mesentery of small intestine.All 10 cases had different degrees of ascites,mainly intrapelvic and perihepatic.Hypermetabolic ovarian enlargement (all ＜5 cm) was bilateral in 2 patients and right-sided in 1 patient.Four patients had retroperitoneal lymph node metastasis and others were found with punctate calcifications in metastatic lymph nodes,small pleural effusions,liver metastasis,as well as portal node metastasis.CA125 concentration was elevated in all cases ((51.25±26.40) ×104 U/L),but there was no significant correlation between CA125 and the maximum SUVmax of lesions found in parietal peritoneum,greater omentum or mesentery (r=0.05,P＞0.05).Conclusion 18F-FDG PET/CT could show the positions and metabolic status of PPPSC lesions.It may be an effective imaging modality in the diagnosis and assessment of PPPSC.
