Objective To study the sonographic features of mammary sclerosing adenosis (SA) and evaluate the diagnositic value of ultrasound. Methods Thirty-ifve patients with pathologically conifrmed SA in Ruijin Hospital from May 2009 to August 2013 were retrospectively analyzed. The Breast Imaging Reporting and Data System (BI-RADS) lexicon was introduced to describe the lesions. The diagnostic sensitivity was analyzed. Results The main sonographic ifndings of SA could be characterized into three types:(1) malignancy-looking nodule type (typeⅠ) (34%, 12/35). (2) benignity-looking nodule type (typeⅡ) (43%, 5/35). (3) architectural disorder type (typeⅢ) (23%, 8/35). Lack of blood supply has the greatest value in differential diagnosis among all sonographic features. The diagnositic sensitivity in typeⅠ, typeⅡ, typeⅢwere 0 (0/12), 93%(14/15), and 75%(6/8) respectively. The general sensitivity was only 57%(20/35). Conclusions There are no typical sonographic features in mammary sclerosing adenosis. Ultrasound doctors should improve their knowledge about this disease.

Objective: To evaluate the feasibility and efficacy of naked-eye assessment (NA) of ultrasound-guided fine needle aspiration cytology(US-FNAC) smears, which was performed by a trained non-cytological physician. Methods: A total of 290 smears of FNAC in 143 thyroid nodules were used to evaluate the value of NA by an assistant with more than two years experience of intervention with ultrasound guidance. NA results such as the background of smear (bloody/non-bloody), thickness (thick/thin), as well as the contents (granulated/non-granulated) were recorded. The correlation between NA and cytological results was analyzed. Number of cells under microscopy, the non-diagnostic rate, and the significance between benignity and malignancy with different features of specimens were compared. Results: There was no significant difference between the NA background and cytological findings(P=0.707, 0.200, 0.705, respectively). There was significance in number of cells, non-dianostic rate between thick and thinner specimens (P=0.000, 0.001, respectively). However, there was no significance in benignity and malignancy between thick and thinner specimens (P=0.385). There was significance in cytology results between the granulated and non-granulated smears(all P=0.000). The difference was found in 51.1% of the smears with granulates were malignancy in cytology. While 77.8% of the non-granulated smears were ultimately diagnosed as benignity. Conclusions The NA could be performed by a trained non-cytological physician and contribute to preliminary predictions of cytology effect.

Objective:To explore the predictive value of pre-treatment platelet-to-albumin ratio (PAR) in short-term prognosis of endoscopic treatment for cirrhosis with esophageal and gastric variceal bleeding(EGVB).Methods:By retrospective analysis method, the clinical data of 195 cirrhotic patients with EVGB from January 2019 to April 2022 treatment at Bengbu First People′s Hospital were collected and analyzed. The PAR was calculated according to platelet count and albumin. The independent risk factors that affecting 6-week rebleeding and death were analyzed by univariate and multivariate Cox regression, the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of PAR for rebleeding and death, and Kaplan-Meier survival analysis was used to evaluate the rebleeding rate and survival rate of patients with different PAR ratios.Results:Among 195 patients, 36 patients were rebleeding and 159 patients were non-rebleeding within 6 weeks; while 15 cases died and 180 cases survived. The platelet count, PAR in the rebleeding group were lower than those in the non-rebleeding group, the direct bilirubin, triglyceride, alanine transaminase, prothrombin time and mortality in the rebleeding group were higher than those in the non-rebleeding group: 74.0(66.5, 88.8) × 10 9/L vs. 98.0(85.0, 111.0)×10 9/L, 2.48(2.18, 2.78) vs. 3.35(2.81, 4.04), 18.5(14.0, 23.8) μmol/L vs. 16.0(11.0, 20.0) μmol/L, (4.73 ± 2.52) mmol/L vs. (3.94 ± 1.65) mmol/L, 36.0(27.0, 46.0)U/L vs. 21.0(13.3, 33.0)U/L, (14.78 ± 1.63) s vs. (13.47 ± 0.87) s, 36.11%(13/36) vs. 1.26%(2/159), there were statistical differences ( P<0.05). Cox multivariate regression showed that PAR, alanine transaminase were the independent risk factors for the rebleeding ( P<0.05), PAR was the independent risk factor for the death within 6 weeks ( P<0.05). The area under the curve (AUC) of PAR for predicting 6-week rebleeding and death was 0.876, 0.776, the cut-off was 2.94, 2.71, the specificity was 69.8%, 72.2%, the sensitivity was 94.4%, 73.3%, respectively. According to the cut-off of PAR to predict rebleeding, the 6-week rebleeding rate in the PAR≤2.94 group was higher than that in the PAR>2.94 group ( χ2 = 36.88, P<0.01). According to the cut-off of PAR to predict death, the 6-week mortality rate in the PAR≤2.71 group was higher than in the PAR>2.71 group ( χ2 = 16.44, P<0.01). Conclusions:PAR can be used as a predictor for rebleeding and death within 6 weeks of EGVB in cirrhotic patients.

Objective:To evaluate an effective manner to replace the drainage tube due to drainage complications during the irrigation treatment of abdominal infection after pancreaticoduodenectomy (PD).Methods:Clinical data of 39 patients with abdominal infection after PD due to drainage complications who were successfully treated by replacement of the drainage tubes with continued flushing in the Department of Hepatobiliary Surgery, Yuncheng Central Hospital Affiliated to Shanxi Medical University from August 2020 to August 2023 were retrospectively analyzed, including 23 males and 16 females, aged (54.8±9.6) years. According to the fashion of tube replacement, patients were divided into the observation group ( n=21), in which a flushing tube was placed through the original abdominal drainage tube sinus tract combined with external negative pressure suction; and the control group ( n=18), in which two parallel drainage tubes were placed through the original abdominal drainage tube sinus tract for flushing and drainage. The two groups were compared in terms of indicators before tube replacement, including the primary tumor classification, incidence of pancreatic fistula and biliary fistula after PD, complications of abdominal drainage, time from the surgery to tube replacement; and indicators after tube replacement, including total hospital stay, hospitalization cost, continuous abdominal lavage time, fever and elevated white blood cell count, number of dressing changes, etc. Results:There were no significant difference in the primary tumor classification, incidence of pancreatic fistula and biliary fistula after PD, complications of abdominal drainage, and time from PD to tube replacement between the two groups before tube replacement (all P>0.05). After tube replacement, the total hospitalization time(32.7±1.9 vs 44.7±14.5, d), hospitalization cost (67 604±16 052 vs 91 845±19 826, yuan), continuous abdominal lavage time [4.0 (3.0, 5.0) vs 9.0 (8.0, 10.8), d], fever [23.8% (5/21) vs 55.6% (10/18)] and leukocytosis rate [28.6% (6/21) vs 66.7% (12/18)], and times of dressing change times [10.0 (7.0, 13.0) vs 22.0 (18.2, 27.0)] of the observation group were lower than those of the control group (all P<0.05). Conclusion:Inserting a flushing tube through the sinus tract of original abdominal drainage tube combined with external negative pressure drainage is an effective way to manage the abdominal infection after PD surgery due to drainage complications, featuring good irrigation and drainage, short irrigation time, and early control of the abdominal infection.

Solitary cervical submental nodule is a relatively rare case in clinical procedure and prone to miss diagnosis.Differential diagnosis with various head and neck diseases is necessary.This article reported a case of solitary cervical submental metastasis of papillary thyroid carcinoma received in the department of surgery,Civil Aviation Shanghai Hospital,Ruijin Gubei Branch,Shanghai Jiao Tong University School of Medicine.The patient came to the outpatient clinic for treatment due to"consciously larger submental tubercle than before".Ultrasound examination revealed suspicious lesions in both the thyroid and submental regions.Ultrasound-guided final needle aspiration biopsy diagnosed as malignant tumor.Surgical resection was performed and the central group lymph nodes dissected Pathological examination confirmed papillary thyroid carcinoma with solitary submental metastasis.This article reported the clinical diagnosis and treatment of this case,in order to improve the disease recognition for clinicians,and make differential diagnosis with other rare neck diseases,and avoid missing diagnoses.
