Pseudogout and gout are common types of inflammatory joint disease in the elderly. However, the existence of both in a single joint in a patient is relatively rare. This case report describes an interesting case of a 42-year old man who presented with simultaneous gout and pseudogout in the knee joint, diagnosed via polarised light microscopy. There was no radiographic evidence of pseudogout. This case report serves to illustrate the need to actively exclude concomitant pseudogout, especially in patients suffering from recurrent attacks of gout.

Objective: To explore the value of Hisense computer-assisted surgical systems (CAS) for precise surgery of pediatric solid pseudopapillary tumor. Methods: A total of 5 cases with pancreatic solid pseudopapi-llary tumor who were admitted at the Affiliated Hospital of Qingdao University from June 2015 to September 2018 were adopting.Upper abdominal 64-slice dynamic enhanced computed tomography (CT) scan was performed.3D models were created by computer-assisted surgery systems.Based on 3D model, surgical planning, preoperative simulated tumor resection, intraoperative assisted guidance were performed.Operation time, intraoperative blood loss volume, blood transfusion rate were analyzed. Results: Hisense CAS three-dimensional reconstruction could clearly show the adjacent relationship between pancreas, tumor and peripheral vascular organs.According to the preoperative virtual resection, pancreatic tumor resection was more accurate.Postoperative pathological results were solid pseudopapillary tumor of the pancreas.Among them, 2 tumors were located in the head of the pancreas, 1 case was located in the pancreatic neck, and 2 cases in the tail of the pancreas.The operation time was 150-360 min, with an average of 279 min.The average intraoperative blood loss was 40 mL, of which the minimum amount of bleeding was 5 mL, and the blood transfusion rate was 40%(2/5 cases). Surgical tumor removal was achieved successfully in 5 cases.All children were followed up for 6 months to 3 years, and no recurrence or metastasis was observed. Conclusions Three-dimensional reconstruction of computer-assisted surgery system can clearly show the adjacent relationship between tumor and surroun-ding vascular organs, and help to make the best surgical plan before surgery to improve the accuracy and safety of the operation.

OBJECTIVE: To investigate the prehospital intervention based on emergency medical services (EMS) in patients with acute ischemic stroke (AIS) for door-to-needle time (DNT) with intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) impact. METHODS: 112 emergency patients receiving rt-PA intravenous thrombolysis admitted to the First Hospital of Qinhuangdao City based on EMS from June 2016 to December 2017 were enrolled. According to whether or not to receive prehospital interventions, patients were divided into prehospital intervention group (n = 42) and routine treatment group (n = 70). Both groups followed the general principles of first aid, including assessment and support of the airway, respiration, and circulation, and blood glucose, electrocardiogram, and dynamic vital signs were monitored. Based on the general principle of EMS, first-aid personnel in the prehospital intervention group screened suspected acute stroke patients requiring prehospitalization according to Los Angeles prehospital stroke screening table (LAPSS), and established fluid ways, and got blood samples to evaluate rt-PA intravenous thrombolysis and risks. Factors influenced DNT compliance were analyzed through multivariate Logistic regression, which included the education level of the patient, whether there were risk factors related to cerebrovascular disease (hypertension, coronary heart disease, diabetes), visit time, National Institute of Health stroke scale (NIHSS) score, whether received EMS intervention or not. The average DNT, DNT ≤ 60 minutes compliance rate, communication time, and decision time for thrombolysis were compared between the two groups. NIHSS score was used to evaluate the effective rate of thrombolysis for 7 days. The modified Rankin score (mRs) was used to evaluate the neurological function after 3 months of thrombolysis (a mRs score of 0-2 was defined as a good nerve function). RESULTS: Univariate analysis showed that the DNT of patients with NIHSS score > 5 was significantly shorter than those with NIHSS score ≤ 5, and DNT in patients received EMS intervention was significantly shorter than the non-receiver; but education level, visiting time, and risk factors associated with cerebrovascular disease had nothing to do with DNT. Multivariate Logistic regression analysis showed that NIHSS score and EMS intervention were the influencing factors of DNT compliance [NIHSS score: odds ratio (OR) = 0.452, 95% confidence interval (95%CI) = 0.162-1.263, P = 0.030; EMS intervention: OR = 3.077, 95%CI = 1.260-7.514, P = 0.014]. Compared with conventional treatment group, DNT of intravenous thrombolytic in prehospital intervention group was significantly shortened (minutes: 62.00±11.07 vs. 78.03±21.04), DNT ≤ 60 minutes compliance rate was significantly increased [35.7% (15/42) vs. 12.9% (9/70)], communication time [minutes: 4 (3, 6) vs. 6 (5, 9)] and decision-making thrombolytic time (minutes: 5.81±2.48 vs. 6.70±2.15) were significantly shortened, the differences were statistically significant (all P < 0.05). The 7-day effective rate in the prehospital intervention group [33.3% (14/42) vs. 14.3% (10/70), χ² = 5.657, P = 0.017] and the 3-mouth good rate of nerve function [38.1% (16/42) vs. 14.3% (10/70), χ² = 10.759, P = 0.001] were significantly higher than those in the conventional treatment group. CONCLUSIONS Prehospital interventions based on EMS can shorten DNT of intravenous thrombolysis in the patients with AIS, improve treatment efficiency, and improve prognosis.
