Objective To investigate the relationship between early fluid management and the conversion rate to surgery in patients with sever acute pancreatitis( SAP) .Methods The patients with SAP admitted in ICU in West China Hospital from July 2005 to June 2010 were retrospectively analyzed. They were divided into four groups according to the quartile of the accumulated fluid balance in the first three days after admission in ICU( lt; 25% , 25% ～50% , 50% ～75% , and gt; 75% , respectively) . The major demographic data, clinical characteristics, mortality, and conversion rate to surgery were evaluated respectively. Results 208 patients were enrolled. For each quartile, the conversion rate to surgery decreased at first, and then increased along with the increase of the accumulated fluid balance. Significant difference existed between the second quartile with the lowest conversion rate to surgery and other three quartiles ( P lt; 0. 05) . Differences were also found in mortality and the score of acute physiology and chronic health evaluation Ⅱ( APACHEⅡ) on 24th and 48th hour between the first three quartiles and the last quartile with the highest mortality and APACHⅡ score( P lt;0. 05) . However, sex ratio, age, Ranson criteria, and the score of sequential organ failure assessment( SOFA) did not have significant differences among each quartile( P gt; 0. 05) . Conclusion Fluid management in early stage can influence conversion rate to surgery and mortality in patients with SAP.
Objective To investigate early clinical manifestations of osteogenic sarcoma to help establishment of an early diagnosis of the disease.Methods A total of 92 patients with osteogenic sarcoma in the extremities were admitted to our hospital from April 1984 to October 2002. Of the 92 patients, 71 (42 males and 29 females; averaged age 17.4 years, range 666 years; illness course 1-28 weeks) had a complete record of their medical history and examination. From their first medical visits, we obtained their clinical symptoms, physical sings, diagnoses, and duration of the delayed diagnoses. The patients were pathologically confirmed as having osteogenic sarcoma in the extremities, with the lesions located in the distal femur in 38 patients, proximal tibia in 22, proximal femur in 3, proximal fibula in 3, proximal humerus in 2, distal tibia in 2, and distalradius in 1. Results Of the 71 patients, 70 had a local pain and/or a palpable mass, 37 had a persistent pain with no difference between day and night, 23 had an intermittent pain, and 11 had a nocturnal pain. Of the 71 patients, 42 had an initial pain related to trauma, and 3 of the 42 patients had a pathologic fracture. The patients with the local mass had a delayed diagnosis of osteogenic sarcoma with a delayed duration of 1-14 weeks, averaged 4 weeks; however, the patients without the local mass had a delayed diagnosis of this disease, with a delayed duration of 3-30 weeks averaged 14 weeks. In the patients undergoing an X-ray examination at the first medical visit, the duration of the delayed diagnoses was 1-20 weeks, averaged 8 weeks, but in the patients without an X-ray examination at first, the duration was 4-30 weeks, averaged 16 weeks. Conclusion Intermittent and persistent pains and local masses are the most characteristic clinical manifestations in the early stage of osteogenic sarcoma. A history of trauma often helps to make a diagnosis of the disease. Carefulclinical examination and observation should be given to adolescent patients whohave a recurrent pain around the joint.
Objective To investigate the risk factors of early allograft dysfunction (EAD) following C-Ⅱ donation after cardiac death (DCD) liver transplantation. Methods The data of 46 donors and recipients of C-ⅡDCD liver transplantation between March 2012 and August 2015 were retrospectively analyzed. The baseline data such as democracy, death cause, donor warm ischemic time (DWIT) and cold ischemic time (CIT) in EAD group and the non-EAD group (control group) was compared, and whether these factors were risk factors of EAD was investigated by univariate and multivariate analyses. Statistical cut-off values for significant factors of the unfavorable analysis were defined by receiver operating characteristics (ROC) analysis. The 6-month and 1-year graft survival rate were compared. Results The EAD group had a longer DWIT compared with the group [(17.6±4.7) and (12.7±6.2) minutes, P=0.009]; meanwhile, the EAD group had a longer CIT compared with the control group [(13.7±4.7) and (11.0±3.5) hours, P=0.020]. The other factors in both groups showed no statistical significance (P>0.05). The ROC curve revealed the cut-off values of DWIT and CIT were 17.50 minutes [area under the curve (AUC)=0.713, P=0.020] and 9.85 hours (AUC=0.723, P=0.015), respectively. The multivariate logistic regression analysis showed the DWIT [odds ratios (OR)=1.340, 95% confidence interval (CI)(1.042, 1.654), P=0.008] and CIT [OR=1.396, 95% CI (1.075, 1.698), P=0.015] were all independent risk factors of EAD. The 6-month and 1-year graft survival rate of the EAD group and the control group was 85.7% vs. 92.3% (P=0.607) and 71.4% vs. 84.6% (P=0.587), respectively. Conclusions EAD may occured in C-Ⅱ donors with DWIT≥17.50 minutes or CIT≥9.85 hours in DCD liver transplantation. The livers can be used as a resource for clinical use and also have a good outcome.
Carbapenemase producing Enterobacteriaceae (CPE) has emerged as a significant global public health challenge and placing infected patients at risk of potentially untreatable infections. When resistance to carbapenems occurs, there are often few alternative treatments available. Numerous international guidelines have performed systematic and evidence review to identify new strategies to prevent the entry and spread of CPE in healthcare settings. Several key strategies have been shown to be highly effective. Firstly a new strategy that is proven to be effective is the early identification of the CPE carrier patients through active surveillance cultures. While waiting for the screening results, suspected CPE carriers will be put on preemptive isolation in single room and healthcare worker will at the same time practice contact precautions. The active surveillance culture and prompt preemptive isolation will limit the entry and spread of CPE from getting into hospital. Secondly, it is of utmost importance to incorporate enforcement of the basic infection prevention and control best practices in the hospital including, full compliance to hand hygiene, appropriate use of personal protective equipment, execute antibiotic stewardship program to control abuse of antibiotics, effective environmental cleaning and decontamination, staff education and feedback, as well as surveillance of healthcare-associated infections. Such a holistic approach has been shown to be effective in inhibiting CPE from gaining foothold in the hospital.
ObjectivesTo systematically review the differences of operative outcomes between early surgery and delayed surgery in multiple ligament injury of knee joint (MLIK) patients.MethodsPubMed, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data and VIP databases were searched to collect cohort studies about operative outcomes of different surgery times in MLIK patients from inception to September 23rd, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 8 cohort studies involving 153 early and 90 delayed operatively treated patients were included. The results of meta-analysis showed that: compared with delayed surgery, early surgery received higher Lysholm score (MD=7.52, 95%CI 2.00 to 13.04, P=0.008) and superior IKDC score rate (OR=2.97, 95%CI 1.51 to 5.84, P=0.002). There were no significant differences in Tegner score (MD=–0.08, 95%CI –1.07 to 0.92, P=0.88) and ROM (MD=4.08, 95%CI –2.38 to 10.55, P=0.22) between two groups. The main adverse reactions of MLIK included neurovascular injury, deep venous thrombosis of lower extremities, common peroneal nerve injury, tourniquet paralysis and limited joint activity. Early surgery had a lower incidence of complications than delayed surgery (7.1% vs. 30%).ConclusionThe current evidence shows that early surgery can receive higher Lysholm score and superior IKDC score rate in treatment of MLIK, and have a lower incidence of complications. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To evaluate the usefulness of minimal incision technique in total knee arthroplasty (TKA) by comparing the early compl ications after minimal incision TKA and those after traditional incision. Methods From May 2004 to July 2005, 38 patients (46 knees) underwent TKA using the minimal incision technique (minimal incision group), and 43 patients (54 knees) underwent TKA using the traditional incision technique at the same period (traditional incision group). The inimal incision group included 12 male patients (12 knees) and 26 female patients (34 knees), and their ages ranged from 52 to 76 years. Twenty-four patients (28 knees) had osteoarthritis and 14 patients (18 knees) had rheumatic arthritis. The varus deformity of the knee was found in 30 patients (34 knees) and valgus deformity was found in 8 patients (12 knees). TheAmerican Knee Society Score (AKSS) score was 37.5 ± 12.6, and the disease course was (7.5 ± 2.3) years. The raditional incision group included 15 male patients (19 knees) and 28 female patients (35 knees), and their ages ranged from 55 to 82 years. Thirtytwo patients (37 knees) had osteoarthritis and 11 patients (17 knees) had rheumatic arthritis. Varus deformity of the knee was found in 34 patients (41 knees) and valgus deformity was found in 9 patients (13 knees). The AKSS score was 31.1 ± 10.2, and the disease course was (10.1 ± 4.2) years. There were no statistically significant differences in the general data between two groups (P gt; 0.05). Results The incision length, the operation time and the drainage flow were (12.6 ± 1.2) cm, (95 ± 15) minutes and (650.1 ± 10.0) mL in the minimal incision group and (18.7 ± 2.3) cm, (63 ± 11) minutes and (300.0 ± 20.0) mL in the traditional incision group; showing statistically significant differences between two groups (P lt; 0.05). In the minimal incision group, 4 patients (4 knees) developed infections at the operated knees, including 2 early infection and 2 late infection, which were all cured by corresponding treatment. Deep vein thrombosis occurred in 1 patient on the third day after operation and was managed successfully by thrombolytic therapy. Cutaneous necrosis was found in 2 patients on the seventh and ninth postoperative day separately, which healed uneventfully after intensive local treatment. On the twelfth postoperative month, 1 patient had femoral fractured at the site of supracondylar region after a careless fall, but the prosthesis was stable. The fracture was fixed by a plate and healed uneventfully. In the traditional incision group, only 1 patient (1 knee) developed early infection at the operated knee on the tenth postoperative day, which was managed by corresponding treatment. And there were no periprosthetic fracture, cutaneous necrosis or deep vein thrombosis. The patients were followed up for (3.7 ± 0.4) years in the minimalincision group and (3.9 ± 0.6) years in the traditional incision group. At the latest follow-up, the AKSS scores were 78.2 ± 6.7 in the minimal incision group and 81.2 ± 7.3 in the traditional incision group, showing statistically significant ifferences (P lt; 0.05) when compared with those before operation and no statistically significant difference between two groups (P gt; 0.05). Conclusion Minimally invasive TKA has relatively higher compl ication rate than traditional incision. Strict patient inclusion criteria, competent surgery skill, proper instrument and intensive perioperative management are essential to success.
ObjectiveTo systematically review the short term and long term efficacy of early surgery for infective endocarditis (IE) patients. MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases for cohort studies concerning the efficacy of early surgery for IE patients from inception to October 2014. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsSixteen cohort studies including 8 141 patients were included. The results of meta-analysis showed that early surgery could reduce the short term mortality (OR=0.57, 95%CI 0.42 to 0.77, P=0.000 4) and long term mortality (OR=0.57, 95%CI 0.43 to 0.77, P=0.000 7) in IE patients. Subgroup analysis showed that early surgery could significantly reduce the short term mortality and long term mortality in patients with native valve endocarditis (NVE). ConclusionEarly surgery can reduce IE patients' short term mortality and long term mortality. Due to the limited quality and quantity of the included studies, more large-scale high-quality studies are needed to verify the above conclusion.
OBJECTIVE To introduce the technique of epiphysiolysis and epiphysis grafting in the treatment of early partial closure of the epiphysial plate in children, and evaluate its effect. METHODS Retrospective study was performed in 10 cases of cubitus varus and valgus, or genu varum and valgum due to early partial closure of the epiphysial plate, 6 cases received simple cuneiform osteotomy, and 4 cases received epiphysioloysis and epiphysis grafting. RESULTS Clinical outcoming after 6-month to 5-year’s follow-up showed 1 case deformity of recurrence and 2 cases of non-isometric limb after simple osteotomy, while no recurrence and isometric limb after epiphysiolysis and epiphysis grafting. CONCLUSIONEpiphysiolysis and epiphysis grafting may effectively prevent the recurrence of postoperative deformity, and restore the longitudinal growth of limb.
OBJECTIVE: To search for the operation timing and methods for obstetrical brachial plexus injury (OBPI). METHODS: Thirty-two children with upper OBPI were treated by microsurgical procedure from October 1997 to April 2001. The average age of patients was 10 months, ranged from 3 months to 24 months; of them, 19 were below 6 months while 13 were over 6 months. Surgical procedure included neurolysis(n = 12), coaptation after resection of the neuroma without function (n = 7), phrenic nerve transfer to anterior cord of upper trunk or musculocutaneous nerve (n = 7) and intercostal nerves transfer to musculocutaneous nerve(n = 6). The children underwent operation with microsurgical technique and 7/0 or 9/0 nylon was used for nerve suture. RESULTS: Thirty cases were followed up for 21 months postoperatively; the excellent and good rate was 76.7% (23/30). The results of the children under 6 months were better than those over 6 months. CONCLUSION: The microsurgical operation might be considered at the age of 3-6 month infants who had shown little or no improvement in elbow flexion. Neurolysis and nerve coaptation are superior to neurotization. The appropriate procedure should be selected according to the findings of exploration.
Objective To investigate the expression of cell division regulators p16, Rb and cyclin D1 in human early gasric carcinoma tissues and their role in tumor transformation and the correlation among p16, Rb and cyclin D1. MethodsA comparative study was carried out by using immuno-histochemical techniques between the paracarcinomatous intestinal metaplasia of 39 cases of early gatric carcinoma and the non-carcinomatous gastric mucosal intestinal metaplasia tissues of 34 cases.ResultsOver expression of cyclin D1 was determined in 33/39 carcinomatous samples(84.6%) and also in para-carcinomatous intestinal metaplasia tissues. p16 was undetectable in 12 of 39 samples. Interestingly, 15 of 26 Rb positive cancers had no or low p16,while 9 Rb negative cancers showed high levels of p16.Conclusion The over expression of cyclin D1 may be a common molecular abnormality and an early molecular event in early gastric carcinoma. Cyclin D1 over expression and Rb inactivation can co-exist in early gastric carcinoma. However, there is a reciprocity between Rb inactivation and p16 expression in early gastric carcinoma. Thus, abnormality in the negative feedback regulatory pathway of cyclin D1,Rb and p16 may be related to the tumorigenesis in early gastric carcinoma.
