Resumen:OBJECTIVES: To study the morphological characteristics of the injury caused by ox horn on human body and its injury mechanism, and to discuss the rules and characteristics of injury by ox horn and provide forensic evidences for identification of such cases. METHODS: The comparative analysis of position and morphological characteristics were performed by summarizing the data of 100 victims gored by ox accepted by Heilongjiang agricultural areas public security bureau during 2004-2014. RESULTS: The specific injuries only could be found at the contact positions such as thorax and abdomen, lower back and limbs of the victims gored by ox horn. Most of the skin wounds had the characteristics of sharp injuries, the bar-type injury by club which called "rail way bruise" was an obvious characteristic appeared on the soft tissue. CONCLUSIONS: Ox horn can cause non-specific injuries on thorax and abdomen, lower back and limbs of human body, which are similar with the characteristics of sharp injury and injury by club. Careful analyzation and identification should be performed on such injury in daily work.

Resumen:This study aims to investigate the efficacy of early rehabilitation therapy on the movement ability of hemiplegic lower extremity in patients with acute cerebrovascular accident (CVA).A total of 86 patients who suffered from acute CVA were selected and divided into 2 groups, according to random number tables: control group, and research group. Patients in the control group received routine primary therapy, while patients in the research group received rehabilitation based on the basic therapy. The recovery of hemiplegic limb movement ability and the improvement of daily living ability before and after treatment were evaluated using the simplified Fugl-Meyer assessment (FMA), neurologic deficit scale (NDS), and Barthel index (BI). After treatment, the clinical efficacy and satisfaction degree for treatment were compared.The FMA, NDS, and BI of patients in these 2 groups were distinctly ameliorated after treatment (P <.05). After treatment, the ameliorated degrees of FMA, NDS, and BI in the research group were obviously superior to those in the control group, and the differences were statistically significant (P <.05). The total efficacy and satisfaction degree in the research group were evidently higher than those in the control group after early rehabilitation therapy, and the differences were statistically significant (P <.05).Early rehabilitation therapy can significantly ameliorate the movement ability of hemiplegic lower extremity in patients with acute CVA. Its therapeutic effect is remarkable. Hence, it is worthy of popularizing in clinical practice.

Resumen:BACKGROUND AND PURPOSE: The Fugl-Meyer Assessment motor scale, Postural Assessment Scale for Stroke patients, and Barthel Index are widely used to assess patients' upper extremity and lower extremity motor function, balance, and basic activities of daily living after stroke, respectively. However, these 3 measures (72 items) require a great amount of time for assessment. Therefore, we aimed to develop an efficient test, the Functional Assessment of Stroke (FAS). METHODS: The FAS was constructed from 4 short-form tests of the Fugl-Meyer Assessment-upper extremity, Fugl-Meyer Assessment-lower extremity, Postural Assessment Scale for Stroke patients, and Barthel Index based on the results of Rasch analyses and the items' content. We examined the psychometric properties of the FAS, including Rasch reliability, concurrent validity, convergent validity, known-group validity, and responsiveness. RESULTS: The FAS contained 29 items (10, 6, 8, and 5 items for the 4 short-form tests, respectively). The FAS demonstrated high Rasch reliability (0.92-0.94), concurrent validity ( =0.90-0.97 with the original tests), convergent validity ( =0.62-0.94 with the 5-scale Fugl-Meyer Assessment), and known-group validity (significant difference in the FAS scores among 3 groups of disability levels; <0.001). In addition, the responsiveness of the FAS (standardized response mean=0.55-1.93) was similar or significantly superior to those of the original tests (standardized response mean=0.46-1.39). CONCLUSIONS: The FAS contains 29 items and has sufficient Rasch reliability, validities, and responsiveness. These findings support that the FAS is efficient for reliably and validly assessing upper extremity/lower extremity motor function, balance, and basic activities of daily living and for sensitively detecting change in those functions in patients with stroke.

Resumen:This study investigated the immediate and short-term effects of minimalist shoes (MS) and traditional running shoes (TRS) on vertical loading rates, foot strike pattern and lower limb kinematics in a group of habitual barefoot runners. Twelve habitual barefoot runners were randomly given a pair of MS or TRS and were asked to run with the prescribed shoes for 1 month. Outcome variables were obtained before, immediate after and 1 month after shoe prescription. Average and instantaneous vertical loading rates at the 1-month follow-up were significantly higher than that at the pre-shod session (P < 0.034, η > 0.474). Foot strike angle in the TRS group was significantly lower than that in the MS group (P = 0.045, η = 0.585). However, there was no significant time nor shoe effect on overstride, knee and ankle excursion (P > 0.061). Habitual barefoot runners appeared to land with a greater impact during shod running and they tended to have a more rearfoot strike pattern while wearing TRS. Lower limb kinematics were comparable before and after shoe prescription. Longer period of follow-up is suggested to further investigate the footwear effect on the running biomechanics in habitual barefoot runners.

Resumen:The purpose of the current study was to examine the effect of 6 weeks of whole body vibration training (WBVT) on body composition, muscle activity of the gastrocnemius and vastus lateralis, gastrocnemius muscle architecture (static and dynamic) and ground reaction forces (performance jump) during the take-off phase of a countermovement jump in young healthy adult males. A total of 33 men (23.31 ± 5.62 years) were randomly assigned to a whole body vibration group (experimental group, EG : n = 17; 22.11 ± 4.97 years) or a control group (CG: n = 16; 24.5 ± 6.27 years). The total duration of the intervention phase (WBVT) was 6 weeks with a frequency of 3 sessions per week. Statistically significant differences were observed (P ≤ 0.05) between pre- and post-test in the power peak (Δ 1.91 W · kg ; P = 0.001), take-off velocity (0.1 cm · s ; P = 0.002) and jump height (Δ 0.4 cm; P = 0.002) for EG . There were no statistically significant differences in any of the body composition and muscle architecture variables. Moreover, no significant differences were found between EG and CG nor changes in muscle activity during take-off phase of the gastrocnemius and vastus lateralis pre- versus post-training. This study suggests that a 6-week WBVT programme with increasing intensity improves jump performance but does not alter muscle activity nor muscle architecture in healthy young men.

Resumen:Revascularization after extremity vascular injury has long been considered an important skill among trauma surgeons. Increasingly, some trauma surgeons defer vascular repair in response to training or practice patterns. This study was designed to document results of extremity revascularization surgery to evaluate trauma surgeon outcomes and judicious referral of more complex injuries to vascular surgeons (VAS). The trauma registry of an urban level I trauma center was used to identify all patients from 2003 to 2013 who underwent an early (<24 hours) procedure for urgent management of acute injury to extremity vessels. Patients were managed by trauma (TRA) versus VAS based on the practice pattern of the on-call trauma surgeon. Injury and outcome variables were recorded. Of 115 patients, 84 patients were revascularized by trauma and 31 vascular surgeries. There was no difference in complication rates or frequency of any type of complication associated with repairs performed by VAS or TRA. There were similar rates between the two groups for patients with multiple injuries, such as venous, bone or tendon, and nerve injury to the affected extremity. One VAS patient and two TRA patients developed compartment syndrome. In appropriately selected patients, trauma surgeons achieve good outcomes after revascularization of injured extremities.

Resumen:RATIONALE: Purpura is a common dermatologic manifestation in Sjögren syndrome (SS). When a patient presents with sicca symptoms, the diagnosis of SS is not difficult. PATIENT CONCERNS: Here, we reported a case of a 52-year-old Chinese woman who initially presented with nonpalpable purpura on both lower extremities, and these lesions had developed soon after prolonged sitting. In the past 2 years, she had repeated cutaneous nonpalpable purpura 4 times. She had no sicca symptoms, dry eyes, or dry mouth. DIAGNOSES: Combining the laboratory findings, Schirmer test, and labial gland biopsy, primary SS was confirmed. INTERVENTIONS: The patient was placed on a trial of hydroxychloroquine (200 mg once daily). OUTCOMES: The purpura on both lower extremities had faded at the sixth day after onset and at the third day after hydroxychloroquine treatment. LESSONS: These case was not easy to diagnosis primary SS because she had no sicca symptoms. A patient with primary SS who initially presented with recurrent purpura associated with prolonged sitting. Prolonged sitting had been a possible aggravating factor for the cutaneous purpura of this patient with primary SS.

Resumen:Importance: Following clean (class I, not contaminated) surgical procedures, the rate of surgical site infection (SSI) should be less than approximately 2%. However, an infection rate of 12.2% has been reported following removal of orthopedic implants used for treatment of fractures below the knee. Objective: To evaluate the effect of a single dose of preoperative antibiotic prophylaxis on the incidence of SSIs following removal of orthopedic implants used for treatment of fractures below the knee. Design, Setting, and Participants: Multicenter, double-blind, randomized clinical trial including 500 patients aged 18 to 75 years with previous surgical treatment for fractures below the knee who were undergoing removal of orthopedic implants from 19 hospitals (17 teaching and 2 academic) in the Netherlands (November 2014-September 2016), with a follow-up of 6 months (final follow-up, March 28, 2017). Exclusion criteria were an active infection or fistula, antibiotic treatment, reimplantation of osteosynthesis material in the same session, allergy for cephalosporins, known kidney disease, immunosuppressant use, or pregnancy. Interventions: A single preoperative intravenous dose of 1000 mg of cefazolin (cefazolin group, n = 228) or sodium chloride (0.9%; saline group, n = 242). Main Outcomes and Measures: Primary outcome was SSI within 30 days as measured by the criteria from the US Centers for Disease Control and Prevention. Secondary outcome measures were functional outcome, health-related quality of life, and patient satisfaction. Results: Among 477 randomized patients (mean age, 44 years [SD, 15]; women, 274 [57%]; median time from orthopedic implant placement, 11 months [interquartile range, 7-16]), 470 patients completed the study. Sixty-six patients developed an SSI (14.0%): 30 patients (13.2%) in the cefazolin group vs 36 in the saline group (14.9%) (absolute risk difference, -1.7 [95% CI, -8.0 to 4.6], P = .60). Conclusions and Relevance: Among patients undergoing surgery for removal of orthopedic implants used for treatment of fractures below the knee, a single preoperative dose of intravenous cefazolin compared with saline did not reduce the risk of surgical site infection within 30 days following implant removal. Trial Registration: clinicaltrials.gov Identifier: NCT02225821.

Resumen:IMPORTANCE: Long-term outcomes of an interwoven nitinol stent design represent the best in class for treatment of lower limb arterial obstructive disease METHODS: The subjects were enrolled in an open single arm study comparing the outcomes to an FDA mandated objective performance goal (OPG). RESULTS: About 325 patients (264 intention-to-treat and 64 roll-in subjects) were enrolled. Mean follow-up period was 887+/- 352 days. Treated lesion lengths were 7.8 cm ± 4.3 cm in the trial with chronic total occlusions comprising 24.6% (65/264) of subjects. Freedom from clinically driven target lesion revascularization (CD-TLR) at 12 months was 89%, at 24 and 36 months it was 84% and 82% respectively. The difference in the 12 month CD-TLR was 7% at 36 months. The difference of clinically driven-TLR at 36 months in those subjects who received their stents deployed nominally in length, compressed or elongated (between -10% and +10% nominal length) had an impact on the CD-TLR. At 2 and 3 years, freedom from CD-TLR in minimal compression was 86.7%, and was 90.0% for moderate compression. In those stents deployed with minimal, moderate, or severe elongation (10-20%, 20-40%, or >40%, respectively) freedom from CD-TLR of 84.1%, 87.4%, and 77.0% respectively at 12 months. At 2 and 3 years, freedom from CD-TLR for moderate elongation was 81.8% and 78.2%, and for severe elongation was 63.4% and 42.3%, respectively. Fractures were distinctly uncommon with this stent with a single facture event in the 36 month follow-up period. DISCUSSION: The interwoven nitinol design stent is a stent that achieves an excellent primary patency but further maintains the durability of the stent through 36 months. Optimal stent deployment remains critical to the performance of this stent device and requires optimal vessel preparation. © 2017 Wiley Periodicals, Inc.

Resumen:The study examined the differences between boys and adults after an intense stretch-shortening cycle fatigue protocol on neuromechanical parameters of the lower limb. Thirteen boys (9-11 years old) and 13 adult men (22-28 years old) were tested for maximal isometric voluntary knee extension torque and drop jump (DJ) performance from 30 cm before and immediately after a fatigue protocol, consisted of 10 × 10 maximum effort vertical jumps. Three-dimensional kinematics, kinetics and electromyographic (EMG) parameters of the lower extremities muscles were recorded during DJs before and after the fatigue test. The results indicated that reduction in maximal isometric torque and jumping performance was significantly higher in adults compared to boys. Vertical ground reaction forces, contact time and maximum knee flexion increased in a greater extend in adults than in boys. In addition, preactivation, EMG agonist activity, knee joint stiffness and stretch reflex decreased more in adults than in boys at all the examined phases of jumping tasks. It is concluded that employed fatigue protocol induced acute reduction in performance and altered motor control during jumping in both age groups. However, the differences in the level of fatigue between the 2 groups could be attributed to neuromuscular, mechanical and kinematic parameters observed between groups.
