METHODS: Consecutive patients hospitalized for acute ischemic stroke between September 2010 and June 2013 were studied prospectively(n = 482; 40.2% males, age 78.8 ± 6.7 years). T2 DM was defined as self-reported T2 DM or antidiabetic treatment. Stroke severity was evaluated with the National Institutes of Health Stroke Scale(NIHSS) score at admission. The outcome was assessed with the modified Rankin scale(m RS) score at discharge and with in-hospital mortality. Adverse outcome was defined as m RS score at discharge ≥ 2 or in-hospital death. The length of hospitalization was also recorded.RESULTS: T2 DM was present in 32.2% of the study population. Patients with T2 DM had a larger waist circumference, higher serum triglyceride and glucose levels and lower serum high-density lipoprotein cholesterol levels as well as higher prevalence of hypertension, coronary heart disease and congestive heart failure than patients without T2 DM. On the other hand, diabetic patients had lower low-density lipoprotein cholesterol levels and reported smaller consumption of alcohol than non-diabetic patients. At admission, the NIHSS score did not differ between patients with and without T2DM(8.7 ± 8.8 and 8.6 ± 9.2, respectively; P = NS). At discharge, the m RS score also did not differ between the two groups(2.7 ± 2.1 and 2.7 ± 2.2 in patients with and without T2 DM, respectively; P = NS). Rates of adverse outcome were also similar in patients with and without T2DM(62.3% and 58.5%, respectively; P = NS). However, when we adjusted for the differences between patients with T2 DM and those without T2 DM in cardiovascular risk factors, T2 DM was independently associated with adverse outcome [relative risk(RR) = 2.39; 95%CI: 1.21-4.72, P = 0.012]. Inhospital mortality rates did not differ between patients with T2 DM and those without T2DM(9.0% and 9.8%, respectively; P = NS). In multivariate analysis adjusting for the difference in cardiovascular risk factors between the two groups, T2 DM was again not associated with in-hospital death. CONCLUSION: T2 DM does not appear to affect ischemic stroke severity but is independently associated with a worse functional outcome at discharge.展开更多

Methods A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ≥ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage. Results The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of 〈 30 U/L, 30-50 U/L and ≥ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively （P 〈 0.01）. The age-sex and multivariable adjusted odds ratios （95% confidence intervals） of poor prognosis comparing the top group （≥ 50 U/L） with the lowest group （〈 30 U/L） were 5.76 （2.74-12.13）, 6.64 （2.05-21.52）, and 6.36 （1.92-21.02）. A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers. Conclusion Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.展开更多

DNA methylation is involved in the pathogenesis and prognosis of stroke. However, the effect of DNA methylation on stroke at high levels of inflammation is unclear. In this study, we constructed a hyperinflammatory cerebral ischemia mouse model and investigated the effect of hypomethylation and hypermethylation on the functional outcome. We constructed a mouse model of transient middle cerebral artery occlusion and treated the mice with lipopolysaccharide to induce a hyperinflammatory state. To investigate the effect of DNA methylation on stroke, we used small molecule inhibitors to restrain the function of key DNA methylation and demethylation enzymes. 2,3,5-Triphenyltetrazolium chloride staining, neurological function scores, neurobehavioral tests, enzyme-linked immunosorbent assay, quantitative reverse transcription PCR and western blot assay were used to evaluate the effects after stroke in mice. We assessed changes in the global methylation status by measuring DNA 5-mc and DNA 5-hmc levels in peripheral blood after the use of the inhibitor. In the group treated with the DNA methylation inhibitor, brain tissue 2,3,5-triphenyltetrazolium chloride staining showed an increase in infarct volume, which was accompanied by a decrease in neurological scores and worsening of neurobehavioral performance. The levels of inflammatory factors interleukin 6 and interleukin-1 beta in ischemic brain tissue and plasma were elevated, indicating increased inflammation. Related inflammatory pathway exploration showed significant overactivation of nuclear factor kappa B. These results suggested that inhibiting DNA methylation led to poor functional outcome in mice with high inflammation following stroke. Further, the effects were reversed by inhibition of DNA demethylation. Our findings suggest that DNA methylation regulates the inflammatory response in stroke and has an important role in the functional outcome of hyperinflammatory stroke.展开更多

Decompressive Hemicraniectomy has been utilized to treat brain swelling and mass effect secondary to these infarctions in an attempt to improve functional outcome. <strong>Aim: </strong>To evaluate the functional outcome of decompressive hemicraniectomy in management of malignant MCA infarctions. <strong>Methods: </strong>The study included 30 patients with malignant MCA infarctions operated upon by decompressive hemicraniectomy and duroplasty with pericranium or fascia lata graft in the period from June 2016 to January 2019. Pre-operative neurological condition, associated morbidity, location and extent of the infarction were assessed. Surgery was performed within 48 hours of the onset of stroke or 12 hours within deterioration of conscious level. Pre-operative CT scan as well as sequential post-operative CT was done. Functional outcome was assessed by the modified Rankin Scale (mRS) at the time of discharge and 3 months following surgery. <strong>Results: </strong>The study included 18 males and 12 females with a mean age of 54.7 years. The pre-operative GCS was <8 (5 - 7) in 11 patients and 8 or higher (8 - 13) in 19 patients. Good functional outcome (mRS 0 - 3) was achieved in 13 (43.3%) cases while poor outcome (mRS 4 - 5) occurred in 8 (26.7%) cases and mortality (mRS 6) occurred in 9 (30%) cases. <strong>Conclusion:</strong> Decompressive hemicraniectomy improves functional outcome in cases of malignant MCA infarction. Pre-operative GCS, age, volume of infarction, degree of midline shift, timing of surgery and associated morbidity are the most important factors affecting the outcome.展开更多

The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.展开更多

The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square ort-test.Results:During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (allp > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients.Conclusion:Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.展开更多

We want to find the factors which can predict the final functional outcomes of these cases. Methods： All patients who presented to Accident and Emergency Department （ED） of the National Cheng Kung University Hospital from 1st January 2005 to 31th December 2013 with a hanging injury were included in this study. All cases were divided into good outcome group and bad outcome group according to Glasgow Outcome Scale （GOS）. Data was analyzed by Mann-Whitney test and chi-square test. Results： Glasgow Coma Scale （GCS） 〈 3, pupil dilation and no pupillary light reflex both at the scene and ED were the factors to indicate poor functional outcome. Out-hospital cardiac arrest （OHCA）, acidosis （pH 〈 Z2） and the need for intubation once arriving at ED were also related to poor functional outcome. OHCA cases all had poor functional outcome, Conclusion： GCS, pupil size, pupiUary light reflex, OHCA and acidosis are useful as prognostic factors. GCS= 3 lead to a very poor outcome. However, the functional outcome seems good in patients with GCS〉3. There parameters can help to predict the outcome before treatment.展开更多

Evidences support that thrombolysis is associated to a better functional outcome but not to intact cognition after subacute stroke.The purpose of this study is to compare cognition and functional capacity,6-10 months ...Evidences support that thrombolysis is associated to a better functional outcome but not to intact cognition after subacute stroke.The purpose of this study is to compare cognition and functional capacity,6-10 months after stroke,in patients treated with thrombolysis with rt-PA(tissular plasminogen activator)and those who were not.From October 2008 to March 2010,15 patients treated with thrombolysis with rt-PA and 30 patients who did not receive this treatment,underwent an extensive neuropsychological assessment and answered questionnaire about functionality.General cognitive performance,measured through the mean score of each cognitive domain,showed impairment with z score〉-1.50.Functional capacity was verified using PFAQ(Pfeffer Functional Activities Questionnaire)relative to instrumental activities of daily living.Five or more points in PFAQ demonstrated functional impairment.Continuous variables were analyzed by students't-test and categorical ones by Chi-square Cognitive deficits were present in 20%of all subjects.In the group who received treatment with thrombolysis with rt-PA,46.7%had language impairment,33.3%had visuospatial impairment,and 26.7%had visual memory impairment.This group presented 20%of patients with functional impairment.General cognitive performance(p 0.624)and functional capacity(p=0.664)showed no difference between groups.There was a statistically significant difference between groups concerning neglect(p=0.004)and sustained visual attention(p=0.028)Findings suggest that patients who received thrombolysis presented less neglect and less visual attention deficits but did not show better general cognitive functioning or functional capacity.展开更多
文摘BACKGROUND The posterior cruciate ligament(PCL)is vital for regulating posterior tibial translation in relation to the femur,which is critical for knee stability.PCL tears are infrequently isolated in knee injuries;however,the absence of the PCL results in abnormal knee kinematics,which may cause injuries to other ligaments.The ideal tendon source for PCL reconstruction is still a subject of debate.AIM To evaluate the results of employing the peroneus longus tendon(PLT)in PCL reconstruction.METHODS A comprehensive search was conducted to identify relevant randomized controlled trials and retrospective observational studies discussing the outcomes of using the PLT for PCL reconstruction.Studies published up to August 2024 were searched across multiple databases,including PubMed,EMBASE,Scopus,Web of Science,Cochrane Library,and Google Scholar.Full texts of the selected articles were retrieved,reviewed,and independently assessed by the investigators.Discrepancies were resolved by consensus,with any remaining disagreements being arbitrated by a third author.RESULTS This meta-analysis included five studies on PLT use for PCL reconstruction:(1)Four prospective studies with 104 patients;and(2)One retrospective study with 18 patients.Most studies followed up participants for 24 months,while one had a shorter follow-up of 18 months.Lysholm and modified cincinnati scores improved by pooled means of 32.2(95%CI:29.3-35.1,I2=0%)and 31.1(95%CI:27.98-34.22,I2=0%),respectively.Postoperative American Orthopaedic Foot and Ankle Society and Foot and Ankle Disability Index scores were 94.5(I2=61.5%)and 94.5(I2=80.09%),respectively.Single-hop and triple-hop test scores averaged 95.5(95%CI:94.5-96.5)and 92.4(95%CI:91.9-92.9)respectively.No significant differences were observed in thigh circumference at 10 cm and 20 cm between the injured and healthy sides.CONCLUSION Evidence supports PLT autografts for PCL reconstruction,improving knee function and patient outcomes.Larger randomized trials are needed to confirm efficacy and compare graft options.
文摘BACKGROUND Total knee arthroplasty(TKA)is a widely used treatment for advanced knee osteoarthritis;however,the incidence of failures requiring revision surgery is increasing.Identifying the causes of TKA failure and assessing the outcomes of revision procedures are essential for improving patient care.We hypothesized that infection and aseptic loosening are the primary causes of TKA failure and that revision TKA(rTKA)significantly enhances functional outcomes.AIM To examine the primary causes of TKA failure and evaluate the functional outcomes following rTKA.METHODS This descriptive study was conducted at the Department of Orthopedic Surgery,Civil Hospital,Bahawalpur,from April to September 2024.A total of 118 patients undergoing rTKA for failed primary TKA were included.Data on demographics,causes of failure,and surgical details were collected.Functional outcomes were evaluated using the Knee Society Score and Visual Analog Scale before and six months after surgery.Statistical analysis was performed using SPSS version 25.0,with statistical significance set at P<0.05.RESULTS The leading causes of TKA failure were infection(45.8%),aseptic loosening(44.1%),and periprosthetic fractures(10.2%).The rTKA significantly improved knee function,with the mean Knee Society Score increasing from 39.43±6.18 to 78.91±6.17(P<0.001).Pain levels decreased substantially,with the mean Visual Analog Scale scores reducing from 7.99±1.37 to 1.42±1.17(P<0.001).No significant differences in outcomes were observed between single-stage and two-stage revision procedures.CONCLUSION Infection and aseptic loosening are the predominant causes of TKA failure.The rTKA effectively enhances knee function and alleviates pain,offering significant benefits to patients.
文摘BACKGROUND Radial head fractures constitute approximately one-third of all elbow fractures,significantly impacting the young and active population.While open reduction and internal fixation is the preferred treatment for displaced fractures,its high complication rate in comminuted fractures has led to the increasing use of radial head arthroplasty(RHA).RHA provides improved functional outcomes with fewer complications,yet its long-term efficacy remains a topic of debate.AIM To evaluate the functional outcomes of patients undergoing RHA with a modular metallic prosthesis for comminuted Mason type III and IV radial head fractures.METHODS A prospective and retrospective hospital-based study was conducted at Dayanand Medical College and Hospital,Ludhiana over 32 months(January 2021-August 2023).A total of 26 patients with Mason type III and IV fractures were included,with six retrospective and 20 prospective cases.Functional outcomes were assessed using the Mayo Elbow Performance Score(MEPS),elbow range of motion,pain via Visual Analog Scale,and activities of daily living at immediate postoperative,three-month,and six-month follow-ups.RESULTS MEPS at 6 months follow up for 4 cases(15.38%)had good scores,and 22 cases(84.62%)had excellent scores,with a mean±SD of 97.31±6.67.Comparisons showed significant improvement from immediate post-operative to 3 months(P<0.0001),from immediate post-operative to 6 months(P<0.0001),and between 3 months and 6 months(P<0.0001).None of the patients had elbow instability after radial head replacement and 22 cases(84.62%)had no complications,while 3 cases(11.54%)had a stiff elbow,and 1 case(3.85%)had heterotopic ossification.CONCLUSION RHA is an effective treatment for comminuted radial head fractures,providing stable elbow function with minimal complications.
文摘AIM: To assess whether ischemic stroke severity and outcome is more adverse in patients with type 2 diabetes mellitus(T2DM). METHODS: Consecutive patients hospitalized for acute ischemic stroke between September 2010 and June 2013 were studied prospectively(n = 482; 40.2% males, age 78.8 ± 6.7 years). T2 DM was defined as self-reported T2 DM or antidiabetic treatment. Stroke severity was evaluated with the National Institutes of Health Stroke Scale(NIHSS) score at admission. The outcome was assessed with the modified Rankin scale(m RS) score at discharge and with in-hospital mortality. Adverse outcome was defined as m RS score at discharge ≥ 2 or in-hospital death. The length of hospitalization was also recorded.RESULTS: T2 DM was present in 32.2% of the study population. Patients with T2 DM had a larger waist circumference, higher serum triglyceride and glucose levels and lower serum high-density lipoprotein cholesterol levels as well as higher prevalence of hypertension, coronary heart disease and congestive heart failure than patients without T2 DM. On the other hand, diabetic patients had lower low-density lipoprotein cholesterol levels and reported smaller consumption of alcohol than non-diabetic patients. At admission, the NIHSS score did not differ between patients with and without T2DM(8.7 ± 8.8 and 8.6 ± 9.2, respectively; P = NS). At discharge, the m RS score also did not differ between the two groups(2.7 ± 2.1 and 2.7 ± 2.2 in patients with and without T2 DM, respectively; P = NS). Rates of adverse outcome were also similar in patients with and without T2DM(62.3% and 58.5%, respectively; P = NS). However, when we adjusted for the differences between patients with T2 DM and those without T2 DM in cardiovascular risk factors, T2 DM was independently associated with adverse outcome [relative risk(RR) = 2.39; 95%CI: 1.21-4.72, P = 0.012]. Inhospital mortality rates did not differ between patients with T2 DM and those without T2DM(9.0% and 9.8%, respectively; P = NS). In multivariate analysis adjusting for the difference in cardiovascular risk factors between the two groups, T2 DM was again not associated with in-hospital death. CONCLUSION: T2 DM does not appear to affect ischemic stroke severity but is independently associated with a worse functional outcome at discharge.

文摘Objective We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population. Methods A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ≥ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage. Results The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of 〈 30 U/L, 30-50 U/L and ≥ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively （P 〈 0.01）. The age-sex and multivariable adjusted odds ratios （95% confidence intervals） of poor prognosis comparing the top group （≥ 50 U/L） with the lowest group （〈 30 U/L） were 5.76 （2.74-12.13）, 6.64 （2.05-21.52）, and 6.36 （1.92-21.02）. A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers. Conclusion Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.

文摘Inflammation is closely related to stroke prognosis, and high inflammation status leads to poor functional outcome in stroke. DNA methylation is involved in the pathogenesis and prognosis of stroke. However, the effect of DNA methylation on stroke at high levels of inflammation is unclear. In this study, we constructed a hyperinflammatory cerebral ischemia mouse model and investigated the effect of hypomethylation and hypermethylation on the functional outcome. We constructed a mouse model of transient middle cerebral artery occlusion and treated the mice with lipopolysaccharide to induce a hyperinflammatory state. To investigate the effect of DNA methylation on stroke, we used small molecule inhibitors to restrain the function of key DNA methylation and demethylation enzymes. 2,3,5-Triphenyltetrazolium chloride staining, neurological function scores, neurobehavioral tests, enzyme-linked immunosorbent assay, quantitative reverse transcription PCR and western blot assay were used to evaluate the effects after stroke in mice. We assessed changes in the global methylation status by measuring DNA 5-mc and DNA 5-hmc levels in peripheral blood after the use of the inhibitor. In the group treated with the DNA methylation inhibitor, brain tissue 2,3,5-triphenyltetrazolium chloride staining showed an increase in infarct volume, which was accompanied by a decrease in neurological scores and worsening of neurobehavioral performance. The levels of inflammatory factors interleukin 6 and interleukin-1 beta in ischemic brain tissue and plasma were elevated, indicating increased inflammation. Related inflammatory pathway exploration showed significant overactivation of nuclear factor kappa B. These results suggested that inhibiting DNA methylation led to poor functional outcome in mice with high inflammation following stroke. Further, the effects were reversed by inhibition of DNA demethylation. Our findings suggest that DNA methylation regulates the inflammatory response in stroke and has an important role in the functional outcome of hyperinflammatory stroke.
文摘<strong>Introduction:</strong> Malignant middle cerebral artery (MCA) infarction is a devastating entity that is associated with up to 80% mortality. Decompressive Hemicraniectomy has been utilized to treat brain swelling and mass effect secondary to these infarctions in an attempt to improve functional outcome. <strong>Aim: </strong>To evaluate the functional outcome of decompressive hemicraniectomy in management of malignant MCA infarctions. <strong>Methods: </strong>The study included 30 patients with malignant MCA infarctions operated upon by decompressive hemicraniectomy and duroplasty with pericranium or fascia lata graft in the period from June 2016 to January 2019. Pre-operative neurological condition, associated morbidity, location and extent of the infarction were assessed. Surgery was performed within 48 hours of the onset of stroke or 12 hours within deterioration of conscious level. Pre-operative CT scan as well as sequential post-operative CT was done. Functional outcome was assessed by the modified Rankin Scale (mRS) at the time of discharge and 3 months following surgery. <strong>Results: </strong>The study included 18 males and 12 females with a mean age of 54.7 years. The pre-operative GCS was <8 (5 - 7) in 11 patients and 8 or higher (8 - 13) in 19 patients. Good functional outcome (mRS 0 - 3) was achieved in 13 (43.3%) cases while poor outcome (mRS 4 - 5) occurred in 8 (26.7%) cases and mortality (mRS 6) occurred in 9 (30%) cases. <strong>Conclusion:</strong> Decompressive hemicraniectomy improves functional outcome in cases of malignant MCA infarction. Pre-operative GCS, age, volume of infarction, degree of midline shift, timing of surgery and associated morbidity are the most important factors affecting the outcome.
文摘Giant cell tumor of the bone(GCTB)is a benign,locally aggressive neoplasm that is relatively rare,with a propensity to result in progressive bone destruction,and is associated with a high risk of recurrence.There is no widely held consensus regarding its ideal treatment.Worldwide,there are varying techniques ranging from intralesional curettage to resection of the lesion,supplemented with combinations of numerous adjuncts and fillers,depending on the resected amount and integrity of bone,as well as the preference of the surgeon.This was a cross-sectional study that included 20 patients who underwent limb salvage surgery for giant cell tumor of the bone of the lower extremities from January 2009 to February 2020 at two tertiary hospitals.The mean follow-up period was 37.3 months(SD=2.84).The extended curettage(EC)group had a mean Musculoskeletal Tumor Rating Scale(MSTS)score of 28.18(SD=7.51)which is considered as an excellent outcome,while the resection(RS)group had an mean MSTS score of 19.67(SD=11.02),which is considered as a good outcome.EC resulted to a total of eight complications(47%),while RS had one complication(33%).Prevalence of recurrence was noted to be 11.75%among those who underwent EC,while no recurrence was noted among those in the RS group.Use of bone cement as a filler was noted to have less recurrence as compared with the use of bone grafts,however were both were noted to result in excellent functional outcomes.Despite the prevalence of complications and recurrence of GCTB of the salvaged extremity in those who underwent EC,there is still report of excellent functionality.It is hence important to disclose all these possible outcomes and to stress the importance of compliance to follow-up for monitoring of these events.
文摘Objective: Radical cystectomy(RC)is a standard treatment for localized muscle invasive bladder cancer and high-risk or very high-risk non-muscle invasive bladder cancer not responding to adequate endovesical therapy.In women,traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall,often resulting in sexual disorders.Vaginal-sparing techniques have been developed to improve functional outcomes.The present study explores the safety and the functional outcome of vaginal-sparing techniques.Methods: We retrospectively analyzed all consecutive female patients undergoing robot-assisted RC(RARC)with neobladder diversion between October 2017 and February 2022.The indications for vaginal-sparing RC were absence of tumor on bladder neck or urethra and no sign of infiltration of posterior bladder wall at the preoperative MRI.Functional results were evaluated with the aid of five questions out of the Bladder Cancer Index questionnaire.Complications were reported according to the Clavien–Dindo classification and cancer control was evaluated by recurrence-free and cancer-specific survival.Results: A total of 22 female patients underwent RARC with neobladder diversion.Neoadjuvant chemotherapy was given in 17(77%)cases.Clavien–Dindo grades III–IV complications occurred in four(18%)cases.After a mean follow-up of 29(interquartile range 16–44)months,six(27.3%)patients developed distant metastases,and one(4.5%)woman loco-regional relapse.Sexual-sparing surgery was performed in 19(86%)patients,and in the others the anterior vaginal wall was resected,but neobladder was still performed.During daytime,no patients reported total incontinence and 73%(11/15)reported total continence or only occasional leaks.Sexual results showed that seven of 15(47%)women regained sexual activity after surgery,with a quality reported as“good”or“very good”in 40%of all 19 cases.Conclusion: RARC in female with anterior vaginal wall preservation is feasible.The approach showed a good safety profile,with satisfying results on continence and sexual activity.Sexual-sparing approaches should be carried out after correct patient selection.
文摘BACKGROUND Post-stroke depression(PSD)is a common and debilitating condition affecting stroke survivors,significantly impacting their recovery and overall quality of life.AIM To assess the effects of early PSD screening on functional outcomes,quality of life,and mortality.METHODS From an initial pool of 1065 articles,6 studies met the inclusion criteria and were selected for analysis.Functional outcomes were measured using the functional independence measure(FIM).RESULTS The analysis revealed a significant improvement in FIM scores for a PSD scree-ning group compared to controls[standardized mean difference(SMD)=8.90,95%confidence interval(CI):4.65-13.15,P<0.01].Quality of life was assessed using the Stroke-Specific Quality of Life Scale,with the screening group showing significantly higher scores(SMD=20.83,95%CI:15.27-26.38,P<0.01).Mortality analysis indicated a reduction in five-year mortality rates for the PSD screening group.CONCLUSION Early PSD screening enhances functional recovery,improves quality of life,and reduces mortality rates in stroke survivors.Thus,integrating PSD screening into routine stroke care improves long-term outcomes for patients.
文摘Introduction: The management of fractures of the tibia shaft is an important aspect of orthopaedic care, and the selection of the surgical method for fixation can substantially impact patient outcomes. The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.
文摘Purpose:To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures.Methods:A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square ort-test.Results:During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (allp > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients.Conclusion:Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

文摘Purpose:Previous studies have confirmed that Achilles tendon occurs Achilles thickening after repair surgery of the rupture.Although this mechanism has been elucidated in the laboratory,there are few reports on its impact on clinical function.We designed a retrospective study to investigate the Achilles thickening after Achilles tendon rupture repair and its correlation between the elasticity and postoperative function.Methods:In this retrospective analysis,patients who underwent surgical treatment for acute Achilles tendon rupture from April 2016 to April 2020 were included.All the patients were regularly followed up at 3 months,1 year,and 2 years after surgery.American Orthopaedic Foot Ankle Surgeon(AOFAS)scale and Leppilahti score were used to evaluate functional outcomes.Achilles elasticity was measured by ultrasound shear wave of elasticity.Achilles thickening was calculated as maximal transverse and longitudinal diameter in cross-sectional plane of magnetic resonance scan.Sample t-tests was used for different follow-up periods.Correlation between Achilles thickening and other factors were analyzed using Pearson's method.p<0.05 indicates a statistically significant difference.Results:AOFAS scale and Leppilahti score at 1 year were significantly higher than at 3 months postoperatively(both p<0.001).These functional scales were also improved at 2-year follow-up significantly(both p<0.001).The dorsiflexion difference showed gradually recovery in each follow-up period(t=-17.907,p<0.001).The elasticity of the Achilles appeared to continuously decreases during the postoperative follow-up period in all position sets(p<0.001).In thickening evaluation,the cross-sectional area of the thickest plane of Achilles was significantly higher at 1 year postoperatively(310.5±25.2)mm^(2)than that at 3 months postoperatively((278.0±26.2)mm^(2),t=-8.219,p<0.001)and became thinner in 2-year magnetic resonance scan((256.1±15.1)mm^(2),t=16.769,p<0.001).The correlations between Achilles thickening,elasticity,and functional outcome did not show statistical significance(p>0.05)in every follow-up period.Conclusion:Achilles tendon thickens after surgery in the 1st year,but begins to gradually return to thinning about 2 years after surgery.There was no significant correlation between the increase and decrease of thickening and the patients'clinical function scores,Achilles elasticity,and bilateral ankle dorsiflexion difference.
文摘Purpose： Suicide becomes a serious problem in today＇s society and hanging is a common method of suicide. We want to find the factors which can predict the final functional outcomes of these cases. Methods： All patients who presented to Accident and Emergency Department （ED） of the National Cheng Kung University Hospital from 1st January 2005 to 31th December 2013 with a hanging injury were included in this study. All cases were divided into good outcome group and bad outcome group according to Glasgow Outcome Scale （GOS）. Data was analyzed by Mann-Whitney test and chi-square test. Results： Glasgow Coma Scale （GCS） 〈 3, pupil dilation and no pupillary light reflex both at the scene and ED were the factors to indicate poor functional outcome. Out-hospital cardiac arrest （OHCA）, acidosis （pH 〈 Z2） and the need for intubation once arriving at ED were also related to poor functional outcome. OHCA cases all had poor functional outcome, Conclusion： GCS, pupil size, pupiUary light reflex, OHCA and acidosis are useful as prognostic factors. GCS= 3 lead to a very poor outcome. However, the functional outcome seems good in patients with GCS〉3. There parameters can help to predict the outcome before treatment.
文摘Background and Objectives:Sarcopenia is prevalent in patients with stroke.However,the relationship between sarcopenia and poor functional outcome of patients with acute stroke remains unknown.A systematic review and meta-analysis was performed to evaluate the above association.Methods and Study Design:Observational studies which evaluated the influence of sarcopenia on functional outcome in patients with acute stroke were retrieved by search the PubMed,Embase,Cochrane Library,and Web of Science databases.A poor functional outcome was defined as modified Rankin scale(mRS)of two or more points during follow-up.Two authors independently collected the data of study characteristics and outcomes.A random-effects model was used to pool the results via incorporating the influence of possible between-study heterogeneity.Results:Nine datasets from seven cohort studies contributed to the meta-analysis.A total of 1774 patients with stroke were included,and 481(27.1%)of them had sarcopenia.Compared to patients without sarcopenia,those with sarcopenia were associated with a higher risk of poor functional outcome during follow-up duration up to 6 months after stroke onset(odds ratio:2.42,95%confidence interval:1.76 to 3.33,p<0.001)with mild heterogeneity(I^(2)=23%).Subgroup analyses according to study design(prospective versus retrospective),sex of the patient,type of stroke(ischemic or mixed),diagnostic methods for sarcopenia,follow-up duration and cutoff scores for mRS showed consistent results(p for subgroup analyses all>0.05).Conclusions:Sarcopenia may be associated with poor functional outcome in patients with acute stroke.

文摘BACKGROUND The morbidity and burden of knee osteoarthritis affecting millions of lives worldwide has created a constant pursuit in finding the ideal treatment for knee osteoarthritis.There has been a paradigm shift in the surgical treatment of osteoarthritis ever since the initial description of Volkmann’s tibial osteotomy.This review focuses on one such recent procedure,the proximal fibular osteotomy(PFO)for medial compartment knee osteoarthritis.This review encompasses the history,evidence,risk factors,outcomes and technical considerations of PFO.AIM To understand the evidence and its techniques,and whether this could be an alternative solution to the problem of knee osteoarthritis in the developing world.METHODS The phrases“proximal fibular osteotomy”and“knee osteoarthritis”were searched(date of search December 20,2019)on PubMed to identify articles evaluating the biomechanical and clinical outcomes of PFO in patients with knee osteoarthritis.A total of 258 were retrieved.After reviewing the summary of the texts,22 articles written in English were marked for abstract review.Articles that were case studies or cadaver experiments were excluded.The abstracts of the remaining articles were read,and only those that focused on the history,outcomes of case studies and technical considerations of PFO were included in the review.A total of 12 articles were included in this review.RESULTS At least six studies reported improvement in the visual analogue scale(VAS)from the average preoperative VAS score[6.32,95%confidence interval(CI)=(4.05,8.59)]to average postoperative VAS score[1.23,95%CI:(-1.20,3.71)],which was statistically significant.Similarly,the American Knee Society Score(KSS)functional score improved from an average preoperative KSS functional score[43.11,95%CI:(37.83,48.38)]to postoperative KSS functional score[66.145,95%CI:(61.94,70.35)],which was statistically significant.The femorotibial angle improved by around 7º,and the hip knee ankle angle improved by around 6º.CONCLUSION With the existing data,it seems that PFO is a viable option for treating medial joint osteoarthritis in selected patients.Long term outcome studies and progression of disease pathology are some of the important parameters that need to be addressed by use of multicenter randomized controlled trials.
文摘BACKGROUND Treatments involving stem cell(SC)usage represent novel and potentially interesting alternatives in facial nerve reanimation.Current literature includes the use of SC in animal model studies to promote graft survival by enhancing nerve fiber growth,spreading,myelinization,in addition to limiting fibrotic degeneration after surgery.However,the effectiveness of the clinical use of SC in facial nerve reanimation has not been clarified yet.AIM To investigate the histological,neurophysiological,and functional outcomes in facial reanimation using SC,compared to autograft.METHODS Our study is a systematic review of the literature,consistently conducted according to the preferred reporting items for systematic reviews and meta-analyses statement guidelines.The review question was:In facial nerve reanimation on rats,has the use of stem cells revealed as effective when compared to autograft,in terms of histological,neurophysiological,and functional outcomes?Random-effect meta-analysis was conducted on histological and neurophysiological data from the included comparative studies.RESULTS After screening 148 manuscript,five papers were included in our study.43 subjects were included in the SC group,while 40 in the autograft group.The meta-analysis showed no significative differences between the two groups in terms of myelin thickness[CI:-0.10(-0.20,0.00);I^(2)=29%;P=0.06],nerve fibers diameter[CI:0.72(-0.93,3.36);I^(2)=72%;P=0.6],compound muscle action potential amplitude[CI:1.59(0.59,3.77);I^(2)=89%;P=0.15]and latency[CI:0.66(-1.01,2.32);I^(2)=67%;P=0.44].The mean axonal diameter was higher in the autograft group[CI:0.94(0.60,1.27);I^(2)=0%;P≤0.001].CONCLUSION The role of stem cells in facial reanimation is still relatively poorly studied,in animal models,and available results should not discourage their use in future studies on human subjects.
文摘BACKGROUND The goal of treatment for pediatric idiopathic clubfoot is to enable the patient to comfortably walk on his or her soles without pain.However,currently accepted treatment protocols are not always successful.Based on the abnormal bone alignment reported in this disease,some studies have noted a correlation between radiographic characteristics and outcome,but this correlation remains debated.AIM To assess the correlation between immediately postoperative radiographic parameters and functional outcomes and to identify which best predicts functional outcome.METHODS To predict the outcome and prevent early failure of the Ponseti’s method,we used a simple radiographic method to predict outcome.Our study included newborns with idiopathic clubfoot treated with Ponseti’s protocol from November 2018 to August 2022.After Achilles tenotomy and a long leg cast were applied,the surgeon obtained a single lateral radiograph.Radiographic parameters included the tibiocalcaneal angle(TiCal),talocalcaneal angle(TaCal),talofirst metatarsal angle(Ta1st)and tibiotalar angle(TiTa).During the follow-up period,the Dimeglio score and functional score were examined 1 year after surgery.Additionally,recurring events were reported.The correlation between functional score and radiographic characteristics was analyzed using sample and multiple logistic regression,and the optimal predictor was also identified.RESULTS In total,54 feet received approximately 8 manipulations of casting and Achilles tenotomy at a mean age of 149 days.The average TiCal,TaCal,Ta1st,and TiTa angles were 75.24,28.96,7.61,and 107.31 degrees,respectively.After 12 mo of follow up,we found 66%excellent-to-good and 33.3%fair-to-poor functional outcomes.The Dimeglio score significantly worsened in the poor outcome group(P value<0.001).Tical and TaCal showed significant differences between each functional outcome(P value<0.05),and the TiCal strongly correlated with outcome,with a smaller angle indicating a better outcome,each 1 degree decrease improved the functional outcome by 10 percent.The diagnostic test revealed that a TiCal angle of 70 degrees predicts an inferior functional outcome.CONCLUSION The TiCal,derived from lateral radiographs immediately after Achilles tenotomy,can predict functional outcome at 1 year postoperatively,justifying its use for screening patients who need very close follow-up.
文摘Evidences support that thrombolysis is associated to a better functional outcome but not to intact cognition after subacute stroke.The purpose of this study is to compare cognition and functional capacity,6-10 months after stroke,in patients treated with thrombolysis with rt-PA(tissular plasminogen activator)and those who were not.From October 2008 to March 2010,15 patients treated with thrombolysis with rt-PA and 30 patients who did not receive this treatment,underwent an extensive neuropsychological assessment and answered questionnaire about functionality.General cognitive performance,measured through the mean score of each cognitive domain,showed impairment with z score〉-1.50.Functional capacity was verified using PFAQ(Pfeffer Functional Activities Questionnaire)relative to instrumental activities of daily living.Five or more points in PFAQ demonstrated functional impairment.Continuous variables were analyzed by students't-test and categorical ones by Chi-square Cognitive deficits were present in 20%of all subjects.In the group who received treatment with thrombolysis with rt-PA,46.7%had language impairment,33.3%had visuospatial impairment,and 26.7%had visual memory impairment.This group presented 20%of patients with functional impairment.General cognitive performance(p 0.624)and functional capacity(p=0.664)showed no difference between groups.There was a statistically significant difference between groups concerning neglect(p=0.004)and sustained visual attention(p=0.028)Findings suggest that patients who received thrombolysis presented less neglect and less visual attention deficits but did not show better general cognitive functioning or functional capacity.
