In Brief Study Design. A retrospective cohort study to identify rates and analyze the risk factors for postoperative spinal wound infection. Objective. To determine significant infection by comparing those patients who developed a with rest of cohort. Summary Background Data. surgical site (SSI) is common complication after surgery. SSI leads higher morbidity, mortality, healthcare costs. develop strategies reduce SSI, independent should be identified. Methods. The electronic patient record...
In order to identify the risk factors and incidence of post-operative spinal epidural haematoma, we analysed records 14 932 patients undergoing surgery between 1984 2002. Of these, 32 (0.2%) required re-operation within one week initial procedure had an International Classification Diseases (ICD)-9 code for haematoma complicating a (998.12). As controls, selected those who undergone equal complexity by same surgeon but not developed this complication. Risks identified before operation were...
Deep brain stimulation (DBS) of the ventral intermediate nucleus thalamus (VIM) has proven to be efficacious in treatment essential tremor (ET). The authors report on long-term follow-up a series patients treated at 1 institution by neurosurgeon.Thirty-four with ET received unilateral or bilateral VIM DBS. and handwriting components Fahn-Tolosa-Marin clinical rating scale were assessed pre- postoperatively. Visual analog scores for overall patient satisfaction control recorded. Stimulation...
Background: Coumadin is widely used in the elderly population. Despite its widespread use, little known about effect on outcome of traumatic brain-injured patients. This study was undertaken to describe outcomes such a cohort. Methods: Clinical material identified from Level I trauma center prospective head injury database, and database obtained American College Surgeons Committee Trauma Verification Review 1999 2002. Both databases contain many relevant variables, including age, sex,...
Descriptive, retrospective cohort analysis.To evaluate the presentation, etiology, and treatment of surgical site infections (SSI) after spinal surgery.SSI spine surgery is frequently seen. Small case control studies have been published reporting results options SSI. We performed this study to identify most common clinical laboratory presentation a SSI, seen infective organism, effectiveness current treatment.All patients who underwent at our institution for diagnosis other than infection...
Objectives To characterize the incidence, risk factors, and consequences of delirium in older adults undergoing spine surgery. Design Prospective observational study. Setting Academic medical center. Participants Individuals aged 70 surgery (N = 89). Measurements Postoperative severity were assessed using validated methods, including Confusion Assessment Method ( CAM ), for Intensive Care Unit, Delirium Rating Scale‐Revised‐98, chart review. Hospital‐based outcomes obtained from record...
Erythrocyte cell membranes undergo morphologic changes during storage, but it is unclear whether these are reversible. We assessed erythrocyte membrane deformability in patients before and after transfusion to determine the effects of storage duration reversible transfusion.Sixteen undergoing posterior spinal fusion surgery were studied. was compared between those who required moderate (≥ 5 units erythrocytes) received minimal (0-4 erythrocytes). Deformability measured samples drawn directly...
Background: The treatment of vertebral compression fractures with augmentation procedures is associated acute pain relief and improved mobility, but direct comparisons treatments are limited. Our goal was to compare the survival rates, complications, lengths hospital stay, charges, discharge locations, readmissions, repeat for Medicare patients new that had been acutely treated vertebroplasty, kyphoplasty, or nonoperative modalities. Methods: 2006 Provider Analysis Review File database used...
Background Surgical site infections (SSI) after spinal surgery increase morbidity, mortality, length of hospital stay, and costs. Most previously identified risk factors for these infections, such as severity illness procedure duration, are not amenable to intervention. This study sought identify modifiable associated with SSI surgery. Methods is a case-control including case identification review medical records. A total 104 patients were compared randomly selected control without in...
Severely obese patients who undergo orthotopic liver transplantation are likely to have higher morbidity, mortality, costs, and a lower long-term survival.This case-control study was done at university hospital. One hundred twenty-one consecutive underwent between 1994 1996 were studied. Severe obesity defined as body mass index (BMI) more than 95th percentile (>32.3 for women >31.1 men), moderate BMI 27.3 32.3 27.8 31.1 men. The outcome measures intraoperative complications, postoperative...

Forty 1 tournament-level tennis players with expert serve technique volunteered to have their evaluated determine relationships between anthropometric data, extremity strength, and functional velocity. All underwent a complete physical examination, video taped analysis, radar measurement of velocity, series upper strength measurements. Statistical analysis was performed which factors were related Statistically significant found be tween velocity several flexibility measure ments including...
Thirty elite tennis players were randomly assigned to three groups evaluate shoulder isokinetic internal and external rotation training: an concentric group, eccentric a control group with no training. Subjects tested before after training both concentrically eccentrically using dynamometer. Functional output was assessed by the average peak velocity of six maximal serves. The effect on serve endurance also assessed. Statisti cally significant strength gains (11 %) obtained in when com pared...
Background The treatment of type II superior labral anterior posterior (SLAP) lesions remains controversial. Many surgeons are reluctant to combine a SLAP repair with an acromioplasty for fear postoperative shoulder stiffness and poor clinical outcome. Hypothesis A done concomitantly may yield acceptable outcomes. Study Design Case series; Level evidence, 4. Methods We compared the results 50 patients who had either isolated (SLAP group, 34 patients) or combined (combined 16 patients)....
Recent literature indicates that females are more resistant to shock-, trauma-, and sepsis-induced immune dysfunction organ injury than males. Consequently, using trauma-hemorrhagic shock (T/HS) burn models, we tested whether the neutrophil response trauma occurred in a sexually dimorphic fashion and, if so, role of sex hormones. Neutrophil activation, as reflected by CD11b expression respiratory burst activity, was increased greater extent male rats female after T/HS or injury. Testosterone...
In Brief Study Design. Retrospective review. Objectives. To determine postoperative mortality after adult spinal deformity surgery. whether independent risk factors can predict mortality. Summary of Background Data. Although surgery is reported to range from 0.03% 3.52%, there a general paucity data on and its associated Methods. Three hundred sixty-one adults with underwent 407 corrective procedures. For patients who died within 30 days the procedure, following were examined if each could...
In Brief Study Design. Retrospective review. Objective. To determine the incidence and identify associated risk factors of pulmonary embolism (PE) in patients who receive pharmacologic thromboprophylaxis after adult spinal deformity surgery. Summary Background Data. The PE surgery is reported to be as high 2.2%. However, risks same patient population postoperative unknown.
