Detection of Anterior Circulation Large Artery Occlusion in Ischemic Stroke Using Noninvasive Cerebral Oximetry.

BACKGROUND AND PURPOSE: Large artery occlusion (LAO) in ischemic stroke requires recognition and triage to an endovascular stroke treatment center. Noninvasive LAO detection is needed to improve triage. METHODS: Prospective study to test whether noninvasive cerebral oximetry can detect anterior circulation LAO in acute stroke. Interhemispheric ΔBrSO2 in LAO was compared with controls. RESULTS: In LAO stroke, mean interhemispheric ΔBrSO2 was -8.3±5.8% (n=19), compared with 0.4±5.8% in small artery stroke (n=17), 0.4±6.0% in hemorrhagic stroke (n=14), and 0.2±7.5% in subjects without stroke (n=19) (P<0.001). Endovascular stroke treatment reduced the ΔBrSO2 in most LAO subjects (16/19). Discrimination of LAO at a -3% ΔBrSO2 cut had 84% sensitivity and 70% specificity. Addition of the G-FAST clinical score (gaze-face-arm-speech- time) to the BrSO2 measure had 84% sensitivity and 90% specificity. CONCLUSIONS: Noninvasive cerebral oximetry may help detect LAO in ischemic stroke, particularly when combined with a simple clinical scoring system.

Comparative study in surgical outcome of intracapsular fracture neck of femur in active elderly patients treated with hemiarthroplasty with Austin Moore's and bipolar prosthesis.

Fracture neck of femur is most commonly encountered fractures in elderly population. Hemiarthroplasty is generally considered to be the treatment of choice in most active elderly patients. However, there is inadequate evidence to support the choice between unipolar or bipolar prosthesis. This study was conducted to analyze the outcome regarding pain, hip function, complication and acetabular erosion in patients randomly selected and treated with Austin Moore's or Bipolar hemiarthroplasty in our setup. The study included total of 40 patients (17 males and 23 females) with intracapsular neck of femur fractures with mean age of 67 years (55-85 years). 20 patients each were treated with Hemiarthroplasty using Austin Moore's and Bipolar prosthesis. The patients were followed up at intervals of 2 weeks, 6 weeks, 24 weeks and 1 year after the operation and evaluated clinically and radiologically. There were no significant differences between the groups regarding complication. The Harris hip score were 81.95% (SD - 2.99) in Austin Moore's hemiarthroplasty and 79.15% (SD - 2.94) in Bipolar hemiarthroplasty (p = 0.812), whereas acetabular erosion was 20.05% in Austin Moore's hemiarthroplasty and 5% in Bipolar hemiarthroplasty (p = 0.758) with no mortality seen during lyear follow up. The intracapsular neck of femur fracture in active elderly patients treated with Austin Moore's hemiarthroplasty had better outcome regarding pain and hip function whereas high acetabular erosion compared to patients treated with Bipolar hemiarthroplasty though the difference is statistically insignificant.

Diaphyseal femoral fractures in children treated with titanium elastic nail system.

Femur fractures are common long bone injuries in children which account for less than 2% of all paediatric fractures. Although these fractures are dramatic and disabling injuries for the child and parent, the good part is that they unite rapidly with minimal complications if aligned well. Various methods have been used successfully to treat these fractures, but they differ in their stability and potential for complications. The aim of our study was to see the outcome of titanium elastic nailing system in diaphyseal femoral fracture in children. The study included total of 30 children's (19 boys and 11 girls) of diaphyseal femoral fracture treated with titanium elastic nailing system and they were followed up at 2, 6, 12 and 24 weeks. The average duration of callus formation was 3.5 weeks with radiological union mean time of 9.5 weeks. Full weight bearing was possible in a mean time of 10 weeks. According to flynn's scoring criteria, excellent and good results were in 24 cases (80%) and 6 cases (20%) respectively. The nail irritation was present in 3 childrens and there was no post operative infection, physeal injury and implant failure. Titanium elastic nail is a safe and satisfactory mode of treatment and is relatively easy to perform in disphyseal fracture of femur in children. It avoids the chances of physeal injury, infection and offers rapid healing.

The treatment of trigger thumb in children: conservative or surgical?

The trigger thumb is an uncommon condition in infants and children which occurs due to pathology of flexor pollicis longus or A1 pulley. The objectives in our study were to determine the treatment outcome of trigger thumb. The study included total of 45 patients (24 males and 21 females) with trigger thumb. The mean age of onset was 28.5 months (3 months -7 years). There was overall success rate of 72.41% following conservative treatment and the success rate appears to be higher in the younger age group. The outcome of children who underwent surgery was 91.66% with recurrence rate of 8.33% and superficial wound infection rate of 4.16%. Our study suggests that surgery is not urgent, postponing surgery does not interfere with the result, trying conservative methods to get a higher chance of recovery is reasonable before the elective surgery. So conservative approach should be adopted in treating trigger thumb.

Outcome of pertrochantric fracture of the femur treated with proximal femoral locking compression plate.

Pertrochantric femoral fractures are one of the most common fracture in old patients with variety of complications. However fixing Pertrochantric femoral fractures properly is clinically challenging. We report the outcome of pertrochantric femoral fractures treated with Proximal Femoral Locking Compression Plate (PFLCP) using Minimal Invasive Percutaneous Plate Osteosynthesis (MIPPO) techniques which were evaluated clinically by Harris hip score and radiologically for a union at fracture site and implant related complication. The study included total of 33 patients (20 males and 13 females) with Pertrochantric femoral fractures. The mean ages of the patients were 57 years (23-88 years). Pertrochantric femoral fractures included both Intertrochantric and Subtrochantric femoral fractures. Patients were followed up at 2 weeks, 6 weeks, 3 months, 6 months and 1 year after the operation. Among the 33 patients, the union rate was 95% (31 patients). However there were 1 case of implant breakage and 1 case of non union. According to Harris Hip score the excellent and good results were 87.87% with no mortality during 1 year follow up period. The PFLCP can be feasible alternative to the treatment of Pertrochantric femoral fractures by providing biological healing and mechanical stability with limited occurrence of complications.
