Retrospective study comparing the effectiveness of preoperative autologous blood donation versus intra-operative blood saver systems in minimizing the need for allogeneic blood transfusion in scoliosis surgery. Between 2003–2009, 37 of the patients (4–33, mean age 20y) who underwent scoliosis surgery, were divided in two groups. The first group (20 patients, mean age 18.7y) underwent autologous blood predonation, prerequisities were body weight over 50 kgr and Hgb above 11 mg/dl. The second group (17 patients, mean age 21.5y) consisted of patients who did not meet the above prerequisities and blood saver was used intra-operatively. Duration of surgery and perioperative Haemoglobulin (Hgb) levels were recorded in both groups.AIM
MATERIALS – METHODS
Intra-articular shoulder pathology has been recognised in more detail following widespread use of shoulder arthroscopy. The purpose of this epidemiological study is to present the incidence and exact type of SLAP lesions in our operated population and to correlate them with the presence of other shoulder lesions. Between 2004 and 2010 425 patients underwent shoulder arthroscopy in our department (311 for rotator cuff tears or subacromial impingement, 102 for shoulder instability, 12 for SLAP lesions). Eighty-two SLAP lesions (19.2% overall) were recognized during these procedures. In 44 cases the lesion was SLAP type I (53.6%), in 10 type II (12.2%), in 1 type III (1.2%), in 1 type IV (1.2%), in 24 type V (29.26%) and finally in 2 type VI (2.43%). In more detail SLAP I lesions were associated in 8 patients with subacromial impingement syndrome, in 33 with RC tear and in 3 patients with anterior instability. Type II, III and IV were preoperatively diagnosed, while type V and VI lesions were found in patients with chronic anterior shoulder instability. SLAP lesions are diagnosed more accurately during shoulder arthroscopy rather than with plain shoulder MRI scan. In our study population only 12 cases were accurately diagnosed with a pre-operative MRI scan, while the remaining 70 cases were missed. Additionally, there was significant correlation between rotator cuff problems and SLAP I lesions, while chronic shoulder instability was associated with SLAP V and VI (25.4% of patients with instability). Shoulder arthroscopy not only has changed SLAP lesion diagnosis and treatment but also reveals the correlation of various SLAP lesion types with specific shoulder pathologies.
The SRS-22 is a valid instrument for the assessment of the health related quality of life of patients with Idiopathic scoliosis. The purpose of this study is to evaluate the reliability and validity of the adapted Greek version of the refined Scoliosis Research Society-22 Questionnaire. Following the steps of cross – cultural the adapted Greek version of the SRS-22 questionnaire and a validated Greek version of the SF-36 questionnaire were mailed to 68 patients treated surgically for Idiopathic Scoliosis with a mean age at the time of operation 16.2 years and a mean age at the time of evaluation 21.2 years respectively. A 2nd set of questionnaires was mailed in 30 patients within 30 days from the 1st set. Reliability assessment was determined by estimating Cronbach’s a and intraclass correlation coefficient (ICC) respectively. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36 questionnaire using Pearson’s Correlation Coefficient (r). The calculated Cronbach’s a of internal consistency for three of the corresponding domains (pain 0.85; mental health 0.87; self image 0.83) were very satisfactory and for two domains (function/activity 0.72 and satisfaction 0.67) were good. The ICC of all domains of SRS-22 questionnaire was high (ICC>
0.70). Considering concurrent validity all correlations demonstrated high correlation coefficient. The adapted Greek version of the SRS-22 questionnaire is valid and reliable and can be used for the assessment of the outcome of the treatment of the Greek speaking patients with idiopathic scoliosis
