Spontaneous Subarachnoid Hemorrhage

Background: In evaluation of non-traumatic subarachnoid hemorrhage CT angiography (CTA) has 97-98% sensitivity and near 100% specificity. Objective: This study was conducted to evaluate the CTA findings of CT positive non traumatic subarachnoid hemorrhage. Methodology: This is an observational cross sectional study performed in Neurology department of National Institute of Neurosciences and Hospital, Dhaka over one year period (January 2019 to December 2019). Total 87 CT positive subarachnoid hemorrhage cases were purposively included in this study. All CT positive patients underwent CTA of Cerebral vessels for further evaluation. The angiography were evaluated by competent neuro-radiologists blinded about the study. Result: Among 87 patients, 40.2% were male and 59.8% were female. The average age was 53.33±11.1 years. Among the studied patient the source of bleeding was found 78.16% aneurysmal and 21.84% non-aneurysmal. 85.30% patients had single aneurysm and 14.70% had multiple aneurysm. The highest number of patient had Acom aneurysm (41.17%) followed by MCA (22.05%), ICA (13.23%), ACA (7.35%) and vertebral artery (1.14%) in order of frequency. Among the multiple aneurysm group most of the patients had combination of Acom, MCA and ICA aneurysm. Conclusion: From this study, we can conclude that CTA can be used as the primary diagnostic tool in evaluation of spontaneous SAH.

Abstract Background: Curved periacetabular osteotomy (CPO) was developed to treat acetabular dysplasia. Given that CPO can improve physical function in the early post-operative period, patients might be able to participate in sports activities post-operatively. Therefore, this study examined the post-operative sports activity participation and characteristics of acetabular dysplasia patients who have undergone CPO.Methods: A total of 52 patients who underwent CPO for acetabular dysplasia were given a questionnaire on pre- and post-operative sports activities; 43 patients responded. We surveyed patients’ sports activities, satisfaction, and physical function. Patients were divided according to whether they participated in sports activities after CPO. Physical function was compared before and after CPO.Results: The pre- and post-operative sports activity participation rates were 55.8% and 72.1%, respectively. Patients mostly performed low-impact sports activities. Moreover, patients who participated in sports activities post-operatively had smaller pre-operative range of motion of hip flexion and returned to full weight bearing earlier.Conclusions: Among acetabular dysplasia patients who underwent CPO, 72.1% participated in sports activities post-operatively. Post-operatively, patients participated not only in low-impact sports activities, but also in high-impact ones. These findings might be useful for advising patients who are concerned about participating in sports activities after CPO.

Background: Diameters of coronary artery aneurysms (CAAs) due to KD in the acute phase can strongly predict long-term prognosis of coronary artery lesions. Recently, Computed Tomography Angiography (CTA) has been used in the diagnosis of coronary artery lesion (CAL). Purpose: The purpose of this study was to determine whether measurements of coronary artery diameters by CTA using DSCT can be used instead of coronary angiograms (CAG) during cardiac catheterization. Methods: Twenty five pts (22 males and 3 females) with CAL due to KD were evaluated. Their ages ranged from 5 months to 38 years (median 11years). CTA was performed between July 2007 and July 2013, and CAG was done within one year. A prospective Electrocardiogram (ECG) -triggered CTA was performed on a DSCT (SOMATOM® Definition (from July 2007 to October 2009) or SOMATOM® Definition Flash (from October 2009 to July 2013); Siemens Healthcare, Germany). ECG-gated scans were performed in 19 cases and Flash Spiral scans in 6 cases. Two pediatric cardiologists measured the diameters of CAAs twice in each maximum intensity projection (MIP), curved multi planer reconstruction (MPR) and CAG. We measured 161 segments in total (segment1-3,5-7,11,13). Diagnostic accuracy was expressed as κ coefficient. A Bland-Altman analysis was also used to assess the inter-observer, intra-observer and inter-material agreement. Results: The visualization capability of coronary arteries was excellent. One segment was not visualized by CTA. Detection rate in CTA, comparing with CAG, was 99.7%, and the diagnostic quality of CTA was excellent (κ=0.93). Excellent inter-observer agreement for diameters of CAAs was obtained for MIP, MPR and CAG and for the intra-observer agreement. The inter-modality agreement was also excellent (MPR-CAG : y=0.9x+0.40, r=0.97 ,p<0.01 MIP-CAG : y=1.0x+0.1, r=0.94, p<0.01). We also studied the diameters in normal segments. We also obtained good correlation between inter-observer, intra-observer and inter-modality (MPR-CAG : y=1.0x, r=0.89 , p<0.01 MIP-CAG : y=1.0x+0.1, r=0.88, p<0.01). Conclusion: We found a significant good correlation in the measurements of coronary artery between CTA and CAG. Measurement of the diameters of coronary artery by CTA is reliable and useful.

Flexor Strength

Purpose The classic periacetabular osteotomy (PAO) approach can result in hip flexor weakness in adolescents. The rectus-sparing approach (PAO-RS) preserves the origin of the rectus femoris tendon which may prevent hip flexor weakness and improve functional outcome. Methods This is a prospective analysis of adolescents treated with a PAO or PAO-RS. The PAO group included 24 hips/21 patients (18 female, meanage 16 years (sd 4)); the PAO-RS group included ten hips (eight female, mean age 16 years (sd 1)). Preoperatively, the PAO group had decreased hip flexion strength compared with the PAO-RS group (83 Nm/kg versus 102 Nm/kg). A subset of PAO patients (n = 13 hips/12 patients, nine female, mean age 15 years (sd 3)) were matched for preoperative flexion strength to the PAO-RS group. Radiographic parameters, modified Harris hip score (mHHS), isokinetic hip strength and instrumented motion analysis preoperatively, six months and one-year postoperatively were compared. Results There were no differences in preoperative deformity, postoperative correction or degree of correction between groups. Hip flexor strength decreased significantly at six months in the PAO group compared with the PAO-RS group (-35 Nm/kg versus -7 Nm/kg; p = 0.012), as did hip flexion pull-off power (1.33 W/kg PAO versus 1.76 W/kg PAO-RS; p = 0.010). Hip flexion strength improved from six months to one year in the PAO group, with no significant differences in strength at one year between groups (80 Nm/kg versus 90 Nm/kg). There were no differences between groups in mHHS any time point; both groups improved significantly postoperatively. Conclusion Preserving the rectus femoris may lead to improved short-term hip flexor strength and pull-off power. Further assessment at long-term follow-up is needed to determine if this strength leads to improved functional outcomes. Level of Evidence II
