Prognostic factors for vision outcome after surgical repair of open globe injuries.

Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries. Materials and Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed. Different preoperative variables were correlated with the final visual outcome. Exclusion criteria were patients with less than four months follow up, previous ocular surgery, presence of intraocular foreign body or endophthalmitis at the time of presentation. Using statistical tests, the prognostic factors for vision outcome following surgical repair of open globe injuries were studied. Results: Based on the Spearman's Rho correlation analysis, following factors were found to be significantly associated with the final visual acuity at univariate level: age (P<0.001), preoperative visual acuity (P=0.045), mode of injury (P=0.001), and time lag between the injury and surgery (P=0.003). None of the other clinical factors have statistically significant correlation with final visual acuity. On multivariate analysis using binary logistic regression, only age, mode of injury and the time lag between injury and surgery achieved statistically significant results. Conclusion: In the current study, elapsed time between the injury and surgery, age of the patient, preoperative visual acuity and mode of injury were found to be adversely affecting the final visual outcome. Recognizing these factors prior to surgical intervention or intraoperatively can help the surgeon in evidence-based counseling of the trauma victim and family.

Bone marrow cells for myocardial repair-a new therapeutic concept.

AIM: To assess the safety and feasibility of transfusing autologous bone marrow stem cells (ABMSC) into the culprit coronary artery after an acute anterior wall myocardial infarction (MI) and further to see the ability of ABMSC to promote improvement in Left Ventricular lsqb;LV] function at follow-up. METHODS: In an ongoing phase I clinical trial, twenty-seven patients of uncomplicated acute anterior wall MI treated as per the current practicing guidelines have been included. Among these, seventeen patients received intra-coronary unfractionated ABMSCs from 77ndash;15 days after acute MI (ABMSC group) and ten patients acted as controls. RESULTS: All the procedures carried out were without any complications. After 6 months, cardiac function analysis of ten patients from the ABMSC group by LV angiography and Cardiac Magnetic Resonance Imaging (MRI) demonstrated a significant rise of 12.74% (p = 0.001) and 7.1% (p = 0.001), respectively in the LV ejection fraction [LVEF]. There was an improvement in the LV systolic function wherein LV end systolic volume (LVESV) decreased significanty to 28.75% (p = 0.010) and 16.49% (p = 0.022) by LV angiography and cardiac MRI, respectively. LV end diastolic volume (LVEDV) decreased marginally by LV angiography (p = 0.548) and by cardiac MRI (p = 0.514). Five patients of the control group by LV angiography demonstrated non-significant rise of 1.0% (p = 0.706) in LVEF, 12.79% (p = 0.332) in LVEDV and 22.56% (p = 0.308) in LVESV. By cardiac MRI controls demonstrated significant rise in EF of 3.2% (p = 0.0367rpar; but non-significant fall of only 2.32% (p = 0.812) in LVEDV and 6.47% (p 7equals; 0.508) in LVESV. CONCLUSION: This study shows that intracoronary infusion of ABMSC is safe and feasible after acute MI and shows a favourable trend towards the improvement of LV function and prevention of ventricular remodeling which determines long-term survival.
