Peroneus Longus Tendon Autograft for Anterior Cruciate Ligament Reconstruction: A Safe and Effective Alternative in Nonathletic Patients.

INTRODUCTION: Anterior cruciate ligament (ACL) is a common injury which has been conventionally managed by various graft reconstruction using bone patellar tendon bone, or quadruple hamstring autograft, to name a few. However, all these grafts are associated with many complications. Lately, peroneus longus tendon (PLT) autograft has shown promising results in this field, although there is still a dearth of data on its use. We, therefore, aimed at carrying out a study to evaluate the functional outcome and knee stability results of ACL reconstruction using PLT graft. PATIENTS AND METHODS: Patients with a completely torn ACL were included in the study. The PLT was harvested, and graft length, thickness, and harvesting time were noted intraoperatively. Knee stability and functional scores were evaluated clinically and using Lachman test (primarily) and KT-2000 arthrometer and subjectively with International Knee Documentation Committee (IKDC) score at 6, 12, and 24 months (secondary outcome) postoperatively. Ankle scores were also recorded by making use of American Orthopedic Foot and Ankle Score (AOFAS)-Hindfoot Scale. RESULTS: Forty-eight patients met the inclusion criteria. The graft harvest time was 7.4 min (5-9 min). The mean thickness of the graft on doubling was 7.9 mm (7-9 mm). Ninety-six percent of the patients were satisfied with their results of the knee surgery, and 95% of the patients had no complaints of ankle joint. The mean IKDC score postoperatively was 78.16 ± 6.23, and the mean AOFAS score was 98.4 ± 4.1. None of the patients had any neurovascular deficit. CONCLUSION: ACL reconstruction using PLT graft yields a good functional score (IKDC, KT-2000 arthrometer) even at 2-year follow-up. It is a safe and effective autograft option for ACL reconstruction.

Outcome of 6 months MBMDT in MB patients in Bangladesh- preliminary results.

Introduction: Duration of leprosy treatment remains long and difficult to complete in resource poor areas. Studies suggest that shortening duration of therapy for MB patients to 6 months may be possible. Methods: New MB patients in 2005 in two NGO projects in Bangladesh were treated with 6 months WHO MB MDT and the rate of relapse and fall in BI on slit skin smear during follow up to date were compared with a control group treated for 12 months the previous year. Results: 1612 patients were enrolled in the trial, and the average duration of follow up was over 7 years after diagnosis. During 11,425 PYAR of follow-up, no relapses were detected, by bacteriological or clinical criteria, in the 918 patients in the 6 months MB MDT group, nor in the 694 patients in the control group. Rate of decline of BI in those who were smear positive was not significantly different between groups. Conclusion: The data does not suggest that shortening duration of treatment from 2 months to 6 months MDT for MB leprosy patients leads to increased rates of relapse.

Activities of cyclooxygenases, and levels of prostaglandins E2 and F2alpha, in fetopathy associated with experimental diabetic gestation.

AIM: The present study investigated the cyclooxygenase (COX) pathway to elucidate any changes that may be involved in the mechanism(s) underlying diabetic fetopathy. METHODS: Diabetes was induced in female rats (n=12) by two successive daily injections of 55 mg/kg streptozotocin, while control animals (n=10) were injected with a buffer solution; hyperglycaemia was confirmed by blood glucose levels greater than 11 mmol/L. The study female rats were made pregnant and, on day 15 of gestation, the rats were sacrificed, and the fetuses, placentas and membranes dissected out of the uterine horns. Following morphological examination, the fetuses, placentas and membranes were homogenized, and used to measure COX activities and prostaglandin (PG) E(2) and PGF(2alpha) levels. RESULTS: Fetuses from diabetic mothers exhibited significantly (P<0.05) shorter crown-to-rump lengths, lower body weights and heavier placental weights. The activity of COX-1 in the fetuses, placentas and membranes from diabetic mothers represented a small percentage of total COX activity compared with that of COX-2. The presence of a COX-1 inhibitor in the control and diabetic rats was investigated and found to be negative. The activity of COX-2 in malformed fetuses from diabetic mothers was significantly lower (P<0.05) compared with non-malformed fetuses from control and diabetic mothers. The mean level of PGE(2) in fetuses from diabetic mothers was significantly (P<0.05) lower than that in controls. In contrast, the biggest increases in PGF(2alpha) were observed in the malformed diabetic fetuses, placentas and membranes. CONCLUSION: The increased production of PGF(2alpha) probably proceeds, at least in part, independently of the COX pathway and via the isoprostane route. However, it is unclear whether the relatively high levels of PGF(2alpha) are causally related to, or simply coincidental with, fetal malformation.

The levels of vascular endothelial growth factor-A and placental growth factor-2 in embryopathy associated with experimental diabetic gestation.

The objective of this study was to investigate the role of vascular endothelial growth factor-A (VEGF-A) and placental growth factor-2 (PlGF-2) in fetal malformations associated with maternal diabetes. Diabetes was induced in female rats. Diabetic and control female rats were made pregnant. On Day 15 of gestation, rats were sacrificed and embryos and their placentas and membranes were dissected out of the uterine horns. Following morphological examination, embryos and their placentas and membranes were homogenized and used for assayed of VEGF-A and PlGF-2 levels. Embryos of diabetic mothers, exhibited significantly (P < 0.05) shorter crown-to-rump lengths, smaller weights, and heavier placental weights. Experimentally induced maternal diabetes was accompanied by decreased VEGF-A in embryos and associated structures. The levels of PlGF-2 in non-malformed embryos of diabetic gestation and their placentas were significantly (P < 0.05) lower than the average of controls. These results might indicate defective vascularization with a consequent morphological or anatomical anomalies or more subtle biochemical or metabolic changes. In diabetic mothers, a statistically significant (P < 0.05) decrease was noted in the level of VEGF-A in plasma of diabetic rats with a small non-significant decrease in PlGF-2. Like many other diabetic complications, diabetes-induced embryopathies might have vascular origin and correcting the disturbances in these angiogenic factors might help decrease the incidence of malformation in diabetic gestation.
