Objective: To evaluate the in-vivo antioxidant potential of ethanolic extract of Mentha Pulegium against CCl4 induced toxicity in rats. Methods: Animals were treated with plant extract for 7 days and then toxicity was induced with a single CCl4 intraperitoneal injection. Pre-treatment with 600 mg/kg (p.o.) of ethanolic extract of Mentha Pulegium improved the glutathione, SOD, catalase, and peroxidase levels significantly as compared to control group. Results: The present studies revealed that Mentha Pulegium has significant in-vivo antioxidant activity and can be used to protect tissue from oxidative stress. The result showed that the activities of glutathione, SOD, catalase and peroxidase in group treated with CCl4 declined significantly than that of normal group. Conclusion: Ethanolic extract of Mentha Pulegium in the dose of 600 mg/kg, p.o., has improved the glutathione, SOD, catalase, and peroxidase levels significantly, which were comparable with Liv 52. Based on this study we conclude that Ethanolic extract of MenthaPulegium possesses in vivo antioxidant activity and can be employed in protecting tissue from oxidative stress.

Objective: Anti-fertility activity of ethanolic extract of Jatropha gossypifolia leaf in female albino mice. Methods: Jatropha gossypifolia leaf extract, when administered orally, altered the estrous cycle pattern in female mice, prolong the length of estrous cycle with significant increase in the duration of diestrus stage and reduced significantly the number of litters in albino mice. Treatment of mice with extract of 250 and 450 mg/kg body weight/day for 21 days caused a prolonged estrous cycle with significant increase in the duration of diestrus phase and elongation of estrus stage in treatment with higher dose (450 mg/kg body weight/day). Results: The analysis of the principal hormones involved in estrous cycle regulation showed that the plant extracts altered gonadrotrophin release (LH, FSH and prolactinn) and estradiol secretion. Conclusions:The results indicated the anti-fertility effect of Jatropha gossypifolia leaf extract in female albino mice.

STUDY DESIGN: Prospective clinical study. PURPOSE: The purpose of this study was to evaluate the effect of interlaminar fusion and short segment pedicle screw fixation on thoracolumbar vertebral injuries for preventing pain and post-traumatic kyphosis. OVERVIEW OF LITERATURE: The treatment of thoracolumbar injuries continues to be one of the most controversial areas in spine care. The main aim of surgical treatment is to decompress the spinal cord or nerve roots, realign the spine, and correct or prevent post-traumatic kyphosis. We evaluated the outcome of interlaminar fusion along with posterior decompression and short segment pedicle screw fixation in patients with thoracolumbar fractures with neurological deficit. METHODS: Twenty-two patients with traumatic thoracolumbar vertebral injuries and neurological deficit underwent short segment pedicle screw fixation above and below the fractured vertebrae, posterior decompression, and interlaminar fusion using a bone graft. RESULTS: All patients were followed up for 12 months postoperatively. The average operative time and blood loss was 142 minutes and 214 mL, respectively. Of the 22 patients, 14 recovered completely. Of the nine patients with American Spinal Injury Association (ASIA) grade A disease, two improved by 1 grade, whereas one each improved by grades 2, 3, and 4, and four did not recover. Radiologically, vertebral kyphosis angle improved from 20.91 preoperatively to 15.73 postoperatively, sagittal index improved from 24.77 to 18.73, the sagittal plane kyphosis angle improved from 17.45 to 11.41, regional angle kyphosis improved from 14.73 to 10.14, the superior inferior end plate angle from 16.14 to 13.00, and mean anterior body compression improved from 36.26 to 27.64 postoperatively. No implant failed and no patient had neurological deterioration. CONCLUSIONS: Short segment pedicle screw fixation with posterior decompression and interlaminar fusion provided considerable reduction in kyphosis, restored the vertebral height of patients with thoracolumbar vertebral injuries and neurological deficit, and prevented development of delayed kyphotic deformity.

Caudal epidural steroid injection is a very common intervention in treatment of low back pain and sciatica symptoms. Although extensively used, it is not devoid of complications. A few reports of chemical and infective arachnoiditis exist following lumbar epidural anaesthesia, but none following a caudal epidural steroid injection.We report a case of arachnoiditis following caudal epidural steroid injections for lumbar radiculopathy. The patient presented with contralateral sciatica, worsening low back pain and urinary retention few days following the injection, followed by worsening motor functions in L4/L5/S1 myotomes with resultant dense foot drop. Gadolinium-enhanced magnetic resonance imaging suggested infective arachnoiditis with diffuse enhancement and clumping of the nerve roots within the lumbar and sacral thecal sac. As the number of injections in the management of back pain and lumbo-sacral radicular pain is increasing annually, it is imperative to have a thorough understanding of this potentially dangerous complication and educate the patients appropriately.

Bone provides mechanical support, and flexibility to the body as a structural frame work along with mineral storage, homeostasis, and blood pH regulation. The repair and/or replacement of injured or defective bone with healthy bone or bone substitute is a critical problem in orthopedic treatment. Recent advances in tissue engineering have shown promising results in developing bone material capable of substituting the conventional autogenic or allogenic bone transplants. In the present review, we have discussed natural and synthetic scaffold materials such as metal and metal alloys, ceramics, polymers, etc. which are widely being used along with their cellular counterparts such as stem cells in bone tissue engineering with their pros and cons.

High-energy tibial plateau fracture poses a significant challenge and difficulty for orthopaedic surgeons. Fracture of tibial plateau involves major weight bearing joint and may alter knee kinematics. Anatomic reconstruction of the proximal tibial articular surfaces, restoration of the limb axis (limb alignment) and stable fixation permitting early joint motion are the goals of the treatment. In cases of complex bicondylar tibial plateau fractures, isolated lateral plating is frequently associated with varus malalignment and better results have been obtained with bilateral plating through dual incisions. However sometimes a complex type of bicondylar tibial plateau fractures is encountered in which medial plateau has a biplaner fracture in posterior coronal plane as well as sagittal plane. In such fractures it is imperative to fix the medial plateau with buttressing in both planes. One such fracture pattern of the proximal tibia managed by triple plating through dual posteromedial and anterolateral incisions is discussed in this case report with emphasis on mechanisms of this type of injury, surgical approach and management.

Carcinomas arising from an exstrophic urinary bladder are rare entities, and only seven such cases have been reported in the literature. We present the eighth case of advanced squamous cell carcinoma arising from an exstrophic bladder, with a pertinent review of the literature. The mean age of the patients was 54.9 years, with a male to female ratio of 3:1. The average duration of symptoms was 18.6 months. The appearance of a new growth was the most common symptom. Three patients had stage I disease, one patient each had stage II and III disease, two patients had stage IV disease, and the disease stage was not known in one patient. Five out of these eight patients underwent surgery. Four patients in the treatment group remained disease-free, with a mean survival period of 30 months. In conclusion, regular surveillance with cystoscopy is advised in all cases that had primary closure of the exstrophic bladder.

BACKGROUND/AIMS: Although the diagnostic accuracy of endoscopic ultrasound with fine needle aspiration (EUS-FNA) in pancreas adenocarcinoma is high, endoscopic ultrasound with fine needle biopsy (EUS-FNB) is often required in other lesions; in these cases, it may be possible to forgo initial EUS-FNA and rapid on-site cytology evaluation (ROSE). The aim of this study was to compare the diagnostic accuracy of EUS-FNB alone (EUS-FNB group) with a conventional sampling algorithm of EUS-FNA with ROSE followed by EUS-FNB (EUS-FNA/B group) in nonpancreas adenocarcinoma lesions. METHODS: Retrospective cohort study of subjects who underwent EUS sampling of nonpancreatic adenocarcinoma lesions between February 2011 and May 2013. RESULTS: Over the study period, there were 43 lesions biopsied in 41 unique patients in the EUS-FNB group and 53 patients in the EUS-FNA/B group. Overall diagnostic accuracy was similar between the EUS-FNB and EUS-FNA/B groups (83.7% vs. 84.9%; p=1.0). In the subgroup of subepithelial mass lesions, diagnostic accuracy remained similar in the EUS-FNB and EUS-FNA/B groups (81.0% and 70.6%; p=0.7). EUS-FNB procedures were significantly shorter than those in the EUS-FNA/B group (58.4 minutes vs. 73.5 minutes; p<0.0001). CONCLUSIONS: EUS-FNB without on-site cytology provides a high diagnostic accuracy in nonpancreas adenocarcinoma lesions. There appears to be no additive benefit with initial EUS-FNA but this requires further study in a prospective study.

Segmentation of fundamental heart sounds–S1 and S2 is important for automated monitoring of cardiac activity including diagnosis of the heart diseases. This pa-per proposes a novel hybrid method for S1 and S2 heart sound segmentation using group sparsity denoising and variation mode decomposition (VMD) technique. In the proposed method, the measured phonocardiogram (PCG) signals are denoised using group sparsity algorithm by exploiting the group sparse (GS) property of PCG signals. The denoised GS-PCG signals are then decomposed into subsequent modes with specific spectral characteristics using VMD algorithm. The appropriate mode for further processing is selected based on mode central frequencies and mode energy. It is then followed by the extraction of Hilbert envelope (HEnv) and a thresholding on the selected mode to segment S1 and S2 heart sounds. The performance advantage of the proposed method is verified using PCG signals from benchmark databases namely eGeneralMedical, Littmann, Washington, and Michigan. The proposed hybrid algorithm has achieved a sensitivity of 100%, positive predictivity of 98%, accuracy of 98% and detection error rate of 1.5%. The promising results obtained suggest that proposed approach can be considered for automated heart sound segmentation.
