Background: Rubber bullets and pellet guns are considered non-lethal low-velocity weapons. They are used to disperse a mob during street protests. The present study was undertaken to analyze the pattern, presentation and management of vascular injuries caused by these weapons., Patients and Methods: This was a prospective study of patients with features of vascular injuries due to pellets and rubber bullets from June 2010 to November 2010. All patients with features of vascular injuries due to these non-lethal weapons were included in the study. Vascular injuries caused by other causes were excluded from the study., Results: A total of 35 patients who presented with features of vascular injury during this period were studied. All of them were males. The mean age was 22 years. Fifteen patients were revascularized primarily, 19 patients needed reverse saphenous vein graft and, in one, patient lateral repair was done. There were two mortalities in our series. Wound infection was the most common complication. The amputation rate was around 6%., Conclusion: Pellet and rubber bullets can cause serious life-threatening injuries. Vascular injury caused by these weapons need no different approach than other vascular injuries. Early revascularization and prompt resuscitation prevents the loss of limb or life.

Background: Missile cardiovascular injuries have taken an epidemic proportion in Kashmir valley since the eruption of militancy in 1990. Present study was undertaken to analyse the pattern, presentation and management of missile cardiovascular injuries., Patients and Methods: Three hundred and eighty-six patients with missile cardiovascular injuries since Jan 1996 to Oct 2008 were studied retrospectively. All patients of cardiovascular injuries due to causes other than missiles were excluded from the study., Results: All patients of missile cardiac injuries were treated by primary cardiorrhaphy. Right ventricle was the most commonly affected chamber. Left anterior thoracotomy was most common approach used. Most of the patients of missile vascular group were treated by reverse saphenous vein graft or end-to-end anastomosis. Most common complication was wound infection (20.83%) followed by graft occlusion (1.94%) in missile vascular group. Amputation rate was 4.66%. Amputation rate was higher in patients with delay of >6 hours and associated fractures., Conclusion: Missile cardiac injuries should be operated early without wasting time for investigations. Clinical status at arrival, time interval till management, nature of injury and associated injuries, tell upon the mortality. Missile vascular injury needs prompt resuscitation and revascularization at the earliest. Time interval till revascularization and associated fractures has a bearing on mortality and morbidity.

Background: Bear mauling is rarely reported in medical literature due to its rare occurrence. Present study was undertaken to describe the pattern and management of bear maul vascular injuries in Kashmir., Patients and Methods: Study of patients with bear maul vascular injury from 1(st) Jan 2004 to 31(st) Dec. 2008. Fifteen patients with bear maul vascular injury were studied. All patients of bear maul without vascular injury were excluded from the study., Results: Most of the patients were treated by reverse saphenous vein graft or end to end anastomosis. Most common complication was wound infection (20%) followed by graft occlusion (13.33%). There was no operative death., Conclusion: Bear attacks are very common in Kashmir. Vascular injury due to bear maul needs prompt resuscitation and revascularization. Results are very good provided timely intervention for revascularization is done.

Background/aim: Precise evaluation of lymph node status is one of the most important factors in determining clinical outcome in treating gastro-intestinal (GI) cancer. Sentinel lymph node (SLN) mapping clearly has become highly feasible and accurate in staging GI cancer. This study aims to investigate the feasibility and accuracy of detection of SLN using methylene blue dye in patients with carcinoma of the esophagus and assess its potential role in determining the rational extent of lymphadenectomy in esophageal cancer surgery., Materials and Methods: Thirty-two patients of esophageal cancer diagnosed on endoscopic biopsy were enrolled in this prospective study. After laparotomy, patent methylene blue was injected into the subserosal layer adjacent to the tumor. SLNs were defined as blue stained nodes within a period of 5 min. Standard radical esophagogastrectomy with lymphadenectomy was performed in all the patients. All the resected nodes were examined postoperatively by routine hematoxylin and eosin stain for elucidating the presence of metastasis, and the negative SLNs were examined further with cytokeratin immunohistochemical staining., Results: SLNs were detected in 26 (81.25%) patients out of 32 patients who were studied. The number of SLNs ranged from 1 to 4 with a mean value of 1.7 per case. The SLNs of esophageal cancer were only found in N1 area in 21 (80.77%) cases, and in N2 or N3 area in only 19.33%. The overall accuracy of the procedure was 75% in predicting nodal metastasis. SLN had a sensitivity of 85.71% in mid esophageal tumors and 93.33% in lower esophageal tumors. The SLN biopsy had sensitivity of 87.5% in the case of squamous cell carcinoma and 92.86% in the cases of adenocarcinoma of the esophagus. The accuracy of the procedure for squamous cell carcinoma and adenocarcinoma was 60% and 76.47%, respectively., Conclusion: SLN mapping is an accurate diagnostic procedure for detecting lymph node metastasis in patients with esophageal cancer and may indicate rational extent of lymphadenectomy in these patients. SLN mapping provides "right nodes" to the pathologists for detailed analysis and appropriate staging, thereby helping in individualizing the multi-modal treatment for esophageal cancer.
