Multiple unilateral variations in medial and lateral cords of brachial plexus and their branches
Shivi Goel,Shaifaly Madan Rustagi,Ashwani Kumar,Vandana Mehta,Rajesh Kumar Suri 대한해부학회 2014 Anatomy & Cell Biology Vol.47 No.1
During routine dissection of the upper extremity of an adult male cadaver, multiple variations in branches of medial and lateral cords of brachial plexus were encountered. Three unique findings were observed. First, intercordal neural communications between the lateral and medial cords were observed. Second, two lateral pectoral nerves and one medial pectoral nerve were seen to arise from the lateral and medial cord respectively. The musculocutaneous nerve did not pierce the coracobrachialis. Finally, the ulnar nerve arose by two roots from the medial cord. Knowledge of such variations is of interest to anatomists, radiologists, neurologists, anesthesiologists, and surgeons. The aim of our study is to provide additional information about abnormal brachial plexus and its clinical implications.

Effect of Rosiglitazone in Sodium Arsenite-induced Experimental Vascular Endothelial Dysfunction
Tajpreet Kaur,Rajesh Kumar Goel,Pitchai Balakumar 대한약학회 2010 Archives of Pharmacal Research Vol.33 No.4
The present study has been designed to investigate the effect of rosiglitazone, a peroxisome proliferator activated receptor γ agonist in sodium arsenite-induced vascular endothelial dysfunction (VED) in rats. The rats were administered sodium arsenite (1.5 mg/kg/day, i.p., 2 weeks) to induce VED. The development of VED was assessed by employing isolated aortic ring preparation and estimating serum nitrite/nitrate concentration. Further,the integrity of the aortic endothelium was assessed histologically using haematoxylin-eosin staining. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances, aortic reactive oxygen species and reduced form of glutathione. The administration of sodium arsenite produced VED by impairing acetylcholine-induced endothelium dependent relaxation, diminishing the integrity of vascular endothelium and decreasing the serum nitrite/nitrate concentration. In addition, sodium arsenite was noted to produce oxidative stress as it increased serum thiobarbituric acid reactive substances and aortic reactive oxygen species and consequently decreased glutathione. Treatment with rosiglitazone (3 mg/kg/day, p.o., 2 weeks and 5 mg/kg/day, p.o., 2 weeks) significantly prevented sodium arsenite-induced VED by enhancing acetylcholine-induced endothelium dependent relaxation, improving the integrity of vascular endothelium, increasing the nitrite/nitrate concentration and decreasing the oxidative stress. However, the vascular protective effect of rosiglitazone was markedly abolished by co-administration of nitric oxide synthase inhibitor, N-Omega-Nitro-L-Arginine Methyl Ester (L-NAME) (25 mg/kg/day, i.p., 2 weeks). Thus, it may be concluded that rosiglitazone reduces oxidative stress, activates eNOS and enhances the generation of nitric oxide to prevent sodium arsenite-induced VED in rats.

Purpose: The purpose of this study is to describe a method of inserting cement in the femoral head before fixation with dynamic hip screw to prevent screw cut out due to osteoporosis and to evaluate its clinical outcome in these patients. Materials and Methods: In this prospective study, 30 patients aged 60 years and older with intertrochanteric fracture were included. Bone mineral density was measured. After reaming of the femoral head and neck with a triple reamer and polymethyl methacrylate, bone cement was introduced into the femoral head using a customized nozzle and a barrel fitted on a cement gun. A Richard screw was inserted and the plate was fixed over the femoral shaft. Patients were mobilized and clinical outcomes were rated using the Salvati and Wilson’s scoring system. Results: More patients included in this study were between 66 and 70 years old than any other age group. The most common fracture according to the Orthopaedic Trauma Association classification was type 31A2.2 (46.7%). The T-score was found to be –2.506±0.22 (mean±standard deviation); all patients were within the range of –2.0 to –2.8. The duration of radiological union was 13.67±1.77 weeks. Salvati and Wilson’s scoring at 12 months of follow up was 30.96±4.97. The majority of patients were able to perform their normal routine activities; none experienced implant failure or screw cut out. Conclusion: Bone cement augmentation may effectively prevent osteoporosis-related hardware complications like screw cut out in elderly patients experiencing intertrochanteric fractures.

Primary hepatic tuberculosis is a rare entity and can closely mimic malignancy with respect to clinical presentation and imaging features. We identified five patients at a high volume tertiary care cancer center, whose clinical features and imaging closely mimicked primary liver malignancy or metastases but final histopathology was suggestive of hepatic tuberculosis. Three patients underwent a surgical resection whereas two were diagnosed on a biopsy. Anti-tuberculosis therapy was started for all the patients which was well tolerated. All patients are doing well at the time of the last follow up. This case series stresses the importance of having a high index of suspicion and preoperative biopsy in cases where imaging features are equivocal.

Extracapsular excision of hepatic hemangioma
Amol Kanetkar,Shubham Garg,Shraddha Patkar,Rajesh S Shinde,Mahesh Goel 한국간담췌외과학회 2018 Annals of hepato-biliary-pancreatic surgery Vol.22 No.2
Backgrounds/Aims: Hepatic hemangioma is a common non-epithelial neoplasm of the liver. Presence of symptoms and uncertainty in diagnosis are the most common indications for surgery. Methods: Eighteen patients with hepatic hemangioma, operated on from January 2011 to December 2016 at the Hepato-pancreato-biliary surgical unit of Tata Memorial Hospital, were retrospectively analyzed. Results: Main indications for operation were presence of symptoms, the most common being pain and diagnostic uncertainty. The median size of hemangioma was 9.9 cm (range 3.2 to 24 ㎝). All patients underwent extra-capsular excision of hemangioma. The median operating time was 180 minutes (range 75 to 460 minutes) and median blood loss was 950 ml (range 100 to 3,500 ml). Median post-operative stay was 5.5 days (range 3 to 10 days). One (5.6%) patient required re-exploration for post-operative hemorrhage, Clavien Dindo (CD) grade IIIb, and one (5.6%) had postoperative purulent intra-abdominal collection requiring percutaneous cutaneous drainage CD grade IIIa. There was no postoperative mortality. Postoperative day 3 liver function tests were within normal limits. Size of the tumor did not correlate significantly with postoperative complications (p=0.135). Conclusions: Surgical treatment of hemangioma should be guided by presence of symptoms or by the presence of diagnostic uncertainty, not by size alone. The size had no correlation with perioperative complications. The technique of extra-capsular excision is safe and technically feasible in most of the hemangiomas. This technique preserves maximum liver parenchyma, resulting in early postoperative recovery with minimal morbidity.
