A case report on the rare presentation of aneurysmal bone cyst on proximal radius with management

Aneurysmal bone cyst (ABC) is a non-neoplastic vaso-cystic tumor of the second decade. A 16-year-old male patient presented to the outpatient department with gradual dull aching pain and progressive increasing swelling, which was localized to right lateral elbow and upper part of the forearm. There was no restriction in the range of motion. After getting an x-ray, a lytic lesion is found at the proximal radius. MRI and cytology, are both investigations done to confirm the diagnosis. Two injections of 10 ml polidocanol (3%) were administered percutaneously two months apart under the guidance of an image intensifier. After one year X-ray showed marked sclerotic, however, the tumor size remained almost the same. Although ABC is a non-aggressive benign lesion. ABC responds to treatment very well. recurrence is also common. Proximal radius is a less common site for ABC and the case report suggests that it is curable. We found no recurrence. Treatment with polidocanol is less expensive, less morbid, has a good functional outcome, early discharge from the hospital, and highly effective.

Unicrypt: A Constructive Approach Towards Rainbow Table Vulnerability

This project shows how we can eliminate the threat of password cracking by rainbow table. In this project we had made an encipher which encrypts our message or password in such a way that it becomes impossible to make a complete rainbow table for it which thus protects us from rainbow table attack used by professional hackers to crack the password. The encipher encrypts our message such that a different hash value is created every time, even if you encrypt the same message more than one time</jats:p

Navigating the Future: challenges and opportunities in intelligent RPA implementation

The Chapter investigates the transition from RPA to IPA and its revolutionary impact on businesses in the digital age. The study carefully analyzes the key challenges and opportunities that have accompanied the adoption of IPA in organizational workflows. The report exploits a detailed literature review to establish major trends and business issues when using IPA systems. It addresses the organizational, technological, and human-centric challenges that relate to leadership matters, resistance to change management, and gaps in skills for handling automation technologies. The findings suggest that although IPA can greatly improve operational efficiency through automated routine tasks, it poses challenges in role redefinition at work, in higher-order talent enhancement for employees, and in countering opposition to automation. However, for IPA adopting AI technologies such as machine learning and natural language processing will provide new ways to manage complex activities and streamline data-driven decision-making

Flipped Reposition Laminoplasty for Excision of Intradural Extramedullary Tumors in the Thoracolumbar Spine: A Case Series of 14 Patients

Study Design: A retrospective study was done to assess the outcome of the new technique of flipped reposition laminoplasty for excision of intradural extramedullary (IDEM) spinal tumors of the thoracolumbar region.Purpose: To describe flipped reposition laminoplasty technique and evaluate its outcomes. Overview of Literature: Laminectomy has been the conventional approach for the surgical excision of IDEM spinal tumors, but it has potential postoperative complications. Laminoplasty maintains the posterior arch of the spine and avoids complications seen in Laminectomy, such as instability, epidural scarring, and kyphotic deformity.Methods: Fourteen patients (nine females and five males) diagnosed with IDEM tumors of the thoracolumbar region operated between 2016 and 2018 were included in this study. Pathologically, five cases were schwannomas; four cases were meningiomas; two cases were ependymomas; and one case each was lymphoma, neurofibroma, and teratoma. All patients had their neurological deficits documented using the American Spinal Injury Association (ASIA) impairment scale. After completion of all preanesthetic formalities, the patients were operated upon by a single surgeon using the flipped reposition laminoplasty technique. Follow-up was done at 1, 3, 6, and 12 months post operation and yearly thereafter.Results: The mean age of the patients was 35.28 years (14–65 years), and the mean follow-up duration was 17 months (6–26 months). Two patients were assessed with ASIA grade A neurology, one patient improved to ASIA grade B, whereas the other did not improve. Two patients improved from ASIA grade B to ASIA grade D, and seven patients with ASIA grades C and D improved to ASIA grade E. Fusion at the osteotomy site was seen in 92.85% (13 out of 14) cases on one side within 6 months post operation. Fusion was seen in all the cases within 1 year post operation.Conclusions: Flipped reposition laminoplasty is an excellent technique providing adequate exposure and additional stability postoperatively.</jats:p
