Long-standing retroperitoneal schwannoma in a 36-year-old female: A case report.

Introduction: Schwannomas are encapsulated nerve sheath tumors derived from Schwann cells, primarily found in the head, neck, and extremities. Retroperitoneal schwannomas are rare and typically asymptomatic.

Case Presentation: A 36-year-old female presented with a long-standing, asymptomatic right lower abdominal mass.

Hand Injury among Patients Visiting Emergency Department in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: The hand is a complex organ responsible for activities of daily living, making it susceptible to injuries and accidents. Hand injuries can result in significant functional impairment and it occurs in a younger productive age group. Therefore, it is important to understand the prevalence and patterns of hand injuries.

Harvesting the anterolateral thigh flap with non-sizable perforators.

Background: The anterolateral thigh flap (ALT) has proven over time to be one of the best reconstructive workhorses due to its versatility and reliability. Without preoperative imaging, vascular anomalies such as having no sizable perforator are sometimes encountered during dissection. We propose a technique, based on a modified version of the traditional myocutaneous ALT to allow harvest of the flap based on non-sizable perforators.

Plastic Surgical Procedures for Lower Limb Reconstruction at a Tertiary Hospital in Nepal.

Background: This study assessed the lower limb reconstruction outcome so that it will provide a baseline evidence to enable data-driven decision making to improve outcome in the future.

Methods: In this study, hospital records from 1st January to 31st December 2019 were collected retrospectively. Complete data of all patients' records treated for lower limb defects at Kirtipur Hospital were included and incomplete data were excluded.

Pilot Study to Assess Safety and Usability of the Kyron NPWT System.

Unlabelled: There is an evident need for Negative Pressure Wound Therapy (NPWT) systems specifically designed for use in resource-constrained settings to aid in the treatment of open wounds.

Methods: Prospective single-arm interventional pilot study of 14 patients with complex wounds was conducted at Kirtipur Hospital in Kathmandu, Nepal. A novel NPWT device, the Kyron Suction Unit, was used by 4 plastic surgeons.

Review of the First 108 Free Flaps at Public Health Concern Trust-NEPAL Hospitals: Challenges and Opportunities in Developing Countries.

Background: Free tissue transfer is one of the most important and essential techniques in reconstructive surgery. The underlying complexity, steep learning curve, high cost, and fear of failure make it very difficult to establish as a regular service in developing countries such as Nepal.

Methods: A retrospective cohort study design was used to analyze the challenges with and opportunities for reconstructive surgery in Nepal.

Clinical Epidemiology of Acute Burn Injuries at Nepal Cleft and Burn Centre, Kathmandu, Nepal.

Background: Burn injury is a global health problem mainly occurring in developing countries. The Nepal Cleft and Burn Centre at Kirtipur Hospital, Kathmandu, has been providing the acute burn care since 2013 with 7 intensive care unit beds, 30 general beds, and 2 dedicated operating rooms. A similar descriptive study was performed in this center in 2014.

Creation of Nepal's First Skin Bank: Challenges and Outcomes.

Background: In Nepal, burn trauma causes more than 55,000 injuries each year. Burn-related mortality is high in Nepal, in part due to lack of allograft, leading to high infection rates. To address this challenge, our collaboration between Kirtipur Hospital, America Nepal Medical Foundation, Stanford University, and ReSurge International established Nepal's first skin bank.

Arts of electrical impedance tomographic sensing.

This paper reviews governing theorems in electrical impedance sensing for analysing the relationships of boundary voltages obtained from different sensing strategies. It reports that both the boundary voltage values and the associated sensitivity matrix of an alternative sensing strategy can be derived from a set of full independent measurements and sensitivity matrix obtained from other sensing strategy. A new sensing method for regional imaging with limited measurements is reported.

Non-destructive label-free continuous monitoring of in vitro chondrogenesis via electrical conductivity and its anisotropy.

Non-destructive label-free continuous monitoring of in vitro tissue culture is an unmet demand in tissue engineering. Noting that different compositions of cartilage lead to different electrical tissue properties, we propose a new method to measure the electrical conductivity and its anisotropy during in vitro chondrogenesis. We used a conductivity tensor probe with 17 electrodes and a bio-impedance spectroscopy (BIS) device to measure the conductivity values and the anisotropy ratios at the bottom and top surfaces of the tissue samples during the culture period of 6 weeks.
