Comparison of Models for 3D Printing of Solitary Fibrous Tumor Obtained Using Open-Source Segmentation Software
(MDPI, 2022-11-16) Tincopa, Jean Pierre; Salazar-Gamarra, Rodrigo; Lopez-Hinostroza, Madaleine; Moya-Salazar, Belén; Contreras-Pulache, Hans; Moya-Salazar, Belén
“The objective of the present study is to make a comparison between various free and open-source software used for medical image processing, such as 3D Slicer (version 4.11), ITK-Snap (version 3.8), and Invesalius (version 3.1) in its application for the calculation of solitary fibrous tumor volumes. Knowing the size, shape, and volume of mesothelioma is decisive for clinical decisionmaking by health personnel when performing surgery; the currently used standard procedure is manual segmentation through magnetic resonance imaging (MRI). This process tends to take a long time to complete. On the other hand, automatic segmentation software is much faster and more user-friendly, so looking for software that gives us greater accuracy when doing this task is very important. This work obtained magnetic resonance imaging (MRI) of a mesothelioma patient, and the images were segmented in the 3 different programs to evaluate the concordance between the software later.“

Development of 3D-Printed Orthopedic Insoles for Patients with Diabetes and Evaluation with Electronic Pressure Sensors
(MDPI, 2022-10-14) Zuñiga, Juan; Moscoso, Miguel; Padilla-Huamantinco, Pierre G.; Lazo-Porras, Maria; Tenorio-Mucha, Janeth; Padilla-Huamantinco, Wendy; Tincopa, Jean Pierre
“The correct distribution of loads on foot, known as plantar pressures, is a relevant parameter for evaluating the evolution of some diseases. Anomalies can lead to pain and discomfort in other body parts. Diabetes changes foot tissues and compromises biomechanics, resulting in ulcers and, eventually, amputation. Customized insoles allow the redistribution of plantar pressures and are a complementary strategy to diabetes management. Nowadays, scanning and 3D printing technology can generate faster and more accurate customized insoles opening new opportunities for local medical device development. This study reports the development of 3D-printed insoles using two polymers, thermoplastic polyether-polyurethane and thermoplastic polyurethane polyester-based polymer, and the evaluation of plantar pressure distribution in walk trials using a clinical protocol and low-cost electronic system. The two 3D-printed insoles performed as well as a standard insole. No significant difference was found in average peak pressure distribution. The digital manufacturing workflow of customized insoles can be implemented in middle-income countries. Three-dimensionally printed insoles have the potential for diabetes management, and further material evaluations are needed before using them in health facilities.“

“Surgical planning and separation of ischiopagus conjoined twins using 3D printed models and intraoperative neurophysiological monitoring“
(ELSEVIER, 2023-03-08) Rodriguez-De-Velasco, Andres; Apaza, Jose Luis; Rojas, Nora; Martinez, Peggy; Padilla-Huamantinco, Pierre; Zuñiga, Juan Manuel; Jaramillo-Cañas, Winston; Tincopa, Jean Pierre; Quispe-Juli, Cender U.
“The birth of conjoined twins is one of the rarest neonatal conditions worldwide, with an incidence of 1 in 100,000 live births. Twins joined by the pelvis, known as ischiopagus, represent 6–11% of all conjoined twins. This clinical condition increases the degree of complexity in separation surgeries. Each case poses unique anatomical challenges, and clinical outcomes may vary according to the health facility where the infants are born or can access. This case report describes a successful separation surgery of ischiopagus conjoined twins in Peru. 3D printing and neurophysiological monitoring were used for surgical planning and intervention, allowing a fullscale anatomical model and preserving the mobility of the lower limbs of conjoined twins after surgery. This article demonstrates that established procedures and novel technologies can be valuable platforms for preoperative planning and intraoperative guidance to safeguard the central and peripheral nervous systems while increasing survival rates of ischiopagus conjoined twins in middle-income countries such as Peru. “
