3-D Printed Casts Offer Patients Customized Solutions for Bone Breaks

Anyone who has ever had to wear a cast can attest to the inconveniences they experience, such as difficulty in showering because the casts are not waterproof, not being able to swim, the heaviness of the cast, and not being able to scratch the inevitable itches. But now, with a new Red Dot Award-winning technology that uses 3-D printing, plaster casts may become a thing of the past, at least when it comes to treating sprains or light fractures. Xkelet casts are 3-D printed using a SLS 3-D printer with the waterproof and hypoallergenic PA2200 plastic material, which is compatible with ISO 10993-1. The casts are lightweight, weighing less than 100 grams. “[The material] is biodegradable, and we can put it in many different colors,” said Tim Dobrinich, COO and co-founder of TriMed, in an interview with MD+DI. TriMed is a major distributor of the casts from Exiom, which owns the exclusive U.S. rights to the products. TriMed also installs and trains medical practitioners who want to provide this service. “What's nice about this product is that it's very breathable, it's very lightweight,” said Dobrinich. “If you have an itch, you can get in there and scratch, you can shower with it, you can swim with it. So, you can become a lot more active.” He cautions that the casts are not suitable as a replacement in every situation, but they are optimal for light fractures or sprains, ...

Purpose of review The present review describes the current role of metabolic imaging techniques such as multiparametric MRI (mpMRI), magnetic resonance spectroscopic imaging (MRSI), hyperpolarized MRSI, and positron emission tomography (PET) in the diagnosis of primary prostate cancer, surveillance of low-grade disease, detection of metastases, and evaluation of biochemical recurrence after therapy. Recent findings The natural history of prostate cancer ranges from indolent disease that is optimally monitored by active surveillance, to highly aggressive disease that can be lethal. Current diagnostic methods remain imp...

Conclusion Potassium iodate blockade is more efficacious compared with potassium perchlorate within the cohort observed. Both visual and quantitative data indicate that potassium iodate given at 30–60 min before 123I-mIBG injection provides comparable blockade effectiveness to lengthier administrations, suggesting that a single dose is well tolerated and practical.

Aim The mylohyoid muscle is often believed to exhibit high physiologic fluoro-deoxy-glucose (FDG) uptake. Aim of this study was to use PET/MR for adequately assessing the normal FDG distribution in floor of the mouth (FOM) muscles and neighboring major salivary glands. Materials and methods Patients scanned with a simultaneous PET/MRI system for initial staging or follow-up of head and neck tumors, with no malignant lesions in salivary glands or in FOM, were included. Volumes-of-interest (VOIs) were positioned separately for bilateral mylohyoid, digastric, genioglossus, and geniohyoid muscles, based on T2-weighted and...

Conclusions L-SURmax showed the most powerful predictive performance than the other PET parameters in predicting occult lymph node metastasis. The combination of three independent risk factors (carcinoembryonic antigen, cytokeratin 19 fragment, and L-SURmax) can effectively predict occult lymph node metastasis in clinical N0 non–small cell lung cancer patients.

Objective The study is to investigate the application of 18F-fluorodeoxyglucose (18F-FDG) PET/computerized tomography (CT) for the evaluation of mantle cell lymphoma (MCL). Methods We retrospectively analyzed 39 patients who were pathologically diagnosed with MCL and underwent 18F-FDG PET/CT before treatment between August 2007 and August 2018. We compared the clinical information and PET/CT imaging characteristics in different groups based on bone marrow invasion, spleen invasion or International Prognostic Index (IPI) score. We also assessed the efficacy of PET/CT evaluation basing on the follow-up PET CT findings o...

Conclusion Semi-quantitative F-18 FDG PET parameters (SUVmax, MTV and T/L) were found to be significantly correlated with Fuhrman grade in patients with RCC and are important markers for differentiation between low- and high-grade tumors. Furthermore, forced diuresis had no incremental value in characterization of primary RCC lesions.

Abstract Pneumocystis jirovecii pneumonia (PJP) occurs in immunocompromised hosts and is classified as PJP with human immunodeficiency virus (HIV) infection (HIV-PJP) and PJP without HIV infection (non-HIV PJP). Non-HIV PJP rapidly progresses to respiratory failure compared with HIV-PJP possibly due to the difference in immune conditions; namely, the prognosis of non-HIV PJP is worse than that of HIV PJP. However, the diagnosis of non-HIV PJP at the early stage is difficult. Herein, we report a case of severe non-HIV PJP successfully managed with veno-venous extracorporeal membrane oxygenation (V-V ECMO). A 54-yea...

Abstract To observe blood vessels at high contrasts, we constructed a first-generation triple-sensitivity X-ray computed tomography (TS-CT) scanner using a cadmium-telluride (CdTe) detector and a triple-amplifying system. X-ray photons are absorbed by the CdTe crystal, and the electric charges produced by photons are converted into voltages using a current-to-voltage (I-V) amplifier, and the I-V output is amplified by a voltage-to-voltage (V-V) amplifier. The V-V output 1 is sent to a dual V-V amplifier through a 5.0-m-length coaxial cable and amplified to two-different outputs of 2 and 3. The three outputs 1-3 ar...
