1.A Prospective Randomized Controlled Study of Stratafix versus Standard-of-Care for Deep Tissue Closure in Orthopedic Surgery
Clinics in Orthopedic Surgery 2024;16(5):820-826
Background:
Orthopedic deep surgical incisions require the approximation of 1 or multiple tissue layers. This prospective randomized controlled study aimed to assess the usefulness and effectiveness of a barbed suture technique (Stratafix symmetric PDS plus) versus the conventional interrupted knotted suture technique for deep tissue closure in orthopedic surgery by comparing deep fascia suture time, relative cost, and wound-related complications.
Methods:
A total of 254 patients with deep surgical incisions who underwent orthopedic surgery between October 1, 2020, and June 30, 2021, were recruited. Their general characteristics (age, sex, weight, height, body mass index, American Society of Anesthesiologists physical status score, total operation time, and length of deep incision) and factors related to deep incision wounds (suture type and number, wound closure time, and operation site outcomes) were collected.
Results:
The general characteristics did not differ between the Stratafix and conventional groups. There were no between-group differences observed in total operation time or total anesthesia time. The wound suture times differed significantly. In the conventional group, the suture time per unit length was lower in the group with the length of deep incision under 20 cm but did not differ significantly for each wound size. In the Stratafix group, the suture time per unit length was lower in the group under 15 cm, with the shortest time observed for 10–14.9 cm, followed by 5.0–9.9 cm and the group under 5 cm. The conventional group developed 4 cases of superficial wound infection or surgical wound necrosis. One case of protruded suture tap occurred in the Stratafix group.
Conclusions
The average suture time per unit length increased for lengths under 5 cm as barbed sutures required more time from the start of the first suture to finish of the last suture. There was no significant benefit for very short suture length. One barbed suture material allows a suture of approximately 10–12 cm; sutures beyond that require more time because the surgeon has to start again. The Stratafix group used less suture material than the conventional group.

Microplastics are environmental pollutants that prevail in the oceans, remote islands, and polar regions. Exposure to microplastics presents a major emerging threat to the ecosystems due to their potential adverse effects. Herein, we reviewed the literature to provide an up-to-date synopsis of the current understanding of the sources, compositions, and adverse effects of microplastics in humans and the environment. Most studies on microplastics have focused on developing standardized methods for monitoring the occurrence, distribution, and movement of microplastics in the environment, as well as developing microplastic substitutes; however, although humans are exposed to microplastics via various routes, research on the adverse effects of microplastics in humans remains limited. Little is known about the impact of microplastics on human health and the toxic effects that may vary depending on the type, size, shape, and concentration of microplastics. Therefore, more research is needed to understand the cellular and molecular mechanisms of microplastic toxicity and related pathologies.

Purpose:
This study examined the results of internal fixation using an intramedullary nail in the treatment of distal metaphyseal fractures involving the articular surface.
Materials and Methods:
From November 2009 to November 2018, distal tibia fractures involving the articular surface were treated with intramedullary nailing only for fractures corresponding to AO type 43 B and 43 C1, twenty-four cases were studied retrospectively. The tibial alignment was measured preoperatively and postoperatively, and the bone union time and nonunion were assessed. In addition, the clinical evaluation of ankle joint function was assessed using the Olerud and Molander ankle score (OMAS).
Results:
Complete bone union was obtained in all cases, and the mean union time was 17.7±1.87 weeks (range, 15-20 weeks). The average preoperative coronal alignment was 6.4°±1.0° (range, 5.2°-8.4°), and sagittal alignment was 2.7°±0.6° (range, 1.9°-3.8°). The average postoperative coronal alignment was 2.5°±0.13° (range, 2.2°-2.6°) and sagittal alignment was 0.4°±0.25° (range, 0.09°-0.95°). There was no nonunion. The OMAS had an average of 85±7.9 points (range, 70-95 points).
Conclusion
In the treatment of distal metaphyseal fractures involving the articular surface, internal fixation using an intramedullary nail reduces complications and achieves satisfactory reduction and union.This method is considered an excellent treatment to obtain good clinical results.

Purpose:
Intramedullary nailing is used widely for treating tibial diaphysis fractures because of its relatively rigid internal fixation, which allows weight bearing, resulting in rapid bone healing and functional recovery. This study evaluated the results of exchange nailing in treating aseptic nonunion of tibial shaft fractures.
Materials and Methods:
From November 2015 to December 2021, a retrospective study was conducted on patients who had undergone intramedullary nailing for tibial diaphysis fractures. Among them, this study focused on patients diagnosed with nonunion and who underwent exchange nailing. Twenty patients with a minimum follow-up period of at least 12 months were included in the study.
Results:
The mean ages of patients were 60 years (range, 30-79 years). Of the 20 cases in which exchange nailing was performed, bone union was achieved in 18 cases (90.0%), and the mean period was 23 weeks (range, 14-46 weeks). Among the 18 cases of bone union, one case exhibited delayed union and achieved union without additional treatment after 46 weeks, while two cases of nonunion failed to achieve union and were lost to follow-up until the final assessment.
Conclusion
Reamed exchange nailing performed on aseptic nonunion after intramedullary nailing for tibial diaphysis fractures had satisfactory clinical outcomes.

Tumoral calcinosis (TC) is a condition resulting from extensive calcium phosphate precipitation, primarily in the periarticular tissues around major joints. Calciphylaxis is a fatal ischemic vasculopathy mainly affecting dermal blood vessels and subcutaneous fat. This syndrome is rare and predominantly occurs in patients with end-stage renal disease. Here, we report on a rare case involving a patient with TC complicated with calciphylaxis. Our patient was a 31-year-old man undergoing hemodialysis who presented with masses on both shoulders and necrotic cutaneous ulcers, which were associated with secondary hyperparathyroidism, on his lower legs. He underwent subtotal parathyroidectomy, and sodium thiosulfate (STS) was administered for 27 weeks. Twenty months after beginning the STS treatment course, he experienced dramatic relief of his TC and calciphylaxis.

BACKGROUND: Self-monitoring of blood glucose is an important component of therapy for diabetes mellitus. The aim of this study was to evaluate the analytic performance evaluation of blood monitoring system G400 according to ISO 15197:2013. METHODS: We evaluated the G400 according to the ISO 15197:2013 guideline, we measured precision, accuracy, interference of hematocrit and interfering substances, user performance. RESULTS: Repeatability and intermediate precision of G400 showed standard deviation 2.7–3.8 mg/dL, 2.4–3.6 mg/dL and coefficient of variation 1.9-2.9% and 1.7–3.7%, respectively. Accuracy measured 98–98.5%, satisfied acceptable criteria. Error grid analysis showed that all results of this study were in zone A. Hematocrit between 20% to 60% did not cause interference. Three of 24 interfering substances were not acceptable criteria, and dose-response evaluation was needed. CONCLUSIONS: This study showed that G400 was considered reliable results satisfying the ISO 15197:2013 criteria
