Diabetic patients showed comparable clinical results with non-diabetic patients post-ARCR. Perioperative diabetic control may be recommended for preoperatively uncontrolled diabetic patients.

Although several causes of ligamentum flavum (LF) hypertrophy have been identified, the pathomechanisms underlying LF hypertrophy are not fully understood. Because collagen fibers are essential for the maintenance of LF tissues, characterization of the collagen composition of hypertrophied LF may help to elucidate the pathology of lumbar spinal canal stenosis (LCS). This study aimed to determine the association between the collagen composition and LF hypertrophy.

LF tissues were collected from 23 patients who underwent spinal decompression surgery for lumbar disorders. The cross-sectional area of LF was measured using the axial images of lumbar MRI. The expression of each collagen in human surgical samples was evaluated by real-time RT-PCR and immunohistochemical analysis. To investigate the impact of inflammatory cytokines on the expression of each collagen, we treated primary human LF cells with TNF-α or IL-1β.

Real-time RT-PCR analysis and immunohistochemistry showed that of the 28 types of collagen,LF hypertrophy and even LCS.

Our objective was to review recent drug and medical device recalls, categorize recall types based on the free text descriptions posted within the recall announcements, and conduct exploratory analyses for researchers interested in pharmaceutical supply chain challenges.

A cross-sectional study of all current recalls, market withdrawals, and safety alerts published by the United States Food and Drug Administration pertaining to drugs was conducted. A manual review of all the recalls was also conducted to extract additional information including company details, recall type (labeling or quality), and location of failure in the pharmaceutical supply chain (manufacturing or distribution). Descriptive statistics and exploratory bivariate analyses were conducted to test any potential differences between drug and device recalls.

Most recalls issued between January 2017 and September 2019 were pharmaceutical drug recalls (85.2%), while 34 (14.8%) medical device recalls were issued for the same period. For drug recalls, 85.1% (166/195) were because of quality, while 14.9% (29/195) were because of labeling issues. Of the quality issues for drug recalls, lack of sterility was the most frequent issue (139/166, 83.7%). There was no difference between drug or device recalls based on recall type (P= 0.16), top 20 pharmaceutical company (P= 0.62), or location of the supply chain failure (P= 0.20).

This study provides a process to categorize and evaluate drug and device recalls by recall type and location of the supply chain. By categorizing the free text provided in public recall data it would be easier to monitor trends over time.

Extended knowledge of vascular anatomy has propagated the development of this innovative procedure, in the objective of reducing morbidity. The existence of close to 400 perforator vessels in the body makes it possible to offer new flap perspectives for many defects, which were sometimes previously impossible to manage before except by free flap. For us, perforator flaps have become the current first-line solutions for small to medium size loss of substances. Understanding of vascular physiology and surgical experience are essential in choosing indications, detecting perforators, and modeling flaps to be optimally positioned in the reconstructive decisional algorithm. New skills are needed to master this type of reconstruction and limit failures, which implies a learning curve not only for flap design, perforator detection and surgical procedure, but also for monitoring and management of complications. In this manuscript, we outline the concepts and principles of the majority of the pedicled perforator flaps available for coverage of the lower limb, based on experience of more than 400 perforator flaps suitable for this localization.The purpose of this technical note is to illustrate a simple and economical preoperative method for preshaping a reconstructive titanium plate in a fibula free flap (FFF) by using 3D printing of a virtually reconstructed mandible haptic model. The whole process consisted in creating a 3D model of the patient's mandible based on a CT-scan using a combination of free software (3Dslicer and ITK-snap), and simulating the surgical osteotomies and reconstruction, and print it as a guide for bending a reconstruction titanium plate. Reconstruction is performed using virtual cubes (1 to 3 cubes, according the number of FFF osteotomies). This virtual lab work is performed using 3D Builder® (Microsoft, Redmond) software. This technique allows obtaining an optimal plate application on the bony fragments. Mdivi-1 research buy It facilitates reconstructive surgery with good functional (putting the patient back in an optimal dental occlusion based on the native maxilla) and aesthetic results. This technical note presents a simple and economical preoperative fabrication of a reconstructive plate through freeware and a low-cost 3D printer accessible to all surgeons.Treatment of traumatic loss of bone and tissue substance in the foot necessitates special consideration of the anatomy and physiology of the segment. The causes of foot trauma are multiple and in many cases violent, leading to progressive tissue deterioration that may require multi-phased debridement. The therapeutic objective is to reconstruct a functional foot permitting painless pushing off, walking and footwear use by restoring a stable bone framework, with resistant covering satisfactorily adjusted to the different zones of the foot. While coverage of the back of the foot must be fine, coverage of the plantar zones will be padded. The reconstructive surgeon shall be particularly attentive to plantar sensitivity. To take up the surgical challenge, it is of paramount importance to fully master a wide-ranging therapeutic arsenal ranging from conventional grafts to composite free flaps in view of proposing the solution most suited to the type, size and location of the loss of substance, all the while striving to generate as few sequelae as possible at the donor site.
