Outcomes of partial fundoplication for GERD-related allograft decline after lung transplantation.

INTRODUCTION: Gastroesophageal reflux disease contributes to allograft decline secondary to bronchiolitis obliterans after lung transplantation. Antireflux surgery (ARS) slows the decline in lung function related to GERD. ARS operations range from Nissen fundoplications to partial fundoplications, such as the Toupet and Dor. Research in the general population has indicated that partial fundoplication is effective at controlling reflux. We explored lung function and reflux outcomes in a cohort of lung transplant patients who received partial fundoplications. METHODS: Data from an institutional lung transplant registry was reviewed for patients between 2009 and 2020 who underwent fundoplication after transplant. Lung transplant patients underwent routine pulmonary function testing. Patients with FEV1 values within 180 days pre-fundoplication and two years post-fundoplication were included in the analysis. All patients referred for fundoplication underwent esophageal pH testing, manometry, UGI, and EGD. Most patients underwent Toupet fundoplication, but those with severe dysmotility underwent Dor fundoplication. RESULTS: 53 patients were included in the analysis. Median time to fundoplication after transplant was 403 days. 48 patients underwent Toupet fundoplication. Five underwent Dor fundoplication. 40% of patients had abnormal high-resolution manometry. A linear mixed-effects model tested for a change in FEV1 trajectory up to two years post-fundoplication with an auto-regressive correlation structure. Post-fundoplication FEV1 values decreased by 7 mL per month, and suggested a slow in the decline by 2 mL per month, but this was not significant (p = 0.8). In patients for whom postoperative DeMeester scores were available (19), there was a decline in acid exposure from a median of 45.8 to 1.8 after ARS (p = 0.0003). CONCLUSION: Although our results did not reach statistical significance, there was a trend towards a decrease in the rate of decline of allograft function before and after partial fundoplication. In the patients whom results were available, a partial fundoplication appropriately controlled acid exposure.

Enhancing aesthetic outcomes of soft-tissue coverage of the hand.

Hand aesthetics in general and aesthetic refinements of soft-tissue coverage of the hand in particular have been increasingly considered over the past few years. Advancements of microsurgery together with the traditional methods of tissue transfer have expanded the number of techniques available to the reconstructive surgeon, thus shifting the reconstructive paradigm from simply "filling the defect" to reconstructive refinement to provide the best functional and aesthetic results. However, drawing the boundary between what does and what does not constitute "aesthetic" reconstruction of the hand is not straightforward. The selection among the vast amount of currently available reconstructive methods and the difficulties in objectively measuring or quantifying aesthetics have made this task complex and rather arbitrary. In this article, the authors divide the hand into several units and subunits to simplify the understanding of the basic functional and aesthetic requirements of these regions that may ultimately bring order to complexity.

The art and science of photography in hand surgery.

High-quality medical photography plays an important role in teaching and demonstrating the functional capacity of the hands as well as in medicolegal documentation. Obtaining standardized, high-quality photographs is now an essential component of many surgery practices. The importance of standardized photography in facial and cosmetic surgery has been well documented in previous studies, but no studies have thoroughly addressed the details of photography for hand surgery. In this paper, we provide a set of guidelines and basic camera concepts for different scenarios to help hand surgeons obtain appropriate and informative high-quality photographs. A camera used for medical photography should come equipped with a large sensor size and an optical zoom lens with a focal length ranging anywhere from 14 to 75 mm. In a clinic or office setting, we recommend 6 standardized views of the hand and 4 views for the wrist; additional views should be taken for tendon ruptures, nerve injuries, or other deformities of the hand. For intraoperative pictures, the camera operator should understand the procedure and pertinent anatomy in order to properly obtain high-quality photographs. When digital radiographs are not available and radiographic film must be photographed, it is recommended to reduce the exposure and change the color mode to black and white to obtain the best possible pictures. The goal of medical photography is to present the subject in an accurate and precise fashion.

The outcomes movement and evidence-based medicine in plastic surgery.

Evidence-based medicine is analyzed from its inception. This article takes the reader through the early formation of scientific medicine that has evolved into the multipurpose tool it has become today. Early proponents of evidence-based medicine and the outcomes movement, and their intentions, are presented. The work of David Sackett, Gordon Guyatt, Florence Nightingale, Ernest Codman, and Archie Cochrane is discussed, regarding how they perceived the need for better clinical outcomes that led to a more formalized evidence-based practice. The fundamentals are discussed objectively in detail, and potential flaws are presented that guide the reader to deeper comprehension.

The epidemiology of distal radius fractures.

Distal radius fractures are one of the most common types of fractures. Although the pediatric and elderly populations are at greatest risk for this injury, distal radius fractures still have a significant impact on the health and well-being of young adults. Data from the past 40 years have documented a trend toward an overall increase in the prevalence of this injury in both the pediatric and elderly populations. Understanding the epidemiology of this fracture is an important step toward the improvement of treatment strategies and the development of preventive measures with which to target this debilitating injury.

Impairment and disability: Renoir's adaptive coping strategies against rheumatoid arthritis.

Pierre-Auguste Renoir was one of the most influential painters in art history, but few people know that he suffered from debilitating rheumatoid arthritis. Despite his arthritis, he was able to maintain an incredible level of precision and efficiency with his painting. More importantly, he remained positive and did not let his condition affect his passion for painting or take away from the beauty that he saw in the world around him. Renoir applied a wide variety of coping mechanisms and used his ingenuity to come up with different ways to continue painting even as his arthritis weakened him. Renoir's long battle with rheumatoid arthritis serves as an inspiration to patients who experience the pain and limited mobility associated with this disease, encouraging them to persevere and to develop coping mechanisms that prevent the effects of their impairment from disabling them.

Presence and density of Helicobacter pylori biofilms in human gastric mucosa in patients with peptic ulcer disease.

Our purpose was to use endoscopically directed biopsies and scanning electron microscopy to quantify Helicobacter pylori biofilm density on the surface of human gastric mucosa in urease-positive and -negative patients. Participating patients underwent flexible esophago-gastro-duodenoscopies coupled with gastric mucosal biopsies. Rapid urease testing was performed on all specimens to determine the presence of H. pylori, followed by scanning electron microscopy to identify the existence of biofilms. Samples were then analyzed using Carnoy Image Analysis Software to determine percent biofilm coverage of the total surface area. These data were compared to control specimens that were urease negative. Of the patients who tested urease positive for H. pylori, the average percent of total surface area covered by biofilms was 97.3%. Those testing negative had an average surface area coverage of only 1.64%. These differences were determined to be statistically significant at the 0.0001 level. This study demonstrates that compared with controls, urease-positive specimens have significant biofilm formation, whereas urease-negative specimens have little to none. This was reflected in the significantly increased biofilm surface density in urease positive specimens compared with urease-negative controls.
