Purpose. One-piece titanium implants are not routinely used for reconstruction after tooth loss. Several limitations seemed to be apparent although the concept provides a straightforward approach for different clinical situations. A clinical documentation of five prosthetic restorations with one-piece titanium implants serving as a relevant treatment option in dental surgery is pursued. We demonstrate the feasibility and benefits of one-piece titanium implants for fixed dental prosthesis. Detailed descriptions of the technical features and the surgical approach by means of clinical cases are given. The prosthetic workflow when working with one-piece titanium implants is depicted in detail as well as examples for implant-supported tooth replacement in the posterior region and the esthetic zone. Conditions of applications regarding different timing of implant placement using the system and its limitations are discussed. Results. Clinical cases with a follow-up period of up to 10 years are presented to prove the long-term success of one-piece titanium implants in terms of bone and soft-tissue stability respecting the biological criteria for periodontal health. Conclusions. One-piece titanium implants represent a reliable treatment method for single-tooth replacements. Clinical success with long-time bone stability around the implantation site can be achieved. Taken into account the requirements for periodontal tissue stability, uneventful healing without extensive tissue loss is demonstrated by means of clinical cases presenting patients with periodontitis.

Background. The aim of this study was to evaluate the mid- to long-term outcomes of metatarsal head resurfacing hemiarthroplasty in the surgical treatment of advanced-stage hallux rigidus. Methods. We performed a retrospective review of 57 consecutive patients (25 [43.9%] males, 32 [56.1%] females; mean age, 61.0 ± 6.4 years) who underwent first metatarsal head resurfacing hemiarthroplasty (HemiCAP) for hallux rigidus between August 2007 and September 2010. Sixty-five implantations were performed in 57 patients; 8 patients underwent bilateral procedures. All patients were clinically rated prior to surgery and at the final follow-up visit using the American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale and first metatarsophalangeal joint range of motion (MTPJ ROM). Results. The median follow-up duration was 81 (range = 8-98) months. The median preoperative AOFAS score was 34 (range = 22-59) points, which had increased to 83 (range = 26-97) points at the final follow-up visit (P < .001). The median preoperative first MTPJ ROM was 25° (range = 15° to 40°), which had increased to 75° (range = 30° to 85°) at the final follow-up visit (P < .001). Conclusions. First MTPJ hemiarthroplasty is an effective treatment method that recovers toe function and first MTPJ ROM, and provides good mid- to long-term functional outcomes.

Lower Gi Bleeding

Introduction. We aimed to assess the efficacy and safety of digital subtraction angiography (DSA) and super-selective mesenteric artery embolization (SMAE) in managing lower GI bleeding (LGIB). Method. A retrospective case series of patients with LGIB treated with SMAE in our health service. Patients with confirmed active LGIB, on either radionuclide scintigraphy (RS) or contrast-enhanced multidetector CT angiography (CE-MDCT), were referred for DSA +/− SMAE. Data collected included patient characteristics, screening modality, bleeding territory, embolization technique, technical and clinical success, short-term to medium-term complications, 30-day mortality, and progression to surgery related to procedural failure or complications. Results. There were fifty-five hospital admissions with acute unstable lower gastrointestinal bleeding which were demonstrable on CE-MDCT or RS over a 31-month period. Eighteen patients proceed to embolization, with immediate success in all. Eight patients (44%) had clinical rebleeding after intervention, warranting repeated imaging. Only one case (5.6%) demonstrated radiological rebleeding and was reembolized. Complication rate was excellent: no bowel ischaemia, ischaemic stricture, progression to surgery, or 30-day mortality. Conclusion. SMAE is a viable, safe, and effective first-line management for localised LGIB. Our results overall compare favourably with the published experiences of other institutions. It is now accepted practice at our institution to manage localised LGIB with embolization.

Abstract Background Eravacycline (ERV) is a next-generation tetracycline approved for complicated intra-abdominal infections (cIAI) with in-vitro activity to multidrug-resistant organisms such as carbapenem resistant Enterobacteriaceae, extended spectrum beta-lactamase, and carbapenem-resistant Acinetobacter baumannii (CRAB). The purpose of this study was to identify the utility of ERV in clinical practice. Methods Retrospective case series was conducted on patients at AdventHealth that received at least two doses of ERV. Primary endpoint for the study was clinical success while on ERV, meeting none of the following criteria: changing therapy, mortality, or lack of improvement from sign/symptoms. Results Of 23 patients, 74% were males with a mean age of 55 ±18 years and mean body weight of 79 ±27 kg. Mean APACHE II and Charleson scores were 20 (±11) and 6 (±4), respectively. 91% received ERV for an off-label indication or organism. Infection types were respiratory (44%), cIAI (35%), skin (9%), and other (13%). All patients had positive cultures, while 61% were treated as a polymicrobial infection and 17% had bacteremia. Microorganisms included A. xylosoxidans, S. maltophilia, CRAB, and K pneumoniae. 48% had ERV susceptibilities from .06-4 mcg/mL, including two MIC ≥32mcg/mL for S. maltophilia. 70% were given another antibiotic prior to ERV with a median duration of 5 (1-35) days. Median duration of ERV was 8 (3-30) days. 83% percent received ERV in combination with another antibiotic. During treatment, 26% had a Child-Pugh Class C at baseline and 30% had elevated liver function tests. No adverse drug reactions were reported. Upon discharge, 35% continued ERV. Clinical success was observed in 57% (12/21) of patients. Clinical outcome by infection type is summarized in Figure 1. Of 9 cases of clinical failure, 14% were changed to alternative, 19% died while on ERV, and 10% failed to resolve signs/symptoms. Two cases of M. abscessus infections had insufficient follow-up to assess clinical outcome. Figure 1. Eravacycline Clinical Outcome by Infection Type Conclusion Initial real-world experience with ERV differs significantly from the trials regarding severity of illness, types of infection, and clinical outcomes. Further evaluation is necessary for using ERV as combination therapy and in off-label indications. Disclosures All Authors: No reported disclosures

Abstract Background and aims Current endoscopic methods of biliary decompression in malignant pancreatic neoplasms are often limited by anatomical and technical challenges. In this case series, we report our experience with endoscopic ultrasound (EUS)-guided placement of an electrocautery-enhanced, lumen-apposing self-expandable metallic stent (LAMS) via transmural gallbladder drainage. Methods This is a retrospective case series of nine patients (five male, mean age 63.1 years) who underwent EUS-guided LAMS placement for malignant, obstructive jaundice in the pancreatic head. All nine cases were performed by an experienced interventional endoscopist at a single, tertiary medical center. We review the technical and clinical success rates as well as the incidence of procedural adverse events across the nine patients. Results LAMS placement was technically successful in all cases and there were no procedural adverse events. Seven of nine (77.78 %) patients showed clinical and laboratory improvement immediately following the procedure. One case required re-intervention with interventional radiology guided biliary drain placement. The mean fluoroscopy time was 1.02 minutes. Conclusions EUS-guided LAMS placement for transmural gallbladder drainage in malignant obstruction appears to be a safe and effective technique, allowing patients to proceed to surgery, chemotherapy, or hospice care.

3D Printed

Background: The advancement of 3D printing technology has allowed for the use of custom-designed implants for difficult-to-treat foot and ankle pathologies. This study reports on the radiographic and functional outcomes of a case series of patients treated with patient-specific 3D-printed titanium implants. Methods: Fifteen consecutive patients treated with custom-designed 3D-printed implant cages for severe bone loss, deformity correction, and/or arthrodesis procedures were included in this study. A minimum of 1 year of clinical and radiographic follow-up was required. No patients were lost to follow-up. Patients completed a visual analog scale for pain, the Foot and Ankle Ability Measure Activities of Daily Living score, and the American Orthopaedic Foot & Ankle Society Score outcomes questionnaires preoperatively and at most recent follow-up. All patients had postoperative radiographs and computed tomography (CT) scans to assess bony incorporation. The mean age was 53.3 years (range, 22-74 years) with a mean follow-up of 22 months (range, 12-48 months) for these 15 patients. Results: Radiographic fusion verified by CT scan occurred in 13 of 15 patients. There was significant improvement in pain and all functional outcome score measures. All patients who went on to fusion were satisfied with their surgery. There were 2 failures, consisting of 1 infection and 1 nonunion, with an overall clinical success rate of 87%. Conclusion: These patients demonstrated the successful use of patient-specific 3D-printed titanium implants to treat complex large bony defects, deformities, and arthrodesis procedures. These implants offer surgeons a novel and promising approach to treat both lower extremity pain and deformity that is not always available with current techniques. Level of Evidence: Level IV, retrospective case series.

PICO question In dogs with medial shoulder instability, what treatment option results in the best patient outcomes medical vs. surgical management? Clinical bottom line To date only one retrospective case series is available to compare treatment options for shoudler instability. This manuscript suggests that surgical treatment of medial shoulder instability (MSI) may be superior to medical management, however, this was not a prospective randomly assigned study and thus is wrought with limitations. There is no evidence of superiority of one surgical intervention over another for the treatment of MSI. The clinician must evaluate each individual case and consider clincial experience when deciding on the ideal treatment for MSI. How to apply this evidence in practice The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources. Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care.
