The effect of humeral tray thickness on glenohumeral loads in a reverse shoulder 'smart' implant.

Purpose: The aim of this study was to observe the effects of changing humeral tray thickness on the resultant of intraoperative glenohumeral joint loads using a load-sensing system (LSS).

Methods: An rTSA was performed on fresh frozen full-body cadaver shoulders by using an internal proprietary LSS on the humeral side. The glenohumeral loads (Newtons) and the direction of the resultant force applied on the implant were recorded during four standard positions (External rotation, Extension, Abduction, Flexion) and three "complex" positions of Activity Daily Life ("behind back", "overhead reach" and "across chest").

'Mini DC-F' in rhinoplasty: Diced cartilage and fascia grafts with the temporalis fascia dissected along its width - A technical note.

In rhinoplasty, diced cartilage with fascia (DC-F) is a commonly used technique to enhance dorsal projection and achieve a smooth dorsum. We have developed a modified technique by dissecting the thickness of the fascia along its width, called "Mini DC-F". This method allows for effective camouflaging of dorsal irregularities and provides a slight increase in dorsal height.

Training for a mass casualty incident: Conception, development, and implementation of a crew-resource management course for forward surgical teams.

Background: Since 2021, the predeployment training of French FSTs has included a simulation-based curriculum consisting of organizational and human factors. The purpose of this article is to describe the development of a crew-resource management (CRM) training course dedicated for the forward surgical teams (FSTs) of the French Military Health Service.

Methods: The approach was based on three steps: (1) establishment of a conceptual framework of FSTs deployment; (2) development of an aircrew-like CRM training combining lectures, laboratory exercises, and situational training exercises to consider four fundamental "nontechnical" (cognitive and social) skills for effective and safe combat casualty care: (a) leadership, (b) decision-making, (c) coordination, and (d) situational awareness; (3) Implementation of teamwork evaluation tools.

Nonaneurysmal perimesencephalic subarachnoid hemorrhage on noncontrast head CT: An accuracy, inter-rater, and intra-rater reliability study.

Background And Purpose: To evaluate the reliability and accuracy of nonaneurysmal perimesencephalic subarachnoid hemorrhage (NAPSAH) on Noncontrast Head CT (NCCT) between numerous raters.

Materials And Methods: 45 NCCT of adult patients with SAH who also had a catheter angiography (CA) were independently evaluated by 48 diverse raters; 45 raters performed a second assessment one month later. For each case, raters were asked: 1) whether they judged the bleeding pattern to be perimesencephalic; 2) whether there was blood anterior to brainstem; 3) complete filling of the anterior interhemispheric fissure (AIF); 4) extension to the lateral part of the sylvian fissure (LSF); 5) frank intraventricular hemorrhage; 6) whether in the hypothetical presence of a negative CT angiogram they would still recommend CA.

Return to Sport and Duty in French Military Personnel After Medial Opening Wedge High Tibial Osteotomy.

Introduction: Medial opening wedge high tibial osteotomy (MOWHTO) is a surgical option for medial femorotibial osteoarthritis, which preserves articular cartilage by correcting the extra-articular deformities of the lower limbs that cause osteoarthritis. This is an increasingly popular treatment in a population with high functional demand, such as the French military population. The aim of this study was to evaluate the rate of return to work and military activities at 6 months postsurgery and at last follow-up in this military population following MOWHTO.

Therapeutic management of severe spinal cord decompression sickness in a hyperbaric center.

Introduction: Spinal cord decompression sickness (scDCS) unfortunately has a high rate of long-term sequelae. The purpose of this study was to determine the best therapeutic management in a hyperbaric center and, in particular, the influence of hyperbaric treatment performed according to tables at 4 atm (Comex 30) or 2.8 atm abs (USNT5 or T6 equivalent).

ABO blood type and functional neurological outcome in patients with severe traumatic brain injury.

Background: The ABO blood system has been involved in the pathogenesis of several diseases, including coagulopathy and bleeding complications. In trauma patients, blood type A has been associated with acute respiratory distress syndrome, and recently, blood type O has been associated with all-cause mortality. The purpose of this study was to assess the association between ABO blood types and long-term functional outcomes in critically ill patients with severe traumatic brain injury (TBI).

Neurosurgical Consultation Referral from the Forces: Regarding 328 Patients Referred to the Department of Neurosurgery, Sainte Anne Military Hospital, France.

Introduction: There are little data regarding elective referral to the military specialist, especially considering common pathologies such as spinal diseases, which, in the French forces, involve military neurosurgeons. An overview of the management of the military patient referred to neurosurgery consultation, especially considering spinal diseases that both constitute an operational healthissue in the forces and appear of special interest. The objective was to describe the reasons, demographics, and care pathways, addressed to the neurosurgeon.

Retinal Pigment Epithelium Tear After Nonpenetrating Deep Sclerectomy.

Retinal pigment epithelium (RPE) tear is a common complication in the context of neovascular age-related macular degeneration treated by intravitreal injections of antivascular endothelial growth factor drugs. There are some reports of such complications after trabeculectomy but none after nonpenetrating deep sclerectomy (NPDS). A 57-year-old man presented to our hospital with uncontrolled advanced glaucoma of his left eye.

Symptomatic or asymptomatic SAR-CoV-2 positive divers should be medically evaluated before returning to scuba diving.

In order to allow the resumption of diving activities after a COVID-19 infection, French military divers are required to undergo a medical fitness to dive (FTD) assessment. We present here the results of this medical evaluation performed 1 month after the infection. We retrospectively analyzed between April 2020 and February 2021 200 records of divers suspected of COVID-19 contamination.

Outpatient management of facial fractures in France: Current state.

Maxillofacial trauma is still very common in France with possible involvement of all face bones. Outpatient surgery is an axis strongly put forward by the public authorities. The aim of this study is to establish a current state in the outpatient management of facial fractures in France in 2019 before COVID infection.

Emergency Cranial Surgeries Without the Support of a Neurosurgeon: Experience of the French Military Surgeons.

Introduction: Unlike orthopedic or visceral surgeons, French military neurosurgeons are not permanently deployed on the conflict zone. Thus, craniocerebral war casualties are often managed by general surgeons in the mobile field surgical team. The objective of the study was to provide the feedback of French military surgeons who operated on craniocerebral injuries during their deployment in a role 2 surgical hospital without a neurosurgeon.

Granulocyte microvesicles with a high plasmin generation capacity promote clot lysis and improve outcome in septic shock.

Microvesicles (MVs) have previously been shown to exert profibrinolytic capacity, which is increased in patients with septic shock (SS) with a favorable outcome. We, therefore, hypothesized that the plasmin generation capacity (PGC) could confer to MVs a protective effect supported by their capacity to lyse a thrombus, and we investigated the mechanisms involved. Using an MV-PGC kinetic assay, ELISA, and flow cytometry, we found that granulocyte MVs (Gran-MVs) from SS patients display a heterogeneous PGC profile driven by the uPA (urokinase)/uPAR system.

Long-term surgical oncological and functional outcome of large petroclival and cerebellopontine angle epidermoid cysts: a multicenter study.

Cranial nerve (CN) disorders are the foremost symptoms in cerebellopontine angle (CPA) and petroclival area (PCA) epidermoid cysts (EC).The aim of this work was to  assess the long-term surgical results on CN function and tumor control in these patients. We performed a retrospective cohort study about 56 consecutive patients operated on for a CPA or PCA EC between January 2001 and July 2019 in six participating French cranial base referral centers.

Acute Myocarditis after COVID-19 vaccination: A case report.

Introduction: The etiology of myocarditis often remains undetermined. A large variety of infectious agents, systemic diseases, drugs, and toxins can cause the disease. We report the case of a 19-year-old man who developed myocarditis three days after Pfizer-BioNTech COVID-19 booster vaccination.
