Nine years of surgical activity in the deployed French military role 2 medical treatment facility in Mali.

INTRODUCTION: In January 2013, France launched a military operation in Mali, which ended in August 2022. This study aimed to analyse the global activity performed by a surgical team within the role 2 medical treatment facility (MTF) deployed in Gao during this period, in order to adapt medical battlefield support and combat casualty care teaching. METHODS: A retrospective study was conducted using the French surgical database OpEX (French Military Health Service) from January 2013 to August 2022. All patients operated on were included. RESULTS: During this period, 1298 patients with a median age of 29 (range: 23-38) years were included. Among them, 229 (17.6%) underwent a combat-related trauma surgery (CRTS), 234 (18.0%) underwent a non-CRTS, 167 (12.9%) underwent a non-trauma-related surgery and 668 (51.5%) underwent a scheduled surgery in the context of medical supply to the population.Among the CRTS group, 195 (85.2%) patients underwent an orthopaedic procedure, 73 (31.8%) required a general surgery. Finally, 15 (6.6%) wounded required a specialised surgery. CONCLUSIONS: In line with the activity described in the role 2 MTF deployed in other contemporary asymmetric conflicts, this activity is moderate, especially if only combat-related injuries are considered; medical support to the population occupied most of the surgical activity. For CRTS, most of the traumas are limb traumas. Other traumas are composed of various lesions, which are often life-threatening. This fact imposes the presence of an orthopaedic surgeon with the appropriate equipment, as well as a general surgeon with a wide range of skills, in asymmetric conflicts.

Rituximab in routine care of severe active rheumatoid arthritis : A prospective, non-interventional study in Germany.

OBJECTIVE: To assess safety, effectiveness and onset of effect of rituximab (RTX) in routine clinical treatment of severe, active rheumatoid arthritis (RA). METHODS: Prospective, multi-centre, non-interventional study in rheumatological outpatient clinics or private practices in Germany. RTX-naïve adult patients were to receive RTX according to marketing authorisation and at their physician's discretion. Also according to their physician's discretion, patients could receive a second cycle of RTX (re-treatment = treatment continuation). Major outcome was the change in Disease Activity Score based on 28-joints count and erythrocyte sedimentation rate (DAS28-ESR) over 24 weeks and during 6 months of re-treatment. RESULTS: Overall, 1653 patients received at least one cycle RTX; 99.2% of these had received disease-modifying antirheumatic drugs (DMARD) pre-treatment and 75.5% anti-tumor necrosis factor(TNF)­α pre-treatment. After a mean interval of 8.0 months, 820 patients received RTX re-treatment. Mean DAS28-ESR decreased from 5.3 at baseline to 3.8 after 24 weeks (-1.5 [95% confidence interval, CI: -1.6; -1.4]), and from 4.1 at start of cycle 2 to 3.5 at study end (change from baseline: -1.8 [95% CI: -2.0; -1.7]). Improvements in DAS28-ESR and Health Assessment Questionnaire (HAQ) score occurred mainly during the first 12 weeks of RTX treatment, with further DAS28-ESR improvement until week 24 or month 6 of re-treatment. Improvements in DAS28-ESR and EULAR responses were more pronounced in seropositive patients. RF was a predictor of DAS28-ESR change to study end. Safety analysis showed the established profile of RTX. CONCLUSION: RTX was safe and effective in a real-life setting with rapid and sustained improvement in RA signs and symptoms.

Hyperacusis in chronic pain: neural interactions between the auditory and nociceptive systems.

OBJECTIVE: Sensory disturbances are common in chronic pain patients. Hyperacusis can be an especially debilitating experience. Here, we review published work on how the auditory and nociceptive systems might interact in chronic pain syndromes to produce pain-hyperacusis. DESIGN: Literature review. STUDY SAMPLE: The PubMed and Scopus databases were searched for relevant articles published between 2000 and 2017 using the primary search terms "hyperacusis"/"hyperacousis" and "pain". Ten papers were found using this strategy. Supplementary sources were identified by browsing textbooks and the reference lists of identified articles. RESULTS: The importance of central mechanisms in pain-hyperacusis was highlighted in the 10 selected papers. Hyperacusis is a significant but under-recognised symptom in conditions such as complex regional pain syndrome and fibromyalgia, and an integral feature of migraine. CONCLUSIONS: Nociceptive circuits become hypersensitive in acute and chronic pain; this sensitivity spreads from the periphery to spinal neurons and higher centres in the brain, leading to hyperalgesia or spontaneous pain even in the absence of peripheral nociceptive input. This "central sensitisation" may alter activity at sensory convergence points in the thalamus and brainstem centres such as the locus coeruleus, and give rise to hyperacusis in certain pain syndromes.

[Report on the 34th meeting of the German Clinical Immunology Workgroup, Frankfurt, 03.-04.11.2006]. / Bericht über die 34. Tagung des Arbeitskreises Klinische Immunologie, Frankfurt, 03.-04.11.2006.

The annual meeting of the Clinical Immunology Workgroup focused on autoimmune vasculitides. The role of innate immunity, T- and B-cells, and innovative therapies for autoimmune vasculitides was discussed. Further topics of the meeting were the role of endothelial microparticles, ghrelin and leptin, regulatory and effector-memory T-cells in ANCA-associated vasculitides, as well as the lethal midline granuloma, intracytoplasmic cytokine-profile in Behcet's disease, autoantibodies in rheumatoid arthritis, polyarteritis nodosa with cranial manifestation, ILT6 as genetic marker in multiple sclerosis and Sjögren's syndrome, alpha-fodrin autoantibodies in multiple sclerosis, interferon-g autoantibodies in a patient with atypical mycobacteriosis, and autoreactive T-cells in murine lupus.

Lack of efficacy of rituximab in Wegener's granulomatosis with refractory granulomatous manifestations.

OBJECTIVE: To investigate the safety and efficacy of rituximab (RTX) in patients with refractory Wegener's granulomatosis (WG). PATIENTS AND METHODS: Eight consecutive patients with active refractory WG were included. In all patients disease activity had persisted despite standard treatment with cyclophosphamide and prednisolone, as well as tumour necrosis factor alpha blockade 3 months before inclusion in the study. Patients had particular granulomatous manifestations like retro-orbital granulomata (n=5), nodules of the lungs (n=1), and subglottic stenosis (n=2). RTX was given intravenously every 4th week in combination with the standard treatment in five patients and with methotrexate in two others. Disease extent and activity were monitored clinically by interdisciplinary care, immunodiagnostics (ANCA serology, B cells by flow cytometry), and magnetic resonance imaging. RESULTS: Beneficial response and a reduction in disease activity were seen in three patients, two of whom went into complete remission. In three other patients, disease activity remained unchanged while the disease progressed in the remaining two patients. In all patients peripheral blood B cells fell to zero during treatment with RTX. cANCA titres remained unchanged in all except one patient. CONCLUSION: In this pilot study, B lymphocyte depletion was not associated with a change of the ANCA titres or obvious clinical improvement of refractory granulomatous disease in patients with WG. Further studies are needed to evaluate the role of RTX in WG.

[Early diagnosis of vasculitides]. / Frühdiagnose von Vaskulitiden.

The often unspecific symptoms like myalgias, fever and weight loss at the onset of vasculitides are a frequent cause for a delay in diagnosis. Organ-specific symptoms like hemoptysis, dyspnoea, epistaxis, edema and organ infarcts a present when organ dysfunction occurs as a result of vasculitis. Targeted serologic testing including antineutrophil cytoplasm antibodies (ANCA) and cryoglobulins allows early diagnosis of certain vasculitides. Modern imaging techniques like magnetic resonance imaging, computed tomography, positron-emission tomography and ultrasound are cornerstones for an early diagnosis as they allow the detection of subclinical disease and are helpful in the identification of a site for biopsy. Bioptic proof of vasculitis is still the gold standard for diagnosis. Functionally relevant damage caused by systemic inflammatory disorders can by reduced or sometimes avoided by early initiation of treatment. This requires a correct diagnosis is made as early as possible.

[Symmetric polyarthritis in a patient with Churg-Strauss syndrome]. / Symmetrische Polyarthritis bei einem Patienten mit Churg-Strauss-Syndrom.

HISTORY: A 63-year-old man developed a Churg-Strauss syndrome with predominantly motor-sensory polyneuropathy. Initial treatment with cyclophosphamide and steroids achieved complete remission. Subsequent relapse with marked retinal vasculitis at first was refractory to the standard treatment. Renewed remission was obtained with additional infliximab, and was maintained with azathioprine for 12 months before the patient again presented with symmetrical polyarthritis. INVESTIGATIONS: Clinical examination revealed a symmetrical polyarthritis involving the joints of the hand and fingers. The acute-phase parameters were raised, the rheumafactor was highly positive. Radiology showed early erosions in the bones of the hand. There were no indices of renewed activity of the Churg-Strauss syndrome. TREATMENT AND COURSE: These findings indicated sero-positive rheumatoid arthritis and methotrexate was started, later supplemented with sulfsalazine and hydroxychloroquine because of continuing signs of activity. Infliximab was again given because of further progression, but a severe infusion reaction developed during the second infusion. After changing to etanercept remission of the rheumatoid arthritis was achieved. CONCLUSION: The development of rheumatoid arthritis during remission achieved with azathioprine in Churg-Strauss syndrome of four-year duration is very rare. Repeated dosis of infliximab at long intervals greatly increases the risk of an intolerance.
