First Time

For many years, the experience of neurosurgeons from the German Armed Forces was limited to the peacetime care of patients in Germany. In 1995, German military neurosurgeons were deployed abroad for the first time. Since the beginning of the International Security Assistance Force mission, there has been a rapidly increasing number of opportunities for military neurosurgeons to broaden their experience during deployments abroad. Since the first deployment of a neurosurgeon to the German field hospital in Mazar-e-Sharif, Afghanistan, a total of 140 neurosurgical procedures have been performed there. Sixty-four surgeries were performed for cranial or spinal neurotrauma management. During the entire period, only 10 International Security Assistance Force members required acute or urgent neurosurgical interventions. The majority of neurosurgical procedures were performed in Afghan patients who received acute and elective treatment whenever the necessary infrastructure was available in the field hospital. Fifteen patients from the Afghan National Army and Police and 115 local patients underwent neurosurgery. Sixty-two procedures were carried out under acute or urgent conditions, and 78 operations were elective.

Abstract BACKGROUND The cellular surface molecule HsTOSO/FAIM3/HsFcμR has been identified as an IgM-specific Fc receptor expressed on lymphocytes. Here, we show that its extracellular immunoglobulin-like domain (HsFcμR-Igl) specifically binds to IgM/antigen immune complexes (ICs) and exploit this property for the development of novel detection systems for IgM antibodies directed against Crimean-Congo hemorrhagic fever virus (CCHFV) and Zika virus (ZIKV). METHODS His-tagged HsFcμR-Igl was expressed in Escherichia coli and purified by affinity chromatography, oxidative refolding, and size-exclusion chromatography. Specific binding of HsFcμR-Igl to IgM/antigen ICs was confirmed, and 2 prototypic ELISAs for the detection of anti-CCHFV and anti-ZIKV IgM antibodies were developed. Thereby, patient sera and virus-specific recombinant antigens directly labeled with horseradish peroxidase (HRP) were coincubated on HsFcμR-Igl-coated ELISA plates. Bound ICs were quantified by measuring turnover of a chromogenic HRP substrate. RESULTS Assay validation was performed using paired serum samples from 15 Kosovar patients with a PCR-confirmed CCHFV infection and 28 Brazilian patients with a PCR-confirmed ZIKV infection, along with a panel of a priori CCHFV/ZIKV-IgM-negative serum samples. Both ELISAs were highly reproducible. Sensitivity and specificity were comparable with or even exceeded in-house gold standard testing and commercial kits. Furthermore, latex beads coated with HsFcμR-Igl aggregated upon coincubation with an IgM-positive serum and HRP-labeled antigen but not with either component alone, revealing a potential for use of HsFcμR-Igl as a capture molecule in aggregation-based rapid tests. CONCLUSIONS Recombinant HsFcμR-Igl is a versatile capture molecule for IgM/antigen ICs of human and animal origin and can be applied for the development of both plate- and bead-based serological tests.
