9 and 72.2 units per 100 patients, respectively), and were hospitalized longer (grade 1 median 15; grade 3 median 40 days). Mortality rates did not significantly differ. Stratification analyses did not reveal effect modifiers for the association between wound grades and patient outcomes.

The Red Cross wound grade of a pediatric patient's extremity wound correlates independently with treatment needs. This simple wound grading system could support clinical decision-making and should be integrated into the clinical assessment of weapon-wounded pediatric patients in conflict settings.

Thrombospondin-1 (TSP-1), a Ca
-binding trimeric glycoprotein secreted by multiple cell types, has been implicated in the pathophysiology of several clinical conditions. Signaling involving TSP-1, through its cognate receptor CD47, orchestrates a wide array of cellular functions including cytoskeletal organization, migration, cell-cell interaction, cell proliferation, autophagy, and apoptosis. In the present study, we investigated the impact of TSP-1/CD47 signaling on Ca
dynamics, survival, and deformability of human red blood cells (RBCs).

Whole-cell patch-clamp was employed to examine transmembrane cation conductance. RBC intracellular Ca
levels and multiple indices of RBC cell death were determined using cytofluorometry analysis. RBC morphology and microvesiculation were examined using imaging flow cytometry. RBC deformability was measured using laser-assisted optical rotational cell analyzer.

Exposure of RBCs to recombinant human TSP-1 significantly increased RBC intracellular Ca
levels. As judged by electrophysiology experiments, TSP-1 treatment elicited an amiloride-sensitive inward current alluding to a possible Ca
influx via non-selective cation channels. Exogenous TSP-1 promoted microparticle shedding as well as enhancing Ca
- and nitric oxide-mediated RBC cell death. Monoclonal (mouse IgG1) antibody-mediated CD47 ligation using 1F7 recapitulated the cell death-inducing effects of TSP-1. WRW4 Furthermore, TSP-1 treatment altered RBC cell shape and stiffness (maximum elongation index).

Taken together, our data unravel a new role for TSP-1/CD47 signaling in mediating Ca
influx into RBCs, a mechanism potentially contributing to their dysfunction in a variety of systemic diseases. Video abstract.

It has been reported that HCN channels are expressed in the spinal cord, but knowledge about their physiological roles, as well as their distribution profiles, appear to be limited. We generated a transgenic mouse in which the expression of HCN4 can be reversibly knocked down using a genetic tetracycline-dependent switch and conducted genetically validated immunohistochemistry for HCN4. We found that the somata of HCN4-immunoreactive (IR) cells were largely restricted to the ventral part of the inner lamina II and lamina III. Many of these cells were either parvalbumin- or protein kinase Cγ (PKCγ)-IR. By using two different mouse strains in which reporters are expressed only in inhibitory neurons, we determined that the vast majority of HCN4-IR cells were excitatory neurons. Mechanical and thermal noxious stimulation did not induce c-Fos expression in HCN4-IR cells. PKCγ-neurons in this area are known to play a pivotal role in the polysynaptic pathway between tactile afferents and nociceptive projection cells that contributes to tactile allodynia. Therefore, pharmacological and/or genetic manipulations of HCN4-expressing neurons may provide a novel therapeutic strategy for the pain relief of tactile allodynia.
The increasing popularity of alpacas and llamas outside of South America is undeniable. The associated limited genetic diversity raises questions about health and other genetically determined traits like coat colour. Therefore, a survey studying the prevalence of congenital disorders and coat colours and patterns in South American camelids was performed in Austria, Germany and Switzerland. Moreover, the motivation for keeping these animals, the herd size and breeds was assessed.

A total of 146 questionnaires were returned corresponding to 16 farms from Austria, 69 farms from Germany, and 61 farms from Switzerland. In total, the returned surveys reported data on 2770 animals including ~ 85% alpacas and ~ 15% llamas. The most common alpaca breed was Huacaya (87.7%), the most common llama breed was Wooly (15.6%). Breeding (69.4%), wool production (63.3%) and keeping them as pets (53.7%) were the most common motivations to keep these animals, although this varied among countries. The three coat colour groups, musculoskeletal disorders might encourage the breeders to eliminate affected animals from their breeding program to decrease the incidence although traits such as spiral toe growth might also represent phenocopies.
This survey revealed first insights into the occurrence of different traits and disorders in the current South American camelid population of Austria, Germany, and Switzerland. The identification of the most common musculoskeletal disorders might encourage the breeders to eliminate affected animals from their breeding program to decrease the incidence although traits such as spiral toe growth might also represent phenocopies.
Ganglioneuromas (GNs) are extremely rare, slowly growing, benign tumors that can arise from Schwann cells, ganglion cells, and neuronal or fibrous tissues. Due to their origin from the sympathetic neural crest, they show neuroendocrine potential; however, most are reported to be hormonally inactive. Nevertheless, complete surgical removal is recommended for symptom control or for the prevention of potential malignant degeneration.

A 30-year-old female was referred to our oncologic center due to a giant retroperitoneal and mediastinal mass detected in computed tomography (CT) scans. The initial symptoms were transient nausea, diarrhea, and crampy abdominal pain. There was a positive family history including 5 first- and second-degree relatives. Presurgical biopsy revealed a benign ganglioneuroma. Total resection (TR) of a 35 × 25 × 25 cm, 2550-g tumor was obtained successfully via laparotomy combined with thoracotomy and partial incision of the diaphragm. Histopathological analysis confirmed the diagnosis.
