Clinicopathological Profile of Myelomatous Pleural Effusion: Single-center Real-world Experience and Review of Literature

Background

Multiple myeloma (MM) is a hematologic malignancy of plasma cell origin. MM primarily affects bone marrow, but extramedullary sites can also be involved. Myelomatous pleural effusion (MPE) is an atypical and rare complication of MM. We aimed to systematically study the incidence and clinicopathologic profile of patients with MPE in a real-world setting.

Die Akutversorgung von Brandverletzten

Burn injuries can be caused by thermal, electrical, chemical, or mechanical trauma or radiation and are relatively rare, as they represent only about 1% of all emergencies. They are caused by accidents at home, during recreational activities, or in the occupational environment. Minor burn traumas are much more common than severe burn injuries with their systemic and potentially life-threatening effects. Altogether, these circumstances may result in a lack of routine for treating such injuries properly by physicians and their colleagues in the emergency room or intensive care unit. A clearly outlined concept for preclinical and clinical treatment can be the keystone of successful further clinical progress. The following article summarizes the current guidelines for first medical aid at the injury scene, burn stabilization and assessment in the emergency room, and the interdisciplinary approach for further clinical care. The treatment of dermatologic emergencies (acute epidermolytic syndromes) or caustic injuries by chemical agents is similar to the treatment of burn victims in many aspects but must be adapted in selected cases.     

Hand and gender differences in the organization of aiming in 5-year-old children.

The aim of the present study was to analyze the organization of aiming movements in right-handed children aged 5 years, depending on gender and hand used to perform the task. We first tested the hypothesis that aiming movements are predominantly organized in a feed-forward manner before the age of six. Using a direction pre-cueing protocol, we analyzed the effect of gender and hand used to perform the task on reaction time (RT), movement time (MT), spatial accuracy (SA) and acceleration profiles (APs) in children aged 5 years. Differences in RT between the uncued and pre-cued conditions suggest that the direction is actually specified prior to the execution of the movement at the age of five. However, the results also show significant hand and gender effects on MTs, spatial error and APs. Specifically, in girls, MT and kinematics profiles vary as a function of hand and target localization, whereas this is not the case in boys. In addition, SA is lower when aiming with the non-dominant hand in boys, but not in girls. These results suggest that multiple movement strategies are already available to the child at the age of five. Girls appear to be able to change movement strategy as a function of the constraints of the task, resulting in a stability of spatial accuracy (SA). On the contrary, the functional advantage of the right hand on MT and SA generally reported in right-handed males is not present in the boys at the age of five.
