[Lung cancer in a young female patient]. / Nuoren naisen mikrobi- ja astmalääkitykseen reagoimaton yskä ja hengenahdistus.

Lung cancer is the most significant cause of cancer-related deaths in Finland. The diagnosis is still a challenge in outpatient settings. With early diagnosis, patients may receive curable treatment. We describe a young female lung cancer patient with prolonged upper airway infection as a symptom of the disease.

[Traumatic pseudoaneurysm of the superficial temporal artery]. / Sykkivä sarvi otsalla.

Pseudoaneurysms of the superficial temporal artery (STA) are uncommon vascular lesions. Approximately 75% of them result from blunt trauma. Other etiological factors include penetrating wounds, iatrogenic trauma such as hair grafting and neurosurgical procedures. Thorough history and physical examination are often sufficient to make the diagnosis. Imaging studies are recommended for closer morphology and to rule out intracranial vascular communications and other possibilities in the differential diagnosis. We present successful treatment of a traumatic STA pseudoaneurysm with ultrasound-guided percutaneuous thrombin injection.

Delignification and Ionic Liquid Treatment of Wood toward Multifunctional High-Performance Structural Materials.

Wood-based multifunctional materials with excellent mechanical performance are increasingly considered for sustainable advanced applications due to their unique hierarchical structure and inherent reinforcing cellulose phase orientation. Nonetheless, a wider multipurpose utilization of wood materials is so far hampered because of constraints arising from scalable functionalization, efficient processing, facile shaping as well asnatural heterogeneity and durability. This study introduces a multifunctional all-wood material fabrication method relying on delignification, ionic liquid (IL) treatment, and pressure-assisted consolidation of wood. Structure-retaining controlled delignification of wood was performed to enable direct access to the hierarchical cellulose assembly, while preserving the highly aligned and thus beneficial wood structural directionality. As a following step, the obtained biobased scaffold with an increased porosity was infiltrated with an IL and heat-activated to partially dissolve and soften the cellulose fiber surface. Samples washed with water to remove IL exhibited pronounced isotropic flexibility, which upon combined compression and lateral shear allowed the fabrication of various 3D shapes with adjustable fiber architecture. The obtained very compact and totally additive-free all-wood materials were extensively characterized, revealing superior mechanical performance, and gained multifunctionality compared to native wood.

Chemical investigation and quality of urban dew collections with dust precipitates.

The quality and chemical composition of urban dew collections with dust precipitates without pre-cleaning of the collecting surface WSF (white standard foil) were investigated for 16 out of 20 collected samples with collected volumes ranging from 22 to 230 ml. The collection period was from March to July 2015 at an urban area, Jubaiha, which is located in the northern part of the capital city Amman, Jordan. The obtained results indicated the predominance of Ca2+ and SO42- ions (ratio 2.2:1) that originated from Saharan soil dust; where the collected samples were alkaline (mean pH = 7.35) with high mineralization (429.22 mg/L) exceeding the previously reported dew values in Amman-Jordan. A relocation of NaCl and to a less extent Mg2+ from sea to land by Saharan wind is indicated by the percent sea-salt fraction calculations (over 100 and 52, respectively). The collected samples exhibited high total organic carbon (TOC) values ranging from 11.86 to 74.60 mg/L, presence of particulate settled material with turbidity ranging from 20.10 to 520.00 NTU, and presence of undesired elements like boron (mean = 1.48 mg/L) that made it different in properties from other dew water collections at clean surfaces, and exceeding the standard limits for drinking water for these parameters set by Jordanian Drinking Water standards (JS286/2015)/WHO standard. The quality of this water is more close to that for raw or agricultural water but if it is meant to be used as potable source of water, at least sand and activated charcoal filters are needed to purify it.
