In studies of the relief evolution of smaller landforms, up to several dozen meters in width/diameter, digital elevation models (DEMs) freely accessible in different repositories may be insufficient in terms of resolution. Existing geophysical or photogrammetric equipment is not always available due to costs, conditions and regulations, especially for students or young researchers. An alternative may be the handy-held ground-based Structure from Motion technique. It allows us to obtain free high-resolution DEMs (~0.05 m) using open-source software. The method was tested on kettle holes of the glacial flood origin on Skeiðarársandur (S Iceland). The material was collected in 2022 at two outwash levels of different ages and vegetation cover. The dataset is available in the Zenodo repository; the first part is data processed in point clouds and DEMs, and the second includes original videos in MOV format. The data can be used as a reference to assess changes in the kettle hole relief in subsequent research seasons, as a methodological study for other projects, or for didactic purposes.

Background: Currently, serum PSA is the most commonly used screening tool in clinical practice. However, PSA levels in the range of 4-10 ng/ml are considered the 'grey zone' of prostate cancer screening. Patients within this range need to be further evaluated using additional parameters such as PSA ratio, PSA density, and other indices to determine the necessity of prostate biopsy (PBx).

Unlabelled: Uremic leontiasis ossia (ULO) is a rare manifestation of renal osteodystrophy in) patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH). It occurs due to increased osteoclastic activity secondary to high plasmatic parathyroid hormone (PTH) levels. This leads to bone deformation with thickening and massive enlargement of the cranial vault, resulting in a leonine face appearance.

Histiocytosis are caused by pathogenic myeloid cells, and can be classified as Langerhans cell histiocytosis (LCH) and non-LCH. Erdheim-Chester disease (ECD) is a non-LCH, characterized by multi-organ involvement, typical imaging findings, and confirmatory histological studies. A case with multi-organ involvement and histological confirmation is presented.
