Validation of the Polish versions of the Lower Limb Task Questionnaire, Lower Limb Functional Index, and Lower Limb Functional Index-10.

Background: Physicians who treat patients with lower limb diseases should pay attention not only to the patients' clinical condition but also to their individual needs and expectations. For this purpose, many different questionnaires can be employed. This study aimed to validate the Lower Limb Task Questionnaire (LLTQ), Lower Limb Functional Index (LLFI), and Lower Limb Functional Index-10 (LLFI-10) for their use in Polish conditions and to perform a mutual comparison and analysis of differences in subjective assessments by patients who undergo hip or knee arthroplasty.

Influence of Metal Oxide Particles on Bandgap of 1D Photocatalysts Based on SrTiO/PAN Fibers.

This paper deals with the study of the optical properties of one-dimensional SrTiO/PAN-based photocatalysts with the addition of metal oxide particles and the determination of their bandgaps. One-dimensional photocatalysts were obtained by the electrospinning method. Particles of metals such as iron, chromium, and copper were used as additives that are capable of improving the fibers' photocatalytic properties based on SrTiO/PAN.

Intra- and postoperative adverse events in awake craniotomy for intrinsic supratentorial brain tumors.

Objective: To determine the frequency and consequences of intra- and postoperative adverse events in awake craniotomy for intrinsic supratentorial brain tumors. Despite the growing prevalence of awake craniotomy intra- and postoperative, adverse events related to this surgery are poorly discussed.

Methods: We studied 25 patients undergoing awake craniotomy with maximum safe resection of intrinsic supratentorial brain tumors in the awake-asleep-awake protocol.

Iatrogenic Common Iliac Vessel Injury During Routine Degenerative Lumbar Spine Surgery: Report of 2 Cases and Review of Literature.

Background: Injury of the iliac vessels is a rare complication of lumbar spine surgery with potentially life-threatening consequences. We present 2 cases of iliac vessel injury that were treated with minimally invasive techniques.

Case Description: The first case was a laceration of the common iliac artery during a simple L4-L5 discectomy in which the injured artery was secured by stent implantation.
