Foreign body ingestion is a common condition in clinical practice, thankfully most of the cases do not require any surgery as most foreign bodies can pass through the bowel without injuring it. Treatment depends on the size and kind of foreign bodies. When complications arise, patients may require urgent medical attention. Self-harm by sharp foreign body ingestion is a rare event that must always be promptly treated and should always be prevented. Psychiatric patients and inmates are the most affected population. A high index of suspicion is required to treat this rare condition, which may be preventable if there is adequate mental and medical therapy along with close monitoring and family support. We present the case of a 31-year-old psychiatric patient. After prompt treatment, two razor blades were surgically removed from her intestines. She fully recovered and is doing well on follow-up controls.

Transmission matrix measurements of multimode fibers are now routinely performed in numerous laboratories, enabling control of the electric field at the distal end of the fiber and paving the way for the potential application to ultrathin medical endoscopes with high resolution. The same concepts are applicable to other areas, such as space division multiplexing, targeted power delivery, fiber laser performance, and the general study of the mode coupling properties of the fiber. However, the process of building an experimental setup and developing the supporting code to measure the fiber's transmission matrix remains challenging and time consuming, with full details on experimental design, data collection, and supporting algorithms spread over multiple papers or lacking in detail.

Barbershops are important venues for men to get their hair and beards done and hence, play an important role in men's social life. But barbershops can also be a source of infections. The barber's profession brings the barber into direct contact with customers who may carry pathogens, and contaminated instruments or skin-to-skin contacts might transmit infectious agents.

Before humans and allegedly any animal group, spiders developed "functionally graded toothed blades" that cut one of the toughest biological materials: silk. Here, this work reveals the importance of micro-structured serrations in spiders' fangs that allow these animals to cut silk and artificial high-performance fibers, such as carbon or Kevlar. The importance of serrations revolves around the stress concentration at the interface between the fang and the fibers, resulting in a cutting efficiency superior to that of a razor blade.

Background: Nerve transfer procedures are performed in patients with proximal nerve injuries to optimize their potential for functional recovery. The study aimed to determine the preferred surgical technique and tool used by peripheral nerve surgeons to transect nerves in nerve transfers.
Methods: All current members of the American Society of Peripheral Nerve were invited to complete a cross-sectional 10-question survey.

Background: The use of full-thickness and split-thickness skin grafts (FTSG/STSG) among dermatologists has not been well characterized.
Objectives: To characterize the utilization of graft techniques, fixation methods and training needs pertaining to graft use among an international cohort of dermatologists.
Methods: An online questionnaire was developed iteratively, and subsequently distributed between July and August 2022 to dermatologists from the UK, European countries and New Zealand (NZ).
