Facial shields are used when practising contact sports, high speed sports, sports using hard balls, sticks or bats, sports using protective shields or covers, and sports using hard boardings around the sports ground. Examples of facial shields are commercially available, per branch of sport standardised helmets. Fabricating individual protective shields is primarily restricted to mouth guards. In individual cases a more extensive facial shield is demanded, for instance in case of a surgically stabilised facial bone fracture. In order to be able to fabricate an extensive individual facial shield, an accurate to the nearest model of the anterior part of the head is required. An accurate model can be provided by making an impression of the face, which is poured in dental stone. Another method is producing a stereolithographic model using computertomography or magnetic resonance imaging. On the accurate model the facial shield can be designed and fabricated from a strictly safe material, such as polyvinylchloride or polycarbonate.

Erythema multiforme major (EMM) is an acute, immune-mediated mucocutaneous disease that rarely affects the genital mucosal surfaces. This study describes a 39-year-old male with this rare disease and unusual presentation. The patient presented to an emergency department with oral lesions, drainage from both eyes, injected sclera, and characteristic targetoid lesions on the face, upper extremities, torso, and plantar surfaces of the feet.

Background: The consequence of non-compliance with patient radiation safety standards increases unnecessary radiation exposure with high chances of harmful biological effects. Radiographers are trained to prevent these harmful effects by enforcing radiation protection, which is achieved through proper techniques, equipment, shielding materials and beam collimation.
Aim: The study aimed to explore compliance with radiation protection by radiographers in Eswatini public health facilities (PHFs).

Superficial lesions of the face are often treated with an electron beam and surface collimation utilizing a conformal lead shield with an opening around the region of treatment (ROT). To fabricate the lead shield, an imprint of the patient face is needed. Historically, this was achieved using a laborious and time-consuming process that involved a gypsum imprinted model (GIM) of the patient topography.
