BACKGROUND The popularity of high ear piercing has led to an increased incidence of perichondritis. Damage to the relatively avascular cartilage will make the ear prone to infection. The literature suggests that a piercing gun, mainly used by jewellers to pierce the lobule, may give excessive cartilaginous damage. Therefore some authors favour the piercing needle, as used in piercing studios. B...

AIM The aims of this review of the literature are to offer further insights into possible problems related to tongue piercing and present three case reports showing undesired effects of tongue piercing. BACKGROUND From a dental perspective, oral piercings and especially tongue piercings are not a harmless fashion trend since they can be associated with local and systemic risks and complicatio...

Introduction: Lupus vulgaris is the most common form of cutaneous tuberculosis caused by contiguous spread from an underlying infective focus or lymphatic or hematogenous spread. It can also develop at the site of direct inoculation (e.g., tattooing and ear piercing) or Bacillus Calmette-Guerin vaccination. The solitary involvement of the pinna is rare and may face clinicians with a diagn...

Several authors described experiments aimed particularly at determination of demandingness of piercing processes, namely with respect to piercing mandrels or their stress load, similarly as e.g. at technology of piercing of extremely high blanks Skripalenko et al. 1 or piercing of continuously cast ingots from alloyed steel 2 . Komori 3 dealt with mathematical simulation of piercing according t...

Abrasive waterjet cutting (AWJ) is a highly efficient method for cutting almost any type of material. When holes shall be cut the waterjet first needs to pierce the material.This paper presents a vast experimental analysis of piercing parameters effect on piercing time. Results from experimentation on feed rates, work piece thicknesses, abrasive flow rates, standoff distances and water pressure...

A comprehensive review of oral and perioral piercing is presented. This contemporary phenomenon has many implications for the piercee and for the oral healthcare professional. Oral and perioral piercing, which have become prevalent recently, both have historical antecedents. The implications of piercing are described in detail including sites at the tongue, lips, cheeks, frenum, and uvula. Comp...

This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...

The factorization property of graviton scattering amplitudes is reviewed and shown to be valid only if the “natural” value of the gyromagnetic ratio gS = 2 is employed—independent of spin.

BACKGROUND Auricular or high helical ear piercing is an increasingly widespread fashion trend that is associated with an increased risk of potentially serious post-piercing complications such as auricular perichondritis. CASE REPORT An 11-year-old girl developed severe auricular perichondritis following piercing of the upper helical cartilage of her ear at a hairdressing salon. Four days post...

This review compares the mouthparts and their modes of operation in blood-feeding Arthropoda which have medical relevance to humans. All possess piercing blood-sucking proboscides which exhibit thin stylet-shaped structures to puncture the host's skin. The tips of the piercing structures are serrated to provide anchorage. Usually, the piercing organs are enveloped by a soft sheath-like part whi...
