We describe a case of perichondritis by Pseudomona aeruginosa after piercing of the right posterior third of the ear pinna cartilage (high ear piercing) in an otherwise healthy Caucasian adolescent female of 16 years old at a local shop. Based on the tissue sample culture, she was successfully treated with ceftriaxone after a non-respondent first treatment, minimizing the destruction of the ear...

Given a finite family F of convex sets in R, we say that F has the (p, q)r property if for any p convex sets in F there are at least r q-tuples that have non empty intersection. The piercing number of F is the minimum number of points we need to intersect all the sets in F . In this paper we willl find some bounds for the piercing number of families of convex sets with (p, q)r properties.

This paper is discussing the potential consequences that may arise by the implementation of piercing in the oral cavity and is also categorizing the consequences according to their extent and severity. Furthermore, this paper is reviewing some possible oral hygiene methods that can prove to be auxiliary in decreasing the potential complications arising from oral piercing. This literature review...

Perichondritis is a slow evolving infection, located on the ear cartilage. They result from lacerations, blunt trauma, surgeries and other affections. Ear piercing induced pinna perichondritis is a frequent affection among the young population. The most commonly found etiologic agent is Pseudomonas aeruginosa and its inoculation caused by pinna cartilage and pericondrium exposure during or afte...

Piercing invades subcutaneous areas and has a high potential for infectious complications. The number of case reports of endocarditis associated with piercing is increasing. We studied a 25-year-old man with a pierced tongue, who arrived at Memorial Health University Medical Center with fever, chills, rigors, and shortness of breath of 6 days' duration and had an aortic valvuloplasty for correc...

A 43-year old man presented with chest pain and fever. He had inadvertently inhaled a nasal piercing which caused injury to the descending aorta through the left bronchus. The resulting pseu-doaneurysm was treated with endovascular stenting after left carotido-subclavian bypass (Figs 1 and 2). The patient died 2 years later due to drug overdose. Figure 1: CT scan showing the false aneurysm (ast...
