Abstract
Endoscope is an innovative method for otologists in middle ear surgery. Many previous studies have confirmed the safety and efficiency of the endoscopic technique, as a reliable therapeutic option with very low complication rates, clearly supporting the use of endoscopy in ear surgery. Auricular suppurative perichondritis secondary to exclusive endoscopic ear surgery for tympanoplasty is an extremely rare type of those without any previously reported cases. In this report, we describe the course of auricular suppurative perichondritis of a 55-year-old woman. The patient was ultimately healed through surgical debridement and postoperative dressing with no evidence of recurrence at two months follow-up. There were no auricle deformity or external auditory canal stenosis with six months following-up.

Perichondritis of the auricle: bacterial findings and clinical evaluation of different antibiotic regimens. Eur Arch Otorhinolaryngol 2019; 276:2199-2203. [PMID: 31079204 DOI: 10.1007/s00405-019-05463-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 05/03/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE Pseudomonas aeruginosa is commonly found in suppurative perichondritis, but the significant pathogens in non-abscess perichondritis are unclarified. We aimed to explore the bacterial findings and evaluate the effectiveness of different antibiotic regimes in the treatment of patients with perichondritis. METHODS All patients treated for perichondritis at the two Ear-Nose-Throat Departments in Central Denmark Region (covering 20% of the Danish population) from January 1990 to October 2018 were included. RESULTS In total, 112 patients with (n = 12) or without (n = 100) abscess were included in the study. Potential pathogens were found in 40 of 55 cultures. P. aeruginosa was recovered in 58% of abscess cases, while Staphylococcus aureus was predominant in non-abscess infections (49%). Eighty-two percent of S. aureus recovered were isolated as heavy or moderate growth. In non-abscess cases, no significant differences in clinical progress (p = 0.65), alteration in antibiotic therapy (p = 0.31), duration of hospitalization (p = 0.65), or frequency of relapse of infection (p = 1.00) or sequelae (p = 0.38) were found between patients treated with antibiotics covering S. aureus vs. P. aeruginosa. CONCLUSIONS Our findings suggest that intravenous antibiotic therapy covering S. aureus is sufficient and appropriate empirical treatment in the majority of patients with non-abscess perichondritis. Antibiotic coverage should be expanded to include P. aeruginosa if the clinical response is disappointing or cultures grow P. aeruginosa. The risks and downsides to this approach seems limited as only a minority of patients suffered (minor) cosmetic sequelae and relapse of infection in our cohort of non-abscess perichondritis patients initially treated with antibiotics not covering P. aeruginosa.

Abstract
In recent years, antimicrobial peptides have received increased interest and are potential substitutes for antibiotics. However, natural antimicrobial peptides are always toxic to mammalian cells and usually exhibit weak antibacterial activity, which restrict their wide application. In this study, a novel antibacterial peptide named PEW300 was designed with three mutations to the parental peptide cecropin A. As predicted by bioinformatic programs, the positive charge of PEW300 increased from + 6 to + 9 compared with cecropin A, and the grand average of hydropathicity increased from - 0.084 to - 0.008. Expression of PEW300 resulted in serious inhibition of Escherichia coli BL21(DE3) cells, indicating designed PEW300 may have stronger antibacterial activity. A simple, fast, and low-cost approach without tedious protein purification steps was selected for the efficient production of PEW300 by fusion with ELK16 and about 7.38 μg/mg wet cell weight PEW300 was eventually obtained. Purified PEW300 exhibited strong antibacterial activity against various Gram-positive and Gram-negative bacteria which was enhanced four- to sevenfold compared with the parental peptide cecropin A. Besides, PEW300 had no hemolytic activity toward mammalian cells even at high concentration (224 ng/μl). PEW300 showed good stability in neutral and alkaline solutions. Moreover, PEW300 was thermally stable even at up to 100 °C and resistant to proteinase K, pepsin, snailase, and trypsin. The incubation with human serum had no effect on the antibacterial activity of PEW300. All these results demonstrated that PEW300 designed in this work may have good potential as a candidate pharmaceutical agent.

Abstract
Following a cluster of serious pseudomonas skin infections linked to a body piercing and tattooing premises, a look-back exercise was carried out to offer clients a screen for blood-borne viruses. Of those attending for screening 72% (581/809) had a piercing procedure in the premises of interest: 94 (16%) were under 16 years of age at the time of screening. The most common site of piercing was ear (34%), followed by nose (27%), nipple (21%) and navel (21%). A small number (<5) tested positive for hepatitis B and C, with no evidence this was linked to the premises. However, 36% (211/581) of clients reported a skin infection associated with their piercing. Using data from client forms, 36% provided a false age. Those aged under 16 years (OR 4.5, 95% CI 2.7-7.7) and those receiving a piercing at an intimate site (OR 2.1, 95% CI 1.3-3.6) were more likely to provide a false age. The findings from this exercise were used to support the drafting of the Public Health (Wales) Bill which proposed better regulation of piercing premises and the need to provide proof of being 18 years of age or over before having a piercing of an intimate site.

Abstract
The frequency of body piercing has increased in France over the past few years, particularly among teenagers. Piercing can be performed at different sites on the body, especially in the cartilage of the ears. We relate two cases of Pseudomonas aeruginosa chondritis. A 10-year retrospective study at the Marseille University Hospital found no additional pediatric cases. These infectious complications can sometimes be necrotizing. It is therefore important to inform the medical staff on the hygiene measures that need to be respected and the patients on the treatment to follow after the piercing as well as the signs to watch for, possibly indicating chondritis. The esthetic consequences depend on early diagnosis.

Abstract
Introduction Outbreaks linked to cosmetic piercing are rare, but can cause significant illness. We report the investigation and management of a point-source outbreak that occurred during a Black Friday promotional event in North West England. Methods Outbreak investigation was led by Public Health England, and included active case finding among individuals pierced at a piercing premises between 25/11/2016 (Black Friday) and 7/12/2016. Detailed epidemiological, environmental (including inspection and sampling), and microbiological investigation was undertaken. Results During the Black Friday event (25/11/2016), 45 people were pierced (13 by a newly-appointed practitioner). Eleven cases were identified (7 microbiologically-confirmed, 2 probable, and 2 possible). All cases had clinical signs of infection around piercing sites, and five required surgical intervention, with varying degrees of post-operative disfigurement. All confirmed and probable cases had a scaffold piercing placed with a guide bar by the newly-appointed practitioner. Pseudomonas aeruginosa, indistinguishable at nine-locus variable-number tandem repeat loci, was isolated from four of the confirmed cases, and from pre- and post-flush samples from five separate water taps (three sinks) in the premises. Water samples taken after remedial plumbing work confirmed elimination of Pseudomonas contamination. Discussion Although high levels of Pseudomonas water contamination and some poor infection control procedures were identified, infection appeared to require additional exposure to an inexperienced practitioner, and the more invasive scaffold piercing. A proactive collaborative approach between piercers and health and environmental officials is required to reduce outbreak risk, particularly when unusually large events are planned

Abstract
OBJECTIVES/HYPOTHESIS The purpose of this systematic review was to critically analyze infectious complications and treatment following transcartilaginous ear piercing. DATA SOURCES MEDLINE Pubmed database. REVIEW METHODS A MEDLINE PubMed database search using free text, including "ear chondritis," "ear perichondritis," "ear cartilage piercing," and "auricle piercing," yielded 483 titles. Based on set inclusion and exclusion criteria, the titles, abstracts, and full text articles were reviewed for inclusion and underwent data extraction. Pooled outcomes are reported. RESULTS A total of 29 articles met inclusion criteria, including 66 patients. The mean age of the patients was 18.7 ± 7.6 years (range: 11-49), 87.5% female. Ear deformity was more likely to occur following postpiercing perichondritis of the scapha 100% versus the helix 43% (P = 0.003). Mean duration of symptoms prior to patients seeking medical attention was 6.1 ± 4.1 days. Greater than 5 days of symptoms prior to seeking treatment was significantly more likely to result in hospitalization. Pseudomonas aeruginosa accounted for 87.2% infections. Of the patients with Pseudomonas, 92.3% were hospitalized versus 75% of the patients infected with Staphylococcus aureus. Initial oral antibiotics prescribed did not target the cultured bacterium in 53.3% of cases; of these, 87.5% were hospitalized. CONCLUSIONS Transcartilaginous postpiercing infection may lead to ear deformity and hospitalization. Patients (customers) and practitioners must be aware of optimal treatment strategies to minimize associated morbidity. Scapha piercing and delay in presentation are associated with poorer outcomes. Pseudomonas is the most common bacterial infection. Initial antibiotic selection must be optimized accordingly.

Abstract
Acute otitis externa, also known as 'swimmer's ear', is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

Abstract
AbstractObjective:This paper reports a series of patients with sporadic pinna perichondritis who presented to a district general hospital over a period of 10 years. The data examined included the causative organism, risk factors and pattern of antibiotic use.Method:A retrospective analysis of diagnosed cases of pinna perichondritis from 2001 to 2012 was performed. A literature review of pinna perichondritis was carried out using Pubmed with the key words ‘pinna perichondritis’, ‘pinna abscess’, ‘pinna infection’ and ‘piercing’.Results:Pinna perichondritis was more likely to result from chondral than lobe piercings. The majority of cases were caused byPseudomonas aeruginosa.Conclusion:Most patients were not prescribed anti-pseudomonal antibiotics on presentation. This may result in persistent infection and long-term cosmetic defects.

Abstract
Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, transmission of bloodborne pathogens (viral hepatitis and human immunodeficiency virus), and distant infections such as infective endocarditis. Presence of foreign bodies, long healing time of piercing wounds, and poor compliance with infection control practices of some practitioners all predispose the recipients to infections. Apart from the endogenous microbial flora of the skin and mucosae, atypical mycobacteria, especially the rapid growers, have emerged as some of the most important pathogens in such settings. Outbreaks of infection are commonly reported. We hereby review the current knowledge of the topic with specific focus on infections associated with tattooing, body piercing, breast augmentation, mesotherapy, liposuction, and tissue filler injections. Greater awareness among consumers and health-care professionals, as well as more stringent regulations by the health authorities, is essential to minimize the health risks arising from these procedures.

Abstract
Ear piercing (EP) is increasing in popularity among teenagers. Techniques for EP should be selected carefully to prevent possible complications. The purpose of this study is to compare the clinical outcomes of EP techniques between CO(2) laser and spring-loaded gun. This is a prospective and comparative clinical trial. Under local anesthesia, EP was performed on left ear with CO(2) laser (20 watt/single mode) and on right ear with spring-loaded gun. With visual analog scale (VAS, 0-10) and questionnaire, post-operative pain and wound healing status were assessed immediately, 1, 2, 4 and 8 weeks after EP procedure. Fourteen subjects (14/17, 82.4%) completed the whole study. Immediately after the procedure, the level of post-operative pain (VAS) was 3.2 for CO(2) laser and 1.5 for spring-loaded gun (p < 0.05). In CO(2) laser group, pain severity decreased to 0.4, 0.1, 0, and 0, while in spring-loaded gun group, the decrease was only to 0.7, 0.6, 0.3 and 0 at 1, 2, 4, and 8 weeks, respectively. Duration of post-operative pain was 3.8 and 17.5 days for CO(2) laser and spring-loaded gun, respectively (p < 0.05). There was no major complication like infection, bleeding or hypertrophic scar. Our study suggests that CO(2) laser is a precise, simple, safe and aseptic technique for EP. It has a lower level and shorter duration of post-operative pain, when compared with spring-loaded gun. Therefore, CO(2) assisted EP is an alternative and feasible technique in our daily clinical practice. The level of evidence: 2b.
