The chemical matricectomy with 88% phenol solution is the gold standard and a wedge resection is indicated for more advanced stages. The aesthetic reconstruction has the advantages of the incisional procedure without eponychium incisions and an effectiveness similar to the chemical matricectomy with phenol. Objective: To compare the recurrence and the healing time between the chemical matricectomy with phenol and the aesthetic reconstruction. Methods: A comparative, prospective, parallel, randomized, and one-blinded clinical trial was registered with the European Clinical Trials Database (EudraCT) with identification number 2019-001294-80. Thrity-four patients (56 feet) with 112 onychocryptosis were randomized in two groups. Thirty-six were treated with chemical matricectomy with phenol and 76 with aesthetic reconstruction. Each patient was blind to the surgical procedure assigned by the investigator. The primary outcome measurements were healing time and recurrence. The secondary outcome measurements were post-surgical bleeding, pain, inflammation, and infection rate.

  • Partial Nail Avulsion and Chemical Matricectomy: Ingrown Toenails
    Partial nail avulsion and chemical matricectomy: Ingrown toenails Intervention Removal (avulsion) of an ingrowing section of toenail and application of a caustic chemical to destroy the nail matrix (matricectomy). Indication Partial nail avulsion and chemical matricectomy relieve symptoms and prevent regrowth of the nail edge or recurrence of the ingrowing toenail. Possible causes of ingrowing toenails include improper Ingrowing toenails are a common problem and occur when the edge of the nail grows trimming of the nail, tearing nail into flesh at the side of the nail, causing a painful injury. The punctured skin can become off, overly curved nail, certain inflamed and infected. Ingrown toenails can be classified into three stages (see Figure 1): activities (eg running) and • mild (or Stage I) wearing constricting footwear. – oedema, erythema and pain • moderate (or Stage II) – inflammation and inflection with or without purulent discharge, in addition to the symptoms of Stage I • severe (or Stage III) – chronic inflammation, epithelialised hypertrophic granulation tissue. Figure 1. Three stages of ingrown toenails Source: Eekhof JA, Van Wijk B, Knuistingh Neven A, van der Wouden JC. Interventions for ingrowing toenails. The Cochrane Database of Systematic Reviews 2012;4:CD001541. Surgical interventions are commonly performed for patients in Stages II and III, and are more effective than non-surgical interventions in preventing the recurrence of an ingrowing toenail. The addition of chemical cauterisation (most commonly with phenol) at Stages II and III, may be more effective in preventing recurrence and regrowth of the ingrowing toenail than surgery alone. Contraindications Diminished vascular supply to the digit is a relative contraindication to nail surgery.

  • Hatchery Disinfection Policy and Procedures
    MAINE DEPARTMENT OF INLAND FISHERIES & WILDLIFE Chapter 11 Disinfection Policy & Procedures Editors: David C. Rayner, Fish Culture Supervisor, Governor Hill State Fish Hatchery, Augusta, Maine (19XX- Present) & G. Russell Danner MS, DVM, Fish Pathologist, Fish Health Laboratory, Augusta, Maine (1998 – Present) Date: September 24, 1999. “Or if a person touches anything ceremonially unclean-whether the carcasses of unclean wild animals or of unclean livestock or of unclean creatures that move along the ground-even though he is unaware of it, he has become unclean and is guilty” Lev. 5:2 Several factors should be included in an evaluation of a disinfectant. A prerequisite for a disinfectant is its effectiveness against the expected spectrum of pathogens (Table 11- 1, 11-2, and 11-3). A general guideline for effective killing of pathogens by a disinfectant is a 5-log killing of bacteria and a 4-log killing of viruses. In addition to the activity of the disinfectant, its compatibility with devices should be reviewed in detail; this should include a review of data on devices that have been immersed for longer than recommended times. Instruments can be forgotten after immersion, and this mistake should not necessarily result in irreparable damage to the device. Other issues are toxicity, odor, compatibility with other compounds, and residual activity. Various and numerous organisms can cause diseases in fish. Viruses, bacteria, fungi, protozoan and many invertebrate animals are included in this list. No single disinfectant destroys them all. It is up to the applicant to decide what is the pathogen of most concern, and how it is to be reduced or eliminated.

  • Components of a Vaccine
    Components of a vaccine Vaccines include a variety of ingredients including antigens, stabilizers, adjuvants, antibiotics, and preservatives. They may also contain residual by-products from the production process. Knowing precisely what is in each vaccine can be helpful when investigating adverse events following immunization (AEFIs) and for choosing alternative products for those who have allergies or have had an adverse event known or suspected to be related to a vaccine component. Antigens Antigens are the components derived from the structure of disease-causing organisms, which are recognized as 'foreign' by the immune system and trigger a protective immune response to the vaccine. You have already learned about antigens. Click here if you want to review the chapter on antigens. Stabilizers Stabilizers are used to help the vaccine maintain its effectiveness during storage. Vaccine stability is essential, particularly where the cold chain is unreliable. Instability can cause loss of antigenicity and decreased infectivity of LAV. Factors affecting stability are temperature and acidity or alkalinity of the vaccine (pH). Bacterial vaccines can become unstable due to hydrolysis and aggregation of protein and carbohydrate molecules. Stabilizing agents include MgCl2 (for OPV), MgSO4 (for measles), lactose- sorbitol and sorbitol-gelatine. Adjuvants Adjuvants are added to vaccines to stimulate the production of antibodies against the vaccine to make it more effective. Aluminium salts example Adjuvants have been used for decades to improve the immune response to vaccine antigens, most often in inactivated (killed) vaccines. In conventional vaccines, adding adjuvants into vaccine formulations is aimed at enhancing, accelerating and prolonging the specific immune response to vaccine antigens.

ROSS From the Department of Bacteriology, University of Edinburgh SYNOPSIS Qualitative and quantitative tests have been carried out to assess the value of Cidexl, a glutaraldehyde solution, as a disinfectant. Most of the tests were qualitative and were carried out in conditions as closely resembling those found in hospital practice as possible. Recently used anaesthetic equipment, catheters, and a cysto- scope, which had been artificially contaminated with suspensions of Staph. aureus, Ps. pyocyanea, and Esch. coli, were used in the tests. The results show Cidex to be a useful disinfectant with a valuable potential in disinfecting hospital articles which, due to their perishable nature or the fragility of component parts, cannot be treated by physical means.

  • The Use of Povidone Iodine Nasal Spray and Mouthwash During the Current COVID-19 Pandemic May Protect Healthcare Workers and Reduce Cross Infection
    March 27, 2020 The use of Povidone Iodine nasal spray and mouthwash during the current COVID-19 pandemic may protect healthcare workers and reduce cross infection. J Kirk-Bayley MRCP FRCA EDIC FFICM, Consultant Intensivist & Anaesthetist, Royal Surrey County Hospital S Challacombe, PhD, FRCPath, FDSRCS, FMedSci, DSc(h.c), FKC, Martin Rushton Professor of Oral Medicine, KCL VS Sunkaraneni LLM FRCS(2019), Consultant Rhinologist, Royal Surrey County Hospital J Combes FDS FRCS (OMFS), Lt Col RAMC, Consultant Advisor (ARMY) in OMFS, Defence Medical Services Abstract In late 2019 a novel coronavirus, SARS-CoV-2 causing Coronavirus disease 2019 (COVID-19) appeared in Wuhan China, and on 11th March 2020 the World Health Organisation declared it to have developed pandemic status. Povidone-iodine (PVP-I) has a better anti-viral activity than other antiseptics, and has already been proven to be an effective virucide in vitro against severe acute respiratory syndrome and Middle East respiratory syndrome coronaviruses (SARS-CoV and MERS- CoV). Povidone iodine has been shown to be a safe therapy when inhaled nasally or gargled. We propose that a protocolised nasal inhalation and oropharyngeal wash of PVP-I should be used in the current COVID-19 pandemic to limit the spread of SARS-CoV-2 from patients to healthcare workers (and vice versa) and thus reduce the incidence of COVID-19. There should be regular use in patients with COVID-19 to limit upper respiratory SARS-CoV-2 contamination, but also use by healthcare workers prior to treating COVID 19 patients or performing procedures in and around the mouth/ nose during the pandemic, regardless of the COVID 19 status of the patient.

    toxics Article Exposure to Triclosan and Bisphenol Analogues B, F, P, S and Z in Repeated Duplicate-Diet Solid Food Samples of Adults Marsha K. Morgan 1,* and Matthew S. Clifton 2,* 1 United States Environmental Protection Agency’s Center for Public Health and Environmental Assessment, Research Triangle Park, NC 27711, USA 2 United States Environmental Protection Agency’s Center for Environmental Measurement and Modeling, Research Triangle Park, NC 27711, USA * Correspondence: [email protected] (M.K.M.); [email protected] (M.S.C.) Abstract: Triclosan (TCS) and bisphenol analogues are used in a variety of consumer goods. Few data exist on the temporal exposures of adults to these phenolic compounds in their everyday diets. The objectives were to determine the levels of TCS and five bisphenol analogues (BPB, BPF, BPP, BPS, and BPZ) in duplicate-diet solid food (DDSF) samples of adults and to estimate maximum dietary exposures and intake doses per phenol. Fifty adults collected 776 DDSF samples over a six-week monitoring period in North Carolina in 2009–2011. The levels of the target phenols were concurrently quantified in the DDSF samples using gas chromatography/mass spectrometry. TCS (59%), BPS (32%), and BPZ (28%) were most often detected in the samples. BPB, BPF, and BPP were all detected in <16% of the samples. In addition, 82% of the total samples contained at least one target phenol. The highest measured concentration of 394 ng/g occurred for TCS in the food samples. The adults’ maximum 24-h dietary intake doses per phenol ranged from 17.5 ng/kg/day (BPB) to Citation: Morgan, M.K.; Clifton, M.S.

    Phenol Product Stewardship Summary December 2012 C6H5OH Chemical Name: Phenol Chemical Category (if applicable): Organic Acid Synonyms: Carbolic acid; Phenylic acid; Hydroxybenzene; Monohydroxybenzene; Oxybenzene; Benzenol; Benzophenol; Monophenol; Phenyl hydrate; and Phenylic alcohol CAS Number: 108-95-2 CAS Name: Phenol EC (EINECS) Number: 203-632-7 Other identifier (Please specify): GPS0075 • Phenol is an organic chemical used to produce a wide variety of chemical intermediates. The primary chemical intermediates include phenolic resins, bisphenol A, caprolactam, alkyl phenols and adipic acid. Phenol is also used in numerous small volume applications such as plasticizers, herbicides, wood preservatives, pharmaceuticals and dyes. • Workplace exposures to phenol during its manufacture and use are expected to be minimal because exposures are controlled with process enclosures, local exhaust ventilation, and personal protective equipment. Good manufacturing practices and industrial hygiene practices are also implemented to prevent or reduce exposure to phenol. Worksite safety programs also follow recommended exposure guidelines. Please see the Safety Data Sheet (SDS) for additional information. • Phenol, available in solid or liquid form, is colorless to light pink and has a sweet aromatic odor. It is stable under normal conditions of storage and use. The liquid and vapor are combustible. Phenol is incompatible with strong oxidizing agents, calcium hypochlorite, halogens, halogenated compounds, aluminum chloride, and nitrobenzene. Hot phenol can attack aluminum, lead, magnesium and zinc. It can react exothermally with peroxymonosulfuric acid, sodium nitrate, 1,3-butadiene and boron trifluoride diethyl ether. When phenol is heated to decomposition (ca. 715 °C), decomposition products include carbon monoxide and carbon dioxide. • Phenol can be harmful or fatal if swallowed.

  • Comparative Study of Bactericidal Activities of Six Different Disinfectants
    Nagoya J. Mod. Sci. 47. 101 ~ 112. 1985 COMPARATIVE STUDY OF BACTERICIDAL ACTIVITIES OF SIX DIFFERENT DISINFECTANTS YOSHIMICHI NAMBA*, ASAKATSU SUZUKI*, NOBORU TAKESHIMA** and NOBUO KATO*** * Department of Surgical Center, Nagoya Universi/y Hospital, and ** Deparlment of Anes/hesiology and *** Depar/ment of BaCieriology, Nagoya Universi/y School of Medicine Nagoya 466, Japan ABSTRACT Bactericidal activities of six commonly used disinfectants against scven different species of clinically isolatcd hacteria, mainly glucose-nonfermentative Gram-negative hacilli, were compared. In terms of mean values of the minimum hactericidal concentration (M BC), henzethonium chloride showed the highest efficacy, followed in order hy chlorhexidine gluconate, alkyldiaminoethylglycine hydrochloride, glutaraldehyde, povidone-iodine, and phenol. However, mean MBCs of henzethonium chloride, alkyldiaminoethylglycine hydrochloride and chlorhexidine gluconate against individual species covered a far wider range from species to species compared with those of the other three disinfectants. In addition, hactericidal activities of the ahove-mentioned three disinfectants against Pseudomonas cepacia and Achrolllohaetcr xrlosoxidans ranged more widely from strain to strain than against other species. When the minimum concentrations of individual disinfectants recommended for hospital use hy the manufacturers were used, chlorhexidine gluconate (0.02%), alkyldiaminoethylglycine hydrochloride (0.1%), henzethonium chloride (0.1%) and povidone-iodine (0.75%) were not hactericidal to definite numhers of hacterial strains tested. Among them, chlorhexidine gluconate at the concentration recommended was ineffective against many strains of all hacterial species tested, especially against strains of glucose-nonfermentative Gram-negative hacilli except for PseW/O/llOllaS aerugillosa.
