The mouth can be an entry point as well as a site for bacterial and viral infections that affect general health status medications for ocd generic dilantin 100mg fast delivery. Oral conditions may not only reflect general health medications in spanish buy generic dilantin canada, but may adversely affect other chronic conditions keratin intensive treatment buy generic dilantin 100 mg on-line. Risk and Protective Factors for Oral Disease Tobacco Use the devastating effects of tobacco use on health and well-being are firmly established treatment leukemia dilantin 100mg without a prescription. Annually medicine yeast infection cheap dilantin on line, nearly one-half million Americans die prematurely from smoking medicine rash discount 100 mg dilantin with amex, while estimated costs of smoking and tobacco exposure are approaching $300 billion per year. Nationally, direct medical costs related to tobacco use and exposure are at least $130 billion per year and productivity losses lead to more than $150 billion in indirect costs. Although the smoking prevalence of high school students has decreased since 2000, the trend of illegal sale of tobacco to minors has not gone down since 2009. Yet disparities remain: African-Americans and American Indians/Alaska natives have the highest smoking prevalence of all racial/ethnic groups in the state, at 21 percent and 29 percent, respectively (Table 3). Annually, more than 35,000 people in California die prematurely from a tobacco-related disease [67] 37 | Page. Public Health Service’s tobacco use and dependence clinical practice guidelines recommend that all health care providers, including dental providers, promote tobacco cessation to all patients and incorporate the guidelines into clinical practice. For children and adolescents, counseling is recommended for adolescents who smoke, because it has been shown to be effective in treating adolescent smokers. Further, counseling is also recommended and shown to be effective in a pediatric setting of parents who smoke. This benefit includes the provision of anticipatory guidance and risk reduction counseling regarding tobacco use. Dental patients may be particularly receptive to health messages at periodic check-up visits, and the oral effects of tobacco use provide visible evidence and a strong motivation for tobacco users to quit. Dentists and dental hygienists can be effective in screening for, and treating, tobacco use and dependence. Results from a nationally representative survey in the United States in 2010–2011 indicated that more than 90 percent of dental providers reported that they routinely asked patients about tobacco use, 76 percent counseled their patients about tobacco use, and 45 percent routinely offered cessation assistance in the form of counseling referrals and cessation prescriptions.

In the United States, community water fluoridation has been the basis for the primary prevention of dental caries for more than 65 years and has been recognized as one of ten great achievements in public health in the 20th century. Water fluoridation is equally effective in preventing dental caries among different socioeconomic, age, racial, and ethnic groups. Water fluoridation helps lower the overall cost of dental care and prevent tooth loss. Although more people are served by fluoridated water in California than in any other state, California ranks 34th in the proportion of the overall population served by community water fluoridation. The 1993-1994 survey led to the 1995 California fluoridation law (Assembly Bill 733) and subsequent plans to expand the number of community water systems with fluoridation in California. Public health measures can include fluoride mouth rinse or tablet programs, which typically are conducted in schools. Individual measures include professionally applied topical fluoride gels or varnish for persons at high risk of dental caries. Preventive Services Task Force guidelines for oral health recommend that primary care clinicians prescribe oral fluoride supplementation starting at age 6 months for children whose water supply is deficient in fluoride, and apply fluoride varnish to the primary teeth of all infants and children starting at the age of primary tooth eruption. Dental Sealants Since the early 1970s, the incidence of childhood dental caries on smooth tooth surfaces (those without pits and fissures) has declined markedly because of widespread exposure to fluorides. Most decay among school-age children now occurs on tooth surfaces with pits and fissures, particularly the molar teeth. Pit-and-fissure dental sealants—plastic coatings bonded to susceptible tooth surfaces— have been approved for use for many years and recommended by professional health/dental associations and public health agencies. The Community Preventive Services Task Force recommends school-based sealant delivery programs based on strong evidence of effectiveness in preventing tooth decay among children. Therefore, young 40 | Page teenagers need to receive dental sealants shortly after the eruption of their second permanent molars, usually between aged 11 and 14. Children received dental sealants, fluoride supplements (such as fluoride varnish, mouth rinse, and tablets), oral health education, toothbrush/flossing instruction, and, in some cases, oral health screenings. Oral Health Education Oral health education informs, motivates, and helps people adopt and maintain beneficial health practices and lifestyles; causes policy makers to create policy and environmental changes to improve oral health; and leads to professional training and research to the same end. Early Detection of Oral Cancer Survival rates from oral cancers vary widely, depending on the stage of disease at diagnosis (Figure 18). In California, oral cancer diagnosed at a localized stage has the highest five-year survival rate—85. Although early detection greatly improves survival rates, the evidence is insufficient to assess the balance of benefits and harms of screening for oral cancer in asymptomatic adults. Five-Year Relative Survival for Oral and Pharyngeal Cancer in California by Stage at Diagnosis, 2002-2011 90 85.

This is because the numbers in the table are age-specific proportions and not actual case counts. In other words, the average of sums (case counts) is not the same as the average of the proportions. Dental Services Dental Visits Although appropriate home oral care and population-based prevention are essential, professional dental care is also necessary to maintain optimal oral health. Regular dental visits provide an opportunity for early diagnosis, prevention, and treatment of oral diseases and conditions for people of all ages, and for the assessment of self-care practices. Adults who do not receive regular professional dental care can develop oral diseases that eventually require complex treatment and may lead to tooth loss and health problems. People who have lost all their natural teeth are less likely to seek periodic dental care than those with teeth, which, in turn, decreases the likelihood of early detection of oral cancer or soft tissue lesions from medications, medical conditions, tobacco use, and/or poorly fitting or poorly maintained dentures. In California, racial and ethnic minorities, people with less than a high school education, and those with annual incomes under $25,000 are least likely to have visited a dentist or dental clinic within the prior 12 months (Table 5). Proportion of Persons Aged 18+ Years Who Visited a Dentist or Dental Clinic in the Previous 12 Months in 2008 Dental Visit in Previous Year, 2008 United States California (%) (%) Healthy People 2020 Target: 49. Percent of Children and Teens in California Who Have Had a Dental Visit in the Last Year by Percent of Federal Poverty Level, 2011–2012 100 96. In 2012, emergency departments in California had approximately 113,000 visits for preventable dental conditions. In 2009, the California Healthcare Foundation found that the average cost of a preventive dental visit ranged from $41 to $60, whereas the median cost of emergency treatment is nearly three times greater, at $172. If treatment for the dental emergency requires hospitalization, the median cost increases dramatically to over $5,000. The age-adjusted rates shown in Figure 20a allow for comparison between counties by calculating the number of emergency room visits per 100,000 people. Figure 20b shows the absolute number of emergency department dental visits by county. When considering the number of dental visits alone, Figure 20b seems to show a higher number of dental visits concentrated in the southern counties. This is because the population in the southern counties is higher than the population in northern counties. However, when standardizing the population in each county and calculating the number of visits per 100,000 people, Figure 20a shows a more accurate reflection of the rate of emergency department dental visits. Thus, of California’s 58 counties, Del Norte, Modoc, Siskiyou, Lake, and Shasta Counties have the highest age-adjusted rates of preventable emergency department dental visits. However, by sheer volume, San Diego, Riverside, Sacramento, San Bernardino, and Los Angeles Counties have the greatest number of emergency department visits for preventable dental conditions. Routine and timely preventive care would reduce the need for emergency department visits for dental conditions (Figure 21). Medi-Cal and Denti-Cal Medicaid (known as Medi-Cal in California) is the primary source of health care for approximately 13. This program is jointly funded by federal and state governments to assist states in providing medical, dental, and long-term care assistance to people who meet certain eligibility and medical necessity criteria. In 2011, the California Healthcare Foundation reported that Medi-Cal expenditures for dental services accounted for approximately 1 percent of the $41. A referral to a dental provider is 47 | Page required for every child in accordance with the periodicity schedule set by the American Academy of Pediatric Dentistry. Although most states provide at least emergency dental services for adults, less than half provide comprehensive dental care. Except for pregnant women, there are no federally mandated minimum requirements for adult dental services. As of May 1, 2014, the Medi-Cal Dental Program (Denti-Cal) restored many adult dental services. These restored benefits include: exams and x-rays, cleanings (Prophylaxis), fluoride treatments, fillings, root canals in front teeth, prefabricated Crowns (stainless steel or tooth colored), full dentures, and other medically necessary dental services. Cosmetic procedures, experimental procedures, and orthodontic services for adults are not covered benefits. The Denti-Cal provider manual governs which procedures are covered benefits and the frequency at which they are allowable. A health assessment consists of a health history, physical examination, developmental assessment, nutritional assessment, dental assessment, vision and hearing tests, a tuberculin test, laboratory tests, immunizations, health education/anticipatory guidance, and referral for any needed diagnosis and treatment. In 2016 in the individual market, twelve health insurance plans sold through Covered California include pediatric dental benefits for members under age 19; tax subsidies are available to qualified families. Covered California will also offer six stand-alone family dental insurance plans that will provide comprehensive dental benefits for children and adults. Adults can choose to enroll in one of these dental insurance plans without enrolling all family members. Of those enrolled, 1,222,320 (88 percent) were eligible to receive federal subsidies to mitigate costs. These clinics serve populations in areas where economic, geographic, or cultural barriers exist, and are a key component of the medical safety net. The Migrant Health Program is distributed throughout California and delivers health services to more than 650,000 migrant and seasonal farm workers. Many migrant health centers provide dental services in addition to primary care services. Innovative Models of Care Virtual Dental Home the traditional dental care system has primarily delivered dental services in brick-and-mortar offices and clinics. Most data about dental services is based on billing claims or other information from this fixed-facility delivery mechanism. It uses the latest telehealth technology to link practitioners in the community with dentists at remote office sites. Data collection and reporting systems will need to capture data about this and other innovative 50 | Page community-based dental care systems to demonstrate increased access to care, improved outcomes, and costs saved. The grant included the development of a blueprint for a value-based purchasing project for Medi-Cal/Denti-Cal. The project plan included quality of care and outcome measures, a high-level project operations plan to implement strategies, and a description of policy, procedure, and strategy changes. Access to Dental Services A critical component of quality care is access to services. Health policies intended to expand access to care, improve quality of care, or constrain costs must take into consideration the supply, geographic distribution, and utilization of dental providers. Less than 40 percent provide dental services in the other 53 counties in California (11 percent of dentists live out of state). The 5 counties with the most dentists were Los Angeles, Orange, San Diego, Santa Clara, and Alameda—a total of 18,659 dentists. In comparison, the five counties with the fewest dentists—Sierra, Mono, Colusa, Trinity, and Modoc—had a combined total of 17 dentists (Figure 22). Current Supply of Dentists by County of Record, 2013 Data Source: Department of Consumer Affairs, Dental Board of California Public Master File, June 2013. For purposes of this Fact Sheet, currently licensed dentists are defined as “renewed and current”. Revised 10/30/2013 52 | Page the distribution of Registered Dental Hygienists in California showed a similar trend. In the same 2013 survey, over 50 percent of Registered Dental Hygienists reside in 8 of the state’s 58 counties; less than 50 percent provide dental services in the remaining 50 counties. In addition, the majority (56 percent) of Registered Dental Hygienists work part-time [Figure 23). Dental Providers One cause of oral health disparities is a lack of access to dental services, in particular among racial/ethnic populations. Nearly 50 percent of dentists in California are Caucasian/White/European or Middle Eastern. Dentists who identify as African-American/Black/African, Latino/Hispanic, Indian/Native-American/Alaska-native or native-Hawaiian/Pacific-Islander make up less than 10 percent of the workforce. The predominant language spoken by dentists is English, and Spanish is second (Figure 25). Distribution of Dentists in California by Race/Ethnicity, 2013 African American/Black/ African Indian/Native 1% American/Alaskan Latino/Hispanic Native 3% 0. Of the 19,407 Registered Dental Hygienists surveyed, over 12,000 are Caucasian/White/European or Middle Eastern, and the predominant language spoken is English, followed by Spanish (Figure 26). Of the dentists surveyed, the majority were age 55 and older; dentists under the age of 34 made up the smallest cohort. California could experience a shortage of dentists if there is not an adequate supply of younger dentists to replace them. The median age of Registered Dental Hygienists was 48, and the median number of years of licensure was 16. From 2006 through 2012, these schools awarded 4,770 dental degrees, with an average of 680 graduates per year. In 2013, there were an average of 580 job openings at any time for both new and replacement dentists in California.

The structure provides some stability by providing some depth to the “socket” side of the joint medicine 54 092 order dilantin online. Tears have been implicated as internal derangements that may cause restriction treatment for 6mm kidney stone discount dilantin 100 mg online, clicking symptoms torn meniscus buy discount dilantin on-line, and sometimes painful limitation of arm movement treatment xyy cheap dilantin generic. Tears may also occur with sudden or excessive biceps contraction on the upper part of the labrum where the biceps tendon inserts symptoms sleep apnea buy dilantin visa. Rotator cuff tendonosis/tear: the rotator cuff consists of the supraspinatus medications purchase generic dilantin on line, infraspinatus, subscapularis, and teres minor muscles which originate on the scapula and whose tendons insert on the humerus. When damaged by sudden trauma, overuse, or overexertion, fibers of the tendon become sprained and inflamed. Partial supraspinatus tears are the most common and may occur on the bursal side or the articular side of the tendon. Differential Diagnosis and Management for the Chiropractor – Protocols and Algorithms. From behind  Painful Arc test – Active abduction from hand at side to hand over head is pain patient stabilize scapula with one hand and humeral head with other. Pain in midrange by poster to anterior pressure toward glenoid to test anterior stability; pull backward is positive. Provide resistance against further shoulder flexion and evaluate for  Neer’s test – assesses for possible rotator cuff impingement. If pain was present with the thumb down but relieved with the thumb up, it is considered a scapula (place your hand firmly upon the acromion, or hold the inferior angle of positive test, suspicious for a labral tear. Stabilize the of the humerous with a posterior force to see if the pain and or sense of apprehension is relieved. Rotator Cuff Tears  Yergason’ s test – Flex elbow to 90°, shake hands with patient and provide  Abduction test – Active abduction to 90° while providing resistance proximal to resistance against supination. Pain indicates possible bicipital tendinopathy or a the elbow (primary abductor: supraspinatus). Instruct the patient to externally rotate the shoulder while you provide resistance. Compare the strength of the involved shoulder  Type I: Sprain of the acromioclavicular or coracoclavicular ligament. A positive test consists of pain or weakness on  Type V: Gross disparity between the acromion and clavicle, which displaces resisting downward pressure on the arms or an inability to perform the tests. Acromioclavicular Joint  Crossed Arm Adduction test – Flex the shoulder to 90° and adduct arm across body (reaching for opposite shoulder).

If the patient feels apprehension that the arm may dislocate anteriorly, the test is positive. Typically of high quality as Conservative musculoskeletal care is typically care of first resort based on long standing randomization assures similarities of subjects within treatment groups. Typically ‘low tech,’ low cost, with minimal and rare side effects, it is frequently delivered in primary care settings, and by various health providers. The rigor and quality Observational Studies expected of high cost, higher risk, emerging, and tertiary interventions is less common for many routine physical examination procedures and conservative interventions. Thus, the committee allocate to treatment groups through the course of their care for a given occurrence of a has not presented explicit recommendations, rather, evidence summaries guided by expert condition. Larger, well-designed cohort studies may be of good quality, but lack of consensus to assist in formulating care options. Further, significant emphasis is made regarding randomization predisposes to heterogeneity issues within groups, some of which may be able to tracking and documenting meaningful functional improvement with patients. Cross sectional – Involves observing a population to measure disease and exposure status. It is usually thought to be a “snapshot” of the frequency and characteristics of a disease in a population at a specific given time. Assessing Study Methodologic Quality Case control – Is a study that compares patients who have an outcome (cases) of interest with patients who do not have the disease or outcome (controls). The study may retrospectively to Attributes of study methodology quality vary according to the clinical procedure (eg, diagnostic, compare how frequently the exposure was present in a group to determine risk factors.

Better designs use consecutive patients and include robust baseline and follow guide to systematic evidence review, quality attributes and consensus process that generally up outcome measures. Case reports – Describes an individual case, typically only achieving publication if it represent a unique or unusual clinical experience. General attributes identified when extracting evidence from studies include identification of population, the intervention and co-interventions and outcomes being addressed in each study. The clinical questions addressed such as diagnostic accuracy, therapeutic effectiveness, or Blinding causation are determined. Studies are extracted into evidence tables including quality attributes Blinding minimizes potential bias. Typically three levels of blinding are sought: patient, treating and/or ratings which are reviewed both by department staff and committee members (usually 2 provider and evaluator. At a minimum, single blinding of the evaluator as to what group a subject was in is expected. Specific quality attributes include: Diagnostic Accuracy – design, spectrum of patients, validity and relevance of outcome metric; Therapeutic Interventions – comparison groups (no treatment, Literature Reviews placebo, comparative intervention), treatment allocation, blinding/masking (method and degree: Quantitative systematic reviews – Studies that review previously published clinical trials that single, double, independent), follow-up (period and completion), and analysis (statistical power, include quantitative comparisons. Specific attention is paid to several factors including reporting of outcomes and comprehensive methodology to identify relevant published research and include appraisal (primary vs. Qualitative systematic reviews – Similar to quantitative reviews but without systematic quantitative comparison or data pooling.

The im pingement of the supraspinatus tendon leads to supraspinatus tendonitis, common site of the impingement occurs in under the acromion process and over the bursae. Clinical Anatomy [1,2] Figure 1 Clinical Presentation Patient presents with shoulder pain, especially with overhead activities and also pain level increased at night. According to occurrence and nature of pain it is differentiated in to two patterns. Supraspinatus Tendinitis and Physical Therapy Management 798 Causes [3,4] Extrinsic causes Intrinsic causes. Trauma (direct macrotrauma due to injury or repetitive microtrauma due to strain). Palpation: the entire shoulder girdle is palpated (noting tenderness, deformities, or atrophy) from the acromioclavicular joint, clavicle, glenohumeral joint, scapula, scapulothoracic articulation, anterior/posterior shoulder capsule, supraspinous fossa, in fraspinous fossa, and humerus, especially proximally.

All past and current members of its Ultrasound Advisory Group who have contributed to or commented on previously published documents available via The United Kingdom Association of Sonographers was set up to support sonographers, provide advice and practice guidance and ultimately get sonography recognised as a profession in its own right. It is a testament to the quality of the original Guidelines that some sections are relatively unchanged. Guidelines, however, need to keep in step with evolving technology, changes in practice and professional progression. For this reason it was decided to produce the revised version as a web-based document that can be regularly updated, amended and expanded as and when required. These revised Guidelines have been produced in collaboration with the British Medical Ultrasound Society. It has been both informative and enjoyable working with them and hopefully it is just the first of many similar future ventures. As with all previous editions, these Guidelines are not designed to be prescriptive but to inform good practice. May they continue to be used in departments across the United Kingdom for years to come. Wendy Williams Member, Ultrasound Advisory Group, Society and College of Radiographers. For the record these documents were: i) Guidelines for Professional Working Practice, published in December 1993 ii) Guidelines for Professional Working Practice Reporting, published in April 1995 iii) Guidelines for Professional Working Standards, published in August 1996 iv) Guidelines for Professional Working Standards Ultrasound, published in October 2001 v) Guidelines for Professional Working Standards-Ultrasound, published in October 2008 It has been designed as a web-based document and will only be available on-line for easier updating and to allow for active hyperlinks to other guidance documents and organisations to be provided. It is proposed that log-on requirements will be reviewed in due course once feedback and comments have been taken into account. There can be overlap between the terms ‘Standards’, ‘ Guidelines’ and ‘Protocols’ and this can cause confusion. Standards promote the likelihood of an ultrasound examination being delivered safely and effectively, are clear about what needs to be done to comply, are informed by an evidence base and are effectively measureable’. Guidelines provide recommendations on how ultrasound examinations should be performed and are based on best available evidence. They help ultrasound practitioners in their work but they do not replace their knowledge and skills’. Protocol: An agreement, preferably based on research, between practitioners to ensure the delivery of high quality standardised ultrasound examinations. The title of this 2015 edition ‘Guidelines for Professional Ultrasound Practice’ reflects the above definitions. These Guidelines, which are not prescriptive, are made available to be used as recommendations for good practice. The examination specific section, including guidelines and common clinical scenarios (ref: section 2) has been compiled by the British Medical Ultrasound Society Professional Standards team and is presented as examples of best practice. They have been included so that departments can use them as a basis to generate their own departmental examination protocols when there are no nationally agreed ones available. There are also sections giving general 5 guidance and advice, including reporting and audit. These guidelines do not and cannot cover all elements of an ultrasound examination and in addition ultrasound practitioners are advised to access standard texts, documents and research in order to fully inform local departmental protocols and procedures. Practitioners are referred to publications from the national fetal anomaly screening programmes, the Royal College of Obstetricians and Gynaecologists (especially their Greentop Guidelines), the Fetal Medicine Foundation, Association of Early Pregnancy Units, British Society of Gynaecological Imaging and the International Society of Ultrasound in Obstetrics and Gynaecology. The term patient has been used throughout the document in preference to other terms such as client or service user. Several professional titles are used by those who practice ultrasound and this can lead to considerable confusion. The term ultrasound practitioner is used throughout this document when appropriate to do so. The definition of ultrasound practitioner within the Glossary section of the above document is: ‘A healthcare professional who holds recognised qualifications in medical ultrasound and is able to competently perform ultrasound examinations falling within their personal scope of practice. The professional background of ultrasound practitioners can be very varied and will include radiologists, radiographers, sonographers, midwives, physiotherapists, obstetricians and clinical scientists’.

Posterior dislocations are less common, more difficult to diagnose and may mimic other shoulder conditions. Impingement Syndrome: Shoulder pain resulting from irritation of rotator cuff tendons and/or the subacromial bursa usually due to mechanical friction of these structures against bony structures. Labrum Tear: Typically an avulsion of the glenoid cartilage which rings the scapular surface of the shoulder joint. These Guidelines will be of relevance to all, hence the use of the term ‘ultrasound practitioner’ whenever possible. It does not imply that they hold recognised ultrasound qualifications as would an ultrasound practitioner’. It is the nature of any document whether published in a traditional format or on-line that it can very quickly become out of date. At the time of publication (December 2015), all hyperlinks have been checked and are complete. We would also like to again take this opportunity thank all the contributors and editors of previous editions of the Guidelines who have provided us with such a firm foundation on which to build. Sonographers are qualified healthcare professionals who undertake, report and take responsibility for the conduct of diagnostic, screening and interventional ultrasound examinations. Sonographers also perform advanced diagnostic and therapeutic ultrasound procedures such as biopsies and joint injections. The following definition of ‘sonographer’ is used in connection with the Public Voluntary Register of Sonographers: ‘A healthcare professional who undertakes and reports diagnostic, screening or interventional ultrasound examinations. They are either not medically qualified or hold medical qualifications but are not statutorily registered with the General Medical Council. Individuals without a recognised qualification, including student sonographers should always be supervised by qualified staff. A sonographer should: i) recognise and work within their personal scope of practice, seeking advice as necessary; ii) ensure that a locally agreed and written scheme of work is in place; iii) work with reference to national and local practice and guideline recommendations; iv) ensure they hold appropriate professional indemnity insurance or obtain this by virtue of their employment (ref: section 1. The general standards of education and training for ultrasound practitioners are set out on page 12 of the 2014 Royal College of Radiologists/Society and College of Radiographers document ‘Standards for the Provision of an Ultrasound Service’. The registration situation for sonographers is complex 1 the majority of sonographers are statutorily registered but this will depend on their professional background and is not achievable for all. Government policy since 2011 has been not to bring further aspirant groups into statutory registration unless there is a clear evidence of clinical risk that requires this. Autonomy and accountability for healthcare workers, social care workers and social care workers. The majority of statutorily registered ultrasound practitioners will already meet this requirement and will not need to take any further action. They will either work in an employed environment where their employer will indemnify them, and / or if they undertake self-employed work, they will have already made their own professional indemnity arrangements. However, some statutorily registered ultrasound practitioners may need to take steps to make sure that they have appropriate professional indemnity arrangements in place. Registrants and applicants for statutory registration will be asked to confirm that they meet, or will meet, this requirement by completing a professional declaration when renewing or registering for the first time. Ultrasound practitioners who are self employed or who work in a part employed, part self-employed environment are particularly advised to read the guidance published by their statutory regulator. There is no professional indemnity insurance associated with voluntary registration on the Public Voluntary Register of Sonographers. If an ultrasound practitioner is not statutorily registered, it is clearly good practice to ensure that they have appropriate professional indemnity arrangements in place both to protect the public and themselves. There is published advice on education and training available to those who use ultrasound in this way but whose main work and role is not that of an ultrasound practitioner. For those who use the professional title of ‘sonographer’, ultrasound is their daily work and their primary profession. When used as a ‘tool’, ultrasound aids and assists a healthcare practitioner with their wider examination and treatment, but in overall terms, ultrasound is only a small part of their work. It is important for safe and effective service delivery that all ultrasound examinations are undertaken by appropriately trained and competent personnel and that there is associated audit and continuing professional development in the use of ultrasound. There is no evidence that diagnostic ultrasound has produced any harm to patients in the four decades that it has been in use. However, the acoustic output of modern equipment is generally much greater than that of the early equipment and, in view of the continuing progress in equipment design and applications, outputs may be expected to continue to be subject to change. Also, investigations into the possibility of subtle or transient effects are still at an early stage. Consequently diagnostic ultrasound can only be considered safe if used prudently’. Doppler imaging and measurement techniques may require higher exposures than those used in B and M-modes, with pulsed Doppler techniques having the potential for the highest levels. Recommendations related to ultrasound safety assume that the equipment being used is designed to international or national safety requirements and that it is operated by competent and trained personnel. It is the responsibility of the operator or ultrasound practitioner to be aware of, and apply, the current safety standards and regulations and to undertake a risk/benefit assessment for each examination. Key principles for the safe use of ultrasound: 2 i) Medical ultrasound imaging should only be used for medical diagnosis. Their content should address the ultrasound examinations, their reporting and the appropriate referral pathways for patients with normal and abnormal ultrasound findings. The details in the protocols should be such that a new staff member, having read them, could carry out and report these examinations and appropriately refer the patient after the examination to the expected standard. Protocols should be updated regularly and their review date should be included in their content. Records are currently required by law to be kept for a number of years as specified by Department of Health advice (ref: section 2. Examples would be the image storage requirements of the abdominal aortic aneurysm and fetal anomaly screening programmes and those published by the Department of Health. It advises ministers in all four countries and is part of Public Health England, an executive agency of the Department of Health. Guidance on when ultrasound examinations of the neonatal hip should be performed can be found at. Public Heath England advice on private screening for different conditions and diseases. Information outlining the advantages and disadvantages of screening outside the national programmes can be found via the following web link. There is information and leaflets available for healthcare professionals and links to leaflets written for patients. There are several causative factors including high workloads, increasing body mass index of patients, poor equipment 13 and room design and poor posture when scanning. It is important that ultrasound practitioners take care of themselves and their working environment whilst scanning. Employers have a legal duty of care to their employees and should be guided in ways to avoid potential work related injuries i. Many advice and guidance documents have been published to which ultrasound practitioners are referred: Health and Safety Executive Risk management of musculoskeletal disorders in sonography work (2012). Manufacturers can set these up to your requirements at the time of installation and will optimise features such as transducer frequency and harmonics. Firm pressure may be contra-indicated for some types of pathology or clinical situations. In addition, some patients may have a clear preference for a health carer of specific gender due to their ethnic, religious or cultural background, because of previous experiences or in view of their age. Where possible such individual needs and preferences should be taken into consideration. When required, private, warm, comfortable and secure facilities for dressing and undressing should be provided. Care should be taken to ensure privacy in waiting areas used by patients not fully dressed in their own clothes. During the ultrasound examination, only those body parts under examination should be exposed. Care must be taken to maintain confidentiality when non-health care personnel are nearby. Patients should be given the opportunity to have a chaperone, irrespective of the ultrasound practitioner’s gender and the examination being undertaken. The ultrasound practitioner should give equal consideration to their own need for a chaperone, again irrespective of the examination being undertaken or the gender of the patient. A record should be made in patient records when chaperones are offered and used, and when they are declined. Chaperones should normally be members of the clinical team who are sufficiently familiar with the ultrasound examination being carried out to be able to reliably judge whether the ultrasound practitioner’s actions are professionally appropriate and justifiable. Patients’ privacy and dignity should be maintained throughout the examination which should be conducted without interruption. There are several organisations that have produced advice on the conduct of intimate examinations and also on the use and role of chaperones. Society and College of Radiographers (2011) Intimate Examinations and Chaperone Policy. Time needs to be allowed for room preparation, assessing the ultrasound request, introductions, explanations, obtaining consent and assisting the patient when necessary on to and off the examination couch. Post procedure time is required to discuss the findings with the patient, write the report, archive the images and attend to the after-care of the patient, including making arrangements for further appointments and/or further investigations. An ultrasound practitioner has a professional responsibility to ensure that the time allocated for an examination is sufficient to enable it to be carried out competently. It is critical to patient management that no ultrasound examination is compromised by departmental and or government targets. It may also be influenced by the expertise of the ultrasound practitioner and training commitments within the department. In addition, the duration of the examination will be further influenced by the scan findings and/or the physical condition of the patient. Examination times will need to take into account whether there are trainees present and their stage of training if teaching is to be effective. The time allocation for appointments to meet these requirements is a minimum of twenty (20) minutes. The time allocation for appointments to meet these requirements for a singleton pregnancy is a minimum of thirty (30) minutes and for a multiple pregnancy is forty five (45) minutes. The Society and College of Radiographers has published guidance on examination times at. Individual departments can determine examination times taking into account local circumstances. Many request forms are very non-specific in terms of the patient’s symptoms and due allowance may need to be made for this in schedule planning if it is decided to proceed (Ref: sections 2. For example, it may be necessary to perform both transabdominal and transvaginal scans to fully evaluate the female abdomen and pelvis with ultrasound. Valid informed consent must be obtained before commencing any ultrasound examination or procedure. Ultrasound practitioners who do not respect the right of a patient to determine what happens to their own body in this way may be liable to legal or disciplinary action. The consent process is a continuum beginning with the referring health care professional who requests the ultrasound examination and ending with the ultrasound practitioner who carries it out. It is the responsibility of the referring professional to provide sufficient information to the patient to enable the latter to consent to the ultrasound examination being requested. It is the responsibility of the ultrasound practitioner to ensure that the patient understands the scope of the ultrasound examination prior to giving his or her consent. Additional informed verbal consent should be obtained where a student ultrasound practitioner undertakes part or all of the ultrasound examination under supervision. Verbal informed consent for those examinations of an intimate nature should be recorded in the Ultrasound report. Some categories of ultrasound examination (interventional ultrasound, guided procedures. The following are all relevant: Royal College of Radiologists Standards for patient consent particular to radiology (2012). By safeguarding high standards of care and seeking to continuously improve its quality, it ensures that health care provision is patient centred which is central to the concept. The main components of a clinical governance framework can be summarised as follows: 3 i) Risk management ii) Clinical audit iii) Education, training and Continuous Professional Development iv) Patient and carer experience and involvement v) Staffing and staff management An example of published Trust information on clinical governance can be found at. This will include audit of ultrasound examinations and reports: participation in multi-disciplinary team meetings and radiology discrepancy meetings would be further examples; ii) Communication and consent: (ref: section 1. This is of particular importance following the publication of the Francis Report in 2013 4 (ref: section 1. In 2008 the National Ultrasound Steering Group published a document entitled ‘Ultrasound Clinical Governance’. The National Ultrasound Steering Group was a short-term sub-group of the National Imaging Board. Next is team based regulation which reflects the importance of acting if a colleague’s conduct or performance is putting patients at risk.

The penicillin molecule has a core compared with individuals skin test negative to the full set of major and minor penicillin determinants. Under physiologic conditions, based on the available literature, skin testing with penicilloyl the -lactam ring opens spontaneously, allowing the carbonyl polylysine and penicillin G appears to have adequate negative group to form an amide linkage with amino groups of lysine predictive value in the evaluation of penicillin allergy. The most important of are applied by the prick/puncture technique, and if these these are penicilloate and penilloate, and they, along with results are negative, intradermal testing should be performed. Penicillin skin testing, using the reagents de plained by the fact that patients with convincing reaction scribed above and proper technique, are safe with only a rare histories lose their sensitivity over time. Of 239 patients with initially negative peni repeat penicillin skin testing is not indicated in patients with cillin skin test results, 6 patients (2. In a previous study, treatment with penicillin appears to be more likely; there among 614 patients without a history of penicillin allergy, 51 fore, repeat penicillin skin testing in this situation may be (8. Penicillin skin testing may be performed elec penicillin skin test–positive patients showed positive re tively (when patients are well and not in immediate need of sponses to only penicilloylpolylysine. Arguments in favor of elective penicilloylpolylysine is poor, and, in that situation, elective skin testing include the fact that penicillin skin testing in the penicillin skin testing is not recommended. Also, in remote acute setting when a patient is ill is more difficult to accom areas, clinicians may not have access to an allergist/immu plish in a timely fashion. Consequently, such patients are nologist to perform penicillin skin testing even if appropriate treated with alternate antibiotics,19,374,376,393 many of which, reagents are available. Overuse of broad-spectrum antibiotics is known to history and likelihood of needing treatment with penicillins. Patients with convincing reaction course of penicillin (in skin test–negative individuals) to histories are more likely to be allergic than patients with induce resensitization and hence the need to repeat penicillin vague reaction histories. Surveys of patient with cillin specific IgE antibodies wane over time, and therefore negative penicillin skin test results (without subsequently patients with recent reactions are more likely to be allergic being challenged with penicillin) found that a large propor than patients with distant reactions. Approximately 50% of tion was not treated with -lactam antibiotics because of fear patients with IgE-mediated penicillin allergy lose their sen on either the part of the patient or the treating physician.

A negative cephalosporin skin test (using a cephalosporins is infrequent, anaphylactic reactions after ad nonirritating concentration) does not rule out the presence of ministration of cephalosporin have occurred in patients with drug specific IgE antibodies. Before 1980, penicillin degraded products not used in the testing may be present but allergy history–positive and skin test–positive patients who not detectable. Therefore, because the negative predictive were given cephalosporins had a reaction rate of approxi value of cephalosporin skin testing is unknown, a cautious 430,437 mately 10% to 20%.

Cephalosporin Administration to Patients With a If patients with a history of allergy to penicillin are not skin tested but given cephalosporins directly, the chance of a History of Penicillin Allergy (Figure 2) reaction is probably less than 1%. This figure is based on the Summary Statement 97: Since 1980, studies show that fact that only approximately 10% of penicillin history–posi approximately 2% of penicillin skin test–positive patients 17,18 tive patients have positive skin test results, and of those, react to treatment with cephalosporins, but some of these 22,438-440 only 2% will react to a cephalosporin.
