Accuracy of Provider Predictions of Viral Suppression Among Adolescents and Young Adults With HIV in an HIV Clinical Program

BACKGROUND

Providers caring for adolescents and young adults with HIV (AYA-HIV) mostly base their adherence counseling during clinical encounters on clinical judgment and expectations of patients' medication adherence. There is currently no data on provider predictions of viral suppression for AYA-HIV. We aimed to assess the accuracy of provider predictions of patients' viral suppression status compared to viral load results.

METHODS

Providers caring for AYA-HIV were asked to predict the likelihood of viral suppression of patients before a clinical encounter and give reasons for their predictions. Provider predictions were compared to actual viral load measurements of patients. Patient data were abstracted from electronic health records. The final analysis included 9 providers, 28 patients, and 34 observations of paired provider predictions and viral load results.

RESULTS

Provider prediction accuracy of viral suppression was low (59%, Cohen's Kappa = 0.16). Provider predictions of lack of viral suppression were based on nonadherence to medications, new patient status, or structural vulnerabilities (e.g., unstable housing). Anticipated viral suppression was based on medication adherence, history of viral suppression, and the presence of family or other social forms of support.

CONCLUSIONS

Providers have difficulty accurately predicting viral suppression among AYA-HIV and may base their counseling on incorrect assumptions. Rapid point-of-care viral load testing may provide opportunities to improve counseling provided during the clinical encounter.

Preparing the Frontlines: Delivering Special Pathogen Training to Maryland Hospital Staff

Healthcare workers (HCWs) at community hospitals, also known as frontline hospitals (FLHs), may encounter patients with possible infectious diseases, including those caused by high-consequence pathogens such as Zaire ebolavirus. We created and piloted a 1-day, in-person, didactic and skills training program to determine the feasibility and acceptability of implementing an educational program to enhance the knowledge and skills needed to respond when a patient with a potential high-consequence pathogen presents to an FLH. The Maryland Department of Health queried all 104 state FLHs to identify their interest in participating in the pilot training program. HCWs from 12 (75%) of the 16 interested FLHs participated in the program before it was interrupted by the COVID-19 pandemic. In addition to pathogen-specific training based on the Identify, Isolate, and Inform framework, we provided skills training in the proper use of personal protective equipment, spill cleanup, and removal of an incapacitated HCW from an isolation area. We conducted a paired pretraining and posttraining knowledge assessment and measured a significant learning gain among 135 participants (2-tailed t test, P<.05). Over 95% of the participants reported that the training was relevant to their daily work and the clinical simulations and reference material were useful and appropriate for their learning level. Findings from this pilot program demonstrated the feasibility and acceptability of a 1-day combined didactic and skills training program focused on high-consequence pathogens. We plan to reengage the original FLHs and add regional FLHs in an updated training effort based on our findings.

A qualitative analysis of health information-sharing networks in the Indonesian poultry sector

Animal production systems are developing into increasingly complex value chains involving a large diversity of actors with multiple and dynamic linkages, concurrently creating many opportunities for disease spread. Access to timely and good-quality animal health information is vital for designing effective disease management strategies. However, several factors may hamper information flows along those chains. Understanding the structure and dynamics of information networks is essential to develop effective and acceptable health information systems. We applied a qualitative network approach to understand how information about poultry health is generated, disseminated and used for decision-making along the poultry value chain in Indonesia. Maps of the value chain and information networks were generated based on data from key informant interviews to illustrate the linkages and information-sharing patterns between stakeholders. Four types of farm business models were identified: company-owned, contract, partnership and independent. Although companies and most independent farmers collected health and production data routinely, their systems were strongly siloed and still relied on a mix of digital and paper-based methods, which impaired their analytical capacity. Technical service providers from the upstream sector and industry associations were identified as key intermediaries in the information-sharing network with the ability to create informal bridges between separate business networks and public actors. These actors can play a strategic role in the development of integrated information systems to improve stakeholders' capacity to monitor, anticipate and manage disease threats at all levels of the value chain. This study contributes to fill an important knowledge gap regarding the layer sector and may help decision-makers to design effective policies and interventions tailored to the type of business model.

Implementation and Effectiveness Outcomes of a Quality Improvement Intervention to Strengthen the Application of the World Health Organization Surgical Safety Checklist Tool in a Limited-Resource Setting

BACKGROUND

There is a disparity in the provision of quality and safe surgical care in Nigeria. The capacity to track surgical safety through the use of the surgical safety checklist tool is variable in this setting. This study aimed to assess the outcomes of training on this checklist and the results of its pilot implementation.

SUBJECTS, MATERIALS AND METHODS

A mixed-methods research comprising of quantitative and qualitative study designs was conducted to evaluate these 23 weeks intervention in our centre. Implementation was conducted in two phases: training of the surgical team and pilot testing of the intervention. Using the RE-AIM framework, implementation outcomes evaluated included reach of training, adoption of checklist and implementation challenges, while effectiveness outcomes evaluated included change in the knowledge score after the training and self-reported impact of the training and pilot test. Quantitative and qualitative data were collected and analyzed.

RESULTS

There was a 2.4-point significant increase in the knowledge score after the training. During the pilot testing phase, 843 patients had surgery. The weekly checklist utilization rate for elective surgery rose to 64% at project completion. Despite logistic and manpower-related implementation challenges, the training intervention facilitated the translation of participant knowledge into practice (81.5%) and the pilot phase had a high impact on the practice of checklist use (3.8 ± 0.9).

CONCLUSION

The quality improvement programme enhanced knowledge of checklist use and led to improved behaviour and positive organizational change. However, barriers need to be addressed to strengthen the sustainable use of the checklist tool.

Editorial: The WHO Global Oral Health Action Plan 2023-2030

Oral health is finally on the global agenda. The World Health Organisation Global Oral Health Action Plan (OHAP) 2023-2030 (WHO, 2022a) has been completed following a public consultation which took place during August and September 2022. As oral diseases are the most prevalent non-communicable diseases; it is good to see that the OHAP will co-exist alongside the Global Action Plan for the Prevention and Control of Non-communicable Diseases 2013-2030. This editorial summarises the OHAP and highlights the opportunities and challenges discussed during the September 2022 EADPH congress, held co-jointly with the Council of the European Chief Dental Officers (CECDO).

The WHO Action Plan for Oral Health - How Can the EADPH Contribute - Opportunities and Challenges

This paper summarises the proceedings of a workshop organised by the European Association of Dental Public Health, held in Montpellier in September 2022. The full proceedings were transcribed and are available on the Community Dental Health website (https://www.cdhjournal.org/article/973). The WHO Action Plan for Oral Health provides a golden opportunity to help raise the profile of oral health, to put oral health on the global public health agenda and ultimately improve oral health. It is to be applauded. However, delivery will present a challenge. Those challenges and opportunities are detailed in this paper.

Management of Pelvic Inflammatory Disease in Clinical Practice

Pelvic inflammatory disease (PID) is a common reproductive health disorder among women of reproductive age. The treatment of PID has slowly evolved, reflecting changing antibiotic susceptibility and advancements in therapeutics and research; however, it has been largely unchanged over the last several decades. The most recent treatment recommendations consider the severity of infection, clinical presentation, and the polymicrobial nature of the disease. In addition, the role of novel organisms like Mycoplasma genitalium in PID is of emerging significance. PID treatment guidance offers oral and parenteral treatment options based on the patient's clinical status; however, deviations from the published guidelines are a general concern. Point of care (POC) testing for precision care, provision of adherence support, optimizing self-management and prevention strategies, and other alternative or synergistic approaches that maximize treatment outcomes will be instrumental for addressing the current challenges in PID diagnosis and management.

Understanding Perceived Risks and Sexual Behavior Among Adolescents and Young Adults During the COVID-19 Pandemic

PURPOSE

We sought to describe the relationship between COVID-19 risk perception and sexual behaviors among urban adolescents and young adults (AYA).

METHODS

Data were collected from 159 urban AYAs on COVID-19 risk perception, COVID-19 infections and deaths, romantic relationships, and sexual behavior during the stay-at-home order using a telephone survey.

RESULTS

Seventy-nine percent of the study participants engaged in sexual intercourse during the stay-at-home order. Only 38% of these used condoms during their last sexual encounter. Experiencing COVID-19 positivity within their social circle was not related to COVID-19 testing. Concern for COVID-19 infection or experiencing a COVID-19 diagnosis or death in one's social circles was not associated with sexual intercourse or condom use.

DISCUSSION

Urban AYA remained at risk for sexually transmitted infections, and COVID-19, given high baseline community rates of sexually transmitted infections and COVID-19, low condom use, and low COVID-19 risk perception at the time of the survey.

The Impact of Oral Health Training on the Early Year's Workforce Knowledge, Skills and Behaviours in Delivering Oral Health Advice: A Systematic Review

OBJECTIVES

To determine the effectiveness of training the early year's workforce on their knowledge, skills and/or behaviours in delivering oral health advice.

METHODS

Four databases: PubMed, Web of Science, Embase and Scopus were searched to evaluate the effectiveness of oral health training on knowledge, skills and behaviour of the early year's workforce with a minimum of one-month follow-up. Randomised or quasi-randomised trials and before and after studies were included.

RESULTS

All six included studies showed improved knowledge and one of the five studies showed significant changes in behaviours of participants post oral health training. None of the included studies addressed changes in skills as an outcome.

CONCLUSION

This systematic review found evidence that oral health training of the early year's workforce is effective in improving their knowledge but not necessarily their behaviours delivering oral health advice. Although training of the wider workforce on oral health is recommended, high quality research is required with longitudinal follow-up to assess changes in behaviours and ultimately impacts on oral health.

Realizing the promise of long-acting antiretroviral treatment strategies for individuals with HIV and adherence challenges: an illustrative case series

BACKGROUND

Adherence to antiretroviral treatment (ART) remains the cornerstone of optimal HIV outcomes, including viral suppression (VS), immune recovery, and decreased transmission risk. For many people with HIV (PWH), particularly those with early-acquired HIV, structural, behavioral, and cognitive barriers to adherence and competing priorities related to life events may be difficult to overcome, resulting in nonadherence. Long-acting injectable antiretroviral therapies (LAI-ART) may be a useful strategy to overcome some of these barriers. However, to date, the approved LAI-ART strategies (e.g., cabotegravir and rilpivirine (CAB/RPV)) have targeted those who have already attained viral suppression, precluding their use in the 40% of adolescents and young adults (AYA) that VS has eluded.

CASE PRESENTATION

Ms. X is a 30-year-old woman with perinatally-acquired HIV and barriers to adherence. Despite many interventions, she remained persistently viremic, with resultant immune suppression and multiple comorbid opportunistic conditions, and viral load (VL) > 10,000,000 copies/ml. Given her longstanding history of poor adherence to an oral regimen, a switch to monthly intramuscular (IM) injections and biweekly infusions of ibalizumab were initiated leading to decreased viral load to 8,110 copies/ml within two weeks. Ms. H is a 33-year-old woman with cognitive limitations due to childhood lead poisoning. Her viral load trajectory took a downward turn, precipitated by various life events, remaining elevated despite intensive case management. Initiation of LAI-ART (CAB/RPV) in this patient led to an undetectable VL (< 20 copies/ml) within two months of treatment initiation. Miss Y. is a 37-year-old woman with perinatally-acquired HIV and chronic challenges with nonadherence and longstanding immunosuppression with CD4 < 200 cells/mm³ for > 5 years. She received a 1-month oral lead-in (OLI) of cabotegravir/rilpivirine, followed by the injectable loading dose. She has since adhered to all her monthly dosing appointments, sustained VS, and transitioned to a bi-monthly injection schedule.

CONCLUSION

These three individuals with HIV (perinatally and non-perinatally acquired) with longstanding nonadherence and persistent viremia were successfully initiated on LAI-ART through the process of care coordination and the collective efforts of the care team, highlighting the barriers, challenges, and the multidisciplinary coordination needed to assure successful implementation of this strategy for the most vulnerable of patients.

Social Media Versus Traditional Clinic-Based Recruitment for a Dyadic Sexually Transmitted Infection Prevention Trial: Results From the Sexperience Study

BACKGROUND

The enrollment of youth in clinical trials has generally been achieved through conventional in-person recruitment but is evolving with the surge in the use of social media and presents an alternative resource for research recruitment for sexually transmitted infection (STI) prevention trials.

PURPOSE

To compare the direct costs and performance of social media recruitment versus clinic-based recruitment method for a dyadic behavioral intervention for STI among heterosexual couples.

METHODS

In the clinic-based recruitment arm spanning 60 weeks, patients aged 16-25 years were recruited through an adolescent/young adult clinic. Social media adverts targeting college students within the city were also posted online over 23 weeks, using Facebook ad software. We compared the direct costs and performance of both recruitment methods to assess feasibility.

RESULTS

Three hundred eighty-one individuals were approached, of which 21 completed the dyadic intervention (11 from social media-based recruitment and 10 from clinic-based recruitment). Clinic-based recruitment accounted for 91.0% of total recruitment cost and 9.9% of the total cost was spent on social media recruitment via Facebook ad.

CONCLUSIONS

Recruitment of adolescents and young adults for a dyadic behavioral STI intervention trial using social media is feasible, has lower direct costs, and results in similar outcomes compared to clinic-based recruitment.

The impact of HPV vaccination on the prevention of oropharyngeal cancer: A scoping review

INTRODUCTION

HPV-associated oropharyngeal cancer (OPC) has one of the most rapidly rising incidences of any cancer in high-income countries. HPV vaccination is being tested to prevent HPV-associated OPC.

OBJECTIVE

To determine the effect of Human Papilloma Virus (HPV) vaccination on the prevention of OPC in adults worldwide.

BASIC RESEARCH DESIGN

Scoping review conducted using PRISMA-ScR Checklist.

METHOD

An electronic literature search identified relevant records. Titles and abstracts were screened to assess eligibility by two researchers, and data from relevant full-text articles were extracted and synthesised.

RESULTS

Three-hundred-and-forty-three studies were identified, with eleven articles meeting the inclusion criteria. The most common study design was cross-sectional (n = 7), the most common location was the US (n = 6) and data collection periods spanned 2004 to 2020. One article found unvaccinated participants had a 19 times increased risk of developing OPC compared with those who had been vaccinated against HPV. The remaining papers showed that prevalence of HPV-vaccine-type oral infection was significantly lower in vaccinated participants than unvaccinated participants, with a reduction of oral HPV detection ranging from 72% to 93%. This reduction varied by sex.

CONCLUSIONS

There is evidence to suggest that HPV vaccination reduces oral HPV infection and decreases the incidence of HPV-associated OPC. There is substantial need for further research which directly examines the relationship between HPV vaccination status and subsequent OPC development.

Adolescents and young adults with early acquired HIV infection in the united states: unique challenges in treatment and secondary prevention

INTRODUCTION

Worldwide, children who acquired human immunodeficiency virus (HIV) at an early age, either perinatally or through blood transfusion, are reaching adolescence and adulthood due to successful antiretroviral treatment (ART). While many are thriving, a significant proportion face unprecedented multilevel challenges that can affect their long-term outcomes. Specifically, longstanding and poorly controlled HIV resulting from inadequate early regimens and nonadherence, along with the toxicities of some ART agents, can predispose them to sequelae including HIV-associated complications and other comorbidities.

AREAS COVERED

This paper reviews and summarizes the unique issues facing adolescents and young adults with early acquired HIV (AYA-EAHIV), including ART challenges, emerging comorbidities, and complications, including mental health comorbidities, secondary prevention, and transition from pediatric/adolescent to adult care.

EXPERT OPINION

AYA-EAHIV are a special population that have lived their entire lives with the physical and psychological toll of HIV mandating targeted and purposeful approaches to optimize their management and outcomes. Multifaceted inclusive and context-specific approaches focusing on heightened research, risk reduction interventions, and 'outside the box' thinking will be required to optimize treatment and reduce morbidity and mortality.

HIV Preexposure Prophylaxis Among Adolescents in the US: A Review

IMPORTANCE

Many adolescents and young adults in the US are disproportionately affected by HIV. Several others who are uninfected are at risk and in need of effective preventive strategies. The uptake rate of preexposure prophylaxis (PrEP) for HIV prevention has remained low among US adolescents. This review assesses the current status of PrEP uptake among at-risk adolescents aged 13 to 19 years and recommendations for improving PrEP access, uptake, and future needed directions, including specific recommendations for health care professionals.

OBSERVATIONS

Of the 37 377 new HIV diagnoses made in 2018, 7734 diagnoses (21%) occurred in adolescents and young adults aged 12 to 24 years; of these, 1707 diagnoses (22%) occurred in adolescents aged 13 to 19 years. The greatest burden of HIV is found among young African American men who have sex with men, accounting for two-thirds of all HIV infections in adolescents and young adults. Preexposure prophylaxis awareness and engagement are lowest in adolescents with the greatest risk for HIV. Adolescent primary care clinicians and specialists do not routinely offer HIV testing as recommended by the Centers for Disease Control and Prevention or routinely assess sexual risk exposures of patients through sexual history taking. Clinicians' decision to prescribe PrEP for adolescents is often guided by their perceptions of the patient's HIV risk and their knowledge and acceptance of PrEP guidelines. State laws on consent, confidentiality, and the rights of the adolescent to independently access PrEP outside of parental influence differ across jurisdictions, often limiting access and uptake.

CONCLUSIONS AND RELEVANCE

Use of PrEP in adolescents at risk for HIV is an important component of HIV prevention. Optimizing uptake includes improving clinicians' knowledge about HIV risk and prevention strategies, enhancing sexual history taking and risk assessment through training and retraining, and improving PrEP knowledge and acceptance of prescribing among clinicians. Leveraging the ubiquity of social media, encouraging family support, and performing research aimed at finding lifestyle-congruent formulations can help mitigate HIV transmission in adolescents at greatest risk for HIV.

0807 NREM Parasomnias: Retrospective Analysis Of Treatment And Outcomes

Introduction

NREM parasomnias are relatively common among children and sometimes persist in adulthood. These behaviors may result in injury or have negative impacts on functioning and quality of life thus necessitating treatment. The treatment is challenging given the lack of evidence for frequently used medications such as benzodiazepines (BDZ) or tricyclic antidepressants (TCA). The aim of this retrospective analysis is to determine the most frequently prescribed medications for treatment of NREM parasomnias and evaluate reported outcomes.

Methods

We performed a retrospective chart review of all patients with NREM parasomnia diagnosed within BWH clinics examining the date of diagnosis, date of starting therapy, comorbidities, type of medication prescribed, and the reported change in symptoms or side effects at the individual’s follow-up visits.

Results

From 2012 to 2019, 123 patients (64 females, 59 male) at BWH clinics received the diagnosis of NREM parasomnia, including sleepwalking and night terrors. Mean age was 44. Comorbidities included depression=16, anxiety=32, seizures=6, RLS=9, epilepsy=5, insomnia=29, and OSA=57. Initial treatment included safety counseling (72), BDZ (7), TCA (4), and treatment of comorbidity (23). Treatment of OSA only (n=15) was effective in 66% (n=10) and 33% were lost to follow up. Of those with OSA treatment plus BDZ (n=6), treatment was effective in 50% (n=3). Of those receiving BDZ only (n=7), treatment was effective in 43%. Of those receiving Melatonin (8),treatment was effective among 62.5% (n=5). TCAS (n=4) were effective in 3 patients (75%). Treatment of comorbid conditions without pharmacotherapy (23) was effective in 35% (n=8) while the remaining 65% (n=15) were lost to follow up.

Conclusion

Treating comorbid conditions such as OSA, insomnia, RLS, depression, and anxiety is a frequent treatment strategy. Additional pharmacologic treatment most commonly includes melatonin, BDZs, and TCAs.

Associations of macro and micronutrients and antioxidants intakes with preeclampsia: A case-control study in Jordanian pregnant women

BACKGROUND AND OBJECTIVES

A study was conducted to evaluate whether preeclampsia in pregnant women is associated with dietary factors and antioxidant intake (vitamin C, vitamin E, vitamin A, and selenium).

METHODS AND RESULTS

In this case-control study, a group of 79 pregnant Jordanian women (36 preeclamptic pregnant women and 43 healthy pregnant women aged 18-45 years with a gestational age ≥20th week of pregnancy) were recruited from the obstetrics and gynecology clinics at Royal Medical Services, King Hussein Medical Center, Amman, Jordan. Information about socio-demographics, anthropometric measurements, biochemical measurements, nutritional intake, and dietary habits was collected through a structured interview. Three 24-hour dietary records were also made. Data were analyzed using Statistical Package for the Social Sciences (SPSS), and dietary intake was analyzed using ESHA software. Prepregnancy BMI, age, multiple pregnancies, energy intake, beta-carotene, vitamin C, and sodium showed significant difference between preeclamptic pregnant women and healthy pregnant women. The odds ratio (OR) and the corresponding 95% confidence interval (CI) show that a strong association with preeclampsia exists for the intake of fat (OR = 6.40, 95% CI: 1.85-22.17) and saturated fat (OR = 3.35, 95% CI: 1.0-11.54). Inverse associations with preeclampsia were found for fruit intake (OR = 0.16, 95% CI: 0.47-0.55) and olive oil intake (OR = 0.20, 95% CI: 0.05-0.78).

CONCLUSION

In this case-control study in Jordanian pregnant women, preeclampsia was associated with a high intake of fat, saturated fat, and sodium and a low intake of fruits, fiber, vitamin C, B-carotene, and olive oil.

Research participation among state and local public health emergency preparedness and response programs

OBJECTIVES

The objective of our study was to assess whether state and local health staff participated in public health emergency preparedness research activities and what partner organizations they collaborated with on research.

STUDY DESIGN

This is a cross-sectional study.

METHODS

Data were derived from a 2014 web-based survey of state, territorial, and local health departments conducted by the Centers for Disease Control and Prevention and NORC at the University of Chicago as part of a larger project to assess the public health emergency preparedness and response research priorities of state and local health departments.

RESULTS

Overall, 30% of survey respondents indicated that health department staff were involved in public health preparedness and response research-related activities. Thirty-four percent indicated that they were extremely or moderately familiar with emergency preparedness research and literature. Approximately 67% of respondents reported interest in receiving additional information and/or training related to the preparedness research and literature. The most frequently reported partners for collaboration in preparedness research-related activities were schools of public health (34%).

CONCLUSIONS

Our findings suggest that there is health department interest in learning more about preparedness and response science and that additional efforts are needed to increase health department participation in public health emergency preparedness and response research-related activities.

Evaluation of a pilot oral health promotion programme 'Keep Smiling': perspectives from GDPs, health champions and school staff

OBJECTIVE

To evaluate a pilot oral health promotion programme (fluoride varnish and tooth brushing), targeting 3-7-year-olds in primary schools in a deprived area of London.

METHOD

A pilot programme was conducted among five primary schools targeting 3-7-year-old children in a deprived area of London. The programme consisted of a fluoride varnish application and tooth brushing sessions. Outcome (participation rates) and process evaluations were carried out using semi-structured interviews with school staff, health champions and dentists.

RESULTS

Overall, 79.2% of the targeted children participated in tooth brushing and 68.6% of children received fluoride varnish. The programme received positive feedback from school staff, dental teams and health champions. It raised awareness of dental health among all stakeholders and provided children with a unique experience, creating a positive image of dental teams.

CONCLUSIONS

Community engagement and collaboration between health, education and the voluntary sector is feasible and integral in developing oral health promotion programmes aimed at children attending primary schools in a deprived area of London.

Evaluation of analgesic and anti-inflammatory effects of ethanol extract of Ficus iteophylla leaves in rodents

This study was undertaken to investigate the leaf part of the plant for analgesic and anti-inflammatory. The ethanol extract of Ficus iteophylla leaves (100, 200, and 400 mg kg(-1), i.p) was evaluated for analgesic and anti-inflammatory activities. The analgesic effect was studied using acetic acid-induced abdominal constriction and hot plate test in mice, while the anti-inflammatory effect was investigated using carrageenan induced paw oedema in rats. The ethanol extract at 100 mg kg(-1), 200 mg kg(-1), and 400 mg kg(-1) significantly (P< 0.05) inhibited acetic acid induced writhes by 1.50 ± 0.43, 3.0 ± 0.82 and 1.0 ± 0.82 respectively. It also exhibited significantly (P< 0.05) anti-inflammatory by 0.11 ± 0.02, 0.11 ± 0.03, 0.08 ± 0.01 respectively. The preliminary phytochemical screening of the plant extract revealed the presence of flavonoids, steroids, tannins and saponins while the effect of flavonoids, steroids and tannins on analgesic and inflammatory has been reported. The intraperitoneal median lethal dose (LD(50)) value of the extract was found to be 3807.8 mgkg(-1) body weights. The result obtained from this study shows that the extract of Ficus iteophylla contained phytochemical constituents with analgesic and anti-inflammatory activities, therefore the leaf part of the plant could be used in the management of pain and inflammatory conditions.

Bleeding after dental extractions in patients taking warfarin

OBJECTIVE

To assess the incidence of bleeding after dental extractions in subjects taking warfarin continuously before and after extractions whose International Normalised Ratio (INR) was below 4.0 at the time of extraction.

METHODS

This was a case series study of 150 patients without controls who required extraction of at least one tooth under local anaesthetic. All sockets were subsequently packed with absorbable oxycellulose and sutured.

RESULTS

A total of 58 women and 92 men were included (mean age 66 years); their ages were similar. The mean INR (S.D.) was 2.5 (0.56), although most patients had an INR less than 2.5 (n=101). Ten patients (7%) bled after extraction, enough to require a return to hospital. Five patients of 101 with an INR</=2.5, and 5 with an INR>2.5 out of 49 bled after extraction (p=0.29). Bleeding after extraction was not associated with operative antibiotics. All patients who bled were managed conservatively and none was admitted to hospital.

CONCLUSION

Patients taking warfarin whose INR is up to 4.0 and who have dental extractions in hospital do not have clinically significant bleeds post-operatively.

Oral submucous fibrosis in a 12-year-old Bangladeshi boy: a case report and review of literature

Oral submucous fibrosis is commonly seen in the adult population of the ethnic minorities in the UK, although its presentation in a child is rare. Whilst the condition is considered multifactorial and irreversible, we present a case of oral submucous fibrosis in a 12-year-old Bangladeshi boy whose cessation of habitual betel nut chewing and forcible mouth chewing exercises led to an improvement in his mouth opening, although his ability to protrude his tongue remained unaltered. The clinical features, pathogenesis and management of submucous fibrosis are described. The widespread use of betel quid among Asians in the UK is summarized and the importance of its recognition as a precancerous condition is emphasized.

Attitudes, practices, and preferences of pediatricians regarding initiation of hepatitis B immunization at birth

OBJECTIVES

To explore practices and attitudes of pediatricians toward administration of the first dose of hepatitis B vaccine to infants, and to identify factors influencing the decision of pediatricians to initiate immunization at birth versus at 1 to 2 months of age.

METHODS

A random sample of 600 pediatricians obtained from the American Academy of Pediatrics membership database was surveyed by mail.

RESULTS

Three hundred eighty (68%) of the 563 pediatricians who were located responded to the survey. Of these 380 pediatricians, 279 provided routine immunizations to children. Of the 270 pediatricians who vaccinated children with hepatitis B vaccine and indicated their practice regarding the birth dose, 50% offered the first dose of hepatitis B vaccine at birth to all infants; the rest either offered the vaccine at birth only to infants of hepatitis B surface antigen-positive mothers and mothers whose serostatus is unknown, or did not offer the birth dose to any infants at all. Practicing in the inner city, working for a medical school or government hospital, and living in a state with universal immunization supply policies were associated with the respondent giving the birth dose. The strongest perceived barriers to giving the birth dose in the hospital were the difficulty tracking these vaccines (39%), the increased cost (27%), and the lack of reimbursement from insurance companies (26%). If a combination vaccine that includes hepatitis B; diphtheria, tetanus, pertussis (diphtheria and tetanus toxoids and acellular pertussis vaccine); and polio (inactivated poliovirus vaccine) antigens become available in the near future, then 38% of physicians who currently give the birth dose to all infants would prefer to wait until 2 months of age to initiate hepatitis B immunization.

CONCLUSIONS

Efforts to achieve high implementation of hepatitis B birth dose administration may falter once a hepatitis B-containing pentavalent combination vaccine becomes available. Programmatic efforts should ensure prevention of perinatal hepatitis B virus transmission through universal prenatal hepatitis B surface antigen screening and immunoprophylaxis of high-risk newborn infants.

Hepatitis B vaccination coverage among United States children

BACKGROUND

In 1991 the Advisory Committee on Immunization Practices recommended vaccination of all infants with three doses of hepatitis B virus vaccine (HepB) by 18 months of age as a key component of a comprehensive strategy to eliminate hepatitis B virus transmission in the United States. The American Academy of Pediatrics and the American Academy of Family Physicians published similar recommendations soon afterward.

METHODS

Data were obtained from the National Immunization Survey, a survey that began in 1994 and is conducted quarterly by the Centers for Disease Control and Prevention to estimate vaccination coverage among noninstitutionalized US children 19 to 35 months of age.

RESULTS

The 1999 National Immunization Survey data indicate that approximately 88.1% (95% confidence interval, 87.4, 88.8) of children 19 to 35 months of age had received at least three doses of HepB (HepB3). There has been a consistent increase in HepB3 coverage since 1994. However, the rate of increase has slowed in recent years and HepB3 coverage remains lower than coverage attained with three doses of diphtheria-tetanus-pertussis and Haemophilus influenzae vaccines. HepB3 coverage varied slightly by race/ethnicity and was highest among white and Asian children (89%). Coverage also varied by state; 26 states had levels of at least 90%.

CONCLUSIONS

Since the 1991 recommendations for universal hepatitis B vaccination, there has been a dramatic increase in coverage levels among children 19 to 35 months of age. However, the Childhood Immunization Initiative goal of 90% coverage has not been reached. Therefore continued efforts are needed to protect US children against this serious but preventable infection.

Hepatitis B vaccination practices in hospital newborn nurseries before and after changes in vaccination recommendations

BACKGROUND

Routine use of hepatitis B vaccine for low-risk newborns was suspended on July 7, 1999, because of concern about the potential risk of thimerosal, a mercury-containing vaccine preservative. Reinstatement of the birth dose was recommended when a thimerosal-free vaccine became available.

OBJECTIVE

To explore changes in hepatitis B vaccination practices for newborns related to the revised recommendations for low-risk infants (in this study, the terms newborn and infant are used interchangeably).

DESIGN

A telephone survey of a random sample of 1000 US hospitals.

PARTICIPANTS

Nurse managers, nursery directors, and staff nurses of the newborn nurseries.

MAIN OUTCOME MEASURES

Nursery vaccination practices before and after July 7, 1999, and the availability and use of thimerosal-free vaccine.

RESULTS

Interviews were conducted with 773 (87%) of 886 eligible hospitals. Before July 7, 1999, 78% of the hospitals reported vaccination practices that were consistent with recommendations at that time, although only 47% vaccinated all low-risk infants at birth. After July 7, 1999, almost all hospitals discontinued vaccination of low-risk infants, in accordance with the recommendation change; however, there was a 6-fold increase in the number of hospitals that were not vaccinating all high-risk infants. After the introduction of thimerosal-free vaccine, only 39% of the hospitals reported vaccinating all low-risk infants.

CONCLUSIONS

Most hospital nurseries altered their newborn hepatitis B vaccination practices consistent with changes in national recommendations. However, unintended consequences included the failure of some hospitals to continue vaccinating all high-risk infants and the delay in reintroducing vaccination for low-risk newborns after the introduction of a thimerosal-free vaccine. Assessments of the appropriateness of this country's response to the threat of thimerosal in vaccines should consider these findings.

Median lip fissures and their management

Median lip fissures are an uncommon condition and usually give rise to pain and episodes of bleeding. We report three cases of median lip fissures which were treated by surgical excision.

Oral self-mutilation by a 17-month-old child with Lesch-Nyhan syndrome

We report a 17-month-old boy who was a known case of Lesch-Nyhan syndrome and presented with self-inflicted oral ulcerations of his lips and cheeks. He had a normal complement of caries-free deciduous teeth. Initially a conservative approach was planned and a bite plate made, but as a result of poor compliance and persistent ulceration and after consultation with his parents it was decided to extract all deciduous teeth.

Intermittent mental paraesthesia in an edentulous mandible

A patient presenting with bilateral intermittent mental paraesthesia on wearing a lower denture on a very atrophic ridge was treated with an implant-retained overdenture which resolved her symptoms.

Observations on 25 patients treated with ball-retained overdentures using the Astra Tech implant system

Twenty-five adult patients with fully edentulous jaws, aged from 44 to 80 years were treated with seventy-one 3.5 mm diameter Astra Tech dental implants in the parasymphseal region. The length of these implants varied from 9 mm to 15 mm. Either two or three implants were inserted, subsequently exposed after a minimum period of 3 months, abutments and ball attachments placed. Full lower dentures incorporating gold alloy housings for ball-attachments were constructed. The average time that the implants were in situ was 4 years and 2 months, ranging from 1 year 3 months to 5 years and 7 months. Of the 71 implants placed, 67 achieved osseointegration-a success rate of 94%. The main complication was that of the ball-attachments becoming loose.

Progress toward integrating hepatitis B vaccine into routine infant immunization schedules in the United States, 1991 through 1994. Connecticut Hepatitis B Project Group

OBJECTIVE

We assessed progress toward universal infant immunization against hepatitis B, which was first recommended in November 1991.

METHODS

Multiple data sources were used to describe vaccination policies and trends in infant hepatitis B vaccine coverage.

RESULTS

As of June 1993, 51% of the 63 local, state, and territorial immunization programs recommended hepatitis B vaccination of all newborns shortly after birth. The number of first dosages of hepatitis B vaccine administered to infants in public sector clinics increased rapidly from late 1992 to 1993, and at the end of 1993 was approximately two thirds the number of first dosages of other infant antigens. In a nationwide survey of hospital nurseries 47% offered hepatitis B vaccine to all newborns. Of 3982 sampled newborns in these hospitals, 36.2% had been vaccinated before discharge. In San Francisco and Connecticut, where public health officials encouraged hospitals to offer hepatitis B vaccination, first-dose coverage at discharge was 82.3% in 1994 and 69.1% in 1993, respectively. Coverage was higher in healthier infants and lower in infants of older or better-educated mothers. Results from the National Health Interview Survey demonstrate that three-dose completion at 12 months of age increased form less than 1% of children born in 1989 to 40% of children born in the fourth quarter of 1992. Vaccination at birth increased from less than 1% of infants born in 1989 to 32% of infants born in the second half of 1993.

CONCLUSIONS

Infant hepatitis B vaccination has expanded rapidly since national recommendations were made; however, universal coverage has not been achieved.

Neurilemmoma involving the maxillary sinus: a case report

A case is reported of a neurilemmoma arising from the maxillary sinus. Its aetiology, presentation, histology and treatment are discussed.

A mandibular fracture triggering trigeminal neuralgia

The authors describe a case in which an elderly patient, who had previously been treated for trigeminal neuralgia, developed a subsequent fracture of the mandible at the site of a further trigger point. This presented difficulty in management of the case, and the necessary treatment is reviewed.

Disseminated histoplasmosis presenting with oral lesions - report of a case

A case of disseminated histoplasmosis is presented in which the initial diagnosis was made on the histology from oral lesions. The clinical and microscopical differential diagnoses are discussed. Including the present case, 12 of the 13 subjects with disseminated histoplasmosis initially diagnosed in Great Britain have given a history of residence in an area where the disease is endemic. Many years of good health may intervene between the original infection and its subsequent reactivation. A diminished cellular immune response may precipitate this reactivation but could also facilitate the possibility of exogenous reinfection. The literature is reviewed.
