Universal immunization of infants against Neisseria meningitidis: addressing the remaining unmet medical need in the prevention of meningitis and septicemia.

Effective immunization policies have markedly decreased the incidence of many lethal infectious diseases of childhood, including diphtheria, pertussis, and poliomyelitis, among others. In industrialized countries, relatively recent success in combating meningitis and sepsis has come with the implementation of universal immunization of infants against Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae. These universal immunization programs have reduced disease incidence and related deaths by more than 90%. Thus 2 out of the 3 major bacterial causes of invasive disease in children have now been controlled, leaving Neisseria meningitidis as the obvious next target. Currently, mortality attributable to invasive meningococcal disease remains at a level consistent with that of several other major vaccine-preventable infections prior to the implementation of immunization strategies. Unlike Hib and pneumococcus, US immunization policy against invasive meningococcal disease currently focuses on adolescents, a strategy that has been notably less than successful given that the highest incidence of invasive meningococcal disease occurs early in the first year of life. Development of safe and effective vaccines that broadly protect infants against disease caused by N. meningitidis is the next logical step in the effort to prevent bacterial meningitis and sepsis. Their universal use in infancy would follow a well-established and notably successful path.

The dental patient with special needs: a review of indications for treatment under general anesthesia.

General anesthesia (GA) can play an important role in the facilitation of dental treatment for individuals who present with challenging behaviors. This article presents a review of the literature discussing indications for the utilization of GA in the treatment of dental patients with special needs.

Special Care Dentistry Association consensus statement on sedation, anesthesia, and alternative techniques for people with special needs.

Many people with special needs (PSN) have difficulty having good oral health or accessing oral health services because of a disability or medical condition. The number of people with these conditions living in community settings and needing oral health services is increasing dramatically due to advances in medical care, deinstitutionalization, and changing societal values. Many of these individuals require additional supports beyond local anesthesia in order to receive dental treatment services. The purpose of this consensus statement is to focus on the decision-making process for choosing a method of treatment or a combination of methods for facilitating dental treatment for these individuals. These guidelines are intended to assist oral health professionals and other interested parties in planning and carrying out oral health treatment for PSN. Considerations for planning treatment and considerations for each of several alternative modalities are listed. Also discussed are considerations for the use of combinations of modalities and considerations for the repeated or frequent use of these modalities. Finally, the need to advocate for adequate education and reimbursement for the full range of support alternatives is addressed. The Special Care Dentistry Association (SCDA) is dedicated to improving oral health and well being of PSN. The SCDA hopes that these guidelines can help oral health professionals and other interested individuals and groups to work together to ensure that PSN can achieve a "lifetime of oral health."

The Impact of an Interprofessional Pediatric Oral Health Clerkship on Advancing Interprofessional Education Outcomes.

The aim of this study was to evaluate the effectiveness of an innovative pediatric interprofessional education clinical experience using oral-systemic health as the clinical population example for improving the self-reported interprofessional competencies of family nurse practitioner, dental, and medical students. The objectives of the interprofessional experience were for students to apply pediatric oral health assessment, identify the pediatric oral-systemic connection, and practice a team-based approach to improve oral-systemic outcomes. In spring 2015, fall 2015, and spring 2016, a total of 162 family nurse practitioner, dental, and medical students participated in this interprofessional experience at Bellevue Pediatric Outpatient Clinics together with a pediatric dental resident. Team members collaborated in reviewing the patient chart, taking the patient's medical and dental history, performing an oral assessment, applying fluoride varnish, and providing education and anticipatory guidance. The Interprofessional Collaborative Competency Attainment Survey (ICCAS) was used as a pretest and posttest to evaluate the degree to which students perceived changes in their attitudes about interprofessional competencies following the learning experience. In the results, all students had improved mean scores from pretest to posttest after the experience, and these changes were statistically significant for all students: nurse practitioner (p<0.01), dentistry (p<0.01), and medicine (p<0.001). The mean change from pretest to posttest was statistically significant for each of the six interprofessional competency domains (p<0.01). In both pediatric dental and primary care settings, the changes from pre- to posttest were significant (p<0.001). The experience was similarly effective for all groups of students in increasing their attitudes about interprofessional collaboration. These findings suggest that a clinical approach can be an effective strategy for helping health professions students develop interprofessional competence.

Implications for registry-based vaccine effectiveness studies from an evaluation of an immunization registry: a cross-sectional study.

BACKGROUND: Population-based electronic immunization registries create the possibility of using registry data to conduct vaccine effectiveness studies which could have methodological advantages over traditional observational studies. For study validity, the base population would have to be clearly defined and the immunization status of members of the population accurately recorded in the registry. We evaluated a city-wide immunization registry, focusing on its potential as a tool to study pertussis vaccine effectiveness, especially in adolescents. METHODS: We conducted two evaluations - one in sites that were active registry participants and one in sites that had implemented an electronic medical record with plans for future direct data transfer to the registry - of the ability to match patients' medical records to registry records and the accuracy of immunization records in the registry. For each site, records from current pediatric patients were chosen randomly. Data regarding pertussis-related immunizations, clinic usage, and demographic and identifying information were recorded; for 11-17-year-old subjects, information on MMR, hepatitis B, and varicella immunizations was also collected. Records were then matched, when possible, to registry records. For records with a registry match, immunization data were compared. RESULTS: Among 350 subjects from sites that were current registry users, 307 (87.7%) matched a registry record. Discrepancies in pertussis-related data were common for up-to-date status (22.6%), number of immunizations (34.7%), dates (10.2%), and formulation (34.4%). Among 442 subjects from sites that planned direct electronic transfer of immunization data to the registry, 393 (88.9%) would have matched a registry record; discrepancies occurred frequently in number of immunizations (11.9%), formulation (29.1%), manufacturer (94.4%), and lot number (95.1%.) Inability to match and immunization discrepancies were both more common in subjects who were older at their first visit to the provider site. For 11-17-year-old subjects, discrepancies were also common for MMR, hepatitis B, and varicella vaccination data. CONCLUSION: Provider records frequently could not be matched to registry records or had discrepancies in key immunization data. These issues were more common for older children and were present even with electronic data transfer. These results highlight general challenges that may face investigators wishing to use registry-based immunization data for vaccine effectiveness studies, especially in adolescents.

Providing dental care to patients with developmental disabilities. An introduction for the private practitioner.

During the past 20 to 25 years, in New York State, most individuals with developmental disabilities who had previously been housed in large institutions have been mainstreamed into community-based residences. This shift has created a need for dental services in the community. The article presented here provides information and tips to assist the general practitioner with integrating these patients into a private practice setting.

Quantitative adenovirus neutralization assays based on the secreted alkaline phosphatase reporter gene: application in epidemiologic studies and in the design of adenovector vaccines.

Replication-defective recombinant adenoviruses (rAd) are used as vectors for vaccines as well as for gene therapy. To determine type-specific antibodies to adenovirus (Ad) serotypes 2, 5, 24, 34, and 35, we developed quantitative neutralization assays using recombinant adenoviruses with the secreted alkaline phosphatase (SEAP) reporter gene. Among the standardized parameters, the concentration of infectious and noninfectious adenoviral particles used in the assay is critical for a reliable comparison of data from different studies. The usefulness of this assay was demonstrated in a pilot epidemiologic study of 40 healthy individuals. In this study, the highest prevalence of antiadenovirus antibodies was found for the Ad2 serotype (82.5%), followed by Ad5 (35%). The prevalence of antiadenovirus antibodies for the serotypes 24, 34, and 35 was low (7.5%, 2.5%, and 0%, respectively). In addition, epidemiologic parameters such as gender and age were statistically evaluated. A positive association was found between age and the presence of anti-Ad5 antibodies. The assay was also useful for evaluating the presence of antiadenovirus antibodies in the design of vaccines using a rhesus monkey model. In this animal model, it was possible to determine differential dose and time responses, and the specificity for the detection of neutralizing antibodies was assessed. The evaluation of serotype-specific neutralizing antibodies can be of both clinical and epidemiologic importance as a means of selecting the appropriate serotype adenovector(s).

Oral health findings in athletes with intellectual disabilities at the NYC Special Olympics.

This study collected data to describe the oral health in Special Olympics athletes with intellectual disabilities from New York City, using the standardized Special Olympics, Special Smiles protocol. A total of 664 self-selected athletes with intellectual disabilities were screened between 2005 and 2008. A standardized form was used for data collection. Screenings were performed using available light or flashlight, tongue depressor, and disposable mirror. Oral hygiene, reports of oral pain, untreated caries, missing and filled teeth were recorded. The majority of the athletes were 20 years of age or older (52%). Of the examined athletes, 9% reported oral pain, 8% needed urgent care, 28% had untreated caries, 60% had filled teeth, and 32% had signs of gingival disease. Mouthguards were recommended for 26% of athletes. Our findings offer an initial evaluation of the oral health of Special Olympics athletes with intellectual disabilities in New York City. Results showed high preventive and restorative oral health needs in the Special Olympics population.

Dental trauma management by New York City school nurses.

PURPOSE: The purpose of this study was to assess the knowledge and ability of school nurses in NYC to manage and properly treat traumatic dental injuries. METHODS: A survey questionnaire was sent to 160 randomly selected public schools and 40 randomly selected private schools in New York City. The questionnaire consisted of 24 multipart questions regarding background, personal experience, and knowledge of dental trauma. RESULTS: Seventy-four percent (74%) of the nurses rated their confidence in handling dental trauma in the middle range on a scale from 1 to 10. Sixty-two percent (62%) of nurses knew liquid was the optimal transportation method of an avulsed tooth; however, 52% of participants responded incorrectly that it was not appropriate to replant an avulsed permanent tooth. Ninety percent of nurses surveyed were interested in receiving further education in the management of dental trauma. CONCLUSION: This survey indicates that a gap of knowledge exists in the ability of school nurses to handle dental trauma.

A review of cerebral palsy for the oral health professional.

Individuals who have cerebral palsy (CP) face many physical challenges throughout their lifetimes in addition to societal barriers that can have an impact on quality of life. The ability to access appropriate dental care has long been an issue for people who have disabilities. Dentists should be integral members of teams of professionals involved in optimizing the health of individuals who have CP. As with all members of this interdisciplinary team, oral health care providers should have a thorough knowledge of the medical, cognitive, and rehabilitative issues associated with CP. With this knowledge the best possible health care can be provided.

Oral self-injurious behaviors in patients with developmental disabilities.

Self-injurious behaviors (SIB) in patients who have developmental disabilities is a complex disorder, and its underlying etiologies are poorly understood. SIB is a significant factor in hospitalizations, decisions to use psychotropic medications, and institutional placement for people who have developmental disabilities. Because this group often manifests oral SIB, the dentist may be the first professional called upon to evaluate a patient. Dental therapy focuses on symptomatic treatment to minimize tissue damage caused by SIB, but addressing the underlying impetus for the behavior is essential for successful treatment. Determining definitive therapeutic interventions is difficult because of the mixed bio behavioral etiologies for SIB. This complication necessitates a team approach that includes medical and behavioral specialists.

Vascular endothelial growth factor stimulates angiogenesis without improving collateral blood flow following hindlimb ischemia in rabbits.

This study was designed to test the ability of adenovirus-delivered vascular endothelial growth factor (Ad-VEGF) to stimulate angiogenesis and arteriogenesis in the rabbit hindlimb following the induction of ischemia and to evaluate the functional changes in the collateral circulation. Ten days after the surgical induction of hindlimb ischemia, either a control virus (1 x 10(9) pfu) or an adenovirus containing the gene for VEGF(165) (1 x 10(6), 1 x 10(7), 1 x 10(8), or 1 x 10(9) pfu) was administered intramuscularly into the ischemic limb. Thirty days after administration of the adenoviral vectors, skeletal muscle capillary density was assessed and angiography was performed as markers of angiogenesis and arteriogenesis, respectively. Hindlimb blood flow was directly measured and hyperemic tests were performed to evaluate the functional improvements in collateral blood flow. Animals treated with Ad-VEGF at 1 x 10(8) and 1 x 10(9) pfu showed elevated levels of circulating VEGF and dose-dependent hindlimb edema. These doses also led to a robust angiogenic response (i.e., increase in capillary density), but failed to improve collateral blood flow. Consistent with the lack of a functional response, there was no angiographic evidence of enhanced arteriogenesis with any dose of Ad-VEGF. Following the induction of hindlimb ischemia, administration of Ad-VEGF stimulated capillary sprouting (i.e., angiogenesis), but did not increase the growth and development of larger conduit vessels (i.e., arteriogenesis) or improve collateral blood flow. These results support the concept that VEGF may not be expected to have therapeutic utility for the treatment of peripheral or myocardial ischemia.
