Reverse Maryland bridges: clinical applications.

The "Maryland Bridge" or the etched metal-composite bonded retainer has experienced a variety of clinical applications since its inception as the etched enamel plastic-bonded Rochette periodontal splint. Through the evolutionary stages of different metals and framework preparation for composite bonding by electrolytic, chemical, and air-abrasive procedures and the improvements in bonding composites, the bridge has been in clinical use for approximately 9 to 10 years. Certain clinical and radiographic criteria must be satisfied prior to using the conventional Maryland bridge, but with the unique application of the basic bridge design modified and placed from the labial or buccal position some previously contraindicated uses of the bridge can be reversed by using a unique, if not provocative, application of the bridge design principles. This article presents two clinical case reports utilizing the Maryland bridge applied from the labial and buccal aspect. Both fixed partial dentures presented have been in place clinically for over 18 months, whereas others of this type have been successfully in place for over 6 years.

Impact of on-site social work services on the documentation of client and family-centered information: the experience of Ryan White CARE Act (Title IV) pediatric program sites in Maryland.

BACKGROUND: The purpose of this study is to (1) describe client and maternal demographic, social, and medical characteristics of pediatric clients receiving medical and social services at Ryan White (Title IV) program sites, and (2) determine the impact of on-site social work services in documenting client and family-related information used to assess the psychosocial needs of the families affected by human immunodeficiency syndrome and acquired immunodeficiency syndrome (HIV/AIDS). METHODS: We studied infants born to known HIV-infected women who received HIV-related medical services at a federally funded Title IV Ryan White CARE Act provider site in Maryland. Eligibility criteria included < 24 months of age at time of initial clinic visit, a history of birth to a known HIV-infected woman, and a minimum of one comprehensive clinical visit for medical evaluation at a selected Title IV provider site. Study populations were categorized into three independent clinic cohorts. A pre- and postintervention study design was used to assess the impact of the intervention (i.e., on-site social work activities) on variables of interest. Clinic cohorts were (a) preintervention group (N = 181), from January 1, 1986 to December 31, 1989; (b) initial postintervention group (N = 216), from January 1, 1991 to December 31, 1992; and, (c) long-term postintervention group (N = 197), from January 1, 1993 to March 1, 1994. Client and maternal demographic, social, and medical information were recorded and statistical comparisons between pre- and postintervention clinic cohorts were completed with the use of standard statistical methods. RESULTS: Pediatric clients were predominantly African American (94%), lived in low-income family units reflected by the prevalence of public assistance programs (i.e., Medicaid), had a high likelihood of Medicaid enrollment (> 80%), and reported a high frequency of social disruption (e.g., protective services interventions and housing difficulties). Greater than half of all medical records documented the "mother" as the client's primary caregiver in the three cohorts (a,b,c, above) pre- and postintervention cohorts, 51%, 65%, and 66.5%, respectively. Over two-thirds of the mothers among all cohorts were reported to have a current or past history of illicit drug use or alcohol abuse, 69%, 62%, and 67.5%, respectively. Postintervention groups, both initial and long term, were significantly more likely than the preintervention group to have documented medical record information relevant to a history of protective services, housing problems, and maternal demographic, social, and clinical information. Maternal HIV-related clinical status and select social factors (e.g., drug use, housing) remained underreported in both postintervention groups. CONCLUSIONS: Title IV pediatric clinical sites deliver services to a predominantly urban, poor, minority community-the population at greatest risk for pediatric HIV-infection in Maryland. Alternative family members as the primary caregiver for infants and children was common and increased over time. These findings demonstrate that Title IV funded programs have been successful in the documentation of valuable client and maternal information necessary for the development of family-centered clinical and support services to a highly vulnerable population of HIV at-risk or infected infants and children in Maryland.

Technology's role in addressing Maryland's nursing shortage.

Maryland, as other states in the United States, has experienced a nursing shortage. It is thought that the use of technology could help alleviate this shortage. A volunteer group has worked for over four years to identify technology solutions to ease the shortage of nurses. Two projects were undertaken--a grassroots survey of technology solutions to meet Maryland nurses' top concerns and a research study. The results of both the informal and formal study will be presented.

Kawasaki syndrome. A case-control study during an outbreak in Maryland.

An outbreak of 30 cases of Kawasaki syndrome (KS) occurred in Maryland from January through May 1983. The mean age of patients was 27 months; 60% were male. Rug shampoo exposure within one month and within six months of illness was not significantly greater in the 30 epidemic and seven sporadic cases than in their neighborhood and pediatric controls. These findings suggest that rug shampoo exposure may not be an important risk factor in the outbreak of KS in Maryland.

Enhanced surveillance for pregnancy-associated mortality--Maryland, 1993-1998.

CONTEXT: Deaths occurring among women who are pregnant or who have had a recent pregnancy have a devastating impact on the family and community. It is important to understand the magnitude and causes of pregnancy-associated mortality so that comprehensive strategies can be formulated to prevent such deaths. OBJECTIVE: To ascertain the number and causes of pregnancy-associated deaths using enhanced surveillance techniques. DESIGN, SETTING, AND SUBJECTS: Retrospective, cross-sectional analysis of death certificate data of reproductive-age women, live birth and fetal death records, and medical examiner records in Maryland during 1993-1998. MAIN OUTCOME MEASURE: Number of pregnancy-associated deaths, defined as death from any cause during pregnancy or within 1 year of delivery or pregnancy termination, by source of data and cause of death. RESULTS: A total of 247 pregnancy-associated deaths were ascertained. Twenty-seven percent (n = 67) were identified through cause-of-death information obtained from death certificates, 70% (n = 174) through linkage of death records with birth and fetal death records, and 47% (n = 116) through review of medical examiner records. Homicide was the leading cause of pregnancy-associated death (n = 50; 20%), and cardiovascular disorders were the second-leading cause (n = 48; 19%). CONCLUSIONS: In this Maryland sample, comprehensive identification of pregnancy-associated deaths was accomplished only after collecting information from multiple sources and including all deaths occurring up to 1 year after delivery or pregnancy termination. This enhanced pregnancy mortality surveillance led to the disturbing finding that a pregnant or recently pregnant woman is more likely to be a victim of homicide than to die of any other cause. By broadening pregnancy mortality to include all possible causes, previously neglected factors may assume increased importance in prenatal and postpartum care.

A survey of size-specific mercury concentrations in game fish from Maryland fresh and estuarine waters.

A survey of size-specific mercury (Hg) concentrations in game fish from a subset of Maryland fresh and estuarine waters was conducted, in which Hg concentrations in 112 fish from seven freshwater impoundments and three tidal and four estuarine locations in Chesapeake Bay and its tributaries were measured. Striped bass (Morone saxatilis) was the most intensively examined species. Of the fish examined, the largest freshwater sportfish contained the highest Hg concentrations. Striped bass and largemouth bass (Micropterus salmoides) from Chesapeake Bay and its tributaries contained less Hg at the same size than the same species in fresh waters. Large striped bass, chain pickerel (Esox niger), and walleye (Stizostedion vitreum) from Deep Creek Lake and Liberty Reservoir exceeded the FDA action level of 1 mg Hg/kg. Striped bass, largemouth bass, and white crappie (Pomoxis annularis) in other impoundments equaled or exceeded a common advisory level of 0.5 mg Hg/kg. Large differences in size-normalized Hg concentrations among lakes and particularly between fresh and salt waters highlight the large differences in MeHg production and bioaccumulation among ecosystems. This work indicates that a more comprehensive study of Hg in Maryland fish is warranted to protect human and wildlife health.

Survey of practicing cardiologists in Maryland on their choice of thrombolytic therapy for acute myocardial infarction.

In November 1990, we surveyed 160 practicing community cardiologists in the state of Maryland and 20 academic cardiologists at the University of Maryland Medical Center to determine each individual's preference for aggressive versus nonaggressive therapy for various presentations of acute myocardial infarction. The survey was repeated in April 1991 following a report of the results of the Third International Study of Infarct Survival. All 100 responding cardiologists chose aggressive therapy to manage an early (less than 2 hours) acute anterior myocardial infarction in a 50-year-old patient. However, less aggressive therapy was chosen by many community cardiologists for management of early inferior acute myocardial infarction or for elderly patients. Most community cardiologists chose tissue plasminogen activator as their thrombolytic drug of choice, whereas university cardiologists favored streptokinase. Although there were substantial shifts in choice of thrombolytic agent on the repeat survey, most community physicians still chose tissue plasminogen activator over the less expensive streptokinase.

Assessment of infection control programs in Maryland skilled-nursing long-term care facilities.

BACKGROUND: Nosocomial infections cause substantial morbidity and mortality among residents in long-term care facilities (LTCFs). Although infection control programs now exist in many LTCFs in the United States, little has been published regarding the effectiveness of these programs. The 1976 Centers for Disease Control and Prevention Study on the Efficacy of Nosocomial Infection Control (SENIC) established the effectiveness of infection control programs in acute care facilities. However, a limitation of that study was the exclusion of LTCFs. METHODS: The purpose of this pilot study was to assess infection control programs in LTCFs through the use of an Infection Surveillance and Control Questionnaire adapted from SENIC. The sample consisted of 123 skilled-nursing LTCFs in the State of Maryland. The questionnaire was completed by the person responsible for infection control activities in each LTCF. RESULTS: Results of the study show the following: (1) an upward trend in infection control activity in Maryland LTCFs, with the majority having medium activity, and (2) an estimated overall prevalence rate of infection of 4% on the basis of total resident census. CONCLUSION: The findings indicated that the Infection Surveillance and Control Questionnaire is a reliable instrument to assess infection control programs in LTCFs. A nationwide study is planned to examine the relationship between infection control activity and the risk of nosocomial infection among skilled-nursing LTCFs throughout the United States.

Case-fatality rates by body part affected and trends in hospitalized burns in Maryland, 1981-90.

This study was undertaken (i) to determine in-hospital case-fatality rates (CFRs) by severity using body part(s) affected as a proxy, and (ii) to examine the trends in hospitalized burns regarding CFRs. The study used the Health Service Cost Review Commission non-confidential Maryland hospital discharge data for the years 1981-90. CFRs were computed as percentages of hospitalized burns that died. Chi-square tests were used to assess homogeneity for categorical variables and to examine linear trends. The CFR for hospitalized burns was 2.9 per cent. CFR was highest among the elderly (13.1 per cent) and for burns affecting multiple specified sites (7.4 per cent), and lowest among children (1.1 per cent) and for upper limb burns (0.22 per cent). Burn CFR increased overall by 59 per cent for 1981-90, with a decreasing rate only in children. However, after controlling for age and degree of burn no significant change in trend in CFRs over the 10-year period was evident. The findings demonstrate that while child burn fatality seems to have declined, the elderly continue to have high CFR for burns regardless of the body part affected, and that the CFRs for hospitalized burns remained constant between 1981 and 1990 in Maryland despite considerable advances in treatment.

Fluoxetine and violent death in Maryland.

A retrospective Medical Examiner case review of all deaths in Maryland where either fluoxetine or tricyclic antidepressant (TCA) use was forensically detected was conducted for the time period January 1987-July 1991. Case records and toxicology reports from the Office of the Chief Medical Examiner were reviewed to determine cause and manner of death, circumstances of death, demographic information on the decedent, prior medical history of the decedent, and presence and level of either fluoxetine or TCA in various body fluids/tissues. Suicide was the manner of death most frequently associated with TCA and fluoxetine detection. Violent methods were more often associated with fluoxetine suicides than with TCA suicides (65% v. 23%, P < 0.001). Demographic characteristics of antidepressant-related deaths in Maryland were similar to those of the entire USA. Possible explanations for the results obtained include the inherent lower lethality of fluoxetine compared to the TCAs, necessitating the use of additional means to complete the act of suicide; that physicians may have switched more impulsive, high risk patients to this new agent as it became available, thus creating a selection bias for more violence-prone individuals in the fluoxetine group; or that fluoxetine may be associated with induction of violence and/or suicidal ideation. Further research examining the possible association of these agents with violent acts is warranted.

Investigation of sudden infant deaths in the State of Maryland (1990-2000).

The Office of the Chief Medical Examiner (OCME) has recorded a significant decline in the deaths of sudden infant death syndrome (SIDS) in the state of Maryland since 1994. However, infants who died of accidental or non-accidental injuries remained consistent during the same time period. This report focuses on the epidemiological characteristics and scene investigation findings of infant victims who died suddenly and unexpectedly in Maryland between 1990 and 2000. A retrospective study of OCME cases between 1990 and 2000 yielded a total of 1619 infant fatalities. 802 infant deaths were determined to be SIDS, which represented 50% of the total infant deaths in our study population. Five hundred and twenty-three (31.8%) deaths were due to natural diseases, 128 (7.9%) deaths were accidents, and 74 (4.6%) were homicides. The manner of death could not be determined after a thorough scene investigation, review of history and a complete postmortem examination in 92 (5.7%) infants. SIDS deaths most often involved infants who were male and black. The peak incidence of SIDS was between 2 and 4 months of age. The majority of SIDS infants (60%) were found unresponsive on their stomach. Among SIDS infants, 269 (33.4%) were found in bed with another person or persons (bed sharing). Of the bed-sharing SIDS cases, 182 (68%) were African-American. In the past 11 years, 52 infants died of asphyxia due to unsafe sleeping environment, such as defective cribs, ill-fitting mattresses, inappropriate bedding materials. Of the 74 homicide victims, 53 (70%) involved infants less than 6 months of age. Twenty (27%) exhibited the classical abuse syndrome characterized by repeated acts of trauma to the infants.

Breakfast and lunch meal skipping patterns among fourth-grade children from selected public schools in urban, suburban, and rural maryland.

The objective of this study was to describe breakfast and lunch consumption patterns of fourth-grade students from selected public schools in Maryland and how they differ by geographic location. Data were collected from a sample of 540 fourth-grade public school children (46% male, 62% white; mean age=9 years) from three geographically distinct regions of Maryland (30% rural, 30% suburban, and 40% urban). Data on breakfast and lunch consumption were collected using an in-classroom questionnaire. chi(2) tests were used to compare skipping meal behavior by geographic location. Twenty percent of fourth-grade students reported skipping breakfast and/or lunch at least three times per week. Urban students were more than twice as likely to skip breakfast and to eat school-prepared meals compared with suburban and rural students. Dietitians in all regions need to explore new ways to encourage regular meal consumption among students in their schools.

Discrepancies in body image perception among fourth-grade public school children from urban, suburban, and rural Maryland.

OBJECTIVE: The objective of this study was to determine whether there is an association between body image perception and weight status as measured by the body mass index among a group of fourth graders in Maryland. DESIGN: Cross-sectional data on height, weight, and body image were collected in the classroom. At risk for being overweight and being overweight designations were assigned to participants with body mass index (BMI) percentile values for age and sex of >/=85 to <95 and BMI >/=95, respectively. Students selected a figure (range 1 to 7) to represent their current and ideal images. SUBJECTS: The subjects of this study were 524 fourth-grade public school students (54% girls; 61% white; mean age, 9.2 years) from three geographically distinct regions in Maryland (38.6% urban, 30.7% suburban, 30.7% rural). Statistical analyses chi(2) tests were used to compare weight status with sex, race, geographic location, and body image discrepancy categories. One-way analysis of variance was used to compare BMI and body image scores with sex and race/ethnicity to geographic location. RESULTS: Thirteen percent of students were overweight, and 15% were at risk of overweight. There was no association between weight status and race, body image perception, or geographic location. African Americans chose larger figures than whites and other races to represent their current and ideal images and were most satisfied with their body size. CONCLUSIONS: Perceptions of body image are formed early in life. Dietitians can provide guidance on appropriate weight and body size to children, parents, and school professionals. Dietitians can also use their influence to secure funding for nutrition education programs.

Parathyroidectomy in Maryland: effects of an endocrine center.

BACKGROUND: Surgery for hyperparathyroidism is associated with high cure rates and low morbidity and mortality when performed by experienced surgeons. We wanted to determine whether referral of patients with hyperparathyroidism to an endocrine surgery center has an impact on patient outcomes and costs. METHODS: Data from 901 patients who underwent parathyroidectomy recorded in the Maryland inpatient discharge database between 1990 and 1994 at 52 hospitals were compared with 169 consecutive patients who underwent surgical exploration by one surgeon (R.U.) at the Johns Hopkins Hospital. RESULTS: Although in 47 of 52 hospitals fewer than 10 parathyroidectomies were performed each year, in these hospitals four of five related deaths occurred before patient discharge. The percentage of parathyroidectomies in Maryland performed by one endocrine surgeon has increased from 8% in 1990 to 21% in 1994 and is associated with a 97% cure rate and no mortality. Moreover, while hospital length of stay (LOS) in the state has decreased from 7 to 3.1 days, LOS for the high-volume provider has declined to a mean of 1.3 days. CONCLUSIONS: Patients with hyperparathyroidism are increasingly referred to an endocrine surgery center, which results in a high cure rate, low morbidity, no mortality, and a shorter LOS. Improved surgical outcomes and lower costs depend on an experienced surgeon and argue for the referral of these patients to endocrine surgery centers.

Epidemiologic analysis of existing data to investigate hypertensive renal disease: an example from the Maryland End-Stage Renal Disease Registry.

Observational epidemiology provides powerful methods for studying the etiology and natural history of renal disease in populations. Existing data sets can be used in the conduct of cross-sectional, case-control, and cohort studies that complement experimental investigations. Analysis of existing data sets is extremely efficient and, in many instances, provides results of similar quality to those derived from studies that depend on the collection of original data. A study based on linkage of hypertensive end-stage renal disease (ESRD) incidence rates from the Maryland Regional ESRD Registry with corresponding prevalence data from a state-wide survey of cardiovascular risk factors (The Maryland Statewide Household Hypertension Survey) illustrates the power, efficiency, and flexibility of observational epidemiologic methods in investigating racial differences in hypertensive ESRD. Such analyses can both test previously established hypotheses and generate new hypotheses for subsequent investigation.

Maryland family physicians' knowledge, opinions and practices about oral cancer.

The objective of this study was to assess family physicians' knowledge, opinions and practices regarding oral cancers in the state of Maryland, USA. A 40-item, self-administered questionnaire was mailed to all members of the Maryland Academy of Family Physicians. Unweighted data (n=240) were analyzed using SAS and SUDAAN software; results were evaluated using an alpha < or =0.05. Family physicians (FPs) were aware of the major risk factors for oral cancers, but misinformation existed about the non-risk factors. Approximately 77% asked their patients the eight questions related to risk factors for oral cancer when taking a medical history but less than 24% provided an oral cancer examination to patients 40 years of age and over. Nearly 64% were interested in a continuing education course about oral cancer. This survey identified gaps in knowledge and practices among FPs but it is encouraging that they expressed interest in continuing education courses on this topic.

Carotenoid, tocopherol, phenolic acid, and antioxidant properties of Maryland-grown soft wheat.

Consumers' desires to either reduce the risk of or manage a specific health condition through improved diet have stimulated the research of agricultural products for their potential health beneficial components such as tocopherols and natural antioxidants. Soft wheat is one of the major crops in Maryland, with little information available about its potentially beneficial components. This study examined eight selected Maryland-grown soft wheat varieties or experimental lines for their potential beneficial components including tocopherols, carotenoids, total phenolics and phenolic acids and their antioxidant properties, including Fe(2+) chelating capacity and free radical scavenging activities against 2,2-diphenyl-1-picrylhydrazyl radical (DPPH(*) ), radical cation ABTS(*)(+), and oxygen radical (ORAC). The results showed that all tested soft wheat grain samples contained alpha-tocopherol, with a range of 3.4-10.1 microg/g. Lutein was the primary carotenoid present in the grain samples at a level of 0.82-1.14 microg/g, along with significant amounts of zeaxanthin and beta-carotene. Vanillic, syringic, p-coumaric, and ferulic acids were found in soluble free, soluble conjugated, and insoluble bound forms in the grain extracts, with ferulic acid as the predominant phenolic acid. The eight soft wheat varieties differed in their antioxidant properties. The tested wheat grain samples exhibited ED(50) values against DPPH(*) of 23-27 mg of grain equiv/mL, ORAC of 32.9-48 micromol of Trolox equiv (TE)/g, and ABTS(*)(+) scavenging capacity of 14.3-17.6 micromol of TE/g. These data suggest the possibility of producing soft wheat varieties rich in selected health beneficial factors for optimum human nutrition though breeding programs.

Using environmental stressor information to predict the ecological status of Maryland non-tidal streams as measured by biological indicators.

In Maryland. U.S., an interim framework has recently been developed for using biologically based thresholds, or 'biocriteria', to assess the health of nontidal streams statewide at watershed scales. The evaluation of impairment is based on indices of biological integrity from the Maryland Biological Stream Survey (MBSS). We applied logistic regression to quantify how the biotic integrity of streams at a local scale is affected by cumulative effects resulting from catchment land uses, point sources, and nearby transmission line rights-of-way. Indicators for land use were developed from the remote sensing National Land Cover Data and applied at different scales. We determined that the risk of local impairment in nontidal streams rapidly increases with increased urban land use in the catchment area. The average likelihood of failing biocriteria doubled with every 10% points increment in urban land, thus an increase in urban land use from 0 to 20% quadruples the risk of impairment. For the basins evaluated in this study, catchments with more than 40-50% urban land use had greater than 80% probability of failing biocriteria, on average. Inclusion of rights-of-way and point sources in the model did not significantly improve the fit for this data set, most likely because of their low numbers. The overall results indicate that our predictive modeling approach can help pinpoint stream ecosystems experiencing or vulnerable to degradation.
