Maternal morbid obesity: financial implications of weight management.

The objective of this study was to evaluate health outcomes and costs of pregnancies complicated by extreme maternal obesity (class III obesity, body mass index ≥ 40). We conducted a retrospective case-control descriptive study comparing extremely obese women (cases) and their infants with randomly selected controls. Health outcomes were obtained from the medical records and costs from billing data. Total costs for each mother-infant dyad were calculated. Compared with 85 controls, the 82 cases experienced higher morbidity, higher costs and prolonged hospital stay. However, 26% of cases maintained or lost weight during pregnancy, whereas none of the controls maintained or lost weight during pregnancy. When mother/infant dyads were compared on costs, case subjects who maintained or lost weight experienced lower costs than those who gained weight. Neonatal intensive care consumed 78% of total hospital costs for infants of the obese women who gained weight, but only 48% of costs for infants of obese women who maintained or lost weight. For extremely obese women, weight management during pregnancy was achievable, resulted in healthier neonatal outcomes and reduced perinatal healthcare costs.

Spirituality and HIV disease: an integrated perspective.

Spirituality is an important resource that individuals use to cope with a chronic illness such as HIV disease. Spirituality has both a religious and an existential component that share the concepts of meaning in life, hope, self-transcendence, and rituals. An integrated perspective utilizing these shared concepts is proposed to assist HIV-positive individuals in coping with the challenges of their disease. Nursing interventions include promoting hope, teaching, sharing information, and creating a sense of empowerment in people with HIV to address spiritual issues. The article concludes with a case study that emphasizes application of the integrated perspective of spirituality with an HIV-positive person.

Association of early bilateral middle ear effusion with language at age 5 years.

OBJECTIVE: This study tested the hypothesis that children with early persistent middle ear effusion (MEE) are at risk for later language deficit. METHOD: We recruited 698 newborns and monitored them for MEE every 2 to 4 weeks at home until age 3 years. Language skills were assessed on 294 subjects at age 5, while controlling for 8 demographic and environmental factors. Language outcomes at age 5 years were studied as a function of duration of bilateral MEE from birth to age 3 years. RESULTS: A significant relation was found between duration of bilateral MEE and speech sound sensitivity (Carrow Elicited Language Inventory) and articulation (Goldman-Fristoe Articulation). Children's ability to discriminate speech sounds in a quiet environment (Carrow Auditory Visual Abilities Test) was less affected by early prolonged MEE in homes that provided more cognitive stimulation. CONCLUSIONS: These exploratory results indicate that prolonged early MEE may predispose children to language deficits at age 5 years. The language deficits are of small magnitude and may or may not be clinically significant. Language stimulation at home may protect against some of the effects of prolonged MEE.

A single intramuscular dose of ceftriaxone changes nasopharyngeal bacterial flora in children with acute otitis media.

The increasing prevalence of drug-resistant bacteria is attributed to the extensive use of antibiotics, which causes selective pressure on the nasopharyngeal bacterial flora. Shortened courses of antibiotics have been proposed to decrease the development of resistant strains. We determined the effect of a single intramuscular dose of ceftriaxone (50 mg/kg) on the nasopharyngeal bacterial flora in 167 children (median age 13 mo) with acute otitis media. Nasopharyngeal samples for bacterial culture were obtained before and 5 d after treatment with ceftriaxone. Before treatment, Moraxella catarrhalis was isolated in 99 (59%) children, Streptococcus pneumoniae in 87 (52%), and Haemophilus influenzae in 53 (32%). After treatment, M. catarrhalis was found in 62 (37%) children, which constitutes a 37% decrease in the colonization rate by this pathogen (p < 0.001). S. pneumoniae was isolated in 50 (30%; 43% decrease) and H. influenzae in 17 (10%; 68% decrease) children after treatment (p < 0.001 for both). Before treatment, 60% of pneumococcal isolates were sensitive to penicillin, 26% were of intermediate susceptibility, and 14% were penicillin-resistant. Eradication of S. pneumoniae occurred mainly in children with penicillin-sensitive isolates. As a consequence, only 24% of pneumococcal isolates that remained after treatment were sensitive to penicillin, 59% were penicillin-intermediate, and 16% were penicillin-resistant. A single dose of ceftriaxone resulted in significant changes in the nasopharyngeal bacterial flora, increasing the relative prevalence of pneumococcal strains with decreased susceptibility to penicillin.

Effects of early middle ear effusion on child intelligence at three, five, and seven years of age.

OBJECTIVE: This study tested the hypothesis that children with prolonged middle ear effusion (MEE) during the first 3 years of life are at risk for cognitive delays or deficits. METHOD: A prospective study enrolled 698 children from diverse backgrounds and controlled for eight demographic and environmental factors. Participants were recruited at birth and monitored for ear status frequently in the home; 379 children were assessed for cognition with the Stanford-Binet, 4th ed., at 3 years of age, 294 at 5 years, and 198 at 7 years. RESULTS: Using the SAS General Linear Models (GLM) procedure, we found a significant direct relation between duration of bilateral MEE and Stanford-Binet Composite and Nonverbal Reasoning/Visualization Factor scores at age 3, but not at age 5 or age 7. Statistical clustering analysis revealed four groups with different temporal patterns of MEE: Low MEE, Early MEE (peaking at 0-6 months), Later MEE (peaking at 6-12 months), and High MEE. GLM analyses revealed no direct effects, but several moderated effects, of MEE cluster on cognitive development at 3 years, but none at 5 or 7 years. In general, children in the Later MEE and High MEE groups appeared to be more adversely affected by bilateral MEE at 3 years, but effects were moderated in complex ways by socioeconomic status or home stimulation. Growth curve modeling across the three assessment periods showed no effects of total duration of MEE but did indicate that children in the Later MEE cluster had low scores at age 3 but caught up at ages 5 and 7. CONCLUSIONS: Prolonged MEE, especially between 6 and 12 months, may put children at risk for cognitive delays at 3 years, but the risk effect is not strong and effects are no longer detectable at 5 or 7 years.

Lead screening among low-income children in Galveston, Texas.

The objective of this study was to report results of a lead-screening program for low-income children living in Galveston, Texas. We obtained blood lead by graphite furnace spectrophotometry on 1,571 children aged 6 months to 8 years. Nineteen percent of children had blood lead levels > or = 10 mcg/dL. Risk factors included African-American ethnicity, young age, and residence in old housing. Follow-up was accomplished in only 50% of children with low-level toxicity. Lead screening is an important public health measure in communities with old houses. For screening to be successful, caregivers need to devote additional effort to follow-up.

A double-blind, placebo-controlled trial of decongestant-antihistamine for the treatment of sinusitis in children.

We studied the effectiveness of nasal decongestant-antihistamine in treating acute sinusitis in children. All subjects received oral amoxicillin for 14 days. Subjects randomized to the decongestant-antihistamine group received nasal oxymetazolone and oral syrup containing brompheniramine and phenylpropanolamine. Controls received placebo nasal saline and oral syrup. In both groups symptoms resolved quickly, and radiographs improved significantly. Responses to treatment were similar between the two groups. Water's radiographs of the maxillary sinuses proved reliable in the assessment of the degree of sinus involvement. We conclude that decongestant-antihistamine need not be given to the child with acute maxillary sinusitis.

An asthma self-management program for children, including instruction in peak flow monitoring by school nurses.

A randomized trial of an instructional method was conducted in which school nurses taught children asthma self-management principles and skills, including peak flow monitoring, in 20-min, individual sessions over an 8-week period. Thirty-six children participated. An intervention group of 18 children received the teaching sessions. A control group of 18 children received regular care by the nurses, but no teaching sessions. The sample included 64% boys, 69% African-Americans, and 69% Medicaid recipients. The average age of subjects was 10.2 years. The two groups were demographically similar, but despite random assignment, the control group had a significantly earlier age of onset of asthma and tended to have had more asthma attacks in the preceding year. These factors were statistically controlled in outcome analyses. Results of group comparisons showed no significant differences in the number of postintervention emergency room visits and days absent from school. However, nurses reported that children who practiced breathing exercises had less anxiety during exacerbations, and the nurses' knowledge of the children's baseline peak expiratory flow rates facilitated care of the children. Nurses expressed the opinion that the individual sessions with students might be useful in motivating them to participate effectively in later group sessions. The intervention was well accepted by students, parents, and nurses. We believe that this intervention is promising as a practical, low-cost approach to enhancing children's asthma self-management skills and warrants further testing in a larger sample, with the intervention conducted over a longer period.

Meeting the faculty development needs of generalist physicians in academia.

Development of the academic environments of generalist faculty members is essential if they are to develop the skills to become leaders in medical education and primary care research and effective role models for their students. We conducted a needs assessment that included two-thirds of the generalist faculty members in family medicine, internal medicine, and pediatrics at the University of Texas Medical Branch, Galveston, Texas. The assessment was based on open-ended discussions in small focus groups and on responses to an informal checklist of 24 potential faculty development goals. The participants identified three global needs requiring significant change: (1) better understanding of and rewards for their academic activities, (2) better networking with each other and with nongeneralists, and (3) more control over their time and responsibilities. Individual needs for academic development were diverse but emphasized teaching and career-building skills. Meeting the individual needs of generalist academicians depends on addressing environmental obstacles to their academic development. We recommend building project-oriented teams that collectively develop skills in strategic planning and project management, political negotiation and public relations, and creative use of institutional support systems. Individual faculty development can then be linked to the development of high-priority group projects that stimulate learning and allow opportunities to practice new skills.

Use of videotaping to evaluate pediatric resident performance of health supervision examinations of infants.

STUDY OBJECTIVES: To demonstrate reliability of a method for evaluating pediatric resident performance of health supervision examinations of infants using real patients and to evaluate pediatric resident performance of health supervision examinations of infants before and after an educational intervention consisting of a 6-month ambulatory rotation combined with video-assisted review of resident performance of the examination. DESIGN: Longitudinal cohort study in which all second-year residents were enrolled. Residents' preintervention (baseline) videotapes were compared with postintervention videotapes. Each resident served as his or her own control. SETTING: University hospital pediatric resident continuity clinic. SUBJECTS: Sixteen second-year pediatric residents who were participating in a required 6-month ambulatory rotation. METHOD AND MAIN RESULTS: Reliability study: Using a 51-item instrument derived from the American Academy of Pediatrics Guidelines for Health Supervision, trained raters blind to the sequence and dates of the videotaped health supervision examinations independently rated 44 resident encounters (a minimum of two raters per tape) and achieved good interrater reliability (kappa = 0.80). Intervention study: After a 6-month ambulatory rotation which included resident-faculty reviews of preintervention videotapes, residents showed a 14% mean improvement in performance scores for the examination (P < .05). CONCLUSIONS: The results indicate that videotaped health supervision examinations using real patients can be reliably evaluated by observational techniques in a continuity practice. A 6-month ambulatory block rotation coupled with video-assisted interactive review of examinations is associated with measurable improvement in resident performance on the postintervention test.

Bone mineral density of the lumbar vertebrae in children and adolescents with insulin-dependent diabetes mellitus.

To test the hypothesis that bone mineral density (BMD) is lower in children with insulin-dependent diabetes mellitus (IDDM), we measured BMD of the lumbar vertebrae (L-2 to L-4) by dual-photon absorptiometry in 31 boys and 25 girls, mean age 12.3 years, with IDDM of varying clinical duration (range 0.1 to 14.8 years). Mean standard deviation scores (z scores) were determined for L-2-L-4 BMD, weight, height, weight percentile, and weight-adjusted L-2-L-4 BMD index (L-2-L-4 BMD/weight), with reference data from a previously described white, nondiabetic, age-matched control group (n = 221). Compared with nondiabetic control subjects, male patients with short-term IDDM and all female patients with IDDM did not have significantly different L-2-L-4 BMD, weight, weight percentile, height, or BMD index. Boys with IDDM longer than 1 year had significantly lower weight, weight percentile, and height than did age-matched control subjects. When L-2-L-4 BMD of boys with long-term diabetes was corrected for weight, the L-2-L-4 BMD index was significantly greater than that of control subjects, indicating that weight was disproportionately lower than BMD. There were no significant linear correlations between metabolic control and L-2-L-4 BMD. When L-2-L-4 BMD was adjusted for differences in body weight, spinal BMD values in children with IDDM were not lower than in control subjects. These findings indicate that in children with IDDM, as in previously studied nondiabetic youths, body weight and spinal BMD are highly correlated; although BMD is reduced in some children with diabetes, the reduction parallels reductions in growth, and may simply reflect a normal response of the skeleton to a lower weight-bearing load.

Health and safety in day care: parental knowledge.

Because injuries and illnesses occur among children, even in licensed child care facilities, parents need to be aware of existing hazards. We developed a questionnaire to assess parental knowledge of 16 health and safety features in their child's care facility. These health and safety features were identified by parents, in a pilot study, as being the most important features in a child care facility. This questionnaire was completed by 91 parents who use day care. Parents were well-educated employees of a health care institution. Our results indicate that even well-educated parents often do not check child care facilities for health and safety features. Parents tolerated a mean of 9.3% of 16 unsafe features and did not know the status of 22.4% of the features. Fifteen percent of the children has been removed from their child care facility because of health and safety concerns, 7.7% reported an injury. Our results suggest that it is important that physicians, during well child visits, include discussions about health and safety issues in the day care environment.

Spinal bone mineral density in 335 normal and obese children and adolescents: evidence for ethnic and sex differences.

Spinal bone mineral density (BMD) and anthropometric measures were studied in 312 nonobese and 23 obese black, white and Hispanic children and adolescents age 5.00-18.99 years. In adolescents BMD correlated with age, weight, height, fat-free density, body mass index, and midarm circumference. Utilizing the entire group of 312 nonobese subjects, mean Z scores were calculated for comparison versus reference subgroups for bone mineral density index (BMDI, BMD/weight). BMDI was greater for black than for white and Hispanic children and adolescents across all ages studied. Female adolescents accumulated spinal mineral more rapidly than male adolescents. Black males had greater mineral than white and Hispanic males. Differences in BMDI between subgroups could not be explained by differences in body weight or spinal vertebral size. BMDI proved a more sensitive measure for comparing subgroups than did BMD. The study provides normative data and a quantitative methodology for analyzing differences in spinal mineral between groups of children and adolescents.

School health training during pediatric residency.

Pediatricians are becoming increasingly concerned about reaching beyond the office or clinic to help solve problems of child and family health. The physician's ability to interact with school personnel and communities is one important approach to this outreach effort. School health training has been a required 6-month component of the pediatric residency curriculum at the University of Texas Medical Branch, Galveston, since 1979, with second-year residents providing weekly on-site consultations to public school districts and participating in a weekly school health seminar series. In this study, graduates from this program were surveyed to determine their evaluations of the training and extent of current school involvement and to use their evaluations for curriculum evaluation. Residents who participated in the school consultation from 1979 through 1988 were surveyed. Seventy-eight pediatricians responded, a 79% return rate. Ratings by the graduates reveal that both pediatric generalists and subspecialists highly value their training experiences. Ratings were not related to the specific site to which the resident consultant had been assigned. Of these pediatricians, 41% are currently consulting with school personnel. These findings are discussed as they relate to other reports of physician involvement in schools and provide clues to curriculum design for school health training in pediatric residency.

Injury and illness surveillance at local Special Olympic Games.

The purposes of this study were to: determine the incidence of injury and illness among Special Olympic athletes at local competitions; assess the relative risk of medical problems among Down's syndrome athletes; and compare the relative risk of sports injury incurred by athletes participating in various Special Olympic events. Health stations were set up at all sports venues and injury/illness surveillance records were kept for all injury/illness encounters during a 3-day competition for 777 Special Olympic athletes. A total of 3.5% of the athletes required injury/illness care during the games. Down's syndrome athletes were 3.2 times as likely to encounter a medical problem. Track and field events provided the least activity time and the most injuries. These data suggest that Special Olympic games at the local level are safe and that planners should prepare to treat more illnesses than injuries at such competitions.
