A population-based study of the 22q11.2 deletion: phenotype, incidence, and contribution to major birth defects in the population.

OBJECTIVES: Although several studies describe the 22q11.2 deletion, population-based data are scant. Such data are needed to evaluate properly the impact, distribution, and clinical presentation of the deletion in the population. Our goals were to assess the population-based birth prevalence of the 22q11.2 deletion and its associated phenotype and its impact on the occurrence of heart defects. METHODS: We evaluated data on infants who were born from 1994 through 1999 to women who resided in metropolitan Atlanta. We matched records from the Metropolitan Atlanta Congenital Defects Program (a population-based registry with active case ascertainment), the Sibley Heart Center at Children's Healthcare of Atlanta, and the Division of Medical Genetics at Emory University. We used birth certificate data for the denominators of the rates. RESULTS: We identified 43 children with laboratory-confirmed 22q11.2 deletion among 255 849 births. The overall prevalence was 1 in 5950 births (95% confidence interval: 1 in 4417 to 1 in 8224 births). The prevalence was between 1 in 6000 and 1 in 6500 among whites, blacks, and Asians and 1 in 3800 among Hispanics. Most affected children (81%) had a heart defect, and many (1 in 3) had major extracardiac defects (other than velopalatal anomalies), including anomalies of the central nervous system. Overall, the deletion contributed to at least 1 of every 68 cases of major heart defects identified in the total birth cohort and, in particular, to 1 of every 2 cases diagnosed with interrupted aortic arch type B, 1 of every 5 with truncus arteriosus, and 1 of every 8 with tetralogy of Fallot. CONCLUSIONS: The 22q11.2 deletion was common in this birth population. The clinical phenotype included a wide and variable spectrum of major cardiac and extracardiac anomalies. From these population-based data, one can estimate that at least 700 affected infants are born annually in the United States. Population-based estimates such as these should be useful to medical professionals and policy makers in planning for the optimal care of people with the 22q11.2 deletion.

Evaluation of an oral disease control program administered to a clinic population at a suburban dental school.

This study included 99 patients. Seventy-four of these participated in the Oral Disease Control program at Emory University School of Dentistry and 25 control patients did not. Those who completed the Oral Disease Control program were examined and scored from 2 to 24 months afterward. The Patient Hygiene Performance Scoring was used. It was found that there was no significant difference in levels of plaque between subjects who completed the Oral Disease Program and those who did not participate. Also, the patient's knowledge of the causes of dental caries and gingival disease bore no significant relationship to the amount of plaque present. Further, certain selected hygiene habits had no significant effect on plaque level. The patients studied were enthusiastic about the control program and developed an increased awareness of oral disease control. However, this study confirms others that demonstrate the need for repeated professional reinforcement in any effective oral disease control program.

Osseo-integrated implant treatment of a patient with rapidly progressive periodontitis. A case report.

The case report presented describes placement of osseointegrated fixtures in a patient with a probable history of rapidly progressive periodontitis. A 12-year history is presented. The post-operative sequelae of placing fixtures in a fully edentulous maxilla and partially edentulous mandible were the worst seen by the Implant Team at Emory University. The hypothesis presented is that patients with aggressive forms of periodontal disease should be subjected to appropriate mechanical and antimicrobial therapy to produce a healthy oral flora before any implants are placed.

Comparing the predictive accuracy of health risk appraisal: the Centers for Disease Control versus Carter Center program.

BACKGROUND: From 1986 to 1987 the Carter Center of Emory University joined with the Centers for Disease Control (CDC) to develop a new, probability-based, adult health risk appraisal (HRA) instrument for the public domain. This new instrument is compared with the CDC HRA version to determine which is a more accurate predictor of mortality. METHODS: We compared predicted mortality risks from the CDC HRA and the Carter Center HRA with the observed mortality among 3135 smokers and never-smoking persons, aged 25 to 60, followed from 1959 to 1979 as part of the Tecumseh Community Health Study. RESULTS: When individuals were classified according to the difference between their actual age and risk age, for the CDC HRA, there was a progressively increasing risk of 10-year mortality as the difference increased. The Carter Center HRA did not show this trend. An analysis using relative operating characteristic curves showed that the mortality risk predictions for both programs were very similar for men and women. However, differences between actual age and risk age for the two programs were not similar for men or women, particularly older men. Therefore, actual age minus risk age for the CDC program was a more accurate predictor of 10-year mortality than was this difference for the Carter Center program. CONCLUSIONS: The results from both types of analyses suggest that the validity of risk ages obtained from the Carter Center version may not be sufficient to justify updating programs for those currently using the CDC instrument.

Gas in the pancreatic bed without abscess.

A series of 259 patients from the Emory University Affiliated Hospitals with clinical suspicion of pancreatic inflammatory or neoplastic disease was reviewed. Seven of the patients had documented gas in a pancreatic mass; three of the cases were proved subsequently not to be pancreatic abscess formation. Two of the seven patients had proven fistulae from pseudocyst to bowel documented either by surgery or on an associated radiologic examination which accounted for the gas. In one additional patient, no fistula was identified at preoperative radiologic examination or at surgery. The awareness of this entity is important in the avoidance of unnecessary surgery. Since patients with spontaneous cystoenteric fistulae improve after rupture into the gastrointestinal tract, this entity should be kept in mind, particularly in the patient who is not toxic. Radiologic evaluation of the gastrointestinal tract to detect fistulous communication, percutaneous aspiration, and culture may prevent unnecessary surgery.

The use of ketorolac in the management of postoperative pain.

Ketorolac tromethamine (Toradol) is a nonsteroidal antiinflammatory drug (NSAID) available in intramuscular (IM) and oral formulations for the management of acute pain. Intramuscular ketorolac is the only parenteral NSAID available for analgesic use in the US. The clinical profile is reviewed, and clinical studies most applicable to a postoperative patient are discussed in detail. The results of a clinical study performed at Emory University School of Medicine are presented. In this single-dose study, 176 patients received either 10 mg of oral ketorolac, 5 mg or 10 mg of IM morphine, or placebo after orthopedic surgery. The analgesic efficacy of ketorolac was comparable to both doses of morphine and significantly superior to placebo. Ketorolac, when administered intramuscularly or orally, is a safe and effective analgesic agent for the short-term management of acute postoperative pain and can be used as an alternative to opioid therapy.

Buying a healthcare information system.

Replacing an antiquated computer system with state of the art equipment and software is a lengthy, at times frustrating, and never an easy decision. At Wesley Woods Center on Aging, Atlanta, an integrated provider of healthcare for the elderly affiliated with Emory University, the process consumed more than two and a half years. This article takes the reader through the entire process, from the initial decision to replace an existing system, through the final purchase and installation. It looks candidly at the problems that were encountered, including turnover among key personnel, difficulties with involving all of the user groups, changes in the technology and coordination with the University. The lessons Wesley Woods learned in its experience can be of benefit to any healthcare facility contemplating an information system change.

Improving patient care through problem-solving groups.

In a competitive healthcare environment where as much attention must be given to quality of care as to cost containment, hospitals must learn to involve their lowest-paid paraprofessionals in decision making, since often these people have as much or more contact with patients than do physicians and nurses. One effective employee-involvement technique is the problem-solving group (PSG), which works to identify, analyze, choose, and implement solutions to various problems that influence the quality of patient care. A PSG project involving a typical paraprofessional unit was begun in spring 1985 at Emory University Hospital, Atlanta. The project's developmental stages were the following: Gathering data; Identifying problems; Providing feedback; Selecting PSG members; Focusing on problems; Generating solutions; Choosing the best solution; Implementing solutions; Managing successful outcomes. The PSG project was successful in addressing almost all the 15 identified problems in the department. Involving the staff in the PSG project resulted in higher morale, greater satisfaction with management, and a more favorable attitude toward their jobs.

The role of the primary care PA.

At a time when roles of various allied health care providers frequently overlap, it is important to clearly delineate who does what, so there is less provider and patient confusion. In the case of the PA, it is also advantageous to determine periodically whether there are new functions to the role previously not described in the literature. The roles of primary care PAs were validated by using a mail survey developed through a review of PA roles frequently mentioned in the literature. The survey was sent to 47 training programs and 222 Emory University PA graduates working in primary care and non-primary care practices. Mean and median scores for each role per respondent category are reported and compared with mean differences between groups about role perceptions. Strong agreement occurred between and among respondent groups for PA roles dealing with documentation of health status, analysis of data, formulation and conduction of treatment and/or management plan, management of life-threatening emergencies, and patient education. From these data, competencies, performance criteria, and objectives can be generated for each validated role to assist in creating a competency-based curriculum for PAs.

The telemedicine and second medical opinion.

Telemedicine is declared as delivery of care to patients anywhere in the world by combining communications technology, with medical expertise. The well established applications of telemedicine are in the field of teleradiology, pathology, cardiology. In some cases video-conferencing (VC) may be applied. Second medical opinion is an important additional viewpoint on the patient diagnosis and treatment. The established network of consultant hospitals and worldwide Second opinion centers enable a fast (24-72 hours response) second medical opinion consultation service with the telemedicine application. The consultant hospitals at present time are: UCSF--San Franscisco, Stanford Medical Center, Bowman Gray School of Medicine, The Brigham Radiology Foundation, Emory University Hospital, University of Pennsylvania Medical Center. The second opinion centers are located worldwide, just to mention some of them: London, Budapest, Ljubljana, Tel Aviv, Bombay, Athens, Milano, Seoul.

Angiographic and clinical follow-up of percutaneous revascularization for transplant coronary artery disease.

BACKGROUND: There are limited data on the use of percutaneous revascularization techniques for transplant coronary artery disease (CAD). METHODS: Medical records and angiographic results for cardiac transplant patients undergoing percutaneous revascularization at Emory University Hospital were reviewed. Procedural results, results of angiography 4Eth 6 months after intervention, and clinical follow-up were recorded. RESULTS: Nineteen patients underwent 51 interventions. Thirty-eight lesions (75%) were de novo and 13 (25%) were restenotic. All patients had hypertension, 37% had diabetes, 79% had elevated lipid levels, and 53% had at least one episode of moderate to severe allograft rejection (grade 3A or greater). The primary procedural success rate was 100% with no major complications. Six-month restenosis rate (defined as > 50%) was 49%. At 23+/-17 months follow-up, 6 patients were dead or retransplanted (31%). Thirteen patients were alive without retransplantation (9 New York Heart Association class I, 3 class II, 1 class III). CONCLUSION: Percutaneous revascularization is safe and has a high initial procedural success rate in patients with transplant CAD. However, the restenosis rate in this population remains higher than reported for atherosclerotic coronary disease and the long-term prognosis remains poor.

Echocardiographic validation of gated SPECT ventricular function measurements.

UNLABELLED: Left ventricular (LV) volumes are valuable prognostic indicators in the management of coronary artery disease and traditionally have been obtained by x-ray contrast angiography or echocardiography. There now are several scintigraphic methods to compute volumes that are based on different LV modeling assumptions. Both the reasons that calculations from different nuclear techniques can disagree with one another and the relationship of these values to the more conventional echocardiographic measurements must be investigated thoroughly for calculations to be interpretable for individual patients. METHODS: Echocardiographic volumes were determined in 33 retrospective subjects with coronary artery disease (mean age, 61 +/- 12 y; 42% men; 70% with abnormal perfusion and 58% with abnormal segmental wall motion) using the modified Simpson's rule technique applied to digitized apical 4-chamber and apical 2-chamber views of 4 averaged heartbeats. These volumes were compared with those from 3 gated SPECT methods based on Simpson's rule LV modeling similar to standard echocardiographic algorithms (SPECT EF from St. Luke's-Roosevelt Hospital) (method 1), Gaussian myocardial count profile curve fitting (QGS from Cedars-Sinai Medical Center) (method 2), and an endocardial model based on perfusion sampling and count-based thickening (Cardiac Toolbox from Emory University) (method 3). RESULTS: By ANOVA, there were no significant differences among ejection fractions (EFs), but there were for volumes. Paired t test analysis showed volumes from methods 2 and 3 to be significantly larger than echocardiographic volumes and larger than those of method 1. Linear regression analysis comparing gated SPECT and echocardiographic volumes showed a nearly identical strong correlation (r = 0.92; P < 0.000001) for all 3 methods. Excellent correlation also was found among gated SPECT volumes from the 3 methods (r = 0.94). Bland-Altman analysis and t tests showed that method 1 volumes (70 +/- 61 mL) were the same as for echocardiography (77 +/- 55 mL), but volumes were overestimated by method 2 (105 +/- 74 mL) and method 3 (127 +/- 92 mL), particularly for larger volumes. Pearson coefficients for EFs compared with echocardiography were r = 0.82, 0.75, and 0.72 for methods 1-3, respectively. EFs correlated strongly among the 3 gated SPECT methods (r = 0.86-0.92). The Fisher z test showed no differences among these methods for any of the volume or EF linear correlation analyses. CONCLUSION: All gated SPECT parameters correlated well with echocardiographic values. However, the gated SPECT method for which underlying assumptions most closely resembled those commonly used in echocardiography produced mean volume values closest in agreement with echocardiographic measurements.

Surgical management of malignant melanoma using dynamic lymphoscintigraphy and gamma probe-guided sentinel lymph node biopsy: the Emory experience.

Sentinel lymph node (SLN) biopsy is revolutionizing the surgical management of primary malignant melanoma. It allows accurate nodal staging which targets patients who may benefit from regional lymphadenectomy and systemic therapy. This is a retrospective review of patients treated at Emory University for stage I and II malignant melanoma with gamma probe-guided SLN biopsy from 1/1/94 to 6/30/98. Three hundred sixty patients (males 228, females 132) were identified. Primary melanoma sites included: head and neck 58, trunk 148, and extremities 154 (upper 71, lower 83). Primary tumor staging was T1 9, T2 134, T3 153, and T4 64. SLNs were successfully identified in 99.7 per cent of patients and 98.9 per cent of nodal basins mapped. In 275 (76.6%) cases a single draining nodal basin was identified. In 84 (23.3%) cases there were multiple draining nodal basins. Positive SLNs were identified in 63 patients (17.5%). SLN positivity by tumor staging was T1 0 per cent, T2 9.0 per cent, T3 22.2 per cent, and T4 26.6 per cent. The overall recurrence rate was 11.9 per cent. Recurrences by SLN status were SLN+, 27 per cent, and SLN-, 8.8 per cent. Regional recurrence occurred in 7 (2.4%) of the 297 with negative SLN biopsies and 7 (11.1%) of the 63 with positive SLN biopsies. Dynamic lymphoscintigraphy and gamma probe-guided SLN localization was successful in more than 98 per cent of cases. Patients with negative SLN biopsies have a low risk of recurrence.

Early and Intermediate Outcomes After Rotational Atherectomy in Octogenarian Patients.

OBJECTIVE: To provide information about the use of rotational atherectomy in octogenarians. MATERIAL AND METHODS: From 1993-1996, 26 octogenarians underwent coronary intervention with rotablator at Emory University Hospitals. The total number of lesions were 28 (57% of them in the left artery descending). Adjunctive balloon angioplasty was utilized in 26 lesions. The lesions were eccentric in 82%, calcified in 75%, with a mean length of 10.2Â+/-8.5 mm. RESULTS: The angiographic success rate was 96.2%. The only in-hospital complications was the death of 1 patient (3.8%) after an abrupt closure, and a dissection of 1 lesion of another patient, with a favorable subsequent outcome. The mean follow up was 1.3Â+/-0.4 years. The Kaplan-Meier survival rate at 1 year was 96.2% and at 2 years 78.3%. The freedom from death, myocardial infarction (MI), and coronary artery bypass graft (CABG) was 88.5% at 1 year and 59.7 % at 1.5 and 2 years. The freedom from death, MI, CABG, and percutaneous transluminal coronary angioplasty (PTCA) was 69.2% at one year and 36.3% at 1.5 and 2 years. CONCLUSIONS: In octogenarians with complex lesions, rotablator was performed in conjunction with balloon angioplasty, and showed a high rate of angiographic success, a relatively low complication rate, and a favorable 2 years survival rate. Nevertheless, the event free rates did not show the same favorable evolution after 1 year. If feasible, it would be useful to conduct randomized trials in the elderly to compare interventional procedures to medical treatment or surgery. (c)1999 by CVRR, Inc.

Assessment of an audio-visual feedback device used in motor training,.

A miniature biofeedback device, the Basmajian-Emory Muscle Trainer, has been developed at the Emory University School of Medicine. A training and testing protocol was designed for using this device in the training of precise voluntary control of individual skeletal muscles. Thirteen normal subjects were trained to abduct the big toe of the right foot, eleven of whom displayed increases in maximum motion. Use of a biofeedback device to improve a subject's ROM capabilities requires consideration of four factors: (1) initial emphasis must be on making the subject aware of his muscle activity, (2) the muscle activity must be increased, (3) the positive re-enforcement of feedback must be continual, and (4) the newly acquired muscle activity must be used to perform a greattting.

DAPD (Emory University/Triangle Pharmaceuticals/Abbott Laboratories).

Triangle Pharmaceuticals is developing DAPD, a prodrug of the viral replication inhibitor dioxolane guanosine, as a potential therapy for HIV and HBV infection. Phase I/II dose range studies have commenced for HIV, and clinical development for HBV was to have commenced by late 1999 [319145], [319956]. Phase II trials are scheduled for the second quarter of 2001. The FDA has designated DAPD as a Fast Track product [365894]. DAPD is from a different nucleoside series to FTC and CS-92, which are also in development by Triangle. The compound may offer advantages over several nucleosides from other series that are already on the market because of its unique structure and pharmacological properties [247083]. Both DAPD and DXG are dioxolane purine nucleoside analogs [319660]. Preclinical data suggest DAPD may be of use in combination therapies for HIV-infected patients who are therapy-naive, in addition to patients who have previously received treatment and including those infected with drug-resistant strains of HIV-1 [341145], [341335]. Triangle licensed DAPD from Emory University [216900]. In June 1999, Triangle and Abbott Laboratories entered into an alliance for the development and marketing of six antiviral products, including DAPD [326824].
