Abstract
Life care planning is a method of assessing future care needs and associated costs for the lifetime of individuals who have experienced catastrophic injury or have chronic health care needs. The culmination of the life care planning process is a document known as the Life Care Plan. Social workers, especially medical social workers, because of their education and health-related experience are excellent candidates for becoming Life Care Planners upon meeting certification requirements. This article describes life care planning and how social workers can enter this field.

Abstract
Using genotypes of 280 marker loci on the 22 autosomes of 105 alcohol-dependent probands, their affected and unaffected sibs, as well as their parents, we iteratively constructed a genetic similarity function that enabled us to quantify the interindividual genetic distances d(x(i), xj) between feature vectors x(i), xj made up by the allelic patterns of individuals i, j with respect to loci l1, l2,...,ln. Based on this similarity function, we investigated the sib-sib similarities that are expected to deviate from "0.5" in affected sib pairs if the region of interest contains markers close to disease-causing genes. The reference value "0.5" was derived from the parents-offspring similarities, because these are independent of the affection status. The question of population admixture was addressed by means of multivariate structural analyses. These analyses led to four "natural" groups whose validity was tested through the father-mother similarities. Additionally, we determined the eigenvectors that optimally represented the genetic variation and found several marker configurations on chromosomes 1, 3, 7, 15, and 17 that reproducibly discriminated (p < or = 0.01) affected probands/sibs from unaffected sibs, while no such differences were found between affected probands and affected sibs.

Abstract
The availability of low molecular weight heparin (LMWH), with associated ease of home delivery and enhanced efficacy and safety, has rendered the long-term outpatient use of LMWH feasible. Although warfarin is usually used for long-term secondary prevention, it is not the drug of choice for a variety of conditions such as antiphospholipid thrombosis syndrome, sticky platelet syndrome, and patients with malignancy and other medical conditions who have failed adequate warfarin doses. We assessed the long-term efficacy and safety of outpatient dalteparin in a series of patients with conditions associated with prior warfarin failure or potential to warfarin therapy (antiphospholipid syndrome). The results of this study, detailed herein, demonstrate that long-term dalteparin is highly effective and safe when used as long-term therapy for secondary prevention in selected prothrombotic disorders.

Abstract
To gain insight into the routes of presentation of pathogen sequences via DNA vaccines, we have compared the abilities of sequences encoding fragment C of tetanus toxin (FrC) and influenza A virus nucleoprotein (NP) to induce antibody or cytotoxic T-cell (CTL) responses in vivo. Strong antibody and CTL responses were induced against FrC targeted to the endoplasmic reticulum (ER) and both were reduced by removal of the leader sequence. In contrast, targeting of NP to the ER generated only a modest antibody response, likely due to misfolding in this site. Removal of the leader sequence led to anti-NP antibodies via cross-priming. For NP, induction of CTLs was not influenced by the leader sequence. Exogenous FrC or NP delivered as proteins were unable to induce CTLs. Routes to induction of optimal immune responses via DNA evidently differ according to the nature of the encoded pathogen sequence. Understanding processing pathways for pathogen sequences should assist rational design of DNA vaccines.

Abstract
DNA vaccines against cancer have to activate an inadequate or damaged immune system in order to attack residual cancer cells. Although the potential problem of tolerance may be overcome by transplantation, provision of high levels of T-cell help is likely to be an important factor in stimulating effective immune pathways. The fusion gene approach appears to provide the required help, and offers a rational design for raising both antibody and T-cell mediated attack against lymphoma and myeloma, which express idiotypic antigen at the cell surface or as a secreted protein respectively. Intriguingly, preliminary data indicate that the fusion gene approach promotes antibody responses against a different cell surface tumour antigen, CEA. Strategies for using DNA vaccines to induce attack on processed peptides bound to MHC class I molecules are also being developed. We hope and anticipate that all categories of tumour antigen may be susceptible to this powerful new technology. The critical clinical requirement, however, will be to treat the presenting tumour with maintenance or restoration of immune capacity. We await results of the preliminary clinical trials with great interest.

Abstract
Collection of sensitive data with the use of video-enhanced, computer-assisted, self-administered interviews (V-CASI) has the potential to reduce interview bias and improve the validity of the study. The purpose of this study was to compare responses to sensitive questions elicited by V-CASI and by face-to-face interview (FTFI) methods. Women attending a New Orleans, Louisiana, public family planning or sexually transmitted disease clinic from July 1995 to July 1996, diagnosed with a Chlamydia trachomatis infection responded to eight close-ended behavioral questions (four socially undesirable, two socially desirable, and two neutral behaviors) using both FTFI and V-CASI techniques in a randomized crossover design. Of the 280 women included, the mean age was 23 years, 95 percent were African American, and 71 percent felt comfortable using computers. While kappa scores indicated good-to-excellent agreement between interview techniques, women tended to admit to socially undesirable behaviors more often on V-CASI compared with FTFI. Thirty percent of the women gave a discrepant response between V-CASI and FTFI toward social desirability. Women who reported a socially undesirable behavior in V-CASI (i.e., more than two sex partners and infrequent condom usage) were more likely to have a discrepant response. Utilization of the same logistic regression model to predict condom use yielded different results when data from V-CASI were used compared with data from FTFI. The V-CASI technique can reduce social desirability bias and improve validity in research requiring information on sensitive sexual behaviors.

Abstract
Kapandji pinning has been proposed as the treatment of choice for unstable Colles' fractures. The aim of this paper is to evaluate our experience treating unstable Colles' type fractures using this technique. Over a nine month period, 36 patients with Colles' type fractures were treated operatively at St. Vincent's Hospital. 22 of these fractures were deemed unstable and were treated using percutaneous intrafocal Kapandji pinning. 20 of these patients were recalled for review at a mean of 11.3 month post injury. At this stage the wrist was examined clinically and radiologically. Initial satisfactory correction of deformity was achieved by this technique. Between the time of wire removal and final review, however, there was significant recurrence of dorsal angulation (P < 0.05), but no significant radial shortening on radiographs. The patients had a satisfactory clinical result in spite of these radiological parameters.

Abstract
Ca2+ transients measured in failing human ventricular myocytes exhibit reduced amplitude, slowed relaxation, and blunted frequency dependence. In the companion article (O'Rourke B, Kass DA, Tomaselli GF, Kääb S, Tunin R, Marbán E. Mechanisms of altered excitation-contraction coupling in canine tachycardia-induced heart, I: experimental studies. Circ Res. 1999;84:562-570), O'Rourke et al show that Ca2+ transients recorded in myocytes isolated from canine hearts subjected to the tachycardia pacing protocol exhibit similar responses. Analyses of protein levels in these failing hearts reveal that both SR Ca2+ ATPase and phospholamban are decreased on average by 28% and that Na+/Ca2+ exchanger (NCX) protein is increased on average by 104%. In this article, we present a model of the canine midmyocardial ventricular action potential and Ca2+ transient. The model is used to estimate the degree of functional upregulation and downregulation of NCX and SR Ca2+ ATPase in heart failure using data obtained from 2 different experimental protocols. Model estimates of average SR Ca2+ ATPase functional downregulation obtained using these experimental protocols are 49% and 62%. Model estimates of average NCX functional upregulation range are 38% and 75%. Simulation of voltage-clamp Ca2+ transients indicates that such changes are sufficient to account for the reduced amplitude, altered shape, and slowed relaxation of Ca2+ transients in the failing canine heart. Model analyses also suggest that altered expression of Ca2+ handling proteins plays a significant role in prolongation of action potential duration in failing canine myocytes.

Abstract
BACKGROUND AND OBJECTIVES Differences in sociodemographic attributes and healthcare access may explain differences in regional sexually transmitted disease rates but don't fully explain why syphilis persists disproportionately in certain populations. GOAL OF THIS STUDY To understand the behavioral epidemiology of syphilis, we conducted a social network analysis of persons with syphilis and their contacts and developed and applied a definition of core transmitters. STUDY DESIGN We interviewed 10 index persons with primary or secondary untreated syphilis and 80 of their named sexual and social contacts. RESULTS Fourteen (16%) of 90 interviewed persons met the definition of core transmitters, 9 of whom had past or current syphilis. The other interviewed persons had only moderately risky behaviors. Seventy-eight (42%) of the network sexual contacts were connected directly or indirectly to a core transmitter. CONCLUSION This analysis suggests that syphilis transmission is maintained by a community with a small percentage of high-risk persons centrally placed amidst a larger group with moderately risky behavior.

Abstract
OBJECTIVES This article describes the implementation and impact of the first statewide condom social marketing intervention in the United States. METHODS A statewide social marketing program made condoms freely available in 93 public health clinics, 39 community mental health centers, 29 substance abuse treatment sites, and more than 1000 businesses in neighborhoods with high rates of sexually transmitted diseases (STDs) and HIV. Surveys about condom use were conducted annually. RESULTS Between 1994 and 1996, more than 33 million condoms were distributed without significant opposition. Over time, self-reported condom use at the last sexual encounter increased among African American women (from 28% in 1994 to 36% in 1996), particularly African American women with 2 or more sex partners (from 30% to 48%). Condom use at the last sexual encounter increased among African American men (from 40% in 1994 to an average of 54% in 1996). The number of reported sex partners did not increase. CONCLUSIONS Condom social marketing can be successfully implemented in the United States. The widespread availability of free condoms is associated with increased condom use, particularly among persons at high risk for STDs and HIV.

Abstract
Our results with concurrent biochemotherapy in patients with stage IV melanoma have been encouraging. Based on these data, we conducted a phase II study to determine the clinical and histological response rate to neoadjuvant concurrent biochemotherapy in patients with local-regional metastases of cutaneous melanoma (stage III). A total of 65 patients with biopsy-proven, measurable and potentially resectable local-regional disease (nodal, satellite/in-transit metastases and/or local recurrence) were treated with cisplatin 20 mg/m2 intravenously (i.v.) on days 1 to 4, vinblastine 1.5 mg/m2 i.v. on days 1 to 4, dacarbazine 800 mg/m2 i.v. on day 1 only, interleukin-2 9 MIU/m2 per day i.v. by 96 h continuous infusion on days 1 to 4, and interferon-alpha 2a 5 MU/m2 subcutaneously on days 1 to 5, repeated every 3 weeks. Patients underwent surgery after two to four courses of biochemotherapy. Those with tumour regression after two preoperative courses received two additional postoperative courses. Of the 64 patients assessable for clinical response, 28 (44%) had a partial response. Of the 62 patients whose response was assessed histologically, four (6.5%) had no evidence of viable tumour in the surgical specimen (pathological complete remission, pCR) and 27 (43.5%) had a partial response, giving an overall response rate of 50%. Tumour burden did not correlate with response, although patients who achieved a pCR had a significantly lower tumour burden (P = 0.02). Our phase II study indicates that neoadjuvant biochemotherapy is an active treatment for melanoma patients with local-regional metastases. However, it is unclear if biochemotherapy is more active than chemotherapy alone; phase III randomized trials are ongoing to answer this question in patients with stage IV disease.

Abstract
Influenza A is associated with leukopenia, although it is not reported to cause isolated thrombocytopenia, anemia, or pancytopenia. The authors report three pediatric patients with transient cytopenias associated with influenza A infection, all of whom had evidence for influenza A infection by direct immunofluorescence from nasopharyngeal aspirates. In all patients, cytopenias were transient and improved as their viral symptoms resolved. All patients improved spontaneously. This is the first report of transient pancytopenia, anemia, or thrombocytopenia associated with influenza A infection. Given the high frequency of influenza A infections during the winter months, it is important to recognize the associated hematologic findings.

Abstract
Clinical studies have shown that second-generation femoral cementing techniques at total hip replacement result in a superior fixation of the femoral stem. In an effort to determine what benefits further developments in cementing techniques would provide, we compared the morphology of the cement mantles produced by traditional finger-packing and gun-insertion techniques. The porosity of the cement mantles was quantified using computerised image analysis. The finger-packing technique caused large air inclusions that resulted in large pores in the substance of the cement mantle, whereas the cement-gun technique did not result in any individual pore with an equivalent diameter greater than 3 mm. The mean porosity of cement mantles prepared using the finger-insertion technique was 8.3%, whereas the mean porosity in gun-prepared mantles was 1.7%. The use of a cement gun significantly reduced the porosity of femoral cement mantles (P = 0.02). Reduction of defects in the substance of the cement mantle may account for the increased survival of femoral prostheses inserted when second-generation techniques were used. Further reduction of the porosity of the cement mantle could not be expected to produce as dramatic a clinical improvement in prosthesis fixation.

Abstract
There is substantial evidence for a significant genetic component to the risk for alcoholism. In searching for genes that contribute to this risk, the diagnostic criteria for alcohol dependence may not be the optimal phenotype; rather, creation of a more homogeneous phenotype will lead to a more homogeneous genetic etiology. Items from the Semi-Structured Assessment for the Genetics of Alcoholism collected from 830 individuals in 105 alcoholic families were used in a latent class analysis to identify a more homogeneous alcoholism-related phenotype. A four-class solution was chosen: class 1, unaffected group; class 2, mildly problematic group; class 3, moderately affected group; and class 4, severely affected group. Classes 3 and 4 had higher symptom endorsement probabilities than classes 1 and 2 for items reflecting severe alcohol dependence, and were combined to provide enough sibling pairs for genetic linkage analysis. A total of 291 markers distributed throughout the genome, with an average intermarker distance of 14 cM, were genotyped. Linkage analysis was performed to detect loci underlying classes 3 and 4, the moderately and severely affected alcoholics, of whom 88% met the Collaborative Study of the Genetics of Alcoholism, and >99% met ICD-10 criteria for alcohol dependence. Evidence for a locus on chromosome 16, near the marker D16S675, was found with a maximum multipoint lod score of 4.0. Analysis of additional markers on chromosome 16 yielded a lod score of 3.2, narrowed the critical region, and placed the gene between D16S475 and D16S675 in a 15 cM interval.

Abstract
Vaccination with idiotypic protein protects against B-cell lymphoma, mainly through anti-idiotypic antibody. For use in patients, DNA vaccines containing single-chain Fv derived from tumor provide a convenient alternative vaccine delivery system. However, single-chain Fv sequence alone induces low anti-idiotypic response and poor protection against lymphoma. Fusion of the gene encoding fragment C of tetanus toxin to single-chain Fv substantially promotes the anti-idiotypic response and induces strong protection against B-cell lymphoma. The same fusion design also induces protective immunity against a surface Ig-negative myeloma. These findings indicate that fusion to a pathogen sequence allows a tumor antigen to engage diverse immune mechanisms that suppress growth. This fusion design has the added advantage of overcoming potential tolerance to tumor that may exist in patients.

Abstract
Recent data collected at six identical electrophysiological laboratories from the large national multisite Collaborative Study on the Genetics of Alcoholism provide evidence for considering the P3 amplitude of the event-related potential as a phenotypic marker for the risk of alcoholism. The distribution of P3 amplitude to target stimuli at the Pz electrode in individuals 16 years of age and over from 163 randomly ascertained control families (n = 687) was compared with those from 219 densely affected alcoholic families (n = 1276) in which three directly interviewed first-degree relatives met both DSM-III-R and Feighner criteria at the definite level for alcohol dependence (stage II). The control sample did not exclude individuals with psychiatric illness or alcoholism to obtain incidence rates of psychiatric disorders similar to those of the general population. P3 amplitude data from control families was converted to Z-scores, and a P3 amplitude beyond 2 SD's below the mean was considered an "abnormal trait." When age- and sex-matched distributions of P3 amplitude were compared, members of densely affected stage II families were more likely to manifest low P3 amplitudes (2 SD below the mean) than members of control families, comparing affected and unaffected offspring, and all individuals; all comparisons of these distributions between groups were significant (p < 0.00001). P3 amplitude means were also significantly lower in stage II family members, compared with control family members for all comparisons, namely probands, affected and unaffected individuals (p < 0.0001), and offspring (p < 0.01). Furthermore, affected individuals from stage II families, but not control families, had significantly lower P3 amplitudes than unaffected individuals (p < 0.001). Affected males from stage II families had significantly lower P3 amplitudes than affected females (p < 0.001). Recent linkage analyses indicate that visual P3 amplitude provides a biological phenotypic marker that has genetic underpinnings.

Abstract
OBJECTIVE To determine the contributions of psychological trauma (exposure to combat during the Vietnam War), genetic factors, childhood experiences shared by twin siblings, and unmeasured experiences not shared by twin siblings to the reporting of current physical health problems a mean of 19 years after military service. METHODS In 1987, a national sample of 2224 monozygotic and 1818 dizygotic male veteran members of the Vietnam Era Twin Registry participated in a survey of health. Genetic modeling was performed on cross-sectional physical health and combat exposure data derived from Registry twins. RESULTS Combat experiences explained a small proportion (0.7-8.4%) of the variance in the report of hypertension, respiratory conditions, persistent skin conditions, gastrointestinal disorders, joint disorders, and hearing problems. Childhood experiences shared by siblings are not clearly related to any health problem studied. By contrast, genetic factors explain 31 to 54% and noncombat experiences not shared by siblings explain 45 to 66% of the variance in current physical health status. CONCLUSIONS Greater than 90% of the variance in reported current physical health problems in Vietnam era veterans is attributable to inherited factors and unmeasured environmental experiences not shared by twin siblings. The traumatic experience of combat makes only a small contribution to the report of current physical health problems. These results do not preclude the possibility that combat influenced the prevalence of illness shortly after military service or that combat may influence the development of illness in the future.

Abstract
BACKGROUND Parent-of-origin effect (POE) is suggested in transmission of bipolar disorder. Bipolar II disorder (BPII) should be considered separately. METHODS The gender difference of transmitting parents, prevalence rate in children, and age at onset of patients in relation to the sex of the transmitting parent, were examined in 220 BPII patients. RESULTS No evidence suggesting involvement of POE was found. CONCLUSION POE is not involved in transmission of BPII. LIMITATION Number of subjects is not sufficient. Rate of interviewed subjects differs between mothers and fathers. CLINICAL RELEVANCE Female BPII patients do not transmit the disease more often than male patients.

Abstract
We treated 20 women with locally advanced breast cancer between January 1991 and September 1996. The treatment regimen included 4 cycles of intensive doxorubicin (30 mg/m2/d on 3 consecutive days every 2 weeks with G-CSF support), followed by appropriate surgery, followed by high dose therapy with cyclophosphamide, carboplatin and thiotepa (STAMP V, CTCb). Of the 20 patients, seven presented with inflammatory breast cancer, three with Stage IIIB, seven with stage IIIA, one with multifocal Stage IIB and two with Stage IV M1 (ipsilateral supraclavicular lymph node involvement) (including one who had an inflammatory primary) disease. Six patients had not undergone mastectomy at the time of entering the protocol. These six received the doxorubicin in a neoadjuvant fashion and were thus evaluable for tumor response. The remaining 14 received doxorubicin as adjuvant therapy prior to intensification and transplantation. All patients underwent local-regional radiation therapy and were placed on oral tamoxifen. Doxorubicin was well tolerated in this schedule with all but three patients receiving all their cycles on schedule. Both BM and PBPC were easily collected after this regimen and, when reinfused, resulted in the prompt recovery of granulocytes (median 11 days to 500 absolute granulocyte count) and platelets (median 13 days to 20,000 platelets). The six patients who received doxorubicin prior to mastectomy all had major clinical responses, but were found to have microscopic focii of breast cancer in the mastectomy specimens. The overall treatment was well tolerated with the exception of one treatment-related death (5%). The overall and relapse free survival are 70% and 58% respectively with a median follow-up of 40 months (range 12-74 months). When the Stage IV patients are censored, the relapse-free survival rate is 69%. In the bone marrow transplant phase of treatment, the major non-hematologic toxicities were stomatitis (70%) and anorexia requiring parental nutrition (75%).
