Abstract
BACKGROUND Simple excision of earlobe keloids can result in recurrence rates approaching 80%. Many modalities have been suggested to reduce the risk of recurrence postoperatively, including intralesional steroids and radiotherapy. OBJECTIVE In order to determine the most reliable method to prevent keloid recurrence, we have conducted the first randomized, prospective trial comparing corticosteroid injections versus radiation therapy. RESULTS Thirty-one keloids were treated and followed for a minimum of 12.0 months. Two of 16 keloids (12.5%) recurred after surgery and radiation therapy, while 4 of 12 (33%) recurred after surgery and steroid injections. No alteration of skin pigmentation, wound dehiscence, chronic dermatitis, or neoplastic changes was observed in any patient in either group. Although a statistically significant difference was not observed, radiotherapy appeared to be more effective than steroid injections in preventing keloid recurrence. CONCLUSIONS Radiotherapy is a simpler treatment modality with better patient compliance, and patients were much more likely to complete treatment than with corticosteroid injections. We believe that radiotherapy can play an important role in the prevention of earlobe keloid recurrences, and that with current techniques, complications can be minimized. Further randomized study with additional patients is needed to compare the effectiveness of corticosteroid injections and radiotherapy in preventing keloid recurrence.

Abstract
We present the strain distribution patterns (SDPs) of 118 SSLP markers and three pigmentation genes that have been characterized in 27 strains from the LSXSS RI series. This coarse map provides a resource for linkage studies of phenotypes that are heritable in the LSXSS RI series. The LSXSS recombinant inbred (RI) strains were derived from the Long-Sleep (LS) and Short-Sleep (SS) selected lines of mice that were selected for differential sensitivity to ethanol but are also differentially sensitive to a variety of other alcohols, barbiturates, sedative hypnotics, and general anesthetics. Since the parents were not inbred, two atypical factors are present in these SDPs. First, more than two alleles are frequently found in these RIs, and second, some alleles can be uniquely associated with one or the other parent while other alleles may be found in both parental lines. To validate the markers found in the parental line, we genotyped all parental mice from one generation of both the LS and SS lines, thus leading to a set of marker SDPs that are useful for further phenotypic association and identification of provisional QTLs.

Abstract
Early motion should be begun as soon as possible after replantation but must be tailored to the specific injury. It is important to move joints and glide tendons and nerves within a safe short arc range of motion. This technique prevents many of the deleterious effects of immobilization, stiffness, and adhesion formation, at the same time protecting tendon, nerve, and vascular repairs. A well thought-out clinical plan for mobilization combined with a considerate and compassionate approach to the emotional, financial, and social needs of the patient ensures a good result.

Abstract
PURPOSE To study the toxicity and efficacy of combined granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) administration for mobilization of hematopoietic progenitor cells (HPCs). MATERIALS AND METHODS Cohorts of a minimum of five patients each were treated subcutaneously as follows: G-CSF 5 micrograms/kg on days 1 to 12 and GM-CSF at .5, 1, or 5 micrograms/kg on days 7 to 12 (cohorts 1, 2, and 3); GM-CSF 5 micrograms/kg on days 1 to 12 and G-CSF 5 micrograms/kg on days 7 to 12 (cohort 4); and G-CSF and GM-CSF 5 micrograms/kg each on days 1 to 12 (cohort 5). Ten-liter aphereses were performed on days 1 (baseline, pre-CSF), 5, 7, 11, and 13. Colony assays for granulocyte-macrophage colony-forming units (CFU-GM) and erythroid burst-forming units (BFU-E) were performed on each harvest. RESULTS The principal toxicities were myalgias, bone pain, fever, nausea, and mild thrombocytopenia, but none was dose-limiting. Four days of treatment with either G-CSF or GM-CSF resulted in dramatic and sustained increases in the numbers of CFU-GM per kilogram collected per harvest that represented 35.6 +/- 8.9- and 33.7 +/- 13.0-fold increases over baseline, respectively. This increment was attributable both to increased numbers of mononuclear cells collected per 10-L apheresis and to increased concentrations of progenitors within each collection. The administration of G-CSF to patients already receiving GM-CSF (cohort 4) caused the HPC content to surge to nearly 80-fold the baseline (P = .024); the reverse sequence, ie, the addition of GM-CSF to G-CSF, was less effective. The CFU-GM content of the baseline aphereses correlated with the maximal mobilization achieved (r = .74, P = .001). CONCLUSION Combined G-CSF and GM-CSF administration effectively and predictably mobilizes HPCs and facilitates apheresis.

Abstract
Increased carpal-tunnel pressure has been implicated in the pathophysiology of carpal tunnel syndrome, but it is not known whether splints that immobilize the wrist in a functional position of extension minimize carpal tunnel pressure. To determine the position of the wrist that results in the lowest carpal-tunnel pressure, twenty control subjects and four patients who had carpal tunnel syndrome were evaluated with use of a new, dynamic method that continuously measures carpal tunnel pressure throughout the range of motion of the wrist. The pressure was measured by means of a pressure transducer connected to a flexible catheter that had been inserted into the carpal canal. The position of the wrist was measured simultaneously with use of a two-axis electrogoniometer. Aided by a computer monitor that displayed a moving line of real-time carpal-tunnel pressure, each subject was instructed to move the wrist throughout the range of motion and to adjust it to the position that corresponded to the lowest carpal-tunnel pressure. For the control subjects, the lowest carpal-tunnel pressure averaged 8 +/- 4 millimeters of mercury (1.07 +/- 0.53 kilopascals), and the average position of the wrist associated with the lowest pressure was 2 +/- 9 degrees of extension and 2 +/- 6 degrees of ulnar deviation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To determine why blacks have a higher bone mineral density (BMD) and lower incidence of osteoporosis and fractures than whites, we investigated whether the secretion of GH is higher in black than in white men. Measurements of GH were obtained at 20-min intervals over 24 h and analyzed by deconvolution. BMD was determined by dual energy x-ray absorptiometry in 16 normal black and 17 normal white men, aged 20-40 yr. The 24-h integrated GH concentration 942 +/- 174 vs. 602 +/- 104 micrograms/L; P = 0.0495) and GH secretory burst amplitude (0.499 +/- 0.163 vs. 0.169 +/- 0.027 micrograms/L.min; P = 0.0482) were higher in black than in white men. GH burst frequency, half-duration, mass, and half-life were not different in the 2 groups. The serum 17 beta-estradiol level (162 +/- 12 vs. 108 +/- 11 pmol/L; P = 0.0011) was higher, and the serum insulin-like growth factor-binding protein 3 level (2.2 +/- 0.1 vs. 2.8 +/- 0.1 microgram/mL; P = 0.0001) was lower in black than in white men. BMD values for total body (1.22 +/- 0.02 vs. 1.14 +/- 0.02 g/cm2; P = 0.0041), forearm (0.69 +/- 0.01 vs. 0.66 +/- 0.01 g/cm2; P = 0.0211), trochanter (0.91 +/- 0.03 vs. 0.77 +/- 0.03 g/cm2; P = 0.0003), and femoral neck (1.08 +/- 0.03 vs. 0.93 +/- 0.03 g/cm2; P = 0.0007) were higher in black than in white men. Thus, serum 17 beta-estradiol level, GH secretion, and BMD values for the total body, forearm, trochanter, and femoral neck are greater in black than in white men. As estrogen is known to increase GH secretion and GH to increase bone mass, increases in circulating 17 beta-estradiol may contribute to the higher GH secretion and bone mass in black men.

Abstract
We report the construction of a high-resolution physical map of a 17-Mb region that encompasses the entire q12, q13.1, and q13.2 bands of human chromosome 19. The continuous map extends from a region approximately 400 kb centromeric of the D19S7 marker to the excision repair cross-complementing rodent repair deficiency complementation group 1 (ERCC1) locus. The ordered clone map has been obtained starting from a foundation of cosmid contigs assembled by automated fingerprinting and localized to the cytogenetic map by fluorescence in situ hybridization (FISH). Clonal continuity of the map has been achieved by binning and linking the premapped cosmid contigs by means of yeast artificial chromosomes (YACs). The map consists of a single contig composed of 169 YAC members (minimal spanning path of 18 YACs) linking 165 cosmid contigs. Eighty percent, or about 13.2 Mb of the entire region spanned by the map, has been resolved to the EcoRI restriction map level. Twenty-nine sequence-tagged sites associated with genetic markers or derived from FISH-mapped cosmids have been placed on the map. In addition to the ERCC1 gene area, the map includes the location of the creatine kinase muscle locus (CKM), imidazoledipetidase (PEPD), glucophosphate isomerase (GPI), myelin-associated glycoprotein (MAG), the apolipoprotein E and C (APOE and APOC) genes, and the ryanodine receptor (RYR1) gene. This type of map provides a source of continuously overlapping DNA segments at a level of resolution two orders of magnitude higher than that obtained using YACs alone. In addition, it provides ready-to-use reagents for detailed analyses at the gene level, FISH studies of chromosomal aberrations, and DNA sequencing.

Abstract
Consumer choice is a central principle of psychosocial rehabilitation and supported housing approaches. This study assessed level of housing choice and the relationship of choice to community success in supported housing demonstration projects in five states. Assessment of level of choice about housing revealed very limited housing options and a high degree of influence from service providers over housing choice. Despite few options, most respondents liked their housing option(s) and felt they had enough information to make a good housing decision. The relationship of choice to community success over time demonstrated that choice was positively related to housing satisfaction, residential stability, and psychological well-being. Discussion focuses on implications of the findings for mental health services and public policy.

Abstract
The incidence of osteoporosis and fractures of the hip and spine is lower in black than in white subjects. To determine whether bone mass is increased in black men and to assess the influence of body weight and age, bone mineral density (BMD) of the lumbar spine, trochanter, and femoral neck was measured by dual-photon absorptiometry in 59 normal white men and 40 black men between the ages of 20 and 50 years. Body weight and age were not different from each other in the two groups. BMD of the midradius was measured by single-photon absorptiometry. Multivariate regression was used for independent analysis of each group and for analysis of the two groups together. After adjusting for body weight, age was inversely related to BMD of the femoral neck in both blacks and whites and of the trochanter in blacks. When body weight was analyzed independently of age, it was a positive predictor for BMD of the midradius of black men and of the femoral neck in white men. Despite the racial differences in age and weight on BMD, there were no significant interactions between race and age or race and weight when the data from black and white men were combined. Race had a highly significant effect on BMD of the lumbar spine, trochanter, and femoral neck midradius, and BMD was higher in blacks than in whites at these sites.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Pleural effusion in the presence of cirrhosis and ascites is well recognized. Peritoneal fluid is thought to enter the pleural cavity either because of overloaded lymphatics or a structural defect between the peritoneal and chest cavities. Pleural effusion rarely occurs in the absence of demonstrable ascites. This report describes the scintigraphic diagnosis of peritoneo-pleural communication in a patient with cryptogenic cirrhosis and pleural effusion without ascites.

Abstract
The pregnancy-specific glycoprotein (PSG) gene family consists of 11 closely related genes that form a subgroup of the carcinoembryonic antigen (CEA) gene family on 19q13.2. Using a high-resolution restriction fragment fingerprinting technique, we have assembled 256 cosmids from the PSG region into a single 700-kb contig. Fluorescence in situ hybridization to sperm pronuclei and cosmid walking experiments indicated that this PSG contig was directly telomeric of CGM8 at the telomeric end of the CEA subgroup gene cluster. Detailed restriction mapping and hybridization with gene-specific probes indicated that the order of the 11 Previously identified PSG genes is cen-PSG3-PSG8-PSG12-PSG1-PSG6-PSG7-+ ++PSG13-PSG2-PSG5-PSG4-PSG11-tel. The CEA subgroup gene CGM11 is located at the telomeric end of the PSG gene cluster. The PSG genes are all oriented in tandem with the 5'-3' direction of transcription from telomere to centromere. The detailed map also led to the identification of seven new CEA family genes in this region. One of these (CGM12), located between CGM8 and PSG3, is a member of the CEA subgroup. The remaining six (CGM13 through CGM18) are interspersed among the PSG genes and appear to form a third distinct subgroup within the CEA gene family.

Abstract
The ability of MHC class II molecules to sort into the endocytic pathway has generally been attributed to the invariant chain glycoprotein. In this paper, we present evidence suggesting that lumenal sequences in the MHC class II molecule itself control the post-Golgi entry of class II into endosomes. Single amino acid changes have been introduced into a highly conserved region of the class II beta chain (amino acids 80-83). Mutant class II beta chain genes and wild-type alpha chain genes have been transfected into cells that lack both class II and invariant chain expression. Immunofluorescent staining of transfected cells indicates that single amino acid changes in this region of beta can positively or negatively modulate expression of class II in endocytic vesicles independently of invariant chain. Mutation at residue 80 leads to prominent localization in vesicular structures typical of late endocytic compartments, while a change at position 82 leads to arrest in the Golgi. These data argue in favor of the possibility that MHC class II molecules bear a sorting signal that allows access to MHC class II molecules into the endocytic pathway of antigen presenting cells.

Abstract
Two-hundred-eight women attending family planning clinics in New York City who received the Norplant contraceptive system during the first sixteen months of Norplant implants insertions were evaluated. Within this clinic population, Norplant implants were a popular contraceptive choice and were removed from 64 of the 208 recipients. Reasons for removal included bleeding, weight gain, and headache, and were consistent with those found in the clinical trials. Prior satisfaction with oral contraceptives did not predict success or failure with Norplant implants. The rate of follow-up visits to the family planning clinics was low. However, evidence exists that these women did not lose contact with the medical center and continued to receive health care.

Abstract
Transport proteins, acute-phase reactant proteins (APRP), hematology, and anthropometry were studied in 34 sickle cell disease (SCD) children (20 boys, 14 girls) and 27 controls without growth deficits (13 boys, 14 girls) [corrected]. The age range was 1/2 to 16 1/2 years. Weight deficits (< 80%) by Waterlow's classification were observed in 41% of SCD boys and 25% of SCD girls, and height deficits (< 90%) were observed in 25% SCD boys and 25% girls. Mean white blood cell counts were significantly higher (P < .001) and hematocrit and hemoglobin (Hb) lower (P < .005) in SCD children than in controls. Although both groups had similar mean levels of albumin, transferrin, and APRP, SCD children had significantly lower mean levels of retinol-binding protein (RBP) (P < .001) and retinol-prealbumin (P < .001). Retinol-binding protein levels were abnormal in 18 (53%) SCD children and in only 23% controls (chi 2 = 14.06; P < 0.005); transferrin levels were abnormal in 20% of SCD children and in none of the controls. Children with SC and SF Hb phenotype had normal mean levels of RBP, whereas those with S beta thal and SS phenotype had levels below normal. Growth-retarded children by weight and height had reduced mean levels of RBP and prealbumin compared with growth-normal SCD children. The implication of primary protein-energy malnutrition on growth retardation in SCD children is under study.

Abstract
We investigated how repetitive hand activity normally affects carpal tunnel pressure and whether a flexible wrist splint can influence this effect. Nineteen healthy subjects were evaluated under four test conditions: at rest with and without a wrist splint (baseline) and while performing a repetitive task with and without a wrist splint. The task involved loading and unloading 1 lb. cans from a box at a rate of 20 cans per minute for period of 5 minutes. Carpal tunnel pressure and wrist angles were continuously monitored by means of a fluid-filled catheter inserted into the carpal canal and a two-channel electrogoniometer mounted on the dorsum of the hand and forearm. Without the splint, carpal tunnel pressure rose from a median baseline level of 8 +/- 6 mmHg to 18 +/- 13 mmHg during activity. With the splint, carpal tunnel pressure rose from a baseline of 13 +/- 5 mmHg to 21 +/- 12 mmHg during activity. Median carpal tunnel pressure during activity with the splint was no different from that without the splint. Our data indicate that the median nerve is subjected to increased pressure within the carpal tunnel during repetitive hand activity. Wearing a flexible wrist splint during activity limits the range of wrist motion but has no significant effect on carpal tunnel pressure.
