Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
BACKGROUND Cluster randomised controlled trials (CRCTs) are increasingly used to evaluate the effectiveness of interventions for improving health. A key feature of CRCTs is that individuals in clusters are often more alike than individuals in different clusters, irrespective of treatment. This similarity within clusters needs to be taken into account when planning CRCTs to obtain adequate sample sizes, and when analysing clustered data to obtain correct estimates. METHODS Nationally representative data from 15 to 16 year olds were analysed, from 21 of the 35 countries that participated in the 2007 European School Survey Project on Alcohol and Other Drugs. Within country school level intra-class correlation coefficients (ICCs) were calculated for substance use (self-reported alcohol use, regular alcohol use, binge drinking, any smoking, regular smoking, and illicit drug use) and psychosocial health (depressive mood and self-esteem). Unadjusted and adjusted ICCs are presented. ICCs are adjusted for student sex and socioeconomic status. RESULTS ICCs ranged from 0.01 to 0.21, with the highest (0.21) reported for regular smoking. Within country school level ICCs varied substantially across health outcomes, and among countries for the same health outcomes. Estimated ICCs were consistently higher for substance use (range 0.01-0.21), than for psychosocial health (range 0.01-0.07). Within country ICCs for health outcomes varied by changes in the measurement of particular health outcomes, for example the ICCs for regular smoking (range 0.06-0.21) were higher than those for having smoked at all in the last month (range 0.03-0.17). CONCLUSIONS For school level ICCs to be effectively utilised in informing sample size requirements for CRCTs and adjusting estimates from meta-analyses, the school level ICCs need to be both country and outcome specific.

Abstract
BACKGROUND Sequential audits over a recent 30-year period from 1981 to 2010 have documented dermatological activity data for the same region of southeast Scotland approximately every 5 years, allowing demonstration of trends in workload. AIM To undertake similar assessments of outpatient dermatological activity using historical documentation from 1921 to 1965, and to compare trends with modern data. METHODS Historical records held in the libraries of the Department of Dermatology, Royal Infirmary, Edinburgh and in the University of Edinburgh were audited. Details of new dermatological outpatients were recorded for the months of September, October and November from 1921, and at 5-year intervals from 1925 to 1965. Patient age, sex and primary diagnosis were documented. Data were analysed and compared with those of previous audits of the same geographical population from 1981 to 2010. RESULTS Details of 11 225 new patients were analysed during the period 1921-1965, in conjunction with 7755 patients from the period 1981-2010, giving a total of 18 980 patients included in the study. The monthly number of patients increased by over 3000%, from 74 patients in 1921-2882 patients in 2010. Trends were seen in the following diagnostic categories. Between 1921 and 2010, benign tumours increased from 1% to 36% of workload and malignant tumours from 2% to 11%. Over the same time period, dermatitis decreased from 32% to 13%, and infections from 24% to 2%. Infestations referrals peaked at 12% in the 1940s, but declined to 1% in the 1950s. Viral warts peaked at 49% of patients in 1960 and fell to 3% in 2010. CONCLUSIONS Over a 90-year period, there has been a dramatic rise in new patient dermatological workload. We have found trends in presentations of common dermatological conditions. Outpatient dermatology now appears to be increasingly involved in the detection and treatment of skin malignancy. Although many inflammatory dermatoses remain important, infectious dermatoses are less commonly encountered, compared with historical activity.

Abstract
Grade 2 meniscal changes on MRI are linear signals confined within the meniscus thought to represent areas of meniscal degeneration or intrasubstance tears. It has been reported that in only 10% of cases is a meniscal tear detected during subsequent arthroscopy. Usually non-operative management is appropriate, but in some cases, grade 2 meniscal changes are seen on MRI in patients with a typical presentation of a meniscal tear. In this circumstance, an arthroscopic partial meniscectomy may be indicated and an MRI report, which describes the meniscus as being normal, may be confusing. A pilot study of 10 consecutive symptomatic patients (mean age 28.1 years) with a grade 2 meniscal signal on MRI was performed. At arthroscopy, with thorough examination of the meniscus using a probe, an intrasubstance tear was detected in all 10 patients. Partial meniscectomy was performed, with a mean follow-up of 6.7 months. All but one patient (due to other pathology) had marked improvement in pain and function. Thus, the authors believe that grade 2 signal changes should be reported in a manner that raises the possibility that they may cause symptoms and that the presence of any intrasubstance changes should be clearly conveyed in the report.

Abstract
Valganciclovir is commonly used for cytomegalovirus (CMV) prophylaxis in renal transplant patients. A fixed dose of 900 mg daily is typically recommended, however, there has never been a formal pharmacokinetic study comparing various doses in renal transplant patients. We therefore compared the pharmacokinetic characteristics of intravenous ganciclovir (IV GCV) and oral ganciclovir (GCV) with two different doses of valganciclovir (VGCV) in an open-label crossover study. Ten adult kidney recipients participated in a four-phase crossover treatment schedule of IV GCV (2.5 mg/kg every 12 h), VGCV (900 mg daily), VGCV (450 mg daily) and oral GCV (1000 mg Q8 H). IV GCV and oral VGCV 900 mg daily achieved similar values for AUC(0-24) (median 60.63 vs. 62.86 microg/h/mL). Oral VGCV 450 mg achieved comparable AUC(0-24) values as oral GCV 1000 mg Q8 H (median AUC(0-24) 35.9 vs. 29.04 microg/h/mL). Oral VGCV 900 mg daily provided systemic GCV exposure similar to IV GCV and confirms PV 16 000 study results. Further, VGCV 450 mg daily provided comparable systemic exposure versus oral GCV. Due to its favorable pharmacokinetic profile, data herein suggest that VGCV can be used in the early post-kidney transplant period, and that 450 mg daily provides ample drug exposure for effective CMV prophylaxis in kidney transplant patients.

Abstract
We report the first results from a search for weakly interacting massive particles (WIMPs) in the Cryogenic Dark Matter Search experiment at the Soudan Underground Laboratory. Four Ge and two Si detectors were operated for 52.6 live days, providing 19.4 kg d of Ge net exposure after cuts for recoil energies between 10 and 100 keV. A blind analysis was performed using only calibration data to define the energy threshold and selection criteria for nuclear-recoil candidates. Using the standard dark-matter halo and nuclear-physics WIMP model, these data set the world's lowest exclusion limits on the coherent WIMP-nucleon scalar cross section for all WIMP masses above 15 GeV/c2, ruling out a significant range of neutralino supersymmetric models. The minimum of this limit curve at the 90% C.L. is 4 x 10(-43) cm2 at a WIMP mass of 60 GeV/c2.

Abstract
Hypoxia plays a key role in the pathogenesis of acute mountain sickness (AMS), but individual susceptibility is variable and cerebral symptoms do not always correlate with PaO2 measurements. Cerebral hypoxia may be more relevant than PaO2. We studied trends in cerebral regional oxygen saturation by the technique of near-infrared spectroscopy in 20 subjects ascending rapidly to 4680 m. Subjects were enrolled in a placebo-controlled, double-blind trial of medroxyprogesterone for the prevention of AMS. The fall in cerebral oxygen saturation was less than in the periphery. At 4680 m, cerebral oxygenation correlated with peripheral saturation but not with PaCO2 or with cerebral symptoms scores. At 4680 m, subjects on medroxyprogesterone had higher cerebral and peripheral saturation compared with those on a placebo. We conclude that cerebral oxygenation monitored with the Critikon 2020 system provided important information on the complex relationship of hypoxia to AMS and that other factors, such as changes in blood flow or capillary permeability, may be equally important.

Abstract
OBJECTIVE To assess the difference in measured urethral function before and after tension-free vaginal tape procedure (TVT). METHODS Women who underwent TVT for genuine stress incontinence with or without intrinsic sphincter deficiency completed this study. Multichannel urodynamic testing was performed preoperatively and 6 weeks postoperatively. Maximum urethral closure pressure and pressure transmission ratio were recorded. Valsalva leak point pressures were determined at 150 mL and at full bladder capacity. Resting and straining urethral angles were measured using the cotton swab technique. Subjects completed both the Incontinence Impact Questionnaire and Urodynamic Distress Inventory preoperatively and postoperatively. RESULTS Thirty-five consecutive women were studied. Twenty-three (65.7%) had a preoperative diagnosis of intrinsic sphincter deficiency as defined by maximum urethral closure pressure less than 20 cm H(2)O and/or Valsalva leak point pressure less than 60 cm H(2)O. Subjective and objective success rates were 91% and 83%, respectively. Subjects showed an 86.8% (95% CI 71.9%, 100.0%) improvement in their Incontinence Impact Questionnaire score and a 72.9% (95% CI 62.6%, 83.1%) improvement in their Urodynamic Distress Inventory score. The mean change in maximum urethral closure pressure was -1.3 cm H(2)O (95% CI -5.9, 3.3), whereas the pressure transmission ratio increased 15.7% (95% CI 5.0%, 26.3%). The mean decrease in straining urethral angle was 16.3 degrees (95% CI -23.9 degrees, -8.7 degrees ). Cured subjects demonstrating hypermobility preoperatively continued to do so postoperatively. CONCLUSION There was a significant increase in pressure transmission ratio, but not maximum urethral closure pressure, after TVT. These changes are similar to those reported after retropubic urethropexy and traditional sling procedures. The effectiveness of the TVT sling does not appear to depend on a clinically significant change in the straining urethral angle.

Abstract
PURPOSE We developed a pneumonia guideline at Intermountain Health Care that included admission decision support and recommendations for antibiotic timing and selection, based on the 1993 American Thoracic Society guideline. We hypothesized that guideline implementation would decrease mortality. SUBJECTS AND METHODS We included all immunocompetent patients > 65 years with community-acquired pneumonia from 1993 through 1997 in Utah; nursing home patients were excluded. We compared 30-day mortality rates among patients before and after the guideline was implemented, as well as among patients treated by physicians who did not participate in the guideline program. RESULTS We observed 28,661 cases of pneumonia, including 7,719 (27%) that resulted in hospital admission. Thirty-day mortality was 13.4% (1,037 of 7,719) among admitted patients and 6.3% (1,801 of 28,661) overall. Mortality rates (both overall and among admitted patients) were similar among patients of physicians affiliated and not affiliated with Intermountain Health Care before the guideline was implemented. For episodes that resulted in hospital admission after guideline implementation, 30-day mortality was 11.0% among patients treated by Intermountain Health Care-affiliated physicians compared with 14.2% for other Utah physicians. Analysis that adjusted by logistic regression for age, sex, rural versus urban residences, and year confirmed that 30-day mortality was lower among admitted patients who were treated by Intermountain Health Care-affiliated physicians (odds ratio [OR]: 0.69; 95% confidence interval [CI]: 0.49 to 0.97; P = 0.04) and was somewhat lower among all pneumonia patients (OR: 0.81; 95% CI: 0.63 to 1.03; P = 0.08). CONCLUSION Implementation of a pneumonia practice guideline in the Intermountain Health Care system was associated with a reduction in 30-day mortality among elderly patients with pneumonia.

Abstract
We present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23x10(6) Upsilon(4S)-->BbarB decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events in which one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2beta, is derived from the decay time distributions in such events. The result is sin2beta = 0.34+/-0.20 (stat)+/-0.05 (syst).

Abstract
The authors determined the prevalence and demographic features of drug use disorders in a database of 565 veteran geropsychiatric inpatients. Twenty-four patients (4%) were diagnosed with nonalcoholic substance use disorders, including 18 (3%) with prescription drug use disorders and 6 (1%) with illegal drug use disorders. The patients diagnosed with prescription drug use disorders were predominantly Caucasian, whereas those diagnosed with illegal substance use disorders were predominantly African American. No other significant demographic differences were noted. Nonalcohol substance use disorders represent an unappreciated problem in psychiatrically hospitalized older adults, with illegal substance use disorders making up a larger than expected proportion of this group.

Abstract
The atypical antipsychotics are gradually becoming the mainstay of treatment for psychosis in the elderly. The present study examines the effectiveness and tolerability of risperidone and olanzapine treatment in 34 matched male patients admitted to a VA Medical Center geriatric inpatient unit. The Positive and Negative Syndrome Scale for Schizophrenia (PANSS), the Cohen-Mansfield Agitation Inventory (CMAI), the Rating Scale for Side-Effects, the Extra-Pyramidal Rating Scale, and the Mini-Mental State Examination were administered at admission and discharge. T-tests at admission and discharge across groups indicate that the patients as a whole were performing significantly better following their stay on the CMAI (t(30)=4.31, p=0.000), the GAF (t(31)=9.73, p=0.000), the PANSS total score (t(29)=3.82, p=0.001), and the positive symptom portion of the PANSS (t(28)=4.29, p=0.000). No significant differences were detected between the two groups with regard to length of hospitalization, or reduction in scores on the PANSS, or CMAI, however the daily cost of risperidone was 1/3 as much as olanzapine (p=0.00). The two treatments were comparable in the elderly men evaluated in this study.

Abstract
INTRODUCTION In certain emergency medical services (EMS) systems, emergency medical technicians-paramedics (EMT-Ps) repair lacerations in the field. This practice is supported by studies showing equivalence between nonphysicians and physicians regarding infection rates and cosmetic outcomes. OBJECTIVE To evaluate the ability of emergency medical technicians-basic (EMT-Bs) to identify wounds repairable in the field or requiring tetanus prophylaxis. METHODS This was a prospective, double-blind convenience sample study at an urban teaching hospital. Eleven EMT-B volunteers, trained by a one-hour lecture and bedside teaching, evaluated lacerations for prehospital repair by answering three questions: Could this wound be repaired in the field, and if no, why not? If on an adult forearm, could this wound be repaired in the field, and if no, why not? Does this patient need tetanus prophylaxis, and if no, why not? A blinded principal investigator also answered these questions, and a person uninvolved in the study correlated results. Statistical evaluation was performed using kappa statistics. RESULTS The EMT-Bs identified 17 of 17 potentially repairable wounds and 163 of 163 wounds excluded from prehospital repair. Placing the wound on the forearm, the EMT-Bs identified 82 of 87 potentially repairable wounds and 93 of 93 wounds excluded from prehospital repair (sensitivity 94%, specificity 100%, positive predictive value 100%, negative predictive value 95%, kappa 0.97). For five of five wounds, physicians disagreed with the EMT-Bs and thought the wound repairable prehospital. The EMT-Bs and physicians agreed on individual wound exclusion criteria in 207 of 239 (86.6%) instances. Finally, the EMT-Bs identified 108 of 108 patients requiring tetanus prophylaxis. CONCLUSIONS Basic EMTs can accurately identify wounds eligible for prehospital repair and/or requiring tetanus prophylaxis.

Abstract
The Cryogenic Dark Matter Search (CDMS) employs Ge and Si detectors to search for weakly interacting massive particles (WIMPs) via their elastic-scattering interactions with nuclei while discriminating against interactions of background particles. CDMS data, accounting for the neutron background, give limits on the spin-independent WIMP-nucleon elastic-scattering cross section that exclude unexplored parameter space above 10 GeV/c2 WIMP mass and, at >75% C.L., the entire 3sigma allowed region for the WIMP signal reported by the DAMA experiment.

Abstract
OBJECTIVE We performed a quantitative study to determine whether mixed urinary incontinence was associated with any ultrastructural changes in detrusor and urethral smooth muscle. STUDY DESIGN Detrusor and urethral smooth muscle biopsy specimens were obtained at the time of laparotomy from 5 women aged 35 to 65 years with mixed urinary incontinence and from a control group of 5 continent women. Smooth muscle morphologic characteristics were assessed from a systematic random sample of electron micrographs. A further 16 urethral biopsy specimens were similarly analyzed to confirm the findings of the initial study. RESULTS The electron-dense portion of the sarcolemma was smaller in urethral biopsy specimens taken from patients with intrinsic sphincter deficiency than in those from control subjects (chi(2)((1)) = 4.9; P =.027). No other morphologic characteristics were unique to patients with incontinence. CONCLUSIONS Our study suggests that focal adhesion architecture is decreased in urethral smooth muscle of patients with intrinsic sphincter deficiency.

Abstract
Contact biocides are a relatively new form of infection-resistant materials. Surfacine is a silver based antimicrobial coating that can be immobilized on the surface of most alloplastic materials used to fabricate devices. It exhibits broad-spectrum antimicrobial activity exclusively at the surface without elution and does not induce antimicrobial activity in contacting fluids such as urine regardless of volume. Because it is permanently immobilized on the material surface, the coating is nontoxic to cells and is not anticipated to exhibit immunogenicity, teratogenicity, or carcinogenicity.

Abstract
Cerebral oxygenation is likely to be of critical importance in determining function at high altitude. The present study has used the technique of near-IR spectroscopy to monitor changes in cerebral regional oxygenation in response to inhaled carbon dioxide, hyperventilation and supplementary oxygen on ascent to 4680 m over 3 days. At sea level, inhaled CO(2) resulted in a significant rise in cerebral regional oxygenation [from mean 69.6% (S.D. 2.4% to 71. 1+/-2.3%; means+/-S.D.; P<0.001). At 4680 m, CO(2) increased regional cerebral oxygenation (63.8+/-2.5% to 65.9+/-2.2%; P<0.001) and also increased peripheral oxygen saturation (75.1+/-6.1% to 83. 6+/-4.0%; P<0.001). Voluntary hyperventilation resulted in improved peripheral oxygen saturation at 2770 m, 3650 m and 4680 m, whereas cerebral regional oxygenation was reduced at sea level and at 2770 m, unchanged at 3650 m and increased at 4680 m. Supplementary oxygen (6 1itres/min) at 4680 m resulted in greater improvements in peripheral oxygen saturation (76.7+/-7.9% to 98.1+/-1.5%; P<0.001) and cerebral regional oxygenation (64.6+/-3.3% to 70.6+/-2.9%; P<0. 001) than were found with CO(2) or hyperventilation. We conclude that attempts to increase CO(2) inhalation or ventilation at high altitude are likely to be beneficial for cerebral oxygenation in the short term.

Abstract
OBJECTIVE Cross-cultural differences in treatment and diagnosis exist in several psychiatric disorders. This study examines phenomenological and treatment differences between Caucasian and African-American patients presenting to a geropsychiatric unit for treatment of behavioral disturbances associated with dementia. METHODS One hundred and forty-one Caucasian patients were compared to 56 African-American patients consecutively admitted to a VA geropsychiatric inpatient unit. At admission, differences in behavior disturbances between the two groups were examined using the Mini-Mental State Examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI), Hamilton Rating Scale for Depression (HAM-D), Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). Differences in treatment were assessed by comparing medication types and doses between the two groups. RESULTS AND CONCLUSION Results showed that Caucasian and African-American patients with dementia and behavioral disturbances presented and responded similarly to like treatment on an inpatient geropsychiatric unit. The similarity between the two groups may be explained by the multi-ethnic make-up of the interdisciplinary treatment team and by the use of standardized scales to measure symptomatology and response.

Abstract
Overall performance, including ease of use, total hands-on time, incubation and processing times, sensitivity, and specificity, of each of nine enzyme-linked immunosorbent assays (ELISAs) were compared by using 222 individual fecal samples submitted for the detection of Giardia lamblia. The assays evaluated were manufactured by Alexon, Inc., Cambridge Biotech Corp., Meridian, Inc., and Trend Scientific, Inc. All assays used polyclonal antibodies except the "new and improved" Microplate (direct and diluted methods) by Alexon, which is a monoclonal antibody assay. Seventy specimens were positive for G. lamblia by ELISA, ova and parasite test, and/or direct fluorescent-antibody assay. One hundred fifty two were negative by all three methods. Sensitivities and specificities ranged from 88.6 to 100% and 99.3 to 100%, respectively. The total hands-on time needed to run one specimen ranged from 1 min to 2 min 17 s per specimen. All except one commercially available ELISA were found to be rapid, sensitive, and specific for the detection of G. lamblia in fecal specimens.

Abstract
A total of 417 fecal samples preserved in 10% buffered formalin and PVA were submitted to a commercial microbiology laboratory only for the detection of Giardia lamblia. Results from fecal specimens collected from 411 patients with gastrointestinal symptoms were compared using the following methods: (a) standard Ova & Parasite (O&P) concentration; (b) Alexon's ProspecT/Giardia enzyme-linked immunosorbent assay (ELISA) test, and (c) Meridian's Direct Fluorescent Antibody (DFA) Stain. In the 29 specimens in which G. lamblia was detected, 10 were O&P, DFA and ELISA positive, 17 were only ELISA positive and two were only Ova & Parasite and Direct Fluorescent Antibody positive. Of the 29 positive specimens, 22 were confirmed as true positives. The ELISA sensitivity was 91% and the specificity was 98%. The expense associated with these methods to detect the presence of Giardia is $11.00, $8.95, and $12.80, respectively. In symptomatic patients, the ProspecT/Giardia ELISA is a cost-effective, rapid, and sensitive method for detecting the presence of G. lamblia in fecal specimens.

Abstract
We surveyed Utah general internists (N = 134) regarding their attitudes toward and practices associated with telephone management of upper respiratory tract infections. The questionnaire contained 3 case vignettes--viral upper respiratory tract infection, streptococcal pharyngitis, and acute infectious epiglottitis--and a series of questions were asked about telephone diagnosis, management preferences (clinic versus telephone), and telephone management practices. The 53 respondents (40%) were able to make important diagnostic distinctions about upper respiratory tract infections from a written vignette. As the likelihood of a complicated or serious condition increased, patients would be appropriately triaged for clinical evaluation. Most internists would make a written record of the telephone conversation. Only 1 internist of the 53 would charge for telephone management.

Abstract
Triplicate preserved fecal samples from 265 patients were pooled into single samples, and the recovery rate of intestinal parasites from the pooled samples was compared with that from the individual samples. Parasites were detected in 109 patients when results from the individual samples were used compared with 108 patients when results from the pooled specimens were used. Pooling preserved fecal samples is an efficient and economical procedure for the detection of ova and parasites.

Abstract
In a blind comparison, 465 randomly collected clinical fecal specimens were examined. Hemo-De was found to be an excellent replacement for ethyl acetate in the concentration procedure and for carbol-xylene and xylene in the trichrome staining procedure. Elimination of toxic reagents, combined with its lower cost, makes Hemo-De the preferred choice in routine parasitology examinations.

Abstract
To investigate the characteristics of primary cardiac valve tumors, we retrospectively analyzed our multiinstitutional experience from 1932 through 1990. We encountered 56 valvular tumors in 53 patients. The average age of these patients was 52 years (range, 2 to 88 years) and 79% (42/53) were male. Symptoms were present in 38% (20/53) and were neurological in 15% (8/53). Four patients experienced sudden death. Each of the four valves was affected with approximately equal frequency: 16 aortic, 15 mitral, 13 pulmonary, and 12 tricuspid. All but four tumors were benign. The most common histological type was papillary fibroelastoma (41), followed by myxomas (5), fibromas (4), sarcomas (2), hamartoma (1), hemangioma (1), histiocytoma (1), and undifferentiated (1). Average tumor size was 1.15 cm (range, 3 mm to 7 cm), and the average size of fibroelastomas was 8 mm (range, 3 to 15 mm). Mitral valve tumors were more likely than aortic valve tumors to produce serious neurological symptoms or sudden death (8/15 versus 3/16; p less than 0.05). Six patients underwent echocardiography, and results were positive in each. All 6 underwent uncomplicated valve repair or replacement. Compared with a series of 407 nonvalvular tumors, cardiac valve tumors are more likely to occur in male patients (p less than 0.001) and adults (p less than 0.001). Valve tumors are also more commonly benign (p less than 0.001) and asymptomatic (p less than 0.001). These tumors demonstrate somewhat less aggressive behavior compared with non-valvular tumors, but their distinct propensity to produce serious clinical sequelae argues in favor of surgical resection for all cardiac valve tumors.

Abstract
This study was undertaken to determine the frequency of variations involving the anatomy of Guyon's canal. A series of 58 wrist dissections revealed a 22.4% incidence of anomalous muscles and a 1.7% incidence of anomalous nerve paths. The relationship of the deep branch of the ulnar artery to the superficial and deep branches of the ulnar nerve was found to vary. Accessory muscles passing through Guyon's canal are common, and are often found bilaterally. Aberrant branching of the ulnar nerve in this area is rare.
