Cephalalgiaphobia: A Possible Specific Phobia Of Illness., Mario F P Peres, Juliane P P Mercante, Vera Z Guendler, Felipe Corchs, Marcio A Bernik, Eliova Zukerman, Stephen Silberstein

Department of Jefferson Headache Center Papers and Presentations

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild …

The Feminisation Of British Neurology: Implications For Workforce Planning., C. B. Carroll, Dsnap Tengah, C. Lawthom, G. Venables

Peninsula Medical School

As in other hospital specialties, an increasing proportion of neurology trainees are female. To predict the workforce implications it is necessary to determine what life choices future neurologists will make. A questionnaire survey of life choices was administered to neurology consultants and trainees, general medical senior house officers, and medical students. Of the 344 respondents, 3% of specialist registrars (SpRs) and 4.6% of consultants work part time. Eighty-seven per cent of female and 22% of male junior doctors plan to work part time for, on average, 7.5 and 1.5 years respectively. Thirty percent of consultants also plan to work part …

Repression Of Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (Trail) But Not Its Receptors During Oral Cancer Progression, Nadarajah Vigneswaran, Darryl C. Baucum, Jean Wu, Yahuan Lou, Jerry Bouquot, Susan Muller, Wolfgang Zacharias

Faculty, Staff and Student Publications

BACKGROUND: TRAIL plays an important role in host immunosurveillance against tumor progression, as it induces apoptosis of tumor cells but not normal cells, and thus has great therapeutic potential for cancer treatment. TRAIL binds to two cell-death-inducing (DR4 and DR5) and two decoy (DcR1, and DcR2) receptors. Here, we compare the expression levels of TRAIL and its receptors in normal oral mucosa (NOM), oral premalignancies (OPM), and primary and metastatic oral squamous cell carcinomas (OSCC) in order to characterize the changes in their expression patterns during OSCC initiation and progression. METHODS: DNA microarray, immunoblotting and immunohistochemical analyses were used to …

Effects Of A Personified Guide On Adherence To An Online Program For Alcohol Abusers., Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

The quality of the therapeutic alliance has robust effects on the outcome of psychotherapy and psychopharmacologic interventions. Automated behavioral health programs that are being developed to increase access to mental health treatment are administered in the absence of direct human participation, thereby precluding the development of a traditional therapeutic relationship. The aim of this study was to develop a personified guide designed to stimulate reactions similar to those experienced in a therapeutic relationship, and evaluate the effect of the guide on adherence to and satisfaction with an online alcohol use evaluation program. After completing a battery of four standard questionnaires …

Wilson, Manisha Bahl, Hong Zhao, Liming Yang, John Powell, Richard Simon, Wing C. Chan, Louis M. Staudt

Journal Articles: Pathology and Microbiology

BACKGROUND: The distinction between Burkitt's lymphoma and diffuse large-B-cell lymphoma is crucial because these two types of lymphoma require different treatments. We examined whether gene-expression profiling could reliably distinguish Burkitt's lymphoma from diffuse large-B-cell lymphoma.

METHODS: Tumor-biopsy specimens from 303 patients with aggressive lymphomas were profiled for gene expression and were also classified according to morphology, immunohistochemistry, and detection of the t(8;14) c-myc translocation.

RESULTS: A classifier based on gene expression correctly identified all 25 pathologically verified cases of classic Burkitt's lymphoma. Burkitt's lymphoma was readily distinguished from diffuse large-B-cell lymphoma by the high level of expression of c-myc target …

Analysis Of Epstein-Barr Virus Reservoirs In Paired Blood And Breast Cancer Primary Biopsy Specimens By Real Time Pcr., R Serene Perkins, Katherine Sahm, Cindy Marando, Diana Dickson-Witmer, Gregory R Pahnke, Mark Mitchell, Nicholas J Petrelli, Irving M Berkowitz, Patricia Soteropoulos, Virginie M Aris, Stephen P Dunn, Leslie J Krueger

Department of Surgery Faculty Papers

INTRODUCTION: Epstein-Barr virus (EBV) is present in over 90% of the world's population. This infection is considered benign, even though in limited cases EBV is associated with infectious and neoplastic conditions. Over the past decade, the EBV association with breast cancer has been constantly debated. Adding to this clinical and biological uncertainty, different techniques gave contradictory results for the presence of EBV in breast carcinoma specimens. In this study, minor groove binding (MGB)-TaqMan real time PCR was used to detect the presence of EBV DNA in both peripheral blood and tumor samples of selected patients. METHODS: Peripheral blood and breast …

Atypical Features In Pleomorphic Adenoma--A Clinicopathologic Study And Implications For Management., M. Ethunandan, R. Witton, G. Hoffman, A. Spedding, P. A. Brennan

Peninsula Dental School

Pleomorphic adenoma is the most common salivary gland neoplasm and infrequently undergoes malignant transformation. Carcinoma ex pleomorphic adenoma is typically an infiltrative neoplasm with features of cellular pleomorphism, high mitotic activity, peri-neural and vascular invasion. More recently, sub-groups of pleomorphic adenoma have been described exhibiting vascular invasion and features of malignancy without evidence of extra-capsular extension. There is little information in the literature regarding how these different histological variants influence clinical presentation and outcome following primary treatment. Following a review of 100 consecutive pleomorphic adenomas removed from the major salivary glands, 4 cases with atypical histological features were found. Three …

Basal Endothelial Nitric Oxide Release Is Preserved In Overweight And Obese Adults, Christopher A Desouza, Gary P. Van Guilder, Jared J Greiner, Derek T Smith, Greta L Hoetzer, Brian L Stauffer

Health and Nutritional Sciences Faculty Publications

OBJECTIVE: Impaired basal nitric oxide release is associated with a number of cardiovascular disorders including hypertension, arterial spasm, and myocardial infarction. We determined whether basal endothelial nitric oxide release is reduced in otherwise healthy overweight and obese adult humans.
RESEARCH METHODS AND PROCEDURES: Seventy sedentary adults were studied: 32 normal weight (BMI/m(2)), 24 overweight (BMI > or = 25 < 30 kg/m(2)), and 14 obese (BMI > or = 30 kg/m(2)). Forearm blood flow (FBF) responses to intra-arterial infusions of N(g)-monomethyl-L-arginine (5 mg/min), a nitric oxide synthase inhibitor, were used as an index of basal nitric oxide release.
RESULTS: N(g)-monomethyl-L-arginine elicited significant reductions in FBF in the normal weight …

The Meaning Of Computers To A Group Of Men Who Are Homeless., Kathleen Swenson Miller, Stacey Bunch-Harrison, Brett Brumbaugh, Rekha Sankaran Kutty, Kathleen Fitzgerald

Department of Occupational Therapy Faculty Papers

The purpose of this pilot study was to explore the experience with computers and the meaning of computers to a group of homeless men living in a long-term shelter. This descriptive exploratory study used semistructured interviews with seven men who had been given access to computers and had participated in individually tailored occupation based interventions through a Work Readiness Program. Three themes emerged from analyzing the interviews: access to computers, computers as a bridge to life-skill development, and changed self-perceptions as a result of connecting to technology. Because they lacked computer knowledge and feared failure, the majority of study participants …

A Pilot Randomized, Controlled Trial Of An In-Home Drinking Water Intervention Among Hiv + Persons, John M. Colford, Sona R. Saha, Timothy J. Wade, Catherine C. Wright, Mai Vu, Sandra Charles, Peter Jensen, Alan Hubbard, Deborah A. Levy, Joseph N. S. Eisenberg

Journal Articles: Epidemiology

Although immunocompromised persons may be at increased risk for gastrointestinal illnesses, no trials investigating drinking water treatment and gastrointestinal illness in such patients have been published. Earlier results from San Francisco suggested an association (OR 6.76) between tap water and cryptosporidiosis among HIV + persons. The authors conducted a randomized, triple-blinded intervention trial of home water treatment in San Francisco, California, from April 2000 to May 2001. Fifty HIV-positive patients were randomized to externally identical active (N = 24) or sham (N = 26) treatment devices. The active device contained a filter and UV light; the sham provided no treatment. …

A Randomized, Controlled Trial Of In-Home Drinking Water Intervention To Reduce Gastrointestinal Illness, John M. Colford, Timothy J. Wade, Sukhminder K. Sandhu, Catherine C. Wright, Sherline Lee, Susan Shaw, Kim Fox, Susan Burns, Anne Benker, M. Alan Brookhart, Mark Van Der Laan, Deborah A. Levy

Journal Articles: Epidemiology

Trials have provided conflicting estimates of the risk of gastrointestinal illness attributable to tap water. To estimate this risk in an Iowa community with a well-run water utility with microbiologically challenged source water, the authors of this 2000-2002 study randomly assigned blinded volunteers to use externally identical devices (active device: 227 households with 646 persons; sham device: 229 households with 650 persons) for 6 months (cycle A). Each group then switched to the opposite device for 6 months (cycle B). The active device contained a 1-microm absolute ceramic filter and used ultraviolet light. Episodes of "highly credible gastrointestinal illness," a …

Collecting Duct Carcinoma Of The Kidney: An Immunohistochemical Study Of 11 Cases., Andrea Vecchione, Tommaso Prayer Galetti, Marina Gardiman, Hideshi Ishii, Enrico Giarnieri, Francesco Pagano, Leonard G Gomella, Carlo M Croce, Raffaele Baffa

Department of Urology Faculty Papers

BACKGROUND: Collecting duct carcinoma (CDC) is a rare but very aggressive variant of kidney carcinoma that arises from the epithelium of Bellini's ducts, in the distal portion of the nephron. In order to gain an insight into the biology of this tumor we evaluated the expression of five genes involved in the development of renal cancer (FEZ1/LZTS1, FHIT, TP53, P27kip1, and BCL2). METHODS: We studied eleven patients who underwent radical nephrectomy for primary CDC. All patients had an adequate clinical follow-up and none of them received any systemic therapy before surgery. The expression of the five markers for tumor initiation …

Mexican Americans are the largest subgroup of Hispanics, the largest minority population in the United States. Stroke is the leading cause of disability and third leading cause of death. The authors compared stroke incidence among Mexican Americans and non-Hispanic Whites in a population-based study. Stroke cases were ascertained in Nueces County, Texas, utilizing concomitant active and passive surveillance. Cases were validated on the basis of source documentation by board-certified neurologists masked to subjects' ethnicity. From January 2000 to December 2002, 2,350 cerebrovascular events occurred. Of the completed strokes, 53% were in Mexican Americans. The crude cumulative incidence was 168/10,000 in …

Predictors Of Paralysis In The Rheumatoid Cervical Spine In Patients Undergoing Total Joint Arthroplasty., Jonathan N Grauer, Edwin M Tingstad, Nahshon Rand, Michael J Christie, Alan Hilibrand

Rothman Institute Papers

BACKGROUND: Rheumatoid arthritis is sometimes associated with radiographic evidence of instability of the cervical spine, most commonly an abnormal subluxation between vertebrae. When this instability compromises the space that is available for the spinal cord, it may be predictive of paralysis. However, the prevalence of radiographic signs of instability that are predictive of paralysis among patients with nonspinal orthopaedic manifestations of rheumatoid arthritis is unknown.

METHODS: Radiographs of the cervical spine of patients with rheumatoid arthritis who had undergone total joint arthroplasty over a five-year period were retrospectively reviewed. The radiographs were evaluated for predictors of paralysis (a posterior atlantodental …

Comparison Of Transcranial Electric Motor And Somatosensory Evoked Potential Monitoring During Cervical Spine Surgery., Alan S Hilibrand, Daniel M Schwartz, Venkat Sethuraman, Alexander R Vaccaro, Todd J Albert

Rothman Institute Papers

BACKGROUND: There has been little enthusiasm for somatosensory evoked potential monitoring in cervical spine surgery as a result, in part, of the increased risk of motor tract injury at this level, to which somatosensory monitoring may be insensitive. Transcranial electric motor evoked potential monitoring allows assessment of the motor tracts; therefore, we compared transcranial electric motor evoked potential and somatosensory evoked potential monitoring during cervical spine surgery to determine the temporal relationship between the changes in the potentials demonstrated by each type of monitoring and neurological sequelae and to identify patient-related and surgical factors associated with intraoperative neurophysiological changes.

METHODS: …

Differences In Peripheral Noradrenergic Function Among Actively Drinking And Abstinent Alcohol-Dependent Individuals., Ashwin A. Patkar, Charles A. Marsden, Prakash C. Naik, David A. Kendall, Raman Gopalakrishnan, Michael J. Vergare, Stephen P. Weinstein

Department of Psychiatry and Human Behavior Faculty Papers

We examined whether excessive alcohol consumption was related to changes in plasma levels of noradrenaline (NA) and whether these changes recover following abstinence. We also explored whether there were differences in NA levels between Type I and Type II alcoholics and controls during active drinking and abstinence. Plasma concentrations of NA were determined in (1) 27 Caucasian men with alcohol dependence who were regularly drinking (active drinkers) within 24 hours of hospitalization, (2) 29 Caucasian alcohol-dependent men who were in remission (abstinent for a minimum of three months), and (3) 28 race- and gender-matched healthy controls. NA concentrations were significantly …

Stroke In Devon: Knowledge Was Good, But Action Was Poor., C. Carroll, J. Hobart, C. Fox, L. Teare, J. Gibson

Peninsula Medical School

BACKGROUND AND AIM: Effective implementation of early treatment strategies for stroke requires prompt admission to hospital. There are several reasons for delayed admission. Good awareness should facilitate early admission. We identified local targets for education. METHODS: Four groups, each of 40 people, completed questionnaires to determine their knowledge of stroke symptoms and risk factors, and the action they took or would take in the event of a stroke. The groups were: patients with a diagnosis of stroke or TIA (within 48 hrs of admission); patients at risk of stroke; the general population; and nurses. RESULTS: Forty per cent of stroke …

Relationship Between Serotonin Transporter Gene Polymorphisms And Platelet Serotonin Transporter Sites Among African-American Cocaine-Dependent Individuals And Healthy Volunteers., Ashwin A. Patkar, Wade H. Berrettini, Paolo Mannelli, Raman Gopalakrishnan, Margret R. Hoehe, Louai Bilal, Stephen Weinstein, Michael J. Vergare

Department of Psychiatry and Human Behavior Faculty Papers

Alterations in the serotonin transporter (5-HTT) have been implicated in a variety of psychiatric disorders including cocaine dependence. A polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) appears to influence the expression of 5-HTT in human cell lines. We investigated whether 5-HTTLPR variants were related to differences in measures of platelet 5-HTT sites in cocaine-dependent patients and healthy volunteers (controls). Polymerase chain reaction-based genotyping of a 44 base pair insertion/deletion polymorphism in 5-HTTLPR was performed in 138 cocaine-dependent African-American subjects and 60 African-American controls. This yielded a short (S) and a long (L) allele. Platelet 5-HTT sites …

Mitotic Rate And Younger Age Are Predictors Of Sentinel Lymph Node Positivity: Lessons Learned From The Generation Of A Probabilistic Model., Vernon K Sondak, Jeremy M G Taylor, Michael S Sabel, Yue Wang, Lori Lowe, Amelia C Grover, Alfred E Chang, Alan M. Yahanda Md, Facs, James Moon, Timothy M Johnson

PCI Publications and Projects

BACKGROUND: Sentinel lymph node (SLN) biopsy allows surgeons to identify patients with subclinical nodal involvement who may benefit from lymphadenectomy and, possibly, adjuvant therapy. Several factors have been variably, and sometimes discordantly, reported to have predictive value for SLN metastasis to best select which patients require SLN biopsy.

METHODS: We reviewed 419 patients who underwent SLN biopsy for melanoma from a prospectively collected melanoma database. To derive a probabilistic model for the occurrence of a positive SLN, a multivariate logistic model was fit by using a stepwise variable selection method. The accuracy of each model was evaluated by using receiver …

Jones

Journal Articles: Epidemiology

In August 2000, the Ohio Department of Health requested assistance to investigate a cryptosporidiosis outbreak with more than 700 clinical case-patients. An epidemiologic and environmental investigation was conducted. Stool specimens, pool water, and sand filter samples were analyzed. A community-based case-control study showed that the main risk factor was swimming in pool A (odds ratio [OR] = 42, 95% confidence interval [CI] = 12.3-144.9). This was supported by results of polymerase chain reaction (PCR) analysis, which showed the presence of both the human and bovine genotypes of Cryptosporidium parvum in case-patients and samples from the filter of pool A. A …

In response to the emergence of severe acute respiratory syndrome (SARS), the United States established national surveillance using a sensitive case definition incorporating clinical, epidemiologic, and laboratory criteria. Of 1,460 unexplained respiratory illnesses reported by state and local health departments to the Centers for Disease Control and Prevention from March 17 to July 30, 2003, a total of 398 (27%) met clinical and epidemiologic SARS case criteria. Of these, 72 (18%) were probable cases with radiographic evidence of pneumonia. Eight (2%) were laboratory-confirmed SARS-coronavirus (SARS-CoV) infections, 206 (52%) were SARS-CoV negative, and 184 (46%) had undetermined SARS-CoV status because of …

Modeling Of Hemoglobin In Dengue Fever And Dengue Hemorrhagic Fever Using Bioelectrical Impedance, F. Ibrahim, N.A. Ismail, M.N. Taib, W.A.B. Wan Abas

Research Publications (2000 to 2005)

This paper describes a model for predicting hemoglobin (Hb) by using bioelectrical impedance analysis (BIA) in dengue patients in the Hospital Universiti Kebangsaan Malaysia (HUKM). Bioelectrical impedance measurements were conducted on 83 (47 males and 36 females) serologically confirmed dengue fever (DF) and dengue hemorrhagic fever (DHF) patients during their hospitalization. The predictive equation for Hb was derived using multivariate analysis. We investigated all the parameters in BIA, patients' symptom and demographic data. In this developed model, four predictors (reactance (Xc), sex, weight and vomiting) were found to be the best predictive factors for modeling Hb in dengue patients. However, …
