The Story of the Texas Pain Society: Formation and Function of a Regional Pain Society

Abstract: The idea of forming a Texas Pain Society came to the Founders in 1987 due to disparity and deficiencies in the practice of pain management in the United States and, in particular, the State of Texas. The Founders considered very carefully the implication of forming such a society. They diligently mapped out the mission and goals of the Texas Pain Society in those early formative years. This report is the history of Texas Pain Society as the activities unfolded from 1989 to 2011. The reader may question why there is a need to tell such a story. We believe strongly that, with disparities of standards of practice in pain medicine and poor recognition of advances in pain management, this scenario is quite common in many states and countries. The practitioners of pain management in these regions certainly must have considered getting together and forming a consensus on the standards of practice in their communities. This historical report of the Texas Pain Society provides the relevant information necessary and the efforts to be made for a society’s mission to achieve its goals and have an ongoing impact in its own region. We hope that we have shed some light on a process for the formation of a regional pain society such as ours. ?     

Home collection for frequent HIV testing: acceptability of oral fluids, dried blood spots and telephone results. HIV Early Detection Study Group

OBJECTIVE: To assess the feasibility and acceptability of bimonthly home oral fluid (OF) and dried blood spot (DBS) collection for HIV testing among high-risk individuals. DESIGN: A total of 241 participants [including men who have sex with men (MSM), injecting drug users (IDU), and women at heterosexual risk] were recruited from a randomly selected subset of study participants enrolled at four sites in the HIV Network for Prevention Trials (HIVNET) cohort, and assigned at random to bimonthly home collection of OF or DBS specimens over a 6 month interval. Participants could select telephone calls or clinic visits to receive HIV test results. METHODS: Bimonthly specimens were tracked for adherence to the schedule, were evaluated for adequacy for testing, and tested using antibody assays and polymerase chain reaction (PCR) for DBS. The acceptability of bimonthly home OF and DBS collection and telephone counseling was assessed in an end-of-study questionnaire. RESULTS: The laboratory received 96 and 90% of expected OF and DBS specimens, respectively; 99% of each specimen type was adequate for testing. Almost all (95%) participants chose results disclosure by telephone. The majority of participants (85%) reported that bimonthly testing did not make them worry more about HIV, and almost all (98%) judged that with bimonthly testing their risk behavior remained the same (77%) or became less risky (21%). CONCLUSION: Bimonthly home specimen collection of both OF and DBS with telephone counseling is acceptable and feasible among study participants at high risk. These methods will be useful for the early detection of HIV infection and remote follow-up of research cohort participants in HIV vaccine and prevention trials.     

Acquired deficit of forebrain glucocorticoid receptor produces depression-like changes in adrenal axis regulation and behavior

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is a hallmark of major depressive disorder. A number of studies have shown that this dysregulation is correlated with impaired forebrain glucocorticoid receptor (GR) function. To determine whether a primary, acquired deficit in forebrain GR signaling is an etiologic factor in the pathogenesis of depression, we generated a line of mice with time-dependent, forebrain-specific disruption of GR (FBGRKO). These mice develop a number of both physiological and behavioral abnormalities that mimic major depressive disorder in humans, including hyperactivity of the HPA axis, impaired negative feedback regulation of the HPA axis and, increased depression-like behavior. Importantly, a number of these abnormalities are normalized by chronic treatment with the tricyclic antidepressant, imipramine. Our findings suggest that imipramine's proposed activities on forebrain GR function are not essential for its antidepressant effects, and that alteration in GR expression may play a causative role in disease onset of major depressive disorder.     

Outcome of hepatitis B virus infection in homosexual men and its relation to prior human immunodeficiency virus infection.

To investigate the effect of human immunodeficiency virus type 1 (HIV-1) infection on subsequent hepatitis B virus (HBV) infection, HIV antibody was sought in homosexual men who developed HBV infection during a hepatitis B vaccine trial. Among 134 unvaccinated HIV-1-negative men, 7% became HBV carriers, 64% had viremia, and 42% had clinical illness. Among vaccinated HIV-1-negative men, HBV infection severity decreased with number of vaccine doses administered. When adjusted for prior hepatitis B vaccination status, persons with HIV-1 infection preceding HBV infection had a significantly higher risk of developing HBV carriage, viremia, prolonged ALT elevation, and clinical illness. Among HIV-1-infected men, the risk of HBV carriage was increased in unvaccinated persons (21%) and those who failed to respond to vaccination (31%) and further increased in those who received vaccine doses at the time they developed new HBV infection (56%-80%), suggesting inactivated hepatitis B vaccine may temporarily impair the immune response to HBV infection in HIV-1-infected persons. HIV-1 infection was also associated with reduced alanine aminotransferase elevations during the first 36 months of follow-up of men who became HBV carriers.     

A 62-dose, 6-month therapy for pulmonary and extrapulmonary tuberculosis. A twice-weekly, directly observed, and cost-effective regimen

STUDY OBJECTIVE: To evaluate the efficacy and toxicity of a 62-dose, four-drug, 6-month, and directly observed regimen for treatment of pulmonary and extrapulmonary tuberculosis. DESIGN: An open, nonblinded clinical trial, with intended follow-up of patients for 36 months after the completion of therapy. SETTING: A metropolitan tuberculosis clinic in a public health department. PATIENTS: From March 1981 through April 1989, we enrolled 160 patients with suspected or known tuberculosis; 35 of these patients were excluded from the analysis. INTERVENTIONS: Isoniazid, rifampin, pyrazinamide, and streptomycin were administered daily for 2 weeks; these drugs were then given in higher doses twice weekly for 6 weeks, followed by isoniazid and rifampin twice weekly for 6 weeks, followed by isoniazid and rifampin twice weekly for 18 weeks. A total of 62 doses were administered, and all therapy was directly observed by a nurse or an outreach worker. MEASUREMENTS AND MAIN RESULTS: Of the 125 evaluable patients, 101 (81%) had pulmonary tuberculosis, 7 (6%) had both pulmonary and extrapulmonary involvement, and 17 (13%) had extrapulmonary disease only. Seventy-one (57%) patients had a history of recent alcoholism. There were two relapses (1.6% +/- 2.2%), occurring 6 and 56 months after the completion of therapy. The time at which sputum samples became culture negative in pulmonary patients ranged from 1 to 19 weeks (median, 4.6 weeks); 40% +/- 9.6% of patients were culture-negative after 4 weeks of therapy, 75% +/- 8.5% after 8 weeks, 94% +/- 4.7% after 12 weeks, 97% +/- 3.3% after 16 weeks, and 100% after 20 weeks. Adverse drug reactions included hyperuricemia (greater than 178 mumol/L [3 mg/dL] above normal) secondary to pyrazinamide in 80 patients (64%), twofold or greater elevations of aspartate aminotransferase in 21 patients (17%), 1.5-fold or greater elevations of alkaline phosphatase in 33 patients (27%), cutaneous abnormalities in 8 patients (6%), nausea in five patients (4%), and dizziness in 1 patient (1%). CONCLUSIONS: This 62-dose, largely twice-weekly tuberculosis treatment regimen is efficacious and relatively nontoxic and is especially useful for patients in whom directly observed therapy is indicated.     

Predictors of Survival in Sinonasal Adenocarcinoma

Objectives To identify factors associated with disease-specific survival (DSS) in intestinal and nonintestinal sinonasal adenocarcinoma. Design Retrospective review. Setting Surveillance Epidemiology and End Results database. Participants Adult patients with sinonasal adenocarcinoma. Main Outcome Measures DSS. Results We identified 325 patients; of these, 300 had the nonintestinal type and 25 had intestinal type histologies. The 5-year DSS rates for patients who had no treatment, radiation (RT), surgery, and surgery and postoperative RT were 42.5, 46.1, 85.6, and 72.6%, respectively (log-rank test; p < 0.001). Black race, age ≥ 75 years, paranasal sinus involvement, and high grade were independently associated with decreased DSS. Compared with RT, surgery (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.15–0.77), and adjuvant RT (HR: 0.47; 95% CI, 0.26–0.86) were associated with improved DSS. Conclusions There is no difference in prognosis between intestinal and nonintestinal subtypes of sinonasal adenocarcinoma. Treatment with surgery alone or adjuvant RT is associated with a more favorable prognosis.
