A prospective study of tender points and fibromyalgia during and after an acute viral infection.

BACKGROUND: Tender points (TPs) and fibromyalgia (FM) may be precipitated by infections, but the frequency, associated characteristics, and predictors of these outcomes are unknown. OBJECTIVES: To determine if acute infectious mononucleosis (AIM) is associated with the development of TPs or FM acutely or during the subsequent 6 months; if demographic, clinical, or psychosocial features predict TPs or FM; and if TPs or FM correlate with nonrecovery. METHODS: A total of 150 subjects diagnosed as having AIM were assessed with physical examinations (including palpation of 18 TPs), laboratory tests, and measures of psychosocial and somatic functioning at enrollment and at 2 and 6 months. Subjects also completed a structured psychiatric interview at the initial evaluation. RESULTS: At presentation and at 2 and 6 months, the mean TP counts were 7.5, 4.6, and 3.0, respectively; at these time points, 19%, 3%, and 1% of subjects also met modified criteria for FM. Tender points and degree of pain diminished over time following AIM. Acutely, TPs were associated only with higher temperature (P<.001). Baseline features that predicted more TPs at 2 and 6 months were female sex, older age, less family social support, and more TPs at presentation. Neither initial laboratory tests nor psychiatric disease or distress predicted TPs. Differences between those who had and had not recovered at 6 months were found for the mean number of TPs (P<.008), the proportion of subjects with 11 or more TPs (P<.002), and the degree of pain. CONCLUSIONS: Tender points are a common, transient finding associated with AIM, but FM is an unusual long-term outcome. Demographic, social, and physical examination features predicted TPs.

Roscovitine induces cell death and morphological changes indicative of apoptosis in MDA-MB-231 breast cancer cells.

We have previously shown (Mgbonyebi et al., Anticancer Res., 18: 751-756, 1998) that roscovitine, an olomoucine-related purine analogue and a selective inhibitor of cyclin-dependent kinases, inhibited the proliferative activity of human breast epithelial cells in vitro. The purpose of the present study was to identify the cellular processes and targets affected by roscovitine treatment in the estrogen receptor-negative MDA-MB-231 human breast carcinoma cells. Treatment of the cells with 10 microg/ml roscovitine daily for a length of time ranging from 24 to 240 h revealed that the compound inhibited DNA synthesis, induced cell death, and irreversibly inhibited the proliferative activity of the cells. Morphological analysis of roscovitine-treated cells by light and fluorescence microscopy demonstrated that this cyclin-dependent kinase inhibitor induced cell shrinkage, chromatin condensation, reorganization of actin microfilament architecture, and extensive detachment of cells from the cell culture substratum. These cellular events are all known to be associated with apoptosis. Collectively, the data generated from this study suggest that roscovitine induced apoptosis in the estrogen receptor-negative MDA-MB-231 human breast cancer cells. Because the efficacy of many anticancer drugs depends on their ability to induce apoptotic cell death, modulation of this parameter by roscovitine may provide a new chemopreventive and chemotherapeutic strategy for the clinical management of hormone-resistant breast cancers.

Stepped collaborative care for primary care patients with persistent symptoms of depression: a randomized trial.

BACKGROUND: Despite improvements in the accuracy of diagnosing depression and use of medications with fewer side effects, many patients treated with antidepressant medications by primary care physicians have persistent symptoms. METHODS: A group of 228 patients recognized as depressed by their primary care physicians and given antidepressant medication who had either 4 or more persistent major depressive symptoms or a score of 1.5 or more on the Hopkins Symptom Checklist depression items at 6 to 8 weeks were randomized to a collaborative care intervention (n = 114) or usual care (n = 114) by the primary care physician. Patients in the intervention group received enhanced education and increased frequency of visits by a psychiatrist working with the primary care physician to improve pharmacologic treatment. Follow-up assessments were completed at 1, 3, and 6 months by a telephone survey team blinded to randomization status. RESULTS: Those in the intervention group had significantly greater adherence to adequate dosage of medication for 90 days or more and were more likely to rate the quality of care they received for depression as good to excellent compared with usual care controls. Intervention patients showed a significantly greater decrease compared with usual care controls in severity of depressive symptoms over time and were more likely to have fully recovered at 3 and 6 months. CONCLUSIONS: A multifaceted program targeted to patients whose depressive symptoms persisted 6 to 8 weeks after initiation of antidepressant medication by their primary care physician was found to significantly improve adherence to antidepressants, satisfaction with care, and depressive outcomes compared with usual care.

Microsatellite instability during the immortalization and transformation of human breast epithelial cells in vitro.

The objective of this study was to determine whether microsatellite instability (MSI) and loss of heterozygosity (LOH) are involved in the immortalization of human breast epithelial cells (HBECs) in vitro and in the early stages of their transformation by benzo[a]pyrene (BP) and 7,12-dimethylbenz[a]anthracene (DMBA). We performed a genome-wide analysis of a total of 466 microsatellite DNA polymorphism loci along the X chromosome and the 22 pairs of human autosomes. MSI was found in the immortalized MCF-10F cells at the following loci: D11S1392 (on chromosome 11p13) and D17S849 (at 17p13.3), D17S796 (at 17p13.1), D17S513 (at 17p13.1), TP53 (at 17p13.1), D17S786 (at 17p13.1), and D17S520 (at 17p12) on chromosome 17. The BP-transformed cells exhibited MSI in the same loci and also in locus D11S912 (at 11q25). The more transformed BP1E cells also exhibited MSI on chromosome 13q12-13 at D13S260 and D13S289, markers known to flank the breast cancer susceptibility gene BRCA2. In the DMBA-transformed D3 and D3-1 cells, MSI was observed at the locus D13S260 in addition to the previously reported locus D16S285 (at 16q12.1). No LOH was observed on any of the chromosomes tested in these cells. These observations led us to conclude that the immortalization and transformation of HBECs may involve defects in mechanisms responsible for the cell's genomic stability, such as DNA replication and DNA mismatch repair.

Inhibition of rat mammary tumorigenesis by human chorionic gonadotropin associated with increased expression of inhibin.

This work was designed to test whether the suppression of 7,12-dimethylbenz[a]anthracene (DMBA)-induced rat mammary carcinomas by human chorionic gonadotropin (hCG) is associated with the synthesis of inhibin. For this purpose, virgin rats received 8 mg DMBA/100 g body weight; 20 d later they were injected daily with 100 IU of hCG for 40 d (DMBA+hCG group). Age-matched untreated (control), hCG-, and DMBA+saline-treated rats were used for comparisons. Mammary tissues were collected for histopathological and mRNA analyses after 5, 10, 20, and 40 d of hCG injection and 20 d after treatment. None of the animals in the control and hCG-treated groups developed mammary tumors. DMBA-treated rats developed a high incidence of both microscopic lesions, i.e., intraductal proliferations and ductal carcinomas in situ, and palpable tumors. In DMBA+hCG-treated rats, the incidence of microscopic and palpable tumors was markedly reduced. In these animals, alpha- and beta-inhibin immunoreactivity was elevated in the non-tumoral mammary glands in association with lobule formation and in the tumors. Inhibin A and B mRNAs were also elevated in the mammary tissue, and c-myc and c-jun were induced by the hormonal treatment. DMBA alone did not modify the expression of these genes. Our findings indicate that inhibin production and gene activation are associated with both mammary gland differentiation and tumor regression.

RNA relocation at mitosis in transformed and tumorigenic human breast epithelial cells.

The fate of RNA revealed by metachromatic staining after a critical electrolyte concentration assay using toluidine blue and Mg(2+)ions as competitors for the substrate dye binding sites was followed at mitosis in human breast epithelial cells transformed by benzo[a]pyrene and transfected with the c-Ha- ras oncogene. The aim was to detect changes in RNA distribution during mitosis in human transformed/tumorigenic cells exhibiting increased nucleolar sizes and rRNA production while in interphase. RNA relocation in association with the mitotic spindle fibers was observed from metaphase to telophase not to vary in all the cell lines studied. RNA-containing nucleolus-like bodies persistent during mitosis were found to decrease in frequency in the transformed and tumorigenic cells in comparison with control non-transformed cells simultaneously to the previously reported increase in nucleolar areas for the same cells while in interphase. It is suggested that an improved use of RNA transcripts has been developed with cell transformation and tumorigenesis in this particular model.

Plasma lipid concentrations during episodic occupational stress.

The possibility that stress affects plasma lipid concentrations has been the subject of recent investigation, but the findings are equivocal in nonlaboratory settings. To determine whether psychological stress contributes to variability in plasma lipid concentrations and concomitant changes in health behaviors, the effect of increased work load on plasma lipids and apolipoproteins was examined in 173 lawyers. Plasma cholesterol, triglyceride, and apolipoprotein concentrations were studied during periods of high work load (corresponding to impending tax deadlines) and during periods of usual work load. Self-reports of stress, work load, and time pressure, and cortisol, blood pressure, and heart rate were measured to verify that impending deadlines were associated with increased stress levels. Health behaviors which may affect plasma lipoprotein concentrations, including dietary intake and exercise, were also examined. High work load was accompanied by increases in self-reported work load among lawyers most directly affected by the impending deadlines. Plasma apolipoprotein B and triglycerides increased during periods of high work load (M = 1.9 mg/dL, SD = 10.1 and M = 5.3, SD = 34.4, respectively). No changes in dietary intake and exercise were observed. Psychological stress (high work load) is associated with potentially atherogenic changes in plasma lipid concentrations. While the lipoprotein effect of this short-term work stress is small, the effects of longer-term stress on multiple rise factors including triglycerides and apolipoprotein B could have significance for the development of coronary artery disease.

Adult health status of women with histories of childhood abuse and neglect.

PURPOSE: Several recent studies have found associations between childhood maltreatment and adverse adult health outcomes. However, methodologic problems with accurate case determination, appropriate sample selection, and predominant focus on sexual abuse have limited the generalizability of these findings. SUBJECTS AND METHODS: We administered a survey to 1,225 women who were randomly selected from the membership of a large, staff model health maintenance organization in Seattle, Washington. We compared women with and without histories of childhood maltreatment experiences with respect to differences in physical health status, functional disability, numbers and types of self-reported health risk behaviors, common physical symptoms, and physician-coded ICD-9 diagnoses. RESULTS: A history of childhood maltreatment was significantly associated with several adverse physical health outcomes. Maltreatment status was associated with perceived poorer overall health (ES = 0.31), greater physical (ES = 0.23) and emotional (ES = 0.37) functional disability, increased numbers of distressing physical symptoms (ES = 0.52), and a greater number of health risk behaviors (ES = 0.34). Women with multiple types of maltreatment showed the greatest health decrements for both self-reported symptoms (r = 0.31) and physician coded diagnoses (r = 0.12). CONCLUSIONS: Women with childhood maltreatment have a wide range of adverse physical health outcomes.

Pattern of distribution of cells positive for estrogen receptor alpha and progesterone receptor in relation to proliferating cells in the mammary gland.

Since cell proliferation is indispensable for the growth and development of the breast, and estrogens are considered to play a major role in promoting cell proliferation, while progesterone influences its differentiation, the present work was designed with the purpose of verifying the relationship between cells containing steroid hormone receptors and proliferating cells in the normal human breast. Twelve breast samples were analyzed for their content of lobules type 1 (Lob1), Lob2, Lob3, and Lob4, and the number of cells containing estrogen receptor alpha (ER-alpha), progesterone receptor (PgR), or expressing Ki67 antibody was determined by double immunocytochemical technique with specific antibodies. The highest percentage of ER-alpha, PgR, and Ki67 positive cells was found in Lob1, with a progressive reduction in the more differentiated Lob2 and Lob3. ER-alpha and PgR positive cells were found exclusively in the breast epithelium and were negative for Ki67, while cells positive for Ki67 did not express receptors. These findings were compared with the distribution of ER-alpha and PgR in the autoradiographs of mammary gland of young virgin rats inoculated with 3H-thymidine for determination of the DNA labeling index (DNA-LI). Both the DNA-LI and the percentage of ER-alpha and PgR positive cells were maximal in the epithelium of terminal end buds, and these values were reduced in alveolar buds and lobules. ER-alpha and PgR positive cells did not proliferate, and those cells that had incorporated 3H-thymidine were negative for both receptors. Our results led us to conclude that the content of ER-alpha and PgR in the normal mammary tissue varies with the degree of lobular development, in parallel with cell proliferation. However, the expression of receptors occurs in cells other than the proliferating cells, indicating that they represent at least two separate cell populations. These findings open new avenues towards the understanding of the mechanisms through which estrogens and progesterone affect the proliferative activity of breast epithelial cells, and their role in the initiation of the cascade of events that leads a normal cell to cancer.

Patterns of care for depressed older adults in a large-staff model HMO.

The authors examined automated pharmacy and visit data for 502 members of a large-staff model health maintenance organization (HMO) who had been diagnosed with depression and started on antidepressants by their primary-care providers. Older patients (age >/=60; n=110) were less likely than younger adults (age 18-59, n=110) to receive adequate doses of antidepressant medications for 30 or 90 days. Older adults were also less likely than younger adults to receive more than two primary-care visits for depression in the 12 weeks after receiving a new antidepressant prescription and were less likely to receive specialty mental health care in the 6 months after receiving a new antidepressant prescription.

Validity and responsiveness of the Minimum Data Set.

OBJECTIVE: To determine the criterion validity and responsiveness to change over time of the Minimum Data Set (MDS). DESIGN: Cross sectional analysis comparing prospectively collected research data with MDS data reported from nursing homes on identical subjects. Longitudinal follow-up of subjects allowed for calculation of responsiveness to change over time. PARTICIPANTS: Subjects (n = 140) participating in epidemiological research on the natural history of Alzheimer's disease in the University of Washington Group Health Cooperative Alzheimer's Disease Patient Registry (ADPR) who entered nursing homes in Washington State from January 1990 through March 1996. MAIN OUTCOME MEASUREMENTS: Spearman's correlation coefficients to compare MDS cognitive performance scale scores with Mini-Mental State Examinations (MMSE), MDS behavior domain scores with ADPR Physician Behavior checklist scores, and MDS activities of daily living (ADL) functioning scores with Dementia Rating Scale scores for ADLs. Partial correlations were used to control for the number of days between MDS and ADPR assessments, age, and function in the other two MDS ratings of ADL, cognition, or behavior. We determined responsiveness by using the mean change in an effect size (ES) calculation for each domain of interest. RESULTS: MDS measures in all three domains were correlated modestly to the analogous ADPR research instruments, with correlation coefficients 0.45 for cognition, 0.50 for behavior, and 0.59 for ADL functioning. Controlling for age, time between ADPR and MDS assessments, and the MDS ratings of the other two MDS domains did not improve the correlations significantly. In a subgroup of 60 subjects followed for an average of 636 days, the Cognitive performance scale of the MDS had a slightly larger effect size (ES = 0.60) than the Folstein Mini-Mental Status Exam (ES = 0.39) used by the ADPR. However, the Dementia Rating Scale (ES = 0.77) used by the ADPR researchers reflected more change over time than the ADL domain of the MDS (ES = 0.02). The MDS behavior domain (ES = 0.058) was comparable to the research behavior checklist (ES = 0.065). CONCLUSIONS: These data demonstrate reasonable criterion validity of the MDS and the MMSE, ADL, and behavior rating scales and suggest that the MDS data is of adequate validity for research purposes in these areas. The MDS was less able to capture dementia-related change in ADLs in this population of patients with dementia even though the same nursing home staff completing the MDS often supplied the information for completing the research scales. As a result, the MDS may be limited as an outcome assessment instrument.

Ha-ras oncogene effect on DNA content and chromatin supraorganization in benzo[a]pyrene-transformed human breast epithelial cells.

When transfected to benzo[a]pyrene (BP)-transformed MCF-10F human breast epithelial cells (BP1 cell line) the c-Ha-ras oncogene has proven to enhance the neoplastic changes initiated by exposure to BP, giving rise to an aggressive tumorigenic cell line, BP1-Tras. We have previously demonstrated by image analysis that BP affects the DNA content and the chromatin supraorganization of MCF-10F cells. Here Feulgen-stained BP1-Tras cells were studied by image analysis in order to evaluate possible additional changes in DNA content and chromatin texture induced by insertion of the ras oncogene. A high variability in DNA content also including polyploidy or near-polyploidy, and an increase in the packing states of the chromatin which became still condensed in BP1 cells were found in BP1-Tras cells. The results differed from those reported for the BP1-E1 cell line which is also an aggressive tumorigenic cell line, but was attained through progressive passages of BP-transformed cells. It was demonstrated that different patterns of changes in DNA content and chromatin organization may be involved in equally aggressive tumorigenic BP-transformed cell lines originated from the same cell line by different mechanisms.

Species, interindividual, and tissue specificity in endocrine signaling.

The activity of endocrine-active agents exhibits specificity at many levels. Differential responsiveness to these agents has been observed between different species and extends to interindividual differences within a species and between different tissues as well. In cases where they have been identified, the biologic and molecular mechanisms underlying this specificity are quite diverse. Determinants of species specificity include differences that exist in receptor binding, gene transcription, and cellular responses to endocrine-active compounds between species. Interindividual differences in responsiveness may be determined at the level of genetic polymorphisms in hormone-metabolizing enzymes, hormone receptors, and in those genes that are transactivated by these receptors, as well as during changing windows of susceptibility that occur as a function of age, such as prenatal and postmenopausal exposures. Extrinsic factors such as diet can also impact individual susceptibility to endocrine-active agents. Tissue-specific determinants of susceptibility are well documented, but little is known regarding the mechanisms underlying these different responses. Differences in the expression of accessory proteins for steroid hormone receptors and different patterns of receptor expression, estrogen receptor alpha and estrogen receptor beta; for example, may contribute to tissue specificity, as may differences in the pattern of expression of other genes such as hormone-metabolizing enzymes. The use of animal model systems and development of appropriate mathematical models has the potential to yield additional valuable information for elucidating the role of these determinants of specificity at low-dose exposures and for improved risk assessments for the adverse health effects of endocrine-active compounds.

Functional roles of chromosomes 11 and 17 in the transformation of human breast epithelial cells in vitro.

Genomic alterations in primary breast cancer play a role in the initiation and progression of the disease. We have analyzed the molecular events involved in the initiation and progression of the neoplastic process in an in vitro experimental system. Immortalization of human breast epithelial cells (HBEC) is associated with 3:9 translocation, p53 mutation and microsatellite instability (MSI) of chromosomes 11p13, and 17p. BP1-E cells, derived from the immortalized MCF-10F cells transformed by the carcinogen benzo(a)pyrene (BP), express in vitro growth advantage, anchorage independence, enhanced chemoinvasiveness, loss of ductulogenic capabilities and tumorigenesis in a heterologous host. This neoplastic progression is also associated with mutations and/or amplification of c-H-ras, int-2, c-neu, c-myc and MDM2, MSI at 11q25 and 13q12-q13 and loss of heterozygosity at 17p. In order to test whether chromosomes 11 or 17 play a functional role in the phenotypic expression of transformation of BP1E cells, we utilized microcell-mediated chromosome transfer (MMCT) technique for inserting the corresponding normal chromosomes to these transformed cells. BP1E cells were transfected with PsV2neo plasmid and fused with microcells obtained from the mouse cell line A9, containing a normal chromosome 11 or 17 (A9-11neo and A9-17neo cells, selected in G418 and cloned. Sixteen primary microcell hybrids from each chromosome transfer, designated BP1E-11neo and BP1E-17neo survived selection in G-418 containing medium. A single clone from each group, BP1E-11neo #145 and BP1E-17neo D100, survived subcloning and were utilized for a detailed panel of analyses. The presence of a donor chromosome was confirmed by dual color fluorescence in situ hybridization (FISH), southern blot analysis of the marker vector pSV2neo, and microsatellite polymorphism analysis. The transfer of the normal chromosomes 11 and 17 resulted in a 50% and 90% inhibition of cell growth respectively, and reduced both colony efficiency and colony size. Telomerase activity was significantly reduced only by chromosome 17 insertion, providing a possible explanation for the more significant senescence observed in BP1E-17neo D100 cells. Microsatellite polymorphism analysis revealed that three loci, 11q13-23, 11q23.1, and 11q23.3 (markers D11S911, DRD2, and D11S29) were retained in BP1E-11neo #145 cells, and two, 17q24.2-25.2, 17q25.2 (markers D17S515 and D17S785 were retained in BP1E-17neo D100 cells. We conclude that the specific regions of normal chromosomes 11 and 17 transferred play a functional role in the expression of immortal and transformed phenotypes of HBEC in vitro.

Allelic instability as a predictor of survival in Egyptian breast cancer patients.

This work was designed with the purpose of determining whether the presence of allelic imbalances (AI) such as microsatellite instability (MSI) and loss of heterozygosity (LOH) in chromosomes 2, 11, 13, and 17 in primary breast cancer could be used as prognostic indicators of patient survival. The DNA from breast cancers removed from 29 patients who were followed-up for up to five years was analyzed for MSI and LOH using a panel of 24 markers located at chromosome 2 (TPO, D2S131, D2S144, D2S171, D2S177, D2S119, D2S123, D2S147 and D2S136), chromosome 11 (C-RAS, Int-2, D11S940, D11S912), chromosome 13 (D13S289, D13S260, D13S267, D13S218, D13S263, D13S155, and D13S162), and chromosome 17 (D17S513, TP53, D17S855, and D17S785). The frequency of AI in the markers studied ranged from 30-55%, being highest for D11S912, D2S171, TP53 and D17S855. Univariate analysis showed association between overall survival rate and AI in 9 out of the 24 markers tested. Five of them were located at the area of the mismatch repair gene (MMR)-2 gene, two at 11p, one at 13q and one at 17p. Using multivariate analysis, it was observed that only pathological and clinical stage (defined as stage II or not) and AI at D2S171, D11S912, or D17STP53 generated significant predictive models for survival.

Antidepressant efficacy in HIV-seropositive outpatients with major depressive disorder: an open trial of nefazodone.

BACKGROUND: Treatment studies of major depression in patients who are seropositive for the human immunodeficiency virus (HIV) have shown comparable efficacy for both tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs). Nefazodone appears to be more tolerable than TCAs and similar to SSRIs. This study examined the efficacy and tolerability of nefazodone in an open 12-week trial of HIV-seropositive outpatients with major depressive disorder. METHOD: Fifteen HIV-seropositive patients with DSM-IV major depressive disorder and a 21-item Hamilton Rating Scale for Depression (HAM-D) score of > or =18 were treated with open-label nefazodone for 12 weeks. Hamilton Rating Scale for Anxiety, HAM-D, Clinical Global Impressions scale, and Systematic Assessment for Treatment Emergent Events general inquiry (for safety and tolerability) scores were obtained at weeks 2, 4, 6, 8, and 12. RESULTS: Of 15 patients receiving nefazodone, 4 discontinued treatment (1 for adverse effects). Of 11 patients who completed the trial, 8 (73%) were classified as full responders with a 50% reduction in HAM-D scores and final CGI score of 1 or 2, and 10 (91%) were classified as partial responders (only 50% reduction in HAM-D scores). Nefazodone-treated subjects experienced few total adverse effects (mean = 1.5), no sexual side effects, and low rates of adverse-effect-related dropout (1 subject, 7%). CONCLUSION: Depressed HIV-seropositive outpatients respond to nefazodone comparably to other outpatient populations and have few adverse effects, suggesting that nefazodone may have a role in the treatment of depression in HIV-seropositive patients. Potential drug interactions with protease inhibitors indicate that it is essential to evaluate for appropriate dosing to avoid adverse effects and increase overall antidepressant efficacy.

Panic disorder in the primary care setting: comorbidity, disability, service utilization, and treatment.

BACKGROUND: Increased medical service utilization in patients with panic disorder has been described in epidemiologic studies, although service use in primary care panic patients relative to other primary care patients is less well characterized. Inadequate recognition of panic has been shown in several primary care studies, although the nature of usual care for panic in this setting has not been well documented. This study aimed to document increased service use in panic patients relative to other primary care patients and to characterize the nature of their usual care for panic and their outcome. METHOD: Using a waiting room screening questionnaire and follow-up telephone interview with the Composite International Diagnostic Interview, we identified a convenience sample of 81 patients with panic disorder (DSM-IV) and a control group of 183 psychiatrically healthy patients in 3 primary care settings on the West Coast and determined psychiatric diagnostic comorbidity, panic characteristics, disability, and medical and mental health service use, including medications. A subsample (N = 41) of panic patients was reinterviewed 4-10 months later to determine the persistence of panic and the adequacy of intervening treatment received using the Harvard/Brown Anxiety Disorders Research Program study criteria for cognitive-behavioral therapy (CBT) and an algorithm developed by the authors for medications. RESULTS: Seventy percent of panic patients had a comorbid psychiatric diagnosis. Patients had more disability in the last month (days missed or cut down activities) (p < .01), more utilization of emergency room and medical provider visits (p < .01), and more mental health visits (p < .05). Despite the latter, only 42% received psychotropic medication, 36% psychotherapy, and 64% any treatment. On follow-up, 85% still met diagnostic criteria for panic, and only 22% had received adequate medication (type and/or dose) and 12% adequate (i.e., CBT) psychotherapy. CONCLUSION: These findings suggest a need for improved treatment interventions for panic disorder in the primary care setting to decrease disability and potentially inappropriate medical service utilization.
