Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) in response to the World Trade Center (WTC) disaster of 11 September 2001 (9/11) is one of the most prevalent and persistent health conditions among both professional (e.g. police) and non-traditional (e.g. construction worker) WTC responders, even several years after 9/11. However, little is known about the dimensionality and natural course of WTC-related PTSD symptomatology in these populations. METHOD Data were analysed from 10 835 WTC responders, including 4035 police and 6800 non-traditional responders who were evaluated as part of the WTC Health Program, a clinic network in the New York area established by the National Institute for Occupational Safety and Health. Confirmatory factor analyses (CFAs) were used to evaluate structural models of PTSD symptom dimensionality; and autoregressive cross-lagged (ARCL) panel regressions were used to examine the prospective interrelationships among PTSD symptom clusters at 3, 6 and 8 years after 9/11. RESULTS CFAs suggested that five stable symptom clusters best represent PTSD symptom dimensionality in both police and non-traditional WTC responders. This five-factor model was also invariant over time with respect to factor loadings and structural parameters, thereby demonstrating its longitudinal stability. ARCL panel regression analyses revealed that hyperarousal symptoms had a prominent role in predicting other symptom clusters of PTSD, with anxious arousal symptoms primarily driving re-experiencing symptoms, and dysphoric arousal symptoms primarily driving emotional numbing symptoms over time. CONCLUSIONS Results of this study suggest that disaster-related PTSD symptomatology in WTC responders is best represented by five symptom dimensions. Anxious arousal symptoms, which are characterized by hypervigilance and exaggerated startle, may primarily drive re-experiencing symptoms, while dysphoric arousal symptoms, which are characterized by sleep disturbance, irritability/anger and concentration difficulties, may primarily drive emotional numbing symptoms over time. These results underscore the importance of assessment, monitoring and early intervention of hyperarousal symptoms in WTC and other disaster responders.

Abstract
BACKGROUND Longitudinal symptoms of post-traumatic stress disorder (PTSD) are often characterized by heterogeneous trajectories, which may have unique pre-, peri- and post-trauma risk and protective factors. To date, however, no study has evaluated the nature and determinants of predominant trajectories of PTSD symptoms in World Trade Center (WTC) responders. METHOD A total of 10835 WTC responders, including 4035 professional police responders and 6800 non-traditional responders (e.g. construction workers) who participated in the WTC Health Program (WTC-HP), were evaluated an average of 3, 6 and 8 years after the WTC attacks. RESULTS Among police responders, longitudinal PTSD symptoms were best characterized by four classes, with the majority (77.8%) in a resistant/resilient trajectory and the remainder exhibiting chronic (5.3%), recovering (8.4%) or delayed-onset (8.5%) symptom trajectories. Among non-traditional responders, a six-class solution was optimal, with fewer responders in a resistant/resilient trajectory (58.0%) and the remainder exhibiting recovering (12.3%), severe chronic (9.5%), subsyndromal increasing (7.3%), delayed-onset (6.7%) and moderate chronic (6.2%) trajectories. Prior psychiatric history, Hispanic ethnicity, severity of WTC exposure and WTC-related medical conditions were most strongly associated with symptomatic trajectories of PTSD symptoms in both groups of responders, whereas greater education and family and work support while working at the WTC site were protective against several of these trajectories. CONCLUSIONS Trajectories of PTSD symptoms in WTC responders are heterogeneous and associated uniquely with pre-, peri- and post-trauma risk and protective factors. Police responders were more likely than non-traditional responders to exhibit a resistant/resilient trajectory. These results underscore the importance of prevention, screening and treatment efforts that target high-risk disaster responders, particularly those with prior psychiatric history, high levels of trauma exposure and work-related medical morbidities.

Abstract
The objective of this article is to examine the relationship between panic attacks, panic disorder, and suicidal ideation among primary care patients. A probability sample of 1,007 primary care attenders from a large urban university practice was assessed for current mental disorders and suicidal ideation (past 2 week prevalence) with the PRIME-MD Patient Health Questionnaire. Controlling for major depression, substance use disorders, and sociodemographic variables simultaneously, patients with either panic attacks or panic disorder had significantly increased risks of suicidal ideation. Suicidal ideation was highly associated with major depression and comorbid panic disorder (OR = 15.4) or panic attacks (OR = 7.9). There is need for detection and possible treatment of patients with panic attacks or disorder in primary care, especially among those with co-occurring major depression.

Abstract
The authors investigated the prevalence of multiple medically unexplained symptoms (MMUS) as identified by primary care physicians (PCPs) in a systematic sample of 172 patients. Patients were from a university-affiliated urban primary care practice serving a low-income population. Patients with a history of MMUS were older (mean: 57.2 vs. 53.0 years), more likely to be female (90.5% vs. 72.3%), and less likely to be married or living with a partner (14.4% vs. 36.2%) than those without MMUS. Patients with MMUS had over twice the rate of any current psychiatric disorder, almost two-and-a-half times the rate of any current anxiety disorder, and greater functional impairment. These data suggest that patients with MMUS are as common in urban primary care clinics as in more affluent clinics and reinforce the need for PCPs to screen these patients for common and treatable psychiatric conditions.

Abstract
OBJECTIVE Assessment of functional status is increasingly important in clinical trials and outcome research. Although several scales for assessing functioning are widely used, they vary in coverage, and direct comparisons among them are rare. Comparative information is useful in guiding selection of appropriate scales for research applications. METHOD Results from three scales that measure functioning-the Medical Outcomes Study 36-item Short-Form Health Survey, the Social Adjustment Scale Self-Report, and the Social Adaptation Self-Evaluation Scale-were compared in a consecutively selected sample of 211 patients coming to primary care. Patients also received psychiatric assessments. RESULTS All three scales were acceptable to patients, showed few significant correlations with demographic variables, and were able to differentiate psychiatrically ill and well patients. Correlations among scales, even among scale items that assessed similar domains of functioning, were modest. CONCLUSIONS Although all three scales are presumed to assess functional status, their item content and coverage differ. Selection of a scale requires a review of the scale items and consideration of research priorities and the characteristics of the study group. If functional status is a critical outcome measure, use of more than one scale may be necessary.

Abstract
BACKGROUND Most research on the prevalence of mental disorders in primary care has been conducted in practices that serve middle- and upper-income patients. OBJECTIVE To determine the prevalence of major mental disorders in a primary care practice that serves a predominantly low-income immigrant patient population. DESIGN Cross-sectional survey; criterion standard. SETTING Urban general medicine practice. PARTICIPANTS Systematic sample of consecutive adult patients with scheduled appointments. Of 1266 approached eligible patients, 1007 (80%) participated. MAIN OUTCOME MEASURES PRIME-MD Patient Health Questionnaire major depression, generalized anxiety disorder, panic disorder, alcohol use disorder, and suicidal ideation; drug use disorder; functional status; work loss; family distress; and mental health treatment. RESULTS Major depression (18. 9%), generalized anxiety (14.8%), panic (8.3%), and substance use (7. 9%) disorders and suicidal ideation (7.1%) were highly prevalent. Many patients had more than 1 disorder (range, 36.3% [substance use disorder] to 76.9% [panic disorder]). In multivariate analyses, each disorder was significantly associated with an increase in impairment after controlling for demographic characteristics, perceived health, and the other disorders. A minority of patients with each disorder (range, 22.5% [substance use disorder] to 46.4% [panic disorder]) reported receiving mental health treatment in the last month. CONCLUSIONS Clinically significant depression, anxiety, substance use, and suicidal ideation are quite common in this practice and associated with significant functional impairment. Primary care practices that serve poor urban immigrant populations have a critical need to provide access to mental health services. Arch Fam Med. 2000;9:876-883

Abstract
Nodular regenerative hyperplasia was found in nine patients who had hematological disease including polycythemia vera, agnogenic myeloid metaplasia, primary thrombocythemia, rheumatoid arthritis with thrombocytosis, multiple myeloma, and erythrocytosis associated with polycystic renal disease. Portal hypertension was suspected in three and features of hypersplenism were present in four. 2. Nodular regenerative hyperplasia occurred in livers which had widespread obliteration of portal vein radicals (obliterative portal venopathy). Morphometric analysis indicated that the portal vein lesions were predominately located in veins up to 0.2 mm in diameter and were significantly more frequent than similar lesions occurring in elderly persons. 3. The following pathogenesis of nodular regenerative hyperplasia is proposed: Thrombi, perhaps largely composed of platelet aggregates formed in the portal venous circulation or spleen, embolize to the liver and results in obliterative vascular lesions. Atrophy and regenerative nodule formation occur in response to the interruption of the portal blood supply.
