The prevalence of symptomatic knee and distal interphalangeal joint osteoarthritis in the urban population of Antalya, Turkey.

The aim of this cross-sectional study was to estimate the prevalence and risk factors of symptomatic knee and distal interphalangeal (DIP) joint osteoarthritis (OA) in the elderly (> or =50 years of age) urban population of Antalya, Turkey. According to the 1997 national census, Antalya's population was 508,840. By random cluster sampling, 655 individuals aged 50 years or more were interviewed face-to-face and subjected to structured interviews regarding knee pain, worsening pain on exertion, and the gelling phenomenon. They were also asked about performing namaz (a fundamental act of worship in Islam performed five times a day), smoking, type of residence, type of toilet, work style, and duration of walking per day. They were also questioned about swelling in DIP joints. In the case of suspicion of knee OA, the individuals were invited to the hospital for further evaluation by physical examination and direct roentgenogram. The diagnosis of knee OA was based on clinical or clinical and radiographic findings. The prevalence of symptomatic knee OA was determined as 14.8% in the population aged 50 years or over. Advanced age, female sex, namaz, and type of residence were found to be associated with knee OA. The rate of symptomatic knee OA was significantly lower in smokers and those walking more than 2 h per day. Female sex was also strongly associated with OA DIP joints. OA of DIP joints was found significantly associated with symptomatic knee OA. The latter is a major health problem in the elderly population, especially in about one fourth of women aged 50 years or over. These data suggest that advanced age, female sex, and type of residence are risk factors.

Symptomatic spontaneous pneumothorax in term newborns.

The causes and risk factors of symptomatic spontaneous pneumothorax in term newborns are not completely understood. In the present study, our aim was to investigate the risk factors for and clinical and laboratory characteristics of term newborns with spontaneous symptomatic pneumothorax and to evaluate the outcome of management in this condition. A total of 11 term newborns admitted to the newborn intensive care unit with a diagnosis of symptomatic spontaneous pneumothorax were included during a 22-month period. Female to male ratio was 4:7, mean gestational age was 39.5 weeks, and 63% were delivered with a cesarean section, 18% of patients had renal and 55% had congenital cardiac anomalies. Rate of cardiac anomalies was more frequent in the study group compared to control group. Echocardiography in addition to renal ultrasonography may also be needed in term newborns with spontaneous symptomatic pneumothorax and further studies may be warranted to evaluate this association.

Diffusion-weighted MRI in patients with symptomatic internal carotid artery disease.

Beside the early detection of ischemia, there is an increasing body of evidence that diffusion-weighted imaging (DWI) can provide important information on stroke etiology. Against the background of an increased use of magnetic resonance angiography in patients being evaluated for carotid endarterectomy (CEA), the question arises if the additional performance of a DWI scan could also yield clinically relevant findings in these patients. In a prospective observational study we analysed the DWI data of 107 patients with high-grade symptomatic carotid artery disease (CAD) being evaluated for CEA. While no patient with a retinal TIA (n = 29) exhibited a DWI lesion, nineteen of the 42 patients with a hemisphere TIA and all patients with a minor stroke (n = 36) showed DWI lesion(s). In patients with TIAs the occurrence of DWI abnormalities was significantly more frequent in patients with long lasting TIAs. The majority of patients had multiple DWI lesions suggestive of acute large-artery thromboembolism as a common morphological phenotype of stroke. The finding of a similar lesion pattern in 4 patients with additional pre-existing atrial fibrillation suggested a symptomatic carotid stenosis. In contrast, unexpected bihemisphere lesions suggested cardioembolism in two patients with a normal circle of Willis and instigated thorough cardiac investigations. In both instances 24-h Holter monitoring revealed intermittent atrial fibrillation, so that a CEA was not performed. In conclusion, we demonstrate a common DWI lesion pattern in patients with symptomatic high-grade CAD eligible for CEA. In patients with known concomitant cardiac disorders the finding of this typical lesion pattern may support the diagnosis of a symptomatic CAD. In contrast, the additional performance of DWI can also reveal an unexpected cardiac source of embolism in some patients, which can substantially influence their further clinical management.

Gastrointestinal profile of symptomatic athletes at rest and during physical exercise.

Some athletes suffer from exercise-induced gastrointestinal (GI) disturbances. We developed a profile of GI parameters in 10 symptomatic and 10 asymptomatic athletes both at rest and during exercise. Exercise included 90 min of cycling and running at 70% of maximal power. We measured oesophageal motility, gastro-oesophageal reflux, gastric emptying, orocaecal transit time (OCTT), intestinal permeability and intestinal glucose absorption. During cycling the number and duration of refluxes were increased, whereas gastric emptying showed no differences between rest, cycling and running. The OCTT was increased in the running trial, compared to rest (P=0.005). Also, intestinal permeability was higher in the running trial, compared to rest (P=0.008). There were no differences in intestinal glucose absorption between rest and exercise. Compared with asymptomatic athletes the symptomatic subjects had a higher intestinal permeability (P=0.001), more reflux episodes (P=0.03) and a longer duration of reflux (P<0.05) during cycling. No differences were observed at rest. In conclusion, there is no difference in GI profile between symptomatic and asymptomatic athletes at rest. During exercise, symptomatic subjects have a longer OCTT and a higher intestinal permeability, which is more pronounced during running than during cycling.

Beta2-microglobulin concentrations in cerebrospinal fluid correlate with neuroimaging findings in newborns with symptomatic congenital cytomegalovirus infection.

OVERVIEW: In newborns with symptomatic congenital cytomegalovirus (CMV) infection, neuroimaging is the best available predictor of neurodevelopmental outcome. Cerebrospinal fluid (CSF) findings in congenital CMV infection have seldom been described. Neonates with central nervous system infections present high CSF Beta(2)-microglobulin (beta(2)-m) levels. OBJECTIVES: The objectives of this study were: (1) to determine whether CSF beta(2)-m is increased in newborns with symptomatic congenital CMV infection, and (2) to examine its correlation with neuroimaging findings. MATERIALS AND METHODS: Fourteen newborns with symptomatic congenital CMV infection admitted to La Paz Hospital from 1990 through 2004 underwent determination of CSF beta(2)-m. Ninety-three newborns, constituting the comparison group, underwent CSF beta(2)-m determination as part of a sepsis or meningo/encephalitis work-up, and at discharge had sterile cultures and normal neurological status. Neuroimaging findings were scored according to a semiquantitative system: (0) no abnormalities; (1) single punctate periventricular (PV) calcification and/or hyperechogenic areas in the thalamus and basal ganglia; (2) multiple discrete PV calcifications and/or ventriculomegaly; and (3) extensive PV calcifications and/or brain atrophy. DISCUSSION AND CONCLUSION: CSF beta(2)-m was increased in newborns with CMV infection (median 6.21 mg/L) compared with controls (1.68 mg/L) (P<.001). beta(2)-m showed a correlation with neuroimaging scores (r (s)=0.753, P=.002). beta(2)-m was higher in patients who scored 2-3 (12.83 mg/L) than in patients who scored 0-1 (5.52 mg/L) (P=.028). CSF beta(2)-m is increased in newborns with symptomatic congenital CMV infection and correlates with neuroimaging abnormalities. beta(2)-m appears to be an indicator of the severity of brain involvement in congenital CMV infection.

Reactive nitrogen intermediates in experimental trichomoniasis induced with isolates from symptomatic and asymptomatic women.

Trichomoniasis is the interplay between the infecting parasite, Trichomonas vaginalis, and the host, on which the clinical presentation of the disease depends. Although the clinical spectrum varies from an asymptomatic state to mild, moderate or severe symptoms, the exact virulence markers of T. vaginalis have not been well elucidated. Free radical generation during the disease process and its role in pathogenesis has been reported in various microbial diseases. In the present study, an attempt has been made to study reactive nitrogen intermediate (RNI) concentrations in experimental animals infected with T. vaginalis isolates from symptomatic and asymptomatic women. A significant increase in polymorphs, vaginal epithelial cells and RNI levels was observed in mice infected with isolates from symptomatic and asymptomatic subjects as compared to uninfected controls. The mean concentration of RNI in the vaginal tissue of mice infected with isolates from symptomatic women (75.5+/-7.7) was significantly higher than that of the vaginal tissue of mice infected with isolates from asymptomatic women (47.9+/-7.8), while it was less in the vaginal washes and plasma of mice infected with isolates from symptomatic women (18.7+/-3.6 and 17.1+/-3.3, respectively) compared to those infected with isolates from asymptomatic women (28.9+/-7.3 and 26.7+/-4.4, respectively), which may be due to different macrophage populations with different functional capabilities. Our study indicates that RNI production may play a role in establishing the infection.

Laparoscopic blockage of uterine artery and myomectomy: a new method of treating symptomatic uterine leiomyomas.

BACKGROUND: The goal of this study was to evaluate the effects of laparoscopic coagulation or blockage of the uterine arteries and myomectomy in treating symptomatic myomas. METHODS: A total of 142 women with symptomatic fibroids warranting surgical treatment and wanting to retain their uteri were treated by laparoscopic coagulation or blocking of the uterine arteries and myomectomy. RESULTS: Most of the 142 patients had multi-myomas of the uterus, as intramural myomas (54), subserous myomas (65), and submucosal myomas (25). The number of myomas in each patient varied from 1 to 4. The size of the myomas in all patients ranged from 2 to 12 cm. In 86 cases (60.4%) the uterine wall was sutured in one layer. Average operating time was 124.2 +/- 33.1 min, and average blood loss was 117.8 +/- 48.6 ml. Mean postoperative hospital stay was 4.8 +/- 1.2 days. All patients underwent technically successful laparoscopic coagulation or blocking of uterine arteries and myomectomy without intraoperative complications. The mean follow-up time was 16.2 months (16-26). Symptomatic improvement was achieved in all patients. Five patients experienced recurrence of myomas. CONCLUSIONS: Laparoscopic coagulation or block of the uterine arteries and myomectomy appears to be a safe, effective, and promising new method for treating symptomatic uterine myomas.

Long-term results after laparoscopic unroofing of solitary symptomatic congenital liver cysts.

BACKGROUND: Reports about laparoscopic management of symptomatic nonparasitic liver cysts are increasing, proving the procedure feasible and safe. However, late results of endoscopic unroofing currently are not available. The primary aim of the study was to offer long-term results with a follow-up of more than 5 years. Two diagnostic pitfalls are presented. METHODS: Preoperatively, diagnosis was established by sonography, computed tomography (CT) scan, echinococcus serology, and tumor-marker measurement. The outcome of 12 laparoscopic fenestrations in 11 patients with symptomatic solitary liver cysts is presented. Nine patients were reexamined after a median observation time of 3.1 years (range, 0.6-6.4 years) by clinical investigation and ultrasonography, CT scan, or magnetic resonance imaging (MRI), respectively. RESULTS: All operations could be finished laparoscopically, and no death occurred. Simultaneous cholecystectomy was performed in six cases. All patients experienced immediate relief of symptoms. Postoperatively, no complications were observed except one patient with unilateral brachial vein thrombosis. Histologically, we discovered one hydatide cyst and one cystadenoma underlying the cystic disorder leading to further therapy. At follow-up, one of the remaining seven patients (14.3%) suffered symptomatic recurrence and successfully underwent reoperation endoscopically. CONCLUSIONS: The results of this study confirm the outcome reported previously after short- and intermediate-term follow-up showing that laparoscopic management of symptomatic solitary nonparasitic liver cysts is permanently successful in a large majority of cases when diagnosis is correct.

The surgical treatment of intracranial aneurysms based on computer tomographic angiography alone--streamlining the acute mananagement of symptomatic aneurysms.

BACKGROUND: We aimed to prospectively assess the usefulness of computer tomographic angiography (CTA) in streamlining the management of symptomatic intracranial aneurysms in a tertiary neurosurgical unit, from admission to surgery. METHODS: We performed a prospective evaluation over a 2-year period of all symptomatic intracranial aneurysms managed according to a standardized departmental protocol, to assess how CTA has impacted the decision-making process pertaining to the suitability of this investigation to proceed directly to surgery. FINDINGS: A total of 90 patients with intracranial aneurysms were treated over the 2-year period. 23 (26%) underwent endovascular occlusion while 67 (74%) patients underwent a surgical clipping procedure. In the surgical group, 22 (33%) patients had their aneurysms clipped based on CTA alone, while 45 (67%) required additional conventional angiography prior to surgery. Thus around one quarter of all patients treated for symptomatic intracranial aneurysms in our unit had their aneurysm secured surgically based solely on CTA. INTERPRETATION: CTA significantly influences the acute management of symptomatic intracranial aneurysms by streamlining the decision-making process during the early and acute management of these lesions.

Comparison of vascular smooth muscle cell apoptosis and fibrous cap morphology in symptomatic and asymptomatic carotid artery disease.

The biological cascades that lead to carotid plaque disruptions and symptoms are largely unknown. Certain cellular events within the plaque might be responsible for destabilizing the plaque, though the popular belief is that the plaque size is directly related to symptoms. The aim of our study was to assess the morphology of the fibrous cap and apoptosis in the plaque and compare these two pathological features in symptomatic and asymptomatic carotid artery disease. Our work was carried out in plaques obtained following carotid endarterectomy performed for symptomatic disease (including hemispheric transient ischemic attacks, amaurosis fugax, or stroke) or asymptomatic high-grade severe stenosis. Scion images of Gomori's stained sections were used to measure fibrous cap thickness and area. TUNEL assay was performed to assess the extent of apoptosis. The results indicated that the area of the fibrous cap did not significantly correlate with the presence of symptoms. There was a higher percentage of apoptotic nuclei and the thinner fibrous cap in symptomatic plaques than in asymptomatic plaques. This finding suggests that these factors might be involved in destabilizing plaque, causing rupture and leading to symptomatic carotid disease.

Open pilot study of ultrasound-guided intra-articular injection of hylan G-F 20 (Synvisc) in the treatment of symptomatic hip osteoarthritis.

Patients suffering from hip osteoarthritis (OA) are frequently symptomatic, and the disease can result in significant limitation of patients' activity and high social costs. Hip OA is generally managed with systemic treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs) and/or symptomatic slow acting drugs. Viscosupplementation with hyaluronan (HA) or its derivatives, which aims to restore the physiological and rheological features of the synovial fluid to improve symptoms, is now a routinely prescribed treatment for OA of the knee. However, few data exist in the literature regarding the use of viscosupplementation in the treatment of hip OA. The objective of this prospective, open, uncontrolled pilot study was to investigate the safety and effectiveness of intra-articular injection, under ultrasound control, of hylan G-F 20 for the treatment of OA of the hip. Twelve patients (> or =40 years old) with symptomatic hip OA were treated with one injection of 2 ml of hylan G-F 20 under ultrasound guidance. During the study, patients were evaluated for safety and efficacy using the Lequesne index, a visual analogue scale (VAS) measure of hip OA pain and analysis of NSAID consumption. Patients treated with hylan G-F 20 in this study showed clinically significant reductions in Lequesne and VAS scores and in the consumption of NSAIDs up to 3 months after the injection. In the 12 patients treated (total of 14 injections), no systemic adverse events were observed. Three patients reported mild, local pain post-injection. This study demonstrates the potential of ultrasound-guided intra-articular injections of a viscosupplement into the hip joint and gives positive preliminary information about the safety and efficacy of hylan G-F 20 for the treatment of symptomatic hip OA.

The symptomatic effects of intra-articular administration of hylan G-F 20 on osteoarthritis of the hip: clinical data of 6 months follow-up.

Hip osteoarthritis (OA) is usually managed with systemic treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs) and/or symptomatic slow-acting drugs. Unfortunately, many patients either cannot tolerate NSAIDs or suffer serious, even fatal, NSAID-induced side effects, predominantly gastrointestinal ulceration and bleeding. Viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid, is a well-accepted therapeutic option in knee OA patients, but limited data exist in the literature about its potential benefit for the treatment of hip OA. The purpose of this study is to observe the effects of hylan G-F 20 administered through ultrasound (US)-guided intra-articular (IA) injections in patients with symptomatic hip OA. We treated 30 patients with symptomatic hip OA. Under US guidance, 7 patients received one injection, 21 patients had two injections, and 2 patients received three injections, each with 2 ml of hylan G-F 20. Lequesne index, VAS scale of hip pain, and NSAID consumption were evaluated at baseline as well as 2 and 6 months after the beginning of the treatment. No systemic adverse events were observed. Lequesne index, VAS pain score, and NSAID consumption showed a reduction that was statistically significant to the baseline. The present observation suggests the potentiality for the safety and efficacy of hylan G-F 20 injected under US guidance in patients with symptomatic hip OA. Further controlled studies are needed.

Effect of cardiac resynchronization therapy on sleep quality, quality of life, and symptomatic depression in patients with chronic heart failure and Cheyne-Stokes respiration.

Patients with heart failure (HF) often suffer from sleep-related breathing disorders (SRBD) like Cheyne-Stokes respiration (CSR). Cardiac resynchronization therapy (CRT) improves myocardial function and exercise capacity in patients with HF and conduction disturbances. As CRT has been shown to reduce CSR in patients with HF, it is not clear whether CRT improves quality of life and symptomatic depression by improvement of apnea/hypopnea index (AHI) and sleep quality. Forty-two HF patients with conduction disturbance before CRT were screened for CSR and evaluated for sleep quality [Pittsburgh Sleep Quality Index (PSQI)], quality of life score [36-item short form (SF-36)], depression, and exercise capacity (VO2 peak) and ejection fraction (EF). Eighteen patients (three females, age 61+/-10, body mass index 24+/-4 kg m(-2), EF 24+/-4%, QRS complex duration 156+/-32 ms) presented CSR with an AHI of 18+/-8 (11 CSR, 7 mixed). Fourteen patients showed no SRBD (PSQI<5,AHI<5). All patients received CRT and were reevaluated after 18+/-7 weeks. CSR worsen quality of life in seven of eight terms compared to patients without SRBD. Symptomatic depressive symptoms (Beck Depression Inventory>10) were only present in patients with CSR. CRT results in improvement of peak VO2 and EF. There was no difference between patients with CSR and without SRBD on exercise capacity or EF under CRT, whereas CRT led to a significant decrease in AHI (18+/-8 to 3+/-2, p<0.0001), PSQI (18+/-4 to 6+/-3, p=0.0007), with reduction of depression score (12+/-3 to 4.8+/-3, p=0.004). In patients with HF, CSR is associated with symptomatic depressive syndromes and impaired quality of life. CRT reduced CSR with improvement of sleep quality and symptomatic depression.

Symptomatic cryoglobulinemia.

1. Treatment of symptomatic cryoglobulinemia is exceedingly challenging due to the multisystemic nature of its presentation, the variability of its course, and the paucity of effective therapeutic options supported by randomized controlled clinical trials. 2. Patients with mild, relatively asymptomatic disease should be observed without introduction of systemic therapy. 3. Patients with symptomatic type I secondary cryoglobulinemia should be treated as appropriate for their underlying lymphoproliferative or plasmaproliferative disorder. 4. Patients with secondary type II or type III cryoglobulinemia should be treated for their underlying connective tissue, lymphoproliferative, or liver disorder or infection. 5. First line treatment for symptomatic, essential type II or type III cryoglobulinemia associated with hepatitis C should include interferon (IFN)-alpha. Depending on the severity of clinical presentation, adjuvant corticosteroids or plasmapheresis should be considered. 6. Life-threatening or acute organ-threatening presentations should be managed with combined modality therapy, which should include high-dose corticosteroid, plasmapheresis, or alkylator-based therapy. 7. Many chemotherapeutic and immunosuppressive strategies have been tried but not systematically tested; their value is therefore unknown. 8. Challenges for the future of treating symptomatic cryoglobulinemia include devising better therapies and more systematic evaluation of existing therapies.

Symptomatic and silent myocardial ischemia during exercise testing in coronary artery disease.

During exercise by patients with coronary artery disease (CAD), electrocardiographic evidence of myocardial ischemia may precede the onset of angina or may be unassociated with angina, even at peak levels of stress. However, neither the precise incidence of silent versus symptomatic ischemic episodes nor their interrelation in this setting has been clearly defined. The prevalence of silent and symptomatic myocardial ischemia during treadmill exercise testing was determined in 92 patients with angiographically documented CAD. The study group comprised 77 men (84%) and 15 women (16%) of mean age 57 years (range 32 to 79). Exercise testing resulted in ischemic ST-segment depression (greater than or equal to 1 mm for greater than or equal to 80 ms) only or in association with delayed (greater than or equal to 1 minute) angina in 39 patients (42%); angina only or in association with delayed ST-segment depression occurred in 42 patients (46%); and simultaneous occurrence of angina and ST-segment depression was noted in 11 patients (12%). Analysis of clinical, exercise and angiographic factors (age, sex, history of myocardial infarction, heart rate, maximal ST-segment depression, extent of CAD and left ventricular ejection fraction) revealed no significant correlation with the frequency of symptomatic and silent myocardial ischemia during exercise. Asymptomatic myocardial ischemia occurred commonly during exercise in patients with CAD, but there were no differences in the characteristics of patients with symptomatic and asymptomatic episodes.

Clinical significance and predisposing factors to symptomatic bradycardia and hypotension after percutaneous transluminal coronary angioplasty.

Of 180 consecutive patients who underwent uneventful percutaneous transluminal coronary angioplasty (PTCA), 25 (13.9%) had at least 1 episode of symptomatic bradycardia and hypotension during the early postprocedure period. Symptomatic bradycardia and hypotension occurred 1 to 10 hours (mean 4 +/- 2) after PTCA. A higher incidence of symptomatic bradycardia and hypotension was found in patients receiving regular treatment with beta blockers (26% vs 10% in patients without beta blockers in their regimen, p < 0.01), diltiazem or verapamil (20% vs 9%, p < 0.025), or both a beta blocker and diltiazem or verapamil (64% vs 11%, p < 0.001). A higher incidence was also associated with angioplasty of the left anterior descending coronary artery compared with angioplasty of the other coronary arteries (22% vs 8%, p < 0.01). It is concluded that symptomatic bradycardia and hypotension is a common occurrence after PTCA. The incidence is higher after PTCA to the left anterior descending coronary artery and in patients receiving diltiazem, verapamil, and beta-blocking agents; it is particularly high in patients receiving a combination of a beta-blocking agent and either diltiazem or verapamil.

The effect of tocolytic use in the management of symptomatic placenta previa.

OBJECTIVE: The null hypothesis is that tocolysis has no effect on pregnancy prolongation in the aggressive expectant management of symptomatic preterm placenta previa. STUDY DESIGN: One hundred twelve preterm pregnancies with confirmed placenta previa and an initial episode of acute vaginal bleeding were selected for this retrospective analysis. Exclusion criteria included gestational age > or = 35 weeks, delivery within 24 hours of admission, prior treatment for bleeding or preterm labor, and contraindications to tocolytic use. Tocolysis was prescribed, at the discretion of the treating clinical staff, in selected pregnancies with significant uterine contractions after admission of the patient. The majority of treated patients (85%) received intravenous magnesium sulfate and/or oral or subcutaneous beta-sympathomimetics within 24 hours of admission. Most patients remained hospitalized until delivery under this aggressive expectant management protocol. Both treated and untreated control study groups were similar at inclusion with regard to parity, gestational age, contraction frequency, and degree of initial bleeding. Outcome variables for each treatment group were obtained from final chart review. Continuous and categoric variables were compared with Student t test or chi 2 analysis-Fisher's exact test, respectively. RESULTS: The clinical use of tocolysis in symptomatic placenta previa was associated with a clinically significant delay of preterm delivery. Significant improvement in clinical parameters such as interval from admission to delivery (39.2 vs 26.9 days, p < 0.02) and birth weight (2520 vs 2124 gm, p < 0.03) was observed in the tocolysis group. There was no observed statistical difference between the two treatment groups with regard to incidence of recurrent bleeding, interval from admission to first recurrent bleeding, and need for transfusion. There was a trend for patients with multiple bleeding episodes to have been receiving tocolytic therapy (p < 0.10). A trend for requiring a postpartum transfusion was also noted in the tocolysis group (p < 0.09). Treated pregnancies receiving long-term maintenance tocolysis with oral or subcutaneous terbutaline exhibited a greater degree of pregnancy prolongation than those treated with short-term intravenous magnesium alone (43.7 vs 15.3 days, p < 0.02). CONCLUSIONS: This retrospective analysis suggests that tocolytic intervention in cases of symptomatic preterm previa may be associated with clinically significant prolongation of pregnancy and increased birth weight. Tocolytic therapy in these cases does not appear to have an impact on frequency or severity of recurrent vaginal bleeding. Further prospective analysis may delineate the role of tocolysis in the aggressive expectant management of symptomatic placenta previa.

Cognitive bias in symptomatic and recovered agoraphobics.

Symptomatic agoraphobics, recovered agoraphobics, and normal control subjects completed a series of sentence stems that had either ambiguous or unambiguous meanings, and had either a potentially threatening or a nonthreatening connotation. The written completions made by subjects to these stems were classified as indicating either a biased (i.e. threat-related) or unbiased interpretation of the meaning of the stem, and if a biased interpretation was made, whether the subject indicated efforts at adaptive coping with the perceived threat. Results indicated that symptomatic agoraphobics exhibited strong biases for interpreting information as threatening, relative to normal control subjects. Moreover, recovered agoraphobics resembled symptomatic agoraphobics more than normal control subjects, thus indicating that cognitive biases may persist following cessation of panic attacks and reductions in avoidance behavior. However, recovered agoraphobics also exhibited tendencies to cope adaptively with perceived threats whereas symptomatic agoraphobics did not.
