This study examined the sociodemographic correlates of psychiatric illness in a primary care centre in Kuwait. A total of 164 psychiatric patients seen over a 3-year period formed the experimental group while 165 nonpsychiatric patients attending the same centre formed the control group. Results showed significant differences in basic demographic variables of the 2 groups. The psychiatric patients were significantly more likely to be single, unskilled, young, less educated and living alone or in an overcrowded household and to report more recent life events than controls. The absence of family and social support, lacking a meaningful job and chronicity of illness were significantly correlated with poor treatment response. Possible interpretations of the results were discussed in the cultural context of our patients. The fact that 57% of the psychiatric patients had been ill for more than 6 months prior to consultation highlights the importance of orientation of primary care practitioners to the psychiatric aetiology of somatic presentation of many of their patients. 相似文献

We investigated whether chronic fatigue syndrome (CFS) patients have
physical and/or cardiovascular de-conditioning, in 273 CFS patients and 72
healthy controls. We used laboratory tests to assess haematological,
biochemical, endocrinological and immunological systems. The cardiovascular
system was assessed by echocardiography and carotid echography. Body
composition was determined by dual energy X-ray absorptiometry (DEXA). CFS
patients had smaller left ventricular end systolic (p < 0.001) and
diastolic (p = 0.008) dimensions but thinner posterior walls (p = 0.02)
than corresponding values in healthy controls. Left ventricular mass was
also reduced in CFS patients (p = 0.006). Both maximum (p < 0.001) and
minimum (p < 0.008) diameter of the carotid artery were smaller in CFS
patients. The laboratory screening tests showed significant differences in
serum albumin (p = 0.05), phosphate (p = 0.02), HDL-cholesterol (p = 0.03),
HDL:total cholesterol ratio (p = 0.01), triglycerides (p = 0.02),
neutrophils (p = 0.01) and thyroid-stimulating hormone (p = 0.04) between
CFS patients and controls. Male CFS patients had an increased percentage of
fat mass compared with healthy male subjects (p = 0.02). This large group
of CFS patients had evidence of physical and cardiovascular
de-conditioning, suggesting that in these patients a graded exercise
programme could lead to physical reconditioning and could increase their
ability to perform physical activities.

Calcified amorphous tumors (CAT) of the heart are rare primary cardiac tumors characterized by heavy myocardial and valve
apparatus calcification. The relationship of the entity with ventricular arrhythmia, if any, is unknown. We describe a case
of cardiac CAT in a 58-year-old woman with prior cardiac arrest and recurrent ventricular tachycardia who presented for radiofrequency
ablation. Pre-ablation intracardiac echocardiogram revealed the characteristic endomyocardial calcific pattern associated
with this tumor that precluded catheter manipulation in the left ventricle. The imaging characteristics and management are
described. 相似文献

BACKGROUND AND AIM OF THE STUDy: Long-term echocardiographic follow up studies of mitral balloon valvuloplasty (MBV) are scarce. The study aim was to assess the long-term results (up to 17 years) of MBV and to identify predictors of restenosis and event-free survival. METHODS: The immediate and long-term clinical and echocardiographic results for 520 consecutive patients (mean age 31 +/- 11 years) who underwent successful MBV for severe mitral stenosis (MS) and were followed up for a mean of 7.3 +/- 4.35 years (range: 1 to 17 years) after MBV, were reported. RESULTS: Immediately after MBV, the mitral valve area (MVA) was increased from 0.92 +/- 0.17 to 1.96 +/- 0.29 cm2 (p < 0.0001). Restenosis occurred in 133 patients (25.6%), and was less frequent (16.7%) in patients with a low mitral echo score (MES < or = 8). Actuarial freedom from restenosis at 10, 15, and 17 years was 73 +/- 2%, 43 +/- 4%, and 23 +/- 6%, respectively, and was significantly higher in patients with MES < or = 8 (84 +/- 2%, 52 +/- 6%, and 36 +/- 9%, respectively; p < 0.001). Event-free survival (death, redo MBV, mitral valve replacement, NYHA class III or IV) at 10, 15, and 17 years was 82 +/- 2%, 45 +/- 5%, and 31 +/- 6% respectively, and was significantly higher for patients with MES < or = 8 (90 +/- 2%, 60 +/- 5%, and 51 +/- 8%, respectively; p < 0.001). Cox regression analysis identified MES > 8 (p < 0.0001) and post-procedure MVA (p = 0.044) as predictors of restenosis, and MES < or = 8 (p < 0.0001), age (p < 0.0001), and post-procedure MVA (p = 0.016) as predictors of event-free survival. CONCLUSION: MBV provides excellent long-term results for selected patients with MS. The long-term outcome of this procedure can be predicted from the baseline clinical and echocardiographic characteristics of the mitral valve. 相似文献

OBJECTIVE: Increasing evidence suggests long-term alendronate use may overly suppress bone metabolism, limiting repair of microdamage and creating risk for insufficiency fractures. The purpose of this study is to demonstrate an association between alendronate use and a specific pattern of low-energy femoral shaft fracture. DESIGN, SETTING, AND PATIENTS: A retrospective review was performed of patients with femoral shaft fractures admitted to a Level 1 trauma center between January 2002 and March 2007. Seventy low-energy fractures were identified. MAIN OUTCOME MEASURE: The medical records were reviewed, and the incidence and duration of alendronate use were recorded. The incidence of a specific femoral shaft fracture in those patients taking alendronate compared with those not being treated was determined. RESULTS: There were 59 females and 11 males. The average age was 74.7 years. Twenty-five (36%) were being treated with alendronate. None of the patients had used or were using other bisphosphonates. Nineteen (76%) of these 25 patients demonstrated a simple, transverse fracture with a unicortical beak in an area of cortical hypertrophy. This fracture pattern was seen in only 1 patient (2%) not being treated with alendronate. Alendronate use was a significant risk factor for the fracture pattern (odds ratio [OR]) 139.33, 95% CI [19.0-939.4], P < 0.0001). This pattern was 98% specific to alendronate users. The average duration of alendronate use in those with the pattern was significantly longer than those who did not exhibit the pattern but were taking alendronate, 6.9 years versus 2.5 years of use, respectively (P = 0.002). Only 1 patient with the fracture pattern had been taking alendronate for less than 4 years. CONCLUSIONS: Low-energy fractures of the femoral shaft with a simple, transverse pattern and hypertrophy of the diaphyseal cortex are associated with alendronate use. This may result from propagation of a stress fracture whose repair is retarded by diminished osteoclast activity and impaired microdamage repair resulting from its prolonged use. 相似文献

Elevated low-density lipoprotein (LDL)-cholesterol is associated with a significantly increased risk of coronary heart disease.
Ezetimibe is the first member of a new class of selective cholesterol absorption inhibitors. It impairs the intestinal reabsorption
of both dietary and hepatically excreted biliary cholesterol. Ezetimibe is an effective and safe agent for lowering LDL-C
and non HDL-C. Short term clinical trials have established the role of ezetimibe monotherapy and its use in combination with
statins. Furthermore, ezetimibe and statin combination therapy increased the percentage of patients who achieved their LDL-C
treatment goal. 相似文献

A survey of 523 facilities performing radiographic lumbosacral spine examinations was conducted as a part of the Nationwide Evaluation of X-Ray Trends program in 1987 and 1989. Average patient radiation exposure was measured by using a standard phantom developed by the Center for Devices and Radiological Health of the Food and Drug Administration, U.S. Public Health Service. Data pertaining to radiographic equipment, film processing, and radiographic techniques were obtained. The overall average entrance skin air kerma was 3.65 mGy (420 mR). Ninety-eight percent (496 of 506) of observed facilities used a grid, 89% (466 of 523) had tube potentials between 70 and 89 kVp, and 67% (280 of 418) used screen-film systems with a speed of 400. The most important finding is that underprocessing of film remains a major concern. Thirty-three percent (78 of 234) of the hospitals, 25% of the radiologists in private practice (four of 16), 33% of the nonradiologist private practitioners (27 of 82), and 48% (69 of 143) of the chiropractors underprocessed their film. 相似文献
