BACKGROUND: It is thought that women with polycystic ovary syndrome (PCOS) are at increased risk of developing cardiovascular diseases. METHODS: In this study, we used transthoracic echocardiography to measure coronary flow reserve (CFR) in 28 women with PCOS and in 26 healthy women. RESULTS: The PCOS and the control groups were similar in terms of age (27.1 +/- 4.5 versus 28.8 +/- 4.4 years) and BMI (26.6 +/- 5.7 versus 24.7 +/- 4.4 kg/m2). Fasting insulin levels and homeostasis model assessment insulin resistance index were higher in the PCOS group. LH, the LH/FSH ratio, total testosterone, free testosterone and androstenedione were higher in the PCOS group. FSH, estradiol, prolactin, progesterone, cholesterol, triglyceride and high-sensitive C-reactive protein were similar between the two groups, but homocysteine levels were higher in the PCOS group. Baseline diastolic peak f low velocity (DPFV) (25.0 +/- 4.6 versus 23.3 +/- 2.7 cm/s, P > 0.05), hyperaemic DPFV (71.2 +/- 12.8 versus 73.0 +/- 12.9 cm/s, P > 0.05) and CFR (2.8 +/- 0.8 versus 3.2 +/- 0.8 cm/s, P > 0.05) of the left anterior descending coronary artery were similar between the two groups. CONCLUSION: We conclude that in young women with PCOS and without cardiovascular risk factors, CFR is preserved. 相似文献

OBJECTIVES: Few data exist about the incidence of drug-induced acute pancreatitis in the general population. Although angiotensin-converting enzymes are generally well tolerated, acute pancreatitis has been reported in a few subjects treated with captopril, enalapril, and lisinopril. However, to our knowledge, there is no published data regarding recurrent pancreatitis secondary to lisinopril. Herein, we report the case of a 54-year-old man who developed recurrent acute pancreatitis after starting lisinopril. CLINICAL PRESENTATION: A 54-year-old man with a longstanding history of hypertension, treated with lisinopril 10 mg once daily, presented with acute pancreatitis. Other causes of the disease were ruled out. After cessation of lisinopril, his condition improved and his amylase level decreased. This was his third episode of acute pancreatitis since lisinopril had been started in 2002. After discontinuing lisinopril and beginning treatment with amlodipine 10 mg/d, the patient was well at follow-up examination and has not had another episode of pancreatitis during the subsequent 7 months. CONCLUSION: This case report demonstrates additional evidence of acute pancreatitis associated with an ACE inhibitor. 相似文献

Suffering comes in many ways for patients confronting cancer. One of these is an unspecifiable fear about death, which is an existential issue. The aim of this study was to investigate the relationship between death anxiety and its correlates in cancer patients. Seventy cancer patients were assessed using SCID-I, Templer's Death Anxiety Scale, the Hospital Anxiety (A) and Depression (D) Scale, the Distress Thermometer, the Visual Analogue Scale for pain (VAS), the Global Assessment of Functioning, and Glock and Stark's Dimensions of Religious Commitment scales, and these assessments were compared between cancer patients with and without death anxiety. Multiple regression analysis was conducted after correlation analysis between death anxiety and sociodemographic and clinical variables. Axis I psychiatric diagnosis, pain scores, and negative believes about what will happen after death were found to be higher in patients having death anxiety than patients not having death anxiety. Also life expectancy was perceived as shortened in patients with death anxiety. Death anxiety was associated with anxiety, depressive symptoms, and beliefs about what will happen after death. In conclusion, death anxiety could not be regarded as a natural consequence of having cancer; it is associated with the unresolved psychological and physical distress. 相似文献

It is not scarce that patients experience various extrapyramidal symptoms (EPS) during antidepressant drug therapy. Thus, choice of an antidepressant drug in case of extrapyramidal side effects, at present, is a dilemma. Escitalopram, which is a recently marketed selective serotonin reuptake inhibitors (SSRI), has no such reputation. There is just one case reported for tianeptine that induced abnormal involuntary movements/extrapyramidal side effects. We would like to present a case that was successfully managed with bupropion which had developed EPS during 2 different SSRI (sertraline and escitalopram) and tianeptine therapy. 相似文献

Purpose The aim of this study was to evaluate the efficacy of two absorbable film barriers, polylactic acid and sodium hyaluronate–carboxymethyl
cellulose, in preventing postoperative intra-abdominal adhesions, inflammation, and fibrosis in an animal model.
Methods Forty Wistar albino rats were grouped as polylactic acid, sodium hyaluronate–carboxymethyl cellulose, and control. All rats
underwent laparotomy with subsequent cecal wall abrasion and abdominal wall injury. The two treatment groups received polylactic
acid or sodium hyaluronate–carboxymethyl cellulose film barriers, while control group received nothing. On postoperative day 21,
three observers graded the intra-abdominal adhesions and resected specimens. Fibrosis, inflammation, and adhesions were graded
using quantitative scoring systems.
Results When compared to control group, polylactic acid group showed significantly less inflammation and adhesion (p < 0.005), while there was no significant difference for fibrosis. Sodium hyaluronate–carboxymethyl cellulose group has showed
significantly less adhesions (p < 0.005), but there were no significant differences among fibrosis and inflammation when compared to control group. There
were no significant differences between polylactic acid and sodium hyaluronate–carboxymethyl cellulose groups on adhesion
formation, inflammation, or fibrosis.
Conclusions Placement of polylactic acid or sodium hyaluronate–carboxymethyl cellulose film barriers between injured surfaces is associated
with a significantly reduced rate of postoperative adhesions. No superiority was detected between two barriers. 相似文献

BACKGROUND: The drug 3,4-methylenedioxymethamphetamine (MDMA), otherwise known as “ecstasy,” is a synthetic amphetamine that produces euphoria, increases sociability and energy, and is often used as a “weekend” recreational drug by young adults.CASE SUMMARY: A 23-year-old male (height, 184 cm; weight, 68 kg) presented to the emergency department of Marmara University Hospital, Istanbul, Turkey, with jaundice and nausea lasting for 6 days. The patient reported that he had been a chronic user of MDMA for 2 years. He also reported that 1 week before presenting, he had ingested twice (2 tablets) the usual amount (1 tablet) of the drug at the same time. Blood tests were performed and hematologic findings were as follows: aspartate aminotransferase (AST), 1423 U/L (reference range, 10-37 U/L); alanine aminotransferase (ALT), 2748 U/L (10-40 U/L); alkaline phosphatase, 271 U/L (0-270 U/L); γ-glutamyl transpeptidase, 124 U/L (7-49 U/L); total bilirubin, 13.23 mg/dL (0.2-1 mg/dL); direct bilirubin, 8.75 mg/dL (0-0.3 mg/dL); amylase, 80 U/L (0-220 U/L); prothrombin time, 21.2 sec; activated partial thromboplastin time, 37.3 sec; and international normalized ratio, 1.66. Liver enzymes and bilirubin levels were found to be extremely high (AST = 40x normal, ALT = 70x normal, and bilirubin = 13x normal). Viral, autoimmune, and metabolic causes were excluded. Serologic tests for hepatitis A, B, and C viruses, mononucleosis, cytomegalovirus, and HIV infection were all negative. A diagnosis of ecstasy-induced toxic hepatitis was made. The patient's medical history further revealed that the current incident was actually his second occurrence of jaundice and acute hepatitis associated with the ingestion of higher amounts (twice the usual amount of MDMA he ingested at the same time). Supportive therapy (IV saline and vital sign monitoring) was initiated and liver enzymes, bilirubin levels, and prothrombin times were monitored daily. All had returned to normal values in 2 weeks.CONCLUSIONS: MDMA, or the recreational drug ecstasy, might be responsible for acute hepatitis and/or acute liver failure, particularly in young people. Physicians might need to be alert to the possibility of ecstasy-induced liver damage occurring in younger patients, although the presence of other hepatotoxins and alternative diagnoses requires exclusion. The use of this drug should be investigated in young patients with severe hepatitis of unknown origin. 相似文献

Aims and objectives Health‐related quality of life (HRQL) is an important patient‐reported outcome when identifying the effects of the angina and evaluating the efficacy of treatment. The aim of this study was to determine the reliability and validity of the Turkish version of the MacNew Heart Disease HRQL Questionnaire (MacNew) in patients with angina. Method The Short Form SF‐36, the MacNew, and the Hospital Anxiety and Depression Scale were completed by the 125 patients in first 2–3 days after admission to the coronary care unit. Internal consistency reliability (Cronbach’s α) and reproducibility (intraclass correlation coefficients, ICC) of the MacNew were assessed, and test–retest reproducibility was evaluated over a 2‐month period in 25 clinically stable patients. Results The original three‐factor structure for the Turkish MacNew was confirmed, with construct validity only partially confirmed; reliability statistics show that Cronbach’s α exceeded 0.80 and the ICC exceeded 0.60 for all MacNew scales. Discriminative validity of the MacNew was confirmed. Conclusion The MacNew appears to be reliable and valid in Turkish patients with angina. 相似文献

The time-related alteration of plasma B-type natriuretic peptide levels after percutaneous coronary interventions has been investigated chiefly in patients with acute coronary syndromes; very few data are available in patients with stable coronary artery disease. Therefore, we aimed to evaluate the alterations of plasma B-type natriuretic peptide levels, and the effects of lesion complexity on these levels, after elective percutaneous coronary interventions in stable coronary artery disease patients. We enrolled 103 of these patients and used modified American College of Cardiology/American Heart Association lesion morphology criteria to qualitatively evaluate the angiograms: type A and B1 lesions were categorized as simple, and type B2 and C lesions were designated as complex. Plasma B-type natriuretic peptide levels were determined before intervention and 1 and 24 hours afterwards. Median baseline B-type natriuretic peptide levels were significantly higher in patients who had complex lesions (n=53) (108 pg/mL) compared with those who had simple lesions (n=50) (33 pg/mL) (P <0.001), and this difference was maintained 1 and 24 hours after intervention (P = 0.003 and P = 0.001, respectively). However, for both lesion types, percutaneous coronary intervention procedures did not significantly alter plasma B-type natriuretic peptide levels (all P >0.05). On binary logistic regression analysis, age and lesion complexity were found to be independently associated with B-type natriuretic peptide levels. We conclude that, in stable coronary artery disease patients, elective percutaneous coronary intervention does not cause any significant alteration in plasma B-type natriuretic peptide levels. However, elevated levels are significantly associated with more complex lesions and with advanced age. 相似文献
