Objectives Although development of new treatment modalities limited digoxin usage, digoxin intoxication is still an important issue which could be easily overlooked. In this report we analyzed a case series definitively diagnosed as digoxin intoxication in the modern era. Methods We analyzed 71 patients hospitalized with digoxin intoxication confirmed by history, complaints, clinical and electrocardiograph (ECG) findings, and serum digoxin levels > 2.0 ng/mL, during a five year period. The demographic and clinical data, indications for digoxin use, digoxin dosage, concurrent medications, laboratory data, hospital monitoring, and ECG findings were obtained from all patients. Results Thirty-eight of 71 patients (53.5%) had symptoms of heart failure during admission or later. Sixty-four percent of patients were older than 75 years. The percentage of females was 67%. Atrial fibrillation, hypertension and gastrointestinal complaints were more frequent in the females (64% in females, 30% in males, P = 0.007; 81% in female, 52% in males, P = 0.01; 50% in female, 17.3% in males, P = 0.008, respectively). The mortality rate during the hospital course was 7%. Conclusion This report demonstrated the reduced mortality rates in patients with digoxin intoxication over the study period. Gastrointestinal complaints are the most common symptoms in this population. 相似文献

Chronic diffuse pain and hyperalgesia are two cardinal features of pain in fibromyalgia syndrome (FMS). Advancement in understanding
the pathophysiology and treatment efficacy often depends on pain that is defined and measured. Pain is a subjective phenomenon
that we can measure only by indirect methods. In this article, we provide methodological guidelines for pain assessment and
review recent developments in understanding pain mechanisms and evaluating treatments in FMS. Finally, we demonstrate the
heterogeneity of the FMS population and suggest the need for matching treatments to patient characteristics in order to improve
clinical outcomes. 相似文献

Identifying methods to improve assay sensitivity in randomized clinical trials (RCTs) may facilitate the discovery of efficacious pain treatments. RCTs evaluating pain treatments typically use average pain intensity (API) or worst pain intensity (WPI) as the primary efficacy outcome. However, little evidence is available comparing the assay sensitivity of these 2 measures. In this systematic review and meta-analysis, we comprehensively reviewed all low back pain, osteoarthritis pain, fibromyalgia, diabetic peripheral neuropathy pain, and postherpetic neuralgia RCTs that used a parallel group design. Eligibility required: 1) primary RCT report published between 1980 and 2016, 2) comparing 1 or more active, efficacious pharmacologic pain treatment(s) with placebo, and 3) providing data on the standardized effect size (SES) for API as well as WPI for all treatment arms. Twenty-seven active versus placebo comparisons were identified in 23 eligible articles. Using a random-effects meta-analysis, API SES and WPI SES did not differ significantly (difference?=??.021, 95% confidence interval = ?.047 to .004, P?=?.12). The findings indicate that, depending on the objectives of the study, either API or WPI could be used as a primary outcome measure in clinical trials for the chronic pain conditions included in this analysis.
Perspective
Understanding the comparative assay sensitivity of API and WPI may advance pain treatment research. A meta-analysis of trials of efficacious pharmacologic treatments in 5 pain conditions did not show a statistically significant difference between the assay sensitivity of API and WPI. 相似文献37.

We report the unusual occurrence of complete heart block during attempted right coronary artery cannulation in a patient with pre-existing uncomplicated right bundle branch block (RBBB). This complication occurred due to accidental impingement of the Judkin's right coronary catheter on the left bundle when it transiently slipped across the aortic valve. The block resolved without any complication. 相似文献

[Purpose] Diabetes mellitus is a metabolic disorder resulting from a defect in insulin
secretion, insulin action, or both. A consequence of this is chronic hyperglycemia with
disturbances in carbohydrate, fat and protein metabolism. We investigated whether there is
any difference among DM patients and a control group in terms of lumbar and femur BMD
(bone mineral density), and standard deviation scores (Z score and T score). [Subjects and
Methods] This randomized, prospective, controlled, single-blind study was conducted in the
Physical Medicine and Rehabilitation Department Faculty of Medicine, Bezm-i Alem Vakıf
University. Patients with type 2 diabetes mellitus were included in the patient groups.
Healthy individuals were included in the control group. [Results] A total of 126 patients
completed the study (63 in the study group, 63 in the control group). There was no
significant difference in the results of the laboratory examinations of the cases. The
bone mineral densities of the cases were found to be significantly low in terms of the
lumbar (L1–4) T scores in the type 2 diabetes group. [Conclusion] Although osteoporosis is
one of the potential complications of type 1 diabetes, its effect on bone mineral density
in type 2 DM is controversial. In different studies, the bone mineral density values have
increased, decreased or remained normal. With the exception of the lumbar (L1–4) T score,
similar results were obtained in this study.Key words: Type 2 diabetes mellitus, Osteoporosis, Bone mineral density 相似文献
