The prevalence of fibromyalgia and its relation with headache characteristics in episodic migraine

The objective of this study was to assess the prevalence of fibromyalgia (FM) in patients with episodic migraine and to evaluate the relationship between migraine characteristics and FM. One hundred and eighteen consecutive patients (mean age?=?38 years, 75 % women) fulfilling the International Classification of Headache Disorders-II criteria for migraine with (n?=?22) and without (n?=?96) aura from an outpatient headache clinic of a university hospital were evaluated. The diagnosis of FM was made based on the 1990 American College of Rheumatology classification criteria. Participants completed some self-administered questionnaires ascertaining sociodemographics, headache severity, frequency and duration, headache-related disability (Headache Impact Test [HIT-6]) and Migraine Disability Assessment Scale, widespread musculoskeletal pain (visual analog scale), depression (Beck depression inventory), anxiety (Beck anxiety inventory), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Assessment of Fatigue), and quality of life (Short Form-36 Health Survey [SF-36]). In patients with FM, the tender point count and the Fibromyalgia Impact Questionnaire were employed. FM was diagnosed in 37 (31.4 %) of the patients. FM comorbidity was equally distributed across patients with and without aura. Severity of migraine headache, HIT-6, and anxiety were especially associated with FM comorbidity. Patients suffering from migraine plus FM reported lower scores on all items of the SF-36. This study indicates that the assessment and management of coexisting FM should be taken into account in the assessment and management of migraine, particularly when headache is severe or patients suffer from widespread musculoskeletal pain.     

Efficacy of the Combination of Tetracycline, Amoxicillin, and Lansoprazole in the Eradication of Helicobacter pylori in Treatment-Naïve Patients and in Patients Who Are Not Responsive to Clarithromycin-Based Regimens: A Pilot Study

Background/Aims

The aim of this study was to evaluate the eradication rate of a triple therapy regimen that included a proton pump inhibitor, amoxicillin, and tetracycline instead of clarithromycin in treatment-Naïve patients and in patients who did not respond to standard triple therapy.

Methods

This study included 110 patients infected with Helicobacter pylori. Patients in groups A and B were treatment-Naïve, and those in group C were not responsive to previous standard triple therapy. Patients in group A (n=40) received lansoprazole 30 mg b.i.d., amoxicillin 1,000 mg b.i.d., and clarithromycin 500 mg b.i.d. for 14 days. Patients in groups B (n=40) and C (n=30) received lansoprazole 30 mg b.i.d., amoxicillin 1,000 mg b.i.d., and tetracycline 500 mg q.i.d. for 14 days.

Results

In group A, eradication was achieved in 18 (45%) of the 40 patients included in the intention-to-treat (ITT) analysis and in 18 (47.4%) of the 38 patients included in the per-protocol (PP) analysis. In group B, eradication was achieved in 15 (37.5%) of the 40 patients included in the ITT analysis and in 15 (39.3%) of the 38 patients included in the PP analysis. In group C, eradication was achieved in 14 (46.6%) of the 30 patients included in the ITT analysis and in 14 (43.8%) of the 29 patients included in the PP analysis. There was no statistically significant difference among the 3 groups with regard to eradication rates (p>0.05).

Conclusions

Despite the low rate of resistance to tetracycline, the combination of lansoprazole, amoxicillin, and tetracycline instead of clarithromycin is not a good option for the eradication of H. pylori.     

High plasma levels of factor VIII: an important risk factor for isolated pulmonary embolism

OBJECTIVE: The aim of the study was to investigate whether factor V Leiden and prothrombin G20210A mutations, elevated levels of factor VIII and factor IX are associated with pulmonary embolism (PE). METHODS: Sixty-four patients with objectively documented PE and 64 control subjects were included in this study. The authors divided the 64 subjects with PE into those with PE and deep vein thrombosis (combined form of venous thromboembolism, n = 26) and those with PE without deep vein thrombosis (isolated PE n = 38). RESULTS: There was no significant difference between the PE groups and the control subjects with regard to the presence of factor V Leiden and prothrombin mutations and elevated levels of factor IX. Using the 90th percentile measured in control subjects (P(90) = 168 U/dL) as a cut-off point for factor VIII levels, the authors found an 11-fold increased risk for both isolated PE patients and patients with a combined form of venous thromboembolism who have factor VIII levels >168 U/dL compared with individuals having factor VIII levels below this cut-off point. The risk was not affected by adjustments for other possible risk factors. CONCLUSIONS: Elevated plasma factor VIII levels were found to be a significant, independent risk factor for PE.     

Maastricht Ⅱ treatment scheme and efficacy of different proton pump inhibitors in eradicating Helicobacter pylori

AIM: The Maastricht Ⅱ criteria suggest the use of amoxicillin and clarithromycin in addition to a proton pump inhibitor over 7-10 d as a first line therapy in the eradication of Helicobacter pylori(H pylori). For each proton pump inhibitor, various rates of eradication have been reported. The present study was to compare the efficacy of different proton pump inhibitors like omeprazole, lansoprazole and pantoprazole in combination with amoxicillin and clarithromycin in the first line eradication of H pylori and to investigate the success of H pylori eradication in our district.METHODS: A total of 139 patients were included having a Helicobacter pylori(+) gastroduodenal disorders diagnosed by means of histology and urease test. Besides amoxicillin (1 000 mg twice a day) and clarithromycin (500 mg twice a day), they were randomized to take omeprazole (20 mg twice a day), or lansoprazole (30 mg twice a day), or pantoprozole (40 mg twice a day) for 14 d. Four weeks after the therapy, the eradication was assessed by means of histology and urease test. It was evaluated as eradicated if the H pylori was found negative in both. The complaints (pain in epigastrium, nocturnal pain, pyrosis and bloating)were graded in accordance with the Licert scale. The compliance of the patients was recorded.RESULTS: The eradication was found to be 40.8% in the omeprazole group, 43.5% in the lansoprazole group and 47.4% in the pantoprazole group. Sixty-three out of 139patients (45%) had eradication. No statistically significant difference was observed between the groups. Significant improvements were seen in terms of the impact on the symptom scores in each group.CONCLUSION: There was no difference between omeprazole, lansoprazole and pantoprazole in H pylori eradication, and the rate of eradication was as low as 45%.Symptoms were improved independent of the eradication in each treatment group. The iow eradication rates suggest that the antibiotic resistance or the genetic differences of the microorganism might be in effect. Further studies are required to verify these suggestions.     

Homocysteine levels in epileptic children receiving antiepileptic drugs

The aim of this study is to investigate the homocysteine, folic acid, and vitamin B(12) levels in epileptic children receiving antiepileptic drugs. A total of 25 children with idiopathic epilepsy (8 valproate, 11 carbamazepine, and 6 oxcarbazepine) and 10 healthy children were included in the study. The mean homocysteine, folic acid, and vitamin B(12) levels in the study group were 7.57 +/- 3.78 micromol/L (normal = 5-15 micromol/L), 10.19 +/- 4.05 ng/mL (normal = 3.0-17 ng/mL), and 428.20 +/- 256.12 pg/mL (normal = 193-983 pg/mL), respectively. The differences between the mean plasma homocysteine, folic acid, and vitamin B(12) levels of the study and control groups were not significant (P = .522; P = .855; P = .798, respectively). However, plasma homocysteine levels were higher than the normal cutoff point accepted for childhood in 4 (16%) of the study patients. Out of these 4 children, 3 were from the carbamazepine group and 1 was from the valproate group. Although the number of the study patients is limited, the authors recommend assessment of plasma homocysteine, serum vitamin B(12), and folic acid levels in children receiving enzyme-inducing antiepileptic drugs.     

Can strain elastography combined with ultrasound breast imaging reporting and data system be a more effective method in the differentiation of benign and malignant breast lesions?

Purpose

To investigate whether a novel method that combines breast imaging reporting and data system (BI-RADS) with strain elastography contributes to diagnostic performance in differentiation of malignant and benign breast lesions.

Methods

In 81 patients, 81 breast lesions were prospectively investigated. Breast lesions were separately evaluated with ultrasonography and strain elastography. While evaluations with ultrasonography were based on 2003 BI-RADS-US, strain elastography evaluations were based on a 5-point scale and strain ratio. Diagnostic performances of ultrasonography, strain elastography, and the combined method were compared.

Results

Among 81 lesions, 43 (53.1%) were benign and 38 (46.9%) were malignant. When a cutoff point of category 3 was used, sensitivity, specificity, positive and negative predictive values, and accuracy for BI-RADS were 100, 11.6, 50, 100, and 53%, respectively. When BI-RADS and strain ratio were combined, sensitivity, specificity, positive and negative predictive values, and accuracy were 89.5, 93, 91.9, 90.9, and 91.3%, respectively. When BI-RADS and elastography scores were combined, sensitivity, specificity, positive and negative predictive values, and accuracy were 86.8, 97.7, 97.1, 89.4, and 92.5%, respectively.

Conclusions

The combination of strain elastography and BI-RADS was found to have better diagnostic performances to diagnose breast lesions than BI-RADS alone.

     

Soluble epoxide hydrolase and epoxyeicosatrienoic acids modulate two distinct analgesic pathways

During inflammation, a large amount of arachidonic acid (AA) is released into the cellular milieu and cyclooxygenase enzymes convert this AA to prostaglandins that in turn sensitize pain pathways. However, AA is also converted to natural epoxyeicosatrienoic acids (EETs) by cytochrome P450 enzymes. EET levels are typically regulated by soluble epoxide hydrolase (sEH), the major enzyme degrading EETs. Here we demonstrate that EETs or inhibition of sEH lead to antihyperalgesia by at least 2 spinal mechanisms, first by repressing the induction of the COX2 gene and second by rapidly up-regulating an acute neurosteroid-producing gene, StARD1, which requires the synchronized presence of elevated cAMP and EET levels. The analgesic activities of neurosteroids are well known; however, here we describe a clear course toward augmenting the levels of these molecules. Redirecting the flow of pronociceptive intracellular cAMP toward up-regulation of StARD1 mRNA by concomitantly elevating EETs is a novel path to accomplish pain relief in both inflammatory and neuropathic pain states.
