Red cell distribution width and inflammation in patients with non-dipper hypertension.

Red cell distribution width (RDW) is independently associated with morbidity and mortality in cardiovascular diseases. RDW is elevated in hypertensive patients compared with normotensives. Based on the nocturnal course, hypertension classified as dipper and non-dipper. Non-dipper hypertension is associated with higher inflammation and worse prognosis. We aimed to investigate whether RDW and high-sensitive C-reactive protein (hsCRP) are elevated in non-dipper hypertensive patients compared with dippers. The study included total 247 essential hypertensive patients. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) was performed for each patient. Thereafter patients were divided into the two groups on the basis of the results of 24-h ABPM: 127 dipper hypertensives and 120 non-dipper hypertensives. Complete blood count and biochemistry were measured by standard methods and hsCRP was assessed by using BN2 model nephelometer. Non-dippers had significantly higher RDW levels than dippers [14.6 (13.8-17.0) vs 13.0 (12.5-13.4), p < 0.001, respectively]. After adjustment for hemoglobin, low-density lipoprotein-cholesterol, sex, age and hs-CRP, mean RDW values were for dipper and non-dippers 13.4 (12.4-13.2) and 14.5 (13.7-16.8), respectively (p < 0.001). RDW was negatively correlated with the percentage decline of systolic and diastolic BP from day to night (r = - 0.392, p < 0.001 and r = - 0.294, p < 0.001, respectively). Serum hsCRP levels were also significantly higher in the non-dippers (p < 0.001) and it was significantly positively correlated with RDW (r = 0.403, p < 0.001). In receiver-operating characteristic curve analysis, the optimal cut-off value of RDW to predict non-dipping pattern was > 13.8%, with 80% sensitivity and 75% specificity. RDW is significantly increased in patients with non-dipper hypertension compared with the dipper hypertension. Inflammatory activity was closely related to RDW in non-dipper hypertensives. RDW, as easy and quick measurable tool, can predict non-dipping pattern in essential hypertension.

[Primary percutaneous coronary intervention for acute myocardial infarction in elderly aged 75 years and over: in-hospital mortality and clinical outcome]. / Yetmis bes yas ve üstündeki akut miyokart enfarktüslü hastalarda primer perkütan girisim: Hastane içi mortalite ve klinik sonuçlari

OBJECTIVES: We aimed to determine the in-hospital mortality and clinical outcome of patients older than 75 years who were admitted to our high-volume tertiary center with ST-elevation myocardial infarction (STEMI) and treated with primary percutaneous intervention (PCI). STUDY DESIGN: Our study included patients over 75 years old who were admitted with STEMI and underwent primary PCI at our center between January 2008 and September 2011. We retrospectively collected data from our hospital records for 1165 patients with STEMI. We found 186 patients that were eligible for our study. We defined major adverse cardiovascular events (MACE) as in-hospital mortality, repeated target vessel revascularization, and reinfarction. RESULTS: The mean age of the patients was 79.7±4.4 years and the mean pain-balloon inflation time was 4.7±2.3 hours. The procedure success rate was 71.5%. In-hospital mortality and MACE occurred in 20.4% and 25.8% of patients, respectively. Twenty patients had cardiogenic shock at admission. Patients with cardiogenic shock had significantly more MACE than the rest of the study population (76.5% vs. 17.5%, p<0.0001). Independent predictors of MACE included Killip class at admission (OR 4.98, 95% CI 1.25-19.8, p=0.02), white blood cell counting (OR 1.15, 95% CI 1.0-1.3, p=0.04), development of in-hospital heart failure (OR 3.34, 95% CI 1.07-10.58, p=0.04), the presence of atrioventricular block in the hospital (OR 3.98, 95% CI 1.09-14.5, p=0.04), and the TIMI flow rate after primary PCI (OR 3.42, 95% CI 1.19-10.76, p=0.04). CONCLUSION: Our study revealed a high rate of MACE in patients older than 75 years admitted with STEMI regardless of undergoing primary PCI.

Massive pericardial effusion as the primary manifestation of high-grade malignant lymphoma.

Pericardial effusion might be the first presentation of various pathologies including malignant tumors. Massive pericardial effusion as the primary manifestation of high-grade malignant lymphoma is a very rare condition. A 53-year-old woman presented with progressive dyspnea of one-week history. Physical examination showed venous distention of the neck veins and diminished heart sounds. The chest X-ray demonstrated increased cardiothoracic index. Transthoracic and transesophageal echocardiographic examinations showed massive pericardial effusion without any other pathology. Hematologic and biochemical tests showed only anemia. The patient underwent pericardiocentesis. Pericardial adenosine deaminase test and cultures were negative. Cytopathologic examination of the fluid showed huge lymphocytes and highly atypical lymphoid cells consistent with high-grade malignant lymphoma (non-Hodgkin's lymphoma). Immunohistochemical analysis showed positivity for leukocyte common antigen. No other primary origin could be determined.

Acute subdural hematomas caused by ruptured aneurysms: experience from a single Turkish center.

AIM: Although an aneurysmal rupture typically presents on computed tomography (CT) imaging as only a subarachnoid hemorrhage (SAH), it may be associated with spontaneous (nontraumatic) subdural hemorrhage (sSDH). The purpose of this paper is to discuss the clinical and radiological characteristics, as well as a potentially dangerous situation in the diagnosis and the management of this life-threatening condition. MATERIAL AND METHODS: The Department of Neurosurgery at Inonu University (Turgut Ozal Medical Center) (TOMC) maintains a prospective database of all patients treated for intracranial aneurysms since 1999. Using this database, we obtained patients with ruptured aneurysms who presented with sSDH on CT imaging. RESULTS: 687 patients with radiographically documented ruptured aneurysms were admitted from January 2000 through January 2009. Of these, eleven patients presented with sSDH. The incidence of aneurysmal rupture with sSDH is 1.6 % in our series. CONCLUSION: Acute sSDH on cranial CT should be considered for an urgent workup of a ruptured aneurysm, even in the absence or presence of SAH finding. CT angiography has advantages over cerebral digital substraction angiography (DSA) and may be a reasonable alternative to latter modality in the diagnosis, triage, and treatment planning in patients with sSDH.

Severe main coronary artery disease in a young woman with ankylosing spondylitis.

Patients with ankylosing spondylitis (AS) have an approximately two-fold increased death rate compared to the general population, which is predominately caused by increased cardiovascular risk. The prevalence rate for myocardial infarction is approximately 2-3 fold increased as compared with the general population. The inflammatory process appears to have an important role in causing this excess cardiovascular risk. In this paper, we present a case of severe coronary artery disease which could be demonstrated clearly by computer tomography in a 27-year-old woman who is being followed with AS.

Evaluation of atrial vulnerability immediately after radiofrequency catheter ablation of accessory pathway in patients with Wolff-Parkinson-White syndrome.

PURPOSE: The intrinsic atrial vulnerability is proposed as one of the mechanisms of paroxysmal atrial fibrillation (PAF) in Wolff-Parkinson-White (WPW) syndrome. In this study, we examined the early changes in atrial refractoriness and intra- and inter-atrial conduction times after radiofrequency (RF) catheter ablation of accessory pathway (AP). METHODS: Twenty-four consecutive patients with WPW syndrome and documented AV reciprocating tachycardia but without history of PAF (fourteen male, mean age 39 +/- 9.5 years) and 27 control subjects (six female, mean age 51.4 +/- 10.1 years) with AV nodal reentrant tachycardia (AVNRT) who underwent ablation of the slow AV nodal pathways were enrolled into the study. Regional atrial effective refractory periods (AERPs), AERP dispersion, and intra- and inter-atrial conduction times were obtained before and 30 min after ablation and were compared between two groups. In the study group, patients with and without inducible AF were also compared regarding these parameters. RESULTS: In the study group, AERPs in higher right atrium and right posterolateral atrium were significantly increased, and AERP dispersion, intra-atrial, and inter-atrial conduction times were significantly decreased after ablation; AERP in distal coronary sinus was unchanged. In control group, no significant difference was observed in these parameters. Inducibility of AF was significantly reduced following ablation of AP in the study group (from seven to zero of 24 patients, p = 0.016). Comparison between patients with (n = 7) and without (n = 17) AF revealed that left atrium diameter was larger, AERPs in the right posterolateral atrium before and after ablation, and ERP of AP were shorter in AF group. CONCLUSION: In WPW syndrome patients, RF catheter ablation of AP results in an 'immediate' decrease in atrial vulnerability. Since inducibility of AF becomes more difficult in this less vulnerable atrium, the AP itself may play an important role in the development of AF.

Neuroprotective effect of mexiletine in the central nervous system of diabetic rats.

Both experimental and clinical studies suggests that oxidative stress plays an important role in the pathogenesis of diabetes mellitus type 1 and type 2. Hyperglycaemia leads to free radical generation and causes neural degeneration. In the present study we investigated the possible neuroprotective effect of mexiletine against streptozotocin-induced hyperglycaemia in the rat brain and spinal cord. 30 adult male Wistar rats were divided into three groups: control, diabetic, and diabetic-mexiletine treated group. Diabetes mellitus was induced by a single injection of streptozotocin (60 mg/kg body weight). Mexiletine (50 mg/kg) was injected intraperitoneally every day for six weeks. After 6 weeks the brain, brain stem and cervical spinal cord of the rats were removed and the hippocampus, cortex, cerebellum, brain stem and spinal cord were dissected for biochemical analysis (the level of Malondialdehide [MDA], Nitric Oxide [NO], Reduced Glutathione [GSH], and Xanthine Oxidase [XO] activity). MDA, XO and NO levels in the hippocampus, cortex, cerebellum, brain stem and spinal cord of the diabetic group increased significantly, when compared with control and mexiletine groups (P < 0.05). GSH levels in the hippocampus, cortex, cerebellum, brain stem and spinal cord of the diabetic group decreased significantly when compared with control and mexiletine groups (P < 0.05). This study demonstrates that mexiletine protects the neuronal tissue against the diabetic oxidative damage.
