Use of home sphygmomanometers in Turkey: a nation-wide survey

The purposes of this study were to detect the prevalence of ownership of a home sphygmomanometer among hypertensive subjects through a nation-wide survey, to investigate parameters affecting ownership of a sphygmomanometer, to compare how home blood pressure monitoring (HBPM) was actually used in daily practice with some aspects of the current guidelines, and to discuss what we implemented to increase the reliability of HBPM in a developing country. A total of 2747 hypertensive patients from 34 cities, representative of the Turkish population, were enrolled in the study. A multiple-choice questionnaire was administered to each participant using the computer-assisted telephone interviewing method. Among 2747 hypertensive patients, 1281 of them (46.6%) had a home sphygmomanometer. Most of the patients were using wrist devices. The factors associated with ownership of a sphygmomanometer were female gender, older age, obesity, higher educational status, higher income level, living in urban areas, awareness of hypertension and anti-hypertensive drug usage. Only 16% of the devices were used on the advice of a physician. The patients learned usage of their device mainly from the sellers and their relatives. The ownership of a home sphygmomanometer is common among hypertensive patients in Turkey, but regular monitoring of blood pressure before physician visits is rare despite common ownership of these devices. Daily practice of HBPM in Turkey was far from the recommendations of the current guidelines. More effort is needed to improve the reliability of HBPM.     

Waist circumference is associated with carotid intima media thickness in peritoneal dialysis patients

Purpose

Atherosclerosis is responsible for the high mortality rate in end-stage renal disease patients. Defining risk factors for atherosclerosis may lead to reduction in cardiovascular disease through modification of these factors. Peritoneal dialysis (PD) patients are subjected to high glucose loads on a daily basis, which results in considerable weight gain and an increase in waist circumference (WC). WC as an indicator of abdominal obesity is a risk factor for atherosclerosis in the general population. Carotid artery intima media thickness (CIMT) measurement is a reliable method for the detection of early atherosclerosis. The aim of this study was to investigate the relationship between WC and CIMT and to define risk factors associated with CIMT in PD patients.

Methods

Fifty-five PD patients and 40 healthy controls were included. Atherosclerosis was assessed using measurement of CIMT. Fasting blood was collected for analysis. Anthropometric parameters (age, weight, BMI, and WC) were measured.

Results

Peritoneal dialysis patients had higher WC (93.9 ± 1.7 vs. 87.3 ± 1.2 cm, p < 0.05) and CIMT (0.70 ± 0.02 vs. 0.57 ± 0.01 mm, p < 0.01) than the control group. On univariate analysis, age, WC, plaque formation, and D/P creatinine were positively correlated with CIMT, whereas residual renal function, albumin, ultrafiltration volume, and D/D0 glucose were negatively correlated. On multivariate analysis, only age, WC, and plaque formation showed correlation (p < 0.001).

Conclusions

Carotid artery intima media thickness is associated with age, plaque formation, and WC in PD patients. WC measurement is a simple, inexpensive, reproducible, and reliable method of evaluating atherosclerosis risk in PD patients and should be assessed at every visit. Appropriate counsel should be provided to patients with greater WC who are deemed to be at risk for atherosclerosis.     

Avaliação de entesopatia em pacientes com fibromialgia por meio do novo índice ultrassonográfico de entesite

ObjectiveThe aim of the present study is to determine the frequency of enthesopathy in fibromyalgia (FM) by using a newly developed ultrasonography (US) method, the Madrid Sonography Enthesitis Index (MASEI).MethodsThis study was conducted on 38 consecutive patients with FM and 48 healthy sex- and age-matched controls. Six entheseal sites (olecranon tuberosity, superior and inferior poles of patella, tibial tuberosity, superior and inferior poles of calcaneus) on both lower limbs were evaluated. All US findings were identified according to MASEI. Scores of patients and controls were compared by Student's t-test and Mann-Whitney U-test. Validity was analysed by receiver operating characteristic curve. Values of P < 0.05 were considered significant.ResultsTotal enthesitis score was 7.39 ± 4.99 (mean ± SD) among FM patients and 3.7 ± 3.22 among healthy controls (P < 0.001). The receiver operating characteristic curve established an ultrasound score of > 3.5 in the FM group as the best cut-off point to differentiate between cases and controls. No statistically significant correlation was found between the MASEI score and the FM disease duration, and the location of the tender points.ConclusionsMisdiagnoses of FM are harmful to patients and the community, and the presence of enthesopathy among FM patients increases. Its detection with the MASEI score may help to discriminate FM patients presenting with ill-defined symptoms and signs, in order to prevent mistreatment.     

A Case of Kaposi's Sarcoma Following Treatment of Membranoproliferative Glomerulonephritis and a Review of the Literature

Kaposi's sarcoma (KS) is an unusual tumor principally affecting the skin of the lower extremities. Although the association between KS and renal transplant has been well documented, there are a few KS cases in the literature associated with membranoproliferative glomerulonephritis or other glomerular diseases. This report presents a patient with membranoproliferative glomerulonephritis (MPGN) who developed KS following treatment with long-term medium dose glucocorticoid and short-term additional immunosuppressives. The KS cases associated with glomerulonephritis are also reviewed. KS is a rare complication in glomerular diseases that may (or may not) be related to immunosuppression. Hence, immunosuppression treatment should be carefully planned in glomerulonephritis treatment and avoided if they are not essentially necessary.     

Obstruction of mechanical mitral valves by preserved posterior leaflet remnants

We report two cases of mechanical prosthetic mitral valve obstruction caused by remnants of the mitral valve posterior leaflet tissue preserved from the previous surgery. Both patients had rheumatic mitral stenosis causing New York Heart Association class III symptoms prior to mitral valve replacement.     

Relationship of olfactory function with olfactory bulbus volume,disease duration and Unified Parkinson’s disease rating scale scores in patients with early stage of idiopathic Parkinson’s disease

We aimed to investigate the relationship between olfactory function and olfactory bulbus (OB) volume, disease duration and Unified Parkinson’s disease rating scale (UPDRS) scores in early stage idiopathic Parkinson’s disease patients. The University of Pennsylvania Smell Identification Test (UPSIT) was used for the evaluation of olfactory function. UPSIT scores for patients with Parkinson’s disease were significantly lower than controls. There was no significant difference between stage 1 and stage 2 patients. OB volumes were higher in stage 1 and 2 patients than controls, but there was no statistical difference between the three groups. No significant correlation was found between UPSIT and UPDRS total scores, nor between UPSIT scores and disease duration in stage 1 and 2 patients. According to our results, we propose UPSIT be used as a screening test to diagnose presymptomatic patients, but not OB volumes.     

Predictors of Intractable Childhood Epilepsy

Our study sought to identify early predictive factors of medically intractable childhood epilepsy. A cohort of epileptic children from the city of Mersin was retrospectively investigated. All patients received care from the same Department of Pediatric Neurology. The epileptic cohort was divided into a drug-responsive epilepsy group and an intractable epilepsy group. Intractable epilepsy is defined as continued seizures in children despite adequate therapy with two or more antiepileptic drugs for more than 18 months. Strong univariate association was observed between intractability and several factors: age of onset, high initial seizure frequency, symptomatic etiology, mixed seizure types, previous history of status epilepticus, febrile and neonatal seizures, mental and motor developmental delay, multiple seizures in 1 day, electroencephalogram abnormalities, magnetic resonance imaging findings, and specific epileptic syndromes. Logistic regression analysis revealed that a previous history of epilepticus status, abnormal electroencephalogram results, and multiple seizures in 1 day comprise independent predictors of medically intractable childhood epilepsy. We suggest that medical intractability in childhood epilepsy can be predicted by monitoring these factors. Along with early prediction, alternative therapies may be designed to provide patients better seizure control and quality of life.     

A platinum blue complex exerts its cytotoxic activity via DNA damage and induces apoptosis in cancer cells

Here, we describe the characteristics of a Pt‐blue complex [Pt₄(2‐atp)₈(H₂O)(OH)] (2‐atp: 2‐aminothiophenol) as a prodrug for its DNA‐binding properties and its use in cancer therapy. The nature of the interaction between the Pt‐blue complex and DNA was evaluated based on spectroscopic measurements, the electronic absorption spectra, thermal behavior, viscosity, fluorometric titration, and agarose gel electrophoresis. Our results suggested that the compound was able to partially intercalate DNA and appeared to induce both single‐ and double‐stranded breaks (DBS) on DNA in vitro, but no DSBs in cells. The ability of the compound to induce DNA damage was dependent on reactive oxygen species (ROS) in vitro. There was also elevated formation of ROS and SOD expression in response to drug treatment in cell culture. The complex was found to be more cytotoxic to cancer cells in comparison with noncancer controls using WST‐1 assay. The mean of cell death was determined to be apoptosis as assessed via biochemical, morphological, and molecular observations, including DNA condensation/fragmentation analysis, live cell imaging microscopy, TUNEL analyses, and increase in the levels of pro‐apoptotic genes such as Bag3, Bak, Bik, Bmf, and Hrk. Hence, the Pt‐blue complex under study grants premise for further studies.
