[Authors present the guidelines, indications and utility value of home selfmeasurements of blood pressure. They report the results of the most important clinical studies. They analyze the methodology of the measurements within telemedicinal solutions and describe the consultative scopes associated with the measurement methods already applied in clinical practice. Their own telemonitoring system - called Medistance - is then presented. They have created three modules for the long term registration of blood pressure in hypertensive patients: 1. an individual module for the hypertensive patients, the elderly, the family, for patients with high cardiovascular risk and for the physicians. 2. a module for the pharmaceutical care, 3. a module for the communities (social homes, club for the elderly, etc.). The Medistance system is functioning for two years in our count]

[The improvement of the rate of reaching the target blood pressure and the quality of care of hypertensive patients with applying telemedicine facilities]

KISS István, KÉLES Ede

[The authors summarize the facilities of the telemedicine and telemonitoring system. The methods of telemedicine and their combination with home blood pressure measurement or the help of a nurse or pharmacist are reviewed. In the light of the latest results the authors are led to the conclusion that the intensive spread of using the facilities of telemedicine is necessary in the present-day Hungarian healthcare system. At the same time it is also determined that the methodical and technical potential is not enough to further enhance the efficiency in itself. The personal contact and the possibility of interactive monitoring from distance are definitely crucial for the continuous maintenance of the reached target blood pressure in patients suffering from hypertension and also for the augmentation of patient adherence regarding applying medicine.]

[Molecular mechanisms leading to renal fibrosis: the origin of myofibroblasts]

HIMER Leonóra, SZIKSZ Erna, KOVÁCS Krisztián, ÓNODY Anna, Reusz György, FEKETE Andrea, TULASSAY Tivadar, VANNAY Ádám

[There are about a quarter of million patients who need chronic renal replacement therapy in Europe, and the estimated number of patients with chronic kidney disease is about tenfold higher. Interestingly, regardless of the initiating cause the mechanism of fibrosis is similar to each other in the different chronic kidney diseases. In general, the damaged glomerular or tubular cells release danger signals and produce chemotactic stimuli, which trigger the rapid recruitment of leukocytes. The infiltrating immune cells and the damaged renal cells then produce high levels of proinflammatory cytokines, growth factors, chemokines and adhesion molecules which contribute to glomerular/tubular injury, accumulation of further leukocytes and myofibroblasts, which are the effector cells of renal fibrosis. However the origin of myofibroblasts is still controversial. Recent hypotheses suggest that they are originated from different renal cells, such as epithelial and endothelial cells, pericytes or bone marrow derived fibrocytes. The myofibroblasts thus generated serve as key cellular mediators of renal fibrosis. Myofibroblasts have migratory capacity, are resistant to apoptosis, produce several growth factors and cytokines and according to our present knowledge these cells are the main source of collagen-I and -III rich extracellular matrix in the fibrous tissue. Organ fibrosis is characterized with excessive deposition of extracellular matrix leading to glomerular sclerosis and renal tubulointerstitial fibrosis. The excessive deposition of fibrous tissue replaces healthy kidney tissue; nephrons disappear and kidney function declines gradually. In this article the knowledge is summarized on the molecular changes leading to the generation of renal myofibroblasts.]

[Measurement and value of blood pressure variability in increasing the number of patients reaching target blood pressure goal in hypertension]

KÉKES Ede, JÁRAI Zoltán, PAKSY András, KISS István

[The authors evaluate the indexes and their usefulness of the short term (ABPM), medium and long term measurement of the blood pressure variability in the care phase of the hypertensive population in Hungary by using a one-year multicentre prospective observational study. The population was split into two parts: in the active group, telemedicine tools were used to maximize the patientphysician relationship and patient education, their own activity. In the non-active group, traditional care took place. Among these, 6725, 18-64 years and 1005, 65 + years of hypertensive patients were analysed. At the start of the study, ABPM was performed in 243 cases. 1407 diabetic hypertensive patients were compared to non-diabetic patients. They have analysed previous international and domestic experiences. In the present study, the reduction of systolic and diastolic blood pressure variability was successful and significant in the 18-64 age group during the whole patients’ care phase, but a larger systolic variability reduction in the active group was achieved. In the 65+s, the systolic variability reduction was found to be significant, but the variability indexes in the active group were also smaller. In the 65+s, the diastolic variability did not change significantly in either group. In diabetic hypertension, variability indices were only reduced to 12 months. It could be clearly demonstrated that a high-level physician patient relationship has a beneficial effect on blood pressure fluctuation in hypertensive patients.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm


The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.
