To treat or not to treat, cheyne-stokes respiration in a young adult with vascular encephalopathy

HUBATSCH Mihaela, ENGLERT Harald, WAGNER Ulrich

Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing characterised by recurrent central sleep apnoea alternating with a crescendo-decrescendo pattern of tidal volume, relatively rare observation in sleep labs. It is mainly seen in severe heart failure and stroke. We report the case of a young man with CSR after sudden onset of seizure in the context of hypertensive exacerbation leading to the diagnosis of a leukoencephalopathy, and comment on differential diagnoses, prognostic and therapeutic outcomes. The very uniqueness of this case consists in the extremely young age for developing a vascular encephalopathy in the absence of genetic diseases and without previous diagnose of hypertension. There is no adequate explanation for the origin of vascular encephalopathy; also there is lack of evidence regarding the benefits and modality of treatment for CSR in neurologic diseases. Thus, we were forced to find the best compromise in a nocturnal oxygen therapy and follow-up.

[Thinking globally - the significance of the joint treatment of risk factors]

BENCZÚR Béla

[Hypercholesterolemia and hypertension - as the key risk factors of ischemic heart disease - are strongly linked to the increasing prevalence of cardiovascular mortality and morbidity. These risk factors are related to each other and half of the hypertensive patients have elevated cholesterol, as well. The recent European hypertension guidelines recommend statin treatment in dyslipidemic and/or subjects at high risk including diabetic or CKD-patients. Reaching blood pressure target if we can hold the patient under 1.8 mmol/l LDL-level results in 60% reduction of the risk of CAD and 17% reduction of stroke. This aim can only be reached if patients regularly take their prescribed medications although statinadherence is the poorest in our country. One of the main tools of improving adherence beyond education is the use of fix-dosed combination.]

[The evolution of skull reconstruction surgical techniques and it’s impact on patient’s care and the effect on patients from the nursing perspective]

VARGEK Anikó

[Background: Facts support that decompressive craniectomy allaviates life-threatening acute high intracranial pressure and it is performed worldwide. Less attention has been paid to the late negative consequences of the widely open cranium. Hence there is a need for timely closure of the defect and precise cranioplasty. Objective: The goal of the present study was to compare the clinical results and patient care data gained by a novel cranioplasty method, the so called computer-aided design and computer-aided manufacturing (CAD/CAM) technique, versus conventional operative procedures. Patients and Methods: Seventy patients were operated on by conventional reconstructive methods (n=70) in our department between 2004 and 2006. These patients served as the control group. Sixty patients had got cranioplasty with individually prepared cranial implants using the CAD/CAM technique (n=60) in 2011 to 2013. The total number of the investigated patient population was n=130. Age distribution of the group varied from 17 to 80. Retrospective neurological and patient care data were collected and compared at the two surgical technique. Results: More precise coverage of the cranial defect and acceptable cosmetic result were achieved in every case operated on with the CAD/CAM surgical technique. The ratio of patients with persistent vegetative-state decreased, and the neurological outcome improved following surgery using the CAD/CAM method. The patient care was easier and rehabilitation procedure was more favourable at the CAD/CAM population. Iatrogenic infection and wound- healing complications were less frequent at the department between 2011 and 2013. The quality of patient care have been improving considerably by regular education and continuous development of nursing standard. Patients need for hospital stay decreased, therefore health economic aspects and cost-benefit ratio improved at the Department of Neurosurgery in the Péterfy Hospital. Conclusion: This study demonstrates an improvement in neurological outcome and easier patient care following CAD/CAM reconstructive surgery of cranial defects in status of normalized intracranial pressure. Results support the extended use of the method in the XXI. Century. ]

FUSZ Katalin, KOVÁCS KALIC Károly, KÍVÉS Zsuzsanna, MÜLLER Ágnes, OLÁH András

[Aim of the study: Several physiological processes are disturbed in shift workers. The authors’s aim was to complete a pilot study as part of the validation process of Standard Shiftwork Index (SSI) and to examine the effects of shiftwork on the quality of sleeping and on psychical and somatic status. Sample and methods: The survey was implemented at the hospitals of the University of Szeged in 2011, with the participation of not randomly selected nurses working in shiftwork, night- or dayshifts (N=211). SSI was complemented with further respective questions. Results: Those working in dayshift suffer less from sleep disorders than nurses working in nightshift or shiftwork (p=0,002, p=0,005), and have better health status (p=0,001, p=0,003), furthermore feel themselves less tired (p=0,011, p=0,039). The nightshift workers had gastrointestinal complaints more frequently (p=0,044, p=0,006), as well as nurses working in nightshift suffer from more chronic diseases than dayshift workers (p=0,004) and shift workers (p=0,003). In case of shift workers the weekly amount of cigarettes having smoked (p=0,008) and the consumption of caffeinated refresher beverages (p<0,001) were significantly increased since the beginning of their shiftwork. Conclusion: Health status of nurses working in nightshifts and shiftwork are more relapsed, their health attitude is worse than in case of dayshift workers. As the continuation of this examination the authors try to find out which variations of shiftwork can be considered less exhausting.]

[The interactive neuroanatomical simulation and practical application of frontotemporal transsylvian exposure in neurosurgery]

BALOGH Attila, CZIGLÉCZKI Gábor, PÁPAI Zsolt, PREUL C. Mark, BANCZEROWSKI Péter

[Background and purpose - There is an increased need for new digital education tools in neurosurgical training. Illustrated textbooks offer anatomic and technical reference but do not substitute hands-on experience provided by surgery or cadaver dissection. Due to limited availability of cadaver dissections the need for development of simulation tools has been augmented. We explored simulation technology for producing virtual reality-like reconstructions of simulated surgical approaches on cadaver. Practical application of the simulation tool has been presented through frontotemporal transsylvian exposure. Methods - The dissections were performed on two cadaveric heads. Arteries and veins were prepared and injected with colorful silicon rubber. The heads were rigidly fixed in Mayfield headholder. A robotic microscope with two digital cameras in inverted cone method of image acquisition was used to capture images around a pivot point in several phases of dissections. Multilayered, high-resolution images have been built into interactive 4D environment by custom developed software. Results - We have developed the simulation module of the frontotemporal transsylvian approach. The virtual specimens can be rotated or tilted to any selected angles and examined from different surgical perspectives at any stage of dissections. Important surgical issues such as appropriate head positioning or surgical maneuvers to expose deep situated neuroanatomic structures can be simulated and studied by using the module. Conclusion - The simulation module of the frontotemporal transsylvian exposure helps to examine effect of head positioning on the visibility of deep situated neuroanatomic structures and study surgical maneuvers required to achieve optimal exposure of deep situated anatomic structures. The simulation program is a powerful tool to study issues of preoperative planning and well suited for neurosurgical training.]

[Tailored cranioplasty using CAD-CAM technology]

VITANOVICS Dusan, MAJOR Ottó, LOVAS László, BANCZEROWSKI Péter

[Objective - The majority of cranial defects are results of surgical intervention. The defect must be covered within resonable period of time usually after 4-6 week given the fact that the replacement of bone improve the brain circulation. Number of surgical techniques and materials are available to perform cranioplasty. Due to favorable properties we chosed ultra high molecular weight polyethylene as material. In this paper the authors show a procedure which allows tailored artificial bone replacement using state of art medical and engineering techniques. Methods - between 2004 and 2012, 19 patients were operated on cranial bone defect and a total of 22 3D custom- designed implants were implanted. The average age of patients was 35.4 years. In 12 patients we performed primary cranioplasty, while seven patients had the replacement at least once. Later the implants had to be removed due to infection or other causes (bone necrosis, fracture). All patients had native and bone- windowed 1 mm resolution CT. The 3D design was made using the original CT images and with design program. Computer controlled lathe was used to prepare a precise-fitting model. During surgery, the defect was exposed and the implant was fixed to normal bone using mini titanium plates and screws. All of our patients had control CT at 3, 6 and12 months after surgery and at the same time neurological examination. Results - Twenty-one polyethylene and one titanium implants were inserted. The average follow-up of the patients was 21.5 months, ranged from two to 96 months. We follow 12 patients (63.15%) more than one year. No intraoperative implant modifications had to be made. Each of the 22 implant exactly matched the bone defect proved by CT scan. No one of our patients reported aesthetic problems and we did not notice any kind of aesthetic complication. We had short term complication in three cases due to cranioplasty, subdural, epidural haemorrhage and skin defect. Conclusion - Polyethylene is in all respects suitable for primary and secondary cranioplasty. Combined with 3D CADCAM method excellent aesthetic and functional result was achieved. In our study no case of infection occured. Proper preoperative preparation is important.]

[Chronotherapy of hypertension - individualized treatment according to the circadian blood pressure profile]

SZAUDER Ipoly, UJHELYI Gabriella

[The circadian (24 h) rhythm shows great importance in the pharmacotherapy of hypertension. There is growing interest in how to best tailor the treatment of hypertensive patients according to the circadian blood pressure pattern of each individual. Significant administration-time differences are in the chronokinetics of antihypertensive medication. The therapeutic coverage and efficacy of different antihypertensive drugs are all markedly dependent on the circadian time of drug administration. Administration of ACE inhibitors, ARBs, doxazosin and aspirin at bedtime, as opposed to upon wakening, results in an improved diurnal/nocturnal blood pressure ratio (recommended for nondipper type of hypertension). Other antihypertensive medications: calcium channel blockers and β receptor blockers are non effective at the circadian blood pressure pattern. Chronotherapy provides a means of individualizing the treatment of hypertension according to the circadian blood pressure profile of patients and constitutes a new option to optimize blood pressure control and reduce the risk of cardiovascular disease and the risk of end organ injury.]

[Occurrence of cardiometabolic risk factors among shift workers]

JERMENDY György, NÁDASI Judit, HEGYI Ilona, VASAS István, HIDVÉGI Tibor

[INTRODUCTION - Shift workers have an impaired circadian rhythm, which might have an adverse effect on their health. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers (aged 25-66 years, with a minimal shift working experience of 5 years). METHODS - In total 481 workers (121 men, 360 women) registered by the occupational health service were enrolled in our study. Most participants worked in the light industry (58.2%) or in public service (23.9%). Following questionnaire-based data recording, anthropometric measurements and physical examination were performed and fasting venous blood sample was taken for measuring laboratory parameters. Data from shift workers (n=234, 54 men and 180 women, age: 43.9±8.1 years) were compared with those of day workers (n=247, 67 men and 180 women, age: 42.8±8.5 years). RESULTS - Compared with day workers, shift workers had bigger weight (76.6±16.1 vs 73.9±17.6 kg; p<0.05), higher BMI index (27.5±5.3 vs 26.0±4.9 kg/m2; p<0.01) and systolic blood pressure (123±19 vs 119±16 mmHg, p<0.01), and higher prevalence rate of diabetes (4.3 vs 1.2 %; p<0.05) and cardiovascular diseases (3.8 vs 0.8 %; p<0.05). In addition, the proportion of participants who performed regular physical activity was lower (20.6 vs 38.7 %; p<0.001) and that of current smokers were higher (35.0 % vs 19.5 %; p<0.001) in shift workers than in day workers. In laboratory findings, only one difference has been found: HDL-cholesterol level was lower among women (shift workers versus workers: 1.56±0.32 vs 1.68±0.36 mmol/l; p<0.01). CONCLUSION - Long-term shift work (day-night) results in a less healthy lifestyle and worse cardiometabolic risk factors compared with day work. Thus, our study highlights the importance of measures for preventing cardiovascular diseases in shift workers.]

SZÉKELY László, GYÖRGY Margit, JUHÁSZ Boglárka, SZABÓ J. Zoltán, SZUDI László, PAULOVICH Erzsébet, LONKAY Eszter, HORKAY Ferenc

[OBJECTIVE - Aging of the society results in important demographic changes in cardiac surgical practice. Controversy exists as to whether heart surgery in elderly patients improves their life expectancy and the severe functional restraint caused by their heart diseases. PATIENTS AND METHODS - We discuss a retrospective study of octogenarian patients who underwent cardiac surgical procedures in our institutions between 01.01.2000. and 30.06.2006. The mean age of the 105 participants was 81.5 years (80-87). 67% (70) of patients had coronary artery disease (CAD). 31% (33) of the patients had aortic valve stenosis (AVR), of whom 16 had isolated AVR and 17 had AVR combined with CAD. One patient had surgery because of mitral valve insufficiency (MVR) only, and one was treated for combined AVR and MVR. The average surgical euroscore was 9.7 (5-18) and the predictive mortalities were 18%. 9.5% of the procedures were acute, 42.9% were urgent and 47.6% were chronic surgeries. RESULTS - The average operating time was 149±23 min, duration of the aortic cross clamp was 65±11 min. OPCAB procedures were performed in 82.9% of patients treated for CAD. In the postoperative period, the occurrence of renal failure was 2.9%, blood transfusions were needed in 37.4% of patients, and neurological deficits occurred in 2.9% of patients. The incidence of perioperative myocardial infarction was 5.6%. The rate of early mortality was 4.8%, the rate of late (>30 days) mortality was 14.3%. At the last follow-up examination, 67 (79%) of the surviving 85 patients were free of cardiac symptoms, physically active and able to take care of themselves. 14 patients (17%) needed some help and only 4 patients (5%) were unable of taking care of themselves. CONCLUSIONS - The mortality of cardiac diseases can be reduced by cardiac surgeries in octagenerians. Improvement of cardiac symptoms improves the patients’ functional status and their quality of life can be similar to that of healthy people of the same age.]

[CADASIL and other hereditary small vessel diseases of the brain - Increasingly diagnosed conditions underlying familial ischaemic stroke and dementia]

GUNDA Bence, HUGUES Chabriat, BERECZKI Dániel

[CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) has recently gained great interest in vascular neurology as the most common heritable cause of stroke and vascular dementia in adults. This autosomal dominant small vessel disease of the brain - unlike the sporadic, hypertensive form - appears already in adult midlife in the absence of vascular risk factors with ischemic episodes and progressive dementia, its first manifestation can be migraine with aura, and is often associated with psychiatric disturbances. The magnetic resonance imaging (MRI) changes showing a characteristic pattern may precede symptoms by more than a decade. The identification of the mautation of the NOTCH 3 gene responsible for the disorder encoding a transmembrane receptor of vascular smooth muscle cells - has given great impetus on research to understand the molecular and vascular pathogenesis of the disease. The special importance of this latter lies in the fact that CADASIL provides a pure genetic model for subcortical cerebral ischemia and vascular dementia without the confounding factors of comorbidities and advanced age. Thus insights into CADASIL may help us better understand the more common sporadic forms as well. Moreover CADASIL is one of the best studied examples of secondary migraine. Currently we have far less knowledge on other forms of hereditary small vessel disease of the brain such as CARASIL, HERNS, CRV, HVR, PXE etc. Neurologists are becoming more and more familiar with CADASIL, and with the wider availability of MRI it is increasingly diagnosed. However the disorder is still probably underrecognised. This review aims to summarize our current knowledge on CADASIL with special emphasis on diagnostic and diffrential diagnostic points for the practising neurologist.]
