[Systemic diseases in pseudoexfoliation syndrome]


[Pseudoexfoliation syndrome is a condition associated with the production and accumulation of a pathological protein (pseudoexfoliation material). Originally, the syndrome was recognised on the basis of its intraocular symptoms and had been considered to be an isolated eye disease for a long time. However, some 20 years ago it became clear that in pseudoexfoliation syndrome pseudoexfoliation material is present all over in the body. In the past decade, vascular dysfunction associated with this syndrome has been also recognised. Recent studies have shown that pseudoexfoliation syndrome is caused by genetic alterations affecting a lysil oxidaselike (LOXL) protein, LOXL1. LOXL1 has an important role in the synthesis of extracellular material. To our current knowledge, pseudoexfoliation syndrome is a systemic elastosis associated with oxidative stress. Its complications are in part ocular (development of nuclear cataract, zonular damage and development of pseudoexfoliative glaucoma) and in part systemic (dysfunction of capillaries, muscular and elastic arteries, impairment of baroreflex function, increase of arterial rigidity, development of aorta aneurism, recurrent venous occlusions and neurosensory hearing loss). Despite the recognition of the above complications, currently it is not possible to set guidelines of a potential cardiovascular screening for patients with pseudoexfoliation syndrome, since the frequency and significance of systemic complications vary across different populations.]

[Hypertension in the elderly - critical review of diagnostic-therapeutic guidelines and their background]


[In the majority of old and very old hypertensive patients, the reduction of abnormally high blood pressure has been proved to provide a strategic defense of target organs. In patients younger than 80 years, both initial and target blood pressure (BP) values are similar to those of younger age groups. In those older than 80 years, a a systolic blood pressure level >160 mmHg is the threshold of indication for antihypertensive treatment and the therapeutic target value is<150 mmHg. Both values are evidence- based (HYVET). The latest ACCF/AHA guidelines (USA 2011) advise to achieve a BP below 140 mmHg if the use of one or two antihypertensive agents result in sufficient BP reduction. However, this strategy is not yet supported by unequivocal evidence regarding complications in target organs. It is not recommended to aim for target levels lower than the above values (especially the value defined by the ESH guidelines) even in elderly hypertensive patients at high cardiovascular risk, as the results of several studies suggest a J-curve effect. In multimorbid elderly patients it is highly important to adapt antihypertensive treatment to individual needs, rather than to use schematic approaches. The number and progression of comorbid diseases can greatly influence, in certain cases attenuate the aimed BP reduction. A similar medical decision should be made if the target BP level could only be achieved by the combination of multiple antihypertensive medications, which can remarkably impair quality of life in elderly patients. Among non-comorbid elderly patients with hypertension, there seems to be no convincing difference in the efficiency of target organ protection between antihypertensive treatments that have different target sites but can achieve similar target levels. However, the majority of elderly hypertensive patients have comorbidities with variable rates of progression. In those at even low cardiometabolic risk the use of beta-receptor blockers (BRB) and especially a combination of BRB+diuretic (DIU) is not recommended. The adequate therapeutic tactic includes the use of only moderate drug-doses and their early combination. This approach has been convincingly proved mainly with early combinations of RAS inhibitors+CCB-s and RAS inhibitors+small doses of DIU-s. It is very important to monitor the treated patients, as the BP and circulatory response to the same antihypertensive treatment can markedly change in elderly patients when either the enviromental conditions change or a new pathologic process develops and/or is treated. Strict control is also necessary because it occurs quite often that the earlier optimal compliance of elderly patients in taking antihypertensive medicines rapidly deteriorates. The efficiency of statins and acetylsalicylic acid decreases over 80 years of age, but this does not indicate that the previously efficient approach should be suspended.]

[Rosuvastatin for the treatment of diabetic dyslipidaemia]


[Cardiovascular disease is a leading cause of death. The incidence of type 2 diabetes is increasing worldwide as well as in Hungary. Diabetes mellitus is a high-risk state, and if associated with coronary disease, it is considered a very high-risk condition. According to the 5th Cardiovascular Consensus Conference and ESC/EAS, the target level of LDL-cholesterol should be <2.5 mmol/l in high-risk condition and <1.8 mmol/l in very high-risk condition. In diabetes, one of the main goals is to achieve target LDL-cholesterol levels, which require lifestyle changes as a first step, followed by statin treatment, in combination with with ezetimibe if necessary. Statins are also known to have diabetogenic effects, which are dose-dependent. The advantage of the preventive cardiovascular effects observed in nondiabetic patients substantially outweighs the risk of potentially developing diabetes mellitus, therefore, this risk should not hinder the use of statins. Statin treatment can substantially reduce cardiovascular events in patients with diabetes mellitus. The greatest reduction in LDL-cholesterol level can be achieved by the most efficient statin, rosuvastatin.]

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

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.

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

A rare entity of acquired idiopathic generalised anhidrosis which has been successfully treated with pulse steroid therapy: Does the histopathology predict the treatment response?

ÖKTEM Özdemir Ece, ÇANKAYA Şeyda, UYKUR Burak Abdullah, ERDEN Simsek Nazan, YULUG Burak

Acquired idiopathic generalised anhidrosis is an uncommon sweating disorder characterized by loss of sweating in the absence of any neurologic, metabolic or sweat gland abnormalities. Although some possible immunological and structural mechanisms have been proposed for this rare entity, the definitive pathophysiology is still un­clear. Despite some successfully treated cases with systemic corticosteroid application, the dose and route of steroid application are controversial. Here, we present a 41-year-old man with lack of genera­lised sweating who has been successfully treated with high dose pulse intravenous prednisolone. We have discussed his clinical and histopathological findings as well as the treatment options in view of the current literature.
