[Age-related macular degeneration is the leading cause of blindness in developed countries. In the last few years, new therapeutic approaches such as photodynamic therapy and intravitreal injections of vascular endothelial growth factor antagonists were introduced that do not only prevent disease progression but also give the hope of vision improvement. Of the new diagnostic methods, the use of optical coherence tomography improves diagnosis and also permits the qualitative measurement of therapeutic effects. Given the current high price of the new drugs and the need for frequent re-treatments, a significant increase in the economic burden of the disease is foreseeable.]

[ITRODUCTION - Primary tumours are defined unknown if, despite of the presence of histologically verified metastases, the site of origin cannot be revealed even with complex investigations. On average, 5% of patients with cervical lymph node metastases belong to this group. The incidence of cervical lymph node tumours increases with age, with more than 60% arising from malignancies in patients over 40. PATIENT AND METHODS - In this retrospective study, the authors review the history of 29 patients treated or examined in their department between January 2002 and November 2006 with the starting diagnosis of cervical lymph node metastasis from a primary tumour of unknown origin. All patients had a thorough physical examination, indirect upper respiratory tract endoscopy, and aspiration cytology. In the search for the primary tumour the use of both traditional X-ray studies and modern imaging techniques are justified. RESULTS - Of the 29 patients, five did not present after surgery, and one patient died. The location of the primary tumour could be determined in 12 of the remaining 23 patients during the follow-up period. These included the palatine tonsil in four cases, the lung in three patients, the lower pharynx in two patients, and one case each of the lingual radix, the larynx and the nasal pharynx. The histology of the metastases was mostly squamous cell carcinoma and they were located in the upper parajugular region. The investigation of the remaining patients is continued. CONCLUSION - In cases of cervical lymph node metastases that histologically turn out to be squamous cell carcinoma, the primary tumour should first be searched for in the head-and-neck region, followed by the lungs. On the other hand, high-grade nasopharyngeal carcinomas warrant the search in the Waldeyer ring. The authors emphasize the importance to keep the proper order of the diagnostic and therapeutic steps and to manage these patients in experienced institutions.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Introduction - Stroke is the third leading cause of death worldwide (following cardiovascular and cancer mortality) and associated with serious disability for the vast majority of patients. There is no salvage therapy for irreversibly damaged brain areas, improving the circulation of the surrounding hypoperfused territories may be associated with benefitial clinical states. Cerebral hypoperfusion may play a role in the pathogenesis of other kind of neurological diseases, improvement of global circulation may have a preventive effect on these conditions. Aims - The aim of our study was to review the experimental and clinical articles focusing on the role of vinpocetin in different neurological conditions. Results - Vinpocetin appears to have several different mechanisms of action that allow for its antiinflammatory, antioxidant, vasodilating, antiepileptic and neuroprotective activities in experimental conditions. On the other hand, several meta-analysis of the existing studies in acute stroke examining short and long term fatality rates with vinpocetin was unable to assess efficacy. In chronic cerebrovascular patients, vinpocetin improves impaired hemorheological variables, has significant vasodilating properties, improves endothelial dysfunction, neuroimaging studies showed selective increase in cerebral blood flow and cerebral metabolic rate, all of which are potentially beneficial in cerebrovascular disease and may improve cognitive functions. Summary - Based on the above mentioned results vinpocetin plays an important role both in basic research and in clinical management of different neurological diseases.]

The prevalence of sarcopenia and dynapenia according to stage among Alzheimer-type dementia patients

YAZAR Tamer, YAZAR Olgun Hülya

Aim - In this study, the aim was to identify the prevalence of sarcopenia and dynapenia according to disease stage among Alzheimer-type dementia (AD) patients and collect data to suggest precautions related to reducing the disease load. Method - The study was completed with 127 patients separated into stages according to Clinical Dementia Rating Scale (CDR) criteria and 279 healthy volunteers aged 18-39 years and 70-80 years abiding by the exclusion criteria who agreed to participate in the research. Our prospective and cross-sectional study applied the CDR and mini mental test (MMSE) to patients with disorder in more than one cognitive area and possible AD diagnosis according to NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association) diagnostic criteria. The patient and control groups had skeletal muscle mass index (SMMI), muscle strength and physical performance assessed with sarcopenia diagnosis according to European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria. Results - In our study, in parallel with the increase in disease stage of AD patients, the prevalence of sarcopenia (led by severe sarcopenia) and dynapenia was higher compared to a control group of similar age. Conclusion - In chronic, progressive diseases, like AD, identification of changes in parameters, like muscle mass and strength and reductions in physical performance in the early period, is important for identification and to take precautions in the initial stages considering the limitations of the preventive effects of treatment applied after diagnosis of AD.


[New findings in the cortical bone biology and its role in bone fractures]


[The authors surveyed the already known factors responsible for the osteoporotic bone fragility. Then the results of using modern imaging techniques (micro-CT, high-resolution peripheral computed quantitative tomograph - HR-pQCT) and advanced computer analytic methods (finite element analysis, FEA) are presented. These data - beyond the already known fracture risk factors (age, risk of falling, bone mineral density - BMD, and fine structure damage of trabecular bone) are stressing the importance of the (micro)damage of cortical bone as a fracture risk factor, which has been still underrated. The cortical thickening and increased porosity - verified on various population samples - are increasing the risk of fractures in certain subgroups of subjects having identical BMD values, even among those, who are considered only osteopenic by the earlier classification based on BMD values. Backed with modern software batteries, the new imaging techniques are expected to enter clinical application in the near future. Pharmacologic agents with stronger cortical effect are already available and research is continuing to find new drugs to use in the management of osteoporotic patients of high fracture risk.]

Purpose - Nonconvulsive status epilepticus (NCSE) is a heterogeneous, severe neurological disorder of different etiologies. In this study, the outcomes of NCSE episodes was assessed in a large series of adult patients. Our objective was to evaluate relationship between Status Epilepticus Severity Score (STESS) and etiology and the role of etiological factors on predicting the outcomes. Method - In this retrospective study, the medical records of 95 patients over 18 years of age who were diagnosed with NCSE between June 2011 and December 2015 were reviewed. Their treatment and follow-up for NCSE was performed at the Epilepsy Unit in Department of Neurology, Antalya Research and Training Hospital. Etiological factors thought to be responsible for NCSE episodes as well as the prognostic data were retrieved. The etiological factors were classified into three groups as those with a known history of epilepsy (Group 1), primary neurological disorder (Group 2), or systemic/unknown etiology (Group 3). STESS was retrospectively applied to patients. Results - There were 95 participants, 59 of whom were female. Group 1, Group 2, and Group 3 consisted of 11 (7 female), 54 (33 female), and 30 (19 female) patients, respectively. Of the 18 total deaths, 12 occurred in Group 2, and 6 in Group 3. The negative predictive value for a STESS score of ≤ 2 was 93.88% (+LR 2.05 95% CI: 1.44-2.9 and -LR 0.3 95% CI 0.10-0.84 ) in the overall study group. While the corresponding values for Group 1 (patients with epilepsy), Group 2 (patients with primary neurological disorder), and group 3 (patients with systemic or unknown etiology) were 100%, 92.59% (+LR 2.06 95%CI: 1.32-3.21 and -LR 0.28 95% CI 0.08-1.02 ) 83.33% (+LR 1.14 95%CI: 0.59-2.9 and -LR 0.80 95% CI 0.23-2.73). Conclusions - This study included the one of the largest patients series ever reported in whom STESS, a clinical scoring system proposed for use in patients with status epilepticus, has been implemented. Although STESS appeared to be quite useful for predicting a favorable outcome in NCSE patients with epilepsy and primary neurological disorders, its predictive value in patients with systemic or unknown etiology was lower. Further prospective studies including larger NCSE samples are warranted.
