N？ropsikiyatri Ar？ivi , 2012,
Abstract: The opercular syndrome is also known as Foix-Chavany-Marie syndrome and also as facio-labio-pharyngo-glosso-laryngo-brachial paralysis or the cortical type of pseudobulbar paralysis. This rare neurological entity generally develops secondary to cerebrovascular accidents affecting the bilateral opercular regions, usually as a result of subsequent strokes. In this paper, we describe a 74-year-old woman who presented with acute onset of inability to speak and swallow. Neurological examination revealed bilateral palsy of lower motor cranial nerves with preservation of reflex and automatic movements. Magnetic resonance images of the brain demonstrated an acute left opercular infarction. This syndrome usually occurs due to bilateral opercular lesions, nevertheless, the typical features of the syndrome may develop as a result of unilateral opercular lesion.

Abstract: Objective: Several studies have identified impaired performance on the cognition test in people with multiple sclerosis (MS), yet uncertainty remains over the cause of this impairment. The aim of this study was to evaluate the correlation of serum uric acid (UA) level with cognitive impairment and magnetic resonance imaging (MRI) lesions in patients with relapsing-remitting multiple sclerosis (RRMS).Methods: In this study, 50 adults patients with RRMS (disease period 1-5 years) were assessed with neuropsychological test batteries and laboratory blood studies. All the patients were subjected to oranial MRI examination and clinical evaluation with the expanded disability status scale (EDSS) was applied. Results: Cognitive impairment was found in 44% of the patients. Mean UA serum level was measured as 4.38±1.60 mg/dl (2-9 mg/dl) and the mean EDSS score was 2.09±2.01 (0-7). Even it is not statistically significant, the relation between serum UA level and cognitive functions or number of plaques on MRI was found at about statistically significant level (p=0.09). A statistically significant correlation was observed between the scores of the concentration and distractibility subtest scores of the ADAS-cog test and the serum UA levels (p=0.01). However, the effects of exhaustion and emotional disorders on this relation can not be excluded.Conclusion: Our findings suggest that in RRMS patients there is no primary deficit in serum uric acid. Cognitive impairment and total MRI lesion load in RRMS patients are not directly effected by serum UA level. (Archives of Neuropsychiatry 2010; 47: 333-7)

Abstract: Carbon monoxide (CO) intoxication can be a deadly condition and is a very common public health problem in Turkey due to the use of coal stoves during the winter months in homes. Carbon monoxide intoxication accounts for more than half of the deaths due to intoxications in Turkey. It is very likely to misdiagnose the cases of delayed anoxic encephalopathy (DAE) which are seen after the latent period following the acute intoxication. In delayed anoxic encephalopathy, following complete recovery and after a latent period, neurologic and/or psychiatric symptoms appear again. The symptom triad of DAE is mental deterioration, urinary and/or gaita incontinence and gait disturbances. The psychiatric appearance in DAE can be seen in a variety of very different findings including dementia, amnestic syndromes, organic affective disorders, personality disorders and psychosis. In this case report, we present a 35-year-old man, who was admitted to the hospital because of irritability and loose mind. The patient did not have any previous psychiatric or neurologic disorder, but he had CO intoxication 33 days before the admission and was discharged from the hospital following a hyperbaric oxygen treatment with a complete recovery. After a 15-day latency period he was admitted to the hospital because of the mentioned symptoms. The differential diagnosis of the rich neuropsychiatric findings together with cranial magnetic resonance imaging findings (MRI) are discussed in this patient.

Abstract: Introduction and Objective: Uric acid is a natural anti-oxidant that plays a role in acute oxidative stress reactions like acute ischemic stroke. In this study, we aimed to search the relation between serum uric acid level, length of hospital stay and severity of stroke in acute stroke patients, and consequently, the prognostic value of serum uric acid level.Patients and Methods: We performed a retrospective study on 100 patients who had presented to the emergency department with the findings of acute ischemic stroke. All the laboratory, radiological and clinical investigations were recorded. All the risk factors, National Institute of Health Stroke Scale (NIHSS), laboratory values, clinical findings, length of hospital stay of the patients and the treatment modalities were recorded.Results: The median serum uric acid level was 5.25±2.03 mg/dl. The median level in females was found to be higher than that in males. The length of hospital stay varied from 2 to 57 days and the median value was 13±8.66 days. In the multivariate analysis, increases in the levels of serum uric acid measured were significantly associated with decreased length of hospital stay. We detected a low value correlation between NIHSS and serum uric acid levels, but it was statistically insignificant. According to our results, there was a strong negative correlation between serum uric acid levels and the length of hospital stay, and a weak correlation between the serum uric acid level and the severity of stroke.
Methanol Poisoning and Putaminal Hemorrhage: Case Report
Hava D？NMEZ KEKL？KO？LU,Tahir KURTULU？ YOLDA？,Y？ld？z ？ORUH
Journal of Neurological Sciences , 2007,
Abstract: Methanol is a highly toxic substance used as an industrial solvent and automotive antifreeze. The central nervous system and the visual pathway are the main targets of methanol poisoning. We present the cranial computerized tomography (CT) imaging findings in acute methanol intoxication in a 44-years-old man who was admitted to the emergency department with weakness, blurred vision and a progressive decrease in the level of consciousness. CT imaging showed bilateral putaminal hemorrhagic lesions. A case is hereby presented in which CT played an important role in making the diagnosis due to poor patient's history and unavailability of methanol assay.

Journal of Neurological Sciences , 2009,
Abstract: Carbon monoxide (CO) poisoning is a rather common in winter months of our country because of stove and flash gas heater. While low doses CO poisoning induce cardiac and neuropsychiatric symptoms; high doses acute or chronic CO poisoning induce coma and death. We evaluated consuquent 10 patients parkinsonism findings who submitted our hospital in the last 6 months. The patients were minimum 22 maximum 60 years-old (Mean 38). Three patients had unilateral and seven patients had bilateral hypokinesia and rigidity. Together with this symptoms; all patients had encephalopathy, psychotic, cardiac or internal symptoms, at different levels. Patients took hyperbaric oxygen, pramipexola and different treatment for their sypmtoms and one of the patients died at the hospital because of cardiac arrest. Other 9 patients symptoms have reduced and their treatment are continuing.

Sociology Mind (SM) , 2014, DOI: 10.4236/sm.2014.43021
Abstract:
This study includes a research on the impacts of core employees on the perceived performances of Small and Medium Sized Enterprises (SME’s). Employees, who are working at manufacturing department or basic function, were taken as core employees in the frame of the research. This research was conducted at the Middle and Eastern Black Sea region of Turkey; at 60 SME’s. The research was realised on the bases of the resource-based view of the firm; the relation between the characteristics of core employees as rareness, hardness to imitation and the perceived performances of SME’s were given. This study contributes to the literature for its regional focus to the topic and for the presentation of how SME’s perceive organizational performance as dimensional context. The results of the research didn’t support the hypothesis which claims that there is a positive relationship between the expertises of core employees, whose superior characteristics are specific to firms and the organizational performance.

Abstract: The aim of this study was to improve pre-service teachers’ ability to infer cross-sections of geometric solids with Wolfram demonstrations and Mathematica in Analytic Geometry II course. The study was conducted with third year students studying Elementary Mathematics Education. In this study, the pre-test--post-test control group design was used. Both before and after the procedure, both groups were administered the Santa Barbara Solids Test (SBST) developed to measure their ability to mentally visualize the cross-section that results from the intersection of a cutting plane and a geometric solid. During the procedure, the participants in the control group were mainly asked to complete the graph drawings of geometric solids by just using plane cross-sections in paper-and-pencil format whereas those in the experimental group were supplemented with computer aided instruction in addition to these paper-and-pencil activities. In addition, the students in the experimental group were asked about their opinions on the procedure. The results showed a statistically significant increase in average achievement for both groups. On the other hand, this increase in the averages was significant for all the indices, and therefore for all problem types, of the experimental group SBST whereas it was significant only for the embedded orthogonal and embedded oblique items and for all problem types of the control group (p<0.05)

Abstract: Abstract Objective:Day Care Centers offer a new alternative to health services for both palliative patients and their care givers (especially working care givers). Patients are takenfrom their homes to these care-giving centers during the daytime, and in the evening theyare returned to their families. In recent years, the importance of day care services hasalso increased with the increasing interest in home care. The purpose of our work; , reveal the perspectives of relatives of patients in the palliative patient care givers towardsthe day care centers Methods:In this descriptive study, a questionnaire with 13 items was applied to thecare givers of the palliative care service patients in U？ak Training and Research Hospital to revieal their point of view towards the day care centers during december 2017 tofebruary 2018. Conclusion:Daytime patient care centers are becoming increasingly widespread inthe world because the care givers are able to continue attending their jobs and spend time with their patients at the same time. In our work, it is clearly seen that, even when thecare givers learn about the day care centers for the first time, they state that they would prefer to use these services
