    OBJECTIVE: The assessment of cognitive impairment after posterior cerebral artery (PCA) ischemic infarction has not been well documanted. MATERIAL and METHODS: Twenty-six oriented, cooperated and non-aphasic consecutive patients with right or left (10/16) PCA infarction who were hospitalized between the years 2010-2012 were enrolled to the study. The branches of PSA were dealt as cortical and subcortical infarct under two groups. Short mental state examination test and cognitive test battery (CTB) created from Wechsler memory scale (WMS), word-catogory association test and similarity test parameters were applied to the patients at the first week and third month follow-up visits and the groups were compared with each other. RESULTS: There was a significant improvement in catogory association test and total score of cognitive test battery (CTB) in right PCA group, also there was a significant improvement in catogory association test in left PCA group at the first and 3th month evaluations. At the first month evaluations, total score of CTB of the subcortical segment PCA infarcts are lower than the cortical segment PCA infarcts. At the 3th month evaluations the scores increased in the both groups; but the scores in the subcortical PCA infarcts were lower than the cortical PCA infarcts. CONCLUSION: Our findings suggest that there was a cognitive impairment in patients with PCA infarction. The impairment in verbal fluency which was showed by catogory association test was found more prominent in the second evaluation. Further studies including functional imaging methods and cortical function tests are needed.

    Relationship between painful diabetic polyneuropathy and hypertriglyceridemia and hypercholesterolemia [Agrili di·yabeti·k poli·nöropati· i·le hi·pertri·gli·seri·demi· ve hi·perkolesterolemi· i·li·şki·si·]
    (2010) Öztürk-Mungan S.; Şahin Ş.; Kiziltan M.
    Introduction: The presence of lipid metabolism disorders in diabetic and painful neuropathies, and the existence of some observations and articles supporting this coexistence states a doubt whether there is a correlation between painful diabetic neuropathy and lipid metabolism disorder. This study was planned to investigate the relation between lipid metabolism and peripheral neuropathy. Materials and Method: Our study included a patient group of 90 who were diagnosed with diabetic neuropathy and a control group of 20 patients without diabetic neuropathy who had mild paresthetic complaints and hyperlipidemia. Patients were evaluated with a detailed history of the illness and neurological examination, total neuropathy score, EMG, fasting blood glucose, HbA1c, total blood cholesterol and triglyceride levels. Results: In 49 out of 90 patients, painful diabetic neuropathy was diagnosed. The groups with and without pain were compared and tested for presence of correlation. Significant associations with fibular nerve response amplitude and cholesterol levels were found (p=0.006) while no correlations with triglyceride levels were observed (p=0.827). The blood lipid levels, especially triglyceride levels, were found to be increased both in painful diabetic neuropathy patients and the ones with positive sensory symptoms. Conclusion: In conclusion, although no statistical significance was found between painful diabetic polyneuropathy and hypertriglyceridemia/hypercholesterolemia, triglyceride levels were found to be increased. This finding warrants further investigation on this subject.
