Relationship between retinopathy and cognitive impairment among hypertensive subjects. A case-control study in the ankara-pursaklar region.

BACKGROUND: The relationship between hypertension and cognitive impairment has been investigated in the literature; several clinical studies suggested a relationship between hypertension and retinopathy. METHODS: We examined the relationship between the retinopathy status and cognitive functions by using the Mini-Mental State Examination (MMSE) among hypertensive subjects older than 40 years who were admitted to our Family Medicine, Internal Medicine and Ophthalmology clinics. The subjects were categorized into three groups: group 1 = control subjects (n = 39), group 2 = hypertensive patients without retinopathy (n = 32), and group 3 = hypertensive patients with retinopathy (n = 25). RESULTS: The number of patients with total MMSE scores less than 24 was distributed as follows: group 1: 3 patients (7.7%), group 2: 4 patients (12.5%), and group 3: 14 patients (56%). Hypertension was found to be related with a significant decrease in total MMSE scores in comparison with group 1 subjects (p < 0.001). Furthermore, retinopathy significantly correlated with lower MMSE scores among hypertensive patients (p = 0.001). Compared with group 1, group 3 showed a significant decrease in orientation (p = 0.001), registration (p = 0.001), attention and calculation (p = 0.004), recall (p = 0.009), and total (p < 0.001) MMSE scores. We also found a significant decrease in recall (p = 0.032) and total (p = 0.034) scores in group 3 when compared with group 2. There was a significant decrease in registration (p = 0.002) and total (p = 0.029) MMSE scores in group 2 when compared with group 1. We also observed negative correlations between duration of the disease and orientation (R = -0.597, n = 32, p = 0.001), and between duration of the disease and total (R = -0.495, n = 32, p = 0.006) scores in group 2. CONCLUSIONS: Hypertension was found to be related with a decline in MMSE scores. This relation was even more significant in the group of hypertensive patients with retinopathy. Thus, we suggest that cognitive tests be routinely used in the follow-up of hypertensive patients.

Clinical importance of gamma glutamyltransferase in the Ankara-Pursaklar region of Turkey.

OBJECTIVE: The aim of this study is to determine the etiologies of serum gamma glutamyltransferase (GGT) elevation and relations between multiple etiologies prevalent in the Pursaklar region of Ankara in Turkey. PATIENTS AND METHODS: The patients referred to the Family Medicine and Internal Medicine departments with various complaints from the Pursaklar region of Ankara between July 2000 and July 2002 were evaluated, and values for GGT, alkaline phosphatase (ALP), and alanine aminotransferase (ALT) levels were determined. GGT elevation was classified as being associated with hepatic, biliary, and other origins. RESULTS: For GGT elevation, hepatobiliary etiologies were more prevalent. The most prevalent hepatic etiology was nonalcoholic steatohepatitis, followed by biliary etiologies. The most prevalent etiology of biliary origin was cholelithiasis. Other etiologies, in order of prevalence, were drug exposure and urinary infection. There were no gender-related differences for distribution of GGT elevation; however, the GGT values for women were higher than those for men.

Is Helicobacter pylori infection a risk factor for migraine? A case-control study.

BACKGROUND: The relation between Helicobacter pylori and Migraine and usefulness of the eradication treatment on headache is controversial. The aim of this study was to determine whether Helicobacter pylori infection is a risk factor for migraine and whether the eradication of the bacterium can reduce frequency, duration and severity of clinical attacks of the disease. METHODS: A total 70 consecutive patients with migraine with aura and without aura who came to Gastroenterology polyclinic with various complaints were enrolled in the study and compared with a group of 60 matched controls. Helicobacter pylori infection was diagnosed by histopathological biopsies, which was taken by endoscopy (Olympus-GIFXQ240 endoscope). The diagnosis and classification of migraine was made according to the International Headache Society (IHS) criteria. We assessed the frequency, duration and severity of clinical attacks of migraine before and after eradication treatment. The eradication control of Helicobacter pylori was made by Helicobacter pylori fecal antigen test by PCR after 2 months. RESULTS: Helicobacter pylori positiveness is more relevant in the migranous patients compared with controls. 84.6% of patients with eradication treatment and 75% of classically treated patients informed to get benefit from the treatment. CONCLUSION: Helicobacter pylori should be examined in migranous patients and eradication of the infection may be helpful for the treatment of the disease.
