    Factors exerting recessive effects on susceptibility to complex traits are expected to be over-represented in communities having a higher frequency of consanguineous marriage. Multiple sclerosis, a typical complex trait, is relatively common in Turkey where cultural factors also determine a high rate of consanguineous marriage. Previous genetic studies of multiple sclerosis in Turkey have been confined to the search for associations with candidate genes. In order to exploit the special genetic features of the Turkish population, we performed a whole genome screen for linkage in 43 Turkish multiplex families employing 392 microsatellite markers. Two genomic regions where maximum lod score (MLS) values were suggestive of linkage were identified (chromosomes 13q and 18q23) along with a further 14 regions of potential linkage. Parametric analysis of these data using a recessive model, appropriate for populations with a high frequency of consanguinity, increased the LOD scores in four regions. © 2003 Elsevier B.V.

    Economic impact of primary headaches in Turkey: A university hospital based study: Part II
    (2006) Karli N.; Zarifoǧlu M.; Ertaş M.; Saip S.; Öztürk V.; Biçakçi Ş.; Boz C.; Selçuki D.; Oǧuzhanoǧlu A.; Neyal M.; Siva A.; Irkeç C.; Kaleaǧasi H.; Kansu T.; Sarica Y.; Taşdemir N.; Uzuner N.
    This study was planned to investigate the economic impact of headache on Turkish headache sufferers attending a tertiary care outpatient headache clinic. A total of 937 headache patients were included in this study and questioned using a questionnaire for the profile of patients and headache, quality of life of patients and economic impact of headache. The median total direct cost was found to be 88.0 USD and the median total cost was 160.7 USD. The drug treatment cost was the highest item followed by the specialist outpatient care cost. The average lost and inefficient work/school days was 1.5 (0-45) and 8.4 (0-100) days for one year. It was shown that loss of productivity was higher for migraine without aura group when compared with the episodic and chronic tension-type headache groups. The results of this nationwide university hospital based study showed that headache, especially migraine, has considerable economic impact on patients. © Springer-Verlag Italia 2006.

    Immunolocalization of ERK1/2 and p-AKT in normal endometrium, endometrial hyperplasia, and early and advanced stage endometrioid endometrial adenocancer and their prognostic significance in malignant group
    (Elsevier Ireland Ltd, 2014) Gungorduk K.; Ertas I.E.; Sahbaz A.; Ozvural S.; Sarica Y.; Ozdemir A.; Sayhan S.; Gokcu M.; Yilmaz B.; Sanci M.; Inan S.; Harma M.; Yildirim Y.
    Objective: To analyze the expression patterns of extracellular signal-regulated kinase (ERK1/2) and phosphorylated (p)-AKT in the tissues of non-pathologic endometrium, endometrial hyperplasia, and early and advanced stage endometrioid endometrial adenocancer using indirect immunohistochemistry, and also to investigate the effect of ERK1/2 and p-AKT expression patterns on prognosis in endometrioid adenocancer. Study design: Immunolocalization of ERK1/2 and p-AKT was examined in six different types of endometrial tissues: proliferative endometrium (PE; n = 10, 11.2%), secretuar endometrium (SE; n = 10, 11.2%), simple hyperplasia (SH; n = 15, 16.9%), complex hyperplasia (CH; n = 3, 3.4%) and atypical complex hyperplasia (ACH; n = 10, 11.2%), which were obtained from endometrial biopsies, curettage materials, and hysterectomy specimens and classified as the benign group; and both early stage endometrioid (n = 21, 23.6%) and advanced stage endometrioid adenocancer (AC; n = 20, 22.5%), which were obtained from complete surgical staging materials and classified as the malignant group. All specimens were fixed in 10% formalin and processed using routine paraffin protocols. Immunostaining intensities were evaluated as negative or weak (assigned as low expression) and moderate or strong (assigned as high expression). Results: In the malignant group, 23 of 41 patients (56.1%) had high ERK1/2 and p-AKT expression, whereas only three of 48 patients in the benign group (6.3%) had high ERK1/2 and p-AKT expression (P < 0.0001 and P < 0.0001, respectively). p-AKT expression was significantly higher in women with positive lymph nodes (OR 9.0; 95% CI: 1.2-100.0; P = 0.03). Higher expression of p-AKT was significantly associated with poor progression-free survival (PFS) and overall survival (OS). In contrast, ERK1/2 expression was not associated with PFS or OS.Conclusions ERK1/2 and p-AKT can be useful in the differential diagnosis of benign vs. malignant endometrial lesions, as well as early vs. advanced stage endometrioid endometrial adenocancer. Additionally, higher p-AKT expression could be used as a marker of poor prognosis in the management of patients with endometrioid endometrial adenocancer. © 2014 Elsevier Ireland Ltd.
