We might suggest that the elevated levels of TGF-beta2 in the aqueous of glaucoma patients could play a role in the pathogenesis of glaucoma.

The findings suggest that IL-6 and IL-8 may be involved in the pathogenesis of PDR, PVR, and traumatic PVR. High proportions of RPE cells and macrophages are associated with elevated IL-6 and IL-8 levels in the vitreous of PDR and PVR patients; however, the fact that these cells are not predominant in traumatic PVR suggests that different immune response mechanisms may be active in the pathogenesis of these disorders.

Fibromyalgia syndrome (FS) is characterized by widespread pain and tenderness at specific anatomic sites. Different theories have been proposed in the etiopathogenesis of this syndrome, and besides genetic, neuroendocrine, psychologic, and traumatic causes, infections have also been reported. The aim of the present study was to evaluate the presence of FS in patients with hepatitis C virus (HCV) infection. Ninety-five patients with chronic HCV infection and 95 healthy controls were enrolled in the study. The 1990 American College of Rheumatology classification criteria were used for the diagnosis of FS. Tender point count, pain intensity, sleep disturbance, stiffness, headache, paresthesia, fatigue, irritable bowel syndrome (IBS), and sicca- and Raynaud-like symptoms were assessed. Fibromyalgia was found in 18.9% of patients and 5.3% of healthy controls. Mean tender point count, pain intensity scored on a visual analog scale (VAS), sleep disturbance, stiffness, paresthesia, and fatigue were higher in the HCV group. No significant relationship was observed between the two groups regarding headache, IBS, and sicca- and Raynaud-like symptoms. In addition, mean tender point count and pain intensity scores were also significantly higher in HCV patients with FS than in control subjects with FS. All of the symptoms except stiffness were not statistically significant between the HCV and control groups with FS. Our results demonstrate a tendency toward higher prevalence of FS in patients with HCV infection. Besides various extrahepatic features, musculoskeletal disorders including fibromyalgia might be expected in the progression of HCV infection. Detailed examination of the patients helps to differentiate FS from other musculoskeletal complications of HCV infection. This will provide appropriate management approaches and better quality of life for them.

The study results suggest that elevated plasma homocysteine level may play a role in the pathogenesis of venous thrombosis in BD.

Introductionβ-Thalassemia and hemoglobinopathies are common genetic disorders in Turkey and in this retrospective study our aim was to determine the frequency of β-thalassemia and hemoglobinopathies in Adana, which is one of the biggest cities located in the southern part of Turkey.Material and methodsData from 3000 individuals admitted to Seyhan Hereditary Blood Disorders Center in Adana were evaluated. The blood samples were collected into EDTA-containing tubes and hematological parameters were analyzed using an automatic cell counter. High performance liquid chromatography technique was used to determine the type of hemoglobin. Molecular screening of the β-globin gene was performed with β-Globin StripAssay.ResultsOf 3000 cases, 609 were diagnosed as β-thalassemia or hemoglobinopathy. We have found that the rates of occurrence of β-thalassemia and hemoglobinopathies are 13.46% and 6.83% respectively in this area. We have identified 18 different β-thalassemia mutations and three separate abnormal hemoglobins: HbS, HbD Los Angeles, and HbE. In molecular analyses, β-thalassemia gene mutations of IVSI.110 (G > A), codon 8 (–AA), IVSI.1 (G > A), IVSI.6 (T > C), –30 (T > A), IVSII.1 (G > A), codon 39 (C > T), codon 44 (–C), IVSI.5 (G > C), codon 5 (–CT), codon 8/9 (+G), IVSII.745 (C > G), codon 22 (7bp del), –101(C > T), codon 36/37 (–T), IVSI.15 (T > G), codon 6 (–A), –88 (G > A) were detected.ConclusionsConsidering the high incidence of mutations that we have found, β-thalassemia and hemoglobinopathies still seem to be a public health problem in Adana.
