Non-insulin dependent diabetes mellitus is often associated with some complications such as nephropathy, retinopathy and neuropathy. Genes of the renin angiotensin system are potential candidate genes for diabetic complications. We investigated the relationship between angiotensin converting enzyme (ACE) gene polymorphism in type 2 diabetic patients with and without diabetic nephropathy. Seventy five patients (25 type 2 diabetic patients with nephropathy, 50 type 2 diabetic patients without nephropathy) and 37 healthy controls were studied. Gene polymorphism of ACE was determined by PCR (polymerase chain reaction) amplification using allele-spesific primers. The frequencies of ACE DD, ID and II genoypes among the patients with type 2 diabetic patients were found 48%, 42%, 10% whereas in control subjects, 27%, 60%, 13% respectively. Type 2 diabetic patients carrying DD genotype without nephropathy increased 1.77 fold than control subjects (P < 0.05). There is no significant correlation between diabetic nephropathy and ACE gene polymorphism. But we found that ACE DD genotype increased significantly in type 2 diabetic patients compared to control subjects (P < 0.05).

This survey was designed to investigate the socio-demographic characteristics of and utilization of a Primary Heath Care Unit (PHCU) by Roma people (Turkish Gypsies), who live in the coverage area of Muradiye Primary Health Care Unit, as compared to members of the general population. This was a cross-sectional field study involving members of the Muradiye PHCU district. The study population comprised 127 Turkish gypsies resident in the region and 302 households selected by a stratified random sampling method. 889 household members were interviewed face-to-face at their home by means of a structured questionnaire. When the two sample groups were compared in terms of their social security coverage, rates of unemployment and educational levels, the situation of the Turkish Gypsies was found to be worse than that of the other members of the general population. 63% of the Gypsies applied to the PHCU because of health problems and 87% of these cases were treated successfully. Among those people making use of the PHCU services 47% evaluated them as being "satisfactory". Access to the PHCU services was found to be conditioned by educational level, being a Gypsy, the possession or not of a Green Card (available only to highly indigent people), whether or not the services were provided free of charge and the possession or not of social security coverage. Muradiye PHCU is well known and highly appreciated in its coverage area and is used by almost all of the residents. The main reason for the significant discrepancies in the level of health care obtained by the two population groups is the Gypsies' poorer economic situation. Among the Gypsies, the leading category of low rate social security coverage is the Green Card, which is granted to the very poor in order to reduce these inequalities. Unfortunately, the Green Card does not provide financial support for ambulatory care.

The X-ray repair cross-complementing group 1 (XRCC1) gene is believed to play an important role in base excision repair and displays genetic polymorphisms. Data on the role of XRCC1 polymorphisms in cancer susceptibility is inconsistent. In the present study, we investigated the effect of two XRCC1 polymorphisms, Arg194Trp and Arg399Gln, on breast cancer risk in a case- control study involving Turkish breast cancer patients and healthy women. Both alleles exhibited a similar distribution among cases and controls leading to lack of any significant association between the XRCC1 polymorphisms and breast cancer risk, either in homozygotes and heterozygotes or combined. The allele frequency of the codon 194 variant was very low in cases and healthy individuals (5.3 and 3.9%, respectively) compared to that of the variant 399Gln allele (39.7 and 37.4%). Our results do not support evidence for a role of the XRCC1 polymorphism in developing breast cancer.
