RESUMEN
Neural tube defects (NTD) are among the most common congenital abnormalities, with an incidence of 3 per 1000 live births in Turkey. In a study of major congenital abnormalities in the city of Denizli, Turkey, abnormalities of the central nervous system are particularly common (31.1%). The objective of this study was to develop a registry of cases with NTDs in Denizli. Cases that had been diagnosed with NTD between January 2004 and September 2010 in State Hospitals of Central Denizli were retrospectively examined. The diagnoses were established based on the ICD-10 criteria. A total of 250 subjects with NTD were identified, including 123 (49.2%) females and 127 (50.8%) males with a mean age of 13.72 ± 15.62 years (age range 1-81 years). Interestingly, spina bifida constituted a significant percentage of the cases (149 cases; 59.6%). In addition, 10 (4.0%) cases had hydrocephalus plus spina bifida. The second most common diagnosis was microcephaly, which included 70 cases (28.0%). Encephalocele was observed in only 2 cases (0.8%). Development of NTD is influenced by nutrition, socioeconomic factors, and the use of folic acid during the peri-conceptional period. Studies examining the effect of these factors on NTD in Turkey and a review of primary prevention measures are necessary.

We examined genotoxic damage and frequency of micronuclei in people living in the Bekilli and Suller districts of Denizli city who had been diagnosed with pleural plaques as a result of environmental exposure to asbestos. Peripheral blood samples were obtained from 30 volunteer patients 59-86 years old who did not smoke or consume alcohol and who were diagnosed with calcified pleural plaques. We also examined 30 healthy controls with similar features, who also lived in downtown Denizli. Micronucleus frequencies, nuclear division index, and mitotic index were determined. Micronucleus frequency, nuclear division index, and mitotic index were significantly higher in patients who had been exposed to asbestos than in the controls. We conclude that asbestos had a genotoxic effect, resulting in an increase in micronucleus frequency and other changes in patients diagnosed with pleural plaques secondary to asbestos exposure.

Oral clefts are one of the most common birth defects in humans. However, few population-based studies of these defects have been carried out in Turkey. Our objective was to determine the registries of cases of cleft lip and palate. All cases of cleft lip and palate referred to central state hospitals in Denizli between January 2000 and May 2010 were investigated retrospectively. Anomalies were determined and classified according to the ICD-10 coding system. A total of 194 cases were identified consisting of 92 females (47.4%), 100 males (51.6%), and 2 subjects of undetermined gender (1%) with an age range of 1 to 65 years. Among the 194 cases, 127 subjects (65.5%) had isolated cleft palate, including 63 females and 64 males; 42 (21.6%) subjects had cleft lip, including 17 females and 25 males; and 25 subjects (12.9%) had cleft lip and palate, including 12 females and 13 males. Studies of oral cleft prevalence are insufficient in Turkey owing to the incompleteness of registries, and the chromosome analysis rate has reached a reasonable level only in recent years.

Down syndrome (DS) is the most frequent chromosome abnormality among live births. Its prevalence increases with maternal age, and can be diagnosed by antenatal screening. We examined prevalence variations of DS in Denizli, Turkey, through a retrospective study. Sixteen years of survey data were retrieved from the two main state hospital registries from records between 1994 and 2010. We identified 113 DS live births in Denizli for 16 years. The prevalence of DS was 9.07 per 10,000 live births before the year 2000 and 9.90 after 2000. The prevalence did not change significantly. The population in Turkey is still young; the fertility rate is high in women under 35 years old and prenatal screening programs are extensively applied; for these reasons, the prevalence of DS has remained stable during these 16 years.
