Tenascin C levels in patients with mild and severe preeclampsia

Objective: To determine the serum tenascin-C (TN-C) levels in cases with mild and severe preeclampsia.

Methods: Pregnant women were divided into three groups, namely healthy pregnants (Group 1, n?=?20), pregnants with mild preeclampsia (Group 2, n?=?20) and pregnants with severe preeclampsia (Group 3, n?=?20). The groups were formed so as to match each other in terms of gestational week. From each pregnant woman, pre- and post-delivery blood samples were obtained to measure serum TN-C levels. The data were evaluated using the Kruskall–Wallis variance analysis. For the obtained values of p?<?0.05, the groups were compared in pairs. A p value of <?0.017 was accepted as significant.

Results: In Groups 1, 2 and 3, the prepartum TN-C levels were 5.02?±?0.4?µg/ml, 12.8?±?2.9?µg/ml and 33.8?±?11.7?µg/ml, and in the postpartum TN-C levels were 4.7?±?0.1?µg/ml, 11.7?±?1.8?µg/ml and 50.6?±?33.8?µg/ml, respectively. There was a significant difference between the groups in terms of the prepartum and postpartum TN-C levels (p?<?0.017, Mann–Whitney U [MWU] test). There was also a significant difference in the prepartum TN-C levels between Groups 2 and 3 (p?<?0.017, MWU test).

Conclusions: The prepartum and postpartum TN-C levels were significantly higher in mild and severe preeclampsia than those in healthy pregnants.     

Vitamin D insufficiency in a boy with obsessive–compulsive disorder

Vitamin D deficiency not only causes low bone mass but also may lead to neuropsychiatric disorders. In the present case, vitamin D supplementation reduced obsessive–compulsive disorder (OCD) symptoms associated with streptococcal infection in a 7‐year‐old boy. Sudden onset of symptoms, including excessive hand washing and fear of touching anything, had occurred 1 month before presentation. Although there are few studies on a possible causal relationship between vitamin D and neuropsychiatric disorders, the present report; together with previous data, suggest an etiological role of vitamin D‐related immune processes.     

Influence of serous retinal detachment on the outcome of ranibizumab treatment in diabetic macular oedema

Purpose: The purpose of this study was to evaluate the influence of serous retinal detachment (SRD) on the outcome of intravitreal ranibizumab (IVR) therapy in diabetic macular oedema (DME).

Materials and methods: Fifty-one eyes with cystoid macular oedema (CME) and SRD (study group) and 57 eyes with only CME (control group) that received pro re nata (PRN) IVR injections during a 6-month period were retrospectively evaluated. The outcome measures included changes in the central macular thickness (CMT) and best corrected visual acuity (BCVA) and injection numbers.

Results: The mean initial CMT in the study and control groups was 467?±?101 and 440?±?89?µm, respectively. The mean BCVA in the study and control groups was 0.75?±?0.38 and 0.59?±?0.36 logarithm of minimal angle of resolution (LogMAR), respectively (p?=?0.010). The study group received a mean of 2.2?±?0.92 injections, whereas the control group received a mean of 2.54?±?0.9 injections. The decrease in CMT was greater, but not significantly greater, in the study group than in the control group.

Conclusion: The presence of SRD resulted in a less favourable visual acuity (VA) outcome with IVR. Disruption of the ellipsoid zone and abnormality of the foveal avascular zone at the baseline examination were correlated with a lower VA. Both of the pathologies occurred more frequently in the SRD group.     

Do health care reforms in Turkey have a significant effect in equal access to maternal and child health services in Turkey: An evidence from 20 years

This study aimed to investigate whether there was an improvement in the equitable access to maternal and child health care services by examining the effects of socioeconomic and individual factors in Turkey from 1993 to 2013 and determine the effectiveness of health care reforms implemented mainly under the Health Transformation Program since 2003 on equitable access t;o maternal and child health care services in terms of years. The study used nationally representative 5 Turkey Demographic and Health Surveys (1993, 1998, 2003, 2008, and 2013). Prenatal care utilization rate increased from 67.0% in 1993 to 96.2% in 2013 while the rate of women giving birth at health care facilities increased from 63.8% to 98.1% in 2013. Prenatal care utilization and giving birth at health care facilities were higher among women who were under health insurance coverage, first time mothers, those staying in the western region and urban areas, and those with the highest level of wealth. The findings suggest that the issue of equity in the utilization of maternal and child health care services exists in Turkey, and the latest health care reforms under HTP are not effective in diminishing the effect of wealth.     

The effect of desensitizing treatments on the bond strength of resin composite to dentin mediated by a self-etching primer

This study evaluated the bond strength of resin composite to dentin, mediated by a self-etching adhesive, following the application of various dentin desensitizing treatments and artificial saliva storage. The buccal cervical areas of 24 extracted human third molars were ground flat to expose cervical dentin. The dentin surfaces were polished with 1200-grit SiC paper, then the teeth were randomly assigned to six groups, five desensitizing treatments and one control: Group I-VivaSens; Group II-Fluor Protector; Group III-Isodan; Group IV-Futura Bond NR; Group V-Nd:YAG laser and Group VI-Control (without application of a desensitizing agent). After applying the desensitizing treatments and storing the molars in artificial saliva for 14 days at 37 degrees C, Futura Bond NR was used to bond resin composite to dentin. TPH composite build-ups were constructed incrementally to a height of 5 mm. The teeth were sectioned to obtain bonded slices of 0.7 mm thick specimens containing the resin-composite joint. The specimens were then trimmed into an hourglass shape and subsequently subjected to microtensile testing at a crosshead speed of 1 mm/minute. The data were analyzed using the Kruskal-Wallis analysis and multiple comparisons test. The control (Group VI) and Futura Bond NR self-etching treatment (Group IV) group yielded statistically significant higher bond strength values than the other desensitizing treatment groups tested (p < 0.005). While pretreatment of dentin surfaces with desensitizing agents (Fluor Protector, VivaSens and Isodan) and laser (Nd:YAG) reduced the bond strength values of the resin composite, higher bond strengths were achieved using a self-etching adhesive (Futura Bond NR) as a desensitizing agent.     

Relationship between left ventricle geometric patterns and lymphocyte DNA damage in patients with untreated essential hypertension

OBJECTIVE: To investigate the association between different the left ventricle (LV) geometric patterns and lymphocyte DNA damage in patients with hypertension (HT). METHODS: We studied 84 patients (50.0+/-6.1, years) with HT and 24 healthy control subjects (48.6+/-3.3, years). Four different geometric patterns were identified in patients according to LV mass index and relative wall thickness. Peripheral lymphocyte DNA damages and plasma levels of total antioxidant status (TAS) were determined in all subjects. RESULTS: DNA damage was increased in hypertensive patients compared with control group (p=0.001). The major increase in DNA damage was observed in concentric hypertrophic geometric pattern compared with all other geometric patterns (p<0.001, for all). In multiple linear regression analysis, lymphocyte DNA damage was independently correlated with only TAS (beta=-0.444, p<0.001), but not LV geometry (p>0.05). CONCLUSION: The major increase in lymphocyte DNA damage was observed in concentric hypertrophic geometric pattern. This result may be related to increased oxidative stress.
