A morphological study of uterine alterations in mice due to exposure to cadmium.

We investigated the morphologic and molecular effects of exposure to cadmium (Cd) for 30 and 60 days on the uteri of mice. We assessed uterine morphometric measurements, eosinophilia, mast cell numbers, endometrial apoptosis, proliferation and estrogen receptor alpha (ERα) immunoreactivity. We examined vaginal smears that reflected the hormonal alterations in the female reproductive tract. Because the female reproductive tract exhibits different morphology at each stage of the estrous cycle, we sacrificed all animals at estrus to make appropriate comparisons. Female BALB/c mice were exposed to 200 ppm Cd in their drinking water for either 30 or 60 days. Cd exposure caused significant decreases in endometrial thickness and number of glands in estrus phase uteri. The endometrial eosinophilia in the groups exposed to Cd also decreased compared to controls. Cd exposure increased the number of mast cells. Luminal and glandular epithelia were examined using the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay and by immunostaining proliferating cell nuclear antigen (PCNA) and estrogen receptor α (ERα). Compared to controls, the apoptotic index increased with time in both Cd exposed groups, while the proliferation index decreased. ERα immunoreactivity was decreased in both Cd exposed groups compared to controls; the decrease was most apparent in the 30 day Cd group. We found that 60 day Cd exposure increased apoptosis in the endometrium, which may affect the receptivity of the uterus for implantation.

Impacts of maternal anxiety on non-stress test parameters.

OBJECTIVE: To determine the association between antenatal maternal anxiety with non-stress test (NST) parameters, which is an indi- cator test of fetal well-being in the third trimester. MATERIALS AND METHODS: Between January and December of 2013, 212 pregnant women, with 36-41 weeks of gestation were assessed with measures of distress and anxiety with Beck Anxiety Inventory (BAI) and with NST. The new National Institute Child Health and Human Development (NICHD) 2008 guideline criteria were used for interpretation of NST. Anxiety scores were grouped as minimal, mild, moderate, and severe. The impact of anxiety on NST parameters were investigated. RESULT: Anxiety scores were inversely correlated with fetal heart rate (FHR) accelerations (r = -0.631, and r = -0.855), number of fetal movements (r = -0.633, r = -0.860), FHR variability scores (r = -0.650, r = -0.877). and NST scores (r = -0.505, r = 0.729), (for all p < 0.001). NST scores were lower in severe anxiety group than the others. CONCLUSION: The study showed that severe form of anxiety significantly affects NST parameters in near-term pregnancies.

Efficacy of low-dose intratympanic dexamethasone for sudden hearing loss.

OBJECTIVE: Intratympanic steroids (ITSs) are recommended for treatment of sudden sensorineural hearing loss (SSNHL). On the other hand, the dosage, frequency and duration of the intratympanic therapy are still not clear. We aimed to evaluate the efficacy of low-dose intratympanic steroid (ITS) treatment of SSNHL. METHODS: Seventy patients (ears) treated for SSNHL were involved in the study. The patients were divided into four groups: the systemic steroid, combined, intratympanic initial (ITSi) and intratympanic salvage (ITSs). The demographic data, accompanying symptoms, treatment onset duration, the treatment protocol, and pre- and post-treatment pure tone audiometry results were recorded. RESULTS: The mean treatment onset was 60 days in the ITSs group, which is statistically later than the other groups (p<0.001). The treatment response was assessed based on Siegel's criteria. Hearing recovery was statistically higher in the combined group than the systemic steroid group (p=0.042). 87.5% of the ITSi group showed full recovery, which is a statistically significantly higher difference than the other groups (p<0.001). In the salvage treatment group, the use of low-dose ITS was observed to be inadequate for the treatment (p<0.001). The post-treatment pure tone average gains in dB were analyzed at 500, 1000, 2000, and 4000Hz and the recovery determined for each of the four groups was found to be statistically significant (p<0.001 to p<0.031). CONCLUSION: The ITS administration as the initial treatment for mild to moderate hearing loss is adequate while low dose of dexamethasone used as a salvage treatment is inadequate. The use of low-dose ITS in the combined treatment may increase the hearing gain.

Epicardial adipose tissue in patients with subclinical hypothyroidism.

AIM: There remains conflicting opinions regarding the relationship between the risk of cardiovascular disease and subclinical hypothyroidism (SH), and there are also varying study results. Recent growing evidence suggests that epicardial adipose tissue (EAT) may play a key role in the pathogenesis and development of coronary artery disease. The effects of SH on echocardiographic EAT is not currently known. The aim of this present study was to measure echocardiographic EAT with anthropometric and clinical parameters in patients with SH. METHODS: The study was designed as a prospective and case-controlled study. Body fat ratio, echocardiographic EAT measurements, body mass index, and the waist circumference of patients were measured for analysis. RESULTS: Epicardial adipose tissue was measured to be 3.83±1.04 mm for patients with SH, while it was measured to be 2.81±0.74 mm in the control group, and there was a significant difference detected between two groups (P<0.001). CONCLUSION: In the present study significantly increased EAT in patients with SH was detected.
