Current diabetes treatments are based on blood glucose level monitoring. However, it is necessary to design another non-invasive reliable diagnostic method. In current study, we aimed to determine the relation between fasting blood sugar (FBS) and fasting salivary glucose.

In this case-control study, 30 diabetic patients (case) and 30 non diabetic individuals (control) referred to a military hospital in 2019 were studied. The correlation between FBS and fasting salivary glucose was evaluated with Pearson test.

The mean age of participants in control and case group was 55.4±2.8 and 63.7±2 years old, respectively. The mean FBS was 100.5±3.3 and 149.2±3.8 mg/dL in controls and cases, respectively, which were significantly different from each other (p<0.001). The mean fasting salivary glucose in the control group and the case group
was 0.8±0.14 and 1.59±0.35 mg/dL, respectively, which was significant different in the two groups (p=0.038). Pearson analysis showed that there was a positive correlation between FBS and fasting salivary glucose (r=0.265, p=0.042).

Fasting salivary glucose can be used as a noninvasive tool to control blood glucose in diabetics.

Coronary Artery Disease (CAD) is known as one of the leading causes of death in the world. Therefore, in this study, we aimed to investigate the relationship between blood levels of thyroid hormones in euthyroid individuals and the prevalence as well as severity of CAD.

Individuals who underwent coronary angiography were divided into four groups based on their report: 1) normal coronary arteries (NCA); 2) obstruction in one of the arteries; 3) 2‐vessel coronary artery disease (2VD); and 4) 3‐vessel coronary artery disease (3VD). The relationship between CAD and blood levels of thyroid hormones was investigated using the multivariate regression analysis.

In this study, 528 individuals (mean age 54.5±0.7 years) participated; 68% of them were under the age of 65 years. Free triiodothyronine (FT3) serum level was inversely associated with the presence of 2VD in females [OR=0.325; 95%CI:(0.187-0.702)] and in individuals under the age of 65 years [OR=0.401; 95%CI:(0.184-0.601)]. In addaition, there was no significant association between TSH level and 2VD. FT3 was inversely related to 3VD in females and patients under the age of 65 years. Unlike the other groups, the 3VD group had higher serum levels of TSH compared to the NCA group, and therefore the serum TSH level was directly related to of 3VD in patients under the age of 65 years.

Blood levels of thyroid hormone in euthyroid patients are associated with the occurrence of multi-vessel CAD, which indicates that thyroid hormones are only associated with severe CAD.

Colonoscopy and bowel preparation caused a number of serum electrolytes changes that may be dangerous in heart and kidney diseases and elderly patients. To determine the effect of serum electrolytes in patients who underwent colonoscopy and bowel preparation with PEG (Polyethylene Glycol) in Tehran Imam Khomeini hospital in 2008. Fifty nine patients who had been selected for elective colonoscopy after the detection of exclusion criteria were assessed prospectively. Serum level of sodium and potassium were analysed before bowel preparation with PEG (To), before colonoscopy (T1) and immediately after it (T2). Serum calcium and phosphorus levels were measured just before and after PEG. Four patients (6.8%) did not follow the research protocol and were excluded. Four patients (6.8%) developed hyponatremia in T1 that continued in T2. There were no significant differences in prevalence of Hyponatremia and means of sodium serum levels in To, T1 and T2. Although there was a significant trend to decreased means of potassium levels of T2 versus T1 (P
