relationship between salivary beta-2 microglobulin and uremia intensity in men with chronic renal failure

This study defines the relationship between salivary beta-2 microglobulin [beta 2-M] and intensity of uremia in male patients diagnosed with chronic renal failure [CRF]. In total of 42 males were enrolled in a case-control study. There were 21 cases of CRF and 21 control cases. We collected 10cc of saliva plus 5 cc of blood from all patients to determine beta 2-M, blood urea nitrogen [BUN] and creatinine [Cr] levels. There was a correlation between the level of serum BUN and salivary urea in controls and patients, which was statistically significant for controls [p=0.028].The correlation between serum and salivary Cr was 0.195 in controls [p=0.398] and 0.598 in patients [p=0.006], which was statistically significant in patients. The correlation between serum and saliva was 0.133 [p=0.566] in controls and 0.078 [p=0.737] in patients, which was not statistically significant. The correlation between serum BUN and beta 2-M was 0.168 [p=0.469] in the control group and 0.629 [p=0.002] in patients, which was statistically significant in patients. The correlation between serum Cr and beta 2-M was 0.110 [p=0.635] in the control group and 0.678 [p=0.001] in patients, which was statistically significant in patients. The correlation between serum BUN and salivary beta 2-M was 0.093 [p=0.0690] in controls and 0.152 [p=0.152] in patients, which was not statistically significant. The correlation between serum Cr and salivary beta 2-M was 0.072 [p=0.070] in the control group and 0.286 [p=0.209] in patients, which was not statistically significant in either group. The results of the study indicated that salivary beta 2-M cannot be used as a non-invasive indicator to detect the severity of renal failure

Simultaneous right coronary artery spasm in a patient with Anterior ST-Segment Elevation Myocardial Infarction: a case report

Simultaneous occlusion of two vessels causing infarction at different territories is an uncommon finding. We report simultaneous right ventricular and anterior ST-segment elevation myocardial infarction in a previously healthy young man. The angiographic results demonstrated the simultaneous occlusion of the right and left coronary arteries because of simultaneous occlusion of left anterior descending artery [LADA] and spasm of right coronary artery [RCA]. In this patient, we found simultaneous ST elevations in right and precordial leads so everyone should be careful about all leads of the surface electrocardiogram for decision making in the management of a patient
