[ long term effects of occupational electromagnetic fields exposure on peripheral blood indexes in workers of aluminum processing factory of Arak]

The effect of electromagnetic fields on human health and especially the risk of carcinogenesis have been comprehensively studied. However, the vast majority of findings of these studies were controversial. Therefore, the aim of this study was to determine the effects of electromagnetic fields on the hematological determinants in individuals who exposed to these fields during long-term period. This was a prospective study carried out in an aluminum processing factory in Arak, Iran. First, the magnetic strength of the field was measured about 25-32 mTesla. Subsequently, 200 workers from the exposed group [case] and 200 workers from non-exposed group [control] were chosen from the same factory with age and sex match. Both groups were examined and followed up using physical exam, data gathering sheet and CBC during two consecutive years. Using SPSS, the data were analyzed and P values less than 0.05 were considered statistically significant. There was no difference between mean age or sex of the two groups studied. Means of hematological determinants in the exposed group were more than those of the non-exposed group in the cases of neutrophiles, red blood cells [RBC], haemoglobine and hematocrite during two consecutive years. Also, the means of monocytes, RBC, Hb and HCT were statistically different between the two groups during this period [p<0.05]. However, no case of malignancy, anemia, polycytemia or coagulopathy was detected in the two groups. Although there was statistically significant difference between the two groups, all the blood indices were in the normal range in both groups and no pathological abnormality was detected in their hemalopoietic system. Conclusively, to determine the hematological disorders in exposed workers, more comprehensive studies during long-term period may be required

[ study of acute renal failure incidence in patientsadmitted to emergency surgical ward of Vali-e-Asr hospital, Arak]

Acute renal failure [ARF] is one of the relatively incident complications in surgical emergency wards and is defined as increasing serum urea and creatinine and decreasing GFR. In this study we investigated acute renal failure incidence in patients admitted to emergency surgical ward. This is a cross sectional analytical study in which j all patients with primary diagnosis of emergency surgery [traumatic or nontraumatic] admitted in emergency surgery ward were selected. After history taking and physical assessment patients having history of kidney diseases were excluded. Urinalysis, BUN and creatinine tests were performed for all samples. Data was analyzed by SPSS software. In this study 2100 patients [1280 male] were assessed during a 10 month period. 5.66% of samples had some degree of ARF. 1136 patients undergone surgery due to accidents and trauma [72% multiple trauma and 28% single trauma] and 964 patients due to nontraumatic emergencies. ARF was seen in 6.84% of the first and 4.25% of the second group. ARF incidence in male and female was 5.6% and 5.7% respectively. The overall incidence of ARF in this study was not so different / fromdevelopedcountries.ARFwassignificantlymoreincidentintraumatic
