RESUMEN
Background: oxidative stress is one of important risk factors of deiseases specially in military recruits who are under sever practices Vitamin C is one of the major antioxidant factors which also help to increase iron absorption. Vitamin C and probably iron deficiency due to that, can decrease soldier forces and cause various diseases particularly pulmonary diseases. The purpose of this study is to determine serum level of vitamin C and iron and TIBC in military recruits to prevent following problems due to deficiency of Vitamin C
Materials and Methods: This study was done as a cross-sectional study in September 2007 in Tehran and 51 soldiers were chosen randomly who were between 17 and 24 year sold. 5 cc blood was collected for determining serum vitamin C, iron and TIBC. Prevalence of vitamin C and iron deficiency and relationship between vitamin C and iron serum levels and between vitamin C and iron serum levels and between vitamin C and TIBC serum levels were calculated
Results: Mean value of serum level of vitamin C 0.57 +/- 0.23 SD was less than normal range. [0.6-2 mg/dl], and prevalence of vitamin C deficiency among the soldiers of this study was 56.8%. However, mean value of serum iron 102.57 +/- 53.78 mg/dl SD was in normal range [60-180 mg0dl] and also TIBC amounts 364.51 +/- 59.00 mg/dl SD was in normal range [230-410 mg/dl]. Relationship between vitamin C and TIBC serum levels was reversely significant [P<0.001]
Conclusions: It is advisable to get more attention to provide more vitamin C resources for young soldiers for preventing to iron deficiency status or other potent dangers
RESUMEN
Background: there are several systemic disorders which have adverse effects on periodontal tissue, such as diabetes. Previous studies of non-diabetic patients have demonstrated higher levels of fasting blood sugar [FBS] among those with periodontitis compared to those without periodontitis. In an attempt to clarify whether periodontal diseases incline the patients to a pre-diabetic state or not, we studied the FBS level of non-diabetics with periodontitis and compared the results with those who had no periodontal involvement
Materials and methods: eighty non-diabetics who referred to the outpatient clinics of dentistry faculty, Azad University, Tehran, during 2003 were evaluated in this case control study. 40 patients with periodontitis constituted the cases, and 40 without any periodontal disease made up the control group. Plaque index, bleeding on probing [BOP], probing pocket depth and clinical attachment loss were measured and recorded. FBS was determined for both groups and its levels higher than 126 indicated diabetes, while levels between 110 and 126 were considered as pre-diabetic state. Both descriptive and analytic analyses were applied. P-value of less than 0.05 was considered statistically significant
Results: spearman correlation test results indicate a direct relation between FBS and BOP in the control group [r = 0.382, p = 0.015]
Conclusions: our results are in agreement with previous studies in demonstrating the increase in blood glucose levels associated with periodontal tissue inflammation in the chronic periodontitis patients
RESUMEN
Background: laryngeal tumors are uncommon and account for 2% of all human malignancies. Timely diagnosis of these lesions improves patients' outcomes. The incidence of laryngeal carcinoma has been increasing within recent years, mostly due to increased tobacco and alcohol usage. Accordingly, we studied the epidemiologic characteristics of different types of laryngeal tumors
Materials and methods: this was a retrospective, noncomparative case-series. All pathologic report sheets regarding laryngeal diseases in Imam Khomeini Hospital, Tabriz, obtained from patients between 1377 and 1380 were retrospectively reviewed. Tumor type, age and sex were recorded and analyzed using descriptive methods
Results: seventy neoplastic lesions were observed: 44 malignancies [41 cases of squamus cell carcinoma], and one malignant melanoma, papillary carcinoma and adenocarcinoma], 24 benign tumors [21 polyps and three papillomas] and two preneoplastc lesions [one carcinoma in-situ and one medium-grade dysplasia]. Sixty-six patients were males [89%] and the average age was 58 years. The majority of patients were in their seventh decade of life at the time of the disease
Conclusion: our statistics are generally similar to those observed in other countries, including senile and gender-related distribution of the disease as well as relative frequency of different tumor types. Further analytic studies with larger patient population seem to be mandatory to elucidate the effect of epidemiologic risk factors on the occurrence of laryngeal tumors
