Volume 56, Issue 5 (6 1998)
Abstract
In this paper, factors affecting the result of prophylactic lymph node dissection in 125 patients with skin melanoma during the period between 1987-1992 in the cancer institute were evaluated and prognostic parameters ascertained. The result showed prevalence of head and neck melanoma in men were two times more than in women with a preponderance of regional and lymphatic recurrence. Majority of patients presented with advanced clark levels (76.8 Pct). Clinical and histologic evaluation of the regional lymph nodes failed to show any meaningful relation.

Abstract

Background: Hyperhomocysteinemia is an independent risk factor for cardiovascular diseases. The frequency of hyperhomocysteinemia is higher in hemodialysis (HD) patients than the general population. The objective of this study is to assess the efficacy of high-dose folic acid supplementation with and without vitamin B12 on lowering plasma total homocysteine (tHcy) concentrations in HD patients.

Methods: Thirty-six HD patients at Imam Hossein Hospital, Tehran, Iran, who had been given folic acid supplements (5 mg/d) for at least 3 months before, were enrolled in this clinical trial. Subjects were also checked for other inclusion and exclusion criteria. The subjects were divided randomly into four groups and underwent two months of supplementation as follows: 5 mg/d oral folic acid + placebo in group one, 5 mg/d oral folic acid + vitamin B12 (1 mg/d orally) in group two, 15 mg/d oral folic acid + placebo in group three and 15 mg/d oral folic acid + vitamin B12 (1 mg/d orally) in group four. Concentrations of plasma tHcy and serum folic acid and vitamin B12 were measured at baseline and after the supplementation period. Dietary intake of patients was also determined during the supplementation period.

Results: Of the folic acid supplemented patients, 27.8% had normal levels of tHcy at baseline and 72.2% had hyperhomocysteinemia. After the supplementation period, plasma tHcy increased by 1.35% in group one and decreased by 6.99%, 14.54% and 30.09% in groups two, three and four respectively. Changes in plasma tHcy and serum vitamin B12 were only significant in group four however, no significant changes were seen for serum folic acid. The percentage of subjects reaching normal levels of plasma tHcy was 5.6 fold higher in group four than in the reference group.

Conclusions: Supplementation with 15 mg/d folic acid together with 1 mg/d oral vitamin B12 is more effective in reducing tHcy levels in HD patients.

Abstract
Background: Age is a strong risk factor for increasing the risk of severity and death from Covid-19. The risk of hospitalization for Covid-19 disease increases with age. Since the elderly constitute a large proportion of Covid-19 patients, the present study was performed to evaluate the severity of the disease in the hospitalized elderly due to Covid-19 and the delay in hospitalization and death resulting from it, for better disease management.
Methods: The present retrospective cohort study was performed on 444 elderly patients with Covid-19 admitted from 1 April until late October 2020 in Baharloo Hospital in Tehran, Iran. After being diagnosed using the results of RT-PCR and CT scan, patients, were divided into 3 groups: moderate, severe and very severe based on the severity of the disease. Analysis of variance was used to compare quantitative data and a chi-square test was used to examine qualitative variables in disease groups.
Results: From 444 elderly participants in the study, 73% were infected moderately, 15% severely, and 12% had a very severe form. The mean age was 72.90±8.42 and patients with a very severe form of the disease (75.68±8.28) were older. The average time from the onset of symptoms to hospitalization was 7 days. In the elderly with a very severe form of the disease, respiratory dyspnea (P=0.002) and decreased level of consciousness (P<0.0001) were higher. The average hospital stay was 7 days. In very severe form it lasted up to 11 days. ICU mortality and hospitalization were higher in patients with very severe forms of the disease. With the increasing delay in the days of hospitalization, the severity of the disease and mortality has increased.
Conclusion: The study showed that prolonging the onset of symptoms till hospitalization worsens prognosis and also exacerbates the disease and increases mortality in the elderly.
