Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Multiple myeloma is a plasma cell dyscrasia characterized by proliferation of plasma cells in bone marrow associated with the production of monoclonal immunoglobulins. In recent years, the use of arsenic trioxide, formerly approved for treatment of acute promyelocytic leukemia has been considered for refractory myeloma treatment. This study was designed and carried out to evaluate the efficacy and possible side effects of ATO on patients with refractory multiple myeloma.

Methods: This study carried out on myeloma patients whose diseases were at least refractory to two standard treatment regimens conducted in Ghazi Tabatabaei Hospital in Tabriz- Iran. Arsenic trioxide was administered as an intravenous infusion at a dose of 0.25 mg/kg/d for 5 d/week during the first two consecutive weeks of each 4-week cycle with two week rest. Patients who completed one 4-weak cycle were evaluated for response to treatment.

Results: Twelve patients with refractory disease to conventional treatment regimens received arsenic trioxide. The response to the treatment assessed based on the amount of serum proteins electrophoresis of the 10 patients. Stable disease observed in four patients (33%), progressive disease in five patients (41.6%), complete response in one (3.8%) and the remaning two patients could not be assessed for response (because of increased liver enzymes after the first week). One patient completed six cycles. Some adverse events such as: increase liver enzymes and serum creatinine, neutropenia, pruritus, nausea, vomiting, lower extremities edema, and noninfectious diarrhea were observed.

Conclusions: The use of arsenic trioxide is promising in treatment of refractory multiple myeloma.

Abstract

Background: Nowadays skin damages caused by ultraviolet (U.V.) radiation from the sun were increased accordingly necessity for safe and inexpensive protective products for reducing the harmful effects of this ray is unassailable. The antiradical, anti irritation and anti-cancer properties of silymarin make it a suitable option for use in cream formulation to investigate its effect on skin disorders caused by U.V. radiation. In this research effect of local application of a cream containing silymarin in prevention of the harmful effects of U.V. radiation on the guinea pig skin were studied and evaluated by using histopathologic and clinical findings.

Methods: 75 albino guinea pigs were randomly divided into five groups of fifteens. 2cm2 of the back hair was shaven. In the first group no treatment was applied, in the second group vaseline, in group 3 base cream without silymarin extract, in group 4 silymarin extract and in group 5 cream containing silymarin extract were used.

Results: In clinical assessment, skin scaling, skin irregularity, erythema, skin hyperpigmentation, and edema were observed and in histopathological observation epidermal hyper keratosis, hyperpigmentation, exocytosis, acanthosis, chromatin discoloration in nucleus of epidermal squamous cells, perifolliculitis, dermal vascular hyperemia, edema and dermal thickness, infiltration of plasma cell lymphocytes and eosinophyls into dermis were detected. The statistical comparison of group 1 and group 5 shows statistically significant difference in most indices (p<0.01).

Conclusions: Clinical and histopathologic examinations showed that local application of a cream containing silymarin is effective in prevention of skin damage caused by U.V. radiation in guinea pig's skin also the results of the clinical and histopathologic observation in this study confirm the enzymatic results in other researches.

Volume 75, Issue 6 (September 2017)
Abstract
Background: Urinary tract infections are very common in patients with high blood pressure. Hypertensive patients experience an average of three times of urinary tract infection per year. Blood pressure control is very important for preventing complications and also for identifying high-risk groups. Since, there is no national related study in this regard, the present study was conducted to investigate the effect of chronic hypertension on the incidence and recurrence of urinary tract infections.
Methods: In this case-control study, the required data were collected from outpatient cases referring to Taleghani Hospital and Sina Hospital related to Tabriz University of Medical Sciences in Tabriz city, Iran. Data needed for the control group included patients accompanying patients who had no symptoms of urinary tract infection and with no history of blood pressure.
Results: 60 patients with urinary tract infections were examined: 57 (47.5%) of the subjects were men and 63 (52.5%) women. There was a significant relationship between the rate of red blood cell deposition in the first hour and systolic blood pressure. There was no significant correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients.
Conclusion: According to the results of the present study, there was a significant difference in systolic blood pressure in patients ESR 1 hour (red blood cell deposition rate in the first hour) with hypertension in case and control groups. There was a significant correlation between the ESR of the first hour and systolic blood pressure in the study, so that with an increase in ESR 1h, the systolic blood pressure increased in the examined patients, however, no significant correlation was found between ESR 1hour and diastolic blood pressure. Also, there was no meaningful correlation between the numerical value of white blood cell count and systolic or diastolic blood pressure in the studied patients. There was no significant correlation between systolic and diastolic blood pressure and age.

Volume 75, Issue 8 (November 2017)
Abstract
Background: Studies indicate a prevalence of 39.2% diabetes mellitus (DM) as the most common underlying cause in patients with dialysis. Statistics showed that the rates of morbidity and mortality were higher in hemodialysis patients with diabetes compared with hemodialysis patients without diabetes. The aim of this study was to evaluate the risk factors responsible for infections in patient’s chronic renal failure on hemodialysis patients having diabetic foot ulcers.
Methods: In this cross-sectional study, data were collected from 30 randomly selected hemodialysis patients who were referred to Imam Reza hospital, Tabriz from April 2016 to April 2017. The patients' records were taken according to inclusion and exclusion criteria and data were collected in designed questionnaires for further analysis.
Results: 63.3% of patients were males and 36.7% were females. The average age of study population was 51.23±12.74. Duration of dialysis was 5.15±3.58 years. The average HBA1C was 9.08±1.48. Bacterial cause of feet ulcer was isolated only in 56.7% of cases. Isolated bacteria were anaerobic (47.05%), gram-positive (35.29%) and gram negative (17.64%). Amputation was performed in 26.7% of cases. Mortality was reported in 13.3% of patients. Low personal hygiene, presence of vasculopathy, mortality and amputation was higher in anaerobic infections. Most infections were seen in patients with inadequate dialysis. Low dialysis adequacy, amputation, vasculopathy, increased duration of dialysis, poor hygiene was seen in patients with higher HbA1C.
Conclusion: These results indicate the importance of diabetic foot ulcers caused by anaerobic infections, because of the outcome of amputation and higher mortality rates in these patients, the prognosis is worse than other cases. Also, due to the direct relationship between personal hygiene and the development of anaerobic infections, it is possible to prevent these infections significantly by following these considerations. Most infections were found to be inappropriate in dialysis adequately. Therefore, accurate monitoring of patient's diabetes in the long run and the importance of this can control the complications of diabetes, including vasculopathy, followed by the need for amputation for fighting against diabetic foot ulcers.

Abstract
Background: Ovarian cancer is a leading metastatic disease. The epithelial ovarian cancer is one of the most common malignant cancers that usually remains asymptomatic up to metastasis stages, and most patient when diagnosed are in the advanced stage of the disease. Studies have shown that in the majority of epithelial cancers mesenchymal factor expression such as Vimentin increases, and the epithelial factor expression such as E-cadherin decreases, as a result, it causes an epithelial-mesenchymal transition (EMT). The aim of this study was to determine the expression level of these genes and association between EMT phenomenon and development of ovarian cancer based on clinical and morphological findings.
Methods: In the present case series study, 70 samples were chosen from the tumor Bank of Cancer Institute taken from patients at Imam Khomeini Hospital, Tehran, Iran. The amount of expression of two genes, E-cadherin and vimentin, was investigated by real-time PCR method from February 2016 to September 2017. The RNA extraction was done manually, and then cDNA synthesis was performed; In each sample the expression level of vimentin and E-cadherin was measured with real-time PCR method. The patient’s clinical information with other data were analyzed with nonparametric statistical methods in SPSS software, version 19 (SPSS Inc., Chicago, IL, USA).
Results: There was a significant relationship between expression of vimentin gene and the stage (P=0.026) of the disease and metastasis (P=0.009), There was no significant relationship between vimentin gene expression and tumor grade (P=0.207), age (P=0.11), tumor size (P=0.71) and family history (P=0.6). There was a significant correlation between E-cadherin gene expression and metastasis (P=0.027), no significant correlation was found between E-cadherin gene expression with tumor grade (P=0.690), stage (P=0.753), age (P=0.09), tumor size (P=0.537) and family history (P=0.56).
Conclusion: According to the changes in expression of vimentin and E-cadherin genes in ovarian tumor cells, and association between these two genes with clinical and morphological findings and the role of these genes in the migration and invasion, we can use the both genes, vimentin and E-cadherin, as genes involved in the EMT process to assess disease progression and incidence of cell invasion in ovarian cancer.
