Abstract
Listeria infection is still a dominant infectious problem in Iran, particularly in abortion. Looking for a paraclinical technique other than bacterial methods (which is not always available) lead to serological survey indicating estimation anti listeria antibody by Immunoflourescent test. Unfortunately the false positive results due to cross reaction between "listeria monocytogenesis" and certain gram positive cocci, made it an unacceptable technique. Here we performed a test to extract the Listeria M. (Stranin 4a and 1b) soluble antigen and detecting the antibody by counter immunoelectrophoresis (CEI). The results indicated that of four bacterial soluble antigen fractions F1 and F3 were significantly positive with patients sera. We will discuss using the soluble antigen by CEI technique may be helpful to omit the false positive reactions.

Abstract
Psoriasis is a chronic, inflammatory and proliferative skin disease that has a wide distribution throughout the world. The immune system plays a critical role in developing this disease. In this survey, we have studied 50 patients suffering from Psoriasis and 50 control subjects for various immunological factors, simultaneously. Anti-stratum corneum (SC) antibody was evaluated by immunofluorescent technique that showed a high significant level of it in patients (P<0.005). The titer of immunoglobulins (IgG, M, and A) measured by radial-immunodiffusion (RID) method was also higher in normal population. CIC estimated by PEG precipitating technique demonstrated high concentration in patients. TNF, a cytokine with strong performance to induce inflammation, had no significant rising amount in patient sera, but in synovial fluid in Psoriasis arthritis may have higher levels. We discuss that due to immunological findings we consider that Psoriasis is probably as an autoimmune disorder. The prevention, treatment and prognosis of the disease may follow the same procedures as other autoimmune diseases and further investigation will be helpful to achieve the above goal

Abstract
This cross-sectional descriptive study was undertaken to know the rate of intestinal parasites infestations in our school children population. A sum of 1155 fecal samples were analyzed from an equal number of children whose age were between 6-11 years old. The percentage of infestations were: Giardia lamblia (14.11%), hymenolepis nana (1.21%), ascaris lumbricoides (0.08%) and enterobius vermicularis (0.08%). We found no differences with regard to sex, age, father and mother levels of education, family size, body mass index (BMI) and the erythrocyte sedimentation rate (ER) between the stools positive and the stools negative cases. Nearly all cases of giardiasis (99.4%) were symptomatic. Eosinophilia was seen in (5.5%) of the infested children with giardiasis and in (0.5%) of the non-infested children, the difference was statistically non-significant (P=0.056). All cases of giardiasis (N=163) were treated with metronidazole 15 mg/kg/day in 3 divided doses for 7 days. Metronidazole was effective in (92.2%) of the treated children.

Abstract
Background: All the patients with Angina pectoris have not stenotic coronary artery. Syndrome x consists of patients with Angina pectoris and positive Exercise test along with normal coronary angiography. Syndrome x includes 25-30 percent of those who undergo diagnostic coronary arteriography at the different centers. In our study it was attempted to know the prevalence and characteristics of this special group in Afshar cath-lab.
Materials and Methods: In a prospective cross sectional descriptive study 200 patients who were admitted for coronary angiography evaluated in terms of Risk factors: HTN, Family history Hyperlipidemia, DM, Cigarette smoking , clinical symptoms , response to TNG, different symptoms, ECG and Exercise test. data in two subgroups with normal and abnormal Coronary angioghraphy were compared. Six patients were excluded because of ambiguous Coronary angiography.
Results: Among 194 patients 51 patients (26.3% )had normal coronary artery. 38.9% of female and 21.4% of males showed normal coronary angioghraphy (P = 0.013). The prevalence of risk factors among those with syndrome x and abnormal coronary Artery were as follow. HTN 37% vs 42% , Hyperlipidemia 50% vs 51% , smoking 25% vs 37% , DM 12% vs 28% , obesity 45% vs 47% Positive family history for CAD = 21.5% vs 47% respectively. Angina relieved suitably with TNG in 24% of those with syndrome x compared to 76% suitable response in those with abnormal coronary arteries.(P Value = 0.49 ). Regarding to functional class , 87% of patients with normal coronary artery belonged to class I and II. also 26% had atypical pain 50% had normal rest ECG and 51% achieved stage III or IV of Bruce protocol during Exercise test.
Conclusion: Syndrome x was more prevalent among women ,also angina was less typical and less responsive to TNG. Most patients had not positive familial history for CAD. normal ECG was more prevalent among those with syndrome x .

Abstract
Background: To evaluate the ability of Ankle/Brachial Index (ABI), that is a sensitive and specific test for detection of PAD, to foretell the possibility of ischemic heart diseases in diabetic patients.
Materials and Methods: All of diabetic patients who visited in our diabetes research center between May 2000 and May 2001 and were confirmed diabetics since 2 or more years ago were enrolled in the study. The ABI was calculated for all of the patients and their demographic specifications and ischemic heart disease risk factors were recorded. All of the patients refer to perform an exercise test, but 279 patients were conferred to performing stress test. They were containing: 127 patients with ABI =<1.1(group I) and 47 patients with ABI>=1.4(group III) as case groups and, 105 patients with 1.1 60 years (P = 0.02). 238 patients were in group I (25.1 %), 625 patients in group II (65.9 %) and 85 patients in group III (9 %). 52.8% of 125 patients in Group I, 19.6% of 107 patients in group II, and 44.7% of 47 patients in Group III had positive exercise test. I, II (P 0.00)- II , III (P = 0.05) A total of 108 patients from among the 279 patients had positive exercise test (38%), and most of them were from groups I &III. 72.2% of group I , and 52.5% of group II had high blood pressure (P 0.00). Both hypertensive and normotensive patients with ABI =<1.1 & >=1.4 had positive exercise test significantly more than patients with 1.1=1.4 is an independent predictor of coronary artery diseases in diabetic patients especially in those who are hypertensive.

Background: Atherosclerosis and the side effects thereof
are a major cause of mortality and morbidity in diabetic patients. Diabetic
dyslipidemia is defined by a decrease in blood levels of HDL cholesterol and increases
in triglycerides and LDL
cholesterol. Diabetic dyslipidemia is
atherogenic, inducing cardiovascular disease in diabetic patients at a
frequency that is two to three times greater than that of nondiabetics.
Methods: This study analyzes
the data from the first phase of the Yazd Healthy Heart Program, a community
intervention project focused on the prevention of cardiovascular disease. Using
the cluster sampling method, we analyzed data from 2000 subjects from Yazd, Iran,
ranging in age from 20
to 74 years. Clinical and
paraclinical data were recorded by trained health providers using a
questionnaire with over 700
items.
Results: The most frequent
lipid disturbance was TG>150 in 67.1% of the type-II diabetic patients (p<0.000), 54.6% of whom were unaware
of their TG level. The mean lipid
and TG levels are
significantly higher (p<0.000). Furthermore, women as a group have higher mean cholesterol, LDL-C and HDL-C levels than men (p<0.000). Additionally, diabetic patients were more obese than the
nondiabetic population. (p<0.000).
Conclusion: The high prevalence of
diabetes mellitus in Yazd and hypertriglyceride-mia among diabetics in this
city, in addition to the lack of awareness among more than half of these patients
about their illness and diagnosis, indicate an urgent need to immediately
control dyslipidemia in these high-risk patients.

Abstract
Background: Adequacy of dialysis is a very important issue in dialysis patients, so comparing the adequacy of dialysis in different dialysis methods is very important. Therefore, due to the fact that the number of people undergoing dialysis through fistulas and catheters varies in different centers, and depending on different centers, there is a possibility of decreasing or increasing the adequacy of dialysis, so we decided to do this comparison in Arak support center.
Methods: In this analytical-cross-sectional study, the dialysis patients of Hami Arak Center from April 2019 to September 2019 were divided into two groups (the first group with permanent catheter, the second group with arteriovenous fistula) based on vascular access. The both groups were matched in terms of age, sex, weight, pump speed, filter size and also the duration of dialysis. All patients were dialyzed with the same type of dialysis machine, and the duration of hemodialysis for all samples was 4 hours in each session. To confirm the reliability of the device, it was calibrated before each use and the same setting was used for all samples. The blood samples were taken from the arterial route before dialysis and starting the dilution with heparin or normal saline. Statistical models of dialysis adequacy of patients in two groups were measured using the Kt/V criterion, SPSS and AMOS data analysis was performed.
|
Results: In the analysis of covariance of BUN before dialysis, there is a statistically significant difference in the studied groups (P<0.05), also in the UF and URR variables, dialysis time and the number of times of dialysis in three consecutive repetitions, there is a statistically significant difference in the studied groups. (dime fistula and catheter) are not present (P<0.05).
Conclusion: In this study, during repeated repetitions, 22% of the dialysis adequacy in the two groups did not have good adequacy, and 78% of the patients in the two groups had appropriate dialysis adequacy.

Abstract
Background: Overcrowding in the emergency department is considered as a problem of the public health system, and the present study was conducted with the aim of evaluating the overcrowding in the emergency department of Imam Khomeini Hospital in Urmia based on the EDWIN index.
|
Methods: This descriptive-analytical study was carried out cross-sectionally from March 21, 2019 to March 19, 2020, using a simple random sampling method in patients referred to the emergency department of Imam Khomeini Hospital in Urmia. Which was used to collect information from the demographic information checklist and the EDWIN index was calculated. Then the information was entered into SPSS18 software and analyzed with the help of descriptive and analytical statistics.
Results: In this study, the results showed that in terms of the frequency of triage level, 5.4% was level one, 65.6% was level two, 26.3% was level three, 2.7% was level four and there was no disease in level five. In terms of shift, 22.5% visited the hospital in the morning shift, 27.6% in the evening shift and 49.9% in the night shift. The average EDWIN index was 2.7±0.75 on holidays and 5.9±4.6 on non-holiday days. Although emergency room congestion was more on non-holiday days, this difference was not statistically significant (P=0.15). Also, the average of EDWIN in the morning shift was 2.5±2.3, in the evening shift it was 0.71±2.16 and in the night shift it was 9.7±5.8 and even though the average of EDWIN in the night shift was higher than in the evening and night shifts, this difference was not statistically significant (P=0.06).
Conclusion: The results of the present study indicated that on most of the investigated days, the emergency room was evaluated as crowded based on the EDWIN criteria. Also, there is no significant difference between the busyness of the emergency room according to the holiday or working day, as well as the morning, evening and night shift.
