Abstract: 

روش ارایه شده برای درمان تحلیل لثه در بیش تر موارد برای پوشش ریشه در دندان های بدون سایش است. در بررسی پیشین ریشه های دچار سایش شدید از مطالعه خارج می شدند یا تقعر حفره مانند (wedge-shaped defect) با کاربرد فرز یا توسط کورت، کاهش داده می شد تا به عنوان عامل مداخله کننده در پوشش ریشه تاثیر گذار نباشد. در این مقاله درمان تحلیل لثه در دندان دارای سایش شدید یک بیمار گزارش شده است. در این روش جراحی از فلپ جابه جا شونده تاجی همراه با پیوند بافت همبند برای درمان تحلیل لثه کلاس یک میلر همراه با سایش شدید دندان های پرمولر راست فک بالا در مردی 57 ساله استفاده شد. در این مورد، بر خلاف بیش تر مطالعه های قبلی، زوایای تیز قسمت سایش یافته صاف نشد و بعد از 3 ماه، حدود 86 درصد پوشش ریشه به دست آمد. این گزارش پیشنهاد می کند مطالعه هایی با زمان طولانی تر و در صورت امکان با طرح split mout clinical trial بر روی ریشه های دارای سایش شدید  انجام می شود تا در صورت حفظ دراز مدت نتایج درمان، این روش به عنوان یکی از روش های درمانی دندان های دارای سایش شدید معرفی شود.

Abstract: 

Background: Mercury is a heavy metal and transition element in periodic table that has many uses in industries, agriculture and medicine. This element can enter the body through different routs including food materials, ventilation and skin. Objective: To investigate the short and long term effect of mercury on thyroid hormone in the sera from rats. Methods: Mercuric chloride in doses of 3 mg/kg (short term or 10-day injection) and 1 mg/kg (long term or 45- and 60-day injection) was injected intraperitoneally into three test groups of rats (n=5). Following each period of injections, the blood samples were collected for T3, T4, TSH and T3 uptake measurements. Blood cholesterol level was measured simultaneously for monitoring cholesterol changes. Findings: After the 10-day injection, values for T3, T4 and TSH in test group were decreased 29, 18 and 30 percent, respectively, compared to control group (P<0.04). T3 uptake was increased 23 percent (P<0.04). The 45-day injection caused a decrease in the levels of T3, T4, and TSH as 30, 16 and 40 percent, respectively. T3 uptake and blood cholesterol levels were increased 25 and 8 percent respectively. Following the 60-day injection, the levels of T3, T4, and TSH in test group were decreased 51, 28 and 44 percent, respectively. T3 uptake and blood cholesterol levels were increased 22 and 11 percent respectively (P<0.05). Conclusion: Based on data obtained from current study, it seems that mercury chloride can lead to hypothyroidism and causes an increase in blood cholesterol level. Direct toxic effect of mercury on liver leads to low protein synthesis and may contribute to increase the serum concentration of T3 uptake. Higher level of cholesterol may be attributable to resulting hypothyroidism, which in turn lowers T4 and T3 concentrations.

Abstract: 

Background: Noise is one of the major physical pollutants in present societies. Sound conditioning is used as means of protecting against noise-induced hearing loss. The status of plasma antioxidant system during sound conditioning is important. Objective: To study possible involvement of plasma total antioxidant ability in noise-induced hearing loss and sound conditioning. Methods: This study was carried out on 24 male white New Zealand rabbits (6 in each group). The rabbits were assigned to the following four groups: (1) Noise exposure (250Hz-20000Hz, 110 dB for 8h/day for 12 days), (2) Conditioning noise exposure (80dB for 10 days and 110 dB for 12 days), (3) Noise exposure (80 dB) and (4) control group. Auditory Brain stem Response (ABR) was measured and compared in all pre- and post-exposures groups. Plasma antioxidant power was also measured post exposure. FRAP was assayed in plasma sample collected from each animal using TPTZ reagent. Findings: The ABR assay using click in different experimental groups showed that the absolute latency of 5th wave generation was statistically significant in first group as compared to other groups (p=0.0001).  Likewise ABR assay using tone burst showed a higher absolute latency observed in group 1. FRAP assay indicated that the antioxidant parameters were suppressed in group 1 when compared with data obtained from other groups (p<0.05). Conclusion: The ABR results found in our study, confirmed sound conditioning in rabbits exposed to 80 and 110 dB. Furthermore, changes in FRAP in rabbits studied in our experiment was indicative of involvement of antioxidant system in sound conditioning however, further studies needed.

Abstract: 

Background: Satureja Khuzestanica is an endemic plant of Iran widely distributed in the southern part of the country. This plant is famous for its medical applications as an analgesic and antiseptic in folk medicine.Objective: To investigate the effect of oral administration of aqueous extract of Satureja Khuzestanica on hemostasis and body weight in vivo.Methods: This research was an experimental study carried out in Lorestan Medicinal Herbs Research Center, Lorestan University of Medical Sciences, Khoram-abad, Iran. Thirty six rats were randomly divided into 3 groups. An equivalent of 50 mg of aqueous extract of Satureja Khuzestanica/kg was orally administered. For two weeks the rats in group 1 and 2 received an equal amount of extract once and three times a day, respectively.  Control group received only pure water. Animals' weights were measured every day. Following two weeks, prothrombin time (PT), activated partial thromboplastin time (APTT) were determined. Data were analyzed using One-way analysis of variance (ANOVA) followed by the Tukey multiple comparison tests.Findings: As compared to control, the administration of aqueous extract of Satureja Khuzestanica as 3 separate dose/day resulted in a significant prolongation of APTT by 20.7% (p<0.001), PT by 15.7% (p<0.05) and a reduction of body weight by % 9.24 (p<0.001) after 2 weeks.Conclusion: Regarding our data, it seems that the aqueous extract of Satureja Khuzestanica induced some changes in coagulation activity shown by increased values for APTT and PT. Loss of body weight in rats was also observed when the extract administered three times a day.

Abstract: 

Background: Hyperalgesia is one of the major symptoms of diabetic neuropathy in some patients and could affect life quality. Regarding treatment of hyperalgesia, there are some evidence for antidiabetic potential of tarragon in traditional medicine. Objective: To evaluate the analgesic effect of oral administration of tarragon in streptozotocin-induced diabetic male rats. Methods: This was an experimental study in which 40 rats were randomly divided into control, tarragon-treated control, salicylate-treated control, diabetic, and tarragon-treated diabetic groups. All treatment periods continued for one month. At the end of the experiment, nociceptive response was evaluated in both acute and chronic phases of the standard formalin test. Findings: The results showed that there was an increase in the pain scores in both phases of the test and in diabetic rats (P<0.05), and administration of tarragon for one month did produce a significant reduction in nociceptive scores for both phases, especially in the chronic phase of the formalin test (P<0.05). In contrast, sodium salicylate as positive control only reduced pain scores in the chronic phase (P<0.05). Conclusion: Oral administration of tarragon for one month has a significant analgesic effect in diabetic rats and this may be considered as a potential treatment for diabetic neuropathy.

Abstract: 

Background: Synthetic drugs, although very effective, have their own side effects. Recently, herbal plants have received more attention to avoid the unpleasant effects of synthetic agents. Objective: To investigate the effects of garlic aqueous extract on contraction power of isolated atrium from male rats following administration of adrenalin.  Methods: Male rats (Spirague Dawley, Albino, 200-250 gr) were divided into 7 groups as follows:  Control, adrenalin, garlic extract (10 mg/kg, 20 mg/kg, and 40mg/kg), Propranolol and Propranolol plus garlic extract at a single concentration of 40 mg/kg. Later the contraction power was recorded using a physiograph set. Findings: Garlic extract at all three concentrations used in our study caused a reduction of atrial contraction power in adrenalin group. When the degree of contraction power reduction was compared between garlic extract (40mg/kg) and garlic extract plus Propranolol groups, no statistically significant difference found. Conclusion: Atrial contraction power decreased in presence of garlic aqueous extract and the degree of reduction was significant in both low and high doses, statistically.

Abstract: 

Background: Easiness, accuracy, reliability and usefulness of fine needle aspiration biopsy (FNAB) have been frequently verified. This procedure is routinely used to diagnose the tumors of thyroid and parotid glands in head and neck areas. Objective: To investigate the diagnostic value of FNAB in central giant cell granuloma (CGCG) of the jaws. Methods: 16 cases out of the patients referred to surgery department of dental faculty were chosen based on radiolucent lesion in which a CGCG as a differential diagnosis was suspected. In each case the perforation and aspiration of lesion was performed using an 18 gauge syringe. Sampling was carried out in triplicate e.g., three syringes and three different points. The aspirated samples were smeared on slides, fixed with Patofix and sent to pathology department to be examined histologically. Findings: In four samples from a total of 16 specimens obtained by FNAB, the pathology report was indicative of the presence of giant cells as well as bleeding, inflammation, lymphocytes and polymorphonuclear cells. Histopathological studies on postoperative specimens confirmed the presence of CGCG in three samples out of four. The results showed a sensitivity of 100% and a specificity of 75% for giant cell granuloma of the jaws using FNAB method. Conclusion: Based on data found in our study, the application of FNAB technique, if performed precisely, in combination with clinical and radiographic findings will effectively help in diagnosis of CGCG. This will cause a reduction in expenses, size of stress and physical damage to patients and also prevent seeding of lesion.

Abstract: 

Background: Regression is one of the complications, which may occur following LASIK eye surgery in high myopic patients. Objective: To determine the degree of regression after LASIK in high myopic eyes. Methods: This interventional longitudinal study was performed on 34 eyes in 20 patients who underwent LASIK. The range of preoperative refraction errors was -6.12 to -22.00 Diopter. LASIK was performed using Moria microkeratome to create a 9 mm diameter, 160 microns thick flap. Preoperative and four consecutive cycloplegic refractions were carried out using recommended standards. The maximum follow up was after 6 months. Findings: Considering all patients, mean preoperative refraction was –10.58 D which decreased to -0.51±1.33 D a week following surgery. Mean cycloplegic refraction was –0.98±1.33 D,  -1.21±1.81 D and -1.42±1.87 D, respectively, which was recorded at 1,3 and 6 months postoperatively. Maximum regression occurred 6 months after the surgery [0.9±0.8 D (8.5%)]. Factors associated with regression included preoperative keratometry (P=0.013) and correction rate (P<0.001). Conclusion: The degree of regression after LASIK in high myopia was related to preoperative keratometry and correction rate.

Abstract: 

Background: BCG vaccine is a safe and effective product. The most common side effects are ulceration at the site of vaccination and also regional lymphadenitis. The risk of suppurative lymphadenitis is more common in neonates than in infants and children. Objective: To detect the prevalence of BCG adenitis in vaccinated infants and also evaluating the correlation between incidence of BCG adenitis and sex, birth weight and gestational age of neonates. Methods: This was a retrospective analytical study in which 500 infants vaccinated at birth were evaluated for presence of BCG adenitis using a questionnaire. The correlation between occurrence of BCG adenitis and sex, gestational age and birth weight of neonates was analyzed by chi-square test. Findings: The prevalence of BCG adenitis was 6%. No positive correlation between occurrence of BCG adenitis and the neonate sex was found. However, there was a positive correlation between occurrence of BCG adenitis and both the neonate birth weight and gestational age (p<0.05). Conclusion: Based on data found in our study, more attention to gestational age and birth weight is recommended to reduce the occurrence of BCG vaccine complications.

Abstract: 

Background: Smoking is one of the major health problems worldwide and health politicians, especially medical doctors can play a key role in preventing and controlling of this global epidemic among their patients. Objective: To evaluate the physicians' knowledge, attitude and practice (KAP) towards smoking. Methods: This was a descriptive analytical study in which the target population included all general physicians employed in state-run or private sectors. A total of 5140 GPs in 20 provinces of the country were randomly chosen based on available information from health care organization. Data were collected using questionnaires completed by educated questioners. Findings: The prevalence of smoking among general physicians was 7.43% (9.7% in males and 0.8% in females). Regular smoking was found in 1.79% of women and 10.37% of men and the average of cigarettes used by smokers was 6.6 per day. The average age to start smoking was 23.04±5.7 years. Most doctors (90%) believed in necessity of education to quit smoking manners. Conclusion: Although the prevalence of smoking among GPs found to be less than the general population, regarding the important of their roles, inclusion of extra educational sessions on tobacco control and prevention methods in universities seems to be of prime necessity. This will eventually cause a decrease in prevalence of smoking among this important shell of the society.

Abstract: 

Background: Hyperemesis gravidarum is one of the pregnancy complications which leads to decreased efficiency of pregnant women. Objective: To examine a hypothesis indicative of the presence of an association between hyperemesis gravidarum (HG) and Helicobacter pylori (HP) infection. Methods: This work was a case control study carried out on 35 pregnant women with HG (study group) and 35 asymptomatic pregnant women (control group) admitted to Kosar hospital, Qazvin, Iran in a six-month period between 2003-2004. Serum specific IgG for HP was assayed on the sera of both studies a control groups after formal agreement was made. Data were analysed statistically using Chi-square and student t tests. Findings: Serologically positive HP infection was detected in 23 out of 35 patients with HG (%65.7) whereas in control group, only 7 out of 35 asymptomatic gravidas (%20) were found to have positive antibody titers against HP. The ratio of HP positivity in pregnant women with HG was significantly higher than asymtomatic group (P<0.004). The mean index percentages of IgG titers in study and control groups were 27± 30  and 10 ±13, respectively. Conclusion: HP infection seemed to be significantly associated with HG in pregnant population with hyperemesis gravidarum investigated in our study.

Background: Diagnosis and treatment of neonatal hypothyroidism is of prime importance.Objective: The aim of this study was to compare thyroid hormones levels before and after exchange transfusion in neonates with indirect hyperbilirubinemia admitted to Quds children hospital, Qazvin, Iran.Methods: This study was performed on 20 neonates with indirect hyperbilirubinemia chosen as candidates for exchange transfusion. The neonates were full term and over 37 gestational weeks. Thyroid hormones levels of neonates and blood bags were measured using ELISA method. In neonates, the thyroid hormones concentrations were measured at 3 different times: before, immediately after, and also 3 days after exchange transfusion. The results were analysed by t test.Findings: The data showed that the mean concentrations of T4 and TSH in neonates' blood were higher than in blood bags (P<0.05). There was a decrease in T4 and TSH values in samples taken immediately after exchange transfusion, although returned to values before exchange after 3 days. There was no statistically significant difference between mean concentrations of T4 and TSH in neonates' blood collected in the periods before and 3 days after exchange transfusion.Conclusion: The data found in our study showed that there was a return to normal values of T4 and TSH  in neonates 3 days after exchange transfusion. Thus the screening of neonates for hypothyroidism could be performed at this time.

Abstract: 

Background: Diagnosis and treatment of asthma is of particular importance. Objective: To determine the prevalence of asthma among Qazvin school age children. Methods: This was a descriptive cross sectional study carried out in April 2003. The study was performed using (ISAAC) first phase questionnaires using a selected method for 5936 subjects. The data were analyzed using chi-square test. Findings: Out of a total of 5936 questionnaires sent to the same numbers of selected children only 5068 responses (2518 primary and 2550 secondary) were received. The prevalence of self reported asthma was 2 % and 2.02 % in these two groups, respectively. The prevalence of the life long wheezing history (asthma symptom) was 10% in the primary school children and 26 % in the high school students. Conclusion: Asthma has a moderate prevalence in Qazvin. The regional asthma detection rate is low and this leads to difficulties in accurate treatment of disease. More education recommended for both the members of the public and the clinicians.

Abstract: 

Background: There is little information regarding the food consumption pattern and nutrient intake in pregnant women, especially those residing in deprived cities. Objective: to determine the food consumption pattern and nutrient intake in pregnant women with further comparison of data in rural and urban areas of Maku-the west north of Iran. Methods: In this cross-sectional study 284 pregnant women (142 from urban areas and 142 from rural areas) were chosen randomly and privately interviewed using a face-to-face technique. Socio-demographic information such as age, educational level, family size, husband’s occupation and pregnancy medical history were obtained by questionnaire. The data on dietary intake was collected using two 24-hour recalls and a food frequency questionnaire for 3 months. Findings: Mean consumption of grains and dairies was higher in rural women compared to those in urban areas. Fruit consumption by pregnant women in urban and rural areas was 140 g and 248 g, respectively. There was no significant difference regarding consumption of vegetables, pulses, fats and oils between two groups. All women consumed adequate amount of energy, protein, thiamin and niacin (>75% RDA). Nutrients intakes including folate, B6, A, D vitamins, iron, phosphorus, calcium, magnesium and zinc were found to be insufficient in both groups (<75%RDA). Conclusion: Our data indicated that the rural women had a better nutritional status than urban women. Further studies are needed to determine factors associated with food consumption pattern in these women.

Abstract: 

Background: Acute myocardial infarction (MI) with inflammatory response is a result of tissue necrosis due to leukocytosis and increased number of peripheral blood neutrophils. Objective: To investigate the relationship between neutrophils and congestive heart failure (CHF). Methods: This cohort study was performed on 100 patients affected by acute MI who had two points out of three standard criteria (physical examination, enzyme and EKG findings) during the last 6 months of 2002 in Yahyanezhad hospital, Babol, Iran. CHF was detected through physical examinations, medical history, chest X-ray, and echocardiography using a CFG 750 VinG Med Instrument at the fourth day of admission. Ejection fraction ≤ 40% was considered as heart failure. The data included parameters such as ejection fraction, age, sex, location of infarction, time of admission, use of trombolytics accompanied with laboratory reports on leukocyte count, neutrophil and lymphocyte percentage at the first day of admission which were further analyzed using SPSS, Fisher's exact examination, Univariate, and Loglinear statistical tools. Findings: Out of 54 cases with neutrophilia greater than 65% (p=0.003), 25 patients were found to have developed heart failure at 4th day. There was a significant correlation between both neutrophilia and heart failure with sex (p<0.05). No significant correlation was found (p>0.05) when the age of patients taken into account. Conclusion: Our data show that the neutrophilia of admission time correlates significantly with heart failure as an early onset of acute MI.  This could be useful both in detection of high-risk people and also diagnostic and therapeutic measures.

Abstract: 

Background: One of the prophylactic methods in avoiding postoperative nausea and vomiting (PONV) is the application of intraoperative supplemental oxygen which was shown to have a protective effect in some studies yet a matter of controversy among different researchers. Objective: To study the effect of postoperative oxygen therapy on PONV. Methods: This quasi-experimental study was performed on 106 eligible patients subjected to elective cesarean section in 2003. The patients were randomly assigned into two groups. Anesthesia and drugs in intraoperative and postoperative periods were the same in two groups. In intraoperative period all patients inhaled 50% oxygen balanced with N2O. One group received 60% oxygen in postoperative period (study group), and a second group received routine care of 30-40 percent oxygen in recovery room and no oxygen on surgical ward (control group).  SPO2 and PONV were recorded in recovery and surgical ward. Findings: PONV was 28.3% and 24.5% in study and control groups, respectively. There was no significant difference between two groups. Conclusion: Our study suggests that postoperative application of 60% oxygen was of no value to produce preventive effect on PONV in patients undergoing cesarean section.

Abstract: 

Background: During recent years, the cost of hospital services is increased in most countries and in spite of greater volume of resources devoted to hospitals, the ineffective management of hospitals has led to wasting of resources, hence, the measurement of hospitals efficiency or comparing between the input and output in such organizations is of special importance. Objective: Comparing between two methods, Ratio analysis and Multiple-Attribute Decision Making model (MADM) to estimate the hospital efficiency. Methods: This was a descriptive analytical study carried out in 1998. The efficiency of 5 general hospitals affiliated to social security organization in Tehran province was compared using two methods named as “Ratio” and “MADM”. Findings: The results of this study showed that all hospital under investigation were facing problem with proper use of their inputs (beds) from a scale efficiency point of view.  Regarding the technical efficiency, 3 out of 5 hospitals were involved in shortage of personnel. Conclusion: Our data shows that, the Ratio method, due to some limitations in simultaneous use of quality and quantitative criteria, is incapable to measure hospital efficiency and providing a final conclusion by which the establishment of a ranking system to compare hospital efficiency could be made.
