Abstract

  Background & Objective : Palpable thyroid nodules are found in almost 5% of the adults. Regarding the high prevalence of this condition, recognizing and evaluating them are important for physicians. Fine Needle Aspiration (FNA) is the first easy and cost-effective way for recognizing pathologic nature of the nods. The present research was an attempt to investigate the epidemiology and evaluate the pathological findings among patients using FNA.

  Methods : This is a descriptive study conducted on all 145(113 female and 32 male) patients referring to the endocrinology clinic of Ardabil in the period between October 1999 to October 2002. The data were collected using a questionnaire, the physical examination of the patients, noting down the clinical finding, doing FNA and its report presented by a pathologist. The data were then analyzed with descriptive statistics and frequency tables using SPSS software.

  Results : Most of the patients (36.5%) were 30-40 years old. FNA of 115 patients (79.4%) was reported as benign and that of 6 patients (4.1%) was malignant, 16 patients (11%) had a doubtful FNA, and in 8 patients (5.5%) the sample was not enough. Among patients with benign FNA, 102 cases (70.6%) had nodular goiter, 8 cases (5.5%) had colloid cyst, 3 cases (2%) had follicular adenoma and 2 cases (1.3%) had thyroiditis. Among patients with malignant FNA 1 case (0.7%) had follicular carcinoma and 5 cases (3.4%) had papillary carcinoma.

  Conclusions : The results indicated that most of the malignant lesion is papillary carcinoma, which has a lower prevalence compared to similar studies. Regarding the higher prevalence of thyroid carcinoma in middle ages it seems necessary to investigate the thyroid nodules in this age- group.

Abstract

 Background & Objectives: Regarding the admitted cases at early infancy in Tabriz Pediatrics Medical Center, this research was carried out to determine the role of Hep.B. vaccination in the incidence of ITP.

 Methods: We studied all patients’ admission files in Tabriz Pediatrics Center from 1993 to 2002. The patients were under 6 months of age and hospitalized with the impression of ITP. There were 25 infants whose ITP was diagnosed upon their clinical findings, blood counts and bone marrow aspiration and confirmed by exclusion of other causes of thrombocytopenia. Hep. B. vaccination has been included in routine immunization in Iran since 1993. In order to compare the incidence rate of ITP before and after 1993, we also sought all ITP patients’ files at the same age group who had been admitted to Tabriz Pediatrics Center during the decade before the beginning of routine Hep.B. vaccination (i.e. 1982 to 1992).

 Results: This study shows a considerable increase in incidence of ITP in infants under 6 months of age between 1993 asnd 2002 compared to the decade before the beginning of Hep.B.vaccination, which is statistically significant (P=0.0029).

 Conclusion: Although there is no facility to measure antibodies in Iran and many other countries, and this is one of the reasons for lack of proof for existence of a relationship between vaccination and ITP incidence, the study of cases in two different periods may strengthen the role of Hep.B. vaccination in the occurrence of ITP at early infancy.

Abstract

  Background & Objectives: Providing, maintainance and promotion of neonatal health as a special high-risk group has a special role in heath services. According to statistics, 4 million out of 130 million neonates, born every year, die in the first week of their life. 99% of this mortality takes place in developing countries. 38% of the deaths below the age of 5 belongs to neonatal deaths. To decrease this mortality, some factors such as mother condition (including health care both before and after pregnancy), perinatal factors and life-threatening factors in the first 28 days after birth. This study was performed in hospitals under Ardabil University of Medical Sciences to determine the related factors of neonatal mortality.

  Methods: This case-control study was conducted on 160 neonatals (80 cases of neonatal deaths and 80 live births as controls). The demographic data of two groups were separately analyzed to obtain descriptive results. Also the most common causes of neonatal mortality were obtained through studying cases. Moreover, the parents of live neonates were asked questions to evaluate the effect of social factors. Finally all of these related factors were compared.

  Results: From 160 neonates under study, 71 (44.4%) were female and others were male. Neonatal mortality in males was 1.3 times as much as that in females. 16(12.1%) mothers had history of still birth. 18(11.3%) mothers were illiterate and 27 (16.9%) had college education. 31(19.4%) neonates were under 1500gr, 42 (26.3%) 1500- 2500gr and others above 2500 gr. 37 (46.3%) mothers in case group and 24(30%) in control had no access to transportation facilities. The most common causes for neonatal mortality were prematurity with 44 (55.1%) cases and aspiration, septicemia, asphyxia each one with 4 (2.5%) cases. There were statistically significant relationship between neonatal mortality rate on the one hand and birth weight, access to transportation facilities and mothers, living place (rural or urban) (p=0.023).

  Conclusion: According to the results, factors such as birth weight, access to transportation facilities as well as the mothers’ living location (rural or urban) were determining factors in the neonatal mortality. Some measures seem necessary to by taken in order to decrease the effect of thses factors.

Abstract

 Background & Objective: Visceral leishmaniasis is a reticulo endothelia system and it is known as 'black fever' by Indians. According to WHO every year there are 500 thousand new cases of it in the world. The province of Ardabil, with 25-40% from all the country's leishmaniasis has a major part in the country and is considered as one of the main focuses in Iran. Due to its importance, this study was done to identify clinical signs and demographic characteristics of the patients.

 Methods: This was a descriptive cross-sectional study which was done retrospectively 110 children who were hospitalized in three different active hospitals between 1375-1382 entered in this study. Disease definition include parasite detection in bone marrow aspivation or special clinical signs (fever, spleenomegal, pansytopenia and weight loss) in addition direct agglutination test was positive. The samples were investigated in terms of demographic information. Place of living, clinical signs and the length of time between the symptoms of the disease and its diagnosis. To get to the results, simple descriptive statistics was used. 37.8% of the patients were diagnosed from the beginning of symptoms with in a month.

 Results: There were 56.4% boys and 43.6% girls of all the 110 children. DAT test was done in 97 patients which was positive in 91 cases (minimum positive titer 1/400). In 42 patients biopsy and bone marrow aspiration was done which was positive in 26 cases (lishman body detection). The age of the patients was 4 months -14 years. The most common findings were fever 97.3% and anorexia 97.1%. There was anemia in 90% thrombocytopenia in 60.8% and leukopenia in 24.8%. There was death in 6 patients (5.5%) and unresponsiveness to the treatment in 3 cases (2.7%).

 Conclusion: The results of the present study nearly corresponds to those of other studies. The main vulnerable community of visceral lieshmaniasis are mainly children. In order to decrease the mortality and morbidity its early diagnosis is essential. It is necessary that the physicians working in endemic regions be familiar enough with the disease.

Abstract

  Background & Objectives: Neonatal mortality rate is a main indicator of hygienic development and recognition of the mortality causes is the first step for reduction of the mortality rate and promotion of this indicator. Therefore, in this study, the causes of neonatal mortality have been investigated in Ardabil medical university related hospitals.

  Methods: This study is a retrospective, cross-sectional and descriptive-analytical one that has been done on the bases of admission's units and filling the medical record form for all neonates who have been admitted to Alavi and Imam Khomeini hospitals in Ardabil from September 2006 to September 2007. The questions of forms consisted of infant’s sex, birth weight, gestational age, cause and age of death. The data were analyzed by SPSS software with utilizing T- test and Chi-Squares.

  Results: During this study, there were 1881 admissions of which there were 148 deaths (7.86%). The causes of mortality were hyaline membrane disease (HMD) (52.02%), sepsis (14.86%), pneumonia (9.45%), congenital anomaly (12.83%), asphyxia (7.43%) and meconium aspiration (3.37%). Among the dead neonates, 54.72% were male and others were female. There were 550 LBW neonates and 111 deaths in this group result of our study showed that mortality rate in LBW neonates was 20.18%. There were 578 preterm neonates and 122 deaths in this group prevalence of mortality rate in preterm neonates was 21.10%.

  Conclusion: Prematurity and low birth weight are the most important and fixed cases of infant mortality. The most common causes of mortality were hyaline membrane disease and sepsis. Therefore, the prevention of preterm labor for reduction of prematurity and its related complication recommended which may lead to decreased rate of neonatal mortality.

Abstract

Background & objectives: Artemisia absinthium (known as wormwood) is used as an antihelminthical, antimalarial, antiseptic and  anti-inflammatory agent, and is used for treatment of gastric pain in the traditional medicine. In the present study, we evaluated the effects of hydroalcoholic extract of A. absinthium on the ovary tissues and pituitary_gonadal axis of the adult female NMRI mice.
Methods: In this experimental study, intraperitoneally (IP) injections of hydroalcoholic extract of A. absinthium, were performed over 30 days on 50 mice with 50 (first group), 100 (second group), and 150 mg/kg.bw (third group) doses.  The sham group was received distilled water and control group received no injection. After 30 days of injections, the animals were dissected, and blood samples were collected by heart aspiration.  The levels of LH, FSH, estrogen and progesterone of serum were measured by ELISA method. Seven µm sections of ovary were prepared by a microtome and stained by H&E method. Data were analyzed by One-Way ANOVA and Tukey post- hoc test. The Significance level was set at p<0.05.       
Results: Our findings indicated a significant reduction (p<0.05) in the body weight in all experimental groups compared with sham and control groups. In parameters such as: large and small diameters of the ovary , number of primary, secondary, growing, graafian follicles, and corpus luteum, a significant decrease was observed in 100 and 150 mg/kg doses (p<0.05). In all experimental groups, no significant changes were observed in estradiol and progesterone levels. However, FSH and LH showed a significant decrease in 100 and 150 mg/kg doses (p<0.05).
Conclusion: Therefore, it can be concluded that Artemisia absinthium hydroalcohlic extract in high doses has damaging effects on the process of oogenesis, which may be due to α and β Thujoun, Alkaloid and Saponin constituents in this plant.
