Pages 1-9Background And AimsWe investigated the children of Parana State, Brazil the prevalence of intestinal parasitosis and the associated factors involved in the transmission of intestinal parasites, and we genotyped the Giardia duodenalis isolates obtained.MethodsFecal samples were analyzed by established microscopic methods.
G. duodenalis positive samples were subjected to genotypic characterization by PCR amplification of sequences of the glutamate dehydrogenase gene (gdh) and by enzymatic digestion with the restriction enzyme NlaIV for classification of genotypes.ResultsOf the 877 samples tested, 41% were positive for some intestinal parasitosis, the most common being the presence of protozoa (87.8%). Lack of basic sanitation and poor health education were associated for the intestinal parasite cases found, and the only associated factor for giardiasis was low family income. The G. duodenalis assemblages of gdh amplified samples were 68.6% B and 31.4% AII.ConclusionThese data demonstrate the importance of epidemiological studies for the development of effective strategies with the aim of decreasing the incidence of intestinal parasites in children. Moreover, these results contribute to our knowledge of G. duodenalis assemblages circulating in the world and also offer support for future work on the molecular and clinical aspects of giardiasis.Keywords: Giardiasis, Intestinal parasitosis, Epidemiology -
Pages 10-17Background And AimsThe frequency of chronic hepatitis B virus infection varies totally in different part of the world but it could be categorized as high, intermediate and low endimicity. In this regard, development of safe and effective vaccines against infectious diseases especially hepatitis B virus that are still required for emerging new pathogens, re-emerging old pathogens and in order to improve the inadequate protection conferred by existing vaccines. In this study, immunological studies were conducted pertaining to investigate the aqueous leaves extract of Calotropis gigantea and Ficus religiosa for determining its adjuvant effect against hepatitis B vaccine containing surface antigen (HBsAg).MethodsIn this study, our group evaluated the secondary metabolites that are present in the aqueous extract using high performance thin layer chromatography (HPTLC) and estimated its antibody (IgG) titre against HBsAg using variable doses (2.5-10 mg) of aqueous leaves extract of these medicinal plants and also determined splenocyte proliferation assay (ex vivo studies) on day 4 where mice (n=5) were immunized subcutaneously on day 0 with HBsAg (20 µg/ml, 100 µl).ResultsThe results showed that aqueous leaves extract showed anti-HBsAg titre and also enhanced splenocyte proliferation assay at higher doses (10 mg, 50 µl) as compared to control.ConclusionOverall, the results showed that aqueous leaves extract of Calotropis gigantea and Ficus religiosa showed adjuvant activity against HBsAg.Keywords: Calotropis gigantean_Ficus religiosa_Hepatitis B vaccine_Adjuvant

Pages 44-52Background And AimsRecent studies on mortality in Iran, in recent years clearly emphasize that unintentional injuries are the main cause of reducing Iranian life expectancy in Iran. This article aimed to assess the role of major causes of death for mortality patterns in the country by sex in 2010.MethodsExperimental results of this study are based on death registration system of Ministry of Health (MOH). Using multiple decrement and single decrement life tables, years of life which could be savedare calculated if unintentional accidents were to be eliminated from causes of death. Then the composition of age groups is decomposed.ResultsThe results showed that unintentional injuries are cause of reduction of 2.3 years of Iranian mens life and 0.8 years for women. More detailed results show that mortality from unintentional accidents in active age groups (15-64 years old), have a great role in reducing the life expectancy of the people. The mens share is more than 70%, but for women the share of age groups of 15-65 years old is less than men, in return, it is more for women under 15 years old is more.ConclusionSince high rate of deaths due to unintentional accidents are preventable, control and intervention, especially among young people, and society development needs to improve the health of the main age groups, mean young, so investments to increase productivity and improve the health of young people is necessary.Keywords: Life expectancy at birth, Unintentional accidents, Multiple decrement life tables, Decomposition

Orlando's nursing process application on anxiety levels of patients undergoing endoscopy examinationPages 53-60Background And AimsAnxiety is a common reaction when people encounter new problems where they do not know what expect. The nurses are responsible for assessing the patient and helping them with the procedure of endoscopy. This study investigates differences in anxiety level of patients who receive nursing process of Orlando's theory prior to endoscopy examination compared to a control group.MethodsA Quasi -experimental research design was used in this study. Samples were 60 adult patients who were randomly assigned to two groups (30 patients each). Patients in the study group receive nursing process of Orlando's theory by the researcher plus the routine hospital intervention, while the control group only received the routine hospital intervention. The Spielberger State-Trait Anxiety Inventory (STAI scale) is administering to both groups before and after endoscopy examination. STAI, a self-reporting psychometric test, is used to assess state anxiety levels. STAI has demonstrated reliability and validity in previous studies.ResultsStatistically significant difference was evident between the 2 groups regarding the mean of anxiety level of patients after the intervention. Before the intervention, the mean of anxiety level in the control and study groups were 47±9 and 58 ±11 and after the intervention were: 41±7, 35±7, respectively.ConclusionIntervention groups have the lower mean of anxiety level after the intervention. Female patients in this study experienced low level anxiety compared to male patients after Orlando nursing process. The data suggest that endoscopy unit personnel and the referring physician should consider the patients perception of the procedure. Detailed information on the procedure and training in relaxation techniques should be given. Positive re-appraisal and information on sensations to be anticipated, rather than procedural details, will be more successful in alleviating stress and anxiety.Keywords: Orlando's theory, Anxiety levels, Endoscopy examination

Pages 61-68Background And AimsAmong all cancers, colon cancer is common and deadly, yet preventable. The estimated worldwide incidence of colon cancer is more than one million new cases per year. This study was done to identify the epidemiological features and risk factors of colon cancer in different regions of Birjand.MethodsThis retrospective, descriptive analytical study of patients with colon cancer was conducted in Birjand educational hospitals. This study examined the patients whose colon cancers had been confirmed by a pathologist (2006-11). Statistics related to these patients were collected from pathology centers affiliated to Birjand University of Medical Sciences. Data were analyzed using descriptive (frequency and relative frequency) and analytical (chi square test) statistics. SPSS software was used to analyze the collected data.ResultsResults of the present research showed that a total of 38 people with colon cancer were hospitalized in Birjand educational hospitals between 2006 and 2011. In the present study, there was a significant difference between the patients job and the type of morphology (P=0.018) and the therapeutic procedures (P=0.001); Adenocarcinoma was mainly reported among housewives (n=10, 76.9%). Concerning therapeutic procedures, housewives underwent colectomy surgery more than other groups (n=8, 61.5%).ConclusionControlling colon cancer which is one of the most common cancers in the world is a great epidemiologic success. The findings of this study presented a complete and exact image of epidemiology of this cancer in the region and provided the authorities with precious information; therefore, they can make decisions about identifying colon cancer risk factors in the region.Keywords: Colon cancer, Cancer epidemiology, Prevalence

Pages 69-77Background And AimsQuality of visit services is a decisive aspect of patient-physician communication that its inadequacy can negatively influence the diagnosis efficiency. The aim of this study was to survey visit quality at provincial level during plan of health sector evolution in Tabriz.MethodsA sample of 540 patients who referred to the outpatient clinics (Sheikh Al Raeis of Tabriz Province) in North West of Iran was randomly selected. Data were collected by a researcher-made checklist and summarized using descriptive statistical methods.ResultsThe average visit time was found to be 8.52 minutes, which is significantly lower than the minimum average of 15 minutes approved by the Iranian Ministry of Health and Medical Education (MOHME). The average of waiting time was found to be 101.57 minutes for patients. The results showed that the structural quality was found to be 51.36%, process quality was found to be 62.69% and outcome quality was found to be 50.82%.ConclusionVisit length was shorter than other developed and developing countries. If the consultation process in health care delivery to patients is incorrect or incomplete, the following process will be without quality and security. This study showed that visit time is short and waiting time is very long.Keywords: Visit quality, Health sector evolution, Physician- patient relationship, Outpatients

Pages 78-83Background And AimsCharcot Marie Tooth disease (CMT) is the most prevalent hereditary neuropathy and its frequency is 1 in 2500. CMT is a heterogeneous disease and has different clinical symptoms. The prevalence of CMT and involved genes differ in different countries. CMT patients experience considerable sleep problems and a higher risk of decreased quality of life. In this work it was aimed to provide a review on the genetic and epidemiologic aspects of this disease.MethodsIn the current review article, we performed a literature search on the epidemiology of CharcotMarieTooth disease and provided a brief review on epidemiology, genetic, and complications of CMT. Databases Web of Science and PubMed were searched using the Endnote software for the publications on CMT during 2000 to 2016.ResultsCharcot Marie Tooth disease has different prevalence around the world and is the most common neuropathy. Epidemiological studies have estimated the prevalence of CMT in Japan 1/9200, in Iceland 1/8300, in Spain 1/3500 and in Italy 1/5700.The patients have different phenotype and the age of onset. There is a variety of inherited patterns of disease and many genes have been identified responsible whose mutations are main cause of the disease.ConclusionDue to the impact of this kind of disabilities on the national health, further studies seem to be necessary to gain better knowledge of the disease particularly in the regions with higher prevalence. Moreover molecular biology services offered by genetic laboratories can reduce the incidence of disorder.Keywords: Charcot Marie Tooth, Neuropathy, Electrophysiology, Epidemiology

Pages 84-90Background And AimsImmunosuppressive regimens are a key component for successful kidney transplantation. This systematic review aimed to assess the efficacy and safety of combination therapy of everolimus with tacrolimus in kidney transplantation recipients.MethodsResults were limited to English-language articles. Trials where recipients received another regimen were excluded. The Cochrane Central Register of Controlled Trials and MEDLINE were searched via the optimally sensitive strategies for the identification of randomized trials, combined with the following MeSH headings and text words: Everolimus, Certican, Zortress, tacrolimus, prograf, and kidney transplantation.ResultsFive relevant studies of everolimus in combination with tacrolimus were identified and results of them were interpreted. Two trials investigated Fix dose of everolimus in combination with low (1.5-3 mg) versus standard dose of tacrolimus (4-7 mg). One trial investigated variable doses of everolimus (1.5 mg/day or 3 mg/day) in combination with fix dose of tacrolimusand two trials compared fix dose of everolimus versus reduction or elimination of tacrolimus. Sample size of RCTs ranged from 20 to 398 and the follow up time ranged from six to 24 months. The quality score on the Jadad score was 3 in all five trials indicating moderate quality.ConclusionImmune suppressive regimens including everolimus in combination with tacrolimus therapy show better safety and efficacy compared with single-mode but these differences were not significant in overall studies. In general, compared with a regimen without combination of everolimus with tacrolimus, the newer immunosuppressive regimen consistently reduced the incidence of short-term biopsy-proven acute rejection. However, evidence about impact on side-effects, long term graft loss, compliance and overall health-related quality of life is limited.Keywords: Everolimus, Tacrolimus, Kidney transplantation
