ABSTRACT: This paper reflects upon the challenges while implementing information and communication technologies (ICT) in the pedagogical organization of literature teachers, in particular those of language and literature PhD students. Furthermore, we seek to reflect upon teacher’s training, mainly concerning children’s literature teaching. By taking such aspects into consideration, it has been proposed the support of two post-graduate students going through an oriented teaching experience (Docência Orientada) in a Children’s Literature course, in the context of the Federal University of Santa Maria (UFSM) pedagogy undergraduate degree, while using ICT for literature teaching and learning. In this context, it has been checked whether the resources they used helped achieve their goals and whether they aroused student’s interest in the content, thus fostering learning. From the analysis of the reports, it became clear that learning how to apply and use ICT in the classroom is important.

ABSTRACT: This paper aims at investigating experiences from students (postgraduate teaching apprentices) with activities developed through the WebQuest tool in order to observe traces of autonomy by the postgraduate students. This research also sought to scrutinize possible changes in students' perceptions regarding their role as a language teacher. The theoretical approach that guided this investigation encompassed the notions of autonomy, both from the learner’s and the teacher´s perspectives (BENSON, 1997; 2008; DICKINSON, 1994; MOURA FILHO, 2009; PAIVA, 2005), as well as the use of WebQuest as an efficient tool for learning (CHRISTIE, 2007; DIAS, 2010; MARCH, 2004). In this case study, data were generated by the observation of the activities' accomplishment and the responses of nine of the participants to a questionnaire designed in the virtual environment. The results showed that the activities proposed through the WebQuest tool provided the postgraduate students with autonomy in the knowledge construction and, therefore, it was possible to notice significant changes in their attitudes in relation to learning.

Authors: Jora Rakesh , Mastan Chandradeep , Karnani Priyanka
Published: July 2020

Upper gastrointestinal (UGI) endoscopy reveals abnormal pathological findings in 55% patients of iron deficiency anemia therefore gastrointestinal pathology should be ruled out iron deficiency anemia not responding to the treatment.

To determine the role of upper gastrointestinal endoscopy and find out the pathological changes which occur in children with iron deficiency anemia (IDA)

This cross-sectional study included 95 pediatric patients with iron deficiency anemia in the age group between 3 to 17 years who underwent routine upper gastrointestinal endoscopy. All potential bleeding lesions were identified and biopsy samples were taken from 2 part of duodenum for histopathological examinations.

The mean age of cases was 7.3±3.3 years. Endoscopy revealed abnormal finding in 63.1% patients. The gastrointestinal pathologies identified were celiac disease in 22 patients, nonspecific duodenitis in 11 patients, H.Pylori duodenitis in 8 patients, erosive duodenitis in 7 patients and giardiasis in 3 patients.

Upper gastrointestinal endoscopy has a definitive role in identifying the underlying cause of iron deficiency anemia in patients not responding to conventional therapy.
Unclassified variants of hepatic artery discovered on a 40 slice multidetector CT scanner
Authors: Sharma Sachal , Singh Namita , Malhotra Payal , Kamal Murtaza
Published: July 2020

CT angiography is a common modality used to study the anatomy of hepatic arterial system. Literature reports various unclassified variants of hepatic artery, which prompted us to take this study to see the same in our cohort of population. CT angiograms were performed using 40 slice CT scanner on 110 patients for the investigation of arterial variants in case of hepatic donors and patients for aortic evaluation with angiography. The Results were analyzed as per Michels as well as Modified Michels / Hiatt classification of Hepatic artery variants. The typical/classical most common anatomy (type I variant) as proposed by Michels in 1955, was Right and left hepatic artery arising from common hepatic artery which is a branch of celiac artery. In our study we did not find any type X variant and more so vascular anatomy in 5 patients (8%) did not fit into Michels' classification or Modified Michels/Hiatt classification. These variants have not been reported before, and its importance lies in the fact that variants can predispose to increased risk of surgical complications during liver transplantation and hepatobiliary surgery. It may also influence the choice of vascular technique and materials used in interventional procedures.

Authors: Neogi Sujoy , Sengar Mamta , Mohta Anup
Published: July 2020

The recto-urethral (RUF) and recto-vestibular fistula (RVF) are varieties of anorectal malformation (ARM) with distinct clinical behaviour. In this study post-operative clinico-manometric comparison has been done.

The study was conducted for 2 year period and included post-operative cases of RUF and RVF. Post-operative follow up was done clinically and by anal manometry.

Kruskal Wallis test, Mann Whitney U test, and Spearman correlation test were done to find out the statistical significance.

A total of 21 patients with RUF and RVF were included. The average basal and squeeze pressure of RVF group was (cm H2O) 34.66 ± 13.2 and 89.35 ± 30.8 respectively. These pressures were higher than those of RUF which were 26.74 ± 12.8 and 71.20 ± 42.8 respectively. Rectoanal inhibitory reflex (RAIR) was present in 84.6% cases of RVF in comparison to 62.5% in RUF group. The mean combined (RUF + RVF) basal pressure in RAIR positive group was 32.97 ± 12.2 compared to 24.5 ± 4.6 cm HO in RAIR negative group. The mean combined squeeze pressure in RAIR positive group was 84.34 ± 36.2 compared to 68.83 ± 32.75 cm HO in RAIR negative group.

The anal pressures of RVF group were higher than RUF group. Anal pressures also higher in RAIR positive group than the RAIR negative group. Anal pressures and RAIR status may have some role in post-operative outcome in cases of ARM.

Authors: D Vaswani N , Lekhwani Seema , Swami Manish
Published: July 2020

Anemia is a major global health problem, especially in developing countries. This problem is largely preventable & easily treatable. In India prevalence is approximately 51%. The NFHS 2005-2006 revealed that at least 80% of Indian children aged 12-23 months are anemic. Most children with anemia are asymptomatic and have abnormal Hb or hematocrit level on routine screening. Anemia in infancy and early childhood is associated with behavioral and cognitive delays, and lower scores on test of mental and motor development.

To study clinical profile and factors associated with severe anemia.

This study was conducted in the Department of Pediatrics, Pt. B.D.S. PGIMS, Rohtak. The patients of age group 6 months to 59 months having severe anemia (Hb 7 gm/dl) were taken as subjects.

Out of 100 patients 51 belonged to iron def anemia (51%), 15 belongsed to megaloblastic anemia (15%). The mean hemoglobin was 5.22 that ranged from 2 to 7 gm//dl with standard deviation of 1.389. mean MCV was 76, whereas MCH, MCHC were 20 and 26 respectively. Most of anemic children belonged to grade 3 and 4 degree of malnutrition (76%).

Prevalence of anemia in children admitted at PGIMS was high. Characteristics strongly associated with severe anemia included unemployment among caregivers and malnutrition. Iron deficiency anemia and megaloblastic anemia were the common types.

Esophageal Atresia (EA) with tracheo-esophageal fistula (TEF) is a common congenital anomaly diagnosed at birth. These children either undergo primary anastomosis of esophageal pouches or a diversion procedure (cervical esophagostomy & feeding gastrostomy), depending on the gap between the two pouches intra-operatively. Sham oral feeds are encouraged in these babies in order to stimulate brain development. We present an unusual case of diverted TEF who presented to us with recurrent fever, runny nose and blood stained discharge from esophagostomy.

Authors: Oberlender Guilherme , Murgas Luis David Solis
Published: July 2020

Objetivando-se avaliar a motilidade e a taxa de degradação da motilidade (TDM) do sêmen suíno armazenado em diferentes diluidores e em diferentes volumes destinado à IAIU, foram utilizados 12 ejaculados de três reprodutores suínos. Os ejaculados foram diluídos em partes iguais com os diluidores A, B e C, classificados como de curta, média e longa duração, respectivamente. A seguir foram produzidas doses inseminantes com os volumes de 15, 20, 25 e 30 mL destinados à inseminação artificial intra-uterina. As doses com 1,5 bilhão de espermatozoides cada foram incubadas em refrigerador, a 15ºC e avaliadas com relação à motilidade e ao TDM no dia da coleta (0 hora) e nos tempos 24 e 48 horas após a coleta. O modelo estatístico utilizado foi o blocos ao acaso com parcela subdividida no tempo, em esquema fatorial 3 × 4 (três diluentes × quatro volumes de armazenamento) nas parcelas e, nas subparcelas, os tempos de avaliação (0, 24 e 48 horas). Não observou-se diferenças (P>0,05) nos diluentes sobre a motilidade espermática no tempo 0 hora. Após 24 horas, o diluidor C (longa duração) preservou a motilidade espermática, independente do volume da dose inseminante. Às 48 horas após armazenamento das doses inseminantes, a motilidade foi inferior (P<0,05) em todos os diluentes e volumes quando comparado ao sêmen in natura. Para o TDM não foram obtidas diferenças estatísticas (P>0,05) entre os diluentes e volumes avaliados. A TDM apresenta-se de forma diferente da motilidade espermática em doses inseminantes destinadas a IAIU.
Production of Inga vera Willd and Eugenia involucrata DC. seedlings fertigated with whey
Authors: Da Silva Rita de Cássia , Pinto Lilian Vilela Andrade
Published: July 2020

Residuary effluents from dairy industry contaminate hydric resources, so researches aiming sustainable methods to revert this situation must be stimulated. The objective of this study was to determine if whey can be used as fertigation and to define the proportion of whey that shall be fertigated for species Inga vera and Eugenia involucrata. This research consisted in two experiments, one with Inga vera and the other with Eugenia involucrata, since the species have distinct ecological behavior, being pioneer and late secondary, respectively. Both experiments were designed in completely randomized blocks and four fertigations were evaluated: T1: 100% water; T2: 25% whey and 75% water; T3: 50% whey and 50% water; and T4: 100% whey. The indicators evaluated were: plant height, collar diameter, aerial part weight, root weight, and development quality rate. Fresh whey promoted different responses in the development of Eugenia involucrata and Inga vera seedlings and the use of whey as fertigation for the species Eugenia involucrata is not recommended. Studies of irrigation using whey at the concentration of 100% is recommended for the production of Inga vera seedlings, daily or in alternate days, minimizing pressure on clean water availability.

Published: July 2020

Through maps, agroclimatic zoning can help us understand the guidelines for the most suitable locations for sowing, minimizing risks of produce loss due to climatic adversities. The aim of the present study is to develop an agroclimatic zoning for the cultivation of a non-irrigated off-season (safrinha) corn in the state of Goiás, sown in the first ten days of February. The methodological steps were the delimitation of the representative bands of the climatic requirements for the crop; the spatialization of the climatic elements in the region; the spatial reclassification of climatic elements based on the climatic requirements for the crop; elaboration of the agroclimatic zoning map. Average, minimum, and maximum air temperature, accumulated precipitation, actual crop evapotranspiration and relative humidity of the air registered between February and July for the years 2013 to 2017 were used. The most suitable areas for the cultivation of the non-irrigated off-season corn sown in the first ten days of February in Goiás established by the agroclimatic zoning are concentrated in the South-Southwest and Northwest regions. The expressive presence of Latosol soil class and the proximity of the values of the climatic elements accumulated precipitation, temperature and altitude, which are proper for the development of the off-season corn, favour suitability of the areas.
Effects of the Neonicotinoid Imidacloprid on the Feeding Behavior of Melipona quadrifasciata anthidioides Lep.
Authors: Costa Luiz Guilherme de Lima , Barchuk Angel Roberto , Teixeira Isabel Ribeiro do Valle
Published: July 2020

Even though meliponines are among the greatest pollinating agents in Neotropical ecosystems, the populations of these bees are in decline due to anthropic actions, such as the indiscriminate use of pesticides. Neonicotinoids, such as Imidacloprid, are used in many crops and have been shown to be one of the pesticides groups with the most damaging effects on the health of bee colonies. The goals of this work were (1) to evaluate the ability of Melipona quadrifasciata, a native Brazilian stingless bee species, to detect the presence of Imidacloprid in artificial diets, and (2) to evaluate how this insecticide may affect their behavior. For this purpose, behavioral experiments were carried out in observation arenas where artificial flowers containing different concentrations of Imidacloprid (0%, 1%, 5%, 10%, and 20%) were made available to forager bees and their choice and behavior were registered. Our results showed that bee choices were not affected by the different concentrations of Imidacloprid, even at extremely high doses in the flowers (20%). It was also found that the presence of this insecticide interfered with the communication between individuals as a result of reduced antennation events. Both findings, the apparent inability of bees to detect the presence of the insecticide and the change in behavior caused by the exposition to the volatilized product, may rapidly lead to colony losses in nature.

Published: July 2020

It is known that the use of medicinal plants can improve health, and their study in Brazil is promising due to their floristic megadiversity, mainly in Cerrado, where several traditional populations live, and many endemic species can be found. From data obtained through interviews, this research recorded the medicinal plants used by 40 residents of urban and rural areas of Sobradinho (DF), situated in Cerrado, and evaluated their socioeconomic profiles. Rural women had a greater knowledge about medicinal plants. Most of the urban population had a full college education, while most of the rural population had not completed their basic education. Although the urban population also used literature, the main source of knowledge came from family members. The level of ethnobotanical knowledge was vast in Sobradinho and similar in urban and rural areas, where the interviewees cited 86 names of medicinal plants that corresponded to 126 species, of which 56.35% were native to Brazil and 43.65% exotic. All of the species were categorized into 48 botanical families, with Asteraceae, Lamiaceae and Fabaceae being the most cited, respectively. Although they knew many native species of medicinal plants, the population used more exotic ones, such as mint, lemongrass and boldo to treat conditions such as stress, flu and indigestion, respectively.

Published: July 2020

The main characteristics of the phenolic foam are inherent to a substrate of excellent quality such as sterility, excellent aeration and high load-bearing capacity. However, as it comes from a phenolic resin, the foam has some residues that can affect the development of plants. Thus, this work aimed to evaluate different treatments for washing phenolic foam under the germination and initial growth of lettuce seedlings in two immersion times. The experimental design was completely randomized (DIC), in a 5x2 factorial scheme, containing four replications with 56 plants per plot. Each repetition was composed of a phenolic foam board. The experimental factors consisted of different substances: caustic soda (NaOH), pint lime (CaOH2), citric acid (C6H8O7), vinegar (CH3COOH) and water in solution with distilled water, and two immersion times (30 minutes and 18 hours). For the witness treatment, there was no immersion. After 18-hour immersion, the treatment with citric acid presented the best development for height and biomass in the lettuce seedlings. On the other hand, the 4,0% vinegar pretreatment was not considered viable for phenolic foam for any of the times analysed. There was a significant decrease in seedling biomass when no treatment in the foam was carried out before sowing the lettuce seeds. The caustic soda presented lower results for emergence speed index, fresh aerial biomass, height and number of leaves for the 18-hour immersion compared to the 30-minute immersion.

Published: July 2020

Invasive forage grasses, especially the Urochloa genus, impact reforestation worldwide. The aim of this study was to evaluate management influence on phytosociology of the herbaceous layer, defined as the layer of herbs, sub-shrubs, shrubs and vines, in two agroforestry systems (AFS) (Simple and Biodiverse) in succession to a reforestation of guanandi (Calophyllum brasiliense), compared to monoculture of this specie taken as control. The experiment was conducted in Pindamonhanga (SP), Brazil, from 2011 to 2014, in a randomized block design with eight replications and 144.0 m² plots. In Simple SAF area, food crops were grown alongside C. brasiliense rows: sweet cassava (Manihot esculenta) in rotation with arrowroot (Maranta arundinacea), pigeon pea (Cajanus cajan), banana shrub (Musa sp.), and juçara palm (Euterpe edulis). In Biodiverse AFS, fourteen native tree species were also planted alongside the food crops. Altogether 41 non-stratified species, 38 genera and 24 botanical families were identified; the most abundant families were: Asteraceae, Poaceae e Cyperaceae. The similarity between the areas diverged after three years of management, with the predominance of Commelina benghalensis and M. arundinacea in the AFS areas and Urochloa decumbens in the monocultive, mainly, due to the shadow gradient established for the three systems.

Published: July 2020

In this study, we evaluated the spatial-temporal changes in three subwatersheds essential for the hydrodynamics of Jaguari River (Ribeirão das Posses, Forjos and Saltos) after the implementation of the “Conservador das Águas” project in the municipality of Extrema (MG). We used satellite images from TM-Landsat-5 from year 2006 and OLI-Landsat-8 from year 2018 to map land use and vegetation cover, and the SPRING software to classify images in Geographic Information Systems (GIS) and quantify the occurrence of the classes analyzed in 2006 and 2018. After these analyses, we observed 19,77% increase in vegetation cover in the three subwatersheds. Surprisingly, we also detected a similar result in adjacent subwatersheds where the project was not implemented. Thus, this study suggests a positive effect of the “Conservador das Águas” project to the maintenance of biodiversity and hydric system functioning of that region, resulting in increased environmental quality standards and effectiveness of the environmental services for the community and its properties.

Published: July 2020

Fever is one of the most common clinical manifestations in children. During the early days of acute febrile illness, some decrease in hemoglobin levels occurs due to unspecified cause. 64 children aged 6 months to 12-year-old with a fever higher than 38° for more than one day and with a diagnosis of acute febrile illness were admitted. The values of MCV, ESR, CRP, and hepcidin were measured at baseline and then 7 to 10 days after the improvement of the fever. The levels of reticulocytes, LDH, and bilirubin were also measured in two stages. Data analysis was done using SPSS software. The mean hemoglobin level in the acute phase of febrile illness was significantly increased 7-10 days after discontinuation of the fever by 12.87±1.09 g/dl (P<0.001). The MCV level also significantly increased (P<0.001), and levels of CRP, ESR, LDH, bilirubin, and hepcidin showed significantly decreased during the convalescent phase compared to acute febrile phase, but the level of erythrocyte increased. The present study confirmed the decrease in hemoglobin in children with acute febrile illness. Increasing of bilirubin, LDH, hepcidin, level, and no bleeding was observed during acute febrile infection in children.

The outcome of inoperable rectal cancer treatment by chemotherapy, radiotherapy, and targeted therapy are still unfavorable. Carbogen is a combination of 98% oxygen and 2% carbon dioxide proven effective as chemoradiosensitizer. The aim of this study is to know the effect of concurrent carbogen and chemoradiotherapy in locally advanced rectal cancer by measuring the shrinkage of the tumor volume. The design of this study was randomized true experimental 2 groups pre and post-test-controlled design. Samples were patients with locally advanced rectal cancer. MRI of the pelvis before and 4-8 weeks after the chemoradiation were examined. A total of 28 subjects were randomized to 14 patients who received concurrent chemoradiation with carbogen (treatment group) and 14 patients chemoradiation (control) The tumor shrinkage in the treatment group (13.08 to 6.08 cm3 ) was significantly higher compared to the control group (18.00 to 12.83 cm3 ). Supplementation of carbogen to standard treatment chemoradiation for locally advanced rectal cancer significantly shrinkage the tumor volume.

Quality of life of patients in need of liver transplantation is impaired due to many reasons, and this affects the pre and post outcomes and complications of transplantation. Therefore, the aim of this study was to evaluate the effect of a care program on the quality of life of patients awaiting liver transplantation. This quasi-experimental study was conducted in 2017 on 117 patients awaiting liver transplantation in Imam Khomeini Hospital of Tehran. Based on entry criteria, the samples were selected purposefully, and their quality of life was evaluated. Then, a care program in 6 one-hour-long sessions for 2 months was implemented for them. This program was according to patients' needs, including disease and transplant process education with using multiple educational methods. The data collection tool was a quality of life questionnaire (1999), which was completed before and six weeks after the intervention. The results showed that the overall quality of life and its entire aspects improved after the implementation of care program in patients waiting for liver transplantation, and the most change was related to the aspect of systemic (P<0.01). Also, the demographic variables had no significant relationship with the aspects of quality of life. The results of this study indicated a positive effect of the care program on improving the quality of life of patients awaiting liver transplantation. Eliminating the problems of these patients requires the attention and support of planners and the cooperation of managers in order to develop care programs that can be used by healthcare professionals, especially nurses.

Obesity is one of the major health issues in developed and developing countries, which has been increasing in recent decades. Obesity is one of the important risk factors for type 2 diabetes by developing insulin resistance. The purpose of this study was to investigate the effect of vitamin D on insulin resistance in overweight and obese children and adolescents with vitamin D deficiency. In this interventional study, 53 overweight and obese children and adolescents with vitamin D deficiency referred to the Endocrinology Clinic of Shahrekord University of Medical Sciences were included. The height and weight of participants were measured, and their Body Mass Index (BMI) calculated. To participants, 50,000 units of vitamin D were administered weekly for 8 weeks, and then 1000 units were orally administered daily for 3 months. Before and after the intervention, levels of vitamin D, insulin, and fasting blood sugar were measured. The HOMAIR was also calculated as an indicator of insulin resistance. After the intervention, serum vitamin D significantly increased, and BMI and fasting blood sugar significantly decreased (P<0.05). The insulin resistance index did not change significantly during the intervention (P>0.05). After the intervention, HOMA-IR had a significant direct correlation with body mass index, insulin, and fasting blood sugar and a significant inverse correlation with vitamin D (P<0.05). Vitamin D had a significant inverse correlation with BMI, insulin, and fasting blood sugar after the intervention (P<0.05). Oral treatment with vitamin D significantly increased serum vitamin D levels and significantly decreased BMI and fasting blood sugar in obese and overweight children.

The Oxygenation Index (OI= [MAP×FiO2]/PaO2×100), an invasive diagnostic criterion, is routinely used as a marker of severity of acute respiratory distress syndrome (ARDS). In order to determine of OI, arterial blood gas (ABG) through an invasive procedure is indispensably used to obtain PaO2. The Oxygenation saturation Index (OSI= [MAP×FiO2]/ SPO2 ×100), as an alternative method, can be implemented using pulse oximetry to assess SpO2. For this epidemiologic-analytic study, 74 intubated patients admitted in a pediatric intensive care unit of Abouzar hospital of Ahvaz during the first 3-day admission were selected equally in pulmonary and non-pulmonary groups within a six months period, from January 1, 2019, to May 31, 2019. Two indexes of OI and OSI in both patients were evaluated, and eventually, the results were analyzed by linear regression using Spss. A comparison of the two OI and OSI indexes showed a meaningful relationship was found (P<0.001), which has a higher correlation coefficient of 0.726 in patients with the pulmonary disease than non-pulmonary patients with 0.394. The present study demonstrates that the index of oxygen saturation (OSI) with a sensitivity of 78% and specificity of 83% in the patients without acute pulmonary distress syndrome is a suitable indicator instead of the invasive index of OI. Also, in patients with pulmonary disease that meet the medium range of Berlin criteria, with a sensitivity of 100% and specificity of 76%, the OSI index can be used to predict the status of patients.

Background: The attempt to manage patients with acute myeloid leukemia as outpatients has become increasingly common due to high hospitalization costs, low availability for beds and patient preference. Publications on the subject are scarce, especially in low-income regions and the safety in this population remains to be determined. The present study aims to assess the safety of consolidation with high-dose cytarabine in the outpatient setting.
Materials and Methods: We retrospectively analyzed 39 patients who underwent consolidation with highdose cytarabine, between 2009 and 2018, at Ophir Loyola Hospital, in Belém, Brazil. Patients treated after 2015 were given high-dose cytarabine as outpatients due to the decision of medical staff.
Results: Twenty-seven patients received 76 cycles of cytarabine as outpatients; males were 48.14% of the total population, with a median age of approximately 45 years. The occurrence of delay between cycles was significantly lower among outpatients (48.14% vs. 83.33%, p = 0.04). There was no difference in relapse rates, transfusion requirements and non-relapse mortality between both groups. Hospitalization was required in 40.74% of patients during outpatient cycles and 18.51% of blood cultures were positive for pathogens. Nonrelapse mortality was significantly higher among patients above 50 years old and treated on an outpatient basis (44.4% vs. 5.60%, p = 0.03).
Conclusion: High-dose cytarabine administration on an outpatient basis appears to be safe and effective in a low-income population at the Brazilian Amazon region, but toxicity seems to be increased for patients older than 50 years.

Hereditary hemolytic anemias present a unique diagnostic challenge due to their wide phenotypic and genotypic spectrum. Accurate diagnosis is essential to ensure appropriate treatment. We report two cases, which presented as hemolytic anemias, but initial workup was inconclusive and they were finally diagnosed with the help of Next Generation Sequencing (Dehydrated Hereditary Stomatocytosis and Kӧln Hemoglobinopathy). The introduction of gene sequencing to aid diagnosis of these disorders is a revolutionary step forward and should be incorporated earlier in the workup of such patients.

Published: July 2020

Background: Intramedullary nailing (IM nailing) is the standard of care for the treatment of most diaphyseal lower extremity fractures. A few studies have assessed and compared the infection rate following reamed and unreamed IM nailing in open long bone fractures. In the present study, we attempted to compare the infection rate between two procedures in open fractures of tibia.
Methods: In this prospective study, we included consecutive patients suffering from open fractures of tibia (Gustilo subtypes II or IIIA) who required IM nailing. Patients younger than 16 years old, other Gustilo types (I, IIIB, and IIIC), fractures reaching to the tibial plateau articular surface, and simultaneous fractures of other bones in the extremity were excluded. All patients were followed up for one year to assess the postoperative infection rate.
Results: Of 59 patients, 37 underwent reamed IM nailing and 22 underwent unreamed IM nailing. In reamed group, 4 cases (10.8%) experienced an infection requiring reoperation and antibiotic therapy, while in the unreamed group, it was 5 cases (22.7%). The difference between the groups was not statistically significant.
Conclusion: Reamed and unreamed IM nailing procedures for fractures of tibia have similar outcome regarding long-term postoperative infections that require reoperation and antibiotic therapy.

Introduction: Alzheimer disease (AD), known to be a leading cause of dementia that causes heavy social and financial burdens worldwide, characterized by progressive loss of neurons and synaptic connectivity after depositions of amyloid-β (Aβ) protein.AD manifests as an impaired ability to comprehend or use words, poor coordination and gait, and impaired executive functions in the realms of planning, ordering and making judgments. Generally, classification of AD includes familial and sporadic AD. Current therapies for AD patients can only alleviate symptoms, but cannot deter the neural degeneration, thus providing no long-term recovery. Stem cells are undifferentiated cells that have a potential to produce many different cell types in the body. A vast amount of data indicates the potential of stem cell therapy for various neurological diseases. Several studies revealed that neurons and glial cells have successfully been differentiated from various stem cells. Thus, in this article, we review the treatment of Alzheimer\ disease by various types of stem cells.

Introduction: Menopause is the natural termination of menstruation, which affects the quality, and important aspects of women life. The aim of this study was to investigate regular resistance training along with vitamins D and calcium intake in the pre-menopausal period on bone mineral density (BMD) in rats.
Methods:  In this experimental study, the rats were randomly divided into control groups, placebo, vitamin D, calcium, resistance training, vitamin D + calcium, vitamin D + resistance training, calcium + resistance training, vitamin D + calcium + resistance training. Control and placebo groups were fed with a standard diet and sesame oil, respectively. Ovariectomy was done after two months of resistance training (Ex), calcium (35 mg/kg) and vitamin D (10000 IU) administration. BMD and bone mineral content (BMC) were measured. Hematoxylin-eosin staining was performed to examine bone total diameter and osteoclast and osteocyte cell numbers. The statistical analysis was done by a one-way analysis of variance (SPSS 20).
Results: There was an increasing trend in BMD lumbar of the Ex group (P<0.001) in comparison with the control group. The amount of bone mineral in the whole body in calcium and calcium + resistance groups was higher than the control group (P <0.05). BMC total in the vitamin D, calcium + resistance training, vitamin D + resistance training and calcium + vitamin D + resistance-training groups was lower than the other groups. Osteoclast cell numbers were decreased in Ex, Vit D+Ex (P<0.05), Ca+Vit D, Ca+Ex and Ex+Vit D+Ca groups (P<0.001) compared to the control group, also, osteocyte numbers were decreased in VitD, Ca+Vit D (P<0.05), Ex, Vit D+Ex, and Ex+Vit D+Ca groups (P<0.001).
Conclusion: Regular resistance exercise, vitamin D and calcium supplements in pre-menopausal period can improve BMD and BMC and delay the process of osteoporosis in postmenopausal period.
