An empirical study to measure the relationship between management style and conflict management

Leadership plays an important role among five main components of management. These days, many organizations try to resolve any existing conflicts through adapting an appropriate leadership strategy. During the past few years, there are increasing interests in examining the relationship between management style and conflict management. The proposed study of this paper performs an empirical study to find the relationship between relationship-oriented leadership style and solution-oriented strategy as well as between leadership style and conflict management. The proposed study distributed a questionnaire among 43 managers who were in different industries in west part of Iran. Most of the people who participated in our survey were male and they were between 25 to 30 years old. The study considers relationship between leadership style and conflict management, which includes the relationship between relationship-oriented and task-oriented leaderships with avoiding conflict management strategy, solution and control based conflict managements. The results confirmed that there is only a meaningful relationship between relationship-oriented leadership with solution-based conflict management. In other words, our survey indicates that when there is a conflict, management can handle the problem using his/her relationship and find appropriate solution to resolve any possible conflict

Effect of Low-level Laser Therapy With Different Locations of Irradiation on Postoperative Endodontic Pain in Patients With Symptomatic Irreversible Pulpitis: A Double-Blind Randomized Controlled Trial

Introduction: This double-blind, placebo-controlled, clinical trial aimed to investigate the analgesic efficacy of low-level laser therapy (LLLT) with two different locations, and their comparison, in postoperative endodontic pain (PEP) levels in molars diagnosed with symptomatic irreversible pulpitis.Methods: Seventy-five patients with a molar tooth, diagnosed with symptomatic irreversible pulpitis, were divided into three groups of placebo, buccal only irradiation (BI), and buccal and lingual irradiation (BLI), with 25 cases being in each group. The participants received similar singlevisit nonsurgical endodontic treatments. Then, a sham laser was used in the control group instead of LLLT. Individuals in BI and BLI groups received 80-second irradiation on the buccal surface and 80-second irradiation on each of the buccal and lingual surfaces respectively. A laser with an 808 nm wavelength, power of 100 mW, a fiber diameter of 600 μm, and a dose of 70 J/cm2 was used. PEP was assessed using a 0-100 mm VAS 4, 8, 24, and 48 hours after the treatment.Results: BLI showed a significantly higher reduction of PEP compared to placebo in all time intervals of this study. BLI was significantly more effective than BI 8 hours after the treatment. However, intragroup differences between BLI and BI groups at other time intervals and between BI and placebo groups in all time intervals were not significant. The number of taken analgesics in the BLI group was significantly lower than the placebo group and was on a statistical borderline compared to the BI group.Conclusion: LLLT with BLI was an effective measure as a supplement to oral analgesics in the reduction of PEP compared to the placebo

Iranian Native Plants on Treatment of Cutaneous Leishmaniosis: A Narrative Review

Background: Chemotherapy still relies on the use of pentavalent antimonials, amphotericin B, paromomycin, miltefosin, and allopurinol. In this study, we explained about the native plant that grows in different regions of Iran and used as anti-leishmanial in Iran and even many other countries. Methods: This narrative review covers all information about local herbal medicine in Iran that used in treatment of cutaneous leishmaniasis in all the worlds, published in local and international journals from 1996 to 2015 using various databases including PubMed, SID, Google Scholar, Scopus, and Science Direct. Results: Overall, 150 articles in databases were identified. Many local plants grown in some places of Iran were used to treat this endemic disease. Conclusion: The cutaneous leishmaniasis is also a major health problem in Iran, especially in Mashhad (Northeast of Iran). Therefore, many patients seek for herbal therapy that is cheaper and readily available. This review provides information regarding plant that exists in Iran and exhibiting effects on anti- Leishmania activity. Among the anti-leishmanial mentioned in this review, most have never been tested for cytotoxicity and very few have been tested for in vivo activity

Antileashmanial activity of Artemisia sieberi essential oil against Leishmania infantum in vitro

Background and aims: VL (Viseral Leishmaniosis) the second- most dreaded parasitic disease after malaria is currently endemic in 88 countries. Artemisia sieberi is native medicinal plants in Iran and their effects are scientifically proven to be effective on leishmaniasis. The aim of this study was to investigate antileishmanial effects of A.sieberi essential oil on Leishmania infantum in vitro. This is the first application of A. sieberi for treatment of L.infantum. Methods: Promastigotes of L. infantum were treated by A. sieberi in 1, 5, 10, 15, 20 μg/ml concentration. MTT test ([3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide] was done in 48h after treatment to determine the effect on promastigote viability. The data were analyzed by SPSS, and using one-way ANOVA and Mann Whitney tests. Results: Fewer than 15 μg /ml concentrations of A. sieberi essential oil were no appreciable effect on the parasite. A dose of 15, 20 μg/ml showed growth inhibitory on L. infantum in 24h/48h compared to control group (P<0.05). Conclusion: The A. sieberi essential oil had antileishmanial effects against L.infantum in vitro. Therefore, they might be a reliable source for preparation of new drugs. More in vivo investigations are required to clarify details of effects of A.sieberi on leishmania spp and analysis of its natural components

Adult emergency department performance in the largest teaching hospital in southern Iran: a 1.5-year cross-sectional study

Background: Emergency department (ED) is one of the most important hospital departments, with significant effects on public health. The aim of this study was to evaluate the adult ED's performance of the largest teaching hospital in southern Iran. Methods: In this retrospective cross-sectional study (March 2017-August 2018), the registered data in the Hospital Information System (HIS) were collected, and the ED’s performance was assessed based on the Iranian emergency performance index. The slopes of the trend lines were calculated for each indicator. Moreover, 2 six-month periods were compared. Results: The data of 104,081 patients were analyzed. The mean (±standard deviation) of visited patients per-month was 5,782.28 (±1258.55). The slope of the trend line was negative for all indicators, except for discharge from ED with personal responsibility. The mean duration of waiting time for the first visit by physician in each triage level slightly decreased. Comparison of the two six-month periods showed a significant difference between the visited patient (P&lt;0.0001). The percentage of patients disposed within six hours (P&lt;0.0001), leaving ED within 12 hours (P&lt;0.0001), as well as the percentage of successful cardiopulmonary resuscitation (P=0.014) in the six-month period of 2018 was significantly lower. The percentage of discharge with personal responsibility significantly increased (P=0.005). Conclusion: Although the number of patients visited in this ED decreased, all indicators had dropped. However, the percentage of discharge with personal responsibility was increased. Moreover, the mean duration of waiting time for the first visit by physician slightly decreased in each triage level

Changes in the Epidemiology of Cutaneous Leishmaniasis in Northeastern Iran.

The province of Khorasan-Razavi in the North East of Iran is an endemic area for anthroponotic cutaneous leishmaniasis (ACL caused mainly by Leishmania tropica) and zoonotic cutaneous leishmaniasis (ZCL caused mainly by Leishmania major). Based on clinical signs, some cities were considered as ACL foci while others were considered to be endemic for ZCL. This paper reviews studies performed on patients diagnosed with cutaneous leishmaniasis (CL) via the use of direct slide examination, ELISA, electrophoresis isoenzyme, RAPD PCR and PCR in Mashhad; the study also includes cases of CL in other cities of the Khorasan-Razavi province where only PCR used as a diagnostic tool. The data show that both Leishmania tropica and Leishmania major caused CL in most of the cities investigated. Our review shows that Leishmania major was found in areas where ACL is prevalent and Leishmania tropica was observed in areas with high incidence of ZCL. This distribution represents a major change in the epidemiological pattern of Leishmania in the Khorasan-Razavi province

Genotyping of Echinococcus granulosus Isolates from Human in Khorasan Province, North-Eastern Iran

Background: Human hydatidosis is endemic in northeastern Iran. The present study aimed to investigate molecular diversity of Echinococcus granulosus isolates collected from human surgically. Methods: Sixty human hydatid cysts (58 lung cysts and 2 liver cysts) were collected through surgery from Ghaem and Emam Reza hospitals in Mashhad University of Medical Sciences during 2015-2016. Cysts were characterized using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the internal transcribed spacer 1 (ITS1) gene and sequencing fragments of the genes coding for mitochondrial cytochrome c oxidase subunit 1 (cox1) and NADH dehydrogenase subunit I (nad1). Results: Overall, 55 out of 60 Echinococcus granulosus cysts (91.6%) were determined as the G1 strain, 4 cases (6.6%) were determined as the G6 strain and 1 sample was not identified. Conclusion: Although sheep strain (G1) is dominated in human patients in Great Khorasan, the prevention of camel-dog cycle should pay attention in this region

Fish tank granuloma: An emerging skin disease in Iran mimicking Cutaneous Leishmaniasis.

OBJECTIVE: Mycobacterium marinum causes a rare cutaneous disease known as fish tank granuloma (FTG). The disease manifestations resemble those associated with Cutaneous Leishmaniasis (CL). The aim of this study was to determine whether FTG was the cause of cutaneous lesions in patients who were referred to the Parasitology laboratory of Imam Reza Hospital in Mashhad to be investigated for CL. MATERIALS/METHODS: One hundered patients, clinically diagnosed with CL between April 2014 and March 2015, were included in this study. Ziehl-Neelsen staining was performed to identify acid-fast Mycobacterium in addition to bacterial cultures using Löwenstein-Jensen medium. Skin lesion samples were also collected and kept on DNA banking cards for PCR testing. RESULTS: Twenty-nine of the 100 individuals with skin lesions, and therefore suspected of suffering from CL, tested positive for Mycobacterium marinum by PCR. Of these, 21 (72.4%) were male and 8(27.6%) were female. In 97% of these cases the lesions were located on hands and fingers. These patients had a history of manipulating fish and had been in contact with aquarium water. A sporotrichoid appearance was observed in 58.6% of the patients with mycobacterial lesions; 67% of patients had multiple head appearance. CONCLUSION: Patients suspected to have CL and who test negative for CL could be affected by FTG. Therefore, after obtaining an accurate case history, molecular diagnosis is recommended for cases that give a negative result by conventional methods.Internal fundin

The Golden jackal (Canis aureus) as an indicator animal for Trichinella britovi in Iran

Nematodes of the genus Trichinella are zoonotic parasites causing trichinellosis. In Iran, these parasites occur in several animal species and rare cases have been recorded in humans. To monitor the epidemiological pattern of these parasites in the Khorasan-e-Razavi province, Northeastern Iran, muscle tissues were collected from the tongues of roadkill animals between 2016 and 2017: 295 stray dogs, one red fox (Vulpes vulpes), 12 golden jackals (Canis aureus), and one wild boar (Sus scrofa). Trichinella spp. larvae were retrieved using the artificial digestion method and identified to the species level by multiplex PCR. Larvae identified as Trichinella britovi were detected in five stray dogs (1.7%) and one golden jackal (8.3%). The results confirm the circulation of T. britovi in animals of the Khorasan-e-Razavi province, as previously documented. A review of the literature on Trichinella spp. in animals in Iran showed that these parasites were previously detected in 20.02% and 0.04% of carnivore and omnivore mammals, respectively, and that golden jackals can be screened as indicator animals for these zoonotic nematodes. Convenient sampling of Trichinella susceptible roadkill animals may provide a suitable method of monitoring the circulation of these parasites within any given region
