Abstract
Background and Aim: There are some reports regading the anti-inflammatory and antimicrobial effect of honey and Nigella sativa and their therapeutic effects in improvement of wound healing. This study was designed to evaluate the efficacy of adding honey and Nigella sativa extract compared to honey alone in patients with cutaneous leishmaniasis receiving intralesional Glucantime.
Methods: In this clinical trial, 150 patients with confirmed cutaneous leishmaniasis were randomly allocated into two groups. One group was treated with topical honey twice daily along with weekly intralesional injection of Glucantime. In the second group, patients were treated with topical honey and 60 % hydroalchoholic Nigella sativa extract instead of honey alone. The patients were treated until complete healing of the ulcer or for maximum of 12 weeks.
Results: At 12 weeks, complete cure was achieved in 61 (81.3%) of patients treated with topical honey and 60 % hydroalchoholic Nigella sativa extract versus 48 (64%) in the second group (P=0.002).
Conclusion: The efficacy of adjunct honey and Nigella sativa extract along with intralesional Glucantime is more than honey alone in increasing complete cure rate and decreasing the residual scar size and the required dose of Glucantime.

Abstract
Background and Aim: The heterogenous population of memory T lymphocytes is distinguished based on surface markers and effector functions such as cytokine secretion. Recently, two subsets of memory T cells are defined by expression of chemokine receptor CCR7 and CD45RA designating as "central memory" T cells (TCM) and "effector memory" T cells (TEM). The objective of this staudy was to evaluate the phenotype and function of these lymphocytes in healed cases of cutaneous leishmaniasis.
Methods: The phenotype of lymphocytes were determined in blood samples of 13 volunteers with history of self healing cutaneous leishmaniasis (HCL) and in 6 healthy controls.
Results: No significant difference was found in memory T cell subsets between HCL volunteers and healthy controls using flow cytometry. However, following sorting of different memory subsets, a significantly higher proliferation was seen in cells of HCL volunteers comparing to the control group. A significantly higher IFN-γ response in TEM and a significantly higher IL-2 response in TCM were observed in cell culture of HCL volunteers comparing controls.
Conclusion: The responses were elicited when the cells were stimulate with SLA in vitro, it is concluded Leishmania-specific TEM and Leishmania-specific TCM subsets exist in HCL volunteers and since the volunteers with history of CL presumed to be protected against reinfection, it seems that both TCM and TEM play role in the protection against Leishmania infection in these individuals.

Abstract
Background and Aim: Treatment of cutaneous leishmaniasis, especially when caused by L. tropica, is challenging. Meglumine antimoniate (Glucantime®) is used as the standard treatment, but multiple injectiond are necessary. The objective of this study was to compare the efficacy of weekly intralesional injections with twice weekly injections of Glucantime for the treatment of anthroponotic cutaneous leishmaniasis (ACL).
Methods: This randomized open clinical trial was conducted, in Bam, Kerman province, Iran. 96 eligible patients according to inclusion and exclusion criteria who were willing to participate were included. The included patients were randomly assigned into two groups, one group treated with weekly intralesional injections of Glucantime® and the other group treated with intralesional Glucantime® twice a week. Type and size of each lesion (induration, ulcer and scar) were recorded weekly. Complete healing was defined as complete re-epithelialization and absence of induration in all lesions and was considered as the primary outcome measure.
Results: A total of 48 patients completed the study complete cure was seen in 24 of 27 (89%) patients who received weekly intralesional MA with a mean duration of healing equals to 70±10 days. Complete cure was seen in 24 of 31 (77%) patients who received intralesional MA twice a week, the mean duration of healing in the latter group was 58±5 days. There was no significant difference between the two groups (P=0.23).
Conclusion: It seems that the efficacy of intralesional injections of Glucantime® once a week is similar to efficacy of twice a week Glucantime® injections.

Abstract
Background and Aim: Cutaneous leishmaniasis (CL) is endemic in Iran, where it is one of the most important health problems. Both anthroponotic CL (ACL) caused by L. tropica and zoonotic CL (ZCL) caused by L. major are reported. Antimoniate derivatives as the standard therapy for CL need multiple injections and are not easy to tolerate for the patients. This study was conducted in Mashhad to compare the efficacy of weekly versus twice a week intralesional injections of meglumine antimoniate (MA) in the treatment of ACL.
Methods: This randomised controlled trial was performed during 2006 to 2008 in Mashhad, Iran. Using computerized sequence of random numbers, participants were randomly allocated in the two arms of the study: one receiving weekly and the other receiving twice-a-week intralesional injections of MA. The lesion size, induration and healing rate were assessed, recorded and compared. Healing was defined as complete re-epithelialisation and disappearance of induration.
Results: A total of 252 suspected CL patients with 372 lesions were screened. 82 parasitologically proven cases with 121 lesions caused by L. tropica were included and 74 patients with 113 lesions completed the study. At 12th week after initiation of treatment, complete healing was observed in 38 out of 44 lesions (86.4%) in the group which received weekly intralesional MA injection. The median time-to-heal in this group was 36 days (95% confidence interval [CI]: 32.0-39.9). Complete healing was recorded in 60 out of 69 lesions (86.9%) in the group which received twice a week intralesional injections of MA with a median time-to-heal of 25 days (95% CI: 20.9-29.1). While no significant difference was observed between the two groups in terms of complete healing rate (P=0.999), time-to-heal was significantly different between the 2 groups (P=0.003).
Conclusion: It seems that the effectiveness of twice-weekly intralesional injections of MA is similar to once-weekly regimen while the former regimen causes more rapid healing of lesions.

Abstract
Background and Aim: The aim of this study was to investigate various aspects of the treatment in patients with cutaneous leishmaniasis in Iran in the first half of 2014.
Methods: This cross sectional study was conducted on the existing data of 3684 patients with cutaneous leishmaniasis, whom were registered at the Disease Management Center of the Iranian Ministry of Health in the first half of 2014. Version 11 of Stata was used for statistical analysis and the level of significance was considered equals to 0.05.
Results: Of 3684 patients entered into the study (%55.1) were male and the mean age of the patients was 27±18 years. More than 34% of patients were treated with intralesional injections of meglumine antimoniate (MA) and 25% of patients recieved systemic MA injections. There were statistically significant correlations between the size and number of the lesions and the chosen treatment regimen (P<0.001). Thirty-five percent of patients treated with systemic MA between 7 to 10 days and 43.3% of patients recieved intralesional MA injections for 5 to 8 weeks.
Conclusion: More than %99 of patients fully recovered without complication or treatment failure. It seems that Iranian patients suffered milder CL in comparison with some other coutries.

Abstract
Background and Aim: Lack of information on how to protect and prevent cutaneos leishmaniasis plays an important role in the susceptibility to the disease. Therefore, preventive measures will be effective if the parents have awareness about the disease. This study was aimed to invetigate the effects of educational interventions on mother’s knowledge and attitude towards cutaneous leishmaniasis.
Methods: In this quasi-experimental study, 120 married women who were 15 years of age or older and were referred to Ab-o-Bargh Health Center in Mashhad were recruited. The participants were divided into three groups: participation in an educational lecture, participation in an educational group discussion session, and a control, non-intervention group. A researcher-developed questionnaire including questions on demographic data, and developed knowledge and attitude towards cutaneous leishmaniasis were used for data gathering. The evaluation of educational intervention effects were assessed before, immediately after the interventions, and one month after the educational interventions.
Results: Before the intervention, there was no significant difference in the mean of awareness scores between the three groups (P=0.71). However, there was a significant difference in awareness scores between the three groups immediately after the intervention. The observed scores did not change significantly after one month (P=0.001). Also, there was there was a significant difference in the rate of attitude score towards cutaneous leishmaniasis after the intervention between three groups (P=0.001).
Conclusion: Individual and group educational interventions regarding cutaneous leishmaniasis were effective to increase the knowledge and improve the attitude of the participants towards the disease. We recommend to apply effective educational interventions like group discussions to improve the mothers' knowledge and their insights about cutaneous leishmaniasis.

Abstract
Leishmaniasis is a group of diseases which is caused by an intracellular protozoal infection. It is the third most common opportunistic infectious disease in HIV positive patients worldwide. In this article, we present a 30-year-old women who was a known case of HIV/AIDS infection and developed multiple papules and nodules as on her face, arm and shoulder with diagnoses of diffuse cutaneous leishmaniasis. PCR was performed for determination of parasites species and Leishmania tropica was identified as the causative agent. The patient was treated with parenteral amphotericine B and topical neosomal paromomycin for 3 weeks and all lesions healed without scaring.
She discontinued her anti-retroviral therapy a few months later and the lesions recurred. Finally, she died due to sepsis and pulmonary emboli.

Abstract
Background and Aim: The most prevalent form of leishmaniasis is cutaneous leishmaniasis (CL), which manifests as a single ulcerative or nodular lesion that usually heals on its own. The aims of this study were to investigate the histopathologic and clinical features of CL patients.
Methods: This cross-sectional study was accomplished on 70 CL patients that referred to Razi dermatology hospital in Iran, over a five-year period from 2016 to 2020. Included patients were those who were diagnosed clinically suspected patients whom their disease was confirmed through histopathology examination.
Results: The age of patients ranged from 2 to 76 years with a mean of 42.26 ± 20.86 years. The majority of patients were men (54.3%). The plaque form lesions were the most frequent type (64.3%). Respecting lesion site, face, and upper limbs were more frequent with the abundances of 47.1% and 34.3%, respectively. All of the patients had evidence of cellulitis on ultrasound. The most prevalent change of epidermis was hyperkeratosis (42.8%). Regarding dermal histopathologic changes, infiltration of lymphocytes (61.4%), plasma cells (58.6%), and histiocytes (48.6%), as well as granuloma formation (54.3%) and leishman body presence (54.3%) were the dominant changes. Some patients had atypical forms of CL as six of them had lupoid cutaneous leishmaniasis (LCL) and five had sporotrichoid cutaneous leishmaniasis (SCL).
Conclusion: In this study, men and those who were in middle age were more susceptible to be infected, so it suggests considering them particularly in the preventive programs. Moreover, histopathological findings of CL, including LCL and SCL, are presented. These findings may be beneficial for dermatologists and dermatopathologists to differentiate them from other cutaneous diseases.
