RESUMO
CONTEXT: Cutaneous leishmaniasis (CL) is an endemic parasitic skin disease in many parts of Iran including Khorasan province. Both clinical forms of the disease, anthroponotic cutaneous leishmaniasis (ACL) and zoonotic cutaneous leishmaniasis (ZCL) are present in this province. However, leishmaniasis molecular map is determined in four cities of Khorasan, but several foci still are remained unknown. AIM: The aim was to identify the species of Leishmania causing CL in Khaf, a District in Khorasan-e-Razavi province. MATERIALS AND METHODS: Slide smears obtained from skin lesions of 120 patients suspected to leishmaniasis. Direct microscopy and polymerase chain reaction (PCR) performed using specific kinetoplast DNA primers. Data were analyzed with the use of SPSS. RESULTS: Among 120 persons with skin ulcers suspected to CL, the results of direct smear of 54 (45%) samples were positive. PCR band were observed in 66 (55%) of examined samples in which 46 bands identified for Leishmania tropica and 20 for Leishmania major. CONCLUSION: Both ACL and ZCL are present in Khaf. L. tropica is the dominant causative species for ACL. Further study is recommended to discover probable reservoir and vector for L. major in Khaf.
RESUMO
INTRODUCTION: Androgenetic alopecia (AGA) is one of the most common dermatologic disorders with a multifactorial etiology. Inflammatory activators such as Demodex infestation may play a role in the pathogenesis of some cases of androgenetic alopecia that do not respond to common treatments such as minoxidil and finasteride. The goal of this study is to evaluate the relationship between Demodex infestation and AGA. MATERIALS AND METHODS: In this case-control study, 41 patients with AGA referred to the Dermatology Clinic of Imam Reza Hospital and 33 healthy individuals were evaluated as control. All of them were between 20 and 40 years old men. In order to identify Demodex infestation they were referred to the Parasitology laboratory. RESULTS: Demodex was detected in 19.5% of patients and 15.2% of controls; therefore, there was no significant relationship between them statistically (P = 0.0787). Most of patients (85.4%) had greasy hair. The most common pattern of baldness was II degree in Hamilton scale. CONCLUSION: There is no relation between AGA and Demodex.
RESUMO
Only a few cases of Acanthocephala infections have been reported in humans, and Moniliformis moniliformis is the most common species around the world. We report here a case of infection with M. moniliformis, which passed in the stool of a 2-year-old girl in Iran. The patient had abdominal pain, diarrhea, vomiting, and facial edema. According to her mother, the patient had habit of eating dirt and once a cockroach was discovered in her mouth. In stool examination, eggs of M. moniliformis were not found. She was treated with levamisole and the clinical symptoms reduced within 2 weeks. The specimen contained 2 pieces of a female worm with a total length of 148 mm lacking the posterior end. The spiral musculature of the proboscis receptacle and the shape of the trunk allowed its generic determination. Previously 2 cases of M. moniliformis infection were reported in Iran. This is the 3rd case of M. moniliformis infection in Iran.
