BACKGROUND Cutaneous leishmaniasis (CL) is a major health problem in many parts of Iran, although diagnosis of CL especially in the endemic area is easy, but treatment and management of the disease is a global dilemma. Diagnosis of CL in non-endemic area is not as simple as in endemic foci. In this study, the status and the proportions of CL induced by Leishmania major and L. tropica among CL s...

CONTEXT Endemic area and iodine supplementation may affect the pathogenesis of the nodule which commonly occurs in endemic thyroid enlargement due to iodine deficiency. AIMS To establish pathological changes in solitary solid and larger nodule of the thyroid in endemic area. SETTING AND DESIGN Retrospective study in Surgical Department of University Hospital. METHODS AND MATERIAL We deter...

Relapse may have evolved in malaria as a mechanism to avoid suppression by more virulent species in mixed infections, thereby increasing transmission opportunities. Later evolution of long latency in Plasmodium vivax was a necessary adaptation as early hominins moved to colder areas with shorter mosquito breeding seasons. Genetic diversity was maintained through heterologous hypnozoite activation.

377 patients with single thyroid nodule who clinically were candidates for surgery, were selected from the patients that referred to the clinics of endocrinology at namazee hospital, shiraz medical school. fine needle aspiration (fna) was carried out without performing thyroid scan and the results were compared with histology obtained by surgery to establish its accuracy in our center. which is...

Epstein-Barr virus (EBV)-encoded small RNAs (EBERs) are the most highly expressed transcripts in all EBV-associated tumors and are involved in both lymphoid and epithelioid carcinogenesis. Our previous study on Chinese isolates from non-endemic area of nasopharyngeal carcinoma (NPC) identified new EBER variants (EB-8m and EB-10m) which were less common but relatively more frequent in NPC cases ...

Malaria is endemic in many tropical and subtropical regions of the world, including Saudi Arabia. The infection has serious consequences in those residing in non endemic regions on travelling to endemic areas, due to lack of immunity to the parasite. In this report, we describe the clinical course of two patients who travelled to a malaria endemic area. Both contracted the infection and present...
