BACKGROUND Interleukin-1 (IL-1) is one of the cytokines produced by macrophages, monocytes and dentritc cells. Macrophages are present in apical granuloma and the wall of the radicular cyst. This cytokine causes the cyst expansion and is involved in proliferation of fibroblasts in the cyst wall and stimulate the fibroblasts to produce more prostaglandin. Radicular cyst is the most common cyst o...

BACKGROUND The radicular cyst is very common odontogenic cyst of the jaws, which is usually associated with a tooth with necrotic pulp. The cyst formation requires proliferation of the epithelial rest cells of Malassez present in the periodontal ligament. Proliferation of epithelial rest cells of Malassez is an essential event in the Pathogenesis of radicular cyst. The wall of the cyst contains...

CLINICAL CASE A 5 year-old child diagnosed with moderate anisometropic amblyopia secondary to primary cyst of iris pigment epithelium. He was evaluated with ultrasound biomicroscopy (BMU) and optical coherence tomography (OCT) of anterior segment. DISCUSSION The OCT, although with some limitations, is a useful tool to study the anterior segment. It is probably more recommendable than BMU in t...

The prevalence of vaginal cysts is uncertain since many go unreported but it estimated that 1 out 200 women have a cyst. We report case 23-year-old female with secondary infertility an incidental asymptomatic cyst, which was originally misdiagnosed as endometriotic performed the surgical treatment negative hysterolaparoscopic findings, only to identify paravaginal sebaceous cyst on exploration....

BACKGROUND Previous studies have shown that the expression and distribution of keratinocyte growth factor (KGF), also known as FGF-7 (fibroblast growth factor-7) or HBGF-7 (heparin-binding growth factor-7), may be implicated in kidney cyst formation and expansion. However, there are no data on KGF expression in human autosomal dominant polycystic kidney disease (ADPKD) tissue, and it is unknown...

Immune reconstitution inflammatory syndrome (IRIS) in HIV-1-infected patients is associated with an exaggerated inflammatory response against an opportunistic infection during highly active antiretroviral therapy. The only review on IRIS associated with Criptococcus neoformans reported 21 episodes including lymphadenitis, necrotizing pneumonitis, breast and cutaneous abscess, and cryptococcomas...

background & objectives: odontogenic cysts are among the most frequent destructive lesions of jaws which their pathogenesis and growth mechanism are not cleared. with respect to different roles of mast cells, they may play a role in the pathogenesis and growth of odontogenic cysts. the aim of present study was to evaluate mast cells in the most common odontogenic cyst. methods: thirty  para...
