[Treatment and outcome of malignant external auditory canal and middle ear tumor in Ghaem hospital - Mashhad]

External Auditory Canal and Middle Ear tumor are rare. Its unspecific symptoms make the physician confuse and has not a good prognosis. The aim of this study was to access the prevalence and comparing of middle and external ear carcinoma [Squamous Cell Carcinoma or Basal cell Carcinoma] in demographic factors and kind of management. In this cross sectional study we evaluated the patients with squamous cell carcinoma and basal cell carcinoma of external and middle ear who treated in ENT ward of Ghaem hospital Mashhad during 1995- 2009. We randomly selected 63 patients and followed them up for 2-24 months. Our findings showed that of total 47 patients with external auditory canal malignant tumors had either SCC [46.81%] or BCC [53.19%]. In the other hand of 16 patients with middle ear malignant tumor showed either SCC [93.75%] or BCC [6.25%]. Two- year survival in external auditory canal malignancies was much better than middle ear malignancies. The rates of recurrence in external auditory canal malignancy and in middle ear malignancy were 13% and 50% respectively. The best management in this malignancies is en block resection

[Determination of reservoir[s] and vector[s] of cutaneous leishmaniasis by nested-PCR in Marvdasht District, Fars Province, Southern Iran]

Cutaneous leishmaniasis [CL] is an increasing public health problem in several parts of Iran. In southern parts, the incidence of CL has been doubled over the last decade. This epidemiological study was done for determination of reservoir[s] and vector[s] of cutaneous leishmaniasis in rural regions of Marvdasht, Fars province, southern Iran during 2003 and 2004. A total of 126 rodents were collected from three villages using live traps and their Giemsa-stained smears were studied for leishmania infection. After DNA extraction from positive smears, Nested-PCR was used for the identification of parasite species. In another procedure, 200 sand flies were collected by aspirator and after species identification DNA extraction and PCR was done. The collected samples included Meriones libycus [75.4%], Cricetulus migratorius [14.3%] and Microtus arualis [10.3%]. Eight out of 95 Meriones libycus [8.4%] were found to be infected with Leishmania major. None of the other species were positive. Among the collected female sandflies 75% were identified to be Phlebotomus papatasi and 2.7% of them were found with L.major infection. Only 2.7% of Phlebotomus papatasi were found naturally infected with Leishmania major. This is the first report of detection of L.major by Nested-PCR in P.papatasi as a proven principal vector of zoonotic cutaneous leishmaniasis in Fars province, south of Iran

Ameloblastic odontoma

A case of odontoameloblastoma affecting the left maxilla that was treated by radical excision [removal of 2-3 mm of the unaffected bone] is reported. A permanent dental obturator was clasped onto the remaining teeth providing complete replacement of the excised hard palate and lost dentition. This permanent obturator will allow the patient to speak normally and eat all kinds of food three months after surgery
