A Rare Odontogenic Tumor Known as Cementoblastoma; A Case Report

Background: Odontogenic tumors are derived from the epithelial and/or mesenchymal remnants of the tooth-forming apparatus. Therefore, they are found exclusively in tooth-bearing areas. Similar to other neoplasms in the body, odontogenic tumors tend to histologically mimic the cell or tissue of origin. Case history: A 5-year-old boy presented with a chief complaint of pain in the mandible which started 3 months ago. Oral examination revealed bony expansion and a radiopaque mass fused with the roots of deciduous second molar was detected during radiographic examination. After surgical excision of the lesion and the involved tooth, microscopic examination revealed neoplastic tissue consisted of trabeculae of mineralized material with irregular lacunae and prominent basophilic reversal lines. Each trabecula was lined by prominent cells surrounded by cellular connective tissue. The lesion infiltrated the pulp chamber and root canals. Conclusions: According to the clinical and radiographic findings, bone-producing tumors, odontogenic tumors with calcifications and reactive lesions were included in the differential diagnosis. However, based on histopathology and radiographic data, final diagnosis of Cementoblastoma, a benign odontogenic tumor, was confirmed. Patient follow-up revealed no recurrence of the lesion

A STUDY ON RODENT ECTOPARASITES IN BANDAR ABBAS: THE MAIN ECONOMIC SOUTHERN SEAPORT OF IRAN

Rodents are one of the main health problems in the cities, especially in coastal area. These animals make economic damages and are potential health dangers in Bandar Abbas, the main economic southern port of Iran. In this study, rodents were captured from different parts of the city, before and after a control program during 2003-2004, transferred to the laboratory, identified and examined for ecto-parasites. Totally 105 rodents demonstrating four species: Rattus rattus   (3%), R. norvegicus (78%), Mus musculus   (3%) and Tatera indica   (16%), were captured before the control program. The most frequency was observed in Ayatollah Ghafari quarter, 10 rodents per 24 traps. After 12 months, the duration of control program, rodents were re-captured to assessment the success of control activity. In this stage 35 small mammals demonstrated four species were obtained: R.norvegicus (51.4%), R.rattus (37.1%), T.indica (8.6%) and one weasel (2.9%). We found the most frequency in Khoon-sorkh quarter with 6 rodents per 24 traps. The identified ectoparasites were Xenopsylla buxtoni   , Rhipicephalus sp., Polyplax gerbilli   , Haplopleura captiosa   , Ornithonyssus bacoti   , Laelaps nuttalli   , Dermanyssus americanus   , Dermanyssus sanguineus   , Haemolaelaps glasgowi   and Echinolaelaps echidninus   . The number of rodents reduced to one third after control program, shows the relative success of this program (p<0.05)

Bionomics of Anopheles stephensi Liston in the malarious area of Hormozgan province, southern Iran, 2002

Anopheles stephensi Liston is an important malaria vector in Hormozgan province, where it is the most prevalent anopheline mosquito. It shows two annual activity peaks, one in spring and another in the autumn. In mountainous areas the second peak starts earlier than in coastal regions. Adults are endophilic and endophagic, but in the hot season when people sleep outside buildings they frequently bite outdoors. Larvae are found in a wide-range of habitats, both natural and man-made. All three biological forms of the species, occur in the province, i.e. An. stephensi stephensi (type form), An. stephensi mysorensis, and the intermediate form. An. stephensi mysorensis is found only in rural-mountainous areas, whereas the type and intermediate forms occur in urban-coastal regions and the rural plains, with the type form predominant. The presence of the type form in urban areas and mysorensis in rural areas is consistent with the available epidemiological data for malaria in the region and with the finding in India that the type form is an efficient malaria vector inhabiting urban areas whereas mysorensis is rural and has a lower vectorial capacity. Insecticide susceptibility tests on field collected adult mysorensis and adults from laboratory strains of the type and intermediate forms were carried out according to WHO standard methods. These showed that all three forms are susceptible to bendiocarb, propoxur, malathion, fenitrothion, deltamethrin, permethrin, cyfluthrin, and lambdacyhalothrin, but are resistant to DDT and show low level of tolerance to dieldrin. Examination of the larvicidal activity of malathion, fenitrothion, temephos and chlorpyrifos at diagnostic doses showed that these stephensi forms are susceptible to all larvicides except fenitrothion. Irritability tests to pyrethroid insecticides showed high levels of irritability to permethrin and lambdacyhalothrin, but low irritability to cyfluthrin and deltamethrin. The importance of these findings for the epidemiology and control of malaria in the region are discussed. (c) 2005 Elsevier B.V. All rights reserved

Primary immune deficiencies presenting in adults: seven years of experience from Iran.

Primary immunodeficiencies (PIDs) are not solely diseases of childhood. We describe the clinical presentation and outcome for 55 adult patients with previously unrecognized PIDs. This series provides unique data regarding PIDs presenting in adulthood, and serves as a timely reminder that physicians must consider the diagnosis of PIDs in their adult patients. Using the experience gained from these patients, we outline key "warning signs" suggestive of an underlying PID. Only through increased physician awareness will patients with PIDs receive timely diagnosis and optimal management
