Simple Bone Cyst of the Mandible: Report of Two Cases
M. Imanimoghaddam,A. Javadian Langaroody,S. Nemati,S. Ataei Azimi
Iranian Journal of Radiology , 2011,
Abstract: Despite their names, simple bone cysts are no longer categorized as cysts since they lack an"nepithelial lining. However, their nature remains controversial. The internal structure is totally"nradiolucent, sometimes showing multilocular appearance, although the lesion does not contain"ntrue septa and the ridges of bone is produced by the scalloping effect. We presented two cases"nof histopathologically confirmed simple bone cyst. Radiographic features such as multilocular"nappearance and significant buccal and lingual expansion are not usual findings for simple bone"ncyst, whereas evident in our presented cases.
MULTIFOCAL ELECTRORETINOGRAPHY IN THE ASSESSMENT OF EYES WITH CENTRAL RETINAL VEIN OCCLUSION
M. S. Farahvash,S. Mohammadzadeh,A. Javadian,A. Mirshahi
Acta Medica Iranica , 2007,
Abstract: "nData suggest that the multifocal electroretinography (mfERG) may have a role in the assessment of patients with central retinal vein occlusion (CRVO). To explore the mfERG responses in patients with CRVO. mfERG responses were recorded at 61 discrete retinal locations from both eyes of 25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. The latencies and amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to fixation, and grouped central and peripheral rings of involved eyes were compared with values obtained from 13 normal fellow eyes of these subjects. The mfERG responses obtained from eyes with CRVO were significantly different from those derived from the fellow eye, especially when the rings are grouped as central and peripheral. mfERG is a new, safe, non-invasive, and quick investigative tool to assess retinal function. Our results suggest that mfERG could be a useful electrophysiologic test in clinical evaluation and determination of the severity of underlying ischemia in patients with retinal vein occlusion. Further studies are needed to evaluate its role as a prognostic method to determine which eyes are prone to serious complications. This is the first report of mfERG results in Iran.

S. Saidi,R. Tesh,E. Javadian,A. Nadim
Iranian Journal of Public Health , 1976,
Abstract: A total of 698 blood and serum specimens from residents of 13 Iranian communities were examined by plaque reduction neutralization test for antibodies to West Nile virus. In general, infection rates in the north of the country were low while higher rates were observed among residents of central and southwestern Iran. The highest prevalence of infection was found among residents of Khuzestan province, indicating that this region is one of endemic West Nile virus activity. The symptoms of west Nile virus infection in man are also discussed.
Evaluation of Serum Levels of Essential Trace Elements in Patients with Pulmonary Tuberculosis Before and After Treatment by Age and Gender
F. Pourfallah,S. Javadian,Z. Zamani,R. Saghiri
Pakistan Journal of Biological Sciences , 2011,
Abstract: The purpose of this study was to evaluate the levels of Zinc, Copper, Iron and Copper/Zinc ratio in the serum of adult patients with pulmonary tuberculosis in Iran. Serum levels of Zinc and Copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an Auto Analyzer. The study group consisted of 50 pulmonary tuberculosis patients before treatment and after 6 months of anti-tubercular therapy. Levels of serum Zn (p<0.001) and Fe (p<0.001) in TB patients were significantly increased after 6 months of anti-tubercular therapy. However, serum Cu concentration (p<0.01) and Cu/Zn ratio (p<0.05) were decreased after 6 months of anti-tubercular therapy. Some studies indicated a strong association of Zn, Cu, Fe and the Cu/Zn ratio with TB. In this study, we found remarkable change in Cu/Zn ratio. Some researchers mentioned that serum Cu/Zn ratio could be used as an important laboratory marker for diagnosis and treatment of tuberculosis. They also mentioned that trace element levels must be closely monitored during the process of disease.

Iranian Journal of Arthropod-Borne Diseases , 2009,
Abstract: "nBackground: The purpose of this study was to evaluate the levels of zinc (Zn), copper (Cu), iron (Fe) and zinc/ cop-per ratio in the serum of patients with cutaneous leishmaniasis in Qom Province, center of Iran."nMethods: Serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an Auto Analyzer. The study group consisted of 60 patients with cutaneous leishmaniasis and the control group of 100 healthy volunteers from the same area who were not exposed to cutane-ous leishmaniasis."nResult: There were no statistically significant differences in age and body mass index between the two groups. Se-rum Zn (P< 0.001) and Fe (P< 0.05) levels were lower in patients with cutaneous leishmaniasis than the control group. We also found serum Cu concentration (P< 0.05) in the patient group was significantly higher than that of the control group. However, zinc/ copper ratio (P< 0.001) was lower in patients with cutaneous leishmaniasis than in the control group."nConclusion: Our data indicated that Zn/Cu ratio was significantly lower in patients with CL as compared to the con-trols. Earlier reports suggest that, this ratio imbalance could be a useful marker for immune dysfunction in leishma-niasis. There was also strong association of Zn, Cu and Fe with CL. It suggests the use of blood zinc, copper, iron concentration and the copper/zinc ratio (Zn/Cu), as a means for estimating the prognosis of CL. Keywords: Cutaneous leishmaniasis, Zn, Cu, Fe.

Giant papillary conjunctivitis: A study of 700 cases
Javadian A
Tehran University Medical Journal , 1995,
Abstract: In view of the rapid expansion of contact lens amongst the users, new dimensions have been added to the domain of ophthalmology: Giant papillay conjunctivitis, a disease caused by different kinds of contact lens, appears weeks or months after they are used, although some patients are struck years later. The predominant symptoms are increased awareness of lenses, ocular itching, blurred vision and excessive lens movement. The predominant signs are the formation of papillae, the presence of excessive mucus, and contact lens coatings. The syndrome occurs mostly with the soft lens and is more intense. Other independent studies show that the rate of prevalence of the disease with soft lenses and hard lenses is 10% and 5% respectively. The study comprised 550 soft lenses and 150 hard lenses. The diagnosis of the disease was based on the symptoms and signs of the disease. Eleven percent of the patients using soft lens and 4% of the patients using hard lens had the disease at some stage. Almost all of the patients were using dirty and low grade lenses. The therapy protocol of the disease consisted of changing the polymer type of the lens and administering cromolyn 4% drop. In cases that the therapy was unsuccessful, a temporary suspension of the lens and administration of cromolyn 4% was recommended before using the new lens.

Khoshdel, A.;Alborzi, A.;Rosouli, M.;Taheri, E.;Kiany, S.;Javadian, M.H.;
Brazilian Journal of Infectious Diseases , 2009, DOI: 10.1590/S1413-86702009000100010
Abstract: visceral leishmaniasis remains a serious public health problem in developing countries. cytokines have a crucial role in the pathogenesis of this disease. we evaluated plasma levels of il-10, il-12 and ifn- in 32 patients with active visceral lieshmaniasis, in 29 siblings of the patients and in 23 normal individuals in an endemic area to look for correlations between the clinical outcome of infection and the plasma cytokine levels. an analysis was made with a skin test and a quantitative sandwich enzyme immunoassay. data were analyzed with the mann whitney test and the kruskal wallis test. the cytokine levels were significantly higher in the patients than in the control groups. we concluded that normalization of the plasma level of ifn- can serve as a reliable parameter for considering the patient as cured.
THE DISTRIBUTION AND PREVALENCE OF HUMAN INFECTION WITH PHLEBOTOMUS FEVER GROUP VIRUSES IN IRAN
R. Tesh. S. Saidi,E. Javadian,A. Nadim,M.A. Seedi-Rashti
Iranian Journal of Public Health , 1976,
Abstract: A total of 1,497 serum and blood specimens from residents of 18 different Iranian communities were examined by plaque reduction neutralization test for antibodies against four (Neaples, Sicilian, Karimabad and Salehabad) Phlebotomus fever virus serotypes. Neutralizing antibodies against the Naples and Sicilian serotypes were found in every community sampled, indicating that these viruses are widely distributed in the country. In contrast, Karimabad antibodies were restricted mainly to residents of Isfahan, Tehran and Khorassan Provinces. No evidence of human infection with Salehabad virus was found. Results of this study indicate that the frequency of human infection with Phlebotomus fever viruses is high in Iran. The symptoms of sand fly fever are also reviewed.

S.H. Hoseini Zarch,A. Bagherpour,A. Javadian Langaroodi,A. Ahmadian Yazdi
Iranian Journal of Radiology , 2011,
Abstract: Background/Objective: Panoramic radiography has a great place among imaging techniques because of its enormous advantages. One of the characteristics of an ideal imaging technique is to supply precise measurement. The purpose of the current study was to evaluate the accuracy of linear measurements of the jaws on panoramic radiographs.Patients and Methods: In this study, the vertical distances between the metal markers were measured by panoramic radiography in seven sites of two skulls in various head positions. Then the radiographic measurements were compared with the actual values.Results: Eighty three percent of the measurements were underestimated, 8.5% were overestimated on panoramic radiography and 8.5% of the measurements had no difference with the real measurements. Overestimation was not greater than 1 mm. The difference between actual and radiographic measurements was less in the posterior areas and in the mandible . In all head positions, the greatest difference between actual and radiographic measurements occurred in the anterior area.Conclusion: Based on the results of this study, linear measurements on panoramic radiography are more reliable in the posterior areas and may be used in early clinical measurements.
