Fibrous Hamartoma of Infancy, Report of Two Cases
Nona Zabolinejad,Mehran Hiradfar,Ahmad Bazrafshan
Iranian Journal of Pediatrics , 2008,
Abstract: Objective: Fibrous hamartoma of infancy (FHI) is a rare, benign soft tissue tumor that typically occurs within the first two years of life. It has a specific histologic appearance comprising of three different mesenchymal tissues with variable proportions in an organoid fashion. The clinical course is typically benign with excellent prognosis. We report two cases of this rare lesion and review its cilinicopathologic characteristics. Case(s) Presentation: The first case was a 15-month-old girl who had a subcutaneous mass in the right axillary region and the other one was an 18-month-old boy with a mass on the medial surface of his right ankle. The masses were successfully excised. After 6 and 30 months follow up no recurrence occurred. Conclusion: Although the clinical and imaging findings of FHI are quite similar to those of malignant soft tissue tumor, histologic characteristics of this tumor will guide to the definite diagnosis that will prevent aggressive and mutilating procedures.
Acute appendicitis after blunt abdominal trauma

Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Appendecitis is one of the most frequent surgeries. Inflammation of appendix may be due to variable causes such as fecalit, hypertrophy of Peyer’s plaques, seeds of fruits and parasites. In this study we presented an uncommon type of appendicitis which occurred after abdominal blunt trauma. In this article three children present who involved acute appendicitis after blunt abdominal trauma. These patients were 2 boys (5 and 6-year-old) and one girl (8-year-old) who after blunt abdominal trauma admitted to the hospital with abdominal pain and symptoms of acute abdomen and appendectomy had been done for them.Trauma can induce intramural hematoma at appendix process and may cause appendicitis. Therefore, physicians should be aware of appendicitis after blunt abdominal trauma
Multiple Congenital Epulis of the Mandibular Ridge: A Case Report
Mehran Hiradfar,Nona Zabolinejad,Mohammad Gharavi,Sadaf Sebt
Iranian Journal of Otorhinolaryngology , 2011,
Abstract: Congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. It occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. Although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter congenital epulis cells are negative for S-100 protein. This case report describes a 15-day-old female infant with multiple congenital epulis of the mandibular alveolar ridge.
Heterotopic Oral Gastrointestinal Cyst: Report of Two Cases
Nona Zabolinejad,Mehran Hiradfar,Ehsan Khadivi,Mohammad Gharavi
Iranian Journal of Otorhinolaryngology , 2010,
Abstract: Introduction: Heterotopic gastrointestinal cyst of the oral cavity is an extremely rare lesion with fewer than 40 cases reported in the English literature. It usually involves the soft tissue covering the floor of the mouth and the tongue. Lining of this lesion resembles gastric or intestinal mucosa. Case Report: In this report we describe the lesion in two boys and discuss their pathogenesis.
Definition of Success Rate of Appendectomy without Peritoneal Lavage in Children with Generalized Appendicular Peritonitis
Mehdi Fathi,Marjan Joudi,Mehran Hiradfar,Mohammad Mehdi Kamyar
Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: Peritonitis can be managed through local restoration, debridement during operation, lavage and a number of post-operative techniques such as drainage, continuous peritoneal lavage and re-operation in order to remove infective agents from the abdominal cavity as a way to prevent persistent peritonitis and sepsis. In this study, the results and complications caused by appendectomy without [diagnostic] peritoneal lavage in children with appendicular peritonitis were dealt with. Materials and Methods: A number of 30 children with the generalized peritonitis, a complication of perforated appendicitis, were studied. Fifty mg/kg ceftriaxone, 30 mg/kg metronidazole and sedatives were prescribed for all patients. Surgeries were performed by a single surgeon through making a small transverse incision in the right lower quadrant of the abdomen which included appendectomy and removing purulent discharges and debris collected around appendix without conducting peritoneal lavage. After surgery, the patients were examined in terms of incidence of complications, any more surgeries and treatment success for 6 weeks.Results: Five patients developed wound infection and three patients developed abdominal abscess. No early obstruction after surgery was seen. Peritonitis in all patients was controlled with appendectomy and antibiotic therapy and relaparotomy was not practiced for any patient. Conclusion: With regard to simplicity and high speed of appendectomy without cleansing peritoneum and its shorter incision and similar complications with other studies, and its considerable success to control the disease progress and unnecessary relaparotomy for the patients used this method, it seems that this method can be a good substitution for the conventional method of making long incision at midline of the abdomen and cleansing peritoneum.
Physiographic-Tectonic Zoning of Iran’s Sedimentary Basins  [PDF]
Mehran Arian
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.33020
Abstract:

Base on geological history evaluation using regional stratigraphy, sedimentary environments, magmatic activities, metamorphism and structural trend in Iran, physiographic-tectonic zoning map of Iran’s sedimentary basins has prepared. This map has prepared to point out the basement tectonics role in Iran. It contains twenty-four different provinces. Iran has composed from different plates: Arabian plate in south and west, Cimmerian manipulated in north and east, Eurasian plate in northeast margin. Cimmerian manipulated at least can be divided to the smaller part, East-Central Iran and North-Central Iran microcontinents. There are evidences for thick-skinned tectonics in the border zones of these plates and microcontinents, especially in Sanandaj-Sirjan overthrust belts that it formed by crustal stacking wedges. Also, Neoproterozoic-Phanerozoic Tectonic column in the Arabian, Cimmerian and Eurasian plates under Iran Country area have introduced.

Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.51004
Abstract:

The main purpose of the present study is to compare the perception of recalling pleasant and unpleasant face pictures in the case of depressed and manic people. Methodology: The present study is an analysis based on a comparative type research; the statistical sample is made up of depressed and manic people (males) referred to LAVASANI Hospital in Tehran City using Beck’s depression questionnaire and a diagnostic interview based on (SCID) DSMIV 30 depressed individuals who were selected after the process of screening. Ranging from moderate to high depression levels (with a cut-off point of 21 and higher), samples of 30 people with manic and 30 depressed people were compared with 30 healthy individuals. It should be mentioned that three groups were convergent in terms of age, gender, marital status and educational level. Then, a test involving computer-based cognitive-neural recall (emotional facial Pictures) was carried out on the related subjects. Findings: A t test of both independent groups was used to evaluate the convergence of the groups and multi variable bilateral variance analysis (MANOVA) was used to assess the pleasant and unpleasant perception of images among three groups. The results of the study showed that there is a difference among three groups in terms of recalling pleasant and unpleasant faces so that the depressed group shows a higher level of recall in terms of unpleasant images than the other two groups, but it indicates little recall of pleasant images in comparison to the other two groups (p < 0/05). Conclusion: The findings of the present study include some explicit outcomes in relation to the application of therapeutic approaches and concentrated educational methods on the amendment of emotional bias in depressed and manic people.

Mehran Arian, Hamideh Noroozpour
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.52005
Abstract: One of the most interesting salt structures is salt-tongue canopy. The Central Iran basin has a few salt provinces and in this paper, morphotectonic concept of the salt-tongue canopy on the west of Garmsar city has been investigated. In this study, field data coupling with the salt tectonic-related factors to provide a position for salt rocks in the west Garmsar. Firstly, various geological factors such as faults, folds and roads were extracted and compiled. This is because the factors mentioned above play important role in the instability of the region. The results of this study showed that the salt extrusion from the Lower Red formation is severe. Further, it is evident that the shortening of main structures has had a great impact on it whilst the salt movements have occurred within Garmsar Syncline. Finally, the paper concluded that the salt-tongue canopy in the region has increased the rates of salt extrusion.

Mehran Arian, Reza Nouri
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.53011
Abstract: The study area that is part of Tarom volcano-plutonic zone which host many hydrothermal base metal deposits located in Zanjan, NW Iran. Understanding the tectonic events that can cause mineralization and hydrothermal alteration are significant factor in assessing the exploration potential of different structures. In this research, hydrothermal alteration such as Iron oxide, argillic, phyllic, and propylitic zones were determined by Spectral Angle Method (SAM) and also lineaments identified by high pass filters and hill-shade DEM techniques on Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) data. Field studies revealed most alteration and mineralization occurred in NE-SW fractures and control mineralization.
Tectonic Geomorphology of Iran’s Salt Structures  [PDF]
Mehran Arian, Hamideh Noroozpour
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.52006
Abstract: Iran has a various salt structures that their tectonic geomorphology is subject of this paper. Geologic situation of salt structures in Iran have determinate. According to age and geological setting of salt deposits that revealed by tectonic geomorphology methods, salt structure provinces of the Central and Southern Iran have been distinguished. Also, critical concepts of salt diapirism in the Southern Iran and Central Iran salt basins have explained. Therefore, Central Iran’s salt diapirs have triggered by tectonic forces, but salt diapirism in the Southern Iran has triggered by halokinesis, then it has effected by tectonic forces, especially in Zagros fold and thrust belt.
