Head & Face Medicine , 2012, DOI: 10.1186/1746-160x-8-17
Abstract: This study was a prospective cohort study. Surgical techniques included using Medpor? in reconstruction of lamina papiracea (LP) (15 patients), frontal bone (15 patients), orbital rim (18 patients) and open rhinoplasty (8 patients). All interventions on LP were performed by endoscopic procedures. All frontal operations were carried out by bicoronal incision. In orbital defects, we used subciliary incision.From all 56 patients, 1 case had primitive neuroectodermal tumor (PNET) of maxillary sinus. In that case, reconstruction of inferior orbital rim was not successful and extrusion was occurred after radiotherapy. In rhinoplasty and other experiences no extrusion or infection were detected within the next 1 to 3?years of follow up. There were not any palpable and visible irregularities under the skin in our experiences.In this study the patients did not experience any complications during the follow up periods and the satisfaction was remarkable. Gathering these data gives rise to future review studies which can provide more organized evidences for replacing classic reconstructive methods by the presented material.Loss of tissue caused by trauma, cancer or surgery usually needs some materials for reconstruction. Initial methods which used human tissues as reconstructive materials caused different problems including disable to shape the graft, limitation of accessibility and donor site morbidity [1-3].In 1828, using artificial materials was established by using gold in nose reconstruction [1,4].Using silicon rubber, polyamide and Gore-Tex has been improved since 1950, but each of them was accompanied by different reactions such as extrusion, infection and not well-shaped slippery reconstruction [4-9].In 1970s porous high-density polyethylene (PHDPE, Medpor?) was introduced by its exclusive advantageous including no donor site morbidity, easily shaped and the minimal foreign body reaction [10-13]. Furthermore the likelihood of infection was reduced by significant vascul

BMC Medical Imaging , 2012, DOI: 10.1186/1471-2342-12-2
Abstract: The cross-sectional imaging study was conducted at Rasole Akram Hospital, Tehran, Iran. A total of 44 patients underwent X-ray computed tomography (CT) scanning; the presence of air in the esophagus and visible on CT imaging was scrutinized.The average age of the subjects was 59 and the male to female ratio was 0.83. We found a significant relationship between the presence of GERD symptoms, the size of air bubbles and esophageal dilation (ED) on the CT scan.Air bubbles in the esophagus may be seen frequently in CT scans, but their size and location can vary. The GERD symptoms can arise when a small diameter air column is present within the esophagus, especially in the middle and lower parts.Gastroesophageal Reflux Disease (GERD) is disruptive and places a great clinical and economic burden on patients and society as a whole [1]. A recent study estimated that 20% of the adult US population experience GERD-related symptoms at least once a week [2]. The disease is sometimes accompanied by extraluminal symptoms such as chronic cough, laryngitis, asthma and sinusitis [3]. GERD is one of the most common diseases that can be treated in many of those patients who suffer from it [4].Air is usually seen in radiological exams of the normal esophagus, but the extent and distribution of air has not been well described, and there is a paucity of data [5]. Previously Proto showed air seen in 36% of normal chest radiograph and then in a study [6] reported that an air column is visible in 64% of CT scans of the normal esophagus. Bhalla and Silver [7] defined esophageal dilatation (ED) as an air column greater than 10 mm in the coronal plane. Ponce revealed that increase in esophageal diameter in is associated with greater disease evolution [8]. Halber have showed that air in the esophagus is a normal finding [9]. However, data to confirm these findings are scarce.Therefore, the aim of this study is to identify and explore any relationships between GERD symptoms in the patients' hist

Infectious Agents and Cancer , 2012, DOI: 10.1186/1750-9378-7-10
Abstract: The samples were taken from 55 patients with benign laryngeal lesions and frozen in ?20°C. One milliliter (ml) of lysis buffer was added to 100 mg (mg) of each sample and the tube was placed in 56°C overnight. Then DNA extraction was carried out.To find HP DNA, in-house PCR was performed that revealed 5 positive results among 55 patients with benign laryngeal lesions. Of them, 3 were polyp, 1 was nodule and 1 was papilloma.Although the number of positive results was not a lot in this study, it was in contrast with previous studies which could not find any HP tracks in benign laryngeal lesions by other methods. More studies about the prevalence of HP in benign laryngeal lesions improve judging about the effect of this infection on benign laryngeal lesions.

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2018, DOI: 10.4236/jcdsa.2018.82011
Abstract: Background: Hair loss at the nape of the neck causes embarrassment and psychological stress in a number of patients due to a variety of causes including acne keloidalis nuchae and traction alopecia. Objectives: To report a case of hair transplantation into the nape of the neck as a treatment option for scarring resulting from acne keloidalis nuchae. Methods: 700 grafts where transplanted from the occipital donor area and transplanted by follicular unit extraction (FUE) into the nape area of a male patient with recurrent scarring folliculitis in that area. Results: Hair Restoration was successful with natural looking results. More tumescence than usual and skin traction was necessary to stabilize the skin during graft insertion due to soft skin in the nape area. Conclusions: Hair Restoration Surgery into the nape of the neck is an option for patients with hair loss in that area. FUE is the best method of hair transplantation allowing the selection of 1 and 2 hair FUE grafts in order to achieve a natural looking result in the nape area.

International Journal of English Linguistics , 2012, DOI: 10.5539/ijel.v2n3p10
Abstract: English as an international language emphasizes on learning different major dialect forms; in particular, it aims to equip students with the linguistic tools to communicate internationally. English is no longer merely used by native speakers but by all those who come to use it. The study reported in this paper was conducted in the population of Iranian students in the academic context of Malaysia who have learned English as a foreign language in their home country, but after immigrating to the multi lingual country of Malaysia have to use it as an International language to communicate not only with the academician but also with the common people. This shift of English language application had led them to a confusion, which reveals in in their performance, although they are not quite aware of the involving reasons. Therefore, this study examined this mismatch between EFL and EIL oral performance from the angle of hesitation, and investigated the hesitation strategies Iranian university students use while they are speaking English. It focused on the frequency and distribution of pauses, pauses and fillers, and fillers in the speech of 12 Persian speakers of English, students in a public university in Kuala Lumpur, Malaysia, participating in an oral test consisting of three parts to study whether the type of questions affect the hesitation strategies they employ or not. The data collected was collected and analyzed qualitatively and quantitatively, and the results indicated that Persian speakers of English follow different pausing conventions which varied by the change in the context of the questions.

International Journal of English Linguistics , 2012, DOI: 10.5539/ijel.v2n1p231
Abstract: This study attempted to find the relationship between providing Persian equivalents of English adjectives and Iranian EFL learners' active vocabulary. To this end, 100 students studying English as a foreign language at a Language Institute in Shiraz were asked to participate in this study. Participants were divided into experimental and control groups with 50 participants in each. The sample was homogenous with regard to their English level. To investigate the possible effects of providing Persian equivalents of English adjectives on Iranian EFL learners' active vocabulary, an independent Sample t-test was run on the vocabulary scores of 100 students. After analyzing the data it was found out the performances of all the participants in the “Experimental” group were better than those in the “Control” group.
Distribution of Hesitation Discourse Markers Used by Iranian EFL Learners during an Oral L2 Test
Shadi Khojastehrad
International Education Studies , 2012, DOI: 10.5539/ies.v5n4p179
Abstract: Previous studies on hesitation strategies used by beginner or advanced L2 learners revealed that beginners mostly leave their hesitation pauses unfilled which causes their speech to sound disfluent, and advanced learners tend to use various fillers in order to sound like native speakers. The present paper reports on a study which investigated the distribution of hesitation discourse markers including silent pauses, silent pauses and fillers, fillers, and non-lexical words used by Iranian university students in an oral (L2) test. The study examines the location of the discourse markers of hesitation across utterances produced by the participants. The respondents were a group of students registered in the Tertiary English Language Program at a university in Kuala Lumpur, Malaysia. The aim was to identify the frequency of all hesitation strategies used in four locations of Initial, Middle, and Final position of the utterances to find out the most frequent location of hesitation during an oral (L2) test.
