Frequency of craniofacial pain in patients with ischemic heart disease

Referred craniofacial pain of cardiac origin might be the only symptom of ischemic heart accidents. This study aimed to determine the frequency of craniofacial pain in patients with ischemic heart disease. This cross-sectional study was accomplished on 296 patients who met the criteria of having ischemic heart disease. Data regarding demographics, medical history and referred craniofacial pain were recorded in data forms. In addition, patients underwent oral examination to preclude any source of dental origin. Chi-square test, Student’s t-test and backward regression model were used to analyze the data by means of SPSS software version 21. P<0.05 was considered significant. A total of 296 patients were studied comprising of 211 men (71%) and 85 women (29%) with the mean age of 55.8. Craniofacial pain was experienced by 53 patients out of 296, 35 (66%) of whom were male and 18 (34%) were female. None of the patients experienced craniofacial pain solely. The most common sites of craniofacial pain were occipital and posterior neck (52.8%), head (43.3%), throat and anterior neck (41.5%) respectively. We found no relationship between craniofacial pain of cardiac origin with age, diabetes, hypertension, and family history. On the other hand, there was a significant relationship between hyperlipidemia and smoking with craniofacial pain of cardiac origin. Radiating pain to face and head can be expected quite commonly during a cardiac ischemic event. Dental practitioners should be thoroughly aware of this symptomatology to prevent misdirected dental treatment and delay of medical care

Pemphigus Disease: A geoepidemiologic preliminary study in Iran

Objectives Pemphigus is an autoimmune, life-threatening, blistering disease. Knowledge about the epidemiology of this disease however, is still limited. The aim of this study was to investigate the frequency and geographic distribution of pemphigus patients in Iran.Methods Medical records of patients with definitive diagnosis of pemphigus disease during a seven-year period from March 2006 to March 2013 were retrospectively reviewed. All individuals were classified based on geographical aspects.Results A total of 110 patients (59 females and 51 males) with an average age of 46.5 ± 13.6 for the females and 45.8± 12.5 for the males were evaluated. Male patients were slightly younger than female patients, but the difference was not statistically significant. Also, there was no significant association between age and the year of frequency. The most frequent type of pemphigus was the vulgaris type (93.6%). On the base of climate, the highest frequency was seen in the Moderate to severe internal (very hot) desert area and the humid and temperate climates (Caspian). There was no significant difference between the mean ages of pemphigus patients in the four geographic regions, (P value=0.421). Based on altitude in each climatic region, less than 10% of patients were from high altitude areas.Conclusion Environmental factors are important in frequency of autoimmune disease including pemphigus.  We concluded that the frequency of pemphigus disease might be different in different climates and altitude. Further research towards the improvement of data on the geographical study could open up a field to identify the patterns of pemphigus diseas

Removal of an Extra-large Irritation Fibroma With a Combination of Diode Laser and Scalpel

Introduction: Irritation fibroma is the most common tumor like and sub mucosal reactive lesion in the oral cavity. Usually it is measured less than 1.5 cm in diameter; however in rare case it has more than 3 cm in diameter. Different kind of treatment for soft tissue lesions include scalpel excision, electrical surgery, and laser surgery. The diode laser can be more effective than conventional surgery, electrosurgery and cryosurgery in reduction of bleeding and pain.Case Report: We reported a very large irritation fibroma in right lingual side of retromolar pad which was less prone to be traumatized under local irritation, in a woman wearing maxillary complete denture and use of both diode laser and scalpel for its excision

Quality of the Results Section of Original Dental Articles Published in National Farsi and International English Journals

Objective: Lack of scientific writing skills is one major problem encountered for publication of research results of Iranian scientists in accredited journals. As the result, many research projects or dissertation findings remain unpublished. This study aimed to assess the quality of writing of the “results” section of some original articles published in Iranian Farsi and international English journals.Methods: This analytical, cross-sectional study was conducted on 64 dental articles published in 3 international English and 3 Iranian Farsi journals. Selection of journals was non-random but articles were selected randomly based on specific criteria. A checklist containing 32 criteria regarding general statistics, context of the results, statistical tests, tables, charts and graphs was prepared. Obtained data were analyzed by SPSS 10 using Fisher’s exact and chi square tests.Results: Farsi articles met 64.1% and English articles met 65.8% of the checklist criteria. No significant difference was found in the quality of the results section of Farsi and English papers (p&gt;0.05).Conclusion: Most papers did not provide adequate details in the results section to help readers better comprehend the subject

Excision of different oral benign exophitic lesions with diode laser: A clinical Case Series

Introduction: Lasers are becoming the standard of care for many dental procedures, and are being introduced as a high-tech instrument. They are also becoming more routine in dentistry through the advent of office-based lasers, which are also simple to use within the oral cavity. Many studies have shown the competencies of laser technology for the management of benign oral lesions as these techniques allow for painless and bloodless oral surgery.Cases Report:&nbsp;Nine patients attending the Department of oral and maxillofacial Disease, Shahid Beheshti University of Medical Sciences, Tehran, Iran, underwent laser outpatient procedures for the surgical removal of a wide range of benign oral lesions. Regarding the history, present illnesses and clinical figures of all reported cases, the clinician ensured that the lesions were benign and after taking informed consent from every patient, he did complete the excision of lesions with diode lasers. Following the injection of local anesthesia, an 810 nm diode laser was applied for the excisional biopsy of oral lesions. The specimens were sent for histopathological evaluations and the patients were assessed on intraoperative and postoperative complications. The patients were followed up for postoperative complications at one week and 2 weeks post-treatment.Conclusions: According to our findings, a diode laser can be a choice for the outpatient treatment of oral mucosal benign lesions as this technique provides the painless and almost bloodless treatment

Oro-facial manifestations of 100 leprosy patients

Objectives: To verify the frequency of oral and facial involvement in diagnosed leprosy patients. Study design: This study was performed on 100 leprosy patients (62 male, 38 female, mean ages 51.86±6.1). After explaining the study design, we studied descriptive information including: patient?s sex, age, job, place of birth, familial history of leprosy, types of disease (lepromatous, borderline and tuberculoid leprosy), ocular and oral lesions, facial involvement and neuropathy. The statistical signification was measured by chi-square test. Results: A total of 46 (23 lepromatous, 15 borderline, and 8 tuberculoid leproy) out of 100 patients with leprosy had oral lesions. Statistical analysis did not show any significant difference in frequency of oral lesions between different types of disease. Facial lesions were presented in 57 (39 lepromatous, 10 borderline, and 8 tuberculoid leprosy) patients. There was a statistical significant difference in frequency of facial manifestations between different types of leprosy. It has to be mentioned that, atrophy of nasal spine, facial nerve involvement, ocular lesions and facial deformity were seen in 15%, 17%, 22% and 44% of leprosy patients, respectively. Conclusion: Examination of leprosy patients should be extended to the oral mucosa because oral mucosa may be a secondary source of M.Leprae transmission and infectio

Analysis of heavy metal accumulation and environmental indicators in fluids and drilling cuttings

Abstract Heavy metal pollution caused by oil well drilling operations is one of the environmental problems that the oil industry imposes on the environment. The source of such pollution should first be determined precisely to manage and control it. Studies show that the main source of environmental pollution in well drilling operations is the drilling fluid additives or the elements in the well column formations. In this research, in addition to measuring the concentration of heavy metals and comparing it with the existing standards, an attempt is made to determine the exact origin of these metals. To study the source of such pollution in the area of the Abteymour oil field in the southwest of Iran, 19 cuttings (from 8 formations), 10 waste samples (drilling mud and cutting), and 7 drilling muds and their additive samples from one of the wells were assessed to determine the concentration of heavy metals. In this study, a total of 56 elements were measured using the ICP-MS analysis method; however, 16 elements that had a higher concentration than the average of the upper crust (as a reference concentration) with Ni, Cr, and V elements were studied. These 16 elements included Fe, Ag, As, Ba, Bi, Cd, Cu, Mg, Mn, Mo, Pb, Sb, Sr, and W heavy metals, and Ca and S elements. The analysis of the examined elements' concentrations in muds and their additives revealed that samples of heavy water-based muds and barite contained the highest concentrations of the elements. The cuttings samples primarily had a higher concentration than the waste samples, which was due to the mixing of the cuttings of different depths in the waste and the dilution of the element concentration in the waste samples, according to an analysis of the variation of 19 elements compared to the depth. Among the studied formations, the Gachsaran Evaporite Formation has high concentrations of studied elements. This problem is due to the complexity of the lithology of Gachsaran Formation, which consists of all kinds of rocks such as anhydrite, gypsum, salt and marl. This result shows the importance of managing drilling operations in this formation to prevent the release of heavy metals in the environment. Based on the Igeo, Ca, Ag, As, Ba, Bi, Cd, Cu, S, Sb, and Sr elements had high levels of pollution in all samples of waste and drilling cuttings. Based on the EF, only Cr, Mn, and V elements had no enrichment, and other elements had different enrichment levels in waste and drilling cuttings samples. The main result of this study shows that the main source of heavy metal pollution in the first stage is the type of elements in the lithology of the well column formations and in the next stage is the type and additives of the drilling fluid used in the well. Specifically, in the Abteymour oil field, the main reason for the contamination of the Gachsaran formation is due to the complexity of the lithology and the use of heavy water base drilling mud. The results of this research show that before choosing the type of drilling fluid, it is necessary to do a detailed environmental study and identify heavy elements in subsurface formations and the designed drilling fluid

Quality of the materials and methods section of original dental research articles published in the iranian and international journals

Background and Objectives: Lack of scientific writing skills is believed to be a major obstacle in the course of research publication and dissemination by the Iranian researchers. Without following the globally accepted publication standards, dissertations, and projects cannot reach their final goal of being published and incorporated into practice. We aimed to compare the writing quality of a number of dental original articles written in Farsi and published in the Iranian journals with those written in English and published in international journals. Materials and Methods: In this analytical cross-sectional study, we selected 64 articles from six dental journals (three international English journals and three Farsi journals) by simple random sampling method. A list of 48 variables covering the study design, sampling method, subject allocation, ethical issues, interventions, measurements, and statistical methods was used to evaluate each article. The results were analyzed using Chi-square or Fisher's exact test. Results: Our results demonstrated that Farsi articles (n = 32) fulfilled 61.1% of our checklist criteria while English articles (n = 32) achieved a score of 59.1%, with no statistically significant difference (P > 0.05). Conclusion: We believe that the selected articles successfully reported most of the necessary elements. Their main shortcoming seemed to be the lack of clarification of details
