    <p>Abstract</p> <p>Background</p> <p>Ectopic eruption of teeth in non-dental sites is a rare phenomenon and can present in a variety of ways such as chronic or recurrent sinusitis, sepsis, nasolacrimal duct obstruction, headaches, ostiomeatal complex disease and facial numbness. However, presentation of such patients with recurrent haemoptysis has not been described in the literature so far. We have described a case of an ectopic, supernumerary molar tooth in the maxillary antrum in a patient who initially presented with haemoptysis.</p> <p>Case presentation</p> <p>A 45-year-old male presented with a 2-month history of episodic haemoptysis. A pedunculated growth from the inferior nasal turbinate was seen with fibre-optic visualization. Although the patient was empirically started on antibiotic and anti-allergic therapy, there was no improvement after a few weeks and the patient had recurrent episodes of haemoptysis. Fibre-optic visualization was repeated showing bilateral osteomeatal erythema. Computed tomography scan of the paranasal sinuses demonstrated complete opacification of the left maxillary antrum along with a focal area of density comparable to bone. An ectopic, supernumerary molar tooth was found in the left maxillary antrum on endoscopic examination and subsequently removed. In addition, copious purulent discharge was seen. Post-operatively, the patient was treated with a 10-day course of oral amoxicillin-clavulanate. On follow-up, he reported resolution of symptoms.</p> <p>Conclusion</p> <p>Recurrent haemoptysis has not been described as a presentation for a supernumerary, ectopic tooth in literature before. We recommend that in patients with sinusitis-type of opacification of maxillary antrum and whose condition is refractory to conventional medical treatment, consideration should be given to the investigation of possible underlying anomalies as the cause of such symptoms. Presence of foreign bodies and ectopic teeth in paranasal sinuses can be reliably excluded with the use of appropriate radiological imaging and endoscopic examination.</p

    Using clickers in a large business class: examining use behavior and satisfaction

    YesAs more and more institutions are integrating new technologies (e.g., audience response systems such as clickers) into their teaching and learning systems, it is becoming increasingly necessary to have a detailed understanding of the underlying mechanisms of these advanced technologies and their outcomes on student learning perceptions. We proposed a conceptual model based on the technology acceptance model to understand students’ use behavior and satisfaction with clickers. The valid response from 138 second-year business students of Digital Marketing module taught in a British university, where clickers are extensively used in the teaching and learning process, made the basis for data analysis. The results provided a strong support for the proposed model with a reasonably adequate variance (i.e., adjusted R2) of 67% on behavioral intentions and sufficiently high variance on use behavior (i.e., 86%) and user satisfaction (i.e., 89%)

    Non-puerperal inversion of the uterus caused by leiomyosarcoma: A case report and clinical management

    No full text
    PubMedID: 17578377Uterine inversion is a rare complication of the postpartum period, but it is an even rarer complication of the non-puerperal period. A 49-year-old nulliparous woman was admitted to the hospital with the following complaints: abnormal vaginal bleeding, pain, anuria and a mass protruding from the vulva. The mass was removed by twisting and a laparotomy was required for massive bleeding due to the inversion. The diagnosis of complete inversion was made during the laparotomy. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed and the pathological examination revealed a leiomyosarcoma. Uterine inversion in the non-puerperal period is an extremely rare event and it should be kept in mind that the cause of the inversion may be a malignant disease, like leiomyosarcoma. © 2007 The Authors

    Heterogeneity in recurrent complete hydatidiform mole: Presentation of two new Turkish families with different genetic characteristics

    No full text
    PubMedID: 20870286Subsequent pregnancy outcomes following complete hydatidiform moles (CHM) are usually favorable and the risk of a second CHM less than 2%. However, a small number of women have a rare autosomal recessive condition that predisposes them to CHM. Unlike typical CHM, that are androgenetic (AnCHM), the CHM in these women are diploid and biparental (BiCHM) with a contribution from each parent to the nuclear genome. To date most women with recurrent CHM have been found to have BiCHM and to have a wide variety of mutations in the causative gene, NLRP7. Our objectives were to genotype the molar tissue and identify the NLRP7 mutations in two unrelated Turkish women with recurrent CHM. Fluorescent microsatellite genotyping of molar tissue and screening of patient DNA for NLRP7 mutations was carried out in two women with five and four CHM respectively. The first case was confirmed to have BiCHM. In addition the patient was found to have a novel homozygous mutation in exon 8 of NLRP7. All CHM examined in the second case were AnCHM and no NLRP7 mutations were identified in DNA from the patient. This report describes a further individual with BiCHM and a novel mutation in NLRP7. A second patient with similar clinical history had no mutations in NLRP7 and is the first report of a patient with four CHM where the CHM are androgenetic. This study highlights the heterogeneity of recurrent CHM and the need to investigate women with recurrent molar pregnancies for appropriate clinical management. © 2010 Elsevier Ltd.

    Characterization of phenolic compounds in sweet lime (Citrus limetta) peel and freshly squeezed juices by LC-DAD-ESI-MS/MS and their antioxidant activity

    Sweet lime (Citrus limetta) is one of the citrus species and it is generally consumed fresh or processed to fruit juice. The squeezing method of fruit is an important factor affecting the quantity and composition of phenolic compounds of the juice. The aim of this study was to identify and quantify the phenolic compounds and determine the antioxidant activities of sweet lime peel and juices. For this purpose, sweet lime juices were prepared using two different methods. Firstly, sweet lime fruits were hand-squeezed without peeling. Secondly, fruits were hand-squeezed after the manual removal of the peel. The phenolic compounds of the peel and the two types of juices were analyzed by LC-DAD-ESI-MS/MS. Twenty phenolic compounds were determined in all extracts, 18 of which were flavonoids and two were phenolic acids. The major compound was hesperidin both in the peel and juices. The procyanidin B dimer and luteolin were detected for the first time in sweet lime peel and juices in the present study. The amount of phenolic compounds of the peel was significantly higher than those of the juices. The total phenolic contents of the sweet lime juice increased about 13% from 444.55 to 502.54 mg/L due to the effect of the peel. The antioxidant capacity of the peel was found to be higher than those of the juices resulting from its high phenolic content. © 2019, Springer Science+Business Media, LLC, part of Springer Nature

    Prenatal diagnosis of giant left ventricular diverticulum: Case report

    No full text
    PubMedID: 25286772The distinction between a ventricular aneurysm and diverticulum is difficult. The differences between these two are based on anatomical, histological, and functional criteria. We present a case of prenatal diagnosis of a giant left ventricular outpouching at 28 weeks gestation. During the postnatal period, the neonate underwent surgical correction for the outpouching. Histopathological examination reported the resected segment was a cardiac diverticulum. Our case indicates that differentiating between the two diagnoses during the intrauterine period is not always straightforward and possible. Histopathological examinations are sometimes necessary to make a precise differentiation. Treatment should be individualized depending on the clinical presentation.
