Kikuchi Fujimato Disease

Kikuchi Fujimato disease (KFD) also know as histiocytic necrotizing lymphadenitis (HNL) is a benign, self limiting disease, which commonly affects young women under 30 years of age. Most of the cases resolve in a six month period. Laboratory and clinical findings of KFD show similarities with tuberculosis lymphadenitis, mailgn lymphoma, other malign and benign diseases. The diagnosis is established on the basis of histology of lymph node excisional biopsy. The differentiation of KFD from Sistemik Lupus Eritematosus (SLE) can sometimes be problematic because both can show similar clinical and histological features. KFD and SLE can be seen together. Forty two years-old female patient diagnosed with KFD was discussed in light of current literature

An Evaluation of the Protective Effects of Thymoquinone on Amikacin-Induced Ototoxicity in Rats

ObjectivesIn this study we investigated the probable protective effects of thymoquinone on amikacin-induced ototoxicity in rats.MethodsThirty-two healthy rats were divided into four groups (amikacin, amikacin+thymoquinone, thymoquinone, and no treatment). Thymoquinone was fed to the rats via oral gavage in a dose of 40 mg/kg/day throughout the study period of 14 days. Amikacin was given by the intramuscular route in a dose of 600 mg/kg/day. Audiological assessment was conducted by the distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) tests, administered to all rats at the beginning of the study, and also on days 7 and 15. Biochemical parameters were calculated at the termination of the study to evaluate the oxidative status.ResultsThere were significant decreases in DPOAE values and significant increases in ABR thresholds of the amikacin group on days 7 and 15, as compared to the amikacin+thymoquinone group. While ABR thresholds of the amikacin group increased significantly on days 7 and 15 as compared to their initial values, there were no significant differences between the initial and the 7th and 15th day values of ABR thresholds in the amikacin+thymoquinone group. Total oxidant status and oxidative stress index values of the amikacin+thymoquinone group were significantly lower than those of the amikacin group. Total antioxidant status values of the amikacin+thymoquinone group were significantly higher than those of the amikacin group.ConclusionOur study has demonstrated that the ototoxic effect brought forth by amikacin could be overcome with the concurrent use of thymoquinone

Schwannoma Located in Nasopharyngeal Region

Schwannoma is a tumor which has neuroectoderm origins, is hard, well-circumscribed, encapsulated, and slow growing benign cranial tumor, and may autonomously grow out of the nerve sheath of peripheral nerves. It is mostly seen in the head and neck region. In the paranasal sinus and nose areas, it is seen at a rate of 4%. The diagnosis is mostly made after histopathological examination. In this paper, a Schwannoma case observed in the nasopharyngeal region was presented in a 20-year-old female who had complaints of sleeping with open mouth, snoring, foreign body feeling in throat, and swallowing difficulties. The tumor was extracted via transoral approach. No recurrence was observed during follow-up over the next year. This case presentation is presented for the first time in the literature in English

Effects of a thermosensitive in situ gel containing mometasone furoate on a rat allergic rhinitis model

WOS: 000432900700002PubMed ID: 29644886Background: Mometasone furoate, one of the second generation intranasal corticosteroids, is currently used in suspension form due to its poor solubility. However, this is not favorable for nasal application because of the rapid elimination of the instilled drug from the nasal cavity by mucociliary clearance and delayed onset of action due to the slow dissolution of drug in suspension. Objective: The aim of this study was to determine the antiallergic effects of mucoadhesive thermosensitive in situ gel containing mometasone furoate that we developed previously to prolong the contact between the drug and nasal mucosa and to prevent drainage of the formulation in an ovalbumin-induced rat model of allergic rhinitis. Methods: An experimental allergic rhinitis model was developed in female Wistar albino rats by intraperitoneal injection of ovalbumin every 2 days for 14 days followed by its repeated intranasal instillation for 7 consecutive days. Intranasal instillation of ovalbumin was continued every other day for 14 days. Mometasone furoate in situ gel (5 mu g/10 mu l), mometasone furoate suspension (5 mu g/10 mu l), and physiological saline (10 ml) were administered into the bilateral nasal cavities from day 22 to day 35. Antiallergic effects were evaluated through histopathological evaluation, analysis of ovalbumin-specific serum immunoglobulin E, and a symptom score. Results: Mometasone furoate in situ gel significantly decreased the nasal symptoms and ovalbumin-specific serum immunoglobulin E level as compared with mometasone furoate suspension and physiological saline. Additionally, inflammatory histological symptoms such as mucosal edema, vascular dilatation, eosinophil infiltration, and loss of cilia within the nasal mucosa of allergic rhinitis model rats were remarkably improved with the treatment of mometasone furoate in situ gel. Conclusion: These results suggest that mometasone furoate in situ gel has a better therapeutic potential for the treatment of allergic rhinitis compared to mometasone furoate suspension.Scientific Research Project Coordination Unit of Istanbul University [41584]; TUBITAK (The Scientific & Technological Research Council of Turkey) [114S820, 1002]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by Scientific Research Project Coordination Unit of Istanbul University (Project Number: 41584) and Rapid Support Program (1002) of TUBITAK (The Scientific & Technological Research Council of Turkey (Project Number: 114S820)

Angiofibroma Localized in the Sphenoid Sinus

Juvenile nasopharyngeal angiofibroma is the most common benign tumor of the nasopharynx with complaints of unilateral nasal obstruction and recurrent nosebleeds in the young male population. Despite being a benign tumor, it can be aggressively destructive in surrounding tissues and bones by acting locally. The gold standard treatment method is the surgical excision of the tumor. This case report is a case of angiofibroma, a 32-year-old asymptomatic male patient with no evidence of clinical signs and endoscopic examination, which is recognized as a localized vascular mass lesion in the right sphenoid sinus on the cranial MR imaging. We prepared this case report that may represent an angiofibroma localized only within the sphenoid sinus which is very rare in the literature
