Spontaneous plaque rupture visualized by intravascular ultrasound.
1994
An intravascular ultrasound examination was performed in order to evaluate an angiographically complicated lesion. Intravascular ultrasound was able to demonstrate spontaneous plaque rupture in a patient with recent acute subendocardial infarction. The inconclusive angiographic appearance was clarified by the intravascular examination and led us to conclude that the myocardial infarction was due to plaque rupture with subsequent thrombotic occlusion, which had spontaneously resolved by the time of the study.
Surgical nuances on the treatment of giant dumbbell cervical spine schwannomas: description of a challenging case and review of the literature
2016
We report a case of a giant intra and extradural cervical schwannoma in a patient affected by a severe myelo-radiculopathy. Clinical features, diagnosis and the issues concerning the surgical management of this benign tumor are discussed. We also review similar cases previously reported in the literature. A 50-year old caucasian woman was complaining of a 1 year of neck pain and worsening motor impairment in all four limbs causing the inability to walk. Neuroradiological assessment revealed a suspected schwannoma involving the nerve roots from C3 to C5, compressing and deviating the spinal cord. The vertebral artery was also encased within the lesion, but still patent. A posterior cervical …
Tissue characteristics in non-culprit lesions during the acute coronary event and at ten months follow-up
2013
Introduction: It is not well established how the medication recommended in the guidelines will affect plaque compositional changes in non-culprit segments after STEMI. We hypothesized that the proportion of necrotic tissue in the non-culprit lesion in the culprit artery would decrease ten months after STEMI. Methods: In 63 consecutive STEMI patients the non-culprit segment in the culprit artery was analyzed with iMap intravascular ultrasound (IVUS) at the time of the index procedure and 10 months later. The non-culprit segment was identified as being 20mm proximal to the most stenotic culprit segment. All patients were recommended to receive the drug therapy outlined in the STEMI guidelines…
Acute Nicotine Induces Anxiety and Disrupts Temporal Pattern Organization of Rat Exploratory Behavior in Hole-Board: A Potential Role for the Lateral…
2015
Nicotine is one of the most addictive drugs of abuse. Tobacco smoking is a major cause of many health problems, and is the first preventable cause of death worldwide. Several findings show that nicotine exerts significant aversive as well as the well-known rewarding motivational effects. Less certain is the anatomical substrate that mediates or enables nicotine aversion. Here, we show that acute nicotine induces anxiogenic-like effects in rats at the doses investigated (0.1, 0.5, and 1.0 mg/kg, i.p.), as measured by the hole-board apparatus and manifested in behaviors such as decreased rearing and head-dipping and increased grooming. No changes in locomotor behavior were observed at any of …
Comparative study of the efficacy of herbal antioxdants oxitard and aloe vera in the treatment of oral submucous fibrosis
2014
Objectives: Oral submucous fibrosis (OSMF) is a potentially malignant disorder predominantly seen in the Indian subcontinent due to areca nut, tobacco and their products. The aim of the present study was to compare the efficacy of oxitard and aloe vera in the management of OSMF. Material and Methods: 120 subjects with OSMF were included in the study. The patients were clinico-pathologically diagnosed and divided equally in 2 groups, Group A (oxitard group) and Group B (aloe vera group). Group A was administered 2 oxitard capsules twice daily and Group B was given 5 mg aloe vera gel to be applied topically thrice daily for 3 months. Different clinical parameters were evaluated at regular int…
Angina bullosa hemorrhagica, an uncommon oral disorder. Report of 4 cases
2020
Angina bullosa hemorrhagica (ABH) is a rare oral disorder characterized by blood-filled bullous lesions in the oral cavity and the oropharynx in the absence of an underlying systemic, haematological or mucocutaneous condition. The presentation of the lesions is acute and located on the lining mucosa, mainly on the soft palate. Often, these lesions are single and rupture easily leaving an ulcerated area. In this study, we present 4 ABH cases in 3 women and 1 man and we discuss the main clinicopathological characteristics. The characteristics of this disorder are important to recognize in order to differentiate the lesions from other oral bullous conditions of the oral cavity such as mucocuta…
Removal of fungal ball from the jaws by lefort i osteotomy: Difficulty in diagnosing patients with chronic sinusitis
2021
Aspergillosis, aka fungal ball (FB), is classified as a type of non-invasive fungal rhinosinusitis, which usually occurs unilaterally in the maxillary sinus of an immunocompromised patient. Its diagnosis is complex and depends on the association between clinical, imaging, and histopathological exams. There are many treatments for fungal infections of the paranasal sinuses, so early diagnosis is extremely important to determine the appropriate treatment. This paper reports an unusual clinical case of aspergillosis present bilaterally inside the maxillary sinuses of a healthy patient, associated with mucous retention cysts, whose imaging exams and transnasal endoscopy were not sufficient to p…
Aneurysmal bone cyst of the mandible with conservative surgical management : a case report
2019
The aneurysmal bone cyst is a nonneoplastic, osteolytic and locally destructive lesion that mainly affects the metaphyseal area of long bones and only 2% of it is diagnosed in the maxillofacial skeleton. Although surgical treatment is the most common option, it is associated to high morbidity rates. The case of an aneurysmal bone cyst of a considerable size in a 27-year-old male patient illustrating a conservative surgical approach with preservation of the dental structures in the mandible to limit aesthetic and functional side effects is presented. Two-year clinical follow-up was performed with no evidence of recurrence. Key words:Aneurysmal bone cyst; curettage, conservative treatment, ma…
Odontogenic Myxoma: Follow-Up of 13 cases after conservative surgical treatment and review of the literature
2021
Background We aim to report a serie of odontogenic myxoma over a 40-year period. Material and Methods We conducted a retrospective and sectional review of OM cases. The clinical, radiographic and treatment data were collected from clinical records included cases whose medical records contained clinical, radiographic, histopathological, follow-up data of at least six months. Results There was a mild preference for the male with a mean age of 22.8 years. Seventy-seven percent of the lesions occurred in the posterior region of the mandible, presenting a multilocular radiolucent aspect (54%) with one presenting symptomatology. Conservative treatment was performed in all patients initially and r…
Unusual microscopic changes of Ameloblastic Fibroma and Ameloblastic Fibro-odontoma : a systematic review
2019
Background Ameloblastic fibroma (AF) and ameloblastic fibro-odontoma (AFO) are uncommon benign mixed odontogenic neoplasms. Although unusual microscopic changes including hybrid tumors have been documented in publications, their clinical outcome prediction and treatment modality selection are still challenging due to scarcity. Objective: Analysis of AF/AFO's unusual microscopic variants in order to improve histopathologic diagnosis and to help clinicians in making informed treatment choices. Material and methods An electronic search was performed in PubMed's database using keywords: "ameloblastic fibroma", "ameloblastic fibroodontoma", "ameloblastic fibro-odontoma". The search scheme was li…
