A Case Report of Differential Diagnosis of Causes of Severe Valvular Heart Disease (Takayasu's Arteritis, Infective Endocarditis and Myxomatous Degeneration) with the Key Role of Histological and PCR Examination

Aortic valve lesion is a common and may have diverse causes, from degenerative, congenital and infectious diseases to autoimmune conditions. We present a rare case of Takayasu arteritis and severe heart lesion due to the myxomatous degeneration of the aortic and mitral valves associated with development of infective endocarditis (IE) complicated by abscess, fistula, valve perforation and recurrent acute decompensated heart failure in a young female patient. A combined use of histopathological and PCR analyses of valve tissues was critically important for differential diagnosis of the valve lesions, as it made it possible to identify the true cause of the disease. The presence of Takayasu arteritis has played an indirect role by creating conditions for the development of immunosuppression and determining the disease severity and its progression

ON THE ISSUE OF THE PECULIARITIES OF SURGICAL TREATMENT OF VARIOUS HISTOLOGICAL VARIANTS OF AMELOBLASTOMA

The typical treatment of ameloblastoma is by surgery. The result of the procedure nevertheless  does  not always lead to complete healing of the sickness but to a recurrence during the post-operative period. It has been reported by a number of authors that the recurrence of the condition is influenced by a number of factors such as the kind of surgical intervention, the histological variant of the ameloblastoma and the incomplete removal of the tumor. The purpose of this research is to study the incidence of recurrence of ameloblastoma after surgery, taking into consideration type of surgery and size of the tumor. A study of 76 cases of ameloblastoma with different histological structures was undertaken in the laboratory of pathological anatomy of Central Research Institute of Dental and Maxillofacial Surgery. Data such as the recurrence of the disease and tumors size was collected, registered and analysed. The size of the tumors was expressed in conventional units. The analysis showed that basal cell and plexiform variants of ameloblastoma are often relate to cases with aggressive clinical courses. The tendency to the recurrence of the disease was also observed in the follicular and acanthomatous variants. According to the results of this study, cases of peripheral variants of ameloblastoma have the best prognosis
