Refractory Takayasu's Arteritis with Severe Coronary Involvement-Case Report and Literature Review.

This report presents the case of a female patient diagnosed with Takayasu arteritis from childhood, with severe, refractory coronary involvement, leading to two acute coronary syndromes and multiple anginous episodes. Consequently, the patient suffered aorto-bicarotid bypass two times, multiple interventional procedures with stent implantation, balloon angioplasty, and up to ten repeated in-stent restenosis that required reinterventions, despite being on maximal immunosuppressive treatment. In recent years, various studies have been reported that aim to best characterize this particular type of vascular damage and to indicate optimal therapeutic options for treatment. The latter should be based on the activity of the underlying disease; however, no reliable markers are available in TA. The management of TA patients with coronary involvement continues to be a challenge and requires both drug and interventional techniques to avoid life-threatening events.

Myopathic syndrome revealing a rare condition: Sheehan syndrome, a case-based review.

This report presents a case of a Sheehan syndrome diagnosed with a delay of 29 years after occurrence of first symptoms, following a laborious birth ended with dead fetus and massive hemorrhage. The 50-year-old patient, with early menopause from the age of 21, is referred to our rheumatology department to investigate the etiology of a myopathic syndrome, which started 2 months before and gradually worsened. The differential diagnosis took into consideration the autoimmune, infectious, paraneoplastic, endocrinological, and drug-induced myopathic syndrome. Paraclinical investigations revealed panhypopituitarism, and cerebral magnetic resonance imaging detected empty-sella. The etiology of a myopathic syndrome is often multifactorial; therefore, it is important to continue the investigations even after identifying one possible etiological factor, especially when it does not seem to fully explain the clinical-paraclinical picture. Usually, the multiple dimensions of panhypopituitarism bring the patient to various medical specialties depending on the dominant symptomatology. Given the rarity of the above-mentioned syndrome in the present, and the long gap between the initial event and the final diagnosis, its identification continues to be a challenge.

Evaluation of the outcome of various laser therapy applications in root canal disinfection: A systematic review.

BACKGROUND: Any successful endodontic therapy requires elimination of the endodontic biofilms through meticulous root canal disinfection methods. Sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) are the most common effective irrigants, in removing smear-layer from the coronal and middle thirds of the dental canals but reduced considerably towards the apical one third. In recent years, newly alternative treatment modalities have been proposed, including high-power lasers and antimicrobial photodynamic therapy (aPDT). Our work was conducted to evalaute the outcome of root canal disinfection in relation to the efficacy of various treatment modalities. Furthermore, every effort was made to present an overview of the aPDT outcomes, as a model for this application, and to propose laser parameters protocol with positive results. METHODS: The electronic databases PubMed was searched from January 2013- January 2019. Our inclusive criteria based on laser therapy applications, as a model for root canal disinfection. The search terms utilised various combinations as follows: photodynamic therapy or antimicrobial photodynamic therapy or photoactivated disinfection or light activated disinfection or laser activated disinfection or laser therapy, and endodontic. RESULTS: The results of this systematic review concluded that the effectiveness of aPDT and various laser wavelengths protocols, in removing endodontic biofilms from infected root canals, remains unattainable. CONCLUSIONS: Study concluded that the combination of aPDT with antimicrobial irrigants could provide a synergetic effect. However, due to the heterogeneity of the selected studies and their limitations, in terms of lack of standardised protocol or discrepancy in the methodology, authors suggest further validated approaches to achieve optimal outcomes.
