Background There were no comparing data about the effect of recently developed file system OneCurve on apical debris extrusion. Aim The aim of this in vitro study was to compare the influence of the rotary nickel-titanium (Ni-Ti) files on apical debris extrusion after cervical preflaring. Materials and Methods Sixty-six lower incisor teeth with a…[Read more]

e US.DNA damage response (DDR) and repair pathways determine neoplastic cell transformation and therapeutic responses, as well as the aging process. Altered DDR functioning results in accumulation of unrepaired DNA damage, increased frequency of tumorigenic mutations, and premature aging. Recent evidence suggests that polypeptide hormones play a…[Read more]

Paracoccidioidomycosis is a dimorphic fungal infection endemic in Latin America. We report a patient with a history of pulmonary paracoccidioidomycosis who presented with relapsed disease in the central nervous system 4 years after initial treatment. We review current treatment strategies for paracoccidioidomycosis and neuroparacoccidioidomycosis.…[Read more]

Lexical matching between ICD-11 and ICD-10-CM identified 4059 pairs of possibly equivalent codes. Manual recoding showed that 60% of a sample of 388 ICD-10-CM codes could be fully represented in ICD-11 by precoordinated codes or postcoordination. CONCLUSION In ICD-11, there is a moderate increase in the number of codes over ICD-10. With…[Read more]

Medically unexplained physical symptoms (MUPS) is a common, yet neglected disease with a prevalence of around 25% in primary care setting. These patients present with multiple physical and psychological symptoms, without an underlying diagnosis, hampering their functional and mental wellbeing. The management of these undiagnosed symptoms through…[Read more]
