An extremely rare disease with a slow course, actinomycosis has a high mortality risk when not properly treated. Pulmonary actinomycosis is clinically and radiologically analogous with tuberculosis, foreign body aspiration, lung abscess, or lung cancer. Therefore, it often causes misdiagnosis or delay in diagnosis. ⋯ A diagnosis of actinomycosis was made with sulfur granules seen in the pathology as a result of biopsy and lavage. Detection of sulfur granules in biopsy is essential for the diagnosis of actinomycosis, and a nearly complete response is usually obtained with long-term antibiotic treatment. Alternative methods such as surgical debridement should be considered in cases that do not respond to antibiotic treatment.

Because of there is no sufficient evidence showing a relationship between blood types and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, this study was planned to investigate the effects of ABO blood group on the clinical outcomes of SARS-CoV-2 infection. ⋯ Our results are in agreement with other studies suggesting that blood group O individuals are somewhat more resistant to clinically overt infection with SARS-CoV-2 than other blood groups. In addition, Rh negativity may also be an individual risk factor for SARS-CoV-2 infection.

Radiation-related caries is a complex destructive lesion leading to uncompromising damage of enamel and dentin in patients suffering from head and neck cancer managed with radiotherapy. ⋯ Though radiation exposure did not alter the enamel permeability and surface topography, it had caused significant chemical compositional changes. Carbon content was significantly reduced in irradiated enamel samples.

The optimal treatment for distal tibial fractures remains a matter of debate. Nonetheless, plate osteosynthesis produces favorable results to intramedullary stabilization in aspects of alignment restoration. ⋯ Plate osteosynthesis for SWF or CF of the distal tibial metadiaphysis led to high union rates and good clinical outcomes. There was no significant difference in the radiologic and clinical results according to the presence of fracture comminution. Nonetheless, the valgus union group showed better clinical outcomes than the varus union group. Clinically, it would be preferred to avoid intraoperative varus reduction.

Polymerization plays an important role in the optical and mechanical properties resin composite materials. ⋯ Under the conditions of 10,000 thermal cycles, different curing times did not affect the color change and hardness values of the bulk-fill materials. However, differences were observed among the composite materials. After thermocycling, the surface hardness and TP values decreased in all the resin composites. Depending on the material content, effective results can be obtained from the 20 s polymerization of bulk-fill resin composites.
