Effects of Early Physical Therapy and Follow-Up in Acute Severe Coronavirus Disease 2019 Pneumonia: A Retrospective Observational Study.

Background: Rehabilitation in subjects with severe coronavirus disease 2019 (COVID-19) pneumonia has been widely recommended. However, data regarding the starting time of rehabilitation, subjects and healthcare workers' safety, as well as rehabilitation program features are limited. We aimed to assess the safety and characterize the effect of early and non-early physiotherapy on severe COVID-19 pneumonia subjects.

A straightforward scanning electron microscopy technique for examining non-metal coated dental hard tissues.

Modifications to the standard operating settings for accelerating voltage, condenser lens current, scan rate, working distance and tilt on the conventional scanning electron microscope (SEM) enabled non-metal coated dental hard tissues and synthetic apatite pellets to be viewed free of charging effects. Well-resolved images at magnifications as high as 35,000x were achieved using accelerating voltages less than 5 kV. The methodology detailed here allowed for serial SEM examination of the same sample at various points during an experimental procedure, and may be applied to other sample types.

Treatment of chronic prostatitis: intraprostatic antibiotic injections under echography control.

We treated 51 patients diagnosed as having chronic bacterial prostatitis (gram-negative) with 2 ml. intraprostatic amikacin (500 mg.) or tobramycin (100 mg.
