SARS-CoV-2 infection in two patients following recent lung transplantation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) has become a global health problem with pandemic character. Lung transplant recipients may be particularly at risk due to the high degree of immunosuppression and the lung being the organ primarily affected by COVID-19. We describe a 16-year-old male and a 64-year-old female recently lung transplanted patients with COVID-19 during inpatient rehabilitation. Both patients were receiving triple immunosuppressive therapy and had no signs of allograft dysfunction. Both patients had close contact with a person who developed COVID-19 and were tested positive for SARS-CoV-2. Subsequently, both patients underwent systematic screening and SARS-CoV-2 was ultimately detected. Although the 16-year-old boy was completely asymptomatic, the 64-year-old woman developed only mild COVID-19. Immunosuppressive therapy was unchanged and no experimental treatment was initiated. No signs of graft involvement or dysfunction were noticed. In conclusion, our report of patients with asymptomatic SARS-CoV-2 infection and mild COVID-19, respectively, may indicate that lung transplant recipients are not per se at risk for severe COVID-19. Further observations and controlled trials are urgently needed to study SARS-CoV-2 infection in lung transplant recipients.

[Functional outcome of arthroscopic rotator cuff repair]. / Artroszkópos rotátorköpeny-rekonstrukció prospektív vizsgálata.

INTRODUCTION: Functional outcome after rotator cuff reconstruction is influenced by several factors of which re-rupture is probably the most important. AIM: The aim of the study was to evaluate the postoperative outcome including re-rupture rate after arthroscopic rotator cuff reconstruction. METHOD: 23 shoulders of 22 patients were examined prospectively. Physical examination, ultrasound and radiography were performed. Quality of life and functional outcome were evaluated using Constant Score and Visual Analog Scale. RESULTS: Excellent or good results were found in 80% of the patients. The Constant Score has increased from 45 to 79, and the level of pain decreased from 6.6 to 2.5. Full-thickness rotator cuff tear was absent, but partial tear occurred in 7 cases (30%). Average acromiohumeral distance in the operated side was 8.5 mm compared to 9.5 mm measured on the contralateral shoulder. CONCLUSIONS: Arthroscopic rotator cuff repair is a safe and reliable procedure that provides good results.

UNLABELLED: Rotator cuff tear is a common degenerative shoulder disorder that often requires surgical treatment. However, the correlation between the size of the tear and the functional results is somewhat controversial, which generates inconsistency among orthopaedic surgeons about the indications for and methods of rotator cuff reconstruction. AIMS: The aim of the authors was to evaluate the midterm functional outcome after rotator cuff reconstruction and the possible connection between the results and the surgical technique or the postoperative ultrasound examination. In addition, recently published corresponding studies are also reviewed by the authors. METHODS: Twenty-seven patients with full thickness rotator cuff tear were enrolled into the study who were treated either by arthroscopic (14 patients) or by open repair (13 patients) technique. Functional results were assessed using clinical tests. Ultrasound examination was also performed. RESULTS: The average postoperative Constant Score was 73, the average DASH (Disabilities of the arm, shoulder and hand score) was 14. The Constant scores averaged 80 for the arthroscopic and 70 for the open group. Ultrasound examination showed partial or full thickness retear of the cuff in 40% of the cases. CONCLUSION: More than 70% of the patients had excellent or good results two years after the reconstruction. The change in the acromiohumeral distance or partial retear failed to affect the results significantly, but full thickness tear had an effect on them.
