Acute dacryoadenitis in a patient with SARS-CoV-2 infection.

We describe a retrospective case report of dacryoadenitis associated with orbital inflammatory disease in a patient with confirmed SARS-CoV-2 infection.A 22-year-old previously fit and healthy male presented with 4-day history of right ocular redness, eyelid swelling and blurred vision associated with discomfort and pain in the lacrimal gland area. He was found to have right acute dacryoadenitis based on clinical examination and orbital imaging. One day after initiation of oral antibiotic and non-steroidal anti-inflammatory therapy, he developed worsening of the orbital inflammation and partial ophthalmoplegia. Oral steroids were commenced resulting in rapid resolution of symptoms within a few days and clinical stability at 2 months.The patient did not have any systemic features of COVID-19 but he was in close contact with his mother and with his partner who both had respiratory symptoms and tested positive for SARS-CoV-2 antigen (PCR testing) 4 weeks prior. PCR testing from nasopharyngeal swab was negative for SARS-CoV-2 RNA; however, the serological test was positive for IgM/IgG SARS-CoV-2 antibodies. Extensive laboratory workup including infectious and autoimmune screening and chest x-ray were unremarkable.Orbital inflammatory disease due to infectious process or immunological response may potentially occur in COVID-19 patients, although the causal relationship remains uncertain.

Design considerations of a randomized clinical trial on a cognitive behavioural intervention using communication and information technologies for managing chronic low back pain.

BACKGROUND: Psychological treatments have been successful in treating chronic low back pain (CLBP). However, the effect sizes are still modest and there is room for improvement. A way to progress is by enhancing treatment adherence and self-management using information and communication technologies (ICTs). Therefore, the objective of this study was to design a trial investigating the short- and long-term efficacy of cognitive behavioural treatment (CBT) for CLBP using or not ICTs. A secondary objective of this trial will be to evaluate the influence of relevant variables on treatment response. Possible barriers in the implementation of CBT with and without ICT will also be investigated. METHODS: A randomised controlled trial with 180 CLBP patients recruited from specialised care will be conducted. Participants will be randomly assigned to three conditions: Control group (CG), CBT, and CBT supported by ICTs (CBT + ICT). Participants belonging to the three conditions will receive a conventional rehabilitation program (back school). The CBT group program will last six sessions. The CBT + ICT group will use the internet and SMS to practice the therapeutic strategies between sessions and in the follow-ups at their homes. Primary outcome variables will be self-reported disability and pain intensity. Assessment will be carried out by blinded assessors in five moments: pre-treatment, post-treatment and 3-, 6-, and 12-month follow-ups. The influence of catastrophizing, fear-avoidance beliefs, anxiety and depression in response to treatment in the primary outcomes will also be analysed. DISCUSSION: This study will show data of the possible benefits of using ICTs in the improvement of CBT for treating CLBP. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01802671.
