Co-infection of SARS-CoV-2 with Chlamydia or Mycoplasma pneumoniae: a case series and review of the literature.

INTRODUCTION: The novel coronavirus SARS-CoV-2 has spread all over the world causing a global pandemic and representing a great medical challenge. Nowadays, there is limited knowledge on the rate of co-infections with other respiratory pathogens, with viral co-infection being the most representative agents. Co-infection with Mycoplasma pneumoniae has been described both in adults and pediatrics whereas only two cases of Chlamydia pneumoniae have been reported in a large US study so far. METHODS: In the present report, we describe a series of seven patients where co-infection with C. pneumoniae (n = 5) or M. pneumoniae (n = 2) and SARS-CoV-2 was detected in a large teaching hospital in Rome. RESULTS AND CONCLUSION: An extensive review of the updated literature regarding the co-infection between SARS-CoV-2 and these atypical pathogens is also performed.

The treatment of thoracic and lumbar spine fractures: a study of 123 cases treated surgically in 101 patients.

For a total of 123 thoracolumbar traumatic lesions treated surgically in 101 patients over approximately 2 years (all monitored clinically and radiographically up to consolidation by follow-ups after from 6 to 26 months, mean 10 months) the technique used, complications and treatment are reported. The treatment procedure included: emergency surgery decompression, osteosynthesis, and fusion (posterior and possibly intersomatic); immediate recovery of function and loading; clinical and radiographic monitoring within 4-6 weeks, and possible anterior fusion in case of insufficient reconstruction of the anterior column. The complications observed out of 123 fractures were: collapse of the implant (4 cases), infection (5 cases), liquoral fistula (1 case), transitory paralysis of the abdominal muscles homolateral to the lombotomic incision (1 case), TVP (2 cases), bronchial pneumonia (2 cases), paralytic ileum (1 case). There was no sagittal deformity (secondary kyphosis) except for 5 cases of mechanical collapse that were resolved with a new operation. Neurologic deficit was caused by fracture in 49 patients (40% of the fractures or 48% of the patients). Six patients out of 30 affected with spinal cord lesion (20%) and 15 out of 19 affected with cone and/or cauda lesion (79%) improved. There was no progression of the neurologic findings after surgery. The authors conclude by proposing a protocol of posterior osteosynthesis for the use of a system in titanium made up of pedicle screws and hooks connected to a pair of cylindrical bars joined together.
