We hypothesized that the spread of SARS-CoV-2 in urine during a severe COVID-19 infection may be the expression of the worsening disease evolution. Therefore, the aim of this study was to verify if the COVID-19 disease severity is related to the viral presence in urine samples. We evaluated the clinical evolution in acute COVID-19 patients admitted in the sub-intensive care and intensive care units between 28 of December 2020 and 15th of February 2021 and being positive for SARS-CoV-2 RNA in the respiratory tract, including repeated endotracheal aspirates (ETA), sputum, nasopharyngeal swabs (NPS) and urine. We found that those subjects with SARS-COV-2 in the urine at admittance (8 out of 60 eligible patients) had a more severe disease than those with negative SARS-CoV-2 in urine. Further, they showed an increase in fibrinogen and (C-reactive Protein) CRP serum levels, requiring mechanic ventilation. Of those with positive SARS-CoV-2 in the urine, 50% died. According to our preliminary results, it seems that the presence of SARS-CoV-2 in the urine characterizes patients with a more severe disease and is also related to a higher death rate.

The presence of a high number of positive SARS-CoV-2 patients is found daily in the emergency room database, finding evidence of infection also in trauma and burns. Surgical debridement remains the gold standard for eschar removal, but it does not come without complications such as bleeding and high heat loss. In recent years, there has been an increase in the use of enzymatic debridement techniques, replacing surgical escharotomy. Early eschar removal is proven to be important; it has been proved that an early and effective burn treatment in COVID-19 patients can reduce other infection. Five clinical cases of patients arrived at our COVID-19 Major Burns Intensive Care Unit. On admission, burns extension and depth were assessed by an expert burn surgeon. We evaluated eschar removal modality, adverse events, and potential side effects. Enzymatic debridement was efficient in all patients treated with complete eschar removal, and no serious adverse events. All patients were treated within 24 hours of arrival at our facility with Nexobrid by specialized personnel in deep sedation and with O 2 support using a face mask or nasal goggles. The use of enzymatic debridement in COVID-19-positive burn patients within dedicated pathways through nonsurgical treatment optimizes the treatment time. We believe that the use of enzymatic debridement could be a valid therapeutic option in burn patients, even with SARS-CoV-2 infection, and its use, when indicated, is safe and effective for the patient and optimizes the use of instrumental and human resources in a pandemic emergency.

Bone marrow edema syndrome is a severely disabling painful condition without a defined treatment and related to pathogenetic mechanisms not yet clearly recognized. We report the case of a 59-year-old post-menopausal woman, affected by bone marrow edema associated with early osteonecrosis of the femoral head with secondary appearance of a rare migrant bone edema of the hip acetabulum. Clinical evaluation and magnetic resonance imaging were used to monitor the outcome of the patient. Pre-treatment clinical evaluation revealed pain upon stepping with the left limb, reduced range of motion of spine and hip, and hip pain during passive rotation. Magnetic resonance imaging showed diffuse signal alteration of the head and neck of the left femur in relation to bone edema, associated with an unclear small cephalic area of the femoral head suggestive of initial osteonecrosis. A further computed tomography scan was performed that did not reveal any alterations in bone profile, interruption of the cortex, or trabecular bone collapse. We immediately started a multimodal conservative treatment administering neridronate (100 mg, intravenously) combined with calcium and vitamin D supplementation and biophysical therapies (magnetotherapy and extracorporeal shockwave therapy). We also instructed the patient not to bear the load on the affected lower limb during standing and walking, using crutches. After 2 months, a notable regression of pain with improvement in mobility was observed. Magnetic resonance imaging revealed complete regression of edema at the head and neck of the femur; however, the new appearance of acetabular bone edema of the ipsilateral acetabular roof was detected. After 4 months, a third magnetic resonance imaging showed the disappearance of the femoral head and acetabular roof defects as well as the complete clinical recovery of the patient. An early diagnosis and intervention are essential to conservatively treat cases of bone marrow edema syndrome.

Pain harms the clinical course of individuals with rib fractures. Patients with more than three fractured ribs are more likely to have lung problems because pain can impede lung ventilation and secretion clearance due to difficulty coughing, resulting in atelectasis and hypoxia. Systemic analgesia to invasive regional anesthesia procedures such as thoracic epidural, paravertebral catheters, intercostal nerve blocks, and fascial plane blocks are all alternatives for analgesia in chest trauma. The study’s goal is to evaluate the analgesic efficacy of erector spinae plane (ESP) and serratus anterior plane (SAP) blocks in chest injuries, as well as their effect on improving respiratory metrics. For this objective, fifteen cases of isolated thoracic trauma resulting in rib fractures were reviewed retrospectively. All patients were at least 18 years old, spontaneously breathing, and had received a chest wall fascial plane block for pain relief. All patients reported practically instantaneous pain alleviation, with the onset occurring around 10 minutes after the block operation. One patient required oxygen therapy, but the rest were quickly weaned due to improved respiratory mechanics. Our findings suggest that chest wall anesthetic blocks are a safe and effective therapy for pain caused by rib fractures. At admission, the median NRS was 7 (RF 6:26.7%; 7:26.7%; 8:26.7%; 9:13.3%; 10:6.7%), with a minimum of 6 and a maximum of 10 (IQR: 1.5, CV: 0.2). All patients reported immediate pain relief that began around 10 minutes after the block was done; the average decrease in NRS was 6.8 points. They have also been shown to be effective and beneficial in improving respiratory parameters and lowering oxygen support.
