Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome virus coronavirus 2 (SARS-CoV-2). E2 As known, COVID-19 has become a global pandemic and serious health problem. Disease mainly affects lungs and common findings are fever cough and shortness of breath. Computerized tomography (CT) has an important role in initial evaluation and follow up of COVID-19. Main (CT) finding of the disease is bilateral extensive ground-glass opacification (GGO) with a peripheral or posterior distribution, mainly involving the lower lobes. In this case report, we present a pneumothorax and subcutaneous emphysema case in a patient with COVID-19. To the best of authors' knowledge, it is the first illustrated case of pneumothorax accompanying COVID-19 pneumonia.Understanding the general rules of microbial interactions is central for advancing microbial ecology. Recent studies show that interaction range, interaction strength, and community context determine bacterial interactions and the coexistence and evolution of bacteria. We highlight how these factors could contribute to a general understanding of bacterial interactions.Background Sub-Saharan Africa shares a disproportionately large ratio of the global acute disease burden, however epidemiological data specific to the burden of emergency conditions are lacking. This study aimed to determine the morbidity burden of emergency conditions in Jimma city, Southwest Ethiopia. Methods A cross-sectional study was conducted using emergency case registries of three years from 2014 to 2017, at Jimma Medical Center and Shenen Gibe Hospital. 39,537 emergency visits were included in the study. The data were exported to SPSS V.23.0 for statistical analysis, descriptive analysis was used to summarize demographic characteristics, causes of visit, and morbidity rates. Findings were integrated with population-based health demographic reports quantifying the morbidity burden. Outcome measures were overall number of emergency visits and morbidity rates for the population groups. Results From a total of 39,537 visits, those between 15 and 29 years of age accounted for 42.1% (n = 16615), and 50.6% (n = 20004) were females. Communicable, Maternal, Neonatal and Nutritional (CMNNs) conditions accounted for 57.2%(n = 22597), followed by injuries (22.9%, n = 9055). Top five conditions were non-specific trauma (2.3%, n = 4861), complicated labor (8.4%, n = 3320), lower respiratory infections (8.1%, n = 3213), acute febrile illness (6.6%, n = 2600), and neonatal infections (3.7%, n = 1444). Conclusion The burden of acute conditions presented to public hospitals in Jimma city is high. Traumatic injuries, obstetric emergencies, lower respiratory infections, and neonatal emergencies were the most frequent causes of acute visits. An appropriate emergency care system that addresses this high burden of acute emergencies should be established in the study area.We investigated pneumococcal carriage between children ≦5 years old with otitis media (OM) and those without. Non-PCV13 serotypes were common in both groups; 19A remained the second most common serotype among children with OM despite high PCV13 coverage. This is important when considering a schedule with reduced vaccine doses or reduced valency, and the modification of pneumococcal immunization schedule should be followed up closely to monitor the result of protection against pneumococcal infections.Background Burn injuries are a major cause of morbidity and mortality worldwide. Despite advances in therapeutic strategies for the management of patients with severe burns, the sequelae are pathophysiologically profound, up to the systemic and metabolic levels. Management of patients with a severe burn injury is a long-term, complex process, with treatment dependent on the degree and location of the burn and total body surface area (TBSA) affected. In adverse conditions with limited resources, efficient triage, stabilisation, and rapid transfer to a specialised intensive care burn centre is necessary to provide optimal outcomes. This initial lag time and the form of primary treatment initiated, from injury to specialist care, is crucial for the burn patient. This study aims to investigate the efficacy of a novel visco-elastic burn dressing with a proprietary bio-stimulatory marine mineral complex (MXC) as a primary care treatment to initiate a healthy healing process prior to specialist care. Methods A new vings, this EBD + MXC is ideal for use in all pre-hospital, pre-surgical and resource limited settings.Background External radiotherapy has become indispensable in oncological therapies. Unfortunately, radiation is responsible for serious side effects, such as radiodermatitis. The skin is weakened and ulcerated. Our study aimed to evaluate the subcutaneous transfer of microfat (MF) alone and two mixes MF+Platelet-rich plasma (PRP) and MF+stromal vascular fraction (SVF) to treat radiation-induced skin lesions. Method We defined randomly five experimental groups of nine mice 1 healthy control group and 4 irradiated (60 Grey) and treated groups. The skin lesions were treated 3 months after irradiation by MF, MF+PRP (50%-50%), MF+SVF (90%-10%) or Ringer-lactate subcutaneous injections. Wound healing was evaluated at 1, 2 and 3 months post-injection and histological wound analysis at 3 months, after euthanasia. Results All the irradiated mice presented with wounds. After sham-injection, the wound area increased by 91.1±71.1% versus a decrease of 15.9±23.1% after MF alone (NS), 27.3±23.8% after MF+SVF (NS) and 76.4±7.7% after MF+PRP (P=0.032). A significative reduction of skin thickness in wound periphery was measured for the three treated groups compared to sham-injection (P less then 0.05) but not in the healed wounds (NS). The most important subcutaneous neo-vessel density was shown after MF+SVF injection. Conclusion The MF+PRP mix was the most efficient product to increase healing. The MF+SVF mix showed the highest rate of neo-angiogenesis but was disappointing in terms of healing. Level of evidence Not gradable.Background Optimal characterization of Adult acquired flatfoot deformity (AAFD) on two-dimensional radiograph can be challenging. Weightbearing Cone Beam CT (CBCT) may improve characterization of the three-dimensional (3D) structural details of such dynamic deformity. We compared and validated AAFD measurements between weightbearing radiograph and weightbearing CBCT images. Methods 20 patients (20 feet, right/left 15/5, male/female 12/8, mean age 52.2) with clinical diagnosis of flexible AAFD were prospectively recruited and underwent weightbearing dorsoplantar (DP) and lateral radiograph as well as weightbearing CBCT. Two foot and ankle surgeons performed AAFD measurements at parasagittal and axial planes (lateral and DP radiographs, respectively). Intra- and Inter-observer reliabilities were calculated by Intraclass correlation (ICC) and Cohen's kappa. Mean values of weightbearing radiograph and weightbearing CBCT measurements were also compared. Results Except for medial-cuneiform-first-metatarsal-angle, adequate intra-observer reliability (range0.
