“…The specificity of LUS findings has been reported only by one study showing that in the presence of suggestive symptoms, the combination of apical consolidations and sub-pleural oval or round nodules, can reach a specificity of 96% [43]. There is agreement among authors that for TB, LUS has a poor ability to screen radiographically identified cavities [29,41,43].…”

The Role of Ultrasound in the Diagnosis of Pulmonary Infection Caused by Intracellular, Fungal Pathogens and Mycobacteria: A Systematic Review

Background: Lung ultrasound (LUS) is a widely available technique allowing rapid bedside detection of different respiratory disorders. Its reliability in the diagnosis of community-acquired lung infection has been confirmed. However, its usefulness in identifying infections caused by specific and less common pathogens (e.g., in immunocompromised patients) is still uncertain. Methods: This systematic review aimed to explore the most common LUS patterns in infections caused by intracellular, fungal pathogens or mycobacteria. Results: We included 17 studies, reporting a total of 274 patients with M. pneumoniae, 30 with fungal infection and 213 with pulmonary tuberculosis (TB). Most of the studies on M. pneumoniae in children found a specific LUS pattern, mainly consolidated areas associated with diffuse B lines. The typical LUS pattern in TB consisted of consolidation and small subpleural nodes. Only one study on fungal disease reported LUS specific patterns (e.g., indicating “halo sign” or “reverse halo sign”). Conclusions: Considering the preliminary data, LUS appears to be a promising point-of-care tool, showing patterns of atypical pneumonia and TB which seem different from patterns characterizing common bacterial infection. The role of LUS in the diagnosis of fungal disease is still at an early stage of exploration. Large trials to investigate sonography in these lung infections are granted.

Optimizing integrated imaging service delivery by tier in low-resource health systems

et al. 2021

Access to imaging diagnostics has been shown to result in accurate treatment, management, and optimal outcomes. Particularly in low-income and low-middle-income countries (LICs, LMICs), access is limited due to a lack of adequate resources. To achieve Sustainable Development Goal (SDG) 3, access to imaging services is critical at every tier of the health system. Optimizing imaging services in low-resource settings is best accomplished by prescriptive, integrated, and coordinated tiered service delivery that takes contextual factors into consideration. To our knowledge, this is the first recommendation for optimized, specific imaging care delivery by tier. A model for tier-based essential imaging services informs and guides policymakers as they set priorities and make budgetary decisions. In this paper, we recommend a framework for tiered imaging services essential to reduce the global burden of disease and attain universal health coverage (UHC). A lack of access to basic imaging services, even at the lowest tier of the health system, can no longer be justified by cost. Worldwide, affordable modalities of modern ultrasound and X-ray are becoming an accessible mainstay for the investigation of common conditions such as pregnancy, pneumonia, and fractures, and are safely performed and interpreted by qualified professionals. Finally, given the vast gap in access to imaging resources between LMICs and high-income countries (HICs), a scale-up of tiered imaging services in low-resource settings has the potential to reduce health disparities between, and within countries. As the access to appropriately integrated imaging services improves, UHC may be achieved.

A 1‐year‐old, male, neutered German shepherd dog was presented for a chronic atraumatic non‐healing fracture of the right accessory carpal bone, stranguria and polyuria/polydipsia. Biochemistry and urinalysis showed azotaemia. Ultrasound and computed tomography of the abdomen both demonstrated bilateral renal infarcts with pyelectasia, bilateral ureteral dilation and bladder distension. Cystoscopy of the bladder identified a fungal ball obstructing the pelvic urethral sphincter, which was adhered to the bladder mucosa in the region of the ureterovesicular junction. The obstruction was traversed endoscopically, but could not be removed transurethrally. The combination of elevated serum galactomannan titres (6.4) and Aspergillus terreus cultured from urine, confirmed a diagnosis of disseminated aspergillosis. The dog was euthanased due to poor quality of life, guarded prognosis and lengthy timeframe before an expected medical response. This is the first case report describing Aspergillus fungal balls in a dog causing partial urethral and bilateral ureteral obstruction, identified using cystoscopy.
