Aim is to assess the temporal changes and prognostic value of chest radiograph (CXR) in COVID-19 patients. Material and methods: We performed a retrospective study of confirmed COVID-19 patients presented to the emergency between March 07-17, 2020. Clinical & radiological findings were reviewed. Clinical outcomes were classified into critical & non-critical based on severity. Two independent radiologists graded frontal view CXRs into COVID-19 pneumonia category 1 (CoV-P1) with <4 zones and CoV-P2 with ≥4 zones involvement. Interobserver agreement of CoV-P category for the CXR preceding the clinical outcome was assessed using Kendall's τ coefficient. Association between CXR findings and clinical deterioration was calculated along with temporal changes of CXR findings with disease progression. Results: Sixty-two patients were evaluated for clinical features. 56 of these (total: 325 CXRs) were evaluated for radiological findings. Common patterns were progression from lower to upper zones, peripheral to diffuse involvement, & from ground glass opacities to consolidation. Consolidations starting peripherally were noted in 76%, 93% and 48% with critical outcomes, respectively. The interobserver agreement of the CoV-P category of CXRs in the critical and non-critical outcome groups were good and excellent, respectively (τ coefficient = 0.6 & 1.0). Significant association was observed between CoV-P2 and clinical deterioration into a critical status (χ2 = 27.7, p = 0.0001) with high sensitivity (95%) and specificity (71%) within a median interval time of 2 days (range: 0-4 days). Conclusion: Involvement of predominantly 4 or more zones on frontal chest radiograph can be used as predictive prognostic indicator of poorer outcome in COVID-19 patients.

Prostatic haematuria is among the most common genitourinary complaints of emergency room visits, distressing and troublesome to men and a challenging clinical problem to the treating physician. The most common aetiologies of prostatic haematuria include benign prostatic hyperplasia and prostate cancer. Prostatic haematuria usually resolves with conservative and medical methods; failure of these interventions results in refractory haematuria of prostatic origin (RHPO), a potentially life-threatening scenario. Several different treatments have been described, with varying degrees of success. Patients with RHPO are often elderly and unfit for radical surgery. Prostate artery embolization (PAE) has evolved as a safe and effective technique in the management of RHPO. Use of a superselective approach optimizes clinical success while minimizing complications. This minimally invasive approach improves patients with haemodynamic instability, serves as a bridge to elective surgery, and is a highly effective treatment for RHPO. It may obviate the need for more invasive and morbid surgical therapies. The aim of the present review was to describe the current management of RHPO and the technique of PAE and to review its efficacy and associated morbidity.

We have successfully revealed orbital vessels in retrobulbar space for the first time using MRA, by using the BORR pulse method. With a clear depiction of the vasculature without the need for contrast enhancement, our method has the potential to provide important diagnostic information for ocular vascular diseases.
