Abstract
Background Cancer patients constitute one of the highest-risk patient groups during the COVID-19 pandemic. In this study, it was aimed to perform a systematic review and meta-analysis to determine both the incidence and ICU (Intensive Care Unit) admission rates and mortality in SARS-CoV-2 infected cancer patients. Methods The PRISMA guidelines were closely followed during the design, analysis, and reporting of this systematic review and meta-analysis. A comprehensive literature search was performed for the published papers in PubMed/Medline, Scopus, medRxiv, Embase, and Web of Science (WoS) databases. SARS-CoV-2 infection pooled incidence in the cancer populations and the risk ratio (RR) of ICU admission rates/mortality in cancer and non-cancer groups, with 95% confidence intervals (CIs), were calculated using the random-effects model. Results A total of 58 studies, involving 709,908 participants and 31,732 cancer patients, were included in this study. The incidence in cancer patients was calculated as 8% (95% CI: 8–9%). Analysis results showed that mortality and ICU admission rate was significantly higher in patients with cancer (RR = 2.26, 95% CI: 1.94–2.62, P < 0.001; RR = 1.45, 95% CI: 1.28–1.64, p < 0.001, respectively). Conclusion As a result, cancer was an important comorbidity and risk factor for all SARS-CoV-2 infected patients. This infection could result in severe and even fatal events in cancer patients. Cancer is associated with a poor prognosis in the COVID-19 pandemic. Cancer patients should be assessed more sensitively in the COVID-19 outbreak.

Abstract
A 44-year-old woman presented with sudden onset of chest pain, headache and nausea. Physical examination was remarkable for mild hypotension and tachycardia. ECG demonstrated sinus tachycardia with poor R wave progression in precordial leads and T wave inversion in leads V1-3. Cardiac enzymes were raised. Echocardiographic examination revealed normal cavity diameters with basal and mid left ventricular hypokinesia and an ejection fraction of 45%. A diagnosis of non-ST elevation myocardial infarction was made. A few orthostatic hypotensive attacks occurred at follow-up. A coronary angiogram showed normal coronary arteries. Within a few days, the echocardiographic findings, ECG and all cardiac markers had returned to normal. Two months later she presented with headache, palpitation, fever, neck swelling, flushing and hypertensive attacks. Phaeochromocytoma was diagnosed on the basis of increased metanephrine on urinalysis and a left suprarenal mass on CT scan.

Abstract
A 55-year-old male with structurally normal heart presented with sustained monomorphic ventricular tachycardia (VT) and was cardioverted into sinus rhythm revealing a right bundle branch block pattern at baseline electrocardiography. Sustained monomorphic and nonsustained polymorphic VT were reproducibly inducible during electrophysiological study. During the diagnostic workup, the patient experienced fever due to hospital based pneumonia, which unmasked typical ST segment changes of Brugada syndrome. In the intensive care unit, fever became intractable leading to incessant monomorphic VT, which was resistant to all medical manoeuvers resulting in the patient's death.

Abstract
This study was designed to assess color Doppler echocardiographic parameters in subjects with minimal mitral regurgitation (MR) in an otherwise normal heart. Study cases were selected during a five month period from 2500 young males with an echocardiographic indication on the basis of subjects' complaints and physical examination. Left ventriculography was performed and subjects were dichotomized into group-1 (n = 30) if there was angiographically MR and into group-2 (n = 30) if they were intact. Patients in group-1 were described as to have 'true MR' and MR flow in group-2 was named 'physiological'. Doppler echocardiographic variables of true and physiological MR are compared to each other. The following echocardiographic variables were significantly different between group-1 and group-2: 1) the ratio of the max. duration of MR/mean systolic interval in parasternal long axis (0.710 +/- 0.244 vs 0.430 +/- 0.268, respectively, p < 0.001), 2) the ratio of the maximum duration of MR/mean systolic interval in apical four chamber view (0.550 +/- 0.361 vs 0.317 +/- 0.272 respectively, p = 0.007), 3) the peak velocity of the regurgitant flow in parasternal log axis (180 +/- 77 vs 120 +/- 69, respectively, p = 0.003), 4) the regurgitant jet area in parasternal long axis (0.813 +/- 0.651 vs 0.411 +/- 0.431, respectively, p = 0.007). The maximal duration of MR/mean systolic time interval > or = 0.6, regurgitant jet area > or = 0.4 cm2, and regurgitant peak velocity > or = 130 cm/sec. in parasternal long axis dichotomize the cases into true with a predictive value of 76%, 67% and 63%, respectively.
