The Bronx Zoo says Nadia, her sister Azul, two Amur tigers and three African lions had developed a dry cough. They are all expected to recover.
We present a case of PPB in a 2-year-old girl who was brought to the pediatric clinic for fever, cough and respiratory distress. Imaging studies showed a heterogeneous solid-cystic mass (12∕9∕11 cm) in the upper right pulmonary lobe. Through right thoracotomy, a specimen was obtained, the histopathological and immunohistochemical features of the specimen being suggestive for type II PPB. Aggressive chemotherapy and right pneumonectomy resulted in control of disease, the patient being currently in complete remission four years after the diagnosis. PMID: 32239109 [PubMed - in process]
CONCLUSION: The prodromal symptoms of COVID-19 were mild and most patients did not have limitations of daily activity. Viral shedding from URT was high from the prodromal phase. Radiological pneumonia was common from the early days of illness, but it was frequently not evident in simple CXR. These findings could be plausible explanations for the easy and rapid spread of SARS-CoV-2 in the community. PMID: 32242348 [PubMed - in process]
A HEART ATTACK can be fatal. Although hospitals are having a tough time dealing with the coronavirus pandemic, a heart attack is a medical emergency. What's the type of cough associated with the disease?
Authors: Armstrong C, Kapolowicz MR Abstract Dextromethorphan, a common over-the-counter cough suppressant, has potential for abuse. In the present commentary, we summarize findings to suggest extensive dextromethorphan overuse/abuse within the U.S. military community residing in Okinawa, Japan. We first compared sales of dextromethorphan-containing medications within the U.S. military community of Okinawa, Japan with sales within the U.S military community from the other nearby locations in the Pacific region. Our report revealed that dextromethorphan use is far more prevalent within the military community in Okin...
The objective of this study was to test the value of adding a maximal inspiratory manoeuvre to basic spirometry to differentiate COPD and BA. One hundred forty-three COPD patients and 142 BA patients had measurements of maximal inspiratory and expiratory flow during routine spirometry. Parameters from these tests were used to assess diagnostic accuracy using receiver-operating characteristic (ROC) analyses followed by logistic regression. The association of two independent parameters were analyzed using linear regression analyses. Results show that forced expiratory volume in one second/forced vital capacity (FEV1/FVC%)
CONCLUSIONS: The ability to rapidly identify, propagate, and internationally share our SARS-CoV-2 isolate is an important step in collaborative scientific efforts to deal effectively with this international public health emergency by developing better diagnostic procedures, vaccine candidates, and antiviral agents.

If you just came back from an overseas trip with a fever and a cough, you'll be prioritized for a COVID-19 test in Manitoba and Nova Scotia, but not Alberta or Quebec. And some provinces are expanding who can get tests, as others narrow them. Why? And what does it mean for the accuracy of Canada's case numbers?
CORONAVIRUS testing is currently reserved for those showing extreme side effects of the disease, as they're usually admitted to hospital. But what about the milder symptoms? What's a persistent dry cough?
CONCLUSIONS: We posit the existence of a fourth common syndrome of COVID-19 infection: isolated sudden onset anosmia (ISOA) and urge the international community to consider this presentation in current management advice. PMID: 32240279 [PubMed - as supplied by publisher]
