This study was conducted at Aga Khan University Hospital, Karachi, Pakistan from March to July 2020. COVID-19 patients with neurological symptoms and positive neuroimaging were included after confirmation of COVID-19 by polymerase chain reaction test (PCR). In the 12 included patients, seizures and altered mentation were predominant neurological manifestations. Three cases had acute watershed infarcts (25%), two cases had posterior cerebral artery territorial infarcts (16.7%), two cases had periventricular corona radiata infarcts (16.7%), three cases had hypoxic ischemic encephalopathy (25%), two cases had posterior reversible encephalopathy syndrome (16.7%), and there was one case each of cerebral venous sinus thrombosis, pontine infarct, and bithalamic lesions (8.3%). This study highlights the diagnostic approaches in COVID-19-associated encephalopathy and the variable imaging features that clinicians and neuroradiologists should be aware of, as the pandemic progresses.

There is a dearth of evidence on mechanisms to provide optimum quality care to COVID-19 patients in the resource-constrained healthcare environment. The lessons learned from the Ebola virus outbreak for the deficient health systems and quality improvement are considered to propose strengthening the health systems response to deliver quality-assured care to patients during the current pandemic. In this regard, the World Health Organization (WHO) health systems framework can serve as a guiding principle towards providing quality-assured and safe healthcare services during the ongoing pandemic in Pakistan by ensuring the availability of an adequate workforce, medical supplies and equipment, strong governance, active information system, and adequate health financing to effectively manage COVID-19. Research evidence is needed to be better prepared for an effective and coordinated health systems response to offer quality and safe care to patients.

The polymerase chain reaction (PCR) test for SARS-CoV-2 has low sensitivity and is time-bound. Emergent surgical cases might not give ample time for SARS-CoV-2 evaluation. These issues have called for adaptation of an anesthesia technique that can ensure safety measures regarding airway management in emergent cases; and can limit the chances of viral spread in case the patient is a carrier of coronavirus disease 2019 (COVID-19). In this communication, we summarised the modifications required in anesthesia technique during intubation and extubation of a patient's airway that would decrease the risk of virus transmission to the operation theatre staff. Key Words COVID-19, SARS-CoV-2, Emergent surgeries, Anesthesia technique.Ophthalmology is a specialty which involves close contact with patients. Personal protective equipment (PPE) along with modifications in examination techniques and equipment are needed to avoid spread of coronavirus infectious disease (COVID-19) to health professionals. This communication aims to highlight and critically analyse the measures suggested to control this spread. We also highlighted our experience with protective gear modifications. As with any practice, triage is cornerstone. Use of disinfectants, good personal hygiene practices and PPE for patients and staff, must be adopted for safe ophthalmology practices. Key Words COVID-19, Ophthalmology, Personal protective equipment (PPE).The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease mainly affects respiratory system. Its common clinical findings include fever, cough and shortness of breath. Characteristic radiological features of the disease include peripherally distributed, bilateral ground-glass opacities, predominantly involving the lower lung zones. In this report, we present a case of COVID-19 disease presenting with spontaneous pneumothorax. A 26-year male patient was admitted to the Emergency Department with fever, dry cough, shortness of breath and right-sided chest pain. Radiographic imaging of the patient revealed pneumothorax on the right and peripherally distributed non-homogenous opacification. The patient underwent right lateral tube thoracostomy. COVID-19 was diagnosed on testing of nasopharyngeal swab. link2 In conclusion, spontaneous pneumothorax is one of the rare presentations of COVID-19 pneumonia and should be kept in mind in patients presenting with shortness of breath and chest pain. Key Words Spontaneous pneumothorax, Corona, pneumonia.We present a case of coronavirus disease 2019 (COVİD-19) re-infection where the time interval between two COVİD-positive episodes is the longest in the literature. A 40-year male patient was admitted to the Emergency Department with complaints of sore throat, cough and diarrhea; and was re-diagnosed as COVİD-19 positive after a virus-free period. He did not have a chronic disease in his anamnesis and used no medication. After COVİD-19 infection and a long recovery period, he became COVİD-19 positive again. In this case, the time to second COVİD-19 infection was 94 days from the first positive PCR test and 86 days from the complete resolution of symptoms. This is one of the longest COVID-19-free period between two episodes of infection in the literature. Key Words COVID-19, Recurrence, Re-infection, Recovery.ABSTRACT The clinical manifestations of coronavirus disease 2019 (COVID-19)-associated pneumonia show a wide range of variations. It ranges from mild hypoxemia without significant signs of respiratory distress, to rapid clinically deteriorating course with severe hypoxemia. Unexplained severe hypoxemia, associated with platypnea, triggers the possibility of ventilation-perfusion (V/Q) mismatch, ranging from intrapulmonary shunts (IPS) to alveolar dead space ventilation. In the literature, very few cases with COVID-19-pneumonia have been reported with IPS. Herein, we report a COVID-19 confirmed 45-year male patient, who developed IPS without apparent pulmonary perfusion defect on lung perfusion scintigraphy. The patient had no cardiovascular disease except chronic pulmonary hypertension secondary to interstitial lung disease. The clinical manifestations combined with nuclear imaging features enabled in making the ultimate diagnosis. The patient's clinical condition improved on appropriate clinical management, using high flow oxygen combined with intravenous steroids and anticoagulants.

These participants had received real-time reverse transcription-polymerase chain reaction (RT-PCR) and chest X-rays (CXRs) before diagnosis. The follow-up CXRs of three patients in the family showed significant progression, with COVID-19 pneumonia, clinically worsening in a short period of time. Therefore, the results of follow-up CXRs in the short-term may be an adjunctive diagnostic method for COVID-19 disease diagnosis and its progression.
