Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder which is characterised by variable symptoms, which include visual disturbances, headache, vomiting, seizures and altered consciousness. The exact pathophysiology of PRES has not been completely explained, but hypertension and endothelial injury seem to be almost always present. Vasoconstriction resulting in vasogenic and cytotoxic edema is suspected to be responsible for the clinical symptoms as well as the neuro-radiological presentation. ⋯ In conclusion, persistently elevated blood pressures remain the chief culprit for the clinical symptoms as well as the neurological deficits. Early diagnosis by diffusion weighted MRI scans, and differentiation from other causes of altered sensorium i.e. seizures, meningitis and psychosis, is extremely important to initiate treatment and prevent further complications. Although most cases resolve successfully and carry a favorable prognosis, patients with inadequate therapeutic support or delay in treatment may not project a positive outcome.

Extremely preterm birth reflects global disruption of the third trimester environment. Young adults born preterm have an adverse cardiovascular and metabolic health profile, together with molecular evidence of accelerated ageing and a reduced life expectancy. The underlying mechanism for these observations is unknown. This review summarises recent evidence of the lifetime effects of preterm birth and highlights the risks survivors face.

Historical Article
Learning from the past in the COVID-19 era: rediscovery of quarantine, previous pandemics, origin of hospitals and national healthcare systems, and ethics in medicine.
After the dramatic coronavirus outbreak at the end of 2019 in Wuhan, Hubei province, China, on 11 March 2020, a pandemic was declared by the WHO. Most countries worldwide imposed a quarantine or lockdown to their citizens, in an attempt to prevent uncontrolled infection from spreading. ⋯ In this educational paper, a historical overview from the sacred temples of ancient Greece-the cradle of medicine-to modern hospitals, along with the conceive of healthcare systems, is provided. A few foods for thought as to the conflict between ethics in medicine and shortage of personnel and financial resources in the coronavirus disease 2019 era are offered as well.

Comparative Study
Comparative evaluation of quality of diabetes care within a population using discrete HbA1c thresholds versus longitudinal trends within a defined time period.
HbA1c is a quality measurement for a population's diabetes care. Currently, discrete values are used to judge the care quality. However, an improved trend may have been achieved without reaching a discrete threshold. We aimed to compare the quality of glycaemic care using discrete thresholds versus longitudinal trends of a patient's HbA1c. ⋯ Our study highlights the need to consider longitudinal trends when measuring quality of diabetes care.

Randomized Controlled Trial
Drain in laparoscopic cholecystectomy in acute calculous cholecystitis: a randomised controlled study.
There is paucity of evidence regarding the role of drain in laparoscopic cholecystectomy (LC) in acute calculous cholecystitis (ACC), and surgeons have placed the drains based on their experiences, not on evidence-based guidelines. This study aims to assess the value of drain in LC for ACC in a randomised controlled prospective study. ⋯ Drains should not be placed routinely after LC in ACC as it increases pain and does not help in detecting or decreasing complications.
