A 78-year-old man was referred from his primary care clinic to the emergency department due to bluish discolouration of his lips and decreased oxygen saturation on pulse oximetry. The patient was asymptomatic. Physical exam was normal except for lip cyanosis. A CT pulmonary angiogram was negative for pulmonary embolism. Arterial blood gas (ABG) analysis with co-oximetry showed low oxyhaemoglobin, normal partial pressure of oxygen and methaemoglobinaemia, but an unexplained 'gap' in total haemoglobin saturation...

An 84-year-old man who had suffered from chronic obstructive pulmonary disease accompanied by moderate pneumonia as well as gastric cancer with liver metastasis was found dead by a nurse, who noticed that the patient's intravenous catheter in the left forearm had been erroneously connected to an oxygen supply in his hospital room, leading to infusion of oxygen into a vein. Postmortem CT scanning demonstrated multiple accumulations of gas in the pulmonary artery, the right atrium and ventricle, as well as the left subclavian and brachiocephalic veins, corresponding to the route that the infused gas would have taken to the heart and pulmonary artery...

Carfentanil is a fentanyl analog frequently used in large animal veterinary medicine. Recently, carfentanil has been discovered in postmortem and antemortem cases throughout the United States in the heroin supply either alone or mixed with heroin and/or other fentanyl analogs. The potency of carfentanil is ~10,000 times greater than morphine and 100 times greater than fentanyl. In two recent cases, carfentanil was identified and ruled to be the cause of death, either alone or in combination with other drugs...

A 25-year-old Caucasian man with a history of spherocytosis, splenectomy, recurrent blood transfusion, and no cardiopulmonary disease presented for an emergent laparoscopic cholecystectomy with a baseline pulse oximetric saturation (SpO2) of 88% while breathing room air. The SpO2 increased to only 89% during preoxygenation with an FIO2 1.0. Multiple arterial blood samples revealed SaO2 as high as 100% with PaO2 averaging 390 mm Hg. He was subsequently diagnosed with a dyshemoglobin, hemoglobin Köln. The simultaneous presentation of a stable patient from a cardiopulmonary perspective with normal arterial oxygen tension and saturation in the blood gas analyses despite a low SpO2 measurement outlines the importance of integrating the history of present illness and both the importance and the limitation of the pulse oximetry...

Infectious disease outbreaks often occur in the aftermath of catastrophic events, either natural or man-made. While natural disasters such as typhoons/hurricanes, flooding and earthquakes have been known to increase the risk of infectious disease outbreak, the impact of anthropogenic disasters is less well-understood. Kaohsiung City is located in southern Taiwan, where most dengue outbreaks had occurred in the past two decades. It is also the center of petrochemical industry in Taiwan with pipelines running underneath city streets...

The isolated epidural gas-containing pseudocyst is an uncommon pathogenic factor for severe pain of the lower limb as a result of nerve root compression. After reviewing these rare cases reported in the literature, we found that the name, pathogenesis, and treatment strategy of this pathology remained controversial. The most common treatment is conservative treatment or percutaneous aspiration which might result inpoor pain relief and high recurrence rates. Moreover, the patient who received open surgery had good clinical outcome; however, he or she might experience a significant soft tissue injury...
