Abstract
Troponin is an important diagnostic tool, however, as the assay sensitivity and frequency of testing has increased in the COVID-19 era, a new cohort of patients with persistently elevated troponin has emerged. Interfering antibodies should be considered in patients with persistent and stable troponin elevation, where there is no ongoing cause.

Abstract
BACKGROUND Diazoxide is widely used to manage congenital hyperinsulinism and is generally well tolerated. Pericardial effusion is not a recognized side effect of diazoxide, apart from 2 single case reports. CASE DESCRIPTION Three patients with congenital hyperinsulinism developed pericardial effusion at the ages of 7 weeks, 8 months, and 17 years. The duration of diazoxide treatment (10-15 mg/kg/day) was 6.5 weeks, 5 months, and 17 years, respectively. There was no evidence of fluid overload or significant other cardiac anomaly. The 7-week-old patient presented with signs of cardiac failure, was treated with diuretics, and the effusion resolved after cessation of diazoxide. The 8-month-old patient required emergency subxiphoid drainage of the effusion due to hemodynamic compromise. The pericardial fluid had high numbers of polymorphonuclear cells, but did not grow any organisms, and histology showed non-specific chronic reactive changes; the effusion did not recur after cessation of diazoxide. The 17-year-old patient presented with atrial fibrillation, was treated with beta blockade and colchicine, and continues on diazoxide with monitoring of the effusion by ultrasound. CONCLUSION Patients on long-term diazoxide treatment may be at risk of pericardial effusion, the timing and significance of which is unpredictable. The duration of diazoxide treatment before presentation of pericardial effusion varied in our patients from weeks to years. We advise serial echocardiography 1-2 months after commencement of diazoxide and annually thereafter.

Abstract
In November 2014, New South Wales Health was notified of a cluster of respiratory illness in a veterinary school. Active case finding identified another case at a local equine stud. All cases had exposure to the equine fetal membranes of Mare A. This tissue subsequently tested positive for Chlamydia psittaci using quantitative real-time polymerase chain reaction. We conducted a cohort study of the university and stud farm staff to determine risk factors for disease. Nine people were exposed to the fetal membranes of Mare A. Of these, five cases of psittacosis were identified. Two required hospital admission. Contact with birds was not associated with illness (RR = 0.5, 95% CI = 0.09-2.73). People who had direct contact with the abnormal fetal membranes were more likely to develop disease (RR = 11.77, 95% CI = 1.02-∞). The emergence of an association between horse exposure and C. psittaci infection has important implications for the prevention and control of psittacosis. Article summary line: Investigation of an outbreak of psittacosis in a rural veterinary school demonstrates novel source of infection for psittacosis through exposure to abnormal equine fetal membranes.

Abstract
OBJECTIVE To conduct a survey to profile the practice of regional anesthesia in Chile and determine the limitations on its use. MATERIAL AND METHODS A link to an online questionnaire was sent by e-mail to anesthesiologists who were members of their national professional association (Sociedad Chilena de Anestesiologia). The survey was processed anonymously. Multiple choice items elicited responses concerning general demographic information, professional experience as an anesthetist, academic degree, hospital size, and the use of regional anesthesia in clinical practice (number of procedures and types of techniques). Finally, the questionnaire focused on the use of nerve and plexus blocks. RESULTS A total of 209 completed questionnaires were received, for a response rate of 54%. Regional anesthesia was part of routine practice for 97% of the respondents; 68% reported that regional techniques were used in more than 30% of their caseload. Most performed neuraxial techniques: 98.1% were spinal blocks, 96.2% lumbar epidural blocks, and 66.9% thoracic epidural blocks. Routine use of peripheral nerve blockade was reported by 73.7%. Upper limb anesthesia was provided significantly more often than lower limb anesthesia (P =.011). The most common technique involved use of a peripheral nerve stimulator (64%). Skills were mainly acquired through residency programs (68.9%) and self-teaching (20.1%). Peripheral nerve blocks were never performed by 26.3% of the respondents; the reason given most often was lack of training. CONCLUSIONS Although regional anesthesia is commonly used in Chile, neuraxial blocks remain the most frequently used types. Peripheral nerve blocks are used fairly often, mostly on an upper limb. Training should stimulate attempts to promote more widespread use of all forms of regional anesthesia.

Abstract
A survey was conducted in 2002 to determine the pattern of factor prophylaxis use in boys <or=18 years of age with haemophilia followed in North American treatment centres. Responses were obtained from 4553 cases (74% haemophilia A, 26% haemophilia B). The frequency of prophylaxis, defined as factor infusion greater than or equal to once per week for >or=45 weeks per year, was significantly higher for haemophilia A vs. haemophilia B cases (51% vs. 32%, P< 0.0001), and for boys with severe haemophilia A living in Canada vs. the USA (77% vs. 47%, P< 0.0001). Use of full-dose prophylaxis, defined as the infusion of 25-40 IU kg(-1) of factor VIII on alternate days (minimum three times per week) or 25-40 IU kg(-1) of factor IX twice weekly, was similar for boys <or=5 years of age in both Canada and the USA (30% and 33% haemophilia A and 35% and 13% haemophilia B). Reasons for initiating prophylaxis included a history of joint bleeding (88%) and age <or=2 years (23%). For prophylaxis triggered by joint bleeding, 38% of haemophilia treatment centres indicated that they would initiate prophylaxis after the first joint bleed and 66% after a history of target joint bleeding, defined most frequently as 2-4 bleeds over a 3-6 consecutive month period. A central venous line was used to ensure easy venous access for full-dose prophylaxis therapy in 80% of boys <or=5 years of age. These data offer a basis for projecting long-term factor concentrate needs for persons with haemophilia living in North America.

Abstract
Relief of pain in children is a challenge to the pediatric health care provider. A clear understanding of the various developmental and cognitive levels will help the nurse better assess and manage children in pain. Age-appropriate assessment tools are currently available. A combination of a wide variety of treatment modalities, both pharmacologic and nonpharmacologic, can be used to effectively manage pain in children.
