    Anaphylactic reaction towards antibiotics is common during anaesthesia. It may present as bronchospasm, hypotension, desaturation, or urticarial. However it is uncommon for anaphylaxis reaction to present only as supraventricular tachycardia (SVT). This is a rare interesting case report on a 23-year-old healthy man whose anaesthetic categorization is American Society of Anaesthesiologist (ASA) 1, developed supraventricular tachycardia (SVT) towards intravenous cefuroxime, peri operatively. His condition resolved with carotid sinus massage. No pharmacological interventions were used. His skin prick intradermal tests showed allergies towards cefuroxime, cefazoline and cefoperazone. The patient subsequently underwent.

    The aim of the study was to determine the effect of pro-phylactic low dose dopamine infusion on renal function in ventilated premature newborns with respiratory dis-tress syndrome (RDS). A prospective, randomised con-trolled trial was conducted, using low dose dopamine [2.5μg/kg/min] in the treatment of preterm babies with gestational age 28-36 weeks requiring mechanical ventilation for RDS within six hours of age. Thirty-six babies were enrolled and 19 babies were randomly assigned to the treatment groups. The renal function after 72 hours for the treatment and control groups respectively were: urine output (ml/kg/hour) 3.3±0.4 and 3.0±0.3 [p=0.55], urine specific gravity 1006±0.6 and 1006±1.0 [p=0.68], fractional excretion of sodium 4.1±0.8 and 2.6±0.4 [p=0.10], fractional excretion of potassium 37.44 ± 5.6 and 16.49 ± 2.2 [p=0.001], glomerular filtration rate (ml/day/1.72m2) 16±2.6 and 25.6±4.5 [p=0.06]. There were no significant differ-ences in the frequency of hypotension, oliguria and sep-sis between the two groups. There were seven deaths (36.8%) in the treatment group (six due to sepsis and one due to prematurity) and two deaths (11.8%) in the control group (both due to sepsis) (p = 0.13). In con-clusion prophylactic low-dose dopamine infusion did not improve the renal function in ventilated premature babies with respiratory distress syndrome. The results of this study do not support the routine use of prophylac-tic low-dose dopamine in ventilated preterm babies with respiratory distress syndrome.

    Xylazine is an alpha-2agonist often used as a sedative, analgesic and muscle relaxant agent
    in animals. Xylazine was not accepted by Food and Drug Administration (FDA) for human use
    due to hazardous side effect such as hypotension, bradycardia, respiratory depression and coma.
    This is a rare case report of a 64-year-old farmer who accidentally injected himself with Xylazine
    which was supposed to be given to a fractious cow. He developed altered conscious level, hypotension, bradycardia and respiratory failure requiring mechanical ventilation. Fortunately, he
    recovered and was discharged home after three days. This occurred due to improper handling of
    Xylazine without standard operating procedures. Xylazine is regulated for animal use only. Therefore, effects of Xylazine toxicity in human must be emphasized for awareness on proper handling as well as for right management of its poisoning incident in future.

    Syzygium polyanthum (Wight) Walp. var. polyanthum leaves are consumed as a traditional Malay treatment of hypertension. This study investigates hypotensive potential of aqueous (AESP) and residual methanolic (met-AESP) extracts of S. polyanthum leaves and possible involvement of autonomic receptors. AESP and met-AESP (20 to 100 mg/kg) were intravenously administered into anaesthetized Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) rats. Blood pressure and heart were monitored for 20 min. AESP and met-AESP induced significant dose-dependent hypotension, but only 100 mg/kg AESP caused mild bradycardia (n = 5). AESP-induced hypotension was more potent than that of met-AESP in WKY. AESP has a faster onset time than that of met-AESP in both WKY and SHR. However, met-AESP-induced hypotension was more sustained than that of AESP in SHR. Blockages of autonomic ganglion and α -adrenergic receptors using hexamethonium and phentolamine (n = 5 for each group) partially attenuated AESP-induced hypotension, suggesting involvement of α -adrenergic receptors. Blockages of autonomic ganglion, β -adrenergic, cholinergic receptors, and nitric oxide production using hexamethonium, propranolol, atropine, and N- ω -nitro-l arginine methyl ester (L-NAME) (n = 5 for each group) partially attenuated met-AESP-induced hypotension, suggesting involvement of β -adrenergic and cholinergic receptors via nitric oxide production.

    The determination of cerebral perfusion pressure (CPP) is regarded as vital in monitoring patients with severe traumatic brain injury. Besides indicating the status of cerebral blood flow (CBF), it also reveals the status of intracranial pressure (ICP). The abnormal or suboptimal level of CPP is commonly correlated with high values of ICP and therefore with poor patient outcomes. Eighty-two patients were divided into three groups of patients receiving treatment based on CPP and CBF, ICP alone, and conservative methods during two different observation periods. The characteristics of these three groups were compared based on age, sex, time between injury and hospital arrival, Glasgow Coma Scale score, pupillary reaction to light, surgical intervention, and computerized tomography scanning findings according to the Marshall classification system. Only time between injury and arrival (p = 0.001) was statistically significant. There was a statistically significant difference in the proportions of good outcomes between the multimodality group compared with the group of patients that underwent a single intracranial-based monitoring method and the group that received no monitoring (p = 0.003) based on a disability rating scale after a follow up of 12 months. Death was the focus of outcome in this study in which the multimodality approach to monitoring had superior results.

    STUDY OBJECTIVE: To determine the efficacy of sedation with dexmedetomidine compared to propofol for claustrophobic adults undergoing magnetic resonance imaging (MRI) in our institution.

    DESIGN: Randomized, prospective, double-blinded study.

    SETTING: University-based tertiary referral center.

    PATIENTS: Thirty claustrophobic adults with American Society of Anesthesiologists physical status I and II who were planned for MRI.

    INTERVENTIONS: Patients were randomly assigned to target-controlled infusion propofol or dexmedetomidine loading followed by maintenance dose for procedural sedation.

    MEASUREMENTS AND MAIN RESULTS: The primary end point was adequate reduction in patient anxiety levels to allow successful completion of the MRI sequence. Both methods of sedation adequately reduced anxiety levels in visual analog scale scores and Spielberger Strait Test Anxiety Inventory (P

    Thrombolytic therapy remains widely used in majority of developing countries, where delivery
    of primary percutaneous coronary intervention (PCI) remains a challenge. Unfortunately,
    complications following such therapy remains prominent, predominantly bleeding-related
    problems. We present a rare case of massive renal subcapsular haemorrhage and hematoma
    following thrombolytic therapy. A 61-year old gentleman presented following an episode of
    chest pain due to acute ST-elevation myocardial infarction. Due to potential delays in obtaining
    PCI, the patient was counselled for thrombolysis using streptokinase which he had consented
    to. Unfortunately, within 36 hours of admission, he developed abdominal pain, haematuria,
    hypotension and altered mental status, associated with acute drops in haemoglobin levels.
    Following initial resuscitation efforts, a Computed Tomography scan of the abdomen was
    performed revealing a massive renal subcapsular hematoma, likely secondary to previous
    thrombolysis. Renal subcapsular hematoma can either be spontaneous or iatrogenic, the latter
    often due to coexisting renal-based neoplasm or vasculitidies. Iatrogenic causes include
    trauma, following renal biopsies or anticoagulation therapy amongst a few others. Iatrogenic
    renal subcapsular haemorrhage and hematoma formation are rare following thrombolysis. Our
    literature search revealed only one other similar case, although this was following
    administration of recombinant Tissue Plasminogen Activator in a case of acute ischaemic
    cerebrovascular accident. This case highlights the complexity in management, following the
    findings in terms of need for cessation of dual antiplatelet therapy and timing for PCI and stent
    selection.

    OBJECTIVE: To evaluate the association between intrauterine growth restriction (IUGR) and the incidence of fetuses with patent ductus arteriosus (PDA) and Hemodynamically significant PDA (Hs-PDA) in dichorionic twins (DC) with selective IUGR.

    MATERIALS AND METHODS: This is an observational cohort study and retrospective case assessment, involved twins born at Linkou Chang Gung Memorial Hospital, Taoyuan, Taiwan between 2013 and 2018. DC twins with selective IUGR (sIUGR) were defined as the presence of a birth weight discordance of >25% and a smaller twin with a birth weight below the tenth percentile. PDA was diagnosed using echocardiography between postnatal day 3 and 7. Hs-PDA was defined as PDA plus increased pulmonary circulation, poor systemic perfusion, cardiomegaly, pulmonary edema, or hypotension requiring pharmacotherapeutic intervention.

    RESULT: A total of 1187 twins were delivered during the study period, and 53 DC twins with selective IUGR were included in this study. DC twins with PDA have higher rate of preterm birth, lower gestational age of delivery, and lower mean birth weight of both twins compared with DC twins without PDA. In a comparison of the sIUGR twin with the appropriate for gestational age co-twin, both the incidences of PDA (28.30% vs. 7.55%, respectively; P = 0.003) and Hs-PDA (24.53% vs. 5.66%, respectively; P = 0.002) were higher in sIUGR fetuses than in the appropriate for gestational age co-twins. Small gestational age of delivery was the only variable to predict PDA and Hs-PDA [p = 0.002, Odds ratio = 0.57 (0.39-0.82), p = 0.009, Odds ratio = 0.71 (0.55-0.92), respectively].

    CONCLUSION: An analysis of dichorionic twins with sIUGR indicated that IUGR increased the risk of PDA and hemodynamically significant PDA.

    OBJECTIVE: To describe the glycaemic control, diabetes care and prevalence of complications in youth with type 2 diabetes from the Western Pacific Region.
    RESEARCH DESIGN AND METHODS: Cross-sectional, clinic-based audit of 331 patients aged < 18 years from 56 centres in Australia, China-Beijing, China-Shanghai, China-Hong Kong, Indonesia, Japan, South Korea, Malaysia, Philippines, Singapore, Taiwan and Thailand. Clinical and management data were recorded along with glycated haemoglobin (HbA(1c)), lipids and complication rates.
    MAIN OUTCOME MEASURES: Glycaemic control, complications, diabetes management.
    RESULTS: Median age was 14.9 years (interquartile range 13.2-16.4 years) and median diabetes duration 2.3 years (1.4-3.6 years). Median HbA(1c) was 7% (5.9-9.9%) and HbA(1c) was > 7.5% in 40% of patients. In multiple regression analysis, glycaemic control varied significantly between countries (p = 0.02); higher HbA(1c) was associated with fewer home blood glucose measurements (p = 0.005) and higher insulin dose/kg (p < 0.0001). Blood glucose monitoring was performed by 65% of patients (range 33-96% by country). In 25% of patients, management consisted of diet alone or no treatment (range 0-53% by country); oral anti-diabetic drugs alone were used in 49%, insulin alone in 11% and both in 15%. Microalbuminuria was found in 8% and hypertension in 24%. The risk of hypertension increased with higher BMI (OR 1.16, 95% CI 1.09-1.24, p < 0.0001); antihypertensive agents were used in 4% of patients.
    CONCLUSIONS: The management of type 2 diabetes in youth from the Western Pacific Region varies widely. Hypertension and microalbuminuria were frequent, but not commonly treated. Further investigation into the natural history and risk factors for complications in youth with type 2 diabetes is required to assist in developing evidence based management guidelines.
