We report a case of nonischemic priapism following brachytherapy. A 63-year-old man presented 22 days after brachytherapy for prostate cancer. He suffered painless sustained incomplete erection for a few days. The patient was diagnosed with nonischemic priapism by cavernosal blood gas analysis. Right internal pudendal arteriography showed blood pooling in the cavernosum caused by arteriovenous fistula. Selective arterial embolization with gelatin sponge particles was performed and detumescence achieved. To our knowledge,this is the first case of high flow priapism caused by brachytherapy for prostate cancer...

The radial artery puncture is a frequently ordered medical procedure for patients requiring blood gas analysis. Deviating from the proper procedure increases the likelihood of error and jeopardizes patient safety. The teaching methodology for the radial artery puncture is rarely addressed in the medical literature. First-year respiratory care students enrolled in a clinical practice course participated in an expanded curriculum on arterial puncture technique. The new five-step curriculum included: 1) a face-to-face lecture, 2) radial artery localization, 3) blunt-tipped needle simulation, 4) manikin arm puncture, and 5) a peer assessment video...

Therapeutic hypercapnia has the potential for neuroprotection after global cerebral ischemia. Here we further investigated the effects of different degrees of acute systemic hypoxia in combination with hypercapnia on brain damage in a rat model of hypoxia and ischemia. Adult wistar rats underwent unilateral common carotid artery (CCA) ligation for 60 min followed by ventilation with normoxic or systemic hypoxic gas containing 11%O2,13%O2,15%O2 and 18%O2 (targeted to PaO2 30-39 mmHg, 40-49 mmHg, 50-59 mmHg, and 60-69 mmHg, respectively) or systemic hypoxic gas containing 8% carbon dioxide (targeted to PaCO2 60-80 mmHg) for 180 min...

The objective of this study was to evaluate the effect of altitude on arterial blood-gases and hematocrit in Angus-based calves. It was hypothesized that alveolar ventilation rate, as indicated by arterial pCO, would increase with altitude but hematocrit would not. Five Angus-based herds ( = 30 to 80 per cohort) located at 105 m, 1,470 m, 2,010 m, 2,170 m, and 2,730 m above sea level were enrolled in this prospective cohort study. A portable analyzer measured blood-gas tensions in coccygeal arterial blood. Calves at 1,470 m, 2,170 m, and 2,730 m were sampled twice, at approximately 4 mo and 7 mo of age...

AIMS: Acute lung injury (ALI) is associated with excessive mortality and lacks appropriate therapy. Ghrelin is a novel peptide that protects the lung against ALI. This study aimed to investigate the role of endogenous ghrelin in the pathogenesis of ALI. MAIN METHODS: We used a rat oleic acid (OA)-induced ALI model. Pulmonary impairment was detected by hematoxylin and eosin (HE) staining, lung mechanics, wet/dry weight ratio, and arterial blood gas analysis. Plasma and lung content of ghrelin was examined by ELISA, and mRNA expression of ghrelin was measured by quantitative real-time PCR...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

BACKGROUND: Almost all international guidelines recommend corticosteroids for management of exacerbations of chronic obstructive pulmonary disease (COPD), because it leads to improved outcomes of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Nevertheless, due to its side effects, there are still concerns regarding the use of systemic corticosteroid (SC). Inhaled corticosteroids (IC) can be used as an alternative to SC, while reducing the risk of occurrence of side effects...

The arterial blood gas (ABG) test is used to assess gas exchange in the lung, and the acid-base level in the blood. However, it is still unclear whether or not ABG test indexes correlate with paraquat (PQ) poisoning. This study investigates the predictive value of ABG tests in prognosing patients with PQ poisoning; it also identifies the most significant indexes of the ABG test. An intelligent machine learning-based system was established to effectively give prognostic analysis of patients with PQ poisoning based on ABG indexes...

REVIEW
Samir Nusair
The incremental cardiopulmonary exercise test (CPET) is an increasingly used diagnostic method that serves to evaluate patients with chief complaint of dyspnea during exercise. Performing maximal symptom-limited CPET can show if the tested subject has a reduced exercise capacity and give clues to the mechanism of such exercise capacity reduction, cardiac, pulmonary, or pulmonary vascular source. In this review, it is suggested that the evaluation of the complex results of CPET should be performed by first determining if myocardial/circulatory insufficiency is present and second if there is gas exchange abnormality...

INTRODUCTION: In the emergency department (ED), lactate is routinely used for risk stratification. Whether venous or arterial lactate measured on blood gas is interchangeable is not known. We hypothesized that venous lactate can be used instead of arterial lactate for the evaluation of acute patients in the ED. PATIENTS AND METHODS: This was a prospective single-center study. All patients requiring a lactate measurement were enrolled and we simultaneously drew arterial and venous blood...

QUESTIONS UNDER STUDY: Transcutaneous measurement of carbon dioxide (PtCO2) has been suggested as an alternative to invasively obtained PaCO2 for the monitoring of patients with hypercapnic respiratory failure during noninvasive ventilation (NIV). Current data on monitoring in hypoxaemic respiratory failure are scarce and show conflicting results in hypercapnic patients in the emergency department. METHODS AND SETTING: We performed a retrospective comparison of real-time PtCO2 (SenTec Digital Monitor) and arterial/venous carbon dioxide tension (PaCO2/PvCO2) measurements in patients with severe hypoxaemic and/or hypercapnic respiratory failure during NIV...
