Aconitine poisoning causes refractory ventricular arrhythmias (VAs). In a 20-year-old man, VAs of unknown etiology did not respond to drugs and electrical defibrillation. However, left stellate ganglion blockade (SGB) dramatically decreased arrhythmias without complications.

Purpose: Hyperglycemia has been associated with postoperative morbidity in patients who undergo cardiac surgery. However, it remains unclear whether the duration of hyperglycemia is as important as its magnitude in the development of postoperative end-organ dysfunction (PEOD). This retrospective study investigated the hypothesis that the intraoperative blood glucose (BG) exposure index (GE index), calculated by the product of the magnitude and duration of BG concentration ≥ 180 mg/dL, which is an integration of the severity and duration of hyperglycemia, is associated with the incidence of PEOD in patients undergoing cardiac surgery with cardiopulmonary bypass.

Background: Ruptured coronary artery aneurysm is rare, but the most serious complications of an acute phase of Kawasaki disease (KD) with giant coronary artery aneurysm (GCAA). Progressive or super GCAA, which rapidly dilates and continue to increase over a diameter of 10 mm, are more susceptible to rupture.

Case Summary: We report the case of a 6-year-old boy with KD who had multiple super GCAAs with a high risk of GCAA rupture.

Tracheobronchial adenoid cystic carcinoma is a rare malignancy. To the best of our knowledge, its enhancement pattern on multiphasic contrast-enhanced multidetector computed tomography has not been reported. Herein, we report the computed tomography findings of three consecutive cases of tracheobronchial adenoid cystic carcinoma.

Purpose: To observe arterial oxygen in relation to fraction of inspired oxygen (FO) during mechanical ventilation (MV).

Materials And Methods: In this multicenter prospective observational study, we included adult patients required MV for >48h during the period from March to May 2015. We obtained FO, PaO and SaO from commencement of MV until the 7th day of MV in the ICU.

Functions of the nervous system are supported by the flow of cerebrospinal fluid (CSF), which is driven by the ciliary beating of ventricular ependymal cells. The aim of the present study was to examine whether methylmercury (MeHg), a substance with potent neurotoxicity in humans, affects the ciliary movement. The effects of another organic mercury compound, ethylmercury (EtHg), were also assessed for comparison.

We report a very rare case of primary endobronchial peripheral T-cell lymphoma (PTCL) not otherwise specified (NOS), which presented as an endobronchial tumor obstructing the main airway. An 81-year-old man was referred to our hospital for a 1-month history of productive cough and wheeze. Computed tomography revealed chronic pyothorax with calcified foci in the right lung and a mass inside the bronchus intermedius.

Background: Although chloride is one of the major electrolytes measured routinely in dairy practice, the amount of attention chloride receives in critically ill patients is limited. There are still a few studies reporting the incidence of derangements of chloride and its association with patients' outcomes. Accordingly, we conducted a retrospective study to assess the prevalence of abnormality of serum chloride level in postoperative patients in the intensive care unit on the early phase of surgery and its association with outcome.

This study examined the causal links among job involvement (JI), career commitment (CC), affective commitment to the organization (ACO), and continuance commitment to the organization (CCO) under Japanese management practices. It was hypothesized that, JI influences CC, ACO and CCO directly, and influences ACO and CCO indirectly through CC. Survey data of 1470 male college-graduate white-colors were analyzed and results of path analysis (AMOS 4.
