BACKGROUND: Repeated use of inhaled β2 agonists is common in asthma or COPD exacerbations. It can lead to hyperlactatemia. CASE REPORTS: We report two asthmatic patients who presented in the emergency department for an asthma exacerbation. The first patient developed hyperlactatemia at 3.9 mmol/L and the second patient developed hyperlactatemia at 5.6 mmol/L after terbutaline treatment. Both patients had a favorable outcome after adjusting the aerosol dose to clinical parameters...

An increasing number of reports describing Escherichia coli isolates with piperacillin/tazobactam resistance, despite retained cephalosporin susceptibility, suggest further emergence of this phenotypic resistance pattern. In this report, a patient with metastatic breast cancer presented to medical care after two days of chills, nausea, vomiting, reduced oral intake, and generalized weakness. Blood and urine cultures grew E. coli as identified by rapid diagnostics multiplex PCR and MALDI-TOF, respectively. The patient continued to manifest signs of sepsis with hypotension and tachypnea during the first three days of hospitalization despite empirical antimicrobial therapy with intravenous piperacillin/tazobactam...

Enterovirus D68 (EV-D68) is a causative agent of recent outbreaks of severe respiratory illness, pneumonia and acute flaccid myelitis (AFM) worldwide. The study of the pathogenesis, vaccines and anti-viral drugs for EV-D68 infection has been reported. Given the previously described mouse model of EV-D68, we sought to establish a neonatal mice model inducing both pneumonia and AFM. The neonatal BALB/c mice were inoculated intraperitoneally with the EV-D68 strain (named15296-virus) which was produced by the reverse genetics method...

We have previously introduced a model for closed-loop respiratory control incorporating an explicit conductance-based model of bursting pacemaker cells driven by hypoxia sensitive chemosensory feedback. Numerical solution of the model equations revealed two qualitatively distinct asymptotically stable dynamical behaviors: one analogous to regular breathing (eupnea), and a second analogous to pathologically rapid, shallow breathing (tachypnea). As an experimental test of this model, we created a hybrid in vitrolin silico circuit...

Mona Ahmed Ammar, Noha Sayed Hussein
Background: Traumatic brain injury (TBI) correlated with increased sympathetic activity on the expense of parasympathetic system due to loss of cortical control after brain injury. Manifestations of sympathetic storm include tachycardia, hypertension, tachypnea, and hyperthermia. The neuroprotective effects via reducing cerebral metabolism and lowering O2 and glucose consumption are the targets early after trauma. Beta-blockers reduce sympathetic activity. Objectives: We suppose that using propranolol blunts the sympathetic storming phenomenon as it is a nonselective β inhibitor and has a lipophilic property to steadily penetrate blood-brain barrier...

BACKGROUND: Negative pressure pulmonary edema (NPPE) is a rare complication that is more prevalent in young patients. NPPE usually results from acute upper airway obstruction, which is most commonly caused by laryngospasm during extubation. NPPE is characterized by the sudden onset of coughing, hemoptysis, tachycardia, tachypnea, and hypoxia, and is dramatically improved with supportive care, which prevents severe sequelae. To our knowledge, there is no report of a patient developing NPPE after percutaneous endoscopic interlaminar lumbar discectomy...

NEW FINDINGS: What is the central question of this study? Does carotid body input contribute to the hyperosmotic responses? What is the main finding and its importance? The response to NaCl overload is sympathorespiratory excitation. Eliminating the carotid body input reduced sympathoexcitation but did not affect the increase in phrenic burst frequency, whereas eliminating the hypothalamus prevented the tachypnoea and sympathoexcitation. We conclude that the carotid body inputs are essential for the full expression of the sympathetic activity during acute NaCl overload, whereas the tachypnoea depends on hypothalamic mechanisms...

Purpose: High-altitude pulmonary edema (HAPO) is an acute medical emergency occurring typically in lowlanders, who ascend rapidly to heights of 3000 m or more. It presents with marked dyspnea on exertion, fatigue with minimal-to-moderate effort, prolonged recovery time, and dry cough with manifestations of cyanosis, tachycardia, tachypnea, and temperature which generally does not increase beyond 38.5°C. The condition may be fatal if not treated in time with supplemental oxygen or hyperbaric oxygen or rapid descent to lower altitude...

We report a case series of four patients where tachypnea was observed during positive airway titration studies, double the baseline breathing rate (tachypnea range 46-68 breaths/min). It happened mainly during non-rapid eye movement to rapid eye movement sleep transitions without significant changes in oxygen saturation or signs of autonomic hyperactivity such as an increased heart rate. The increased respiratory rate may be a normal physiological extreme outlier seen during phasic rapid eye movement sleep triggered by high pressure ventilation and it may also indicate underlying ventilatory instability, making patients predisposed to central sleep apnea...

Altered mental status is a common, yet challenging, clinical presentation encountered by physicians. Here, we report a case of a 68-year-old Japanese female who was transferred to the emergency department due to faint. The laboratory results showed hyponatremia, ketonuria, hyperglycemia and acute kidney injury without fever or inflammatory findings. Although these abnormalities were corrected, her mental status was exacerbated, and apnea/tachypnea appeared. She was eventually diagnosed with acute apical abscess and recovered immediately after dental extractions...
