A 75-year-old Japanese woman presented with acute flushing pruritus and a feeling of diffuse warmth followed by collapse while dancing. After resting for 30 min and receiving a rapid infusion of 0.9% sodium chloride, her condition stabilised. She admitted that she had a similar experience 2 years earlier while dancing. Based on her history, her symptoms were attributed to exercise-induced anaphylaxis. None of the episodes was associated with any other suspicious cotriggers of anaphylaxis. She was successfully discharged from the clinic without any complications after receiving careful guidance on how to prevent this condition...

BACKGROUND: Severity of pulmonary hypertension (PH) in dogs is related to clinical signs and prognosis. HYPOTHESIS/OBJECTIVES: We hypothesized that Doppler echocardiographic (DE) indices of pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) are influenced by independent factors that create clinically important variability of DE-based estimates of PH in dogs. ANIMALS: Thirty-eight client owned dogs with naturally acquired degenerative atrioventricular valve disease and tricuspid regurgitation (TR)...

Memory impairments are a frequently reported cognitive symptom in people suffering from major depressive disorder (MDD) and often persist despite antidepressant therapy. Neuroimaging studies have identified abnormal hippocampal activity during memory processes in MDD. Exercise as an ad-on treatment for MDD is a promising therapeutic strategy shown to improve mood, cognitive function, and neural structure and function. To advance our understanding of how exercise impacts neural function in MDD, we must also understand how exercise impacts healthy individuals without MDD...

[Purpose] There are no reliable evidences that the weakening of intrinsic foot muscles causes the decrease of the medial longitudinal arch (MLA) height. The purpose of this study was to confirm whether the fatigue of intrinsic foot muscles decrease the MLA height during standing and gait using 3D motion analysis system. [Subjects and Methods] Twenty healthy male subjects participated in this study. Foot kinematics was measured using an Oxford Foot Model before and after fatigue-inducing exercises of the abductor hallucis and flexor hallucis brevis muscles...

Long-distance athletes are at risk of serious fluid and electrolyte disturbances, such as hypernatraemia (dehydration). Recently, cases of serious morbidity have been reported, due to acute exercise-associated hyponatraemia, which can advance to encephalopathy. An arterial blood gas analysis (ABG) was drawn from collapsed athletes at the championship of full-distance triathlon 2015, and different electrolyte imbalances were found. Our findings show that prehospital ABG can assist in differentiating the cause of collapse, and presumably, targeted treatment can be initiated already on scene...

BACKGROUND: Lack of agreement about criteria and terminology for children's language problems affects access to services as well as hindering research and practice. We report the second phase of a study using an online Delphi method to address these issues. In the first phase, we focused on criteria for language disorder. Here we consider terminology. METHODS: The Delphi method is an iterative process in which an initial set of statements is rated by a panel of experts, who then have the opportunity to view anonymised ratings from other panel members...

Exercise-inducible laryngeal obstruction (EILO) has been recognized as a not rare respiratory problem in youth practicing sports. The aim of the study was to test the mechanosensitivity of the larynx, and to identify the factors affecting it in a group of youth with proven EILO. Laryngeal sensory testing was performed in 54 adolescents and young adults with EILO. Laryngeal mucosal alterations were assessed according to the Reflux Finding Score (RFS). The data concerning diseases possibly affecting the upper airway, findings of previously performed flexible videolaryngoscopy during exercise, and RFS score were compared between the participants with laryngeal hyposensitivity and those with normal sensitivity...

BACKGROUND: Exercise-induced collapse (EIC) due to DNM1 mutation and rupture of the cranial cruciate ligament are both common syndromes in the Labrador retriever breed. A cohort of 313 Labradors was recruited based on their CCLR status and were subsequently genetically tested for EIC. Epidemiological aspects of the cohort were also described, including sex, sterilization status, and age at sterilization. RESULTS: No sex difference was observed in dogs susceptible to EIC (homozygous for the mutant genotype) compared to dogs not susceptible to EIC (heterozygotes and dogs homozygous for the normal genotype)...

Off-season training in year-round collegiate football is purported to be performance enhancing. Absent principles of exercise physiology, excesses in sport-training regimens pose risk to the participant athletes. Since 2000, 33 National Collegiate Athletic Association (NCAA) football players have died in sport: 27 nontraumatic deaths and 6 traumatic deaths, a ratio of 4.5 nontraumatic deaths for every traumatic death. On average, 2 NCAA football players die per season. Best practices, consensus guidelines, and precautions are ignored, elevating the risk...

Causes of sudden cardiac deaths have been widely reported with limited data focused specifically on myocarditis. A retrospective review of cases from the Office of the Chief Medical Examiner (OCME), State of Maryland yielded a total of 103 sudden unexpected deaths (SUDs) due to myocarditis (0.17% of all SUDs and 0.70% of autopsied SUDs) from 2005 through 2014. Most deaths occurred in patients <30 years of age with a male:female ratio 1.3:1. Of the 103 cases, 45 (43.7%) patients were witnessed collapsed. Four deaths occurred during exertion, such as exercising at the gym or performing heavy physical work, and 2 deaths were associated with emotional stress...

BACKGROUND: Cystic fibrosis lung disease is generally a diffuse process however rarely one lung may become particularly damaged through chronic collapse and consolidation resulting in end-stage bronchiectasis with relative sparing of the contralateral lung. This clinical situation is sometimes referred to as "destroyed lung". Lung resection surgery is seldom indicated in cystic fibrosis and the associated medical literature is relatively sparse.

INTRODUCTION: Humeral head necrosis (HHN) remains a major problem in fracture care. Neither its occurrence, its extend, nor its impact on clinical outcomes is predictable on the long term. This study was designed to evaluate clinical and radiological outcomes in patients depending on the influence of HHN. PATIENTS AND METHODS: 32 patients with a 3-6 year follow up participated in this study. Their humeral fractures had been stabilized with a standard Targon PH nail (Aesculap, Tuttlingen, Germany) for an acute humeral head fracture...

Completed surveys were obtained from owners of 165 border collies experiencing repeated episodes of abnormal gait or collapse during strenuous exercise. Unremarkable veterinary evaluation and lack of disease progression over time made common systemic, cardiac, and neurologic causes of exercise intolerance unlikely. Survey questions addressed signalment, age of onset, description of episodes, and owner perception of factors associated with collapse. Most dogs were young adults (median 2 yr) when episodes began, and they had experienced from 2 to more than 100 episodes (median 6) prior to their owners completing the survey...

BACKGROUND: Alcohol use is reported in university students with discrepancy between countries. The study objectives were to assess prevalence and associated factors of alcohol consumption among university students in Germany and China. METHODS: Data used were from 1853 Chinese and 3306 German university students. Alcohol consumption frequency was measured by a question "How often did you drink alcohol in the last three months?" with six possible responses, which were later collapsed into three categories of "At least once a week", "Less than once a week" and "Never"...

RATIONALE: Evaluation of military personnel for exertional dyspnea can present a diagnostic challenge, given multiple unique factors that include wide variation in military deployment. Initial consideration is given to common disorders such as asthma, exercise-induced bronchospasm, and inducible laryngeal obstruction. Excessive dynamic airway collapse has not been reported previously as a cause of dyspnea in these individuals. OBJECTIVES: To describe the clinical and imaging characteristics of military personnel with exertional dyspnea who were found to have excessive dynamic collapse of large airways during exercise...

OBJECTIVE: To review the efficacy of current treatment options for adults with obstructive sleep apnea (OSA). METHODS: Review of the literature. RESULTS: OSA, characterized by repetitive ≥ 10-second interruptions (apnea) or reductions (hypopnea) in airflow, is initiated by partial or complete collapse in the upper airway despite respiratory effort. When left untreated, OSA is associated with comorbid conditions, such as cardiovascular and metabolic diseases...

Intermittent claudication (IC) is the most commonly reported symptom of peripheral arterial disease (PAD). Impaired limb blood flow is a major casual factor of lower exercise tolerance in PAD but cannot entirely explain it. We hypothesized that IC is associated with structural changes of the capillary-mitochondria interface that could contribute to the reduction of exercise tolerance in IC patients. Capillary and mitochondrial morphometry were performed after light and transmission electron microscopy using vastus lateralis muscle biopsies of 14 IC patients and 10 age-matched controls, and peak power output (PPO) was determined for all participants using an incremental single-leg knee-extension protocol...

REVIEW
Brian J Krabak, Kelsey M Parker, Anthony DiGirolamo
Exercise-associated hyponatremia (EAH) is one of the most common causes of exercise-associated collapse. The primary pathogenesis of EAH is largely the result of excessive fluid intake but is influenced by other factors, including hormonal abnormalities (ie, inappropriate arginine vasopressin secretion), renal abnormalities, and mobilization of sodium stores. Early recognition of EAH is crucial to appropriate treatment, because symptoms are varied and may be confused with other causes of exercise-associated collapse...

Brachycephalic airway syndrome in dogs is typified by a variety of anatomical abnormalities causing a diverse spectrum of clinical signs of varying intensity. This variability makes the assessment of the surgical outcome after upper airway surgery difficult. Using a structured questionnaire, the present study investigated the dog owner-perceived severity and frequency of a broad spectrum of welfare-relevant impairments 2 weeks before and 6 months after brachycephalic dogs underwent a recently developed multi-level upper airway surgery...
