The objectives of the study were to describe a novel presentation of tetanus and to review the course of the respiratory component and the treatment and management of the disease. A case report is presented with a review of a 25-year experience at Mayo Clinic. We describe the case of a 65-year-old woman who presented with persistent hiccups, dyspnea, and pleurisy of 3 days duration that was caused by tetanus from inadequate secondary immunity. She required intubation for progressive trismus and laryngospasm-associated respiratory failure. Infusion of lorazepam did not control her spasms. Refractory spasms and hiccups resolved with fentanyl and cisatracurium therapy. After 3 weeks, the patient was weaned from the ventilator with complete recovery. In the past 25 years, nine additional patients have presented to Mayo Clinic with acute tetanus. Respiratory failure requiring intubation developed in seven patients, and six of the seven intubated patients survived with minimal deficits. The prognosis of tetanus is favorable if it is diagnosed promptly and if treatment and supportive measures are begun. To our knowledge, this is the first report of a patient with acute tetanus presenting with hiccups. This report also confirms the results of previous studies that suggested a need for improved immunity in the elderly population.

The purpose of the present study was to determine the symptomatology, diagnostic procedures, and therapeutic strategies of patients with an isolated unilateral absence of a pulmonary artery (UAPA).

New biomarkers, such as cardiac troponins, have a major role to play for cost-effective management of individuals with acute chest pain and suspected coronary syndrome, and the laboratory is now poised to assume a vital role in assessing damage and determining prognosis. The redefined biochemical criterion proposed to classify acute coronary syndrome patients presenting with ischemic symptoms as patients with myocardial infarction is heavily predicated on an increased troponin concentration in blood. In an era of evidence-based medicine, we can no longer overlook the diagnostic and prognostic benefits provided by the measurement of these highly sensitive and specific proteins.

To determine the benefit of IV beta(2)-agonists for severe acute asthma treated in the emergency department (ED).

The aim of this article was to identify the most common sites of obstruction in patients with obstructive sleep apnea (OSA) by a systematic review of published studies.

To provide a systematic overview of the literature investigating patient and tumor factors that are predictive of survival for patients with non-small cell lung cancer (NSCLC), and to analyze patterns in the design of these studies in order to highlight problematic aspects of their design and to advocate for appropriate directions of future studies.

With the development of percutaneous inferior vena cava (IVC) filters, IVC interruption has become a widely used procedure in patients with or at risk for venous thromboembolism. In an attempt at clarifying the indications for filter placement, a systematic literature review was undertaken.

Traumatic brain injury (TBI) is a major cause of disability and death in most Western nations and consumes an estimated $100 billion annually in the United States alone. In the last 2 decades, the management of TBI has evolved dramatically, as a result of a more thorough understanding of the physiologic events leading to secondary neuronal injury as well as advances in the care of critically ill patients. However, it is likely that many patients with TBI are not treated according to current treatment principles. This article presents an overview of the current management of patients with TBI.

The incidence of aortic dissection ranges from 5 to 30 cases per million people per year, depending on the prevalence of risk factors in the study population. Although the disease is uncommon, its outcome is frequently fatal, and many patients with aortic dissection die before presentation to the hospital or prior to diagnosis. While pain is the most common symptom of aortic dissection, more than one-third of patients may develop a myriad of symptoms secondary to the involvement of the organ systems. Physical findings may be absent or, if present, could be suggestive of a diverse range of other conditions. Keeping a high clinical index of suspicion is mandatory for the accurate and rapid diagnosis of aortic dissection. CT scanning, MRI, and transesophageal echocardiography are all fairly accurate modalities that are used to diagnose aortic dissection, but each is fraught with certain limitations. The choice of the diagnostic modality depends, to a great extent, on the availability and expertise at the given institution. The management of aortic dissection has consisted of aggressive antihypertensive treatment, when associated with systemic hypertension, and surgery. Recently, endovascular stent placement has been used for the treatment of aortic dissection in select patient populations, but the experience is limited. The technique could be an option for patients who are poor surgical candidates, or in whom the risk of complications is gravely high, especially so in the patients with distal dissections. The clinical, diagnostic, and management perspectives on aortic dissection and its variants, aortic intramural hematoma and atherosclerotic aortic ulcer, are reviewed.

One hundred fifty-two cases of fungal endocarditis (FE) were identified in the English-language literature between January 1, 1995, and June 30, 2000. Although the median age of patients (44 years) was relatively young, injection drug use was identified as a risk factor in only 4.1% of cases. Other factors, including underlying cardiac abnormalities (47.3%), prosthetic valves (44.6%), and central venous catheters (30.4%), were more commonly identified as predisposing conditions and reflect the changing epidemiology of the syndrome. Unfortunately, mortality remains unacceptably high, particularly for patients with Aspergillus-related FE. Novel therapies are needed to improve patient outcomes.

To describe the pharmacokinetics and bioavailability of inhaled tobramycin (TOBI; Chiron Corporation; Seattle, WA), 300-mg dose, delivered by a nebulizer (PARI LC Plus; Pari Respiratory; Richmond, VA) and a compressor (Pulmo-Aide, model 5650D; DeVilbiss Health Care; Somerset, PA) in cystic fibrosis (CF) patients during the pivotal phase III trials.

Since the late 1980s, there has been considerable clinical and academic interest in the use of continuous aerosolized bronchodilators for the treatment of patients with acute asthma. These studies have suggested that this therapy is safe, is at least as effective as intermittent nebulization, and may be superior to intermittent nebulization in patients with the most severely impaired pulmonary function.

Cysteinyl leukotrienes are important proinflammatory mediators in the pathogenesis of asthma. Since bronchial hyperresponsiveness is a noninvasive surrogate marker of asthmatic airway inflammation, we evaluated the bronchoprotection afforded by leukotriene receptor antagonists (LTRAs).

Four cases of primary endobronchial actinomycosis associated with an inhaled foreign body are described. In the light of these cases and those previously reported in the literature, we describe the main features of this uncommon association. All patients were > 55 years old, were predominantly men, and were usually in a debilitated state. In > 50% of cases, the clinical presentation was suggestive of lung cancer. Thoracic CT rarely revealed a foreign body, but the granulomatous reaction of the bronchial wall was sometimes suggestive of bronchial thickening. Sulfur granules identified on bronchial biopsies were highly suggestive of actinomycosis in most cases, but microbiological culture findings were usually negative. Antibiotics generally ensure good recovery. Extraction of the foreign body was delayed after antibiotic therapy in one half of cases, suggesting the need for endoscopic follow-up in bronchial actinomycosis.
