Enhanced sympathetic activity causes an exaggerated heart rate response to standing in the postural tachycardia syndrome (POTS). All patients describe symptoms of orthostatic intolerance such as dizziness, blurred vision, shortness of breath, palpitations, tremulousness, chest discomfort, headache, lightheadedness and nausea, but only one third suffer loss of consciousness. We report four patients with POTS, who had long ventricular pauses (i.e. asystole) and syncope during head-up tilt test. This suggests that a subset of patients with POTS can have a surge in parasympathetic outflow that precedes vasovagal syncope.

In the afternoon of March 23, 2006 a Providence firefighter was diagnosed as having cyanide poisoning after working at a building fire. In the aftermath of three fires at commercial and residential sites that day, eight additional firefighters (out of 28 tested) were found to have elevated levels of cyanide. Numerous other members reported symptoms consistent with cyanide poisoning, including headaches, weakness and fatigue, nausea, and shortness of breath. The Providence Fire Department (PFD) established a joint union management committee to review the situation.

A coronary artery fistula is a direct communication between a coronary artery and one of the cardiac chambers or vessels around the heart. These fistulas are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. Bilateral coronary fistulas between coronary arteries and the pulmonary artery are very rare. This report describes a 51-year-old man without any previous medical history, who presented to our hospital one hour after the acute onset of severe substernal chest pain associated with shortness of breath and nausea. Coronary angiography revealed two fistulas arising from the left anterior descending and right coronary arteries and draining at exactly the same site in the pulmonary artery. There was no evidence of atherosclerotic coronary artery disease in either the left or right coronary arterial tree.

A substantial number of individuals evaluated for complaints of chest pain do not suffer from coronary heart disease (CHD). Studies show that many patients who complain of symptoms that might be caused by CHD, such as shortness of breath or chest pain, may actually have an anxiety disorder. Gender differences in how patients present with these symptoms have not been adequately explored. The purpose of this study was to explore possible gender differences in the presentation of patients with CHD-like symptoms. Two groups were examined, one comprising 6,381 individuals self-referred for electron beam tomography (EBT) studies and a subset of these individuals who defined a "low-risk" group based on the absence of risk factors for CHD and low coronary artery calcium (CAC) scores. We explored gender differences in symptom presentation in each group after controlling for relevant variables by using logistic regression models. These analyses showed that women were significantly more likely than men to endorse CHD symptoms that might also be caused by an anxiety disorder. Women in the low risk group reported CHD symptoms also referable to anxiety more often than men, but unlike men did not complain primarily of chest pain. Women were also more likely to have been prescribed antianxiety or antidepressant medication. In previous studies, non-cardiac chest pain has been considered a hallmark of anxiety in individuals seen in medical settings. This study suggests that in individuals with low risk for CHD chest pain was not related to gender, but other anxiety-related symptoms including heart flutter, lightheadedness, nausea, and shortness of breath were more likely to be reported in women than in men.

The "magic bullet" era of targeted cancer therapy began with the United States Food and Drug Administration approval of rituximab for the treatment of B-cell lymphoma in the late fall of 1997. Since then, several additional anticancer antibody products have received regulatory approval, including the monoclonal antibodies (MoAbs) trastuzumab for breast cancer and alemtuzumab for chronic lymphocytic leukemia, and the MoAb immunoconjugates gemtuzumab ozogamicin for acute myelogenous leukemia and yttrium 90 ibritumomab tiuxetan for B-cell lymphoma. These products are associated with adverse events that are quite different than those seen with chemotherapy. Adverse events associated with MoAb products typically have 1 of 3 etiologies: direct and indirect effects of antibody-antigen interaction, effects of toxins or radioisotopes that have been conjugated to antibodies, and allergic and hypersensitivity reactions to foreign protein. The infusion-related symptom complex is the most common and predictable side effect associated with all MoAbs that react with circulating blood cells. This pattern of various systemic effects includes flu-like symptoms such as headache, shortness of breath, fever, skin rash, hypotension, nausea, and asthenia, but usually occurs only in association with the first of any series of weekly infusions. The severity of these reactions is influenced by the rate of infusion, and the syndrome is the consequence of cytokines released from immune cells. Severe hypotension, bronchospasm, hypoxia, and even death have occurred. A true tumor lysis syndrome may occur if there are large numbers of proliferating antigen-positive cells in the blood. Symptoms related to the infusion reaction are ameliorated by slowing or stopping the infusion and administering antiinflammatory agents and antihistamines.

This study was designed to prospectively evaluate quality of life in patients treated with local external beam radiation therapy for symptomatic bone metastases. Patients with symptomatic bone metastases treated with palliative radiation therapy were followed with Edmonton Symptom Assessment Scale (ESAS) at baseline and at 1, 2, 4, 8, and 12 weeks after the delivery of radiation therapy. The ESAS evaluates 10 symptoms: global pain, index pain (pain at the irradiated site), fatigue, nausea, depression, anxiety, drowsiness, appetite, sense of well-being, and shortness of breath on a categorical score of 0 to 10 (0 = absence of symptom, 10 = worst possible symptom). At each follow-up interval, the difference for each domain of the ESAS was compared with the baseline score. A P value < 0.01 was considered significant. Five hundred and eighteen patients were analyzed in this study. For the entire cohort, there were statistically significant improvements with the delivery of palliative radiation therapy in global pain, index pain, anxiety, sense of wellbeing, and shortness of breath in >/= 1 follow-up interval. Fatigue was reported to be slightly worse in the first 2 weeks following the radiation treatment. Global pain, index pain, anxiety, and sense of well-being showed consistent improvement with the radiation treatment regardless of which endpoint definitions were employed. Radiation therapy not only can palliate pain but also can improve quality of life.

Severe ovarian hyperstimulation syndrome (OHSS) is a serious and potentially fatal complication of ovarian stimulation. A 29-year-old nulligravid patient with anovulatory infertility was treated with in vitro fertilization. Six days after embryo transfer, the patient presented with complaint of abdominal bloating, nausea, vomiting and shortness of breath. Severe late-onset OHSS, with massive ascites and pleural effusion, was diagnosed. Posterior colpotomy was performed under general anesthesia, a Foley catheter was inserted into the posterior cul-de-sac, and bilateral chest drainage tubes were left for continuous drainage. In total, 13.2 liters of ascites and 6.1 liters of pleural fluid were drained in 8 days. Continuous drainage of ascites and pleural effusion improved the patient's comfort without need for repeated transvaginal and thoracic aspirations.

Natural Language Processing (NLP) offers an approach for capturing data from narratives and creating structured reports for further computer processing. We explored the ability of a NLP system, Medical Language Extraction and Encoding (MedLEE), on nursing narratives. MedLEE extracted 490 concepts from narrative text in a sample of 553 oncology nursing process notes. The most frequently monitored and recorded signs and symptoms were related to chemotherapy care, such as adverse reactions, shortness of breath, nausea, pain, and bleeding. In terms of nursing interventions, chemotherapy, blood culture, medication, and blood transfusion were commonly recorded in free text. NLP may provide a feasible approach to extract data related to patient safety/quality measures and nursing outcomes by capturing nursing concepts that are not recorded through structured data entry. For better NLP performance in the domain of nursing, additional nursing terms and abbreviations must be added to MedLEE's lexicon.

The terminal cancer patients increase needs for hospice care day by day. A new hospice consulting system has been developed in Taiwan to provide options for terminal cancer patients in choosing a suitable post-acute hospice care while a combined hospice care system is also given by the consulting team in the acute wards. Hereinafter is our report. From March 2005 to January 2006, 313 terminal cancer patients were analysed. These patients had signed consent forms for palliative treatment and had received consultations from the new hospice consulting system. Multivariate analysis showed that the home care patients had better performance status (P = 0.012), less shortness of breath (P = 0.006), less limbs swelling (P = 0.043), less flatulency (P = 0.000) and less constipation (P = 0.018). Among the 162 patients with regular follow-up, the symptoms/signs were significantly improved after intervention of consulting team in pain (P = 0.000), shortness of breath (P = 0.000), difficulty in sleeping (P = 0.002), nausea (P = 0.004), constipation (P = 0.008), changes in skin (P = 0.024) and adoption (P = 0.000). This new system had significant improvement in the terminal cancer patients' symptoms/signs control in acute wards and could contribute to the care quality of home care patients.

Complaints of health symptoms from ambient odors have become more frequent in communities with confined animal facilities, wastewater treatment plants, and biosolids recycling operations. The most frequently reported health complaints include eye, nose, and throat irritation, headache, nausea, diarrhea, hoarseness, sore throat, cough, chest tightness, nasal congestion, palpitations, shortness of breath, stress, drowsiness, and alterations in mood. Typically, these symptoms occur at the time of exposure and remit after a short period of time. However, for sensitive individuals such as asthmatic patients, exposure to odors may induce health symptoms that persist for longer periods of time as well as aggravate existing medical conditions. A workshop was held at Duke University on April 16-17, 1998 cosponsored by Duke University, the Environmental Protection Agency (EPA). and National Institute on Deafness and Other Communication Disorders (NIDCD) to assess the current state of knowledge regarding the health effects of ambient odors. This report summarizes the conclusions from the Workshop regarding the potential mechanisms responsible for health symptoms from ambient odors. Methods for validation of health symptoms, presence of odor, and efficacy of odor management techniques are described as well.
