Respiratory symptoms are a common cause of distress in patients with advanced cancer. Optimal palliative therapy requires careful assessment and the appropriate use of symptomatic measures in conjunction with specific antitumor treatments. The etiology and management of the three major respiratory symptoms, dyspnea, cough and hemoptysis, are described. The indications for antitumor treatments and surgical procedures are briefly outlined, and symptomatic treatments, including drug and nondrug measures, are discussed in detail.

Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

Respiratory symptoms are rare manifestations of ulcerative colitis as well as intestinal manifestations in Wegener granulomatosis. We report the case of a 17-year old man previously diagnosed as having ulcerative colitis who presented with diffuse thoracic pain. Hypermetabolic pulmonary nodules were discovered at the positron emission tomographic scan. Necrotizing granulomatous vasculitis was demonstrated at lung biopsy. In this paper, we describe the association between pulmonary nodules and ulcerative colitis and we discuss the possibility of an overlap syndrome between ulcerative colitis and Wegener granulomatosis.

Lung cancer patients visit the emergency room (ER) for cancer-related and -unrelated reasons more often compared to patients with other types of cancer. This results in increased admissions and deaths in the ER. In this study, we retrospectively reviewed the characteristics of lung cancer patients visiting the ER in order to optimize the utilization of emergency medical services and improve the patients' quality of life. Lung cancer patients visiting the ER of a single institution over a 2-year period (2010-2011) were analyzed. The patients' chief complaints and diagnoses at presentation in the ER were classified as cancer-related and -unrelated. Hospital admission, discharge from the ER, hospital mortality and survival of advanced lung cancer patients hospitalized through admission to the ER was surveyed. A total of 113 patients visited the ER 143 times. Seventy visits (49.0%) were cancer-related and 73 (51.0%) were cancer-unrelated. Respiratory symptoms, pain, gastrointestinal and neurological events and fever were the most common cancer-related issues recorded. With the progression of cancer stage, the number of ER visits, admissions, ambulance use and hospital mortalities increased. In visits due to cancer-unrelated issues, including infection, cardiovascular and gastrointestinal diseases, fever was the most common complaint. Emergency admissions of advanced-stage patients for cancer-related issues revealed a significantly shorter median survival time compared to that for patients admitted for cancer-unrelated issues (61 vs. 406 days, respectively; P<0.05). It was observed that outpatients with lung cancer visited the ER for cancer-related and -unrelated reasons with a similar frequency. Therefore, accurate differential diagnosis in the ER is crucial for patients with lung cancer.

As the health status of patients living with multiple chronic conditions declines, these patients experience a variety of symptoms (eg, respiratory, gastrointestinal, psychological symptoms; overall symptoms of decline; and pain). Respiratory symptoms can include dyspnea, cough, and excessive upper respiratory tract secretions. Gastrointestinal symptoms can include nausea and vomiting, constipation, and malignant bowel obstruction. Overall symptoms include anorexia, cachexia, and fatigue. Psychological symptoms may manifest as depression, anxiety, or delirium. For patients with chronic pain and progressive disease, it is important to identify the etiology and type of pain (ie, visceral, somatic, neuropathic) because management differs. An evaluation of total pain should consider the various domains of suffering, including physical, psychological, and spiritual suffering. It is imperative to attempt to identify the underlying causes of the symptoms and address it if possible. It also is important to relieve symptoms using nonpharmacologic and pharmacologic approaches. In patients unable to self-report symptoms, family members and/or caregivers can provide insight into the condition of the patient.
