Chronic cough is a common symptom presenting to all clinicians. Every effort should be made to determine the cause(s) of cough because specific therapy has a higher likelihood of success than empiric therapy. Evaluation begins with a complete history, physical examination, routine health screen laboratory testing, chest film, and pulmonary function testing. Further investigation should be guided by the response to treatment of the most likely diagnostic possibilities: postnasal drip, cough-variant asthma, gastroesophageal reflux, chronic bronchitis, bronchiectasis, and ACE inhibitor induced. The majority of each patient's workup can be performed and ordered by the primary care physician.

Refractory cough in a patient with a normal chest X-ray usually falls into one of five categories: drug-induced (especially by ACE inhibitors), secondary to postnasal discharge, gastroesophageal reflux, or hyperactive airway disease, and idiopathic but responsive to nebulized lidocaine. The history may point to the most likely cause, and empiric therapy may confirm the diagnosis.

H1 antihistamines have been shown to have antitussive effects in patients with asthma and postnasal drip. In Japan, no study has been performed to determine whether orally administered oxatomide, H1 antihistamine, can reduce the chronic cough seen in patients with post-upper-airway infection (postinfection). Patients who had chronic cough of more than three weeks' duration and a history of post-upper-airway infection took part in the study. None had any history of nasal disease, gastroesophageal reflux, bronchial asthma, or other chronic pulmonary disease. All patients were non-smokers, and none used ACE inhibitors. They had normal CRP concentrations, peripheral white blood cell and eosinophil counts, serum IgE concentrations, titers of cold agglutinins and antibodies to Mycoplasma pneumoniae, chest roentgenograms, and respiratory function tests. A prospective randomized, open design was used. The effect of one week of treatment with dextromethorphan (D) or with D plus oxatomide (D + O) on the severity of cough, as estimated by cough diary, were examined. Twenty-two patients entered the study, and 20 were eligible for efficacy and side-effect analyses. Nine patients receiving D and 11 receiving D + O completed the protocol. Patients' characteristics before the start of the study, such as severity and duration of cough, and laboratory data, were not significantly different between the two groups. From trial day 5 to 7, improved rates of cough were significantly higher with D + O than with D alone (p < 0.05). Combination therapy with oxatomide and dextromethorphan reduces subjective perception of cough as estimated by cough diary. These results suggest that oxatomide, H1 antihistamine may improve chronic cough in patients with post-upper-airway infection.

The cause can almost always be identified. Postnasal drip syndrome, asthma, or gastroesophageal reflux disease account for most cases. The differential diagnosis also includes ACE inhibitor therapy, pertussis, and, in up to 80% of patients, multiple causes. Response to treatment may offer diagnostic confirmation but can be slow in coming.

Hypertension is a significant and prevalent risk factor for the development of cardiovascular disease and target organ damage. The urgency of treatment of high blood pressure depends on the level of blood pressure elevation and the presence of coexistent risk factors for cardiovascular disease. Likewise, the level to which blood pressure is reduced is not restricted to the definition of high blood pressure but instead depends on the underlying disease. Diabetes and renal insufficiency, for example, require blood pressure goals below those that are traditionally defined. In the absence of contraindications, beta-blockers and diuretics are still recommended as first-line agents for treatment of uncomplicated hypertension. Calcium channel antagonists also may reduce mortality. In patients with diabetes, ACE inhibitors are effective first-line agents in type 1 and type 2 diabetic patients who are hypertensive or have microalbuminuria. ACE inhibitors may be beneficial in patients with nondiabetic renal insufficiency as well. Calcium channel antagonists may have some effect in retarding progression of diabetic nephropathy although a recent trial found a higher incidence of death as a secondary endpoint in hypertensive diabetic patients who were treated with calcium channel antagonists. Beta-blockers seem to be safe and well tolerated in patients with mild to moderate intermittent claudication, although patients with rest pain or limb ischemia have not been studied. Beta-blockers should not be used in patients with asthma. Dihydropyridine calcium channel antagonists are the preferred treatment of hypertension in patients with Raynaud's but should be avoided in patients with severe gastroesophageal reflux disease. NSAIDs, particularly piroxicam and indomethacin, raise mean blood pressure by approximately 5 mm Hg, enough to consider a change of either NSAID or antihypertensive to one that is not as affected by NSAIDs. Cyclosporine A can induce hypertension by its vasoconstrictive effects, particularly on the kidney. Calcium channel antagonists may antagonize this vasoconstriction while allowing the clinician to reduce the dose of cyclosporine A required to achieve its immunosuppressive effect.

Systemic sclerosis is an extremely variable disease in its manifestations and consequently, treatment needs to be individualized depending on the specific problems that each patient has. Limited scleroderma patients have a prolonged duration of Raynaud's phenomenon and puffy fingers before they develop any skin thickening, digital ulcers or gastrointestinal symptoms. They are likely to present with all the classic manifestations of scleroderma. Diffuse scleroderma patients have a much more acute systemic onset with marked whole hand swelling and may initially have only subtle skin thickening. A good understanding of the differences between the natural history of limited and diffuse scleroderma will enable the physician to treat present problems and anticipate future ones more effectively. One should determine which major subset and organ systems are involved before deciding on the appropriate therapy. Advances in organ-specific therapy, particularly calcium channel antagonists in Raynaud's phenomenon, proton pump inhibitors in esophageal reflux, intravenous iloprost and endothelin receptor antagonists in pulmonary hypertension, and ACE inhibitors in renal crisis, have decreased morbidity and mortality in patients with scleroderma. Studies of aggressive therapies to prevent or improve pulmonary fibrosis are in progress. Further clinical experience in wound healing, gastrointestinal malabsorption and physical therapy for loss of motion has helped patients to have a more comfortable life. In recent years, a significant number of controlled clinical trials have been performed and there has been improved understanding of the best way to perform studies and of which patients are most likely to respond to therapy. Penicillamine, methotrexate, photopheresis, relaxin, interferons, and cyclosporine have all been studied in controlled trials with variable outcomes. Although an overall remittive therapy has not yet been determined, new, potentially useful agents are being investigated.

Use of tobacco, moderate to heavy alcohol ingestion, infrequent consumption of raw fruits and vegetables, and low income accounted for more [figure: see text] than 98% of the SCE rates among both African American and white men and for 99% of the excess incidence among African Americans compared to whites in a case-control study in three areas of the United States [14]. Thus, it is likely that declines in the prevalence of smoking and drinking, especially among men, and increased intake of fresh fruits and vegetables may have contributed to the downward incidence and mortality rate trends reported for SCE. In addition, it seems plausible that obesity, GERD, and possibly reductions in H. pylori prevalence have contributed to the upward trends in ACE rates. Reductions in smoking, improved diet, and reductions in H. pylori prevalence probably have contributed to the consistent reductions observed for NGA. Contributing factors are less clear for the rising incidence rates of GCA during the 1970s and 1980s. These incidence rates have not continued to rise in recent years.

Chronic cough is a common problem in patients who visit physicians. The three most common causes of persistence cough in nonsmokers who were not taking an ACE inhibitor and who had a normal or stable chest radiograph are: postnasal drip, asthma and gastroesophageal reflux. After a viral upper respiratory infection, it takes sometimes seven weeks for bronchial airway hyperreactivity to return to normal. By using a standard protocol, 95 percent of patients with chronic cough can be managed successfully but in some cases it may take even five months or more to determine a diagnosis and effective treatment.

Postnasal drip, asthma and gastroesophageal reflux disease are the underlying causes in almost 90% of cases with chronic cough. Causal treatment is successful in the majority of patients, although in the event of a long-standing cough, it might need to be continued over several weeks. Smoking complicates the identification of cough as a clinical early symptom of an underlying tumor. Cardiac causes are rare, and in most cases are due to the use of ACE-inhibitors. Cough may be triggered by a variety of causes and the therapeutic palette must include several spectra. Since the individual causes often cannot be unequivocally identified, it may be necessary to take a polypragmatic therapeutic approach targeting the three most common causes simultaneously for 7-10 days.

Esophageal cancer remains an important public health problem worldwide. Understanding and preventing the occurrence of this cancer are complicated by the fact that the 2 major histologic types, squamous cell carcinoma (SCC) and adenocarcinoma (ACE), differ substantially in their underlying patterns of incidence and key etiologic factors. The main characteristic that they share is a high mortality rate. Surveillance, Epidemiology, and End Results data for the United States show a 30% drop in incidence of SCC between 1973 and 2002, with declines greatest in black males, although incidence in this group remains high compared with other groups. Incidence of ACE has increased 4-fold over the same period, with a nearly 5-fold increase in white males. Alcohol and smoking are major, established risk factors for SCC. Gastroesophageal reflux disease is consistently associated with increased risk of ACE, whereas infection with Helicobacter pylori may reduce its incidence. Increasing body mass index is also strongly associated with ACE risk while showing no association or an inverse relationship with SCC. Diet affects both types of esophageal cancer, with a higher intake of fruits and vegetables associated with reduced incidence. Aspirin and other nonsteroidal antiinflammatory drugs are currently the most promising chemoprevention candidates for both cancer types. Lifestyle changes, such as weight loss and exercise, are additional ways in which the incidence of ACE might be reduced.
