Using metronidazole in oral dosages of 1.5 to 2 g daily, we treated 13 adults who had anaerobic pleuropulmonary infections, including 11 with lung abscess, one with necrotizing pneumonia, and one with thoracic empyema. Five patients (four with lung abscess and one with necrotizing pneumonia) were cured. The lung abscesses of 5 patients did not respond. For 3 patients (one with epigastric distress who refused metronidazole, one with undrained empyema, and one who died while receiving metronidazole), therapy could not be evaluated. Side effects included leukopenia (2 patients), leukopenia and neutropenia (one), neutropenia (one), dark urine (two), bitter taste (two), and epigastric distress (one). In light of our findings, metronidazole is not uniformly effective in the treatment of anaerobic pleuropulmonary infections.

In the first evaluation of an uncontrolled multicenter study on inhalative pentamidine prophylaxis (300 mg pentamidine-isethionate monthly) of pneumocystis carinii pneumonia in immunocompromised patients, 48 patients (all 48 patients HIV1-infected, 36 without preceding pneumocystis carinii pneumonia (primary prophylaxis), twelve after pneumocystis carinii pneumonia (secondary prophylaxis); age 20 to 68 years (median 38); 45 male, two female, one unknown; 22 patients AIDS) were observed for 0 to 8.5 months (mean 4 +/- 2 months, intended observation time twelve months). No proven pneumocystis carinii pneumonia was found in the observed patients. One patient was treated with cotrimoxazole because of a suggested pneumocystis carinii pneumonia-relapse, which could not be proven. Out of seven (14.6%) patients, whose therapy was discontinued, three patients died, three refused further therapy, one patient had a relapse of a cerebral toxoplasmosis. Six patients (12.5%) reported adverse reactions (cough, metallic or bitter taste, slight nausea). New opportunistic infections appeared in four patients (8.3%).

Eligible patients were randomised in this multicentre, randomised, double-blind, double-dummy parallel-group study in a ratio of 1:1 to either gatifloxacin 400 mg once-daily for 5-14 days plus matching placebo, or clarithromycin 500 mg twice-daily for 5-14 days. The primary outcome measure was clinical response (clinical cure plus improvement) at the end of treatment. Secondary endpoints were clinical response at end of study, clinical cure at end of treatment and end of study, bacteriological response at end of treatment and end of study, and treatment duration. The overall clinical response was similar in the two treatment groups, with 92.2% of gatifloxacin-treated patients cured or improved at the end of treatment, compared with 93.1% of those receiving clarithromycin. Corresponding bacteriological response rates (eradication plus presumed eradication) were 96.7% and 87.5%, respectively. The study drugs were well-tolerated, with nausea (gatifloxacin) and bitter taste (clarithromycin) being the only treatment-related adverse events with a frequency of > 5%. No patients experienced phototoxicity, hepatic or renal dysfunction, tendonitis or crystalluria. Oral gatifloxacin 400 mg once-daily appeared to be a safe and effective alternative to clarithromycin in the treatment of community-acquired pneumonia.

Gastroesophageal reflux disease (GERD) may cause, trigger or exacerbate many pulmonary diseases. The physiological link between GERD and pulmonary disease has been extensively studied in chronic cough and asthma. A primary care physician often encounters patients with extra esophageal manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system; noncardiac chest pain; and ear, nose and throat disorders. Local irritation in the esophagus can cause symptoms that vary from indigestion, like chest discomfort and abdominal pain, to coughing and wheezing. If the gastric acid reaches the back of the throat, it may cause a bitter taste in the mouth and/or aspiration of the gastric acid into the lungs. The acid can cause throat irritation, postnasal drip and hoarseness, as well as recurrent cough, chest congestion and lung inflammation leading to asthma and/or bronchitis/ pneumonia. This clinical review examines the potential pathophysiological mechanisms of pulmonary manifestations of GERD. It also reviews relevant clinical information concerning GERD-related chronic cough and asthma. Finally, a potential management strategy for GERD in pulmonary patients is discussed.

Approximately 1 percent of primary care office visits are for chest pain, and 1.5 percent of these patients will have unstable angina or acute myocardial infarction. The initial goal in patients presenting with chest pain is to determine if the patient needs to be referred for further testing to rule in or out acute coronary syndrome and myocardial infarction. The physician should consider patient characteristics and risk factors to help determine initial risk. Twelve-lead electrocardiography is typically the test of choice when looking for ST segment changes, new-onset left bundle branch block, presence of Q waves, and new-onset T wave inversions. For persons in whom the suspicion for ischemia is lower, other diagnoses to consider include chest wall pain/costochondritis (localized pain reproducible by palpation), gastroesophageal reflux disease (burning retrosternal pain, acid regurgitation, and a sour or bitter taste in the mouth), and panic disorder/anxiety state. Other less common but important diagnostic considerations include pneumonia (fever, egophony, and dullness to percussion), heart failure, pulmonary embolism (consider using the Wells criteria), acute pericarditis, and acute thoracic aortic dissection (acute chest or back pain with a pulse differential in the upper extremities). Persons with a higher likelihood of acute coronary syndrome should be referred to the emergency department or hospital.
