Abstract: In the assessment of community-acquired pneumonia, an effort should be made to identify the causal pathogen, since this may permit more focused treatment. However, diagnostic testing should not delay appropriate empiric therapy. The selection of empiric therapy can be guided by a patient stratification system that is based on the severity of illness and underlying risk factors for specific pathogens. For example, outpatients who do not have underlying cardiopulmonary disease or other risk factors can be given azithromycin, clarithromycin, or doxycycline. Higher-risk outpatients should be given a ß-lactam antibiotic plus azithromycin, clarithromycin, or doxycycline, or monotherapy with a fluoroquinolone. If the patient fails to respond to therapy, it may be necessary to do bronchoscopy; CT of the chest; or serologic testing for Legionella species, Mycoplasma pneumoniae, viruses, or other pathogens.

Most pain in or around the oral cavity is attributable to tooth or mucosal pathology. However, tooth or mucosal pain may also be caused by a variety of other conditions, including brain pathology; vascular inflammatory and cardiac disease; jaw infection or neoplasm; neuropathic abnormality not associated with central pathology; pathology in the neck and thoracic region; myofascial and temporomandibular joint pathology; and disease of the ear, eye, or nose, or of the paranasal sinuses, lymph nodes, and salivary glands. Accurate diagnosis is facilitated when the features of pain presentation in this region are understood.
