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.
ABSTRACT: A number of nondental conditions may cause significant oral pain. Pain associated with temporal arteritis is localized to the maxillary posterior teeth, the maxilla, or the frontal-temple region. This pain is often associated with exquisite tenderness of the scalp and face. The pain of trigeminal neuralgia is typically felt in the anterior maxillary or mandibular anterior teeth; it radiates along the mandible toward or into the ear on the ipsilateral side of the trigger. Pain may remit for months or years but is often severe when it recurs. Burning mouth syndrome preferentially affects postmenopausal women older than 50 years; one half to two thirds of patients experience spontaneous remission within 6 to 7 years, with or without treatment. The pain of postherpetic neuralgia is unilateral and restricted to the affected dermatome; it may be aggravated by mechanical contact or chewing.

Abstract: Acute chest syndrome (ACS) is one of the most common causes of death and hospitalization among patients with a sickle hemoglobinopathy. The clinical presentation is characterized by the appearance of a new infiltrate on a chest radiograph, with 1 or more new symptoms, including fever, cough, chest pain, and dyspnea. Additional findings include leukocytosis, hypoxemia, and auscultatory signs of consolidation. The differential diagnosis includes pneumonia, pulmonary infarction, fat embolism syndrome, pulmonary edema, and bone infarction. Treatment of ACS involves supportive care, empiric antibiotic therapy, and red blood cell transfusion when indicated. The decision of whether to use simple or exchange transfusions depends on the severity of illness and the risk of acute respiratory failure. Currently, hydroxyurea is the only FDA-approved drug designated as a preventive therapy. (J Respir Dis. 2005;26(12):529-534)
