Appendicitis is a common cause of abdominal pain for which prompt diagnosis is rewarded by a marked decrease in morbidity and mortality. The history and physical examination are at least as accurate as any laboratory modality in diagnosing or excluding appendicitis. Those signs and symptoms most helpful in diagnosing or excluding appendicitis are reviewed. The presence of a positive psoas sign, fever, or migratory pain to the right lower quadrant suggests an increased likelihood of appendicitis. Conversely, the presence of vomiting before pain makes appendicitis unlikely. The lack of the classic migration of pain, right lower quadrant pain, guarding, or fever makes appendicitis less likely. This article reviews the literature evaluating the operating characteristics of the most useful elements of the history and physical examination for the diagnosis of appendicitis.

On October 9, 2001, a letter containing anthrax spores was mailed from New Jersey to Washington, DC. The letter was processed at a major postal facility in Washington, DC, and opened in the Senate's Hart Office Building on October 15. Between October 19 and October 26, there were 5 cases of inhalational anthrax among postal workers who were employed at that major facility or who handled bulk mail originating from that facility. The cases of 2 postal workers who died of inhalational anthrax are reported here. Both patients had nonspecific prodromal illnesses. One patient developed predominantly gastrointestinal symptoms, including nausea, vomiting, and abdominal pain. The other patient had a "flulike" illness associated with myalgias and malaise. Both patients ultimately developed dyspnea, retrosternal chest pressure, and respiratory failure requiring mechanical ventilation. Leukocytosis and hemoconcentration were noted in both cases prior to death. Both patients had evidence of mediastinitis and extensive pulmonary infiltrates late in their course of illness. The durations of illness were 7 days and 5 days from onset of symptoms to death; both patients died within 24 hours of hospitalization. Without a clinician's high index of suspicion, the diagnosis of inhalational anthrax is difficult during nonspecific prodromal illness. Clinicians have an urgent need for prompt communication of vital epidemiologic information that could focus their diagnostic evaluation. Rapid diagnostic assays to distinguish more common infectious processes from agents of bioterrorism also could improve management strategies.

An experimental drug - bromocriptine - apparently restores menses and suppresses prolactin production in women with amenorrhea and galactorrhea. Side effects such as nausea, vomiting, lightheadedness, and mild ankle edema usually abate after the first few weeks of therapy. In a study of 13 women with elevated prolactin levels who were treated with 2.5 mg of bromocriptone orally twice a day for up to 24 weeks, galactorrhea diminished markedly in all the patients. Only 5 had complete cessation of galactorrhea. Galactorrhea returned in 11 patients when they stopped taking the drug. Menses were restored in 10 of the women after 3-10 1/2 weeks of treatment. 3 women became pregnant before the resumption of menses. The degree of prolactin suppression (reduced to less than 20 ng/ml in a patient) failed to correlate well with early or late resumption of menses or conception.

OBJECTIVE To identify predictors of persistent concussion symptoms (PCS) in children following concussion. DATA SOURCES We searched MEDLINE, Embase, and the Cochrane Library to April 2012. STUDY SELECTION A systematic review of the literature to identify prognosticators of PCS following pediatric concussion was conducted. Studies evaluating patients aged 2 years to 18 years with PCS were eligible. MAIN OUTCOME MEASURES The association of clinically available factors with PCS development. RESULTS A literature search yielded 824 records; 561 remained after removal of duplicates. Fifteen studies were included in descriptive analysis; heterogeneity precluded a meta-analysis. Larger prospective studies concluded that the risk for PCS was increased in older children with loss of consciousness, headache, and/or nausea/vomiting. Smaller studies noted that initial dizziness may predict PCS. Patients with premorbid conditions (eg, previous head injury, learning difficulties, or behavioral problems) may also have increased risk. CONCLUSIONS Minimal, and at times contradictory, evidence exists to associate clinically available factors with eventual development of PCS in children. Future trials must be adequately powered to determine which variables best predict the time to full symptom resolution. Expert consensus should delineate which postconcussion assessment measures are preferred to reduce heterogeneity going forward. Research to improve care for the epidemic of pediatric concussion depends on early identification of those most in need of intervention.
