New research has shown that the incidence of success of replanted avulsed teeth can be greatly increased by differentially diagnosing and treating them according to the length of extraoral time and the physiological width of the apical foramen. A specific treatment regimen has been presented that will give the physician the information necessary to maximize the success of replanted avulsed teeth that may be seen.

The objective of this study was to examine the use of limited, goal-directed, two-dimensional ultrasound studies performed by emergency physicians and to assess the frequency, variety, and accuracy of their readings. A 1-year prospective study was performed by using an emergency department (ED) ultrasound machine with a 3.5-mHz mechanical oscillating sector transducer and a 5.0-mHz vaginal transducer. In a series of proctoring sessions, radiologists trained emergency physicians to do limited, goal-directed ultrasonography. ⋯ Eleven categories of ultrasound use were reported. The three studies most commonly performed were for gallbladder disease (53%), intrauterine pregnancy (28%), and abdominal aortic aneurysms (7%). Accuracy of ED gallbladder ultrasonograms for 65 patients showed a sensitivity of .86, specificity of .97, PPV of .97, and NPV of .85.(ABSTRACT TRUNCATED AT 250 WORDS)

Review Case Reports
Imipramine-provoked paradoxical pheochromocytoma crisis: a case of cardiogenic shock.
The dramatic presentation of pheochromocytoma in crisis is uncommon and is classically associated with a state of hemodynamic and sympathetic hyperactivity. The case of a 35-year-old man with an occult pheochromocytoma presenting with hypotension and cardiogenic shock shortly after beginning imipramine therapy is presented. Retrospectively, there was a history of emergency department, inpatient, and outpatient evaluation of symptoms likely to be related to an occult pheochromocytoma. ⋯ Shortly after admission the patient's occult pheochromocytoma was discovered and subsequently specific therapy was initiated. The patient's symptoms resolved after surgical resection of the tumor, and he was ultimately discharged without signs of congestive heart failure. The clinical pathophysiology of cardiomyopathy secondary to pheochromocytoma, and possible mechanisms of pharmacological interactions with tricyclic antidepressants are discussed.

In a retrospective case review of inpatient and emergency department (ED) records during a 55-month period, 155 hospitalizations for Kawasaki syndrome (KS) were identified, of which 44 were seen in the ED. In 16 cases, KS was already suspected by their private physicians and confirmed in the ED by a KS specialist. In the remaining 28, patients presented initially to the ED. ⋯ In four instances, patients were hospitalized for other reasons. In all cases in which the diagnosis of KS was not made in the ED, viral infections or sepsis were suspected. One child presented to the ED in respiratory arrest and severe bradycardia.

Review Case Reports
Midgut volvulus: an unusual case of adolescent abdominal pain.
Rotational gut abnormalities are generally considered a disease process of the neonatal and pediatric populations. However, they may first become manifest in teenagers and adults, often with disastrous outcomes. ⋯ At surgery, he was found to have a midgut volvulus. A differential diagnosis is discussed, as well as an anatomical review and typical symptomatology associated with midgut abnormalities.
