One hundred seventy consecutive patients with clinical suggestion of acute appendicitis were studied by ultrasound (US) with the examiner using the graded compression technique. In 14 patients, the only US findings consisted of enlarged mesenteric lymph nodes in combination with mural thickening of the terminal ileum. This was consistent with the findings at surgery in four patients and with the results of barium studies in seven patients. In nine of 14 patients, stool cultures were performed, eight of which were positive for Yersinia enterocolitica. None of these 14 patients finally proved to have appendicitis. In a patient with acute pain in the right lower quadrant whose appendix cannot be visualized sonographically and whose US findings consist of enlarged mesenteric lymph nodes and mural thickening of the terminal ileum, the diagnosis is probably mesenteric adenitis and acute terminal ileitis. Appendectomy should be avoided in this condition.

Spontaneous intramural rupture or intramural haematoma of the oesophagus is a rare cause of acute pain in the chest and upper abdomen. Much less ominous than spontaneous complete rupture from which it must be distinguished, it seldom if ever necessitates operation. Five new cases are described and reviewed together with 15 collected from published reports. The dominant symptom of every case was severe and constant retrosternal or epigastric pain; concomitant dysphagia was mentioned in 11 cases. In seven the pain was preceded by or coincided with vomiting. The condition was related to other stresses in three and appeared to be truly spontaneous in 10. In approximately one-third of cases it started suddenly but more often it began as discomfort worsening rapidly. Fourteen patients vomited blood after experiencing pain but only four were given transfusions. In contradistinction to complete rupture, none had surgical emphysema and plain chest radiographs were unremarkable. All had abnormal gastrografin or barium swallows. Intramural haematomas with or without mucosal tears were seen in the 11 cases in which oesophagoscopy was performed. Fifteen patients made rapid and complete recoveries on conservative management. Of the four who did not respond satisfactorily, one had the oesophagus repaired, two had drainage of the mediastinum after failure to find the false lumen at thoracotomy, and one had only an abdominal exploration. The only death in the whole series occurred after a disastrous emergency exploration and subsequent total oesophagectomy.

A 31-year-old woman was referred for the evaluation of persistent lower lip numbness following endodontic treatment of tooth #36. Imaging examinations showed a large amount of radiopaque/hyperdense material spread in an angiographic distribution in the left mandibular body region. Laboratory analyses of tooth #36 and adjacent periapical tissue, surgically extracted in an external Service due to acute pain following endodontic treatment, identified chronic inflammatory reaction and birefringent crystalloid foreign bodies rich in barium and sulphur, leading to the diagnosis of alveolar nerve injury due to accidental extrusion of intracanal dressing material composed of calcium hydroxide [Ca(OH)2 ] paste incorporated with barium sulphate. Clinicians should be aware that Ca(OH)2 when in contact with periapical tissues may lead to persistent toxicities, such as necrosis, pain and paraesthesia. Therefore, injectable Ca(OH)2 systems should be used with caution because they can cause paste extrusion and damage to the lower alveolar nerve.
