The usefulness of preoperative dual-phase 99mTc MIBI-scintigraphy and IO-PTH assay in the treatment of secondary and tertiary hyperparathyroidism.

Background: Persistent secondary or tertiary hyperparathyroidism (HPT) results from failure to remove enough hyperfunctioning parathyroid tissue. Ectopically situated parathyroid glands and supernumerary glands make failure more likely. Recurrent HPT after subtotal Ptx is usually due to regrowth of the remaining parathyroid tissue.

Gastric vascular lesion: a case report.

Arteriovenous malformations of the gastrointestinal tract are a known but rare cause of bleeding. Those of the stomach are the rarest if compared with other causes of gastric bleeding. The aetiology is still unknown, but senile age is considered an important cause, as are the degenerative processes connected with old age.

Carcinosarcoma of the esophagogastric junction.

Carcinosarcoma of the esophagus and the stomach are rare neoplasms characterized by the simultaneous presence of carcinomatous and sarcomatous elements. There is no report in the literature of carcinosarcoma of the esophagogastric junction. We present a case of carcinosarcoma of the esophagogastric junction whose unique clinical presentation, surgical issues, morphological and immunohistochemical features makes it quite distinctive from similar cases observed in the esophagus or in the stomach.

Successful surgical management of a delayed pharyngo-esophageal perforation after anterior cervical spine plating.

A case report of a 41-year-old man who had a delayed pharyngo-esophageal perforation without instrumentation failure 7 years after anterior cervical spine plating is presented and the literature on this issue is reviewed. This injury resulted from repetitive friction/traction between the retropharyngo-esophageal wall and the cervical plate construct leading to a pseudodiverticulum and perforation. Successful treatment of the perforation was obtained after surgical repair using a sternocleidomastoid muscle flap.
