Does Shamblin's classification predict postoperative morbidity in carotid body tumors? A proposal to modify Shamblin's classification.

The objective of this study was to analyze the possible correlation between Shamblin's classification and post-surgical morbidity in the treatment of carotid body tumors (CBTs). Seventy-two patients with carotid body tumors were seen over a 22-year period. Twenty-three patients were excluded as they did not comply with the criteria of the objectives.

[Dysphagia secondary to lingual thyroid].

Background: Lingual thyroid is a rare developmental anomaly originating from aberrant embryogenesis during descent of the gland from its site of origin, the foramen caecum, to its eutopic location.

Objective: We present the case of a 30-year-old female with a history of dysphagia and pharyngeal foreign body sensation over the past 12 months, associated with hypothyroidism.

Methods: Diagnostic and therapeutic approaches are discussed.

[Internal carotid artery reconstruction with transposition of external carotid artery in carotid body tumor resection].

The current treatment of Shamblin's class III carotid body tumors includes a variety of reconstructive techniques for the internal carotid artery, ranging from angioplasty to the use of various grafts such as autologous saphenous vein or synthetic shunts. We present the case of a 56-year-old female patient with a carotid body tumor. The diagnosis and therapeutic approach is discussed, as well as the surgical technique and postoperative outcome.

[Total glossectomy with larynx preservation and reconstruction with rectus abdominis free flap].

Objective: Our objective was to show the complexity and series of events needed to perform the reconstruction with rectus abdominis free flap to achieve an adequate rehabilitation for patients submitted to total glossectomy with larynx preservation due to advanced tongue carcinoma.

Methods: Two patients with stage IV carcinoma of the tongue were treated with surgery--one as primary treatment, the other for recurrence. Patients underwent total glossectomy, bilateral radical neck dissection, gastrostomy, tracheostomy, and reconstruction with rectus abdominis free flap.

Carotid body tumors: review of a 20-year experience.

Carotid body tumors (CBT) are a rare entity that should be considered in evaluating every lateral neck mass. The objective of the study was to compare demographic data, complications and evolution of patients treated at our institution. A retrospective study was made of 66 patients with 69 CBT that were treated at our institution between 1982 and 2002.

[Appendicitis following esophagogastroduodenal study: report of a case].

Retention of barium within appendix following a gastrointestinal tract study may predispose in rare instances to narrowing of appendiceal lumen, thus contributing to development of acute appendicitis. We present the case of a 42-year-old woman in whom this sequence of events was recognized who presented with clinical signs of acute appendicitis 9 days after barium swallow test was performed. Patients must be informed increased chance for development of appendicitis in these cases and be instructed to recognize early symptoms.
