Pseudomembranous necrotizing tracheitis is a rare cause of life threatening central airway obstruction (CAO). Patients present with hoarseness, cough, dyspnea, wheezes, stridor and occasionally respiratory failure. Diagnosis requires high index of suspicion and should be confirmed with a comprehensive bronchoscopic examination and biopsy. For patients with signs and symptoms of airway obstruction, a therapeutic rigid bronchoscopy with mechanical debridement is recommended. We present a rare case of necrotizing tracheitis secondary to Corynebacterium species causing life threatening airway obstruction in an adult.

OBJECTIVE:

To evaluate the postoperative outcome of patients with pharyngoesophageal diverticulum submitted to surgical and endoscopic treatments.

METHODS:

We retrospectively analyzed 36 patients with pharyngo-esophageal diverticulum treated at the Hospital of the Medical School of Botucatu - UNESP. Patients were divided into two groups, depending on the treatment: group 1 (n = 24): diverticulectomy associated myotomy through a left cervicotomy; group 2 (n = 12): endoscopic diverticulostomy with linear stapler.

RESULTS:

Operative mortality was zero in both groups. Early complications: group 1- two patients developed cervical fistula and two, hoarseness; group 2 - none. Late complications: group 1 - none; group 2: recurrence of dysphagia in four patients (p = .01). Mean follow-up was 33 months for group 1 and 28 months for group 2.

CONCLUSION:

Both procedures were effective in remission of dysphagia. Surgical treatment showed superiority to endoscopy, with resolution of dysphagia with a single procedure. Endoscopic treatment should be reserved for the elderly and those with comorbidities.

: Thyroid surgery for benign diseases mainly involves young women, and thus, cosmetic considerations have motivated the development of "no scar to the neck" procedures. Endoscopic techniques are often strenuous, and therefore, discouraging to adopt. However, the recent incorporation of robotic technology proposes a feasible, safe, extracervical approach that alleviates most of the technical difficulties associated with endoscopy. Here, the authors present a series of robotic thyroidectomies performed to treat benign thyroid diseases and detail the key issues of initial patient selection.: From November 2007 to December 2010, 44 patients with benign thyroid disease were operated upon using a robotic procedure. Indications were follicular/Hürthle cell lesions smaller than 5 cm, nodules with an indefinite/suspicious cytology, or Graves disease. All patients underwent robotic gasless, transaxillary thyroidectomy using the da Vinci S system.: Thirty-nine of the 44 patients were women, and the overall mean age was 38.2 years (range, 16 to 60 y). The most common pathology was adenomatous hyperplasia (20 lesions) followed by follicular adenoma (10 lesions). Seven patients had Graves disease. The mean tumor size was 1.68 cm (range, 0.3 to 5 cm). Thirty-nine patients underwent less than total thyroidectomy and 5 underwent total or near total thyroidectomy. The mean total operative time was 129.8 minutes (range, 75 to 242 min) and the mean duration of postoperative hospital stay was 3.1 days (range, 2 to 5 d). Postoperative complications were 1 transient hoarseness, 1 transient hypocalcemia, and 1 permanent recurrent laryngeal nerve injury.: Robotic thyroidectomy, although novel and sophisticated, has already been used to treat over 4000 thyroid cancer patients in Korea. Female patients with a small to average build, with a follicular lesion and concerned about neck scarring, seem to be the best candidates. Patients with small suspicious nodules without severe thyroiditis are also a rational choice. In contrast, patients with Graves disease should be reserved, unless significant experience has been gained.

Laryngopharyngeal reflux (LPR) disease has many symptoms such as globus pharyngeus, excessive throat clearing and hoarseness. The aim of this study was to investigate the effect of stellate ganglion block (SGB) in addition to proton pump inhibitors (PPI) on LPR.Fifty patients complaining of more than 3 typical LPR symptoms for over 3 months were enrolled in the study. The P group took PPI for 8 weeks. The SP group took PPI and interwent a series of 8 SGB procedure once a week during the period of treatment. The blocks were performed one at a time unilaterally on the right and left stellate ganglions by injecting 1% mepivacaine 6 ml. We evaluated the reflux symptom index (RSI) before treatment and following 4 weeks and 8 weeks of treatment in both groups.After 4 weeks of treatment, the RSI of the P group decreased, but not significantly, to 16.6 ± 6.8 compared with the baseline value of 19.2 ± 2.7 (P = 0.093), whereas the RSI of the SP group decreased significantly to 9.8 ± 3.3 compared with the baseline value of 19.0 ± 4.7 (P = 0.000). After 8 weeks of treatment, the RSI of the P group decreased significantly to 13.7 ± 6.7 (P = 0.001) and the RSI of the SP group also decreased significantly to 7.7 ± 3.4 (P = 0.000). There were significant differences in the RSI between the two groups after 4 weeks (P = 0.000) and 8 weeks (P = 0.001) of treatment.The symptoms of LPR improved earlier when PPI therapy was combined with SGB compared with PPI therapy alone.

We report here a case of cervical carotid artery aneurysm. This 37-year-old male suffered from acute neck swelling when he was taking lunch after physical work. Ultrasonography demonstrated a cervical pseudoaneurysm and a jet flow, which was blowing into the dome from the carotid artery. Angiogram revealed an aneurysm with a diameter of 3cm at the bifurcation of the common carotid artery. Coil embolization using double-catheter technique was performed and complete occlusion of the aneurysm was obtained without any complications. The patient returned to his normal life. Cervical carotid artery aneurysms are rare and they induce pain by swelling in the neck, hoarseness, swallowing disturbance, hemorrhage, and cerebral ischemia due to embolism. In case of a cervical carotid artery aneurysm, safe and effective treatments are required and endovascular treatment should be considered. Although stent-assisted coil embolization or covered-stent placement were reported as an effective treatment for cervical aneurysms, coil embolization without using a stent was performed in this particular patient who is a young, blue-collar worker because the avoidance of long-term anti-platelet therapy was desirable. Preoperative evaluation is important to select adequate treatment.

Extraskeletal Ewing's sarcoma arising in the head and neck region is an extremely rare malignant neoplasm. We describe the unusual case of a tumor originating in the larynx of a 68-year-old male with hoarseness and occasional aphonia. We report successful treatment with sequential chemo- and radiotherapy. Complete regression and larynx preservation with voice function recovery was achieved. To our knowledge, this is the first report of this type of tumor in the larynx with cartilage invasion that documents the effectiveness of radiotherapy as an alternative to surgical management. At present, after 30 months of follow-up, the patient is free of tumor relapse and in very good condition.

Benign nerve cell tumours have been given various names like schwannoma, neurilemmoma, neurinoma, neurofibroma, spindle cell tumours etc. Extra cranial head and neck schwannomas usually present as solitary and well-demarcated lesions. The lesion can cause secondary symptoms, such as nasal obstruction, dysphasia, and hoarseness, depending upon the location of the lesion. Fine needle aspiration cytology, CT scans, and MRI may be of limited help in the diagnosis of schwannomas. The treatment is complete surgical excision of the benign tumour and postoperative histopathological examination establishes the final diagnosis.

Laryngeal leiomyosarcoma is an exceedingly rare malignant tumour, with fewer than 50 reported cases in scientific literature. Diagnosis is based on immunohistochemistry, supplemented with ultrastructural studies, if required. It is aggressive and associated with variable survival outcomes. A 63-year-old man presented with hoarseness for 7 months and breathlessness for 3 months. Imaging showed a well-defined 3 cm glottic mass. Total laryngectomy was performed. The histopathological examination showed features of leiomyosarcoma. The index case has been presented owing to its rarity, variable clinical manifestations and diagnostic dilemmas and to stress upon the importance of ancillary techniques for confirmation.

The benign lesions of esophagus constitutes small part of all esophageal tumors and among them giant esophageal polyps are exceptionally rarely reported. The authors present the uncommon case of pedunculated giant fibrovascular polyp (lenght 12cm and diameter 2cm) in the esophagus in a 79-years-old woman who was admitted to our department because of hoarseness, throat discomfort during swallowing and endoral tumor regurgitation during cough. The polyp was removed by minimally invasive approach by endoscopic procedure which was particularly important in our patient because of her advanced age. No recurrence was observed during follow-up.
