Anaplastic Thyroid Carcinoma; Thyroid; Cancer
Anaplastic thyroid carcinoma (ATC) is a poorly differentiated thyroid cancer. It cannot uptake iodine or synthesis thyroglobulin. The incidence is low; about 2% – 5% of thyroid cancer. The peak age incidence is 60 – 70 years and it is more common in females (55% – 77% of all patients). In recent years, the incidence has declined; however, it may be higher in areas of endemic goiter. ATC may occur with a coexisting carcinoma and may represent transformation of a well-differentiated thyroid cancer. Patients typically present with a rapidly growing anterior neck mass and aggressive symptoms. The most reliable tool in detecting thyroid malignancies is fine-needle aspiration cytology (FNAC). Sensitivity of FNAC for thyroid malignancy ranged from 61% to 97.7%. Fine-needle aspiration can diagnose ATC by the demonstration of spindled or giant cells, bizarre neoplastic cells that may be multinucleated, or atypical cells with high mitotic activity. A syncytial pattern is the predominant cellular pattern of anaplastic thyroid carcinoma. Other laboratory tests, including tumor markers (cytokeratin, vimentin, and carcinoembryogenic antigen) are helpful in diagnosis and follow-up of the patients. Multimodality therapy (surgery, external beam radiation, and chemotherapy) is the recommended treatment and it seems to have slightly improved outcomes. The prognosis is not as bad in younger patients with smaller tumors. The most common cause of death is lung metastasis. The mean survival time is less than 6 months from the time of diagnosis. The prompt diagnosis and aggressive treatment are essential modality to achieve optimal outcomes.

Background: Rhinoplasty is the most common operation performed by our facial plastic surgery unit. Recognition of patients with psychological problems which may result in an unfavourable post-operative outcome is essential. The objective of this study was to evaluate the psychological status of patients seeking rhinoplasty, compared with the general population.
Methods: We prospectively collected the data from patients who requested rhinoplasty in Srinagarind hospital, Thailand and controls. We used the general health questionnaire-28 (GHQ-28) for psychological problems detection.
Results: We included a total of 196 participants, 98 in study group and 98 in control group. The study group has a 5.5 times (95% CI 1.25 to 24.17, P = 0.01) higher risk for poor mental status more than control group.
Conclusions: The patients seeking rhinoplasty group were more likely to have psychological problems when compared with the control group. Surgeons should be aware of the patient’s psychological status before performing the operation.
Background: The essential factor for diagnosis and treatment of diseases in head and neck endoscopy is the visibility of the image. An anti-fogging agent can reduce this problem by minimizing surface tension to prevent the condensation of water in the form of small droplets on a surface. There is no report on the use of hibiscrub? or baby shampoo to reduce fogging in the literature. The objective of this study was to compare the efficacy between commercial anti-fogging agent, hibiscrub? and baby shampoo to reduce fogging for the use in head and neck endoscopy. Methods: The study was conducted at the Department of Otorhinolaryngology, Faculty of Medicine, Khon Kaen University in August 2010. Commercial anti-fogging agent, baby shampoo and hibiscrub? were applied on rigid endoscope lens before putting them into a mist generator. The images were taken at baseline, 15 seconds, 30 seconds and 1 minute. The images? identifiers were removed before they were sent to two evaluators. A visual analogue scale (VAS) was used to rate the image quality from 0 to 10. Results: The difference in mean VAS score between anti-fogging agent, baby shampoo and hibiscrub? versus no agent were 5.46, 4.45 and 2.1 respectively. The commercial anti-fogging agent and baby shampoo had most protective benefit and performed significantly better than no agent (P < 0.05). Conclusions: Baby shampoo is an effective agent to prevent fogging during head and neck endoscopy and compares favourably with commercial anti-fogging agent.

INTRODUCTION:?Tracheostomy is a common airway procedure for life support. The fracture of the tracheostomy tube is a rare complication. We report a case of a 14-year-old boy whose fractured stainless steel tracheostomy tube dislodged into the tracheobronchial tree. We include a literature review and proposed recommendations for tracheostomy care.
CASE PRESENTATION:?A 14-year-old Thai boy who had a stainless steel tracheostomy tube presented with a complaint of intermittent cough for 2 months. During tracheostomy tube cleaning, his parents found that the inner tube was missing. A chest X-ray revealed a metallic density foreign body in his right main bronchus. He underwent bronchoscopic removal of the inner tracheostomy tube and was discharged without further complications.
CONCLUSION:?A fractured tracheostomy tube is a rare complication. Appropriate cleaning and scheduled replacement of the tracheostomy tube may prevent this complication

BACKGROUND: An acute complication of thyroidectomy is fatal hematoma, which can produce an upper airway obstruction needing immediate intubation or tracheostomy. After neck surgery, we usually apply a pressure dressing with a non-woven, adhesive fabric to reduce bleeding and fluid collection at the operative bed. We conducted a prospective, randomized, controlled study to evaluate a pressure vs. a non-pressure dressing after thyroid surgery by monitoring blood and serum in the operative bed. METHODS: We studied 108 patients who underwent 116 thyroid surgeries at Srinagarind Hospital, Khon Kaen University, between December 2006 and September 2007. The patients were randomized to either the pressure dressing or non-pressure dressing group. Ultrasound of the neck was performed 24 +/- 3 hours after surgery. The volume of fluid collection in the operative bed was calculated. All patients were observed for any post-operative respiratory distress, wound complications, tingling sensation or tetany. RESULTS: The distributions of age, sex, surgical indications and approaches were similar between the two groups. There was no statistically significant difference in the volume of fluid collection in the operative bed (p = 0.150) and the collected drained content (p = 0.798). The average time a drain was retained was 3 days. One patient in the pressure dressing group suffered cutaneous bruising while one patient in the non-pressure dressing group developed immediate hemorrhage after the skin sutures. CONCLUSION: Pressure dressing after thyroidectomy does not have any significant impact on decreasing fluid collection at the operative bed. The use of pressure dressing after thyroidectomy may not therefore be justified. TRIAL REGISTRATION: NCT00400465, ISRCTN52660978
