Prospective study of ultrasound-guided fine-needle aspiration cytology and sentinel node biopsy in the staging of clinically negative T1 and T2 oral cancer.

Background: The purpose of this study was to compare sentinel node biopsy (SNB) and ultrasound-guided fine-needle aspiration cytology (FNAC) for preoperative evaluation of the N0 neck in T1 to T2 oral cavity squamous cell carcinoma (SCC).

Methods: Fifty-one consecutive patients with T1 to T2 N0 oral cavity SCC were included in this study. Preoperative ultrasound was performed in all patients.

Factors affecting wound complications in head and neck surgery: A prospective study.

Context: Head and neck surgeries are complex. Wound complications are associated with considerable morbidity and can result in delay in the adjuvant treatment. Identification of factors will help in formulating preventive guidelines.

Angiosarcoma of the scalp associated with Xeroderma pigmentosum.

Xeroderma pigmentosum (XP) is a rare autosomal recessive genodermatosis associated with hypersensitivity to ultraviolet light due to defects in Deoxyribonucleic acid (DNA) repair. These patients have more than a 1000-fold increased risk of developing skin cancers. Although multiple cutaneous malignancies are common, the simultaneous occurrence of angiosarcoma and basal cell carcinoma is a rare phenomenon.

Ultrasound-guided botulinum toxin injection: A simple in-office technique to improve tracheoesophageal speech in postlaryngectomy patients.

Background: Pharyngoesophageal spasm is a known entity to cause hypertonic/failed tracheoesophageal speech and is successfully treated by botulinum toxin A injection. However, success of botulinum toxin treatment is based on the accurate localization of the pharyngoesophageal segment.

Methods: A 65-year-old man who had a laryngectomy using voice prosthesis with hypertonic speech underwent ultrasonographic localization of the hypertonic pharyngoesophageal segment.

Management of thyroid cancers.

Thyroid cancers cover a large spectrum of disease with diametrically opposite prognosis. At one end of the spectrum we have the well differentiated cancers which carry an excellent prognosis, while at the other end there is anaplastic cancer with high mortality rates and dismal prognosis. Management of thyroid cancers still has some controversial issues due to lack of randomized controlled trials.
