    Natl Med J India 2017 Mar-Apr;30(2):76-77
    Radiation Medicine Centre (Bhabha Atomic Research Centre), Tata Memorial Hospital Annexe, Jerbai Wadia Road, Parel, Mumbai, Maharashtra 400012; Homi Bhabha National Institute, Mumbai, Maharashtra, India.
    Malignant involvement of thyroglossal duct cyst is rare, still rarer is the synchronous malignant involvement of the thyroid gland. Although the Sistrunk procedure is often regarded as adequate, controversy exists of the need for an additional total thyroidectomy and radioiodine ablative therapy, the decision of which depends upon the presence of (i) suspicious thyroid gland nodule; (ii) presence of lymphadenopathy; or (iii) a previous history of neck irradiation. We report a 47-year-old woman diagnosed with papillary carcinoma within a recurrent thyroglossal duct cyst with infiltration into surrounding soft tissues and a suspicious thyroid nodule of the left thyroid lobe with no regional lymph node involvement.

    Accounting for tissue heterogeneity in infrared spectroscopic imaging for accurate diagnosis of thyroid carcinoma subtypes.
    Vib Spectrosc 2017 Jul 16;91:77-82. Epub 2016 Sep 16.
    Department of Pathology, University of Illinois at Chicago, 840 S Wood St. 130 CSN, Chicago, IL 60612, USA.
    Fourier transform infrared (FT-IR) microscopy was used to image tissue samples from twenty patients diagnosed with thyroid carcinoma. The spectral data were then used to differentiate between follicular thyroid carcinoma and follicular variant of papillary thyroid carcinoma using principle component analysis coupled with linear discriminant analysis and a Naïve Bayesian classifier operating on a set of computed spectral metrics. Classification of patients' disease type was accomplished by using average spectra from a wide region containing follicular cells, colloid, and fibrosis; however, classification of disease state at the pixel level was only possible when the extracted spectra were limited to follicular epithelial cells in the samples, excluding the relatively uninformative areas of fibrosis.

    Papillary thyroid carcinoma (PTC) is the most common thyroid cancer with multiple risk factors including exposure to ionising radiation. Oestrogens contribute to papillary carcinoma development by promoting cell proliferation and invasion of mutated epithelial follicular cells. The present study aimed to assess ER-α and PR expression in PTC and to correlate their expression with the clinicopathological parameters in this cancer. Read More

    Purpose: To evaluate the effect of adjuvant external beam radiation therapy (EBRT) on local failure-free survival rate (LFFS) for papillary thyroid cancer (PTC) invading the trachea.

    Materials And Methods: Fifty-six patients with locally advanced PTC invading the trachea were treated with surgical resection. After surgery, 21 patients received adjuvant EBRT and radioactive iodine therapy (EBRT group) and 35 patients were treated with radioactive iodine therapy (control group). Read More

    Differentiated thyroid carcinoma of follicular cell-derivation is the most common endocrine neoplasm with a rapidly increasing incidence. The majority represent papillary carcinomas; more rarely, they are follicular carcinomas. The vast majority have indolent behavior, however a significant proportion progress to develop lymph node metastases and a smaller proportion disseminate systemically. Read More

    Despite the relatively high prevalence of thyroid cancer, the occurrence of multiple synchronous, distinct subtypes of primary thyroid carcinoma is uncommon. The incidental finding of papillary thyroid microcarcinoma in a gland with a biologically relevant follicular or medullary carcinoma is more frequent than the synchronous occurrence of multiple clinically significant carcinomas. We report a case of synchronous papillary and follicular thyroid carcinomas metastatic to lymph node and bone, respectively. Read More

    Surgery for Cardiac Papillary Fibroelastoma: A 12-Year Single Institution Experience.

    BACKGROUND We reviewed our clinical experience with cardiac papillary fibroelastoma from 2005 to 2017. The objective of this study was to investigate the clinical and operative data, as well as the early survival rate and immediate postoperative complications. MATERIAL AND METHODS We performed a retrospective analysis of 11 patients (eight males and three females) who underwent resection of cardiac papillary fibroelastoma in our institution. Read More

    Brugada syndrome in a patient with amyotrophic lateral sclerosis: a case report.

    Background: Amyotrophic lateral sclerosis is a fatal neuromuscular disorder characterized by progressive death of the upper and lower motor neurons in the central nervous system. Patients with this disease die mostly as a result of respiratory failure; however, owing to prolonged survival through assisted ventilation, cardiovascular causes are increasingly responsible for mortality. We report what is to the best of our knowledge the first case of type 2 Brugada syndrome causing ventricular tachyarrhythmia and cardiac arrest in a patient with upper limb onset amyotrophic lateral sclerosis.

    Objective: Distant metastatic spread is the most frequent cause of thyroid cancer-related death. The objective of this study was to evaluate overall and disease-related survival of patients with differentiated thyroid cancer (DTC) and distant metastases (DM) attending a single medical center and to investigate variables predictive of better long-term outcomes.

    Methods: The Rabin Medical Center Thyroid Cancer Registry was searched for patients with DM from DTC. Read More
