Exploring the Role of Intraoperative Frozen Section of the Sentinel Lymph Node in the Management of Early-Staged Oral Tongue Cancers.

Background: The present study aims to explore the role of sentinel lymph node biopsy (SLNB) with intraoperative frozen section in the management of early-staged oral tongue cancers.

Materials And Methods: Fifty-two patients with clinical stages cT1/2N0 oral tongue cancers were included in the present study. The curative surgery was preceded by the performance of an SLNB using a dual technique.

The diagnostic and therapeutic challenges in the management of a double giant parathyroid adenoma.

Primary hyperparathyroidism is a common endocrine disorder of the parathyroid gland. It is mostly seen as a single gland adenoma in up to 85% of the cases with the excess production of parathyroid hormone. Double adenomas although reported are very rare and double giant parathyroid adenomas are even rarer.

Role of dynamic sentinel node biopsy in carcinoma penis with or without palpable nodes.

Introduction: We aimed to evaluate the role of dynamic sentinel node biopsy (DSLNB) in patients diagnosed with carcinoma penis and clinically N0 disease using superficial inguinal dissection as the standard staging modality.

Materials And Methods: Twenty consecutive men (40 groins) with carcinoma penis having clinically N0 status were enrolled in the study. Patients underwent DSLNB if fine needle aspiration cytology from the groin nodes was negative, followed by injection of radiocolloid and blue dye.

Exploring the role of technitium-99m dimercaptosuccinyl acid (V) scan in medullary carcinoma thyroid patients with postoperative persistent hypercalcitoninemia in the era of positron emission tomography-computerized tomography.

Background: Many radio-pharmaceuticals have been used over the years to localize the recurrences in patients with medullary carcinoma thyroid (MCT), including iodine-131-metaiodobenzylguanidine, thallium-201, technitium-99m dimercaptosuccinyl acid [Tc-99m DMSA (V)], Tc-99m methoxyisobutylisonitril, Tc-99 ethylenediamine diacetic acid/hydrazinonicotinyl-Tyr (3)-octreotide, and In-111 diethylenetriaminepenta-acetic acid-octreotide with varying sensitivities and specificities.

Aims: The aim of this study is to explore the role of Tc-99m DMSA (V) scan in MCT patients with postoperative persistent hypercalcitoninemia in the positron emission tomography-computerized tomography (PET-CT) era.

Materials And Methods: A retrospective review of 53 patients with proven sporadic MCT, who presented to our institution over a period 28 years from 1985 to 2012, was performed.

N-(2-Amino-3,5-dibromo-benz-yl)-N-methyl-cyclo-hexan-1-aminium p-toluenesulfonate.

The title compound, C(14)H(21)Br(2)N(2) (+)·C(7)H(7)O(3)S(-), features a salt of protonated bromhexine, a pharmaceutical used in the treatment of respiratory disorders, and the p-toluenesulfonate anion. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯Br and C-H⋯O hydrogen bonds.
