Sphenopalatine artery pseudoaneurysm masquerading as a second primary maxillary carcinoma.

Purpose: Maxillary sinus carcinomas usually present as a locally advanced disease at the time of diagnosis and it is extremely unusual to have a second primary maxillary carcinoma on the contralateral side after many years of completion of treatment of the first malignancy. We present here a case report of a sphenopalatine artery (SPA) pseudoaneurysm mimicking the second primary maxillary carcinoma.

Methods: We reviewed the literature for SPA pseudoaneurysm.

Does the extent of neck surgery based on preoperative calcitonin level influence survival in medullary thyroid carcinoma: a retrospective tertiary centre experience.

Introduction: Medullary thyroid carcinoma (MTC) is a rare thyroid cancer arising from the calcitonin-secreting parafollicular cells. Previous studies suggested a preoperative calcitonin level >200ng/l is an indication for prophylactic lateral neck dissection (LND) to remove micrometastases and improve survival outcomes.

Methods: This retrospective single-centre study assessed the efficacy of preoperative calcitonin levels as a marker for determining need for prophylactic LND in MTC.

Routine first-trimester pre-eclampsia screening and risk of preterm birth.

Objectives: Preterm birth (PTB) is a major public health problem worldwide. It can occur spontaneously or be medically indicated for obstetric complications, such as pre-eclampsia (PE) or fetal growth restriction. The main objective of this study was to investigate whether there is a shared uteroplacental etiology in the first trimester of pregnancy across PTB subtypes.
