Abstract Aim Thyroid resection is commonly used to manage thyroid problems. Incidental parathyroidectomy a recognised complication associated with thyroidectomy. Findings of parathyroid gland in the pathology specimen varies greatly as reported literature between 6.4%-31%. The aim this project was determine local incidence incidental during and comparing it rates literature. Method Retrospectiv...
BACKGROUND Inadvertent removal of the parathyroid glands during elective thyroid surgery occurs more frequently in certain high-risk patients and can lead to symptomatic hypocalcaemia. METHODS A case-control study was carried out at a tertiary referral, academic medical centre between May 1994 and August 2001. Five hundred and thirteen patients underwent thyroid resection. Pathology reports w...
Carcinoma of the parathyroid gland is rare, constituting about 1% of most series of patients with hyperparathyroidism. In 1969 a collective review identified forty-six unequivocal cases, and since then a further seven cases have been described in the literature. A brief review of the condition is presented, and one further case of hyperfunctioning adenocarcinoma of the parathyroid gland is repo...
Parathyroid glands were removed from routine necropsy cases, being mainly elderly subjects of both sexes. Gelatine-embedded blocks of formalin-fixed and post-chromed tissue were prepared and stained by Baker's (1946) acid-haematin technique for the histochemical detection of phopholipids. Near-by sections (although not strictly serial) were stained by haematoxylin and eosin. In each case a seco...
abstract men-i is a rare genetic disorder classically characterized by a predisposition to tumors of the parathyroid glands, anterior pituitary gland, and pancreatic islet cells. we present a case of men-i syndrome diagnosed using predominantly nuclear medicine imaging followed by radionuclide therapy, thus emphasizing the role of nuclear imaging in diagnosing and treating men-i.
background although neuregulin-1 (nrg1)and its receptors have been indicated at the mrna level in partial human endocrine organs and its functional roles have been evaluated in vitro, their morphological distribution in higher animals are not fully studied. the present research focused on expression of nrg1 and its main receptors erbb2 and erbb4 in main endocrine organs of the rhesus monkey. ma...
Primary Hyperparathyroidism is a condition in which parathyroid gland secrets high levels of Parathyroid hormone and loses the ability to regulate Parathyroid hormone secretion via a negative feedback mechanism with serum calcium level (Geffken 1998). This hormone increases serum calcium by increasing bone resorption, intestinal absorption and decreasing renal excretion resulting in vicious cyc...
UNLABELLED BACKGROUND Thyroid hemiagenesis is a rare anomaly, more commonly seen on the left side (ratio 4:1) and in females (ratio 3:1). The first to describe this anomaly was Handfield Jones in 1852. CASE PRESENTATION We present a 66 year old female patient with right thyroid hemiagenesis, parathyroid adenoma on the side of hemiagenesis and parathyroid hyperplasia on the contralateral si...
Parathyromatosis, in which several nodules of hyperfunctioning parathyroid tissue form in the neck and mediastinum, is a rare cause of recurrent hyperparathyroidism. However, there are some theories regarding the origin of parathyromatosis, and seeding after rupture of the parathyroid gland capsule during surgical removal of a parathyroid lesions is the most regarded one. Herein, we report a 41...
