This report presents a case of 49-year-old woman with complaint sore throat and front neck pain, who referred to hospital for thyroid scan due suppressed TSH level (0.005 mU/L). Diffuse bilateral lungs uptake in the was noticed incidentally. The patient had positive history COVID-19 symptoms. Multifocal ground-glass opacities (GGOs) both were compatible typical features lung involvement COVID-1...

a long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. this paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by laufer and hulstijn in 2001. it investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning....

Erdheim-Chester disease is a rare non-Langerhans’ cell histiocytosis with characteristic radiological and histological features. This entity is defined by a mononuclear infiltrate consisting of lipid laden, foamy histiocytes that stain positively for CD68. About half of those affected have extraskeletal manifestations, including involvement of the hypothalamus–pituitary axis, lung, heart, retro...

BACKGROUND Thyroid disorders may affect all of the organ systems of the body and they are also highly associated with a wide variety of skin disorders. The aim of this study was to investigate the prevalence of thyroid function abnormalities and thyroid autoimmunity in patients with pemphigus vulgaris (PV) and to determine the association between thyroid disorders and clinical involvement and s...

Goiter is a very common clinical problem; however, Langerhans cell histiocytosis (LCH) with thyroid involvement that presents as a goiter is very rare. In this article, we report one case of thyroid LCH. An 18-year-old male patient presented with goiter, polyuria, polydipsia, and lymphadenectasis of the neck, and LCH was confirmed by a lymph node biopsy and pathological investigation. Withou...

PURPOSE To investigate clinical characteristics and surgical treatment of multifocal papillary thyroid carcinoma. METHODS A total of 648 patients diagnosed with papillary thyroid carcinoma were enrolled, 168 with multifocal papillary thyroid carcinoma. Clinicopathological factors including gender, age at diagnosis, family history of thyroid tumor, multiplicity and bilaterality of tumor, extra...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...

AUF1/heterogeneous nuclear ribonucleoprotein D is an adenylate-uridylate-rich elements (AREs) -binding protein, which regulates the mRNA stability of many genes related to growth regulation, such as proto-oncogenes, growth factors, cytokines, and cell cycle-regulatory genes. Several studies demonstrated AUF1 involvement in the processes of apoptosis, tumorigenesis, and development by its intera...

PURPOSE Decision to perform concurrent ipsilateral thyroidectomy on patients with hypopharyngeal cancer is important, and unnecessary thyroidectomy should be avoided if oncologically feasible. We hypothesized that concurrent ipsilateral thyroidectomy is not routinely required to prevent occult metastasis. This study aimed to determine the prevalence of histological thyroid invasion in patients ...
