Unlabelled: Medullary thyroid carcinoma (MTC) is a rare and challenging type of thyroid cancer originating from parafollicular cells (C cells) that produce calcitonin. Diagnosing and monitoring this carcinoma can be complex due to its unique biomarkers. Procalcitonin (PCT), a precursor of calcitonin, and carcinoembryonic antigen (CEA) are important markers for MTC.

A Rare Post-Infectious Autoimmune Manifestation of COVID-19.

Eur J Case Rep Intern Med

May 2024

Department of Internal Medicine, Faculty of Medicine, Maltepe University Hospital, Istanbul, Turkey.

Article Synopsis
  • The rise in post-infectious autoimmune diseases, such as relapsing polychondritis (RP), has been observed following COVID-19, particularly in patients with pre-existing conditions like autism.
  • An autistic patient developed RP months after a mild COVID-19 infection, suggesting that the infection may trigger autoimmune responses through immune system dysregulation.
  • The hyperactive immune responses in autism, along with factors such as lymphocytopenia and elevated neutrophils during COVID-19, may contribute to a higher risk of developing autoimmune diseases post-infection.

Background: Radial angiography, preferred for its safety and comfort in percutaneous coronary interventions, occasionally leads to paresthesia-a tingling or numbing sensation in the hand. This study aimed to investigate the presence of nerve damage in patients experiencing paresthesia post-radial angiography through electrophysiological examination.

Methods: This prospective study involved 77 patients who developed hand paresthesia following radial angiography.

July 2024

Acibadem University, School of Medicine, 34752, Istanbul, Turkey; Acibadem Altunizade Hospital, Tophanelioglu cad 13, Altunizade, 34662, Istanbul, Turkey. Electronic address:

Aim: We aimed to investigate the efficiency and accuracy of an artificial intelligence (AI) algorithm for detecting interval cancers in a middle-income country's national screening program.

Material And Methods: A total of 2,129,486 mammograms reported as BIRADS 1 and 2 were matched with the national cancer registry for interval cancers (IC). The IC group consisted of 442 cases, of which 36 were excluded due to having mammograms incompatible with the AI system.

Objectives: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) has been recognised in recent years, and there is extensive ongoing research. Although the exact mechanism and cause are still unclear, we now know that the disease is more associated with textured implants. To the best of our knowledge, no previous studies investigating the radiological differential of various implants have been conducted.

In recent years, microfluidic chip-based sperm sorting has emerged as an alternative tool to centrifugation-based conventional techniques for in vitro fertilization. This prospective study aims to compare the effects of density gradient centrifugation and microfluidic chip sperm preparation methods on embryo development in patient populations with astheno-teratozoospermia. In the study, the semen samples of the patients were divided into two groups for preparation with either the microfluidic or density gradient methods.

Aim: YouTube is one of the most popular video-sharing platforms and is used by many people as a source of information regarding health conditions. Although there are many studies examining YouTube health-related videos in terms of quality, content and accuracy, there is not any study observing the content of YouTube videos about the "Pap smear test." Therefore, we intended to evaluate YouTube videos related to the Pap smear test.

This study aimed to determine the change in sexual function among Turkish women through decades and to define the association between sexual dysfunction and androgens and cardiometabolic features. A total of 206 postmenopausal women aged 50-69 years and 210 premenopausal women aged 30-49 years who applied to menopause and gynecology clinics at a university-affiliated education and research hospital were included in this prospective study. Groups were constructed according to decades (i.

Mitochondrial depletion in CD4 and CD19 peripheral lymphocytes in early stage Alzheimer's disease.

Mech Ageing Dev

October 2017

HLA Typing Laboratory, Yeditepe University Hospital, İstanbul, Turkey; Department of Immunology, Faculty of Medicine, Yeditepe University, İstanbul, Turkey.

Article Synopsis
  • * Researchers measured mitochondrial DNA (mtDNA) levels and used flow cytometry to analyze mitochondrial-specific antibodies in different types of lymphocytes (CD4, CD8, CD19, CD56).
  • * Findings show that early stage AD patients have significantly reduced mtDNA and protein levels in CD4 and CD19 lymphocytes, indicating mitochondrial depletion in these cells.

Purpose: The most important prognostic variable for early stage breast cancer is the status of axillary lymph nodes. The aim of this study was to evaluate the diagnostic accuracy of preoperative magnetic resonance imaging (MRI) for metastatic axillary lymph node in breast cancer cases with post-operative sentinel lymph node biopsy (SLNB) results.

Materials And Methods: Women aged between 21 and 73 years who were diagnosed with malignant mass lesion of the breast between 2013 and 2015 were included in this study.

Lung cancer in the pregnant woman is a very rare and dramatic coincidence with poor prognosis. Treatment depends on the gestational week of the pregnancy, patient's medical status, social, personal, familial, and even religious beliefs. We present a case of adenocarcinoma of the lung in a 34-year-old pregnant patient whose initial complaints were cough, dyspnea, fever and fatigue.

Palpable lesion(s) noticed in a patient with thoracic disease may be a useful diagnostic tool and it often gives a clue for further management. In this study, we searched the diagnostic value of palpable lesions in patients with thoracic pathology suspected clinically and/or radiologically. We prospectively examined the correlations of clinical/radiologic and pathologic findings of 72 palpable lesions from 68 patients who presented with suspect for a thoracic disease from two tertiary medical centers.

The objective of this paper is to contrast the use of a longitudinal incision in surgical decompression of De Quervain disease with a transverse incision. The advantages are ease in recognition of compartment variations and superficial branches of radial nerve and prevention of palmar tendon subluxation by permitting a more dorsal release of the compartment sheath. Since 2002, we have used a longitudinal skin incision instead of the classic transverse incision to release the first dorsal compartment.
