In this case, a 44-year-old woman presented with a 15-year history of a swelling in the medial canthus of the right eye that caused tearing.

Sirolimus treatment of a PTEN hamartoma tumor syndrome presenting with melena.

Background: PTEN hamartoma tumor syndrome (PHTS) is an umbrella term including Cowden syndrome (CS), Bannayan-Riley-Ruvalcaba syndrome (BRRS), PTEN-related Proteus syndrome (PS), and PTEN-related Proteus-like syndrome. One of the disorders in PHTS spectrum, CS is characterized by macrocephaly, mucocutaneous findings, gastrointestinal system (GIS) polyposis and an increased lifetime risk of GIS, breast, thyroid and other cancers.

Case: In this study, we report an adolescent patient presenting with recurrent life-threatening upper GIS bleeding as a result of hamartomatous polyposis.

Mitotic Activity in Gastrointestinal Stromal Tumors: Can we use Phosphohistone H3 Immunohistochemistry Instead of Hematoxylin and Eosin for Mitotic Count?

Objectives: In gastrointestinal stromal tumors (GIST), malignancy potential is determined by the prognostic disease risk stratification based on mitosis, tumor size, and location. Phosphohistone H3 (PHH3) is an immunohistochemical marker showing mitotic activity in cells. In this study, we aimed to evaluate mitosis in GIST with PHH3, compare the results with hematoxylin and eosin (HE) stained slides, and examine its relationship with other prognostic data.

Methods: We included cases of ectopic adrenal tissues incidentally detected in the specimens from patients undergoing operation for various diagnoses during 2012- March 2020.

Succinate Dehydrogenase Complex Iron Sulfur Subunit B (SDHB) Immunohistochemistry in Pheochromocytoma, Head and Neck Paraganglioma, Thoraco-Abdomino-Pelvic Paragangliomas: Is It a Good Idea to Use in Routine Work?

Background: In this study, we aimed to detect Succinate Dehydrogenase Complex Iron Sulfur Subunit B (SDHB) frequency in paragangliomas and pheochromocytomas (PPGL) with immunohistochemistry; compare with Pheochromacytoma of the Adrenal Gland Scaled Score (PASS) classification and analyse the differences between pheochromocytoma (Pheo), head-neck paragangliomas (HNPGL) and thoraco-abdominal-pelvic paraganglioma (TAPPGL) sub-groups.

Methods: A total 114 PPGL cases (73 HNPGL, 15 TAPPGL and 27 Pheo belonging to 112 cases) are included. Immunohistochemically, SDHB and Ki-67 are investigated and malignancy risks are determined by PASS classification.

Culturally modified olfactory test adapted to East-Turkey: A comparison with Sniffin' Sticks.

Background: Although the "Sniffin' Sticks" test (SST) is a widely used odor test, aplicability of odor tests is limited because of the high cost of the test and the regional-cultural differentiation of odor recognition. We aimed to evaluate our regional odor norms by applying the SST with a Modified odor test (MOT) we created for this study, and to develop a test similar to the SST, which was less expensive and probably had a higher odor definition for our region.

Methods: This study includes 201 healthy volunteers: 91 men and 110 women over the age of 18 were included in the study.

Extramedullary myeloma in ectopic parathyroid adenoma: A case report.

Extramedullary myeloma, a subgroup of multiple myeloma, is a rare condition characterised by extra-skeletal infiltration of clonal plasma cells. Although parathyroid adenoma's co-morbidity with multiple myeloma is common, extramedullary myeloma, an ectopic parathyroid adenoma has not been reported in the literature. This is the first study in literature that presents extramedullary myeloma that infiltrated ectopic parathyroid adenoma in the mediastinum after multiple myeloma treatment.

BRAF V600E mutation in papillary thyroid cancer is correlated with adverse clinicopathological features but not with iodine exposure.

The literature suggests that mitochondrial DNA (mtDNA) defects are associated with a large number of diseases including cancers. The role of mtDNA variations in thyroid cancer is a highly controversial topic. Therefore, we investigated the role of mt-DNA control region (CR) variations in thyroid tumor progression and the influence of mtDNA haplogroups on susceptibility to thyroid tumors.

THE RESULTS OF PARATHYROID HORMONE ASSAY IN PARATHYROID ASPIRATES IN PRE-OPERATIVE LOCALIZATION OF PARATHYROID ADENOMAS FOR FOCUSED PARATHYROIDECTOMY IN PATIENTS WITH NEGATIVE OR SUSPICIOUS TECHNETIUM-99M-SESTAMIBI SCANS.

Objective: This study aimed to evaluate the results of parathyroid hormone (PTH) assay in parathyroid aspirates to determine uniglandular disease by an endocrinologist-performed ultrasound (US) in patients with discordant or negative technetium-sestamibi scans and to evaluate whether this procedure increases the number of focused parathyroidectomies (FPs).

Methods: We analyzed the data of 65 patients who underwent an endocrinologist-performed US-guided parathyroid fine-needle aspiration (FNA) with PTH wash-out, retrospectively. The results of PTH wash-out procedure and the reports of parathyroid surgery and pathology were reviewed.

The protective effect of intratympanic dexamethasone on streptomycin ototoxicity in rats.

The purpose of this experimental study was to investigate the protective role of intratympanically administered dexamethasone on the inner ears of rats that were exposed to streptomycin ototoxicity. Twenty-four adult Wistar albino rats were separated into 4 groups: Group 1 (only streptomycin), Group 2 (only intratympanic dexamethasone), Group 3 (streptomycin and intratympanic dexamethasone), and Group 4 (streptomycin and intratympanic saline). All rats were evaluated with distortion product otoacoustic emissions (DPOAE) tests before the start of treatment and on the day it ended.

Relationship of mast cell density with lymphangiogenesis and prognostic parameters in breast carcinoma.

Correlation of BRAF mutation and SUV levels in thyroid cancer patients incidentally detected in F-fluorodeoxyglucose positron emission tomography.

The prognostic importance of F-fluorodeoxyglucose avidity in primary thyroid tumor and molecular basis responsible for its mechanism has not yet been well characterized. In this study, we aimed to evaluate the correlation between the maximum standardized uptake levels and B-type Raf kinase mutation positivity in incidentally detected papillary thyroid cancer patients during F-fluorodeoxyglucose positron emission tomography examination. We retrospectively evaluated 6873 F-fluorodeoxyglucose-positron emission tomography scans of consecutive subjects from a database search for tumor staging in 2014 at our hospital Nuclear Medicine Center.

Efficacy of N-Acetylcysteine on Wound Healing of Nasal Mucosa.

Postoperative nasal mucosa healing is a highly complex and organized process, and the success rates of endoscopic sinus surgery and septoplasty surgeries are closely associated with the postoperative wound healing processes. In this experimental study, the authors' aim was to use histopathologic examination to investigate the effects of N-Acetylcysteine (NAC) on the wound healing of rat nasal mucosa after mechanical trauma. Twenty-one Sprague-Dawley rats were randomly divided into 3 groups: the nontreated group (N = 7), the control saline group (N = 7), and the NAC group (N = 7).

Radiologic and surgical findings in chronic suppurative otitis media.

Our aim in this study was to evaluate the efficiency of preoperative temporal bone computed tomography (CT) in detecting pathologic conditions in patients with chronic suppurative otitis media (CSOM).
