Abstract
PURPOSE Acromegaly is associated with oxidative stress and inflammation parameters. Chitotriosidase (CHITO) is a marker of macrophage activation and plays a pivotal role in the activation of inflammatory and immunological responses. Our study aimed to determine CHITO,YKL-40, advanced glycation end product (AGE), and high-sensitivity C-reactive protein (hsCRP) levels to investigate malondialdehyde (MDA), catalase, superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities and to evaluate any association of these parameters with carotid intima media thickness (cIMT) in patients with controlled acromegaly. METHODS Thirty controlled acromegaly patients and 41 age- and sex-matched control cases were studied. We obtained demographic data, hormonal and metabolic parameters, and cIMT. CHITO activity was measured with the fluorometric method of Chamoles et al. YKL-40 and hsCRP levels were measured using ELISA. AGEs were measured based on spectrofluorimetric detection. GSH-Px activity was determined by a colorimetric assay. MDA, SOD, and catalase activities were determined in hemolysis. RESULTS Higher CHITO, AGE, and hsCRP concentrations were observed in patients with acromegaly compared to controls. SOD levels were non-significantly higher in the acromegaly group, while catalase activities were lower in patients with acromegaly. Correlation analyses of CHITO, AGEs, YKL-40, hsCRP, MDA, catalase, GSH-Px, and SOD with metabolic, anthropometric, and laboratory parameters did not demonstrate any significant correlation (p > 0.05). There was no significant difference between groups with regard to cIMT levels. CONCLUSION This is the first study investigating CHITO and AGE levels in patients with acromegaly. Serum CHITO, AGE, and hsCRP levels in acromegalic patients were significantly increased. It may be important to evaluate CHITO, AGE, and hsCRP levels in acromegalic patients who are already under cardiometabolic surveillance due to risk of developing cardiovascular disease.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer and accounts for 85-90% of all thyroid cancers. Metastatic differentiated thyroid cancer, radioiodine-refractory thyroid cancer, and anaplastic thyroid cancer still lack effective therapeutic options. Here, we aimed to assess HDAC9 and P300 expression in the papillary thyroid carcinoma cell line and compare them with normal thyroid cells. METHODS Nthy-ori-3-1, a normal thyroid cell line, and BCPAP, a PTC cell line, were cultured for 24 and 48 h and immunofluorescence staining was used to determine the levels of HDAC9 and P300 protein expression. HDAC9 paracrine release was assessed using an ELISA assay. RESULTS HDAC9 protein expression was higher in both cell groups at the 48th hour than at the 24th hour; however, P300 protein expression was lower in BCPAP cells at the 48th hour than at the 24th hour. In comparison to Nthy-ori-3-1, BCPAP expressed more HDAC9 and P300 proteins. HDAC9 secretion slightly increased in Nthy-ori-3-1 cells from 24 to 48 h. Furthermore, HDAC9 secretion in BCPAP cells dramatically decreased from 24 to 48 h. CONCLUSION Our findings revealed that the expression of HDAC9 and P300 was higher in the PTC cell line than in normal thyroid cells. This indicates that the acetylation mechanism in thyroid cancer cells is not the same as it is in healthy cells. Epigenetic studies may reveal the mechanisms underlying PTC with further analysis.

Abstract
INTRODUCTION Pituicytoma is a rare tumor of the pituitary gland derived from neurohypophyseal pituicytes. CASE 1: A 58-year-old female presented with decreased vision; she was admitted to the neurosurgery department of Ege University after the detection of a pituitary macroadenoma. Magnetic resonance imaging (MRI) showed a 28 * 18 * 17-mm suprasellar mass, and laboratory tests revealed hypopituitarism. Hydrocortisone and L-thyroxine treatment were initiated, and the patient underwent resection through the endoscopic endonasal approach (EEA). The histopathological examination revealed a pituicytoma. The recurrence of tumor was detected during the 1-year follow-up, and the patient is awaiting surgery. CASE 2: A 70-year-old woman presented with visual changes; she had a past medical history of hypophyseal macroadenoma and pituicytoma resected through an EEA in 2012 and 2017, respectively. During follow-up, 2 years after the second surgery, MRI showed progression of the pituicytoma then measuring 38 × 23 × 22 mm; it had invaded the cavernous sinus and was causing hydrocephaly and panhypopituitarism. The patient underwent the third resection through the transcranial approach in order to minimize bleeding. After this surgery, the patient developed diabetes insipidus and underwent treatment with desmopressin. Histopathological examination revealed a pituicytoma. At 6-month follow-up, imaging showed a sellar suprasellar mass 37 × 22 × 24 mm invading the cavernous sinus, indicative of recurrence. In the postoperative period, the patient applied to the department of radiation oncology to have fractionated radiotherapy. DISCUSSION Pituicytomas are known to be low-grade tumors; because of their rarity, they are a real challenge. These patients should be followed up closely.

Abstract
Introduction Fahr's syndrome is an infrequent disorder characterized by bilateral symmetrical calcification of basal ganglia and the cerebral cortex. It can be seen genetic, idiopathic, or secondary to endocrine diseases. This disease is related to different metabolic disorders particularly with diseases of the parathyroid gland. Case 1 A 63-year-old female patient applied to our clinic due to having hypoparathyroidism with bilateral basal ganglia calcification in head computed tomography(CT). She had subtotal thyroidectomy 25 years ago. In the neurological examination, mild symmetrical parkinsonism was determined. In laboratory examination Ca:8 mg/dL (8.6-10.2), P:5.1 mg/dL (2.3-4.5), PTH:9.53 pg/mL (15-65) were detected. Calcitriol 0.25 μ/day was added to her treatment. Her parkinsonism disappeared after the treatment. Case 2 A 49-year-old male patient was consulted when he was admitted to the department of neurology in our hospital. The physical examination demonstrated the characteristics of Albright's hereditary osteodystrophy. The neurological examination shows bilateral symmetrical bradykinesia, dysphagia, and moderate dysarthria. In the laboratory examination PTH: 46.5 ng/L(15-65), Ca:8.6 mg/dL (8.6-10.2), P:2.7 mg/dL (2.3-4.5) were detected and were all within the normal ranges. Consequently, pseudopseudohypoparathyroidism was decided as a diagnosis. G protein alpha subunit mutation (Gsα) was not detected due to technical limitations. Conclusion When a patient is diagnosed as Fahr's syndrome, we should keep in mind parathyroid disorders. Fahr's syndrome must be evaluated in patients showing intracranial calcification accompanied by parathyroid diseases.

Abstract
INTRODUCTION Prolactin plays a significant role in lactation and prolactin levels are increasing physiologically in pregnancy and breastfeeding period. There might be different mechanisms during breastfeeding between prolactin and insülin levels. In order to highlighten this mechanisms we compared the plasma levels of glucose, insülin, prolactin, C-peptid in basal situations and after taking 75 gr carbonhydrate, 20 gr protein, 23 gr fat in breastfeeding and in non lactating women. MATERIAL AND METHODS Participiants and measurements: The study population included 12 breastfeeding women and 11 healthy non lactating women as a control group. We collected information on age, history of gestational diabetes mellitus, family history of diabetes mellitus, natality, the symptoms of hypoglycemia. Weight, height and waist circumference were measured and body mass index (BMI) was calculated as weight (kg)/height (m2). RESULTS Prolactin was inversely correlated with HbA1c and 2. hour C peptide (p=0.005, r=-0.564; p=0.008, r=-0.539). Prolactin was not significantly correlated with HOMA-IR, HOMA-IS, AUC-I or AUC-G. Prolactin levels were higher in breastfeeding women (median:34.98 μg/L) than in non lactating women (median:12.21 μg/L, p<0.001). There was a significant association between age and fasting glucose (p=0.018, r=-0.665), 2. hour glucose (p=0.049, r=0.578) in breastfeeding women. DISCUSSION In our study, we displayed prolactin was inversely correlated with HbA1c and 2. hour C peptide. Some studies in the past demonstrated that higher prolactin levels had importantly lower prevelance of type 2 diabetes. Our findings supported this situation.

Abstract
Congenital adrenal hyperplasia is one of the most common autosomal recessive genetic disorders. Testicular adrenal tumors are significant complications of congenital adrenal hyperplasia. We would like to present two patients of testicular adrenal rest tumors. Patient 1 24 year-old male, he was diagnosed with congenital adrenal hyperplasia at the age of 8 due to precocious puberty. He received hydro-cortisone treatment until the age of 18. Testicular mass had been detected and right radical orchiectomy had been applied 6 months ago and reported as testicular adrenal rest tumor. In scrotal ultrasound, a mixed type mass lesion (6 × 4x3 cm) covering a large part of left testis was observed. The imaging findings were consistent with adrenal rest tumor. The patient took adrenocorticotropic hormone supressive therapy with dexamethasone 0.75 mg once a day. Patient 2, 38 year-old male, he had been followed-up as adrenal insufficiency for 35 years. He underwent right orchiectomy operation due to the testicular mass in 2010 and the pathological examination revealed Leydig cell tumor. In scrotal ultrasound, small multifocal lesions were detected on the left testis and resection was done. It was reported as testicular adrenal rest tumor. He is being followed-up with glucocorticoid treatment according to androgen and adrenocorticotropic hormone levels. Early diagnosis of testicular adrenal rest tumor is significant in preventing irreversible testicular damage and infertility. In the differential diagnosis, we should keep in mind that testicular adrenal rest tumor can mimic other testicular tumors such as primary germ cell tumors.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) has none of the targeted treatment choices due to its distinct biological property, making this subtype a unique disease. In this study, we evaluated the impact of obesity on clinical outcomes of TNBC. METHODS The data of breast cancer patients admitted to our department were collected. TNBC was defined as lack of estrogen receptor (ER), progesterone receptor (PR) and HER-2. The body mass index (BMI) of 112 TNBC patients was calculated with weight at the time of diagnosis and height. The patients were classified into groups with a BMI of < 25 (normal/underweight), 25-29.9 (overweight) or ≥ 30 (obese). After a mean follow-up of 23.2 ± 15.5 months, there were 12 recurrences (10.71%) and 6 deaths (5.35%). Disease-free survival (DFS) and overall survival (OS) were assessed. RESULTS The survival analyses of all the patients did not demonstrate any differences in OS or DFS in obese as compared to non-obese patients. However, we showed that obesity was associated with a poorer OS for postmenopausal TNBC patients (p < 0.05). CONCLUSION Obesity is related to a poorer OS in postmenopausal TNBC patients. Due to the heterogeneous disease profile of TNBC, larger randomized studies will be needed to clarify the exact role of obesity in TNBC.
