Exploring F-FDG uptake patterns in liver, spleen, and bone marrow: Implications for inflammatory and infectious conditions.

Objective: This study aimed to explore the relationship between fluorine-18-fluorodeoxyglucose (F-FDG) uptake in the liver, spleen, and bone marrow and inflammatory markers such as c-reactive protein (CRP), albumin, and erythrocyte sedimentation rate (ESR) in patients undergoing positron emission tomography/computed tomography (PET/CT) imaging for cancer diagnosis.

Subjects And Methods: This retrospective cross-sectional study included a total of 708 patients with a diagnosis of malignancy. Fluorine-18-FDG PET/CT images acquired between January 2021 and December 2022.

Local imaging to interpret tumor size in F18 fluorodeoxyglucose positron emission tomography/CT in lung cancers.

Objective: This study aimed to determine the thoracic and extra-thoracic extension of the disease in patients diagnosed with lung cancer and who had whole-body F18-fluorodeoxyglucose positron emission tomography/CT imaging and to investigate whether there is a relationship between tumor size and extrathoracic spread.

Methods: A total of 308 patients diagnosed with lung cancer were included in this study. These 308 patients were first classified as group 1 (SPN 30 mm>longest lesion diameter ≥10 mm) and group 2 (lung mass (longest lesion diameter ≥30 mm), and then the same patients were classified as group 3 (nodular diameter of ≤20 mm) and group 4 (nodular size of >20 mm).

Low Bone Density and High Sclerostin in Non-Functioning Pituitary Adenoma.

Purpose: Sclerostin reduces bone formation by inhibiting the Wnt signaling pathway in bone tissue. This study evaluated the serum sclerostin level in non-functioning pituitary adenoma (NFPA) patients and analyzed its relationship with bone metabolism.

Method: The data of the patients who applied to the Dicle University Endocrinology, diagnosed with non-functioning pituitary adenoma, and the control group consisting of healthy individuals were included in the study.

Multiple endocrine neoplasia type 2A syndrome (MEN2A) and usefulness of 68Ga-DOTATATE PET/CT in this syndrome.

Aim: The aim of this study was to evaluate a new imaging method 68Ga-DOTATATE PET/CT as an alternative method to diagnose evidence of neuroendocrine tumors or their metastasis (if any) in patient with MEN 2A.

Methods: Three patients( 2F, 1M; age 28,46 and 50 years) with MEN 2A syndrome who underwent 68Ga-DOTATATE PET/CT scan were prospectively evaluated. PET/CT images were analyzed with measurement of maximum standardized uptake value (SUVmax).

Ga-DOTATATE PET/CT Can Be an Alternative Imaging Method in Insulinoma Patients.

Insulinomas are the most common cause of hypoglycemia, resulting from endogenous hyperinsulinism. The diagnosis of insulinoma is established by demonstrating inappropriately high serum insulin concentrations during a spontaneous or induced episode of hypoglycemia. Most insulinomas are islet-cell tumors.

Four decades without diagnosis: Sheehan's syndrome, a retrospective analysis.

Aim: Sheehan's syndrome (SS) remains a frequent cause of hypopituitarism in undeveloped and developing countries, but due to improvements in obstetric care, it is rare in developed countries. We aimed to share the results of a retrospective study analyzing the demographic, clinical, imaging, and hormonal characteristics of a large group of patients with SS, and also increase awareness of this syndrome especially in developed countries.

Methods: The medical records of 124 patients with SS patients who were followed up in the Endocrinology Department of Dicle University between 1995 and 2015 were assessed retrospectively.

Evaluation of insulin sensitivity in hyperprolactinemic subjects by euglycemic hyperinsulinemic clamp technique.

The background and aim of the study is to evaluate insulin sensitivity in hyperprolactinemic subjects via euglycemic hyperinsulinemic clamp technique. Sixteen hyperprolactinemic subjects and 12 healthy subjects were included in the study. HOMA-B and HOMA-IR values of groups were calculated.
