Unlabelled: The aim of our study was an estimation of the size and structure of the pituitary gland using MRI and the estimation of hormonal profile of the pituitary anterior lobe (except for ACTH) in 21 adult patients with congenital primary hypothyroidism.
Material And Methods: The studied group was divided into 2 subgroups: A--with normal level of serum TSH and B--with its elevated. The MRI showed pituitary hyperplasia or tumor in 28.5% of patients, partially empty sella in 14.3% and hypoplasia in 9.5%. In subgroup B there were mostly hyperplasia or tumor (35.7%), while in subgroup A there were no domination of any abnormalities.
Results: Serum mean TSH level was 49.8+/-86.2 mU/l with an increase in 67%. The mean prolactin was 11.2+/-7.5 mg/ml with an increase in 19%. Serum LH and FSH concentrations were normal in the whole group. The mean alpha subunit level was elevated in 52%. In 42.8% somatotropic hypopituitarism was recognised due to GH stimulation tests.
Conclusions: The TRH hyperstimulation in patients with congenital primary hypothyroidism may lead to pituitary hyperplasia or tumor visible on MRI and to pituitary hormonal abnormalities.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Objective: Using F-FDG PET/CT metabolic parameters to differentiate post-transplant lymphoproliferative disorder (PTLD) and reactive lymphoid hyperplasia (RLH), and PTLD subtypes.
Methods: F-FDG PET/CT and clinical data from 63 PTLD cases and 19 RLH cases were retrospectively collected. According to the 2017 WHO classification, PTLD was categorized into four subtypes: nondestructive (ND-PTLD), polymorphic (P-PTLD), monomorphic (M-PTLD), and classic Hodgkin.

Background: Despite extensive analysis, the dynamic changes in prostate epithelial cell states during tissue homeostasis as well as tumor initiation and progression have been poorly characterized. However, recent advances in single-cell RNA-sequencing (scRNA-seq) technology have greatly facilitated studies of cell states and plasticity in tissue maintenance and cancer, including in the prostate.
Methods: We have performed meta-analyses of new and previously published scRNA-seq datasets for mouse and human prostate tissues to identify and compare cell populations across datasets in a uniform manner.

Background: Post-transplant lymphoproliferative disease (PTLD) is a significant complication that can arise following solid organ transplantation or hematopoietic stem cell transplantation. It encompasses a spectrum of lymphoproliferative lesions, ranging from benign reactive hyperplasia to malignant tumors, and is among the most severe complications following liver transplantation in children. It is essential for clinicians to gain a comprehensive understanding of the prevention, clinical manifestations, early diagnosis, and treatment strategies for PTLD in order to reduce mortality rates.

Background: The aim of this study was to assess the clinicopathological features of lip lesions diagnosed in a single Oral Pathology service in Brazil.
Material And Methods: It was a cross-sectional study based on secondary data. Between 2000 and 2019, all lip lesions diagnosed in an Oral Pathology service in Brazil were analyzed.
