Photoperiod-induced central actions of thyroid hormone are essential for medullary bone formation

Butterfield Natalie , Miszkiewicz Justyna , Logan John , Leitch Victoria , Yoshimura Takashi , Bassett Duncan , Williams Graham

Seasonal reproduction enables animals outside tropical regions to rear offspring in a favourable environment. Increasing day length triggers a hypothalamic relay involving thyrotropin, the type 2 deiodinase enzyme and thyroid hormone, which activates the hypothalamic-pituitary-gonadal axis to induce reproductive competence. Photoperiod regulates calcium metabolism and the egg-laying cycle in the Japanese quail (Coturnix japonica), and we hypothesised that activity of ...

Pathological basal ganglia calcification in isolated idiopathic hypoparathyroidism: a case report

Pemovska Gordana , Plaseski Tose , Todorova Biljana , Bozhinovska Nadica , Zivkovic Marija , Nesovska Radmila

Introduction: The isolated hyperparathyroidism (IHP) is a metabolism disorder characterized by an absent or low parathormon (PTH) and hypocalcemia. It can be acquired, autoimmune, a result of some syndrome and as a part of a family (FIHP). FIHP is an extremely rear disease which is inherited auto somatic dominant or auto somatic recessive as a result of a mutation of one or several different genes. Pathological calcifications in the cerebrum are a secondary form of calcificati...

Ultrasonographic features of thyroid nodules with suspicious or malignant cytology

Chambidis Vasileios , Siolos Athanasios , Lazarou Lazaros , Efstathiadou Zoe , Panagiotou Athanasios , Adamidou Fotini , Kita Marina

Introduction: Thyroid sonography has become the first line diagnostic procedure for thyroid nodules. The characterization of specific sonografic patterns associated with high risk of malignancy has enabled physicians to determine which nodules are more likely to be malignant and thus merit further evaluation.Aim: We investigated whether the ultrasonographic nodule characteristics proposed in the literature were able to predict cytology findings after ult...

Diagnostic dilemma of a lady with hirsutism and male pattern baldness

Nadeem Sajjad

Forty-three years old lady with background of hypertension was seen in the GP surgery with hirsutism noticed over years. She was referred to the gynaecologist for further work up who in turn discharged her back suggesting possibility of PCOS in view of her biochemical and clinical findings but with no radiological evidence of ovarian cysts.Her PMHx was significant for mild asthma though rarely requiring inhaled steroids.Previously ...

Shear-wave elastography in diagnostics of primary hyperparathyroidism – new application of the method

Stangierski Adam , Wolinski Kosma , Szczepanek-Parulska Ewelina , Ruchala Marek

Introduction: Shear wave elastography (SWE) is a reliable, objective and reproducible technique in sonographic assessment of tissue stiffness. It is considered to be an improvement of conventional ultrasonographic examination. It was demonstrated to be useful in the diagnosis of many thyroid disorders, such as thyroid cancer, Hashimoto’s thyroiditis or Graves’ disease. The aim of our study was to check if SWE can be supportive in the diagnosis of primary hyperparathy...

Oxytocin modulates olfaction-related behaviour and essential for onset of sexual behaviour in both sexes of mice

Dhungel Sunil , Rai Dilip , Nishimori Katsuhiko , Kondo Yasuhiko , Sakuma Yasuo

In microsmatic animals, the olfactory cues initiate wide variety of neuroendocrine and behavioural responses. These behaviours are under the influence of sex hormones however some neuropeptide plays pivotal role. Oxytocin is involved in various social behaviours in mammalian species. However, oxytocin-deficient (OTKO) mice successfully accomplish reproduction although females cannot rear their pups because of lack of lactation. Though oxytocin is not essential for sexual behav...

HRT case presentation: gonadal dysgenesis

Webb Alison

A 28-year-old lady who was born with ambiguous genitalia. A decision was made to rear the patient as male, and was subsequently registered as a boy. Investigations demonstrated a chromosomal mosaic pattern 45XO/46XY fitting the category of mixed gonadal dysgenesis. Internal organs were more suggestive of a female type: uterus, vagina, and fallopian tubes, gonads were variable but typically an ovary on one side and a testis on the other. HCG test showed a brisk rise in serum te...

A case report: non-germinal center type diffuse large B-cell lymphoma in thyroid

Kriksciuniene Ruta , Siusaite Gabija , Klimaite Raimonda

Introduction: The diffuse large B-cell lymphoma (DLBCL) is known as one of the most common lymphoma worldwide with the prevalence of 25 % of all of non-Hodgkin lymphoma cases [1], but it is very rearly observed in thyroid. Around 30 % of Clinical cases of the DLBCL appear from extranodal organs, the prognosis depends on the site of origin [2].Case: A 18-year-old man was admitted to endocrinologist, complaining with a palpable nodule in the front neck for...

Sonoelastographic characteristics of parathyroid tumors

Aleksandrov Yuriy , Belyakov Ivan

In 2016–2020, 181 patients (mean age – 54.8; range 31–77 years) with tumors of parathyroid glands (PG) were operated. All patients had hyperparathyroidism. The diagnosis was confirmed by high levels of ionized calcium and parathyroid hormone (PTH) in the blood. Ultrasound was performed in all patients before surgery. The evaluation of ultrasound images of PG tumors was carried out according to the following parameters: echogenicity, echostructure, shape, clarity...
