Differentiated thyroid cancer is one of the most common endocrine cancers. Typical standard treatment includes total thyroidectomy with partial lymphadenectomy, then depending on the indications, treatment with iodine isotope 131-I. A prerequisite to conduct the therapy is to obtain endogenic thyroid-stimulating hormone (TSH) stimulation (TSH > 30 µU/ml). We describe two patients with differentiated thyroid carcinoma in whom no rise in serum TSH was observed after withdrawal of thyroxine. In one patient TSH deficiency was due to partial hypopituitarism secondary to a tumor of the pituitary gland. In the second patient the TSH level was suppressed by metabolically active thyroid tissue within bilateral ovarian teratomas. The problems with TSH growth after withdrawal of thyroxine requires additional studies to identify the cause. Above two possible reasons for the lack of TSH stimulation after withdrawal of thyroxine were presented. In the case of non-TSH stimulation due to hypopituitarism both control tests and isotope treatment should be carried out using stimulation by recombinant human TSH (rhTSH).

Clinical and Laboratory Parameters of Metabolic Syndrome in Chronic Spontaneous Urticaria: A Cross-Sectional Study.
Indian Dermatol Online J

Department of Dermatology, Venereology, and Leprosy, GSL Medical College and General Hospital, Rajahmahendravaram, Andhra Pradesh, India.
Background: Chronic spontaneous urticaria (CSU) appears to share some pathomechanisms with metabolic syndrome (MS), such as proinflammatory state, increased oxidative stress, changes in adipokine profile, and coagulation system activation.
Aim And Objectives: To evaluate clinical and laboratory parameters of MS in CSU patients and to assess relationship of MS with duration and severity of CSU, Ig-E, thyroid-stimulating hormone (TSH), C-reactive protein (CRP), and autologous serum skin test (ASST).
Materials And Methods: A hospital-based cross-sectional study was conducted on 131 CSU cases and 131 controls who were age- and sex-matched.

Graves' disease is caused by overactivation of the thyroid-stimulating hormone receptor (TSHR). One approach for its treatment may be the use of negative allosteric modulators (NAM) of TSHR, which normalize TSHR activity and do not cause thyroid hormone (TH) deficiency. The aim of the work was to study the effect of a new compound 5-amino-4-(4-bromophenyl)-2-(methylthio)thieno[2,3-d]pyrimidine-6-carboxylic acid N-tert-butylamide (TPY4) on the basal and TSH-stimulated TH production in cultured FRTL-5 thyrocytes and on basal and thyrotropin-releasing hormone (TRH)-stimulated TH levels in the blood of rats.

Objectives: Moebius syndrome (MS) is a rare congenital non-progressive rhombencephalic disorder mostly characterised by abducens and facial nerve palsy, but with a multifaceted clinical presentation. Isolated or multiple pituitary hormone deficiencies in the setting of MS have been occasionally reported, but the simultaneous involvement of three or more hypothalamic-pituitary axes has never been described. We hereby report the case of a girl with MS that showed a co-occurrence of GH-, TSH- and ACTH-deficiency.
