Tension-type headache (TTH) is the most prevalent primary headache. Chronic TTH (CTTH), the most serious form of TTH, is refractory, with a high socio-economic burden. Research studies have shown patients with migraine often had cognitive impairment, but few studies have focused on the cognition in CTTH patients. In the present study, we assumed that patients with CTTH also have cognitive impairments, which are modulated by the neuroendocrine state. Participants were recruited, including CTTH patients and healthy controls...

Patients with bilateral pheochromocytoma often require an adrenalectomy. Autotransplantation of the adrenal cortex is an alternative therapy that could potentially be performed instead of receiving glucocorticoid replacement following adrenalectomy. Adrenal cortex autotransplantation aims to avoid the side effects of long‑term steroid treatment and adrenal insufficiency. Although the function of the hypothalamo‑hypophysial system is critical for patients who have undergone adrenal cortex autotransplantation, the details of that system, with the exception of adrenocorticotropic hormone in the subjects with adrenal autotransplantation, have been overlooked for a long time...

The absorption dose outside the irradiation field for prostate intensity-modulated radiation therapy was measured and evaluated by comparison with calculated values of radiation treatment planning system (TPS). The values of TPS calculated were using Varian CLINAC21EX/Eclipse and TomoTherapy Planning System for constant irradiation time. The absorption dose was measured by placing a glass-element dosemeter in a human-bone enclosure phantom with a planning target volume inside the irradiation field. The organs at risk were the rectum, spinal cord, thyroid, eyeball and the left lung...

Intensity-modulated radiation therapy (IMRT) can deliver high and homogeneous doses to the target area while limiting doses to organs at risk. We used a pediatric phantom to simulate the treatment of a head and neck tumor in a child. The peripheral doses were examined for three different IMRT techniques [dynamic multileaf collimator (DMLC), segmental multileaf collimator (SMLC) and volumetric modulated arc therapy (VMAT)]. Peripheral doses were evaluated taking thyroid, breast, ovary and testis as the points of interest...

The purpose of this study was to measure out-of-field organ doses in clinical conditions in anthropomorphic paediatric phantoms which received a simulated treatment of a brain tumour with intensity modulated radiotherapy (IMRT) and 3D conformal radiotherapy (3D CRT). Organ doses measured with radiophotoluminescent and thermoluminescent dosemeters were on average 1.6 and 3.0 times higher for the 5 y-old than for the 10 y-old phantom for IMRT and 3D CRT, respectively. A larger 5-y to 10-y organ dose ratio for 3D CRT can be explained because the use of a mechanical wedge for the 5-y-old 3D CRT phantom treatment increased out-of-field doses...

The differential diagnosis of neuroendocrine neoplasms of the larynx is broad and includes lesions of epithelial, mesenchymal, and neuroectodermal origin. These lesions have overlapping clinical and pathologic aspects and must be carefully considered in the differential diagnosis of laryngeal neoplasms. The prognosis and treatment are also different among these tumor types, which necessitates making these distinctions clinically. The current literature was reviewed to provide updated information regarding the epithelial-derived tumors, including carcinoid, atypical carcinoid, small cell neuroendocrine carcinomas, large cell neuroendocrine carcinoma, and squamous cell carcinoma with neuroendocrine component...

BACKGROUND: Ultrasonography for thyroid nodules is one of the most common imaging tests performed in the general population. Details from ultrasound reports guide biopsies and surgery. This study quantifies the completeness of these reports based on Thyroid Imaging and Reporting System (TI-RADS) criteria and considers their utility in predicting malignant disease. METHODS: We retrospectively reviewed ultrasound reports for 329 thyroidectomy patients and extracted data elements using the TI-RADS criteria: nodule size, echogenicity, margins, vascularity, solid/cystic composition and the presence or absence of microcalcifications and the halo sign...

BACKGROUND: Thyroid cancer (TC) is the most common endocrine malignancy. TC patients have a good prognosis and a low disease-related mortality rate. Since the patients are often young, they may be at a higher risk for a second primary malignancy (SPM). We sought to determine the incidence, risk and types of SPM between 1980-2011, and to assess SPM trends over time among Israeli TC patients. METHODS: Data were derived from the Israel National Cancer Registry. Primary TC patients diagnosed during 1980-2009 were followed-up for SPM incidence until December 31, 2011...

OBJECTIVE: There is debate whether hemithyroidectomy is sufficient for patients with papillary thyroid cancer (PTC) sized 1-4 cm. Therefore, we investigated whether hemithyroidectomy affects recurrence rate compared with thyroidectomy in patients with PTC sized 1-4 cm. DESIGN: Retrospective observational study. PATIENTS: We included 147 patients with 1-4 cm PTC who underwent hemithyroidectomy between 2004 and 2008. They were matched with 298 patients who underwent thyroidectomy, comparing age, sex, tumor size, multiplicity, and extrathyroidal extension status, and lymph node (LN) metastasis status...

Neck pain is a common complain, being in most cases due to non-thyroidal causes. However, a minority of patients suffer from painful thyroid diseases. Among them, sub-acute thyroiditis (SAT) is the most frequent one. Rare thyroid-related causes of neck pain include hemorrhage within a thyroid nodule as well as Riedel's thyroiditis and suppurative thyroiditis. In the last 30 years, a few cases of a painful variant of Hashimoto's thyroiditis (HT) have been described. Biochemical, ultrasound, and histologic features were clearly suggestive for HT in all of the published cases and definitely ruled out the diagnosis of SAT...

The relationship of low-dose background gamma radiation and childhood leukaemia was investigated in a number of studies. Results from these studies are inconclusive. Therefore, in the present study 25 years of German childhood cancer data were analyzed using interpolated background annual gamma dose rate per community in an ecological study. The main question was leukaemia; as exploratory questions we investigate central nervous system (CNS) tumours, thyroid carcinomas and diagnoses less likely to be related to radiation...

BACKGROUND: Despite the new technical alternative offered by the robotic surgery for minimally invasive thyroid surgery, the role of the robotic thyroidectomy (RT) in thyroid cancer has been highly disputed. This paper gives a systematic review and meta-analysis aiming to compare RT and open thyroidectomy (OT) based on the surgical outcomes and oncologic results. METHODS: Relevant literature was searched from various databases up to July 2016, including PubMed, MEDLINE, EMBASE, Cochrane Library, Web of science and Clinical Trials...

Poly r(C) binding protein (PCBP) 1 or heterogeneous ribonucleoprotein (hnRNP) E1 is a RNA binding protein that plays a vital role in a wide variety of biological processes. PCBP1 has been shown to function as a tumor suppressor by negatively regulating translation of pro-metastatic proteins in different cancers. Loss of PCBP1 expression or its Akt2-mediated phosphorylation at serine 43 residue has both been indicated to de-repress its regulation of EMT inducer proteins. Our previous work has established that PCBP1 functions as a tumor suppressor in thyroid cancer, where its translation is inhibited by microRNA-490-3p...

Soy-food and its isoflavones, genistein (G) and daidzein (D), were reported to exert mild cholesterol-lowering effect, but the underlying mechanism is still unclear. In this research, first we studied age-related alterations in hepatic cholesterol metabolism of acyclic middle-aged (MA) female rats. Then we tested if purified isoflavones may prevent or reverse these changes, and whether putative changes in hepatic thyroid hormone availability may be associated with this effect. Serum and hepatic total cholesterol (TChol), bile acid and cholesterol precursors, as well as serum TSH and T4 concentrations, hepatic deiodinase (Dio) 1 enzyme activity and MCT8 protein expression were determined by comparing data obtained for MA with young adult (YA) intact (IC) females...

Hypothyroidism is a common condition of thyroid hormone deficiency, which is readily diagnosed and managed but potentially fatal in severe cases if untreated. The definition of hypothyroidism is based on statistical reference ranges of the relevant biochemical parameters and is increasingly a matter of debate. Clinical manifestations of hypothyroidism range from life threatening to no signs or symptoms. The most common symptoms in adults are fatigue, lethargy, cold intolerance, weight gain, constipation, change in voice, and dry skin, but clinical presentation can differ with age and sex, among other factors...

REVIEW

The treatment of thyroid cancer has promising prospects, mostly through the use of surgical or radioactive iodine therapy. However, some thyroid cancers, such as progressive radioactive iodine-refractory differentiated thyroid carcinoma, are not remediable with conventional types of treatment. In these cases, a treatment regimen with multi-kinase inhibitors is advisable. Unfortunately, clinical trials have shown a large number of patients, treated with multi-kinase inhibitors, being adversely affected by hypertension...
