Laryngopharyngeal reflux as a potential cause of persistent local neck symptoms after total thyroidectomy
2020
Abstract Purpose Local neck symptoms (LNS) may be related to goiter, but are also reported by patients suffering from laryngeal–pharyngeal reflux (LPR). The aim of this study was to investigate whether LPR could play a role in the persistence of some LNS after total thyroidectomy (TT). Methods A consecutive case series of 160 patients with multinodular goiter (MNG) candidate for TT were included in this study. Each patient was closely studied for both the thyroid pathology and reflux disease before and 6 months after surgery to assess the persistence of LNS after surgery. Results Only throat discomfort showed a significant improvement (p = 0.031) after surgery. On the other hand, swallowin…
Multidisciplinary Approach for a Relapsing Goiter with Severe Tracheal Stenosis: A Case Report in an Elderly Patient
2012
Summary Total thyroidectomy is considered the gold standard for thyroid benign pathology treatment. Unfortunately, many partial interventions carried out in the past created many complications due to the tendency of the goiter to relapse and the formation of adherences in the anterior region of the neck. A woman 72 years of age with a relapsing goiter and severe respiratory symptomatology underwent thyroidectomy. After thyroid removal, tracheal stenosis persisted, making the positioning of a T silicon prosthesis (Montgomery’s T-tube) necessary. After 60 days, the prosthesis was replaced with a new made out of the same material but with a larger diameter and a softer consistency, which was r…

Effekt von Calcium und Magnesium auf die Parathormonfreisetzung aus humanem Parathyreoidea-Gewebe in vitro
1982
The effects of calcium and magnesium on parathyroid hormone release from eight adenomas causing primary hyperparathyroidism and six hyperplastic glands causing hypercalcemic secondary hyperparathyroidism were investigated in vitro using single cell suspensions from the respective tissue. We observed suppression of parathyroid hormone release with increasing concentrations of either cation. The quantitative hormone secretions of both adenomatous and hyperplastic glands was identical.
Glycosaminoglycans in Thyroid-Associated Ophthalmopathy
1992
Glycosaminoglycan (GAG) accumulation in the retrobulbar space of patients with thyroid-associated ophthalmopathy (TAO) has been documented in a number of immunohistochemical studies. In order to gain further insight into possible immunopathogenic mechanisms, the influence of humoral immunity on retrobulbar fibroblasts (RF) as GAG producing cells as well as on GAGs themselves was investigated. The effect of lymphocytes on hyaluronic acid (HA) synthesis of RF as well as in turn the influence of RF on lymphocytes were evaluated. In search of methods which would facilitate management of patients with TAO and allow assessment of disease activity, GAGs were determined in both urine and plasma. Im…
Hormonal and nutritional control of L‐carnitine uptake in myoblastic C2C12 cells
2008
L-Carnitine plays an important role in skeletal muscle bioenergetics, and its bioavailability and thus its import may be crucial for muscle function. We studied the effect of thyroid hormone, insulin, and iron overload, hormones and nutrients known to alter muscle metabolism, on L-carnitine import into C2C12 cells. We report here L-carnitine uptake is increased by thyroid hormones and decreased by iron. Insulin was found to be ineffective in altering the L-carnitine uptake.
Hypercalciuria and kidney calcifications in terminal 4q deletion syndrome: Further evidence for a putative gene on 4q
2003
We report a newborn girl with a de novo terminal 4q deletion (q31.3 → qter) and a characteristic phenotype of minor facial anomalies, cleft palate, congenital heart defect, abnormalities of hands and feet, and postnatal onset of growth deficiency. Laboratory studies showed excessive urinary calcium excretion on standard milk formula and on oral calcium load. Blood measurements of parathyroid hormone, calcitonin, bicarbonate, calcium, phosphorus, magnesium, sodium, chlorine, potassium, and urinary measurements of phosphorus, magnesium, sodium, chlorine, potassium were normal for age. At 2 months of life, ultrasonography showed kidney calcifications. Clinical and laboratory data support the d…
Reply to Drs. Kiaei and Molinaro Regarding the Publication “Comparison of a Bridge Immunoassay with Two Bioassays for Thyrotropin Receptor Antibody D…
2020
Dear Editor,Drs. Kiaei and Molinaro 1 put forth two criticisms of the manuscript published by us 2. They state that the experimental design of this study is flawed and that the authors falsely claim that negative Thyretain™ TSI Reporter BioAssay results for two Graves’ diseases patients undergoing drug treatments means the absence of stimulating antibodies. To substantiate this claim Drs. Kiaei and Molinaro point out that the manufacturer of the Thyretain TSI Reporter BioAssay clearly states in the package insert that “[t]he effects of various drug therapies on the performance of this Kit have not been established” 1. Second, the package insert explicitly states that “[a] negative result do…
Does Serum 25-Hydroxyvitamin D Influence Muscle Development during Puberty in Girls? - A 7-Year Longitudinal Study
2013
Vitamin D is well known for its regulatory role in calcium and phosphate homeostasis, but its role in muscle mass and strength during growth remains inconclusive. We explored the association of serum 25-hydroxyvitamin D (25(OH)D) with muscle development in girls from 11 to 18-years old. Whole body lean tissue mass (LMWB), appendicular lean mass (aLM), muscle cross-sectional area at the lower leg (mCSA), maximal voluntary contraction of elbow flexors (MVC elbow) and knee extensors (MVC knee) were assessed in 217 girls aged 10-13 years (at baseline), 215 in 2-year and 226 in 7.5-year follow-up. Serum concentration of 25(OH)D and intact parathyroid hormone (PTH) were analyzed retrospectively a…
Spontaneous bisphosphonate-related osteonecrosis of the left hemi-mandible: Similarities with phossy jaw.
2013
Intravenous bisphosphonates (BP) play a key role in the treatment of bone metastases. As a long-term side effects BP, a form of avascular osteonecrosis of the jaw has been reported. Although, invasive oral local procedures are often present in clinical history of patients suffering from bisphosphonates-related osteonecrosis of the jaws (BRONJ), about up to 50% of BRONJ are spontaneous. We report a case of a 68-year-old female with a spontaneous wide bone sequestration of the left mandibular body onset after infusion of zoledronic acid for 18 cycles for osseous metastasis due to metastatic anaplastic thyroidal carcinoma. Surprisingly the clinical aspects of the patient initially reminded us …
