    Acute thyroiditis is an extremely rare complication of nocardiosis. We report a patient with hyperthyroidism due to suppurative thyroiditis caused by Nocardia brasiliensis. A 38-year-old Black male presented with features of thyrotoxicosis, sepsis and airway obstruction. He had no evidence of underlying thyroid disease, but was severely immunocompromised as a result of acquired immunodeficiency syndrome. He had previously been diagnosed with pulmonary nocardiosis and also had nocardial abscesses on his anterior chest wall. Investigations revealed thyrotoxicosis, with a FT4 of 43.2 pmol/l and a suppressed TSH Nocardia.

    Neonatal suppurative parotitis is very rare. One review of the English-language literature spanning 35 years found only 32 cases. Most cases are managed conservatively with antibiotic therapy; early antibiotic treatment reduces the need for surgery. The predominant organism is Staphylococcus aureus. We report a new case of neonatal suppurative parotitis in a 3-week-old boy. The patient was diagnosed on the basis of parotid swelling, a purulent exudate from a Stensen duct, and the growth of pathogenic bacteria in culture. He responded well to 9 days of intravenous antibiotic therapy. We also discuss the microbiologic and clinical patterns of this disease.

    Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as result of partial or complete obstruction of the bile duct, and may manifest clinically severe form of disease, rapidly deteriorating to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying cause were 12 benign disease(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis(n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients resulting in improvement of general condition and failed in three patients. The procedure were preterminated due to the patient's condition in two and biliary-proto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggest that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment

    This report describes the case of an elderly, diabetic woman who became dehydrated and developed acute suppurative parotitis, which caused marked swelling of her left face and neck. The parotid infection also extended by continuity into the lateral pharyngeal space and contiguous deep neck spaces, causing airway-threatening, extensive inflammation and swelling of the epiglottis and parapharyngeal soft tissues. The differential diagnosis and diagnostic rationale is discussed. The anatomy of the stylomandibular area is reviewed to explain how infection of the parotid can spread to the pharynx.

    Acute obstructive suppurative cholangitis is a well-known clinical entity; however, acute suppuration of the pancreatic duct in the setting of pancreatic ductal obstruction is an uncommon pancreatic disorder. We report a case of acute suppuration of the pancreatic duct without either a concomitant pancreatic abscess or an infected pseudocyst, presenting as acute relapsing pancreatitis. In this case, the underlying cause of suppuration of the pancreatic duct was pancreatic ductal obstruction and chronic pancreatitis secondary to pancreas head carcinoma along with infection of Escherichia coli. Endoscopic placement of a pancreatic stent resulted in an evacuation of grayish thick pus from the distal pancreatic duct with a dramatic improvement of the disease. This case proposes the concept that acute suppuration of the pancreatic duct is a complex process involving the chronically damaged pancreas, pancreatic outflow obstruction, and subsequent bacterial infection. Antibiotic treatment is effective but temporary; therefore, the immediate drainage of the infected pancreatic duct is mandatory.

    Objective: To investigate the effects of vacuum sealing drainage technique in acute and chronic suppurative tenosynovitis of hand. Methods: A total of 9 cases acute and chronic suppurative tenosynovitis patients from January 2013 to April 2015 in Puai Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology were retrospectively reviewed. There were 6 males and 3 females, aging from 27 to 65 years, the average age was 55 years. There were 3 cases of index finger, 3 cases of middle finger, 2 cases of ring finger, 1 case include three fingers. The infection causes included stabbing with fishbone in 3 cases, stabbing with animal bone fragments in 3 cases, wound by sawdust in 3 cases, meat grinder injury in 1 case, multiple fingers crush injury postoperative infection of garbage truck in 1 case. Bacterial infection included 2 cases with Staphylococcus aureus, 2 cases with Staphylococcus epidermidis, 1 case with normal Escherichia coli, 1 case with mixed infection of Enterobacter aerogenes, Klebsiella oxytoca and Staphylococcus, 1 case with Bauman Acinetobacter bacillus, 1 case with Proteus mirabilis and 1 case of no growth of pathogenic bacteria culture. After thorough debridement, vacuum sealing drainage was used to observe the characteristics of irrigation fluid, the formation of cavity inflammation, the prognosis of infection and the recovery of finger function. Results: Seven patients with suppurative tenosynovitis were treated for 7 to 14 days, replaced the vacuum sealing drainage dressing once; 1 patient was an illustration of the finger tip defect flap infected patients after 21 days of treatment, replaced the vacuum sealing drainage dressing twice, 1 patient was an illustration of the central refers to trauma, postoperative infection patients 28 d, replaced three times in the VSD.

    Full Text Available Background/Aim: Pancreatic sepsis secondary to infected necrosis, pseudocyst, or pancreatic abscess is a well-known clinical entity. Acute suppuration of the pancreatic duct (ASPD in the setting of chronic calcific pancreatitis and pancreatic ductal obstruction with septicemia is a rare complication that is seldom reported. It is our aim to report a case of ASPD with Klebsiella ornithinolytica, in the absence of pancreatic abscess or infected necrosis. Case Report: A 46-year-old Asian-Indian man with chronic tropical pancreatitis who was admitted with recurrent epigastric pain that rapidly evolved into septic shock. A CT scan of abdomen revealed a dilated pancreatic duct with a large calculus. Broad-spectrum antibiotics, vasopressors and activated recombinant protein C were initiated. Emergency ERCP showed the papilla of Vater spontaneously expelling pus. Probing and stenting was instantly performed until pus drainage ceased. Repeat CT scan confirmed the absence of pancreatic necrosis or fluid collection, and decreasing ductal dilatation. Dramatic clinical improvement was observed within 36 hours after intervention. Blood cultures grew Klebsiella ornithinolytica. The patient completed his antibiotic course and was discharged. Conclusion: ASPD without pancreatic abscess or infected necrosis is an exceptional clinical entity that should be included in the differential diagnosis of pancreatic sepsis. A chronically diseased pancreas and diabetes may have predisposed to the uncommon pathogen. The presence of intraductal pancreatic stones obstructing outflow played a major role in promoting bacterial growth, suppuration and septicemia. Immediate drainage of the pancreatic duct with endoscopic intervention is critical and mandatory.

    Histological acute appendicitis patterns associated with Enterobius vermicularis is an extremely rare finding. The exact role of this parasite in acute appendicitis is controversial as usually resected specimens show no evidence of histological inflammation. We present herein a case of a 21-year-old male Arabic patient who presented with clinical syndrome of acute appendicitis. Emergency appendectomy was performed and the histopathological examination of the resected specimen showed the presence of E. vermicularis as well as intense acute inflammatory patterns such as mucosal ulceration and suppurative necrosis. The post-operative course was uneventful and the patient was discharged with appropriate anti-helmintic drug prescription. Acute appendicitis due to E. vermicularis is a very rare occurrence. The histopathological analysis of resected specimens should pay special attention to search for this parasite for adequate post-operative treatment of patients.

    The objective of the present study was to elucidate the spectrum of the pathogenic agents responsible for the development of acute suppurative otitis media in the children of the preschool age and to reveal the specific clinical features of this disease depending on its etiological factors. The study involved 138 patients (186 ears) of either sex at the age from 1 year to 84 months who presented with acute suppurative otitis media. The following methods were employed for the purpose of the study: analysis of the patients' complaints and the past medical histories, examination of the ENT organs, microbiological (bacteriological and virological) studies of secretion from the tympanic cavity, diagnostic endoscopy of the nasal cavity and nasopharynx, laboratory investigations. The study allowed to reveal the characteristic clinical manifestations of the pathology of interest depending on its etiology.

    The fibrous variant of Hashimoto thyroiditis is uncommon, accounting for approximately 10% of all cases of Hashimoto thyroiditis. We report a case of this variant that behaved like a malignant neoplasm. The patient was a 69-year-old man who presented with a right-sided anterior neck mass that had been rapidly growing for 2 weeks. Fine-needle aspiration cytology revealed clusters of large multinucleated cells suggestive of an anaplastic carcinoma. A week after presentation, we ruled out that possibility when the mass had shrunk slightly. Instead, we diagnosed the patient with an acute exacerbation of Hashimoto thyroiditis on the basis of laboratory findings. We performed a right thyroid lobectomy, including removal of the isthmus, to clarify the pathology and alleviate pressure symptoms. The final diagnosis was the fibrous variant of Hashimoto thyroiditis, with no evidence of malignant changes. Physicians should keep in mind that on rare occasions, Hashimoto thyroiditis mimics a malignant neoplasm.

  14. A case report of thyroid storm induced by acute sepsis

    Full Text Available Thyroid storm is a rare but life-threatening condition, which can be induced by many critical diseases. We reported a 40-year-old woman with thyroid goiter manifesting with acute sepsis-induced hyperthyroidism. She mainly presented with abdominal bloating, diarrhea, lower limbs edema and exertional dyspnea. The lactate was 9.5 mmol/L and procalcitonin was 3.8 ng/mL, suggesting acute sepsis. The thyroid echo showed bilateral thyroid goiter. Relevant data included a thyroid-stimulating hormone level of 0.03 μIU/mL; free tetraiodothyronine, 5.67 ng/dL; thyroid-stimulating hormone receptor antibody, 76.9% (normal range, < 14%; and antimicrosomal antibody titer, 1:102400 (normal range, < 1:100, suggesting toxic goiter with thyroid storm. Piperacillin/tazobactam, methimazole and Lugol's iodine achieved a good outcome. The symptoms of early sepsis and those of thyroid storm could be similar. Therefore, a careful history taking, a thorough physical examination and a high degree of suspicion could make early diagnosis and appropriate treatment.

    Full Text Available Abstract Background Secondary involvement of the thyroid gland by malignant metastases is uncommon. Acute respiratory crisis due to infiltration of the upper airways is a recognised complication of anaplastic thyroid carcinoma or thyroid lymphoma. Renal cell carcinoma is a tumour that metastasizes diffusely and in an unpredictable manner. Case presentation We report a case of a 73-year-old man with a painful neck mass, dyspnoea, stridor and dysphonia that was evaluated in emergency. A right radical nephrectomy for renal cell carcinoma was performed 8 years previously. An emergency endotracheal intubation was followed by total thyroidectomy. Histological examination confirmed the diagnosis of thyroid metastasis from renal cell carcinoma. Conclusion A literature review regarding emergency treatment for acute respiratory compromise resulting from secondary thyroid tumours was undertaken. Only two cases of metastatic colon cancer and one case of metastatic meningioma requiring emergency thyroidectomy for acute respiratory failure are reported in the literature. This appears to be the first case of emergency surgery performed for acute respiratory compromise due to thyroid metastasis from renal cell carcinoma.

    Full Text Available  Objective  To probe the value of endoscopic retrograde cholangiography (ERC through jejunostomy in patients in whom ERC could not be performed via the mouth after Roux-en-Y anastomosis on the upper gastrointestinal tract. Methods  In two patients suffering from acute obstructive suppurative cholangitis after a radical operation for cholangiocarcinoma, ERC could not be performed through the mouth due to the presence of a long non-functional jejunal loop. A jejunostomy was first done in the afferent loop of the jejunum, and a gastroscope was then inserted via the jejunostomy and passed retrogradely, to find the stoma of the cholangiointestinal anastomosis. ERC was then successfully performed, and followed by endoscopic retrograde biliary drainage (ERBD. Results  The operation was successful. It was found that cholangio-jejunostomy stoma was narrow, and a large amount of purulent mucus was present in the enlarged intrahepatic duct. ERC was done to enlarge the stoma, and a stent was placed into the main branch of the intrahepatic duct. Two patients achieved surgical success and smooth recovery after the operation. Conclusion  ERC through a jejunostomy in the patients who had Roux-en-Y cholangiojejunostomy following radical resection for cholangiocarcinoma, is a safe and effective surgical procedure.

  18. Thyroid hormone receptor β mediates acute illness-induced alterations in central thyroid hormone metabolism.

    2009-05-01

    Acute illness in mice profoundly affects thyroid hormone metabolism in the hypothalamus and pituitary gland. It remains unknown whether the thyroid hormone receptor (TR)-β is involved in these changes. In the present study, we investigated central thyroid hormone metabolism during lipopolysaccharide (LPS)-induced illness in TRβ(-/-) mice compared to wild-type (WT) mice. We administered a sublethal dose of LPS or saline to TRβ(-/-) and WT mice. TRβ(-/-) mice displayed higher basal levels of serum triiodothyronine (T(3)) and thyroxine (T(4)) compared to WT, reflecting thyroid hormone resistance. In the periventricular area of the hypothalamus, we observed a marked decrease in thyrotrophin-releasing hormone (TRH) mRNA expression in TRβ(-/-) and WT mice at t = 4 h, coinciding with the peak in plasma corticosterone. The decrease in TRH mRNA persisted in WT, but not in TRβ(-/-) mice at t = 24 h. By contrast, the increase of type 2 deiodinase (D2) mRNA already present at 4 h after LPS remained significant at 24 h in TRβ(-/-), but not in WT mice. LPS decreased pituitary thyroid-stimulating hormone β mRNA expression in WT at 24 h but not in TRβ(-/-) mice. The peak in pituitary D2 expression at t = 4 h in WT was absent in TRβ(-/-) mice. The relative decrease in plasma T(3) and T(4) upon LPS treatment was similar in both strains, although, at t = 24 h, plasma T(3) tended to be restored in TRβ(-/-) mice. Our results suggest that TRβ is involved in suppression of the central component of the hypothalamic-pituitary-thyroid axis in acute illness.

  19. Acute response of the thyroid to external radiation

    The study showed that the thyroid gland to a measurable degree is acutely influenced by external radiation. Animal experimental studies suggest that the functional reduction mainly is determined by cell loss in mitosis. The transitory fall in RAIU demonstrated in the present study is hardly explainable by cell death or changes in the TSH concentration alone. Part of the explanation could by vascular changes, which may reduce the iodine uptake, but a direct influence on the enzyme systems of the cells may play a role, too. The fall in TSH concentration in the patients irradiated to the neck apparently is not explainable by cell destruction alone either, and the fine-needle aspirates revealed no signs of any essential cell degeneration or destruction. Thus, it must be concluded that the cause of the early fall in TSH concentration is still unexplained. The changes during and immediately after radiotherpy in the thyroid hormone levels suggested a - possibly transient - damage to the thyroid. However, the follow-up study demonstrated that the thyroid function continued its slow decrease. The study tells little about the genesis of the functional changes. In all essentials, the findings are compatible with cell loss due to mitotic death being the main cause of the functional reduction. The fall in the radioiodine uptake and the transient dises in the TSH concentration can hardly be explained by cell loss alone, and the rise in the TSH concentration during the first four months of the study period, too, suggested the possibility of contributory mechanisms.

    Ongoing studies continue. Our initial results indicate that suppurative cholangitis complicating intrahepatic lithiasis has a localized high uptake of Ga-67. Thus, Ga-67 liver scanning can serve as a useful technique for differentiating suppurative cholangitis from nonsuppurative form complicating intrahepatic lithiasis when the patients have the acute attack but without overwhelming sepsis

    2014-10-01

    Full Text Available Objectives: To recall the common clinical presenting features of and guide the diagnostic procedures of primary thyroid lymphomas (PTL. Materials and methods: We report on three patients developing an acute dyspnoea and fast evolving neck mass in the thyroid caused by a PTL occurring in our regional hospital in Switzerland between 2009 and 2013. Results: PTL causes a neck mass, dyspnoea and dysphonia and responds well to chemotherapy. Mortality is due to relapse or infectious complications. Conclusion: Acute dyspnoea caused by thyroid disease is uncommon. Nevertheless, it is the main symptom in PTL due to rapid growth and compression of the airways. Chemotherapy should be started promptly.

    Purpose: Suppurative cholangitis is characterized by obstruction, inflammation, and pyogenic infection of the biliary tract. This disease represents a true emergency. The purpose of this study was to compare the computed tomography (CT) findings between acute calculous suppurative and nonsuppurative cholangitis and to determine if there are findings that assist in the differential diagnosis. Materials and methods: Fifteen patients with acute suppurative cholangitis were enrolled in this study. Findings at endoscopic retrograde cholangiopancreaticography (ERCP) were the standard of reference for suppurative cholangitis. To compare the findings of suppurative cholangitis with those of nonsuppurative cholangitis, 35 patients with nonsuppurative cholangitis were randomly selected. The following findings were evaluated: the presence of papillitis, the presence of stones in the ampulla, the presence of intrahepatic stones, the presence of early inhomogeneous enhancement of the liver, the degree of bile duct dilatation, the degree of bile duct wall thickening and presence of cholecystitis. Sensitivity and specificity for each of the individual findings were calculated. Statistical analyses were performed the Pearson {chi}{sup 2} test, Fisher's exact test and the Mann-Whitney U test. Results: Papillitis showed the highest specificity 86% with 60% sensitivity. Marked inhomogeneous enhancement of the liver during the arterial phase showed 80% specificity with 60% sensitivity. In multivariate logistic analysis, papillitis and marked early inhomogeneous enhancement of the liver were the most significant predictors of acute suppurative cholangitis. The combination of these two CT findings improved specificity (97% specificity) for the diagnosis of suppurative cholangitis. Conclusion: Papillitis and marked early inhomogeneous enhancement of the liver were found to be the most discriminative CT findings for the diagnosis of acute suppurative cholangitis and the

  3. Acute paraparesis as presentation of an occult follicular thyroid carcinoma: A case report

    Directory of Open Access Journals (Sweden)

    José Miguel Baião

    Full Text Available Introduction: Follicular thyroid carcinoma is the second most frequent type of well differentiated thyroid tumours. It is usually confined to the thyroid gland, however it can metastasize in a later stage of the disease. Signs and symptoms associated with bone metastasis are rare as first clinical manifestations. Case report: An 84-year-old female complained with acute paraparesis. Magnetic resonance imaging revealed an extensive intraosseous infiltrating lesion compatible with a bone metastasis from an occult tumour. Biopsy samples were compatible with bone metastasis from a follicular thyroid carcinoma. The patient was submitted to total thyroidectomy followed by iodine ablative therapy. Discussion: Follicular thyroid carcinoma presentation with symptoms related to bone metastasis is rare. Patients with bone lesions, such as pathological fractures or compressive symptoms should be studied since they may have clinically unapparent lesions from an unknown tumour. Patients with FTC should be submitted to total thyroidectomy. Bone lesions may be addressed to improve quality of life however this decision depends on disease extent. Conclusion: Acute paraparesis is a rare form of presentation of thyroid carcinoma. These neoplasms must be taken into account when investigating metastasis to the bone from unknown neoplasms.

    Purpose: The purpose of this study was to assess the efficacy of diffusion-weighted (DW) MR imaging for the differentiation between suppurative lymphadenitis and malignancy in necrotic cervical lymph nodes. Materials and methods: Fifteen patients with suppurative lymphadenitis, 40 with squamous cell carcinoma (SCC), eight with lymphoma, and six with thyroid cancer were accompanied by necrotic cervical nodes. All 69 patients underwent 1.5-T MR imaging including DW and 58 underwent gadolinium-enhanced MR imaging. Necrotic area-to-spinal cord signal intensity ratios (SIR) on T1-, T2- and DW images and apparent diffusion coefficients (ADCs) [10{sup −3} mm{sup 2}/s] were correlated with the pathologies. Results: Nineteen necrotic cervical nodes with suppurative lymphadenitis, 67 with SCC, 10 with lymphoma, and 12 with thyroid cancer were identified. SIR on DW images was higher in suppurative lymphadenitis (2.50 ± 1.21) than in malignancies (1.29 ± 0.67) (p < .01), and ADC value was lower in suppurative lymphadenitis (0.89 ± 0.21) than in malignancies (1.46 ± 0.46) (p < .01). SIR on T1-weighted images was higher in thyroid cancer (1.95 ± 0.53) than in suppurative lymphadenitis (0.87 ± 0.17), SCC (0.92 ± 0.13), and lymphoma (0.95 ± 0.09) (p < .01). No significant difference in SIR on T2-weighted images was found between suppurative lymphadenitis (1.46 ± 0.50) and malignancies (1.61 ± 0.56). Conclusion: DW imaging with ADC measurements may play a supplementary role in the differentiation of necrotic cervical nodes between suppurative lymphadenitis and malignancy.

    Suppurative labyrinthitis continues to result in significant hearing impairment, despite scientific efforts to improve not only its diagnosis but also its treatment. The definitive diagnosis depends on imaging of the inner ear, but it is usually clinically presumed. To analyze the clinical factors and hearing outcomes in patients with labyrinthitis secondary to middle ear infections and to discuss findings based on imaging test results. Retrospective cohort study, based on the charts of patients admitted with middle ear infection-associated labyrinthitis. We identified 14 patients, eight (57%) of whom were females and six (43%) males. Mean age was 40 years. Cholesteatomatous chronic otitis media was diagnosed in six patients (43%), acute suppurative otitis media in six (43%), and chronic otitis media without cholesteatoma was diagnosed in two patients (14%). Besides labyrinthitis, 24 concomitant complications were identified: six cases (25%) of labyrinthine fistula, five cases (21%) of meningitis, five cases (21%) of facial paralysis, five cases (21%) of mastoiditis, two cases (8%) of cerebellar abscess, and one case (4%) of temporal abscess. There was one death. Eight (57%) individuals became deaf, while six (43%) acquired mixed hearing loss. Suppurative labyrinthitis was often associated with other complications; MRI played a role in the definitive diagnosis in the acute phase; the hearing sequel of labyrinthitis was significant.

    Selenium deficiency is a common problem in patients with chronic kidney disease (CKD). This micronutrient has anti-inflammatory and anti-oxidant effects. Selenium is also found in high concentrations in the thyroid gland. To determine the effect of selenium supplementation on thyroid function tests and acute phase reactants in hemodialysis patients. In this double-blinded randomized clinical in 3 months, 64 hemodialysis patients with selenium deficiency were divided into experimental (received selenium supplementation; 32 cases) or control group (received placebo; 32 cases). Erythrocyte sedimentation rate (ESR), ferritin, quantitative C-reactive protein (CRP) and thyroid function tests (TFTs) including thyroid stimulating hormone (TSH), T3 resin uptake (T3RU), and free T4 were measured before and after the intervention and compared between experimental and control groups. At baseline, no significant difference was found between experimental and control groups regarding CRP, ESR and ferritin serum levels. Likewise, after intervention, no significant difference was found between experimental and control groups for CRP (14.77 ± 17.93 vs. 18.29 ± 21.56 mg/L), ESR (32.90 ± 32.62 vs. 33.91 ± 31.15 mm/h) and ferritin (528.6 ± 423.07 vs. 519.52 ± 345.59 ng/mL). At baseline, no significant difference was found between experimental and control groups regarding TFTs. Likewise, after intervention, no significant difference was found between experimental and control groups for TSH (3.7 ± 2.22 vs. 2.84 ± 1.88 µU/mL), free T4 (7.19 ± 1.98 vs. 7.02 ± 1.87 µg/dL) and T3RU (30.04 ± 2.28% vs. 29.2 ± 1.98%). Oral selenium supplementation for three months did not have any significant effect on thyroid function tests or acute phase reactants.

    2015-01-01

    Full Text Available The association between renal dysfunction and hypothyroidism is of increasing clinical importance as thyroid hormone replacement may attenuate decline in renal function and improve cardiovascular outcomes in patients with chronic kidney disease (CKD. Although multiple mechanisms for the induction of renal insufficiency in hypothyroidism have been described, the renal impact of short-term, acute hypothyroidism is unknown, which has possible implications for thyroid cancer patients preparing to receive radioactive iodine (RAI. A 56-year-old gentleman with history of unilateral renal agenesis and CKD stage III presented with intermediate-risk papillary thyroid cancer. In preparation for RAI, he underwent thyroid hormone withdrawal (THW associated with acute kidney injury (AKI, as marked by a decrease in his estimated GFR from 53 to 32 mL/min/1.73 m2. Upon resumption of thyroid hormone, renal function returned to baseline within months. Although AKI in this case was not otherwise associated with adverse outcome and reversed upon resumption of thyroid hormone, it is possible that this phenomenon could result in potential harm, particularly in the patient with baseline renal insufficiency. In CKD patients, preparation for RAI therapy may require special consideration; future studies should address the role of recombinant TSH to mitigate deleterious renal effects of acute hypothyroidism in this setting.

    Full Text Available Changes in thyroid hormone levels, mostly as non-thyroidal illness syndrome (NTIS, have been described in many diseases. However, the relationship between acute liver failure (ALF and thyroid hormone levels has not yet been clarified. The present study evaluates potential correlations of select thyroid functional parameters with ALF.84 consecutively recruited ALF patients were grouped according to the outcome of ALF (spontaneous recovery: SR; transplantation or death: NSR. TSH, free thyroxine (fT4, free triiodothyronine (fT3, T4, and T3 were determined.More than 50% of patients with ALF presented with abnormal thyroid parameters. These patients had greater risk for an adverse outcome than euthyroid patients. SR patients had significantly higher TSH, T4, and T3 concentrations than NSR patients. Albumin concentrations were significantly higher in SR than in NSR. In vitro T3 treatment was not able to rescue primary human hepatocytes from acetaminophen induced changes in mRNA expression.In patients with ALF, TSH and total thyroid hormone levels differed significantly between SR patients and NSR patients. This might be related to diminished liver-derived transport proteins, such as albumin, in more severe forms of ALF. Thyroid parameters may serve as additional indicators of ALF severity.

  15. A Case of Airway Obstruction Secondary to Acute Haemorrhage into a Benign Thyroid Cyst

    2014-01-01

    Full Text Available A 70-year-old female, with a history of progressive dyspnoea, was admitted to the critical care unit after successful resuscitation following a witnessed, out of hospital cardiorespiratory arrest. A presumptive diagnosis of cardiorespiratory arrest secondary to an exacerbation of chronic obstructive pulmonary disease was made. However, on more detailed examination a large anterior, midline neck mass was noted. Following tracheal intubation, a computerised tomography scan of the patient’s neck and thorax revealed a seven-centimetre, well-defined, nonenhancing, rounded homogeneous opacity at the thoracic inlet, consistent with a large midline thyroid cyst. Needle aspiration of the cyst was performed and yielded approximately 50 mL of frank blood. After an uncomplicated tracheal extubation and recovery, an elective subtotal thyroidectomy was performed prior to hospital discharge. Histology of the specimen revealed a benign thyroid cyst within a multinodular goitre. Euthyroid multinodular goitres are more likely to be managed conservatively due to an asymptomatic clinical course in most patients. However, the risk of respiratory distress and acute airway obstruction from tracheal compression or acute haemorrhage should be kept in mind. Patients at risk of this life threatening complication should be managed with elective thyroidectomy to reduce morbidity and mortality.

    Glutathione peroxidase activities and malondialdehyde levels were measured in the homogenated anterior segment of rat eyes with endotoxin induced acute anterior uveitis in euthyroid, hyperthyroid and hypothyroid rats. Malondialdehyde concentrations were found to be significantly increased (p 0.05). These results suggest that excess or deficiency of the thyroid hormones cause alterations in the malondialdehyde levels and glutathione peroxidase activities of the rat eyes in endotoxin induced uveitis, and hyperthyroidism may increase the oxidative stress in endotoxin induced acute anterior uveitis.

    Full Text Available In addition to listeriosis which is relatively common in ruminants, there are three other uncommon suppurative intracranial processes (SIP identifiable in adult ungulates as brain abscess, basilar empyema and suppurative meningitis. The present paper reports the epidemiological, clinical, laboratorial, pathological and microbiological findings of 15 domestic ruminants with SIP. A total of 15 animals were selected (eight sheep, four cattle and three goats; with the definitive diagnoses of basilar empyema (n=3, brain abscess (n=1, listeriosis (n=5 and suppurative meningitis (n=6. Hematology revealed leukocytosis with inversion of the lymphocyte/ neutrophil ratio in 4 cases. In the majority of animals, cerebrospinal fluid (CSF presented light yellow coloration and cloudy aspect due to neutrophilic pleocytosis (15 - 997 leukocytes/µL. Microbiological culture of CSF or central nervous system (CNS fragments resulted on isolation of Trueperella (Arcanobacterium pyogenes,Listeria monocytogenes,Escherichia coli and Stenotrophomonas sp. In a goat with thalamic abscess, microbiological assay was not performed, but Gram positive bacilli type bacteria were observed in histology. The diagnosis of these outbreaks was based on the association of epidemiological, clinical, pathological and bacteriological findings; reiterating that the infectious component remains an important cause of CNS disease in domestic ruminants and also shows the need for dissemination of information about the most effective preventive measures for the ranchers.

    To compare retrospectively serum levels of thyroid hormones (THs) and thyroid stimulating hormone (TSH) between patients with biliogenic acute pancreatitis (BAP) and those with hyperlipidaemic acute pancreatitis (HLAP), in order to assess their value for predicting the severity of acute pancreatitis (AP). Patients with AP were divided into BAP and HLAP groups, then further divided into either a mild AP (MAP) group or a moderately severe AP (MSAP) group. Routine blood parameters were measured. Free tri-iodothyronine (FT3), free thyroxine (FT4) and TSH levels were measured. Seventy-six patients with AP were enrolled in the study. FT3 and TSH levels were significantly higher in patients with MAP than in patients with MSAP. FT4 and TSH levels were significantly lower in the HLAP group than in the BAP group. TSH levels in both MAP and MSAP patients were significantly lower in the HLAP group than in the BAP group. TSH was inversely correlated with triglyceride levels in patients with HLAP. FT3 was a risk factor for MSAP in patients with AP and also demonstrated moderate accuracy in predicting AP severity. THs and TSH decrease with the severity of AP, especially in patients with HLAP. FT3 may be a useful biomarker for the early assessment of the severity of AP. © The Author(s) 2016.

    Full Text Available Objective To explore the correlation between thyroid hormone levels in patients with acute ischemic stroke and the severity of disease and short-term prognosis. Methods According to the level of serum total triiodothyronine (TT3, 98 patients who presented first acute ischemic stroke and without history of thyroid abnormality were divided into low TT3 group and normal TT3 group. Thyroid hormone levels and neurological function defect of those patients were tested, and their neural functional recovery after 3 months was evaluated.  Results Low TT3 group had more severe neural function defect compared to normal TT3 group (χ2 = 58.134, P = 0.000. There were no significant differences on total thyroxine (TT4; t = 1.636, P = 0.105 and thyroid stimulating hormone (TSH; t = 1.059, P = 0.292 between 2 groups. There was a significantly negative correlation between TT3 levels and National Insititute of Health Stroke Scale (NIHSS score on admission (r = -0.672, P = 0.000. Patients with low TT3 showed a significantly smaller percentage of neurological function improvement on both NIHSS ( χ2 = 8.993, P = 0.003 and modified Rankin Scale (mRS; χ2 = 6.247, P = 0.012 scores compared to those with normal TT3 at 90 d after onset.  Conclusions Low T3 level is associated with the severity of acute ischemic stroke and neural functional recovery, suggesting serum T3 level may be a predictor of neural function improvement in patients with acute ischemic stroke. DOI: 10.3969/j.issn.1672-6731.2015.02.009

    Full Text Available BACKGROUND Chronic Suppurative Otitis Media (CSOM refers to a chronic inflammatory condition of the middle ear and mastoid cavity. There is acute inflammation of middle ear leading to irritation and then inflammation of the mucosa producing oedema. Breakdown of the epithelium causes ulceration subsequent infection and formation of granuloma/granulation tissue. Granuloma formation leads to the development of polyps in middle ear. Factors influencing development of complications are, age, low socio-economic status, virulence of organism, immune compromised host, previous surgeries, fractures, fistulas, cholesteatoma. The complications developed spread through various modes like direct bone erosion, thrombophlebitis, preformed pathways, congenital bony defects, sutures of skull that remains patent, old fractures-heal by fibrosis, defects caused by surgery, oval and round windows, infection from labyrinth. The extracranial complications which can be encountered in chronic suppurative otitis media are, acute mastoiditis, petrositis, facial nerve palsy, labyrinthitis and discharging sinuses. MATERIALS AND METHODS Sample size for the present study was fifty four. This study was done in the Department of ENT, Travancore Medical College, Kollam. This study was done from January 2015 To January 2016. Detailed clinical history was taken and the clinical examination was conducted. The extracranial complications were noted and reported. RESULTS In the present study, maximum number of cases belonged male sex which was thirty eight cases. Sixteen cases belonged to female sex. Maximum number of cases which amounted to forty one in number belonged to age group zero to twenty years, followed by age group twenty to forty years which amounted to eleven cases, followed by age group forty to sixty which amounted to two cases. No cases were reported in age group more than sixty years in our study. Based on socioeconomic data, maximum number of cases belonged to low

    Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20% are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a final diagnosis of multiple endocrine neoplasia with pheochromocytoma and medullary thyroid carcinoma (MTC).

    The aim of this study was to investigate the 4977 and 7400 bp deletions of mitochondrial DNA in patients with chronic suppurative otitis media and to indicate the possible association of mitochondrial DNA deletions with chronic suppurative otitis media. Thirty-six patients with chronic suppurative otitis media were randomly selected to assess the mitochondrial DNA deletions. Tympanomastoidectomy was applied for the treatment of chronic suppurative otitis media, and the curettage materials including middle ear tissues were collected. The 4977 and 7400 bp deletion regions and two control regions of mitochondrial DNA were assessed by using the four pair primers. DNA was extracted from middle ear tissues and peripheral blood samples of the patients, and then polymerase chain reactions (PCRs) were performed. PCR products were separated in 2 % agarose gel. Seventeen of 36 patients had the heterozygote 4977 bp deletion in the middle ear tissue but not in peripheral blood. There wasn't any patient who had the 7400 bp deletion in mtDNA of their middle ear tissue or peripheral blood tissue. The patients with the 4977 bp deletion had a longer duration of chronic suppurative otitis media and a higher level of hearing loss than the others (p otitis media and the reactive oxygen species can cause the mitochondrial DNA deletions and this may be a predisposing factor to sensorineural hearing loss in chronic suppurative otitis media. An antioxidant drug as a scavenger agent may be used in long-term chronic suppurative otitis media.

    Although hidradenitis suppurativa is a common and serious skin condition, its treatment is not well established. It is now accepted that the moderate and severe forms of the disease are associated with marked systemic inflammation. The goal of treatment in hidradenitis suppurative is therefore to achieve systemic control of inflammation. In some cases, surgery may also be necessary to reduce the severity of the manifestations of cutaneous inflammation. Recent advances in our understanding of hidradenitis suppurativa have been accompanied by the emergence of novel approaches to its treatment, including the use of certain biologic drugs. Several clinical trials have been undertaken to test the effects of biologics (mainly adalimumab) in this setting. In this review, we analyze the different treatments available for hidradenitis suppurativa. Copyright © 2015 Elsevier España, S.L.U. and AEDV. All rights reserved.

  12. THYROID HORMONE REVERSES AGING-INDUCED MYOCARDIAL FATTY ACID OXIDATION DEFECTS AND IMPROVES THE RESPONSE TO ACUTELY INCREASED AFTERLOAD

    Energy Technology Data Exchange (ETDEWEB)

    Ledee, Dolena; Portman, Michael A.; Kajimoto, Masaki; Isern, Nancy G.; Olson, Aaron

    2013-06-07

    Background: Subclinical hypothyroidism occurs during aging in humans and mice and may contribute to development of heart failure. Aging also impairs myocardial fatty acid oxidation, causing increased reliance on flux through pyruvate dehydrogenase (PDH) to maintain function. We hypothesize that the metabolic changes in aged hearts make them less tolerant to acutely increased work and that thyroid hormone reverses these defects. Methods: Studies were performed on young (Young, 4-6 months) and aged (Old, 22-24 months) C57/BL6 mice at standard (50 mmHg) and high afterload (80 mmHg). Another aged group received thyroid hormone for 3 weeks (Old-TH, high afterload only). Function was measured in isolated working hearts along with substrate fractional contributions (Fc) to the citric acid cycle (CAC) using perfusate with 13C labeled lactate, pyruvate, glucose and unlabeled palmitate and insulin. Results: Cardiac function was similar between Young and Old mice at standard afterload. Palmitate Fc was reduced but no individual carbohydrate contributions differed. CAC and individual substrate fluxes decreased in aged. At high afterload, -dP/dT was decreased in Old versus Young. Similar to low afterload, palmitate Fc was decreased in Old. Thyroid hormone reversed aging-induced changes in palmitate Fc and flux while significantly improving cardiac function. Conclusion: The aged heart shows diminished ability to increase cardiac work due to substrate limitations, primarily impaired fatty acid oxidation. The heart accommodates slightly by increasing efficiency through oxidation of carbohydrate substrates. Thyroid hormone supplementation in aged mice significantly improves cardiac function potentially through restoration of fatty acid oxidation.

    Osseous and joint manifestations (decalcification, osteolysis, osteonecrosis; poliarthrytis; periarticular fat necrosis) are sometimes encountered in chronic pancreatitis or carcinoma, but exceptional after severe acute pancreatitis, especially infected pancreatic necrosis. Pathogenesis of calcium deficiency in acute pancreatitis is multifactorial, including extensive lipolysis and metabolic disturbances. We report on a healthy, young male, that developed decalcification and polyarthritis consecutive to a long-outcome, severe acute pancreatitis. We comment upon hypocalcemia, as a rare complication of acute pancreatitis.

    Full Text Available This study evaluated the effects of acute high-dose and chronic lifetime exposure to alcohol and exposure patterns on the development of differentiated thyroid cancer (DTC.The Thyroid Cancer Longitudinal Study (T-CALOS included 2,258 DTC patients (449 men and 1,809 women and 22,580 healthy participants (4,490 men and 18,090 women who were individually matched by age, gender, and enrollment year. In-person interviews were conducted with a structured questionnaire to obtain epidemiologic data. Clinicopathologic features of the patients were obtained by chart reviews. Odds ratios (ORs and 95% confidence intervals (95%CI were estimated using conditional regression models.While light or moderate drinking behavior was related to a reduced risk of DTC, acute heavy alcohol consumption (151 g or more per event or on a single occasion was associated with increased risks in men (OR = 2.22, 95%CI = 1.27-3.87 and women (OR = 3.61, 95%CI = 1.52-8.58 compared with never-drinkers. The consumption of alcohol for 31 or more years was a significant risk factor for DTC for both men (31-40 years: OR = 1.58, 95%CI = 1.10-2.28; 41+ years: OR = 3.46, 95%CI = 2.06-5.80 and women (31-40 years: OR = 2.18, 95%CI = 1.62-2.92; 41+ years: OR = 2.71, 95%CI = 1.36-5.05 compared with never-drinkers. The consumption of a large amount of alcohol on a single occasion was also a significant risk factor, even after restricting DTC outcomes to tumor size, lymph node metastasis, extrathyroidal extension and TNM stage.The findings of this study suggest that the threshold effects of acute high-dose alcohol consumption and long-term alcohol consumption are linked to an increased risk of DTC.

    A review of the treatment of pediatric acute mastoiditis requiring surgical intervention managed with and without PICC therapy postoperatively. Retrospective study of 42 cases from 1989 to 2004 treated at a regional children's hospital. Sixteen patients received postoperative PICC therapy and 26 received a course of oral antibiotics. The PICC group received on average 12.12 days of intravenous antibiotics compared to only 3.53 days for the non-PICC group (P PICC group. There were no surgical complications. The total cost for outpatient PICC therapy increased treatment costs by approximately $1500 to $2500. Oral antibiotic therapy is sufficient after surgical intervention for acute pediatric suppurative mastoiditis without intracranial complications and does not result in adverse treatment outcome. Use of PICC therapy after surgical intervention for mastoiditis should be limited. B-3b.

    2013-01-01

    Although thyroid dysfunction will develop in more than 12% of the US population during their lifetimes, true thyroid emergencies are rare. Thyroid storm and myxedema coma are endocrine emergencies resulting from thyroid hormone dysregulation, usually coupled with an acute illness as a precipitant. Careful assessment of risk and rapid action, once danger is identified, are essential for limiting morbidity and mortality related to thyroid storm and myxedema coma. This article reviews which patients are at risk, explains thyroid storm and myxedema coma, and describes pharmacological treatment and supportive cares.

  9. Does 131I-treatment of goitre result in an acute increase in the volume a function of the thyroid gland?

    International Nuclear Information System (INIS)

    1995-01-01

    Many textbooks claim that radioiodine ( 131 I) treatment should be avoided in treatment of a goitre with substernal extension, due to fear of acute swelling of the gland with resulting respiratory problems. We examined patients with multinodular goitre, either nontoxic (n=20) or toxic (n=10) after treatment with 131 I. An ultrasonically determined thyroid volume and thyroid function variables were investigated before and two, seven, 14, 21, 28 and 35 days after treatment. In nontoxic goitres the thyroid volume did not increase significantly, the maximum increase in the median volume being 4% on day 7. Serum levels of free T 3 and free T 4 indices increased by 20% (day 7) and 13% (day 14) (p=0.002), respectively. Likewise thyroid volume in toxic nodular goitre did not change significantly after 131 I treatment. None of the patients presented symptoms of tracheal compression. We conclude that 131 I treatment of nontoxic as well as toxic multinodular goitre does not seem to increase thyroid volume. (au) 18 refs

  10. Acute changes of peripheral thyroid hormone concentrations and serum thyroglobulin during radio-iodine therapy

    International Nuclear Information System (INIS)

    1986-01-01

    TT3, FT3 and FT4 concentrations were measured in 28 patients with hyperthyroidism before and during therapy with radioiodine. In addition, in some patients serum thyroglobulin was evaluated, too. Only in the patients with immunogenic hyperthyroidism FT3, FT4 and serum TG were elevated significantly within the first two days after radioiodine application. In the residual patients with diffuse autonomy, autonomous adenoma, and multifocal autonomy during the whole time of investigation there was no significant increase of the respective values. From these data it can be deducted that hyperthyroid storm is more likely to be provoked in patients with immunogenic hyperthyroidism compared to thyroidal autonomy. (orig.) [de

    Polk, D.H.; Wu, S.Y.; Fisher, D.A.

    1986-08-01

    After either total thyroidectomy or sham operation in full-term fetal sheep, fetuses were delivered and serial blood samples were obtained for measurements of thyroxine (T4), triiodothyronine (T3), and catecholamines. Despite comparable serum T4 values, serum T3 values were lower in the thyroidectomized animals. Four hours after birth, the animals were killed with an intravenous overdose of barbiturate. Brain, thyroid, liver, kidney, and brown adipose tissues were dissected and analyzed for thyroxine 5'-monodeiodinase (5'-MDI) activity in vitro. 5'-MDI activity was comparable in all tissues from sham-operated and thyroidectomized lambs. Plasma epinephrine and norepinehprine concentrations, mean arterial pressure, mean pulse, rectal temperature, and arterial blood gas values were similar in the two groups of animals. These data support the hypothesis that the thyroid gland is the major source of T3 for the T3 surge in the immediate newborn period. They also indicate that the neonatal T3 surge has limited immediate metabolic significance in euthyroid newborns.

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    Full Text Available Osteomyelitis is an infection of the bone or bone marrow, usually caused by pyogenic bacteria or mycobacterium. Osteomyelitis, inflammatory process of the bone and its structures, can be acute or chronic. Taking a journey from a nonsurgical approach to a surgical one, it appeared to be one osteomyelitis revenge against all our efforts. The pain, the pus, the new bone formation, and all the trouble, this case showed it all. The injudicious use of antibiotics and delay in providing the requisite treatment can cause devastating effects as in the case of an 11-year-old child. A case report on treating osteomyelitis through medication and realizing that surgical excision remains the only realistic approach, the report talks about the investigations and treatment planning done to deal with it.

    This study was done retrospectively to analyze the ultrasonographic (US) findings in thyroid scintigraphic hot areas (HA). Three-thousand, eight-hundred and thirty-nine consecutive patients who underwent {sup 99m}Tc-pertechnetate (n=3435) or {sup 123}I (n=457) scintigraphy were analyzed. HA were regarded as present when the tracer concentration was greater than the remaining thyroid tissue, or when hemilobar uptake was observed. High-resolution US examinations were performed with a real-time electronic linear scanner with a 7.5 or 10 MHz transducer. One hundred and four (2.7%) were found to be scintigraphic HA (n=120). US revealed a nodular lesion or well-demarcated thyroid tissue corresponding to the HA in 94 areas (78.4%, Category 1), an ill-defined region with different echogenicity in 13 areas (10.8%, Category 2), and no correlating lesion in 13 areas (10.8%, Category 3). These 104 patients included 43 with adenomatous goiter (59 areas), 33 with adenoma, 11 with Hashimoto's thyroiditis, 5 with primary thyroid cancer, 4 with euthyroid ophthalmic Graves' disease (EOG), 3 with hemilobar atrophy or hypogenesis, 2 with hemilobar agenesis, 2 with hypothyroidism with blocking-type TSH-receptor antibodies (TSHRAb), 1 with acute suppurative thyroiditis. Among the 59 adenomatous nodules and 33 adenomas, 51 (86.4%) and 32 (97.0%), respectively, belonged to Category 1. A solitary toxic nodule was significantly larger and occurs more often in older patients than in younger patients. On the other hand, all 17 patients with known autoimmune thyroid diseases including Hashimoto's thyroiditis, EOG and hypothyroidism with blocking TSHRAb belonged to Category 2 or 3. Possible underlying mechanisms are hyperfunctioning tumors or nodules, localized functioning thyroid tissue freed from autoimmune destruction, inflammation or tumor invasion, congenital abnormality, clusters of hyperactive follicular cells caused by long-term TSH and/or TSHRAb stimulation, asymmetry

    Cystatin C (Cysc) could be affected by thyroid function both in vivo and in vitro and thereby may have limited ability to reflect renal function. We aimed to assess the association between Cysc and thyroid hormones as well as the effect of thyroid function on the diagnostic accuracy of Cysc to detect acute kidney injury (AKI). A total of 446 consecutive intensive care unit (ICU) patients were screened for eligibility in this prospective AKI observational study. Serum Cysc, thyroid hormones and serum creatinine (Scr) were measured upon entry to the ICU. We also collected each patient's baseline characteristics including the Acute Physiology and Chronic Health Evaluation II (APACHE-II) score. The diagnostic performance of Cysc was assessed from the area under the receiver operator characteristic curve (AUC) in each quartile of thyroid hormone(s). A total of 114 (25.6%) patients had a clinical diagnosis of AKI upon entry to the ICU. The range of free thyroxine (FT4) value was 4.77 to 39.57 pmol/L. Multivariate linear regression showed that age (standardized beta = 0.128, P Patients were divided into four quartiles based on FT4 levels. The AUC for Cysc in detecting AKI in each quartile were as follows: 0.712 in quartile I, 0.754 in quartile II, 0.829 in quartile III and 0.797 in quartile IV. There was no significant difference in the AUC between any two groups (all P > 0.05). The optimal cut-off value of Cysc for diagnosing AKI increased across FT4 quartiles (1.15 mg/L in quartile I, 1.15 mg/L in quartile II, 1.35 mg/L in quartile III and 1.45 mg/L in quartile IV). There was no significant impact of thyroid function on the diagnostic accuracy of Cysc to detect AKI in ICU patients. However, the optimal cut-off value of Cysc to detect AKI could be affected by thyroid function.

    The aim of the present study was to evaluate the role of hypothyroidism as a cause of hyponatremia in a clinical model of iatrogenic acute hypothyroidism due to thyroid hormone withdrawal prior to ablative radioactive iodine (RAI) therapy after total thyroidectomy. The study group consisted of 101 differentiated thyroid cancer (DTC) patients (77 women and 24 men). Plasma concentration of thyroid-stimulating hormone ([TSH]) and sodium ([Na + ]) was evaluated before total thyroidectomy (pre[TSH] and pre[Na + ]) and on the day of RAI therapy (post[TSH] and post[Na + ]). The frequency of hypothyroidism-associated hyponatremia was 4 % (4/101). Pre[Na + ] was significantly higher than post[Na + ] (140.7 ± 1.6 vs 138.7 ± 2.3 mEq/L, p = 0.012). Moreover, a linear correlation was identified between pre[Na + ] and post[Na + ]. Iatrogenic acute hypothyroidism-related hyponatremia is uncommon. However, because of the significant reduction of [Na + ] in the transition from euthyroidism to iatrogenic hypothyroidism, the value of pre[Na + ] should be viewed as a parameter to be considered. Since it acts as an independent risk factor for the development of hyponatremia, patients with a pre[Na + ] close to the lower limit of normal range may deserve a closer monitoring of [Na + ].

  3. Acute Zonal Occult Outer Retinopathy (AZOOR in a patient with Hashimoto's thyroiditis

    Directory of Open Access Journals (Sweden)

    Luiz Reis Barbosa Júnior

    Full Text Available ABSTRACT Acute zonal occult outer retinopathy (AZOOR is a rare disease characterized by an acute damage of one or more external retinal zones leading to the visual field or the visual acuity impairment associated with small or no changes in the fundus examination.The main clinical symptoms are scotomas and the sudden onset of photopsias. Abnormal findings on electroretinography and visual field defects are critical for the diagnosis. Central vision is usually preserved and the stabilization occurs in six months in most cases. The objective of this article is to describe a 24-month follow-up of a patient with AZOOR and correlate the findings with the typical features of this disease.

    2012-03-01

    PAPA syndrome is a recently identified hereditary autoinflammatory syndrome clinically characterized by pyogenic arthritis, severe acne, and pyoderma gangrenosum. It is caused by mutations in the PSTPIP1 gene and may be closely linked to the aseptic abscesses syndrome, which has been shown to be associated with CCTG repeat amplification in the promoter region of PSTPIP1. We describe two unrelated patients with a clinical presentation quite similar to, yet distinct from, PAPA syndrome. Both patients had pyoderma gangrenosum and acute or remittent acne conglobata, but, in contrast to PAPA syndrome, lacked any episodes of pyogenic arthritis. Instead, they had suppurative hidradenitis. Mutations in PSTPIP1 exons 1 to 15 were excluded. In the promoter region, an increased repetition of the CCTG microsatellite motif was present on one allele in both patients. Alterations of the most commonly affected exons of the MEFV, NLRP3, and TNFRSF1A genes also were not detectable. One patient was treated with the interleukin (IL)-1 receptor antagonist anakinra and responded well, although without complete remission. This implies that IL-1ß may be of pathogenetic importance. Small number of patients, no gene mutation identified, and unclear efficacy of therapy are limitations. The clinical triad of pyoderma gangrenosum, acne, and suppurative hidradenitis represents a new disease entity within the spectrum of autoinflammatory syndromes, similar to PAPA and aseptic abscesses syndrome. For this disease, we propose the acronym "PASH" syndrome. PASH syndrome may respond to IL-1ß blockade. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    Hidradenitis Suppurative-Acne Inversa is one of the most debilitating chronic skin diseases. It seriously affects the emotional and relational life of the patient, it has a significant psychiatric comorbidity and it impairs the quality of life. We present the report of a clinical situation with onset of the illness in a young woman during pregnancy, a case characterized by particular evolution, severe systemic involvement, strong psycho-emotional impact on the patient and impairment of subjective well-being of the caregiver. The clinical evaluation highlights mainly the relevance of the bodily experience, that stands out as a central issue in the sufference of the patient. She feels an uncanny foreignness to herself and a lacerating wound of her identity, related to her desirability, her femininity and her motherhood. Specific personality factors, which are likely to have influenced and guided the experience of illness and the quality of the relationship with the treatment team, are also evaluated. This case exemplifies, at different levels, the clinical complexity of Hidradenitis Suppurative-Acne Inversa and its impact on individual subjectivity. This disease requires an integrated intervention by a multidisciplinary team, providing for the assessment, the treatment and the evaluation of outcomes. It is necessary an effective operational link between different competences, in order to promote the patient compliance and to activate and develop the best care and the right psychological support.

    2001-01-01

    Observational studies indicate a high prevalence of hypothyroidism in the general hypertensive population. Cardiac output and peripheral resistances are influenced by triiodothyronine (T3), which has both and inotropic and vasodilatory effect. T3 also stimulates sympathetic activity, increases angiotensinogen and atrial natriuretic peptide and respectively decreases vasopressin levels. In the kidney, it increases GFR and decreases sodium reabsorption. We here report the first preliminary results (phase 1: acute effects) of a study aimed to investigate a possible role of renal haemodynamic modifications in the relationships between hypothyroidism and arterial hypertension. We studied six hypertensive patients with no renal disease and normal serum creatinine. Tc99m-DTPA scintigraphy was made twice, respectively before and 1.5-2 hrs after oral T3 (40μg) and GFR evaluated by the Gates method. Plasma free T3 increased in all the subjects (from 2.45±69 to 8.30±2.35 pg/ml, means ±SD), whereas lesser variations were observed for GFR (from 84.50±32.99 to 91.17±38.60ml/min). Definite data will be presented after having investigated a larger series of patients who are currently under recruitment. The results will possible clarify if T3 has either and immediate direct haemodynamic effect on GFR or rather a delayed 'genomic' effect (au)

RESULTS From our study, we found mainly children of age group 10-11 years commonly affected. They belong to poor socioeconomic background. Pseudomonas aeruginosa is the most common organism isolated in the present study. Ciprofloxacin was found to be the most sensitive antibiotic to Pseudomonas aeruginosa. CONCLUSION We noticed that drug resistance is on the rise due to misuse of antibiotics, over-the-counter treatment, inadequate period of therapy and less awareness among public regarding drug resistance. Constant monitoring of antibiotic sensitivity is needed to prevent drug resistance in CSOM.

    Exposure of the thyroid gland to ionizing radiation has been associated with a variety of abnormalities. Among these are tardive hypothyroidism and an increased risk of developing thyroid nodules and cancer. Although acute thyroiditis has been known to complicate radioactive iodine 131 therapy, it has rarely been associated with external beam irradiation. Thyrotoxic painless thyroiditis developed in two patients after mantle-field irradiation for Hodgkin's disease

    A 6-year-old female Parma wallaby (Macropus parma) at a zoo in California developed acute ataxia and left-sided circling. Despite intensive care, clinical signs progressed to incoordination and prostration, and the animal was euthanized. At necropsy, the left tympanic cavity was filled with homogeneous suppurative exudate that extended into the cranium expanding the meninges and neuroparenchyma in the lateral and ventral aspect of the caudal ipsilateral brainstem and medulla oblongata. Microscopically, the brainstem showed regional severe suppurative meningoencephalitis with large numbers of neutrophils, fewer macrophages, and lymphocytes admixed with fibrin, necrotic cellular debris, hemorrhage, and mineralization, with numerous intralesional Gram-negative bacilli. Bacteroides spp. and Porphyromonas spp. were isolated on anaerobic culture from the meninges, and the bacteria were further characterized by partial 16S ribosomal RNA gene sequencing as Bacteroides tectus and Porphyromonas gulae. Bacterial aerobic culture from the meninges yielded very low numbers of mixed flora and Proteus spp., which were considered contaminants. Culture of Mycoplasma spp. from middle ear and meninges was negative. Additionally, Toxoplasma gondii cysts were detected by immunohistochemistry in the heart and brain, and anti-Toxoplasma antibodies were detected in serum. The genera Bacteroides and Porphyromonas have been associated with oral disease in marsupials; but not with otitis and meningoencephalitis. The results of the present work highlight the importance of performing anaerobic cultures in the diagnostic investigation of cases of suppurative otitis and meningoencephalitis in macropods. © 2014 The Author(s).

    Synthetic pyrethroids (SPs) have the potential to disrupt the thyroid endocrine system in mammals; however, little is known of the effects of SPs and underlying mechanisms in fish. In the current study, embryonic zebrafish were exposed to various concentrations (1, 3 and 10 μg/L) of bifenthrin (BF) or λ-cyhalothrin (λ-CH) until 72 h post fertilization, and body condition, bioaccumulation, thyroid hormone levels and transcription of related genes along the hypothalamus–pituitary–thyroid (HPT) axis examined. Body weight was significantly decreased in the λ-CH exposure groups, but not the BF exposure groups. BF and λ-CH markedly accumulated in the larvae, with concentrations ranging from 90.7 to 596.8 ng/g. In both exposure groups, alterations were observed in thyroxine (T{sub 4}) and triiodothyronine (T{sub 3}) levels. In addition, the majority of the HPT axis-related genes examined, including CRH, TSHβ, TTR, UGT1ab, Pax8, Dio2 and TRα, were significantly upregulated in the presence of BF. Compared to BF, λ-CH induced different transcriptional regulation patterns of the tested genes, in particular, significant stimulation of TTR, Pax8, Dio2 and TRα levels along with concomitant downregulation of Dio1. Molecular docking analyses revealed that at the atomic level, BF binds to thyroid hormone receptor (TRα) protein more potently than λ-CH, consequently affecting HPT axis signal transduction. In vitro and in silico experiments disclosed that during the early stages of zebrafish development, BF and λ-CH have the potential to disrupt thyroid endocrine system. - Highlights: • Following respective exposure of embryos to BF and λ-CH, thyroid endocrine disruption was investigated in zebrafish embryos. • Thyroid hormones (T3 and T4 levels) were significantly altered after being exposed to BF and λ-CH. • Gene transcription modulation in the HPT axis was examined. • BF and λ-CH bioconcentration in zebrafish larvae were evident. • BF binds to thyroid

    Full Text Available Introduction: Surgically treated intracranial suppurations (ICS are uncommon, life-threatening neurosurgical emergencies. They can result from complication of chronic suppurative otitis media (CSOM and bacterial rhinosinusitis (BRS. The objective of this study was to know the frequency of BRS and CSOM and relate it to its rare complication of surgically treated ICS while also describing the demography, type and outcome of ICS that resulted from BRS and CSOM. Materials and Methods: All patients that presented to the Otorhinolaryngological department and Neurosurgical unit of the same institution with clinical and radiological features of CSOM, BRS, and ICS were prospectively studied over a 5-year period. Patients were followed up for a minimum of 3 months. Results: Two thousand, two hundred and seventy-nine patients presented during the 5-year study period. Of all these patients, 1511 had CSOM (66.3% and 768 (33.7% presented with features of BRS. Eleven (0.73% had ICS complicating their CSOM while 8 (1.04% cases of surgically treated ICS followed BRS. Bacterial rhinosinusitis was not more likely to lead to ICS (P = 0.4348. The Odds ratio (OR of a child ≤ 18 years of age with CSOM developing ICS was 5.24 (95% Confidence interval 1.13-24.34; P = 0.0345, while it was 7.60 (95% Confidence interval 1.52-37.97; P = 0.0134 for children with BRS. Conclusions: The most common type of ICS complicating CSOM and BRS was brain abscess and subdural empyema, respectively. Children are more prone to develop surgical ICS following CSOM and BRS. The proportion of males that had ICS was higher in both CSOM and BRS patients. Optimal outcome is achieved in patients that presented with GCS of 13 and above.

  16. Endocrine consequences of an acute stress under different thermal conditions: A study of corticosterone, prolactin, and thyroid hormones in the pigeon (Columbia livia).

    In the context of global change, the physiological and hormonal stress responses have received much attention because of their implications in terms of allostasis. However, most studies have focused on glucocorticoids only as the "common" response to stressors while neglecting other endocrine axes and hormones (e.g. prolactin, thyroid hormones) that play a crucial role in metabolic adjustments. Interestingly, the responsiveness of all these endocrine axes to stress may depend on the energetic context and this context-dependent stress response has been overlooked so far. In the wild, temperature can vary to a large extent within a short time window and ambient temperature may affect these metabolic-related endocrine axes, and potentially, their responsiveness to an acute stressor. Here, we explicitly tested this hypothesis by examining the effect of a standardized stress protocol on multiple hormonal responses in the rock pigeon (Columbia livia). We tested the effect of an acute restraint stress on (1) corticosterone levels, (2) prolactin levels, and (3) thyroid hormone levels (triiodothyronine, thyroxine) in pigeons that were held either at cool temperature (experimental birds) or at room temperature (control birds) during the stress protocol. Although we found a significant influence of restraint stress on most hormone levels (corticosterone, prolactin, and thyroxine), triiodothyronine levels were not affected by the restraint stress. This demonstrates that stressors can have significant impact on multiple endocrine mechanisms. Importantly, all of these hormonal responses to stress were not affected by temperature, demonstrating that the exposure to cold temperature does not affect the way these hormone levels change in response to handling stress. This suggests that some endocrine responses to temperature decreases may be overridden by the endocrine responses to an acute restraint stress. Copyright © 2016 Elsevier Inc. All rights reserved.

    Otitis media (OM) is an inflammation of the middle ear associated with infection. Despite appropriate therapy, acute OM (AOM) can progress to chronic suppurative OM (CSOM) associated with ear drum perforation and purulent discharge. The effusion prevents the middle ear ossicles from properly relaying sound vibrations from the ear drum to the oval window of the inner ear, causing conductive hearing loss. In addition, the inflammatory mediators generated during CSOM can penetrate into the inner ear through the round window. This can cause the loss of hair cells in the cochlea, leading to sensorineural hearing loss. Pseudomonas aeruginosa and Staphylococcus aureus are the most predominant pathogens that cause CSOM. Although the pathogenesis of AOM is well studied, very limited research is available in relation to CSOM. With the emergence of antibiotic resistance as well as the ototoxicity of antibiotics and the potential risks of surgery, there is an urgent need to develop effective therapeutic strategies against CSOM. This warrants understanding the role of host immunity in CSOM and how the bacteria evade these potent immune responses. Understanding the molecular mechanisms leading to CSOM will help in designing novel treatment modalities against the disease and hence preventing the hearing loss. PMID:26248613

    Extrdural granulation or abscess is a possible complication of chronic suppurative otitis media (CSOM) with cholesteatoma. However, due to development of newer antibiotics and advances in bacteriology and imaging techniques, the incidence of extradural granulation or abscess has significantly decreased. The present study analyzed the clinical presentation, imaging findings, and surgical treatment of eight patients with CSOM with cholesteatoma extending to the cranial fossa. From 2000 to 2012, 1,010 patients were surgically treated for CSOM with cholesteatoma. Patients with extension to the cranial fossa were studied. Clinical presentation, imaging studies, operative findings, surgical treatment, and postoperative results were evaluated. Twenty cases (1.9%) in a series of 1,010 patients with CSOM with cholesteatoma had bony destruction of the cranial fossa in the temporal bone computed tomography (cr). Of the 20 cases, eight (0.79%) were identified as extradural granulation by magnetic resonance imaging. One patient exhibited nodular enhancement, but it disappeared on preoperative antibiotic treatment. Surgical access for removal of cholesteatoma with extradural granulation was accomplished through canal wall-down tympanomastoidectomy. CSOM with cholesteatoma can extend to either the middle or posterior cranial fossa. While CT is sufficient to reveal bony destruction of the cranial fossa, magnetic resonance imaging is required to differentiate and define intracranial extension of CSOM with cholesteatoma.

    To investigate the associations between patient age, sociological factors, and the microbiology of pediatric neck infections. Retrospective chart review of children up to 5 years old who underwent surgical management of suppurative cervical lymphadenitis. A total of 76 individuals met inclusion criteria; 93% of culture-positive infections were caused by Staphylococcus aureus in infants, compared with 59% in children between 13 months and 5 years of age (P = .002). Of the S aureus isolates, 51% were methicillin-resistant S aureus (MRSA) and 49% were methicillin-sensitive S aureus. Methicillin resistance was associated with African American race (P = .004); 67% of participants received empirical antibiotics prior to admission. Of these, 73% received antibiotics in the β-lactam class, and 25% received treatment with clindamycin. Incidence of MRSA is high in infants with cervical lymphadenitis who fail empirical antibiotic therapy and require surgical management. Empirical coverage for cervical lymphadenitis with β-lactam antibiotics may provide inadequate coverage for early infection in this population. © The Author(s) 2015.

    The thyroid glands are a vulnerable organ to ionizing radiation. Indeed the epidemiological studies have revealed an increase in the incidences of thyroid cancer among atomic bomb survivors in Hiroshima and Nagasaki and radiation casualties in Chernobyl. The carcinogenic risk for the thyroids is dependent on radiation dose, and higher in younger people. Recent advances in molecular biology contribute to clarify the mechanisms for thyroid carcinogenesis at genetic and molecular levels. Here radiation-induced thyroid carcinogenesis is reviewed from epidemiological data to basic research.

    The aim of this study was to assess the relationship of thyroid hormone levels with glomerular and tubular renal function in ARF. In thirty one patients with different underlying diseases, glomerular filtration (GFR) was estimated by measuring 99mTc-DTPA clearance and tubular function by 131I-OIH clearance. The thyroid status was evaluated by radioimmunoassays of T4, FT4, T3, FT3, rT3 and TSH, while the cortisol level was used to indicate the stress role. All the measurements were performed within 7 days as well after 1,3,6 and 12 months from the ARF onset. The results obtained were compared with those of 30 healthy subjects. At the ARF beginning, the impairment of renal function was manifested by the fall of 99mTc-DTPA clearance to 21∫7ml/min and 131I-OIH clearance to 172±34ml/min, while end values were 77±19ml/min and 395±70ml/min, respectively. The hormone analysis within 7 days, showed T3 decrease to 1.21±0.16nmol/l and the increase rT3 to 38±7ng/1ooml, as well as cortisol to 350±71ng/ml, but at the end of the study these hormone levels were normalized. Other hormone levels didn't differ significantly from control values. Regression analysis established significant correlation of 99mTc-DTPA clearance with T3 (r=0.693, p 100, OIH>500), partial recovery (DTPA 51-100, OIH 250-500) and without any recovery (DTPA<50,OIH<250), showed hormone disturbances proportional to the degree of renal function damage. The most severe disorders were found in the third group, where both total and free T4 and T3 were lowered, while rT3 and cortisol elevated at 7th day from ARF onset. After 12 months all these values associated with that of TSH were observed as declined.This study suggests thyroid hormone levels to be dependent on the renal function in ARF. Greater impairment of glomerular related to tubular function appears to be more responsible for thyroid dysfunction, due to uremic toxins retention as well as stress induced by the extreme function failure

    Purpose of review To summarize the mechanisms of iodine-induced hypothyroidism and hyperthyroidism, identify the risk factors for thyroid dysfunction following an iodine load, and summarize the major sources of excess iodine exposure. Recent findings Excess iodine is generally well tolerated, but individuals with underlying thyroid disease or other risk factors may be susceptible to iodine-induced thyroid dysfunction following acute or chronic exposure. Sources of increased iodine exposure include the global public health efforts of iodine supplementation, the escalating use of iodinated contrast radiologic studies, amiodarone administration in vulnerable patients, excess seaweed consumption, and various miscellaneous sources. Summary Iodine-induced thyroid dysfunction may be subclinical or overt. Recognition of the association between iodine excess and iodine-induced hypothyroidism or hyperthyroidism is important in the differential diagnosis of patients who present without a known cause of thyroid dysfunction.

    To assess the frequency of bacterial agents in chronic suppurative otitis media and the antibiotic susceptibility patterns of isolates among patients. A total of 185 patients clinically diagnosed with chronic suppurative otitis media were interviewed and middle-ear effusion samples were collected using sterile swabs. All bacterial isolates were identified by conventional microbiological methods. Antibiotic susceptibility patterns of the isolates were determined by Kirby-Bauer disc diffusion. Staphylococci spp. (64.9 per cent) were the most prevalent bacteria isolated, followed by Klebsiella spp. (12.9 per cent) and Pseudomonas aeruginosa (10.3 per cent). The most effective antibiotic for treatment of bacterial chronic suppurative otitis media was ciprofloxacin. Statistical analysis showed no significant difference in bacterial infestations among chronic suppurative otitis media patients and the antimicrobial susceptibility patterns of the bacterial isolates based on gender and age (p > 0.05). Our findings highlight the importance of a continuous and periodic evaluation of the bacteriological profile and antibiotic susceptibility patterns in chronic suppurative otitis media patients for efficacious treatment of the infection.

    The metabolic support of the critically ill patient is a relatively new target of active research and little is as yet known about the effects of critical illness on metabolism. The nonthyroidal illness syndrome, also known as the low T3 syndrome or euthyroid sick syndrome, describes a condition characterized by abnormal thyroid function tests encountered in patients with acute or chronic systemic illnesses. The laboratory parameters of this syndrome include low serum levels of triiodothyronine (T3) and high levels of reverse T3, with normal or low levels of thyroxine (T4) and normal or low levels of thyroid-stimulating hormone (TSH). This condition may affect 60 to 70% of critically ill patients. The changes in serum thyroid hormone levels in the critically ill patient seem to result from alterations in the peripheral metabolism of the thyroid hormones, in TSH regulation, in the binding of thyroid hormone to transport-protein and in receptor binding and intracellular uptake. Medications also have a very important role in these alterations. Hormonal changes can be seen within the first hours of critical illness and, interestingly, these changes correlate with final outcome. Data on the beneficial effect of thyroid hormone treatment on outcome in critically ill patients are so far controversial. Thyroid function generally returns to normal as the acute illness resolves.

  19. Intracanalicular antibiotics may obviate the need for surgical management of chronic suppurative canaliculitis

    Full Text Available Chronic suppurative lacrimal canaliculitis is an important cause of ocular surface discomfort. Treatment with topical antibiotics is often inadequate and surgical treatment by canaliculotomy and canalicular curettage has been the mainstay of treatment in the past. The role of canalicular antibiotic irrigation has been inadequately studied. We report the clinical features, microbiological profile and treatment outcome in a series of 12 patients with suppurative lacrimal canaliculitis. Two patients had Actinomyces infection, five had Nocardia infection and seven patients had polymicrobial infection. Three patients had resolution of canaliculitis on combination broad-spectrum topical antibiotic therapy using ciprofloxacin and fortified cefazolin. In nine patients, topical antibiotic therapy was combined with canalicular irrigation using fortified cefazolin. All patients had excellent resolution of canaliculitis without the need for surgical treatment. Availability of broad-spectrum antibiotics and canalicular irrigation may offer an alternative to surgery in the management of suppurative lacrimal canaliculitis.

    This chapter reviews the correlation between thyroid disease, other than cancer, and radiation in the literature. Radiation-induced thyroid disturbance is discussed in the context of external and internal irradiation. External irradiation of 10 to 40 Gy may lower thyroid function several months or years later. Oral administration of I-131 is widely given to patients with Basedow's disease; it may also lower thyroid function with increasing radiation doses. When giving 70 Gy or more of I-131, hypothyroidism has been reported to occur in 20-30% and at least 10%. Thyroiditis induced with internal I-131 irradiation has also been reported, but no data is available concerning external irradiation-induced thyroiditis. The incidence of nodular goiter was found to be several ten times higher with external irradiation than internal irradiation. Thyroid disturbance is correlated with A-bomb survivors. A-bomb radiation can be divided into early radiation within one minute after A-bombing and the subsequent residual radiation. Nodular goiter was significantly more frequent in the exposed group than the non-exposed group; it increased with increasing radiation doses and younger age (20 years or less) at the time of exposure. The incidence of decrease in thyroid function was higher with increasing radiation doses. However, in the case of Nagasaki, the incidence of hypothyroidism was significantly higher in the low-dose exposed group, especially A-bomb survivors aged 10-39 at the time of exposure and women.

    Full Text Available Chronic suppurative otitis media is among the most frequent illnesses treated in ENT wards. To establish the diagnosis, otomicroscopy alone usually suffice. Assessing the sense of hearing, often the sense of balance, too, is mandatory. Assessment of hearing will show the extent of conductive and sensorineural hearing loss. Apart from this, sometimes, when the finding is not obvious, it is necessary to conduct audiological investigation in more detail in order to establish whether the diagnosis of chronic suppurative otitis media is correct. Existence and extent of conductive hearing loss or confIrmation of tympanic membrane perforation by tympanometry can help a great deal. Also, some new results about the site of perforation and the middle ear volume influence on conductive hearing loss may help have a better insight into chronic suppurative otitis media. Assessing the sense of balance may show dysfunctions with not yet necessarily permanent damage: perilymphatic fistula and benign paroxysmal positional vertigo (BPPV. Unilateral or bilateral damage may be diagnosed with appropriate tests of vestibuloocular reflex (VOR: spontaneous nystagmus, head impulse test, head shaking test. These bedside tests do not require bulky, expensive equipment for stimulus delivery or special equipment for recording nystagmus. In addition, their significance is their ability to provide enough information without performing caloric testing which is contraindicated in chronic suppurative otitis media.

    Risk coefficients for thyroid disorders have been developed for both 131 I and external x or gamma low-LET radiation. A linear, no-threshold model has been used for thyroid neoplasms. A linear, threshold model has been used for other thyroid disorders. Improvements since the Reactor Safety Study were made possible by relevant new animal and human data. Major changes are as follows. Animal data are used to supplement the human experience where necessary. A specific risk estimate model is used for thyroid neoplasms, which accounts for observed effects of gender and age at exposure on risk. For thyroid cancer, the basis of the risk coefficients is the experience of North Americans following x-irradiation for benign disease in childhood. This recognizes possible differences in susceptibility in people of different heritage. A minimum induction period for thyroid neoplasms following irradiation is used to define periods at risk. An upper bound risk coefficient for cancer induction following exposure to 131 I is based on human experience at relatively low dose exposures. While the overall lifetime risks of death due to thyroid cancer are consistent with projections by the ICRP, BEIR III, and UNSCEAR Reports, the current model permits greater flexibility in determining risk for population subgroups. 88 references, 8 tables

    The problem of thyroid disorder is extensive in Bangladesh, even more than that of other developing countries. The high incidence rate of goiter is reduced after universal iodine supplement. This study has been undertaken to study the an-thyroid anti-body level among the thyroid disorder population (anti-TPO and anti-thyrogobulin antibody) and TSAb among Graves' disease and sub-acute thyroiditis. This study was performed over 300 persons of them 150 have some type of thyroid (patient) disorder and 150 have got no clinical thyroid disorder (volunteer). We also studied TSH receptor anti-body (TSAb) in 112 Graves' disease patients and 86 patients with sub-acute thyroiditis. All the patient had I-131 Uptake in 24 hours. Among the patient 42(28%) had elevated anti-TPO, 12(8%) had borderline and 96(64%) had normal anti-TPO. It was found the uptake percentage of this group of patient hade slight lower than average uptake of our population. 13±5% It was found that 28(18.6%) had elevated anti thyrogobulin anti-body, 9 (6.2%) had borderline and 113(75.3%) had normal level anti thyrogobulin anti-body. It was also that found the uptake percentage of this group of patient had slight lower than average uptake of our population. We also found that 21% patient had elevated both the antibodies. Among the normal volunteer 24(16%) had elevated anti-TPO, 8 (5.3%) had borderline and 118(78.7%) had normal level of anti-TPO. Thyroid 1-131 uptake was 15±4%. It was found that 14(9.3%) had elevated anti thyrogobulin anti-body, 6(4.1%) had borderline and 130 (76.6%) had normal level of anti thyrogobulin anti-body. Among the normal volunteer 6% had elevated both the antibodies. It was found 91% patient Graves' disease had positive TSAb and 92% of' sub-acute thyroiditis has negative TSAb, I-131 uptake was 31±8% among this group of patient.. Thyroid stimulating antibody is found in 91% of Graves' disease and very few patient with sub-acute thyroiditis. The uptake of I-131 in sub-acute

    Toll-like receptors (TLRs) have a prominent role in inducing innate immune response. It has been suggested that regulation of TLRs is involved in the pathogenesis of chronic otitis media. TLR 2 and TLR 4 polymorphisms were connected with susceptibility to acute otitis and chronic otitis with effusion. The objective of this study was to establish expression of TLR 2 and 4 on middle ear mucosa in different types of chronic suppurative otitis media (CSOM), and the influence of gene polymorphisms TLR 2 Arg753Gln and TLR 4 Thr399Ile and Asp299Gly to susceptibility to CSOM. Middle ear mucosa and full blood samples were obtained from 85 patients with chronic suppurative otitis media with and without cholesteatoma. Control group for mucosal TLR expression consisted of 71 samples of middle ear mucosa taken from patients with otosclerosis, and control group for DNA polymorphism consisted of 100 full blood samples in healthy subjects. DNA polymorphism detection was done with restriction fragment length polymorphism in RT PCR. Expression of TLR 2 and 4 was determined with immunohistochemical staining. TLR 2 and TLR 4 expression on the middle ear mucosa was not influenced by age of the patients with chronic otitis media. Incidence of TLR 2 Arg753Gln polymorphism was significantly higher in patients with chronic otitis media, compared to control group. Significant association between TLR 2 Arg753Gln polymorphism and different types of mucosal changes in patients with chronic otitis media was established. TLR 2 and 4 expression on experimental group mucosa was significantly different compared to control group, where there was no expression (p=0.000). Strong dependence of TLR 2 and TLR 4 expression on middle ear mucosa with different mucosal changes and immunohistochemical activity after staining was detected. Certain polymorphisms in TLR genes could be indicative for susceptibility to chronic otitis media. Expression of TLR 2 and 4 on middle ear mucosa was more dependable on

    The purpose of this review was to systematically appraise the world literature to identify existing patient-reported outcome measures (PROMs) for the assessment of outcomes in patients with chronic suppurative otitis media, to verify the diversity of the individual questionnaire items, to report the methods employed to evaluate the questionnaires, and to identify areas for development in the future. Embase (January 1980-November 2014), MEDLINE (January 1946-November 2014), Cumulative Index to Nursing and Allied Health Literature (January 1981-November 2014), and PsycINFO (January 1806-November 2014). A systematic literature search was independently undertaken by the two authors according to predefined inclusion and exclusion criteria. Nine original articles were identified, which overall outlined the evaluation of four different questionnaires. This systematic appraisal of the world literature has identified four PROM questionnaires for use in patients with chronic suppurative otitis media. All four questionnaires evaluate reliability and validity using different psychometric methods. The Chronic Ear Survey questionnaire has been most broadly evaluated and disseminated. All four questionnaires assess static health status. There are many advantages to developing a dynamic one-hit questionnaire to assess the health status of patients having undergone an intervention for chronic suppurative otitis media.

    Association between autoimmune thyroiditis (CLT) and thyroid cancer remains not clear. Although both diseases often occur simultaneously in histological samples, it is not yet clear whether CLT can be regarded as a risk factor for thyroid malignancy. This review focus on the known epidemiological and molecular genetics links between both diseases. Most studies have shown a significant association between thyroid cancer and positive antibodies to thyroglobulin and histological evidence of CLT, as well. Both disorders share some risk factors (greater incidence in women, in areas with adequate supply of iodine and in patients after radiotherapy of the neck) and molecular genetics linkage. For example: RET/PTC rearrangements could be more often found in carcinomas associated with CLT, but this mutation could be found in benign lesions such as CLT, as well. CLT seems to be a positive prognostic factor in patients with differentiated thyroid cancer. It is associated with less invasive forms of tumor, lower occurrence of infiltrated lymphatic nodes and a lower risk of recurrence.

    An imported crossbred Angus beef steer aged eight to twelve months died suddenly on the eighth day of a quarantine period in Japan. Gross examination showed the peritoneum and mesentery consisted of numerous nodules of various sizes. Histological examination revealed chronic suppurative granulomatous peritonitis with eosinophilic rosettes surrounding colonies of Gram-negative bacilli. The bacteria isolated from the nodules were confirmed to be Actinobacillus lignieresii based on the results of 16S rRNA gene sequencing and immunohistochemistry. Antibiotic sensitivity testing showed that the isolate was resistant to penicillin. Thus, a diagnosis of atypical actinobacillosis caused by A. lignieresii was made.

    Clinical and radiologic examinations of 17 patients with rectal and colonic perforation with further spread of suppurative process in the retroperitoneal space and beyond the pelvis has been carried out. Surgical and pathological comparisons show that the fistulas go along the fascial-muscular sheaths and vessels. Large intestinal fistulas are divided by their character into simple complete and incomplete and complex complete and incomplete. Use of irrigoscopy is advisable along with fistulography for proper diagnosis. In such cases radiologic examination plays a decisive role in the diagnosis revision, development of the therapeutic approach, and the confirmation of the process intensity.

    Full Text Available Abstract Background Lithium is an integral drug used in the management of acute mania, unipolar and bipolar depression and prophylaxis of bipolar disorders. Thyroid abnormalities associated with treatment with lithium have been widely reported in medical literature to date. These include goitre, hypothyroidism, hyperthyroidism and autoimmune thyroiditis. This current review explores the varied thyroid abnormalities frequently encountered among patients on lithium therapy and their management, since lithium is still a fundamental and widely drug used in psychiatry and Internal Medicine. Methods PubMed database and Google scholar were used to search for relevant English language articles relating to lithium therapy and thyroid abnormalities up to December 2012. The search terms used were lithium treatment, thyroid abnormalities, thyroid dysfunction, goitre, hypothyroidism, hyperthyroidism, thyrotoxicosis, autoimmune thyroiditis, lithium toxicity, treatment of affective disorders and depression and side effects of antipsychotic drugs. Reference lists of the identified articles were further used to identify other studies. Results Lithium affects normal thyroid functioning through multiple mechanisms. At the cellular level, it decreases thyroid hormone synthesis and release. It also decreases peripheral deiodination of tetraiodothyronine (T4 or thyroxine by decreasing the activity of type I 5’ de-iodinase enzyme. Hypothyroidism and goitre (clinically and/ultrasonographically detected are the most prevalent thyroid abnormalities among patients on long term lithium therapy. Lithium induced hyperthyroidism is very infrequent. Lithium increases the propensity to thyroid autoimmunity in susceptible individuals due to its effect of augmenting the activity of B lymphocytes and reducing the ratio of circulating suppressor to cytotoxic T cells. Conclusions Thyroid function tests (serum thyroid stimulating hormone, free thyroid hormones-T4 and

    Non-suppurative encephalitis is one of the most frequent pathological diagnosis in cattle with neurological disease, but there is a gap in the knowledge on disease-associated pathogens. In order to identify viruses that are associated with non-suppurative encephalitis in cattle, we used a viral metagenomics approach on a sample set of 16 neurologically-diseased cows. We detected six virus candidates: parainfluenza virus 5 (PIV-5), bovine astrovirus CH13/NeuroS1 (BoAstV-CH13/NeuroS1), bovine polyomavirus 2 (BPyV-2 SF), ovine herpesvirus 2 (OvHV-2), bovine herpesvirus 6 (BHV-6) and a novel bovine betaretrovirus termed BoRV-CH15. In a case-control study using PCR, BoAstV-CH13 (p=0.046), BoPV-2 SF (p=0.005) and BoHV-6 (p=4.3E-05) were statistically associated with the disease. These data expand our knowledge on encephalitis-associated pathogens in cattle and point to the value of NGS in resolving complex infection scenarios in a clinical disease setting.

    Differentiated thyroid carcinoma was studied with regard to mode of presentation, initial findings, treatment and survival. The classic signs, symptoms, physical and scan findings were found to be present in approximately 70% of the patients. Prognosis was found to be dependent on age of presentation more than any other factor. Patients with prior exposure to radiation were found to have more extensive disease and require more extensive surgery but ultimately had the same prognosis for 15-year cure. Treatment for distant metastatic disease by surgery, radioactive iodine and external radiation all resulted in long-term survival in certain cases

  4. Thyroiditis: an integrated approach.

    Thyroiditis is a general term that encompasses several clinical disorders characterized by inflammation of the thyroid gland. The most common is Hashimoto thyroiditis; patients typically present with a nontender goiter, hypothyroidism, and an elevated thyroid peroxidase antibody level. Treatment with levothyroxine ameliorates the hypothyroidism and may reduce goiter size. Postpartum thyroiditis is transient or persistent thyroid dysfunction that occurs within one year of childbirth, miscarriage, or medical abortion. Release of preformed thyroid hormone into the bloodstream may result in hyperthyroidism. This may be followed by transient or permanent hypothyroidism as a result of depletion of thyroid hormone stores and destruction of thyroid hormone-producing cells. Patients should be monitored for changes in thyroid function. Beta blockers can treat symptoms in the initial hyperthyroid phase; in the subsequent hypothyroid phase, levothyroxine should be considered in women with a serum thyroid-stimulating hormone level greater than 10 mIU per L, or in women with a thyroid-stimulating hormone level of 4 to 10 mIU per L who are symptomatic or desire fertility. Subacute thyroiditis is a transient thyrotoxic state characterized by anterior neck pain, suppressed thyroid-stimulating hormone, and low radioactive iodine uptake on thyroid scanning. Many cases of subacute thyroiditis follow an upper respiratory viral illness, which is thought to trigger an inflammatory destruction of thyroid follicles. In most cases, the thyroid gland spontaneously resumes normal thyroid hormone production after several months. Treatment with high-dose acetylsalicylic acid or nonsteroidal anti-inflammatory drugs is directed toward relief of thyroid pain.

    To provide quantitative data on the risk of thyroid cancer following 131 I exposure, 34104 patients administered 131 I for diagnostic purposes were followed for up to 40 years. Mean thyroid dose was estimated as 1.1 Gy, and 67 thyroid cancers occurred in contrast to 49.7 expected [standardized incidence ratio (SIR)=1.35; 95% confidence interval (CI) 1.05-1.71]. Excess cancers were apparent only among patients referred because of a suspected thyroid tumor and no increased risk was seen among those referred for other reasons. Further, risk was not related to radiation dose to the thyroid gland, time since exposure, or age at exposure. The slight excess of thyroid cancer, then appeared due to the underlying thyroid condition and not radiation exposure. Among those under age 20 years when 131 I was administered, a small excess risk (3 cancers vs 1.8 expected) was about 2-10 times lower than that predicted from A-bomb data. These data suggest that protraction of dose may result in a lower risk than acute x-ray exposure of the same total dose

    Full Text Available Abstract Introduction Hyperthyroidism is a well established cause of atrial fibrillation (AF. Thyroid Stimulating Hormone-secreting pituitary tumours are rare causes of pituitary hyperthyroidism. Whilst pituitary causes of hyperthyroidism are much less common than primary thyroid pathology, establishing a clear aetiology is critical in minimising complications and providing appropriate treatment. Measuring Thyroid Stimulating Hormone (TSH alone to screen for hyperthyroidism may be insufficient to appropriately evaluate the thyroid status in such cases. Case presentation A 63-year-old Caucasian man, previously fit and well, presented with a five-day history of shortness of breath associated with wheeze and dry cough. He denied symptoms of hyperthyroidism and his family, social and past history were unremarkable. Initial investigation was in keeping with a diagnosis of atrial fibrillation (AF with fast ventricular response leading to cardiac decompensation. TSH 6.2 (Normal Range = 0.40 – 4.00 mU/L, Free T3 of 12.5 (4.00 – 6.8 pmol/L and Free T4 51(10–30 pmol/L. Heterophilic antibodies were ruled out. Testosterone was elevated at 43.10 (Normal range: 10.00 – 31.00 nmol/L with an elevated FSH, 18.1 (1.0–7.0 U/L and elevated LH, 12.4 (1.0–8.0 U/L. Growth Hormone, IGF-1 and prolactin were normal. MRI showed a 2.4 cm pituitary macroadenoma. Visual field tests showed a right inferotemporal defect. While awaiting neurosurgical removal of the tumour, the patient was commenced on antithyroid medication (carbimazole and maintained on this until successful trans-sphenoidal excision of the macroadenoma had been performed. AF persisted post-operatively, but was electrically cardioverted subsequently and he remains in sinus rhythm at twelve months follow-up off all treatment. Conclusion This case reiterates the need to evaluate thyroid function in all patients presenting with atrial fibrillation. TSH-secreting pituitary adenomas must be considered

    Full Text Available BACKGROUND The aim of the study is to study the- 1. Correlation between sonological and histopathological diagnosis of acute appendicitis. 2. Prevalence of acute appendicitis in various age groups. MATERIALS AND METHODS The study was conducted in the Department of Radiodiagnosis, MVJ Medical College and Research Hospital, Bangalore, for a period of 2 years from March 2013 to February 2015. Data collection was prospective. A computer-assisted search of all the reports of ultrasonography with the diagnosis of acute appendicitis was conducted within the departmental database. A total of 244 patients (128 male patients and 116 female patients with acute appendicitis were identified and the study was conducted. RESULTS In the study, total of 244 patients were diagnosed with acute appendicitis. Out of these, 128 patients were males and 116 patients were females. The incidence of acute appendicitis was most prevalent in age group between 21 to 30 years (36.5% in our study. The least incidence was noted in age group of above 60 yrs. with only 1 out of 244 patients (0.4% was diagnosed with acute appendicitis. The histological features noted were suppuration/inflammation, gangrenous, lymphoid hyperplasia and perforation. In our study, 143 inflammation/suppuration (58.6%, 37 gangrenous (15.1%, 24 lymphoid hyperplastic (9.8% and 1 perforation (0.4% was noted. Hence, the incidence of inflammation/suppuration was found to be most common and perforation was found to be the least finding. The suppurative/inflammatory feature was most common histological type in all the age groups except for the age group above 60 yrs. The gangrenous features were most commonly seen in the age group between 11 to 20 yrs. followed by 20 to 30 yrs. Faecolith was most commonly found in age group of 21 to 30 yrs. (12 cases followed by age group of 11 to 20 yrs. (10 cases. CONCLUSION It was noted that the incidence of acute appendicitis was most commonly noted in younger age group

  12. MOUTH FLOOR DIFFUSE SUPPURATION COMPLICATED BY CERVICOTHORACIC NECROTIZING FASCIITIS – A CASE REPORT

    Directory of Open Access Journals (Sweden)

    Violeta TRANDAFIR

    2013-03-01

    Full Text Available Necrotizing fasciitis is a severe soft tissue infection, often life-threatening, characterized by necrosis of the subcutaneous and fascial tissue, which can be extended along the fascial plans, affecting the adjacent vessels, nerves and muscle tissue. The predisposing factors of the disease include: advanced age, immuno-compromised bodies, diabetes, chronic alcoholism and chronic smoking. Necrotizing fasciitis in head and neck segments is rare, usually with an odontogenic source of infection. In the early stages of evolution, a necrotizing fasciitis is difficult to differentiate from the non-necrotizing infection of the soft tissue. Due to its extremely severe evolution, an early presumptive diagnosis is necessary (based on clinical and imaging aspects, as well as a prompt aggressive surgery backed by an intensive care support. The clinical case of an immunocompromised patient admitted for a mouth floor diffuse suppuration, previously complicated with cervicothoracic necrotizing fasciitis with aggressive evolution, is discussed in the following.

    ᅟ: Helicobacter bilis is a commensal bacterium causing chronic hepatitis and colitis in mice. In humans, enterohepatic Helicobacter spp. are associated with chronic hepatobiliary diseases. We aimed at understanding the microbial etiology in a patient with X-linked agammaglobulinemia presenting with suppurative cholangitis. 16S rDNA PCR directly performed on a liver biopsy retrieved DNA of H. bilis. Clinical outcome resulted in the normalization of clinical and biological parameters under antibiotic treatment by a combination of ceftriaxone, metronidazole, and doxycyclin followed by a 2-week treatment with moxifloxacin and a 2-month treatment with azithromycin. In conclusion, these data suggest a specific clinical and microbiological approach in patients with humoral deficiency in order to detect H. bilis hepatobiliary diseases.

    BACKGROUND:: Children in the developing parts of the world have a high prevalence of chronic suppurative otitis media (CSOM). It is estimated that 65 to 330 million people worldwide have CSOM, yet very little is known about the natural course of the disease. The Inuit population of the Arctic......-based cohort of 591 children originally examined during 1993 to 1994 at 3 to 8 years of age. Follow-up was attempted among 348 individuals still living in the areas. Video otoscopy and tympanometry were used. Data on otologic disease, ear surgery, and antibiotic use for otitis media were collected from medical...... of spontaneous healing was not influenced by the age at which CSOM was diagnosed in the initial study. Thirty-nine individuals (17%) had CSOM in either the initial study or at follow-up. Of these, 2 had never received antibiotic treatment for otitis media, and 15 had been treated less than 3 times.

    2017-01-01

    Lugol's solution is usually employed for a limited period for thyroidectomy preparation in patients with Graves' disease and for the control of severe thyrotoxicosis and thyroid storm. We describe a rare case of Lugol's solution-induced painless thyroiditis. In November 2014, a 59-year-old woman was prescribed Lugol's solution four drops per day for the alleviation of menopausal symptoms. She was referred to our clinic in June 2015 for fatigue, hair loss, and a 20-lb weight loss without thyroid pain or discomfort. Physical examination revealed a normal thyroid gland. On 7 May 2015, laboratory tests revealed a suppressed thyroid-stimulating hormone (TSH) 0.01 U/L with elevated free T4 3.31 ng/dL (42.54 pmol/L). Repeat testing on 25 May 2015 showed spontaneous normalization of the free thyroid hormone levels with persistently low TSH 0.10 U/L. Following these results, a family physician prescribed methimazole 10 mg PO TID and very soon after, the TSH concentration rose to >100 U/L along with subnormal free T4 and T3 levels. Methimazole was promptly discontinued, namely within 18 days of its initiation. Over the course of the next few months, the patient spontaneously achieved clinical and biochemical euthyroidism. To our knowledge, this is a unique case of painless thyroiditis induced by Lugol's solution, which has not been reported before. Lugol's solution is a short-term medication given for the preparation of thyroidectomy in patients with Graves' disease and for the control of severe thyrotoxicosis. Iodine excess can cause both hyperthyroidism and hypothyroidism. Rarely, Lugol's solution can cause acute painless thyroiditis. Lugol's solution is used for thyroidectomy preparation in patients with Graves' disease and for the control of severe thyrotoxicosis and thyroid storm.Iodine excess can cause both hypothyroidism and thyrotoxicosis. Thyroid glands with an underlying pathology are particularly susceptible to the adverse effect of iodine

    Aim. To investigate obstetric features of pregnant women with thyroid disorders and thyroid function tests of their newborn infants. Methods. Women with hypothyroidism and having anti-thyroglobulin (ATG) and anti-thyroid peroxidase (anti-TPO) antibodies were assigned as group I, women with hypothyroidism who did not have autoantibodies were assigned as group II, and women without thyroid problems were assigned as group III. Results. Pregnant women with autoimmune hypothyroidism (group I) had more preterm delivery and their babies needed more frequent neonatal intensive care unit (NICU) admission. In group I, one infant was diagnosed with compensated hypothyroidism and one infant had transient hyperthyrotropinemia. Five infants (23.8%) in group II had thyroid-stimulating hormone (TSH) levels >20 mIU/mL. Only two of them had TSH level >7 mIU/L at the 3rd postnatal week, and all had normal free T4 (FT4). Median maternal TSH level of these five infants with TSH >20 mIU/mL was 6.6 mIU/mL. In group III, six infants (6.5%) had TSH levels above >20 mIU/mL at the 1st postnatal week. Conclusion. Infants of mothers with thyroid problems are more likely to have elevated TSH and higher recall rate on neonatal thyroid screening. Women with thyroid disorders and their newborn infants should be followed closely for both obstetrical problems and for thyroid dysfunction. PMID:23737782

    Full Text Available Most of the studies have shown a higher risk for subclinical and clinical hypothyroidism, antithyroid autoantibodies [overall antithyroid peroxidase antibodies (TPOAb], and in general, thyroid autoimmunity, overall in the female gender in patients with sarcoidosis (S. A significantly higher prevalence of clinical hypothyroidism and Graves’ disease was also described in female S patients with respect to controls. Gallium-67 (Ga-67 scyntigraphy in S patients, in the case of thyroid uptake, suggests the presence of aggressive autoimmune thyroiditis and hypothyroidism. For this reason, ultrasonography and thyroid function should be done in the case of Ga-67 thyroid uptake. In conclusion, thyroid function, TPOAb measurement, and ultrasonography should be done to assess the clinical profile in female S patients, and the ones at high risk (female individuals, with TPOAb positivity, and hypoechoic and small thyroid should have periodically thyroid function evaluations and suitable treatments.

  12. Thyroid and menopause.

    2014-06-01

    Thyroid dysfunction is common in the general population especially in women. All thyroid diseases are in fact more common in women than in men and may interfere with the reproductive system. Thyroid function and the gonadal axes are related throughout the woman's fertile period. The relationship between the two glands is mutual. In particular, thyroid hormones affect the reproductive function both directly and indirectly through several actions. Studies on the relationship between menopause and thyroid function are few and do not allow to clarify whether menopause has an effect on the thyroid regardless of aging. With aging, the main changes regarding thyroid physiology and function are: a reduction of thyroid iodine uptake, free thyroxine and free triiodothyronine synthesis and catabolism of free thyroxine while reverse triiodothyronine increases; the level of thyroid stimulating hormone remains normal with sometimes a tendency to higher limits. These changes are present in both sexes without distinction between males and females. The complexity of the relationships can be summarized in three aspects: thyroid status does not influence significantly the climacteric syndrome; menopause may modify the clinical expression of some thyroid diseases, particularly the autoimmune ones; thyroid function is not directly involved in the pathogenesis of the complications of menopause. However, coronary atherosclerosis and osteoporosis may be aggravated in the presence of hyperthyroidism or hypothyroidism. The effects of postmenopausal estrogen replacement on thyroxine requirements in women with hypothyroidism should be considered.

    Full text of the publication follows: The thyroid gland in children is among the most sensitive organs to the carcinogenic effects of ionizing radiation, and very young children are at especially high risk. Due to extreme sensitivity of the thyroid gland in children, there is a risk of radiation - induced thyroid cancer even when the thyroid gland is outside the irradiated field. Increased incidence of thyroid cancer has been noted following radiotherapy not only for childhood Hodgkin disease (majority of observed patients), but also for non-Hodgkin lymphoma, neuroblastoma, Wilms tumor, acute lymphocytic leukemia and tumors of the central nervous system also. Radiation-induced tumors begin to appear 5-10 years after irradiation and excess risk persists for decades, perhaps for the remainder of life. The incidence of thyroid cancer is two- to threefold higher among females than males. Most of the thyroid cancers that occur in association with irradiation are of the papillary type, for which the cure rate is high if tumors are detected early. Our Department in co-operation with Department of Children Hematology and Oncology Charles University Second Faculty of Medicine and Faculty Hospital Motol monitors patients after therapy for cancer in childhood for the long term period. The monitoring is focused on detection of thyroid disorders that occur as last consequences of oncology therapy, especially early detection of nodular changes in thyroid gland and thyroid carcinogenesis. The survey presents two patients observed in our department that were diagnosed with the papillary thyroid carcinoma which occurred 15 and more years after radiotherapy for childhood cancer. After total thyroidectomy they underwent therapy with radioiodine. After radiotherapy it is necessary to pursue a long-term following and assure interdisciplinary co-operation which enables early detection of last consequences of radiotherapy, especially the most serious ones as secondary carcinogenesis

    Bacterial infection of Salmonella enterica serotype Typhi is rare in the United States but endemic in many developing countries. Approximately 3-5% of patients become chronic asymptomatic carriers. We describe an atypical presentation of S. enterica serotype Typhi infection in a 10-year-old male, whose cholecystechtomy and bile culture revealed chronic carrier status despite negative stool tests and the absence of gallstones. The gallbladder showed marked thickening of the wall with an intense suppurative granulomatous reaction.

    Ectopy is the most common embryogenetic defect of the thyroid gland, representing between 48 and 61% of all thyroid dysgeneses. Persistence of thyroid tissue in the context of a thyroglossal duct remnant and lingual thyroid tissue are the most common defects. Although most cases of ectopic thyroid are asymptomatic, any disease affecting the thyroid may potentially involve the ectopic tissue, including malignancies. The prevalence of differentiated thyroid carcinoma in lingual thyroid and thyroglossal duct cyst is around 1% of patients affected with the above thyroid ectopies. We here review the current literature concerning primary thyroid carcinomas originating from thyroid tissue on thyroglossal duct cysts and lingual thyroid. Copyright © 2016 SEEN.

    In the context of a functional thyroid exploration study the physiopathology of the thyroid was reviewed on the basis of data supplied by the use of radioisotopes, especially radioiodine. It was pointed out in this respect that the functional activity of the thyroid is closely bound up with the iodine metabolism. The different stages of the iodine metabolism were therefore described in relation to the methods used for their exploration: study of iodine intake to the thyroid and uptake measurement; hormonogenesis and secretion of hormone iodine; transport and circulation of thyroid hormones; exploration of the hypothalamus-pituitary gland-thyroid axis. It was pointed out in addition that the morphological examination often complements the thyroid function exploration and is carried out whenever thyroid palpation reveals an anomaly. Data obtained by scintigraphy are given in this repect. Furthermore the remarkable capacity of hyperthyroid tissues to concentrate radioactive iodine may be used therapeutically to perform an endogenous irradiation of the thyroid. The treatment of both hyperthyroidism and thyroid cancers with radioactive iodine was studied [fr

    The present study aimed to investigate the potential involvement of specific T-cell subpopulations in granulation tissue formation in chronic suppurative otitis media (CSOM). Fifteen patients with CSOM were enrolled in this study. Granulation tissues were obtained from the middle ear cavity. Hematoxylin and eosin staining was performed for histopathological observation, and different T-cell subpopulations were characterized by immunohistochemistry. No evident association was identified between granulation tissue formation and disease course. The number of cluster of differentiation 8 + (CD8 + ) T cells, forkhead box P3 + (FOXP3 + ) regulatory T (Treg) cells and OX40 + T cells were significantly higher in granulation tissues from patients with ear discharge within the last 6 months compared to those without (Pgranulation tissues had more CD8 + T cells and FOXP3 + Treg cells compared to the mature granulation tissues (Pgranulation tissues in CSOM with different disease courses or with ear discharge, suggesting that T cell-mediated cellular immunity is involved in lesion formation of CSOM.

    Chronic suppurative otitis media (CSOM) is common among children in southern Africa. Managing associated co-morbidities may result in earlier disease resolution. Children 4 weeks were recruited to the study. Each child underwent a full clinical examination, a blood count, an HIV test and CD4 cell count, if found to be infected. The study included 86 children, and the median age was 4.6 years. HIV infection was present in 45 of 83 children (54.2%), of which 23 (51.1%) were receiving antiretroviral treatment at the time of presentation. Underweight was present in 22 of 85 (25.9%) children and in 17 of the 45 (37.8%) HIV-infected children. One or more clinical signs (not aural-related) were found in 46 of 86 (53.4%) children. Cholesteatoma was found in 23 of 113 (20.4%) ears, and 9 of 86 (10.5%) children had serious associated aural or intracranial complications. A high percentage of children with CSOM have associated pathology that needs to be diagnosed to optimally manage CSOM. © The Author [2014]. Published by Oxford University Press. All rights reserved.

    To investigate the impact of chronic suppurative lung disease (CSLD) on growth and lung function in the child as well as quality of life of the child and parent. Cross-sectional study in 60 children with CSLD, bronchiectasis (including cystic fibrosis) and bronchiolitis obliterans. Thirty-five parents were interviewed while the remaining patients' data were collated from medical notes. Anthropometric measurements at first diagnosis and at interview were compared. The most recent lung function was also collected. The Parent Cough-Specific Quality of Life (PC-QOL) and the Depression, Anxiety and Stress (DASS21) questionnaires were administered to parents. The median (range) age at diagnosis was 1.3 (0.2-11) years. The median (IQR) duration between anthropometric measurements was 35 (15, 59) months. Children with cystic fibrosis (CF) had improvements both in weight and BMI, whereas children with non-CF CSLD had no improvements in any growth parameter. Seventy-eight percent of children who performed spirometry had values parents had abnormal DASS21 scores with 54% being stressed and 51% being depressed. Mental health was better in parents of children with CF. CSLD had a negative impact on growth, lung function, and quality of life. Children with CF had a better outcome in growth as well as better parental mental health compared to children with other etiologies.

    The reported relationship of radiation exposure and thyroid carcinoma stimulated this retrospective study of 298 patients treated at St. Jude Children's Hospital with radiation therapy to the neck for childhood cancer to identify patients who developed subsequent thyroid abnormalities. This series includes 153 patients with Hodgkin's disease, 95 with acute lymphocytic leukemia, 28 with lymphoepithelioma, and 22 with miscellaneous tumors. Inclusion in the study required 5 years of disease-free survival following therapy for their original tumor, which included thyroid irradiation. Follow-up has been 100%. Most patients also received chemotherapy. Seventeen patients were found to have decreased thyroid reserve with normal levels of free triiodothyroxine (T3) or free thyroxin, (T4) and an elevated level of thyroid-stimulating hormone (TSH). In nine patients hypothyroidism developed, with decreased T3 or T4 levels and an elevated level of TSH. One hyperthyroid patient was identified. Two patients had thyroiditis, and seven had thyroid neoplasms: (carcinoma in two, adenoma in two, colloid nodule in one, and undiagnosed nodules in two). This survey has demonstrated an increased incidence of thyroid dysfunction and thyroid neoplasia when compared to the general population. The importance of long-term follow-up for thyroid disease is emphasized in patients who have received thyroid irradiation. The possible role of subclinical hypothyroidism with TSH elevation coupled with radiation damage to the thyroid gland as a model for the development of neoplastic disease is discussed

    We wanted to describe the characteristic ultrasonography (US) features and clinical findings for making the diagnosis of subacute granulomatous thyroiditis. A total of 31 lesions from 27 patients were confirmed as subacute granulomatous thyroiditis by US-guided fine needle aspiration biopsy. We analyzed the ultrasonographic findings such as the lesion's size, margin and shape, the discrepancy between length and breadth and the vascularity. The clinical findings such as acute neck pain or fever were reviewed. The follow-up clinical and ultrasonographic data were reviewed for 15 patients. The thyroid gland was found to be enlarged in five patients, it was normal size in 20 patients and it was smaller in two patients. All the lesions had focally ill-defined hypoechogenicity. Hypervascularity was not noted in any of the lesions. Painful neck swelling was present in 18 patients. An accompanying fever was documented in nine of the 18 patients. Twelve patients showed disappearance (n = 3) or a decreased size (n = 9) of their lesions on follow-up US. The presence of ill-defined hypoechoic thyroid lesions without a discrete round or oval shape is characteristic for subacute granulomatous thyroiditis, and particularly when this is associated with painful neck swelling and/or fever.

In these cases T3 level is usually decreased and this condition is called "low T3 syndrome" which is usually reversed by treating the under lying Disease. thyroid function test analysis before and after diabetic ketoacidosis treatment. In this cross sectional study thyroid function tests were analyzed in 16 diabetic ketoacidosis patients according to American diabetic association before and after insulin therapy. mean triiodothyronine (T3) level before and after ketoacidosis treatment were 63.2±28.2ng/dl/and 78.5±26.2ng/dl (P. value 0.00) respectively and the mean thyroxin level (T4) before and after ketoacidosis were 3.18±1.4ng/dl and 5.17±2.4ng/dl (P. value=0.00) .Mean thyrotropin (TSH) level and triiodothyronine uptake (T3RU) before and after treatment showed no significant difference. Diabetic ketoacidosis is a sever systemic disease which along with reduction in T3 level, T4 level is also decreased and TSH level is normal. The changes in Thyroid hormones are reversed to normal after treatment of ketoacidosis so it is recommended in interpreting results of TFT in these patients we should consider these facts and thyroid function test should be repeated after treatment.

    Context: Thyroid hormone production is dependent on adequate iodine intake. Excess iodine is generally well-tolerated, but thyroid dysfunction can occur in susceptible individuals after excess iodine exposure. Radiological iodinated contrast media represent an increasingly common source of excess iodine. Objective: This review will discuss the thyroidal response after acute exposure to excess iodine; contrast iodine-induced thyroid dysfunction; risks of iodine-induced thyroid dysfunction in vulnerable populations, such as the fetus, neonate, and patients with impaired renal function; and recommendations for the assessment and treatment of contrast iodine-induced thyroid dysfunction. Methods: Data for this review were identified by searching PubMed, Google Scholar, and references from relevant articles from 1948 to 2014. Conclusions: With the increase in the use of computed tomography scans in the United States, there is increasing risk of contrast-induced thyroid dysfunction. Patients at risk of developing iodine-induced thyroid dysfunction should be closely monitored after receiving iodinated contrast media and should be treated as needed. PMID:25375985

    Full Text Available Autoimmune thyroid diseases (ATDs are immune-endocrine disorders affecting the thyroid gland and, eventually, also a number of other systemic targets, including the brain and the nervous system. Encephalopathy associated with autoimmune thyroid disease (EAATD is a rare, heterogeneous condition arising from the background of an ATD. It is characterised by neurological and/or psychiatric symptoms with acute or sub-acute onset, and virtually any neurological or psychiatric symptom can appear. However, EAATD often presents with confusion, altered consciousness, seizures, or myoclonus. The majority of cases are associated with Hashimoto’s thyroiditis, but a number of patients with Graves’ disease have also been described. EAATD is likely an immune-mediated disorder. Its exact prevalence has not been precisely elucidated, with an increasing number of cases reported in the last few years. Most EAATD patients respond in a dramatic manner to corticosteroids. However, the immunosuppressive treatment may require a long course (up to 12 months. The increasing number of EAATD cases reported in the literature demonstrates a growing interest of the scientific community about this condition, which still requires a better definition of its pathophysiology, the diagnostic criteria, and the most appropriate management, including the long-term follow-up of patients. The current clinical evidence about EAATD is mostly based on the report of single cases or small cohort studies. In this review, we present the current knowledge about EAATD, with a dedicated focus to the clinical management of the patients from a diagnostic and therapeutic perspective.

    The three main areas of application of radionuclides in thyroid disease will be reviewed. Firstly thyroid radionuclide imaging in thyroid swellings, in relationship to lumps in the neck and ectopic thyroid tissue such as retrosternal goitre, and lingual goitre will be described. Future developments in the field including tomographic scanning, using the coded aperture method, and fluorescent scans and ultrasound are reviewed. The second area of application is the assessment and evaluation of thyroid function and the therapy of Grave's Disease and Plummer's Disease using radioiodine. The importance of careful collection of the line of treatment, results of treatment locally and the follow-up of patients after radioiodine therapy will be described. The third area of application is in the diagnosis and therapy of thyroid cancer. Investigation of thyroid swelling, and the diagnosis of functioning metastases are reported. The therapeutic iodine scan as the sole evidence of functioning metastatic involvement is recorded. Histological thyroid cancer appears to be increasingly encountered in clinical practice and the plan of management in relation to choice of cases for therapeutic scanning is discussed with case reports. Lastly the role of whole body scanning in relationship to biochemical markers is compared. In the changing field of nuclear medicine radionuclide applications in thyroid disease have remained pre-eminent and this is an attempt to reassess its role in the light of newer developments and local experience in the Institute of Radiotherapy, Oncology and Nuclear Medicine.

    The author's presentation on thyroid cancer around Chernobyl will focus on four different things. First will be the time trends, or the pattern of thyroid cancer occurrence before and after the accident. It is now very well known that the increase in thyroid cancer in children in several areas has been unprecedented. Second, the author discusses thyroid cancer in general and patterns of thyroid cancer around the world before the Chernobyl accident, including differences by age and pathology. Third, the author presents relatively crude analyses of risk according to dose to the thyroid gland. And last, the author attempts to contrast the findings for thyroid cancer in relation to the internal radioiodine dose in Chernobyl studies with analyses of the effects of external dose on thyroid cancer incidence. The bottom line to be developed is similar to that presented by Elaine Ron with regard to effects of external dose on thyroid cancer. The similarities between the childhood finding from Chernobyl studies and external radiation studies appear more remarkable than the differences

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months

    An International Workshop on Radiation and Thyroid Cancer took place on 21-23 February 2014 in Tokyo, Japan, to support the efforts of the Fukushima Prefecture and the Japanese government in enhancing public health measures following the Fukushima Daiichi nuclear power plant accident in March 2011. The workshop, which was designed to develop a state-of-the-art scientific understanding of thyroid cancer in children and of radiation-induced thyroid cancer (papillary carcinoma) in particular, was co-organised by the Japanese Ministry of the Environment (MOE), the Fukushima Medical University (FMU) and the OECD Nuclear Energy Agency (NEA). It brought together the world's top experts in the field, including medical doctors, epidemiologists and radiological risk assessment specialists from ten countries. Although rare, thyroid cancer occurs naturally, with the risk of developing a thyroid cancer increasing with age. Cases are usually identified when a thyroid carcinogenic nodule grows enough to be felt with a patient's fingers, at which point the patient visits a medical doctor to identify the nature of the growth. In many countries around the world, the incidence rate of naturally occurring thyroid cancer is on the order of less than 1 per year per 100 000 children (from ages 0 to 18). Statistically, this rate appears to be increasing in many countries, with young girls slightly more at risk than young boys. A second but very different means of detecting thyroid cancer cases is through thyroid ultrasound screening examinations on subjects who do not demonstrate any symptoms. Ultrasound screening is a more sensitive approach that can detect very small nodules (< 5 mm) and cysts (< 20 mm) which would not normally be perceived through simple palpitation. However, because thyroid ultrasound screening examinations are much more effective, the number of thyroid cancer cases per examination will normally be larger than the number per capita found through national cancer

    Thyroid storm (TS) is a rare life-threatening condition that is characterized by fever and altered mental status precipitated by endogenous or exogenous critical events, illness/injury, acute iodine load, and thyroid or non thyroid surgery. A large number of thyroid extracts are available and extensively used, even though they are not recommended clinically in hypothyroid or euthyroid patients. Consumption of such products can be dangerous and result in life-threatening TS. Here, we report a case of TS caused by inadvertent intake of very high dosages of triiodothyronine (T3) and thyroxine (T4) in compounded thyroid extracts. Plasmapheresis may be considered an option for the management of exogenous TS. A 62-year-old woman with no significant past medical history presented with severe myalgia, fever, tachycardia, and blood pressure of 170/80 mmHg, which precipitated to an altered mental state within 24 hours. Neurological examination did not reveal any focal deficit or any signs of meningeal irritation. Further investigation revealed that she had been taking thyroid supplements. The patient had accidentally been supplied with a batch of thyroid extract pills that had an inadvertently high content of T4. Her free T3 (FT3) and free T4 (FT4) levels were found to be very high beyond the laboratory readable range (FT3>30 pg/mL; FT4>6.06 ng/dL; thyrotropin [TSH]=0.07 IU/mL). Three days post commencement of standard conservative management of TS, the patient developed posterior reversible encephalopathy syndrome, resulting in a seizure. She remained unresponsive and in a poor mental state. The confirmed exogenous etiology for TS led to a decision to conduct plasmapheresis. Plasmapheresis conducted for two consecutive days proved successful as a therapeutic measure for TS and improved her thyroid profile as well as her mental state. The inappropriate use of thyroid extracts in euthyroid and hypothyroid patients can result in life-threatening TS. Plasmapheresis is probably

    Thyroid hormone is given therapeutically for the treatment of hypothyroidism and in goiterous conditions. When administered in full maintenance dosage, it interrupts the operation of the homeostatic mechanism that evokes excesses of thyrotropin (TSH) in response to various goiterogenic stimuli or impending thyroid failure, resulting in thyroid gland enlargement. All patients with treated thyroid cancer are maintained indefinitely on full replacement dosages of thyroid hormone to eliminate endogenous TSH and its trophic effect, thereby minimizing recurrence and growth of the tumor. A high-risk group of patients that were irradiated to the head and neck in childhood for various reasons are placed on thyroid hormone therapy prophylactically to turn off their endogenous TSH if they are found free of thyroid nodularity on initial evaluation. The adequacy of thyroid hormone therapy and the regularity of its intake can be ultimately evaluated by the thyrotropin releasing hormone (TRH) stimulation test, where no TSH response indicates adequate therapy and a normal TSH response suggests inadequate or irregular treatment

    TSH, was observed in 6 (26%) of our patients with positive thyroid antibodies during the first 6 months of follow up. There were no reported cases of recurrent or permanent hypothyroidism in our cohort study. Subacute thyroiditis is an uncommon disease that should be considered in the differential diagnosis of acute anterior neck pain, sore throat and fever especially in patients who do not respond to treatment. In the clinical setting, radioiodine uptake can help exclude other diseases, confirm the diagnosis and expedite the initiation of appropriate therapy to relieve symptoms. (author)

  13. PREGNANCY AND THYROID

    Full Text Available Background. In conditions with appropriate iodine intake, thyroid gland adapts to changes during pregnancy without any consequences. Fetal need for thyroid hormones in the first trimester is directly connected with transplacental transport of thyroid hormones. Fetal synthesis of thyroid hormones depends on availability of iodine in the feto-placental unit. Hypo- and hyperthyroidism during pregnancy are risk factors for pregnant woman and for normal development of fetus and child.Conclusions. Pregnant women with appropriately treated thyroid diseases have the same outcome of pregnancy as healthy women, and neuroendocrinological development of children is not impaired. If the disease is unrecognized or untreated, complications of pregnancy and delivery occur more frequently. Therefore, timely recognition and treatment of the diseases with appropriate drugs during pregnancy and, also, after delivery is very important.

    The objective of the present work was to study the influence of allelic variant associations of 1-beta interleukin (C3953T, &511C, T31C), interleukin-6 (C174G), and tumour necrosis factor-alpha (G308A) gene polymorphisms on the serum cytokine level in the patients presenting with chronic suppurative otitis media. A total of 299 patients at the age varying from 16 to 55 years with this condition divided into three groups were examined. Group 1 was comprised of 146 patients suffering from the tubotympanic form of chronic suppurative otitis media (CSOM). Group 2 was composed of 153 patients with epitympanic antral form of this condition. The control group included 183 subjects who have never suffered pathological changes in the middle ear. Human genomic DNA was analyzed with the use of the polymerase chain reaction (PCR). The serum cytokine levels were measured by the solid-state enzyme immunoassay in the beginning and at the end of the treatment period. The study has demonstrated that 56.2% of the healthy residents of the trans-Baikal region had the C/T Il-1b (C3953T) genotype. 79.1% of the patients presenting with the carious carious-destructive form of chronic suppurative otitis media were the heterozygous carriers of the T511C gene of 1-beta interleukin and had the maximally high concentrations of this interleukin in the blood serum. A rise in the production of the pro-inflammatory mediator (IL-6) was found to be related to the severity of the inflammatory process in the middle ear. The TNF-alpha content in the patients with CSOM during the active period of the disease proved to increase by a factor of 6 in comparison with that in the subjects of the control group irrespective of the type of mutation.

    Introduction: Thyroiditis presents with symptoms varying from thyrotoxicosis to hypothyroidism. In fairly a large number of patients the symptoms are very subtle and hence clinical diagnosis is difficult to make without laboratory assistance. In view of this we undertook a study to assess the patterns of clinical presentation and the behavioral pattern of patients with thyroiditis. Materials and Methods: Totally 43 patients were included in the study with clinical suspicion of thyroiditis. 31 patients presented with symptoms of thyrotoxicosis while 6 patients presented with hypothyroid symptoms. Six patients presented with history of acute upper respiratory tract infection with tender thyromegaly and euthyroid status. These patients were subjected to thyroid scan (43 patients), sonography (6 patients), thyroid antibody levels estimation (43 patients), FNAC evaluation (3 patients) and T3, T4, TSH estimation (43 patients). The patients were followed up for a period of 6 months to 2 years. Clinical evaluation and T3, T4 and TSH evaluation was performed. Result: 19 of the 31 patients (61.29%) who presented with thyrotoxicosis progressed to hypothyroid state both clinically and biochemically. 11 of the 31 patients (35.48%) reverted to euthyroid status. One patient continued to maintain thyrotoxic state at the end of 2 years and was treated with antithyroid measures. In the hypothyroid group of six patients, four patients continued to maintain hypothyroid state while two patients reverted to euthyroid status during follow up. In the euthyroid group of six patients four patients developed hypothyroid status and the other two patients remained euthyroid. The 99m- Tco4 scan demonstrated poor and patchy uptake in all the patients. Conclusion: Our study demonstrated that majority of the patients (72.09%) of thyroiditis present with thyrotoxic symptoms. The sequelae of hypothyroidism was seen in 61.29% of patients in this group. We observed an interesting finding of patients

  17. Thyroid hormone metabolism in poultry

    Darras V.M.

    2000-01-01

    Full Text Available Thyroid hormone (TH receptors preferentially bind 3.5,3'-triiodothyronine (T3. Therefore the metabolism of thyroxine (T4 secreted by the thyroid gland in peripheral tissues, resulting in the production and degradation of receptor-active T3, plays a major role in thyroid function. The most important metabolic pathway for THs is deiodination. Another important pathway is sulfation, which is a reversible pathway that has been shown to interact with TH deiodination efficiency. The enzymes catalysing TH deiodination consist of three types. Type 1 deiodinase (D1 catalyses both outer ring (ORD and inner ring deiodinalion (IRD. Type II deiodinase (D2 only catalyses ORD while type III (D3 only catalyses IRD. The three chicken deiodinase cDNAs have been cloned recently. These enzymes all belong to the family of selenoproteins. Ontogenetic studies show that the availability of deiodinases is regulated in a tissue specific and developmental stage dependent way. Characteristic for the chicken is the presence of very high levels off, inactivating D3 enzyme in the embryonic liver. Hepatic D3 is subject to acute regulation in a number of situations. Both growth hormone and glucocorticoid injection rapidly decrease hepatic D3 levels, hereby increasing plasma T3 without affecting hepatic D1 levels. The inhibition of D3 seems to be regulated mainly at the level of D3 gene transcription. The effect of growth hormone on D3 expression persists throughout life, while glucocorticoids start to inhibit hepatic D1 expression in posthatch chickens. Food restriction in growing chickens increases hepatic D3 levels. This contributes to the decrease in plasma T3 necessary to reduce energy loss. Refeeding restores hepatic D3 and plasma T3 to control levels within a few hours. It can be concluded that the tissue and time dependent regulation of the balance between TH activating and inactivating enzymes plays an essential role in the control of local T3 availability and hence in

    Few papers have shown that a hypoechoic appearance of the thyroid gland at ultrasonography (US) is related to a hypofunction and serum positivity of thyroid antibodies (T-Ab). However, it is not ascertained if normal thyroid appearance at US correspond to normal thyroid laboratory tests. The aim of this study was to assess the value of normal thyroid at US in predicting normal thyroid hormones and negative T-Ab in a cohort of 48 adult patients. All patients (37 females and 11 males) were referred to our hospital to undergo their first thyroid US examination, followed by a thyroid function evaluation. All subjects had normal thyroid gland at US. As a control group 65 patients with hypoechoic and inhomogeneous thyroid gland were enrolled. All 48 patients had normal free-T (3) and free-T (4) levels. While 41 patients (85.4%) showed normal TSH, in 7 subjects (14.6%) TSH was elevated and a significant (p thyroid volume or BMI. The multivariate model showed that only BMI was significantly correlated to thyroid volume (p thyroid recorded by US matches with normal thyroid laboratory assessment to a large degree. These preliminary data need to be confirmed in a prospective study and in a larger series and should suggest the evaluation of thyrotropin and thyroid antibodies in subjects with normal thyroid gland as assessed by US. © J.

    Amiodarone, a benzofuranic iodine-rich antiarrhythmic drug, causes thyroid dysfunction in 15-20% of cases. Amiodarone can cause both hypothyroidism (AIH, amiodarone-induced hypothyroidism) and thyrotoxicosis (AIT, amiodarone-induced thyrotoxicosis). AIH is treated by L-thyroxin replacement and does not need amiodarone discontinuation. There are two main forms of AIT: type 1, a form of true iodine-induced hyperthyroidism; and type 2, a drug-induced destructive thyroiditis. However, mixed/indefinite forms exist, contributed to by both pathogenic mechanisms. Type 1 AIT usually occurs in diseased thyroid glands, whereas type 2 AIT develops in substantially normal thyroid glands. Thioamides represent the first-line treatment for type 1 AIT, but iodine-replete glands are poorly responsive; sodium/potassium perchlorate, by inhibiting thyroidal iodine uptake, may increase the response to thioamides. Type 2 AIT is best treated by oral glucocorticoids. Response depends on thyroid volume and severity of thyrotoxicosis. Mixed/indefinite forms may require a combination of thioamides, potassium perchlorate, and steroids. Radioiodine treatment is usually not feasible because amiodarone-related iodine load decreases thyroidal radioiodine uptake. Thyroidectomy represents an important and helpful option in cases resistant to medical therapy. Surgery performed by a skilled surgeon may represent an emergent treatment in patients who have severe cardiac dysfunction.

    Thyroid ectopy is characterized by the presence of thyroid tissue outside its normal position resulting from a defect of the thyroid diverticulum migration from the base of the tongue until its final pre-tracheal position. One case is presented in a 12-year-old girl patient who consults for a failure to thrive estimated at less than three standard deviations (SD). Bone age was estimated at 8 years late compared to chronological age. The hormonal assessment showed hypothyroidism with negative thyroid antibodies. Cervical ultrasound was revealed thyroid parenchyma pre-dominantly left in place while sweeping the area under chin showed a nodular formation of the base of the tongue. Thyroid scan with technetium 99 m showed a selective uptake of radiotracer in sublingual position. Cervical computed tomography revealed a posterior median sublingual mass spontaneously hyperdense and enhancing sharply after injection of contrast. Treatment with thyroxine allowed obtaining euthyroidism. This case asks us to be careful before aetiological diagnosis of hypothyroidism in children, because although this is rare, the presence of a thyroid parenchyma up to the cervical ultrasound does not eliminate the presence of ectopic tissue

    Excessive iodine ingestion may cause thyroid dysfunction. In this case series, we report four patients who developed significant thyroid dysfunction after ingesting over-the-counter (OTC) drugs containing large concentrations of iodine. Four patients from a tertiary medical center are reported. Case 1 involved acute exacerbation of thyrotoxicosis induced by taking OTC Tri-iodine™ in a 35-year-old woman while still on methimazole therapy. Case 2 involved thyroid-extract-induced thyrotoxicosis following ingestion of Thyromine™, and was confirmed by laboratory studies and ¹³¹I thyroid uptake. Cases 3 and 4 involved severe, symptomatic hypothyroidism induced in 2 patients with underlying autoimmune thyroiditis (Hashimoto's disease) following ingestion of Iodoral™. In all cases, thyroid dysfunction resolved with appropriate management and discontinuation of the OTC drugs. These case reports demonstrate the significant risks associated with OTC preparations containing iodine in patients predisposed to thyroid dysfunction. There is no valid reason for taking high-dose OTC iodine supplements, which have been shown to cause harm and have no known benefit.

    We aimed to investigate the effects of thyroid hormone withdrawal on N-terminal prohormone forms of atrial natriuretic peptide (NT-proANP) and brain natriuretic peptide (NT-proBNP) during radioiodine therapy in female patients with differentiated thyroid cancer (DTC). Serum concentrations of thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), NT-proANP and NT-proBNP were measured in 51 female patients with DTC (48.7 ± 4.2 years) at three time-points: day of radioiodine therapy (t1 - under acute hypothyroidism), 5 days after radioiodine (t2 - under acute hypothyroidism) and 3 months after radioiodine (t3 - under TSH suppression). Thirty healthy euthyroid women served as controls (42.8 ± 5.6 years). At t1/t2/t3, median NT-proANP was 5.2/1.7/487 pmol/L vs. 297.7 pmol/L in control group (p thyroid hormone effects than NT-proBNP. Thyroid hormone-dependent hemodynamic effects seem to be overlapped on the direct stimulatory effect of thyroid hormones on NT-proANP secretion by cardiac myocytes.

    Autoimmune thyroid disease (AID) with reversible thyroid dysfunction was classified mainly by etiology. Hashimoto thyroiditis itself, pregnancy, cytokine therapy and various drugs, iodine-rich food and AID with TSH receptor antibody (TRAb) were main items. Silent or painless thyroiditis which was termed destructive thyroiditis occurs without clear cause or after adrenectomy for Cushing syndrome. Abnormal human chorionic gonadotropin (hCG) rarely causes transient thyrotoxicosis at early phase of pregnancy and postpartum thyroiditis which has similar symptom as silent thyroiditis is relatively common disorders. Thyroid dysfunction of patients with both TRAb (TSAb and TSBAb) is pathophysiologically unknown and the detection of both antibodies in a patient serum is difficult methodologically. We developed the highly sensitive TSAb assay by patients' IgG precipitated by high concentration PEG (22.5%) using porcine thyroid cell. This assay is also useful for detection of the coexistence cases of TSAb and TSBAb.

    Chemotherapy alone, either as a single drug or a combination of drugs with or without external radiation (ER) is useful for treatment of locally advanced disease and non iodine concentrating metastasis in differentiated thyroid cancers (DTC). The reported response is not encouraging, but the absence of better alternatives leave no choice for the treatment of such cases. However, for treatment of anaplastic thyroid cancers (ANC), chemotherapy (CT) in combination with ER results in local control. In medullary thyroid cancers (MTC), the results obtained with multimodal treatment are encouraging

    Amiodarone, an iodine-rich drug, results in mild disturbances of thyroid function in most patients and in thyroid dysfunction in approximately 20% of them. Hypothyroidism, mainly found in countries without iodine deficiency, is substituted with levothyroxine and does not need amiodarone to be discontinued. Hyperthyroidism, commonly found in areas of iodine deficiency, is more complex and usually motivates discontinuation of amiodarone. Type I hyperthyroidism, induced by iodine overload, is treated with antithyroid drugs, and type 2, resulting from the cytotoxic effect of amiodarone, may be treated with glucocorticoids. Considering the risk of thyroid dysfunction in patients treated with amiodarone, it is recommended to check regularly TSH level.

    Sixty-eight (68) patients with serious upper extremity suppurative infections, presenting within a period of fifteen (15) months, were prospectively studied clinically, Gram stain of aspirates/pus were performed, specimen cultured, planted, and where indicated glucose levels and haemoglobin genotype determined. Half of the patients had hand infections. Staphylococcus aureus was isolated from thirty-nine (39) patients. Gram Negative bacilli, including Salmonella were more isolated from patients with diabetes mellitus or Hgb SS or SC. The Gram stain results correlated with the culture result 90%. When Gram Positive cocci were demonstrated in the primary microscopic examination, cultures were not mandatory. When no organism was demonstrated on primary Gram stain or the patient was diabetic or a sickler, cultures of the specimens were done. The Gram stain, well performed, remains a useful, inexpensive, technologically appropriate laboratory test for abetting decision making in patients with upper extremity suppurative infections. Organisms encountered in this study included: Staphylococcus aureus, Streptococcus pyogenes, Salmonella typhi, Proteus mirabilis, Pseudomonas aeruginosa, and Coliforms.

    The aim of this study is to document the isolation of a hypermucoviscosity (HMV) phenotype of Klebsiella pneumoniae from 25 cases of suppurative pneumonia and pleuritis and two cases of abscesses in California sea lions (Zalophus californianus) from the central California coast, representing the first report of this zoonotic pathogen from the marine environment and only the second report in non-humans. Animals died 2h to 4 days after first being observed sick on beaches. Clinical signs varied from dyspnoea to coma. Gross post-mortem examination of 25 cases revealed fibrinous pleuritis, copious pus in the pleural cavity and suppurative bronchopneumonia. K. pneumoniae isolates obtained from lung and pleural swabs and the hepatic and subcuticular abscesses were highly mucoid on blood agar culture media and were positive to the "string test". Twenty-one of the 27 isolates were examined by PCR and all were positive for rmpA and K2wyz and negative for K1magA genes. Although pneumonia and pleuritis have previously commonly been observed in marine mammals, their association with pure cultures of a zoonotic bacteria, K. pneumoniae HMV phenotype, has not. This report provides further evidence of the role marine mammals play as sentinels of health risks to humans from coastal waters. Copyright 2009 Elsevier B.V. All rights reserved.

    To assess eustachian tubal function (ETF) preoperatively in patients with chronic suppurative otitis media (CSOM) with central perforation by performing the inflation-deflation test. To correlate the results of the inflation-deflation test with the finding of aditus patency or block in patients with CSOM STUDY DESIGN: Prospective, cohort Tertiary care hospital Eighty adult patients with chronic suppurative otitis media and central perforation were recruited into the study. There were 45 males and 35 females. All patients underwent preoperative inflation-deflation test followed by cortical mastoidectomy and tympanoplasty. The patency of the aditus was assessed intraoperatively. Equalization of pressure on inflation-deflation test and intraoperative assessment of aditus patency Of a total of 80 patients, 49 patients were found to have discharging ears and 31 had dry ears at the time of surgery. In dry ears the inflation-deflation test had a sensitivity of 93% in predicting aditus patency although the specificity was lower at 67%. In discharging ears the sensitivity in predicting aditus patency was 72% and the specificity was 67%. The eustachian tube inflation-deflation test is a sensitive test for predicting aditus patency in patients with dry ears but less so in patients with discharging ears. Hence, it could be used in the former to avoid unnecessary exploration of the mastoid.

    Thyroid ophthalmopathy is an autoimmune orbital disorder closely associated with Graves' disease, although both conditions may also occur isolatedly. Thyroid ophthalmopathy may precede, coincide or follow the thyroid dysfunction onset and may rarely occur in euthyroid and hypothyroid patients. The extra ocular muscles are most frequently involved and become enlarged resulting in ophthalmoplegia and proptosis. Other relevant signs include palpebral retraction, conjunctival hyperemia and periorbitary edema. Visual loss may occur in association with compressive optic neuropathy at the orbital apex. Thyroid ophthalmopathy is characterized by inflammation, congestion, hypertrophy and fibrosis involving fat and the orbital muscles. The disease activity is divided into two phases: an acute or inflammatory phase and a second one corresponding to an inactive phase associated with fibrotic changes and fat infiltration of the retrobulbar tissues. The diagnosis is based on clinical findings and imaging methods are indicated in case of doubt or suspicion of optic neuropathy. Computed tomography and magnetic resonance imaging can confirm the diagnosis, allowing the evaluation of the critical region of the orbital apex. Magnetic resonance imaging is the method of choice considering the superior tissue contrast resolution, besides the capacity of evaluating the disease activity by means of long TR sequences and detecting inflammatory changes, with a relevant role in a timely therapeutic planning, which may improve the prognosis.

    Thyroidal 99mTc uptake in the acute thyrotoxic phase of subacute thyroiditis (SAT) is always inhibited. However, a patient with SAT had signs in the right-side thyroid gland with transient thyrotoxicosis and slightly high 99mTc uptake levels in the right lobe, low 99mTc uptake in the left lobe, and normal overall uptake. Histological examination showed cellular destruction and granulomatous inflammatory changes in the right lobe, with marked interstitial fibrosis in the left lobe. The patient was thyrotrophin-receptor antibody (TRAb) positive. After a short course of prednisolone, SAT-like symptoms and signs improved. TRAb-positivity resolved spontaneously after 22 months, and TSH levels were slightly low for 22 months. Levels then kept normal in the following four years. In conclusion, high 99mTc uptake by the right lobe was due to the combined effects of TRAb and left thyroid gland fibrosis. (author)

    Thyroid hormones are crucial for organismal development and homeostasis. In humans, untreated congenital hypothyroidism due to thyroid agenesis inevitably leads to cretinism, which comprises irreversible brain dysfunction and dwarfism. Elucidating how the thyroid gland - the only source of thyroid hormones in the body - develops is thus key for understanding and treating thyroid dysgenesis, and for generating thyroid cells in vitro that might be used for cell-based therapies. Here, we review the principal mechanisms involved in thyroid organogenesis and functional differentiation, highlighting how the thyroid forerunner evolved from the endostyle in protochordates to the endocrine gland found in vertebrates. New findings on the specification and fate decisions of thyroid progenitors, and the morphogenesis of precursor cells into hormone-producing follicular units, are also discussed. © 2017.

    Human Immunodeficiency virus (HIV) infection and Acquired Immunodeficiency Syndrome (AIDS) are associated with dysfunction of many endocrine organs and their axis. HIV infectivity leads to altered metabolism, poor oral intake and increased prevalence of weight loss and wasting which may have a role in thyroid dysfunction. Overt thyroid dysfunction occurs at similar rates as the general population while subclinical disease such as nonthyroidal illness (sick euthyroid syndrome), subclinical hypothyroidism and isolated low T4 levels are more frequent. Moreover, HAART therapy can complicate thyroid function further through drug interactions and the immune reconstitution inflammatory syndrome (IRIS). In this review we report the common thyroid dysfunctions associated with HIV before and after HAART therapy. We discuss presentation, diagnostic work up, treatment and follow up in each condition.

    A case of Graves' disease occurring in a patient with hemiagenesis is presented. The detection of the rare occurrence of a congential hemiagenesis is often made by either clinical symptoms of thyroid dysfunction or anatomical abnormalities such as nodular goiter. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning and ultrasonography of an absent lobe. Anti-thyroid antibody studies documented the presence of Graves' disease within the remaining lobe. (orig.) [de

    1995-01-01

    The prevalence of thyroid diseases was studied in the ENT department of Kobe Teishin Hospital. Between January 1990 and June 1994, 6,348 outpatients (3,004 women and 3,344 men) visited the ENT department with problems of ear, nose, and throat. Among them 114 patients (82 women and 32 men) were revealed to have thyroid diseases (1.8%). The prevalence of thyroid diseases increased in patients over the age of 40 (4.6% for 40-80 year aged women, 1.6% for 40-80 year aged men). The male/female ratio was about 1:2.7. There was no subjective symptom in 86.8% of the patients. The prevalence of Hashimoto's thyroiditis was 53.5%, nontoxic diffuse goiter 16.7%, cyst(s) 8.8%, adenoma 7.0%, nontoxic nodular goiter 4.4%, subacute thyroiditis or acute exacerbation of Hashimoto's thyroiditis 4.4%, Graves' disease 1.8%, thyroid carcinoma 1.8%, adenomatous goiter 0.8%, and primary hypothyroidism 0.8%. Visible goiter was observed in only 5 patients and 93% of the patients had palpable but not visible thyroids. Therefore, it is important to palpate the thyroid gland during examination of the neck not only in women but also in men. Hashimoto's thyroiditis is thought to be increasing in frequency and is becoming a more important disease in the ENT clinic.

    We present the case of a 21-year-old man who was referred to us for parathyroid scintigraphy with high blood levels of intact parathormone and osteoporosis. Several methods and radiopharmaceuticals, e.g., Tc-99m MIBI and Tl-201 chloride/Tc-99m pertechnetate (Tl-201/TcPO{sup -4}) subtraction, are commonly used for this purpose. We present the case of a thyroid gland that demonstrates quite normal Tc-99m pertechnetate uptake, no accumulation of Tc-99m MIBI, and very low grade Tl-201 uptake. To the best of our knowledge, no similar case has been reported previously. A 21-year-old male with osteoporosis and growth-development retardation was referred for MIBI parathyroid scan because of high blood levels of intact parathormone and bone-specific alkaline-phosphatase, which were 219.4 (15-88 pg/ml) and 355 (21-58 U/L), respectively. In his Tc-99m pertechnetate (TcPO{sup -4}) pinhole scintigraphy, bilateral clearly visualized radioactivity accumulation in the thyroid gland was seen. In both early or late images of the Tc-99m MIBI parathyroid scan, the thyroid gland was not visualized. Therefore, a Tl-201/TcPO{sub -4} subtraction scan method was used. However, the Tl-201 accumulation level in the thyroid gland was not sufficient for the subtraction method. In his thyroid ultrasonography, the thyroid gland echo was homogenous, and there was neither any solid nor cystic lesion. The physical examination of his neck was normal. Other laboratory findings were all normal as follows. TSH: 3.03 (0.35-5.6 IU/mL), free T3: 3.66 (2.5-3.9 pg/mL), free T4: 0.90 (0.59-1.3 ng/dL), Anti-TPO:0.3 (0.40 IU/mL), Anti-TG-Ab: <2.2 (0-+u/L), TSH receptor Ab: 1.0 (0.14 U/L), osteocalcine: 9.13 (1.5-15 ng/dL), growth hormone: 1.3 (0.014-5.21), calcitonin:17 (0.150 ng/mL), sedimentation:6 (0.15 mm/h). There were no significant symptoms of acute or chronic thyroiditis. The cause for discordant uptake in the thyroid gland with T1-201 and Tc-99m MIBI scan could not be provided through clinical or

    Mahlstedt, J.

    1986-01-01

    Static images as isolated investigation in thyroid diagnosis mainly provides morphologic information, and therefore sonography is largely applied for this purpose. 99m Tc-pertechnetate scans or 123 I-scans are indicated in cases of malpositions and serve to clarify lesions of unknown dignity. Additionally 201 Tl-chloride is suited for examinations with regard to metabolically active thyroid tissue, whereby differential diagnostic laboratory tests must be carried out to exclude parathyroid adenoma. Dynamic thyroid scans before and after regulation tests (suppression, stimulation) reflect the physiological correlation between the iodine avidity of the thyroid, the peripheral thyroid hormone concentrations and the hypophyseal regulation in the TRH-test. The main application of this procedure is the clarification of thyroid autonomy, i.e. indication, detection, quantification or exclusion of thyroid autonomy. For the treatment of immunogenic thyrotoxicosis, dynamic thyroid scintigraphy provides important information about the onset of remission, thus permitting to end thyreostatic therapy. (orig.) [de

    Full Text Available Abstract Background Thyroid physiology is closely related to oxidative changes. The aim of this controlled study was to evaluate the levels of nutritional anti-oxidants such as vitamin C, zinc (Zn and selenium (Se, and to investigate any association of them with parameters of thyroid function and pathology including benign and malignant thyroid diseases. Methods This controlled evaluation of Se included a total of 1401 subjects (1186 adults and 215 children distributed as follows: control group (n = 687, benign thyroid disease (85 children and 465 adults; malignant thyroid disease (2 children and 79 adults. Clinical evaluation of patients with benign thyroid disease included sonography, scintigraphy, as well as the determination of fT3, fT4, TSH, thyroid antibodies levels, Se, Zn, and vitamin C. Besides the routine oncological parameters (TG, TSH, fT4, ultrasound Se was also determined in the cases of malignant disease. The local control groups for the evaluation of Se levels were taken from a general practice (WOMED as well as from healthy active athletes. Blood samples were collected between 8:00 and 10:30 a.m. All patients lived in Innsbruck. Statistical analysis was done using SPSS 14.0. The Ho stated that there should be no differences in the levels of antioxidants between controls and thyroid disease patients. Results Among the thyroid disease patients neither vitamin C, nor Zn nor Se correlated with any of the following parameters: age, sex, BMI, body weight, thyroid scintigraphy, ultrasound pattern, thyroid function, or thyroid antibodies. The proportion of patients with benign thyroid diseases having analyte concentrations below external reference cut off levels were 8.7% of cases for vitamin C; 7.8% for Zn, and 20.3% for Se. Low Se levels in the control group were found in 12%. Se levels were significantly decreased in cases of sub-acute and silent thyroiditis (66.4 ± 23.1 μg/l and 59.3 ± 20.1 μg/l, respectively as well as in

    Okamoto, Kyoko; Imanishi, Yoshimasa; Nakaji, Shunsuke; Shinagawa, Toshihito

    2007-01-01

    Imanishi et al. have previously reported that the changes in CT values reveal not only the change in iodine concentration in thyroid follicles, but also represent secondary changes in follicular content and follicular cells and/or interstitial structures. Thus, we performed thyroid CT without contrast material in 138 controls, 417 cases with diffuse thyroid diseases, and 279 cases with thyroid nodules, and evaluated the CT images based on the relation between the change in CT values and pathological changes. In 89% of the controls and 43% of patients with diffuse thyroid diseases, the thyroid CT revealed diffuse high density. In contrast, the 94% of thyroids that demonstrated diffuse low density were from patients with diffuse thyroid diseases. Eighty-four percent of malignant nodules and 64% of benign nodules had inhomogeneous densities, and only 26% of benign thyroid nodules had homogeneous density. However, 71% of nodules that showed high and low densities with regular and clear borders, and 82% of nodules that showed papillary proliferation in a cyst pattern were benign. Although only 58% of nodules with calcification were malignant, 66% of nodules with calcification in the central portion, and 86% of nodules with calcification of a disseminated and convergent pattern in distribution were malignant. Sixty-two percent of thyroids that surrounded nodules had chronic thyroiditis, hypoplasia and/or adenomatous goiter. Thus, unclear borders between a nodule and the surrounding thyroid tissue did not increase the possibility of malignancy. However, the unclear and/or lobulated border between a nodule and extra thyroid tissue increased the possibility of malignancy. We concluded that thyroid CT without contrast material is useful for the diagnosis of thyroid diseases. (author)

    Full Text Available Diseases of the salivary glands is one of the most frequent pathologies among dental patients. Salivolithiasis is most common among the diseases of the salivary glands. Half of the patients after the surgery relapse stone formation. One of the etiological causes salivolithiasis is a violation of mineral metabolism. Known effects of thyroid hormones on the balance of bone remodeling. The aim of our study was to improve treatment of patients with salivolithiasis in thyroid pathology. Materials and methods. To determine thyroid function in patients were studied: thyroid-stimulating hormone (TSH, free thyroxine (free T4.. State of mineral metabolism was assessed by content in the blood calcium-regulating hormones parathyrin (PTH (pg / ml and calcitonin (CAT (pg / ml, a marker of bone resorption-Cross laps (ng / ml and bone formation - osteocalcin (ng / ml. Postoperatively, the patients were divided into two groups: the first consisted of patients with preoperative correction of thyroid status at the doctor, endocrinologist, the second (control - without preoperative correction of thyroid status doctor endocrinologist. Results. In the control group of patients compared with the group that received the necessary correction, much heavier passed the postoperative period. Output. Reasonable pharmacological correction in violation of mineral metabolism in patients with calculous sialadenitis is the best procedure that can reduce the number of complications such as acute exacerbations of chronic sialadenitis.

  13. On the RET Rearrangements in Chernobyl-Related Thyroid Cancer

    Directory of Open Access Journals (Sweden)

    Sergei V. Jargin

    2012-01-01

    Full Text Available There is a consensus that Chernobyl accident has induced thyroid cancer increase in children and adolescents. The UNSCEAR report concluded that no somatic disorders other than thyroid cancer were caused by radiation exposure due to the accident except for acute radiation sickness occurred to the people within the Power Plant at the time of the accident. A hypothesis is discussed in this paper that the increase of thyroid cancer was caused predominantly by the screening, overdiagnosis, and registration of nonirradiated persons as Chernobyl victims. A mechanism of thyroid cancer overdiagnosis is described that can be active even today, causing hypertherapy. Older neglected tumors found by the screening shortly after the Chernobyl accident or brought from noncontaminated areas were misclassified as aggressive radiation-induced cancers. Therefore, supposed markers of the radiation-induced thyroid cancer, such as the RET rearrangements, are probably associated with disease duration and tumor progression. The screening effect is obviously dependent on the basis level of medical surveillance: the higher the level, the smaller the screening effect. Absence of any significant increase of thyroid cancer after the Fukushima accident in spite of the vigorous screening would certify the high level of health care in Japan especially for children.

    Full Text Available Malignant tumors of the thyroid gland account for about 1% of thenewly diagnosed malignant tumors each year, and their incidence inwomen is twice the incidence in men. According to the WHO classification (2004 thyroid tumors are divided into: carcinoma of the thyroid, adenoma and similar tumors, and other thyroid tumors which include: teratomas, angiosarcomas, paragangliomas and others, as well as primary lymphomas and plasmacytomas. Primary thyroid lymphomasare defined as lymphomas which originate in the thyroid gland. This study presents the case of a 68-year-old patient with a thyroid lymphoma, which caused compression of the airways. In the patientpresented there was reduced activity of the thyroid gland. The dominant symptoms were: breathing difficulties, hoarse voice and the enlargement of the thyroid. An ultrasound examination was performedbefore surgery on the neck, which showed a multinodular thyroid,with compromised and compressed trachea to the right and rear. Anemergency surgical procedure was performed to reduce the tumor.Pathohistological diagnosis confirmed diffuse large B cell lymphoma.The aim of the study was to present a patient with a thyroid lymphoma, who had previously not had any immunological changes to the gland,that is, she had not had any chronic lymphocyte thyroiditis, but due to the compressive syndrome it was necessary to perform an emergencysurgical procedure to reduce the tumor.

    Several changes in thyroid hormone secretion, metabolism, and action occur with the increase in age. Aging is often associated with a decrease in serum thyroid stimulating hormone and T3 levels, whereas serum free T4 levels usually remain unchanged. The prevalence of thyroid dysfunction is higher in the elderly as compared to the younger population. In elderly individuals the non-specific clinical manifestations of thyroid hormone excess or deprivation can cause confusion in the clinical setup; while some of the symptoms of thyroid disease are similar to those in younger patients, it is not uncommon for both hyperthyroidism and hypothyroidism to be manifested in subtle ways in older patients, often mimicking symptoms of aging or masquerading as diseases of the cardiovascular, gastrointestinal, or nervous system. In addition, diagnosis of thyroid disorders is commonly complicated, due to chronic, non-thyroidal illness or medication therapy. Early diagnosis and treatment of overt thyroid disorders is crucial, since these disorders are associated with increased morbidity and mortality in the elderly, usually due to common coexistent diseases such as diminished cardiovascular reserve. Treatment of subclinical thyroid disease should also be considered, based on a combination of age, symptoms and risk factors in the individual patients. In addition, both prevalence and aggressiveness of thyroid cancer increase with age. This review summarizes the changes of thyroid function, as well as the clinical manifestations and treatment of thyroid disorders with advancing age. Copyright © 2011 Elsevier Ireland Ltd.

    Recent clinical practice guidelines on thyroid dysfunction and pregnancy have changed health care provided to pregnant women, although their recommendations are under constant revision. Trimester- and area-specific reference ranges for serum thyroid-stimulating hormone are required for proper diagnosis of hypothyroidism and hyperthyroidism. There is no doubt on the need of therapy for overt hypothyroidism, while therapy for subclinical hypothyroidism is controversial. Further research is needed to settle adverse effects of isolated hypothyroxinemia and thyroid autoimmunity. Differentiation between hyperthyroidism due to Graves' disease and the usually self-limited gestational transient thyrotoxicosis is critical. It is also important to recognize risk factors for postpartum thyroiditis. Supplementation with iodine is recommended to maintain adequate iodine nutrition during pregnancy and avoid serious consequences in offspring. Controversy remains about universal screening for thyroid disease during pregnancy or case-finding in high-risk women. Opinions of some scientific societies and recent cost-benefit studies favour universal screening. Randomized controlled studies currently under development should reduce the uncertainties that still remain in this area. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Indirect thyroid lymphography with water-soluble radiographic agents has been applied. This method allows contrast lymph microvessels of the thyroid gland, providing the detection of volume formations of 0.3 to 0.4 cm and more in diameter. 232 patients with different thyroid diseases were examined. Different rate of the water-soluble contrast agent resolution in diffuse toxic and nodular goiter, thyroid cancer, chronic thyroiditis is of great importance in differential diagnosis of these diseases. This method provides necessary information on the organs inner structure, its topography and size [ru

    We report an extremely rare case of papillary thyroid microcarcinoma (PTMC) in the thyroid pyramidal lobe (TPL). A 48-year-old woman underwent ultrasound-guided fine-needle aspiration for a small thyroid nodule in the right lobe in local clinic, and it revealed a malignant cytology. On preoperative ultrasonography for tumor staging in our hospital, another small suspiciously malignant hypoechoic nodule was detected in the left TPL. Total thyroidectomy and central nodal dissection were performed. Histopathology confirmed PTMCs in the left TPL and both thyroid lobes. Ultrasonography for TPL should be required for complete evaluation of possible multifocality of thyroid malignancy.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

  3. Lugol’s solution-induced painless thyroiditis

    Full Text Available Lugol’s solution is usually employed for a limited period for thyroidectomy preparation in patients with Graves’ disease and for the control of severe thyrotoxicosis and thyroid storm. We describe a rare case of Lugol’s solution-induced painless thyroiditis. In November 2014, a 59-year-old woman was prescribed Lugol’s solution four drops per day for the alleviation of menopausal symptoms. She was referred to our clinic in June 2015 for fatigue, hair loss, and a 20-lb weight loss without thyroid pain or discomfort. Physical examination revealed a normal thyroid gland. On 7 May 2015, laboratory tests revealed a suppressed thyroid-stimulating hormone (TSH 0.01 U/L with elevated free T4 3.31 ng/dL (42.54 pmol/L. Repeat testing on 25 May 2015 showed spontaneous normalization of the free thyroid hormone levels with persistently low TSH 0.10 U/L. Following these results, a family physician prescribed methimazole 10 mg PO TID and very soon after, the TSH concentration rose to >100 U/L along with subnormal free T4 and T3 levels. Methimazole was promptly discontinued, namely within 18 days of its initiation. Over the course of the next few months, the patient spontaneously achieved clinical and biochemical euthyroidism. To our knowledge, this is a unique case of painless thyroiditis induced by Lugol’s solution, which has not been reported before. Lugol’s solution is a short-term medication given for the preparation of thyroidectomy in patients with Graves’ disease and for the control of severe thyrotoxicosis. Iodine excess can cause both hyperthyroidism and hypothyroidism. Rarely, Lugol’s solution can cause acute painless thyroiditis.

    The recommended daily intake of iodide, is 150 μg for adolescents and adults, 250 μg for pregnancy and lactation. Thyroid gland is an effective collector of iodine. The active iodine uptake along the basolateral membrane of thyroid cell is followed by its transport to the apical edge of the cell and then to the follicle lumen. TSH acts through cAMP and stimulates NIS gene expression and protein synthesis. The major proportion of iodine in the thyroid gland is bound to Thyroglobulin. The non-organic intrathyroidal iodine is usually low, but significantly greater compared to plasma. Large doses of iodine reduce both the uptake and the organification (Wolff-Chaikoff effect) and cause partial inhibition of Tg proteolysis. The thyroid gland has several protective mechanisms resulting on the maintenance of normal thyroid function despite wide fluctuations of the daily iodine intake. Ingestion of several commonly used drugs and food conservatives results in acute or chronic excessive iodine intake. Failure to escape from the iodine induced organification inhibition can cause hypothyroidism, which is temporary and subsides after iodine exposure ceases. Iodine excess may also establish a status of excessive thyroid hormone synthesis and release, thus inducing autonomic thyroid function in iodopenic areas or can contribute to the development of iodine-induced hyperthyroidism in iodine abundant areas. The anti-arrhythmic Amiodarone, is a benzofuranic product with a very high iodine content, is associated with either hypo- or hyperthyroidism development. In the presence of defective auto-protective mechanisms, excessive iodine ingestion can divert the normal thyroid function.

    Although most patients remain clinically euthyroid, some develop amiodarone-induced hyperthyroidism (HPEAI) or hypothyroidism (HPOAI). The authors present a retrospective analysis of ten patients with amiodarone-induced thyroid dysfunction. Six patients were female and mean amiodarone intake was 17.7 months. HPOIA was more common (six patients). From all the patients with HPEAI, two had type 2, one had type 1, and one had type 3 hyperthyroidism. Symptoms suggestive of thyroid dysfunction occurred in five patients, most of them with HPOAI. In HPEAI, the most frequent symptom was exacerbation of arrhythmia (three patients). Discontinuation of amiodarone and treatment with levothyroxine was chosen in 83.3% of the HPOAI cases, while thyonamide treatment with corticosteroids and without amiodarone was the option in 75% of the HPEAI cases. There were three deaths, all in patients with HPEAI. HPEAI is potentially fatal. The clinical picture may be vague, so the thyroid monitoring is mandatory.

    Full Text Available In this article, we present a case of subacute thyroiditis occurring in the first trimester of pregnancy in a 33-years-old pregnant patient. Thyrotoxicosis during pregnancy is a rare condition and occurs in 0.1 to 0.4% of all pregnancies. Graves' Disease and transient gestational thyrotoxicosis constitute the majority of emerging thyrotoxicosis during pregnancy. Subacute thyroiditis may also cause temporary thyrotoxicosis. Although the majority of the patients recover without treatment, complications in the pregnancy should be considered and each patient must be evaluated individually. As a result, differential diagnosis of thyrotoxicosis in pregnancy and treatment plan should be done well and subacute thyroiditis should be considered in differential diagnosis.

    Amiodarone is an effective medication for the treatment of cardiac arrhythmias. Originally developed for the treatment of angina, it is now the most frequently prescribed antiarrhythmia drug despite the fact that its use is limited because of potential serious side effects including adverse effects on the thyroid gland and thyroid hormones. Although the mechanisms of action of amiodarone on the thyroid gland and thyroid hormone metabolism are poorly understood, the structural similarity of amiodarone to thyroid hormones, including the presence of iodine moieties on the inner benzene ring, may play a role in causing thyroid dysfunction. Amiodarone-induced thyroid dysfunction includes amiodarone-induced thyrotoxicosis (AIT) and amiodarone-induced hypothyroidism (AIH). The AIT develops more commonly in iodine-deficient areas and AIH in iodine-sufficient areas. The AIT type 1 usually occurs in patients with known or previously undiagnosed thyroid dysfunction or goiter. The AIT type 2 usually occurs in normal thyroid glands and results in destruction of thyroid tissue caused by thyroiditis. This is the result of an intrinsic drug effect from the amiodarone itself. Mixed types are not uncommon. Patients with cardiac disease receiving amiodarone treatment should be monitored for signs of thyroid dysfunction, which often manifest as a reappearance of the underlying cardiac disease state. When monitoring patients, initial tests should include the full battery of thyroid function tests, thyroid-stimulating hormone, thyroxine, triiodothyronine, and antithyroid antibodies. Mixed types of AIT can be challenging both to diagnose and treat and therapy differs depending on the type of AIT. Treatment can include thionamides and/or glucocorticoids. The AIH responds favorably to thyroid hormone replacement therapy. Amiodarone is lipophilic and has a long half-life in the body. Therefore, stopping the amiodarone therapy usually has little short-term benefit. © The Author(s) 2013.

  8. Selenium supplementation in thyroid associated ophthalmopathy:an update

    Full Text Available The therapeutic effect of selenium (Se has already been proven in thyroid disease and thyroid associated ophthalmopathy (TAO. In spite of clear scientific proof of its benefits in TAO, there appears to be no clear agreement among the clinicians regarding its optimum dose, duration of the treatment, efficacy and safety to date. In this review, the author summarises the findings of 135 English language articles published on this subject over the past four decades from 1973 to 2013. The regulation and metabolism of thyroid hormones require a steady supply of Se and recent studies have revealedseveral possible mechanisms by which Se improves the severity of thyroid disease and TAO. These mechanisms include 1 inhibitory effect of HLA-DR molecule expression on thyrocytes; 2 profound reductions of thyroid stimulating hormone (TSH receptor antibodies (TSHR-Ab and TPO antibodies (TPO-Ab; 3 prevention of dysregulation of cell-mediated immunity and B cell function; 4 neutralising reactive oxygen species (ROS and inhibition of redox control processes required for the activation, differentiation and action of lymphocytes, macrophages, neutrophils, natural killer cells involved in both acute and chronic orbital inflammation in TAO; 5 inhibition of expression of pro-inflammatory cytokines and 6 inhibition of prostaglandin and leukotriene synthesis. An increased oxidative stress has been observed in both acute and chronic phases of thyroid disease with raised tissue concentrations of ROS. The benefits of Se supplementation in individuals with TAO appear to be proportionate to the degree of systemic activity of the thyroid disease. The maximal benefit of Se supplementation is therefore seen in the subjects who are hyperthyroid. Restoration of euthyroidism is one of the main goals in the management of TAO and when anti-thyroid drugs are combined with Se, the patients with Graves’ disease (GD and autoimmune thyroiditis (AIT achieved euthyroidism faster than

    Abnormalities in the circulating levels of thyroid hormones, without evidence of coexisting thyroid or pituitary gland disease can be observed in all general diseases. These nonthyroidal illnesses (NTIS) are the result of complex mechanisms that combine the effect of some drugs, cytokines, nutritional and endocrine factors at all levels of the thyrotropic axis, from the hypothalamus to the cellular transporters and nuclear receptors of thyroid hormones. The patterns of NTIS depend on the underlying disease and its severity. Thirtyfive years after the initial description, the pathophysiological significance of these anomalies remains controversial. One of the dilemma of NTIS is whether the hormone responses represent an adaptive and normal, physiologic response to conserve energy and protect against hypercatabolism in case of aggression, or whether it is a maladaptive response contributing to a worsening of the disease. This debate is not just a theoretical question, because in the first case the process must be respected, in the other case a vigorous treatment to restore circulating thyroid hormone levels is justified. There have been very few clinical studies designed to address whether the substitution with thyroid hormone is advantageous, and there is at current time no permissive evidence for the use of thyroid hormone replacement in patients with NTIS. But the clinical context, the choice of the molecule or of the dose and the way of administration were not necessarily the most relevant. Theoretically, stimulation of thyreotrope axis used a continuous infusion of TRH seems to provide clinical benefit. With the expectation that randomized clinical trials will provide demonstration of NTIS treatment efficiency, the question might remain unanswered for several more years.

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    2017-12-01

    This review summarises molecular pathological techniques applicable to thyroid FNA. The molecular pathology of thyroid tumours is now fairly well understood. Molecular methods may be used as a rule-in test for diagnosis of malignancy in thyroid nodules, eg BRAF V600E point mutation, use of a seven-gene mutational panel (BRAF V600E, RAS genes, RET/PTC or PAX8/PPARG rearrangement), or as a comprehensive multigene next-generation sequencing panel, eg ThyroSeq v2. Molecular methods can also be applied as rule-out tests for malignancy in thyroid nodules, eg Afirma or ThyroSeq v2 or as markers of prognosis, eg TERT promoter mutation or other gene mutations including BRAF V600E, TP53 and AKT1, and as tests for newly defined tumour entities such as non-invasive follicular thyroid neoplasm with papillary like nuclei, or as a molecular marker(s) for targeted therapies. This review describes practical examples of molecular techniques as applied to thyroid FNA in routine clinical practice and the value of molecular diagnostics in thyroid FNA. It describes the range of molecular abnormalities identified in thyroid nodules and thyroid cancers with some practical applications of molecular methods to diagnosis and prognosis of thyroid nodules and thyroid cancer. © 2017 John Wiley & Sons Ltd.

    Pineal hormone and thyroid functions, were studied simultaneously in rats after the induction of acute psychic stress as well as exogenous administration of melatonin, thyroxine and also after thyroidectomy. A gradual increase in 131 I uptake, serum PBI and melatonin levels were observed in blood, reaching maximum on 8th day of psychic stress. Melatonin administration resulted in hypothyroidism whereas thyroxine increased the activity of pineal qland. Thyroidectomy revealed a gradual decrease in melatonin content of pineal gland whereas supplementation with thyroxine resulted in a melatonin content similar to that observed in sham operated (control) group.

    Environmental factors are determinant for the appearance of autoimmune thyroid diseases (AITD) in susceptible subjects. Increased iodine intake, selenium, and vitamin D deficiency, exposure to radiation, from nuclear fallout or due to medical radiation, are environmental factors increasing AITD. Cigarette smoking is associated with Graves' disease and Graves' ophthalmopathy, while it decreases the risk of hypothyroidism and thyroid autoimmunity. Viral infections are important environmental factors in the pathogenesis of AITD, too, particularly human parvovirus B19 (EVB19) and hepatitis C virus. Among the many chemical contaminants, halogenated organochlorines and pesticides variably disrupt thyroid function. Polychlorinated biphenyls and their metabolites and polybrominated diethyl ethers bind to thyroid transport proteins, such as transthyretin, displace thyroxine, and disrupt thyroid function. Among drugs, interferon- and iodine-containing drugs have been associated with AITD. Moreover intestinal dysbiosis causes autoimmune thyroiditis. To reduce the risk to populations and also in each patient, it is necessary to comprehend the association between environmental agents and thyroid dysfunction.

  15. Molecular mechanisms of thyroid tumorigenesis

    Thyroid nodules are the most frequent endocrine disorder and occur in approximately 30% of the German population. Thyroid nodular disease constitutes a very heterogeneous entity. A striking diversity of possible functional and morphological features of a thyroid tumour derived from the same thyroid ancestor cell, is a hallmark of thyroid tumorigenesis and is due to specific genetic alterations. Defects in known candidate genes can be found in up to 70% of differentiated thyroid carcinomas and determine the respective cancer phenotype. Papillary thyroid cancers (PTC) harbour BRAF (or much less frequently RAS) mutations in sporadically occurring tumours, while radiation-induced PTC display chromosomal rearrangements such as RET, TRK, APR9 / BRAF. These genetic events results in constitutive MAPKinase activation. Follicular thyroid cancers (FTC) harbour RAS mutations or PAX8/ PPARγ rearrangements, both of which, however have also been identified in follicular adenoma. In addition, recent studies show, that activation of PI3K/AKT signalling occurs with high frequency in follicular thyroid tumours. Undifferentiated (anaplastic) thyroid cancers (ATC) display genetic features of FTC or PTC, in addition to aberant activation of multiple tyrosinkinase pathways (overexpression or mutations in PI3K and MAPK pathways). This underscores the concept of a sequential evolution of ATC from differentiated thyroid cancer, a process widely conceived to be triggered by p53 inactivation. In contrast, the molecular pathogenesis of benign thyroid tumours, in particular cold thyroid nodules is less known, except for toxic thyroid nodules, which arise from constitutive activation of cAMP signalling, predominantly through TSHR mutations.

    2007-01-01

    Primary thyroid lymphoma (PTL) is a rare disease with heterogeneous histological and clinical characteristics. As a result, diagnosis and subsequent management of the disease is difficult. PTL occurs most commonly in the thyroid glands with a background of Hashimotos thyroiditis. The clinical presentation was usually an enlarging neck mass squeezing the surrounding structures. Most patients can be diagnosed by fine-needle aspiration (FNA) followed by immuno phenotypic analysis, obviating the need for open surgical biopsy. Main histopathologic subtypes are either diffuse large B cell lymphomas (DLBCL) or mucosa-associated lymphoid tissue (MALT). Patients with localised, low-grade MALT lymphomas may be treated with surgery. Postoperative chemotherapy or radiotherapy is necessary in some patients. Systemic chemotherapy is the optimal treatment for DLBCL. In this group surgery may be used for palliative debulking to alleviate obstructive symptoms. Prognosis for MALT lymphoma is good. Diffuse large B cell lymphoma patients have poor prognosis (5-yr survival <50%). What should be stressed here is that patients with rapidly growing nodular goitre with or without cervical adenopathy should always be examined for primary thyroid lymphoma. (authors)

    Full Text Available Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves’ disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy. To assess the activity of the ophthalmopathy and response to treatment, clinical activity score, which includes manifestations reflecting inflammatory changes, can be used. Supportive approaches can control symptoms and signs in mild cases. In severe active disease, systemic steroid and/or orbital radiotherapy are the main treatments. In inactive disease with proptosis, orbital decompression can be preferred. Miscellaneous treatments such as immunosuppressive drugs, somatostatin analogs, plasmapheresis, intravenous immunoglobulins and anticytokine therapies have been used in patients who are resistant to conventional treatments. Rehabilitative surgeries are often needed after treatment.

    Hurtado-Hernández, Z; Segura-Domínguez, A

    2013-01-01

    Postpartum thyroiditis (PPT) is a transient thyroid dysfunction of autoimmune origin that can occur in the first year postpartum in women who have not been previously diagnosed with thyroid disease. It may start with clinical thyrotoxicosis followed by hypothyroidism and the subsequent recovery of thyroid function, or may just appear as isolated thyrotoxicosis or hypothyroidism. PPT recurs in high percentage of patients after subsequent pregnancies. Many women develop permanent hypothyroidism sometime during the 3 to 10 year period after an episode of PPT. It is important for family physicians to be familiar with this disease, due to its high prevalence in order to make a correct diagnosis and therapeutic intervention. Family doctors also play a crucial role in the monitoring of these patients, given the negative implications of established hypothyroidism on reproduction in the female population during their reproductive years. This article reviews the principle characteristics of PPT along with its diagnosis and treatment. Copyright © 2012 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    Full Text Available Background: Pregnancy has a huge impact on the thyroid function in both healthy women and those that have thyroid dysfunction. The prevalence of thyroid dysfunction in pregnant women is relatively high. Objective: The objective of this review was to increase awareness and to provide a review on adverse effect of thyroid dysfunction including hyperthyroidism, hypothyroidism and thyroid autoimmune positivity on pregnancy outcomes. Materials and Methods: In this review, Medline, Embase and the Cochrane Library were searched with appropriate keywords for relevant English manuscript. We used a variety of studies, including randomized clinical trials, cohort (prospective and retrospective, case-control and case reports. Those studies on thyroid disorders among non-pregnant women and articles without adequate quality were excluded. Results: Overt hyperthyroidism and hypothyroidism has several adverse effects on pregnancy outcomes. Overt hyperthyroidism was associated with miscarriage, stillbirth, preterm delivery, intrauterine growth retardation, low birth weight, preeclampsia and fetal thyroid dysfunction. Overt hypothyroidism was associated with abortion, anemia, pregnancy-induced hypertension, preeclampsia, placental abruption, postpartum hemorrhage, premature birth, low birth weight, intrauterine fetal death, increased neonatal respiratory distress and infant neuro developmental dysfunction. However the adverse effect of subclinical hypothyroidism, and thyroid antibody positivity on pregnancy outcomes was not clear. While some studies demonstrated higher chance of placental abruption, preterm birth, miscarriage, gestational hypertension, fetal distress, severe preeclampsia and neonatal distress and diabetes in pregnant women with subclinical hypothyroidism or thyroid autoimmunity; the other ones have not reported these adverse effects.

    For the purposes of radiation protection, the noteworthy risk of thyroid is carcinogenesis. The risk factor which ICRP presented in the publication-26 is 5 x 10 - 6 rem - 1 . This numerical value is based upon the estimated likelihood of inducing fatal thyroid cancer. On the other hand, the risk factor presented by the BEIR report is 4 x 10 - 6 yr - 1 . This value was decided after consideration of the risks of both fatal and non-fatal cancer of thyroid. The following features distinguished thyroid cancer from malignancy of other tissue from medical point of view. 1) A large difference between incidence and mortality in case of thyroid cancer is recognized, because the thyroid cancer could be successfully treated by surgical or radiological treatment. 2) The high prevalence of clinically silent tumor in thyroid gland has been reported. The incidence of thyroid cancer, therefore, is very dependent on methods of medical inspection. The prevalence of radiation induced thyroid cancer is modified by various factors such as age, sex, latency, dose and dose rate. The latent period is very important factors such as ave, sex, latency, dose and dose rate. The latent period is a very important factor in the estimation of accumulated total risk of thyroid malignancy. What is included in the risk caused by thyroid irradiation must be investigated. The risk of non-fatal cancer should be considered in the same way as that of fatal cancer. The dose-equivalent limit of thyroid in non-uniform irradiation caused by radioactive iodine is decided by the limit for non-stochastic effects. Therefore the further consideration of non-stochastic effects of thyroid is necessary. (author)

    This systematic review aimed to establish that quinolones are as effective as aminoglycosides when used to treat chronic suppurative otitis media. The review included good quality, randomised, controlled trials on human subjects, published in English, that compared topical aminoglycosides with topical quinolones for the treatment of chronic suppurative otitis media. Nine trials met the criteria. Two studies showed a higher clinical cure rate in the quinolone group (93 per cent vs 71 per cent, p = 0.04, and 76 per cent vs 52 per cent, p = 0.009). Four studies showed no statistically significant difference in clinical outcome. A significant difference in microbiological clearance in favour of quinolones was shown in two studies (88 per cent vs 30 per cent, p otitis media and when used as prophylaxis post-myringotomy. Topical quinolones should be considered a first-line treatment for these patients.

    The incidence of thyroid autoantibodies is clearly increased in patients with differentiated thyroid cancer. The aim of this study was to re-evaluate frequency and evolution of anti-thyroglobulin and anti-microsomal (anti-peroxidase) autoantibodies in 662 patients with thyroid carcinoma treated with 131 radioiodine. Ours results obtained with 'classical' methods confirmed others earlier reports. When using more sensitive methods to detect thyroglobulin antibodies we obtained an increase in positive results and a more frequent association with anti-microsomal antibodies. Antibodies became undetectable with a variable period, ranging from a few months to 13 years in one case. If we suppose that the disappearance of antibodies is linked to the thyroid tissue disappearance, thyroid cancer follow up ought to include anti-thyroglobulin and anti-peroxidase antibodies, both directed against thyroid antigens. A decrease of both antibodies seems to indicate a favorable prognostic factor whereas an increase may suggest relapse. (author)

    The American Thyroid Association guidelines on thyroid nodules and differentiated thyroid cancer, published in 2009, provide valuable recommendations based on current evidence. Inevitably, controversies and uncertainties will continue to challenge clinicians and patients. On topics where evidence is not clear-cut, judgement may be coloured by pre-existing practises and the structure of the health service in each country, so one has to be aware of the pitfalls of transferring recommendations to one's own practise.

    Full Text Available Introduction: Liver is involved with the synthesis of carrier proteins and metabolism of various hormones and liver diseases may, therefore, be associated with various endocrine disturbances. This study was conducted to assess thyroid and gonadal function in subjects with acute hepatitis (AH, chronic liver disease (CLD, and those who had undergone liver transplantation (LT. Materials and Methods: Patients with AH, CLD with Child-Pugh stage A (CLD-1 and Child-Pugh stage B or C (CLD-2, and LT seen at our tertiary level hospital were assessed clinically, biochemically, and for thyroid and gonadal functions besides 25 healthy controls. Results: Thyroid dysfunction and hypogonadism were present in 14 (16% and 24 (28% patients with liver diseases respectively. Among thyroid dysfunction, the commonest was sick euthyroid syndrome six (7%, followed by subclinical hypothyroidism in three patients (3.5%, subclinical hyperthyroidism and thyrotoxicosis in two patients each (2.3% and overt hypothyroidism in one patient. Among patients with LT and AH groups, the only abnormality was significantly lower total T3 compared with healthy controls. The CLD2 group had significantly lower levels of all thyroid hormones compared with controls and CLD1 group. Hypogonadism was commonest in patients with CLD-2 (14; 50% followed by LT (3; 33%, CLD-1 (4; 20%, and AH (3; 14%. Hypogonadism was predicted by older age, lower levels of serum albumin, total cholesterol, and triglycerides and higher levels of plasma glucose, serum bilirubin, aspartate transaminases, and international normalized ratio. Gonadal functions showed recovery following LT. Conclusions: Thyroid dysfunction and hypogonadism form an important part of the spectrum of acute and CLD, and patients with LT. Deterioration of synthetic functions of liver disease predicts presence of hypogonadism.

Thyroid disruption may be caused by a variety of mechanisms, as different chemicals interfere with the hypothalamic......-pituitary-thyroid axis at different levels. Mechanisms of action may involve the sodium-iodide symporter, thyroid peroxidase enzyme, receptors for THs or TSH, transport proteins or cellular uptake mechanisms. The peripheral metabolism of the THs can be affected through effects on iodothyronine deiodinases or hepatic...... enzymes. Even small changes in thyroid homeostasis may adversely affect human health, and especially fetal neurological development may be vulnerable.

    The status of experimental studies of radiogenic thyroid cancer is appraised, and some older data are reinterpreted in the light of more recent findings. Problems of thyroid dosimetry, particularly the dosimetry of internal radioiodides, are discussed. The steps in radiation carcinogenesis during the acute phase, the latent phase, and the phase of tumor growth are discussed in terms of thyroid epithelial cell population changes. The roles of three cell populations (undamaged or completely repaired epithelial cells, oncogenically initiated cells, and terminally damaged but functionally competent cells) in neoplasia are described. Finally, the implications for man of these experimental results and conclusions are discussed. 89 refs., 4 figs

  17. Thyroid Allostasis–Adaptive Responses of Thyrotropic Feedback Control to Conditions of Strain, Stress, and Developmental Programming

    Directory of Open Access Journals (Sweden)

    Apostolos Chatzitomaris

    2017-07-01

    Full Text Available The hypothalamus–pituitary–thyroid feedback control is a dynamic, adaptive system. In situations of illness and deprivation of energy representing type 1 allostasis, the stress response operates to alter both its set point and peripheral transfer parameters. In contrast, type 2 allostatic load, typically effective in psychosocial stress, pregnancy, metabolic syndrome, and adaptation to cold, produces a nearly opposite phenotype of predictive plasticity. The non-thyroidal illness syndrome (NTIS or thyroid allostasis in critical illness, tumors, uremia, and starvation (TACITUS, commonly observed in hospitalized patients, displays a historically well-studied pattern of allostatic thyroid response. This is characterized by decreased total and free thyroid hormone concentrations and varying levels of thyroid-stimulating hormone (TSH ranging from decreased (in severe cases to normal or even elevated (mainly in the recovery phase TSH concentrations. An acute versus chronic stage (wasting syndrome of TACITUS can be discerned. The two types differ in molecular mechanisms and prognosis. The acute adaptation of thyroid hormone metabolism to critical illness may prove beneficial to the organism, whereas the far more complex molecular alterations associated with chronic illness frequently lead to allostatic overload. The latter is associated with poor outcome, independently of the underlying disease. Adaptive responses of thyroid homeostasis extend to alterations in thyroid hormone concentrations during fetal life, periods of weight gain or loss, thermoregulation, physical exercise, and psychiatric diseases. The various forms of thyroid allostasis pose serious problems in differential diagnosis of thyroid disease. This review article provides an overview of physiological mechanisms as well as major diagnostic and therapeutic implications of thyroid allostasis under a variety of developmental and straining conditions.

    Permanent hypoparathyroidism following thyroid surgery is rare. Its prevalence is reported to be below 1–2% if surgery is performed by experienced thyroid surgeons. Parathyroid identification and preservation in situ with good vascular supply is the mainstay of safe thyroid surgery. However, if the parathyroid glands are damaged, autotransplantation should be undertaken to preserve their function. Parathyroid transplantation can be considered in three distinct modes of application: (I) fresh ...

    The goiter prevalence in iodine-deficient regions is up to 25%-54%. The most frequent disease in these endemic areas is non-toxic goiter, which is, however, oftentimes connected with autonomously functioning thyroid tissue leading to borderline or overt hyperthyroidism. Other thyroid diseases like cancer, thyroiditis and hypothyroidism play only a miner role in a thyroid clinic, while cases of Graves' disease may be observed more frequently. The most cost-effective tools to evaluate thyroid patients are the hand, ear and mouth of the thyroid clinician. The differential diagnosis of thyroid disorders may be evaluated by a battery of diagnostic tools like in-vitro tests and high performance imaging modalities. Once the diagnosis is established, the appropriate therapeutic procedures (drugs, radioiodine, surgery) have to be chosen. This review should be considered as a guideline for the diagnosis and treatment of thyroid diseases. In addition, special problems concerning elderly patients and pregnant women are discussed, including the differential diagnosis of thyroid diseases. (orig.)

    Full Text Available Postsurgical hypothyroidism and its incidence has not been fully investigated. In this study, the incidence of hypothyroidism and its possible risk factors at Shariati Hospital was assessed. One hundred and two patients with benign thyroid diseases, who had undergone thyroidectomy, were investigated with regards to thyroid function profile during period of one year after the operation every three months with post-operative sample as the baseline. Hypothyroidism was developed in 36 patients (35.2% on average 5 ± 3.2 months after surgery. Factors such as increased age, operation type, histopathologic type, underlying disease, lymphocytic infiltration and use of levothyroxine before surgery were associated with the increased incidence of hypothyroidism. It seems that use of indicators such as Graves' disease and lymphocytic infiltration in pathologic specimens should be helpful in projecting the potential occurrence of hypothyroidism in patients undergoing thyroidectomy.

    Chronic suppurative otitis media (CSOM) is still a significant health problem in developing countries. Therefore, it was pertinent to determine the local Malawian microbiology in order to guide adequate treatment, avoid complications, and provide records for future reference. The study sought to determine the CSOM-causing microorganisms at Queen Elizabeth Central Hospital in Blantyre, Malawi, and establish their relationship signs and symptoms, and with the demographic pattern of the study. This was a hospital-based cross-sectional descriptive study carried out at the ENT outpatient clinic and the Microbiology Department of Queen Elizabeth Central Hospital.The sample comprised 104 patients with unilateral or bilateral active CSOM, who met the inclusion criteria. All patients were evaluated through a detailed history and clinical examination. Pus samples from draining ears were collected by aspiration with a sterile pipette. The specimens were immediately sent for microbiological analysis. Data were analyzed using SPSS.version 20. The study found that Proteus mirabilis, Pseudomonas aeruginosa, and Staphylococcus aureus were the most prevalent aerobic bacteria, while Bacteroides spp. and Peptostreptococcus spp. were the commonest anaerobic bacteria causing CSOM. These CSOM-causing microorganisms were predominant among males aged 18 years and below. Some CSOM-causing microorganisms were-significantly more so than the others-characteristically associated with each of the following clinical features: quantity of pus drainage, mode of onset, otalgia, hearing loss, location of tympanic membrane perforation, and mucosal appearance.

    Full Text Available BACKGROUND Chronic Suppurative Otitis Media (CSOM is one of the most common diseases of younger age in middle class population of the developing countries. Loss of hearing due to CSOM has a role in learning and intelligence of the students. There are multiple factors, which affect the tympanic membrane repair, mastoidectomy is one. MATERIALS AND METHODS This study at Era’s Lucknow Medical College and Hospital was planned to assess the effect of cortical mastoidectomy in safe type CSOM. For that, 120 patients were taken who were divided in two groups of 60 each. One group was subjected to tympanoplasty type 1 and other to cortical mastoidectomy and type 1 tympanoplasty. RESULTS After six months of follow up, it was found that graft rejection was 13 in group 1 compared to 12 in group2 and cortical mastoidectomy has almost no effect on graft acceptance and hearing gain in pure tone audiometry. CONCLUSION This study was planned to find the effect of cortical mastoidectomy in tympanoplasty type 1 in safe type CSOM. Two groups of 60 patients were taken. In one group, only tympanoplasty type 1 while in other cortical mastoidectomy along with tympanoplasty type 1 was done. After 6 months of follow up, no statistically significant difference was found in the graft rejection and hearing gain between the two groups.

    Objective: To diagnose common organisms causing Chronic Suppurative Otitis Media (CSOM) and their in vitro sensitivity. Methodology: This descriptive study was carried out at Ear Nose and Throat (ENT) Department, Combined Military Hospital (CMH) Multan from July 2014 to June 2015. A total of 140 patients with active CSOM were included in this study. Ear swabs were collected from the discharging ear and sent for aerobic cultures only. Antibiotic sensitivity testing was done with standard antibiotic discs using Kirby Bauer disk diffusion method. Results: Pathogens were isolated in all except 13 ears. Pseudomonas aeruginosa was the most common organism isolated alone in 76 ears and in combination with other micro-organisms in 18 ears, followed by staphylococcus aureus in 23 and MRSA in four ears. Mixed organisms were found in 20 patients. Antibiotic sensitivity of Pseudomonas aeruginosa showed that 100% isolates were sensitive to imipenem and meropenem while Staphylococcus aureus was 100% sensitive to Chloramphenicol. Conclusion: Pseudomonas aeruginosa and staphylococcus aureus were commonest organism isolated in CSOM. Similar studies should periodically be conducted in various regions to have a current knowledge of the offending organisms and their sensitivity patterns against various antibiotics before commencing treatment of CSOM.

    Hydrogen peroxide, generated by thyroid oxidase enzymes, is a crucial substrate for the thyroid peroxidase (TPO)-catalysed biosynthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3) in the thyroid gland. It is believed that the $H_2O_2$ generation is a limiting step in thyroid hormone synthesis. Therefore, the control of hydrogen peroxide concentration is one of the possible mechanisms for the inhibition of thyroid hormone biosynthesis. The inhibition of thyroid hormone synthe...

    2017-12-01

    Full Text Available Endocrine disruptor compounds are exogenous agents able to interfere with a gland function, exerting their action across different functional passages, from the synthesis to the metabolism and binding to receptors of the hormone produced. Several issues, such as different levels and time of exposure and different action across different ages as well as gender, make the study of endocrine disruptors still a challenge. The thyroid is very sensitive to the action of disruptors, and considering the importance of a correct thyroid function for physical and cognitive functioning, addressing this topic should be considered a priority. In this review, we examined the most recent studies, many of them concentrating on maternal and child exposure, conducted to assess the impact of industrial chemicals which showed an influence on thyroid function. So far, the number of studies conducted on that topic is not sufficient to provide solid conclusions and lead to homogeneous guidelines. The lack of uniformity is certainly due to differences in areas and populations examined, the different conditions of exposures and the remarkable inter-subject variability. Nonetheless, the European Commission for Health and Food Safety is implementing recommendations to ensure that substances identified as endocrine disruptors will be withdrawn from the market.

    1976-01-01

    It is now generally accepted that an association exists between external radiation administered to the head, neck, and upper thorax of infants, children, and adolescents and the subsequent development of neoplastic changes in the thyroid gland. Until recent years, external radiation was frequently administered to shrink an enlarged thymus or for the treatment of tonsillitis, adenoiditis, hearing loss, hemangioma, acne, tinea capitis, and other conditions. During the course of these treatments, the thyroid gland was exposed to scatter radiation. The use of external radiation therapy was then accepted practice, and its value was attested by many. Concern about the adverse effects was not initially appreciated, primarily because of the long periods of time between the radiation and the recognition of changes in the thyroid. The availability and effectiveness of other therapeutic measures and the growing concern about the delayed effects of radiation therapy when administered to the young for relatively benign conditions has, in recent years, largely eliminated use of this form of therapy, except in a few unusual conditions

    Kinetics of thyroid hormones were outlined, and recent progress in metabolism of these hormones was also described. Recently, not only T 4 and T 3 but also rT 3 , 3,3'-T 2 , 3',5'-T 2 , and 3,5-T 2 can be measured by RIA. To clarify metabolic pathways of these hormones, metabolic clearance rate and production rate of these hormones were calculated. As single-compartment analysis was insufficient to clarify disappearance curves of thyroid hormones in blood such as T 3 and T 2 of which metabolic speed was so fast, multi-compartment analysis or non-compartment analysis were also performed. Thyroid hormones seemed to be measured more precisely by constant infusion method. At the first step of T 4 metabolism, T 3 was formed by 5'-monodeiodination of T 4 , and rT 3 was formed by 5-monodeiodination of T 4 . As metabolic pathways of T 3 and rT 3 , conversion of them to 3,3'-T 2 or to 3',5'-T 2 and 3,5-T 2 was supposed. This subject will be an interesting research theme in future. (Tsunoda, M.)

    Full Text Available A thyroid mass, most often a non toxic colloid goiter or occasionally an adenoma, is not an unusual finding below the level of the thoracic inlet.1 In 1992 Creswell and Wells estimated that these tumors comprise 5.8% of all mediastinal lesions.1 There is no standard definition for thyroid glands extending below the thoracic inlet, but such masses descend from their original cervical location for more than 2 or 3 cm below the thoracic inlet, and are not truly primary tumors of the mediastinum. They preserve the connection between the thoracic and cervical portion and receive their blood supply from the neck.2,3 In 1940, the seminal report of Wakeley and Mulvany divided intrathoracic thyroid masses into 3 types; (1”Small substernal extension” of a mainly cervical mass, (2 “Partial” intrathoracic, in which the major portion of the mass is situated within the thorax, and (3”Complete” in which all of the mass lies within the thoracic cavity.

The patient is informed about the lifelong necessity of taking a thyroid hormones daily before breakfast. This hormone must be given orally and its bioligical effect is identical with that of the tyhroid hormone secreted by the healthy thyroid gland. 2. The daily dosage of thyroid hormones may be assessed on the basis of the following parameters: a) the patient's clinical euthyroidism, b) suppression of thyrotropic activity, c) unrestricted tolerance of the preparation. 3. The in vitro parameters associated with optimal medication should be within the following ranges: Thyroxine value (TT4 or FT4): above the normal range, triiodothyronine value (TT3 or FT3): within the upper normal range and thyrotropin value (TSH 'ultrasensitive' or TRH-test): suppressed.

  19. Breaking Tolerance to Thyroid Antigens: Changing Concepts in Thyroid Autoimmunity

    Science.gov (United States)

    Rapoport, Basil

    2014-01-01

    Thyroid autoimmunity involves loss of tolerance to thyroid proteins in genetically susceptible individuals in association with environmental factors. In central tolerance, intrathymic autoantigen presentation deletes immature T cells with high affinity for autoantigen-derived peptides. Regulatory T cells provide an alternative mechanism to silence autoimmune T cells in the periphery. The TSH receptor (TSHR), thyroid peroxidase (TPO), and thyroglobulin (Tg) have unusual properties (“immunogenicity”) that contribute to breaking tolerance, including size, abundance, membrane association, glycosylation, and polymorphisms. Insight into loss of tolerance to thyroid proteins comes from spontaneous and induced animal models: 1) intrathymic expression controls self-tolerance to the TSHR, not TPO or Tg; 2) regulatory T cells are not involved in TSHR self-tolerance and instead control the balance between Graves' disease and thyroiditis; 3) breaking TSHR tolerance involves contributions from major histocompatibility complex molecules (humans and induced mouse models), TSHR polymorphism(s) (humans), and alternative splicing (mice); 4) loss of tolerance to Tg before TPO indicates that greater Tg immunogenicity vs TPO dominates central tolerance expectations; 5) tolerance is induced by thyroid autoantigen administration before autoimmunity is established; 6) interferon-α therapy for hepatitis C infection enhances thyroid autoimmunity in patients with intact immunity; Graves' disease developing after T-cell depletion reflects reconstitution autoimmunity; and 7) most environmental factors (including excess iodine) “reveal,” but do not induce, thyroid autoimmunity. Micro-organisms likely exert their effects via bystander stimulation. Finally, no single mechanism explains the loss of tolerance to thyroid proteins. The goal of inducing self-tolerance to prevent autoimmune thyroid disease will require accurate prediction of at-risk individuals together with an antigen

    To determine whether the sonographic appearance of thyroid cancer differs in patients with and without Hashimoto thyroiditis. Patients with histologically proven thyroid cancer who had thyroid peroxidase (TPO) antibodies measured and sonography performed preoperatively were included. We evaluated each nodule for size, echogenicity, composition, margins, halo, and vascularity and evaluated the background heterogeneity of the gland. There were 162 thyroid cancers in 145 patients. Forty-two patients (29.0%) had Hashimoto thyroiditis with positive TPO antibodies, and 103 patients (71.0%) had negative TPO antibodies. The background echogenicity was more often heterogeneous in TPO antibody-positive patients compared to those who had negative TPO antibodies (57.1% versus 26.2%; P= .0005). Comparing cancers in TPO antibody-positive to TPO antibody-negative patients, there was no significant difference in the size, echogenicity, composition, margins, halo presence, calcification presence and type, or vascularity of the cancerous nodule (P > .05). Among TPO antibody-positive patients, comparing thyroid cancerous nodules in patients with heterogeneous glands to those with homogeneous glands, there was no significant difference in any sonographic characteristic except the margin of the nodule, which was more often irregular or poorly defined in heterogeneous glands and more often smooth in homogeneous glands (PHashimoto thyroiditis. Among patients with Hashimoto thyroiditis and thyroid cancer, the sonographic appearance of the cancerous nodule is similar, except that cancerous nodule margins are more likely to be irregular or poorly defined when the gland is heterogeneous. © 2015 by the American Institute of Ultrasound in Medicine.

    Plasma fibronectin concentrations up to 85 mg/100 ml were found in hyperthyroid patients. There was a significant correlation between free thyroxine index and plasma fibronectin values. Hypothyroid patients had low to normal fibronectin concentrations. Parallel decreases of thyroid hormones and plasma fibronectin concentrations were noted during treatment with thiamazole. A direct effect of thyroid hormones on fibronectin synthesis seems probable.

    During the functional ontogenesis of the thyroid gland an increasing number of transcription factors play fundamental roles in thyroid-cell differentiation, maintenance of the differentiated state, and thyroid-cell proliferation. The early growth and development of the fetal thyroid appears to be generally independent of thyroid-stimulating hormone (TSH). TSH and thyroxine (T4) levels increase from the 12th week of gestation until delivery, whereas triiodothyronine (T3) levels remain relatively low. At birth, a cold-stimulated short-lived TSH surge is observed, followed by a TSH decrease until day 3 or 4 of life by T4 feedback inhibition. Disorders of thyroid gland development and/or function are relatively common, affecting approximately one newborn infant in 2000-4000. The most prevalent disease, congenital hypothyroidism, is frequently caused by genetic defects of transcription factors involved in the development of the thyroid or pituitary gland. A major cause of congenital hyperthyroidism is the transplacental passage of stimulating thyrotropin antibodies from the mother to the fetus. Hypothyroxinaemia or hypotriiodthyroninaemia is frequently observed in preterm infants with or without severe non-thyroidal illness. Whereas congenital hypo- and hyperthyroidism may be treated successfully with T4 or thyrostatic drugs, there is still insufficient evidence on whether the use of T4 for treatment of the latter condition results in changes in neonatal morbidity or reductions in neurodevelopmental impairment.

    Full text: An important problem in nuclear endocrinology is 'blocking' of thyroid gland, which necessitates postpone of the investigation, adverse clinical effect of stopping medications and a delay of making diagnosis. The aim of the study was to introduce and to determine the clinical value of the scintigraphy with 99mTc-MIBI in patients (Pts) with 'blocked thyroid'. In 365 Pts (aged 38-75 years), indicated for a thyroid scintigraphy after proper preparation, an investigation was performed with 74 MBq 99mTc-pertechnetate, 20 min. p.i. In 14 of them (3.8%), the thyroid was 'blocked' and additional scintigraphy was done with 370-555 MBq 99mTc-MIBI, 15 and 120 min.p.i. It was estimated that in all Pts there was a visualization of thyroid. In 1 of them, a large 'hot' nodule was visualized in the early and late image. Later on a differentiated thyroid carcinoma was proved histologically. In the rest of the patients 'cold' nodules with different size were visualized, eventually as a result of cysts. As a conclusion we consider, that a scintigraphy with 99mTc-MIBI is a useful tool in Pts with 'blocked' thyroid. In addition an evaluation of the thyroid nodule could be done and therefore- a recommendation for therapy

    Over half a century, treatment of thyroid autonomy with an oral dose of iodine-131 has proven to be effective. The optimum management strategy for the patient is, however, still a matter of debate. The article provides an overview of the pathogenesis of functional autonomy and its clinical relevance. According to the guidelines on both sides of the Atlantic, radioiodine treatment is considered the most comfortable and economical approach to the treatment of the toxic nodular goitre. Some differences in the preparation procedures in the guidelines of the American and the German Society of Nuclear Medicine are discussed with respect to therapy results and the subtypes of thyroid autonomy. The results of studies are summarised concerning changes in thyroid function and thyroid volume after a course of radioiodine treatment. Therapy-related risks, such as immunogenic hypothyroidism or thyroid cancer, are discussed. 131 I treatment of functional autonomy and hyperthyroidism is considered an effective and safe procedure.

    Full Text Available Thyroid hemiagenesis is a very rare anomaly. We herein report a case with right thyroid lobe agenesis, which was incidentally found during the assessment of primary hyperparathyroidism. A 42-year-old male presenting with urinary lithiasis was suspected of having primary hyperparathyroidism, and had elevated levels of both serum calcium and intact parathyroid hormone. Both computed tomography and ultrasonography demonstrated the absence of right thyroid lobe and a mass of 1 cm in diameter at the left lower pole of the thyroid. The patient underwent lower left parathyroidectomy, which confirmed the right thyroid hemiagenesis, as well as the absence of both upper and lower right parathyroid glands. The resected left lower parathyroid gland was pathologically diagnosed as adenoma. The postoperative course was favourable and he was discharged on the 2nd day after surgery, without complications.

    To estimate the prevalence of World Health Organization-defined chronic suppurative otitis media (CSOM) and mild hearing impairment in a population representative sample of school-entry age children in rural Malawi. A secondary objective was to explore factors associated with CSOM in this population. We performed a community-based cross-sectional study of children aged 4-6 years in Chikhwawa District, Southern Malawi, utilising a village-level cluster design. Participants underwent a structured clinical assessment, including video-otoscopy and screening audiometry. Diagnoses were made remotely by two otolaryngologists who independently reviewed clinical data and images collected in the field. Hearing impairment was classified as failure to hear a pure tone of 25dB or greater at 1, 2 or 4kHz. We recruited 281 children across 10 clusters. The prevalence estimates of CSOM, unilateral hearing impairment and bilateral hearing impairment were 5.4% (95%CI 2.2-8.6), 24.5% (95%CI 16.3-30.0), and 12.5% (95%CI 6.2-16.9) respectively. Middle ear disease was seen in 46.9% of children with hearing impairment. A trend towards increased risk of CSOM was observed with sleeping in a house with >2 other children. We found a high burden of middle ear disease and preventable hearing impairment in our sample of school-entry age children in rural Malawi. There are important public health implications of these findings as CSOM and hearing impairment can affect educational outcomes, and may impact subsequent development. The identification and management of middle ear disease and hearing impairment represent major unmet needs in this population.

    Full Text Available Background: Chronic suppurative otitis media (CSOM is one of the leading causes of preventable disabling hearing impairment (DHI in developing countries. Early detection and management complements advances made in other survival programs, improves work capacity, and enhances learning opportunities for school children. We aimed to determine the prevalence of CSOM and associated DHI among school children aged six to 16 years in Socotra Island, Yemen. Methods: We conducted a cross-sectional community-based survey, from 20 April 2011 to 20 June 2011. The study procedures involved completing a questionnaire, an otoscopic ear examination, an audiometric test of hearing, and tuning fork tests for the type of DHI. Results: A total of 686 children were interviewed and examined for CSOM and associated DHI of CSOM cases. The prevalence of CSOM was 7.4%, (95% CI 5.5–9.4. CSOM status was significantly associated with DHI (p=0.001, but no significant associations were found between demographic characteristics and CSOM status. Logistic regression identified four significant independent contributing factors: history of ear discharge in the last 12 months (odds ratio (OR 7.8, 95% CI 3.9–15.6; swimming in local pools (OR 6.0, 95% CI 1.4–25.4; recurrent respiratory tract infection more than three times per year (OR 5.3, 95% CI 2.5–11.0; and overcrowding with more than three families per house (OR 4.4, 95% CI 1.7–11.5. . Conclusion: The burden of CSOM in the children studied indicates a high level of DHI in these communities within Yemen. A history of ear discharge, swimming in local pools, recurrent respiratory infections, and overcrowded housing were the strongest predictors for CSOM. There is a need for better ear care and screening programs for early detection and management of this disease.

    Otitis media (OM) has been observed at elevated prevalence rates in Greenlandic children. OM associated hearing loss (HL) may compromise the children's linguistic skills, social development and educational achievements. We investigated the prevalence of chronic suppurative otitis media (CSOM), otitis media with effusion (OME) and tympanic membrane sequelae of OM, and compared the corresponding hearing thresholds. In 2010 we examined a cohort of 223 Greenlandic children aged 4-10 years by video otoscopy, tympanometry and tested hearing thresholds for the low-frequencies: 500, 1000 and 2000Hz and the high-frequencies: 4000 and 6000Hz. HL was categorized according to the worst hearing ear and was compared within the groups: CSOM, OME, tympanic membrane sequelae of OM and normal. Of 207 children, 5.8% had CSOM, 13.9% had OME and 55.6% had tympanic membrane sequelae of OM. The median pure tone average in low-frequencies/high-frequencies were: CSOM: 34.2/31.3dB, OME: 23.3/22.5dB, Sequelae of OM: 13.3/15dB and normal ears: 11.7/12.5dB. We found a significant difference (pchildren a HL>15dB in any frequency was found, while 6.5% suffered from a bilateral low-frequency HL>25dB. The severity of OM significantly corresponded to increased HL. The burden of CSOM and HL remains high in young Greenlandic children. Aggressive treatment with antibiotics, improved hearing rehabilitation, sound field amplification in classrooms and otosurgical capacity should be further promoted in Greenland.

    Studies have showed that lead was associated with human health. However, the effects of lead on thyroid functions are inconsistent, and studies based on Chinese population are fragmentary. To evaluate the correlation between lead and thyroid functions of Chinese with different thyroid diseases, we conducted a hospital-based study. Ninety-six papillary thyroid carcinoma (PTC), 10 nodular goiter (NG), and 7 thyroid adenoma (TA) patients were recruited from the First Affiliated Hospital of Wenzhou Medical University, China. Serum triiodothyronine (T3), free triiodothyronine (FT3), free thyroxin (FT4), and thyroid stimulating hormone (TSH) were evaluated with chemiluminescent microparticle immunoassay. Serum lead was assessed with ICP-MASS. Partial correlation was used to explore the correlations of serum lead and thyroid diseases. Compared to PTC, the level of lead was significantly higher in TA, and lower in NG (p lead was negatively correlated with TSH (r s  =  - 0.27, p lead at quartile4 (r s  = 0.61, p lead and FT3 or FT4 in any group. The results suggested that lead might have different etiological roles in these three thyroid diseases.

    Thyroid storm, an endocrine emergency, remains a diagnostic and therapeutic challenge. It is recognized to develop as a result of several factors, including infection, surgery, acute illness, and rarely, trauma. Recognition of thyroid storm in a trauma patient is difficult because the emergency physician usually focuses on managing more obvious injuries. We present a case of trauma-related thyroid storm and review the previous literature on posttraumatic thyroid storm to delineate risk factors of the disease. The case occurred in a 32-year-old man after a motorcycle accident. Careful investigation of patient history and risk factors of trauma-related thyroid storms and utilization of the scoring system may facilitate early diagnosis. Traumatically induced thyroid storm usually responds to medical treatment developed for hyperthyroidism. Surgical intervention may be needed for patients who failed medical treatment or those with direct thyroid gland injuries. The outcome is usually fair under appropriate management. We present a case of trauma-related thyroid storm to illustrate the diagnostic and therapeutic approach with a summary of the previous literature. Emergency physicians should be aware of the clinical presentation and risk factors of patients with trauma-related thyroid storm to reduce the rate of misdiagnosis and prevent catastrophic outcomes.

    Normal thyroid physiology and pathophysiology with reference to non-thyroidal illness (NTI) is reviewed including specific disease states and drugs and their effect on thyroid function tests. The diagnostic utility of two new highly sensitive thyrotrophin (TSH) assays as screening tests for thyroid dysfunction are evaluated and compared with conventional thyroid function assays. A group of 40 patients with NTI was studied. This group was compared to a group of normal controls and a group of thyrotoxic patients. Conventional thyroid function tests yielded many values outside the reference range in the NTI group. The general pattern that emerged was decreased total triiodothyronine levels in 70% of NTI patients, normal to low thyroxine values, increased mean free thyroxine values (dialysis), low mean values for the free thyroxine index and varying results for newer commercial assays for free thyroxine according to methodology. The TSH response to intravenous thyroliberin (TRH) was found to be blunted compared to controls. Basal TSH levels were measured with two ultasensitive TSH assays. The immunoradiometric assays yielded fewer values outside the reference range in the NTI group than conventional thyroid function tests. This assay yielded undetectable basal TSH levels in all thyrotoxic patients and could reliably separate thyrotoxic patients from the NTI group. Basal TSH levels with ultrasensitive TSH assays correlated well with the TSH response to TRH (TSH) and could obviate the need for TRH tests. Ultrasensitive TSH assays are promising first line screening tests in NTI. 120 refs., 13 figs., 7 tabs

    Full Text Available La tormenta tiroidea es una de las situaciones más críticas entre las emergencias endocrinas y tiene una significativa mortalidad. La etiología más común de tirotoxicosis es la enfermedad de Graves y el factor precipitante que predomina es la infección. Clínicamente se caracteriza por la disfunción de varios sistemas (termorregulador, nervioso central, gastrointestinal y cardiovascular, con niveles de hormonas tiroideas libres o totales por encima de los valores normales. El tratamiento debe tener un enfoque multidisciplinario, e incluye medidas de soporte en unidades de cuidados intensivos, normalización de la temperatura corporal, reducción de la producción y liberación de hormonas tiroideas, con antitiroideos de síntesis y yodo respectivamente, bloqueo de los efectos periféricos mediante la administración de beta-bloqueadores, y corrección del factor desencadenante. Una vez que el paciente se encuentra estable es necesario planificar una terapia definitiva que impida la recurrencia futura de la crisis tirotóxica.The thyroid storm is one of the most critical situations in the endocrine emergencies and exhibits a significant mortality rate. The most common etiology of thyrotoxicosis is Graves' disease and the predominant precipitating factor is infection. The clinical characteristics are dysfunction of several systems (heat-regulator, central nervous, gastrointestinal and cardiovascular, and levels of total or free thyroid hormones that exceed the normal values. The treatment must be multidisciplinary and include support measures in intensive care units, normalization of body temperature, reduction of the production and the release of thyroid hormones by using synthesis and iodine anti-thyroid products respectively, blockade of the peripheral effects through administration of Beta-blockers and correction of the unleashing factor. Once the patients are stabilized, it is necessary to plan the final therapy that will prevent the

    Computerized axial tomography scans permit proper distinction between primary and secondary goitres and help in preoperative planning. Advances in anesthetic techniques and the use of small-caliber endotracheal tubes facilitate proper perioperative management, even for patients with significant respiratory compression symptoms. A tracheotomy is rarely necessary. Aggressive surgical therapy for retrosternal goitres avoids life-threatening situations and results in minimal morbidity and practically zero mortality when performed by a surgeon experienced in managing such patients. Radioactive iodine therapy is used in the treatment of metastases of differentiated thyroid carcinoma if they concentrate 131 I

    Full Text Available In the month of Ramadan, patients with thyroid diseases, most of the time, do not need treatment adjustments and can fast safely without any health hazards. Patients with hypothyroidism taking thyroxine can take their tablets on an empty stomach at bedtime instead of half an hour before Sehr. Patients with hyperthyroidism, on methimazole/carbimazole can continue their dose in once or twice daily regimes, while those on propylthiouracil need to be switched. Hyperthyroid patients with severe symptoms should start treatment immediately and can avoid fast for few days after a consultation with their religious scholar.

    Full Text Available Administration of a precise amount of activity in thyroid gland radioiodine (¹³¹I therapy is of prime importance. Several methods for this purpose have been suggested and used over many years. In this paper, a method for required ¹³¹I activity calculation for each case has been proposed. Major factors affecting ¹³¹I calculation such as gland volume, integral dose, and prescription index have been described. Using the method, ¹³¹I activity or any other radioisotope activity required for a certain case can be determined with a good estimate.

    Full Text Available Although traumatic thyroid gland rupture or hemorrhage is usually seen in goitrous glands, injuries of the normal thyroid gland after neck trauma have rarely been described in the literature. We describe a 44-year-old man who presented with thyroid emphysema and subcutaneous emphysema (SCE that occurred after penetrating neck trauma. CT images showed complete resolution of thyroid emphysema and subcutaneous emphysema at follow-up examination. Neck injuries can be life threatening. After penetrating neck traumas, physicians should consider subtle esophageal or tracheal laceration. Thyroid emphysema can occur as the result of penetrating neck trauma. The mechanism of emphysema of the thyroid parenchyma can be explained by the thyroid gland’s presence in a single visceral compartment that encompasses the larynx, trachea and thyroid gland. We describe an unusual case of thyroid emphysema of a normal thyroid gland following a penetrating neck injury.

  15. High-frequency conductive hearing loss as a diagnostic test for incomplete ossicular discontinuity in non-cholesteatomatous chronic suppurative otitis media.

    Directory of Open Access Journals (Sweden)

    Krishnamurti M A Sarmento

    Full Text Available Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD, partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL has been considered a hallmark of incomplete ossicular discontinuity. This study aims to evaluate the use of HfCHL as a preoperative predictor of IOD in patients with non-cholesteatomatous chronic suppurative otitis media. The HfCHL test was defined as the preoperative air-bone gap (ABG at 4 kHz minus the average of the ABG at 0.25 and 0.5 kHz. The test was applied in 328 patients before surgery and compared to intraoperative findings as the gold standard. At surgery, 201 (61.3% patients had an intact ossicular chain, 44 (13.4% had a complete ossicular discontinuity, and 83 (25.3% exhibited an IOD. The best cutoff level was calculated as 10 dB. The HfCHL test to diagnose IOD had a sensitivity of 83% and a specificity of 92% with a post-test probability of 78% and a likelihood ratio of 10.2. We concluded that the HfCHL test is highly effective in predicting IOD in patients with non-cholesteatomatous chronic suppurative otitis media and that it should be used routinely as a screening test prior to surgery.

    Full Text Available The thyroid cancer is a rare oncological entity, representing no more than 1% of all human malignant neoplasms. Recently, it has been demonstrated a sharp increase in incidence of differentiated thyroid carcinoma, equally occurring in both sexes. So far, multiple genetic alterations have been identified in differentiated thyroid carcinoma, leading to investigate the clinical utility of genetic studies. In particular, molecular genetic approaches searching for gene mutations in the material collected by fine needle ago-biopsy may have a particular utility in small nodules and in those specimens with an indeterminate cytology. The expansion of knowledge about genetic mutations occurring in different thyroid tumors has characterized recent years, allowing the identification of a correlation between specific mutations and phenotypic characteristics of thyroid cancers, essential for their prognosis. This review will briefly report on the histological features and the new entity represented by thyroid microcarcinoma and will focus on both environmental and genetic aspects associated with the occurrence of thyroid cancer.

    The International Atomic Energy Agency (AIEA) is carrying out the ARCAL VIII Program 'Thiroid Hormone Readioimmunoassay'. The Immunoassay Laboratory of INCIENSA is in charge of this program, with the participation of four National Hospital System laboratories, which carried out Thyroxine (T4). Triodothyroxine (T3) and Thyroid Stimulating Hormone (TSH) assays with NETRIA Reagents (North East Thames Region Immunoassay Unit). The variability was shown to be between 9-20 per cent for T4, 12-22 per cent for TSH and 22-36 per cent for T3. The study also evaluated the quality of a tracer (T3-l125 and T4 l125) produced at INCIENSA. In this case the intrassay variability was 8,4 per cent for T3 and 6,8 per cent for T4 in 32 determinations evaluated during 6 months. It was concluded that the T4 and TSH tests but not the T3 test are valid and reproducible when NETRIA Ragents are used. The tracer made at INCIENSA can be used up to 6 weeks after the radioiodination with l125. A successful thyroid-related hormones quality control was defined in Costa Rica by taking advantage of the support of a prestigious international agency, the IAEA. (author). 13 refs, 4 figs

  18. Thyroid Hormone Deiodinases and Cancer

    Antonio eBianco

    2012-06-01

    Full Text Available Deiodinases constitute a group of thioredoxin-containing selenoenzymes that play an important function in thyroid hormone homeostasis and control of thyroid hormone action. There are three known deiodinases: D1 and D2 activate the pro-hormone thyroxine (T4 to T3, the most active form of thyroid hormone, while D3 inactivates thyroid hormone and terminates T3 action. A number of studies indicate that deiodinase expression is altered in several types of cancers, suggesting that (i they may represent a useful cancer marker and/or (ii could play a role in modulating cell proliferation - in different settings thyroid hormone modulates cell proliferation. For example, although D2 is minimally expressed in human and rodent skeletal muscle, its expression level in rhabdomyosarcoma (RMS-13 cells is 3-4 fold higher. In basal cell carcinoma (BCC cells, sonic hedgehog (Shh-induced cell proliferation is accompanied by induction of D3 and inactivation of D2. Interestingly a 5-fold reduction in the growth of BCC in nude mice was observed if D3 expression was knocked down. A decrease in D1 activity has been described in renal clear cell carcinoma, primary liver cancer, lung cancer, and some pituitary tumors, while in breast cancer cells and tissue there is an increase in D1 activity. Furthermore D1 mRNA and activity were found to be decreased in papillary thyroid cancer while D1 and D2 activities were significantly higher in follicular thyroid cancer tissue, in follicular adenoma and in anaplastic thyroid cancer. It is conceivable that understanding how deiodinase dysregulation in tumor cells affect thyroid hormone signaling and possibly interfere with tumor progression could lead to new antineoplastic approaches.

    This report documents 3 pediatric papillary thyroid carcinoma cases with associated Hashimoto thyroiditis. In all 3 cases, hypoechoic nodules accompanied by multiple echogenic spots were noted on sonography of the thyroid. Hashimoto thyroiditis was suspected on the basis of positive thyroid autoantibody test results and pathologic examinations of thyroidectomy specimens, which revealed chronic thyroiditis with lymphocytic infiltration as the background of papillary thyroid carcinoma development. The potential for papillary carcinoma development warrants close follow-up, and meticulous sonographic examinations must be performed in children with Hashimoto thyroiditis. © 2014 by the American Institute of Ultrasound in Medicine.

  1. Thyroid Hormones, Oxidative Stress, and Inflammation

    2016-01-01

    Full Text Available Inflammation and oxidative stress (OS are closely related processes, as well exemplified in obesity and cardiovascular diseases. OS is also related to hormonal derangement in a reciprocal way. Among the various hormonal influences that operate on the antioxidant balance, thyroid hormones play particularly important roles, since both hyperthyroidism and hypothyroidism have been shown to be associated with OS in animals and humans. In this context, the nonthyroidal illness syndrome (NTIS that typically manifests as reduced conversion of thyroxine (T4 to triiodothyronine (T3 in different acute and chronic systemic conditions is still a debated topic. The pathophysiological mechanisms of this syndrome are reviewed, together with the roles of deiodinases, the enzymes responsible for the conversion of T4 to T3, in both physiological and pathological situations. The presence of OS indexes in NTIS supports the hypothesis that it represents a condition of hypothyroidism at the tissue level and not only an adaptive mechanism to diseases.

    This study investigated the association of serum B-lymphocyte activating factor (BAFF) levels with autoimmune thyroid disease (AITD) in a Chinese population. We enrolled 221 patients with AITD [170 patients with Graves' disease (GD), 51 patients with Hashimoto's thyroiditis (HT)], and 124 healthy controls. Serum BAFF levels, thyroid function and thyroid autoantibody (TAb) levels, including of thyroid-stimulating hormone receptor antibody (TSHRAb), anti-thyroid peroxidase antibody (Anti-TPO Ab), and antithyroglobulin antibody (ATA), were measured at baseline. Serum BAFF levels were higher in the GD, HT, and AITD groups than in the control group. Significant correlations were observed between BAFF and TSHRAb levels (r=0.238, p=0.018), between BAFF and Anti-TPO Ab levels (p=0.038), and between BAFF and ATA titers (p=0.025) in women but not in men. In addition, serum BAFF levels were significantly associated with free thyroxine (r=0.430, p=0.004) and TSHRAb (r=0.495, p=0.001) levels in women with active GD but not in those with inactive GD. Serum BAFF levels are increased in GD, HT, and AITD. The correlation between serum BAFF and TAb levels exhibits a dimorphic pattern, particularly in active GD. Copyright © 2016 Elsevier B.V.

    2014-01-01

    Background: Hashimoto's thyroiditis (HT) has been found to coexist with differentiated thyroid cancer (DTC) in surgical specimens, but an association between the two conditions has been discounted by the medical literature. Therefore, we performed this study to determine any potential relationship between HT and the risk of developing DTC. Methods: We collected data for thyrotropin (TSH), thyroxine (T4), thyroid peroxidase antibody (TPO-Ab) titers, surgical pathology, and weight-based levothyroxine (LT4) replacement dose for patients who were referred for thyroid surgery. Patients with HT at final pathology were studied further. To estimate thyroid function, patients with preoperative hypothyroid HT (Hypo-HT) were divided into three equal groups based on their LT4 replacement: LT4-Low (1.43 μg/kg). A group of preoperatively euthyroid (Euth-HT) patients but with HT by pathology was also studied. All subjects were also grouped based on their TPO-Ab titer in TPO-high (titer >1:1000) or TPO-low/negative (titer thyroid glands (LT4-Low) but not in fully hypothyroid HT (LT4-Mid and LT4-High). High TPO-Ab titers appear to protect against DTC in patients with HT. PMID:24708347

    2012-02-01

    OBJECTIVE: The Tubercle of Zuckerkandl (TZ), which is the remant of the lateral thyroid process, is an important anatomic structure that serves as a reliable landmark for the recurrent laryngeal nerve in thyroid surgery. Furthermore, removal of the TZ is critical for the adequate performance of a total thyroidectomy. However, there is little mention of the TZ in surgical textbooks or papers. METHODS: Prospective observational study of 138 consecutive thyroid surgeries. The presence of the TZ, its size, and relationship to the recurrent laryngeal nerve, were recorded. RESULTS: A total of 211 thyroid lobes were included in the study. The TZ was identified in 61.1% of all thyroid lobes. The median size was 8 mm (range = 3-40 mm). A TZ was more commonly identified on the right (69.6%) than on the left side (53.2%) (P = .02). The recurrent laryngeal nerve was found deep to the TZ in 98.4% of cases. CONCLUSIONS: A TZ is present in the majority of thyroid lobes. Awareness of the TZ is critical in performing an adequate total thyroidectomy, and is very useful as a landmark for the recurrent laryngeal nerve.

    Magnetic resonance imaging was performed in 38 diffuse goiters, including 30 chronic thyroiditis and 8 Basedow disease. MR findings were analyzed as to degree of swelling, margin, internal structures including homogeneity and low intensity bands. With regard to signal intensity, thyroid-muscle-signal intensity ratios on T1 and T2-weighted images were measured in 19 normal thyroid glands, 30 chronic thyroiditis and 8 Basedow disease. Additionally thyroid-muscle-signal intensity ratios were compared between 19 hypothyroid glands and 11 euthyroid glands in chronic thyroiditis. Chronic thyroiditis tended to show lobulated margins, inhomogeneous intensity, and low intensity bands connecting with vessels or not. Basedow disease tended to display smooth margins, inhomogeneous intensity and low intensity bands connecting with vessels. Thyroid-muscle-signal intensity ratios of Basedow disease and chronic thyroiditis were significantly higher than those of normal thyroid gland at all sequences. In chronic thyroiditis thyroid-muscle-signal intensity ratios of euthyroid glands were significantly higher than those of hypothyroid glands. MR imaging could reflect pathologic features of diffuse goiters. Moreover, MR imaging is potentially contributory to speculate about thyroid function and degree of serious condition in diffuse thyroid disorders. (author)

    Normally, differentiated thyroid carcinoma(DTC) is a disease of good prognosis, but about 30% of the tumors are dedifferentiate, which are inaccessible to standard therapeutic procedures such as 'operation, 131 I therapy and thyroid hormone'. Both internal and abroad experts are researching a new therapy of dedifferentiated thyroid carcinoma--gene therapy. Many of them utilize methods of it, but follow different strategies: (1) transduction of the thyroid sodium/iodide transporter gene to make tissues that do not accumulate iodide treatable by 131 I therapy; (2) strengthening of the anti-tumor immune response; (3) suicide gene therapy; (4) depression the generation of tumor cells; (5) gene therapy of anti- vascularization.

    1999-01-01

    The biological behavior and hence the prognosis of thyroid cancer (TC) depends among other factors on the extent of spread of the disease outside the thyroid bed. This effect is controversial, especially for nodal metastasis of well differentiated thyroid carcinoma (WDC). Nodal metastasis at the time of initial diagnosis behaves differently depending on the histology, age of the patient, presence of extrathyroidal extension, and the sex of the individual. The type of the surgery, administration of 131 I and thyroxin suppression also to some extent influence the rate of recurrence and mortality. Experience has shown that it is not as innocuous as a small intrathyroidal tumor without any invasion outside the thyroid bed and due consideration should be accorded to the management strategies for handling patients with nodal metastasis

    The purpose of this study was to analyse the various patterns of calcification demonstrated in the anterior and lateral neck roentgenograms of 213 unselected patients with thyroid enlargement. The patterns of thyroid calcifications were correlated with clinical, surgical and histological findings. The results were as follows: 1. Of 213 cases of thyroid enlargement, 180 cases were benign and 168 cases were female. 2. The calcification rate was high in the chronic thyroid enlargement. 3. The incidence of calcification was 30.2% in the malignancy and 17.2% in the benign disease. There was no calcification in the Hashimoto's disease. 4. The nodular calcification was demonstrated in the both benign and malignant disease but curvilinear calcification was predominantly seen in benign disease.

    2017-01-01

    Permanent hypoparathyroidism following thyroid surgery is rare. Its prevalence is reported to be below 1–2% if surgery is performed by experienced thyroid surgeons. Parathyroid identification and preservation in situ with good vascular supply is the mainstay of safe thyroid surgery. However, if the parathyroid glands are damaged, autotransplantation should be undertaken to preserve their function. Parathyroid transplantation can be considered in three distinct modes of application: (I) fresh parathyroid tissue autotransplantation during thyroidectomy in order to reduce the risk of permanent hypoparathyroidism; (II) cryopreserved parathyroid tissue autotransplantation in patients with permanent hypoparathyroidism; (III) parathyroid allotransplantation in patients with permanent hypoparathyroidism when cryopreserved parathyroid tissue is not available for grafting. Nowadays, allotransplantation of cultured parathyroid cells without immunosuppression should be taken into consideration in selected patients as an alternative to calcium and vitamin D3 supplementation in management of permanent hypoparathyroidism. This paper is aimed to provide a review of current status of various parathyroid transplantation techniques in thyroid surgery. PMID:29142845

    Full Text Available Abstract Background Chronic suppurative otitis media (CSOM is a major health problem in developing countries causing hearing loss and life threatening complications. Early and effective treatment based on the knowledge of causative micro-organisms and predictors of outcome are crucial in preventing these associated complications. This study was conducted to determine the predictors of CSOM complications, treatment outcome and antimicrobial susceptibility of pathogens, thus providing essential evidence to formulate a policy for management of CSOM. Methods This was a prospective hospital based cross sectional study involving 301 patients attending Ear Nose and Throat (ENT clinics at Bugando Medical Centre (BMC between October 2013 and March 2014. A standardized data collection tool was used to collect demographics and clinical characteristics of patients with CSOM. Ear swabs were collected using sterile cotton swabs and transported to the laboratory for culture and antibiotic susceptibility testing. Results Out of 301 patients with CSOM; 187 (62.1 % had positive aerobic culture within 48 h of incubation. Disease complications and poor treatment outcome were observed in 114 (37.8 %, 95 % CI; 32.2–43.3 and 46 (15.3 %, 95 % CI; 11.2–19.3 respectively. On multivariate logistic regression analysis factors found independently to predict both disease complications and poor treatment outcome were otalgia, being infected by multi drug resistant bacteria and being HIV positive.

    Even though it is a rare event, most associations of thyroid carcinoma with subacute thyroiditis described in the literature are related to its granulomatous form (Quervain's thyroiditis). We present a patient with subacute lymphocytic thyroiditis (painless thyroiditis) and papillary thyroid cancer that was first suspected in an initial ultrasound evaluation. A 30-year old female patient who was referred to the emergency room due to hyperthyroidism symptoms was diagnosed with painless thyroiditis established by physical examination and laboratory findings. With the presence of a palpable painless thyroid nodule an ultrasound was prescribed and the images revealed a suspicious thyroid nodule, microcalcification focus in the heterogeneous thyroid parenquima and cervical lymphadenopathy. Fine needle aspiration biopsy was taken from this nodule; cytology was assessed for compatibility with papillary thyroid carcinoma. Postsurgical pathology evaluation showed a multicentric papillary carcinoma and lymphocytic infiltration. Subacute thyroiditis, regardless of type, may produce transitory ultrasound changes that obscure the coexistence of papillary carcinoma. Due to this, initial thyroid ultrasound evaluation should be delayed until clinical recovery. We recommended a thyroid ultrasound exam for initial evaluation of painless thyroiditis, particularly in patients with palpable thyroid nodule. Further cytological examination is recommended in cases presenting with suspect thyroid nodule and/or non-nodular hypoechoic (> 1 cm) or heterogeneous areas with microcalcification focus.

  15. Thyroid Dysfunction from Antineoplastic Agents

    Science.gov (United States)

    Larsen, P. Reed; Marqusee, Ellen

    2011-01-01

    Unlike cytotoxic agents that indiscriminately affect rapidly dividing cells, newer antineoplastic agents such as targeted therapies and immunotherapies are associated with thyroid dysfunction. These include tyrosine kinase inhibitors, bexarotene, radioiodine-based cancer therapies, denileukin diftitox, alemtuzumab, interferon-α, interleukin-2, ipilimumab, tremelimumab, thalidomide, and lenalidomide. Primary hypothyroidism is the most common side effect, although thyrotoxicosis and effects on thyroid-stimulating hormone secretion and thyroid hormone metabolism have also been described. Most agents cause thyroid dysfunction in 20%–50% of patients, although some have even higher rates. Despite this, physicians may overlook drug-induced thyroid dysfunction because of the complexity of the clinical picture in the cancer patient. Symptoms of hypothyroidism, such as fatigue, weakness, depression, memory loss, cold intolerance, and cardiovascular effects, may be incorrectly attributed to the primary disease or to the antineoplastic agent. Underdiagnosis of thyroid dysfunction can have important consequences for cancer patient management. At a minimum, the symptoms will adversely affect the patient’s quality of life. Alternatively, such symptoms can lead to dose reductions of potentially life-saving therapies. Hypothyroidism can also alter the kinetics and clearance of medications, which may lead to undesirable side effects. Thyrotoxicosis can be mistaken for sepsis or a nonendocrinologic drug side effect. In some patients, thyroid disease may indicate a higher likelihood of tumor response to the agent. Both hypothyroidism and thyrotoxicosis are easily diagnosed with inexpensive and specific tests. In many patients, particularly those with hypothyroidism, the treatment is straightforward. We therefore recommend routine testing for thyroid abnormalities in patients receiving these antineoplastic agents. PMID:22010182

    One of the main objectives of the procedures is to establish the likelihood of malignancy in the thyroid gland prior to surgery and detect metastases after surgery. Thyroid imaging is discussed in the context of (a) its role in the diagnosis of the primary disease (b) in the investigation of post-operative residual disease and (c) its role in the follow-up of patients after radioiodine therapy

    Full Text Available Phthalates are extensively used as plasticizers in a variety of daily-life products, resulting in widespread distribution in aquatic environments. However, limited information is available on the endocrine disrupting effects of phthalates in aquatic organisms. The aim of the present study was to examine whether exposure to mono-(2-ethylhexyl phthalate (MEHP, the hydrolytic metabolite of di-(2-ethylhexyl phthalate (DEHP disrupts thyroid endocrine system in fish. In this study, zebrafish (Danio rerio embryos were exposed to different concentrations of MEHP (1.6, 8, 40, and 200 μg/L from 2 h post-fertilization (hpf to 168 hpf. The whole-body content of thyroid hormone and transcription of genes involved in the hypothalamic-pituitary-thyroid (HPT axis were examined. Treatment with MEHP significantly decreased whole-body T4 contents and increased whole-body T3 contents, indicating thyroid endocrine disruption. The upregulation of genes related to thyroid hormone metabolism (Dio2 and UGT1ab might be responsible for decreased T4 contents. Elevated gene transcription of Dio1 was also observed in this study, which might assist to degrade increased T3 contents. Exposure to MEHP also significantly induced transcription of genes involved in thyroid development (Nkx2.1 and Pax8 and thyroid hormone synthesis (TSHβ, NIS and TG. However, the genes encoding proteins involved in TH transport (transthyretin, TTR was transcriptionally significantly down-regulated after exposure to MEHP. Overall, these results demonstrate that acute exposure to MEHP alters whole-body contents of thyroid hormones in zebrafish embryos/larvae and changes the transcription of genes involved in the HPT axis, thus exerting thyroid endocrine toxicity.

    Objective: To evaluate the prevalence of subclinical thyroid disease (SCTD) in local population visiting a hospital laboratory for thyroid function tests. Design: It was a hospital - based study carried in consecutive patients who reported for thyroid function tests in the hospital laboratory. Place and duration of study: The study was conducted in combined military Hospital, Quetta during June 1999 to September 2000. Subject and methods: Serum samples of 917 patients living in Quetta and its surrounding were analysed for thyroid stimulating hormone (TSH) free thyroxin (FT4), and total tri-iodothyronine (T3) concentration using chemiluminescence technique on hormone auto analyser (LIA-Mat - Sangtech Germany). Results: Out of 917 patients, 287 (23%) were found to be having SCTD while overt thyroid disease was found in 288 (31%) patients. Prevalence of sub-clinical hypothyroidism (SCO) and sub-clinical hyperthyroidism (sce) was found to be almost equal with a profound female preponderance in both the groups. SCO was more common in children (<12 years of age). Conclusion: Almost every fourth patient reporting for thyroid function tests was diagnosed as having SCTD - a disease entity that is still not well known and that poses diagnostic and management problems for the pathologists and clinicians.

    Introduction  It is essential to determine the quality of life among individuals with chronic suppurative otitis media (CSOM). However, there is limited literature on health-related quality of life measurements in Kannada-speaking individuals with CSOM. Objectives  The present study attempted to translate and validate Chronic Suppurative Otitis Media Questionnaire-12 (COMQ-12) and Chronic Otitis Media Outcome Test-15 (COMOT-15) in Kannada. Method  The English questionnaires were translated and back-translated, and they were later verified for content validity. The developed questionnaires were then administered to 100 individuals with CSOM for further validation. Results  The results of the study showed that the translated questionnaires have good internal consistency for measuring quality of life among individuals with CSOM. The study also showed that Kannada-speaking individuals with CSOM show significant impairment in their health-related quality of life measures. Conclusions  The impairments were more related to ear symptoms and psychological issues. However, test-retest reliability of the developed questionnaire and its further validation are essential. Thus, these questionnaires attempt to understand the problems of the individuals with CSOM from the patients' perspective and help clinicians provide the appropriate management.

    Radioiodine therapy is used in the treatment of patients with differentiated thyroid cancer both to ablate residual thyroid tissue after initial surgery and to treat residual, recurrent, or metastatic cancer. In most institutions, therapy remains based on empirically determined, fixed amounts of radioiodine that do not account for individual differences in the mass of tissue to be treated and in radioiodine kinetics. Over the last 25 years, we have developed and refined techniques based on pre-therapy, diagnostic quantitative radiation dosimetry and imaging with 131I that permit individualized treatment which balances the success of the treatment and the risk of serious acute adverse effects on the bone marrow and lungs. In this manuscript we discuss patient selection and preparation for radioiodine therapy and outline in detail methods for performing quantitative dosimetry studies. Guidelines for the application of these results to the treatment of individual patients are presented.

    Employees of Sanofi-Aventis Deutschland GmbH underwent thyroid screening in 2006 to assess new data about the prevalence of irregular sonomorphological pattern, elevated thyroid peroxidase antibodies (TPO AB) and thyroid function in an unselected adult German population. The examination included 700 unselected employees. Blood samples were analyzed for serum TSH and TPO AB, and ultrasound of the thyroid was performed. In 40.7% of the participants (n = 285) an irregular sonomorphological pattern was detected: goiter in 13.7%, nodules in 35.6%, nodular goiter in 8.6% and a hypoechogenic pattern of the thyroid gland in 20.4%. Serum TSH was increased in 3.9% and decreased in 0.6%. Elevated TPO AB values were observed in 13%. Only 1.4% (n = 10) showed elevated TPO AB combined with a TSH increase. Sonomorphological abnormalities were associated with increased TPO AB in 7.1%. Elevated TPO AB was observed significantly more often in combination with sonomorphological pathology (54.9%) than without (45.1%) (p = 0.003). Sonomorphological disorders are still very common in Germany and our results are comparable with previous screening examinations. Elevated TPO AB correlated significantly with the sonomorphological pattern of nodules and goiter. This may reflect an improved iodine supply or a hypertrophic stage of autoimmune thyroiditis in some cases.

    To diagnosis and understand the pathophysiologic status of thyroid disease, not only hormonal measurements but also thyroid scan is believed to have a unique role. Especially in the cases of the change of the thyroid function by thyroiditis, it is emphasized that thyroid scan can be helpful in differential diagnosis, Discordant results of thyroid hormone levels and thyroid scan are found in transient hyperthyroidism, or in transient hypothyroidism. We analysed and reevaluated thyroid scan to look at the importance of thyroid scan. The results are summarised as follows: 1) 80%. of hyperthyroid patients had hyperthyroidism increased RAIU with even density, they are compatible with Graves' disease. 2) 2.1% of hyperthyroid patients had normal or decreased RAIU, which are classified as high iodine turn over genuine hyperthyroidism. 3) 8.5% of hyperthyroid patients had markedly decreased RAIU at both 2 hour and 24 hour, whose pathologic processes are suggested to be heterogenous namely subacute thyroiditis, postpartum thyroiditis, Hashimoto's thyroiditis, and pamless thyroiditis. 4) 45% of hypothyroid patients had increased 24 hr RAIU, 30% of hypothyroid patients were normal, 25%, decreased. In conclusion, thyroid scan should be reevaluated its useful role to asses the pathophysiologic status of thyroid disease. Especially in cases of transient thyrotoxicosis, thyroid scan is essential to diagnose and follow up the disease process.

    Thyroid cancer is the most common malignant tumor of the endocrine system and the incidence has been increasing in recent years. In a great part of the differentiated carcinomas, thyrocytes are capable of uptaking iodide. In these cases, the main therapeutic approach includes thyroidectomy followed by ablative therapy with radioiodine. However, in part of the patients, the capacity to concentrate iodide is lost due to down-regulation of the sodium-iodide symporter (NIS), the protein responsible for transporting iodide into the thyrocytes. Thus, therapy with radioiodide becomes ineffective, limiting therapeutic options and reducing the life expectancy of the patient. Excessive ingestion of some flavonoids has been associated with thyroid dysfunction and goiter. Nevertheless, studies have shown that some flavonoids can be beneficial for thyroid cancer, by reducing cell proliferation and increasing cell death, besides increasing NIS mRNA levels and iodide uptake. Recent data show that the flavonoids apingenin and rutin are capable of increasing NIS function and expression in vivo. Herein we review literature data regarding the effect of flavonoids on thyroid cancer, besides the effect of these compounds on the expression and function of the sodium-iodide symporter. We will also discuss the possibility of using flavonoids as adjuvants for therapy of thyroid cancer.

    Radioactive iodine is released at every atomic-bomb testings and nuclear plants accidents and radioactive iodine is taken up by thyroid glands (internal radiation). In addition to the internal radiation, radioactive fallout causes the external radiation and thyroid glands are known to be sensitive to the external radiation. Furthermore, patients with radiation-induced thyroid disease can survive for a long time regardless of the treatment. The survey of thyroid diseases, therefore, is very sensitive and reliable ways to investigate the effects of radiation caused by atomic bomb explosion, testing and various types of nuclear plants' accidents. Our group from Nagasaki University was asked to investigate the thyroid diseases and jointed to the Sasakawa Project. In order to investigate the effects of radiation on thyroid disease, it is essential 1) to make a correct diagnosis in each subject, 2) to calculate a correct radiation dose in each subject and finally, 3) to find out the correlation between the radiation dose and thyroid diseases including age-, sex- and area-matched controls. We have established 5 centers (1 in Russia, 2 in Belarus, 2 in Ukraine) and supplied the most valuable ultrasonography instruments, commercial kits for the determination of serum free T 4 and TSH level and for the autoantibodies, instrument for urinary iodine measurements, syringers, tubes, refrigerators, etc. We visit each center often and asked people at centers to come to Japan for training. Protocol of investigation is essentially the same as that in Nagasaki, and we are planning to investigate more than 50,000 children within 5 years. We are hoping to show a definite conclusion in the near future. Recent articles are also discussed. (author)

    Thyroid-related emergencies are caused by overt dysfunction of the gland which are so severe that require admission to intensive care units (ICU) frequently. Nonetheless, in the ICU setting, it is crucial to differentiate patients with non-thyroidal illness and alterations in thyroid function tests from those with intrinsic thyroid disease. This review presents and discusses the main etiopathogenetical and clinical aspects of hypothyroid coma (HC) and thyrotoxic storm (TS), including therapeutic strategy flow-charts. Furthermore, a special chapter is dedicated to the approach to massive goiter, which represents a surgical thyroid emergency. We searched the electronic MEDLINE database on September 2013. Data Selection and Data Extraction: Reviews, original articles, and case reports on "myxedematous coma," "HC," "thyroid storm," "TS," "massive goiter," "huge goiter," "prevalence," "etiology," "diagnosis," "therapy," and "prognosis" were selected. Severe excess or defect of thyroid hormone is rare conditions, which jeopardize the life of patients in most cases. Both HC and TS are triggered by precipitating factors, which occur in patients with severe hypothyroidism or thyrotoxicosis, respectively. The pillars of HC therapy are high-dose l-thyroxine and/or tri-iodothyroinine; i.v. glucocorticoids; treatment of hydro-electrolyte imbalance (mainly, hyponatraemia); treatment of hypothermia; often, endotracheal intubation and assisted mechanic ventilation are needed. Therapy of TS is based on beta-blockers, thyrostatics, and i.v. glucocorticoids; eventually, high-dose of iodide compounds or lithium carbonate may be of benefit. Surgery represents the gold standard treatment in patients with euthyroid massive nodular goiter, although new techniques - e.g., percutaneous laser ablation - are helpful in subjects at high surgical risk or refusing operation.

This retrospective study included 1310 thyroid nodules of 1254 euthyroid asymptomatic patients who underwent US-guided fine-needle aspiration biopsy between November 2012 and August 2013. Nodule size and clinical risk factors- such as patient age, gender, first-degree family history of thyroid cancer, multiplicity on US and serum thyroid stimulating hormone (TSH) levels - were considered together with US features to compare benign and malignant nodules. Multiple logistic regression analysis was performed to assess the risk of thyroid malignancy according to clinical and US characteristics. Although all of the clinical factors and US findings were significantly different between patients with benign and malignant nodules, a solitary lesion on US (p = 0.041–0.043), US features and male gender (p < 0.001) were significant independent risk factors for thyroid malignancy in a multivariate analysis. Patient age, a first-degree family history of thyroid cancer and high normal serum TSH levels did not independently significantly increase the risk of thyroid cancer. However, multicollinearity existed between US assessment and patient age, first-degree family history of thyroid cancer and serum TSH values. Ultrasonography findings should be the primary criterion used to decide the management of euthyroid asymptomatic patients with thyroid nodules. The concept of first-degree family history as a risk factor for thyroid malignancy should be further studied in asymptomatic patients

    2017-01-01

    Autoimmune diseases of the thyroid gland are considered to be the most frequent cause of thyroid gland disorders. Autoimmune thyroid diseases consist of two subgroups: autoimmune thyroiditis (AIT) and Graves' disease. The AIT is the most common human autoimmune disease. Infiltration of the thyroid gland with cytotoxic T‑cells can lead to an initial thyrotoxicosis und during the course to hypothyroidism due to destruction of the thyroid gland. Substitution with Levothyroxine is indicated for manifest hypothyroidism and subclinical hypothyroidism with increased thyroid antibodies with the intention of normalizing the serum thyroid stimulating hormone (TSH). Graves' disease is characterized by the appearance of stimulating TSH receptor antibodies leading to hyperthyroidism. Endocrine ophthalmopathy may also occur. Ablative therapy with radioiodine therapy or thyroidectomy is administered to patients with Graves' disease without remission after at least 1 year of antithyroid drug therapy.

    Full Text Available Alcohol is one of the commonest illicit psychoactive substances consumed globally and is the world′s third largest risk factor for disease and disability. It has been reported to have multiple effects on the hypothalamo-pituitary-thyroid axis and the functioning of the thyroid gland. It has been reported to cause direct suppression of thyroid function by cellular toxicity, and indirect suppression by blunting thyrotropin-releasing hormone response. It causes a decrease of peripheral thyroid hormones during chronic use and in withdrawal. Alcohol use may also confer some protective effect against thyroid nodularity, goiter, and thyroid cancer. This article presents a review of the clinically relevant effects of alcohol on the functioning of the thyroid gland and also discusses the effect of medication used in treatment of alcohol dependence on thyroid function.

    Full Text Available Physiological changes during gestation are important to be aware of in measurement and interpretation of thyroid function tests in women with autoimmune thyroid diseases. Thyroid autoimmune activity is decreasing in pregnancy. Measurement of serum TSH is the first-line screening variable for thyroid dysfunction also in pregnancy. However, using serum TSH for control of treatment of maternal thyroid autoimmunity infers a risk for compromised foetal development. Peripheral thyroid hormone values are highly different among laboratories, and there is a need for laboratory-specific gestational age-related reference ranges. Equally important, the intraindividual variability of the thyroid hormone measurements is much narrower than the interindividual variation (reflecting the reference interval. The best laboratory assessment of thyroid function is a free thyroid hormone estimate combined with TSH. Measurement of antithyroperoxidase and/or TSH receptor antibodies adds to the differential diagnosis of autoimmune and nonautoimmune thyroid diseases.

    Objective: To study the relation between change of thyroid tissues and thyroid auto- antibody after thyroid arterial embolization in the treatment of hyperthyroidism caused by Graves' disease with observation on changes of histopathology and thyroid auto-antibody in 3 years after thyroid arterial embolization, and to understand the foundation of the therapeutic action after arterial embolization. Methods: 1. Thirty-eight patients with Graves' disease treated by transcathter arterial embolization had been tested serum TT3, TT4, FT3, FT4, rT3, TSH, TGAb, TPOAb, TRAb and followed up with color Doppler ultrasound respectively at different periods (before arterial embolization and 7 day, 6 month, 3 year after arterial embolization). 2. 23 patients underwent needle aspiration biopsy of the thyroid gland. Results: Volume of thyroid gland instantly dwindled in size after thyroid arterial embolization or within a few days. The changes of histopathology mainly showed acute ischemic necrosis 7 days after thyroid arterial embolization and followed by fibrous hyperplasia mesenchymal proliferation and follicular atrophy occurring 6 months and 3 years afterward. TGAb, TPOAb at the 3rd year after thyroid arterial embolization were higher than those before the thyriod arterial embolization. FT3, FT4, TRAb at 6 month after thyroid arterial embolization were lower than those of the 3 years. Conclusion: Maladjustment of immunity in GD patients would be improved through the treatment of thyroid arterial embolization, synchronously with the promotion in histopathology. The outcomings of the shrinkage of thyroid tissue, decrease of thyroxin secretion and improvement of immunity provide a combination therapy for GD. (authors)

    The activity of the hypothalamic-pituitary-thyroid (HPT) axis is rapidly adjusted by energy balance alterations. Glucocorticoids can interfere with this activity, although the timing of this interaction is unknown. In vitro studies indicate that, albeit incubation with either glucocorticoid receptor (GR) agonists or protein kinase A (PKA) activators enhances pro-thyrotrophin-releasing hormone (pro-TRH) transcription, co-incubation with both stimuli reduces this enhancement. In the present study, we used primary cultures of hypothalamic cells to test whether the order of these stimuli alters the cross-talk. We observed that a simultaneous or 1-h prior (but not later) activation of GR is necessary to inhibit the stimulatory effect of PKA activation on pro-TRH expression. We tested these in vitro results in the context of a physiological stimulus on the HPT axis in adult male rats. Cold exposure for 1 h enhanced pro-TRH mRNA expression in neurones of the hypophysiotrophic and rostral subdivisions of the paraventricular nucleus (PVN) of the hypothalamus, thyrotrophin (TSH) serum levels and deiodinase 2 (D2) activity in brown adipose tissue (BAT). An i.p. injection of corticosterone stimulated pro-TRH expression in the PVN of rats kept at ambient temperature, more pronouncedly in hypophysiotrophic neurones that no longer responded to cold exposure. In corticosterone-pretreated rats, the cold-induced increase in pro-TRH expression was detected only in the rostral PVN. Corticosterone blunted the increase in serum TSH levels and D2 activity in BAT produced by cold in vehicle-injected animals. Thus, increased serum corticosterone levels rapidly restrain cold stress-induced activation of TRH hypophysiotrophic neurones, which may contribute to changing energy expenditure. Interestingly, TRH neurones of the rostral PVN responded to both corticosterone and cold exposure with an amplified expression of pro-TRH mRNA, suggesting that these neurones integrate stress and temperature

    It is known that thyroid hormone is an important regulator of cancer development and metastasis. What is more, changes across the genome, as well as alternative splicing, may affect the activity of the thyroid hormone receptors. Mechanism of action of the thyroid hormone is different in every cancer; therefore in this review thyroid hormone and its receptor are presented as a regulator of renal cell carcinoma.

    Dual ectopic lingual and sublingual thyroid gland is an extraordinarily rare condition. We present 1 patient with subclinical hypothyroidism. The clinical examination revealed that the thyroid gland was not palpable in its usual cervical location, whereas ultrasonography confirmed an empty thyroid bed without any ectopic thyroid tissue in the rest of the neck. The final diagnosis of dual ectopic lingual and sublingual thyroid was established by ultrasound examination through the mouth floor and confirmed by scintigraphy and CT thereafter.

    The chronic autoimmune thyroiditis are heterogeneous entities by the functional, lesional and evolutive point of view. Ethiopathogenic factors involved in chronic autoimmune thyroiditis are genetical factors, combines with environmental factors, hormonal factors, infectious factors etc. The exact role of smoking on the autoimmune mechanism is unclear, but smoking is known to have an antithyroid effect. Our study tries to estimate the influence of smoking on serum levels of antithyroid peroxidase antibodies and antithyroglobulin antibodies, in a group of patients with various clinical forms of chronic autoimmune thyroiditis. We studied a group consists of 310 patients with chronic autoimmune thyroiditis, hospitalised in the Endocrinology Department of Constanta County Hospital, between January 2006 - December 2009. We detected serum values of antithyroidperoxidase antibodies and antithyroglobulin antibodies of our patients. We also followed the age, sex and presence of smoking in our study group. For statistical processing of the data we use Student's t-test. In our study group 24.28% of patients were smokers. Serum levels of antithyroid peroxidase antibodies were significantly increased (p < 0.001) in the smokers patients, compared with the nonsmokers patients. Serum levels of antithyroglobulin antibodies were significantly increased (p < 0.01) in smokers patients, compared with those who were nonsmokers. Smoking increased the serum levels of antithyroid antibodies in patients with chronic autoimmune thyroiditis.

    The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cytology. We excluded 65 cases because of preoperative diagnosis of thyroid cancer, and 68 because of nonincidental cancer within the index nodule. Among the remaining 580 cases, there were 43 cases (7.4%) of incidental thyroid cancers. Incidental thyroid cancers were significantly associated with moderate/severe lymphocytic thyroiditis (relative risk = 2.5; p = .03). Sixteen of 56 patients with moderate/severe lymphocytic thyroiditis had Graves' disease, none of whom had incidental thyroid cancer. The risk of incidental thyroid cancer associated with moderate/severe lymphocytic thyroiditis was significantly higher in non-Graves' than patients with Graves' disease (p = .05). The risk of incidental thyroid cancer is significantly increased in patients with moderate/severe lymphocytic thyroiditis. Moderate/severe lymphocytic thyroiditis associated with Graves' disease seems to have a lower risk of incidental thyroid cancer. © 2016 Wiley Periodicals, Inc.

    Epidemiological studies have shown an increased incidence of thyroid tumors after external irradiation during childhood. These studies have shown a long latency and have pointed out risk factors, related either to the subject (young age, female sex) or to the radiation (dose, fractionation, protection). Irradiation by Iodine 131 in adulthood does not seen to increase the risk of thyroid tumor but in childhood data are too scarce to allow any conclusion. Similarly, the risks following low radiation doses and/or protected radiation exposure are still matter of debate. (author). 41 refs., 5 tabs., 1 fig.

  1. Neurological complications in thyroid surgery: a surgical point of view on laryngeal nerves.

    Directory of Open Access Journals (Sweden)

    EMANUELA eVARALDO

    2014-07-01

    Full Text Available The cervical branches of the vagus nerve that are pertinent to endocrine surgery are the superior and the inferior laryngeal nerves: their anatomical course in the neck places them at risk during thyroid surgery. The external branch of the superior laryngeal nerve (EB is at risk during thyroid surgery because of its close anatomical relationship with the superior thyroid vessels and the superior thyroid pole region. The rate of EB injury (which leads to the paralysis of the cricothyroid muscle varies from 0 to 58%. The identification of the EB during surgery helps avoiding both an accidental transection and an excessive stretching. When the nerve is not identified,the ligation of superior thyroid artery branches close to the thyroid gland is suggested, as well as the abstention from an indiscriminate use of energy-based devices that might damage it. The inferior laryngeal nerve (RLN runs in the tracheoesophageal groove toward the larynx, close to the posterior aspect of the thyroid. It is the main motor nerve of the intrinsic laryngeal muscles, and also provides sensory innervation to the larynx. Its injury finally causes the paralysis of the omolateral vocal cord and various sensory alterations: the symptoms range from mild to severe hoarseness, to acute airway obstruction and swallowing impairment. Permanent lesions of the RNL occur from 0.3 to 7% of cases, according to different factors. The surgeon must be aware of the possible anatomical variations of the nerve which should be actively searched for and identified. Visual control and gentle dissection of RLN are imperative. The use of intraoperative nerve monitoring has been safely applied but, at the moment, its impact in the incidence of RLN injuries has not been clarified. In conclusion, despite a thorough surgical technique and the use of intraoperative neuromonitoring, the incidence of neurological complications after thyroid surgery cannot be suppressed, but should be maintained in a

    Thyrotoxic disease can be difficult to recognize in patients with resistance to thyroid hormone (RTH) because the clinical symptoms of thyrotoxicosis cannot be observed, and thyrotropin (TSH) may not be suppressed because of hormone resistance. Painless thyroiditis is a relatively common cause of thyrotoxicosis, but its occurrence in RTH has not been reported. We assessed the thyroid profile in a patient with RTH and episodes of thyrotoxicosis who experienced repeated painless thyroiditis. A 44-year-old Japanese woman with RTH, which was confirmed by the presence of a P453A mutation in the thyroid hormone receptor β (TRβ) gene, showed a slight elevation of the basal levels of thyroid hormones, which indicated that her pituitary RTH was mild. She experienced a slight exacerbation of hyperthyroxinemia concomitant with TSH suppression. A diagnosis of painless thyroiditis was made because of the absence of TSH receptor antibodies, low Tc-99m pertechnetate uptake by the thyroid gland, and transient suppression followed by a slight elevation of TSH following the elevation of thyroid hormones. The patient's complaints of general malaise and occasional palpitations did not change throughout the course of painless thyroiditis. Three years later, painless thyroiditis occurred again without any deterioration of the clinical manifestations. Mild pituitary RTH can be overcome by slight exacerbation of hyperthyroxinemia during mild thyrotoxicosis. When pituitary resistance is severe and TSH is not suppressed, thyrotoxicosis may be overlooked.

    A 66-year-old woman, who was diagnosed with iritis, visited our hospital due to general malaise. A blood analysis revealed hypercalcemia. Computed tomography revealed mediastinal and hilar lymph node hyperplasia. Moreover, 67 Gallium scintigraphy demonstrated strong accumulation in the lesions, suggesting sarcoidosis. A core needle biopsy (CNB) of the hypoechoic areas of the thyroid was performed because the patient refused to undergo a bronchoscopic examination. The scattering of slightly acidophilic epithelioid cell granulomas was observed in the pathological examination of the biopsy specimen. Based on this finding, the patient was diagnosed with sarcoidosis. Although sarcoidosis rarely involves the thyroid gland, in the present case, thyroid CNB was an alternative diagnostic method that allowed a pathological diagnosis to be obtained.

    Medullary thyroid carcinoma is a biologically distinct form of thyroid cancer and accounts for 5-10% of all thyroid neoplasms. Twenty percent of MTC can occur in a familial setting either by itself or as part of the multiple endocrine neoplasm syndromes. A disciplined approach is necessary in the work-up of these patients to rule out coexistent endocrine tumors (pheochromocytomas and parathyroid). Cacitonin is a sensitive tumor marker secreted by MTC that is of prognostic value and important in the follow-up of patients. Surgery is the mainstay of treatment with a total thyroidectomy and centre compartment clearance being the minimum for patients without cervical adenopathy. Radiotherapy has a limited role and is only indicated as a palliative measure in patients with advanced/metastatic disease not amenable to surgery

    The principle sources of iodine overload, amiodarone and radiologic contrast media, are frequently used in modern medicine. The thyroid gland exerts a protective effect against iodine excess by suppressing iodine internalization into the thyrocyte and iodine organification, the Wolff-Chaikoff effect. Insufficiency of this effect or lack of escape from it leads to hypo- or hyperthyroidism respectively. Amiodarone induced thyrotoxicosis is a complex condition marked by two different pathophysiological mechanisms with different treatments. Thyroid metabolism changes after exposure to radiologic contrast media are frequent, but they rarely need to be treated. High risk individuals need to be identifed in order to delay the exam or to monitor thyroid function or apply prophylactic measures in selected cases.

    Amiodarone is a benzofuran derivative that contains up to 40% of iodine. Amiodarone is used for treatment and prevention of life threatening supraventricular and ventricular tachyarrhythmias. The effects on thyroid gland vary from abnormalities in thyroid function tests to overt amiodarone induced hypothyroidism (AIH) and thyrotoxicosis (AIT). Patients with AIH are treated with L-thyroxine and may continue treatment with amiodarone. Two different forms of AIT have to be distinguished: amiodarone induced hyperthyroidism (AIT I) and thyroiditis (AIT II). AIT I is treated with antithyroid drugs, while total thyroidectomy and iodine-131 are used for definitive treatment. AIT II is treated with glucocorticoids. Patients with AIT have to stop treatment with amiodarone. Dronedarone is a less potent antiarrhythmic agent with structural and pharmacological properties similar to amiodarone. Dronedarone is devoid of iodine with fewer adverse effects and therefore it may be used in high risk patients for development of AIT or AIH.

    Several recent advances in our knowledge of thyroid physiology have broad application to the diagnosis and management of thyroid disorders. For in the thyroid, more than other end-ocrine organs, pathophysiology can be translated directly into the diagnosis and management of thyroid disease. Graves' disease is a syndrome including goiter with hyperthyroidism, exophthalmos and dermatopathy. The pathogenesis of Graves' disease is not yet clearly identified, but various autoantibodies to the thyroid gland and immunapathalogic studied indicate that autoimmune processes are involved in the pathogenesis of the disease. The diagnosis and management of Graves' disease are largely dependent on radionuclide technique as radioimmunoassay, radioactive iodine therapy and so on. Several laboratory tests are also developed to determine the remission of this disease including TRH stimulation test, T 3 , suppression test and detection of thyroid stimulating immunoglobulins. Autoimmune thyroiditis is almost certainly a primary immunologic disease and the incidence tends to increase recently, mainly due to the application of biopsy technique is thyroid diseases. Thyroid nodules have been a great challenge to physicians because of the possibility of malignancy. But recently, cytologic examination of thyroid aspirate provides a very simple and also reliable diagnostic method in patients with thyroid nodules. In 163 patients with thyroid nodules, only 19.3% was revealed to be malignant. Therefore cytologic examination of thyroid aspirate and thyroid biopsy should be included in the diagnosis of nodular patients prior to surgical intervention. In this paper, a comprehensive review is presented on the pathogenesis, clinical features, laboratory findings and therapeutic modalities of various thyroid diseases on the basis of over 80 researches performed during the past 20 years at radioisotope clinic, Seoul National University Hospital.

    To determine the frequency of thyroid dysfunction in infertile women referred for thyroid evaluation. Age matched infertile (n=140 each) and fertile women (n=152 each) referred to CENUM for thyroid evaluation were investigated for incidence of hyperthyroidism (TSH 20 IU/L). Serum free T4 (FT4), free T3 (FT3) and antithyroid peroxidase antibody (TPO-Ab) was determined by radioimmunoassay (RIA) and TSH by immunoradiometric assay (IRMA). Most of the infertile women (89.3%), like control women (93.4%), were euthyroid. The difference of overall thyroid dysfunction was not statistically significant in infertile and control women (10.7% vs. 7.9%; p=0.395). The same was true for incidence of hyperthyroidism (4.3% vs. 5.3%; p=0.701) as well as hypothyroidism (6.4% vs. 2.6%; p=0.104). In infertile women, the incidence of hypothyroidism (6.4%) was slightly higher as compared to hyperthyroidism (4.3%). In euthyroid women of both groups, mean FT4, FT3 and TSH levels were significantly higher (p 2.5 mIU/L compared to fertile women (31.2% vs. 15.6%; p 20 IU/L) than control women (7.2% vs. 1.4%; p<0.05). Increased incidence of high normal TSH and raised TPO-Ab titer indicate relatively more frequent occurrence of compensated thyroid function in infertile women than normal women of reproductive age. This necessitates considering them a subgroup of women in which all aspects of pituitary-thyroid axis should be thoroughly investigated than merely TSH testing. (author)

    Límanová, Zdeňka; Jiskra, Jan

    Cardiovascular system is essentially affected by thyroid hormones by way of their genomic and non-genomic effects. Untreated overt thyroid dysfunction is associated with higher cardiovascular risk. Although it has been studied more than 3 decades, in subclinical thyroid dysfunction the negative effect on cardiovascular system is much more controversial. Large meta-analyses within last 10 years have shown that subclinical hyperthyroidism is associated with higher cardiovascular risk than subclinical hypothyroidism. Conversely, in patients of age > 85 years subclinical hypothyroidism was linked with lower mortality. Therefore, subclinical hyperthyroidism should be rather treated in the elderly while subclinical hypothyroidism in the younger patients and the older may be just followed. An important problem on the border of endocrinology and cardiology is amiodarone thyroid dysfunction. Effective and safe treatment is preconditioned by distinguishing of type 1 and type 2 amiodarone induced hyperthyroidism. The type 1 should be treated with methimazol, therapeutic response is prolonged, according to recent knowledge immediate discontinuation of amiodarone is not routinely recommended and patient should be usually prepared to total thyroidectomy, or rather rarely 131I radioiodine ablation may be used if there is appropriate accumulation. In the type 2 there is a promt therapeutic response on glucocorticoids (within 1-2 weeks) with permanent remission or development of hypothyroidism. If it is not used for life-threatening arrhytmias, amiodarone may be discontinuated earlier (after several weeks). Amiodarone induced hypothyroidism is treated with levothyroxine without amiodarone interruption.Key words: amiodarone induced thyroid dysfunction - atrial fibrillation - cardiovascular risk - heart failure - hyperthyroidism - hypothyroidism - thyroid stimulating hormone.

    In order to investigate the usefulness of determining the serum concentrations of carcinoembryonic antigen (CEA) as a specific tumor marker in thyroid cancer, CEA serum levels were measured (enzymeimmunoassay, Abbott-Kit) repeatedly at the routine followup checks performed at various intervals after total thyroidectomy, in 65 patients with papillary, 82 with follicular, 25 with mixed type (papillary/follicular), 8 with anaplastic, and in 18 patients with medullary thyroid cancer. The postoperative observation period of these patients ranged from 2 to 36 months. Calcitonin serum levels were additionally determined in patients with medullary carcinoma (radioimmunoassay kit of Immuno-Nuclear Corp.). In the family of one patient with medullary carcinoma we also had an opportunity to investigate, within the framework of family screening (pentagastrin tests, etc.), the value of preoperative CEA determination. In the patients with ''non-medullary'' histological types of thyroid cancer, the maximum CEA serum concentration was 9.8 ng/ml. 6% of the patients with papillary, 9% of the patients with follicular, and 8% of those with mixed type thyroid cancer had serum levels above the upper limit of our normal range (5 ng/ml). All patients with anaplastic carcinoma had values below 3 ng/ml. The values quoted represent maximal values and were confirmed at various follow-up checks. However, 1 year after thyroidectomy, a female patient with follicular thyroid carcinoma developed an adenocarcinoma of the rectum: The CEA levels measured in this patient were: 4.2 ng/ml 3 weeks after thyroidectomy, 8.4 ng/ml 6 months later, and 37 ng/ml 1 week before operation on the rectum. In none of the other patients with elevated CEA levels were metastases of thyroid cancer, or any other malignancy, detected. (orig.) [de

    Regulatory control of the thyroid gland in horses is similar to other species. Clinical signs of hypothyroidism in adult horses are minimal. Several drugs and physiologic and pathophysiological states can cause circulating thyroid hormone concentrations to be low without actual pathology of the thyroid gland. Thus, nonthyroidal factors must be ruled out before a diagnosis of hypothyroidism can be made. Thyroid hormone supplementation seems to be well tolerated, even in euthyroid horses. Neonatal foals have very high circulating thyroid hormone concentrations, and deficiencies result in significant clinical signs. Unlike in adults, two syndromes of hypothyroidism are well described in foals. Copyright © 2011. Published by Elsevier Inc.

    Full Text Available Protein tyrosine kinase inhibitors are currently an important drug class in the treatment of leukemia. They represent targeted cancer therapy and have become the treatment of choice in chronic myeloid leukemia. Tyrosine kinases are enzymes expressed in multiple tissues and are involved in several signaling pathways influencing cellular growth. Below we describe a patient who developed an unusual complication of tyrosine kinase inhibitor therapy: thyrotoxicosis due to destructive thyroiditis. We review the pathophysiology of tyrosine kinase inhibitor-induced thyroid dysfunction particularly with regard to new second-generation tyrosine kinase inhibitors.

    There are some well known factors involved in the etiology of thyroid cancer, including iodine deficiency, radiation exposure at early ages, or some genetic changes. However, epigenetic modulators that may contribute to development of these tumors and be helpful to for both their diagnosis and treatment have recently been discovered. The currently known changes in DNA methylation, histone modifications, and non-coding RNAs in each type of thyroid carcinoma are reviewed here. Copyright © 2016 SEEN.

    Physiological changes during gestation are important to be aware of in measurement and interpretation of thyroid function tests in women with autoimmune thyroid diseases. Thyroid autoimmune activity is decreasing in pregnancy. Measurement of serum TSH is the first-line screening variable...... for thyroid dysfunction also in pregnancy. However, using serum TSH for control of treatment of maternal thyroid autoimmunity infers a risk for compromised foetal development. Peripheral thyroid hormone values are highly different among laboratories, and there is a need for laboratory-specific gestational age......-related reference ranges. Equally important, the intraindividual variability of the thyroid hormone measurements is much narrower than the interindividual variation (reflecting the reference interval). The best laboratory assessment of thyroid function is a free thyroid hormone estimate combined with TSH...

    Suppurative otitis media (SOM) is a major public health concern worldwide and is associated with increased morbidity. Cases of fungal suppurative otitis media were studied to establish the effect of fungi in otitis media. Ear swabs from 410 patients were collected aseptically using sterile cotton swabs from discharging ear through perforated tympanic membrane. Swabs were subjected to microscopic and culture investigations. The species of fungal growing on Sabouraud's agar were identified using MALDI-TOF MS. For moulds broth micro dilution method following EUCAST guidelines was employed to determine susceptibility patterns against itraconazole, voriconazole and posaconazole. A total of 44 (10.74 %) cases with positive fungal culture growth were studied. The median age of patients with fungal infection was 29.5 (IQR 16-43) years. Of 44 patients; 35 (79.6 %) had pure growth of one type of fungal. Candida albicans was the most common fungus isolated (n = 13; 29.6 %) followed by Aspergillus versicolor (n = 8; 18.2 %). A total of 7 (15.9 %) patients had disease complication at time of enrollment; of them 6 (13.6 %) had hearing loss. On follow up 7 (15.9 %) had poor treatment outcome. All five Aspergillus fumigatus strains resistant itraconazole with reduced susceptibility to voriconazole and posaconazole carried carrying TR34/L98H resistance allele. In addition, all Penicillium citrinum isolates were resistant to voriconazole while all Penicillium sumatrense were resistant to both itraconazole and voriconazole. There were non-significant association of poor treatment outcome and female gender, being HIV positive and being infected with moulds. Fungal infections play a significant role in SOM pathology in our setting. Diagnosis of fungal infections in developing countries should be improved so that appropriate management can be initiated on time to prevent associated complications.

  19. Papillary thyroid carcinoma: does the association with Hashimoto's thyroiditis affect the clinicopathological characteristics of the disease?

    2015-06-01

    Full Text Available INTRODUCTION: Papillary carcinoma is the most common malignant thyroid neoplasm. The effect of the concurrent presence of Hashimoto's thyroiditis and papillary thyroid carcinoma remains controversial. OBJECTIVE: To evaluate the association between Hashimoto's thyroiditis and clinicopathological parameters in thyroid papillary carcinoma cases, based on an historical institutional cohort analysis. METHODS: Cross-sectional study obtained from a historical cohort, including all cases submitted to thyroidectomy for papillary thyroid carcinoma in a single institution during an 11-year period study. RESULTS: A total of 417 patients with papillary thyroid carcinoma were enrolled; 148 (35.4% also had Hashimoto's thyroiditis. A female predominance among cases associated to Hashimoto's thyroiditis was observed. The thyroid tumor, in cases associated with Hashimoto's thyroiditis, had a smaller mean diameter, lower frequency of extra-thyroid extension, and earlier clinicopathological staging. CONCLUSIONS: A high proportion of papillary thyroid carcinoma cases are associated with Hashimoto's thyroiditis. There are associations among these cases with several histopathological factors already recognized for their prognostic value, which by themselves could impact outcomes.

    Understanding the iodine kinetics in the thyroid is useful for the diagnosis of a patient with diffuse thyroid disease. In this study, 9 controls and 50 patients with diffuse thyroid diseases, we evaluated diffuse thyroid diseases with 123 I thyroidal uptake and volume, iodine concentration, and net iodine content measured by computed tomography. There was no significant correlation between volume, iodine concentration, and net iodine content of the thyroid and 123 I thyroidal uptake. The thyroid volume in Graves' and Hashimoto's diseases was significantly larger than that in the control group. The thyroid iodine concentration in Graves' and Hashimoto's diseases was significantly smaller than that in the control group. The thyroid net iodine content in Hashimoto's disease was significantly smaller than that in the control group. Although most of the patients with Graves' disease had more increased radioiodine thyroidal uptake than the control group, there was no significant difference between them in the mean of the thyroid net iodine content. But the variance of net iodine contents in the former was significantly larger than that in the latter. The thyroid net iodine content was very low in all patients with very high thyroglobulin hemaggrugated antibody (TGHA) value although it was nearly normal in some patients with normal TGHA value. It was suggested that iodine concentration and net iodine content might be determined not only by iodine uptake but also by release and/or leakage of iodine compounds from the thyroid, which might depend on some antithyroid antibodies.

  1. Molecular regulation of thyroid gland function.

    Eggo, Margaret C

    2010-10-01

    For de-novo thyroid hormone synthesis ex vivo, thyroid follicular cells require a serum-free medium supplying nutrients, iodide, thyroid-stimulating hormone and insulin-like growth factor I (IGF-I) (or insulin). Under these conditions, T3 and T4 are secreted but so are other factors such as growth factors, plasminogen activators, their inhibitors known as serpins, and so on. What is the function of these factors? Do thyroid cells respond to them or are these paracrine/endocrine factors? The purpose of this review is to highlight the current developments in the identification and role of the signalling pathways that regulate thyroid growth and function and the putative role of endogenous thyroid proteases in regulating this. The roles of the mitogen-activated protein kinases and phosphoinositol 3 kinases and integrins in mediating growth and function in thyroid cancer cells and the roles of plasminogen activators, their receptors and the downstream signalling pathways they modulate have been developed. Discoveries of novel proteases, expressed in thyroid cancers, may be useful in diagnosis. The signalling pathways regulating thyroid activity are examined and the roles of follicular cell products in maintaining thyroid homeostasis evaluated. The possibility that thyroid cell products other than T3 and T4 may circulate and have extrathyroidal effects is proposed.

  2. Thyroid abnormalities after therapeutic external radiation

    The thyroid gland is the largest pure endocrine gland in the body and one of the organs most likely to produce clinically significant abnormalities after therapeutic external radiation. Radiation doses to the thyroid that exceed approximately 26 Gy frequently produce hypothyroidism, which may be clinically overt or subclinical, as manifested by increased serum thyrotropin and normal serum-free thyroxine concentrations. Pituitary or hypothalamic hypothyroidism may arise when the pituitary region receives doses exceeding 50 Gy with conventional, 1.8-2 Gy fractionation. Direct irradiation of the thyroid may increase the risk of Graves' disease or euthyroid Graves' opthalmopathy. Silent thyroiditis, cystic degeneration, benign adenoma, and thyroid cancer have been observed after therapeutically relevant doses of external radiation. Direct or incidental thyroid irradiation increases the risk for well-differentiated, papillary, and follicular thyroid cancer from 15- to 53-fold. Thyroid cancer risk is highest following radiation at a young age, decreases with increasing age at treatment, and increases with follow-up duration. The potentially prolonged latent period between radiation exposure and the development of thyroid dysfunction, thyroid nodularity, and thyroid cancer means that individuals who have received neck or pituitary irradiation require careful, periodic clinical and laboratory evaluation to avoid excess morbidity

    Propofol is a hypnotic agent for induction and maintainance of general anaesthesia and it is used for sedation of critically ill intensive care patients. As a rare adverse effect propofol can cause acute pancreatitis. We report a case of post-operative pancreatitis in an otherwise healthy 62-year-old male who was anaesthezised with propofol during an otherwise uncomplicated surgery for thyroid carcinoma. Other common causes could be excluded. Since this is a possible lethal complication in post-operative patients, medical doctors should be aware of this adverse effect.

    The effect of a Brazilian variety soybean and their comercial products on thyroid gland is studied. Soybean derivatives are tested in rats through acute experiments of 3 to 24 hours and semichronic experiments of 16 to 29 days. The autoclaved extract administered after 6 to 24 hours decreases the percentage of iodine ( 131 I) uptake. Semichronic experiments show that the factor found in soybean provokes both an increase or a reduction in percentage of iodine ( 131 I) uptake, depending ou the oeriod of action [pt

    A study has been done on the determination of thyroid volume by scintigraphic method in comparison to ultrasonographic technique, which involved a healthy woman volunteer, 5 women patients and a man patient with thyroid diseases. Scintigraphic examination upon the patient's thyroid was performed using a gamma camera 20 minutes following the injection of 55.5 Mbq (1.5 mCi) Tc-99m pertechnetate. A computer, with a dedicated program, coupled to the gamma camera was employed in the calculation of thyroid volume based on the scintigraphic data. Subsequent to the scintigraphic study, ultrasonographic determination of thyroid volume was then carried out. Correlation test that was applied to the outcome of the two methods of thyroid volume determination resulted in an excellent coefficient of correlation, R, which was 0.99. This showed a very good correlation between these two different techniques of thyroid volume determination

    The aim of this study is to determine thyroid status in recurrent miscarriage Sudanese women and to determine the association between thyroid antibodies and miscarriage. The study included patients attending obstetrics and gynecology unit at Khartoum teaching hospital and Omdurman New hospital since June 2008 to Jan 2009, these patients were complaining of vaginal bleeding. Sixty, apparently healthy pregnant women with history of unexplained recurrent miscarriages during the first trimester, their ages ranged between 20 and 45 years were selected as target group. Forty healthy, normal pregnant women of the same gestational age and known to reach term and had healthy labor, patients with age ranged between 17 and 41 years were selected from (SAEC), referral clinic center at Khartoum Teaching and Omdurman New Hospitals as control group. The two groups were physically examined and their thyroid glands were seen by the physician. Questionnaires were completed for all the subjects. Patients with metabolic or endocrinologic disorders, genital organ anamoly, uterine myoma, mal nourishment or exposed to toxic substances were excluded from the study. Five ml of venous blood samples were collected from the target and control subjects. Thyroid function test and thyroid antibodies (TT 4 , TT 3 , FT 4 , FT 3 , TSH, TPO-Ab and Tg-Ab) were measured for the two groups (target and control ) using RIA technique. The results of this study showed that there was a significant decrease decrease in the concentrations of thyroid hormones (TT 4 and TT 3 ) in the target group (p-value = 0.0001 and 0.004 respectively) compared with the control group. Moreover, there was a significant elevation in the concentration of TSH in the target group (p- value = 0.0001). The free T-4 concentration was lower but not significant in the target group (p-value=0.075), FT 3 level was similar in both groups (p-value = 0.591). The presence of abnormal high concentrations of TT 4 in control and target groups

    Traditionally, thyroid imaging has been performed primarily using radionuclide scanning. High-resolution computed tomography (CT) was performed in 18 patients to evaluate the CT appearance of various thyroid abnormalities including diffuse toxic goiter, multinodular goiter, Hashimoto thyroiditis, thyroid adenoma, and malignant thyroid tumors. CT images of the thyroid were correlated with radionuclide scanning, surgical findings, and clinical and laboratory results. CT provided a complementary method for evaluation of the thyroid by defining the morphology of the thyroid gland and more precisely defining the anatomic extent of thyroid abnormalities in relation to the normal structures of the neck and mediastinum

    Resistance to thyroid hormone is an uncommon problem, which has rarely been associated with thyroid dysgenesis. We report a case with both thyroid gland ectopy and resistance to thyroid hormone and, thus, a reduced capacity to produce and respond to thyroid hormone. The patient presented at 2 years of age with developmental delay, dysmorphic features, and elevation in both thyroxine and thyrotropin. We document her response to therapy with thyroxine, with particular regard to her growth and development. Persistent elevation of thyrotropin is commonly recognized during treatment of congenital hypothyroidism. Resistance to thyroid hormone may be an important additional diagnosis to consider in cases where thyrotropin remains persistently elevated.

    The link between Hashimoto's thyroiditis and thyroid carcinoma has long been a topic of controversy. The aim of our study was to determine the prevalence of thyroid carcinoma and Hashimoto's thyroiditis coexistence in histopathologic material of thyroidectomized patients. In a retrospective study, the clinicohistopathologic data of 2117 patients (1738 females/379 males), who underwent total or partial thyroidectomy for thyroid gland disorder at a single institution from the 1st of January 2005 to the 31st of December 2014 were analyzed. Thyroid carcinoma was detected in 318 cases (15%) and microcarcinoma (thyroid cancer ≤10mm in diameter) was found in permanent sections in 169 cases (8%). Hashimoto's thyroiditis was detected in 318 (15%) patients. Hashimoto's thyroiditis was significantly more often associated with thyroid carcinoma and microcarcinoma compare to benign condition (p=0.048, p=0.00014, respectively). Coexistence of Hashimoto's thyroiditis and thyroid carcinoma/thyroid microcarcinoma did not affect tumor size (p=0.251, p=0.098, respectively), or tumor multifocality (p=0.831, p=0.957, respectively). Bilateral thyroid microcarcinoma was significantly more often detected when Hashimoto's thyroiditis was also diagnosed (p=0.041), but presence of Hashimoto's thyroiditis did not affect bilateral occurrence of thyroid carcinoma (p=0.731). Hashimoto's thyroiditis is associated with significantly increased risk of developing thyroid carcinoma, especially thyroid microcarcinoma.

    Full Text Available Thyroid hemiagenesis (TH, very rare congenital anomaly, is generally asymptomatic. We report two cases of TH with hyperthyroidism. Case One. The patient presented with signs and symptoms of thyrotoxicosis. Physical examination revealed asymmetric nodular goitre at right lobe. Biochemical analysis revealed the diagnosis of hyperthyroidism. Ultrasound showed multinodular hypertrophy in the right lobe and absence of the left lobe. Nuclear scan, confirming absence of the left lobe, showed hot nodules in the right one. The diagnosis was toxic multinodular goitre. Case Two. The thyroid was not palpable in this patient presented with signs and symptoms of thyrotoxicosis. Biochemical analysis revealed the diagnosis of autoimmune thyrotoxicosis. Ultrasound showed mild diffuse hyperplasia of the right lobe and agenesis of the left lobe. Nuclear scan, confirming absence of the left lobe, showed increasing diffuse uptake of radiotracer in the right one. The diagnosis was Graves’ disease in this patient. After antithyroid medication, the patients were surgically treated with total excision of the thyroid tissue. TH is sometimes associated with disorders of the thyroid. Hyperthyroidism makes TH cases symptomatic. During evaluation of patients, ultrasound and nuclear scan usually report agenesis of one lobe and establish the diagnosis of TH. The surgical treatment is total removal of hyperactive tissue and total excision of the remaining lobe.

    Iodoalbumin has been found in the goiter of Dutch goats with a thyroglobulin synthesis defect. Immunohistochemical studies showed that in the goiter the percentage of follicles containing albumin was higher than that in normal thyroid glands. In the albumin-containing follicles of normal and

    ). This was performed to obtain unaltered serum TSH levels during the trial and between the two treatment groups. Blood sampling was performed 24 h after the last intake of thyroid hormone medication. RESULTS: TSH remained unaltered between the groups ((median) 0.83 vs 1.18 mU/l in T4/T3 combination and T4 monotherapy...

    In order to obtain more diagnostic information by thyroid scintigraphy we used a gamma camera with a high resolution collimator and a computer. This led to an improvement of thyroid scintigrams and their documentation. Additionally it allowed to obtain values for global and regional uptake of pertechnetate before and under suppression. The usefulness of this method was proven by investigation of 50 individuals with normal thyroid function and 32 euthyroid patients with pathological suppressibility in an area of iodine deficiency. In normals global thyroid uptake and its suppression correlated with the FT 4 I and Δ TSH after TRH in dependence of their iodine excretion. Three types of pathological reaction under suppression could be delineated: 1. pure focal autonomy, 2. generalized (disseminated) autonomy, 3. combined focal and disseminated autonomy. The means of Δ TSH decreased stepwise from group 1 to 3 indicating increasing autonomy. The method is predominantly helpful to detect autonomy in euthyroid goitre. It is superior to qualitative evaluation of scintigrams. Additionally it is useful for decisions in therapy, especially for functionally orientated operation. (orig.) [de
