    Full Text Available The ectopic thyroid gland is a rare entity which is mostly found along the line of descent of"nthe thyroid gland. Most of the patients present with midline swelling and usually seek medical"nattention. Dual ectopic thyroid gland is even rarer. The clinical examination and different imaging"nmodalities establish its diagnosis. Radionuclide studies are highly sensitive and specific in"ndemonstrating the functional tissues in patients with ectopic thyroid, thereby guiding further"nmanagement. The authors reported a case of ectopic thyroid gland in a girl with midline neck"nswelling initially, subsequently lost to follow-up. She again presented with enlarged swelling after"na period of three years with dual ectopic thyroid in the neck region on thyroid scan. Thyroid"nscintigraphy demonstrated that progression in the size of ectopic glands was due to neglect in"ntreatment.

    Ectopic thyroid is an uncommon congenital abnormality, but ectopic thyroid tissue can be present anywhere along the course of the thyroglossal duct and the embryologic descent from the base of the tongue. We report here on two cases with the ultrasonograpic findings of dual ectopy of the thyroid, and these findings were well correlated with the findings of nuclear scintigraphy

    The presence of simultaneous two ectopic foci of thyroid tissue (dual ectopic thyroid) is rare, and few cases have been reported in the literature. The ectopic thyroid tissue is an extremely uncommon embryological aberration due to the alterations occurring during the embryological development with incomplete migration of thyroid precursors. Commonly ectopic thyroid tissue is a midline structures, but the lateral location is possible but very rare. Ectopic thyroid is common in women and can vary in size from a microscopic focus to a few centimeters. The normal process of migration of the thyroid can be interrupted at various levels determining a lingual ectopy, a sublingual ectopic, prelaryngeal ectopy, or mediastinic ectopy. Intrathoracic and subdiaphragmatic organs are other sites where the ectopic thyroid tissue may be present. In most of the cases, ectopic tissue is a lingual thyroid and this condition can be totally asymptomatic, discovered incidentally, or occurs with symptoms such as dysphonia, dysphagia, dyspnea, and hemoptysis. Sublingual or suprahyoid ectopia is rare and even rarer are the cases of two foci of ectopic thyroid tissue simultaneously present. On imaging, the ectopic tissue shows the same characteristics of orthotopic thyroid tissue and similarly can undergo goiterous and cancerous transformation. We report a case of incidental dual ectopic thyroid in lingual and suprahyoid level in a 72-year-old female patient, asymptomatic and with normal thyroid function, who underwent computed tomography (CT) angiography before vascular surgery for the treatment of carotid stenosis. The presence of a lingual thyroid can lead to a difficult and dangerous intubation, with possible fatal consequences. For this reason, the discovery of these abnormalities has totally changed the patient management who has been subjected to endovascular treatment, instead to the classical surgery.

    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.

    Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable.

    Full Text Available Lingual thyroid gland is a rare clinical entity. The presence of an ectopic thyroid gland located at the base of the tongue may be presented with symptoms like dysphagia, dysphonia, and upper airway obstruction. We are introducing a case of an 8-year-old girl who had lingual thyroid that presented dysphagia and foreign body sensation in the throat. The diagnostic was reached with clinical examination, thyroid scintigraphy with Tc99m and ultrasound. A laryngoscopy was performed which confirmed a spherical mass at base of tongue. Investigation should include thyroid function tests. In this case we observed subclinical hypothyroidism. There are different types of surgical approaches for the treatment of this condition; however, the treatment with Levothyroxine Sodium allowed the stabilization of TSH levels and clinical improvement of symptoms in a follow-up of 2 years.

    Ectopic thyroid tissue is a congenital disease caused by abnormal migration of thyroid in the embryonic stage. Malignant ectopic thyroid tissue is often misdiagnosed as a cyst of the thyroglossal duct. We treated 2 patients with papillary carcinoma in the anterior midline of the neck from May 1985 to Detober 2002.

    Thyroid cancer is very common, but skull ectopic thyroid cancer has not been reported in 50 years of literatures in foreign countries. There are only four cases of the skull ectopic thyroid cancer reported in more than 30 years of domestic literature including the cases in this report. This paper aims to investigate the clinical characteristics and possible molecular mechanisms of this rare disease. Five keywords of "thyroid gland", "ectopic thyroid", "thyroid cancer", "ectopic thyroid cancer" and "metastatic thyroid cancer" were included and 50 years of literatures in the PubMed-MEDLINE and Wanfang database were reviewed. By combining the test data of 2 cases of surgical patient tissue microarray specimens-molecular immunology pathology, the possible molecular mechanisms were analyzed and molecular regulation network diagram was drawn. The skull ectopic thyroid cancer has not been reported in 50 years of literatures in foreign countries and there are only four cases of the skull ectopic thyroid cancer reported in more than 30 years of domestic literature including the cases in this report. The molecular expressions of skull ectopic thyroid cancer, orthotopic thyroid cancer, and metastatic thyroid cancer were not the same: (I) AKT (P=0.012, 0.002) and mTOR (P=0.002, 0.004) were highly expressed in the skull ectopic thyroid cancer; (II) BRAF (P=0.029, 0.014) and ERK (P=0.002, 0.001) were highly expressed in orthotopic thyroid cancer; (III) MMP-9 (P=0.023, 0.016) was highly expressed in metastatic thyroid cancer. According to the molecular information base, the PI3K is predicted to be a key crossing gene of the above three signaling pathways, which showed no significant differences in these three thyroid cancers (P=0.692, 0.388, 0.227), but PI3K has regulation roles in the three signaling pathways of Akt/mTOR, MAPK, and NF-κB. PI3K gene is an important starting gene of thyroid cancers. After the canceration starts, due to the fact that the local microenvironments of

    Full Text Available Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1–3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it. We present a case of a 33-year-old man with an incidental lateral neck mass diagnosed after a motor vehicle accident. Total thyroidectomy and lymph node resection were completed without evidence of papillary thyroid carcinoma. Malignant transformation of heterotopic thyroid tissue was the final diagnosis. The possibility of an ectopic thyroid cancer should be considered in the differential diagnosis of a pathological mass in the neck. The uniqueness of this case strives in the rarity that the thyroid gland was free of malignancy, despite ectopic tissue being positive for thyroid carcinoma. Management strategies, including performance of total thyroidectomy, neck dissection, and treatment with radioiodine, should be based on individualized risk assessment.

    Full Text Available Developmental abnormalities of the thyroid gland are very rare. The most common abnormalities include ectopic thyroid tissues that are commonly seen in lingual or sublingual location, agenesis, and hemiagenesis of the thyroid gland. These developmental defects may or may not be associated with thyroid dysfunction. Our case is an 18-year-old male who presented with swelling in the neck of 4-year duration. Clinical examination revealed an oval-shape swelling in the left side of the thyroid gland. The ultrasound and the nuclear scan report revealed the presence of thyroid hemiagenesis of the right lobe with isthmus along with double ectopic thyroid tissue at suprahyoid and infrahyoid region. His thyroid function test showed elevated thyroid-stimulating hormone (TSH and normal free T4. We report a very rare case of thyroid hemiagenesis with double ectopic thyroid tissue; and to the best of our knowledge, this is the first report in the world literature.

  13. Transcriptome, methylome and genomic variations analysis of ectopic thyroid glands.

    Full Text Available BACKGROUND: Congenital hypothyroidism from thyroid dysgenesis (CHTD is predominantly a sporadic disease characterized by defects in the differentiation, migration or growth of thyroid tissue. Of these defects, incomplete migration resulting in ectopic thyroid tissue is the most common (up to 80%. Germinal mutations in the thyroid-related transcription factors NKX2.1, FOXE1, PAX-8, and NKX2.5 have been identified in only 3% of patients with sporadic CHTD. Moreover, a survey of monozygotic twins yielded a discordance rate of 92%, suggesting that somatic events, genetic or epigenetic, probably play an important role in the etiology of CHTD. METHODOLOGY/PRINCIPAL FINDINGS: To assess the role of somatic genetic or epigenetic processes in CHTD, we analyzed gene expression, genome-wide methylation, and structural genome variations in normal versus ectopic thyroid tissue. In total, 1011 genes were more than two-fold induced or repressed. Expression array was validated by quantitative real-time RT-PCR for 100 genes. After correction for differences in thyroid activation state, 19 genes were exclusively associated with thyroid ectopy, among which genes involved in embryonic development (e.g. TXNIP and in the Wnt pathway (e.g. SFRP2 and FRZB were observed. None of the thyroid related transcription factors (FOXE1, HHEX, NKX2.1, NKX2.5 showed decreased expression, whereas PAX8 expression was associated with thyroid activation state. Finally, the expression profile was independent of promoter and CpG island methylation and of structural genome variations. CONCLUSIONS/SIGNIFICANCE: This is the first integrative molecular analysis of ectopic thyroid tissue. Ectopic thyroids show a differential gene expression compared to that of normal thyroids, although molecular basis could not be defined. Replication of this pilot study on a larger cohort could lead to unraveling the elusive cause of defective thyroid migration during embryogenesis.

    Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is caused most frequently by a bronchial carcinoid tumor or by small cell lung cancer. Medullary thyroid carcinoma (MTC is a rare etiology of ectopic ACTH syndrome. We describe a case of Cushing syndrome due to ectopic ACTH production from MTC in a 48-year-old male. He was diagnosed with MTC 14 years ago and underwent total thyroidectomy, cervical lymph node dissection and a series of metastasectomies. MTC was confirmed by the pathological examination of the thyroid and metastatic mediastinal lymph node tissues. Two years after his last surgery, he developed Cushingoid features, such as moon face and central obesity, accompanied by uncontrolled hypertension and new-onset diabetes. The laboratory results were compatible with ectopic ACTH syndrome. A bilateral adrenalectomy improved the clinical and laboratory findings that were associated with Cushing syndrome. This is the first confirmed case of ectopic ACTH syndrome caused by MTC in Korea.

    The accessory midline thyroids are ascribed to an arrest of migration of the median thyroid anlage, while the lateral ectopic thyroids have induced a hypothesis of the presence of lateral thyroid anlage. We report the case of a 67-year-old man who presented with dyspnea and dysphagia of 1 year's duration. The clinical examination and radiological investigations (CT and MRI) showed a solid heterogeneous mass in the right parapharyngeal space. The fine needle aspiration biopsy was inconsistent. The mass (3x2.5x3.5 cm) was excised via a transoral approach. It was capsulated with an elastic consistency and showed a nodular appearance on the cut surface. Histological examination revealed thyroid tissue with the characteristics of colloid goiter. The postoperative (99m)Tc-pertechnetate scan showed the normal thyroid gland located in the usual pretracheal site. The absence of malignancy, at histology and immunohistochemistry, allows a metastatic nature of the mass to be ruled out, and accounts for a supernumerary thyroid. The occurrence of a parapharyngeal thyroid, although extremely rare, is worth bearing in mind as a possible ectopic location. This case also supports the hypothesized role of the lateral thyroid anlage in man deriving from the ultimo-branchial body in the morphogenesis of the lateral lobe of the thyroid gland.

    Foci of ectopic thyroid tissue are uncommon. Most sites of thyroid ectopia are confined to the neck region. The presence of ectopic thyroid tissue outside the migration pathway of the primitive thyroid in other locations is exceptional. Given that any disease of the thyroid gland may also affect ectopic thyroid tissue, pathologists has to recognize benign or malignant conditions that may develop in the ectopic focus. We present the case of a 32-year-old woman with ectopic thyroid parenchyma in the adrenal gland. Clinically, postoperative thyroid ultrasound echography and computed tomography scans did not reveal any thyroid tumor. The ectopic tissue was a cyst bordered by mature follicular thyroid structures and was histologically benign, without the molecular alterations associated with malignant tumors of follicular cell derivation (BRAFV600E, N-RAS, H-RAS, K-RAS). Review of the literature reveals that adrenal ectopic thyroid tissue is nearly always cystic and has distinctive pathologic features. © The Author(s) 2014.

    Full Text Available Adrenal incidentalomas are clinical dilemmas for the clinicians. The work up, to differentiate between malignant and benign lesions, and hyperfunctioning and nonfunctioning lesions is mandatory before the consideration of surgical resection. Ectopic thyroid tissue located in the adrenal gland (ETTAG is a very rare condition. We report a case of ETTAG presenting with adrenal incidentaloma. A 57-year-old woman was admitted with incidental right adrenal mass. Hormone evaluation showed no hormonal activity. Magnetic resonance imaging revealed a 20x17 mm lobulated solid mass, which contained millimetric hypointense nodular areas consistent with calcifications. Loss of signal intensity on out-of-phase could not be evaluated because of the calcifications. Right adrenalectomy was performed to establish the histopathological diagnosis and to rule out malignancy. Histopathological diagnosis revealed ETTAG. Her medical history was positive for multinodular goiter and bilateral subtotal thyroidectomy 32 years ago. Thyroid ultrasonography showed residual thyroid tissue in both the right and left lobes, and colloid thyroid nodules. Fine needle aspiration biopsy from the nodules revealed benign nodules. The patient has been followed up for six years, and no change in thyroid nodule sizes and no evidence of metastatic foci have been detected. ETTAG would be considered in the differential diagnosis of adrenal mass showing no hormonal activity, especially when magnetic resonance images are not consistent with adrenal adenoma. Long follow-up duration of this case suggests that it was a benign condition.

    Ectopic thyroid tissue remains a rare developmental abnormality involving defective or aberrant embryogenesis of the thyroid gland during its passage from the floor of the primitive foregut to its usual final position in pre-tracheal region of the neck. Its specific prevalence accounts about 1 case per 100.000-300.000 persons and one in 4.000-8.000 patients with thyroid disease show this condition. The cause of this defect is not fully known. Despite genetic factors have been associated with thyroid gland morphogenesis and differentiation, just recently some mutation has been associated with human thyroid ectopy. Lingual region in the most common site of thyroid ectopy but ectopic thyroid tissue were found in other head and neck locations. Nevertheless, aberrant ectopic thyroid tissue has been found in other places distant from the neck region. Ectopic tissue is affected by different pathological changes that occur in the normal eutopic thyroid. Patients may present insidiously or as an emergency. Diagnostic management of thyroid ectopy is performed by radionuclide thyroid imaging, ultrasonography, CT scan, MRI, biopsy and thyroid function tests. Asymptomatic euthyroid patients with ectopic thyroid do not usually require therapy but are kept under observation. For those with symptoms, treatment depends on size of the gland, nature of symptoms, thyroid function status and histological findings. Surgical excision is often required as treatment for this condition.

  19. Thyroid papillary carcinoma arising in ectopic thyroid tissue within a neck branchial cyst

    2006-05-01

    Full Text Available Abstract Background Thyroid gland derives from one median anlage at the base of the tongue, and from the two fourth branchial pouches. A number of anomalies may occur during their migration. These can be in form of ectopic tissues, which are frequently found along the course of thyroglossal duct and rarely in other sites, many of these may develop same diseases as the thyroid gland. Case presentation A 36-years-old female presented with a 3 month history of left side neck mass. The mass disappeared following aspiration of brown colored fluid, which on cytological examination showed cells with nuclear irregularities that warranted the resection of the lesion. The histology demonstrated a thyroid papillary carcinoma arising within the branchial cyst. Thereafter, the patient underwent a total thyroidectomy with central lymph nodes dissection. Histology showed a multifocal papillary carcinoma with central lymph nodes metastases. Only four cases of primary thyroid carcinomas in neck branchial cyst have been described so far. Conclusion In a lateral cystic neck mass, although rare, occurrence of ectopic thyroid tissue and presence of a papillary thyroid carcinoma should be kept in mind.

    The intraperitoneal injection of polycylic aromatic hydrocarbons in young Amazon mollies induces proliferation of ectopic thyroid tissue in the spleen. The authors have surveyed untreated mollies, Poecilia formosa, and four closely related poeciliid fishes to see if ectopic thyroid tissue occurs normally in the spleen. If this were the case, it is possible that the tissue may have been stimulated to proliferate by the injected compounds. We found no instances of ectopic thyroid at any site in 50 untreated Amazon mollies examined nor in some 50 spleens dissected from other untreated fish. Splenic thyroid tissue was found in five guppies from 50 surveyed, but did not occur in other species.

    Ectopic thyroid tissue of nasopharynx is an uncommon phenomenon and papillary thyroid carcinoma arising from the tissue is extremely rare. The authors report a rare case of 16-year-old girl with papillary thyroid carcinoma of nasopharynx. Clinicians were ever confused by adenoid hypertrophy and solved the diagnostic dilemma by adequate examinations. In the case, we mainly emphasize that surgeons should be aware of and actively consider such a possibility of ectopic papillary thyroid carcinoma of nasopharynx in children and adolescents with long-term nasal obstruction, even if thyroid carcinoma is a rare tumor.

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    2017-01-01

    Ectopic thyroid tissue is a rare entity and when discovered it is typically along the pathway of embryologic migration of the thyroid. We present a case of incidental finding of ectopic thyroid tissue within mediastinum in a 61-year-old female patient with a history of total thyroidectomy for thyroiditis and nodules. The patient presented to emergency room with cough and right chest pain and underwent a chest computed tomographic angiogram (CTA) to exclude pulmonary embolism as part of chest pain workup. One right paratracheal mediastinal soft tissue nodule was visualized on the images of CTA. This right paratracheal soft tissue mass was found to be ectopic benign thyroid tissue by histological analysis of the biopsied tissue samples. The function of this ectopic thyroid tissue was characterized by I-123 radioiodine uptake and single photon emission computed tomography/computed tomography (SPECT/CT) imaging. This case illustrates that ectopic thyroid tissue should be included for differential diagnosis of a hyperdense soft tissue mass located within mediastinum. I-123 SPECT/CT is useful for guiding tissue biopsy of ectopic thyroid tissue distant from orthotopic thyroid gland and functional and anatomic characterization of mediastinal ectopic thyroid tissue for surgical resection when it is medically necessary.

    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.

    Background: Ectopic thyroid tissue is usually found anywhere along the embryonic descent pathway of the medial thyroid anlage from the tongue to the trachea (Wölfler area). However, ectopic thyroid tissue in the adrenal gland (ETTAG) is not easy to understand on the basis of thyroid embryology; because it is so rare, the possibility of metastasis should first be considered. Here, we describe two cases of ETTAG with pathogenetic implications and review the associated literature. Patient findings: Two cases of ETTAG presented as incidental cystic adrenal masses in adult females, one having a congenital hernia of Morgagni. The ETTAG was histologically indistinguishable from normal orthotopic thyroid tissue, and its follicular nature was confirmed by immunohistochemical positivity for thyroglobulin, thyroperoxidase, thyroid transcription factor-1 (TTF-1/Titf-1/Nkx2.1), cytokeratin AE1/AE3, cytokeratin 7, pendrin, human sodium iodide symporter, paired box gene 8, and forkhead box E1 (TTF-2), as well as positivity for the messenger RNA of the thyroglobulin gene by in situ hybridization analysis. No C cells (negativity for calcitonin, chromogranin, and synaptophysin) were present. Neither BRAF nor KRAS mutations were detected with real-time polymerase chain reaction analysis. Further work-up did not show evidence of thyroid malignancy. Summary: ETTAG is a rare finding, with only seven cases reported; women are much more frequently affected than men (8:1), and it usually presents in the fifth decade (mean age 54, range 38–67) as a cystic adrenal mass incidentally discovered on abdominal ultrasonography and/or in computed tomography images. ETTAG is composed of normal follicular cells without C cells. The expression of some transcription factors (TTF-1, paired box gene 8, and FOXE1) involved in development and/or migration of the medial thyroid anlage is preserved. Coexistence of a congenital hernia of Morgagni in one patient suggests an overdescent of medial thyroid

    Medullary thyroid carcinoma (MTC) may rarely present with paraneoplastic syndromes. Among the most frequent ones are the appearance of diarrhea and ectopic Cushing syndrome (ECS). The ECS in the context of MTC is usually present in patients with distant metastatic disease. The use of drugs such as ketoconazole, metyrapone, somatostatin analogs and etomidate have been ineffective alternatives to control hypercortisolism in these patients. Bilateral adrenalectomy is often required to manage this situation. Recently, the use of tyrosine kinase inhibitors has been shown to be a useful tool to achieve eucortisolism in patients with metastatic MTC and ECS. We present a patient with sporadic advanced persistent and progressive MTC with lymph node and liver metastases, which after 16 years of followup developed an ECS. After one month of 300 mg/day vandetanib treatment, a biochemical and clinical response of the ECS was achieved but it did not result in significant reduction of tumor burden. However the patient reached criteria for stable disease according to response evaluation criteria in solid tumors (RECIST 1.1) after 8 months of follow-up. (author)

    Background The incidence of thyroid cancer has been increasing.Our aim was to evaluate the efficacy of low-dose dualphase helical computed tomography (CT) in the characterization of thyroid lesions,and to discuss the relationship between image characteristics and their pathology.Methods One hundred and six patients with thyroid lesions underwent low-dose dual-phase helical CT after the injection of contrast material.CT scans were obtained at arterial and venous phase with delays of 25 and 65 seconds,and tube current of 60 and 120 mA,respectively.The attenuation change in the lesion between the arterial and venous phase was analyzed and categorized as "increased," "decreased," "mixed" or "no change." Results Histopathologic diagnosis was obtained by surgery in 106 patients (115 lesions).Of the 106 patients,45 had nodular goiter,5 thyroid adenoma,6 thyroiditis,and 50 papillary thyroid carcinoma (PTC) (59 lesions).The attenuation value showed a significant difference (P <0.05) between the arterial and venous phase for the high attenuation area.There was statistical significant difference in terms of attenuation value in high attenuation areas at both phases and in low attenuation areas on arterial phase between nodular goiter and PTC (P <0.05).However,there was no significant difference in attenuation value between adenoma and PTC.Twenty-nine cases (76.3%) of goiter manifested mixed type,3 cases (3/5) of adenoma showed decreased type,6 cases (6/6) of thyroiditis showed increased type,and 55 cases (93.2%) of PTC showed decreased type attenuation.The sensitivity,specificity for thyroid carcinoma by dual-phase CT were 94.9% and 80.4% respectively.The overall diagnostic accuracy for thyroid lesions by dual-phase CT was 87.8%.Conclusions The performance of dual-phase helical CT is related to the pathological structure of the lesions.The analysis of enhancement patterns by using dual-phase helical CT will be helpful in the differential diagnosis of thyroid

    Aim: To examine the usefulness of dual-phase 2-[{sup 18}F]-fluoro-2-deoxy-D-glucose (FDG) positron-emission tomography (PET) for the evaluation of thyroid incidentalomas. Materials and methods: In this retrospective study, cases with focal thyroid lesions seen incidentally at FDG PET in which the histopathological diagnosis was available and in which dual-phase FDG PET imaging was performed at 1 and 2 h after FDG injection were reviewed. In the included cases, the 1 and 2 h maximal standard uptake value (1-hour maximal SUV and 2-hour maximal SUV, respectively) and retention index (RI) were calculated, and the differences between benign and malignant thyroid incidentalomas were analysed. Receiver operating characteristic (ROC) analysis was performed to evaluate the ability of 1-hour maximal SUV, 2-hour maximal SUV, and RI to discriminate benign from malignant lesions. Results: A total of 39 patients (25 females, 14 males) with 45 lesions (17 malignant, 28 benign) were included. In malignant thyroid incidentalomas, the average 1-hour maximal SUV, 2-hour maximal SUV, and RI were 5.20, 5.72, and 7.67%, respectively, and in benign thyroid incidentalomas the values were 4.67, 4.97, and 7.38%, respectively. There were no significant differences in 1-hour maximal SUV, 2-hour maximal SUV, and RI between benign and malignant lesions. The area under the ROC curve did not differ from 0.5. Conclusion: Dual-phase FDG PET is not useful for differentiating benign from malignant thyroid incidentalomas.

    A single intraperitoneal injection of any one of several polycyclic aromatic hydrocarbons given to young Amazon mollies induces massive enlargement of the spleen. This enlargement is the result of splenic tissue being partially or wholly replaced by proliferating thyroid tissue. The pharyngeal thyroid gland is stimulated but to a lesser degree. No exuberant thyroid tissue is found at any other extrapharyngeal site. We discuss the possible causes of this finding.

    Se presenta una paciente con tumor palpable ubicado en línea media de la región anterior del cuello, encima del hueso hioides, diagnosticado inicialmente como quiste del conducto tirogloso. Se realizó estudio preliminar, tanto clínico, como radiológico y citológico de la lesión. Mediante cirugía por técnica convencional, se extrajo el tumor. La biopsia por parafina definió la existencia de tiroides con carcinoma papilar. Añadido a dicha condición, la paciente presentaba glándula tiroidea en ubicación normal. Se considera un caso curioso, donde se mezclan los conceptos de duplicidad tiroidea y tiroides ectópico, con la presencia en este último de un carcinoma papilar.

    We present the case of a patient with a palpable tumor located in midline of the anterior neck above the hyoid bone, initially diagnosed as a thyroglossal duct cyst. Preliminary study of the lesion was conducted, both clinically and radiologically and cytologically. The tumor was removed through surgery by conventional technique. The paraffin biopsy defined the existence of thyroid papillary carcinoma. Despite this condition, the patient had thyroid gland in normal location. It is considered to be a curious case, combining the concepts of thyroid duplication and ectopic thyroid, with the presence, in this last one, of papillary carcinoma.

    The diagnosis of thyroiditis encompasses a broad spectrum of thyroid disorders. Analysis of signs and symptoms, biochemical changes, neck ultrasound characteristics and radioactive iodine uptake values allows an accurate diagnosis. Recent studies of the whole genome have helped to identify many susceptibility genes for autoimmune thyroiditis. However, none of these genes contribute to a significant increase in risk of developing this thyroiditis. Clinical awareness of the characteristic presentations of exceptional thyroiditis (acute suppurative thyroiditis, Riedel's thyroiditis) is an important issue. Selenium administration seems to be beneficial for reducing the incidence of thyroiditis. Finally, certain drug-induced thyroiditis remains a therapeutic challenge for the physician.

    Full Text Available The possibility of a coincidental appearance of hyperparathyroidism and thyroid cancer is not often considered because of its low incidence. Here, we present a case of a 49-year-old woman with a parathyroid adenoma coexisting with two sites of papillary thyroid carcinoma. Dual-phase 99mTc-methoxyisobutylisonitrile (MIBI parathyroid imaging before the operation correctly visualized the site of the parathyroid adenoma. In addition, two papillary thyroid carcinomas showed faint uptake of 99mTc-MIBI on delayed image. Total thyroidectomy and parathyroidectomy of a solitary parathyroid adenoma were performed. The patient subsequently underwent radioiodine-131 ablation and was treated with T4 suppression. This case illustrates the need for clinical awareness of concomitant hyperparathyroidism and thyroid cancer. Dual-phase 99mTc-MIBI parathyroid imaging may be useful for detecting indolent thyroid cancer before it becomes a distinct disease.

    Purpose. To investigate the effects of Corbrin Capsule (CS-C-Q80), a drug derived from Cordyceps sinensis (Berk.) Sacc., on autoimmune thyroid diseases (AITD). Methods. 44 Patients with Graves's disease (GD) and 56 patients with Hashimoto's thyroiditis (HT) were randomly assigned to treatment group (GD-Tx and HT-Tx) or control group (GD-Ct and HT-Ct). The control groups were given methimazole or levothyroxine only while the treatment groups were given Corbrin Capsule (2.0 g tid) besides the same conventional prescriptions as control groups. Thyroid hormones, thyroid antibodies, and T lymphocyte subsets were quantified at baseline and 24 weeks posttreatment. Results. Significant drop of serum anti-TPO-Ab levels was observed in both GD-Tx and HT-Tx groups. Before treatment, GD patients had higher helper T cells compared to cytotoxic T cells, while HT patients suffered from a nearly inverted proportion of helper T/cytotoxic T cells. There was a significant drop of the helper T/cytotoxic T cells ratio in GD-Tx to the median of the normal ranges after Corbrin treatment for 24 weeks, while that in HT-Tx was elevated. Conclusion. Corbrin Capsule could restore the balance between helper T and cytotoxic T cells in both GD and HT patients with dual-directional immunomodulatory effects. And it could significantly reduce the autoantibody levels in both GD and HT. PMID:27721890

    Papillary thyroid carcinoma (PTC), the most common thyroid malignancy, usually possesses BRAF mutation or rearranged in translation (RET)/PTC rearrangements. PTC usually possesses BRAF mutation or RET/PTC rearrangements. The mutation status of patients with recurrent PTC has never been characterized in a large population. Mutation status was determined in a cohort of 54 patients with recurrent PTC and analyzed for clinicopathologic relationships. BRAF and ras mutations were determined by PCR and sequencing of genomic DNA. RET/PTC rearrangements were analyzed by reverse transcription-PCR. BRAF mutation in exon 15 (V600E) was found in 42/54 (77.8%) recurrent PTC patients. The RET/PTC rearrangements were detected in 9 of 54 (16.7%) patients. In addition, 5 of 54 (9.3%) recurrent PTC patients had both a BRAF mutation and a RET/PTC rearrangement. The prevalence of tumors with dual mutations found in the recurrent population far exceeds the frequency historically reported for patients with primary PTC. Patients with dual mutations were significantly older (80% older than 45 years) than patients with a BRAF mutation alone (38% older than 45 years). Recurrent PTC is significantly associated with a predominant BRAF mutation. RET/PTC rearrangements, although commonly associated with primary PTCs in younger patients, are uncommonly found in recurrent PTC patients. In addition, the incidence of dual mutations was higher in patients with recurrent PTC than in those primary PTC, as reported by others.

    Thyroid-stimulating hormone (TSH) secretion plays a critical role in regulating thyroid gland function and circulating thyroid hormones (i.e., thyroxine (T4) and triiodothyronine (T3)). A novel multi-immunoreaction-based dual-color capillary electrophoresis (CE) technique was investigated in this study to assess its reliability in diagnosing thyroid gland disease via simultaneous detection of TSH, T3, and T4 in a single run of CE. Compared to the conventional immunoreaction technique, multi-immunoreaction of biotinylated streptavidin antibodies increased the selectivity and sensitivity for individual hormones in human blood samples. Dual-color laser-induced fluorescence (LIF) detection-based CE performed in a running buffer of 25mM Na2B4O7-NaOH (pH 9.3) allowed for fast, simultaneous quantitative analysis of three target thyroid hormones using different excited wavelengths within 3.2min. This process had excellent sensitivity and detection limits of 0.05-5.32 fM. The results showed 1000-100,000 times higher detection sensitivity than previous methods. Method validation with enzyme linked immunosorbent assay for application with human blood samples showed that the CE method was not significantly different at the 98% confidence level. Therefore, the developed CE-LIF method has the advantages of high detection sensitivity, faster analysis time, and smaller sample amount compared to the conventional methods The combined multi-immunoreaction and dual-color CE-LIF method should have increased diagnostic reliability for thyroid gland disease compared to conventional methods based on its highly sensitive detection of thyroid hormones using a single injection and high-throughput screening.

    Technetium-99m tetrofosmin, a lipophilic cationic complex molecule, was introduced for myocardial imaging. In some biodistribution studies it has also been reported to accumulate in the thyroid gland. Our objectives were to determine which thyroid nodules retain tetrofosmin and whether preoperative evaluation of malignancy is possible. Tetrofosmin scintigraphy was performed in 57 patients with a cold thyroid nodule on previously performed pertechnetate scintigraphy. All patients had undergone ultrasonography and sonographically guided fine-needle aspiration biopsy. The tetrofosmin scintigrams were obtained 5 min (early image) and 1 h (late image) after intravenous injection of 370 MBq. Only nodules that showed clear tracer retention after 1 h in comparison with retention at 5 min were classified as TETRO positive. Nodules without late retention were classified as TETRO negative. All patients underwent surgery and the histological results were compared with the results of tetrofosmin scintigraphy. Ten out of 11 patients with thyroid carcinoma (two pT1, three pT2, five pT4) were TETRO negative. One patient with papillary carcinoma (pT2) was TETRO positive. The mean nodular to thyroid tissue (N/T) ratio for the late scan was 1.0{+-}0.20. There were 21 patients with thyroid adenomas (seven follicular, seven microfollicular and seven oxyphilic); 15 of these patients were TETRO positive and six TETRO negative. The mean N/T ratio for the late images was 1.34{+-}0.41. All patients with degenerative goitre (24 cases) and the one patient with Hashimoto`s disease were TETRO negative after 1 h and the N/T ratio was 0.92{+-}0.12 on the late scan. Our results indicate that {sup 99m}Tc-tetrofosmin scanning is of little value preoperatively in distinguishing thyroid carcinoma from other thyroid nodules. Tetrofosmin tends to demonstrate thyroid adenomas but does not have a routine role in the assessment of thyroid nodules. (orig.). With 2 figs., 4 tabs.

    Technetium-99m tetrofosmin, a lipophilic cationic complex molecule, was introduced for myocardial imaging. In some biodistribution studies it has also been reported to accumulate in the thyroid gland. Our objectives were to determine which thyroid nodules retain tetrofosmin and whether preoperative evaluation of malignancy is possible. Tetrofosmin scintigraphy was performed in 57 patients with a cold thyroid nodule on previously performed pertechnetate scintigraphy. All patients had undergone ultrasonography and sonographically guided fine-needle aspiration biopsy. The tetrofosmin scintigrams were obtained 5 min (early image) and 1 h (late image) after intravenous injection of 370 MBq. Only nodules that showed clear tracer retention after 1 h in comparison with retention at 5 min were classified as TETRO positive. Nodules without late retention were classified as TETRO negative. All patients underwent surgery and the histological results were compared with the results of tetrofosmin scintigraphy. Ten out of 11 patients with thyroid carcinoma (two pT1, three pT2, five pT4) were TETRO negative. One patient with papillary carcinoma (pT2) was TETRO positive. The mean nodular to thyroid tissue (N/T) ratio for the late scan was 1.0+/-0.20. There were 21 patients with thyroid adenomas (seven follicular, seven microfollicular and seven oxyphilic); 15 of these patients were TETRO positive and six TETRO negative. The mean N/T ratio for the late images was 1.34+/-0.41. All patients with degenerative goitre (24 cases) and the one patient with Hashimoto's disease were TETRO negative after 1 h and the N/T ratio was 0.92+/-0.12 on the late scan. Our results indicate that 99mTc-tetrofosmin scanning is of little value preoperatively in distinguishing thyroid carcinoma from other thyroid nodules. Tetrofosmin tends to demonstrate thyroid adenomas but does not have a routine role in the assessment of thyroid nodules.

    Thyroid incidentalomas are common findings during imaging studies including {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) for cancer evaluation. Although the overall incidence of incidental thyroid uptake detected on PET imaging is low, clinical attention should be warranted owing to the high incidence of harboring primary thyroid malignancy.We retrospectively reviewed 2,368 dual-time-point {sup 18}F-FDG PET/CT cases that were undertaken for cancer evaluation from November 2007 to February 2009, to determine the clinical impact of dual-time-point imaging in the differential diagnosis of thyroid incidentalomas. Focal thyroid uptake was identified in 64 PET cases and final diagnosis was clarified with cytology/histology in a total of 27 patients with {sup 18}F-FDG-avid incidental thyroid lesion. The maximum standardized uptake value (SUVmax) of the initial image (SUV1) and SUVmax of the delayed image (SUV2) were determined, and the retention index (RI) was calculated by dividing the difference between SUV2 and SUV1 by SUV1 (i. e., RI=[SUV2-SUV1]/SUV1Χ100). These indices were compared between patient groups that were proven to have pathologically benign or malignant thyroid lesions. There was no statistically significant difference in SUV1 between benign and malignant lesions. SUV2 and RI of the malignant lesions were significantly higher than the benign lesions. The areas under the ROC curves showed that SUV2 and RI have the ability to discriminate between benign and malignant thyroid lesions. The predictability of dual-time-point PET parameters for thyroid malignancy was assessed by ROC curve analyses. When SUV2 of 3.9 was used as cut-off threshold, malignancy on the pathology could be predicted with a sensitivity of 87.5 % and specificity of 75 %. A thyroid lesion that shows RI greater than 12.5 % could be expected to be malignant (sensitivity 88.9 %, specificity 66.3 %). All malignant lesions showed an

    Thyroid incidentalomas are common findings during imaging studies including (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for cancer evaluation. Although the overall incidence of incidental thyroid uptake detected on PET imaging is low, clinical attention should be warranted owing to the high incidence of harboring primary thyroid malignancy.

Focal thyroid uptake was identified in 64 PET cases and final diagnosis was clarified with cytology/histology in a total of 27 patients with (18)F-FDG-avid incidental thyroid lesion. The maximum standardized uptake value (SUVmax) of the initial image (SUV1) and SUVmax of the delayed image (SUV2) were determined, and the retention index (RI) was calculated by dividing the difference between SUV2 and SUV1 by SUV1 (i.e., RI = [SUV2 - SUV1]/SUV1 × 100). These indices were compared between patient groups that were proven to have pathologically benign or malignant thyroid lesions. There was no statistically significant difference in SUV1 between benign and malignant lesions. SUV2 and RI of the malignant lesions were significantly higher than the benign lesions.

    Calcium deposition can be observed in many tissues in addition to bones and teeth which physiologically calcify. This unphysiological calcification can damage several organs. It has been shown that vascular calcification which is a risk factor for cardiovascular events develops through similar mechanisms to physiological calcification. Further studies to clarify detailed mechanisms of calcification are necessary to develop measures that inhibit unphysiological ectopic calcification without affecting physiological calcification in bones and teeth.

    Differentiated thyroid carcinoma (DTC) though usually behaves in an indolent manner, can have unusual metastatic presentation. Initial presentation of metastatic disease has been reported in 1–12% of DTC being less frequent in papillary (~2%) than in follicular (~10%) thyroid carcinoma. Renal metastasis from DTC is very rare. To our knowledge, only about 30 cases have been reported in the English literature to date. To make clinicians aware that management of such high-risk thyroid cancer frequently requires novel multimodality imaging and therapeutic techniques. A 72-year-old female is described who presented with abdominal pain and bilateral lower limbs swelling. Initial contrast enhanced computed tomography (CT) scan of abdomen showed a well-encapsulated mass in the upper pole of right kidney favoring a renal cell carcinoma. Postright sided radical nephrectomy, histopathology, and immunohistochemistry reports suggested metastatic deposits from thyroid malignancy. 18F-fluorodeoxyglucose (FDG) positron emission tomography-CT demonstrated hypermetabolic nodule in the left lobe of thyroid and a lytic lesion involving left acetabulum suggestive of skeletal metastasis. Subsequently, ultrasound-guided fine needle aspiration cytology of the thyroid nodules in bilateral lobes confirmed thyroid malignancy (Bethesda 6/6). Total thyroidectomy revealed papillary thyroid cancer (PTC) (follicular variant-PTC [FV-PTC]). After surgery, 131I-whole body scan showed iodine avid lytic lesion in the left acetabulum. The present case is a rare scenario of a renal metastasis as the presenting feature of an FV-PTC. Dual avidity in metastatic thyroid cancers (iodine and FDG) is rare and based on the degree of dedifferentiation of the DTC. PMID:28242987

    Full Text Available Objective: Thyroid ectopy is a rare condition resulting from abnormal embryologic development and migration of the gland. Sublingual is the most common thyroid ectopy; all other ectopic thyroid locations occur very rare. There are no reports in the literature that describe the clinical course of patients with congenital hypothyroidism due to thyroid ectopy. Methods and Results: We present a child with congenital hypothyroidism detected on neonatal screening which had a subclinical course during follow-up. Scintigraphy revealed submental thyroid ectopy, a rare ectopic location and no orthotopic thyroid gland. Conclusion: Our case is unique because of the rare ectopic thyroid location but also of the unexpected clinical course; however, further thyroid monitoring is required for the therapy adjustment and detection of any changes in the ectopic tissue.

    We present the case of a 45-year-old man with a long-standing history of a slow-growing left submandibular mass. Imaging was diagnostic as it disclosed an absent orthotopic thyroid gland and heterogeneous masses, with both solid and cystic components, as well as calcifications in the left sublingual/submandibular space and in the left paramedian aspect of the tongue base, consistent with double thyroid ectopia, originating from central and lateral thyroid anlages, respectively. Pathology confirmed an ectopic thyroid goiter in the left submandibular space with an incidental papillary microcarcinoma. Scintigraphy also demonstrated ectopic thyroid tissue in the left tongue base. (orig.)

    Ectopic parathyroid glands result from aberrant migration during early stages of development and lack of successful identification may lead to lack of success in parathyroid surgery. They constitute a common etiology of persistent or recurrent hyperparathyroidism, when they are missed at initial diagnosis. Their prevalence is about 2-43% in anatomical series and up to 16% and 14% in patients with primary and secondary hyperparathyroidism, respectively. Ectopic inferior parathyroids are most frequently found in the anterior mediastinum, in association with the thymus or the thyroid gland, while the most common position for ectopic superior parathyroids is the tracheoesophageal groove and retroesophageal region. Neck ultrasound and 99mTc Sestamibi scan are first-line imaging modalities, although with low sensitivity and specificity. However, their combination with modern techniques, such as single photon emission computed tomography (SPECT) alone or in combination with CT (SPECT/CT) increases their diagnostic accuracy. Fine needle-aspiration cytology of a lesion suspicious for parathyroid tissue and measurement of parathyroid hormone (PTH) in the aspired material further assist to the successful preoperative localization of ectopic glands. Common sites for surgical investigation are the upper thyroid pole and the upper vascular thyroid stalk behind the hypopharynx and cervical esophagus for the superior parathyroids, and the carotid artery bifurcation and the thymic tongue, for the inferior parathyroids. Radioguided minimally invasive parathyroidectomy after successful localization, assisted by rapid PTH measurement postoperatively, significantly improves surgical outcomes in patients with ectopic parathyroid adenomas.

    Endotracheal ectopic thyroid tissue is rare. It can cause gradual obstruction of the tracheal lumen culminating in sudden dyspnoea. The diagnosis is relatively easy to make with the aid of a laryngeal mirror, by endoscopy, or by x-rays. However, it is most important to take the clinical picture into consideration. It is thought that the ectopic tissue arises from splitting of the thyroid gland during the descent in the embryonal stage. Treatment consists of removal via a tracheofissure. The tracheal mucous membrane must be treated with special care to prevent cicatricial stenosis of the trachea.

    Scar ectopic pregnancy is the rarest form of ectopic pregnancy and has been increasingly diagnosed all over the world. This is a life-threatening form of abnormal implantation of embryo within the myometrium and fibrous tissues in a previous scar on the uterus, especially following caesarean section. With the increasing rate of caesarean section, there is a substantial increase in this condition with better understanding of this disease. The early and accurate diagnosis with timely management can prevent pregnancy complications such as haemorrhage, uterine rupture and can preserve fertility.

    Full Text Available Hidradenoma papilliferum is a rare tumor that occurs almost exclusively in females on the anogenital area. Rare cases of ectopic (nongenital hidradenoma papilliferum have been described. The lesions usually present as an asymptomatic slow-growing, red, firm, mobile, well-delimitated nodule that grows for a long time before resection. We describe a case of an 26-year-old man that presented with an enlarging nodule on his right eyelid. The histological findings revealed a hidradenoma papilliferum. So far, among the very few reports of ectopic hidradenoma papilliferum, only a very small number were localized to the eyelid.

    Introduction Primary ectopic craniopharyngiomas have only rarely been reported. Craniopharyngiomas involve usually the sellar and suprasellar region, but can be originated from cell remnants of the obliterated craniopharyngeal duct or metaplastic change of andenohypophyseal cells. We present the first case of a primary ectopic frontotemporal craniopharyngioma. Presentation of case A 35-year old woman presented with a one-year history of headache and diplopia. MRI showed a large frontotemporal cystic lesion. Tumor resection was performed with a keyhole endoscopic frontal lateral approach. The pathological features showed an adamantinomatous craniopharyngioma with a cholesterol granuloma reaction. Discussion There have been reported different localizations for primary ectopic craniopharyngioma. Our case presented a lobulated frontotemporal cystic mass formed by a dense eosinophilic proteinaceous material dystrophic calcifications and cholesterol crystals, with epithelial remnants. No tumor regrowth was observed in the magnetic resonance image 27 months postoperatively. Conclusion Primary ectopic craniopharyngioma is a rare entity with a pathogenesis that remains uncertain. This is an unusual anatomic location associated with unique clinical findings. PMID:25725331

    The purpose of this study was to assess and compare the changes in the SUV (standardized uptake value), the 18F-FDG (18F-fluorodeoxyglucose) uptake pattern, and the radioactivity level for the diagnosis of thyroid cancer via dual-time-point 18F-FDG PET/CT (positron emission tomographycomputed tomography) imaging. Moreover, the study aimed to verify the usefulness and significance of SUV values and radioactivity levels to discriminate tumor malignancy. A retrospective analysis was performed on 40 patients who received 18F-FDG PET/CT for thyroid cancer as a primary tumor. To set the background, we compared changes in values by calculating the dispersion of scattered rays in the neck area and the lung apex, and by comparing the mean and SD (standard deviation) values of the maxSUV and the radioactivity levels. According to the statistical analysis of the changes in 18F-FDG uptake for the diagnosis of thyroid cancer, a high similarity was observed with the coefficient of determination being R2 = 0.939, in the SUVs and the radioactivity levels. Moreover, similar results were observed in the assessment of tumor malignancy using dual-time-point. The quantitative analysis method for assessing tumor malignancy using radioactivity levels was neither specific nor discriminative compared to the semi-quantitative analysis method.

    Full Text Available INTRODUCTION Endogenous Cushing's syndrome is a clinical state resulting from prolonged, inappropriate exposure to excessive endogenous secretion of Cortisol and hence excess circulating free cortisol, characterized by loss of the normal feedback mechanisms of the hypothalamo-pituitary-adrenal axis and the normal circadian rhythm of cortisol secretion [2]. The etiology of Cushing's syndrome may be excessive ACTH secretion from the pituitary gland, ectopic ACTH secretion by nonpituitary tumor, or excessive autonomous secretion of cortisol from a hyperfunctioning adrenal adenoma or carcinoma. Other than this broad ACTH-dependent and ACTH-independent categories, the syndrome may be caused by ectopic CRH secretion, PPNAD, MAH, ectopic action of GIP or catecholamines, and other adrenel-dependent processes associated with adrenocortical hyperfunction. CASE REPORT A 31 year-old men with b-month history of hyperpigmentation, weight gain and proximal myopathy was refereed to Institute of Endocrinology for evaluation of hypercortisolism. At admission, patient had classic cushingoid habit with plethoric face, dermal and muscle atrophy, abdominal strie rubrae and centripetal obesity. The standard laboratory data showed hyperglycaemia and hypokaliemia with high potassium excretion level. The circadian rhythm of cortisol secretion was blunted, with moderately elevated ACTH level, and without cortisol suppression after low-dose and high-dose dexamethason suppression test. Urinary 5HIAA was elevated. Abdominal and sellar region magnetic resonance imaging was negative. CRH stimulation resulted in ACTH increase of 87% of basal, but without significant increase of cortisol level, only 7%. Thoracal CT scan revealed 14 mm mass in right apical pulmonary segment. A wedge resection of anterior segment of right upper lobe was performed. Microscopic evaluation showed tumor tissue consisting of solid areas of uniform, oval cells with eosinophilic cytoplasm and centrally

    11 per 1000 pregnancies are ectopic (NICE Guidelines, 2012) with 95 % of ectopic pregnancies being tubal in origin, and 80 % of these occurring within the ampulla (The Ectopic Pregnancy Trust). 5% therefore are non-tubal. In this review we aim to collate literature relevant to non-tubal ectopic pregnancy. Literature regarding cornual, ovarian, abdominal, interstitial, cervical and Caesarean scar ectopic pregnancy was reviewed using EMBASE and Medline databases. Non-tubal ectopic pregnancies are often overlooked, diagnosed late and are associated with higher maternal morbidity and mortality. Ultrasound remains the mainstay of diagnosis in corroboration with clinical features. Management may include medical treatment with methotrexate, surgery or expectancy. There is also an increasing interest in the use of minimally invasive radiological approaches. Non-tubal ectopic pregnancy is a rare but potentially life-threatening and often misdiagnosed condition. This is particularly pertinent for Caesarean scar ectopic pregnancies, the prevalence of which is increasing due to the rising proportion of women having Caesarean sections (Litwicka and Greco, 2011). Practitioners should be aware of non-tubal pregnancies to aid more efficient diagnosis, optimise management and increase patient safety.

  4. Papillary Thyroid Carcinoma in a Branchial Cleft Cyst without a Thyroid Primary: Navigating a Diagnostic Dilemma

    Directory of Open Access Journals (Sweden)

    Douglas S. Ruhl

    2013-01-01

    Full Text Available We report a rare case of papillary thyroid carcinoma incidentally found within a branchial cleft cyst. Only four other cases have been described in the literature. A total thyroidectomy and selective neck dissection was performed, and no evidence of occult primary disease was found after review of fine sections. Branchial cleft cysts are the most common lateral neck masses. Ectopic thyroid tissue within a branchial cleft cyst is an unusual phenomenon, and papillary thyroid carcinoma arising from this tissue is extremely rare. Clinicians are left with a diagnostic dilemma when presented with thyroid tissue neoplasm within a neck cyst in the absence of a thyroid primary—is this a case of metastatic disease with a missed primary or rather carcinoma arising in ectopic thyroid tissue? A thorough discussion of the etiologies of these lateral neck masses is reviewed including the embryogenesis of thyroid tissue in a branchial cleft cyst. The prognosis of patients with papillary thyroid carcinoma in lateral neck cysts without a primary site identified appears to be good following excision of the cyst and total thyroidectomy. Other management recommendations regarding these unique lateral neck malignancies are also presented.

    Intrathyroidal thymic tissue is rare and may be confused with a malignant thyroid nodule because of hyperechoic dots mimicking calcifications. We report the case of a thyroid nodule with malignant ultrasonographic findings in a 4-year-old child, which was confirmed cytologically as ectopic thymic tissue. The sonographic findings of ectopic thymus were similar to those of the thymus; therefore, clinicians should be familiar with ultrasonography findings of normal thymic tissue.

    Purpose: To study MR findings for clues to the diagnosis of lingual thyroid. Material and methods: MR findings and clinical and scintigraphic data of 5 cases of lingual thyroid were reviewed and the MR findings were compared to those of 16 cases of other submucosal lesions in the base of the tongue. Results: Four of the 5 patients with lingual thyroid were women and all had hypothyroidism. MR imaging depicted lingual thyroid in the midline in the base of the tongue (n=5) and additional ectopic thyroid glands in the floor of the mouth (n=2) or between the right and left sternohyoid muscles (n=1). Ectopic thyroid glands appeared isointense or hyperintense relative to muscle tissue on T1-weighted images and showed slight or fair contrast enhancement. All glands had low to intermediate T2 signal, which was also seen in 1 case of non-Hodgkin's lymphoma and 1 case of adenoid cystic carcinoma. All ectopic thyroid glands had well-defined margins, whereas malignant tumors tended to have ill-defined margins and to invade the surrounding structures. All but the 5 cases of lingual thyroid had an MR-demonstrable thyroid gland in the normal cervical position. Conclusion: A well-defined mass of low-intermediate T2 signal in the midline base of the tongue, neither with invasive tendency nor with a cervical thyroid gland in the normal site on MR imaging, may strongly indicate lingual thyroid.

    Ectopic pregnancy is a high-risk condition that occurs in 2% of reported pregnancies. This percentage is fivefold higher than that registered in the 1970s. Since 1970 there has been a two-fold increase in the ratio of ectopic pregnancies to all reported pregnancies in Hungary and in 2012 7.4 ectopic pregnancies per thousand registered pregnancies were reported. Recently, the majority (80%) of cases can be diagnosed in early stage, and the related mortality objectively decreased in the past few decades to 3.8/10,000 ectopic pregnancies. If a woman with positive pregnancy test has abdominal pain and/or vaginal bleeding the physician should perform a work-up to safely exclude the possibility of ectopic pregnancy. The basis of diagnosis is ultrasonography, especially vaginal ultrasound examination and measurement of the β-subunit of human chorionic gonadotropin. The ultrasound diagnosis is based on the visualization of an ectopic mass rather than the inability to visualize an intrauterine pregnancy. In some questionable cases the diagnostic uterine curettage or laparoscopy may be useful. The actuality of this topic is justified by practical difficulties in obtaining correct diagnosis, especially in the early gestational time.

    Ectopic pregnancy remains a leading cause of maternal mortality and accounts for a sizeable proportion of infertility and ectopic recurrence. The possibility that a woman is experiencing an ectopic pregnancy must be considered when evaluating a woman, especially a sterilized woman, who has a possible pregnancy, amenorrhea, abdominal pain, or abnormal bleeding; studies have found that one in six pregnancies occurring after tubal sterilization are ectopic. The authors present a clinical study of 82 cases of ectopic pregnancy admitted to the department of Obstetrics and Gynecology of Mahatma Gandhi Institute of Medical Sciences, Sevagram. Cases of ectopic pregnancy represent 0.99% of total obstetric admissions, of whom 69.51% were diagnosed as such on admission. 40.24% of the women were older than 30 years, while 34.14% were elderly beyond third parity. 70.73% of the women presented before missing their second period. Patients presented with multiple complaints, but the most common was abdominal pain reported by 61.70%. 78.04% were admitted with an acute abdomen, but shock was present in only 7.14% of cases. The main surgical treatment modality was salpingectomy among 59.75%. There was no maternal mortality through postoperative morbidity in the form of paralytic ileus, although fever did occur in some women.

    Full Text Available An ectopic pregnancy is one in which fertilized ovum is implanted at the site other than normal uterine cavity.[1] Incidence of ectopic pregnancy is 1:160 deliveries.[2] Clinical presentation is variable from acute to chronic type. Due to its varied clinical presentation ectopic pregnancy poses great diagnostic difficulty both to obstetrician, physician and surgeons.[3] OBJECTIVE: To find out incidence in our study population and to evaluate symptomatically and clinical presentation in these patients. MATERIALS AND METHODS: Retrospective study of 34 ectopic pregnancies admitted and treated in Medical College hospital, Ujjain from 2010 to 2015 are included in the study. RESULTS: The incidence of ectopic pregnancy is more between the age group of 21-30years (73.52% and in Multigravida 64.71%. Infertility and previous tubal surgery are the high risk factors for tubal pregnancy. Pain in abdomen was present in all 34 cases, amenorrhea in 97.05% and bleeding per vagina in 76.47% cases. Syncopal attacks, vomiting were detected in 14.70% cases. Acute ectopic pregnancy was detected in 14.71% and chronic in 85.29% cases. 82.35% cases presented with adnexal mass, 79.41% with cervical motion tenderness, 50% with pallor, 32.35% with abdominal lump and tenderness and 11.76% with fullness in POD. CONCLUSION: Ectopic pregnancy is leading cause of maternal mortality in first trimester. In spite of advanced diagnostic techniques. It poses great diagnostic difficulties due to varied signs and symptoms. Previous tubal surgery pelvic inflammatory disease and infertility are the risk factors of tubal pregnancy.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

  9. Lingual Thyroid Excision with Transoral Robotic Surgery

    Directory of Open Access Journals (Sweden)

    Elif Ersoy Callıoglu

    2015-01-01

    Full Text Available Ectopic thyroid gland may be detected at any place between foramen caecaum and normal thyroid localization due to inadequacy of the embryological migration of the thyroid gland. It has a prevalence varying between 1/10.000 and 1/100000 in the community. Usually follow-up without treatment is preferred except for obstructive symptoms, bleeding, and suspicion of malignity. Main symptoms are dysphagia, dysphonia, bleeding, dyspnea, and obstructive sleep apnea. In symptomatic cases, the first described method in surgical treatment is open approach since it is a region difficult to have access to. However, this approach has an increased risk of morbidity and postoperative complications. Transoral robotic surgery, which is a minimally invasive surgical procedure, has advantages such as larger three-dimensional point of view and ease of manipulation due to robotic instruments. In this report, a case at the age of 49 who presented to our clinic with obstructive symptoms increasing within the last year and was found to have lingual thyroid and underwent excision of ectopic thyroid tissue by da Vinci surgical system is presented.

  10. Thyroid Follicle Formation and Thyroglobulin Expression in Multipotent Endodermal Stem Cells

    Latif, Rauf; Davies, Terry F.

    2013-01-01

    Objective The aim of this study was to assess the impact of transcriptional induction on thyroid follicular cell (TFC) differentiation from endodermally matured embryonic stem (ES) cells. The thyroid transcription factors—NKx2 homeobox 1 (NKx2-1, formerly called TTF-1) and Paired box gene 8 (Pax8)—are known to associate biochemically and synergistically in the activation of thyroid functional genes including the sodium/iodide symporter (NIS), thyrotropin (TSH) receptor (TSHR), thyroglobulin (Tg), and thyroid peroxidase (TPO) genes. In this study, we investigated the ability of ectopically expressed Pax8 and NKx2-1 to further the induction and differentiation of murine ES cells into potential TFCs. Methods ES cells were stably transfected with either the Pax8 gene, the NKx2-1 gene, or both genes to study the induction of NIS, TSHR, Tg, and TPO genes as assessed using both quantitative reverse-transcription polymerase chain reaction (qRT-PCR) and protein expression. The derived cells were cultured with or without the presence of activin A to allow their differentiation into multipotent endodermal cells. Results The four thyroid-specific genes NIS, TSHR, Tg, and TPO were all significantly activated by expressing both transcription factors within the same ES cell. In contrast, significant but much lower transcriptional activity of the TSHR, Tg, and TPO genes was detected in cells expressing just NKx2-1, and only the NIS and TSHR genes responded to Pax8 alone. No Tg protein expression could be detected prior to their development into endodermal derivatives. However, after further differentiation of postembryoid body ES cells with activin A and TSH into endodermal cell lines, those cells with dual transfection of Pax8 and NKx2-1 demonstrated greatly enhanced expression of the NIS, TSHR, Tg, and TPO genes to such a degree that it was similar to that found in control thyroid cells. Furthermore, these same cells formed three-dimensional neofollicles in vitro and

  11. Sublingual thyroid ectopy: similarities and differences with Kallmann syndrome.

    Van Vliet, Guy; Deladoëy, Johnny

    2015-01-01

    Permanent primary congenital hypothyroidism (CH), the commonest cause of preventable intellectual disability, is due to defects in the embryonic development of the thyroid in the vast majority of cases. These defects are collectively called thyroid dysgenesis. The thyroid may be absent (athyreosis) but, more commonly, a sublingual thyroid ectopy without lateral lobes, is the only thyroid tissue present. Such an ectopy presumably results from an arrest in the downward migration of the median anlage. Thyroid ectopy almost always occurs in a sporadic fashion. However, first-degree relatives are affected more often than chance alone would predict. On the other hand, almost all reported monozygotic twin pairs are discordant for thyroid ectopy. Current research is aimed at reconciling these contradictory epidemiological data. We propose a two-hit mechanism associating a germline predisposing factor with another genetic or epigenetic alteration within the ectopic thyroid tissue itself or, as in some forms of Kallmann syndrome, in the structures surrounding the thyroid during embryogenesis. Thyroid ectopy, a model for sporadic congenital malformations in humans, is also associated with congenital heart disease, and molecular mechanisms common to thyroid and heart development are being unraveled.

    Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

    Full Text Available In addition to the subcutaneous and the visceral fat tissue, lipids can also be stored in non-adipose tissue such as in hepatocytes (intrahepatocellular lipids; IHCL, skeletal (intramyocellular lipids; IMCL or cardiac muscle cells (intracardiomyocellular lipids; ICCL. Ectopic lipids are flexible fuel stores that can be depleted by physical exercise and repleted by diet. They are related to obesity and insulin resistance. Quantification of IMCL was initially performed invasively, using muscle biopsies with biochemical and/or histological analysis. 1H-magnetic resonance spectroscopy (1H-MRS is now a validated method that allows for not only quantifying IMCL non-invasively and repeatedly, but also assessing IHCL and ICCL. This review summarizes the current available knowledge on the flexibility of ectopic lipids. The available evidence suggests a complex interplay between quantitative and qualitative diet, fat availability (fat mass, insulin action, and physical exercise, all important factors that influence the flexibility of ectopic lipids. Furthermore, the time frame of the intervention on these parameters (short-term vs. long-term appears to be critical. Consequently, standardization of physical activity and diet are critical when assessing ectopic lipids in predefined clinical situations.

    Ectopic endometriosis is a common condition which is often underdiagnosed, where MRI can help make a diagnosis simply, non-invasively and without irradiation. However, imagery signs of it are enormously polymorphic with a wide range of possible locations. In this paper, we have tried to illustrate comprehensively all its MRI appearances depending on the different locations where it occurs.

    The aim of this study was to determine the risk factors of ectopic pregnancy in cases presented to the Woman's Health Hospital (WHH) in Assuit University, and to perform clinical audit on strategies for management of ectopic pregnancy in the WHH. This descriptive hospital based study was conducted at the Woman's Health Hospital (WHH) of Assuit University (Egypt). There were 210 patients who were admitted to the WHH with the diagnosis of ectopic pregnancy in the period between February 1, 2015 through the end of October 2015. Data were analyzed by SPSS version 21, using descriptive statistics, Mann-Whitney U test, and Chi square. Ectopic pregnancy affects woman in the reproductive age. There are many risk factors that increase the chance of its occurrence; however, it may also occur in the absence of any risk factors (14.0%). Internal VD (72.5%) is the most frequent risk factor; other risk factors include history of abortion, previous CS, ovulation induction, history of infertility, or previous history of EP. Clinical audit is an important item of any adequate health care. As regards to the clinical audit of EP management, we are not adhering to the guidelines.

    Full Text Available Lingual thyroid is a rare embryological anomaly originated from the thyroid gland failure that descends from the foramen cecum to its normal eutopic pre-laryngeal site. The case in this study was a 39 year old female, presenting with the sensation of a foreign body, progressive dysphagia and dyspnea. Indirect laryngoscopy revealed a large well-defined mass in the tongue base. Imaging studies confirmed the diagnosis of large ectopic lingual thyroid. The surgery was performed via an external cervical approach due to the mass size. The decision on the best treatment looks into the mass position, size, symptoms, airway emergency and medical facilities.

  19. Mechanisms of Ectopic Gene Conversion

    Directory of Open Access Journals (Sweden)

    P.J. Hastings

    2010-11-01

    Full Text Available Gene conversion (conversion, the unidirectional transfer of DNA sequence information, occurs as a byproduct of recombinational repair of broken or damaged DNA molecules. Whereas excision repair processes replace damaged DNA by copying the complementary sequence from the undamaged strand of duplex DNA, recombinational mechanisms copy similar sequence, usually in another molecule, to replace the damaged sequence. In mitotic cells the other molecule is usually a sister chromatid, and the repair does not lead to genetic change. Less often a homologous chromosome or homologous sequence in an ectopic position is used. Conversion results from repair in two ways. First, if there was a double-strand gap at the site of a break, homologous sequence will be used as the template for synthesis to fill the gap, thus transferring sequence information in both strands. Second, recombinational repair uses complementary base pairing, and the heteroduplex molecule so formed is a source of conversion, both as heteroduplex and when donor (undamaged template information is retained after correction of mismatched bases in heteroduplex. There are mechanisms that favour the use of sister molecules that must fail before ectopic homology can be used. Meiotic recombination events lead to the formation of crossovers required in meiosis for orderly segregation of pairs of homologous chromosomes. These events result from recombinational repair of programmed double-strand breaks, but in contrast with mitotic recombination, meiotic recombinational events occur predominantly between homologous chromosomes, so that transfer of sequence differences by conversion is very frequent. Transient recombination events that do not form crossovers form both between homologous chromosomes and between regions of ectopic homology, and leave their mark in the occurrence of frequent non-crossover conversion, including ectopic conversion.

    Myasthenia gravis is the most common disease associated with thymoma, but it is rarely accompanied by ectopic thymoma. We describe a 47-year-old woman who presented with an ectopic cervical thymoma with myasthenia gravis. She was admitted to our neurology department with ptosis, diplopia, and mandibular muscle fatigue, and was diagnosed with myasthenia gravis. The mass was located posterior to the right lobe of thyroid gland on computed tomography and was diagnosed as ectopic thymoma on fine-needle aspiration biopsy examination. Transcervical excision of thymoma and VATET were performed. The patient has been free of neurological symptoms and has displayed no evidence of recurrent thymoma for 2 years.

    2014-12-01

    Full Text Available Ectopic thyroid tissue is a rare pathology of the thyroid that is formed by the abnormal migration of the thyroid tissue. It is seen once in about every 100.000 to 300.000 births and is generally asymptomatic. Asymptomatic ectopic thyroid tissue may grow larger and become symptomatic in the form of a neck mass due to thyroid tissue hyperplasia. The thyroid gland, apart from its normal localization before the trachea, may lie between the tongue root and the trachea generally on the middle line at any level. A 71-year-old male patient presented to our ear- nose and throat clinic with a mass of 5x4x3 cm located in the right carotid triangle. The thin-needle aspiration biopsy specimen was reported as thyroid tissue and subsequently the mass was excised under general anesthesia.  The histopathological evaluation of the mass revealed that it was an atypically located ectopic thyroid nodule. No complications were seen within one year follow-up of the patient.

    Full Text Available Background: The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. Materials and Methods: This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. Results: A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09% patients, Cryptococcus neoformans in 11 (7% patients and cytomegalovirus in 3 (2% patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01% patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients, interstitial fibrosis in thyroid (7 patients, and calcification in thyroid (8 patients. Conclusions: Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

    The key to uncovering the etiology of hyperthyroidism lies in a careful history and physical examination. Autoimmune markers provide additive information, but should not solely be used to make a diagnosis. Concern has been raised that the overzealous use of thyroid ultrasound, following abnormal thyroid function tests, diverts attention from the workup of the biochemical abnormality to the workup of an incidentally found thyroid nodule. If further imaging is needed, the use ofathyroidscanhas been suggestedbythe Endocrine Society and the American Association of Clinical Endocrinologists. However, in certain scenarios, this may be contraindicated. We present the case of a 28-year-old female with hyperthyroidism, as aplatform to discuss an important clinical sign present on Doppler ultrasound of the thyroid. By recognizing the clinical information gained from a Doppler ultrasound, physicians can avoid additional invasive workup and apply the use of ultrasound where most appropriate.

    2015-01-01

    Full Text Available Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of thyroid gland fails to develop. It is much rarer in males. There is a higher incidence of associated thyroid disorders in patients with thyroid hemiagenesis; therefore early and prompt diagnosis is important for children. We present the ultrasonographic and scintigraphic findings of thyroid hemiagenesis in an eight-year-old-boy. On ultrasonography (US, left lobe of the thyroid gland could not be demonstrated and the right lobe showed minimal hyperplasia. Its echogenicity was normal and no nodule was seen. On thyroid scintigraphy, left lobe of thyroid gland or any ectopic thyroid tissue could not be demonstrated, while the right lobe showed minimal hyperplasia. Without performing any invasive procedure, we enrolled the child in a follow-up program with the guidance of US and scintigraphy, which were effective both in making the final diagnosis of thyroid hemiagenesis and in evaluating the current status of the present thyroid tissue. In conclusion, if only one thyroid lobe is detected in a pediatric case initially with US or scintigraphy, the diagnosis of thyroid hemiagenesis should be suggested and, before any unnecessary or invasive attempt, the other complementary method (scintigraphy/US should be performed.

    Full Text Available Background: The blastocyst implantation in any place other than uterus cavity endometrium is called ectopic pregnancy. The prevalence of ectopic pregnancy is different in various countries. This study has been conducted to investigate the epidemiology of ectopic pregnancy in Hamadan province during 2000-2010.Materials and Methods: The present study is a retrospective descriptive study. The data on 872 ectopic pregnancies were extracted by questionnaires from the files in the records department of hospitals and delivery centers in Hamadan province during 2000-2010. Data were analyzed using descriptive statistics and the obtained data were analyzed using SPSS-16 software.Results: The frequency of ectopic pregnancy in Hamadan province during 2000-2010 was averagely 2.6 per 1000 pregnancies. Tubal pregnancy with 95.2% is the most prevalent type of ectopic pregnancy most of which had occurred in the right tube (52.4%. Most ectopic pregnancies (52.2% were in the age group of 25-34.Conclusion: The prevalence of ectopic pregnancy in Hamadan province during the mentioned years has been 2.6 in 1000 pregnancies, which is lower compared to many existing data. However, the prevalence of ectopic pregnancy in this province has increased over time, so that it has become 3.3 times as much from 2000-2010.

    Ectopic eruption of a tooth within the dentate region of the jaws is often noticed in clinical practice and is well documented in the literature. But the ectopic eruption into the non dentate region is rare and scantly documented. The maxillary sinus is one such a non dentate region, apart from nasal septum, mandibular condyle, coronoid process and the palate, to accommodate such ectopic eruptions of teeth. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature and discussed. Early surgical intervention for removal of ectopic tooth along with enucleation of the associated cyst, if any, is the treatment of choice.

    2011-12-01

    Full Text Available Abstract Introduction We report the case of a patient diagnosed with a struma ovarii with lymphocytic thyroiditis of her ectopic thyroid tissue. We believe that this case presents an unusual variation of a struma ovarii and a rare presentation of subclinical hyperthyroidism. Case presentation A 17-year-old Caucasian female patient who had undergone an ovariectomy and been diagnosed with a struma ovarii was subsequently found to have persistent subclinical hyperthyroidism with a low radioiodine uptake. Abdominal magnetic resonance imaging and iodine-131 whole body scanning showed no residue or recurrence and a thyroid ultrasonography was normal. Laboratory and histopathological findings suggested Hashimoto's thyroiditis as the cause of the subclinical thyrotoxicosis, which had presumably started at the ectopic tissue. Conclusion Struma ovarii is a rare cause of thyrotoxicosis, and can be difficult to diagnose in the presence of co-existing thyroid disorders. In patients with a struma ovarii who have not undergone thyroidectomy, there is no common consensus on management in terms of residue, recurrence or metastasis. Autoimmune thyroiditis must be kept in mind for a differential diagnosis.

    The management of ectopic pancreas is not well defined. This study aims to determine the prevalence of symptomatic ectopic pancreas and identify those who may benefit from treatment, with a particular focus on robotically assisted surgical management. Our institutional pathology database was queried to identify a cohort of ectopic pancreas specimens. Additional clinical data regarding clinical symptomatology, diagnostic studies, and treatment were obtained through chart review. Nineteen cases of ectopic pancreas were found incidentally during surgery for another condition or found incidentally in a pathologic specimen (65.5%). Eleven patients (37.9%) reported prior symptoms, notably abdominal pain and/or gastrointestinal bleeding. The most common locations for ectopic pancreas were the duodenum and small bowel (31% and 27.6%, respectively). Three out of 29 cases (10.3%) had no symptoms, but had evidence of preneoplastic changes on pathology, while one harbored pancreatic cancer. Over the years, treatment of ectopic pancreas has shifted from open to laparoscopic and more recently to robotic surgery. Our experience is in line with existing evidence supporting surgical treatment of symptomatic or complicated ectopic pancreas. In the current era, minimally invasive and robotic surgery can be used safely and successfully for treatment of ectopic pancreas.

  19. Concurrent bilateral ectopic pregnancy: a rarity

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    2015-01-01

    The association of Hashimoto's thyroiditis and thyroid cancer remains an active focus of research and controversy. Since it was first proposed in 1955, numerous studies have explored the epidemiology and etiology of these concurrent disease processes. The lymphocytic infiltration of Hashimoto's thyroiditis is frequently encountered in thyroid glands resected for a neoplasm. The most frequent association is noted with papillary thyroid cancer. Several recent studies performed on patients undergoing thyroidectomy with coexisting Hashimoto's thyroiditis report an increased prevalence of papillary thyroid cancer, with a favorable disease profile and an improved prognosis, particularly in women. Conversely, some population-based studies using fine-needle aspiration biopsy data report no linkage between serologic Hashimoto's thyroiditis and thyroid cancer, yet they are limited by the lack of definitive pathology. On the other hand, the significantly increased incidence of primary thyroid lymphomas in patients with Hashimoto's thyroiditis strongly suggests a pathogenetic link between this autoimmune disorder and malignant thyroid lymphoma. The lymphocytic infiltration of Hashimoto's thyroiditis is frequently associated with papillary thyroid cancer and may indeed be a risk factor for developing this type of cancer. Nonetheless, a pathogenesis linking these diseases remains unclear. The relationship between thyroid lymphoma and Hashimoto's thyroiditis appears to be well established.

    Full Text Available Ectopic pregnancies occur in approximately 1.4% of all pregnancies and account for 15% of pregnancy-related deaths. Considering the high degree of mortality, recognizing an ectopic pregnancy is important. Signs and symptoms of an ectopic pregnancy are nonspecific and include pain, vaginal bleeding, and an adnexal mass. Therefore, imaging can play a critical role in diagnosis. There are different types of ectopic pregnancies, which are tubal, cornual, cesarean scar, cervical, heterotopic, abdominal, and ovarian. Initial imaging evaluation of pregnant patients with pelvic symptoms is by ultrasonography, transabdominal, transvaginal or both. We review the sonographic appearance of different types of ectopic pregnancies that will aid in accurate and prompt diagnosis.

    This retrospective cohort study reviewed the diagnosis of all ectopic pregnancies within a district general hospital over a 5-year period after the establishment of a dedicated Early Pregnancy Assessment Unit (EPAU). Of 215 ectopic pregnancies identified, notes were available for 208 (97%). Two-hundred and two cases were determined to have been diagnosed and managed as ectopic pregnancies. Six cases were excluded as they were pregnancies of unknown location managed as such. Overall, 91% were diagnosed by ultrasound scan, 5% were diagnosed clinically and 3% were diagnosed on serial human chorionic gonadotrophin (hCG) levels. This study found that the introduction of a dedicated, multi-professional, EPAU with a stable workforce improved ultrasound visualisation of ectopic pregnancies at first ultrasound scan from 22% prior to its commencement, to 61% over this period. The improvement in positive scan diagnosis of ectopic pregnancy was associated with a reduction in negative laparoscopy rate from 13% to 6%.

Rarer is the presence of multiple ectopic teeth involving both the maxillary incisors and canine and has not been reported yet. Method: A seventeen year old male presented with a complaints of dull pain on the right side of the face for past two years. Water’s view X-ray of PNS revealed dense non-specific opacification of the right maxillary sinus. Result: Antrostomy through Caldwell–Luc approach revealed three ectopic teeth in the right maxillary sinus. Later the teeth were identified to be central incisor, lateral incisor and canine. Conclusion: Rare finding of ectopic incisors in the maxillary sinus is reported and the need for interdisciplinary approach to patients is stressed upon.

The aim of this study is to report a case of ovarian ectopic pregnancy Case presentation: A 19 years old woman, with a history of polycystic ovary, first pregnancy, gestation age 9 weeks and 4 days, visited the doctor. She was complaining of severe abdomen pain and vaginal spotting and she was bedridden because of threatened miscarriage. She had discharged from hospital with progesterone suppository prescription. Requesting a transvaginal ultrasound and heterogeneous echogenic mass (size18×8/5 was shown near the left ovary. It was shown as ectopic pregnancy. The patient was hospitalized by ectopic pregnancy in ovary diagnosis and she was treated by methotrexate. Conclusion: In pregnant women that complain of bleeding and spotting in early pregnancy, in addition to threatened abortion, ectopic pregnancy should exist even in the absence of clinical symptoms, should be considered.

    Ectopic thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are rare and can often be misdiagnosed as primary hyperthyroidism. We present a case of an ectopic suprasellar TSH-secreting pituitary adenoma. A literature review of previously reported ectopic TSH-secreting and suprasellar pituitary adenomas is included to illustrate the clinical characteristics of this disease entity and the diversity of operative approaches to treating ectopic suprasellar pituitary adenomas. A 46-year-old man presented with typical clinical signs of hyperthyroidism and a history of progressive visual field impairment and vision loss. Laboratory investigations revealed that the patient had elevated levels of free thyroxine and free triiodothyronine and a normal level of TSH. Neuro-ophthalmologic examination showed right eye/left eye = 1.0/0.6 and left temporal hemianopia. Magnetic resonance imaging revealed a mass located in the suprasellar space. The patient underwent preoperative short-term octreotide treatment followed by gross total resection of the tumor via the extended endoscopic endonasal transtuberculum sellar approach. At 6-month follow-up evaluation, the patient's endocrinologic function tests met the criteria for cure, and magnetic resonance imaging revealed a normal pituitary gland and stalk with no tumor recurrence. Histologic diagnosis confirmed the presence of a TSH-secreting pituitary adenoma. To the best of our knowledge, this is the first reported case of an ectopic suprasellar TSH-secreting pituitary adenoma. Preoperative preparation and complete resection are the keys to a cure. The extended endoscopic endonasal transtuberculum sellar approach is an alternative minimally invasive method for the removal of an ectopic suprasellar pituitary adenoma.

    During the last decades the incidence of ectopic pregnancy has been steadily rising. The chosen therapy has usually been unilateral salpingectomy. Recently, different conservative (tube-preserving) treatment-modalities have been introduced in clinical practice. We have tried conservative treatment by local injection of prostaglandin F2a (total dose 2-4 mg) directly into the tubal pregnancy and, if feasible, also into the corpus luteum graviditate. The treatment was successful in 13 out of 16 patients. In one patient laparotomia was performed because of pain, and revealed a haematoma in fossa Douglasi. Reinjection of prostaglandin was necessary in one patient because of rising HCG titres. One patient was hospitalized for four days because of nausea and pain. The treatment was otherwise successful. The method may be useful as a non-surgical alternative in haemodynamically stable patients without tubal rupture. Further studies are needed to evaluate the outcome in terms of future fertility.

    @@ Papillary thyroid carcinoma (PTC) is the most common type of well-differentiated thyroid cancer and is considered to be a relatively indolent tumor in which distant metastasis and death are rare.1 The metastasis of PTC is usually to regional lymph nodes, especially the cervical and mediastinal nodes. Metastases to the brain are rare, and constitute 0.1%-5.0% of distant metastases of papillary carcinoma.2 Skull metastasis is uncommon,and is found in 2.5%-5.8% of cases of thyroid cancer.3 Skull base metastasis of PTC is extremely rare, with only eight reported cases in the literature involving the clivus,cavernous sinus, sella turcica, and the petrous apex and ridge.4 A metastatic lesion can arise from histologically benign and silent thyroid neoplasms,5 and differential diagnosis between ectopic and metastatic thyroid cancer can be difficult,6 therefore, the management of thyroid cancer is controversial after removal of metastatic disease.Here we reported a case of papillary thyroid microcarcinoma (PTMC) that was manifested as a solitary clivus metastasis and discussed the diagnostic and therapeutic management strategies. The 73-year-old patient presented with visual impairment in the right eye,and epistaxis. The patient subsequently underwent complete total thyroidectomy after a diagnosis of papillary microcarcinoma. This finding emphasizes that clinically significant metastases can arise from thyroid papillary microcarcinoma. Total thyroidectomy and careful review of the histology are necessary to prevent delay in proper diagnosis.

    Approximately 2.1% to 8.6% of all pregnancies after IVF with embryo transfer have been reported to be ectopic. In this report, we present a case of presumed intestinal microperforation caused by an ectopic pregnancy following IVF. A 29-year-old woman presented with rectal bleeding. She had previously been treated for an ectopic pregnancy for which she had received two doses of methotrexate. Colonoscopy and abdominal CT angiography were performed and showed that the ectopic pregnancy was attached to the sigmoid colon. Surgery was performed to remove the ectopic pregnancy. Because intestinal microperforations were suspected, the patient received intravenous antibiotic therapy during her hospitalization. In cases of intestinal bleeding, clinicians should consider the possibility of intestinal involvement of an ectopic pregnancy, even if the response to treatment for the ectopic pregnancy has been appropriate.

    Ectopic parathyroid adenomas are considered the main cause of primary hyperparathyroidism. However, concurrent parathyroid and thymic pathologies are rarely diagnosed in the same patient. A 47-year-old man with history of diabetes mellitus, hypertension, and myasthenia gravis presented with persistent hypercalcemia. Laboratory investigations, computed tomography, and technetium-99 m sestamibi scintigraphy revealed ectopic parathyroid glands, a mediastinal mass, and an enlarged thymus. The patient underwent thymectomy and mass excision via a median sternotomy. Histopathology was consistent with ectopic parathyroid adenoma and thymolipoma.

    To evaluate the benefit of adding a pertechnetate parathyroid scan (dual-isotope imaging) in the interpretation of sestamibi dual-phase parathyroid scintigraphy. One hundred and sixteen dual Tc-99m sestamibi (MIBI) and Tc-99m pertechnetate subtraction parathyroid studies, performed between January 2000 and February 2006, were retrospectively reviewed. Dual-phase technetium sestamibi examinations were initially interpreted, with blinding to the technetium pertechnetate findings. Subsequently, technetium pertechnetate scan findings were added, and changes in interpretation were recorded. By adding Tc-99m pertechnetate imaging, the interpretation of 17 scans (17/116=14.6%) was substantially altered. This included 5 scans (4%) that changed from negative to positive and 9 scans (8%) that changed from equivocal to positive, excluding ectopic tissue and directing minimally invasive surgery, without the need for further imaging, such as ultrasound, in 12% of cases. One examination changed from positive to negative. In addition, 2 scans changed from equivocal to negative, necessitating further preoperative imaging for the evaluation of additional pathology such as thyroid nodules and lymph nodes and the consideration of hyperplasia. Among the remaining 99 patients, Tc-99m pertechnetate scans may also have contributed to the diagnosis in the 66 positive Tc-99m MIBI scans by increasing confidence in the interpretation and obviating additional imaging. Ten cases remained equivocal. By adding Tc-99m pertechnetate imaging, scan interpretation was changed in 14.6% of cases, and interpretation confidence was enhanced in all but 10 remaining equivocal cases. The addition of a dual-isotope subtraction also eliminated the need for additional testing, such as ultrasound, in 12% of our cases. Increased confidence in interpretation that comes with dual-isotope subtraction may come at the cost of slight lengthening of imaging time but likely simplifies preoperative localization and

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    Full Text Available Ectopic pregnancy (implantation anywhere outside the normal uterine cavity is the most common pregnancy complication leading to mortality. In the era of artificial reproductive techniques and liberated life style, ectopic pregnancy is not rare. However, ovarian pregnancy is an uncommonly encountered variety of ectopic pregnancy, and a definitive preoperative diagnosis is very challenging. Intraoperative findings and histopathology usually provide the final diagnosis. High serum beta human chorionic gonadotrophin levels, lack of an intrauterine gestational sac, tubo ovarian mass on ultrasonography (USG, patient’s risk factors, in addition to the Spiegelberg’s criteria gives a high probability of ovarian pregnancy. Management with surgical approach is required in all cases. We have made an attempt to present a case of ovarian pregnancy, consistent with Spiegelberg’s criteria. Our case demonstrates the difficulty in preoperative and intra operative diagnosis of ovarian ectopic, the final confirmation has been made by histopathology.

    Embryo in uterine implantation is a complex and multifactor-related process and is a downstream and ideal point for woman fertility control.Understanding the cellular and molecular mechanism of implantation is a prerequisite for development of anti-implantation contraceptives.In spite of considerable accumulation of information from the laboratory animals that has been achieved,it is difficult to generate such information in human due to ethical restriction and experimental limitation,and the present knowledge for understanding the definitive mechanisms which control these events remains elusive.Embryo implantation can also occur outside uterus.Some women with abdominal pregnancies could successfully complete the processes of gestation and bear normal babies,implying that implantation itself may be not an endometrium-specific process.Reproductive biologists should cooperate with gynecologists to further comparatively study the molecular and cellular mechanisms of implantation normally occurring in endometrium and abnormally appearing outside uterine cavity.Such collaborative studies may generate new important information for developing anti-implantation contraceptive and for techniques of accurate diagnosis of ectopic pregnancy.A specially designed GnRH-2 analog and a combination use of Iow dose RU486 and gossypol as anti-implantation contraceptives have been suggested.

    Ectopic pregnancy (EP), in which a fertilized ovum implants outside the uterine cavity, is the leading cause of pregnancy-related death in the first trimester. EP is usually suspected by a positive pregnancy test and an empty uterus on transvaginal sonography (TVS). Although TVS is the initial modality of choice, it may occasionally fail to demonstrate the implantation site. When TVS findings are indeterminate, magnetic resonance imaging (MRI) may provide better delineation of the focus of EP owing to its excellent tissue contrast. The key MRI features of EP include gestational sac (GS)-like structures that typically appear as a cystic sac-like structure, frequently associated with surrounding acute hematoma of distinct low intensity on T2-weighted images. In tubal pregnancy, an enhanced tubal wall on postcontrast images may be another diagnostic finding. Ruptured EP is inevitably associated with acute hematoma outside these structures. In intrauterine EP, recognition of the relationship between GS-like structure and the myometrium can aid in differentiating from normal pregnancy. Diagnostic pitfalls include heterotopic pregnancy, decidual changes in endometrial cyst and theca lutein cysts mimicking GS-like structures. Knowledge of a spectrum of clinical and MRI features of EP is essential for establishing an accurate diagnosis and determining appropriate management. (orig.)

    Ectopic liver tissue can develop at various sites near the liver. Ectopic hepatocellular carcinomas (HCCs) arising from ectopic liver tissue have a rare clinical incidence. A very rare case has been observed to have metastasis after operation. We report an extremely rare case with multiple masses which were identified in the head and body of the pancreas. Ectopic hepatocellular carcinomas. The masses were removed by surgical resection. Histopathological analysis showed that both masses were ectopic HCC. The patient was still alive and did not have metastasis and relapse. The literature review for this rare case is also presented to highlight the risk of ectopic HCC and good prognosis of operation for ectopic HCC.

    Ectopic pregnancies are a serious gynaecological emergency that can be fatal. As such, prompt diagnosis and safe timely treatment is essential. Here, we review the literature on the development of molecularly targeted diagnostics and therapeutics for ectopic pregnancy. A blood-based biomarker that accurately identifies an ectopic pregnancy could be used to offer early diagnostic certainty in cases where ultrasound cannot determine the location of the embryo ('a pregnancy of unknown location'). Molecules examined so far can be broadly grouped into biological themes of relevance to reproduction: (i) Fallopian tube (dys)function, (ii) embryo/trophoblast growth, (iii) corpus luteum function, (iv) inflammation, (v) uterine function and (vi) angiogenesis. While a sensitive and specific biomarker for ectopic pregnancy has yet to be identified, it is possible that improvements in platform technologies or a multi-modal biomarker approach may yield an accurate diagnostic biomarker test. Furthermore, with the advent of better imaging technology, the need for a blood-based biomarker test may be superseded by improvements in ultrasound or magnetic resonance imaging technology. There have been some recent preclinical studies describing molecularly targeted therapeutic approaches for ectopic pregnancy. Notably, bench-to-bedside studies have examined the use of combination gefitinib (orally available epidermal growth factor receptor inhibitor) and methotrexate. Preclinical studies suggest that combination gefitinib and methotrexate is highly effective in inducing placental cell death, and is significantly more effective than methotrexate alone. In early human trials, encouraging preliminary efficacy data have shown that combination gefitinib and methotrexate can rapidly resolve tubal ectopic pregnancies, and large extra-tubal ectopic pregnancies. If a large clinical randomized controlled trial confirms these findings, combination gefitinib and methotrexate could become a new

    Ectopic eruption of teeth into a region other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar tooth that caused chronic purulent sinusitis in relation to the right maxillary sinus.

    Arrhythmia is a condition in which an additional ectopic pacemaker is present in the tissue of the heart. Localization of ectopic foci is essential for successful radio-frequency ablation, an important surgical way of treating arrhythmia. In one of the possible mechanisms, arrhythmia induced by an ectopic foci located in one of the main blood vessels leading out or onto the heart. The therapeutic procedure in this case is usually ablation of the whole junction of the blood vessel with heart wall. In this way, whatever excitation occurs inside the vessel, it cannot penetrate the ventricles perturbing their contraction cycle. Such an ablation procedure is long and burdened with the risk of the perforation. A more safe method would involve the localization of the source of the excitation (i.e. the ectopic foci) and its ablation. The methods used in cardiology at present involve complicated localization systems and are time-consuming with the patient spending a long time on the operating table. Recently, Hall and Glass have developed numerical methods which allow to quickly to model the localization of the ectopic foci in a flat, square sample of an inhomogeneous medium. Here, we demonstrate an extension of this model for the case of a cylinder containing an ectopic foci, that can be a model of a blood vessel with the source of the ectopic beat inside it. Three methods of localization are implemented. Standard electrodes containing several active tips are used to stimulate the medium locally and locate the foci judging from the reaction of the system. The first one uses electrode activation times to compute the location of the ectopic site. The second one localizes it by measuring the resetting response of the foci, and the third one, uses wavefront curvature. Specifically for the cylindrical geometry of the blood vessel, we developed a localization procedure that allows to quickly localize the pacemaker.

    Conclusions: The early diagnosis of an ectopic pregnancy is one of the greatest challenges for a physician. It requires a high index of suspicion to diagnose an ectopic pregnancy. The importance of an early diagnosis lies in the fact that the lady can be offered a conservative line of management which can definitely have a beneficial effect on her reproductive career.

    None of the in-vitro and in-vivo methods listed permits on unambiguous diagnosis when applied alone, owing to the fact that similar or even identical findings are obtained for various individual parameters in different thyroid diseases. Further, especially the in-vitro tests are also subject to extrathyroidal effects which may mask the typical findings. The limited and varying specificity and sensitivity of the tests applied, as well as the falsification of results caused by the patients' idiosyncracies and the methodology, make it necessary to interpret and evaluate the in-vivo and in-vitro findings only if the clinical situation (anamnesis and physical examination) is known. For maximum diagnostic quality of the tests, the initial probability of the assumed type of thyroid disease must be increased (formulation of the clinical problem). The concepts of exclusion diagnosis and identification must be distinguished as well as the diagnosis of functional disturbances on the one hand and of thyroid diseases on the other. Both of this requires a qualified, specific and detailed anamnesis and examination procedure, and the clinical examination remains the obligatory basis of clinical diagnostics. In case of inexplicable discrepancies between the clinical manifestations and the findings obtained with specific methods, or between the findings obtained with a specific method, the patient should be referred to an expert institution, or the expert institution should be consulted.

    Ectopic pregnancy affects 1% to 2% of all pregnancies and is responsible for 9% of pregnancy-related deaths in the United States. When a pregnant patient presents with first-trimester bleeding or abdominal pain, physicians should consider ectopic pregnancy as a possible cause. The patient history, physical examination, and imaging with transvaginal ultrasonography can usually confirm the diagnosis. When ultrasonography does not clearly identify the pregnancy location, the physician must determine whether the pregnancy is intrauterine (either viable or failing) or ectopic. Use of the beta subunit of human chorionic gonadotropin (ß-hCG) discriminatory level, the ß-hCG value above which an intrauterine pregnancy should be visualized by transvaginal ultrasonography, may be helpful. Failure to visualize an intrauterine pregnancy when ß-hCG is above the discriminatory level suggests ectopic pregnancy. In addition to single measurements of ß-hCG levels, serial levels can be monitored to detect changes. ß-hCG values in approximately 99% of viable intrauterine pregnancies increase by about 50% in 48 hours. The remaining 1% of patients have a slower rate of increase; these patients may have pregnancies that are misdiagnosed as nonviable intrauterine or ectopic. After an ectopic pregnancy has been confirmed, treatment options include medical, surgical, or expectant management. For patients who are medically unstable or experiencing life-threatening hemorrhage, a surgical approach is indicated. For others, management should be based on patient preference after discussion of the risks, benefits, and monitoring requirements of all approaches.

    Ectopic pregnancy is common among young women. Treatment can consist of either surgery with salpingectomy or salpingostomy or medical management with methotrexate. In addition to acute complications, treatment of ectopic pregnancy can result in long-term sequelae that include decreased fertility. Little is known about the patterns of care and predictors of treatment in women with ectopic pregnancy. Similarly, data on outcomes for various treatments are limited. We examined the patterns of care and outcomes for women with ectopic pregnancy. Specifically, we examined predictors of medical (vs surgical) management of ectopic pregnancy and tubal conservation (salpingostomy vs salpingectomy) among women who underwent surgery. The Perspective database was used to identify women with a diagnosis of tubal ectopic pregnancy treated from 2006-2015. Perspective is an all-payer database that collects data on patients at hospitals from throughout the United States. Women were classified as having undergone medical treatment, if they received methotrexate, and surgical treatment, if treatment consisted of salpingostomy or salpingectomy. Multivariable models were developed to examine predictors of medical treatment and of tubal conserving salpingostomy among women who were treated surgically. Among the 62,588 women, 49,090 women (78.4%) were treated surgically, and 13,498 women (21.6%) received methotrexate. Use of methotrexate increased from 14.5% in 2006 to 27.3% by 2015 (Pectopic pregnancy. There are significant race- and insurance-related disparities associated with treatment.

    Hashimoto's thyroiditis (HT) has been found to be associated with lymphoma, papillary carcinoma and Hürthle cell neoplasms of thyroid. In contrast, there are only a few reports of co-existence of HT with medullary carcinoma of thyroid. An overall prevalence of medullary carcinoma of only 0.35% has been reported in HT patients. Such a rare combination is being presented here. A 33 year old female presented with history of goiter for one year. Fine needle aspiration cytology (FNAC) of the swelling revealed cytological features suggestive of medullary carcinoma of thyroid. Histopathological examination of total thyroidectomy specimen revealed Hashimoto's thyroiditis along with medullary carcinoma of thyroid. Although Hashimoto's thyroiditis can uncommonly co-exist with thyroid neoplasm, its association with medullary carcinoma is extremely rare and hence being presented.

    Full Text Available Introduction: Ectopic pregnancy is a pregnancy with extrauterine implantation. This situation is gynecologic emergency that contributes to maternal mortality. Therefore, early recognition, based on identification of the causes of ectopic pregnancy risk factors, is needed. Methods: The design descriptive observational. The samples were pregnant women who had ectopic pregnancy at Maternity Room, Emergency Unit, Dr. Soetomo Hospital, Surabaya, from 1 July 2008 to 1 July 2010. Sampling technique was total sampling using medical records. Result: Patients with ectopic pregnancy were 99 individuals out of 2090 pregnant women who searched for treatment in Dr. Soetomo Hospital. However, only 29 patients were accompanied with traceable risk factors. Discussion:. Most ectopic pregnancies were in the age group of 26-30 years, comprising 32 patients (32.32%, then in age groups of 31–35 years as many as 25 patients (25.25%, 18 patients in age group 21–25 years (18.18%, 17 patients in age group 36–40 years (17.17%, 4 patients in age group 41 years and more (4.04%, and the least was in age group of 16–20 years with 3 patients (3.03%.

    There is strong evidence that fat accumulating in non-adipose sites, "ectopic fat", is associated with cardiovascular disease (CVD), including vascular calcification. Most previous studies of this association have assessed only a single ectopic fat depot. Therefore, our aim was to assess the association of total, regional, and ectopic fat with abdominal aorto-illiac calcification (AAC) and coronary artery calcification (CAC) in 798 African ancestry men. Participants (mean age 62) were from the Tobago Bone Health Study cohort. Adiposity was assessed via clinical examination, dual x-ray absorptiometry, and computed tomography (CT). Ectopic fat depots included: abdominal visceral adipose tissue (VAT), liver attenuation, and calf intermuscular adipose tissue (IMAT). Vascular calcification was assessed by CT and quantified as present versus absent. Associations were tested using multiple logistic regression adjusted for traditional cardiovascular risk factors. Models of ectopic fat were additionally adjusted for total body fat and standing height. All adiposity measures, except VAT, were associated with AAC. Lower liver attenuation or greater calf IMAT was associated with 1.2-1.3-fold increased odds of AAC (p ectopic fat measure was associated with CAC. Greater adiposity in the skeletal muscle and liver, but not in the visceral compartment, was associated with increased odds of AAC in African ancestry men. These results highlight the potential importance of both quantity and location of adiposity accumulation throughout the body. Copyright © 2017 Elsevier B.V. All rights reserved.

    Due to the likelihood of physical and mental health impacts following the unprecedented accident at the Fukushima Dai-ichi Nuclear Power Plant, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey to assist in the long-term health management of residents. This included thyroid ultrasound examination for all children in Fukushima. For appropriate evaluation of ultrasound screening of the thyroid, it is important to understand its reference data of thyroid findings in children in general. In order to analyze the frequencies of specific thyroid findings, we conducted ultrasound screening of the thyroid by the same procedures as used in Fukushima in 4,365 children, aged 3 to 18 years, from three Japanese prefectures. Overall, thyroid cysts were identified in 56.88% and thyroid nodules in 1.65% of the participants. Thyroid cysts and nodules with a maximum diameter of more than 5 mm were identified in 4.58% and 1.01%, respectively, and age-adjusted prevalences were 3.82% and 0.99%, respectively. Although the prevalence of cysts and nodules varied among the examination areas, no significant differences were observed among the three examination areas in the prevalence of cysts and nodules with a maximum diameter of more than 5 mm. Also, the prevalence of thyroid cysts and nodules, especially those with a maximum diameter of more than 5 mm, significantly increased with age, and showed a female predominance. We also identified ectopic thymus (1.95%), diffuse goiter (1.40%), ultimobranchial body (0.73%), lymph node swelling (0.21%) and thyroid agenesis (0.05%). This is the first ultrasound description of the age-adjusted prevalence of thyroid cysts and nodules, or of the prevalence of abnormalities other than cysts and nodules, such as ectopic thymus, in relation to age, in the general Japanese child population. We contend that this can provide relevant information for the Fukushima Health Management Survey and future population

    Ectopic pregnancy is an important cause of maternal morbidity and mortality. Women who experience fragmented care may undergo unnecessary delays to diagnosis and treatment. Based on ectopic pregnancy cases observed in clinical practice that raised our concern about fragmentation of care, we designed an exploratory study to describe the number, characteristics, and outcomes of fragmented care among patients with ectopic pregnancy at one urban academic hospital. Chart review with descriptive statistics. Fragmented care was defined as a patient being evaluated at an outside facility for possible ectopic pregnancy and transferred, referred, or discharged before receiving care at the study institution. Of 191 women seen for possible or definite ectopic pregnancy during the study period, 42 (22 %) met the study definition of fragmented care. The study was under-powered to observe statistically significant differences across groups, but we found concerning, non-significant trends: patients with fragmented care were more likely to be Medicaid recipients (65.9 vs. 58.8 %) and to experience a complication (23.8 vs. 18.1 %) compared to those with non-fragmented care. Most patients (n = 37) received no identifiable treatment prior to transfer and arrived to the study hospital with no communication to the receiving hospital from the outside provider (n = 34). Nine patients (21 %) presented with ruptured ectopic pregnancies. The fragmentation we observed in our study may contribute to previously identified socio-economic disparities in ectopic pregnancy outcomes. If future research confirms these findings, health information exchanges and regional coordination of care may be important strategies for reducing maternal mortality.

    To investigation the diagnosis and treatment of ectopic adrenocorticotrophic hormone (ACTH) syndrome. The clinical characters of 57 cases of ecotopic ACTH syndrome from Jan. 1996 to Dec. 2016 were collected and analyzed. The 57 cases included 32 males and 25 females. The age ranged from 11 to 68 years (average 32 years). ACTH levels significantly increased from 16.5 to 365.6 pmol/L, with average 77.6 pmol/L (normal range ectopic ACTH syndrome cases (44%) were group A, without identified source of ectopic hormone, were treated with bilateral or unilateral adrenalectomy due to the severity of the disease and difficulty of operation. Group B was composed of 16 cases (28%) diagnosed as ectopic ACTH syndrome by finding ectopic ACTH tumors and surgical resection. Group C included 16 cases (28%) with nonsurgical therapy. Different treatment results and prognosis were analyzed. In the study, 40 cases of the 57 had been followed up for 6 months to 10 years. In group A, of the 25 cases with bilateral or unilateral adrenalectomy, 4 died of diabetes and severe pulmonary infection, 18 survived, and 3 were lost to the follow-up, and the survival rate was 81% (18/22). In group B, of the 16 cases with radical tumor resection, 5 died of tumor recurrence 0.5-6.0 years after operation, 3 survived, and 8 were lost to the follow-up, and the survival rate was 37.5% (3/8). In group C, of the 16 non-operation patients, 4 with radiotherapy and chemotherapy died of metastases, diabetes or pulmonary infection, 6 with chemotherapy died of pulmonary infection within 1 year and the others were lost to the follow-up, and the survival rate was 0. Ectopic ACTH syndrome is difficult to treat. Adrenalectomy is effective for the management of ectopic ACTH syndrome, especially for those patients with severe Cushing's syndrome, but the primary tumor can not be located.

  8. 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.

    One of the pertinent issues associated with cellular plasticity is to understand how the delicate balance between the determined state of cells and the extent to which they can transdetermine is maintained. Employing the well-established model of generating ectopic eyes in developing wing discs of Drosophila by ectopic eyeless expression, we provide evidence for the genetic basis of this mechanism. By both loss-of-function and gain-of-function genetic analyses, we demonstrate that Matrix metalloproteinase 1 (Mmp1) plays an important role in regulating the extent of ectopic ommatidial differentiation. Transcriptional activation of ectopic Mmp1 by the morphogen Decapentaplegic (Dpp) is not triggered by its canonical signaling pathway which involves Mad. Rather, Dpp activates an alternate cascade involving dTak1 and JNK, to induce ectopic Mmp1 expression. Mutational analyses reveal that Mmp1 negatively regulates ectopic eye differentiation by restricting the rate of proliferation and the levels of expression of retinal-determining genes dachshund and eyes absent This is primarily achieved by restricting the range of Hedgehog (Hh) signaling. Importantly, the increase in proliferation and upregulation of target retinal-determining genes, as observed upon attenuating Mmp1 activity, gets significantly rescued when ectopic eyes are generated in wing discs of hh heterozygous mutants. In conjunction with the previously established instructive and permissive roles of Dpp in facilitating ectopic eye differentiation in wing discs, the outcome of this study sheds light on a mechanism by which Dpp plays a dual role in modulating the delicate balance between the determined state of cells and the extent they can transdetermine.

    In order to evaluate the clinical and sonographic findings in 60 patients with ectopic pregnancy confirmed at laparotomy, we carried out a prospective study at the Hospital de Gineco-Obstetricia del Centro Médico León, Instituto Mexicano del Seguro Social. The patients were 28.17 years old, average. The ectopic pregnancy was more common in multiparous women (80%) than in nuliparous ones. The obstetric risk factors more frequent were abortion (26.6%) and use of intrauterine device (23.3%). The clinical sign reported most common was pelvic pain, referred in 48 patients (80%). Hemodynamic changes were detected in 21.6% of the cases. The ultrasound findings were seen in most of the patients and heterogeneous adnexal mass was observed in 91.6% of them, moreover intraperitoneal fluid was reported in 61.6% of the patients with ectopic pregnancy. The heterogeneous adnexal mass had a direct relationship with the diagnosis of ectopic pregnancy and had a correlation coefficient value R = 0.99 (P < 0.01). The ultrasonographic findings seen with transvaginal technique were similar than those obtained through transabdominal procedure. We conclude that ultrasonography has a definite role in improving the diagnosis of ectopic pregnancy.

    Macroscopic ectopic or heterotopic ganglionic tissue within the cauda equina is a very rare pathological finding and is usually associated with spinal dysraphism. However, it may mimic genuine neoplasms of the cauda equina. The authors describe a 29-year-old woman with a history of back pain, right leg pain, and urinary incontinence in whom imaging demonstrated an enhancing mass located in the cauda equina at the L1-2 interspace. The patient subsequently underwent biopsy and was found to have a focus of ectopic ganglionic tissue that was 1.3 cm in greatest dimension. To the authors' knowledge, ectopic or heterotopic ganglionic tissue within the cauda equina in a patient without evidence of spinal dysraphism has never been reported. This patient presented with imaging and clinical findings suggestive of a neoplasm, and an open biopsy proved the lesion to be ectopic ganglionic tissue. The authors suggest that ectopic ganglionic tissue be added to the list of differential diagnoses of a space-occupying lesion arising from the cauda equina.

    Thyroiditis encompasses a group of disorders characterized by thyroid inflammation. Though clinically indistinguishable from silent thyroiditis, postpartum thyroiditis occurs in women within 12 months after delivery. Recurrent postpartum thyroiditis in subsequent pregnancies is common, but recurrent silent thyroiditis is rare. We reported a case of patient with recurrent episodes of thyroiditis, unrelated to pregnancy, after an episode of postpartum thyroiditis. It is of interest that postpar...

    Full Text Available Abstract Background Mounting evidence has indicated that ABI3 (ABI family member 3 function as a tumor suppressor gene, although the molecular mechanism by which ABI3 acts remains largely unknown. Methods The present study investigated ABI3 expression in a large panel of benign and malignant thyroid tumors and explored a correlation between the expression of ABI3 and its potential partner ABI3-binding protein (ABI3BP. We next explored the biological effects of ABI3 ectopic expression in thyroid and colon carcinoma cell lines, in which its expression was reduced or absent. Results We not only observed that ABI3 expression is reduced or lost in most carcinomas but also that there is a positive correlation between ABI3 and ABI3BP expression. Ectopic expression of ABI3 was sufficient to lead to a lower transforming activity, reduced tumor in vitro growth properties, suppressed in vitro anchorage-independent growth and in vivo tumor formation while, cellular senescence increased. These responses were accompanied by the up-regulation of the cell cycle inhibitor p21 WAF1 and reduced ERK phosphorylation and E2F1 expression. Conclusions Our result links ABI3 to the pathogenesis and progression of some cancers and suggests that ABI3 or its pathway might have interest as therapeutic target. These results also suggest that the pathways through which ABI3 works should be further characterized.

    Kidney in ectopic position is dysplasic, and associated to other malformations. The advent of a lithiasis in these conditions rises questions about therapeutic options. We report on five observations of pelvic ectopic kidney with urinary lithiasis. Patients were aged from 16 to 42 years. Kidney was non functional in two cases, or with normal appearance sized 10 to 12 cm. We performed total nephrectomy in two cases, pyelolithotomy in the other cases. Surgical approach was subperitoneal via iliac route. A dismembered pyeloplasty was associated in one case. All patients did well. Radiologic control at 6 and 12 months showed no recurrence in a well functioning kidney. Surgical lithotomy is advocated as a treatment in urinary lithiasis affecting ectopic kidney. It is an easy procedure which permits correction of other associated malformations.

  19. Several early interventions for ectopic maxillary canines.

    Full Text Available Maxillary canine impactation is often encountered in orthodontic clinical practice and the aetiology is associated to genetic factors as well as local space factors. If preventive treatment is not started in ectopic maxillary canines, some possible consequences may occur, such as resorption of the roots of the neighboring permanent teeth, cysts, ankylosis and expensive surgical and orthodontic treatment. The aim of this review was to preset several early treatment modalities for ectopic maxillary canines based on recent scientific evidence. Four are the most important: Only extractions intervention, extraction of deciduous canines with cervical pull headgear, active intervention in late mixed dentition and active intervention in early mixed dentition. These different modalities showed a greater increasing the rate of normal eruption of ectopic canines ( 80-97%. The extraction of primary canine alone is still an effective method to prevent canine impactation, whose success rate would be increased if some other method interceptive is added.

    2017-06-01

    Primary intraorbital ectopic meningiomas are rare and their existence remains controversial. We present a 30-year-old female with painless, non-axial proptosis and a palpable superomedial mass. The MRI demonstrated that the mass had no optic nerve sheath or sphenoid wing involvement and was initially reported to have no intracranial extension. The patient was initially thought to have an ectopic orbital meningioma. Subsequent multidisciplinary team (MDT) consultation and further specialist review of the MRI revealed a subtle dural tail connecting to an enhancing mass in the olfactory groove. Biopsy revealed a WHO Grade 1 transitional meningioma with an infiltrative pattern. We argue that some previously reported cases of ectopic meningioma may lack the requisite imaging to discover the primary disease. Our report highlights the importance of MRI in this group of patients and the role of a skull-base MDT with specialist neuroradiology input to determine the true origin and extent of these extradural orbital meningiomas.

    2012-12-01

    To describe extreme hyperprolactinemia originating from a pituitary adenoma in the wall of an ovarian dermoid. This is a description of an unusual case and a review of ectopic prolactin production. Ectopic production of prolactin is a rare condition that has been reported in isolated organ system pathology including ovaries. An ovarian dermoid is a benign neoplasm that has the potential for active unregulated endocrine function. Hyperprolactinemia can result from functioning lactotrophs found in ovarian dermoids and can lead to clinical sequelae. Definitive treatment of the condition requires surgical removal of the functioning endocrine tissue. Extreme hyperprolactinemia caused by a pituitary tumor located within a dermoid has not been reported before. We present a case of profound hyperprolactinemia originating from a pituitary adenoma found in the wall of an ovarian dermoid and give a broad overview of the condition and literature. Ectopic prolactin production should always be considered in symptomatic patients found to have elevated serum levels and no findings on brain imaging.

  2. Ectopic pregnancy after levonorgestrel emergency contraception

    2013-08-01

    Full Text Available Levonorgestrel Emergency Contraception (LNG-EC is the safest and the most commonly used oral regimen that can be used after an unprotected intercourse. Although it is highly effective, failures can occur especially if it is used in the peri /or postovulatory period. It can not inhibit ovulation if used in these periods and the altered tubal motility together with the ciliary dysfunction can prevent the transfer of the fertilized ovum from the fallopian tube to the endometrial cavity, causing an ectopic pregnancy, which is one of the important concerns after failed LNG-EC. This risk was reported not to be higher than the risk of ectopic pregnancy observed in the general population, but the users of this medication should still warned about this risk. Here we report a case of ectopic pregnancy from Turkey after midcyclic use and failure of LNG-EC. [Int J Reprod Contracept Obstet Gynecol 2013; 2(4.000: 749-750

    Li, H; Li, J

    2015-04-01

    Thyroid disorders include autoimmune thyroid diseases (AITD), thyroid goiter, nodule and cancer. AITD mainly consist of autoimmune thyroiditis and Graves disease. The common characteristic of thyroid disorders is female preponderance in their prevalence. The female-to-male rate ratio is reported at 4~6:1 for AITD and about 3~4:1 for thyroid nodule. For PTC, it is greatest during reproductive age and drops from five and more in patients aged 20-24, to 3.4 in patients aged 35-44 to one in patients over 80. The effects of female gonadal hormones and X chromosome inactivation on thyroid gland and immune system greatly contribute to the female predilection of AITD. The former mainly include prolactin and estrogen. The direct actions of estrogen on the thyroid tissue contribute to the development of thyroid goiter, nodule and cancer in women.

    Ectopic adrenocorticotropic hormone (ACTH) secretion is a less common cause of Cushing syndrome and is seen in 5 to 10% of cases with endogenous hypercortisolemia. We hereby describe our experience of patients with ectopic ACTH syndrome, who have been managed over the past 10 years at a tertiary care center in Southern India. The inpatient and outpatient records of patients from 2006 to 2015 were retrospectively reviewed. The clinical features, clinical history, biochemical values, imaging features, including radiologic findings and positron emission tomography scans, management, details of follow-up, and outcomes, were documented. We compared the biochemical findings in these patients with 20 consecutive patients with Cushing disease (Cushing syndrome of pituitary origin). A total of 21 patients were studied. The median age at presentation was 34 years (range, 19 to 55 years). Seven patients had thymic carcinoid, 7 had bronchial carcinoid, 3 had lung malignancies, 2 had medullary carcinoma thyroid, 1 patient had a pancreatic neuroendocrine tumor, and 1 patient had an occult source of ACTH. The most common clinical features at presentation were muscle weakness (95%), hyperpigmentation (90%), facial puffiness (76%), easy bruising (61%), edema (57%), and striae (52%). Extensive acne was seen in a large number of patients (43%). Only 3 patients (14%) had central obesity. The median 8 am cortisol was 55.5 μg/dL (range, 3.8 to 131 μg/dL), median 8 am ACTH was 207 pg/mL (range, 31.1 to 703 pg/mL), and the median 24-hour urinary free cortisol was 2,484 μg (range, 248 to 25,438 μg). Basal cortisol and ACTH, as well as midnight cortisol and ACTH level, were markedly higher in patients with ectopic Cushing syndrome as compared to patients with Cushing disease. Twelve of 21 patients had developed life-threatening infections by follow-up. Nine patients had undergone surgical intervention to address the primary tumor. However, only 1 patient exhibited a complete cure on

    Ectopic eruption of the first permanent molar is a relatively common occurence in the developing dentition. A range of treatment options are available to the clinician provided that diagnosis is made early. Non-treatment can result in premature exfoliation of the second primary molar, space loss and impaction of the second premolar. This paper will describe the management of ectopic first permanent molars, using clinical examples to illustrate the available treatment options. CLINICAL RELEVANCE: This paper is relevant to every general dental practitioner who treats patients in mixed dentition.

    2011-01-01

    Full Text Available Hydatidiform moles are abnormal gestations characterized by the presence of hydropic changesaffecting some or all of the placental villi. Hydatidiform moles arise as a result of the fertilizationof an abnormal ovum. In this report, the patient was a 29 year old Asian woman who had inductionof ovulation with letrozol. Since the majority of molar gestations arise within the uterine cavitythus the occurrence of a hydatidiform mole within ectopic gestational tissue is rare. It is importantto differentiate a hydatidiform mole from a conventional ectopic pregnancy, particularly in infertilewomen who have a history of ovulation induction.

    The development of intranasal ectopic teeth is rare. Although they are more commonly seen in the palate and maxillary sinus, they can also be found in the mandibular condyle, coronoid process, and nasal cavity. A 30-year-old male patient presented with a complaint of headache. Computed tomography of the paranasal sinuses showed a bony mass in the right maxillary sinus wall, 1 cm in size. He did not have any history of maxillofacial trauma or operation. The mass was removed via a Caldwell-Luc procedure. It looked like a tooth. Histopathologic diagnosis was made as ectopic molar tooth. The patient was asymptomatic two weeks after the operation.

    Primary mediastinal large B-cell lymphoma is a subtype of diffuse large B-cell lymphoma, arising in the mediastinum from putative thymic B-cell origin with distinctive clinical and genetic features. Generally, primary mediastinal large B-cell lymphoma is believed as only deriving in the mediastinum. The current study presents a rare case of primary mediastinal large B-cell lymphoma which arising from thyroid in a renal recipient with Hashimoto's thyroiditis. Moreover, we devoted a discussion to the relationship among primary mediastinal large B-cell lymphoma, immunomodulatory therapy and autoimmune diseases. The immunologic derangement induced by long-term immunomodulatory therapy and Hashimoto's thyroiditis may be the possible cause for the ectopic lymphoma.

    2013-10-01

    Full Text Available Background: Subclinical thyroid disorders usually do not produce symptoms of thyroid disease until they turn into over thyroid disease. Thyroid disease is more common in people with diabetes mellitus than in the general population and it is important to detect thyroid disorder before its clinical manifestation. Subclinical hypothyroidism (SCH can produce dyslipidemia, obesity thus resulting increased predisposition to coronary artery disease. Subclinical hyperthyroidism can aggravate hyperglycemia and impair blood sugar control. Objectives: Our objective is to determine the prevalence of subclinical thyroid disorders in patients with type 2 diabetes mellitus (T2DM and to analyze the clinical and metabolic profile of patients with this dual endocrine disorder. Methods and Results: One hundred consecutive type 2 diabetic patients without clinical manifestations of thyroid disorders were screened for SCH and subclinical hyperthyroidism using serum free T 3 , free T 4 and thyroid stimulating hormone (TSH levels. Individuals of subclinical thyroid disease were further screened for thyroperoxidase (TPO antibodies. SCH was detected in 13% of type 2 diabetic patients and none had subclinical hyperthyroidism in our study. SCH was common among females with type 2 diabetes (84.6%. Elevated TPO antibody levels were present in 84.6% SCH patients. Diabetic retinopathy among SCH patients showed significant association with higher serum TSH levels. Left ventricular diastolic dysfunction was present in 30.8% of SCH patients. Conclusion: SCH is common among type 2 diabetic patients, especially in females. It is most commonly secondary to autoimmune thyroid disease. Microvascular complications are commonly observed in this group of patients with dual endocrinal disorder and treating physician should be aware of the impact and should routinely screen SCH to prevent complications.

    Cho, Moon Kyoung

    2015-12-01

    The thyroid hormones act on nearly every cell in the body. Moreover, the thyroid gland continuously interacts with the ovaries, and the thyroid hormones are involved in almost all phases of reproduction. Thyroid dysfunctions are relatively common among women of reproductive age, and can affect fertility in various ways, resulting in anovulatory cycles, high prolactin levels, and sex hormone imbalances. Undiagnosed and untreated thyroid disease can be a cause of subfertility. Subclinical hypothyroidism (SCH), also known as mild thyroid failure, is diagnosed when peripheral thyroid hormone levels are within the normal reference laboratory range, but serum thyroid-stimulating hormone levels are mildly elevated. Thyroid autoimmunity (TAI) is characterized by the presence of anti-thyroid antibodies, which include anti-thyroperoxidase and anti-thyroglobulin antibodies. SCH and TAI may remain latent, asymptomatic, or even undiagnosed for an extended period. It has also been demonstrated that controlled ovarian hyperstimulation has a significant impact on thyroid function, particularly in women with TAI. In the current review, we describe the interactions between thyroid dysfunctions and subfertility, as well as the proper work-up and management of thyroid dysfunctions in subfertile women.

    Optimizing effective prevention and treatment of type 2 diabetes in youth is limited by incomplete understanding of its pathophysiology and how this varies across ethnicities with high risk. The aim of this study was to examine the contribution of visceral adipose tissue (VAT), hepatic fat fraction (HFF), and pancreatic fat fraction (PFF) to prediabetes in overweight/obese African American (AA) and Latino youth. We conducted a cross-sectional study in an academic pediatric care facility. A total of 148 healthy, overweight/obese adolescents (56 AA, 92 Latino; 72 males, 76 females; age, 15.5 ± 1.2 y; BMI z-score, 2.1 ± 0.5) participated in the study. They were normal glucose tolerant (n = 106) and prediabetic (n = 42), based on fasting glucose of 100-125 mg/dL and/or 2-hour glucose of 140-199 mg/dL, and/or hemoglobin A1C 6.0-6.4%. We measured sc abdominal adipose tissue, VAT, HFF, and PFF by 3-Tesla magnetic resonance imaging and measured total body fat by dual-energy x-ray absorptiometry. Adolescents with prediabetes had 30% higher HFF (P = .001) and 31% higher PFF (P = .042), compared to those with normal glucose tolerance after controlling for age, sex, pubertal stage, ethnicity, total percentage body fat, and VAT. Logistic regression showed that PFF predicted prediabetes in AAs and HFF predicted prediabetes in Latinos, with the odds of having prediabetes increased by 66% for every 1% increase in PFF in African Americans, and increased by 22% for every 1% increase in HFF in Latinos. These data demonstrate that ectopic fat phenotypes associated with prediabetes are established by adolescence. Ethnic differences in the deposition of ectopic fat in adolescents with prediabetes may differ, with pancreatic fat in AAs, vs hepatic fat in Latino adolescents, being associated with diabetes risk.

    Full Text Available 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.

    Ades, Alex; Parghi, Sneha

    To demonstrate a technique for the laparoscopic surgical management of cesarean section scar ectopic pregnancy. Step-by-step presentation of the procedure using video (Canadian Task Force classification III). Cesarean section scar ectopic pregnancy is a rare form of ectopic pregnancy with an incidence ranging from 1:1800 to 1:2216. Over the last decade, the incidence seems to be on the rise with increasing rates of cesarean deliveries and early use of Doppler ultrasound. These pregnancies can lead to life-threatening hemorrhage, uterine rupture, and hysterectomy if not managed promptly. Local or systemic methotrexate therapy has been used successfully but can result in prolonged hospitalization, requires long-term follow-up, and in some cases treatment can fail. In the hands of a trained operator, laparoscopic resection can be performed to manage this type of pregnancy. Consent was obtained from the patient, and exemption was granted from the local Internal Review Board (The Womens' Hospital, Parkville). In this video we describe our technique for laparoscopic management of a cesarean scar ectopic pregnancy. We present the case of a 34-year-old G4P2T1 with the finding of a live 8-week pregnancy embedded in the cesarean section scar. The patient had undergone 2 previous uncomplicated cesarean sections at term. On presentation her β-human chorionic gonadotropin (β-hCG) level was 52 405 IU/L. She was initially managed with an intragestational sac injection of potassium chloride and methotrexate, followed by 4 doses of intramuscular methotrexate. Despite these conservative measures, the level of β-hCG did not adequately fall and an ultrasound showed a persistent 4-cm mass. A decision was made to proceed with surgical treatment in the form of a laparoscopic resection of the ectopic pregnancy. The surgery was uneventful, and the patient was discharged home within 24 hours of her procedure. Her serial β-hCG levels were followed until complete resolution

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.

    The aims of our study were to determine whether shear wave elastography (SWE) can improve the conventional B-mode differentiation of thyroid lesions, determine the most accurate SWE parameter for differentiation and assess the influence of microcalcifications and chronic autoimmune thyroiditis on SWE values. We examined 119 patients with 169 thyroid nodules who prospectively underwent B-mode ultrasound and SWE using the same ultrasound machine. The parameters assessed using SWE were: mean elasticity within the entire lesion (SWE-whole) and mean (SWE-mean) and maximum (SWE-max) elasticity for a 2-mm-diameter region of interest in the stiffest portion of the lesion, excluding microcalcifications. The discriminant powers of a generalized estimating equation model including B-mode parameters only and a generalized estimation equation model including both B-mode and SWE parameters were assessed and compared using the area under the receiver operating characteristic curve, in association with pathologic verification. In total, 50 and 119 malignant and benign lesions were detected. In generalized estimated equation regression, the B-mode parameters associated with higher odds ratios (ORs) for malignant lesions were microcalcifications (OR = 4.3), hypo-echogenicity (OR = 3.13) and irregular margins (OR = 10.82). SWE-max was the only SWE independent parameter in differentiating between malignant and benign tumors (OR = 2.95). The area under the curve for the B-mode model was 0.85, whereas that for the model combining B-mode and SWE parameters was 0.87. There was no significant difference in mean SWE values between patients with and without chronic autoimmune thyroiditis. The results of the present study suggest that SWE is a valuable tool for the characterization of thyroid nodules, with SWE-max being a significant parameter in differentiating benign and malignant lesions, independent of conventional B-mode parameters. The combination of SWE parameters and

    In this study three problems concerning interactions between thyroid and cardiovascular system are discussed. Cardiac arrhythmias, congestive heart failure, pleural effusion, hyperlipidaemia, arterial hypertension may be consequences of thyroid disorders leading to inappropriate hormone secretion. During such illnesses as heart failure, myocardial infarction and in patients undergoing coronary artery bypass surgery profound changes may occur in thyroid hormone metabolism known as sick euthyroid syndrome. Treatment with amiodarone may lead to changes in thyroid tests results and to development of hypothyroidism or thyrotoxicosis.

    Ectopic pregnancy is associated with maternal morbidity and mortality during early pregnancy. Ectopic pregnancy occurs in approximately 2% of all pregnancies, and the risk of ectopic pregnancy is increased by eight-fold in women with a history of eopic pregnancy. However, recurrent ectopic pregnancy after ipsilateral partial salpingectomy is quite rare. The authors experienced a case of recurrent ectopic pregnancy in the distal remnant after right partial salpingectomy. In this case report, they discuss this unusual case and provide a brief review of the literature.

    To describe the radiological findings associated with ectopic ureterocele and ectopic ureter in pediatric patients. To assess the role of ultrasound (US), serial micturating cystourethrography (SM-CU) and intravenous urography (IVU) in the diagnosis of these two entities. The authors performed a retrospective study of 132 patients, 73 with ectopic ureterocele and 59 with ectopic ureter. The imaging studies used were US, SMCU, IVU and methods to determine renal function (diuretic renography and renal scintigraphy). The findings were confirmed during surgery in every case. The most common radiological findings in ectopic ureterocele were renal duplication (86,3%). vesicoureteral reflux (VUR) to the lower half of the kidney (46.6%), dilatation of the lower pole of the kidney (38.4%) and contralateral duplication (30.1%). In boys, the ectopic ureter entered via bladder neck and posterior urethra (73.7%) or into seminal vesicles (15.8%); in girls, it went to vagina (32.5%), bladder neck (30%) or urethra (22.5%). Renal duplication was associated in 64.4%, with VUR to the ectopic ureter in 21% while there was a single renal system in 35.6%, with VUR to the ectopic ureter in 57.1% and contralateral renal agenesis in 19%. Eighteen patients (13.6%) presented a single, dy plastic, nonfunctioning renal system (6 cases of ureterocele and 12 of ectopic ureter). Knowledge of the embryological development of ureteral duplication is essential for the understanding of these two entities and helps to differentiate between them, thus facilitating a sometimes complicated diagnosis. Ectopic ureters and ureteroceles accompanied by a single, dysplastic renal system are associated with a greater incidence of congenital anomalies and a higher rate of complications than the duplicate systems. A prenatal US examination enables early diagnosis. The anatomical information provided by US is, on occasion, more valuable than that resulting from IVU or SMCU, However, IVU is indispensable in girls

    The impact of an ectopic pregnancy in the next generation is unknown. Our aim was to compare reproductive outcomes in daughters of women with and without ectopic pregnancy. Designed as a historical prospective controlled cohort study with data collected in four Danish registries from 1977-2009, women with ectopic pregnancy during 1977-1982 were age-matched to women without ectopic pregnancy. Daughters of these two cohorts were followed until 2009. We compared 5126 daughters of women with ectopic pregnancy with 19 928 daughters of women without ectopic pregnancy. The daughters of women with ectopic pregnancy had a 1.5-fold (95% confidence interval 1.2-1.9) increased risk of ectopic pregnancy, while for deliveries this was 1.0 (1.0-1.1), for miscarriages 1.1 (1.0-1.2), and for induced abortions 1.3 (1.2-1.4). Daughters of mothers with ectopic pregnancy have a 50% higher risk of ectopic pregnancy than daughters of women without an ectopic pregnancy, but a normal delivery rate.

    2016-10-18

    Ectopic parathyroid adenomas can occur in numerous anatomic locations. While ectopic parathyroid adenomas can rarely occur in the pharyngeal region, this has not previously been described in the soft palate. We report the first case of ectopic parathyroid adenoma within the soft palate. A 59 year old woman presented with hyperparathyroidism. She remained persistently hyperparathyroid after initial parathyroidectomy. Repeat exploration for a lesion suspicious on PET-CT for an ectopic parathyroid adenoma in the parapharyngeal region was unsuccessful in treating the hyperparathyroidism. An ectopic adenoma in the soft palate was eventually discovered. Removal through a transoral approach was successful in treating the hyperparathyroidism. Ectopic parathyroid adenomas can occur in various anatomical locations that may be missed even with the use of the various imaging modalities. The soft palate should be added to the list of possible ectopic locations high in the neck.

    Full Text Available The cardiovascular signs and symptoms of thyroid disease are some of the most clinically relevant findings that accompany both hyperthyroidism and hypothyroidism. On the basis of the understanding of the mechanisms of thyroid hormone action on the heart and cardiovascular system, it is possible to explain the changes in cardiac output, cardiac contractility, blood pressure and rhythm disturbances that result from thyroid dysfunction. In the present review will integrate what is known about the mechanisms of thyroid hormone action on the heart and the alterations in thyroid hormone metabolism that accompany chronic congestive heart failure.

    Tomer, Yaron; Menconi, Francesca

    2009-12-01

    Interferon-alpha (IFNalpha) is used for the treatment of various disorders, most notable chronic hepatitis C virus (HCV) infection. One of the commonest side effects of IFNalpha therapy is thyroiditis, with up to 40% of HCV patients on IFNalpha developing clinical or subclinical disease. In some cases interferon induced thyroiditis (IIT) may result in severe symptomatology necessitating discontinuation of therapy. IIT can manifest as clinical autoimmune thyroiditis, presenting with symptoms of classical Hashimoto's thyroiditis or Graves' disease, or as non-autoimmune thyroiditis. Non-autoimmune thyroiditis can manifest as destructive thyroiditis, with early thyrotoxicosis and later hypothyroidism, or as non-autoimmune hypothyroidism. While the epidemiology and clinical presentation of IIT have been well characterized the mechanisms causing IIT are still poorly understood. It is likely that the hepatitis C virus (HCV) itself plays a role in the disease, as the association between HCV infection and thyroiditis is well established. It is believed that IFNalpha induces thyroiditis by both immune stimulatory effects and by direct effects on the thyroid. Early detection and therapy of this condition are important in order to avoid complications of thyroid disease such as cardiac arrhythmias.

    Thyroid hormones modulate every component of the cardiovascular system necessary for normal cardiovascular development and function. When cardiovascular disease is present, thyroid function tests are characteristically indicated to determine if overt thyroid disorders or even subclinical dysfunction exists. As hypothyroidism, hypertension, and cardiovascular disease all increase with advancing age, monitoring of thyroid-stimulating hormone, the most sensitive test for hypothyroidism, is important in this expanding segment of our population. A better understanding of the impact of thyroid hormonal status on cardiovascular physiology will enable health care providers to make decisions about thyroid hormone evaluation and therapy in concert with evaluating and treating hypertension and cardiovascular disease. The goal of this review is to access contemporary understanding of the effects of thyroid hormones on normal cardiovascular function and the potential role of overt and subclinical hypothyroidism and hyperthyroidism in a variety of cardiovascular diseases.

    Science.gov (United States)

    Ghervan, Cristina

    2011-03-01

    Thyroid ultrasound is easy to perform due to the superficial location of the thyroid gland, but appropriate equipment is mandatory with a linear high frequency transducer (7.5 - 12) MHz. Some pathological aspects of the thyroid gland are easily diagnosed by ultrasound, like the enlargement of the thyroid volume (goiter) or the presence of nodules and cysts; while other aspects are more difficult and need more experience (diffuse changes in the structure, echogenicity and vascularization of the parenchyma, differential diagnosis of malignant nodules). Ultrasound has become the diagnostic procedure of choice in guidelines for the management of thyroid nodules; most structural abnormalities of the thyroid need evaluation and monitoring but not intervention. A good knowledge of the normal appearance of the thyroid gland is compulsory for an accurate ultrasound diagnosis.

    2006-12-15

    We describe the 2D reformatted and 3D volume rendered images by MDCT in a patient with an episode of acute bleeding from the colonic stoma. This case indicates that the 2D reformatted and 3D volume rendered images are useful to detect this rare complication of portal hypertension, and they help to tailor adequate treatment for the patients with bleeding from stomal varices. Ectopic varices are an uncommon cause of gastrointestinal hemorrhage, but they account for up to 5% of all variceal bleedings (1). Bleeding from stomal varices has been reported in up to 20% of the patients suffering with chronic liver failure with permanent stoma (2). However, the diagnosis of stomal varices is difficult because bleeding from stoma may also be associated with lower gastrointestinal bleeding. To the best of our knowledge, the 2D reformatted and 3D volume rendered images by MDCT for visualization of ectopic stomal varices have not been previously reported in the medical literature.

    2012-01-01

    Full Text Available Background: Dyshormonogenetic goiter (DG refers to familial goitres owing to an inherited defect in the metabolism of thyroid hormones and accounts for 10-15% of all cases of congenital hypothyroidism. Aim and Objective: To identify dysmorphic features, cardiac and urogenital anomalies in patients with DG following in the pediatric endocrinology clinic. Materials and Methods: Eight adolescents following the pediatric endocrinology clinic for hypothyroidism and associated stigmata were identified with dyshormonogenesis using 99mTc radionuclide thyroid scintigraphy and confirmation by the Perchlorate discharge test during a 6-month period from January to July 2012. Screening for associated malformations was done using clinical examination, echocardiography and ultrasonography of abdomen. Results: The eight patients (two boys and six girls had a mean age of 9.87 years. The mean duration of goitre was 36.12 months. Two patients had mental retardation and delayed developmental milestones one of whom had ectopic left kidney on renal scintigraphy. Mitral regurgitation was seen in one patient whereas renal anomalies in the form of ectopic kidney and small/contracted kidney with grade III hydronephrosis was seen in two patients. Penoscrotal hypospadias was identified in one of the patients who also had small/contracted kidney with grade III hydronephrosis and underwent pyeloplasty for the same. Dysmorphic features in the form of high arched palate, depressed nasal bridge and low set ears was seen in one patient. Conclusion: DG is associated with other extra-thyroidal congenital anomaly, some of which may need to be treated.

    Riedel thyroiditis is a benign disease, which is often self-limited. Examinations, such as CT and histologic diagnosis can distinguish it from malignant neoplasms and hashimoto's thyroiditis. Riedel thyroiditis is an uncommon form of chronic thyroiditis in which the thyroid gland is replaced by fibrous tissue. It can be cured by surgery and medicine.

    Perforation of jejunal diverticulum is a rare complication. Here, we report a case of jejunal diverticulum penetration with surrounding ectopic pancreas. An 83-year-old female patient was admitted to our department with acute onset of severe abdominal pain lasting for half a day. Abdominal computed tomography showed outpouching of the small intestine that contained air/fluid, with multiple surrounding air bubbles in the mesentery of the small intestine. She was diagnosed with penetration of the small intestine, and an emergency laparotomy was indicated. The penetrated jejunal diverticulum was identified ~20-cm distal to the ligament of Treitz. Partial resection of the jejunum was performed, and her postoperative course was uneventful. The pathological findings confirmed diverticulum penetration into the mesentery and severe inflammation at the site, with surrounding ectopic pancreas. Furthermore, the pancreatic ducts were opened through the penetrated diverticulum. This rare case shows that the ectopic pancreas might have caused penetration of jejunal diverticulum owing to the pancreatic duct opening through the diverticulum.

    The cardiovascular system is a known target for thyroid hormone. Early-life cardiovascular alterations may lead to a higher risk of cardiovascular disease in adulthood. Little is known about the effects of thyroid hormone on cardiovascular function during childhood, including the role of body composition in this association. Population-based prospective cohort of children (n = 4251, median age 6 years, 95% range: 5.7-8.0 years). Thyroid-stimulating hormone (TSH) and free thyroxine (FT4) concentrations were measured to assess thyroid function. Left ventricular (LV) mass was assessed with echocardiography. Arterial stiffness was assessed with carotid-femoral pulse wave velocity (CFPWV). Systolic and diastolic blood pressure (BP) was measured. Body composition was assessed by dual-energy X-ray absorptiometry scan. FT4 was inversely associated with LV mass (P = 0.002), and with lean body mass (P cardiovascular function during early childhood. © 2017 European Society of Endocrinology.

    At the molecular level, the uptake of radioiodine and pertechnetate is proportional to the expression of the thyroidal sodium/iodine symporter (NIS). Qualitative and quantitative scintigraphic evaluation of the thyroid is performed with a gamma camera fitted with an on-line computer system and enables determination of the iodine uptake or the technetium uptake (TCTU) as an iodine clearance equivalent. Despite new molecular genetic insights into congenital hypothyroidism, the iodine-123 or pertechnetate scan remains the most accurate test for the detection of ectopic thyroid tissue. Following the identification of specific mutations of the genes coding for the NIS, thyroid peroxidase and pendrin, the discharge test has lost its role in establishing the diagnosis of inherited dyshormonogenesis, but it is still of value in the assessment of defect severity. In PDS mutations the test can be used to establish the diagnosis of syndromic disease. Quantitative pertechnetate scintigraphy is the most sensitive and specific technique for the diagnosis and quantification of thyroid autonomy. The method has proved to be valuable in risk stratification of spontaneous or iodine-induced hyperthyroidism, in the estimation of the target volume prior to radioiodine therapy and in the evaluation of therapeutic success after definitive treatment. In iodine deficiency areas the thyroid scan remains indispensable for the functional characterisation of a thyroid nodule and is still a first-line diagnostic procedure in cases of suspected thyroid malignancy. This is especially of importance in patients with Graves' disease, among whom a relatively high prevalence of cancer has been found in cold thyroid nodules. While determination of the TCTU is without any value in the differentiation between autoimmune thyroiditis and Graves' disease in most cases, it is of substantial importance in the differentiation between hyperthyroid autoimmune thyroiditis and Graves' disease.

    Ectopic ureters are often very difficult to diagnose with conventional diagnostic modalities (physical examination, ultrasound, intravenous urography, cystography, urethro-cystoscopy, isotop examinations) in children. The authors report their experience with a relatively new method, the magnetic resonance urography (MRU) diagnosing ectopic ureters in childhood. MRU was used in 7 girls to detect an ectopic ureter in the last 3 years. On the basis of typical clinical signs, an ectopic ureter was suspected in all patients, but it could not be demonstrated by conventional diagnostic methods. Thus, MRU was done to confirm the suspected diagnosis. In all of the 7 patients, the examinations demonstrated ectopic ureters with the intraoperative findings further confirming the pre-operative diagnosis. In 2 patients, the intraoperative findings of the upper urinary tract anomalies were slightly different from the MRU report. The MRU is a reliable diagnostic method to diagnose ectopic ureters which are not easily detectable with conventional diagnostic modalities.

    Abdominal ectopic pregnancy is an extremely rare entity, which represents 1% of all ectopic pregnancies and is associated with high maternal and fetal morbidity and mortality. The maternal mortality risk of an abdominal ectopic pregnancy is seven to eight times greater than the risk of a tubal ectopic pregnancy and is 90 times greater than the risk of intrauterine pregnancy. This is a disease of difficult diagnosis that often takes place late. We report the case of a patient with an abdominal ectopic pregnancy, which was diagnosed by abdominal ultrasound in the second trimester; the patient was suc- cessfully treated with exploratory laparotomy with complete removal of the fetus and placenta. We provide a review of the literature on the risk factors for abdominal ectopic pregnancy, diagnostic tests and therapeutic options.

    Full Text Available Bleeding from ectopic varices, which is rare in patients with portal hypertension, is generally massive and life-threatening. Forty-three patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The frequency of ectopic varices was 43/1218 (3.5% among portal hypertensive patients in our ward. The locations of the ectopic varices were rectal in thirty-two, duodenal in three, intestinal in two, vesical in three, stomal in one, and colonic in two patients. Endoscopic or interventional radiologic treatment was performed successfully for ectopic varices. Hemorrhage from ectopic varices should be kept in mind in patients with portal hypertension presenting with lower gastrointestinal bleeding.

    Full Text Available Introduction. Primary thyroid lymphomas constitute up to 5% of all thyroid malignancies and can be divided into non-Hodgkin’s lymphomas (NHLs of B- and T-cell types, as well as Hodgkin’s lymphomas. Mucosa-associated lymphoid tissue (MALT lymphomas are a relatively recently recognized subset of B-cell NHLs, and they are listed as extranodal marginal zone lymphomas according to the revised European-American lymphoma classification. Case Report. We report an uncommon case of a 44-year-old man, who noted a painless, growing mass on right side of his neck of the three-month duration. Thyroid profile was within normal limits. FNAC showed lymphocytic thyroiditis. The patient underwent a right hemithyroidectomy. The histologic examination and the immunohistochemistry showed an extra nodal marginal B-cell type maltoma (malt lymphoma. CHOP chemotherapy with rituximab was given. The clinical course has been favourable in the first year of followup, with no evidence of local or systemic recurrence of the disease. Discussion. Marginal zone lymphoma encompasses a heterogeneous group of B-cell tumours that variously arise within the lymph nodes, spleen, or extranodal tissues. A case of maltoma of thyroid is presented for its rarity and diagnostic dilemmas. Conclusion. Maltomas are slow-growing lymphomas. The optimal treatment and followup of patients with thyroid maltomas remain controversial at present.

    Medullary thyroid carcinoma (MTC), which originates from thyroid parafollicular C cells, accounts for 3 to 5% of thyroid malignancies. MTC occurs either sporadically or in an inherited autosomal dominant manner. Hereditary MTC occurs as a familial MTC or as a part of multiple endocrine neoplasia (MEN) type 2A and B syndromes. A strong genotype-phenotype correlation has been observed between hereditary MTC and germ-line ?gain of function? mutations of the RET proto-oncogene. Most cases of pedi...

    Ectopic molar pregnancy is a rare occurrence and consequently not often considered as a diagnostic possibility. We report two cases of molar hydatidiform tubal pregnancy. Diagnosis of ectopic pregnancy was confirmed on clinical biological and sonographic investigations. Diagnosis of molar pregnancy was done on histopathology. The clinical course was favorable for both patients. Although rare, molar changes can occur at any site of an ectopic pregnancy. Clinical diagnosis of a molar pregnancy is difficult but histopathology is the gold standard for diagnosis.

    Full Text Available Abstract Background Olfactory receptors (ORs are the largest gene family in the human genome. Although they are expected to be expressed specifically in olfactory tissues, some ectopic expression has been reported, with special emphasis on sperm and testis. The present study systematically explores the expression patterns of OR genes in a large number of tissues and assesses the potential functional implication of such ectopic expression. Results We analyzed the expression of hundreds of human and mouse OR transcripts, via EST and microarray data, in several dozens of human and mouse tissues. Different tissues had specific, relatively small OR gene subsets which had particularly high expression levels. In testis, average expression was not particularly high, and very few highly expressed genes were found, none corresponding to ORs previously implicated in sperm chemotaxis. Higher expression levels were more common for genes with a non-OR genomic neighbor. Importantly, no correlation in expression levels was detected for human-mouse orthologous pairs. Also, no significant difference in expression levels was seen between intact and pseudogenized ORs, except for the pseudogenes of subfamily 7E which has undergone a human-specific expansion. Conclusion The OR superfamily as a whole, show widespread, locus-dependent and heterogeneous expression, in agreement with a neutral or near neutral evolutionary model for transcription control. These results cannot reject the possibility that small OR subsets might play functional roles in different tissues, however considerable care should be exerted when offering a functional interpretation for ectopic OR expression based only on transcription information.

    Ectopic pregnancy is commonly seen as a differential diagnosis of first-trimester vaginal bleeding. Often the diagnosis is made based on a combination of exam findings, transvaginal ultrasound, and a positive pregnancy test. Our case describes a patient with a history of ectopic pregnancy treated with methotrexate and serial human chorionic gonadotropin measurements that were decreasing appropriately. At the time of evaluation, her urine pregnancy test was negative; however, she was confirmed to have a ruptured tubal ectopic pregnancy. This case highlights the variable presentation of ectopic pregnancies and the importance of combining exam findings with ultrasound and laboratory results.

    BACKGROUND An ectopic pregnancy is a pregnancy which occurs outside of the uterine cavity, and over 98% implant in the Fallopian tube. Tubal ectopic pregnancy remains the most common cause of maternal mortality in the first trimester of pregnancy. The epidemiological risk factors for tubal ectopic pregnancy are well established and include: tubal damage as a result of surgery or infection (particularly Chlamydia trachomatis), smoking and in vitro fertilization. This review appraises the data to date researching the aetiology of tubal ectopic pregnancy. METHODS Scientific literature was searched for studies investigating the underlying aetiology of tubal ectopic pregnancy. RESULTS Existing data addressing the underlying cause of tubal ectopic pregnancy are mostly descriptive. There are currently few good animal models of tubal ectopic pregnancy. There are limited data explaining the link between risk factors and tubal implantation. CONCLUSIONS Current evidence supports the hypothesis that tubal ectopic pregnancy is caused by a combination of retention of the embryo within the Fallopian tube due to impaired embryo-tubal transport and alterations in the tubal environment allowing early implantation to occur. Future studies are needed that address the functional consequences of infection and smoking on Fallopian tube physiology. A greater understanding of the aetiology of tubal ectopic pregnancy is critical for the development of improved preventative measures, the advancement of diagnostic screening methods and the development of novel treatments.

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    Ectopic Cushing syndrome due to ACTH secretion from metastatic medullary thyroid cancer (MTC) is associated with significant morbidity and mortality. The aim of the study was to describe the first case of Cushing syndrome associated with MTC in a pediatric patient and the successful reversal of Cushing syndrome with tyrosine kinase inhibitor (vandetanib) therapy. A 17-year-old Brazilian adolescent presented with metastatic MTC and associated ACTH-dependent ectopic Cushing syndrome in the context of multiple endocrine neoplasia type 2B. When the patient was treated with the tyrosine kinase inhibitor vandetanib, rapid decrease in serum cortisol and improvement of clinical symptoms were observed. We describe the first pediatric case of clinical and biochemical improvement of paraneoplastic MTC-related Cushing syndrome after treatment with vandetanib. Vandetanib and possibly other tyrosine kinase inhibitors may be a novel beneficial option in patients with neuroendocrine tumor-related ectopic Cushing syndrome.

    de Quervain thyroiditis is a self-limited inflammatory disorder of the thyroid gland. It is an uncommon disease in adults and very rare in children. Fritz de Quervain, a Swiss surgeon, who was an authority on thyroid disease, described the unique pathology of this disease. Granulomatous changes with giant cells in thyroid tissue are the pathological findings. Viral infection in genetically predisposed individuals has been proposed as the pathogenesis of the disease. Clinical hallmarks for the diagnosis are painful thyroid enlargement, elevated erythrocyte sedimentation rate, and C-reactive protein as well as decreased uptake of the thyroid gland on thyroid scintigraphy. In addition, thyrotoxicosis is present in about 50% of cases in early phase of the disease. Serum thyroglobulin level is usually elevated. Only symptomatic treatment with analgesics is usually required for pain relief. Glucocorticoid therapy may be used in severely ill patients. de Quervain thyroiditis is generally completely resolved without complications in 6-12 months. However, permanent hypothyroidism and recurrent disease have been reported in some patients.

    Thyroid nodules and thyroid abnormalities are common findings in the general population. Ultrasonography is the most important imaging tool for diagnosing thyroid disease. In the majority of cases a correct diagnosis can already be made in synopsis of the sonographic together with clinical findings and basal thyroid hormone parameters and an appropriate therapy can be initiated thereafter. A differentiation of hormonally active vs. inactive nodes, and in particular benign vs. malignant nodules is sonographically, however, not reliably possible. In this context, radioscanning has its clinical significance predominantly in diagnosing hormonal activity of thyroid nodules. Efforts of the past years aimed to improve sonographic risk stratification to predict malignancy of thyroid nodules through standardized diagnostic assessment of evaluated risk factors in order to select patients, who need further diagnostic work up. According to the "Breast Imaging Reporting and Data System" (BI-RADS), "Thyroid Imaging Reporting and Data Systems" (TI-RADS) giving standardized categories with rates of malignancy were evaluated as a basis for further clinical management. Recent technological developments, such as elastography, also showpromising data and could gain entrance into clinical practice. The ultrasound-guided fineneedle aspiration is the key element in the diagnosis of sonographically suspicious thyroid nodules and significantly contributes to the diagnosis of malignancy versus benignity.

    The topic "Thyroid and Radiation" is both an old and a new area to be solved by human beings. The thyroid is an organ that is usually susceptible to exposure to ionizing radiation, both by virtue of its ability to concentrate radioiodine (internal radiation) and by routine medical examination: Chest X-ray, Dental X-ray, X-irradiation of cervical lymphnodes etc. (external radiation). Iodine-131 is widely used for the therapy of Graves' disease and thyroid cancers, of which the disadvantage is radiation-induced hypothyroidism but not complications of thyroid tumor. The thyroid gland is comparatively radioresistant, however, the data obtained from Hiroshima, Nagasaki and Marshall islands indicates a high incidence of external radiation-induced thyroid tumors as well as hypothyroidism. The different biological effects of internal and external radiation remains to be further clarified. Interestingly, recent reports demonstrate the increased number of thyroid cancer in children around Chernobyl in Belarus. In this review, we would like to introduce the effect of radiation on the thyroid gland at the molecular, cellular and tissue levels. Furthermore the clinical usefulness of iodine-131, including the safety-control for radiation exposure will be discussed.

    Ectopic preganacies are unsuccessful pregnancies that result from implantation of fertilized ovum occurring in an aberrant area. Aside from an emergency case, the early diagnosis of ectopic pregnancy is very difficult particularly in a case with insidious onset and mild clinical manifestations. Early diagnosis not only reduces the danger, but also simplifies the management of ectopic pregnancy. Ultrasonography has been an indispensable diagnostic tool in Obstetrics and Gynecology. In the authors' experience, clinical suspected ectopic pregnancy was one of the common indications for performing ultrasonography. Since Kobayashi at al. reported the appearances of ectopic pregnancy utilizing bistable B-scan ultrasonography, the ultrasonic findings of ectopic pregnancy have been reported by many authors. But, its accuracy and reliability in the diagnosis of ectopic pregnancy are still open to controversy. The authors studied 65 cases of clinically suspected ectopic pregnancy with Picker 80 L gray scale ultrasonography from Aug. 1982 to June. 1983. There were 29 confirmed cases, of which 15 were proved to have ectopic pregnancy and 14 were proved to have diseases other than ectopic pregnancy by surgical and histopathological study or by laparoscopy and follow up study. 29 confirmed cases were reviewed. The results were as follows: 1. Among 15 ectopic pregnancies, there were 12 ampullary pregnancies, 2 isthmic pregnancies and 1 interstitial pregnancy. Among 14 cases of no ectopic pregnancy, there were 5 intrauterine pregnancies, 3 myoma uteri, 2 P.I.D., and 1 case of dermoid cyst, cystic teratoma, H-mole and tubal hematoma due to previous tuball ligation, respectively. 2. The age distribution of ectopic pregnancy was from 22 to 41 years. The common clinical manifestations of ectopic pregnancy were lower abdominal pain (73.3%), vaginal spotting or bleeding (73.3%) and amenorrhea (66.7%). 3. Positive result of urine immunologic pregnancy test was 28.6% in ectopic

    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 current prevalence of thyroid cancer in women is high. Likewise, other cancers and thyroid cancer have been based on the TNM classification system. Staging of thyroid cancer has an important role in determining the extent of surgical excision and lymph node dissection, planning the adjuvant therapy after surgery and predicting the recurrence rate and the prognosis of patients. Ultrasonography is the basic imaging modality to identify the tumor size and the extent of lymph node metastasis. More recently, computed tomography, magnetic resonance imaging and positron emission tomography provide additional help for the staging of thyroid cancer. So, this article describes the 7th edition of the TNM staging of thyroid cancer, as proposed by the American Joint Committee on Cancer, and the details of radiologic evaluation of the T, N and M stages

    Constitutive Fas ligand (FasL) expression by specialized cells in the body participates in the immune privilege status of tissues containing these cells. This property has been used to prevent rejection of allogeneic grafts. Nevertheless, the mechanism responsible for such protection has not been fully elucidated. Unfortunately, grafting of FasL transgenic (TG) tissues has been unsuccessful. We have generated TG mice expressing FasL (soluble + membrane bound) on thyroid follicular cells (TFC), and used them to show that ectopic FasL expression prevents thyroid allograft rejection. FasL expression on TFC led to markedly decreased anti-allogeneic, cytotoxic, and helper T lymphocyte activities. The alloantibody response in TG thyroid recipients was either completely inhibited or switched toward a T2-Ab response. Surprisingly, the beneficial effect of FasL on TG thyroid grafts was abolished by host CD4(+) T cell depletion. Host CD8(+) T cell depletion improved nontransgenic (NTG), but not TG graft survival. Altogether, our results suggest that FasL-induced tolerance is concomitant with a move away from a T1 type response, and a CD4 T cell-mediated regulation of the allocytotoxic T cell response. These results were dependent upon the level of FasL expression on TFC, in that low expression of FasL led to a less marked effect compared with the effect observed with high expression of FasL. These results provide some insight into the role of FasL in regulating destructive alloimmune responses in the case of whole organ grafting, and they have important implications for the development of FasL-based immunotherapy in organ transplantation.

    Full Text Available Background & Objectives: Ectopic pregnancy is one of the common medical emergencies encountered in the clinical practice. Confirmation of diagnosis is usually done by urine pregnancy test and transabdominal sonography. Thus, the present study is carried out to determine the role of transabdominal ultrasonography in the diagnosis of ectopic pregnancy by comparing the ultrasonography findings with that of operative and histopathology and to evaluate clinical profile of the women with confirmed ectopic pregnancy. Materials & Methods: Transabdominal ultrasound record of patients referred for first trimester ultrasound, from January 2008 to December 2015, at radiology department of Kist medial college teaching hospital were reviewed to identify patients with ectopic pregnancy. Among these patients those who underwent surgery and histopathology confirmed ectopic pregnancies were identified and their medical records were retrieved. Ultrasound and clinical profile were recorded and statistically analyzed. Results: There were 19 patients with ultrasound diagnosis of ectopic pregnancy among 1480 first trimester ultrasound record. Among these patients, ectopic pregnancy was confirmed on 18 patients. Ultrasound diagnosis included adnexal mass with pelvic fluid in 15 (83.3% patients and pelvic fluid without adnexal mass in 4 (16.7% patients. The study result revealed that sensitivity of transabdominal ultrasonography was 100% and specificity was 99.9%. Positive predictive value and negative predictive value of transabdominal ultrasonography was 94% and 100%.Conclusion: The transabdominal ultrasound accurately diagnose ruptured ectopic pregnancy.JCMS Nepal. 2016;12(1:1-4.

    Full Text Available BACKGROUND Thyroid diseases and diabetes mellitus are the most common endocrine diseases during pregnancy. Internal Medicine doctors could be involved in the management of pregnant women affected by thyroid diseases, in particular if an Endocrine Unit lacks in the hospital; it is mandatory that they have the skills to cope with these diseases. METHODS In this work authors describe the most common thyroid abnormalities that can occur during pregnancy: hypothyroidism (clinical and subclinical, hyperthyroidism (clinical and sub-clinical, autoimmune thyroiditis (in particular the so called post-partum thyroiditis, nodular diseases and cancer. They discuss moreover the peculiar pathophysiologic mechanisms by which these diseases appear, the diagnostic tools and the therapies, according to their own experience and the more recent international guidelines. RESULTS AND CONCLUSIONS It is important to evaluate thyroid function tests before and during pregnancy, at 16th and 28th gestational week; it is mandatory to cure also the “sub-clinical” hypothyroidism during pregnancy, when TSH level are higher than 5 μIU/mL; the optimal dose of levo-thyroxine during pregnancy is, average, 30-50% higher than that used before pregnancy; it is not correct to treat mild or sub-clinical hyperthyroidism; propylthyouracil is the best drug to treat hyperthyroidism during pregnancy; the post-partum thyroiditis is generally transient, so that a careful monitoring of thyroid function is advisable, in particular after 9-12 months of therapy; thyroid cancer, if discovered during pregnancy, generally has no negative effects on the outcome of the pregnancy; it would be better to treat surgically thyroid cancer during the last trimester of the pregnancy.

    2014-01-01

    Haemorrhage after thyroid surgery is rare, but if it occurs it is a life-threatening condition necessitating emergency surgery. The aim of this study was to evaluate prevalence and risk factors of haemorrhage after thyroid surgery. A retrospective analysis was undertaken in a group of 8931 consecutive patients with various thyroid diseases treated in 2004-2013 at our institution. Potential risk factors for postoperative haemorrhage after thyroid surgery were analysed using logistic regression model. Haemorrhage after thyroid operation necessitating emergency surgery occurred in 40 (0.45%) of 8931 patients. None of the patients died within the perioperative period. Bleeding occurred within first 24 hours following surgery in 38 (95%) patients, and in the remaining 2 (5%) patients in more than 24 hours after initial surgery. The following risk factors for bleeding after thyroid operation were identified: male sex (OR 3.618; 1.762-7.430; p or = 70 years (OR 3.052; 1.275-7.304; p = 0.012), surgery for hyperthyroidism (OR 2.873; 1.511-5.462; p = 0.001), smoking (OR 2.855; 1.502-5.428; p = 0.001), subtotal thyroidectomy in contrast to total thyroidectomy or lobectomy (OR 2.853; 1.356-6.004; p=0.006), and thyroid operation undertaken by resident in training in general surgery (OR 2.596; 1.393-4.837; p = 0.003). Haemorrhage after thyroid operation necessitating emergency surgical intervention occurs most frequently within first 24 hour following surgery. Hence, for safety reasons a minimum of 24-hour hospital stay is recommended in all patients with risk factors for postoperative bleeding after thyroid operation. Quality monitoring of thyroid surgery should include also risk factors for postoperative bleeding.

    The incidence of ectopic pregnancy is approximately 2% of all pregnancies, and it remains the leading cause of death in early pregnancy. Over 95% of ectopic pregnancies are tubal pregnancies, and the remainders are nontubal pregnancies. The highest risk factor for ectopic pregnancy is a previous tubal pregnancy followed by previous tubal surgery, tubal sterilization, tubal pathology, and current intrauterine device use. The apparent increase in the incidence of nontubal ectopic pregnancy including heterotopic pregnancy may be attributed to the increasing number of pregnancies because of in vitro fertilization treatment. In most cases, an ectopic pregnancy can be treated medically with a single dose of methotrexate. Surgical treatment is still needed in women who are hemodynamically unstable and in those who do not fulfill the criteria for methotrexate treatment. Usually surgical treatment can be performed by laparoscopy and in some cases by hysteroscopy. Laparotomy is rarely needed even in women with intraperitoneal bleeding.

    Full Text Available Ovarian ectopic pregnancy (OEP is one of the rarest forms of nontubal ectopic pregnancies. Less than 1% of ectopic pregnancies are primary OEP. Exact etio-pathogenesis and predisposing factors for OEP are not yet well understood. Review of literature suggests its possible association with conditions like tubal sterilization, intrauterine contraceptive device (IUCD, IVF-ET in patients with bilateral salpingectomy etc. Clinical and radiological presentation often mimics like tubal ectopic pregnancy, making preoperative diagnosis difficult for clinicians. Thus, correct diagnosis can be made only intraoperatively using Speigelberg's criteria followed by histopathological confirmation. Treatment includes wedge resection of affected ovarian tissue or salpingo-oophorectomy in selected cases. We present a case series of primary ruptured ovarian ectopic pregnancy with no identifiable risk factors with inconclusive radiological diagnosis.

    Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation. Mutiple radiological examinations detected bilateral adrenal atrophy. When the images were investigated in a more expanded scope, a 3.0×3.5×5.3 cm mass was detected in the anterior of left renal hilum and left renal vein. The mass was successfully resected with intraoperative endoscopy and pathological evaluation revealed an ectopic adrenal tumor. It is suggested that when the endocrinlogically confirmed adrenal neoplasm could not be well and definitely localized, the possibility of ectopic adrenal should be presumed and further radiography examinations should extend to the field where ectopic adrenal usually presents.

    Full Text Available Due to the likelihood of physical and mental health impacts following the unprecedented accident at the Fukushima Dai-ichi Nuclear Power Plant, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey to assist in the long-term health management of residents. This included thyroid ultrasound examination for all children in Fukushima. For appropriate evaluation of ultrasound screening of the thyroid, it is important to understand its reference data of thyroid findings in children in general. In order to analyze the frequencies of specific thyroid findings, we conducted ultrasound screening of the thyroid by the same procedures as used in Fukushima in 4,365 children, aged 3 to 18 years, from three Japanese prefectures. Overall, thyroid cysts were identified in 56.88% and thyroid nodules in 1.65% of the participants. Thyroid cysts and nodules with a maximum diameter of more than 5 mm were identified in 4.58% and 1.01%, respectively, and age-adjusted prevalences were 3.82% and 0.99%, respectively. Although the prevalence of cysts and nodules varied among the examination areas, no significant differences were observed among the three examination areas in the prevalence of cysts and nodules with a maximum diameter of more than 5 mm. Also, the prevalence of thyroid cysts and nodules, especially those with a maximum diameter of more than 5 mm, significantly increased with age, and showed a female predominance. We also identified ectopic thymus (1.95%, diffuse goiter (1.40%, ultimobranchial body (0.73%, lymph node swelling (0.21% and thyroid agenesis (0.05%. This is the first ultrasound description of the age-adjusted prevalence of thyroid cysts and nodules, or of the prevalence of abnormalities other than cysts and nodules, such as ectopic thymus, in relation to age, in the general Japanese child population. We contend that this can provide relevant information for the Fukushima Health Management Survey and future

    Ultrasound examination of the thyroid offers an accurate morphological picture and the possibility of comparing objectively the size of lobes and lesions over long periods. Cysts and calcifications, mostly benign, are readily recognized. Neoplastic lesions in our series were all less reflective than normal thyroid tissue. But so were the majority of benign nodules. In hyperthyroidism, subacute thyroiditis and Hashimoto's thyroiditis, the thyroid tissue is much less echogenic than in the normal gland.

    Full Text Available A 36-year-old woman with 3 prior C-sections is diagnosed with a caesarean scar ectopic pregnancy. Despite receiving intramuscular and transvaginal methotrexate injection 2 months before presentation, the beta human chorionic gonadotropin was recorded to be 73 mIU/mL at the time of encounter. The patient complained of vaginal bleeding with a significant drop in hematocrit from 40% to 33%. Transvaginal ultrasound confirmed retroplacental hemorrhage and because of the patient's desire to retain fertility, interventional radiology was consulted to perform an uterine artery embolization. The uterine artery embolization was successful in achieving hemostasis and resulted in a decrease of betaHCG to 46 on postprocedure day 1 to <1 mIU/mL by postoperative week 3.

    Full Text Available Primary ovarian pregnancy is one of the rarest varieties of ectopic pregnancies. Patients frequently present with abdominal pain and menstrual irregularities. Intrauterine devices have evolved as probable risk factors. Preoperative diagnosis is challenging but transvaginal sonography has often been helpful. A diagnostic delay may lead to rupture, secondary implantation or operative difficulties. Therefore, awareness of this rare condition is important in reducing the associated risks. Here, we report two cases of primary ovarian pregnancies presenting with acute abdominal pain. Transabdominal ultrasonography failed to hint at ovarian pregnancy in one, while transvaginal sonography aided in the correct diagnosis of the other. Both cases were confirmed by histopathological examinations and were successfully managed by surgery.

    Full Text Available This work analyzes the data of cont emporary scientific literature regarding the ectopic mineralization in the prostate gland, its pathogenetic features are considered. The scientific literature of recent decades gives grounds to assert that the processes of concrement formation in the prostate gland are influenced by many factors, pathological mineralization can be realized by different mechanisms. They include chronic inflammation, stagnation fract ions in gland, reflux of urine from the urethra at intravesicle obstruction, malformation of prostate and seminal vesicles, specific inflammation, polymorphism of gene protein inhibitors of calcification. These mechanisms are interconnected, each of them may participate in the overall development of concrement fo rmation in the prostate. In recent years, due to improved instrumental diagnosis we observe a significant increase of the number of patients, who were found with pathogenic prostate gland biol iths, which requires more detailed and in-depth study of the mechanisms of mineral formation in the prostate.

In this review, we critically discuss the thyroid hormone formulations that are available and approaches to correct replacement therapy with thyroid hormone in primary and central hypothyroidism in different periods of life such as pregnancy, birth, infancy, childhood, and adolescence as well as in adult patients, the elderly, and in patients with comorbidities. Despite the frequent and long term use of l-T4, several studies have documented frequent under- and overtreatment during replacement therapy in hypothyroid patients. We assess the factors determining l-T4 requirements (sex, age, gender, menstrual status, body weight, and lean body mass), the major causes of failure to achieve optimal serum TSH levels in undertreated patients (poor patient compliance, timing of l-T4 administration, interferences with absorption, gastrointestinal diseases, and drugs), and the adverse consequences of unintentional TSH suppression in overtreated patients. Opinions differ regarding the treatment of mild thyroid hormone deficiency, and we examine the recent evidence favoring treatment of this condition. New data suggesting that combined therapy with T3 and T4 could be indicated in some patients with hypothyroidism are assessed, and the indications for TSH suppression with l-T4 in patients with euthyroid multinodular goiter and in those with differentiated thyroid cancer are reviewed. Lastly, we address the potential use of thyroid hormones or their analogs in obese patients and in severe cardiac diseases, dyslipidemia, and nonthyroidal illnesses.

    Full Text Available Ectopic breast is a congenital anomaly of the breast which can have varied presentations because of its different sites and pathologies arising from it. Lesions of ectopic breast tissue (EBT are commonly seen due to persistence of embryonic remnants along the milk line. They have also been reported from other sites like face, vulva, and perineum. They are prone to the same physiological and pathological alterations seen in the normal breast. Only 0.3% of breast carcinomas arise in the ectopic breast, whereas only a few cases of fibroadenoma have been reported at this site. We present a case of polymastia in a 21-year-old female in the inframammary region. We report two cases of fibroadenoma and carcinoma arising from EBT in the axilla of a 26 and 45-year females. Fibroadenoma was treated by simple excision while for carcinoma modified radical mastectomy was done followed by radiation and chemotherapy. Patient developed metastasis in the sternum. Carcinoma arising from EBT has a poorer prognosis and needs early diagnosis and treatment.

    Although patients with medullary thyroid cancer are known to present with paraneoplastic hormone production, this is much less common with papillary thyroid cancer. We present a patient with the cribriform morular variant of papillary thyroid cancer in association with familial adenomatous polyposis who developed a positive pregnancy test in the absence of known pregnancy. The patient had developed vaginal bleeding, and her laboratory testing was characterized by elevated serum human chorionic gonadotropin (β-hCG) concentrations, but negative qualitative urine results. After a thorough gynecological evaluation to exclude unexpected normal, ectopic, or molar pregnancy, we pursued an evaluation for other sources of β-hCG production. We showed that the elevated serum β-hCG concentrations were not the result of heterophile antibody interferences, and ultimately we proved that her recurrent tumor produced the ectopic β-hCG. This is the first report of β-hCG production by papillary thyroid cancer. Thus, the possibility of ectopic production of β-hCG by papillary thyroid cancer needs to be included in the differential diagnosis of elevated hCG concentration in the absence of pregnancy. This study of an unusual paraneoplastic syndrome highlights the importance of investigating discrepancies in the clinical laboratory. Copyright © 2014 Elsevier B.V. All rights reserved.

    Objective:To study the differences in superior thyroid artery and inferior thyroid artery blood flow spectrum parameters in subacute thyroiditis. Methods:A Total of 40 cases of patients with subacute thyroiditis and 40 cases of healthy volunteers were selected for study and enrolled in pathology group and control group respectively, color Doppler ultrasonography was conducted to detect peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery as well as resistance index (RI), and serum was collected to detect thyroid hormone contents, infection indexes and oxidative stress indexes. Results:Peak blood flow velocities Vmax of superior thyroid artery and inferior thyroid artery of pathology group were significantly higher than those of control group, and resistance index RI was not different from that of control group;FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA of pathology group were significantly higher than those of control group, and SOD and TAOC were significantly lower than those of control group;Vmax of superior thyroid artery and inferior thyroid artery were positively correlated with FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA, and negatively correlated with SOD and TAOC. Conclusion:Peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery in subacute thyroiditis are significantly accelerated, Vmax has good consistency with thyroid hormone contents, infection indexes and oxidative stress indexes, and it can accurately assess the severity of the disease.

    Results: Lower abdominal pain was most common presenting symptom of ectopic pregnancy in 96% cases. The classical triad of symptoms (amenorrhea, abdominal pain and vaginal bleeding was present in only 28% cases. PID contributed 24% cases and previous abortion contributed 28% cases indicating these two as the common risk factors. Ampulla was the commonest site for ectopic pregnancy, in 52% cases. Salpingostomy performed mainly at this site. In 6% cases ectopic pregnancy in infundibulum were treated with fimbrial expression and fimbriectomy. 22% patients were managed medically (methotraxte. These were the cases having unruptured ectopic pregnancy and ectopic mass <4 cm. Laparoscopy was done in 34% cases, in 2 cases it was converted to laparotomy. While open laparotomy was done in 40% cases. Conclusions: Ectopic pregnancy is a treatable problem. Ultrasonography plays central role in the diagnosis and management. Mode of therapy is determined by a combination of clinical symptoms, sonography findings and serum b-HCG values. Surgical management is still a cornerstone of management of ectopic pregnancy. But now scope of medical and laparoscopic management is also there. In recent years laparotomy has been replaced by laparoscopic surgery which is more conservative, minimally invasive and less time consuming which leads to quick recovery.

    To evaluate the ultrasound findings of ectopic pregnancy in the group of women examined in our department transvaginal ultrasound. Analysis of ectopic pregnancy cases covers the period from 1. 8. 2012. to 31. 9. 2015. We introduced several case studies. Retrospective analysis. Department of Gynecology and Obstetrics, Hospital Jindrichuv Hradec. The methodology is based on a retrospective evaluation of the history, laboratory and ultrasound findings in a group of 30 patients with ectopic pregnancy. At the first visit were diagnosed by transvaginal ultrasound 82% ectopic pregnancy. A patological adnexal mass was visualised in 84% cases. A negative ultrasound finding was observed in 16% cases. The results of our group of patients are more or less comparable with other studies. We recorded the same risk factors for ectopic pregnancy. Most ectopic pregnancies can be diagnosed at the first examination before starting treatment and treated at an early stage. Transvaginal ultrasound is the "gold standard" diagnostic tool of choice in the diagnosis of ectopic pregnancy in combination with the dynamics of serum levels β-hCG..

    Temporary ectopic implantation has been performed in clinical practice to salvage devascularized amputated tissues for delayed replantation purpose. In this study, we established a series of segmental forelimb ectopic implantation models in rats, including forelimb, forearm, forepaw, digit, and double forelimbs, to mimic the clinical context. Time of amputated limbs harvesting in donors and ectopic implantation process in recipients were recorded. Survival time and mortalities of recipients were also recorded. Sixty days after ectopic implantation, a full-field laser perfusion imager (FLPI) was used to detect the blood flow of amputated limbs and micro-CT imaging was used to examine bone morphological changes. Histological sections of amputated limbs were stained with hematoxylin and eosin to evaluate pathological changes. Implanted amputated limbs in all models achieved long term survival and there were no obvious morphological and histological changes were found according to results of micro-CT and histology study. Thus, a series of rat segmental forelimb temporary ectopic implantation models have been well established. To our knowledge, this is the first rodent animal model related to forelimb temporary ectopic implantation. These models might facilitate further research related to salvage, reconstruction and better aesthetic and functional outcome of upper extremity/digit in temporary ectopic implantation scenario.

    To evaluate the clinical features, aetiologic factors, challenging properties (such as radio opacity in Water's view in a patient with no sinusitis), signs and symptoms of the ectopic teeth in the maxillary sinus. Clinical symptoms and radiographic findings of 14 patients with ectopic teeth in the maxillary sinus were evaluated. Computed tomography (CT) and conventional radiographic images of maxillary sinus and clinical findings were compared with each other with regard to the final diagnosis. Water's view is inadequate to diagnose ectopic tooth in the maxillary sinus in some cases. Panoramic radiographs may be preferred before CT to evaluate the ectopic tooth in the maxillary sinus as structure of a tooth can be clearly detected on panoramic radiographs. Crowding was the most common aetiologic factor among the 14 cases. The patients with ectopic tooth in the maxillary sinus should be evaluated thoroughly by complete otorhinolaryngologic, intraoral examinations and proper diagnostic imaging procedures in order to avoid misdiagnosis of maxillary sinusitis. As the opacity of the maxillary sinus in Water's view due to ectopic tooth can be misinterpreted as maxillary sinusitis, patients who have sinusitis-like complaints and opacity of maxillary sinus in Water's view who are resistant to medical treatment should be evaluated with respect to the presence of ectopic tooth.

    Fungal pathogens are increasingly encountered after renal transplantation. Aspergillus causes significant morbidity and mortality in transplant patients. Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may be identical with that of subacute thyroiditis, in which hyperthyroidism features and painful thyroid are the prominent findings. Diagnosis can be ascertained by fine-needle aspiration of thyroid showing branching hyphae of Aspergillus. We describe a renal transplant patient who developed Aspergillus thyroiditis as part of a disseminated infection successfully treated with voriconazole.

    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.

    Background: Thyroid hemiagenesis is a rare congenital variant characterized by the lack of development of one thyroid lobe with no clinical manifestations. Methods: This study was performed to determine the prevalence and characteristics of thyroid hemiagenesis in a normal Japanese population. This cross-sectional study was performed from October 9, 2011, to April 30, 2015. In total, 299,908 children and young adults in the Fukushima Health Management Survey were examined to determine the presence of thyroid agenesis or hemiagenesis. Thyroid width, thickness, and length were measured in 292,452 of these subjects. Results: Thyroid agenesis was diagnosed in 13 subjects, and hemiagenesis was detected in 67 subjects (0.02%; 22.3/100,000 individuals). Although there was no significant sex-related difference (p = 0.067), the female:male ratio was 1.67:1.00. Females were significantly dominant in right hemiagenesis, while there was no difference in left hemiagenesis between males and females. The thyroid volumes at the 2.5th and 97.5th percentiles for age and body surface area were determined for each sex. Multivariate regression analysis showed that a large hemithyroid volume was independently associated with the presence of contralateral hemiagenesis (p thyroid hemiagenesis in the present study is in agreement with that reported in other countries. The prevalence of right hemiagenesis was higher in females, and the larger contralateral lobe in patients with rather than without hemiagenesis may have been caused by a compensatory feedback mechanism to prevent hypothyroidism. In addition, the prevalence of hemiagenesis, especially right hemiagenesis, may be affected by sex-related factors similar to those in patients with an ectopic thyroid gland. PMID:28657504

  17. Technique for the Laparoscopic Management of a Cornual Ectopic Pregnancy.

    To describe a technique for the laparoscopic management of a cornual ectopic pregnancy. Step-by-step explanation of the procedure using video (Canadian Task Force classification III). Cornual pregnancy is a rare form of ectopic pregnancy, accounting for up to 2% to 4% of all ectopic pregnancies, with a mortality range of 2.0% to 2.5%, and this accounts for 20% of all deaths caused by ectopic pregnancies. Both medical and surgical treatments have been reported. Although laparotomy hysterectomy and cornuectomy used to be the preferred surgical approaches, more cornual ectopic pregnancies are being managed with the laparoscopic approach through cornuostomy or cornuectomy in recent years. The main concern with surgical treatment is hemorrhage and the need for cornual reconstruction, which necessitate advanced laparoscopic skills and technique. In this video, we describe our technique for the treatment of a cornual ectopic pregnancy. We present the case of a 21-year-old G3P2002 (gravida 3 para 2002) with the finding of a right live cornual ectopic pregnancy with gestational age of 6 weeks on pelvic ultrasound along with an elevated human chorionic gonadotropin level at 7,192 and right pelvic pain. After counseling regarding treatment options, the patient agreed with proceeding with surgery and underwent a laparoscopic right cornuectomy. Her surgery was uneventful, and she was discharged home a few hours after surgery. She was completely recovered at her postoperative follow-up visit. Her serial serum human chorionic gonadotropin levels were followed until complete resolution a few weeks later. Laparoscopic cornuectomy is a safe and effective procedure for the management of cornual ectopic pregnancy. The use of hemostatic agents and suturing can help prevent hemorrhage and allows a safe removal of the ectopic pregnancy and repair of the uterine defect created. Copyright © 2016 AAGL.

    2010-01-01

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment.

    Ectopic teeth erupted in the maxillary sinus are rarely reported. Although the causes of eruption of a tooth into the maxillary sinus are unclear, some clinical conditions are suspected to be responsible, such as developmental disturbances (cleft palate), displacement of teeth by trauma, interventions or cyst, infection, genetic factors, crowding, and dense bone. Most cases of ectopic teeth in the maxillary sinus are asymptomatic and are occasionally diagnosed thanks to routine radiographic investigations.The aim of this article is to present and discuss the surgical management of an ectopic third molar in the roof of the maxillary sinus.

    Ectopic teeth occur because of failure of the first branchial cleft to close during development and are found mostly in young horses. Such dentigerous cysts are often located at the base of the ear, forming a notable swelling with a fistula, as it was the case with the two year old Iceland mare «Runa». In order to confirm the diagnosis, x-ray images were taken, which is also necessary to locate the ectopic tooth correctly. While operating, the whole cystic membrane should be removed and it is important to prevent adjacent nerves and blood vessels from damage. Prognosis for complete healing after removing an ectopic tooth is excellent.

    2007-01-01

    AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years.All of them were referred to our institute for treatment.Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease,inflammatory process, anemia, etc.RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%),and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

  17. The association between chronic lymphocytic thyroiditis and thyroid tumors.

    2002-04-01

    An association between lymphocytic thyroiditis and thyroid papillary carcinoma is still controversial. To assess the relationship, a histopathologic analysis of surgically resected thyroid tumors together with the frequency and severity of chronic lymphocytic infiltration of the thyroid among patients with follicular adenoma, follicular carcinoma, and papillary carcinoma was performed. The prevalence of lymphocytic infiltrate, which is indicative of autoimmune thyroiditis, was significantly higher in patients with papillary carcinoma (58%) than in patients with follicular carcinoma (20%) or follicular adenoma (14%). The lymphocytic infiltration within the tumor compared with the severity of thyroiditis in the nontumorous tissue. Therefore, the association between chronic lymphocytic thyroiditis and papillary carcinoma was confirmed. The possibility that an immunologic mechanism involved in the pathogenesis of papillary carcinoma stimulates lymphocytic infiltration in the thyroid tissue through an autoimmune mechanism is suggested.

    2012-02-01

    INTRODUCTION: Ectopic pituitary adenomas are extremely rare. We report a case of ectopic pituitary adenoma in the midline of the nasopharynx. This adenoma probably arose from the pharyngeal remnant of Rathke\\'s pouch. METHODS: We discuss a case of a lady who presented to our unit with 2 months history of dryness and sensation of lump in her throat and a long standing history of hypothyroidism. Examination of nasopharynx revealed a smooth and fluctuant midline mass. CT scan of nose and paranasal sinuses confirmed the midline mass with small defect communicating with the sphenoid sinus. An initial diagnosis of Thornwaldt\\'s cyst was made and she underwent upper aerodigestive tract endoscopy and marsupialization of the mass. Histopathological examination revealed ectopic pituitary adenoma. CONCLUSION: Ectopic pituitary adenoma is an important differential diagnosis for a midline nasopharyngeal mass. It is recommended that prior to surgical resection of midline nasopharyngeal mass biopsy is taken and MRI is performed.

    Twin ectopic pregnancy is a rare occurrence, with an estimated incidence of 1 in 20 000 spontaneous pregnancies. We describe a case of unilateral twin ectopic pregnancy in which the gravid fallopian tube showed no signs of tubal rupture despite marked tubal distension. A 25-year-old woman presented with clinical features suggestive of large right-sided tubal ectopic pregnancy. Serum β-human chorionic gonadotropin was 10 800 IU/mL. Laparotomy revealed markedly distended right fallopian tube. There was no hemoperitoneum. The tube contained twin gestational sacs. The crown-rump length of the embryos was 2 cm. The ectopic gestation was thus unique, in that despite marked tubal distension, the trophoblastic invasion was not significant to cause tubal rupture. There may be a role for medical management based on individual gestational sac size in selected cases of twin tubal pregnancy in which there is no evidence of hemoperitoneum.

    Ectopic eruption of maxillary canines can be associated with root resorption of adjacent teeth. This case report describes and discusses an interesting case of a 15-year-old girl with a Class III malocclusion and an impacted maxillary canine. Because of the unfavorable position of the ectopic canine and the severe root resorption of the maxillary left central and lateral incisors, the treatment options included extraction of the maxillary permanent canines. The mandibular first premolars were extracted to compensate for the Class III malocclusion. A panoramic radiograph taken earlier in the mixed dentition already indicated a possible eruption disturbance of the maxillary left permanent canine. The importance of early diagnosis of maxillary canine ectopic eruption is highlighted in this case report. The early identification of radiographic signs of an ectopic pathway of eruption should be followed by deciduous canine extraction to prevent canine retention and maxillary incisor root resorption.

    Full Text Available The present research provides analysis of results of preoperative examination of 680 patients with ectopic pregnancy depending on the range of surgical treatment. It has been shown that in case of progressive ectopic pregnancy the diagnostic significance of concentrations of human chorionic gonadotropin, transvaginal examination and laparos-copy depends on the duration of pregnancy. When the term of ectopic pregnancy is 3-4 weeks monitoring of p chorionic gonadotropin in blood serum (99.5%, transvaginal examination (58% and laparoscopy (78.5% are more informative. When the term of ectopic pregnancy is more than 4 weeks there is a high diagnostic value of monitoring p-subunit of chorionic gonadotropin (99.5%, transvaginal examination (68% and laparoscopy (99,5%. The research has proved that pregnancy period of 3-4 weeks is optimal for laparoscopy and other operations

    Full Text Available Background: Aim of current study was to evaluate the role of serum homocysteine and nitric oxide in the diagnosis of ectopic pregnancy. Methods: The study included 32 patients with ruptured ectopic, 29 miscarriage patients and 30 normal pregnant women as controls. Fasting plasma homocysteine, serum folate, vitamin B12 levels and nitric oxide levels were estimated at the time of admission. Results: Plasma homocysteine levels were significantly lower in patients with ectopic pregnancy than normal pregnancy. Nitric oxide levels were significantly lower in patients with abortion. Conclusions: Patients with abortion have decreased circulating nitric oxide levels in serum while those with ectopic pregnancies have decreased homocysteine levels.

    BACKGROUND: Obstructive jaundice caused by an intraductal hepatocellular carcinoma is a rare initial symptom. We report a rare case of an extrahepatic icteric type hepatocellular carcinoma. METHODS: A 75-year-old patient was admitted to our hospital because of obstructive jaundice 3 months after resection of multilocular hepatocellular carcinoma. A postoperative bile leakage was treated by placement of a decompressing stent in the common bile duct. Endoscopic retrograde choledochoscopy showed extended blood clots iflling the bile duct system and computed tomography revealed a local swelling in the common extrahepatic bile duct. The level of alpha-fetoprotein (AFP) was only slightly elevated but that of CA19-9 was dramatically increased. Cholangiography showed an intraductal iflling defect typical of a cholangiocellular carcinoma. RESULTS: Bile duct brushing cytology showed no cholangiocellular carcinoma but hepatocellular carcinoma cells in the extrahepatic bile duct. An extrahepatic bile duct resection was performed. Histological examination conifrmed the diagnosis of extrahepatic intraductal growth of hepatocellular carcinoma. CONCLUSION: Ectopic hepatocellular carcinoma is a rare but important differentially diagnosed of extrahepatic bile duct iflling defect.

    Tyson glands were described in the 17th century as modified sebaceous glands of the coronal sulcus of the penis. However, this description and other early texts supporting the existence of Tyson glands were not accompanied by illustrations. The existence of such glands has been passing through the literature without adequate graphical demonstration, which has contributed to controversial debates. Herein we present a case of a partial penectomy performed on a 65-year-old man with a squamous cell carcinoma of the penis. In this case we identified sebaceous glands as well as folliculosebaceous units in the coronal sulcus. We also comparatively examined 12 cases of partial penectomy to search for sebaceous glands or folliculosebaceous units in the coronal sulcus or the preputium. We found neither sebaceous glands nor folliculosebaceous units at the coronal sulcus or the mucosal aspect of the prepuce. We conclude that: (1) folliculosebaceous units are possible in the coronal sulcus, as the current case illustrates for the first time in literature and (2) the current case is an oddity, probably induced by the accompanying squamous cell carcinoma, and therefore it may represent an ectopic folliculosebaceous unit rather than an anatomic variation.

    Intramural pregnancy, a gestation completely surrounded by the myometrium located within the uterine wall with separation from the uterine cavity, is an extremely unusual form of pregnancy. Complications resulting from intramural pregnancy include inevitable uterine rupture with resultant hemorrhage and possible hysterectomy if diagnosis is not made early and treatment is not initiated. An asymptomatic patient was initially diagnosed with a missed abortion at approximately 6 weeks of gestation after a routine ultrasound. Suction curettage was performed approximately 1 month after the initial diagnosis. The pathology specimen failed to reveal placental villi. Ultimately, the diagnosis of intramural pregnancy was made via ultrasound and a computed tomography scan. She was treated with a single dose of systemically administered methotrexate. Over a period of 4 months, β-human chorionic gonadotropin levels trended downward; however, the intramural pregnancy failed to resolve completely, and a persistent mass remained. The intramural pregnancy was removed using the da Vinci laparoscopic procedure (Intuitive Surgical, Sunnyvale, CA). If the diagnosis of intramural ectopic pregnancy is made sufficiently early, conservative measures can be taken, which can preserve a patient's future fertility.

    A 34-year-old female presented to our clinic with a 1.5 year history of secondary amenorrhea and galactorrhea. Prolactin (PRL) level was found to be 151.89 ng/ml. Pituitary imaging was reported to be normal. An examination of the patient revealed that PRL level was still high so the dose of cabergoline was further increased and subsequently, bromocriptine was added to the treatment. There was no reduction in PRL levels in controls. A scanning was performed to look for an ectopic focus. Abdominal computerized tomography revealed a heterogenous mass lesion originating from the uterus. Octreotide scintigraphy was performed and we observed an involvement consistent with the mass in the uterus. The patient underwent abdominal total hysterectomy. PRL dropped to 0.4 ng/ml the next day after the operation. The pathology result was a low-grade malignant mesenchymal tumor. Prolactin was found to be immunohistochemically negative. However, galactorrhea disappeared postoperative and PRL levels are still low. Elevated levels of PRL, resistant to bromocriptine and cabergoline, rapidly returned to normal after hysterectomy, which obviously indicates that hyperprolactinemia was associated with the myoma of the uterus.

    Ectopic pregnancy occurs in 0.5-2% of all pregnancies. A double ectopic pregnancy is very rare and has the incidence of 1 in 725 ectopic pregnancies. We describe a case of a 30-year-old patient with double ectopic pregnancy located in tubas in spontaneous cycle--diagnosed and treated at the Gynecology and Obstetrics Hospital in Walbrzych. The patient had no risk factors for ectopic pregnancy. This case shows that even the diagnosis of an evident ectopic pregnancy cannot exclude the possibility of a double ectopic pregnancy.

    Ectopic infection with Paragonimus miyazakii was determined to be the cause of a subcutaneous inguinal mass in a 15-month-old, male, boar-hunting dog. On histologic examination, the mass comprised granulomatous panniculitis, intralesional adult trematodes and eggs, and lymphadenitis. Extrapulmonary paragonimosis in animals is rare. This appears to be the first report in a dog of ectopic P. miyazakii infection with mature trematodes and eggs that involved the inguinofemoral lymphocenter and surrounding subcutis.

    Endometriosis (ENDO) is a disorder in which vascularized growths of endometrial tissue occur outside the uterus. Its symptoms include reduced fertility and severe pelvic pain. Mechanisms that maintain the ectopic growths and evoke symptoms are poorly understood. One factor not yet considered is that the ectopic growths develop their own innervation. Here, we tested the hypothesis that the growths develop both an autonomic and a sensory innervation. We used a rat model of surgically induced EN...

    The purpose of this study was to investigate the diagnostic aspects, contributing conditions, and predictive key factors associated with ectopic eruption of maxillary second molars. This retrospective study evaluated the study models, lateral cephalographs, and panoramic radiographs of 40 adult subjects (20 men, 20 women) with bilateral ectopic eruption and 40 subjects (20 men, 20 women) with normal eruption of the maxillary second molars. Studied variables were analyzed statistically by independent t-tests, univariate and multivariate logistic regression analysis, followed by receiver-operating characteristic analysis. Tooth widths of bilateral lateral incisors, canines, and premolars were wider in the ectopic group, which resulted in greater arch lengths. The ANB angle and maxillary tuberosity distance (PTV-M1, PTV-M2) were smaller in the ectopic group. The long axes of the maxillary molars showed significant distal inclination in the ectopic group. The multivariate logistic regression analysis showed that three key factors-arch length, ANB angle, and PTV-M1 distance-were significantly associated with ectopic eruption of the second molars. The area under the curve (AUC) was the largest for the combination of the three key factors with an AUC greater than 0.75. PTV-M1 alone was the single factor that showed the strongest association with ectopic eruption (AUC = 0.7363). An increase in arch length, decrease in ANB angle, and decrease in maxillary tuberosity distance to the distal aspect of the maxillary first molar (PTV-M1) were the most predictive factors associated with ectopic eruption of maxillary second molars.

  17. Tergal and pleural structures contribute to the formation of ectopic prothoracic wings in cockroaches

    Elias-Neto, Moysés

    2016-01-01

    Wings were a fundamental morphological innovation for the adaptive radiation of insects, the most diversified group among all animals. Pterygote insects have two pairs of wings, the mesothoracic (T2) forewings and the metathoracic (T3) hindwings, whereas the prothorax (T1) is wingless. Using RNA interference approaches, we have found that the gene Sex combs reduced (Scr) determines the wingless identity of T1 in the cockroach Blattella germanica. Interference of Scr triggers the formation of ectopic wing structures in T1, which are formed from the expansion of the latero-posterior region of the pronotum, along with a contribution of the epimeron, a pleurite of T1. These data support the theory of a dual origin for insect wings, from pronotal (tergal origin theory) and pleural (pleural origin theory) structures and genes. PMID:27853616

    The diagnosis of Cushing disease is based on endocrinological pa-rameters, with no single test being specific. In some patients, dynamic thin-slice sellar magnetic resonance imaging fails to detect a pituitary tumor. The purpose of this study is to investigate the role of ectopic pituitary adenoma in this situation. In a retrospective chart review, 5 patients (6%) with ectopic adenomas were identified in 83 consecutive patients undergoing transsphenoidal surgery for adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas by 1 surgeon. In all 5 patients (all female, 32-41 years of age), an exclusively extrasellar ACTH-secreting adenoma was excised. Three adenomas were located in the cavernous sinus, 1 in the sphenoid sinus, and 1 in the ethmoidal cells. Histologically, none of the tumors showed signs of aggressiveness. Three of the 5 adenomas specifically expressed somatostatin receptor 5. In 4 patients with Cushing disease, postoperative remission was obtained, with 1 recurrence after 14 months. In the patient with Nelson syndrome, ACTH decreased from >800 to ectopic adenoma (positive for somatostatin receptor 5) in the ethmoidal cells turned out to be positive on gallium 68 DOTATATE positron emission tomography/computed tomography. The incidence of primarily ectopic ACTH-secreting adenomas in this series was 6%. In cases of negative MRI findings, an ectopic ACTH-secreting adenoma should be taken into account. 68 Ga DOTATATE positron emission tomography/computed tomography may identify ectopic pituitary adenomas. Hypophysectomy should always be avoided in primary surgery for CD.

    Historically, ectopic pregnancy was a life-threatening condition where diagnosis was possible only at post mortem or laparotomy and maternal mortality was up to 90%. The evolution in the management of ectopic pregnancy has meant that diagnosis can be made using non-invasive techniques with an aim to identify the ectopic gestation before tubal rupture. This enables health care professionals to offer management options that consider not only maternal mortality, but morbidity and fertility outcomes as well. In spite of this, diagnostic techniques and management options are not without limitations. Research is currently focused on new tests with a single diagnostic capability, diagnostic and treatment algorithms and safe methods of triaging patients. This article aims to review the current literature on the diagnosis and management of ectopic pregnancy and to formulate a pathway to help individualise care and achieve the best possible outcome.

    2015-01-01

    The risk factors and mechanisms for the development of postpartum thyroid dysfunction have been widely discussed. However data on patients suffered spontaneous or induced abortion during early pregnancy are scarce. To reveal the characteristics of thyroid dysfunction in women after an abortion in the first trimester of pregnancy. A total of 28 women (18 euthyroid, 10 with thyroid dysfunction), mean age 30.46 ± 1.01 years following abortion in the first trimester have been included in the study. Thyroid-stimulating hormone (TSH), free triiodthyronine (FT3), free thyroxine (FT4), thyreoglobulin antibodies (TgAb), thyroid peroxidase antibodies (TPOAb) were measured and ultrasound assessment of the thyroid was performed 3 and 9 months after the interruption of pregnancy. Hypothyroidism was found in 6 of the women with thyroid dysfunction and thyrotoxicosis--in 4. Clinical features of thyroid dysfunction were observed in 3 patients while in the remaining 7 cases, diagnosis was made on the basis of hormonal levels. Positive titers of thyroid autoantibodies were detected in the majority of the cases with functional disordes. In 6 patients thyroid dysfunction was transient and in 4 hormonal abnormalities persisted on by the 9th month after the abortion. The comparative analysis showed that the volume of the thyroid gland and the degree of hypoehogenicity were significantly higher in patients with thyroid dysfunction compared to euthyroid women. Thyroid dysfunction after abortion in the first trimester is mainly of autoimmune pathogenesis and its characteristics do not differ from those of postpartum thyroiditis. In the majority of patients these disorders are subclinical and may remain unrecognized. A close active follow up of patients at increased risk of functional thyroid disorders after an abortion is required in order to prevent morbidity and identify the cases developing permanent thyroid dysfunction.

    In humans, there is a significant decrease in serum T(3) and increase in rT(3) at different time points after myocardial infarction, whereas serum TSH and T(4) remain unaltered. We report here a time course study of pituitary-thyroid function and thyroid hormone metabolism in rats subjected to myocardial infarction by left coronary ligation (INF). INF- and sham-operated animals were followed by serial deiodination assays and thyroid function tests, just before, and 1, 4, 8, and 12 wk after surgery. At 4 and 12 wk after INF, liver type 1 deiodinase activity was significantly lower, confirming tissue hypothyroidism. Type 3 deiodinase (D3) activity was robustly induced 1 wk after INF only in the infarcted myocardium. Reminiscent of the consumptive hypothyroidism observed in patients with large D3-expressing tumors, this induction of cardiac D3 activity was associated with a decrease in both serum T(4) ( approximately 50% decrease) and T(3) (37% decrease), despite compensatory stimulation of the thyroid. Thyroid stimulation was documented by both hyperthyrotropinemia and radioiodine uptake. Serum TSH increased by 4.3-fold in the first and 3.1-fold in the fourth weeks (P Thyroid sodium/iodide-symporter function increased 1 wk after INF, accompanying the increased serum TSH. We conclude that the acute decrease in serum T(4) and T(3) after INF is due to increased thyroid hormone catabolism from ectopic D3 expression in the heart.

    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.

    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.

    Thyroid disease is common in younger women and may be a factor in reproductive dysfunction. This probably only applies to severe cases of hyper- or hypothyroidism. Once adequately treated, neither of these disorders significantly impacts on fertility. The key is to recognize and to treat thyroid disorders in the reproductive-age woman before conception. Thyroxine therapy and even antithyroid drug therapy should be continued during pregnancy as necessary. Pregnancy is a euthyroid state that is normally maintained by complex changes in thyroid physiology. The fetal and neonatal hypothalamic-pituitary-thyroid system develops independently, but it may be influenced by thyroid disease in the mother. Early pregnancy is characterized by an increase in maternal T4 secretion stimulated by hCG and an increase in TBG, resulting in the elevated total serum T4 in pregnancy. The debate continues as to whether maternal T4 is important in early or late fetal brain development. If so, the physiologic changes in thyroid hormone secretion and transport in early pregnancy would help to ensure that a sufficient amount of thyroid hormone was available. There is new evidence in human subjects that substantial maternal T4 can cross the placenta during pregnancy, and this may be particularly important when fetal thyroid function is compromised as a result of congenital hypothyroidism. Maternal and fetal/neonatal outcomes in pregnancy are adversely affected if severe hypothyroidism is undiagnosed or inadequately treated. Thyroid function tests should be obtained during gestation in women taking T4 and appropriate dose adjustments should be made for TSH levels outside a normal range. The TSH-receptor blocking antibodies from the mother are a recognized cause of congenital hypothyroidism in the fetus and neonate that can be permanent or transient. If neonatal hypothyroidism is detected through neonatal screening programs, and prompt and adequate T4 replacement therapy is instituted as soon as

    Epithelial-mesenchymal transition (EMT), a crucial step in disease progression, plays a key role in tumor metastasis. N-cadherin, a well-known EMT marker, acts as a major oncogene in diverse cancers, whereas its functions in thyroid cancer remains largely unclear. This study was designed to explore the biological roles and related molecular mechanism of N-cadherin in thyroid tumorigenesis. Quantitative RT-PCR (qRT-PCR) and immunohistochemistry assays were used to evaluate N-cadherin expression. A series of in vitro studies such as cell proliferation, colony formation, cell cycle, apoptosis, migration and invasion assays were performed to determine the effect of N-cadherin on malignant behavior of thyroid cancer cells. Our results showed that N-cadherin was significantly upregulated in papillary thyroid cancers (PTCs) as compared with non-cancerous thyroid tissues. N-cadherin knockdown markedly inhibited cell proliferation, colony formation, cell migration and invasion, and induced cell cycle arrest and apoptosis. On the other hand, ectopic expression of N-cadherin promoted thyroid cancer cell growth and invasiveness. Mechanically, our data demonstrated that tumor-promoting role of N-cadherin in thyroid cancer was closely related to the activities of the MAPK/Erk, the phosphatidylinositol-3-kinase (PI3K)/Akt and p16/Rb signaling pathways in addition to affecting the EMT process. Altogether, our findings suggest that N-cadherin promotes thyroid tumorigenesis by modulating the activities of major signaling pathways and EMT process, and may represent a potential therapeutic target for this cancer.

    Full Text Available Context: Ectopic Thyroid Gland (ETG is known to be the most common form of thyroid dysgenesis in children with permanent congenital hypothyroidism (CH. Recent reports indicate that agenesis or hypoplasia of thyroid gland may be commoner as compared to ETG in thyroid dysgenesis (TD. There is limited information available on the proportion of different variants of TD in Indian children. Aim: To characterize the different TD variants in a cohort of North Indian children with TD. Settings and Design: Endocrinology Unit of a large Multispecialty Pediatrics Center located in North India. Retrospective review of clinical records of children with CH due to TD diagnosed between April 2004 and March 2014. Results: Diagnoses of TD in 94 children (48 boys and 46 girls were based on combined scanning with high-resolution ultrasonography, and technetium-99m pertechnetate thyroid scintigraphy. Thyroid agenesis, ectopia and hypoplasia were diagnosed in 74 (78.7%, 14 (14.8% and 6 (6.4% patients respectively. The mean initial serum total T4 and thyroid stimulating hormone concentrations at diagnosis were 3.03 ± 2.88 μg/dL (range 0.01-8.9 and 284.52 ± 300.67 mIU/L (range 10.03-1159.0 respectively. Patients with ETG were older at the time of diagnosis as compared to patients with hypoplasia or ectopia. The mean duration of follow-up was 3.7 ± 2.85 years (range 3 months-10 years. Conclusions : Thyroid agenesis was the most common form of TD in our children with permanent CH. Hypoplasia and ectopia were uncommon. Female preponderance, noted in many previous reports, was not seen in our patients with TD.

    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.

    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.

    Differentiated thyroid carcinoma (DTC) is the most common endocrine malignancy. Surgical removal with radioactive iodine therapy is recommended for recurrent thyroid carcinoma, and the postsurgical thyroid removal is critical. This study evaluated the clinical values of radiofrequency ablation (RFA) in the postsurgical thyroid removal for DTC. 35 DTC patients who had been treated by subtotal thyroidectomy received RFA for postsurgical thyroid removal. Before and two weeks after RFA, the thyroid was examined by ultrasonography and (99m)TcO4 (-) thyroid imaging, and the serum levels of free triiodothyronine (FT3), free thyroxin (FT4), thyroid stimulating hormone (TSH) and thyroglobulin (Tg) were detected. The efficacy and complications of RFA were evaluated. Results showed that, the postsurgical thyroid removal by RFA was successfully performed in 35 patients, with no significant complication. After RFA, the average largest diameter and volume were significantly decreased in 35 patients (P > 0.05), and no obvious contrast media was observed in ablation area in the majority of patients. After RFA, the serum FT3, FT4 and Tg levels were markedly decreased (P RFA, radioiodine concentration in the ablation area was significantly reduced in the majority of patients. The reduction rate of thyroid update was 0.69±0.20%. DTC staging and interval between surgery and RFA had negative correlation (Pearson coefficient = -0.543; P = 0.001), with no obvious correlation among others influential factors. RFA is an effective and safe method for postsurgical thyroid removal of DTC.

    It is well-known that the thyroid hormones are associated with a number of aspects of the human reproduction. Both states, hyperthyroidism and hypothyroidism, have significant effect on the estrogen and androgen metabolism, the menstrual function and on fertility. The role of thyroid hormones (TH) during infertility has been little exploited. Interesting facts are that TH deficiency is more common in women with polycystic ovary syndrome (PCOS) and in certain cases with unexplained infertility. There are very few studies on the effect and paracrine regulation of TH and its receptors in the female reproductive tract. This report provides an overview of the most common thyroid disorders and their impact on ovarian function and reproductive performance in women as well as in cases with infertility and the implementation of assisted reproductive technologies (ART).

    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.

    Full Text Available The focus of the present review article is on thyroid dysfunctions which can be hypo or hyper thyroidism. Along with the ongoing allopathic treatment options, one can go for the alternative therapies or natural cures. Various nutritional supplements including iodine, botanicals like guggul and many more play an effective role in the management of thyroid dysfunction apart from the pharmaceuticals like synthetic T3 and T4 hormones and procaine thyroid. Along with these, homeopathy and yoga are equally important. The discussion suggests and emphasizes the importance of improving the lifestyle and nutritional diet; and further providing spiritual support along with natural thyroid medication.

    Various published guidelines recommending serum thyrotropin (TSH)-first thyroid testing are outlined. The entities called "subclinical hypothyroidism" and "subclinical hyperthyroidism" are defined on the basis of abnormal TSH concentrations and normal values of other biochemical thyroid tests. The controversies about follow-up and treatment of these disorders are discussed. The laboratory experience of Mayo Clinic Rochester in using TSH-first thyroid testing and the subsequent implementation of a thyroid test ordering cascade are presented. Finally, recommendations are given for further optimizing laboratory testing for thyroid disorders.

    2010-09-01

    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.

    Surgery is the gold standard treatment for patients with thyroid cancer or nodules suspicious for cancer. Open conventional approach is the standard surgical approach. However, a visible neck incision could be a concern for most young female patients, especially for patients with a history of healing with keloid or hypertrophic scars. Robotic remote access approaches have evolved into a safe and feasible approach in selected patients, providing a hidden scar with good patient satisfaction. This review will focus on the performance and safety of robotic retroauricular thyroid surgery. PMID:28149806

    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.

    Full Text Available Cornual ectopic gestation is one of the causes of “Maternal near miss” cases. In the modern era of IVF treatments and better imaging techniques, more number of cases of cornual ectopic pregnancies is being diagnosed and treated both by conservative and radical methods. Here, we report a case of a recurrent cornual ectopic pregnancy in the early second trimester, which was managed by hysterectomy due to uncontrolled haemorrhage. Thirty five year old Mrs. S, Gravida 4, para2, with one previous ectopic pregnancy presented to the obstetric casualty with acute abdominal pain at 15 weeks +2 days of gestation. On vaginal examination, there was right fornicial fullness and both the fornices were tender. Cervical motion tenderness was also present. On review of her previous records, dating scan done at 8 to 9 weeks showed normal intrauterine pregnancy. An emergency scan was carried out which revealed an empty uterine cavity with gestational sac measuring 3.6×4.4×4.6 cms seen outside the uterus just above the fundus with absent cardiac activity. There was evidence of haemoperitoneum, therefore she was diagnosed with recurrent ruptured ectopic pregnancy.

    Presentation of hydatidiform mole as tubal ectopic pregnancy is very rare. These patients usually present with ectopic pregnancy and are later diagnosed with hydatidiform mole on the basis of histological examination following surgery. We present the case of a 32-year-old female who presented with abdominal pain and vaginal bleed since 2 days of presentation. She was vitally stable. There was mild tenderness in hypogastrium and left iliac fossa. Pelvic examination showed mild bleeding per vaginum and fullness in both fornices. The patient was suspected of having an ectopic pregnancy. Ultrasonography of pelvis revealed fluid in cul-de-sac and a sac like mass of 1.8 cm attached to the left ovary. On laparotomy, there was a left sided tubal ectopic pregnancy and subsequently left salpingectomy was done. Histopathology of the tissue sample showed features of partial hydatidiform mole. Ectopic pregnancy can present as hydatidiform mole in rare cases for which histological examination of the tissue is required to establish the diagnosis.

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

    2016-04-01

    Pregnancy outcomes after emergency contraceptive use has been debated over time, but review of the literature includes mechanisms by which these medications may increase the chance of an ectopic pregnancy. Such cases are infrequently reported, and many emergency providers may not readily consider this possibility when treating patients. This is a case presentation of ectopic pregnancy in a patient who had recently used Plan B (levonorgestrel) emergency contraceptive. She presented with abdominal pain and vaginal spotting, and was evaluated by serum testing and pelvic ultrasound. She was discovered to have a right adnexal pregnancy. She was treated initially with methotrexate, though she ultimately required surgery for definitive treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report aims to bring a unique clinical case to the attention of emergency providers. The goal is to review research on the topic of levonorgestrel use and the incidence of ectopic pregnancies. The mechanism of action of this emergency contraceptive is addressed, and though no definite causal relationship is known between levonorgestrel and ectopic pregnancies, there is a pharmacologic explanation for how this event may occur after use of this medication. Ultimately, the emergency provider will be reminded of the importance of educating the patient on the possible outcomes after its use, including failure of an emergency contraceptive and the potential of ectopic pregnancy.

    Full Text Available Background: Tubal sterilization is the permanent and effective contraception method. This can be performed at any time, but at least half are performed in conjunction with cesarean or vaginal delivery and are termed puerperal. The most complication after tubal ligation is ectopic pregnancy. Ectopic pregnancy is the leading cause of maternal death in first trimester.Case presentation: We present a 33 years old woman gravida5, para4, all normal vaginal delivery, presented with complaints of delayed menstrual period, pelvic pain and spotting. She underwent tubal ligation for two times. For the first time she had puerperal Pomeroy tubal sterilization after third child delivery. Intra uterine pregnancy occurred three years later. One day after vaginal delivery of fourth child, she underwent post partum tubal ligation with the Parkland method. Tubal pregnancy occurred nine months later. Physical examination identified acute abdomen. Pelvic ultrasound showed no gestational sac in uterine cavity. The sac with fetal pole was in right adnexa. Beta-HCG was 2840mIU/ml. She underwent laparotomy. Surgical management included salpingectomy with cornual resection in both sides. The surgery identified Ectopic pregnancy.Conclusion: Any symptoms of pregnancy in a woman after tubal ligation must be investigated; an ectopic pregnancy should be excluded. Ectopic pregnancy must be considered, in any woman with lower abdominal pain, missed period and vaginal bleed-ing. Conception after tubal sterilization can be explained by fistula formation and re-canalization of fallopian tube.

    Full Text Available A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid peroxidase antibody and thyroglobulin antibody serum levels were elevated and T4-free level was normal. Thyroid and total body 99mTc isonitrile scintiscan showed a topic thyroid without radionuclide uptake in the nodule. Fine-needle aspiration of the nodule showed epithelial cells with nuclear atypia and oncocytic changes plus intense lymphoid infiltration and germinative center formation, simulating lymph node metastasis of papillary thyroid carcinoma. Conventional biopsy revealed a parasitic thyroid nodule with Hashimoto's chronic thyroiditis. Parasitic thyroid nodule must always be remembered so that unnecessary surgical assessment and undesirable sequels may be avoided.

    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).

    An ectopic pregnancy is the implantation and development of the ovum fertilized outside the endometrial cavity. Its incidence has increased in the last 30 years, and although its morbimortality has decreased, it is still the first cause of mortality in the first trimester of the pregnancy. Early suspicion is important, particularly in women of fertile age and with risk factors indicative of an extrauterine gestation. The symptomatology is usually amenorrhea, abdominal pain, metrorrhagia, general pregnancy symptoms, and even syncope and shock. The diagnosis of ectopic pregnancy is based on the clinical information, analytical results on mother blood and urine, ultrasound examination, transvaginal culdocentesis, laparoscopic or laparotomic inspection, and a histological study. The treatment can be surgical (salpingostomy or salpingectomy), medical (methotrexate) or expectant, depending on the factors of the ectopic pregnancy: early diagnosis, presence of acute complications, clinical condition of the patient, etc.

    Cushing syndrome due to endogenous hypercortisolism may cause significant morbidity and mortality. The source of excess cortisol may be adrenal, pituitary, or ectopic. Ectopic Cushing syndrome is sometimes difficult to localize on conventional imaging like CT and MRI. After performing a multilevel thoracoabdominal imaging with CT, the evidence regarding the use of radiotracers for PET imaging is unclear due to significant molecular and etiological heterogeneity of potential causes of ectopic Cushing's syndrome. In our systematic review of literature, it appears that GalLium-based (Ga68) somatostatin receptor analogs have better sensitivity in diagnosis of bronchial carcinoids causing Cushing syndrome and FDG PET appears superior for small-cell lung cancers and other aggressive tumors. Further large-scale studies are needed to identify the best PET tracer for this condition.

    Full Text Available Supernumerary breast or polymastia is a well-documented anomaly of the breast and commonly presents along the embryonic milk line extending between the axilla and groin. Reported incidence of accessory breast is 0.4-6% in females. During 2 years period, we encountered only two cases out of twenty cases of axillary lumps. We present one case of fibroadenoma in ectopic breast tissue (EBT in axilla. Ectopic breast denotes breast tissue at more than two pectoral regions, which is mostly benign but at times can be malignant. EBT is at a greater risk of malignancy. Fibroadenoma of ectopic axillary breast tissue (EBT is quiet rare, but should always be kept in mind for differential diagnosis of an axillary mass.

    Gene expression profiling of ovarian carcinoma tissues has shown an increase of four-fold expression of SORT1 gene. Sortilin 1 (NTR-3) is a 95-100 kDa protein normally expressed in heart, brain, placenta, skeletal muscle, spinal cord, thyroid, and testis. However, its expression has never been reported in normal ovary. Here, we report expression of sortilin 1 in ovarian carcinoma tissues both at gene and protein levels. Sortilin 1 was expressed in all ovarian carcinoma patients (n=15) as well as ovarian carcinoma cell lines (n=5) regardless of their phenotypic characteristics. Non-malignant ovaries (n=6) did not express sortilin 1. The molecular basis for this ectopic expression is not yet clear. Our results showed a major cell surface expression of sortilin 1 rather than ER-Golgi compartment where it is mainly expressed. This finding may introduce sortilin 1 as a novel tumor marker for diagnosis of ovarian carcinoma and may signify its therapeutic value in targeted therapy.

    Myocardial and vascular endothelial tissues have receptors for thyroid hormones and are sensitive to changes in the concentrations of circulating thyroid hormones. The importance of thyroid hormones in maintaining cardiovascular homeostasis can be deduced from clinical and experimental data showing that even subtle changes in thyroid hormone concentrations - such as those observed in subclinical hypothyroidism or hyperthyroidism, and low triiodothyronine syndrome - adversely influence the cardiovascular system. Some potential mechanisms linking the two conditions are dyslipidaemia, endothelial dysfunction, blood pressure changes, and direct effects of thyroid hormones on the myocardium. Several interventional trials showed that treatment of subclinical thyroid diseases improves cardiovascular risk factors, which implies potential benefits for reducing cardiovascular events. Over the past 2 decades, accumulating evidence supports the association between abnormal thyroid function at the time of an acute myocardial infarction (MI) and subsequent adverse cardiovascular outcomes. Furthermore, experimental studies showed that thyroid hormones can have an important therapeutic role in reducing infarct size and improving myocardial function after acute MI. In this Review, we summarize the literature on thyroid function in cardiovascular diseases, both as a risk factor as well as in the setting of cardiovascular diseases such as heart failure or acute MI, and outline the effect of thyroid hormone replacement therapy for reducing the risk of cardiovascular disease.

  10. Thyroid hormone and the heart.

    Science.gov (United States)

    Moolman, J A

    2002-01-01

    Thyroid hormone has important cardiovascular effects, and abnormalities of its production cause cardiovascular morbidity. The role of both excessive and insufficient thyroid hormone production in the pathogenesis of clinical cardiac diseases can be deduced from thyroid hormone-induced molecular changes. Thyroid hormone regulates the expression of myocardial genes regulating the handling of calcium, which affects both systolic and diastolic myocardial function. Thyroid hormone also has indirect and direct effects on peripheral vascular smooth muscle tone, and alters the coupling of the left ventricle and arterial system. Excessive production of thyroid hormone results in an increased cardiac output as well as increased cardiac work efficiency, but reduced cardiac reserve. Amiodarone therapy for cardiac rhythm can cause both hyper- and hypothyroidism. Amiodarone-induced thyrotoxicosis (AIT) can be due to either excessive thyroid hormone production (type I AIT) or thyroid hormone release due to an inflammatory condition (type II AIT). Classification of AIT is helpful in guiding therapy. Amiodarone causes changes in the thyroid function tests of euthyroid patients on therapy--it inhibits the conversion of T(4) and T(3), which results in decreased T(3) and slightly increased T(4) serum levels in euthyroid patients. Baseline thyroid functions should therefore be determined before starting amiodarone therapy, and at 6-monthly intervals thereafter.

  11. Etiopathogenesis of Differentiated Thyroid Carcinomas

    2016-08-01

    Full Text Available INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas. We have read, analysed and compare available reviews and original articles investigating different etiological factors in the development of thyroid carcinomas through Google Scholar and PubMed Database. DISCUSSION: Aetiology involved in the development of thyroid carcinomas is multifactorial and includes external influences, as well as constitutional predispositions and genetic etiological factors. The actual effect of environmental and constitutional factors is on promoting genetic and epigenetic alterations which result in cell proliferation and oncogenesis. Until now are identified numerous genetic alterations, assumed to have an important role in oncogenesis, with MAPK and PI3K-AKT as crucial signalling networks regulating growth, proliferation, differentiation and cell survival/apoptosis. CONCLUSION: This new molecular insight could have a crucial impact on diagnosis and also on improving and selecting an appropriate treatment to the patients with thyroid malignancies.

  12. Ectopic Centromere Nucleation by CENP-A in Fission Yeast

    The centromere is a specific chromosomal locus that organizes the assembly of the kinetochore. It plays a fundamental role in accurate chromosome segregation. In most eukaryotic organisms, each chromosome contains a single centromere the position and function of which are epigenetically specified. Occasionally, centromeres form at ectopic loci, which can be detrimental to the cell. However, the mechanisms that protect the cell against ectopic centromeres (neocentromeres) remain poorly understood. Centromere protein-A (CENP-A), a centromere-specific histone 3 (H3) variant, is found in all centromeres and is indispensable for centromere function. Here we report that the overexpression of CENP-ACnp1 in fission yeast results in the assembly of CENP-ACnp1 at noncentromeric chromatin during mitosis and meiosis. The noncentromeric CENP-A preferentially assembles near heterochromatin and is capable of recruiting kinetochore components. Consistent with this, cells overexpressing CENP-ACnp1 exhibit severe chromosome missegregation and spindle microtubule disorganization. In addition, pulse induction of CENP-ACnp1 overexpression reveals that ectopic CENP-A chromatin can persist for multiple generations. Intriguingly, ectopic assembly of CENP-Acnp1 is suppressed by overexpression of histone H3 or H4. Finally, we demonstrate that deletion of the N-terminal domain of CENP-Acnp1 results in an increase in the number of ectopic CENP-A sites and provide evidence that the N-terminal domain of CENP-A prevents CENP-A assembly at ectopic loci via the ubiquitin-dependent proteolysis. These studies expand our current understanding of how noncentromeric chromatin is protected from mistakenly assembling CENP-A. PMID:25298518

    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.

    Hormonal contraceptive pills containing 750 microgram levonorgestrel are the most commonly used postcoital contraceptive method because of their high efficacy and fewer side effects. Emergency contraceptive pills containing levonorgestrel present their effects by several mechanisms, including delayed tubal transport of the ovum. A delay of tubal transportation of an ovum is also one of the possible etiologic factors of tubal ectopic pregnancies. There are limited data on the risk of ectopic pregnancy following levonorgestrel treatment as an emergency contraception. Here, a case of tubal pregnancy associated with the use of levonorgestrel containing emergency contraceptive pills has been presented along with discussion of the relevant literature. PMID:24591928

    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.

    Ectopic lymphoid follicle infiltration is a key event in Hashimoto thyroiditis (HT). Positive regulatory domain zinc finger protein 1 (PRDM1), which is induced by antigen stimulation, can regulate all lymphocyte lineages. Several groups independently demonstrated that human parvovirus B19 (PVB19) is closely associated with HT. Hence, we determined whether PRDM1 is expressed in HT thyroid tissue and whether there is any correlation between PRDM1 expression and PVB19 in the pathogenesis of HT. We detected PRDM1 expression in HT (n = 86), normal thyroid tissue (n = 30), and nontoxic nodular goiter (n = 20) samples using immunohistochemistry. We also detected PVB19 protein in HT samples in a double-blind manner and analyzed the correlation between the 2 proteins using immunofluorescence confocal detection and coimmunoprecipitation. Furthermore, we detected changes of the expression levels of PRDM1 and PVB19 in transfected primary thyroid follicular epithelial cells using real-time quantitative polymerase chain reaction. We found that PRDM1 protein is significantly highly expressed in the injured follicular epithelial cells in HT (83/86 cases) than in normal thyroid cells (0/30 cases) or in nontoxic nodular goiter cells (0/20 cases) (P thyroid epithelial cells also showed PRDM1 up-regulation after PVB19 NS1 transfection. Our findings suggest a previously unrecognized role of PRDM1 and PVB19 in the pathogenesis of HT.

    Spindle epithelial tumor with thymus-like differentiation (SETTLE) of the thyroid gland is a very rare tumor. It is believed to originate from ectopic thymus tissue within the thyroid gland or from branchial pouch remnants that differentiate along the thymic line. A few reports of SETTLE have been presented, but to the best of our knowledge, there is no case report in which detailed preoperative imaging features of SETTLE have been described. In addition, there are no case reports of SETTLE in Korean patients. Thus, we report a case of SETTLE with detailed preoperative ultrasonography and computed tomography features, cytological findings and histopathological results.

    Ectopic canine teeth develop displaced from their normal position. Any permanent tooth can be ectopic, and the cause may be both genetic and environmental. Orthodontic treatment is justified because ectopic canine teeth can migrate in the jaw bone and may damage the adjacent teeth roots and bone. Orthodontic treatment is also justifiable for aesthetic reasons. Diagnosis and treatment of ectopically erupting permanent maxillary canines requires timely management by the orthodontist.

    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 Abstract Viral infections are frequently cited as a major environmental factor involved in subacute thyroiditis and autoimmune thyroid diseases This review examines the data related to the role of viruses in the development of thyroiditis. Our research has been focused on human data. We have reviewed virological data for each type of thyroiditis at different levels of evidence; epidemiological data, serological data or research on circulating viruses, direct evidence of thyroid tissue infection. Interpretation of epidemiological and serological data must be cautious as they don't prove that this pathogen is responsible for the disease. However, direct evidence of the presence of viruses or their components in the organ are available for retroviruses (HFV and mumps in subacute thyroiditis, for retroviruses (HTLV-1, HFV, HIV and SV40 in Graves's disease and for HTLV-1, enterovirus, rubella, mumps virus, HSV, EBV and parvovirus in Hashimoto's thyroiditis. However, it remains to determine whether they are responsible for thyroid diseases or whether they are just innocent bystanders. Further studies are needed to clarify the relationship between viruses and thyroid diseases, in order to develop new strategies for prevention and/or treatment.

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...

    Thyroid scintigraphy is performed in cats and dogs and has been used to a limited degree in other species such as the horse. Thyroid scintigraphy is most commonly used to aid in the diagnosis and treatment management of feline hyperthyroidism but is also used in the evaluation of canine hypothyroidism and canine thyroid carcinoma. This article reviews the normal scintigraphic appearance of the thyroid in the cat, the dog, and the horse and the principles of interpretation of abnormal scan results in the cat and the dog. Radioiodine is the treatment of choice for feline hyperthyroidism, and the principles of its use in the cat are reviewed.

    Full Text Available Objective  To discuss the relative and independent risk factors in ectopic pregnancy. Methods  The clinical data of 870 patients with ectopic pregnancy, admitted from 2005 to 2012, were retrospectively analyzed, with 800 cases of normal pregnancy serving as control. Monofactorial correlation analysis was used to analyze the related risk factor, and logistic regression analysis was used to analyze the independent risk factor. Results  Pelvic adhesion, previous operation, cesarean section delivery, number of pregnancy, artificial abortion, medical abortion, in vitrofertilization and embryo replacement (IVF-ER, and placement of intrauterine device (IUD are the risk factors of ectopic pregnancy, pelvic adhesion, artificial abortion, operation, number of pregnancies and IUD are the independent risk factors, and pelvic adhesion is the major risk factor. Conclusion  Avoidance of unexpected pregnancy as possible, reduction of the number of artificial abortion, prevention and treatment of genital duct inflammation, and standardization of pelvic operation may reduce the incidence of ectopic pregnancy.

    Full Text Available Ectopic pancreas is frequently found in the gastrointestinal tract. Lesions comprise well-developed and normally organized pancreatic tissue outside the pancreas, without anatomic or vascular connections with the true pancreas. Most patients with ectopic pancreas are asymptomatic or exhibit nonspecific symptoms. A 68-year-old Japanese woman had been experiencing intermittent pain in the right upper abdomen. Suddenly, the abdominal pain changed to intense pain in the right flank of the abdomen 2 days later. On initial medical examination, the abdomen exhibited rebound tenderness and distension. The results of laboratory tests revealed increased inflammatory reaction. Abdominal computed tomography showed free air and ascites on the surface of the liver and elevated levels of adipose tissue around the antrum and pylorus of the stomach. Perforation of the upper gastrointestinal tract was diagnosed and we performed urgent surgery. The site of perforation, whose size was 25 mm, was the lesser curvature of the antrum of the stomach. Since it was not possible to perform omentopexy, we performed extensive gastric resection. The reconstruction was a Billroth II operation. Microscopic analysis revealed pancreatic tissue within the ulceration, showing islets of Langerhans, acini, and ducts; the lesion was diagnosed as type I using Heinrich’s criteria. The postoperative course was uneventful. The patient was discharged on day 13 and remains clinically healthy. Gastric perforation due to ectopic pancreas has been reported in 2 cases, including our patient, and is extremely rare. Once gastric perforation has been diagnosed, the presence of ectopic pancreas might be considered.

    When a DNA fragment containing a marker gene was ligated to random chromosomal fragments of Streptococcus pneumoniae and used to transform a recipient strain lacking that gene, the gene was integrated at various locations in the chromosome. Such ectopic integration was demonstrated for the malM gene, and its molecular basis was analyzed with defined donor molecules consisting of ligated fragments containing the malM and sul genes of S. pneumoniae. In a recipient strain deleted in the mal region of its chromosome, these constructs gave Mal/sup +/ transformants in which the malM and sul genes were now linked, with malM located between duplicate sul segments. Ectopic integration was unstable under nonselective conditions; mal(sul) ectopic insertions were lost at a rate of 0.05% per generation. Several possible mechanisms of ectopic integration were examined. The donor molecule is most likely to be a circular form of ligated homologous and nonhomologous fragments that, after entry into the cell, undergoes circular synapsis with the recipient chromosome at the site of homology, followed by repair and additive integration.

    Endometriosis (ENDO) is a disorder in which vascularized growths of endometrial tissue occur outside the uterus. Its symptoms include reduced fertility and severe pelvic pain. Mechanisms that maintain the ectopic growths and evoke symptoms are poorly understood. One factor not yet considered is that the ectopic growths develop their own innervation. Here, we tested the hypothesis that the growths develop both an autonomic and a sensory innervation. We used a rat model of surgically induced ENDO whose growths mimic those in women. Furthermore, similar to women with ENDO, such rats exhibit reduced fertility and increased pelvic nociception. The ENDO was induced by autotransplanting, on mesenteric cascade arteries, small pieces of uterus that formed vascularized cysts. The cysts and healthy uterus were harvested from proestrous rats and immunostained using the pan-neuronal marker PGP9.5 and specific markers for calcitonin gene-related peptide (CGRP) (sensory C and A delta fibers), substance P (SP) (sensory C and A delta fibers) and vesicular monoamine transporter (sympathetic fibers). Cysts (like the uterus) were robustly innervated, with many PGP9.5-stained neurites accompanying blood vessels and extending into nearby luminal epithelial layers. CGRP-, SP-, and vesicular monoamine transporter-immunostained neurites also were observed, with CGRP and SP neurites extending the furthest into the cyst lining. These results demonstrate that ectopic endometrial growths develop an autonomic and sensory innervation. This innervation could contribute not only to symptoms associated with ENDO but also to maintenance of the ectopic growths.

    Ectopic pregnancies account for 1.5% to 2% of all pregnancy in the United States. Of these, approximately 10% implant in nontubal locations, including the abdominal cavity, cervix, ovary, interstitial portion of the fallopian tube, broad ligament, the uterine cornua, or within a cesarean section scar. Because these pregnancies tend to present later than typical tubal pregnancies, they have been associated with greater maternal morbidity and mortality. Advances in ultrasound technology have allowed for earlier diagnosis of nontubal ectopic pregnancies, which in turn has led to the development of novel minimally invasive techniques to manage them. One of these methods involves the local injection of 1 of several agents directly into the ectopic pregnancy. In this article we provide a guide to this technique of local injection, including an overview of the potential agents that can be used, and review the diagnostic and specific ultrasound criteria, other possible treatment options, and overall outcomes for nontubal ectopic pregnancies.

    Parathyroid adenoma detection with dual-phase 99mTc-sestamibi (MIBI) scintigraphy depends on differential MIBI washout from thyroid. However, autoimmune thyroid disease (AITD) may cause MIBI to be retained in the thyroid gland and reduce parathyroid detection. We evaluated the impact of AITD on MIBI thyroid retention and additional benefit of SPECT/CT in these patients. Dual phase planar MIBI and SPECT/CT was performed on 82 patients. SPECT/CT was performed immediately after delayed planar scan. Thyroid density (Hounsfield unit, CT-HU) and size were measured on CT component of SPECT/CT. MIBI uptake in early scans and retention in delayed scans were visually graded and correlated with clinical factors and CT findings. Finally, planar and SPECT/CT findings were compared for parathyroid lesion visualization according to thyroid MIBI retention. In early scan, multivariate analysis showed only thyroid size predicted early uptake. In delayed scan, multivariate analysis showed higher visual grade in early scan, lower CT-HU or AITD were significant predictors for delayed thyroid parenchymal retention. Overall, ten more parathyroid lesions were visualized on SPECT/CT compared to planar scans (57 vs. 47, p = 0.002). SPECT/CT was especially more useful in patients with thyroidal MIBI retention, as eight out of the ten additional lesions detected were found in patients with thyroid MIBI retention. AITD is an important factor for MIBI thyroid parenchymal retention on delayed scans, and may impede parathyroid lesion detection. Patients with MIBI retention in the thyroid parenchyma on delayed scans are likely to benefit from an additional SPECT/CT.

    Serum total and free thyroid hormone concentrations were estimated in 42 patients with epilepsy taking anticonvulsants (phenytoin, phenobarbitone, and carbamazepine either singly or in combination). There was a significant reduction in total thyroxine (TT4), free thyroxine (FT4), and free triiodothyronine (FT3) in the treated group compared with controls. Free hormone concentrations were lower than total hormone concentrations, suggesting that increased clearance of thyroid hormones occurs in patients receiving anticonvulsants. Detailed analysis indicated that phenytoin had a significant depressant effect on TT4, FT4, FT3, and reverse T3 (rT3). Phenobarbitone and carbamazepine had no significant main effects, but there were significant interactions between phenytoin and carbamazepine for TT4 and FT4. phenobarbitone and carbamazepine for FT3, and phenytoin and phenobarbitone for rT3.

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected. Therefore, it is important carefully examine patients with Hashimoto's thyroiditis

  20. Pediatric Medullary Thyroid Carcinoma.

    Science.gov (United States)

    Starenki, Dmytro; Park, Jong-In

    Medullary thyroid carcinoma (MTC), which originates from thyroid parafollicular C cells, accounts for 3 to 5% of thyroid malignancies. MTC occurs either sporadically or in an inherited autosomal dominant manner. Hereditary MTC occurs as a familial MTC or as a part of multiple endocrine neoplasia (MEN) type 2A and B syndromes. A strong genotype-phenotype correlation has been observed between hereditary MTC and germ-line "gain of function" mutations of the RET proto-oncogene. Most cases of pediatric MTC are hereditary whereas sporadic MTC is rare in children and is usually diagnosed in adults. Therefore, MTC in children is most often diagnosed in the course of a familial genetic investigation. The standard treatment of MTC mainly requires surgery involving total thyroidectomy and central neck node dissection before extrathyroidal extension occurs. To prevent MTC development in hereditary syndromes, prophylactic thyroidectomy is performed in presymptomatic patients. An appropriate age at which the surgery should take place is determined based upon the data from genotyping, serum calcitonin measurements, and ultrasonography. For the treatment of advanced MTC cases, the broad spectrum receptor tyrosine kinase inhibitors vandetanib and cabozantinib, which also inhibit RET, are used although they are not always effective.

    Full Text Available Thyroid disorders are common in pregnancy and the most common disorder is subclinical hypothyroidism. Due to the complex hormonal changes during pregnancy, it is important to remember that thyroxine requirements are higher in pregnancy. According to recent American Thyroid Association (ATA guidelines, the recommended reference ranges for TSH are 0.1 to 2.5 mIU/L in the first trimester, 0.2 to 3.0 mIU/L in the second trimester, and 0.3 to 3.0 mIU/L in the third trimester. Maternal hypothyroidism is an easily treatable condition that has been associated with increased risk of low birth weight, fetal distress, and impaired neuropsychological development. Hyperthyroidism in pregnancy is less common as conception is a problem. Majority of them are due to Graves′ disease, though gestational hyperthyroidism is to be excluded. Preferred drug is propylthiouracil (PTU with the target to maintain free T4 in upper normal range. Doses can be reduced in third trimester due to the immune-suppressant effects of pregnancy. Early and effective treatment of thyroid disorder ensures a safe pregnancy with minimal maternal and neonatal complications.

    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.

    Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that approximately 10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5-10%). Differentiated thyroid carcinoma accounts for 90% of all thyroid malignant neoplasias. Although most patients with cancer have a favorable outcome, some individuals present an aggressive form of the disease and poor prognostic despite recent advances in diagnosis and treatment. Here, a set of clinical guidelines for the evaluation and management of patients with thyroid nodules or differentiated thyroid cancer was developed through consensus by 8 member of the Department of Thyroid, Sociedade Brasileira de Endocrinologia e Metabologia. The participants are from different reference medical centers within Brazil, to reflect different practice patterns. Each committee participant was initially assigned to write a section of the document and to submit it to the chairperson, who revised and assembled the sections into a complete draft document, which was then circulated among all committee members for further revision. All committee members further revised and refined the document. The guidelines were developed based on the expert opinion of the committee participants, as well as on previously published information.

    Hashimoto's thyroiditis emerges in patients who have genetic preponderance such as SNPs of CTLA-4 and risk factors such as excess intake of iodine, pregnancy or postpartum period, and smoking. Such risk factors also affect the entire clinical course. One of the major outcomes in Hashimoto's thyroiditis appears to be increased in cardio-vascular risks through subclinical hypothyroidism and concomitant metabolic syndrome, but in most cases, treatment with L-T4 has little effects on cardio-vascular benefit or quality of life. The pregnant women also have risks for obstetric complications and postpartum thyroid dysfunction. The women who have anti-TPO antibodies, type 1 diabetes, or previous history of post-partum thyroid dysfunction are recommended to be measured their TSH. It is noteworthy that Hashimoto's thyroiditis is sometimes complicated with encephalopathy, papillary carcinoma, or IgG4-related thyroiditis. IgG4-related thyroiditis is partly similar but partly discerned from a variant of Hashimoto's thyroiditis. The pathogenetic roles of this variant on autoimmune-based thyroiditis remain unclear.

    Thyroid cancer is the most common endocrine cancer with 1,690 deaths each year. There are four main types of which the papillary and follicular types together account for >90% followed by medullary cancers with 3% to 5% and anaplastic carcinomas making up <3%. Epigenetic events of DNA hypermethylation are emerging as promising molecular targets for cancer detection. Our immediate and long term goal is to identify DNA methylation markers for early detection of thyroid cancer. This pilot study comprised of 21 patients to include 11 papillary thyroid cancers (PTC), 2 follicular thyroid cancers (FTC), 5 normal thyroid cases, and 3 hyperthyroid cases. Aberrant promoter methylation was examined in 24 tumor suppressor genes using the methylation specific multiplex ligation-dependent probe amplification (MS-MLPA) assay and in the NIS gene using methylation-specific PCR (MSP). The frequently methylated genes were CASP8 (17/21), RASSF1 (16/21) and NIS (9/21). In the normal samples, CASP8, RASSF1 and NIS were methylated in 5/5, 4/5 and 1/5 respectively. In the hyperthyroid samples, CASP8, RASSF1 and NIS were methylated in 3/3, 2/3 and 1/3 respectively. In the thyroid cancers, CASP8, RASSF1, and NIS were methylated in 9/13, 10/13, and 7/13 respectively. CASP8, RASSF1 and NIS were also methylated in concurrently present normal thyroid tissue in 3/11, 4/11 and 3/11 matched thyroid cancer cases (matched for presence of both normal thyroid tissue and thyroid cancer), respectively. Our data suggests that aberrant methylation of CASP8, RASSF1, and NIS maybe an early change in thyroid tumorigenesis regardless of cell type.

    Hashimoto thyroiditis (HT) is an autoimmune thyroid disorder that usually presents as a diffuse, nontender goiter, whereas subacute thyroiditis (SAT) is an uncommon disease that is characterized by tender thyroid enlargement, transient thyrotoxicosis, and an elevated erythrocyte sedimentation rate (ESR). Very rarely, patients with HT can present with painful, tender goiter or fever, a mimic of SAT. We report a case of painful HT in a 68-year-old woman who presented with pain and tenderness in a chronic goiter. Her ESR was definitely elevated and her thyroid laboratory tests suggested subclinical hypothyroidism of autoimmune origin. (99m)Tc pertechnetate uptake was markedly decreased. Fine needle aspiration biopsy revealed reactive and polymorphous lymphoid cells and occasional epithelial cells with Hürthle cell changes. Her clinical symptoms showed a dramatic response to glucocorticoid treatment. She became hypothyroid finally and is now on levothyroxine therapy.

    Thyroid hormones play a critical role in the metabolic activity of the adult brain, and neuropsychiatric manifestations of thyroid disease have long been recognised. However, it is only recently that methodology such as functional neuroimaging has been available to facilitate investigation of thyroid hormone metabolism. Although the role of thyroid hormones in the adult brain is not yet specified, it is clear that without optimal thyroid function, mood disturbance, cognitive impairment and other psychiatric symptoms can emerge. Additionally, laboratory measurements of peripheral thyroid function may not adequately characterise central thyroid metabolism. Here, we review the relationship between thyroid hormone and neuropsychiatric symptoms in patients with primary thyroid disease and primary mood disorders.

    Full Text Available Notch signalling plays an important role in endocrine development, through its target gene Hes1. Hes1, a bHLH transcriptional repressor, influences progenitor cell proliferation and differentiation. Recently, Hes1 was shown to be expressed in the thyroid and regulate expression of the sodium iodide symporter (Nis. To investigate the role of Hes1 for thyroid development, we studied thyroid morphology and function in mice lacking Hes1. During normal mouse thyroid development, Hes1 was detected from E9.5 onwards in the median anlage, and at E11.5 in the ultimobranchial bodies. Hes1(-/- mouse embryos had a significantly lower number of Nkx2-1-positive progenitor cells (p<0.05 at E9.5 and at E11.5. Moreover, Hes1(-/- mouse embryos showed a significantly smaller total thyroid surface area (-40 to -60% compared to wild type mice at all study time points (E9.5-E16.5. In both Hes1(-/- and wild type mouse embryos, most Nkx2-1-positive thyroid cells expressed the cell cycle inhibitor p57 at E9.5 in correlation with low proliferation index. In Hes1(-/- mouse embryos, fusion of the median anlage with the ultimobranchial bodies was delayed by 3 days (E16.5 vs. E13.5 in wild type mice. After fusion of thyroid anlages, hypoplastic Hes1(-/- thyroids revealed a significantly decreased labelling area for T4 (-78% and calcitonin (-65% normalized to Nkx2-1 positive cells. Decreased T4-synthesis might be due to reduced Nis labelling area (-69%. These findings suggest a dual role of Hes1 during thyroid development: first, control of the number of both thyrocyte and C-cell progenitors, via a p57-independent mechanism; second, adequate differentiation and endocrine function of thyrocytes and C-cells.

    Radioiodine (RI) such as (131)I or (124)I, can generate luminescent emission and be detected with an optical imaging (OI) device. To evaluate the possibility of a novel Cerenkov luminescence imaging (CLI) for application in thyroid research, we performed feasibility studies of CLI by RI in the thyroid gland and human anaplastic thyroid carcinoma cells expressing sodium iodide symporter gene (ARO-NIS). For in vitro study, FRTL-5 and ARO-NIS were incubated with RI, and the luminometric and CLI intensity was measured with luminometer and OI device. Luminescence intensity was compared with the radioactivity measured with γ-counter. In vivo CLI of the thyroid gland was performed in mice after intravenous injection of RI with and without thyroid blocking. Mice were implanted with ARO-NIS subcutaneously, and CLI was performed with injection of (124)I. Small animal PET or γ-camera imaging was also performed. CLI intensities of thyroid gland and ARO-NIS were quantified, and compared with the radioactivities measured from nuclear images (NI). Luminometric assay and OI confirmed RI uptake in the cells in a dose-dependent manner, and luminescence intensity was well correlated with radioactivity of the cells. CLI clearly demonstrated RI uptake in thyroid gland and xenografted ARO-NIS cells in mice, which was further confirmed by NI. A strong positive correlation was observed between CLI intensity and radioactivity assessed by NI. We successfully demonstrated dual molecular imaging of CLI and NI using RI both in vitro and in vivo. CLI can provide a new OI strategy in preclinical thyroid studies.

    Full Text Available Abstract Introduction Subacute lymphocytic thyroiditis is anautoimmune thyroid disease presenting with transient thyrotoxicosis as well as transient hypothyroidism. Several factors have been thought to be the initiating event in subacute lymphocytic thyroiditis. However, subacute lymphocytic thyroiditis that develops after thyroid lobectomy has not yet been reported in the literature. We report a case of subacute lymphocytic thyroiditis after lobectomy in a patient with papillary thyroid carcinoma. Case presentation A 30-year-old Korean woman was referred to our center for thyroid tumor operation. She was diagnosed with suspicious papillary thyroid carcinoma by fine needle aspiration at a local medical clinic. The thyroid ultrasonography demonstrated a diffusely enlarged thyroid gland with a 0.4×0.3cm sized hypoechoic nodule in the left lobe. Left thyroid lobectomy by endoscopic thyroidectomy was performed via a transaxillary approach, and the nodule was confirmed to be a papillary thyroid carcinoma. On postoperative day 1, a thyroid function test revealed hyperthyroidism, and on postoperative day 8, a thyroid function test again revealed hyperthyroidism with decreased radioactive iodine uptake. Thyroid function tests showed euthyroid on postoperative day 48 and hypothyroidism on postoperative day 86. She was treated with levothyroxine. Conclusion Subacute lymphocytic thyroiditis can develop after thyroid lobectomy. Thyroid autoantigen released during thyroid lobectomy may cause the onset or exacerbation of the destructive process.

    Full Text Available An 18-year-old, male, castrated, captive-born leopard (Panthera pardus presented to Colorado State University’s Veterinary Teaching Hospital with a two-week history of regurgitation. Thoracic radiographs and ultrasound revealed a well-differentiated cranioventral mediastinal mass measuring 7.5 × 10 × 5.5 cm, impinging the esophagus. A sternotomy followed by mass excision was performed. The mass was diagnosed as an ectopic thyroid carcinoma. The leopard recovered from surgery with minimal complications and returned to near-normal activity levels for just under 6 months before rapidly declining. He had an acute onset of severe dyspnea and lethargy and was euthanized. On postmortem examination the tumor was found to involve the lung, liver, thyroid, parietal pleura, bronchial lymph nodes, and the internal intercostal muscles. This case report describes the history, diagnosis, surgical treatment, postoperative care, and recovery as well as the eventual decline, euthanasia, and necropsy of a leopard with thyroid carcinoma. When compared to thyroid carcinomas of domestic animals, the leopard’s disease process more closely resembles the disease process seen in domestic canines compared to domestic cats.

    Full Text Available Thyroid carcinoma showing thymic-like differentiation (CASTLE comprises a rare neoplasm of the thyroid gland which arises from ectopic thymic tissue or remnants of brachial pouches. CASTLE is regarded as an indolent neoplasm with a favorable prognosis, irrespective of its metastatic potential. Diagnosis is difficult as clinicopathological features have not been yet well-defined. Radiological findings are not specific and only immunohistochemical positivity for CD5 and CD117 staining is highly suggestive of CASTLE. Despite lack of universally accepted treatment recommendations, the mainstay treatment includes thyroidectomy and systematic lymph node dissection. We report a case of CASTLE tumour with very uncommon characteristics developed in a 76-year-old man, who presented with rapidly deteriorating dyspnea and severe cough, resulting in respiratory failure. At surgery, a suspicious looking tumour arising from the upper pole of the right lobe of the thyroid gland, surrounding the trachea and displacing the right common carotid artery, was identified. The patient underwent en bloc resection of the tumour with the thyroid gland and regional lymph node dissection. This is the first reported case of CASTLE causing tracheal ring fracture.

    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. {sup 131}I treatment of functional autonomy and hyperthyroidism is considered an effective and safe procedure.

    Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy.

    Full Text Available Ectopic canine teeth develop displaced from their normal position. Any permanent tooth can be ectopic, and the cause may be both genetic and environmental. Orthodontic treatment is justified because ectopic canine teeth can migrate in the jaw bone and may damage the adjacent teeth roots and bone. Orthodontic treatment is also justifiable for aesthetic reasons. Diagnosis and treatment of ectopically erupting permanent maxillary canines requires timely management by the orthodontist. Internal or external root resorption of teeth adjacent to the ectopic canine is the most common sequel. Malocclusion with severe crowding is difficult to treat without extraction. Non-extraction treatment of ectopic canines can compromise the patient′s profile. This article represents two cases of extraction treatment approach for buccally displaced or ectopic canine in a patient with severe crowding in the mandibular arch.
