    After the introduction of minimally invasive operative techniques in the surgery of organs located in body cavities, extensive work has been done in the last five years with respect to their application in thyroid gland surgery as well. In 2011, 406 patients underwent thyroid surgery at the Department of Surgery, Kaspela General Hospital for Active Treatment EOOD - Plovdiv. The study involved 48 of these patients, chosen at random and divided into two groups (A-minimally invasive thyroidectomy (MIT) - 26 patients, and B - minimally invasive video-assisted thyroidectomy (MIVAT) - 22 patients). All patients included in the study were selected on the basis of presence of one or more indeterminate nodules (fine needle aspiration biopsy - FNAB) sized up to 3.5 cm, with normal size of the thyroid gland up to 20-25 cm2, detected by preoperative ultrasonography. The study excluded patients with recurrent goitre, malignant disease of the thyroid gland and evidence of preoperative radiation therapy in the area of the head, neck and/or upper mediastinum. The preoperative investigation included history, physical examination, blood indices, echography, gamma camera and FNAB. Sensation of pain was evaluated by the patients according to a visual analogue scale, where lack of pain was evaluated as 0, and the most severe pain was evaluated as 10. The average duration of the hospitalization of patients undergoing MIT was 16 +/- 3.14 hours, whereas the patients undergoing MIVAT had to stay at the hospital for 18 +/- 3.56 hours. No complications were registered regarding the recurrent laryngeal nerves (RLN), as well as the operative wound. It should be noted that in all patients the course of the respective RLN was identified during the operative intervention, visually in most cases, or by electrostimulation. Postoperative hypoparathyroidism, registered by measuring the level of serum calcium, was observed in one visual analogue scale, as well as in the administration of pain

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

    Full text: The surgery department of Central Hospital no.1 operated on 1690 thyroid disease patients in last 7 years (2000-2007). Patients' ages were 9-80 years. Female : Male ratio 10 : 1. In the last years morbidity is changed, Diffuse toxic Goiter has decreased, Thyroid nodule and cancer has increased. During last 7 years we have operated 164 patients for thyroid mass. 69 cases (51.54%) of them were thyroid carcinoma. In this 69 cases include Anaplastic carcinoma 3, Papillary carcinoma 36, follicular carcinoma 30 cases. 80 percent patients from thyroid cancer cases were diagnosed in pre-operative period, 20 percent were diagnosed in inter and post-operation period. For thyroid cancer cases we made the following operations: - Total thyroidectomy 20 cases, Hemithyroidectomy 30 cases, Hemithyroidectomy 29 cases. After operation 49 patients were sent for radioactive I-131 treatment and 3 cases which recurred, were operated a second time. In the treatment of DTG, there has been a decrease in the number of surgeries, while great increase in the use of I-131. From 1990 to 1999 have been done 1307 operations, because of thyroid disease: - 580 (44.37%) for DTG, 636 (48.66%) for thyroid nodule, 37 ( 2.83%) for thyroid cancer. From 2000 to 2007 we have conducted 1608 operations, because of thyroid disease: 473 (29.41%) for DTG, 919 (57.15%) for thyroid nodule and 134 (8.33%) for thyroid cancer. All operations were done by O.V.Nicolaev's method. (intracapsular resection). Conclusion: 1. the numbers of thyroid cases which have been treated by operation is changing. There are an increasing number of cases of Thyroid nodule and thyroid cancer. 2. There is need to improve preoperative diagnostics. 3. Combination of surgery treatment and radioactive I131 treatment gave good results for thyroid cancer. (author)

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

    2012-02-01

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

  12. Measuring Quality in Thyroid Cancer Surgery

    2014-01-01

    Full Text Available Many of the surgical quality measures currently in use are not disease specific. For thyroid cancer, mortality and even recurrence are difficult to measure since mortality is rare and recurrence can take decades to occur. Therefore, there is a critical need for quality indicators in thyroid cancer surgery that are easily measured and disease specific. Here we will review recent research on two potential quality indicators in thyroid cancer surgery. The uptake percentage on postoperative radioactive iodine scans indicates the completeness of resection. Another measure, the lymph node ratio, is the proportion of metastatic nodes to the total number of nodes dissected. This serves as a more global measure of quality since it indicates not only the completeness of lymph node dissection but also the preoperative lymph node evaluation and decision-making. Together, these two quality measures offer a more accurate, disease-specific oncologic indicator of quality that can help guide quality assurance and improvement.

    To evaluate patient perception of morbidity after thyroid surgery. Survey of consecutive patients (case series). A standardized questionnaire was mailed to 312 patients who underwent thyroid surgery during a 3-year period (January 2008 to December 2010). Replies were received from 202 (64%) patients (56 male, 166 female; age, 55 ± 16 years) at 6 to 39 months (median, 23 months) after lobectomy (n = 119) or total thyroidectomy (n = 76) for benign (n = 160) or malignant (n = 42) conditions. Subjective voice assessment using a visual analogue scale was normal in 111 patients, deteriorated in 80 patients, and improved in 21 patients. Voice handicap index scores were normal in 126 (62%) patients and increased in 76 (38%) patients to a median of 17 (range, 11-29). Voice-related quality of life was excellent in 107 (53%) patients, fair to good in 66 patients, and poor to fair in 29 patients. Subjective assessment of swallowing was reported as normal in 84 patients, moderately affected in 56 patients (score, 11-15) and severely affected in 62 patients (score, 16-40; median, 23). Calcium supplements prescribed routinely after bilateral surgery were interrupted within 2 to 4 weeks in 56 patients and within 3 to 6 months in 18 patients. None of the respondents had persistent hypoparathyroidism. Appearance of the scar assessed using the Manchester score ranged from 5 to 16 (median, 7). Asked whether they would consider robotic thyroid surgery to avoid a cervical scar, only 38 patients said they were definitely interested. A large proportion of patients report persistent moderate voice and swallowing problems after thyroid surgery. These findings are similar to a recent international multicenter survey of more than 2,000 patients with thyroid cancer. Hypocalcemia and cosmetic outcome raised no significant concerns.

    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.

    This is a preliminary analysis of intraoperative neuromonitoring (IONM)-related websites available to the general public with respect to thyroid surgery. Four key terms and/or phrases (neuromonitoring AND thyroid AND neck surgery, intraoperative neuromonitoring, intraoperative electrophysiological monitoring, IONM) were entered separately into the search engines Google.com, Yahoo.com and Bing.com. The first 50 results obtained for each search procedure were evaluated. Websites were evaluated for content quality using the validated DISCERN rating instrument. Readability was graded by the Flesch Reading Ease Score and the Flesch-Kincaid Grade Level. The results were related to scientific publications in most cases (64%). A large percentage (59%) of the servers are located in the USA. The main language used is English (91%); only 19% of the websites are multilingual or in other languages. 58% of the sites were rated as excellent to good and 42% as fair to poor. The median Flesch Reading Ease Score was 49.6; the median Flesch-Kincaid Grade Level was 13.85. World Wide Web information about IONM in thyroid surgery is too specific and difficult and poorly accessible to the general public. Copyright © 2013 Elsevier Ltd and Surgical Associates Ltd.

    Iatrogenic trauma induced by thyroid surgery is the most common etiology of unilateral vocal fold paralysis (UVFP). UVFP after thyroid surgery may lead to profound physical and psychosocial distress. This study comprehensively evaluated UVFP caused by thyroid surgery, and compared the results with those caused by other surgical trauma. Patients with surgery-related UVFP were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form-36 Health Survey quality-of-life questionnaire. Patients with thyroid surgery and other surgeries were compared. A total of 105 patients were recruited, of whom 52 and 53 were assigned to the thyroid surgery and the other surgery group, respectively. Patients in the thyroid surgery group had a higher proportion of external branch of superior laryngeal nerve (eSLN) involvement, longer duration from disease onset to the first laryngeal electromyography examination, lower jitter, higher harmonic-to-noise ratio, and better quality of life compared with the other surgery group. Specifically for patients in the thyroid surgery group, those with eSLN involvement tended to have more pronounced impairment in jitter and shimmer compared with patients without eSLN involvement. UVFP caused by thyroid surgery has a distinct clinical presentation with relatively high involvement in the eSLN, better voice acoustics, longer waiting time before asking for evaluation, and less impact on quality of life. The involvement of eSLN in these patients further impaired their voice. Early referral is suggested for these patients, especially with suspected eSLN injury.

    To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

    1989-12-01

    Mortality and complication rate of thyroid surgery was evaluated between 1980 and 1987. Patients undergoing thyroidectomy during parathyroidectomy, tracheotomy or tumor operation in the anterior mediastinum were excluded. 548 thyroidectomies were performed in 536 patients. There were no mortalities. The incidence of local complications was 16% with paralysis of the recurrent nerve being the most frequent (6.2%). Other complications were hematoma or hemorrhage (4.9%), hypocalcemia (2.1%), allergic skin reaction (1.3%), or wound infection (0.7%). 2.2% of the patients needed reoperation because of false negative interpretation of a frozen section, or carcinoma in final histology. Systemic complications were found in 13 patients (2%), 6 of whom required intensive care treatment. Statistical analysis revealed that patients undergoing total thyroidectomy or re-thyroidectomy, and patients older than 50 years are at higher risk for local complications.

    Reoperative thyroid surgery is associated with a higher morbidity and has traditionally been done in conventional open approach. This study aimed to evaluate the safety and effectiveness of endoscopic areola approach for reoperative thyroid surgery. A retrospective study was conducted in 46 patients undergoing reoperative thyroid surgery with endoscopic areola approach (endoscopic group) and 70 patients with conventional open approach (open group). Perioperative and follow-up outcomes were compared between the two groups. Baseline characteristics were comparable between the two groups. Except for two cases of the endoscopic group intraoperatively converted to open surgery, all the other surgery was successfully completed. No significant difference was found between two groups concerning operation time, drainage volume, drainage time and postoperative hospital stay (all P > 0.05). Estimated blood loss was more in the open group than the endoscopic group (P = 0.000). Although not statistically significant, the overall complication rate was less in the endoscopic group than in the open group (21.7 vs. 37.1 %, P = 0.079). Of these complications, transient hypocalcemia was the most common (endoscopic group, 17.4 %; open group, 21.4 %; P = 0.594). One patient of the endoscopic group and 7 patients of the open group suffered from transient recurrent laryngeal nerve (RLN) paralysis (P = 0.210). Moreover, 2 patients of open group experienced permanent RLN paralysis. During the follow-up period (range 1-6 years), no recurrent case was encountered, but the endoscopic group had a higher cosmetic score (9.0 ± 0.9 vs. 5.9 ± 0.9, P = 0.000). In high-volume centers, with strict operation indication, sufficient preoperative evaluation and careful surgical maneuvers, endoscopic areola approach is a safe and effective method for reoperative thyroid surgery, allowing to provide a better cosmetic result and reduce intraoperative blood loss compared with open

    A descriptive and prospective study on the practice of ambulatory major surgery to eliminate benign tumours of the thyroid gland, was carried out in the General Surgery Service of 'Dr. Joaquin Castillo Duany' Teaching Clinical Surgical Hospital in Santiago de Cuba during the years 1996-2008, both included, through a previous clinical evaluation of 74 patients in the Endocrinology Outpatient Department, where it was decided that they could definitely have a surgical treatment. The female sex, the age groups from 31 to 45 years, the hemithyroidectomy as surgical technique, acupuncture as analgesic procedure and the follicular adenoma as cytohistological result prevailed in the case material. Mild complications occurred in 5 members of the sample, but recovery was absolute in all, so that even 72 of them were discharged before the 24 hours. Due to its good acceptance, this surgical method is beneficial for patient and hospital institutions.(author)

    The goal of this study was to assess the clinicopathologic and ultrasonographic features of thyroid nodules with nondiagnostic results on repeat ultrasonography (US)-guided fineneedle aspiration biopsy (FNAB) according to size and the number of suspicious findings and to determine the proper management of nodules with consecutive nondiagnostic results. This retrospective study included 297 nodules with nondiagnostic results on repeat FNAB that were evaluated by US over the course of at least 12 months of follow-up, a follow-up biopsy, or an operation. We compared clinical and US variables between benign and malignant nodules in thyroid nodules with repeat nondiagnostic results. The comparison of benign and malignant nodules with repeat nondiagnostic results revealed that age, marked hypoechogenicity, irregular or microlobulated margins, microcalcifications, and nonparallel shape were significantly associated with malignancy. Multivariate logistic regression analysis in malignant nodules revealed that microcalcifications and irregular or microlobulated margins were independently associated with malignancy. Among them, only irregular or microlobulated margins were independently significant as a predictor of malignancy in repeatedly nondiagnostic nodules measuring >10 mm. Using receiver operating characteristic analysis, the best cutoff value for the “number of suspicious findings” between benign and malignant nodules was three in nodules of all sizes, three in nodules measuring ≤10 mm, and two in nodules measuring >10 mm. Irregular or microlobulated margins may be the most frequent US features in repeatedly nondiagnostic nodules >10 mm. The presence of “two or more suspicious findings” can be used as the cutoff for distinguishing benign and malignant nodules.

    The main benefits of robot-assisted transaxillary thyroid surgery are to overcome the technical limitations of other endoscopic procedures for this surgical pathology and to avoid any cervical skin incision. This article describes the first experience of a Romanian team with the endoscopic robot-assisted thyroid surgery. We used the da Vinci SI intuitive surgical system to carry out 50 thyroid operations: 33 unilateral total lobectomies with isthmectomy (TL), 8 unilateral total lobectomies, with contralateral subtotal lobectomy, and 9 total thyroidectomies. Preoperatively, the patients were diagnosed with nodular goiter in 42 cases, nodular autoimmune thyroiditis in 3 cases, Basedow disease in 2 cases, toxic thyroid adenoma in 2 cases, and diffuse goiter in 1 case. We analyzed the clinical characteristics, size and location of the nodules, surgery duration, postoperative complications, pain medication, histopathological findings and postoperative cosmetic results. All surgical procedures were carried out without major incidents. One case required conversion to open approach. The mean length of surgery was 159 ± 38.2 min and the average console time was 68 ± 39.9 min; postoperatively, we recorded one case of transient brachial plexus neurapraxia, one transient vocal cord paresis, one transient hypocalcemia, and four postoperative wound complications. The final histopathological examination revealed two cases of well-differentiated carcinoma. This paper reports the largest series to date in Southeast Europe about robot-assisted transaxillary thyroidectomy. On a group of selected Caucasian patients, postoperative results were similar to open cervicotomy in terms of postoperative complications. The major cosmetic advantage is the absence of scar in the anterior cervical region.

  10. Thyroid Surgery for Elderly Patients: Are They at Increased Operative Risks?

    Full Text Available An increasing elderly population, a rising incidence of differentiated thyroid carcinoma (DTC, and a rising incidence of benign nodular disease with age are all contributing to a rise in thyroid operations for the elderly. Literature review on the outcome and safety of thyroid surgery in elderly patients has been filled with conflicting results and this subject remains controversial. Although most single-institution studies conducted by high-volume surgeons did not find significant differences of complication rates in elderly when compared with younger cohorts, they often lacked the power necessary to identify subtle differences and suffered from various selection and referral biases. Recent evidence from large population-based studies concluded that thyroid surgery in the elderly was associated with higher complication rates. One of the major contributing factors for the increased complication rate was because most elderly patients suffered from many preexisting comorbidities. Therefore, elderly patients who have abnormal thyroid findings should complete a thorough preoperative workup and better postoperative care after undergoing any thyroid surgery. Furthermore, these high-risk patients would benefit if they could be referred to high-volume, specialized surgical units early. In this systemic review, we aimed to evaluate different issues and controversies in thyroidectomy for elderly patients.

Material and Methods: Randomized and controlled trial. This study analyses the incidents of tears in sterile surgical gloves used by surgeons during operations on 3 types of thyroid diseases according to the 10th revision of International Statistical Classification of Diseases and Related Health Problems (ICD-10 codes. Nine hundred seventy-two pairs (sets of gloves were collected from 321 surgical procedures. All gloves were tested immediately following surgery using the water leak test (EN455-1 to detect leakage. Results: Glove perforation was detected in 89 of 972 glove sets (9.2%. Statistically relevant more often glove tears occurred in operator than the 1st assistant (p < 0.001. The sites of perforation were localized mostly on the middle finger of the non-dominant hand (22.5%, and the non-dominant ring finger (17.9%. Conclusions: This study has proved that the role performed by the surgeon during the procedure (operator, 1st assistant has significant influence on the risk of glove perforations. Nearly 90% of glove perforations are unnoticed during surgery.

    Background: The success of surgery for thyroid cancer hinges on thorough and accurate preoperative imaging, which enables complete clearance of the primary tumor and affected lymph node compartments. This working group was charged by the Surgical Affairs Committee of the American Thyroid Association to examine the available literature and to review the most appropriate imaging studies for the planning of initial and revision surgery for thyroid cancer. Summary: Ultrasound remains the most important imaging modality in the evaluation of thyroid cancer, and should be used routinely to assess both the primary tumor and all associated cervical lymph node basins preoperatively. Positive lymph nodes may be distinguished from normal nodes based upon size, shape, echogenicity, hypervascularity, loss of hilar architecture, and the presence of calcifications. Ultrasound-guided fine-needle aspiration of suspicious lymph nodes may be useful in guiding the extent of surgery. Cross-sectional imaging (computed tomography with contrast or magnetic resonance imaging) may be considered in select circumstances to better characterize tumor invasion and bulky, inferiorly located, or posteriorly located lymph nodes, or when ultrasound expertise is not available. The above recommendations are applicable to both initial and revision surgery. Functional imaging with positron emission tomography (PET) or PET-CT may be helpful in cases of recurrent cancer with positive tumor markers and negative anatomic imaging. PMID:25188202

    Owing to close anatomical and embryological connexions between the thyroid, parathyroids and thymus,manifold coexisting pathology can be identified during the surgery of hyperparathyroidism (Hp). In this retrospective study we report the incidence, clinical forms, histology and management of thyroid and thymic synchronous lesions encountered in as eries of 82 consecutive patients with various types of Hp operated on in the last three decades. Demography, clinical records, biochemical data, imaging procedures, pathology reports and surgical protocols were revised. Between 1984-2013, 82 cases of Hp, 20 primary and 62 renal (27 secondary and 35 tertiary), 57 women and 25 males (sex ratio: 2.3 1) of 15-72 (mean 46.5) years, under went surgery in our clinic. Concomitant thyroid exereses were performed in 32 patients (2 subtotal thyroidectomies, 12 lobectomies, 8 atypical resections and 10 diagnosis biopsies), foruni- or bilateral (multi)nodular goiters or different €œminutelesions. Pathology showed 11 colloid goiters, 3 follicular adenomas,5 nodular hyperplasias and 6 thyroiditis cases, 3 papillary microcarcinomas and 4 specimens with normal thyroid tissue.Excision of the fibrofatty retromanubrial tissue in total parathyroidectomies for renal Hp (19 cases) revealed one nonmyastenicthymoma, one thymic cyst and thymic remnants in 6 patients.Morbidity in these extended operations was not significantly increased, comparing to the parathyroid exploration alone. Meticulous pre- and intraoperative evaluation in all cases of Hp enables the actual shift from bilateral neck exploration to minimally invasive surgery,increasing however the potential risk of missing thyroid or thymic coexistent significant lesions. The surgeon dedicated to this pathology must be aware of the possibility of encountering such synchronous association and make generous efforts to wards their complete cure in a single operation.

    Surgical management of thyroid diseases (BTDs) has been a topic of interest and confusion for many years. Almost 80% of thyroidectomies at an average endocrine surgical unit are carried out for BTDs.Resistance to surgical intervention in BTDs has been based on the belief that increased complication rate is inherent in its use, this is despite thepotential advatages in terms of confirming the benign nature of the lesion, controlling the disease, and relieving of local symptoms of large neck mass. Benign thyroid diseases are more likely to occur in middle-aged woman living in iodine deficient areas, or have a family history of goiter, or in patients taking iodine-containig drugs, like amoidarone, or in patients with previous history of x-ray exposure. However, the physician must be carefull in making the diagnosis of BTDsin patients of extremes of age or in presence of positive history of radiation, or in patients with family history of thyroid or colon cancer . In this atricle we will review the etiology,epidemiology , diagonastic methodologiesand the recent trends in the sugical and medical mangement of BTDs. (author)

  18. A STUDY ON COMPLICATIONS OF THYROID SURGERY AT GOVERNMENT GENERAL HOSPITAL KAKINADA

    2017-05-01

    Full Text Available BACKGROUND Thyroid disorders are one of the most common causes of metabolic disturbances with surgery forming the main stay of treatment of thyroid swellings. Thyroid surgery in the hands of experienced surgeons is currently one of the safest procedures performed. While complications following thyroidectomy are rare, their consequences can often be debilitating and even life-threatening when they occur. This prospective study intends to assess the occurrence of various postoperative complications following different thyroidectomy procedures and the role of adequate preoperative patient preparation, careful and meticulous surgical technique and early recognition of postoperative complications with the prompt institution of treatment in reducing morbidity and providing the patient with the best chance of a satisfactory outcome. MATERIALS AND METHODS The present clinical study on complications of thyroid surgery has been made over a period of 24 months from August 2014 to August 2016 at Government General Hospital, Kakinada, utilising the cases admitted and treated in the Department of General Surgery. 441 cases were operated during this span of period (n=441, among them 55 complications were observed. RESULTS Thyroid surgeries constituted 8.3% of major surgical procedures carried out at our institution. Solitary thyroid nodule constituted most common thyroid disorder in this study forming 54% of cases followed by MNG (29%. Most of the cases were prevalent in the age group of third and fourth decade. The youngest patient of this series was 18 years and oldest was 65 years. Airway problems in postoperative period were found in 2.3% cases. Haematoma, recurrent laryngeal nerve injury and tracheal collapse secondary to the tracheomalacia were the contributory factors. In this study, 3 cases had permanent/bilateral RLN injury, tracheostomy was done. Postoperative hypocalcaemia constituted the most common complication in this study. Permanent

    2017-07-01

    Full Text Available Background: Endoscopic-assisted transoral surgery, including transoral robotic surgery for metastatic retropharyngeal lymph node (RPN from well-differentiated thyroid cancer, has been reported to reduce the complications resulting from transcervical and transmandibular approaches. However, the narrow working space and difficulty identifying RPN are problematic. To solve these issues, several studies have used intraoperative ultrasound in endoscopic-assisted transoral surgery. However, the type of ultrasonography suitable for this purpose remains unclear. Case Presentation: A 60-year-old female with thyroid papillary carcinoma (T4aN1bM0 initially underwent total thyroidectomy and paratracheal and selective neck dissections (D2a, with resectional management of recurrent laryngeal nerve, trachea, and esophagus. Three years later, she was diagnosed with left retropharyngeal and upper mediastinal lymph node metastases of papillary thyroid cancer. Transoral videolaryngoscopic surgery was performed with a combination of ultrasonography with a flexible laparoscopic transducer manipulated with forceps for identifying RPN intraoperatively. Due to the transducer’s small size and thin, flexible cable, the transducer interrupted the procedure in spite of the narrowness of oral cavity. RPN was resected completely without adverse events. Conclusion: We performed intraoperative ultrasound-guided endoscopic transoral surgery for metastatic RPN from papillary thyroid cancer and achieved complete resection as well as preservation of swallowing function.

    Full Text Available Aim: The use of local anesthetics for pain management following neck surgery is not a well-studied field. Material and Method: Sixty patients scheduled for thyroid surgery were randomly allocated into two groups. Wound infiltration with 0.25% levobupivacaine was performed before the incision in Group 1 and at the end of surgery in Group 2. Pain scores and side effects were followed for 24 hours. Intraoperative and postoperative analgesic consumption and first analgesic requirement time were recorded for each patient. Patient satisfaction was also evaluated at the end of 24 hours. Results: Lower pain scores, less analgesic consumption, later analgesic requirement and better patient satisfaction were obtained in the preincisional infiltration group.Discussion: Local anesthetic infiltration is a safe, practical method of pain management following thyroid surgery. Preincisional wound infiltration gives better results.

    Thyroid and parathyroid surgery is usually performed with the patient under general anesthesia; however, for selected patients regional anesthesia may be preferable. Between September 1977 and March 1986 regional anesthesia was used successfully as the sole anesthetic technique in 17 patients who underwent thyroid surgery and two patients who underwent parathyroid surgery. Procedures included two total thyroidectomies, 14 lobectomies or lobectomies with isthmusectomies, and one isthmusectomy. These 17 operations represent approximately 5% of the thyroid operations performed by the senior surgeon over the corresponding time. One patient underwent combined completion thyroidectomy and parathyroidectomy, and another patient underwent successful parathyroidectomy under regional anesthesia. In two additional patients, procedures could not be completed under regional anesthesia alone. In one of these two patients regional anesthesia appeared to effect a transient recurrent nerve paralysis. The indications for use of regional anesthesia have been primarily patient preference and associated cardiac or pulmonary disease. We now consider as contraindications to regional anesthesia patient apprehension about the technique, deafness, high spinal cord injury, recurrent laryngeal or phrenic nerve palsy, and allergy to local anesthesia. During this period, from 1977 to 1986, our administration of regional anesthesia has evolved from bilateral deep and superficial cervical plexus blocks to bilateral superficial blocks alone using bupivacaine with epinephrine, 1:200,000.

  6. Should patients with symptomatic Hashimoto's thyroiditis pursue surgery?

    2011-09-01

    In this study, patients with Hashimoto's Thyroiditis and significant symptoms were evaluated for improvement or resolution of preoperative symptoms after thyroidectomy. Hashimoto's thyroiditis (HT) is an organ-specific autoimmune disease characterized by production of antibodies such as anti-thyroperoxidase (TPO), which leads to destruction of the thyroid gland and a decrease in normal thyroid function. Thyroidectomy is not generally recommended because the dense inflammatory process that surrounds the thyroid gland can make resection more difficult. However, patients with HT are considered for surgery if they experience persistent symptoms after conservative therapy. We hypothesized that patients with HT and significant compressive and other associated symptoms may benefit from thyroidectomy for palliation. We identified 1791 patients who underwent thyroidectomy from May 1994 to December 2009. Of those 1791 patients, 311 were diagnosed with HT. Of these 311 patients, 133 had 170 significant preoperative symptoms, and served as our sample population. Patients were subjectively evaluated for improvement or relief of symptoms postoperatively. The mean age of the group was 46 ± 1 y, and 90% were female. Patients underwent lobectomy (33%), subtotal thyroidectomy (6%), or total thyroidectomy (61%). The overall rate of symptomatic improvement for HT patients was 90% after thyroidectomy. The most frequent preoperative symptom was compression, and >93% of patients experienced relief. In addition, we found high rates of improvement for HT patients with other preoperative symptoms including voice problems (77%), hormone imbalance (84%), and other (90%). The overwhelming majority of HT patients with significant symptoms appear to benefit from thyroidectomy. Therefore, HT patients should consider pursuing surgery for palliation if they suffer from persistent symptoms after conservative therapy. Copyright © 2011 Elsevier Inc. All rights reserved.

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

    The purpose of this paper is to provide a forensic profile framework of neuromonitoring in thyroid surgery, regarding the information given to the patient and its classification as part of professional liability in the event of recurrent injury. Evaluation and reflections on the required behaviour of the surgeon on providing details on the operation before the informed consent is given and to outline the possible legal implications regarding professional liability as a result of recurrent injury. In particular, if it is an obligation to inform the patient about using this method and if it is possible for the surgeon to freely choose whether to employ this method, which is still burdened by a certain percentage of error and for that reason it cannot be defined a "standard of care". To recognize neuromonitoring the role of standard of care in surgery of the thyroid means attribute a role of method able to avoid the surgeon to cause iatrogenic damage to the laryngeal nerve. For the foregoing reasons that is not true, determining false positives and false negatives, and this can be a double edged sword for the surgeon. Although the progress in the field of thyroid surgery made in the last decade, currently there is no scientific reassuring evidence to completely avoid the possibility of producing an iatrogenic lesion of the laryngeal nerve. Information given to the patient prior to surgery should respect the requirements of completeness, freedom and honesty in order to allow the patient to self-determination.

  10. The diagnosis of cancer in thyroid fine needle aspiration biopsy. Surgery, repeat biopsy or specimen consultation?

    2016-05-01

    Full Text Available Fine needle aspiration biopsy (FNA is the only diagnostic method that allows a preoperative diagnosis of thyroid carcinoma. An unequivocal diagnosis of a malignant change is achievable only in cases in which all cytological criteria of carcinoma are met. The aim of the study was to evaluate the necessity of repeat thyroid FNA in patients with papillary thyroid carcinoma verified on consultative examination (CE. We analyzed cytology reports of thyroid FNA and CE that resulted in the diagnosis of papillary carcinoma. Evaluation of the correlation of the cytological diagnosis with the histopathology report was based on data obtained after the surgery. Between 2010 and 2015 in the Institute of Oncology (IO there were 184 cancers diagnosed on CE or in thyroid FNA performed primarily in IO. Additionally, 74 patients were subjected to repeat biopsy after confirmation of cancer in CE. Histopathological diagnosis of cancer was obtained in 62 (100% cases that were doubly confirmed with cytological examination. The remaining 12 patients were operated on outside the institute. From 110 FNA primarily performed in the IO, histopathological verification was achievable in 92 cases, from which 92 (100% provided a confirmation of cancer, and the remaining 18 patients were operated on outside the institute. High (100% specificity of cancer diagnosis in FNA established primarily and verified on CE (second independent assessment indicates that repeat FNA in order to confirm the diagnosis is unnecessary.

    The use of microsurgical technique and loupes magnification as a support to traditional surgery can help surgical performance and prevent complications in thyroid surgery. Between January 2004 and December 2014, 782 patients with thyroid diseases were operated by our team with microsurgical technique and loupes magnification 4.5x. All patients had pre and postoperative vocal cords assessment and calcemia and the collected data were analysed. Among the 782 patients, only six patients (0.77%) had unilateral vocal fold immobility treated with medical therapy, phoniatric and neck physiotherapy. All six patients showed complete laryngeal recovery of motility 6/8 weeks after treatment. There were not cases of permanent monolateral or bilateral vocal cord palsy. In 84 patients there were signs and symptoms of hypocalcemia. In 81 patients (10.36%) the restoring of biochemical parameters and the resolution of symptoms occurred between 2 and 6 weeks and in 3 cases (0.38%) there was permanent hypocalcemia more than six months. The use of microsurgical technique and loupes magnification in thyroid surgery are safety and effective procedures, that require an appropriate training in reconstructive microsurgery, but may significantly reduce post-operative complications. Here, we report for the first time the largest series of thyroid surgery performed with the use of microsurgical technique and loupes magnification, analysing the postoperative morbidity. In view of our results, we suggest the routine use of 4.5X loupes and microsurgical technique in thyroid surgery.

    1994-01-01

    Hypothyroidism was diagnosed in a dog which had undergone unilateral thyroid lobectomy and external beam irradiation (48 Gy in 3 Gy fractions) for a functional cystic thyroid adenocarcinoma. Hypothyroidism became biochemically apparent within 4 months of completion of radiation therapy, and clinically apparent within 7 months. Clinical signs resolved after thyroid hormone supplementation. The potential for alterations in thyroid function should be considered in any animal undergoing radiation therapy in which the thyroid gland is included in the radiation field. This potential may be greater if surgery and radiation are combined

    Ninety-one patients with histologically proven anaplastic carcinoma of the thyroid were referred to the Beatson Oncology Centre between 1961 and 1986. The female:male ratio was 2.4:1 and the median age at presentation was 70 (range 38-92) years. All patients had a thyroid mass at presentation and the most common symptoms were dyspnoea, dyspnagia and dysphonia. Five patients had a total thyroidectomy and 28 partial thyroidectomy. Ninety five per cent of patients received external beam radiotherapy. Results show dyspnoea to be the only symptom strongly influencing survival. Total or partial thyroidectomy is associated with increased survival. This association is most marked for patients presenting without dyspnoea. Eighty per cent of patients responded to radiotherapy.

  17. Primary surgery for differentiated thyroid cancer in the new millennium.

    Differentiated thyroid cancers (DTC) are malignancies of follicular cell derivation. Histopathologically and oncologically, DTC fall into two broad tumor categories: papillary (PTC) and follicular thyroid cancer (FTC). These major tumor categories, based on clinical manifestation and biological behavior, are further subdivided into low-risk [papillary microcarcinoma (mPTC); minimally invasive follicular cancer (MIFTC)] and high-risk DTC [PTC>1 cm or metastatic; MIFTC with histopathological angioinvasion; widely invasive FTC (WIFTC)]. Recently, a surgical approach has been adopted that differentiates between low-risk and high-risk DTC. The rationale behind this new concept is to better balance oncologic risk (high vs low) with the surgical morbidity attendant to the procedure (recurrent laryngeal nerve palsy and hypoparathyroidism). This surgical risk is larger with routine total thyroidectomy (TT) and central node dissection (CND) than with less than TT or TT without CND.Whereas TT with CND remains the treatment of choice for high-risk DTC with metastases, the extent of thyroid resection and lymph node dissection can be reduced in low-risk PTC and FTC without demonstrable loss of oncological benefit. In the new millennium, the surgical approach to DTC, especially low-risk PTC and FTC, has undergone considerable change, resulting in less extensive procedures. This risk-adapted strategy relies not only on the skillful histopathologic detection of multifocality in PTC and vascular invasion in MIFTC, but likewise necessitates diligent follow-up to spot and adequately treat local recurrences and distant metastases as they become clinically apparent.

    In 1993, the Ukrainian Ministry on Chernobyl Affairs initiated a large scale reconstruction of thyroid exposures to radioiodine after the Chernobyl accident. The objective was to provide the state policy on social compensations with a scientific background. About 7000 settlements from five contaminated regions have gotten certificates of thyroid exposure since then. Certificates contain estimates of the average thyroid dose from 131 I for seven age groups. The primary dose estimates used about 150000 direct measurements of the 131 I activity in the thyroid glands of inhabitants from Chernigiv, Kiev, Zhytomyr, and also Vinnytsa regions. Parameters of the assumed intake function were related to environmental and questionnaire data. The dose reconstruction for the remaining territory was based on empirical relations between intake function parameters and the 137 Cs deposition. The relationship was specified by the distance and the direction to the Chernobyl Nuclear Power Plant. The relations were first derived for territories with direct measurements and then they were spread on other areas using daily iodine releases and atmospheric transportation routes. The results of the dose reconstruction allowed to mark zones on the territory of Ukraine according to the average levels of thyroid exposures. These zones underlay a policy of post-accidental health care and social compensations. Another important application of the thyroid dose reconstruction is the radiation risk assessment of thyroid cancer among people exposed during childhood due to the Chernobyl accident

    Full Text Available Levothyroxine therapy with purpose to suppress thyroid stimulating hormone (TSH after surgery in patients with well-differentiated thyroid cancer is implemented since 1937. Accumulated results of levothyroxine suppressive therapy (LST application are attesting its heterogeneous efficacy in various risk groups of tumor recurrence: low, medium and high. Similar risk groups are emphasized towards adverse effect risk due to LST. The more intensivity and duration of TSH suppression the higher risk of adverse effects. First, they include osteopenia or osteoporosis and atrial fibrillation. Contemporary approaches to intensivity and duration of LTS are based on accounting of its potential efficiency into various clinical risk groups of tumor recurrence as well as adverse effects risk groups.

    Objective: To discuss the functional recovery after recurrent laryngeal nerve injury (RLNI) on different electromyography thresholds during thyroid surgery. Methods: The prospective experimentally were induced in 12 acute recurrent laryngeal traction animals (porcine) from December 2014 to December 2015, the amplitude and latency of electromyography, even time course during RLNI and recovery of 24 recurrent laryngeal nerves(RLN) were continuous intraoperative neuromonitoring(IONM), including 12 RLN releasing traction after 50% amplitude decrease (AD) and other 12 RLN after 70% AD. The IONM data and postoperative laryngoscopy result of 1 119 thyroid cancer patients, involved 237 male and 882 female, aged 45.2 years in average, who underwent thyroidectomy in Department of Thyroid Surgery, China-Japan Union Hospital Affiliated to Jilin University from July to December in 2016 were analyzed retrospectively. Results: The porcine model of traction lesion showed that the time of 50% AD was (59±4) s, latency increase (LI) was (8± 4)%, was recovered in 10 minutes; the time of 70% AD was (75±6)s, LI was (11±5)% , was recovered (43±23)% of baseline even during 20 minutes. Among the IONM of 1 632 recurrent laryngeal nerves in clinic, the mechanism of 64 RLNI is clear, including traction injury accounted for 62.5% (40/64), thermal injury was 12.5% (8/64), compression injury was 23.4% (15/64), clamp injury was 1.6% (1/64). When 50%≤AD injury before AD≥50% in surgery, is a more effective indicator to avoid postoperative AVCM and promote nerve function recovery.

    Full Text Available Unilateral vocal fold paralysis (UVFP is one of the most serious problems in conducting surgery for thyroid cancer. Different treatments are available for the management of UVFP including intracordal injection, type I thyroplasty, arytenoid adduction, and laryngeal reinnervations. The effects of immediate recurrent laryngeal nerve (RLN reconstruction during thyroid cancer surgery with or without UVFP before the surgery were evaluated with videostroboscopic, aerodynamic, and perceptual analyses. All subjects experienced postoperative improvements in voice quality. Particularly, aerodynamic analysis showed that the values for all patients entered normal ranges in both patients with and without UVFP before surgery. Immediate RLN reconstruction has the potential to restore a normal or near-normal voice by returning thyroarytenoid muscle tone and bulk seen with vocal fold denervation. Immediate RLN reconstruction is an efficient and effective approach to the management of RLN resection during surgery for thyroid cancer.

    After the Fukushima nuclear power plant accident on March 11, 2011, the public of Japan became particularly concerned about the possibility of an increased risk of childhood thyroid cancer, similar to what was observed after the Chernobyl's accident. Due to serious public health perception, there was an urgency to evaluate the baseline levels of childhood thyroid status in Fukushima prefecture. Therefore we have commenced a thyroid ultrasound examination (TUE) survey of the approximately 360,000 pediatric inhabitants (0 to 18 years of age) who lived in Fukushima at the time of the accident in October 2011. The subjects were divided into three categories according to the standardized diagnostic criteria of ultrasound findings. Category A contained the subjects whose TUE findings were intact or benign. Category B were recommended a confirmatory TUE. Category C was recommended an immediate confirmatory TUE. The survey of 40,302 subjects in the first year was completed in March, 2013. There were 40,097 (99.5%), 205 (0.50%) and 0 subjects in categories A, B and C, respectively. Of the 82 category B subjects who underwent fine needle aspiration cytology (FNAC), 12 were diagnosed with a malignant tumor or were suspected to have malignancy. The 12 subjects received thyroid surgery and 11 thyroid cancers and one benign nodule were confirmed histologically after surgery. This is the first large-scaled TUE survey to employ sophisticated ultrasound screening and aim to evaluate the baseline frequency of childhood thyroid nodules and cysts. The results will become the golden standard of future comparative TUE in Fukushima, Japan.

    Full Text Available Abstract Background Nowadays, the increasing number of oncologic patients with liver or pancreatic tumours are subjected to surgical treatment, as it can provide a long-term survival or sometimes cure. As a result, numerous new clinical questions regarding metabolic disturbances in these patients have been arisen. Among others, the impact of the pancreas and liver surgery extent in relation to the thyroid function remains to be elucidated. Materials and methods The study comprised 51 patients (25 men and 26 women, mean age ± SD 61.6 ± 10.4 yrs, mean ± SD with pancreatic or liver tumours, qualified for abdominal operation. Serum levels of FT3, FT4 and TSH were measured on the day before (time “0” and on the 1st, 3rd and 5th day after surgery in two (2 subgroups reflecting the extent of surgery: twenty seven (27 patients (14 men and 13 women, mean age ± SD 61.5 ± 11.8 yrs after major surgery (Whipple’s surgery, right and left hemihepatectomy, segmentectomy of the liver, distal pancreatectomy, total duodenopancreatectomy and twenty four (24 patients (11 men and 13 women, mean age ± SD 61.8 ± 8.9 yrs after minor, palliative surgery (exploratory laparotomy, gastroenterostomy, triple by-pass, liver tumour embolization, hepaticojejunostomy. Additionally, the obtained results were analyzed in relation to the type of the disease (pancreatic surgery vs liver surgery. Results Mean serum FT3 level decreased significantly during the study in major and minor surgery subgroups (prd and 5th day after major surgery was lower in pancreatic tumour patients in comparison to liver tumour patients (p=0.002, p=0.032, respectively.

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

Methods: A group of 63 patients, who were graded as American Society of Anaesthesiologists physical status (ASA I-II and in whom a thyroid surgery was planned, were randomly divided into 3 groups: the patients in Group D (n=21, Group T (n=21 and Group K (n=21 received 50 mg (2ml of dexketoprofen, 100 mg (2 ml of tramadol and 2 ml 0.9% NaCl serum, respectively, before surgery. Standard anesthesia monitoring, induction and maintenance was performed in all patients. At the end of the surgery, the incision line was infiltrated with bupivacaine in all patients. Visual analogue scale (VAS scores (0: no pain,10: worst pain ever were recorded in all groups at the beginning (in the recovery room, at the 1st, 6th, 12th and 24th hour post-operatively. Nausea-vomiting, head and neck pain, sore throat, dizziness and other possible side-effects were also asked and recorded. Results: VAS scores were statistically higher in Group K than in Group T and Group D at the 1st, 6th, 12th, and 24th hours postoperatively. There was no significant difference between Group T and Group D in VAS scores evaluated at all time points.. The fentanyl consumption in Group K was higher than in the other two groups. The incidence of headache, sore throat nausea, vomiting was higher in Group K compared with that in Group T and Group D. Conclusion: We determined that preoperative tramadol and dexketoprofen had similar analgesic effect and dexketoprofen caused less side-effects. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 5-9

    2006-09-01

    Full Text Available Abstract Background Annually, more than 90000 surgical procedures of the thyroid gland are performed in Germany. Strategies aimed at reducing the duration of the surgical procedure are relevant to patients and the health care system especially in the context of reducing costs. However, new techniques for quick and safe hemostasis have to be tested in clinically relevance randomized controlled trials before a general recommendation can be given. The current standard for occlusion of blood vessels in thyroid surgery is ligatures. Vascular clips may be a safe alternative but have not been investigated in a large RCT. Methods/design CLIVIT (Clips versus Ligatures in Thyroid Surgery is an investigator initiated, multicenter, patient-blinded, two-group parallel relevance randomized controlled trial designed by the Study Center of the German Surgical Society. Patients scheduled for elective resection of at least two third of the gland for benign thyroid disease are eligible for participation. After surgical exploration patients are randomized intraoperatively into either the conventional ligature group, or into the clip group. The primary objective is to test for a relevant reduction in operating time (at least 15 min when using the clip technique. Since April 2004, 121 of the totally required 420 patients were randomized in five centers. Discussion As in all trials the different forms of bias have to be considered, and as in this case, a surgical trial, the role of surgical expertise plays a key role, and will be documented and analyzed separately. This is the first randomized controlled multicenter relevance trial to compare different vessel occlusion techniques in thyroid surgery with adequate power and other detailed information about the design as well as framework. If significant, the results might be generalized and may change the current surgical practice.

    The aim of this study was to test two different video cameras and recording systems used in thyroid surgery in our Department. This is meant to be an attempt to record the real point of view of the magnified vision of surgeon, so as to make the viewer aware of the difference with the naked eye vision. In this retrospective study, we recorded and compared twenty thyroidectomies performed using loupes magnification and microsurgical technique: ten were recorded with GoPro ® 4 Session action cam (commercially available) and ten with our new prototype of head mounted video camera. Settings were selected before surgery for both cameras. The recording time is about from 1 to 2 h for GoPro ® and from 3 to 5 h for our prototype. The average time of preparation to fit the camera on the surgeon's head and set the functionality is about 5 min for GoPro ® and 7-8 min for the prototype, mostly due to HDMI wiring cable. Videos recorded with the prototype require no further editing, which is mandatory for videos recorded with GoPro ® to highlight the surgical details. the present study showed that our prototype of video camera, compared with GoPro ® 4 Session, guarantees best results in terms of surgical video recording quality, provides to the viewer the exact perspective of the microsurgeon and shows accurately his magnified view through the loupes in thyroid surgery. These recordings are surgical aids for teaching and education and might be a method of self-analysis of surgical technique. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

    Nodular goiter is one of the most common benign lesions in thyroid nodule. The main treatment of the disease is still the traditional surgical resection, however there are many problems such as general anesthesia, surgical scar, postoperative thyroid or parathyroid function abnormalities, and high nodules recurrence rate in residual gland. The purpose of this study was to compare the efficacy, safety, and cost-effectiveness of 2 treatment methods, surgery and radiofrequency ablation, for the treatment of benign thyroid nodules. From May 2012 to September 2013, 200 patients with nodular goiters who underwent surgery (group A) and 200 patients treated by radiofrequency ablation (group B) were enrolled in this study. Inclusion criteria were the following: 1) cosmetic problem, 2) nodule-related symptoms, 3) hyperfunctioning nodules related to thyrotoxicosis, and 4) refusal of surgery (for group B). An internally cooled radiofrequency ablation system and an 18-ga internally cooled electrode were used. We compared the 2 groups in terms of efficacy, safety, and cost-effectiveness during a 1-year follow-up. After radiofrequency ablation, the nodule volume decreased significantly from 5.4 to 0.4 mL (P = .002) at the 12-month follow-up. The incidence of complications was significantly higher from surgery than from radiofrequency ablation (6.0% versus 1.0%, P = .002). Hypothyroidism was detected in 71.5% of patients after surgery but in none following radiofrequency ablation. The rate of residual nodules (11.9% versus 2.9%, P = .004) and hospitalization days was significantly greater after surgery (6.6 versus 2.1 days, P radiofrequency ablation are both effective treatments of nodular goiter. Compared with surgery, the advantages of radiofrequency ablation include fewer complications, preservation of thyroid function, and fewer hospitalization days. Therefore, radiofrequency ablation should be considered a first-line treatment for benign thyroid nodules. © 2015 by American

    Objective: To compare the frequency of recurrent laryngeal nerve(s) (RLNs) palsy after various thyroid procedures with and without identification of recurrent laryngeal nerve during the operation. Study Design: Randomized controlled trial. Place and Duration of Study: Department of Surgery, Military Hospital, Rawalpindi, from August 2008 to April 2010. Methodology: Patients undergoing indirect laryngoscopy with normal vocal cords and those with carcinoma and re-do surgery having normal vocal cord were included in the study. Patients with hoarseness of voice, abnormal vocal cord movements and with solitary nodule in the isthmus were excluded. These patients were randomly divided into 2 groups of 50 each using random number tables. RLN was identified by exposing the inferior thyroid artery and traced along its entire course in group-A. Whereas, in group-B, nerves were not identified during the operations. Immediate postoperative direct laryngoscopy was performed by a surgeon with the help of an anaesthesiologist for the assessment of vocal cords. Patients with persistent hoarseness of voice were followed-up with indirect laryngoscopy at 3 and 6 months. Results: Temporary unilateral recurrent laryngeal nerve palsies occurred in 2 (4%) patients in group-A where the voice and cord movements returned to normal in 6 months. In group-B, it occurred in 8 (16%) patients, 2 bilateral (4%) injuries requiring tracheostomy and 6 unilateral injuries (12%). Among the 2 bilateral recurrent laryngeal nerve injuries, the tracheostomy was removed in one case after 6 months with persistent hoarseness of voice but no respiratory difficulty during routine activities. Tracheostomy was permanent in the other case. Among the 6 cases of unilateral nerve injuries, the voice improved considerably in 4 cases within 6 months but in 2 cases hoarseness persisted even after 6 months. Frequency of recurrent laryngeal nerve palsies was significantly lower in group-A as compared to group-B (p = 0

Life-threatening complications, arising from post-operative haematomas, mandates their utilization. There is increasing evidence to suggest that this is an outdated practice. This paper determines whether thyroid surgery can be safely performed without the routine use of drains. A retrospective review of patients undergoing thyroid surgery, over a three year period was performed and post-operative complications documented. One hundred and four thyroidectomies were performed. 63 (60.6%) patients had a partial thyroidectomy, 27 (25.9%) had a total thyroidectomy and 14 (13.5%) had a sub-total thyroidectomy. Suction drains were not inserted in any patient. A cervical haematoma did not develop in any patient in this series and no patient required re-operation. There is no evidence to suggest the routine use of surgical drains following uncomplicated thyroid surgery reduces the rate of haematoma formation or re-operation rates and indeed is now unwarranted.

    Abstract The aim of this study was to determine the effects of nanocarbon particles in combination with meticulous capsular dissection on enhancing the identification and protecting the function of parathyroid glands in thyroid cancer surgery. The data of 97 patients with papillary thyroid tumors diagnosed and treated at the Second Affiliated Hospital, Harbin Medical University between January 2014 and February 2015 were reviewed. Data regarding the sex, age, calcium and parathyroid hormone (PTH) levels, tumor size, multifocality, T stage, and extrathyroid invasion were collected. The incidence of surgeries in which the parathyroid glands were cut mistakenly, the concentration of serum calcium and parathyroid hormone before surgery (baseline) and after surgery on days 1, 3, and 7, and 1 and 6 months in the patients of the two groups (the nanocarbon and control groups) were analyzed. Fifty-two patients underwent meticulous capsular dissection combined with nanocarbon treatment (nanocarbon group), and 45 underwent meticulous capsular dissection alone (control group). The nanocarbon group showed a significantly higher total and average number of revealed parathyroid glands (average number is the mean for different individuals have different number) and a lower incidence of the parathyroid glands being mistakenly cut, in addition to a lower level of hypoparathyroidism than control group following surgery (P parathyroid in thyroid cancer surgery, reduce the risk of mistakenly cutting the parathyroid, and reduce the incidence of postoperative hypoparathyroidism.

    Cricothyroid (CT) muscle twitch inspection with neurostimulation is a widely accepted method to identify the external branch of the superior laryngeal nerve (EBSLN) and its integrity in thyroid surgery. However, there has been no large-scale research to evaluate the diagnostic values of CT muscle twitch inspection based on postoperative electromyography (EMG) results, which are considered the gold standard. In this study, we aimed to demonstrate the diagnostic value of CT muscle twitch inspection based on postoperative EMG. Prospective cohort study. A total of 454 patients underwent primary thyroid surgery. Among them, 55 patients were excluded because of preoperative vocal fold palsy, problems with the stimulator, or refusal to participate in the EMG study. Finally, 399 patients were prospectively enrolled in this study. Intraoperatively, CT muscle twitch was inspected with neurostimulation. Bilateral EMG examination of the CT muscle was performed 2 to 3 months postoperatively in all patients. A total of 712 EBSLNs at risk were analyzed in this study. Of these, 21 (2.9%) nerves were visually identified, and positive CT muscle twitch by neurostimulation was observed in 694 (97.5%). Normal results on postoperative EMG of the CT muscle were reported in 657 (92.3%). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 97.7%, 5.5%, 92.5%, and 16.7%, respectively. CT muscle twitch inspection could be a useful intraoperative tool to determine EBSLN integrity considering its high sensitivity and PPV. However, the test may not completely replace EMG for evaluating EBSLN integrity due to its low specificity and NPV. 2b.

    The aim of this study was to investigate ultrasound (US) findings of eggshell calcified thyroid nodules associated with thyroid malignancy and the diagnostic usefulness for US-guided fine-needle aspiration cytology (US-FNAC) of eggshell calcified thyroid nodules. We analyzed 36 eggshell calcified thyroid nodules in 35 patients who underwent thyroid US and US-FNAC from January to December of 2009. We compared the US findings and US-FNAC results with the pathologic results confirmed by surgery. Twenty eggshell calcified nodules were surgically removed in 19 patients, from which 8 papillary thyroid carcinomas and 12 hyperplasia nodules were confirmed. The sensitivity, specificity, positive, and negative predictive values, as well as accuracy for US diagnosis and US-FNAC of eggshell calcified nodules were 100% and 20%, 25% and 100%, 43.8% and 100%, 100% and 63.6%, and 55% and 66.7%, respectively. The results of this study indicate that thick peripheral hypoechoic rim and thickening of eggshell calcified nodules are significantly related to malignancy, but focal disruption of eggshell calcification is not.

    Medical costs in the United States have been increasing disproportionally to gross domestic product, raising concerns about the sustainability of U.S. healthcare expenditures. Care of patients with thyroid disease has been identified as an area of medicine where cost increases have been pronounced. The goals of this study were to identify potential drivers of the cost of hospitalization following thyroid surgery, and to understand which of these factors may be contributing to observed increases in cost from 2003 to 2011. A retrospective cross-sectional analysis of discharge data from the Nationwide Inpatient Sample (NIS) database for all admissions following thyroid lobectomy or total thyroidectomy in the years 2003, 2007, and 2011 was performed. Multiple regression analysis via a weighted generalized linear model was used to identify factors that were independently associated with high cost of hospitalization. Trend as well as subgroup analyses were then performed to identify which of these factors could be contributing to increasing costs. There were 47,854 hospital admissions following total thyroidectomy or thyroid lobectomy identified in the years 2003, 2007, and 2011. The aggregate national cost of hospitalization increased from $198 million in 2003 to $373 million in 2011 in inflation-adjusted 2011 dollars. The weighted mean cost of hospitalization following thyroid surgery increased from $6154 to $8982 from 2003 to 2011 in inflation-adjusted 2011 dollars. Higher comorbidity score, total thyroidectomy, lymphadenectomy, western region, rural region, and certain postoperative complications were the factors most highly associated with increased hospital costs. Of these, an increasing proportion of patients with higher severity of illness score and an increasing proportion of patients undergoing total thyroidectomy and lymphadenectomy were implicated as the most likely contributors to the cost increases. The rate of total thyroidectomy and lymphadenectomy was

    Full Text Available Background: The use of bilateral superficial cervical plexus block (BSCPB to provide analgesia for thyroid operations remains debatable. This study was done to assess the analgesic efficacy and safety of ultrasound (US guided or landmark-based BSCPB, performed under general anesthesia, compared to systemic narcotics in thyroid surgery. Patients and methods: A total of 69 patients ASA I and II scheduled for thyroid surgery were randomly assigned into three groups (23 patients each: Group (US received US guided BSCPB. Group (LM received landmark-based BSCPB. In both groups, the block was performed under general anesthesia and before surgery using 0.5% bupivacaine 12 ml on each side. Group (C who didn’t receive any block. We measured intra-operative hemodynamics and fentanyl requirements. We also measured postoperative analgesia within 24 h of surgery as regard: pethidine consumption, visual analogue scale (VAS pain scores and time to first rescue analgesic demand. Postoperative nausea and vomiting (PONV and other adverse events were noted as well. Results: There was a significant reduction in systolic blood pressure (SBP and heart rate (HR in groups US and LM compared with group C. Intra-operative fentanyl requirements were significantly increased in group C compared to groups US and LM. Time to first analgesic request was significantly longer in groups US and LM than in group C. Postoperative pethidine consumption and VAS scores, measured during the first postoperative day, were significantly higher in group C than groups US and LM. No significant difference was noted between the three groups regarding PONV. No other adverse events were recorded. No significant differences were noted between groups US and LM. Conclusion: BSCPB (US guided or landmark-based, performed under general anesthesia, effectively decreased peri-operative analgesic requirements in thyroid operations. However, there was no significant difference in analgesic efficacy or

    The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

    208 patients with thyroid gland cancer were observed in 1975-1993 . The morphological investigations point to an absolute prevalence of highly differentiated forms of thyroid gland cancer in children. The radiation diagnostic techniques included ultrasound investigations of neck organs, chest roentgenography, thyroid gland scintigraphy. It is shown that the surgical method is the basic technique of treating thyroid gland cancer in children. 5-year survival rate of patients depending on the stage of disease development and scope of surgical treatment is analysed

    Full Text Available Purpose. The aim of the study was to compare the risk of thyroid malignancy and efficacy of repeat FNA in patients with thyroid nodules diagnosed cytologically as benign lesion (BL with features of chronic thyroiditis (BL-CT and BL without CT features (BL-nCT. Methods. The analysis included 917 patients with BL-CT and 7046 with BL-nCT in the first FNA. Repeat biopsy was carried out in 787 patients of BL-CT and 5147 of BL-nCT; 218 patients of BL-CT and 2462 of BL-nCT were operated; in 88 cases of BL-CT and 563 of BL-nCT both ways of follow-up were available. Results. Outcome of repeat cytology implied surgery more frequently in patients with BL-CT than with BL-nCT—3.2% versus 1.9%, P < 0.05. Incidence of cancer (including incidentalomas was higher in patients with BL-CT operated after one benign cytology than in patients with two benign FNA outcomes: 10.8% versus 1.6%, P < 0.05. In patients with BL-nCT that difference was not significant: 3.2% versus 2.6%. Conclusions. Patients with thyroid nodules diagnosed as BL with CT features have higher risk of malignancy than patients with BL without CT features. Repeat biopsy significantly lowers percentage of FN results in patients with BL-CT in the first FNA.

    To compare the advantages and disadvantages of real time recurrent laryngeal nerve (RLN) monitoring and conventional exposure during thyroid operation by Meta analysis. The published articles of randomized controlled clinical trials were searched in data bases to compare the therapeutic outcomes of using real-time RLN monitoring and conventional exposure in thyroid surgery. The quality of the searched original studies was assessed and the outcomes which are in line with the requirements were analyzed. Six articles met the inclusion criteria, which contained 12,646 RLN in total. There were 5,535 cases in the RLN monitoring group and 7,111 cases in the conventional exposure group. The results of Meta analysis showed that: the transient injury rate of the RLN in the monitoring group (OR=0.60, 95% CI=0.49-0.73, Pinjury rate of the RLN in two groups had no statistical difference (OR=0.90, 95 % CI= 0.57-1.40, P>0.05). The RLN identification rate also had no statistical difference between the two groups (OR=9.79, 95% CI=0.17-548. 64, P>0.05). The transient injury rate of the RLN is lower in the monitoring group than that in conventional exposure group, but the permanent injury rate and the RLN identification rate had no statistical difference between the two groups. The intraoperative nerve monitoring was useful in the prevention of the RLN injury in thyroid surgery.

    The aim of this study was to evaluate whether malignant-looking thyroid nodules with size reduction were malignant or not. From November 2010 to July 2011, we retrospectively enrolled 16 patients with 16 nodules (11 females and five males; mean age, 55 years) who underwent core needle biopsy (CNB), and whose thyroid nodules had malignant ultrasonographic (US) features, although they showed size reduction (>20% decrease in maximum diameter) during the follow-up period (mean, 37±27 months). The histologic findings of the CNB specimen were reviewed and correlated with the US findings. US studies were analyzed for their internal content, shape, margin, echogenicity, the presence of microcalcification and macrocalcification, inner isoechoic rim, and low-echoic halo. All nodules were confirmed as benign by CNB. Pathologic analysis was available for 12 CNB specimens. US imaging showed central hypoechogenicity or marked hypoechogenicity in all cases and a peripheral isoechoic rim in 15 nodules. US-pathologic correlation showed that the central hypoechoic area was primarily composed of fibrosis (12/12) and hemorrhage (8/12) and that the isoechoic rim was composed of follicular cells. In our study, the CNB results of all of the malignant-looking thyroid nodules with size reduction were benign and were primarily composed of internal fibrosis and hemorrhage. Understanding these US and pathologic features could prevent repeated fine-needle aspiration or unnecessary diagnostic surgery.

    To observe the changes of perioperative serum thyroid hormone and their clinical significance, blood samples were obtained from 20 patients before, during and after heart operations. Thyroid hormones were measured by radioimmunoassay. The results showed that serum T 3 , T 4 and FT 3 levels significantly declined during cardiopulmonary bypass (CPB) and thereafter. Serum T 3 and T 4 concentrations reached their nadir at the lowest hypothermia of CPB. TSH and FT 4 levels remained normal ranges at postoperative sampling times. Conclusions: CPB would severely affect patients' thyroid function, thus simulated a 'low T 3 syndrome', and low T 3 syndrome would produce side effects on postoperative heart function

    Endoscopic surgery for treatment of thyroid and parathyroid pathologies is increasingly gaining attention. The da Vinci system has already been widely used in different fields of medicine and quite recently in thyroid and parathyroid surgery. Herein, we report about modifications of the transaxillary approach in endoscopic surgery of thyroid and parathyroid gland pathologies using the da Vinci system. 16 patients suffering from struma nodosa in 14 cases and parathyroid adenomas in two cases were treated using the da Vinci system at the ENT Department of Homburg/Saar University and in cooperation with the Department of General Surgery in New Sant'Agostino Hospital, Modena/Italy. Two different retractors, endoscopic preparation of the access and three different incision modalities were used. The endoscopic preparation of the access allowed us to have a better view during preparation and reduced surgical time compared to the use of a headlamp. To introduce the da Vinci instruments at the end of the access preparation, the skin incisions were over the axilla with one incision in eight patients, two incisions in four patients and three incisions in a further four patients. The two and three skin incisions modality allowed introduction of the da Vinci instruments without arm conflicts. The use of a new retractor (Modena retractor) compared to a self-developed retractor made it easier during the endoscopic preparation of the access and the reposition of the retractor. The scar was hidden in the axilla and independent of the incisions selected, the cosmetic findings were judged by the patients to be excellent. The neurovascular structures such as inferior laryngeal nerve, superior laryngeal nerve and vessels, as well as the different pathologies, were clearly 3D visualized in all 16 cases. No paralysis of the vocal cord was observed. All patients had a benign pathology in their histological examination. The endoscopic surgery of the thyroid and parathyroid gland can be

    The European Working Time Directive has increased the need for surgical skills training which does not involve patients. Recent changes in the anatomy legislation now make it possible to perform surgical procedures on human cadavers. Standard formalin embalming, however does not provide a very realistic model and alternative approaches, such as Thiel soft-fix embalmed cadavers, should be explored and evaluated. Two formalin and 3 Thiel embalmed cadavers were used at a senior trainee and consultant course in thyroid surgery. The 12 participants (8 trainees and 4 consultants) were asked to score 15 aspects, such as quality of different tissues, for each type of cadaver. Some of these aspects were specific to thyroid surgery, however many are equally applicable to other specialties. All participants rated the Thiel embalmed cadavers better or equal for all aspects. Of the 180 pairs of scores 33 were excluded, 10 were equal for formalin and Thiel, while in the remaining 137 Thiel scored better. The preference was particularly pronounced in aspects that require flexibility of tissues such as flap raising. Thiel embalmed cadavers provide a more realistic model for training of thyroid surgical skills; this is expected to be similar for many other types of surgery.

    The vast majority of studies published on robot-assisted thyroid surgery are South Korean. This study aims to assess the impact of certain anthropometric parameters on performing robot-assisted thyroid surgery on Caucasian patients. A total of 91 patients underwent robot-assisted surgery by the axillary approach in the Fifth Surgical Clinic, City Hospital Cluj-Napoca, between 2010 and 2015. Besides the specific clinical and pathological parameters, a series of anthropometric parameters and the postoperative occurrence of skin disorders in the cervical or subclavicular region were determined for each patient. There was an increase in dissection time and console time, which was directly proportional to the patients' body mass index. There were no statistically significant differences in the incidence of postoperative complications in patients with different body mass indices. The postoperative drainage volume was significantly higher in overweight or obese patients. The time needed to visualize the thyroid lodge was longer in patients with wider shoulders, and there was a negative correlation between neck length and console time. A statistically significant direct correlation was found between the clavicle length-neck length ratio and the duration of the entire intervention. There was no significant influence of any of these parameters on the duration of hospitalization or the occurrence of other postoperative complications. The nutritional status of the patients and the other anthropometric parameters influenced the duration and difficulty of the intervention, without affecting its safety in terms of intra- and postoperative- complications.

    Thyroid nodules and cancers are rare in children compared with adults. However, after the 1986 Chernobyl Nuclear Power Plant accident, a rapid increase in childhood thyroid cancer was observed. To avoid any confusion and misunderstanding of data obtained in Fukushima after the 2011 nuclear accident, baseline prevalence of thyroid nodules and cancers should be carefully assessed with standardized criteria systematically, and comprehensively applied to the population perceived to be at risk. Under the official framework of the Fukushima Health Management Survey, the thyroids of children in Fukushima were examined using ultrasound, and the results collected in the first four years after the nuclear accident were analyzed in order to establish a baseline prevalence of childhood thyroid abnormalities, especially cancer. Of 367,685 people aged 18 years or younger as of April 1, 2011, who were living in Fukushima Prefecture at the time of the accident, 300,476 underwent thyroid ultrasound screening. Of those, 2108 subjects with thyroid nodules were further examined using an advanced ultrasound instrument, with standardized criteria applied to determine the need for fine-needle aspiration cytology (FNAC). FNAC results determined the need for surgery and histological confirmation of the cytological diagnosis. Of the 2108 rescreened subjects, 543 underwent FNAC, of whom 113 were diagnosed with malignancy or suspected malignancy. Subsequently, 99 patients underwent surgical resection, revealing 95 cases of papillary thyroid cancer, three poorly differentiated cancers, and one benign nodule. The overall prevalence of childhood thyroid cancer in Fukushima was determined to be 37.3 per 100,000 with no significant differences between evacuated and non-evacuated areas. Thyroid cancer patients had external exposure estimates of first four months. The high prevalence of childhood thyroid cancer detected in this four-year study in Fukushima can be attributed to mass screening. It

    Patients with concomitant thyroid pathology are usually excluded from minimally invasive radioguided parathyroidectomy (MIRP). We assessed the value in these patients of the gamma probe, alone or in combination with other techniques, in MIRP and unilateral or bilateral approaches. We evaluated its performance in association with intraoperative determination of intact parathyroid hormone (ioPTHi) and preoperative {sup 99m}Tc-MIBI dual phase scintigraphy. Included in the study were 87 patients with a diagnosis of primary hyperparathyroidism who underwent radioguided surgery. They were divided into two groups depending on the presence of concomitant thyroid pathology (TP group, 33 patients) or absence of concomitant thyroid pathology (NTP group, 54 patients). In the TP group, ioPTHi achieved the highest accuracy (90.9%), followed by the gamma probe (81.8%) and scintigraphy (69.7%). In the NTP group, the probe (94.4%) performed better than ioPTH and scintigraphy (both 85.2%). In the TP group, scintigraphy in combination with the gamma probe had a success rate of 90.9%, and 94% in combination with ioPTHi. The three techniques are applied together had a success rate of 97%. For all patients undergoing MIRP, the probe alone worked well, irrespective of the presence or absence of concomitant thyroid pathology. Patients with concomitant thyroid pathology should not be a priori excluded from a MIRP, as long as other adjuvant techniques (scintigraphy or ioPTHi) are used in conjunction with the gamma probe. In these patients, the probe can also be helpful in unilateral or bilateral surgery. (orig.)

    Relatively large numbers of patients complain of lower-pitched voices after thyroidectomy. However, little is known about the risk factors for, prognosis of, or progression over time of, such changes, in female patients. We analyzed the data of 217 patients who underwent thyroid surgery and postoperative (2 weeks, and 3, 6, and 12 months after surgery) voice work-ups. To identify patients with lower-pitched voices, speaking fundamental frequencies (SFFs) were compared before and after surgery. The change was calculated for all patients (postoperative change in SFF, ΔSFF). The mean ΔSFF was 8.35 ± 17.06 Hz and significant changes in voice pitch (ΔSFF ≥12 Hz) were evident in 93 (42.85 %) patients after surgery, mostly within 6 months, and only 18.4 % of patients had lower-pitched voices 1 year after surgery. On multivariate analysis, age (≥52 vs. <52 years) and extent of surgery remained significant predictors of lower-pitched voice after surgery. The ΔSFFs of older patients (≥52) were significantly greater than those of younger patients (<52) at the 2-week follow-up, but not at the 3-, 6-, or 12-month follow-ups. The ΔSFFs of patients who underwent total thyroidectomy were significantly higher than those who underwent lobectomy at the postoperative 2-week follow-up, but did not differ at the 3-, 6-, and 12-month follow-ups. Patients frequently experience a lower-pitched voice after thyroid surgery. Such problems develop more frequently in the early postoperative period, in aged patients, and in those who had undergone total thyroidectomy. However, over time, the changes usually decrease to levels similar to those of patients without these risk factors.

    The aim of this study is to demonstrate our experience at a volunteer surgical program in Cameroon, which is of special interest given to the inability to adopt international treatment guidelines for thyroid surgery in areas of limited resources due to the lack of preoperative testing and to the difficulty to obtain sustitutive hormonal treatment. This is a prospective observational study that includes 16 cases of thyroid surgery in Dschang (Cameroon) during June 2015. The patients were previously selected by a local medical team. All patients were black, 15 women and one man, with a mean age of 41 years. The surgical technique used for the removal of unilateral disease was hemithyroidectomy with isthmectomy and bilateral subtotal thyroidectomy for bilateral disease. Five subtotal thyroidectomies, 9hemithyroidectomies and 2isthmectomies were performed. Prethyroid muscles were divided only in one case. We visualized 86% of the parathyroid glands and 84% of the recurrent laryngeal nerves. The main complications observed were one symptomatic cervical haematoma that required reoperation and 2surgical wound infections. There were no clinical episodes of hypocalemia or recurrent nerve lesion. The mean length of stay was 2.3 days. At follow-up, all bilateral thyroidectomies developed high TSH levels. Thyroid surgery is safe in developing countries adopting protocols and techniques we use in our environment (avoiding total thyroidectomy). Bilateral thyroidectomies should not be performed unless functional studies are available in the follow-up and a thyroid hormone supplement stock guaranteed whenever necessary. Copyright © 2016 AEC.

IOP measurement during the postoperative periods was classified based on the postoperative day: week 1 (1–7 days, month 1 (8–41 days, month 2 (42–70 days, month 3 (71–97 days, month 4 (98–126 days, and final (after 127 days. The mean postoperative follow-up was 286.5 days for orbits with at least 6 months of follow-up. Univariate and multivariate linear regression analyses were performed to assess the correlation between the IOP reduction percentage and clinical factors.Results: The mean IOP increased from 16.9 to 18.6 mmHg (10.1% at postoperative week 1 and decreased to 14.4 mmHg (14.5% after 2 months. Minimal little changes were observed postoperatively in the IOP after 2 months. Preoperative IOP had a significant positive effect on the reduction percentage both at postoperative week 1 (β=2.51, P=0.001 and after 2 months (β=1.07, P=0.029, and the spherical equivalent showed a positive correlation with the reduction level at postoperative week 1 (β=1.71, P=0.021.Conclusion: Surgical decompression caused a significant reduction in the IOP in thyroid-associated orbitopathy, and the amount of reduction was closely related to preoperative IOP; however, it may also cause a transient elevation in the IOP during the early postoperative phase in highly myopic eyes.

    Full Text Available Aim of the study. The key point of this research is studying the impact of different methods of medical treatment for patients with dysphonic syndrome after thyroid surgery due to intraoperative injury of the upper laryngeal nerve and complex injury of superior laryngeal nerve as well as the recurrent laryngeal nerve. Materials and methods. The research of various methods of medical treatment was performed on 47 patients after thyroid surgery with dysphonic manifestations. The patients were euthyroid; they were examined at all stages of the treatment by ENT specialist using video laryngoscope. The indices of acoustic voice analysis and evaluation of the voice handicap index, VHI‑30, were determined. The proposed method involves the application of a combination of two pharmacological agents: lysine and choline alfoscerate. At an early postoperative period in case of identifying dysphonic disorders the appropriate medical therapy was prescribed to patients. Identification of the indices of acoustic voice analysis, evaluation of the voice handicap index and fiber laryngoscopy aspect were carried out in groups of patients on the seventh and fourteenth day after the treatment order. Results. All the patients were divided into four groups. Conventional therapy was applied for the patients with diagnosed dysphonic syndrome in the first and the third groups. Patients in the second and the fourth groups received a combined therapy with lysine and cholini alfosceras. The study revealed that in the 2nd and the 4th groups of patients there was a significant change of indices with the trend to almost normal values in comparison with the 1st and the 3rd groups due to increased F0 and ΔF0. It is of great importance that the quality of life has improved, as evidenced by the decrease of VHI‑30. Conclusions. Using a combination of lysine and cholini alfosceras in postoperative dysphonia treatment indicates the effectiveness of this technique as compared to

    Introduction: Transient and persistent hypoparathyroidism (HPT) belong to the well known complications of total thyroidectomy performed because of thyroid carcinoma. The true frequency of persistent hypoparathyroidism is often higher than estimated in the reports published by the specialized centers with low rate of complications. The aim of the study: Investigation whether the repeated check-up, performed over 2 years post thyroidectomy, reveals some cases of recovery in patients diagnosed with persistent HPT post thyroid cancer surgery. Material and methods: In total, 115 patients were included into the study, all of them treated with vitamin D derivatives and calcium supplementation. In 17 of them a diagnosis of transient hypoparathyroidism was made on the basis of evaluation performed 6 months after surgery, the remaining 98 were diagnosed with persistent HPT. Parathyroid (PTH) function was reevaluated after withdrawal of active vitamin D derivatives for 10 days and of calcium carbonate for two days during the hospital stay in patients admitted for radioiodine scan, thus after thyroxine withdrawal. The control group consisted of 123 DTC (differentiated thyroid carcinoma) patients without parathyroid dysfunction. On the basis of intact PTH serum level and calcium and phosphorus estimations HPT was unequivocally confirmed in 49 patients (50%). The remaining 49 patients exhibited normal PTH level and in 43 (86%) of them Ca2+ level was also within normal range, thus delayed, recovery from HPT was stated. Results: Our results indicate that reevaluation of hypoparathyroidism post total thyreoidectomy is necessary, as delayed recover of parathyroid dysfunction is a frequent phenomenon. We also propose criteria of reevaluation of HTP in patients on chronic substitutive therapy. (author)

    Full Text Available Treatment of non-thyroidal illness by intravenous triiodothyronine (T3 after cardiac surgery causes a disproportional elevation of hormone levels. The administration of oral T3, which has never been studied in this context, could cause physiological hormone levels. The aim of this study was to test oral T3 for the prevention of T3 reduction during the postoperative period of valvular cardiac surgery in adults. Eighteen patients who underwent cardiac surgery for valvular disease with invasive hemodynamic monitoring were randomly assigned to 2 groups: the T group received oral T3 (N = 8, 25 µg three times/day, initiated 24 h before surgery and maintained for 48 h and the NT group (N = 10 received placebo. Serum T3, thyroxine and thyrotropin were determined at baseline, 1 h before surgery, within 30 min of cardiopulmonary bypass and 6, 12, 24, and 48 h after removal of the aortic cross-clamp. Baseline T3 was similar in both groups (T: 119 ± 13; NT: 131 ± 9 ng/dL. Serum T3 increased during the first 24 h in the T group compared to the NT group (232 ± 18 vs 151 ± 13 ng/dL; P < 0.001. In the NT group, T3 was reduced by 24% (P = 0.007 6 h after removal of the aortic cross-clamp, confirming the non-thyroidal illness syndrome. There were no differences in clinical or hemodynamic parameters between groups. Administration of oral T3 prevented its serum reduction after valvular cardiac surgery in adults, with normal serum levels for 48 h without disproportional elevations.

    We have examined if there are any differences in intraoperative and early postoperative concentrations of parathyroid hormone between the first group of patients, who had thyroidectomy surgery performed by harmonic scalpel, and the second group of patients operated on by standard techniqes with the use of electrocoagulation and ligature as primary hemostatic procedures. All the patients having total thyroidectomy had their blood taken in four measurement points; immediately after the induction anesthesia, 10 minutes after the first thyroid gland lobe removal, 10 minutes after total thyroid gland removal and 24 hours after the surgery. The blood samples were used to determine concentrations of the parathyroid hormone by an immunoradiometric test. The concentration comparison of parathyroid hormone between the first and the second group has not shown statistically significant difference for any of the four measurement points. The concentration comparison of parathyroid hormone within the same groups in relation to preoperational values (the first measurement point) has shown that in both groups the parathyroid hormone concentration, in all three post-incision measurement points, has been significantly lower in relation to the concentration measured before the surgery (p < 0.0005).

    The diagnosis and treatment of thyroid disease has significantly changed with time. With the aim of analysing changes in thyroid surgery in our institution, a representative sample of patients from the first three years in four decades (1960-1992) were comparatively analysed. In the sixties, the diagnosis of thyroid cancer was made during surgery; by contrast, this diagnosis was correctly done by fine needle aspiration (FNA) in most patients of the last decade. Thyroid lobectomy, infrequently used in the treatment of differentiated thyroid carcinoma in earlier times, has now been abandoned and currently most patients undergo total or near-total thyroidectomy. Complications such as hypoparathyroidism and recurrent laryngeal nerve paralysis have importantly decreased with time and were not seen in the last decade. A trend toward an earlier diagnosis of thyroid carcinoma was also observed. In summary, the number of thyroidectomies for benign diseases has been importantly reduced by the use of FNA with the proportional increment of surgery for malignant disease.

    Objective We aim to evaluate the technique of identifying parathyroid glands with carbon nanoparticle suspension (CNPS) in thyroid surgeries from the perspectives of degrees of declining intact parathyroid hormone (iPTH), operation time, and time of postoperative stay. Methods A total of 156 patients who underwent thyroid surgeries in General Surgical Department of Xiangya Hospital between May 2012 and May 2015 were involved in the study. A total of 78 patients were injected with CNPS during the surgery (CNPS group); the other 78 patients received normal saline (control group). Cases were classified into 3 surgical approaches: conventional partial thyroidectomy, conventional total thyroidectomy, and endoscopic partial thyroidectomy. Degrees of declining iPTH were tested to determine the severity of parathyroid injury. Operation time and postoperative hospital stay time were recorded. A P value of less than .05 was considered statistically significant. Results For levels of declining iPTH, there was no statistically significant (ss) difference in conventional thyroid surgery. In endoscopic partial thyroidectomy, it was 23.37 ± 16.20 versus 11.94 ± 11.23 pg/mL (P = .02, ss). The operation time of conventional total thyroidectomy was 210.10 ± 83.75 versus 164.84 ± 69.22 minutes (P = .03, ss), while it was 193.04 ± 75.53 versus 127.67 ± 60.06 minutes (P = .007, ss) in endoscopic thyroidectomy. Conclusions CNPS is not beneficial for protecting the function of parathyroid gland in thyroid surgery from the perspective of declining iPTH. Applying CNPS in conventional total thyroidectomy and endoscopic partial thyroidectomy will also lead to significantly prolonged operation time. © The Author(s) 2016.

  5. Long-Term Results after Treatment of Very Low-, Low-, and High-Risk Thyroid Cancers in a Combined Setting of Thyroidectomy and Radio Ablation Therapy in Euthyroidism

    Full Text Available Introduction. Differentiated thyroid cancer treatment usually consists of thyroidectomy and radio ablation in hypothyroidism 4-6 weeks after surgery. Replacing hypothyroidism by recombinant human thyroid stimulating hormone can facilitate radio ablation in euthyroidism within one week after surgery. The outcome of this approach was investigated. Methods. This is a prospective randomized trial to compare thyroidectomy and radio ablation within a few days after preconditioning with recombinant human thyroid stimulating hormone versus thyroidectomy and radio ablation separated by four weeks of L-T4 withdrawal. Tumors were graded into very low-, low- , or high-risk tumors. Recurrence-free survival was confirmed at follow-up controls by neck ultrasound and serum thyroglobulin. Suspected tumor recurrence was treated by additional radio ablation or surgery. Quality-of-life questionnaires with additional evaluation of job performance and sick-leave time were used in all patients. Results. Radio ablation in euthyroidism in quick succession after thyroidectomy did not lead to higher tumor recurrence rates of differentiated thyroid cancers in any risk category and was significantly advantageous with respect to quality-of-life (P<0.001, sick-leave time (P<0.001, and job performance (P=0.002. Conclusion. Recombinant human thyroid stimulating hormone can be used safely and with good efficacy to allow radio ablation under sustained euthyroidism within one week after thyroidectomy.

    A male patient with papillary thyroid cancer -follicular variety- is chosen to be presented. After thyroidectomy, lymphadenectomy and therapeutic dose of radioiodine treatments, cancer relapse was observed. After thyrotrophin suppressive therapy with l-thyroxine, a high serum thyroglobulin concentration was observed. The Ultrasonography (US) and Magnetic Resonance (MR) images showed visible node structures in the neck. This node structures were probably going to concentrate I-131 as seen in the fi rst whole body scan after therapeutic dose. Therefore a radio-guided surgery was planned as the best choice. (Institute Gustave Roussy protocol). A therapeutic dose of radioiodine (I-131) was given and up to the 4th day a whole body scan was performed. In the 5th day a gamma- probe-guided surgery was performed as well, and localized metastatic foci in the pretracheal region and under right recurrent laryngeal nerve. No other foci were identified ed with the probe at surgery. Forty eight hours after surgery a new whole-body scan was made again. The procedure was successful. The metastatic lesions were completely dissected. The last whole body scan showed that radioiodine concentration had disappeared at all. Forty fi ve days and three months after surgery under levothyroxine treatment, the serum thyroglobulin level concentration decrease to very low values. (authors) [es

    The incidence of thyroid cancer is increasing rapidly in many countries, resulting in rising societal costs of the care of thyroid cancer. We reported that the active surveillance of low-risk papillary microcarcinoma had less unfavorable events than immediate surgery, while the oncological outcomes of these managements were similarly excellent. Here we calculated the medical costs of these two managements. We created a model of the flow of these managements, based on our previous study. The flow and costs include the step of diagnosis, surgery, prescription of medicine, recurrence, salvage surgery for recurrence, and care for 10 years after the diagnosis. The costs were calculated according to the typical clinical practices at Kuma Hospital performed under the Japanese Health Care Insurance System. If conversion surgeries were not considered, the 'simple cost' of active surveillance for 10 years was 167,780 yen/patient. If there were no recurrences, the 'simple cost' of immediate surgery was calculated as 794,770 yen/patient to 1,086,070 yen/patient, depending on the type of surgery and postoperative medication. The 'simple cost' of surgery was 4.7 to 6.5 times the 'simple cost' of surveillance. When conversion surgeries and recurrence were considered, the 'total cost' of active surveillance for 10 years became 225,695 yen/patient. When recurrence were considered, the 'total cost' of immediate surgery was 928,094 yen/patient, which was 4.1 times the 'total cost' of the active surveillance. At Kuma Hospital in Japan, the 10-year total cost of immediate surgery was 4.1 times expensive than active surveillance.

    The aim of this study was to evaluate the efficacy of carbon nanoparticles in identifying lymph nodes and promoting parathyroid gland function recovery after thyroid carcinoma surgery along with central lymph node dissection. A total of 231 patients who underwent thyroid carcinoma surgery combined with central lymph node dissection were divided into two groups: the CN group (intraoperative carbon nanoparticles injections) and the control group (no injection). Datas were collected respectively on the pre-operative, 1st, 7th and 30th postoperative days and monthly thereafter. While the pathological results (e.g. amount of incidental removed parathyroid glands and lymph nodes dissected), complications (e.g. rates of vocal cord paralysis, the neuromuscular symptoms, hypocalcemia and hypoparathyroidism), as well as follow-up outcomes of the serum Ca2+ and PTH levels were gathered and measured to be included in. In regard to the results of the pathological tests, the control group had a relatively higher incidence of incidental parathyroidectomy when compared to the CN group (P  0.05). Carbon nanoparticles play a key role in accurately identifying lymph nodes, reducing mistaken excision of parathyroid glands, accelerating rapid recovery of parathyroid function during thyroid carcinoma surgery with central lymph node dissection, without increasing the probability of postoperative complications.

    Minimal access thyroidectomy, using various techniques, is widely known, but respective data on thyroidectomy for thyroid cancer with lymphadenectomy is scarce. The present study aims to evaluate the feasability of extended subplatysmal dissection in combination with a small incision ("mobile window" technique). A retrospective study was performed analysing data from 93 patients. All patients suffered from thyroid carcinoma and underwent (total) thyroidectomy, bilateral cervico-central (levels VI and VII) and functional lateral neck dissection (levels II to V) on the side of the malignancy. In group A, consisting of 47 patients, the operation was performed by a traditional Kocher incision (minimal range 6-7 cm), in 46 patients (group B) a mini-incision (≤4 cm) was made. Intra- and postoperative morbidity as well as oncological accuracy were assessed. There was no significant difference between the two groups comparing postoperative pathological diagnosis, intra- and postoperative complications and the number of removed lymph nodes. However, operating time was slightly longer in group A and thyroid weight was heavier in group B. Extended subplatymsal dissection allows thyroidectomy and even lateral lymphadenectomy for thyroid carcinoma via "mobile" mini-incision. The procedure is safe, of equivalent oncological accuracy compared to traditional incision and the cosmetic results are excellent.

    Actually, thyroid volume >25 ml, obtained by preoperative ultrasound evaluation, is a very important exclusion criteria for minimally invasive thyroidectomy. So far, among different imaging techniques, two-dimensional ultrasonography has become the more accepted method for the assessment of thyroid volume (US-TV). The aims of this study were: (1) to estimate the preoperative thyroid volume in patients undergoing minimally invasive total thyroidectomy using a mathematical formula and (2) to verify its validity by comparing it with the postsurgical TV (PS-TV). In 53 patients who underwent minimally invasive total thyroidectomy (from January 2003 to December 2007), US-TV, obtained by ellipsoid volume formula, was compared to PS-TV determined by the Archimedes' principle. A mathematical formula able to predict the TV from the US-TV was applied in 34 cases in the last 2 years. Mean US-TV (14.4 +/- 5.9 ml) was significantly lower than mean PS-TV (21.7 +/- 10.3 ml). This underestimation was related to gland multinodularity and/or nodular involvement of the isthmus. A mathematical formula to reduce US-TV underestimation and predict the real TV was developed using a linear model. Mean predicted TV (16.8 +/- 3.7 ml) perfectly matched mean PS-TV, underestimating PS-TV in 19% of cases. We verified the accuracy of this mathematical model in patients' eligibility for minimally invasive total thyroidectomy, and we demonstrated that a predicted TV <25 ml was confirmed post-surgery in 94% of cases. We demonstrated that using a linear model, it is possible to predict from US the PS-TV with high accuracy. In fact, the mean predicted TV perfectly matched the mean PS-TV in all cases. In particular, the percentage of cases in which the predicted TV perfectly matched the PS-TV increases from 23%, estimated by US, to 43%. Moreover, the percentage of TV underestimation was reduced from 77% to 19%, as well as the range of the disagreement from up to 200% to 80%. This study shows that two

    A substantial increase of childhood cancer cases observed in Belarus, Ukraine and Russia after the Chernobyl accident has been associated with thyroid exposure to radio iodines following the accident. A large number of direct thyroid measurements (i.e. measurement of the exposure rate near the thyroid of the subject)were conducted in Belarus during a few weeks after the accident. Individual thyroid doses based on results of the direct thyroid measurements were estimated for about 126,000 Belarusian residents and settlement-average thyroid doses for adults were calculated for 426 contaminated settlements in Gomel and Mogilev Oblasts. Another set of settlement-average thyroid doses for adults was estimated based on results of activity measurements in milk samples for 28 settlements (with not less than 2 spectrometric measurements) and 155 settlements (with not less than 5 total beta-activity measurements) in Gomel and Mogilev Oblasts. Concentrations of 131 I in milk were derived from these measurements. In the estimation of this set of thyroid doses, it was assumed that adults consumed 0.5 L d -1 of milk locally produced. The two sets of dose estimates were compared for 47 settlements, for which simultaneously were available a dose estimate based on thyroid measurements and a dose estimate based either on spectrometric or radiometric milk data. The settlement average thyroid doses based on milk activity measurements were higher than those based on direct thyroid measurements by a factor of 1.8 for total beta-activity measurements (30 settlements were compared) and by a factor of 2.4 for spectrometric measurements (17 settlements). This systematic difference can be explained by overestimation of the milk consumption rate used in the calculation of the milk-based thyroid doses and/or by application of individual countermeasures by people.

    The aim of this study was to determine the effects of nanocarbon particles in combination with meticulous capsular dissection on enhancing the identification and protecting the function of parathyroid glands in thyroid cancer surgery.The data of 97 patients with papillary thyroid tumors diagnosed and treated at the Second Affiliated Hospital, Harbin Medical University between January 2014 and February 2015 were reviewed. Data regarding the sex, age, calcium and parathyroid hormone (PTH) levels, tumor size, multifocality, T stage, and extrathyroid invasion were collected. The incidence of surgeries in which the parathyroid glands were cut mistakenly, the concentration of serum calcium and parathyroid hormone before surgery (baseline) and after surgery on days 1, 3, and 7, and 1 and 6 months in the patients of the two groups (the nanocarbon and control groups) were analyzed.Fifty-two patients underwent meticulous capsular dissection combined with nanocarbon treatment (nanocarbon group), and 45 underwent meticulous capsular dissection alone (control group). The nanocarbon group showed a significantly higher total and average number of revealed parathyroid glands (average number is the mean for different individuals have different number) and a lower incidence of the parathyroid glands being mistakenly cut, in addition to a lower level of hypoparathyroidism than control group following surgery (P parathyroid in thyroid cancer surgery, reduce the risk of mistakenly cutting the parathyroid, and reduce the incidence of postoperative hypoparathyroidism.

    To explore the feasibility and safety of transtracheal assisted sublingual approach to totally endoscopic thyroidectomy by studying the anatomical approach and adjacent structures. A total of 5 embalmed adult cadavers from Chengdu Medical College were dissected layer by layer in the cervical region, pharyngeal region, and mandible region, according to transtracheal assisted sublingual approach that was verified from the anatomical approach and planes. A total of 15 embalmed adult cadavers were dissected by arterial vascular casting technique, imaging scanning technique, and thin layer cryotomy. Then the vessel and anatomical structures of thyroid surgical region were analyzed qualitatively and quantitatively. Three-dimensional visualization of larynx artery was reconstructed by Autodesk 3ds Max 2010(32). Transtracheal assisted sublingual approach for totally endoscopic thyroidectomy was simulated on 5 embalmed adult cadavers. The sublingual observed access was located in the middle of sublingual region. The geniohyoid muscle, mylohyoid seam, and submental triangle were divided in turn in the middle to reach the plane under the plastima muscles. Superficial cervical fascia, anterior body of hyoid bone, and infrahyoid muscles were passed in sequence to reach thyroid gland surgical region. The transtracheal operational access was placed from the cavitas oris propria, isthmus faucium, subepiglottic region, laryngeal pharynx, and intermediate laryngeal cavit, and then passed from the top down in order to reach pars cervicalis tracheae where a sagittal incision was made in the anterior wall of cartilagines tracheales to reach a ascertained surgical region. Transtracheal assisted sublingual approach to totally endoscopic thyroidectomy is anatomically feasible and safe and can be useful in thyroid gland surgery.

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

    The purpose of this study was to evaluate the probability of death for patients with thyroid cancer and construct a comprehensive nomogram based on a competing risks model to predict cumulative incidence of death resulting from thyroid cancer, other cancers, and non-cancer-related causes. Patients diagnosed with thyroid cancer between 1988 and 2003 were selected for the study from the Surveillance, Epidemiology, and End Results program. We estimated probabilities of death resulting from thyroid cancer, other cancers, and noncancer causes and analyzed associations of patient and tumor characteristics with probability of death. A nomogram for predicting probability of death was built using a proportional subdistribution hazard competing risks model. The entire cohort comprised 29,225 patients with malignant thyroid cancer. Median duration of follow-up until censoring or death was 85 months (range, 0 to 239 months). Five-year probabilities of death resulting from thyroid cancer, other cancer, and noncancer causes were 1.9%, 0.8%, and 1.7%, respectively. Increasing age and tumor size, male sex, poorly differentiated carcinoma, lymph node involvement, and regional and metastatic disease were associated with increased cumulative incidence of death resulting from thyroid cancer. A nomogram based on a competing risks model was developed for predicting the probability of death for patients with thyroid cancer. Performance of the model was excellent. This nomogram may be useful for patients and clinicians when predictions are needed.

    To analyze the effect of long-term thyroid-stimulating hormone (TSH) suppressive therapy on the gonadal hormones and related symptoms in patients after surgery. From 2008 to 2011, totally 238 patients were recruited, who underwent thyroid surgery and subsequent TSH suppression treatment in Department of thyroid Surgery, China-Japan Union hospital, Jilin University. Then their postoperative follow-up data (3-8 years) were collected, including operational method, pathological diagnosis, whether processed radioiodine therapy and the period/dose of TSH suppression treatment. In addition, the menstrual cycle, menstruation quantity, whether accompanied with dysmenorrheal and menstrual disorder or not, date of last menstrual period, ages of menopause and so on were also collected. (I) Neither the level nor the duration of TSH treatment had any function on estradiol (E2) and testosterone (T) in male patients; (II) in the subgroup of patients with TSH treatment for 3-5 years, patients who took high dose of TSH (TSH ≥0.5 U/L) obtained the lower T level compared with the group of medium dose (1.08±0.34 vs. 1.36±0.46 nmol/L, P=0.001); (III) in the medium dose (0.1 IU/L ≤ TSH hormone (FSH) did not show any change in terms of the dose and the duration of TSH treatment; (V) the menstrual volume, dysmenorrhea condition, menstrual cycle and menopause related indicators did not show any difference in terms of doses and duration of TSH treatment (P=0.701, 0.412 and 0.507 respectively). The long term of TSH repressive therapy after surgery did not affect T and E2 level in male patients. As for female patients, the impact was mainly reflected in the T and E2 levels especially in female sexual maturity but not FSH level. In addition, TSH treatment did not play any role on menstruation or menopause.

    BACKGROUND: Findings from the few epidemiological studies that have investigated thyroid cancer risk after fertility drugs have been inconclusive. Using data from the largest cohort of infertile women to date, we examined the effects of fertility drugs on thyroid cancer risk. METHODS: A cohort...... of 54 362 women with infertility problems referred to Danish fertility clinics in the period 1963-1998 was established. A detailed data collection including information about type and amount of treatment was conducted. Using case-cohort techniques, we calculated rate ratios (RRs) of thyroid cancer...... associated with different fertility drugs after adjustment for age at first live birth. RESULTS: A total of 29 thyroid cancers were identified during follow-up through 2000. Use of clomiphene [RR = 2.28; 95% confidence interval (CI): 1.08-4.82] or progesterone (RR = 10.14; 95% CI: 1.93-53.33) was associated...

    Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. To develop a support document for guidance on the use of IONM in TPTS. Work group consensus through systematic review and the Delphi method. Seven sections were identified on which points of consensus were identified: indications, equipment, technique (programming and registration parameters), behaviour on loss of signal, laryngoscopy, voice and legal implications. IONM helps in the location and identification of the recurrent laryngeal nerve, helps during its dissection, reports on its functional status at the end of surgery and enables decision-making in the event of loss of signal in the first operated side in a scheduled bilateral thyroidectomy or previous contralateral paralysis. The accuracy of IONM depends on variables such as accomplished technique, technology and training in the correct execution of the technique and interpretation of the signal. This document is a starting point for future agreements on TPTS in each of the sections of consensus.

Methods: English and Chinese literature in PubMed, Cochrane Database of Systematic Reviews, EMBASE, ClinicalTrials.gov, China Biology Medicine Database, China National Knowledge Infrastructure, China Master’s and Doctoral Theses Full-Text Database, Wanfang database, and Cqvip database were searched (till March 22, 2016. Randomized controlled trials (RCTs that compared the use of CNs with a blank control in patients undergoing thyroid cancer surgery were included. Quality assessment and data extraction were performed, and a meta-analysis was conducted using RevMan 5.1 software. The primary outcomes were the number of retrieved central lymph nodes and metastatic lymph nodes, and the rate of accidental parathyroid removal. Results: We obtained 149 relevant studies, and only 47 RCTs with 4,605 patients (CN group: n=2,197; blank control group: n=2,408 met the inclusion criteria. Compared with the control group, the CN group was associated with more retrieved lymph nodes/patient (weighted mean difference [WMD]: 3.39, 95% confidence interval [CI]: 2.73–4.05, more retrieved metastatic lymph nodes (WMD: 0.98, 95% CI: 0.61–1.35, lower rate of accidental parathyroid removal, and lower rates of hypoparathyroidism and hypocalcemia. However, the total metastatic rate of the retrieved lymph nodes did not differ between the groups (odds ratio: 1.13, 95% CI: 0.87–1.47, P=0.35. Conclusion: CNs can improve the extent of neck dissection and protect the parathyroid glands during thyroid cancer surgery. And the number of identified metastatic lymph nodes can be simultaneously increased

    2007-01-01

    Relapse rates of surgically treated clubfeet are about 25%. We reviewed 43 patients (57 feet) treated for relapsed clubfoot deformity between 1992 and 2001 in our department. The average age of the patients at the time of revision surgery was 5.1 years, the mean follow-up was 6.6 years. Surgical therapy was performed using an algorithm according to age groups. The mean Atar score at follow-up was 77 points, representing a good outcome. Out of 57 feet, 20 (35%) were rated excellent, 24 (42%) good, 5 (9%) fair, and 8 (14%) poor. The number of previous surgical interventions had no influence on the outcome. Using an age related surgical algorithm, good postoperative results could be achieved in most of our patients, thus improving their functional situation. This emphasises the usefulness of the proposed algorithm in the difficult situation of recurrent clubfoot, while thorough analysis of the underlying deformity remains essential. PMID:18094969

    There are several classifications based on thyroid ultrasound for selecting suspected malignant thyroid nodules. The Thyroid Imaging Reporting and Data System (TI-RADS) classification proposed by Horvath in 2009 includes 6 categories. To assess the sensitivity of the TI-RADS classification for diagnosing thyroid nodules. A retrospective study of all patients who underwent thyroidectomy at our hospital (n=263) from September 2013 to December 2015. After thyroidectomy, histological results were correlated to the ultrasound findings reported. Of the 263 study patients, 75 (28.5%) were diagnosed with thyroid cancer and 188 (71.5%) with benign disease. Correlation of histological results with preoperative ultrasound reports showed an initial sensitivity of 65%. After excluding 15 patients diagnosed with occult microcarcinoma, sensitivity increased to 81.6%. The ultrasound images from 11 false negatives cases were then reassessed by a radiologist who knew histological diagnosis and reclassified 10 of them as TI-RADS≥4. This procedure could have increased sensitivity up to 98.3%. Although the sensitivity initially found in our study using the TI-RADS scale was relatively low, the value markedly improved when patients with occult microcarcinoma were excluded. Thus, use of the TI-RADS scale would allow for an adequate selection of patients amenable to fine needle aspiration of the nodule. Copyright © 2018 SEEN y SED. Publicado por Elsevier España, S.L.U.

    Postoperative hypoparathyroidism remains the most common complication following thyroidectomy. The aim of this pilot study was to evaluate the use of intraoperative parathyroid gland angiography in predicting normal parathyroid gland function after thyroid surgery. Angiography with the fluorescent dye indocyanine green (ICG) was performed in patients undergoing total thyroidectomy, to visualize vascularization of identified parathyroid glands. Some 36 patients underwent ICG angiography during thyroidectomy. All patients received standard calcium and vitamin D supplementation. At least one well vascularized parathyroid gland was demonstrated by ICG angiography in 30 patients. All 30 patients had parathyroid hormone (PTH) levels in the normal range on postoperative day (POD) 1 and 10, and only one patient exhibited asymptomatic hypocalcaemia on POD 1. Mean(s.d.) PTH and calcium levels in these patients were 3·3(1·4) pmol/l and 2·27(0·10) mmol/l respectively on POD 1, and 4·0(1.6) pmol/l and 2·32(0·08) mmol/l on POD 10. Two of the six patients in whom no well vascularized parathyroid gland could be demonstrated developed transient hypoparathyroidism. None of the 36 patients presented symptomatic hypocalcaemia, and none received treatment for hypoparathyroidism. PTH levels on POD 1 were normal in all patients who had at least one well vascularized parathyroid gland demonstrated during surgery by ICG angiography, and none required treatment for hypoparathyroidism. © 2016 The Authors.

    "Taking less treating better" has been one of the major improvements of breast cancer surgery in the last four decades. The application of this principle translates into equivalent survival of breast cancer conserving treatment (BCT) when compared to mastectomy, with a better cosmetic outcome. While it is relatively easy to evaluate the oncological results of BCT, the cosmetic outcome is more difficult to measure due to the lack of an effective and consensual procedure. The assessment of cosmetic outcome has been mainly subjective, undertaken by a panel of expert observers or/and by patient self-assessment. Unfortunately, the reproducibility of these methods is low. Objective methods have higher values of reproducibility but still lack the inclusion of several features considered by specialists in BCT to be fundamental for cosmetic outcome. The recent addition of volume information obtained with 3D images seems promising. Until now, unfortunately, no method is considered to be the standard of care. This paper revises the history of cosmetic evaluation and guides us into the future aiming at a method that can easily be used and accepted by all, caregivers and caretakers, allowing not only the comparison of results but the improvement of performance. © 2014 Wiley Periodicals, Inc.

They had undergone lobectomy with isthmusectomy. This is a retrospective cohort study in which the oncological outcome (contralateral and regional recurrence and the reoperation complications (recurrent nerve paralysis/paresis and hypoparathyroidism were evaluated. Descriptive analysis was employed.RESULTS: In the last decade (2003-2013, 6 (20% contralateral recurrences were observed in the remaining lobe and in 1 of these cases (3%, contralateral lymph node metastases were noted. A completion thyroidectomy plus lymphadenectomy was performed, without modification of global survival.CONCLUSION: Because of the rate of 20% of contralateral recurrence after a 20-year follow-up, we suggest modification of the surgical paradigm for total thyroidectomy as an initial therapy.

    2016-03-01

    Full Text Available Introduction: Patient safety is defined as the reduction of risk of unnecessary harm associated with healthcare. Up to 9.3% of patients admitted into a hospital present some adverse event related to the assistance. This can cause damage to the patient, more instrumentation, increased morbidity, increased hospital stay and increased cost. To identify, record and analyze adverse events is necessary to have an incident reporting system. Objective: Developing a local system for reporting security incidents and adverse events in surgery of the thyroid gland. Method: A working group was formed with representatives from all units related to the process of thyroidectomy, checkpoints were established, checklists for each control point were designed, a strategic analysis of the group's activity was performed, a literature review was done in order to identify the major incident reporting systems, the items that the incident report form must have were identified and the form was designed. Results: The incident report form collects data on the patient, the communicator and the incident (type, cause, consequence, severity, frequency, risk matrix. It has a first paragraph with narrative sections and a second with drop-down lists. The form is accessible only to the working group for voluntary use. Conclusions: The purpose of the reporting system is learning and prevention.

    Objective To identify and save parathyroid glands during thyroidectomy by displaying their autofluorescence. Methods Autofluorescence imaging was carried out during thyroidectomy with and without central lymph node dissection. After visual recognition by the surgeon, the parathyroid glands and the surrounding tissue were exposed to near-infrared light with a wavelength of 690-770 nm using a modified Karl Storz near infrared/indocyanine green endoscopic system. Parathyroid tissue was expected to show near infrared autofluorescence at 820 nm, captured in the blue channel of the camera. Results We investigated 41 parathyroid glands from 20 patients; 37 glands were identified correctly based on near-infrared autofluorescence. Neither lymph nodes nor thyroid revealed substantial autofluorescence and nor did adipose tissue. Conclusions Parathyroid tissue is characterised by showing autofluorescence in the near-infrared spectrum. This effect can be used to identify and preserve parathyroid glands during thyroidectomy.

    Purpose To compare the cytological results of ultrasound-guided fine-needle aspiration (US-FNA) cytology of thyroid nodules to sonographic findings and determine whether US findings are helpful in the interpretation of cytological results. Materials and Methods Among the thyroid nodules that underwent US-FNA cytology, we included the 819 nodules which had a conclusive diagnosis. Final diagnosis was based on pathology from surgery, repeated FNA cytology or follow-up of more than one year. Cytological results were divided into five groups: benign, indeterminate (follicular or Hurthle cell neoplasm), suspicious for malignancy, malignant, and inadequate. US findings were categorized as benign or suspicious. Cytological results and US categories were analyzed. Results Final diagnosis was concluded upon in 819 nodules based on pathology (n=311), repeated FNA cytology (n=204) and follow-up (n=304), of which 634 were benign and 185 were malignant. There were 560 benign nodules, 141 malignant nodules, 49 nodules with inadequate results, 21 with indeterminate results, and 48 that were suspicious for malignancy. The positive and negative predictive values of the US categories were 59.1% and 97.0%, and those of the cytological results were 93.7% and 98.9%. The US categories were significantly correlated with final diagnosis in the benign (p=0.014) and suspicious for malignancy (pcytological result groups, but not in the inadequate and indeterminate cytological results groups. The false positive and negative rates of cytological results were 1.9% and 3.2%. Conclusion Sonographic findings can be useful when used alongside cytological results, especially in nodules with cytological results that are benign or suspicious for malignancy. PMID:21786450

    Full Text Available Cancer is a disorder of the genome. The thyroid cancer genome is being decoded. Recent studies have identified a mutation or a genetic alteration in 95% of thyroid cancers. The National Cancer Institute initiated the Cancer Genome Atlas project in 2006 to catalogue genetic mutations associated with cancer, using genome sequencing and bioinformatics. The project has expanded to carry out genomic characterization and sequence analysis of thyroid cancer. The concept of risk stratification based on traditional parameters will soon vacate their role for clear molecular markers of non-invasive/focal, invasive/metastatic and systemic stages/phases of neoplastic disorder. A refined classification scheme based on genomics and its phenotypic expressions will accurately reflect the biologic differences between the different morphologic definitions we use today. Tumor differentiation/de-differentiation, and clinical behavior of an individual cancer will be defined by molecular markers, in addition to standard morpho-pathology. Empiricism in science of medicine and surgery has acquired a new method for testing the appropriate treatment for individual patients; that is molecular pathology, governed by genomics. The technology is present and rapidly evolving. The surgeons will determine the extent of interventions with molecular evidence and guidance.

Group 1 included 102 patients (118 eyes), who were considered surgical candidates due to decompensation of IOP, group 2--70 patients (75 eyes), in whom IOP control could only be achieved with a multidrug regimen (two or more ocular hypotensive medications). The mean preoperative IOP measured with Maklakov tonometer was 26.4 ± 1.8 mmHg in group 1 and 20.5 ± 1.7 mmHg in group 2. In 134 eyes the extent of retention of intraocular fluid was determined intraoperatively by provoking blood reflux into Schlemm's canal. In 6 out of 134 eyes (4.5%) Schlemm's canal was not at all filled with blood, which was considered a contraindication for endotrabeculectomy. Partial filling of Schlemm's canal with blood was observed in 26 out of 134 eyes (19.4%), complete--in 102 eyes (76.1%). All but 6 patients underwent endotrabeculectomy (ab interno trabecular excision with original forceps through the anterior chamber angle) combined with cataract phacoemulsification and intraocular lens implantation. In 11 out of 126 cases, insignificant bleeding occurred during sample acquisition. No other complications were registered. Six months after the surgery, IOP was reduced by the mean of 7.0 ± 0.6 mmHg (26.5% from the baseline) in group 1 and by 2.2 ± 0.2 mmHg (10.7% from the baseline) in group 2. The number of hypotensive medications by that time has been decreased from 2.3 ± 0.3 to 0.8 ± 0.2 in group 1 and from 1.6 ± 0.3 to 0.4 ± 0.1 in group 2. Combined endotrabeculectomy and phacoemulsification surgery is a pathogenically oriented procedure, which improves ocular hydrodynamics and has a significant hypotensive effect.

    Introduction: Thyroid cancer is the most common endocrine malignancy. The current gold standard for diagnosis, fine-needle aspiration (FNA) biopsy, yields 10-25% of indeterminate cytology results, leading to patients undergoing thyroidectomy for diagnosis. We assessed the technical potential of a miniaturized in vivo ESS (elastic light scattering spectroscopy) probe, built into an FNA needle assembly, to differentiate benign from malignant thyroid nodules. Methods: Under IRB approval, 15 patients in the endocrine clinic undergoing FNAB of a thyroid nodule had collection of ESS data using our novel miniaturized FNA probe. Using final surgical pathology as our gold standard, data post processing and visual inspection was completed. Results: 225 spectra were grouped and analyzed (120 benign, 30 malignant and 75 from indeterminate cytology). ESS probes demonstrated excellent reproducibility in use. Initial analysis of these preliminary data is promising, indicating distinction of spectral ESS features between malignant and benign conditions. Conclusion(s): An in vivo trial of an invasive miniaturized integrated ESS biopsy probe is acceptable to patients, and collection of ESS data is feasible and reliable. With development of a disease-specific algorithm, ESS could potentially be used as an in-situ real time intra-operative diagnostic tool or as a minimally invasive adjunct to conventional FNA cytology.

    To report the outcomes in patients undergoing surgical correction of intermittent exotropia and to compare the age at surgery to motor and sensory success. This was a retrospective cohort study. The results of patients with intermittent exotropia treated with surgery over a 4-year period were reviewed. Patients were divided into two groups based on age at first surgery (groups. One hundred thirty-six patients were evaluated, with 67 and 51 patients undergoing surgery before and after the age of 4 years, respectively. The mean age at surgery was 6.8 ± 2.6 years. The reoperation rate for the patients who underwent surgery before 4 years of age was 48% versus 42% for the ones who underwent surgery after this age (p=0.93). Postoperative stereopsis showed an inverse linear association with age at surgery (page, and may even present better motor results than older patients. Postoperative stereoacuity in younger children revealed to be worse than in older children; however, this result is unlikely to be due to inadequate age for surgery, but rather, immaturity for performing the stereopsis test.

    The Multicentre Study Differentiated Thyroid Cancer (MSDS) collective represents a well defined group of patients with locally aggressive thyroid carcinomas (pT4; AJCC/UICC 1997). The aim of the present study was to compare the survival of patients with minimum and extensive extrathyroidal growth according to the new AJCC/UICC TNM staging system 2009. Patients, methods: The follow-up data of 347 patients were analysed. Patients were reclassified according to the current AJCC/UICC 2009 classification. The event-free and overall survival was evaluated using Kaplan-Meier analysis. In addition, postoperative complications and status of disease were documented. Results: 327 patients were assigned to stage pT3 and 20 patients to stage pT4a, respectively. Median follow-up was 6.1 years (range 0.04-9.8 years). 92.5% of patients reached complete remission. There were 7.8% recurrences in the thyroid bed, in locoregional lymph nodes and/or in distant sites. The overall survival was >98% both in pT3 and pT4a patients (p = n. s.). In contrast, the event-free survival was significantly less favourable in pT4a patients (p < 0.001). Using multivariate analysis the following parameters were significant predictors of event-free survival: histological tumour type, degree of extrathyroidal extension and nodal metastasis (p < 0.05). Conclusions: The MSDS patients with locally aggressive differentiated thyroid cancer showed an excellent overall survival during a median follow-up of 6.1 years. According to the current AJCC/UICC 2009 classification, pT3 patients with minimal extrathyroidal extension revealed a significantly better event-free survival than pT4a patients with extensive extrathyroidal growth.

    Within weeks of the Chernobyl accident, about 300000 measurements of human thyroidal 131 I content were conducted in the more contaminated territories of the Republic of Belarus. Results of these and other measurements form the basis of thyroid-dose reconstruction for residents of Belarus. Preliminary estimates of thyroid doses have been divided into three classes. Class 1 ('measured' doses). Individual doses are estimated directly from the measured thyroidal 131 I content of the person considered, plus information on life style and dietary habits. Such estimates are available for about 130000 individuals from the contaminated areas of Gomel and Mogilev Region and Minsk city. Class 2 ('passport' doses). For every settlement with a sufficient number of residents with 'measured' doses, individual thyroid-dose distributions are determined for several age groups and levels of milk consumption. This action has been called the 'passportization' of the settlement. A population of about 2.7 million people resides in the 'passportized' settlements. Class 3 ('inferred' doses). For any settlement where the number of residents with 'measured' doses is small or equal to zero, individual thyroid doses are derived from the relationship obtained between the mean adult-thyroid dose and the deposition density of 131 I or 137 Cs in settlements with 'passport' doses presenting characteristics similar to those of the settlement considered. This method can be applied to the remainder of the population (about 7.3 million people). An approximate estimate of the collective thyroid dose for the residents of Belarus is presented. Illustrative results of individual thyroid dose and associated uncertainty are discussed for rural settlements and urban areas

    In order to evaluate the efficacy of, and the risk associated with, the definite treatment of euthyroid goiter with autonomy, the data of 88 patients treated between 1982 and 1986 (50 by subtotal thyroidectomy; 38 by 131 I-treatment, mean radiation dose 200 Gy without protection by thyroxine) were analyzed in a retrospective study. The following criteria were used before and after treatment: the results of scintigraphy under suppression qualitatively (in focal autonomy) and quantitatively (global thyroid uptake) (TcU s ), the means of FT 4 I, FT 3 I and ΔTSH after TRH, the improvement of mechanical signs and symptoms and the decrease of thyroid volume. Measured by TcU s and ΔTSH, autonomy could be removed completely in 85-90% of all patients. Surgery was slightly more successful (100%) compared to treatment by 131 I (75-80%). This was also true for removal of mechanical symptoms and reduction of the goiter. The incidence of manifest hypothyroidism was greater after surgery (16%) than after 131 I treatment (3%). At a higher grade of autonomy (TcU s > 3.2%) surgery was more effective (95-100%) than treatment with 131 I (60-70%) but at a higher risk of hypothyroidism (24 vs 0%). It is imperative to improve the methods of estimating the amount of 131 I to be administered in euthyroid goiter with autonomy. Selection of patients with autonomy in euthyroid goiter for definite treatment is difficult, since until now their risk to become hyperthyroid cannot be predicted properly. (orig.) [de

    Metastases to the thyroid gland are uncommon. Renal, lung, breast, and colon cancer and melanoma are the most common primary diseases implicated. Few retrospective series have been reported. Treatment decisions must be individualized, and will depend on the state of systemic disease. Selected patients could benefit from surgical treatment. Although most patients selected for surgery will not be cured, the aim of surgery is to avoid the complications of uncontrolled central neck disease. © 2013 Wiley Periodicals, Inc.

    The purpose of this study was to clarify the efficacy of radioiodine (RI) therapy in Japanese patients with autonomously functioning thyroid nodules (AFTNs). We performed a retrospective analysis to assess the management of AFTN patients. Thyroid lobectomy was performed to treat toxic adenoma (TA) patients, and total thyroidectomy to treat toxic multinodular goiter (TMNG) patients. RI therapy was administered in the form of a single dose (500 MBq) of isotope in the outpatient clinic. Percutaneous ethanol injection therapy (PEIT) was performed under ultrasound guidance. Of the total 205 patients, consisting of 159 TA and 46 TMNG patients, 99 underwent surgery, 50 received RI therapy, and 56 received PEIT. Remission of thyrotoxicosis was achieved in all of the patients who were treated surgically. Hypothyroidism was documented in six of the 72 patients who were treated surgically other than by total thyroidectomy. Remission of thyrotoxicosis was observed in 43 of the 50 patients who were treated by RI therapy. Nine TA patients developed hypothyroidism during the follow-up period after RI therapy. Several PEIT sessions were required to achieve a remission of thyrotoxicosis. Remission of thyrotoxicosis was achieved in 29 of the 56 patients treated by PEIT, and thyrotoxicosis recurred in 17 these 56 patients. Surgery is the treatment of choice for large nodules and nodules that are resistant to other treatments, because it allows prompt control of thyrotoxicosis. RI therapy is a safe and effective means of controlling thyrotoxicosis in AFTN patients. We conclude that RI therapy is the treatment of choice for definitive treatment of AFTN patients who do not have local compression symptoms. (author)

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

    Factors affecting the effect of {sup 131}I treatment and survival after pulmonary metastases in patients with differentiated thyroid cancer, were studied. Between 1984-1999, pulmonary metastases was observed in 51 out of 153 patients with differentiated thyroid cancer at our institution. Of these 41 patients had papillary and 10 follicular thyroid cancer. There were 37 females and 14 males with mean age ({+-}S.D.) of 50.5{+-}19.0 years. These 51 patients were subjected to {sup 131}I therapy. The effect of {sup 131}I treatment and the prognostic values of the following variables were examined: sex, age at the time of {sup 131}I treatment, histologic type of cancer, size of pulmonary metastases on CT, total-body scintigraphy with {sup 201}Tl and {sup 131}I, serum thyroglobulin levels and presence of metastases in distant sites other than lung. The effect of {sup 131}I treatment was evaluated by means of changes in the number and size of metastatic shadows on chest CT and by serum thyroglobulin levels. The minimum duration of follow-up was 12 months. Therapeutic {sup 131}I dose scans revealed detectable uptake in 25 of 51 patients. Therapeutic {sup 131}I dose uptake was achieved more frequently in patients under 40 years of age and in those with follicular cancers. Of the 51 patients, 13 were evaluated to be treated successfully. Those under 40 years of age, with {sup 131}I up-take in the lung and presence of other metastases showed a good response to treatment than others. Follicular cancer showed a more significant association with coarse type of lung metastases (>5 mm in diameter on chest CT) and good {sup 131}I uptake than papillary cancer. Of all the variables studied, the best prognosis for survival was demonstrated by increased {sup 131}I uptake in pulmonary metastases. These results indicate that age, {sup 131}I uptake and presence of other metastases are important factors in predicting the effect of {sup 131}I treatment for pulmonary metastases of

    The refractive surgery includes a lot of procedures for changing the refraction of the eye to obtain a better visual acuity with no glasses or contact lenses. LASIK is the most commonly performed laser refractive surgery today. The goal is to present the postoperative evolution of the refraction and visual acuity after LASIK for Mixed and Hyperopic Astigmatism. The results show that LASIK is safe and predictible if we have well performed interventions and well-selected patients.

    Health-related quality of life (HRQOL) in differentiated thyroid cancer (DTC) research has so far received little attention and available results are conflicting. We studied the HRQOL of radioiodine-naive DTC patients in comparison with the general population (GP), investigated the course of HRQOL up to 30 months after radioiodine remnant ablation (RAA) and sought to identify patient characteristics associated with HRQOL. We analysed data from routine HRQOL monitoring at a nuclear medicine department. Between 2005 and 2013, a total of 439 thyroid cancer patients (all histologies) completed the EORTC Quality of Life Questionnaire Core-30 (QLQ-C30) at least once during their treatment at the department. We compared patients' baseline HRQOL scores before RAA with scores from age-matched and sex-matched controls from the Austrian GP. We then determined the course of HRQOL over the 30 months after RAA and assessed the impact of the following clinical variables on HRQOL: method of thyroid-stimulating hormone (TSH) stimulation, histology (papillary vs. follicular) and disease stage. A total of 284 patients (mean age 48.3 years, SD 15.0 years; 71.6 % women; 80.7 % papillary type) with a baseline HRQOL assessment before RAA were available. We found clinically meaningful differences in the detriment in patients on almost all domains. These were largest for fatigue (23 points) and role functioning (25 points). Data from 241 patients (mean age 48.6 years, SD 15.9 years; 68.9 % women; 76.3 % papillary type) were included in the longitudinal analysis. Investigating the course of HRQOL, a significant improvement over time was found for role and emotional functioning, fatigue, pain, and dyspnoea. A range of HRQOL scores were improved in patients with exogenous TSH stimulation, but some scores both in patients with exogenous TSH stimulation and in those followed for 30 months, especially fatigue and role functioning, did not reach levels in the GP sample. Our results show that

    Bariatric surgery is performed mostly on obese women of reproductive age. Many authors have studied pregnancy outcomes after bariatric surgery. Only a small number of studies have analyzed the impact of maternity on the results of bariatric surgery. To study the effect of pregnancy on long-term outcomes of bariatric surgery. Lille University Hospital. A retrospective study was conducted on 591 women aged 18 to 42 years who had undergone laparoscopic adjustable gastric band (LAGB) surgery or laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery between 1996 and 2012. A comparison of the results after a 5-year follow-up was performed between patients who became pregnant after their bariatric surgery (pregnant group, n = 84) and postoperative nonpregnant women (nonpregnant group, n = 507). At the 5-year visit, 84.8% patients were seen. The preoperative body mass index (BMI) was the same in the 2 groups (pregnant group: 47.8±6.9 kg/m(2); nonpregnant group: 47.5±7.2 kg/m(2); P = .755). The percentage of excess weight loss (%EWL) was lower in the pregnant group at 2 years (pregnant group = 45.9±24.6%; nonpregnant group = 56.9±28.6%, P = .002) but was similar at 5 years (47.7±27.7% versus 49.9±28.9%, P = .644). The decrease in co-morbidities was similar after 5 years. The gestational weight gain (GWG) was higher when the band was deflated during pregnancy (GWG =+12.7±10.5 kg) compared to the band without fluid removal (GWG =+4.9±7 kg) or laparoscopic Roux-en-Y gastric bypass (GWG =+4.4±1.1 kg) (Pbariatric surgery slows down postoperative weight loss but does not affect weight results at 5-year follow-up.

    Full Text Available Background Ocular manifestations of thyroid dysfunction constitute a wide clinical spectrum ranging from minor ocular discomfort, lid retraction, lid lag and ocular injection, to sight threatening eyeball protusion and optic nerve compression. Thyroid-related eye disorders are most commonly associated with Graves' disease, and this most frequently occurs in the setting of hyperthyroidism. However, in 10% of cases, typical eye signs have also been reported in euthyroid and hypothyroid states. The severity of thyroid eye disease has been linked to cigarette smoking. There is very little data specifically reporting the ocular manifestations of thyroid disease among black African patients and there is no known report from Nigeria. This pilot study therefore focused on documenting the ocular signs accompanying thyroid dysfunction in a black African population. Aim To evaluate the pattern of ocular complications, among patients treated for thyroid disorders, in a major Nigerian teaching hospital. Results A total of 75 patients with thyroid dysfunction, were evaluated, comprising 63 females and 12 males. There was a very low prevalence of smoking among patients (<5%. Graves' disease was the commonest thyroid disorder, representing 70% of cases. Seventy-eight percent of patients were hyperthyroid, 11.8% were euthyroid and only 9.8% of patients were hypothyroid. Commonest systemic symptoms were neck swelling (68.6%, weight loss (63.8%, tremors (60.9% and palpitations (59.4%. Two-thirds of patients reported ocular symptoms consisting mainly of painless eye swelling (66.7% and ocular irritation (58%. Conjunctival injection, lid lag and lid retraction were the commonest ocular signs. Chemosis, severe proptosis and ocular motility disorder were very rare. Optic neuropathy was found in 4 patients but was related to pre-existing glaucoma. Majority of patients required only ocular emollients and tear supplements.

    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.

    This prospective, observational study of a cohort of thyroid cancer patients in Germany focusses on the ''real-world'' practice in the management of thyroid cancer patients. This report includes data from 2376 patients with primary differentiated thyroid carcinoma first diagnosed in the year 1996. The study reveals considerable differences in actual practice concerning surgery and radioiodine treatment. The results indicate that consensus is lacking with respect to the multimodality treatment approach for differentiated thyroid carcinoma. Our analysis represents the most current and comprehensive national assessment of presenting patient characteristics, diagnostic tests, treatment and complications for thyroid cancer. (orig.)

    Aim: The presented study prospectively evaluates the efficacy of optimized radioiodine therapy in patients (pts) with multifocal (MFA) and disseminated (DISA) autonomy. The target dose was related to the total thyroid volume and was increased in moderate and nonlinear increments for 150 to 300 Gy dependent on the pretherapeutic Tc-99m pertechnetate thyroid uptake under suppression (TcTUs). Patients with focal autonomy were treated with a target dose independent of TcTUs and were used as control group. Methods: The data of 641 pts (518 women, 123 men) were evaluated, 466 pts with MFA or DISA and 175 pts with focal autonomy. In pts with MFA and DISA the target dose was increased in four steps: TcTUs 3-6%: 200 Gy, >6-12%: 250 Gy and >12%: 300 Gy. In pts with focal autonomy a fixed target dose of 300 or 400 Gy was applied. The radioactivity to be administered was calculated using a modified Marinelli formula. The follow-up examination was performed at the earliest after four, on average after eight months. Normalization of TSH was the only criterion for successful therapy. Results: The success rate in pts with latent or manifest hyperthyroidism in focal autonomy was 91.5%, thereby was not successful in 5.1% and hypothyroidism occurred in 3.4%. The average success rate in pts with MFA and DISA was 91.5%, therapy failed in 7.5% and a very low rate of 1% with hypothyroidism was seen. Conclusion: The presented optimized therapy concept with calculated, nonlinear increase of the target dose according to the TcTUs-level guaranteed even in MFA and DISA a high success rate comparable to that in focal autonomy along with a very low rate of hypothyroidism.

    Background: Thyroid enlargement is one of the common problems in patients presenting at outpatients department of ENT particularly in females. Thyroid nodules are common, thyroid cancer is uncommon and the most common way for it to present is as a solitary thyroid nodule. This study was conducted to evaluate the sensitivity and specificity of Fine Needle Aspiration Cytology (FNAC) in thyroid diseases. Method: This prospective analytic study was conducted at ENT Department of Karachi Medical and Dental College/Abbasi Shaheed Hospital during year 2004-8. One hundred and five cases were enrolled who underwent thyroid surgery after complete evaluation by history, clinical examination, Thyroid profile, Thyroid Scintigraphy, Ultrasound neck and FNAC. In cases which were revealed malignant by FNAC, CT scan were done to see the extent of disease and neck node status. Surgery was done in all cases and specimens sent for histopathology. Results: Male to female ratio of the patients was 1:8.5. Most common lesion was benign nodule (96). Malignant lesions were 9 in FNAC. In histopathology, the benign nodules were 92, and malignant cases were 13. Sensitivity of FNAC was 61.53% and specificity was 98.9%. Conclusion: FNAC in Thyroid has high sensitivity and specificity.

    Background Thyroid-stimulating hormone (TSH) is used as the first-line test of thyroid function. Siemens Healthcare Diagnostics recommend that Siemens Centaur reagents must be protected from light in the assay information and on reagent packaging. We have compared the effect of light exposure on results using Siemens TSH-3Ultra and follicle-stimulating hormone reagents. The thyroid-stimulating hormone reagent includes fluoroscein thiocyanate whereas the follicle-stimulating hormone reagent does not. Methods Three levels of quality controls were analysed using SiemensTSH-3Ultra and follicle-stimulating hormone reagent packs that had been kept protected from light or exposed to light at 6-h intervals for 48 h and then at 96 h. Results Thyroid-stimulating hormone results were significantly lower after exposure of TSH-3Ultra reagent packs to light. Results were >15% lower at all three levels of quality control following 18 h of light exposure and continued to decrease until 96 h. There was no significant difference in follicle-stimulating hormone results whether reagents had been exposed to or protected from light. Conclusions Thyroid-stimulating hormone results but not follicle-stimulating hormone results are lowered after exposure of reagent packs to light. Laboratories must ensure that TSH-3Ultra reagents are not exposed to light and analyse quality control samples on every reagent pack to check that there has not been light exposure prior to delivery. The labelling on TSH-3Ultra reagent packs should reflect the significant effect of light exposure compared with the follicle-stimulating hormone reagent. We propose that the effect of light exposure on binding of fluoroscein thiocyanate to the solid phase antibody causes the falsely low results.

    Parathyroid autotransplantation is an easy procedure with a low complication rate. We adopted the transplantation into the sternocleidomastoid muscle, which allows an easier and time-saving surgical procedure using the same surgical incision. In this study, we retrospectively reviewed the records of 396 consecutive patients, who underwent total thyroidectomy for benign thyroid disease. In all cases in which a parathyroid was damaged or inadvertently removed, the gland was transplanted; before the autotransplantation, the parathyroid tissue was put in a cell culture nutrient solution for 5 min, afterward fragmented, and then was transplanted in the sternocleidomastoid muscle. To demonstrate a beneficial effect of the cell nutrient solution step, we compared data of transplanted patients with a control group of cases (n = 190) undergoing a standard immediate autotransplantation. We divided patients in two main groups: group A (n = 160) including subjects that underwent one or more parathyroid gland autotransplantation using the cell nutrient solution, and group B (n = 236) concerning those who were not transplanted. Among patients, 62 hypocalcemias occurred, 40 in the group A and 22 in the group B (P culture nutrient solution before gland transplantation.

    Full Text Available Objective The incidental thyroid lesion is a common finding during general imaging studies. Their management has been the subject of numerous studies and recommendations. Parathyroid disease workup necessitates imaging investigation of the adjacent thyroid gland and therefore provides a unique window to the perioperative management of thyroid incidentaloma. The specific prevalence of incidental thyroid lesions in the context of parathyroid disease is unknown. We seek to investigate its prevalence during parathyroid workup and surgery and to ascertain if there was a change in management of these patients. Study Design Five-year retrospective database review. Setting Tertiary care medical center. Subjects and Methods The source and indication for referral, preoperative investigation findings, and management of the incidental thyroid lesions were examined. The actual procedure performed and final pathology results were assessed. Results A total of 98 patients and 106 operations, including revision surgeries, were identified. There were 21 incidental thyroid lesions (21.4% detected, whereby 15 patients underwent fine-needle aspirations and 12 subsequently had diagnostic hemithyroidectomies. This decision was made preoperatively in 5 patients and intraoperatively in 7 patients at the time of parathyroid surgery. Along with other pathologies, there were 7 patients with micropapillary thyroid carcinoma identified. Conclusions In our series, the prevalence of incidental thyroid lesion and thyroid malignancy is comparable to the general population. The management of the initial parathyroid disease in our patients was altered by the imaging and cytological findings of these thyroid lesions. This has implications on perioperative counseling of the thyroid and parathyroid disease.

    Thyroid nodules diagnosed as Bethesda category IV [follicular neoplasm/suspicious for follicular neoplasm (FN/SFN)] are recommended for surgery. However, only 10%-40% of these nodules turn out to be malignant on histopathological examination. Therefore, selection for surgery of nodules diagnosed as Bethesda category IV is important. We aimed to define predictive factors for malignancy and factors associated with triage to surgery. The records of all patients with nodules who underwent fine needle aspiration biopsy (FNAB) and classified by Bethesda reporting system as FN/SFN between January 2011 and July 2017 at our institution were reviewed. Univariate and multivariate analysis were performed to select independent factors associated with thyroid cancer, and with triage to surgery. Using independent risk factors for malignancy predictive index categories were created. Among 6910 nodules that underwent FNAB, 180 (2.6%) were diagnosed as FN/SFN. Of the 180 patients, 139 (77%) underwent surgery with the associated malignancy rate of 37% (51/139) (upper boundary). Risk of malignancy among all FN/SFN nodules was 28% (lower boundary). Solid structure, size ≥ 4 cm, microcalcification, hypoechogenicity, and increased vascularization were found to be significant and independent risk factors associated for malignancy. None of the clinical and ultrasound factors were associated with triage to surgery. Our findings showed that using predictive factors for malignancy in the Bethesda IV category as risk indices, 17% of patients who had nodules without any risk factors could be spared surgery. Predictive indices could be considered for the malignancy risk and for selection of patients for surgery. © 2018 Wiley Periodicals, Inc.

    As surgical robots have become increasingly used, verification of their usefulness in the general thoracic surgery field is required. Initial results of robot-assisted thoracoscopic surgery in Japan were investigated. A questionnaire survey was performed to retrospectively examine the current status of robotic surgery for general thoracic disease in Japan. The subjects were 112 cases performed by the end of September 2012 at 9 institutions. There were 60 cases of primary lung cancer, 38 cases of anterior-middle mediastinal disease, and 14 cases of posterior mediastinal disease. In lung cancer cases, the operative time was 284.7 min, the blood loss was 129 mL, the drainage period was 3.3 days, and the conversion rate was 3.3 %. The incidence of postoperative complications was 6.7 %. The postoperative hospital stay was 8.2 days. In cases of anterior-middle mediastinal disease, the operative time was 184.3 min, the blood loss was 43.8 mL, the drainage period was 2.3 days, and there was no conversion. The incidence of postoperative complications was 7.9 %. The postoperative hospital stay was 7.1 days.

    2013-01-01

    Objective: We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features of thyroid nodules that had inconclusive ultrasonography-guided fine-needle aspiration (FNA) results. Methods: A total of 88 thyroid nodules in 88 patients who underwent ultrasonography-guided CNB because of previous inconclusive FNA results were evaluated. The patients were classified into three groups based on ultrasonography findings: Group A, which was suspicious for papillary thyroid carcinoma (PTC); Group B, which was suspicious for follicular (Hurthle cell) neoplasm; and Group C, which was suspicious for lymphoma. The final diagnoses of the thyroid nodules were determined by surgical confirmation or follow-up after ultrasonography-guided CNB. Results: Of the 88 nodules, the malignant rate was 49.1% in Group A, 12.0% in Group B and 90.0% in Group C. The rates of conclusive ultrasonography-guided CNB results after previous incomplete ultrasonography-guided FNA results were 96.2% in Group A, 64.0% in Group B and 90.0% in Group C (p=0.001). 12 cases with inconclusive ultrasonography-guided CNB results were finally diagnosed as 8 benign lesions, 3 PTCs and 1 lymphoma. The number of previous ultrasonography-guided FNA biopsies was not significantly different between the conclusive and the inconclusive result groups of ultrasonography-guided CNB (p=0.205). Conclusion: Ultrasonography-guided CNB has benefit for the diagnosis of thyroid nodules with inconclusive ultrasonography-guided FNA results. However, it is still not helpful for the differential diagnosis in 36% of nodules that are suspicious for follicular neoplasm seen on ultrasonography. Advances in knowledge: This study shows the diagnostic contribution of ultrasonography-guided CNB as an alternative to repeat ultrasonography-guided FNA or surgery. PMID:23564885

    Process, subjects, methods, results and tasks of the title surveys are described, where the others involve the survey of internal and external exposures in Fukushima residents. The simplified survey for thyroid internal exposure of children was based on the request (Mar. 23-25, 2011) of the Nuclear Safety Committee with data of System for Prediction of Environmental Emergency Dose Information (SPEEDI) and was conducted on Mar 24-30 in 1,080 infants/children of age range 0-15 y. Aloka NaI scintillation survey meter was used for measurement of thyroid radioactivity by contacting the detector with the organ portion. The standard limit was 0.2 micro-Sv/h (100 mSv eq./y for 1 year old child). Net dose rates were found to be 0 and <0.04 micro-Sv/h in 55.4% and 99.0% of children, respectively, and were thus lower than the standard in all children. Reliability and error in the measurement should be validated for explanation of the results. The investigations of internal exposures in Fukushima 174 residents were firstly performed on Japanese authority's request by the whole body counting in National Institute of Radiological Sciences (NIRS), and then those in 6,434 residents, from Aug. to Oct. (6,608 in total). Exposure at <1 mSv of the committed effective dose equivalent was found in 99.7% of residents and the maximum, 3 mSv, in 2 residents. The dose estimated by various institutions hereafter should be assessed along with the standardized scenario. The external exposure was investigated by inputting the data (1,727 residents, Mar. 11-July 11) of Fukushima Prefectural Health Management into the system to estimate the dose developed by NIRS. Subjects were 138 radiation workers and 1,589 people (F/M 675/914) of 3 regions near the Power Station: when excepting for the workers, 62.8% of subjects were exposed to <1 mSv, 97.4% to <5 mSv, and 99.7% to <10 mSv. Four people were exposed to 10 mSv or more, one of whom, to the maximum of 14.5 mSv. (T.T.)

    Full Text Available Abstract Introduction Papillary thyroid carcinoma and medullary thyroid carcinoma are two different thyroid neoplasia. The simultaneous occurrence of medullary thyroid carcinoma and papillary thyroid carcinoma as a collison tumor with metastases from both lesions in the regional lymph nodes is a rare phenomenon. Case presentation A 32-year-old Iranian man presented with a fixed anterior neck mass. Ultrasonography revealed two separate thyroid nodules as well as a suspicious neck mass that appeared to be a metastatic lesion. The results of thyroid function tests were normal, but the preoperative calcitonin serum value was elevated. Our patient underwent a total thyroidectomy with neck exploration. Two separate and ill-defined solid lesions grossly in the right lobe were noticed. Histological and immunohistochemical studies of these lesions suggested the presence of medullary thyroid carcinoma and papillary thyroid carcinoma. The lymph nodes isolated from a neck dissection specimen showed metastases from both lesions. Conclusions The concomitant occurrence of papillary thyroid carcinoma and medullary thyroid carcinoma and the exact diagnosis of this uncommon event are important. The treatment strategy should be reconsidered in such cases, and genetic screening to exclude multiple endocrine neoplasia 2 syndromes should be performed. For papillary thyroid carcinoma, radioiodine therapy and thyroid-stimulating hormone suppressive therapy are performed. However, the treatment of medullary thyroid carcinoma is mostly radical surgery with no effective adjuvant therapy.

    Full Text Available Spinal metastasis of differentiated thyroid cancer can have a favorable prognosis if radical surgery is performed. We encountered a case of spinal metastasis involving three anterior vertebral bodies at the posterior element fusion level and successfully achieved adequate stability by radical surgery involving only the anterior elements. A 67-year-old woman who had numbness and muscle weakness in the lower limbs caused by metastatic spinal tumor at the posterior element fusion level of L1–L3 vertebrae was treated with radical surgery of only the anterior element to gain stability. Similar situations may occur in cases involving other malignant tumor metastases or spinal primary tumors. If such a case occurs, this method could be useful in preventing metastasis to the posterior element.

    Full Text Available OBJECTIVE: To evaluate early and mid-term results in patients undergoing proximal thoracic aortic redo surgery. METHODS: We analyzed 60 patients (median age 60 years, median logistic EuroSCORE 40 who underwent proximal thoracic aortic redo surgery between January 2005 and April 2012. Outcome and risk factors were analyzed. RESULTS: In hospital mortality was 13%, perioperative neurologic injury was 7%. Fifty percent of patients underwent redo surgery in an urgent or emergency setting. In 65%, partial or total arch replacement with or without conventional or frozen elephant trunk extension was performed. The preoperative logistic EuroSCORE I confirmed to be a reliable predictor of adverse outcome- (ROC 0.786, 95%CI 0.64-0.93 as did the new EuroSCORE II model: ROC 0.882 95%CI 0.78-0.98. Extensive individual logistic EuroSCORE I levels more than 67 showed an OR of 7.01, 95%CI 1.43-34.27. A EuroSCORE II larger than 28 showed an OR of 4.44 (95%CI 1.4-14.06. Multivariate logistic regression analysis identified a critical preoperative state (OR 7.96, 95%CI 1.51-38.79 but not advanced age (OR 2.46, 95%CI 0.48-12.66 as the strongest independent predictor of in-hospital mortality. Median follow-up was 23 months (1-52 months. One year and five year actuarial survival rates were 83% and 69% respectively. Freedom from reoperation during follow-up was 100%. CONCLUSIONS: Despite a substantial early attrition rate in patients presenting with a critical preoperative state, proximal thoracic aortic redo surgery provides excellent early and mid-term results. Higher EuroSCORE I and II levels and a critical preoperative state but not advanced age are independent predictors of in-hospital mortality. As a consequence, age alone should no longer be regarded as a contraindication for surgical treatment in this particular group of patients.

    The incidence of papillary microcarcinoma (PMC) of the thyroid is rapidly increasing globally, making the management of PMC an important clinical issue. Excellent oncological outcomes of active surveillance for low-risk PMC have been reported previously. Here, unfavorable events following active surveillance and surgical treatment for PMC were studied. From February 2005 to August 2013, 2153 patients were diagnosed with low-risk PMC. Of these, 1179 patients chose active surveillance and 974 patients chose immediate surgery. The oncological outcomes and the incidences of unfavorable events of these groups were analyzed. In the active surveillance group, 94 patients underwent surgery for various reasons; tumor enlargement and the appearance of novel lymph node metastases were the reasons in 27 (2.3%) and six patients (0.5%), respectively. One of the patients with conversion to surgery had nodal recurrence, and five patients in the immediate surgery group had a recurrence in a cervical node or unresected thyroid lobe. All of these recurrences were successfully treated. None of the patients had distant metastases, and none died of the disease. The immediate surgery group had significantly higher incidences of transient vocal cord paralysis (VCP), transient hypoparathyroidism, and permanent hypoparathyroidism than the active-surveillance group did (4.1% vs. 0.6%, p < 0.0001; 16.7% vs. 2.8%, p < 0.0001; and 1.6% vs. 0.08%, p < 0.0001, respectively). Permanent VCP occurred only in two patients (0.2%) in the immediate surgery group. The proportion of patients on L-thyroxine for supplemental or thyrotropin (TSH)-suppressive purposes was significantly larger in the immediate surgery group than in the active surveillance group (66.1% vs. 20.7%, p < 0.0001). The immediate surgery group had significantly higher incidences of postsurgical hematoma and surgical scar in the neck compared with the active surveillance group (0.5% vs. 0%, p < 0.05; and 8.0% vs

    The purpose of this study was to validate whether ex vivo multispectral photoacoustic imaging can be used to differentiate malignant tissue, benign nodules, and normal human thyroid tissue. Fifty patients undergoing thyroidectomy because of thyroid lesions participated in this study. Multispectral photoacoustic imaging was performed on surgically excised thyroid tissue, and chromophore images that represented optical absorption of deoxyhemoglobin, oxyhemoglobin, lipid, and water were reconstructed. After the imaging procedure, the pathologist marked malignant tissue, benign nodules, and normal regions on histopathologic slides, and digital images of the marked histopathologic slides were obtained. The histopathologic images were coregistered with chromophore images. Areas corresponding to malignant tissue, benign nodules, and normal tissue were defined on the chromophore images. Pixel values within each area were averaged to determine the mean intensities of deoxyhemoglobin, oxyhemoglobin, lipid, and water. There was a statistically significant difference between malignant and benign nodules with respect to mean intensity of deoxyhemoglobin (p = 0.014). There was a difference between malignant and normal tissue in mean intensity of deoxyhemoglobin (p = 0.003), lipid (p = 0.001), and water (p multispectral photoacoustic imaging can be used to differentiate malignant and benign nodules and normal human thyroid tissue.

    Full Text Available To identify the determinants of operative time for thyroidectomy and quantify the relative influence of preoperative and intra-operative factors.Anticipation of operative time is key to avoid both waste of hospital resources and dissatisfaction of the surgical staff. Having an accurate and anticipated planning would allow a rationalized operating room use and may improve patient flow and staffing level.We conducted a prospective, cross-sectional study between April 2008 and December 2009. The operative time of 3454 patients who underwent thyroidectomy performed by 28 surgeons in five academic hospitals was monitored. We used multilevel linear regression to model determinants of operative time while accounting for the interplay of characteristics specific to surgeons, patients, and surgical procedures. The relative impact of each variable on operative time was estimated.Overall, 86% (99% CI 83 to 89 of operative time variation was related to preoperative variables. Surgeon characteristics accounted for 32% (99% CI 29 to 35 of variation, center location for 29% (99% CI 25 to 33, and surgical procedure or patient variables for 24% (99% CI 20 to 27. Operative time was significantly lower among experienced surgeons having practiced from 5-19 years (-21.8 min, P<0.05, performing at least 300 thyroidectomies per year (-28.8 min, P<0.05, and with increasing number of thyroidectomies performed the same day (-11.7min, P<0.001. Conversely, operative time increased in cases of procedure supervision by a more experienced surgeon (+20.0 min, P<0.001. The remaining 13.0% of variability was attributable to unanticipated technical difficulties at the time of surgery.Variation in thyroidectomy duration is largely explained by preoperative factors, suggesting that it can be accurately anticipated. Prediction tools allowing better regulation of patient flow in operating rooms appears feasible for both working conditions and cost management.

    Full Text Available We sought to elucidate the correlation between shear wave velocity (SWV and fibrosis in thyroid by precisely assessing pathological structures inside 5 × 5 mm2 regions of interest (ROIs of resected specimens, under conditions that excluded physical artifacts. The materials were unselected thyroid and lymph node specimens resected during thyroid surgery. Immediately after surgery, fresh unfixed thyroid and metastatic lymph node specimens were suspended in gel phantoms, and SWV was measured. Upon pathological examination of each specimen, the extent of fibrosis was graded as none, moderate, or severe. A total of 109 specimens were evaluated: 15 normal thyroid, 16 autoimmune thyroiditis, 40 malignant nodules, 19 benign thyroid nodules, and 19 metastatic lymph nodes. When all specimens were classified according to the degree of fibrosis determined by pathological imaging, the mean SWV was 1.49±0.39 m/s for no fibrosis, 2.13±0.66 m/s for moderate fibrosis, and 2.68±0.82 m/s for severe fibrosis. The SWVs of samples with moderate and severe fibrosis were significantly higher than those of samples without fibrosis. The results of this study demonstrate that fibrosis plays an important role in determining stiffness, as measured by SWV in thyroid.

  12. Body contouring following massive weight loss resulting from bariatric surgery.

    Chandawarkar, Rajiv Y

    2006-01-01

    A sharp increase in bariatric surgery has resulted in spike in the population of patients seeking body-contouring procedures. Skin and soft tissue redundancy of the trunk, buttocks, breasts, upper arms, and thighs following massive weight loss is unsightly and results in medical problems such as musculoskeletal strain from increased tissue weight, intertrigo or functional limitation with walking, maintaining adequate hygiene, bowel and bladder habits and sexual activity. These elements compound the inherent psychosocial issues related to massive weight loss. Using time-tested plastic surgical techniques, several operations have been designed and perfected to address the needs of these patients. These include breast, thigh and lower body lift, abdominoplasty, face and neck lifts as well as brachioplasty or arm lift. Recognizing that there is a qualitative as well as a quantitative difference in the type and amount of tissues in postbariatric patients these techniques have been suitably refined to optimize outcomes and provide safe and durable re-contouring. Consequently, bariatric surgery and the subsequent weight loss require an additional 2-3 years commitment towards body contouring procedures. Restoring their body image through reshaping procedures is an integral part of completing the treatment of post-weight-loss patients. Strategic skills in terms of assessment of each patient, careful planning, timing, especially for patient safety and technique are fundamental for the success of these often complex and extensive procedures.

  14. Technical tips to enhance micrografting results in burn surgery.

    Science.gov (United States)

    Chong, Si Jack; Choke, Abby; Tan, Bien-Keem

    2017-08-01

    The lack of autograft donor site is one of the greatest limiting factors for the treatment of extensive burn. Micrografting is an important revolution in burn surgery where autografts are cut into small pieces for wide and rapid coverage of burn wound. Our early experiences with the current standard micrografting technique were fraught with poor graft take as well being time and labor intensive. We have improvised our technique, where we combined the use of allograft to serve as a carrier for the micrograft. The objective of this paper is to share our experience in micrografting and several technical tips which had enhanced our micrografting results. The improvisation in our technique includes: (1) Single-stage 'micrograft-allograft sandwich method' where allograft served as a direct carrier for the micrografts. Micrografts were laid uniformly 1cm apart onto allograft sheets, creating a 1:9 expansion ratio. This technique replaced the original two stage method. (2) The use of the Meek device (Humeca, Netherlands) to prepare micrograft. The Meek device can rapidly produce 3mm micrografts for easy transfer with a fine forceps. (3) The use of slow-acting fibrin sealant to promote graft take and hemostasis. (4) A two-team approach for micrograft preparation where one team processes micrograft and another prepares the allograft sheets. This reduces the lag time between micrograft preparation and grafting, and reduces the overall surgery time. Micrografting remains an important treatment for major burn surgery. The aim of micro-allograft combination is to allow autografts re-epithelization under a reliable temporary skin coverage in a single stage procedure. A prospective study is warranted to measure the objective outcome of this renewed technique. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

  16. Amiodarone-induced thyroid disorders: a clinical review

    Science.gov (United States)

    Loh, K.

    2000-01-01

    Although amiodarone is regarded as a highly effective anti-arrhythmic agent, its use may lead to alterations in thyroid gland function and/or thyroid hormone metabolism, partly because of its rich iodine content. Patients treated with amiodarone may manifest altered thyroid hormone profile without thyroid dysfunction, or they may present with clinically significant amiodarone-induced hypothyroidism or amiodarone-induced thyrotoxicosis. The former results from the inability of the thyroid to escape from the Wolff-Chaikoff effect. It prevails in areas with high dietary iodine intake, and it is readily managed by discontinuation of amiodarone or thyroid hormone replacement. Amiodarone-induced thyrotoxicosis occurs more frequently in areas with low iodine intake; it may arise from iodine-induced excessive thyroid hormone synthesis (type I) or destructive thyroiditis with release of preformed hormones (type II). Type I should be treated with thionamides alone or in combination with potassium perchlorate, whereas type II benefits from treatment with glucocorticoids. Surgery may be a feasible option for patients who require long-term amiodarone treatment.

    Purpose: To evaluate color-Doppler features predictive of focal Hashimoto's thyroiditis. Materials and methods: A total of 521 patients with 561 thyroid nodules that underwent surgeries or gun biopsies were included in this study. These nodules were divided into three groups: focal Hashimoto's thyroiditis (104 nodules in 101 patients), benignity other than focal Hashimoto's thyroiditis (73 nodules in 70 patients), and malignancy (358 nodules in 350 patients). On color Doppler sonography, four vascularity types were determined as: hypovascularity, marked internal flow, marked peripheral flow and focal thyroid inferno. The {chi}{sup 2} test was performed to seek the potential vascularity type with the predictive ability of certain thyroid pathology. Furthermore, the gray-scale features of each nodule were also studied. Results: The vascularity type I (hypovascularity) was more often seen in focal Hashimoto's thyroiditis than other benignity and malignancy (46% vs. 20.5% and 19%). While the type II (marked internal flow) showed the opposite tendency (26.9% [focal Hashimoto's thyroiditis] vs. 45.2% [other benignity] and 52.8% [malignancy]). However, type III (marked peripheral flow) was unable to predict any thyroid pathology. Importantly, type IV (focal thyroid inferno) was exclusive to focal Hashimoto's thyroiditis. All 8 type IV nodules appeared to be solid, hypoechoic, and well-defined. Using 'focal thyroid inferno' as an indicator of FHT, the diagnostic sensitivity and specificity were 7.7% and 100% respectively. Conclusions: The vascularity type of 'focal thyroid inferno' is specific for focal Hashimoto thyroiditis. Recognition of this particular feature may avoid unnecessary interventional procedures for some solid hypoechoic thyroid nodules suspicious of malignancy.

    Full Text Available Petroclival meningiomas represent only 10% of all meningiomas located in the posterior fossa, but are some of the most formidable challenges in skull base surgery. We described our recent experience (2005-September2014 regarding the surgery of these tumors. We retrospectively analyzed surgical results and outcome in 11 cases of petroclival meningiomas. Most common symptoms in our series were headache and gait disturbance, while cranial nerves palsies represented the most common presenting signs. There were 8 females and 3 males, and the mean age was 52 years. Surgical approaches chosen for petroclival meningiomas in our series were retrosigmoid (9 patients and subtemporal transtentorial (2 patients. We achieved total tumor resection in 5 cases (45% and subtotal resection in 6 cases (55%. Overall outcome (total/subtotal resection was good in 6 cases, fair in 3 cases and poor in one case. One postoperative death occurred due to hemorrhagic midbrain infarction (9%. Complications were usually related to cranial nerve deficits: loss of hearing (2 patients, paresis of trochlear nerve (1 patient, trigeminal nerve (3 patients and facial nerve (1 patient. In 4 patients these cranial nerves deficits were transient. In one case, a patient developed postoperative hydrocephalus and needed shunt placement. Despite the fact that complications can be disastrous, we considered that an appropriate approach, combined with microsurgical techniques and a better understanding of the anatomy, greatly decrease the incidence and severity of complications and make feasible a total tumor resection.

    1998-01-01

    Aim: The presented study examines prospectively the efficiency of a dose concept for radioiodine therapy (RIT) adapted to the pretherapeutic 99m Tc-pertechnetate thyroid uptake under suppression (TcTU s ) in patients with multifocal (MFA) and disseminated (DISA) autonomy. This concept considers the total thyroid as target volume and uses target doses from 150 Gy to 300 Gy according to the TcTU s , which is as a measure for the 'autonomous volume' of the thyroid. Methods: The data of 75 patients (54 female, 21 male; age 71±9 years) with MFA or DISA were evaluated. RIT was performed on patients presenting with normal values for free triiodothyronine and thyroxine and endogenous suppression of the basal thyrotropin (TSH). The following target doses were used: For a TcTU s of 1,5-2,5% 150 Gy, for 2,51-3,5% 200 Gy, for 3,51-4,5% 250 Gy, and for >4,5% 300 Gy. The radiation dose to be administered was calculated using a modified Marinelli formula. The therapy was considered as successful when the basal TSH was above 0,5 mU/l and autonomous areas had disapeared in thyroid scintigraphy or the TcTU was below 1,5%, respectively. The average follow-up period was 8±4 months. Results: The success rates average to 92%. Only in one case a subsequent subclinical hypothyroidism and in a further case an immunogenic hyperthyroidism occured. Conclusion: The presented data indicate, that even patients with a marked autonomy (TcTU s >3,5%) can thus expected to be cured by of a onetime therapy with success rate of over 90% using the presented dose concept. The rate of early hypothyroidism can alltogether be estimated as very low. (orig.) [de

    Full Text Available Objective. To evaluate the efficacy and safety of percutaneous polidocanol injection (PPI in treating cystic thyroid nodules. Materials and Methods. A total of 158 cystic or predominantly cystic thyroid nodules (>80% cystic component in 143 patients were evaluated. 114 patients with compressive symptoms or aesthetic complaints were offered PPI. 44 individuals without compressive symptoms and aesthetic complaints who were only followed up clinically were used as the control group. The efficacy and safety of PPI were evaluated for 1 month, 3 months, 6 months, 9 months, and 12 months of follow-up. Results. In the PPI group, the mean baseline volume of 15.6±18.9 cm3 reduced at the 1-month follow-up to 5.1±5.6 cm3 (p<0.001 and 0.6±0.9 (p<0.001, and nodules shrunk according to the time after PPI (p<0.001. A complete response (if ≥70% decrease to PPI at the 12-month follow-up occurred in 100% of the cystic or predominant cystic nodules. None of the nodules recurred at the 12-month follow-up after PPI. The side effects were mild. Twenty patients (17.5% developed mild localized pain, and fourteen cases (12.3% experienced mild or moderate fever after PPI. Conclusions. PPI is a safe and effective alternative to treat benign cystic or predominant cystic thyroid nodules.

    2006-01-01

    Aim: in combined focal and disseminated thyroid autonomy a variety of concepts in the treatment with radioiodine are used. The difference lies mainly in the calculation of the autonomous volume. This retrospective study shows a new method of calculating the autonomous volume. Patients and methods: in 398 patients with combined thyroid autonomy and good correlation of scintigraphically hot nodules and lesions defined by ultrasound the volume of the nodules is ascertained from scintigraphic and ultrasound parameters and the volume of the disseminated autonomous tissue is assessed with a weighting factor (VF). This factor is the ratio of impulse density in a ROI over the disseminated volume divided by the corresponding impulse density over the nodular volume of the thyroid scintigraphy. The sum of nodular volume and weighted perinodular volume gives the total autonomous volume. A standard radioiodine test gives the maximum iodine-131-uptake and effective half-life to calculate the activity to obtain a treatment dose of 400 Gy. Results: the rate of success with and without thyrostatic medication was 97% with an 18.6% rate of hypothyroidism observed from 4 months post therapy onwards. Conclusion: the use of the weighting factor VF in the treatment of combined autonomy leads to an excellent rate of success in patients with good correlation of functional imaging and ultrasound findings.

    INTRODUCTION: Basal cell carcinoma (BCC) is the most common malignant neoplasm with an annual incidence approaching 200/100,000 person-years. Mohs micrographic surgery (MMS) is widely used in North America and in Europe for treatment of BCC. This technique ensures radical tumour removal, sparing...... histopathological examination, in which 2% of the margin is examined. METHODS: In Denmark, MMS was first introduced by us in 2012. In the present study, we retrospectively included all patients who underwent MMS from May 2012 to June 2015. RESULTS: A total of 231 patients with 263 BCC were included. The mean age...... defects than standard excisions with 4 or 6 mm margins. Closure of skin defects was achieved by side-to-side closure in 49% and by local flaps in 40%. There were no relapses during the observation time. The safety, cosmetic and functional outcome were excellent. CONCLUSIONS: We recommend that MMS...

    Some antiemetics are effective in the treatment of postoperative pain and shivering, as well as for postoperative nausea and vomiting (PONV). The aim of this study was to investigate the effects of ramosetron and dexamethasone on PONV, pain, and shivering and to determine the correlations between nausea, pain, and shivering. For this study, 123 patients scheduled for thyroid surgery were randomly allocated to one of three groups: the control group (group C, n = 41), dexamethasone group (group D, n = 41), or the ramosetron group (group R, n = 41). The patients were treated intravenously with 2 mL of 0.9 % NaCl, 2 mL of 5 mg/mL dexamethasone, or 2 mL of 0.15 mg/mL ramosetron immediately after anesthesia. The overall incidence and severity of postoperative nausea and the level of antiemetic consumption were significantly lower in group R compared with group D, and these parameters were significantly lower in groups R and D than in group C. There were significant differences in the incidence and severity of shivering, severity of pain, and analgesic consumption between group C and group R or D, but the incidence of shivering, pain severity, and analgesic consumption did not differ between groups R and D. The severity of shivering was significantly lower in group R than in group D. The correlation coefficients for shivering and pain, shivering and nausea, and pain and nausea were 0.210 (P = 0.010), 0.106 (P = 0.198), and 0.190 (P = 0.035), respectively, in group C. Two antiemetic drugs, ramosetron and dexamethasone, significantly reduced the incidence and severity of postoperative nausea and the need for administration of rescue antiemetic drugs. Furthermore, both drugs effectively decreased the severity of pain and shivering. Ramosetron was superior to dexamethasone for reducing nausea, antiemetic consumption, and the severity of nausea, but not for reducing the incidence of shivering. Further studies are required to elucidate the correlations between postoperative

    Thyroid screening measurements for 131 I were performed on 58 travelers returning from Eastern and Western Europe to Boston after the Chernobyl reactor accident on April 26, 1986. The travelers consisted of both Americans arriving home after business or vacation and European nationals visiting relatives in the Boston area. For purposes of dosimetry the population was divided into three subpopulations--adult (greater than 18 yr old), children (less than or equal to 18 yr old), and two individuals, 17 and 26 wk pregnant. Seventy-four percent of the population had detectable quantities of 131 I thyroid burdens, ranging from 1 nCi (37 Bq) to 900 nCi (33,300 Bq). The highest adult radiation dose equivalent was 5.18 mrem (51.8 mSv). The children, however, had considerably higher dose equivalents with one infant receiving 37 rem (370 mSv). Several other children were above 1 rem (10 mSv). The fetal dose equivalents were less than 14 mrem (140 mu Sv). The presence of rain dominated those testing positive for 131 I. Radioactive fallout from the Chernobyl accident contaminated a wide range of Europe and a large population subsequently ingested radioactivity. The children exhibited the highest thyroid radiation dose equivalents of the individuals monitored in the present study. The significance of this is presently unknown

    In this paper we report on a successful management of multiple bone metastases from differentiated thyroid cancer. In 2007, a 75-year-old female patient, previously referred for thyroidectomy for multinodular goiter, underwent surgical removal of a lumbar mass with histological findings of metastasis from well differentiated thyroid cancer. After surgery, serum thyroglobulin (sTg) was 204.4 ng/mL. A diagnostic/dosimetric (123)I WBS was performed, following stimulation by rTSH. Serial WBSs were acquired, along with SPECT/CT and bone scan for localization of lesions. sTg raised to 3.810 ng/mL, and (123)I WBS showed thyroid remnants and numerous areas with high iodine-uptake corresponding to skeletal sites, the two largest loading on the skull, with osteolytic pattern. Calculated radiation absorbed dose for skull lesions, determined by mean of MIRD methodology, was 63.5 mGy/MBq. The patient underwent surgical removal of the two major skull lesions. Successively, 100 mCi (131)I was administered after stimulation by rTSH, with stimulated sTg 297 ng/mL. After 8 months, diagnostic WBS was negative both for remnants and metastases and rTSH-stimulated Tg was 0.6 ng/mL. To date, the patient has maintained sTg values <1 ng/mL during L-T4 suppressive therapy and after rTSH stimulations. In this unusual case of extensive bone cancerous involvement with high iodine avidity, a multidisciplinary approach based on surgery and dosimetry-guided radiometabolic therapy allowed to accurately assess the patient, execute a small number of treatments and achieve a complete remission of the disease in a very short time, with no additive morbidity.

    Purpose: To determine the outcome and prognostic factors for patients with localized epithelioid sarcoma treated with conservative surgery and radiotherapy (RT). Methods and Materials: The medical records of 24 patients with nonmetastatic epithelioid sarcoma treated with conservative surgery and RT were reviewed. Preoperative RT was given to 3 patients (median 46.4 Gy) and postoperative RT to 21 patients (median 64.5 Gy). A local (limb-sparing) surgical procedure was performed in all patients. Results: At a median follow-up of 131 months, 14 patients had relapsed and 13 patients had died. The actuarial overall and disease-free survival rate at 10 years was 50% and 37%, respectively. Local, nodal, and metastatic failure occurred in 7, 4, and 10 patients, respectively, yielding a 10-year actuarial local, nodal, and metastatic control rate of 63%, 81%, and 56%, respectively. Univariate analysis revealed that size ≤5 cm and extremity location were favorable prognostic factors for overall, disease-free, and metastasis-free survival. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 79% vs. 25% (p=0.002), 51% vs. 13% (p=0.03), and 79% vs. 13% (p 5 cm. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 77% vs. 39% (p 0.002), 56% vs. 0% (p=0.01), and 78% vs. 17% (p=0.01), respectively, for extremity vs. nonextremity location. Multivariate analysis of the factors correlating with the overall, disease-free, and metastasis-free survival confirmed the favorable prognostic significance of small lesion size. The prognostic significance of extremity location on univariate analysis was explained by an imbalance in the mean tumor sizes. Conclusions: Epithelioid sarcoma is an aggressive soft-tissue sarcoma, with high rates of local and distant relapse. Local control with conservative surgery and RT compares favorably to published surgical series. The poor outcome for tumors ≥5 cm in size emphasizes the need for

Demographics, intraoperative, and pathological aspects were correlated to our hypocalcemia findings. RESULTS: Age higher than 50 (p = 0.022 and complete thyroidectomy (p < 0.001 were considered risk factors for hypoparathyroidism. Complete thyroidectomy was considered a risk factor for the 48-hour laboratorial hypoparathyroidism (p = 0.004. There was no risk factor associated with the one-month laboratorial hypoparathyroidism. There was significance between the 48-hour and the one-month laboratorial hypoparathyroidism. CONCLUSIONS: Thyroidectomy extension is a risk factor for both the clinical and laboratorial hypoparathyroidism, whereas age is a risk factor for clinical hypoparathyroidism. The detection of 48-hour laboratorial hypoparathyroidism is a predisposing factor for the one-month laboratorial hypoparathyroidism. However, most of the cases were temporary.

    The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

    Purpose: Postoperative irradiation of endometrial cancer patients decreases the risk of local recurrence but is associated with a number of long-term sequelae. In a proportion of patients, no immediate postoperative radiotherapy is applied and this treatment is introduced only at relapse. The aim of our study was to assess the long-term results of salvage radiotherapy in previously nonirradiated endometrial cancer patients who developed local recurrence, and to evaluate the impact of patient- and treatment-related factors on treatment efficacy. Methods and Materials: We performed a detailed retrospective analysis of 73 endometrial cancer patients given radiotherapy for local recurrence after the initial surgery only. The mean age at diagnosis of the recurrence was 63 years (range, 39-78 years). Median time to recurrence was 11 months (range, 1-19 months). All recurrences were staged with the use of Perez modification of the International Federation of Gynecology and Obstetrics (FIGO) staging system for primary vaginal carcinoma. There were five (7%) Stage I patients, 43 (59%) Stage II patients, and 25 (34%) Stage III patients. Forty-four patients (60%) received both external beam irradiation (EBRT) and endovaginal brachytherapy (BRT), 17 (23%) received only BRT, and 12 (17%) received only EBRT. The mean total physical radiation dose was 75.9 Gy (range, 8-130 Gy), and the mean normalized total dose (NTD) calculated on the base of the linear-quadratic model was 86.6 Gy (range, 8.5-171.9 Gy). Median follow-up for alive patients was 8.8 years (range, 3-21 years). The impact of patient-, tumor-, and therapy-related factors on the treatment outcome was evaluated with the use of uni- and multivariate analyses. Results: Three- and 5-year overall survival rates were 33% and 25%, respectively. In the univariate analysis, lower stage of recurrent disease (p < 0.0005), combined EBRT and BRT (p 0.027), higher total radiation dose (p = 0.031), and higher NTD (p = 0.006) were

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

    Full Text Available 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.

    Full Text Available We here analyzed the prevalence of extra-thyroidal malignancies (EM in 6,386 female patients affected by different thyroid disease (TD. At first, an age-matched analysis of EM in all patients was performed. We then evaluated EM prevalence in four TD diagnostic categories: non-nodular TD (n = 2,159; solitary nodule (n = 905; multinodular TD (n = 2,871; differentiated thyroid cancers (n = 451. Finally, patients were grouped based on the absence (n = 3,820 or presence of anti-thyroglobulin (TgAb and/or anti-thyroperoxidase (TPOAb (n = 2,369, or anti-Thyroid Stmulating Hormone (TSH receptor autoantibodies (n = 197. A total of 673 EM were recorded. EM prevalence in TD patients was higher compared to the general population (Odds Ratio, OR 3.21 and the most frequent EM was breast cancer (OR 3.94, followed by colorectal (OR 2.18, melanoma (OR 6.71, hematological (OR 8.57, uterus (OR 2.52, kidney (OR 3.40 and ovary (OR 2.62 neoplasms. Age-matched analysis demonstrated that the risk of EM was maximal at age 0-44 yr (OR 11.28, remaining lower, but significantly higher that in the general population, in the 45-59 and 60-74 year age range. Breast and hematological malignancies showed an increased OR in all TD, while other cancers associated with specific TD. An increased OR for melanoma, breast and hematological malignancies was observed in both TPOAb and/or TgAb autoantibody negative and positive patients, while colorectal, uterus, kidney and ovary cancers showed an increased OR only in thyroid autoantibody negative patients. In conclusions, women affected by both benign and malignant TD, especially at a younger age and in absence of thyroid autoimmunity, have an increased risk of developing primary EM, thus requiring a careful follow-up and surveillance.

    To compare visual acuity outcomes, vision-related quality of life, and complications related to cataract surgery in eyes with and without glaucoma. Retrospective cohort study. Cataract surgery outcomes in cases with and without glaucoma from the Veterans Affairs Ophthalmic Surgical Outcomes Data Project were compared. We identified 608 glaucoma cases and 4306 controls undergoing planned cataract surgery alone. After adjusting for age, pseudoexfoliation, small pupil, prior ocular surgery, and anterior chamber depth, we found that glaucoma cases were more likely to have posterior capsular tear with vitrectomy (odds ratio [OR] 1.8, P = .03) and sulcus intraocular lens placement (OR 1.65, P = .03) during cataract surgery. Glaucoma cases were more likely to have postoperative inflammation (OR 1.73, P < .0001), prolonged elevated intraocular pressure (OR 2.96, P = .0003), and additional surgery within 30 days (OR 1.92, P = .03). Mean best-corrected visual acuity (BCVA) and Visual Function Questionnaire (VFQ) scores significantly improved after cataract surgery in both groups (P < .0001), but there were larger improvements in BCVA (P = .01) and VFQ composite scores (P < .0001) in the nonglaucoma vs the glaucoma group. A total of 3621 nonglaucoma cases (94.1%) had postoperative BCVA 20/40 or better, compared to 466 glaucoma cases (89.6%) (P = .0003). Eyes with glaucoma are at increased risk for complications and have more modest visual outcomes after cataract surgery compared to eyes without glaucoma. Despite this, glaucoma patients still experience significant improvement in vision-related outcomes after cataract extraction. Further study is needed to explore potential factors that influence cataract surgery outcomes in glaucomatous eyes. Published by Elsevier Inc.

Our teams at Kanazawa University and Tokyo Medical University groups began using the da Vinci Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA) in 2005. This series represents the first Japanese application of robotic technology for totally endoscopic open-heart surgery. : From January 2008 to February 2009, 10 patients (mean age: 46.8 ± 16.3 years, 70% women) underwent endoscopic atrial septal defect closure and resection of the left atrial myxoma using the da Vinci Surgical System and peripheral cardiopulmonary bypass technique. Of the 10 patients, nine were classified as New York Heart Association class II and 1 patient exhibited atrial arrhythmias. In addition, two patients required mitral valve plasty (n = 2) and tricuspid annuloplasty (n = 1). : Mean da Vinci Surgical System working time was 140.7 ± 57.4 minutes. Mean cardiopulmonary bypass and aortic cross clamp times were 103.1 ± 37.1 and 30.0 ± 16.9 minutes, respectively. There were no conversions to sternotomy or small thoracotomy. There were no hospital deaths. Mean intensive care unit and hospital stays were 1 day and 3.1 ± 0.3 days, respectively. All patients appreciated the cosmetic result and fast recovery. : Closed-chest atrial septal defect closure and myxoma resection performed using robotic techniques achieved excellent results and rapid postoperative recovery and provided an attractive cosmetic advantage over median sternotomy.

    The results of direct measurements of radioactive iodine content in the human thyroid gland (in Bryansk and Kaluga regions, Russia) and also available data on 131 I and 137 Cs contamination of the soil were used for investigation of correlations between the mean thyroid dose for adults in settlements and local levels of 137 Cs and/or 131 I soil contamination. On the basis of this analysis a model was developed showing how to evaluate retrospectively the thyroid absorbed doses. For individual dose reconstruction using an 'age/milk' scale, special questioning of inhabitants was carried out. Mean dose values in the exposed population of each contaminated Russian settlement were evaluated using the model. The total collective dose due to internal exposure of the thyroid gland by iodine radionuclides equates to 106,500 person.Gy in the population of the most contaminated territories of four Russian regions. The maximum value was found in the Bryansk region (73,000 person.Gy). New data concerning the delay in pasturing in different regions as well as time dependencies of the fallout were taken into account. As a result the dose estimations differ from previous published data. Comparisons between the developed method and the other independent approaches indicate a concordance within a factor 3. For application of the EPR tooth enamel dosimetry on a wide scale, estimation of accumulated external doses are demonstrated and analysed. There were about 2500 tooth samples measured from the contaminated region as well as from the non-contaminated territories of Russia.

    For stage I or II breast cancer, conservative surgery and radiation therapy are as effective as modified radical or radical mastectomy. In most cases, cosmetic considerations and the availability of therapy are the primary concerns. The extent of a surgical resection less than a mastectomy has not been a subject of a randomized trial and is controversial. It appears that removal of a quadrant of the breast for small lesions is safe but excessive. It may be possible to limit the breast resection to gross tumor removal for most patients while using wider resections for patients with an extensive intraductal component or for invasive lobular carcinoma. It also appears that excluding patients from breast conservation on the basis of positive margins on the first attempt at tumor excision may be unnecessarily restrictive. Although patients with an extensive intraductal component or invasive lobular carcinoma should have negative margins, it appears that a patient with predominantly invasive ductal carcinoma can be treated without re-excision if all gross tumor has been resected and there is no reason to suspect extensive microscopic disease. Patients with indeterminate margins should have a re-excision. Axillary dissection provides prognostic information and prevents progression of the disease within the axilla. Axillary dissections limited to level I will accurately identify a substantial number of patients who have pathologically positive but clinically negative nodes. When combined with radiation therapy to the axilla, a level I dissection results in a limited number of patients with progressive axillary disease. Patients with pathologically positive axillas and patients at particularly high risk for systemic disease because of the extent of axillary node involvement can be identified by dissections of levels I and II. 60 references.

    OBJECTIVE Adjacent-segment disease (ASD) is an increasingly problematic complication following lumbar fusion surgery. The purpose of the current study was to determine the risk of ASD requiring surgical treatment after short lumbar or lumbosacral fusion. Primary spinal disease and surgical factors associated with an increased risk of revision were also investigated. METHODS This was a retrospective cohort study using the French Spine Surgery Society clinical data that included 3338 patients, with an average follow-up duration of 7 years (range 4-10 years). Clinical ASD requiring surgery was the principal judgment criterion; the length of follow-up time and initial spinal disease were also recorded. Kaplan-Meier survival analysis was performed. The correlation between primary spinal disease and surgery with an increased risk of revision was investigated. RESULTS During the follow-up period, 186 patients required revision surgery for ASD (5.6%). The predicted risk of ASD requiring revision surgery was 1.7% (95% CI 1.3%-2.2%) at 2 years, 3.8% (95% CI 4.9%-6.7%) at 4 years, 5.7% (95% CI 4.9%-6.7%) at 6 years, and 9% (95% CI 8.7%-10.6%) at 8 years. Initial spinal disease affected the risk of ASD requiring surgery (p = 0.0003). The highest risk was observed for degenerative spondylolisthesis. CONCLUSIONS ASD requiring revision surgery was predicted in 5.6% of patients 7 years after index short lumbar spinal fusion in the French Spine Surgery Society retrospective series. An increased risk of ASD requiring revision surgery associated with initial spinal disease showed the significance of the influence of natural degenerative history on adjacent-segment pathology.

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

    Aim was to evaluate the dose distribution within the thyroid gland its association with hypothyroidism in breast cancer (BC) patients receiving supraclavicular (SC) radiation therapy (RT). Consecutive 40 BC patients with baseline normal thyroid function tests (TFTs), were randomized into two groups: (a) Adjuvant chest wall/breast with SC-RT (20 patients) and (b) control group (adjuvant chest wall/breast RT only); 20 patients. The thyroid gland was contoured for each patient. Each patient's dose volume histogram (DVH), mean thyroid volume, the volume percentages of the thyroid absorbing respectively 5, 10, 20, 30, 40, and 50 Gy (V5, V10, V20, V30, V40, and V50), and Dmean (average dose in whole volume of thyroid) were then estimated. TFTs were performed at the time of the last follow-up and compared. Mean thyroid volume of cohort was 19.6 cm(3) (4.02-93.52) and Dmean of thyroid gland in SC-RT and control group was 25.8 Gy (16.4-52.2) and 5.6 Gy (0.7-12.8), respectively. Median values of V5, V10, V20, V30, V40, and V50 were 54%, 51%, 42.8%, 30.8%, 27.8%, and 7.64%, respectively, in SC-RT as compared to control group (V5;4.9%, V10;2.4%, V20;1.75%, V301%, V40;0%, and V50;0%, respectively) with P thyroid function whereas four patients (10%) had hypothyroidism; 3/20 (15%) patients in SC-RT and 1/20 (5%) in control group with P thyroid volume (P = 0.03). The risk of hypothyroidism in BC patients after SC-RT depends on the thyroid gland volume and V30 >50% and the risk can be minimized by thyroid gland shielding during RT.

    Although metastases to the thyroid are never uncommon at autopsy in patients who died of malignancy, metastatic thyroid carcinomas are rarely detected in clinical practice in most cases and cases of secondary thyroid cancer which require thyroid surgery clinically are few. A clinical case of thyroid metastasis from renal cell carcinoma with thyroidectomy is described herein. An 87-year-old Japanese woman was referred to us for a slow-growing palpable neck tumor with dysphagia. She had undergone a nephrectomy for renal clear cell carcinoma 19 years earlier at another hospital. Preoperative imaging examinations suspected an adenomatous goiter and a fine needle aspiration (FNA) cytology was suggestive of an atypical follicular tumor. Hemithyroidectomy was performed as a follicular tumor of thyroid for restriction of subjective symptom. A pathological examination of the thyroid tumor revealed clear cell carcinoma, postoperatively. The negative result of immunohistochemical staining for thyroglobulin also suggested metastatic renal cell carcinoma to the thyroid. Clinically significant metastases to the thyroid gland are relatively infrequent. However, if patient who bears a thyroid tumor has a history of malignancy, the possibility of metastatic disease should be taken under consideration.

    Full Text Available Background: Primary hyperaparathyroidism (pHPT is often accompanied by underlying thyroid pathology that can confound preoperative parathyroid localization studies and complicate intra-operative decision making. The aim of this study was to examine the utility of preoperative thyroid ultrasonography (US in patients prior to undergoing parathyroidectomy for pHPT.Methods: An Institutional Review Board approved prospective study was undertaken from January 2005 through July 2008. All patients with pHPT meeting inclusion criteria (n=94 underwent preoperative thyroid ultrasound in addition to standard 99mTc-sestamibi scintigraphy for parathyroid localization. Demographics, operative management and final pathology were examined in all cases.Results: Fifty-four of the 94 patients (57% were noted to have a thyroid nodule on preoperative US, of which 30 (56% underwent further examination with fine needle aspiration biopsy. Alteration of the operative plan attributable to underlying thyroid pathology occurred in 16 patients (17%, with patients undergoing either total thyroidectomy (n=9 or thyroid lobectomy (n=7. Thyroid cancer was noted in 33% of patients undergoing thyroid resection, and 6% of all patients with HPT.Conclusions: The routine utilization of preoperative thyroid ultrasound in patients prior to undergoing parathyroid surgery for pHPT is indicated. The added information from this non-invasive modality facilitates timely management of co-incidental, and sometimes malignant, thyroid pathology.

    Thyroid eye disease (TED) has been found to reduce quality of life for many patients because of changes in their appearance and vision, although some seem to adjust better than others. This study was designed to investigate whether a patient's quality of life changes after having orbital decompression for improvement of appearance, vision, or both, and whether any demographic, clinical, or psychosocial factors can predict which patients might benefit from this surgery. This study used a within-subjects repeated-measures design, in which patients were assessed before and at 6 weeks and 6 months after surgery. A total of 123 adults (aged >18 years) with TED and undergoing orbital decompression surgery were recruited at Moorfields Eye Hospital. Participants received lateral wall, medial wall, 2.5 wall, or 3 wall decompression and were followed up after surgery with a range of psychosocial and clinical assessments. The Graves' Ophthalmopathy Quality of Life (GO-QOL) scale was completed at each time point, and this was used as the dependent variable in each hierarchical multiple regression model. Significant improvements were found in all clinical characteristics after orbital decompression and in most psychosocial variables. The GO-QOL visual function scores did not change significantly until 6 months after surgery. In contrast, GO-QOL appearance scores changed significantly by 6 weeks after surgery and continued to increase to 6 months, reaching a minimal clinically important difference for this scale. None of the changes in clinical or psychosocial outcomes significantly predicted change in GO-QOL visual function. However, the hierarchical regression model explained 79% of the variance in change in GO-QOL appearance, with change in subjective evaluation of appearance being the only unique predictor of change in appearance-related quality of life. This study highlights the importance of appearance-related cognitions in predicting quality of life outcomes after surgery

    Introduction: Warm ischemia and bleeding during laparoscopic partial nephrectomy place technical constraints on surgeons. Therefore it was the aim to develop a safe and effective laser assisted partial nephrectomy technique without need for ischemia. Patients and methods: A diode laser emitting light at 1318nm in cw mode was coupled into a bare fibre (core diameter 600 μm) thus able to transfer up to 100W to the tissue. After dry lab experience, a total of 8 patients suffering from kidney malformations underwent laparoscopic/retroperitoneoscopic partial nephrectomy. Clinically, postoperative renal function and serum c-reactive protein (CRP) were monitored. Laser induced coagulation depth and effects on resection margins were evaluated. Demographic, clinical and follow-up data are presented. Results: Overall interventions, the mean operative time was 116,5 minutes (range 60-175min) with mean blood loss of 238ml (range 50-600ml) while laser assisted resection of the kidney tissue took max 15min. After extirpation of the tumours all patients showed clinical favourable outcome during follow up period. The tumour size was measured to be 1.8 to 5cm. With respect to clinical safety and due to blood loos, two warm ischemia (19 and 24min) must be performed. Immediate postoperative serum creatinine and CRP were elevated within 0.1 to 0.6 mg/dl (mean 0.18 mg/dl) and 2.1-10 mg/dl (mean 6.24 mg/dl), respectively. The depth of the coagulation on the removed tissue ranged between <1 to 2mm without effect on histopathological evaluation of tumours or resection margin. As the surface of the remaining kidney surface was laser assisted coagulated after removal. The sealing of the surface was induced by a slightly larger coagulation margin, but could not measured so far. Conclusion: This prospective in-vivo feasibility study shows that 1318nm-diode laser assisted partial nephrectomy seems to be a safe and promising medical technique which could be provided either during open surgery

    Nowadays, in France, development of the ambulatory surgery has stalled. This is probably related to the fact that ambulatory surgery is restricted by the law to the "day surgery" in 12 hours, and only 17 procedures are referenced for this surgery. Thus, conventional hospitalization remained the rule after surgery. In January 2010, our university general surgery unit was restructured. It evolved from a conventional unit to a predominantly ambulatory unit. Otherwise, our unit adjoins a hotel, even inside our institution, which accommodates patients, patient visitors and tourists. The aim of this retrospective study was to compare the postoperative accommodation modalities between two groups of patients. The first group consisted of patients admitted before January 2010, at the time of conventional activity, whereas the second group consisted of patients admitted after January 2010 in a restructured unit. Inclusion of patients admitted from April 1, 2008 to March 31, 2009 (conventional hospitalization period) and from April 1, 2010 to March 31, 2011 (ambulatory management period), scheduled for one single surgical procedure excluding emergency. A total of 360 patients were retained: 229 for the conventional period and 131 for the ambulatory period, with a median age of 55 (range 15-87). No statistically significant difference was noted between the two groups as concerned median age, gender or ASA status. The number of postoperative nights varied significantly between the two groups with a mean of 3.8 nights (median three nights, range 0-32) for the conventional period versus 0.4 nights (median 0 night, range 0-10) for the ambulatory period (Plegal period of 12 hours to 24 hours in order to expand the list of the referenced procedures.

    Two standard particle transport codes of MCNP4C and integrated tiger series were used to estimate the total body dose in a thyroid cancer therapy study, with I-131 as the radionuclide source. Human body was modeled by water and soft tissue ellipsoids. Phantoms' dimensions were selected according to Brow nell recommendation. Absorbed fractions were calculated by both codes for different phantoms and for gammas with 0.364 MeV energy, which has the highest fraction in I-131 emitting gammas. Results were compared to the data published by Brow nell et.al.. Figure 1 shows the results of MCNP4C and Integrated Tiger Series with results published by Brow nell et. al.

    In vivo monitoring techniques consist of identification and quantification of radionuclides present in the whole body and specific organs and tissues. In Vivo monitoring requires the use of detedors which are sensitive to the radiation emitted by radionuclides present in the monitored individual. The results obtained in measurements may present small uncertainties which are within pre-set limits in monitoring programs for occupationally exposed individuais. However, any device used to determine physical quantities present uncertainties in the measured values. The total uncertainty of a measurement result is estimated from the propagation of the uncertainties associated to each parameter of the calculation. This study aims to evaluate the sources of uncertainty associated to the measurement results of in vivo monitoring of iodine 131 in the thyroid, in comparison to the suggested in the General Guide for Estimating Effective Doses from Monitoring Data (Project IDEAS/European Community). The reference values used were the ones for high-energy photons (>100 keV). The measurement uncertainties were divided into two categories: type A and type B. The component of type A represents the statistical fluctuation in the counting of the standard source. Regarding type B, the following variations were presented: detector positioning over the phantom; variation of background radiation; thickness of the overlay tissue over the monitored organ, distribution of the activity in the organ. Besides the parameters suggested by the IDEAS Guide, it has also been evaluated the fluctuation of the counting due to the phantom repositioning, which represents the reproducibility of the measurement geometry. Measurements were performed at the Whole Body Counter Unit of IRD using a scintillation detector Nal (Tl) 3 x3 and a neck-thyroid phantom developed at LABMIVIRD. Scattering factors were calculated and compared in different counting geometries. The results of this study show that the

    Aim: The aim of this study was to observe the findings of magnetic resonance spectroscopy of solitary thyroid nodules and its correlation with histopathology. Materials and methods: In this study, magnetic resonance spectroscopy was carried out on 26 patients having solitary thyroid nodules. Magnetic resonance spectroscopy (MRS) was performed on a 1.5 T super conductive system with gradient strength of 33 mTs. Fine needle aspiration cytology was done after MRS. All 26 patients underwent surgery either because of cytopathologically proven malignancy or because of cosmetic reasons. Findings of magnetic resonance spectroscopy were compared with histopathology of thyroid specimens. Results and conclusion: It was seen that presence or absence of choline peak correlates very well with presence or absence of malignant foci with in the nodule (sensitivity = 100%; specificity = 88.88%). These results indicate that magnetic resonance spectroscopy may prove to be an useful diagnostic modality for carcinoma thyroid.

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

    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.

    The adjuvant treatment by iodine 131 in good prognostic forms of differentiated thyroid cancers (DTC) makes not the object of a general consensus. There is no study demonstrating the benefit from such a treatment. Administration of an elevated iodine 131 activity and the constraint of a supplementary hospitalization are in these conditions questionable. In 6 patients, presenting the criteria of good prognostic and in post-operation, ambulatory conditions, administration of 19 mCi (703 MBc) of iodine 131 was done without previous administration of tracing dosage, followed after 72 hours by a whole-body scintigraphy, in the usual pause conditions. This administration was repeated 6 to 12 months later and followed by a new scintigraphic examination. The cervical fixation of iodine 131 was established qualitatively and quantitatively (as compared with a control zone). Five/six patients presented initially a cervical intense fixation with the star-like usual image and 1/6 patient a moderated fixation. Beginning with the second administration no cervical fixation was noted in 4/6 patients and a very low fixation in 2/6 patients. The concomitantly measured thyroglobulin, under simulation by TSH endogenous, was 131 I after quasi-total thyroidectomy in good-prognostic forms of DTC, without administration of previous tracing dosage to avoid possible phenomena of thyroid tissue blocking, allows probably, in overwhelming majority of cases, both a full or quasi-full destruction of the thyroid remnants and a severe reduction in the thyroglobulin rate measured in the conditions of pause of hormone-therapy

    1995-01-01

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

    Background: A rise in the incidence of thyroid cancer has been reported in several countries, and the increase is only seen in the papillary type. Increased detection due to higher resolution ultrasound and fine needle aspiration has been proposed as the explanation, recent registry studies however...... question this assumption. Methods: National, unselected, prospective cohort study of 1350 papillary thyroid cancer patients in Denmark from 1996 to 2008. Objective: To analyze changes in incidence by time and to identify factors which might influence detection rate. Results: A rise in incidence is seen...... thyroid surgery could not be confirmed. Conclusion: This study shows a significant rise in incidence of papillary thyroid carcinoma in Denmark from 1996 to 2008, which is not explained by increased use of preoperative diagnostic modalities. Other reasons need to be considered....

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

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

    INTRODUCTION: Basal cell carcinoma (BCC) is the most common malignant neoplasm with an annual incidence approaching 200/100,000 person-years. Mohs micrographic surgery (MMS) is widely used in North America and in Europe for treatment of BCC. This technique ensures radical tumour removal, sparing...... of the surrounding healthy skin, and it also offers higher cure rates than standard tumour excision with a predefined margin of healthy skin. The superiority of MMS relies on the fact that the entire (100%) margin of the excised tissue is examined microscopically for residual tumour in contrast to the traditional...... was 66.1 years. The most common localisations were the forehead (31.3%), the nose (31.0%) and the cheek (14.7%). Primary BCC comprised 54.0%; the remaining cases were relapses, most frequently after curettage (36.9%), radiotherapy (18.9%) and photodynamic therapy (11.7%). MMS leads to 40% smaller skin...

    We believe that routine axillary dissection for relatively early breast cancer should be reconsidered in view of the low incidence of lymph node metastasis and its effects on postoperative quality of life. We have performed bioptic lumpectomy to examine histological type, invasive tumor size, histological infiltration, and lymphatic invasion and have avoided axillary dissection in cases with a low risk of lymph node metastasis. In 126 cases of T0, T1a, or T2a breast cancers less than 3 cm in diameter in which axillary dissection was not performed, axillary recurrence was observed in 2 cases. Both patients underwent salvage procedures and are alive without disease. Furthermore, axillary recurrence was not observed in 23 cases treated with tangent irradiation and breast-preserving surgery. These findings suggest that axillary recurrence is possible in cases with previous indications for avoiding axillary dissection and that breast irradiation may prevent axillary recurrence. (author)

    Full Text Available Abstract Background Thyroid nodules represent a common problem brought to medical attention. Four to seven percent of the United States adult population (10–18 million people has a palpable thyroid nodule, however the majority (>95% of thyroid nodules are benign. While, fine needle aspiration remains the most cost effective and accurate diagnostic tool for thyroid nodules in current practice, over 20% of patients undergoing FNA of a thyroid nodule have indeterminate cytology (follicular neoplasm with associated malignancy risk prevalence of 20–30%. These patients require thyroid lobectomy/isthmusectomy purely for the purpose of attaining a definitive diagnosis. Given that the majority (70–80% of these patients have benign surgical pathology, thyroidectomy in these patients is conducted principally with diagnostic intent. Clinical models predictive of malignancy risk are needed to support treatment decisions in patients with thyroid nodules in order to reduce morbidity associated with unnecessary diagnostic surgery. Methods Data were analyzed from a completed prospective cohort trial conducted over a 4-year period involving 216 patients with thyroid nodules undergoing ultrasound (US, electrical impedance scanning (EIS and fine needle aspiration cytology (FNA prior to thyroidectomy. A Bayesian model was designed to predict malignancy in thyroid nodules based on multivariate dependence relationships between independent covariates. Ten-fold cross-validation was performed to estimate classifier error wherein the data set was randomized into ten separate and unique train and test sets consisting of a training set (90% of records and a test set (10% of records. A receiver-operating-characteristics (ROC curve of these predictions and area under the curve (AUC were calculated to determine model robustness for predicting malignancy in thyroid nodules. Results Thyroid nodule size, FNA cytology, US and EIS characteristics were highly predictive of

    Full Text Available Introduction: The incidence of thyroid cancer has been increasing in recent years. In this study, the clinical and laboratory findings of 14 patients with thyroid cancer were analysed retrospectively. They were admitted to our clinic with complaints of swelling of the neck. Methods: This study was performed in the Paediatric Endocrinology Polyclinics of Ataturk University Faculty of Medicine between 2008 and 2013. Patients with a diagnosis of thyroid cancer/hyperplasia were included. Patients’ age and gender, a family history of goitre and thyroid cancer, and exposure to radiation were elicited. Free thyroxine (T4, thyroid stimulating hormone, thyroglobulin and urinary iodine levels were measured. Ultrasonographic characteristics of nodules were determined. Fine-needle aspiration biopsy was performed if nodules were ≥ 10 mm in diameter. Results: The number of males and females was equal. There was no history of neck radiation. Grade 4 and grade 3 goitres were detected in four (28.5% and 10 (71.4% of 14 patients, respectively. The use of rock and iodized salt was determined in nine (64.2% and three (21.4% patients, respectively, while two (14.2% patients have been using both forms of salt. According to biopsy findings, benign thyroid tissue was present in three (21.4% patients, while papillary cancer, follicular carcinoma and hyperplasia were determined in six (42.8%, three (21.4% and five (35.7% patients, respectively. Conclusion: Even if the biopsy findings are normal, surgery must be done in the presence of a history of bleeding in a nodule, fixation of a nodule and cervical lymphadenopathy. Iodine deficiency is an important risk factor for thyroid cancer. People should be informed about iodine deficiency and iodized products should be provided to those who live in areas with endemic iodine deficiency.

    Recent developments have resulted in important changes in the diagnosis and management of thyroid diseases. Fine-needle aspiration biopsy has now supplanted imaging studies as the initial procedure for differentiating malignant from benign thyroid nodules. However, thyroid scintigraphy may be helpful in the management of patients without a definitive result of cytology and in Grave's disease with a nodule found in ultrasound scanning. On the other hand, scintigraphy remains critical for the determination of autonomously functioning tissue, and hyperthyroidism (over or subclinical) is an indisputable indication for scintigraphy in patients with a thyroid nodule. Besides, radionuclide scanning has retained its significance in the diagnosis of ectopic thyroid tissue, in the monitoring effects of radioiodine therapy, and in the evaluation of relapses in patients treated by surgery for benign thyroid diseases. The 131 I scintigraphy is commonly used in the postoperative follow-up of patients with the differentiated thyroid carcinoma, although the role of this procedure in management of the disease may change in the near future. Nowadays, the 123 I thyroid scintigraphy has been proposed as a safe and clinically important procedure for accurately counselling patients with congenital hypothyroidism. Moreover, the problem of underestimation of thyroid scintigraphy in diagnosis and management of benign diseases of gland in some regions of Poland has also been discussed. (author)

    The objective of the present study was the development of the diagnostic model for determining the human age based on the results of the comprehensive examination of the 230 thyroid cartilages (TC) obtained from the corpses of men and women of different age. TC were examined with the use of the anthropometric, X-ray, and histological methods. The anthropometric investigations confirmed the gender-related differences in the structure of human TC. Various characteristics of TC were shown to correlate with the age but these relationships were rather weak even if formally significant. The X-ray studies of TC have revealed the significant correlation of the relative amount of the bone tissue on the images with the age (r=0.8). Of the 27 parameters subjected to the morphometric evaluation, the following ones were shown to significantly correlates with the age: percentage of the bony (r=0,82) and cartilaginous (r=-0.8) tissue areas, average density of the adipose (r=0.76) and reticular (r=0.7) tissues, the maximum length of trabeculae (r=0.67), the width of the mature cartilage zone (r=0.54), the cortical plate thickness (r=0.5), and the mean number of immature chondrocytes in the field of vision (r=0.5). The comprehensive investigation into the structure of the human thyroid cartilage provided a basis for the development of the method for determining the human age with the use of the linear regression equations. It is concluded that the proposed method can be employed as an additional diagnostic tool for determining the human age for the purposes of forensic medical expertise and personality identification.

    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.

    Purpose: During general anesthesia, human body easily reaches a hypothermic state, which is mainly caused by heat redistribution. Most studies suggested that humidified heated breathing circuits (HHBC) have little influence on maintenance of the core temperature during early phase of anesthesia. This study was aimed at examining heat preservation effect with HHBC in case of undergoing surgery with less exposure of surgical fields and short surgical duration. Methods: Patients aged 19 to 70 yr - old, ASA-PS I or II who were scheduled for elective thyroidectomy were assigned and divided to the group using HHBC (G1) and the group using conventional circuit (G2) by random allocation. During operation, core, skin, and room temperatures were measured every 5minutes by specific thermometer. Results: G1 was decreased by a lesser extent than G2 in core temperature, apparently higher at 30 and 60 minutes after induction. Skin and room temperatures showed no differences between the two groups (p>0.05). Consequently, we confirmed HHBC efficiently prevented a decrease in core temperature during early period in small operation which has difficulty in preparing warming devices or environments were not usually considered. Conclusions: This study showed that HHBC influences heat redistribution in early period of operation and can lessen the magnitude of the decrease in core body temperature. Therefore, it can be applied efficiently for other active warming devices in mild hypothermia.

    The optimal surveillance strategy to screen for thyroid carcinoma childhood cancer survivors (CCS) at increased risk is still debated. In our clinical practice, beside neck palpation we routinely perform thyroid ultrasound (US). Here we describe the results obtained using this approach. We considered all CCS referred to our long term clinic from November 2001 to September 2014. One hundred and ninety-seven patients who had received radiation therapy involving the thyroid gland underwent US surveillance. Thyroid US started 5 years after radiotherapy and repeated every 3 years, if negative. Among 197 CCS previously irradiated to the thyroid gland, 74 patients (37.5%) developed thyroid nodules, and fine-needle aspiration was performed in 35. In 11 patients the cytological examination was suspicious or diagnostic for malignancy (TIR 4/5), whereas a follicular lesion was diagnosed in nine. Patients with TIR 4/5 cytology were operated and in all cases thyroid cancer diagnosis was confirmed. The nine patients with TIR 3 cytology also underwent surgery and a carcinoma was diagnosed in three of them. Prevalence of thyroid cancer was 7.1%. Tumour size ranged between 4 and 25 mm, but six (43%) were classified T3 because of extra-thyroidal extension. Six patients had nodal metastases; in eight patients the tumour was multifocal. At the time of the study all patients are disease free, without evidence of surgery complications. Applying our US surveillance protocol, the prevalence of radiation-induced thyroid cancer is high. Histological features of the thyroid cancers diagnosed in our cohort suggest that most of them were clinically relevant tumours. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Introduction: Fine-needle aspiration biopsy (FNAB) is the cornerstone of thyroid nodule evaluation. In most cases, FNAB can discriminate between benign and malignant disease. In other cases, it is only indicative of malignancy and the results are considered “suspicious”. In Denmark, thyroid FNAB...... results are categorised into six groups; “inadequate”, “cystic”, “inconclusive”, “benign”, “suspicious” and “malignant”. The risk of malignancy in the Danish “suspicious” group is of interest for patients as well as doctors participating in the diagnosis and treatment. The Danish Thyroid Surgery Database...... (THYKIR) registers preoperative thyroid FNAB and final histology. The aim of this study was to assess the malignancy risk among patients with a suspicious thyroid FNAB according to the Danish criteria and to identify possible predictors of malignant histology.

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

    Serum thyroglobulin (Tg) was measured by radioimmunoassay in 81 patients with thyroid tumor who were treated in the department of Internal medicine of National Medical Center from January, 1981 to June, 1982. The results were as follows: 1) The mean serum thyroglobulin level in thyroid tumor was significantly higher than normal subjects (p<0.001). 2) The mean serum thyroglobulin level in benign tumor was lower than malignant tumor (p<0.05). 3) The thyroid carcinoma with metastasis had significant high level of serum thyroglobulin than without metastasis (p<0.001). 4) The mean postoperative serum thyroglobulin level was significantly lower than preoperative level (p<0.001). Data from our study show that serum thyroglobulin determination is useful for assessing the presence of malignant thyroid tumor, metastasis and the extent of residual or recurrent thyroid cancer after surgery.

    Full Text Available Objective: To evaluate the cost-effectiveness of bariatric surgery in Italy from a third-party payer perspective over a medium-term (10 years and a long-term (lifetime horizon. Methods: A state-transition Markov model was developed, in which patients may experience surgery, post-surgery complications, diabetes mellitus type 2, cardiovascular diseases or die. Transition probabilities, costs, and utilities were obtained from the Italian and international literature. Three types of surgeries were considered: gastric bypass, sleeve gastrectomy, and adjustable gastric banding. A base-case analysis was performed for the population, the characteristics of which were obtained from surgery candidates in Italy. Results: In the base-case analysis, over 10 years, bariatric surgery led to cost increment of EUR 2,661 and generated additional 1.1 quality-adjusted life years (QALYs. Over a lifetime, surgery led to savings of EUR 8,649, additional 0.5 life years and 3.2 QALYs. Bariatric surgery was cost-effective at 10 years with an incremental cost-effectiveness ratio of EUR 2,412/QALY and dominant over conservative management over a lifetime. Conclusion: In a comprehensive decision analytic model, a current mix of surgical methods for bariatric surgery was cost-effective at 10 years and cost-saving over the lifetime of the Italian patient cohort considered in this analysis.

  8. Thyroid evaluation with radioassay

    International Nuclear Information System (INIS)

    1983-01-01

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

    {sup 131}I therapy is regularly used following surgery as a part of thyroid cancer management. Despite an overall relatively good prognosis, recurrent or metastatic thyroid cancer is not rare. CD133-expressing cells have been shown to mark thyroid cancer stem cells that possess the characteristics of stem cells and have the ability to initiate tumours. However, no studies have addressed the influence of CD133-expressing cells on radioiodide therapy of the thyroid cancer. The aim of this study was to investigate whether CD133{sup +} cells contribute to the radioresistance of thyroid cancer and thus potentiate future recurrence and metastasis. Thyroid cancer cell lines were analysed for CD133 expression, radiosensitivity and gene expression. The anaplastic thyroid cancer cell line ARO showed a higher percentage of CD133{sup +} cells and higher radioresistance. After {gamma}-irradiation of the cells, the CD133{sup +} population was enriched due to the higher apoptotic rate of CD133{sup -} cells. In vivo {sup 131}I treatment of ARO tumour resulted in an elevated expression of CD133, Oct4, Nanog, Lin28 and Glut1 genes. After isolation, CD133{sup +} cells exhibited higher radioresistance and higher expression of Oct4, Nanog, Sox2, Lin28 and Glut1 in the cell line or primarily cultured papillary thyroid cancer cells, and lower expression of various thyroid-specific genes, namely NIS, Tg, TPO, TSHR, TTF1 and Pax8. This study demonstrates the existence of CD133-expressing thyroid cancer cells which show a higher radioresistance and are in an undifferentiated status. These cells possess a greater potential to survive radiotherapy and may contribute to the recurrence of thyroid cancer. A future therapeutic approach for radioresistant thyroid cancer may focus on the selective eradication of CD133{sup +} cells. (orig.)

    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.)

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

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

    For the 24 years passed after the Chernobyl catastrophe a significant experience in estimation of medical consequences of thyroid irradiation among Belarus patients had been accumulated. The aim of our screening of ultrasonic examination was the detection of the thyroid hypoplasia prevalence in the regions affected with radionuclide fallout. Since 2004 to 2007 thyroid ultrasound with volume estimation was performed in 3311 Belarus subjects, living on the areas of Brest region with the different contamination rate density. Examined subjects were divided in 3 groups: 1) irradiated at the age of 1 to 3 years old at the moment of Chernobyl catastrophe, 2) irradiated in utero, and 3) born after the catastrophe. It was revealed that thyroid hypoplasia was detected in 3% of group 1 (out of 1876 persons), in 5, 8% of group 2 (out of 503 persons, P<0.05) and in 1, 7% of the third group (out of 932 persons). The separation of the irradiated in utero subjects (group 2) to subgroups in dependence of the gestation period, showed the highest prevalence of thyroid hypoplasia among the irradiated in the first trimester of gestation: 7, 7% (P<0.05), in the second trimester: 5, 3%, in the third trimester: 4, 7%

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

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

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

    Full Text Available Introduction Completion thyroidectomy is defined as the surgical removal of the remnant thyroid tissue following procedures of less than total or near-total thyroidectomy. Whether thyroid reoperations are associated with an increased complication risk is controversial. Objective A retrospective analysis was done of patients undergoing completion thyroidectomy for cancer of the thyroid who had undergone surgery elsewhere for solitary thyroid nodule. The incidence of surgical complications in these patients after reoperation was investigated in this study. Material and methods The study included a total of 53 patients who had undergone thyroid lobectomy for a solitary nodule as initial surgery elsewhere and were referred to our institute for completion thyroidectomy when the histopathology revealed malignancy. Results There were 53 patients, 43 females and 10 males. Their mean age was 34.7±12.12 years (range 19–65 years. After initial surgery, the histopathology revealed papillary carcinoma in 46 patients (86.8%, follicular carcinoma in 7 (13.2%. Fourteen out of 53 patients had recurrent laryngeal nerve palsy after initial surgery (26.4%. None of the patients had clinical hypocalcemia after the first surgery. One or more parathyroid glands were identified and preserved in 52 patients (98.1% in the process of completion thyroidectomy. No patient had additional recurrent nerve injury at the second surgery. The mean serum calcium value preoperatively was 8.96±0.39 mg/dL, and six months after surgery serum calcium was 8.74±0.56 mg/dL. Mean follow-up was 18 months. Transient hypoparathyroidism occurred in 24.5% patients. Five patients were lost to follow-up. Permanent and symptomatic hyperparathyroidism occurred in eight patients (16.67%. Conclusions Completion thyroidectomy is a safe and appropriate option in the management of well-differentiated thyroid cancer. It removes disease on the ipsilateral and contralateral side of the thyroid and

    Background: Sonographic size of suspicious thyroid lesions is an essential parameter in the evaluation of thyroid nodules, determining the need for needle biopsy and has impact on the extent of surgery. Limited data is available on the correlation between the size of the thyroid nodule on sonography and the actual size measured during histological examination. The aim of the present study was to compare these two modalities and to discuss the potential clinical implications of the findings in the study population. Methods: The database of Rabin Medical Center was reviewed for all patients with histologically proven papillary carcinoma of the thyroid treated by thyroid surgery between 2005 and 2010. Results: 292 patients with papillary thyroid carcinoma were included. The mean sonographic size of the nodule was 2.19 ± 1.15 cm. The mean pathological diameter was 1.69 ± 1.09 cm. Discrepancies between tumor histological diameter and the sonographically measurement were more prominent in tumors larger than 1.5 cm. Nonetheless, 18.8% of thyroid nodules that were measured by US as larger than 1 cm, were found to be smaller than 1 cm on final pathology. Similarly, 7.2% of nodules evaluated by sonography were determined as being larger than 4 cm, while their definitive size was smaller than 4 cm. Conclusions: We noted a significant discrepancy between the preoperative sonographic and the pathologic size measurements for papillary thyroid carcinoma. The sonographic evaluation misclassifies both patients with small and large thyroid tumors, and consequently exposes them to unnecessary workup and more extensive operation. This discrepancy between the ultrasound findings and actual tumor size should be taken into account in clinical practice and help guide the evaluation and treatment of patients with thyroid nodules.

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

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

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

    Objectives: Virtual Touch tissue quantification (VTQ) is a quantified ultrasound (US) acoustic radiation force impulse (ARFI) imaging method that provides numerical measurements (wave-velocity values) of tissue stiffness. The purpose of this study was to detect whether VTQ could be applied to differentiate between benign and malignant thyroid lesions. Methods: Healthy subjects’ thyroid tissue and thyroid lesions were examined by VTQ to analyze their elasticity after conventional ultrasound. All the thyroid lesions were analyzed pathologically after surgery and correlated the VTQ values with the pathological results. Results: The VTQ value of healthy thyroid tissue, the benign lesions, and the malignant lesions were 1.69 ± 0.41 m/s, 2.03 ± 0.42 m/s, and 3.10 ± 1.08 m/s, respectively. The VTQ value of the malignant lesions was higher than that of the healthy thyroid tissue and the benign lesions (both p < 0.001). The VTQ value of the benign lesions was higher than that of the healthy thyroid tissue (p < 0.001). With a cutoff value of 2.42 m/s, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for differentiating between the benign and the malignancy lesions were 80.00%, 89.23%, 87.05%, 69.56%, and 93.54%, respectively. Conclusions: VTQ could provide quantitative elasticity measurements, which might play an important role in differentiating between benign and malignant thyroid lesions

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

  9. Selenomethionine scintigraphy in the diagnosis of cold thyroid nodules

    1976-01-01

    This work attempts to establish the value of a tumoral radiotracer for thyroid exploration: 75 Se-labelled methionine. The purpose of such a radioelement for US in scintigraphy is to allow the cold thyroid nodule diagnosis to be established before surgery, the extent of which depends on whether the nodule is benign or malignant. After a survey of present thyroid cancer diagnosis methods the different tumoral radiotracers are reviewed especially those used to diagnose thyroid neoformations. Selenomethionine appears as one of the most universal of these radiotracers since methionine is an essential amino acid involved in protein synthesis, which is accelerated inside tumour cells, while selenium itself in the form of certain salts possesses a known tropism for neoplastic tissues. The original feature of our study is the use of a method attempting to optimise the results by a more objective reading of the images. To this end we employed a scintillation camera for image acquisition and a data processing system to perform an electronic subtraction, on the thyroid image obtained with selenomethionine, of the thyroid image supplied by radioiodine. The method is nevertheless limited by the properties of the radiotracer used: its long physical and biological half-life is a contra-indication in patients under forty, the dose received by the gonads being relatively large [fr

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

    Radioguided surgery is a minimally invasive surgical technique for the treatment of primary hyperparathyroidism. The goals of our study were to evaluate the rate of success and compare the results with intraoperative histological analysis. We retrospectively studied 84 patients with primary parathyroidism who had undergone radioguided surgery. All the patients had a positive parathyroid scintigraphy prior to surgery. An intravenous injection of Tc-99m sestamibi was administered before surgery, and radioguided location of the pathologic parathyroid tissue was performed using an intraoperative gamma probe, applying the "20% rule". All resected specimens underwent intraoperative histologic analysis. All patients were followed up for at least 6 months. Positive predictive values of both parathyroid scintigraphy and cervical ultrasonography were also compared. Radioguided surgery success rate was 99%. Sensitivity, specificity, positive and negative predictive values for gamma probe were 99, 73, 97 and 89%, respectively. After surgery, 83 of 84 patients were eucalcaemic (99%) and parathyroid hormone normalised in 77 of 84 patients (92%). Ultrasonography showed low positive predictive value (41%) when compared with scintigraphy. Radioguided surgery is a minimally invasive surgical technique with excellent results for the treatment of primary hyperparathyroidism and could replace both intraoperative histological analysis and intraoperative parathyroid hormone assay. Further studies are needed to confirm these findings. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello. All rights reserved.

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

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

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

    Purpose: The incidence of hypothyroidism after radiation therapy for head and neck cancer (HNC) has been found to be ≤53%. Medical treatment of hypothyroidism can be costly and difficult to titrate. The aim of the present study was to assess the feasibility of free thyroid transfer as a strategy for the prevention of radiation-induced damage to the thyroid gland during radiation therapy for HNC. Methods and Materials: A prospective feasibility study was performed involving 10 patients with a new diagnosis of advanced HNC undergoing ablative surgery, radial forearm free-tissue transfer reconstruction, and postoperative adjuvant radiation therapy. During the neck dissection, hemithyroid dissection was completed with preservation of the thyroid arterial and venous supply for implantation into the donor forearm site. All patients underwent a diagnostic thyroid technetium scan 6 weeks and 12 months postoperatively to examine the functional integrity of the transferred thyroid tissue. Results: Free thyroid transfer was executed in 9 of the 10 recruited patients with advanced HNC. The postoperative technetium scans demonstrated strong uptake of technetium at the forearm donor site at 6 weeks and 12 months for all 9 of the transplanted patients. Conclusions: The thyroid gland can be transferred as a microvascular free transfer with maintenance of function. This technique could represent a novel strategy for maintenance of thyroid function after head and neck irradiation.

    Full Text Available Background. Mediastinal lymph node metastases (MLNM have not been extensively studied. The aim of this study is to investigate the characteristics, predictive factors, and prognosis of MLNM in thyroid cancer. Methods. This is a retrospective study based on the thyroid cancer patients with MLNM at our institution from 2008 to 2015. Results. In total, 73 thyroid cancer patients with positive MLNM were included in this study. It contained sixty patients (82.2% with papillary thyroid carcinoma (PTC, twelve (16.4% with medullary thyroid carcinoma, and one (1.4% with anaplastic thyroid carcinoma. Forty-eight patients had the surgery as initial treatment. Fifty-three (72.6% patients remained disease-free, and fifteen (20.5% developed a regional recurrence. Distant metastases occurred in four (5.5% patients and five (6.8% patients died. Five-year overall survival rate and disease-free survival (DFS rate of the PTC patients for initial treatment are 95.4% and 77.2%, respectively. Extrathyroidal extension and multiple lymph nodes involved were associated with DFS in PTC patients. Conclusions. Initial therapeutic control is very important for the thyroid cancer patients. Extrathyroidal extension and multiple mediastinal lymph nodes involved were the influence factors of prognosis in the thyroid cancer patients with MLNM.

All patients underwent a diagnostic thyroid technetium scan 6 weeks and 12 months postoperatively to examine the functional integrity of the transferred thyroid tissue. Results: Free thyroid transfer was executed in 9 of the 10 recruited patients with advanced HNC. The postoperative technetium scans demonstrated strong uptake of technetium at the forearm donor site at 6 weeks and 12 months for all 9 of the transplanted patients. Conclusions: The thyroid gland can be transferred as a microvascular free transfer with maintenance of function. This technique could represent a novel strategy for maintenance of thyroid function after head and neck irradiation.

    To evaluate the 1-year results of corneal collagen cross-linking (CXL) in eyes with postoperative excimer laser refractive surgery corneal ectasia. Thirteen eyes of 9 consecutive patients who had undergone excimer laser refractive surgery (photorefractive keratectomy [n = 3], LASIK [n = 10]) with resultant unstable corneal ectasia underwent CXL with photosensitizing riboflavin 0.1% solution and subsequent exposure to ultraviolet radiation. Study eyes underwent complete ophthalmologic examination, endothelial specular microscopy, corneal topography, and aberrometry as well as central pachymetry and Scheimpflug-based topo/tomography preoperatively and at 3-, 6-, and 12-month intervals. Best spectacle-corrected visual acuity (BSCVA) improvement was statistically significant (P corneal thickness at 0 and 2 mm from the thinnest corneal point decreased significantly. One year after surgery, CXL appears to stabilize eyes with ectasia consequent to excimer laser refractive surgery and improve BSCVA.

    2009-08-01

    Full Text Available Thyroid associated ophthalmopathy is an autoimmune disorder affecting the orbital and periorbital tissues. Hyperthyroidism is commonly associated with thyroid associated ophthalmopathy, however in 5% to 10% of cases it is euthyroid. Genetic, environmental and endogenous factors play a role in the initiation of the thyroid ophthalmopathy. Smoking has been identified as the strongest risk factor for the development of the disorder. The pathogenesis involves activation of both humoral and cell mediated immunity with subsequent production of gycoaminoglycans, hyaluronic acid resulting in oedema formation, increase extraocular mass and adipogenesis in the orbit. The natural history of the disease progresses from active to inactive fibrotic stage over a period of years. Diagnosis is mainly clinical and almost all patients with ophthalmopathy exhibit some form of thyroid abnormality on further testing. Treatment is based on the clinical severity of the disease. Non-severe cases are managed by supportive measures to reduce the symptomatology and severe cases are treated by either medical or surgical decompression. Rehabilitative surgery is done for quiescent disease to reduce diplopia and improve cosmesis.

    In order to know how thyroid nodules and differentiated thyroid cancers are investigated and treated in 1988, an international inquiry was performed by mean of a questionnaire based on a well-defined case report of a 35-year-old female with a solitary small thyroid nodule. Clinicians were asked to indicate their diagnostic and therapeutic approaches to the reported case and to some variations. Analysis of the 157 responses from thyroid experts showed that three in vitro tests (sensitive-TSH, free T 4 and total T 4 ) and three in vivo tests ( 99m Tc or radioiodide scintiscan, fine needle aspiration and ultrasonography) were performed most frequently. In the case of a solid and cold nodule and in the absence of fine needle aspiration results, 19% of respondents advocated suppressive therapy and 81% surgery. In the same clinical case, but whom fine needle aspiration had been performed and cytology was benign, surgery was advocated by 24%, suppressive therapy by 48% and a regular follow-up without treatment by 28% of respondents. When surgery was performed and the diagnosis was a differentiated thyroid cancer, (near) total thyroidectomy was more frequently chosen than partial thyroidectomy in both papillary (60 and 40%, respectively, of respondents) and follicular (74 and 26%, respectively, of respondents) cancers; 80% of clinicians did not change their surgical technique in relation to histological type of the tumour. Total thyroidectomy was more often recommended in most of the clinical or anatomical variations compared with the basic case repot. Pre- og postoperative hormonal therapy was initiated with L-T 4 and TSH suppression was controlled by sensitive-TSH and thyroblobulin determinations. After total thyroidectomy, 131 I was used with similar modalities for papillary and follicular cancers to ablate a thyroid remnant. (author)

    Patient-reported outcome measures reveal the quality of surgical care from the patient's perspective. We aimed to compare body image, self-esteem, hospital anxiety and depression, and cosmetic outcomes by using validated tools between patients undergoing robot-assisted surgery and those undergoing conventional open surgery. This single-center, multidisciplinary, randomized, prospective study of 62 patients who underwent cardiac surgery was conducted at Hospital from May 2013 to January 2015. The patients were divided into two groups: the robotic group (n = 33) and the open group (n = 29). The study employed five different tools to assess body image, self-esteem, and overall patient-rated scar satisfaction. There were statistically significant differences between the groups in terms of self-esteem scores (p = 0.038), body image scores (p = 0.026), overall Observer Scar Assessment Scale (p = 0.013), and overall Patient Scar Assessment Scale (p = 0.036) scores in favor of the robotic group during the postoperative period. Robot-assisted surgery protected the patient's body image and self-esteem, while conventional open surgery decreased these levels but without causing pathologies. Preoperative depression and anxiety level was reduced by both robot-assisted surgery and conventional open surgery. The groups did not significantly differ on Patient Satisfaction Scores and depression/anxiety scores. The results of this study clearly demonstrated that a minimally invasive approach using robotic-assisted surgery has advantages in terms of body image, self-esteem, and cosmetic outcomes over the conventional approach in patients undergoing cardiac surgery.

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

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

    Crohn's disease is an inflammatory bowel disease which may affect different parts of the gastrointestinal tract. To compare retrospectively the results of laparotomy and laparoscopic surgery performed in patients with Crohn's disease between January 1, 2005 and October 31, 2012 in the Department of Surgery, University of Szeged, Hungary. Patients were divided into two groups based on the types of surgery; 103 patients underwent laparotomy and 30 patients had laparoscopic surgery programmed. 22 patients had 24 primary acute interventions. The mean age was significantly lower in the laparoscopic surgery group (p = 0.042). The laparoscopic ileocecal resections have been found significantly shorter than laparotomies (p = 0.033). When ileocecal resection was performed the operation time was significantly longer (p = 0.033) while hospitalization time (p = 0.025) and intensive care unit treatment time (plaparotomy group. Laparoscopic surgery results in smaller surgical trauma, better cosmetic outcome, shorter hospitalization time and not higher complication- and morbidity-rate as well as shorter operation time in certain cases. However, it requires more qualified surgical team and the operation expenses are higher.

  6. Results of single-event multilevel orthopedic surgery in children with cerebral palsy

    Full Text Available Background: Single-event multilevel orthopedic surgery is a modern approach in the operative treatment of children with cerebral palsy. Methods: Single-event multilevel orthopedic surgery was carried out in 108 patients with cerebral palsy. Patients’ average age was 11.3±1.7 years. Surgical results were analyzed at follow-up after 18 to 24 months, by way of detailed physical examination, functional assessment, imaging, the Edinburgh Visual Gait Score and Gillette Functional Assessment Questionnaire. Results: In our series, 647 procedures were performed during 141 surgeries. Patients had an average of 4.59 procedures per surgery. Observational gait analysis showed an improvement in stance and swing gait phases in ambulatory children. According to the Gillette Functional Assessment Questionnaire, an increase of functional level was noted in 50 patients but did not change in 32 patients. Conclusions: For children with cerebral palsy, single-event multilevel surgery is defined as two or more surgical procedures of the soft tissue or bone at two or more anatomical levels during one operative procedure. In cases where a large volume of surgery is required, two separate operations with a short break in between, but requiring only one hospital admission and one rehabilitation period, are also included. This approach requires adapted methods of surgical intervention, and appropriate methods of anesthesia and pain control in the postoperative period to the start of rehabilitation. Compliance with the above principles allowed the necessary correction of orthopedic complications to be achieved in all cases.

    GERD reduces social activity and significantly affects the quality of life (QOL) of patients and the risk of complications (cancer of the esophagus, esophageal-gastric bleeding, strictures, perforation) is one of the most pressing problems of medicine of XXI century. The aim of the research is to evaluate the results of videolaparoscopic fundoplication at five years after surgery in patients with gastroesophageal reflux disease. We studied results of videolaparoscopic antireflux surgery (VLAS) during 2009-2016 years in Department of Surgery and Endoscopy Faculty of postgraduate medical education Lviv National Medical University. We have gathered the group of 195 patients who underwent VLAS. Among the complications of GERD, Barrett's esophagus was diagnosed in 9 (19.6 %), peptic ulcer of the esophagus in 10 (21.7 %), peptic stricture of the esophagus in 4 (8.7 %), esophageal-gastric bleeding in 23 (50.0 %) patients, including Malory-Weiss syndrome in 18, erosive ulcerous bleeding in 5 people. In 176 (90.2 %) patients completed Nissen fundoplication, in 14 (7.2 %) - Toupe, 5 (2.6 %) - Dor fundoplication. We use standart surgical techniques. The mean operative time was 95±25,2 minutes. In 2 patients after surgery capnothorax on left side had occurred and treated. The mean hospital stay was 3±2,4 days. There were no serious complications in the time of surgery and after it, as well as no conversions or repeated antireflux surgeries at five years after surgery. Videolaparoscopic antireflux surgery for GERD is an equally effective alternative to medical therapy and should be offered to appropriately selected patients by skilled surgeons.

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

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

    The reasons why some patients who begin the presurgical process for bariatric surgery fail to complete the procedure are understudied. Previous research implies that psychological factors play a role. To examine whether scores from baseline psychological testing incrementally predict failure to proceed with bariatric surgery beyond demographic information in patients' medical charts and data derived from a clinical interview. Cleveland Clinic Bariatric and Metabolic Institute. The sample (n = 1160) was mainly female (72.41%), middle aged (mean age = 46.07 yr, SD = 11.70) and of Caucasian descent (65.76%). Hierarchical logistic regressions were conducted to test the incremental validity of baseline Minnesota Multiphasic Personality Inventory-2 Restructured Form scores after controlling for information gathered from the psychological interview and medical charts. Relative risk ratios were calculated to reflect the clinical utility of the results. In total, 27.16% of patients failed to proceed with bariatric surgery after 1 year or more after a recommendation for surgery from their psychological evaluations. Psychological test scores were substantially associated with failure to proceed with surgery and significantly accounted for up to 6% of additional variance after controlling for psychological interview variables and medical chart data. Elevated scores on Minnesota Multiphasic Personality Inventory-2 Restructured Form scales, such as anxiety and substance use, identify patients at up to 2.5 times greater risk for failing to proceed with bariatric surgery. Objective psychological test data-notably, scale scores assessing for substance abuse, anxiety, and demoralization-add to information obtained from a clinical interview and medical records in identifying patients at risk for failing to proceed with bariatric surgery.

    The purpose of this study was to investigate the association between chronic lymphocytic thyroiditis (CLT) and malignant tumors of the thyroid. A retrospective review of 647 patients who underwent thyroid surgery at the Department of Breast and Thyroid Surgery in Anhui Provincial Hospital, China in 2012 was performed. The clinicopathological characteristics of patients with thyroid malignancies and CLT were collected. CLT was diagnosed by histopathological method. Among 647 patients, 144 patients had thyroid malignancies and 108 patients had been diagnosed with CLT. Moreover, in total, 44 patients had thyroid malignancies coexistent with CLT: forty-one (93.2%) patients had been diagnosed with the papillary thyroid cancer (PTC); two (4.5%) patients suffered from medullary carcinoma; and one (2.3%) patient suffered from lymphoma. The morbidity of thyroid malignancies in patients with CLT was significantly higher than that in patients without CLT (40.7% versus 18.6%; P CLT compared with those without CLT (P CLT and without CLT. Female predominance was observed in patients with CLT. CLT may have no effect on the progression of thyroid malignant tumor. Nevertheless, the influences of CLT on the prognosis of the thyroid carcinoma still need to be investigated with a larger sample size.

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

    Novenario, H.S.; Pascacio, F.M.; Cruz, Benjamin de la; Anden, A.B.

    Whole body counters are not only used in measuring radioactivity in the body for radiation protection purposes but also in the measurement of iron absorption, body potassium and cesium, chronic blood loss, and also in the determination of the effectiveness of surgery, thyroid hormone and radioactive iodine therapy in thyroid carcinoma. This report deals with our experience in the use of a shadow-shield whole body counter in the determination of I-131 uptake by metastatic lesions of cancer of thyroid after total thyroidectomy and ablation therapy with I-131. This study was undertaken jointly by the Department of Nuclear Medicine, Veterans Memorial Hospital and the Biomedical Research Division of the Philippine Atomic Energy Commission. Preliminary results indicate that the 22 patients who underwent whole body counting after total thyroidectomy I-131 ablation therapy, 9 patients had elevated percentage retention of I-131, 10 patients with normal values and 3 patients with rising values. Foci of I-131 concentration in those with elevated and rising percentage concentration values were seen in the thyroidal bed scintiscans, while the 10 patients with normal values had negative scintiscans. The results of our observations confirm the results obtained by other workers abroad. Our preliminary results indicate that with the use of whole body counters a sensitive method of assessing whether functioning metastatic lesion of cancer of the thyroid still exist after total thyroidectomy and I-131 ablation therapy can be provided.

    Although recent evidence has implicated viruses in the regulation of epithelial-to-mesenchymal transition and tumor progression, little is known regarding viral infections in thyroid malignancies. Thus the aim of this study was to detect sequences of 3 potentially oncogenic viruses - BK virus (BKV), Epstein-Barr virus (EBV) and human papillomavirus (HPV) - in a series of postoperative thyroid gland specimens. Thirty patients with thyroid nodules who underwent surgery for thyroid disease within a 3-year period were enrolled. Both nodular and adjacent normal thyroid tissue was surgically excised from each patient. Viral gene sequences of BKV (VP1), EBV (LMP1, EBNA2 and EBER1) and HPV were amplified by PCR. The PCR results were confirmed by direct sequencing analysis. VP1 gene sequences were detected in 60% (18/30) of thyroid cancer or multinodular hyperplasia lesions compared with in 43.3% (13/30) of adjacent normal thyroid tissue specimens. Fifteen of thirty (50%) of thyroid cancer or multinodular hyperplasia samples revealed LMP1 sequences compared with 46.7% (14/30) of corresponding normal thyroid tissues. EBNA2 gene sequences were detected in 90% (27/30) of thyroid cancer or multinodular hyperplasia samples, compared with 90% (27/30) of adjacent normal thyroid tissue specimens. All samples were negative for EBER1 sequences, while HPV DNA was not detected in either nodular or normal thyroid tissue. This study suggests that BKV and EBV "infection" is an early event, occurring within normal tissue. Our findings do not show a clear role for the viruses examined, instead they suggest an "endemicity" pattern rather than a causal effect.

    The purpose of this study was to analyze the results of the combined modality treatment and radiation therapy using 6.3 MeV fast neutrons c. The study included 45 patients with thyroid gland cancers who received the combined modality treatment and radiation therapy alone with the use of 6.3 MeV fast neutrons generated within U-120 cyclotron. The clinical trial of neutron-photon therapy used alone and in combination with the surgery for the patients with aggressive forms of thyroid cancer showed feasibility of increasing the effectiveness of treatment due to the reduction in the incidence of local recurrences. In addition, satisfactory treatment tolerance and absence of severe specific complications dictate the necessity of prospective studies to improve treatment outcomes.

  18. Treatment of well-differentiated thyroid carcinoma

    Improved selection of thyroid nodules for surgery and greater individualization of surgery for well-differentiated thyroid carcinoma are emphasized. Thyroid nodules are common but infrequently are manifestations of carcinoma. Needle biopsy permits better selection of patients with thyroid nodules for surgery by identifying those which are malignant or are likely to become malignant. Experience in performing diagnostic needle biopsies and in cytologic and histologic interpretation is essential. The majority of well-differentiated thyroid carcinomas are well-localized papillary carcinomas controlled by surgery, usually a lobectomy or partial thyroidectomy. Well-differentiated thyroid carcinomas include papillary and follicular types and their subsets. The extent of surgery should be individualized based on gross extent of disease, histologic variety, and age of the patient. The prognosis is reduced for patients more than 40 years of age. With appropriate early surgical treatment, the outlook is excellent. Metastatic disease can frequently also be controlled by large doses of thyroid hormone and the use of radioactive iodine

  19. Clinical Experiences with Radiation Induced Thyroid Cancer after Chernobyl

    Full Text Available The risk of developing thyroid cancer increases considerably after exposure to external or internal radiation, especially in children below the age of 10. After the Chernobyl reactor accident, the yearly incidence of childhood thyroid cancer in Belarus increased to approximately 40 per 1.000.000 in girls and to roughly 20 per 1.000.000 in boys compared to approximately 0.5 cases per 1.000.000 prior to the accident. Typically, young children with thyroid cancer after radiation exposure present in ≈95% of the cases as papillary cancers, in ≈50% as invasive tumors growing outside the thyroid capsule, in ≈65% with lymph node metastases and in ≈15% with distant metastases. A joint Belarusian-German project starting in April 1993 that combined treatment with surgery and radioiodine was organized in 237 selected children from Belarus who were exposed to the Chernobyl fallout and had advanced stages of thyroid cancer. The study group included 141 girls and 96 boys. Their median age at the time of the accident was 1.7 years; whereas the median age at the time of diagnosis was 12.4 years. With the exception of two cases with follicular histology, the majority of the patients had been diagnosed with papillary thyroid cancers. In 63%, the tumor had grown outside the thyroid capsule and invaded the tissue of the neck (pT4. Nearly all of the selected cases (96% showed-up with lymph node metastases (pN1 and 43% of the patients with distant metastases mainly to the lungs (pM1. In 58% of the children, complete remissions of thyroid cancer could be achieved until December 31st 2010 and in 34% of the children, stable partial remissions; in the remaining 8% of the patients, partial remissions were observed. The risk of radiation-induced thyroid cancer increased considerably in children and adolescents who were affected by the Chernobyl reactor accident. In spite of the fact, that thyroid cancers in young children seem to behave more aggressively than in

    Historically, thyroid surgery has been fraught with complications. Injury to the recurrent laryngeal nerve, superior laryngeal nerve, or the parathyroid glands may result in profound life-long consequences for the patient. To minimize the morbidity of the operation, a surgeon must have an in-depth understanding of the anatomy of the thyroid and parathyroid glands and be able to apply this information to perform a safe and effective operation. This article will review the pertinent anatomy and embryology of the thyroid and parathyroid glands and the critical structures that lie in their proximity. This information should aid the surgeon in appropriate identification and preservation of the function of these structures and to avoid the pitfalls of the operation.

    We compared the incidence of insufficient thyroid cytology due to blood-stained materials or low cellularity in terms of aspiration technique, especially focusing on the degree of suction pressure and needle size. Three experienced radiologists performed ultrasound-guided aspiration for thyroid nodules in 1174 thyroid nodules consecutively. Three different techniques were used; (A) using a 25 gauge needle with mainly capillary technique in 269 nodules; (B) using a 25 gauge needle with 3 cc syringe and minimal suction pressure in 303 nodules; (C) using a 22-23 gauge needle with 10 cc syringe and aspirator in 602 nodules. The differences of the incidence of the insufficient cytology among the three aspiration techniques and relationships of the incidence and needle size/degree of suction pressure was statistically analyzed using the Mann-Whitney U test and the chi-square test with linear-by-linear association. Overall, the difference in insufficient cytology was significant across the three aspiration technique (p = 0.004), and the incidence tended to increase significantly with increase of needle size and degree of suction pressure (p < 0.001). A pairwise comparison of aspiration techniques found significant differences (p = 0.003) between techniques (A) and (C), and no differences between technique (B) and (C) (p 0.07) and between techniques (A) and (B) (p = 0.10). The incidence of insufficient cytology was significantly low in the capillary technique, and it increased significantly with the increase of needle size and degree of suction pressure.

    Primary mucinous carcinoma of the thyroid gland is a rare disease; only 6 cases of primary mucinous carcinoma of the thyroid have been previously reported. Primary mucinous carcinoma of the thyroid gland with incomplete tumor resection tends to be associated with a poor prognosis, resulting in death within a few months. An early and appropriate diagnosis may contribute to improvement in patient prognosis; however, it is extremely difficult to diagnose primary mucinous carcinoma of the thyroid. We present the seventh reported case of primary mucinous carcinoma in the thyroid gland; moreover, rhabdoid cells were detected, which, to our knowledge, is a novel finding. An 81-year-old Japanese woman was initially diagnosed with a poorly differentiated thyroid carcinoma, and she underwent a hemithyroidectomy. Pathological examination revealed the presence of abundant mucus and agglomeration of large atypical cells. Rhabdoid cells were also seen scattered among the tumor cells. Immunostaining was performed for various markers, and on the basis of these results, we diagnosed the lesion as primary mucinous carcinoma with rhabdoid cells in the thyroid gland. Ten months after surgery, recurrence was noted in the paratracheal lymph nodes; therefore, total resection of the residual thyroid gland and paratracheal lymphadenectomy with thyroid-stimulating hormone suppression were performed. The patient is currently alive and disease-free. The current case is of interest not only because of the rare histological findings, but also because the patient achieved long-term survival following diagnosis of a mucinous carcinoma. We believe this report will be helpful for diagnosing future cases of mucinous carcinoma of the thyroid.

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

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

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

    To report an unusual occurrence of recurrent hyperparathyroidism due to papillary thyroid carcinoma. We describe the clinical history, physical examination findings, laboratory values, imaging findings, and pathologic findings of a woman who developed recurrent hyperparathyroidism 13 years after successful parathyroidectomy. A 59-year-old woman presented to our clinic with recurrent primary hyperparathyroidism. In 1994, she presented with nephrolithiasis and underwent resection of a right superior parathyroid adenoma that resulted in clinical and biochemical cure. Her clinical course had been followed at periodic intervals, and she had been symptom-free and normocalcemic. In 2007, she again developed nephrolithiasis and was documented to have recurrent hyperparathyroidism. Imaging studies suggested a parathyroid adenoma near the right inferior pole of the thyroid. The patient had reoperative neck exploration. No obvious parathyroid adenoma was found and a right thyroid lobectomy was performed, which resulted in normalization of intraoperative intact parathyroid hormone levels, and the incision was closed. Final pathology demonstrated no parathyroid adenoma, but instead, a 1-cm papillary thyroid carcinoma that stained positive for parathyroid hormone. More than 6 months after surgery, she remains clinically and biochemically cured. Recurrent hyperparathyroidism occurs secondary to multiple causes. This case demonstrates the challenge a surgeon faces in managing recurrent disease and highlights a rare phenomenon of papillary thyroid cancer causing recurrent hyperparathyroidism.

    The thyroid gland is a rare site of clinically detectable tumor metastasis. As thyroid tumors are usually assumed to be primary in origin, its recognition as a secondary is difficult. We report a case of an 80-year old female who was referred to the Department of Surgery for a symptomatic thyroid nodule. Her medical history included a radical nephrectomy for renal cell carcinoma (RCC) nine years ago. During follow-up a pancreatic nodule was noted suggestive of a neuroendocrine tumor and the von Hippel-Lindau syndrome had to be ruled out. The fine-needle aspiration biopsy (FNAB) guided by ultrasound (US) of the thyroid nodule was inconclusive and a hemithyroidectomy and isthmectomy were performed. Histological examination revealed metastasis of a clear cell carcinoma. RCC disseminates in an unpredictable manner and can show late recurrences. Although secondary involvement of the thyroid gland by RCC is rare, it is still one of the more common neoplasms to metastasize to this site. There are no specific clinical features and few characteristic findings of metastatic thyroid carcinoma on imaging studies. FNAB is a useful procedure to diagnose metastatic thyroid cancer, but one should remain suspicious when the result for malignant cells is negative or indeterminate. After thyroidectomy the diagnosis of RCC is confirmed immunohistochemically. There is a clear survival benefit if a surgical approach to the thyroid metastasis is chosen. Thyroid metastasis should be considered in patients with a thyroid nodule and positive history for RCC. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full text of publication follows. Aim: the aims of this study are first to determine the prevalence of thyroid tissue along the thyroglossal tract on SPECT/CT and secondly to assess the contribution of this tissue to total neck I-131 activity in patients treated with I-131 ablation therapy after total thyroidectomy for thyroid cancer. Materials and methods: a total of 63 consecutive patients with well differentiated thyroid cancer treated with total thyroidectomy underwent whole body planar imaging and SPECT/CT of the neck 48 hours following ablative I-131 therapy. On SPECT/CT, thyroglossal tract thyroid tissue was defined as radioiodine activity in the anterior neck, superior to the thyroid bed in close proximity to the midline without evidence of localisation to lymph nodes. On planar imaging, thyroglossal tract thyroid tissue was defined as linear radioiodine activity in the midline of the neck superior to the thyroid bed. SPECT/CT and planar images were classified by two independent reviewers as positive, negative or equivocal with interobserver agreement quantified using a Kappa score. Disagreement was resolved using a third reviewer. Quantitation of thyroglossal tract thyroid tissue and total neck I-131 activity was performed using region of interest analysis on planar imaging following localisation on SPECT/CT. Results: thyroglossal tract thyroid tissue was present in 31/63 (49%; 95% CI: 37-61%) patients on SPECT/CT. In these 31 patients, thyroglossal tract thyroid tissue contributed to an average of 49% of total neck activity. Interobserver agreement was substantial on SPECT/CT (Kappa = 0.76; 95% CI: 0.61-0.91) and fair on planar imaging (Kappa = 0.31; 95% CI: 0.15-0.47). Conclusion: thyroid tissue along the thyroglossal tract was present in one half of patients in our study population and can contribute to a significant amount of total neck I-131 activity. Given the high prevalence of thyroglossal tract thyroid tissue, our results suggest that total neck

    Recent developments in oncogeriatric surgery focus on several items - preoperative risk estimation and identification of frail patients and optimalization of perioperative care. New screening tools are being evaluated and show promising results. There is increasing evidence that preoperative training of frail patients might decrease the rate of postoperative complications and increase survival. The recent trend towards individualized treatment schemes will certainly be of benefit for the elderly population. More tools are becoming available to answer the most difficult question of all, namely whether surgery is the optimal treatment in this individual frail elderly oncogeriatric patient.

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

    Beside varicose vein surgery, endovenous procedures (endovenous laser therapy, VNUS and foam sclerotherapy) are now therapeutic options with the following advantages: low invasiveness, only out-patient operations, quick resumption of general activities. Whether or not classical vein surgery today still fulfills patient demands was analysed by a study group of German vascular surgeons (ANG) as a multicentre patient questioning. The questionnaire was subdivided into eight main complexes with 24 questions about the early results of stripping operations (from start of preparation until suture removal) and the patients answers were analysed. Answers with points (1-6) and free answers were possible. Between 1.1.2005 and 31.3.2005 18 centres for vascular surgery collected 1708 questionnaires from patients after stripping operations. The complex "preparation and information about the operation" was scored with 1.33 to 1.39. The "general organisation" of the vascular centre was scored between 1.22 and 1.30. "Pain after operation" was rated at 1.98 (immediately), 2.26 (first day) and 2.12 (third day after operation). Reasons for other problems after surgery were haematoma (3.09), problems with the compression dressing (1.67), circulatory collapse (1.51), headache (1.33), nausea (1.25). The total score for all centres was 1.47. The early results after varicose vein surgery are good up to very good. The patients' reconvalescence time is short and there is a quick resumption of general activities. The invasiveness of vein surgery seems to be overestimated. Comparative studies to evaluate the new methods are necessary. Benchmarking projects like this study are essential parts of current quality control systems.

    Objective To assess the impact of respiratory tract infection in the postoperative period of cardiac surgery in relation to mortality and to identify patients at higher risk of developing this complication. Methods Cross-sectional observational study conducted at the Recovery of Cardiothoracic Surgery, using information from a database consisting of a total of 900 patients operated on in this hospital during the period from 01/07/2008 to 1/07/2009. We included patients whose medical records contained all the information required and undergoing elective surgery, totaling 109 patients with two excluded. Patients were divided into two groups, WITH and WITHOUT respiratory tract infection, as the development or respiratory tract infection in hospital, with patients in the group without respiratory tract infection, the result of randomization, using for the pairing of the groups the type of surgery performed. The outcome variables assessed were mortality, length of hospital stay and length of stay in intensive care unit. The means of quantitative variables were compared using the Wilcoxon and student t-test. Results The groups were similar (average age P=0.17; sex P=0.94; surgery performed P=0.85-1.00) Mortality in the WITH respiratory tract infection group was significantly higher (P<0.0001). The times of hospitalization and intensive care unit were significantly higher in respiratory tract infection (P<0.0001). The presence of respiratory tract infection was associated with the development of other complications such as renal failure dialysis and stroke P<0.00001 and P=0.002 respectively. Conclusion The development of respiratory tract infection postoperative cardiac surgery is related to higher mortality, longer periods of hospitalization and intensive care unit stay. PMID:26313727

    For many reasons, laparoscopic surgery has been performed worldwide. Due to logistical constraints its first steps occurred in Lubumbashi only in 2008. The aim of this presentation was to report authors’ ten-month experience of laparoscopic surgery at Lubumbashi Don Bosco Missionary Hospital (LDBMH): problems encountered and preliminary results. The study was a transsectional descriptive work with a convenient sampling. It only took in account patients with abdominal surgical condition who consented to undergo laparoscopic surgery and when logistical constraints of the procedure were found. Independent variables were patients’ demographic parameters, staff, equipments and consumable. Dependent parameters included surgical abdominal diseases, intra-operative circumstances and postoperative short term mortality and morbidity. Between 1stApril 2009 and 28th February 2010, 75 patients underwent laparoscopic surgery at the LDBMH making 1.5% of all abdominal surgical activities performed at this institution. The most performed procedure was appendicectomy for acute appendicitis (64%) followed by exploratory laparoscopy for various abdominal chronic pain (9.3%), adhesiolysis for repeated periods of subacute intestinal obstruction in previously laparotomised patients (9.3%), laparoscopic cholecystectomy for post acute cholecystitis on gall stone (5.3%) and partial colectomy for symptomatic redundant sigmoid colon (2.7%). There were 4% of conversion to laparotomy. Laparoscopic surgery consumed more time than laparotomy, mostly when dealing with appendicitis. However, postoperatively, patients did quite well. There was no death in this series. Nursing care was minimal with early discharge. These results are encouraging to pursue laparoscopic surgery with DRC Government and NGO's supports. PMID:26448805

    Full Text Available Purpose: Neoplasms of the thyroid gland are classified according to the cells they originate from and commonly develop from cells of follicular origin. The most common differentiated thyroid cancers (DTC are papillary and follicular carcinomas. Coexistence of two different histological types of primary follicular thyroid neoplasm is a rare condition. There are previous reports of concomitant medullary and papillary thyroid cancers. However, there is scarce data about the simultaneous occurrence of the two different histological types of primary follicular thyroid tumors and this is the first study on that subject. Material and Method: From January 2007 to September 2014, our institutional database was reviewed for patients who underwent thyroid surgery for various indications. Medical records and cytopathology reports of those patients were examined retrospectively. Simultaneous neoplasms of follicular origin were noted. Results: A total of 3.700 patients were operated. Histopathological examination revealed a benign pattern in 2.686 (73% patients and a malignant pattern in 1.014 (27% patients. Among the patients with the diagnosis of DTC, only 20 (1.9% had a concomitant neoplasm within the same thyroid gland. Discussion: Such simultaneous tumors may be a part of a familial tumor syndrome or an unidentified novel gene mutation playing role in the pathogenesis of more than one type of tumor. Based on the current evidence, the synchronous occurrence of those neoplasms in a given patient is likely coincidental in the literature. Further studies on larger patient population with standardized genetic characterization are needed.

    Full Text Available Objective: The incidence of thyroid cancer, the most common endocrine malignancy, has increased dramatically in the last fifty years. This article will review the standard approach to thyroid cancer treatment as well as novel therapies under investigation. We will also address potential cost considerations in the management of thyroid cancer.Study Design: A comprehensive literature search was performed.Methods: Review article.Results: The high prevalence of thyroid cancer and the availability of novel therapies for patients with metastatic disease have potential economic implications that have not been well-studied. Because many patients likely have very low morbidity from their cancers, better tools to identify the lowest risk patients are needed in order to prevent overtreatment. Improved risk stratification should include recognizing patients who are unlikely to benefit from radioactive iodine therapy after initial surgery and identifying those with indolent and asymptomatic metastatic disease that are unlikely to benefit from novel therapies. In patients with advanced incurable disease, randomized-controlled studies to assess the efficacy of novel agents are needed to determine if the costs associated with new agents are warranted.Conclusions: Health care costs associated with the increased diagnosis of thyroid cancer remain unknown but are worthy of further research.

    The purpose of this study is to compare the rate of local complications resulting from radioiodine ablation of thyroid cancer in patients with a residual intact thyroid lobe to that in patients who had more extensive surgical treatment prior to radioiodine administration. We retrospectively studied 59 patients who had received 131I between 1979 and 1989. The patients were divided into two groups, depending on the extent of their previous surgical thyroid excision. Group 1 comprised 10 patients with a lobectomy or hemithyroidectomy before the ablative radioiodine dose, and Group 2 comprised 49 patients with more extensive thyroid excision (near-total or subtotal thyroidectomy) before the radioiodine treatment. Sixty percent of the 10 patients in Group 1 experienced some degree of neck pain or tenderness following radioiodine ablation of their residual thyroid. In one case, the local reaction was very severe and accompanied by the development of transient hyperthyroidism. There was only a 6% local complication rate in the patients who had undergone more extensive thyroid excision before ablative therapy (p less than 0.001), and none had a severe reaction. Patients with only unilateral surgical excision before radioiodine therapy have a higher rate of local complications than do patients treated with more extensive surgery prior to radioiodine ablation. If radioiodine is to be employed in such patients, they should be informed of this possible complication. Since evidence supports a dose effect in the pathogenesis of the complications, we recommend using a dose of less than 30 mCi for the initial ablation in these patients even though it may be necessary to repeat this dose to complete thyroid ablation.

    Objective: RET / PTC gene rearrangement can lead to aberrant activation of tyrosine kinase receptors, which is a common mutation in papillary thyroid carcinoma (PTC). This study focuses on the association of RET / PTC rearrangements with PTC clinical factors. Methods: From January 2011 to December 2013, a total of 114 patients with PTC were enrolled in this study. Clinicopathological parameters, lifestyle, and thyroid hormone levels were collected. RET / PTC rearrangements were detected by TaqMan PCR and verified by Sanger sequencing.Data were analyzed with SPSS software, including chi-square test, Fisher ' s exact test, Mann - Whitney U test, Student ' s t -test, and Logistic regression. Results: RET / PTC rearrangements were not found in all paracancerous normal thyroid tissues, and were detected in 23.68% (27/114) of PTC. Further analysis revealed no correlation between RET / PTC rearrangement and thyroid function, clinicopathologic parameters, and lifestyle in the total PTC group or in the subgroup of patients with concomitant diseases (including Hashimoto's thyroiditis and nodular goiter). But in the subgroup of PTC without concomitant disease, RET / PTC rearrangement was associated with tumor multifocal ( P =0.018), and RET / PTC -positive PTC patients had an increased risk of tumor multifocal ( OR =5.57, 95% CI 1.39-22.33). It was also found that RET / PTC rearrangement was associated with an abnormal increase in TSH level of one month after surgery ( P = 0.037). Conclusion: Nodular goiter and Hashimoto 's thyroiditis may be a confounding factor in PTC. RET / PTC rearrangement may play an important role in the occurrence of thyroid carcinoma multifocal after exclusion of this confounding factor.

    The results of the investigations of radioactive contamination after the Chernobyl catastrophe and subsequent iodine prophylaxis on the thyroid gland function and morphology in Northeast Poland. The aim of the study was to determine whether potassium iodide in one dose during radioactive contamination in Poland limited the radioactive dose in the thyroid gland and if significant disadvantageous side-effects in the intra thyroid and extra thyroid occurred. Additionally during the studies we tried to determine if radioactive iodine contamination which occurred in the region of the Medical Academy in Bialystok caused an increase in thyroid disease. It is interesting to note the different results obtained after radioactive contamination with the results from the investigations in this same territory in 1983-1985. In 1983-1985, before the Chernobyl catastrophe, 6921 persons in Northeast Poland were investigated. In 1986-1988, immediately after the disaster 4010 persons were investigated. Changes in the thyroid were noticed by 187 persons (2.3% -11.7%) most of which were enlargement of the thyroid, but only a few were confirmed by a physician. In conclusion we confirmed a common feature of iodine prophylaxis, especially in children. Iodine prophylaxis was mostly used in April 1986, which was the best time for the predicted blocking effects. Iodine tolerance was good, the least number of side effects were observed after Lugol solution (one dose). The investigated pregnant women did not observe any complications in their children or deliveries. The epidemiological study confirmed a low degree of thyroid endemic in the investigated region with parenchymatous having a tendency to decrease and nodular goitre to increase. Our investigation would suggest that follow-up studies are necessary especially in the group with nodular goitre and those with persistent antithyroid antibodies. (author). 16 refs, 3 figs, 24 tabs

    We used infrared spectroscopy methods to study thyroid tumor tissues removed during surgery. The IR spectra of the surgical material are compared with data from histological examination. We show that in malignant neoplasms, the spectra of proteins in the region of C=O vibrations are different from the spectra of these substances in benign tumors and in tissues outside the pathological focus at a distance >1 cm from the margin of the tumor. The differences in the spectra are due to changes in the supermolecular structure of the proteins, resulting from rearrangement of the system of hydrogen bonds. We identify the spectral signs of malignant pathologies.

    Ultrasound is the most commonly used imaging technique for the evaluation of thyroid nodules. Sonographic findings are often not specific, and definitive diagnosis is usually made through fine-needle aspiration biopsy or even surgery. In reviewing the literature, terms used to describe nodules are often poorly defined and inconsistently applied. Several authors have recently described a standardized risk stratification system called the Thyroid Imaging, Reporting and Data System (TIRADS), modeled on the BI-RADS system for breast imaging. However, most of these TIRADS classifications have come from individual institutions, and none has been widely adopted in the United States. Under the auspices of the ACR, a committee was organized to develop TIRADS. The eventual goal is to provide practitioners with evidence-based recommendations for the management of thyroid nodules on the basis of a set of well-defined sonographic features or terms that can be applied to every lesion. Terms were chosen on the basis of demonstration of consistency with regard to performance in the diagnosis of thyroid cancer or, conversely, classifying a nodule as benign and avoiding follow-up. The initial portion of this project was aimed at standardizing the diagnostic approach to thyroid nodules with regard to terminology through the development of a lexicon. This white paper describes the consensus process and the resultant lexicon. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    Background Collaborations for global surgery face many challenges to achieve fair and safe patient care and to build sustainable capacity. The 2004 terrorist attack on a school in Beslan in North Ossetia in the Russian North Caucasus left many victims with complex otologic barotrauma. In response, we implemented a global surgery partnership between the Vladikavkaz Children's Hospital, international surgical teams, the North Ossetian Health Ministry, and civil society organizations. This study's aim was to describe the implementation and 5-year results of capacity building for complex surgery in a postconflict, mid-income setting. Design We conducted an observational study at the Children's Hospital in Vladikavkaz in the autonomous Republic of North Ossetia-Alania, part of the Russian Federation. We assessed the outcomes of 15 initial patients who received otologic surgeries for complex barotrauma resulting from the Beslan terrorism attack and for other indications, and report the incidence of intra- and postoperative complications. Results Patients were treated for trauma related to terrorism (53%) and for indications not related to violence (47%). None of the patients developed peri- or postoperative complications. Three patients (two victims of terrorism) who underwent repair of tympanic perforations presented with re-perforations. Four junior and senior surgeons were trained on-site and in Germany to perform and teach similar procedures autonomously. Conclusions In mid-income, postconflict settings, complex surgery can be safely implemented and achieve patient outcomes comparable to global standards. Capacity building can build on existing resources, such as operation room management, nursing, and anesthesia services.

    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

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

    Conclusions: Ranolazine may prove beneficial in POAF prevention following cardiac surgeries. Although the pooled treatment effect is quite impressive with a reduction of more than 50% of risk of developing POAF, small number of studies and variation in ranolazine dose regimen in each study make our results inconclusive, but worthy of further investigation. That is why this result has to be interpreted as only hypothesis generating, rather than conclusion drawing.

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

    Seventeen cases (5 males and 12 females) of anaplastic carcinoma of the thyroid gland treated at the Department of Otolaryngology-Head and Neck Surgery, Kurume University School of Medicine, between January 1999 and January 2009 were reviewed. Ages of the patients ranged from 54 to 94 years. Six cases were treated by radical surgery. All cases were treated by radiotherapy and 5 cases received additional chemotherapy. The 6 cases treated by radical surgery were able to experience home life. Survival time of the radical surgery cases ranged from 8 to 36 months, with a median of 17 months. In cases without surgery, the survival time ranged from 1 to 8 months, with a median of 4 months. As the final outcome, only 1 case is alive after 36 months; 8 cases died by primary tumor, 7 by lung metastasis and 1 by suicide. Although the prognosis of anaplastic carcinoma of the thyroid gland is generally poor, radical surgery, if possible, may provide better survival results. (author)

    The optimal surgical management of locally advanced breast cancer (LABC) remains undefined. The aim of the study was to obtain long-term results of oncoplastic surgery in terms of overall survival, loco-regional recurrence, and quality of life in case of LABC. Prospective cohort study enrolled 60 patients with stage III breast cancer. Forty-two (70%) patients received neo-adjuvant chemotherapy, 28 patients were considered suitable for surgery as initial treatment option. Type II oncoplastic surgery was performed for all patients: hemimastectomy and breast reconstruction with latissimus dorsi flap - for 29 (48.3%), lumpectomy - 31 (51.7%), and reconstruction with subaxillary flap for four (6.7%), with bilateral reduction mammoplasty - 14 (23.3%) and with J-plastic - 13 (21.7%) patients. Adjuvant chemotherapy and hormonal therapy followed surgery for all, except one, patients. Sequential radiotherapy was administered for all patients. The mean period of follow-up was 86 months. Postoperative morbidity rate was 5%. Local-regional recurrence was detected in six (10%) patients. After reoperation no local relapse was diagnosed. However, three of these patients had systemic dissemination of the disease. Distant metastasis was detected in 23 (38.3%) patients. Distant metastasis-free survival at 5 years was 61.7%. Fourteen patients died (23.3%). A total of 87.2% of the patients had good and excellent esthetic outcome. Oncoplastic breast-conserving surgery can be proposed for selected patients with LABC with acceptable complication, local recurrence rate, and good esthetic results. © 2013 Wiley Periodicals, Inc.

The purpose of this study was to investigate the prevalence of sarcopenia and evaluated its impact on the results of lumbar spinal surgery. Methods: This study included 2 groups: One group consisted of patients who underwent whole-body dual-energy X-ray absorptiometry (DXA scanning before the option of undergoing surgery for lumbar spinal disease (LSD group and a second group consisted of patients underwent DXA scanning for osteoporosis screening under hospital watch at the geriatric medicine department (control group. In order to evaluate the impact of sarcopenia on the clinical outcome of lumbar spinal surgery, the Japanese Orthopedic Association (JOA score, the recovery rate based on the JOA score, and visual analogue scale (VAS scores for lower back pain, lower extremity pain, and lower extremity numbness were compared within the LSD group. Results: The prevalence of sarcopenia showed no statistical difference between groups (control group, 50.7%; LSD group, 46.5%. In the LSD group, while the changes in VAS scores showed no statistical difference between the nonsarcopenia subgroup and sarcopenia subgroup, the sarcopenia subgroup demonstrated inferior JOA scores and recovery rates at the final follow-up when compared with the nonsarcopenia subgroup (P < 0.05. Conclusions: This study demonstrated a high prevalence of sarcopenia among the elderly populations in Japan and a negative impact of sarcopenia on clinical outcomes after lumbar spinal surgery.

    Full Text Available ABSTRACT Objective: to analyze possible negative effects of Attention Deficit Hyperactivity Disorder (ADHD on the success of bariatric surgery. Methods: we evaluated forty patients undergoing bariatric surgery and with regular post-operative follow-up of at least one year. To all, we applied the questionnaire advocated in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV of the American Psychiatric Association for ADHD, as well as analyzed their postoperative data. Results: fifteen (38% patients presented a positive questionnaire for ADHD. Patients with ADHD presented higher BMI than patients without the disorder (45.8 vs. 40.9 kg/m2, p=0.017, and the difference remained in all postoperative stages. There was no statistically significant difference in surgery success (33.3% x 66.7%, p=0.505 or in BMI reduction (30.71% x 31.88%, p=0.671 one year after the procedure. Conclusion: ADHD patients have a higher BMI. However, the presence of ADHD does not influence the success of bariatric surgery and the reduction of BMI.

    While thyroidectomy is considered a safe surgery, dedicated tools facilitating tissue identification during surgery could improve its outcome. The most common complication following surgery is hypocalcaemia, which results from iatrogenic removal or damage to parathyroid glands. This research project aims at developing and validating an instrument based on optical microscopy modalities to identify tissues in real time during surgery. Our approach is based on a combination of reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) to obtain multi-scale morphological contrast images. The orthogonal field of views provide information to navigate through the sample. To allow simultaneous, synchronized video-rate imaging in both modalities, we designed and built a dual-band wavelength-swept laser which scans a 30 nm band centered at 780 nm and a 90 nm band centered at 1310 nm. We built an imaging setup integrating a custom-made objective lens and a double-clad fibre coupler optimized for confocal microscopy. It features high resolutions in RCM (2µm lateral and 20 µm axial) in a 500 µm x 500 µm field-of-view and a larger field-of-view of 2 mm (lateral) x 5 mm (axial) with 20 µm lateral and axial resolutions in OCT. Imaging of ex vivo animal samples is demonstrated on a bench-top system. Tissues that are visually difficult to distinguish from each other intra-operatively such as parathyroid gland, lymph nodes and adipose tissue are imaged to show the potential of this approach in differentiating neck tissues. We will also provide an update on our ongoing clinical pilot study on patients undergoing thyroidectomy.

    Full Text Available 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.

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

    The technique of functional endoscopic sinus surgery (FESS) has been widely accepted and applied to inflammatory diseases of the paranasal sinuses with internationally reported results of this technique having been very good. Our objective was to find out outcome after FESS at our centre. Two hundred patients who had undergone FESS during a two year period with an average follow-up period of eleven months were evaluated subjectively regarding the outcome of their endoscopic sinus surgery. An overall subjective improvement of about 94% was documented, with improvement in specific symptoms such as headache, nasal congestion, change in sense of smell, nasal discharge and recurrent infections ranging from 52% to 97%. Our center reports a subjective improvement of symptoms following FESS compatible with results attained internationally. (author)

    During 3,5 years (July 74 - December 77) 130 cases of subacute thyroiditis were observed at Londrina county, North area of Parana State; this disease was considered a peculiar problem of local pathology on thyroid disorders. These cases had the following distribution: 89 in the initial stage, 36 in the transition, 2 in remission and another 3 considered as of delayed and ciclic character. Women predominated by a factor of 5,19; the peak age was 30-40 years and it had a seasonal preference for winter and spring. Factors that mislead the diagnosis are pre-existing goiter (12,3%) and infectious diseases of the upper respiratory tract (35,38%). The goiter was diffuse in 50% of the cases and nodular in 30%; the thyroid had a normal size in the others. Painless gland occurred in 5 cases. The laboratory examinations are so important for diagnosis as for disease staging and evolution. Thyrotoxicosis occurred in 31 cases of the initial stage. Hypothyroidism in the transition state was present in 8 cases: 1 clinical and 7 subclinical. Evidence, for permanent functional impairment was demonstrated for 2 patients. Corticotherapy was the effective treatment, without evidence of good response with analgesic-antiinflammatory association. Thyrotoxicosis of the initial stage showed satisfactory results to the propanalol (β adrenergic blockage). Surgery was restricted to patients with eventual residual nodule. (author) [pt

    Anaplastic thyroid cancer (ATC) is rare and a highly fatal malignancy. The role of programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) as prognostic and/or predictive markers in ATC is unknown. Multimodal therapy offers the best chance at tumor control. The objective of this study was to detect potential associations of PD-1/PD-L1 axis variables with outcome data in ATC. Retrospective study of a uniformly treated cohort. Single institution retrospective cohort study. Sixteen patients who received intensity-modulated radiation therapy (15 had preceding surgery) were studied. Patients treated with multimodal therapy were followed and assessed for overall survival (OS) and progression-free survival (PFS). All samples demonstrated PD-1 expression in inflammatory cells whereas tumor cells were primarily negative. PD-L1 was expressed on ATC tumor cells in most samples and showed mainly membranous staining. High PD-1 expression (>40% staining) in inflammatory cells was associated with worse overall survival (OS; hazard ratio, 3.36; 95% confidence interval, 1.00 to 12.96; P 33% staining) trended toward worse PFS and OS. PD-1/PD-L1 pathway proteins are highly expressed in ATC tumor samples and appear to represent predictive markers of PFS and OS in multimodality-treated ATC patients.

    The purpose of this study was to categorize macrocalcifications into several subtypes by the US findings and to determine which type of macrocalcification in a thyroid nodule is associated with thyroid malignancy. We retrospectively analyzed the macrocalcification patterns of thyroid nodules in 396 patients that underwent ultrasonography (US)-guided thyroid FNA or surgery in our institution between August 2009 and August 2011. Two radiologists evaluated US findings and categorized macrocalcifications into 5 subtyes : (A) solitary macrocalcification no association with thyroid nodule; (B) nodular macrocalcification( s) within indeterminate thyroid nodule; (C) dense macrocalcification without ability to interpret internal content by its posterior acoustic shadowing; (D) irregular- shaped macrocalcification(s); (E) macrocalcification with other suspicious malignant US finding(s). A chi-squared test and a Fisher exact test were used for comparison of categoric variables. The diagnostic sensitivity, specificity, positive and negative predictive values (PPV and NPV) were obtained. Among total of 417 nodules, 114 (27.3%) were suspicious malignancy or malignancy on histopathological result. Macrocalcification with other malignant US feature had the highest incidence of malignancy (77.5%), followed by irregular-shaped macrocalcification(s) (43.9%), and dense macrocalcification without ability to interpret internal content by its posterior acoustic shadowing (38.5%), solitary macrocalcification no association with thyroid nodule (8.3%) respectively, and nodular macrocalcification( s) with indeterminate thyroid nodule had the lowest incidence (7.5%). A nodule with macrocalcification with other malignant US finding(s) has the highest odds ratio (42.52), followed by a nodule with irregular-shaped macrocalcification(s) (9.65) and dense macrocalcification (7.72). Leaving macrocalcification with compositive malignant findings aside, irregular-shaped macrocalcification is more

    To evaluate the characteristic ultrasonographic (US) features of metastatic carcinoma to the thyroid, and how accurate US features and ultrasonography-guided fine-needle aspiration (US-FNA) are for the diagnosis of thyroid metastases. Twenty-three thyroid lesions in 23 patients (mean age, 66.7 years; range, 46 to 85 years) that had been diagnosed as thyroid metastases were included. The composition, echogenicity, margin, shape, presence of calcifications, underlying parenchymal echotexture, and vascularity were analyzed in US images of the thyroid metastases. Final US assessments were categorized into probably benign and suspicious malignancy. The presence of suspicious metastatic cervical lymph nodes was noted. The medical records, US-FNA cytology, and pathology reports of these patients were retrospectively reviewed. Of the 23 thyroid lesions, the general US appearance was mass-forming in 21 (91.3%) and non-mass-forming in 2 (8.7%). All 23 lesions showed a solid tumor composition. Common US features among the 21 mass-forming thyroid metastases were hypoechogenicity (81.0%), non-circumscribed margins (90.5%), no calcifications (76.2%), and parallel shape (81.0%). Suspicious cervical lymph nodes were present in 18 patients (78.3%). Of the 23 lesions, 21 (91.3%) were classified as suspicious malignancy, and 2 (8.7%) as probably benign. US-FNA showed diagnostic results specific for metastases in 21 of the 22 patients (95.5%) who had undergone US-FNA. Common US features in thyroid metastasis were hypoechogenicity, non-circumscribed margins, no calcifications, parallel shape, and the presence of suspicious cervical lymph nodes. US-FNA can be effectively used in the diagnosis of thyroid metastasis, preventing unnecessary surgery.

  19. Thyroid gland development and defects.

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

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

    Spinal cord stimulation is a widely-accepted technique in the treatment of back pain resulting from failed back surgery. Classically, stimulation has been carried out with percutaneous electrodes implanted under local anaesthesia and sedation. However, the ease of migration and the difficulty of reproducing electrical paresthesias in large areas with such electrodes has led to increasing use of surgical plate leads, which have the disadvantage of the need for general anaesthesia and a laminectomy for implantation. Our objective was to report the clinical results, technical details, advantages and benefits of laminectomy lead placement under epidural anaesthesia in failed back surgery syndrome cases. Spinal cord stimulation was performed in a total of 119 patients (52 men and 67 women), aged between 31 and 73 years (average, 47.3). Epidural anaesthesia was induced with ropivacaine. In all cases we inserted the octapolar or 16-polar lead in the epidural space through a small laminectomy. The final position of the leads was the vertebral level that provided coverage of the patient's pain. The electrodes were connected at dual-channel or rechargeable pulse generators. After a mean follow-up of 4.7 years, the results in terms of improvement of the previous painful situation was satisfactory, with an analgesia level of 58% of axial pain and 60% of radicular pain in more than 70% of cases. None of the patients said that the surgery stage was painful or unpleasant. No serious complications were included in the group, but in 6 cases the system had to be explanted because of ineffectiveness or intolerance of long-term neurostimulation. This study, with a significant number of patients, used epidural anaesthesia for spinal cord stimulation of lead implants by laminectomy in failed back surgery syndromes. The technique seems to be safe and effective. Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España. All rights reserved.

    To assess the anatomical and visual outcome and also the retinal complications following vitreoretinal surgery for posterior segment intraocular foreign bodies (IOFBs). Retrospective analysis of 59 IOFBs, with different locations within posterior segment,removed during pars plana vitrectomy (PPV) between January 1999 and January 2011, by the same surgeon, in Eye Clinic 1 Iasi. 47 out of 59 IOFBs (79.66%) were removed immediately after primary wound closure and 12 with a delay ranging from 48 hours to 5 years. All IOFBs were metallic. Total 20G pars plana vitrectomy with IOFB removal by forceps or intraocular magnet, careful membrane peeling and laser photocoagulation around the retinal injury (if present) was performed. Relaxing retinotomy was necessary in 3 cases of retinal incarceration. Endotamponade with SF6 (26 cases) or silicone oil (8 cases) were performed, if needed, at the end of surgery. The average follow-up period after surgery was 17.9 month (ranging 6 - 36 months). 18 out of 59 IOFBs (30.5%) were intraretinal. 39 out of 59 eyes (66.10%) showed signs of endophthalmitis at the time of surgery. Preoperative visual acuity ranged from light perception to 0.6. The mean visual acuity significantly increased after surgery from 0.16 preoperatively to 0.5 at the end of follow-up (range hand movements--1). 51 out of 59 cases (86.44%) had stable anatomical result. A final visual acuity equal or better than 0.1 was obtained in 45 cases (76.27%). Mild retinal folding could be noticed in some cases around the laser-treated retinal injury. In 8 out of 59 cases (13.56%) visual acuity remained low or decreased due to macular injury or PVR associated retinal detachment requiring additional surgery. IOFBs, and especially those intraretinal, require an early, complex and customized approach during PPV. Functional results do not match anatomical restoration if macula or optic nerve are impacted. Main postoperative complications were represented by retinal folds and PVR

    Objectives: There is limited endosonographic literature regarding thyroid gland pathology, which is frequently visualized during upper endoscopic ultrasound (EUS). Our objective was to assess the prevalence of benign and malignant thyroid lesions encountered during routine upper EUS within a cancer center setting. Materials and Methods: The data were prospectively collected and retrospectively analyzed. All upper EUS procedures performed between October 2012 and July 2014 were reviewed at a large referral cancer center. Data collected included patient demographics, preexisting thyroid conditions, thyroid gland dimensions, the presence or absence of thyroid lesions, and EUS morphology of lesions if present, and interventions performed to characterize thyroid lesions and pathology results when applicable. Results: Two hundred and forty-five EUS procedures were reviewed. Of these, 100 cases reported a detailed endosonographic examination of the thyroid gland. Most of the thyroid glands were endosonographically visualized when the tip of the scope was at 18 cm from the incisors. Twelve cases showed thyroid lesions, out of which three previously undiagnosed thyroid cancers were visualized during EUS (two primary papillary thyroid cancers and one anaplastic thyroid cancer). Transesophageal EUS-guided fine needle aspiration of thyroid lesions was feasible when the lesion was in the inferior portion of the thyroid gland, and the tip of the scope was at 18 cm or more from the incisors. Conclusions: Routine EUS examination may detect unexpected thyroid lesions including malignant ones. We encourage endosonographers to screen the visualized portions of the thyroid gland during routine withdrawal of the echoendoscope. PMID:27803906

    Treatment results for uterine cervix cancer were evaluated using a new concept named ''Effective Survival Rate''. This rate was calculated by subtracting the weighted sum of incidence rates of various complications from the 5-year survival rate. The numerical values for various complications were assigned as follows: surgical death, 1.0; severe complications, such as fistula ureterovaginalis and ileus, 0.5; mild complications, such as rectum and urinary bladder complications, 0.3 and 0.2. These values were determined with reference to the Karnofsky index of performance status. The effective survival rate was calculated for patients with satage 2 and 3 uterine cervix cancer treated by radiation therapy and surgery, and compared as a function of age between 30 and 70 years. We concluded that the effective survival rate was comparable for radiation therapy and surgery for stage 2 uterine cervix cancer. However, in patients with stage 3, radiation therapy was superior.

    The Western Canada Waiting List Project (WCWL) is a federally funded partnership of 19 organizations, including medical associations, health authorities, ministries of health and research organizations, that was created to develop tools to assist in the management of waiting lists. The WCWL cataract surgery panel, one of five panels constituted under this project, developed and tested a set of standardized clinical criteria for prioritizing among patients awaiting cataract surgery. The cataract surgery panel was composed of seven academic and community ophthalmologists, two family physicians, an optometrist, a health care services researcher and a health information specialist. The panel met three times between October 1999 and June 2000. The priority criteria were applied to 563 patients in the four western provinces. Regression analysis was used to determine the set of criteria weights that collectively best predicted clinicians' overall ratings of urgency. Interrater and test-retest reliability were assessed, based on clinicians' ratings of videotaped interviews with six hypothetical patients. The resulting criteria accounted for about one-third of the observed variance in clinicians' ratings of overall clinical urgency (R2 = 31.2%). The panel modified the original criteria and weights based on empirical results and clinical judgement. Reliability of the revised criteria items was mixed, with the lowest reliability observed for items dealing with glare and social role. Participating clinicians considered the criteria easy to use and reasonably reflective of expert surgical judgement regarding clinical urgency. Further development and testing of the tool appear warranted.

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

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

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

    Evidence suggests that in most industrialized countries autoimmune disorders, including chronic lymphocytic thyroiditis, are increasing. This increase parallels the one regarding differentiated thyroid cancer, the increment of which is mainly due to the papillary histotype. A number of studies have pointed to an association between chronic lymphocytic thyroiditis and differentiated thyroid cancer. The upward trend of these two thyroid diseases is sustained by certain environmental factors, such as polluting substances acting as endocrine disrupting chemicals. Herein we will review the experimental and clinical literature that highlights the effects of environmental and occupational exposure to polluting chemicals in the development of autoimmune thyroid disease or differentiated thyroid cancer. Stakeholders, starting from policymarkers, should become more sensitive to the consequences for the thyroid resulting from exposure to EDC. Indeed, the economic burden resulting from such consequences has not been quantified thus far.

    Decreased scarring is an advantage of minimally invasive surgery. The new experimental technique of natural orifice transluminal surgery (NOTES) aims at totally scarless surgery. We examined the general attitudes of patients and unaffected persons towards scarless surgery. We used a 7-item questionnaire in structured interviews with hospital visitors, following detailed standardized explanation of terms used and of possible complications, to groups of 10 participants, during an "open ward" day. A visual analog scale (VAS) from 1 (none) to 10 (very much) was used for all but one item. Questions concerned the importance of cosmetic results in abdominal surgery, satisfaction regarding existing scars, hypothetical acceptance of increased risk as a trade-off for the absence of scars, and other issues. Data were analyzed for participants overall, and for three age groups and both sexes. 292 participants (male : female 1 : 1; mean age 43 years) completed the questionnaire. Cosmetic issues were rated as important (median 8), but acceptance of existing scars was also high in those affected (median 8, n=68). Approval of scarless surgery decreased with a presumed risk increase (from score 9 down to score 5), and overall an increase in risk of 10 % was judged to be acceptable as a trade-off for total absence of scarring. Younger people tended to be less satisfied with scars, but were also less inclined than older people to accept higher surgical risk in this hypothetical context. People generally seem to favor scarless abdominal surgery, even with some increase in risk.

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

    There is limited endosonographic literature regarding thyroid gland pathology, which is frequently visualized during upper endoscopic ultrasound (EUS). Our objective was to assess the prevalence of benign and malignant thyroid lesions encountered during routine upper EUS within a cancer center setting. The data were prospectively collected and retrospectively analyzed. All upper EUS procedures performed between October 2012 and July 2014 were reviewed at a large referral cancer center. Data collected included patient demographics, preexisting thyroid conditions, thyroid gland dimensions, the presence or absence of thyroid lesions, and EUS morphology of lesions if present, and interventions performed to characterize thyroid lesions and pathology results when applicable. Two hundred and forty-five EUS procedures were reviewed. Of these, 100 cases reported a detailed endosonographic examination of the thyroid gland. Most of the thyroid glands were endosonographically visualized when the tip of the scope was at 18 cm from the incisors. Twelve cases showed thyroid lesions, out of which three previously undiagnosed thyroid cancers were visualized during EUS (two primary papillary thyroid cancers and one anaplastic thyroid cancer). Transesophageal EUS-guided fine needle aspiration of thyroid lesions was feasible when the lesion was in the inferior portion of the thyroid gland, and the tip of the scope was at 18 cm or more from the incisors. Routine EUS examination may detect unexpected thyroid lesions including malignant ones. We encourage endosonographers to screen the visualized portions of the thyroid gland during routine withdrawal of the echoendoscope.

    To clarify the indications for deconstructive endovascular surgery in patients with large and giant intracranial aneurysms and to evaluate short-term and long-term postoperative outcomes. The study was based on a retrospective analysis of the treatment results in 50 patients with large (15-25 mm) and giant (more than 25 mm) intracranial aneurysms, aged from 18 to 75 years, who were treated at the Burdenko Neurosurgical Institute in 2002-2014. The patients underwent a balloon occlusion test (BOT) in various modifications before stationary occlusion of the carrier artery. For vascular occlusion, we used detachable latex balloon catheters (33 cases) and microcoils (17 cases). The condition of patients in the pre- and postoperative period was assessed by using the modified Rankin Scale. There were no deaths due to occlusion of the internal carotid artery (37 patients). Postoperative complications occurred in 5 patients. On the basis of BOT, revascularization surgery involving placement of an extra-intracranial microanastomosis (EICMA) was performed in 6 cases. In more 4 cases, EICMA was placed in the early postoperative period due to developing signs of ischemia. Two of 7 patients underwent occlusion of both vertebral arteries (VAs) in the vertebrobasilar basin, which led to fatal outcomes. One more patient died of aggravation of brainstem compression after VA occlusion. There was no worsening of neurological symptoms among survivors. There were no deaths and persistent neurological disorders upon occlusion of branches of the main cerebral arteries, starting with the first order arteries (6 patients). Thirty one patients (66%) were followed-up in the period from 1 to 104 months. There were no deaths associated with artery occlusion. Two patients experienced delayed ischemic disorders. Occlusion of the carrier artery should be performed in a carefully selected group of BOT-negative patients. This surgery can be indicated for aneurysms with a complicated configuration

    Neurologic development follows orderly patterns that can be severely disturbed when thyroid hormones are deficient or excessive. Should this occur at appropriate development periods, irreversible neurologic damage can result. The nature of the deficits depends upon the specific development period and the severity of the thyroid disturbance. PCBs and dioxins are structurally similar to the thyroid hormones. Their binding characteristics are similar to those of thyroid hormones and all three gr...

    Thyroid hypofunctional ('scintigraphic cool or cold') nodules are detected frequently. Dependent on the clinical situation, on morbidity and on economic aspects it is necessary to select patients for surgery and to avoid unnecessary surgical treatment. Therefore it is necessary to develop appropriate diagnostic algorithm to manage hypofunctional thyroid nodules. The ultrasound guided fine-needle aspiration cytology (FNA) is on the one hand side a useful diagnostic tool, but on the other hand side there exist certain limitations. It is questionable if the nodule is correctly reached. In case of heterogeneous larger mixed nodules or multiple hypofunctional nodules, it is difficult to choose the correct location of punctation. Furthermore a certain number of FNA's is not diagnostic without any result or due to 'follicular neoplasia'. {sup 99m}Tc-MIBI-sctintigraphy (MIBI) and {sup 18}F-FDG-positron-emission-tomography (FDG-PET) are established methods in the follow-up of differentiated thyroid cancer after thyroidectomy with elevated thyroglobulin-levels without adequate 131-Iodine-uptake. Moreover in case of parafollicular medullary thyroid carcinomas after thyroidectomy with elevated calcitonin-concentrations the FDG-PET is a valuable diagnostic method in localizing tumor. However these tracers gain in importance in differentiating malignant from benign preoperative hypofunctional nodules. In conclusion MIBI-scintigraphy should be used routinely to plan the correct guide of FNA. The application of both methods (MIBI and FNA) improves the differentiation of dignity, whereas a negative MIBI-examination and a negative FNA is able to exclude malignancy nearly. In this way the number of unnecessary numbers of surgical treatments can be reduced. FDG-PET is not definitely superior compared to MIBI-scintigraphy. From the cost perspective MIBI is more attractive than FDG-PET. (orig.)

    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.

    Intraoperative management of thyroid gland in laryngeal and hypopharyngeal cancer is controversial. The objectives of this study were to determine the incidence of thyroid gland invasion in patients undergoing surgery for laryngeal or hypopharyngeal carcinoma, to assess predictive factors and to assess the prognosis in patients with and without thyroid gland invasion. One hundred and thirty-three patients who underwent surgery for carcinoma larynx and hypopharynx from 2006 to 2010 were reviewed retrospectively. Surgical specimens were examined to determine the incidence of thyroid gland invasion and predictive factors were analysed. The recurrence rate and the survival in patients with and without thyroid gland invasion were also analysed. Out of the 133 patients with carcinoma larynx and hypopharynx who underwent surgery, histological thyroid gland invasion was observed in 28/133 (21%) patients. Significant relationship was found between histological thyroid gland invasion and preoperative evidence of thyroid cartilage erosion by CT scan and also when gross thyroid gland involvement observed during surgery. There is significant association between thyroid gland invasion when there is upper oesophageal or subglottic involvement. After analysing the retrospective data from our study, we would like to suggest that thyroid gland need not be removed routinely in all laryngectomies, unless there is advanced disease with thyroid cartilage erosion and gross thyroid gland involvement or disease with significant subglottic or oesophageal involvement.

    The use of a 15-watt diode laser (CeramOptec)in 30 surgical procedures in dogs and cats was reviewed. Ease of use, operator safety, hemostasis control, wound healing, surgical time, complication rate, and pain control were observed and recorded. Procedures performed were partial pancreatectomy, nasal carcinoma ablation, medial meniscus channeling, perianal and anorectal mass removal (5), hemangioma and hemangiopericytoma removal from two legs, benign skin mass removal (7), liver lobectomy, partial prostatectomy, soft palate resection, partial arytenoidectomy, partial ablation of a thyroid carcinoma, photo-vaporization of the tumor bed following malignant tumor resection (4), neurosheath tumor removal from the tongue, tail sebaceous cyst resection, malignant mammary tumor and mast cell tumor removal. The laser was found to be very simple and safe to use. Hemostasis was excellent in all but the liver and prostate surgeries. The laser was particularly effective in preventing hemorrhage during perianal, anal, and tongue mass removal. It is estimated that a time and blood loss savings of 50% over that of conventional surgery occurred with the use of the laser. All external wounds made by laser appeared to heal faster and with less inflammation than those made with a conventional or electrosurgical scalpel.

    The aim of this publication is to describe retrospectively the results of the surgical technique of AMS MiniArc for the treatment of female urinary incontinence, evaluate its results at 4 years follow-up. We present a retrospective cohort study of 135 patients, 110 (81.5%) had urinary incontinence and 25 (18.5%) mixed urinary incontinence. All these procedures were performed with local anesthesia and in "out patient surgery". Patients were monitored in the outpatient clinic at 6 months (control 1), one year (control 2) and annually (control 3, 4, and 5). During the following up, clinical history was made in every woman with ICIQ-SF questionnaire, that included a fourth question to evaluate the degree of satisfaction after surgery, as well as physical examination. We considered objective cure when negative stress with full bladder. We use the SPSS program (V19.0) for statistical analysis of the results. The mean follow-up was of 59 months (range from 33 to 72 months). When evaluating the success rate of anti-incontinence surgery, 86.7% of patients showed objective cured (80.8% with MUI and 89.2% with SUI). The ICIQ-SF decreased average of 12.7 points, 85.7% patients were very or fairly satisfied. The AMS MiniArc is an optim anti-incontinence procedure a medium term. But the results should be interpreted with caution given the limitations of the study. Copyright © 2013 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    It has been well documented that the thyroid gland is one of the most radiosensitive of organs, especially when exposure occurs during childhood. It is known as well that childhood exposure to radioactive iodine increases thyroid cancer risk. Conducting thyroid screening in regions adjacent to the Semipalatinsk Test Site (STS) area is very important for medical examination, data management and thyroid dose reconstruction. Our experience of thyroid screening based on our screening projects in Kurchatov and several regions adjacent to STS (more than 4,000 screened patients) allowed to work out the most appropriate screening protocol. A retrospective analysis of the results of surgical treatment of the 7,271 patients with thyroid abnormalities in the Semipalatinsk, Pavlodar and Ust-Kamenogorsk regions of Kazakstan and study the histological staging of 7,271 surgically removed thyroid glands was preceded by our thyroid screening projects. Ours is the first study in the Semipalatinsk region that covers the period 1966-1998.Taking into account the onset of population effective doses during 1962, it was decided to distinguish 6 periods of observation. It is known that basic effective equivalent doses for the majority of the region's population were established by radioactive events in the period 1949-1962. This explains our focus on the year 1962, but thyroid dose reconstruction matter as well as other radiation related problems are still in the progress. We need to get the accurate dosimetry data. Selection of study subjects based on the appropriate criteria needed to be adjusted and clarified in accordance with the main goal of the project and radiation related information. All specialists involved in the thyroid screening project, data management, data analyses and interpretation of the results must be trained and must be highly qualified specialists in this field of science and practice.

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

    Recommended treatment for most patients with differentiated thyroid cancer is surgery followed by radioiodine ablation. Current practice in many centres is to use a high administered activity of 3.7 GBq (100 mCi). However, a lower activity (1.1 GBq or 30 mCi) has advantages including a shorter stay in hospital isolation and lower risk of side effects, including the risk of a second cancer. Also, Thyrogen (rhTSH) allows patients to continue thyroid hormone replacement during ablation, avoiding symptoms of hypothyroidism and also reduces total body radiation dose. We conducted a large randomized factorial multi centre trial to simultaneously address whether ablation success rates are similar using (i) either 1.1 GBq or 3.7 GBq, and (ii) either Thyrogen or thyroid hormone withdrawal. It is the first ever national prospective trial in thyroid cancer in the UK. Final results will be available in 2011

    2008-01-01

    According to common scientific opinion thyroglobulin (hTg) is not recommended as a tumor marker for clarifying the dignity of thyroid nodules, due to a strong overlap between values of differentiated thyroid carcinoma (DTC) and benign thyroid nodules. Moreover, other benign thyroid diseases with cellular lesion, i.e. nodules and overt inflammation, lead to significantly increased thyroglobulin values (values in a four-digit range and even more in very rare cases). The determination of hTg before thyroid ablation can be a useful ''screening marker'' for patients with CUP-syndrome and suspicious thyroid lesions to identify subjects suffering under DTC. Furthermore, in the case of DTC preoperatively measured hTg will help to validate and evaluate hTg values in the follow-up of these patients. hTg determination can be disturbed by methodological artefacts, in particular by interfering anti-hTg auto-antibodies. For the authentication of hTg values anti-hTg auto-antibody measurement and/or recovery testing is therefore essential although both methods have advantages and disadvantages in that respect. Calcitonin (hCt) is a relatively reliable and specific marker for medullary thyroid carcinoma (MTC) or neoplastic C-cell hyperplasia provided that optimal techniques and appropriate interpretation of test results are applied. The use of two-site assays with a high specificity for the monomer molecule is advised, but false-positive values can still occur, i.e. in renal insufficiency, during therapy with proton pump inhibitors, in goiters with ''physiological'' C-cell hyperplasia and in autoimmune thyroiditis. The Thyroid Section of the German Society of Endocrinology recommends hCt-screening for patients with nodular goiter although some questions regarding epidemiology, health economy and methodology are not resolved yet. Basal hCT values exceeding 100 pg/ml are highly predictive for MTC after exclusion of the reasons mentioned above which can cause artificially increased

    Full Text Available The treatment of differentiated thyroid carcinoma (DTC is surgery followed in some cases by adjuvant treatment, mostly with radioactive iodine (RAI. External beam radiotherapy (EBRT is less common and not a well-established treatment modality in DTC. The risk of recurrence depends on three major prognostic factors: extra-thyroid extension, patient’s age, and tumor with reduced iodine uptake. Increased risk for recurrence is a major factor in the decision whether to treat the patient with EBRT. Data about the use of EBRT in DTC are limited to small retrospective studies. Most series have demonstrated an increase in loco-regional control. The risk/benefit from giving EBRT requires careful patient selection. Different scoring systems have been proposed by different investigators and centers. The authors encourage clinicians treating DTC to become familiarized with those scoring systems and to use them in the management of different cases. The irradiated volume should include areas of risk for microscopic disease. Determining those areas in each case can be difficult and requires detailed knowledge of the surgery and pathological results, and also understanding of the disease-spreading pattern. Treatment with EBRT in DTC can be beneficial, and data support the use of EBRT in high-risk patients. Randomized controlled trials are needed for better confirmation of the role of EBRT.

    1988-01-01

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

    Full text: A serum TSH level of > 30 mU/L, which is necessary for reliable testing and efficient radioiodine therapy in patients with differentiated thyroid carcinoma, may be achieved by: a 4-6 weeks L-thyroxine withdrawal or by application of recombinant human TSH (rh TSH).The purpose of our study was to test the efficacy of 131-I therapy (RAIT) using recombinant human TSH (rhTSH) as an alternative in patients with differentiated thyroid carcinoma (DTC) in whom endogenous TSH stimulation was not an option due to the poor patient's physical condition during the hypothyroid state or due to the disease progression during L-thyroxine withdrawal. The study comprised 14 patients (12 females, 2 males, aged 63- 81, median 73 years), with histologically proven DTC, in whom the primary diagnosis was established 1993-2000, who already have undergone total or near-total thyroidectomy and who have received radioiodine ablation and 3-12 (median 6) RAITs after L-thyroxine withdrawal, with a cumulative dose ranging 15.65- 68.34 GBq. Patients were given 28 RAITs (7/14 patients received two, 2 received 3 and 1 received 4) while on L-thyroxine after rhTSH administration (rhTSH RAIT). RhTSH (0.9 mg, i.m.) was administered on two consecutive days, followed by 131-I therapeutic dose (5.2-7.6 GBq) administration on the third day and a post-therapeutic whole-body scan (PTWBS) 2-5 days later. The efficacy of rhTSH RAIT was evaluated by thyroglobuline (Tg) measurement 3 - 6 months after rhTSH RAIT. Serum TSH levels after rhTSH administration were 61 - 305 mU/l. Altogether 36 131-I-avid lesions were detected on PTWBS. In one patient who underwent two rhTSH RAITs a decrease of 131-I uptake in one lesion was seen on the second PTWBS. In all patients serum Tg concentrations were elevated before rhTSH RAIT (25 -17248 ng/ml). Three months after therapy serum Tg decreased by 24 -91% in 6 cases (4 patients), in 3 patients serum Tg stagnation was achieved, while in 7 cases the disease progressed

Methods Clinical data were collected from the thyroid unit database of the Antoine Lacassagne Institute. Results Of 1171 patients with thyroid cancer treated at our institution over the last 18 years, we retrospectively identified nine patients (0.8%, three women and six men, aged 34–81 years (median age: 70 years presenting with malignant thyroid tumor of median diameter 45 mm (range: 23–87 having venous obstruction of thyroid malignancy origin. Two patients underwent multimodal therapy. All other patients underwent external beam radiation therapy alone ± chemotherapy or palliative care. Ultrasound (US provided particularly useful information on venous involvement characteristics. Median survival was 7 months and median progression-free survival was 6 months. Survival in our series was worse than that of previously reported series despite diagnosis of vein involvement at an early stage in 2/3 cases using US. Conclusion Despite small numbers of patients, it seems that aggressive treatment modalities including surgery are required to improve survival. In our experience, US was a useful non-invasive method to describe tumor extensions to great veins of the neck (invasion versus compression, tumor thrombus versus blood clot and should be recommended to depict early venous invasion in cases of suspected thyroid malignancy.

Pupillary expansion devices were used in 31 (25.2%) PXF cases and 398 (8.4%) non-PXF cases (p < 0.0001). Capsular tension rings were used in 6 (4.9%) PXF cases and 55 (1.2%) non-PXF cases (p < 0.004). The following complications occurred more frequently in PXF cases: zonular dehiscence without vitrectomy (4 [3.3%] PXF cases vs 40 [0.8%] non-PXF cases p = 0.02), persistent inflammation (28 [24.1%] vs 668 [14.5%]; p = 0.007), and persistent intraocular pressure elevation (5 [4.3%] vs 68 [1.5%]; p = 0.03). Best corrected visual acuity (BCVA) improved in both groups after 1 month, but 87 (83.7%) PXF cases achieved postoperative BCVA better than or equal to 20/40 compared to 3991 (93.8%) non-PXF cases (p = 0.0003). There was no significant difference in the postoperative composite VFQ scores between PXF (82.1 ± 16.9) and non-PXF cases (84.2 ± 16.8, p = 0.09). Several complications occurred more frequently in the PXF group compared to the non-PXF group, and fewer PXF cases achieved BCVA better than or equal to 20/40. Despite this, both groups experienced similar improvement in vision-related quality of life after cataract surgery. Published by Elsevier Inc.

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

    Horner's syndrome is characterized by a combination of ipsilateral miosis, blepharoptosis, enophthalmos, facial anhidrosis, and iris heterochromia in existence of congenital lesions. The syndrome results from a disruption of the ipsilateral sympathetic innervation of the eye and ocular adnexa at different levels. Though rare, thyroid and neck surgery could be considered as possible causes of this clinical entity. We present a case of Horner's syndrome in a patient after total thyroidectomy and neck dissection for medullary thyroid cancer with neck nodal disease and attempt a brief review of the relevant literature.

    Full Text Available Background: Upper airway compromise due to tracheobronchial stenosis commonly occurs in patients with Wegener's Granulomatosis (WG. There is at present no consensus on the optimal management of this life-threatening condition. Objective: To assess the results of laryngo-tracheo-bronchoscopy, intralesional steroid therapy, laser surgery, and dilatation in managing obstructive tracheobronchial WG. Methods: Records of eighteen previously-untreated stridulous patients with obstructive tracheobronchial WG, treated between 2004 and 2006 were prospectively recorded on an airway database and retrospectively reviewed. Information about patient and lesion characteristics and treatment details were recorded. Treatment progress was illustrated using a timeline plot, and intervention-free intervals were calculated with actuarial analysis. Results: There were nine males and the average age at presentation was 40 (16 years [range 13–74]. There were thirteen patients with tracheal, and five patients with tracheal and bronchial lesions. The average tracheal lesion height was 8 (3 mm, located 23 (9 mm below the glottis. There were 1, 10 and 7 Myer-Cotton grade I, II and III lesions respectively. Mean intervention-free interval following minimally-invasive treatment was 26 (2.8 months. Following endobronchial therapy the median intervention-free interval was 22 months (p>0.8 vs. tracheal lesions. No patient required a tracheostomy or endoluminal stenting. Conclusions: Intralesional steroid therapy and conservative endoluminal surgery is an effective strategy for treating airway compromise due to active tracheal and bronchial WG, obviating the need for airway bypass or stenting. We recommend the combination of endotracheal dilatation, conservative laser surgery and steroid therapy as the standard of care for treating airway compromise due to obstructive tracheobronchial WG.

    We report herein a retrospective analysis of the results of 142 consecutive prolactinoma cases operated upon using an endoscopic endonasal trans-sphenoidal approach over a period of 6 years. Medical records of 142 cases were analysed with respect to indications for surgery, duration of hospital stay, early remission rates, failures and recurrence rates during a median follow-up of 36 months. On the basis of magnetic resonance imaging (MRI) data, 19 patients (13.4 %) had microadenoma, 113 (79.6 %) had macroadenoma, and the remaining 10 (7.0 %) had giant adenomas. Cavernous sinus invasion was identified in 25 patients by MRI and confirmed during surgery. Atypical adenoma was diagnosed in 16 patients. Sparsely granulated prolactin adenoma was identified in 99 patients (69.7 %). Our results demonstrate that male sex and higher preoperative prolactin levels are independent factors predicting persistent disease. The post-surgical complications are as follows: 2.8 % patients had meningitis, 2.1 % patients had postoperative cerebrospinal fluid leak and 2.1 % patients had panhypopituitarism. At the end of follow-up, 74.6 % patients went into remission. During follow-up period, five patients who had initial remission developed recurrence. Our series together with literature data suggest that an endoscopic endonasal trans-sphenoidal approach in the treatment of proloctinomas has a favourable rate of remission. According to the findings of this study, endoscopic endonasal trans-sphenoidal surgery might be an appropriate therapy choice for patients with prolactinoma who could not have been managed with recommended therapeutic modalities.

    Full Text Available ABSTRACT Objective: To investigate the relationship between preoperative vitamin D and albumin levels and postoperative quality of life in patients undergoing spinal surgery. Methods: Patients undergoing thoracic and lumbar spine surgery were evaluated in this prospective study. Their vitamin D and albumin levels were assessed before surgery and quality of life was measured by two questionnaires, Oswestry Disability Index (ODI and Scoliosis Research Society - 22 (SRS-22, one year after the procedure. Data on infection occurrence and healing time were collected. Preoperative nutritional values and patients’ quality of life were analyzed using the chi-square test and ANOVA for albumin and vitamin D, respectively. The relationship among nutritional status, healing time, and the occurrence of infection was evaluated by the Pearson correlation coefficient. Results: Forty-six patients were included and their mean nutritional values were 19.1 (6.6 ng/mL for vitamin D and 3.9 (0.6 g/dL for albumin [mean (standard deviation]. No association was found between vitamin D and quality of life of patients measured by ODI (p=0.534 and SRS-22 (p=0.739 questionnaires. There was also no association between albumin levels and quality of life measured by ODI (p=0.259 and SRS-22 (p=0.076 questionnaires. No correlation was found between the healing time or occurrence of infection and nutritional values. Conclusions: There was no association between vitamin D and albumin levels and the surgical result, according to the patient’s perception, besides the occurrence of complications with the surgical wound.

    To report the results from the first iteration of the European Observatory of Cataract Surgery, which was initiated to track changes in surgical, antiseptic, and antibiotic practices in cataract surgery over the coming years. Practicing European cataract surgeons (n = 479). Internet-based declarative questionnaire or telephone questionnaire. The questionnaire comprised 37 questions divided into 8 categories as follows: screening, surgeon profile, surgical procedure used, product use before arrival at the operating room, techniques for mydriasis and anesthesia, product use during the surgery, product use after the patient leaves the operating room, and surgeon's attitude to guidelines. Cataract surgeons (n = 2700) were initially contacted, of whom 479 (17.7%) were included in the survey. The current baseline survey revealed considerable variation between countries in their implementation of infectious postoperative endophthalmitis (IPOE) prophylaxis. In some countries, adoption of intracameral cefuroxime is almost universal, whereas in others, the use of such prophylaxis is below one half. When intracameral cefuroxime is used, it is generally cefuroxime powder designed for parenteral use. A preparation specifically registered for intracameral use is now available, and this formulation is more commonly used in countries in which intracameral cefuroxime was most widely adopted. The baseline results from this ongoing survey suggest a considerable level of heterogeneity between European countries in IPOE prophylaxis. Further iterations of this survey will monitor whether a consensus begins to emerge. This work was supported by Laboratoires Théa, under the supervision of the expert group.

    Limited data have been reported on bariatric surgery within a large, high-volume regional multicenter integrated healthcare delivery system. Review clinical characteristics and short- and intermediate-term outcomes and adverse events from a bariatric surgery program within an integrated healthcare delivery system. Single high-volume, multicenter regional integrated healthcare delivery system. Adult patients who underwent primary bariatric surgery during 2010-2011 were reviewed. Clinical characteristics, outcomes, and weight loss results were extracted from the electronic medical record. A total of 2399 patients were identified within the study period. The 30-day rates of clinical outcomes for Roux-en-Y gastric bypass (RYGB; n = 1313) and sleeve gastrectomy (SG; n = 1018) were 2.9% for readmission, 3.0% for major complications, .8% for reoperation, and 0% for mortality. One-year and 2-year weight loss results were as follows: percent weight loss (%WL) was 31.4 (±SD 8.5) and 34.2±12.0% for SG and 34.1±9.3 and 39.1±11.9 for RYGB; percent excess weight loss (%EBWL) was 64.2±18.0 and 69.8±23.7 for SG and 68.0±19.3 and 77.8±23.7 for RYGB; percent excess body mass index loss (%EBMIL) was 72.9±21.0 and 77.7±22.4 for SG and 76.6±22.1% and 85.6±21.6 for RYGB. Follow-up for each procedure at 1 year was 76% for SG (n = 778) and 80% for RYGB (n = 1052) and at 2 years was 65% for SG (n = 659) and 67% for RYGB (n = 875). A large regional high-volume multicenter bariatric program within an integrated healthcare delivery system can produce excellent short-term results with low rates of short- and intermediate-term adverse outcomes.

    This book is based on the authors' extensive practical experience in the use of modern ultrasound, and other radiological methods, in the diagnosis of thyroid diseases. The authors have analyzed more than 100,000 ultrasound examinations performed between 1995 and 2008 in patients with thyroid and parathyroid disease, as well as many thousands of diagnostic and therapeutic ultrasound-guided minimally invasive procedures. The opening chapters include discussion of current ultrasound techniques, pitfalls, and the specifics of ultrasound examination of the thyroid in children. Detailed attention is then devoted to findings in the normal thyroid and in the presence of diffuse and focal changes. Further chapters focus on such topics as ultrasound examination after thyroid surgery and ultrasound diagnosis of parathyroid disease, recurrent goiter, and neck masses. Ultrasound-guided minimally invasive techniques, such as fine-needle aspiration biopsy, percutaneous laser ablation, and ethanol and glucocorticoid injections, are considered in depth. This up-to-date and richly illustrated book will interest and assist specialists in ultrasound diagnostics, radiologists, endocrinologists, and neck surgeons. (orig.)

    Surgery followed by radioiodine is a mainstay of treatment for thyroid cancers of follicular origins. However, about 5% of the thyroid cancers are non-operable and/or radioiodine-refractory diseases, which are either locally advanced or metastatic and result in a survival of less than 5 years. How to treat this population of thyroid cancer patients becomes a critical issue requiring further understanding of the tumor's genetic information. We used formalin-fixed paraffin-embedded specimens of 22 fatal thyroid cancers and their corresponding non-tumor parts, if available, to yield genomic DNA, and applied the Ion Torrent™ Personal Genome Machine (IT-PGM) System (Life Technologies), a next generation sequencing technology, to interrogate 740 mutational hotspots in 46 oncogenes. We further validated the results by conventional direct sequencing. We confirmed 21 mutations of 11 oncogenes in the 22 fatal thyroid cancer samples. Among them, the MET p.N375S and MLH1 p.V384D mutations, each was detected in two cases, and has rarely been found to be involved in thyroid cancer pathogenesis before. We also identified homozygous PDGFRA p.V824V mutation in eight out of the 22 cases, while the non-tumor counterparts carried heterozygous PDGFRA p.V824V mutation. We noted that the Ion Torrent technique unfortunately showed high false positive rates for detecting EGFR mutations in thyroid cancers. The extensive genetic studies provide new insights to future targeted therapy in these patients. IT-PGM proved to be valuable for comprehensively searching genetic mutations in potentially fatal thyroid cancers. Copyright © 2017. Published by Elsevier B.V.

    2014-01-01

    Hashimoto thyroiditis (HT), now considered the most common autoimmune disease, was described over a century ago as a pronounced lymphoid goiter affecting predominantly women. In addition to this classic form, several other clinico-pathologic entities are now included under the term HT: fibrous variant, IgG4-related variant, juvenile form, Hashitoxicosis, and painless thyroiditis (sporadic or post-partum). All forms are characterized pathologically by the infiltration of hematopoietic mononuclear cells, mainly lymphocytes, in the interstitium among the thyroid follicles, although specific features can be recognized in each variant. Thyroid cells undergo atrophy or transform into a bolder type of follicular cell rich in mitochondria called Hürthle cell. Most HT forms ultimately evolve into hypothyroidism, although at presentation patients can be euthyroid or even hyperthyroid. The diagnosis of HT relies on the demonstration of circulating antibodies to thyroid antigens (mainly thyroperoxidase and thyroglobulin) and reduced echogenicity on thyroid sonogram in a patient with proper clinical features. The treatment remains symptomatic and based on the administration of synthetic thyroid hormones to correct the hypothyroidism as needed. Surgery is performed when the goiter is large enough to cause significant compression of the surrounding cervical structures, or when some areas of the thyroid gland mimic the features of a nodule whose cytology cannot be ascertained as benign. HT remains a complex and ever expanding disease of unknown pathogenesis that awaits prevention or novel forms of treatment. Copyright © 2014 Elsevier B.V. All rights reserved.

    I have studied endoscopic surgery for breast diseases and have studied 3-dimensional computed tomographic lymphography for sentinel node biopsy. In this chapter, I introduced my works of the endoscopic breast surgery. I devised a new endoscopic operation for breast diseases: video-assisted breast surgery. The goal of endoscopic breast surgery is to obtain better cosmetic outcomes. A 2.5-cm axillary or periareolar skin incision was made. Under video assistance, the mammary gland was partially or totally resected with a gasless method. A transaxillary retromammary route approach was used even for tumors of the medial aspect of the breast. For malignant tumors, sentinel node biopsy was performed, and axillary nodes were dissected. Breast reconstruction was performed simultaneously. Cosmetic results were assessed with a standard 4-step method and the method described in the Japanese guidelines for breast-conserving therapy. More-objective quantitative methods are breast retraction assessment, the method reported by the research group of Sawai, and ABNSW, a 5-item, 4-step method that evaluates asymmetry (A), breast shape (B), nipple deformation (N), skin condition (S), and wound scar (W). The cosmetic results in endoscopic breast surgery showed that almost 90% of patients received a total score greater than 11 points, which indicates that this video-assisted breast surgery achieves better cosmetic results. The reconstruction methods in breast-conserving therapy are mammary gland translocation, the lateral tissue flap filling method, and absorbable thread mesh filling. The filling methods are superior to the translocation at the point of less deformation of the breast shape. Reconstruction with filling methods will allow wider excision of the mammary gland while achieving better cosmetic results. Video-assisted breast surgery is less invasive, produces no scars on the breast skin, and achieves better aesthetic outcomes for patients with breast cancer. It also improves

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

    Purpose: To retrospectively evaluate treatment results and toxicity following a combined approach consisting of neoadjuvant radiochemotherapy and radical surgery in advanced adenocarcinoma of the esophagus and gastroesophageal junction. Patients and Methods: Between 2005 and 2009, a total of 41 consecutive patients with newly diagnosed nonmetastatic adenocarcinoma of the esophagus and the esophagogastric junction were evaluated, of whom 23 received neoadjuvant radiochemo-therapy (RCT). A total dose of 50.4 Gy with 2 cycles of simultaneous cisplatin/5-fluorouracil (FU) or Taxol/FU-chemotherapy were applied. A radical transthoracic subtotal esophageal and proximal gastric resection through a right thoracoabdominal laparotomy with intrathoracic anastomosis was performed 6-8 weeks following RCT. This was combined with a two-field lymphadenectomy of mediastinal and abdominal lymph nodes. Standard histopathological evaluation included the application of regression grading according to Werner and Hoefler. Toxicity was recorded on the basis of CTC criteria; survival curves were calculated according to Kaplan-Meier. V10, V15, and V20 data were correlated with pulmonary toxicity. Results: Overall survival for all 23 patients was 61% at 3 years. Of the original 23 patients, 18 (78%) patients proceeded to radical surgery. Reasons for no surgery included advanced age of 79, 82, and 86 years (n = 3), severe comorbidity (n = 1), and progression during radiochemotherapy (n = 1). Surgical morbidity (grade 3-4) and mortality rates were 35% and 6%, respectively. Resurgery was necessary in 3 cases (18%). Clear resection margins were achieved in 17 of 18 patients (94%). Twelve of 18 (67%) patients initially diagnosed with T3 tumors and 3 of 3 patients with T4 tumors experienced downstaging. The ypN0 rate was 12 of 18 patients (67%). Out of a total of 18 patients, regression grading revealed < 10% viable cells in 8 (44%) including 3 cases (17%) with complete regression, 10-50% viable

    Full Text Available Background: Struma testis is a rare entity, and there are only few reports on the malignant transformation of a testicular teratoma to papillary thyroid carcinoma in the literature. In this report, we describe the malignant transformation of struma testis with distant lung metastasis associated with trisomy 17 and a coexisting papillary microcarcinoma in the thyroid. Case Report: A 56-year-old man presented after a left orchiectomy for an undescended left testicle. Pathologic examination identified a monodermal teratoma composed of thyroid parenchyma and associated with a 1.7-cm papillary thyroid carcinoma. Further evaluation showed a pulmonary mass on a chest CT scan. Total thyroidectomy revealed a 0.5-mm focus of papillary thyroid cancer, and removal of the lung mass confirmed metastatic papillary thyroid cancer. Array-comparative genomic hybridization of both tumors showed trisomy 17 in the struma testes and the lung metastasis. The patient responded well to radioactive iodine ablation and has no evidence of cancer 3 years later. Conclusion: To our knowledge, this is the first case of papillary thyroid cancer in struma testes metastatic to the lung. It highlights the difficulties in treating these patients. Surgery to remove cancer foci, followed by radioactive iodine ablation, resulted in an excellent response in our patient. Interestingly, trisomy 17, which has so far been observed only in noninvasive thyroid nodules, was associated with pulmonary metastasis in our patient.

    Objective: To study the pathological morphology of thyroid specimen after thyroid arteries embolization. In order to select appropriate size of embolizing granules, the diameters of thyroid arteries in Graves' disease were measured. Methods: Multiple slides of embolized thyroid tissues from superior pole, body and inferior pole of the resected thyroid glands were made. After being embedded and stained, pathological morphology was observed and diameters of arteries in various parts of thyroid glands were measured under microscopy. Results: Pathological examination of thyroid glands showed that superior and inferior thyroid arteries and most of their branches were embolized with ischemic necrosis and fibrosis in the embolized thyroid tissue. Follicular epithelium appeared as flat or cubic shapes with colloid reduction. Average diameter of main branches of superior artery was 440-550 μm and that of inferior artery was 300-375 μm. The diameters of capillary network in the thyroid body was 120-250 μm, and the non-embolized ones was 40-110 μm. The diameter of isthmus was 130-150 μm. Conclusions: Pathological morphology of Graves' disease after thyroid arteries embolization showed that the excretion of thyroid glands would be decreased and equivalents to subtotal thyroidectomy

  1. Robot-Assisted Transaxillary Thyroid Surgery—Feasibility and Safety of a Novel Technique

    Full Text Available Developments in technology have led to a rapid progress in robotic endocrine surgery applications. With the advent of minimally invasive techniques in thyroid surgery, robot-assisted transaxillary thyroid surgery (RATS has emerged as one of the most promising approaches. Its main advantages are improved cosmetic outcome, avoiding cervical incisions, thereby increasing patient satisfaction, and improved visualization, arms articulations, and precision, resulting in fewer surgical complications. The main disadvantages are potential new injuries to the brachial plexus, esophagus, and trachea, longer operative time, and increased cost compared to conventional thyroidectomy. In skilled hands, RATS is a safe alternative to conservative thyroidectomy and should be presented to patients with aesthetic concerns. As with any new emerging technique, careful patient selection is crucial, and further evidence must be sought to confirm its indications over time.

    Incidence rate of differentiated thyroid carcinoma in teenager is not high. It has some different characteristics compared to adult differentiated thyroid carcinoma. Such as larger tumor at diagnosis; greater prevalence of neck lymph node and distant metastases at diagnosis; more sodium-iodide symporter expression; high recurrence rate but higher overall survival rate. 131 I administration to remove residual thyroid tissue and treat metastases is still one of the important approaches after surgery.

    We present a new approach for BCS which we have named as the Lateral Oncoplastic Breast Surgery (LOBS) approach. Patients with biopsy proven breast cancer or phyllodes tumors in the outer quadrants of the breast were selected. The patients were operated in the lateral position using the principles of a Level 1 oncoplastic technique. 106 patients (93 breast cancer; 13 phyllodes tumor) were operated using this technique. For patients with breast cancer the mean tumor size was 2.7 cms. 3 patients had a positive margin. The mean tumor size for phyllodes tumors was 6.7 cms. Surgical site infections (15 patients), marginal skin necrosis (2 patients) and superficial NAC necrosis (1 patient) were observed. Although the mean follow up was only 355.8 days there were no early detected recurrences. LOBS is a new approach for BCS which offers distinct advantages. The short term results, both oncological and aesthetic, are encouraging. A new approach for performing oncoplastic breast conserving surgery (BCS) is described and the short term results of our first 106 cases are presented. Advantages of this approach over conventional techniques are reviewed. Copyright © 2017 Elsevier Inc. All rights reserved.

    From january 1994 to january 1995 seven patients were treated with conservative surgery in association to postoperative HDR brachytherapy through Micro-Selectron HDR. Four patients were male and three female, the ages ranged from 20 to 60 years old and the main site of the tumor were at the extremities and just one had a perineal lesion. The follow up ranged from 4 to 24 months. Most of the implants were done through single plane technic. Definition of the treatment volume was based on CT scans and metallic clips inserted during the surgery. The prescribed dose was at 10mm from the implant plane. The patient with perineal lesion had a volumetric implant and the dose prescription was based on Paris System, in which the total volume of the tumor bed must be included in a 85% isodose curve. The number of catheters used ranged from 6 to 14 and the active length from 20 to 150mm, placed intraoperatively. The volumetric implant was performed through perineal template to guide the needles in number of nine and an active length of 60mm. The prescribed dose ranged from 20 to 25Gy when associated with EBRT and 30 to 35Gy when brachytherapy alone was used. Results: All patients had local control. Acute complications were observed only in the skin, limited to mild erytema and dry descanation. Conclusions: Although the number of the patients is small, this procedure has been shown to be effective in local control when associated to conservative surgery, can be easily and safely done and gives the possibilities of dose optimization

    The purpose of the study was to investigate which supervisory approach afforded the most efficient learning method for undergraduate students in oral and maxillofacial surgery (OMS) using a computerised third molar surgery simulator. Fifth year dental students participated voluntarily in a randomised experimental study using the simulator. The amount of time required and the number of trials used by each student were evaluated as a measure of skills development. Students had the opportunity to practise the procedure until no further visible improvements were achieved. The study assessed four different types of supervision to guide the students. The first group was where they were supported by a teacher/specialist in OMS, the second by a teaching assistant, the third group practised without any supervision and the fourth received help from a simulator technician/engineer. A protocol describing assessment criteria was designed for this purpose, and a questionnaire was completed by all participating students after the study. The average number of attempts required to virtually remove a third molar tooth in the simulator was 1.44 times for the group supervised by an OMS teacher; 1.5 times for those supervised by a teaching assistant; 2.8 times for those who had no supervision; and 3.6 times when support was provided only by a simulator technician. The results showed that the most efficient experience of the students was when they were helped by an OMS teacher or a teaching assistant. In a time and cost-effective perspective, supervision by a teaching assistant for a third molar surgery simulator would be the optimal choice. © 2013 John Wiley & Sons A/S.

    The study set out to evaluate the efficacy of two antibiotic prophylaxis regimens in patients with facial fractures admitted to the Oral and Maxillofacial Surgery and Traumatology services of the Onofre Lopes University Hospital attached to the Federal University of Rio Grande do Norte in the period from December 2011 to December 2012. The sample consisted of 74 patients divided into two groups, GI with forty-three patients and GII with 32. Both groups received 2 g of cefazolin, 20 minutes before surgery. The postoperative protocol for each group was randomly determined; group I (single dose) received no antibiotics after surgery but group II (24 h dosage) received 1 g of cefazolin every 6 hours for 24 hours. Postoperative infection incidence was 9.3% (seven patients), six patients in Group I and one in Group II. 85% of the infections were in mandibular fractures. Results were presented qualitatively and quantitatively and the Chi square test (taking the value for p to be < 0.05) showed no statistically significant differences in the efficacies of the two regimens in the comparisons made between the cases of fractures in the upper and middle thirds of the face with those in the lower third (mandibular fractures). Considering mandibular fractures alone, Group II proved to be more efficacious with a p value of 0.02. However, to confirm the tendency shown in the mandibular fracture treatments whereby prolonging antibiotic administration for 24 hours appeared to be beneficial, research needs to be done with much larger sample groups.

    The aim of this study was to evaluate the long-term oncologic outcome after oncoplastic surgery (OPS). OPS combines wide tumor excision with reduction mammoplasty techniques thus extending breast conserving surgery to large tumors that might else be proposed a mastectomy. Little data are available about the oncologic results for breast conserving surgery of these larger tumors. From January 2004 until March 2016, a total of 350 oncoplastic breast reductions were prospectively entered into a database. Patients were included if their breast reshaping included a reduction mammoplasty with skin excision (Level 2 oncoplastic techniques). Histologic subtypes were: invasive ductal carcinoma in 219 cases (62.6%), ductal carcinoma in situ (DCIS) in 88 cases (25.1%), and invasive lobular carcinoma in 43 (12.3%) cases. Seventy-three of the invasive cancers (27.9%) received neoadjuvant chemotherapy. The mean resection weight was 177 grams. The mean pathological tumor size was 26 mm (range 0-180 mm) and varied from 23 mm (4-180 mm) for invasive cancers to 32 mm (0-100 mm) for DCIS. Specimen margins were involved in 12.6% of the cases; 10.5% of invasive ductal, 14.7% of DCIS, and 20.9% of invasive lobular. The overall breast conservation rate was 92% and varied from 87.4% for DCIS to 93.5% for the invasive cancers. Thirty-one patients (8.9%) developed one or more postoperative complications, inducing a delay in postoperative treatments in 4.6% of patients. The median follow up was 55 months. The cumulative 5-year incidences for local, regional, and distant recurrences were 2.2%, 1.1%, and 12.4%, respectively. Oncoplastic breast reductions allow wide resections with free margins and can be used for large cancers as an alternative to mastectomy.

    Cardiac adverse events (CAEs) are relatively infrequent, but highly lethal, after noncardiac operations. The value of available risk scoring systems is uncertain and these systems can be outdated. We used the Patient Safety in Surgery Study database to develop and test a model to predict patient risk for CAEs after general and vascular surgical operations. As part of the Patient Safety in Surgery Study, following the National Surgical Quality Improvement Program's protocol, multiple demographic, preoperative, perioperative, and outcomes variables were measured during a 3-year period. Data from 128 Veterans Affairs medical center hospitals and from 14 academic medical centers on 183,069 patients were used in a logistic regression analysis to model multivariable predictors of serious CAEs (cardiac arrest or acute myocardial infarction within 30 days of operation). CAEs occurred in 2,362 patients (1.29%) and of these, 59.44% expired. Multivariable stepwise logistic regression identified 20 independent predictors of CAEs, which excluded most cardiac-specific risk factors. The most important multivariable predictors of CAE were American Society of Anesthesiologists physical status classification, work relative value units of the most complex procedure, age, and type of operation. A risk prediction scoring system using the logistic regression odds ratios proved to be a useful prediction tool when tested using a random sample from the database. CAEs after noncardiac operations are relatively infrequent but highly lethal. Operation type and urgency and American Society of Anesthesiologists physical status assessment are important independent predictors of cardiac morbidity, but angina, recent MI, and earlier cardiac operation are not. A prediction scoring system based on the Patient Safety in Surgery Study multivariable odds ratios is likely to be predictive of future events in a similar population requiring noncardiac procedures. This risk model can also serve as a tool

    In this document the case of a 66-year old woman is presented, with record of multi nodular goiter of 5 year of evolution, which is derived to scan ultrasound office to make a puncture-aspiration with thin needle because of the growth of nodular thyroid injuries. The ultrasound scan examination made before the puncture determine multiple dominant nodules of hyperplasia aspect between 15 and 25 mm of diameter and a small nodule of 6 mm suspected proliferate process. Despite its size, it was decided to include small nodule in injuries to a biopsy. The cytological study reveals nodular hyperplasia with carcinoma in the small nodule of 6 mm. A thyroidectomy is practiced on the patient. The deferred histological study of the thyroid gland confirms the finding of multi-nodular goiter with a small focus of papillar carcinoma. The ganglions examined were negative in the deferred examination [es

    Delphi Panel expert panel consensus and narrative literature review. To obtain expert consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (anterior cervical disc fusion (ACDF) and cervical total disc replacement (CTDR)). Spine surgery in ambulatory settings is becoming a preferred option for both patients and providers. The transition from traditional inpatient environments has been enabled by innovation in anesthesia protocols and surgical technique, as well as favorable economics. Studies have demonstrated that anterior cervical surgery (ACDF and CTDR) can be performed safely on an outpatient basis. However, practice guidelines and evidence-based protocols to inform best practices for the safe and efficient performance of these procedures in same-day, ambulatory settings are lacking. A panel of five neurosurgeons, three anesthesiologists, one orthopedic spine surgeon, and a registered nurse was convened to comprise a multidisciplinary expert panel. A three-round modified-Delphi method was used to generate best-practice statements. Predetermined consensus was set at 70% for each best-practice statement. A total of 94 consensus statements were reviewed by the panel. After three rounds of review, there was consensus for 83 best-practice statements, while 11 statements failed to achieve consensus. All statements within several perioperative categories (and subcategories) achieved consensus, including preoperative assessment (n = 8), home-care/follow-up (n = 2), second-stage recovery (n = 18), provider economics (n = 8), patient education (n = 14), discharge criteria (n = 4), and hypothermia prevention (n = 6). This study obtained expert-panel consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (ACDF/CTDR). Given a paucity of guidelines and a lack of established care pathways for ACDF/CTDR in same

    Nasal airway obstruction is a frequently-encountered problem, often secondary to inferior turbinate hypertrophy. Medical treatment can be beneficial but is inadequate for many individuals. For these refractory cases, surgical intervention plays a key role in management. The authors evaluate the current trends in surgical management of inferior turbinate hypertrophy and review the senior author's (SS) preferred technique. A questionnaire was devised and sent to members of the American Society for Aesthetic Plastic Surgery (ASAPS) to determine their preferred methods for assessment and treatment of inferior turbinate hypertrophy. One hundred and twenty-seven physicians responded to the survey, with 85% of surveys completed fully. Of the responses, 117 (92%) respondents were trained solely in plastic surgery and 108 (86.4%) were in private practice. Roughly 81.6% of respondents employ a clinical exam alone to evaluate for airway issues. The most commonly-preferred techniques to treat inferior turbinate hypertrophy were a limited turbinate excision (61.9%) and turbinate outfracture (35.2%). Based on the results of this study, it appears that limited turbinate excision and turbinate outfracture are the most commonly-used techniques in private practice by plastic surgeons. Newer techniques such as radiofrequency coblation have yet to become prevalent in terms of application, despite their current prevalence within the medical literature. The optimal method of management for inferior turbinate reduction should take into consideration the surgeon's skill and preference, access to surgical instruments, mode of anesthesia, and the current literature.

    The high incidence and low mortality of breast cancer surgery has led to an increasing emphasis on the cosmetic outcome of surgical treatment. Advances in aesthetic evaluation, as well as surgical planning and outcome prediction, have been investigated by using geometrically precise 3D modelling of the breast surface prior to surgery and after the procedure. However, existing solutions are based on expensive site specific setups and remain weakly validated. In this paper, we explore the possibility of using low-cost RGBD cameras as an affordable and mobile system for breast surface reconstruction. The methodology relies on sensor calibration, uncertainty-driven point filtering, dense reconstruction and subsequent multi-view joint optimization to diffuse residual pose errors. Results from a phantom study, with ground truth obtained through commercially available scanners, indicate that the approach is promising with RMS errors in order of 2 mm. A clinical study shows the practical applicability of our method and compares favourably to high-end scanning solutions.

    Background Bariatric surgery is one of the few effective treatments for morbid obesity but the weight loss and other health related outcomes for this procedure in large, diverse adolescent patient populations are not well characterized. Objective To analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. Setting BOLD data is collected from 423 surgeons at 360 facilities in the United States. Methods Main outcome measures included anthropometric and comorbidity status at baseline (n=890) and at 3 (n=786), 6 (n=541), and 12 (n=259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) age 11-to-19 years were included in the analyses. Results The overall one year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 kg versus 20 kg, Psurgery types (Psurgery. There were a total of 45 readmissions among gastric bypass patients and 10 among adjustable gastric band patients with 29 and 8 reoperations required, respectively. Conclusions Weight loss at 3-, 6-, and 12-months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related comorbidities in morbidly obese adolescents for at least 1 year. PMID:22542199

    To explore the association of American Society of Anesthesiologists (ASA) classification with cataract surgery outcomes. Five Veterans Affairs Medical Centers, United States. Retrospective observational cohort study. The study analyzed the outcomes of cataract surgery cases. Corrected distance visual acuity (CDVA), unanticipated events, and vision-related quality of life (VRQL) were assessed using the National Eye Institute Visual Function Questionnaire (NEI-VFQ), comparing ASA classes I through IV. For some analyses, ASA classes I and II were designated as Group A and ASA classes III and IV were designated Group B. Of the 4923 cases, 875 (17.8%) were in Group A, 4032 (81.9%) were in Group B, and 16 (0.3%) had missing data. The mean CDVA and mean composite NEI-VFQ score improved after cataract surgery in both groups (P < .0001); however, Group A had a better mean postoperative CDVA and postoperative VFQ composite scores than Group B (P < .0001, both outcomes). A higher ASA class was associated with an increased risk for 2 unanticipated events; that is, clinically significant macular edema (CSME) (Group A: 4 [0.47%] versus Group B: 50 [1.28%]; adjusted odds ratio [OR], 3.02; 95% confidence interval [CI], 1.02-13.05; P = 0.04) and readmission to the hospital within 30 days (2 [0.23%] versus 56 [1.41%]; OR, 8.26; 95% CI, 1.71-148.62; P = .004) CONCLUSIONS: Among United States veterans, the ASA classification could be an important predictor of VRQL and visual outcomes. In this cohort, it was associated with an increased risk for 2 serious unanticipated events-CSME and readmission to the hospital-both costly, unwanted outcomes.

    2015-01-01

    Introduction: Giant fibroadenoma (GFA) of the breast is defined as fibroadenoma larger than 5 cm, usually presenting unilaterally and manifesting as breast asymmetry or deformity of the breast. Material and Methods: A retrospective database search was done of all patients with giant fibroadenoma who underwent surgery for GFA in the breast center of Hanover Medical School between 2007 and 2014; all patients with GFA were followed up. Data were analyzed with regard to tumor and patient characteristics and esthetic outcome. Results: A total of 13 patients with symptomatic GFA underwent surgery between 2007 and 2014. Mean patient age was 21.2 years (range 14–31 years). In 8 of 13 patients the tumor had resulted in breast deformity and/or breast asymmetry. Average size of the mass was 10.2 cm (range 8.5–12 cm) and average weight was 203.6 g (range 151.2–323.5 g). Initial clinical suspicion of GFA was confirmed by ultrasound examination. Preoperative core biopsy revealed fibroadenoma in 8/13 cases, cellular fibroepithelial lesions with a differential diagnosis of benign phyllodes tumor in 3 cases and unspecific histological findings in the remaining 2 cases. Conclusion: Excision was done using an inframammary or periareolar approach without reconstructive plasty. The cosmetic results were good, as were the outcomes on follow-up. We therefore favor this surgical technique to treat giant fibroadenoma of similar size to those described above. PMID:26500369

    Full Text Available "nBackground: Degenerative spondylolisthesis is a common disease of the lumbar spine especially in older ones. The disease represents a challenge to the treating physician. At present, for those patients that deteriorate clinically, there are many proposed algorithms for the surgical treatment. This before and after study was undertaken to assess the surgical results of decompression and instrumented posterolateral fusion in these patients. "nMethods: The study population consisted of 23 patients who had undergone no prior surgery for degenerative spondylolisthesis on the lumbar spine. These patients were treated by decompression, bilateral posterolateral fusion, and segmental (pedicle screw instrumentation with mean follow-up of 29 months (range, 13-73 months. Finally, The clinical results were evaluated for all patients by means of an Oswestry Disability Index (ODI version 2.1, the Henderson's functional capacity, and persistence of leg symptoms, low back pain or claudication. Mann-Whitney and Chi-Square tests were used to assess the average values and comparison, respectively. "nResults: Henderson's functional capacity at the last visit session was excellent in 14 (60.9%, good in 7 (30.4%, fair in 2 (8.7% cases. ODI decreased from 72.2% (50-88% preoperatively to 14.4% (0-54% at the latest follow-up visit. A history of leg pain or claudication was correlated significantly with the amount of decline in ODI score and Henderson's functional capacity (p<0.05. "nConclusion: In spite of limited number of our patients, decompressive surgery plus instrumented posterolateral fusion is a safe, reliable, and satisfactory procedure for treating degenerative lumbar spondylolisthesis. This procedure may be done when conservative treatment was failed and psychological problems can be ruled out.

    Altered thyroid function tests as a consequence of illness have been recognized for many years, yet the cause and clinical implications remains uncertain. The routine testing of thyroid function in hospitalized patients should be discouraged, as the results are less predictive of primary thyroid disease than in ambulatory patients. Clinicians should be aware of the methods used for thyroid function testing, as the effect of illness on thyroid function varies among the different tests. The most commonly used free T4 assays likely are influenced significantly by nonthyroidal illness. Advances in understanding the basic mechanisms of thyroid hormone metabolism and thyroid hormone action have given insights into the changes in thyroid function tests as a consequence of nonthyroidal illness. In the future, thyroid hormone receptor isoform-specific agonists and antagonists may allow for more specific treatment of select patients with nonthyroidal illness syndrome.

    Within the domain of craniomaxillofacial surgery, orthognathic surgery is a special field dedicated to the correction of dentofacial anomalies resulting from skeletal malocclusion. Generally, in such cases, an interdisciplinary orthodontic and surgical treatment approach is required. After initial orthodontic alignment of the dental arches, skeletal discrepancies of the jaws can be corrected by distinct surgical strategies and procedures in order to achieve correct occlusal relations, as well as facial balance and harmony within individualized treatment concepts. To transfer the preoperative surgical planning and reposition the mobilized dental arches with optimal occlusal relations, surgical splints are typically used. For this purpose, different strategies have been described which use one or more splints. Traditionally, these splints are manufactured by a dental technician based on patient-specific dental casts; however, computer-assisted technologies have gained increasing importance with respect to preoperative planning and its subsequent surgical transfer. In a pilot study of 10 patients undergoing orthognathic corrections by a one-splint strategy, two final occlusal splints were produced for each patient and compared with respect to their clinical usability. One splint was manufactured in the traditional way by a dental technician according to the preoperative surgical planning. After performing a CBCT scan of the patient's dental casts, a second splint was designed virtually by an engineer and surgeon working together, according to the desired final occlusion. For this purpose, RapidSplint, a custom-made software platform, was used. After post-processing and conversion of the datasets into .stl files, the splints were fabricated by the PolyJet procedure using photo polymerization. During surgery, both splints were inserted after mobilization of the dental arches then compared with respect to their clinical usability according to the occlusal fitting. Using

    The article is based on the treatment results of 44 patients with follicular tunor of thyroid gland. A staged morphological assessment of thyroid nodes was performed for all patients: in case of preoperative fine-needle biopsy, urgent intraoperative study and according to results of final histological research. The urgent histological study of surgical material was conducted for 44 patients with diagnosis "follicular tumor" according to fine-needle biopsy. The data of final histological study were matched with findings of intraoperative research. A micro-follicular adenoma was detected in 22 patients (50%) and 6 (13,6%) patients had this diagnosis combined with autoimmune thyroiditis. The general part of patients didn't changed in final study, but the rate of diagnosis "micro-follicular adenoma against the background of autoimmune thyroiditis" increased. Papillary carcinoma was revealed in 5 (11,4%) patients and follicular cancer had 4 (9,1%) patients detected in intraoperative study and 3 (6,8%) more patients according to data of final research. The histopathologic feature of colloid goiter was observed in 7 (15,9%) cases and a part of such patients reduced to 6,8% during final study. One of the patients (2,3%) had final diagnosis "oncocytoma". In case of thyroid nodules detection the needle biopsy should be carried out regardless to the size of nodule. The authors recommended performing the surgery with the urgent histological study in case of undetermined histological report. The following surgical strategy was specified by the results of the urgent histological report.

  3. Thyroid disease: thyroid function tests and interpretation

    African Journals Online (AJOL)

    Diseases of the thyroid are among the most prevalent of medical conditions, especially in women, but the symptoms can be relatively nonspecific or mild. For this reason, clinicians have been placing increased reliance on the laboratory for assistance in the diagnosis of thyroid disorders. In the 1950s, only one thyroid test ...

    In some countries, in order to perform rhTSH-aided thyroid remnant ablation (TRA) after surgery, it is generally necessary to confirm that thyroidectomy has been almost complete. Otherwise, the nuclear medicine specialist will not administer a high radioiodine dose because it might be hazardous due to the possibility of thyroid remnant actinic thyroiditis. Considering this, it would be necessary to use two rhTSH kits (one for diagnostic purposes and the other one to administer the 131 I dose). In this study, we used an alternative protocol for TRA with the use of one kit of rhTSH in twenty patients diagnosed with low risk papillary thyroid carcinoma. All patients had negative titers of anti-thyroglobulin antibodies. Successful thyroid remnant ablation was confirmed with an undetectable rhTSH stimulated thyroglobulin level ( [es

    To evaluate the cost-effectiveness of bariatric surgery in Italy from a third-party payer perspective over a medium-term (10 years) and a long-term (lifetime) horizon. A state-transition Markov model was developed, in which patients may experience surgery, post-surgery complications, diabetes mellitus type 2, cardiovascular diseases or die. Transition probabilities, costs, and utilities were obtained from the Italian and international literature. Three types of surgeries were considered: gastric bypass, sleeve gastrectomy, and adjustable gastric banding. A base-case analysis was performed for the population, the characteristics of which were obtained from surgery candidates in Italy. In the base-case analysis, over 10 years, bariatric surgery led to cost increment of EUR 2,661 and generated additional 1.1 quality-adjusted life years (QALYs). Over a lifetime, surgery led to savings of EUR 8,649, additional 0.5 life years and 3.2 QALYs. Bariatric surgery was cost-effective at 10 years with an incremental cost-effectiveness ratio of EUR 2,412/QALY and dominant over conservative management over a lifetime. In a comprehensive decision analytic model, a current mix of surgical methods for bariatric surgery was cost-effective at 10 years and cost-saving over the lifetime of the Italian patient cohort considered in this analysis. © 2017 The Author(s) Published by S.

    Full Text Available Although the exact pathogenic processes involved in vitiligo are still unknown, its association with autoimmune disorders and endocrine dysfunction has been reported. One of its associations is with thyroid diseases. The purpose of this retrospective study was to determine the prevalence of thyroid function tests and thyroid autoantibody abnormalities in children diagnosed with vitiligo and compare the results with the literature. The laboratory documents of thyroid function tests (FT3, FT4, and TSH and thyroid autoantibodies (TgAb and TPOAb belonging to the pediatric vitiligo patients were studied retrospectively. Thyroid function tests and thyroid autoantibody abnormalities were detected in 20 (25.3% of the pediatric vitiligo patients. Thirteen (16.4% patients were evaluated as subclinical hypothyroidism, two (2.5% were evaluated as hypothyroidism, and five (6.3% were evaluated as euthyroidism. Thyroid autoantibodies were found to be positive in nine (11.3% patients. Previously reported prevalence of thyroid disease in children with vitiligo ranged from 10.7 to 24.1%, and the prevalence of 25.3% determined in this study was compatible with the literature. Also, the high rate of subclinical hypothyroidism determined in these patients attracted attention to the probable development of overt hypothyroidism in a long term. Thus, our results suggest that thyroid function tests and thyroid autoantibodies should be analyzed in children with vitiligo.

    A retrospective study. To report midterm clinical and radiographic results of Graf artificial ligament stabilization in the treatment of degenerative spondylolisthesis and to evaluate the role of this procedure and its surgical indications for surgical success. Nonfusion surgeries including artificial disc replacement and ligamentoplasty are increasingly gaining interest to avoid adverse effects of spinal fusion. Sixty-four consecutive patients with degenerative spondylolisthesis underwent artificial ligament stabilization. Surgical indication was symptomatic degenerative spondylolisthesis with adjacent segment pathologies (6.3%). One patient (1.6%) underwent consequent spinal arthrodesis at the ligamentoplasty level. Artificial ligament stabilization did not improve the vertebral slip but maintained lordosis and preserved segmental motion in 80% of patients. This procedure is an effective alternative to spinal arthrodesis in the treatment of symptomatic degenerative spondylolisthesis (Grade I) with minimal disc space narrowing and coronal facet tropism.

    Background: Survival rates after curative surgery for gastric cancer are disappointing. Therefore adjuvant therapeutic strategies are required. Aim: To analyze survival and side effects of treatment among gastric cancer patients treated with adjuvant chemoradiotherapy after curative resection of gastric adenocarcinoma. Material and methods: Retrospective review of medical records of 74 patients aged 20 to 74 years, treated with complete resection of gastric adenocarcinoma followed by adjuvant chemo radiation. Survival analysis was based on the records and information from the National Mortality Registry. Results: Five years survival fluctuated from 50% among patients in stage 1B to 25% among those is stage IV. Significant acute toxicity was observed in 23 patients (31%). No patients died due to acute toxicity. Eleven patients (16.4%) developed significant late toxicity, with two possible deaths related to treatment. Conclusions: Postoperative chemoradiotherapy is feasible in our experience. Continuos infusion of 5- fluoruracil is recommended to reduce toxicity

    It is known from several studies, including those from RERF that radiation exposure can cause thyroid tumors (Socolow, N Engl J Med. 1963;268:406, Parker, Ann Intern Med. 1974;80:600). Effects of radiation on autoimmune thyroid disease are not well understood. We have conducted thyroid disease screening on a population of 2856 individuals from the Adult Health Study (AHS) cohort of atomic-bomb survivors for the period of 1984-1987. This study, which for logistical reasons involved survivors only from Nagasaki, revealed a statistically significant relationship between radiation dose and prevalence of solid nodules, including cancer, and that of autoimmune hypothyroidism (Nagataki, JAMA. 1994;272:364). Because the previous thyroid study was conducted only in Nagasaki, the new comprehensive thyroid disease screening study has been ongoing in Hiroshima and Nagasaki AHS participants since March 2000. For about 4,000 participants in Hiroshima and Nagasaki AHS cohort, thyroid ultrasonography, aspiration biopsy of nodules, thyroid function test, thyroid autoantibody (thyroid peroxidase antibody and thyroglobulin antibody) test by highly sensitive assay using enzyme linked immunosorbent assay were performed for the diagnosis of thyroid diseases. Analysis of data from the 1874 people examined through July 2001 (915 people from Hiroshima, 959 people from Nagasaki) provides evidence that thyroid cancer increases with radiation dose. The prevalence of positive result for thyroid autoantibody test is increased in the people exposed to relative low dose of radiation (0.01-0.99 Sv). Examination and measurements was completed in February 2003 for all patients. The analysis of these data is providing new and more complete insights into relationships between thyroid diseases and low doses of radiation

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

    The TRAb content of the thyroid diseases 758 cases (including the first visit thyroidism group 166 cases; the thyroidism group with normal thyroid function by medicine treatment 198 cases, the group with abnormal thyroid function by medicine treatment 86 cases, the group with lower thyroid function 24 cases, the group with normal thyroid function by 131 I treatment 104 cases, the subacute thyroiditis group 48 cases, the simple goiter group 52 cases, the primary hypothyroidism group 80 cases) and the normal control group 62 cases are detected. The results show that the values of TRAb are much higher in the groups with normal or abnormal thyroid function by medicine treatment, the group with lower thyroid function, the group with 131 I treatment and the group with primary hypothyroidism than that of control group (P 0.05). The differential of the TRAb average and positive rate is obvious between the groups with normal and abnormal thyroid function by medicine treatment (P 131 I treatment (P < 0.01). The TRAb levels in serum are higher in the patients with thyroidism and primary hypo-thyroidism, and the TRAb levels are normal in the patients with subacute thyroiditis and simple goiter. So, TRAb is a auxiliary index in the diagnosis of thyroidism and hypo-thyroidism and also a differential diagnosis index about the thyroidism and subacute thyroiditis. At the same time, TRAb is an important index in evaluating the autoimmune monitoring function of the body, and stopping the use of thyroid medicine
