The Effect of Laser Thermal Ablation on Quality of Life: Improvements in Patients with Solid-Cystic Thyroid Nodules.

Background: Evidence of the efficacy of laser thermal ablation (LTA) in benign thyroid nodules is abundant. However, little is known about the effect on quality of life (QoL) of this treatment. Methods: Prospective cohort study investigating the effect of LTA before, three, and six months after LTA on QoL using the thyroid-specific patient-reported outcome (ThyPRO) measure. Patients receiving LTA (laser group [LG]) was compared with a well-characterized control group (CG) from the Danish civil registry. Results: The LG comprised 54 patients, with no age or sex differences compared with the CG (n = 739). Sixty-nine percent of the patients had a recurrent cystic thyroid nodule, 6% had a solid nodule, while the remaining 25% were of mixed character. The median nodule volume was 6.8 mL (interquartile range [IQR]: 4.0-11.1) before LTA, and 1.8 mL (IQR: 0.6-4.1) at 6 months post-LTA (p < 0.001), corresponding to a median reduction of 78%. All cystic fluid (median: 6 mL; IQR: 2.0-9.0) was aspirated before LTA. Median treatment time was 400 seconds (IQR: 300-600), applying a median energy of 823 J (IQR: 600-1200). At baseline and according to the ThyPRO scales, the LG differed significantly from the CG by having more goiter symptoms, hyperthyroid symptoms, tiredness, and cognitive complaints (p < 0.05 for all variables), but only the difference in the goiter symptom scale was of a clinically important magnitude. At three months, the LG experienced a large improvement in goiter symptoms (effect size [ES] = 1.05), a moderate improvement in cosmetic complaints (ES = 0.50), and a moderate improvement in the overall QoL (ES = 0.64). Only the improvements in the goiter symptom and the cosmetic complaint scales were clinically important. Six months after LTA, the anxiety scale showed further improvement of moderate size (ES = 0.52). At 6 months, the results above were maintained, and 79% of patients experienced a large and clinically important improvement in the goiter symptom scale and no clinically important differences were found between the LG and the CG. Conclusions: In this unblinded, prospective observational study, measures of disease-specific QoL were significantly improved compared with preprocedure levels, in patients with solid-cystic nodules.

Impact of thyroidectomy on quality of life in benign goitres: results from a prospective cohort study.

PURPOSE: Benign thyroid diseases encompass a large spectrum of conditions that are chronic and subtle in nature. A majority of patients choose non-surgical management and continue living their daily lives with subconscious impairment of optimal functioning. We studied the effect of thyroidectomy on the quality of life (QoL) in patients with benign goitres. METHODS: A prospective study was conducted on 50 patients between January 2017 and August 2018 using the ThyPRO 39 questionnaire. This is a disease-specific health-related questionnaire administered the day before surgery and 6 months following surgery. Data analysis was performed using EpiData Manager and EpiData Entry Client (v 3.1). RESULTS: The mean age of the cohort was 43.30 years ± 11.61, with a female preponderance (34:16). The most common indications for surgery were suspicion of malignancy and compressive symptoms in 34% and 30%, respectively. The most common histopathology reported was nodular/adenomatous hyperplasia (56%). Prior to surgery, the most common domains affected were emotional susceptibility and tiredness. Following surgery, a significant improvement in all domains of the ThyPRO 39 questionnaire were seen except for psychological well-being (p=0.126). In addition, the composite scores significantly improved (p<0.001). Younger age, female gender, and longer duration of goitre were the factors that significantly affected the outcomes in various domains. CONCLUSION: Patients with benign goitres have subtle impairment of QoL which showed significant improvement following thyroidectomy.

How Should Thyroid-Related Quality of Life Be Assessed? Recalled Patient-Reported Outcomes Compared to Here-and-Now Measures.

BACKGROUND: The impact of thyroid disease on quality of life is an important disease aspect that is best investigated by patient-reported outcomes. Recent patient-reported outcomes research has raised concern about the validity of traditional retrospective questionnaires. Therefore, ecological momentary assessments of patients' subjective well-being have been introduced to avoid recall bias and improve contextual validity. Despite theoretical advantages, the measurement properties remain unsubstantiated. This study examines the relationship between the retrospective thyroid-related quality of life patient-reported outcome measure (ThyPRO) and a momentary (here-and-now) version of ThyPRO. METHODS: Eighty-three newly diagnosed hyperthyroid patients expected to undergo treatment completed questions on their thyroid-related quality of life. Head-to-head comparison was performed between 12 momentary items from four multi-item ThyPRO scales administered three times daily via a smartphone application during 28 days and the original retrospective ThyPRO on day 28. The measurement difference between recalled and momentary ratings was quantified for all four scales. Furthermore, correlations between the measures were investigated, and their agreement was explored using Bland-Altman plots. Finally, the study examined whether retrospective ratings were influenced by two forms of recall bias (the peak effect and the end effect). RESULTS: Retrospective and mean momentary ThyPRO ratings were highly correlated (Pearson's correlations: 0.74-0.88). However, retrospective ratings provided significantly higher scores (i.e., worse quality of life) on all scales. Bland-Altman plots showed a skewed distribution, indicating low levels of agreement. Results supported a peak effect for retrospective ratings on tiredness but not for the remaining scales. Further, results supported end effects for retrospective ratings of emotional susceptibility and anxiety. CONCLUSIONS: Retrospective and mean momentary ThyPRO ratings correlated strongly, but retrospective ratings were higher, indicating more disease impact. The differences were of magnitudes normally deemed clinically relevant. Limited evidence supported peak and end effect bias for retrospective assessments. The two measurement modalities did not appear congruent and thus cannot be used interchangeably. When designing clinical studies, whether to use a momentary or retrospective measurement method may depend on the aim of measurement. Further prospective analyses are needed to compare any beneficial effects, for example in terms of higher precision or sensitivity to clinical change, of momentary assessments.

Globus Symptoms in Patients Undergoing Thyroidectomy: Relationships with Psychogenic Factors, Thyroid Disease, and Surgical Procedure.

BACKGROUND: The number of patients who need thyroid surgery has increased worldwide in recent decades. Patients with thyroid disease experience globus pharyngeus as a result of direct compression and edema of the surrounding organs. Thyroid surgery is needed to improve these symptoms or as treatment for thyroid cancer. After thyroid surgery, globus symptoms may become worse and may affect the daily life of the patient for a long time. Psychogenic problems have also been thought to cause the globus sensation. A prospective analysis of globus symptoms and psychogenic factors following thyroidectomy was performed. MATERIAL AND METHODS: Patients scheduled to undergo thyroid surgery between February and September 2016 completed the foreign-body sensation in the throat score (FBST; range 0-8.2) and the self-rating depression scale (SDS; range 0-100) preoperatively and three days, one month, three months, six months, and 12 months postoperatively. RESULTS: Long-term follow-up was completed in 616 patients (491 females). A total of 365 patients had thyroid cancer, 169 had benign tumors, and 82 had diffuse goiters with Graves' disease. The percentage of patients who complained about neck discomfort (FBST >2) was 29.4% before surgery. A preoperative high FBST showed a significant direct correlation with a high SDS, but thyroid volume did not. A postoperative high FBST was seen in 75.3% of patients at two days and 78.9% at one month after surgery, and it then gradually decreased to 49.3% at 12 months after surgery. At three days after the operation, the median FBST was significantly higher in patients who had total thyroidectomy with lateral neck dissection or total thyroidectomy only compared to those who had lobectomy only (p < 0.05). These differences were still present 12 months after surgery. A higher preoperative SDS score was also identified as an independent predictor for a high FBST at 12 months after surgery, but not at one or three months postoperatively, on multivariate analyses. CONCLUSION: Preoperative globus symptoms appear directly related to psychological factors. The area of the surgical procedure and preoperative psychological factors were related to persistent neck discomfort.

Phonatory symptoms and impact on quality of life in female patients with goiter.

Our objective is to report on the prevalence of phonatory symptoms and impact on quality of life in a group of female patients with goiter who had not been selected for surgery or who had not presented to the emergency room with respiratory distress. A total of 40 patients with goiter and 14 controls were enrolled in this study. Demographic data included age, sex, laryngopharyngeal reflux disease, allergy, smoking, duration of disease, presence or absence of compressive symptoms, presence or absence of thyroid gland nodules, vascular status, presence or absence of calcifications, and thyroid-stimulating hormone levels. Phonatory symptoms included hoarseness, vocal fatigue, vocal straining, lump sensation, and aphonia. The Voice Handicap Index 10 was used to assess the impact of phonatory symptoms on quality of life. The most common phonatory symptom in the patients with goiter was vocal fatigue followed by lump sensation. The only phonatory symptom that was significantly more present in patients with goiter was vocal straining. As for the impact of phonatory symptoms on quality of life, 15.8% of goiter patients had a Voice Handicap Index score >7 compared with 7.7% of controls. Phonatory symptoms are common in patients with goiter, with vocal straining occurring significantly more frequently than in controls. In 1 of 6 patients, the presence of phonatory symptoms had an impact on quality of life.

Quality of life improvement in patients with Hashimoto thyroiditis and other goiters after surgery: A prospective cohort study.

INTRODUCTION: Hashimoto thyroiditis (HT) and other benign goiters (BG) might influence patients' quality of life (QoL). The objective of this study was to analyze influence of surgery on these patients' QoL. METHODS: A prospective cohort study was conducted. The ThyPRO questionnaire was used in the QoL assessment. RESULTS: The HT patients experienced significantly worse hypothyroid symptoms and sex life than the BG patients. The improvement in QoL in the BG patients was significant after surgery in all ThyPRO domains. In the HT patients, the improvement was significant in all but two domains, eye symptoms and cognitive impairment. The best improvement in both groups was in overall QoL. None of the patients developed permanent consequences. CONCLUSIONS: The QoL of HT and BG patients is impaired and improves significantly after surgical treatment. Thyroidectomy should be considered as a treatment option in the HT patients more often as in the BG patients.

Quality of life in patients with benign nontoxic goiter: impact of disease and treatment response, and comparison with the general population.

BACKGROUND: While health-related quality of life (HRQoL) issues often prompt treatment of benign nontoxic goiter (NTG), few clinical studies have systematically assessed HRQoL in patients with this condition. The purpose of the present study was to evaluate thyroid-related and generic HRQoL in patients with benign NTG, as compared to the general population, before and six months after treatment. METHODS: Thyroid-related and generic HRQoL were assessed with Thyroid Patient-Reported Outcome (ThyPRO) and Medical Outcomes Study 36-item Short Form (SF-36), respectively. Baseline and six-month post-treatment HRQoL assessments were obtained from 111 patients with NTG who underwent radioiodine therapy (32%), hemithyroidectomy (53%), total thyroidectomy (12%), or cyst aspiration with ethanol sclerotherapy (4%). Euthyroid patients were enrolled at baseline, 80% of whom remained euthyroid six months post-treatment, with 20% experiencing subclinical thyroid dysfunction. Normative ThyPRO (n=739) and SF-36 (n=6638) data were collected from representative general population samples. Score differences between patients and the general population were analyzed with multivariate linear regression analysis, adjusting for age, sex, comorbidity, and educational status. Changes in scores between baseline and follow-up were analyzed with the paired t-test, and magnitudes of score changes were evaluated as effect sizes (mean difference/SDbaseline; 0.2-0.5 indicating small, 0.5-0.8 moderate, and >0.8 large effects). RESULTS: Patients' baseline scores were significantly worse than those in the general population on 9 of the 13 ThyPRO scales. Six months after treatment, the patients' ThyPRO scores had improved on six scales, with large/moderate effects on the Goiter Symptoms and Anxiety scales. However, on eight scales, the post-treatment patient scores were still significantly worse than the general population scores. At baseline, patients had worse scores than the general population on four of the eight SF-36 scales and the SF-36 Mental Component Summary, none of which improved after treatment. CONCLUSIONS: Compared with the general population, patients with NTG had greatest HRQoL impairment at baseline on the Goiter Symptoms and Anxiety scales, which also demonstrated the largest post-treatment improvements. However, both disease-specific and generic HRQoL deficits persisted six months after treatment. In order to improve individualized care, future studies should focus on identifying risk factors for persistent HRQoL deficits and compare HRQoL effects of the various goiter treatment modalities in relation to thyroid phenotype.

Assessing health-related quality of life in patients with benign non-toxic goitre.

Health-related quality of life (HRQoL) assessments are increasingly used to evaluate treatment effects and to shape the delivery of value based care. Valid generic and disease specific tools are available for quantifying HRQoL in patients with non-toxic goitre. However, few studies have applied these validated instruments to assess HRQoL in patients with benign non-toxic goitre. Limited evidence suggests that patients with non-toxic goitre have HRQoL impairments in multiple HRQoL domains. While the HRQoL-impact of non-toxic goitre may be small relative to other severely disabling medical conditions, treatment is almost exclusively elected for HRQoL indications. Thus better quantification of HRQoL, particularly at better (or more favorable) levels where many patients score, is essential. Web and mobile technologies have eased the ability to deliver surveys to patients. Routine consideration of HRQoL provides the opportunity to monitor the impact of treatment on the outcomes most meaningful for patients and the opportunity to help shape the delivery of value based health care.

The thyroid-related quality of life measure ThyPRO has good responsiveness and ability to detect relevant treatment effects.

BACKGROUND AND PURPOSE: Patient-reported outcomes have become important endpoints in comparative effectiveness research and in patient-centered health care. Valid patient-reported outcome measures detect and respond to clinically relevant changes. The purpose of this study was to evaluate responsiveness of the thyroid-related quality of life (QoL) instrument ThyPRO in patients undergoing relevant clinical treatments for benign thyroid diseases and to compare it with responsiveness of the generic SF-36 Health Survey. METHODS: A sample of 435 patients undergoing treatment completed the ThyPRO and SF-36 Health Survey (Version 2) at baseline and 6 months after treatment initiation. Responsiveness was evaluated in three thyroid patient groups: patients with hyperthyroidism (n = 66) and hypothyroidism (n = 84) rendered euthyroid after medical therapy, and patients with a clinically detectable nontoxic goiter treated with surgery or radioactive iodine and remaining euthyroid (n = 62). Changes in QoL were evaluated in terms of effect size and compared to the changes predicted by clinical experts. The responsiveness of equivalent scales from ThyPRO and SF-36 Health Survey were compared with the relative validity index. RESULTS: The ThyPRO demonstrated good responsiveness across the whole range of QoL aspects in patients with hyper- and hypothyroidism. Responsiveness to treatment of nontoxic goiter was also demonstrated for physical and mental symptoms and overall QoL, but not for impact on social life or cosmetic complaints, in contrast to clinicians' predictions. For all comparable scales except one, the ThyPRO was more responsive to treatment than the SF-36 Health Survey. CONCLUSIONS: The ThyPRO was responsive to treatment across the range of benign thyroid diseases. We suggest implementing this measurement instrument as a patient-reported outcome in clinical studies and in clinical management.

Improvement of quality of life in patients with benign goiter after surgical treatment.

PURPOSE: A quality of life (QoL) assessment is considered an important outcome measure in the treatment of benign thyroid diseases. The aims of this study were to analyze the impact of different surgical treatments on QoL in patients with benign thyroid diseases and to evaluate factors correlating with the QoL outcomes. METHODS: A prospective longitudinal study was conducted. One hundred thirty-two patients met the inclusion/exclusion criteria and completed the disease-specific questionnaire, thyroid patient-reported outcome (ThyPRO), before surgery and after 6 months. Preoperative and postoperative QoL outcomes were compared and correlating factors were analyzed. RESULTS: Indication for surgery was euthyroid goiter, toxic goiter, and suspicious malignant thyroid disease in 58.3, 29.5, and 12.1 % of the patients, respectively. None of the patients had overtly toxic goiter. There were 65.2 % of the patients who underwent total thyroidectomy, while 34.8 % underwent hemithyroidectomy. The total postoperative complication rate was 5.3 %. QoL improved significantly after surgical treatment, independent of the extent of performed surgery. The most affected domain, pre- and postoperative, was for tiredness. QoL improvement was significant for women in all domains, while for men, it was significant in only three domains (goiter symptoms, emotional susceptibility, and cosmetic complaints) and in overall QoL. Younger patients had significantly better cognitive functioning and daily life, while elderly patients had significantly less cosmetic complaints. The factors that significantly correlated with improvement of QoL in different domains were lower education level, duration of disease, and microcarcinoma at final histology. CONCLUSION: QoL in patients with benign thyroid diseases improves significantly after operative treatment, independent of the extent of the operation.

What is the real significance and management of major thyroid disorders in bipolar patients?

Thyroid disfunction affects negatively emotional stability and worsens the clinical course of bipolar affective disorder. The main stabilizer used in this illness, lithium carbonate has numerous effects on the physiology of the thyroid, with the most significant being the inhibition of thyroid hormone release that may occur at therapeutic levels. These dysfunctions have also been reported most frequently in bipolar patients not undergoing treatment with lithium, and was not completely explained by the effects of this drug. Apart from the numerous medical complications and mood disturbances, the cognitive or perceptual system may also be affected. In fact, the presence of thyroid disease increases the rates of obsessive compulsive disorder, phobias, panic disorder, major depressive disorder, cyclothymia, or bipolar disorder. In severe cases of hypothyroidism, the clinical symptoms and signs can be similar to a melancholic depression or dementia. It is therefore important to know well all these possible complications in daily clinical practice. This review will cover the main thyroid dysfunctions present in bipolar patients, whether ot not produced by treatment with lithium carbonate, and will provide a series of recommendations for clinical management.

Quality of life (QoL) in patients with benign thyroid goiters (pre- and post-thyroidectomy): a prospective study.

BACKGROUND: Preservation of quality of life (QoL) seems an important therapeutic goal in patients with benign thyroid diseases. The aim of the present study was to investigate the impact of thyroidectomy on QoL in patients with benign goiters and to assess the significance of various factors affecting the outcome. METHODS: A prospective study consisting of 100 patients with benign goiters was conducted between November 2009 and March 2011. Patients completed a disease-specific ThyPRO questionnaire to assess QoL before and 6 months after thyroidectomy. Preoperative and postoperative scores were compared; and univariate and multivariate analyses were performed. RESULTS: Mean age of the patients was 40.5 years (M:F = 1:4.3); 82 % of the patients had nodular goiters, and the remaining 18 % had diffuse disease. None of the patients had overt thyroid dysfunction at the time they completed the questionnaire. Operative treatment for 54 % of the patients involved total thyroidectomy, whereas 46 % underwent hemithyroidectomy. None of these patients developed any permanent morbidity following surgery. Mean scores of QoL in the 12 domains examined were low and improved significantly (p < 0.001) after surgery: symptoms, 19.4 versus 0.7; fatigue, 29.5 versus 1.5; vitality, 44.4 versus 3.0; memory and concentration, 25.7 versus 1.5; nervousness, 29.6 versus 1.8; psychological well-being, 33.9 versus 1.3; mood swings, 34.9 versus 0.8; relationship, 15.4 versus 1.4; daily activity, 18.7 versus 1.3; sex life, 20.9 versus 1.7; appearance, 14.7 versus 1.0; and overall, 27 versus 5.5. On univariate analysis, weight of goiter was found to be significantly associated with improvement in the scores of the memory and concentration domain (p = 0.03). On multivariate analysis, factors significantly associated with improvement in different domains were young age (nervousness, p = 0.009), female gender (fatigue, p = 0.02), and weight of goiter (symptoms, p = <0.001; vitality, p = <0.001; and memory and concentration, p = <0.001). CONCLUSIONS: Patients with benign goiters experience significant improvement in QoL after thyroidectomy.

Quality of life is not influenced by the extent of surgery in patients with benign goiter.

INTRODUCTION: The surgical approach to benign goiter is becoming increasingly radical due to the risk of recurrent goiter. The aim of this prospective study was to evaluate the impact of surgery on health-related quality of life (HRQoL) of patients with benign goiter. MATERIAL AND METHODS: HRQoL data from 115 patients with benign goiter were analyzed. Thirty-three patients (group 1) had a hemithyroidectomy. Sixty-five patients (group 2) had a so-called Dunhill operation (hemithyroidectomy + near-total thyroidectomy of the opposite side), and in 17 patients, a total resection of the goiter was performed. The validated HRQoL instrument, the EuroQol-5D, was applied to measure the health-related quality of life. RESULTS: With an overall complication rate of 10% and no permanent recurrent laryngeal nerve palsy, it was shown that surgery for benign goiter is safe. In the validated HRQoL questionnaire (EQ-5D), no significant variance could be found between different surgical procedures such as thyroidectomy, hemithyroidectomy, or Dunhill procedure. Further, no significant differences in QoL were found in EQ-5D questionnaire compared to normal population. CONCLUSION: Thyroid surgery can be done safely and without impairment of life quality, regardless of the extent of the operation.

[Measurement of health-related quality of life in thyroid patients]. / Måling af helbredsrelateret livskvalitet hos patienter med thyroideasygdomme.

Few studies describing the health-related quality of life (HRQL) in thyroid patients have been published and a validated thyroid-specific HRQL measure is lacking. Studies indicate reduced HRQL in thyroid patients, but the studies are small or methodologically weak. Many clinically-relevant questions about HRQL and thyroid disease remain unanswered and the current sparse results are contradictory. This may be due to the lack of a valid HRQL measurement. Hopefully, increased focus on HRQL and the development of a valid thyroid-specific HRQL measure will improve this status.

Investigation of intelligence quotient and psychomotor development in schoolchildren in areas with different degrees of iodine deficiency.

This investigation aims to observe the intelligence and psychomotor development of the schoolchildren in iodine deficiency (ID) areas after the adoption of Universal Salt Iodization (USI), and evaluate the effect of the adoption of USI on their intelligence and psychomotor development. 564 schoolchildren (306 males and 258 females, age range from 8 to 13 yrs) from areas with severe, moderate, and mild ID were investigated. Intelligence quotient (IQ) was measured by Combined Raven's test, second edition. Psychomotor development was examined by Jinyi Psychomotor Test Battery (JPB). We found that the IQ scores of all subjects in the severe and moderate ID areas were 102 +/- 15.6 and 99.5 +/-16.6 respectively, lower than those in the mild ID areas (108 +/- 12.4, p < 0.01). The IQ scores correlated negatively with age (partial r = -0.17; beta = -1.95; p < 0.0001). The total T scores of JPB of all subjects in the severe and moderate ID areas were 316 +/- 42.3 and 330 +/- 47.7 respectively, lower than those in the mild ID areas (342 +/- 48.1, p < 0.05). The total T scores of JPB correlated negatively with age (partial r = -0.15; beta = -4.94; p = 0.0006). We may conclude that after the adoption of USI in the ID areas investigated, USI has probably made a contribution to the partial recovery of intelligence and psychomotor development injured by ID in schoolchildren, and should be strengthened.

Which domains of thyroid-related quality of life are most relevant? Patients and clinicians provide complementary perspectives.

OBJECTIVE: To identify how thyroid diseases impact the patients' lives and to select the most relevant quality of life (QoL) issues for a thyroid-specific questionnaire. DESIGN: Fifteen thyroid experts and 80 thyroid outpatients (14 with nontoxic goiter, 12 nodular toxic goiter, 21 Graves' disease, 17 thyroid-associated ophthalmopathy, and 16 primary hypothyroidism) were interviewed. METHODS: The relevance of 138 thyroid disease-related issues was rated during interviews. For each issue, three relevance measures were obtained: a diagnosis-specific patient rating, a diagnosis-specific expert rating, and a combined overall patient/expert rating. The 75 most relevant issues overall and the 15 most relevant issues in each patient category were selected. RESULTS: Based on the above, 92 issues were selected, covering a broad range of clinical and QoL domains. Across patient groups, broader QoL domains were most relevant, especially fatigue and emotional susceptibility. However, when focusing on individual patient groups, diagnosis-related physical symptoms were very relevant too. Patients rated issues about psychosocial problems and impact on daily life as more relevant, whereas clinicians focused on thyroid-characteristic issues. CONCLUSIONS: A broad range of QoL issues and physical symptoms are relevant for thyroid patients, particularly fatigue and emotional susceptibility. Patients and clinicians offer complementary perspectives on relevance.

Thyroidectomy does not cause globus pattern symptoms.

Post-thyroidectomy patients often complain of globus pharyngeus type symptoms. One of the organic pathologies recognized as causing globus pattern symptoms is goitre. We conducted a prospective questionnaire-based study in the thyroid clinic at Hull Royal Infirmary to examine the relationship between goitre, thyroidectomy and globus pattern symptoms by using the Glasgow-Edinburgh Throat Scale. A questionnaire-based study in which 41 consecutive patients due to undergo thyroidectomy prospectively completed the questionnaire pre-operatively and 12 months post-operatively. A subset of 25 randomly selected patients also completed the questionnaire three months post-operatively. Globus symptoms were not worsened by thyroidectomy at three or 12 months. Indeed two of the questioned parameters were significantly improved at three months, and six at one year (p < 0.023). In conclusion, thyroidectomy does not exacerbate globus pharyngeus symptoms. Indeed, in the absence of other clinical causes, when a patient has a World Health Organization (WHO) 2 goitre or greater, thyroidectomy may improve them.

Increased risk of affective disorder following hospitalisation with hyperthyroidism - a register-based study.

OBJECTIVE: The pattern of comorbidity between thyroid disorders and affective disorder is not fully known. We assessed whether hospitalisation with hyperthyroidism was a risk factor for hospitalisation with affective disorder and evaluated the temporal relationship between these events. DESIGN: A historical prospective cohort study comparing patients with hyperthyroidism with patients with non-toxic goitre or osteoarthritis, using existing data from Danish registers. The observational period was from 1 January 1977 to 31 December 1999. METHODS: Three study cohorts were identified by their International Classification of Diseases (ICD) diagnoses at discharge from hospital and consisted of all patients with a first hospital admission with the index diagnoses of hyperthyroidism, osteoarthritis, or non-toxic goitre. Later admissions to psychiatric hospital wards with discharge ICD diagnoses of affective disorder were used as events of interest. Rates of re-admission were estimated using competing risks models in survival analyses. Age, sex, substance abuse, and calendar time were included as co-variables. RESULTS: A study sample of 183 647 patients discharged with an index diagnosis was identified. In total 1374 events occurred in the observational period. An index diagnosis of hyperthyroidism was associated with an increased risk of hospitalisation with affective disorder for both sexes and for all age-bands investigated, compared with the other index diagnoses. The risk was greatest in the first six months after index hospitalisation (rate ratio, 95% confidence interval: 3.60 (2.58-5.04)). CONCLUSIONS: Patients hospitalised with hyperthyroidism are at greater risk of re-admission with depressive disorder or bipolar disorder than control patients. This suggests that hyperthyroidism is associated with long-term mood disturbances.

[Effect of preoperative preoperative visualization therapy on postoperative outcome after inguinal hernia surgery and thyroid resection]. / Einfluss einer präoperativen Visualisierungstherapie auf die postoperativen Ergebnisse nach Leistenherniotomie und Strumaresektion.

UNLABELLED: This randomized controlled trial aims to evaluate the influence of preoperative relaxation techniques on postoperative outcomes. From January 1997 to June 1998 208 patients were operated on for primary inguinal hernia or goiter. The patients were randomized into two groups: Group A (n = 103) underwent the surgical treatment with a preoperative visualization therapy. Group B (n = 105) underwent the surgical treatment without a preoperative therapy. Patients with age under 18 years, ASA-status IV-V, recurrent inguinal hernia or recurrent goiter and malignant neoplasms were excluded from the study. There were no differences in age, sex, duration of the operation, training of the surgeon, and preoperative blood parameters between the two groups. RESULTS: During the postoperative follow-up we observed more hematomas (group A with visualization therapy: 30.3%, group B without visualization therapy: 44.4%) as well as more pain (group A: 4.2, group B: 5.2) and analgesic consumption (group A: 59.7 mg Tramadol HCL, group B: 72.5 mg Tramadol HCL) in group B (p < 0.05). There were no significant differences in infections, nausea, hypocalcemia, tetania, recurrent nerve palsy, fever. CONCLUSIONS: Preoperative visualization therapy reduces significantly the number of postoperative hematomas after inguinal hernia repair. Furthermore a decrease of analgesic requirements after surgical treatment was observed.

[Mental status of patients with iodine-deficiency goiter]. / Osobennosti psikhicheskogo statusa u bol'nykh iododefitsitnym zobom.

Personality and intellectual characteristics were examined in 76 patients with iodine-deficiency goiter (IDG). Subclinical hypothyroidism forming as early as IDG of the 1st degree impairs abstractive and integral thinking, psychological maladaptation to the disease, high anxiety, neurotism, diminished intellectual performance, deterioration of memory, attention, predominance of thinking of concrete-action type. To prevent intellectual disturbances, IDG patients should receive replacement therapy with adequate doses of thyroid hormones preparations.
