ABSTRACT

BACKGROUND: Lugol solution is often administered to patients with Graves' disease before surgery. The aim is to reduce thyroid vascularization and surgical morbidity, but its real effectiveness remains controversial. The present study was designed to evaluate the effects of preoperative Lugol solution on thyroid vascularization and surgical morbidity in patients with Graves' disease undergoing total thyroidectomy. METHODS: Fifty-six patients undergoing total thyroidectomy for Graves' disease were randomly assigned to receive 7 days of Lugol treatment (Lugol+ group, 29) or no Lugol treatment (LS- group, 27) before surgery in this single-centre and single-blinded trial. Preoperative hormone and colour Doppler ultrasonographic data for assessing thyroid vascularization were collected 8 days before surgery (T0) and on the day of surgery (T1). The primary outcome was intraoperative and postoperative blood loss. Secondary outcomes included duration of surgery, thyroid function, morbidity, vascularization, and microvessel density at final pathology. RESULTS: No differences in demographic, preoperative hormone or ultrasonographic data were found between LS+ and LS- groups at T0. At T1, free tri-iodothyronine (FT3) and free thyroxine (FT4) levels were significantly reduced compared with T0 values in the LS+ group, whereas no such variation was observed in the LS- group. No differences between T0 and T1 were found for ultrasonographic vascularization in either group, nor did the histological findings differ. There were no significant differences between the LS+ and LS- groups concerning intraoperative/postoperative blood loss (median 80.5 versus 94 ml respectively), duration of surgery (75 min in both groups) or postoperative morbidity. CONCLUSION: Lugol solution significantly reduces FT3 and FT4 levels in patients undergoing surgery for Graves' disease, but does not decrease intraoperative/postoperative blood loss, thyroid vascularization, duration of surgery or postoperative morbidity. REGISTRATION NUMBER: NCT05784792 (https://www.clinicaltrials.gov).

ABSTRACT

PURPOSE: This study aimed to investigate the relationship between Lugol iodine treatment in a rescue setting and surgical outcomes in Graves' disease patients. METHODS: The retrospective register-based cohort study included 813 patients who had undergone primary total thyroidectomy with a primary diagnosis of Graves' disease (ICD-code E05.0) at Karolinska University Hospital in Stockholm, Sweden, between January 2008 and December 2015. Of 813 patients, 33 (4.1%) were given Lugol iodine before surgery and the remaining, the non-Lugol group, did not. The study's primary outcomes were post-operative calcium treatment day 1, calcium and vitamin D supplements at discharge and follow-up. Secondary outcomes were laryngeal nerve damage and bleeding (defined as re-operation). RESULTS: Differences were found between the Lugol and non-Lugol groups in the treatment of calcium day 1 (45.5% vs 26.7%, p = 0.018), at discharge (36.4% vs. 16.2%, p = 0.002) and vitamin D supplements at discharge (36.4% vs. 19.1%, p = 0.015) as surrogate variables for hypocalcemia post-operatively. No differences could be seen at 4-6 weeks and six-months follow-up. There were no differences between the Lugol and non-Lugol groups in terms of operation time, laryngeal nerve damage, and bleeding. CONCLUSION: Patients in our cohort undergoing thyroidectomy due to Graves' disease pre-operatively treated with Lugol iodine as a rescue therapy had a higher risk of experiencing short term post-operative hypocalcemia.

ABSTRACT

OBJECTIVES: Iodide transport defect (ITD) is one of the principal causes of congenital hypothyroidism (CH) and its primary molecular mechanism is a mutation of the sodium/iodide symporter (NIS) gene. This study aims to analyse the clinical characteristics and genetic mutations of ITD. METHODS: The participants were a pair of siblings diagnosed with congenital hypothyroidism. Inductively coupled plasma mass spectrometry was used to determine the concentration of salivary iodine and serum iodine and to calculate their ratio. At the same time, next-generation sequencing (NGS) was applied to detect all exons of congenital hypothyroidism-related genes. All suspicious variants were further validated in the patients and their parents by PCR and Sanger sequencing. RESULTS: Both patients were conclusively diagnosed with thyroid iodine transport defect (ITD). NGS identified two variants of the NIS gene in the siblings: c.1021G>A (p.Gly341Arg) with paternal origin and c.1330-2A>C with maternal origin. Both of these variants have not been reported to date. They are predicted to be pathogenic based on these clinical symptoms and comprehensive software analysis. CONCLUSIONS: This is the first reported family study of congenital hypothyroidism with SLC5A5 mutation in China. Next-generation sequencing technology is an effective means of studying the genetics of congenital hypothyroidism. The therapeutic effect of potassium iodide needs to be further evaluated.

ABSTRACT

BACKGROUND AND AIMS: Lugol's iodine chromoendoscopy is an important method to detect esophageal squamous cell carcinoma. Sodium thiosulfate solution (STS) has been used to neutralize iodine after Lugol's chromoendoscopy; however, it is not available in many medical centers. The aim of the current study was to assess the efficacy of N-acetylcysteine solution (NAC) for relieving symptoms caused by Lugol's iodine chromoendoscopy. METHODS: Patients were randomized to receive either STS or NAC after spraying Lugol's iodine solution on the esophagus. The neutralizing effects for residual iodine in the esophagus and gastric mucous pool were observed. The primary endpoint was the intensity of retrosternal pain and/or heartburn measured by a visual analog scale (VAS) score 30 minutes after chromoendoscopy. Secondary endpoints were the rate of patients with any adverse symptom, rate of moderate to severe retrosternal discomfort occurring, and heart rate variability between time points before and after chromoendoscopy. RESULTS: The neutralization rates for residual iodine between the NAC and STS groups were not significantly different (P > .999). The difference of median VAS scores between the NAC and STS groups 30 minutes after chromoendoscopy was .0 (P = .719; 95% confidence interval, .0-.0), and the 95% confidence interval higher limit was .0, which was less than our prespecified margin of .5, concluding an noninferiority of NAC with regard to STS. There was no significant difference between the 2 groups regarding the rate of patients with any adverse symptom, rate of moderate to severe retrosternal discomfort, or heart rate variability at 5 minutes or 30 minutes after chromoendoscopy. CONCLUSION: As a very easily accessible reagent in clinical circumstances, NAC can also alleviate mucosal irritation symptoms induced by Lugol's chromoendoscopy at similar efficacy as STS and can be routinely recommended.

ABSTRACT

OBJECTIVES: Thyroid storm (TS) is a rare but life-threatening condition caused by decompensated hyperthyroidism. There is no consensus on how to diagnose pediatric TS. We report three pediatric cases of TS presenting with central nervous system (CNS) and gastrointestinal (GI) symptoms as the initial presentation of Graves' disease. CASE PRESENTATION: They were previously healthy adolescents without family history of thyroid disease. CNS symptoms varied from agitation to coma. GI symptoms included abdominal pain, vomiting, and diarrhea. Their laboratory studies revealed thyrotoxicosis and positive result of thyroid-stimulating antibody (TSAb). They were admitted to the intensive care unit (ICU) and received the combination of an antithyroid drug, Lugol's solution, a beta antagonist, and hydrocortisone. The most severe case was a 13 year-old Japanese girl who presented with loss of consciousness and hemodynamic shock. She died after 5 days of intensive treatment. CONCLUSIONS: Pediatricians should consider TS in the differential diagnosis when a patient exhibits both CNS and GI symptoms.

ABSTRACT

AIM: To assess the effectiveness of the use of the antiviral drug enisamium iodide in the complex treatment of acute respiratory viral infections (ARVI) caused by various pathogens in routine clinical practice. MATERIALS AND METHODS: А prospective randomized study included 134 patients who were treated in the epidemic season of influenza and ARVI in 20182019. All patients were examined for the presence of influenza A and B viruses, respiratory syncytial virus, human metapneumovirus, parainfluenza virus, coronaviruses, rhinoviruses, adenoviruses in nasopharyngeal swabs by PCR. Patients of the main group received enisamium iodide along with symptomatic therapy, the control group received only symptomatic therapy. The primary parameter of the effectiveness of therapy was evaluated on the scale of the general severity of the manifestations of ARVI (Total Symptom Score TSS) from the 2nd to the 4th day and by the secondary criteria of effectiveness: assessment of the duration of ARVI, the severity of fever, the proportion of patients with normal body temperature, the duration of the main clinical symptoms of acute respiratory viral infections, the proportion of patients in whom complications requiring antibiotics were noted, the dynamics of interferon status on the 6th day. To conduct a statistical analysis, depending on the efficiency parameter, the ANCOVA method with a fixed group factor and an initial score on the TSS severity scale was used as covariates, a criterion for comparing quantitative indicators in two independent groups. RESULTS: According to the results of the analysis of the primary efficacy parameter, the median (interquartile range) of the average score on the scale of the general severity of ARVI manifestations in the main group was 4.33 (3.675.83), in the comparison group 6.00 (4.677.25; p0.001). The duration of systemic and local manifestations of acute respiratory viral infections was statistically significantly less in the main group (p=0.002 and p=0.019, respectively). Prescription of additional therapy was required in 2 (2.9%) patients of the main group (patients taking enisamium iodide), compared with 8 (11.9%) patients in the control group. Serum levels of interferon  and interferon  on the last day of treatment were statistically significantly higher in patients of the main group compared with the control group (p0.001). Treatment (excellent) was evaluated by 42 (62.7%) patients, while in the control group only 17 (25.8%) patients gave similar ratings. Both patients (p0.001) and doctors (p0.002) rated therapy tolerance better in the study group. CONCLUSION: The results confirmed the safety and effectiveness of enisamium iodide as a treatment for ARVI and influenza. The antiviral, interferonogenic and anti-inflammatory properties of the drug are involved in the formation of an antiviral response and reduce the risk of complications, which makes it possible to reduce the number of symptomatic agents used.

ABSTRACT

Although simple febrile seizures are relatively common and benign in toddlers, it is important to rule out any underlying critical disease that necessitates further intervention and treatment. Thyroid storm, the extreme manifestation of hyperthyroidism, is relatively rare and not often considered in the differential diagnosis of a febrile seizure despite its high mortality rate. Here, we report 1 of the youngest patients with thyroid storm, who initially presented with a febrile seizure. After reevaluation, the 2-year-9-month-old patient was discovered to have thyromegaly, which led to recognition that her persistent tachycardia and widened pulse pressure were likely signs of thyrotoxicosis. Laboratory results were consistent with primary hyperthyroidism due to Graves' disease. Thyroid storm was then diagnosed on the basis of clinical features including gastrointestinal and central nervous system disturbances. Treatment with methimazole, propranolol, hydrocortisone, and Lugol's iodine solution was used. This medication regimen was safe and effective with restoration of a euthyroid state after 2 months and no recurrence of seizures. Improved awareness of hyperthyroidism and thyroid storm can lead to prompt diagnosis and treatment of this endocrine emergency, thus reducing mortality and morbidity. Pediatricians should consider this diagnosis in children with febrile seizures and suggestive vital signs and physical examination findings.

ABSTRACT

Influenza and ARVI represent the most numerous and dangerous group of causative agents of respiratory infections human. AIM: Characterization of the antiviral properties of enisamium iodide against human respiratory viruses in in vitro experiments. MATERIALS AND METHODS: In the course of experiments, the cytotoxic properties of enisamium iodide were studied against the cell lines Vero, MA-104, A549, L-41 and HEp-2. The antiviral activity of enisamium iodide was studied using virus yield reduction assay against influenza viruses, parainfluenza virus, respiratory syncytial virus, Coxsackie B3 and Coxsackie B4 viruses, as well as adenoviruses types 5 and 6. RESULTS: The most sensitive to the action of enisamium iodide was the human parainfluenza virus, whose activity decreased by 2.3 orders of magnitude under the action of the drug in A549 cells. Of the cell cultures used, enisamium iodide exhibited the maximum antiviral effect in human lung carcinoma cells A549, where, in its presence, the level of reproduction of adenoviruses of types 5 and 6, Coxsackie viruses B3 and B4, and human parainfluenza virus decreased by an order of magnitude or more. The antiviral activity of enisamium iodide was least manifested in Vero cells. CONCLUSION: According to the results of in vitro experiments, enisamium iodide can be considered as an antiviral drug with a wide spectrum of activity against human respiratory viruses.

ABSTRACT

A 48-year-old woman was admitted to our hospital because of headache and fever. She was diagnosed with aseptic meningitis. Five days later, she had a seizure and developed left hemiparesis. Magnetic resonance imaging showed hyperintensity in the right parietal area on fluid attenuated inversion recovery imaging. She was diagnosed as having cerebral venous thrombosis (CVT) because the suprasagittal sinus was invisible on the venographic studies. Moreover, deep venous thrombosis (DVT) was detected in her left lower extremity. Laboratory findings showed hyperthyroidism and markedly increased factor VIII activity. This is a rare case of concomitant CVT and DVT induced by high factor VIII activity due to hyperthyroidism under the presence of meningitis, an additional risk factor for thrombosis.

ABSTRACT

The incidence of anal squamous cell carcinoma (ASCC) in the U.S. is increasing, particularly in immunocompromised patients. Preventative screening is used to monitor precancerous dysplasia known as anal intraepithelial neoplasia (AIN), which can progress to ASCC. High Resolution Anoscopy (HRA) is one screening procedure that uses a colposcope with acetic acid and Lugol's iodine solution to visualize the anal epithelium for AIN. HRA has offered potential in managing AIN, but as more evidence emerges it is unclear whether HRA provides definitive benefit. This narrative review updates readers on the efficacy of HRA in screening AIN, compares HRA to other techniques, compares the use of HRA in various high-risk populations, and offers practical information on the use of HRA. Keyword searches were conducted using MEDLINE, Web of Science, and Cochrane Library. Current literature is mixed regarding the utility of HRA. Further randomized controlled trials are needed to definitively assess the role of HRA.

ABSTRACT

Hyperthyroidism is a common metabolic disorder, although its presentation as an endocrine emergency called thyroid storm is rare. Here we review a case of a thyroid storm as the initial presentation of thyrotoxicosis, with multiple organ failure and haemodynamic collapse due to low-output cardiac dysfunction. Quick intervention with aggressive antithyroid therapy, including steroid pulse, and supportive intensive care measures led to an outstanding improvement and full recovery. The present case clearly shows the beneficial impact of initial clinical suspicion resulting in an early diagnosis and intensive therapy. Moreover, it supports the additional role of steroids to aggressive antithyroid strategy in order to control associated deleterious systemic inflammatory reactions.

ABSTRACT

Thyrotoxicosis and diabetic ketoacidosis (DKA) both may present as endocrine emergencies and may have devastating consequences if not diagnosed and managed promptly and effectively. The combination of diabetes mellitus (DM) with thyrotoxicosis is well known, and one condition usually precedes the other. Furthermore, thyrotoxicosis is complicated by some degree of cardiomyopathy in at least 5% de patients; but the coexistence of DKA, thyroxin (T4) toxicosis, and acute cardiomyopathy is extremely rare. We describe a case of a man, previously diagnosed with DM but with no past history of thyroid disease, who presented with shock and severe DKA that did not improve despite optimal therapy. The patient evolved with acute pulmonary edema, elevated troponin levels, severe left ventricular systolic dysfunction, and clinical and laboratory evidence of thyroxin (T4) toxicosis and thyrotoxic cardiomyopathy. Subsequently, the patient evolved favorably with general support and appropriate therapy for DKA and thyrotoxicosis (hydrocortisone, methimazole, Lugol's solution) and was discharged a few days later.

ABSTRACT

PURPOSE: This study aimed to compare the accuracy of Papanicolaou test cytology, visual inspection with 5% acetic acid (VIA), and visual inspection with Lugol iodine (VILI) in the detection of premalignant and malignant lesions of the cervix. MATERIALS AND METHODS: This was a cross-sectional comparative study of 200 consenting participants at the Federal Teaching Hospital, Abakaliki over a 6-month period. All the participants had Papanicolaou test cytology. Subsequently, they were classified into two groups of 100 each through systematic random sampling: group 1 had VIA and group 2 had VILI. Thereafter, all the participants had cervical punch biopsy at the 6 and 12 o'clock cervical positions. Cervical punch biopsy was also done on the suspicious lesions of the cervix irrespective of their positions. The tests of validity of the three methods were calculated using the histology of the biopsy specimen as the gold standard. P value ≤ .05 was considered to be statistically significant. RESULTS: Among the VIA group, 19 (19%) had cervical epithelial abnormalities on Papanicolaou test cytology, and VIA was positive in 14 (14%). Histology results showed cervical neoplasia in 15 (15%) of the participants. Among the VILI group, 15 (15%) had cervical epithelial abnormalities on Papanicolaou test cytology, and VILI was positive in 19 (19%). Histology results showed cervical neoplasia in 15 (15%) of the participants. There was no significant difference in overall accuracy of Papanicolaou test cytology, VIA, and VILI. The overall accuracy of the Papanicolaou test cytology plus VIA was significantly more than Papanicolaou test cytology alone. CONCLUSION: VIA or VILI can be used as a stand-alone cervical cancer screening test when compared with Papanicolaou test cytology, particularly in resource-limited settings. VIA can also complement Papanicolaou test cytology.

ABSTRACT

BACKGROUND: The tyrosine kinase Src is involved in the progression of many cancers. Moreover, inhibiting Src activity has been shown to obstruct several signaling pathways regulated by the EGFR. Thus, Src is a valuable target molecule in drug development. The purpose of this study was to identify compounds that directly or indirectly modulate Src to suppress lung cancer cell growth and motility and to investigate the molecular mechanisms underlying the effects of these compounds. METHODS: Human non-small cell lung cancer (NSCLC) cell lines (PC9, PC9/gef, A549, and H1975) with different EGFR statuses were tested by cytotoxicity and proliferation assays after AC-93253 iodide treatment. Src and Src-related protein expression in AC-93253 iodide-treated PC9, PC9/gef, and A549 cells were assessed by western blotting. The effects of AC-93253 iodide on cancer cell colony formation, invasion, and migration were assessed in PC9 and PC9/gef cells. The synergistic effects of gefitinib and AC-93253 iodide were evaluated by combination index (CI)-isobologram analysis in gefitinib-resistant cell lines. The efficacy of AC-93253 iodide in vivo was determined using nude mice treated with either the compound or the vehicle. RESULTS: Among the compounds, AC-93253 iodide exhibited the most potent dose-independent inhibitory effects on the activity of Src as well as on that of the Src-related proteins EGFR, STAT3, and FAK. Furthermore, AC-93253 iodide significantly suppressed cancer cell proliferation, colony formation, invasion, and migration in vitro and tumor growth in vivo. AC-93253 iodide sensitized tumor cells to gefitinib treatment regardless of whether the cells were gefitinib-sensitive (PC9) or resistant (H1975 and PC9/gef), indicating that it may exert synergistic effects when used in combination with established therapeutic agents. Our findings also suggested that the inhibitory effects of AC-93253 iodide on lung cancer progression may be attributable to its ability to modulate multiple proteins, including Src, PI3K, JNK, Paxillin, p130cas, MEK, ERK, and EGFR. CONCLUSIONS: Our data suggest that AC-93253 iodide inhibits NSCLC cell growth and motility by regulating multiple Src-related pathways. Our findings may facilitate the development of therapeutic strategies and anti-tumor drugs that may be useful for treating lung cancer in the future.

ABSTRACT

Lugol's solution and other preparations containing iodide have for almost a century been used as an adjuvant treatment in patients with Graves' disease planned for thyroidectomy. Iodide has been shown to decrease thyroid hormone levels and reduce blood flow within the thyroid gland. An escape phenomenon has been feared as the iodide effect has been claimed to only be temporary. Lugol's solution has many additional effects and is used in other settings beside the thyroid. Still, there are questions of its mode of action, which doses should be deployed, if it should be used preoperative in all thyroidectomies or only in a few selected ones if at all, what is its use in other forms of thyrotoxicosis besides Graves' disease, and what is the mechanism acting on the vasculature and if these effects are confined only to arterial vessels supporting the thyroid or not. This review aims to collate current available data about Lugol's solution and other iodide preparations in the management of Graves' disease and give some suggestions where more research is needed.

ABSTRACT

BACKGROUND: Visual inspection with acetic acid (VIA) and Lugol's iodine (VILI) are used to screen women for cervical cancer in low-resource settings. Little is known about correlates of their diagnostic accuracy by healthcare provider. We examined determinants of VIA and VILI screening accuracy by examiner in a cross-sectional screening study of 1528 women aged 30 years or older in a suburb of Kinshasa, Democratic Republic of Congo. METHODS: We used a logistic regression model for sensitivity and specificity to estimate the diagnostic accuracy of VIA and VILI, independently performed by nurse and physician, as a function of sociodemographic and reproductive health characteristics. RESULTS: Nurses rated tests as positive more often than physicians (36.3% vs 30.2% for VIA, 26.2% vs 25.2% for VILI). Women's age was the most important determinant of performance. It was inversely associated with sensitivity (nurse's VIA: p<0.001, nurse's VILI: p = 0.018, physician's VIA: p = 0.005, physician's VILI: p = 0.006) but positively associated with specificity (all four combinations: p<0.001). Increasing parity adversely affected sensitivity and specificity, but the effects on sensitivity were significant for nurses only. The screening performance of physician's assessment was significantly better than the nurse's (difference in sensitivity: VIA = 13%, VILI = 16%; difference in specificity: VIA = 6%, VILI = 1%). CONCLUSIONS: Age and parity influence the performance of visual tests for cervical cancer screening. Proper training of local healthcare providers in the conduct of these tests should take into account these factors for improved performance of VIA and VILI in detecting cervical precancerous lesions among women in limited-resource settings.

ABSTRACT

The NIH Office of Dietary Supplements (ODS) convened 3 workshops on iodine nutrition in 2014, each held in Rockville, Maryland. These workshops were part of the ongoing ODS Iodine Initiative, begun in 2011 in response to concerns that US pregnant women may be at risk of iodine deficiency and that a high fraction of prenatal dietary supplements do not contain the recommended amounts of iodine. The primary purpose of the workshops was to consider the data and resources necessary to evaluate the clinical and public health benefits and risks of maternal iodine supplementation in the United States. The first workshop focused on the assessment of iodine intake, the second focused on the assessment of iodine status, and the third focused on the design and interpretation of clinical trials of maternal iodine supplementation. Here we provide the background of the ODS Iodine Initiative, summarize the 3 workshops held in 2014, and introduce the articles that arose from the workshops and are published in this supplement issue.

ABSTRACT

AIM: Find out the condition of mucosal microflora in gastroduodenal ulcer patients in different phases of its recurrence, to determine changes in the value of dysbiotic changes in ulcerogenesis, develop and confirm new transendoscopic treatment of gastroduodenal ulcers. MATERIALS AND METHODS: The study included 134 patients and 10 healthy volunteers RESULTS: At relapse of peptic ulcer and distant from the ulcer areas of the mucosa were allocated to 28 genera and species of microorganisms with a wide range of enzymatic activity and cytotoxicity, that corresponds to the 2-3 degree dysbacteriosis and shows microbiological parameters infected wound which required sanation. CONCLUSION: Application for transendoscopic sanation of gastroduodenal ulcers of new compounds iodine-lysozyme, dimexide-iodine-lysozyme and chitosan with bactericidal and sorption effects, can significantly reduce the time of ulcer healing and restore normobiocenosis of mucosal microflora of the gastroduodenal zone.

ABSTRACT

PRINCIPLES: Preoperative management of hyperthyroid patients with Graves' disease who are unable to tolerate thionamides or have poor adherence to therapy is a challenging clinical problem. The goal of our study was to demonstrate the clinical efficacy of a rapid preoperative thyroid hormone blocking protocol and to assess specific surgical and treatment-related complications. METHODS: Ten patients with thyrotoxicosis due to Graves' disease were treated with a rapid thyroid hormone blocking protocol of Lugol's solution, dexamethasone and a beta-blocker. Two patients continued to receive antithyroid therapy with carbimazole. Adrenal function was assessed 4-6 weeks postoperatively with a low dose (1 µg) adrenocorticotrophic hormone-stimulation test. RESULTS: Before treatment, all patients had severe hyperthyroidism. Baseline median and interquartile range (IQR) of fT4 was 68.9 (45.7-92.1) pmol/l, and baseline median fT3 and IQR, 30 (19.1-40.9) pmol/l. After 10 days of treatment, the levels of free hormones were significantly reduced with fT4 concentrations slightly elevated (fT4, 26.7 [17-36.4] pmol/l, p <0.001 compared with corresponding pretreatment values), and the fT3 concentration was normal in 8/10 patients (fT3, 6.1 [4.6-7.6] pmol/l, p <0.001 compared with corresponding pretreatment values). All patients were clinically euthyroid with a heart rate of <80/min. Drug tolerability was excellent, and there were no side effects or exacerbation of hyperthyroidism. The peri- and postoperative course was uneventful in all cases. Adrenal function was normal in 7 out of 10 patients 4-6 weeks postoperatively. Three patients showed prolonged secondary adrenal insufficiency with normalisation of adrenal function after 3 to 6 months. CONCLUSION: Rapid and effective preoperative preparation of patients with Graves' disease is achievable with Lugol's solution, dexamethasone and a beta-blocker. The risk of temporary hypothalamic-pituitary-adrenal axis suppression has to be taken into account.
