AIM
The primary aim of our study was to measure the effect of conventional open thyroidectomy performed for patients with multinodular goiter (MNG) on pulmonary volumes measured with respiratory function tests independent from surgical indications. A secondary aim was to determine whether there was a significant improvement in the complaints due to obstructive symptoms after MNG surgeries.
METHODS
This study was conducted between October 2020 and June 2022. Patients who were hospitalized to undergo surgery for giant multinodular goiter were prospectively included in the study. Patients were questioned about complaints of pressure, hoarseness, dyspnea, sleep apnea, snoring, and dysphagia before the surgery and during the follow-up 6 months after surgery. In addition, pulmonary function tests were performed preoperatively, 48 hours after surgery and 6 months after surgery. Forced expiratory volume in 0.5 seconds forced expiratory volume in 1 second and forced vital capacity values in pulmonary function test (PFT) measurements were recorded.
RESULTS
A total of 55 patients, 42 females and 13 males, mean age 49.54 ± 13.6 years, were included in the study. Although there was a significant decrease in clinical symptoms caused by the thyroid volume within 6 months in patients who were operated for giant MNG there was no significant change in pulmonary function tests. There was a positive correlation between the thyroid volume and nodule weight in patients with MNG.
CONCLUSIONS
Our results suggest that it is not necessary to follow up with patients without obstructive findings in preoperative pulmonary function tests with pulmonary function tests in the postoperative period.

BACKGROUND
Atrioventricular block (AVB) is rare in hyperthyroidism (HTH). Little is known about the true prevalence, clinical course, optimal management, and outcomes of different types of AVBs in patients with HTH. To address these uncertainties, we aimed to conduct a systematic review by combining the available literature to provide more meaningful data regarding AVBs in HTH.
METHODS
We systematically searched PubMed, Scopus, Embase, and Google Scholar for articles reporting patients who developed AVB in the context of HTH. Data were analysed in STATA 16. The main outcomes included types of AVB, frequency of pacemaker insertion, and resolution of AVB. The systematic review is registered with the International Prospective Register of Systematic Reviews (PROSPERO) with the identification number CRD42022335598.
RESULTS
A total of 56 studies (39 case reports, 12 case series, 3 conference abstracts, 1 retrospective study, and 1 prospective observational study) with 87 patients were included in the analysis, with a mean age of 39.1 ± 17.6 years. Females constituted 65.7% ( = 48) of the cohort. Complete heart block (CHB) was the most commonly reported AVB ( = 45, 51.7%), followed by first-degree AVB (16.1%) and second-degree AVB (14.9%). Overall, 21 patients underwent pacing. A permanent pacemaker was inserted in one patient with second-degree AVB and six patients with CHB. Mortality was reported in one patient with CHB. The clinical course and management of HTH and AVBs did not differ in patients with CHB or lower-degree blocks. Apart from lower rates of goitre and more use of carbimazole in those who underwent pacing, no differences were found when compared to the patients managed without pacing.
CONCLUSION
Current data suggest that CHB is the most common type of AVB in patients with HTH. Most patients can be managed with anti-thyroid management alone. Additionally, whether pacemaker insertion alters the clinical outcomes needs further exploration.

Hyperthyroidism is increased synthesis and secretion of thyroid hormones by the thyroid gland resulting in thyrotoxicosis. The modality of therapy for hyperthyroidism includes anti-thyroid drugs, radioiodine and surgery. Anti-thyroid drugs are the only available therapy for hyperthyroid patients in developing world as radioiodine is inaccessible and surgical set up does not exist as required. The aim of this study was to determine the magnitude and predictors of uncontrolled hyperthyroidism among hyperthyroid patients after prolonged anti-thyroid drug use. An institutional-based cross sectional study was conducted at the University of Gondar hospital, Northwest Ethiopia, between April 1, 2022 and October 31, 2022. A consecutive sampling method was used to recruit 317 study subjects. Data were collected through a pre-designed questionnaire. Patients were interviewed to obtain socio-demographic data and relevant medical information. Laboratory analyses were done based on the follow up protocol. Data were entered into EPI Info version 4.6.0.0 (EPI Info, Atlanta) and analyzed in STATA version 14 (Stata Corp LP, Texas, USA). Binary logistic regression model was used to identify variables associated with uncontrolled hyperthyroidism among hyperthyroid patients. P value < .05 was used to declare significant association. A total of 317 patients with hyperthyroidism were included in the study. The median age of the study subjects was 45 years (IQR 36-55 years). Most (95%) of the study participants were females. Toxic multi-nodular goiter was the most common cause of hyperthyroidism (92%), followed by toxic adenoma (5%) and Graves' disease (2%). On multivariate binary logistic regression, large goiter size (AOR: 3.163, 95% CI [1.333-7.506]), severe disease (AOR: 2.275, 95% CI [1.060-4.880]), infrequent iodinated salt intake (AOR: 3.668, 95% CI [1.245-10.802]), and poor adherence to anti-thyroid drug (AOR:15.724, 95% CI [5.542-44.610]) were statistically significant with uncontrolled hyperthyroidism at 12 months of anti-thyroid drug intake. A quarter of patients with hyperthyroidism didn't achieve euthyroid state after 12 months of anti-thyroid drug use. The identified predictors for non-euthyroid state were large goiter size, severe disease, infrequent iodinated salt intake, and poor adherence to anti-thyroid drug.

INTRODUCTION
Surgical campaigns for thyroid surgery in low-income environments are very efficient, but there is little literature reporting results. These campaigns are complex due to multiple particularities: highly evolved cases, the need for professionals to travel or an obvious socio-cultural barrier influence towards the surgical act. We describe a surgical campaign in Cameroon to treat patients with goiter and issue some medical and sociocultural recommendations in view of our experience for its implementation with guarantees.
MATERIAL AND METHODS
An experienced group carried out an 11-day campaign at the Saint Martin de Porres Dominican Hospital, Yaounde, Cameroon. Demographic data, TSH values, surgery and complications after a 12-month follow-up were analyzed.
RESULTS
Thirty-eight patients with goiter were selected for the campaign and 32 patients (mean age, 40-years-old; 30 females) were operated. Bilateral goiter, as assessed with echography, was diagnosed in 13 patients (41%). Ten patients (31%) had a WHO grade II goiter (visible with the neck in a normal position). The surgical procedures were 18 unilateral thyroidectomy with isthmectomie, 13 total thyroidectomy, and 1 totalizing thyroidectomy, due to previous unilateral thyroidectomy (cancer recurrence). A pathological study in 13 patients (40%, extra cost 60 €) showed benign multinodular goiter/thyroid nodule (12 patients) and an extensive papillary carcinoma (one patient). Six months postoperatively, 3 patients had a slight dysphonia and one patient had persistent hypocalcemia. Follow-up was completed in all patients, either face to face (75%, 24 patients) or by phone (25%, 8 patients who failed to have a TSH test because of its cost, 23 €).
CONCLUSIONS
Surgical campaigns to treat thyroid pathology can be carried out with guarantees if a series of important steps are followed: active participation of the patient's environment, thyroid ultrasound by the surgical team to decide which technique, intense awareness about monitoring and hormone replacement therapy, and the participation of local personnel for long-term follow-up.

BACKGROUND
Nonadherence to medications is a common clinical issue. We describe a case in which weekly visits to assess medication adherence achieved euthyroidism in a patient with persistent primary hypothyroidism and suspected nonadherence to levothyroxine. The patient, however, did not report nonadherence.
CASE PRESENTATION
A male aged 67 years with multinodular goiter underwent total thyroidectomy for abnormal thyroid nodule biopsy. Surgical pathology revealed papillary thyroid cancer with lymph node metastasis for which he received radioactive iodine treatment. His plasma thyrotropin (TSH) was noted to be 0.28 uIU/mL (reference range 0.35-4.00 uIU/mL) 7 months postsurgery while taking 224 mcg levothyroxine tablets daily. His plasma TSH remained elevated for about 5 years despite titrations of the levothyroxine dosage, counseling, and multiple follow-up visits. A home care nurse was involved in monitoring the patient taking levothyroxine daily and correctly but was unsuccessful. The patient and his son reported taking levothyroxine daily and correctly. The patient was asked to visit the primary care clinic every week for 6 weeks with all his medications. Repeat plasma TSH normalized to 1.01 uIU/mL. The suspected etiology of previously high plasma TSH was nonadherence to levothyroxine, which was discussed in detail with the patient. The patient verbalized understanding, was willing to follow recommendations and ended the weekly clinic visits. Repeat plasma TSH was again high and the patient claimed adherence, but weekly visits to primary care clinic were resumed, and life-threatening consequences of hypothyroidism were discussed with the patient and his son. After 9 weeks of visits, he was noted to have low plasma TSH (0.23 uIU/mL).
CONCLUSIONS
Weekly visits seem impractical but may help in cases of persistent hypothyroidism in which the patient admits to being or is suspected to be nonadherent to levothyroxine. Knowing their medication use will be checked at weekly clinic visits may motivate the patient to be adherent.

PURPOSE
Worldwide, incidence of thyroid malignancy is increasing. The purpose of this study was to evaluate the pattern and magnitude of nodule types.
METHODS
A cross-sectional retrospective study was performed at Saint Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia, among patients who underwent thyroidectomy from May 2018 to June 2022. Data were extracted using a structured format. Descriptive statistics were performed using SPSS version 26 software. Results were presented in terms of percentages and frequencies.
RESULTS
During a 4-year period, 1,476 patients had thyroidectomies and histopathologic information of 212 malignant cases was studied. Within multinodular goiter (MNG), thyroid cancer accounted for 69.8% (n = 148) of patients, whereas in solitary nodules, it accounted for 30.2%. From the total, 160 participants (75.5%) were female, and the female:male ratio was 3.1 (mean, 41.72; ± standard deviation [SD], 16.44) years, and age range of 12-88 years versus men, who have a mean of 44.71 (±SD, 14.91) years and an age range of 21-78 years. The mean age of male cases with solitary nodule and MNG was 40.6 and 46.5 years, respectively. The most frequent cancer in both types of nodules, accounting for 59% of patients, was papillary carcinoma, which was found in 64% of solitary nodules and 57.4% of multinodular nodules. Overall, 14.1% of tumors had multiple centers (17.4% in multinodular nodules and 6.9% in solitary nodules). In 7.1% of patients, microcarcinoma (<1 cm) was found, with papillary carcinoma accounting for 91.7% of the total.
CONCLUSION
Compared with men, women with cancer typically manifested at a younger age. Males with malignancy in solitary nodules had a lower mean age than those with MNGs. The most frequent and significant cause of multicentric presentation is papillary carcinoma.

BACKGROUND
Anaplastic thyroid carcinoma (ATC) is a highly aggressive malignancy that has consistently shown Wnt/β-catenin (canonical) signaling activation in various study populations. There are currently no targetable treatments for BRAF-wildtype ATC and a lack of effective treatment for BRAFATC. Our aim is to identify whether Wnt inhibitors could be potential therapeutic agents for ATC patients with limited treatment options.
METHODS
In this Institutional Review Board-approved study, we utilize a cohort of 32 ATCs and 20 non-neoplastic multinodular goiters (MNG). We also use 4 ATC spheroid cell lines (THJ-16T, THJ-21T, THJ-29T, and THJ-11T) and two primary patient-derived ATC organoid cultures (VWL-T5 and VWL-T60). Finally, we use a murine xenograft mouse model of ATC for in vivo treatment studies.
RESULTS
Using a large patient cohort, we demonstrate that this near-universal Wnt signaling activation is associated with ligand expression- rather than being mutationally-driven. We show that pyrvinium pamoate, a potent Wnt inhibitor, exhibits in vitro efficacy against both ATC cell lines and primary patient-derived ATC organoids VWL-T5 (p < 0.05) and VWL-T60 (p < 0.01) Finally, using a murine xenograft model of ATC, we show that pyrvinium significantly delays the growth of ATC tumors in THJ-16T (p < 0.005) and THJ-21T (p < 0.001).
CONCLUSIONS
We tested Wnt inhibitor treatment, both in vitro and in vivo, as a potential novel therapy for this highly lethal disease. Future large-scale studies utilizing multiple Wnt inhibitors will lay the foundation for the development of these novel therapies for patients with ATC.

Multinodular goiter (MNG) is a chronic benign nodular enlargement of the thyroid gland. It presents as an anterior painless neck mass, potentially progressing to exert pressure on the trachea and esophagus and giving rise to compressive symptoms. MNG is a common thyroid gland disorder; however, retropharyngeal goiter is considered rare with few reported cases. We report the cases of two patients who presented to our institution with MNG with retropharyngeal extension: a 62-year-old female patient who presented with a progressive anterior neck mass with dilated neck veins; and a 49-year-old male who presented with a painless anterior neck mass. Both patients successfully underwent total thyroidectomy with an uneventful postoperative recovery. The clinical presentation of MNG with retropharyngeal extension varies with patients; hence, a high index of suspicion is of the utmost significance. While the retropharyngeal extension does not cause compressive symptoms, it should raise the suspicion of a large retrosternal component.

Thyrotoxicosis, also known as hyperthyroidism, is a condition characterized by the excessive production of thyroid hormones by the thyroid gland. Besides Graves' disease, other common causes of thyrotoxicosis include toxic multinodular goiter, toxic adenoma, and subacute thyroiditis. The treatment of thyrotoxicosis depends on the underlying cause and may include medications (e.g., antithyroid drugs, beta-blockers), radioactive iodine therapy, or surgical removal of the thyroid gland (thyroidectomy). In this report, we present two instances of thyrotoxicosis where conventional high doses of antithyroid treatment failed to control the condition effectively. This failure prompted the exploration of alternative therapeutic interventions. These cases highlight the intricacies involved in managing thyrotoxic crises that do not respond to methimazole (MMI), emphasizing the necessity for innovative approaches such as plasmapheresis and thyroidectomy. Understanding such scenarios is vital for enhancing the care provided to patients encountering resistance to standard treatments. The distinct clinical pathways and treatment strategies adopted in these cases offer valuable insights into this disease management, particularly concerning resistance to MMI.

Review
DICER1 syndrome is a rare genetic disorder with the progressive development of malignant and non-malignant diseases in childhood. The cause of this syndrome is a dusfunction of the endoribonuclease DICER, which plays an important role in the processing of microRNAs with subsequent regulation of the control of the expression of oncogenes and tumor suppressor genes. Clinical manifestations of dyseropathies is very different and may include both endocrine manifestations - multinodular goiter, differentiated thyroid cancers, ovarian stromal tumors, pituitary blastoma, and non-endocrine formations - pleuropulmonary blastoma, cystic nephroma, pineoblastoma. The presence of somatic mutations of the DICER1 gene is a resultant stage in the pathogenesis of dyseropathies, determining the further path of oncogenesis. At present, DICER1 syndrome is diagnosed extremely rarely, which leads to late detection of the components of the disease in the patient, late diagnosis of neoplasms, lack of family counseling. Diagnosis at the early stages of the disease, the development of screening programs for the management of these patients allows minimizing the risks of developing more malignant, aggressive forms of the disease.
