Knowledge regarding stable iodine prophylaxis among populations affected by the Fukushima nuclear accident remains poorly characterized. We assessed knowledge levels and preferred information sources among parents of thyroid examination participants aged ≤18 years.

We conducted a cross-sectional descriptive study (April 2019 and December 2022) among parents of thyroid examination participants. Knowledge was assessed using 3 items: role recognition, distribution method awareness, and effectiveness duration (score 0-3). Preferred information providers for future emergencies were collected.

Among 1,116 participants (mean child age 12.3 years, 8.1-11.8 years post-disaster), the mean knowledge score was 1.66/3 (SD = 0.97). Only 22.1% showed high knowledge (score = 3), while 42.1% had low knowledge (score 0-1). Although two-thirds (67.8%) correctly recognized stable iodine’s role, distribution method awareness was most limited: 54.3% lacked awareness of how stable iodine is distributed. Regarding effectiveness duration, 51.2% correctly answered. Health professionals were largely preferred as information providers (90.5%).

Substantial knowledge gaps existed regarding stable iodine prophylaxis, particularly distribution methods. Health professionals, as the most trusted information source, may play a key role in addressing these gaps by communicating preparedness information to communities.

To appraise clinical practice guidelines for anaplastic thyroid carcinoma treatment and management using the Appraisal of Guidelines for Research and Evaluation II tool.

A literature search was performed using MEDLINE/PubMed, Embase, Scopus, Cochrane, and Google Scholar. Four reviewers evaluated clinical practice guidelines utilising Appraisal of Guidelines for Research and Evaluation II, with domain scores requiring a threshold of greater than 60 per cent. Inter-reviewer agreement was evaluated using intraclass correlation coefficients.

Twelve clinical practice guidelines were evaluated after application of inclusion and exclusion criteria. There were two “high-”, four “average-”, and six “low-” quality clinical practice guidelines. The domains with the highest scores were “clarity of presentation” (69.44 ± 16.75) and “scope and purpose” (68.87 ± 20.88), while “applicability” (7.12 ± 6.17) and “rigor of development” (50.26 ± 20.77) had the lowest scores. Intraclass correlation coefficients showed a high level of inter-reviewer agreement (0.689–0.924; good–excellent).

These results showcased wide variability in quality amongst guidelines for the treatment and management of anaplastic thyroid carcinoma. These findings necessitate greater standardisation among clinical practice guidelines and greater focus on the applicability of recommended practices.

This study analyses the incidence of subjectively experienced dysphagia and voice change in post-thyroidectomy and parathyroidectomy patients without recurrent laryngeal nerve palsy.

A total of 400 patients were invited to participate in a telephone questionnaire based on the Dysphagia Handicap Index and Voice Handicap Index. At 6–24 months following surgery, participants were divided into: post-thyroid surgery (total, hemi-, parathyroidectomy) groups and controls (other ENT procedures). A total of 254 responses were received (127 following thyroid surgery, 127 controls).

Twenty-two per cent of post-thyroidectomy patients had a Voice Handicap Index score of more than 3, compared to 15 per cent of parathyroid patients and 4 per cent of controls. The mean Dysphagia Handicap Index score for patients post thyroidectomy and hemi-thyroidectomy was 2.0. Parathyroidectomy patients had a mean Dysphagia Handicap Index score of 1.3, higher than controls at 1.0.

Dysphagia and voice alteration are common following thyroid surgery, even in the absence of recurrent laryngeal nerve injury. Both deficits occur more frequently following thyroid surgery than parathyroid surgery.

The 2014 British Thyroid Association guidelines acknowledged the value of risk-stratifying thyroid nodules by utilising an ultrasound reporting system (‘U’ classification). This study assessed whether using pre-existing parameters in combination can better stratify patients’ malignancy and completion thyroidectomy risks.

A multicentre, retrospective, observational review identified 936 NHS Greater Glasgow and Clyde patients from pathology records who underwent hemithyroidectomy between 1 January 2014 and 31 December 2019.

A total of 308 patients had thyroid malignancy, 180 (58.4 per cent) progressed to completion thyroidectomy. A nodule classified as ‘U3’ (indeterminate) was associated with a 35.4 per cent chance of malignancy and a 21.6 per cent risk of requiring completion surgery. Amalgamation of ‘U’ score with Thy score enhanced risk prediction. The malignancy rate in U3, Thy-3f nodules was 38 per cent, and 21 per cent required completion surgery. The malignancy and completion thyroidectomy rates were comparatively lower for U3, Thy-3a nodules (22 per cent and 14.3 per cent, respectively).

Combining ultrasound ‘U’ score and Thy score improves pre-operative thyroid nodule risk stratification, leading to better informed patients regarding the risks of malignancy and completion surgery. A move towards an integrated assessment approach should be considered.

Guidance for the management of thyroid nodules has evolved over time, from initial evaluation based predominantly on clinical grounds to now including the established role of ultrasound and fine needle aspiration cytology in their assessment. There is, however, significant variation in the management of thyroid nodules depending on which national guidelines are followed. In addition, there are certain clinical situations such as pregnancy and paediatric thyroid nodules that have differing evaluation priorities.

This review aimed to provide an overview of currently accepted practices for the initial investigation and subsequent management of patients with thyroid nodules for the non-specialist. The review also addresses areas of variance between the systems in common clinical use, as well as newer, evolving technologies, including molecular testing in the evaluation of malignancy in thyroid nodules.

We present the case of a patient who after a year of psychotic symptoms is diagnosed with thyroid cancer with hyperthyroidism.

A brief review is made of the psychotic symptoms in a patient with hyperthyroidism secondary to cancer of the gland.

We present the case of a 52-year-old patient, a former injecting drug addict, who after a year with psychotic symptoms, is diagnosed with thyroid cancer with hyperthyroidism. The patient reported that a year ago, he suddenly had a painless and indurated lump in his neck, associated with weight loss and confusional symptoms. One month after the appearance of the tumor, the patient began to present visual, kinesthetic and haptic hallucinations, with the sensation that supernatural beings were passing through and possessing him. Likewise, he referred to being able to see and feel the atoms of matter, being able to communicate with a superior being whom he called “creator”.

The patient is admitted for psychotic symptoms. During it, the necessary complementary tests are carried out, objectifying a clinical situation of hyperthyroidism. The study is extended, observing a hyperfunctioning nodule, which corresponded to thyroid cancer.

Neuropsychiatric symptoms in hyperthyroidism are relatively common. In most cases, the most frequent are cognitive alterations, attention problems and working memory problems. It can also lead to depressive episodes, and more rarely, psychotic symptoms.

No significant relationships.

The incidence of thyroid carcinoma has been increasing worldwide and surgery is the primary treatment. Central compartment dissection of the neck is a very delicate procedure given the risks of recurrent laryngeal nerve injury and hypoparathyroidism.

This paper gives a detailed description of this surgical technique in a patient affected by papillary carcinoma of the thyroid gland, supported by highly representative iconographic materials from a tertiary department.

A stepwise description is provided, along with high-quality pictures and specific tips and tricks. Although neck dissection is a well-codified procedure, the fine details of this surgical technique are not currently available and are still the prerogative of the expert surgeon.

The central neck compartment contains several vulnerable structures; damage to these structures would affect patients’ lives, possibly permanently. Anatomical knowledge and standardisation are needed for all surgeons, particularly new surgeons (such as residents) who cannot rely simply on experience.

To evaluate the circumstances in which recurrent laryngeal nerve palsy occurs after thyroid surgery.

This study assessed 1026 patients who underwent surgery for benign thyroid disease over a seven-year period in a retrospective, single-centre study.

With a total of 1835 recurrent laryngeal nerves at risk, there were 38 cases (2.07 per cent) of transient recurrent laryngeal nerve palsy and 8 (0.44 per cent) of permanent recurrent laryngeal nerve palsy. No explanation was found for 10 of the 46 cases of recurrent laryngeal nerve palsy. Among the 38 other cases, the probable causes included poor identification of the recurrent laryngeal nerve during surgery, involuntary resection of the nerve and several other factors.

Apart from accidental resection of the recurrent laryngeal nerve during thyroid surgery, the causes of post-operative recurrent laryngeal nerve palsy are often unclear and likely multifactorial. Poor identification of the recurrent laryngeal nerve during surgery is still the main cause of post-operative recurrent laryngeal nerve palsy, even when intra-operative neuromonitoring is used.

Radiation exposure to the thyroid gland during breast irradiation can lead to hypothyroidism and this can impact on the quality of life. The aim of this study was to analyse if there is any difference in the radiation dose received by the thyroid gland during supraclavicular irradiation for breast cancer, with two different neck positions—straight or when the head is turned to the contralateral side to the breast being treated, when using a conformal technique.

All patients who received chest wall/breast and supraclavicular irradiation for breast cancer in 2019 in our department were divided into two groups based on the neck position as SN (neck positioned straight) and TN (neck tilted to contralateral side). The volume of thyroid gland, the radiation dose and volume parameters for Dmax, Dmean, and V5 to V40 of the thyroid were tabulated.

There were 72 patients included in the study with a mean age of 59 years, with 39 in the SN group and 33 in the TN group. There was no significant difference in thyroid volume between the two groups. Dmean, V15, V20, V25, V30 and V35 were significantly lower in tilted neck patients as compared to straight neck patients.

Neck positioned to the contralateral side of the breast primary may be recommended for conformal CT-based radiation planning.

This study aimed to report the pre- and post-operative laryngeal endoscopic findings in patients referred by non-otolaryngologists who are undergoing thyroid and/or parathyroid surgery, and to determine the number and nature of referrals before and after the release of the clinical practice guideline for improving voice outcomes after thyroid surgery.

This retrospective cohort study, conducted at a tertiary care academic hospital, comprised adult patients referred by the endocrine surgery service for laryngoscopy from 2007 to 2018 (n = 166). Data regarding patient demographics, reason for referral and endoscopic findings were recorded.

The number of referrals increased significantly after the release of the practice guideline. The most common indication for referral pre- and post-operatively was voice change. The most common finding during laryngoscopy was normal examination findings (pre-operatively) and unilateral vocal fold immobility (post-operatively).

Peri-operative thyroid and/or parathyroid patients have laryngoscopic findings other than vocal fold immobility. Laryngoscopy to detect structural and functional pathology is warranted.
