In children, hypothyroidism usually presents non-specific symptoms; symptoms can emerge gradually, compromising a timely diagnosis. We report the case of a 13-year-old male, who was admitted to the hospital due to swelling of the torso and neck. Besides these symptoms, the child was healthy, except for a significant growth delay. Ultrasound evaluation and blood tests led to the diagnosis of myxedema secondary to severe hypothyroidism, which was due to autoimmune thyroiditis. Further investigations revealed pericardial effusion and pituitary hyperplasia, with hyper-prolactinemia. Treatment with levothyroxine led to edema regression and clinical, hemato-chemical and radiological improvement. After 6 months, growth velocity increased, although the recovery of growth already lost was not guaranteed. Brain MRI showed regression of pituitary hyperplasia. The diagnostic delay in this case was probably due to the patient's apparent good health, and the underestimation of growth restriction. This report underlines the importance of growth monitoring in adolescence, a critical period for identifying endocrine conditions; if undiagnosed, these conditions can lead to serious complications, such as myxedema in hypothyroidism, with potential effects beyond growth on multiple organs.

Review
In 15-20% of cases, Graves' disease (GD) shifts to Hashimoto's thyroiditis (HT), while the shift from HT to GD is rare. We present a case of a patient in whom HT shifted to GD, along with a literature review. A 50-year-old woman with myxedema was diagnosed with Hashimoto's disease due to hypothyroidism and the presence of antibodies against thyroid peroxidase (TPOAb) and thyroglobulin (TgAb); she also had thyroid stimulating antibodies (TSAb) without any signs of GD. Although thyroid hormone replacement therapy improved her thyroid function, 2 months later, hyperthyroidism appeared and did not improve after discontinuation of the replacement therapy. The patient was diagnosed with GD, which improved with antithyroid agent administration. To date, only 50 cases regarding conversion from HT to GD have been reported. The median age is 44 years (range, 23-82 years), and the median time of conversion is 7 years (range, 0.1-27 years). The male-to-female ratio of HT conversion to GD is 1:9, closer to that of regular GD (1:10) than that of general HT (1:18). All patients received thyroid hormone replacement therapy for hypothyroidism due to HT. Continuous evaluation of TSAb levels is recommended in HT, particularly in cases of TSAb-positive and those under replacement, since it may help predict conversion to GD. Evaluating the clinical characteristics of patients with HT preceding GD is crucial to ensure appropriate treatment and reduce the risk of adverse events.

Graves' disease (GD) is an autoimmune thyroid disease, which is considered the most common cause of primary hyperthyroidism. GD usually manifests with symptoms such as tremors, palpitations, heat intolerance, weight loss, and specific signs on physical examination (proptosis and pretibial myxedema). However, systemic involvement is also recognized, for example, hepatic involvement in patients with GD may range from asymptomatic laboratory findings of liver function derangement (either transaminases elevations or intrahepatic cholestasis) up to hepatic failure. We describe a rare case of Graves' thyrotoxicosis presenting with severe cholestasis and non-parathyroid hormone-related hypercalcemia. An extensive evaluation for hepatobiliary causes of cholestasis, including hepatic biopsy, was entirely negative. The patient was successfully treated with methimazole with subsequent clinical and biochemical improvement.

BACKGROUND
Myxedema coma is an extremely rare but fatal endocrine emergency that requires urgent recognition and treatment. We describe a case of severe hypothermia that rapidly deteriorated to cardiac arrest that was attributed to myxedema coma.
CASE PRESENTATION
A 52-year-old man without a history of hypothyroidism was transferred to our emergency department due to coma and profound hypothermia. The patient developed cardiac arrest immediately after hospital arrival but return of spontaneous circulation was achieved shortly after resuscitation. The patient was noted to have generalized, nonpitting edema, dry skin, severe respiratory acidosis, hyponatremia, and elevated creatinine kinase, which was indicative of hypothyroidism. Myxedema coma was confirmed by a thyroid profile. The patient was successfully treated with intravenous levothyroxine and glucocorticoid.
CONCLUSION
Although myxedema coma is a rare cause of severe hypothermia, emergency physicians should be familiar with its clinical features and management.

BACKGROUND
Severe hypothyroidism (SH) is a rare but life-threatening endocrine emergency. Only a few data are available on its management and outcomes of the most severe forms requiring ICU admission. We aimed to describe the clinical manifestations, management, and in-ICU and 6-month survival rates of these patients.
METHODS
We conducted a retrospective, multicenter study over 18 years in 32 French ICUs. The local medical records of patients from each participating ICU were screened using the International Classification of Disease 10th revision. Inclusion criteria were the presence of biological hypothyroidism associated with at least one cardinal sign among alteration of consciousness, hypothermia and circulatory failure, and at least one SH-related organ failure.
RESULTS
Eighty-two patients were included in the study. Thyroiditis and thyroidectomy represented the main SH etiologies (29% and 19%, respectively), while hypothyroidism was unknown in 44 patients (54%) before ICU admission. The most frequent SH triggers were levothyroxine discontinuation (28%), sepsis (15%), and amiodarone-related hypothyroidism (11%). Clinical presentations included hypothermia (66%), hemodynamic failure (57%), and coma (52%). In-ICU and 6-month mortality rates were 26% and 39%, respectively. Multivariable analyses retained age > 70 years [odds ratio OR 6.01 (1.75-24.1)] Sequential Organ-Failure Assessment score cardiovascular component ≥ 2 [OR 11.1 (2.47-84.2)] and ventilation component ≥ 2 [OR 4.52 (1.27-18.6)] as being independently associated with in-ICU mortality.
CONCLUSIONS
SH is a rare life-threatening emergency with various clinical presentations. Hemodynamic and respiratory failures are strongly associated with worse outcomes. The very high mortality prompts early diagnosis and rapid levothyroxine administration with close cardiac and hemodynamic monitoring.

Journal of the European Academy of... Jul 2023Primary cutaneous mucinoses (PCM) are rare diseases characterized by dermal or follicular mucin deposits.
BACKGROUND
Primary cutaneous mucinoses (PCM) are rare diseases characterized by dermal or follicular mucin deposits.
OBJECTIVES
A retrospective study characterizing PCM to compare dermal with follicular mucin to identify its potential origin on a single-cell level.
MATERIAL AND METHODS
Patients diagnosed with PCM between 2010 and 2020 at our department were included in this study. Biopsy specimens were stained using conventional mucin stains (Alcian blue, PAS) and MUC1 immunohistochemical staining. Multiplex fluorescence staining (MFS) was used to investigate which cells were associated with MUC1 expression in select cases.
RESULTS
Thirty-one patients with PCM were included, 14 with follicular mucinosis (FM), 8 with reticular erythematous mucinosis, 2 with scleredema, 6 with pretibial myxedema and one patient with lichen myxedematosus. In all 31 specimens, mucin stained positive for Alcian blue and negative for PAS. In FM, mucin deposition was exclusively found in hair follicles and sebaceous glands. None of the other entities showed mucin deposits in follicular epithelial structures. Using MFS, all cases showed CD4+ and CD8+ T cells, tissue histiocytes, fibroblasts and pan-cytokeratin+ cells. These cells expressed MUC1 at different intensities. MUC1 expression in tissue histiocytes, fibroblasts, CD4+ and CD8+ T cells, and follicular epithelial cells of FM was significantly higher than the same cell types in the dermal mucinoses (p < 0.001). CD8+ T cells were significantly more involved in expression of MUC1 than all other analysed cell types in FM. This finding was also significant in comparison with dermal mucinoses.
CONCLUSION
Various cell types seem to contribute to mucin production in PCM. Using MFS, we showed that CD8+ T cells seem to be more involved in the production of mucin in FM than in dermal mucinoses, which could indicate that mucin in dermal and follicular epithelial mucinoses have different origins.

Hypothyroidism, a disorder of decreased thyroid hormone secretion diagnosed by increased thyroid stimulating hormone (TSH) and low free triiodothyronine (FT3) and free thyroxine (FT4) levels, is classified as primary and secondary hypothyroidism, depending on the pathology. Raised TSH levels are associated with primary hypothyroidism, while decreased levels of TSH are seen in secondary hypothyroidism. With the easy availability of diagnostic tests, hypothyroidism can be detected and managed early but can be life-threatening if not treated within time. Manifestations of hypothyroidism are dry skin, hoarseness of voice, weight gain, constipation, cold intolerance, fatigue, and lethargy; however, the clinical presentation can differ as per age and sex and person to person. Here, we present one such case, which was brought to the emergency room with a history of altered sensorium, hypotension, and swelling over the bilateral lower limbs and face, with a surprise diagnosis of myxedema crisis. The uniqueness of this case is the omnipresent availability of early diagnosis and treatment in this era. still got a female patient with altered sensorium who was diagnosed to be a myxedema crisis which was given a lesser thought in our provisional diagnosis.
