Down syndrome (DS) is the most common chromosomal disorder in live-born infants, often associated with intellectual disability and various medical conditions, including thyroid dysfunction. Hashimoto's thyroiditis (HT), an autoimmune subtype, is a leading cause of acquired hypothyroidism in DS children. Severe hypothyroidism can precipitate myxedema, a critical condition linked to complications like pericardial effusion and cardiac tamponade. This case study presents a nine-year-old male with DS who was admitted for acute respiratory distress exhibiting classic signs of myxedema. Initial investigations revealed severe hypothyroidism and significant pericardial effusion. Surgical pericardiotomy drained 800 mL of fluid, confirming myxedema secondary to HT. Levothyroxine therapy led to progressive improvement, resolving myxedematous infiltrate and associated symptoms within a month. Follow-up at 12 months demonstrated sustained improvement with normalized thyroid function and no clinical disease activity. This case highlights an atypical presentation of HT in a DS child with cardiac pre-tamponade.

Assessing the relationship between psoriasis and thyroid dysfunction through two sample MR analysis.Archives of Dermatological Research Jun 2024The association between psoriasis and hyperthyroidism/hypothyroidism remains inconclusive, with conflicting findings in prior studies.
BACKGROUND
The association between psoriasis and hyperthyroidism/hypothyroidism remains inconclusive, with conflicting findings in prior studies.
OBJECTIVES
This study employs Mendelian randomization methods to assess the potential relationship.
METHODS
Given the inability to accurately observe the link between psoriasis and thyroid dysfunction, we prioritized utilizing known genetic variants to investigate the potential impacts of the disease.We analyzed data from genome-wide association studies (GWASs), FinnGen, and UK Biobank to extract information on psoriasis, hyperthyroidism, and hypothyroidism. Three MR approaches (MR Egger, weighted median, and inverse variance weighted) were used to scrutinize the causal link.
RESULTS
Our analysis revealed no correlation between psoriasis and hyperthyroidism/hypothyroidism. However, vulgar psoriasis and guttate psoriasis were associated with hypothyroidism/myxedema (IVW odds ratio (OR) = 1.00, 95% confidence interval (CI) = 1.00-1.00, P = 2.53E-03), and Graves' disease (IVW OR = 0.86, 95% CI = 0.72-1.01, P = 4.75E-02).In a subsequent analysis, we observed that hypothyroidism with mucinous edema showed no correlation with Graves' disease in the opposite(P = 9.33E-01).
CONCLUSION
This MR analysis suggests no association between psoriasis and thyroid dysfunction, but highlights associations of vulgar/guttate psoriasis with hypothyroidism/myxedema and Graves' disease. In clinical practice, diagnosing guttate psoriasis requires vigilance for associated risks from hypothyroidism and Graves' disease. For patients with both vulgar psoriasis and hypothyroidism, careful monitoring for mucinous edema is crucial, as it may signal a hypothyroid crisis.

This study details the development of severe post-partum hypothyroidism exacerbating psychogenic non-epileptiform seizures (PNES) and culminating in myxedema coma. A 29-year-old female with a history of anxiety, attention-deficit/hyperactivity disorder (ADHD), and post-partum depression presented with confusion, aphasia, and severe bilateral leg cramping five months following vaginal delivery. Initial laboratory tests indicated elevated creatine kinase (CK) levels, suggestive of non-traumatic rhabdomyolysis. Subsequent seizure-like episodes and the absence of epileptiform activity on the electroencephalogram (EEG) raised suspicions of PNES. Further investigation upon readmittance to the hospital revealed a thyroid-stimulating hormone (TSH) level of 216 mIU/L (range: 0.4-4.0 mIU/L), free thyroxine (T4) level of 0.2 ng/dL (range: 0.8-1.8 ng/dL), and a CK level of 2083 U/L (range in females: 30-150 U/L), indicating severe hypothyroidism with myopathy. Reintroducing levothyroxine (Synthroid), which was previously discontinued during pregnancy, rapidly resolved her symptoms, supporting suspicions that her non-epileptic seizures and myopathy were both caused by her underlying severe post-partum hypothyroidism. She was maintained on levothyroxine with only one seizure-like episode following hospital discharge. This case illustrates the importance of a thorough endocrine assessment in patients with neuropsychiatric presentations, particularly in the peripartum period. It highlights the potential for severe thyroid dysfunction to manifest as PNES, emphasizing the complexity of diagnosing and managing such cases. The findings advocate for a multidisciplinary approach to evaluating post-partum females with neurological and psychiatric symptoms and provide evidence for the link between thyroid disorders and PNES, advocating for a nuanced approach in similar clinical scenarios.

Pleural effusions can be secondary to several different etiologies. Sometimes, they can be related to hypothyroidism. We present a case of massive pleural effusion resulting from hypothyroidism. A 75-year-old male with a history of liver cirrhosis, hypothyroidism, and medication non-adherence presented to the emergency department (ED) with shortness of breath and altered mental status. Physical exam and chest imaging were consistent with right-sided pleural effusion. Effusion was exudative. Multiple recurrences complicated the hospitalization despite thoracentesis and pleurodesis. Labs revealed hypothyroidism, and finally, the patient was started on hormone replacement, resulting in the resolution of the effusion. Pleural effusion is a rare manifestation of hypothyroidism, thought to be mediated by vascular endothelial factors. Pleural fluid analysis shows both exudative and transudative patterns. Hormonal replacement is the mainstay of treatment. Clinicians need to be aware of the rare etiologies of pleural effusion. Depending on the patient's presentation, due work-up should be done to ensure a timely diagnosis and management.

Therapy with thyroid hormones normally is restricted to substitution therapy of patients with primary or secondary hypothyroidism. Typically, thyroid hormones are given orally. There are few indications for intravenous use of thyroid hormones. Indications for parenteral application are insufficient resorption of oral medications due to alterations of the gastrointestinal tract, partial or total loss of consciousness, sedation in the intensive care unit or shock. In almost all cases, levothyroxine is the therapy of choice including congenital hypothyroidism. In preterm infants with an altered thyroid hormone status, studies with thyroid hormones including intravenous liothyronine showed a normalisation of T3 levels and in some cases an amelioration of parameters of ventilation. A benefit for mortality or later morbidity could not be seen. Effects on neurological improvements later in life are under discussion. Decreased thyroid hormone levels are often found after cardiac surgery in infants and adults. Intravenous therapy with thyroid hormones improves the cardiac index, but in all other parameters investigated, no substantial effect on morbidity and mortality could be demonstrated. Oral liothyronine therapy in these situations was equivalent to an intravenous route of application. In myxoedema coma, intravenous levothyroxine is given for 3 to 10 days until the patient can take oral medication and normal resorption in the gastrointestinal tract is achieved by restoring at least peripheral euthyroidism. Intravenous levothyroxine is the standard in treating patients with myxoedema coma. A protective effect on the heart of i.v. levothyroxine in brain-dead organ donors may be possible.

Myxedema psychosis (MP), a rare psychiatric manifestation of hypothyroidism, presents significant diagnostic and therapeutic challenges. This case report details the presentation, diagnosis, and successful management of a 60-year-old woman with MP, who was initially admitted to the psychiatric department for new-onset psychosis following the cessation of hormone replacement therapy after a subtotal thyroidectomy performed 20 years prior. Despite the rarity of psychosis as an initial presentation of hypothyroidism, this case underscores the critical importance of considering endocrine disorders in the differential diagnosis of unexplained psychotic symptoms. The clinical findings included a polymorphic delusional system and auditory hallucinations, without significant abnormalities on magnetic resonance imaging. Elevated thyroid-stimulating hormone (TSH) levels confirmed hypothyroidism, leading to the diagnosis of MP. Treatment with l-thyroxine resulted in complete resolution of symptoms in three weeks, highlighting the efficacy of hormone replacement therapy. This case contributes to the limited literature on MP and echoes the need for awareness among clinicians to ensure timely and accurate diagnosis and treatment.

Comparative Study
Bipolar disorder is associated with increased rates of many physical disorders, but the effects of medication are unclear. We systematically investigated the associations between sustained use of first line maintenance agents, lithium versus lamotrigine and valproate, and the risk of physical disorders using a nation-wide population-based target trial emulation covering the entire 5.9 million inhabitants in Denmark. We identified two cohorts. Cohort 1: patients with a diagnosis of bipolar disorder prior to first purchase (N = 12.607). Cohort 2: all 156.678 adult patients who had their first ever purchase (since 1995) of either lithium, lamotrigine or valproate between 1997 and 2021 regardless of diagnosis. Main analyses investigated the effect of sustained exposure defined as exposure for all consecutive 6-months periods during a 10-year follow-up. Outcomes included a diagnosis of incident stroke, arteriosclerosis, angina pectoris, myocardial infarction, diabetes mellitus, myxedema, osteoporosis, dementia, Parkinson's disease, chronic kidney disease and cancer (including subtypes). In both Cohorts 1 and 2, there were no systematic statistically significant differences in associations between sustained use of lithium versus lamotrigine and valproate, respectively, and any physical disorder, including subtypes of disorders, except myxedema, for which exposure to lithium increased the absolute risk of myxedema with 7-10 % compared with lamotrigine or valproate. In conclusion, these analyses emulating a target trial of "real world" observational register-based data show that lithium does not increase the risk of developing any kind of physical disorders, except myxedema, which may be a result of detection bias.

Myxedema is a medical emergency with high mortality rates if not treated aggressively. Here, we present a middle-aged female with complaints of generalized body swelling for one year, shortness of breath, hoarseness of voice, neck swelling, and cough for 20 days. The patient was diagnosed to be having severe hypothyroidism with polyserositis. Contrast-enhanced computed tomography (CECT) of the neck and thorax revealed extensive soft tissue edema causing airway narrowing, bilateral pleural effusion, moderate pericardial effusion, and features of atypical pneumonia. The patient was started on levothyroxine and antibiotics as per cultures to which she had initially improved; however, she developed ventilator-associated pneumonia leading to sepsis, acute respiratory distress syndrome followed by refractory type 1 respiratory failure and succumbed.

Review
We report two cases of myxoedema coma that presented to the acute medical take with severe bradycardia. These patients were initially misdiagnosed as bradyarrhythmia of primary cardiac origin. They were then diverted to the cardiology service at another district general hospital (DGH) for admissions. Both cases were subsequently diagnosed with myxoedema coma having screened thyroid function tests on arrival at the cardiology unit. Despite being treated for myxoedema coma, both patients unfortunately succumbed to the disease and later died in the hospital. These cases highlight that clinical suspicion and recognition of myxoedema coma remain significant challenges in a developed world despite readily available and highly sensitive thyroid hormone assays.

BACKGROUND
Graves' disease is the autoimmune activation of the thyroid gland causing diffuse enlargement and hyperfunction of the gland. Manifestations of Graves' disease are multisystemic and include thyroid orbitopathy; pretibial myxedema, also referred to as thyroid dermopathy; and thyroid acropachy, described as a severe form of thyroid dermopathy. Our paper focuses on an atypical case of thyroid dermopathy.
CASE PRESENTATION
An 11-year-old Saudi male presented with a prominent diffuse goiter and exophthalmos. Investigations were consistent with a diagnosis of Graves' disease. The physical exam showed diffuse, non-pitting swelling of the ankle and penis, mimicking a lymphatic malformation. Further, multiple nodules were found on the hands and feet. Treatment of the nodules with cautery resulted in more severe nodules.
CONCLUSION
This report describes rare presentations of thyroid dermopathy mimicking lymphatic malformation. The Koebner phenomenon can explain this patient's atypical presentations. Intralesional injections of triamcinolone and total thyroidectomy showed clear improvement.
