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.

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.

Polyglandular autoimmune syndrome (PAS) is a rare disorder characterized by the autoimmune destruction of multiple endocrine glands. Type II PAS is the most common of the PAS subtypes and is characterized by Addison's disease, autoimmune thyroid disease, and type I diabetes mellitus. Disease manifestations are predominantly seen in young adulthood with an emerging endocrine disorder; however, a host of other autoimmune conditions can also be present before endocrine organ dysfunction. Due to the complex nature of presentation and management, an important consideration in patient care involves a multidisciplinary team with the addition of an endocrinologist. A 21-year-old African American woman with a medical history of PAS-II presented during three hospitalizations with adrenal crisis, diabetic ketoacidosis (DKA), and myxedema. The common theme across admissions entails a spectrum of adrenal dysfunction, including shock, as well as glucose and thyroid abnormalities. During her first hospitalization, the patient presented with hypotension, hyperglycemia, and hypothyroidism. She received aggressive IV fluid resuscitation, an insulin drip, electrolyte repletion, an up-titration of levothyroxine, and stress-dose corticosteroids. In the second hospitalization, she also had hypotension and electrolyte derangements, along with hypoglycemia and myxedema. She received glucose management, thyroid hormone replacement, and stress steroids again. The third hospitalization involved flu-like symptoms and a positive SARS-CoV-2 test. She was managed similarly for hypotension, hyponatremia, and hyperglycemia. In this case, she presented with non-gap metabolic acidosis and required a bicarbonate drip for a short period. She did not receive antibiotics across these three admissions. We present three hospitalizations where adrenal, pancreatic, and thyroid derangements were seen and managed. It is known that most general providers other than endocrinologists are not comfortable with the management of disease manifestations of PAS-II; therefore, we provide a case review to address the standard of care management and guidelines with further discussion. This patient's maintenance care was complicated by a lack of adherence to outpatient medications, leading to recurrent hospitalizations. We also endorse the importance of doctors pursuing endocrinology fellowships, especially due to the observed waning number of graduates. An endocrinologist's availability and involvement in the care of patients with complex endocrine issues lead to improved outcomes.

Multiple vitamin deficiencies together with endocrinopathy may be encountered in individuals presenting with critical illness. Following the surprise postmortem diagnosis of concomitant scurvy, Wernicke, and hypothyroidism in an elderly woman presenting with a mix of atypical symptoms, patients considered at risk were tested for TSH, vitamin C, and thiamin levels. Between September 1, 2018, and December 31, 2022, 801 vitamin C levels in 679 patients were measured in our rural hospital and 309 (39%) were found <0.4 mg/dL. In this population, 39% of 626 thiamin levels were found to be low. Twenty-two patients with vitamin C and/or thiamin deficiency and elevated TSH levels were identified. Two patients died from scurvy; one also had myxedema. The incidence of vitamin C and thiamin deficiency in our patient population was higher than expected. Further studies should determine if this is unique to our rural setting or part of a bigger trend associated with poor dietary choices.

Myxedema coma is a rare and life-threatening endocrine emergency characterized by abnormalities in multiple organ systems. A 32-year-old woman with prolonged undiagnosed severe hypothyroidism was referred to our hospital owing to lower abdominal pain and menopause for more than 3 months. She underwent exploratory laparotomy and induced abortion under general anesthesia, and developed severe hypoxemia after extubation. She was diagnosed with myxedema coma, and was subsequently discharged with a good prognosis following treatment. This case suggests that myxedema coma should be considered a potential etiology of peri-operative hypoxemia. The findings in this case emphasize the importance of anesthesiologists' comprehensive understanding of myxedema coma. Prompt diagnosis followed by treatment is essential to reduce the mortality rate associated with this condition.

La Revue de Medecine Interne Dec 2023Pretibial myxedema is a rare manifestation of Graves' disease, and pseudotumoral forms may be confused with lower limb lymphedema.
INTRODUCTION
Pretibial myxedema is a rare manifestation of Graves' disease, and pseudotumoral forms may be confused with lower limb lymphedema.
OBSERVATIONS
We reported 3 cases of pretibial myxedema in 2 women and 1 man, aged 72, 66, and 49 years, treated for Graves' disease 3, 25 and 32 years previously. Two patients were active smokers. Lymphedema diagnosis of the lower limbs was suspected in the presence of bilateral pseudotumoral lesions of the feet, toes and ankles and the presence of a Stemmer's sign (skin thickening at the base of the 2nd toe, pathognomonic of lymphedema). Lymphoscintigraphy in one case was normal, not confirming lymphedema.
CONCLUSION
Pretibial pseudotumoral myxedema is a differential diagnosis of lower limb lymphedema. This diagnosis is confirmed by questioning the patient about preexisting Graves' disease, the underlying etiology, to decide the appropriate treatment and to encourage cessation of smoking, which is a risk factor for pretibial myxedema.

Myxedema coma is a rare and life-threatening manifestation of severe hypothyroidism. Myxedema refers to altered mental status observed in these patients. Clinical characteristics observed include hypothermia, bradycardia, respiratory failure, hyponatremia, and altered mental status. We present the case of a 57-year-old female who was brought into the hospital with a history of collapse and a long lie. On initial assessment, she was hypothermic, hypotensive, bradycardic, and hypoglycemic with elevated infection markers, acute kidney injury, and electrolyte derangement. Her thyroid function tests on admission were severely impaired with a TSH (thyroid stimulating hormone) level of 144.46 mU/L and Free T4 (thyroxine) levels of 3.4 pmol/L. She was admitted to the intensive care unit and was started on intravenous antibiotics, intravenous liothyronine, oral levothyroxine, and intravenous hydrocortisone. Initially, her hypothermia and bradycardia were slow to respond to treatment measures, but following the introduction of liothyronine, she showed marked improvement. Over the next few days, her infection markers improved, her acute kidney injury resolved, and her thyroid function tests normalized. Liothyronine was stopped after 6 days, levothyroxine was continued at her regular dose of 175 micrograms, and she was safely discharged with outpatient endocrinology follow-up.

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.

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.

Myxedema crisis (MC) refers to an unusual state of regulatory dysfunction precipitated by uncontrolled hypothyroidism. The pathogenic consequences of MC are broad and may contribute to significant bodily decompensation across multiple organ systems. However, shock-induced ischemic optic neuropathy (SION) in this setting has not been reported previously. Here, we present the case of a 76-year-old female with presumed bilateral optic neuropathy following abdominal surgery. The patient experienced a prolonged and complicated postoperative course in which she remained off supplemental levothyroxine. Subsequently, her clinical status deteriorated until she met diagnostic criteria for acute decompensated hypothyroidism (MC). Upon awakening from a comatose state, she reported significant vision loss. A neuro-ophthalmologic evaluation later confirmed significant constriction of her visual fields, optic disc pallor, and global retinal nerve fiber layer loss consistent with nonarteritic ischemic optic neuropathy.
