A 32-year-old woman presented with persistent vomiting, epigastric pain and weight loss. A sinus tachycardia was the clue to the diagnosis of hyperthyroidism due to Graves' disease. On treatment with propylthiouracil and a beta-blocking agent, her symptoms resolved within one day, even though her free thyroxine level was still high. Hyperthyroidism is an uncommon, but previously reported cause of persistent vomiting.

Hyperemesis gravidarum is an extreme form of nausea and vomiting during pregnancy. Its presenting symptoms include vomiting, disturbed nutrition, electrolyte imbalance, ketosis, extreme weight loss, renal and/or liver damage. It is rare for a hyperemesis gravidarum patient to present with jaundice, hyperthyroidism and idiopathic acute pancreatitis during the same hospitalization period. Here, we report such a case. A 25-year-old pregnant woman without underlying liver or thyroid disease was admitted due to jaundice noted for 2 days at 8 weeks of gestational age. Hyperthyroidism symptoms of tachycardia and finger tremor also bothered her. After treatment with parenteral fluid and antithyroid agents, her clinical condition improved. However, an episode of idiopathic pancreatitis occurred after nausea and vomiting subsided. Bowel rest with parenteral fluid and nutrition supplement was given and the increased pancreatic enzyme level gradually subsided. Follow-up liver and thyroid function were normal after gestational age of 26 weeks. She delivered a healthy female baby without low birth body weight at gestational age of 39 weeks. Rapid diagnosis and supportive care are important for the hyperemesis gravidarum patient with the complication of acute pancreatitis.

A 29-year-old female presented with Basedow's disease manifesting as sudden vomiting, diarrhea, fever over 38 degrees C, transient aphasia, and numbness in her extremities. These symptoms were considered due to cerebral ischemia at a local clinic. Magnetic resonance angiography indicated stenosis of the bilateral distal internal carotid arteries and the bilateral proximal anterior cerebral and middle cerebral arteries. Thyroid swelling and exophthalmos were observed. She was transferred to our hospital. Endocrine function tests showed hyperthyroidism. The diagnosis was Basedow's disease. Her symptoms disappeared after receiving intravenous drip infusion of fluid replacement, and antithyroid and antiplatelet medication. After she became euthyroid, cerebral angiography and magnetic resonance angiography revealed improvement of the stenosis of the cerebral arteries. Stenosis of the terminal portion of the internal carotid artery associated with Basedow's disease is extremely rare. Conservative treatment mainly including antithyroid medications for Basedow's disease, and antiplatelet drugs and intravenous replacement fluid for the ischemic manifestations should be the first choice of treatment unless immediate vascular reconstruction is necessary.

Radioiodine is considered the treatment of choice for hyperthyroidism, but in some situations, methimazole therapy is preferred, such as in cats with pre-existing renal insufficiency. Methimazole blocks thyroid hormone synthesis, and controls hyperthyroidism in more than 90% of cats that tolerate the drug. Unfavorable outcomes are usually due to side effects such as gastrointestinal (GI) upset, facial excoriation, thrombocytopenia, neutropenia, or liver enzyme elevations; warfarin-like coagulopathy or myasthenia gravis have been reported but are rare. Because restoration of euthyroidism can lead to a drop in glomerular filtration rate, all cats treated with methimazole should be monitored with BUN and creatinine, in addition to serum T4, complete blood count, and liver enzymes. Transdermal methimazole is associated with fewer GI side effects, and can be used in cats with simple vomiting or inappetance from oral methimazole. Hypertension may not resolve immediately when serum T4 is normalized, and moderate to severe hypertension should be treated concurrently with-atenolol, amlodipine, or an ACE inhibitor. Alternatives to methimazole include carbimazole, propylthiouracil, or iodinated contrast agents.

Radioiodine is considered the treatment of choice for hyperthyroidism, but in some situations, methimazole therapy is preferred, such as in cats with preexisting renal insufficiency. Unfavorable outcomes from methimazole are usually attributable to side effects, such as gastrointestinal upset, facial excoriation, thrombocytopenia, neutropenia, or liver enzyme elevations. Because restoration of euthyroidism can lead to a drop in glomerular filtration rate, all cats treated with methimazole should be monitored with blood urea nitrogen and creatinine levels in addition to serum thyroxine (T(4)) and a complete blood cell count. Transdermal methimazole is associated with fewer gastrointestinal side effects and can be used in cats with simple vomiting or inappetence from oral methimazole. Hypertension may not resolve immediately when serum T(4) is normalized, and moderate to severe hypertension should be treated concurrently with atenolol, amlodipine, or an angiotensin-converting enzyme inhibitor.

A 31-year-old man admitted with abdominal pain, nauseas, vomiting, jaundice and fever that had began 2 weeks before. He had a history of hyperthyroidism and an irregular treatment with propylthiouracil (PTU) for 2 years. He had stopped PTU when the current symptoms started. The patient presented diffuse goiter, about 120g, FT4 22.7 ng/dL (N: 0.8 - 1.9 ng/dL); THS < 0.002 microUI/mL (N 0.4-5 microUI/mL). Transaminases, serum total and direct bilirubins were increased. He was kept without PTU and propranolol was started and increased until the dose of 480 mg/day. Abdominal ultrasonography was normal and serologic markers for hepatitis A, B and C pointed to acute virus B hepatitis. The patient presented a worse of hepatic function and elevated thyroid hormones levels. To avoid the future need of antithyroid drugs, to get a fast normalization of thyroid hormones levels and because of the goiter size thyroidectomy was recommended. The patient underwent one therapeutic plasmapheresis session just before the surgery. A total thyroidectomy was performed without complications. At the 5th day after surgery the patient presented improvement of hepatic function and low FT4 serum levels. We concluded that preexisting hyperthyroidism may aggravate or perpetuate a hepatic failure caused for acute viral hepatitis and plasmapheresis is a rapid, reliable and effective way to lower thyroid hormones serum levels, allowing a successful thyroidectomy in patients with severe thyrotoxicosis.

Rhabdomyolysis is an acute skeletal muscle disorder characterized by altered integrity of the cell membranes of muscle fiber cells. It can be related to a variety of factors: muscular trauma, muscle enzyme deficiencies, infections, drugs, toxins, alcohol ingestion, endocrinopathies and electrolyte imbalances such as hypokalemia. We report the case of a 46-year-old woman admitted to the Emergency Department for frequent episodes of vomiting associated with food intake in the last two weeks, general muscular weakness and myalgia. Physical examination on admission was unremarkable, except for a symmetrical and dominantly proximal muscular weakness of all four extremities. Blood pressure was 116/70 mmHg with a sinus bradycardia (53 beats/min) on the electrocardiogram. Laboratory tests showed a metabolic alkalosis with marked hypokalemia (K+= 1.9 mEq/l) and elevation of muscular enzymes (myglobin= 993 ng/ml, troponin T= 0,10 ng/ml e CK= 1113 U/l). No symptoms of recurrent rhabdomyolysis were reported, patient denied alcohol consumption and there was not clinical evidence of hyperthyroidism. A iatrogenic etiology could not be excluded for certain because patient was in therapy with lansoprazole (Naranjo algorithm 3/13) but, revealing medical history that she underwent a laparoscopic adjustable gastric banding for the treatment of a severe obesity, we focused our attention on hypokalemia, due to persistent vomiting. Fasting, administration of metoclopramide and infusion of potassium chloride resulted in steady improvement of clinical conditions and normalization of electrolyte imbalance. At the clinical follow-up of three months, after partial deflation of the gastric banding, the patient was asymptomatic with muscular enzymes and potassium levels in the normal range. Authors discuss the pathophysiologic mechanisms of these alterations.

In situations where the cause of hypokalemia is not obvious, measurement of urinary potassium excretion and blood pressure and assessment of acid-base balance are often helpful. A random urine potassium-creatinine ratio (K/C) less than 1.5 suggests poor intake, gastrointestinal losses, or a shift of potassium into cells. If hypokalemia is associated with paralysis, we should consider hyperthyroidism, familial or sporadic periodic paralysis. Metabolic acidosis with a urine K/C ratio less than 1.5 suggests lower gastrointestinal losses due to diarrhea or laxative abuse. Metabolic acidosis with K/C ratio of 1.5 higher is often due to diabetic ketoacidosis or type 1 or type 2 distal renal tubular acidosis. Metabolic alkalosis with a K/C ratio less than 1.5 and a normal blood pressure is often due to surreptitious vomiting. Metabolic alkalosis with a higher K/C ratio and a normal blood pressure suggests diuretic use, Bartter syndrome, or Gitelman syndrome. Metabolic alkalosis with a high urine K/C ratio and hypertension suggests primary hyperaldosteronism, Cushing syndrome, congenital adrenal hyperplasia, renal artery stenosis, apparent mineralocorticoid excess, or Liddle syndrome. Hypomagnesemia can lead to increased urinary potassium losses and hypokalemia. The differential rests upon measurement of blood magnesium, aldosterone and renin levels, diuretic screen in urine, response to spironolactone and amiloride, measurement of plasma cortisol level and the urinary cortisol-cortisone ratio, and genetic testing.

Thyrotoxic crisis during pregnancy is a rare condition, but because of the danger it poses for the mother and fetus, every physician should be able to diagnose and treat it. When not recognized or incorrect treated hyperthyroidism, which is not easy to diagnose during pregnancy, is usually the basis for thyrotoxic storm. Serious conditions such as Graves' disease or multinodular goiter have to be distinguished from transient hyperthyroidism. Symptoms, such as: heat intolerance, hyperexia, emesis, tachycardia, increased pulse pressure and emotional liability should be considered cautiously because they are characteristic both for hyperthyroidism and for pregnancy. Interpretation of laboratory results need to take physiological changes during pregnancy into account--during the first trimester a low TSH serum concentration should be expected, whereas in the third trimester the free thyroxine (fT4) concentration decreases. Some conditions characteristic for pregnancy may be causative for thyrotoxic crisis: preeclampsia, placenta previa, labour induction, labour and cessarian section. Usually a hypermetabolic state has a characteristic, severe course but the possibility of monosystemic presentation must be kept in mind, because it is difficult to diagnose. Management of thyrotoxic crisis includes specific (thyrostatic agents, iodine preparations, adrenolytics, plasmaferesis) and supportive treatment. Thyrostatic agents (thiamazole and propylthiouracyl) can cross the placental barrier and similarly to iodine preparations can interfere with the pituitary-thyroid axis of the fetus. Additionally, thiamazole may cause specific embryopathy and should be considered as a second-line treatment. Adrenolytics affect the placental and uterine functions, and in high doses causes newborn hypoglycemia and bradycardia. A surgical approach is linked to an increased rate of preterm labour and miscarriage, but long-term effects are good.

Thyroid hemiagenesis is a rare anomaly due to failure of development of one thyroid lobe during embryological life. A lot of thyroid disorders may accompany thyroid hemiagenesis. In this report, we present a case of thyroid hemiagenesis, who had moderate hypercalcemia due to Graves' disease. A 43-year-old woman presented with weight loss of more than 5 kg within one month, heat intolerance, and increased sweating. For the past month, she had been troubled by intermittent symptoms of vomiting, thirst, and constipation. On examination, she had tachycardia with no signs of dehydration. Pulse rate was 110 per minute. She had fine tremor, proximal muscle weakness, and asymmetric smooth goiter and hyperplasia in the right thyroid gland. Thyroid function tests confirmed the diagnosis of hyperthyroidism. Although hypercalcemia may be detected in patients with thyrotoxicosis, to the best of our knowledge, this is the first case report of thyroid hemiagenesis accompanying hypercalcemia due to thyrotoxicosis.
