Workup and Management of Recurrent Attacks of Post-bariatric Hypoglycemia in a Patient With Non-alcoholic Steatohepatitis.

Bariatric surgery is an established treatment option for patients with non-alcoholic fatty liver disease (NAFLD) as well as non-alcoholic steatohepatitis (NASH) and is said to effectively reduce hepatic inflammation as well as steatosis in these patients. However, bariatric surgery is associated with multiple complications, including nutritional deficiencies, malnutrition, post-bariatric hypoglycemia (PBH), anastomotic leaks, and bowel strictures. This case report describes a rare but significant complication of post-bariatric surgery hypoglycemia in a patient with NASH, which started almost six months after Roux-en-Y gastric bypass (RYGB) surgery. This 55-year-old male patient presented with recurrent episodes of severe hypoglycemia, which, on further work-up, were found to be predominantly nocturnal as well as occurring two to three hours after meals. We report the successful treatment of the patient with an unconventional approach using nifedipine and acarbose. Our findings emphasize the importance of careful evaluation of patients who have undergone bariatric surgery, as this complication can occur as early as six months following the bariatric surgery as well as several years after the surgery. Our case report highlights the need for early recognition, relevant workup, and appropriate management of resistant hypoglycemic events using calcium channel blockers and acarbose, thus adding to the existing literature on this topic.

Fluctuating Hyperthyroidism and Hypothyroidism in Graves' Disease: The Swinging Between Two Clinical Entities.

Autoimmune thyroid disorders are frequently encountered in clinical practice and consist of a spectrum ranging from Graves' hyperthyroidism to Hashimoto's hypothyroidism. Generally, patients with autoimmune thyroid disorders will lean towards one end of the spectrum or the other, with fluctuations between hyper- and hypothyroidism rarely seen. This is especially the case when persistent hyperthyroidism occurs after a prolonged period of hypothyroidism. Here, we present a case of a young female patient initially presenting with Graves' disease with a previous history of hypothyroidism.

Painless Subacute Thyroiditis in a Patient With Acute COVID-19 Infection: A Transient Event.

Coronavirus 2019 disease (COVID-19) is a highly contagious infectious disease caused by severe acute respiratory coronavirus 2 (SARS-CoV-2). Although several articles have described the non-respiratory effects of COVID-19 in the past two years, there are few reports of COVID-19 associated with thyroiditis. We present a case of a middle-aged female patient with positive COVID-19 PCR associated with acute pulmonary embolism and thyroiditis. Three months ago, her baseline thyroid profile was normal. Thyroiditis induced elevated free thyroxine (FT4) and decreased thyroid-stimulating hormone (TSH) levels resolved with conservative management within six days.

Subclinical Hypothyroidism Presenting as Myxedema Coma: Case Report and Literature Review.

Myxedema coma is a medical emergency with a high mortality rate. Patients with hypothyroidism may develop myxedema coma if left untreated, although quite rare nowadays owing to regular TSH (thyroid stimulating hormone) monitoring. We present the case of a patient with a known history of subclinical hypothyroidism, defined by normal free T4 (thyroxine) and high TSH, who was found to be in myxedema coma. Clinically, the patient was found to be lethargic, bradycardic, and hypothermic, and in the background of high TSH, myxedema coma was suspected. The patient was admitted to the ICU (Intensive Care Unit) and initially treated with intravenous (IV) hydrocortisone for possible concomitant adrenal insufficiency. This was followed by treatment with IV levothyroxine.

Case Report of Acute Pancreatitis Associated With Combination Treatment of Dulaglutide and Glipizide.

The objective of this report is to discuss a case of drug-induced acute pancreatitis in a patient on a combination of dulaglutide and glipizide. The patient was a 61-year-old African American male with a past medical history of diabetes mellitus type 2 and essential hypertension, who was admitted for acute pancreatitis after presenting with upper abdominal pain. He was initially on glipizide but dulaglutide was added to improve control. The patient was a social drinker and an ex-cigarette smoker. He had serum lipase greater than 900 U/L, serum alcohol was negative, and abdominal computed tomography reported significant pancreatic edema consistent with acute pancreatitis but without features of necrotizing pancreatitis and no evidence of cholelithiasis or choledocholithiasis. His clinical state deteriorated after being complicated by paralytic ileus. He was managed conservatively, improved clinically, and was discharged home. Seeing that the incidence of pancreatitis is higher in patients with diabetes when compared to non-diabetics, it is important to counsel and monitor patients for risk factors of pancreatitis including medications. In the absence of other common causes in this case and considering the temporal relationship between presentation and the addition of dulaglutide to ongoing glipizide regimen, the combination of both drugs may have induced acute pancreatitis.

ALTERNATING THYROID STATUS BETWEEN THYROTOXICOSIS AND HYPOTHYROIDISM IN A PATIENT WITH VARYING ANTITHYROID ANTIBODIES.

OBJECTIVE: Autoimmune pathologies are a growing aspect of medicine. Knowledge about atypical cases is essential. This report will describe a case of unusual, alternating fluctuations in thyroid function. METHODS: We report a case of thyrotoxicosis alternating with hypothyroidism in a 44-year-old, African-American woman and detail the clinical course and management. RESULTS: The patient presented in a mildly thyrotoxic state with features of thyroiditis that resolved soon thereafter. Subsequently, the course shifted toward a hypothyroid state with a thyroid-stimulating hormone (TSH) level of 24.53 µIU/ml (normal range is 0.45 to 4.5 µIU/ml; measured September 5, 2013) and free thyroxine (FT4) of 0.35 ng/dL (normal range is 0.5 to 1.40 ng/dL; measured September 5, 2013). It ensued with alternating hypothyroid and hyperthyroid trajectories for several cycles. Clinical management was adjusted to negotiate each progression. During certain intervals, levothyroxine was increased. At other visits, it was decreased. Periods without medication were observed as well. Furthermore, methimazole and metoprolol were utilized when required. Reversal of the condition occurred repeatedly. The entire course is tracked with over 30 instances of thyroid function measures that included hypothyroid, euthyroid (TSH at 1.54 µIU/mL, FT4 at 1.16 ng/dL) and thyrotoxic states (TSH at <0.005 µIU/mL, FT4 at 2.67 ng/dL). Various antibody titers were elevated including thyroid-stimulating immunoglobulin, thyroid peroxidase antibody, and TSH receptor antibody. Close monitoring of TSH and FT4 allowed for appropriate medication dose adjustment. CONCLUSION: This case highlights the unusual phenomenon of fluctuating thyroid function with autoimmune involvement of thyroid-stimulating immunoglobulin and TSH receptor antibodies. Close follow up aided responsive clinical management throughout the fluctuating clinical course.

Hot and malignant - a case of invasive papillary carcinoma in hyperthyroid patient with hot nodules.

Introduction: Malignant thyroid nodules are clinically euthyroid and appear as cold nodules on scintigraphy. Malignancy in hyper-functioning thyroid nodule is rare. Case report: A 48-year-old male with painless swelling on the right side of his neck for the last 4 months complained of feeling hot all the time, sweating and unintentionally losing about 20 pounds. On physical examination, there was a 3-cm mobile, non-tender mass on the right supra-clavicular area biopsy of which was consistent with metastatic papillary carcinoma of thyroid. Neck imaging showed a cystic mass in the right supra-clavicular fossa region, bilateral neck adenopathy and multiple thyroid nodules. Subsequent thyroid radionuclide scans showed three hyper-functioning nodules, which were later demonstrated to be a follicular variant of papillary microcarcinoma. He was treated with total thyroidectomy followed by radioactive iodine thyroid ablation therapy. Conclusion: Physicians need to be aware and vigilant for the possibilities of malignancy in a hyper-functioning thyroid nodule when evaluating any thyroid nodule.

Gallbladder adenocarcinoma and paraneoplastic parathyroid hormone mediated hypercalcemia.

Parathyroid hormone mediated hypercalcemia is not always exclusively primary hyperparathyroidism and rarely could be due to ectopic parathyroid hormone secretion from tumor cells. We present a case of 86-year-old female with metastatic gall bladder adenocarcinoma diagnosed eight months back who presented with generalized fatigue and poor oral intake and was found to be hypercalcemic with elevated parathyroid hormone levels. Imaging with technetium 99 m sestamibi scintigraphy with dual phase, subtraction thyroid scan (dual isotope scintigraphy), magnetic resonance imaging and ultrasonography did not demonstrate any parathyroid lesion in normal or ectopic sites. We believe that the tumor cells were the source of ectopic parathyroid hormone secretion as we had excluded all the other possibilities with extensive combined imaging thereby increasing the sensitivity of our testing. We report the first case of metastatic gall bladder adenocarcinoma with paraneoplastic ectopic parathyroid hormone secretion.
