AbstractAbstract PDF
Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

AbstractAbstract PDF
Hyponatremia, the most common electrolyte disorder, has been rarely reported as causing rhabdomyolysis. Osmotic demyelination syndrome (ODS), a demyelinating disease of the central pons and/or other areas of the brain, is infrequently reported as associated with rapid correction of hyponatremia. This paper reports a case of ODS after correction of severe hyponatremia complicated by rhabdomyolysis. A 47-year-old female with a history of chronic alcoholism presented herself at the hospital with altered consciousness after three days of nausea and vomiting. She was on a thiazide diuretic for essential hypertension. Her blood tests upon her hospital admission showed hyponatremia (Na+ 98 mEq/L), hypokalemia (K+ 3.0 mEq/L), and elevation of her serum creatine phosphokinase (3,370 IU/L) with an increase in her serum myoglobin level 11,267 ng/mL). She was treated with intravenous fluid therapy that included isotonic and hypertonic salines along with potassium chloride. She became more alert, and her neurological condition gradually improved after the first five days of her therapy. On the ninth day after her admission, she developed progressive quadiaresis associated with dysarthria, dysphagia, and dystonia despite the resolution of her hyponatremia. Magnetic resonance imaging of her brain on 16th day revealed symmetrical areas of signal hyperintensity in her central pons, basal ganglia, and precentral gyrus in T2-weighted images, which are consistent with ODS. Her neurological symptoms steadily improved after six weeks with only supportive treatment and rehabilitation.
