A Case of Painful Hashimoto Thyroiditis that Mimicked Subacute Thyroiditis / 전남의대학술지

Hashimoto thyroiditis (HT) is an autoimmune thyroid disorder that usually presents as a diffuse, nontender goiter, whereas subacute thyroiditis (SAT) is an uncommon disease that is characterized by tender thyroid enlargement, transient thyrotoxicosis, and an elevated erythrocyte sedimentation rate (ESR). Very rarely, patients with HT can present with painful, tender goiter or fever, a mimic of SAT. We report a case of painful HT in a 68-year-old woman who presented with pain and tenderness in a chronic goiter. Her ESR was definitely elevated and her thyroid laboratory tests suggested subclinical hypothyroidism of autoimmune origin. (99m)Tc pertechnetate uptake was markedly decreased. Fine needle aspiration biopsy revealed reactive and polymorphous lymphoid cells and occasional epithelial cells with Hurthle cell changes. Her clinical symptoms showed a dramatic response to glucocorticoid treatment. She became hypothyroid finally and is now on levothyroxine therapy.

A Case of Kikuchi Disease Accompanied with Bilateral Retinal Vasculitis

Kikuchi disease, also called histiocytic necrotizing lymphadenitis, is an uncommon, idiopathic and generally self-limited disease, characterized by cervical lymphadenopathy. It can present systemic symptoms and signs, but ocular involvement is unusual. We report a 35-year-old woman who presented sudden decreased visual acuity and a swollen lymph node on the left side of her neck. On laboratory findings, there were no evidences of infection, autoimmune disease and systemic vasculitis. She was diagnosed with Kikuchi disease and bilateral retinal vasculitis by histologic analysis of lymph node, fundoscopy and fluorescein angiography.

Acute Extensive Ischemic Gastroduodenitis in a Patient with End Stage Renal Disease: A Case Report / 대한신장학회지

Acute extensive ischemic gastroduodenitis is a very rare disease because the stomach and duodenum normally have enough blood supply to the upper gastrointestinal (GI) tract and the submucosal vascular plexus. The major causes of upper GI hemorrhage in end stage renal disease (ESRD) patients include erosive gastritis, erosive esophagitis, esophageal ulcer and peptic ulcer. Ischemic gastritis and duodenitis have been reported to be rare as a cause of upper GI bleeding in ESRD patients. We report a case of acute extensive ischemic gastroduodenitis caused by septic shock with severe mesenteric calcification in a patient with ESRD undergoing maintenance hemodialysis.

Delftia acidovorans Isolated from the Drainage in an Immunocompetent Patient with Empyema / 결핵및호흡기질환

Delftia acidovorans is a gram-negative motile rod found ubiquitously in soil and in water. Confirmed isolation from clinical infections is rare, and has been documented mostly in immunocompromised patients or those with indwelling catheters. A 53-year-old man was referred for the evaluation of a huge mass-like lesion found incidentally by chest X-ray. The lesion occupied more than half of the right lung and was diagnosed as a large loculated pleural effusion by CT scan. Bloody pus was drained through a percutaneous catheter, and D. acidovorans, identified by the Vitek GN card and confirmed by amplification of 16S ribosomal RNA and sequencing analysis, was isolated repeatedly from the drained pus. The patient was treated with imipenem/cilastatin to which the organism was sensitive. This is a rare report of chronic empyema associated with D. acidovorans in the respiratory system of an immunocompetent patient.
