ABSTRACT
Cholestyramine (CS) is an ion exchange resin, which binds to iodothyronines and would lower serum thyroid hormone level. The use of CS added to conventional antithyroid drugs to control thyrotoxicosis has been applied since 1980's, and several studies indicate that using CS in combination with methimazole (MZ) produces a more rapid decline in serum thyroid hormones than with only MZ treatment. Our recent retrospective review of five patients taking high dose MZ and CS, compared to age-, gender-, initial free thyroxine (T4) level-, and MZ dose-matched 12 patients with MZ use only, showed more rapid decline of both free T4 and triiodothyronine levels without more adverse events. CS could be safely applicable short-term adjunctive therapy when first-line antithyroid medications are not enough to adequately control severe thyrotoxicosis or side effects of antithyroid drug would be of great concern.

BACKGROUND: This study aimed to evaluate the effect of sitagliptin, an oral dipeptidyl peptidase-4 inhibitor, on insulin secretion and glucagon suppression in Korean subjects with type 2 diabetes mellitus. METHODS: Twenty-four subjects underwent a 75-g oral glucose tolerance test (OGTT) before and after 6 months of sitagliptin treatment. Sitagliptin, insulin, and sulfonylurea were withdrawn for 3 days before OGTT to eliminate any acute effects on beta-cell insulin or alpha-cell glucagon secretion. Venous samples were drawn five times during each OGTT to measure plasma glucose, insulin, and glucagon. Indices on insulin secretion and resistance were calculated. RESULTS: Early phase insulin secretion, measured by the insulinogenic index significantly increased after 6 months of sitagliptin treatment, especially in the higher baseline body mass index group and higher baseline glycosylated hemoglobin (HbA1c) group. There were no significant differences in the insulin resistance indices before and after sitagliptin treatment. Although no significant differences were observed in the absolute levels of glucagon and the glucagon-to-insulin ratio, there was a significant reduction in the percentile change of glucagon-to-insulin ratio at 30- and 120-minute during the OGTT. CONCLUSION: Although the HbA1c level did not decrease significantly after 6 months of sitagliptin treatment, an increase in insulin secretion and reduction in early phase postprandial plasma glucagon-to-insulin ratio excursion was confirmed in Korean subjects with type 2 diabetes.

Diabetic neuropathic cachexia (DNC) is one of the rarest presentations of diabetic neuropathy associated with profound weight loss. A 50-year-old Korean woman with poorly controlled type 2 diabetes complained of intractable pain in the trunk and lower extremities, and total body weight loss of 17% over a 6 month period. The patient's symptoms persisted after glucose control and various medications for neuropathic pain. A diagnosis of DNC was made based on the rapid onset of severe pain, polyneuropathy, and marked weight loss without evidence of end organ disease other than mild retinopathy, and the exclusion of other possible causes. Spontaneous improvement of the patient's neuropathic pain and gradual weight gain occurred after 6 months of supportive care. Since the original report of DNC, 31 cases have been published in the English-language literature; however, ours is the first reported case in Korea. Clinicians must be aware of this debilitating complication of diabetes because of its severity and rapid progression.

Human infection caused by Shewanella algae is rare, which usually occurred after direct contact with seawater or ingestion of raw seafood in the immunocompromised host. There have been anecdotal reports about Shewanella infections in human, but their pathogenic role and microbiologic data are limited. Here, we report a fatal case of spontaneous bacterial peritonitis with bacteremia due to S. algae in a 57-year-old male with liver cirrhosis who had no history of exposure to seawater or raw seafood. Polymicrobial infection with Streptococcus mitis and Escherichia coli was combined and the patient died in spite of early appropriate antimicrobial therapy and early goal-directed therapy for sepsis.

Spontaneous pneumothorax occurs in up to 35% of patients with Pneumocystis jirovecii pneumonia. However, spontaneous pneumomediastinum and pneumopericardium are uncommon complications in patients infected with human immunodeficiency virus, with no reported incidence rates, even among patients with acquired immunodeficiency syndrome (AIDS) and P. jirovecii pneumonia. We report a case of spontaneous pneumomediastinum, pneumopericardium, and pneumothorax with respiratory failure during treatment of P. jirovecii pneumonia in a patient with AIDS; the P. jirovecii infection was confirmed by performing methenamine silver staining of bronchoalveolar lavage specimens. This case suggests that spontaneous pneumomediastinum and pneumopericardium should be considered in patients with AIDS and P. jirovecii pneumonia.

Extraintestinal manifestations are not uncommon in Crohn's disease, and a thromboembolic event is a disastrous potential complication. Deep vein thrombosis is the most common manifestation of a thromboembolic event and typically occurs in association with active inflammatory disease. Peripheral neuropathy in Crohn's disease has rarely been reported and is considered an adverse effect of metronidazole therapy. Here, we describe a patient who was initially diagnosed with Crohn's disease complicated with deep vein thrombosis and ulnar neuropathy without metronidazole exposure. The simultaneous occurrence of these complications in the early stage of Crohn's disease has never been reported in the English literature.

Eosinophilic gastroenteritis is an unusual disease that is associated with various clinical gastrointestinal manifestations. Its severity depends on the area involved as well as the wall layer involved. Eosinophilic gastroenteritis often causes abdominal pain, nausea, vomiting and diarrhea. To date, there has been an extremely rare case of eosinophilic gastroenteritis with systemic symptoms, such as fever or lymphadenopathy (LAP). We experienced a case of a 68-year-old-woman with fever and abdominal pain. Abdominal computed tomography revealed diffuse wall thickening of the gastric antrum as linitis plastica. Multiple hot uptakes of lymph nodes were visualized on fludeoxyglucose-positron emission tomography. The gastric biopsy pathological report demonstrated eosinophilic infiltration without malignant cells. We could not exclude malignancy and performed an exploratory laparoscopy. A lymph node specimen showed reactive hyperplasia, and her illness was finally diagnosed as eosinophilic gastroenteritis. Herein, we report the case with a brief review.

BACKGROUND/AIMS: Revaprazan (Revanex(R)) is a novel proton pump inhibitor (PPI) that has a somewhat different effect on proton pump compared with the other PPI's, also (called as 'acid pump antagonist'). We aimed to examine the false negative rate of 13C-urea breath test (UBT) in the patients with Helicobacter pylori (H. pylori) associated peptic ulcer disease who were treated with revaprazan and evaluate the anti-urease activity of revaprazan. METHODS: Total 55 patients were enrolled in this study. They received EGD examination between January 2009 and December 2009 and diagnosed histologically as H. pylori associated peptic ulcer disease. All patients took revaprazan only. Three patients were excluded because of underlying chronic disease and inappropriate breath sampling. The remaining 52 patients had UBT at 0, 2 and 4 weeks of revaprazan use. After 2 weeks of the cessation of revaprazan, they had the fourth UBT. RESULTS: At 2 and 4 weeks, the false negative rates of UBT were 5.8% and 23.1%, respectively (p=0.05). After 2 weeks of the cessation, the cases of the false negative result were five. Four out of five patients had prolonged negative results on two or three successive tests, and baseline 13C difference value did not predict the false negative results. CONCLUSIONS: False negative results of UBT were common and increased with prolonged use of acid pump antagonist. As PPI, it had also anti-urease activity and most patients (47/52, 90.4%) reverted to positive results by 2 weeks after the cessation of taking the medication.
