Dobutamine stress echocardiography for evaluating cirrhotic cardiomyopathy in liver cirrhosis / 대한간학회지

BACKGROUND/AIMS: The blunted ventricular systolic and diastolic contractile responses to physical and pharmacological stress in cirrhosis are termed cirrhotic cardiomyopathy (CCM). CCM has been known to involve multiple defects in the beta-adrenergic signaling pathway. The aim of this study was to determine whether cirrhotic patients have blunted cardiac responses to catecholamine stimulation through dobutamine stress echocardiography (DSE). METHODS: Seventy-one cirrhotic patients with normal left ventricular (LV) chamber size and ejection fraction were enrolled. The LV systolic and diastolic functions were evaluated by two-dimensional and Doppler echocardiography at rest and during peak dobutamine infusion (40 microg/kg/min). An abnormal response was defined as a decrease of less than 10% in LV end-diastolic volume, a decrease of less than 20% in end-systolic volume, and an increase of less than 10% in LV ejection fraction (EF) at peak dobutamine infusion, based on previously used criteria. The early/late diastolic flow (E/A) ratio and diastolic parameters were also measured. RESULTS: A blunted LV response to dobutamine was observed in 18 of 71 cirrhotic patients (25.4%). The baseline EF was significantly higher in 18 patients with a blunted DSE response than that of those with a normal DSE response (P<0.05). The baseline and peak E/A ratios, which are common diastolic dysfunction markers, were higher in the cirrhosis group than in the control group (P<0.001). No adverse events associated with DSE were observed. CONCLUSIONS: Blunted cardiac responses to dobutamine stimulation, which are implicated in defects in the beta-adrenergic signaling pathway, might contribute to the pathogenesis of CCM in patients with cirrhosis.

A Case of Miliary Tuberculosis Mimicking ARDS due to Bilateral Severe Pneumonia / 결핵및호흡기질환

Miliary tuberculosis is the most serious form of tuberculous disease, but is rarely complicated with acute respiratory distress syndrome (ARDS). When a patient with miliary tuberculosis initially presents with ARDS, the mortality is much higher. Therefore, the early detection of miliary tuberculosis as the underlying cause of ARDS is very important for the prognosis and survival of the patient. The diagnosis of miliary tuberculosis may be easy if the patient presents typical clinical manifestations associated with the characteristic pattern of miliary nodules on chest radiology. However, the diagnosis of miliary tuberculosis when complicated with ARDS can be difficult due to the nonspecific radiologic patterns, such as diffuse bilateral consolidation and ground glass opacity, without miliary nodular infiltration. However, these nonspecific patterns are known as less likely findings of miliary tuberculosis. We experienced a pregnant woman with miliary tuberculosis, mimicking ARDS due to bilateral severe pneumonia. She was admitted, via the emergency room, with sudden onset of fever, chill, cough and dyspnea. The initial chest PA and HRCT showed diffuse bilateral consolidation and ground glass opacity, without miliary nodular infiltration. All bacteriological studies, including blood and sputum cultures, tuberculosis-PCR and serologic study for infectious disease were negative. However, the definite diagnosis of unusual miliary tuberculosis as the underlying cause of ARDS was confirmed from the radiological finding and transbronchial fiberoptic lung biopsy. We report this case, with a review of the literature.

A Case of Licorice Induced Hypokalemic Paralysis with Rhabdomyolysis / 대한내분비학회지

Prolonged ingestion of licorice can cause hypermineralocorticoidism, with sodium retention, potassium loss and hypertension. Nevertheless, its initial presentation with a very severe degree of hypokalemic paralysis and rhabdomyolysis are exceedingly rare. We describe a patient who experienced hypokalemic paralysis and rhabdomyolysis after licorice ingestion. The patient's initial blood pressure was 160/80mmHg. The major biochemical abnormalities included; hypokalemia(K+ 1.3mEq/L), metabolic alkalosis, with a pH of 7.64, and urine myoglobin > 3000ng/mL. The plasma rennin activity and aldosterone level were suppressed. The 24 hour urine cortisol concentration was normal. The patients, over a 1 month period, had ingested 500g of licorice boiled in water. After quitting the licorice, the hypokalemia and muscle paralysis gradually improved and blood pressure returned to normal

Rupture of a Bleeding Pancreatic Pseudocyst into the Stomach: a Case Report / 대한소화기내시경학회지

Pancreatic pseudocyst is a well-known complication of pancreatitis. However spontaneous perforation and/or fistularization is rare. Perforations into the free peritoneal cavity, stomach, duodenum, colon, portal vein, pleural cavity, and through the abdominal wall have been reported. Rupture of pseudoaneurysm or bleeding pseudocyst following pancreatitis is a severe complication that can lead to massive gastrointestinal bleeding. Especially, rupture of a bleeding pseudocyst into the stomach combined with splenic artery pesudoaneurysm is very rare. We experienced a case of massive bleeding from pancreatic pseudocyst with pseudoaneurysmal rupture into the stomach which was controlled nonoperatively by splenic artery coil embolization and conservative treatment. We report the case with the literatures review.

A Case of Neuropsychiatric Lupus Presenting as Guillain-Barre Syndrome and Cerebral Infarction / 대한류마티스학회지

Systemic lupus erythematosus (SLE) is a disease of unknown etiology in which tissues and cells damaged by pathogenic autoantibodies and immune complexes. Nervous system involvement in patients with SLE encompasses a wide spectrum of neurologic and psychiatric features and the frequency of neuropsychiatric manifestations has been estimated at around 25% to 70%. American College of Rheumatology Ad Hoc Committee on neuropsychiatric lupus nomenclature developed case definitions for 19 different neuropsychiatric manifestations observed in SLE in 1999. Among them, Guillain-Barre syndrome and cerebral infarction are very rare neuropsychiatric manifestation. We experienced a 28-year-old woman with neuropsychiatric lupus which presented as Guillain-Barre syndrome and cerebral infarction. She was recovered after treatment with intravenous immunoglobulin, high dose methylprednisolone, cyclophosphamide and anticoagulants.

A Case of Primary Aortoduodenal Fistula / 대한소화기내시경학회지

Aortoenteric fistula is a rare and life-threatening cause of upper gastrointestinal hemorrhage. Fistulas may be classified as primary or secondary. Secondary aortoenteric fistulas usually occur at the suture line following arterial reconstruction with prosthetic material and developed in 0.5~2.4% of the patients. The incidence of primary fistulas was reported in 0.04~0.07% in a large autopsy series and is 0.69~2.36% in patients with abdominal aortic aneurysm. Atherosclerosis is now the dominant cause. The mortality rate of patients with primary aortoduodenal fistula (ADF) is extremely high, principally because the diagnosis is difficult and seldomly established before the massive bleeding results in emergency operation or death. This occurs predominantly in the third and fourth parts of the duodenum. Symptoms of ADF consist of flank pain or abdominal pain, hematemesis, melena, and an abdominal mass. ADF is curable, if diagnosed and treated with surgical intervention before the onset of lethal massive hemorrhage. We report a case of primary ADF with a review of the literatures.
