Flash pulmonary edema is characterized by a sudden episode of dyspnea resulting from acute pulmonary venous congestion, which resolves rapidly. We report a case of renal artery stenosis presenting as flash pulmonary edema in a patient with solitary kidney treated by angioplasty with stent implantation. A 75-year-old man with solitary kidney visited the emergency room with acute shortness of breath. His blood pressure had risen to 206/90 mmHg and a chest radiograph revealed pulmonary edema. Echocardiography and coronary arteriography showed no clear abnormalities, but abdominal computed tomography revealed severe focal stenosis in the left proximal renal artery. A captopril renal scan found that the time to peak and half-time of radioactivity were delayed in the left kidney. Percutaneous transluminal angioplasty was performed, followed by stent implantation. After this procedure, the stenotic segment was completely dilated and blood pressure returned to the normal range.

BACKGROUND/AIMS: Transarterial chemoembolization (TACE) is performed for single hepatocellular carcinoma (HCC) that are not eligible for surgery or ablation therapy. We investigated the clinical outcomes of patients with a single HCC ≤ 5 cm treated with TACE. METHODS: This study analyzed 175 consecutive patients who underwent TACE as an initial treatment for single HCC ≤ 5 cm. Predictive factors for complete response (CR), recurrence after CR, and overall survival (OS) were evaluated. RESULTS: Total 119 patients (68%) achieved CR after TACE. Tumor size < 3 cm and hepatitis B virus infection were significant predictors of CR (p < 0.05). Recurrent HCC was detected in 73 patients (61.3%) after CR. Age > 65 years and absence of liver cirrhosis were predictive factors for non-recurrence after CR (p < 0.05). The OS for all patients was 80.7 ± 5.6 months, and the 1-, 3-, and 5-year OS rates were 88.1%, 64.8%, and 49.9%, respectively. In multivariate analysis for OS, CR (hazard ratio [HR], 0.467; 95% confidence interval [CI], 0.292 to 0.747) and Child class A (HR, 0.390; 95% CI, 0.243 to 0.626) were significant factors. The OS for the CR and Child class A group were 92 and 93.6 months, respectively, and that of the non-CR and Child B, C group were 53.3 and 50.7 months, respectively (p < 0.001). CONCLUSIONS TACE can be a valid treatment in patients with a single HCC ≤ 5 cm not suitable for curative treatment, especially in patients with Child class A and CR after TACE.

BACKGROUND/AIMS: To investigate the predictive factors for complete response (CR) and recurrence after CR in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). METHODS: Among 691 newly diagnosed HCC patients, 287 were treated with TACE as a first therapy. We analyzed the predictive factors for CR, recurrence after CR, and overall survival (OS). RESULTS: Eighty-one patients (28.2%) achieved CR after TACE, and recurrence after CR was detected in 35 patients (43.2%). In multivariate analyses, tumor size (≤5 cm) and single nodularity were predictive factors for CR, with hazard ratios (HRs) of 0.35 (p=0.002) and 0.41 (p<0.001), respectively. Elevated serum α-fetoprotein (AFP) (>20 ng/mL) level and multinodularity exhibited significant relationships with recurrence after CR, with HRs of 2.220 (p=0.026) and 3.887 (p<0.001), respectively. Tumor size (>5 cm), multinodularity, elevated serum AFP (>20 ng/mL) level, Child-Turcotte-Pugh score (B and C), and portal vein thrombosis were significant factors for OS. CONCLUSIONS: In patients treated with TACE as a first therapy, tumor size (≤5 cm) and single nodularity were predictive factors for CR, and multinodularity and elevated serum AFP (>20 ng/mL) levels were predictive factors for recurrence after CR. These factors were also significant for OS.

Emphysematous pyelonephritis (EPN) is a severe gas-forming infection of the renal parenchyma and surrounding tissues. Patients with EPN commonly present with high fever, chills, and flank pain. These symptoms mimic a simple urinary tract infection, such that diagnosis is often delayed. Because of its life-threatening fulminant course, the early detection of EPN and its prompt treatment with intravenous antibiotics with or without percutaneous drainage are critical. Here we describe a case of a 63-year-old Korean female with diabetes mellitus who had no specific symptoms or signs of EPN. A chest computed tomography (CT) scan to assess a right pleural effusion incidentally detected an abnormal gas shadow in the renal parenchyma. An abdominal CT scan performed 5 days later showed increased gas within the kidney parenchyma, but the patient still had no symptoms of EPN. She was treated with intravenous antibiotics alone. A follow-up abdominal CT scan revealed the complete disappearance of the features of EPN.

OBJECTIVE: Pain is very common in the elderly, so there is a high prevalence of analgesic use among this population. The purpose of this study was to assess patterns of analgesic use and evaluate factors associated with analgesic use in elderly patients. METHOD: The subjects of this study were patients over 65 years old hospitalized in a teaching hospital located in Chuncheon-si, Korea between January 1, 2014 and March 31, 2014. Data collection regarding analgesic prescriptions and baseline characteristics was conducted using computerized hospital database by medical information team. Logistic regression analysis was used to identify factors related to analgesic use. RESULTS: A total of 2,394 patients were finally included. Among these patients, 700 (29.2%) took analgesics; 521 (74.4%) out of these 700 patients were received opioid analgesics and 179 (25.6%) were received only non-opioid analgesics. The most frequently prescribed opioid analgesic was pethidine (45.7%), and the most frequently prescribed non-opioid analgesic was acetaminophen (44.1%). Fracture was associated with increased odds of opioid analgesic prescriptions (OR = 2.766, 95% CI = 2.019-3.790, p < 0.001) and any analgesic prescriptions (OR = 2.394, 95% CI = 1.766-3.244, p < 0.001). Stroke or cerebral infarction was associated with decreased odds of opioid analgesic prescriptions (OR = 0.636, 95% CI = 0.471-0.858, p = 0.003). CONCLUSION: A significant proportion of hospitalized elderly patients use analgesics. Health care professionals should consider factors associated with analgesic use in this population to improve pain management.

BACKGROUND: Therapeutic plasma exchange (TPE) is an effective and practical treatment for separation and removal of harmful antibodies or pathogenic substances from the blood. The volume of plasma removed must be replaced by a replacement fluid such as 4~5% albumin solution or Fresh frozen plasma (FFP). We conducted a study of coagulopathy using albumin solution and checked the chemical composition of fresh frozen plasma. METHODS: We measured pre- and post-TPE PT/aPTT for evaluation of the effect of albumin replacement on coagulation from 192 TPE sessions of 19 patients. We also investigated routine chemistry test items including glucose and electrolytes from 10 randomly selected FFP. RESULTS: The post PT and aPTT within four hours after TPE were prolonged due to a transient decrease in coagulation factors, but were normalized within 2 days after TPE. All coagulation time was corrected to the level of the pre-TPE status within four hours before the next TPE except the patients who received TPE 6 times or more. FFP showed higher level in glucose, sodium and inorganic phosphate. CONCLUSION: Albumin exchange produces temporary coagulation factor deficiency. However, this transient factor deficiency rarely causes clinical problems and the factors are rapidly corrected by redistribution and resynthesis. We should be careful about hypocalcemia, hyperglycemia, and hypernatremia when using FFP replacement.

Tacrolimus and cyclosporine have been used in various formulations, but their hypersensitivity reactions are rare in practice. Castor oil derivatives are nonionic surfactants used in aqueous preparations of hydrophobic active pharmaceutical ingredients. Castor oil derivatives that can be used as additives to tacrolimus and cyclosporine may play a role in the development of hypersensitivity reactions, especially anaphylaxis. Various immunologic and nonimmunologic mechanisms have been implicated in hypersensitivity reactions induced by castor oil derivatives. Physicians should be aware that not only the drug itself, but also its additives or metabolites could induce hypersensitivity reactions. We report a case of anaphylaxis caused by vitamin K (phytonadine), serotonin antagonist (granisetron), intravenous tacrolimus, and cyclosporine. Interestingly, the patient tolerated oral cyclosporine, which did not contain Cremophor EL or polysorbate 80.

While esophagogastric varices are common manifestations of portal hypertension, variceal bleeding from the jejunum is a rare complication of liver cirrhosis. In addition, ectopic variceal bleeding occurs in the duodenum and at sites of previous bowel surgery in most cases, including of stomas. We report a case of obscure overt gastrointestinal bleeding from jejunal varices in a 55-year-old woman who had not previously undergone abdominal surgery, who had liver cirrhosis induced by the hepatitis C virus. Emergency endoscopy revealed the presence of esophageal varices without stigmata of recent bleeding, and no bleeding focus was found at colonoscopy. She continued to produce recurrent melena with hematochezia and received up to 21 units of packed red blood cells. CT angiography revealed the presence of jejunal varices, but no active bleeding was found. Capsule endoscopy revealed fresh blood in the jejunum. The patient submitted to embolization of the jejunal varices via the portal vein, after which she had a stable hemoglobin level and no recurrence of the melena. This is a case of variceal bleeding from the jejunum in a liver cirrhosis patient without a prior history of abdominal surgery.

BACKGROUND: This study was performed to find the optimal volume of local anesthetics needed for a successful ultrasound-guided stellate ganglion block (SGB) to treat head and neck pathology. METHODS: Fifteen female and fourteen male sensory-neural hearing loss patients received 4 times SGBs with 0.2% ropivacaine in volumes of 6, 4, 3 and 2 ml at 1 to 3 day intervals. Using the transverse short-axis view of the neck that showed Chassaignac's tubercle at the C6 level, a 25-gauge, and 4 cm needle was inserted via the lateral paracarotid approach with out-of-plane targeting between the prevertebral fascia and the ventral surface of longus colli muscle (subfascial injection). A successful block was confirmed with the onset of ptosis (Horner's syndrome). RESULTS: There were no significant statistical differences between the presence of Horner's syndrome and the volume of local anesthetics given. However, Horner's syndrome was present in all trials for the 4 ml and 6 ml groups. Six (20.7%) and three out (10.4%) of twenty-nine trials in the 2 ml and 3 ml groups, respectively, failed to elicit Horner's syndrome. The duration of action was significantly different in the 2 ml group compared to that of the 6 ml group, but there was no significant difference between the other groups, including the 4 ml vs. 6 ml groups. The side effects were not different between the groups. CONCLUSIONS: This data suggests that the optimal volume of 0.2% ropivacaine for ultrasound-guided SGB to treat the head and neck pathology in daily practice is 4 ml.

Idiopathic peripartum cardiomyopathy is an uncommon malady disease. Making the diagnosis is often difficult and it is always necessary to exclude other prior heart disease and other causes of left ventricular dysfunction in pregnant women. Heart failure in these women ensues when the cardiovascular demands of normal pregnancy are further amplified when the common complications of pregnancy complications superimposed upon these underlying conditions that cause compensated ventricular hypertrophy. This may be aggravated by making a late diagnosis and providing inappropriate treatment. We experienced a 38-year-primigravida who has diagnosed with idiopathic peripartum cardiomyopathy and underwent elective cesarean section with general anesthesia.
