PURPOSE: We report a case of candidal endophthlmitis developed in a patient with advanced gastric cancer who recently injured by flame burn. He was treated successfully with intravitreous and intravenous antifungal agents. METHODS: A 40-year-old man visited with complaints of decreased binocular visual acuity 7 weeks after third degree flame burn injury to 25% of body surface. Indirect ophthalmoscope showed findings of fungal endophthalmitis and upper gastro-intestinal endoscopic examination diagnosed of fungal esophagitis and advanced gastric cancer. He was treated with amphotericin B intranvitreously and fluconazole and amphotericin B intravenously. RESULTS: His visual acuity was improved to 20/50 (OD), 20/30 (OS) following 4 weeks after treatment and intraocular inflammation was decreased. After 5 months, he recovered his visual acuity as 20/25 (OD), 20/20 (OS), and had no inflammation in anterior chamber and vitreous.

Klebsiella pneumoniae has been reported to be the most common pathogen causing pyogenic liver abscess. K. pneumoniae liver abscess occurs fairly often in patients with diabetes mellitus, and is commonly associated with metastatic infections such as brain abscess, endophthalmitis, lung abscess, osteomyelitis, prostatitis, necrotizing fasciitis and infection in other sites. Although septic pulmonary embolism (SPE) is uncommon, it is a serious metastatic complication of K. pneumoniae liver abscess. Chest computed tomography (CT) scans are crucial in making the early diagnosis of SPE; however, it does not provide the basis for a definitive diagnosis. A 70-year-old man was referred to the Department of Pulmonology due to cough and an abnormal chest radiography. The chest CT scans revealed relatively well-demarcated, round multiple nodules with peripheral preponderance, cavitary mass in the right upper lobe of the lung and low-density hepatic cystic masses. Bronchoscopic examination and percutaneous needle aspiration of the lung were performed, but there was no evidence of malignancy. Finally, K. pneumoniae was grown from a bronchial washing specimen and blood culture. Intravenous carbapenem was administered over a 3-week period and follow-up CT scans showed improvement in both the lung and the liver. We report a case of K. pneumoniae liver abscess complicated with SPE requiring differential diagnosis of hematogenous metastatic malignancy on CT scans in an elderly patient.

Pseudochylothorax is an uncommon pleural effusion disease characterized by the presence of cholesterol crystals or high lipid content not resulting from a disrupted thoracic duct. Most of the cases reported so far had been found in patients with long-standing pleural effusion due to a chronic inflammatory disease such as old tuberculous pleurisy or chronic rheumatoid pleurisy. Authors encountered a case of pseudochylothorax in a 45-year-old man who had been treated for tuberculous pleurisy 6 years before his visit to authors' hospital. After that, he had visited the emergency department many times for removal of pleural effusion. The patient's chest X-ray revealed dyspnea and large left-sided pleural effusion. Although a large amount of pleural fluid was removed with a drainage catheter, massive pleural effusion was likely to recur, and the underlying lung was able to fully re-expand. Accordingly, decortication was done, and the patient's symptom was improved without postoperative complications.

Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy, is caused by emotional or physical stressors and mimics acute myocardial infarction. Stress-induced cardiomyopathy is characterized by acute, reversible left ventricular apical ballooning without significant coronary artery stenosis. New variants of stress-induced cardiomyo pathy with localized wall motion abnormalities or an inverted pattern with a hyperdynamic apex have been reported. We present a rare case of a sudden cardiac arrest due to atypical stress-induced cardiomyopathy (mucosal packing and the injection of epinephrine) in an elderly male patient during elective endoscopic sinus surgery with septoplasty under local anesthesia. In this case, only the basal and midportions of the left ventricle were affected, whereas the apex was completely spared. The patient rapidly and completely recovered without sequelae.

BACKGROUND: Complementary and alternative medicine (CAM) is now being increasingly used among cancer patients. The objectives of our study were to assess the prevalence, types, cost, subjective effects, and side effects of CAM use, reasons for CAM use, characteristics of CAM users compared to those of nonusers, and patients' expectations of doctors regarding their CAM use among Korean cancer patients at a single cancer center. METHODS: From April to August, 2003, we interviewed 186 cancer patients hospitalized in the Korea Cancer Center Hospital using a structured questionnaire, and analyzed the data. RESULTS: 78.5% of experimental subjects (146 patients) had been treated with at least one type of CAM, in addition to conventional Western treatment, with a mean monthly cost of 1, 380, 000 Won/person (approximately, 1, 100 U.S. dollars on July, 2004). The most prevalent types of CAM used by these patients included medicinal mushrooms (67.1%), herbs (54.1%), vegetable diets (50.6%), and ginseng (46.5%). The main reported reasons for the use of CAM in addition to conventional medicine were nutritional support (19.1%) and physical strengthening (17.8%). 5% of CAM users experienced side effects. The younger and more educated the patients were, the more likely they were to employ CAM. 66% of CAM users wanted to discuss CAM techniques with their doctors. CONCLUSION: More than two-thirds of cancer patients used various kinds of CAM, incurring considerable costs. Therefore, in order to help patients make informed decisions, medical society should be open to communication with patients. Not only the scientific aspects, but also the economic aspects of CAM usage should be examined more thoroughly, in order to ensure proper distribution of medical resources.

The molecular mechanism underlying the initiation of somatic cell reprogramming into induced pluripotent stem cells (iPSCs) has not been well described. Thus, we generated single-cell-derived clones by using a combination of drug-inducible vectors encoding transcription factors (Oct4, Sox2, Klf4 and Myc) and a single-cell expansion strategy. This system achieved a high reprogramming efficiency after metabolic and epigenetic remodeling. Functional analyses of the cloned cells revealed that extracellular signal-regulated kinase (ERK) signaling was downregulated at an early stage of reprogramming and that its inhibition was a driving force for iPSC formation. Among the reprogramming factors, Myc predominantly induced ERK suppression. ERK inhibition upregulated the conversion of somatic cells into iPSCs through concomitant suppression of serum response factor (SRF). Conversely, SRF activation suppressed the reprogramming induced by ERK inhibition and negatively regulated embryonic pluripotency by inducing differentiation via upregulation of immediate early genes, such as c-Jun, c-Fos and EGR1. These data reveal that suppression of the ERK-SRF axis is an initial molecular event that facilitates iPSC formation and may be a useful surrogate marker for cellular reprogramming.
