Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

We described the findings of fine needle aspiration cytology of the lung from a patient with Wegener's granulomatosis. Early diagnosis and prompt treatment of the patients with Wegener's granulomatosis is essential for a better prognosis. However, the variety of clinical presentations and nonspecific radiologic infiltrates of Wegener's granulomatosis frequently make the diagnosis difficult. Although an open lung biopsy is required for a firm diagnosis, fine needle aspiration cytology & biopsy preparation can also provide an adequate tissue sample, when the findings of fine needle aspiration are considered with clinical manifestations and ANCA value in the serum. The cytologic smears showed scattered necrotic tissue fragments entrapping many neutrophils and occasional epithelioid cells. Multinucleated giant cells were infrequently observed. Ziehl-Neelsen stain for acid fast bacilli was negative. All the cytologic features recapitulated the histopathologic findings of purulent and necrotizing granulomatous inflammation seen in Wegener's granulomatosis.

An ipsilateral supraclavicular lymph node recurrence of breast cancer after surgery has been considered a predecessor to distant metastases. There still is a debate as to whether breast carcinoma patients with the isolated supraclavicular lymph node recurrence should be considered to have disseminated disease or if aggressive treatment, with curative intent, is justified. We report two cases of an isolated ipsilateral supraclavicular lymph node recurrence following modified radical mastectomy, and multimodality treatments with modified radical neck dissection, systemic chemotherapy and involved field radiotherapy. These patients have lived without locoregional recurrence or distant metastases for 3 and 2 years, respectively. Conclusively, we recommend aggressive combined multimodality treatments, including surgery, such as modified radical neck dissection or complete excision of the involved lymph nodes, systemic chemotherapy, and involved field radiotherapy, in patients with isolated supraclavicular lymph node recurrence, but with no other evidence of distant metastases.

AHCC (Active Hexose Correlated Compounds), which was at first extracted from cultured broth of Basidiomycotina, is known to be one of the Biological Response Modifiers (BRM). We examined the protective effects of AHCC on carbon tetrachloride (CCl4) and thioacetamide (TAA)-induced liver injury in mice. The AHCC pretreatment prevented the suppression of several physiological and biochemical parameters in the mice injected with CCl4 or TAA for 5 days. The liver weights and serum ALT and AST levels were increased by CCl4 or TAA, the degree of which was significantly reduced with the AHCC pretreatment. The AHCC pretreatment induced increasing activity of GST (glutathione s-transferase) and showed an increasing tendency of P450 and EROD (ethoxyresorufin o-dealkylation). The AHCC pretreatment also showed negative effects against the suppression of drug metabolizing enzymes, such as P450, EROD, and GST induced by CCl4 or TAA. AHCC pretreatment showed protective effects with significant inhibition of fatty change, inflammation, and necrosis in CCl4 and TAA intoxicated mice liver. The present study suggests that the protective effect of AHCC pretreatment might be related to the protection of liver from the drug induced liver injury in mice model.

BACKGROUND: Plastic tubes have recently been used for blood collection tubes in clinical laboratories. The silicone coated plastic tube is said to be very similar with the glass tube and to show no difference with the glass tube in routine blood test except for some tests such as hormone tests and drug monitoring. So, we investigated the influence of plastic tube on the thyroid hormone test using two types of plastic vacuum tubes. METHODS: A total of 105 cases for the total triiodothyronine (T3), total thyroxine (T4), and thyroid stimulating hormone (TSH) were studied. The glass tube was a plain glass tube, and the plastic tube was a serum separator tube with gel. The plastic vacuum tubes used in this study were the SST II plus tube (Becton Dickinson, Franklin Lakes, USA) and the Vacuette tube (Greiner Bio-One, Kremsmunster, Austria). An IMMULITE 2000 analyzer (Diagnostic Products Corporation, Los Angeles, USA) was used to measure the total T3, total T4 and TSH. RESULTS: Comparisons of the measured values within 1 hour of blood collection in the plastic tube with that in the glass tube are as follows. There was no difference between the Vacuette tube and the glass tube for the three tests, while there was statistically significant difference between the SST II plus tube and the glass tube for the total T3 and total T4. CONCLUSIONS: It might need more cautious interpretation of the results by a solid-phase, competitive chemiluminescent enzyme immunoassay, when the plastic vacuum tube is used as a blood collection tube instead of the glass tube.

BACKGROUND: Sometimes we receive specimens collected several hours ahead, hemolyzed, or turbid. To decide to analyze the samples or not, the influence of storage time, hemolysis, and turbidi-ty on PT and PTT were studied. METHODS: Total of 198 cases for PT and 192 for aPTT were studied to clarify the effect of storage time on PT and aPTT. We performed the tests of PT and aPTT at 0, 2, 4, and 8 hours after collection of specimens. For the hemolysis effect study, we used 31 cases. Slightly, moderately, and severely hemolyzed plasma were obtained by adding hemolysate to plasma. For the turbidity effect study, we used 30 cases. Slightly, moderately, and severely turbid plasma were obtained by adding Intrali-pos (20% soybean oil) to plasma. RESULTS: Delayed test time affected the aPTT results after 8 hours. Hemolysis affected the PT and aPTT results. Turbidity did not affect the PT and aPTT results; however, the Coagrex-100s rejected to analyze the severely turbid samples. CONCLUSIONS: It is recommended that specimens be evaluated immediately or within 4 hours and that hemolysed or severely turbid specimens for PT and aPTT tests not be used.

OBJECTIVES: The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects. METHODS: Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups. RESULTS: In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI). CONCLUSIONS: The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.

BACKGROUND: Resistant organisms are now a growing and frequent problem in community-acquired infections. There is little information on the etiology and antimicrobial susceptibility patterns of community-acquired urinary tract infection (CA-UTI) at a tertiary-care hospital. METHODS: We evaluated the distribution of etiological organisms with their antimicrobial susceptibility patterns of CA-UTI in the patients visiting a tertiary-care hospital during the period of three years from 2001 through 2003. RESULTS: In total, 1,753 bacterial isolates yielded a significant growth as pathogens of CA-UTI in this study. The most common pathogen was Escherichia coli (38.3%), followed by Pseudomonas aeruginosa (10.8%), Enterococcus faecalis (7.3%), Klebsiella pneumoniae (6.4%), coagulase negative staphylococci (CoNS) (5.4%) and Staphylococcus aureus (5.2%). The prevalence of E. coli was significantly higher in females (P < 0.001), whereas P. aeruginosa, E. faecalis, and S. aureus were significantly more common in male group (P < 0.001). The susceptibility rate of E. coli was 26.0% to ampicillin, 65.8% to gentamicin, 51.3% to co-trimoxazole, and 62.5% to ciprofloxacin. The susceptibility patterns of Enterobacteriaceae other than E. coli were different from those of E. coli. Extended spectrum beta-lactamase was detected in 7.9% of E. coli and 15.6% of K. pneumoniae. CONCLUSION: This study demonstrates a diversity of etiological organisms and a high rate of resistance to commonly used antimicrobials of CA-UTI in patients visiting a tertiary-care hospital.

Amebic liver abscess (ALA) has been diagnosed in travelers to endemic areas or in patients with immunosuppression secondary to human immunodeficiency virus infection since the late 1990s. Further, it is a rare disease in Korea. ALA should be considered in patients present with fever and right upper quadrant pain along with a risk of exposure to amebiasis. We report an 82-year-old man with symptoms of fever, gross hematuria and severe renal impairment as having amebic liver abscess complicated with the obstruction of the inferior vena cava. Amebic liver abscess was successfully treated with antibiotics alone. Also, hematuria disappeared and renal dysfunction improved after treatment.
