Toxic shock syndrome (TSS) is a rare but life-threatening illness that is mainly caused by toxigenic strains of Staphylococcus aureus. Although TSS is classically known to be associated with tampon use, the number of TSS cases with non-menstrual causes such as skin and soft tissue infection has been increasing. Tattooing can result in several complications such as localized and systemic infections, inflammatory skin eruptions and neoplasms. We recently experienced a 26-year-old man diagnosed with typical TSS following tattooing. He complained of fever, chills and erythematous rash at tattoo site. Subsequently, the patient developed sign of shock. The skin cultures on the tattoo site were positive for methicillin-sensitive Staphylococcus aureus. The patient was successfully treated with vasopressor infusion and intravenous antibiotics and was discharged without complications. On discharge from the hospital 7 days later, desquamations on the tattoo site, fingers and toes were observed.

Purpose: Climate change has various negative effects on human health, which has resulted in increased burden on the health care system. Nurses contribute significantly to assessing climate-related health risks and creating a healthy environment. This study aimed to evaluate the reliability and validity of the Korean version of the Climate, Health, and Nursing Tool (K-CHANT) to measure nurses’ awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Methods: The 22 items of English CHANT were translated into Korean with forward-backward translation techniques. Internal consistency reliability, test-retest reliability, and construct validity using confirmatory factor analysis were performed using SPSS WIN (25.0) and AMOS (26.0). Survey data were collected from 220 master’s, doctoral, and post-doctoral nursing students. Results: The K-CHANT consists of 20 items across 5 domains.Two items of the original CHANT were excluded because of low content validity index and standardized regression weights. The internal consistency reliability of the K-CHANT, assessed by Cronbach’s αá was .81, with an intraclass correlation coefficient of .66~.90. The five subscales model was validated by confirmatory factor analysis (SRMR < .08, RMSEA < .08, AGFI > .70, CFI > .70). Conclusion The K-CHANT has satisfactory construct validity and reliability to measure nurses’ awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Future research should examine nurses’ perceptions and behaviors related to the health effects of climate change and develop an action plan to improve it.

PURPOSE: Although adjuvant chemotherapy reduces the risk of disease recurrence in stage III colon cancer patients, published guidelines do not specify when it should be initiated. This study aimed to assess the effect of adjuvant chemotherapy initiation time on disease recurrence and survival in stage III colon cancer patients undergoing curative surgical resection. METHODS: The medical records of stage III colon cancer patients undergoing curative resection between February 2004 and December 2009 were reviewed. RESULTS: Of the 133 enrolled patients, 27 (20.3%) began adjuvant chemotherapy within 3 weeks of surgery, whereas 106 (79.7%) did after 3 weeks following surgery. Patients receiving chemotherapy within 3 weeks of surgery were less likely to experience recurrences than those beginning treatment later (11.1% vs. 33%, P = 0.018). The mean disease-free survival of patients receiving adjuvant therapy earlier was 54.6 months, whereas that of patients with later treatment was 43.5 months (P = 0.014). However, no significant differences in overall survival were observed between the 2 groups. CONCLUSION: Adjuvant chemotherapy should be initiated as soon as a patient's clinical condition allows. Patients with stage III colon cancer may benefit from adjuvant chemotherapy initiated within 3 weeks of surgery.

PURPOSE: Dysbiosis of gut microbiota has been reported to participate in the pathogenesis of colorectal cancer, but changes in microbiota due to radiotherapy have not been studied. In this study, we tried to elucidate the changes in the microbiome in rectal cancer after chemoradiotherapy using RNA sequencing analysis.MATERIALS AND METHODS: We included 11 pairs of human rectal cancer tissues before and after irradiation between August 2016 and December 2017 and performed RNA sequencing analysis. Mapped reads to human reference genomes were used for pair-wise transcriptome comparisons, and unmapped (non-human) reads were then mapped to bacterial marker genes using PathSeq.RESULTS: At microbiome level, interindividual variability of mucosal microbiota was greater than the change in microbial composition during radiotherapy. This indicates that rapid homeostatic recovery of the mucosal microbial composition takes place short after radiotherapy. At single microbe level, Prevotella and Fusobacterium, which were identified as important causative microbes of the initiation and progression of rectal cancer were decreased by radiotherapy. Moreover, changes in Prevotella were associated with changes in the human transcriptome of rectal cancer. We also found that there was a gene cluster that increased and decreased in association with changes in microbial composition by chemoradiation.CONCLUSION: This study revealed changes in tumor-associated microbial community by irradiation in rectal cancer. These findings can be used to develop a new treatment strategy of neoadjuvant therapy for locally advanced rectal cancer by overcoming radio-resistance or facilitating radio-sensitivity.

This study examined infectious outcomes in elective colorectal cancer surgery between cefotetan alone or conventional triple antibiotics. From January to December 2007, 461 consecutive primary colorectal cancer patients underwent elective surgery. Group A contained 225 patients who received conventional triple antibiotics (cephalosporin, aminoglycoside and metronidazole) for prophylaxis, and group B contained 236 patients who received cefotetan alone for prophylaxis. Treatment failure was defined as the presence of postoperative infection including surgical-site infection (SSI), anastomotic leakage, and pneumonia or urinary tract infection. The two groups were similar in terms of demographics, American Society of Anesthesiologists (ASA) score, tumour location, stage, surgical approach (conventional open vs. laparoscopy-assisted), and type of operation. The treatment failure rates were 3.1% in Group A and 3.4% in Group B (absolute difference, -0.3%; 95% confidence interval [CI], 0.39 to 3.07, P=0.866), with SSI being the most common reason for failure in both groups (2.7% in Group A and 3.0% in Group B [absolute difference, -0.3%; 95% CI, 0.37 to 3.37, P=0.846]). Cefotetan alone is as effective as triple antibiotics for prophylaxis in primary colorectal cancer patients undergoing elective surgery.

Objective To investigate the clinical outcomes of an invasive strategy for elderly (aged≥75 years) patients with acute ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Methods Data on 366 of 409 elderly CS patients from a total of 6,132 acute STEMI cases enrolled in the Korea Acute Myocardial Infarction Registry between January 2008 and June 2011, were collected and analyzed. In-hospital deaths and the 1-month and 1-year survival rates free from major adverse cardiac events (MACE;defined as all cause death, myocardial infarction, and target vessel revascularization) were reported for the patients who had undergone invasive (n=310) and conservative (n=56) treatment strategies. Results The baseline clinical characteristics were not significantly different between the two groups. There were fewer in-hospital deaths in the invasive treatment strategy group (23.5%vs. 46.4%, P＜0.001). In addition, the 1-year MACE-free survival rate after invasive treatment was significantly lower compared with the conservative treatment (51%vs. 66%, P=0.001). Conclusions In elderly patients with acute STEMI complicated by CS, the outcomes of invasive strategy are similar to those in younger patients at the 1-year follow-up.

To classify the causes of hypogonadotropic hypogonadism in Korean patients, and to improve the endocrinologic evaluation for the disease, we retrospectively studied the clinical findings and result of combined pituitary stimulation test in 35 patients with hypogonadotropic hypogonadism. The following results were obtained.1) The ratio of male to female was 1.3:1, and the 50% of male patients was under 20 years of age and the 20% of female patients in 30th decades. 2) The chief complaints of male patients on the admission were the failure of secondary sexual characteristics(95.0%) and loss of hair(5.0%), those of female patients were amenorrhea(46.7%), infertility(26.7%), failure of secondary characteristics(13.3%) and loss of hair(13.3%). 3) The causes of male hypogonadotropic hypogonadism were craniopharyngioma(35.0%), idiopathic(30.0%), Kallmann's syndrome(15.0%), pituitary adenoma(10.0%) and germinoma(5.0%), and those of female hypogonadotropic hypogonadism were prolactinoma(13.3%), Sheehan's syndrome(26.6%), pituitary adenoma(6.7%), tuberculous granuloma(6.7%), germinoma(6.7%), idiopathic hypogonadotropic hypogonadism(40.0%).4) The responses of LH and FSH to GnRH test were absent or markedly blunted in diffuse pituitary diseases such as pituitary tuberculous granuloma, pituitary macroadenomas, Sheehan's syndrome. However those were also absent or blunted in Cushing's disease and hypothalamic disease such as Kallmann's syndrome, germinoma, craniopharyngioma, idiopathic hypogonadotropic hypogonadism. 5) The responses of LH, FSH increased after repeated injection of GnRH in a patient with germinoma. 6) In diffuse destructive pituitary diseases such as Sheehan's syndrome, nonfunctioning macroadenomas, tuberculous granuloma, large prolactinoma, the combined deficiency of pituitary hormones other than gonadotropins was observed. 7) In many cases with hypothalamic diseases, the combined defects of pituitary hormone response were also seen.These data suggest that GnRH test is not always useful to localize the lesion between pituitary and hypothalamus, and combined pituitary stimulation test revealed defects of pituitary hormones other than gonadotropin in various hypothalamic diseases.Therefore repeated GnRH test would be useful for the differential diagnosis, and CRH test and GRH test would be necessary to demonstrate whether pituitary abnormality is present.

PURPOSE: Leptin is encoded by the ob gene and is involved in the control of food intake and energy expenditure. Recent studies have implicated leptin expression to be an indicator of tumor features and prognosis. The purpose of this study was to investigate the association of tissue expression of leptin with the clinicopathological characteristics and clinical outcomes in colorectal cancer patients. METHODS: Patients who had undergone a curative surgical resection for a colorectal adenocarcinoma from 2000 to 2004 were included in the study. Immunohistochemical analyses of leptin expression were performed, and clinicopathological parameters were evaluated. RESULTS: Clinical data and tumor tissues of 146 patients were evaluated. The mean age was 68.6 +/- 11.3 years, and 61.0% were men. Immunohistochemically, the rates of negative, weak, moderate, and strong leptin expression were 2.7% (4 of 146), 5.5% (8 of 146), 43.2% (63 of 146), and 48.6% (71 of 146), respectively. We compared the negative, weak, and moderate expression group (group A) with the strong expression group (group B). Leptin expression was inversely associated with nodal stage (P = 0.007) between the two groups. Leptin expression was not significantly associated with differentiation (P = 0.37), T stage (P = 0.16), and American Joint Committee on Cancer stage (P = 0.49), and no significant differences in the disease-free and the overall survivals (P = 0.78 and P = 0.61) were observed. CONCLUSION: Results demonstrated an inverse association of nodal stage with high leptin expression. Higher leptin expression level might predict better oncologic outcome. However, further studies are warranted to identify the exact role of leptin expression in colorectal cancer.

The aim of this study was to investigate the relationship between somatostatinergic tone (SST) and the size of growth hormone (GH)-producing pituitary tumors. GH levels of 29 patients with newly diagnosed acromegaly were measured using a 75-gram oral glucose tolerance test (OGTT), an insulin tolerance test (ITT), and an octreotide suppression test (OST). Differences between GH levels during the ITT and the OGTT (DeltaGH(IO)), and between the OGTT and the OST at the same time point (DeltaGH(OS)) were compared according to the size of the tumor and the response pattern to the OST. DeltaGH(IO) of macroadenomas (n=22) was non-significantly higher than those of microadenomas while DeltaGH(OS) of macroadenomas were significantly higher than those of microadenomas. According to further analyses of macroadenomas based on the response pattern to the OST, GH levels during the ITT were significantly higher in non-responders. DeltaGH(OS) showed near-significant differences between responders and non-responders. In conclusion, as the size of the pituitary tumor increases, the effect of glucose on SST appears to be attenuated. Macroadenomas that are non-responders to the OST possess a portion of GH secretion exceeding the range of regulation by SST.
