Endovascular recanalization therapy for patients with acute ischemic stroke with hidden aortic dissection: A case series

Aortic dissection is one of the causes of acute ischemic stroke. Endovascular recanalization therapy (EVT) has emerged as an essential treatment for acute ischemic stroke due to large artery occlusion. However, it is rarely performed in the situation of hidden aortic dissection (AD). Two patients presented to the emergency room with focal neurologic deficits. The first patient was diagnosed with right internal carotid artery (ICA) occlusion. Angiography revealed that the ICA was occluded by the dissection flap. After a stent deployment in the proximal ICA, the antegrade flow was restored. The patient was diagnosed with AD on chest computed tomography (CT) after EVT. For the second patient, intraarterial thrombectomy was performed to treat left middle cerebral artery occlusion. AD was first detected on echocardiography, which was performed after EVT. Herein, we report successful endovascular recanalization therapy performed in two patients with acute ischemic stroke in the situation of undiagnosed aortic dissection. We also reviewed previous case reports and relevant literature.

FSP-1 expression in cancer cells is relevant to long-term oncological outcomes in nonmetastatic colorectal cancer

Purpose@#Recent studies have revealed that the expression of cancer-associated fibroblast (CAF) activation biomarkers in cancer cells is associated with clinical outcomes in patients with certain types of malignant tumors. However, whether the expression of CAF activation biomarkers affects the prognosis of colorectal cancer (CRC) has not been fully elucidated. This study aimed to evaluate the association between the expression of CAF activation biomarkers in cancer cells with cancer invasion and long-term oncological outcomes in patients with CRC. @*Methods@#Cancer specimens obtained from 135 patients with stage I–III CRC were examined using immunohistochemical staining to evaluate the expression of fibroblast specific protein-1 (FSP-1), fibroblast activation protein α (FAPα), α-smooth muscle actin (α-SMA), and vimentin in cancer cells. @*Results@#FSP-1 expression in cancer cells was significantly associated with lymphatic invasion, perineural invasion, tumor (T) status, and lymph node (N) status. FAPα expression in cancer cells was significantly associated with lymphatic invasion. On univariate and multivariate analyses, FSP-1 and α-SMA expression in cancer cells were associated with a short 10-year overall survival (OS) and high 10-year systemic recurrence (SR), respectively. Tumor budding was associated with a short 10-year OS. However, FAPα and vimentin did not contribute to the prognosis in this study. @*Conclusion@#In this study, we found that FSP-1 expression in cancer cells was related to cancer invasion. Additionally, FSP-1 and α-SMA expression in cancer cells was associated with 10-year OS and SR, respectively. Therefore, these markers may be used as predictors of long-term oncological outcomes in patients with CRC.

CMT1B Patient with a Novel p.Arg98Leu MPZ Variant Mimicking Chronic Inflammatory Demyelinating Polyneuropathy on Electrodiagnostic Testing

Conduction block or temporal dispersion on motor nerve conduction studies (NCSs) are known as key features of chronic inflammatory demyelinating polyneuropathy. Some types of CharcotMarieTooth disease (CMT) have been also reported to show conduction block or temporal dispersion on NCS. We experienced a case who presented with slowly progressive motor weakness, sensory loss, foot deformity, and segmental demyelination on NCS. We confirmed her and her mother harboring CMT1B with a novel p.Arg98Leu MPZ variant.

Multifunctional Indocyanine Green Applications for Fluorescence-Guided Laparoscopic Colorectal Surgery

Indocyanine green (ICG) could be applied for multiple functions such as fluorescent tumor localization, fluorescence lymph node mapping (FLNM), and intraoperative angiography in colorectal cancer surgery. With the near-infrared (NIR) systems, colonoscopic ICG tattooing can be used to define the early colorectal cancer that cannot be easily distinguished through the serosal surface. The lymphatic pathways can be visualized under the NIR system when ICG is injected through the submucosal or subserosal layer around the tumor. Intraoperative ICG angiography can be applied to find a favorable perfusion segment before the colon transection. Although all fluorescence functions are considered essential steps in image-guided surgery, it is difficult to perform multifunctional ICG applications in a single surgical procedure at once because complex protocols could interfere with each other. Therefore, we review the multifunctional ICG applications for fluorescent tumor localization, FLNM, and ICG angiography. We also discuss the optimal protocol for fluorescence-guided colorectal surgery.

Clinical effect and standardization of indocyanine green angiography in the laparoscopic colorectal surgery

Anastomotic complications occur after 5% to 20% of operations for rectosigmoid colon cancer. The intestinal perfusion status at the anastomotic site is an important modifiable risk factor, and surgeons should carefully evaluate and optimize the perfusion at the intended site of anastomosis. Indocyanine green (ICG) angiography is a simple noninvasive perfusion assessment modality. The use of ICG angiography is rapidly spreading in the field of colorectal surgery. However, there is debate on its contribution to reducing anastomotic complications. In this review, we discuss the clinical utility and the standardization of ICG angiography. ICG angiography can unequivocally reveal unfavorable perfusion zones and provide quantitative parameters to predict the risk of hypoperfusion-related anastomotic complications. Many studies have demonstrated the clinical utility of ICG angiography for reducing anastomotic complications. Recently, two multicenter randomized clinical trials reported that ICG angiography did not significantly reduce the incidence of anastomotic leakage. Most previous studies have been small-scale single-center studies, and there is no standardized ICG angiography protocol to date.Additionally, ICG angiography evaluations have mostly relied on surgeons’ subjective judgment. For these reasons, it is necessary to establish a standardized ICG angiography protocol and develop a quantitative analysis protocol for the objective assessment. In conclusion, ICG angiography could be useful for detecting poorly perfused colorectal segments to prevent anastomotic leakage after colorectal surgery. An optimized and standardized ICG angiography protocol should be established to improve the reliability of perfusion assessments. In the future, artificial intelligence-based quantitative analyses could be used to easily assess colonic perfusion status.

Is Laparoscopic Complete Mesocolic Excision and Central Vascular Ligation Really Necessary for All Patients With Right-Sided Colon Cancer?

Colon cancer treatment is on the way to evolution over several decades. The minimally invasive surgery has improved postoperative short-term outcomes. Adjuvant chemotherapy has prolonged the survival of advanced colon cancer patients. Hohenberger proposed the noble concept of complete mesocolic excision (CME) which consists of 3 components: plane surgery, sufficient longitudinal bowel resection, and central vascular ligation (CVL). Mesocolic plane surgery shares the same surgical principle of total mesorectal excision, which is maintaining the intact mesothelial envelope. However, there remain debates about the extent of bowel resection and the level of CVL for maximizing lymph node dissection. There is no solid clinical evidence for the oncological necessity and benefit of extended radical dissection in right hemicolectomy. CME with CVL based on open surgery has been adopted in laparoscopic surgery. So, it is also necessary to look at how the CME could be transformed and successfully implanted in the laparoscopic era. Recent rapid advances in surgical technology and cancer biology are preparing for fundamental changes in cancer surgery. In this study, we reviewed the history, oncological necessity, and compatibility of CME for the right hemicolectomy in the laparoscopic era and outline the new perspectives on the evolution of cancer surgery.

Compression injury of the circular stapler for gastrointestinal end-to-end anastomosis: preliminary in-vitro study

Purpose@#This preliminary in-vitro study was designed to evaluate the risk factors of compression injury from use of a circular stapler for end-to-end anastomosis. @*Methods@#Transparent collagen plates were prepared in dry and wet conditions. Physical properties of collagen plates and porcine colon tissue were examined using a rheometer. Adjustable and fixed-type circular staplers were applied on the collagen plates and the gap distance and compressive pressure were measured during anvil approximation. Tissue injury was evaluated using a compression injury scale. Compression properties were accessed to optimal or overcompression based on gap distance. @*Results@#Unacceptable injuries were rarely observed on the dry collagens, regardless of compression device. In the adjustable compression, the compressibility ratio was similar between dry and wet collagen. Overcompression and unacceptable injury increased on the wet collagens. In the fixed compression, the compressibility ratio increased significantly and unacceptable injuries were observed in more than 50% of wet collagens. Peak pressure was significantly higher in the fixed-compression types than those of adjustable type. On bivariate correlation analysis, fixed-compression type and wet collagens were respectively associated with overcompression. On multivariate analysis, edematous collagen condition was the most important risk factor and proximal anvil side, fixed compression type, and overcompression were also independent risk factors for unacceptable compression injury. @*Conclusion@#In the edematous tissue condition, unintentional overcompression could be increased and result in tissue injury on the compression line of the circular stapler.

Experience of taking Oral Contraceptives in Adult Women

PURPOSE: The purpose of this study was to explore essences and meanings of using oral contraceptives among adult women. METHODS: The interview was conducted with 20 adult women who lived in Seoul, Gyeongi Province, Jeolla Province, Chungcheong Province, and Gangwon Province. Participants with the experience of using oral contraceptives for contraception were selected by convenience sampling. Semi-structured interviews were conducted for data collection. The data were analyzed using Colaizzi's method. RESULTS: Five themes revealed: ‘Lack of information and knowledge regarding oral contraceptives’, ‘Inconvenient and difficult purchase process of oral contraceptives’, ‘Pressure and fear regarding other people's reaction’, ‘Self-centered thinking toward the use of oral contraceptives’, ‘A need for a change in public awareness and policy’. CONCLUSION: A change in society's perception about oral contraceptives is required for safe contraceptives use. Therefore, it is necessary to educate the correct usage of oral contraceptives, and to develop a program for changing the paradigm of sex education.

Predictors of job satisfaction and burnout among tuberculosis management nurses and physicians / 한국역학회지

OBJECTIVES: This study examined job satisfaction, empowerment, job stress, and burnout among tuberculosis management nurses and physicians in public healthcare institutions. METHODS: This was a cross-sectional study analyzing survey data collected from 249 nurses and 57 physicians in 105 public health centers, three public tuberculosis hospitals, and one tertiary hospital. The survey questionnaire comprised general characteristics, work-related characteristics, and four index scales (job satisfaction, empowerment, job stress, and burnout). The two-sample t-test was used to estimate the mean differences in the four index scales. Multiple regression analysis was used to determine whether general and work-related characteristics affected the four index scales. RESULTS: The job satisfaction and empowerment scores of the nurses were lower than those of the physicians. Except for the tuberculosis-specialized hospitals alone, the average job satisfaction scores of nurses were higher than those of physicians. Moreover, the nurses reported more job stress and burnout than did the physicians in tuberculosis departments in public healthcare institutions in Korea; in particular, the burnout reported by nurses was significantly higher than that reported by physicians at the National Medical Center. Marital status, nursing position, number of coworkers, the average number of days of overtime work per month, self-rated health, and hospital type were associated with the four index scales. CONCLUSIONS: Overall, nurses were more vulnerable to job stress and burnout than physicians. Reducing the workload of nurses by ensuring the presence of sufficient nursing staff and equipment, as well as by equipping facilities to prevent tuberculosis infections, should be considered priorities.

Health Status and Health Service Utilization: Barriers and Facilitators for Korea Medicaid Beneficiaries

PURPOSE: This study compares beneficiaries of Korean Medicaid with those under the National Health Insurance program, seeking to understand how each group utilizes their healthcare. METHODS: Data were obtained from a Health Promotion Survey in 2005. Health status was measured by the respondents' perception of health. Health service utilization included the availability of healthcare services, the type of healthcare institution, and intent to revisit. Predisposing and enabling factors, as well as health care needs were used for this study. RESULTS: Compared to National Health Insurance beneficiaries, Medicaid beneficiaries reported lower levels of health status and fewer enabling factors. They had more chronic diseases and disabilities. Education level, existence of chronic diseases, exercise patterns, and disabilities were associated with health status. CONCLUSION: We found that Medicaid beneficiaries had fewer resources and higher levels of health needs. As Medicaid is reformed, policy makers and administrators should understand healthcare utilization behaviors of Medicaid beneficiaries and the factors hindering access to care.

Implementation and Results of a Survey on Safe Community Programs in Gangbuk-gu, Korea: Focusing on Participants at a Local Public Health Center / 예방의학회지

OBJECTIVES: The purpose of this study was to investigate the current status of and problems with the Safe Community Programs in Gangbuk-gu, one of the 25 districts of the capital city of Korea. METHODS: The study subjects were 396 individuals who were involved in Safe Community Programs between 2009 and 2011. We examined the effectiveness and willingness of respondents to participate as a safety leader of the Safe Community Program with a questionnaire. We examined the injury death rates of Gangbuk-gu by using of the death certificate data of Korea's National Statistical Office. Descriptive statistics and chi-squared tests were used. RESULTS: The effectiveness of programs did not differ but active participation differed significantly among subjects (p<0.05). The injury death rate of Gangbuk-gu as a whole increased during the implementation period. However, senior safety, in particular, may be a helpful program for reducing injuries in Gangbuk-gu. CONCLUSIONS: This study suggests that the lack of active participation may be a major problem of Safe Community Programs in Gangbuk-gu. Therefore, Safe Community Programs should be expanded to the entire district of Gangbuk-gu and more active participation programs should be developed.

Comparison of Neurite Outgrowth Induced by Erythropoietin (EPO) and Carbamylated Erythropoietin (CEPO) in Hippocampal Neural Progenitor Cells

A previous animal study has shown the effects of erythropoietin (EPO) and its non-erythropoietic carbamylated derivative (CEPO) on neurogenesis in the dentate gyrus. In the present study, we sought to investigate the effect of EPO on adult hippocampal neurogenesis, and to compare the ability of EPO and CEPO promoting dendrite elongation in cultured hippocampal neural progenitor cells. Two-month-old male BALB/c mice were given daily injections of EPO (5 U/g) for seven days and were sacrificed 12 hours after the final injection. Proliferation assays demonstrated that EPO treatment increased the density of bromodeoxyuridine (BrdU)-labeled cells in the subgranular zone (SGZ) compared to that in vehicle-treated controls. Functional differentiation studies using dissociated hippocampal cultures revealed that EPO treatment also increased the number of double-labeled BrdU/microtubule-associated protein 2 (MAP2) neurons compared to those in vehicle-treated controls. Both EPO and CEPO treatment significantly increased the length of neurites and spine density in MAP2(+) cells. In summary, these results provide evidences that EPO and CEPO promote adult hippocampal neurogenesis and neuronal differentiation. These suggest that EPO and CEPO could be a good candidate for treating neuropsychiatric disorders such as depression and anxiety associated with neuronal atrophy and reduced hippocampal neurogenesis.

Prehospital Delay Factors After Stroke and Paramedic Identification of Stroke Patients in a Metropolitan City Emergency Medical Service System

BACKGROUND: Accurate recognition of stroke victims by ambulance paramedics is necessary to ensure the rapid transfer of these patients to the hospital. We carried out a prospective study to characterize the cause of prehospital delays after stroke by the emergency medical service (EMS) and to determine the accuracy of identifying acute stroke by paramedics. METHODS: All paramedics in the Busan Metropolitan 119 EMS were asked to record the clinical presentations and time intervals from symptom onset to various points along the patients' prehospital course on the ambulance admission sheets for suspected stroke patients during a month (February 1, 2010 to February 28, 2010). Neurologists in twenty four hospitals reviewed the hospital records for the patients who were given a diagnosis of stroke or transient ischemic attack by the paramedics. RESULTS: Of the EMS on-scene evaluations, the diagnosis of stroke by ambulance paramedics was correct for 79 of the 186 (43%) patients. Positive predictive values for main suspected stroke symptoms were 95% in hemiparesis, 88% in speech disturbance and 44% in impaired consciousness. The prehospital personnel transferred the suspected stroke patients to each hospital at a mean of 25 minutes after the emergency 119 call. However, only 62% of the stroke patients called EMS within the first 2 hours of stroke. CONCLUSIONS: Public education for the need to seek EMS promptly after stroke as a medical emergency, and strokespecific training for EMS personnel are essential so that stroke patients receive effective acute treatment.

Protective Effect of Kefir Grain Against Dextran Sodium Sulfate-Induced Colitis in Rats

Probiotics have emerged as a potential treatment modality for numerous gastrointestinal disorders, including IBD. However, few probiotics have undergone appropriate preclinical screening in vivo. Kefir is considered a probiotic, benefiting the host through its effects in the intestinal tract. Despite numerous studies examining the action of probiotics on the host organism, few have analyzed the effects on intestinal environment. We assessed the protective effect of kefir for three weeks before inducing colitis with 2% dextran sodium sulfate for five days. The DSS loads were similar in all DSS treatment group. The results of the experiment are as follows. Food intake and FER of experimental groups were not significantly different each other, but water consumption tended to be higher in all DSS treatment groups as compared with the normal control. And visual inspection of feces revealed mild diarrhea in rat given 2% DSS. The anti-inflammatory activity of kefir was determined by myeloperoxidase activity during the DSS treatment, and there was no significant difference in any group. The levels of thiobarbituric acid reactive substances (TBARS) as a colonic lipid peroxidation were significantly lower in the kefir intake groups than in rats treated with 2% DSS alone. The DNA % in tail and tail moment values as a DNA damage level of the blood lymphocytes in kefir intake groups tended to be lower than 2% DSS treatment alone, especially tail lengths were significantly diminished. According to the colonic histopathological assay, there were a severe inflammation of lamina propria and submucosa and mild edema in mucosa and sub mucosa in DSS alone treated group. We found a slight regenerative change in kefir treatment groups. In our experiments, this means that ulcerative colitis related to oxidative injury might be prevented by kefir as a probiotic. Further studies of the potential benefits of kefir as a probiotic in inflammatory condition are encouraged.

Cockroach Allergic Rhinitis in the Urban Area in Korea: Sensitivity and Diagnosis / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Recently persistent type and mixed sensitization of allergic rhinitis are on the rise. We have frequently experienced patients sensitized to cockroach in allergic skin test (AST). There was a report that cockroach was prevalent in each house within Seoul metropolitan area. The aim of this study is to investigate the prevalence of patients sensitized to cockroach and to compare AST positivity to cockroach with multiple allergosorbent chemiluminescent assay (MAST-CLA) result. SUBJECTIVES AND METHOD: Allergic skin test with 5 common inhalant allergens was performed in 180 patients who had visited Allergic Clinic of Kyung-Hee University Hospital from Jan. 2003 to Jul. 2003. Among them, MAST-CLA was performed in 54 patients who tested positive to cockroach on allergic skin test. Western blot analysis was performed in 10 cockroach sensitized patients with negative result in MAST. RESULTS: 54 patients (30%) were AST positive to cockroach among 180 patients had allergic rhinitis. Concomitant offending antigen were D. farinae (63%), House dust (33.3%), Candida (13%), Aspergillus (9.3%). There was discrepancy between the result of AST and MAST. Only 13.6% patients who showed positive AST revealed positivity on MAST. Minor bands of cockroach antigen in Western blot were detected in 6 of 10 patients who were sensitized to cockroach in AST but not to MAST. CONCLUSION: We suggest that cockroach should be considered as an important antigen in allergic rhinitis. It should be needed for the diagnosis of cockroach allergic rhinitis that MAST sensitivity is increased.

Postoperative Results of Canal Wall Up Mastoidectomy Only Performing Anterior Tympanotomy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Retrospective reflect of canal wall up (CWU) mastoidectomy with posterior tympanotomy revealed some problems such as ineffectiveness against the recurrence of cholesteatoma, reclosure of ventilation route and that a posterior tympanotomy might be harmful to inner ear. Objectives of this study is to evaluate the effect of mastoidectomy with anterior tympanotomy on postoperative hearing results and complications. SUBJECTS AND METHOD: From January 1998 through July 2001, 29 cases of CWU mastoidectomy with anterior tympanotomy were reviewed retrospectively. All of the cases were difficult to perform posterior tympanotomy due to anatomical variations and had lesions restricted to anterior epitympanum. The hearing results were assessed by postoperative 1-year pure tone average and postoperative 1-year air-bone gap (ABG), and we checked complications. RESULTS: Of the 29 cases, 21 cases (72.4%) had ABG <20 dB in the postoperative 1-year, with the postoperative 1-year ABG of 14.9+/-9.2 dB. The postoperative hearing gain was 10.1+/-10.6 dB. There were 3 cases of chorda tympani nerve cutting, 1 case of accidental malleoincudal joint dislocation and 1 case of recurrence. CONCLUSION: Anterior tympanotomy could be a good approach for ventilation in selected CWU mastoidectomy approach, and further long term follow-up is needed to study about recurrence.

The Application of the Satisfaction with Amplification in Daily Life Scale in Hearing Aid Users / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The evaluation of subjective satisfaction by hearing aid users is important in view of improving pre-assessment needs and predicting treatment outcome. We evaluated the subjective satisfaction by hearing aid users accodin to the Satisfaction with Amplification in Daily Life (SADL) scale, which emphasizes nonauditory factors contributing to satisfaction as well as benefit. SUBJECTS AND METHOD: The SADL scale was completed by 42 patients who received hearing aid fitting at Kyung Hee University Hospital from October 2002 to April 2003 ; each 4 subscales of the SADL were evaluated according to the type and degree of hearing loss, the pure tone audiogram pattern and shape and type of the hearing aid. RESULTS: The mixed type hearing loss group showed higher satisfaction than the sensorineural hearing loss group with respect to positive effect and personal image. Mild and moderate hearing loss groups showed a higher overall satisfaction than severe hearing loss group. There were no statistical differences of scores between pure tone audiogram patterns, and shapes and types of hearing aids, but female users showed higher personal image score when using small (ITC, CIC) hearing aids than large (BTE, ITE) ones. Ascending, descending, and peak type pure tone audiogram patterns users showed a higher satisfaction in positive effect and service and cost when using digital hearing aids than analogue ones. CONCLUSION: Satisfaction is affected by different variables that could be measured by the SADL scales that evaluate independent domains. Assessing patient's subjective satisfaction can be helpful in planning appropriate intervention.
