ABSTRACT

PURPOSE: This study aimed to explore influencing factors on care burden among family caregivers for elders with dementia living at home. METHODS: Participants in this study were 211 family caregivers who were taking care of elders registered at a support center for dementia located in S-gu, Seoul. Data were collected using a structured questionnaire. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression in SPSS WIN 23.0. RESULTS: The care burden of family caregivers was mild to moderate (40.31±21.50) in this study. The factors influencing care burden among family caregivers for elders with dementia were the age, behavioral problems, and dependency in instrumental activities of daily living of demented elderly, in addition to the perceived health status and resting hours of family caregivers. Overall, these factors explained 46.5% of the total variability in care burden in this sample (F=13.01, p < .001). CONCLUSION: Findings from this study suggest that the characteristics of demented elderly and family caregivers can influence care burden differently. Individually tailored strategies based on the various caregiving contexts need to be developed to reduce the level of care burden among family caregivers for elders with dementia.

ABSTRACT

BACKGROUND: Glenoid baseplate location is important to good clinical outcomes of reverse total shoulder arthroplasty (RTSA). The glenoid vault is the determining factor for glenoid baseplate location, but, to date, there are no reports on the effect of central cage location within the glenoid vault on RTSA outcomes when using the Exactech® Equinoxe® Reverse System. The purpose of this study was to determine the appropriate cage location in relation to the glenoid vault and monitor for vault and/or cortex penetration by the cage. METHODS: Data were retrospectively collected from the Samsung Medical Center (SMC) and Seoul National University Bundang Hospital (SNUBH). Patients who underwent RTSA between November 2016 and February 2018 were enrolled. Glenoid vault depth, central cage location within the vault were examined. Inferior glenoid rim-center distance, inferior glenoid rim-cage distance, and center-cage center distances were collected. RESULTS: Twenty-two patients were enrolled. Three SNUBH patients had inappropriate central cage fixation (33.3%) versus 4 SMC patients (30.8%). All cage exposures were superior and posterior to the glenoid vault. Mean center-cage distance was 5.0 mm in the SNUBH group and 5.21 mm in the SMC group. Center-prosthesis distance was significantly longer in the inappropriate fixation group than in the appropriate fixation group (p<0.024). CONCLUSIONS: To ensure appropriate glenoid baseplate fixation within the glenoid vault, especially in a small glenoid, the surgeon should place the cage lower than usually targeted, and it should overhang the inferior glenoid rim.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the perception and satisfaction of cancer patients participating in clinical trials of anticancer drugs and the factors affecting their satisfaction. METHODS: The participants were cancer patients who participated in more than two cycles of clinical trials at a tertiary hospital in Seoul, Korea. Questionnaires were used to assess the perception and satisfaction of clinical trials of anticancer drugs. RESULTS: A total of 106 patients participated. The average perception and satisfaction regarding clinical trials among patients on a 5 point scale was 3.99±0.45 and 4.09±0.55 respectively. There was a significant difference in the correlation among participants' perception and their satisfaction (r =.67, p<.001). Regression analysis revealed that satisfaction was explained by, perception of clinical trials (β =.67, p<.001), participation period 30~59 days (β =.21, p=.009), and participation period over 60 days (β=.20, p=.013). These variables explained 48.7% of the variance of clinical trial satisfaction. CONCLUSION: The results of this study suggest that changes in perceptions of clinical trials are needed to improve satisfaction of anticancer drug clinical trials. This can be used as a basis for improving the quality of clinical trials and education programs for cancer patients participating in clinical trials.

ABSTRACT

PURPOSE: Isolated iliac artery aneurysm (IIAA) is uncommon. It is frequently treated by endovascular aneurysm repair (EVAR). This study was to evaluate treatment results of IIAA and survey aortic diameter after EVAR. METHODS: Patients treated for IIAA in Seoul St. Mary's Hospital and Bundang Seoul National University from 2005 to April 2016 were retrospectively enrolled. The inclusion criteria of IIAA was >30 mm of iliac artery aneurysm without abdominal aortic aneurysm, which was treated by open surgical repair (OSR) or EVAR. Patients' clinical characteristics, treatment results, and mortality were obtained from electronic medical records. Diameters of aorta and iliac arteries were measured periodically with scheduled interval based on CT scans. RESULTS: Forty-nine patients (40 males; mean age, 71.9 ± 11.1 years) were enrolled. Five ruptured IIAAs were treated with EVAR (n = 1) or hybrid methods (n = 4). The diameter of ruptured IIAAs was 65 ± 31.4 mm, which was not significantly different from that of elective (44.3 ± 17.0 mm). Forty-four elective IIAA underwent 9 OSR, 31 EVARs, and 3 hybrid treatments (15 bifurcated and 12 straight stent-grafts). Treatment success rate was 93.8% without hospital mortality. There were 4 type I endoleak, 1 type II endoleak, and 1 type III endoleak without aneurysm-related mortality during follow-up. However, the aortic diameter was increased over time though there was no change or decrease in common iliac artery's diameter. CONCLUSION: Treatment of IIAA included various endovascular modalities as well as open surgery. Regular surveillance is still needed due to aortic dilatation after its treatment.

ABSTRACT

BACKGROUND: Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. This study aims to update Korea's worldwide research productivity in the field of orthopedics using bibliometric methods and to provide Korean surgeons and researchers with insights into such research. METHODS: Articles published in the top 15 orthopedic journals between 2008 and 2017 were retrieved using the Web of Science. The number of articles, citations and h-index (Hirsch index), funding sources, institutions, and journal patterns were analyzed. RESULTS: Of the total 39,494 articles, Korea's contribution accounted for 5.6% (2,161 articles), ranking fifth in the world in the number of publications. Korea ranked sixth (with 29,456) for total citations worldwide but ranked 17th (13.64) in terms of average citation per item and 14th (55) in terms of h-index. Korea showed the most prolific productivity in the field of sports medicine and arthroscopy. The institution that produced the highest number of publications was Seoul National University (n = 386, 17.9%). CONCLUSIONS: Orthopedic research in South Korea demonstrated high productivity in terms of the number of publications in high-quality journals between 2008 and 2017. However, total citations and average citations per article were still relatively low. Efforts should be made to increase citation rates for further improvement in research productivity in the field of orthopedics.

ABSTRACT

OBJECTIVE: This study evaluated gender differences in the relationship between psychiatric distress and subjective tinnitus severity. METHODS: This cross-sectional study included 134 female and 114 male patients who visited the otology outpatient clinic at Seoul St. Mary’s Hospital for tinnitus from February to July 2015. Patients completed a series of instruments, including the Tinnitus Handicap Inventory, Beck Depression Inventory, Korean version of Brief Encounter Psychosocial Instrument (BEPSI-K), and visual analogue scales assessing various tinnitus characteristics (loudness, awareness, annoyance, and effect on life). RESULTS: Tinnitus severity did not significantly differ between the gender groups (p=0.632), and it correlated significantly with tinnitus characteristics and psychiatric distress. Partial correlations between tinnitus severity and depressive symptoms were stronger in males (r=0.411, p<0.01) than in females (r=0.304, p<0.01) while controlling for duration of tinnitus and tinnitus characteristics. However, stress (BEPSI-K) was positively correlated with tinnitus severity in only males (r=0.463, p<0.01). A multiple regression analysis revealed that effect of tinnitus on life, depressive symptoms, and stress were significantly associated with tinnitus severity in males, whereas only tinnitus annoyance and depressive symptoms were associated with tinnitus severity in females. CONCLUSION: Tinnitus severity was significantly correlated with depressive symptoms and stress, and there were gender differences in the relationship between tinnitus severity and psychiatric components. It is necessary to be vigilant of psychiatric symptoms among patients with tinnitus who visit the otology outpatient clinic, especially for male patients.

ABSTRACT

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) patients need parenteral nutrition because of nausea, vomiting, and mucositis caused by conditioning regimens. The demand for glutamine increases during the HSCT period. We evaluated the effects of glutamine-containing parenteral nutrition on the clinical outcomes of HSCT patients. METHODS: In this retrospective analysis, we reviewed HSCT patients from Seoul National University from August 2013 to July 2017. Depending on their glutamine supplementation status, 91 patients were divided into 2 groups: glutamine group (N=44) and non-glutamine group (N=47). We analyzed the rate of weight change, infection (clinically/microbiologically documented), complications (duration of mucositis and neutropenia, acute graft versus host disease), and 100-days mortality in each group. RESULTS: Regarding the clinical characteristics of the patients, there were no significant differences between the 2 groups except that there was a larger proportion of myeloablative conditioning regimen in the glutamine group (P=0.005). In the glutamine group, the average number of days of glutamine use, parenteral nutrition, and mucositis was 7.6±1.4, 14.6±9.9, and 13.3±9.5, respectively. Furthermore, multivariate analysis revealed odds ratios of 0.37 (95% CI, 0.14–0.96; P=0.042) and 0.08 (95% CI, 0.01–0.98; P=0.048) for clinically documented infection and 100-days mortality, respectively, in the glutamine group. CONCLUSION: Results showed that the glutamine group had less clinically documented infection and 100-days mortality than the non-glutamine group, but the other outcomes did not show significant differences. The extended duration of glutamine supplementation according to the period of total parenteral nutrition and mucositis should be considered.

ABSTRACT

BACKGROUND: It is very important to accurately enumerate CD34-positive (CD34+) cells for successful hematopoietic stem cell transplantation (HSCT). We evaluated the ability of the newly developed image based-immunofluorescence cell counter ADAMII (NanoEntek, Seoul, Korea) to enumerate CD34+ cells, which was improved through simultaneous CD45 analysis. METHODS: We enumerated CD34+ cells with ADAMII using 19 peripheral blood (PB) and 91 leukapheresis samples from HSCT donors. Analytical performance, including precision and linearity, was analyzed, and sample stability during storage was evaluated. Viable CD34+ cell count (vCD34) and viable CD45+ cell count (vCD45) and the percentage of viable CD34+ cells among viable CD45+ cells (CD34/CD45) as measured by ADAMII were compared with the corresponding values from two flow cytometry assays, using regression analysis. RESULTS: ADAMII demonstrated acceptable precision, as CV values of vCD34 from six samples with different counts were all < 10% (range: 3.49–9.51%). CV values of the vCD45 and CD34/45 ranged from 4.03% to 9.67% and from 2.48% to 10.07%, respectively. The linearity of vCD34 showed an excellent R 2 value (0.99) when analyzed using the intended count and flow cytometry data. The ADAMII and two flow cytometry-based assays generated very similar data for the PB and leukapheresis samples. CONCLUSIONS: ADAMII demonstrated excellent performance for use as a routine clinical assay in terms of CD34+ cell enumeration from PB and leukapheresis samples. Moreover, it could be used as a point-of-care-test for determining mobilization time and predicting an adequate apheresis stem cell product.

ABSTRACT

PURPOSE: The purpose of this study is to explore the balance of work-life and parenting experience of nurses. METHODS: This qualitative study used the phenomenological methodology proposed by Giorgi. In-depth interviews were conducted on a total of 10 participants working at hospitals in Seoul and Gyeongnam province in 2017 to collect data. RESULTS: Four main issues were deduced: “complex situation between work and parenting,” “conflict situation of being in a double bind between work and parenting,” “the power to endure both work and parenting,” and “finding hope between work and parenting. CONCLUSION: The findings in this study provide an in-depth understanding on the work-life balance and parenting experience of nurses. These findings should help in the development of solutions to the conflict between work and family for nurses and enable them to develop effective strategies.

ABSTRACT

BACKGROUND: Osteomyelitis is an intraosseous inflammatory disease characterized by progressive inflammatory osteoclasia and ossification. The use of quantitative analysis to assist interpretation of osteomyelitis is increasingly being considered. The objective of this study was to perform early diagnosis of osteomyelitis on digital panoramic radiographs using basic functions provided by picture archiving and communication system (PACS), a program used to show radiographic images. METHODS: This study targeted a total of 95 patients whose symptoms were confirmed as osteomyelitis under clinical, radiologic, pathological diagnosis over 11 years from 2008 to 2017. Five categorized patients were osteoradionecrosis, bisphosphonate-related osteonecrosis of jaw (BRONJ, suppurative and sclerosing type), and bacterial osteomyelitis (suppurative and sclerosing type), and the control group was 117 randomly sampled. The photographic density in a certain area of the digital panoramic radiograph was determined and compared using the “measure area rectangle,” one of the basic PACS functions in INFINITT PACS® (INFINITT Healthcare, Seoul, South Korea). A conditional inference tree, one type of decision making tree, was generated with the program R for statistical analysis with SPSS®. RESULTS: In the conditional inference tree generated from the obtained data, cases where the difference in average value exceeded 54.49 and the difference in minimum value was less than 54.49 and greater than 12.81 and the difference in minimum value exceeded 39 were considered suspicious of osteomyelitis. From these results, the disease could be correctly classified with a probability of 88.1%. There was no difference in photographic density value of BRONJ and bacterial osteomyelitis; therefore, it was not possible to classify BRONJ and bacterial osteomyelitis by quantitative analysis of panoramic radiographs based on existing research. CONCLUSIONS: This study demonstrates that it is feasible to measure photographic density using a basic function in PACS and apply the data to assist in the diagnosis of osteomyelitis.

ABSTRACT

PURPOSE: To investigate the effects of transplantation of a circumferentially-trephined autologous oral mucosal graft using a vacuum trephine on ocular surface reconstruction in patients with limbal stem cell deficiency. METHODS: Patients with a limbal stem cell deficiency who underwent transplantation of autologous oral mucosal graft performed by a particular surgeon in Seoul National University Hospital were included. The medical records of these five patients were retrospectively reviewed. The lower labial mucosal graft inside the inferior lip was trephined to a depth of 250 µm using a donor vacuum trephine with a 9-mm diameter. Outside markings were made using a 14-mm intraoperative keratometer. The oral mucosal graft was dissected under a microscope using a Beaver mini-blade as either a ring or a crescent-shaped strip with a 5-mm width. The mucosal graft was transplanted onto the limbus in the limbal-deficient eye. Best-corrected visual acuity and corneal status were measured during the follow-up period. RESULTS: Four patients were diagnosed with Stevens-Johnson syndrome and one was diagnosed with atopy-associated immune keratitis. The mean follow-up period was 10.4 ± 2.9 months. After 4 months, visual acuity improved in all patients, and the mean improvement in logarithm of the minimum angle of resolution visual acuity was 0.526 ± 0.470 (range, 0.15 to 1.10). Corneal surface erosion and neovascularization decreased in four patients, and stromal opacity decreased in two patients. The engraftments maintained ocular surface stabilization in four of the five patients at the last follow-up. CONCLUSIONS: Transplantation of circumferential autologous oral mucosal grafts may be effective for the treatment of limbal stem cell deficiency.

ABSTRACT

PURPOSE: To investigate the risk factors of diabetic nephropathy in patients with diabetic retinopathy requiring panretinal photocoagulation (PRP) and the visual prognosis. METHODS: A retrospective review of electronic medical records was conducted at Seoul St. Mary's Hospital, comprising 103 patients with type 2 diabetes mellitus and diabetic retinopathy who underwent PRP from 1996 to 2005. Patients with type 1 diabetes mellitus, non-diabetic renal disease, non-diabetic retinal disease, visually significant ocular disease, high-risk proliferative diabetic retinopathy, and advanced diabetic retinopathy were excluded. The patients were divided into three groups: no nephropathy (group 1, n = 45), microalbuminuria (group 2, n = 16), and advanced nephropathy (group 3, n = 42). Duration of diagnosis of retinopathy and nephropathy, glycosylated hemoglobin, visual acuity, complications, and treatment history were investigated. RESULTS: The mean glycosylated hemoglobin of group 3 (8.4 ± 1.2) was higher than that of group 1 (7.7 ± 1.0) or group 2 (7.7 ± 1.0) (p = 0.04). Mean interval from PRP to diagnosis of nephropathy was 8.8 ± 6.0 years in group 2 and 8.7 ± 4.9 years in group 3. The significant decrease in visual acuity in group 3 (28 eyes, 35.9%) was significantly higher than that in group 1 (15 eyes, 18.1%, p = 0.01) or group 2 (6 eyes, 20.7%, p = 0.03). Only vitreous hemorrhage showed a significantly higher incidence in groups 2 and 3 than in group 1 (p = 0.02). Multivariate regression analysis revealed that female sex and lower glycosylated hemoglobin were significantly associated with a protective effect on development of nephropathy. CONCLUSIONS: In the clinical setting, many patients with PRP-requiring diabetic retinopathy develop nephropathy an average of 8 to 9 years after PRP. Male sex and higher glycosylated hemoglobin could be risk factors of nephropathy.

ABSTRACT

PURPOSE: This study was performed to investigate the current status of pediatric palliative care provision and how it is perceived by the palliative care experts. METHODS: A descriptive study was conducted with 61 hospice institutions. From September through October 2017, a questionnaire was completed by experts from the participating institutions. Data were analyzed using SPSS 21.0. RESULTS: Among 61 institutions, palliative care is currently provided for pediatric cancer patients by 11 institutions (18.0%), all of which are concentrated in Seoul, Incheon and Gyeonggi and Gyengsang provinces; 85.2% of all do not plan to provide specialized pediatric palliative care in the future. According to the experts, the main barriers in providing pediatric palliative care were the insufficient number of trained specialists regardless of the delivery type. Experts said that it was appropriate to intervene when children were diagnosed with cancer that was less likely to be cured (33.7%) and to move to palliative care institutions when their conditions worsened (38.2%); and it was necessary to establish a specialized pediatric palliative care system, independent from the existing institutions for adult patients (73.8%). CONCLUSION: It is necessary to develop an education program to establish a nationwide pediatric palliative care centers. Pediatric palliative care intervention should be provided upon diagnosis rather than at the point of death. Patients should be transferred to palliative care institutions after intervention by their existing pediatric palliative care team at the hospital is started.

ABSTRACT

BACKGROUND/AIMS: We investigated the risk of multidrug-resistant, gram-negative bacteria (MDRGNB) in hospitalized elderly patients from non-hospital long-term care facilities (LTCFs) and the antibiotic prescription pattern. METHODS: All clinical cultures obtained within 48 hours of hospitalization from elderly patients of at least 55 years of age arriving at a 623-bed, public teaching hospital in Seoul, Republic of Korea from LTCFs between April 1, 2011 and April 1, 2012 were collected retrospectively. RESULTS: During this period, 365 elderly persons from 13 LTCFs were hospitalized. This study enrolled 135 patients who had cultures performed. In this group, 27.4% harbored MDRGNB at hospitalization. The presence of MDRGNB during prior hospitalization was the only risk factor that predicted harboring it (p = 0.043, odds ratio = 5.00, confidence interval = 1.049-23.834). Combinations of antibiotics or carbapenems were used initially in 35.6% of the patients, and this did not affect the mortality rate in this population. CONCLUSIONS: Hospitalized elderly patients from non-hospital LTCFs need more attention. Judicious antibiotic selection is needed according to the risk factor of harboring MDRGNB for antibiotics stewardship.

ABSTRACT

OBJECTIVES: The aim of this study was to investigate cancer patients’ utilization of tertiary hospitals in Seoul before and after the benefit expansion policy implemented in 2013. METHODS: This was a before-and-after study using claims data of the Korean National Health Insurance Service from 2011 to 2016. The unit of analysis was inpatient episodes, and inpatient episodes involving a malignant neoplasm (International Classification of Diseases, Tenth Revision codes: C00-C97) were included in this study. The total sample (n=5 565 076) was divided into incident cases and prevalent cases according to medical use due to cancer in prior years. The tertiary hospitals in Seoul were divided into two groups (the five largest hospitals and the other tertiary hospitals in Seoul). RESULTS: The proportions of the incident and prevalent episodes occurring in tertiary hospitals in Seoul were 34.9% and 37.2%, respectively, of which more than 70% occurred in the five largest hospitals in Seoul. Utilization of tertiary hospitals in Seoul was higher for inpatient episodes involving cancer surgery, patients with a higher income, patients living in areas close to Seoul, and patients living in areas without a metropolitan city. The utilization of the five largest hospitals increased by 2 percentage points after the policy went into effect. CONCLUSIONS: The utilization of tertiary hospitals in Seoul was concentrated among the five largest hospitals. Future research is necessary to identify the consequences of this utilization pattern.

ABSTRACT

OBJECTIVES: The purpose of this study was to investigate the job satisfaction level of the dental staff working at oral health centers for people with disabilities. METHODS: A questionnaire survey was conducted with 73 dentists and dental hygienists working at seven regional oral health centers for people with special needs and dental hospitals for people with disabilities in Seoul. The questionnaire consisted of seven questions across two subscales: general satisfaction (4 questions) and satisfaction with wage and welfare (3 questions). The internal consistency of the questionnaire items was assessed using Cronbach's alpha (0.80). The responses were analyzed using a t-test with SPSS (version 23.0). RESULTS: Of the 73 dental staff members, 50% were dentists, 64% were women, and participants' average age was 30 years. In total, 58% of the participants had up to five years of experience working with people with disabilities, 42% of them worked full-time, and each participant treated an average of 200 patients with disabilities per month. The participants reported that their salary was relatively low. Dental hygienists had higher satisfaction level than dentists in the institution's welfare work. The more full-time workers answered, the more suitable they are for their work. CONCLUSIONS: The job satisfaction level of most professionals working in oral health centers for people with disabilities was not very high but they felt rewarded by their welfare work. It was inferred that it is necessary to examine and improve institutional support aspects such as human resource support. Increasing the number of centers in the central region is also needed.

ABSTRACT

PURPOSE: This study aims to investigate the trend in medical travel by non-Seoul residents to Seoul for treatment of prostate cancer and also to investigate the possible factors affecting the trend. MATERIALS AND METHODS: This study represents a retrospective cohort study using data from theKoreanNationalHealth Insurance System from 2002 to 2015. Annual trends were produced for proportions of patients who traveled according to the age group, economic status and types of treatment. Multiple logistic analysiswas used to determine factors affecting surgeries at medical facilities in Seoul among the non-Seoul residents. RESULTS: A total of 68,543 patients were defined as newly diagnosed prostate cancer cohorts from 2005 to 2014. The proportion of patients who traveled to Seoul for treatment, estimated from cases with prostate cancer-related claims, decreased slightly over 9 years (28.0 at 2005 and 27.0 at 2014, p=0.02). The average proportion of medical travelers seeking radical prostatectomy increased slightly but the increase was not statistically significant (43.1 at 2005 and 45.4 at 2014, p=0.26). Income level and performance ofrobot-assisted radical prostatectomy were significant positive factors for medical travel to medical facilities in Seoul. Combined comorbidity diseases and year undergoing surgery were significant negative factors for medical travel to medical facilities in Seoul. CONCLUSION: The general trend of patients travelling from outside Seoul for prostate cancer treatment decreased from 2005 to 2014. However, a large proportion of traveling remained irrespective of direct distance from Seoul.

ABSTRACT

PURPOSE: Despite the successful use of tyrosine kinase inhibitors (TKIs) in cancer patients, their effect on herpes zoster development has not been studied. The aim of this study was to evaluate and compare the effects of epidermal growth factor receptor (EGFR) TKI and cytotoxic chemotherapy on the risk of herpes zoster development in non-small cell lung cancer (NSCLC) patients. MATERIALS AND METHODS: We conducted a medical review of all eligible NSCLC patients in Seoul National University hospital between 2002 and 2015. We classified patients based on whether they previously underwent EGFR TKI therapy into either the TKI group or the cytotoxic group. We compared the incidence rates of herpes zoster during TKI therapy and cytotoxic chemotherapy. Additionally, the longitudinal risk of herpes zoster from TKIs was analyzed using the incidence rate ratio (IRR) of the TKI group to the cytotoxic group and the log-rank test of the Kaplan-Meier method. RESULTS: Of the 2,981 NSCLC patients, 54 patients (1.54%) developed herpes zoster. In the TKI group (2,002 patients), the IRR of herpes zoster during TKI therapy compared to that during cytotoxic chemotherapy was 1.05 (95% confidence interval [CI], 0.53 to 2.09). The IRR of the TKI group compared to the cytotoxic group was 1.33 (95% CI, 0.64 to 2.76). The Kaplan-Meier cumulative risk of both groups was not significantly different. CONCLUSION: Our results show that the incidence rate of herpes zoster in the TKI group was not statistically different from the incidence in the cytotoxic group during and after chemotherapy in NSCLC patients.

ABSTRACT

Viral respiratory infections are one of the most common infections worldwide. It is important to detect the virus early and precisely. In this study, we evaluated the limit of detection (LoD) and usefulness of the Real-Q RV Detection kit (BioSewoom, Seoul, Korea). We measured the LoD of the Real-Q RV Detection kit using 10 strains of standard viruses. We then compared the detection results by the Allplex Respiratory Panel Assay kit (Seegene, Seoul, Korea) using 123 clinical specimens. The discrepant results were confirmed by sequencing. Among the 10 standard viruses, the LoD of human rhinovirus (HRV) was the lowest and that of parainfluenza virus 2 and 3 was relatively high as detected by Real-Q RV Detection kit. Agreements of the two kits ranged from 95.9% to 100%. Three specimens detected negative by the Allplex Respiratory Panel kit were detected as adenovirus (AdV) by the Real-Q RV Detection kit and were confirmed by sequencing. Similarly, a specimen detected negative by the Allplex Respiratory Panel kit was detected as HRV by the Real-Q RV Detection kit and was confirmed by sequencing. A specimen detected as human enterovirus by the Allplex Respiratory Panel kit was detected as HRV by the Real-Q RV Detection kit and was confirmed by sequencing. Real-Q RV Detection kit showed good diagnostic performance and can be useful for detecting major viruses that cause respiratory infections.

ABSTRACT

PURPOSE: Laparoscopic major liver resection (major LLR) remains a challenging procedure because of the technical difficulty. Several significant technical innovations have been applied in our center since 2012. They include routine application of bipolar electrocautery, initiation of temporary increase of intra-abdominal pressure during bleeding events from veins to balance the central venous pressure, and use of temporary inflow control of the Glissonean pedicle. This study evaluated the impact of these technique modifications in patients with major LLR. METHODS: Between January 2004 and February 2015, a total of 606 patients underwent LLR at Samsung Medical Center in Seoul, Korea. Major LLR was employed in 233 cases. All major LLR procedures were anatomical resections performed with a totally laparoscopic approach. We compared surgical parameters of right hepatectomy (RH), left hepatectomy (LH), and right posterior sectionectomy (RPS) before and after 2012. RESULTS: Open conversion rates of RH and LH and estimated blood loss in RPS significantly decreased after 2012. The postoperative complication rate of major LLR was 12.7% and was similar before and after 2012. Bile leakage was the most common complication (3.2%). CONCLUSION: The modifications of surgical techniques resulted in good outcomes for laparoscopic major LLR. We recommend routine application of these techniques to improve outcomes, especially in patients requiring major liver resection.
