ABSTRACT

A death certificate (DC) can be considered a legal document and in terms of societal use, it is a public document. A DC includes facts such as the time and place of death, as well as judgments as to the cause and manner of death. Whether it pertains to facts or judgments, recording false information results in a false DC. According to the National Association of Medical Examiners (NAME) in the United States, it is acknowledged that there are varying opinions and approaches when it comes to classifying the manner of death. Therefore, it may require a final judgment, including input from the legal system. Generally, deaths resulting from complications that occur during drug administration or medical procedures are classified as natural deaths, while deaths due to unforeseen complications that occur suddenly, are categorized as accidental deaths. Applying this classification by NAME to the principles and legal precedents related to the duty of explanation and medical lowas of the Korean Medical Association, it is reasonable to classify deaths resulting from complication, during medical care, as natural death. However, if the death occurs due to injury or poisoning during medical care, it falls under external causes, according to the principle of following the primary cause. In conclusion, it is considered reasonable to classify complications that occur during medical treatment as natural deaths when they are foreseeable and within the accepted range of complications determined by medical standards at that the time.

ABSTRACT

The South Korean Supreme Court decision (2009Da17471), May 21, 2009, on removing life-sustaining medical care from persistent vegetative patients gave consent to death with dignity and initiated a lively debate in South Korea. The legal grounds for this decision were based on dignity, worth, and the right to pursue happiness regulated in Article 10 of the Constitution, The Death with Dignity Act was legislated as a law for life-sustaining medical care through debate and agreement on February 3, 2016, and has since been revised four times. However, there are some issues to discuss with this Act. First, the definition of the process of dying is unclear because the determining point of the dying process is different from the status of the attachment or detachment of an artificial ventilator. Second, the purpose of this law is the protection of dignity, worth, and the right to pursue happiness. As nutrition, fluid, and oxygen must be continuously supplied, even if the artificial ventilator is removed, is it reasonable to suggest that supplying these continuously achieves Article 10 of the Constitution? Third, if the withdrawal of life-sustaining medical care is possible or permitted without the patient’s approval, what is the legal value of advance directives? Fourth, it is whether death with dignity could be extended to the euthanasia. Conclusively, it may be necessary to partially revise the law for life-sustaining medical care through further debate and agreement.

ABSTRACT

BACKGROUND: Rhinitis was the most frequently diagnosed disorder among users of humidifier disinfectants (HDs). The aim of our study was to investigate on the relationship between allergic rhinitis (AR) and HD uses.METHODS: Our study used the data from the eighth Panel Study on Korean Children; a total of 1,540 participants were enrolled. The χ² test and multiple logistic regression analyses were conducted to debunk the association between AR and HD uses.RESULTS: In our analysis, odds ratios (ORs) of doctor-diagnosed AR increased significantly when simply the response of whether HDs were used in the past was considered. When the brands of HD were considered, ORs of doctor-diagnosed AR were found to be increased significantly for those who have used polyhexamethylene guanidine phosphate/oligo(2-[2-ethoxy]-ethoxyethyl)guanidinium-containing HDs (model 3: 1.41, 95% confidence interval [CI]: 1.02–1.95). However, once duration of usage was additionally considered, ORs of doctor-diagnosed AR increased significantly only for those who have used chloromethylisothiazolinone/methylisothiazolinone-containing HDs for more than or equal to 3 months (model 3: 2.08, 95% CI: 1.17–3.69). Further, past use of HD was associated with significantly increased ORs of AR diagnosed before 2013 (model 3: 1.35, 95% CI: 1.02–1.79).CONCLUSIONS: Results of our study suggest that past uses of HDs may be associated with an increased risk of AR.

ABSTRACT

The Supreme Court decision made on May 21, 2009 about the withdrawal of futile life-prolonging medical care from a persistently vegetative patient provided a legal basis for patients to consent to death with dignity, and also spurred a lively debate in Korea. The legal grounding of this decision was based on the principles of human dignity, worth, and the right to pursue happiness articulated in the Article 10 of the Constitution. The Death with Dignity Act was legislated to regulate decisions about life-prolonging medical care on February 3, 2016, after extensive debate and a focus on consensus that led to two revisions. However, the issue has not been completely resolved. First, the definition of the process of dying is unclear, because the points that determine whether a patient is dying are different from a simple assessment of whether an artificial ventilator should be attached or detached. Second, the purpose of this law is the protection of human dignity, worth, and the right to pursue happiness. However, nutrition, fluids, and oxygen must continue to be supplied, even after cessation of life-prolonging medical care. Is providing a continuous supply of nutrition, fluids, and oxygen a reasonable way to satisfy the goals of Article 10 of the Constitution? Third, if the withdrawal of life-prolonging medical care is possible based on the family's agreement without the patient's input, what is the legal value of advance directives? In conclusion, it may be necessary to partially revise the law regulating decisions on the withdrawal of life-prolonging medical care through further debate.

ABSTRACT

BACKGROUND: Depression is considered as a risk factor for cardiovascular disease (CVD) and associated with changes in individuals' health status that might influence CVD risk. However, most studies have scrutinized this relationship on a rather narrower and specific study population. By focusing on general population of Korea, we sought to inspect the association of depression with CVD risk and cardiovascular risk factors. METHODS: The data from the first year (2016) of the 7th Korea National Health and Nutrition Examination Survey was used. Participants were classified by the Patient Health Questionnaire-9 (PHQ-9) score as such: normal group (PHQ-9 score 0–4), mild depression (MD) group (PHQ-9 score 5–9) and moderate and severe depression (MSD) group (PHQ-9 score 10–27). General linear model was used to analyze differences and the trend of mean CVD risk according to depression level. Adjusted odds ratios (AORs) were calculated by logistic regression to identify the association between depression and cardiovascular risk factors after adjusting for age. RESULTS: Mean CVD risk of MSD group was higher than that of normal group (p 125 mg/dL; AOR, 2.37; 95% CI, 1.25–4.50) and taking diabetes medications (AOR, 3.08; 95% CI, 1.65–5.72). MD group was associated with current smoking (AOR, 1.60; 95% CI, 1.18–2.17). Among women, MSD group was associated with high body mass index (≥ 25 kg/m2; AOR, 1.61; 95% CI, 1.11–2.32), large waist circumference (≥ 85 cm; AOR, 1.63; 95% CI, 1.12–2.37), current smoking (AOR, 5.11; 95% CI, 3.07–8.52) and taking diabetes medications (AOR, 2.62; 95% CI, 1.68–4.08). MD group was associated with current smoking (AOR, 1.86; 95% CI, 1.18–2.93). CONCLUSIONS: We suggest that depression is associated with increased risk for CVD occurrence in general population of Korea.

ABSTRACT

BACKGROUND: C-reactive protein (CRP) is an acute-phase protein whose level increases in response to tissue injury, infection, or other inflammation. It is used in clinical and forensic settings. Point-of-care (POC) testing has recently become available, and it is considered to be useful during postmortem examinations. However, laboratory testing of postmortem blood samples is difficult due to hemolysis and postmortem clotting. METHODS: The utility of POC testing for CRP during postmortem examination was evaluated using cardiac blood from the inferior vena cava. The whole blood sample was immediately tested using the POC instrument. Subsequently, the same sample was processed to obtain the serum, which was tested using common laboratory instruments. RESULTS: The postmortem POC test had a high positive predictive value and specificity, and the results strongly correlated with the laboratory test results. CONCLUSION: POC CRP testing is valid in postmortem examination and can be used in forensic medicine (postmortem inspection and autopsy).

ABSTRACT

The authors report a case of an otherwise healthy 33-year-old man who presented with intracerebral hemorrhage in the right frontal lobe following chronic methamphetamine use. An autopsy was performed within 2 days after death. The postmortem examination revealed cerebral edema and intracerebral and intraventricular hemorrhage. Microscopic examination revealed endovasculitis in the systemic vessels including the aorta and carotid and coronary arteries, but no aneurysm or arterio-venous malformation. Acute toxicity and chronic methamphetamine use was verified using blood and segmental hair analysis, respectively. Cerebrovascular accidents including stroke and intracerebral and subarachnoid hemorrhage are rare in young persons, but methamphetamine use is a risk factor for cerebrovascular accidents in young adults. Therefore, forensic pathologists should be aware of the acute and chronic harmful effects of methamphetamine. Detailed history taking and toxic screening tests for illicit drug use, especially methamphetamine, as well as a meticulous postmortem examination should be conducted in young patients who died due to cerebrovascular accident.

ABSTRACT

The diagnosis of cause of death (COD) or estimation of postmortem interval (PMI) is hard to perform using postmortem blood or other bodily fluids due to various biochemical changes that occur during the agonal phase or after death. To solve these problems, new paradigms and new analytical methods are needed. In this study, postmortem blood was fractionated with specific gravity 1.021, 1.029, 1.038, and 1.045, and the absorbance patterns of each sample of the 131 total cases (12 kinds of COD) were analyzed using a spectrometer. The absorbance was grouped into 9 patterns (ABS pattern 1 to 9) according to the wave length and the signal intensity. These patterns of postmortem blood were found to be distinctly different from the absorbance pattern of fresh blood. The analysis of ABS patterns is useful for the diagnosis of deaths due to acute or rapid bleeding, fire death, drowning and, in some cases, poisoning, but is not useful for the estimation of PMI.

ABSTRACT

BACKGROUND: Prevalence of thyroid cancer has been increasing rapidly worldwide, especially among women. There has been a debate as to whether such an increase represents consequences of over-diagnosis or a true increase. To find the occupational risk of Korean female workers in different industry sectors, we analyzed the data of Korean female workers. METHODS: National Female Worker Cohort data that contain information on total female workers were used for our analysis of prevalence of thyroid cancer (C73 according to KCD-5, 6 code) derived from National Health Insurance data. By combining industrial codes from National Health Insurance Service and those from Korea Workers’ Compensation and Welfare Service, the classification of industrial codes became to consist of the total of thirty three representing both non-office (NO) and office (O) categories. Both an internal comparison among female workers within the cohort and an external comparison to compare female workers with Korean general female population were carried out. RESULTS: Among 149,258 female workers, 2,641 cases of thyroid cancers were identified. Differences in prevalence of thyroid cancer between female workers (40.5%) and general Korean female population (32.6%) were observed; however, the differences in prevalence of thyroid cancer between NO workers and O workers were not apparent. An analysis involving workers in Financial and insurance activities sector revealed that, standardized prevalence rate (SPR) of both NO (2.96, 95% CI = 2.01–4.20) and O workers (3.68, 95% CI = 3.10–4.33) increased significantly and that an AOR (adjusted odds ratio) increased marginally (1.38, 95% CI = 0.97–1.96). Further, when stratified in respect to the duration of employment, an AOR of female workers having been employed for more than 8 years showed a significant increase (1.63, 95% CI = 1.07–2.49). CONCLUSIONS: Female workers had a higher risk of thyroid cancer than general female population but the difference between NO workers and O workers was not found to be significant in most industrial sectors. Further studies using data with information regarding specific occupational exposures are needed.

ABSTRACT

PURPOSE: There is still a clinical need to easily evaluate the metastatic status of lymph nodes during breast cancer surgery. We hypothesized that ex vivo shear-wave elastography (SWE) would predict precisely the presence of metastasis in the excised lymph nodes. METHODS: A total of 63 patients who underwent breast cancer surgery were prospectively enrolled in this study from May 2014 to April 2015. The excised axillary lymph nodes were examined using ex vivo SWE. Metastatic status was confirmed based on the final histopathological diagnosis of the permanent section. Lymph node characteristics and elasticity values measured by ex vivo SWE were assessed for possible association with nodal metastasis. RESULTS: A total of 274 lymph nodes, harvested from 63 patients, were examined using ex vivo SWE. The data obtained from 228 of these nodes from 55 patients were included in the analysis. Results showed that 187 lymph nodes (82.0%) were nonmetastatic and 41 lymph nodes (18.0%) were metastatic. There was significant difference between metastatic and nonmetastatic nodes with respect to the mean (45.4 kPa and 17.7 kPa, p<0.001) and maximum (55.3 kPa and 23.2 kPa, p<0.001) stiffness. The elasticity ratio was higher in the metastatic nodes (4.36 and 1.57, p<0.001). Metastatic nodes were significantly larger than nonmetastatic nodes (mean size, 10.5 mm and 7.5 mm, p<0.001). The size of metastatic nodes and nodal stiffness were correlated (correlation coefficient of mean stiffness, r=0.553). The area under curve of mean stiffness, maximum stiffness, and elasticity ratio were 0.794, 0.802, and 0.831, respectively. CONCLUSION: Ex vivo SWE may be a feasible method to predict axillary lymph node metastasis intraoperatively in patients undergoing breast cancer surgery.

ABSTRACT

PURPOSE: Although sentinel lymph node biopsy (SLNB) can accurately represent the axillary lymph node (ALN) status, the false-negative rate (FNR) of SLNB is the main concern in the patients who receive SLNB alone instead of ALN dissection (ALND). MATERIALS AND METHODS: We analyzed 1,886 patientswho underwent ALND after negative results of SLNB, retrospectively. A logistic regression analysis was used to identify risk factors associated with a false-negative (FN) result. Cox regression model was used to estimate the hazard ratio of factors affecting disease-free survival (DFS). RESULTS: Tumor located in the upper outer portion of the breast, lymphovascular invasion, suspicious node in imaging assessment and less than three sentinel lymph nodes (SLNs) were significant independent risk factors for FN in SLNB conferring an adjusted odds ratio of 2.10 (95% confidence interval [CI], 1.30 to 3.39), 2.69 (95% CI, 1.47 to 4.91), 2.59 (95% CI, 1.62 to 4.14), and 2.39 (95% CI, 1.45 to 3.95), respectively. The prognostic factors affecting DFS were tumor size larger than 2 cm (hazard ratio [HR], 1.86; 95% CI, 1.17 to 2.96) and FN of SLNB (HR, 2.51; 95% CI, 1.42 to 4.42) in SLN-negative group (FN and true-negative), but in ALN-positive group (FN and true-positive), FN of SLNB (HR, 0.64; 95% CI, 0.33 to 1.25) did not affect DFS. CONCLUSION: In patients with risk factors for a FN such as suspicious node in imaging assessment, upper outer breast cancer, less than three harvested nodes, we need attention to find another metastatic focus in non-SLNs during the operation. It may contribute to provide an exact prognosis and optimizing adjuvant treatments.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the radiological and clinical results of plate fixation and external fixation with additional devices for treating distal radius fracture in AO type C subtypes, and propose a treatment method according to the subtypes. MATERIALS AND METHODS: Two hundred and one AO type C distal radius fracture patients were retrospectively reviewed. Eighty-five patients in group 1 were treated with volar or dorsal plate, and 116 patients in group 2, were treated with external fixation with additional fixation devices. Clinical (range of mtion, Green and O'Brien's score) and radiological outcomes were evaluated. RESULTS: At the 12-month follow-up, group 1 showed flexion of 64.4°, extension of 68.3°, ulnar deviation of 30.6°, radial deviation of 20.8°, supination of 76.1°, and pronation of 79.4° in average; group 2 showed flexion of 60.5°, extension of 66.9°, ulnar deviation of 25.5°, radial deviation of 18.6°, supination of 73.5°, and pronation of 75.0° in average. The mean Green and O'Brien score was 92.2 in group 1 and 88.6 in group 2. The radial height of group 1 and group 2 was 11.6/11.4 mm; radial inclination was 23.2°/22.5°; volar tilt was 11.6°/8.7°; and the ulnar displacement was 1.27/0.93 mm. CONCLUSION: Judicious surgical techniques during device application and tips for postoperative management during external fixation can produce similar clinical results compared with internal fixation patients.

ABSTRACT

Bacterial culture and identification are both useful in the clinical and forensic fields, although the postmortem changes in human microbiology are poorly understood. This study aimed to identify bacteria that were considered normal flora in postmortem body fluid samples. Bacterial culture and identification testing were performed for 336 body fluid samples (e.g., cardiac blood, peripheral blood, pericardial fluid, pleural fluid, peritoneal fluid, cerebrospinal fluid, and urine) from 129 forensic autopsy cases. Bacteria were identified using both genetic and biochemical methods, and testing for C-reactive protein (CRP) was used to identify the presence of antemortem inflammation. Among the 129 autopsy cases, 79 cases (69.3%) were negative for CRP, and bacterial culture and identification testing were performed for 185 samples from those 79 cases. Bacteria that were considered both normal flora and pathogens were identified in the CRP-negative cases. Therefore, the results from postmortem bacterial culture and identification testing should be interpreted in the context of other postmortem examination, including CRP testing. Furthermore, case selection, postmortem testing, and interpretations of the results should be performed by both clinical bacteriologists and forensic pathologists. To best of our knowledge, this is the first study to examine normal flora in various postmortem body fluid samples form Korean autopsy cases.

ABSTRACT

BACKGROUND: Discrimination based on type of employment against non-regular workers is still a social issue. However, there are few studies on job factors that affect the discrimination experience in each type of employment or the association between discrimination and health impact indicators. This study examined occupational health characteristics according to discrimination experience and relating factors that affect discrimination experience. METHODS: This study used the 4th Korean Working Conditions Survey (2014) provided by the Korea Occupational Safety and Health Agency. Among the 50,000 workers, 7731 non-regular wage workers were selected as study population. To examine differences in discrimination experience, we used a t-test on occupational risk factors, occupational stress, occupational characteristics, health impact indicators. To identify the factors that affected discrimination experience, we performed binomial logistic regression analysis. RESULTS: The discrimination experience rate was significantly higher in male, aged less than 40 years old, above high school graduate than middle school graduate, higher wage level, shorter employment period and larger company's scale. As factors related to discrimination experience, they experienced discrimination more as occupational stress was higher and when they were temporary or daily workers rather than permanent workers, work patterns were not consistent, and the support of boss was low. It showed that physical, musculoskeletal, and mental occupational risk scores and subjective job instability were higher and work environment satisfaction was lower in discrimination experienced group. CONCLUSIONS: The present study showed that the demographic and occupational factors were complexly related to discrimination experience in non-regular workers. The experience of discrimination had increased when occupational stress was higher, they were temporary or daily workers rather than permanent workers, work patterns were not consistent, and their boss' support was low. Improving various relating factors, (e.g. occupational stresses, employment status and occupational characteristics), this would ultimately expect to improve non-regular workers' discrimination.

ABSTRACT

Lumbar disk herniation is common. Because of the posterior longitudinal ligament, migration usually occurs into the ventral epidural space. Rarely, fragments migrate into the dorsal epidural space. A 57-year-old man presented with lower back pain and weakness on right hip flexion and right knee flexion. He had lower back pain 1 day previously and received a transforaminal epidural block at a local hospital. The next day, he reported weakness of the right lower extremity. Lumbar spine magnetic resonance imaging revealed a dorsal epidural lesion with compression of the thecal sac at L2–3. Initial differential diagnoses included epidural hematoma after the block, neoplasm, and a sequestrated disk. Posterior lumbar decompression was performed. The lesion was identified intraoperatively as a large herniated disk fragment. Posterior epidural herniation of a lumbar disk fragment is rare and may be difficult to diagnose preoperatively.
