ABSTRACT

SUMMARY: Metopic suture can be visualized from the nasion to the bregma along the arch of the frontal bone in mid-sagittal plane. Persistent metopic suture normally closing between 1st and 2nd year of life has also been related with ethnicity. The present study reports the presence of complete and incomplete metopic sutures in Nepalese and Korean population skulls which helps to shed light on its incidence rate. Out of 121 adult skulls in Nepalese population, metopic suture was found to be present in 33 skulls. Incomplete metopic sutures showed variations of morphology, like linear (6.61 %), V-shaped (8.26 %) and double incomplete (10.74 %) and two cases with complete metopic suture, which showed variation in interdigitation between its anterior and posterior ends. Korean population showed metopic suture to be present in 8 skulls out of 104 with metopism in 3 skulls. Incomplete metopic sutures like double incomplete (1.92 %) and linear (2.88 %) were also noted. Alterations to local strains could be the contributing factor for such variation and complexity of interdigitation, which occur during the growth of the braincase. The knowledge of the metopic suture and its variations according to ethnicity is important and should be considered to prevent wrong diagnosis. The presence of different types of metopic sutures as reported by the present study provides informative value on the presence and variation of such sutures in population depending on ethnicity and ought to be helpful in diagnostic sequences in emergency setting.


RESUMEN: La sutura metópica se puede visualizar desde nasión hasta el bregma a lo largo del arco del hueso frontal en el plano mediano sagital. La sutura metópica persistente que normalmente se cierra entre el primer y segundo año de vida, también se ha relacionado con el origen étnico. El presente estudio informa la presencia de suturas metópicas completas e incompletas en los cráneos de la población nepalesa y coreana, lo que además de entregar información sobre su tasa de incidencia. De 121 cráneos adultos en la población nepalesa, en 33 de ellos se encontró la sutura metópica. Las suturas metópicas incompletas mostraron variaciones de la morfología, como lineal (6,61 %), en forma de V (8,26 %) y doble incompleta (10,74 %), además de dos casos con sutura metópica completa, que mostraron variación en la interdigitación entre sus extremos anterior y posterior. De los 104 cráneos de la población coreana en 8 se presentó la sutura metópica y en 3 metopismo. También se observaron suturas metópicas incompletas como doble incompleta (1,92 %) y lineal (2,88 %). Las alteraciones en las etnias locales podrían ser el factor contribuyente para tal variación y complejidad de la interdigitación, que ocurre durante el crecimiento de la cráneo. El conocimiento de la sutura metópica y sus variaciones según el origen étnico es importante y debe considerarse para prevenir un diagnóstico incorrecto. La presencia de diferentes tipos de suturas metópicas según lo informado en el estudio, proporciona un valor informativo sobre la presencia y la variación de tales suturas en la población, dependiendo de la etnia, y debería ser útil en las secuencias de diagnóstico en situaciones de emergencia.

ABSTRACT

The objective of this study was to investigate factors affecting the return home one year after a stroke. The subjects of this study consisted of patients who participated in a large-scale multi-objective cohort study of initial stage stroke patients who were admitted to 9 representative hospitals in Korea. We analyzed the distribution of the subjects who had experienced stroke a year earlier by distinguishing the group who returned home and the other group that was hospitalized in rehabilitation hospitals. Based on this distribution, we evaluated the demographic, environmental, clinical, and psychological factors that can affect the return home. Overall, there were 464 subjects in the ‘Return home’ group and 99 subjects in the ‘Rehabilitation hospitalization’ group. job status, inconvenient housing structures, residential types, diagnosis, Functional Ambulation Categories, modified Rankin Scale, Korea-Modified Barthel Index, Function Independence Measure, Fugl-Meyer Assessment, Korean version of Mini-Mental State Examination, Korean version of Frenchay Aphasia Screening Test, Psychosocial Well-being Index-Short Form, Geriatric Depression Scale-Short Form, EuroQol-five Dimensional showed a significant difference between the 2 groups one year after the stroke. The factors affecting the return home one year after a stroke include functional status, activities of daily living, cognition, depression, stress, quality of life, job status. It is expected that factors affecting the rehabilitation of patients with stroke can be considered as basic data for establishing rehabilitation goals and treatment plans.

ABSTRACT

This study investigated how physical and cognitive function and psychological factors affected the health-related quality of life (HRQoL, hereafter HQ) of stroke patients in South Korea. The study enrolled 32 right-handed subjects with chronic cerebral infarction with disability and preserved cognitive function (Mini-Mental State Examination ≥ 20). Physical disability was assessed using the modified Rankin Scale (mRS) and Korean modified Barthel Index (KMBI). Quality of life was measured using the World Health Organization Quality of Life-Abbreviated form (WHOQOL-BREF, hereafter WB) and the 36-Item Short-form Health Survey (SF-36) in face-to-face interviews. Psychological distress was investigated using the Beck Depression Inventory Scale-II. The associations of each domain of WB and SF-36 were investigated using Pearson correlation analyses. Physical disability was negatively correlated with HQ in the SF-36. The physical function and bodily pain scales of the SF-36 were negatively correlated with physical disability. The general health domain of the SF-36 was negatively correlated with psychological scores. Emotional status was associated with physical health, social relationships, and general health in HQ. In summary, the severity of physical disability was associated with the patient's general and physical health and body pain. These findings suggest the importance of psychological, cognitive, and physiological interventions for improving the quality of life of patients after cerebral infarction.

ABSTRACT

BACKGROUND: The incidence of asthma exacerbation (AE) and the predictive value of spirometry and fractional exhaled nitric oxide (FeNO) in school children have not been evaluated.OBJECTIVE: We sought to evaluate the efficacy of spirometry measurement and FeNO monitoring for predicting AE in school children in the Cheongju area in Korea.METHODS: With parental agreement, we studied 170 students aged 7–12 years. Children were evaluated by an asthma specialist using baseline spirometry, skin prick test, seasonal FeNO measurement, and asthma control test. The study participants underwent a physical examination and their medical history was also evaluated by the specialist. They were assessed for asthma control status during regular doctor visits for 1 year.RESULTS: In total, 160 children (94.1%) completed follow-up and FeNO monitoring. Of which, 26 children (16.3%) had AE. AE was associated with male children and children with allergic rhinitis (p < 0.05). While, children with AE tended to have higher FeNO than those without AE, no significant difference was found. The maximum value of FeNO ≥35 ppb was associated with AE (p < 0.05). Children with AE had a significantly decreased baseline forced expiratory volume in 1 second/forced vital capacity (FEV₁/FVC), %predicted, forced expiratory flow at 25%–75% of FVC (FEF(25%–75%)). FEV₁/FVC < 80% was associated with AE in children regardless of inhalant allergen sensitization (all p < 0.05).CONCLUSION: Baseline spirometry had a predictive value of AE in school children. Sensitive spirometric parameters such as FEV₁/FVC and FEF(25%–75%) can be used as prognostic factors to predict future childhood AE. FeNO value ≥ 35 ppb during monitoring was associated with AE in school children.

ABSTRACT

PURPOSE: Hepatorenal syndrome (HRS) is a fatal complication in patients with end-stage liver disease awaiting liver transplantation (LT). HRS often develops in patients with high model for end-stage liver disease (MELD) score. This study investigated the outcomes of peritransplant management of HRS in a high-volume LT center in Korea for 2 years.METHODS: A total of 157 recipients that deceased donor liver transplantation (DDLT) from January 2017 to December 2018 were included. In-hospital mortality (IHM) was analyzed in relation to pre- and posttransplant application of renal replacement therapy (RRT).RESULTS: Primary diagnoses for DDLT were alcoholic liver disease (n = 61), HBV-associated liver cirrhosis (n = 48), retransplantation for chronic graft failure (n = 24), and others (n = 24). Mean MELD score was 34.6 ± 6.2 with 72 patients at Korean Network for Organ Sharing MELD status 2 (45.9%), 43 at status 3 (27.4%), 36 at status 4 (22.9%), and 6 at status 5 (3.8%). Pretransplant RRT was performed in 16 patients (10.2%) that did not show IHM. Posttransplant RRT was performed in 69 patients (44.0%), for whom IHM incidence was 15.9%. In 53 patients that had undergone de novo posttransplant RRT, IHM incidence increased to 20.8%. IHM in the 88 patients not requiring RRT was 2.3%.CONCLUSION: The majority of adult DDLT recipients in Korean MELD score-based allocation system have very high MELD scores, which is often associated with HRS. Pretransplant RRT appears to improve posttransplant survival outcomes. We thereby recommend that, if indicated, pretransplant RRT be performed while awaiting DDLT.

ABSTRACT

PURPOSE: Major liver resection and radical lymph node dissection has been accepted as a definite treatment of choice for hilar cholangiocarcinoma (HC). However, the perioperative and survival outcomes of right hemihepatectomy (RH) and left hemihepatectomy (LH) still remain controversial. Thus, this study aimed to compare the surgical and oncological outcomes of RH and LH in HC patients.METHODS: From January 2000 to January 2018, a total of 326 patients underwent surgical resection for HC at Yonsei University College of Medicine in Seoul, Korea. Among the 326 patients, we excluded 130 patients and selected 196 patients, who underwent hemihepatectomy with caudate lobectomy. Among these 196 patients, 114 patients underwent RH, and 82 patients underwent LH. We compared the clinicopathological features as well as the surgical and oncologic outcomes of the RH and LH groups.RESULTS: There were no significant differences in disease-free survival (P = 0.473) or overall survival (P = 0.946) in the RH and LH groups. The LH group had fewer complications compared with the RH group, including postoperative ascites (RH: 15 [13.2%] vs. LH: 3 [3.7%], P = 0.023); however, the LH group had more bile leakage complications (RH: 5 [4.4%] vs. LH: 12 [14.6%], P = 0.012). The average time lag from portal vein embolization to operation was 25.80 ± 12.06 days (n = 45). There was no difference in postoperative liver failure (P = 0.402), although there were significantly more frequent ascites after RH (P = 0.023).CONCLUSION: LH might be a good alternative option for the surgical treatment of HC given appropriate tumor location and biliary anatomy indications.

ABSTRACT

PURPOSE: We conducted a multi-institutional analysis to establish the epidemiological characteristics of recurrent inguinal hernia following hernia repair in patients across 4 institutions in Korea.METHODS: The retrospectively reviewed data included patient characteristics, hernia location, year of primary operation, type of hernia, timing of recurrence, primary operation type, and whether a mesh was used.RESULTS: Among 4,604 patients who underwent hernia repair surgery, 255 patients (5.5%; 13 females and 242 males; mean age, 63 years) were found to have recurrent hernia from January 2010 to April 2017. Recurrent indirect inguinal and direct hernias were observed in 47.1% and 49.4% of the patients, respectively. The recurrence of hernias within 1 year of surgery was the highest at 17.25%. Early and late recurrences was observed in 23.5% and 66.5% of the patients, respectively. Among the patients, 81.6% underwent open hernia repair at the time of initial surgery.CONCLUSION: Recurrence of hernia is most common in the first year after the initial surgery, and 23.5% of recurrent inguinal hernia was developed within 2 years. Patients underwent surgery after an average of 116 months (median value, 64 months) following the first operation. In patients with recurrent hernia, direct hernia was seen more frequent than indirect hernia whereas indirect hernia occurred more in patients with primary hernia.

ABSTRACT

BACKGROUND: As the spread of carbapenemase-producing Enterobacteriaceae poses a critical threat to public health, rapid detection of carbapenemase genes is urgently required for prompt initiation of appropriate antimicrobial therapy and infection control. We evaluated the performance of Xpert Carba-R v.2 (Cepheid, USA) compared with that of culture-based conventional PCR.METHODS: Using the results of 5,479 consecutive clinical rectal swabs, discrepant analysis (enriched culture followed by PCR) was performed for all discordant samples (N=100), which were Carba-R v.2-positive and culture-negative.RESULTS: Among the samples, 206 carbapenemase genes (3.6%) were detected by Carba-R v.2. The sensitivity and specificity were 95.0% and 98.1%, respectively. The positive predictive value (PPV) and negative predictive value (NPV) were 49.0% and 99.9%, respectively. Following discrepant analysis, the PPV increased to 73.5% and the low PPV (8.1%) of the 86 non-KPC improved to 48.8%. Among the 105 discrepancies, NDM was the most frequently observed (N=56), followed by KPC (N=26), VIM (N=10), IMP (N=8), OXA-48 (N=5). The threshold cycle values between discordant vs. concordant and resolved groups were significantly different (P<0.001).CONCLUSIONS: Carba-R v.2 is a rapid and sensitive method for detecting carbapenemase-encoding genes compared with culture-based conventional PCR. Most of our discrepant results were non-KPC genes. Thus, the clinical significance of the non-KPC positive cases detected by Carba-R v.2 should be investigated. This assay would be useful for deciding whether to isolate pre-exposed patients in hospital settings, based on the high specificity and NPV.

ABSTRACT

BACKGROUND: Differences in the performance of suggested warfarin dosing algorithms among different ethnicities and genotypes have been reported; this necessitates the development of an algorithm with enhanced performance for specific population groups. Previous warfarin dosing algorithms underestimated warfarin doses in VKORC1 1173C carriers. We aimed to develop and validate a new warfarin dosing algorithm for Korean patients with VKORC1 1173C.METHODS: A total of 109 patients carrying VKORC1 1173CT (N=105) or 1173CC (N=4) were included in this study. Multiple regression analysis was performed to deduce a new dosing algorithm. Following literature searches for genotype-guided warfarin dosing algorithms, 21 algorithms were selected and evaluated using the correlation coefficient (ρ) of actual dose and estimated dose, mean error, and root mean square error.RESULTS: The developed algorithm is as follows: maintenance dose (mg/week)=exp [3.223−0.009×(age)+0.577×(body surface area [BSA])+0.178×(sex)−0.481×(CYP2C9 genotype)+0.227×(VKORC1 genotype)]. Integrated variables explained 44% of the variance in the maintenance dose. The predicted and actual doses showed moderate correlation (ρ=0.641) with the best performance with a mean error of −1.30 mg/week. The proportion of underestimated groups was 17%, which was lower than with the other algorithms.CONCLUSIONS: This is the first study to develop and validate a warfarin dosing algorithm based on data from VKORC1 1173C carriers; it showed superior predictive performance compared with previously published algorithms.

ABSTRACT

BACKGROUND: Genetic counseling (GC) provides many benefits, including the identification of patients appropriate for testing, patient education, and medical management. We evaluated the current status of and challenges faced by GC practitioners in Korean hospitals.METHODS: An electronic survey was designed and conducted in 52 certified laboratory physicians belonging to the Korean Society of Laboratory Medicine, from August to September 2018. The questionnaires addressed three main categories of information: (1) current status of GC in hospitals; (2) essential qualifications of GC practitioners; and (3) challenges and perspectives for GC. Fisher's exact test was applied to analyze categorical data.RESULTS: Among a total of 52 participants who initially responded, 12 (23.1%) were performing GC either by direct or indirect care. GC clinics were opened regularly for one (33.3%) or more than three sessions (25.0%) per week; most respondents spent more time for pre-visit activities than in-person visits, both for a initial visit patient and for a follow-up visit patient. All laboratory physicians provided genetic information to their patients. Most recommended family genetic testing when indicated (91.7%), discussed disease management (75.0%), and/or ordered additional genetic testing (58.3%), and some referred patients to other specialists (8.3%).CONCLUSIONS: Both patients and laboratory physicians concede the advantage of GC performed by clinical geneticists; however, the practice of GC involves several challenges and raises some concerns. The cost and support required to implement GC need to be addressed in order to provide qualified GC in Korea.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness and safety of the combination of pegylated liposomal doxorubicin with carboplatin (CD) compared with those of carboplatin and paclitaxel (CP) for platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer in a real-world setting in Korea.METHODS: We enrolled relevant patients from 9 institutions. All patients received CD or CP as the second- or third-line chemotherapy in routine clinical practice during 2013–2018. The primary endpoints were progression-free survival (PFS) and toxicity. The secondary endpoint included the objective response rate (ORR).RESULTS: Overall, 432 patients (224 and 208 in the CD and CP groups, respectively) were included. With a median follow-up of 18.9 months, the median PFS was not different between the groups (12.7 vs. 13.6 months; hazard ratio, 1.161; 95% confidence interval, 0.923–1.460; p=0.202). The ORR was 74.6% and 80.1% in the CD and CP group, respectively (p=0.556). Age and surgery at relapse were independent prognostic factors. More patients in the CD group significantly experienced a grade 3 to 4 hematologic toxicity and hand-foot syndrome (13.8% vs. 6.3%), whereas grade 2 or more alopecia (6.2% vs. 36.1%), peripheral neuropathy (4.4% vs. 11.4%), and allergic/hypersensitivity reaction (0.4% vs. 8.5%) developed more often in the CP group.CONCLUSIONS: The safety and effectiveness of chemotherapy with CD in a real-world setting were consistent with the results from a randomized controlled study. The different toxicity profiles between the 2 chemotherapy (CD and CP) regimens should be considered in the clinical practice.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03562533

ABSTRACT

BACKGROUND: The purpose of this study was to identify the characteristics of appendicular lean mass (ALM) associated with rheumatoid arthritis (RA) and to analyze appendicular tissue components in patients with RA.METHODS: We prospectively reviewed of patients with RA who underwent dual energy X-ray absorptiometry in a single center. From data of 28 patients, ALM was calculated. Regression analysis was used to investigate the association between ALM and RA. Using propensity score matching, patients with RA were compared to the control group from 18,698 patients of Korea National Health and Nutrition Examination Surveys data. RA and control group were matched in a 1: 5, respectively.RESULTS: In regression model, there was significantly negative association between disease activity score and ALM index in patients with RA in unadjusted (β=−0.387, 95% confidence interval [CI], −0.729 to −0.045) and model adjusted for age, sex, and body mass index (β=−0.227, 95% CI, −0.451 to −0.003). In matching with age and sex, the arms fat mass and fat fraction of RA group were significantly lower than that of control group. In matching with age, sex, and body mass index, the ALM index and legs lean mass of RA group were significantly higher than control group.CONCLUSIONS: Patients with RA have a lower ALM with higher disease activity. In addition, we found that patients with RA had different tissue component in arms and legs compared to general population.

ABSTRACT

BACKGROUND: Alarm services in the Order Communication System improve awareness for related physicians including orthopaedic surgeons, internal medicine doctors, and other relevent doctors. This prospective observational multicenter study was to compare the diagnostic and treatment rates of osteoporosis between an alarm service group and a no alarm service group.METHODS: From January 2017 to december 2017, The subjects included patients aged 50 years or older with hip fractures from 16 hospital-based multicenter cohorts. Among the 16 hospitals, 5 university hospitals established an alarm service for osteoporosis management (i.e., Alarm group) and 11 university hospitals did not set-up alarm services (i.e., Control group). The rate of dual energy X-ray absorptiometry (DXA) test and the initiation rate of antiosteoporosis medications between the 2 groups were compared at enrollment and at 6 months follow-up.RESULTS: During the study period, 1,405 patients were enrolled. The DXA examination rate and initiation rate of osteoporosis treatment between the Alarm group and the Control group were 484 patients (89.8%) vs. 642 patients (74.1%) (P<0.001) and 355 patients (65.9%) versus 294 patients (33.9%) (P<0.001), respectively. At 6 months follow-up, the rate of anti-osteoporosis management between the 2 groups decreased (57.8% vs. 29.4%).CONCLUSIONS: This prospective multicenter study demonstrates that alarm services can improve awareness of physicians, and it resulted in a significantly higher rate of examination of DXA and initiation of anti-osteoporosis medication in the Alram group. Therefore, alarm service is a simple and effective tool to increase anti-osteoporosis management as part of the fractuure liaison service in South Korea.

ABSTRACT

BACKGROUND: Diabetes mellitus (DM) is the most common chronic metabolic disorder with an increasing prevalence worldwide. According to a previous study, physicians' treatment patterns or patients' behaviors change when they become aware of the risk for cardiovascular (CV) disease in patients with DM. However, there exist controversial reports from previous studies in the impact of physicians' behaviors on the patients' quality of life (QoL) improvements. So we investigate the changes in QoL according to physicians and patients' behavioral changes after the awareness of CV risks in patients with type 2 DM.METHODS: Data were obtained from a prospective, observational study where 799 patients aged ≥40 years with type 2 DM were recruited at 24 tertiary hospitals in Korea. Changes in physicians' behaviors were defined as changes in the dose/type of antihypertensive, lipid-lowering, and anti-platelet therapies within 6-month after the awareness of CV risks in patients. Changes in patients' behaviors were based on lifestyle modifications. Audit of Diabetes Dependent Quality of Life comprising 19-life-domains was used.RESULTS: The weighted impact score change for local or long-distance journey (P=0.0049), holidays (P=0.0364), and physical health (P=0.0451) domains significantly differed between the two groups; patients whose physician's behaviors changed showed greater improvement than those whose physician's behaviors did not change.CONCLUSION: This study demonstrates that changes in physicians' behaviors, as a result of perceiving CV risks, improve QoL in some domains of life in DM patients. Physicians should recognize the importance of understanding CV risks and implement appropriate management.

ABSTRACT

BACKGROUND: Diabetes mellitus is associated with an increased risk of dementia. We aimed to comprehensively analyze the incidence and risk factors for dementia and young-onset dementia (YOD) in diabetic patients in Korea using the National Health Insurance Service data.METHODS: Between January 1, 2009 and December 31, 2012, a total of 1,917,702 participants with diabetes were included and followed until the date of dementia diagnosis or until December 31, 2015. We evaluated the incidence and risk factors for all dementia, Alzheimer's disease (AD), and vascular dementia (VaD) by Cox proportional hazards analyses. We also compared the impact of risk factors on the occurrence of YOD and late-onset dementia (LOD).RESULTS: During an average of 5.1 years of follow-up, the incidence of all types of dementia, AD, or VaD was 9.5, 6.8, and 1.3/1,000 person-years, respectively, in participants with diabetes. YOD comprised 4.8% of all dementia occurrence, and the ratio of AD/VaD was 2.1 for YOD compared with 5.5 for LOD. Current smokers and subjects with lower income, plasma glucose levels, body mass index (BMI), and subjects with hypertension, dyslipidemia, vascular complications, depression, and insulin treatment developed dementia more frequently. Vascular risk factors such as smoking, hypertension, and previous cardiovascular diseases were more strongly associated with the development of VaD than AD. Low BMI and a history of stroke or depression had a stronger influence on the development of YOD than LOD.CONCLUSION: The optimal management of modifiable risk factors may be important for preventing dementia in subjects with diabetes mellitus.

ABSTRACT

BACKGROUND: Type 2 diabetes mellitus (T2DM) is associated with an increased risk for dementia. The effects of hypoglycemia on dementia are controversial. Thus, we evaluated whether hypoglycemia increases the risk for dementia in senior patients with T2DM.METHODS: We used the Korean National Health Insurance Service Senior cohort, which includes >10% of the entire senior population of South Korea. In total, 5,966 patients who had ever experienced at least one episode of hypoglycemia were matched with those who had not, using propensity score matching. The risk of dementia was assessed through a survival analysis of matched pairs.RESULTS: Patients with underlying hypoglycemic events had an increased risk for all-cause dementia, Alzheimer's dementia (AD), and vascular dementia (VaD) compared with those who had not experienced a hypoglycemic event (hazard ratio [HR], 1.254; 95% confidence interval [CI], 1.166 to 1.349; P<0.001 for all-cause dementia; HR, 1.264; 95% CI, 1.162 to 1.375; P<0.001 for AD; HR, 1.286; 95% CI, 1.110 to 1.490; P<0.001 for VaD). According to number of hypoglycemic episodes, the HRs of dementia were 1.170, 1.201, and 1.358 in patients with one hypoglycemic episode, two or three episodes, and more than three episodes, respectively. In the subgroup analysis, hypoglycemia was associated with an increased risk for dementia in both sexes with or without T2DM microvascular or macrovascular complications.CONCLUSION: Our findings suggest that patients with a history of hypoglycemia have a higher risk for dementia. This trend was similar for AD and VaD, the two most important subtypes of dementia.

ABSTRACT

BACKGROUND: Soybean food consumption has been considered as a possible way to lower incidence of cardiometabolic syndrome (CMS) among Asians. However, results from studies investigating its efficacy on CMS in Asians have been inconsistent.METHODS: We analyzed the association between soybean intake frequency and prevalence of CMS based on data from the Korea National Health and Nutrition Examination Survey 2007 to 2011. Data of 9,287 women aged 20 to 64 years were analyzed. Food frequency questionnaire was used to assess soybean food consumption frequency. General linear model and multivariable logistic regression model were used to examine the association of soybean intake quintile with CMS and its risk factors. Least square means of metabolic factors mostly showed no significant relevance except liver indexes.RESULTS: Compared to participants in the 1st quintile (<2 times/week of soybean food), odds ratios (OR) for CMS and abdominal obesity (AO) in the 4th quintile (8.5 times/week<soybean food≤17 times/week) were 0.73 (95% confidence interval [CI], 0.57 to 0.95) and 0.72 (95% CI, 0.58 to 0.90), respectively. After excluding Tofu products, ORs of CMS, AO, high blood pressure, and hypertriglyceridemia were lower than those without excluding Tofu products. However, results still did not show significant inverse linear trend across frequency quintiles.CONCLUSION: Our findings suggest that soybean intake of 8.5 to 17 times/week was inversely associated with CMS in Korean women. The relation between soybean intake >17 times/week and CMS varied depending on soybean food items.

ABSTRACT

BACKGROUND: The objective of this study was to identify a consensus on definition, diagnosis, treatment, and prognosis of frozen shoulder (FS) among shoulder specialists.METHODS: A questionnaire composed of 18 questions about FS—definition, classification, utilization of diagnostic modalities, the propriety of treatment at each stage, and prognosis—was sent to 95 shoulder specialists in Korea. Most questions (15 questions) required an answer on a 5-point analog scale (1, strongly disagree; 5, strongly agree); three questions about the propriety of treatment were binary.RESULTS: We received 71 responses (74.7%). Of the 71 respondents, 84.5% agreed with the proposed definition of FS, and 88.8% agreed that FS should be divided into primary and secondary types according to the proposed definition. Only 43.7% of the respondents agreed that FS in patients with systemic disease should be classified as secondary FS. For the diagnosis of FS, 71.9% agreed that plain radiography should be used and 64.8% agreed ultrasonography should be used. There was a high consensus on proper treatment of FS: 97.2% agreed on education, 94.4%, on the use of nonsteroidal anti-inflammatory drugs; 76.1%, on intra-articular steroid injections; and 97.2%, on stretching exercise. Among all respondents, 22.5% answered that more than 10% of the patients with FS do not respond to conservative treatment.CONCLUSIONS: The survey revealed a general consensus among shoulder specialists on the definition and treatment of FS. However, classification of FS was found controversial.

ABSTRACT

BACKGROUND: Tinea capitis is a cutaneous infection of dermatophytes and predominant in children. Although tinea capitis in Korea is controlled by oral antifungal medications and concerted public health initiatives, it's still a health issue.OBJECTIVE: To investigate changes in the epidemiological and mycological characteristics of adult patients with tinea capitis in southeastern Korea.METHODS: Using medical records from Kyungpook National University Hospital and Catholic Skin Clinic from 1989 to 2018, we retrospectively investigated the epidemiological and mycological characteristics of 266 adult patients (aged over 20) with tinea capitis.RESULTS: Among total 266 patients, 239 were KOH-positive. The annual incidence of tinea capitis ranged from 3 to 18 between 1989 and 2018. Of the total, 54 (20.30%) were male and 212 (79.70%) were female. Eighty patients (30.08%) were in their seventies, the most commonly affected age group. Of the remaining, 58 (21.80%) were in their sixties, and 41 (15.41%) in eighties. Among all, 77 (28.95%) visited the hospital in summer, 72 (27.07%) in spring, 64 (24.06%) in winter, and 53 (19.92%) in fall. Dermatophytes were cultured from 171 patients. Microsporum canis was the most common dermatophyte (42.48%), while Trichophyton rubrum was the second (15.79%). Of the 266 patients, 186 (69.92%) lived in urban areas and 80 (30.08%) in rural areas.CONCLUSION: The epidemiological and mycological characteristics of adult patients with tinea capitis were different from those of children in terms of annual incidence, sex distribution, and isolated dermatophytes. These results provide useful information for the treatment and prevention of tinea capitis.

ABSTRACT

BACKGROUND: Recently, the number of nationwide medical researches on psoriasis using the National Health Insurance Service database has been on the rise. However, identification of psoriasis using diagnostic codes alone can lead to misclassification. Accuracy of the diagnostic codes and their concordance with medical records should be validated first to identify psoriasis patients correctly.OBJECTIVE: To validate the diagnostic codes of psoriasis (International Classification of Diseases, 10th Revision L40) and to find the algorithm for the identification of psoriasis.METHODS: We collected medical records of patients who received their first diagnostic codes of psoriasis during 5 years from five hospitals. Fifteen percent of psoriasis patients were randomly selected from each hospital. We performed a validation by reviewing medical records and compared 5 algorithms to identify the best algorithm.RESULTS: Total of 538 cases were reviewed and classified as psoriasis (n=368), not psoriasis (n=159), and questionable (n=11). The most accurate algorithm was including patients with ≥1 visits with psoriasis as primary diagnostic codes and prescription of vitamin D derivatives. Its positive predictive value was 96.5% (95% confidence interval [CI], 93.9%~98.1%), which was significantly higher than those of the algorithm, including patients with ≥1 visits with psoriasis as primary diagnostic codes or including ≥1 visits with diagnostic codes of psoriasis (primary or additional) (91.0% and 69.8%). Sensitivity was 90.8% (95% CI, 87.2%~93.4%) and specificity was 92.5% (95% CI, 86.9%~95.9%).CONCLUSION: Our study demonstrates a validated algorithm to identify psoriasis, which will be useful for the nationwide population-based study of psoriasis in Korea.
