- A Case of Life-Threatening Acute Kidney Injury with Toxic Encephalopathy Caused by Dioscorea quinqueloba. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):304-6.
Some herbal medications induce acute kidney injury. The acute kidney injuries caused by herbal medications are mild and commonly treated by palliative care. A 51-years-old man who drank the juice squeezed from the raw tubers of Dioscorea quinqueloba (D. quinqueloba) was admitted with nausea, vomiting and chilling. He developed a seizure with decreased level of consciousness. He was diagnosed with acute kidney injury, which was cured by continuous venovenous hemodialfiltration. Non-detoxified D. quinqueloba can cause severe acute kidney injury with toxic encephalopathy. It is critical to inform possible adverse effects of the medicinal herbs and to implement more strict regulation of these products.
- The First Korean Case of HDR Syndrome Confirmed by Clinical and Molecular Investigation. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):300-3.
Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is a rare condition inherited as autosomal dominant trait and characterized by hypoparathyroidism, sensorineural deafness, and renal dysplasia. HDR syndrome is caused by haploinsufficiency of the GATA3 gene located on chromosome 10p15. Here, we report the case of a 32-day-old Korean male with HDR syndrome. He was presented due to repeated seizures over previous 3 days. The patient was born after 40 weeks of gestation with birth weight of 2930 g, and was the first-born baby of healthy Korean parents. Hypoparathyroidism was first noticed due to seizure. A multicystic left dysplastic kidney and vesicoureteral reflux were detected by ultrasound after birth. Auditory brainstem response (ABR) testing revealed that the patient had moderate sensorineural deafness, with hearing losses of 80 dB at the mid and higher frequencies for both ears. Echocardiography finding revealed secundum atrial septal deftect. Based on biochemical results and clinical findings, a presumptive diagnosis of HDR syndrome was made. GATA3 mutation analysis identified a heterozygous deletion, c.153del (p.Phe51Leufs*144) in exon 1 causing a frameshift mutation, which is a novel de novo mutation. Therefore, we suggest that HDR syndrome should be considered in the differential diagnosis in symptomatic or asymptomatic patients with hypoparathyroidism, and that renal ultrasound or ABR testing be performed to prevent a missed diagnosis. This is the first report on Korean patient with confirmed HDR syndrome with novel mutation.
- Efficacy of team-based financial incentives for smoking cessation in the workplace. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):295-9.
Worksite smoking cessation programs offer accessibility of the target population, availability of occupational health support, and the potential for peer pressure and peer support. The purpose of this study was to identify the efficacy of the financial incentives given to various teams in the workplace. St. Paul's Hospital's employees were enrolled. Each team of employees consisted of smoking participants and non-smoking fellow workers from the same department. The financial incentive of 50000 won (about $45) was rewarded to the team for each successful participant-not to individual members-after the first week and then after one month. If the smokers in the team remained abstinent for a longer time period, the team was given an incentive of 100000 won for each successful participant after 3 and 6 months. A total 28 smoking participants and 6 teams were enrolled. Self-reported abstinence rates validated by urinary cotinine test at 3, 6, and 12 months after the initial cessation were 61%, 54%, and 50%, respectively. Smokers with high nicotine dependence scores or those who began participation 1 month after enrollment initiation had a lower abstinence rate at 3 months, but not at 6 and 12 months. Participants who succeeded at smoking cessation at 12 months were more likely to be older and have a longer smoking duration history. The financial incentives given to teams could be promising and effective to improve long-term rates of smoking cessation. This approach could use peer pressure and peer support in the workplace over a longer period.
- Bacteroides faecis and Bacteroides intestinalis Recovered from Clinical Specimens of Human Intestinal Origin. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):292-4.
We report three cases of recently named Bacteroides spp. isolates, two B. faecis isolates and one B. intestinalis isolate from clinical specimens of inpatients at a Korean tertiary-care hospital in 2011. All isolates were susceptible to piperacillin-tazobactam, imipenem, meropenem, chloramphenicol, and metronidazole.
- Predictors of response to corticosteroid treatment in patients with early acute respiratory distress syndrome: results of a pilot study. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):287-91.
Prospective observational cohort study was performed to evaluate predictors for responsiveness to corticosteroid treatment in patients with acute respiratory distress syndrome (ARDS). Over the study period, a total of 20 patients (male 70%, median age 69) with ARDS were treated with corticosteroid within 72 h after intubation. The median lung injury score (LIS) and partial pressure of arterial oxygen (PaO₂)/fraction of inspired oxygen (FiO₂) ratios (PF ratios) were 3.0 (interquartile range, 2.7-3.0) and 146.6 (119.9-179.4), respectively. The median levels of triggering receptor expressed on myeloid cells (TREM-1) and procollagen peptide type III in bronchoalveolar lavage (BAL) fluid were 349.3 (225.6-634.9) pg/mL and 19.6 (11.7-39.7) pg/mL, respectively. After 7 days of corticosteroid treatment, 10 (50%) patients showed response to the treatment (successful extubation in 7 and 1-point or more reduction in LIS in 3). Compared to non-responders, responders had higher initial PF ratios (170.5 vs. 127.2, p=0.023), lower level of TREM-1 in BAL fluid (313.6 pg/mL vs. 520.5 pg/mL, p=0.029), and greater reduction in LIS at 3 days (-1 vs. 0, p<0.001). In conclusion, PF ratios and TREM-1 level in BAL fluid at baseline, and reduction in LIS at day 3 after the treatment were associated with the response to prolonged corticosteroid treatment (ClinicalTrials.gov Identifier: NCT01093287).
- Biologic response of degenerative living human nucleus pulposus cells to treatment with cytokines. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):277-86.
To investigate the molecular responses of various genes and proteins related to disc degeneration upon treatment with cytokines that affect disc-cell proliferation and phenotype in living human intervertebral discs (IVDs). Responsiveness to these cytokines according to the degree of disc degeneration was also evaluated.The disc specimens were classified into two groups: group 1 (6 patients) showed mild degeneration of IVDs and group 2 (6 patients) exhibited severe degeneration of IVDs. Gene expression was analyzed after treatment with four cytokines: recombinant human bone morphogenic protein (rhBMP-2), transforming growth factor-β (TGF-β), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α). Molecular responses were assessed after exposure of cells from the IVD specimens to these cytokines via real-time polymerase chain reaction and immunofluorescence staining.mRNA gene expression was significantly greater for aggrecan, type I collagen, type II collagen, alkaline phosphatase, osteocalcin, and Sox9 in group 1 than mRNA gene expression in group 2, when the samples were not treated with cytokines. Analysis of mRNA levels for these molecules after morphogen treatment revealed significant increases in both groups, which were much higher in group 1 than in group 2. The average number of IVD cells that were immunofluorescence stained positive for alkaline phosphatase increased after treatment with rhBMP-2 and TGF-β in group 1.The biologic responsiveness to treatment of rhBMP-2, TGF-β, TNF-α, and IL-1β in the degenerative living human IVD can be different according to the degree of degeneration of the IVD.
- Reliability and Validity of the Upper Limb Physician's Rating Scale in Children with Cerebral Palsy. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):271-6.
The Upper Limb Physician's Rating Scale (ULPRS) is a tool that assesses movement quality of the upper limbs. It is used as an outcome measure after botulinum toxin type A injection in children with cerebral palsy (CP). This study aimed to investigate the reliability and validity of the ULPRS in children with spastic CP.Thirty children with spastic CP (M:F=17:13) aged 5 to 13 years old were recruited. The ULPRS was scored based on recorded videotapes by four physicians on two separate occasions. The Melbourne Assessment of Unilateral Upper Limb Function (MUUL) was scored by an occupational therapist. Intraclass correlation coefficients (ICCs), 95% confidence intervals and weighted kappa statistics were calculated for the scores of ULPRS to obtain interrater and intrarater reliability. The relationship between ULPRS and MUUL was assessed using Pearson correlation coefficients.The ICCs for the total ULPRS scores were 0.94 between raters and 0.99 to 1.00 within raters. The weighted kappa statistics for subitem scores for the ULPRS ranged from 0.67 to 1.00 within raters and from 0.46 to 0.86 between raters. The relationship between ULPRS and MUUL was strong (Pearson correlation coefficient=0.751; p<0.05).The results demonstrated the high reliability of the total ULPRS score within and between raters. A significant concurrent validity between ULPRS and MUUL also supports the clinical utility of the ULPRS as an outcome measure of spastic upper limb in children with CP.
- Characteristics of inpatient care and rehabilitation for acute first-ever stroke patients. [Journal Article]
- Yonsei Med J 2015 Jan 1; 56(1):262-70.
The purpose of this study was to analyze the status of inpatient care for acute first-ever stroke at three general hospitals in Korea to provide basic data and useful information on the development of comprehensive and systematic rehabilitation care for stroke patients.This study conducted a retrospective complete enumeration survey of all acute first-ever stroke patients admitted to three distinct general hospitals for 2 years by reviewing medical records. Both ischemic and hemorrhagic strokes were included. Survey items included demographic data, risk factors, stroke type, state of rehabilitation treatment, discharge destination, and functional status at discharge.A total of 2159 patients were reviewed. The mean age was 61.5±14.4 years and the ratio of males to females was 1.23:1. Proportion of ischemic stroke comprised 54.9% and hemorrhagic stroke 45.1%. Early hospital mortality rate was 8.1%. Among these patients, 27.9% received rehabilitation consultation and 22.9% underwent inpatient rehabilitation treatment. The mean period from admission to rehabilitation consultation was 14.5 days. Only 12.9% of patients were transferred to a rehabilitation department and the mean period from onset to transfer was 23.4 days. Improvements in functional status were observed in the patients who had received inpatient rehabilitation treatment after acute stroke management.Our analysis revealed that a relatively small portion of patients who suffered from an acute first-ever stroke received rehabilitation consultation and inpatient rehabilitation treatment. Thus, applying standardized clinical practice guidelines for post-acute rehabilitation care is needed to provide more effective and efficient rehabilitation services to patients with stroke.
