Paraneoplastic pemphigus is a rare, life-threatening disorder associated with an underlying neoplasm, which presents with painful stomatitis and polymorphous skin lesions. Successful diagnosis of paraneoplastic pemphigus can lead to the diagnosis and treatment of the underlying malignancy.However, involvement of the respiratory system is typically unresponsive to treatment. Herein, we report the case of a 44-year-old female diagnosed with paraneoplastic pemphigus with underlying follicular lymphoma treated with a chemotherapy regimen including rituximab. Her skin lesions and underlying lymphoma responded to treatment, but bronchiolitis obliterans continued to progress and resulted in fatal respiratory failure.

BACKGROUND: Quality-adjusted life expectancy (QALE) means life expectancy (LE) reflecting health-related quality of life and is one of the indicators of healthy LE. We determined the trends in QALE in Korea by age, gender, educational level, and subregion from 2005 to 2013. METHODS: We applied the Sullivan method to estimate QALE. We calculated QALE from 2005 to 2013 by gender and QALE for 2005 and 2010 by educational level at the national level. Furthermore, we estimated QALE for 2005, 2008, and 2011 by subregion according to metropolitan and provincial levels. RESULTS: Population health in Korea measured by LE and QALE at age 0 increased steadily from 2005 to 2013. Annual percent changes of LE and QALE in men were 0.52 and 0.73, respectively (P value < 0.05), and those in women were 0.47 and 0.71, respectively (P value < 0.05). Koreans with a higher educational level had longer LE and QALE than those with a lower educational level, but the differences in LE and QALE according to educational level narrowed from 2005 to 2010. The LE and QALE at age 0 for each of the 16 subnational regions in 2011 increased compared to 2005, but there was still a difference of up to 4.57 years in QALE between subnational regions. CONCLUSION We showed that QALE could be easily calculated and be an appropriate measure for tracking the overall population's health level. The results from this study are expected to aid the Ministry of Health of Republic of Korea in setting up a goal for the National Health Plan.

OBJECTIVES: We performed a systematic review to assess and aggregate the available evidence on the frequency, expected effects, obstacles, and facilitators of disclosure of patient safety incidents (DPSI). METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for this systematic review and searched PubMed, Scopus, and the Cochrane Library for English articles published between 1990 and 2014. Two authors independently conducted the title screening and abstract review. Ninety-nine articles were selected for full-text reviews. One author extracted the data and another verified them. RESULTS: There was considerable variation in the reported frequency of DPSI among medical professionals. The main expected effects of DPSI were decreased intention of the general public to file medical lawsuits and punish medical professionals, increased credibility of medical professionals, increased intention of patients to revisit and recommend physicians or hospitals, higher ratings of quality of care, and alleviation of feelings of guilt among medical professionals. The obstacles to DPSI were fear of medical lawsuits and punishment, fear of a damaged professional reputation among colleagues and patients, diminished patient trust, the complexity of the situation, and the absence of a patient safety culture. However, the factors facilitating DPSI included the creation of a safe environment for reporting patient safety incidents, as well as guidelines and education for DPSI. CONCLUSIONS: The reported frequency of the experience of the general public with DPSI was somewhat lower than the reported frequency of DPSI among medical professionals. Although we identified various expected effects of DPSI, more empirical evidence from real cases is required.

BACKGROUND: This study assessed the perceptions of healthcare staff of the health risks of exposure to electromagnetic fields (EMF). METHODS: In total, 328 healthcare workers (e.g., physicians, nurses, medical students, and paramedics) completed a self-administered questionnaire. The questionnaire assessed the following: risk perceptions of 17 environmental factors as potential health threats; EMF sources; information for the potential risks of EMF; and thoughts on how to protect the public from potential EMF-related health risks. RESULTS: Of the included environmental factors, high-tension power lines and mobile phone handsets were ranked as the second and fourth lowest perceived risk, respectively. Approximately 60% of respondents were concerned about the potential health risks of EMF and dissatisfied with the information they received. The main reason for dissatisfaction was insufficient information. The most frequently cited action was that the government should review the available scientific evidence on potential EMF-related health risks. CONCLUSIONS: Having scientific basis through well-designed researches and providing accurate information to the public on the potential health risks of EMF will be important in the future.

Background: The STOP-BANG questionnaire is a simple screening tool with high sensitivity for the detection of severe obstructive sleep apnea (OSA). Predicting airway obstruction would allow the safe management of sedative patients to prevent intraoperative hypoxia. This study was designed to check the correlation between the STOP-BANG score and oxygen saturation (SpO2) during sedation and confirm the availability of the STOP-BANG questionnaire as a preoperative exam for predicting the incidence of hypoxia in sedative patient management. Methods: This study included 56 patients who received spinal anesthesia. The pre-anesthesia evaluation was conducted using the STOP-Bang questionnaire. The patients were under spinal anesthesia with an average block level of T10. Dexmedetomidine was infused with a loading dose of 1 μg/kg over 10 min and a maintenance dose of 0.5 μg/kg/h until the end of the procedure. The SpO2 of the patients was recorded every 5 min. Results: The STOP-Bang score was negatively correlated with the lowest SpO2 (coefficient = –0.774, 95% confidence interval [CI]: –0.855 to –0.649, standard error [SE] = 0.054, P < 0.001). The item of “observed apnea” was the most correlated one with hypoxic events (odds ratio = 6.00, 95% CI: 1.086 to 33.145). Conclusions The STOP-BANG score was significantly correlated with the lowest SpO2 during spinal anesthesia, which enabled the prediction of meaningful hypoxia before it occurred in the sedated patients.

Gerstmann's syndrome, assigned to a lesion of the dominant parietal lobe, is a neurological disorder characterized by acalculia, agraphia, right-left disorientation and finger agnosia. Some studies report that these symptoms are also shown in other brain lesions. We report two patients who presented with this tetrad of symptoms in initial assessment. Their Brain MRI images both showed lesion of left frontal lobe. Over time, these symptoms became better but some still remained in last assessment. Accordingly, we suggest that a left frontal lesion cause Gerstmann's syndrome.

BACKGROUND/AIMS: Conventional triple therapy (CT) for Helicobacter pylori infection fails in up to one-third of patients. Sequential therapy (ST) seem be more effective than CT in other countries. However, there is no systemic literature review that directly compares CT and ST in Korea. The aim of this study was to compare ST with CT for H. pylori infection in Korea. METHODS: Six randomized, prospective controlled trials were used to compare 10-day ST and 7- to 14-day CT in treatment-naive patients with documented H. pylori infection in Korea. Pooled eradication rates and OR with 95% CI were calculated. RESULTS: The intention-to-treat eradication rates of H. pylori involving 1,529 patients were 79.7% (95% CI, 76.8-82.5%) for ST (n=754) and 68.1% (95% CI, 64.8-71.4%) for CT (n=775) (OR, 1.838; p<0.001). The per-protocol eradication rate of H. pylori involving 1,366 patients was 86.4% (95% CI, 83.3-88.5%) for ST (n=682) and 76.0% (95% CI, 72.8-79.2%) for CT (n=684) (OR, 1.974; p<0.001). CONCLUSIONS: Ten-day ST was superior to CT in terms of eradicating H. pylori infection. Therefore, ST should be considered as a first-line therapy in Korea. However, ST did not achieve a sufficient eradication rate. More effective therapy should be developed.

OBJECTIVE: We investigated the differences of functions, activity of daily living (ADL), and quality of life (QoL) according to hand dominance in hemiplegic stroke patients. METHOD: The participants were diagnosed as stroke at P hospital. 370 participants (356 right dominant hand, 14 left dominant hand) were right hemisphere stroke, and 258 participants (248 right dominant hand, 10 left dominant hand) were left hemisphere stroke. To compensate the differences of imbalance in the number of participants' hand dominance, we performed the propensity score matching analysis. We analyzed the variation of stroke severity, disability, motor, mobility, cognition and language functions from 7 days until 3 months after onset using analysis of covariance (ANCOVA). Then, we performed independent t-test to compare hand dexterity, ADL, mood, subjective health condition and QoL of participants according to the hand dominance and the affected hemisphere. RESULTS: All groups showed increased functions during 3 months without statistically significant differences according to hand dominance in both right and left hemisphere stroke patients. In addition, ADL, mood, subjective health condition and QoL were also not significantly different depending on hand dominance in the right and left hemisphere. CONCLUSION: The difference of hand dominance did not influence stroke severity, disability, motor, mobility, cognition or language functions. It also didn't correlate with ADLs, mood or QoL.
