BACKGROUND AND OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) has been well controlled with otolith reposition therapy. Posterior canal is known as the most common site of BPPV. The purpose of this study was to study the therapeutic result of reposition therapy in posterior canal BPPV, to investigate the unusual cases such as recurred cases and type changed cases during the reposition maneuver, and to figure out the therapeutic strategy. MATERIALS AND METHODS: One hundred and ten patients diagnosed posterior canal BPPV were included in this study. Epley maneuver was performed once a day until nystagmus disappeared. We analyzed the number of treatment, changing type, recurrence and the relationship between recurrence and age or sex of patients. RESULT: All cases except 2 were recovered by Epley maneuver. In 11 cases, the type of disease was changed, and the treatment of these cases were changed according to new type and origin. Overall recurrence rate was 15%, and they were completely treated with reposition therapy. There was no correlation between recurrence and age, sex of patients. CONCLUSION: All most cases were cured with Epley maneuver. The type of the disease was possibly changeable. Recurrence rate was relative high, and close follow up was required.

PURPOSE: This study aimed to identify the factors influencing human papillomavirus (HPV) vaccination adoption stages using the Precaution Adoption Process model. METHODS: A total of 173 female university students from B metropolitan city participated. Demographics, factors contributing to action, knowledge, health beliefs, and self-efficacy related to the HPV vaccination were measured. The collected data were analyzed using descriptive statistics and multiple logistic regression analysis using SPSS for Windows version 21.0. RESULTS: Factors that contributed to the transition from the unaware and unengaged stages to the undecided about action stage included age, economic status, experience of recommendation from doctors, perceived severity of cervical cancer, and perceived barriers. Factors that contributed to the transition from the undecided about action stage to the deciding to act stage were perceived benefit and self-efficacy of the HPV vaccination. Factors that contributed to the transition from the deciding to act stage to the acting and maintenance stages were experience of recommendation from doctors and perceived severity of cervical cancer. CONCLUSION: These results suggest that aggressive HPV vaccination campaigns increase awareness. Further studies should develop tailored strategies for promoting HPV vaccination that emphasize health beliefs and self-efficacy.

BACKGROUND AND OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) is a common vestibular disease. The theories of can-alolthiasis and cupulolithisis of posterior semicircular canal are commonly accepted in BPPV. Recently, not only posterior canal but also lateral canal BPPV were reported. The purposes of this study are to analyze the result of lateral canal BPPV treatment and to introduce effective schedule of reposition maneuvers and follow up. MATERIALS AND METHODS: Sixty two patients who were diagnosed as lateral semicircular canal BPPV were included in this study. Supine head turning test was done and eye movement was documented with videonystagmography. In the canalolithiasis type, barbecue rotation maneuver was performed and in the cupulolithiasis type, cupulolith reposition maneuver was performed. In each type of BPPV, we analyzed the number of treatment until nystagmus was disappeared, recurrence rate and relationship between recurrence and age, sex of patients. RESULTS: Canalolithiasis type was 55% and cupulolithiasis type was 37%. Eight percents of patients showed combined type. All except 2 cases (congenital malformation) were healed by the reposition maneuver. Vertigo recurred in about 30% of patients, and they were retreated with the reposition maneuver. There was no correlation between recurrence and age, sex of patients. CONCLUSION: In lateral semicircular canal BPPV, the reposition maneuver was a effective treatment method. The reposition maneuver was recommended to perform continuously once a day until nystagmus disappeared. Because recurrence rate was about 30%, continuous follow-up was needed.

BACKGROUND AND OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) has been well controlled with otolith reposition maneuver. The purpose of this study was to investigate the incidence of various forms of BPPVs such as type change during the reposition maneuver, combined type and recurred cases, to study the therapeutic result of physical therapy in various forms of BPPVs, and to figure out the therapeutic strategy. MATERIALS AND METHOD: One hundred and twenty-seven patients who were diagnosed with BPPV were included in this study. Reposition maneuver was performed once a day until nystagmus disappeared. In the case of posterior canal BPPV, Epley maneuver was performed. In the case of lateral canal BPPV, barbecue rotation maneuver was performed in canalolithiasis type, and cupulolith reposition maneuver in cupulolithiasis type. In each type of BPPV, we analyzed the number of treatment, recurrence, changing type, and the relationship between recurrence and age or sex of patients. RESULTS: Posterior canal origin was more common than lateral canal origin. All cases except 2 were recovered by reposition maneuver. In 8 cases, the type of disease was changed, and the treatment of these cases were changed according to new type and origin. Overall recurrence rate was 14%, and they were completely treated with reposition maneuver. There was no correlation between recurrence and origin, type, age or sex of patients. CONCLUSION: Patients showed various origin, type and recurrence. Type of the disease was possibly changeable. Almost all the cases were cured with suitable reposition maneuver. Recurrence rate was relatively high, and the close follow up is required.

BACKGROUND: Medical staff members are concentrated in the intensive care unit (ICU), and medical residents are essentially needed to operate the ICU. However, the recent trend has been to restrict resident working hours. This restriction may lead to a shortage of ICU staff, and there is a chance that regional academic hospitals will face running ICUs without residents in the near future. METHODS: We performed a retrospective observational study (intensivist crossover design) of medical patients who were transferred to two ICUs from general wards between September 2017 and February 2019 at one academic hospital. We compared the ICU outcomes according to the ICU type (ICU with resident management under high-intensity intensivist staffing vs. ICU with direct management by intensivists without residents). RESULTS: Of 314 enrolled patients, 70 were primarily managed by residents, and 244 were directly managed by intensivists. The latter patients showed better ICU mortality (29.9% vs. 42.9%, P = 0.042), lower cardiopulmonary resuscitation (CPR) (10.2% vs. 21.4%, P = 0.013), lower continuous renal replacement therapy (CRRT) (24.2% vs. 40.0%, P = 0.009), and more advanced care planning decisions before death (87.3% vs. 66.7%, P = 0.013) than the former patients. The better ICU mortality (hazard ratio, 1.641; P = 0.035), lower CPR (odds ratio [OR], 2.891; P = 0.009), lower CRRT (OR, 2.602; P = 0.005), and more advanced care planning decisions before death (OR, 4.978; P = 0.007) were also associated with intensivist direct management in the multivariate cox and logistic regression analysis. CONCLUSION Intensivist direct management might be associated with better ICU outcomes than resident management under the supervision of an intensivist. Further large-scale prospective randomized trials are required to draw a definitive conclusion.

BACKGROUND: Usually, high-flow nasal cannula (HFNC) therapy is indicated for de novo acute hypoxemic respiratory failure (AHRF). Although only a few researches have examined the effectiveness of HFNC therapy for respiratory failure with hypercapnia, this therapy is often performed under such conditions for various reasons. We investigated the effectiveness of HFNC therapy for AHRF patients with hypercapnia compared to those without hypercapnia. METHODS: All consecutive patients receiving HFNC therapy between January 2012 and June 2018 at a university hospital were enrolled and classified into nonhypercapnic and hypercapnic groups. We compared the outcomes of both groups and adjusted the outcomes with propensity score matching. RESULTS: A total of 862 patients were enrolled, of which 202 were included in the hypercapnic group. HFNC weaning success rates were higher, and intensive care unit (ICU) and hospital mortality was lower in the hypercapnic group than in the nonhypercapnic group (all P < 0.05). However, no statistical differences in HFNC weaning success (adjusted P = 0.623, matched P = 0.593), ICU mortality (adjusted P = 0.463, matched P = 0.195), and hospital mortality (adjusted P = 0.602, matched P = 0.579) were noted from the propensity-adjusted and propensity-matched analyses. Additionally, in the propensity score-matched subgroup analysis (according to chronic lung diseases and causes of HFNC application), there was also no significant difference in outcomes between the two groups. CONCLUSION In AHRF with underlying conditions, HFNC therapy might be helpful for patients with hypercapnia. Large prospective and randomized controlled trials are required for firm conclusions.

PURPOSE: The aim of this study was to describe the experience of teaching emergency management and cardiopulmonary resuscitation to medical students in Busan. METHODS: Study participants were 59 medical students in Busan. An eight-day curriculum in the emergency management and cardiopulmonary resuscitation was developed. They completed all class sessions and two drill/practical examinations taught by our interdisciplinary team from July 21 through 30, 2003. Each class is approximately 2 hours and reading assignments are given at the end of each class. Also included are practical, table-top and team-building exercises. The participants completed self-reported questionnaires for the education. RESULTS: About establishment and environment of the education, respondents answered with `very good' were 14%. About overall theoretical lecture, respondents answered with `very helpful' were lower than 40%. Especially, favorable evaluation for the medical lectures was lower than that of other lectures. Students generally enjoyed their emergency medicine experience as it is often their first opportunity to assume primary responsibility for patient care. About overall practices, respondents answered with 'very helpful' were higher than 60%. CONCLUSION: The authors found that medical students prefer opportunities to hone procedural skills than to hear theoretical lectures. Also, medical students are welcome to hear theoretical lectures that consists of emergency management related contents, not academically medical contents. This curriculum should be tailored to fulfill learner's requirements.

Six hundred fifty-one metacarpal bones of Koreans were studied for variations in articular and non-articular surface and the number, position and direction of the diaphyseal nutrient foramina. The facets for articulation of the metacarpal bone with one another showed very frequent variations from the standard text-book description. The number and the sites of entry of the diaphyseal nutrient foramina also showed considerable variations. These findings show no apparent racial difference in variations of metacarpal bones between a Korean and an Indian.
