PURPOSE: This study was conducted to explore clinical nurses' experience of positive organizational culture in order to provide data for effective strategies of acquisition and retention of competent nurses. METHODS: In this qualitative study, interviews with four focus groups of four to six nurses, 19 in total, were held. Compositional factors in groups included clinical experience, age, work place, and position. Interviews proceeded until data were saturated. RESULTS: Fifteen sub-themes, categorized into six themes, emerged. Positive organizational culture themes included "Helping nurses to be organization members", "Allowing nurses to communicate with one another", "Helping nurses take an initiative to lead organization", "Having competent leader take charge of organization", "Enabling nurses to achieve organizational changes", and "Leading nurses to accomplish organizational performance." CONCLUSION: Results indicate that positive organizational culture is related to increases in occupational satisfaction and decreases in turnover through supportive organizational culture which makes it possible to reinvest expenses required for training new members to promoting quality growth in the organization and the prestige of professional nurses. In order to improve occupational satisfaction and sustained growth in nurses, it is necessary to provide nurses with positive work environments and require members to make active efforts leading to strategic changes.

Primary central nervous system lymphoma (PCNSL) is a rare tumor that accounts for less than 2% of all cerebral neoplasms. A 72-year-old man had been suffering from recurrent cranial nerve palsies for several years. His condition improved with steroid treatment, but then eventually worsened; he developed encephalopathic symptoms, quadriparesis, axonal neuropathy, and skin lesions. He was eventually diagnosed with PCNSL following an examination of skin and sural nerve biopsy samples. Biopsy of skin lesions or nerves should be considered for the accurate and early diagnosis of PCNSL.

BACKGROUND: The etiology of transient global amnesia (TGA) is uncertain. Recent studies have demonstrated a high signal intensity on diffusion MRI in TGA patients. In this study we reviewed and compared the use of electroencephalography (EEG) and diffusion-weighted imaging (DWI) in TGA in order to determine their sensitivity and to reveal clues about the etiology of this condition. METHODS: Twenty patients (7 males and 13 females; aged 58.0+/-12.1 years, mean+/-SD) who had been diagnosed with TGA at Dongguk University International Hospital within a 2-year period (2007 and 2008) were included in the study. All patients underwent EEG and DWI. RESULTS: The EEG of 12 of the 20 patients (60.0%) exhibited abnormalities; all 12 exhibited slowing on either the left side (n=6) or bilaterally (n=6). Spikes or sharp waves were detected in two patients. DWI revealed unilateral high signal intensities in the hippocampus of eight patients; five of these patients had left hippocampal lesions, and the other three had right hippocampal lesions. Four patients with a unilateral DWI lesion exhibited bilateral EEG abnormalities, and six patients exhibited only EEG abnormalities (without DWI abnormalities). Three patients had a high-signal-intensity lesion on DWI without EEG abnormalities. Five patients had normal EEG and DWI results. Interestingly, no patient had EEG abnormalities confined to the right temporal area. CONCLUSIONS: These findings suggest that left temporal dysfunction is important for the development of TGA. EEG might be complementary to DWI in TGA investigations, and may be superior at illustrating the associated memory dysfunction.

BACKGROUND AND PURPOSE: Little is known about the relationships between provoking risk factors, prognosis, and optimal duration of anticoagulation in patients with cerebral venous thrombosis (CVT), especially in Asians. We aimed to investigate whether the prognosis and required duration of anticoagulation in CVT patients differ according to the provoking risk factors. METHODS: Prospectively recorded data from a tertiary medical center in South Korea were retrospectively reviewed. CVTs were categorized into three groups: unprovoked, those with possibly resolved provoking factors (PR), and those with persistent provoking factors (PP). The baseline characteristics, treatment, and prognosis of patients in these three groups were analyzed. RESULTS: From 2000 to 2015, 61 patients presented with CVT: 19 (31.1%) unprovoked, 11 (18.0%) with PR, and 31 (50.9%) with PP. The patients in our cohort had a slight female predominance and lower frequency of oral contraceptive use compared to Western cohorts. Median follow-up and duration of anticoagulation were 35 and 8 months, respectively. Despite the similarities in baseline characteristics, deaths (n=3; P=0.256) and recurrences (n=7; P=0.020) were observed only in the PP group. The median intervals to death and recurrence were 9 and 13 months, respectively. Death was associated with underlying disease activity, not with CVT progression. Recurrences in the PP group were associated with lack of anticoagulation (P=0.012). CONCLUSIONS: Although the prognosis of CVT is generally benign in Koreans, recurrence and death were observed in patients with persistent risk factors, suggesting their need for long-term treatment with anticoagulants.
