The survival rate of commotio cordis is low, and there is often associated neurological disability if return of spontaneous circulation (ROSC) can be achieved. We report a case of commotio cordis treated with therapeutic hypothermia (TH) that demonstrated a favorable outcome. A 16-year-old female was transferred to our emergency department (ED) for collapse after being struck in the chest with a dodgeball. She has no history of heart problems. She was brought to our ED with pulseless ventricular tachycardia (VT), and ROSC was achieved with defibrillation. She was comatose at our ED and was treated with TH at a target temperature of 33degrees C for 24 hours. After transfer to the intensive care unit, pulseless VT occurred, and defibrillation was performed twice. She recovered to baseline neurologic status with the exception of some memory difficulties.

BACKGROUND/AIMS: Recently, a number of studies have reported that the gut microbiota could contribute to human conditions, including obesity, inflammation, cancer development, and behavior. We hypothesized that the composition and distribution of gut microbiota are different according to stool frequency, and attempted to identify the association between gut microbiota and stool frequency. METHODS: We collected fecal samples from healthy individuals divided into 3 groups according to stool frequency: group 1, a small number of defecation (≤2 times/wk); group 2, normal defecation (1 time/day or 1 time/2 day); and group 3, a large number of defecation (≥2–3 times/day). We evaluated the composition and distribution of the gut microbiota in each group via 16S rRNA-based taxonomic profiling of the fecal samples. RESULTS: Fecal samples were collected from a total of 60 individuals (31 men and 29 women, aged 34.1±5.88 years), and each group comprised 20 individuals. The microbial richness of group 1 was significantly higher than that of group 3 and tended to decrease with increasing number of defecation (P<0.05). The biological community composition was fairly different according to the number of defecation, and Bacteroidetes to Firmicutes ratio was higher in group 1 than in the other groups. Moreover, we found specific strains at the family and genus levels in groups 1 and 3. CONCLUSIONS: Bacteroidetes to Firmicutes ratio and the abundance of Bifidobacterium were different according to the stool frequency, and specific bacteria were identified in the subjects with large and small numbers of defecation, respectively. These findings suggest that stool frequency might be associated with the richness and community composition of the gut microbiota.

Sulfoxaflor is the first insecticide belonging to the sulfoximine class and is efficient against sap-feeding insects that are resistant to other insecticides. Sulfoxaflor acts as a neurotoxin to the central nervous system of insects compared with very low toxicity to mammalian. We report on a case of a 67-year-old male who ingested insecticide and received conservative treatment for mild metabolic acidosis and gastrointestinal symptoms.

OBJECTIVES: The deficit of recognition memory has been found as one of the common neurocognitive impairments in patients with schizophrenia. In addition, they were reported to fail to enhance the memory about emotional stimuli. Previous studies have shown that bilateral eye movements enhance the memory retrieval. Therefore, this study was conducted in order to investigate the memory enhancement of bilaterally alternating eye movements in schizophrenic patients. METHODS: Twenty one patients with schizophrenia participated in this study. The participants learned faces (angry or neutral faces), and then performed a recognition memory task in relation to the faces after bilateral eye movements and central fixation. Recognition accuracy, response bias, and mean response time to hits were compared and analysed. Two-way repeated measure analysis of variance was performed for statistical analysis. RESULTS: There was a significant effect of bilateral eye movements condition in mean response time(F=5.812, p<0.05) and response bias(F=10.366, p<0.01). Statistically significant interaction effects were not observed between eye movement condition and face emotion type. CONCLUSIONS: Irrespective of the emotional difference of facial stimuli, recognition memory processing was more enhanced after bilateral eye movements in patients with schizophrenia. Further study will be needed to investigate the underlying neural mechanism of bilateral eye movements-induced memory enhancement in patients with schizophrenia.

BACKGROUND: This study quantitatively and qualitatively analyzed the characteristics and trends of papers published in the Journal of the Korean Geriatrics Society. METHODS: Original articles, case reports, review articles published from 2006 to 2013 were retrospectively examined. All of the article research topics, paper-specific corresponding author's affiliations and number of authors were investigated. Original articles were separated and grouped according to research designs. Using the Korean Citation Index, impact factor of this journal was examined and compared with four related journals. RESULTS: Of the 276 articles analyzed, 159 (57.6%) were original articles, 145 (91.2%) were analytic studies, and 36 (22.6%) were experimental studies. The proportion of original articles accounted for about 60% until 2007 but decreased to 41.0% in 2013. By clinical study topics, 37 studies (13.4%) addressed the understanding of geriatric diseases and 45 studies (16.3%) were focused on nervous system diseases. The median number of authors for the 276 studies was 6. Internal medicine accounted for the largest proportion of corresponding author's affiliation (109 studies, 39.5%) studies. Impact factor of the journal increased from 0.05 (4th position) in 2009 to 0.48 (3rd position) in 2011. CONCLUSION: Articles published in the Journal of the Korean Geriatrics Society increasingly included experimental studies based on evidence-centered medicine, with the proportion of original articles decreasing. The impact factor increased annually along with the journal ranking, compared with other journals. Journal of the Korean Geriatrics Society is judged to be qualitatively improving.

PURPOSE: This study was conducted to assess the satisfaction, and factors influencing the satisfaction, of patients and guardians with the internal environment and safety of ambulances in Korea. METHODS: Participants were patients and guardians who were transported by public emergency medical service ambulance to an emergency medical center in June 2015. Data were collected using self-administered questionnaires. The degree of satisfaction with the ambulance was categorized as satisfaction (Likert scale 4 or 5) or dissatisfaction (Likert scale 1 or 2). The questionnaires comprised 3 categories: 1) demographics, 2) internal environment (space, light, temperature, humidity, soundproof, and odor), and 3) safety (vibration, leaning of body, and falling objects). RESULTS: Among 84 cases, 80.5% of patients and 83.7% of guardians gave positive responses regarding general satisfaction with the internal environment of the ambulance, but these percentages were lower regarding adequacy of space and light. Four factors had a statistically significantly influence on the degree of satisfaction: 1) sex of guardian regarding adequacy of space, 2) number of guardians regarding general satisfaction, 3) severity of patient regarding guardian's satisfaction with space, 4) diagnosis of patient (trauma vs non-trauma) regarding vibration during transport (all p<0.05). CONCLUSION: Overall, patients and guardians were satisfied with the internal environment and safety of ambulances except for adequacy of space and light.

This is a report of a 58-year-old female with Cushing syndrome who underwent posterior lumbar fusion and lost both her vision completely. She was diagnosed with posterior ischemic optic neuropathy. Cushingoid features such as buffalo hump and central obesity might have attributed in triggering posterior ischemic optic neuropathy. When laid prone for surgery, perioperative high abdominal pressure causes venous hypertension leading to increase amount of blood loss. To compensate, infusion of large quantities of intravenous fluids is necessary which leads to hemodilution which decreases ocular perfusion pressure. Hypercoagulability of Cushing syndrome is also potentially a risk factor of this condition which increases the incidence of venous thromboembolism. For there is no known effective treatment for posterior ischemic optic neuropathy, means to prevent this complication must be strategically reviewed. When performing long spine surgery on patient who has Cushing syndrome or cushingoid features, caution must be taken to avoid this devastating complication.

OBJECTIVE: The laboratory biomarkers used to diagnose spinal infection include white blood cell (WBC) counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Recently, procalcitonin (PCT) has been used as a biomarker to distinguish between bacterial infection and non-bacterial infection. We aimed to compare the changes of conventional biomarker and PCT in patients with spinal infection before and after antibiotic treatment. METHODS: ESR, CRP, WBC counts, and PCT were measured in 29 patients diagnosed with pyogenic spinal infection at our hospital between May 2016 and December 2018 prior to antibiotic administration. After antibiotic administration, the values were followed up for 4 weeks at 1-week intervals. RESULTS: A total of 29 patients were enrolled, with a mean age of 67.8 years, consisting of 16 men and 13 women. Twenty-five patients had lumbar infections, and 2 each had cervical and thoracic infections. The mean ESR, CRP, PCT, and WBCs decreased at week 4 of antibiotic treatment compared to their baseline values. CRP and WBCs were significantly decreased after 4 weeks of treatment compared to before treatment. The mean ESR and PCT was not statistically significant compared to pretreatment and after antibiotic treatment (p-value>0.05). CONCLUSION: Among several biomarker, CRP and WBCs are biomarkers that can aid early evaluation of the effects of antibiotic treatment in pyogenic spondylitis. Although PCT did not have statistical significance, it can be used as a biomarker that reflects the effect of antibiotic and severity of infection.

Most cases of spinal subdural hematoma are very rare and result from iatrogenic causes, such as coagulopathy or a spinal puncture. Cases of non-traumatic spinal subdural hematoma accompanied by intracranial hemorrhage are even more rare. There are a few reports of spontaneous spinal subdural hematoma with concomitant intracranial subdural or subarachnoid hemorrhage, but not with intracerebral hemorrhage. Especially in our case, the evaluation and diagnosis were delayed because the spontaneous intracerebral hemorrhage accompanying the unilateral spinal subdural and subarachnoid hemorrhages caused hemiplegia. We report a case of spinal subdural and subarachnoid hemorrhage with concomitant intracerebral hemorrhage, for the first time, with a relevant literature review.
