Objective: Epinephrine is a first-line drug for anaphylaxis, but a poor prognosis can occur if not administered properly. This study compared the clinical features of patients with anaphylaxis in the emergency department (ED) according to epinephrine administration. Methods: This was a retrospective cross-sectional study using ED-based data retrieved from a tertiary university hospital. Patients diagnosed with anaphylaxis between 2018 and 2020 were enrolled in this study. The patients with anaphylaxis were classified according to epinephrine administration, and the clinical features were compared. The adjusted odds ratios (AORs) with a 95% confidence interval (CI) were calculated for the main factors associated with epinephrine use. Results: Among 205 eligible patients with anaphylaxis, 157 (76.6%) were treated with epinephrine. The main contributing factors influencing epinephrine use were patients with cardiovascular symptoms (AOR=2.97; 95% CI, 1.26-7.01) and patients transferred from other hospitals (AOR=0.37; 95% CI, 0.16-0.85). Conclusion The major factors influencing epinephrine use in the ED when patients with anaphylaxis presented with cardiovascular symptoms were identified. It is essential to prevent potentially fatal consequences in patients with anaphylaxis through appropriate epinephrine administration.

The aim of this study was to evaluate and compare the reorganization of corticospinal pathways innervating upper extremity muscles in patients with spastic hemiplegic cerebral palsy (CP). Thirty-2 patients (17 male, 15 female) with spastic hemiplegic CP were enrolled. The average age (mean ± standard deviation) was 7.5 ± 4.6 (range: 2–17) years. Transcranial magnetic stimulation (TMS) was applied to the unaffected and affected motor cortices in turn, and bilateral electromyographic recordings were made from the first dorsal interossei (FDI), the biceps brachii (BB), and the deltoid muscles during rest. The onset latency, central motor conduction time, and peak-to-peak amplitude of motor evoked potentials (MEPs) were measured for each muscle bilaterally. Whilst TMS of both affected and unaffected hemispheres elicited contralateral MEPs in all muscles, the number of MEPs evoked from the affected hemisphere was less than from the unaffected hemisphere for FDI and BB. TMS responses to stimulation of the affected side showed prolonged latency and reduced amplitude. The amplitudes of MEPs increased with age whereas the latencies were relatively constant. These results suggest that the corticospinal pathways to the proximal and distal muscles of the upper extremity undergo sequential maturation and reorganization patterns.

Recently, new treatments for human heart disease such as ischemia, infarction, cardiomyopathy, coronary heart disease have been developed. transplantation various kinds of cells from skeletal muscle, endothelium, mesenchyme, hemopoietic tissue to injured area after infarction were challenged. It's so called 'Cell Transplantation'. This therapeutic strategy already adopted and got a good result in clinical trial. But several limitations are still remained, including ethics, donor cell numbers, side effects, therapeutic efficiency. In this research, we investigated the formation of intercellular junction and synchronous contraction between cardiomyocyte and H9c2 cell line in co-culture to establish experimental model in vitro for cell transplantation. For this purpose, two kinds of cells, primary cultured cardiomyocyte and H9c2 (cardiomyoblast cell line) were used. Cultured cardiomyocytes had repetitive contraction-relaxation pattern along longitudinal axis both in single and coculture. But their contractions were slower, less regular, less strong in co-culture than in cardiomyocyte culture only. H9c2 cells did not contracted actively themselves, but moved toward cardiomyocyte passively coincided with contraction. In contact region between two kinds of cells, there was no signal after immunocytochemical staining labeled with connexin43 (gap junction), desmoplakin (desmosome), N-cadherin (adherent junction) even though they had membrane contact. Moreover, F-actin and striation were less developed. These results suggested that co-culture system interfere with remodelling of contractile apparatus, intercellular junction formation as well as contraction-relaxation. Furthermore cardiomyocyte could not induce H9c2 cells differentiation into cardiomyocyte. Therefore, much more research would be essential for clinical application of cell transplantation and this study would be the basic source for further study of new therapy of myocardial disease and building up in vitro model.

BACKGROUND: Several studies have been conducted on the role of the p63 gene family in non-small cell lung carcinoma (NSCLC). Nevertheless, the role of these genes in the development and progression of NSCLC remains controversial. This study was designed to examine the expression and clinicopathologic significance of the p63 family in NSCLC. METHODS: Immunohistochemical staining was performed on 92 cases of NSCLC (47 squamous cell carcinomas [SqCCs] and 45 adenocarcinomas [ACs]) using tissue microarray blocks. The results were analyzed and correlated with clinicopathologic data. RESULTS: The expression of delta Np63 (Delta Np63) was elevated in SqCC (39/47), but not in AC (2/45; p<0.01). Both p63 and Delta Np63 had high expression in 39 SqCCs; p63 and Delta Np63 also had a similar geomorphologic distribution in most positive tumors. The expression of Delta Np63 was correlated with histologic type, gender, pT stage, p53 expression, and p63 expression. pT and pN stages were independent factors in survival (p<0.05, respectively). CONCLUSIONS: The major p63 isoform in NSCLC, Delta Np63, had a strong correlation with p53 and p63, and was exclusively expressed in SqCC. However, our findings suggest that Delta Np63 was not an independent prognostic factor for NSCLC.

Objective: To determine the effects of an integrated training device for strength and balance on extremity muscle strength, postural balance, and cognition in older adults using a combination with various rehabilitation training games, in which balance, strength, and cognitive training were configured in a single device. Methods: This prospective study included 20 healthy participants aged 65–85 years. Participants trained for 30 minutes daily, 3 days weekly, for 6 weeks with an integrated training device for strength and balance (SBT-120; Man&Tel Inc., Gumi, Korea). Main outcomes were measured using the Korean Mini-Mental State Examination (K-MMSE), Korean version of the Montreal Cognitive Assessment (K-MoCA), Timed Up and Go Test (TUG), Functional Reach Test (FRT), Berg Balance Scale (BBS), and Manual Muscle Test. Measurements were taken at three time points: T0 (pretreatment), T1 (immediately after treatment), and T2 (4 weeks after treatment). Results: All 20 patients completed the training, and TUG, FRT, and BBS scores significantly improved at T1 and T2 compared to T0. Mean TUG scores decreased by 0.99±2.00 at T1 and 1.05±1.55 at T2 compared to T0. Mean FRT scores increased by 6.13±4.26 at T1 and 6.75±4.79 at T2 compared to T0. BBS scores increased by 0.60±0.94 at T1 and 0.45±1.15 at T2 compared to T0. Moreover, muscle strength and cognition (K-MMSE and K-MoCA scores) increased after training. Conclusion Our findings suggest that an integrated training device for strength and balance can be a safe and useful tool for older adults.

We measured the difference of sitting pressure between the affected and unaffected sides (DSPAU) using sitting pressure measured with a force platform to identify sitting imbalance. The aim of this study is to investigate the relations between sitting balance and functional status or parameters according to characteristics stroke patients. We examine changes in DSPAU and functional assessment before and after a 3 week of rehabilitation in hemiplegic stroke patients (n = 73). These pre- and post-treatment data according to stroke characteristics, and correlations between the DSPAU and functional scales were analyzed. The DSPAU was greater in the non-ambulatory group compared to the ambulatory group, in patients who scored lower in the Medical Research Council (MRC) scores, and in patients whose the MRC scores for the lower limbs were lower than of the upper limbs. We observed that a decrease in the DSPAU was associated with an improvement in functional assessment parameters following rehabilitation. Further, changes in DSPAU were significantly correlated to the Modified Barthel Index. We observed that a decrease in DSPAU was associated with an improvement in functional parameters following rehabilitation. In conclusion, repeated measurements of sitting balance using DSPAU may be helpful to predict motor and functional recovery in stroke patient with hemiplegia.

Bertolotti's syndrome (BS) is a disease that should be differentiated from low back pain (LBP) in young patients. BS shows an anatomical abnormality in which elongated transverse processes of the last lumbar vertebra articulate or fuse with varying degrees to the sacrum or ilium according to radiologic findings, which is associated with the clinical feature of LBP or radiating pain. In this case report, we describe various clinical features such as a waddling gait with severe foot and triceps surae muscle pain, in addition to the typical symptom of BS such as LBP. We report the various clinical symptoms and treatment progress in this case and review the literature.
