OBJECTIVE: We conducted a retrospective data analysis to review the results of robot-assisted arm rehabilitation in post stroke patients during past 2 years and find out positive influences of the outcomes. METHOD: We measured improvements of arm function longitudinally in a group of sixty-four stroke patients, who participated in the robot-assisted arm therapy from January 2012 to December 2013. Treatment session lasted 30 to 40 minutes, 2 to 5 times a week. For at least more than one month, we used the InMotion2.0 (Interactive Motion Technologies, Watertown, MA, USA) and measured outcomes with the Fugl-Meyer assessment-upper extremity (FMA-UE), Korea-modified Barthel index (K-MBI) and InMotion robot arm evaluation index. Also, analysis on the subgroup was carried out. RESULTS: Following the robot-assisted arm rehabilitation, FMA-UE, K-MBI and InMotion robot arm evaluation index were significantly improved compared to baseline. Mean FMA-UE and K-MBI gain were 4.22 +/- 0.76, 7.63 +/- 1.18 in each. However, in the subgroup analysis, the group with less intensity treatment (640 repetition) did not show any significant improvement. CONCLUSION: This is an observational study showing improvements in arm function following robot-assisted arm rehabilitation compared to baseline, which was significant only in the subgroup who received the intervention longer and more intensity.

BACKGROUND: Protein S deficiency is a common cause of thrombophilia. Free protein S has been suggested as one of the best screening tests for this deficiency. We evaluated an immunoturbidimetric free protein S reagent, INNOVANCE Free Protein S Antigen (Free PS Ag; Siemens Healthcare Diagnostics, Germany), using a CS-5100 coagulation analyzer (Sysmex, Japan). METHODS: The performance of INNOVANCE Free PS Ag was evaluated according to the CLSI guidelines. Precision, linearity, and verification of reference intervals were examined. The INNOVANCE Free PS Ag was also compared by the STA-Liatest Free Protein S immunoturbidimetric assay (Diagnostica Stago, France). RESULTS: The repeatability and within-laboratory imprecision of INNOVANCE Free PS Ag were 0.8% CV and 2.0% CV at the normal level, and 1.3% CV and 2.3% CV at the abnormally low level, respectively. This assay showed linearity from 4.0% to 151.9% (correlation coefficient r=1, P < 0.0001). Reference intervals for males and females were verified as acceptable. INNOVANCE Free PS Ag was comparable with STA-Liatest Free Protein S with a very high correlation (r=0.935, P < 0.0001). The results for the INNOVANCE antigen were higher. CONCLUSIONS: The INNOVANCE Free PS Ag on a Sysmex CS-5100 coagulation analyzer has excellent analytical performance and is comparable with the STA-Liatest Free Protein S assay.

BACKGROUND: Little knowledge is available on the characteristic differences between patients with atopic dermatitis (AD) with and without atopic march after childhood. OBJECTIVE: To observe and compare the phenotypes of patients with AD in regards to atopic march tendency at a single point. METHODS: We enrolled patients with AD aged between 10 and 30 years. The patients were divided into the atopic march and non-atopic march groups on the basis of an investigator-designed survey questionnaire, and their serum-specific immunoglobulin E (IgE) levels or results of the skin prick test were compared. RESULTS: In a total of 182 patients enrolled in the study, 93 patients with atopic march and 89 patients with non-atopic march were observed. When their serum-specific IgE levels or results of the skin prick test were compared between the two groups, there was no significant difference, except for a in the atopic march group. Analysis of AD severity, family history of allergic diseases, and total IgE levels between the two groups showed no statistically significant differences. CONCLUSION: Our findings suggest that although no apparent phenotype characteristics could differentiate the presence of atopic march, the history of the patient's allergic diseases should be revalidated, and clinicians should watch out for future developments of atopic march when a patient shows a high-class sensitization rate to dust mite.

Allergen specific immunotherapy (SIT) using house dust mite (HDM) extracts has been performed mainly with patients of asthma and allergic rhinitis. In the meanwhile, there has been a long debate on the efficacy of SIT in atopic dermatitis (AD) with only a few double-blind placebo-controlled trials. However, several randomized controlled trials of SIT in AD revealed significant improvement of clinical symptoms and also, positive result was shown by a following meta-analysis study of these trials. In order to predict and evaluate the treatment outcome, finding a biomarker that can predict treatment responses and treatment end-points is critical but it is very challenging at the same time due to the complexity of causes and mechanisms of AD. Other considerations including standardization of the easiest and safest treatment protocol and optimizing the treatment preparations should be studied as well. This review summarizes the basics of SIT in AD including the brief mechanisms, treatment methods and schedules, and also highlights the clinical efficacy of SIT in AD along with mild, controllable adverse reactions. Immunologic effects and studies of various biomarkers are also introduced and finally, future considerations with upcoming studies on SIT were discussed.

BACKGROUND: Severe pruritus is a challenging condition, and it is more difficult to deal with in older patients due to their limitations in taking oral medication because of underlying diseases, possible interaction with concurrent medications, and poor general condition. OBJECTIVE: We evaluated the efficacy and safety of naltrexone (Revia®), an opioid antagonist, in elderly patients with severe pruritus that was not easily controlled with conventional antipruritics. METHODS: Eighteen patients were enrolled, with a mean age of 73 years. They additionally received 50 mg of naltrexone per day for an average of 2 months. RESULTS: Using the visual analogue scale, 13 (72.2%) of 18 patients showed a "much improved" condition, reporting more than a 50% decrease in pruritus intensity. Sixteen (88.9%) showed symptomatic improvement, and only 2 (11.1%) had persistent pruritus. Five patients reported side effects including insomnia, fatigue, constipation, and anorexia. However, reactions were either limited to the first 2 weeks or well managed. CONCLUSION: Naltrexone could be an effective and safe alternative treatment option to control severe pruritus in older patients.

Guillain-Barre syndrome (GBS) is acute inflammatory demyelinating polyradiculoneuropathy, which is often related to post-infectious etiology. However, GBS has also been reported to be caused by non-infectious factors such as trauma. This report describes a rare case of post-traumatic GBS with dramatic response to immunoglobulin therapy. And here, we also discussed about the importance of differential diagnosis with critical illness polyneuropathy.

Whole-body vibration exercise (WBVe) can provide proper somatosensory stimulation and improve muscle strength in stroke patients. This study investigated the effects of WBVe on gait function and cortical activity in patients with chronic stroke. Thirty stroke patients were randomly assigned to either the WBVe or the control group. The WBVe group received the vibration in a half-squat position for 5 minutes at an intensity of 20 Hz. The control group kept the same posture but did not receive the vibration. Cortical activity was investigated using functional near-infrared spectroscopy (fNIRS). Gait function was assessed by a 10-m walk test (10MWT), a timed up and go (TUG) test, a Fugl-Meyer Assessment, and a Tinetti Performance-Oriented Mobility Assessment (TPOMA). In group analysis of the fNIRS data, oxygenated hemoglobin concentration was significantly increased in the ipsilesional supplementary motor area, bilateral sensorimotor cortex, and contralesional prefrontal cortex in the WBVe group compared to the control group (p < 0.05). Functional assessment demonstrated a significant interaction between time and group for the 10MWT and TUG test, suggesting that the WBVe group demonstrated meaningful improvement after intervention (p < 0.05). These results suggested that WBVe modulated the cerebral cortical activities and resulted in improvement of gait function in chronic stroke patients.

Objective: Dysphagia is a common symptom of stroke and affects 23–50% of such patients. In addition, bulbar involvement, which causes dysphagia, is the primary initial symptom in approximately 25–30% of amyotrophic lateral sclerosis (ALS) patients. The purpose of this study was to compare patterns of swallowing difficulties in stroke and ALS patients. Methods: We retrospectively recruited 84 ALS patients with dysphagia and 294 stroke patients with dysphagia between January 2017 and December 2019. Swallowing processes were reviewed by videofluoroscopic swallowing studies (VFSSs). The presence of oral residues and oral transit times (OTTs) were measured in the oral phase, and the presence of penetration and aspiration and residues in valleculae or pyriform sinuses were evaluated. Statistical analysis was performed using SPSS 25.0 and comparisons using the Chi-square test. Results: ALS patients more frequently had delayed OTTs and oral residues than stroke patients, and stroke patients more frequently experienced aspiration and had delayed thin liquid pharyngeal transit times (PTTs). However, no significant intergroup difference was observed for the presence of penetration, residues in valleculae or pyriform sinuses, or thick liquid PTTs. Conclusion The study shows that ALS patients exhibit slower food processing in the oral cavity and more significant bulbar muscle weakness than stroke patients. On the other hand, stroke patients had greater thin liquid aspiration rates than ALS patients. These findings should be considered when choosing treatments for ALS and stroke.
