Comparison between GlideRite® rigid stylet and Parker Flex-It™ stylet to facilitate GlideScope intubation in simulated difficult intubation: a randomized controlled study

The GlideScope® videolaryngoscope (GVL) is widely used in patients with difficult airways and provides a good glottic view. However, the acute angle of the blade can make insertion and advancement of an endotracheal tube (ETT) more difficult than direct laryngoscopy, and the use of a stylet is recommended. This randomized controlled trial compared Parker Flex-It™ stylet (PFS) with GlideRite® rigid stylet (GRS) to facilitate intubation with the GVL in simulated difficult intubations. Methods: Fifty-four patients were randomly allocated to undergo GVL intubation using either GRS (GRS group) or PFS (PFS group). The total intubation time (TIT), 100-mm visual analog scale (VAS) for ease of intubation, success rate at the first attempt, use of laryngeal manipulation, tube advancement rate by assistant, and complications were recorded. Results: There was no significant difference between the GRS and PFS groups regarding TIT (50.3 ± 12.0 s in the GRS group and 57.8 ± 18.8 s in the PFS group, P = 0.108). However, intubation was more difficult in the PFS group than in the GRS group according to VAS score (P = 0.011). Cases in which the ETT was advanced from the stylet by an assistant, were more frequent in the GRS group than in the PFS group (P = 0.002). The overall incidence of possible complications was not significantly different. Conclusions: In patients with a simulated difficult airway, there was no difference in TIT using either the PFS or GRS. However, endotracheal intubation with PFS is more difficult to perform than GRS.

Dry sauna therapy is beneficial for patients with low back pain

BACKGROUND: Dry sauna has been very popular as an alternative therapy for promoting health among people who want to improve their health condition without relying on pharmaceuticals. The aim of this study was to investigate whether dry sauna therapy improved quality of life and reduced pain in participants with low back pain.METHODS: Study participants comprised a total of 37 consecutive patients who were over 20 years of age with low back pain. Dry sauna therapy was performed twice per day for 5 consecutive days over the course of 1 week, thus comprising a total of 10 sessions each of 15 min of exposure to a 90℃ dry sauna.RESULTS: The verbal numerical rating scale (VNRS) and Oswestry disability index (ODI) scores were significantly reduced after dry sauna therapy (P < 0.001 for both). VNRS pain scores had a median (range) of 5 (2–8) before dry sauna therapy and 3 (0–8) after dry sauna therapy. ODI scores had a median (range) of 12 (2–24) before dry sauna therapy and 8 (1–17) after dry sauna therapy. The proportion of participants who reported successful treatment (excellent + good) was 70%. No adverse effects were observed related to dry sauna therapy.CONCLUSIONS: Our results suggest that dry sauna therapy may be useful to improve quality of life and reduce pain in patients with low back pain. Therefore, pain physicians can recommend dry sauna therapy as an alternative and complimentary therapy for patients with low back pain.

Scabies mimicking graft versus host disease in a hematopoietic cell transplant recipient / 소아과

Scabies is a highly contagious skin infestation caused by the mite, Sarcoptes scabiei var. hominis. Complex responses to scabies mites in the innate, humoral, and cellular immune systems can cause skin inflammation and pruritus. Diagnosis can be challenging because scabies resembles other common skin conditions. We report the first Korean case of scabies in a hematopoietic cell transplant (HCT) recipient, initially suspected of skin graft versus host disease (GVHD). A T-cell acute lymphocytic leukemia patient underwent a sibling-matched allogeneic HCT and developed pruritus after cell engraftment. Treatment for GVHD did not improve the symptoms. He was diagnosed with scabies 30 days after the onset of symptoms.

Clinical Significance of Serum C1q-Circulating Immune Complexes in Patients with Lupus Nephritis / 대한류마티스학회지

OBJECTIVE: The purpose of this study was to evaluate whether serum C1q-circulating immune complexes (C1q-CIC) serve as a predictive marker for renal flares in patients with lupus nephritis. METHODS: Twenty-five patients with lupus nephritis and 24 healthy controls were enrolled. Patients with lupus nephritis had their serum C1q-CIC titers and other serologic parameters such as serum C3, C4, anti-dsDNA antibody, and erythrocyte sedimentation rate measured simultaneously. The systemic lupus erythematosus disease activity index (SLEDAI) was also checked. RESULTS: Serum C1q-CIC titers were higher in patients with lupus nephritis than in healthy controls (109.33+/-53.79 microg/mL vs. 75.28+/-22.91 microg/mL, p=0.008). A statistically significant association was found between serum C1q-CIC titers and C3 (p=0.011), C4 (p=0.027), and anti-dsDNA antibody (p=0.014). SLEDAI was also correlated with serum C1q-CIC titers (p=0.022). CONCLUSION: Serum C1q-CIC appears to be related to renal disease activity in patients with lupus nephritis. These results suggest that serum C1q-CIC is a predictive marker for renal flares in patients with lupus nephritis.

Determining Clinical Risk Factors for Radiographical Severity in Patients with Ankylosing Spondylitis in Daegu and Kyungpook Territories / 대한류마티스학회지

OBJECTIVE: This study was designed to identify prognostic determinants of radiographical severity in patients with ankylosing spondylitis (AS) living in Daegu and Kyungpook territories. METHODS: One hundred-nineteen patients with AS were consecutively enrolled from four regional general hospitals. Clinical data including smoking habits, alcohol intake, disease duration, HLA-B27 positivity, involvement of peripheral joints, occupational activity, and regular exercise were investigated. Radiographical severity was assessed by the Modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). Statistical analyses were performed using the independent Student's t-test, Pearson's correlation coefficient analysis, and multivariate regression analysis. RESULTS: Radiographical severity, as evaluated with the mSASSS, was associated with age of disease onset (p=0.011) and disease duration (p<0.001). Additionally, mSASSS was significantly higher in males than females (p=0.039) and in patients without involvement of ankle arthritis than those with involvement of ankle arthritis (p=0.026). Patients with hip arthritis had significantly higher mSASSS scores than those without hip arthritis. A multivariate regression analysis showed that older age of disease onset, male gender, and disease duration were independent predictors of AS radiographical severity (p<0.001, p=0.013, and p<0.001, respectively). Hip arthritis was an independent predictor of C-spine radiographical severity in AS (p=0.031). CONCLUSION: Radiographical severity of the prognosis was determined by age of disease onset, gender, and disease duration in patients with AS living in Daegu and Kyungpook territories.
