Methods: A total of 79 patients with cervical myelopathy who underwent cervical laminoplasty at our facility between June 2010 and March 2013 were included in this study. Intraoperative control and final waveform were evaluated based on the trapezius muscle MEPs by measuring the latency and amplitude. A neck pain group comprised patients with higher neck pain Visual Analog Scale scores from preoperative value to 1 year postoperatively. The cross-sectional areas of the trapezius muscles and the MEP latencies and amplitudes were compared between patients with and without neck pain. Results: The latency and amplitude of the control waveforms were not significantly different between groups. The neck pain group had a significantly shorter final waveform latency (neck pain: 23.6±2.5, no neck pain: 25.8±4.5; p =0.019) and significantly larger amplitude (neck pain: 2,125±1,077, no neck pain: 1,630±966; p =0.041) than the no neck pain group. Conclusions Postoperative neck pain was associated with the final waveform latency and amplitude of the trapezius muscle MEPs during cervical laminoplasty. Intraoperative electrophysiological trapezius muscle abnormalities could cause postoperative neck pain.

Methods: We included 62 patients who underwent combined LLIF surgery and PPS fixation for degenerative lumbar spondylolisthesis with spinal canal stenosis. We compared the patient demographics and the accuracy of fluoroscopy-guided PPS placement between two groups: patients who remained in the lateral decubitus position for the pedicle screw fixation (single-position surgery [SPS] group) and those who were turned to the prone position (dual-position surgery [DPS] group). Results: There were 40 patients in the DPS group and 22 in the SPS group. Of the 292 PPSs, only 12 were misplaced. In other words, 280/292 screws (95.9%) were placed correctly in the pedicle’s cortical shell (grade 0). PPS insertion did not cause neurological, vascular, or visceral injuries in either group. The breach rates for the DPS and SPS groups were 4.1% (grade 1, 5 screws; grade 2, 3 screws; grade 3, 0 screw) and 4.1% (grade 1, 2 screws; grade 2, 2 screws; grade 3, 0 screw), respectively. Although there were no statistically significant differences, the downside PPS had more screw malpositioning than the upside PPS. Conclusions We found that PPS insertion with the patient in the decubitus position under fluoroscopic guidance might be as safe and reliable a technique as PPS insertion in the prone position, with a misplacement rate similar to that previously published.

Purpose: Despite widespread adoption of open abdominal management (OAM), there is currently no threshold criterion for OAM duration for non-trauma patients. Moreover, there is a positive relationship between morbidity and the duration of OAM, but an uncertain relationship with patients’ age. Therefore, a novel clinical index for the duration of open abdominal management (IDOM) was developed based on the patient’s age and risk of severe complications following OAM to indicate the maximum tolerable number of days of OAM based on the individual’s age. The utility of this new index was evaluated. Methods: This retrospective study included 65 non-trauma patients managed with an open abdomen (OA) from August 2015 to August 2018. The IDOM was developed based on the patient’s age. The result indicated the maximum number of OA days. Patients’ demographic and operative variables were examined and patient data was assigned to one of two groups according to whether the actual number of OA days was above or below the calculated IDOM. Prevalence of complications between these groups was compared. Measures of validity were employed to assess the utility of the IDOM for patient complications. Results: Sixty-five patients were included. The above-the calculated IDOM group exhibited a significantly longer OA and higher rates of wound complications and postoperative respiratory complications compared with the below the calculated IDOM group. The IDOM predicted the incidence of OA-related complications with a sensitivity of 72.4%, and a specificity of 80.6%. Conclusion The IDOM is a potentially useful tool for appropriate duration at the outset of OA.

Adenocarcinoma currently accounts for 10–25% of all uterine cervical carcinomas and has a variety of histopathological subtypes. Among them, mucinous carcinoma gastric type is not associated with high-risk human papillomavirus (HPV) infection and a poor prognosis, while villoglandular carcinoma has an association with high-risk HPV infection and a good prognosis. They show relatively characteristic imaging findings which can be suggested by magnetic resonance imaging (MRI), though the former is sometimes difficult to be distinguished from lobular endocervical glandular hyperplasia. Various kinds of other tumors including squamous cell carcinoma should be also differentiated on MRI, while it is currently difficult to distinguish them on MRI, and HPV screening and pathological confirmation are usually necessary for definite diagnosis and further patient management.

BACKGROUND: The canonical Wnt/β-catenin signaling pathway is a fundamental regulatory system involved in various biological events. ICG-001 selectively blocks the interaction of β-catenin with its transcriptional co-activator cyclic AMP response element-binding protein (CBP). Recent studies have provided convincing evidence of the inhibitory effects of ICG-001 on Wnt-driven disease models, such as organ fibrosis, cancer, acute lymphoblastic leukemia, and asthma. However, the effects of ICG-001 in atopic dermatitis (AD) have not been investigated. OBJECTIVE: To investigate whether β-catenin/CBP-dependent signaling was contributed in the pathogenesis of AD and ICG-001 could be a therapeutic agent for AD. METHODS: We examined the effects of ICG-001 in an AD-like murine model generated by repeated topical application of the hapten, oxazolone (Ox). ICG-001 or vehicle alone was injected intraperitoneally every day during the development of AD-like dermatitis arising from once-daily Ox treatment. RESULTS: Ox-induced AD-like dermatitis characterized by increases in transepidermal water loss, epidermal thickness, dermal thickness accompanied by increased myofibroblast and mast cell counts, and serum levels of thymic stromal lymphopoietin and thymus and activation-regulated chemokine, and decreases in stratum corneum hydration, were virtually normalized by the treatment with ICG-001. Elevated serum levels of periostin tended to be downregulated, without statistical significance. CONCLUSION: These results suggest that β-catenin/CBP-dependent signaling might be involved in the pathogenesis of AD and could be a therapeutic target.

BACKGROUND/AIMS: This study aimed to identify the predictive factors for inaccurate endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) diagnosis of swollen lymph nodes without rapid on-site cytopathological evaluation. METHODS: Eighty-three consecutive patients who underwent EUS-FNA for abdominal or mediastinal lymph nodes from January 2008 to June 2017 were included from a prospectively maintained EUS-FNA database and retrospectively reviewed. The sensitivity, specificity, and accuracy of EUS-FNA for the detection of neoplastic diseases were calculated. Candidate factors for inaccurate diagnosis (lymph node size and location, needle type, puncture route, number of passes, and causative disease) were evaluated by comparison between accurately diagnosed cases and others. RESULTS: The final diagnosis of the punctured lymph node was classified as neoplastic (65 cases: a metastatic lymph node, malignant lymphoma, or Crow-Fukase syndrome) or non-neoplastic (18 cases: a reactive node or amyloidosis). The sensitivity, specificity, and accuracy were 83%, 94%, and 86%, respectively. On multivariate analyses, small size of the lymph node was the sole predictive factor for inaccurate EUS-FNA diagnosis with a significant difference (odds ratios, 19.8; 95% confidence intervals, 3.15–124; p=0.0015). CONCLUSIONS: The lymph node size of <16 mm was the only independent factor associated with inaccurate EUS-FNA diagnosis of swollen lymph nodes.
