PURPOSE: To evaluate quantification results of single breath-hold (SBH) magnetic resonance (MR) cine imaging compared to results of conventional multiple breath-hold (MBH) technique for left ventricular (LV) function in patients with cardiac arrhythmia. MATERIALS AND METHODS: MR images of patients with arrhythmia who underwent MBH and SBH cine imaging at the same time on a 1.5T MR scanner were retrospectively reviewed. Both SBH and MBH cine imaging were performed with balanced steady state free precession. SBH scans were acquired using temporal parallel acquisition technique (TPAT). Fifty patients (65.4 ± 12.3 years, 72% men) were included. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), myocardial mass, and LV regional wall motion were evaluated. RESULTS: EF, myocardial mass, and regional wall motion were not significantly different between SBH and MBH acquisition techniques (all P-values > 0.05). EDV, ESV, and SV were significant difference between the two techniques. These parameters for SBH cine imaging with TPAT tended to lower than those in MBH. EF and myocardial mass of SBH cine imaging with TPAT showed good correlation with values of MBH cine imaging in Passing-Bablok regression charts and Bland-Altman plots. However, SBH imaging required significantly shorter acquisition time than MBH cine imaging (15 ± 7 sec vs. 293 ± 104 sec, P < 0.001). CONCLUSION: SBH cine imaging with TPAT permits shorter acquisition time with assessment results of global and regional LV function comparable to those with MBH cine imaging in patients with arrhythmia.

Purpose: This study investigated the relationship of the partnership between nurses and parents of hospitalized children with the quality of pediatric nursing care as perceived by pediatric nurses. Methods: A cross-sectional descriptive study was conducted among 90 nurses. The data collected were analyzed using the independent t-test and the Pearson correlation coefficient. Results: The level of partnership between nurses and parents showed significant differences by nurses’ age (t=2.22, p=.029) and marital status (t=2.54, p=.013). The quality of pediatric nursing care was found to significantly differ by the nurses’ age (t=2.62, p=.013), marital status (t=4.17, p<.001), whether nurses had children (t=2.53, p=.020), pediatric ward work experience (t=2.43, p=.020), and total work experience (t=2.51, p=.016). The level of partnership between nurses and parents was positively correlated with the quality of pediatric nursing care (r=.48, p<.001). Conclusion To improve the quality of nursing care for hospitalized children and their parents, it is important to consider the specific characteristics of pediatric nurses, whose clinical skills should be improved.

We report complete remission of dural-based leptomeningeal metastasis (LM) in an 80-year-old female patient with non-small cell lung cancer (NSCLC) by osimertinib. She was diagnosed with NSCLC (adenocarcinoma, T4N3M1a) 8 years ago. Mutation analysis of biopsied tissue revealed exon 19 deletion positive, and gefitinib was prescribed. Follow-up chest CT showed a radiological response, and wholebody positron emission tomography 3 years later revealed the disappearance of the previous high-uptake lesions. The medication was continued for maintenance but stopped 4 years later due to intolerable dermatitis. Two years after discontinuing chemotherapy, the patient had a gait disturbance, and brain MRI revealed a right cerebellar mass (diameter [d]=3 cm) with peritumoral edema, compatible with solitary brain metastasis. Retromastoid suboccipital craniotomy and gross total removal of the dura-attached lesion were performed. As the systemic cancer status evaluation revealed no radiological cancer lesion, only tumor bed radiation therapy was given (4,000 cGy/10 fractions) without re-introducing gefitinib. She was followed with a brain MRI at 6-month intervals, and a brain MRI 2 years postoperatively revealed a dural-based extra-axial mass in the left prepontine cistern (d=2.2 cm). Serial cerebrospinal fluid (CSF) cytology was positive for cancer cells. Upon LM diagnosis, the third-generation receptor tyrosine kinase inhibitor osimertinib was given. Two-month follow-up CSF cytology and five consecutive tests over 14 months demonstrated negative conversion. Five-month follow-up brain MRI revealed near complete remission of dural-based LM, and the response was maintained until the 13-month follow-up brain MRI.

BACKGROUND: The oculocardiac reflex (OCR) can be elicited during manipulation of the orbital structures in the strabismus correction surgery. A sinus bradycardia is the most common manifestation of OCR; and cardiac dysrhythmia and asystole may also occur. Various efforts to reduce OCR have been attempted, but without coherent outcome results. METHODS: Sixty one children, undergoing elective strabismus surgery, were randomly allocated into 2 groups: Group K received ketamine 1.0 mg/kg; and Group M received midazolam 0.15 mg/kg for induction of anesthesia. Anesthesia was maintained with 1-1.3 MAC of sevoflurane with 50% N2O in O2. Heart rate and blood pressure were measured 30 seconds before extraocular muscle (EOM) traction and immediately after traction. The OCR was defined as a decrease in heart rate more than 20% of the baseline heart rate, following manipulating EOM. Postoperative nausea and vomiting (PONV) and emergence agitation (EA) were assessed in postanesthetic care unit (PACU). RESULTS: Blood pressure before tightening EOM in Group K was higher than that in Group M (P < 0.05). However Delta HR (2.7 +/- 15% vs. - 0.9 +/- 16%) and incidence of OCR (10.0% vs. 19.4%) after traction an EOM were not different between the two groups. The occurrence of PONV (6.7 vs. 9.7%) and EA (30.0% vs. 22.6%) were similar. CONCLUSIONS: Ketamine does not reduce the incidence of OCR compared with midazolam in pediatric strabismus surgery. In addition, ketamine does not increase the incidence of PONV and EA. In conclusion, it is reliable to use ketamine in pediatric strabismus surgery.

BACKGROUND: Partially paralyzed patients may be placed in the risk of pharyngeal dysfunction. Bupivacaine acts as acetylcholine receptor ion channel blocker and may synergistically interact with rocuronium to augment NM blockade. Thus, this study aims to elucidate whether or not, at a therapeutic concentration, bupivacaine by itself may cause NM blockade and reduce an effective concentration of rocuronium. METHODS: Twenty-two left phrenic nerve-hemidiaphragms (Male SD rats, 150-250 g) were hung in Krebs solution. Three consecutive ST, 0.1 Hz and one TT, 50 Hz for 1.9 s were obtained before drug application and at each new drug concentration. A concentration of bupivacaine in Krebs solution (n = 5) was cumulatively increased by way of 0.01, 0.1, 1, (1, 2, 3, 4, 5, 6, 7) x 10 microM. In a Krebs solution, pre-treated with bupivacaine 0 (n = 5), 0.1 (n = 5), 1.0 (n = 5), 10 (n = 2) microM, and then concentrations of rocuronium were cumulatively increased by way of 1, 3, 5, 7, 9, 12, 14, 16, 18, 20 microM. EC for each experiment were determined by a probit. The EC50's of rocuronium were compared using a Student's t-test with Bonferroni's correction. Differences were considered significant when P < 0.05. RESULTS: The potency of bupivacaine for normalized TF was 11.4 (+/- 1.1) microM. Below 30 microM of bupivacaine, the single twitch potentiation sustained despite the development of tetanic fade and partial inhibition of PTT. Bupivacaine significantly facilitated the NM blockade induced by rocuronium. CONCLUSIONS: Clinicians should be aware that bupivacaine by itself at its therapeutic concentration inhibit NM conduction and enhances rocuronium-induced muscle relaxation.

A variety of anesthetic equipment has been introduced for one-lung ventilation (OLV) during video-assisted thoracoscopic surgeries. A double-lumen endobronchial tube or bronchial blockers are the most common techniques used for achieving OLV. We herein describe a case of general anesthesia requiring both the OLV and two-lung ventilation with a Coopdech bronchial blocker and a single-lumen endotracheal tube. A 43-year-old woman is being scheduled to undertake mediastinal mass removal and tonsillectomy. After performing tonsillectomy by using an endotracheal tube, a Coopdech bronchial blocker is being inserted into her right bronchus for video-assisted thoracoscopic surgery. After her surgery, we have encountered resistance while carefully trying to remove the bronchial blocker. When using fiberoptic bronchoscopy, we have observed that the cuff was being avulsed, which could be removed without difficulty. We thus describe a case in which the balloon cuff was detached and retained in the right bronchus.

The purpose of this study was to compare the changes of retentive force in different stud attachment systems for implant retained overdenture. Two commercially available attachments with different retentive forces were investigated: Kerator (pink, blue, red) and O-ring (orange, red). Two implant fixtures were vertically embedded in base mountings. Five pairs of each attachment were evaluated. A universal testing machine was used to evaluate the retentive force of two attachments during wear simulation. Surface characteristics of each attachment system were evaluated with scanning electron microscopy. Five pairs of each attachment were evaluated. Kerator pink showed the highest initial retention. After 2,500 cycles of wear-simulation, Kerator pink noted the largest decrease in retention. According to results of surface analysis, Worn surfaces were obtained in matrices and patrices. Heavy wears were observed in matrices. After 2 year-wear simulation, most attachments exhibited retention loss. Attachments using different kind of material exhibited dissimilar surface alterations.
