Purpose: This study was performed to analyze the predictors that might contribute to urinary retention following semiclosed hemorrhoidectomy under spinal anesthesia. Methods: This retrospective study enrolled 2,176 consecutive patients with symptomatic grade III to IV hemorrhoids who underwent semiclosed hemorrhoidectomy between September 2018 and September 2019. Results: Among the 2,176 patients, 1,878 (86.3%) had no postoperative urinary retention, whereas 298 (13.7%) developed urinary retention after hemorrhoidectomy. The percentage of males was significantly higher in the retention group than in the non-retention group (60.4% vs. 48.1%; P=0.001). The risk of urinary retention was 1.52-fold higher in males than in females (95% confidence interval [CI], 1.13–2.04; P=0.005), 1.62-fold higher in old age (95% CI, 1.14–2.28; P=0.006), and 1.37-fold higher with high body mass index (BMI) (95% CI, 1.04–1.81; P=0.025). Patients with ≥4 resected hemorrhoids had a higher odds ratio (OR) of 1.46 (95% CI, 1.12–1.89; P=0.005) than patients with <4 resected hemorrhoids. Among the supplementary medication, patients who used analgesics had a higher OR of 2.06 (95% CI, 1.57–2.68; P=0.001) than those who did not. Conclusion Male sex, age, high BMI, number of resected hemorrhoids, and supplementary analgesics are independent risk factors for urinary retention after semiclosed hemorrhoidectomy.

Purpose: This study aimed to identify the factors affecting the chemotherapy medication errors made by new nurses and to use the results as basic data for the development of a chemotherapy medication nursing education program for new nurses. Methods: This cross-sectional study was conducted with 189 new nurses working at a general hospital and a tertiary general hospital in Korea. The data collection period was from January 11 to February 7, 2021. The data collected during this study were analyzed using the IBM SPSS statistics version 25.0 program. Data analysis included descriptive statistics, independent t-test, ANOVA, and logistic regression analysis. Results: One factor influencing chemotherapy medication errors was new nurses’ educational needs (odds ratio=.18, p=.005). As educational needs increased, the probability of making errors in medication was reduced by .18. Conclusion It is necessary to develop a chemotherapy medication education program tailored to the educational needs of new nurses by considering the education period, method, and content, with a focus on the content with high demand from new nurses.

Purpose: According to recent studies, magnetic resonance imaging (MRI) assessment of complex fistulas provides a significant benefit compared to fistulography, computed tomography, and ultrasonography. The aim of this study was to describe the accuracy of MRI and the importance of identifying puborectalis muscle involvement on MRI in patients with complex fistula. Methods: All patients who were clinically diagnosed with ‘complex’ or showed multiple fistula tracts underwent fistula MRI. Eligible patients were consecutive patients who underwent fistula MRI between September 2018 and September 2019 at our hospital. Results: A total of 83 patients (74 males, 9 females; 116 tracts) were included in this study. The sensitivity and specificity of MRI in diagnosing fistula tracts were 94.8% and 98.2%, respectively. The sensitivity and specificity in identifying internal opening were 93.9% and 97.3%, respectively. Of the 35 patients with puborectalis muscle involvement in the MRI, 31 images of suprasphincteric-type patients on the Park’s classification were classified. The patients of puborectalis involvement were divided into 2 groups according to the surgical procedure that was performed. There were 12 sphincter-saving procedures and 19 sphincter division procedures performed. Recurrence was seen in 2 patients in the sphincter-saving procedure group, while no case was seen in the sphincter division procedure group. Five complications were found in the sphincter division procedure group, of which 2 reported incontinence. Conclusion Fistula MRI is a highly accurate examination for evaluating complex fistulas, and the puborectalis muscle involvement findings are very important for diagnosis and treatment.

More than half of patients presenting with hoarseness show benign vocal cord changes. However, in rare cases with benign mucosal lesions, it can be diagnosed as a malignant disease after histopathological examination. A 53-year-old man with a 30-pack-year smoking history was admitted for the evaluation of hoarseness, and using a laryngoscope, an enclosed, sac-like cystic lesion was detected on the midpoint of the right true vocal cord. The cystic lesion was deemed to be an intracordal cyst and treated with laryngeal microsurgery. However, pathological findings showed squamous cell carcinoma of the larynx arising in the intracordal cyst, which is exceptionally rare. Therefore, even if a benign lesion is initially suspected, a biopsy must be performed on a patient with smoking history to confirm the diagnosis. In conclusion, we report a case of squamous cell carcinoma of the larynx arising in the intracordal cyst.

PURPOSE: To evaluate the change of intra-abdominal pressure related with intravesical and intrarectal pressure in patients with spinal cord injury according to daily activities and postural changes which make the abdominal pressure elevated. MATERIALS AND METHODS: Ten subjects with lower thoracic and lumbar spinal cord injury were enrolled. Their mean age was 38 years. The urodynamic study was performed and the intravesical and the intrarectal pressures were measured with a double lumen catheter and a intrarectal probe. The intravesical and the intrarectal pressure were obtained during patient's speech, sneeze, cough, valsalva and various postural changes with supine to decuitus, decubitus to supine, supine to sit, and sit to supine according to empty and full bladders, respectively. RESULTS: The order of higher intravesical and intrarectal pressure rise during various maneuvers were valsalva, sneeze, supine to sit and cough, respectively. Higher correlation coefficient between the intravesical and intrarectal pressures were noted during cough, sneeze, valsalva and supine to sit in empty bladder than full one. CONCLUSION: These results demonstrated that the intravesical and intrarectal pressures were influenced by daily activities and postural changes of increasing the intra-abdominal pressure. The intrarectal pressures according to daily activities such as cough, sneeze, valsalva and postural change were significantly related with intravesical pressures.

BACKGROUND: We performed this study to evaluate the appropriate effect-site concentrations of propofol and alfentanil for LMA insertion in ambulatory breast surgery without neuromuscular blockade. METHODS: Seventy-three ASA physical status 1 patients were enrolled. The administration of propofol and alfentanil was titrated versus bispectral index (BIS < 60), systolic blood pressure (SBP > or = 80 mmHg) and heart rate (HR > or = 50/min), respectively. The condition of LMA insertion was assessed as grade 1 (excellent), 2 (acceptable), and 3 (poor) according to gag, cough, movement, and laryngospasm. We recorded SBP, HR and BIS before and after LMA insertion, the effect-site concentrations of propofol and alfentanil at the time of LMA insertion, and the LMA removal time at recovery. RESULTS: The condition of LMA insertion at first attempt was grade 1 in 71.6% of patients, grade 2 in 20.3%, and grade 3 in 8.1%. After the first attempt at LMA insertion, movement occurred in 25.7% and the BIS increased above 60 in 31.5%. The range of the effect-site concentrations of propofol and alfentanil at the first attempt were 2.0 6.0 (3.7 +/- 0.7)microgram/ml and 30.0 150.0 (71.6 +/- 24.4) ng/ml, which reflected a large inter-individual variability. The incidences of hypertension, tachycardia, hypotension, and bradycardia were 6.8%, 1.4%, 11.0% and 5.5%, respectively. The mean LMA removal time was 4.7 min. CONCLUSIONS: LMA was inserted successfully in 91.7% at first attempt and removed promptly at recovery. Movement and increase of BIS above 60 occurred frequently after the first attempt of LMA insertion with the effect-site target-controlled infusion of propofol and alfentanil without neuromuscular blockade.
