Purpose: This study investigated the factors associated with transient urinary incontinence (TUI) after holmium laser enucleation of the prostate (HoLEP) as a palliative treatment in patients with severe bladder outlet obstruction (BOO) and advanced prostate cancer (PCA). Materials and Methods: Data of 28 patients with advanced PCA (≥cT3) who underwent palliative HoLEP between October 2018 and March 2021 were included in this retrospective study. After collection of the pre-, intra-, and postoperative (1, 3, and 12 months) data of patients from their medical records, variables of patients with and without TUI at 1 and 3–12 months postoperatively were statistically compared. Multivariate analysis was performed to investigate the factors associated with postoperative TUI. Results: Compared to baseline, the mean total international prostate symptom score, quality of life score, maximum flow rate (Qmax), and postvoid residual (PVR) were significantly improved 1 month postoperatively, and this was maintained until 12 months postoperatively (p<0.001). Of the 28 patients, 14 (50.00%) and 6 (21.43%) presented with TUI at 1 and 3–12 months postoperatively, respectively. Patients with TUI at 1 month follow-up showed a significantly lower preoperative Qmax (p=0.027), larger preoperative PVR (p=0.004), and higher likelihood of bladder neck tumor invasion (p=0.046). Conversely, patients with TUI at 3–12 months postoperatively were significantly older (p=0.033) and had a longer enucleation time (p=0.033). Multivariate analysis demonstrated that the factors affecting TUI were preoperative Qmax (odds ratio [OR]=0.61; 95% confidence interval [CI]=0.39–0.93; p=0.016) and bladder invasion of the tumor (OR=26.72; 95% CI=1.83–390.42; p=0.022) after 1 month; however, none of the variables correlated significantly with TUI at 3–12 months. Conclusions Palliative HoLEP is an effective management option in patients with advanced PCA-related BOO. Lower preoperative Qmax and bladder neck tumor invasion are the factors affecting TUI at 1 month postoperatively.

PURPOSE: Changes in angular deviation before and after general anesthesia and strabismus surgery were examined. METHODS: Twenty patients with intermittent exotropia who were operated on by the same surgeon from January 2014 to October 2017 were included. The basic angle of deviation (preoperative angle of deviation, PreAn) was measured at an outpatient clinic. While lying on a surgical bed under general anesthesia, the bispectral index was referenced, and it was confirmed that there was a sufficient degree of sedation. Photographs were then taken at a height of 40 cm (angle of deviation under general anesthesia, PostAn); while still under general anesthesia, the same procedure was followed immediately after the end of surgery. At 6 months after surgery, the angle of deviation was measured. RESULTS: There were 10 males and 10 females, and the mean age was 7.31 ± 3.59 years. The preoperative angle of deviation was 30.0 ± 13.87 prism diopters (PD) at far fixation; under general anesthesia, 26.46 ± 5.39 PD. There was a significantly positive correlation between the PreAn and angle of deviation under general anesthesia (PostAn - PreAn = −7.67 × PreAn + 19.57; R2 = 0.872; p < 0.00). The angle of deviation changes between pre- and post-anesthesia (PostAn-PreAn) and at the end point of surgery (OP end) and at 6 months after surgery (6mon) also showed a significantly positive correlation (6mon-OP end = 0.317 × [PostAn - PreAn] + 13.098; R2 = 0.334; p = 0.01). CONCLUSIONS: There was a significant positive correlation between the measured angle of deviation pre- and post-anesthesia. We could estimate the degree of change between the angle of deviation immediately after surgery and the stable angle according to the degree of deviation before and after general anesthesia.

PURPOSE: Strabismus affects any age and represents various functional or non-functional eye problems. This population-based study was conducted to determine the prevalence of strabismus and nystagmus in South Korea according to various sociodemographic factors. METHODS: We acquired data from the Korea National Health and Nutrition Examination Survey, a nation-wide cross-sectional survey and examinations of the non-institutionalized civilian population in South Korea (n = 30,538), conducted from July 2008 to December 2011. The prevalence of strabismus and nystagmus were verified, and associated sociodemographic factors was evaluated. RESULTS: The overall prevalence of strabismic disorder in participants over 3 years of age was 1.4 ± 0.1% (95% confidence interval [CI] 1.3–1.6%; 1.5 ± 0.1% in males, 1.3 ± 0.1% in females). The prevalence of exodeviation (15 or more prism diopters), esodeviation (10 or more prism diopters), vertical deviation, and other complicated strabismus and nystagmus was 1.0%, 0.2%, 0.2%, 0.1% and 0.1% respectively. The prevalence was highest in the 6 to 15-year age group (1.9 ± 0.3%), and lowest in the 40 to 49 years age group (0.8 ± 0.1%) (p = 0.005). There were no statistically significant differences for gender, region, residential area, household income, educational level and occupation. CONCLUSIONS: This nation-wide epidemiologic study demonstrated that the prevalence of strabismus and nystagmus according to various sociodemographic factors in South Korea was not statistically significant except for age group. Further investigations are required based on more surveys to better recognize the etiologic or risk factors that may be related to strabismus and nystagmus.

PURPOSE: To investigate the factors associated with the occurrence of and recovery from transient urinary incontinence (TUI) after holmium laser enucleation of the prostate (HoLEP). MATERIALS AND METHODS: From March 2009 to December 2012, 391 consecutive patients treated with HoLEP for benign prostatic hyperplasia were enrolled. Information regarding age, prostate volume, International Prostate Symptom Score, Overactive Bladder Symptom Score, peak urinary flow rate, postvoid residual urine, and operation time was collected. TUI was defined as a patient complaint of urine leakage, regardless of type. Logistic regression was used to investigate the factors associated with the occurrence of TUI, and the Kaplan-Meier test was used to analyze the TUI recovery period. RESULTS: TUI after HoLEP occurred in 65 patients (16.6%), 52 patients of whom (80.0%) showed recovery within three months. Stress and urge urinary incontinence and postvoid dribbling occurred in 16 patients (4.1%), 29 patients (7.4%), and 33 patients (8.4%), respectively. Age (odds ratio [OR]=3.494; 95% confidence interval [CI]=1.565~7.803; p=0.002) and total operation time (OR=3.849; 95% CI=1.613~9.185; p=0.002) were factors that significantly affected the occurrence of TUI. CONCLUSIONS: TUI, defined as any type of urine leakage, occurred after HoLEP in some patients, most of whom recovered within three months. Stress urinary incontinence occurred in only 4% of patients after HoLEP. Age and total operation time were associated with the occurrence of postoperative TUI.

PURPOSE: Polyarteritis nodosa (PAN) is the necrotic vasculitis affecting middle and small-sized arteries throughout the body including ocular tissue. We report an atypical PAN case of unilateral central retinal artery occlusion in which the ocular involvement occurred before systemic symptoms. CASE SUMMARY: A 58-year-old male visited the ophthalmology department due to abruptly decreased visual acuity. Best corrected visual acuity (BCVA) was 0.05 (in the right eye) and 1.0 (in the left eye) basedon the Snellen chart. He complained of acute decreased vision occurring ten days prior and intermittent migraine on the right side with no underlying diseases, such as hypertension or diabetes mellitus. Relative afferent pupillary defect was observed in the right eye. Generalized edema was found around the optic disc and fovea on fundus examination and optical coherence tomography. The patient was diagnosed with central retinal artery occlusion (CRAO) based on a fluorescein angiography. Subsequently, PAN was diagnosed based on clinical features, laboratory test results and imaging studies. The treatment was started with an immunosuppressive agent. One month later, the BCVA was 0.05 based on the Snellen chart. CONCLUSIONS: In PAN patients, decreased vision can occur as a first symptom due to CRAO. If the patient visits the ophthalmology clinic, history taking and laboratory tests for PAN can aid in early diagnosis and treatment, as well as preventing additional complications of PAN.

PURPOSE: To determine the effect of intravitreal bevacizumab injection before panretinal photocoagulation (PRP) in clinically significant macular edema (CSME) patients. METHODS: A total of 91 eyes (70 patients) having severe nonproliferative diabetic retinopathy with CSME requiring PRP were enrolled in the present study; the medical records were retrospectively reviewed and analyzed. The eyes were divided into the regular PRP group (51 eyes) and PRP with preinjection of bevacizumab (1.25 mg) group (combination group, 40 eyes) and compared. Best corrected visual acuity (BCVA) and central macular thickness (CMT) at pretreatment and 1, 3, 6, and 12 months after PRP was evaluated. RESULTS: BCVA (logarithm of the minimum angle of resolution, Snellen visual acuity in parentheses) at pretreatment and 1, 3, 6, and 12 months after PRP was 0.24 (0.575), 0.27 (0.537), 0.28 (0.525), 0.28 (0.525), and 0.30 (0.501) (p = 0.13, 0.15, 0.56 and 0.79) in the regular PRP group and 0.32 (0.479), 0.25 (0.562), 0.26 (0.549), 0.27 (0.537), and 0.36 (0.436) (p = 0.02, 0.04, 0.02 and 0.13) in the combination group, respectively. CMT (microm) at pretreatment and 1, 3, 6, and 12 months after PRP was 257.66, 285.16, 282.21, 289.65, and 309.85 (p = 0.00, 0.00, 0.00 and 0.00) in the regular PRP group and 349.39, 312.17, 331.15. 353.30, and 333.55 (p = 0.04, 0.94, 0.79 and 0.06) in the combination group, respectively. CONCLUSIONS: Pretreatment of anti-vascular endothelial growth factor injection before PRP affected the decrease of macular thickness for 3 months after PRP and improved visual acuity for 6 months after PRP when compared with PRP alone in patients with CSME.

A 29-year-old woman with mild back pain when coughing and suprapubic discomfort after voiding was admitted to Pusan National University Hospital. Two weeks earlier, she had undergone a hysterectomy and right-sided ureteroneocystostomy for uterine atony and right ureteral injury with bladder rupture. Computed tomography showed that a ureteral J stent extended from the right ovarian vein to the right cardiac chamber. The stent was retrieved via both femoral veins with a snare loop and pigtail catheter. Computed tomography showed that the urinary and vascular tracts were normal 5 months after the procedure.

BACKGROUND: Demand of anesthesia for patients with cerebral palsy is more increasing. But there is still lacking in clinical research regarding how BIS and entropy reflect well on sedative and hypnotic state in patients with cerebral palsy. METHODS: Fifteen patients with cerebral palsy (Group CP) and fifteen patients without cerebral palsy (Group NL) scheduled for elective orthopedic surgery were included in the study. Induction of anesthesia was done by having the patient inhale 1 vol% sevoflurane and 100% oxygen using a total fresh gas flow of 8 L/min. Simultaneously BIS, state entropy (SE), response entropy (RE), end-tidal sevoflurane concentration were recorded every 15 seconds till there was no self respiration. When end-tidal sevoflurane concentration had not risen any more for 30 seconds, we increased inhaled sevoflurane concentration in 1 vol% increments. End point of recording was when self respiration was lost or the time sevoflurane concentration reached 8 vol%. RESULTS: No significant differences in RE, SE, BIS at baseline and end point were found between the two groups. No significant difference in the time reach end point was found between the two groups. BIS, SE and RE correlated with end-tidal sevoflurane concentration in the two groups. CONCLUSIONS: The authors found no significant difference in the entropy values between patients with CP and normal patients. Also, the entropy values could be interpreted like BIS in patients with CP. And BIS showed a stronger correlation with end tidal sevoflurane concentrations than entropy.

The present study was performed to investigate the dynamics of Cu,ZnSOD and MnSOD expression following courses of reperfusion after repetitive ischemic preconditioning on the left rectus femoris muscle of Spraque-Dawley rats. Nine or thirty five weeks-old rats were subjected to three, six and ten cycles of ischemic preconditioning that was 5 min ischemia and 5 min reperfusion at the left common iliac artery. Left rectus femoris muscle was isolated 0, 3, 6, 24 and 72 hours of reperfusion after ischemic preconditioning and assayed by immunohistochemical staining with anti-Cu,ZnSOD and anti-MnSOD antibodies. The results were as follows; The immunoreactivities of Cu,ZnSOD and MnSOD were increased in the repectitive three and six cycles of ischemic preconditioning. However, after the repetitive ten cycles of ischemic preconditioning, the Cu,ZnSOD immunoreactivities were decreased in the nine weeks-old rats while MnSOD immunoreactivities were decreased in thirty five weeks-old rats. These findings suggest that severe damayes result from decrease of Cu,ZnSOD in nine weeks-old rats and decrease of MnSOD in thirty five weeks-old rats after ten cycles of ischemic preconditioning.

PURPOSE: A laparoscopic procedure is considered the treatment of choice for an adrenalectomy. We report our experience of a laparoscopic transperitoneal adrenalectomy in a series of 41 patients. MATERIALS AND METHODS: Between February 1999 and September 2004, 41 consecutive patients underwent a laparoscopic transperitoneal adrenalectomy. The indications for a adrenalectomy were primary aldosteronism in 16 patients, Cushing's syndrome in 7, pheochromocytoma in 6, nonfunctional adenoma in 5, adrenal cyst in 3, benign cystic teratoma in 2, myelolipoma in 1 and metastatic renal cell carcinoma in 1. The author analyzed the results of each operation. RESULTS: The affected adrenal gland was successfully removed, with the exception of 3 cases. Conversion to open surgery was necessary in 3 of the pheochromocytoma patients due to massive intraoperative bleeding and severe adhesion to retroperitoneal fat. The mean operative time was 245.3 minutes (125-420). The mean intraoperative blood loss and adrenal mass size were 189.6ml (20-2100) and 3.6cm (1.0-10.4), respectively. The mean post-operative hospital stay was 10.4 days (5-29). The mean times to oral intake and ambulation were 1.4 (1-3) and 1.0 days (1-2) after the operation, respectively. The mean number of days of analgesic administration was 2.1 (0-6). The conversion and major complication rates were 7.3 and 10.5%, respectively. CONCLUSIONS: A laparoscopic adrenalectomy is safe and effective in nearly all adrenal pathologies, with early oral intake, ambulation and a low number of days of pain control.
