Purpose: Comparison of the 6-month outcomes of ab externo XEN 45 gel stent implantation with conjunctival resection in Korean glaucoma patients. Methods: From January to May 2021, 43 open-angle glaucoma patients who underwent ab externo XEN stent insertion alone and were followed for more than 6 months were classified into incision (n = 23) and non-incision (n = 20) groups according to the presence or absence of a conjunctival incision and analyzed retrospectively. Qualified or complete success was defined as achieving the personal target intraocular pressure (IOP) with or without medication, respectively. Results: The IOP measured 6 months after surgery decreased significantly in both groups. The number of IOP-lowering drugs required was also reduced. The decrease in IOP after surgery was greater in the non-incision group. Six months after surgery, the qualified success rate was 55% in the non-incision group and 52.2% in the incision group, while the complete success rate was 40% and 8.7%, respectively. During follow-up, 58.1% of the patients underwent bleb needling more than once, and 20.9% underwent additional IOP-lowering surgery, but there was no difference between the two groups. Conclusions XEN stent insertion helped to reduce IOP and the number of IOP-lowering agents after 6 months regardless of a conjunctival incision. However, to maintain the target IOP, bleb manipulation was required in many cases.

Salmonella enterica serotype Choleraesuis causes swine paratyphoid, with clinical findings of enterocolitis and septicemia. However, the clinicopathological features of S. Choleraesuis infections in pigs have not been reported in Korea. We describe the pathological findings of two weaned pigs with S. Choleraesuis infections, presenting with diarrhea, cough, and sudden death. Pathological examination indicated severe necrotic colitis in pig 1 and septicemic lesions in pig 2. Multidrug-resistant S. Choleraesuis was isolated from the pigs’ lungs and intestinal contents. Further research is required for the surveillance of S. Choleraesuis infections in pigs and the virulence estimation in the S. Choleraesuis isolates.

BACKGROUND: Previous randomized controlled trials of revascularization for atherosclerotic renal artery stenosis (ARAS) were not successful. We investigated the effects of percutaneous transluminal angioplasty with stent insertion (PTA/S) on kidney function and blood pressure (BP) control in patients with ARAS. METHODS: From 2000 to 2017, 47 subjects who underwent PTA/S for ARAS were identified. A high-risk group was defined, composed of patients having one or more of the following clinical presentations: pulmonary edema, refractory hypertension, and rapid deterioration of kidney function. Subjects who met the criteria of ‘kidney function improvement’ or ‘hypertension improvement’ after PTA/S were classified as responders. RESULTS: Twenty-one (44.7%) subjects were classified into the high-risk group. Two subjects (8.0%) in the low-risk group (n = 25) and 5 subjects (27.8%) in the high-risk group (n = 18) showed improvement in kidney function after PTA/S (P = 0.110). In patients with rapid decline of kidney function, estimated glomerular filtration rate improved from 28 (interquartile range [IQR], 10–45) mL/min/1.73 m² to 41 (IQR, 16–67) mL/min/1.73 m² at 4 months after PTA/S, although the difference was not significant (P = 0.084). Regarding BP control, 9 (36.0%) and 14 (77.8%) subjects showed improvement after PTA/S in the low- (n = 25) and high-risk (n = 18) groups, respectively (P = 0.007). In patients with refractory hypertension, the systolic BP dropped from 157 (IQR, 150–164) mmHg to 140 (IQR, 131–148) mmHg at 4 months after PTA/S (P = 0.005). Twenty-five subjects were defined as responders and comprised a significant proportion of the high-risk group (P = 0.004). CONCLUSION: PTA/S might improve BP control and kidney function in patients with ARAS presenting with high-risk clinical features. The optimal application of PTA/S should be based on individual assessment of the clinical significance of renal artery stenosis.

There are 82 dental hygiene departments and clinical training institutes across the country with a very wide range of clinical practice content and evaluation methods, making standardization difficult. Therefore, there is a need to establish a standard protocol outlining clinical practice content and evaluation methods for systematic and efficient operation of clinical practice. Thus, this study attempted to propose such a protocol for standardization of dental hygiene clinical practice in dental clinics and hospitals to examine the contents of clinical practice by reviewing relevant literature, and relating it to professional practice within the dental hygienic curriculum to facilitate enhancement of expertise. Clinical practice content was extracted from 74 cases, and was consisted of classifying mandatory and optional clinical practice, training time, and activity methods for each component. To standardize effective clinical practice, it is necessary to organize the components acquired in the course of clinical dentistry training in line with their arrangement on each university's curriculum, in order to learn all components step by step. To do this, it is necessary to present a standardized clinical practice protocol and a organic cooperation between educational institutions and clinical training institutions.

PURPOSE: To characterize the development of glaucoma, age of glaucoma onset, and treatments for patients with a facial port-wine stain (PWS). METHODS: We performed a retrospective analysis of the medical records of 58 patients (116 eyes) with facial PWS between January 2000 and August 2016. We noted patients' age at the initial examination, cup-to-disc ratio, corneal diameter, occurrence of ocular hypertension, development of glaucoma, age of glaucoma onset, and treatments. We compared the clinical features of eyes that developed glaucoma with those that did not develop glaucoma. Among those eyes with glaucoma, we investigated the differences between eyes that underwent surgery and those that did not undergo surgery. RESULTS: Among the 58 patients with a facial PWS (116 eyes), glaucoma was diagnosed in 38 patients (46 eyes; 39.66%). Of these, 26 patients (27 eyes; 58.69%) underwent glaucoma surgery. PWS-associated glaucoma usually developed by the age of 2 years (85.61%). In all patients, glaucoma developed on the same side of the face as the PWS. Of the 58 patients, 19 (32.76%) showed neurological symptoms, including seizures, developmental delays, intellectual disabilities, or hemiplegia, and 32 (55.17%) were diagnosed with Sturge-Weber syndrome. The mean number of glaucoma surgeries was 1.55 ± 0.93. The initial surgery included trabeculectomy (7 eyes), trabeculotomy (5 eyes), combined trabeculotomy/trabeculectomy (13 eyes), and aqueous drainage device insertion (2 eyes). The mean age at the first surgery was 35.14 ± 50.91 months. In 18 of 27 eyes (66.67%), the postoperative intraocular pressure (IOP) was controlled to below 21 mmHg, but 9 eyes (33.33%) showed elevated IOP and required a reoperation. CONCLUSIONS: PWS can be accompanied by ocular hypertension or glaucoma, so patients require regular ophthalmic examinations. When glaucoma occurs, it often does not respond to medication, making it difficult in some cases to control the IOP, so appropriate glaucoma surgery is necessary.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.

PURPOSE: The aims of the current study were to evaluate the effects of superficial cold and heat after spine surgery on pain, satisfaction with pain control and comfort level, and to identify subjective responses and adverse effects. METHODS: A prospective, single-blind, randomized controlled trial was utilized. The intervention group (n=36) received superficial cooling until the wound drain was removed and thereafter followed by superficial heating until discharge, while the control group (n=34) received only superficial cooling until wound drain was removed. Data were collected from August 4 to November 11 2014. RESULTS: There was significant difference in pain according to time within groups (F=71.87, p<.001). However, we found no difference in pain between groups. The intervention group reported higher patient satisfaction with pain control (4 vs 3, z=-2.83, p=.005) and higher comfort level (5 vs 4, z=-4.12, p<.001) than the control group. CONCLUSION: Results indicate that sequential application of superficial cold and heat is a useful method in clinical practice for management of pain after spine surgery.

Diagnoses of pyelonephritis caused by Staphylococcus aureus should be accompanied by investigations of concomitant bladder obstruction and metastatic infections, especially to the spine or heart. Complicated pyelonephritis due to S. aureus requires more than 2 weeks of antibiotics, which is the typically recommended treatment duration for pyelonephritis. We describe a patient who was diagnosed with complicated epidural and paraspinal abscesses after insufficient evaluation and treatment of acute pyelonephritis due to S. aureus. A 62-year-old man with type 2 diabetes was admitted with fever, increased urinary frequency, and left flank pain. He was diagnosed with acute pyelonephritis caused by S. aureus. His fever and flank pain subsided after 3 days of intravenous antibiotics. Evaluation of bladder obstruction and metastatic infection were not performed, as he declined further evaluation. The patient was discharged with oral antibiotics and was requested to attend weekly appointments but was lost to follow-up. One month later, the patient presented at the outpatient clinic with similar symptoms. Computed tomography showed recurrent pyelonephritis and a distended bladder. His flank pain persisted despite administration of an opioid agent. Therefore, magnetic resonance imaging was performed, revealing epidural and paraspinal abscesses. Ultrasound-guided aspiration of the paraspinal muscle layer was performed, and blood and percutaneous aspirated fluid cultures revealed S. aureus growth. The pattern of antimicrobial sensitivity was identical to that at his first admission. Following more than 4 weeks of antibiotics, magnetic resonance imaging showed the abscesses had decreased in size. The patient was discharged without neurologic sequelae and was provided with oral antibiotics.

Picosulfate sodium/Magnesium citrate (PS/MC) is a common bowel cleansing agent for colonoscopy. It is equally effective and better tolerated by patients with regard to taste and volume than polyethylene glycol. However, because of its osmotically active characteristics, PS/MC can cause plasma volume depletion and electrolyte disturbances, such as hyponatremia. Here, we report a case of severe hyponatremia combined with loss of consciousness in a 59-year-old woman following ingestion of PS/MC as bowel preparation for a screening colonoscopy. Upon arrival, serum sodium level was 109 mEq/L and urine osmolality and sodium levels were 393 mOms/Kg and 99 mmol/L, respectively. She was euvolemic and showed normal kidney, thyroid, and adrenal function. Based on these findings, inappropriate anti-diuretic hormone syndrome (SIADH) was diagnosed. She was treated with 3% hypertonic saline and completely recovered without any neurologic sequelae. This case shows that SIADH can be caused by PS/MC (not accompanied by dehydration), even in patients without any underlying renal, heart, or liver diseases.
