Résumé
Background@#Orbital complications arising from acute rhinosinusitis (ARS) are a major concern for clinicians and serve as important warning indicators of ARS. Prompt recognition and appropriate management are crucial for preventing potential vision-threatening sequelae. Orbital complications of rhinosinusitis are markedly more common in children than in adults. The aim of this study was to investigate the clinical characteristics and treatment outcomes of orbital complications of ARS in adult patients. @*Methods@#This retrospective observational cohort study analyzed the medical records of 176 patients admitted for orbital cellulitis/abscess (ICD code: H050) who underwent orbit or paranasal computed tomography from January 2001 to February 2022 at a tertiary hospital. @*Results@#Eighteen adults with a mean age of 53.2±18.9 years were diagnosed with orbital complications due to ARS: five (27.8%) had preseptal cellulitis, eight (44.4%) had orbital cellulitis, and five (27.8%) had subperiosteal orbital abscess. None of the patients had an orbital abscess or cavernous sinus thrombosis. All patients had unilateral orbital complications (7 right and 11 left) and were managed with intravenous antibiotics for an average of 10.3±6.6 days. Five patients with subperiosteal orbital abscesses underwent intranasal endoscopic drainage at an average of 1.4±1.9 days after admission, while two patients required additional external drainage. Complete recovery was observed in all patients. @*Conclusions@#Conservative antimicrobial therapy can be effective for treating orbital complications from ARS, and not all adult patients require immediate surgical intervention for subperiosteal abscesses. Nonetheless, careful monitoring is essential, and an ophthalmologist must check patients’ visual acuity to prevent irreversible blindness.

Objectives@#. Due to the rarity of olfactory neuroblastoma (ONB), there is ongoing debate about optimal treatment strategies, especially for early-stage or locally advanced cases. Therefore, our study aimed to explore experiences from multiple centers to identify factors that influence the oncological outcomes of ONB. @*Methods@#. We retrospectively analyzed 195 ONB patients treated at nine tertiary hospitals in South Korea between December 1992 and December 2019. Kaplan-Meier survival analysis was used to evaluate oncological outcomes, and a Cox proportional hazards regression model was employed to analyze prognostic factors for survival outcomes. Furthermore, we conducted 1:1 nearest-neighbor matching to investigate differences in clinical outcomes according to the use of neoadjuvant chemotherapy. @*Results@#. In our cohort, the 5-year overall survival (OS) rate was 78.6%, and the 5-year disease-free survival (DFS) rate was 62.4%. The Cox proportional hazards model revealed that the modified Kadish (mKadish) stage and Dulguerov T status were significantly associated with DFS, while the mKadish stage and Hyams grade were identified as prognostic factors for OS. The subgroup analyses indicated a trend toward improved 5-year DFS with dural resection in mKadish A and B cases, even though the result was statistically insignificant. Induction chemotherapy did not provide a survival benefit in this study after matching for the mKadish stage and nodal status. @*Conclusion@#. Clinical staging and pathologic grading are important prognostic factors in ONB. Dural resection in mKadish A and B did not show a significant survival benefit. Similarly, induction chemotherapy also did not show a survival benefit, even after stage matching.

Purpose@#To investigate the effect of detrusor overactivity (DO) on the urethral expression of caveolin (CAV)-1, -2, and -3 of urethra in an animal model of cyclophosphamide (CYP)-induced cystitis rat. @*Methods@#Female Sprague-Dawley rats were divided into the control group (n=20) and the cystitis group (n=20). Cystitis was induced by intraperitoneal injection of CYP (200 mg/kg). An urodynamic study was done 3 days after the CYP injection to measure functional change of the urinary bladder and urethra. Cellular localization and expression of CAV-1, -2, and -3 in the rat urethra were determined by immunohistochemistry (IHC) and Western blot. @*Results@#Urodynamic experiments demonstrated a decreased contraction interval in the cystitis group compared to the control (3.9±1.0 minutes vs. 6.6±1.2 minutes, P<0.05). Conversely, contraction pressure increased significantly in the cystitis group compared to the control (22.4±0.7 mmHg vs. 11.5±0.4 mmHg, P<0.05). The urethral pressure was decreased in the cystitis group compared to the control (4.05 ±2.5 mmHg vs. 5.8 ±2.8 mmHg, P <0.05). The IHC and Western blot data showed that CAV-1, -2, and -3 expression decreased significantly in the cystitis group compared control group (P<0.05). @*Conclusions@#The decreased urethral CAV-1, -2, and -3 in the DO rats suggests that CAVs might be related with the functional change of urethra in association with DO of urinay bladder.
Résumé
Purpose@#The purpose of this study was to examine the relationship of communication competence and communication style with nurse-parent partnership among pediatric nurses. @*Methods@#This study had a descriptive, correlational design. Data were collected from 169 pediatric nurses in B metropolitan city and Y city, from January 2018 to February 2018. A structured questionnaire was administered. Data were analyzed using descriptive statistics, the t-test, one-way analysis of variance, the Scheffé test, the Kruskal-Wallis test, and multiple regression analysis with SPSS version 23.0. @*Results@#Nurse-parent partnership was correlated with communication competence (r=.59, p<.001), an informative communication style (r=.65, p<.001), an affective communication style (r=.68, p<.001), and an authoritative communication style (r=-.30, p<.001). The factors influencing nurse-parent partnership among the study subjects were an affective communication style, an informative communication style, communication competence, and the nurses’ current position. The overall explanatory power of this model was 61.0%, and the most influential factor was an affective communication style. @*Conclusion@#Nurse-parent partnership showed significant correlations with communication competence and affective and informative communication styles. The study may serve as a basic resource for promoting nurse-parent partnership, which increases the effectiveness of treatment for children in pediatric wards and will ultimately help improve the quality of child care.
Résumé
Purpose@#Extravasation of diagnostic and therapeutic materials might occur when the intravascular solution leaks into the surrounding tissues. Injury associated with extravasation depends on various factors. It may range from mild skin reaction to severe necrosis. However, the incidence rate for extravasation is largely unknown because of the limited reporting in Korea. Therefore, this study was conducted to identify the incidence of extravasation and nurses’ attitude and knowledge of extravasation for providing high-quality nursing care. @*Methods@#Three acute care hospitals were surveyed to estimate the occurrence of extravasation. Knowledge and attitude toward extravasation were investigated from 793 nurses working in six hospitals. @*Results@#The incidence rate of extravasation was 0.5%. Extravasation commonly occurred in elderly patients aged 66 or older (59.9%) and internal medicine (48.2%), and it happened 13.73±20.68 days after hospitalization on average.It mostly occurred in the forearm site (52.9%) and was mainly caused by parenteral nutrition (33.6%). The mean scores of nurses’ knowledge and attitude were 14.63±2.86 and 28.91±36.00, respectively. There was a significant negative correlation between the subjects' knowledge and attitude (r=-.11, p=.002). @*Conclusion@#It is necessary to have a reporting system that can accurately monitor the occurrence of extravasation for patient safety management. In addition, it is necessary to develop a protocol that can be applied to clinical practice and a nurse education program.
Résumé
Solitary fibrous tumor (SFT) is a spindle cell neoplasm that occurs commonly in the pleural space. One-third of SFTs arising from an extrathoracic organ are found in the head and neck region, and they arise rarely in the sinonasal tract. Most of these tumors are benign, but malignant tumors are identified in some cases. Here we report a rare sinonasal SFT arising from the frontal recess. A 32-year-old male patient with chief complaint of headache and left facial pain visited the outpatient clinic. He had suffered from paranasal pain and nasal obstruction for several months, and symptoms became more severe in the previous three months. The mass rapidly increased in size and was protruding from the left nostril when he visited the hospital. After computed tomography and magnetic resonance imaging scans, transnasal endoscopic resection of the tumor was performed, and gross total tumor removal was successfully achieved. We believe this case will be helpful for providing information regarding management of such uncommon huge sinonasal tumors originating from the frontal recess.
Résumé
Endoscopic medial maxillectomy (EMM) and its modifications are surgical techniques are used to treat recalcitrant maxillary sinusitis as well as maxillary sinus tumors. In this report, we propose a simple and efficient modification of EMM, called endoscopic trans-turbinal medial maxillectomy (ETTMM), by which the inferior turbinate (IT), nasolacrimal duct, and anatomical integrity of the nasal valve area are preserved. A total of 10 patients (five tumorous and five nontumorous maxillary diseases) underwent ETTMM. Briefly, a turbinate mucosal flap on the superior aspect of the IT was elevated after middle meatal antrostomy. Then a trans-turbinal window was developed to expose the inferior meatus, after which an extended maxillary antrostomy was generated. Finally, the turbinate mucosal flap was repositioned after complete removal of the antral lesions. All lesions were successfully treated using ETTMM. Our modification was easy to perform, and we achieved good endoscopic visualization and accessibility throughout the whole antrum by creating a trans-turbinal window and extended maxillary antrostomy. We could perform postoperative surveillance easily through the wide antrostomy using rigid endoscopes of various angles. ETTMM is a simple and useful modification of EMM that provides clear visualization and great accessibility to most aspects of the maxillary antrum while preserving the nasal functional units, including the IT and nasal valve area.
Résumé
Nasal vestibular stenosis is an uncommon cause of nasal obstruction. There are various causes of the narrowing of vestibule, including previous trauma, surgery, infection, and iatrogenic injury. The disease is characterized by circumferential scar retraction in inlet of nasal cavities which are caused by secondary proliferation of granulation and fibrous tissue. A number of studies were reported on the surgical correction of vestibular stenosis, but no single technique had been widely accepted due to a wide spectrum treatment methods owing to the various causes of disease and deformities of the related anatomy. Here we suggest a new surgical technique for correcting a case of vestibular stenosis caused by trauma.
Résumé
Metastasis to the sinonasal cavity is rare. Late recurrence, such as metastasis developing 10 years or more after nephrectomy, is even more rare. We present a rare case of late metastatic renal cell carcinoma (RCC) in the maxillary sinus after nephrectomy and discuss reported sinonasal metastatic RCC cases. A 64-year-old man presented with left nasal obstruction for the previous one year. He had undergone right nephrectomy to treat RCC 12 years prior. Paranasal sinus computed tomography and magnetic resolution imaging revealed a 4.6-cm-diameter mass exhibiting delayed contrast enhancement that filled the left maxillary sinus and the nasal cavity. Histologically, clear cell RCC was diagnosed. We resected the maxillary sinus tumor to resolve the nasal obstruction for palliative symptom relief. There has been no evidence of recurrence to date, 3 years postoperatively. When a patient with a history of RCC presents with a hypervascular paranasal sinus mass, metastatic RCC should be considered, despite history of nephrectomy. It is important to make an appropriate treatment plan depending on extent of metastases and location of the metastatic tumor.
Résumé
Purpose@#Small bowel obstruction (SBO) is a common disease that requires hospitalization. The most common cause of SBO is postoperative adhesion. Delayed timing of operations in patients who need surgical intervention results in mortality or morbidity. A number of studies on SBO have established criteria for emergency surgery. However, few objective clinical parameters are available for screening patients who need a delayed operation. Therefore, we analyzed factors that affect the clinical course of SBO to select appropriate therapeutic plans for reducing the risk of complications in these patients. @*Methods@#We investigated the clinical characteristics of patients admitted to the surgery department of our hospital between January 1, 2015, and December 31, 2016, who were diagnosed with SBO. Patients were divided into an operative treatment group (n = 12) and a conservative treatment group (n = 96). We compared clinical characteristics between the 2 groups. @*Results@#The operative treatment group underwent more operations before SBO than the conservative treatment group (P = 0.007). Initial leukocyte counts (P = 0.004) and C-reactive protein (CRP) levels (P = 0.028) were elevated in the operative group. Body mass index (BMI) was lower in the operative group (P = 0.013). @*Conclusion@#The number of operations before SBO, leukocyte counts, CRP levels, and BMI were useful parameters for selecting patients who needed an urgent operation for SBO.
Résumé
PURPOSE: The purpose of this study was to identify the self-care agency and quality of life (QOL) among patients with brain tumors after craniotomy. METHODS: A sample of 96 patients was recruited from a university hospital in Seoul. Data were collected through a structured questionnaire from August 2017 to December 2018. Data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson correlations and multiple regression analyses with SPSS 24.0, IBM. RESULTS: The mean scores of the 1st and 2nd stages in the self-care agency increased from 4.75 to 5.15, and in the quality of life rose from 67.94 to 78.60. The score of the second stage was higher than the first in all sub-scales of the self-care agency and the quality. Physical function was the only sub-scale of the self-care agency that affected quality of life in both stages (1st: β=.71, p<.001, 2nd : β=.77, p<.001). CONCLUSION: Based on the result, to improve QOL with brain tumor after craniotomy, it is important to assess physical function of patients and provide appropriate interventions.

Nasal septal perforation is a defect of cartilage, bone, or mucosa of the nasal septum. Nasal septal perforation has several potential causes such as previous septal surgeries, trauma, malignancy, inflammation, or drugs. According to previous studies, successful surgical outcome is affected by the size and location of the perforation. Although many surgical techniques have been reported, there is no standardized nor consistent surgical method for repairing nasal septal perforation. This report suggests a new surgical technique of repairing septal perforation using a posterior perforation-margin-based hinge flap.

Inverted papilloma is a rare sinonasal tumor that mainly occurs in adults during the 5th decade. Three characteristics make this tumor very different from other sinonasal tumors: a relatively strong potential for local destruction, high rate of recurrence, and a risk of carcinomatous evolution. Etiology remains little understood, but an association with human papilloma virus has been reported in up to 40% of cases, raising the suspicions of implication in the pathogenesis of inverted papilloma. Treatment of choice is surgery, by endonasal endoscopic or external approach, depending on extension and tumoral characteristics. We experienced a case of 42-year-old male with inverted papilloma which originated from the ethmoid roof and spread into the frontal sinus. He was treated successfully by unilateral osteoplastic flap surgery without obliteration, and we report on the treatment of this case, along with a review of literature.

BACKGROUND: The olfactory bulb is anatomically exposed and thus can be directly damaged by external stimulation. This can occur as an occupational injury owing to contact with organic solvents or other causes. We present cases of eight patients who sustained occupation-related exposure to potentially toxic substances and later presented with signs and symptoms of anosmia. We examined the occupational and medical characteristics of the patients and evaluated their work-relatedness. CASE PRESENTATION: Case 1: A 50-year-old man performed high-frequency heat treatments for approximately 11 years. He experienced decreased senses for olfaction and taste during the later years culminating in the diagnosis of anosmia after 3 years (high work-relatedness). Case 2: A 54-year-old man whose work involved exposure to various organic solvents, such as spray painting and application of paint and thinners for approximately 4 years, was subsequently diagnosed with anosmia based on rhinorrhea, headache, and loss of olfaction (high work-relatedness). Case 3: A 44-year-old-man who performed spray painting for approximately 17 years developed anosmia (high work-relatedness). Case 4: A 44-year-old man was involved in ship engine cleaning once a month, for approximately 7 h per cleaning session; he was diagnosed with anosmia based on loss of olfaction (low work-relatedness). Case 5: A 41-year-old man worked in ship building block construction for approximately 13 years; anosmia diagnosis was based on loss of olfaction (low work-relatedness). Case 6: A 47-year-old woman performed product inspection and labeling at a plant manufacturing automobile parts; anosmia diagnosis was based on decreased olfaction and taste (low work-relatedness). Case 7: A 50-year-old woman performed epoxy coating in a plant manufacturing automobile parts; anosmia diagnosis was based on diminishing olfaction (low work-relatedness). Case 8: A 57-year-old woman performed cleaning of the area where mobile phone parts were manufactured; anosmia diagnosis was based on diminishing olfaction (low work-relatedness). CONCLUSION: The study results confirmed work-relatedness when the subject was young, and the duration of exposure was long without any other cause of anosmia. Regarding compensation for occupational diseases, work-relatedness can be recognized as a relative concept.

A bronchogenic cyst causing cardiac tamponade is a rare condition. We report an unusual case of a bronchogenic cyst that caused cardiac tamponade. A 49-year-old female patient presented at our emergency room with complaints of palpitations and shortness of breath that had lasted for 5 days preceding the visit. Echocardiography revealed a very large cystic mass compressing the left a trium posteriorly, and a large amount of pericardial effusion caused the diastolic collapse of the ventricles. Atrial fibrillation and aggravated dyspnea were observed, and the patient’s vital signs were unstable after admission. We therefore performed an emergency operation. The bronchogenic cyst was resected by thoracotomy and the patient was discharged 12 days after the operation without any complications over 5 years of follow-up.

Résumé
PURPOSE: In 2008, the Korean Oncology Nursing Society (KONS) published standards for the safe use of chemotherapy in clinical settings, including extravastion management. Although the medical environment has rapidly changed, KONS standards have not been revised since then. In 2017, the KONS planned to revise the practice guidelines on oral chemotherapy METHODS: A clinical expert group developed recommended guidelines, using officially accepted standards based on all relevant publications. The draft was discussed and accepted in a consensus conference. The final recommendations were reviewed and approved by the KONS Boards of Directors. RESULTS: There were 4 chapters and 50 recommendations in the final version of the guidelines. Recommendations include those associated with general practice, patient consent and education, order assessment and administration, and side effects and complication management. CONCLUSION: The revised KONS guidelines on oral chemotherapy will contribute to the improvement of staff and patient safety related to oral chemotherapy. KONS guidelines revisions should be carried out at regular intervals.

BACKGROUND: Paraplegia is a devastating complication following operations on the thoracoabdominal aorta. We investigated whether histidine-tryptophan-ketoglutarate (HTK) solution could reduce the extent of ischemia/reperfusion (IR) spinal cord injuries in a rat model using a direct delivery method. METHODS: Twenty-four Sprague-Dawley male rats were randomly divided into four groups. The sham group (n=6) underwent a sham operation, the IR group (n=6) underwent only an aortic occlusion, the saline infusion group (saline group, n=6) underwent an aortic occlusion and direct infusion of cold saline into the occluded aortic segment, and the HTK infusion group (HTK group, n=6) underwent an aortic occlusion and direct infusion of cold HTK solution into the occluded aortic segment. An IR spinal cord injury was induced by transabdominal clamping of the aorta distally to the left renal artery and proximally to the aortic bifurcation for 60 minutes. A neurological evaluation of locomotor function was performed using the modified Tarlov score after 48 hours of reperfusion. The spinal cord was harvested for histopathological and immunohistochemical examinations. RESULTS: The spinal cord IR model using direct drug delivery in rats was highly reproducible. The Tarlov score was 4.0 in the sham group, 1.17±0.75 in the IR group, 1.33±1.03 in the saline group, and 2.67±0.81 in the HTK group (p=0.04). The histopathological analysis of the HTK group showed reduced neuronal cell death. CONCLUSION: Direct infusion of cold HTK solution into the occluded aortic segment may reduce the extent of spinal cord injuries in an IR model in rats.

Epistaxis is a common disease encountrered in Otorhinolaryngology; however, life-threatening epistaxis during pregnancy is rare, and there are no specific guidelines regarding the management of such patients. We encountered a 38-year-old female patient in the second trimester of her pregnancy, who presented with nosebleeds. No definite focus of bleeding was identified by nasal endoscopy, thus several conservative measures were used to stop nosebleeds including bed rest with head elevation, ice pack application, and nasal packing. Despite such treatments, nosebleeding continued. Endoscopic sphenopalatine artery ligation was conducted under general anesthesia and the results were successful. In obstetric assessment, there was no evidence of fetal distress. The patient delivered a healthy baby at 40 weeks, and there was no recurrence of epistaxis through postoperative 18 months.

BACKGROUND AND OBJECTIVES: Most cases of epistaxis can be controlled by conservative management such electrocautery or nasal packing. However, for some cases of the posterior epistaxis, invasive procedures like endoscopic sphenopalatine artery ligation (SPAL) or arterial embolization are needed. In this study, risk factors present in patients who were hospitalized due to posterior epistaxis and postoperative complications and causes of recurrence after SPAL were analyzed. SUBJECTS AND METHOD: A retrospective chart review of 75 patients who were admitted to Gyeongsang National University Hospital for the treatment of posterior epistaxis between 2009 and 2014 was performed. Demographic factors, seasonal variation, comorbid diseases, and laboratory results were analyzed. Furthermore, 35 patients who have undergone SPAL were surveyed by telephone regarding postoperative complications, and preoperative computerized tomography (CT) images were reviewed to figure out the causes of the recurrence after SPAL. RESULTS: Among 75 patients, 53 (70.7%) were males. Male preponderance (80%) was more definite among those who have undergone SPAL (p=0.04). Age over 40 as well as the winter season and the underlying disease such as hypertension were also critical risk factors for posterior epistaxis. Four out of 35 patients who had undergone SPAL showed recurrence. The bleeding was detected in the branches of sphenopalatine artery in three out of the four patients who experienced recurrent bleeding following SPAL, which were controlled by revision surgery or arterial embolization. CONCLUSION: Posterior epistaxis occurred frequently in men over 40 years of age and in winter. A careful preoperative review of CT images and meticulous dissection during SPAL might be helpful for preventing recurrence after SPAL.
