Purpose: This study aimed to compare the effects of oral swab and non-swab using cold water gauze on patients' thirst and oral status following nasal surgery under general anesthesia. Methods: A non-equivalent control group was applied. Participants were divided into a control group (n=30) that was treated by cared for with cold water gauze application without oral swab and an experimental group (n=29) that was treated cared for with oral swab using cold water gauze after nasal surgery at the G University Hospital in Korea. Data were collected from May 14, 2020, to April 30, 2021, and analyzed using descriptive statistics, a chi-squared test, independent t-test, Wilcoxon signed-ranks test, and Mann-Whitney test. Results: The results showed no significant differences between the two groups in thirst (U=-0.04, p=.693) and overall oral condition (U=-0.34, p=.813) after the intervention. However, participants' thirst and oral condition were significantly improved in each group after intervention. Conclusions: It was confirmed that both oral care methods reduced thirst and improved oral condition after nasal surgery. These findings indicate the need for intervention for patients' thirst and oral condition after nasal surgery. Furthermore, they show that these oral care protocols can be used as a safe and effective nursing intervention for patients who undergo nasal surgery under general anesthesia.

To control the spread of COVID-19, it is important to identify the infection in its incipient stages so that the infected persons can be dealt with accordingly. The currently used face to face sampling method may increase the risk of infection for medical professionals as it exposes them to the asymptomatic yet infectious patients. This can result in further increases in the load on the medical system and workload of the medical staff. As a solution to this problem, in this paper, we present a robotic system for rapid non-face-to-face automatic nasopharyngeal swab sample collection. The system consists of a custom designed 7-DoF manipulator equipped with a specially developed safety mechanism for restricting the maximum force applied by the tip of the swab. During the swab sampling process, the force applied by the tip of the swab is continuously monitored in real-time by a 3-axis force sensor in order to detect contact with the nasopharynx. The possibility of using this system for automaticnasopharyngeal swab sample collection is proven through experimentation with a phantom model.

A Miniature Schnauzer presented with bilateral mucopurulent nasal discharge and sneezing. Computed tomography of the skull revealed exudates in the nasal cavity and frontal gyrus. Nasal swab cytology showed features of an epithelial-origin tumor. Histopathologic evaluation of the biopsy specimen revealed irregular proliferation of epithelial cells and necrotized tissue. Positive immunohistochemical staining confirmed the epithelial origin of the cells. The dog was diagnosed with nasal carcinoma and was treated with a chemotherapy protocol of carboplatin and piroxicam. This report confirms the effectiveness of combination chemotherapy only without radiotherapy in a dog with nasal carcinoma and provides a guideline for providing alternative treatment.

A 9-year-old male Maltese with foamy nasal discharge, respiratory distress, and sneezing followed by epistaxis was presented to the Veterinary Medical Teaching Hospital of Seoul National University. Radiography showed no significant findings from an open mouth view. Rhinoscopy also did not find any remarkable lesions in the nasal cavity. But when vigorously swabbing the nasal cavity, numerous cells having round nuclei, coarse reticular chromatin, one large nucleolus and distinct cytoplasmic vacuoles, which is typical for canine transmissible venereal tumor cells were collected. We thoroughly searched for any primary transmissible venereal tumor at the other areas of the body other than the nasal cavity, but found none. The patient responded well to vincristine, and the clinical signs resolved with no respiratory distress, sneezing or epistaxis.

The aims of this study were to investigate the nosocomial infection route of methicillin-resistant Staphylococcus aureus (MRSA) and explore preventative methods for this pathogen that involve blocking its dispersion. We cultured MRSA from nasal cavity swabs collected between June and July 2008 that we obtained from eight dental healthcare providers, 32 nurses and the sputum specimens of two patients from our hospital. In addition, we used VITEK 2 equipment to measure drug sensitivity, and we further performed biochemical testing and pulse-field gel electrophoresis (PFGE) to isolate MRSA colonies. The incidence of these bacteria on the nasal swabs was 25.0% from dental clinic healthcare providers, 13.6% from the internal medicine ward nurses and 30.0% from intensive care unit nurses. Moreover, MRSA was detectable in sputum specimens of ward patients. The antimicrobial agents resistance and partial PFGE types of MRSA showed a similar pattern. We suggest from these analyses that nasal cavity infection by MRSA could occur by cross contamination between healthcare providers and patients which underscores the importance of stringent MRSA management practices.

방사선 사고시 피폭환자로부터 채취된 스메어 시료의 전알파 방사능 측정법을 수립하였으며 이를 바탕으로 피폭환자의 후속조치 절차를 확립하였다. 국내방사선사고 대응기관에서 사용중인 스메어용 면봉을 이용하여 계측 절차를 검증하였다. 액체섬광계수기를 이용하여 표준선원을 점적한 시료의 계측 결과 20% 이내에서 인증값과 잘 일치하였으며, 채취 조건은 세정제 등을 이용하는 것이 더 높은 스메어 효율을 보였다. 액체섬광계수법 특성상 소광현상의 영향을 배제하기 위해 건조 등의 최소한의 전처리가 필요 할 것으로 판단되었다. 계측결과를 바탕으로 방사선비상시 피폭환자에 대한 의료적 처치 기준 및 선량평가 절차를 수립하였다.

Two cats were obtained from a cat kennel. Over the previous 7 days, the cats had shown cough, anorexia, depression and nasal discharge. In this study, the consensus PCR was able to detect successfully Mycoplasma species in nasal swab samples of the cats. To identify feline mycoplasma species from the lung tissue of the cats with pneumonia, Mycoplasma species-specific PCR reactions were conducted. As the results, we could identify M. felis by the positive amplified DNAs. On the other hand, we could not detect any positive reactions with the PCR reaction for M. arginini, M. canis, M. edwardii, M. cynos, M. gateae, M. maculosum, M. molared, M. opalescens, M. spumans and Mycoplasma HRC-689. In conclusion, we detected M. felis from the kenneled cats with pneumonia. We suggested that this consensus PCR would be useful and effective for monitoring Mycoplasma species in various kinds of animals including cats. The application of preceding consensus PCR before the species-specific PCRs may be the most recommended strategy for the identification of Mycoplasma spp.

Skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA) can occur especially in community populations such as military training camps. We investigated antimicrobial resistance patterns and molecular epidemiological characteristics of MRSA isolated from nasal swabs in healthy army trainees. From January 2018 to March 2018, one MRSA strain was isolated from nasal swab and hand of healthy army trainees. mecA gene detection, SCCmec and mec complex typing were performed to analyze the antimicrobial resistance patterns and molecular epidemiological characteristics of MRSA isolates. As a result, SCCmec and mec complex type of MRSA isolate from military trainees was not-typeable (n=1). In conclusion, not-typeable subtype of MRSA isolate from military trainees need to be confirmed by continuous follow-up study to determine whether there is a different genotype or a new subtype of genotype present in the Republic of Korea.

목 적: 본 연구는 2명의 정상 신생아에서 다제 감수성을 보이는 MRSA 균주에 의한 피부 고름집이 연속적으로 발생하여 병원 내 신생아실 근무 의료인을 대상으로 MRSA 집락의 특성, 그리고 전파 예방에 대해 알고자 시행하였다. 방 법: 2007년 2월부터 2008년 10월까지 삼육서울병원 신생아실에 근무하는 의료인과 신생아실 물품들을 대상으로 2-4개월 간격으로 의료인 10명의 비강과 손에서 총 7회(비강 45례, 손 44례)에 걸쳐 세균배양 검사 및 항생제 감수성 검사, 신생아실 내 물품을 대상으로 총 8회의 세균배양 검사 그리고 4개월 간격으로 총 6회의 낙하균 검사를 시행하였다. 비강 세균배양 검사에서 MRSA 균주가 동정되었을 경우, 탈집락 요법으로 7일간 trimethoprim-sulfamethoxazole (80 mg/400 mg twice daily) 경구 투여, 혹은 2% mupirocin 연고를 도포하여, 치료 종료 후 2주 후 비강 세균배양 재검사를 시행하여 MRSA가 동정되지 않은 경우를 단기 치료에 성공한 것으로 보고, MRSA가 동정된 경우를 치료에 실패한 것으로 판단하였다. 결 과: MRSA 탈집락요법 2주 후 92%에서 탈집락이 관찰되었으나 대부분에서 2개월에서 16개월 사이에 재 집락이 관찰되었으며 2-4개월 간격으로 시행한 신생아실 근무 의료인의 비강 세균배양 검사 시 마다 16.7%에서 50%의 MRSA 보균이 관찰되었다. 비강 내 MRSA 균주는 초기 다제 감수성을 보이다가 다제 내성 균주 증가 양상이 관찰되었다. 물품 배양검사에서 드레싱 운반차 50%, 컴퓨터 키보드 43.8%, 신생아 침대 25%, 목욕대야 25%, 그리고 전화대야서 18.8%에서 균이 동정되었다. 낙하균 검사에서 연구 초기에 비해 후기에 유의하게 낙하균 감소가 관찰되었다(P <0.05). 결 론: 병원 내 지역 사회 연관 MRSA 유행 시에 선별검사를 통한 보균자의 조기치료가 단기적으로 보았을 때는 항생제의 경구 복용과 비강 도포 모두에서 효과가 좋았으나 장기적으로 보았을 때 유의하게 보균율의 차이가 없었으며 순응도 감소 및 항생제 내성의 증가가 관찰되어 보균자의 조기 치료만으로는 MRSA의 지속적 전파를 차단할 수 없으며, 교육을 통한 손 소독 강화, 주기적인 감시체제를 통한 경각심, 그리고 신생아실 내 손소독제의 사용, 환경 소독 등의 고식적인 방법 들이 더욱 중요하리라 생각된다.
