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.

Bovine viral diarrhea virus (BVDV) is an economically important worldwide disease in livestock industry. In this study, the occurrence of BVDV in Korean indigenous cattle was performed by RT-PCR using nasal swab. Twelve of 21 cattle were identified as BVDV positive and classified as persistently infected (PI). These animals showed the occurrence of diseases such as diarrhea and pneumonia. BVDV PI outbreaks were found mostly in PI calves. Sequencing and phylogenetic analysis based on the 5'-untranslated region (UTR) showed that our case belonged to BVDV-2a. These results suggested that the nasal swab sampling was available method for the detection of PI animals, underscoring the need for BVDV control strategies in Korean indigenous cattle.

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.

The gross alpha analysis of nasal smear samples for the radiation emergency and the additional follow-up steps were established. Cotton swab sticks using in local hospitals for nasal smear in Korea were used for the verification. The measurement results of standard samples spiked with certified reference source were well agreed within ${\pm}20%$ compared with reference values. The clearance ratio of smear samples conducted with wet smear condition showed higher value. To eliminate the quenching effect of liquid scintillation samples, dry of smear samples should be followed up before counting samples. Based on the measurement results, medical decision levels and internal dose assessment were established for the victims in the beginning of radiation emergency.

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.

Purpose : In February 2007, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections occurred in two newborns in the neonatal unit of Sahmyook Seoul Hospital. We performed this study to investigate the characteristics of MRSA nasal carriage among neonatal unit staffs and the effective infection control measures. Methods : Nasal swab specimens were obtained from the neonatal unit staff for the presence of MRSA. MRSA-colonized staffs were offered decolonization therapy with oral trimethoprim-sulfamethoxazole or 2% mupirocin ointment. Every 2-4months after decolonizaton, repeat nasal swab specimens were obtained. Also, samples from the neonatal unit environment and room air were collected. Results : Successful decolonization was achieved in 92% of the cases in 2 weeks after decolonization therapy, but most of the staffs were recolonized after several months. The nature of antibiotic susceptibility was changed from multi-drugsusceptible to multi-drug-resistant. The most frequently contaminated objects were dressing carts, computer keyboards, bassinets and washbowls. In environmental cultures using the settle microbe count method, the colony counts were decreased significantly at the last study period compared with the first study period in the neonatal room, breastfeeding room, service room, and dressing room (P <0.05). Conclusion : Effective control of sustained MRSA transmission within an institution may require prompt identification, treatment, and monitoring of colonized and/or infected staffs. However, nasal decolonization therapy may induce multi-drugresistant MRSA infection and had no effect on decreasing the MRSA nasal carriage rate in our study. Other factors might be more important, such as improving staff education, increasing hand hygiene practices, and environmental sterilization for controlling MRSA infections.
