Background:
Plasmodium vivax is a major pathogen that causes malaria in South Korea.Several genetic polymorphisms in dihydrofolate reductase (pvdhfr), P. vivax multidrug resistance protein 1 (pvmdr1 ), and P. vivax hydroxymethylpterin pyrophosphokinasedihydropteroate synthetase (pvdhps) genes are known to be associated with drug resistance in P. vivax. The objective of this study was to profile the known polymorphisms of P. vivax resistance genes in patients at a secondary hospital in South Korea.
Methods:
A total of 12 patients with confirmed P. vivax infections were enrolled for this study. Sanger sequencing was performed for the pvdhfr, pvmdr1, and pvdhps genes to detect polymorphisms of these drug resistance genes.
Results:
Each specimen had single or double polymorphism in pvdhfr. One specimen had a polymorphism in pvdhps. However, no specimen had any polymorphisms in pvmdr1. There was no strain with multi-polymorphisms exceeding double polymorphisms, which reported the geographic location of treatment failure.
Conclusion
No specimen showed chloroquine-resistance polymorphism in pvmdr1.Treatment with first-line therapy was successful. The prevalence of F57L in pvdhfr was higher than that reported previously. This change must be confirmed by further monitoring and surveillance of the strains with multi-polymorphisms.

Probiotics are used to restore and maintain the healthy intestinal microflora. Although Saccharomyces cerevisiae (SC) is considered as a non-pathogenic yeast, administration of SC as a probiotic is associated with a rare cause of fungemia in immunocompromised patients with central venous catheter insertion. We encountered a case of SC fungemia in a premature infant who presented with respiratory distress syndrome and had undergone central venous catheterization.

BACKGROUND: A variety of agents have been used to treat female pattern hair loss (FPHL), including topical minoxidil, topical 17α-estradiol, oral anti-androgen agents, and mineral supplements. Compared with these single agent regimens, combination therapies could be a better therapeutic option in expectation of superior treatment outcome. OBJECTIVE: This study was designed to determine the efficacy of a combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil in Korean patients with FPHL. METHODS: Therapeutic efficacy was evaluated in 34 women who applied topical 0.025% 17α-estradiol and 3% minoxidil once daily for more than 6 months. Phototrichogram analysis was performed before and after therapy. The efficacy was evaluated with respect to total hair count, hair caliber (as assessed by phototrichogram analysis), and photographic assessment. RESULTS: Total hair count and hair caliber both increased from baseline to 6 months in patients treated with the combination therapy of topical 0.025% 17α-estradiol and 3% minoxidil (p<0.001). Photographic assessment also revealed significant disease improvement, thus supporting the therapeutic efficacy. CONCLUSION: A combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil can be tried as an effective treatment for FPHL.

Vulvar vestibular papillomatosis (VVP) is a benign condition that can be viewed as the female equivalent of male pearly penile papules. Clinically, VVP is quite often misdiagnosed as condyloma acuminatum. As opposed to condyloma, VVP lesions arise from a distinct mucosal base, match the color of the surrounding mucosa, show symmetrical distribution, and are limited to the inner aspect of the labia minora. Although VVP is quite well known in the gynecological field, this disease entity is not commonly recognized in dermatology settings. Furthermore, a literature search for VVP revealed only nine reports in dermatological journals including one report from Korea. Therefore, through our report we wish to create awareness among dermatologists regarding the occurrence of this frequent but often ignored entity. Recognizing and understanding that papillomatosis of the vulvar vestibule is a normal variant will help dermatologists to avoid incorrect diagnosis and repeated unnecessary treatment.

Background:
The aim of this study was to analyze the inhibitory effects of copper, brass (78% copper, 22% tin), and stainless steel surfaces on multidrug-resistant Acinetobacter baumannii (MRAB), extended-spectrum beta-lactamase (ESBL) Escherichia coli , and carbapenem-resistant Klebsiella pneumoniae (CRKP).
Methods:
MRAB, ESBL E. coli, and CRKP were isolated at Uijeongbu St. Mary's Hospital in 2020. A. baumannii ATCC BAA-747, E. coli ATCC 25922, and K. pneumoniae ATCC 700603 were used as reference strains. The initial bacterial cell count of each inoculum was adjusted to 8 log CFU/mL using phosphate buffered saline, Copper, brass, and stainless steel plates were inoculated with 9 mL of MRAB, ESBL E. coli, and CRKP inoculum solutions. The bacterial cell count was measured from the beginning to the 20th day in an incubator maintained at 35°C.
Results:
MRAB, ESBL E. coli, and CRKP isolates were not detected on the copper and brass plates after 4, 5.5, and 6.5 hours, respectively. MRAB, ESBL E. coli, and CRKP isolates were not detected on the stainless steel plate after 15, 20, and 20 days, respectively. The bactericidal effects of copper and brass were much stronger than those of stainless steel.
Conclusion
The use of copper and copper alloys should be considered to prevent crossinfection in hospitals.

Objectives:
Patients undergoing oral surgery exhibit high anxiety, which may elevate their cortisol levels and affect postoperative recovery. Overweight patients are often encountered in the dental clinic due to the increasing prevalence of overweight. We aimed to investigate the relationships between preoperatively assessed body mass index (BMI), serum cortisol and high-sensitivity C-reactive protein (hs-CRP) levels, and visual analog scale (VAS) scores and preoperative anxiety in patients undergoing mandibular third molar (MM3) extraction and to identify predictors of postoperative complications.
Patients and Methods:
We analyzed 43 patients (age, 20-42 years) undergoing MM3 extraction. At the first visit, patients completed the Modified Dental Anxiety Scale (MDAS) and Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaires. Their BMI and VAS scores were also calculated. The participants underwent blood tests 1 hour before MM3 extraction. On the first postoperative day, the participants’ VAS scores and serum hs-CRP levels were reevaluated.
Results:
We found that BMI was significantly correlated with preoperative VAS scores. Further, BMI and preoperative hs-CRP levels were significantly correlated among women and patients undergoing extractions of fully impacted MM3s. No correlations were found between serum cortisol and other variables. The preoperative MDAS and VAS scores were significantly positively correlated, especially among patients undergoing extractions of fully impacted MM3s. Multiple linear regression showed that BMI and the eruption status of the MM3 were significant predictors of postoperative hsCRP levels and VAS scores, respectively.
Conclusion
In MM3 removals, patients with higher BMI showed elevated hs-CRP and higher VAS scores before surgery. Patients with higher anxiety among those undergoing extractions of fully impacted MM3s showed higher preoperative VAS scores. The two main predictors of postoperative complications were BMI and MM3 eruption status.

General anesthesia is associated with a risk for postoperative pulmonary complications. The risk is even higher in patients with chronic respiratory failure, and postoperative mortality rates are high. Proper perioperative anesthetic management is important in such patients. Therefore, it is essential to optimize the patient’s physical status before anesthesia and to determine the optimal anesthesia technique based on the pre-anesthesia evaluation of the patient’s pulmonary function. We successfully performed abdominal surgery under spinal anesthesia in a patient with severe chronic respiratory failure.
