Uterine adenofibroma is an extremely rare benign biphasic neoplasm that is classified into mixed m?llerian tumor. This mass lesion appears to be clinical and histologically benign but it should be differentiated from other malignant neoplasms of uterus. We have experienced a case of uterine adenofibroma in a 53-year-old woman and report this case with a brief review of literature.

BACKGROUND AND OBJECTIVES: Since statins and angiotensin receptor blockers are a frequently prescribed combination in patients with atherosclerotic cardiovascular diseases, we tested the interactive effects of simvastatin and losartan on atherosclerosis in apolipoprotein E (apoE)-/- mice. MATERIALS AND METHODS: Apolipoprotein E-/- mice were fed a high-fat, high-cholesterol (HFHC) diet for 12 weeks, with and without simvastatin (40 mg/kg) and/or losartan (20 mg/kg). The mice were divided into 5 groups and were fed as follows: regular chow (control diet, n=5), HFHC diet (n=6), HFHC diet with losartan (n=6), HFHC diet with simvastatin (n=6), and HFHC diet with both losartan and simvastatin (n=6). RESULTS: Losartan treatment in apoE-/- mice significantly decreased atherosclerotic lesion areas in whole aortic strips stained with Oil Red O. The plaque area measured at the aortic sinus level was reduced significantly by 17% (HFHC; 346830.9+/-52915.8 microm2 vs. HFHC plus losartan; 255965.3+/-74057.7 microm2, p<0.05) in the losartan-treated group. Simvastatin and simvastatin plus losartan treatments reduced macrophage infiltration into lesions by 33% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin; 120556.0+/-39282.8 microm2, p<0.05) and 44% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin and losartan; 103229.0+/-8473.3 microm2, p<0.001, respectively). In mice fed the HFHC diet alone, the smooth muscle cell layer in the aortic media was almost undetectable. In mice co-treated with losartan and simvastatin, the smooth muscle layer was more than 60% preserved (p<0.05). Given alone, losartan showed a slightly stronger effect than simvastatin; however, treatment with losartan plus simvastatin induced a greater inhibitory effect on atherosclerosis than either drug given alone. Serum lipid profiles did not differ significantly among the groups. CONCLUSION: Losartan displayed anti-atherosclerotic effects in apoE-/- mice that were equivalent to or greater than the effects of simvastatin. Combined treatment with these drugs had greater effect than either drug alone.

Korean Journal of Clinical Pharmacy 2023;33(3):186-194
Background:
Interprofessional education (IPE) is important for collaboration between professionals in the team-based practices of the healthcare field.
Objectives:
This study aimed to examine pharmacy students across in Korea on the experience of IPE and the perceptions of the importance of interprofessional collaboration (IPC) and the need of IPE.
Methods:
A cross-sectional survey using a 20 questionnaire to pharmacy students nationwide was conducted from March to May 2019.
Results:
A total of 555 students from 32 pharmacy schools participated. They recognized that the importance of close pharmacist-medical doctor collaboration was an average of 5.38 points (out of 6 points), but the current level of pharmacist-to-medical doctor collaboration was an average of 2.51 points (out of 6 points), and the reasons for the insufficient IPC were the lack of an environment encouraging mutual cooperation (79.5%) and the psychological distance to the other professional (35.3%). They perceived the necessity of IPE between pharmacistmedical doctor was 4.95 points (out of 6 points), with the curriculum including how to cooperate with medical doctors (78.2%), communication skills (51.0%), and understanding of medical doctors’ functions (44.5%), etc. Only 52 respondents (9.4%) had experience in IPE. Respondents who recognized the importance of IPC (≥5 points) showed 4.44-fold higher agreement on the need for IPE than those who did not (≤4 points) (OR 4.44, 95% CI 2.56, 7.68).
Conclusions
Further attention and discussion to add IPE program in the pharmacy school curriculum is necessary in order to cultivate pharmacists with sufficient professional collaboration capabilities.

Objectives:
This study aimed to evaluate the effectiveness of the Jeollabuk-do Suicide Prevention Training Program for professional gatekeeper instructors, using psychological questionnaires.
Methods:
Eighty-three participants were recruited from mental health centers and relevant organizations in Jeollabuk-do. All the participants were randomly assigned to either an experimental group (n=41), where they took part in the suicide prevention training program developed by Jeollabuk-do for professional gatekeeper instructors, or a control group (n=42), receiving no treatment. Four participants from the control group dropped out, and the final participants for each group were 41 and 38. We analyzed the changes in the two groups, before and after the program, using the Korean Suicide Literacy Scale, Counselors’ Professional Scale for Self-injury Behaviors, Attitudes towards the Suicide Scale, and Help-Giving.
Results:
Participants in the experimental group exhibited a significant improvement in their knowledge of suicide prevention and their attitude toward suicide compared to those in the control group.
Conclusion
This study suggests that the Jeollabuk-do Suicide Prevention Training Program for professional gatekeeper instructors may serve as an effective means of improving the participant’s knowledge of suicide prevention and changing the attitude towards suicide, and may fulfill its purpose of preventing suicides.

Purpose:
After periodontal surgery, studies have found that the use of periodontal wound dressing reduces the risk of wound infection and increases healing. The purpose of this study is to evaluate the effect of attachable periodontal wound dressing on the healing and patient satisfaction after periodontal flap surgery.
Materials and Methods:
Twenty-eight patients requiring periodontal surgery underwent periodontal flap surgery on both quadrants of maxilla or mandible. Postoperative pain, bleeding, dietary discomfort and hypersensitivity in relation to attachable periodontal wound dressing was assessed using Visual Analogue Scale (VAS). Additional survey on frequency of burning sensation and overall satisfaction rates were assessed.
Results:
VAS mean values for pain, bleeding, and dietary discomfort depending on the presence and absence of attachable wound dressing were; pain: 2.82, 3.96 (P = 0.002), bleeding: 1.61, 2.54 (P = 0.008), dietary discomfort: 2.82, 4.18 (P < 0.001), respectively. Test groups with attachable wound dressing reported significantly lower rates of discomfort. No significant difference was observed in burning sensation and hypersensitivity related with wound dressing. Satisfaction was higher in 75% of patients who received wound dressing.
Conclusion
According to the results of this study, patients who received attachable periodontal wound dressing reported less postoperative pain, bleeding, and dietary discomfort. There was no statistical significance related to the use of wound dressing with burning sensation and hypersensitivity.

Schaaf-Yang syndrome (SYS) is a rare genomic imprinting disorder caused by truncating mutations in the paternally derived MAGE family member L2 (MAGEL2) allele. It is also responsible for Prader-Willi syndrome, characterized by neonatal hypotonia, developmental delay, intellectual disability, respiratory distress in early infancy, and arthrogryposis. More than 250 individuals with approximately 57 different molecular variants have been reported since 2013, but the phenotype-genotype association in SYS is not yet fully understood. Here, we describe the case of a Korean patient diagnosed with SYS harboring a mutation in the paternal allele of MAGEL2: c.2895G>A, resulting in a protein change of p.Trp965*. The patient’s phenotype included respiratory distress, arthrogryposis, hypotonia, and feeding difficulty in the early neonatal period. Mild renal dysfunction and hearing impairment were observed during infancy.

Purpose:
Extremely preterm infants are prone to brain injury and underdevelopment. Intraventricular hemorrhage (IVH) is the most common cause of brain injury and a significant risk factor for neurodevelopmental delay in preterm infants. Severe IVH is known to have a poor outcome; however, the outcomes of low-grade IVH remain controversial. This study aimed to evaluate neurodevelopmental outcomes and brain segmental volumes of preterm infants with low-grade IVH.
Methods:
This retrospective cohort study included 109 extremely preterm infants who underwent term equivalent age-magnetic resonance imaging and neurodevelopmental evaluation at a corrected age of 18 to 24 months. We compared infants with and without low-grade IVH.
Results:
Among the 109 extremely preterm infants, 25 had low-grade IVH and 84 had no IVH. There were no significant differences in the neurodevelopmental outcomes between the low-grade and no IVH groups. In multivariate analysis, low-grade IVH was associated with a smaller medullary volume (adjusted odds ratio, 0.575; 95% confidence interval, 0.346 to 0.957; P=0.034).
Conclusion
We found no significant differences in the neurodevelopmental outcomes of extremely preterm infants at a corrected age of 18 to 24 months between those with low-grade IVH and those without IVH. Low-grade IVH was associated with a smaller medullary volume.

A two-year-old spayed female pug presented with symmetrical hyperpigmented alopecic lesions on her axillary and inguinal regions. There were no remarkable findings in dermatologic examinations and hormonal assays. Histological examination of biopsied tissues revealed prominent lymphocytic perifolliculitis along with shrunk hair follicles. Immunohistochemistry for CD3, CD79a, CD4, and CD8 showed a positive stain for CD4 antigen around hair bulbs, suggesting CD4 positive T lymphocyte infiltration. This case suggests the possibility that CD4 T lymphocyte-mediated inflammatory reaction could be a main mechanism in canine alopecia areata. Additional studies are warranted to investigate the immunological mechanism in canine species.

Noncirrhotic hyperammonemia as a cause of acute confusion remains diagnostic challenge. Deficiency of ornithine transcarbamylase (OTC) is the urea cycle disorder, inborn errors caused by a defect of the enzymes in the urea cycle, leading to an accumulation of ammonia mainly in newborn. There were very few cases, in which OTC deficiency result in hyperammonemia in adulthood. Herein, we report a young adult woman of hyperammonemic encephalopathy with OTC deficiency, diagnosed by high blood ammonia, glutamine and low plasma levels of citrulline. Next generation sequencing showed the c.386+5G>A mutation of the OTC gene.

Anthriscus sylvestris (L.) Hoffm. is a perennial herb found widely distributed in various regions of Korea, Europe, and New Zealand. The root of A. sylvestris have been extensively used in the treatment for antitussive, antipyretic, cough remedy in Oriental medicine, but the physiologically active function of the leaf of A. sylvestris is as yet unknown. In this study, we investigated the anti-cancer activity and the mechanism of cell death of water extracts of leaf of Anthriscus sylvestris (WELAS), on human FaDu hypopharyngeal squamous carcinoma cells. Our data showed that WELAS treatment inhibited cell viability in a concentration- and time-dependent manner. In addition, the treatment of WELAS markedly induced apoptosis in FaDu cells, as determined by the viability assay, DAPI stain and FACS analysis. WELAS also increased the proteolytic cleavage of procaspase-3, -9 and PARP (poly(ADP-ribose) polymerase). In addition, exposure to WELAS decreased the expression of Bcl-2 (an anti-apoptotic factor), but increased the expression of Bax (a pro-apoptotic factor), suggesting that mitochondria-dependent apoptotic pathways are mediated in WELAS-induced apoptosis. Taken together, these results indicate that water extracts of leaf of A. sylvestris inhibits cell growth and induces apoptosis via the mitochondrial-dependent apoptotic pathway in FaDu human hypopharyngeal squamous carcinoma cells. Therefore, we propose that the water extracts of leaf of A. sylvestris is a novel chemotherapeutic drug, having growth inhibitory properties and induction of apoptosis in human oral cancer cells.
