Diaphragmatic hernias, whether congenital or acquired (traumatic), are rarely observed in the horse. Acquired diaphragmatic hernias typically occur secondary to trauma or an increase in intraabdominal pressure due to falling, heavy exercise, or parturition. Diaphragmatic herniorrhaphy is difficult to perform in adult horses and the horses with symptomatic diaphragmatic hernias usually die. A 10- year old, 340 kg, Jeju horse (crossbred) broodmare with sudden onset of gait disorder and a moderate emaciation was examined. Findings on physical examination included conjunctivitis, dehydration, shallow breathing, dyspnea, weaken heart beat, lack of auscultatable sounds from the gastrointestinal tract, and anorexia. Rectal temperature was $38.4^{\circ}C$ and respiratory rates were moderately increased. There were slight signs of acute colic. The broodmare died one day after non-specific treatment of fluids, nutriment, antibiotics and non-steroidal anti-inflammatory drug. The cause of death was strangulation of the small intestine through a diaphragmatic hernia. The rent was about 2 cm in diameter and located in the central right part of diaphragm. Around 60 cm of small intestine was protruded into thoracic cavity through the rent. The cause of the hernia could not be ascertained. The broodmare had been pastured with many other horses, and the groom had not noticed any aggressive behavior among them. It was, however, speculated that trauma by stallion's attack may have been the cause of the diaphragmatic hernia, because the new horse may be the object of behaviors ranging from mild threats to seriously aggressive kicking, squealing, rearing, and biting.

Extramedullary plasmacytoma (EMP) is a rare disease that occurs in 3% to 5% of patients with plasma cell disorder. It occurs most commonly in the upper respiratory tract and the oral cavity. Very few EMP cases have been reported in the central nervous system (CNS). We report herein an unusual case of EMP in the nasal cavity that recurred in the CNS without systemic involvement. A 67-year-old man visited our hospital due to a month-long bout with exophthalmos. He was diagnosed with EMP in the nasal cavity, paranasal sinus, and orbital cavity. He received radiotherapy to which he had complete responses. After 2 years, he visited our hospital because of a month-long headache. He was diagnosed with EMP recurrence in the CNS via brain magnetic resonance imaging and cerebrospinal fluid analysis. He was treated with whole brain radiotherapy and intrathecal chemotherapy with methotrexate, but he expired due to pneumonia.

The ${\beta}_2$ adrenergic receptor (ADRB2) is a G protein-coupled transmembrane receptor expressed in the human respiratory tract and widely recognized as a pharmacological target for treatments of asthma and chronic obstructive pulmonary disorder (COPD). Although a number of ADRB2 agonists have been developed for use in asthma therapy, indacaterol is the only ultra-long-acting inhaled ${\beta}_2$-agonist (LABA) approved by the FDA for relieving the symptoms in COPD patients. The precise molecular mechanism underlying the pharmacological effect of indacaterol, however, remains unclear. Here, we show that ${\beta}$-arrestin-2 mediates the internalization of ADRB2 following indacaterol treatment. Moreover, we demonstrate that indacaterol significantly inhibits tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$)-induced NF-${\kappa}B$ activity by reducing levels of both phosphorylated-IKK and -$I{\kappa}B{\alpha}$, thereby decreasing NF-${\kappa}B$ nuclear translocation and the expression of MMP-9, an NF-${\kappa}B$ target gene. Subsequently, we show that indacaterol significantly inhibits TNF-${\alpha}$/NF-${\kappa}B$-induced cell invasiveness and migration in a human cancer cell line. In conclusion, we propose that indacaterol may inhibit NF-${\kappa}B$ activity in a ${\beta}$-arrestin2-dependent manner, preventing further lung damage and improving lung function in COPD patients.

Background: Pharmacogenomics is the study of how genetic mutations in patients affect their response to drugs. Pharmacogenomic studies aim to maximize drug effects and minimize adverse drug events. The Food and Drug Administration and the European Medicine Agency published guidelines for pharmacogenetics in 2005 and 2006, respectively; the Korean Ministry of Food and Drug Safety followed suit in 2015. Methods: This study analyzed pharmacogenomic information in the Korean Ministry of Food and Drug Safety's integrated drug information system to evaluate whether domestic pharmaceutical products reflect the current research on pharmacogenomic differences. Results: In June 2020, the Korean pharmacogenomic database contained genomic data on 90 compounds. Of these, 45 compounds were classified as "Antineoplastic and immunomodulating agents." The other 45 non-antineoplastic agents were in the following categories: Anti-infectives, Mental & behavior disorder, Hormone & metabolism related diseases, Cardiovascular system, Skin & subcutaneous tissue disease, Genito-urinary system and sex hormones, Blood and blood forming organs, Nervous system, Alimentary tract and metabolism, Musculo-skeletal system, and Other conditions including the respiratory system. In addition, 30 additives unrelated to the main ingredient were associated with genetic precautions. Conclusion: This study showed that antineoplastic and immunomodulating agents accounted for half the drugs associated with pharmacogenetic information. For antitumor and immunomodulatory drugs, genomic tests were recommended depending on the indication; this was in contrast to genomic testing recommendations for non-antineoplastic medications. Genomic tests were rarely requested or recommended for non-antineoplastic medications because the relationships between genotype and efficacy among those drugs were relatively weak.

A large portion of the Korean population has been exposed to toxic humidifier disinfectants (HDs), and considering that the majority of the victims are infants, the magnitude of the damage is expected to be considerably larger than what has currently been revealed. The current victims are voicing problems caused by various diseases, including but not limited to lung, upper respiratory tract, cardiovascular, kidney, musculoskeletal, eye, and skin diseases, etc. However, there has been difficulty in gaining validation for these health problems and identifying causal relationships due to lack of evidence proving that toxic HD is the specific causes of extrapulmonary diseases such as allergic rhinitis. Furthermore, the victims and bereaved families of the HD case have not received any support for psychological distress such as post-traumatic stress disorder, depression, feelings of injustice, and anger caused by the trauma. In addition, because the underlying mechanisms of the toxic materials within the HDs such as polyhexamethylene guanidine phosphate, poly(oxyalkylene guanidine) hydrochloride, chloromethylisothiazolinone /methylisothiazolinone have yet to be determined, the demand for information regarding the HD issue is growing. The victims of the HD cases require support that goes beyond financial aid for medical costs and living expenses. There is a desperate need for government-led integrated support centers that provide individualized support through health screenings; in other words, we need an integrated facility that provides the appropriate social support to allow the victims to recover their physical and mental health, so as to well prepare them to return to a normal life. The implementation of such a plan requires not only the close cooperation between those departments already directly involved such as the Ministry of Environment and the Ministry of Health and Welfare, but also active support on a national scale from pan-governmental consultative bodies.

프로피온산혈증은 상염색체 열성유전에 의해 발생하는 질환으로, 혈중에 암모니아, 독성 물질 등이 축적되어 경한 증상에서부터 사망에까지 이르는 질환이다. 유병률은 50,000-100,000명당 1명이다. PCCA 또는 PCCB 유전자의 돌연변이로 발생하며, 이것을 규명하는 것이 가장 확실한 진단 방법이다. 두 유형에 따른 임상경과 차이는 뚜렷하게 밝혀져 있지 않다. 발병 시기에 따라 신생아기형과 후기형으로 나눌 수 있다. 증상 발현의 원인은 이화작용을 강화시키는 감염, 스트레스, 변비, 단백질의 과도한 섭취 등이며, 운동실조, 이상행동, 식욕부진, 주기적 구토, 성장장애, 신경발달이상 등의 광범위한 임상 경과를 보인다. 정확한 진단과 조속한 초기 치료가 환자의 생존율 및 신경 발달 장애 여부에 중요한 요소이다. 본 증례는 고암모니아혈증 및 대사산증이 심하지 않았으나 조기에 대사성 질환을 염두에 두고 PCCA와 PCCB 유전자의 돌연변이를 분석하여 프로피온산혈증을 진단하고 적극적인 금식 및 수액 치료와 진단을 통해 신체 발달 및 운동 및 치명적인 신경학적 장애 없이 성장한 고무적인 사례로 이를 보고하는 바이다.

목 적 : 소아 관찰병실(pediatric observation unit: POU)의 운영내역을 분석하여 국내에서도 그 적용이 가능한지를 평가하기 위함이다. 방 법 : 2006년 3월부터 2007년 2월까지 1년간 가톨릭대학교 성모자애병원 소아과 POU에 입원한 환아들을 대상으로 하여 의무기록을 분석하였고 평균재원일수와 병상회전율을 평가하기 위하여 연구기간 1년 전 자료와 비교하였다. 결 과 : 총 1,076명이 POU에 입원하였으며 환아들의 중앙 연령은 2.4세이었고 중앙 재원시간은 14시간 00분이었다. 질환별로는 장염(42.7%)이 가장 많았고 그 외 급성인후염(19.1%), 모세기관지염(7.8%), 폐렴(5.5%), 열성경련(5.2%) 순이었다. 전체 환아 중 7.5%(81/1,076명)는 일반입원으로 전환되어 입원이 연장되었다. 전환율이 낮은 질환들은 변비와 장염, 중이염과 인후염을 포함한 상기도 감염성 질환, 경련성 질환, 후두염이었고 전환율이 높은 질환들은 폐렴, 발열이 조절되지 않은 열성경련, 천식이었다. POU 시행 1년전 자료와 비교할 때, 전체 입원환자의 평균 재원일수는 4.69일에서 3.75일로 감소하였고 병상회전율은 1병상 당 78.8명에서 98.2명으로 증가하였다. 결 론 : POU는 국내에서도 효율적으로 운영될 수 있음을 확인하였다. 향후 POU는 외래와 응급실 진료의 제한점을 보완하며 불필요한 입원기간을 줄일 수 있는 소아과 영역의 새로운 진료 형태로 자리잡을 수 있을 것이라고 기대한다.
