  • 목 적: 심근의 단독 비경화증은 성인을 대상으로 산발적인 보고가 있었으나 소아에서는 정확한 혈역학적인 양상, 장기적인 예후, 유전 양상 등에 대해서는 많이 알려지지 않은 상태이다. 저자들은 심근의 단독 비경화증을 보이는 환자군의 임상 양상, 혈역학적인 성상과 경과, 형태학적 특성 및 유전양상 등을 평가하고자 본 조사를 시행하였다. 방 법 : 충남대학교병원 소아과에서 1997년부터 2001년까지, 심초음파 검사를 통하여 심근의 단독 비경화증으로 진단받은 10명(남아 5명, 여아 5명)을 대상으로 임상 양상, 혈역학적인 성상과 경과, 형태학적 특성 및 유전양상 등을 조사하였다. 결 과: 환자들의 진단시의 평균 연령은 $45{\pm}53$개월(1일-14세)이었으며, 평균 추적 관찰 기간은 $33{\pm}19$개월이었다. 남녀비는 동일하였다. 심초음파 검사시 발현 증상은 부정맥 3명, 태아 초음파 검사상 서맥 2명, 심잡음 4명이었다. 다른 심기형이 동반된 환자는 6명으로, 3명은 심실중격결손 또는 심방중격결손이 있었고, 2명은 승모판 탈출증이 동반된 동맥관 개존증, 1명은 승모판 열극이 있었다. 2명에서 심전도상, II, III, aVF 유도에서 T파의 하강이 관찰되었고, WPW 증후군의 환자는 1명으로 발견 당시 발작성 상실성 빈맥이 동반되었다. 2명에서 가족성 동기능 장애가 발견되었으며, 제 3도 방실 차단이 1명의 환자에서 있었다. 심초음파 검사 상 지주 간 고랑의 정도는 승모판 수준에서 심첨부로 갈수록 심하였다. 가족적 발생을 보인 2명에서 가족성 동기능 장애를 동반하였다. 추적관찰 중 대부분의 환자는 무증상이나, 2명에서 좌심실수축기능 저하가 있었고, 이 중 1명은 심한 동기능 장애로 영구 심박 조율기 삽입 시술이 필요한 상태이다. 결 론 : 소아에서 심근의 단독 비경화증은 아주 드문 질환은 아니며, 성인과 마찬가지로 심근기능 장애 및 심각한 합병증의 발생 가능성이 있기 때문에 꾸준한 추적 관찰이 필요하다. 또한 가족적 발생을 할 수 있으므로 환자 가족 내 선별 검사를 해야 하며, 심근의 단독 비경화증의 정확한 빈도, 장기적 예후, 진단기준의 객관성을 확보하기 위하여 국내에서도 광범위한 다기관 연구가 필요하다.

  • Molar incisor malformation (MIM) has been introduced as a new type of dental anomaly. Currently, the morphological and histological characteristics of MIM are known; however, its etiology has not been clearly identified. To date, the long-term prognosis of first permanent molars (FPM) affected by MIM has rarely been reported, and few treatment guidelines have been established. The purpose of this case report was to present guidelines for the extraction of FPM affected by MIM, depending on the presence of the third molar. In patients with a third molar, spontaneous mesial shift of the posterior molars might be induced by extracting the FPM at an appropriate time, that is, when the second permanent molar is at an early furcation stage of the tooth. However, it is recommended that FPM be preserved for as long as possible if a third molar does not exist. When an FPM needs to be extracted, it is suggested to consider space maintenance.

  • Coronavirus disease 2019 (COVID-19) has become a major health burden worldwide, with over 450 million confirmed cases and 6 million deaths. Although the acute phase of COVID-19 management has been established, there is still a long way to go to evaluate the long-term clinical course or manage complications due to the relatively short outbreak of the virus. Pulmonary fibrosis is one of the most common respiratory complications associated with COVID-19. Scarring throughout the lungs after viral or bacterial pulmonary infection have been commonly observed, but the prevalence of post-COVID-19 pulmonary fibrosis is rapidly increasing. However, there is limited information available about post-COVID-19 pulmonary fibrosis, and there is also a lack of consensus on what condition should be defined as post-COVID-19 pulmonary fibrosis. During a relatively short follow-up period of approximately 1 year, lesions considered related to pulmonary fibrosis often showed gradual improvement; therefore, it is questionable at what time point fibrosis should be evaluated. In this review, we investigated the epidemiology, risk factors, pathogenesis, and management of post-COVID-19 pulmonary fibrosis.

  • Pancreatic cancer treatment has advanced. In particular, effective chemotherapy regimen development has fundamentally altered the therapeutic concept and strategy for pancreatic cancer treatment. Consequently, the prognosis of patients with pancreatic cancer has gradually improved. Conversion surgery for locally advanced pancreatic cancer may offer long-term survival or even a full recovery in some individuals. In contrast, metastatic pancreatic cancer has long been considered a surgical contraindication because aggressive surgical resection of the metastatic lesions does not prolong patient survival. Unexpectedly positive benefits of anticancer therapy in recent clinical experience were observed even with metastatic pancreatic cancer. To date, little evidence presented the success of surgical resection for metastatic pancreatic cancer treatment in such rare cases. However, hope and concern are growing that surgical intervention, even in patients with metastatic cancer, may result in favorable outcomes. Several studies suggested different surgical intervention effects depending on metastasis sites and patterns. Thus, this review summarizes the current status of surgery in the multidisciplinary treatment of oligometastatic pancreatic cancer and discusses future perspectives.

  • Purpose: Alpha-1 antitrypsin deficiency (A1ATD) in one of the most common genetic causes of liver disease in children. We aimed to analyze the clinical characteristics and outcomes of patients with A1ATD. Methods: This study included patients with A1ATD from five pediatric hepatology units. Demographics, clinical findings, genetics, and outcome of the patients were recorded (n=25). Results: Eight patients (32.0%) had homozygous PiZZ genotype while 17 (68.0%) had heterozygous genotype. Patients with PiZZ genotype had lower alpha-1 antitrypsin levels than patients with PiMZ genotype (37.6±7.7 mg/dL vs. 66.5±22.7 mg/dL, p=0.0001). Patients with PiZZ genotype were diagnosed earlier than patients with PiMZ genotype, but this was not significant (13±6.8 months vs. 23.7±30.1 months, p=0.192). Follow-up revealed the death of one patient (12.5%) with a homozygous mutation, and revealed that one patient had child A cirrhosis, five patients (62.5%) had chronic hepatitis, and one patient (12.5%) was asymptomatic. Nine of the 17 patients with a heterozygous mutation had chronic hepatitis (52.9%), two (11.7%) had child A cirrhosis, and six (35.2%) were asymptomatic. Overall, 18 (72%) of the 25 children had liver pathology in the long-term. Conclusion: Although prevalence is rare, patients with liver disorders should be checked for alpha-1 antitrypsin levels. Moreover, long-term follow-up is essential because most patients have a liver pathology.

  • 관절 연골 손상은 급성 손상과 만성 손상인 퇴행성 관절염으로 구분되며, 급성 손상은 연골 손상의 깊이에 따라서 미세 손상, 연골 골절, 골연골 골절의 세 종류로 구분할 수 있고 각 손상의 종류별로 서로 다른 양상의 치유 반응과 예후를 보인다. 만성 관절 연골 손상은 다양한 원인으로 인해서 발생하며 관절 연골의 전반적인 퇴행성 관절염의 형태를 보인다. 관절 연골 손상 시 초기 손상의 정도가 예후를 결정짓는데 가장 중요하고 이외에도 손상의 크기, 부위, 나이, 활동성, 비만 정도, 하지 정렬 상태등도 예후를 결정하는 중요한 요소들이다. 본 논문에서는 관절 연골 손상 시 발생하는 관절 연골 내의 병태 생리적 변화에 대하여 기술하고 비수술적인 치료 방법을 생역학적인 측면과 생물학적인 측면으로 구분하여 그 효과를 알아보고자 한다.

  • A four month old, intact female Jindo dog presented to the Veterinary Teaching Hospital of Kangwon National University with collapse. Physical examination revealed a heart rate of more than 200 beats per minute. Blood tests showed mild anemia and mild neutrophilia, while thoracic radiography and ultrasonography revealed no remarkable findings. Electrocardiography showed ventricular premature complexes (VPCs). The dog was diagnosed with congenital ventricular tachyarrhythmia. The condition was improved by lidocaine infusion. After 10 days, the dog was discharged from the hospital with a prescription of atenolol, pimobendan, diltiazem, furosemide, spironolactone, and L-carnitine. This dog is still alive after 31 months. However, progressive cardiac remodeling was confirmed on radiography and ultrasonography. Congenital ventricular tachyarrhythmia is rare in dogs, and the prognosis of reported cases is poor. This report describes the long-term successful management of a dog with congenital ventricular tachyarrhythmia.

  • Background: Few studies have evaluated the long-term impact of postoperative infectious complications in patients with non-small cell lung cancer (NSCLC). We aimed to determine the impact of infectious complications on long-term outcomes after surgical resection for NSCLC. Methods: We performed a retrospective study of 1,380 eligible patients who underwent pulmonary resection for NSCLC from 2003 to 2012. Complications were divided into infectious complications and non-infectious complications. Kaplan-Meier survival analysis was used to compare unadjusted 5-year cancer-specific survival (CSS) rates and recurrence-free survival (RFS) rates. Cox regression was used to determine the impact of infectious complications on 5-year CSS and RFS. Results: The rate of total complications and infectious complications was 24.3% and 4.3%, respectively. In the node-negative subgroup, the 5-year CSS and RFS rates were 75.9% and 57.1% in patients who had infectious complications, compared to 87.9% and 78.4% in patients who had no complications. Infectious complications were a negative prognostic factor for 5-year RFS (hazard ratio, 1.92; 95% confidence interval, 1.00-3.69; p=0.049). In the node-positive subgroup, the 5-year CSS rate and RFS were 44.6% and 48.4% in patients who had infectious complications, compared to 70.5% and 48.4% for patients who had no complications. Conclusion: Postoperative infectious complications had a negative impact on CSS and RFS in node-negative NSCLC. Our findings may help improve risk assessment for tumor recurrence after pulmonary resection for node-negative NSCLC.
