Hereditary hemorrhagic telangiectasia (HHT, Osler-Weber-Rendu disease) is a rare autosomal dominant disease characterized by heterogenous multisystemic dysplasia of the vascular tissue. Prevalence of HHT is 1 in 5,000~8,000. HHT commonly presents with recurrent epistaxis, but may have more serious consequences if visceral vascular beds are involved. Approximately 30~50% of HHT cases also present with pulmonary arteriovenous malformation (PAVM). Spontaneous hemothorax is less common, and PAVM is one of the causes leading to hemothorax. Our case involved an 18-year-old female who had suddenly developed right chest pain. The reason for chest pain was due to right spontaneous hemothorax accompanied by PAVM in the right middle lobe. The patient was additionally diagnosed with HHT upon examination of her family history, specifically through her mother's symptom that included recurrent epistaxis and mucosal telangiectasia.

Purpose: This systematic review aims to identify factors associated with risk-reducing salpingo-oophorectomy (RRSO), including the uptake rate and decision timing, among women at high risk for hereditary breast and ovarian cancer (HBOC). Methods: We found 4,935 relevant studies using MEDLINE, Embase, CINAHL, and PsycINFO on July 6, 2020. Two authors screened the articles and extracted data. Twenty-four studies met the inclusion criteria. Quality assessment of articles was conducted using the Risk of Bias for Nonrandomized Studies tool. Results: Five types of factors were identified (demographic factors, clinical factors, family history of cancer, psychological factors, and objective cancer risk). The specific significant factors were older age, having child(ren), being a BRCA1/2 carrier, mastectomy history, perceived risk for ovarian cancer, and perceived advantages of RRSO, whereas objective cancer risk was not significant. The uptake rate of RRSO was 23.4% to 87.2% (mean, 45.2%) among high-risk women for HBOC. The mean time to decide whether to undergo RRSO after BRCA testing was 4 to 34 months. Conclusion: RRSO decisions are affected by demographic, clinical, and psychological factors, rather than objective cancer risk. Nonetheless, women seeking RRSO should be offered information about objective cancer risk. Even though decision-making for RRSO is a complex and multifaceted process, the psychosocial factors that may influence decisions have not been comprehensively examined, including family attitudes toward RRSO, cultural norms, social values, and health care providers' attitudes.

성장기 부정교합 환자의 치료시 다양한 악안면 성장은 치료성패의 중요한 요소이다. 따라서 치료를 시작하기 전에 안면성 장을 예측하는 것은 매우 중요하다. 본 연구는 III급 부정 교합을 보이 는 아동에서 성장을 예측할 수 있는 방법들 중의 하나로 두부방사선 계측사진 분석을 통해 유전적 요소의 관련여부를 알아보고자 50가족에서 부모자식간의 악안면 형태의 상관관계를 통계학적으로 분석하였다. 또한 자식과 부모간의 지문의 형태적 연관성을 조사하고 부모자식간의 악안면 형태와 지문의 형태적 연관성과의 유전적 상관관계를 조사하여 다음과 같은 결론을 얻었다. 1 부모자식간의 악안면 형태에서 치성관계보다는 악골관계에서 더 유전성향이 높았으며 아버지가 어머니에 비해 자식의 악골관계에 더 영향을 주었다. 2. 자식의 지문 형태는 아버지보다는 어머니와의 연관성이 더 높게 나타났다. 3. 부모와 자식간의 지문과 악안면 형태에서 유전적 상관관계가 있었으며(P<0.05-0.01), 딸보다는 아들에게서 연관성이 더 높게 나타났다.

Background: Cancer genetics have gained public attention dramatically. Everyday physicians and nurses use the knowledge of cancer genetics in their practices. Despite the importance of the knowledge of the health care providers on cancer genetics, there is a paucity of literature investigating the levels of knowledge about cancer genetics among health care providers. Purpose: This study aimed to describe the Korean physicians' current knowledge level about hereditary breast and ovarian cancer (HBOC). Method: This nation-wide survey used a 15-item questionnaire which is modified from the Breast Cancer Genetic Counseling Knowledge Questionnaire originally developed by Erblich et al.(2005). One hundred and forty-four physicians participated in this survey from October 1, 2006 to March 31, 2007. Result: Physicians' knowledge level about hereditary breast cancer was 11.94 (S.D=2.46). Physicians with short-term careers (less than one year), the position of Intern, or who were involved in breast or ovarian cancer care demonstrated the highest knowledge about HBOC. Conclusion: Genetic courses in medical education seemed to contribute to the high level of physicians' genetic knowledge. Also, nursing discipline needs to incorporate genetics or genetic counseling courses into the formal educational curriculum in order to deliver up to date cancer care services which are sensitive to ever-changing cancer genetic information.

In this paper we will define correct module and strongly correct module. We can have some basic results about those modules. And we will show that M is a graded correct R-module if and only if $M_e$ is a correct $R_e$-module.

By introducing the notion of a generalized normal state space, we give a necessary and sufficient condition for that there exists a unital normal completely map from a von Neumann algebra into another, in terms of their generalized normal state spaces.
