Background: The complication rate of fungal disease is higher among patients with hematological malignancies. We investigated the clinicobacteriological outcomes of resected pulmonary fungal infections complicating hematological malignancies. Methods: Between 2001 and 2017, 21 patients with pulmonary fungal infections complicating hematological malignancies underwent resection, and their clinical records and survival were retrospectively reviewed. Results: The median age of the patients was 47 years, and 13 were male. The histological diagnoses were pulmonary aspergillosis (19 cases), mucormycosis (1 case), and cryptococcosis (1 case). The indications for surgery were resistance to antifungal therapy and the necessity of surgery before hematopoietic stem cell transplantation in 13 and 8 cases, respectively. The diagnoses of the hematological malignancies were acute myelogenous leukemia (10 cases), acute lymphocytic leukemia (5 cases), myelodysplastic syndrome (3 cases), and chronic myelogenous leukemia, malignant lymphoma, and extramedullary plasmacytoma (1 case each). The surgical procedures were partial resection (11 cases), segmentectomy (5 cases), lobectomy (4 cases), and cavernostomy (1 case). The size of the lesions was 0.9-8.5 cm. Fourteen cases had cavitation. There were no surgical-related deaths or fungal progression. Conclusion: Pulmonary fungal infections are resistant to treatments for hematological malignancies. Since the treatment of the underlying disease is extended and these infections often recur and are exacerbated, surgery should be considered when possible.

소아 악성종양환아들의 완치를 위한 조혈모세포이식술이 최근 널리 이루어지고 있다. 하지만 높은 치료율과 더불어 이의 부작용 또한 많이 보고되고 있다. 본 연구에서는 소아에서 조혈모세포이식술 이후의 급성 신질환의 임상적인 특성과 결과에 대해 알아보고자 하였다. 1995년 9월부터 2009년 4월까지 영남대학교 부속병원 소아청소년과에서 조혈모세포이식을 시행한 53명의 환자들을 대상으로 하였다. 조혈모세포이식 3개월 후의 사구체여과율을 계산하여 신장의 기능이 25% 이상 감소한 '조기 신기능 감소군'과 25% 미만 감소한 '조기 신기능 비감소군' 두 군으로 나누어 의무기록을 후향적으로 분석하였다. 환아의 원인 질환은 급성 백혈병과 신경모세포종이 각각 23명과 13명으로 가장 많았고, 그 외 뇌종양 및 기타 고형 종양이 6명, 재생불량성 빈혈이 4명, 악성 림프종이 4명, 골수이형성 증후군이 2명, 선천성 면역결핍질환이 1명이었다. 조혈모세포이식 3개월 후 25% 이상의 사구체여과율이 감소한 환아는 18명이었다. '조기 신기능 감소군'과 '조기 신기능 비감소군'은 각각 18명과 35명이었고, 이식세포 공급원은 제대혈(n=11)이 4명과 7명, 골수(n=16)는 8명과 8명, 자가 말초혈액(n=26)은 6명과 20명으로 차이는 없었다. 골수 및 제대혈 이식을 시행한 27명의 환아에서 급성 이식편대숙주반응은 신기능 감소군과 비감소군에서 차이를 보이지 않았다. 모든 환아는 전처치법 중 1가지 이상의 신독성 항암제를 투여받았으며 전신방사선조사 및 항흉선세포글로불린을 포함한 전처치법에 따른 두 군의 차이는 없었다. 사망한 환아는 '조기 신기능 감소군'과 '조기 신기능 비감소군'이 각각 12명과 10명이었고, '조기 신기능 감소군'에서 사망환아의 비율이 더 많았고, 사망의 원인으로는 감염, 급성 신부전, 재발 등이었고 '조기 신기능 비감소군'에 비해서 '조기 신기능 감소군'에서 급성 신부전이 많았다. 하지만 신장기능의 저하정도에 따라서는 사망한 환아는 차이를 보이지 않았다. 이번 연구에서는 소아에서 조혈모세포이식 3개월 후의 조기 신기능 저하는 18명이 있었으며 조혈모세포이식 후 발생하는 합병증 중 하나인 급성 이식편대숙주반응과 관련이 없었으며 이식세포 공급원과도 관련이 없었다. 조기 신기능 저하를 보인 환아에서 사망한 환아가 많았고, 신장기능 저하가 중요한 사망 원인이었다. 생존한 조기 신기능 저하군의 환아는 모두 신기능을 회복하였으며, 이식 12개월 후 후기 신기능 저하는 1명으로 이식의 합병증과는 관련이 없었으나 이후 이식 6년째에 재발로 사망하였다.

Aplastic anemia (AA) is a serious hematologic disease characterized by hypocellular bone marrow and deficient production of erythrocytes, granulocytes and platelets. Serious complications such as uncontrolled bleeding and bacteremia can occur. A case of severe AA are presented with dental considerations. A 4-year-old boy had been referred from Seoul National University Hospital for dental examination before the hematopoietic stem cell transplantation (HSCT). Treatments were planned under general anesthesia, due to the poor compliance. Following medical consult, dental treatments were performed after platelet transfusion and antibiotic prophylaxis. Postoperatively, neither significant bleeding nor complictation was observed. On the time of the treatment planning. the anesthesiologist and dentist should perform a complete hematological assessment. It is imperative not only platelet counts but also other leukocyte counts are under safe boundaries. It is mandatory to follow strict aseptic precautios for all anesthetic and surgical maneuvers. In severe thrombocytopenic patients, platelet transfusion should be considered. Also, it is recommended to establish a good oral hygiene.

Background: We conducted a study exploring the clinical safety and efficacy of decitabine in patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), combined with a complex karyotype. Materials and Methods: From April 2009 to September 2013, a total of 35 patients with AML/MDS combined with a complex karyotype diagnosed in the First Affiliated Hospital of Soochow University were included for retrospective analysis. All patients were treated with decitabine alone ($20mg/m^2$ daily for 5 days) or combination AAG chemotherapy (Acla 20mg qod*4d, Ara-C $10mg/m^2$ q12h*7d, G-CSF $300{\mu}g$ qd, the dose of G-CSF adjusted to the amount in blood routinely). Results: In 35 patients, 15 exhibited a complete response (CR), and 6 a partial response (PR), the overall response rate (CR+PR) being 60% (21 of 35). Median disease-free survival was 18 months and overall survival was 14 months. In the 15 MDS patients with a complex karyotype, the CR rate was 53.3% (8 of 15); in 20 AML patients with complex karyotype, the overall response rate was 65% (13 of 20). The response rate of decitabine alone (22 cases) was 56.5% (13 of 22), while in the combination chemotherapy group (13 cases), the effective rate was 61.5% (8 of 13)(P>0.05). There are 15 patients with chromosome 7 aberration, after treatment with decitabine, 7 CR, 3 PR, overall response rate was 66.7% (10 of 15). Of 18 patients with 3 to 5 kinds of chromosomal abnormalities, 66.7% demonstrated a response; of 17 with more than 5 chromosomal abnormalities, 52.9% had a response. In the total of 35 patients, with one course (23 patients) and ${\geq}$two courses (12 patients), the overall response rate was 40.9% and 92.3% (P<0.05). Grade III to IV hematological toxicity was observed in 27 cases (75%). Grade III to IV infections were clinically documented in 7 (20%). Grades I to II non-hematological toxicity were infections (18 patients), haematuria (2 patients), and bleeding (3 patients). With follow-up until September 2013, 7 patients were surviving, 18 had died and 10 were lost to follow-up. In the 6 cases who underwent allogeneic hematopoietic stem cell transplantation (HSCT) all were still relapse-free survivors. Conclusions: Decitabine alone or combination with AAG can improve outcome of AML/MDS with a complex karyotype, there being no significant difference decitabine in inducing remission rates in patients with different karyotype. Increasing the number of courses can improve efficiency. This approach with fewer treatment side effects in patients with a better tolerance should be employed in order to create an improved subsequent chance for HSCT.
