Background: The aim of this study was to evaluate the efficacy and tolerability of a gemcitabine, 5-fluorouracil and leucovorin (GEMFUFOL) chemotherapy regimen as first line treatment of metastatic biliary tract cancer. Materials and Methods: All patients received folinic acid $400mg/m^2$ on day 1, 5-fluorouracil bolus $400mg/m^2$ on day 1, IV infusion of 5-fluorouracil $2400mg/m^2$ over 46 hours, and gemcitabine $1250mg/m^2$ on day 1. Results: A total of 29 patients with metastatic biliary tract cancer received GEMFUFOL regimen as the firstline treatment. The mean follow-up was 22.1 months (95%CI, 12.5-31.8). One patient (3.4%) achieved complete response, 5 (17.2%) had partial response, and 4 (13.8%) had stable disease. The median progression-free survival was 3.3 months (95%CI, 2.9-3.7), and the median overall survival was 8.8 months (95%CI, 3.5-14). The 1-year and 2-year survival rates were 58.6% and 30%, respectively. Grade 3 and 4 toxicity included neutropenia in 4 patients (13.7%), thrombocytopenia in 2 (6.8%), anemia2 (6.8%), and alopecia in 1 (3.4%). Two patients (6.8%) developed febrile neutropenia. A dose reduction was achieved in 8 patients (27.6%) while 5 patients had extended-interval dosage (17.2%) for toxicity. Conclusions: The GEMFUFOL chemotherapy regimen was generally efficacious and tolerable as a first-line treatment of metastatic biliary tract cancer.

Purpose: This survey was aimed to examine the current dietary restrictions practices for neutropenic patients among hospitals with 500 and more beds. Methods: Self-administered questionnaires were sent to 100 head or charge nurses of oncology or hemato-oncology wards by mail during October 2009, and 51 questionnaires were returned. The data were analyzed with descriptive statistics using SPSS (WIN version 12.0). Results: Of the hospitals surveyed, 47.1% (n=24) had guidelines on the dietary restrictions, and 80.4% (n=41) placed patients with neutropenia on restricted diets. The major decisional criteria of the dietary restriction was absolute neutrophil count (30.5%) and cooking status (29.2%). The most commonly restricted foods were raw fish or fresh meat (98.0%), uncooked intestine (98.0%), raw eggs (98.0%), draught beer (96.1%), and fresh fruits or vegetables (86.3%). Conclusion: The results showed variation in pattern of dietary restrictions and lower rate of guideline among hospitals, so that the need for the standard dietary restriction guideline is high. However, the role of diet in the development of infection in neutropenic patients is still unclear, which makes it difficult to establish dietary restriction guideline. Therefore, additional research are required to identify the relationship between dietary factors and infections.

Central Cancer Registry of Korean National Cancer Center in 1999 reported that mortality from lung cancer is higher than mortality from stomach cancer or hepatocellular carcinoma in Korean male. Lung cancer is classified into small cell cancer and non-small cell lung cancer (NSCLC), and NSCLC patients account for $70\%$ of the whole lung cancer patients. The purpose of this study was to evaluate the efficacy and toxicity of docetaxel and cisplatin combination in Korean patients with NSCLC. All patients who had received the combination therapy of docetaxel and cisplatin for histologically confirmed NSCLC in Ajou University Hospital between 2000. $2\~2001$. 4 were retrospectively evaluated for the responses and toxicities of that combination therapy. Nineteen patients were treated with docetaxel 75 $mg/m^2$ on Day 1 and cisplatin 25 $mg/m^2$ on Day 1-3 every 4 weeks. The response for combination regimen was evaluated by CT scans after 2 or 3 cycles of treatments. Seventeen patients were evaluated for the responses and the 19 patients far the toxicities. Among the 19 patients (14 men and 5 women), there were one patient $(5.3\%)$ with stage I disease, 4 patients $(21.1\%)$ with stage III disease, and 14 patients $(73.1\%)$ with stage IV disease. Of the 17 patients who were evaluable for response, complete response (CR) was not observed in any patient while partial response (PR) was observed in 5 patients $(29.4\%)$. The overall response rate (CR+PR) was $29.4\%$. Stable disease (SD) was observed in 11 patients $(64.7\%)$ and progressive disease (PD) in 1 patient $(5.9\%)$. The toxicities were graded by NCI (National Cancer Institute) Common Toxicity Criteria for the evaluable 70 cycles. Grade 3 or 4 neutropenia occurred in 53 cycles $(76\%)$. Four patients were hospitalized due to febrile neutropenia. The combination chemotherapy of docetaxel and cisplatin was effective as NSCLC treatments, however, the regimen must be administered carefully due to its hematological side effects.

Background/Aims: Data on dexamethasone, cytarabine, and cisplatin (DHAP) as a mobilization regimen, compared to high-dose cyclophosphamide (HDC), for up-front autologous stem cell transplantation (ASCT) in non-Hodgkin's lymphoma (NHL) is limited. Methods: Consecutive patients with aggressive NHL treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or rituximab-CHOP who underwent chemomobilization using HDC or DHAP plus granulocyte-colony stimulating factor (G-CSF) for up-front ASCT were enrolled from three institutions between 2004 and 2014. Results: Ninety-six patients (57 men) were included. Sixty-five patients (67.7%) received HDC; and 31 (32.3%), DHAP. The total CD34+ cells mobilized were significantly higher in patients receiving DHAP (16.1 vs. $6.1{\times}10^6/kg$, p = 0.001). More patients achieved successful mobilization with DHAP (CD34+ cells ${\geq}5.0{\times}10^6/kg$) compared to HDC (87.1% vs. 61.5%, respectively; p = 0.011), particularly within the first two sessions of apheresis (64.5% vs. 32.3%, respectively; p = 0.003). Mobilization failure rate (CD34+ cells < $2.0{\times}10^6/kg$) was significantly higher in patients receiving HDC (20.0% vs. 3.2%, p = 0.032). On multivariate analysis, the DHAP regimen (odds ratio, 4.12; 95% confidence interval, 1.12 to 15.17) was an independent predictor of successful mobilization. During chemomobilization, patients receiving HDC experienced more episodes of febrile neutropenia compared to patients receiving DHAP (32.3% vs. 12.9%, p = 0.043). Conclusions: The DHAP regimen was associated with a significantly higher efficacy for stem cell mobilization and lower frequency of febrile neutropenia. Therefore, DHAP plus G-CSF is an effective for mobilization in patients with aggressive NHL who were candidates for up-front ASCT.

Background: Docetaxel is one of the standard treatments for advanced non-small cell lung cancer. Docetaxel is usually administered in a 3-week schedule, but there is significant toxicity. In this phase II clinical study, we investigated the efficacy and safety of a 4-weekly schedule of docetaxel monotherapy, as first-line chemotherapy for advanced squamous cell carcinoma in elderly lung cancer patients. Methods: Patients with stage IIIB/ IV lung squamous-cell carcinoma age 70 or older, that had not undergone cytotoxic chemotherapy were enrolled. Patients received docetaxel $25mg/m^2$ on days 1, 8, and 15, every 4 weeks. Primary endpoint was the objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results: A total of 19 patients were enrolled. Among 19 patients, 17 were for evaluated efficacy and safety. In the intent-to-treat population, ORR and disease control rate (DCR) were 11.8% and 47.1%, respectively. In the response evaluable population, ORR was 16.7% and DCR was 66.7%. Median PFS and OS were 3.1 months and 3.3 months, respectively. There were three adverse grade 3/4 events. Grade 1 neutropenia was reported in one patient. Conclusion: Our data failed to demonstrate efficacy of a 4-weekly docetaxel regimen, in elderly patients with a poor performance status. However, incidence of side effects, including neutropenia, was lower than with a 3-week docetaxel regimen, as previously reported.

Purpose: In this study, we investigated the clinical features and prognostic factors of early-onset sepsis (EOS) in neonatal intensive care unit (NICU) patients. Methods: A retrospective analysis was conducted on medical records from January 2010 to June 2017 (7.5 years) of a university hospital NICU. Results: There were 45 cases of EOS (1.2%) in 3,862 infants. The most common pathogen responsible for EOS was group B Streptococcus (GBS), implicated in 10 cases (22.2%), followed by Escherichia coli, implicated in 9 cases (20%). The frequency of gram-positive sepsis was higher in term than in preterm infants, whereas the rate of gram-negative infection was higher in preterm than in term infants (P<0.05). The overall mortality was 37.8% (17 of 45), and 47% of deaths occurred within the first 3 days of infection. There were significant differences in terms of gestational age (26.8 weeks vs. 35.1 weeks) and birth weight (957 g vs. 2,520 g) between the death and survival groups. After adjustments based on the difference in gestational age and birth weight between the 2 groups, gram-negative pathogens (odds ratio [OR], 42; 95% confidence interval [CI], 1.4-1,281.8) and some clinical findings, such as neutropenia (OR, 46; 95% CI, 1.3-1,628.7) and decreased activity (OR, 34; 95% CI, 1.8-633.4), were found to be associated with fatality. Conclusion: The common pathogens found to be responsible for EOS in NICU patients are GBS and E. coli. Gram-negative bacterial infections, decreased activity in the early phase of infection, and neutropenia were associated with poor outcomes.

목 적 : 신생아 호중구 감소증이 합병된 신생아 패혈증 환아의 치료에 있어서 부가적으로 rhG-CSF(recombinant human granulocye colony-stimulating factor)를 투여함에 있어서 서로 다른 용량의 rhG-CSF를 투여함으로써 나타나는 신생아 패혈증에 합병된 호중구 감소증의 치료와 환아들의 생존율에 미치는 영향을 평가, 비교하려고 하였다(group I/II형 연구). 방 법: 1995년 10월부터 1996년까지 신생아 호중구 감소증이 합병된 신생아 패혈증 환아는 모두 10명으로 이들에게는 $10{\mu}g/kg$을 피하주사 하였고(rhG-CSF $10{\mu}g/kg$ 투여군), 1996년 10월부터 1997년 9 월까지는 신생아 호중구 감소증이 합병된 신생아 패혈증 환아는 모두 12명으로 이들에게는 rhG-CSF를 $5{\mu}g/kg$ 피하주사 하였다(rhG-CSF $5{\mu}g/kg$ 투여군). 각 군의 호중구 증가 정도와 임상적 결과를 서로 비교하였다. 결 과 : RhG-CSF $10{\mu}g/kg$ 투여군은 조발형 신생아 패혈증 1명과 지발형 신생아 패혈증 9명으로 이루어졌고, 모두에게 호중구 감소증이 합병되었다. rhG-CSF $5{\mu}g/kg$ 투여군은 조발형 신생아 패혈증 1명과 지발형 신생아 패혈증 11명이 대상이 되었고, 이들 모두 호중구 감소증이 합병되었다. 두 군간에 출생체중, 재태주령, 항생제 사용, 신생아 패혈증 시기에 기계적 환기요법 투여, 승압제로 dopamine 투여 또는 다른 지지적 요법의 투여에 있어서 차이가 없었다. rhG-CSF 투여 전의 순 호중구 수(ANC)는 rhG-CSF $10{\mu}g/kg$ 투여군이 $1,065{\pm}89$($mean{\pm}SEM$), $5{\mu}g/kg$ 투여군이 $1,053{\pm}131$로 차이가 없었다. 투여 후의 ANC의 증가는 rhG-CSF $10{\mu}g/kg$ 투여군과 $5{\mu}g/kg$ 투여군에서 각각 투여 후 24시간에 7배, 6배, 투여 후 48시간에 10배, 6배, 투여 후 72시간에 8배, 4배, 투여 후 120시간에 8배, 4배로 투여 전에 비하여 두 군 모두에서 각 시간에 의미 있는 증가를 보였다(repeated measure ANOVA와 Kruskall-Wallis test, within subjects effect). 그러나 두 군 간의 차이는 투여 후 48시간에 ANC 최고치에서만 의미 있는 차이를 보였다(student t-test와 Wilcoxon rank sum test). 단핵구 수도 이 기간 동안 의미 있게 증가하였으나 정상범위를 넘지는 않았다. rhG-CSF $10{\mu}g/kg$ 투여군에서 1명의 환아가 자의 퇴원하였고, 1명의 환아가 사망하여 신생아 패혈증에서 회복하여 문제없이 퇴원한 생존율은 자의 퇴원 환아를 제외한 9명 중 8명으로 88.9％였고, rhG-CSF $5{\mu}g/kg$ 투여 군은 12명 중 10명이 생존하여 생존율은 83.3%였다. 두 군 모두에서 특별한 독성이나 부작용은 관찰되지 않았다. 결 론 : RhG-CSF의 투여는 호중구 감소증이 합병된 극심한 신생아 패혈증 환아에서 호중구의 증가를 일으켰다. 두가지 투여 용량에 따르는 효과는 거의 동일하였으며, 단지 투여 후 48시간에 ANC 최고치에서만 의미 있는 차이가 있었다. 두 군의 생존율은 80%이상이었다. 이와 같은 호중구 감소증이 합병된 신생아 패혈증에서 rhG-CSF의 투여 효과는 골수 억압이나 호중구 소모에 의하여 호중구 감소증이 합병된 신생아 패혈증에서 시기적으로 적절히 투여하면 효과적인 치료를 이룰 수 있다는 것을 시사한다. 향후 rhG-CSF의 효능과 부작용에 대하여 무작위 대조실험이 필요시 된다.

The Schwachman-Diamond syndrome is an autosomal recessive syndrome(1/20,000 births), consisting of pancreatic insufficiency, neutopenia, which may be intermittent, neutrophil chemotaxis defects, metaphyseal dysostosis, failure to thrive and short stature. Patients present in infancy with poor growth and grease, foul-smelling stools that are characteristic of malabsorption. These children can be readily differentiated from those with cystic fibrosis by their normal sweat chloride levels, lack of the cystic fibrosis gene, and characteristic metaphyseal lesions. Pathologically, the pancreatic acini are replaced by fat with little fibrosis. The neutropenia may be cyclic. Recurrent pyogenic infections otitis media, pneumonia, dermatitis(fig 1), sepsis are common and a frequent cause of death. In dental examination, these patients had a poor oral hygine and moderate generalized marginal gingivitis, also show delayed primary tooth exfoliation and oral development. This report illustrates a case that pancreatic agenesis 6 yeas-old boy with various esthetic dental problems has been served the esthetic dental restoration of 6 years.

Background: This analysis was conducted to evaluate the efficacy and safety of temozolomide based chemotherapy in treating patients with glioma. Methods: Clinical studies evaluating the efficacy and safety of temozolomide based regimens for patients with glioma were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: In temozolomide based regimens, 5 clinical studies including 152 patients with advanced glioma were considered eligible for inclusion. Four clinical studies included temozolomide. Systematic analysis suggested that, in all patients, pooled CR was 21% (32/152), and PR was 21% (32/152). Grade 3/4 toxicity included neutropenia, thrombocytopenia, and anemia. No grade 3 or 4 renal or liver toxicity was observed. No treatment related death occurred with temozolomide based treatment. Conclusion: This systematic analysis suggests that temozolomide based regimens are associated with mild response rate and acceptable toxicity for treatment of glioma patients.

Mucormycosis is a rare but fatal fungal infection with low survival rate in immune-compromised patients. It is caused by a fungus belonging to the Mucoraceae family of the Zygomycetes class. Mucormycosis is classified as rhino-orbital-cerebral, pulmonary, cutaneous, gastrointestinal, disseminated, and miscellaneous types according to its clinical manifestations. Early diagnosis and treatment along with correction of the underlying medical condition is important for favorable results. This case presentation describes mucormycosis involving the anterior maxillary region in a leukemic patient with prolonged neutropenia. The patient benefited from a timely biopsy and immediate treatment with amphotericin B, and was successfully managed with an interdisciplinary team approach consisting of dental and several medical specialists.
