  • 목적: 석회화 건막 섬유종은 소아 및 청소년층에서 수장부를 가장 많이 침범하는 양성이나 공격적 성향을 띈 섬유성 종양이다. 저자들은 최근에 15세 소년의 수부에 발생한 석회화 건막 섬유종의 치료를 경험하였기에 이를 문헌 고찰과 함께 보고하고자 한다. 증례: 15세 소년이 좌수의 소지구 부위에 재발하는 종물을 주소로 내원하였으며 이 소년은 7년전에 타 병원에서 국소 마취 하에 동일 부위에 발생한 종물을 제거한 기왕력을 가지고 있었다. 종물은 단단하였으며 압통이 있었다. 단순 방사선 촬영상에는 종물 내에 다소성으로 산재된 미세 석회 침착이 보였다. 수술 소견상 종물은 주변과 명확히 구분되지 않았으며 단단하고 옅은 회색빛의 석회화를 동반한 침습성의 결절성 형태를 보였으며 가이언 관내의 척골 신경과 척골 동맥이 바로 인접하고 있었다. 수술 후 제거한 종물을 현미경적으로 관찰한 결과 종물은 많은 석회 침착이 되어 있으면서 이형성 연골양 분화를 보이는 조직이 중간 중간에 섞여 있는 빽빽한 섬유 조직의 증식으로 이루어져 있었고 주변부는 명확히 경계 지어지지 않으며 분엽상을 보이고 있었다. 결론: 이 질환에 있어서 가장 바람직한 치료법은 기능적인 면과 주요 조직을 보존할 수 있는 한도내에서 광범위 절제를 시행하는 것이며 이렇게 치료하더라도 많게는 50 %이상의 재발율이 보고되고 있는 실정이다.

  • Seaweeds provide habitats in which marine animals can spawn and develop, and serve as a food supply for algaegrazing species such as sea urchins and abalone. Recently, seaweed species have disappeared from coastal ecosystems, leaving barren ground, defined as habitats that have lost their algae forests and where coralline algae containing calcium carbonate components have become encrusted on rocks. The biological causes of barren ground include grazing by herbivores and excessive seaweed harvest. The environmental harm caused by the spread of barren ground includes accelerated eutrophication following the reduction in seaweed, which plays an important role in oceanic purification. In the present study, we identified the relationships between various seaweed species and the occurrence of barren ground. Subtidal benthic macroalgal flora and community structure were observed seasonally on barren ground along vertical transects of rocky shores of Bihwa, Samchuck, and the east coast of Korea from February to November 2006. Fifty-eight seaweed species were identified, including 7 green, 15 brown, and 36 red algae species. There were between 6 and 28 species among seasons. Over the whole study period, average seaweed biomass (g wet wt $m^{-2}$) was 241.90 g, with a seasonal range of 25.26 to 760.34 g. Seaweed biomass declined with increasing seawater depth and ranged between 91.26 and 422.08 g. The vertical distribution of algae was characterized by Undaria pinnatifida and Sargassum honeri at 5 m, S. honeri and U. pinnatifida at 10 m, and U. pinnatifida and Agarum clathratum at 15 m depth. Seasonal patterns in community indices were not found. Community indices showed different patterns along vertical shoreline gradients; the dominance index increased but the richness, evenness, and diversity indices decreased with seawater depth. Sea urchin density was 8 to 24 individ. $m^{-2}$ in Bihwa. These urchin populations had significantly aggregated spatial patterns and recurrent destructive grazing appeared to be occurring.

  • This report on the $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine comes to conclude, through the study of the Oriental- Western medical references, as follow; 1. First, $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine had some concurrencies that both the two symptoms have appeared severe and recurrent headache and more often to the female. 2 Many of them e.g. Sensory disturbance, Vertigo, Nausea, Vomiting, Tinnitus etc. in the prodrome and main symptom of $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine were identical, especially the symptom of the $f{\bar{e}}ng\;t{\acute{a}}n\;t{\acute{o}}u\;t{\grave{o}}ng$ was similar to the prodrome of the Migraine. We could find out the semilarity of the symptoms through that Migraine is proximately set in unilateral, and $Pi{\bar{a}}nT{\acute{o}}u\;f{\bar{e}}ng$ is so called alias $B{\grave{a}}n\;bi{\bar{a}}n\;t{\acute{o}}u\;t{\grave{o}}ng$. 3. The pathogeny of $T{\acute{o}}u\;f{\bar{e}}ng$ include the case of ‘$f{\bar{e}}ng\;xi{\acute{e}}\;r{\grave{u}}\;n{\bar{a}}o$’, the patient feeling weak condition, $T{\acute{a}}n,\;T{\acute{a}}nshi,\;T{\acute{a}}nhu{\breve{o}},\;Y{\grave{u}}q{\grave{i}}$, etc. and, ‘$t{\acute{a}}n\;zhu{\grave{o}}\;sh{\grave{a}}ng\;y{\acute{a}}o$’, ‘$G{\bar{a}}n\;y{\acute{a}}ng\;hu{\grave{a}}\;f{\bar{e}}ng$’. There were variable that $F{\bar{e}}ng,\;Xu{\grave{e}},\;F{\bar{e}}ngr{\grave{a}},\;F{\bar{e}}ngx{\bar{u}},\;Xu{\grave{e}}x{\bar{u}},\;Hu{\check{o}}$ in the left, and $t{\acute{a}}n,\;R{\grave{e}},\;t{\acute{a}}nr{\grave{e}},\;Qir{\acute{a}}$ in the right partial pathogeny. It was referred $Sh{\grave{a}}o\;y{\acute{a}}ng\;j{\bar{i}}ng$, $Ju{\acute{e}}\;y{\bar{i}}n\;j{\bar{i}}ng$, $Y{\acute{a}}ng\;m{\acute{i}}ng\;j{\bar{i}}ng$, $T{\grave{a}}i\;y{\acute{a}}ng\;j{\bar{i}}ng$ in connection with the Meridian system. And otherwise the primary cause of Migraine is still unknown to us. Heredity is probably important, but the mode of transmission is uncertain. Recently, the important assumption is the vasomotor change caused by vasoconstrictors like that norepinephrine, epinephrine, and serotonin etc.

  • While imported falciparum malaria has been increasingly reported in recent years in Korea, clinicians have difficulties in making a clinical diagnosis as well as in having accessibility to effective anti-malarial agents. Here we describe an unusual case of imported falciparum malaria with severe hemolytic anemia lasting over 2 weeks, clinically mimicking a coinfection with babesiosis. A 48-year old Korean man was diagnosed with severe falciparum malaria in France after traveling to the Republic of Benin, West Africa. He received a 1-day course of intravenous artesunate and a 7-day course of Malarone (atovaquone/proguanil) with supportive hemodialysis. Coming back to Korea 5 days after discharge, he was readmitted due to recurrent fever, and further treated with Malarone for 3 days. Both the peripheral blood smears and PCR test were positive for Plasmodium falciparum. However, he had prolonged severe hemolytic anemia (Hb 5.6 g/dl). Therefore, 10 days after the hospitalization, Babesia was considered to be potentially coinfected. A 7-day course of Malarone and azithromycin was empirically started. He became afebrile within 3 days of this babesiosis treatment, and hemolytic anemia profiles began to improve at the completion of the treatment. He has remained stable since his discharge. Unexpectedly, the PCR assays failed to detect DNA of Babesia spp. from blood. In addition, during the retrospective review of the case, the artesunate-induced delayed hemolytic anemia was considered as an alternative cause of the unexplained hemolytic anemia.

  • Bmi1은 PcG 단백의 일종으로 PRC를 구성하는 성분이다. Bmi1에 관한 초기의 연구는 주로 암세포에서의 역할에 집중되었고, 그 결과 Bmi1은 암세포의 증식과 생존에 중요한 역할을 하는 것으로 받아들여지고 있다. 그러나, 최근의 연구 결과 Bmi1은 퇴행성 신경계 질환이 있는 뇌에서 발현이 감소되어 있고 미토콘드리아의 기능과 활성 산소 수준을 조절하는 것으로 알려져 있다. 본 연구에서는 Bmi1 발현 저하 동물을 이용하여 간질에서 Bmi1의 약물 치료 표적 가능성을 밝히고자 하였다. Bmi1의 발현은 pilocarpine에 의한 경련중첩증 이후 해마의 CA1, CA3 그리고 치상회에서 뚜렷하게 증가하였다. 경련 양상을 볼 때 경련중첩증이 유도되는 비율은 Bmi1+/+와 Bmi1+/- 생쥐에서 각각 43.14%와 53.57%로 나타났다. 그러나, 치사율과 해마의 신경세포 손상에는 두 군 간에 통계적으로 유의한 차이를 보이지 않았다. 경련중첩증 유도 2개월 후에 나타난 간질 경련의 빈도수는 통계적 유의성은 없었으나 Bmi1+/- 생쥐에서 약 50% 낮게 나타났다. 반면, 이끼섬유발아는 Bmi1+/- 생쥐에서 통계적으로 유의하게 증가하였다. 이러한 결과를 종합하면, Bmi1의 발현이 감소할 때 pilocarpine에 의한 경련 유도와 이끼섬유발아가 증가함을 보여준다.

  • Objective: The aim of this study was to explore the potential adverse effect of spontaneously decreasing serum estradiol (SE) levels on in vitro fertilization (IVF) outcomes. Methods: This retrospective single-subject study analyzed IVF cycles conducted at a hospital IVF unit between 2010 and 2017. Overall, 2,417 cycles were analyzed. Only cycles with spontaneously decreasing SE before human chorionic gonadotropin (hCG) triggering were included. Each patient served as her own control, and subsequent cycles were analyzed for recurrent SE decreases. The main outcome was the number of oocytes retrieved. Results: Cycle characteristics were similar between the study (SE decrease) and control groups, with the exception of the median SE on the day of hCG triggering (899.7 pg/mL; interquartile range [IQR], 193-2,116 pg/mL vs. 1,566.8 pg/mL; IQR, 249-2,970 pg/mL; p< 0.001). The study group, relative to the control group, had significantly fewer total oocytes (5 [IQR, 2-9] vs. 7 [IQR, 3-11]; p= 0.002) and significantly fewer metaphase II (MII) oocytes (3 [IQR, 1-6] vs. 4 [IQR, 2-8]; p= 0.001) retrieved. The study group had fewer cleavage-stage embryos than the control cycles (3 [IQR, 1-6] vs. 4 [IQR, 2-7]; p= 0.012). Compared to cycles with a ≤ 20% SE decrease, cycles with a > 20% decrease had significantly fewer total and MII oocytes retrieved. SE decrease recurred in 12% of patients. Conclusion: A spontaneous decrease in SE levels adversely affected IVF outcomes, with a linear correlation between the percentage decrease and the number of oocytes retrieved. SE decrease can repeat in later cycles.

  • 1983년 5월 1일부터 1984년 10월 31일까지 1년 6개월간 영남대학 부속병원 소아과에 입원하여 "dipstick" 뇨검사를 실시한 대상 환아 844례에서 단백뇨 4.9%, 혈뇨 2.4%, 당뇨 1.1%, 케톤뇨 9.5%로 142례에서 이상 소견이 나타났다. "Dipstik" 검사의 이상 소견 발현율은 성별, 연령별, 발열 유무와는 유의한 차이를 볼 수 없었다. 중등도 이산의 탈수 증세를 나타낸 환아들은 21.2% 에서 단백뇨를, 그리고 31.8%에서 케톤뇨를 나타내어 탈수증세가 없는 환아들의 1.8% 및 1.0% 보다 유의하게 높은 양성율을 나타냈다(p<0.05). 탈수증세의 정도와 케톤뇨의 양성도는 유의한 관계를 보였다(p<0.005). 케톤뇨 양성 환아 97례 중 93.8%가 탈수증을, 54.6%가 위장관염을, 51.5%가 발열을, 그리고 29.9%가 호흡기 질환을 동반하였다. 단백뇨와 케톤뇨가 양성이었던 경우 반복검사에서 모두 음성으로 되었다. "Dipstick" 검사에서 혈뇨를 나타낸 13례 중 반복 검사에서 9례는 음성으로 나타났으며 4례는 계속 양성으로 냐타나 확진검사에서 만성 신우신염 2례, 무증상 뇨로감염증 1례, 양성 반복성 혈뇨 1례로 새로 진단되었다. "Dipstick" 선별검사는 비용이 적게 들며 간단한 검사로 입원 당시에 예상되지 않았던 신뇨로 질환을 찾아 내는데 도움이 되는 것으로 나타났다.

  • Background: Venous thromboembolisms (VTEs) constitute a group of diseases including deep vein thrombosis (DVT) and pulmonary embolism (PE). They regarded as the second leading cause of death in cancer patients and several studies have confirmed that VTEs have a negative impact on survival and recurrent rate in both ovarian and endometrial cancer cases. The incidence of VTEs differs worldwide and depends on several risk factors including race, underlying disease, lifestyle, body weight, BMI and genetic risk factors. There is heterogeneity of DVT rates between Asian and Western countries. This study was conducted in order to evaluate the character and incidence of VTEs in gynecologic oncology patients in King Chulalongkorn Memorial Hospital over a 10 year period. Materials and Methods: A retrospective chart review was performed with VTEs defined as objective diagnosis of acute DVT or PE with typical symptoms and signs. Diagnoses were approved byan internist and/or confirmed with imaging studies. Data from both outpatient and inpatient sessions of the affected cases from January 2004 to December 2013 were extracted. General characteristics of the patients were collected with details of the diseases, types of cancer, stage, date of diagnosis of cancer, operative data, treatment outcome, progression free survival and overall survival. Results: Thirty cases of VTEs were identified in a total 2,316 gynecologic oncology cases. The incidence of symptomatic VTEs in total gynecologic oncology patients in our institution is 1.295%. The incidence of VTEs in ovarian cancer patients in our institution was 5.9%. Duration for VTE detection ranged from 13 months before diagnosis of cancer to 33 months after diagnosis of cancer. Most of the VTE cases were detected in ovarian cancer patients (60%). The most common cell type was adenocarcinoma (moderately to poorly differentiated) which accounted for 26.7% of the cases. The second most common cell type was clear cell carcinoma with 23.3% of the cases. Thirty percent of VTE cases developed before cancer was diagnosed, 20% were diagnosed at the same time as cancer detection and fifty percent developed after cancer was diagnosed. Median disease free survival of the gynecologic oncology patients with VTE was 7.5 months. Median overall survival (OS) was 12 months. Median progession free survivals of DVT and PE groups were 11.5 and 5.5 months, respectively. OS of DVT and PE was 12.0 and 11.5 months respectively. Conclusions: The incidence of VTE in Asian countries is believed to be lower than in European or Western countries. From our retrospective review, the incidence of VTEs in all types of gynecologic oncology was 1.295%, much lower than reported in the West. The reason for the lower incidence may genetic differences. Another factor is that VTE in this review was symptomatic, which is less than asymptomatic VTE. More than half of VTEs in this study developed in ovarian cancer patients. The results are compatible with earlier reports that among gynecologic malignancies, the incidence of VTE is highest in ovarian cancer.

  • Background: Soft tissue sarcomas (STS) must be managed with a team involving pathologists, radiologists, surgeons, radiation therapists and medical oncologists. Treatment modalities and demographic charasteristics of Turkish STS were analysed in the current study. Material-Methods: Primary adult STS followed between 1999-2010 in Cukurova University Medical Faculty Department of Medical Oncology were analzied retrospectively Results: Of the total of 498 patients, 238 were male and 260 female. The most seen adult sarcomas were leomyosarcoma (23%). Localization of disease was upper extremity (8.8%), lower extremity (24.7%), head-neck 8.2%, thoracic 8%, retroperitoneal 5.6%, uterine 12.4%, abdominal 10%, pelvic region 3.6 and other regions 10%. Some 13.1% were early stage, 10.2% locally advanced, 8.2% metastatic and 12.2% recurrent disease. Patients were treated with neoadjuvant/adjuvant (12%) or palliative chemotherapy (7.2%) and 11.4% patients did not receive chemotherapy. Surgery was performed as radical or conservative. The most preferred regimen was MAID combination chemotherapy in the rate of 17.6%. The most common metastatic site was lung (18.1%). The overall survival was 45 months (95%CI 30-59), 36 months in men and 55 months in women, with no statistically significant difference (p=0.5). The survival rates were not different between the group of adjuvant and palliative chemotherapy (respectively 28 versus 18 months) (p=0.06), but radical surgery at 37 months was better than 22 months for conservative surgery (p=0.0001). No differences were evident for localization (p=0.152). Locally advanced group had higher overall survival rates (72 months) than other stages (p=0.0001). Conclusion: STS can be treated successfully with surgery, chemotherapy and radiotherapy. The survival rates of Turkish people were higher in locally advanced group; these results show the importance of multimodality treatment approach and radical surgery.
