| 1 | Invasive group B streptococcal infection in a patient with post splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension显示文摘BACKGROUND:Splenectomy in patients with liver cirrhosis(LC)is expected to become more common owing to its efficacy on portal hemodynamics.In this report we describe an alarming case of group B streptococcus(GBS)infection after splenectomy in a patient with LC.METHODS:A 72-year-old woman with a history of LC was admitted to our emergency department because of respiratory failure.The patient had received left lateral segmentectomy of the liver and splenectomy three months before admission.Pulmonary examination revealed significant wheezing during inspiration and expiration,but no crackles and stridor.Chest radiography and CT showed no infiltrates.A presumptive diagnosis of bronchial asthma caused by upper respiratory infection was made.Four days after admission,GBS infection was confirmed by blood culture and penicillin G was administered.Antibiotics were given intravenously for a total of 12 days.RESULTS:The patient was discharged on the 12th day after admission.CONCLUSIONS:Although efficacy of splenectomy in patients with LC has been reported,immune status should be evaluated for a longer period.Patients who have undergone splenectomy are highly susceptible to bacteria;moreover,LC itself is an independent risk factor for mortality in patients with sepsis.Since prophylaxis against GBS has not been established,immediate action should be taken.Emergency physicians should be aware of invasive GBS infection in the context of the critical risk factors related to splenectomy and LC,particularly the expected increase of splenectomy performed in LC patients. | Tomoya Okazaki Toru Hifumi Arisa Manabe Hikari Matsumura Satoshi Egawa Hideyuki Hamaya Nastuyo Shinohara Koshiro Takano Hajime Shishido Yuko Abe Kenya Kawakita Masanobu Hagiike Yasuhiro Kuroda | 2016 | World Journal of Emergency Medicine2016，7，1： | 6 |
| 2 | 在有阴暗胃肠的流血的病人的囊内视镜检查法的计算图象修正的功效显示文摘 AIM:To investigate whether flexible spectral color enhancement(FICE) improves diagnostic yields of capsule endoscopy(CE) for obscure gastro-intestinal bleeding(OGIB).METHODS:The study subjects consisted of 81 patients.Using FICE,there were three different sets with different wavelengths.Using randomly selected sets of FICE,images of CE were evaluated again by two individuals who were not shown the conventional CE reports and findings.The difference between FICE and conventional imaging was examined.RESULTS:The overall diagnostic yields in FICE sets 1,2,3 and conventional imaging(48.1%) were 51.9%,40.7%,51.9% and 48.1%,respectively,which showed no statistical difference compared to conventional imaging.The total numbers of detected lesions per examination in FICE imaging and conventional imaging were 2.5 ± 2.1 and 1.8 ± 1.7,respectively,which showed a significant difference(P = 0.01).CONCLUSION:The diagnostic yield for OGIB is not improved by FICE.However,FICE can detect significantly more small bowel lesions compared to conventional imaging. | Tomoaki Matsumura Makoto Arai Toru Sato Tomoo Nakagawa Daisuke Maruoka Masaru Tsuboi Sachio Hata Eiji Arai Tatsuro Katsuno Fumio Imazeki Osamu Yokosuka | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，9： | 4 |
| 3 | Ectopic hepatocellular carcinoma mimicking a retroperitoneal tumor:A case report显示文摘BACKGROUND An ectopic hepatocellular carcinoma(EHCC)arises from the ectopic liver which is defined as a hepatic organ or tissue not connected to surrounding tissues.EHCC is a rare disease and it is difficult to diagnose preoperatively.Furthermore,the clinical features are not fully elucidated.CASE SUMMARY A retroperitoneal tumor(6 cm)was located at the dorsal side of the pancreas head on abdominal ultrasonography in an 81-year old woman positive for hepatitis C virus antibody.Contrast enhanced-computed tomography and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging showed viable HCC patterns with early enhancement and delayed washout.The tumor markers-serum alphafetoprotein and alpha-fetoprotein-L3%-were increased to 30.1 ng/m L and83.1%,respectively.Protein induced by vitamin K absence or antagonist-Ⅱwas within normal levels(17 m AU/m L).Positron emission tomography-computed tomography showed strong accumulation into the tumor(Standardized Uptake Value max:13.8),and the tumor cytology following endoscopic ultrasoundguided fine needle aspiration showed poorly differentiated carcinoma.Tumor extirpation was performed,and operative findings showed that the retroperitoneal tumor was disconnected from the pancreas and the liver.Swollen lymph nodes near the tumor were histologically normal.On histological examination,the tumor was finally diagnosed as EHCC with Arginase-1 positive expression.CONCLUSION We report our experience of a rare EHCC which was difficult to diagnose,and we present a review of the literature. | Yuki Adachi Hiromitsu Hayashi Toshihiko Yusa Toru Takematsu Kazuki Matsumura Takaaki Higashi Kensuke Yamamura Takanobu Yamao Katsunori Imai Yo-ichi Yamashita Hideo Baba | 2020 | World Journal of Gastroenterology2020，26，18： | 3 |
