Mutations in carboxy-terminal part of E2 including PKR/eIF2αphosphorylation homology domain and interferon sensitivity determining region of nonstructural 5A of hepatitis C virus 1b:Their correlation with response to interferon monotherapy and viral load

World Journal of Gastroenterology 2006年第23期12卷 3722-3728页

AIM： To study the amino acid substitutions in the carboxy （C）-terminal part of E2 protein and in the interferon （IFN） sensitivity determining region （ISDR） and their correlation with response to IFN and viral load in 85 hepatitis C virus （HCV）-lb-infected patients treated with IFN. METHODS： The C-terminal part of E2 （codons 617-711） including PKR/eIF2α phosphorylation homology domain （PePHD） and ISDR was sequenced in 85 HCV-1b-infected patients treated by IFN monotherapy. RESULTS： The amino acid substitutions in PePHD detected only in 4 of 85 patients were not correlated either with response to iFN or with viral load. The presence of substitutions in a N-terminal variable region （codons 617-641） in the C-terminal part of E2 was significantly correlated with both small viral load （33.9% vs 13.8%, P = 0.0394） and sustained response to iFN （25.0% vs 6.9 %, P = 0.0429）. Four or more substitutions in ISDR were significantly correlated with both small viral load （78.6% vs 16.2%, P 〈 0.0001） and sustained response to iFN （85.7% vs 2.9%, P 〈 0.0001）. In multivariate analysis, ISDR in nonstructural （NS） 5A （OR = 0.39, P 〈 0.0001） and N-terminal variable region （OR = 0.51, P = 0.039） was selected as the independentpredictors for small viral load, and ISDR （OR = 39.0, P 〈 0.0001） was selected as the only independent predictor for sustained response. CONCLUSION： The N-terminal variable region in the C-terminal part of E2 correlates with both response to IFN monotherapy and viral load and is one of the factors independently associated with a small viral load.

Clinical outcomes of enteroscopy using the double-balloon method for strictures of the small intestine

AIM:To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine. METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, 3apan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel.

Non-steroidal anti-inflammatory drug-induced small bowel injuries identified by double-balloon endoscopy

引用

World Journal of Gastroenterology 2005年第31期11卷 4861-4864页

AIM： To clarify clinical features of the NSAID-induced sma bowel lesions using a new method of endoscopy. METHODS： This is a retrospective study and we analyzed seven patients with small bowel lesions while taking NSAIDs among 61 patients who had undergone doubleballoon endoscopy because of gastro-intestinal bleeding or anemia between September 2000 and March 2004, at .lichi Medical School Hospital in Japan. Neither conventional EGD nor colonoscopy revealed any lesions of potential bleeding sources including ulcerations. Double-balloon endoscopy was carried out from oral approach in three patients, from anal approach in three patients, and from both approaches in one patient. RESULTS： Ulcers or erosions were observed in the ileum in six patients and in the jejunum in one patient, respectively. The ulcers were multiple in all the patients with different features from tiny punched out ulcers to deep ulcerations with oozing hemorrhage or scar. All the patients recovered uneventfully and had full resolution of symptoms after suspension of the drug. CONCLUSION： NSAIDs can induce injuries in the small bowel even in patients without any lesions in both the stomach and colon.

Efficacy of subcutaneous penrose drains for surgical site infections in colorectal surgery

引用

World Journal of Gastrointestinal Surgery 2013年第4期5卷 110-114页

作者： Shinya Imada Shingo Noura Masayuki Ohue Tatsushi Shingai Toshinori Sueda kentaro Kishi Terumasa Yamada Hiroaki Ohigashi Masahiko yano Osamu Ishikawa Department of Surgery Osaka Medical Center for Cancer and Cardiovascular Diseases

AIM: To investigate whether a subcutaneous penrose drain would decrease the superficial surgical site infection (s-SSI) rate in elective colorectal surgery. METHODS: This is a comparative study of the historical control type. Intervention consisted of the use of penrose drain in elective open colorectal surgical wounds. The outcome was an incidence of s-SSI. The patients were risk stratified according to the depth of subcutaneous ***: There were 131 patients (40 patients with high s-SSI risk) in the prior period (from July 2008 to June 2009, when no penrose drains were inserted) and 151 patients (75 patients with high s-SSI risk) in the latter period (from June 2010 to November 2011, when penrose drains were inserted). The overall s-SSI rate was 6.1% and 5.3% during the two periods (P = 0.770), and the s-SSI rate in the high s-SSI risk group was 15.0% and 8.0% (P = 0.242).CONCLUSION: Although penrose drain was not observed to significantly reduce s-SSI, there tended to be a reduced risk of s-SSI in the high s-SSI risk group.

Solitary mediastinal lymph node recurrence after curative resection of colon cancer

引用

World Journal of Gastrointestinal Surgery 2014年第8期6卷 164-168页

作者： Yasuhiro Matsuda Masahiko yano Norikatsu Miyoshi Shingo Noura Masayuki Ohue Keijiro Sugimura Masaaki Motoori kentaro Kishi Yoshiyuki Fujiwara Kunihito Gotoh Shigeru Marubashi Hirofumi Akita Hidenori Takahashi Masato Sakon Department of Surgery Osaka Medical Center for Cancer and Cardiovascular Disease

We report two cases of solitary mediastinal lymph node recurrence after colon cancer resection. Both cases had para-aortic lymph node metastasis at the time of initial surgery and received adjuvant chemotherapy for 4 years in case 1 and 18 mo in case 2. The time to recurrence was more than 8 years in both cases. After resection of the recurrent tumor, the patient is doing well with no recurrence for 6 years in case 1 and 4 mo in case 2. Patients should be followed up after colon cancer surgery considering the possibility of solitary mediastinal lymph node recurrence if they had para-aortic node metastasis at the time of initial surgery.
