Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopic colorectal surgery (LCRS) and conventional open sur-gery (OCRS) for colorectal cancer (CRC). Methods: We searched relevant papers published between January 1990 and May 2011. We analyzed the outcomes of each type of surgery over the short- and long-term periods. Results: In the short-term period, we found no significant differences in overall periop-erative complications and anastomotic leakage between LCRS and OCRS groups. We found no significant differences in overall, distant, local and wound-site recurrence, overall mortality, 3 and 5 year disease-free survival rate, and cancer-related mortality between the 2 groups. Conclusions: LCRS has the benefits of reducing intraoperative blood loss, earlier re-sumption of oral intake, and shorter duration of hospital stay in the short-term. The long-term outcomes of LCRS seem to be similar to those of OCRS. © Ivyspring International Publisher.

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopy-assisted colectomy (LAC) and open colectomy (OC) for colon cancer. Methods: We searched MEDLINE, EMBASE, Science Citation Index, and Cochrane Con-trolled Trial Register for relevant papers published between January 1990 and October 2011 by using the search terms "laparoscopy," "laparoscopy-assisted," "surgery," "colectomy," "colon cancer," and "randomized clinical trials (RCTs)". We analyzed the outcomes of each type of surgery over short- and long-term periods. Results: We selected 12 papers reporting RCTs that compared LAC with OC for colon cancer. Our meta-analysis included 4614 patients with colon cancer; of these, 2444 had undergone LAC and 2170 had undergone OC. In the short-term period, we found that the rates of overall postoperative complications and ileus in LAC were lower than in OC groups. LAC was associated with a reduction in intraoperative blood loss, a shorter duration of time to resumption and hospital stay, and lower rates of overall complication and ileus over the short-term, but with similar long-term oncologic outcomes such as overall and cancer-related mortality, overall recurrence, local recurrence, distant metastasis, and wound-site recur-rence, compared to OC. Conclusions: It is suggested that LAC may be preferred to OC for colon cancer. © Ivyspring International Publisher.

Background: Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer is a minimally invasive technique. We performed a meta-analysis of five randomized clinical trials (RCTs) to evaluate and compare the benefits of LADG with those of open distal gastrectomy (ODG). Methods: The present meta-analysis was based on the comparison of LADG with ODG for gastric cancer. The following factors were examined: operative time, estimated blood loss, number of harvested lymph nodes, time to resumption of oral intake, duration of hospital stay, frequency of analgesic administration, complications, tumor recurrence, and mortality. Results: We selected five RCTs to compare LADG with ODG for gastric cancer. A total of 326 patients with gastric cancer were included in this meta-analysis of whom 164 underwent LADG and 162 underwent ODG. There was a significant difference in the volume of intraoperative blood loss, period of hospital stay, frequency of analgesic administration, and rate of complications between LADG and ODG. There was no difference in the resumption of oral intake, rate of tumor recurrence, and mortality. The operative time was significantly longer and the number of harvested lymph nodes was significantly smaller in LADG than in ODG. Conclusion: LADG is significantly superior to ODG regarding the volume of blood loss, duration of hospital stay, level of pain, and risk of complications. There was no difference in the resumption of oral intake, rate of tumor recurrence, and mortality. However, LADG was significantly inferior to ODG regarding operative time and also had a smaller number of harvested lymph nodes. © 2011 Elsevier Inc. All rights reserved.

Background: We conducted a meta-analysis to evaluate and compare the advantages of laparoscopy-assisted distal gastrectomy (LADG) over open distal gastrectomy (ODG) for treating early gastric cancer (EGC). Methods: We searched MEDLINE, EMBASE, Science Citation Index, and Cochrane Controlled Trial Register for relevant papers published between January 1990 and January 2010 by using the following search terms: laparoscopy-assisted gastrectomy, laparoscopic gastrectomy, and early gastric cancer. The following data were analyzed: operative time, estimated blood loss, number of harvested lymph nodes, time required for resumption of oral intake, duration of hospital stay, frequency of analgesic administration, complications, tumor recurrence, and mortality. Results: We selected four papers reporting randomized control studies (RCTs) that compared LADG with ODG for EGC. Our meta-analysis included 267 patients with EGC; of these, 134 and 133 had undergone LADG and ODG, respectively. The volume of intraoperative blood loss, frequency of analgesic administration, and rate of complications were significantly lesser for LADG than for ODG. However, the time required for resumption of oral intake and duration of hospital stay did not significantly differ between LADG and ODG. The operative time for LADG was significantly longer than that for ODG; further, the number of harvested lymph nodes was significantly lesser in the LADG group than in the ODG group. Conclusion: LADG is advantageous over ODG because it results in lesser blood loss, is less painful, and is associated with a low risk of complications. Additional RCTs that compare LADG and ODG and investigate the long-term oncological outcomes of LADG are required to determine the advantages of LADG over ODG. © 2010 The Society for Surgery of the Alimentary Tract.

Purpose: We conducted a meta-analysis to evaluate and compare the outcomes of laparoscopic and open surgery for the treatment of patients with acute appendicitis. Methods: We searched MEDLINE, EMBASE, Science Citation Index, and the Cochrane Controlled Trial Register for relevant papers published between January 1990 and February 2012. We analyzed 22 outcomes of laparoscopic and open surgery for acute appendicitis. Results: We identified 39 papers reporting results from randomized controlled trials that compared laparoscopic surgery with open surgery for acute appendicitis. Our meta-analysis included 5,896 patients with acute appendicitis; 2,847 had undergone laparoscopic surgery, and 3,049 had undergone open surgery. Compared with open surgery, laparoscopic surgery was associated with longer operative time (by 13.12 min). However, compared with open surgery, laparoscopic surgery for acute appendicitis was associated with earlier resumption of liquid and solid intake; shorter duration of postoperative hospital stay; a reduction in dose numbers of parenteral and oral analgesics; earlier return to normal activity, work, and normal life; decreased occurrence of wound infection; a better cosmesis; and similar hospital charges. Conclusions: Laparoscopic surgery may now be the standard treatment for acute appendicitis. © 2012 The Society for Surgery of the Alimentary Tract.

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopy-assisted and open rectal surgery for the treatment of patients with rectal cancer. Methods: We searched MEDLINE, EMBASE, Science Citation Index, and the Cochrane Controlled Trial Register for relevant papers published between January 1990 and April 2011 by using the search terms "laparoscopy," "laparoscopy assisted," "surgery," "rectal cancer," and "randomized controlled trials." We analyzed outcomes over short- and long-term periods. Results: We identified 12 papers reporting results from randomized controlled trials that compared laparoscopic surgery with open surgery for rectal cancer. Our meta-analysis included 2,095 patients with rectal cancer; 1,096 had undergone laparoscopic surgery, and 999 had undergone open surgery. In the short-term period, 13 outcome variables were examined. In the long-term period, eight oncologic variables, as well as late morbidity, urinary function, and sexual function were analyzed. Laparoscopic surgery for rectal cancer was associated with a reduction in intraoperative blood loss and the number of transfused patients, earlier resumption of oral intake, and a shorter duration of hospital stay over the short-term, but with similar short-term and long-term oncologic outcomes compared to conventional open surgery. Conclusions: Laparoscopic surgery may be an acceptable alternative treatment option to conventional open surgery for rectal cancer. © 2011 The Society for Surgery of the Alimentary Tract.

Human rhinovirus (HRV) is a causative agent of acute respiratory tract infection (ARTI). In 2007, a novel HRV group, HRV-C, was discovered. This study, which assessed whether HRV-C is epidemic among patients with ARTI, was aimed at analyzing the seasonal prevalence of HRV-C in Osaka City, Japan. Gene amplification tests were performed to detect 10 respiratory viruses in 336 specimens collected during November 2008-October 2009. In total, 364 viruses were detected in 271 specimens. The most commonly detected virus was HRV (n=84). For HRV-positive specimens, we conducted phylogenetic analyses using the VP4/VP2 gene region to identify the HRV species (HRV-C, 30; HRV-A, 54). Both the number and rate of HRV-C detection were highest in December. The highest numbers and the highest rate of HRV-A detection were obtained in April and June and in April, respectively. Statistical analysis showed that the most probable prevalent period of HRV-C was between September and March, and that of HRV-A was between March and November. These results suggest that HRV-C is mainly epidemic during autumn and early spring; this seasonal prevalence was different from that of HRV-A. Moreover, the HRV-C Osaka strains were scattered in many genetic clusters along with previously reported strains from different parts of the world. This result also emphasizes the worldwide circulation of HRV-C.

A 23-year-old woman was admitted with complaints of swelling and pain in the left breast, fever, polyarthralgia and erythema nodosum. A fine-needle biopsy of the mass in the left breast revealed non-caseous granulomatous lobulitis. A diagnosis of granulomatous mastitis was thus made. The administration of prednisolone 40 mg/day resulted in the resolution of the patient's symptoms, and the breast mass thereafter decreased in size. The mass relapsed during the subsequent prednisolone taper. Additional therapy with methotrexate resulted in complete remission. Granulomatous mastitis should therefore be included in the differential diagnosis of polyarthralgia. © 2012 The Japanese Society of Internal Medicine.

Human norovirus (NoV) is an important cause of the epidemic acute gastroenteritis in children and adults. This review mentions on the required knowledge to understand morphology, genetics, transmission, pathogenesis, and control. The development of molecular diagnostic techniques is clarified the epidemiological impact that is now recognized not only as the major cause of foodborne gastroenteritis outbreaks but also as a cause of sporadic gastroenteritis. It was recognized that the combination pattern to an intestinal epithelium of NoV was prescribed in organization, blood type antigen (histoblood group antigen: HBGA). In children, NoV has various complications especially benign convulsions associated with mild gastroenteritis and associated-encephalopathy. NoV virus-like particle (VLP) vaccine is developing as the protection against acute viral gastroenteritis with a homologous virus.
