Risk factors for incisional surgical site infections in elective surgery for colorectal cancer: focus on intraoperative meticulous wound management

Purpose

An incisional surgical site infection (I-SSI) is a frequently observed complication following colorectal surgery. Intraoperative wound management is one of the most important factors that determine the incidence of postoperative I-SSI. The purpose of this study was to assess the impact of the methods used for intraoperative wound management on the incidence of I-SSI following elective surgery for colorectal cancer.

Methods

Between November 2009 and February 2011, the data of 1,980 consecutive patients who underwent elective colorectal resection for colorectal cancer were prospectively collected from 19 affiliated hospitals. The incidence of and risk factors for I-SSI were investigated.

Results

Overall, 233 I-SSIs were identified (11.7 %). Forty-two possible risk factors were analyzed. Using a multivariate analysis, the independent risk factors for I-SSI were identified to be a high body mass index, previous laparotomy, chronic liver disease, wound length, contaminated wound class, creation or closure of an ostomy, right hemicolectomy procedure, the suture material used for fascial closure and the incidence of organ/space SSI.

Conclusion

To prevent I-SSI following elective colorectal surgery, it is crucial to avoid making large incisions and reduce fecal contamination whenever possible. A high quality randomized control trial is necessary to confirm the definitive intraoperative procedure(s) that can minimize the incidence of I-SSI.     

The relationship between initial clinical manifestation and long-term prognosis of patients with systemic lupus erythematosus

The relationship between clinical manifestations and prognosis was examined and evaluated among systemic lupus erythematosus (SLE) patients. A total of 542 patients with SLE were selected and divided into nine groups according to their main clinical manifestation at the time of initial diagnosis. The relationship between these clinical manifestations and long-term prognosis was evaluated in respect to the survival, remission, relapse rates, the development of a new clinical manifestation, and/or damage index. Patients with neuropsychiatric SLE (NPSLE), accompanied with acute confusional state/seizure disorder, cerebral vascular disease, or pneumonitis had poor survival rates with cause of death related to their major organ involvement. Patients with nephropathy or leukopenia had lower remission rates, and an increase in relapse rates was frequently recognized in patients with pneumonitis. Body damage (damage index) was higher in patients with lupus psychosis, pneumonitis, and/or arthritis. The translation of the main manifestations after diagnosis was confirmed in 64 patients (11.8%), and often observed in patients with autoimmune hemolytic anemia and arthritis. The majority of these manifestations were nephropathy, NPSLE, thrombocytopenia, and pneumonitis, and the prognosis of patients with nephropathy and thrombocytopenia as a new main manifestation had a poor outcome. The results of long-term prognosis in SLE greatly differed with respect to the initial clinical manifestation at the time of diagnosis.     

Central pontine myelinolysis after living donor liver transplantation

There are few reports of central pontine myelinolysis after living donor liver transplantation. A 59-year-old male received a right liver graft from his daughter for hepatitis B-related liver cirrhosis. Methylprednisolone and tracrolimus were used for immunosuppression. Dysarthria and dysphasia were noted on the second postoperative day. Brain magnetic resonance image taken on the 9th postoperative day revealed a hyperintense area at the center of his pons in T2-weighted images. The symptoms improved spontaneously 1 month after the operation. Central pontine myelinolysis should be included in the differential diagnosis when neurologic manifestations are observed after living donor liver transplantation.     

Do Cancer Patients Tweet? Examining the Twitter Use of Cancer Patients in Japan

Background

Twitter is an interactive, real-time media that could prove useful in health care. Tweets from cancer patients could offer insight into the needs of cancer patients.

Objective

The objective of this study was to understand cancer patients’ social media usage and gain insight into patient needs.

Methods

A search was conducted of every publicly available user profile on Twitter in Japan for references to the following: breast cancer, leukemia, colon cancer, rectal cancer, colorectal cancer, uterine cancer, cervical cancer, stomach cancer, lung cancer, and ovarian cancer. We then used an application programming interface and a data mining method to conduct a detailed analysis of the tweets from cancer patients.

Results

Twitter user profiles included references to breast cancer (n=313), leukemia (n=158), uterine or cervical cancer (n=134), lung cancer (n=87), colon cancer (n=64), and stomach cancer (n=44). A co-occurrence network is seen for all of these cancers, and each cancer has a unique network conformation. Keywords included words about diagnosis, symptoms, and treatments for almost all cancers. Words related to social activities were extracted for breast cancer. Words related to vaccination and support from public insurance were extracted for uterine or cervical cancer.

Conclusions

This study demonstrates that cancer patients share information about their underlying disease, including diagnosis, symptoms, and treatments, via Twitter. This information could prove useful to health care providers.     

Spondylocostal dysostosis with tetralogy of Fallot and herniation of the spleen through the diaphragm

Spondylocostal dysostosis (SCD) is a very rare syndrome characterized by vertebral malformation and rib deformity. Some of the patients with SCD have other birth defects in the central nervous system, the genitourinary tract, diaphragm or heart and so forth. There have been reported SCD with complex congenital heart disease, such as pulmonary atresia, double outlet right ventricle, and d‐transposition of great arteries. However, there have been no reported SCD patients with confirmed tetralogy of Fallot (TOF). Here, a patient with SCD having a very rare combination of rib defects on the right side and left‐sided scoliosis, tetralogy of Fallot, and diaphragmatic spleen herniation, which had not been reported before, was described.     

Tannin-phytobezoars with Gastric Outlet Obstruction Treated by Dissolution with Administration and Endoscopic Injection of Coca-ColaⓇ, Endoscopic Crushing,and Removal (with Video)

A 77-year-old man complained of postmeal vomiting and sustained general fatigue. An abdominal computed tomography scan showed massive gastric expansion and fluid storage. Gastroscopy revealed four gastric bezoars that were considered to have caused pyloric ring obstruction. The patient was asked to drink 500 mL per day of Coca-Cola^Ⓡ for 4 days. On the fourth day, we performed endoscopic crushing and removal by injecting Coca-Cola^Ⓡ, cutting the softened bezoar with endoscopic snares, and collecting the pieces with endoscopic nets. We herein report (with a video presentation) a rare case of tannin-phytobezoars endoscopically removed with the administration and injection of Coca-Cola^Ⓡ.
