A single-center retrospective analysis of the efficacy and safety of a modified regimen of irinotecan plus S-1 (IRIS) with molecular targeting agents as second-line chemotherapy in Japanese patients with recurrent or nonresectable colorectal cancer.

Background: As the second-line chemotherapy for stage IV recurrent or nonresectable colorectal cancer, our hospital started a modified treatment regimen comprising of irinotecan plus S-1 (IRIS) [tegafur/gimeracil/oteracil (S-1)] plus molecular targeting agents (MTAs), i.e., an epidermal growth factor receptor (EGFR) inhibitor such as panitumumab (P-mab) or cetuximab (C-mab) or vascular endothelial growth factor (VEGF) inhibitor such as bevacizumab (B-mab) since October 2012.

Efficacy of hand-assisted laparoscopic surgery (HALS) in older adult patients (≥80 years) with primary colorectal cancer.

Background: From 2004 to 2014, 821 colorectal cancer primary resections were conducted at our institution. Of these, 102 patients (12.4%) were older adults over 80 years old.

Severe Sacral Region Pressure Ulcer Infection Treated in Negative Pressure Wound Therapy with Instillation and Dwelling: A Case Report.

We report a case of severe sacral osteomyelitis and sepsis with pressure ulcer infection treated with negative pressure wound therapy with instillation and dwelling (NPWTi-d) V.A.C.

Characteristic of the acute drug intoxication conveyed by Kanagawa helicopter emergency medical service.

Aim: Various critical cases have been transported since the use of the Kanagawa Helicopter Emergency Medical Service (HEMS) started at Tokai University Hospital (Isehara, Japan) in 2002, including cases of acute poisoning. We analyzed the characteristics of acute poisoning cases conveyed by the HEMS.

Methods: Kanagawa HEMS conveyed 3,814 cases from July 2002 to March 2013, and acute drug and poison intoxication was diagnosed in 131 of these cases.

Comparison of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy in patients with colorectal cancer: Final results from a single center.

In recent years, the use of laparoscopic surgery has been expanded to include radical curative resection. In a previous study, 212 patients with primary colorectal cancer (stages I-III) underwent radical curative resection by hand-assisted laparoscopic surgery (HALS) (n=98) or conventional laparotomy (CL) (n=114) and were compared with respect to 3-year relapse-free survival (3Y-RFS) and 3-year overall survival (3Y-OS). The study included 210/212 patients who were followed up to 5 years, including 96 patients who underwent HALS and 114 treated with CL.

A Prospective, Single-Arm, Single-Center, Case Series to Determine the Feasibility of Safe Skill Transfer for Transabdominal Preperitoneal (TAPP) Repair Utilizing a Hands-On Mentorship Model.

Objectives: It is difficult to introduce laparoscopic surgery in institutions with a small number of patients, and surgical training relies heavily on mentors to produce well-trained surgeons. The aim of this study was to determine whether implementation of a hands-on mentorship model could provide safe skill transfer for transabdominal preperitoneal (TAPP) repair.

Methods: A trainee who had no experience with TAPP repair underwent operative tutorials until the mentor judged that the trainee could carry out the operation independently.

The first case of huge amebic intra-abdominal tumor with asymptomatic amebic colitis.

We report a rare case of huge amebic intra-abdominal tumor with asymptomatic amebic colitis. This appears to represent the first report of amebic intra-abdominal tumor. A 31-year-old woman presented to a local doctor with only a sensation of abdominal fullness.

Comparison of hand-assisted laparoscopic surgery and conventional laparotomy for rectal cancer: Interim results from a single center.

Minimally invasive laparoscopic surgery has become widespread and the indications for such surgery have recently been extended to various conditions, including rectal cancer. The objective of this study was to compare the clinical outcome of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) in patients with rectal cancer. Patients who underwent radical resection of stage I-III primary rectal cancer (n=111) were classified into those receiving HALS (n=57) and those receiving CL (n=54); the two groups were matched for stage and postoperative treatment.

Comparison of hand-assisted laparoscopic surgery and conventional laparotomy for colorectal cancer: Interim results from a single institution.

The present study aimed to compare the results of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) at a single institution in Japan. Of the 212 patients with stage I/II/III colorectal cancer who received a curative resection, 98 patients underwent HALS and 114 patients underwent CL. The clinical background and post-operative management did not differ between the two groups.

Characteristics of elderly Japanese patients with severe burns.

In this study, we report the clinical characteristics of elderly Japanese patients with severe burns. We studied the clinical features of 76 adult patients with severe burns, 35 of whom (46.1%) were ≥65 years old.

A 92-year-old man with retropharyngeal hematoma caused by an injury of the anterior longitudinal ligament.

Traumatic retropharyngeal hematoma is a rare condition and may be lethal in some cases. In patients with this condition, the absence of a vertebral fracture or a major vascular injury is extremely rare. We present the case of a 92-year-old man who hit his forehead by slipping on the floor in his house.

Arterial embolization in patients with grade-4 blunt renal trauma: evaluation of the glomerular filtration rates by dynamic scintigraphy with 99mTechnetium-diethylene triamine pentacetic acid.

Background: High-grade blunt renal trauma has been treated by arterial embolization (AE). However, it is unknown whether AE preserves renal function, because conventional renal function tests reflect total renal function and not the function of the injured kidney alone. Dynamic scintigraphy can assess differential renal function.

Comparative study of nifekalant versus amiodarone for shock-resistant ventricular fibrillation in out-of-hospital cardiopulmonary arrest patients.

Background: In Japan, intravenous nifekalant (NIF) was often used for direct current cardioversion-resistant ventricular fibrillation (VF), until the use of intravenous amiodarone (AMD) was approved in 2007. The defibrillatory efficacy of NIF and AMD has thus far not been compared for resuscitation.

Methods And Results: Between August 2007 and April 2009, 403 consecutive out-of-hospital patients with cardiopulmonary arrest were transferred to the Emergency Medical Service of Tokai University.
