In the medical interview portion of the objective structured clinical examination (OSCE), we usually use both detailed checklists and a global rating scale to evaluate a student's performance. In the present study we investigated a problem with the detailed checklists.
1) The quality of the assessment of information-gathering capability was investigated in a station for the medical interview in a pharmaceutical OSCE.
2)A video review revealed a 7% error in the detailed checklist assessment at the OSCE station.
3) Following the interview in this study, the students wrote down the information they had gathered. These results differed by 15.6% from those of the detailed checklist assessment at the OSCE station.
4) In the present style of OSCE, the detailed checklist assessment at the OSCE station is problematic. The style in which the students write down the gathered information after the interview might be re-considered.

Auto-transplantation of adipose tissue is commonly used for the treatment of tissue defects in plastic surgery. The survival of the transplanted adipose tissue is not always constant, and one of reasons is the accelerated apoptosis of the implanted preadipocytes. We have recently established highly homogeneous preadipocytes, named ccdPAs. The aim of the current study was to evaluate the regulation of the potency of platelet-rich plasma (PRP) on the apoptosis of ccdPAs in vitro. PRP stimulated the proliferation of the preadipocytes in a dose-dependent manner, and the stimulatory activity of 2% PRP was significantly higher than that of 2% FBS or 2% platelet-poor plasma (PPP). The presence of 2% PRP significantly inhibited serum starvation- or TNF-alpha/cycloheximide-induced apoptosis in comparison to 2% FBS or 2% PPP. DAPK1 and Bcl-2-interacting mediator of cell death (BIM) mRNAs were reduced in the preadipocytes cultured with 2% PRP in comparison to those cultured in 2% FBS. The gene expression levels were significantly higher in cells cultured without serum in comparison to cells cultured with 2% FBS, and the levels in the cells with 2% PRP were reduced to 5-10% of those in the cells without serum. These results indicated that ccdPAs exhibit anti-apoptotic activities, in addition to increased proliferation, when cultured in 2% PRP in comparison to the same concentration of FBS, and that this was accompanied with reduced levels of DAPK1 and BIM mRNA expression in in vitro culture. PRP may improve the outcome of transplantation of adipose tissue by enhancing the anti-apoptotic activities of the implanted preadipocytes.

The present experiment aims to examine the efficiency of estrus synchronization using progesterone and equine chorionic gonadotrophin (eCG) and to look at luteal function. During the non-breeding and breeding season, 5 adult female Korean native goats were injected intramuscularly with 2.5 ml of physiological saline as the control. A progesterone impregnated intravaginal sponge was then kept in the same goats for 10 days followed, after a week, by an intramuscular injection of 500 IU eCG. Five adult female Nubian goats were mated with a fertile buck during the non-breeding season. During the non-breeding season 2 of the 5 goats showed a normal estrous cycle (ranging from 18 to 21 days) and 3 a short estrous cycle (ranging from 3 to 6 days). During the breeding season the equivalent figures were 1 and 2. The major axes of the corpus luteum (CL) were measured by means of calipers built into the ultrasonography system, and the concentrations of plasma progesterone (P(4)) were determined by double antibody radioimmunoassay. The mean major axes of the CL in goats showing the short cycle (6.1 +/- 0.5 mm) was significantly smaller than in those showing the normal cycle (8.9 +/- 0.5 mm; p < 0.01) and also the value of P4 in goats showing the short cycle (4.2 +/- 2.1 ng/ml) was significantly lower than for those showing the normal cycle (10.3 +/- 4.3 ng/ml; p < 0.05) at day 3 following ovulation. Three out of 5 Nubian goats became pregnant but only one goat carried to full term. The present experiment indicated that a combination of progesterone and eCG was effective in inducing estrus, although it resulted in a high incidence of short luteal lifespan. The low kidding rate and high incidence of embryonic loss may be due to the instability of the luteal lifespan.

In our hospital, we typically perform laparoscopic partial gastrectomy as surgical treatment for extragastric growth type of submucosal tumor (SMT), and laparoscopic intragastric surgery for intragastric growth type. In 2008, laparoscopic and endoscopic cooperative surgery (LECS) was reported for the first time by Hiki et al. Against the background of LECS as laparoscopic local gastric resection with endoscopic resection, we started LECS for gastric SMT from 2015. We performed laparoscopic (LAP) surgery for 15 gastric SMT cases from 2009, and compared 5 cases for which LECS was performed and 10 cases for which LAP was performed. Tumor diameter was 15–21 mm (mean 19.2 mm) in the LECS group, and 20–53 mm (mean 35.5 mm) in the LAP group; the LECS group had a significantly smaller tumor diameter. Operative time was 299 ± 45 min in LECS and 222 ± 25 min in LAP. The volume of blood loss was 24 ± 13 mL in LECS and 33 ± 13 mL in LAP. Hospitalization days was 14.0 ± 3.0 days in LECS and 12.9 ±0.8 days in LAP. There was no significant difference between them.

A 17-year-old male was admitted to our hospital because of strong abdominal pain. His symptoms gradually worsened even after hospitalization, and contrast computed tomography (CT) revealed hemorrhage in the abdominal cavity. Interventional radiology (IVR) was performed to identify the bleeding site. No obvious source of bleeding was identifiable on IVR, so we opted to perform laparoscopic examination and hemostasis. The intraperitoneal finding was hematoma in the omentum, and omentectomy was performed for idiopathic omental hemorrhage because there was no history of trauma. The postoperative course was good and the patient was discharged after postoperative day 4. Performing laparoscopic surgery for omental hemorrhage facilitated minimally invasive treatment with a short hospital stay.

Simultaneous creation of an enterostomy for enteral nutrition during esophagectomy has been useful in our experience, but bowel obstruction associated with intestinal fistula remains a problem. Therefore, in this study, we retrospectively reviewed 18 patients with esophageal cancer who underwent transdiaphragmatic transgastric tube enteral feeding catheter placement during gastric tube reconstruction via the mediastinal route after esophagectomy from November 2012 to March 2014. The catheter was guided from the gastric tube into the gastrointestinal tract, with the tip placed in the jejunum distal to the ligament of Treitz. From the gastric tube, the catheter was guided along the diaphragm to the anterior abdominal wall through the extraperitoneal route. No bowel obstruction associated with catheter placement has been observed in any of the patients from the time of surgery to this writing. Also, the procedure enabled jejunostomy use for more than 5 years, similar to conventional jejunostomy. We experienced 1 case of catheter deviation into the mediastinum. Overall, transgastric tube enteral feeding catheter placement for reconstruction of the posterior mediastinal gastric tube was useful for avoiding intestinal obstruction associated with jejunostomy. However, there may be a risk of catheter displacement into the mediastinum.

We report here 2 cases of traumatic diaphragmatic hernia. Case 1 was a 76-year-old man who was injured in a road traffic accident (RTA). Chest X-ray and computed tomography (CT) revealed prolapse of the stomach into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 12-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Case 2 was a 75-year-old man who was also injured in an RTA. Chest X-ray and CT revealed prolapse of the stomach and transverse colon into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 15-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Traumatic diaphragmatic hernia is a relatively rare condition and one that requires surgical repair. It is important to make prompt diagnosis with appropriate radiological investigations. Additionally, patients with diaphragm hernia caused by blunt trauma often have injuries to other organs. Care should be taken so as not to miss associated injuries.

A 70-year-old man with continuous diarrhea for over 1 month consulted a primary care doctor. He was treated with oral antibiotics and probiotics but his condition worsened. He developed generalized edema and was referred to our hospital. Abdominal ultrasound and computed tomography (CT) scan findings were suggestive of colon cancer with accompanying liver metastasis. Total colonoscopy and endoscopy for pathological diagnosis led to a diagnosis of cancer of the sigmoid colon accompanied with liver metastasis or liver abscess. We planned to perform sigmoidectomy with simultaneous resection of the liver lesion. However, we considered that he was not particularly fit to undergo two concurrent surgeries. Therefore, based on his physical condition, we planned to first do a sigmoidectomy. Before surgery, the fever persisted and a repeat CT scan showed deterioration of the liver lesion. We diagnosed the liver lesion as abscess and performed percutaneous transhepatic abscess drainage (PTAD). Three days after PTAD, we then performed sigmoidectomy. Subsequently, the liver abscess resolved and gradually disappeared. At 5 years after surgery, there has been no recurrence of the cancer or abscess.
