Objective: We investigated subjective effects of a lactoferrin (LF) -containing supplement on cold-like symptoms and gastroenteritis symptoms.
Method: Healthy women were divided into a LF-consumption group and a non-consumption group. The former intaked LF-containing tablets for 90 days. Subjects filled out questionnaires about cold-like symptoms, gastroenteritis symptoms, and drug use.
Results: Significant decreases were found in the onset of cold-like symptoms and gastroenteritis symptoms in the LF-consumption group compared with non-consumption group.
Conclusion: These results suggest the possibility that LF intake inhibits the onset of common cold and gastroenteritis.

A 48-year-old man with Buerger disease and intractable finger ulcers underwent successful transplantation of autologous peripheral blood-derived mononuclear cells pretreated with erythropoietin and blood donation to activate bone marrow function. Clinical symptoms on his finger ulcers improved significantly within 1 month after mononuclear cell transplantation, however, one of the intractable ulcers reappeared 2 months later. In total three transplantations were performed. Every cell transplantation revealed similar effectiveness 1 month later, and the interval of the subsequent disappearance of finger ulcers ranged from 3–6 months. There were no adverse effects based on this new therapy. These findings suggest that autologous peripheral mononuclear cell transplantation pretreated with erythropoietin and blood donation might be a non-invasive and safe alternatives for patients with Buerger disease and intractable finger ulcers.

  To the best of our knowledge, there are few reports on acquirement of medical skills of infection control using a scenario simulation program. We report the development of a education program using scenario-based simulation named Infection Control Training Course （ICTC）. The three main aims of this course are basic comprehension of standard precautions and contact precautions, acquirement of skills for wearing and removal of personal protective equipment （PPE）, and precise selection of PPE for various situations.
・For the materials and methods, 225 medical staff members taking part in the ICTC at TMU participated in the study. Investigations using a questionnaire about standard precaution, contact precaution and PPE selection were carried out for the pre-course and post-course of the day. In addition, the satisfaction level was evaluated using free score text.
・The return rates of the completed questionnaire for investigating these areas were 88.4% （pre-course） and 95.1% （post-course）. Among all the items investigated, improvements were verified statistically （Wilcoxon signed-rank test）. The satisfaction level was 94.7 ± 9.4 points.
・In conclusion, the ICTC was considered to be effective for acquiring medical skills of infection control, particularly basic comprehension regarding standard precaution, contact precaution and precise PPE selection using a scenario simulation program.

Results: In the early phase after surgery, 71% and 43% of the participants were nonindependent ambulators at 1W and 2W, respectively. Histopathology indicated that patients with solid tumors (ependymoma, astrocytoma, or lipoma) showed significantly lower indices at 1W and 2W than those with vascular tumors (hemangioblastoma or cavernous hemangioma). Regarding tumor location, thoracic cases exhibited poorer lower-limb function at 1W and 2W and poorer walking ability at 2W than cervical cases. According to the receiver operating characteristic (ROC) analysis, 2 WISCI II points at 2W had the highest sensitivity (100%) and specificity (92.2%) in predicting the level of walking independence at 1 year postoperatively (the area under the ROC curve was 0.99 (95% confidence interval, 0.93–1.00). Conclusions The higher the lower-limb function scores in the early phase, the better the improvement in walking ability is predicted 1 year after ISCT resection.

STUDY DESIGN: Retrospective study. PURPOSE: To assess treatment outcomes of snowboarding-related spinal and spinal cord injuries. OVERVIEW OF LITERATURE: Snowboarding-related spinal or spinal cord injury have a great impact on social and sporting activities. METHODS: A retrospective review of 19 cases of surgically treated snowboard-related injury was done. Analyzed parameters included site of injury, type of fracture, peri- and postoperative complications, pre- and postoperative neurological status, activities of daily living, and participation in sports activities at the final follow-up. RESULTS: The major site of injury was the thoracolumbar junction caused by fracture-dislocation (13/19 cases). The remaining 6 cases had cervical spine injuries. Over 60% of the patients had Frankel A and B paralysis. All patients were surgically treated by posterior fusion with instrumentation. Five underwent additional anterior fusion. Surgical outcome was restoration of ambulatory capacity in 12 patients (63.2%). Ultimately, 15 patients (78.9%) could return to work. Patients with complete paralysis upon admission showed reduced ambulatory capacity compared to those with incomplete paralysis. None of the patients again participated in any sports activities, including snowboarding. CONCLUSIONS: Snowboarding-related spinal or spinal cord injury has a great impact on social as well as sports activities. It is necessary to enhance promotion of injury prevention emphasizing the snowboarders' responsibility code.

Objective: To investigate the role of postgraduate clinical training at the emergency department of Tenri Hospital in teaching the diagnostic process in the general outpatient department.
Method: Patients seen by 11 first-year residents at the emergency department were consecutively registered with summary sheets. Further information was added, and an analysis was performed of: 1) the distribution of chief complaints in the emergency and general outpatient departments and 2) initial diagnoses and the diagnostic process in the emergency department and the final diagnoses.
Results: The distributions of chief complaints in 89 cases in the emergency department and in 183 cases in the general outpatient department were closely correlated (p=0.0016). Diagnoses in the emergency department were correct in 58% of cases. Treatment was incorrect in 3% of cases.
Conclusion: The distributions of chief complaints in the emergency and general outpatient departments were similar. In our hospital the emergency department plays a major role in postgraduate clinical training by teaching the diagnostic process for the general outpatient department. Clinical management, including decision making for further tests and consultation, in the emergency department by first year residents did lead to any major adverse events.

OBJECTIVESystemic and myelotoxic effects of 2,3,7,8-tetrabromodibenzo-p-dioxin (TBDD) were examined by the single administration of TBDD by gavage to rats.

METHODSFifteen Wistar rats of both sexes per group received 0, 10, 30, 100 or 300 μg TBDD/kg body weight. Rats surviving to the scheduled necropsy on Days 2, 7 and 36 after TBDD administration were examined for growth rate, organ weight, hematology, histopathology and adipose tissue levels of TBDD.

RESULTSThree 300 μg/kg-dosed females died on Days 21, 23 and 27, and exhibited a marked decrease in body weight, severe thymic atrophy, decreased bone marrow hematopoiesis and hemorrhage in the subarachnoid space of brain and spinal cord. TBDD-dosed surviving rats exhibited growth retardation, decreased bone marrow hematopoiesis, decreases in red blood cell counts, hemoglobin concentrations, and hematocrit values, an increase in reticulocytes and decreases in platelet counts, white blood cell counts and eosinophils. These signs suggested TBDD myelotoxicity. Splenic extramedullary hematopoiesis was increased in both sexes given TBDD, whereas atrophy of the splenic white pulp occurred only in TBDD-dosed females. Marked decreases in body weights and the size and weight of the thymus, severe thymic atrophy and death in TBDD-dosed females suggested a wasting syndrome. The adipose tissue level of TBDD culminated on Day 7 and decreased to 20-30% of the Day 7 level on Day 36.

CONCLUSIONSThe TBDD-induced effects were characterized by a wasting syndrome and myelotoxicity that appeared at the dose levels of 30 μg/kg and higher and caused death in 300 μg/kg-dosed females.

A 74-year-old man having a right refractory foot ulcer was referred to our hospital with a diagnosis of arteriosclerosis obliterans. Angiography of the lower extremities showed occlusive lesions in the middle popliteal artery and lower-leg arteries. Preoperative examination revealed decreased cardiac function and severe stenosis of the left and right coronary arteries. Therefore, we first performed coronary artery bypass grafting, followed by revascularization of the lower limbs at a later date. Owing to the lack of suitable autologous vein grafts, our procedure of choice was popliteal endarterectomy via a posterior approach with short saphenous vein angioplasty. The patient's foot ulcer healed completely following surgery. His postoperative course was uneventful, and he remained symptom-free during a 1-year follow-up.

Background/Aims: The anastomotic site after distal gastrectomy is the area most affected by duodenogastric reflux. Different reconstruction methods may affect the lesion characteristics and treatment outcomes of remnant gastric cancers at the anastomotic site. We retrospectively investigated the clinicopathologic and endoscopic submucosal dissection outcomes of remnant gastric cancers at the anastomotic site. Methods: We recruited 34 consecutive patients who underwent endoscopic submucosal dissection for remnant gastric cancer at the anastomotic site after distal gastrectomy. Clinicopathology and treatment outcomes were compared between the Billroth II and non-Billroth II groups. Results: The tumor size in the Billroth II group was significantly larger than that in the non-Billroth II group (22 vs. 19 mm; p=0.048). More severe gastritis was detected endoscopically in the Billroth II group (2 vs. 1.33; p=0.0075). Moreover, operation time was longer (238 vs. 121 min; p=0.004) and the frequency of bleeding episodes was higher (7.5 vs. 3.1; p=0.014) in the Billroth II group. Conclusions Compared to remnant gastric cancers in non-Billroth II patients, those in the Billroth II group had larger lesions with a background of severe remnant gastritis. Endoscopic submucosal dissection for remnant gastric cancers in Billroth II patients involved longer operative times and more frequent bleeding episodes than that in patients without Billroth II.
