:Objective To establish an effective exercise prescription, the exercise capacity of obese subjects was *** In 71 male obese (body mass index: BMI≥26.4) Japanese, aged 26-77 years, the body composition and physical fitness such as aerobic exercise level, muscle strength and flexibility were determined and compared with those of age- and sex-matched 71 borderline (24.2≤BMI<26.4) and 71 normal Japanese men (19.8≤BMI<24.2). The relationship between body composition and other parameters was evaluated in obese *** In obese subjects, body weight, BMI, body fat percentage, waist hip ratio, and skinfold thickness were higher than those of borderline and normal subjects. Lower aerobic exercise level and weight bearing index (WBI) were noted in obese subjects. There was a negative correlation between waist hip ratio and aerobic exercise level (oxygen uptake at ventilatory threshold) (r=-0.509, P<0.01) and also between waist hip ratio and WBI (r=-0.315, P<0.01). Conclusions Lower physical fitness is considered to be a general characteristic of male obese Japanese, and the accumulation of visceral adipose tissue might affect exercise capacity.

2 mm low carbon steel plates were successfully welded by the flat friction stir spot welding(FSSW) using double side adjustable tools, by which the keyhole formed in the conventional FSSW was eliminated and a flat surface on both the top and bottom sides of the welded joints was obtained. In addition, the hook shape usually generated in the conventional FSSW was eliminated by this technique, and the unbonded interface was parallel to the surface of the sheets. Owing to the enlarged bonded interface width by eliminating the keyhole and the intermixed interface by the adjustable probe, the plug fracture occurred under all the welding conditions in the present study. Due to the suppression of the thickness thinning and elimination of the hook shape, the joint performance was improved in the plug fracture mode. The shear tensile performance was considered to strongly depend on the microstructure in the tip area of the unbonded interface and the maximum shear fracture load of 23.0 kN was achieved in this study.

Despite the development of more sophisticated diagnostic techniques, pancreatic carcinoma has not yet been detected in the early stage. Surgical resection provides the only chance for cure or long-term survival. The resection rate has increased due to recent advances in surgical techniques and the application of extensive surgery. However, the postoperative prognosis has been poor due to commonly occurring liver metastasis, local recurrence and peritoneal dissemination. Recent molecular-biological studies have clarified occult metastasis, micrometastasis and systemic disease in pancreatic cancer. Several oncological problems in pancreatic cancer surgery are discussed in the present review.

A retroperitoneal hemangioma is a rare disease. We report on the diagnosis and treatment of a retroperitoneal hemangioma which had uncommonly invaded into both the pancreas and duodenum, thus requiring a pylorus preserving pancreaticoduodenectomy (PpPD). A 36-year-old man presented to our hospital with abdominal pain. An enhanced computed tomography scan without contrast enhancement revealed a 12 cm × 9 cm mass between the pancreas head and right kidney. Given the high rate of malignancy associated with retroperitoneal tumors, surgical resection was performed. Intraoperatively, the tumor was inseparable from both the duodenum and pancreas and PpPD was performed due to the invasive behavior. Although malignancy was suspected, pathological diagnosis identified the tumor as a retroperitoneal cavernous hemangioma for which surgical resection was the proper diagnostic and therapeutic procedure. Reteoperitoneal cavernous hemangioma is unique in that it is typically separated from the surrounding organs. However, clinicians need to be aware of the possibility of a case, such as this, which has invaded into the surrounding organs despite its benign etiology. From this case, we recommend that combined resection of inseparable organs should be performed if the mass has invaded into other tissues due to the hazardous nature of local recurrence. In summary, this report is the first to describe a case of retroperitoneal hemangioma that had uniquely invaded into surrounding organs and was treated with PpPD.

The techniques of evidence-based medicine (EBM) are being frequently used recently. The generally accepted theory is that if a medicine is not absorbed by the body, it will have no effect. However, the author has noticed that even when substances, including medicines, are not absorbed by the body, they can have a marked effect. In some cases, just bringing the substance close to the body can have an effect;in such cases, the efficacy of EBM for estimating the therapeutic value of medicines may be debatable. Therefore, a more accurate evaluation method should be devised. The author proposes that another group be introduced into trials. This group would include subjects who were exposed to but did not have an opportunity to absorb the medicine being tested.

Postoperative pancreatic fistula (POPF) is one of the most severe complications after pancreatic surgeries. POPF develops as a consequence of pancreatic juice leakage from a surgically exfoliated surface and/or anastomotic stump, which sometimes cause intraperitoneal abscesses and subsequent lethal hemorrhage. In recent years, various surgical and perioperative attempts have been examined to reduce the incidence of POPF. We reviewed several well-designed studies addressing POPF-related factors, such as reconstruction methods, anastomotic techniques, stent usage, prophylactic intra-abdominal drainage, and somatostatin analogs, after pancreaticoduodenectomy and distal pancreatectomy, and we assessed the current status of POPF. In addition, we also discussed the current status of POPF in minimally invasive surgeries, laparoscopic surgeries, and robotic surgeries.

This case report illustrates hip joint pain caused by electromagnetic waves following an operation for a complex humerus fracture. The subject was a 22-year-old woman. The patient complained of pain in her left hip joint and discomfort, particularly while walking. The subject suffered a fracture in her left upper arm in a traffic accident approximately 3 months previously. She underwent an operation wherein seven titanium bolts were used to fix the humerus. The operation was deemed successful and the prognosis of the operation was also good;however, approximately 3 months after the operation, she developed pain and discomfort in her left hip joint, particularly while walking. Symptoms were improved by covering the surgical field with aluminum foil, blocking electromagnetic waves. Electromagnetic waves attracted by the titanium bolts may have induced pain.

This case report describes a woman aged approximately 50 years who has suffered from balance dysregulation and dizziness for more than 10 years. Although the subject underwent several examinations to confirm the etiology of her symptoms, the root cause remained unknown. The symptoms were thought to be caused by electromagnetic wave hypersensitivity because the subject experienced uneasiness and dizziness when a cell phone was held close to her body. A cell phone was used to diagnose the collection of harmful electromagnetic waves, and an amalgam filling was determined to be the cause. The amalgam filling was removed under strict protection, and the subject’s symptoms completely disappeared soon after the filling was removed.
