BACKGROUND/AIMS: The gastrointestinal motility effects of endogenous incretin hormones enhanced by dipeptidyl peptidase-IV (DPP-IV) inhibitors have not yet been sufficiently investigated. The aim of this study was to determine whether single pre-prandial sitagliptin, the DPP-IV inhibitor, administration might have an effect on the rate of liquid gastric emptying using the 13C-acetic acid breath test. METHODS: Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects fasted for overnight and were randomly assigned to receive 50 mg sitagliptin 2 hours before ingestion of the liquid test meal (200 kcal per 200 mL, containing 100 mg 13C-acetate) or the test meal alone. Under both conditions, breath samples were collected for 150 minutes following the meal. Liquid gastric emptying was estimated by the values of the following parameters: the time required for 50% emptying of the labeled meal (T1/2), the analog to the scintigraphy lag time for 10% emptying of the labeled meal (Tlag), the gastric emptying coefficient and the regression-estimated constants (beta and kappa), calculated by using the 13CO2 breath excretion curve using the conventional formulae. The parameters between the 2 test conditions were compared statistically. RESULTS: No significant differences in the calculated parameters, including T1/2, Tlag, gastric emptying coefficient or beta and kappa, were observed between the 2 test conditions. CONCLUSIONS: The present study revealed that single-dose sitagliptin intake had no significant influence on the rate of liquid gastric emptying in asymptomatic volunteers.

BACKGROUND/AIMS: The administration of liquid nutrients to patients is often accompanied by complications such as gastroesophageal reflux. To prevent gastroesophageal reflux, high-viscosity liquid meals are used widely, however, it still remains controversial whether high-viscosity liquid meals have any effect on the rate of gastric emptying. The present study was conducted with the aim of determining whether high-viscosity liquid meals had any effect on the rate of gastric emptying and mosapride might accelerate the rate of gastric emptying of high-viscosity liquid meals. METHODS: Six healthy male volunteers underwent 3 tests at intervals of > 1 week. After fasting for > 8 hours, each subject received one of three test meals (liquid meal only, high-viscosity liquid meal [liquid meal plus pectin] only, or high-viscosity liquid meal 30 minutes after intake of mosapride). A 13C-acetic acid breath test was performed, which monitored the rate of gastric emptying for 4 hours. Using the Oridion Research Software (beta version), breath test parameters were calculated. The study parameters were examined for all the 3 test conditions and compared using the Freidman test. RESULTS: Gastric emptying was significantly delayed following intake of a high-viscosity liquid meal alone as compared with a liquid meal alone; however, intake of mosapride prior to a high-viscosity liquid meal was associated with a significantly accelerated rate of gastric emptying as compared with a high-viscosity liquid meal alone. CONCLUSIONS: This study showed that high-viscosity liquid meals delayed gastric emptying: however, mosapride recovered the delayed rate of gastric emptying by high-viscosity liquid meals.

BACKGROUND/AIMS: There are few reports on the correlation between chewing gum and the gastrointestinal functions. But previous report showed use of chewing gum to be an effective method for controlling gastrointestinal symptoms. The aim of this study was to determine the correlation between chewing gum and gastric emptying using the continuous real time 13C breath test (BreathID system). METHODS: Ten healthy male volunteers participated in this randomized, 2-way crossover study. The subjects fasted overnight and were randomly assigned to chewing gum (Xylish, 2-3/1 tablet) for an hour following intake of a test meal (200 kcal/200 mL) or intake of the test meal alone. Gastric emptying was monitored for 4 hours after administration of the test meal by the 13C-acetic acid breath test performed continually using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, T1/2 (median, 111.82 vs 109.26 minutes; P = 0.575), Tlag (median, 53.28 vs 56.53 minutes; P = 0.333), gastric emptying coefficient (median, 3.58 vs 3.65; P = 0.285), regression-estimated constant beta (median, 1.85 vs 1.80; P = 0.575) and regression-estimated constant kappa (median, 0.61 vs 0.62; P = 0.959) were observed between the test meal alone group and the test meal and chewing gum group. CONCLUSIONS: This study showed that chewing gum had no effect on the rate of gastric emptying. Therefore, since chewing gum did not enhance the speed of gastric emptying, it may ameliorate gastrointestinal symptoms through other mechanisms, such as saliva and autonomic nervous system.

Objective: Primary undifferentiated pleomorphic sarcoma (UPS) of the bone is rare. However, the common sites are the knee and proximal femur and humerus, while spinal involvement is rare. We report a case of primary UPS of the 11th thoracic vertebra, where corpectomy would have been difficult and extensive, treated with carbon ion radiotherapy.Case report: A 76-year-old man presented with an osteolytic tumor of the 11th thoracic vertebra on plain computed tomography (CT). The spinal cord was compressed and displaced posteriorly by the tumor on magnetic resonance imaging (MRI), and extraosseous extension was observed. An incisional biopsy was performed, and primary UPS of the 11th thoracic vertebra was diagnosed pathologically. Total en bloc spondylectomy was considered to be challenging because of the extraosseous extension and the patient’s age; thus, carbon ion radiotherapy (70.4 GyE / 32 fraction) was performed. Denosumab (120 mg) was administered subcutaneously every four weeks. No adjuvant chemotherapy was administered. Four years post-treatment, imaging revealed a compression fracture of the 11th thoracic vertebra, but there was no recurrence.Conclusion: Despite a poor prognosis and an aggressive course of UPS of the spine, the tumor continues to be controlled without local recurrence four years after carbon ion radiotherapy.

We report a case of lower back with extremities pain, whose cause could not be established in the medical sense nor relieved by analgesic drugs, was successfully treated with kanzobushito. The patient was a 69-­year-old male. Because of extremity pain of his lower left back, he could not move by himself and was transported to our hospital by an ambulance. Having persistent pain, he could not turn over or stretch his left leg and anal­gesic drugs and sacral nerve blocks were ineffective. We administered kanzobushito referring to the phrase “pain that gets worse as someone approaches” in the Shokanron. After administering kanzobushito, his pain was reduced remarkably and he could sit down on the bed. And his activities of daily living improved immedi­ately. Thus, kanzobushito may be useful for severe pain and should be administered to neuropathic pain compli­cated with psychogenic factors referring to coldness, severe pain and abnormality of qi (irritable).

Orento is generally used for upper gastrointestinal symptoms. We have used orento for various diseases based on “upper heat and middle cold”. As a result of the evaluation of 30 responders to orento, the most frequent sign of “upper heat” was “yellow tongue coating” (29/30 responders), while the most frequent sign of “middle cold” was “preference for warm foods and beverages” (27/30 responders). Compared with the non-­responder group, the responder group showed significantly higher frequencies of “gastrointestinal cold”, which is the sum of “preference for warm foods and beverages” and “aggravation of gastrointestinal symptoms by cold foods and beverages” (29/30 responders, p = 0.047), and “upper/lower gastrointestinal symptoms” (29/30 responders, p = 0.014). These results suggest that “yellow tongue coating” is the most important sign for “upper heat” while “gastrointestinal cold” is the most important sign for “middle cold”. As Kampo patterns for orento, gastrointestinal symptoms often occur, but there is a possibility of upper or lower gastrointestinal symptoms, skin disorders, and sleep disorders.

In this report, we present three cases of lower limb cellulitis. The first case was an 88-year-old woman and the second case was a 36-year-old man. In addition to standard therapy, both of them received Kampo therapies with keishinieppiitto and jidabokuippo during the acute phase of cellulitis and were promptly cured. The third case was a 52-year-old woman with severe obesity suffering from repeated and intractable cellulitis. She received Kampo therapy including keishibukuryogan. The redness and swelling in her leg gradually disappeared. Administration of adequate antibiotics and elevation of affected areas are important for the treatment of cellulitis. Even with appropriate therapy, some patients are slow to respond and difficult to treat. The skin findings in cellulitis are swelling, redness, heat, and pain, which can be recognized and treated as water imbalance, heat, and blood stasis in Kampo medicine. This case report suggests that cellulitis during the acute phase can be treated with keishinieppiitto and the treatment of water imbalance and heat is important. After the acute phase, the treatment of blood stasis is important. Considering the time of onset and skin findings in cellulitis, Kampo therapy can contribute to the rapid recovery of cellulitis.

Mokuboito is usually used for the treatment of patients with dyspnea and edema due to chronic heart failure. We herein report two cases successfully treated with mokuboito on the basis of shinkahiken (epigastric stuffiness and strong resistance). Case 1 was a 28-year-old woman. She had been experiencing occasional bouts of epigastralgia for 12 years, but they had worsened two months before the first visit to our department. When she was examined, however, the cause of epigastralgia could not be determined and she was diagnosed with functional gastroenteropathy. After being introduced to our department, she was treated with various Kampo formulas, but the symptom was poorly improved. Case 2 was a 74-year-old man who was prescribed hachimijiogan and shoseiryuto for an overactive bladder and perennial allergic rhinitis. His symptoms were stable, but suddenly deteriorated after two months. In both cases, when changing treatment to mokuboito on the basis of shinkahiken, the symptoms were improved. These results suggest that mokuboito can be used in a wide range of cases with shinkahiken.

Five cases of various diseases associated with breast cancer treatment including arthralgia, menopausal symptoms, chemotherapy-­associated symptoms (nausea, vomiting, numbness, pain, general fatigue), and anxi­ety neuroses during follow-­up were treated with Kampo medicine and a favorable course was obtained. Com­bined use of Kampo treatment can reduce the suffering caused by the side effects of breast cancer treatment, alleviate mental symptoms, prevent recurrence, and improve the patients' health. Kampo medicine plays a role in cancer supportive care for breast cancer.
