Objective To observe the impact of zotepine on the excitatory synaptic response and long term potentiation (LTP) of dentate gyrus neurons.Methods Male rabbits ( n = 20) weighting about 2.5 ~ 3.5 kg were divided into four groups randomly ( n = 5 ): control, zotepine 1.0, zotepine 2.0 and zotepine 5.0.To each rabbit,there were 60 results during 120 min.Population spike(PS) amplitude and excitory postsynaptic potential (EPSP) slope were used to be the indexes of the excitatory synaptic response of dentate gyrus neurons.The sequence was base response ( at the beginning), intraperitoneal injection of 0.5ml dimethylsulfoxide or 0.5ml zotepine-dimethylsulfoxide solution ( 1.0,2.0,5.0 mg/kg of zotepine dosage) ( after 30 min) and titanic stimulation (after 90 min).Results To 4 groups,the PS amplitude and EPSP slope after single stimuli were not significantly different from those before single stimuli.In control group, the PS amplitude and EPSP slope after titanic stimulation[(0.68 ± 0.052)mV and(0.633 ± 0.024 )mV/ms] were significantly different from those before injection[(0.266 ±0.008) mV and(0.246 ±0.010) mV/ms] (P<0.05 ~0.01 ) ,and LTP were induced.LTP were not induced after titanic stimulation in group zotepine 1.0,2.0 and 5.0.After titanic stimulation, the PS amplitude and EPSP slope in group zotepine 5.0[(0.277 ±0.008)mV and(0.296 ±0.007) mV/ms] were significantly different from those in group control(P< 0.05).Conclusion Zotepine had little effect on the excitatory synaptic response of dentate gyrus neurons after single stimuli in perforant path, while it blocked the induction of LTP in perforant path-dentate gyrus pathway.

Using a highly concentrated CO2-bathing, authors studied an effect of the bathing (CO2: 1, 000ppm, for 10min at 40°C) on circadian blood pressure in six cases of antihypertensive drug-refractory hypertension. The patients were females, ranging from 62 to 70 years old (mean age: 65.8±2.6). All of the patients were diagnosed as the III stage of essential hypertension (according to WHO criteria) and have been treated with captopril, nifedipine or α-methyl DOPA since three to ten years ago. Out of six cases five showed non-dipper pattern in circadian blood pressure. All bathings were done at 16:30 and comparative study of circadian blood pressure between plain water and CO2-bathing was carried out.
The results obtained were as follows.
1) In five cases of non-dippers CO2-bathing exerted the therapeutic effect upon the high blood pressure at night and resulted in the significant decrease in hyperbaric indici of systolic, mean and diastolic blood pressure, comparing with plain water-bathing. However, no significant difference of heart rate was observed between plain water and CO2-bathing.
2) In a case of good responder to antihypertensive drug, a relatively low blood pressure continued all day after CO2-bathing.
From these results it is expected that a highly concentrated CO2-bathing is useful as supportive therapy to essential hypertension, specially to non-dipper.

Objectives: The purpose of this study was to investigate current fact of cancer outpatients’ opioid pain management and its possible abusive applications and to establish corrective treatments by the palliative care team. Methods: Our palliative care team investigated cancer outpatients’ prescribed opioid clinical records for 4 months in 2014, and the result revealed inappropriate opioid use which could lead to further abuse or dependency. Through this the team recommended attending physicians viable options including decrease of opioid eventually leading to final withdrawal. Results: Among 67 cancer outpatients, the finding of inappropriate opioid use which could lead to further abuse or dependency was in 5 patients (7.4%). The details are as follows: (1) Three patients were treated with opioid analgesia for initial pain relief but the application continued in spite of recovering from a cancer which had been responsible to the pain. (2) Two patients were medicated with opioid for pain but further diagnosis revealed the disease which caused pain was benign. Four out of 5 patients were successfully withdrawn from opioids. Conclusion: In cancer outpatient settings, it can be overlooked or undetected inappropriate use of opioids which may lead to abuse or dependency without a team approach. To prevent opioid abuses, it is imperative to find the cause of pain as accurately as possible.

Intramural colonic hemorrhage is rare and often secondary to trauma or anticoagulation therapy. Idiopathic intramural hemorrhages in the alimentary tract have rarely been reported. While several reports of spontaneous perforation of an intramural rectal hematoma have been published, no reports of spontaneous perforation in the ascending colon due to a hematoma have. We describe a patient with an ascending colonic perforation secondary to spontaneous intramural hemorrhage. The patient is a 35-year-old male, who presented with acute abdominal pain and no history of trauma. An abdominal computed tomography scan showed a high-density area around the ascending colon, and nonoperative management was instituted. On the eighth hospital day, the pain worsened, and abdominal computed tomography scan showed free air. An emergent right hemicolectomy was performed. Intramural hematoma and ischemia with perforation, with no obvious etiology, were found. The patient was discharged on the 14th postoperative day.

In the areas of home medical care and self-medication, the role of the pharmacist is growing, partly as a result of Japan’s aging society and the need to reduce medical costs. In response, the Kinki University Faculty of Pharmacy implemented a physical assessment practical training seminar in order to improve the physical assessment skills of practicing pharmacists. A series of questionnaires were conducted among pharmacists to investigate their perceptions of physical assessment practical training seminars. The results of the questionnaires were analyzed using Customer Satisfaction (CS) analysis and text mining. Based on a 5-point scale (1-low∼5-high), questionnaires revealed satisfaction for physical assessment practical training seminars was 4.6±0.6 (Ave.±S.D.). CS analysis revealed that the items “lectures” and “case seminars” had the highest level of satisfaction. However, items showing low levels of satisfaction were “auscultation of respiratory sounds” and “SBAR (Situation, Background, Assessment, Recommendation).” Results of text mining suggested a relationship between “physical assessment” and “difficult”. Analysis of the questionnaires showed a high level satisfaction with physical assessment practical training seminars, notably physical assessment practice methods. However, CS analysis and text mining indicate the finer techniques of physical assessment were difficult to acquire.

Methods:
This prospective, single-arm study included 11 patients (eight men; mean age, 62.7 years) with ≥3-months’ chronic pain history due to lumbar disease. Subcutaneous TCZ injections were administered twice, at a 2-week interval. We evaluated low back pain, leg pain, and leg numbness using numeric rating scales and the Oswestry Disability Index (ODI; baseline and 6 months postinjection); serum IL-6 and tumor necrosis factor-α levels (baseline and 1 month postinjection); and clinical adverse events.
Results:
Intractable symptoms reduced after TCZ administration. Low back pain improved for 6 months. Improvements in leg pain and numbness peaked at 4 and 1 month, respectively. Improvements in ODI were significant at 1 month and peaked at 4 months. Serum IL-6 was increased at 1 month. IL-6 responders (i.e., patients with IL-6 increases >10 pg/mL) showed particularly significant improvements in leg pain at 2 weeks, 1 month, and 2 months compared with nonresponders. We observed no apparent adverse events.
Conclusions
Systemic TCZ administration improved symptoms effectively for 6 months, with peak improvements at 1–4 months and no adverse events. Changing serum IL-6 levels correlated with leg pain improvements; further studies are warranted to elucidate the mechanistic connections between lumbar disorders and inflammatory cytokines.

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: Colonoscopy is useful in diagnosing intestinal tuberculosis. However, the terminal ileum is generally not examined during routine colonoscopy. Therefore, even with colonoscopy, the diagnosis can be missed in patients with lesions confined to the terminal ileum. Herein, we report the case of an asymptomatic patient with intestinal tuberculosis, in whom a colonoscope insertion into the terminal ileum led to the diagnosis.Patient: An asymptomatic 71-year-old man visited our hospital for a colonoscopy after a positive fecal occult blood test.Results: Colonoscopy revealed diffuse edematous and erosive mucosa in the terminal ileum. Mycobacterium tuberculosis was detected by polymerase chain reaction and culture of biopsy specimens from the erosions, leading to the diagnosis of intestinal tuberculosis. The patient was treated with antitubercular agents for 6 months, and a follow-up colonoscopy revealed healing of the lesions.Conclusion: Asymptomatic intestinal tuberculosis may occasionally be detected on colonoscopy following a positive fecal occult blood test and is sometimes confined to the terminal ileum. Therefore, clinicians should consider intestinal tuberculosis in the differential diagnosis of the causes of positive fecal occult blood test results and perform colonoscopies, including observation of the terminal ileum.

Objective:
Several evidence-based practice guidelines have been developed to better treat bipolar disorder. However, the articles cited in these guidelines were based on clinical or basic studies with specific conditional settings and were not sufficiently based on real-world clinical practice. In particular, there was little information on the doses of mood stabilizers.
Methods:
The MUlticenter treatment SUrvey on BIpolar disorder in Japanese psychiatric clinics (MUSUBI) is a study conducted to accumulate evidence on the real-world practical treatment of bipolar disorder. The questionnaire included patient characteristics such as comorbidities, mental status, treatment period, Global Assessment of Functioning (GAF) score, and details of pharmacological treatment.
Results:
Most patients received mood stabilizers such as lithium (n = 1,317), valproic acid (n = 808), carbamazepine (n = 136), and lamotrigine (n = 665). The dose of lithium was correlated with age, body weight, number of episodes, depression and GAF. The dose of valproic acid was correlated with body weight, number of episodes, presence of a rapid cycle and GAF. The dose of carbamazepine was correlated with age, mania, and the presence of a rapid cycle. The dose of lamotrigine was correlated with the number of episodes, depression, mania, psychotic features, and the presence of a rapid cycle. Doses of coadministered mood stabilizers were significantly correlated, except for the combination of valproic acid and lamotrigine.
Conclusion
The dose of mood stabilizers was selectively administered based on several factors, such as age, body composition, current mood status and functioning. Further prospective studies are required to confirm these findings.
