Background/Aims:
Herbal medicine is an important complementary therapy for functional dyspepsia (FD). However, its effect against gastric hypersensitivity in patients with FD has rarely been evaluated. Yokukansan (YKS), a traditional Japanese herbal medicine, is effective against neuropathic and inflammatory pain. This study aims to use a maternal separation (MS) stress-induced FD model to investigate the effects of YKS against gastric hypersensitivity, gastric motility, and duodenal micro-inflammation.
Methods:
The MS stress model was established by separating newborn Sprague-Dawley rats from their mothers for 2 hours a day from postnatal days 1 to 10. At the age of 7-8 weeks, the rats were treated with YKS at a dose of 5 mL/kg (1 g/kg) for 7 consecutive days. AfterYKS treatment, electromyographic activity in the acromiotrapezius muscle by gastric distention and the gastric-emptying rate were assessed. Immunohistochemical analysis of eosinophils in the duodenum and phosphorylated extracellular signal-regulated kinase(p-ERK) 1/2 in the spinal cord was performed.
Results:
YKS treatment suppressed MS stress-induced gastric hypersensitivity and decreased the elevated levels of p-ERK1/2 in the spinal cord.In the gastroduodenal tract, YKS inhibited eosinophil-associated micro-inflammation but did not improve gastric dysmotility.
Conclusions
YKS treatment improved gastric hypersensitivity by alleviating eosinophil-associated micro-inflammation in the gastroduodenal tract.This treatment may be considered an effective therapeutic option for epigastric pain and micro-inflammation in patients with FD.

BACKGROUND/AIMS: Although chronic constipation is a common symptom, to date no international consensus has been reached regarding its definition. The aims of this study were (1) to investigate defecation habits and (2) to examine the prevalence of constipation using the Japanese Society of Internal Medicine (JSIM) and the Rome III criteria using an online survey. METHODS: An online questionnaire composed of items on the frequency, interval, form of defecation, the management, and self-recognition of constipation (reference standard of constipation) was created. A total of 5155 valid responses were received. In addition, constipation symptoms were evaluated through a survey using the JSIM and the Rome III criteria. RESULTS: In the internet survey, 28.4% of the respondents considered themselves to be constipated. Stratified by sex, significantly more females (37.5%) than males (19.1%) considered themselves to be constipated (P < 0.001). The prevalence of constipation among the respondents was 28.0% using the Rome III, but only 10.1% using the JSIM. The diagnostic accuracy was 73.2% for the Rome III and 78.1% for the JSIM, while the diagnostic specificity was 81.1% for the Rome III and 97.5% for the JSIM. However, the diagnostic sensitivities for both measures were low, at 52.2% and 29.2% for the Rome III and the JSIM, respectively. CONCLUSIONS: The online survey developed for this study was able to provide clarification regarding defecation patterns. The results also suggest a discrepancy between the self-recognized prevalence of constipation in Japan and prevalence of constipation based on the JSIM criteria.

BACKGROUND/AIMS: Gastric motility abnormalities have been considered to be pathophysiological features of functional dyspepsia (FD) that are closely related to dyspepsia symptoms, especially postprandial distress syndrome (PDS). The aims of this study are to (1) investigate the prevalence of gastric motility disorders and (2) evaluate the association between gastric motility abnormalities and dyspeptic symptoms using gastric scintigraphy in the PDS type of FD. METHODS: Forty healthy subjects and 94 PDS type FD patients were enrolled in the study. The volunteers and patients ingested a radiolabeled (technetium-99m) solid test meal, and scintigraphic images were recorded. Gastric accommodation and emptying were assessed by scintigraphic imaging. The patients’ dyspeptic symptoms were also explored using self-completed symptom questionnaires with 10 variables (4 scales, 0–3 points) at the same time. RESULTS: In 94 Japanese FD patients, the prevalence of impaired gastric accommodation and delayed emptying were 14.9% (14/94) and 10.6% (10/94), respectively. Gastric motility abnormalities were seen in 25.5% (24/94) of FD patients. There was no association between gastric motility abnormalities and dyspeptic symptoms. CONCLUSIONS: Gastric motility abnormalities were seen in 25.5% of Japanese PDS type FD patients. However, there was no association between gastric motility abnormalities and dyspeptic symptoms on gastric scintigraphy.

Onco-testicular sperm extraction is used to preserve fertility in patients with bilateral testicular tumors and azoospermia. We report the case of a testicular tumor in the solitary testis of a patient who had previously undergone successful contralateral orchiectomy and whose sperm was preserved by onco-testicular sperm extraction. A 35-year-old patient presented with swelling of his right scrotum that had lasted for 1 month. His medical history included a contralateral orchiectomy during childhood. Ultrasonography revealed a mosaic echoic area in his scrotum, suggesting a testicular tumor. The lesion was palpated within the normal testicular tissue along its edge and semen analysis showed azoospermia. Radical inguinal orchiectomy and onco-testicular sperm extraction were performed simultaneously. Motile spermatozoa were extracted from normal seminiferous tubules under microscopy and were frozen. Eventual intracytoplasmic sperm injection using the frozen spermatozoa is planned. Onco-testicular sperm extraction is an important fertility preservation method in patients with bilateral testicular tumors or a history of a previous contralateral orchiectomy.

Introduction: Antiepileptic drugs were occasionally administered to manage seizures in terminally-ill cancer patients. When enteral route is no longer feasible due to dysphagia or depressed level of consciousness, subcutaneous route could be an option. We reported three cases of terminally cancer patients who received subcutaneous levetiracetam (LEV) due to an inability to administer via intravenous route. Cases: The age of 3 cases was 83, 75, 82 years, respectively. In all cases, the prognosis prediction at the start of subcutaneous LEV was about 1 month. In all cases, the route of administration of LEV was changed from intravenous to subcutaneous. No exacerbation of convulsions, or injection site reaction was confirmed after subcutaneous LEV administration. Discussion: We believe that subcutaneous LEV administration may be one of the treatment options for seizures in patients with terminal cancer for whom intravenous administration of LEV is no longer feasible.

Introduction: Our palliative care staff began the support activity in opioid introduction for outpatients with cancer at Komaki City Hospital in March 2018, because it was difficult to make them understand about proper use of opioid analgesics and misinterpretation about abuse at the time of opioid introduction in outpatient settings. This study aimed to evaluate the effects of the activity (patient education on pain control, telephone follow up, and assessment of the symptom). Method: Outpatients with cancer receiving strong opioids for pain relief from January 2017 to March 2019 were eligible. We retrospectively investigated the difference of the variables between baseline and after the activity as follows; the ratios of prescribing immediate-release opioids, antiemetics, and laxatives when opioids were prescribed and side effects due to opioid analgesics appeared. Results: The study included 122 patients. The prescribing ratios of immediate-release opioids antiemetics and laxatives all increased from 90.7 to 98.5%, from 63.0 to 70.6%, and from 61.1 to 70.6%, respectively. The side effect incidence due to opioids with STAS-J 2 or more decreased from 12 (22.2%) to 9 (13.2%). Discussion: The activity could contribute to the provision of drug treatments and counselling needed for opioid therapy.
