Herb supplies can become unstable because of climate change and the economic development of herb exporters. In this paper, in order to increase the self-sufficiency of herbal resources we examined the possibil ity of changing to herb crop production from tobacco, for which demand is declining. Firstly, we considered demand, quality and the price of raw herb materials to make recommendations for corrections, and selected Angelica (A. ) acutiloba and Bupleurum (B. ) falcatum Linne. Next, we compared the profitability of tobacco and the herbs. Profit margins for A. acutiloba were less than for tobacco. It was thought that the profitability of A. acutiloba could become equivalent to tobacco if an adjustment subsidy were provided. The self-sufficiency rate for A. acutiloba would be one hundred percent with 35 million yen in every year. Although the profitabil ity of B. falcatum has exceeded tobacco, its selling price was about 3 times that of imports, while the price of medical B. falcatum was lower than its selling price. It was thought that the price competitiveness problem of B. falcatum can be covered if a production subsidy is provided, and to reach a 50 percent B. falcatum self sufficiency rate with 660 million yen per year.

A 69-year-old man, who had undergone coronary artery bypass grafting using the right gastroepiploic artery 2 years previously, was hospitalized with acute epigastralgia. Gastroscopy showed an early gastric cancer in the greater curvature of the corpus and ultrasonography of the abdomen revealed acute cholecystitis due to a stone impacted in the cystic duct. The subtotal gastrectomy and the cholecystectomy with preservation of the right gastroepiploic artery graft were performed. The surgical margin of the resected specimen was negative for cancer. The postoperative course was uneventful. After coronary artery bypass grafting using the right gastroepiploic artery, annual gastroscopy is recommended.

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.

STUDY DESIGN: Prospective comparative study. PURPOSE: To compare the incidence and severity of adverse reactions associated with myelography performed in outpatients vs. in inpatients and report the safety and usefulness of outpatient myelography in Japanese patients. OVERVIEW OF LITERATURE: Myelography is normally performed as an inpatient procedure in most hospitals in Japan. No studies have reported the usefulness and adverse effects of outpatient myelography in Japanese patients. METHODS: We performed 221 myelography procedures. Eighty-five of the 221 patients underwent outpatient myelography using our new protocol. The incidence and severity of adverse reactions were compared with the other 136 patients, who underwent conventional inpatient myelography. We further compared the cost of outpatient and inpatient myelography. RESULTS: The overall rate of adverse effects was 9.4% in outpatients, as compared with 7.4% in inpatients. Overall, 1.2% of outpatients and 0.74% inpatients experienced "severe" adverse effects (requiring hospitalization). There were no significant differences between the 2 groups in either the overall rate of adverse effects or the rate of "severe" adverse effects. Moreover, the average outpatient procedure cost was only one-third to one-half that of the inpatient procedure. CONCLUSIONS: This was the first study to address the safety and usefulness of outpatient myelography in Japanese patients. If selected according to proper inclusion criteria for outpatient procedure, no significant differences were observed in the adverse effects between inpatients and outpatients. The outpatient procedure is more economical and has the added benefit of being more convenient and time-efficient for the patient.

OBJECTIVE: To determine the safety and usefulness of a two-tiered approach to balloon-occluded retrograde transvenous obliteration (B-RTO) as a treatment for large gastric varices after portal hypertension. MATERIALS AND METHODS: 50 patients were studied who underwent B-RTO for gastric varices between October 2004 and October 2011 in our institution. The B-RTO procedure was performed from the right femoral vein and the B-RTO catheter was retained until the following morning. Distribution of sclerotic agents in the gastric varices on fluoroscopy was evaluated in all patients on days 1 and 2. When distribution of sclerotic agents in the gastric varices on day 1 had been none or very scanty even though the volume of the sclerotic agent infused was above the acceptable level, a second infusion was administered on day 2. When distribution was satisfactory, the B-RTO catheter was removed. RESULTS: In 8 (16%) patients, little or no sclerotic agent infused on day 1 was distributed in the gastric varices. However, on day 2, sclerotic agents were distributed in all gastric varices. Mean volume of ethanolamine oleate-iopamidol infused on day 1 was 24.6 mL and was 19.4 mL on day 2. Gastric varices were well obliterated with no recurrence. Complications caused by the sclerotic agent such as pulmonary edema or renal insufficiencies were not seen. CONCLUSION: When gastric varices are very large, a strategy involving thrombosis of only the drainage vein on the first day followed by infusing the sclerotic agent on the following day might be effective and feasible.

STUDY DESIGN: Retrospective study (level of evidence=3). PURPOSE: We examine the relationship between residual symptoms after discectomy for lumbar disc herniation and peripheral nerve (PN) neuropathy. OVERVIEW OF LITERATURE: Patients may report persistent or recurrent symptoms after lumbar disc herniation surgery; others fail to respond to a variety of treatments. Some PN neuropathies elicit symptoms similar to those of lumbar spine disease. METHODS: We retrospectively analyzed data for 13 patients treated for persistent (n=2) or recurrent (n=11) low back pain (LBP) and/or leg pain after primary lumbar discectomy. RESULTS: Lumbar re-operation was required for four patients (three with recurrent lumbar disc herniation and one with lumbar canal stenosis). Superior cluneal nerve (SCN) entrapment neuropathy (EN) was noted in 12 patients; SCN block improved the symptoms for eight of these patients. In total, nine patients underwent PN surgery (SCN-EN, n=4; peroneal nerve EN, n=3; tarsal tunnel syndrome, n=1). Their symptoms improved significantly. CONCLUSIONS: Concomitant PN disease should be considered for patients with failed back surgery syndrome manifesting as persistent or recurrent LBP.

Background: We retrospectively compared endscopic gastroduodenal stenting with gastrojejunostomy as a means of palliating malignant gastric and duodenal obstruction. Methods: This retrospective study investigated patients treated for malignant gastric and duodenal obstruction from April 2011 to April 2015 at Shikoku Cancer Center. Results: Of the 40 patients in this study, 25 underwent gastroduodenal stenting and 15 had operative gastrojejunostomy. Comparing the stenting and operative patients, technical success rate was 100% in both group, clinical success rate was 84% in stenting patients and 93% in operative patients. The median time to fluid intake was significantly shorter in stenting patients than operative patients(0 day vs 2 days, p=0.0003), and the median time to intake of solids was also significantly shorter in stenting patients(1day vs 3 days, p<0.0001).The median hospital stay was significantly shorter in stenting patients(9 days vs 23 days, p=0.0116). Median cost of hospitalization is more expensive in operative patients than stenting patients(¥1,106,170 vs ¥752,290, p=0.0052). Conclusion: Our study suggested that gastoroduodenal stent was less length of time to fluid/solid intake, and less costly than gastrojejunostomy.

PURPOSE: Thoracic dumbbell tumors are relatively rare, usually arising from neurogenic elements. Methods for surgical removal thereof remain controversial. The purpose of this study was to evaluate the surgical results of a single-stage posterior approach with laminectomy and costotransversectomy only for the management of thoracic dumbbell tumors. MATERIALS AND METHODS: Eight cases of thoracic large dumbbell tumor were analyzed retrospectively: seven men and one woman (mean age, 49 years). Pathologic findings included schwannoma in five patients, neurofibroma in two patients (Recklinghausen in one patient), and ganglioneuroma in one patient. All patients underwent single-stage removal of dumbbell tumors by a posterior approach followed by laminectomy and costotransversectomy combined with instrumentation. Clinical and radiologic outcomes were reviewed, thereafter. RESULTS: Operative time ranged from 185 to 420 minutes (mean, 313 minutes), with estimated blood loss ranging from 71 to 1830 mL (mean, 658 mL). Postoperative complications included atelectasis in one case. All patients had tumors successfully removed with no neurological deterioration. Spinal deformities were not observed in any patients at the last follow-up (mean, 52 months), with instrumentation. CONCLUSION: Single-stage surgery with laminectomy and costotransversectomy may be useful for removing thoracic dumbbell tumors without a combined anterior approach.

Thoracic ossification of the ligamentum flavum (T-OLF) is a relatively rare spinal disorder that generally requires surgical intervention, due to its progressive nature and the poor response to conservative therapy. The prevalence of OLF has been reported at 3.8%-26%, which is similar to that of cervical ossification of the posterior longitudinal ligament (OPLL). The progression of OPLL after cervical laminoplasty for the treatment of OPLL is often shown in long-term follow-up. However, there have been no reports on the progression of OLF following surgery. We report a case of thoracic myelopathy secondary to the progressive relapse of OLF following laminectomy.

Background: The demand for palliative care in Japan has risen over recent years, and training of palliative care physicians is an important problem. However, little is known about unmet needs for education and training systems as well as career development among young physicians who wish to specialize in palliative care. Purpose: To explore unmet needs among palliative care physicians in training. Method: We held group discussions in a forum for physicians of postgraduate year≦15, and analyzed their opinion on topics such as "what are unmet needs?" using theme analysis. Results: Forty physicians participated. Theme analysis revealed the following unmet needs among young physicians; "securing of manpower", "securing of quality of training programs/education", "improvement of network", "removal of many barriers to keeping on a palliative care physician", and "establishment of career models for a specialist". Conclusions: We should discuss solutions for the unmet needs to secure more palliative care physicians.
