Background/Aims: ManoScan and Sandhill high-resolution manometry (HRM) systems are used worldwide; however, the diagnosis of achalasia on the Starlet HRM system is not fully characterized. Furthermore, the impact of calcium channel blockers and nitrites in treating achalasia has not been investigated using HRM. Management of recurrent cases is a priority issue, although few studies have examined patient characteristics. Methods: We conducted a multicenter, large-scale database analysis. First, the diagnosis of treatment-naive achalasia in each HRM system was investigated. Next, patient characteristics were compared between type I-III achalasia, and the impact of patient characteristics, including calcium channel blocker and nitrite use for integrated relaxation pressure (IRP) values, were analyzed. Finally, patient characteristics with recurrent achalasia were elucidated. Results: The frequency of type I achalasia with Starlet was significantly higher than that with ManoScan and Sandhill HRM systems. In achalasia, multivariate analysis identified male sex, advanced age, long disease duration, obesity, type I achalasia, and sigmoid type as risk factors related to normal IRP values (< 26 mmHg). Calcium channel blockers and nitrites use had no significant impact on the IRP values, although achalasia symptoms were indicated to be alleviated. In recurrent cases, the IRP value was significantly lower, and advanced age, long disease duration, and sigmoid type were more common than in treatment-naive patients. Conclusions We should cautiously interpret the type of achalasia and IRP values in the Starlet HRM system. Symptoms of recurrent cases are related to disease progression rather than IRP values, which should be considered in decision making.

Objective: The use of generic drugs is promoted to reduce medical costs and copayments. However, tumor agents are expensive and generic drugs are not widelyused. Thus, it is necessaryto evaluate the safetyof generic drugs in more detail. We compared the incidence of adverse events between the original drug (Gemzar®: GEM) and generic drug (Gemcitabine [Sandoz]: GE-GEM) using propensityscore (PS) matching.Methods: We investigated adverse events in patients who received one course of GEM or GE-GEM. The patient background (age,sex, BSA, cancer type, stage, metastasis, surgical history, and radiotherapy) and administration status (administration route and RDI) were used to calculate the PS.Results: Among all patients (GEM: 51, GE-GEM: 54), a significantlygreater number in the GE-GEM group had cancer metastasis. On comparison of adverse events, there were significantlymore cases of vascular pain (p＜0.05) in the GEM group, and manycases of nausea (p＝0.08) and rash (p＝0.08). Fortypatients in each group were extracted byPS matching. There were no significant differences in the patient background between the groups, and on comparison of adverse events, the two groups did not significantly differ.Conclusion: Our studysuggested that there is no difference in side effects between Gemzar® and gemcitabine [Sandoz]. To compare the incidence of adverse events, it is useful to use PS matching in clinical practice.

Objective: The purpose of this study was to clarify the factors related to gemcitabine (GEM)-induced phlebitis. Methods: We retrospectively analyzed 400 cases of intravenous GEM administration to 50 patients from June 2014 to May 2015. We assessed the relationship between GEM-induced phlebitis and various factors including age, sex, BMI, analgesic use (NSAIDs or opioids), and GEM-administration procedures including drug formulation, dosage, and access site. Results: Phlebitis occurred in 79 cases (19.8%). Multivariate analysis indicated that sex (female), age (<65 years old), BMI (≥25 kg/m2; obesity), drug formulation (liquid), and access site (dorsal hand vein) were significantly related to the presence of phlebitis. Discussion: GEM-administration procedures should be modified in patients with these risk factors. It is desirable to apply hot fomentation and to puncture at the brachial region or cubital fossae region vein to prevent phlebitis.

Effects of three plant extracts (Hordeum vulgare L., Apocynum Venetum L., Brasenia schreberi J.F.G mel.) on human gingival fibroblasts were examined. As a result, we observed the promoting effect of the extract of Hordeum vulgare L. and the extract of Apocynum Venetum L. respectively on FGF2 and FGF7 production. Moreover, the mixture of the three plant extracts showed the effect of improving the changes in type I collagen gene expression and matrix metalloproteinase 1 gene expression by LPS addition. Next, a dentifrice containing the three plant extracts was subjected to human efficacy trials. We measured periodontal pocket depth, attachment level, bleeding on probing and saliva TNFα as an indicator of periodontal disease. The results suggest that the dentifrice formulated with the three plant extracts were effective for the improvement of periodontal disease.

The role of nodal station No. 14v (along the superior mesenteric vein) in lymphadenectomy for distal gastric cancer remains elusive. A 73-year-old woman underwent endoscopic submucosal dissection for gastric cancer, and was referred to our division for additional surgery because of pathologically non-curative resection. A laparoscopic distal gastrectomy with D1+ dissection was performed, with a final diagnosis of pT1bN1M0, Stage IB (2 nodal metastases to No. 6). Four months post-surgery, abdominal computed tomography revealed a 14-mm solitary nodule along the superior mesenteric vein. The lesion was excised and pathologically identified as a lymph node metastasis. Adjuvant chemotherapy with tegafur-gimeracil-oteracil potassium (S-1) was administered for the metastasis. Presently the patient survives without recurrence, 5.5 years after the second operation. Our findings suggest that there is lymphatic flow from the No. 6 to the No. 14v nodal station. Some patients with a No. 6 metastasis may benefit from a No. 14v lymphadenectomy, even in early-staged disease.

As of 2011, about 12.8 million people in Japan had osteoporosis, which is a social issue in that it increases the number of patients who are bedridden or require residential care and its poor prognosis increases the mortality rate. We delivered a presentation on osteoporosis prevention to residents;the presentation consisted of ultrasound bone densitometry readings followed by a slide show, based on the readings. This report summarizes the presentation and considers whether it was effective in enhancing awareness of osteoporosis. The presentation was given to 39 residents, who were asked to complete a questionnaire before and after it. Of the 31 female respondents, 16.1 percent had bone density in the “low or caution” range;for all eight male respondents, it was “sufficient” or “average.” After the presentation, over 90 percent of respondents selected “agree” or “slightly agree” in response to the statements “I want to have regular exercise and participate in sports,” “I want to eat nutritionally sound meals,” and “understanding one’s bone density is useful for the prevention of osteoporosis.” In addition, 97.4 percent of the residents responded that the lecture was “useful” or “somewhat useful,” and 94.9 percent indicated satisfaction with it. The presentation was considered to be useful in enhancing residents’ awareness of osteoporosis.

OBJECTIVETo study the effect of endocrine disruptor chemicals in cow milk on female reproductive system.

METHODSA two-generation reproduction was conducted according to U. S. FDA standard. Milk was fed in special bottle to Wistar rats of both sexes through two successive generations (F0 and F1) in the milk group while artificial milk was fed to rats in the control group. Twenty-four rats of each sex were mated in each group. Measurements were made according to this guideline.

RESULTSReproductive parameters in the milk group such as fertility index, gestation index, weights of uterus and ovary, days of vaginal opening, estrous cycles, histological morphological changes were comparable to those in the control group. However, the means of body weight had some differences. The body weight gains increased significantly in the milk-treated group in F1 and F2 generation compared with those in the control group. The concentration of insulin-like growth factor-1 (IGF-1) in blood in the milk group was comparable to that in the control group, but the standard deviation changed greatly in the milk-treated rats.

CONCLUSIONEndocrine disruptor chemicals in milk have no severe effects on the female reproductive system.

OBJECTIVESTo study the effects of estrogen-like products in milk on the male reproductive system.

METHODSThe incidence rates of testicular and prostatic cancers in 42 countries (regions), collected from the cancer incidence in five continent database (1988-1992), were correlated with the relative food consumption in these countries, which was provided by FAO database (1961-1990); two-generation reproduction test was taken by using Wistar rats according to FDA standard.

RESULTSAmong the food items examined, milk was most closely correlated (r = 0.711) with prostatic cancer incidence, followed by meat and coffee. As for testicular cancer, cheese was most closely correlated (r = 0.804) with the incidences in ages of 20-39, followed by animal fat and milk. No significant decreases of reproductive organ weight were found after the rats had been fed a lot of milk for long time.

CONCLUSIONSThe results suggest that further studies should be taken on the effects of estrogen-like products in milk on the male reproductive health.

Because Japanese high school graduates have poor basic English skills they have difficulty acquiringduring the 6 years of medical school English skills sufficient to write medical papers in easily understood English and to converse with foreign medical researchers at international medical conferences in fluent English. In an attempt to improve English teaching in medical schools we analyzed the structures of sentences in high school English textbooks and compared them with those of sentences in more advanced English, as in the journals Science and Nature. We found that the English in high school textbooks has significantly lower subordination ratios. Thus, we propose that English with higher subordination ratios be taught in the 1st year of medical school.

A 61-year-old man was found to have an abdominal aortic aneurysm (AAA) during follow-up for ischemic heart disease. On admission, ultrasonograms and computed tomograms revealed a thickened aortic wall surrounded by a soft tissue (so-called mantle). The obstructive right anterior brain artery and stenotic right internal carotid artery were also detected by angiography. Coronary angiography demonstrated multiple stenotic lesions of the coronary arteries. The excised AAA was replaced with an prosthetic graft. The mobilization of the adjacent viscera was kept as little as possible in order to prevent injury to them. We reported a case of “inflammatory” abdominal aneurysm associated with various atherosclerotic lesions.
