Examination of feces and deworming were carried out five times every other month between May 1962 to February 1963 in 5 communities (a total of 202 households, 1, 050 inhabitants) of Urakawa, Sakumamachi, Shizuoka Prefecture. After about a year has elapsed, in which no countermeasures were taken, examination of feces was carried out again in January 1964 to study a change in the rate of positivity. Examination was carried out by the cellophane thick layer smear method (values obtained with two sheets).
(1) The rate of positivity for Ascaris eggs ranged from 13.7% to 55.1%, with an average of 28.0% in the initial examination. The rate was higher in two commnities in the mountainous district. By sex and age, the rate was high among infants, school boys and adult females.
(2) A study of the change in the rate of positivity during the two years has shown that the rates of reinfection and new infcction were higher in communities where the rate of positivity was higher in the initial examination, indicating how difficult it is to exterminate Ascaris infection. On the contrary, there was no substantial rise in the rate of positivity in communities where the rate of positivity in the initial examination was under 10%(3 out of 5 communities), even though no countermeasures were taken during the period of one year. This seems to show that it is not required to carry out deworming frequently.
It has been found that the rate of Ascaris infection was lower in communities where persons positive for unfertilized eggs alone accounted for higher percentages among the total of persons positive for Ascaris eggs, there being a marked inverse corelation between persons positive for unfertilized eggs alone and persons positive for all kinds of Ascaris eggs. There has been a marked tendency to familial concentration of Ascaris infection.
(3) The results of the present study have shown that, in taking measures to exterminate Ascaris infection, it is necessary to take into consideration the rate of positivity for Ascaris eggs, the ratio of persons positive for unfertilized Ascaris eggs to persons positive for all kinds of Ascaris eggs, and a tendency to familial concentration of infection in the community.

Ten athletic women (5 normal ovulatory cycles, 5 short luteal phases) and 6 non-athletic women with normal ovulatory cycles were subjected to an investigation of episodic gonadotropin secretion. In the middle follicular phase, blood samples were obtained via an indwelling venous catheter every 15 minutes for 4 hours.
Mean levels of gonadotropins in both athletic groups were lower (p<0.001) than in the control group. LH pulse frequencies in the short luteal group were significantly lower than in the control group (p<0.001) . LH pulse amplitudes were similar in all groups. FSH dynamics were the same as those for LH.
In athletic women, low mean levels and infrequent episodic secretion of gonadotropins were obvious. These data suggest that strenuous athletic activity may cause hypothalamic-pituitary insufficiency, especially that of hypothalamic origin.

From January of 1987 to December 1992, twelve patients (7 males and 5 females, mean age, 52.8 years) underwent emergency surgery for DeBakey type I acute aortic dissection. The surgical procedure was resection of the initial intimal tear and replacement of the ascending aorta (four patients underwent hemiarch replacement). Operative mortality was 41.7% (5/12). Three died in the operating room due to heart failure (2) and uncontrollable bleeding (1). Another two early deaths resulted from extension of the residual false lumen. All surviving patients each had a patent double-channeled aorta and aneurysmal dilatation of the false lumen was noted in 3 patients. There were two late deaths, one due to rupture of the residual false lumen and the other, to stroke during re-operation for enlargement of the residual false lumen. It is apparent from these results that in type I acute aortic dissection extensive operation such as total arch replacement is necessary.

A 53-year-old man who had angina pectoris and juxtarenal aortic abdominal aneurysm was referred to our department. Because the coronary angiography showed severe triple vessel disease, coronary bypass grafting was performed prior to aneurysmectomy. Contrast enhanced computed tomography revealed a retroaortic left renal vein located behind the posterior wall of the aneurysm. The postoperative course was uneventful. Because of its complicated embryological development, the anatomy of the renal veins shows extensive variability. The incidence of retroaortic left renal vein was 2%. Large lumbar and retroperitoneal veins often joined it to form a complex retroaortic venous system. These veins are particularly vulnerable to injury during circumferential dissection of the proximal parts of the aorta. Unawareness of this anomaly and vigorous attempts at encircling the aorta with clamps can result in laceration of the vein. Subsequent catastrophic hemorrhage may lead to unfavorable results, nephrectomy or death. Therefore, preoperative evaluation by a contrast enhanced CT scan and adequate intraoperative management based on a understanding of the potential anatomical variations are imperative. We recommend crossclamp of the aorta proximally with a vertical clamp to avoid circumferential dissection with possible injury to a retroaortic left renal vein. Injury may necessitate division of the aorta to obtain exposure for venous repair. In addition, this anomaly may be related to aorto-left renal vein fistula syndrome and left renal vein entrapment syndrome.

[Objective]Mie University Hospital Department of Anesthesiology established an integrated acupuncture care clinic in April 2010. A total of 8 incidents and accidents occurred during a period of eight months from commencement in April through November of 2010.
Re-examination of the issues from the incident and accident reports, led to the creation of a clinical manual for the acupuncture clinic as a means to improve the safety of the acupuncture clinic.
[Methods]Based on the contents of the reported incidents, which were collected from electronic medical records up to November 1st 2010, a safety manual was created for the prevention of recurring incidents and accidents. Following a request for approval to the Safety Division of Mie University Hospital, the safety manual underwent screening and inspection and was eventually approved.
After the introduction of the manual, the occurrence of incidents and accidents, was tracked using electronic medical records for a period of four months from December 2010 to March 2011.
[Results]The incidents and accidents that occurred before the creation of the manual were all related to acupuncture (dropped acupuncture needles: 5, needles taken home: 1, and leaving needles inserted: 2). Incidents and accidents have not been reported since the introduction of the manual, that is, for a period of four months from December 2010 to March 2011.
[Conclusion]Clinical practice based on the manual suggests the possibility of preventing incidents and accidents, as none have been reported since the introduction of the manual. The safety manual is still incomplete, as it emphasizes mainly the management of acupuncture and not its entire context. If any further negative incidents or accidents occur, a review and improvement of the present manual will be required. In order to deal with any new negative incidents or accidents, organizing a team will be indispensable.
Since Mie University Hospital has an established Safety Division, soliciting the cooperation of the infectious disease control and medical safety experts to ensure safe clinical practices in the acupuncture core clinic should also be arranged.
The results suggest that the creation of a safety manual can be a means of preventing the occurrence of incidents and accidents.

We have checked into the function of konjak, or the devil's-tongue (Hydrosme vivieri) to reduce cholesterol in order to cast light on its significance as a health food. We processed chipped glucomannan into crackers (hereinafter referred to as “mannan crackers”) and examined its impacts on lipid metabolism. Enrolled for this study were hospital staff members whose total cholesterol exceeded 200mg/dl and students boarding in the hospital's nursing college.
The findings attested to the fact that the intake of mannan crackers may serve to reduce the values of total cholesterol. The higher the value of total cholesterol before this study, the greater the drop. Since we could not detect any effect on either HDLcholesterol or triglyceride, the mannan crackers were considered capable of specifically reducing LDL-cholesterol. We observed no numerical changes in the complete blood cell count (CBCC) and blood chemistry, either. Some of the subjects had abdominal swelling, diarrhea and other digestive problems but theirs were not serious cases. Yet in another aspect, there was no difference in body weight between before and after this study, but the intake of energy and lipid dropped during the period, suggesting that the intake of mannan crackers would produce an effect on the dietary pattern. Having said that, konjak (mannan crackers) may be considered capable of directly or indirectly reducing cholesterol, particularly LDL-cholesterol, suggesting that mannan crackers are of significance as a health food.
The significance of this study for agriculture and rural community must not go unmarked. This study will contribute to the development of agriculture as an industry, while the farm product by the name of konjak has something to do for health, and will be instrumental in protecting the rural environment, not to mention the lives of farm workers engaged in its production. It is a task for us to grapple with by associating itself with farm work and rural villages with the close collaboration of those farm producers.

OBJECTIVE: There is no research regarding the appropriate antiemetic agents for female patients, especially those receiving moderately emetogenic chemotherapy (MEC). We evaluated the antiemetic efficacy of a combination of 5-HT3 receptor with/without aprepitant in patients with gynecological cancer treated with the TC (paclitaxel and carboplatin) regimen of MEC. METHODS: We enrolled 38 patients diagnosed with gynecologic cancer and scheduled to receive the TC regimen. The patients were randomly assigned to receive a 5-HT3 receptor antagonist, either palonosetron in the first cycle followed by granisetron in the second cycle or vice versa. In the third cycle, all patients received a combination of the 5-HT3 receptor and dexamethasone with/without aprepitant. RESULTS: When three drugs were administered, palonosetron consistently produced an equivalent complete response (CR) rate to granisetron in the acute phase (89.5% vs. 86.8%, p=0.87) and delayed phase (60.5% vs. 65.8%, p=0.79). With regard to the change in dietary intake, palonosetron exhibited similar efficacy to granisetron in the acute phase (92.1% vs. 89.4%, p=0.19) and delayed phase (65.7% vs. 68.4%, p=0.14). However, in the delayed phase, the addition of aprepitant therapy with a 5-HT3 receptor antagonist and dexamethasone produced a higher CR rate than a 5-HT3 receptor antagonist with dexamethasone (93.3% vs. 47.8%, p<0.001) and allowed the patients to maintain a higher level of dietary intake (93.3% vs. 56.5%, p<0.001). CONCLUSION: The addition of aprepitant therapy was more effective than the control therapy of a 5-HT3 receptor antagonist, and dexamethasone in gynecological cancer patients treated with the TC regimen.

Obesity may be the consequence of various environmental or genetic factors, which may be highly correlated with each other. We aimed to examine whether grandmaternal and maternal obesity and environmental risk factors are related to obesity in daughters. Daughters (n = 182) recruited from female students, their mothers (n = 147) and their grandmothers (n = 67) were included in this study. Multivariable logistic regression was used to analyze the association between the daughter's obesity and maternal, grandmaternal, and environmental factors. Maternal heights of 161-175cm (OD: 8.48, 95% CI: 3.61-19.93) and 156-160 cm (2.37, 1.14-4.91) showed positive associations with a higher height of daughter, compared to those of 149-155 cm. Mothers receiving a university or a higher education had a significant OR (3.82, 1.27-11.50) for a higher height of daughter compared to those having a low education (elementary school). Mother having the heaviest weight at current time (59-80 kg, 3.78, 1.73-8.28) and the heaviest weight at 20 years of age (51-65 kg, 3.17, 1.53-6.55) had significant associations with a higher height of daughters, compared to those having the lightest weight at the same times. There was no association between the height, weight, and BMI of daughters and the characteristics and education of her grandmothers. In conclusion, although genetic factors appear to influence the daughter's height more than environmental factors, the daughter's weight appears to be more strongly associated with individual factors than the genetic factors.

Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly. Although asymptomatic in most cases, with the anomaly only being detected incidentally, surgical correction should be considered before onset of severe myocardial ischemia in such cases. Here, we present a 70-year-old man who was referred to our department due to chest pain on effort and was given a diagnosis of ARCAPA concomitant with mild aortic stenosis. As the symptoms and the degree of aortic stenosis deteriorated during follow-up, the patient underwent direct re-implantation of the right coronary artery into the ascending aorta and aortic valve replacement. The patient's postoperative course was uneventful, and the symptoms disappeared. Postoperative myocardial perfusion scintigraphy revealed improvement of the myocardial ischemic area.
