BACKGROUND: The Hokkaido Study on Environment and Children's Health is an ongoing study consisting of two birth cohorts of different population sizes: the Sapporo cohort and the Hokkaido cohort. Our primary objectives are to (1) examine the effects that low-level environmental chemical exposures have on birth outcomes, including birth defects and growth retardation; (2) follow the development of allergies, infectious diseases, and neurobehavioral developmental disorders, as well as perform a longitudinal observation of child development; (3) identify high-risk groups based on genetic susceptibility to environmental chemicals; and (4) identify the additive effects of various chemicals, including tobacco. METHODS: The purpose of this report is to provide an update on the progress of the Hokkaido Study, summarize recent results, and suggest future directions. In particular, this report provides the latest details from questionnaire surveys, face-to-face examinations, and a collection of biological specimens from children and measurements of their chemical exposures. RESULTS: The latest findings indicate different risk factors of parental characteristics on birth outcomes and the mediating effect between socioeconomic status and children that are small for the gestational age. Maternal serum folate was not associated with birth defects. Prenatal chemical exposure and smoking were associated with birth size and growth, as well as cord blood biomarkers, such as adiponectin, leptin, thyroid, and reproductive hormones. We also found significant associations between the chemical levels and neuro development, asthma, and allergies. CONCLUSIONS Chemical exposure to children can occur both before and after birth. Longer follow-up for children is crucial in birth cohort studies to reinforce the Developmental Origins of Health and Disease hypothesis. In contrast, considering shifts in the exposure levels due to regulation is also essential, which may also change the association to health outcomes. This study found that individual susceptibility to adverse health effects depends on the genotype. Epigenome modification of DNA methylation was also discovered, indicating the necessity of examining molecular biology perspectives. International collaborations can add a new dimension to the current knowledge and provide novel discoveries in the future.

We aimed to clarify the significance of using Kampo therapy centered on kamishoyosan and tokishakuyakusan together with general infertility treatment. The subjects were 41 women who visited a Kampo outpatient clinic for infertility and received general infertility treatment with Kampo therapy (Kampo group). The control group was 781 women who received only general infertility treatment at the same time (non-Kampo group). In comparing both groups, we conducted a retrospective survey on the pregnancy rate by cycle and the pregnancy rate by prescription. The pregnancy rate in the first cycle was 24.4% in the Kampo group and 8.5% in the non-Kampo group, and the pregnancy rate was higher in the Kampo group (P = 0.003). There was no difference in pregnancy rates after the second cycle. The pregnancy rate by prescription was 26.7% for kamishoyosan, 22.2% for tokishakuyakusan, and 8.5% for the non-Kampo group. In the comparison between the first cycle pregnant group and the non-pregnant group, the qi counter flow score was clearly higher in the first cycle pregnant group (P = 0.012). It is suggested that combined use of Kampo therapy including kamishoyosan and tokishakuyakusan may be effective from an early stage. Meanwhile, if pregnancy does not occur even after the combined use of Kamp therapy, it would be an opportunity to consider stepping up as Western medical therapy.

A 76-year-old man who suffered from consistent back pain was admitted for anti-hypertensive therapy to strictly manage the early thrombosed acute type A aortic dissection (AAAD). On admission, his blood pressure could not be controlled well ; soon he complained of recurrent severe back pain. The second thoracoabdominal enhanced computed tomography revealed the progression of AAAD from DeBakey type II to type I with thrombosed pseudolumen at the descending thoracic aorta ; therefore, emergent surgical intervention by primary central repair was conducted. Paraplegia was diagnosed eight hours after surgery, then cerebrospinal fluid drainage and intravenous administration of Naloxone were started immediately followed by keeping the systemic blood pressure more than 120 mmHg. However, paraplegia had never improved and been persistent with neurological deficit of the lower extremities. We herein report a complicated surgical case of an AAAD patient with paraplegia and review the complex clinical settings.

BACKGROUND: Pedicled flaps are useful for reconstructive surgery. Previously, we often used vascularized supraclavicular flaps, especially for head and neck reconstruction, but then shifted to using thoracic branch of the supraclavicular artery (TBSA) flaps. However, limited research exists on the anatomy of TBSA flaps and on the use of indocyanine green (ICG) fluorescence videoangiography for supraclavicular artery flaps. We utilized ICG fluorescence videoangiography to harvest reliable flaps in reconstructive operations, and describe the results herein. METHODS: Data were retrospectively reviewed from six patients (five men and one woman: average age, 54 years; range, 48–60 years) for whom ICG videoangiography was performed to observe the skin perfusion of a supraclavicular flap after it was raised. Areas where the flap showed good enhancement were considered to be favorable for flap survival. The observation of ICG dye indicated good skin perfusion, which is predictive of flap survival; therefore, we trimmed any areas without dye filling and used the remaining viable part of the flap. RESULTS: The flaps ranged in size from 13×5.5 cm to 17×6.5 cm. One patient received a conventional supraclavicular flap, four patients received a TBSA flap, and one patient received a flap that was considered to be intermediate between a supraclavicular flap and a TBSA flap. The flaps completely survived in all cases, and no flap necrosis was observed. CONCLUSIONS: The TBSA flap is very useful in reconstructive surgery, and reliable flaps could be obtained by using ICG fluorescence videoangiography intraoperatively.

The prognosis of rhabdomyosarcoma is poor, and its estimated survival is less than year even after radical resection. We report a patient with recurrent rhabdomyosarcoma 11 years after obtaining remission by radical surgical resection and chemotherapy.

We report a case of serous gonarthritis with nonproductive cough successfully treated with Eppikajutsuto. A 37-year-old Japanese man developed a right genicular arthrocele with nonproductive cough, in October X. Over 100 ml of serous synovial fluid was drained via an arthrocentesis puncture procedure. Although he was treated with nonsteroidal anti-inflammatory agents by an orthopedist, under a diagnosis of serous gonarthritis, his symptoms did not improve. Laboratory findings suggested inflammatory conditions (serum CRP 3.4 mg/dl, ESR 76 mm/h). At the time of his first visit in January X+1, orthopedic examinations revealed that rheumatoid arthritis was unlikely, based on negative physical and laboratory findings. A contrast MRI knee joint scan did not demonstrate any tumor-like mass of synovium which would indicate pigmented villonodular synovitis. And orthopedists found it difficult to specify the cause of his serous gonarthritis. After a common cold in December X, cough stimulated by cold exposure was superimposed on serous gonarthritis.We utilized Eppikajutsuto under the interpretation that both his genicular arthrocele and nonproductive cough were due to a “sui” disturbance. This Eppikajutsuto therapy reduced his genicular arthrocele and nonproductive cough in1month. His symptoms and inflammatory reactions were completely improved in 3 months, regardless of gradual withdrawal of his medication.

We demonstrated two patients with fibromyalgia syndrome (FMS), successfully treated with Kampo medicine, and considered the resemblance between the clinical manifestation of FMS and SHO for Kanzo-bushi-to.The first case was a 52-year-old women who consulted a local hospital in 2001 due to althralgia and myalgia in the left hand, bilateral elbows, shoulders and foot. Her condition was diagnosed as FMS without abnormal findings in the thorough medical examination. Treatment with NSAIDs was not effective, so she consulted our department in 2004. She was treated with Keishi-ni-eppi-itto-ka-ryojutsu-ka-boi-ogi-kakkon. After two mouths, her symptoms had reduced to 50% by visual analog scale (VAS). By March 2006, her symptoms had significantly decreased to 20% by VAS and NSAIDs became unnecessary.The second case was a 58-year-old woman who had suffered from tolerable pain in her right elbow for 10 years. In 2004, she visited the Department of Orthology at her local hospital due to pain in the neck, bilateral arms and shoulders. There were no findings on cervical X-ray or neurological examination, and NSAIDs were administered. Her symptoms did not resolve, therefore, she consulted our department in 2005. She was diagnosed with FMS, based on fulfilling the diagnostic criteria for FMS of ACR (American college of rheumatology) in 1990. She was treated with Kanzo-bushi-to. After 3 months, her symptoms had reduced to 30% by VAS. By Mar. 2006, her pain had redused to 25% by VAS and she was physically fit enough for a daily life.

We report a case with an intractable jugular sense of discomfort, with dryness and nonproductive cough successfully treated with soshikokito. A 62-year-old Japanese man developed jugular sense of discomfort with dryness and nonproductive cough, after odontotherapy in October. Although he was treated with Western drugs by an otolaryngologist, under the diagnosis of xerostomia with no mechanical problems, his symptoms did not disappear. The symptoms followed a protracted course, and he further developed a loss of appetite. At the time of first visit in October, otorhinolaryngological studies showed no structural lesions or problems, with the exception of minimum salivation in the normal range on a gum test. There was no evidence of dry eyes. With the diagnosis of xerostomia, Bakumondoto-go-hangekobokuto was administered for a month but showed no sign of improvement. Making a shift to bukuryoin-go-hangekobokuto regained his appetite, but did not produce any improvement on dryness. We then utilized soshikokito under the interpretation that both dryness and nonproductive cough is ki-gyaku. The soshikokito therapy reduced his dryness in a month's time. Additionally, his nonproductive cough gradually decreased, and within 11 months after, he had no symptoms, regardless of a gradual medication withdrawal.

The incidence of fluorosis, believed to arise from the burning of coal, has been frequently reported in the highlands in the southern part of China. With a lot of rain and a climate of low temperature, the hilly region produces coal and inhabitants use it as a fuel for cooking and heating. The fossil fuel used by them is mostly powdery. It is mixed with dirt and rolled up into bolls. In that way,the people make the briquettes that burn a long time.Ordinary houses have no chimneys to belch forth smoke, so that it stagnates indoors for a while. Soot and smoke, before flowing out via the openings in the roof shingle of the loft, spoils farm produce stored there. Because the smoke contains high concentrations of fluoride derived from coal and dirt, it is believed that eating farm produce exposed to the smoke is one of the major factors for fluoride poisoning. Many researchers have thus far analyzed farm products for fluoride content and confirmed that high levels of fluoride were contained in their samples.In the present study, we measured fluoride concentrations in some samples of corn and capsicum produced in a rural area of Sichuan, China on one hand and on the other examined the water-solubility of fluoride. Furthermore, screening tests for chronic endemic dental fluorosis were performed on students to survey the fluoride contamination in the past as compared with the present state.Incidentally, indoor air-borne fluoride concentrations in this area averaged out at0.047mg F/m3 (15 times as high as the mean in a community that was free of fluoride contamination). The fluoride content of the drinking water from a spring in the nearby hill, measured with use of a fluoride-specific electrode method,was within the range from 0.2 to 0.3μg/ml.

A China-Japan joint project was carried out to study the incidence of fluorosis caused by coal burning in China from 1995 to 1997.
The health survey covered a control area and two flourosis areas. In those research areas, drinking water was not polluted with fluorides. The survey was designed to analyze the health status of people exposed to fluorides and evaluate the relationships between the dose and incidence of fluorosis. The concentration of airborne pollutants in both indoor and outdoor air was measured. The concentration of fluoride in the urine was analyzed and definite diagnoses for dental fluorosis and skeletal fluorosis were determined.
As a result, the incidence of coal burning fluorosis was confirmed in studied areas. Moreover, the fluorosis was caused not only by the direct inhalation of the airbone fluorides in indoor air but also by the intake of cereals polluted with fluorides. Fluoride was contained in both coal and soil. Therefore the mixture of coal and soil used for the adjustment of fire energy contributed to the air pollution to a great extent. The typical polluted crops were red pepper, corn and potato. An extremely high concentration of fluoride in the urine of residents in the polluted areas was detected.
