Methods: We enrolled patients who underwent microscopic FMD with outer dural layer resection for CMI. The distance from the tip of the cerebellar tonsil to the C2 vertebral endplate on sagittal magnetic resonance imaging (MRI) was defined as the tonsillar distance (TD). Patients who showed a >20% syrinx diameter reduction on the 1-year follow-up MRI were defined as the syrinx reduction group while the others were categorized in the syrinx nonreduction group. Patients with syringomyelia were categorized into the clinically improved and unimproved groups using the Chicago Chiari Outcome Scale. The imaging and clinical parameters were evaluated pre- and postoperatively. Results: This study included 25 patients of whom 19 (76.0%) had syringomyelia. At the 1-year follow-up, the syrinx diameter had decreased in 11 patients (57.8%). The increased TD significantly differed between the syrinx reduction and nonreduction groups. At the 1-year follow-up, 12 and seven patients with syringomyelia were categorized into the clinically improved and unimproved groups, respectively. The clinically improved and unimproved groups showed significant differences in the mean age and increased TD. Conclusions Postoperative syrinx reduction was significantly correlated with the upward shifting of the cerebellar tonsil in patients with CMI. Our quantitative evaluation of the alterations in hindbrain position after FMD was easily performed and reflects the clinical outcomes.

Methods: We evaluated 100 consecutive surgical patients with CM and divided them into the following groups: 80s (34 patients; mean age, 83.9 years), 70s (33 patients; mean age, 73.9 years), and 69 or younger (33 patients; mean age, 60.9 years). The clinical symptoms and physical signs were evaluated and recorded. Results: Although the recovery rate decreased with increasing age, all groups demonstrated a significant improvement in clinical symptoms relative to preoperative values. The Hoffman sign and hyperreflexia of the triceps tendon were, respectively, present in 82% and 88% of patients in the 80s group, 74% and 64% of those in the 70s group, and 69% and 82% of those in the 69 or younger group, with no significant difference among the groups. In contrast, the rates of hyperreflexia of the patellar and Achilles tendons were, respectively, 59% and 32% in the 80s group, 85% and 48% in the 70s group, and 91% and 70% in the 69 or younger group, with significant differences. Conclusions The positivity rate of the lower extremity hyperreflexia decreased significantly with increasing age in patients with CM. The absence of hyperreflexia, particularly lower extremity, is not uncommon in elderly patients with suspected CM.

STUDY DESIGN: Prospective observational study. PURPOSE: This prospective analysis aimed to evaluate the efficacy and bone-bonding rate of hybrid hydroxyapatite (HA) spacers in expansive laminoplasty. OVERVIEW OF LITERATURE: Various types of spacers or plates have been developed for expansive laminoplasty. METHODS: Expansive open-door laminoplasty was performed in 146 patients with cervical myelopathy; 450 hybrid HA spacers and 41 autogenous bone spacers harvested from the spinous processes were grafted into the opened side of each lamina. The patients were followed up using computed tomography (CT), and their bone-bonding rates for hybrid HA and autogenous spacers, bone-fusion rates of the hinges of the laminae, and complications associated with the implants were then examined. RESULTS: Clinical symptoms significantly improved in all patients, and no major complications related to the procedure were noted. The hybrid HA spacers exhibited sufficient bone bonding on postoperative CT. The hinges completely fused in over 95% patients within 1 year of the procedure. Only 4 spacers (0.9%) developed lamina sinking, and most expanded laminae maintained their positions without sinking or floating throughout the follow-up period. CONCLUSIONS: Hybrid HA spacers contributed to high bone-fusion rates of the spacers and hinges of the laminae, and no complications were associated with their use. Cervical laminoplasty with these spacers is safe and simple, and it yields sufficient fixation strength while ensuring sufficient bone bonding during the immediate postoperative period.

Objective: For effective use of over-the-counter (OTC) drugs that are provided as relief supplies during a disaster, we aimed to develop a list of OTC drugs that can be used during a disaster.
Methods: We obtained information about OTC drugs useful during a disaster by examining results of previous studies and lists of drugs used during a disaster.  We analyzed this information with the expert pharmacist of disaster support and established a rationale for our list and developed “the List of Useful OTC Drugs During a Disaster” and “the Information Card on Useful OTC Drugs During a Disaster.”
Results: We developed our list of OTC drugs based on the following parameters: (1) while people with severe disorders (e.g. renal failure) are treated by medical teams, those with minor physical conditions are treated using OTC drugs and (2) those OTC drugs that can be used as substitutes for prescription drugs were preferably selected.  The List of Useful OTC Drugs ()—During a Disaster (containing 56 items) was developed for use mainly by medical professionals.  Further, pharmacists from disaster-relief medical teams may not always be available in disaster-stricken areas; therefore, the Information Card on Useful OTC Drugs During a Disaster was developed to enable disaster victims to independently make a certain level of decision.  The information card contained pictograms to call the attention of the disaster victims.
Conclusion: Our results can provide a common tool for drug suppliers, medical professionals engaging in relief works in disaster-stricken areas, and disaster victims.

Eosinophilic otitis media (EOM) shows a very high rate of association with asthma, and intractable otitis media involves marked eosinophil infiltration into the middle ear. The middle ear space is connected to the nasopharynx by the Eustachian tube, and it is considered a part of the upper respiratory tract. Allergic rhinitis and asthma often coexist as chronic inflammatory diseases of the upper and lower airways, respectively, and have an impact on each other. In fact, inhaled corticosteroids reduce seasonal eosinophilia systemically in the circulation and locally in the nasal mucosa, as well as attenuate seasonal nasal symptoms. We report a case of EOM associated with adult-onset asthma that improved following optimal asthma therapy after changing the treatment from inhaled fluticasone propionate (FP) (200 microg b.i.d.) to a combination of FP/salmeterol (250/50 microg b.i.d.). This result supports the hypothesis that EOM and asthma are closely linked, presenting as different manifestations of a similar disease syndrome.

  A 4–year trial of an undergraduate medical care education program for smoking cessation with the participation of simulated patients is described. Simulated medical care with the participation of simulated patients is thought to motivate medical students to learn clinical skills for smoking cessation. However, simulated medical care for smoking cessation is difficult to plan when both the medical students and the simulated patients are nonsmokers.

The prevalence of allergic diseases such as asthma, allergic rhinitis and atopic dermatitis has increased all over the world during the last two decades. Dietary change is supposed to be associated with this increase. If it is the case, an appropriate intake of foods or drinks with anti-allergic functions is expected to stop the increase. Flavonoids, ubiquitously present in vegetables, fruits or teas possess anti-allergic activities. Flavonoids inhibit histamine release, synthesis of IL-4 and IL-13 and CD40 ligand expression by basophils and mast cells. Analyses of structure-activity relationships of representative flavones showed that luteolin, apigenin and fisetin were the strongest inhibitors of IL-4 production with an IC₅₀ value of 2–5 μM and determined a fundamental structure for the inhibitory activity. Quercetin and kaempferol showed a substantial activity with an IC₅₀ value of 15–18 μM. The inhibitory activity of flavonoids on IL-4 and CD40 ligand expression were thought to be mediated through their inhibitory action on activation of nuclear factor of activated T cells and AP-1. Administration of flavonoids into atopic dermatitis-prone mice prevented the onset of dermatitis and serum IgE elevation and ameliorated the severity of dermatitis even after the onset. In addition a preliminary trial of flavonoids for adult patients with atopic dermatitis showed a significant effect. Recent epidemiological studies reported that a low incidence of asthma was significantly observed by population with a high intake of flavonoids. Thus, these evidences will be helpful for the development of low molecular compounds for allergic diseases and it is expected that an appropriate daily intake of flavonoids may be an effective complementary and alternative medicine and a preventative strategy for allergic diseases.

Objective : Carvedilol is a non-selective β blocker with an α blocking activity. Since this drug is highly fat-soluble, it can pass through the blood-brain barrier, and thus may induce depression and lower QOL. In the present study, physicians and pharmacists collaborated to evaluate the antihypertension effect of carvedilol and post-administration changes in QOL. Furthermore, the relationship between QOL and antihypertension effect was analyzed.
Design : Self-controlled study.
Patients and Methods : Subjects were outpatients with hypertension above the age of 70 years who visited one of 42 medical institutions in Japan between April 1995 and March 1996. A total of 243 patients were registered, and 10-20 mg of carvedilol was administered once a day for six months. Pharmacists assessed the QOL of these patients by asking 82 questions on three separate occasions : before administration and one and six months after administration. The antihypertensive effect of this drug was investigated in patients in whom all three QOL questionnaires were collected. The main test items were antihypertensive effect, changes in QOL (subjective QOL with a special emphasis on patient psychology), and the relationship between antihypertensive effect and QOL. The antihypertensive effect of this drug was statistically analyzed by a paired t-test, and changes in QOL were statistically analyzed using generalized estimating equations.
Results : All three QOL questionnaires were collected from a total of 146 patients. Their pre-administration systolic blood pressure was 159.6±1.4 mmHg, and diastolic blood pressure 94.0±0.9 mmHg, and their blood pressure decreased significantly one month after the start of administration. This antihypertensive effect of carvedilol persisted, and the systolic and diastolic blood pressure of these patients six months after the start of administration was 141.1±1.2 and 85.2±0.7 mmHg, respectively (significant decreases when compared to pre-administration levels ; both p<0.05).
Subjective QOL improved significantly after carvedilol administration. And, changes were not seen in sexual function. Changes in the five categories of subjective QOL were as follows : psychological stability, disease-induced inconvenience, and independence improved significantly after carvedilol administration, but changes were not seen in gratification or vitality. However, improvements in subjective QOL did not correlate with improvements in blood pressure.
Conclusions : The results of the present study showed that carvedilol improved QOL without negatively affecting sexual function. Subjective QOL reflects the psychological well-being of patients. In the present study, psychological stability, disease-induced inconvenience, and independence improved significantly, but changes were not seen in gratification or vitality. Since β blockers can suppress the central nervous system, they can reduce psychological stability, gratification and vitality. Even though carvedilol is highly fat-soluble, the results of non-clinical studies have shown that it does not suppress the central nervous system as much as propranolol. The results of the present study showed that carvedilol does not strongly suppress the central nervous system of humans. Moreover, significant changes in QOL were not seen between one and six months after the start of administration of carvedilol, suggesting that it is possible to estimate the QOL of patients on antihypertensive therapy after six months of administration by assessing their QOL one month after administration.

X type questions have been used for the national medical licensing examination since 1997. At Tsukuba University, X type questions have been used since 1996. We compared X typeand K type questions on the basis of the percentage of correct answers and discrimination power. The average percentage of correct answers was 68.2% for K type questions and 53.1% for X type questions. However, the average discrimination power was +0.227 for K type questions and +0.257 for X type questions. These results indicate that X type questions are more difficult and are suitable for achievement tests. The estimated knowledge quantity was 2.04 for K type questions and 2.32 for X type questions. This suggests that the person writing the questions decreased the essential difficulty of X type questions.

Phthalides and ligustilide in Senkyu extract and limonene and fravonoids in Chimpi extract have been reported to have strong vasodilation effects.
In the present study the circulatory effects of Senkyu and Chimpi extract (crude drug extract) were studied as bath agent in 40.0°C bath water (Senkyu ext. 224mg and Chimpi ext. 272mg/2001). Thirteen healthy men (36.2±5.8 years old) took a bath at 40.0°C for 10 min with and without (only with flavor and dye) crude drug extract and the circulatory effects were followed for 30 min after bathing.
Heart rate and cardiac output were increased equally by 10 min bathing either with or without crude drug extract. Although systolic blood pressure was slightly increased during bathing, diastolic blood pressure and total peripheral resistance were significantly decreased during and after bathing with and without crude drug extract. Forehead skin blood flow and sublingual temperature were significantly increased during bathing, and remained at higher level for 10-30 min after bathing with crude drug extract. Venous blood pO₂ and pH were significantly increased and pCO₂ was decreased equally with and without crude drug extract. Plasma NE was significantly increased by bathing with crude drug extract.
Bath agent with Senkyu and Chimpi extract are considered favorable as bath agent to keep high skin blood flow and sublingual temperature probably due to its vasodilating effects.
