Dysplastic nevus syndrome among Japanese. A case study and review of the Japanese literature.

Three Japanese families with dysplastic nevus syndrome (DNS) are reported. Each family had at least two members with multiple dysplastic nevi (DN). Family members with DN or multiple moles had paler skin than average Japanese, usually sunburned, and tanned less than average, whereas members with darker skin almost never had DN. Each of two families had one cutaneous malignant melanoma (CMM) patient associated with multiple DN. Both CMMs were on the leg. In Japanese DNS, skin color and sun sensitivity seem to be closely related to DN. The locations of CMMs associated with DNS were unique: No CMMs were found on acral areas where they most frequently occur in Japanese.

Validation of the Japanese version of the Roland-Morris Disability Questionnaire for Japanese patients with lumbar spinal diseases.

STUDY DESIGN: This study was designed to validate a translated version of the Roland-Morris Disability Questionnaire (RMDQ). OBJECTIVE: To validate the Japanese version of the RMDQ (JRMDQ) for Japanese patients with low back pain (LBP) and/or lumbar spinal diseases (LD). SUMMARY OF BACKGROUND DATA: To assess the effect of interventions, a scale that directly assesses disabilities in patients with LBP and/or LD and that can be used internationally needs to be established in Japan. MATERIALS AND METHODS: To promote the JRMDQ, the RMDQ was translated into Japanese and then back-translated. In four hospitals, 320 patients with LBP and/or LD were examined. At first, they were examined using the JRMDQ, the Japanese Orthopedic Association (JOA) score, and the visual analogue scale (VAS). The repeatability of the JRMDQ was evaluated in 55 patients by two examinations within 2 weeks. To examine the validity of the JRMDQ, the correlation between the JRMDQ and other scales was calculated in all 320 patients. RESULTS: The JRMDQ demonstrated significant repeatability (R = 0.810, P < 0.0001). The JRMDQ and other scales demonstrated significant correlations (JRMDQ-JOA, R = -0.772; JRMDQ-ADL items of JOA score, R = -0.790; JRMDQ-VAS, R = 0.447, P < 0.0001). CONCLUSIONS: The JRMDQ is a repeatable and valid questionnaire for assessing disabilities caused by LBP and/or LD. The JRMDQ is equivalent to the English RMDQ.

Identification of human T cell epitopes in Japanese cypress pollen allergen, Cha o 1, elucidates the intrinsic mechanism of cross-allergenicity between Cha o 1 and Cry j 1, the major allergen of Japanese cedar pollen, at the T cell level.

BACKGROUND: Pollens from species of Cupressaceae family are one of the most important causes of respiratory allergies worldwide. In Japan, many patients with pollinosis have specific IgE to both pollens of Japanese cypress (Chamaecyparis obtusa) and Japanese cedar (Cryptomeria japonica). The sequences between Cha o 1 and Cry j 1, the major allergens of Japanese cypress and Japanese cedar pollens, respectively, are 80% identical. OBJECTIVE: This study was undertaken to identify T cell epitopes in Cha o 1, and to elucidate the mechanism of cross-allergenicity between Cha o 1 and Cry j 1, at the T cell level. METHODS: T cell epitopes in Cha o 1 were identified by the reactivity of T cell lines, generated from 19 patients, to stimulation with overlapping peptides. The subsets of T cell clones specific to rCha o 1 were determined according to their ability to produce IL-4 and IFN-gamma. Peptide specificities of two T cell clones were determined by stimulation with the peptides from Cha o 1 and Cry j 1. RESULTS: Four dominant and six subdominant T cell epitopes were identified in Cha o 1. While four T cell epitopes, p11-30, p211-230, p251-270 and p331-350, were common to Cha o 1 and Cry j 1, 4 T cell epitopes, p61-80, p71-90, p311-330 and p321-340, were considered to be unique to Cha o 1. The subsets of T cell clones were predominantly of T helper2-type. One T cell clone recognized p16-30, which is common to Cha o 1 and Cry j 1, but another recognized p321-330, which is unique to Cha o 1. CONCLUSION: Presence of both T cells reactive to T cell epitopes common to Cha o 1 and Cry j 1 and T cells specific to T cell epitopes unique to Cha o 1 in patients with pollinosis contributes to prolonged symptoms after the cedar pollen season in March and the following cypress pollen season in April.

Genetic polymorphisms of bilirubin uridine diphosphate-glucuronosyltransferase gene in Japanese patients with Crigler-Najjar syndrome or Gilbert's syndrome as well as in healthy Japanese subjects.

BACKGROUND AND AIM: Numerous mutations of bilirubin uridine diphosphate-glucuronosyltransferase gene (UGT1A1) have been reported in patients with familial unconjugated hyperbilirubinemia. The UGT1A1 mutation appears to be considerably different among ethnic groups. To clarify the incidence of this gene mutation in the Japanese population, the presence of UGT1A1 mutation was investigated in a group of Japanese patients with Crigler-Najjar syndrome type 2 (CNS2) and Gilbert's syndrome (GS), as well as in healthy anicteric subjects. METHODS: Four patients with CNS2, 63 patients with GS, and 71 healthy subjects were enrolled in the study. The promoter and coding regions of UGT1A1 were amplified by polymerase chain reaction (PCR) from genomic DNA isolated from leukocytes. The PCR products were directly sequenced by a dye terminating method. The UGT1A1 enzyme activity was determined in COS7 cells transfected with wild or P364L (1091 C > T) mutant DNA. RESULTS: Homozygous Y486D was observed in all four patients with CNS2. The GS patients had UGT1A1 mutations with 13 different genotypes in the promoter and coding region. Homozygous TA insertion in the TATA box (TA7) of the promoter region (TA7/7; 33%), homozygous G71R (9%), and combination of TA7/6 and heterozygous G71R (17%) were the most frequent findings in GS patients. Homozygous or heterozygous Y486D (8%) and P229Q (8%) were also observed in GS. A novel mutation, heterozygous P364L, was also identified in a GS patient. In addition to GS patients, homozygous or heterozygous TA7, G71R, and heterozygous Y486D were also observed in healthy subjects. The allele frequency of G71R and TA7 was 0.183 and 0.113 in healthy subjects, respectively. The P364L UGT1A1 enzyme activity was 64.4% lower than the wild-type enzyme activity. CONCLUSIONS: Polymorphisms in the coding region of UGT1A1 were commonly observed in Japanese patients with GS and in healthy subjects. The genetic basis of hyperbilirubinemia appears to be different between the Japanese and Caucasian populations.

Relationship between age and drinking patterns and drinking problems among Japanese, Japanese-Americans, and Caucasians.

Comparing alcohol consumption patterns by age and gender among Japanese in Japan and Japanese-Americans and Caucasians in the United States, this study examined the associations between age and both heavy drinking and social problems using logistic regression for each ethnic group of male current drinkers. As reported in previous studies of Caucasians, men drink more alcohol than women, older respondents are more likely than younger ones to be abstainers, and the percentages of heavier drinkers and problem drinkers are higher among the young than among older people. Although Japanese-Americans reported consuming less alcohol than Caucasians, their drinking patterns by age were similar: among both United States populations, younger respondents are at higher risk for drinking problems than older respondents, even when alcohol consumption and sociodemographic variables are controlled by logistic regression. However, this association of age and drinking patterns and drinking problems is not universal. Japanese men consumed more alcohol and had a higher proportion of heavier drinkers in the middle age groups; the association between age and drinking problems also varied in this group. In addition to aging, sociocultural factors such as drinking norms probably account for the differences in drinking behavior among different age groups. This study may stimulate further cross-cultural comparison of drinking patterns and problems.

A strain-specific antigen in Japanese Helicobacter pylori recognized in sera of Japanese children.

An enzyme immuno assay (EIA) test based on Japanese strain-derived high-molecular-weight cell-associated proteins (JHM-CAP) was evaluated by comparing with a previously developed EIA test based on a U.S. strain-derived high-molecular-weight cell-associated proteins (HM-CAP). Serum samples of 131 Japanese asymptomatic children (mean age, 5.5 years; range, 0 to 21 years) were tested that include 43 positive and 88 negative children as judged by Helicobacter pylori stool antigen test (HpSA test). Both tests showed comparable and reliable specificities, but the sensitivity of JHM-CAP EIA, at 93.0%, was much higher than that of HM-CAP EIA, at 67.4%. More false-negative results of HM-CAP were obtained in children under 10 years of age. Immunoblot analysis revealed that the JHM-CAP but not the HM-CAP preparation had a 100-kDa antigen recognized by JHM-CAP positive sera. It was concluded that JHM-CAP EIA is highly accurate for the serodiagnosis of H. pylori infection in Japanese young children and that the high sensitivity of JHM-CAP EIA in contrast to HM-CAP EIA is due to the presence of a 100-kDa antigen in Japanese strains that may be recognized by the host immune system at an early stage of infection.

Nucleotide sequence of feline immunodeficiency virus: classification of Japanese isolates into two subtypes which are distinct from non-Japanese subtypes.

Seven isolates of feline immunodeficiency virus (FIV), Shizuoka, Yokohama, Sendai-1, Sendai-2, Fukuoka, Aomori-1, and Aomori-2, were isolated from FIV-seropositive domestic cats in Japan, and their proviral DNAs were amplified by PCR. The nucleotide sequences of their env and gag genes were determined and compared with those of previously described isolates: U.S. and European isolates and one Japanese isolate, TM2. Phylogenetic analyses of complete env gene sequences demonstrate that worldwide isolates are classified into three subtypes: Japanese TM2, Japanese Shizuoka, and non-Japanese subtypes (U.S. and European isolates), with 20% amino acid distances from each other. This pattern indicates that an evolutionary radiation of these three subtypes of FIV occurred at approximately the same time. The sequence data of gag genes also confirmed these results. Furthermore, the Sendai-1 isolate was identified as an imported FIV isolate.

Mutation of cytochrome P-45017 alpha gene (CYP17) in a Japanese patient previously reported as having glucocorticoid-responsive hyperaldosteronism: with a review of Japanese patients with mutations of CYP17.

A 17-yr-old female Japanese patient, who was reported in 1968 as having glucocorticoid-responsive hyperaldosteronism but was presumed to have a defect of 17 alpha-hydroxylation mainly in the adrenal glands as the etiology of her illness, was followed. The relationship between clinical manifestations and molecular abnormalities in cytochrome P-45017 alpha gene (CYP17) was also reviewed based on the literature on Japanese patients with 17 alpha-hydroxylase deficiency. She has been treated with dexamethasone, resulting in normal blood pressure and normokalemia for 28 yr. She had almost normal gonadal function with regular menstruation on her first admission. Because of sustained genital bleeding, however, she underwent total hysterectomy with an ovarian biopsy at the age of 42 yr. No follicles or corpus luteum were detected in the ovarian specimen. At the age of 45 yr, the basal levels of sex steroids were decreased, while those of gonadotropins were increased. A genetic study on CYP17 revealed a homozygous deletion of phenylalanine (Phe) codon (TTC) at either amino acid position 53 or 54 in exon 1. A review of the literature revealed 4 patients with this type of CYP17 mutation, including the present patient, out of a total of 11 young adult Japanese patients. The clinical manifestations caused by congenitally deficient gonadal function were not marked in any of these 4 patients, but were marked in 5 of the 7 patients with different mutations of CYP17. The remaining 2 female patients had irregular menstruation. The pretreatment urine/plasma values of aldosterone were variable, normal to high, in individual patients, regardless of the structural abnormalities of CYP17. The following conclusions were suggested: 1) this type of CYP17 mutation is associated with well preserved gonadal function in young adult patients, but it likely causes early reduction of gonadal function with increasing age in these patients; 2) the prevalence of this type of CYP17 mutation is quite high in Japanese patients; and 3) the pretreatment hyperaldosteronism observed in the present patient seems not to be related to the mutation of CYP17.

Gene screening of thyroxine-binding globulin (TBG) deficiencies in the Japanese: only two mutations account for TBG deficiencies in the Japanese.

T4-binding globulin (TBG) is the principal transport protein for thyroid hormone in the circulation. Twelve mutations in the human TBG gene have been reported, and the inheritance of those variant TBGs was shown to be X-chromosome linked. We previously reported a nucleotide deletion at the codon 352 (TBG-CDJ) and a nucleotide substitution at the codon 362 (TBG-PDJ) of the TBG gene in a Japanese male manifesting TBG complete deficiency and partial TBG deficiency, respectively. In this communication we investigate the prevalence of both mutations among 50 unrelated Japanese subjects manifesting complete or partial TBG deficiency from various areas of the Japanese Archipelago. Mutant alleles were identified by amplification of their genomic DNAs by PCR with allele-specific primers. In addition, the presence of a polymorphic mutation in codon 283 (TBG-Poly) in these variants was investigated. All male subjects manifesting complete TBG deficiency (n = 30) and all female subjects manifesting partial TBG deficiency (n = 4) were demonstrated to be hemizygotes and heterozygotes for the mutation of TBG-CDJ, respectively. All male subjects manifesting partial TBG deficiency (n = 16) were shown to have the mutation of TBG-PDJ as hemizygotes. TBG-Poly was consistently absent from these variants. We conclude that only TBG-CDJ and TBG-PDJ may account for complete and partial TBG deficiencies in the Japanese.

Molecular phylogeny of Japanese Leporidae, the Amami rabbit Pentalagus furnessi, the Japanese hare Lepus brachyurus, and the mountain hare Lepus timidus, inferred from mitochondrial DNA sequences.

We determined mitochondrial 12S ribosomal RNA (rRNA) and cytochrome b (cyt b) gene sequences in three leporid species of Japan, the Amami rabbit Pentalagus furnessi from the Ryukyu Islands, the Japanese hare Lepus brachyurus from Honshu, and a Japanese form of the mountain hare Lepus timidus ainu from Hokkaido. We compared the sequences with those of other taxa of leporids available in databases. Phylogenetic trees of the 12S rRNA gene sequences indicated that the lineage of P. furnessi diversified during the generic radiation of the leporids at an ancient time, which was estimated to have been the middle Miocene. Cyt-b gene trees revealed that the lineage of L. brachyurus branched off at an early stage in the speciation of Lepus, probably at the beginning of the Pliocene. The cyt b sequences of L. t. ainu were somewhat distinct from those of continental conspecific populations; this lineage divergence is likely to have occurred during the middle or late Pleistocene. The results show that the three regions of the Japanese archipelago, Ryukyu, Honshu-Shikoku-Kyushu, and Hokkaido, now preserve their own leporid taxa, each with a different extent of genetic endemicity. It is possible that the zoogeographic traits of the Japanese leporids are a consequence of the evolutionary dynamics of leporids in East Asia, in that the radiation centers of leporids are likely to have shifted from tropical, through temperate, to arctic zones.

Validity and reliability of the Japanese version of the selected anger expression scale and age, sex, occupation and regional differences in anger expression among Japanese.

To examine the reliability and construct validity of the Japanese version of the Anger Expression Scale among four Japanese communities, and to examine distributions of anger expression scores according to sex, age, occupation, and community, we performed a cross-sectional study among 1,802 men and 3,229 women aged 20-70 in four geographic populations in 1995-97. We handed a self-administered questionnaire, which was selected from the Spielberger Anger Expression Scale, to the participants in the risk factor surveys and measured anger-in and anger-out as the anger expression scale. These scales had high internal consistency (Cronbach's alpha coefficient was 0.97-0.98 for anger-out and 0.77-0.86 for anger-in) and were of almost the same structure as the original. The Pearson correlation coefficients for the anger expression scale examined in 1995 and 1996 were 0.69 for anger-out and 0.57 for anger-in (both p < 0.001). The mean scores of both anger-out and anger-in were inversely associated with age. The mean anger-out score was higher for men than for women (p < 0.001), whereas the mean anger-in score did not vary significantly between the sexes. Furthermore, the mean scores of anger-out and anger-in varied among populations and occupational groups. The present study suggests that the Japanese version of the selected Anger Expression Scale is an acceptable scale for evaluating anger expression among Japanese.

Japanese alcoholic beverage and all cause mortality in Japanese adult men.

This article examines whether an association is found between quantity of alcohol consumed and all cause mortality, and a relation is detected between types of alcoholic beverage and all cause mortality in Japanese male adults. A cohort study was performed in three towns located in two former coal mine areas and a rural area in Fukuoka. A mail survey was carried out between 1988 and 1990, and was extended in a follow-up period to 1995 (two towns) and 1999 (one town). 6,652 Japanese men aged from 40 to 69 years responded to a questionnaire that included alcohol consumption and smoking habit. The data were analysed with Cox's proportional hazards model. As regards an association between all cause mortality and quantity of alcohol consumed, statistically significant relations were recognized in occasional drinkers and drinkers with less than 25g ethanol per day (hazard ratio= 0.71, 95% CI: 0.50-0.99; hazard ratio= 0.51, 95% CI: 0.29-0.88, respectively). With respect to drinkers with 25-50g/day and > or =50g/day, no significant relation was observed in the risk for all cause mortality. Comparing all cause mortality for daily drinkers and nondrinkers with respect to the beverage types, a risk was lower for daily drinkers than for nondrinkers with every type of beverage studied. In particular, there was a statistically significant adverse association for all cause mortality among subjects who reported drinking Japanese sake compared with nondrinkers (hazard ratio= 0.45, 95% CI: 0.30-0.68). Alcohol consumption (particularly Japanese sake) is likely to be associated with a reduced hazardous ratio of all cause mortality.

Values of water-soluble vitamins in blood and urine of Japanese young men and women consuming a semi-purified diet based on the Japanese Dietary Reference Intakes.

We investigated the levels of water-soluble vitamins except for vitamin B6 in the blood and urine of Japanese college male (n = 10) and female (n = 10) students. They consumed for 7 d a semi-purified diet based on Japanese Dietary Reference Intakes to assess the Recommended Dietary Allowances (RDA) for water-soluble vitamins and to present some new normal values for blood and urine levels of water-soluble vitamins in Japanese. The blood and the 24-h urine samples were collected on the last day of the experiment and measured. The values of total vitamin B1 in whole blood, total vitamin B2 in whole blood, total cyanocobalamin in serum, total nicotinamide in whole blood, total pantothenic acid in whole blood, total folates in serum, total biotin in serum, and ascorbic acid in plasma were 104+/-17 pmol/mL (mean+/-SD), 216+/-25 pmol/mL, 0.34+/-0.05 pmol/mL, 59.1+/- 5.0 nmol/ mL, 2.45+/-0.37 nmol/mL, 15.6+/-4.6 pmol/mL, 8.3+/-0.5 pmol/mL, and 62+/-10 nmol/mL, respectively, in males, and 90+/-23, 234+/-18, 0.67+/-0.20, 61.9+/-6.0, 2.48+/-0.30, 30.2+/-8.6, 8.4+/-0.3, and 67+/-14, respectively, in females. There was a significant difference in the values of cyanocobalamin and total folates between men and women. The urinary excretion of vitamin B1, vitamin B2, cyanocobalamin, sum of the catabolic metabolites of nicotinamide, pantothenic acid, folates, biotin, and ascorbic acid were 665+/-114 nmol/d, 562+/-325 nmol/d, 93+/-31 pmol/d, 84+/-26 micromol/d, 9.3+/-2.3 micromol/d, 19.4+/-2.8 nmol/d, 83+/-18 pmol/d, and 148+/-51 micromol/d, respectively, in males, and 495+/-212, 580+/-146, 145+/-49, 83+/-19, 16.9+/-1.3, 22.7+/-2.7, 83+/-23, and 140+/-51, respectively, in females. There was a significant difference in the urinary excretion of cyanocobalamin, pantothenic acid and total folates between men and women. These values will be useful for the nutritional assessment of water-soluble vitamins for Japanese, although the examination period was short. In future, an experiment with various age groups and re-evaluation by repeated experiments will provide more accurate values.

Performance of Japanese and Japanese-American children on the Motor Accuracy-Revised and Design Copying Tests of the Southern California Sensory Integration Tests.

This study investigates whether cultural differences affect childrens' performances on the Design Copying (DC) and Motor Accuracy-Revised (MAC-R) Tests of the Southern California Sensory Integration Tests. The DC and the MAC-R were administered to 98 children who were born in Japan and lived there at least during the first year of life and to 82 children who were of Japanese descent but who were born in America. Average test scores of the Japanese and Japanese-American children were compared with those of the American children, on whom the tests were standardized. Results of the tests requiring right-hand performance revealed that both groups of Japanese-descent children performed better than the standardization group of American children; the Japan-born children performed the best. We base these findings on the influence that culture has on the development of a child.

Clinical investigation: Reliability and validity of the Japanese version of quality of life radiation therapy instrument (QOL-RTI) for Japanese patients with head and neck malignancies.

PURPOSE: To evaluate the reliability and validity of the Japanese translation of Quality of Life Radiation Therapy Instrument (QOL-RTI) and the head and neck module (H&N) for Japanese patients being treated with radiotherapy for head and neck malignancies. MATERIALS & METHODS: The QOL-RTI/H&N was translated into Japanese by a preliminary QOL research working group of JASTRO and was used in this clinical trial. From 1998 to 2001, 70 patients with head and neck malignancies for whom radical radiotherapy was planned were entered into this study. Patients were requested to answer the questions before radiotherapy at baseline, twice during week 4 of therapy (for test-retest reliability), at the end of treatment, and 3 months, 6 months, 1 year and 2 years from the beginning of radiotherapy. Internal consistency was assessed by Cronbach's alpha coefficient. Validity was assessed by comparing the results with EORTC-QLQ-C30 and with QOL questionnaire for cancer patients treated with anticancer drugs (QOL-ADC). Patient compliance and test sensitivity were also analyzed. RESULTS: Cronbach's alpha coefficient was 0.79 to 0.93 depending on the time point for the evaluation. Test-retest reliability was acceptable, with a Pearson coefficient of 0.83 for QOL-RTI and 0.92 for H&N module. Compliance with this scheme was 98.2%. The QOL-RTI was sensitive enough to detect significant changes in the QOL score during and after the course of radiotherapy. Agreement with the EORTC-C30 was good with a high Pearson correlation coefficient of 0.648 and that with QOL-ADC was also good with a coefficient of 0.566. The factors analyzed consisted of 11 functional/health-oriented questions, 5 emotional/ psychological, 5 socio-economic/ family and 2 general. CONCLUSION: The Japanese version of QOL-RTI with H&N module was found to be reliable and sensitive enough to evaluate variation of QOL in patients with head and neck malignancies during and after radiotherapy.

Mitochondrial DNA variation in the Japanese marten Martes melampus and Japanese sable, Martes zibellina.

Genetic relationship among Japanese sables, Martes zibellina and the introduced Japanese martens, Martes melampus in northern Japan was revealed by analyzing a 521-524bp DNA sequence from the cytochrome b (112bp)/transfer RNA-threonine (67bp)/tRNA-proline (65bp) and control region (277-280bp) of the mitochondrial genome. Intraspecific differences in sequences of M. zibellina and M. melampus (3.8-15.0% and 1.9-16.4%, respectively) were similar to interspecific differences between these two species (5.8-16.6%). Comparison of sequence data exhibited five haplotypes of M. melampus and four haplotypes of M. zibellina, which clustered into two groups (clusters-A and-B). Cluster-A included two haplotypes of M. melampus and two haplotypes of M. zibellina, whereas cluster-B included three haplotypes of M. melampus and two haplotypes of M. zibellina. Results of this study lead three possible explanations. Firstly, past hybridization between M. zibellina and M. melampus might have occurred. Secondary, these two species might have similar heteroplasmy of mtDNA. Thirdly, these haplotypes might have come from nuclear genome. Although further intensive studies are needed to make a conclusion, detection of hybridization with the Japanese marten are occurred or not is quite important to conserve the Japanese sable.

[Quality of life in patients with Japanese cedar pollinosis: using the SF-8 health status questionnaire (Japanese version)].

BACKGROUND: The number of patients with Japanese cedar pollinosis (JCP) is increasing, and now, has extended up to about 15% of the Japanese. It is reported that the QOL is an important outcome in the JCP treatment. This study aimed to evaluate the QOL in patients with JCP by means of the SF-8 Health Survey (Japanese Version), a new, even shorter generic health survey. METHODS: 411 patients with JCP who visited 10 ENT clinics in Osaka from March 14 to March 26 (peak pollen season) were questioned, and 204 patients without any treatments in this season were engaged in this study as subjects. In this study, the QOL scores were evaluated using the SF-8. This is an 8-item version of the SF-36 that yields a comparable 8-dimension health profile and comparable estimates of summary scores for the physical and mental components of health. RESULTS: The QOL score depressed in the patients with JCP compared with healthy subjects (Japanese national norms). Both Mental Component Score (MCS) and Physical Component Score (PCS) scores decreased more in females than in males. In females, MCS were significantly lower than national norms. The older the patients were, the lower PCS scores were showed. The severity of nasal symptoms influenced the PCS scores. CONCLUSION: These results showed the tendency similar to the early studies using SF-36 questionnaire. The sensitivity of SF-8 in the individual is not better than that of other specific QOL questionnaires, but SF-8 can be answered in a short time compared with other questionnaires including SF-36. We suggested that SF-8 become a useful questionnaire in the future.

Japanese age-related macular degeneration trial: 1-year results of photodynamic therapy with verteporfin in Japanese patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration.

PURPOSE: To determine the effect and safety of verteporfin therapy (Visudyne) in Japanese age-related macular degeneration (AMD) patients. DESIGN: Open-label, multicenter, prospective, noncontrolled study. METHODS: The setting was five university hospitals in Japan. The study population was patients at least 50 years old, with best-corrected visual acuity of 20/40 to 20/200 inclusive and fluorescein angiography documenting subfoveal, classic-containing choroidal neovascularization (CNV) secondary to AMD and a lesion of greatest linear dimension <or= 5400 microm. For the intervention, patients received verteporfin intravenously followed by light administration 15 minutes after the infusion start. Additional treatment was given every 3 months through month 9 if leakage from CNV was observed on angiogram. The main outcome measure was percentage of lesions with progression of classic CNV beyond the area of the baseline lesion. RESULTS: Sixty-four patients were enrolled at five centers, and 61 patients completed the study. The median number of treatments given during the trial was three. At the 12-month examination, 12 patients (19%; 95% confidence interval: 11%-31%) had progression of classic CNV whereas 32 (50%) and 49 (77%) patients had no leakage from classic or occult CNV, respectively. The median visual acuity score (approximate Snellen equivalent) from baseline to month 12 increased from 50.0 (20/100)-56.5 (20/80(+2)) letters. Fourteen patients (22%) had visual disturbances, including two patients (3%) with acute vision decrease considered as serious adverse events and one patient (2%) with infusion-related back pain. No photosensitivity reactions were reported. CONCLUSIONS: Verteporfin therapy for subfoveal CNV in these Japanese patients appeared to have a similar or better angiographic and vision effect as that observed in Caucasian patients, with the same safety profile, supporting its use in Japanese patients.
