Characterization of familial Waldenstrom's macroglobulinemia.

BACKGROUND: Familial clustering of B-cell disorders among Waldenström's macroglobulinemia (WM) patients has been reported, though the frequency and any differences in disease manifestation for familial patients remain to be defined. PATIENTS AND METHODS: We therefore analyzed clinicopathological data from 257 consecutive and unrelated WM patients. Forty-eight (18.7%) patients had at least one first-degree relative with either WM (n = 13, 5.1%), or another B-cell disorder including non-Hodgkin's lymphoma (n = 9, 3.5%), myeloma (n = 8, 3.1%), chronic lymphocytic leukemia (n = 7, 2.7%), monoclonal gammopathy of unknown significance (n = 5, 1.9%), acute lymphocytic leukemia (n = 3, 1.2%) and Hodgkin's disease (n = 3, 1.2%). Patients with a familial history of WM or a plasma cell disorder (PCD) were diagnosed at a younger age and with greater bone marrow involvement. RESULTS: Deletions in 6q represented the only recurrent structural chromosomal abnormality and were found in 13% of patients, all non-familial cases. Interphase FISH analysis demonstrated deletions in 6q21-22.1 in nearly half of patients, irrespective of familial background. CONCLUSIONS: The above results suggest a high degree of clustering for B-cell disorders among first-degree relatives of patients with WM, along with distinct clinical features at presentation based on familial disease cluster patterns. Genomic studies to delineate genetic predisposition to WM are underway.

In vivo organ mass of Korean adults obtained from whole-body magnetic resonance data.

In vivo organ mass of the Korean adult, male and female were presented for the purpose of radiation protection. A total of 121 healthy volunteers (66 males and 55 females), whose body dimensions were close to that of average Korean adults, were recruited for this study. Whole-body magnetic resonance (MR) images were obtained, and contours of 15 organs (brain, eye, gall bladder, heart, kidney, liver, lung, pancreas, stomach, spleen, testes, thymus, thyroid, urinary bladder and uterus) and 9 bones (femur, tibia + fibula, humerus, radius + ulna, pelvis, cervical spine, thoracic and lumber spine, skull and clavicle) were segmented for organ volume rendering by anatomists using commercial software. Organ and bone masses were calculated by multiplying the Asian reference densities of the corresponding organs and bones by the measured volumes. The resulting organ and bone masses were compared with those of the International Commission of Radiological Protection (ICRP) and the Asian reference data. Significantly large standard deviation was shown in the moving organs of the respiratory and circulatory systems and in the alimentary and urogenital organs that are variable in volume in a single person. Gall bladder and pancreas showed unique Korean organ masses compared with those of ICRP and the Asian reference adults. Different from anatomical data based on autopsy, the in vivo volume and mass in this study can more exactly describe the organ volume of a living human subject for radiation protection. A larger sample size would be required for obtaining statistically more reliable results. It is also needed to establish the reference organ mass of younger age groups for which it is difficult to recruit volunteers and to immobilise the subjects for long-time MR scanning. At present, the data from this study will contribute to the establishment of a Korean reference database.

Disease damage and low bone mineral density: an analysis of women with systemic lupus erythematosus ever and never receiving corticosteroids.

OBJECTIVES: To evaluate the relationship between disease damage and bone mineral density (BMD) in women with systemic lupus erythematosus (SLE). METHODS: A cross-sectional study was conducted among 307 women with SLE. Patients attended a single clinic visit that included an interview, physical examination, laboratory testing and BMD measurements (hip and/or lumbar spine). Women were stratified by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology cumulative disease damage index (SDI) > or =1 (Damage) vs SDI=0 (No Damage), and prior use of corticosteroids (CS), yielding four groups: (1) Damage/CS(+) (n=138), (2) Damage/CS(-) (n=23), (3) no Damage/CS(-) (n=100), and (4) no Damage/CS(-) (n=46). RESULTS: Mean age at SLE diagnosis was 32.7 +/- 11.8 yr, 24.4% were African American, 65.0% were premenopausal, and mean SDI +/- S.D. was 1.3 +/- 1.8. In the unadjusted and adjusted models controlling for significant univariate risk factors for osteoporosis, the reference group (Group 1) had significantly lower mean BMD T-scores at the hip and lumbar spine than groups having no disease damage (Groups 3 and 4) independent of CS use status. Similar hip and lumbar spine mean BMD T-scores were observed in women with disease damage with and without CS exposure (Groups 1 and 2). CONCLUSIONS: Women with SLE having disease damage and no CS use had BMD T-scores at the hip and lumbar spine similar to those of women with disease damage and prior CS use. These findings suggest an association between disease damage and lower BMD T-scores in women with SLE.

Interaction analysis between 5-HTTLPR and TNFA -238/-308 polymorphisms in schizophrenia.

This study investigated the potential interaction between the polymorphisms of serotonin transporter gene (SLC6A4, a 44 base pair insertion/deletion in the promoter region, 5-HTTLPR) and tumor necrosis factor-alpha gene (TNFA; -238G/A and -308G/A polymorphisms) on the development of schizophrenia, as well as the interaction of the three polymorphisms in relation to symptomatology, family history, onset age and antipsychotic treatment response. Genomic DNA analyses with polymerase chain reaction (PCR) was used for the genotyping. One hundred and fifty-two (152) patients with schizophrenia and 152 normal controls participated in the study. Any associations between the individual polymorphism and schizophrenia were not found. However, marginal association between subjects with both TNFA -238 A allele (genotype AA plus AG) and 5-HTTLPR s allele (ss plus sl) and presence of family history was found (p = 0.023; p = 0.026). The subjects with TNFA -308 AG genotype showed higher change in PANSS total score (p = 0.028). No significant interaction effect between 5-HTTLPR and TNFA -238/-308 polymorphisms either on the development of schizophrenia or on antipsychotics treatment response and psychopathology was found, although a significant interaction effect for subjects carrying TNFA -238 AG and -308 AA genotypes on a positive family history was observed (p = 0.017). These results suggest that the interaction effects between 5-HTTLPR and TNFA -238/-308 polymorphisms gives no significant contribution to the susceptibility to schizophrenia, and is not associated with clinical variables, antipsychotic treatment response and psychopathological features, except for family history of disease, at least in the Korean population.

Nitric oxide stimulates a large-conductance Ca-activated K+ channel in human skin fibroblasts through protein kinase G pathway.

In order to investigate the large-conductance Ca(2+)-activated K(+) (BK(Ca)) channel and determine the effects of nitric oxide (NO) on the channel in human skin fibroblasts, we performed electrophysiological patch clamp recordings on 5th-passage cells of human genital skin cultures. The whole-cell outward K(+) current was increased with depolarization, and proved to be sensitive to NS1619 (a selective BK(Ca) channel activator) and iberiotoxin (a specific BK(Ca )channel inhibitor). The single-channel currents showed 226 pS of mean conductance in symmetrical K(+). Sodium nitroprusside (SNP; an NO donor) significantly increased the K(+) current amplitude in the whole-cell mode, and open probability of the channel (NPo) in the cell-attached mode, but not in the inside-out mode. S-nitroso-N-acetylpenicillamine (an NO donor) and 8-Br-cGMP (a membrane-permeant cGMP analogue) also increased the BK(Ca )channel activity. The stimulatory effect of SNP on BK(Ca) channels was inhibited by pretreatment with 1H-[1,2,4]-oxadiazolo[4,3-a]quinoxalin-1-one (a soluble guanylyl cyclase inhibitor), or KT5823 [a specific protein kinase G (PKG) inhibitor]. Cytoplasmic PKG also increased the channel activity in inside-out patches. In conclusion, the present data indicate that BK(Ca) channels constitute a significant fraction of K(+) current in human skin fibroblasts, and that NO increases NPo of BK(Ca) channels, which are mediated via the cGMP/PKG pathway, without direct effects on the channel.

Genetic analysis and conservation of the endangered Canary Island woody sow-thistle, Sonchus gandogeri (Asteraceae).

Sonchus gandogeri, a woody sow-thistle, is an endangered Canary Island endemic with only two known populations, one in the El Golfo and another in the Las Esperillas of El Hierro. Amplified fragment length polymorphism (AFLP) markers were used to assess the genetic variation within and among populations. The mean genetic diversity of two populations was estimated to be 0.380, and the El Golfo population (0.380) had higher genetic diversity than the southeastern one (0.268). The unbiased Nei's genetic identity between the two populations was 0.846. The mean genetic diversity of S. gandogeri was much higher than that of the other endangered plant species. This is perhaps due to breeding system, life form, extinction, and/or introgressive hybridization and hybrid origin of the taxon. This study also indicates that the two populations are not strongly differentiated (G(ST)=0.149). This study suggests that S. gandogeri is more likely to become extinct due to environmental or demographic forces than genetic factors, such as inbreeding depression. More strict control of introduced herbivores is necessary to protect these populations, and germplasm collection for ex situ conservation is needed.

Selection bias in quantitative trait loci mapping.

A simulation study was performed to see whether selection affected quantitative trait loci (QTL) mapping. Populations under random selection, under selection among full-sib families, and under selection within a full-sib family were simulated each with heritability of 0.3, 0.5, and 0.7. They were analyzed with the marker spacing of 10 cM and 20 cM. The accuracy for QTL detection decreased for the populations under selection within full-sib family. Estimates of QTL effects and positions differed (P < .05) from their input values. The problems could be ignored when mapping a QTL for the populations under selection among full-sib families. A large heritability helped reduction of such problems. When the animals were selected within a full-sib family, the QTL was detected for the populations with heritability of 0.5 or larger using the marker spacing of 10 cM, and with heritability of 0.7 using the marker spacing of 20 cM. This study implied that when selection was introduced, the accuracy for QTL detection decreased and the estimates of QTL effects were biased. A caution was warranted on the decision of data (including selected animals to be genotyped) for QTL mapping.

Chinese herbal medicine for atopic eczema.

BACKGROUND: Traditional Chinese herbal mixtures have been used to treat atopic eczema for many years. Their efficacy has attracted public attention and recently some clinical trials have been undertaken. OBJECTIVES: To assess the effects of Chinese herbal mixtures in the treatment of atopic eczema. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) ( January 2004), the Cochrane Skin Group Specialised Register (January 2004), MEDLINE (1966 to January 2004), EMBASE (1980 to January 2004), CINHL (1980 to January 2004) and a number of complementary medicine databases. In addition, the cited references of all trials identified and key review articles were searched. Pharmaceutical companies involved in oral traditional Chinese herbs and experts in the field were contacted. SELECTION CRITERIA: Randomised controlled trials of Chinese herbal mixtures used in the treatment of atopic eczema. DATA COLLECTION AND ANALYSIS: Two reviewers independently applied eligibility criteria, assessed the quality of the trials and extracted data. Any discrepancies were discussed to achieve consensus. MAIN RESULTS: Four randomised controlled trials, with eight weeks for each phase, met the inclusion criteria. The trials randomised 159 participants aged from 1 to 60 years. The withdrawal rates ranged from 7.5% to 22.5% and no trial used intention to treat analysis. Three trials were randomised placebo controlled, two-phase cross-over designs assessing the same Chinese herbal mixture, Zemaphyte. In two of these three trials the reduction in erythema and surface damage was greater on Zemaphyte than on placebo, and participants slept better and expressed a preference for Zemaphyte. One trial also reported that participants itched less. The fourth trial was an open-label design comparing Zemaphyte in herbal form with Zemaphyte as a freeze dried preparation. There was a reduction in erythema and surface damage with both formulations, but no comparison between the two formulations was reported. Some adverse effects were reported in all four trials, but none were regarded as serious. AUTHORS' CONCLUSIONS: Chinese herbal mixtures may be effective in the treatment of atopic eczema. However, only four small poorly reported RCTs of the same product, Zemaphyte, were found and the results were heterogeneous. Further well-designed, larger scale trials are required, but Zemaphyte is no longer being manufactured.

Congenital diaphragmatic hernia and chromosome 15q26: determination of a candidate region by use of fluorescent in situ hybridization and array-based comparative genomic hybridization.

Congenital diaphragmatic hernia (CDH) has an incidence of 1 in 3,000 births and a high mortality rate (33%-58%). Multifactorial inheritance, teratogenic agents, and genetic abnormalities have all been suggested as possible etiologic factors. To define candidate regions for CDH, we analyzed cytogenetic data collected on 200 CDH cases, of which 7% and 5% showed numerical and structural abnormalities, respectively. This study focused on the most frequent structural anomaly found: a deletion on chromosome 15q. We analyzed material from three of our patients and from four previously published patients with CDH and a 15q deletion. By using array-based comparative genomic hybridization and fluorescent in situ hybridization to determine the boundaries of the deletions and by including data from two individuals with terminal 15q deletions but without CDH, we were able to exclude a substantial portion of the telomeric region from the genetic etiology of this disorder. Moreover, one patient with CDH harbored a small interstitial deletion. Together, these findings allowed us to define a minimal deletion region of approximately 5 Mb at chromosome 15q26.1-26.2. The region contains four known genes, of which two--NR2F2 and CHD2--are particularly intriguing gene candidates for CDH.

Abeta vaccination effects on plaque pathology in the absence of encephalitis in Alzheimer disease.

The authors report a patient with Alzheimer disease (AD) without encephalitis who was immunized with AN-1792 (an adjuvanted formulation of Abeta-42). There were no amyloid plaques in the frontal cortex and abundant Abeta-immunoreactive macrophages, but tangles and amyloid angiopathy were present. The white matter appeared normal and minimal lymphocytic infiltration in the leptomeninges was observed. This case illustrates the effects of an Abeta-based immunization on AD pathogenesis in the absence of overt meningoencephalitis and leukoencephalopathy.

Factors influencing the success of conservative treatment of interstitial pregnancy.

OBJECTIVE: To identify demographic, morphological and biochemical characteristics of interstitial pregnancies that are associated with a successful outcome of conservative treatment (expectant management or medical treatment with methotrexate). METHODS: Over a period of 6 years all clinically stable women with a certain ultrasound diagnosis of interstitial ectopic pregnancy were managed either expectantly (no interventions) or medically (systemic or local methotrexate injection). The outcome of conservative treatment was compared to a number of diagnostic parameters, which were recorded at the initial visit. The treatment was classified as successful if serum human chorionic gonadotropin (hCG) level declined below 20 IU/L without the need for any additional interventions, such as the administration of methotrexate or surgery. RESULTS: A total of 42 interstitial pregnancies were diagnosed during the study period. Out of 35 women included in the final analysis 7 (20%) were managed expectantly and 28 (80%) received either local (n = 23) or systemic methotrexate (n = 5). There were no significant differences in the success rates of expectant treatment and treatment with either systemic or local methotrexate. The initial median serum hCG was significantly lower in women with successful conservative management (3216 IU/L vs. 15 900 IU/L; P < 0.05) but there were no other significant differences between cases with successful and failed treatment. CONCLUSION: The measurement of serum hCG at the initial visit may be used to predict the likelihood of successful conservative treatment of interstitial pregnancy.

[Subjective developmental outcome in bladder exstrophy and epispadias. A pilot study].

The bladder exstrophy-epispadias complex (BEEC) belongs to one of the most devastating urological malformations affecting the complete urinary tract including the genitalia. A semi-standardized questionnaire was used to evaluate the functional and psychosocial developmental outcome in 122 affected patients recruited from German-speaking self-referral support groups. The questionnaire covered mode of reconstruction, subjective assessment of continence, milestones of child development, education, school performance, level of life satisfaction, anxieties, and in patients older than 16 years partnership experience. The results showed a mean of one surgery in the age group 0-4, of four surgeries in both age groups 5-13 and 14-20, and seven surgeries in patients aged 20 and over. The continence rates for the latter three age groups were 36, 64, and 80%, respectively. We found that the neurocognitive development was unremarkable. Most patients showed above average performance in school and in their profession. On the other hand, they exhibited psychological anxieties and worries in their experience with sexuality and partnerships. Future studies will be necessary to clarify the association of urological status, functional impairments, and psychosocial adaptation as a basis for improved approaches to comprehensive care and support.

Clinical features and surgical management of retinal detachment secondary to round retinal holes.

AIMS: The majority of rhegmatogenous retinal detachments result from pathological posterior vitreous detachment (PVD) and secondary horseshoe or giant retinal tears. Retinal detachment without PVD is usually associated with either retinal dialysis or round retinal holes. This study characterises the features, surgical outcome, and incidence of bilateral involvement of detachment associated with round retinal holes. METHODS: In all, 110 retinal detachments from 96 consecutive patients with retinal detachment secondary to round retinal holes were studied. Analysis of patient age, sex, refraction, preoperative visual acuity, presented symptoms, position and extent of detachment, number and distribution of holes present, posterior hyaloid membrane status, surgical management, outcome of surgery, and postoperative visual acuity were studied. RESULTS: The mean age for patients was 34 years with a marked female preponderance (64%) and myopia (83%). The posterior hyaloid membrane remained attached in 95 eyes (86%). In all, 45% patients had bilateral pathology, of which 33% had 'mirror image' distribution. Detachments were predominantly shallow (93%) and slow in progression (17%). A total of 100 detachments were repaired with cryotherapy and scleral buckling, eight with cryotherapy alone, and one with laser retinopexy. In all, 99% detachments were successfully reattached with a single procedure. The mean follow-up period was 2 years. There were no instances of redetachment. CONCLUSIONS: Round hole detachments are slowly evolving detachments with attached vitreous gel in young, predominantly female myopes. Examination of the fellow eye should be mandatory as there is a high incidence of bilateral pathology. Scleral buckling procedures remained highly effective in this selected group of patients.

A comparison between prophylaxis and on demand treatment for severe haemophilia.

Patients with severe haemophilia can be treated for bleeding either prophylactically or on demand. Each treatment modality has advantages and disadvantages from both a medical and economic point of view. This study aims to find which modality requires more units of clotting factors per body weight per year and to compare the number of bleeds between the two. The study sample consisted of 133 patients with severe haemophilia A and B treated in the Katharine Dormandy Haemophilia Centre at the Royal Free Hampstead NHS Trust in London. The average number of clotting factors used per body weight per year was 2181.7 units for prophylaxis vs. 711 units for on demand treatment (P = 0.000). Although more units used means more money spent, and although prophylaxis has additional complications, namely venipunctures and increased risk of viral contamination, other criteria must be considered including the total number of bleeds and health-related quality of life. The total number of bleeds per year was significantly (P = 0.021) less for prophylactically (7.4) vs. on-demand treated patients (11.4). This suggests that prophylaxis reduces the risk of arthropathies, the number of future hospital visits and orthopaedic surgeries, and is thus the optimal modality of treatment for patients with severe haemophilia.

An exploration of health-related quality of life in adults with haemophilia--a qualitative perspective.

Musculoskeletal dysfunction is a common feature of haemophilia and along with other manifestations of this condition, there is a general perception that health-related quality of life (QoL) will be affected. Previous research using standardized questionnaires has demonstrated that QoL is lower in haemophilia groups compared with normal populations. However, disability studies and interviews with disabled people suggest that many disabled people experience positive life changes as a result of their illness and an affirmative model of disability has been proposed. A qualitative study involving focus groups and interviews was undertaken to explore these issues in a group of 19 severely affected adults with haemophilia. The focus groups and interviews were tape recorded and fully transcribed and the results subjected to thematic analysis. This paper focuses specifically on key issues that impacted on perceptions of QoL. The findings suggest that the participants' perceptions of their QoL were very positive. Possible reasons for this are proposed including the benefits of factor replacement, participants' recollections of their lifestyle before factor replacement, that having haemophilia was integral to the 'self' and finding a niche where they could be successful. A more positive affirmation of haemophilia may need to be considered when developing QoL measures.

The simultaneous detection of both enteroviruses and adenoviruses in environmental water samples including tap water with an integrated cell culture-multiplex-nested PCR procedure.

AIMS: To evaluate an integrated cell culture (ICC)-multiplex-nested PCR using the buffalo green monkey kidney (BGMK) cells for the simultaneous detection of both enteroviruses and adenoviruses in surface water and tap water samples and optimize the procedure for more sensitive detection of virus showing no apparent cytopathic effect (CPE). METHODS AND RESULTS: A total of 69 surface water and 50 tap water samples were analysed by the ICC-multiplex-nested PCR. All the PCRs were performed five times with a cell lysate from each flask after at least 2 weeks incubation. Forty-six surface water samples (66.7%) and 23 tap water samples (46.0%) exhibited CPE by the cell culture method. By using an ICC-multiplex-nested PCR, 53 surface water samples (76.8%) and 29 tap water samples (58.0%) were determined as containing infectious enteric viral particles. CONCLUSIONS: An ICC-PCR method with a long incubation time using BGMK cells enables the simultaneous detection of enteroviruses and adenoviruses from environmental water samples, including tap water, even with low numbers of viruses. SIGNIFICANCE AND IMPACT OF THE STUDY: A method capable of detecting small numbers of viral particles is necessary.

Seroepidemiology of hepatitis A in patients with chronic liver disease.

Hepatitis A virus (HAV) rarely causes fulminant hepatic failure in the general population. Yet it is a cause of significant morbidity and mortality in patients with chronic liver disease (CLD), in whom routine HAV vaccination is recommended. However, studies of HAV seroprevalence and exposure predictors in populations with CLD are scarce. We have studied a cohort of 473 patients with various causes of CLD between July 2000 and June 2002. Patients were stratified on the basis of age, gender, ethnicity and aetiology of liver disease. The HAV seroprevalence in patients with CLD was compared with that in the general population. We used a logistic regression analysis to identify independent predictors of HAV exposure. Of the 473 patients studied, HAV seroprevalence was available for 454 individuals. HCV, HBV, alcohol, and HCV and alcohol were the causes of CLD in 337, 72, 37 and eight patients, respectively. The overall HAV seroprevalence was 55% in the studied cohort. The age-stratified HAV prevalence for ages 21-30, 31-40, 41-50, 51-60, 61-70 and greater than 70 years was 44, 51, 44, 63, 65 and 64%, respectively. Hispanic ethnicity, Asian ethnicity, alcohol use and ages of 51-70 years were found to be independent predictive variables of prior exposure to HAV. HAV infection in patients with CLD causes considerable morbidity and mortality. We demonstrated that age-stratified seroprevalence of HAV in patients with CLD of various aetiologies is significantly higher than that of the general population, and identified several independent predictors of HAV prior exposure.

Allelic and haplotypic diversity of HLA-A, -B, -C, -DRB1, and -DQB1 genes in the Korean population.

High-resolution human leukocyte antigen (HLA) typing exposes the unique patterns of HLA allele and haplotype frequencies in each population. In this study, HLA-A, -B, -C, -DRB1, and -DQB1 genotypes were analyzed in 485 apparently unrelated healthy Korean individuals. A total of 20 HLA-A, 43 HLA-B, 21 HLA-C, 31 HLA-DRB1, and 14 HLA-DQB1 alleles were identified. Eleven alleles (A*0201, A*1101, A*2402, A*3303, B*1501, Cw*0102, Cw*0302, Cw*0303, DQB1*0301, DQB1*0302, and DQB1*0303) were found in more than 10% of the population. In each serologic group, a maximum of three alleles were found with several exceptions (A2, B62, DR4, DR14, and DQ6). In each serologic group exhibiting multiple alleles, two major alleles were present at 62-96% (i.e. A*0201 and A*0206 comprise 85% of A2-positive alleles). Multiple-locus haplotypes estimated by the maximum likelihood method revealed 51 A-C, 43 C-B, 52 B-DRB1, 34 DRB1-DQB1, 48 A-C-B, 42 C-B-DRB1, 46 B-DRB1-DQB1, and 30 A-C-B-DRB1-DQB1 haplotypes with frequencies of more than 0.5%. In spite of their high polymorphism in B and DRB1, identification of relatively small numbers of two-locus (B-C and DRB1-DQB1) haplotypes suggested strong associations of those two loci, respectively. Five-locus haplotypes defined by high-resolution DNA typing correlated well with previously identified serology-based haplotypes in the population. The five most frequent haplotypes were: A*3303-Cw*1403-B*4403-DRB1*1302-DQB1*0604 (4.2%), A*3303-Cw*0701/6-B*4403-DRB1*0701-DQB1*0201/2 (3.0%), A*3303-Cw*0302-B*5801-DRB1*1302-DQB1*0609 (3.0%), A*2402-Cw*0702-B*0702-DRB1*0101-DQB1*0501 (2.9%), and A*3001-Cw*0602-B*1302-DRB1*0701-DQB1*0201/2 (2.7%). Several sets of allele level haplotypes that could not be discriminated by routine HLA-A, -B, and -DRB1 low-resolution typing originated from allelic diversity of A2, B61, DR4, and DR8 serologic groups. Information obtained in this study will be useful for medical and forensic applications as well as in anthropology.
