- To assess B12 and folate deficiency after continent urinary diversion via a Kock continent urinary reservoir in children and adolescents.Ten boys and 10 girls (10.8-18 years old at surgery) were operated with a Kock reservoir and followed for 5-12 years (mean 8.5). The follow-up period was divided into early (3 months-5 years, EFU) and late (5-12 years, LFU) follow-up. Patients were investigated for haemoglobin, serum iron, total iron binding capacity (TIBC), serum Vitamin B12, serum and blood folate, methylmalonic acid (MMA), homocystine and glomerular filtration rate.Two patients developed subnormal B12 values (median 107.5 pmol/l), one at the EFU, and the other at LFW. The B12 value decreased during the LFU compared to the EFU in nine patients, but it was still within the normal range. Two patients with renal impairment had elevated MMA with normal B12 values. Five patients had high values of homocystine with folate deficiency and/or B12 deficiency and renal impairment. Plasma folate mean value was normal during the whole follow-up. Blood folate was below normal in five patients at the EFU. Two of these five patients, in addition to three patients, had low values at the LFU. Three of four patients with remaining short terminal ileum (20-45 cm) had normal B12 values at both the EFU & LFU and one had low values at the LFU. Six patients had subnormal GFR at the LFU.To a similar degree as in adults, Vitamin B12, folate and iron deficiency can occur in children and adolescents after continent urinary diversion using an ileal segment. Therefore, Vitamin B12 and folate should be monitored regularly in these patients. Serum MMA and homocystine may offer increased detection of Vitamin B12 deficiency, especially in the patients with normal renal function. Vitamin B12 deficiency is neither correlated with the time elapsed since surgery, nor with the ileum length. Patients are usually asymptomatic, so patients with true B12 deficiency should be identified and placed on life-long Vitamin B12 therapy. An adequate synthetic folic acid as supplements or fortified food is recommended for patients with folate deficiency.

- OBJECTIVE: To assess quality of life after continent ileal reservoir diversion in children and adolescents. MATERIAL AND METHODS: Nine boys and 9 girls (10.8-18 years old at surgery) were operated with a Kock reservoir and followed for 5-12 years. They participated in an interview using a questionnaire based on the Swedish self-esteem inventory, "I think I am". The questionnaire consisted of 76 questions that covered medical, physical, psychological, social, body image and sexual aspects. RESULTS: Six of 18 patients had some difficulties on catheterization. Five complained of pain or bleeding during evacuation. Two patients had slight urinary leakage between evacuations and 6 had mucus secretion. Ten patients had diarrhea with different frequencies. Physical activities were not hampered by the operation in any patient. Instead, activities such as full day outside home, friend at home overnight, using all types of clothes, and participation in camps were increased in 8, 6, 5 and 5 patients, respectively. All patients but 2 had an excellent relation with friends and family members. More than half of patients had excellent positive self-esteem and body image and the rest had very good self-esteem. However, some patients were concerned about how they looked and felt that life was unfair to them. CONCLUSIONS: The patients were satisfied with their operation. They were physically active and declared a positive perspective regarding self-esteem and body image. The medical problems related to the operation did not have any negative influence on the self-esteem or body image. The choice of the operation can only be determined on the basis of an attentive dialogue between surgeon, child and parents.

-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To study the effect of antiretroviral combination treatment on intrathecal immunoactivation in HIV-1 infection. METHOD: Lumbar punctures were performed at baseline, and after 4 months, 1 and 2 years on 30 neurologically asymptomatic, treatment-naive HIV-1-infected patients started on antiretroviral treatment with three or more drugs. Levels of neopterin, beta2-microglobulin and HIV-1 RNA were measured in cerebrospinal fluid (CSF) and blood. RESULTS: All patients continued the study until the 4-month follow-up, although seven discontinued before the 1-year control, and an additional five discontinued before the control after 2 years. Neopterin, beta2-microglobulin and HIV-1 RNA decreased significantly both in CSF and blood, but although 100% of the patients decreased their CSF concentrations of beta2-microglobulin and HIV-1 RNA to normal levels, only 55% had normal CSF neopterin concentrations after 2 years treatment. CONCLUSIONS: In addition to CSF viral load, antiretroviral combination therapy substantially decreases the intrathecal immunoactivation as reflected by CSF neopterin and beta2-microglobulin in neuroasymptomatic HIV-1-infected patients. However, almost half of the patients still have slightly increased CSF neopterin concentrations after 2 years of effective treatment, which might reflect an ongoing low-grade viral replication in brain tissue.

- The genes encoding Caspase-9 and DFF45 have both recently been mapped to chromosome region 1p36.2, that is a region alleged to involve one or several tumour suppressor genes in neuroblastoma tumours. This study presents an update contig of the 'Smallest Region of Overlap of deletions' in Scandinavian neuroblastoma tumours and suggests that DFF45 is localized in the region. The genomic organization of the human DFF45 gene, deduced by in-silico comparisons of DNA sequences, is described for the first time in this paper. In the present study 44 primary tumours were screened for mutation by analysis of the genomic sequences of the genes. In two out of the 44 tumours this detected in the DFFA gene one rare allele variant that caused a non-polar to a polar amino acid exchange in a preserved hydrophobic patch of DFF45. One case was hemizygous due to deletion of the more common allele of this polymorphism. Out of 194 normal control alleles only one was found to carry this variant allele, so in respect of it, no healthy control individual out of 97 was homozygous. Moreover, our RT-PCR expression studies showed that DFF45 is preferably expressed in low-stage neuroblastoma tumours and to a lesser degree in high-stage neuroblastomas. We conclude that although coding mutations of Caspase-9 and DFF45 are infrequent in neuroblastoma tumours, our discovery of a rare allele in two neuroblastoma cases should be taken to warrant further studies of the role of DFF45 in neuroblastoma genetics.

- Dental phobia is a widespread problem, which can have significant impact on the individual's health and daily life. This grounded theory study aims to explore the situation of dental phobic patients: how dental phobia interferes with their normal routines and functioning, social activities and relationships, what factors contribute to the maintenance of dental fear and how they cope with their fear. In the qualitative analysis of thematized in-depth interviews four main categories were developed: threat to self-respect and well-being, avoidance, readiness to act and ambivalence in coping. The results show that several psychological and social factors interact in determining how dental phobic individuals cope with their fear, and demonstrate in what way dental fear affects their daily lives.

- Dental phobic patients' view of dental anxiety and experiences in dental care: a qualitative study The aim of this study was to explore and describe dental phobic patients' perceptions of their dental fear and experiences in dental care. The study sample consisted of 18 participants (12 women), with a mean age of 39.4 years, selected consecutively from patients applying for treatment at a specialized dental fear clinic in G?teborg, Sweden. Dental fear, assessed by the Dental Anxiety Scale, showed score levels well over established levels for severe dental fear. The method for sampling and analysis was inspired by the constant comparative method for Grounded Theory (GT). The thematized in-depth interviews took place outside the clinic and lasted for 1-1.5 h. All the interviews were conducted by the first author (KHA), audiotaped and transcribed verbatim. Three higher-order categories were developed and labelled existential threat, vulnerability and unsupportive dentist. Existential threat was identified as the core category, describing the central meaning of the subjects' experiences in dental care. The core category included two dimensions, labelled threat of violation and threat of loss of autonomy and independence. The core category and the descriptive categories are integrated in a model framing the process of dental fear, as described by the informants. In conclusion, the onset of dental fear was commonly related to individual vulnerability and to traumatic dental care experiences, where perceived negative dentist behaviour played a significant role. The patient was caught in a 'vicious circle' that was difficult to break, and where fear and anxiety were maintained by negative expectations about treatment and about patient's own ability to cope in dental care situations.

Protection against Helicobacter pylori infection following immunization is IL-12-dependent and mediated by Th1 cells
- 2002
-
Ingår i: J Immunol. ; 169:12, s. 6977-84
-
Tidskriftsartikel (refereegranskat)abstract
- The regulatory roles of Th1 and Th2 cells in immune protection against Helicobacter infection are not clearly understood. In this study, we report that a primary H. pylori infection can be established in the absence of IL-12 or IFN-gamma. However, IFN-gamma, but not IL-12, was involved in the development of gastritis because IFN-gamma(-/-) (GKO) mice exhibited significantly less inflammation as compared with IL-12(-/-) or wild-type (WT) mice. Both IL-12(-/-) and GKO mice failed to develop protection following oral immunization with H. pylori lysate and cholera toxin adjuvant. By contrast, Th2-deficient, IL-4(-/-), and WT mice were equally well protected. Mucosal immunization in the presence of coadministered rIL-12 in WT mice increased Ag-specific IFN-gamma-producing T cells by 5-fold and gave an additional 4-fold reduction in colonizing bacteria, confirming a key role of Th1 cells in protection. Importantly, only protected IL-4(-/-) and WT mice demonstrated substantial influx of CD4(+) T cells in the gastric mucosa. The extent of inflammation in challenged IL-12(-/-) and GKO mice was much reduced compared with that in WT mice, indicating that IFN-gamma/Th1 cells also play a major role in postimmunization gastritis. Of note, postimmunization gastritis in IL-4(-/-) mice was significantly milder than WT mice, despite a similar level of protection, indicating that immune protection is not directly linked to the degree of gastric inflammation. Only protected mice had T cells that produced high levels of IFN-gamma to recall Ag, whereas both protected and unprotected mice produced high levels of IL-13. We conclude that IL-12 and Th1 responses are crucial for H. pylori-specific protective immunity.

- OBJECTIVE: To investigate the risk of asthma in hairdressers. METHODS: The incidence of asthma was retrospectively estimated in a Swedish nationwide study including all female hairdressers certified from vocational schools from 1970 to 1995, and a stratified sample of women from the general population were referents. A postal questionnaire included questions on respiratory tract symptoms, atopy, smoking, working periods as a hairdresser, and number of specific hair treatments performed/week. Reported exposures were validated by occupational hygienists. Rate ratios of incidence (IRRs) of asthma were estimated by Poisson regression, adjusted for calendar year of observation, hay fever, smoking, and region of domicile. RESULTS: The crude incidences of asthma/1000 person-years were: 3.9 during active years as a hairdresser, 2.8 among the hairdressers when not working in the profession, and 3.1 among the referents. The corresponding IRR for being an active hairdresser compared with the referents was 1.3 (95% confidence interval (95% CI) 1.0 to 1.6). Moderate effects on risk of asthma were found both from hairdressing work (IRR=1.6 (1.1 to 2.2) among never-smokers) and from smoking (IRR=1.6 (1.2 to 2.2) among referents). However, the combined effect from hairdressing work and smoking (IRR=1.5 (1.0 to 2.1)) was less than expected (p=0.02). No effect modification by respiratory atopy was found. The hairdressers most often performing hair bleaching treatments (IRR=1.5 (0.7 to 3.0)) or using hair spray (IRR=1.4 (0.8 to 2.4)) had, compared with the most infrequent users, a slightly, but not significantly higher incidence of asthma. Exposure to persulphates in hair bleach was estimated to be 0.04-0.15 mg/m(3) during mixing of the powder. Reported average number of bleaching treatments agreed well with those performed according to a diary. CONCLUSIONS: Active hairdressing work was associated with a moderately increased incidence of asthma among lifelong non-smokers. The results are moderately supportive, but not conclusive, of associations between asthma and exposure to hair bleach or hair spray.

- To assess the effects of breast feeding habits on sudden infant death syndrome (SIDS).The analyses are based on data from the Nordic Epidemiological SIDS Study, a case-control study in which parents of SIDS victims in the Scandinavian countries between 1 September 1992 and 31 August 1995 were invited to participate, each with parents of four matched controls. The odds ratios presented were computed by conditional logistic regression analysis.After adjustment for smoking during pregnancy, paternal employment, sleeping position, and age of the infant, the adjusted odds ratio (95% CI) was 5.1 (2.3 to 11.2) if the infant was exclusively breast fed for less than four weeks, 3.7 (1.6 to 8.4) for 4-7 weeks, 1.6 (0.7 to 3.6) for 8-11 weeks, and 2.8 (1.2 to 6.8) for 12-15 weeks, with exclusive breast feeding over 16 weeks as the reference. Mixed feeding in the first week post partum did not increase the risk.The study is supportive of a weak relation between breast feeding and SIDS reduction.

- Galectins are a group of lactose-binding proteins widely distributed in nature. Twelve mammalian galectins have so far been identified, but their functions are to a large extent unknown. In this work we study galectin-1 in its interaction with human neutrophils, with regard to both cell surface binding and activation of the superoxide-producing NADPH-oxidase. We show that galectin-1 is able to activate the neutrophil NADPH-oxidase, provided that the cells have been primed by extravasation from the blood into the tissue, an activation pattern that is similar to that of galectin-3. Using in vitro priming protocols, the galectin-1 responsiveness was found to correlate to granule mobilization and galectin-1 binding to the cells, suggesting the presence of granule-localized receptors that are up-regulated to the cell surface upon priming. By galectin-1 overlay of fractionated neutrophils we identified potential galectin-1 receptor candidates localized in the membranes of the secretory vesicle and gelatinase granules. The binding of galectin-1 and galectin-3 to neutrophil proteins was compared, as were the dose dependencies for activation by the two lectins. The results suggest that, although similarities are found between the two galectins, they appear to activate the NADPH-oxidase using different receptors. In conclusion, galectin-1 appears to have proinflammatory functions, mediated through activation of the neutrophil respiratory burst.
