Children with deficits in attention,motor control and perception (DAMP) almost grown up: The contribution of various background factors to outcome at age 16 years

Fifty-six children with and forty-five children without deficits in attention, motor control and perception (DAMP) had been recruited from the general population at age 7 years. They were followed up neuropsychiatrically at age 16 years after intermediate term follow up at age 10 and 13 years. Cases were subdivided into those with good and not good outcome on the basis of absence or presence of psychiatric and personality disorders, multiple traumatic accidents and speech and language problems at age 16 years. The presence of DAMP in itself was the strongest predictor of poor outcome. High scores for minor neurological dysfunction, low performance IQ, autistic features at age 7 years and poor reading skills at age 10 and/or 13 years were important background factors in cases with poor outcome. In the small subgroup with poor outcome among those without DAMP at age 7 years, major life events was the most important background factor.

Zusammenfassung 56 Kinder mit und 45 Kinder ohne Störungen der Aufmerksamkeit, der motorischen Kontrolle und der Wahrnehmung (DAMP) waren aus einer Gesamtpopulation 7jÄhriger rekrutiert worden. Sie wurden neuropsychiatrisch im Alter von 16 jahren nachuntersucht, nachdem zwischenzeitliche Untersuchungen im Alter von 10 und 13 Jahren erfolgt waren. Die Probanden wurden in solche mit gutem und nicht gutem Ausgang unterteilt, in AbhÄngigkeit vom Vorliegen psychiatrischer AuffÄlligkeiten, Persönlichkeitsstörungen, multiplen Traumata und Sprech- und Sprachproblemen im Alter von 16 Jahren. Das Vorhandensein von DAMP war der stÄrkste PrÄdiktor für einen schlechten Ausgang. Hohe Werte für leichte neurologische AuffÄlligkeiten, ein niedriger Handlungs-IQ, autistische Züge im Alter von 7 Jahren und schlechte LesefÄhigkeiten im Alter von 10 und/oder 13 Jahren waren wichtige Hintergrundfaktoren bei den Probanden mit einem schlechten Ausgang. In der kleinen Untergruppe mit einem schlechten Ausgang bei den Kindern, die im Alter von 7 Jahren kein DAMP ausgewiesen hatten, bildeten schwerwiegende Lebensereignisse den wichtigsten Hintergrundfaktor.

Résumé Cinquante-six enfants atteints et quarante-cinq enfants non atteints de déficits de l'attention, du contrÔle moteur et de la perception (DAMP), ont été recrutés en population générale à l'âge de 7 ans. Ils ont été évalués sur la plan neuropsychiatrique à l'âge de 16 ans, après des évaluations intermédiaires à l'âge de 10 et 13 ans. Les cas ont été subdivisés entre bons et mauvais devenir sur la base de la présence ou de l'absence de troubles de la personnalité, l'importance du nombre d'accidents traumatiques, les difficultés d'élocution et de langage à 16 ans. La présence de DAMP était en soi, le facteur prédictif le plus important de mauvais devenir. Des scores élevés à des dysfonctionnements neurologiques mineurs, un QI bas, des traits autistiques à l'âge de 7 ans, et de mauvaises capacités en lecture à l'âge de 10 ou 13 ans ont été des facteurs importants dans les cas de mauvais devenir. Dans le petit sous-groupe à mauvais devenir caractérisé par une absence de DAMP à l'âge de 7 ans, des événements de vie marquants ont semblé Être des antécédents importants.

     

Antibody Response Against the Glomerular Basement Membrane Protein Agrin in Patients with Transplant Glomerulopathy

Chronic allograft nephropathy (CAN) of renal allografts is still the most important cause of graft loss. A subset of these patients have transplant glomerulopathy (TGP), characterized by glomerular basement membrane (GBM) duplications, but of unknown etiology. Recently, a role for the immune system in the pathogenesis of TGP has been suggested. In 11 of 16 patients with TGP and in 3 of 16 controls with CAN in the absence of TGP we demonstrate circulating antibodies reactive with GBM isolates. The presence of anti-GBM antibodies was associated with the number of rejection episodes prior to diagnosis of TGP. Sera from the TGP patients also reacted with highly purified GBM heparan sulphate proteoglycans (HSPG). Indirect immunofluorescence with patient IgG showed a GBM-like staining pattern and colocalization with the HSPGs perlecan and especially agrin. Using patient IgG, we affinity purified the antigen and identified it as agrin. Reactivity with agrin was found in 7 of 16 (44%) of patients with TGP and in 7 of 11 (64%) patients with anti-GBM reactivity. In conclusion, we have identified a humoral response against the GBM-HSPG agrin in patients with TGP, which may play a role in the pathogenesis of TGP.

Herpes zoster infection as an immune reconstitution inflammatory syndrome in HIV-seropositive subjects: a review.

The use of highly active antiretroviral therapy (HAART) in the management of human immunodeficiency virus (HIV) infection has resulted paradoxically in the worsening of clinical symptoms of previously subclinical infections, such as herpes zoster (HZ), herpes simplex, angular cheilitis, warts, tuberculosis, hepatitis B and C, cytomegalovirus retinitis, and others, as a result of substantial reconstitution of the host's immune responses. This phenomenon is referred to as immune reconstitution inflammatory syndrome (IRIS). It may affect up to 32% of HIV-seropositive subjects within a wide range of time after the initiation of HAART, but mainly after 8-12 weeks. Mucocutaneous HZ accounts for 7%-12% of the diseases associated with HIV infection that become worse again when the subject's immunity improves from the administration of HAART. It usually occurs after 4 weeks from the initiation of HAART, and under these circumstances the clinical symptoms and natural course of mucocutaneous HZ are similar to those in HIV-seropositive subjects who do not manifest IRIS.     

Migration and wear of hydroxyapatite-coated press-fit cups in revision hip arthroplasty: A radiostereometric study

Screw-fixated and hydroxyapatite-coated press-fit cups were studied using radiostereometry in 29 revision and 14 primary arthroplasties. The acetabular defects in the revision cases varied from none to type 3 (wall defects) according to Gustilo—Pasternak. Morsellized allograft was used in 25 revisions. Nine of these cups rested on less than 50% living bone. After 2 years, the mean migration in the revised group reached 0.36, 0.21, and 0.49 mm in the horizontal, longitudinal, and anteroposterior (AP) directions. The mean rotations varied between 0.5° and 0.7° depending on direction. The primary implants displayed smaller mediolateral migration and AP tilt. The mean proximal wear rate for the whole group was 0.11 mm/y. A central gap on the postoperative AP view implied less migration. The size of the preoperative bone defects or amount of bone—graft used had no influence on the migration. Despite extensive use of morsellized allograft, this implant displayed the smallest migration so far reported in revision hip arthroplasty.     

A comparison of preoperative and intraoperative evaluation of patients undergoing pelvic reconstructive surgery for pelvic organ prolapse using the pelvic organ prolapse quantification system

OBJECTIVE: To compare the pre- and intraoperative situation using the POP-Q system during optimally standardized conditions of both examinations. STUDY DESIGN: In a prospective observational study, 108 women were compared. The POP-Q in the outpatient department (preoperative) was compared with the situation just prior to surgery after full anesthesia was reached (intraoperative). During the intraoperative measurement, traction with 0.5 kg force was applied on all relevant places. RESULTS: The pre- and intraoperative measurements were all significant correlated with the R-values between 0.43 and 0.85. All six points, which are measured during the POP-Q, were more prolapsed in the intra- as compared with the preoperative situation. The points Bp, C, and D were significantly more prolapsed, but for the points Aa, Ba, and Ap this was not significant. Fifteen patients were upstaged by the intraoperative measurements and five patients were downstaged in the overall POP-Q grading system. CONCLUSIONS: Intraoperative evaluation of the prolapse can reveal significant changes as compared with the preoperative situation. In general, the prolapse is more pronounced especially in the middle and posterior compartment.     

Static footprint analysis: a time-saving functional evaluation of nerve repair in rats.

Walking track analysis is a widely accepted technique for functional evaluation after sciatic nerve repair in rats, but it is labour-intensive. In 2000, Bervar described a time-saving digitised static footprint analysis. In that study there were good correlations between the traditional sciatic function index (SFI) and the newly-developed static sciatic index (SSI) and static toe spread factor (TSF), respectively. Despite promising results, static footprint analysis is still not widely used. The present study was designed to validate it. After transection of the sciatic nerve, end-to-end repair was assessed using video recorded dynamic and static footprints in 45 Wistar rats. We found an even better correlation between the SFI and both the SSI and the static TSF. In conclusion, static footprint analysis is a time-saving and easy technique for accurate functional assessment of peripheral nerve regeneration in rats.     

Assessment of nutritional status in children with cystic fibrosis: conventional anthropometry and bioelectrical impedance analysis. A cross-sectional study in Dutch patients

BACKGROUND: Assessment of nutritional status in children with cystic fibrosis (CF) is clinically relevant. Methods to measure nutritional status should be reliable and non-invasive, and reference values should be available. AIM: To compare weight and height measurements and measurements of specific body compartments in children with CF. METHODS: In a cross-sectional survey of 58 children with CF (28 females), we compared height and weight (expressed as: weight-for-height, body mass index (BMI), height-for-age and weight-for-age) with fat mass (skinfold sum (SFS)), muscle mass (upper arm circumference (UAC)) and bioelectrical impedance analysis (BIA). Results were expressed as Z-scores, using Dutch reference values. RESULTS: BMI and weight-for-height were within the normal range (mean Z-score (range): -0.13 (-1.5, 2.7) and -0.02 (-1.7, 2.8)). Weight and height corrected for age were below normal (mean Z-score (range): -0.79 (-2.4, -0.05) and -1.2 (-2.8, 1.4) (P<0.01)). Lean body mass by skinfold sum (LBM(sfs)), UAC and BIA were also significantly below reference values (mean Z-score (range): -0.9 (-2.2, 1.8), -0.95 (-2.4, 1.8) and -1.1 (-3.6, 1.0) (P<0.01)). Lean body mass (LBM) by BIA correlated with LBM(sfs). BIA systematically underestimated LBM in both CF patients and in control subjects. CONCLUSION: Nutritional status of children with CF must be evaluated, using age-corrected weight and height expressed in Z-score. LBM estimated by SFS, UAC and by BIA appear to be useful, although longitudinal studies in CF children should be performed to evaluate their clinical significance in detecting changes in nutritional status.     

Are cytokines possible mediators of cancer cachexia?

The possible role of cytokines in the development of cancer cachexia was reviewed from the literature. Tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, IL-6, interferon (IFN)-gamma and leukemia inhibitory factor (LIF) can elicit many but not all host changes seen in cancer cachexia, including loss of appetite, loss of body weight, and the induction of acute-phase protein synthesis. However, these cytokines are not always demonstrated in the circulation of the cancer patients. The inability to detect circulating cytokines may be due to their low rate of production, their short half-life and rapid clearance from plasma, or their mode of action (autocrine or paracrine). Different cytokines are induced to stimulate the same response. This is very different from hormonal regulation, where a hormone acts on a cell directly through a specific receptor without depending on other mediators. Specific antibodies including anti-IFN-gamma, anti-TNF and anti-IL-6 antibodies, as well as the cyclooxygenase inhibitor indomethacin, have been used to reverse cancer cachexia. Overlapping physiologic activities make it unlikely that a single substance is the sole cause of cancer cachexia. It is hoped that further investigation on other cytokines and their possible relationships with hormones will help to clarify the mechanisms of cancer cachexia in the near future.This work was supported by a grant from the Japan-Sweden Foundation in 1991.
