Linguistic and pragmatic aspects of narration in Finnish typically developing children and children with specific language impairment

This study investigates narratives of Finnish children with specific language impairment (SLI) from linguistic and pragmatic perspectives, in order to get a comprehensive overview of these children’s narrative abilities. Nineteen children with SLI (mean age 6;1 years) and 19 typically developing age-matched children participated in the study. Their picture-elicited narrations were analysed for linguistic productivity and complexity, grammatical and referential accuracy, event content, the use of mental state expressions and narrative comprehension. Children with SLI showed difficulties in every aspect of narration in comparison to their peers. Only one measure of productivity, the number of communication units, did not reach statistical significance. Not only was linguistic structure fragile but also pragmatic aspects of storytelling (referencing, event content, mental state expressions and inferencing) were demanding for children with SLI. Results suggest that pragmatic aspects of narration should be taken into account more often when assessing narrative abilities of children with SLI.     

Diagnostic utility of urine cytology in detection of decoy cells in renal transplant patients: Report of five cases and review of literature

BK polyoma virus (PV) is one of the commonest post‐transplant viral infections, affecting approximately 15% of renal transplantation recipients, leading to graft failure in more than half of cases. The epithelial cells with polyoma viral inclusions in urine cytology specimens are termed “decoy cells” to caution pathologists not to misdiagnose these cells as cancer cells. The infected cells in urinary sediments are characterized by enlarged nucleus, basophilic intranuclear homogenous inclusions, and ground glass chromatin, which may cause diagnostic error in urine cytology. We report five cases of renal transplant patients, in which urine sample was positive for decoy cells. Routine urine cytology of post renal transplant patients with worsening renal function is a useful screening procedure to rule out PV reactivation, before ascertaining transplant rejection. Its cost‐effectiveness in addition to the short processing time makes it an invaluable tool in the evaluation of transplant recipients with symptoms suggestive of graft rejection.     

Maternal Genetic Variants of IL4/IL13 Pathway Genes on IgE With "Western or Eastern Environments/Lifestyles"

Purpose

We investigated maternal genetic effects of four IL-4/IL-13 pathway genes as well as their interactions with the "Western or Eastern lifestyles/environments" on IgE in Karelian children.

Methods

This study included 609 children and their mothers. Total IgE levels in children and mothers were measured and 10 single nucleotide polymorphisms (SNPs) in IL-4, IL-4Ra, IL-13, and STAT6 were genotyped in mothers and their children.

Results

The maternal G allele of IL-13 130 (rs20541) was significantly (P=0.001) associated with decreased IgE in children in the Karelian population (Pooling Finnish and Russian children), as well as in Finnish (P=0.030) and Russian children (P=0.018). The IgE levels were significantly (P=0.001) higher in Russian children whose mothers were homozygous for the G allele of the IL-4Ra 50 (rs1805010) SNP than that in Russian children of mothers who were AG heterozygotes or AA homozygotes. After accounting for children''s genotypes, we observed interactive effects on children''s IgE for maternal IL-13 130 genotypes (P=0.014) and maternal IL-4Ra 50 genotypes (P=0.0003) with "Western or Eastern" lifestyles/environments. With the adjustment for multiple comparisons using a false discovery rate (FDR) of 0.05, the interactive effect of the maternal IL-4Ra50 SNP was significant.

Conclusion

Maternal genetic variants in IL-4/IL-13 pathway genes, such as IL-13 130 and IL-4Ra50, influenced IgE levels in school children that were independent of the children''s genetic effects. These effects differ in "Western or Eastern" environments.     

Hormonal control on enzymes of osmoregulation in a teleost, Anabas testudineus (BLOCH): an in vivo and in vitro study

Hormonal control of osmoregulation in teleosts is not well understood. Role of cGH, oGH, PRL, T3 and insulin on gill Na+,K+-ATPase, Mg2+ and Ca2+ ATPases was studied in A. testudineus. Short term administration of cGH, PRL or T3 significantly increased Na+,K+-ATPase, Mg2+ and Ca2+ ATPases, while oGH influenced only Mg2+ ATPase, and insulin stimulated Na+,K+-ATPase. Long-term treatment with cGH and PRL also significantly increased Na+,K+-ATPase activity. GH had an additive with T3 on stimulating Na+,K+-ATPase activity. In vitro addition of cGH and oGH also had definite stimulatory effect on gill Na+,K+-ATPase except for 2ng oGH. Bromocryptine treatment caused a significant reduction on Na+,K+-ATPase activity. Both in vivo and in vitro treatments of cGH and PRL independently reversed the action of bromocryptine on Na+,K+-ATPase. Combined treatment of cGH+PRL was more prominent in stimulating Na+,K+-ATPase in bromocryptine treated fish. Present study reveals that GH, PRL and T3 have definite regulatory role on enzymes of osmoregulation in the teleost Anabas testudineus.     

The radiographic criterion in the 1987 revised criteria for rheumatoid arthritis. Reassessment in a prospective study of early disease

Objective. To assess the radiographic criterion in the 1987 revised criteria for the classification of rheumatoid arthritis (RA), in patients with early RA. Methods. The diagnostic value of radiologic changes in the hands was compared with that of radiologic changes in the feet, in a prospective study of 78 patients with early definite or classic RA (symptoms for ≤12 months) according to the 1958 criteria. Results. At entry, 23% of the patients had erosions only in metatarsophalangeal (MTP) joints, 6% only in hands, and 5% both in hands and in feet. After 2 years of followup, 29% of the patients had only MTP joint erosions and 3% had only hand erosions. At study entry, the level of clinical activity in patients with erosions in the feet only was lower than that in other patients, and 44% of these patients would not have been diagnosed as having RA by the 1987 criteria. Conclusion. In early RA, radiographic changes in the feet seem to be a more sensitive criterion than radiographic changes in the hands. Therefore, addition of radiographic evaluation of the feet to the revised criteria may improve the classification of recent-onset RA.     

Outcome in patients with early rheumatoid arthritis treated according to the “sawtooth” strategy

Objective. To investigate the outcome of early rheumatoid arthritis (RA) when treated according to the “sawtooth” strategy, and to compare the results with the findings of other studies. Methods. In this prospective study, 142 patients with early RA were treated actively with slow-acting antirheumatic drugs (SAARDs) for an average of 6.2 years, and were closely monitored clinically. Several outcome measures were applied, and the results were compared with findings in previously described cohorts. Results. The mean cumulative number of SAARDs used during the study was 3.3. Treatment changes were made because of inefficacy more often than because of adverse events. The percentage of patients whose disease entered remission increased with time to 32% (45 of 142). Only 24% of the patients (34 of 142) had deterioration to Steinbrocker functional class III or IV. The “sawtooth” treatment strategy seemed to improve the outcome of the patients with early RA. Conclusion. In the majority of patients with early RA, “sawtooth” therapy remains beneficial for at least 6 years. However, in one-fourth of the patients, the disease fails to respond to this drug treatment strategy.     

Health and social service use among old people in the last 2 years of life

This study focuses on differences in health and social service use in the last 2 years of life among Finnish people aged 70–79, 80–89, and 90 or older and on the variation in service use in the various municipalities. The data set, derived from multiple national registers, consists of 75,578 people who died in 1998–2001. The services included hospitals and long-term-care facilities, use of regular home care, and prescribed medicines. General hospital and public long-term care were the services most commonly used: general hospitals for younger age groups and public long-term care for older groups. The number of inpatient days in hospital was lower with increasing age, but older age groups used long-term care more frequently. Men had more hospital inpatient days than women, but women used more long-term care. The number of hospital inpatient days increased rapidly in the last months of life, almost doubling in the final month. Days in public long-term care increased regularly in the last 2 years of life. Variation in both hospital and long-term care by municipality was remarkable. The results indicate that, among people aged 70 years and older, age is a major determinant of care in the last 2 years of life. The variation in the use of care by municipality and the differences between men and women deserve more detailed analysis in future.     

The effect of a taste-enhancement process for cold-stored raw shell-stock oysters (<Emphasis Type="Italic">Crassostrea virginica</Emphasis>) on the spillage of human enteropathogens

A taste-enhancement process for cold-stored, raw shell-stock Crassostrea virginica oysters (i.e., application of table salt to shells) when externally contaminated with human enteropathogens intensified spillage of these enteropathogens to oyster’ storage containers (77% compared to 27% for controls) but did not, however, cause contamination of edible oyster tissue.     

Mucociliary function of the eustachian tube in the eustachian tube dysfunction

Background: Most of the tests to evaluate the eustachian tube (ET) function are focused on the ventilation function of the ET.

Aim: Here we evaluate mucociliary function of the ET in patients with ET dysfunction.

Materials and methods: Ten patients with ET dysfunction were enrolled into the study. Six patients had chronic tympanic membrane retraction and four patients had chronic middle ear effusion (MEE). All patients had intact tympanic membranes. Tympanometry and clinical examinations were done to all patients. Mucociliary function was evaluated with technetium labeled albumin and blue dye. Tympanometry and clinical examinations were done to six patients with chronic tympanic membrane retraction and four patients with chronic middle ear effusion (MEE). Mucociliary function of the ET was evaluated with technetium labeled albumin and blue dye placed into middle ear through an intact tympanic membrane and followed from nasopharynx ET orifice (blue dye) and with gamma camera (technetium).

Results: Blue dye was observed in tubal orifice in six (6 of 10) patients during 30?min observation. Five of those patients (5 of 6) had tympanic membrane retraction and one patient (1 of 6) had MEE. Tracer activity decreased from middle ear in six (6 of 10) patients. Four of those patients had tympanic membrane retraction and two had MEE.

Conclusion: Mucociliary function of the ET seems to be better in patients with tympanic membrane retraction than patients with middle ear effusion.

Significance: Mucociliary function of the ET is an important function for middle ear aeration, blue dye test is easily available to be used also in clinical practice.
