Shortened hospital stay for childhood bone and joint infections: Analysis of 265 prospectively collected culture-positive cases in 1983-2005

Abstract Background: In recent decades the treatment of childhood acute bone and joint infections has shifted towards shorter antibiotic courses and rapid transition to oral therapy. Methods: We prospectively collected 265 culture-positive cases of non-neonatal bone and joint infections in Finnish children during 1983-2005. The duration of antimicrobial treatment and the extent of surgery were defined in the study protocol, but for ethical reasons, the liaison clinician determined the time of discharge using normalization of the serum C-reactive protein (CRP) level as a yardstick. We examined changes during the study in the distribution of causative organisms, severity of disease, and length of hospital stay. Results: Staphylococcus aureus was overwhelmingly the most common causative agent throughout the study, whereas Haemophilus influenzae type b was eliminated soon after the introduction of vaccination. The mean time from initial symptoms to presentation remained the same at 4 days, and no significant change was observed in the severity of disease, CRP, or the rate of sequelae. The mean duration of intravenous antibiotic administration was only 4 days. The average hospital stay shortened significantly from 13 days to 9 days (p =?0.0001). Conclusions: The shortened hospital stay was not due to a change in the anatomical site of these infections, but to simplified treatment. Considerable savings in hospital stay, and thus costs, are feasible in osteoarticular infections of childhood by using CRP in monitoring the disease and shortening intravenous treatment by a swift move to per oral administration.     

Visual rightward spatial bias varies as a function of age

Age-related changes in visual spatial biases in children, young adults, and older adults were studied with unilateral and bilateral stimulus conditions in fast-paced linguistic and non-linguistic attention tasks. Only rightward spatial biases were observed. The incidence of the biases changed as a function of age: in childhood and in old age the rightward spatial biases were more common than in young adulthood. The present rightward spatial biases were similar to those observed in the corresponding auditory spatial linguistic and non-linguistic attention tests (Takio, Koivisto, Laukka, & Hämäläinen, 2011) and in the dichotic listening forced-attention task (Takio et al., 2009). We suggest that the multimodal rightward spatial bias observed under intensive attentional load is related to a right hemispace preference and modulated by age-dependent changes in executive functions.     

Physiological responses to emotional excitement in healthy subjects and patients with coronary artery disease

Emotional excitement may trigger cardiovascular (CV) events, particularly in patients with coronary artery disease (CAD). Our aim was to compare changes in various biomarkers in CAD patients and age-matched healthy male subjects during “real-life” emotional excitement. Enthusiastic male ice hockey spectators (CAD n = 18, healthy subjects n = 16) attended Finnish national ice hockey play-off matches. Heart rate variability, plasma catecholamines, endothelin-1 (ET-1) and interleukin-6 (IL-6) were determined at the baseline and during the match. A significantly more marked increase in both ET-1 and IL-6 was observed in CAD patients compared with healthy subjects during the match (time × group interaction p = 0.009 and p = 0.018 for ET-1 and IL-6, respectively). The high-frequency power of R–R intervals decreased in CAD patients (p < 0.001) but did not change in healthy subjects (p = ns, time × group interaction p < 0.001). Changes in adrenaline and noradrenaline did not differ between the groups. Emotional excitement causes more marked increases of markers of vasoconstriction and acute inflammation and withdrawal of cardiac vagal regulation in patients with CAD.     

Quality evaluation of oral health record-keeping for Finnish young adults

The objective of this study was to assess the quality of oral health record-keeping in public oral health care in relation to dentists' characteristics. A random computerized selection of 239 subjects, born in 1966-71 and clinically examined during 1994 in an administrative unit of the public oral health service in southern Finland, included 4-5 cases per dentist, the number of dentists being 50. Data concerning actual clinical examinations and treatment courses carried out in public dental clinics came from original oral health records. Criteria for assessment of oral health record entries were based on Finnish health legislation and detailed instructions of health authorities. The results showed that each patient's identity was available in 90% of documents. Recordings concerning continuity of comprehensive care were infrequent; a questionnaire concerning each patient's up-to-date health history was in only 26% of the oral health records. Notes concerning each patient's bite and function of the temporomandibular joint were in 37% of the records, notes about oral soft tissues were in 11%, and the check-up interval was recorded in 21%. Recording of indices on periodontal and dental status varied greatly; the community periodontal index of treatment need was found in 93% and the index of incipient lesions in 16% of the records. Female dentists and dentists younger than 37 years tended to record more information. Dentists should be encouraged to better utilize the options offered by oral health records for individual treatment schemes.     

Multiple co-infections of rodents with hantaviruses, Leptospira, and Babesia in Croatia

Hantaviruses, Leptospira spp., and Babesia spp. are rodent-borne pathogens present worldwide. We studied multiple co-infections of small rodents in Croatia with all three pathogens. Twenty-eight Apodemus flavicollis and 16 Myodes glareolus were tested for the presence of hantavirus RNA by real-time RT-PCR, Leptospira strains by renoculture method and Babesia DNA by PCR. Anti-hantavirus antibodies and anti-Leptospira antibodies were detected by serological methods. Very high infection rates with each pathogen were found in A. flavicollis: 20 of 28 rodents (71%) were infected with Dobrava virus, 13 rodents (46%) were infected with Leptospira, and 5 rodents (18%) were infected with Babesia. Multiple co-infections with all three pathogens were found in 3 of 28 (11%) A. flavicollis animals, suggesting that the same rodent host can be infected with several pathogens at the same time. Dual infections with both hantaviruses and Leptospira were found in 7 of 44 rodents (16%), with hantaviruses and Babesia in 2 rodents (5%), and double infection with both Leptospira and Babesia were found in 1 rodent (2%). Since hantaviruses, Leptospira, and Babesia have similar geographical distributions, it is to be expected that in other parts of the world multiple co-infections, representing a serious threat to public health, can be found.
