Adiponectin in relation to childhood myeloblastic leukaemia
Adiponectin, an adipocyte-specific secretory protein known to induce apoptosis, has been reported to be inversely related to breast and endometrial cancers and recently found to inhibit proliferation of myeloid but not lymphoid cell lines. We hypothesised that adiponectin may be inversely associated with acute myeloblastic leukaemia (AML), but not with acute lymphoblastic leukaemia of B (ALL-B) or T (ALL-T) cell origin in children. Blood samples and clinical information were collected over the period 1996–2000 from 201 children (0–14 years old) with leukaemia (22 AML, 161 ALL-B and 18 ALL-T cases) through a national network of childhood Hematology-Oncology units in Greece and from 201 controls hospitalised for minor pediatric ailments. Serum adiponectin levels were measured under code, at the Beth Israel Deaconess Medical Center, Boston, MA, USA using a radioimmunoassay procedure. Each of the three leukaemia groups was compared with the control group through multiple logistic regression. Odds ratios (OR) and 95% confidence intervals (95% CI) for an increase of adiponectin equal to 1 s.d. among controls were estimated controlling for gender, age, as well as for height and weight, expressed in age–gender-specific centiles of Greek growth curves. Adiponectin was inversely associated with AML (OR=0.56; 95% CI, 0.34–0.94), whereas it was not significantly associated with either ALL-B (OR=0.88; 95% CI, 0.71–1.10) or ALL-T (OR=1.08; 95% CI, 0.67–1.72). Biological plausibility and empirical evidence point to the importance of this hormone in the pathogenesis of childhood AML
Isoniazid-triggered pure red cell aplasia in systemic lupus erythematosus complicated with myasthenia gravis.
A 47-year-old woman who had been treated for systemic lupus erythematosus (SLE) with myasthenia gravis (MG) was admitted to our hospital with acute onset of severe anemia after administration of isoniazid. Pure red cell aplasia (PRCA) was confirmed by elevated serum iron levels, reticulocytopenia and bone marrow aspiration showing a remarkable reduction of erythroblasts. Finally, cyclosporine A successfully improved PRCA. Although both SLE and MG have the potential complication of PRCA, we report here a case of isoniazid-triggered PRCA
Disparities of infant and neonatal mortality trends in Greece during the years of economic crisis by ethnicity, place of residence and human development index: a nationwide population study
OBJECTIVE: To study trends of infant mortality rate (IMR) and neonatal mortality rate in Greece during the period 2004-2016 and explore the role of sociodemographic factors in the years of crisis. DESIGN: Nationwide individual data for live births and infant (0-11 months) deaths provided by the Hellenic Statistical Authority were examined using Poisson, joinpoint regression and interrupted time series (ITS) analyses. SETTING: Greece. PARTICIPANTS: All infant deaths (n=4862) over the 13-year period, of which 87.2% were born to Greek mothers, and respective live births. MAIN OUTCOME MEASURES: Evolution of IMR (0-364 days), early (<7 days) neonatal mortality rate (ENMR), late (7-27 days) neonatal mortality rate (LNMR) and post neonatal (28-364 days) mortality rate (PNMR) trends, by maternal nationality, place of residence and Human Development Index (HDI). RESULTS: By Poisson regression, overall, during the study period, among infants of Greek mothers, IMR and PNMR declined significantly (-0.9%; 95% CI -1.7% to -0.1% and -1.6%; -3.0% to -0.2% annually, respectively), although differentially by place of residence (IMRurban: -2.1%; -2.9% to -1.3%, IMRrural: +10.6%; 7.6% to 13.6%). By contrast, among infants of non-Greek mothers, the low starting IMR/ENMR/LNMR/PNMR increased significantly (max ENMR:+12.5%; 8.6% to 16.5%) leading to a non-significant time-trend pattern overall in Greece. The inverse associations of HDI with IMR, ENMR and PNMR were restricted to Greek mothers' infants. Joinpoint regression analyses among Greek mothers' infants indicated non-significant increasing trends of IMR and ENMR following the crisis (+9.3%, 2012-2016, p=0.07 and +10.2%, 2011-2016, p=0.06, respectively). By contrast, the high (+17.1%; 8.1% to 26.9%, p=0.002) IMR increases among non-Greek infants were restricted to 2004-2011 and equalised to those of Greek mothers' infants thereafter. ITS analyses in preset years (2008, 2010, 2012) identified significantly increasing trends in IMR, LNMR and PNMR after 2012, and in ENMR after 2010, among Greek mothers' infants. CONCLUSIONS: HDI and rural residence were significantly associated with IMR. The strongly decreasing IMR trends among Greek-mothers' infants were stagnated after a lag time of ~4 years of crisis approximating the previously sharply increasing trends among non-Greeks
A controlled evaluation of a community injury prevention project in two Greek islands
Background. During the 20-month period September 1993 to April 1995, a
health education injury prevention programme focusing on home injuries
among the young (less than or equal to 18 years old) and elderly
(greater than or equal to 65 years old) on the Greek island of Naxos was
undertaken; its effectiveness was evaluated by comparing the subsequent
injury experience in sentinel population groups in Naxos as well as in
Spetses, another island of similar sociodemographic profile, where no
such intervention programme had been formally implemented.
Methods. On the island of Naxos an injury prevention campaign was
initially undertaken involving virtually all opinion leaders and
implemented through lectures, workshops and publicity in the local
media. The main intervention focused on 172 households on the island of
Naxos and was done by trained local collaborators who visited each
household weekly to provide injury prevention advice and assess home
safety. Similar visits were done by untrained collaborators in 177
households on the island of Spetses in order to assure collaboration of
household members in the comparative evaluation stage of the programme.
The process evaluation was based on ascertained changes of safety
features and attitudes in the participating households, whereas the
outcome evaluation was based on the incidence of injuries among members
of the participating households in the two islands over a period of 8.5
months (255 days).
Results. On the intervention island of Naxos there were statistically
significant improvements with respect to 11 of the 28 examined
variables, whereas on the island of Spetses, such improvement was only
noted for one variable. The age-adjusted incidence rate ratio of
injuries overall among the target groups, contrasting the intervention
and the control households was 0.85 with 90% confidence interval (CI)
:0.69-1.05. With respect to home accidents the corresponding ratio was
0.79 with 90% CI :0.60-1.04.
Conclusions. An intensive and focused injury prevention intervention had
only modest success when injuries themselves were the outcome variable
Are traffic injuries disproportionally more common among tourists in Greece? Struggling with incomplete data
Data concerning injury hazards among tourists are difficult to obtain
because estimates of person-time denominators are rarely available.
Existing sources are limited to enumeration of injured or killed persons
by nationality and type of injury and the analysis can only rely on
proportional indicators. Since 1995, the Regional Hospital in the
tourist island of Kerkyra (Corfu) has been covering all types of
accidents including road traffic injuries, in the context of the
Emergency Department Injury Surveillance System (EDISS). The catchment
area of this hospital practically coincides with the island population.
About 15% of all accidents are traffic-related among either permanent
residents or Greek tourists, but they represent 40% among tourists of
foreign nationalities. This is suggestive, but far from conclusive
evidence, that traffic injuries may be more common among foreign
tourists. There are indications that accidents among foreign tourists
overall are slightly more serious. Among Greek tourists, the ratio
between peak and non-peak period is similar for non-traffic injuries
(7.4) and traffic injuries (6.8), whereas among foreign tourists the
corresponding ratio is 9.2 for non traffic injuries and 15.0 for traffic
injuries. This pattern is difficult to explain in terms other than an
excess risk of traffic injuries among foreign tourists. (C) 1999

Characteristics of farm injuries in Greece.
OBJECTIVES: To assess the characteristics of occupational and leisure farm injuries in Greece. METHODOLOGY: During a five-year period (1996-2000), 4,326 unintentional farm injuries have been recorded by the Emergency Department Injury Surveillance System in Greece. Data concerning demographic variables, accident conditions, and injury characteristics were collected by in person interviews. The data were analyzed by simple cross-tabulation and hierarchical cluster analysis. RESULTS: Injuries from falls on the same level are mainly lower-limb fractures and occur during the winter among older women. Falls from higher level concern migrant workers, who also tend to suffer severe multiple injuries, including concussions, particularly during autumn. Injuries resulting from cutting and piercing instruments, as well as from machinery, are generally open wounds in the upper-limbs, suffered by young migrant workers. Head injuries resulting from striking against an object are more generally spread across socio-demographic variables. Overexertion is the dominant mechanism for dislocations and sprains in the lower limbs. Snake and insect bites are common among younger migrant workers during summer, and they affect the upper limbs during manual work close to the ground. Non-traffic injuries from vehicles are frequently severe, involving head concussion of generally young individuals. CONCLUSIONS: In Greece, farm injuries are frequently serious and require hospitalization. These injuries show distinct patterns among older women (lower-limb fractures), young individuals (non-traffic vehicle-related injuries) and migrant workers (injuries from cutting and piercing instruments, falls from high level, and bites). Prevention strategies should give priority to these population groups. These prevention strategies should include guidance for poorly educated workers, including migrants, enforcement of safety regulations concerning farming machinery, and discouragement of risky farming activities among elderly individuals, particularly women
How common is abuse in Greece? Studying cases with femoral fractures
Aims-To examine the extent of undiagnosed child abuse in Greece by
studying young children with femoral fractures, which may be associated
with abuse.
Methods-Fifty seven consecutive cases of children under 6 years of age
with femoral fracture were identified from the Emergency Department
Injury Surveillance System database. Controls were 4162 children with
other orthopaedic injuries from the same database.
Results-Whereas in the literature about one third of femoral injuries
among young children are attributed to child abuse, no child in the
studied series had been diagnosed or even investigated in this context.
Nevertheless, the pattern of occurrence of femoral injuries was
compatible with that of child abuse, in that patients were frequently
very young boys of low socioeconomic status, and the accident had
frequently occurred under poorly identified or implausible conditions at
time periods when most family members were crowded at home.
Conclusions-Epidemiological risk factors for child abuse characterise
femoral fractures in young children in Greece. It appears that child
abuse is present in this country as in most other cultures. There is a
clear need for refocusing medical personnel and hospital social services
so that the problem is revealed, quantified, and appropriately dealt
with
Home and leisure activities and childhood knee injuries
Aim: To assess the relative occurrence of non motor-vehicle knee
injuries and identify important clusters that can be targeted for
preventive interventions.
Methods: The study subjects covered 2167 children (0-14 years) who
suffered non motor-vehicle knee injuries out of 66 870 registered during
a three-year period in an established Emergency Department Injury
Surveillance System (EDISS). A more serious joint injury was identified
in 263 (12%) children, whereas the remaining 1904 children had only
soft tissue knee injuries.
Results: The incidence of non motor-vehicle knee injuries was estimated
at 6.5 per 1000 children-years. Both the incidence of knee injuries and
the male-to-female ratio increase with increasing age, reflecting the
gender and age pattern of physical activity. Three clusters were
identified: The first consisted of more serious knee injuries among
older children, frequently resulting after a fall from stairs or a
collision in school during winter months; the second cluster consisted
of rather minor knee injuries occurring mostly among younger girls at
home or in playgrounds, following a fall after stumbling or hit by an
object while playing, especially during the summer; the third cluster
comprised injuries among older boys, sustained mainly subsequent to
overexertion in a sports area.
Conclusion: Knee injuries tend to be more common among boys but more
serious among girls. More and less serious knee injuries tend to fall
into distinct clusters that could facilitate prioritisation of
preventive measures. (c) 2004 Elsevier Ltd. All rights reserved
