Public health Survey of
diagnostic paediatric radiology and the resulted
collective effective dose (2000 y) Cornelia
Diaconescu, Olga Iacob
Abstract. The purpose of our study was to update the annual frequency of x-ray
examinations and the pattern of paediatric
radiology in 2000 year. Also, to assess in terms of effective dose the
magnitude of pediatric patient exposure during conventional x-ray
examinations, selected by their high frequencies or their relatively high
doses delivered to patient. The annual effective doses from all medical
examinations for the average pediatric patients are as follows: 0.85 msv for 0 year old, 0.53 msv
for 1 year old, 0.56 msv for 5 year old, 0.72 msv for 10 year old and 0.74 msv
for 15 year old. The resulting annual collective effective dose was evaluated
at 872 mansv, with the largest contribution of
pelvis and hip examinations. However, this value could be much larger because
the ct annual use increased in 2000 y up to 3.1% of total examinations from a
negligible one of 0.1% in previous survey. Key words: paediatric radiology, X-ray examinations, effective dose, collective effective dose Ü FULL TEXT.PDF The map of indoor radon concentrations in northeastern Romania C. Grecea, Olga Iacob Abstract. The radon concentrations have

TEXT.PDF Drug expenditure in a tertiary hospital Odetta Duma Abstract. In conditions of
increasing health care costs and reduced rate of economic growth, hospitals are
the main consumers within the health system. The present paper represents a
two years (2000-2001) detailed analysis of drug expenditure per unit of
activity (bed, hospital day and inpatient) in a tertiary hospital with
special departments of nephrology and urology. Each hospital department
participated in an internal comparison and some of these data were used in a
comparison with other hospitals of the same level from Key words: tertiary hospital, drug expenditure, unit

TEXT.PDF Prematurity and low weight at birth:
risk factors for defects of enamel development Marinela Păsăreanu Abstract. The aim
of this study was to determine the prevalence of enamel defects in two school communities
using SCOTS Index and to correlate the results to
two potential risk factors: prematurity and low weight at
birth. Mixed dentition status was assessed at 121 children and the prevalence highest value of enamel defects was 9%. A significantly strong prevalence (p< 0.001)
of the defects of enamel development and of the analyzed
potential risk factors was noticed.
Further studies are needed to clarify
whether achieving near optimum intra-uterine
mineral retention would decrease the prevalence of subsequent enamel defects in infants born prematurely. Key words:

exposure among manufacturing workers Brigitte Scutaru, Carmen Cozmei,
V. Cazuc, Doina Popa, B. Hock Abstract.
This study assesses the feasibility of an enzyme-linked immunosorbent assay (ELISA) for the determination of atrazine in serum samples collected from twenty workers engaged in technical atrazine dust formulating and bagging processes. An assay was developed
with the middle of the test (IC 50) at 0.08±0.02 mg/L, a limit of detection of about 100 ng/L and the
coefficients of variation
up to 8 %. Serum atrazine levels were interpreted
taking into account the airborne
concentrations of atrazine
in the workplace atmosphere. The immunoenzymatic method itself is convenient, inexpensive and easy to use.
It was, therefore, concluded that serum sampling
of atrazine exposure among worker populations is a feasible biomonitoring method. Key words:

detection and occupational exposure to atrazine
Carmen Cozmei,

Carasevici Abstract. The aims of this study were to
evaluate the influence of
the herbicide atrazine on peripheral
mononuclear cells on occupationally exposed individuals in terms of their possible DNA – damage effect and to determine whether p53 protein can serve as a biomarker for this exposure or not. 19 workers employed by “Chimcomplex” Company – Borzesti (Romania) in the atrazine production unit were examined and p53 immunocytochemistry was performed. The results showed that 68.4% of the workers were positive for p53 protein and these data were interpreted as a proof indicating that immunocytochemical detection of the p53 protein expression is a feasible means for monitoring atrazine exposure.

Romaniuc, Anca Nistor, Cecilia Durnea Abstract OBJECTIVE: The
periodical evaluation of the population specific protection against the
diseases included in the National Immunization Program (NIP) is necessary in
view of the strengthening strategies. MATERIAL AND METHODS: The study
was performed in 2001 y on a representative sample of 714 children aged less
than 5 years old. The determination of antibody levels was made through the
indirect ELISA (Diasorin kits) taking 0.1 IU/ml as
basic level for diphteria and tetanus antitoxine, 10 IU/l for the HBs
antibodies, and higher than 40 AU/ml for measles and pertussis
antibodies. RESULTS: Tetanus
sero-protection was found in 96% of children (95%
CI: 94.6–97.4) with an average geometrical mean of tetanus antitoxine antibodies of 1.49 IU/ml. The protection level
of the diphteria antitoxine
antibodies was about 10% lower than the level of antitetanus
sero-protection of 87.4% (95% CI: 86.1-88.7). The
children vaccinated with DTP3 have a medium level of seroprotection,
while those who received 4 doses of vaccine have 91.8%. The Bordetella pertussis antibodies
were present at a protector level in 76.1% children (95% CI: 72.9-79.2). The humoral antimeasles immunity
reaches an average of 55.6% protected children (95% CI: 52.1-59.2) for a level
of seropositive values of 62%. The percentage of
the children protected against hepatitis B virus (HBV) infection had an
average value of 59.5% (95% CI: 57.1-63.1) while the seropositive
value was estimated to be 71.9%. CONCLUSIONS: The specific immunity to
tetanus in the children aged less than 5 years corresponds to the goal of the
National Immunization Program, but it is lower for diphteria,
measles and HBV indicating susceptibility to these diseases. Key words: vaccination, prevalence, postvaccinal
immunity Ü FULL TEXT.PDF Study on specific IgG avidity as a tool for recent primary Toxoplasma gondii infection diagnosis

Lovin Abstract. Toxoplasma gondii, protozoan with worldwide distribution, can
cause life-threatening disease for the unborn child when maternal infection
is acquired during pregnancy. The accurate dating of maternal toxoplasmosis
is essential in order to assess the risk of subsequent congenital infection.

Dan Mancaş, Diana Diaconu Abstract. This study aimed to estimate the
hazards associated with the use of chlorination in a water-work where some
episodes of chemical pollution were recorded in the recent years. The methodological
approach consisted in twice a year sampling of large volumes of raw and
chlorinated water then processed to concentrate the non-volatile organic
chemicals. The analyses of water samples indicated high levels of organic
matter in chlorinated water, up to 21.17g/l. A complex mixture of chemicals
in each of both extracts has been identified by GC-MS technique. Higher
levels of 3-chloro-4(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX), a strong mutagen compound, in chlorinated
water extract in comparison with the corresponding raw water extract of
samples of 2000 year summer have been measured for the first time in Romania.
