Patterns of Abundance and Host Specificity of Bat Ectoparasites in the Central Balkans

Bats are hosts to a number of ectoparasites-acarines (ticks, chiggers, other mites), bat flies, and fleas. Bat ectoparasites might have significant ecological and public health importance as they may be potential vectors of zoonotic agents. It is important to identify their distribution, diversity, and host-parasite associations. Bat ectoparasites in the central Balkans have been largely understudied. The present research was conducted in 45 localities at the territory of Bosnia and Herzegovina, former Yugoslav Republic of Macedonia, Montenegro, and Serbia. In total, 1,143 individuals of 18 species of bats have been examined for the presence and abundance of ectoparasite species during 3 yr of research. In total, 21 ectoparasite species have been identified: three species of ticks, seven species of mites (including one species of chigger), eight species of bat flies, and three species of fleas. In total, 80 host-parasite associations have been identified. The largest number of ectoparasites parasitized primarily only one host species. The highest total number of hosts was identified for ectoparasite species Ixodes vespertilionis Koch, Nycteribia schmidlii Schiner, and Spinturnix myoti Kolenati. The spinturnicid mite Spinturnix psi Kolenati was the most abundant ectoparasite species and together with Penicilidia dufouri Westwood the most widely distributed species of bat ectoparasite, being present at 21 localities in the central Balkans. The presented data include the first systematic records of patterns of prevalence, mean intensity, mean abundance, and host specificity for bat ectoparasites in the central Balkans.

Gender and morphogenetic variability of patients with spina bifida occulta and spina bifida aperta: prospective population-genetic study

BACKGROUND

Aim of our study was to evaluate degree of genetic homozygosity in male and female gender of spina bifida (SB) occulta and SB aperta patients.

PATIENTS AND METHODS

We evaluated 95 patients with SB occulta and 51 with SB aperta. Degree of genetic homozygosity was evaluated by direct observation of 15 homozygously recessive characteristics (HRC) by HRC-test separately for SB occulta and SB aperta participants. Additionally 370 individuals without SB from Serbia were randomly selected and evaluated as control group. Male and female gender was separately evaluated for assessing degree of genetic homozygosity.

RESULTS

There was no significant difference in mean values of HRC between male and female gender in control group (male gender -3.9±1.2, female gender -4.0±1.4, z=0.39; p>0.05), SB occulta (male gender -4.1±1.5, female gender -4.7±1.4, z=1.87, p>0.05) and SB aperta patients (male gender -4.3±1.6, female gender -4.5±1.4, z=0.66, p>0.05), while there was significantly increased recessive homozygosity in female SB occulta group versus control female group (Females: SB occulta -4.7±1.4, Control group -4.0±1.4, z=3.16, p<0.01) and female SB aperta group versus control female group (Females: SB aperta -4.5±1.4, Control group -4.0±1.4, z=2.05, p<0.05).

CONCLUSION

There is increased recessive homozygosity in tested female SB occulta and female SB aperta individuals versus SB male participants and significantly increased recessive homozygosity in female groups of SB patients versus control female group. These findings could lead to the possible assumption that different genes in different degree might be expressed in SB occulta and SB aperta patients.

Double innominate osteotomy and the Smith-Petersen technique in the treatment of developmental hip disorder

PURPOSE

The purpose of our study was to present results of different surgical orthopaedic approaches in the treatment of children with developmental hip disorder.

MATERIAL AND METHODS

At the University Childrens Hospital in Belgrade, 21 young adults diagnosed with developmental hip disorder were treated with double osteotomy and with a modified Smith-Peterson approach during a period of 10 years, from 1997 to 2007. All patients were clinically and radiographically evaluated.

RESULTS

We were successful with 23 hips in 20 patients, since some patients underwent surgery of both hips. The evaluation of improvement was done according to the Merle d'Aubigne and Postel system which indicated very satisfied outcome in five patients, satisfied in 8, fair in 7 and poor in one patient.

CONCLUSIONS

In this paper we discuss the advantages and disadvantages of double osteotomy procedures compared with others that are used in the correction of developmental hip disorder. The best solution is adequate and timely diagnosis with proper correction of the deformity.

Congenital muscular torticollis in children: distribution, treatment duration and out come

AIM

The aim of the study was to evaluate the proportion of left and right congenital muscular torticollis (CMT) in both genders and age groups of the patients as well as to evaluate the duration of physical therapy and treatment outcome in observed population.

METHODS

In our study, 980 children with CMT without hematoma were treated at University children's Hospital of Belgrade (Serbia). They were divided into 2 groups: group with left torticollis and group with right torticollis. Boys and girls were separately evaluated. Patients were classified into 5 age groups: group of children less than one month of life, group above one to 3 months, group above 3 months to 6 months, group above 6 months to 12 months and group of children above 12 months of life. Optimal time for physical therapy was analyzed in every age group.

RESULTS

We diagnosed 496 torticollis in boys and 484 torticollis in girls. There were 458 children with left torticollis and 522 children with right torticollis. In group of children less than one month of life median duration of physical therapy was 1.5+/-0.3 months, in group above one to 3 months of life 5.9+/-0.6, in group above 3 to 6 months 7.2+/-0.6, in group above 6 to 12 months 9.8+/-0.6 and in group of children above 12 months of life 10.3+/-0.8 months.

CONCLUSION

Right torticollis is frequent in both genders and age groups. Younger children have lower treatment duration and better treatment outcome. Boys have longer treatment duration and not significantly better treatment outcome.

Physical therapy of non-neurogenic voiding dysfunction in children with occult spinal dysraphism

BACKGROUND

In children with occult spinal dysraphism one of the symptoms is disbalance in bladder emptying and filling. Goal of our study was to estimate the correlation of medicamentous treatment alone and combined medicamentous and physical treatment in patients that are diagnosed with occult spinal dysraphism with non-neurogenic bladder dysphunction.

METHODS

We evaluated 69 patients aged from 4 to 12 years treated at the University children's Hospital in Belgrade during 2005-2008 years period. In the first group of 29 patients only medicamentous therapy was implemented. In the second group of 40 patients combined medicamentous and physical therapy were applied. Physical therapy methods that were used included: transcutaneal electric nerve stimulation and exponential current. We monitored daily enuresis, enuresis nocturna, urgency and frequency. Urodynamic evaluation included: bladder capacity, onset of unstable contractions, residual urine and detrusor sphincter dyssynergia.

RESULTS

Statistical analysis showed that there is significant improvement (p < 0.001) in all evaluated symptoms after 6 months and for urgency there was significant improvement (p < 0.05) after 3 months from the beginning of the treatment with combined therapy. Our study pointed out significant improvement in the group treated with combined therapy for detrusor sphincter dyssynergia and unstable contractions after 3 months while after 6 months from the beginning of the treatment there was significant improvement (p < 0.001) for all urodynamic parameters.

CONCLUSIONS

Combined medicamentous and physical treatment is more beneficial for patients with non-neurogenic bladder instead of medicamentous treatment alone (Tab. 2, Ref. 11).

Orthopaedic patterns of retroperitoneal tumors in pediatric population

The paper presents three children of various ages with tumors of different histology localized in the retroperitoneum. The children underwent investigation as orthopedic cases at the Orthopedic Department of the Belgrade University Childrens' Hospital. All children had orthopedic symptoms and several similar clinical findings: high or increased red blood cell (RBC) sedimentation, increased lactate dehydrogenase (LDH) and hypochromic anemia. Retroperitoneal tumors were diagnosed by echosonography. Further investigations were targeted towards histological verification and treatment protocol for retroperitoneal tumor. Since the children were presented chronologically to the deparmtent, diagnosis was reached more rapidly. It is our aim to draw attention to the possibility that various retroperitoneal tumors can be presented as orthopedic diseases. If symptomatology of retroperitoneal tumors is suspected and particularly in insufficiently clear cases, one should always perform echsonography of the retroperitoneum as a non-agressive, simple, readily available and reliable diagnostic method. This reduces examination time, direction of patients to further treatment according to pathology and also in reduction of risk both for patient and orthopedic surgeon who normally are presented with such diseases (Fig. 2, Ref. 10).

Rehabilitation protocols in children with corrected congenital heart defects due to the presence of pulmonary complications

BACKGROUND

The Aim of our study was to present early rehabilitation protocols for children with and without pulmonary complications after the correction of congenital heart defects and to estimate the optimal time for the initiation of early rehabilitation in both groups of children.

METHODS

In our study, 176 children treated at the University Children's Hospital in Belgrade were evaluated during the period 2003-2007. All patients were children with the corrected congenital heart defects from birth to 12 months of life.

RESULTS

In the group of patients without pulmonary complications we administered 3.64 +/- 1.02 exercises and in the group with present pulmonary complications we implemented 2.71 +/- 0.79 exercises. The optimal time for the initiation of early rehabilitation is 1.54 +/- 1.37 days for the group of children that did not have pulmonary complications, but for the other group the period was longer: 2.27 +/- 1.68 days.

DISCUSSIONS

The optimal number of exercises in children younger than one year of life is from 2 to 4 and the early rehabilitation should start as soon as possible. A desirable time for beginning of such program is within 24 to 48 hours post surgery but it cannot be limited to this interval due to possible complications stating that every child should have an individual approach (Tab. 3, Ref. 14).
