Central region morphometry in a child brain; Age and gender differences
Background: Data on central region morphometry of a child brain is important not only in terms of providing us with information about central region anatomy of the brain but also in terms of the help of this information for the plans to be applied in neurosurgery.Objective: In the present study, central region morphometry of a child brain in mid.sagittal MR images was analyzed in age and gender groups.Materials and Methods: Different points determined previously, commissura posterior (PC) and the distances between cerebral cortex point (VCS) vertical to commissura anterior. commissura posterior line, sulcus centralis (CS), sulcus marginalis (MS), and the angle (α) between CS-PC-MS were determined and measured together with difference of gender in three different age groups (aged 6.9, 10.13, and 14.17).Results: Central region measures of the brains of boys aged 6.17 are higher than girls except for MS.PC distance. While VCS.PC, CS.PC, and MS-PC measures display a significant difference in the girls aged 14.17 when compared to the other age groups of 6.9 and 10.13 (P < 0.05), angle α is not significantly different in age and gender groups (P > 0.05). However, while VCS-PC, CS-PC and MS-PC distances show a significant increase in girls beginning from the age of 14, this increase is limited in boys.Conclusion: Morphometric differences observed in different age groups in boys and girls shall contribute our evaluation of the alterations in brain development in both of genders and shall be useful in preparation of surgical operation plans to be applied to the central region.Key words: Brain, central region, child, morphometry, magnetic resonance Imagin
Determination of cerebellar volume in children and adolescents with magnetic resonance images
Recent studies show that the cerebellum contributes to higher cognitive functions
as well as its role on motor system. It is thought that higher cognitive
functions continue to develop during childhood and adolescence; therefore,
cerebellum develops significantly during these periods. For that reason, this
study was carried out in order to determine cerebellar volumes of 90 healthy
individuals (40 males, 50 females) aged between 6 and 17 years according to
their gender. The individuals were divided into three age groups of 6–9, 10–
–13, and 14–17 years, and their cerebellar volumes were found by means of
stereological methods using their magnetic resonance images. The cerebellar
volumes found were compared among the groups without discriminating genders,
among groups according to gender, and again according to gender within
each age group. The general average cerebellar volume of the age group
10–13 years was significantly higher than the other two age groups (p < 0.05).
When the groups were compared according to gender, there was no important
difference between the groups in women (p > 0.05); as for men, cerebellar
volume only in the age group 10–13 years was significantly higher than that
in age group 6–9 (p < 0.05). When cerebellar volume for ages 6–17 years was
compared according to gender (without dividing into age group) there was no
significant difference between men and women (p > 0.05). It was seen that
the cerebellum develops from childhood to adolescence, and reaches peak
levels between the ages 10–13 years for both genders
Evaluation of the length and angulation of the styloid process in the patient with pre-diagnosis of Eagle syndrome
Clinical symptoms caused by the elongated styloid process (SP) or calcified stylohyoid
ligament were first described by W. Eagle and they are now known as Eagle syndrome
(ES). Normal length of SP was stated by Eagle as 2.5 cm. The objective of this
study was to determine and discuss the length of SP and medial angulation degree
with computed tomography (CT), which is an affective modality in the identification
of ES, and a comparison with related studies.
Three-dimensional (3D) images obtained from the axial CT scans of 22 cases (11 males
and 11 females) aged between 24 and 80 years, who referred to Cumhuriyet
University Hospital, Department of Radiology for multi slice CT with the pre-diagnosis
of ES, were used. Lengths of the SP and medial angulations were measured on
the obtained images. Inter- and intra-group comparisons were carried out using
Wilcoxan and Mann-Whitney U tests.
The mean length of the SP was found as 4.1 ± 1.1 cm. When inter- and intra-group
lengths of the right and left SP were compared, the difference was not significant
(p > 0.05). The mean medial angulation of the SP was found as 67.5 ± 5.1°. There
was a significant difference found between the right side medial angulation and left
side medial angulation in all persons (p < 0.05).
Lengths of the right and left SP of the patients with pre-diagnosis of ES were close to
each other. However, the right-side angulation was observed to be smaller than the
left medial angulation in all the patients. Similarly, right side medial angulation of the
females was smaller than the left side medial angulation, but this difference was
absent in the males. Eagle syndrome should be kept in mind in patients with a sore
throat radiating to the ears with swallowing and an observed non-compliance between
the complaints such as feeling a foreign body in the throat and facial pain,
and physical examination of those who do not have a response to long-term medical
therapy should be performed. (Folia Morphol 2011; 70, 4: 295–299
Nosocomial bloodstream infections with Burkholderia stabilis
Burkholderia stabilis was grown from blood cultures of seven patients presenting with signs and symptoms of septicaemia in the intensive care unit at Mersin University Hospital, Mersin, Turkey between July and October 2002. Four patients had one B. stabilis-positive blood culture, two patients had two, and one patient had four. Isolates from six of seven patients had the same resistotype and random amplified polymorphic DNA analysis type. Despite treatment with ciprofloxacin and imipenem, to which the strains were susceptible, all patients died one to eight days after isolation of B. stabilis from their blood. B. stabilis should be regarded as an opportunistic pathogen that may cause nosocomial bloodstream infections. (C) 2004 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved
