ABSTRACT
SUMMARY OBJECTIVE: The aim of this study was to examine the changes on the Purkinje cells in the cerebella of male rat pups born to pregnant dams that were exposed to an electromagnetic field in the prenatal period. METHODS: The first stage of the study involved 12 Sprague-Dawley rats, 6 male and 6 female, weighing between 180 and 250 g. The female rats in the experimental group were exposed to a 900-MHz electromagnetic field for 1 h at the same time every day, and no procedure was performed on the control group. Following pregnancy, six male pups from each group were divided into experimental and control groups without any procedure on the pups. After 2 months, they were sacrificed and their cerebella were removed. Histopathologically, following routine processing and fixation procedures, the cerebella were embedded in the tissue blocks. The sections taken from these blocks were stained with cresyl violet. The Purkinje cells in the cerebella were then counted on sections using the optical dissector method on an image analysis system. RESULTS: The estimation of number of the Purkinje cells in the groups revealed more cells in rats in the control group than in the experimental group. Histopathologically, Purkinje cells exhibited a normal morphological structure in the control group, while the cells in the experimental group showed damage. CONCLUSIONS: It might be asserted that the exposure of mothers to an electromagnetic field in the prenatal period may affect the development of Purkinje cells in the pup cerebella.
ABSTRACT
SUMMARY: Heel spur is an osteophytic protrusion larger than 2 mm that lies just anterior to the tuberosity of the calcaneus. Heel spur can be of two types: plantar heel spur and dorsal heel spur. The aim of this study was to evaluate the relationship between the heel spurs incidence with age, sex and side. A total of 2000 bilateral radiographs of 1000 patients (518 men and 482 women) aged 20-93 years who applied to Terme state hospital, Samsun, Turkey due to trauma were examined. Patients were grouped into 10 year age ranges (20-29 years; 30-39 years; 40-49 years; 50-59 years; 60-69 years and over 70 years). The incidences of plantar heel spur, dorsal heel spur, and both were evaluated according to age, sex and side relations. Plantar or dorsal heel spurs were detected in 32.6 % (326 patients) of the patients. The incidences of plantar heel spur, dorsal heel spur, plantar and dorsal heel spur were 26.0 %, 16.9 %, and 10.3 % respectively. According to sex, the incidence of plantar heel spur was higher in women in all age groups. Although the incidence of dorsal heel spur was higher in men in the 6th decade, it was more common in women in other age groups. The incidence of plantar heel spur was 2.615 times higher in the right foot and 2.810 times higher in the left foot in women. As the age increased, the risk of plantar heel spur increased 1.060 times in the right foot and 1.061 times in the left foot. The incidence of dorsal heel spur was 1.510 times higher in the right foot and 1.715 times higher in the left foot in women. As the age increased, the incidence of dorsal heel spur increased in both feet and this increase was 1.055 times in both feet.
RESUMEN: El espolón calcáneo es una protuberancia osteofítica de más de 2 mm que se encuentra por delante de la tuberosidad del calcáneo. El espolón calcáneo puede ser de dos tipos: espolón calcáneo plantar y espolón calcáneo dorsal. El objetivo de este estudio fue evaluar la relación entre la incidencia de espolón calcáneo con la edad, el sexo y el lado. Se examinaron un total de 2000 radiografías bilaterales de 1000 pacientes (518 hombres y 482 mujeres) de 20 a 93 años de edad que fueron solicitadas en el hospital estatal de Terme, Samsun, Turquía debido a un traumatismo. Los pacientes se agruparon en rangos de edad de 10 años (20-29 años; 30-39 años; 40-49 años; 50-59 años; 60-69 años y mayores de 70 años). Las incidencias de espolón calcáneo plantar, espolón calcáneo dorsal y ambos se evaluaron de acuerdo con la edad, el sexo y lados. Se detectaron espolones calcáneos plantares o dorsales en el 32,6 % (326 pacientes) de los pacientes. Las incidencias de espolón calcáneo plantar, espolón calcáneo dorsal, espolón calcáneo plantar y dorsal fueron del 26 %, 16,9 % y 10,3 %, respectivamente. Según el sexo, la incidencia de espolón calcáneo plantar fue mayor en mujeres en todos los grupos de edad. Aunque la incidencia del espolón calcáneo dorsal fue mayor en hombres en la sexta década, era más común en mujeres en otros grupos de edad. La incidencia de espolón calcáneo plantar fue 2,6 veces mayor en el pie derecho y 2,8 veces mayor en el pie izquierdo en mujeres. A medida que aumentaba la edad, el riesgo de espolón calcáneo plantar aumentaba 1,06 veces en el pie derecho y 1,061 veces en el pie izquierdo. La incidencia de espolón calcáneo dorsal fue 1,510 veces mayor en el pie derecho y 1,715 veces mayor en el pie izquierdo en mujeres. A medida que aumentaba la edad, la incidencia de espolón calcáneo dorsal aumentaba en ambos pies y este aumento era de 1,055 veces en ambos pies.
