ABSTRACT
Background:Long-term exposure to low doses of ionizing radiation may affect cells and tissues and results in various adverse health effects. Objectives:In this study the purpose is to detect the blood cells count which reflects of the changes that may happen in bone marrow of X-ray technologists.Materials and Methods:The present study is conducted in Khartoum state hospitals during the year of 2011. The sample size was 95 male volunteers represented radiology technologists working in Khartoum state hospitals with age range 23-57 years.Technologists are classified according to duration of exposure.The samples are tested for hematology parameters by cell counter. Results:The mean value of leucocytes, neutrophil and lymphocyte count is significantly decreased (p<0.05) in X-ray technologists on duration of exposure between 10-15 years, while X-ray technologists on duration of exposure greater than15 years showed significant decrease (p<0.01) when compared to controls. However, no significant difference is observed in red blood count, hemoglobin, and mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, hematocrit and eosinophil + basophil count between the groups.Conclusion:Hematopoietic system of X-ray technologist is affected by long duration of low dose of X-ray exposure resulting in depression peripheral white blood cells count particularly that of neutrophil and lymphocyte.
ABSTRACT
El mielolipoma adrenal es un tumor benigno poco frecuente, compuesto de tejido adiposo maduro y elementos hematopoyéticos diversos. Estos tumores pueden localizarse en las glándulas adrenales aunque también pueden encontrarse en sitios extradrenales. Las manifestaciones clínicas son variadas tales como sangramientos digestivos, dolor abdominal en los flancos, masa abdominal palpable, hematuria, hemorragia retroperitoneal y pérdida de peso. Entre los métodos diagnósticos figuran el ultrasonido, la tomografía axial computarizada y la resonancia magnética. La resección quirúrgica es el tratamiento de elección, sobre todo cuando haya sintomatología o en tumores mayores de 4 cm, por el riesgo de ruptura espontánea con hemorragia retroperitoneal. Presentamos la historia clínica de una paciente de 42 años de edad con antecedentes de dolores en hipocondrio derecho de aproximadamente un año de evolución, la cual sufrió un cólico nefrítico que cedió con tratamiento médico. Posteriormente en la consulta externa, en el examen fisico, se constata una masa tumoral en hipocondrio derecho, la cual fue diagnosticada por ultrasonido y tomografía axial computarizada como un tumor adrenal. Se intervino la paciente y se confirma el diagnóstico. La evolución posoperatoria fue buena y la paciente continúa asintomática. El objetivo de este trabajo es presentar un nuevo caso de esta enfermedad, poco frecuente, la cual fue diagnosticada en una paciente de 42 años de edad y realizar una breve revisión de la literatura(AU)
Mielolipoma is a rare benign tumor of the adrenal gland, which is formed by mature adipose tissue and several hematopoietic elements. They are generally located in the adrenal glands, although they can occur in other sites. The clinical manifestations are varied such as gastrointestinal bleeding, abdominal pain in the flanks, abdominal mass, retroperitoneal hemorrhage, hematuria and loss of weight. Among the diagnosing methods are ultrasound, computerized axial tomography and magnetic imaging resonance. The surgical excision is the treatment of choice, mainly when symptoms are present or in case of over 4 cm tumors, because of the spontaneous rupture risk with retroperitoneal hemorrhage. The objective of this paper was to present a new case of this rare disease together with a brief literature review. A 42 years-old female with a history of abdominal pain located in the right upper quadrant of the abdomen, who suffered nephritic colic that was successfully treated. The physical exam at the outpatient service revealed a tumorous mass diagnosed as adrenal tumor by means of ultrasound and axial computerized tomography. She was operated on and the diagnosis was confirmed. Her postoperative recovery was good and the patient is still asymptomatic(AU)
