RESUMEN
Se presenta el caso de una paciente de 39 años con antecedentes personales de pustulosis palmoplantar de varios años de evolución y dolores ocasionales en la pared anterior del tórax, columna lumbar y ambas sacroilíacas. Acude por dolor esternoclavicular y en los primeros arcos costales izquierdos con tumefacción, palpación dolorosa y febrícula. Se diagnostica como síndrome de SAPHO basándonos en los hallazgos clínicos, radiológicos (TC), gammagráficos y manifestaciones cutáneas. La gammagrafía ósea es una prueba diagnóstica sensible y precoz para este síndrome que proporciona la ventaja de obtener imagen del cuerpo completo. (AU)

We present the case of a 39 year old woman with a several year long history of palmoplantar pustulosis and occasional pain in the anterior wall of the thorax, lumbar spine and both sacroiliac joints. As a consequence of low grade fever, severe sternoclavicular pain and discomfort and swelling in the first left rib arches, the patient was admitted to hospital. Based on the clinical, radiologic, scintigraphic and cutaneous findings, the SAPHO syndrome was diagnosed. Bone scintigraphy is an accurate and early diagnostic test for this syndrome which also provides the advantage of being able to obtain a whole body scan.

1. Studies with Single Photon Emission Computed Tomography (SPECT) in schizophrenia research have utilized different approaches to normalization of data, such as cerebellar ratio and whole brain ratio methods, leading to conflicting findings. 2. The authors compared these two methods to test the hypofrontality hypothesis of schizophrenia. 3. Eighteen chronic and medicated DSM-IV schizophrenic patients and 10 healthy controls underwent two SPECT examinations using 99mTc HMPAO as a tracer at baseline and during frontal activation while applying the Wisconsin Card Sorting Test. 4. The hypofrontality hypothesis was supported with both indexes of relative perfusion, although the whole brain ratio method appeared to be more reliable and specific than the cerebellar ratio method. 5. Further studies are required to confirm these preliminary results on the specificity and sensitivity of both methods.
