Bone scintigraphy and radiolabeled white blood cell scintigraphy for the diagnosis of mandibular osteomyelitis.

The aim of this study was to evaluate the diagnostic efficacy of bone scintigraphy (BS) and radiolabeled white blood cell scintigraphy (WBCS) in detecting septic activity in the flat bones of the jaw. A retrospective analysis was conducted using 38 studies of combined BS plus WBCS: 33 of them 3-phase BS and 36 of them 2-phase WBCS. These studies were performed on 34 patients, 19 women and 15 men with a mean age of 56 years (22-79), who presented with suspected mandibular osteomyelitis, either acute or chronic exacerbation. The results were compared with histologic findings (55%) or with a minimum clinical/radiologic follow-up of 6 months (average, 21 months), when biopsy results were not available. BS showed a sensitivity of 100%, a specificity of 6.7%, a positive predictive value of 62%, and a negative predictive value of 100%. For WBCS, the corresponding values were as follows: 73.7%, 78.6%, 82%, and 69%. Accuracy was 63.2% for BS and 94.7% for WBCS. WBCS has proven to be a useful test for detecting septic activity in the jaw bone, being more effective than BS alone, which under certain circumstances, can return a very high false-positive rate.

Complicaciones de la cirugía endoscópica nasosinusal en un programa de entrenamiento de residentes / Complications of endoscopic sinus surgery in a residency training program

Introducción: La cirugía endoscopica nasosinusal presenta una serie de complicaciones que varían en función de la técnica usada y la experiencia del cirujano. Esta técnica requiere una curva de aprendizaje la cual se debe ir desarrollando a lo largo del programa de formación del residente. Métodos: Estudio descriptivo y retrospectivo, se realizó una revisión de las historias clínicas de 192 pacientes intervenidos de cirugía endoscopica por poliposis nasosinusal, todas estas cirugías fueron realizadas por residentes de nuestro departamento, entre enero de 2002 y enero de 2008. Se describe el sexo, edad, grado de poliposis, complicaciones mayores y menores. Todos estos procedimientos fueron realizados por residentes de 3.er y 4.° año bajo la supervisión de un especialista. Resultados: De 192 pacientes, 127 (66,14) eran varones y 65 (33,85%) mujeres, con edades comprendidas entre 24 y 78 años, con una media de edad de 49 años. El grado de poliposis por endoscopia era: grado i 19 (9,8%), grado ii 55 (28,6%) y grado iii 118 (61,45%). Ocurrieron 44 (22,9%) complicaciones totales, 40 (20,8%) menores y 4 (2,08%) mayores. La complicación menor mas frecuente fue la sinequia en 21 casos (10,93%) seguida de sangrado sin necesidad de transfusión en 12 (6,25%) pacientes. La complicación mayor fue ruptura de la lamina papiracea en 4 (2,08%) pacientes. No se presentó ningún caso de ceguera, rinolicuorrea, o muerte. Conclusión: La cirugía endoscopica nasosinusal en un programa de entrenamiento de residentes es un procedimiento relativamente seguro especialmente cuando se realiza bajo la supervisión de un especialista (AU)

Introduction: Endoscopic sinus surgery presents a series of complications that can vary depending on the technique used and the surgeon's experience. This technique needs a learning curve, which must be developed during the residence training program. Methods: Descriptive and retrospective study, reviewing the medical records of endoscopic sinus surgery for nasal polyps of 192 patients who had undergone operations performed by residents at our department between January 2002 and January 2008. Patient sex, age, affectation scale and minor and major complications were described. All these procedures were performed by 3rd or 4th-year residents under the supervision of a faculty member. Results: Of the 192 patients, 127 (66.14%) were male and 65 (33.85%) female, aged between 24 and 78 years old, with a mean age of 49 years old. Nasal endoscopy revealed polyposis of grade I, 19 (9.8%) cases; grade II, 55 (28.6%); and grade III, 118 (61.45%). There were 44 (22.9%) total complications, 40 (20.8%) minor and 4 (2.08%) major complications. The most common minor complication was synechia formation in 21 (10.93%) cases, followed by bleeding without need for transfusion in 12 (6.25%). The major complication was a breach of the lamina papyracea in 4 patients (2.08%). There were no cases of blindness, cerebrospinal fluid rhinorrhea, or death. Conclusions: Endoscopic sinus surgery in an otolaryngology residency training program is a relatively safe procedure, especially when performed under faculty supervision (AU)
