INTRODUCTION AND OBJECTIVES: A study is made of the clinical repercussions of occult metastases-micrometastases (MMs+)-or isolated tumour cells (ITCs+) in the lymph nodes of patients with stage IIA and IIB colon adenocarcinoma initially considered as corresponding to N0. MATERIAL AND METHODS: A retrospective study of 39 patients with stage IIA and IIB (T3-T4 N0 M0) colon adenocarcinoma, subjected to similar surgical and adjuvant chemotherapy treatment, with long and careful follow-up (minimum: 5 years, mean: 81.7 months) was performed on their previously resected lymph nodes, with the aid of new histological and immunohistochemical (cytokeratin) sections, in order to detect MMs or ITCs. Disease-free survival (DFS) and global survival (GS) in the two groups (patients with MMs+ or ITCs+ vs. patients without MMs or ITCs) were compared at 5 years based on the corresponding Kaplan-Meier survival curves, with the Breslow test. RESULTS: A total of 382 lymph nodes from the 39 patients (mean: 9.8; standard deviation: 6.09) were revised. MMs+ were detected in 2 cases and ITCs+ in 2 more cases on the Cytokeratin study. GS of the whole series at 5 years was 89.74% (35 patients alive) with a DFS at 5 years of 79.49% (31 patients free of disease), but the 2 cases with MMs+ were dead at 5 years, with high statistical differences between both groups (MMs+/MMs-) (p<0.0001). When comparing the group of MMs+/ITCs+ patients and the group of MM-/ITCs- patients, the DFS and GS times at 5 years were higher in the MMs-/ITCs- group (p=0.0692 and p=0.006 respectively). CONCLUSIONS: Although the incidence of MMs+ or ITCs+ in the examined lymph nodes was low, the presence of MMs is related to a dramatic reduction in GS and DFS at 5 years. We encourage a detailed histological study of lymph nodes resected in patients with deep penetrating colon tumours in order to assure a pN0 status (AU)

BACKGROUND: There are a lot of controversies related to the diagnostic and therapeutic management of Whipple s disease. PATIENTS: We present 4 cases of Whipple's disease, collected from the Gastroenterology Service of the Hospital Ramon y Cajal, from Madrid. RESULTS: The average age was 69. The first symptoms were in order of frequency, arthralgias, loss of weight, arthritis, diarrhoea, fever, epigastric pain and neurologic symptoms. Three were treated with trimethoprim-sulphamethoxazol and one with cefixime. There were no recurrences. CONCLUSIONS: The endoscopic appearance of the duodenum is fundamental for the suspicion of the disease. The initial parenteral treatment may consist of ceftriaxone and try to avoid using streptomycine because of its toxicity, followed by oral trimethoprim-sulphamethoxazol. As an alternative to the latter, cefixime is usually effective. The typical findings of the duodenum biopsy can persist several months or years after finishing the treatment, decreasing the value of endoscopic pursuit after treatment.

Fundamento: Existen muchas controversias relacionadas con el manejo diagnóstico y terapéutico de la enfermedad de Whipple. Pacientes: Se presentan cuatro casos de enfermedad de Whipple, recogidos del Servicio de Gastroenterología del Hospital Ramón y Cajal de Madrid. La edad media fue 69 años. Los síntomas de presentación fueron en orden de frecuencia artralgias, pérdida de peso, artritis, diarrea, fiebre, dolor epigástrico y síntomas neurológicos. Tres fueron tratados con trimetroprim-sulfametoxazol y uno con cefixima. No hubo recidivas. Conclusiones: El aspecto endoscópico del duodeno es decisivo para la sospecha de la enfermedad. El tratamiento inicial parenteral de la enfermedad debe realizarse con ceftriaxona e intentar evitar la estreptomicina por su toxicidad, seguido del trimetroprim-sulfametoxazol oral. Como alternativa la cefixima parece eficaz. Los hallazgos típicos de la biopsia pueden persistir meses y años después de finalizado el tratamiento, lo cual resta valor al seguimiento endoscópico de los pacientes tras el tratamiento (AU)
