Staphylococcus aureus bacteremia in a secondary level Spanish hospital: clinical implications of high vancomycin MIC.

OBJECTIVE: One of the most controversial issues in recent years has been the clinical significance of high vancomycin MIC in Staphylococcus aureus bacteremia. The aim of this study was to elucidate the clinical implication that this parameter has in the staphylococcal bacteremia of a second level hospital. METHODS: Retrospective descriptive study between January 2014 and September 2016 with 138 records from the blood culture Severo Ochoa University Hospital registry. A total of 98 cases were finally analized. Microbiological analysis of vancomycin MIC was performed using micro dilution technique. RESULTS: The mean age was 71.4 ± 12.45 and 63.26% of the patients had a Charlson index ≥6. A 30.61% were carriers of a venous central catheter. The most frequent source was venous central catheter (26.53%). There were 14.24% metastatic events. Global mortality rate at 30 days was 25.51%. The 43.87% of strains had a vancomycin MIC ≥ 2 mg/L. High vancomycin MIC was significantly associated with persistent bacteremia (OR 3.12 [1.13-8.93]), maintaining this statistical significance in methicillin-resistant S. aureus (MRSA) group (p =0.001) but no in methicillin-susceptible S. aureus (MSSA) group (p = 0.13). Persistent bacteremia was also significantly related with permanent catheter carriers (OR 4.18 [1.38-12.61]), peripheric catheter source (OR 5.18 [1.13-8.93]) and metastatic complications (OR 3.82 [1.03- 12.81]). There was no significant association between high vancomycin MIC and mortality. CONCLUSIONS: High vancomycin MIC may be useful in daily clinical practice as a marker of poor clearance of S. aureus bacteremia, specially when is due to MRSA strains.

OBJECTIVES: To perform a situation analysis of the care provided by internal medicine units (IMUs) in Spain and to develop, based on this analysis, proposals for improving the quality of care in these units. MATERIAL AND METHODS: A descriptive, cross-sectional study of the IMUs of general acute care hospitals of the Spanish National Health System (SNHS), with data referring to 2013. The study variables were collected via an ad hoc questionnaire. RESULTS: Of the total 260hospitals identified in the SNHS, 142responses were obtained from 139hospitals throughout Spain, which represents 53.5% of the IMUs in the SNHS. The mean number of internists per IMU was 14±8, with a mean rate of 7.2±3.3 internists per 100,000 inhabitants. In 2013, the average number of hospital discharges from the IMU was 2,987±2,066, and those discharged by internists was 232±107. Sixty-one percent of the IMUs had implemented an interconsultation unit, and 41% had implemented a systematic care program for complex chronic patients. Thirty-three percent of the IMUs conducted multidisciplinary rounds, and 60% of these IMUs planned the discharge. CONCLUSIONS: The 2013 RECALMIN survey revealed a number of important aspects of the organisation, structure and management of IMUs. The remarkable variability in the indicators of structure, activity and management probably reflect significant differences in efficiency and productivity, which therefore provide significant room for improvement.

Linfadenitis histiocítica necrotizante de Kikuchi / Kikuchi's histiocytic necrotizing lymphadenitis

La linfadenitis histiocítica necrotizante (LHN) o enfermedad de Kikuchi-Fujimoto es una entidad anatomoclínica poco frecuente; afecta preferentemente a mujeres jóvenes e individuos de razas orientales y se caracteriza por fiebre, adenopatías preferentemente cervicales, afectación sistémica y, ocasionalmente, extraganglionar.Se presentan dos casos de LHN en mujeres jóvenes con afectación cutánea y en uno de los casos con meningitis linfocitaria.Se discuten los aspectos etiológicos, la relación de la LHN con las enfermedades colágeno-vasculares (fundamentalmente el lupus eritematoso sistémico [LES]), los problemas del diagnóstico anatomopatológico y las posibilidades terapéuticas (AU)

[Kikuchi's histiocytic necrotizing lymphadenitis]. / Linfadenitis histiocítica necrotizante de Kikuchi.

Necrotizing histiocytic lymphadenitis (NHL) or Kikuchi-Fujimoto disease is an infrequent seen clinicopathologic entity that affects most frequently young women and individuals of eastern races, and that is characterized by fever and adenopathies (basically cervical) and systemic disease even though occasional patients present extranodal disease. We present two young women with NHL and cutaneous affectation, and with lymphocytic meningitis in one of the patients. We discuss the etiology of NHL, the relation of NHL with collagen-vascular diseases (basically systemic erythematous lupus) the problem of the pathologic diagnosis, and the therapeutic possibilities in these patients.
