ABSTRACT

To improve culture yield in cases of possible septic arthritis; we compared culture of joint fluid aspirates on conventional agar-based media to culture in Bactec 9240 Peds/Plus F blood culture bottles with and without the addition of fastidious organism supplement (FOS). Over a period of 21 months; we analysed 123 synovial fluid samples and isolated 20 pathogens. The Bactec methods proved superior by yielding more pathogens than the conventional culture method (p=0.074). However; this method also yielded more contaminants within the first three days of incubation (p=0.027). All contaminants detected after three days of incubation were the result of overgrowth on conventional method agar plates. The Bactec methods provided clinicians with a positive pathogen result one day earlier than the conventional counterpart (p=0.001). Four isolates of Neisseria gonorrhoeae were only cultured with the Bactec method. No significant benefit was demonstrated by supplementing blood culture bottles with FOS. We recommend that whenever infection by fastidious organisms is suspected; synovial fluid aspirates should be cultured using automated blood culture systems to increase the culture yield and to decrease the time to detection

ABSTRACT

Retrospective antibiotic surveillance data of selected invasive pathogens isolated from blood and cerebrospinal fluid at public sector hospitals in South Africa in 2007 are presented. Antimicrobial susceptibilities were determined according to the 2007 Clinical and Laboratory Standards Institute criteria. Klebsiella pneumoniae remains a highly resistant pathogen; with approximately half of all strains producing extended-spectrum beta-lactamases. All laboratories reported considerable resistance among Acinetobacter spp. Approximately 50-60of Staphylococcus aureus isolates from blood were resistant to cloxacillin. Among Streptococcus pneumoniae isolates from blood and cerebrospinal intermediate resistance to penicillin. Resistance to ceftriaxone in S. pneumoniae was rare

ABSTRACT

Objetivo: evaluar eficacia, toxicidad, preservación esfinteriana y sobrevida de un esquema ambulatorio y preoperatorio de RT-QT concurrente con 5FU, leucovorina (LV) y CDDP. Material y métodos: entre 1/93 y 12/95 ingresaron 37 pacientes (pts) con adenocarcinoma de recto (CaR) hasta 12 cm del margen anal (MA). Tratamiento: QT con 5FU 250 mg/m²/día y LV 20 mg/m²/día por 3 días más CDDP 70 mg/m²/día 1, semanas 1-3-5. RT: 180 cGy día en 28 fracciones, dosis total de 5040 cGy. Cirugía (CX): 4 a 6 semanas post RT-QT. 26 pts eran hombres; edad media 59 años (r 37-71); 22 pts (60 por ciento) tenían CaR hasta 6 cm del MA; PS 0: 13 pts, 1: 22 pts, 2: 2 pts. Resultados: el "downstaging" entre estadíos clínicos pretratamiento (PREOP) y patológicos postoperatorios (POSTOP) fue: PREOP EII 16 pts (43 por ciento), EIII 21 pts (56,8 por ciento); POSTOP Respuesta Completa patológica (RCp) 4 pts (10,8 por ciento), EI 12 pts (32,4 por ciento), EII 9 pts (24,3 por ciento), EIII 11 pts (29,7 por ciento), 1 pts fue irresecable ( resecabilidad 97,3 por ciento). Se realizó resección anterior en 23 (62 por ciento) pts (8 con CaR hasta 6 cm del MA) y operación de Miles en 14 pts. Hubo 6 recaídas locales. Toxicidad: 10 pts presentaron complicaciones postoperatorios (POSTOP). Las más frecuentes: dehiscencia anastomótica e infección ( p pts murió por sepsis postoperatorios POSTOP). La toxicidad G3 por RT-QT fue: cutánea 8 pts, diarrea 6 pts, leucopenia 3 pts; G4: vómitos 2 pts. Con una mediana de seguimiento de 32,8 meses ( rango 1-51,4 meses), la sobrevida libre de enfermedad es de 55 por ciento y la sobrevida global es de 62 por ciento. Conclusiones: éste esquema ambulatorio de Rt-QT PREOP demostró: 1) factibilidad en el ámbito hospitalario, 2) toxicidad aceptable, 3) alta tasa de resecabilidad, 4) eficacia en el downstaging, 5) una tasa de Rcp relativamente baja (10-30 por ciento en la literatura), 6) aceptable tasa de preservación esfinteriana ( 62 por ciento en la población total y 36 por ciento en los pts con CaR hasta 6 cm del MA), 7) sobrevida comparable a la reportada por el MSKCC, en experiencias sin CDDP
