Nonpuerperal breast infection

Objective: We undertook a microbiological study of purulent specimens from women with symptomatic breast abscesses.Methods: Fifty-one purulent samples were collected in 2 periods (December 1991-April 1992 and January 1994-June 1994) from nonpuerperal breast abscesses in 44 patients attending our hospital.Results: One of the most frequently isolated microorganisms was Proteus mirabilis (9 patients, 20.4%), present as a pure culture in all but 1 specimen (isolated together with Peptostreptococcus spp.). Staphylococcus aureus was isolated in 10 specimens, 6 of which were post-tumorectomy abscesses. Polymicrobial anaerobic flora were isolated in 11 specimens (21.5%); Staphylococcus epidermidis in 4 (8%); and Streptococcus milleri,Alcaligenes sp., and mixed aerobic-anaerobic flora in 1 specimen each. The 7 remaining samples (13.7%) were negative bacteriological cultures.Conclusions: We draw attention to the frequent isolation of P. mirabilis in recurrent and torpid breast abscesses in 4 women in whom surgery was necessary in addition to antibiotic treatment.     

Gigantic diverticulum of the colon. A complication of diverticulosis?]

We present a patient affected of diverticular disease of the colon, with diverticulosis and two giant diverticula of the sigma, both located at the mesenteric edge. We would like to stress the low incidence of reports about this entity in the medical literature, its uncommon location and the fact of a double lesion coinciding in a single patient. We discuss the most important nosocomial aspects and the different diagnoses. Finally, we support the idea of distinguishing three different entities that in the medical literature are usually unified as a single "giant diverticulum of the colon". We reaffirm ourselves on the importance of an early diagnosis and a correct indication for surgery.     

Knowledge and attitudes about otitis media risk: implications for prevention

OBJECTIVES: To investigate maternal knowledge and attitudes about otitis media (OM) risk, to estimate the prevalence of risk factors in the first year of life, and to identify barriers to the reduction of risk factors (eg, formula feeding, day care attendance, and exposure to passive smoke). METHODS: Questionnaires mailed to a systematic sample of 504 Minnesota women >/=18 years old identified through 1994 birth certificates. RESULTS: Eighty percent returned a completed survey. According to maternal report, 29% of infants (age 8 to 13 months) had recurrent OM (>/=3 episodes) and 2% had tympanostomy tubes. Forty-six percent attended day care, 29% had >/=1 smoking parent, and 49% breastfed for 相似文献   

前后路短节段固定融合治疗腰椎纵向劈裂骨折

目的：评价前后路短节段固定融合治疗腰椎纵向劈裂骨折的临床效果和安全性。方法：回顾性分析中南 大学湘雅二医院脊柱外科2005年3月至2013年5月采用的前后路短节段固定融合治疗的13例腰椎纵向劈裂骨折患者临床 资料,对所有患者的矫正情况进行随访,采用疼痛视觉模拟量表(visual analogue scale,VAS)评分、Oswestry功能障碍指 数(Oswestry disability index,ODI)对腰椎功能进行评估。结果：随访时间为24~60个月,平均42个月;手术时间185~300 min,平均248 min;术中失血量为600~1 500 mL,平均950 mL。所有患者术后均获得功能及自我形象的改善,在Cobb 角评估方面,术后2 d,12个月和末次随访测量Cobb角较手术前均有明显改善,差异均有统计学意义(P<0.05);VAS评 分和ODI评估术后2 d,12个月和末次随访测量结果较之术前均有改善, 差异均有统计学意义(P<0.05)。术后12个月与 末次随访的评估结果相比,差异无统计学意义(P>0.05)。根据美国脊髓损伤协会(ASIA)分级标准,在末次随访时,术 前8例D级患者中6例恢复至E级,其中3例未见进一步恢复;术前2例C级中1例恢复至D级,1例恢复至E级。所有病例 骨折均获愈合,愈合时间为3~6个月,平均4.5个月;术中3例有硬膜撕裂,术中给予修补;无神经血管损伤并发症病 例。结论：短节段伤椎置钉和旋棒复位是腰椎纵向劈裂不稳定骨折较好的手术选择。
