Backround

Over the last decade, an ambulatory burn care (ABC) and procedural sedation (PS) program was instituted at St Louis Children’s Hospital (SLCH). This study assessed the effect of these interventions on resource utilization.

Methods

The authors reviewed the hospital experience comparing 1993 with 2002 data regarding gender, age, burn depth, patient admissions, inpatient days, and ABC visits. Outcome measures included length of stay (LOS), incidence of infection, and hospital charges.

Results

Gender, age, and burn depth were similar; 192 patients were admitted in 1993. In 2002, there were 167 admissions and 118 patients treated solely on an ABC basis resulting in a total of 285 burn patients treated (+48%). Hospital days decreased from 2,041 (1993) to 963 (2002 [−53%]). LOS declined from 10.4 ± 8.3 days (1993) to 5.8 ± 14.2 days (2002 [−44%; P < .05]). PS was used sporadically in 1993, and increased to 71% in patients in 2002. There were no ABC visits in 1993 and 501 visits in 2002. The incidence of infection was 5.2% in 1993 versus 3.0% in 2002 (P < .05) Average charge per patient fell 45% from $13,286 (1993) to $7,372 (2002), adjusted to 1993 dollars using medical care price index.

Conclusions

Over a 10-year period, the program achieved a significant reduction in resource utilization while increasing the number of patients treated and maintaining a low incidence of infection. This was due in large part to a shift to ABC and the use of PS.  相似文献

Inhibitor of apoptosis (IAP) proteins are overexpressed in many cancers and have been implicated in tumor growth, pathogenesis, and resistance to chemo- or radiotherapy. On the basis of the NMR structure of a SMAC peptide complexed with the BIR3 domain of X-linked IAP (XIAP), a novel series of XIAP antagonists was discovered. The most potent compounds in this series bind to the baculovirus IAP repeat 3 (BIR3) domain of XIAP with single-digit nanomolar affinity and promote cell death in several human cancer cell lines. In a MDA-MB-231 breast cancer mouse xenograft model, these XIAP antagonists inhibited the growth of tumors. Close structural analogues that showed only weak binding to the XIAP-BIR3 domain were inactive in the cellular assays and showed only marginal in vivo activity. Our results are consistent with a mechanism in which ligands for the BIR3 domain of XIAP induce apoptosis by freeing up caspases. The present study validates the BIR3 domain of XIAP as a target and supports the use of small molecule XIAP antagonists as a potential therapy for cancers that overexpress XIAP.  相似文献

We present a case illustrating the use of eye movement desensitization and reprocessing (EMDR) in the treatment of psychogenic seizures. These seizures were events lasting many hours, necessitating frequent emergency room visits and an extensive medical work up. Given the patient's history, posttraumatic stress disorder (PTSD) was diagnosed. EMDR is widely used as a treatment modality for PTSD, and the patient was referred for once-per-week treatment, with complete recovery after 18 months of therapy. The impact of her recovery on her quality of life was astonishing. This case supports the notion that EMDR can be an effective alternative treatment for psychogenic seizures, especially when the history reveals a traumatic event or abusive experiences.  相似文献

BACKGROUND: Obturator nerve injury is a rare complication of vaginal delivery. CASE: Postpartum obturator neurapraxia was clinically diagnosed in a 22-year-old woman on the first postpartum day after a vaginal delivery. With physical therapy, the neurologic symptoms resolved by the third postpartum month. CONCLUSION: Maternal nerve injuries are uncommon in obstetrics. The diagnosis of obturator neurapraxia is usually made clinically. The symptoms will resolve with conservative physical therapy alone in the majority of cases.  相似文献
