Efficacy and toxicity of concomitant cisplatin with external beam pelvic radiotherapy and two high-dose-rate brachytherapy insertions for the treatment of locally advanced cervical cancer

OBJECTIVE: There is no standard high-dose-rate (HDR) brachytherapy dose for locally advanced cervical cancer. The objective of this study was to determine the efficacy, toxicity and clinicopathologic predictive markers affecting survival using cisplatin (CDDP) concomitant with external beam pelvic radiotherapy (EBRT) and two 9-Gy HDR insertions for the treatment of locally advanced cervical cancer. METHODS: 77 consecutive patients with Stage IB2-IV cervical cancer treated with CDDP, EBRT and two 9-Gy HDR insertions were included. Kaplan-Meier methods and Cox proportional hazards models were applied for survival statistics. RESULTS: Median age was 53. 90% had squamous cell carcinoma. Median follow-up time was 3.5 years (range 0.5-12 years). Overall 5-year progression-free survival (PFS) was 75%. Local control rate and 5-year PFS were 88% and 83%, respectively, for Stages IB2/II, and 68% and 61%, respectively, for Stages III/IV. Grade 3/4 GI symptoms were the most common acute side effects (47%). Grade 3/4 late toxicities occurred in five (6%) patients. CONCLUSIONS: HDR brachytherapy regimens consisting of two 9-Gy HDR insertions have similar efficacy and side effect profiles as other brachytherapy regimens for the treatment of cervical cancer with improved safety and patient convenience.     

Singapore Paediatric Resuscitation Guidelines 2021

We present the 2021 Singapore Paediatric Resuscitation Guidelines. The International Liaison Committee on Resuscitation’s Pediatric Taskforce Consensus Statements on Science and Treatment Recommendations, which was published in October 2020, and the updated resuscitation guidelines from the American Heart Association and European Resuscitation Council, were reviewed and discussed by the committee. These recommendations were derived after deliberation of peer-reviewed evidence updates on paediatric resuscitation and took into consideration the local setting and clinical practice.

外科手术中产生的烟气:仅仅是大量的热空气吗?

外科医生和手术室人员经常接触手术设备产生的烟气,病人也会暴露于烟气中,特别是腹腔镜手术中产生的烟气滞留于腹腔内这一密闭空间并被吸收.这些烟气是一种与香烟烟气相似的毒性物质,然而对这种毒性物质的影响还未引起足够重视.应该采取必要措施尽可能减少手术中烟气的不良影响.     

Intrauterine growth retardation: evaluation by magnetic resonance. Work in progress

Eleven high risk fetuses between 32 and 37 menstrual weeks gestational age were examined by magnetic resonance (MR) imaging. Serial obstetrical sonograms, birth weights, and serial postnatal examinations were obtained in all subjects. Sagittal MR spin echo images obtained using TR = 0.5 sec and TE = 28 msec were useful for assessing subcutaneous fat. Prospective estimates of fetal fat stores correlated with neonatal outcome better than sonographic measurements of fetal growth parameters or actual birth weight. MR appears to be a safe and useful technique that offers information complementary to obstetrical sonography when IUGR is suspected.
