Hypersensitivity reactions （HSR） to oxaliplatin in patients with colorectal cancer include facial flushing, erythema, pruritis, fever, tachycardia, dyspnea, tongue swelling, rash/hives, headache, chills, weakness, vomiting, burning sensations, dizziness, and edema. We report a patient with fever as the sole manifestation of initial HSR, review the literature and discuss the management of HSR. A 57-year-old female with T3N2M0 rectal adenocarcinoma received modified FOLFOX-6. She tolerated the first 8 cycles without any toxicities except grade 1 peripheral neuropathy and nausea. During 9th and 10th infusions, she developed fever to a maximum of 38.3℃ with stable hemodynamic status despite medications. During 11th infusion, she developed grade 3 HSR consisting of symptomatic bronchospasm, hypotension, nausea, vomiting, cough, and fever. On examination, she was pale, cyanotic, with a temperature of 38.8℃, BP dropped to 95/43 mm Hg, pulse of 116/min and O2 saturation of 88%-91%. She was hospitalized for management and recovered in 24 h. Fever alone is not a usual symptom of oxaliplatin HSR. It may be indicative that the patient may develop serious reactions subsequently, as did our patient who developed hypotension with the third challenge. Treatment and prevention consists of slowing the infusion rate, use of steroids and antagonists of Type 1 and 2 histamine receptor antagonists, whereas desensitization could help to provide the small number of patients who experience severe HSR with the ability to further receive an effective therapy for their colorectal cancer.

Carbon powders have the ability to remove cholesterol from solution by adsorption. Various combinations from among 12 different types of carbon powders （including two medical carbons）, having a wide range of surface area and porosity, were used to perform cholesterol adsorption experiments. The cholesterol concentration in a cyclohexane solvent （37 ~C, shaking 200 rpm） was detected at 215 nm using ultraviolet spectroscopy. Most adsorption occurred in the first 30 to 60 minutes. A Langmuir model was used to fit the amount of cholesterol adsorbed per gram of carbon. The medical carbon, Natural Elements Activated Charcoal, adsorbed 234 mg of cholesterol adsorption per gram of carbon. The experimental percentages of cholesterol removed from solution （maximum 98%） were correlated with nitrogen Branauer-Emmett-Teller （BET） surface areas and micro, meso, and macropore volume distributions. Surface area alone was not a suitable predictor of cholesterol adsorption. However, carbon powders exhibiting a large surface area along with significant meso and macropores were shown to be effective in adsorbing cholesterol from a nonpolar environment. Ingestion of a medically approved carbon powder with a large surface area and sufficient meso and macroporosity may be able to adsorb cholesterol in the intestinal tract and thereby lower cholesterol levels in the body.

人们都能本能地认识到自尊在心理健康方面的重要性,因此,只要可能,我们大都会竭力保护和增强我们的自尊,这并无什么特别之处.其所以不同一般,是因为人们对自尊的关注,已经使它成为一个全社会的热门话题,至少在美国是如此;因为,在美国人看来,对自己有一个较美好的认识,乃是核心的心理源泉,一切积极、正面的结果均源于此.自尊太差的根源在于个人,由此引发出种种社会问题以及社会机能障碍,这一认识使得自尊成为数十年来社会一直都努力要加以解决的问题之一.的确,试图提高人们自我价值感的种种努力,可以说是层出不穷.

The role of arthroscopic partial meniscectomy(APM) in reducing pain and improving function in patients with meniscal tears remains controversial. Five recent highquality randomized controlled trials(RCTs) compared non-operative management of meniscal tears to APM, with four showing no difference and one demonstrating superiority of APM. In this review, we examined the strengths and weaknesses of each of these RCTs, with particular attention to the occurrence of inadvertent biases. We also completed a quantitative analysis that compares treatment successes in each treatment arm, considering crossovers as treatment failures. Our analysis revealed that each study was an excellent attempt to compare APM with non-surgical treatment but suffered from selection, performance, detection, and/or transfer biases that reduce confidence in its conclusions. While the RCT remains the methodological gold standard for establishing treatment efficacy, the use of an RCT design does not in itself ensure internal or external validity. Furthermore, under our alternative analysis of treatment successes, two studies had significantly more treatment successes in the APM arm than the non-operative arm although original intention-totreat analyses showed no difference between these two groups. Crossovers remain an important problem in surgical trials with no perfect analytical solution. With the studies available at present, no conclusion can be drawn concerning the optimal treatment modality for meniscal tears. Further work that minimizes significant biases and crossovers and incorporates sub-group and cost-benefit analyses may clarify therapeutic indications.

Open Journal of Anesthesiology 2013年第1期3卷 51-56页

Treatment of ischemic stroke for a patient on left ventricular assist device (LVAD) by neurointerventional means is rare and many anesthesia providers are unfamiliar with both LVAD and neurointerventional protocols. Examples of this include: 1) filling for continuous-flow LVAD depend on preload and the flow is inversely related to afterload;as mean arterial pressure (MAP) increases above 80 to90 mmHg, flow decreases;2) there may be no palpable pulse in patients with continuous flow LVADs;3) pulse oximetry may not work when pump flow is high and native myocardial function is minimal;4) increasing MAP above80 mmHg potentially will maintain ischemic brain tissue—the penumbra—until flow is restored. This latter example creates a paradoxical management goal: increasing the mean arterial pressure (MAP) above80 mmHg while maintaining ischemic brain tissue, may decrease flow to the LVAD. Finally, there is controversy regarding which type of anesthesia is most efficacious for neuro interventional procedures. We describe three patients on LVAD suffering ischemic stroke requiring anesthesia for embolectomy and angioplasty during neruointeventioal radiology procedures.

INTRODUCTION Efforts to contain and respond to the novel COVID-19 in both high-income and low-income countries remain extremely ***-constrained countries face the additional obstacles of limited health infrastructure and inability to socially distance due to crowded and often multigenerational living *** Western nations begin mass vaccination campaigns,many countries in the Global South may not receive the vaccine for months or years.
