Background: Management of postoperative pain has become a growing concern, even for minor gynecological procedures. Proper postoperative pain management has been shown to lead to earlier mobilization, shortened hospital stay, and increased patient satisfaction. The optimal means of reducing the pain of pregnancy termination has not yet been determined.

Objectives: To compare the efficiency in pain management of two drugs, lornoxicam and paracetamol, given intravenously postoperatively to women who underwent abortion with dilation and curettage. 

Methods: The cohort comprised 80 women scheduled for dilation and curettage for pregnancy termination at 6–12 gestational weeks. The anesthesiologist gave 1000 mg paracetamol or 20 mg lornoxicam soon after starting the procedure, according to a randomization table. The medical staff and the patients were blinded to the drug that was administered. Pain levels were evaluated by a 10 cm visual analogue scale (VAS) at 15, 30, 60, 90, and 120 minutes following arrival at the postoperative care unit. 

Results: Mean levels of pain decreased from 60 minutes postoperative until the end of recording, reaching minimum levels at 120 minutes: 0.8 ± 0.19 and 1.5 ± 0.28, for lornoxicam and paracetamol, respectively. The differences between the groups were statistically significant (P < 0.05 from 60 minutes after the procedure until the time of discharge. 

Conclusions: Compared to women who received paracetamol, women who received lornoxicam after dilation and curettage for termination of pregnancy reported lower levels of pain, from 30 minutes postoperative until the time of discharge following the procedure. 

Objectives: To characterize common obstetric anesthesia practices after cesarean deliveries in Israel in order to standardize postoperative pain relief protocols.

Methods: A questionnaire was completed during an interview with every obstetric anesthesia unit in all 25 delivery wards in Israel. Data were gathered on intraoperative anesthesia and analgesia protocols as well as postoperative pain relief protocols. A sub-analysis compared units whose director completed a formal obstetric anesthesia training program with those whose directors did not.

Results: Neuraxial morphine was used routinely in 12% of hospitals. No unit providing intrathecal morphine complied with American Society of Anesthesiologists guidelines for respiratory monitoring after use of neuraxial opioids. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) were used routinely in only half the wards, while patient-controlled analgesia was used infrequently. Postoperative verbal analog scores were not recorded routinely in 71% of units on postoperative day 1. The unit director's training significantly influenced the unit protocols.

Conclusions: Intrathecal morphine, the gold standard of care in cesarean deliveries, is rarely used, mainly due to shortage of staff and lack of formal obstetric anesthesia training. In addition, NSAIDs are also underused. There is a need for more formal training for obstetric anesthesiologists in Israel.

Non-steroidal anti-inflammatory drugs, mainly ibuprofen, are extensively used in children as analgesics and antipyretics.

Background: Alteration of innate and acquired immunity can play a role in the mechanism involved in the development of dementia. Epidemiologic studies indicate that the use of non-steroidal anti-inflammatory drugs can delay the onset or slow progression of Alzheimer disease.

Objectives: To determine whether the use of NSAIDs[1] is associated with natural killer activity alteration in AD[2] and multi-infarct vascular dementia patients, as compared with non-demented elderly and healthy young people.

Methods: In this prospective open study four groups of subjects (AD, VD[3], non-demented elderly, and healthy young people) were treated with an NSAID drug (rofecoxib 12.5 mg/day or ibuprofen 400 mg twice daily) for 7 days. Natural killer cell cytotoxicity was measured after flow cytometry analysis before and after treatment.

Results: Of the 49 subjects studied, 15 had a diagnosis of AD (3 men, 12 women; mean age 83.5 ± 8.1 years), 15 had a diagnosis of multi-infarct VD (7 men, 8 women; mean age 75.5 ± 8.4), 13 were non-demented elderly (1 man, 12 women; mean age 80.2 ± 7.2), and 6 were healthy young volunteers (3 men, 3 women; mean age 36.8 ± 4.4). While all examined subjects showed decreased NK[4] cell cytotoxicity after treatment, this decrease was most prominent and statistically significant in elderly patients suffering from vascular dementia –  from an average of 30.5 ± 11.8% before treatment to 22.5 ± 16% after treatment (P = 0.04). The decrease in NK cell cytotoxicity was only moderate and not statistically significant in all other elderly and young subjects. Young healthy volunteers exhibited a significantly higher total NK cytotoxicity before and after treatment compared to all age groups (P < 0.001).

Conclusion: These findings suggest that NSAIDs decrease NK activity in vascular dementia patients. Our findings also suggest that natural killer activity alteration cannot explain the ability of anti-inflammatory drugs to delay the onset or slow the progression of AD.

Background: Elevated fibrinogen levels are considered a risk factor for the development of atherosclerosis and might be used as a predictor of risk for the development of atherothrombotic events. Several studies have reached equivocal conclusions regarding the effect of statins on fibrinogen.

Objectives: To evaluate the effect of atorvastatin on plasma fibrinogen levels in patients with severe hypercholesterolemia and no other risk factors.

Methods: Twenty-two patients with low density lipoprotein-cholesterol levels above 170 mg/dl (4.40 mmol/L) and with no other risk factors were included in the study. None of the patients had ever received hypolipidemic medication. Patients were followed for 24 weeks (6 office visits 4 weeks apart). During office visits, lipid profile, complete blood count, fibrinogen and C-reactive protein levels were measured.

Results: After 24 weeks of follow-up, total cholesterol decreased by 33% (287 ± 10 to 192 ± 8 mg/dl, P < 0.001), LDL-C[1] by 45% (198 ± 8 to 111 ± 7 mg/dl, P < 0.001) and triglycerides by 21% (189 ± 26 to 138 ± 15 mg/dl, P <0.001). Fibrinogen levels dropped by 18% (355 ± 26 to 275 ± 7 mg/dl, P = 0.01). CRP[2] levels decreased from 0.51 ± 0.15 to 0.28 ± 0.10 mg/dl, but the difference was not statistically significant (P = 0.09). High density lipoprotein, hemoglobin, white blood cell and platelet counts did not change.

Conclusions: We found that atorvastatin reduces plasma fibrinogen in patients with hypercholesterolemia.

Sepsis is an inflammatory syndrome caused by infection. Consequently, anti-inflammatory therapies in sepsis have been a subject of extensive research and corticosteroids have been used for years in the therapy of severe infections. However, studies conducted in the 1980s failed to demonstrate any beneficial effects of high dose, short-term steroid therapy in sepsis and this therapy was therefore abandoned during the last decade. Recently, a new concept has emerged with more promising results - low dose, long-term hydrocortisone therapy – and this approach is now being evaluated in the treatment of septic shock. It is supported by the observation that many sepsis patients have relative adrenal insufficiency. Moreover, the anti-inflammatory effects of steroids and their ability to improve reactivity to catecholamines further contribute to their effects in sepsis. Large randomized clinical trials will be required to determine the exact role of corticosteroids in septic shock.

There is increasing evidence to suggest that aspirin and other non-steroidal anti-inflammatory drugs reduce the risk of colorectal cancer. This observation is supported by animal studies that show fewer tumors per animal and fewer animals with tumors after administration of several different NSAIDs. Intervention data in familial adenomatous polyposis have established that the effect is exerted on the process of human colonic adenoma formation. Supportive evidence in sporadic colorectal neoplasia, derived from 22 of 24 studies (both case-control and cohort), found a reduced risk in men and women for cancers of the colon and the rectum and for both aspirin and the other NSAIDs. Earlier detection of lesions as a result of drug-induced bleeding does not seem to account for these findings. Although the molecular mechanism responsible for the chemopreventive action of this class of drugs is not yet completely understood, the protection may affect several pathways including both cell cycle arrest and induction of apoptosis.

In the third millennium the question is not if but how. Based on the consistency of epidemiological, clinical and experimental data, the association between regular long-term aspirin or NSAIDs intake and a decreased death rate from colorectal cancer is sound and there is no need for further placebo trials. At the same time, despite this consistency there is no clear data on the dose, duration or frequency of use for cancer-preventive activity.
