Breastfeeding in Prevention of Postpartum Acute Pancreatitis.

BACKGROUND: Acute pancreatitis (AP) caused by gallstones has an increased rate of incidence in young women in the 2 years postpartum. Middle-aged women with longer periods of breastfeeding have less hospitalization for gallbladder disease. AIM: To investigate whether breastfeeding or other variables may be associated with AP. METHODS: We conducted a population-based case-control study among all Sicilian women of childbearing age, and we identified all women who delivered (2013-2016) and had AP within 2 years postpartum. We reviewed their medical records, and for each case we matched four women of the same age (± 5 years), without AP. Univariate and multivariate logistic regression was used to estimate the odds ratios (OR) with their confidence intervals (CI) to assess associations between AP and clinical determinants. RESULTS: In the 74 women with AP and 298 controls at univariate analysis, > 6 months oral contraception history (p < 0.01; OR 3.30; 95% CI 1.33-8.16), previous biliary disease (p < 0.001; OR 5.90; 95% CI 1.98-17.57) and smoking (p = 0.035; OR 2.04; 95% CI 1.04-4.0) were predictors of AP; amenorrhea ≥ 3 months (p < 0.001; OR 0.34; 95% CI 0.19-0.59) and breastfeeding ≥ 3 months (p < 0.001; OR 0.07; 95% CI 0.03-0.14) were protective. At multivariate analysis, previous biliary disease (p = 0.011; OR 5.49; 95% CI 1.48-20.38) and breastfeeding ≥ 3 months (p < 0.001; OR 0.06; CI 95% 0.03-0.14) were associated with AP. CONCLUSIONS: Women who breastfeed for at least 3 months and do not have a history of biliary disorders have reduced risk of developing AP in the 2 years after delivery.

Polymyalgia rheumatica and vertebral fractures: a 1-year pilot controlled study.

No data exist about the possibility that vertebral fracture in PMR patients could be independent of steroid therapy. For this reason, we aimed to investigate this topic by a case cohort study with a 1-year follow-up for each patient. We selected ten consecutive patients who experienced vertebral fractures (VF-group) during the first month of 1-year follow-up period and without any other significant associated condition. As a control group we studied ten control patients, without vertebral fractures and with a follow-up of 1 year, randomly selected among a larger group of patients affected by polymyalgia rheumatica. The following data were analysed: eritrosedimention rate (ESR), visual analogical scale score (VAS), methyprednisolone daily dosage. Each patient had been monthly evaluated by the aforementioned clinical and laboratoristic parameters during the 1-year follow-up period. The VF-group resulted with a higher and statistically significant median corticosteroid 12-month total dosage [mean 3,480 mg (95%CI 2,805-3,030) vs. 2,760 mg (2,666.25-3,247.5)]. The VF-group had statistically significant higher ESR and VAS AUC when compared to control group (median ESR AUC, 484.75 vs. 288.25; P = 0.0001; median VAS AUC, 70.75 vs. 43.5 P < 0.0001); ESR at the baseline (cut-off >80 mm) showed a specificity of 90% (95%CI 56-100) and sensitivity of 70% (95%CI 35-93). VAS difference from first to second month (cut-off

Evidence-Based Knowledge Management: an approach to effectively promote good health-care decision-making in the Information Era.

The sharing of information and the growth of knowledge together represent a foundation for the promotion of quality improvement of health care systems. This paper concerns knowledge, not only from an epistemological point of view, but also from a pragmatic one. In our paper, knowledge is discussed as the hub to promote better decision making and continuous professional development. Effective thinking is particularly needed. The critical point is to think about how health care systems can develop both an effective knowledge management network and how health-care organizations can actually be based on it. In this way, knowledge and knowledge hierarchy are defined according to Russel Achkoff's vision. Generally, knowledge is crucial in decision-making, and Evidence-Based Medicine has its roots in knowledge. In particular, information management is the basis for a significant production of knowledge to promote good health-care decision-making. Thus, relationships between knowledge management and Evidence-Based Medicine are discussed, and a new paradigm is proposed: the Evidence-Based Knowledge Management. Finally, the role of Evidence-Based Knowledge Management within Clinical Governance is discussed together with some considerations about clinical governance implementation problems in Italy.

Safety of etanercept therapy in rheumatoid patients undergoing surgery: preliminary report.

This is a preliminary report on a case-series of rheumatoid patients that underwent various kinds of elective surgery but did not withdraw etanercept therapy in spite of physician advise. Elective surgery consisted of right knee surgical prosthesis, bilateral cataract, bilateral hallux valgus, right hip prosthesis, bladder stone by cystoscopy and left inguinal hernia. All the patients had a regular healing rate. During follow-up (6-12 months) no one of these patients were suffering from infective complications after surgery. According to same recent literature results, our data suggest that it is the time to value rheumatoid patient preferences through a correct information about cost-benefit of this treatment to establish together with patients if etanercept therapy has to be discontinued before and after elective surgery. Finally, we think that adverse drug reaction surveillance has to be boosted, and editors of leading scientific journal should publish more papers on case-series about drug safety and tolerability in particular conditions.

Improving efficacy of PubMed Clinical Queries for retrieving scientifically strong studies on treatment.

The authors evaluated the retrieval power of PubMed "Clinical Queries," narrow search string, about therapy in comparison with a modified search string to avoid possible retrieval bias. PubMed search strategy was compared to a slightly modified string that included the Britannic English term "randomised." The authors tested the two strings joined onto each of four terms concerning topics of broad interest: hypertension, hepatitis, diabetes, and heart failure. In particular, precision was computed for not-indexed citations. The added word "randomised" improved total citation retrieval in any case. Total retrieval gain for not-indexed citations ranged from 11.1% to 21.4%. A significant number of Randomized Controlled Trial(s) (RCT)s (9.1-18.2%) was retrieved for each of the selected topics. They were often recently published RCTs. The authors think that correction of the Clinical Queries filter (when they focus on therapy and use narrow searches) is necessary to avoid biased search results with loss of relevant and up-to-date scientifically sound information.

A systematic approach to medical decision-making of uncommon clinical pictures: a case of ulcerative skin lesions by palm tree thorn injury and a one-year follow-up.

In clinical practice, the clinician is challenged with symptoms and/or signs at times apparently insoluble by diagnostic and/or therapeutic means. We propose that in these cases, we have to use an EBM approach in which evidence may be looked up in every available clinical report and bibliographic databases are used for searching that evidence. We report on a case of ulcerative skin lesions apparently insoluble by expert dermatologists following a conventional diagnostic and therapeutic process. We use this case report for illustrating a systematic approach to resolve diagnostic and therapeutic questions using a bibliographic database search (like MEDLINE and EMBASE). Both a systematic approach to bibliographic databases and a critically appraised topic on case reports (or case series) are needed to 'rehabilitate' low-level evidences (that is a case report or case series) to a higher level when we approach decision-making of uncommon clinical pictures. We demonstrate the possibility of using bibliographic databases to search and retrieve useful information for decision-making of uncommon clinical pictures. The method we have proposed can be applied in every area of the world, especially in rural areas. Finally, an Internet-shared database of uncommon clinical pictures with critically appraised topics could be useful in saving more time.

[The health technology assessment]. / La valutazione delle tecnologie sanitarie.

The aim of this paper was to describe exhaustively, but concisely, the matter of the health technology assessment. It is a method of evaluating health technologies based on principles and tools of Evidence Based Medicine. We started from etymology to speak about its definition and implementation methodology. Moreover we guide the reader throughout the constellation of international societies of health technology assessment and the meaning of their international cooperation. Finally, we deal with the health technology assessment as a tool being an integral part of the clinical governance process.

[Biomedical information on the internet using search engines. A one-year trial]. / Informazione biomedica su internet e motori di ricerca. Risultati di un trial di un anno.

The internet is a communication medium and content distributor that provide information in the general sense but it could be of great utility regarding as the search and retrieval of biomedical information. Search engines represent a great deal to rapidly find information on the net. However, we do not know whether general search engines and meta-search ones are reliable in order to find useful and validated biomedical information. The aim of our study was to verify the reproducibility of a search by key-words (pediatric or evidence) using 9 international search engines and 1 meta-search engine at the baseline and after a one year period. We analysed the first 20 citations as output of each searching. We evaluated the formal quality of Web-sites and their domain extensions. Moreover, we compared the output of each search at the start of this study and after a one year period and we considered as a criterion of reliability the number of Web-sites cited again. We found some interesting results that are reported throughout the text. Our findings point out an extreme dynamicity of the information on the Web and, for this reason, we advice a great caution when someone want to use search and meta-search engines as a tool for searching and retrieve reliable biomedical information. On the other hand, some search and meta-search engines could be very useful as a first step searching for defining better a search and, moreover, for finding institutional Web-sites too. This paper allows to know a more conscious approach to the internet biomedical information universe.
