Abstract Objective.—Diagnostic hematopathology depends on the applications of flow cytometric immunophenotyping and immunohistochemical immunophenotyping combined with the cytomorphology and histologic features of each case. Select cases may require additional ancillary cytogenetic and molecular studies for diagnosis. The purpose of this review is to focus on the applications of flow cytometric and immunohistochemical immunophenotyping of paraffin-embedded tissue to diagnostic hematopathology. Advantages and disadvantages of these techniques are examined. Data Sources.—The literature is extensively reviewed (PubMed 1985–2003) with an emphasis on the most recent applications and those that are most useful clinically, both diagnostically and prognostically. Study Selection.—Studies were selected based on statistically significant results in large studies with reported adequate clinical follow-up. Data Extraction.—The methodology was reviewed in the selected studies to ensure reliable comparison of reported data. Data Synthesis.—Flow cytometric immunophenotyping offers the sensitive detection of antigens for which antibodies may not be available for paraffin immunohistochemical immunophenotyping. However, paraffin immunohistochemical immunophenotyping offers preservation of architecture and evaluation of expression of some proteins, which may not be available by flow cytometric immunophenotyping. These techniques should be used as complimentary tools in diagnostic hematopathology. Conclusions.—There are extensive applications of flow cytometric and immunohistochemical immunophenotyping to diagnostic hematopathology. As cytogenetic and molecular findings evolve in diagnostic hematopathology, there may be additional applications of flow cytometric and immunohistochemical immunophenotyping to this field of pathology.

PurposeThe purpose of this systematic review was to identify an appropriate method—a user-friendly and validated method—that prioritises recommendations following analyses of adverse events (AEs) based on objective features.Data sourcesThe electronic databases PubMed/MEDLINE, Embase (Ovid), Cochrane Library, PsycINFO (Ovid) and ERIC (Ovid) were searched.Study selectionStudies were considered eligible when reporting on methods to prioritise recommendations.Data extractionTwo teams of reviewers performed the data extraction which was defined prior to this phase.Results of data synthesisEleven methods were identified that are designed to prioritise recommendations. After completing the data extraction, none of the methods met all the predefined criteria. Nine methods were considered user-friendly. One study validated the developed method. Five methods prioritised recommendations based on objective features, not affected by personal opinion or knowledge and expected to be reproducible by different users.ConclusionThere are several methods available to prioritise recommendations following analyses of AEs. All these methods can be used to discuss and select recommendations for implementation. None of the methods is a user-friendly and validated method that prioritises recommendations based on objective features. Although there are possibilities to further improve their features, the ‘Typology of safety functions’ by de Dianous and Fiévez, and the ‘Hierarchy of hazard controls’ by McCaughan have the most potential to select high-quality recommendations as they have only a few clearly defined categories in a well-arranged ordinal sequence.

OBJECTIVE: To review the current published clinical studies evaluating the clinical efficacy and safety of lactulose compared with other laxatives or placebo. Adverse effects associated with lactulose are also reported. DATA SOURCES: Information was retrieved by searching the MEDLINE and EMBASE databases for clinical trials, abstracts, conference proceedings, and review articles dealing with lactulose. STUDY SELECTION: Emphasis was placed on clinical trials where lactulose was compared with other laxatives or placebo in patient populations where the diagnosis of constipation was reasonably established. DATA EXTRACTION: The methodology and results from clinical studies were evaluated. Assessment of the studies was made based on diagnosis of constipation, prior management of patients, follow-up of patients, dosage, and adverse effects. DATA SYNTHESIS: Clinical trials in geriatric patients, terminally ill patients, children, and normal and constipated subjects were reviewed. In most instances, lactulose was compared with a placebo, without incorporating the current education on dietary techniques for improving defecation. CONCLUSIONS: Generally, clinical trials have demonstrated a beneficial response compared with placebo, although sometimes that response has been only marginally better, from a clinical point of view.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.

Abstract Objective.—To investigate the nature of creative thinking in biomedical science with specific applications to molecular pathologies and DNA technologies. Data Sources.—Accounts of breakthroughs and inventions contained in autobiographies, biographies, interviews, and archival sources. Study Selection.—Discoveries that have altered, or may yet alter, basic textbook accounts of biomedical sciences for which appropriate data sources exist. Data Extraction.—Approximately 1000 data sources were analyzed, both within appropriate sciences and in other creative fields, such as the arts. Data Synthesis.—The current analysis is based on a framework described in our previous book, Sparks of Genius, which outlines a general approach to understanding creative thinking. Conclusions.—Creative thinking in all disciplines depends on a common mental “toolkit” that consists of 13 fundamental tools: observing, imaging, abstracting, pattern recognition, pattern forming, analogizing, body thinking, empathizing, dimensional thinking, modeling, playing, transforming, and synthesizing. Scientists recognize and solve problems by observing data that break the patterns established by theories; exploring a system by creating an abstract model with which they can play; and transforming data into feelings, sounds, and other forms that create surprising analogies to already-understood principles. The result of such personal thinking is knowledge combined with sensation and emotion—feeling and understanding synthesized into complete awareness. We illustrate some of these modes of thinking with reference to recent breakthroughs in DNA-related areas and suggest ways in which the use of “tools for thinking” can increase the probability of making further discoveries in the biomedical sciences.

OBJECTIVE To review the history of drug regulation by the Food and Drug Administration (FDA) as it relates to unapproved drugs and FDA policy, along with the FDA's efforts to avoid future incidents by amending and enforcing those policies that are already in place. DATA SOURCES Data from FDA history documents, FDA guidances, Code of Federal Regulations Title 21, and presentations by the FDA's Office of Compliance were gathered. STUDY SELECTION AND DATA EXTRACTION All information identified from the data sources was evaluated, and all information deemed relevant was included for this review. DATA SYNTHESIS Contrary to popular belief, there are drugs on the market that have not been evaluated for safety or efficacy by the FDA. For almost a century, the FDA has taken action against public health threats posed by unapproved drug products, and today's drugs and vaccines are required to demonstrate both safety and efficacy prior to marketing. The FDA has taken great strides to ensure the welfare of Americans by reacting to disasters that have occurred in the past and being proactive by setting regulations that will prevent such catastrophes from occurring in the future. CONCLUSIONS The FDA recognizes that drug regulation is an ongoing process and that, although we have come a long way, there is still much to be done.

The Impact

Background. The impact of providing information about medicines to patients on decisions about starting or continuing them is unknown. Purpose. To estimate the impact on decisions to start or continue medicines, of providing information to patients about possible benefits and/or harms. Data Sources. Electronic searches from 1980 to October 2010; reference and citation searches of included studies. Study Selection. Two investigators assessed studies' eligibility against inclusion criteria: randomized or pseudorandomized trials; participants older than 16 years and deciding for themselves; one group received information about possible benefits and/or harms of a potentially beneficial medicine, compared with another who did not; d) a measure of decision about starting or continuing a medicine. Data Extraction. One investigator extracted all data, checked by a second. Data Synthesis. Eight studies were included, covering a range of medicines. There was no consistent impact of interventions on decisions about whether to start or continue medicines (pooled odds ratio 1.08; 95% confidence interval [CI], 0.69–1.70; P = 0.74). Among those who received more information, knowledge was increased (pooled mean difference 8.47; 95% CI 2.17–14.77; P = 0.008), and decisional conflict was reduced (pooled mean difference -0.15; 95% CI -0.24 to -0.06; P = .001). Limitations. A small number of studies across different clinical contexts, of uncertain heterogeneity, were included. Conclusions. Providing information to patients about possible benefits and/or harms has no consistent effect on the number who decide to start or continue medicines, although it increases patients' knowledge and reduces their decisional conflict.

Objective To evaluate the evidence regarding the association between lateral ankle sprain (LAS) history and the subsequent LAS risk, as well as sex differences in the observed associations. Data Sources PubMed, CINAHL, and SPORTDiscus were searched through July 2020 for articles on LAS history and incidence during the study period. Study Selection Studies were included if they were prospective in nature and the authors reported the number of participants with and those without a history of LAS at study initiation as well as the number of participants in each group who sustained an LAS during the investigation. Data Extraction Data were study design parameters as well as the number of participants with and those without an LAS history and the number of subsequent LASs that occurred in both groups. Risk ratios (RRs) with 95% CIs compared the risk of LAS during the study period between those with and those without an LAS history for each investigation. Data Synthesis A total of 19 studies involving 6567 patients were included. The follow-up periods ranged from 14 weeks to 2 years. Assessment scores indicated the studies were of moderate to high quality. A significantly higher risk of LAS during the study period was observed among those with a history of LAS in 10 of 15 studies (RR range = 1.29–6.06). Similar associations were seen in 4 of 6 studies of all-male samples (RR range = 1.38–8.65) and 1 of 4 studies with an all-female sample (RR = 4.28). Conclusions Strong evidence indicates that a previous LAS increased the risk of a subsequent LAS injury. Men with a history of LAS appeared to be at a higher risk of sustaining a subsequent LAS, but women were not. However, further data are needed to draw definitive conclusions from the limited number of sex-specific studies.

OBJECTIVE: To review and evaluate the literature relative to the use of herbal therapies in the treatment of benign prostatic hyperplasia. DATA SOURCES: Literature was identified by MEDLINE, Embase, International Pharmaceutical Abstracts, and the International Bibliographic Information on Dietary Supplements searches and through cross-referencing of selected articles. STUDY SELECTION/DATA EXTRACTION: All articles identified from the data sources were evaluated and all information deemed relevant was included in this review. DATA SYNTHESIS: A large percentage of men >50 years old begin to experience signs and symptoms of benign prostatic hyperplasia (BPH). Herbs hold promise in the treatment of BPH. Serenoa repens, Pygeum africanum, Urtica dioica radix, and Cucurbita peponis semen are some of the botanical therapies used in the treatment of BPH. CONCLUSIONS: There are many European studies examining efficacy, dose, and adverse effects of these plants in the treatment of BPH. However, numerous questions remain. These include issues concerning long-term beneficial and adverse effects of herbal therapy, prevention of complications, standardization of extracts, and concomitant use with “mainstream” medications. Based on the information available today, these botanical therapies can be used for treatment of a number of objective and subjective symptoms in patients with BPH, stages I and II.

Objective: To review the incidence, risk factors, and management of pegfilgrastim-induced bone pain (PIBP). Data Sources: PubMed was searched from 1980 to March 31, 2017, using the terms pegfilgrastim and bone pain. Study Selection and Data Extraction: English-language, human studies and reviews assessing the incidence, risk factors, and management of PIBP were incorporated. Data Synthesis: A total of 3 randomized, prospective studies and 2 retrospective studies evaluated pharmacological management of PIBP. Naproxen compared with placebo demonstrated a reduction in the degree, incidence, and duration of bone pain secondary to pegfilgrastim. Loratadine was not effective in reducing the incidence of bone pain prophylactically, but a retrospective study evaluating dual antihistamine blockade with loratadine and famotidine demonstrated a decreased incidence in bone pain when administered before pegfilgrastim. Conclusion: Naproxen is effective at managing PIBP. Although commonly used, antihistamines have a paucity of data supporting their use. Dose reductions of pegfilgrastim and opioids may also be potential management options; however, data supporting these treatment modalities are scarce.
