A patient with an interstitial deletion of the short arm of chromosome 6

The clinical history and subsequent progress of a child with an interstitial deletion in the short arm of chromosome 6 is described. This abnormality coupled with a reduced Hageman factor (Factor XII) led to an earlier publication which suggested that this gene was localized to the breakpoint region involved. A review of similar phenotypes from the literature is presented.     

Pancreatic glucagonoma with and without syndrome

Summary In five patients single or multiple glucagonomas were characterized by immunocytochemistry. Two large single glucagonomas were associated with the glucagonoma syndrome, which completely dissappeared after removal of the tumours. The morphologic findings in these patients are compared with 48 others collected from literature.In the other three patients, the glucagonomas were not associated with a clinical syndrome and were detected by chance (one accompanying an insulinoma; the other in pancreases of patients suffering from multiple endocrine neoplasia I; MEN I). These tumours appeared by their histological, immunocytochemical and ultrastructural features better organized than the glucagonomas with syndrome.Glucagonomas not producing a syndrome can be classified into (a) solitary, often malignant endocrine pancreatic tumours, (b) glucagonomas associated with insulinomas and other tumours, (c) multiple glucagonomas in MEN I and (d) single microglucagonomas in elderly patients. It is emphasized that only immunohistology allows clear identification of these tumours as glucagonomas.     

Pathophysiology of mild endometriosis: review of literature

Endometriosis is a puzzling condition and the literature ischaracterized by a large number of uncontrolled reports on itsaetiology and pathophysiology. In particular the relationshipbetween mild endometriosis and subfecundity is uncertain. Thispaper critically reviews the published literature on the pathogenesis,prevalence, menstrual symptomatology and natural history ofendometriosis. Furthermore, factors implicated in causing subfecundityin relation to endometriosis and the impact of various treatmentsin enhancing fertility among women with mild endometriosis havebeen assessed.     

Intraparenchymal pulmonary lymph node: case report and literature review

Summary A case of a 44-year-old woman with a solitary pulmonary coin lesion is presented. Histologic study of this nodule revealed a normal intraparenchymal pulmonary lymph node. A review of the literature discusses the incidence and characteristics of this entity.

The History and Future of the “ISPOR Value Flower”: Addressing Limitations of Conventional Cost-Effectiveness Analysis

ObjectivesSince its publication as part of the 2018 ISPOR Special Task Force (STF) on US Value Assessments, the “ISPOR value flower,” with its petals highlighting elements that may be overlooked or underappreciated in conventional drug value assessments, has been discussed and debated. We review the history of the value flower, describe recent developments, and consider implications for future value assessments.MethodsWe discuss various antecedents to the value flower, as well as conceptual and empirical articles published in the past 4 years.ResultsSince the publication of the ISPOR STF report, researchers have provided more rigorous theoretical and mathematical foundations for certain novel value elements (eg, severity of illness, value of insurance, value of hope) through “generalized risk-adjusted cost-effectiveness analysis,” which incorporates risk aversion in people’s preferences and uncertainty in treatment outcomes. Empirical estimates are also emerging to support key elements, such as insurance value, real option value, value of hope, and value of knowing. Although health technology assessment bodies have applied or are considering certain elements (eg, severity modifiers to cost-effectiveness thresholds), other elements have yet to gain traction.ConclusionsFive years after the STF began its work, the development of novel value measures continues to evolve. Although it is encouraging to see supporting empirical studies emerging, more are needed. Additional efforts are also needed to illustrate how the estimates can be used in the deliberative processes that are integral to health technology assessments.     

基于古今文献对经典名方中细辛毒性的有效避减探析

目的：通过研究细辛的相关文献,对影响细辛毒性的关键信息进行梳理,为经典名方中细辛的合理应用提供依据。方法：通过文献计量学的方式,搜集细辛的古今相关文献,分析细辛毒性与药物基原、用药部位、炮制方式、药物剂型、方药配伍、服药方法及患者体质因素之间的关系。结果：在经典名方的研发过程中,细辛在当归四逆汤、厚朴麻黄汤中的用量分别为9、6 g,煎煮时间应>120 min;细辛在辛夷散、三痹汤、大秦艽汤、清上蠲痛汤种的单次用量分别为0.8、1.2、0.9、1.1 g;当归四逆汤、厚朴麻黄汤、清上蠲痛汤等应选用辽细辛的根茎,辛夷散可选择汉城细辛的根茎。在药物的炮制上,当归四逆汤、厚朴麻黄汤、三痹汤、大秦艽汤四方中的细辛可选用酒制;辛夷散、清上蠲痛汤中的细辛可选用炒制;另外,细辛的毒性与药物的配伍和患者的体质等因素均有着密切的关系。结论：该研究通过梳理有关细辛毒性的文献资料,得出了影响细辛毒性的关键信息,探析了细辛毒性的有效避减方式,为包含细辛的经典名方的合理开发和安全应用提供了更为充分的依据。

Toward Better Data Dashboards for US Drug Value Assessments

ObjectivesTo explore the use of data dashboards to convey information about a drug’s value, and reduce the need to collapse dimensions of value to a single measure.MethodsReview of the literature on US Drug Value Assessment Frameworks, and discussion of the value of data dashboards to improve the manner in which information on value is displayed.ResultsThe incremental cost per quality-adjusted life-year ratio is a useful starting point for conversation about a drug’s value, but it cannot reflect all of the elements of value about which different audiences care deeply. Data dashboards for drug value assessments can draw from other contexts. Decision makers should be presented with well-designed value dashboards containing various metrics, including conventional cost per quality-adjusted life-year ratios as well as measures of a drug’s impact on clinical and patient-centric outcomes, and on budgetary and distributional consequences, to convey a drug’s value along different dimensions.ConclusionsThe advent of US drug value frameworks in health care has forced a concomitant effort to develop appropriate information displays. Researchers should formally test different formats and elements.
