Summary Objective: To increase awareness on the severe impact of the nutcracker syndrome in women with undiagnosed disease. Patients and methods: We reviewed the medical literature and analyzed six representative series with 73 patients with nutcracker syndrome. Women with left flank pain, dyspareunia, dysuria, dysmenorrhea, micro- or macrohaematuria and pelvic congestion symptoms, should be carefully investigated for evidence of meso aortic left renal vein compression. A good number of our colleagues do not believe in the existence of the nutcracker syndrome and send these patients in a long pilgrimage in search of someone who can help them to get relief to their pain. New and improved imaging techniques can assist in the diagnosis but retrograde reno-gonadal phlebography and renocaval gradient are the most reliable diagnostic tools. Results: Among an assortment of treatment techniques, renal vein transposition and endovenous stenting were the two most commonly used procedures. There are no long term studies on renal vein stenting in children and young adults. Its use in these cases should be carefully considered. The nutcracker syndrome may present with pelvic congestion symptoms and its diagnosis missed. The patient's age, severity of symptoms and haemo dynamic renal studies should guide the treatment. Conclusion: An increased awareness of the existence of the nutcracker syndrome may prevent many unfortunate undiagnosed women from spending many months and often years of suffering.

The Relationship

Цель обзора - анализ современных данных литературы о нарушении внутриклеточных сигнальных путей, играющих ведущую роль в развитии менингиом, генетических и молекулярных профилях данной группы опухолей. К настоящему времени изучено множество аберрантных сигнальных внутриклеточных путей, которые играют важнейшую роль в развитии менингиом головного мозга. Четкое понимание поврежденных внутриклеточных каскадов поможет изучить влияние генетических мутаций и их эффектов на менингиомогенез. Подробное исследование генетического и молекулярного профиля менингиом позволит сделать первый уверенный шаг в разработке более эффективных методов лечения данной группы интракраниальных опухолей. Хромосомы 1, 10, 14, 22 и связанные с ними генные мутации ответственны за рост и прогрессию менингиом. Предполагается, что только через понимание данных генетических повреждений будут реализованы новейшие эффективные методы лечения. Будущая терапия будет включать в себя комбинации таргетных молекулярных агентов, в том числе генную терапию, малые интерферирующие РНК, протонную терапию и другие методы воздействия, как результат дальнейшего изучения генетических и биологических изменений, характерных для менингеальных опухолей. Meningiomas are by far the most common tumors arising from the meninges. A myriad of aberrant signaling pathways involved with meningioma tumorigenesis, have been discovered. Understanding these disrupted pathways will aid in deciphering the relationship between various genetic changes and their downstream effects on meningioma pathogenesis. An understanding of the genetic and molecular profile of meningioma would provide a valuable first step towards developing more effective treatments for this intracranial tumor. Chromosomes 1, 10, 14, 22, their associated genes, have been linked to meningioma proliferation and progression. It is presumed that through an understanding of these genetic factors, more educated meningioma treatment techniques can be implemented. Future therapies will include combinations of targeted molecular agents including gene therapy, si-RNA mediation, proton therapy, and other approaches as a result of continued progress in the understanding of genetic and biological changes associated with meningiomas.

Stage Conversion

Herein we describe the development and application of a method for the mild, late-stage conversion of primary sulfonamides to several other other functional groups. These reactions occur via initial reductive deamination of sulfonamides to sulfinates via an NHC-catalyzed reaction of transiently formed <i>N</i>-sulfonylimines. The method described here is tolerant of nearly all common functional groups, as exemplified by the late-stage derivatization of several complex pharmaceutical compounds. Based on the prevalence of sulfonamide-containing drugs and building blocks, we have developed a method to enable sulfonamides to be applied as versatile synthetic handles for synthetic chemsitry.

At Risk Adolescents

Inflammatory markers including C-Reactive Protein (CRP) are increasingly used within research and clinical settings. Yet, varying methodologies for cleaning immunoassay data with out of range (OOR) samples may alter characteristic levels of CRP, thereby obscuring interpretation and reliability. This study investigated the influence of eight immunoassay OOR data treatment techniques on salivary CRP (sCRP) samples from at-risk adolescents. Participants from the ‘Sleep and Education: learning New Skills Early’ (SENSE) Study were 86 adolescents at-risk for depression (50 female), aged 14.29 years (SD=1.04). ANOVA results showed no statistically significant differences in average morning (F(7, 590)=1.24, p=.28) and evening (F(7, 599)=1.29, p=.25) values produced by each OOR data cleaning technique. However, varying techniques produced differences in the magnitude of Pearson’s correlations between consecutive saliva samples (r’s between .27 – .78), and influenced the significance of a sCRP diurnal pattern; two techniques produced statistically higher morning than evening sCRP levels (t(85)=2.70, p=.01 and t(85)=2.67, p=.01), whereas six techniques failed to find statistical differences between morning and evening sCRP levels (p’s &gt;.05). Varying techniques also produced statistically divergent associations between sCRP and age and depressive symptoms. Results from this study provide evidence for the temporal stability of sCRP among adolescents, show winsorization as an effective OOR data management technique, and highlight the influence of methodological decisions in cleaning salivary biomarker data and the need for consistency within the field.
