Abstract
Objective: This retrospective study aimed at identifying opiate prescribing practices, the number of morphine milligram equivalents (MMEs) prescribed by orthopaedic and nonorthopaedic providers in patients with operatively treated isolated lower extremity fractures, and provide opiate prescribing recommendations. Methods: Patients older than 18 years with isolated lower extremity (unicondylar, bicondylar, tibial shaft, pilon, and ankle) fractures between 2005 and 2016 were identified. Prescribing information was obtained from the State Controlled Substance Monitoring Database. Descriptive statistics were calculated for each injury and plotted for MME use. Mann-Whitney and Wilcoxon tests were used for data analysis. To aid in clinical relevance, MMEs were converted to number of pills of oxycodone 10 mg (OC 10 mg). Results: Three hundred forty-one patients met our inclusion criteria. Mean age was 45 years; 56% (192/341) were men. Fortyseven percent (159/341) were prescribed opiates before their injury. Orthopaedic providers prescribed more opiates to patients with pilon fractures compared with unicondylar (P = 0.010), tibial shaft (P, 0.001), and ankle (P, 0.001) fractures. Bicondylar plateau fracture patients also received more opiates when compared with unicondylar (P = 0.001), tibial shaft (P, 0.001), and ankle (P, 0.001) fractures. Nonorthopaedic providers prescribed more opiates to patients with pilon fractures when compared with unicondylar (P = 0.006), bicondylar (P, 0.001), tibial shaft (P, 0.001), and ankle fractures (P = 0.006). Differences between orthopaedic and nonorthopaedic MMEs prescribed are significantly different for each injury type (, 0.05). Conclusions: Patients with pilon or bicondylar tibial plateau fractures are currently being prescribed more opiates when compared with other isolated fractures. We have developed an opiate prescription guideline based on what is being prescribed by orthopaedic providers.

Abstract
In this study the formation of the polygenetic High Tatra granitoid magma is discussed. Felsic and mafic magma mixing and mingling processes occurred in all magma batches composing the pluton and are documented by the typical textural assemblages, which include: mafic microgranular enclaves (MME), mafic clots, felsic clots, quartz-plagioclase-titanite ocelli, biotite-quartz ocelli, poikilitic plagioclase crystals, chemically zoned K-feldspar phenocrysts with inclusion zones and calcic spikes in zoned plagioclase. Geochemical modelling indicates the predominance of the felsic component in subsequent magma batches, however, the mantle origin of the admixed magma input is suggested on the basis of geochemical and Rb-Sr, Sm-Nd and Pb isotopic data. Magma mixing is considered to be a first-order magmatic process, causing the magma diversification. The cumulate formation and the squeezing of remnant melt by filter pressing points to fractional crystallization acting as a second-order magmatic process.
