Pneumatic femoral broaching in direct anterior approach hip arthroplasty

AimThe aim of this study is to report the safety and efficacy of the Woodpecker pneumatic broaching system in direct anterior hip arthroplasty.Methods649 primary elective anterior bikini total hip arthroplasties (THA) using Woodpecker broaching over a 5-year period were included. Patients undergoing a THA through a different surgical approach, revision THA or arthroplasties for hip fractures were excluded (n=219). Preoperative and postoperative Harris Hip Scores (HHS) and postoperative radiographs were analysed to identify femoral fractures and femoral component positioning. Complications and component survivorship until most recent follow-up were analysed.ResultsThe average time taken for femoral preparation using Woodpecker broaching system was 2.8 min (1.4–7.5 min) in both cemented and uncemented THAs. Radiographic analysis revealed 67.3% of the stems were placed in 0°–1.82° of varus and 32.7% placed in 0°–1.4° of valgus. Average HHS were 24.4 preoperatively, with significant improvements at 6 weeks (80.95), 6 months (91.91) and 12 months (94.18) of follow-up. Complications not directly attributed to Woodpecker broaching included three intraoperative femoral fractures (0.4%), three periprosthetic postoperative fractures (0.3%), two cases of stem subsidence (0.3%) and two wound infections (0.3%). At the most recent follow-up, the survivorship of the acetabular component was 99.7% and the femoral component was 99.1%, with mean follow-up of 2.9 years (0.5–5 years).ConclusionThe pneumatic Woodpecker device is a safe and effective alternative tool in minimally invasive direct anterior hip replacement surgery for femoral broaching performed on a standard table.

IMPROVEMENT OF THE TECHNOLOGICAL MODES OF PRODUCING DRY WHITE TABLE WINES

By using the classical technology of making dry white wines, which does not involve maceration of the pomace, we can produce standard table wines, light and delicate. This minimises such an objectionable factor as saturation of the wine with extra nitrogenous and phenolic substances and oxidative enzymes. On the other hand, this scheme gives a specific varietal aroma no chance to reveal itself more expressively. The paper overviews briefly the scientific works considering the modes of pomace maceration before fermentation and the use of enzyme preparations in the technology of white table wines. The physicochemical and sensory characteristics of wine materials from Rkatsiteli grapes grown in the south of the Mykolaiv Region have been analysed. This analysis has proved that standard white table wine materials can be obtained both by the traditional method (the so called ‘white’ method) and with the use of short-term maceration of the pomace. Macerating the pomace resulted in obtaining fuller, richer wine materials with a bright aroma and good body. It has been shown that to obtain bright and not too blunt wine materials, the most essential parameter of the maceration process is its low temperature. A pectolytic enzyme preparation used during maceration increased, to some extent, the mass concentration of phenolic substances, the reduced extract, the optical density, and the concentration of terpene alcohols. Besides, it allowed fuller revealing a wine’s aromatic profile. The research has resulted in establishing that there is regularity in how the concentration of terpene alcohols changes with different temperature conditions of steeping the pomace. It has been shown that the maximum concentration of terpenes responsible for the varietal aroma is best retained in wine materials when the maceration temperature is 5°C. A rise in the pomace maceration temperature to 20°C led to a decrease in the concentration of labile terpene alcohols, so it should be avoided in producing quality wines. Studying different maceration modes has allowed recommending a certain method to manufacture full-bodied, well-structured white table wines with a pronounced varietal aroma. This method involves adding the enzyme preparation Depectil CLARIFICATION to the pomace and macerating it for 12 hours at 5°C.

СТАТИСТИЧНА ОБРОБКА РЕЗУЛЬТАТІВ ЕКСПЕРИМЕНТАЛЬНОГО ДОСЛІДЖЕННЯ ЕФЕКТИВНОСТІ СИСТЕМИ ПІДГОТОВКИ МАЙБУТНIХ МОЛОДШИХ СПЕЦІАЛІСТІВ СЕСТРИНСЬКОЇ СПРАВИ

The purpose of article is in outlining the methods of proving the reliability of the results, obtained in the process of verifying the effectiveness of the updated system of vocational training of future junior specialists in nursing in colleges. In order to provide a comparative analysis of statistical data reflecting the results of the experimental study, the numerical indicators, obtained at the stages of input and final control were compared. The statistical data, reflected in tables and figures, indicate the levels of formation of each component of readiness for professional activity of future junior specialists in nursing, who studied in control and experimental groups. To prove the reliability of experimental results the methods of mathematical statistics, used in pedagogy, in particular, the calculation of Fisher criterion (F-criterion) and comparative analysis of its standard and empirical indicators were used. It has been determined that the indicator of Femp-CG with values from 1,21 to 1,24 is beyond probability, so a slight increase in the level of formation of each component and in general the readiness of future junior specialists in nursing for professional activity in CG is related to the conditions of traditional process of study. F-criterion for the experimental groups (Femp-EG) has the values from 1,39 to 1,44, which is within the indicators of the standard table. Therefore, the results of the study are reliable and confirm the reliability of the conducted research and experimental work. Thus, the effectiveness of training of future junior specialists in nursing in colleges depends on the purposeful implementation of the system of vocational training of future junior specialists in nursing. The results of experimental study are confirmed by reliable indicators, which are verified using the methods of mathematical statistics. We see further scientific researches in the continued improvement of the system of vocational training of future junior specialists in nursing in colleges in order of comprehensive formation of their readiness for professional activity.

Traction table versus standard table total hip arthroplasty through the direct anterior approach: a systematic review

Background: The direct anterior approach (DAA) for total hip arthroplasty (THA) was originally performed with a supine patient on a specialised traction table, but the approach can also be performed on a standard operating table. Despite cost and safety implications, there are few studies directly comparing these techniques and table choice remains largely surgeon preference. The purpose of this review was to compare the clinical outcomes and complication profiles of traction and standard table DAA for primary THA. Methods: The authors searched databases for relevant studies, screening in duplicate. Study quality was assessed using MINORS criteria or Cochrane Risk of Bias Tool. Data pertaining to patient demographics, clinical outcomes, and complications were abstracted. Results: Of 3085 initial titles, 44 studies containing a total 26,353 patients were included and analysed. Mean operative time was 70.9 ± 21.2 minutes for standard table ( n = 4402) and 100.1 ± 32.6 minutes for traction table ( n = 3518). Mean estimated blood loss was 382.3 ± 246.4 mL for standard ( n = 2992) and 531.7 ± 364.3 mL for traction table ( n = 2675). Intra-operative fracture rate was 1.3% for standard table ( n = 3940) and 1.7% for traction table ( n = 8386). Complication rates including revisions, dislocations and peri-prosthetic fractures were qualitatively similar between traction and standard table studies. Conclusion: Standard table and traction table DAA have similar outcomes and complications. Both techniques offer the short-term advantages of DAA when compared to other THA approaches. However, the standard table technique may offer perioperative advantages including decreased blood loss, shorter operative time, and fewer intraoperative fractures. In the context of rising global healthcare costs and lack of access to specialised orthopaedic traction tables, this review at minimum confirms the short-term safety of standard table DAA THA and prompts the need for future studies to directly compare these techniques.

Estimation of dental age in panoramic radiographs in children and adoloescents from 7-17 years through Demirjian method, Cuenca – Ecuador.

Age is an indicator of dental somatic maturation, of clinical importance in dentistry for planning the treatment of growing patients. The Demirjian method is the most widely disseminated to estimate dental age. With this method, numerous studies have been carried out in different ethnic groups, analyzing European, Asian and American children, among others. These results suggest possible differences in dental maturation patterns between different populations. The aim of the present study was to correlate the dental age, using the Demirjian method, with the chronological age according to gender in a group of children who attended the Radiological Center “Innova” located in Cuenca-Ecuador in the period 2012 - 2014, This study was descriptive, retrospective and analytical, in which a sample stratified by age and gender was selected, including 362 radiographs, of which 205 are female and 157 male. An inter-class correlation coefficient was obtained, as a measure of correlation between dental and chronological age, of 0.830 in the female gender and 0.801 in the male gender. In general, Demirjian’s method tended to underestimate dental age in girls and boys in a similar way. In conclusion, the results obtained in the present work do not coincide with many places in the world, that is, the dental age in this group was slightly lower in both girls and boys than the original Franco - Canadian sample. The obtained range of dental age is not similar to the chronological age but the degree of correlation between both is adequate to apply in our population, presenting itself in the same way according to gender, so a standard table for the population was elaborated Cuencana. We consider that the Demirjian method is applicable to this sample of children using the database proposed in the present investigation.
