Relationship between Coronal Alignment and Posterior Tibial Slope in the Lower Extremity

Abstract Purpose: To restore the normal axial alignment of the lower extremity is important in reconstructive knee surgery. The aim of this study was to evaluate lower-limb alignment and posterior tibial slope. Methods: Thirty-two male and 32 female outpatients aged 22 to 46 were recruited. A full weight-bearing anteroposterior radiograph of the entire lower limb was obtained for each subject. The axial alignment was measured based on the centers of the femoral head, knee, and ankle. The tibiofemoral (TF), tibial joint (TJ), and posterior tibial slope (TS) angles were determined. Results: The mean TF angle was more varus in women (177.8˚) than men (179.2˚), and the mean TJ angle was more medially inclined in women than men. Women had a greater TJ angle than men (93.3˚ vs. 91.6˚). The mean posterior TS was greater in men than women (16.0˚ vs. 12.5˚, p < 0.05), while the mean TS angle was greater in women (14.8˚) than men (12.3˚). Conclusion: Knee alignment and geometry vary among populations. In our study, the TF angle was varus among all participants. The knee joint was more medially inclined in women than men. And also the posterior TS was greater in women than men

Self-related differences in future time orientations

The aim of the present study was to explore patterns in Turkish university students' orientations toward the future, and to investigate how those orientations differed according to their self-types, as suggested by the Balanced Integration and Differentiation (BID) Model (Imamoglu, 1995; 1998; 2003). Accordingly, Attitudes toward the Future Scale, developed for the present purposes, Positive Future Expectations Scale (Imamoglu, 2001), Future Time Orientation Scale (Gjesme, 1979), and the BID Scale (Imamoglu, 1998; 2003) were administered to 295 Turkish university students (170 women, 125 men), who participated in the study. Comparisons of the data from the scales used suggested that it was meaningful to conceptualize the participants future orientations as Positive, Anxious, and Planned. In terms of self-related differences, respondents with related-individuated and separated-patterned self-types, proposed by the BID Model to represent the most balanced and unbalanced self-types, respectively, significantly differed from each other in that the former group seemed to have a more favorable outlook toward the future. Theoretical implications of the findings are discussed in the frame work of future attitudes and the BID Model

An unusual complication following total hip arthroplasty: median circumflex femoral artery pseudoaneurysm

We report a case of a pseudoaneurysm of the medial circumflex femoral artery that presented 4 months following cementless left total hip arthroplasty (THA). A successful embolization was achieved using super-selective catheterization and coil embolization. Arterial complications associated with THA are remarkably rare. Endovascular techniques have been shown to be effective and are considered a valid alternative to conventional surgery

Clinical and Radiological Outcomes of Total Knee Arthroplasty Performed with Midvastus and Medial Parapatellar Approaches in Obese Patients

Background. The use of total knee arthroplasty (TKA) for primary osteoarthritis of the knee has remarkably increased recently. We aimed to compare the clinical and radiological outcomes of TKA in obese patients (>30 kg/m2) operated with midvastus (MV) or medial parapatellar (MPP) approaches. Methods. This retrospective study was performed using data derived from 80 patients (70 women; 10 men) with an average age of 66.17 ± 5.42 (range: 54 to 77). Patients were allocated into 2 groups as for the type of approach conducted during TKA: group I (n = 41) underwent TKA by MV approach, while the MMP technique was used in group II (n = 39). Results. Demographic, clinical, and radiological parameters included age, side of involvement, sex, BMI, diameters of thigh and calf, length of incision, duration of operation, amount of bleeding and transfusion, duration of hospitalization and follow-up, complications, and range of motion, as well as Knee Society Score (KSS) and Knee Society Function Score (KSFS). Patients with a higher BMI (≥35 kg/m2) experienced more profound bleeding and needed more transfusion of erythrocyte suspension. The range of motion was more favorable in groups with BMI <35 kg/m2. The functional outcomes as reflected in KSS and KSFS were much better in patients with BMI <35 kg/m2. Conclusions. Our data indicated that obesity can adversely influence the clinical and radiological outcomes after TKA performed by both MV and MPP approaches. A careful analysis of patient characteristics and selection of appropriate operative procedures is critical. Further randomized, controlled trials on larger series must be designed to elucidate the relationship between obesity and therapeutic outcomes after TKA with different approaches

A new and simple procedure for the trace determination of mercury using differential pulse polarography and application to a salt lake sample

A new and simple differential pulse polarographic procedure was established for the trace determination of mercury(II). An indirect method had to be used since no polarographic peak can be observed for its direct determination. According to their standard potentials, the reaction between SO32- and Hg(II) was suitable. The peak height of sulfite at about -0.70 V (pH 6, 7) was sharp, high, and very reproducible, enabling the accurate determination of low concentrations of Hg(II). It was found that sulfite concentration had to be 3 times larger than mercury at pH 6, in order to have a quantitative reaction. The procedure is simple: to a known amount of sulfite in the polarographic cell (HAc, pH 6 or 7) is added an unknown Hg (II) sample. The Hg(II) concentration is calculated simply from the decrease in the sulfite peak after reaction with Hg(II). The limit of detection was 1 x 10(-6) M (S/N = 3) in this medium, which could not be obtained with most other mercury determination methods. The proposed new method exhibits high selectivity, sensitivity, reproducibility, and accuracy. It was successfully applied to synthetic samples and to a raw salt sample taken from a salt lake (closed basin) in Turkey. No considerable interference was observed from most common ions

Growth, health and behavioural traits of dairy calves fed acidified whole milk

Holstein Friesian calves reared in a new calf feeding program were assigned to diets of acidified (AM) or sweet (regular) milk (SM) to measure the effects of these diets on growth, health and feed efficiency. Calves' were fed AM or SM at 8% of their birth weight during 5 weeks. Two kinds of calf starters (18.5% and 17.6% crude protein) were offered to calves between birth and 4 months of ages and between 4 and 6 months of ages respectively. Weights at weaning, 4 and 6 months of ages and weight gains between various stages of the growth were not significantly affected by feeding of AM or SM. Gains in body measurements and feed efficiency values were also not significantly different among treatment groups. However, faecal consistency score and calf days with scours were significantly lower for calves fed AM compared with those consumed SM. Only frequency of milk intake among behavioural traits was significantly influenced by acidification of milk. Overall results of. the study suggested that feeding of AM resulted in beneficial effect on the lowering incidence of diarrhoea in young calves without causing an adverse influence on the growth and feed efficiency parameters

A case report of osteoblastoma on the distal phalanx of the ring finger successfully treated with curettage and polymethylmethacrylate filling

Background: Osteoblastoma is an aggressive benign tumor whose presentation varies with location and size. This rare bone tumor is thus difficult to diagnose particularly when it occurs outside its most common location – the vertebral column and long bones. Case: We report a case of osteoblastoma of the fourth distal phalanx of the left hand in an 18-year-old male, presented with pain and swelling and treated with curettage and polymethylmethacrylate filling followed by immobilization by a cast, which was opened 10 days later to start physical therapy. Patient was pain-free, recovered full function of his finger, and remained without pain at one month post-surgery. The finger was monitored closely for two years; sequential films showed a radiopaque interface and no evidence of local recurrence. Conclusion: This is the first report of osteoblastoma on the distal phalanx. The possibility of osteoblastoma should be considered in cases of pain and swelling of phalanx, and if diagnosed, curettage and polymethylmethacrylate filling may be the treatment of choice
