The Relationship between Scoliosis Surgery and Quality of Life

Scoliosis is known as "curvature of the spine" and early diagnosis is very important. It can provide a great advantage to individuals when appropriate treatment or surgery. Today, the surgical treatment of scoliosis curvatures is very successful and an aesthetic and beautiful appearance is formed after the operation. In addition to the aesthetically beautiful appearance, the pain of individuals decreases, and their quality of life increases. This study was conducted to reveal how the quality of life of patients who had scoliosis surgery changed. The population of the study consisted of 121 patients who underwent scoliosis surgery in a private hospital in Istanbul between September 2009 and October 2010. The ages of these patients were 8 and over and 99 patients participated in the study. Data were collected with two tools, namely the information form and the Scoliosis Research Society-22 (SRS-22) scale. The independent variables of the study were demographic and disease characteristics of the cases; The dependent variable was quality of life scores. Information form and scale were applied at least 3 months after scoliosis surgery. The data were evaluated by percentage distributions, t-tests, and ANOVA analysis in a computer environment. A total of 99 patients participated in the study. Of these, 78 people were 78.8% women, and 21 people were 21.2% men. Their ages were between 8 and 20 years old. 62 people, mostly between the ages of 14-19, were 62.2%. 7 people aged at least 20 years and older were 7.1%. Mean SRS-22 and its sub-dimensions, Pain mean 21.84± 2.81, General Appearance Evaluation mean 17.66± 4.69, Spinal Function means 2 0.25± 3.64, Mental health mean 19.46± 2 The mean treatment satisfaction was found to be 9.26± 1.01, and the mean of the SRS-22 scale was 88.47± 10.68. When male and female patients were compared according to the general total mean score, the mean score of the female patients was found to be significantly higher than the mean score of the male patients. There was no difference between the groups in terms of age, education level, number of siblings, consanguineous marriage, place of residence, family type, chronic illness, and sports. The mental health sub-dimension scores of SSK patients were found to be statistically significantly higher than those of bonding and paid patients. Except for the satisfaction with the treatment sub-dimension, it was determined that the mean score of the patients with free movement was significantly higher than the mean score of the patients with partially restricted movement. The mean score of patients with scoliosis in relatives was found to be statistically significantly lower in terms of pain and spinal functions, compared to the mean score of patients whose relatives did not have scoliosis

Earthquake and ambient vibration monitoring of the steel frame UCLA Factor building

Dynamic property measurements of the moment-resisting steel-frame University of California, Los Angeles, Factor building are being made to assess how forces are distributed over the building. Fourier amplitude spectra have been calculated from several intervals of ambient vibrations, a 24-hour period of strong winds, and from the 28 March 2003 Encino, California (M_L =2.9), the 3 September 2002 Yorba Linda, California (M_L=4.7), and the 3 November 2002 Central Alaska (M_w=7.9) earthquakes. Measurements made from the ambient vibration records show that the first-mode frequency of horizontal vibration is between 0.55 and 0.6 Hz. The second horizontal mode has a frequency between 1.6 and 1.9 Hz. In contrast, the first-mode frequencies measured from earthquake data are about 0.05 to 0.1 Hz lower than those corresponding to ambient vibration recordings indicating softening of the soil-structure system as amplitudes become larger. The frequencies revert to pre-earthquake levels within five minutes of the Yorba Linda earthquake. Shaking due to strong winds that occurred during the Encino earthquake dominates the frequency decrease, which correlates in time with the duration of the strong winds. The first shear wave recorded from the Encino and Yorba Linda earthquakes takes about 0.4 sec to travel up the 17-story building

Large N limit of SO(N) scalar gauge theory

In this paper we study the large $N_c$ limit of SO(N_c) gauge theory coupled to a real scalar field following ideas of Rajeev. We see that the phase space of this resulting classical theory is Sp_1(H)/U(H_+) which is the analog of the Siegel disc in infinite dimensions. The linearized equations of motion give us a version of the well-known 't Hooft equation of two dimensional QCD.Comment: 16 pages, no figure

Unexpectedly high prevalence of sarcoidosis in a representative U.S. Metropolitan population

SummaryThe prevalence of sarcoidosis in the United States is unknown, with estimates ranging widely from 1 to 40 per 100,000. We sought to determine the prevalence of sarcoidosis in our health system compared to other rare lung diseases and to further establish if the prevalence was changing over time. We interrogated the electronic medical records of all patients treated in our health system from 1995 to 2010 (1.48 million patients) using the common ICD9 codes for sarcoidosis (135), lung cancer (162), and several other lung diseases characterized, like sarcoidosis, as “rare lung diseases”. The patient demographic information (race, gender, age) was further analyzed to identify signature data patterns. The prevalence of sarcoidosis in our health system increased steadily from 164/100,000 in 1995 to 330/100,000 in 2010, and this trend could not be ascribed simply to changes in patient demographics or patient referral patterns. We further estimate that the prevalence of sarcoidosis exceeds 48 per 100,000 in Franklin County, Ohio, the demographic profile of which is nearly identical to that of the U.S. Sarcoidosis prevalence increased over time relative to lung cancer, a benchmark disease with stable disease prevalence, and exceeded that of other rare lung diseases. We postulate that the observed 2-fold increase in sarcoidosis disease prevalence in our health system is primarily related to improved detection and diagnostic approaches, and we conclude that the actual prevalence of sarcoidosis in central Ohio greatly exceeds current U.S. estimates
