RESUMEN
The aim of the study is to identify the effects of in-brace correction on coronal spinal and thoracic cage parameters in individuals with idiopathic scoliosis (IS). The coronal spinal parameters [Cobb angle, apical vertebral rotation (AVR), lateral trunk shift, coronal alignment, biacromial slope and pelvic asymmetry] and the thoracic cage parameters [T1- 12 height, T1-S1 height, thoracic transverse diameter, and apical vertebral body-rib ratio (AVB-R)] of 89 child and adolescent patients were measured on posterior-anterior full-spine radiographs at pre-brace and in-brace conditions using Surgimap software. The initial in-brace correction (IBC) was calculated as a percentage decrease in the Cobb angle on the in-brace radiographs. The mean IBC rate for the primary curve was 37% (range = 10-100%). In the in- brace condition, the Cobb angle (p<0.001), AVR (p<0.001) and lateral trunk shift (p<0.001) decreased significantly; no statistically significant difference was found in the biacromial slope (p=0.713) and the coronal alignment (p=0.074). The T1-12 height and the T1-S1 height increased significantly (p<0.001) whereas the thoracic transverse diameter and the AVB-R decreased significantly (p<0.001). Unlike IBC rate was below 30% as IBC rate was above 30%, the T1-12 height (p<0.001) increased and the AVB-R decreased (p<0.001). The bracing improved the lateral trunk shift, the AVB-R, the thoracic and spine heights, but decreased the thoracic transverse diameter. The thoracic cage parameters may be better when the IBC rate is above 30%.

The aim of this study was to examine HIV sexual risk behaviours and perception of HIV risk among 1 095 students from the United States of America (US); Turkey and South Africa. Randomly selected students who were enrolled in general education courses completed a structured questionnaire. Results revealed statistically significant differences in specific HIV-related sexual behaviours among students from the three countries and among male and female students in each country. A higher percentage of US and South African students engage in HIV risky sexual behaviours compared with their Turkish counterparts; and a higher percentage of female students in the US and South Africa engage in HIV sexual risk behaviours compared with their male colleagues. A higher proportion of Turkish male students engaged in sexual risk behaviours compared with their female counterparts. The perception of HIV risk was low among US and Turkish students; and high among South African students. There was no agreement between engaging in risky sexual behaviour and self-perception of HIV risk among South African female students; while agreement was poor for US male and female students; Turkish male and female students; and South African male students. The observed optimistic bias needs to be considered in the design and implementation of HIV prevention programmes for these populations

OBJECTIVE: This study evaluated the content validity, internal consistency and stability of a questionnaire designed to assess the HIV/AIDS knowledge of young adults. METHODS: The questionnaire was administered on two occasions, within two week intervals, to 219 university students in the USA (n=66), Turkey (n=53) and South Africa (n=100). The psychometric instrument contained demographic information questions and 45 knowledge questions regarding the HIV virus, ways of transmitting it, symptoms of HIV/AIDS infection and methods of prevention. Factor analysis was conducted to assess construct validity; Cronbach alphas and Pearson's product moment correlation (r) were calculated to evaluate internal consistency and stability, respectively. RESULTS: The 45 knowledge questions produced a Kaiser-Meyer-Olkin (measure of sampling adequacy) value of 0.8133 and loaded on three factors with an overall Cronbach's alpha of 0.861. The r for the individual knowledge question was greater than 0.50 and the overall knowledge score was "almost perfect" (0.91; p<.001). For participating students from the USA, Turkey and South Africa, their r for the overall knowledge score was 0.80 (p<.001), 0.83 (p<.001) and 0.93 (p<.001), respectively. CONCLUSIONS: Our findings revealed that the instrument is highly stable and internally consistent. The availability of this instrument may enhance HIV intervention studies internationally.

Primary cancer of the vagina constitutes 1-2% of all malignant genital tract tumors in women. As one of the most complicated therapeutic problems in gynecological oncology, this disease had been deemed to be untreatable until the end of 1930s. Presently, as a result of technological improvements in radiotherapy and radical surgery, more favorable prognoses are known to be achieved even in advanced cases. In the present case, a woman with vaginal cancer and Stage IV massive uterovaginal prolapsus, which could not be repositioned under general anesthesia, was repositioned by surgical intervention prior to radiotherapy to avoid any potential vesicovaginal fistula formation. The cervix was bilaterally suspended to the pectineal ligaments by polypropylene mesh.

A 40-year-old woman with mucoepidermoid variant of adenosquamous carcinoma arising in dermoid cyst in left ovary is presented. The patient was staged as IC. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymph node sampling were carried out. The disease recurred in postoperative 12th month. To our best knowledge, this is 12th case of adenosquamous carcinoma in dermoid cyst and third case of mucoepidermoid variant of adenosquamous carcinoma in the literature.

The purpose of this study was to investigate the effects of a 4 week physiotherapy programme on patients who were given a spinal orthosis for neuromuscular scoliosis. This study was planned as a single group pre- and post-intervention repeated measures design. All patients were given a polyethylene spinal orthosis with an anterior opening. Fifteen (15) patients with neuromuscular diseases and a mean age of 12.46 years were evaluated. An exercises programme consisting of postural training, muscle strengthening and stretching exercises with special emphasis on respiratory exercises was given as an adjunct to orthotic treatment. The degree of impairment in forced vital capacity was 17.56% upon wearing an orthosis, it decreased to 9.28% following therapy (p < 0.05). There was also a statistically significant increase in muscle strength, balance duration and a significant decrease in limitation of range of motion. The results of the study imply that the conservative treatment of neuromuscular scoliosis should include an exercise programme as an adjunct to an orthosis, both to reduce the compromising effect of an orthosis on respiratory function and to support the patient's physical capacities.

Two siblings with nemaline myopathy were analysed. There was a general muscle weakness and lack of muscle strength that was more obvious in the proximal muscles. One could walk independently and one with minimal support. Patients developed a serial of postural adaptations. No correlation between muscle strength and functional level was found.
