    Inferior Gluteal Artery Perforator Flap for Closure of Sacral Defects after Pilonidal Sinus Surgery
    Bali, ZU; Ahmedov, A; Özkan, B; Mazican, M; Keçeci, Y
    Introduction: The aim of the current study was to introduce the use of the inferior gluteal artery perforator flap (IGAPF) as a new alternative surgical technique for closure of sacral defects after pilonidal sinus surgery. Patients and Methods: Inferior gluteal artery perforators were used on 15 male patients operated in the plastic and reconstructive surgery deportment of our tertiary care centers between March 2014 and May 2017. Age, size of the defect, duration of follow-up, complications, and recurrence rate were assessed. Results: The average age was 30.2 (range: 17-54) years, and the mean duration of follow-up was 8.2 (range: 7-16) months. No recurrence was detected within the follow-up period, and the only remarkable complication reported was total flap necrosis attributed to venous congestion in one patient. The mean size of the defects after excision was 21.6 cm(2). Conclusion: Our preliminary results imply that IGAPF can be a safe and effective alternative for closure of large defects after pilonidal sinus surgery. Further controlled trials on larger series are warranted to establish the advantages and disadvantages of this alternative technique.

    Reconstruction of burn contractures with free anterolateral thigh flap in various anatomic sites
    Bali, ZU; Özkan, B; Keçeci, Y; Ertas, N; Yoleri, L
    BACKGROUND: Burn contractures that cause a restriction in extremity movements have to be reconstructed. Free microvascular flaps are generally needed in cases of severe contractures. The ideal free flap for severe contracture defects has to have a large skin island without bulk and a long pedicle for preventing recurrence and tension-free adaptation. Anterolateral thigh flap (ALT flap) that meets these features has widely been used for several indications in reconstructive surgery. Usage of ALT flap in burn contracture was described for burn and axillary contractures in literature. In this study, the usage of free ALT flaps in various anatomic contracture sites was reported. METHODS: Fifteen free ALT flaps were performed in 14 (12 male, two female) patients with a mean age of 36.6. Burn contracture defects in neck, axilla, popliteal, cubital region, plantar foot and hand were reconstructed with ALT flap. RESULTS: No total flap loss was encountered. Distal flap necrosis was seen in one case. All patients had significant improvement in a range of motions. Recurrence in contracture was seen in one patient with hand flexor contracture due to lack of physical treatment. CONCLUSION: ALT flap can safely be used in various anatomic contracture sites. Suprafascial elevation of the flap can be preferred for better adaptation in the neck, hand and foot and prevention of bulky appearance.

    Objective: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population-specific growth charts for TS. Considering national and ethnic differences, we undertook this multicenter collaborative study to construct growth charts and reference values for height, weight and body mass index (BMI) from 3 years of age to adulthood for spontaneous growth of Turkish girls with TS. Methods: Cross-sectional height and weight data of 842 patients with TS, younger than 18 years of age and before starting any therapy, were evaluated. Results: The data were processed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for defined ages and to construct growth curves for height-for-age, weight-for-age and BMI-for-age of girls with TS. The growth pattern of TS girls in this series resembled the growth pattern of TS girls in other reports, but there were differences in height between our series and the others. Conclusion: This study provides disease-specific growth charts for Turkish girls with TS. These disease-specific national growth charts will serve to improve the evaluation of growth and its management with growth-promoting therapeutic agents in TS patients.

    Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. Results: The most common karyotype was 45, X (50.7%), followed by 45, X/46, XX (10.8%), 46, X, i(Xq) (10.1%) and 45, X/46, X, i(Xq) (9.5%). Mean age at diagnosis was 10.2 +/- 4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45, X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan.
