    Objective: Steroid injections represent one of the simple treatment alternatives for simple bone cysts (SBC). The aim of this study was to evaluate the results of local steroid injections in the treatment of SBC. Methods: Seventeen patients (11 males, 6 females; mean age 12.4 years; range=2 to 39 years) with SBC were treated with injection of methylprednisolone acetate (MPA) with the use of the two-needle technique. The cysts were localized in the proximal humerus (n=6), the calcaneus (one patient had bilateral lesions) (n=2), proximal femur (n=7) and the tibia (n=2). Pathological fractures occurred in three patients before steroid injection. These three patients with pathological fractures were treated with injection of MPA after fractures healed. Each patient received a maximum of four injections at eight week intervals, each consisting of 40-160 mg of MPA. The patients were followed up with plain radiographs obtained in the first month, third month, sixth month, and at the end of a year. After the first year, patients were followed up with plain radiographs once a year. The mean follow-up duration was twenty two months (range=3 to 48 months). Cyst healing was assessed according to the modified Neer classification. Results: Treatment with MPA resulted in complete recovery in ten cysts (55%) and recovery with residual lesions in three cysts (17%). Three cysts (17%) did not respond to steroid treatment and two patients (11%) developed recurrence. The results were satisfactory (72%) in patients with complete recovery and partial recovery with residual lesions, and unsatisfactory in five patients (28%). The patients with recurrence were treated with curettage and grafting or cementation. No procedure-related complications were encountered. Conclusion: Our findings suggest that, the treatment with local steroid injection in SBC provides satisfactory results, thus this treatment with low morbidity can be applied to these patients before aggressive treatment.

    Evaluation of tularaemia courses: a multicentre study from Turkey
    (2014-12-01T00:00:00Z) ERDEM, H.; OZTURK-ENGIN, D.; YESILYURT, M.; Karabay, O.; ELALDI, NAZİF; Celebi, G.; KORKMAZ, N.; GUVEN, T.; Sumer, S.; TULEK, N.; Ural, O.; Yilmaz, G.; ERDINC, S.; Nayman-Alpat, S.; SEHMEN, E.; Kader, C.; SARI, N.; Engin, A.; CICEK-SENTURK, G.; ERTEM-TUNCER, G.; GULEN, G.; Duygu, F.; Ogutlu, A.; Ayaslioglu, E.; Karadenizli, A.; Meric, MELİHA; ULUG, M.; ATAMAN-HATIPOGLU, C.; Sirmatel, F.; CESUR, S.; COMOGLU, S.; KADANALI, A.; KARAKAS, A.; ASAN, A.; Gonen, I.; KURTOGLU-GUL, Y.; ALTIN, N.; OZKANLI, S.; YILMAZ-KARADAG, F.; CABALAK, M.; GENCER, S.; PEKOK, A.

    In this multicentre study, which is the largest case series ever reported, we aimed to describe the features of tularaemia to provide detailed information. We retrospectively included 1034 patients from 41 medical centres. Before the definite diagnosis of tularaemia, tonsillitis (n=653, 63%) and/or pharyngitis (n=146, 14%) were the most frequent preliminary diagnoses. The most frequent clinical presentations were oropharyngeal (n=832, 85.3%), glandular (n=136, 13.1%) and oculoglandular (n=105, 10.1%) forms. In 987 patients (95.5%), the lymph nodes were reported to be enlarged, most frequently at the cervical chain jugular (n=599, 58%), submandibular (n=401, 39%), and periauricular (n=55, 5%). Ultrasound imaging showed hyperechoic and hypoechoic patterns (59% and 25%, respectively). Granulomatous inflammation was the most frequent histological finding (56%). The patients were previously given antibiotics for 1176 episodes, mostly with -lactam/-lactamase inhibitors (n=793, 76%). Antituberculosis medications were provided in seven (2%) cases. The patients were given rational antibiotics for tularaemia after the start of symptoms, with a mean of 26.8 +/- 37.5days. Treatment failure was considered to have occurred in 495 patients (48%). The most frequent reasons for failure were the production of suppuration in the lymph nodes after the start of treatment (n=426, 86.1%), the formation of new lymphadenomegalies under treatment (n=146, 29.5%), and persisting complaints despite 2weeks of treatment (n=77, 15.6%). Fine-needle aspiration was performed in 521 patients (50%) as the most frequent drainage method. In conclusion, tularaemia is a long-lasting but curable disease in this part of the world. However, the treatment strategy still needs optimization.

    Is step-cut shortening osteotomy a better choice than transverse osteotomy for total hip arthroplasty for Crowe type III-IV hip dysplasia?
    (2024-01-01) Turgut N.; Erdem M.; ERDEM A. C.; BAYAM L.; Batar S.; Sağlam N.; GÜLABİ D.; ERDEM, AHMET CAN
    Introduction: Total hip arthroplasty for developmental hip dysplasia is a challenging surgery due to anatomic abnormalities. Crowe III and Crowe IV hip dysplasia generally necessitates a subtrochanteric shortening osteotomy. Transverse and step-cut osteotomy are the most common procedures for shortening of femur although there is still no consensus which one is a superior method. The objective of this study was to demonstrate whether transverse or step-cut osteotomy is superior in hips who undergo arthroplasty for high riding hip dysplasia. Hypothesis: Our hypothesis was that higher rates of union would be achieved in patients with Crowe III-IV hip dysplasia when the step-cut osteotomy was performed compared to transverse osteotomies. Material and methods: A total of 99 hips from 90 patients (9 bilateral, 81 unilateral; 79 female, 11 male), each with a minimum follow-up duration of two years, were included in this study. The hips were classified as Crowe III (n = 16) or IV (n = 83). All hips were implanted cementless. Transverse or step-cut osteotomy was chosen for osteotomy type. The clinical and functional outcomes were assessed using the Harris Hip Score (HHS), limb length discrepancy (LLD), and limping. The complications and management of these were noted. The union rates were compared between osteotomy types. Results: The mean age at surgery was 48.8 (range, 21–79 years). The follow-up period was 64.3 months in average (range, 24 to 192 months). The mean Harris Hip Score before surgery was 35.6 (range, 18–50), and increased to 88.1 (range, 61–98) points at the most recent follow-up. The preoperative leg length discrepancy (LLD) measured 5.3 cm (with a range of 3 to 6.8), while the postoperative LLD reduced to 0.8 cm (with a range of 0 to 1.6). There were a total of 38 complications in 35 patients out of 99 cases, resulting in a complication rate of 38.4%. The most frequent complication observed was intraoperative femoral fractures, occurring in 13 cases. Residual limping was seen in 73.7% of all. Step-cut osteotomy was performed in 64 hips (35 CDH stem [Zimmer Biomet, Warsaw, IN, USA], 29 Wagner Cone stem [Zimmer Biomet, Warsaw, IN, USA]) and, transverse in 35 hips (22 CDH, 13 Wagner Cone). Six hips had nonunion problem and all of them were operated with a step-cut osteotomy (z-score: –7.12 and p < 0.00001, Mann-Whitney U Test). Conclusion: Transverse osteotomy may be a better option while performing a shortening subtrochanteric level osteotomy for total hip arthroplasty for Crowe III-IV hips. Level of evidence: Level III; observational retrospective cohort study.
