RESUMO
AIM: This retrospective study aimed to evaluate surgical outcomes and identify influential factors in pediatric femoral neck fractures. MATERIALS AND METHODS: A total of 25 hips from 23 pediatric patients who underwent surgical intervention for femoral neck fractures were included. Data encompassing patient demographics, fracture types, surgical techniques, complications, and follow-up outcomes were analyzed retrospectively. Factors such as fracture displacement, timing of surgery, fixation methods, and reduction quality were assessed concerning postoperative complications. RESULTS: Falling from a height accounted for 48% of the trauma mechanisms, and avascular necrosis (AVN) was the most prevalent complication (4 hips). Although fracture displacement, bad reduction quality, and delayed surgery were more common among complicated cases, statistical significance was not attained. The study noted an association between presence of avascular necrosis and worse clinical results(rho: 0.428, p: 0.05, CI: 95%). CONCLUSION: Surgical treatment yielded favorable clinical outcomes; however, limitations due to the study's retrospective design, limited sample size, and single-center approach underscore the necessity for larger multicenter studies. Our findings emphasize the need for comprehensive investigations to better understand and manage pediatric femoral neck fractures, especially regarding factors influencing AVN and long-term outcomes.
RESUMO
Introduction: Juvenile idiopathic arthritis ( JIA) is a persistent autoimmune-inflammatory disease that affects children younger than 16. Aggressive synovitis of the hip may cause joint destruction, hip protrusion, erosion, pseudosubluxation, dysplasia, and osteoarthritis. Subluxation of the hip had been reported previously. However, dislocation of the hip in JIA is an extremely rare situation, and only two cases have been reported up to date. Reduction of the dislocated hip has to be performed in any way. However, there is no algorithm to be followed for the treatment of hip dislocations caused by JIA. Case Presentation: In this study, we presented two cases of hip dislocation caused by JIA.Case 1: An 11-year-old boy had JIA and chronic recurrent multifocal osteomyelitis (CRMO). X-rays and computed tomography (CT) revealed a posterior dislocation of the left hip. An urgent operation was planned for the reduction of the hip. Avascular necrosis, dysplasia, or erosions were not evident at the last follow-up.Case 2: An 11-year-old girl was referred to the hospital with excessive left hip pain starting 24 h ago. A limited synovectomy with joint irrigation was performed. However, pathological examination of the synovium showed chronic inflammation consistent with JIA. On the post-operative 10th day, the patient was consulted for an increase in hip pain and deformity of the left hip. X-rays and MRI revealed posterior dislocation of the left hip with synovial hypertrophy. An urgent operation was planned. The hip could be reduced under anesthesia with mild traction, and a pelvipedal cast was applied only for 3 weeks. Avascular necrosis, dysplasia, destruction, or erosions were not evident at the last follow-up. Conclusion: For early diagnosed patient reduction under anesthesia and medial soft-tissue contracture release; for late diagnosed patient medial soft-tissue contracture release, capsulotomy and synovectomy were effective to prevent destruction and early degenerative changes of the hip joint for treatment of dislocation caused by JIA.
RESUMO
OBJECTIVES: Glucocorticoids (GC) are widely accepted as the standard first-line treatment for giant cell arteritis (GCA). However, relapse rates are reported up to 80% on GC-only protocol arms in controlled trials of tocilizumab and abatacept in 12-24 months. Herein, we aimed to assess the real-life relapse rates retrospectively in patients with GCA from Turkey. METHODS: We assembled a retrospective cohort of patients with GCA diagnosed according to ACR 1990 criteria from tertiary rheumatology centres in Turkey. All clinical data were abstracted from medical records. Relapse was defined as any new manifestation or increased acutephase response leading to the change of the GC dose or use of a new therapeutic agent by the treating physician. RESULTS: The study included 330 (F/M: 196/134) patients with GCA. The mean age at disease onset was 68.9±9 years. The most frequent symptom was headache. Polymyalgia rheumatica was also present in 81 (24.5%) patients. Elevation of acute phase reactants (ESR>50 mm/h or CRP>5 mg/l) was absent in 25 (7.6%) patients at diagnosis. Temporal artery biopsy was available in 241 (73%) patients, and 180 of them had positive histopathological findings for GCA. For remission induction, GC pulses (250-1000 methylprednisolone mg/3-7 days) were given to 69 (20.9%) patients, with further 0.5-1 mg/kg/day prednisolone continued in the whole group. Immunosuppressives as GC-sparing agents were used in 252 (76.4%) patients. During a follow-up of a median 26.5 (6-190) months, relapses occurred in 49 (18.8%) patients. No confounding factor was observed in relapse rates. GC treatment could be stopped in only 62 (23.8%) patients. Additionally, GC-related side effects developed in 64 (24.6%) patients, and 141 (66.2%) had at least one Vasculitis Damage Index (VDI) damage item present during follow-up. CONCLUSIONS: In this first multi-centre series of GCA from Turkey, we observed that only one-fifth of patients had relapses during a mean follow-up of 26 months, with 76.4% given a GC-sparing IS agent at diagnosis. At the end of follow-up, GC-related side effects developed in one-fourth of patients. Our results suggest that patients with GCA had a low relapse rate in real-life experience of a multi-centre retrospective Turkish registry, however with a significant presence of GC-associated side effects during follow-up.
RESUMO
ABSTRACT Purpose: To evaluate the corneal and anterior chamber morphology in phakic eyes with noninfectious intraocular inflammation. Methods: This study included 59 eyes with active uveitis, 62 with inactive uveitis, and 95 healthy eyes. Corneal endothelial cell density, hexagonal cell ratio, coefficient of variation (CV), corneal thickness and volume, maximum keratometry, and anterior chamber volume and depth (ACD) measurements were performed using a specular microscope and Pentacam HR. Results: The mean duration of uveitis was 24.6 ± 40.5 (0-180) months. The mean number of uveitis attacks was 2.8 ± 3.0 (1-20). Coefficient of variation was significantly higher in the active uveitis group compared with inactive uveitis group (p=0.017, Post Hoc Tukey). Anterior segment parameters other than coefficient of variation were not significantly different between active/inactive uveitis and control groups (p>0.05). Multiple linear regression analysis showed that coefficient of variation was greater in active uveitis compared with inactive uveitis after adjusting for the duration of uveitis, type of uveitis, having a rheumatologic disease, and having immunosuppressive treatment (p=0.003). The duration of uveitis and number of attacks were not significantly correlated with ocular parameters (p>0.05, Spearman's correlation). The difference in parameters was not significant based on uveitis type (p>0.05). Conclusions: Coefficient of variation was higher in eyes with active uveitis than that in eyes with inactive uveitis, whereas corneal endothelial cell density and anterior chamber morphology did not significantly differ between active/inactive uveitis and control groups.(AU)
RESUMO Objetivo: Avaliar a morfologia da córnea e da câmara anterior em olhos fácicos com inflamação intraocular não infecciosa. Métodos: Esse estudo incluiu 59 olhos com uveíte ativa, 62 olhos com uveíte inativa e 95 olhos saudáveis. A densidade de células endoteliais da córnea, a proporção de células hexagonais, o coeficiente de variação, o volume e a espessura da córnea, a ceratometria máxima e o volume e profundidade da câmara anterior foram medidos com um microscópio especular e uma Pentacam HR. Resultados: A duração média da uveíte foi de 24,6 ± 40,5 (0-180) meses. O número médio de crises de uveíte foi de 2,8 ± 3,0 (1-20). O coeficiente de variação foi significativamente maior no grupo com uveíte ativa do que no grupo com uveíte inativa (p=0,017, Tukey post-hoc). Não houve diferença significativa nos demais parâmetros do segmento anterior entre os grupos com uveíte ativa, com uveíte inativa e controle (p>0,05). A análise de regressão linear múltipla demonstrou que o coeficiente de variação foi maior na uveíte ativa do que na uveíte inativa, após ajustes para a duração e tipo de uveíte e a presença ou não de doença reumática e de tratamento imunossupressor (p=0,003). A duração da uveíte e o número de crises não demonstraram correlação significativa com os parâmetros oculares (p>0,05, correlação de Spearman). A diferença nos parâmetros não demonstrou correlação significativa com o tipo de uveíte (p>0,05). Conclusões: O coeficiente de variação foi maior nos olhos com uveíte ativa do que naqueles com uveíte inativa, ao passo que a densidade de células endoteliais e a morfologia da câmara anterior não mostraram diferenças significativas entre os grupos com uveíte ativa, com uveíte inativa e controle.(AU)

INTRODUCTION: Efforts to prevent iatrogenic neurovascular injuries with humeral intramedullary nailing lead to design new implants and inside to out distal locking technique using an endopin aims to provide a safer screw application. InSafeLock (TST, Istanbul, Turkey) humeral nail have been recently developed to minimize the possible screw related complications. The anatomical relationship between locking screws and neurovascular structures with the application time were compared between Trigen Humeral Nail (Smith and Nephew, Memphis, USA) and InSafeLock Humeral Nail. HYPOTHESIS: InSafeLock humeral nail would be safer than Trigen Humeral nail in terms of neurovascular injury. MATERIALS AND METHODS: Seven cadavers were used with both shoulders and surgical application of two nails was performed as the manufacturer guide. An Insafelock humeral nail was used for each right humerus and a Trigen humeral nail was used for each left humerus. Once the nails were placed, proximal and distal region of the nails were dissected to evaluate the relationship between screws and adjacent anatomical structures. The duration of the each screw was assessed via a stopwatch. RESULTS: No significant finding was noted for the relationship between the neurovascular structures and proximal screws in two groups (p<0.05). The distal locking of the InSafeLock humerus nail had a shorter application time and no neurovascular damage was recorded. DISCUSSION: The newly developed Insafelock humerus nails are at least as safe and effective as current humeral nails available on the market. Additional benefits include the preservation of neurovascular structures, as the Insafelock humerus nail does not require the use of an extra incision. Furthermore, surgical time is significantly shorter with using distal endopin. LEVEL OF STUDY: III, controlled laboratory study.

BACKGROUND/OBJECTIVES: We evaluated the clinical characteristics of patients with haematological malignancies at our centre who were diagnosed with leukaemia cutis (LC). In addition, we describe the spectrum of other skin lesions, including, secondary skin malignancies and nonspecific benign skin lesions in haematological malignancy patients. METHODS: We defined 58 skin lesions that developed in 54 inpatients hospitalised in the Department of Haematology, Trakya University Medical Faculty, Turkey. All skin lesions that developed in inpatients between 2006 and 2012 had been evaluated by a dermatologist. The patients' clinical features, skin biopsy results and therapies were obtained from hospital files. The diagnosis of LC was based on clinical features and histopathological examinations of the skin biopsy. RESULTS: There were 11 patients with LC. Six (54.5%) had acute myeloblastic leukaemia. In nine patients (82%), LC was present at the initial presentation. Secondary skin malignancy was detected in 11 patients (five basal cell carcinoma, four Kaposi's sarcoma, one squamous cell carcinoma, one malignant melanoma); and malignancy was present in two patients (18%) at the initial presentation. Nonspecific benign skin lesions, the most frequent of which were drug eruptions, were determined in 32 of our patients. LC had a significantly higher likelihood of being present at initial presentation than other skin lesions (P < 0.01). The median survival in LC patients was quite short (4.5 months). CONCLUSIONS: LC was usually diagnosed at the initial presentation of the patient or during the early course of the disease. Having LC was a poor prognostic factor.

Hemorrhage is a frequent complication in patients with acute leukemias as a result of chemotherapy-induced myelosuppression. Gastrointestinal bleeding in thrombocytopenic patients carries a high mortality. Patients are generally managed with red blood cell, platelet suspensions, and fresh frozen plasma; and sometimes with pharmacologic and endoscopic interventions. If these therapeutic measures fail, patients might be treated with hemostatic drugs, one example of which is recombinant activated factor VII (rFVIIa). This drug is recommended for all kinds of bleeding in hemophiliacs with inhibitors; it is also being used for the treatment of bleeding in thrombocytopenia and platelet function disorders. We present our 44-year-old female patient who had gastrointestinal system bleeding after remission induction therapy for acute myeloid leukemia. Thrombocytopenia was refractory to apheresis platelets; and gastrointestinal bleeding could be controlled only after the administration of a single dose (35 microg/kg, total dose 2.4 mg) of rFVIIa. Our experience indicates that rFVIIa might be a novel treatment alternative in massive bleeding in leukemic patients with thrombocytopenia or platelet function disorders.
