Background: Nowadays, ionizing radiation is increasingly used in medicine. One of the most frequent X-ray examinations is pelvic radiography. Gonads are susceptible in the pelvic area. Gonadal shielding (GS) is a useful method to reduce the received dose by gonads. Despite the benefits of using gonadal shielding, it is rarely used by radiographers. Methods: This cross-sectional study was carried out in ten governmental hospitals with 300 radiographs. Results: The radiographers’ knowledge of using GS had a value equal to 59.1%. However, the radiographers did not have enough information on the subject, although their awareness about the significance of GS was acceptable. Conclusions: Although the radiographers believed in the necessity of using GS for pelvic, abdominal, and spine examinations, they used no shields.

Background. Radiation using conventional X-ray is associated with exposure of radiosensitive organs and typically requires the use of protection. This study is aimed at evaluating the use of bismuth shielding for radiation protection in pediatric pelvic radiography. The effects of the anteroposterior and lateral bismuth shielding were verified by direct measurements at the anatomical position of the gonads. Methods. Radiation doses were measured using optically stimulated luminescence dosimeters (OSLD) and CIRS ATOM Dosimetry Verification Phantoms. Gonad radiographs were acquired using different shields of varying material (lead, bismuth) and thickness and were compared with radiographs obtained without shielding to examine the effects on image quality and optimal reduction of radiation dose. All images were evaluated separately by three pediatric orthopedic practitioners. Results. Results showed that conventional lead gonadal shielding reduces radiation doses by 67.45%, whereas dose reduction using one layer of bismuth shielding is 76.38%. The use of two layers of bismuth shielding reduces the dose by 84.01%. Using three and four layers of bismuth shielding reduces dose by 97.33% and 99.34%, respectively. Progressively lower radiation doses can be achieved by increasing the number of bismuth layers. Images obtained using both one and two layers of bismuth shielding provided adequate diagnostic information, but those obtained using three or four layers of bismuth shielding were inadequate for diagnosis. Conclusions. Bismuth shielding reduces radiation dose exposure providing appropriate protection for children undergoing pelvic radiography. The bismuth shielding material is lighter than lead, making pediatric patients more comfortable and less apt to move, thereby avoiding repeat radiography.

Abstract Objective The aim of this study was to assess the short-term clinical outcome in dogs following a hip hemi-arthroplasty for the treatment of primary pathological disorders of the hip and as a salvage procedure following failure of the cup component of a total hip replacement. Materials and Methods Medical records of dogs that had a unilateral hip hemi-arthroplasty performed between 2015 and 2020 were reviewed. Data collected included follow-up orthopaedic examinations performed at 0, 2, 8 and 52 weeks postoperatively, pelvic radiography at 0, 8 and 52 weeks postoperatively and an owner questionnaire (Helsinki chronic pain index [HCPI]). Results Eleven unilateral hip hemi-arthroplasty procedures were identified. The median age at time of surgery was 3.6 years (8 months–10 years) and the median follow-up time was 13 months (range: 2 months–3 years). The HCPI for all dogs at follow-up was median 8 ± 7.30 (range: 5–25). Total HCPI was < 12 for 7/10 dogs and ≥ 12 for 3 dogs. Pelvic radiographs at 1 year confirmed osteointergration of the femoral stem implant and no evidence of implant subsidence or progression of osteoarthritis. However, there was some evidence of mild lucency of the acetabular bed around the prosthetic femoral head and mild peri-acetabular sclerosis in four cases. Conclusion Hip hemi-arthroplasty provides a clinically acceptable treatment for disabling disease of the coxofemoral joint with 10/11 patients achieving acceptable short-term clinical function. Long-term assessment of the hip hemi-arthroplasty and comparison with total hip replacement is indicated.

Bladder exstrophy (BE) is a very rare congenital abnormality, especially in girls. We reported a 17-year-old girl with protruded bladder and urinary incontinence. Her vaginal orifice appeared stenotic and shifted anteriorly. She had an incomplete labia minora, short perineum, and anterior displacement of the anus. The pelvic radiography showed a pubic diastasis with a manta ray sign, and the ultrasonography examination showed a bicornuate uterus. She had undergone a functional reconstruction surgery with cystectomy, ileal conduit, appendectomy, and vaginoplasty along with the advancement of abdominal flap reconstruction with multiple Z-plasty. Functionally, she was able to urinate through the ileal conduit comfortably, had a regular menstrual cycle with minimal pain, had a wider vaginal canal, and had a smooth blood flow. Aesthetically, she had a good lower abdomen appearance, remained dry, and had an odorless urine. In clinical practice, this rare case report can provide additional knowledge and management of the same cases with effective results.

Background:Structural change within pubic symphysis (PS) occurs in 20–25% of patients with spondylarthritis (SpA). It occurs in all developmental stages, even in the early stages of the disease. Changes in the symphysis can sometimes precede spine and sacroiliac involvement. Radiological findings in PS were poorly described in the SpA, especially on its non-radiographic form (nr-axSpA).Objectives:We aimed in this study to evaluate pubic symphyseal features in patients with a confirmed diagnosis of nr-axSpA and to assess the correlation of these changes with clinical and imaging features of nr-axSpA in these patients. We also focused on the relationship between parity and radiographic changes in pubic symphysis (PS).Methods:We retrospectively reviewed the data of 40 patients diagnosed with nr-axSpA according to the ASAS criteria. Radiological-morphological changes of PS were assessed in pelvic radiography by two distinct rheumatologists. Grading symphysial involvement was made as follow: scores ranged from 0-4 per reading: grade 0 = normal; grade 1 = subtle irregularity and/or subchondral sclerosis, grade 2 = clear erosions, 3 = marked sclerosis, grade 4 = ankylosis.For all patients, we calculated the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the BASRI (Bath Ankylosing Spondylitis Radiology Index).For all patients, we recorded the sacroiliac changes showed by the previous pelvic radiography and/or the pelvic scanner and/or by magnetic resonance imaging (MRI).Results:We enrolled forty patients with a sex-ratio H/F=1/3. Mean age of patients at diagnosis was 39,9 +/- 10,8 [17-59]. Forty percent of patients had peripheral enthesitis, and 45% had peripheral arthritis. BASDAI mean score was 4,63 +/- 0,9 [0-8,6]. HLA B-27 was present in 32,3% of cases. We noted radiographic changes in PS in 37,5% (15 patients): grade 1 (n=1), grade 2 (n=10), grade 3 (n=3) and grade 4 (n=1). There was not a significant difference between the sex group (p=0,85). A comparison of 2 groups (women with 3 children or more and women with less than 3 children) concluded that childbirth did not modify PS changes (p=0,9). Also, PS changes did not differ with age (p=0,5). There was no correlation between the BASRI value with the presence of PS changes nor with its grades (p=0,5 and p=0,89, respectively). Also, disease activity did not influence the PS involvement (p=0,4). Radiological findings in PS was not correlated with the sacroiliac features found on MRI or pelvic CT scan (p=0,59 and p=0,1).Conclusion:In SpA criteria, PS changes were not considered. It can be an additional help in making the diagnosis. Interestingly, pubic symphysis may exist without sacroiliitis.Disclosure of Interests:None declared.
