The aim of this study is to compare the diagnostic accuracy of ultrasonography (US) with magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of choledocholithiasis in context of laboratory blood test values.This retrospective study included patients who underwent both MRCP and US as part of their choledocholithiasis workup. MRCP findings, reviewed by two board-certified radiologists, laboratory findings, and US reports were collected.Our study included 243 patients. On US examination 74 cases were found dilated (30.5%), while 94 cases showed dilation (38.7%) by MRCP. The overall accuracy of US was 76.1%, where 185 patients had similar MRCP and US findings, 7.8% had false positive ultrasound, and 16% had false negative ultrasound finding. The accuracy of ultrasound was significantly higher in males (p = .013). In addition, a significant difference in duct dilatation as found by ultrasound and accuracy of diagnosis (p = .01).Although US has a relatively low accuracy, its properties of being cost-effective and non-invasive make it an ideal first step in the diagnosis of choledocholithiasis. If a patient has elevated liver enzymes or a high risk of choledocholithiasis, we recommend that MRCP be performed even no dilation was seen on US.

Objectives In developing countries, the pneumococcal conjugate vaccine (PCV) has not been incorporated into the national immunization schedule, and the vaccination rate is low. This study aimed to examine parental knowledge, attitudes, and barriers to children receiving the PCV in Jordan. Methods This was a questionnaire-based cross-sectional study. The online survey was written in Arabic and consisted of three main sections. The questionnaire was distributed via social media platforms, such as Facebook, Twitter, and WhatsApp. Results In total, 720 responses were analyzed. Only 149 (20.7%) of the parents’ children were vaccinated with the PCV. However, almost half 356 (49.4%) of the respondents were willing to vaccinate their children. Most (563, 78.1%) parents stated that the vaccine would protect their children from pneumococcal disease. More than two thirds (516, 71.6%) of them strongly agreed or agreed that the cost of the PCV is high. Parents who had vaccinated their children had a higher monthly income than parents who had not vaccinated their children. Conclusions This study shows a lack of knowledge regarding pneumococcal infection and the PCV among Jordanian parents. This is the main barrier to vaccinating children. Therefore, improving parental knowledge would increase the rate of vaccination among Jordanian children.

Introduction Neck-shaft angle (NSA) is of paramount importance to orthopedic surgeons due to its implications for various pathologies of the hip and femur. The primary aim of the study was to establish if NSA measurement may be affected by imaging position (standing and supine) and provide evidence regarding whether the contralateral NSA can be used as a template. The secondary aim was to determine a reference value and precisely understand the effects of sex on NSA measurement. Materials and methods We measured bilateral NSA in a retrospective study of 200 standing and 200 supine anteroposterior pelvis radiographs that met the inclusion criteria, while paying special attention to bilateral hip symmetry. The overall inter-rater reliability was 0.688 (CI 0.128–0.851). Matching was performed according to sex (exact matching) and age. Paired t-test, Pearson correlation coefficient, and independent sample t-test were used (p Results A total of 400 pairs of femoral necks were reviewed, comprising of 200 males and 200 females. In the upright radiograph, the overall mean NSA was 131.21° ± 4.72°. There was no significant difference between right and left femur NSA among the patients (p = 0.95). On both sides, male NSA was higher than female NSA (p p p = 0.85). Conclusion Our findings indicated no significant variability in upright radiographs between the right and left NSA. In contrast, significant asymmetry between the right and left NSA was found in the supine radiographs. However, this study does not provide definitive clinical evidence, and further clinical-oriented research is required. Level of evidence Level III; retrospective comparative study.

Glyphosate-based herbicides are the most used herbicides in the world. Despite being widely used, a dispute exists whether glyphosate-based herbicides have a negative effect on human health, particularly genotoxic effects. Therefore, the aim of this study was to investigate glyphosate genotoxicity on cultured human lymphocytes. Cultured human lymphocytes were treated with different concentrations of glyphosate (20, 40, and 200 µmol/L). Four toxicity measures were examined: frequency of chromosomal aberrations (CAs), frequency of sister-chromatid exchange (SCE), production of 8-OHdG, and cell kinetics analysis. The results show that glyphosate induced significant ( P < 0.05) increases in the levels of SCE at the highest used concentration (200 μmol/L). However, no significant elevation in SCE levels was observed at the lower examined concentrations (20 and 40 μmol/L). No significant changes in CA were detected at all examined concentrations ( P = 0.86). Also, glyphosate did not induce changes to the normal level of 8-OHdG at all examined concentrations ( P = 0.98). Last, no significant changes in either mitotic index or proliferative index were observed at any examined concentrations ( P > 0.05). The results collectively indicate a lack of genotoxicity and cytotoxicity of glyphosate in cultured human lymphocytes when dealing with environmentally relevant concentrations (20 and 40 μmol/L). However, being exposed to higher concentrations (200 μmol/L) led to slightly higher level of SCE. Therefore, we recommend cautionary measures when dealing with glyphosate-based herbicides for individuals, such as farmers, who may be extensively exposed to high concentrations of these herbicides.

Noninvasive follicular neoplasm with papillary-like nuclear features (NIFTP) is the term to describe what was previously known as encapsulated follicular variant of papillary thyroid carcinoma. This new paradigm shift was agreed upon by experts in the field. The objective of this study is to evaluate cases previously diagnosed as follicular adenomas, follicular variant of papillary thyroid carcinoma and hyperplastic nodules to be reclassified as NIFTP according to the new criteria. Furthermore, the clinical follow-up of these NIFTP cases is evaluated.This retrospective study reviewed potential NIFTP cases over the last 13 years, at Jordan University Hospital.A total of 811 thyroid surgery reports were identified and revised to identify the potential NIFTP cases. The review yielded 173 cases identified as potential NIFTP cases. Further pathological slide review resulted in a revised diagnosis of 32 cases of NIFTP according to the new criteria. The NIFTP cases comprised 4% of the total number of thyroidectomy cases and 16.1% of the total pool of previously diagnosed papillary thyroid carcinoma cases at our institution. While 111 cases retained their original diagnosis. Follow-up showed that all patients are alive and well with no evidence of disease.Patients with NIFTP are not uncommon and the diagnosis is made only after a thorough evaluation of excision. Therefore, initial conservative management of solitary thyroid nodules suspicious for NIFTP in the form of lobectomy is recommended to avoid unnecessary total thyroidectomies. Our follow-up of NIFTP cases is similar to all previous reports.
