The crescent sign—a predictor of hip instability in magnetic resonance arthrography

ABSTRACT Currently, much is debated on the optimal treatment of borderline hips, being in the continuum between stable and unstable hips. The diagnosis of stability is often difficult but is a prerequisite for further treatment. Analysis includes a variety of radiographic parameters. We observed that unstable hips often had a crescent-like gadolinium collection in the postero-inferior joint space. We therefore questioned if the ‘crescent sign’ could be an indicator for hip instability? A retrospective comparative study was conducted including 56 hips in the instability group (treated with PAO) and 70 hips with femoroacetabular impingement (FAI) as control group. Based on standard radiographic parameters and magnetic resonance imaging (MRI), the association between hip instability and the ‘crescent sign’ was analyzed. For univariate group comparisons, the non-parametric Wilcoxon two sample test was used. Association between discrete variables was examined by means of chi-square tests. To examine predictive variables, logistic regression models were carried out. Most hips with a crescent sign belong to the instability group. A crescent sign has a sensitivity of 73.3% and specificity of 93% for instability. Based on our results, the crescent sign is a factor that is more prevalent in unstable hips. However, its absence does not exclude instability of the hip. If present, the specificity speaks strongly in favor for instability of the hip.

AbstractTo evaluate the acoustic emissions (AE) and kinematic instability (KI) of the osteoarthritic (OA) knee joints, and to compare these signals to radiographic findings. Sixty-six female and 43 male participants aged 44–67 were recruited. On radiography, joint-space narrowing, osteophytes and Kellgren–Lawrence (KL) grade were evaluated. Based on radiography, 54 subjects (the study group) were diagnosed with radiographic OA (KL-grade ≥ 2) while the remaining 55 subjects (KL-grade < 2) formed the control group. AE and KI were recorded with a custom-made prototype and compared with radiographic findings using area-under-curve (AUC) and independent T-test. Predictive logistic regression models were constructed using leave-one-out cross validation. In females, the parameters reflecting consistency of the AE patterns during specific tasks, KI, BMI and age had a significant statistical difference between the OA and control groups (p = 0.001–0.036). The selected AE signals, KI, age and BMI were used to construct a predictive model for radiographic OA with AUC of 90.3% (95% CI 83.5–97.2%) which showed a statistical improvement of the reference model based on age and BMI, with AUC of 84.2% (95% CI 74.8–93.6%). In males, the predictive model failed to improve the reference model. AE and KI provide complementary information to detect radiographic knee OA in females.

Abstract Introduction Over 25% of burn-injured patients at our institution never attended a follow-up appointment. A quality-improvement discharge survey (QIS) identified potential barriers to follow-up as distance from the clinic, transportation, and time off work. This study compares follow-up rates before and after the QIS was administered and correlates them with patients’ self-identified barriers. Methods Following IRB approval, a retrospective chart review was conducted using electronic medical records of adult burn-center admits who responded to the QIS and were discharged between September 2019 and July 2020. Controls were burn-center admits discharged from 2016–2018, prior to the survey period. Exclusions included patients with non-burn injuries, and those who died in the hospital were transferred to another hospital, did not require follow-up, or followed up elsewhere. Data analysis was conducted using chi-square, t-test, and logistic regression models. Results The post-survey group includes 272 patients (mean age 47 ± 16.8, 201 males (73.6%), mean burn size (TBSA) of 9.3% ± 9.6%). The pre-survey control group includes 878 patients (mean age 45.1 ± 16.8 years, 646 males (73.6%), mean burn size (TBSA) 10.16 ± 11.7%). Compared to the pre-survey group, post-survey patients had a lower frequency of missed appointments (MA) (47.3% post vs. 56% pre), but worse overall follow-up rates (63.7% post vs. 74.5% pre). Per multivariate analysis, different factors were associated with follow-up and MA in the two groups (Table 1). Rates of follow-up and MA were not significantly different before and after the onset of the Covid-19 pandemic. Conclusions Patients who were surveyed to identify barriers to follow-up had fewer missed appointments but worse overall follow-up rates. Patients fail to follow up due to homelessness, substance dependence, and distance to the hospital. These findings are consistent with patients’ self-identified barriers to follow-up in a QI survey.

Iron supplementation is a government program to overcome anemia among expectant mothers, and some of the expectant mothers still do not obediently consume iron tablets. Therefore, to increase the obedience of the expectant mothers on consuming the iron tablets, SMS reminder is the appropriate method needed. This research aims to identify the effectiveness of SMS reminder to the obedience of iron tablets consumption among expectant mothers at UPT Puskesmas Cibuntu , Bandung. The research employed quasi-experimental design with posttest-only control group design using purposive sampling technique. The research was held on April–May 2014 at UPT Puskesmas Cibuntu, Bandung. Forty expectant mothers consuming iron tablets disobediently divided into 20 intervention groups and 20 control groups were taken as the samples. Questionnaire in form of self report was used to obtain data. In addition, descriptive analysis and chi square test were applied to analyze the data. The result of the research showed that 17 persons (85%) of intervention groups were mostly obedient, and 16 persons (80%) of control groups were mostly disobedient. From the analysis using chi square, it was found the difference of the obedience of iron tablets consumption after SMS reminder (p=0.00) had been delivered with significant level <0.05. Based on the result of this research, SMS reminder had an effective impact toward the obedience of iron tablets consumption among the expectant mothers. The result will be a good consideration for Puskesmas to cooperate with provider or proposed some funds to Dinas Kesehatan to activate SMS reminder.Key words:Expectant mothers, obedience, SMS reminder, iron tablets

Background: There are limited scientific investigations on cognitive remediation in elderly patients with schizophrenia. The present study was aimed to examine the efficacy of cognitive remediation therapy on social skills in institutionalized elderly patients with schizophrenia. Methods: The study employed a randomized clinical trial. A total of 60 institutionalized elderly patients with schizophrenia from Razi Psychiatric Hospital, Tehran were selected and randomly allocated into two equal groups (control and intervention). The intervention group attended to cognitive remediation therapy for 8 weeks. The Evaluation of Living Skills Scale for psychiatric patients was used for data collection. The Chi Square, independent and paired t-tests using SPSS, version 22, were employed to analyze the data. Results: The mean age of 60 elderly patients participated in the study was 65.25 ± 4.19 years. No significant differences were found between two groups at baseline. However, independent t-tests showed significant differences between the intervention and the control group in social skills after implementation of intervention. Additionally, the results of paired t-tests revealed significant improvements in intervention group on communication skills (t=5.50, p<0.001), behavioral problems with others (t=5.44, p<0.001), and self-care (t=4.70, p<0.001). No significant differences were observed from pretest to post test in control group. Conclusion: The results of the present study may support the efficacy of cognitive remediation therapy on social skills of elderly patients with schizophrenia.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract α-tocopherol is known to be a powerful antioxidant, in this regard, it was added to bovine oocyte in vitro maturation media to evaluate its effect on oocyte maturation. Oocytes (n = 624) aspirated from ovaries of slaughtered cows were classified by quality and divided in four categories according to cytoplasm appearance and cumulus cells layers. Oocytes were washed in TCM-199 supplemented with fetal bovine serum (FBS) and FSH, then distributed in maturation media (TCM-199 supplemented with FBS, FSH and gentamicin). Three experimental groups of α-tocopherol (50, 100 and 200 mM) and a control group without α-tocopherol were used. Maturation was carried 22 h at 38.5°C in a 5% CO2 atmosphere. Oocytes were examined to determine cumulus expansion as categorical data (expansion or no expansion), as well as cumulus expansion Index (CEI). For CEI determination oocytes were graded 0 to 4, being 0 those with null expansion and 4 those with a noticeable cell expansion, then the number of oocytes were multiplied by the grade given and a sum of the totals was obtained, the new total was divided by the total of oocytes in the group and the result obtained corresponded to the CEI of the group. Results were analyzed with Chi Square test (for maturation rates) and an ANOVA (for the CEI) using the SAS system, data are presented as mean ± standard error. There was no statistical difference between control and α-tocopherol groups (P >0.05). Numerically, the control group showed a higher maturation rate (100%) and obtained a higher CEI (2.44±0.20), followed by the 50 mM group (98.16%; 2.39±0.13), the groups 200 mM (97.40%; 2.00±0.14) and 100 mM (96.25%; 2.06±0.24) were the lowest. The addition of the minimum concentration (50 mM) of α-tocopherol to the maturation media could improve maturation rates without exposing oocytes to toxic effects.
