Introduction: Intertrochanteric fractures occur in about 50% of all hip fracture events, with a mortality rate within 1 year after fracture reaching 15 to 20%. The most common treatment nowadays is either the bipolar hemiarthroplasty procedure or proximal femoral nail anti-rotation (PFNA), although there is still no consensus regarding which is better from the two, especially on patient mortality.Method: This study was an observational study using a retrospective cohort design. A total of 102 study subjects who met the inclusion requirements were grouped into 2 groups, one with bipolar hemiarthroplasty fixation treatment and another with PFNA fixation treatment. Mortality rate was recorded by survey 2 years after surgery.Result: Chi-square test showed that 2-year mortality rate after intertrochanteric fracture treated with bipolar hemiarthroplasty (21.4%) was significantly higher than the PFNA group (10.3%) (p=0.028). Bipolar hemiarthroplasty group also had longer length of stay (LoS) (50%) than the PFNA group (32.4%), albeit statistically insignificant (p=0.13). There was no significant difference between the 2-year mortality rate and LoS (p=0.976).Conclusion: Patients with intertrochanteric fractures who underwent bipolar hemiarthroplasty have significantly higher 2-year mortality rate than similar patients underwent fixation with PFNA, while they did not experience higher LoS than the PFNA group. Future prospective, multi-center study with larger sample size will be likely to validate similar fixation choice needed to decrease the mortality rate in intertrochanteric fractures.

Abstract Background: Although proximal femoral nail anti-rotation (PFNA) and bipolar hemiarthroplasty (BHA) are selected by most of the orthopaedic surgeons for elderly intertrochanteric fractures (ITFs) patients, there is still no consensus on the superiority of PFNA and BPH for ITFs in the elderly. The study aims to compare the curative effects of proximal femoral nail anti-rotation (PFNA) and cementless bipolar hemiarthroplasty (BHA) on ITFs in the elderly. Methods: From January 2012 to December 2016, a total of 62 patients participated in the study: BHA (Group B, n=30), PFNA (Group P, n=32). The fractures were classified according to Evans-Jensen. Hospitalization time, operation time, bleeding loss, Harris scores and postoperative complications were compared between the two groups. Results: The operation time was (125.76 ± 33.49) min and (94.38 ± 20.94) min in PFNA group and BHA group (P < 0.05); bleeding loss was (153.33 ± 59.96) mL and (335.31 ± 90.87) mL(P < 0.05); hospitalization time was (17.13 ± 2.92) days and (16.63 ± 3.64) days (P > 0.05); and the Harris scores were (73.20 ± 6.56) points and (68.91 ± 8.15) points (P < 0.05). There was no significant difference in postoperative complications between the two groups (P > 0.05). Conclusion: Both PFNA and BHA are safe and effective treatments for femoral intertrochanteric fractures in elderly patients. Nonetheless, BHA can be considered for those with the poor bone condition and short life expectancy.

Abstract Background Intertrochanteric fracture is associated with severe morbidity and mortality. The results of postoperative implant failure are catastrophic. The aim of this study was to determine risk factors for implant failure in intertrochanteric fractures treated with proximal femoral nail anti-rotation (PFNA–II) through the assessment of early therapeutic effects. Methods A single-center retrospective study was conducted on a continuous series of 123 intertrochanteric fracture patients treated with PFNA-II between Dec 2018 and Oct 2019. Perioperative medical and imaging data were collected. The patients were divided into two groups according to whether implant failure of not. The differences in reduction quality, nail length and tip apex distance (TAD) were analyzed to determine the risk factors of implant failure. Results A total of 80 patients were enrolled, with an average age of 80.2 years old. There were 6 patients with implant failure. There was no significant difference in demographic index between the two groups. The reduction quality of failure group was good, accept and poor with each 2 patients, and that of the non-failure group was 35, 35 and 4 patients respectively. The difference of reduction quality between the two groups was statistically significant. The risk of postoperative implant failure in patients with poor reduction quality was 8.75 times that of patients with good and acceptable reduction from the Logistic regression analysis(OR = 8.75,95%CI 1.215–62.99). The differences in nail length, ASA and bone quality were not statistically significant. Conclusion Reduction quality is a risk factor of implant failure in intertrochanteric fractures treated with PFNA-II. Even if the medial femoral cortex is anatomically reduced, there will be a triangular void area between the nail and the medial femur, which are prone to coxa vara and implant failure. Therefore, good reduction is the key to treat intertrochanteric fracture.

The Mean

Background: Intertrochanteric femoral fractures are one of the most common types of bone fractures that are usually caused by severe direct or indirect force. It has also been estimated that nearly 50% of all the fractures are intertrochanteric fractures and the remaining are unstable fractures. Also, it has been found that the mortality related to hip fractures is as high as 15-20%. With an increase in the life expectancy of people, there has been a substantial increase in the number of patients with postmenopausal or senile osteoporosis. Aim: To compare Proximal femoral nail anti-rotation with cementless bipolar hemiarthroplasty for unstable femoral intertrochanteric fracture Methods: It was a retrospective study carried out at the Government Medical College, Baramati for a period of 1 year. One hundred patients were included for the scope of the study. Out of which 50 patients belonged to the PFNA group, and 50 patients belonged to the CPH group. Results: The number of patients in the PFNA group was 50 and that in the CPH group was 50. Both groups show male preponderance. The mean age among both the groups was almost the same, and there was no statistically significant difference among the two groups regarding the mean age. The mean operation time for PFNA was 54.15±16.1 mins, and that of the CPH group was 76.69±15.89 mins. The mean bleeding time for PFNA was 133.12±33.16 ml, and that of the CPH group was 289.25±44.01 ml. There was no statistically significant difference among the ASAA grade scores of the two groups. There was no statistically significant difference among the Evans-Jensen classification of the two groups. The mean length of hospital stay for PFNA group was 7.89±2.0 days, and the mean hospital stay for CPH group was 6.54±1.9 days. Conclusion: The current study depicted that CPH and PFNA are both safe and effective methods of treating elderly patients suffering from intertrochanteric fractures. However, it was found in the current study that CPH was found to have more mean operative time and increased blood loss. Still, the recovery and hospitalization time was almost similar in both the groups. Both the groups had almost similar ASA and Evans Jensen scores that made both the techniques equally safe

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Abstract Background To analyze whether corneal refractive surgery (CRS) is associated with the distribution of different accommodative dysfunctions (ADs) and binocular dysfunctions (BDs) in civilian pilots. A further aim was to analyze the percentages and visual symptoms associated with ADs and/or BDs in this population. Methods One hundred and eight civilian pilots who underwent CRS from January 2001 to July 2012 (age: 30.33 ± 4.60 years) were enrolled, the mean preoperative SE was − 1.51 ± 1.15 D (range: − 1.00- − 5.00 D). Ninety-nine emmetropic civilian pilots (age: 29.64 ± 3.77 years) who were age- and sex-matched to the CRS group were also enrolled. Refractive status, accommodative and binocular tests of each subject were performed. Visually related symptoms were quantified using the 19-item College of Optometrists in Vision Development Quality of Life (COVD-QOL) questionnaire. The 19 items were summed to obtain visual symptom scores that might indicate visual dysfunctions. The chi-square test was used to analyze differences in percentages of ADs and/or BDs between the CRS and emmetropic groups. The Mann-Whitney U test was used to compare visual symptom scores between pilots with ADs and/or BDs and pilots with normal binocular vision. Results No significant difference was observed between the CRS and emmetropic groups in the overall prevalence of ADs and BDs (15.7% and 15.2% in the CRS and emmetropic groups, respectively; P = 0.185). ADs were present in 4.63% and 3.03% of the CRS and emmetropic group, respectively. BDs were observed in 11.1% and 12.1% of the CRS and emmetropic group, respectively, yielding no significant differences between the groups in the prevalence of ADs or BDs (AD: P = 0.094; BD: P = 0.105). Pilots with ADs and/or BDs had significantly more visual symptoms than pilots with normal binocular vision (p < 0.001). Conclusions CRS for civilian pilots with low-moderate myopia might not impact binocular functions. ADs and/or BDs commonly occur in both emmetropia pilots and pilots who undergo CRS, and pilots with ADs and/or BDs are associated with increased symptoms. This study confirms the importance of a full assessment of binocular visual functions in detecting and remedying these dysfunctions in this specific population.

Propolis is proposed to possess antibacterial and anti-inflammatory properties, which can be used in endodontic applications. However, evidence on its efficacy in comparison to chlorhexidine against Enterococcus faecalis (E. faecalis) is controversial. The aim of the current study was to compare the antibacterial efficacy of Propolis and chlorhexidine as an intracanal medicament against E. faecalis in extracted human permanent teeth. The focused question was, “Does Propolis show better antibacterial efficacy than Chlorhexidine (CHX) as an intracanal medicament against E. faecalis in extracted human permanent teeth?”. Databases including PubMed/Medline, Scopus, EMBASE, ISI-Web of Science were searched from 1990 to August 2020 using different combinations of the following keywords: “Propolis”, “Intracanal medicament”, “E. faecalis”, “Antibacterial activity” and “Chlorhexidine”. Ten studies fulfilling inclusion criteria were considered for qualitative analysis, followed by quantitative analysis of eight studies. Heterogeneity was calculated for colony forming units (CFU) of E. Faecalis using the Chi-square test and I2 statistics. Forest plots were computed reporting standard mean difference (SMD) of outcomes and 95% confidence intervals. The overall mean difference for CFU of E. faecalis showed a statistically significant difference between the antibacterial efficacy of Propolis and CHX (SMD = 3.20 [1.70, 4.69] Z = 4.20; p < 0.001). CHX showed superior antibacterial efficacy against E. faecalis compared to Propolis.
