Abstract Background To describe the epidemiology, characteristics, risk factors, and outcomes of post-traumatic endophthalmitis. Main body Medical records of consecutive open globe injury patients admitted and primarily treated between January 2006 and December 2016 were retrospectively reviewed. Patients were defined as having or not having associated endophthalmitis. Data of demographics, injury characteristics, clinical presentations, and visual outcomes were collected. The potential risks and significant factors for visual outcomes of post-traumatic endophthalmitis were determined. There were 591 patients included in this study. Among these, 118 patients were clinically diagnosed as having accompanied endophthalmitis. Higher proportions of intraocular foreign body (IOFB) (55.1% vs. 27.3%) and injury related to high-velocity objects (55.9% vs. 32.6%) were noted in patients with endophthalmitis compared to patients without endophthalmitis. Anterior wound location (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.1 to 3.7; P = 0.020), presence of IOFB (OR, 1.9; 95% CI 1.2 to 3.0; P = 0.005), and delayed presentation of > 24 h (OR, 3.9; 95% CI 2.3 to 6.4; P < 0.001) were significant risk factors for associated endophthalmitis. Final visual acuity (VA) of the overall population improved significantly from 2.4 (0.6) logMAR to 1.4 (0.1) logMAR, P < 0.001, however, patients in the endophthalmitis group achieved a worse final VA than the non-endophthalmitis group (66.1% vs. 43.5%, P < 0.001). Conclusion High proportions of post-traumatic endophthalmitis patients had subsequent poor visual outcomes. Therefore, safety and protective measurements, especially when performing activities related to high-velocity objects, and the institution of prophylactic antibiotics in high-risk groups should be promptly considered to reduce the incidence.

Abstract Background: Open globe injury (OGI) is one of the most devastating form of ocular trauma. The aim of the study is to identify the epidemiology and predict visual outcomes in traumatic open globe injuries using ocular trauma score (OTS) and correlate with final visual acuity (VA) at 3 months. Methods: Patients older than 5 years, presenting to B.P. Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) from March 2016- March 2017 with OGI that met inclusion criteria were evaluated. Patient profile, nature and cause of injury, and time to presentation were recorded. Patients were managed accordingly and followed up to 3 months. An OTS score for each patient was calculated and raw scores were categorized accordingly. The VA after 3 months were compared to the predicted OTS values. Results: Seventy-three eyes of 72 patients were examined. 76% were male, and the mean age was 26.17 years (median, 23.5 years). The mean time from injury to presentation was <6 hours (30 patients, 41%). Thirty-seven eyes (51%) had zone I trauma, followed by twenty eyes (27%) with zone II, and sixteen eyes (22%) with zone III trauma. Sixty-five patients (90%) were managed surgically, and fifty (68%) received intravitreal antibiotics with steroid. When compared, the projected VA as per OTS were able to predict actual final visual outcomes in 60% of the eyes with OGI of various zones (p<0.05). Conclusion: OTS can be an accurate predictive tool for final visual acuity even with a short follow up period of 3 months; with poor presenting visual acuity, delayed presentation, posterior zones of injury, need for intravitreal injections, endophthalmitis, and globe rupture associated with poorer prognosis.

Construction projects are subjected to a variety of risks eventually affecting the overall duration and green building projects are no exception. Use of risk assessment means in such projects is also critical to complete them within aimed schedule. In this study, risks that have potential schedule impacts in certified green building projects are identified and their impact and likelihood of occurrence values are researched. For this purpose, a survey is administered to construction professionals with green building experience. Based on the responses, risks are plotted to draw their potential impact on schedule/likelihood of occurrence in a graph to identify the most significant risk factors. This tool may help the practitioners to identify and prioritize potential risks and allocate resources in projects accordingly to prevent or minimize their possible impacts.

Purpose To determine the risk factors for post-traumatic endophthalmitis in patients with positive intraocular culture. Methods An institutional-based prospective nonrandomized interventional study of patients older than 15 years who presented for primary repair of open globe injury between June 2003 and April 2005 was undertaken. The main outcomes measured were initial and final visual acuity, type of injury, presence of uveal and vitreous prolapse, time interval between injury and primary repair of the globe, length of wound, location of wound, and virulence of organism. Statistical analysis tests used were Student t-test, Fisher exact test, and chi-square test. Results Fifty patients were included in the study. They were divided into two groups: Group 1 (n=19) patients, who developed clinically significant endophthalmitis; and Group 2 (n=31) patients, who did not develop clinically significant endophthalmitis. Delay in primary repair more than 36 hours (p=0.042), length of wound more than 8 mm (p=0.050), and isolation of organisms like fungus (p=0.006, OR=14), Bacillus cereus (p=0.01, OR=11.25), and Pseudomonas aeruginosa (p=0.05–0.10, OR=11.3) significantly increased the risk of endophthalmitis. Mean initial and final visual acuity was better in Group 2 but was not statistically significant (p=0.21). Conclusions Final visual outcome in the presence of positive intraocular culture is poor. Isolation of virulent organisms, longer length of laceration, and delayed primary repair of open globe injuries have high risk of developing endophthalmitis. Prophylactic intraocular antibiotics should be considered in cases with longer length of wound and delayed primary closure.

Abstract This study was performed to identify risk factors for pelvic nodal failure (PNF) after definitive concurrent chemo-radiotherapy (CCRT) in patients with metastatic pelvic lymph nodes (mPLNs) from squamous cell carcinoma (SCC) of the cervix. We retrospectively reviewed data on 80 patients who received definitive CCRT between 2005 and 2014 at our hospital. All patients underwent brachytherapy and whole-pelvic radiotherapy (WPRT) without nodal boost. mPLNs was diagnosed by magnetic resonance imaging and positron emission tomography. The rate of PNF and factors affecting PNF were analysed. A total of 156 mPLNs were found. The median number of mPLNs was 2 per patient (range 1–6); the median short diameter was 1.7 cm (range 1.0–4.2 cm). After a median follow-up of 64 months, 10 (6.4%) mPLNs failed in 13 (16.3%) patients. The 5-year PNF-free survival (PNFFS), disease-free survival and overall survival rates were 83.4, 62.7 and 74.7%, respectively. The mPLN size was not associated with the risk of PNF. However, pre-radiotherapy SCC antigen (SCC-Ag) &gt;6.8 ng/mL and number of mPLNs &gt;2 were significant risk factors for PNF. Using the two risk factors, we categorized the patients into three risk groups. The 5-year PNFFS rates in patients with 0, 1 and 2 risk factors were 100.0, 78.3 and 44.4%, respectively (P &lt; 0.01). SCC-Ag level and number of mPLNs were significant factors for PNF. Patients with both risk factors developed frequent PNF after WPRT without nodal boost. The two risk factors can be a guide in deciding whether to administer nodal boost radiotherapy.

Annotation. Goal – to identify and assess the most significant risk factors for the development of simple non-atypical endometrial hyperplasia (SNAEH) and complex non-atypical endometrial hyperplasia (CNAEH) in women. Retrospective analysis of anamnestic data of 58 case histories of patients with SNAEH, 35 case histories of patients with CNAEH and data of 30 women of the control group, which allowed to identify risk factors for hyperproliferative processes of the endometrium (HPE) for research, the statistical significance of which was further assessed by calculating odds ratio (OR). The main feature associated with the risk of SNAEH is heredity – OR = 49.73 (95% CI 2.90–852.32). Significantly increases the risk of developing SNAEH in the presence of thyroid gland lesion (TGL) – OR = 34.97 (95% CI 2.03–601.20). The third in the hierarchical sequence is the polycystic ovary syndrome factor; OR = 25.72 (95% CI 1.488–444.59). Heredity occupies the top of the hierarchical structure in the group of patients with CNAEH. OR is 80.67 (95% CI 4.56–1424.76). A high probability of developing CNAEH is also observed for women over the age of 50 (OR = 32.44 (95% CI 1.82–576.56). In third place – the presence of TGL, which significantly increases the risk of developing CNAEH; OR = 28.63 (95% CI 1.60–510.56) Identification of statistically significant risk factors for the development of HPE will help to identify risk groups among the population, to carry out preventive measures among them (lifestyle adjustments, treatment of concomitant diseases) and decrease the incidence of the HPE.

The primary aim of this study was to determine whether psychosocial factors, such as post-traumatic stress disorder (PTSD) and anxiety, are independently associated with the development of central serous chorioretinopathy (CSCR), a predominantly male eye disorder. A secondary aim was to verify previously determined risk factors in a veteran population. All CSCR subjects seen in one year at a veteran eye clinic were included. Chart review was performed to identify general health information as well as eye history. Univariate and multivariate analysis was performed to identify factors that were independently associated with the development of CSCR. Fifty-one cases of CSCR were identified and an additional 51 age-matched controls with healthy eyes were used for analysis. Multivariate analysis revealed that history of PTSD was strongly associated with the development of CSCR (OR = 9.43, p = .002), even more so than previously reported risk factors. Anxiety was significant at the univariate level (OR = 6.48, p = .001) but lost significance at the multivariate level. At the multivariate level, several existing risk factors were confirmed including sleep apnea (OR = 5.76, p = .004), heart disease (OR = 7.06, p = .004), smoking (OR = 5.52, p = .003) and steroid use (OR = 4.55, p = .005). PTSD was strongly associated with the development of CSCR in the veteran population studied and may represent an important modifiable risk factor.

Abstract Post-traumatic hydrocephalus (PTH) following traumatic brain injury (TBI) may develop within or beyond the acute phase of recovery. Recognition and subsequent treatment of this condition leads to improved neurologic outcomes. In this scoping review, we identify statistically significant demographic, clinical, radiographic, and surgical risk factors as well as a predictive time frame for the onset of PTH in order to facilitate timely diagnosis. Two researchers independently performed a scoping review of the PubMed and Cochrane databases for articles relevant to risk factors for PTH. Articles that met inclusion and exclusion criteria underwent qualitative analysis. Twenty-seven articles were reviewed for statistically significant risk factors and a proposed time frame for the onset of PTH. Variables that could serve as proxies for severe brain injuries were identified as risk factors. The most commonly identified risk factors included either very young or old age, intracranial hemorrhage including intraventricular hemorrhage, hygroma, and need for decompressive craniectomy. Although the timeframe for diagnosis of PTH varied widely from within one week to 31.5 months after injury, the first 50 days were more likely. Established risk factors and timeframe for PTH development may assist clinicians in the early diagnosis of PTH after TBI. Increased consistency in diagnostic criterion and reporting of PTH may improve recognition with early treatment of this condition in order to improve outcomes.

Abstract Background The aim of our study is to determine the incidence, timing, and risk factors for cerebral vasculopathy after cranial proton and photon radiation for pediatric brain tumors. Methods We performed a single-institution retrospective review of a cohort of children treated with proton radiation for brain tumors. MRA and/or MRI were reviewed for evidence of cerebral vascular stenosis and infarcts. Twenty-one similar studies (17 photon, 4 proton) were identified by systematic literature review. Results For 81 patients with median follow-up of 3 years, the rates of overall and severe vasculopathy were 9.9% and 6.2% respectively, occurring a median of 2 years post radiation. Dose to optic chiasm greater than 45 Gy and suprasellar location were significant risk factors. Results were consistent with 4 prior proton studies (752 patients) that reported incidence of 5% to 6.7%, 1.5 to 3 years post radiation. With significantly longer follow-up (3.7-19 years), 9 studies (1108 patients) with traditional photon radiation reported a higher rate (6.3%-20%) and longer time to vasculopathy (2-28 years). Significant risk factors were neurofibromatosis type 1 (NF-1; rate 7.6%-60%) and suprasellar tumors (9%-20%). In 10 studies with photon radiation (1708 patients), the stroke rate was 2% to 18.8% (2.3-24 years post radiation). Conclusions Childhood brain tumor survivors need screening for vasculopathy after cranial radiation, especially with higher dose to optic chiasm, NF-1, and suprasellar tumors. Prospective studies are needed to identify risk groups, and ideal modality and timing, for screening of this toxicity.
