Background: This is a literature review aiming to provide an update about the recent findings related to the efficacy of middle meningeal artery embolization (MMAE) in the treatment of chronic subdural hematomas (cSDHs), comparison with conventional therapy and deduction of the current recommendations and indications. Methods: The literature is reviewed using a search through the PubMed index using keywords. Studies are then screened, skimmed, and thoroughly read. 32 studies fulfilled the inclusion criteria and are included in the study. Results: Five indications for the application of MMA embolization (MMAE) are deducted from the literature. The usage as a preventive measure after surgical treatment of symptomatic cSDHs in patients with a high risk of recurrence and the usage as a standalone procedure has been the most common reasons for indication of this procedure. Rates of failures for the aforementioned indications have been 6.8% and 3.8%, respectively. Conclusion: The safety of MMAE as a procedure is regarded as a general theme in the literature and can be considered for future applications. Usage of this procedure in clinical trials with more patient segregation and timeframe assessment relative to surgical intervention are recommendations of this literature review.
Musculoskeletal disorders (MSD), notably neck pain, are important occupational health issues in the field of dentistry. Many studies were done worldwide to gather data about neck and back pain. They used different characteristics and risk factors. Other studies aimed to determine only the prevalence of neck and back problems among dentists. We aim to review the literature for research about the optimal factors to be assessed and the proper measures to be installed by dentists to prevent cervical pain and to be taught and shared with dental students. Such an aim requires a thorough review of the current condition. This is a brief review of the literature to shed light on the latest news on this topic. Research using keywords such as dentistry, neck pain, neck pain index, occupational pain, and dental specialties were used to skim the literature for related topics. Publications are considered based on their relevance to the topic. Topics related to other professions and pain induced by illnesses other than occupational factors are not included. The final conclusion shows that no final results were conducted regarding the optimal characteristics that the dentists should be using. Therefore, we recommend a study with an aim to determine the optimal factors to be used by dentists to prevent cervical pain and to be taught to dental students.
BackgroundEarly epidural steroid injections are currently widely used for patients experiencing lumbago. However, there is uncertainty about their efficacy, such as the limitation of continuous drug infusion and the need for well-trained physicians on this technique. The main objective of this study was to evaluate the effectiveness of early epidural steroid injections in treating patients with acute sciatica in the lower back in terms of symptom relief and recurrence rate. MethodsA case series was conducted in Lebanon from 2015 to 2019. We recruited 98 patients suffering from sciatica due to disc disease over three-time intervals: two weeks, one, and three months. The immediate results accounted for the intensity of various symptoms (numerical rating scale (NRS) for pain) and the assessment of patient satisfaction (Macnab criteria). ResultsThe clinical results showed at least a three-point pain relief according to Numerical Rating Scale (NRS) and a good grade according to MacNab (P <0.001), with only 10.4% of the total population having a positive leg raise test post-injection. The maximum benefit was noted after two weeks from the injection with a 5.7 mean change in NRS (p<0.001) with a good/excellent response in MacNab and a 4.9 change with only a good response after one month. This study noticed a rebound phenomenon where around half of the patients needed two steroid injections after three months (39.6 % after three months and 17.9 % after six months). ConclusionEven though current guidelines worldwide may suggest the use of conservative treatment for low back pain with acute sciatica, our study has demonstrated the effectiveness of epidural steroid injections in the Lebanese population with a significant outcome.
In the past three years, Lebanon, a country located in the Middle East, has faced a severe financial crisis. This crisis had many effects on several sectors in Lebanon, including the healthcare sector. The authors expected an increase in the rate of complicated appendicitis after the crisis due to the shortage of medical supplies. The aim of the study was to compare the rate of complicated acute appendicitis before and after the Lebanese crisis. MethodsThe study included two groups of patients with acute appendicitis. The first group included patients admitted in the period between November 2018 and November 2019 (before the crisis). The second group included patients admitted between November 2020 and November 2021 (during the crisis). The data were collected retrospectively and analyzed using SPSS software (version 25.00) (SPSS Inc., Chicago, IL). Ethical approval was obtained and the study was registered at Al Zahraa hospital, University Medical Center in Beirut, Lebanon. ResultsThe study included 49 patients in the first group (before the crisis) and 46 patients in the second group (after the crisis). The percentage of complicated appendicitis has increased from 22.4% before the crisis to 28.3% during the crisis. The study showed a statistically significant difference between the two groups in the white blood cell count (10,831 versus 7180 cu.mm, respectively, p=0.006), the operating time (59.9 versus 79.0 minutes, respectively; p=0.004), the need to obtain an intra-peritoneal swab for bacterial culture (83.7% versus 58.7%, respectively; p=0.007), and the need for intra-abdominal abscess drainage (6.1% versus 28.3%, respectively; p=0.004). There were no significant differences in the demographics, the duration of postoperative antibiotic use, the duration of stay in the hospital, and the postoperative complications in the first month following surgery. ConclusionDue to the decreased financial income, the high cost of medical care during the Lebanese crisis, and the delay of patients' presentation to the hospital, the rate of complicated appendicitis increased during the crisis.
Background and Objectives. In the area of dentistry, musculoskeletal disorders (MSDs), particularly neck discomfort, are significant occupational health hazards. The purpose of this study was to ascertain how neck pain affected the capacity and productivity of dental practices. Additionally, it examined the advantages of preventive measures in lessening pain intensity and rated the degree of dentists’ incapacity. Subjects and Methods. This study used a cross-sectional survey design to examine how neck pain affected dentists’ ability to work and their productivity between July 2022 and November 2022. The study included 342 dentists from all around Lebanon. An online validated survey was designed, and the data collection process was performed via direct calls and emails where the survey link was shared. Data included demographic characteristics, gender, type, and duration of the dental practice, which were presented by the toll of hours of work per week, general health status, exercise habits, and Neck Disability Index (NDI). The weight of the participants was not included in the study. The statistical analysis was performed using IBM SPSS version 25. Results. The majority of participants were between the ages of 25 and 35, and the gender distribution of the demographic distribution was comparable. The prevalence of pain was 86.8% (97/342 dentists). NDI analysis showed that 65.7% had mild disability, 12.8% have a moderate disability, and 1% had severe disability. Bivariate analysis showed that pain was affected by age ( p = 0.013 ), orthodontist practices ( p = 0.031 ), regular exercise ( p < 0.001 ), using vibrating instruments ( p < 0.001 ), cervical flexion for better vision while working ( p < 0.001 ), knowledge, and experience about ergonomic posture ( p < 0.005 ). Multivariate analysis showed four predictors for pain: age ( p = 0.017 ), performing stretching exercises after finishing clinical practice ( p = 0.022 ), orthodontist specialty ( p = 0.029 ), and performing cervical flexion for better vision while working ( p = 0.004 ). Conclusion. This study showed that through the application of some strategies such as stretching, exercising, and being careful in using vibrating instruments, the dentist may be able to relieve the pain.
Background: The B.1.1.7 SARS-CoV-2 variant results in spike gene target failure (SGTF) in reverse transcription-quantitative polymerase chain reaction (RT-PCR) assays. Few studies have been published on the clinical impact of B.1.1.7/SGTF. Aims: To assess the incidence of B.1.1.7/SGTF and its associated clinical characteristics among hospitalized COVID-19 patients. Methods: This observational, single-centre, cohort study was conducted between December 2020 and February 2021 and included 387 hospitalized COVID-19 patients. The Kaplan–Meier method was used for survival analysis, and logistic regression to identify risk factors associated with B.1.1.7/SGTF. Results: By February 2021, B.1.1.7/SGTF (88%) dominated the SARS-CoV-2 PCR results in a Lebanese hospital. Of the 387 eligible COVID-19 patients confirmed by SARS-CoV-2 RT-PCR, 154 (40%) were non-SGTF and 233 (60%) were B.1.1.1.7/SGTF; this was associated with a higher mortality rate among female patients [22/51 (43%) vs 7/37 (19%); P = 0.0170]. Among patients in the B.1.1.7/SGTF group, most were aged ≥ 65 years [162/233 (70%) vs 74/154 (48%); P < 0.0001]. Independent predictors of B.1.1.7/SGTF infection were hypertension (OR = 0.415; CI: 0.242–0.711; P = 0.0010), age ≥ 65 years (OR = 0.379; CI: 0.231–0.622; P < 0.0001), smoking (OR = 1.698; CI: 1.023–2.819; P = 0.0410), and cardiovascular disease (OR = 3.812; CI: 2.215–6.389; P < 0.0001). Only non-SGTF patients experienced multi-organ failure [5/154 (4%) vs 0/233 (0%); P = 0.0096]. Conclusion: There was a clear difference between the clinical features associated with B.1.1.7/SGTF and non-SGTF lineages. Tracking viral evolution and its clinical impact is crucial for proper understanding and management of the COVID-19 pandemic.
Gliomas are among the most common primary tumors of the brain. Discrimination among tumors of more than one focus has segregated the latter into two groups: multifocal gliomas and multicentric gliomas (MCGs). In this case series, outcomes among three patients are described and discussed in light of the findings present in the literature. Ideally, it is crucial to consider genetic testing for categorizing each tumor. This can help determine the original genetic mutations of MCGs and allow to establish necessary screening testing for early detection. We present the cases of three patients diagnosed with cranial gliomas. The first case showed two synchronous gliomas at different loci in the right hemisphere. The second patient showed synchronous lesions on cranial magnetic resonance imaging in each hemisphere. The third case was of a patient with metachronous lesions appearing at different times with similar radiological findings at different loci of the same hemisphere. Discrimination among multifocal and multicentric gliomas requires genetic workup because radiological and temporal findings may fail to allow adequate discrimination.
