Imposter syndrome (IS) and low self-esteem (SE) are common issues affecting medical students that can impact their well-being and development. This study aimed to assess the prevalence and factors associated with IS and SE among medical students at Jazan University, Saudi Arabia. In this cross-sectional study, 523 medical students in years 2-6 at Jazan University, Saudi Arabia, completed validated questionnaires on IS (Young Imposter Scale) and SE (Rosenberg Self-Esteem Scale). Sociodemographic factors were also collected. Descriptive statistics and logistic regression analyses were used to analyze IS and SE prevalence and correlates. Five hundred twenty-three students with a mean age of 22.09 ± 1.933 participated. The prevalence of low SE and positive IS was 17.6% and 24.3%, respectively. IS and SE had a significant negative correlation (p<0.001). Several sociodemographic factors were associated with increased IS, including 2nd and 4th-year students, forced study choice, and a grade point average (GPA) of 3.0-3.49 (P<0.05). Paternal education beyond high school was associated with lower IS (P<0.05). Logistic regression analyses confirmed that 2nd-year students had a 3.88 times higher odds ratio (OR) (95% confidence interval (CI); 2.19-6.88), and 4th-year students had a 2.37 times higher OR (95% CI; 1.40-4.02) of IS than other years. For SE, advanced academic years, forced study choice, 7+ hours of sleep, and a GPA above 3.5 were associated with higher levels (P<0.05). Negative self-appraisals were associated with lower SE, while positive attitudes were associated with higher SE (P<0.05). Our study reveals that IS and low SE are prevalent among Jazan University, Saudi Arabia, medical students. Therefore, intervention courses that address these issues in medical education at Jazan University, Saudi Arabia, may be necessary to support medical students' well-being and academic success., Competing Interests: The authors have declared that no competing interests exist, (Copyright: © 2024 El-Setouhy et al.

Aim: This study aimed to estimate the national prevalence of developmental delays (DDs) and their determinants among Egyptian children aged 6 to 12 years. Such estimation is a prerequisite step toward the application of Life Skill Education (LSE) programs that will potentiate children's future capabilities., Methods: Vineland Adaptive Behavior Scales" was used as a reliable and diagnostic test for DDs screening during this national cross sectional study. Gross motor (GM), fine motor (FM), daily living skills, communication, and socialization skills were assessed. The multivariate logistic regression analysis was used to identify factors associated with DDs. The Adjusted Odds Ratio (AOR) with a 95% Confidence Interval was estimated to indicate the strength of association. A p-value of <0.05 was used to declare statistical significance., Results: Out of the 20324 surveyed school-aged children, 7.4% were found to have at least one delay. Communication deficits were the most common (6.4%) followed by delay in daily living skills (2.0%). The final model of logistic regression had a good fit for seven variables out of the sociodemographic, epidemiological characteristics, maternal and perinatal problems that were associated with a higher likelihood of at least one DD: Children suffering from any convulsions (AOR = 4.32; 95% CI: 3.18-5.88), male gender (AOR = 1.86; 95% CI: 1.65-2.09), birth weight less than 2.5 kg (AOR = 1.77; 95% CI: 1.40-2.24), history of maternal health problem during pregnancy (AOR = 1.64; 95% CI:1.34-2.01), children staying in an incubator for more than two days (AOR = 1.57, 95% CI: 1.29-1.91), having less educated fathers (AOR = 1.55, 95% CI: 1.24-1.95) and belonging to the middle social class (AOR = 1.40, 95% CI: 1.24-1.58)., Conclusion: The identified types and determinants for each DD are allowing for the implementation of tailored programs for school children's life skills promotion for achieving the most sustainable effects on children's biological and psychological health and well-being., Competing Interests: All authors report no conflict of interest. “No financial or non-financial benefits have been received or will be received from any party related directly or indirectly to the subject of this manuscript., (Copyright: © 2023 Metwally et al.

This study aimed to provide a national estimate of the prevalence of the high risk of autism spectrum disorder (ASD) and their determinants. A national screening survey was conducted for 41,640 Egyptian children aged 1 to 12 years in two phases. Tools used were Vineland's Adaptive Behavior Scales, Modified Checklist for Autism in Toddlers, Gilliam Autism Rating scale, and Denver II Developmental screening test. The overall prevalence of children at high risk of ASD was 3.3% (95% CI:3.1%-3.5%). Children living without mothers in homes, suffered from convulsions (AOR = 3.67; 95%CI:2.8-4.8), a history of cyanosis after birth (AOR = 1.87; 95% CI:1.35-2.59) or history of LBW babies (AOR = 1.53; 95% CI:1.23-1.89) carried higher odds of being at high risk of ASD., (© 2023.

Introduction: Chest imaging plays a prominent role in the assessment of patients with blunt trauma. Selection of the right approach at the right time is fundamental in the management of patients with blunt chest trauma . [1] A reliable, economic, bedside, and rapidly accomplished screening test can be pivotal. [2]., Objective: The aim of this study was to compare the accuracy of extended- focused assessment with sonography for trauma (E-FAST) to that of the National Emergency X-Radiography Utilisation Study (NEXUS) chest algorithm in detecting blunt chest injuries., Methods: This descriptive cross-sectional study included 50 polytrauma patients with blunt chest trauma from the emergency centre of Suez Canal University Hospital. E-FAST and computed tomography (CT) were conducted, followed by reporting of NEXUS criteria for all patients. Blinding of the E-FAST performer and CT reporter were confirmed. The results of both the NEXUS algorithm and E-FAST were compared with CT chest results., Results: The NEXUS algorithm had 100% sensitivity and 15.3% specificity, and E-FAST had 70% sensitivity and 96.7% specificity, in the detection of pneumothorax.In the detection of hemothorax, the sensitivity and specificity of the NEXUS algorithm were 90% and 7.5%, respectively, whereas E-FAST had a lower sensitivity of 80% and a higher specificity of 97.5%., Conclusion: E-FAST is highly specific for the detection of hemothorax, pneumothorax, and chest injuries compared with the NEXUS chest algorithm, which demonstrated the lowest specificity. However, the NEXUS chest algorithm showed a higher sensitivity than E-FAST and hence can be used effectively to rule out thoracic injury., Competing Interests: This work was funded by the National Institutes of Health, Fogarty International Center, Bethesda, MD (grant number, 2D43TW007296).

Background: Type 1 diabetes mellitus (T1DM) patients are at an increased risk for non-alcoholic fatty liver disease (NAFLD). This study aimed to evaluate the clinical criteria associated with the diagnosis of Non-Alcoholic Fatty Liver Disease (NAFLD) among T1DM Egyptian children and adolescents., Methods: 74 T1DM patients aged 8-18 year were enrolled in this cross sectional study. Assessments of Clinical status, anthropometric measures, lipid profile, glycated haemoglobin (HbA1c) and liver enzymes were done. Abdominal Ultrasound evaluation of hepatic steatosis was done. Accordingly, patients were divided into two groups (NAFLD and normal liver group) and compared together. Assessment of liver fibrosis using acoustic radiation force impulse elastography (ARFI) was done. Statistical analysis included; independent t-test, Chi square and Fisher's Exact, Pearson and Spearman tests and Logistic regression models for factors associated with fatty liver were used when appropriate., Results: In this study; 74 patients were enrolled; 37 males (50%) and 37 females with mean age 14.3 ± 3.0 year. The mean insulin dose was 1.1 ± 0.4 U/kg and mean disease duration was 6.3 ± 3.0 year. NAFLD was detected in 46 cases while 28 cases had normal liver as diagnosed by abdominal ultrasound. Cases with NAFLD had statistically significant higher BMI-Z scores, waist/hip, waist/height and sum of skin fold thicknesses compared to those with normal liver (P < 0.05). The mean value of HbA1c % was significantly higher in NAFLD group (P = 0.003). Total cholesterol, triglycerides and LDL serum levels were significantly elevated (p < 0.05), while the HDL level was significantly lower in NAFLD cases (p = 0.001). Although, serum levels of liver enzymes; ALT and AST were significantly higher among cases with NAFLD than in normal liver group (p < 0.05), their means were within normal. Using the ARFI elastography; NAFLD cases exhibited significant fibrosis (F2, 3 and 4). BMI, patient age and female gender were among risk factors for NAFLD., Conclusions: NAFLD represents a serious consequence in type 1 diabetic children and adolescents that deserves attention especially with poor glycemic control. NAFLD has the potential to evolve to fibrosis. This study demonstrated a very high prevalence of NAFLD in T1D children and adolescents using US which was (62.2%) with the percent of liver fibrosis among the NAFLD cases (F2-F4) using ARFI elastography was 26%. BMI, age of patients and female gender were detected as risk factors for NAFLD., (© 2023. The Author(s).)

Background Blunt abdominal trauma (BAT) is the most common pattern of abdominal traumas. It may be associated with intra-abdominal injuries (IAIs). Exploratory laparotomies are only needed in a minority of patients after BAT. Methodology All BAT patients who presented to the El Demerdash Hospital of Ain Shams University, Cairo, Egypt during the study period were traced. Parameters including demographic data, focused assessment with sonography for trauma (FAST) scan, CT scan results, and hematuria were collected. The cohort was divided according to the CT scan results into two groups: patients with IAIs and patients without IAIs. Results Males represented 78.2% of the patients, and the mean age of the recruited patients was 32.1 ± 18 years. Road traffic accidents represented the main cause of trauma (58%) . Patients with IAIs detected by CT scan represented 1.62%, and hematuria was detected in 88.9% of them. The specificity of FAST was 97.1%, and that of hematuria was 84.1%, and for the combination of both tests, the specificity was 99.3%. Conclusion IAIs after BAT can usually be excluded if both FAST and hematuria are negative, provided that the patient is stable., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Abd-erRazik et al.)

Objectives  Cerebrospinal fluid (CSF) leak following endoscopic transsphenoidal surgery (TSS) remains a challenge and is associated with high morbidity. We perform a primary repair with f at in the pituitary f ossa and further fat in the s phenoid sinus (FFS). We compare the efficacy of this FFS technique with other repair methods and perform a systematic review. Design, Patients, and Methods  This is a retrospective analysis of patients undergoing standard TSS from 2009 to 2020, comparing the incidence of significant postoperative CSF rhinorrhea (requiring intervention) using the FFS technique compared with other intraoperative repair strategies. Systematic review of current repair methods described in the literature was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Results  In all, there were 439 patients, with 276 patients undergoing multilayer repair, 68 patients FFS repair, and 95 patients no repair. No significant differences were observed in baseline demographics between the groups. Postoperative CSF leak requiring intervention was significantly lower in the FFS repair group (4.4%) compared with the multilayer (20.3%) and no repair groups (12.6%, p  < 0.01). This translated to fewer reoperations (2.9% FFS vs. 13.4% multilayer vs. 8.4% no repair, p  < 0.05), fewer lumbar drains (2.9% FFS vs. 15.6% multilayer vs. 5.3% no repair, p  < 0.01), and shorter hospital stay (median days: 4 [3-7] FFS vs. 6 (5-10) multilayer vs. 5 (3-7) no repair, p  < 0.01). Risk factors for postoperative leak included female gender, perioperative lumbar drain, and intraoperative leak. Conclusion  Autologous fat on fat graft for standard endoscopic transsphenoidal approach effectively reduces the risk of significant postoperative CSF leak with reduced reoperation and shorter hospital stay., Competing Interests: Conflict of Interest None declared., (Thieme.

Introduction: Trauma deaths account for 8% of all deaths in Egypt. Patients with multiple injuries are at high risk but may be saved with a good triage system and a well-trained trauma team in dedicated institutions. The incidence of missed injuries in the Emergency Centre (EC) of Suez Canal University Hospital (SCUH) was found to be 9.0% after applying Advanced Trauma Life Support (ATLS) guidelines. However, this rate is still high compared with many trauma centers., Aim: Improve the quality of management of polytrauma patients by decreasing the incidence of missed injuries by implementing the Sequential Trauma Education Programs (STEPs) course in the EC at SCUH., Methods: This interventional training study was conducted in the SCUH EC that adheres to CONSORT guidelines. The study was conducted during the one month precourse and for 6 months after the implementation of the STEPs course for EC physicians. Overall, 458 polytrauma patients were randomly selected, of which 45 were found to have missed injuries after applying the inclusion and exclusion criteria. We assessed the clinical relevance of these cases for missed injuries before and after the STEPs course., Results: Overall, 45 patients were found to have missed injuries, of which 15 (12%) were pre-STEPs and 30 (9%) were post-STEPs course. The STEPs course significantly increased adherence to vital data recording, but the reduction of missed injuries (3.0%) was not statistically significant in relation to demographic and trauma findings. However, the decrease in missed injuries in the post-STEPs course group was an essential clinically significant finding., Conclusion: STEPs course implementation decreased the incidence of missed injuries in polytrauma patients. Thus, the STEPs course can be considered at the same level of other advanced trauma courses as a training skills program or possibly better in dealing with trauma patients. Repetition of this course by physicians should be mandatory to prevent more missed injuries. Therefore, the validation of STEPs course certification should be completed at least every two years to help decrease the number of missed injuries, especially in low-income countries and low-resource settings., (© 2022 The Authors.

Background: The frequency of shivering regarding regional anesthesia is 55%. Newer effective and tolerable options for postspinal anesthesia shivering (PSAS) prophylaxis are necessary to improve patients' quality of care. This research assessed the impact of preemptive mirtazapine versus preemptive dexamethasone to decrease frequency and severity of PSAS in gynecological procedures., Methods: 300 patients booked for gynecological procedures under spinal anesthesia (SA) were randomly apportioned into three groups (100 each) to get one preemptive dose of 30 mg mirtazapine tablet (M group), 8 mg dexamethasone diluted in 100 ml of saline infusion (D group) or placebo (C group) two hours before surgery. Incidence of clinically significant PSAS was the primary outcome. Core temperature, shivering score, hemodynamics changes, adverse events, and patient satisfaction score were documented as secondary outcomes., Results: Compared with C group, mirtazapine and dexamethasone decreased incidence of clinically significant shivering (74% vs. 16% and 31%, respectively; P < 0.001). M and D groups had less hypotensive episodes during 5-25 min after intrathecal injection ( P < 0.001). 90 min after SA, tympanic temperatures were lower than baseline values in the three groups ( P < 0.001). Pruritus, nausea, and vomiting were more often in C group ( P < 0.001), whereas sedation was more frequent in M group ( P < 0.001). C group had the lowest satisfaction scores ( P < 0.001)., Conclusion: Prophylactic administration of mirtazapine or dexamethasone attenuated shivering with minimal hazards in patients scheduled for gynecological surgeries under spinal anesthesia with priority to mirtazapine.

Background: Down syndrome (DS) is characterized by variable degrees of intellectual disability (ID). The coronavirus disease-2019 (COVID-19) lockdown prevented children with DS from reaching their rehabilitation facilities. This could have led to deterioration of their abilities and mental health hazards. The aim of this cohort study was to investigate frequency of COVID-19, the influence of COVID-19 pandemic on health, and some abilities of children with DS, and to explore factors that could have governed receiving home-based training during the lockdown. A survey of 150 individuals with Down syndrome was answered by their caregivers. Additionally, 135 participants were subjected to assessment of cognitive, language, and motor abilities using Portage program. They were divided into 2 groups: group I who received online therapy sessions during the lockdown and group II who did not receive sessions. Logistic regression was used to determine the factors which influenced getting home-based training., Results: The percentage of COVID-19 cases was 3.3%. All evaluated abilities were reduced despite receiving online sessions particularly language performance ( P  < 0.001). Male gender, having severe ID and low parental education were among the factors which encouraged parents to get virtual training., Conclusion: COVID-19 pandemic had a negative impact on the abilities of DS children even those who got rehabilitation sessions. Their dependence on social interaction could have limited the benefit of virtual sessions. Factors that influence a parent's decision to get home-based training should be monitored and targeted in order to overcome obstacles or concepts that may prevent families from enduring home-based intervention., Competing Interests: Competing interestsThe authors declare that they do not have competing interests., (© The Author(s) 2022.)

Introduction: "Delayed discharge" is defined as patients who remain hospitalised beyond the time of being fit for discharge after a decision of discharge has been made by the managing team. There is no standardised amount of time defining delayed discharge documented in the literature, and there is a lack of evidence about this topic in Egypt. This study is a quality improvement project aiming to identify the factors associated with discharge delays at a single centre in Egypt in order to address this issue., Methods: A prospective observational study included all trauma patients admitted to a University Hospital in Egypt over two months. The time of the decision of discharge and actual discharge time were recorded by reviewing patients' medical records. The patients and their caregivers were asked to fill in a questionnaire about the reasons for delayed discharge. Potential reasons for the delayed discharge were classified into system-related, medical and family-related factors., Results: The study included 498 patients with a median age of 41 years (9-72). The median time from discharge decision until actual discharge was 3 h. System-related factors were documented in 48.8% of cases, followed by medical factors (36.3%), and family-related factors (28.1%). When controlling for age, gender and injury severity score using a logistic regression analysis, longer time to discharge (≥3 h) showed a stronger association with medical factors [adjusted OR (95% CI) = 5.44 (2.73-10.85)] and family-related factors [adjusted OR (95% CI) = 7.94 (3.40-18.54)] compared to system-related factors [adjusted OR (95% CI) = 2.20 (1.12-4.29)]., Discussion: Although system-related factors were more prevalent, medical and family-related factors appear to be associated with longer discharge delays compared to system-related factors., Competing Interests: The authors declare no conflicts of interest., (© 2018 Published by Elsevier Ltd.

Background: Shivering is known to be a frequent complication in patients undergoing surgery under neuraxial anesthesia with incidence of 40-70%. Although many pharmacological agents have been used to treat or prevent postspinal anesthesia shivering (PSAS), the ideal treatment wasn't found. This study evaluated the efficacy of paracetamol and dexamethasone to prevent PSAS in patients undergoing lower abdominal and lower limb surgeries., Methods: Three hundred patients scheduled for surgeries under spinal anesthesia (SA) were allocated into three equal groups to receive a single preoperative dose of oral paracetamol 1 g (P group), dexamethasone 8 mg intravenous infusion (IVI) in 100 ml normal saline (D group) or placebo (C group), 2 h preoperatively, in a randomized, double-blind trial. The primary endpoint was the incidence of clinically significant PSAS. Secondary endpoints included shivering score, the change in hemodynamics, adverse events (e.g., nausea, vomiting and pruritis) and patients` satisfaction., Results: Clinically significant PSAS was recorded as (15%) in P group, (40%) in D group and (77%) in C group (P < 0.001). The mean blood pressure values obtained over a 5-25 min observation period were significantly higher in the D group (P < 0.001). Core temperature 90 min after SA was significantly lower in the 3 groups compared to prespinal values (P < 0.001). Nausea, vomiting and pruritis were significantly higher in the C group (P < 0.001). P and D groups were superior to C group regarding the patients' satisfaction score (P < 0.001)., Conclusion: Paracetamol and dexamethasone were effective in prevention of PSAS in patients undergoing lower abdominal and lower limb surgeries compared to placebo controls., Trial Registration: ClinicalTrials.gov Identifier: NCT03679065 / Registered 20 September 2018 - Retrospectively registered, http://www.ClinicalTrial.gov ., (© 2021.

Background: Voodoo is a heterogeneous mixture of psychoactive substances that has recently grown in popularity among youth in Egypt. Patients can present with a variety of manifestations that may lead to death in some cases. This study assessed the acute toxic effects of voodoo among patients presented to the Poison Control Center of Ain Shams University Hospitals (PCC-ASUH) during a one year period., Methods: This is a retrospective study of all patients presented with voodoo intoxication at the PCC-ASUH from 1 January 2017 to 31 December 2017. Clinical data, routine laboratory findings, and ECG results as well as duration of hospitalization and outcome were compiled from hospital records., Results: Seventy-one voodoo intoxication cases meeting the inclusion criteria were analyzed (mean age: 25.19 ± 9.54 years, range: 15-50 years, 97.2 % male). Pulse, blood pressure, and respiratory rate were normal in more than half of all patients. Neurological abnormalities including agitation, hallucinations, disturbance of consciousness were the most frequent manifestations. Respiratory acidosis was the most common laboratory finding (54.9 %), followed by increased serum urea (43.6 %), hypokalemia (33.8 %), hyperglycemia (28.1 %), and leukocytosis (26.7 %). The most common ECG finding was sinus tachycardia (31 %), followed by QT prolongation (15.4 %). More than half of the studied patients (53.5 %) co-administered other illicit substances, most frequently cannabis and tramadol. Most patients recovered fully and were discharged, but death occurred in two cases., Conclusions: Voodoo toxicity can manifest with many presentations, hampering timely diagnosis. Clinicians should consider possible voodoo poisoning in patients presenting with a history of drug use with neurological symptoms, and they should conduct follow-up arterial blood gases, electrolytes and ECG as voodoo may contain potentially fatal psychoactive substances., (© 2021.

Since the emergence of SARS-CoV-2 at the end of 2019, 64 candidate vaccines are in clinical development and 173 are in the pre-clinical phase. Five types of vaccines are currently approved for emergency use in many countries (Inactivated, Sinopharm; Viral-vector, Astrazeneca, and Gamaleya Research Institute; mRNA, Moderna, and BioNTech/Pfizer). The main challenge in this pandemic was the availability to produce an effective vaccine to be distributed to the world's population in a short time. Herein, we developed a whole virus NRC-VACC-01 inactivated candidate SARS-CoV-2 vaccine and tested its safety and immunogenicity in laboratory animals. In the preclinical studies, we used four experimental animals (mice, rats, guinea pigs, and hamsters). Antibodies were detected as of week three post vaccination and continued up to week ten in the four experimental models. Safety evaluation of NRC-VACC-01 inactivated candidate vaccine in rats revealed that the vaccine was highly tolerable. By studying the effect of booster dose in the immunological profile of vaccinated mice, we observed an increase in neutralizing antibody titers after the booster shot, thus a booster dose was highly recommended after week three or four. Challenge infection of hamsters showed that the vaccinated group had lower morbidity and shedding than the control group. A phase I clinical trial will be performed to assess safety in human subjects.

Background: COVID-19 (Corona Virus Disease 2019) is showing a wide global spread, and urgent joint international efforts is required to the control of this pandemic, the awareness of people towards infectious viruses still the main factor to limit the widespread of disease. The aim of this study is to assess the level of awareness and attitude towards COVID-19 among a sample of Egyptian school children, using a web-based questionnaire., Results: A total of 708 participants were involved in this online survey study, representing different areas in Egypt, 378 males (53.4%), 330 females (46.5%); their age range between 6 and 18 years. Regarding the residence, 576 (81.4%) were from urban areas, the remaining 132 (18.6%) were from non-urban areas. Internet and media were more frequent used as a source of information in urban students. The knowledge level score of risk and prevention of the disease were significantly higher in urban students than in non-urban students. Healthy practice score ≥ 50 were significantly more frequent in urban students. Healthy practice score was non-significantly higher in urban students., Conclusions: Most of the study participants of school students are knowledgeable about basic information, and have cautious preventive practices towards COVID-19, denoting the efficacy of the public health efforts. However, the lower level of awareness in non-urbans, indicating a need to address alternative channels to communicate with these populations., Competing Interests: Competing interestsThe authors declare that they have no competing interests" in this section., (© The Author(s) 2021.)

Background: Several compounds obtained from plants have potential insecticidal, growth deterrent or repellent characteristics. The control of hard ticks by non-chemical substances was targeted in this study., Methods: The effect of 36 materials on in-vitro ticks was studied, including 2 absolute controls (water only or absolute ethyl alcohol only), 6 conventionally used spinosad preparations (aqueous solutions), 12 Nigella sativa (N. sativa) preparations (aqueous and alcoholic solutions), and 12 Thyme preparations (aqueous and alcoholic solutions). The engorged ticks were tested in-vitro for mortality and oviposition ability using the studied materials., Results: The final mortality after 48 hours of application in N. sativa aqueous preparations began from 10.0% concentration, 1.0% to 100% by concentration preparations ≥10%. In addition, N. sativa alcoholic preparations began from 50.0% concentration, 2 % to 100% by concentration ≥5%. Meanwhile, Thyme aqueous and alcoholic preparations began from 70.0% concentration, 5% to 90% by concentration 10-20%. Additionally, spinosad aqueous preparations and both of control preparations (Water and Alcohol) resulted in no mortality. All differences were statistically significant. The oviposition was stopped in N. sativa (aqueous ≥10% and alcoholic ≥5%) and in spinosad (aqueous≥25%). The aqoues dilution of the used matters killed B. annulatus larvae beginning from the concentration 5%., Conclusion: Nigella sativa alcohol 20% was the best of studied preparations being the lowest concentration (20%) that could achieve the highest lethal (100%) effect in shortest time (12 hours). Moreover, Thyme oil and spinosad could not kill 100% of adult but did on larvae.
