RESUMO
Some studies suggested that gastrointestinal (GIT) decontamination with oil may improve the prognosis of patients who ingested aluminum phosphide (AlP). The aim of this study is to compare the efficacy and safety of gastric lavage with oil-based solutions to any method of gastric decontamination not using oils in patients presenting with acute AlP poisoning. The literature was searched for English-published randomized controlled trials (RCTs) from inception to 16 September 2023. The searched electronic databases included MEDLINE/PubMed, Cochrane Library, Web of Science, Egyptian Knowledge Bank, Scopus, and Google Scholar. Data were extracted and pooled by calculating the risk ratio (RR) for categorical outcomes and standardized mean difference (SMD) for numerical outcomes, with 95% confidence intervals (CI). Seven RCTs were included. Paraffin oil was significantly associated with a lower risk of mortality (RR = 0.59 [95% CI: 0.45, 0.76], p < .001), intubation (RR = 0.59 [95% CI: 0.46, 0.76], p < .001) and vasopressor need (RR = 0.71 [95% CI: 0.56, 0.91], p = .006). Survival time was significantly prolonged with paraffin oil (SMD = 0.72 [95% CI: 0.32, 1.13], p < .001). Coconut oil was significantly associated with prolonged survival time (SMD = 0.83 [95% CI: 0.06, 1.59], p = .03) as well as decreased risk of requiring intubation (RR = 0.78 [95% CI: 0.62, 0.99], p = .04). Oil-based GIT decontamination using paraffin oil showed benefits over conventional lavage regarding the incidence of in-hospital mortality and endotracheal intubation, and survival time. Coconut oil showed some benefits in terms of the intubation incidence and survival time. Decontamination using paraffin oil is recommended. Future clinical trials are warranted with larger sample sizes and focusing on cost-benefit and safety.

This systematic review and meta-analysis pool evidence available from clinical trials to verify the effect of antioxidants on the outcome of acute aluminum phosphide (AlP) poisoning. A systematic review complied with "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) Protocols. Meta-analysis was conducted on 10 studies that fulfill eligibility criteria. Four antioxidants were implemented: N-Acetyl cysteine (NAC), L-Carnitine, Vitamin E, and Co-enzyme Q10 (Co Q10). Risk of bias, publication bias, and heterogeneity were assessed to ensure the results' reliability. Antioxidants significantly decrease mortality of acute AlP poisoning around three folds (OR = 2.684, 95% CI: 1.764-4.083; P < .001) and decrease the need for intubation and mechanical ventilation by two folds (OR = 2.391, 95% CI 1.480-3.863; P < .001) compared with control. Subgroup analysis revealed that NAC significantly decreases mortality by nearly three folds (OR = 2.752, 95% CI: 1.580-4.792; P < .001), and vitamin E significantly decreases mortality by nearly six folds (OR = 5.667, 95% CI: 1.178-27.254; P = .03) compared with control. L-Carnitine showed a borderline significance (P = .050). Co Q10 decreased the mortality compared with the control; however, the difference was not statistically significant (P = .263). This meta-analysis provides solid evidence regarding the efficacy of antioxidants in improving the outcome of acute AlP poisoning with reference to NAC. Wide confidence interval and small relative weight affect reliability regarding vitamin E efficacy. Future clinical trials and meta-analyses are recommended. To our knowledge, no previous meta-analysis was conducted to investigate the efficacy of treatment modalities for acute AlP poisoning.
RESUMO
Background: Aluminum phosphide is a highly toxic pesticide that results in high mortality. To date, there is neither a definitive antidote nor a unified protocol for managing acute aluminum phosphide poisoning. Objectives: This cross-sectional questionnaire-based study aims to explore different management approaches and rely on the expertise of Egyptian medical professionals to enhance the prognosis for acute aluminum phosphide poisoning. Subjects and methods: A self-administered questionnaire was formulated and electronically distributed according to published literature and experience of senior physicians. Results and conclusions: Responses were received from 151 physicians from 10 governorates. Management modalities were variable among respondents. Noradrenaline was used by 90.7% of respondents with no fixed-dose regimen. In all, 84.1% of participants utilized oil in gastrointestinal decontamination; paraffin oil was the most used solution. Overall, 92.1, 61.6, 46.4, and 34.4% of participants used sodium bicarbonate, proton pump inhibitors, IV magnesium sulfate, and antioxidants, respectively. Regarding the frequency of acute aluminum phosphide poisoning, 47% of participants managed these cases daily or a few times a week. Participants' responses denoted a poor prognosis of acute aluminum phosphide poisoning, and high percentages attributed the prognosis to exposure factors rather than treatment modalities. Statistical analysis revealed that using oil in gastrointestinal decontamination improved the outcome by 4.62-fold. Clinical toxicologists were more likely to rescue ≥ 30% of the cases about 3-fold (2.97) than other specialties. Clinical toxicologists used oil in gastrointestinal decontamination, magnesium sulfate, and antioxidant therapy and calculated base deficit before administration of sodium bicarbonate by 7.70-, 5.30-, 3.26-, and 2.08-fold than other specialties.
RESUMO
BACKGROUND: In forensic sciences to determine one's sex is quite important during the identity defining stage. The reliability of sex determination depends on the completeness of the remains and the degree of sexual dimorphism inherent in the population. Computed Tomography is the imaging modality of choice for two- and three-dimensional documentation and analysis of many autopsy findings. OBJECTIVE: The aim of the present work was to assess the reliability of Three-dimensional Multislice Computed Tomography (3D MSCT) to determine sexual dimorphism from certain chest measurements; sternum and fourth rib using the 3D MSCT and to develop equations for sex determination from these bones among adult Egyptians sample. SUBJECTS AND METHODS: The present study was performed on 60 adult Egyptians. Their age ranged from 21 up to 74 years and they were equally divided between both sexes. Sixty virtual chests (reconstructed Multislice Computed Tomography 3D images) were examined for detection of Sternal measurements; Manubrium length (ML), Sternal body length (BL), Manubrium width (MW), Sternal body widths(BWa&BWb), Sternal area (SA) [(ML + BL) × (MW + BWa + BWb)/3]and Fourth rib width (FRW). RESULTS: All the studied measurements were significantly higher in males than in females. Multiple regression analysis was used to and three significant regression equations were developed for predicting sex using the different studied chest measurements; the sternal measurements, the sternal area and the widths of the right and left fourth ribs with their accuracies 96.67%.95.0%.72.68% respectively. CONCLUSION: Sterunm and fourth rib width revealed significant metric sex differences with the use of Multislice Computed Tomography 3D images thus provide a great advantage in the analysis of skeletal remains and badly decomposed bodies.
