RESUMO

This study analyzed physical violence against physicians in Egypt from a medicolegal perspective. 88%, 42%, and 13.2% of participants were exposed to verbal, physical, and sexual violence. Concerning the tools of violence, 75.2% of attackers used their bodies. Blunt objects (29.5%), sharp instruments (7.6%), and firearm weapons (1.9%) were used. The commonest manners of attacks were pushing/pulling (44.8%), throwing objects (38.1%), and fists (30.5%). Stabbing (4.8%) and slashing (2.9%) with sharp instruments were also reported. Traumas were mainly directed towards upper limbs (43.8%), trunks (40%), and heads (28.6%). Considering immediate effects, simple injuries were reported that included contusions (22.9%), abrasions (16.2%), and cut wounds (1.9%). Serious injuries included firearm injuries (4.8%), internal organs injuries (3.8%), fractures (2.9%), and burns (1.9%). Most (90.5%) of injuries healed completely, whereas 7.6% and 1.9% left scars and residual infirmities, respectively. Only 14.3% of physicians proceeded to legal action. The current study reflects high aggression, which is disproportionate to legal actions taken by physicians. This medicolegal analysis could guide protective measures for healthcare providers in Egypt. In addition, a narrative review of studies from 15 countries pointed to violence against physicians as a worldwide problem that deserves future medicolegal analyses.

RESUMO

BACKGROUND: Sal-like protein 4 transcription factor (SALL4) and B cell-specific Moloney murine leukemia virus integration site 1 (BMI-1) gene were reported to cause treatment failure and relapse in several malignancies. We aimed to evaluate the prognostic value of SALL4 and BMI-1 in children with acute lymphoblastic leukemia (ALL). METHODS: This prospective cohort study was carried out on 60 children with ALL as the patient group and 60 age- and sex-matched children as the control group. We evaluated the expression pattern of both SALL4 and BMI-1 genes in the peripheral blood using real-time reverse transcriptase-polymerase chain reaction in children with ALL at initial diagnosis before chemotherapy. We followed up with the patient group for 2 years for relapse or death. RESULTS: Both SALL4 and BMI-1 were overexpressed in ALL children compared to the control group. Moreover, the expression of SALL4 and BMI-1 in patients with relapse was significantly higher than those with complete remission. The best cut-off of SALL4 and BMI-1 to predict relapse were >2.21 and 0.55 yielding sensitivity of 92.3% and 84.6%, respectively. Patients with overexpression of SALL4 and BMI-1 had significantly shorter overall and disease-free survival. CONCLUSIONS: SALL4 and BMI-1 could be useful prognostic markers in children with ALL to predict relapse.

RESUMO

Restoring information obstructed by hair is one of the main issues for the accurate analysis and segmentation of skin images. For retrieving pixels obstructed by hair, the proposed system converts dermoscopy images into the L*a*b* color space, then principal component analysis (PCA) is applied to produce grayscale images. Afterward, the contrast-limited adaptive histogram equalization (CLAHE) and the average filter are implemented to enhance the grayscale image. Subsequently, the binary image is generated using the iterative thresholding method. After that, the Hough transform (HT) is applied to each image block to generate the hair mask. Finally, the hair pixels are removed by harmonic inpainting. The performance of the proposed automated hair removal was evaluated by applying the proposed system to the International Skin Imaging Collaboration (ISIC) dermoscopy dataset as well as to clinical images. Six performance evaluation metrics were measured, namely the mean squared error (MSE), the peak signal-to-noise ratio (PSNR), the signal-to-noise ratio (SNR), the structural similarity index (SSIM), the universal quality image index (UQI), and the correlation (C). Using the clinical dataset, the system achieved MSE, PSNR, SNR, SSIM, UQI, and C values of 34.7957, 66.98, 42.39, 0.9813, 0.9801, and 0.9985, respectively. The results demonstrated that the proposed system could satisfy the medical diagnostic requirements and achieve the best performance compared to the state-of-art.

RESUMO

OBJECTIVES: Omega 3 polyunsaturated fatty acids are dietary factors with several beneficial cardiovascular effects. This study aimed to assess the possible protective effect of omega 3 fatty acids on early doxorubicin-induced cardiac toxicity in children with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS: Sixty children of newly diagnosed ALL were randomized into two groups: group I (n = 30) who received omega 3 fatty acids 1000 mg/day for 6 months in addition to their usual protocol of chemotherapy including doxorubicin; and group II (n = 30) who received their usual doxorubicin protocol during the period from February 2020 till August 2021. Echocardiographic examinations were performed before and after the treatment. Glutathione, malondialdehyde (MDA), superoxide dismutase (SOD), troponin I, creatine kinase MB (CK-MB), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured also before and after omega 3 treatment. RESULTS: After 6 months of omega 3 administration, group I had a significantly lower MDA level and a significantly higher glutathione and SOD levels than group II. Similarly, the levels of troponin I, CK-MB, and NT-proBNP were significantly high in group II, whereas they were unchanged in group I after treatment. Similarly, systolic function (presented with peak mitral annular systolic velocity and two-dimensional global longitudinal strain) of the heart was preserved in omega 3-treated patients, unlike the control group that showed significant impairment of left ventricular function after 6 months. CONCLUSION: Omega 3 fatty acids may decrease early cardiac injury and doxorubicin-induced cardiotoxicity in children with ALL.

RESUMO

AIMS AND BACKGROUND: Reduction of overall treatment time of postoperative irradiation and evaluation of the feasibility and preliminary toxicity of an accelerated hypofractionated whole breast irradiation with an addition of a concomitant daily boost in patients with early breast cancer submitted to conservation surgery. MATERIALS: Between June 2010 and September 2011, 122 patients underwent accelerated hypofractionated adjuvant radiation after conservation surgery (pT1 or pT2, pN0-N1). Radiotherapy consisted of 45 Gy, to the whole breast in 20 fractions with 2.25 Gy/fraction; an additional daily boost dose of 0.25 Gy was concomitantly delivered to the lumpectomy cavity, total dose 5Gy. Toxicity was assessed at the end of radiation therapy and at 3, 6, and 12 months using the RTOG/EORTC toxicity scale. Cosmetic results were assessed in agreement with the Harvard criteria. RESULTS: Median follow-up was 31 months, 74% showed grade 0-1 skin toxicity, 20% grade 2, and 6% grade 3. At 3 months of follow-up, grade 0 skin toxicity was observed in 51% of cases; grade 1 in 36%, and grade 2 in 13%. At 6 months, late skin and subcutaneous tissue toxicities were scored as grade 0 in 71%, grade 1 in 18%, and grade 2 in 11% of patients. At 1 year almost all the patients showed grade 0-1 skin toxicity. 97% of patients showed excellent or good cosmetic results. CONCLUSIONS: Accelerated hypofractionated radiotherapy for early breast cancer with concomitant electron boost seems to be feasible providing consistent clinical results with acceptable toxicity profile.

RESUMO

BACKGROUND: O6-methylguanine-DNA methyltransferase (MGMT) protein expression using immunohistochemical analysis was proposed as a prognostic marker for patients with newly diagnosed glioblastoma (GBM) treated with radiation therapy with concurrent and adjuvant Temozolomide (TMZ). METHODS: From April 2012 to October 2014, 73 patients with newly diagnosed GBM, MGMT protein expression were analyzed in formalin-fixed, paraffin-embedded tumor specimens. Patients received the radiation therapy plus concomitant and adjuvant TMZ chemotherapy. RESULTS: For the whole cohort, the median overall survival (OS) was 15 months, and the progression-free survival was 10 months. Patients who had low MGMT protein expression (⩽15%) had a significantly improved OS and PFS compared with patients who had high MGMT expression (17.0 months vs 14 months; P value .006) and (15.0 months vs 10 months; P value .016) respectively. The age and extent of tumor resection were the strongest clinical predictors of outcome. In multivariate Cox models MGMT protein expression, extent of tumor resection and age were identified as independent prognostic factors. CONCLUSIONS: MGMT expression was identified as positive prognostic factor in patients with newly diagnosed glioblastoma who underwent surgical resection followed by adjuvant radiotherapy and concomitant oral TMZ chemotherapy (the Stupp protocol).
