For high risk prostate cancer, the treatment volumes and even dose levels are still a controversial issue. The aim of this study is to evaluate the dosemetric parameters and acute toxicity of dose-escalated whole pelvis (WP) Intensity Modulated Radiation Therapy (IMRT) and volumetric modulated arc therapy (VMAT) prostate boost following neoadjuvant and concomitant with androgen deprivation therapy in high-risk prostate cancer patients. This analysis included 73 high-risk prostate cancer patients treated with WP-IMRT followed by boost to the prostate by VMAT to total dose of 80 Gy;between January 2014 and October 2016. Androgen deprivation therapy (ADT) was given for all patients before and during radiation therapy. Drawing the dose volume histograms (DVHs) was done for planning target volumes (PTVs), including Prostate PTV & nodal PTV, and organs at risk including rectum, bladder, femoral heads, and bowel bag for the plans. Acute radiation toxicities were reported during the radiation course and the following 3 months. The DVH analysis showed good coverage of PTVs and organs at risk doses were acceptable. No recorded acute Grade ≥ 3 toxicity. Acute grade 1 toxicity for Gastrointestinal (GI) and Genitourinary (GU) were 65% and 35% respectively, while Grade 2 toxicity was 30% for both. The Proctitis and frequency were the commonest acute toxicity and were maximal during the 5th week of radiation therapy. Dose escalation in two phases utilizing Simultaneous integrated boost (SIB) combined with ADT in high risk prostate cancer patient is feasible and associated with acceptable acute GI and GU toxicity.

Traffic accidents constitute the substantial cause of disability and mortality in the young Saudi individuals reaching horrible figures. The aim of this study was to review and identify the pattern of injury among road traffic accident (RTA) victims as well as the peak time of accidents and their implications. This retrospective hospital-based cross-sectional study was carried out in the period between April 2016 to March 2017 in King Khalid Hospital, Maternity and Children Hospital and Najran General Hospital, Najran, Saudi Arabia. all RTA victims admitted to the emergency departments of the pre-mentioned hospitals. Data collected from 435 Saudis and non-Saudis’ files were statistically analyzed with regard to age, gender, the timing of road traffic accidents, injury pattern, and neurological deficits incidence. Most of the RTAs’ cases (92%) were male victims with the highest peak in the age group 20 - 29 years. 58% of the RTAs happened in the evening (6:00 PM-9:00 PM) while 20% occurred in the morning. Head injury represented the most frequent pattern (36%) followed by the spinal injury (23%), lower limb injury (23%), upper limb injury (20%), thoracic injury (17%), pelvic injury and abdominal injury (8%). 4.4% of RTAs resulted in death whilst 9% of cases experienced neurological deficits. In conclusion, young male drivers in Najran recorded the highest frequency of RTAs. Initiation of road safety education and expansion of speed detectors (Saher) system deployment is highly recommended.

Lead （Pb） is one of the most common environmental toxicants, exposure to which can cause significant neurotoxicity and an associated decline in brain function. This study investigated the possible neuroprotective role oflndigofera oblongifolia leaf methanolic extract （IOLME） against lead-induced neurotoxicity. Rats were intraperitoneally injected with lead acetate, with or without IOLME （intragastric administration for 5 days）, and the neuroprotective effect of IOLME was assessed by measuring the lead concentration, redox status （lipid peroxidation, nitric oxide and glutathione）, enzymatic antioxidant activities （superoxide dismutase, catalase, glutathione peroxidase and reductase）, PCR assays of apoptosis markers （Bax and Bcl-2） and histopathology of the brain. The increases in the lipid peroxidation, nitric oxide, and apoptosis, the decreases in the glutathione level and the activity of antioxidant enzymes, and the altered histology of the brain induced by lead acetate were mitigated in the brain of rats pre-treated with IOLME. These findings indicate that IOLME has beneficial effects and it mitigates lead acetate-induced neurotoxicity via its antiox-idant and anti-apoptotic activities.
