Study of the Pattern and Frequency of Road Traffic Injuries in Car Occupants in the Eastern Part of Iran

Background: Since Iran has one of the highest mortality rates of car accidents in the world, the study of the pattern and reasons of trauma in car occupants can provide useful information to determine the underlying causes of injuries and deaths in traffic accidents. Accordingly, this study was conducted to determine the pattern, frequency, and causes of traumatic injuries caused by traffic accidents in car occupants.Methods: This cross-sectional study was conducted during the first 6 months of 2017 in Shahid Beheshti Hospital in Sabzevar City, Razavi Khorasan Province, Iran. The data were obtained from the medical records of patients and the checklist designed by our research team. Results: During the period of study, 300 people were involved in car accidents, of whom 58.3% were men with an average age of 35.16 years. In both sexes, 29.3% of the subjects were in the age group of 30-40 years. Twenty-two car occupants were involved in non-injury car accidents. No significant relationship was found between traumatic injuries and variables of sex, seatbelt use, airbag deployment, and the seat occupant in the cars (P>0.05), as well as between death and variables of sex, airbag deployment and seat occupant in cars (P>0.05). But there was a significant relationship between death and fastening seat belts (P=0.003). Conclusion: The results of this study revealed that sex, airbag deployment, and seat occupant had no effect on traumatic injury or mortality rate in the car occupants. However, fastening the seatbelt can reduce the mortality rate in car occupants, but it does not impact the traumatic injuries rate

Organophosphorus Insecticide Poisoning Related Mortality and Neurotoxicity in Sabzevar

Background: This study aimed to assess mortality and neurotoxicity caused by the pesticide organophosphate and its correlation with the type of poison and treatment in patients admitted to Vasei Hospital of Sabzevar City, Iran, in 2018.Methods: Out of 122 cases, 52 patients (43.3%) were male, and 70 patients (56.9%) were female. The Mean±SD age of the men was 32.65±29.15, and women was 30±15.30 years.Results: Mortality in women and men was 10% and 17.3%, respectively. Among treated people, diazinon had the highest frequency of 76.4%, and among dead people from diazinon and malathion had the highest rates of 56.3% and 43.8%, respectively. Conclusion: The prevalence of mortality in patients was 7.3% (n=9). As most people with organophosphorus poisoning have been exposed to diazinon toxins; therefore, strategies to prevent and reduce exposure to this toxin are essential

Pathologic Fracture as Primary Presentation of Malignant Pheochromocytoma: A Case Report

Pheochromocytoma is a relatively rare tumor with no age preference. This tumor is usually diagnosed accidentally.  Pathologic fracture as the primary presentation of malignant pheochromocytoma is an uncommon presentation. The present case is a 23 year old man with malignant pheochromocytoma that his first chief complaint was bone pain due to pathological fracture. The presence of bone lesions as the first manifestation of pheochromocytoma makes this case a quite unusual one.

Primary duodenal malignant melanoma: A case report

Background: Melanoma is a neoplasm derived commonly from melanocytic cells of skin. Although coetaneous presentation of malignant melanoma is easily recognizable, the presentation of melanoma in other organs is so confusing. In particular, when it metastasizes to other organs, many bizarre figures and unusual organs may be involved. In this report, we present a case of primary duodenal malignant melanoma. Case Presentation: A 68-year-old man presented with a history of iron deficiency anemia. The upper gastrointestinal endoscopy showed a prominent papilla of duodenum along with an ulcerative lesion adjacent to second part of duodenum. Histopathologic evaluation showed a high-grade malignant neoplasm involving the bowel wall which was labeled for S100 protein and markers of melanocytic differentiation; Melan-A indicating the definitive diagnosis of malignant melanoma of the second portion of duodenal mucosa. Conclusions: In patients with a history of iron deficiency anemia, any GI symptom should be evaluated carefully. However, the diagnosis of primary GI melanomas in patients without any history of melanoma is possible. Full medical investigations are recommended in these patients with primary mucosal lesions

A randomized clinical trial on the anti-tumoral effects of low molecular weight heparin in the treatment of esophageal cancer

The current treatment approaches for esophageal cancer are associated with poor survival, and there are ongoing efforts to find new and more effective therapeutic strategies. There are several reports on the antitumoral effects of low‐molecular‐weight heparins (LMWHs). We have assessed the possible survival benefit of LMWHs in esophageal malignancies. This was a randomized, single‐blind, multicenter, Phase II clinical trial on nonmetastatic esophageal cancer candidate for neoadjuvant chemoradiotherapy. Patients were randomly assigned to the chemoradiotherapy‐only arm or chemoradiotherapy plus enoxaparin arm using 1:1 allocation. Radiotherapy was delivered in 1.8‐Gy daily fractions to a dose of 50.4 Gy in both groups. Paclitaxel 50 mg/m2 and carboplatin (AUC 2) were administered weekly, concurrent with radiotherapy. In the intervention group, patients received enoxaparin (40 mg) and chemoradiation daily. 4–6 weeks after treatment, all patients underwent esophagectomy. After a median follow up of 7 months, estimated 1 year disease‐free survival (DFS) in the intervention group was 78.9% and was 70% in the control groups ( p = 0.5). Toxicity from the experimental treatment was minimal, and there were no treatment‐related deaths. A pathologically complete response in intervention and control group was 64.8% and 62.5%, respectively ( p = 0.9). There was a nonsignificant trend toward improved survival by the addition of enoxaparin to the concurrent chemoradiotherapy regimen. However, 1 y DFS of both groups were high as expected. A longer follow‐up and a larger sample size are required.delivered in 1.8-Gy daily fractions to a dose of 50.4 Gy in both groups. Paclitaxel 50 mg/m2 and carboplatin (AUC 2) were administered weekly concurrent with radiotherapy. In the intervention group, patients received enoxaparin (40 mg) daily as well as chemoradiation. Four to six weeks after treatment, all patients underwent esophagectomy. After a median follow up of 7 months,estimated one year disease free survival (1y DFS) in the intervention group was 78.9% and in the control groups was 70% (p=0.5).
