The relationship between illnesses and medical drug consumption with the occurrence of traffic accidents among truck and bus drivers in Tehran, Iran

Purpose: To determine the relationship of illnesses and medical drug consumption with the occurrence of traffic accidents among truck and bus drivers. Methods: This is a cross-sectional study on truck and bus drivers in Tehran, Iran. The criteria for participating in this study were: married males over 30 years old, driving license in grade one, five years of job experience, mental health and non-addiction license. The criterion for not participating in this study was the lack of cooperation in responding to the questions. Six months was spent to collect the latest five years data of driving accidents from 2011 to 2016. A total of 323 truck and bus drivers in Tehran city and the suburbs, Iran were chosen. Among them, 112 were responsible for accidents (accident group) while 211 were not responsible for any accidents or involved in an accident in the last five years (nonaccident group). A specially designed questionnaire was used to investigate the demographic information, medical drug consumption, medical backgrounds and history of accidents. Results: The results revealed that compared with healthy subjects, the occurrence of accidents among people with diabetes (OR = 2.3, p = 0.001) and vision weakness (OR = 1.7, p = 0.020) was significantly higher, while that among people with cardiac (OR = 0.5, p = 0.002) and hypertension (OR = 0.9, p = 0.048) problems was remarkably lower. Moreover, consumption of Gemfibrozil (OR = 1.8, p = 0.010) and Glibenclamide (OR = 2.2, p = 0.002) drugs resulted in significantly higher incidence of accidents than those without. Conclusion: Frequencies of illnesses like cardiovascular and hypertension were not higher in accident drivers than in non-accident drivers; but diabetes, vision weakness and consumption of Gemfibrozil and Glibenclamide lead to more traffic accidents.     

Delusional parasitosis as presenting symptom of occipital lobe cerebrovascular accident

Delusional parasitosis manifests as a fixed, false belief that an individual is infested by living organisms. Primary delusional parasitosis is a psychiatric disorder with the delusion as an isolated manifestation, whereas secondary delusional parasitosis is a delusion occurring secondary to a psychiatric disorder, substance use, or medical illness. A 62-year-old woman with no psychiatric history presented to the Emergency Department with two to three months of “whole body itching” and seeing small insects crawling on her skin and in her hair. Exam of her skin and scalp was notable for no appreciable lesions, rashes, excoriations, or insects. Her neurologic exam was notable for full visual fields, and no localizing deficits. A non-contrast head CT demonstrated a nonspecific heterogeneous low-attenuation lesion within the medial right occipital lobe, and a follow up MRI confirmed a right posterior cerebral artery distribution subacute infarction. She was admitted for two days, and ultimately was discharged on aspirin and atorvastatin for secondary prevention. An emergency physician should remain vigilant in his/her assessment of patients with seemingly psychiatric symptoms, in particular elderly patients with no known psychiatric illnesses. Neuroimaging should be amongst studies considered in the evaluation of elderly patients presenting with new onset psychiatric complaints.     

Outcome of sentinel lymph node biopsy in early-stage squamous cell carcinoma of the oral cavity with methylene blue dye alone: a prospective validation study

Our aim was to evaluate the feasibility and role of sentinel lymph node (SLN) biopsy using methylene blue dye alone in identifying occult lymph node metastases in early oral cancer (cT1, T2, and cN0). The study was done from 2013–15 in 94 patients in a large cancer centre. The blue nodes were dissected and sent for frozen section, routine histopathological examination, and immunohistochemical testing for cytokeratin, and was followed by elective neck dissection in all patients. The identification rate was 93.61%. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for frozen section and haematoxylin and eosin (H&E) staining were 84.6%, 100%, 100%, 93.9% and 95.5%, respectively. Occult lymph node metastasis was seen in 27.6% cases. Biopsy of SLN with blue dye alone might be used successfully with good sensitivity and negative predictive value in countries with limited resources in the developing world. Immunohistochemistry contributes to it by increasing the sensitivity and NPV, and thereby improves the diagnostic value.     

A unique case of bradycardia recognized by wearable technology as first presentation of complete heart block

Wearable technology has advanced significantly, and the proposed health benefits have been widely touted. Most of the discussion has been surrounding the identification and diagnosis of asymptomatic atrial fibrillation. However, the heart monitoring functions of the wearable technology can also identify other abnormalities as well. We present the first case of wearable technology identified bradycardia diagnosed as the primary presentation of complete heart block. Wearable technology has advanced significantly, but still poses questions regarding its use in screening for rare conditions. One remaining challenge is balancing the desire to screen for rare asymptomatic conditions without overburdening emergency departments with patients responding to alarms on their devices.     

基于时滞关联特征患者就诊反馈分析

抓取“微医网”医患评论数据，对其中时滞与患者满意度进行关联分析，并对评论内容进行主题挖掘，提取不同时滞区间内患者重点关注的内容。通过对患者评论文本不同时滞区间内容的分析，寻找满意度提升策略，以缓解医患关系。使用K-means将患者反馈数据根据就诊后时长反馈分为“短期”和“长期”，通过LDA主题提取模型，对满意度划分后的患者评论文本挖掘不同时滞区间内患者所关注的重点内容，将其差异进行对比分析发现，患者就诊满意度随着时滞呈现趋高现象，不同时滞文本显示患者评论维度大致相同，但随着时滞区间的转移，患者所关注的就诊体验内容也有所变化。
