Buerger’s disease, also called thromboangiitis obliterans (TAO), is an inflammatory disease affecting small and medium size blood vessels of the limbs. Several risk factors are strongly associated with this disease. In fact, heavy smokers represent 99% of patients diagnosed with Buerger’s disease and smoking cessation can slow down the progression of the pathology. Ulcers and gangrene are very common complications and TAO may also cause a vasculitis as well as ischemic damage to the distal part of the limbs that can eventually lead to limb amputation. Here, we report the case of a 43 years old patient, a flight personnel working in a Tunisian airline company who consults for a lesion of the left toe that appeared 2 weeks ago. He is a chronic inveterate smoker with 36 pack-years. The diagnosis of TAO was made based on the clinical presentation and the results of the Doppler Ultrasound of the left toe. This disease has a major impact on the quality of life due to the risk of necrotic ulcers and amputation. Navigation is a profession that requires a high level of physical and mental fitness. According to the international and Tunisian standards, the applicant or the holder of medical certificate must not have a cardiovascular condition that may affect the safety of the exercise.

藏东昌都地区阿涅塘化石点中侏罗世达布卡组滨湖相紫红色中-细砂岩中,发现以凸形迹完好地保存的4层恐龙足迹,包括Grallator类、大型兽脚类、小型兽脚类和小型蜥脚类等足迹类型,并构成两列完美的行迹.组成行迹T1的4个Grallator类足迹被命名为Grallator anietangensis ***.,对其进行了详细的形态学分析,并讨论了造迹恐龙的大小和运动状态,这是Grallator类足迹在西藏地区的首次发现.组成行迹T2的9个大型兽脚类足迹被归为Theropoda *** ***.,对该类足迹进行了形态描述和功能分析;这类足迹在中国是首次记录,其连续且清晰的尾迹表明造迹者并非处于正常运动状态,而是应对某种特殊境况的特别行为方式,即其正以昂起的前躯一边观察,一边以极低的速度前进,因前躯昂起,尾部相应下垂,从而留下尾迹.两列行迹均显示出造迹者正沿古昌都湖岸前进.中国迄今所发现的恐龙骨骼和Grallator类足迹化石主要表现为以西南地区为中心,再向四周不断发散的扩散模式,但Grallator类足迹化石综合提供的信息显示恐龙动物的扩散速度比骨骼化石反映的速度更快.

Introduction: Autonomic nuclei affection results in variations in hemodynamics, temperature, sweating and ECG. Medullary strokes are challenging in their presentation, bizarre clinical signs, work and neurological outcome. The commonest cause is infarction of the posterior inferior cerebellar artery (PICA). Anatomical areas affected include the inferior cerebellar peduncle, dorsolateral medulla, nuclei of the Trigeminal, vestibular nuclei, Ninth and Vagus nerves. The descending sympathetic tracts and spin thalamic tracts. Serious cardiopulmonary events can complicate 11% of cases. Case Presentation: A middle-aged female developed sub-acute dizziness associated with vomiting and right head pains. She was unable to walk but remained cognitively clear. Her gastrointestinal symptoms were disabling and this was the main factor for presenting to the emergency room. The risk factors included hypertension and diabetes mellitus. Imaging studies were essential for posterior circulation stroke diagnosis and follow-up. She manifested remarkable autonomic features regarding the skin and hemodynamics. Nevertheless, the hospital course was controllable. Discussion: This case report was consistent with relevant literature in the contra lateral vaso motor changes and drop in body temperature during the acute phase. Moreover, our patient developed clinical and radiological extension through double antiplatelets. Superiority of the magnetic resonance imaging (MRI) scans in this patient enabled better diagnostic accuracy in a brainstem stroke. Conclusion: The autonomic features, in this case, represent major symptomatology and clinical signs. The variation in the hemodynamics and persistence of symptoms is thought provoking. This increases the awareness of emergency doctors for acute stroke presenting with autonomic features will enable early detection and helps outcome.

Tarlov cysts are often asymptomatic and incidentally discovered. However, in few cases, these cysts can be symptomatic and may manifest as chronic low back pain. We report a case of a Tarlov cyst incidentally diagnosed by MRI in a wiring factory worker complaining of chronic low back pain exacerbated with the carrying of heavy loads and the hyper solicitation of the lumbar spine during his professional activity. The clinical manifestations of symptomatic Tarlov cysts can influence the life quality of patients and have enormous repercussions on their work ability, which in some cases can lead to job loss. Thus, the socio-professional aspects of symptomatic Tarlov cysts should not be underestimated and maintaining these patients in employment should be considered from the outset as an objective in its own right in the management.
