A 15-year-old boy presented with a gunshot wound in the left cerebellar hemisphere. He was confused and left cerebellar signs were noted. The patient underwent the first surgery for debridement of the entry wound in the left parietal region and second surgery to remove the bullet. However, the bullet could not be located via a left unilateral suboccipital craniectomy in the park bench position,...

A 35 years old man presented with Cauda Equina syndrome caused by a bullet migrating down the spinal canal. The patient initially showed no neurological deficits after the gunshot injury but after 15 months he presented again with urinary and fecal incontinence. Lumbo-sacral X-ray showed a bullet at the level of L5-S1 so he was operated under fluoroscopic guidance. Patient's neurological defici...

We report the case of a 24 year old male who had a retained bullet within his thoracic spine from a gunshot wound resulting in paraplegia. After 7 months he began experiencing painful dysesthesias at his sensory level. Repeat imaging demonstrated migration of the bullet as well as the development of intramedullary dystrophic calcification associated with the bullet. This case demonstrates not o...

Bullet embolism is a well-known but relatively uncommon complication of gunshot injuries. Their rarity and the potential lack of early symptoms lead to delays in diagnosis and often in inadequate early management that can potentially result in the loss of a limb or life. We present an interesting case in which a small caliber bullet to the upper anterior abdomen penetrated the thoracic aorta an...

The so-called "pristine" bullet (Warren Commission Exhibit 399), which critics have been claiming could not have penetrated both President Kennedy's neck and Governor Connally's thorax and wrist and still remain undeformed, was found by these investigators to be, in fact, deformed (flattened) in a manner which required great force to duplicate on test bullets from the same lots. The four fragme...

The presence of a migratory bullet in the spinal canal after a gunshot injury is a rare finding, specially without causing permanent neurologic damage. We present the case of a patient who suffered a gunshot wound with an entry point in the posterior arc of L2-L3 and a migratory bullet detected at the level of L5-S1 in the CT scan. The patient complained about intense headache, dizziness, and v...

This paper describes a study of Bullet Rounds in General Internal Medicine at an urban teaching hospital in Toronto, Canada. Bullet Rounds are multidisciplinary meetings of healthcare professionals involved in patient care. The goal of the study was to examine the processes of the meetings to understand the level of collaboration and knowledge exchange that takes place, the issues faced by such...

Bullet embolization cases are rare and even rarer are its retrograde migration in the veins. We report the case of a 14 year old male with a gunshot wound to the left side of his chest. CT scan revealed bilateral haemothorax and foreign body in the right common iliac vein. The patient was immediately taken to the operating theatre and median sternotomy performed. Bullet entry tear was found in ...

In a previous paper, we showed that discrete version of the $S_\bullet$-construction gives an equivalence categories between unital 2-Segal sets and augmented stable double categories. Here, generalize this result to homotopical setting, by showing there is Quillen model category for objects Segal which given $S_\bullet$-construction. We show fits together with in case briefly discuss how it en...
