1/7. subcutaneous emphysema of a digit through a pre-existing puncture wound.A case of injection of compressed air into a digit is reported. The air was injected at 50 PSI through a trivial puncture wound sustained some hours previously. The case had a benign course, in comparison to high pressure injection injuries with foreign material.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
2/7. Cervical emphysema, pneumomediastinum, and pneumothorax following self-induced oral injury: report of four cases and review of the literature.Spontaneous rupture of the pulmonary alveoli after a sudden increase in intra-alveolar pressure is a common cause of pneumomediastinum, which is usually seen in healthy young men. Other common causes are traumatic and iatrogenic rupture of the airway and esophagus; however, pneumomediastinum following cervicofacial emphysema is much rarer and is occasionally found after dental surgical procedures, head and neck surgery, or accidental trauma. We present four cases of subcutaneous emphysema and pneumomediastinum with two secondary pneumothoraces after self-induced punctures in the oral cavity. They constitute an uncommon clinical entity that, to our knowledge, has not been reported in the literature. Its radiologic appearance, clinical presentation, and diagnosis are described.- - - - - - - - - - ranking = 0.2keywords = puncture (Clic here for more details about this article) |
3/7. Pacemaker malfunction due to subcutaneous emphysema.We describe a pacemaker-dependent patient who presented with malfunction two days after implantation of a physiologic dual-chamber pacing system. The malfunction was due to subcutaneous emphysema produced by subclavian venepuncture. Accumulation of air within the generator pocket of the pacemaker resulted in insulation of the unipolar anodal plate and dysfunction of the device.- - - - - - - - - - ranking = 0.2keywords = puncture (Clic here for more details about this article) |
4/7. An unusual complication following tracheo-esophageal puncture for alaryngeal voice restoration.A laryngectomized patient who developed massive subcutaneous emphysema, pneumothorax, pneumomediastinum, and esophageal fistula with a retroesophageal collection following the creation of a tracheo-esophageal fistula for alaryngeal voice restoration is presented, together with its management. A review of the literature is made, and possible causes of the three complications are discussed.- - - - - - - - - - ranking = 0.8keywords = puncture (Clic here for more details about this article) |
5/7. infection emanating from an 'innocent' facial puncture wound. case reports.All accidental wounds are contaminated by bacteria. The factors involved in the conversion of a wound from contaminated to infected are identical, irrespective of the site and classification of the wound, although puncture wounds are particularly suited for the growth of anaerobic organisms. A case is presented of facial infection emanating from an 'innocent' puncture wound. The management of orofacial puncture wounds is discussed and illustrated with a second case.- - - - - - - - - - ranking = 1.4keywords = puncture (Clic here for more details about this article) |
6/7. Distant entry pneumothorax in a competitive fencer.An elite level fencer sustained a penetrating wound to the upper arm after his opponent's blade broke. Standard care for a deep puncture wound was given but it was some time before the athlete presented symptoms of a pneumothorax, which was confirmed by radiograph. Although resolution of this case was unremarkable, the possibility of penetrating thoracic injury, even when the point of entry is well outside the thorax and the athlete is not immediately symptomatic, should be born in mind by medical personnel working with fencers.- - - - - - - - - - ranking = 0.2keywords = puncture (Clic here for more details about this article) |
7/7. Pneumomediastinum following penetrating oral trauma.Pneumomediastinum can result from a puncture wound or laceration to the hypopharynx. This is a case report of an 18-month-old child who fell with a pen in his mouth. Initial physical examination was unremarkable, but the child developed neck swelling, fever, and irritability over the next 12 hours. Repeat examination revealed marked pneumomediastinum and subcutaneous emphysema. The pathophysiology and treatment of pneumomediastinum are reviewed.- - - - - - - - - - ranking = 0.2keywords = puncture (Clic here for more details about this article) |
