Review Case Reports
[Vibrio vulnificus in Mexico: a case report and review of the literature].
Vibrio vulnificus is an etiologic agent of septicemia and skin lesions. Patients with chronic diseases, and more frequently chronic liver disease, are specially susceptible to this infection. ⋯ The patient had ingested shrimps two days before. A review of the recent literature on the subject is also presented.

Traditionally, the renin angiotensin system (RAS) has been thought of primarily as an endocrine system that delivers circulating angiotensin II to target tissues. This peptide is a potent vasoconstrictor and a primary stimulus for aldosterone secretion. In addition, angiotensin II has many other targets such as kidney, heart and brain, from which it elicits different specific responses. ⋯ It has been proposed that the main function of the circulating RAS is to provide short-term cardiorenal homeostasis. The tonic control (e.g., adrenal and kidney) is influenced by the intrinsic tissue RAS. This new concept provides a broader outlook on the RAS and challenges its traditional endocrine role.

Review Case Reports
[Embolism caused by a bullet. Report of a case and review of the literature].
We describe the case of a 23 years old male, who suffered a 45 bullet wound in the arm and upper right hemithorax. He walked after his injury and 10 minutes later presented dizziness, cough and tachycardia. On admission a minor haemothorax was seen on a chest X ray, but the bullet was not seen. ⋯ Through a posterolateral thoracotomy the slug was obtained. The recovery was uneventful and he has remained well since. We discuss the possible mechanisms to explain the entrance of the bullet into the vascular system and conclude that in cases of gunshot wounds: a) An exit wound must be always searched for; if not found exploratory X ray are mandatory, b) If the bullet is not found, specially after thoracic injuries, bullet embolism should be contemplated, c) If there are signs of regional ischemia arteriography is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)
