[The most frequent organisms in open fractures in Mexico].

Unlabelled: An open fracture is one in which the bone segments penetrate into the skin leaving the bone in contact with the outer environment. Many microorganisms may cause wound infection in open fractures; the most common one is Staphyloccocus aureus.

Methods: This study included a group of 75 patients of both genders seen from November 1st, 2009 to April 30, 2010.

[Traumatic hip dislocation in pediatric patients. Report of 5 cases].

We present five cases of patients with traumatic hip dislocation diagnosed clinically, with X-rays and CT scan. Closed reduction was performed under IV sedation and fluoroscopic control. Patients wore a Dennis Brown brace at 45 degrees of abduction and neutral rotation.

[Bilateral quadriceps rupture in a patient with osteogenesis imperfecta. A case report].

We present the case of a 24-year-old patient with bilateral quadriceps rupture and history of type I congenital osteogenesis imperfecta diagnosed clinically and with ultrasound. Bilateral quadriceps tenoplasty was performed with an anterior approach and without any complications. The patient was discharged with bilateral neoprene knee-guards.

[Amputation as a treatment for complications on a traumatic dislocations of the knee. Case report].

Introduction: Vascular lesion associated with knee dislocation represents a common and potentially devastating complication. A delay in revascularization that exceeds 8 hours can lead to amputation of the extremity. Therefore it is mandatory to do an immediate examination and an effective diagnosis to rule out this complication.

[An evaluation of the efficacy of nitrates (transdermal and peroral) in the management of the patient with a myocardial contusion].

Although thoracic trauma is frequently accompanied by myocardial injury; this later is often oversighted at early stages of trauma and misdiagnosed by the time complications are present. Myocardial abnormalities have been attributed to a reduction of cardiac flow. Nitroglycerin and isosorbide dinitrate, both agents with a known vasodilator effect on coronary arteries, might improve myocardial ischemic resulting from traumatic contusion.

[Orthodontic-surgical treatment for correction of maxillary deficiency. LeFort I osteotomy].

Class III dentofacial deformities have been corrected by isolated orthodontic and/or surgical procedures, the facial a esthetics results of this approach are frequently less than optimal. The purpose of this article is to present our orthodontic-surgical approach, which has proved successful functional and esthetic results. Two representative cases are illustrated.

[Gingival smile: surgical-orthodontic treatment].

The treatment of patients with dentofacial deformities which include excessive exposure of frontal upper teeth and upper alveolar gum at resting and/or dynamic position of the lips, is a frequent challenge to odontologists, orthodontists, prosthesists and maxillofacial surgeons. This article introduces a joint orthodontic-surgical approach for the functional and esthetic correction of this deformity. Attained results are illustrated by two representative case histories.

[Complex compound odontoma cystic eruption].

An erupted cystic complex odontoma's case is reported. Histological, radiographic and clinic/fractures were considered. Erupted odontomas are unusual lesions; we did not find similar case reported in the literature.
