[Treatment of pediatric humeral supracondylar fractures with a lateral external fixator. A case report].

We present the case of a child with a Gartland III humeral supracondylar fracture treated with a lateral external fixator and 1.6 mm Kirschner nails. The edema and postoperative pain subsided and the patient had early mobility, thus avoiding the use of cast immobilization.

[Treatment of distal humeral shaft fractures at Polanco Mexican Red Cross].

Objective: To determine which is the most effective treatment for the management of soft tissues, the functional recovery and the healing of distal third humeral shaft fractures at the Mexican Red Cross trauma center.

Material And Methods: This is a retrospective, longitudinal, comparative study of patients with a diagnosis of distal third humeral shaft fractures; clinical and radiographic follow-up was done with the MEPI, UCLA and Montoya functional scales at week 24.

Results: The results of patient follow-up using the MEPI in Group I were: 2 poor, 3 fair, 1 excellent; in Group II: 8 excellent; in Group III: 3 poor, 2 fair, 4 excellent; in Group IV: 1 poor, 5 fair and 2 excellent.

Cytomegalovirus gB genotype distribution in Mexican children undergoing allogeneic bone marrow transplantation.

We used nested multiplex polymerase chain reaction to determine the distribution of cytomegalovirus gB genotype in 30 Mexican children undergoing bone marrow transplantation. The genotypes were: gB1, 9/30 (30%); gB2, 8/30 (27%); gB3, 4/30 (13%), and gB4, 1/30 (3%); mixed genotypes were identified in 8/30 patients (27%). We conclude that the predominant genotypes identified were gB2 and gB1.

The role of cytomegalovirus infection and disease in pediatric bone marrow transplant recipients in Mexico City in the context of viral drug resistance.

We aimed to identify those pediatric patients undergoing ABMT with CMV EOD who developed GCV resistance. Forty-seven patients were analyzed following ABMT. Prospective post-transplant CMV monitoring was performed weekly for the detection of viral leukocyte DNAaemia, viral plasma DNAaemia, and viral DNAuria by PCR.

[Experience in the management of open pelvic fractures at the Mexican Red Cross Trauma Center].

A prospective, descriptive study was conducted at the Trauma and Orthopedics Service from January 1st, 2006 to January 1st, 2009; all patients with a diagnosis of open pelvic fracture were included. A total of 112 patients with pelvic fracture were seen at the Emergency Room; 12 of them with an open pelvic fracture; 75% were males, most of them ages 31 to 45 years of age; they were stabilized with a circular pelvic binder and external fixators with a V technique; a gastrointestinal bypass with colostomy was performed; 3 patients died within the first few hours due to hypovolemic shock, 5 survived a mean of 25 days and died due to other causes, and four patients were discharged alive. These lesions have a mortality rate of 66.

[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.

[Treatment of shaft fractures in children with elastic titanium nails].

Unlabelled: According to the statistics, long bone fractures in children are caused by high-energy mechanisms and they are the most frequent ones in the orthopedic practice. The advantage of reducing these fractures with elastic titanium nails and three buttress points is that neither the blood supply nor the physis are injured.

Material And Methods: Twenty-seven patients ages 5-15 years of age were analyzed.

[Clinical and functional assessment in the treatment of os calcis fractures. Open and closed reduction].

In this prospective, longitudinal, comparative, observational study 15 patients with 17 fractures were reviewed from September 1st 2006 to December 31st 2007 and followed-up by the outpatient service at 4, 8, 12, 16 and 20 weeks and at one year. All patients were assessed with the Maryland functional scale. These fractures were more frequent among males, 94%, and mean age was 35 years.

[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.

[Damage control in long bones and pelvis in the Mexican Red Cross Trauma Center].

Multiple injured patients account for some of the biggest and most complex problems a trauma surgeon has to face in his daily routine; thus, applying orthopedic damage control (DCO) is important. Multiple injured patients treated at the Medical Red Cross Medical Trauma Center were reviewed, in the period comprised between June 2006 and July 2007. One-hundred cases with long bone and pelvis fractures, ranging between 10 and 75 years old, 21 women (21%) and 79 men (79%); the most common trauma mechanism was patients falling from a height above 2 meters (33%).

[The prognosis of thrombocytopenic purpura using predictive criteria evaluation by multivariate analysis methods].

The development of predictive systems with the resources of multivariate analysis let us to do gradually a more objective medicine. In this study we correlate a set of characteristics observed in 39 patients with thrombocytopenic purpura during the first week of medical treatment against the score of severity of the whole purpuric disorder, evaluated a the 25 week of evolution. It was accomplished with a model of multiple logistic regression of successive steps which let us to get the weights of each one of the indicants in order to predict the severity of the whole hemorrhagic diathesis.

[Various genetic and clinical aspects of patients with hemolytic anemia caused by glucosephosphate dehydrogenase deficiency (DG6F)].

Five families with DG6F deficiency were studied. Out of the first family, neinatal hyperbilirubinemia was evident in 3 children. Exchange transfusion was given to the first two.
