RESUMEN

The purpose of this work is to estimate our anatomical and functional results of the surgical technique based on the AO principle of tension band wiring. We led a retrospective continuous study on the basis of 70 files brought together from January, 1999 till December, 2006. We had included all the patients who presented a recent fracture of the olecranon treated by tension band wiring and having a follow-up more than 6 month. Seven (7) files were excluded giving to the study one population of 63 patients. The fracture was classified according to the classification of Mayo clinic and the associated hurts were noted. The tension band wiring was the exclusive treatment. The evaluation looked for the complications and appreciated the radiological and functional results according to the score of Mayo Elbow Performance Score. We had found 48 fractures of type II and 15 fractures of type III. There were 5 cases of cutaneous punctiforme opening, a fracture of the ipsilateral forearm in 3 cases, a fracture of the thighbone in 1 case and a dislocation of the elbow associated with a fracture of the humerus in 1 case. The consolidation was obtained at 60 patient's at the end of 4 months on average (extremes: 3 and 6 months). There were 3 cases of non union and 5 cases of pins migrations. On the functional plan, we obtained 15 very good results, 26 good results, 19 average results and 3 bad results. The most frequent and the most common fractures of the elbow, the olecranon fractures treated by tension band wiring give good results.

RESUMEN

Le but de ce travail est d'evaluer les resultats anatomiques et fonctionnels du traitement chirurgical des fractures de l'olecrane base sur le principe du hauban de l' Associa- tion suisse d'Orthopedie (A.O.*). Nous avons mene une etude retrospective continue sur la base de 70 dossiers colliges de Janvier 1999 a Decembre 2006. Nous avions inclus tous les patients qui presentaient une fracture de l'olecrane recente traite par haubanage et ayant un suivi superieur ou egal a 6 mois. Sept (7) dossiers ont ete exclus don- nant a l'etude un population de 63 patients. La fracture a ete classee selon la classification de la Mayo clinic et les lesions associees ont ete notees. Le haubanage a ete le traitement exclusif. L'evaluation a recherche les complications et a apprecie les resultats radiologique et fonctionnel selon le score de la Mayo Elbow Performance Score. Nous avions retrouve 3 fractures de type I; 48 fractures de type II et 12 fractures de type III. Il y avait 5 cas d'ouverture cutanee punctiforme; une fracture de l'avant-bras homolaterale dans 3 cas; une fracture du femur dans 1 cas et une luxation du coude associee a une fracture de l'humerus dans 1 cas. La consolida- tion a ete obtenue chez 60 patients au bout de 4 mois en moyenne (extremes : 3 et 6 mois). Il y a eu 3 cas de pseudarthrose et 5 cas de migration de broches. Sur le plan fonctionnel; nous avons obtenu 15 tres bons resultats; 26 bons resultats; 19 resultats moyens et 3 mauvais resultats. Plus frequentes et plus communes des fractures du coude; les fractures de l'olecrane traitees par haubanage donnent de bons resultats

RESUMEN

The authors evaluated the management of malunions of midshaft fractures of the radius and ulna in an Orthopedic and Traumatology departement at Le Dantec University hospital (Dakar, Sénégal). Over a six-year period, there were 10 cases found for analysis. All patients presented with disabilities due to limited pronosupination. Surgical care improved the pronosupination amplitude in all patients. The role of conservative treatment of these fractures in causing malunion is discussed. Correction of these malunions should be by osteotomy, followed by rigid internal fixation with a plate and screws.

RESUMEN

Bipolar clavicular dislocation is uncommon. It associates an acromioclavicular and sternoclavicular dislocation. The authors review the mechanism of this injury and discuss the treatment. Three patients presented after a trauma of the shoulder a floating clavicle. In 2 patients management was surgical. Abstention was decided for the fourth patient. The pathology of floating clavicle is not completely understood. Two hypothesis were made: 1) two dislocations occur simultaneously; 2) two dislocations occur one after another. Management still difficult. Indications must take into considerations the severity of the injury and the functional consequences in the acromioclavicular joint.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of the use of nebulized L-epinephrine associated with dexamethasone in postintubation laryngitis. METHODS: We carried out a prospective, randomized, double-blind, placebo controlled study with two cohorts of patients with postintubation laryngitis graded 3 to 6 by Downes-Raphaelly score during two years. Our population was divided into two groups: A and B; both groups received intravenous dexamethasone and two doses of nebulized saline; however, only group B received L-epinephrine. The efficacy was assessed by Downes-Raphaelly score. The side effects of L-epinephrine were evaluated according to the occurrence of cardiac arrhythmia, increased blood pressure, and average heart rate of group B in comparison to group A. RESULTS: Twenty-two patients were included in group A (average score = 4.8) and 19 in group B (average score = 5.2). During treatment, 3 patients in group A presented a score of 8 and were reintubated. This group also showed higher mean clinical scores than group B during the first two hours of the protocol; these results were not statistically significant. No side effects were observed due to epinephrine. The gas blood measurements were adequate in both groups, but better in the control group. CONCLUSIONS: We did not observe increased efficacy for the treatment of postintubation laryngitis when nebulized L-epinephrine was used simultaneously with intravenous dexamethasone. Some indicators, however, did present a favorable trend when combined therapy was used and should be submitted to further evaluation.

RESUMEN

OBJECTIVE: The authors evaluate the therapeutic efficacy of two antibiotic schedules, ceftriaxone alone and the combined use of ampicillin and chloramphenicol, in the treatment of septic children with purpuric presentation.METHODS: A randomized open clinical trial was conducted including septic children with purpuric presentation treated at a pediatric intensive care unit from April 1988 to June 1992. All cases with systemic purpura standing for less than a week were included in one of two groups, except for those recently hospitalized or with previous hemorrhagic disturbs. Patients in group A received ampicillin and chloramphenicol and those in group B were given ceftriaxone. Quantitative parameters were adopted to compare the efficacy of the two antibiotic schedules: sensitivity of bacteria isolated at blood and liquor cultures, complications, therapeutic procedures, period of hospitalization, and sequelae.RESULTS: 19 cases were included in the group A and 16 in group B, both homogenous on clinical-laboratorial aspects. The parameters evaluated did not show different efficacy between the two antimicrobial schedules tested, except for the number of complications observed during hospitalization, which was higher among the children that received ampicillin and chloramphenicol. The overall mortality for the patients treated was 13.8%, excluded the undernourished. CONCLUSIONS: The authors verify similar clinical therapeutic efficacy with the combined use of ampicillin and chloramphenicol or ceftriaxone, as observed previously. It must be pointed that the number of complications detected during hospitalization were higher in the group that received the combined antibiotic schedule. Low mortality in the present study may be attributed to the early diagnosis and therapeutic measures adopted at the pediatric intensive care unit.

RESUMEN

OBJECTIVE: To evaluate the efficacy of dexamethasone as an auxiliary therapeutic tool to the antibiotics in hospitalized children with meningococcal meningitis. METHODS: A retrospective clinical comparative study was undertaken with children from a pediatric ward affected by laboratory proved meningococcal meningitis at a university hospital. Cases of children in state of shock at admission or deceased in the first 24 hours were excluded. During the period from 1987 to 1989 33 children were treated only with antibiotics (group A), while from 1990 to 1993 other 66 children received additionally dexamethasone (12mg/m2/24h) by intravenous route during four days beginning at the admission to the hospital (group B). The two groups were evaluated at baseline through prognostic scores and analysis of their clinical and laboratorial characteristics obtained from data recorded at the admission. The parameters to evaluate dexamethasone efficacy were the comparative number of neurologic and systemic complications detected at the hospital, and the liquoric profile (leukocyte count, glucose and protein content) verified between day 9 and day 11 of hospitalization. RESULTS: The profile of the two groups (A and B) were homogeneously evaluated by the illness severity scores and their clinical and laboratorial characteristics. Nine complications were recognized in group A (27.2%) and 21 (31.8%) among those of group B, difference not significant. Likewise, there were not observed liquoric differences between the two groups related to the chimiocytologic pattern. CONCLUSIONS: No effect of dexamethasone therapy to prevent neurologic and systemic meningococcal meningitis complications was observed during hospitalization. Similarly no favorable effect in relation to the liquoric pattern verified between day 9 and day 11 of hospitalization was recognized.

RESUMEN

The jararacuçu, one of the most dreaded snakes of Brazil, southern Bolivia, Paraguay and northeastern Argentina, is a heavily-built pit viper which may grow to a length of 2.2 m. Up to 1000 mg (dry weight) of highly-lethal venom may be milked from its venom glands on a single occasion. It has accounted for 0.8% to 10% of series of snake bites in São Paulo State, Brazil. We examined 29 cases of proven jararacuçu bites recruited over a 20-year period in two São Paulo hospitals. Severe signs of local and systemic envenoming, (local necrosis, shock, spontaneous systemic bleeding, renal failure) were seen only in patients bitten by snakes longer than 50 cm; bites by shorter specimens were more likely to cause incoagulable blood. Fourteen patients developed coagulopathy, six local necrosis (requiring amputation in one) and five local abscesses. Two became shocked and four developed renal failure. Three patients, aged 3, 11 and 65 years, died 18.75, 27.75 and 83 h after being bitten, with respiratory and circulatory failure despite large doses of specific antivenom and intensive-care-unit management. In two patients, autopsies revealed acute renal tubular necrosis, cerebral oedema, haemorrhagic rhabdomyolysis at the site of the bite and disseminated intravascular coagulation. In one survivor with chronic renal failure, renal biopsy showed bilateral cortical necrosis; the patient remains dependent on haemodialysis. Effects of polyspecific Bothrops antivenom were not impressive, and it has been suggested that anti-Bothrops and anti-Crotalus antivenoms should be given in combination.
